[0040] a robot arm assembly 200 for transporting the left luggage racks 600 or the right luggage racks 700 on the rotating disc 100 to the polishing station and performing a polishing path;

[0041] a clamping assembly 300 fixed on the robot arm assembly 200, the clamping assembly 300 comprising a first clamping unit and a second clamping unit, the first clamping unit comprising two first clamping blocks 310 that move towards or away from each other to clamp or release the left luggage racks 600, and the second clamping unit comprising two second clamping blocks 320 that move towards or away from each other to clamp or release the right luggage racks 700.

[0042] The first clamping unit for clamping the left luggage racks 600 and the second clamping unit for clamping the right luggage racks 700 are arranged in the same clamping assembly 300 in the present application, so that the clamping assembly 300 can clamp both the left luggage racks 600 and the right luggage racks 700, and thus only one robot arm assembly 200 is needed to drive the clamping assembly 300 to move, thereby carrying the left luggage racks 600 or the right luggage racks 700 to perform the polishing path, which reduces the polishing cost of the left luggage racks 600 and the right luggage racks 700.

[0043] Specifically, the clamping assembly 300 is fixed on the robot arm assembly 200, the robot arm assembly 200 drives the clamping assembly 300 to move to the rotating disc 100, the first clamping unit on the clamping assembly 300 clamps the left luggage racks 600 on the rotating disc 100, or the second clamping unit on the clamping assembly 300 clamps the right luggage racks 700 on the rotating disc 100, and then the robot arm assembly 200 drives the clamping assembly 300 to move to the polisher 400 to perform the polishing path.

[0044] Further, the first clamping unit has a gap between the two first clamping blocks 310, the first clamping unit is moved to the left luggage rack 600 in the gap between the two first clamping blocks 310, and then the two first clamping blocks 310 are closed to clamp the left luggage rack 600 between the two first clamping blocks 310. The two first clamping blocks 310 are away from each other, and the left luggage rack 600 can be released. Similarly, the second clamping unit is also the same.

[0045] Further, the clamping assembly 300 further comprises a mounting block 330 fixed with the robot arm assembly 200, and the first clamping unit and the second clamping unit are arranged on the mounting block 330.

[0046] The first clamping unit and the second clamping unit are simultaneously mounted on the same mounting block 330, which further reduces the volume of the clamping assembly 300, facilitates the execution of the polishing path, and reduces the cost.

[0047] Further, the two first clamping blocks 310 and the two second clamping blocks 320 are arranged along the length direction of the mounting block 330, and the two first clamping blocks 310 are between the two second clamping blocks 320.

[0048] Specifically, the left luggage rack 600 can be clamped between the two first clamping blocks 310, and the right luggage rack 700 can be clamped between the two second clamping blocks 320. The two first clamping blocks 310 and the two second clamping blocks 320 are on the same straight line, so that when the clamping unit clamps the luggage rack on different sides, the clamping assembly 300 only needs to be moved to the same position by the robot arm assembly 200, and then clamped by driving the first clamping unit or the second clamping unit, so as to realize clamping of the left luggage rack 600 or the right luggage rack 700. That is, when clamping the left luggage rack 600 and the right luggage rack 700, the position of the mounting block 330 relative to the luggage rack does not need to be adaptively adjusted, which simplifies the program setting of the robot arm assembly 200 and facilitates automatic polishing.

[0050] Further, the rotating table 110 is provided with a plurality of first clamping blocks 111, and the upper surface of the first clamping block 111 is recessed downward to form the first fixed part.

[0051] Further, the upper end of the fixing frame 120 extends a plurality of horizontal rods 121, the outer end of the horizontal rod 121 is fixedly connected with a second clamping block 122, and the outer side of the second clamping block 122 is recessed inward to form the second fixing part.

[0052] Specifically, one end of the luggage rack is inserted or clamped into the first fixing part, and the other end of the luggage rack is inserted or clamped into the second fixing part, so that the turntable 100 can constrain the luggage rack. Wherein, the machine arm assembly 200 drives the clamping assembly 300 to move to the turntable 100, the clamping assembly 300 clamps the luggage rack, and then the machine arm assembly 200 drives the clamping assembly 300 to move away, in the process of moving away, the clamping assembly 300 drives the luggage rack to separate from the turntable 100, so as to realize the clamping of the luggage rack.

[0053] Further, the side of the turntable 100 facing the machine arm assembly 200 has a clamping station, and the machine arm assembly 200 can clamp the left luggage rack 600 / right luggage rack 700 on the clamping station. Rotating the turntable 100 can move any left luggage rack 600 / right luggage rack 700 to the clamping station.

[0054] The clamping station is located on the turntable 100 closest to the machine arm assembly 200, so that the machine arm assembly 200 can move the shortest distance to realize the transfer of the luggage rack from the turntable 100 to the polishing machine 400; at the same time, since the clamping station is located on the side of the turntable 100 facing the machine arm assembly 200, when the machine arm assembly 200 clamps the luggage rack, the turntable 100 will not interfere with the machine arm assembly 200.

[0055] Further, it further comprises a storage rack 500, the storage rack 500 is sequentially provided with a first layer rack 510 and a second layer rack 520 along the height direction, the first layer rack 510 is used to place the left luggage rack 600, and the second layer rack 520 is used to place the right luggage rack 700.

[0056] The storage rack 500 is divided into the first layer rack 510 and the second layer rack 520, respectively used to store the left luggage rack 600 and the right luggage rack 700 after polishing, so that the left luggage rack 600 and the right luggage rack 700 are classified, facilitating the subsequent process, and avoiding the confusion of the left luggage rack 600 and the right luggage rack 700.

[0057] Further, the two turntables 100 are located on the same side of the machine arm assembly 200, and the two turntables 100 and the polishing machine 400 are respectively located on the opposite sides of the machine arm assembly 200.

[0058] The specific implementation steps and principles of the embodiment are as follows: first, the turntable 100 rotates by a certain angle, so that any luggage rack moves to the clamping station, and then the machine arm assembly 200 drives the clamping assembly 300 to clamp the luggage rack on the clamping station, after clamping, the machine arm assembly 200 drives the luggage rack clamped by the clamping assembly 300 to move to the polishing station for polishing, after polishing is completed, the machine arm assembly 200 drives the luggage rack to move to the storage rack 500, the clamping assembly 300 releases the luggage rack, and the luggage rack is placed on the corresponding first layer rack 510 or second layer rack 520, the polishing of the luggage rack is completed, and the above steps are repeated to realize automatic polishing of multiple luggage racks.

[0059] It should be noted that if one luggage rack 600 on one turntable 100 is polished at a time, and then the other turntable 100 is polished, the subsequent processing flow of the right luggage rack 700 will be delayed, affecting the processing efficiency. Therefore, the staggered polishing of the left luggage rack 600 and the right luggage rack 700 in the application, when polishing the left luggage rack 600 this time, the right luggage rack 700 will be polished next time, so that the number of left and right luggage racks 700 polished is close, and the subsequent processing efficiency of the left and right luggage racks 700 will not be affected.
