Description

[0002] Due to its flexibility, thinness, and lightweight properties, flexible printed circuit boards (FPCs) have been widely used in applications such as smartphones and wearable devices. However, shortcomings such as FPC's pliability and insufficient connection reliability continue to restrict its further development.

A plurality of roller groups 6 are provided on both sides of the adjustable bonding mechanism 5, each of the roller groups 6 is wound with a reinforcing plate coil 13 and the pressure surface of the reinforcing plate coil 13 is in contact with the stamping end of the adjustable bonding mechanism 5, and the plate lifting mechanism 4 can move the FPC board close to the adjustable bonding mechanism 5 by lifting and lowering to perform reinforcing plate bonding processing.

[0025] The positioning and dust removal mechanism 3 includes a fixed plate 16 fixed to the workbench 1. A positioning frame 17 with a hollow center and a square structure is located on top of the fixing plate 16. The four inner side surfaces of the positioning frame 17 are all inclined surfaces. The positioning frame 17 has two opposing front and rear edges with movement slots 18, and two opposing left and right edges with placement slots 19. The hollow portion of the positioning frame 17 can be replaced with other shapes such as square and concave to accommodate the positioning of different FPC boards.

[0026] It also includes an electrostatic dust removal rod 20, each end of which is provided with a connecting rod 21 that slides and plugs into the two movable grooves 18 of the positioning frame 17. The workbench 1 is provided with an electric telescopic rod 22, the telescopic end of which is fixedly connected to the adjacent connecting rod 21. The telescopic direction of the electric telescopic rod 22 is the same as the direction of movement of the connecting rod 21 in the movable groove 18. The bottom surface of the placement groove 19 is provided with a dust collection groove, and a dust suction sticker is attached to the dust collection groove. The electrostatic dust removal rod 20 and the electric telescopic rod 22 are both connected to a controller. The electrostatic dust removal rod 20 can be stored in the placement groove 19 to prevent the receiving plate 34 from moving up and down. At the same time, the dust suction sticker can absorb and collect dust that falls after the electrostatic dust removal rod 20 stops working, preventing dust from dispersing. The dust suction sticker is attached to the dust collection groove by gluing the bottom to facilitate replacement. The electrostatic dust removal rod 20 is an existing mature technology and is not limited to it here.

[0027] The plate lifting mechanism 4 includes multiple spring bases 31 fixed to the workbench 1. Each spring base 31 is equipped with a telescopic spring 33. The top of each telescopic spring 33 is fixed with an electric telescopic rod 32. The upper end of the electric telescopic rod 32 is a telescopic end, and the telescopic ends of the electric telescopic rod 32 are commonly connected to a receiving plate 34.

The area of ​​the top of the receiving plate 34 is smaller than the area of ​​the hollow portion of the positioning frame 17, allowing the receiving plate 34 to pass through the positioning frame 17 and rise and fall. The telescopic spring 33 provides a cushioning effect when the punch 30 mates the FPC board and the reinforcing sheet coil 13, preventing damage to the FPC board. Four electric telescopic rods 32 are fixed to the four corners of the bottom of the receiving plate 34. The number and position of the contact sensors 35 can be adjusted according to the shape of the FPC board to detect different FPC shapes. When all contact sensors 35 are in contact with the FPC board, the FPC board is accurately positioned and delivered to the receiving plate 34. Otherwise, the FPC board's position is deviated, and the controller alerts the operator to check.

[0028] The adjustable fitting mechanism 5 comprises a slot plate 23. The workbench 1 is provided with a support plate 2. The slot plate 23 is fixed to the upper portion of the support plate 2. The slot plate 23 is provided with a plurality of slots 24. A slide rod 25 is slidably mounted within each slot 24. The lower end of each slide rod 25 extends outward from the slot 24, and an adjustment box 26 is fixed below the slot 24. There are three slots 24, but any additional number can be provided by replacing the slot plate 23. A compression nut 29 is threadedly connected to the top of a hydraulic rod 28. The compression nut 29 passes through the top of the hydraulic rod 28 and contacts the inner wall of the adjustment box 26, securing the hydraulic rod 28 in place.

[0029] The adjustment box 26 has interconnected connecting grooves 27 on one side and the bottom. A hydraulic rod 28 is inserted into the connecting groove 27 on the bottom of the adjustment box 26. A compression nut 29 is installed in the connecting groove 27 on the side of the adjustment box 26, which is connected to the end of the hydraulic rod 28. A punch 30 is mounted on the bottom of the hydraulic rod 28. One or more adjustment boxes 26 can be installed in the strip groove 24, and they can be replaced according to the needs of the reinforcement plate bonding. The slotting direction of the connecting groove 27 is arranged perpendicular to the slotting direction of the strip groove 24, and the hydraulic rod 28 and punch 30 can be moved at multiple angles in the plane through the connecting groove 27 and the strip groove 24, allowing for the simultaneous bonding of multiple different reinforcement plates to the same FPC board.

[0030] The reel group 6 includes a reel 8, a coiling drum 10 and a transition drum 9. The coiling drum 10 and the transition drum 9 are located on the same side of the adjustable fitting mechanism 5, and the reel 8 is located on the other side of the adjustable fitting mechanism 5 opposite thereto. The reinforcement plate coil 13 is wound on the coiling drum 10, and the reinforcement plate coil 13 bypasses the transition drum 9 and is reeled on the reel 8.

[0031] A fixing frame 12 is fixed on the workbench 1, and a plurality of bearing seats are provided on the fixing frame 12. A bearing rod 11 is connected between each bearing seat and the support plate 2, and each of the winding drum 8, coil drum 10 and transition drum 9 is respectively connected to the corresponding bearing rod 11. A plurality of drive motors 7 are provided on the support plate 2, among which the bearing rods 11 connected to the winding drum 8 are connected to the drive motor 7 one by one, and the drive motor 7 is electrically connected to the controller.

[0032] A feed conveyor belt 14 is installed on the workbench 1 on one side of the receiving plate 34, and a discharge conveyor belt 15 is installed on the workbench 1 on the other side of the receiving plate 34. The feed end of the feed conveyor belt 14 is higher than the positioning frame 17. Both the feed conveyor belt 14 and the discharge conveyor belt 15 are electrically connected to the controller. This height difference allows for automatic feeding and discharging of FPC boards.

[0033] A method for laminating an FPC board reinforcement sheet of the FPC board reinforcement laminating device as described above comprises the following steps:

[0034] 1) The FPC board is fed to the top of the receiving plate 34 via the feed conveyor belt 14. Simultaneously, the inner bevel of the positioning frame 17 defines the position of the FPC board. When all contact sensors 35 detect contact with the FPC board, the FPC board is accurately positioned on the receiving plate 34.

[0035] 2) The electric telescopic rod 22 is in operation, driving the electrostatic dust removal rod 20 through the connecting rod 21 to move along the movable groove 18 and sweep across the upper surface of the FPC board. During this period, the electrostatic dust removal rod 20 works to remove dust from the surface of the FPC board until it enters the placement groove 19. The electrostatic dust removal rod 20 stops working and the dust adsorbed on the surface of the electrostatic dust removal rod 20 falls into the dust collecting groove;

[0036] 3) The electric telescopic rod 22 operates to drive the receiving plate 34 upward, thereby raising the FPC board closer to the reinforcing plate coil 13 and the punch 30. The hydraulic rod 28 operates to press the punch 30 downward, and the punch 30 operates to attach the reinforcing plate on the reinforcing plate coil 13 to the FPC board, completing the attachment. After the hydraulic rod 28 is reset, the drive motor 7 operates to drive the reel 8 to rotate and reel the attached reinforcing plate coil 13;

[0037] 4) The electric telescopic rod 2 32 near the side of the discharge conveyor belt 15 retracts and resets, causing the receiving plate 34 to tilt toward the side of the discharge conveyor belt 15, thereby causing the bonded FPC board to fall onto the discharge conveyor belt 15 for discharge, and then all the electric conveyor belts 2 are reset to the positioning frame 17 and the above operation is repeated to bond the FPC board.

[0038] The present invention realizes the functions of automatic positioning adjustment and position detection of FPC boards, integrates loading, detection, positioning, dust removal, bonding and discharging, can automatically complete the reinforcement bonding work of FPC boards, and can simultaneously perform reinforcement bonding at multiple different positions on the same FPC board, reducing manual participation, thereby accelerating processing efficiency and improving the accuracy of bonding of reinforcement boards.
