## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2014-0123882, filed on Sep. 17, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its' entirety by reference.
TECHNICAL FIELD
The present disclosure relates to an automatic examination device of parts for a vehicle, and more particularly, to an automatic examination device of parts for a vehicle so that the parts can be automatically examined by moving a position of a part examining plate according to the different smart cruise control mounting positions for each different vehicle model.
BACKGROUND
In general, smart cruise control (SCC) for a vehicle is a unit capable of maintaining a proper distance from a preceding vehicle by automatically controlling a throttle valve, a brake, and a transmission of the vehicle using a position and a distance of the preceding vehicle. The SCC uses radar mounted on a front of the vehicle to gather data to perform proper acceleration or deceleration.
Since the above-mentioned SCC performs the acceleration or deceleration based on the position and distance with respect to the preceding vehicle, it is important to perform a condition confirmation examination for a part position when the smart cruise control is mounted in the vehicle.
However, according to the related art, if the position examination for the SCC mounted in the vehicle is not properly performed, the resulting examination device is not capable of properly recognizing a changed mounting position of the SCC even though the mounting position of the SCC is changed depending on a vehicle model. As a result, marketability and safety may be degraded.

Exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
As shown in FIGS. 1 to 3, an automatic examination device for parts of a vehicle according to an exemplary embodiment of the present disclosure includes a base plate 100 which is horizontally movable, a part examining plate 200 which examines a part P, and an elevating part 300 which vertically moves the part examining plate 200.
As shown in FIGS. 1 and 2, the base plate 100 is installed on a lower portion of a bottom surface of a facility line on which a vehicle is positioned and is provided so as to be horizontally movable, thereby making it possible to adjust a position of the part examining plate 200 to be described below.
In this case, the base plate 100 includes a lower plate 110 having a guide rail 111 formed on an upper surface 113 thereof, and an upper plate 120 positioned over the lower plate 110 and horizontally moving along the guide rail 111.
In addition, the base plate 100 is provided with a moving member 130, which enables the upper plate 120 to be horizontally moved.
Meanwhile, since the moving member 130 includes a cylinder part 131 mounted on the lower plate 110, and a connecting part 132 linked to the cylinder part 131 and connecting the lower plate 110 and the upper plate 120 to each other, the moving member 130 moves the connecting part 132 when the cylinder part 131 is operated, thereby making it possible to move the upper plate 120 with respect to the lower plate 110.
In this case, the lower plate 110 is additionally provided with an auxiliary rail 112, which may guide a movement of the connecting part 132.
The part examining plate 200 is formed in a plate shape as a configuration of automatically examining a part P (see FIG. 4) for the vehicle, thereby making it possible to examine a mounting position of the part P mounted in the vehicle.
The elevating part 300 is mounted on the base plate 100 and vertically moves the part examining plate 200, thereby making it possible to easily examine the mounting position of the part P.
That is, according to the present disclosure, the base plate 100 may be horizontally moved by the moving member 130 and the part examining plate may be vertically moved by the elevating part 300. The distances of movement may be changed depending on a setting.
Meanwhile, by providing a moving plate 230 on the part examining plate 200, when the part examining plate 200 is downwardly moved by the elevating part 300 after examining the part P as shown in FIGS. 6 and 7, the moving plate 230 is horizontally positioned on the bottom surface of the facility line to which the vehicle is provided, such that when the vehicle moves on the bottom surface of the facility line, the vehicle moves over the part examining plate 200, thereby making it possible to prevent an occurrence of interference upon the movement of the vehicle.
Here, the part P for the vehicle which is examined using the part examining plate 200 is a smart cruise control (SCC).
As shown in FIG. 4, the part examining plate 200 is provided with a plurality of corner reflectors 210, thereby making it possible to examine a mounting angle of the smart cruise control which is mounted in the vehicle.
During examination of the mounting angle of the smart cruise control using the corner reflector 210, a laser beam is transmitted from part P to the corner reflector 210. The laser beam is reflected and returned to a reflector provided in the smart cruise control as shown in FIGS. 4 and 5. The part examining plate 200 may examine the mounting angle of the smart cruise control mounted in the vehicle by calculating a difference between transmission and reception values. As shown in FIG. 5A, when the reflected laser beam returns to about the same spot as the origination, the part P is normally aligned. As shown in FIG. 5B, if the reflected laser beam returns to an offset point, so that the outgoing and return beams form an angle θ, then alignment of the part P correction is required.
In addition, the part examining plate 200 includes a sensing unit 220 which recognizes the vehicle and checks vehicle information to determine whether the vehicle is a vehicle model in which the smart cruise control is mounted by checking the vehicle in advance before examining the mounting position of the smart cruise control mounted in the vehicle using the automatic examination device of the parts for the vehicle according to the present disclosure, or to check different mounting positions of the smart cruise control since the mounting position of the smart cruise control is different depending on the vehicle model, thereby making it possible to improve work efficiency by a pre-examination work.
As such, since the automatic examination device of the parts for the vehicle according to the present disclosure includes the base plate 100 which is horizontally movable, the part examining plate 200 which automatically examines the smart cruise control, and the elevating part 300 which vertically moves the part examining plate 200, it may automatically examine the part P by moving the position of the part examining plate 200 depending on the vehicle model for the different mounting positions of the smart cruise control for each vehicle model. To this end, first, as shown in FIG. 3A, the vehicle is positioned on the facility line and a connector is connected to the vehicle, and thereby reads barcode and the like.
Next, as shown in FIGS. 3B and 3C, vehicle information may be received by upwardly moving the part examining plate 200 including the sensing unit 220 using the elevating part 300. The vehicle information may include whether the vehicle is a smart cruise control mounted vehicle model, and what the vehicle model is.
In the case in which the vehicle is a vehicle model for which it is unnecessary to horizontally move the part examining plate 200, the position of the smart cruise control mounted in the vehicle is examined in a state in which the part examining plate 200 is only upwardly moved as shown in FIG. 3D, and after the examination, the part examining plate 200 is downwardly moved as shown in FIG. 3E, thereby making it possible to move the vehicle in which the examination is completed.
Meanwhile, in the case in which the vehicle is a vehicle model in which it is necessary to horizontally move the part examining plate 200, the position of the smart cruise control mounted in the vehicle is examined in a state in which the part examining plate 200 is upwardly moved and is also moved to the right (i.e., horizontally) as shown in FIGS. 3F and 3G, and after the examination, the part examining plate 200 is moved to the center as shown in FIG. 3H, and the part examining plate 200 is then downwardly moved as shown in FIG. 3E, thereby making it possible to move the vehicle when the examination is completed.
In addition, as shown in FIG. 8, the automatic examination method of the parts for the vehicle according to the present disclosure includes a first operation (S10) of connecting a connector to the vehicle and reading barcode, a second operation (S20) of upwardly moving a part examining plate 200 and then determining whether or not a horizontal movement of the part examining plate 200 is required, a third operation (S30) of examining a position of a smart cruise control mounted in the vehicle when the horizontal movement is not required, a fourth operation (S40) of examining the position of the smart cruise control mounted in the vehicle by horizontally moving the part examining plate 200 when horizontal movement is required, and a fifth operation (S50) of downwardly moving the part examining plate 200.
In the first operation (S10), the vehicle is first positioned on the facility line, and once the vehicle is positioned on the facility line, a connector is connected to the vehicle for reading the barcode.
In the second operation (S20), the part examining plate 200 including a sensing unit 220 is upwardly moved using an elevating part 300, and after the movement of the part examining plate 200, it is determined whether or not the horizontal movement of the part examining plate 200 is further required.
In the third operation (S30), when horizontal movement of the part examining plate 200 is not required, the position of the smart cruise control mounted in the vehicle is examined in a state in which the part examining plate 200 has been upwardly moved.
In the fourth operation (S40), when the horizontal movement of the part examining plate 200 is required, the position of the smart cruise control mounted in the vehicle is examined in a state in which the part examining plate 200 has been upwardly moved, then moved left or right as required.
In addition, the automatic examination method of the parts for the vehicle according to the present disclosure further includes, after the completion of the position examination of the smart cruise control mounted in the vehicle in the third operation (S30) and/or the fourth operation (S40), a fifth operation (S50) of enabling a movement of the vehicle by downwardly moving the part examining plate 200 as shown in FIGS. 3E and 7.
As described above, according to the exemplary embodiment of the present disclosure, it is possible to improve workability and the reliability of examination by allowing the parts to be automatically examined according to the position of the smart cruise control mounted in the vehicle. In response to the particular position, the position of the part examining plate is adjusted according to the vehicle model for the different mounting positions of the smart cruise control to thereby flexibly deal with several vehicle models.
As described above, although the present disclosure has been described with reference to exemplary embodiments and the accompanying drawings, it would be appreciated by those skilled in the art that the present disclosure is not limited thereto but various modifications and alterations might be made without departing from the scope defined in the following claims.
