Description

Technical Field

[0001] The present invention relates to the technical field of panel production equipment, and in particular to a bending device for reducing the molding damage rate of FPC products. Background Art

[0002] At present, electronic products have become an indispensable part of people's lives in large numbers. The LED screen of electronic products is generally connected with FPC (flexible circuit board), which is a printed circuit board made of polyimide or polyester film as the substrate with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bending properties, so it has been widely used. In the application process, due to the different internal space layout of the LED screen, the FPC needs to be bent to different degrees during the connection process to meet the space requirements.

[0003] For example, the document with Chinese patent application number 202311775114.9 and publication date 2024.03.22 discloses an FPC folding device and a folding method, including a visual positioning module and a product jig, and a gripper robot and an FPC folding module are provided on one side of the product jig on the product jig; the gripper robot includes a robotic arm and a first gripper, the robotic arm is installed on the other side of the product jig, the first gripper is installed on the robotic arm, and the first gripper is used to cooperate with the robotic arm to clamp the FPC of the product located at the X-direction groove from the product jig and move it to the Y-direction groove to complete the folding and bending of the FPC; the FPC folding module includes a folding mechanism, the folding mechanism includes a multi-axis moving assembly arranged next to the product jig, and a folding piece arranged on the multi-axis moving assembly, and the multi-axis moving assembly is used to drive the folding piece to fold the folded and bent part of the FPC into shape.

[0004] In the above-mentioned document, the FPC product placed in the X-direction groove and the Y-direction groove is bent back by a folding piece. After one bending, it cannot be placed in the groove, so it cannot be bent multiple times in one direction. Multiple bending in the X-direction is only performed by bending from the top to the groove where the FPC product is placed by a folding piece. Since the bottom of the groove is made of hard material, it is easy to cause friction between the bottom of the groove and the FPC product during the bending process, resulting in damage to the bottom of the FPC product, or the FPC product is affected by the bottom during the bending process, so that the bending knife is easily damaged or the bending depth cannot be ensured. In addition, by placing it in the groove, it is limited only in the width direction of the groove and cannot be limited along the up and down directions of the groove depth, which makes it easy for the FPC product to move during the bending process, resulting in poor bending effect. Summary of the invention

[0005] The purpose of the present invention is to provide a bending device and method for reducing the molding damage rate of FPC products, which can perform multiple bends on different positions of the FPC product and effectively avoid damaging the FPC product during the bending process, thereby reducing the molding damage rate of the FPC product.

[0006] To achieve the above-mentioned purpose, a bending device for reducing the molding damage rate of FPC products includes a frame, an upper driving assembly, a lower driving assembly and a workbench, the upper driving assembly is arranged above the workbench, the lower driving assembly is arranged below the workbench, an adsorption device is arranged at the bottom of the workbench, more than two clamping devices and openings are arranged on the workbench along the length direction of the workbench, a limiting assembly is arranged along the width direction of the workbench, the clamping device and the limiting assembly are arranged at intervals, and the opening is arranged from the upper end surface of the workbench to the lower end surface, the upper driving assembly drives the bending blade arranged on the upper driving assembly to move above the opening, and the lower driving assembly drives the soft pad arranged on the lower driving assembly to move below the opening, and the bending blade passes through the opening and abuts against the soft pad to bend the FPC product arranged on the workbench.

[0007] In the above structure, after the FPC product is placed on the workbench, the FPC product is limited in height direction by the clamping device, and limited in horizontal direction by the limiting component, so that the FPC product can be reliably limited to move on the workbench, and at the same time, the FPC product can be adsorbed by the adsorption device arranged at the bottom of the workbench, so that the FPC product is close to the upper end surface of the workbench, and then the clamping device can clamp the FPC product to further stabilize the FPC product on the workbench, and the soft pad is driven by the lower driving component to move to the bottom of the opening, and the bending blade is driven by the upper driving component to move to the top of the opening, so that the bending blade and the soft pad are aligned in the vertical direction, and then the bending blade passes through the opening to directly bend the FPC product. At the same time, during the bending process, the FPC product is made to abut against the soft pad. Since the soft pad has a buffering effect on the bent FPC product, this can prevent the FPC product from being bent too much, thereby avoiding damage to the FPC product during the bending process, and also reduce the friction between the FPC product and the lower driving component, improve the bending effect, and thus reduce the molding damage rate of the FPC product.

[0048] In this embodiment, a bending method for reducing the molding damage rate of FPC products includes the following specific steps: S1 places the FPC product 4 on the workbench, the part of the FPC product 4 to be bent corresponds to the opening, the clamping device limits the FPC product 4 from the upper end of the FPC product 4, and the limiting component limits the width direction of the FPC product 4; S1 includes S11 and S12, S11: placing the FPC product 4 on the fixture 21, so that both ends of the FPC product 4 are sleeved on the limiting pillars 211 and the FPC product 4 is located between the limiting blocks 5; S12: The third pressing rod 33 is driven to rise and detach from the bracket 22 by the third driving motor 32, and then the jig 21 with the FPC product 4 is sleeved on the guide column 23 of the bracket 22, so that the jig 21 is aligned with the bracket 22, and the third driving motor 32 is driven to rotate in the opposite direction to drive the third pressing rod 33 to descend and press the FPC product 4 on the jig 21; S2 drives the transmission device 1 to rotate through the X-direction driving motor 12, thereby driving the Y-direction moving component 1 to move in the X direction to the top of the workbench opening 3, and then drives the Y-direction sliding module 41 through the Y-direction driving motor 45 to drive the Z-direction moving component 1 to move in the Y direction, and further adjusts the position of the Z-direction moving component 1 so that the bending blade 58 set on the Z-direction moving component 1 is aligned with the position to be bent of the FPC product 4 placed on the workbench 2; S3 drives the transmission device 2 to rotate through the X-direction driving motor 2 62, and then drives the Y-direction moving component 2 to move in the X direction to the bottom of the workbench opening 3, and then drives the Y-direction sliding module 2 71 through the Y-direction driving motor 2 75 to drive the Z-direction moving component 2 to move in the Y direction, and further adjusts the position of the Z-direction moving component 2 so that the soft pad 88 set on the Z-direction moving component 2 is aligned with the FPC product 4 to be bent on the workbench 2, and then drives the Z-direction sliding module 2 81 through the Z-direction driving motor 2 84 to drive the Z-direction supporting seat 2 82 to move in the Z direction, so that the soft pad 88 abuts against the FPC product 4 to be bent; S4 drives the bending blade 58 to rotate the angle through the first driving motor 56, so that the bending blade 58 matches the crease at the FPC product 4 to be bent, and then drives the Z-direction sliding module 52 through the Z-direction driving motor 54 to drive the Z-direction support seat 52 to move in the Z direction, thereby driving the bending blade 58 to pass through the opening 3 and abut against the soft pad 88 to bend the FPC product 4 set on the workbench 2 into shape at one time.

[0049] After completing the bending and forming of a FPC product at a position to be bent at an opening of the workbench, S5 continues to move to another opening to bend and form another position to be bent of the FPC product according to steps S2-S4, thereby achieving multiple bending and forming at different positions of the FPC product.

[0050] The working principle of the present invention is as follows: after the FPC product is placed on the workbench, the movement of the FPC product on the workbench is limited by a limit assembly, and at the same time, the FPC product is adsorbed by an adsorption device arranged at the bottom of the workbench, so that the FPC product is close to the upper end surface of the workbench, and then the soft pad is driven to move to the bottom of the opening by the lower driving assembly 02, and at the same time, the bending blade is driven to move to the top of the opening by the upper driving assembly 01, so that the bending blade and the soft pad are aligned in the vertical direction, and then the bending blade passes through the opening to directly bend the FPC product, and at the same time, during the bending process, the FPC product is made to abut against the soft pad. Since the soft pad has a buffering effect on the bent FPC product, this can prevent the FPC product from being bent too much, thereby avoiding damage to the FPC product during the bending process, thereby reducing the molding damage rate of the FPC product.
