Description

Technical Field

[0001] The utility model patent relates to the technical field of cutting devices, and mainly relates to a universal device for cutting off silicone glue of screen terminals. Background Art

[0002] The LCM screen is composed of multiple layers of thin plate workpieces with different functions, forming a functional screen that embodies modern technology. LCM products generally have a TFT screen. The internal design of the TFT is a circuit to control the display of the screen image. The terminals of the TFT circuit pins are concentrated at the bottom of the screen. In order to protect the terminal area, prevent damage to the terminal area and insulate the terminal area, it is usually necessary to apply silicone glue to the terminal area at the bottom of the screen, and then bond it with other functional screens. However, the bonding process may cause the bonding effect to be unsatisfactory due to some factors. In order to save costs and reduce the scrap rate, the defective products after bonding will be collected and repaired. During the repair, the silicone glue needs to be cut off, and then the two bonded screens are separated, and then the bonding process is repeated;

[0003] However, the existing process of cutting silicone glue is a manual operation, which requires inserting a blade into the gap between the two bonded screens to cut the silicone glue without damaging or scratching the screen. However, in manual operation, in order to protect the product, the glue cutting process consumes a lot of time, and manual errors may occur, resulting in scratches on the screen. In this regard, we propose a universal device for cutting silicone glue on screen terminals. Utility Model Content
