At this time, the hanger unloading robot 6 releases the hanger material tray 9, and the upper and lower driving modules 011 drive the fixed frame 012 to move downward, and move the hanger material tray 9 to the placement plate 013, and then continue to drive the fixed frame 012 to move upward.

[0033] In this embodiment, in order to cooperate with the position of the hanger loading mechanism 1, the workpiece loading mechanism 3 and the hanger unloading mechanism 5, four workstations are provided on the workstation turntable 7 to facilitate rotating the workstation to the corresponding mechanism for operation. A hanger positioning device 71 is provided on the workstation, and the hanger positioning device 71 includes a positioning cylinder assembly 711 and a hanger placement plate 712. The positioning cylinder assembly 711 includes symmetrically arranged upper and lower drive cylinders 7111, left and right drive cylinders 7112 and clamping block cylinders 7113. The hanger placement plate 712 is fixed to the upper and lower driving cylinders 7111 through a connecting plate, the left and right driving cylinders 7112 are connected to the driving ends of the upper and lower driving cylinders 7111, the clamping block cylinder 7113 is connected to the driving ends of the left and right driving cylinders 7112, and both ends of the hanger placement plate 712 are connected to the clamping block cylinder 7113. The clamping block cylinder 7113 is provided with a clamping block 7114 which can move toward or oppositely, and the clamping block 7114 is respectively located on both sides of the two ends of the hanger placement plate 712. During operation, the hanger loading robot 2 places the hanger 11 on the hanger placing plate 712. At this time, the clamping block cylinder 7113 drives the clamping block 7114 to move towards each other, clamping the two ends of the hanger 11 respectively, and then the left and right driving cylinders 7112 at both ends also move in opposite directions, pulling the two ends of the hanger 11 outward, and the upper and lower driving cylinders 7111 move downward, so that there are downward and outward pulling forces at both ends of the hanger 11, ensuring that the hanger 11 operates in a straightened state; when the work station turntable 7 is rotated to one side of the hanger unloading mechanism 5, all cylinders of the positioning cylinder assembly 711 return to their original state. At this time, the clamping block 7114 of the clamping block cylinder 7113 has loosened the two ends of the hanger 11, making it convenient for the hanger unloading robot 6 to clamp the hanger 11 and place it on the hanger material tray 8 above the material tray receiving table 8.

[0034] The automatic lens electroplating mounting machine of this embodiment further includes a controller for controlling various mechanisms and a rack for fixing various mechanisms and devices. Since the controller and the rack belong to the prior art, they will not be described in detail here.

[0035] The working process of the automatic hanging machine for electroplating lens pieces in this embodiment is as follows: first, the hanger loading robot 2 takes out the hanger 11 from the hanger material tray 9 on the hanger loading mechanism 1 and places it on the hanger positioning device 71 of the corresponding station of the station turntable 7, and the hanger positioning device 71 drives the positioning cylinder assembly 711 to clamp the two ends of the hanger 11 and pull the hanger 11 downward and outward; then the station turntable 7 is driven by the motor to rotate to the bottom of the movable plate 351 of the pulling device 35, and the motion module 352 drives the movable plate 351 to move downward, and then drives the movable plate 351 to move toward each other, so that the card slot 3512 in the positioning slot 3511 of the movable plate 351 squeezes the elastic sheet 112 of the elastic claw 111; at the same time, the lens piece loading robot 32 sucks the workpiece material tray 10 through the workpiece material tray suction cup 326 and places it on the workpiece material tray platform 33, Then, the lens piece loading robot 32 sucks the lens piece through the workpiece suction cup 327 and places it on the workpiece position 341 of the lens piece distance changing device 341. After the lens piece distance changing module adjusts the distance of the workpiece position 341, the workpiece loading robot 4 sucks the lens piece from the lens piece distance changing device 341 and places it on the four raised points 114 corresponding to the elastic claws 111 on the hanger 11. Then the motion module 352 drives the movable plate 351 to move in the opposite direction and move upward. At this time, the positioning groove 3511 of the movable plate 351 releases the squeeze on the elastic claw 111, so that the raised point 113 of the elastic claw 111 elastically clamps the lens piece; finally, the work station turntable 7 is driven by the motor to rotate to the side of the hanger unloading mechanism 5, and the hanger unloading robot 6 clamps the hanger 11 full of lens pieces and places it on the hanger material tray 9 above the material tray receiving table 8. Among them, when the hanger material tray 9 on the hanger loading mechanism 1 is emptied, the hanger loading robot 2 takes out the empty hanger material tray 9 of the hanger loading mechanism 1 and places it on the material tray receiving platform 8. When the hanger material tray 9 on the material tray receiving platform 8 is full, the hanger unloading robot 6 places the hanger material tray 9 filled with hangers 11 on the hanger unloading mechanism 5. The above is the hanging operation process;

[0036] In addition, since the hanger unloading mechanism 5 has the same structure as the hanger loading mechanism 1, the automatic hanging machine of this embodiment can also realize the hanging operation. When performing the hanging operation, it is only necessary to perform the operation process in the opposite order of the hanging operation.
