Description

Technical Field

[0001] The utility model relates to the technical field of COF pressing, in particular to an infrared light-transmitting alignment device for pressing COF. Background Technique

[0002] During the LCD screen COF (Chip On FPC, chip on flexible printed circuit board) Bonding (pressing) process, due to the characteristic of high light transmittance of the infrared light source, the infrared light source is formed into parallel light by a matrix. The application mainly reflects that the infrared device itself does not directly participate in the COF Bonding (pressing) process, but it plays an important role in the COF alignment Bonding (pressing) application of the LCD screen. COF Bonding (pressing) is mainly about the process of fixing a chip (such as a driving IC) on a flexible printed circuit board (FPC) and making an electrical connection with the LCD screen.

[0003] The existing hot pressing alignment vision mechanism has no effect on FPC lines with low light transmittance, as the light cannot penetrate and the image is basically unclear after the camera imaging; the thickness of the quartz glass is about 4 mm, and the light transmittance will be insufficient when the light source is obliquely incident; the existing process requires removing the polarizer on the LCD first, then performing COF Bonding, and then attaching the polarizer. Problem points: high screen breakage rate, low efficiency, and increased process loss; in order to solve the above technical problems, we propose an infrared light-transmitting alignment device for pressing COF. Content of the Utility Model

[0004] The purpose of the utility model is to provide an infrared light-transmitting alignment device for pressing COF to solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an infrared light-transmitting alignment device for pressing COF, including a fixing plate and a bracket. A linear guide rail is installed at the bottom end of the fixing plate. A slider cooperating with the linear guide rail is installed at one end of the bracket. An infrared parallel light source is installed at the other end of the bracket. The bracket is of an L-shaped structure.

[0006] Preferably, a limit block for limiting the slider is installed on one side of the fixing plate.

[0007] Preferably, the bracket includes a vertical plate, a reinforcing plate, and a horizontal plate. The vertical plate and the horizontal plate are perpendicularly arranged and are connected by bolts between the vertical plate and the horizontal plate. A reinforcing plate is installed at the connection of the vertical plate and the horizontal plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. It can meet the alignment of glass (including polarizer). After the FPC line is placed, the lines of the FPC line body and the glass circuit can still be clearly seen, realizing accurate alignment of both sides.
