For example, existing equipment often requires multiple steps during bending and manual intervention to correct positioning, which not only increases production costs but also easily leads to quality problems. Furthermore, existing equipment lacks adaptability and flexibility when handling different FPC products, failing to meet diverse production needs. Utility Model Content

[0003] This utility model discloses an FPC bending and bonding mechanism, which aims to solve the problems mentioned above.

[0004] An FPC bending and bonding mechanism includes an upper moving platform and a lower moving platform. The upper moving platform is equipped with a first lifting mechanism to drive the upper platform to rise and fall, and also has a bending mechanism for driving the FPC to bend downwards at a first preset angle.

[0020] Combination Figures 1 to 3 As shown, this embodiment provides an FPC bending and bonding mechanism, comprising an upper moving platform 1 and a lower moving platform 2. The upper moving platform 1 is equipped with a first lifting mechanism 3 to drive the upper platform 1 to rise and fall, and is also equipped with a bending mechanism 4 for driving the FPC to bend downwards at a first preset angle. The lower moving platform 2 is located below the upper moving platform 1 and includes an alignment platform 10, a bonding lower platform 11 disposed on the alignment platform 10, a positioning mechanism 12 disposed on the outside of the bonding lower platform 11, and a gripper mechanism 15. The bonding lower platform 11 is adapted to place a lower product, and the positioning mechanism 12 is adapted to work after the FPC is bent inwards at the first preset angle to continue bending the FPC inwards to a second preset angle. The gripper mechanism 15 is equipped with a second lifting mechanism 17, which is adapted to drive the gripper mechanism 15 to rise to grip the FPC when the FPC is at the second preset angle, and after gripping, descends synchronously with the first lifting mechanism 3 to pull the FPC to bond and connect with the lower product.

[0021] In this embodiment, the mechanism comprises two main parts: an upper moving platform 1 and a lower moving platform 2. Each part works in concert with the mechanical structure and drive system to achieve automated bending and bonding operations on flexible printed circuit boards (FPCs).

[0022] Combination Figures 1 to 2As shown, the upper moving platform 1 is located at the top of the entire mechanism, and its core components include a first lifting mechanism 3, a bonding upper platform 8, and a bending mechanism 4. The first lifting mechanism 3 can be a lifting cylinder or a linear motor. The bonding upper platform 8 is fixedly installed at the bottom of the upper moving platform 1, and its surface is provided with a mounting platform for installing tooling fixtures to place the upper product with the FPC. Preferably, multiple positioning suction cups 9 are provided on the bonding upper platform 8. These suction cups generate negative pressure through a vacuum generator to firmly adhere the FPC to the surface of the bonding upper platform 8. The positions of the suction cups 9 are optimized according to actual production needs, and are usually distributed near the critical areas of the FPC, such as the four corners or the center, to ensure that the FPC does not shift or warp before bending. Furthermore, the design of the bonding upper platform 8 also considers a modular concept, facilitating the replacement of the corresponding suction cup layout according to different product specifications.

[0023] The bending mechanism 4 is located above the bonding platform 8, and its main components include a bending Y-axis 5, a bending pivot 6, and a bending plate 7. The bending Y-axis 5 includes a Y-axis motion structure, which can be a cylinder or a linear motor, etc., to drive the bending pivot at its end to move back and forth. The bending pivot 6 is equipped with a bending plate 7 at its end. Here, the bending pivot 6 can be set at a certain angle and maintain a certain downward bending angle. The bending plate 7 is located on the upper side of the PFC. When the bending Y-axis moves inward, it can drive the bending plate 7 to move inward synchronously. Since the bending plate 7 is preset to a downward tilt angle through the bending pivot 6, it can drive the FPC downward to bend to a first preset angle from top to bottom. When there are two bonding platforms, the length of the bending plate 7 extends above the two bonding platforms 11, and two FPCs can be bent simultaneously. The tilt angle of the bending plate 7 can be controlled by adjusting the angle of the bending pivot 6 on the bending Y-axis to meet different bending requirements.

[0024] Combination Figure 1 and Figure 3As shown, the lower moving platform 2 is located below the upper moving platform 1 and mainly includes an alignment platform 10, a bonding lower platform 11, a positioning mechanism 12, and a gripper mechanism 15. The alignment platform 10 ensures the position of the bonding lower platform 11, matching it with the bonding upper platform 8. This matching can be achieved through coordinate positioning using existing control programs or alignment using existing vision mechanisms. The alignment platform 10 has two bonding lower platforms 11 arranged in parallel, enabling simultaneous bending and bonding operations on two sets of FPCs. Each bonding lower platform 11 has a positioning groove on its surface for placing the lower product. The shape and size of the lower product must match the positioning groove to ensure stability during bonding. Furthermore, tooling fixtures are detachably mounted on the bonding lower platform 11. These fixtures feature a modular design and can be replaced via a quick-locking device. This design significantly improves the flexibility of the equipment, allowing it to adapt to the processing needs of products with different specifications.

[0025] Combination Figure 3 As shown, the positioning mechanism 12 is located on the outside of the lower platform 11. Its main components include a telescopic cylinder 13, a positioning plate 14, and a third lifting device 18. The telescopic cylinder 13 is fixed to the side of the alignment platform 10, and its piston rod is connected to the positioning plate 14. When the telescopic cylinder 13 receives a signal from the control system, the piston rod pushes the positioning plate 14 to move horizontally, which is suitable for bending the FPC inward to a first preset angle and then bending it to a second preset angle. The specific value of the second preset angle is also set according to the product requirements. For example, the FPC can be bent to 90°. The third lifting device 18 can be set as a lifting cylinder, which is used to drive the positioning mechanism 12 to rise to a preset height before positioning to bend and position the FPC. After the gripper mechanism 15 grips the FPC, the positioning mechanism 12 cancels the positioning of the FPC, and the third lifting device 18 drives the positioning mechanism 12 to reset, preparing for the next operation.

[0026] The gripper mechanism 15 is located below the lower platform 11, and its main components include two FPC grippers 16 and a second lifting mechanism 17. The two FPC grippers 16 are each driven by an independent micro-cylinder for gripping the FPC from below. The inner surface of the FPC grippers 16 is designed with anti-slip textures to increase friction and ensure that the FPC does not slip during gripping. The second lifting mechanism 17 can be configured as a lifting cylinder and is located at the bottom of the alignment platform 10. When the FPC is at a second preset angle, the control system sends a command to cause the second lifting mechanism to raise the gripper mechanism 15 to grip the FPC. Subsequently, the second lifting mechanism 17 descends synchronously with the first lifting mechanism 3, pulling the FPC to a position for bonding with the lower product.

[0027] In actual operation, the FPC bending and bonding mechanism operates as follows: S1: Place the FPC or a product with an FPC on the surface of the bonding platform 8. S2: The control system sends a command to activate the first lifting mechanism 3, causing the upper moving platform 1 to descend to a predetermined height. S3: The bending mechanism 4 starts working, causing the bending shaft 6 to move inward, and the bending plate 7 acts on the outside of the FPC, bending the FPC downward to the first preset angle. S4: The positioning mechanism 12 is activated, and the third lifting device 18 drives the telescopic cylinder 13 to rise to the preset height. The telescopic cylinder 13 pushes the positioning plate 14 to move inward, continuing to bend the FPC to the second preset angle. S5: The gripper mechanism 15 is activated, and the second lifting mechanism 17 drives the gripper mechanism 15 to rise. The two FPC grippers 16 grip the FPC from below, and then the telescopic cylinder 13 reverses its movement, causing the positioning plate 14 to cancel its positioning of the FPC, and the third lifting mechanism 18 drives the positioning mechanism to reset. S6: The second lifting mechanism 17 descends synchronously with the first lifting mechanism 3, pulling the FPC to a position where it fits and connects with the lower product. Throughout the process, the control system monitors the operating status of each mechanism in real time and adjusts parameters based on feedback information to ensure the accuracy and stability of the operation.

[0028] This invention, through its structure and operating principle, achieves automated bending and bonding operations for FPCs, significantly improving production efficiency and product quality. In particular, the dual-station design allows the equipment to process two sets of FPCs simultaneously, further enhancing processing capacity. Furthermore, the modular design of each mechanism facilitates maintenance and replacement, reducing equipment operating costs.
