Abstract

This utility model discloses a robotic gripper fixture for producing irregularly shaped and round-hole light guide plates. It includes a main board with several suction cup post fixing aluminum plate mounting slots. The suction cup post fixing aluminum plates are installed in the mounting slots and have first, second, third, and fourth U-shaped grooves. Several suction cup posts are provided and respectively installed in the first, second, third, and fourth U-shaped grooves, with a suction cup mounted at one end. A pneumatic clamp provides negative pressure to each suction cup. Adjustable teeth are provided on the main board at each suction cup post fixing aluminum plate mounting slot. This robotic gripper fixture for producing irregularly shaped and round-hole light guide plates allows for adjustment of the suction cup posts' height, position, and orientation, ensuring stable adsorption and smooth removal of the light guide plate, and offering high versatility.
