Detailed Description
The invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1 and 2, a method for manufacturing a PET adhesive film sheet for FPC products may include the steps of:
s1, feeding, namely, placing the PET mucosa roll 100 on a feeding roller 1, and unfolding and tensioning the PET mucosa roll through a tensioning transmission mechanism 2. The PET film can move forward under the action of the tension transmission mechanism 2. The structure of the tensioning drive 2 is well known and will not be described here. The tensioning gear 2 is provided with an encoder to detect the distance of movement of the PET mucosa.
S2, loading a preset punching program according to the PET film sticking specification required by the FPC product. The preset punching program comprises the length of the PET film sticking sheet 200, the position coordinates of the positioning holes and the pin holes 201, and a punching route. The punching paths may be in the same direction row by row (as shown in fig. 3) or column by column (i.e., adjacent rows or columns move in the same direction) or in an S-shaped row by row (as shown in fig. 4) or column by column (i.e., adjacent rows or columns move in opposite directions). Preferably, an S-shaped line-by-line mode is adopted, so that the moving time can be saved, and the punching efficiency is improved.
And S3, automatically punching, namely punching required positioning holes and pin holes on the unfolded PET adhesive film through the punching mechanism 3 according to a preset punching program, wherein the hole diameters of the positioning holes and the pin holes are the same. The punching mechanism 3 may include a two-dimensional motion module 31, a punching cylinder 32, and a punch 33. The punching cylinder 32 is fixed on the two-dimensional movement module 31, and the punch 33 is connected with the telescopic rod of the punching cylinder 32. The two-dimensional motion module 31 may be pneumatic or electric. Therefore, the punch 33 can be moved forward, backward, leftward, and rightward to the punching position according to the punching route by the two-dimensional movement module 31. Specifically, the automatic punching includes the following processes:
s31, stopping when the PET mucosa reaches a punching station;
s32, moving the punch to a first punching position by the two-dimensional motion module 31 of the punching mechanism 3;
s33, a punch cylinder 32 of the punching mechanism 3 acts to drive a punch 33 to move downwards to complete punching of a first hole;
s34, punching other holes according to the punching route;
s35, after all holes are punched, the two-dimensional movement module 31 of the punching mechanism 3 brings the punch 33 back to the initial position, and the PET adhesive film moves forwards by the length of one PET adhesive film sheet so as to punch the next PET adhesive film sheet.
And S4, automatic cutting, namely cutting the punched PET adhesive film into PET adhesive film pieces with preset lengths through a cutting mechanism 4, and dropping the cut PET adhesive film pieces into a material receiving box 5. Specifically, the cutting mechanism 4 comprises a cutting cylinder and a blade, when the punched PET mucosa moves to a cutting station, the cutting cylinder drives the blade to cut the PET mucosa downwards to obtain a PET mucosa sheet, and the PET mucosa sheet falls into the material receiving box 5.
Further, the method may further comprise the steps of: the punch 33 is replaced according to the pilot hole and pin hole specifications, which is generally completed before the feeding step S1. It should be understood that this step may be completed before the automatic punching step S3.
