Description

Technical Field

[0001] The utility model belongs to the technical field of light guide plate processing equipment, and particularly relates to a processing device for a circular light guide plate. Background Technique

[0002] In the prior art, through retrieval, it is found that the Chinese patent discloses "a side polishing device for a circular light guide plate", and its publication number is "CN106272062B". This patent mainly facilitates the manual polishing of the side of the circular light guide plate, improves the safety of manual polishing, and can improve the polishing efficiency.

[0003] When polishing the side of the circular light guide plate, there are some problems with the original device. The device only clamps and fixes the center point of the circular light guide plate. This method is likely to cause wrinkles in the circular light guide plate during the grinding process. This is because only fixing the center point without comprehensively supporting the entire circular light guide plate will cause it to deform and skew under the action of the polishing force, thus affecting the processing quality of the circular light guide plate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a processing device for a circular light guide plate. By providing a clamping mechanism, it is ensured that the circular light guide plate can maintain stable grinding under the covering and clamping of a plurality of rubber pads, and the problem of deformation and skew of the circular light guide plate under the action of the polishing force is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a processing device for a circular light guide plate, including a frame and two support plates. Two clamping mechanisms and an adjusting mechanism are arranged on the frame. The clamping mechanism includes a connection component and a buffer component;

[0007] The connection component includes a fixed disk fixedly connected to the left side of the corresponding support plate. A first motor is fixedly connected to the left side surface of the fixed disk. The output end of the first motor is fixedly connected to a rotating rod.

[0009] Further, springs are wound around several of the sliding rods. One end of each spring is fixedly connected to the piston, and the other end of each spring is fixedly connected to the inner wall of the connecting sleeve.

[0010] Further, the adjusting mechanism includes a driving assembly, a limiting assembly, and a grinding assembly. The driving assembly includes a second motor fixedly connected to the right end of the frame. The output end of the second motor is fixedly connected to a bidirectional threaded rod. The bidirectional threaded rod rotates through the frame, and two connecting plates are sleeved on the bidirectional threaded rod in a threaded manner.

[0011] Further, a connecting rod rotates through the frame, and the connecting rod slides through the two connecting plates.

[0012] Further, the limiting assembly includes annular grooves respectively formed on the two connecting rods. Annular rings are fixedly connected to the outer walls of the two support plates, and the two annular rings are respectively slidably connected to the inner walls of the two annular grooves.

[0013] Further, the grinding assembly includes a plurality of handles fixedly connected to the two fixed discs respectively, and a grinding table is fixedly connected to the inner bottom wall of the frame.

[0014] The utility model has the following beneficial effects:

[0015] 1.

With the cooperation of multiple arc-shaped hinge rods, multiple connecting sleeves can approach or move away from each other, enabling them to be evenly distributed on the surface of the circular light guide plate for fixing. Moreover, the connecting sleeve, piston, sliding rod, rubber cushion block, and spring cooperate with each other to buffer the clamping force, thereby preventing wrinkles caused by a single rubber cushion block during grinding after fixing, ensuring that the circular light guide plate can be stably ground under the covering and clamping of multiple rubber cushion blocks.

[0016] 2. By providing an adjusting mechanism, the second motor can be turned on to drive the bidirectional threaded rod to rotate. With the cooperation of the connecting rod, the two connecting plates can approach or move away from each other, so that the two clamping mechanisms can approach each other to clamp the circular light guide plate to adapt to the fixing of multiple or different-sized circular light guide plates. Moreover, the annular groove, annular ring, and grinding table cooperate with each other, and the multiple circular light guide plates can be rotated and ground by turning the handle, greatly improving the grinding efficiency.
