Technical Field

[0001] The utility model relates to the technical field of light guide plate processing, in particular to a liquid leakage prevention mechanism for light guide plate processing. Background Art

[0002] A light guide plate is usually used in optical devices to control and guide the propagation direction of light. It is usually made of a transparent material, such as plexiglass, and usually has a flat surface texture, and will be polished and processed according to specific needs.

[0003] During the processing, a cleaning liquid is used to clean the processing surface to wash away dust-like foreign matters. However, during the processing, in the processing chamber of the glued and spliced light guide plate, due to the problem that the cleaning liquid penetrates into the light guide plate, the use of the light guide plate will be affected. For this reason, we propose a liquid leakage prevention mechanism for light guide plate processing to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to propose a liquid leakage prevention mechanism for light guide plate processing aiming at the problems existing in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A liquid leakage prevention mechanism for light guide plate processing, including an installation table, a rotating disk and a support cylinder. The installation table is arranged at the upper end of the support cylinder. The rotating disk is rotatably installed inside the support cylinder. The upper end of the installation table is provided with clamping plates distributed in a rectangular array. Symmetrically distributed sliders are arranged at the lower ends of the clamping plates. The upper part of the rotating disk is provided with connecting plates distributed in a rectangular array. A travel rod is arranged at the lower end of the connecting plate. Adjustment grooves distributed in an annular array are formed inside the rotating disk. The travel rod is slidably installed inside the adjustment groove. A rotating shaft is arranged at the lower end of the rotating disk. A worm gear is sleeved on the outer wall of the rotating shaft. A motor is arranged inside one end of the support cylinder. One end of the motor is provided with a worm that meshes with the worm gear.

[0006] Preferably, one end of the worm is rotatably installed inside the support cylinder, and the output end of the motor is rotatably installed with the support cylinder. Both the worm and the output end of the motor are rotationally supported.

[0007] Preferably, the lower end of the support cylinder is in an open shape. The open shape of the lower end of the support cylinder is convenient for the installation and maintenance of the internal structure.

[0008] Preferably, a bearing seat is arranged inside the lower end of the support cylinder, and the lower end of the rotating shaft is rotatably installed inside the bearing seat. The rotating shaft is rotationally supported by the bearing seat.

[0009] Preferably, annularly arrayed support rods are arranged on the outer wall of the bearing seat, and the outer walls of the support rods are connected to the inner wall of the support cylinder. The bearing seat is fixed inside the support cylinder through the support rods.

[0010] Preferably, a chute is provided inside the upper end of the mounting table and is distributed in a rectangular array. The slider is slidably mounted inside the chute, and the lower end of the slider is connected to the connecting plate. The clamping plate slides through the slider inside the chute to slide and guide the stroke plate.

[0011] Preferably, rubber pads are provided at opposite ends of the clamping plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model is provided with clamping plates of the same specification to clamp the four sides of the light guide plate. During the clamping process, through the driving force of the worm on the worm gear, the rotating disk is driven to squeeze the stroke rod, so as to realize synchronous adjustment of the clamping plates distributed on the four sides to move synchronously, effectively clamp the light guide plate with equal specifications on the four sides, cover the splicing surface, and prevent the cleaning liquid during processing from contacting the side of the light guide plate, achieving an effective anti-leakage effect and ensuring the quality of the light guide plate after processing.
