Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to an FPC bonding device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are circuit boards made of flexible substrates (such as polyimide or polyester film). They are characterized by being thin, flexible, and heat-resistant, and are widely used in fields with high requirements for space and flexibility, such as smartphones, wearable devices, and automotive electronics. In the FPC production process, multiple FPCs need to be glued and assembled to enable data transmission in multiple locations.

[0003] Currently, a Chinese patent application with authorization announcement number CN 222448631 U and authorization announcement date of February 11, 2025, proposes an automatic welding mechanism for backlight FPC of liquid crystal display module, which includes: a feeding device, a welding alignment device and a unloading device. The feeding device includes a feeding robot; the welding alignment device includes a positioning seat, a positioning component and a welding component, with the positioning component disposed on the positioning seat; the welding component is disposed above the positioning seat; and the unloading device includes an unloading robot.

[0004] In use, the loading robot is used to transfer the LCD display module to the positioning seat, the positioning component is used to clamp and position the LCD display module, and the welding component is used to automatically weld the backlight FPC of the LCD display module on the positioning seat; the unloading robot is used to unload the LCD display module after the welding operation is completed.

[0005] The aforementioned technologies require a robotic arm to place the FPC to be welded at a specific angle on the positioning seat before the welding assembly can be controlled to weld the FPC. This limits the device to welding only FPCs at specific welding positions, thus restricting its application range. Utility Model Content

[0006] In order to enable FPC welding and positioning at various angles during the FPC welding process and improve the versatility of the device, this utility model provides an FPC bonding device.

[0007] This utility model provides an FPC bonding device, which adopts the following technical solution:

[0008] An FPC bonding device includes a feeding mechanism and a conveying mechanism. The conveying mechanism includes a conveying guide rail and a positioning plate. The feeding mechanism includes a unloading platform, a moving component, and a gripping component. The moving component includes a robotic arm, a rotating component, and a lifting component. One end of the robotic arm is fixedly mounted on the edge of the guide rail. The rotating component is fixedly mounted on the other end of the robotic arm. The lifting component is rotatably mounted on the rotating component. The gripping component is fixedly mounted on the lower end of the lifting component and is used to grip materials.

[0009] By adopting the above technical solution, when the bonding device is working, firstly, the robotic arm moves the rotating component, lifting component, and gripping component to above the unloading platform. Secondly, the rotating component controls the gripping component to adjust its direction, and the lifting component controls the gripping component to grip the FPC on the unloading platform. Thirdly, after the FPC is gripped, it is placed on the positioning plate in the conveying mechanism with the cooperation of the rotating component, lifting component, and robotic arm. Finally, the positioning plate moves the FPC to the next processing position under the conveying of the guide rail. In this way, through the cooperation of the rotating component and the lifting component, the angle of gripping the FPC and the angle of placement on the positioning plate can be adjusted, allowing for the gripping of FPCs of various shapes and angles, thus increasing the applicability of the bonding device.

[0010] Optionally, the lifting assembly includes a lead screw, a nut, and a first driving member. The nut is rotatably mounted in the robotic arm, and the lead screw passes through the nut, with the lead screw threaded into the nut. The first driving member is used to drive the nut to rotate. The rotating assembly includes a second driving member and a limiting ring. The limiting ring is sleeved on the outside of the lead screw, and a limiting block is fixedly provided on the inner circumferential surface of the limiting ring. A sliding groove is provided on the outer circumferential surface of the lead screw, and the sliding groove is arranged along the axial direction of the lead screw. The limiting block is slidably disposed in the sliding groove. The second driving member is used to drive the limiting ring to rotate.

[0011] By adopting the above technical solution, when the first driving component drives the nut to rotate, the limiting ring is fixedly set. The nut, in conjunction with the thread, can drive the lead screw to move in the vertical direction. At this time, the limiting block set on the inner circumference of the limiting ring slides in the groove on the outer circumference of the lead screw, so that when the nut drives the lead screw to rotate, the lead screw can slide in the vertical direction without rotating, thereby driving the gripping component to rise and fall without changing the rotation of the gripping component. When the second driving component drives the limiting ring to rotate, the first driving component drives the nut and the limiting ring to rotate synchronously, so that the lead screw rotates under the synchronous drive of the limiting ring and the nut, thereby adjusting the angle of the gripping component without changing the lifting and lowering position of the gripping component. In this way, by setting the rotating component and the lifting component together, the lifting and lowering of the gripping component and the rotation angle of the gripping component can be controlled simultaneously. At the same time, setting the lifting component and the rotating component together can also save installation space and improve space utilization.

[0012] Optionally, a vision inspection component is also included, which includes a protective plate and a lens module. The lens module is fixedly mounted on the guide rail and is positioned facing the gripping component. The protective plate is positioned above the lens module and is used to protect the lens module from above.

[0013] By adopting the above technical solution, the gripping component, under the control of the lifting and rotating components, can grasp the FPC and move it. However, since each FPC has a certain difference in shape and position, after the gripping component grasps the FPC, the robotic arm will move the rotating, lifting, and gripping components together to above the lens module. Subsequently, the lens module will perform position detection on the currently gripped FPC. The detection result will be fed back to the rotating component to adjust the angle of the FPC, so that the position of the FPC is adjusted before being placed on the positioning plate, improving the accuracy of the FPC being placed on the positioning plate. In this way, the lens module can perform position calibration every time the gripping component grasps the FPC, improving the accuracy of the FPC being placed on the positioning plate, while the protective plate can reduce the probability of objects falling on the lens module and causing damage to the lens module.

[0014] Optionally, the guide rail is provided with a lifting component and a clamping component. The clamping component is fixedly disposed at the edge of the guide rail, and the lifting component is fixedly disposed between the guide rails. The lifting component and the clamping component are correspondingly disposed. The lifting component is used to lift the positioning plate upward. When the positioning plate is lifted by the lifting component, the positioning plate is clamped between the lifting component and the clamping component for positioning.

[0015] By adopting the above technical solution, before the gripping component places the FPC on the positioning plate, the positioning plate moves along the guide rail to a specific position. After the positioning plate moves to the specific position, the lifting component lifts the positioning plate from below. Once lifted, the positioning plate is clamped between the lifting component and the clamping member, fixing the positioning plate in its current position. Subsequently, the moving component, in conjunction with the gripping component, places the FPC on the positioning plate. This design, using the lifting component and clamping member, secures the positioning plate, increasing its stability during FPC placement and ensuring more precise positioning of the FPC on the positioning plate.

[0016] Optionally, a positioning cylinder is also provided on the guide rail. The positioning cylinder is located behind the lifting assembly along the conveying direction. The piston rod of the positioning cylinder extends toward the lifting assembly, and an elastic element is also provided on the piston rod of the positioning cylinder. The elastic element contacts the positioning plate for positioning.

[0017] By adopting the above technical solution, when the positioning plate moves to a specific position, its edge abuts against the elastic element, gradually compressing and moving the elastic element to its limit position. If the positioning plate's position is not precise enough, the piston rod of the positioning cylinder will extend to adjust the position of the positioning plate, allowing it to stop more accurately in the specific position. After the positioning plate is lifted by the lifting assembly, the elastic element will pop out and move below the positioning plate, so that after the lifting assembly falls, the positioning plate can press on the elastic element and continue moving along the guide rail. In this way, the positioning cylinder can adjust the position of the positioning plate, allowing it to land more accurately in the specific position; the elastic element can act as a buffer, reducing the impact when the positioning plate abuts against the positioning cylinder during movement, and increasing the service life of the components.

[0018] Optionally, the positioning plate is provided with multiple positioning holes, which are connected to an external air source.

[0019] By adopting the above technical solution, the positioning hole is connected to an external negative pressure air source. When the FPC is placed on the positioning plate, the FPC will be attracted to the positioning hole, which makes the FPC more stable on the positioning plate and further improves the accuracy of the FPC position.

[0020] Optionally, the gripping component includes a pressure plate, a valve, and an air supply pipe. The downward-facing end face of the pressure plate is provided with multiple adsorption holes, all of which are connected to the valve. The valve is connected to an external air source through the air supply pipe.

[0021] By adopting the above technical solution, when the gripping component grips the FPC, the pressure plate is pressed firmly above the FPC under the control of the rotating and lifting components. Then, the valve opens, and the external negative pressure air source connects with the adsorption holes on the pressure plate, adsorbing the FPC onto the bottom surface of the pressure plate. Subsequently, the FPC moves together with the gripping component, from the unloading platform to the positioning plate. This method of fixing and gripping the FPC through negative pressure adsorption means that when the FPC needs to be fixed, simply opening the valve secures it; when the FPC needs to be released, closing the valve releases it. Negative pressure adsorption is more suitable for gripping FPCs.

[0022] Optionally, both the pressure plate and the positioning plate are flexibly configured.

[0023] By adopting the above technical solution, since the FPC carries circuit components and is relatively fragile, setting the end face in contact with the FPC as a flexible structure when grasping and placing the FPC can play a certain protective role, reduce the probability of damage during the movement of the FPC, and thus improve the yield of the FPC.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0025] By integrating the rotating and lifting components in the moving assembly, and through the ingenious cooperation of structures such as lead screws, nuts, and limit rings, independent control of the gripping component in both lifting and rotating motion modes is achieved, reducing the space occupied by the device. At the same time, the angle of the gripping component can be adjusted without changing the lifting position, adapting to gripping FPCs of different shapes and angles, thus improving the applicability of the device.

[0026] By setting up a vision inspection component on the guide rail and using a lens module to detect the position of the captured FPC, and adjusting the angle and position of the FPC through feedback, the position and angle of the FPC can be corrected in real time, so as to place the FPC more accurately on the positioning plate and reduce the error of the placement position.

[0027] A lifting assembly and a clamping component are installed on the guide rail. The lifting assembly lifts the positioning plate and clamps it between the lifting assembly and the clamping component to fix the positioning plate. At the same time, a cylinder and an elastic component are used to adjust the position of the positioning plate, which improves the accuracy of the positioning plate's movement and the processing precision of the FPC.

[0028] The gripping components and positioning plates employ negative pressure adsorption technology, combined with flexible material design, to achieve stable gripping and protection of the FPC. The FPC is fixed through adsorption holes, reducing the FPC's detachment and displacement during gripping. The flexible structure of the pressure plate and positioning plate reduces mechanical stress when in contact with the FPC, lowering the risk of damage to the FPC during gripping and placement.

Detailed Implementation

[0035] The following combination Figures 1 to 5 The present invention will be described in further detail below.

[0036] This utility model discloses an FPC bonding device. (Refer to...) Figures 1 to 3An FPC bonding device mainly includes a feeding mechanism 100 and a conveying mechanism 200. The feeding mechanism 100 includes a discharging platform 110, a moving component 300, and a gripping component 400. The conveying mechanism 200 includes a guide rail 210 and a positioning plate 220. The discharging platform 110 is mounted on a support frame on one side of the guide rail 210. When the FPC bonding device is working, firstly, the guide rail 210 moves the positioning plate 220 to a specific position on the guide rail 210. Secondly, the moving component 300 controls the gripping component 400 to perform a set action to discharge the plate 220 from the discharging platform 110. As the FPC moves onto the positioning plate 220, the moving component 300 controls the gripping component 400 to move. First, the gripping component 400 moves above the unloading table 110. Then, the gripping component 400 moves downward and picks up the FPC from the unloading table 110. Next, the gripping component 400 moves according to the set action and moves the FPC above the positioning plate 220. Finally, the gripping component 400 moves downward and places the FPC on the positioning plate 220. The gripping component 400 releases the FPC and moves back to its original position, completing the movement and positioning of the FPC.

[0037] Reference Figure 1 The guide rail 210 includes a bracket and a conveyor belt. The bracket serves as the support structure for the entire device and is located at the bottom. The conveyor belt is located on the inner side of the bracket. When the positioning plate 220 is placed on the conveyor belt, the conveyor belt can drive the positioning plate 220 to move along the direction of the guide rail 210.

[0038] Reference Figure 3 To ensure that the positioning plate 220 can stop at a specific position when moving on the guide rail 210, a positioning cylinder 250 is installed inside the bracket. The positioning cylinder 250 is horizontally set and fixedly installed between the brackets. When the positioning plate 220 moves to the position of the positioning cylinder 250, the positioning plate 220 will abut against the piston rod of the positioning cylinder 250 to complete the positioning. In order to make the stopping position of the positioning plate 220 more accurate, when the piston rod of the positioning cylinder 250 extends, it can push the positioning cylinder 250 to move along the direction of the guide rail 210 to adjust the position of the positioning plate 220.

[0039] Reference Figure 3 In order to reduce the impact of the positioning plate 220 against the positioning cylinder 250, an elastic element 251 is provided at the end of the piston rod of the positioning cylinder 250. In this embodiment, the elastic element 251 is provided with a spring and a sleeve. The sleeve is fitted on the piston rod and the spring is placed inside the sleeve, so that one end of the spring abuts against the end of the piston rod and the other end abuts against the inside of the sleeve. In this way, when the positioning plate 220 abuts against the positioning cylinder 250, it will first abut against the sleeve and compress the spring for buffering.

[0040] Reference Figure 3To ensure the stability of the positioning plate 220 when the gripping component 400 places the FPC on it, the guide rail 210 is also equipped with a lifting component 230 and a clamping component 240. The clamping component 240 is fixedly mounted on the bracket of the guide rail 210, and the lifting component 230 is fixedly mounted between the brackets of the guide rail 210. The lifting component 230 and the clamping component 240 are correspondingly arranged. In this embodiment, the positioning component includes a cylinder and an abutment plate. The cylinder is vertically arranged with the piston rod pointing upwards, and the abutment plate is fixedly mounted on the end of the piston rod. When the cylinder extends, it can lift the abutment plate upward, and the abutment plate will lift the positioning plate 220 from below. When the positioning plate 220 is lifted by the abutment plate, the positioning plate 220 is clamped between the abutment plate and the clamping member 240 to fix the positioning plate 220. After the lifting component 230 lifts the positioning plate 220, the elastic member 251 is released and springs back to its original position below the positioning plate 220. After the lifting component 230 falls, the positioning plate 220 presses on the elastic member 251 and continues to move along the guide rail 210.

[0041] Reference Figure 2 In order to prevent the FPC from moving when it is placed on the positioning plate 220 and to maintain the stability of the FPC on the positioning plate 220, the positioning plate 220 is provided with multiple positioning holes 221. The positioning holes 221 are connected to an external negative pressure air source, and the FPC on the positioning plate 220 can be adsorbed and fixed by negative pressure adsorption.

[0042] Reference Figure 1 The moving component 300 includes a robotic arm 310, a rotating component 500, and a lifting component 600. One end of the robotic arm 310 is fixedly mounted on the edge of the bracket of the guide rail 210. The rotating component 500 is fixedly mounted on the other end of the robotic arm 310. The lifting component 600 is rotatably mounted on the rotating component 500. The gripping component 400 is fixedly mounted below the lifting component 600 and is used to grip materials.

[0043] Reference Figures 3 to 5To reduce the installation space of the lifting assembly 600 and the rotating assembly 500, in this embodiment, the lifting assembly 600 and the rotating assembly 500 are integrated into one structure. Specifically, the lifting assembly 600 includes a lead screw 610, a nut 620, and a first driving member 630. The nut 620 is rotatably mounted in the robotic arm 310, and the lead screw 610 passes through the nut 620. The lead screw 610 and the nut 620 are threaded together. The first driving member 630 is used to drive the nut 620 to rotate. The rotating assembly 500 includes a second driving member 510 and a limiting ring 520. The limiting ring 520 is sleeved on the outside of the lead screw 610. A limiting block 521 is fixedly provided on the inner circumferential surface of the limiting ring 520. A sliding groove 611 is provided on the outer circumferential surface of the lead screw 610. The sliding groove 611 is arranged along the axial direction of the lead screw 610. The limiting block 521 is slidably disposed in the sliding groove 611. The second driving member 510 is used to drive the limiting ring 520 to rotate.

[0044] The nut 620 and the limiting ring 520 are rotatably mounted at the end of the robotic arm 310 via a rotating bearing and a bearing seat. The lead screw 610 passes through the nut 620 and the limiting ring 520. The nut 620 and the limiting ring 520 can rotate together to adjust the height of the lead screw 610 without changing its height. When the nut 620 rotates but the limiting ring 520 does not rotate, the lifting and lowering of the lead screw 610 can be controlled without the lead screw 610 rotating.

[0045] In this embodiment, both the first driving component 630 and the second driving component 510 are motors, and the first driving component 630 and the nut 620 are driven by bevel gears. In other embodiments, conventional transmission methods such as chains, belts, and spur gears can be used.

[0046] Reference Figure 4 The gripping component 400 is fixedly installed at the bottom of the lead screw 610. The gripping component 400 includes a pressure plate 410, a valve 420, and an air supply pipe 430. The upward-facing end face of the pressure plate 410 is fixedly connected to the lead screw 610, and the downward-facing end face of the pressure plate 410 is provided with multiple adsorption holes 411. The valve 420 is fixedly installed on the pressure plate 410 to control the opening and closing of the adsorption holes 411. All adsorption holes 411 are connected to the valve 420. The valve 420 is connected to an external negative pressure air source through the air supply pipe 430. When the valve 420 is open, the external negative pressure air source is connected to the adsorption holes 411, which can adsorb the FPC onto the bottom of the pressure plate 410. When the valve 420 is closed, the external negative pressure air source cannot adsorb the FPC onto the bottom of the pressure plate 410 through the adsorption holes 411, and the FPC can fall off the pressure plate 410.

[0047] In this embodiment, in order to reduce the mechanical stress when the pressure plate 410 and the positioning plate 220 come into contact with the FPC, a rubber layer is provided on the end face of the pressure plate 410 and the positioning plate 220 that comes into contact with the FPC.

[0048] Reference Figure 3 To improve the accuracy of FPC placement, a vision inspection component 700 is also installed on the guide rail 210. The vision inspection component 700 includes a protective plate 720 and a lens module 710. The lens module 710 is fixedly mounted on the guide rail 210 and faces the gripping component 400. The protective plate 720 is positioned above the lens module 710 to protect it. After the gripping component 400 grips the FPC, the robotic arm 310 will drive the rotating component 500, the lifting component 600, and the gripping component 400 to move together above the lens module 710. Subsequently, the lens module 710 will perform position detection on the currently gripped FPC. The detection result will be fed back to the rotating component 500 to adjust the angle of the FPC, so that the position of the FPC is adjusted before being placed on the positioning plate 220, thereby improving the accuracy of the FPC being placed on the positioning plate 220.

[0049] The implementation principle of the FPC bonding device in this embodiment is as follows: First, the positioning plate 220 moves along the guide rail 210. After the positioning plate 220 moves to a specific position, it abuts against the positioning cylinder 250. Then, the lifting component 230 lifts the positioning plate 220 and clamps it between the abutment plate and the clamping member 240, thus fixing the positioning plate 220. At the same time, the robotic arm 310 drives the gripping component 400 to move above the unloading plate. Then, the gripping component 400 descends, and the valve 420 opens. The pressure plate 410 holds the FPC at the bottom. Then, the robotic arm 310, lifting assembly 600, and rotating assembly 500 work together to move the FPC above the lens module 710. The position of the FPC is detected and adjusted. After the adjustment is completed, the robotic arm 310, lifting assembly 600, and rotating assembly 500 work together to place the FPC at a specific angle on the positioning plate 220. Finally, the lifting assembly 230 descends, and the positioning plate 220 falls on the guide rail 210, which drives the FPC to the next processing position for processing.

[0050] In summary, this application integrates the rotating component 500 and the lifting component 600 together. Through the ingenious cooperation of the lead screw 610, nut 620, and limit ring 520, the gripping component 400 can be independently controlled in both lifting and rotating motion modes, reducing the space occupied by the device. At the same time, the angle of the gripping component 400 can be adjusted without changing the lifting position, and the FPC can be placed at a set angle to adapt to different gripping and placement angles. A vision detection component 700 is set on the guide rail 210 to detect the position of the gripped FPC and adjust the angle and position of the FPC through feedback. The position and angle of the FPC can be corrected in real time, and the FPC can be placed on the positioning plate 220 more accurately, reducing the error in placement position.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
