Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, in particular to a PCB board laminating mechanism. Background Art

[0002] PCB is one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuits for electrical interconnection between them. Therefore, PCB is widely used. In the manufacturing process of PCB, several processes are required, such as lamination, screen printing, etching, shooting, baking, and cleaning.

[0003] 1. In the prior art, the existing PCB board laminating machine includes a pressure roller, which coats a film on the surface of the PCB board through the pressure roller. However, the film coated in this way is prone to leaving bubbles between the film and the PCB board, and the film is not firmly coated and is easy to fall off.

[0004] 2. In the prior art, when a traditional PCB laminating machine is laminating a PCB board, the PCB board is easily contaminated with dust during transportation, and it is difficult for an ordinary fan to completely remove the dust, causing the film to easily fall off. Utility Model Content

[0005] The utility model provides a PCB board laminating mechanism to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

In addition, the rubber roller has greater elasticity, which can enhance the tension resistance of the film, making it less likely for the film to break or wrinkle during operation.

[0010] A further improvement of the technical solution of the utility model is that: the cutter device is installed at the leftmost side of the threaded rod, and the blade on the cutter device is installed in the middle of the cutter device.

[0011] By adopting the above technical solution, the use of the cutter device and the threaded rod in the solution can greatly improve the safety of the cutter device operator by installing the cutter device on the leftmost side of the threaded rod and making the blade on the cutter device not only small in size but also installed in the center of the cutter device.

[0012] A further improvement of the technical solution of the utility model is that the loading roller and the feeding roller are both installed on the top of the base, and the height of the loading roller is greater than that of the feeding roller.

[0013] By adopting the above technical solution, the use of the loading roller and the feeding roller in the solution can make the height of the feeding roller lower than the loading roller at the base, so that the film can be tightened and it is not easy to wrinkle during the lamination process.

[0014] A further improvement of the technical solution of the utility model is that: two groups of fans are provided, and the two groups of fans are arranged in a matrix on the top of the operating table.

[0017] The above technical solution is adopted. The scouring pad and the operating table in the solution are used. The scouring pad has a strong decontamination effect. When wiping the PCB board, it can strongly remove dirt without leaving any marks. At the same time, the scouring pad has been antibacterial processed and has an antibacterial effect.

[0018] A further improvement of the technical solution of the utility model is that four groups of second support columns are installed at the bottom of the bracket, and the four groups of second support columns are installed on the four corners of the operating table.

[0019] The above technical solution is adopted, in which the bracket, the second support column and the operating table are used.
