After all the upper handle parts 61 in an upper handle part jig 49 are grasped, the upper handle part jig 49 is grasped by the jig gripper 47 and moved to the unloading port 43, and placed on the unloading transmission line through the unloading port 43 until the upper handle parts 61 in the lowermost upper handle part jig 49 are used up. The loading transmission line and the unloading transmission line are started respectively to transport new upper handle part jigs 49 and transport the used upper handle part jigs 49 to the next process point to be loaded on the new upper handle part 61.

[0029] The third loading mechanism 5 includes a vibrating storage tray configured to store rubber parts 63, an identification component arranged above the vibrating storage tray, a sorting gripper connected to the identification component signal, and a rubber part transfer component arranged between the sorting gripper and the rubber part mounting component 25. The sorting gripper grabs the rubber parts 63 in the vibrating storage tray according to the identification result of the identification component and places them on the rubber part transfer component. The rubber part transfer component moves the rubber parts 63 to the rubber part mounting component 25.

[0030] The vibrating storage tray includes a storage tray and a vibration structure. The vibration structure is configured to drive the storage tray to vibrate so that the rubber parts 63 are spread on the storage tray and meet the grabbing requirements of the sorting gripper. This is a related technology and will not be described in detail here.

[0031] The recognition component includes an image acquisition module and a comparison module. The image acquisition module captures a photo of the rubber piece 63 in the storage bin. The comparison module compares the photo with a preset image of the rubber piece 63 and marks the location of the rubber piece 63 that meets the grasping requirements. The sorting gripper then grasps the marked rubber piece 63. Both the recognition component and the sorting gripper are related technologies and will not be described in detail here.

[0032] The rubber part transfer assembly is arranged between the storage tray and the rubber part installation assembly 25. The rubber part transfer assembly includes a conveying motor, a transmission screw connected to the output shaft of the conveying motor, and a rubber part fixture threadedly connected to the transmission screw. The transmission motor drives the transmission screw to rotate to drive the rubber part fixture to move between the storage tray and the rubber part installation assembly 25, so as to facilitate the transportation of the rubber parts 63 after sorting by the sorting gripper to the rubber part installation assembly 25 for assembly and use.

[0033] In addition, in order to cooperate with subsequent assembly processes, the blanking component 26 includes a blanking gripper 261 and a rotating structure.
