Description

Technical Field

[0001] This utility model relates to the technical field of flexible circuit boards, and in particular to a novel FPC circuit board laminating machine. Background Technology

[0002] Flexible printed circuit boards (PCBs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending properties.

[0003] The gap between flexible circuit board products is connected by dry film. If the dry film is too long when the product passes through the DES line, there will be dry film fragments left. The residual dry film fragments stick to the rollers. When the board passes through the rollers, the dry film fragments stick back to the board surface, causing residual copper short circuit abnormalities. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a novel FPC circuit board laminating machine that restricts the position of flexible circuit boards during lamination, thereby controlling the distance between flexible circuit boards and the length of the dry film, thus reducing the possibility of short circuits.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A novel FPC circuit board laminating machine includes a laminating table, an adsorption plate fixedly connected to the upper end of the laminating table, a cavity opened at the upper end of the adsorption plate, and a sealing plate fixedly connected to the upper part of the side walls of the cavity, and multiple mounting brackets opened at the upper end of the sealing plate.

[0007] The upper end of the film application table is fixedly connected to two movable platforms. Multiple adsorption racks are slidably connected between the side walls of the two movable platforms. Vacuum disks are fixedly connected to both sides of the adsorption racks, and adsorption rubber pads are fixedly connected to the upper end of the vacuum disks.

[0008] Several limiting plates are provided on both sides of the adsorption plate, and two dry film rollers are provided above the film application table.

[0009] In a preferred embodiment, the present invention can be further configured such that: two limiting rods are fixedly connected between the side walls of the moving platform, and the adsorption frame is slidably connected to the circumferential side of the two limiting rods.

[0010] In a preferred embodiment, the present invention can be further configured such that: a plurality of limiting holes are provided on one side wall of the moving platform, and a plurality of screws are provided on one side of the moving platform, with the screw threads inserted into the adsorption frame.

[0011] In a preferred embodiment, the present invention can be further configured as follows: an adjusting component is provided below the limiting plate, the adjusting component includes a moving groove and a bidirectional lead screw, the moving groove is opened inside the film application table, a bidirectional lead screw is rotatably connected to one side wall of the moving groove, and the bidirectional lead screw moves through one side of the film application table, two moving plates are threadedly connected to the circumferential side of the bidirectional lead screw, and the upper ends of the two moving plates move through the upper end of the film application table and are fixed to the limiting plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: two sliding rods are fixedly connected between the side walls of the movable groove, and the movable plate is slidably connected to the circumferential side of the two sliding rods.

[0013] In a preferred embodiment, the present invention can be further configured as follows: mounting frames are installed on both sides of the dry film roller, and connecting plates are fixedly connected to both sides of the mounting frames; two film applicators are fixedly connected to both sides of the film applicator; and a hydraulic cylinder is fixedly connected between the connecting plates and the film applicators.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. The system includes a film application table, film application frame, suction tray, sealing plate, suction holes, moving platform, suction rack, and suction rubber pad. The suction tray is connected to an external air pump, and the vacuum plate is connected to an external vacuum pump. The corners of the FPC circuit board are placed on the suction rubber pad. The vacuum pump and air pump are then started. The air pump uses the cavity and suction holes to hold the main body of the FPC circuit board, while the suction rubber pad holds the bottom corners of the FPC circuit board, thus limiting its position. The suction rack is 2-5mm wide. The vacuum plates on both sides can suction the corners of two FPC circuit boards, ensuring a 2-5mm gap between adjacent FPC circuit boards. This controls the dry film spacing between two FPC circuit boards, effectively improving the problem of film breakage, re-adhesion, and short circuits caused by excessively long dry film gaps.

[0016] 2. A limit plate, a moving groove, a bidirectional lead screw, and a moving plate are provided. When the bidirectional lead screw is rotated, the moving plate moves linearly on the surface of the bidirectional lead screw. The moving plate drives the limit plate to move. The limit plate can adjust its position according to the width of the FPC circuit board, which can limit the placement position of the FPC circuit board and prevent the position of the FPC circuit board from being offset when it is placed.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0022] Reference Figure 1-3 The present invention discloses a novel FPC circuit board laminating machine, including a laminating table 1, an adsorption plate 10 fixedly connected to the upper end of the laminating table 1, a cavity 11 opened at the upper end of the adsorption plate 10, and a sealing plate 12 fixedly connected between the side walls of the cavity 11, and a plurality of mounting brackets 3 opened at the upper end of the sealing plate 12.

[0023] Two movable platforms 6 are fixedly connected to the upper end of the film application platform 1. Multiple adsorption racks 9 are slidably connected between the side walls of the two movable platforms 6. Vacuum disks 19 are fixedly connected to both sides of the adsorption racks 9. Adsorption rubber pads 20 are fixedly connected to the upper end of the vacuum disks 19.

[0024] Several limiting plates 15 are provided on both sides of the adsorption plate 10, and two dry film rollers 21 are provided above the film application table 1.

[0025] In this embodiment, the adsorption plate 10 is connected to an external air pump, and the vacuum plate 19 is connected to an external vacuum pump. The corners of the FPC circuit board are placed on the adsorption rubber pad 20. The vacuum pump and air pump are started. The air pump can hold the main body of the FPC circuit board through the cavity 11 and the adsorption hole 13. The adsorption rubber pad 20 can hold the bottom corners of the FPC circuit board, thereby limiting the position of the FPC circuit board. The width of the adsorption frame 9 is 2-5mm. The vacuum plates 19 on both sides can adsorb the corners of the two FPC circuit boards, so that the distance between two adjacent FPC circuit boards is 2-5mm. This controls the dry film distance between the two FPC circuit boards and effectively improves the problem of film breakage, re-adhesion, and short circuit caused by excessive dry film distance. Preferably, the upper end of the adsorption frame 9 is connected to the two sides with limit strips 24. When installing the FPC circuit board, it can be placed against the limit strips 24 to better limit the distance between the two FPC circuit boards. The upper end of the moving stage 6 is provided with a scale, which can better adjust the position of the adsorption frame 9 according to the length of the FPC circuit board.

[0026] For further details, please refer to Figure 3 Two limiting rods 14 are fixedly connected between the side walls of the moving platform 6, and the adsorption frame 9 is slidably connected to the circumferential side of the two limiting rods 14.

[0027] In this embodiment, the adsorption frame 9 can slide continuously on the circumferential side of the limiting rod 14, allowing the adsorption frame 9 to perform linear translational motion, thereby improving the movement stability of the adsorption frame 9.

[0028] For further details, please refer to Figure 3 The moving platform 6 has several limiting holes 7 on one side wall, and several screws 8 are provided on one side of the moving platform 6, with the screws 8 threaded into the adsorption frame 9.

[0029] In this embodiment, after the adsorption rack 9 is moved to the appropriate position, the screw 8 is passed through the limiting hole 7 and inserted into the adsorption rack 9, so that the adsorption rack 9 can be connected and fixed to the moving stage 6.

[0030] For further details, please refer to Figure 2 An adjusting component is provided below the limiting plate 15. The adjusting component includes a moving groove 22 and a bidirectional screw 17. The moving groove 22 is opened inside the film application table 1. The bidirectional screw 17 is rotatably connected to one side wall of the moving groove 22 and moves through one side of the film application table 1. Two moving plates 16 are threaded to the circumferential side of the bidirectional screw 17 and the upper ends of the two moving plates 16 move through the upper end of the film application table 1 and are fixed to the limiting plate 15.

[0031] In this embodiment, a motor 23 is fixedly connected to one side of the film application table 1. The output end of the motor 23 is fixed to the bidirectional lead screw 17. When the motor 23 is started, the output end of the motor 23 drives the bidirectional lead screw 17 to rotate. The moving plate 16 is threadedly connected to the circumferential side of the bidirectional lead screw 17 through the lead screw nut. The moving plate 16 moves linearly on the surface of the bidirectional lead screw 17. The moving plate 16 drives the limiting plate 15 to move. The limiting plate 15 can adjust its position according to the width of the FPC circuit board, and can limit the placement position of the FPC circuit board to prevent the position of the FPC circuit board from shifting when it is placed.

[0032] For further details, please refer to Figure 2 Two slide rods 18 are fixedly connected between the side walls of the movable groove 22, and the movable plate 16 is slidably connected to the circumferential side of the two slide rods 18.

[0033] In this embodiment, the movable plate 16 makes a linear translational movement on the circumferential side of the slide bar 18, which can improve the movement stability of the movable plate 16 and the limiting plate 15.

[0034] For further details, please refer to Figure 1The dry film roller 21 is equipped with mounting brackets 3 on both sides, and the mounting brackets 3 are fixedly connected to the two sides of the mounting brackets 3. The film application table 1 is fixedly connected to two film application frames 2 on both sides, and a hydraulic cylinder 4 is fixedly connected between the connecting plate 5 and the film application frame 2.

[0035] In this embodiment, the connecting plate 5 is fixed to the inner top wall of the film applicator 2, and the output end of the hydraulic cylinder 4 is fixed to the connecting plate 5. When the hydraulic cylinder 4 is started, the hydraulic cylinder 4 can drive the mounting frame 3 to move up and down, thereby driving the dry film roller 21 to move down or up to apply film to the FPC circuit board.

[0036] The implementation principle of the above embodiment is as follows: the corners of the FPC circuit board are placed on the adsorption rubber pad 20, the vacuum pump and air pump are started, the air pump can hold the main body of the FPC circuit board through the cavity 11 and the adsorption hole 13, the adsorption rubber pad 20 can hold the bottom corners of the FPC circuit board, thereby limiting the position of the FPC circuit board. The width of the adsorption frame 9 is 2-5mm, and the vacuum disks 19 on both sides can adsorb the corners of the two FPC circuit boards, so that the distance between two adjacent FPC circuit boards is 2-5mm, controlling the dry film distance between the two FPC circuit boards, effectively improving the problem of film breakage, re-adhesion and short circuit caused by excessive dry film distance.
