[0024] The working principle of a charger appearance inspection device according to an embodiment of the present invention is described below: The workpiece is placed on the feeding and conveying assembly 11, and then the feeding and conveying assembly 11 conveys the workpiece. At this time, the first clamping module 141 and the second clamping module 142 are in the first position. Then, the first clamping module 141 of the first robotic arm assembly 14 clamps the workpiece on the feeding and conveying assembly 11. Then, the first multi-axis translation drive module 143 drives the first clamping module 141 and the second clamping module 142 to move to the second position. The first clamping module 141 places the workpiece on the first transfer table 12. The first appearance inspection mechanism 20 performs appearance inspection on the workpiece on the first transfer table 12. Then, the first multi-axis translation drive module 143 drives the first clamping module 141 and the second clamping module 142 to move to the first position. Then, the first robotic arm assembly... The first clamping module 141 of component 14 clamps the workpiece on the feeding and conveying assembly 11, and the second clamping module 142 of the first robotic arm assembly 14 clamps the workpiece on the first transfer table 12. Then, the first multi-axis translation drive module 143 drives the first clamping module 141 and the second clamping module 142 to move to the second position. The first clamping module 141 places the workpiece on the first transfer table 12, and the second clamping module 142 places the workpiece on the second transfer table 13. The first appearance inspection mechanism 20 performs appearance inspection on the workpiece on the first transfer table 12. The above steps are repeated to continuously place workpieces on the first transfer table 12 for inspection by the first appearance inspection mechanism 20, and continuously transport the inspected workpieces to the second transfer table 13.

[0025] After the second clamping module 142 places the workpiece on the second transfer table 13, the second robotic arm assembly 15 transports the workpiece to the turntable conveyor mechanism 30. Then, the turntable conveyor mechanism 30 moves the workpiece to the vicinity of the unloading mechanism 50. During this process, the second appearance inspection mechanism 40 inspects the workpiece on the turntable conveyor mechanism 30.

[0026] To facilitate the installation of the first clamping module 141 and the second clamping module 142, in some optional embodiments, the first robotic arm assembly 14 further includes a mounting frame 144, a first multi-axis translation drive module 143 is drivenly connected to the mounting frame 144, and both the first clamping module 141 and the second clamping module 142 are mounted on the mounting frame 144.

The first robotic arm assembly 14 includes a plurality of transfer clamping modules 145. The first multi-axis translation drive module 143 drives and cooperates with the transfer clamping modules 145. The first clamping modules 141, the transfer clamping modules 145 and the second clamping modules 142 move together to the first position and the second position under the drive of the first multi-axis translation drive module 143. When the transfer clamping module 145 is in the first position, the transfer clamping module 145 is located on the side of the first visual inspection module 21. When the transfer clamping module 145 is in the second position, the transfer clamping module 145 is located on the side of the second visual inspection module 22. In this embodiment, the mounting frame 144 is equipped with two first clamping modules 141, two intermediate clamping modules 145, and two second clamping modules 142. The side of the first transfer table 12 is arranged with two first vision inspection modules 21 and two second vision inspection modules 22. When the first clamping modules 141, intermediate clamping modules 145, and second clamping modules 142 are in the first position, both first clamping modules 141 are located at the feeding and conveying module, used to clamp two workpieces on the feeding and conveying module. The two intermediate clamping modules 145 are located on one side of the two first vision inspection modules 21 to facilitate clamping the workpieces inspected by the two first vision inspection modules 21. The two second clamping modules 142 are located on one side of the two second vision inspection modules 22 to facilitate clamping the workpieces inspected by the two second vision inspection modules. When the workpieces inspected by group 22 are in the second position, the first clamping module 141, the transfer clamping module 145, and the second clamping module 142 are positioned such that the two first clamping modules 141 are located on one side of the two first vision inspection modules 21, so that the workpieces can be placed on the first transfer table 12 and on one side of the first vision inspection module 21, allowing the first vision inspection module 21 to inspect the workpieces. The two transfer clamping modules 145 are located on one side of the two second vision inspection modules 22, so that the workpieces can be placed on the first transfer table 12 and on one side of the second vision inspection module 22, allowing the second vision inspection module 22 to inspect the workpieces. The two second clamping modules 142 are located on the second transfer table 13, so that the workpieces inspected by the first appearance inspection mechanism 20 can be transported to the second transfer table 13.

[0029] The above steps enable rapid transport of workpieces, allowing the first vision inspection module 21 and the second vision inspection module 22 to perform rapid inspections.

The elastic force of the elastic elements 333 drives the clamping plates 332 to press against the workpiece, thereby achieving stable clamping of the workpiece.

[0034] The specific structure of the elastic element 333 can be designed according to actual needs. For example, the elastic element 333 can be made of several springs or several sheet springs.
