Problems solved by technology

At present, manual tearing of the film is generally used. When the film is torn manually, firstly, the external variable factors interfere greatly, the stability and quality of the product cannot be effectively guaranteed, and the management is difficult; secondly, the labor intensity of the workers is high, and the production cost is high.

Embodiment 1

[0023] A film-tearing method for a film board in PCB production, which includes a film board transmission mechanism for conveying a film board, an adhesive tape coated with a layer of adhesive on the surface, an adhesive tape winding mechanism, and a sticking mechanism; the film board is in the process of conveying , The PET protective film on the film-attaching board is stuck up by the adhesive tape through the sticking mechanism and the PET protective film is separated from the film-attaching board. At the same time, the adhesive tape with the PET protective film is rolled up.

[0024] In order to ensure that the adhesive tape sticks to the PET protective film, the conveying speed of the film sticking board in the present invention is 2m / min˜5m / min.

[0025] In order to ensure that the adhesive tape sticks to the PET protective film, the conveying speed of the film sticking board in the present invention is preferably 3m / min˜4m / min.

[0026] The conveying speed of the film s...

Embodiment 2

[0038] Depend on Figure 4 It can be seen that, in order to remove the PET protective film 13 on both sides of the film-sticking board 1 at the same time, the adhesive tape winding mechanism of the present invention is divided into two groups, which are respectively arranged on the two sides of the film-sticking board 1. 9; The tape 5 on each group of tape wheels 2 is wound on the corresponding film-receiving rubber wheel 8 through the corresponding film-removing rubber wheel 9, and the pressure between the two film-removing rubber wheels 9 is 1㎏ / ㎝ 2 ~4㎏ / ㎝ 2 (This example is 2㎏ / ㎝ 2 ); during the transmission process of the sticking plate 1 to the sticking mechanism, the PET protective film 13 on the sticking plate 1 that is in contact with the adhesive surface of the sticking tape 5 is respectively stuck up by 2 peeling rubber wheels 9 with the tape 5 wrapped around it. The PET protective film 13 is separated from the film sticking board 1 , and at the same time, each film-r...

Abstract

The invention discloses a mechanical automatic film tearing method of a film pasting plate in printed circuit board (PCB) production, the mechanical automatic film tearing method is characterized in that: in the process of transmission of the film pasting plate, a PET (polyethylene glycol terephthalate) protective film is pasted by an adhesive tape, the PET protective film is separated from the film pasting plate, and the adhesive tape stuck with the PET protective film is rolled; a film tearing device comprises a frame, an adhesive tape rolling mechanism and a sticking mechanism; a film pasting plate delivery mechanism comprising a driving wheel is arranged on the frame, the adhesive tape rolling mechanism comprises the adhesive tape, an adhesive tape wheel and a film collecting adhesive wheel, the sticking mechanism comprises a film uncovering rubber wheel, the adhesive tape on the adhesive tape wheel is winded on the film collecting adhesive wheel by the film uncovering rubber wheel, in the process of transmission of the film pasting plate, the PET protective film on the film pasting plate is stuck up by the film uncovering rubber wheel for separation of the PET protective film and the film pasting plate, at the same time, the adhesive tape stuck with the PET protective film is rolled by the film collecting adhesive wheel, the method is simple, the automation of artificial film tearing is realized, the production efficiency and product stability can be improved, artificial operation factors can be eliminated, product quality can be better controlled, the labor intensity of workers can be reduced, and the production cost can be reduced.

Description

technical field [0001] The present invention relates to a kind of treatment of the PET protective film of the laminated board in the production of printed circuit board (PCB), specifically a kind of film tearing method and film tearing device of the PET protective film, especially relates to a kind of adopting mechanical automatic way to Film tearing method and film tearing device for laminated boards in PCB production. Background technique [0002] The graphics transfer process in the production of printed circuit boards (PCBs) mainly includes the steps of pre-processing grinding board-pressing dry film-exposure-development, etc. The PET protective film on the film-attached board must be removed after exposure and before development. At present, manual tearing of the film is generally used. When tearing the film manually, firstly, the external variable factors interfere greatly, the stability and quality of the product cannot be effectively guaranteed, and the management is...
