Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board production, in particular to a water absorption and conveying device for improving wrinkles on FPC boards. Background Art

[0002] During the FPC board processing process, flux, solvents, or moisture may remain on the surface of the FPC board. If the water is not absorbed in time, it may affect the next process. Currently, when the FPC board passes through the horizontal sponge roller assembly, on the one hand, due to the FPC board's weak rigidity, the FPC board will bend and warp, resulting in board jams. On the other hand, due to the residual liquid on the FPC board's surface, the sponge roller assembly generates friction when contacting the FPC board, thereby slowing the FPC board's transmission speed. As a result, the transmission speed of the rear of the FPC board will be greater than the transmission speed of the front, and the FPC board will wrinkle forward, eventually causing the FPC board to be scrapped and reducing the yield rate. Utility Model Content

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a water absorption and transmission system for improving the wrinkles of FPC boards, which can reduce the card rate and effectively prevent the FPC boards from wrinkling.

[0008] Furthermore, there are at least two sponge roller groups, which are arranged one above the other and can contact the upper surface and the lower surface of the FPC board.

[0013] Furthermore, the conveying speed of the guide frame on the sponge roller assembly is lower than the conveying speed of the guide frame on the conveying device.

[0014] Furthermore, the four ends of the FPC board are attached to the lead frame by means of adhesive tapes, and at least one layer of adhesive tape is also pasted on the middle portion of the FPC board in the board feeding direction.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0026] like Figure 1-3 As shown, the utility model discloses a water absorption and transmission system for improving wrinkles of an FPC board, which is used to remove impurities from the surface of the FPC board 1, including:

[0027] A conveying device, comprising a first roller group 21 and a second roller group 22 arranged at intervals along a first direction, wherein the first roller group 21 and the second roller group 22 can transport the FPC board 1 along the first direction;

[0028] A sponge roller group 3, comprising a plurality of sponge rollers spaced apart along a first direction, the sponge rollers being located between the first roller group 21 and the second roller group 22;

[0029] The pasting and guiding frame 4 is a frame body for the FPC board 1 to be attached. After the FPC board 1 is attached, the pasting and guiding frame 4 can be transported on the conveying device and the sponge roller group 3 to prevent the FPC board 1 from being deformed.

[0030] Using the above structure, the FPC board 1 is first attached to the mounting frame 4, securing it so that it does not fall off. The mounting frame 4, with the FPC board 1 attached, is then placed into the conveyor. The first roller assembly 21 conveys the FPC board 1, which then passes over the sponge roller assembly 3 to remove any remaining liquid. The FPC board 1 is then conveyed out of the conveyor by the second roller assembly 22. The order of conveyance for the FPC board 1 is the first roller assembly 21, the sponge roller assembly 3, and the second roller assembly 22.

[0031] Specifically, the first roller group 21 and the second roller group 22 are arranged in the form of a horizontal transmission line to form a stable transmission channel. The FPC board 1 can pass smoothly in the transmission system to avoid wrinkles or deformation caused by instability during the transmission process. The pasting frame 4 is an annular frame structure. The frame area of ​​the pasting frame 4 is larger than the area of ​​the FPC board 1. The FPC board 1 can be attached to the pasting frame 4. The pasting frame 4 has a thickness, so it is less likely to deform than the FPC board 1, thereby preventing the FPC board 1 from wrinkling. After the FPC board 1 is conveyed to the sponge roller group 3 by the first roller group 21, the sponge roller group 3 contacts the FPC board 1 and absorbs moisture into the sponge. The FPC board 1 is supported by the pasting frame 4 to maintain a flat state, ensuring that no deformation occurs during the entire transmission process. While maintaining its physical shape, the FPC board 1 completes the removal of excess surface material, providing a good foundation for subsequent processes.

[0032] Preferably, the guide frame 4 is made of a fiberglass board with a thickness of 0.5-0.7 mm. The guide frame 4 can effectively protect the edges and surface of the FPC board 1 and prevent the FPC board 1 from deforming and damaging when passing through the conveyor or sponge roller assembly 3, thereby reducing the scrap rate and thus reducing material loss during production.

[0033] In this embodiment, there are at least two sponge roller groups 3, which are arranged up and down. When the FPC board 1 passes through the sponge roller group 3, the upper and lower sponge roller groups 3 can contact the upper surface and lower surface of the FPC board 1 at the same time. Since the two rollers work at the same time, the speed of moisture removal can be accelerated compared to the processing of a single roller, thereby improving the overall production efficiency and adapting to the needs of large-scale production through double-sided water absorption.

[0034] In this embodiment, the second roller assembly 22 includes several rollers arranged vertically and conveyed in a horizontal direction, with the rollers staggered in the vertical direction. The vertically arranged rollers can effectively increase the contact area with the FPC board 1, thereby improving conveying efficiency and reducing the possibility of wrinkles. The vertically staggered rollers can provide more uniform support and avoid excessive local stress. This staggered layout can effectively disperse the pressure on the FPC board 1 during conveyance, preventing deformation or damage caused by uneven stress. The combination of the vertical arrangement and staggered design enables the conveying system to operate stably at higher speeds, improve overall production efficiency, and meet the needs of large-scale production.

[0035] In this embodiment, the linear speeds of the conveying device and the sponge roller group 3 can be controlled separately, and the conveying speed of the guide frame 4 on the sponge roller group 3 is lower than its conveying speed on the conveying device. Since there is liquid residue on the FPC board 1, when the sponge roller group 3 contacts the FPC board 1, the friction of the sponge roller group 3 section will increase, resulting in a slowdown. At this time, the conveying speed at the first roller group 21 is faster than the speed of the water-absorbing sponge section, and the FPC board 1 will wrinkle forward. For example, in an actual production line, when the FPC board 1 enters the sponge roller group 3 section, the conveying speed of the rear section of the FPC board 1 is 0.05-0.2m / min faster than the conveying speed of the front section. Therefore, by adjusting the linear speed of the conveying device and the sponge roller group 3, a gradual transition is made, the impact of the speed mutation on the FPC board 1 is reduced, and on the basis of the support of the guide frame 4, the occurrence of wrinkling problems is further prevented.

[0036] In this embodiment, the FPC board 1 can be secured to the mounting frame 4 using adhesive tape. Specifically, the four ends of the FPC board 1 are secured to the mounting frame 4 with adhesive tape. This effectively prevents the FPC board 1 from moving due to vibration or gravity during transport, ensuring its stability and positional accuracy throughout the entire transport process. Furthermore, applying adhesive tape to the middle portion of the board feed direction provides additional support, helping to prevent the FPC board 1 from bending or deforming during transport, thereby maintaining its original shape.

[0037] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
