Description

Technical Field

[0001] The utility model relates to the field of light guide plate processing, in particular to a light guide plate positioning carrier. Background Art

[0002] The light guide plate is usually made by injection molding acrylic or PC material into a plate shape, and then printing light guide points on the bottom of the plate using high-tech materials with extremely high refractive index and non-light absorption.

[0003] After the plate for the light guide plate is injection molded, a long strip of sprues is formed on its surface. After molding, the sprues on the surface need to be sheared off to make a plate for the light guide plate of corresponding size.

[0004] At present, the nozzles on the light guide plate are mainly cut off manually. The operator cuts the light guide plate with a hook knife. When cutting, the processing size must be planned first, and then the hook knife is used to cut to half of the thickness of the plate, and finally it is broken manually; however, this cutting method has poor incision smoothness and is prone to burrs and jaggedness. In order to improve the smoothness of the incision, the cut light guide plate is currently fixed on a light guide plate fixture, and the incision of the light guide plate is milled by a milling machine. During processing, the light guide plate fixture is driven to move by a linear module set at its bottom, so that the incision of the light guide plate passes through the milling machine to achieve milling of the light guide plate incision.

[0005] However, the existing light guide plate fixture used to fix the light guide plate during the milling process of the light guide plate cutout is usually fixed in position. After the light guide plate is placed on the light guide plate fixture, the cutout side that needs to be shaped extends outside the fixture, and the other three sides are limited by the positioning blocks fixed on the light guide plate fixture. The light guide plate is placed in the shape enclosed by the positioning blocks. This light guide plate fixture is convenient for taking and placing the light guide plate, but it cannot be universal for light guide plates of different shapes and sizes. The installation position of the positioning blocks needs to be changed for applicability. Therefore, the universality of the light guide plate fixture is not strong. Summary of the invention

After that, the vacuum generator draws air through the pipeline connected to the air source interface 311, and a negative pressure is generated in the air cavity 321 through the air source interface 311, so that the air holes 331 on the panel 33 generate a certain suction force, and the light guide plate 7 on the panel 33 is adsorbed and fixed on the panel 33; the linear module 5 drives the top plate 2 to move forward to the set position, and the bottom plate 1 is driven laterally by the linear module 5 installed laterally at its bottom to realize lateral movement (the method of setting a lateral linear module at the bottom of the bottom plate 1 to drive its lateral movement is a conventional operation, which is not described in detail here), realizing the overall movement of the light guide plate positioning carrier, so that the front cutout of the light guide plate 7 on the panel 33 passes through the milling mechanism, and the milling processing of the front cutout of the light guide plate 7 is realized.

[0036] This light guide plate positioning carrier can adjust the front and rear longitudinal position of the light guide plate adsorbed on the adsorption carrier through a top plate that can move forward and backward. The accuracy of the position of the light guide plate placed on the adsorption carrier in the left and right length directions can be guaranteed through multiple sets of digital micrometer heads, thereby ensuring the position accuracy of the light guide plate on the adsorption carrier. The adsorption carrier can adapt to the placement of light guide plates of different sizes by adsorbing and fixing the light guide plate in conjunction with a linear module, and has strong versatility.
