Description

Technical Field

[0001] The invention belongs to the technical field of flexible circuit board auxiliary material laminating, in particular to an FPC flexible circuit board reinforcement sheet laminating machine. Background Art

[0002] Flexible printed circuit is a flexible printed circuit board, which is mainly made of flexible insulating materials such as polyimide or polyester film as the substrate, with conductive patterns formed on it. Due to its characteristics of free bending, winding and folding, it is widely used in various electronic products that need to be miniaturized and lightweight, such as mobile phones, digital cameras, portable computers, etc. The FPC reinforcement sheet laminating machine is mainly used to accurately fit the reinforcement sheet on the FPC flexible circuit board to enhance its structural strength and durability.

[0003] A Chinese patent with announcement number CN219204848U discloses a device for measuring and laminating a reinforcing sheet for a flexible circuit board. In the invention, the FPC feeding mechanism realizes automatic adsorption of the flexible circuit board and sends it to the laminating workbench for positioning. Then the cover plate conveying mechanism sends the cover plate to the top of the flexible circuit board. The reinforcing sheet feeding mechanism adsorbs the reinforcing sheet and sends it to the reinforcing sheet measuring groove of the cover plate. After the reinforcing sheet falls into the bottom of the reinforcing sheet measuring groove, it is bonded to the flexible circuit board, reducing the situation where the reinforcing sheet is not skewed during lamination, ensuring that the reinforcing sheet can be controlled within the tolerance range after lamination, and improving the utilization rate of auxiliary materials.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, an FPC flexible circuit board reinforcement sheet bonding machine described in an embodiment of the present invention comprises a base 1, a bonding assembly is arranged above the base 1, the bonding assembly comprises a positioning shaft 2, two groups of rotating rings 3 are rotatably installed on the inner wall of the positioning shaft 2, bonding plates 4 are symmetrically arranged on the outer wall of the positioning shaft 2, and the two bonding plates 4 are respectively fixedly installed between each group of rotating rings 3, a support block 5 is fixedly installed on the bottom of the positioning shaft 2, and arc-shaped automatic telescopic rods 6 are symmetrically fixedly installed on the outer wall of the support block 5, and the 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 bonding plates 4, and a feeding assembly is arranged on the outside of the positioning shaft 2; the base 1 supports the equipment to ensure the stability of the equipment when it is working, and when performing the bonding work, multiple flexible circuit boards and reinforcement sheets are respectively fed to the top of the two bonding plates 4 through the feeding assembly, The support block 5 provides a fulcrum for the arc-shaped automatic telescopic rod 6, so that the end of the arc-shaped automatic telescopic rod 6 away from the support block 5 can be telescoped, and the arc-shaped automatic telescopic rod 6 is started to extend synchronously, and the swivel 3 can rotate on the positioning shaft 2, and the bonding plate 4 is connected to the swivel 3, thereby providing conditions for the movement of the bonding plate 4, so that the bonding plate 4 can rotate around the positioning shaft 2. When the arc-shaped automatic telescopic rod 6 is extended, it will push the two bonding plates 4 to rotate upward around the positioning shaft 2 and approach each other, and finally make the multiple flexible circuit boards and reinforcement sheets respectively located on the two bonding plates 4 bonded, so as to realize the bonding of the reinforcement sheets of the flexible circuit boards. Through the technical solution in the present invention, the reinforcement sheet bonding work can be performed on multiple flexible circuit boards at the same time, which solves the problem that traditional equipment can only perform one reinforcement sheet bonding work at a time, and effectively improves the working efficiency of the equipment.

[0024] like Figures 1 to 3As shown, the loading assembly includes a flexible circuit board loading assembly, a reinforcing sheet loading assembly A and a reinforcing sheet loading assembly B. The flexible circuit board loading assembly and the reinforcing sheet loading assembly A are symmetrically arranged, and the reinforcing sheet loading assembly B is located above the flexible circuit board loading assembly. The flexible circuit board loading assembly, the reinforcing sheet loading assembly A and the reinforcing sheet loading assembly B have the same structure. The flexible circuit board loading assembly includes a feeding plate 7 located above the base 1, and the feeding plate 7 is tilted. One side of the two bonding plates 4 is provided with an adsorption assembly; the flexible circuit board and the reinforcing sheet will be transported to the feeding plate 7 through an external connection device. Since the feeding plate 7 is tilted, the flexible circuit board and the reinforcing sheet will slide along the feeding plate 7 to the top of the bonding plate 4, thereby realizing the loading work. When the bonding work is performed, in the initial state, the two bonding plates 4 are respectively connected to the flexible circuit board loading assembly and the reinforcing sheet loading assembly A is aligned, the flexible circuit board and the reinforcing sheet slide to the top of the two bonding plates 4 through the flexible circuit board feeding component and the reinforcing sheet feeding component A respectively, and then the two bonding plates 4 are close to each other for bonding. When the bonding is completed, the two bonding plates 4 will be separated, and the flexible circuit board that has been bonded will move together with the bonding plate 4 close to the reinforcing sheet feeding component A under the action of the adsorption component. After the two bonding plates 4 are separated, the bonding plate 4 in an empty state will rotate to be aligned with the reinforcing sheet feeding component B, and then the reinforcing sheet feeding component B will transport another group of reinforcing sheets, and this group of reinforcing sheets will slide along the reinforcing sheet feeding component B to the top of the bonding plate 4 in an empty state, and then the two bonding plates 4 will be close again, and the new reinforcing sheet will be bonded to the other side of the flexible circuit board, thereby realizing the work of bonding the reinforcing sheets on both sides of the flexible circuit board, increasing the convenience of the device.

[0025] like Figures 1 to 4 and Figure 7 As shown, a plurality of groups of positioning plates 8 are fixedly installed on the outer wall of the feeding plate 7, and each group of positioning plates 8 has two and is symmetrically arranged. The outer wall of the bonding plate 4 is provided with a long groove 9 adapted to the positioning plates 8; 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, and 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 shifting during the conveying process, thereby ensuring the accuracy of the subsequent bonding work, and the long groove 9 is used for the positioning plate 8 to pass through to prevent the positioning plate 8 from blocking the normal rotation of the bonding plate 4.

[0026] like 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 bonding plate 4 rotates, the limit plate 11 will be squeezed, thereby causing the limit plate 11 to flip over. 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.

[0027] like Figure 3 , Figure 7 and Fig.10 As shown, force-bearing plates 12 are fixedly installed at both ends of the torsion spring shaft 10, and stoppers 13 are symmetrically fixedly installed on the outer wall of the bonding plate 4, and the outer walls of the stoppers 13 are respectively fitted with the outer walls of the corresponding force-bearing plates 12; when the bonding plate 4 flips downward, the limit plate 11 will be directly squeezed, and when the bonding plate 4 rotates upward, the stoppers 13 will rotate with the bonding plate 4, and when the stoppers 13 rotate, the force-bearing plate 12 will be squeezed, and the force-bearing plate 12 will rotate after being squeezed, and the force-bearing plate 12 is fixed to the inner shaft of the torsion spring shaft 10. 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 reinforcement sheet when the bonding plate 4 rotates upward.

[0028] like Figures 5 and 6 As shown, the adsorption component 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, and the inner wall of the air duct 14 is connected to a plurality of shunt pipes 16. The shunt pipe 16 extends from one end of the air duct 14 to the inside of the bonding plate 4 and is fixedly installed with a suction cup 17. The plurality of 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 cup 17, and 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 the flexible circuit board and the reinforcement sheet are adsorbed by the suction cup 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.

[0029] like Figure 11 to Figure 12As shown, a flexible pressing block 18 is slidably mounted on the inner wall of the limit plate 11, a support plate 19 is symmetrically fixedly mounted on the outer wall of the flexible pressing block 18, an elastic member 20 is symmetrically fixedly mounted between the outer wall of the support plate 19 and the inner wall of the limit plate 11, an extrusion block 21 is slidably mounted on the inner wall of the limit plate 11, the outer wall of the extrusion block 21 is slidably connected to the inner wall of the flexible pressing block 18, and a linear telescopic rod 22 is fixedly mounted between the outer wall of the extrusion block 21 and the inner wall of the limit plate 11; the suction cup 17 is used to align the flexible circuit board and the compensation Before the reinforcing sheet is adsorbed and fixed, the linear telescopic rod 22 is started, and the linear telescopic rod 22 is extended to push the squeezing block 21 to move. When the squeezing block 21 moves, it will squeeze the flexible pressing block 18 to move in the direction of the flexible circuit board or the reinforcing sheet. The flexible circuit board and the reinforcing sheet are squeezed by the flexible pressing block 18, so that the flexible circuit board and the reinforcing sheet can fit with the suction cup 17, thereby ensuring that the suction cup 17 can effectively adsorb the flexible circuit board and the reinforcing sheet, avoiding the situation where the adsorption is not achieved and the sheet falls off.

[0030] like Figure 1 to Figure 2 As shown, a blanking plate 23 is arranged below the reinforcing sheet loading component A, and the blanking plate 23 is arranged at an angle, and a plurality of partitions 24 are fixedly installed on the inner wall of the blanking plate 23; when the flexible circuit board completes the reinforcing sheet bonding work, the adsorption component away from the blanking plate 23 stops working, and the adsorption component close to the blanking plate 23 continues to adsorb the flexible circuit board, and then the two bonding plates 4 are unfolded to both sides, and the flexible circuit board follows the bonding plate 4 close to the blanking plate 23 under the action of the adsorption component (when performing the secondary bonding work of the flexible circuit board, the above method is also used), when the bonding plate 4 is rotated to be aligned with the blanking plate 23, the adsorption component no longer adsorbs, and the flexible circuit board slides down to the inner side of the blanking plate 23 under the action of gravity, so as to perform automatic unloading work, and the flexible circuit board can be unloaded in an orderly manner through the setting of the partition 24.

[0031] like Figure 1 As shown, the inner wall of the base 1 is provided with a positioning groove, and a collection box 25 is slidably installed on the inner wall of the positioning groove, a guide wheel is fixedly installed on the bottom of the collection box 25, and an armrest is fixedly installed on one side of the collection box 25; the collection box 25 can be quickly positioned through the positioning groove, and the flexible circuit board that has completed the bonding work slides along the blanking plate 23 into the collection box 25 for collection, and the movement of the collection box 25 is facilitated by the provided armrest and guide wheel.

[0032] like Figure 1 to Figure 2As shown, a support frame 26 is symmetrically 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, and a circular fixing plate 27 is fixedly installed on the adjacent side of the two support frames 26, and the feed plate 7 and the discharge plate 23 are fixedly installed between the two circular fixing plates 27; the base 1 serves as a support for the entire device to ensure the stability of the device, the support frame 26 is used to fix the positioning shaft 2, and the circular fixing plate 27 is used to fix the feed plate 7 and the discharge plate 23, so that each component is located in a suitable position, which is convenient for the use of the device.

[0033] Working principle: When performing the bonding work, multiple flexible circuit boards and reinforcing sheets are respectively fed to the top of the two bonding plates 4 through the feeding assembly, and then the arc-shaped automatic telescopic rod 6 is started to extend synchronously. When the arc-shaped automatic telescopic rod 6 is extended, it will push the two bonding plates 4 upward and close to each other, and finally make the multiple flexible circuit boards and reinforcing sheets respectively located on the two bonding plates 4 bonded, thereby realizing the bonding work of the reinforcing sheets of the flexible circuit boards. Through the technical solution of the present invention, the reinforcing sheet bonding work can be performed on multiple flexible circuit boards at the same time, which solves the problem that traditional equipment can only perform one reinforcing sheet bonding work at a time, and effectively improves the working efficiency of the equipment. The flexible circuit boards and reinforcing sheets will be transported to the feeding plate 7 through the external connection device. Since the feeding plate 7 is inclined, the flexible circuit boards and reinforcing sheets will slide along the feeding plate 7 to the top of the bonding plate 4, thereby realizing the feeding work. When performing the bonding work, in the initial state, the two bonding plates 4 is aligned with the flexible circuit board feed component and the reinforcing sheet feed component A respectively, the flexible circuit board and the reinforcing sheet slide down to the top of the two bonding plates 4 through the flexible circuit board feed component and the reinforcing sheet feed component A respectively, and then the two bonding plates 4 are close to each other for bonding work, when the bonding is completed, the two bonding plates 4 will be separated, and the flexible circuit board that has been bonded will move with the bonding plate 4 close to the reinforcing sheet feed component A under the action of the adsorption component, after the two bonding plates 4 are separated, the bonding plate 4 in the empty state will rotate to be aligned with the reinforcing sheet feed component B, and then the reinforcing sheet feed component B will transport another group of reinforcing sheets, and this group of reinforcing sheets will slide down to the top of the bonding plate 4 in the empty state along the reinforcing sheet feed component B, and then the two bonding plates 4 will be close to each other again, and the new reinforcing sheet will be bonded to the other side of the flexible circuit board, thereby realizing the work of bonding the reinforcing sheets on both sides of the flexible circuit board, increasing the convenience of the device.

[0034] 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, thereby causing the limit plate 11 to flip. 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 reinforcement sheet when the bonding plate 4 rotates upward.

[0035] When the flexible circuit board and the reinforcing sheet stop sliding down under the action of the limit plate 11, the flexible circuit board and the reinforcing sheet will be located above the suction cup 17, and the negative pressure machine 15 will generate negative pressure on the suction cup 17 under the action of the air guide tube 14 and the shunt tube 16, and the flexible circuit board and the reinforcing sheet are adsorbed by the suction cup 17, so as to fix the position of the flexible circuit board and the reinforcing sheet to prevent the position of the flexible circuit board and the reinforcing sheet from changing when the laminating plate 4 rotates, thereby ensuring the accuracy during laminating. Before the suction cup 17 adsorbs and fixes the flexible circuit board and the reinforcing sheet, the linear telescopic rod 22 is started, and the linear telescopic rod 22 is extended to push the extrusion block 21 to move. When the extrusion block 21 moves, it will squeeze the flexible pressing block 18 to move in the direction of the flexible circuit board or the reinforcing sheet, and the flexible circuit board and the reinforcing sheet are squeezed by the flexible pressing block 18, so that the flexible circuit board and the reinforcing sheet are The strengthening sheet can be fitted with the suction cup 17, thereby ensuring that the suction cup 17 can effectively adsorb the flexible circuit board and the reinforcing sheet to avoid the situation where the adsorption is not achieved and the sheet falls off. When the flexible circuit board completes the bonding work of the reinforcing sheet, the adsorption component on the side away from the blanking plate 23 stops working, and the adsorption component close to the blanking plate 23 continues to adsorb the flexible circuit board. Then the two bonding plates 4 are unfolded to both sides. The flexible circuit board follows the bonding plate 4 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 is rotated to be aligned with the blanking plate 23, the adsorption component no longer adsorbs, and the flexible circuit board slides down to the inner side of the blanking plate 23 under the action of gravity, thereby performing automatic unloading. The flexible circuit board can be unloaded in an orderly manner through the setting of the partition 24.
