[0041] In this embodiment: The conveyor line 61 located on the feeding side of the frame 1 conveys the rubber parts to the baffle. The cylinder gripper 24 drives the clamping claw 2403 through the extension frame 2401 to clamp the rubber parts. At this time, the deflection motor 2 drives the rotary cylinder 23 and the cylinder gripper 24 to deflect through the mounting shaft 21 and the mounting frame 22. During the deflection process, the rotary cylinder 23 needs to perform a 90° deflection treatment on the cylinder gripper 24 to send the rubber parts with a cylindrical shape on the clamping claw 2403 outside the main clamping seat 3201.

[0042] The clamping cylinder 33 cooperates with the support frame 3301 to drive the auxiliary clamping seat 3302 to move. The auxiliary clamping seat 3302 cooperates with the main clamping seat 3201 to clamp the rubber parts.

[0044] For the rubber parts that have completed the silk transfer printing process, the first linear module 3 and the first slide 31 need to cooperate to reduce the working height adjustment of the main clamping seat 3201 and the auxiliary clamping seat 3302. The deflection motor 2 located on the discharging side of the frame 1 drives the rotary cylinder 23 and the cylinder gripper 24 to deflect through the mounting shaft 21 and the mounting frame 22. After the cylinder gripper 24 cooperates with the extension frame 2401 to drive the clamping claw 2403 to complete the grasping process of the rubber parts, the deflection motor 2 continues to work to adjust the cylinder gripper 24 to the conveyor line 61 device on the discharging side of the frame 1.
