Specifically, the at least one dust particulate absorber device(s) 11 and the wiper device 12 are arranged horizontally, that is, each of the dust particulate absorber device 11 is provided at any one of the four perimeter sides around the wiper device 12, and parallel to the wiper device 12 in the horizontal direction. Because the detection of the display panel has a relative high requirement as to the cleanliness of the work table, the cleaning apparatus 1 provided by the embodiment of present invention may also be used for cleaning a work table. The cleaning apparatus 1 provided by the embodiment of present invention may comprise at least one dust particulate absorber device(s) 11 and a wiper device 12, wherein the dust particulate absorber device(s) 11 may be used for preliminary absorption of the foreign matters on the work table, and the wiper device 12 is used to further wipe the work table subsequently. Alternatively, the step of adsorbing the foreign matters on the work table by the dust particulate absorber device 11 may be performed prior to, during, or after the wiping process.
The embodiment of present invention provides a cleaning apparatus 1, which is used to clean the work table on which the display panels are mounted during the detection of the display panels, so as to avoid various potential safety risks and damages to the apparatus caused by manual cleaning. Additionally, the cleanliness level is increased.
For example, in another embodiment of the present invention, as shown in FIGS. 1 and 2, the wiper device 12 may comprise two accommodation chambers, each of which is provided with one roller 101, a sheet of non-dust cloth 103 having its two ends wound around the two rollers 101 respectively, wherein the non-dust cloth 103 at least covers the bottom portion of the cleaning apparatus, and the roller in one of the accommodation chambers is a driving shaft.
To be specified, in an embodiment of present invention, the non-dust cloth 103 may be a sheet of clean cloth, or a sheet of any paper product with proper resilience, or similar items that may be wound around the rollers and used for wiping and cleaning. The non-dust cloth 103 at least covers the bottom of the cleaning apparatus 1. Then, the cleaning apparatus 1 wipes and cleans the work table with the non-dust cloth 103 arranged at the bottom.
For example, in another embodiment of the present invention, as shown in FIG. 2, several feeding shafts 102 may be provided between the two rollers 101 for feeding the non-dust cloth 103. The transfer shafts 102 may be pulleys, slide blocks or similar members.
For instance, in still another embodiment of the present invention, the cleaning apparatus may further comprise an electrical motor module 18 to drive the driving shaft. For example, the electrical motor module 18 may be an electrical motor.
To be specified, the electrical motor module 18 drives the driving shaft, then the section of the non-dust cloth 103 at the bottom of the cleaning apparatus 1 is wound around the driving shaft after wiping. Thus, reuse of the non-dust cloth which would otherwise reduce the clean quality is prevented. To be specified, the used non-dust cloth 103 is wound around the driving shaft by the rotation of the driving shaft while the used non-dust cloth 103 is lifted from the work table. For example, before the cleaning apparatus start to clean the work table or after the cleaning apparatus has wiped part of the work table, the cleaning apparatus is lift up and then the electrical motor module 18 drives the driving shaft. Subsequently, the section of the non-dust cloth have been used to wipe the work table is wound around the driving shaft through rotation of the driving shaft. After this, a section of fresh non-dust cloth 103 is covered at the bottom of the cleaning apparatus to continually clean the work table. Additionally, one of the accommodation chambers with no electrical motor module 18 connected thereto may be filled with cleaning liquid. The cleaning liquid may be water or solution dissolved with rinsing agent, and the rinsing agent is required to be incorrosive and volatile, so as to avoid contamination or damage to the work table and the display panel placed thereon. The dust particulate adsorption device 11 is used to adsorb the dust particulates. The cleaning liquid is used to keep the non-dust cloth 103 wet, and thus the wet non-dust cloth 103 is used to clean tiny dust on the work table, and so on. For example, the cleaning liquid is a volatile solution containing alcohols, for example, isopropanol and the like. Said composition facilitates rapid air drying of the wiped work table.
For example, in another embodiment of the present invention, as shown in FIG. 2, a resilient means 16 may be mounted at the bottom of the cleaning apparatus 1, and the non-dust cloth 103 is arranged to cover the resilient means 16. The resilient means 16 is in a convex configuration, as shown in FIG. 2. The resilient means is in an arcuate shape, such that the bottom of the cleaning apparatus 1 is raised. In addition, while the non-dust cloth 103 overlies the convex resilient means 16, the non-dust cloth 103 may fully contact with the surface of the work table. Thus, the cleanliness after wiping is elevated. For example, the resilient means 16 may be any elastomer, such as sponges, plastic foams, springs, and the like. Moreover, the resilient means 16 may also be disc-shape, square-shape and so on, as long as it can form a protrusive smooth surface so as to support the non-dust cloth 103 for wiping the work table.
For example, at the opposite sides of the wiper device 12 are each provided with one of the at least one dust particulate absorber device(s) 11. As shown in FIG. 2, at each of the left and right sides of the wiper device 12 is provided with one dust particulate absorber device 11.
At the two opposite sides of the wiper device 12 are each provided with one dust particulate absorber device 11. Then, during cleaning process, the cleaning apparatus may start to clean the work table from either side provided with the dust particulate absorber device 11. This is even more convenient. Subsequently, after the cleaning process by above said dust particulate absorber device 11 and the wiper device 12, another absorption process may further be conducted once more by the other dust particulate absorber device 11 to ensure the cleanliness of the work table.
For example, in another embodiment of the present invention, as shown in FIG. 2, the cleaning apparatus further comprises at least one airdry device(s) 13 which is arranged side by side with respect to the wiper device 12 and the dust particulate absorber device(s) 11, and at the two opposite sides of the wiper device 12 is provided with one of the airdry devices 13.
For example, the airdry device(s) 13 is arranged side by side with respect to the wiper device 12 and the dust particulate absorber device(s) 11, that is, they are arranged at the same horizontal plane. Because the non-dust cloth is soaked with cleaning liquid, the work table is wet after wiping process by the non-dust cloth of the wiper device 12. After the wiping process, the work table may be dried faster with the airdry device(s) 13. For example, there are two airdry devices 13, each of which is provided at one of the two opposite sides of the wiper device 12. In another example, the airdry devices 13 are each provided between the wiper devices 12 and the dust particulate absorber devices 11, and may also be provided at the outer sides of the dust particulate absorber devices 11. During each cleaning process by the cleaning apparatus, the dust particulate absorber device 11 at one side of the wiper device 12 and the airdry device 13 at the other side of the wiper device 12 could clean the work table simultaneously.
For example, in another embodiment of the present invention, the dust particulate absorber device(s) 11 communicates to the outside of the device, such that its possible to remove the absorbed dust particulates outside of the cleaning apparatus. Because the cleaning apparatus 1 has a small inner volume, the dust particulates absorbed by the dust particulate absorber device 11 may be removed outside of the cleaning apparatus, there is no need to frequently clean the dust particulates absorbed by the dust particulate absorber device. Accordingly, the cleaning effect is improved, the cleaning procedure is simplified, and the manpower and working hours required are reduced.
For example, in another embodiment of the present invention, the cleaning apparatus further comprises a control circuit 17 for controlling various components of the cleaning apparatus. The control circuit 17 is used to control each component of the cleaning apparatus in the cleaning operations. For example, the control circuit 17 may control the operations of the dust particulate absorber device(s) 11, the electrical motor module 18, the airdry device(s) 13 and the like, and thus further facilitate the manipulation and control of the cleaning apparatus. For example, the control circuit 17 may control the electrical motor module 18, and thus control the rotation of the driving shaft to feed and replace the non-dust cloth 103. The control circuit 17 may also control on and off of the dust particulate absorber device(s) 11 and the airdry device(s) 13, so as to coordinate the operations of the components to clean the work table with higher efficiency.
For example, in another embodiment of the present invention, the cleaning apparatus may further comprise a fixture member 15 for retaining the cleaning apparatus 1. To be specified, the fixture member 15 is used for fixing the cleaning apparatus 1. The fixture member 15 may be integrally formed with the cleaning apparatus. Alternatively, as shown in FIGS. 1 and 2, the fixture member 15 is provided on the top lid 14 of the cleaning apparatus. Alternatively, the top lid 14 may also be formed in any other shape and configuration. The top lid 14 is described here with reference to the drawings as an example.
In the embodiment of present invention, the cleaning apparatus 1 is mainly used to clean the detecting work table. Before cleaning the work table, the cleaning apparatus 1 may, with the fixture member 15, be fixed onto a connecting rod of the detecting device, which is used to fasten a detecting sensor. The cleaning apparatus 1 is controlled to clean the work table through the control circuit 17. For example, as required, the cleaning apparatus 1 could be controlled to move on the work table along a straight, a S-shape, or a W-shape route and the like by the control circuit 17, so as to ensure the cleanliness of the wiped work table.
All the above are just specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and various changes and alternation can be easily obtained by the skilled in this art within the disclosed technical scope by this invention, all of which should be encompassed in the protection reach of the present invention.
