Description

Technical Field

[0001] This utility model belongs to the field of FPC production equipment technology, and in particular relates to a fast FPC production equipment with a fully dry process. Background Technology

[0002] Flexible printed circuit boards (FPCs) 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, and thinness.

[0003] The production process of FPC using the dry process is as follows: material cutting → drilling → PTH → electroplating → ... shearing → electrical testing-punching → final inspection → packaging → shipping. During drilling, FPC requires packaging. A cover plate is selected and assembled with the FPC, and after being sealed with tape, a mark is made at the drilling point. Then, the drilling machine is used to drill. The cover plate has advantages such as preventing damage to the material surface caused by the drilling machine and pressure foot, facilitating drill tip centering, and avoiding drilling position deviation. However, the assembly of the cover plate and FPC is cumbersome, and they need to be disassembled after drilling, greatly reducing drilling efficiency and failing to meet the demand for rapid FPC production.

[0004] Therefore, a fast FPC production equipment with a completely dry process is proposed. Utility Model Content

[0023] This utility model embodiment provides a rapid FPC production equipment with a completely dry process, such as... Figure 1-4 As shown, the system includes a base 1, a limiting platform 2 fixedly mounted on the top of the base 1, an FPC limiting groove 3 at the center of the top of the limiting platform 2, a positioning groove 4 on one inner wall of the FPC limiting groove 3, a connecting slot 5 on the top of the limiting platform 2 near the positioning groove 4, a spring 6 embedded in the bottom of the FPC limiting groove 3, a top post 7 fixedly mounted on the top of the spring 6, a recessed hole for receiving the spring 6 and the top post 7 at the bottom of the FPC limiting groove 3, a spring plunger 8 embedded and fixedly mounted on the outer wall of the FPC limiting groove 3 adjacent to the positioning groove 4, a cover plate 9 above the limiting platform 2, a retaining plate 10 integrally formed on one outer wall of the cover plate 9, and a positioning block 11 integrally formed on the outer wall of the cover plate 9 adjacent to the retaining plate 10, the positioning groove 4 and the positioning block 11 matching and fitting together, a support plate 12 fixedly connected to the top of the base 1 near the limiting platform 2 by bolts, and the outer wall of the support plate 12... The support plate 12 has a through groove 13, and a movable frame 14 is slidably connected to the outer wall of the support plate 12. The support plate 12 and the movable frame 14 are slidably connected by a sliding groove with a T-shaped cross section. A laser lamp 15 is connected to the inner wall of the movable frame 14 by a damping shaft. A screw 16 is threadedly connected to the center of the outer wall of the movable frame 14 away from the laser lamp 15. The screw 16 is located inside the through groove 13 and passes through the through groove 13. An extrusion head 17 is integrally formed on the end of the screw 16 away from the movable frame 14. A fixed frame 18 is bolted to the top of the base 1 near the other side of the limiting platform 2. An electric push 19 is bolted to the top of the fixed frame 18. An XY axis cross translation stage 20 is fixedly connected to the output end of the electric push 19. A motor 21 is fixedly connected to the driving moving end of the XY axis cross translation stage 20. A drill bit 22 is fixedly connected to the output end of the motor 21.

[0024] It should be noted that the assembly of the cover plate and FPC is cumbersome, and the plates need to be disassembled after drilling, which greatly reduces drilling efficiency and fails to meet the requirements for rapid FPC production. In this embodiment, the drilling positions of the FPC and cover plate 9 are pre-positioned by the laser lamp 15, eliminating the need to mark each assembled FPC and cover plate 9. The cooperation between the limiting platform 2 and the cover plate 9 allows the cover plate 9 to protect the FPC during drilling, and the FPC and cover plate 9 are individually limited in the FPC limiting groove 3, eliminating the trouble of bonding and disassembling the FPC and cover plate 9, simplifying the operation steps, improving drilling efficiency, and meeting the requirements for rapid FPC production.

[0025] Specifically, in this embodiment, the solution mainly includes a limiting platform 2 and a cover plate 9. Before drilling the FPC, the FPC and the cover plate 9 are fixed together, and the required drilling positions are marked on the cover plate 9. Then, the FPC and the cover plate 9 are positioned together in the FPC limiting groove 3 with the cover plate 9 facing upwards. The position of the laser lamp 15 is adjusted according to the markings on the cover plate 9. The moving frame 14 is inserted into the support plate 12 and slides on its outer wall. By adjusting the rotation of the laser lamp 15 inside the moving frame 14, the laser angle emitted by the laser lamp 15 is adjusted. By adjusting the horizontal movement of the laser lamp 15, the laser emitted by the laser lamp 15 is illuminated at the marked position on the cover plate 9. At this time, the extrusion head 17 is rotated, and the extrusion head 17 drives the screw 16 to rotate. The screw 16 is gradually screwed into the moving frame 14, and the extrusion head 17 presses against the outer wall of the support plate 12. The extrusion friction is used to fix the position of the moving frame 14. After multiple laser lamps 15 are used to individually position multiple marks, the FPC and the cover plate 9 are removed. Plate 9 completes the pre-drilling positioning operation. During drilling, the FPC is placed in the FPC limiting groove 3. Positioned by the positioning groove 4 and positioning block 11, the cover plate 9 is also inserted into the FPC limiting groove 3. The cover plate 9 covers the FPC and is pressed downwards. The top post 7 is compressed, compressing the spring 6. The spring plunger 8 is used to fix the cover plate 9 at the height inside the FPC limiting groove 3. Then, the XY-axis cross translation stage 20 controls the position of the drill bit 22, adjusting the drill bit 22 to the desired position. The light 15 shines directly above the top of the cover plate 9. The electric drive 19 drives the XY axis cross translation stage 20 to move downward through its output end on one side. The motor 21 drives the drill bit 22 to rotate at high speed through its output end on one side. During the downward movement of the drill bit 22, it drills holes in the cover plate 9 and the FPC. After the drilling is completed, the clamping plate 10 is lifted upward, and the cover plate 9 is disengaged from the FPC limiting groove 3. Under the action of the spring 6, the top column 7 moves upward and pushes the FPC out, completing one FPC drilling process.

[0026] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the distance between the inner bottom of the FPC limiting groove 3 and the bottom of the cover plate 9 is the same as the thickness of the FPC.

[0027] In this embodiment, the FPC can be limited to ensure that the FPC can move between the bottom of the FPC limiting groove 3 and the bottom of the cover plate 9, thus ensuring the accuracy of drilling.

[0028] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the card plate 10 passes through the card slot 5 and protrudes from the card slot 5.

[0029] In this embodiment, the protruding retaining plate 10 facilitates the application of an upward force to the cover plate 9, thereby making it easier for the cover plate 9 to be removed from the FPC limiting groove 3.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, a positioning hole matching the spring plunger 8 is provided on one side of the outer wall of the cover plate 9.

[0031] In this embodiment, the cover plate 9 is positioned and fixed at the height inside the FPC limiting groove 3 by the cooperation of the spring plunger 8 and the positioning hole.
