Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0025] In the prior art, manually tearing off the film coating on the surface of the light guide plate of the LED lamp is costly and inefficient, and it is easy to introduce dust pollution and scratch the light guide plate. In the field of liquid crystal display production, there is also the problem of tearing off the surface film of optical board devices. Adhesive rollers are often used to paste the tear film. This kind of film tearing device needs to replace the adhesive roller regularly, which reduces the efficiency of tearing the film and increases the cost of tearing the film. This sticky roller film tearing device needs to be adjusted and modified according to different film sizes, and the versatility of the device is low.

[0026] The invention proposes a film tearing device for a light guide plate of an LED lamp. The film tearing device for...

Abstract

The invention relates to a light guide plate film tearing device of an LED (light-emitting diode) lamp, and belongs to the fields of production and manufacturing of LED lamps. According to the light guide plate film tearing device of the LED lamp, an adhesive tape adhered with a coating film on a light guide plate surface layer of the LED lamp is moved by a mechanical arm, the coating film on the light guide plate surface layer of the LED lamp is torn, the adhesion surface of the adhesive tape realizes continuous updating of the adhesion surface of the adhesive tape through a PLC (Programmable Logic Controller) and a corresponding winding device, continuous tearing of the coating film on the light guide plate surface layer film of the LED lamp is realized, the adhesive tape is not need to be changed frequently, and repeated use of the adhesion surface of the adhesive tape is realized. The device realizes the application of appropriate pressure for the adhesive tape through a cylinder and a briquetting spring, tight contact between the adhesive tape and the coating film on the light guide plate surface layer of the LED lamp can be guaranteed, and a light guide plate is prevented from being scratched by excessive pressure or non-uniform force application; the device is small in size, and various sizes of coating films on the light guide plate surface layer of the LED lamp can be torn under the driving of the mechanical arm.

Description

technical field [0001] The invention relates to a film tearing device, in particular to a film tearing device for a light guide plate of an LED lamp. Background technique [0002] As a point light source, the light intensity distribution of LED is not uniform. In daily life and production, it is necessary to convert the light guide plate into a planar light source to improve the softness of the LED light source. In order to effectively convert LED light, it is necessary to keep the surface of the light guide plate clean. In the prior art, the method of covering the light guide plate is used to protect the light guide plate, and the surface film of the light guide plate is manually torn off during the subsequent installation process of the light guide plate. Manually tearing off the surface coating of the LED light guide plate is costly and inefficient, and it is easy to introduce dust pollution and scratch the light guide plate. [0003] In the field of liquid crystal disp...
