Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reinforcing sheet attaching, and particularly relates to a FPC reinforcing sheet machine attaching method. BACKGROUND

[0002] FPC soft board is relatively flexible in the application process, and can be better set in some special-shaped spaces according to its own properties, thereby improving the convenience of circuit setting. However, the soft property of the FPC soft board also has certain structural deficiencies, and therefore some reinforcing structures need to be set to improve the strength of the FPC soft board.

[0003] When the back adhesive reinforcing sheet is attached on the FPC soft board, it is required to use the micro-adhesive film to carry the reinforcing sheet roll to realize automatic machine attaching. However, for some super-small size reinforcing sheets, the size of the machine attaching suction nozzle is limited and cannot be directly machine attached. Generally, the reinforcing sheet is made into SHHTE shape, and then the reinforcing sheet jig is attached by manual alignment, which has the problems of low production efficiency and high product failure rate.

[0004] Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems in the prior art. SUMMARY

[0005] In order to overcome at least one of the above-mentioned defects, the present application provides a FPC reinforcing sheet machine attaching method, which increases a protective film with a size larger than the attached reinforcing sheet on the non-adhesive surface of the reinforcing sheet, so as to realize automatic attaching by the suction nozzle of the automatic attaching machine.

[0006] In order to achieve the above-mentioned purpose, the process disclosed in the present application can adopt the technical solution proposed as follows:

[0007] A FPC reinforcing sheet machine attaching method comprises the following steps:

[0008] Arraying the reinforcing sheet protective film on the initial carrier sheet, so that the non-adhesive surface of the reinforcing sheet protective film is attached to the carrier sheet, and covering the adhesive surface of the reinforcing sheet protective film with a removable surface layer;

[0009] Setting the back adhesive on the reinforcing sheet;

[0010] Setting a plurality of profiling grooves for positioning the reinforcing sheet on the reinforcing sheet jig, and the profiling grooves correspond one-to-one to the reinforcing sheet protective film;

[0011] Correspondingly setting the reinforcing sheet in the profiling grooves, so that the reinforcing sheet is exposed on the surface of the reinforcing sheet jig;

[0012] Removing the surface layer and positioning the initial carrier sheet on the reinforcing sheet jig, so that the reinforcing sheet protective film is attached one-to-one to the reinforcing sheet;

[0013] Performing transfer and winding.

[0014] The FPC reinforcing sheet pasting method disclosed above can suck and transfer the initial carrier sheet through the suction nozzle, thereby transferring the reinforcing sheet protection film on the initial carrier sheet, and realizing the pasting of multiple reinforcing sheets and reinforcing sheet protection films at one time through pasting. The problem that the reinforcing sheet cannot be quickly pasted and aligned by the suction nozzle in the prior art can be solved, and the problems of poor alignment accuracy and low pasting quality caused by manual pasting can also be avoided.

[0015] Further, in order to stably arrange the reinforcing sheet protection film on the initial carrier sheet and realize subsequent removal of the initial carrier sheet, the initial carrier sheet and the reinforcing sheet protection film can be connected and arranged in various ways, such as point gluing and pasting in some schemes, and release film pasting in some schemes. In the present application, one feasible option is optimized and presented as follows: the pasting surface of the initial carrier sheet and the reinforcing sheet protection film is an adhesive surface, the adhesive surface of the initial carrier sheet is a micro-adhesive surface, and the reinforcing sheet protection film is arranged in a row-column form on the initial carrier sheet. When this scheme is adopted, a micro-adhesive film can be used as the initial carrier sheet to realize the connection between the initial carrier sheet and the reinforcing sheet protection film, and the initial carrier sheet and the reinforcing sheet protection film can be separated subsequently.

[0016] Further, in order to achieve the reinforcing effect and ensure long-term stability without affecting the work of the FPC soft board due to oxidation and deformation, the present application optimizes the reinforcing sheet and presents one feasible option as follows: the reinforcing sheet is made of stainless steel material.

[0017] Further, when the reinforcing sheet is pasted, the reinforcing sheet should be located at a predetermined position to realize one-to-one correspondence with the reinforcing sheet protection film. To achieve this effect, various feasible options can be used, and the present application optimizes and uses a profiling groove to achieve this effect: the back adhesive is pasted on the back surface of the reinforcing sheet, and the size of the back adhesive is smaller than the size of the reinforcing sheet. The back adhesive is provided with a recess structure, and the reinforcing sheet is provided with a through hole corresponding to the recess structure. When this scheme is adopted, the size of the back adhesive is smaller than the size of the reinforcing sheet, and the profiling groove is arranged according to the size of the reinforcing sheet. After the reinforcing sheet is placed in the profiling groove, the reinforcing sheet can be placed on the surface of the reinforcing sheet jig, and good contact and pasting can be realized when the surface layer is pasted. The back adhesive and the profiling groove are not bonded, and the back adhesive can be taken out of the profiling groove by taking the surface layer subsequently.

[0018] Further, the structure of the reinforcing sheet can be configured in various forms, which can play the role of fitting the FPC soft board to improve the strength, for example, in some schemes, an oval shape, a polygonal shape, or a shape combining an arc edge and a straight edge can be used, and the application is optimized and one of the feasible options is given: the reinforcing sheet includes a circular sheet, and the adhesive includes a circular ring-shaped adhesive and is concentrically attached to the circular sheet. When such a scheme is used, the supporting force of the circular sheet is more balanced and stable, and the edge will not scratch the FPC soft board, thereby improving the protection level of the FPC soft board.

[0019] Further, in the application, the reinforcing sheet jig is used as a bearing component for bearing the reinforcing sheet and positioning the initial bearing sheet during the sleeving process, and one of the feasible options is given here: the reinforcing sheet jig and the initial bearing sheet are aligned through the corresponding positioning structure, and the positioning structure includes a positioning column and a positioning hole that are correspondingly matched, or a positioning block and a positioning groove that are correspondingly arranged. When such a scheme is used, the positioning column can be arranged on the reinforcing sheet jig, the positioning hole can be arranged on the initial bearing sheet, or the positioning block can be arranged on the reinforcing sheet jig, and the positioning groove can be arranged on the initial bearing sheet. In this way, the initial bearing sheet can be aligned on the reinforcing sheet jig.

[0020] Further, in order to avoid the initial bearing sheet and the reinforcing sheet jig from being installed in reverse or upside down, the positioning structure is arranged along the two opposite edges of the reinforcing sheet jig and the initial bearing sheet, and the positioning structure is staggered on the two opposite edges for alignment and fitting guidance. When such a scheme is used, different numbers of positioning columns or positioning blocks can be arranged on the two opposite edges of the reinforcing sheet jig, and positioning holes or positioning grooves can be correspondingly arranged on the initial bearing film. In this way, the fitting can only be performed in one direction, thereby avoiding reverse or upside-down installation.

[0021] Further, in the application, a transfer and winding device is arranged to store the attached reinforcing sheets, and one of the feasible options is given here: during the transfer and winding process, the initial bearing sheet on the surface of the reinforcing sheet protective film is removed, a winding bearing sheet is arranged on the surface of the adhesive, and an isolation layer is arranged on the surface of the reinforcing sheet protective film for winding. When such a scheme is used, the adhesive of the reinforcing sheet is attached to the winding bearing sheet, and the surface of the reinforcing sheet is attached to the isolation film, thereby changing the attachment direction of the reinforcing sheet and the adhesive and improving the reliability of the reinforcing sheet during winding.

[0022] Further, in the application, the isolation layer can be made of various materials, and one of the feasible options is given here: the isolation layer is made of an isolation film.

[0023] Further, in the present application, the surface layer can be made of various materials, and specifically, one possible selection is that the surface layer is an isolation layer.

[0024] Compared with the prior art, some beneficial effects of the technical scheme of the present application include:

[0025] The present application realizes high-efficiency automatic machine pasting through the suction nozzle by setting multiple reinforcing sheet protection films on the initial bearing sheet and aligning and pasting the multiple reinforcing sheets on the reinforcing sheet fixture, and the machine pasting alignment can avoid the error of manual alignment, thereby improving the reliability of pasting.
