Description

Technical Field

[0001] The present invention belongs to the technical field of flexible circuit board auxiliary material lamination, and specifically relates to an FPC flexible circuit board reinforcement sheet laminator. Background Art

[0002] A flexible printed circuit is a flexible printed circuit board mainly made of flexible insulating materials such as polyimide or polyester film, on which a conductive pattern is formed. Due to its characteristics of being freely bendable, wound, folded, etc., it is widely used in various electronic products that require miniaturization and lightweight, such as mobile phones, digital cameras, laptop computers, etc. The FPC reinforcement sheet laminator is mainly used to accurately laminate the reinforcement sheet on the FPC flexible circuit board to enhance its structural strength and durability.

[0003] A Chinese patent with the publication number CN219204848U discloses a device for measuring and laminating reinforcement sheets for flexible circuit boards. In this invention, the FPC feeding mechanism realizes the automatic adsorption of the flexible circuit board and sends it to the laminating workbench for positioning. Then, the cover plate handling mechanism sends the cover plate above the flexible circuit board, and the reinforcement sheet feeding mechanism adsorbs and sends the reinforcement sheet into the reinforcement sheet measuring groove of the cover plate. After the reinforcement sheet falls to the bottom of the reinforcement sheet measuring groove, it is bonded to the flexible circuit board, reducing the situation of non-deviation in the lamination of the reinforcement sheet, ensuring that the reinforcement sheet can be controlled within the tolerance range after lamination, and improving the utilization rate of auxiliary materials.

[0004] In the current prior art, when performing the reinforcement sheet lamination work, generally, a robotic arm drives a suction cup to move. After the reinforcement sheet is sucked up by the suction cup, the robotic arm drives the reinforcement sheet to move above the flexible circuit board to achieve the lamination work. Although this method can complete the lamination work, it can only achieve the lamination work of one flexible circuit board each time, resulting in low work efficiency.

Specific embodiments

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figures 1 to 5 shown, a FPC flexible circuit board reinforcement patch laminating machine according to an embodiment of the present invention includes a base 1, a laminating assembly is arranged above the base 1. The laminating assembly includes a positioning shaft 2, and two groups of swivel rings 3 are rotatably installed on the inner wall of the positioning shaft 2. Fitting plates 4 are symmetrically arranged on the outer wall of the positioning shaft 2, and the two fitting plates 4 are respectively fixedly installed between each group of swivel rings 3. A support block 5 is fixedly installed at the bottom of the positioning shaft 2, and arc-shaped automatic telescopic rods 6 are symmetrically and fixedly installed on the outer wall of the support block 5. One ends of the two arc-shaped automatic telescopic rods 6 away from the support block 5 are respectively fixedly connected to the outer walls of the two fitting plates 4. A feeding assembly is arranged outside the positioning shaft 2; the base 1 supports the equipment to ensure the stability of the equipment during operation. During the laminating operation, multiple flexible circuit boards and reinforcement patches are respectively fed above the two fitting plates 4 through the feeding assembly. The support block 5 provides a fulcrum for the arc-shaped automatic telescopic rod 6, so that one end of the arc-shaped automatic telescopic rod 6 away from the support block 5 can extend and retract. Start the arc-shaped automatic telescopic rod 6 to synchronously extend. The swivel ring 3 can rotate on the positioning shaft 2, and the fitting plate 4 is connected to the swivel ring 3, thereby providing conditions for the movement of the fitting plate 4, enabling the fitting plate 4 to rotate around the positioning shaft 2. When the arc-shaped automatic telescopic rod 6 extends, it will push the two fitting plates 4 to rotate upward around the positioning shaft 2 and approach each other, and finally make multiple flexible circuit boards and reinforcement patches located on the two fitting plates 4 fit together, realizing the reinforcement patch laminating work for the flexible circuit board. Through the technical solution in the present invention, the reinforcement patch laminating work for multiple flexible circuit boards can be carried out simultaneously, solving the problem that the traditional equipment can only carry out one reinforcement patch laminating work at a time, and effectively improving the working efficiency of the equipment.

[0037] As Figures 1 to 3As shown, the feeding component includes a flexible printed circuit board feeding component, a reinforcing sheet feeding component A, and a reinforcing sheet feeding component B. The flexible printed circuit board feeding component and the reinforcing sheet feeding component A are symmetrically arranged. The reinforcing sheet feeding component B is located above the flexible printed circuit board feeding component. The flexible printed circuit board feeding component, the reinforcing sheet feeding component A, and the reinforcing sheet feeding component B have the same structure. The flexible printed circuit board feeding component includes a feeding plate 7 located above the base 1. The feeding plate 7 is inclined. Adsorption components are arranged on one side of each of the two fitting plates 4. The flexible printed circuit board and the reinforcing sheet are conveyed to the feeding plate 7 through an external connecting device. Since the feeding plate 7 is inclined, the flexible printed circuit board and the reinforcing sheet will slide down along the feeding plate 7 to above the fitting plates 4, thus realizing the feeding work. When performing the fitting work, in the initial state, the two fitting plates 4 are respectively aligned with the flexible printed circuit board feeding component and the reinforcing sheet feeding component A. The flexible printed circuit board and the reinforcing sheet respectively slide down through the flexible printed circuit board feeding component and the reinforcing sheet feeding component A to above the two fitting plates 4. Then the two fitting plates 4 move closer to perform the fitting work. When the fitting is completed, the two fitting plates 4 will separate. The already fitted flexible printed circuit board will move together with the fitting plate 4 close to the reinforcing sheet feeding component A under the action of the adsorption component. After the two fitting plates 4 are separated, the vacant fitting plate 4 will rotate to be aligned with the reinforcing sheet feeding component B. Then the reinforcing sheet feeding component B will convey another set of reinforcing sheets. This set of reinforcing sheets will slide down along the reinforcing sheet feeding component B to above the vacant fitting plate 4. Then the two fitting plates 4 move closer again, and the new reinforcing sheet will be fitted on the other side of the flexible printed circuit board, thus realizing the work of fitting the reinforcing sheets on both sides of the flexible printed circuit board and increasing the convenience of the device.

[0038] As Figures 1 to 4 and Figure 7 shown, a number of groups of positioning plates 8 are fixedly installed on the outer wall of the feeding plate 7. The number of each group of positioning plates 8 is two and they are symmetrically arranged. Long grooves 9 adapted to the positioning plates 8 are formed on the outer wall of the fitting plate 4. When the flexible printed circuit board and the reinforcing sheet are fed through the feeding plate 7, the flexible printed circuit board and the reinforcing sheet will pass between each group of positioning plates 8. The positioning plates 8 can position the flexible printed circuit board and the reinforcing sheet to prevent the flexible printed circuit board and the reinforcing sheet from shifting during the conveying process, thus ensuring the accuracy of the subsequent fitting work. The long grooves 9 are used for the positioning plates 8 to pass through to prevent the positioning plates 8 from blocking the normal rotation of the fitting plate 4.

[0039] As Figures 7 to 9As shown, a torsion spring shaft 10 is fixedly installed between the inner walls of several groups of positioning plates 8, and several limiting plates 11 are fixedly installed on the outer wall of the torsion spring shaft 10, each limiting plate 11 is respectively located between each group of positioning plates 8, and the outer wall of the limiting plate 11 is in contact with the outer wall of the bonding plate 4; when the flexible circuit board and the reinforcing sheet slide downward, the limiting plate 11 will block the sliding flexible circuit board and the reinforcing sheet, and the flexible circuit board and the reinforcing sheet will eventually stay on the inner side of the limiting plate 11 when unloading, preventing the flexible circuit board and the reinforcing sheet from sliding downward. When the circuit board and the reinforcing sheet slide down, they pass over the positioning shaft 2 due to the high speed. To ensure the subsequent effective bonding, the positioning plate 8 is connected to the outer shaft of the torsion spring shaft 10, and the limit plate 11 is connected to the inner shaft of the torsion spring shaft 10. Therefore, the limit plate 11 has the ability to flip and reset to both sides. When the bonding plate 4 rotates, the limit plate 11 will be squeezed, so that the limit plate 11 will flip. When the bonding plate 4 passes over the limit plate 11, the limit plate 11 will be reset under the action of the torsion spring shaft 10.

[0040] If Figure 3 、 Figure 7 and Figure 10 As shown in the figure, both ends of the torsion spring shaft 10 are fixedly installed with a force-bearing plate 12, and the outer wall of the bonding plate 4 is symmetrically fixedly installed with a stopper 13, and the outer wall of the stopper 13 is respectively fitted with the outer wall of the corresponding force-bearing plate 12; when the bonding plate 4 is flipped downward, it will directly squeeze the limit plate 11, and when the bonding plate 4 rotates upward, the stopper 13 will rotate with the bonding plate 4, and when the stopper 13 rotates, it will squeeze the force-bearing plate 12, and the force-bearing plate 12 will rotate after being squeezed. The force-bearing plate 12 is fixed to the inner shaft of the torsion spring shaft 10, and when the force-bearing plate 12 rotates, it will drive the limit plate 11 to rotate, so that the limit plate 11 is separated from the bonding plate 4, thereby preventing the limit plate 11 from affecting the position of the flexible circuit board and the reinforcing sheet when the bonding plate 4 rotates upward.

[0041] If Figures 5 to 6 As shown in FIG. 1 , the adsorption assembly includes an air duct 14 located on one side of the bonding plate 4, and a negative pressure machine 15 is fixedly installed on the outer wall of the air duct 14. The outer wall of the negative pressure machine 15 is fixedly connected to the outer wall of the bonding plate 4. The inner wall of the air duct 14 is connected to a plurality of shunt pipes 16. The shunt pipes 16 extend from one end of the air duct 14 to the inside of the bonding plate 4 and are fixedly installed with suction cups 17. The suction cups 17 are respectively located between each group of positioning plates 8. When the flexible circuit board and the reinforcement sheet stop sliding down under the action of the limit plate 11, the flexible circuit board and the reinforcement sheet will be located above the suction cups 17. The negative pressure machine 15 will generate negative pressure on the suction cups 17 under the action of the air duct 14 and the shunt pipe 16, and the flexible circuit board and the reinforcement sheet are adsorbed by the suction cups 17, so as to fix the position of the flexible circuit board and the reinforcement sheet, prevent the position of the flexible circuit board and the reinforcement sheet from changing when the bonding plate 4 rotates, and ensure the accuracy during bonding.

[0042] If Figures 11 to 12 ​​​​As shown in the figure, a flexible pressing block 18 is slidably installed on the inner wall of the limit plate 11. Symmetrically fixed on the outer wall of the flexible pressing block 18 are support plates 19. Symmetrically fixed between the outer wall of the support plate 19 and the inner wall of the limit plate 11 are elastic members 20. A pressing block 21 is slidably installed on the inner wall of the limit plate 11. The outer wall of the pressing block 21 is slidably connected to the inner wall of the flexible pressing block 18. Fixed between the outer wall of the pressing block 21 and the inner wall of the limit plate 11 is a linear telescopic rod 22. Before the suction cup 17 adsorbs and fixes the flexible circuit board and the reinforcing patch, the linear telescopic rod 22 is activated. The linear telescopic rod 22 extends to push the pressing block 21 to move. When the pressing block 21 moves, it will squeeze the flexible pressing block 18 to move towards the flexible circuit board or the reinforcing patch. The flexible circuit board and the reinforcing patch are squeezed by the flexible pressing block 18, so that the flexible circuit board and the reinforcing patch can fit with the suction cup 17, thus ensuring that the suction cup 17 can effectively adsorb the flexible circuit board and the reinforcing patch and avoiding the situation of falling off without achieving adsorption.

[0043] As Figures 1 to 2 shown, a blanking plate 23 is arranged below the reinforcing patch feeding assembly A. The blanking plate 23 is inclined. Fixed on the inner wall of the blanking plate 23 are a number of partition plates 24. When the flexible circuit board completes the work of attaching the reinforcing patch, the adsorption assembly on the side far from the blanking plate 23 stops working, and the adsorption assembly on the side close to the blanking plate 23 continues to adsorb the flexible circuit board. Then the two attaching plates 4 unfold to both sides. The flexible circuit board moves along with the attaching plate 4 on the side close to the blanking plate 23 under the action of the adsorption assembly (when performing the secondary attaching work of the flexible circuit board, the above method is also used). When the attaching plate 4 rotates to align with the blanking plate 23, the adsorption assembly no longer adsorbs. The flexible circuit board slides down to the inner side of the blanking plate 23 under the action of gravity, thus performing the automatic blanking work. The flexible circuit board can be blanked orderly through the arrangement of the partition plates 24.

[0044] As Figure 1 shown, a positioning groove is arranged on the inner wall of the base 1. A collection box 25 is slidably installed on the inner wall of the positioning groove. Fixed to the bottom of the collection box 25 are guide wheels. Fixed to one side of the collection box 25 is a handrail. The collection box 25 can be quickly positioned through the positioning groove. The flexible circuit board that has completed the attaching work slides down along the blanking plate 23 and falls into the collection box 25 for collection. The movement of the collection box 25 is facilitated through the arranged handrail and guide wheels.

[0045] As Figures 1 to 2As shown in the figure, support frames 26 are symmetrically and fixedly installed on the top of the base 1. The positioning shaft 2 is fixedly installed between the inner walls of the two support frames 26. Circular fixing plates 27 are fixedly installed on one adjacent side of the two support frames 26. The feeding plate 7 and the blanking plate 23 are both fixedly installed between the two circular fixing plates 27. The base 1 serves as the support for the entire device to ensure the stability of the device. The support frames 26 are used to fix the positioning shaft 2, and the circular fixing plates 27 are used to fix the feeding plate 7 and the blanking plate 23, so that each component is in a suitable position, facilitating the use of the device.

[0046] Working principle: When performing the laminating work, multiple flexible printed circuit boards and reinforcing sheets are respectively fed above the two laminating plates 4 through the feeding assembly. Then, the arc-shaped automatic telescopic rod 6 is started to synchronously extend. When the arc-shaped automatic telescopic rod 6 extends, it will push the two laminating plates 4 to move closer to each other upward. Eventually, the multiple flexible printed circuit boards and reinforcing sheets located on the two laminating plates 4 are laminated, realizing the laminating work of the reinforcing sheets on the flexible printed circuit boards. Through the technical solution in the present invention, the laminating work of the reinforcing sheets can be carried out on multiple flexible printed circuit boards simultaneously, solving the problem that the traditional equipment can only perform the laminating work of one reinforcing sheet at a time, effectively improving the working efficiency of the equipment. The flexible printed circuit boards and the reinforcing sheets will be conveyed to the feeding plate 7 through an external connecting device. Since the feeding plate 7 is inclined, the flexible printed circuit boards and the reinforcing sheets will slide down along the feeding plate 7 to above the laminating plates 4, thus realizing the feeding work. When performing the laminating work, in the initial state, the two laminating plates 4 are respectively aligned with the flexible printed circuit board feeding assembly and the reinforcing sheet feeding assembly A. The flexible printed circuit boards and the reinforcing sheets respectively slide down through the flexible printed circuit board feeding assembly and the reinforcing sheet feeding assembly A to above the two laminating plates 4. Then, the two laminating plates 4 approach each other for the laminating work. When the laminating is completed, the two laminating plates 4 will separate. The already laminated flexible printed circuit boards will move together with the laminating plate 4 close to the reinforcing sheet feeding assembly A under the action of the adsorption assembly. After the two laminating plates 4 are separated, the vacant laminating plate 4 will rotate to align with the reinforcing sheet feeding assembly B. Then, the reinforcing sheet feeding assembly B will convey another set of reinforcing sheets, and this set of reinforcing sheets will slide down along the reinforcing sheet feeding assembly B to above the vacant laminating plate 4. Then, the two laminating plates 4 approach each other again, and the new reinforcing sheets will be laminated on the other side of the flexible printed circuit board, thus realizing the laminating work of the reinforcing sheets on both sides of the flexible printed circuit board and increasing the convenience of the device.

[0047] When the flexible circuit board and the reinforcing sheet are fed through the feeding plate 7, the flexible circuit board and the reinforcing sheet will pass between each group of positioning plates 8. The flexible circuit board and the reinforcing sheet can be positioned by the positioning plate 8 to prevent the flexible circuit board and the reinforcing sheet from being offset during the transportation process, thereby ensuring the accuracy of the subsequent bonding work. When the flexible circuit board and the reinforcing sheet slide down, the limiting plate 11 will block the sliding flexible circuit board and the reinforcing sheet. The flexible circuit board and the reinforcing sheet will eventually stay on the inner side of the limiting plate 11 during unloading, preventing the flexible circuit board and the reinforcing sheet from crossing the positioning shaft 2 due to excessive speed when sliding, thereby ensuring that effective bonding can be carried out subsequently. The positioning plate 8 is connected to the outer shaft of the torsion spring shaft 10, and the limiting plate 11 is connected to the inner shaft of the torsion spring shaft 10, so the limiting plate 11 is connected to the inner shaft of the torsion spring shaft 10. The plate 11 has the ability to flip and reset to both sides. When the bonding plate 4 rotates, it will squeeze the limit plate 11, so that the limit plate 11 flips. When the bonding plate 4 passes over the limit plate 11, the limit plate 11 will reset under the action of the torsion spring shaft 10. When the bonding plate 4 flips downward, it will directly squeeze the limit plate 11. When the bonding plate 4 rotates upward, the stop block 13 will rotate with the bonding plate 4. When the stop block 13 rotates, it will squeeze the force plate 12. After being squeezed, the force plate 12 will rotate. The force plate 12 is fixed to the inner shaft of the torsion spring shaft 10. When the force plate 12 rotates, it will drive the limit plate 11 to rotate, so that the limit plate 11 is separated from the bonding plate 4, thereby preventing the limit plate 11 from affecting the position of the flexible circuit board and the reinforcing sheet when the bonding plate 4 rotates upward.

[0048] After the flexible circuit board and the reinforcement sheet stop sliding under the action of the limiting plate 11, the flexible circuit board and the reinforcement sheet will be located above the suction cup 17. The negative pressure machine 15 will generate negative pressure on the suction cup 17 under the action of the air duct 14 and the shunt pipe 16, and adsorb the flexible circuit board and the reinforcement sheet through the suction cup 17, so as to fix the positions of the flexible circuit board and the reinforcement sheet, prevent the positions of the flexible circuit board and the reinforcement sheet from changing when the bonding plate 4 rotates, and ensure the accuracy during bonding. Before the suction cup 17 adsorbs and fixes the flexible circuit board and the reinforcement sheet, the linear telescopic rod 22 is started, and the linear telescopic rod 22 extends to push the extrusion block 21 to move. When the extrusion block 21 moves, it will squeeze the flexible pressing block 18 to move towards the flexible circuit board or the reinforcement sheet, and squeeze the flexible circuit board and the reinforcement sheet through the flexible pressing block 18, so that the flexible circuit board and the reinforcement sheet can be attached to the suction cup 17, thus ensuring that the suction cup 17 can effectively adsorb the flexible circuit board and the reinforcement sheet and avoid the situation of falling off due to failure to achieve adsorption. When the flexible circuit board completes the work of bonding the reinforcement sheet, the adsorption component on the side far from the blanking plate 23 stops working, and the adsorption component on the side close to the blanking plate 23 continues to adsorb the flexible circuit board. Then, the two bonding plates 4 unfold to both sides, and the flexible circuit board moves with the bonding plate 4 on the side close to the blanking plate 23 under the action of the adsorption component (the above method is also used when performing the secondary bonding work of the flexible circuit board). When the bonding plate 4 rotates to align with the blanking plate 23, the adsorption component stops adsorbing, and the flexible circuit board slides down to the inside of the blanking plate 23 under the action of gravity, so as to perform automatic blanking work. The flexible circuit board can be blanked orderly through the setting of the partition plate 24.
