Description

Technical Field

[0001] The utility model belongs to the technical field of backlight module pressing, and particularly relates to a lamp glue pressing fixture. Background Art

[0002] The light guide plate is made of optical-grade acrylic / PC plates, and then a high-tech material with extremely high refractive index and non-light-absorbing property is used to print light guide points on the bottom surface of the optical-grade acrylic plate by laser engraving, V-shaped cross-grid engraving, and UV screen printing technologies. The optical-grade acrylic plate is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will diffuse in all directions, and then the reflection condition is destroyed and the light is emitted from the front of the light guide plate. Through various light guide points with different densities and sizes, the light guide plate can emit light evenly. It can be seen that the light guide plate is a product that converts a line light source into a surface light source, and usually needs to be closely pressed and used with a light guide lamp strip.

[0003] Due to various usage requirements, the top surface of the light guide plate often has an inclined slope. However, the bottom surface of the pressing part in the existing light guide plate pressing equipment is usually a horizontal plane. Therefore, during the process of pressing the light guide plate and the lamp strip, it cannot be completely attached to the top surface of the light guide plate, resulting in uneven force on the light guide plate, and ultimately there is a hidden danger that the pressing surface of the light guide plate and the lamp strip cannot be completely and closely fitted. Summary of the Utility Model

[0004] The utility model provides a lamp glue pressing fixture to solve the above technical problems.

[0005] The solution adopted by the utility model to achieve its technical effect is as follows:

[0006] A lamp glue pressing fixture includes a mounting frame, a lifting driving device, a lifting frame, and a pressing block; the lifting driving device is arranged on the mounting frame; the lifting frame is arranged at the bottom of the driving end of the lifting driving device; the pressing block is elastically arranged at the bottom of the lifting frame.

[0007] Preferably, it further includes a pressing driving device and a pressing frame; the pressing driving device is arranged at the top of the lifting frame; the pressing frame is arranged at the bottom of the lifting frame, and the pressing frame is arranged at the bottom of the driving end of the pressing driving device; the pressing block is elastically arranged at the bottom of the pressing frame.

[0008] Preferably, the pressing block includes a mounting block, a spring, and an adjusting block; the mounting block is arranged at the bottom of the lifting frame; a lifting groove is formed at the bottom of the mounting block; the spring is arranged in the lifting groove; the adjusting block is slidably arranged in the lifting groove, and the adjusting block is arranged at the bottom of the spring.

[0009] Preferably, a limiting baffle is arranged in the lifting groove; the adjusting block is located below the limiting baffle; the bottom of the spring passes through the limiting baffle and is arranged on the top of the adjusting block.

[0010] Preferably, the pressing block includes a mounting plate and a rubber block; the mounting plate is arranged at the bottom of the lifting frame; a mounting groove is arranged at the bottom of one side of the mounting plate; the rubber block is arranged in the mounting groove.

[0011] Preferably, positioning and mounting holes communicating with the mounting groove are arranged on the mounting plate; vertical strip holes are arranged on the rubber block; the rubber block is fixed in the mounting groove by bolts in cooperation with the mounting holes and the strip holes.

[0012] The beneficial effect of the present utility model is that the pressing block is elastically arranged at the bottom of the lifting frame. When there is an inclined slope on the top surface of the light guide plate, when pressing the pressing block downwards, a part of the bottom surface will first contact the light guide plate. At this time, when continuing to press the pressing block downwards, the contact end can be compressed upwards under the action of elastic force, so that the non-contact end tilts to one side and continues to press downwards, and finally the bottom surface of the pressing block is completely attached to the top surface of the light guide plate, thereby ensuring that the light guide plate and the lamp strip are pressed flat and seamless.
