LCD liquid crystal screen cutting and packaging process

Abstract

The invention discloses a liquid crystal display (LCD) cutting and packaging process, and particularly relates to the related technical field of LCDs, and the LCD cutting and packaging process comprises the following steps: S1, stably placing a series of processed LCDs on a positioning carrier plate above the inner side of a cutting table; s2, an electric cutting machine is aligned with the starting end of the marked cutting line; and S3, continuously moving the positioning carrier plate to the position of the mounting rack, adjusting the left-right position of the spot welding machine by using a bidirectional screw rod, pasting the pasted element on the bonding pad printed with the soldering paste, and packaging and connecting the circuit board and the outer lead of the liquid crystal screen device by using a conductive adhesive. The spot welding machine is combined with the two-way lead screw, the left-right position of the spot welding machine is adjusted through the two-way lead screw, the spot welding machine can flexibly conduct lead welding on a circuit board behind an LCD screen, the worm wheel is matched with the worm, the direction of force can be changed through the worm, the worm wheel drives the worm to move up and down, and the welding precision is improved. Therefore, the height of the spot welding needle is controlled.

Description

technical field [0001] The present invention relates to the technical field related to LCD liquid crystal screens, and more specifically, the present invention relates to a cutting and packaging process of LCD liquid crystal screens. Background technique [0002] The LCD liquid crystal screen is one of the commonly used display screens in the screen, but it has certain differences from the LED screen. Display images, and LED screens use light-emitting diodes to display images. There is an essential difference between the two. The overall clarity and resolution of LCD liquid crystal screens are low, but they are often used for information playback in public places. Among them, in high-speed rail And on the subway, LCD screens are often seen. [0003] The Chinese patent application publication number CN113514970A discloses a substrate cutting and processing device for liquid crystal screens, which includes a bottom support platform for placing glass substrates. The key point...

Problems solved by technology

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an LCD liquid crystal screen cutting and packaging process to solve the problem in the above-mentioned background technology that the fixation of the screen is not stable enough in actual use, and it is easy to be damaged during the cutting process. It causes substantial damage to the screen, and it is difficult to control the cutting force of the screen, which makes the cutting of the screen prone to crack extension. The protection structure is relatively simple and the flexibility is insufficient
