FIG. 2 shows a conveying assembly 70 including a supporting member 71, four sliding members 73, two fixing members 75, eight latching members 77, eight locking members 78, and eight rollers 79. The supporting member 71 is configured for supporting workpieces. The four sliding members 73 are mounted on four corners of the supporting member 71, accordingly, and are received in the sliding grooves 13. The sliding members 73 are slidable along the sliding grooves 13 which are parallel with each other, in such a way that allows the supporting member 71 to be slidable along the sliding grooves 13. The fixing members 75 are mounted on the supporting member 71, and are configured to fix the latching members 77, the locking members 78, and the rollers 79. Four of the eight latching members 77 are fixed on one corresponding fixing member 75. Each locking member 78 is latched with one corresponding latching member 77. Each roller 79 is rotatably mounted on one corresponding locking member 78, and contacts with the rolling member 50. The rolling member 50 rotates to drive the rollers 79 to rotate along the rolling member 50, which results in the conveying assembly 70 sliding along the supporting platform 10.
The supporting member 71 includes a main body 711 and a pair of extending portions 713 perpendicularly extending from opposite ends of the main body 711 towards the supporting platform 10. The main body 711 and the extending portions 713 cooperatively define a receiving chamber 715, for receiving the fixing members 75, the latching members 77, the locking members 78, and the rollers 79. The main body 711 is substantially a rectangular plate, and includes a supporting surface 7111 (shown in FIG. 1) located at a side away from the extending portions 713. The supporting surface 7111 is configured to support workpieces. Each extending portion 713 defines a containing groove 7131 at a distal end thereof away from the main body 711, for receiving the sliding members 73. Each two of the four sliding members 73 are fixed within one corresponding containing groove 7131. Each sliding member 73 includes a rotating portion 731 and a fixing rod 733. The fixing rod 733 rotatably passes through a middle portion of the rotating portion 731. Opposite ends of the fixing rod 733 are fixed with opposite inner sidewalls of the containing groove 7131. The rotating portions 731 of the four sliding members 73 are partially received in the sliding grooves 13, which enable the conveying assembly 70 to slide along the sliding grooves 13.
The fixing members 75 are fixed on a surface of the main body 711 opposite to the supporting surface 7111, and are arranged at substantially two opposite ends of the main body 711. The fixing members 75 are received in the receiving chamber 715. Each fixing member 75 includes a mounting surface 751 adjacent to the supporting platform 10 corresponding to an outer sidewall of the rolling member 50. The mounting surface 751 is substantially arcuate. The mounting surface 751 defines a pair of fixing grooves 753 arranged apart, and parallel to each other. The fixing grooves 753 are parallel to the containing grooves 7131, for mounting the latching members 77.
Each four of the eight latching members 77 are mounted on one corresponding mounting surface 751, and each two latching members 77 are mounted on one corresponding fixing groove 753 of one corresponding fixing member 75, and are arranged apart along the fixing groove 753. Each latching member 77 defines a receiving hole 771 along an axis thereof, and is a substantially hollow cylinder. An inner sidewall of the receiving hole 771 defines a plurality of latching grooves 773 evenly spaced from each other, and are parallel to the axis of the latching member 77, for locking the locking member 78. In the illustrated embodiment, there are six latching grooves 773 for each latching member 77.
Each locking member 78 is inserted into the receiving hole 771, and is substantially cylindrical, for matching with the shape of the receiving hole 771. Six latching portions 781 are evenly spaced and protruding from an outer sidewall of the locking member 78 corresponding to the latching grooves 773. The locking member 78 defines a containing chamber 783 along an axis, for containing one corresponding roller 79. The locking member 78 is inserted into the receiving hole 771, and the latching portions 781 are latched with the latching grooves 773, so that each locking member 78 is assembled with one corresponding latching member 77. In other embodiments, the number of the latching grooves 773 can be two, three, four, or more, and the number of the latching portions 781 is equal to the number of the latching grooves 773. The latching grooves 773 can be defined on the locking member 78, and the latching portions 781 can protrude from the latching member 77 in one of the other embodiments.
Each of the eight rollers 79 is inserted into one corresponding containing chamber 783. Each of the eight rollers 79 includes a rolling portion 791 and a fixing shaft 793. The fixing shaft 793 passes through a middle portion of the rolling portion 791, and opposite ends of the fixing shaft 793 are fixed with an inner sidewall of the containing chamber 783 with an included angle formed relative to the extending portions 713, thereby the rolling portion 791 is assembled with the locking member 78. A rotation axis of the rolling portion 791 is defined as a rotation axis B (shown in FIG. 3), and the rotation axis B inclines relative to the extending portions 713 in an abuse angle or in an acute angle. When the conveying assembly 70 is mounted on the supporting platform 10, the rolling portion 791 resists against the rolling member 50, and the rotation axis B of the roller 79 inclines relative to the rotation axis A of the rolling member 50 with an included angle defined as θ (shown in FIG. 3). The rollers 79 can be adjusted to other included angles relative to the extending portions 713 via having the latching portions 781 latched with the latching grooves 773 in other assembling orders. Therefore, the included angle θ of the rotation axis B relative to the rotation axis A can be adjusted by adjusting an assembling order of the locking members 78 with the latching members 77.
The positioning assembly 90 (shown in FIG. 1) includes a second driving member 91 and a positioning block 93. The second driving member 91 is located on a fixing platform (not shown) besides the supporting platform 10. The positioning block 93 is mounted on an end of the second driving member 91 towards the supporting platform 10. The second driving member 91 drives the positioning block 93 to move to the top surface of the supporting platform 10, the conveying assembly 70 is then stopped. Therefore, the workpieces on the supporting surface 7111 are positioned. In the illustrated embodiment, the second driving member 91 is a cylinder.
In assembly, the rolling member 50 is mounted on the supporting platform 10 via the mounting members 40, and the rolling member 50 is received in the receiving groove 11. The first driving member 30 is mounted on a distal end of the rolling member 50. The second driving member 91 is positioned on the fixing platform located besides the supporting platform 10, and the positioning block 93 is positioned at a side of the second driving member 91 towards the supporting platform 10. The four conveying assemblies 70 are put on the top surface of the supporting platform 10 one by one. The sliding members 73 are received in the sliding grooves 13, and the rollers 79 resist on a cylindrical outer sidewall of the rolling member 50.
In use, a plurality of workpieces are put on the supporting surface 7111. The first driving member 30 drives the rolling member 50 to rotate. The rotation of the rolling members 50 applies a force defined as F0 to the rolling portion 791. A direction of the force F0 overlaps with a tangent line of the rolling member 50. The resolution of the force F0 is shown in FIG. 3. The force F0 is resolved into a split force F1 along a tangent line of the rolling member 50 and a split force F2 parallel to the axis A of the rolling member 50. The rolling portion 791 is driven by the split force F1 to rotate relative to the fixing shaft 793. The split force F2 drives the rollers 79 to slide along the rolling member 50, thus the sliding members 73 slide along the sliding grooves 13, and the supporting member 71 moves relative to the supporting platform 10. Therefore, the workpieces are conveyed by the conveying assemblies 70. When the workpieces are needed to be positioned, the second driving member 91 drives the positioning block 93 to protrude out of the top surface of the supporting platform 10, so that the conveying assembly 70 and the workpieces are positioned by the positioning block 93.
Because the rotation of the rolling member 50 drives the rollers 79 to slide along the rolling member 50, it makes lesser noise when conveying workpieces, and the conveying assembly 70 slides more easily along the rolling member 50. In addition, the positioning assembly 90 can easily position the workpieces during the conveying process.
In other embodiments, the latching members 77 or the rollers 79 can be directly mounted on a bottom surface of the supporting member 71, or the rollers 79 may be directly mounted on the mounting surface 751, but the rotation axis of the rolling member 50 needs to be inclined relative to the rotation axis of the roller 79 in an abuse angle or in an acute angle. The number of the rollers 79 may be one, two, three, four, or more than four, the number of the latching members 77 and the number of the locking members 78 may be one, two, three, four, or more than four corresponding to the number of the rollers 79.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
