Description

Technical Field

[0001] This application relates to the technical field of PCB board removal, and in particular to a PCB board clamping device. Background Technology

[0002] In the fields of electronics manufacturing and related technologies, the handling and transportation of PCB boards are crucial. With the continuous development of the electronics industry, higher demands are being placed on the efficiency and quality of PCB board processing and handling. Efficient and accurate acquisition and handling of PCB boards have a vital impact on improving the efficiency of the entire production process, reducing costs, and ensuring product quality. It relates to many aspects of electronic equipment, including production cycles and performance stability, and occupies an indispensable position in the development of the electronics manufacturing industry.

[0003] In the PCB board removal process, the industry standard practice is to use vacuum suction cups. This method utilizes the principle of vacuum adsorption, allowing the suction cup to adhere tightly to the PCB board surface, thereby enabling the board to be picked up and moved. This is a common and traditional method of board removal, widely used in many production scenarios.

[0004] However, existing vacuum chuck PCB removal methods have significant drawbacks. They lack positioning mechanisms, making them unsuitable for production scenarios with high positioning requirements. Furthermore, since the vacuum chuck comes into direct contact with the PCB components during operation, there is a high risk of damage to the components on the PCB during the suction and placement process, which undoubtedly increases the defect rate and cost in the production process. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this application provides a PCB board clamping device.

[0006] The PCB board clamping device provided in this application adopts the following technical solution:

[0007] A PCB board clamping device includes a conveying mechanism, a PCB blocking block, a clamping mechanism, and a driving mechanism. The conveying mechanism is used to convey a PCB board to the conveying clamping mechanism. The PCB blocking block is used to position the PCB board, causing it to stop at the output end of the conveying mechanism. The clamping mechanism is located at the output end of the conveying mechanism and includes a flexible electric gripper. The flexible electric gripper has a flexible control box and clamping elements. The flexible control box is used to drive the clamping elements to move closer together to clamp the PCB board or move further apart to release the PCB board. The driving mechanism is used to drive the clamping mechanism to reciprocate vertically and horizontally.

[0008] By adopting the above technical solution, the conveying mechanism can transport PCB boards, and the PCB blocking block can block the PCB board so that it cannot continue to move after reaching the predetermined position to position the PCB board, so that the PCB board stays at the board exit end of the conveying mechanism. The flexible control box of the flexible electric gripper drives the clamping component to move to achieve clamping and releasing of the PCB board. The drive mechanism drives the clamping mechanism to move, avoiding the problems of low positioning accuracy and damage to components caused by vacuum suction cup picking method.

[0009] Optionally, the clamping members are provided with a positioning groove on the side that is close to each other for cooperating with the PCB board, and the positioning groove is provided with chamfers on both sides.

[0010] By adopting the above technical solution, when the PCB board is clamped by the clamping component under the drive of the flexible control box, the clamping component can cooperate with the PCB board through the positioning groove, thereby improving the clamping accuracy. The positioning groove has chamfers on both sides to avoid damaging the PCB board.

[0011] Optionally, the conveying mechanism includes a first frame, a fixed conveying component, a movable conveying component, and a first drive screw. The fixed conveying component is fixedly connected to the first frame, and the movable conveying component is slidably connected to the first frame, either close to or away from the fixed conveying component. The fixed conveying component includes a fixed conveying frame, and the movable conveying component includes a movable conveying frame. Both the fixed and movable conveying components include a conveyor belt structure. The working surface of the conveyor belt structure is lower than the top surface of the fixed conveying frame and the top surface of the movable conveying frame. The working surface of the conveyor belt structure is used to abut against both sides of the bottom surface of the PCB board to convey the PCB board. The first drive screw is rotatably connected to the first frame around its own axis and threadedly connected to the movable conveying frame.

[0012] By adopting the above technical solution, the conveying mechanism can transport PCB boards to the clamping mechanism. The fixed conveying component and the moving conveying component work together to adapt to PCB boards of different sizes. The working surface of the conveyor belt structure is lower than the top surface of the fixed conveying frame and the moving conveying frame, which allows the side walls of the fixed conveying frame and the moving conveying frame to guide and limit the PCB board. The conveyor belt structure abuts against both sides of the bottom surface of the PCB board for conveying, avoiding contact with the PCB component surface, reducing the risk of damaging components, and improving the overall positioning accuracy of the PCB board.

[0013] Optionally, the drive mechanism includes a second frame, a lateral movement component, and a vertical movement component. The lateral movement component includes a lateral sliding table and a second drive screw. The lateral sliding table is slidably connected to the second frame and can reciprocate laterally. The second drive screw is rotatably connected to the second frame and threadedly connected to the lateral sliding table, and the vertical movement component is disposed on the lateral sliding table.

[0014] By adopting the above technical solution, the second drive screw rotates around its own axis, thereby driving the transverse sliding table connected to it to move back and forth on the second frame in the transverse direction, so as to realize the adjustment of the transverse position of the transverse moving component.

[0015] Optionally, the vertical movement component includes an electric track arranged in a vertical direction and a vertical sliding seat that cooperates with the electric track, and the flexible control box is fixedly connected to the vertical sliding seat.

[0016] By adopting the above technical solution, the combination of electric track and vertical sliding seat can enable the vertical sliding seat to drive the flexible control box to move stably in the vertical direction. With the positioning groove of the clamping component, more precise and safe vertical position adjustment of the PCB board can be achieved.

[0017] Optionally, a chain groove is provided on one side of the electric track, and the moving end of the chain groove is connected to the flexible control box.

[0018] By adopting the above technical solution, a chain groove is set on one side of the electric track and the moving end of the chain groove is connected to the flexible control box. This provides a stable path for the arrangement of lines and pneumatic pipes during the vertical movement of the flexible control box, avoids messy lines and pneumatic pipes, reduces the risk of damage to lines and pneumatic pipes due to friction and pulling during movement, and thus ensures the stable and reliable operation of the flexible control box, improving the stability and reliability of the entire PCB board clamping device.

[0019] Optionally, a blocking frame is provided at the second rack, and the PCB blocking block is fixedly connected to the second rack through the blocking frame.

[0020] By adopting the above technical solution, the PCB blocking block can be stably installed on the second frame, ensuring the stability of its positioning of the PCB board and allowing the PCB board to accurately stop at the board exit end of the conveyor mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By positioning the PCB board using PCB blocking blocks and using the flexible control box of the flexible electric gripper to drive the clamping component, the positioning accuracy can be improved, meeting the needs of production scenarios with high positioning requirements.

[0023] 2. The PCB board is held by a flexible electric gripper, which avoids direct contact with the PCB component surface, reduces the risk of damage to the components on the PCB board, and reduces the defect rate and cost in the production process;

[0024] 3. The drive mechanism can drive the clamping mechanism to move back and forth vertically, which can efficiently acquire and process PCB boards and improve the efficiency of the entire production process. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0028] This application discloses a PCB board clamping device.

[0029] like Figure 1 As shown, the PCB board clamping device includes a conveying mechanism, a PCB blocking block 16, a clamping mechanism, and a driving mechanism. The conveying mechanism transports the PCB board 17 to the clamping mechanism. The PCB blocking block 16 positions the PCB board 17 at the output end of the conveying mechanism. The clamping mechanism is located at the output end of the conveying mechanism and clamps or releases the PCB board 17 by driving the clamping member 8 through the flexible control box 7 of the flexible electric gripper. The flexible control of the flexible electric gripper can adapt to PCB boards 17 of different sizes, and the driving mechanism can flexibly adjust the lateral position of the clamping mechanism, thereby improving board removal efficiency and quality.

[0030] like Figure 1 As shown, specifically, the conveying mechanism includes a first frame 1, a fixed conveying component, a moving conveying component, and a first drive screw 4. The first frame 1 provides support and a mounting base for the entire conveying mechanism. It can be welded from steel and has high strength and stability. The fixed conveying component includes a fixed conveying frame 2, which is fixedly connected to the first frame 1. The moving conveying component includes a moving conveying frame 3, which can be slidably connected to the first frame 1, either close to or away from the fixed conveying frame 2. In this embodiment, the first frame 1 is provided with multiple first transverse guide rods 6, and the moving conveying frame 3 is provided with mating holes that cooperate with the first transverse guide rods 6. Through the mutual cooperation between the transverse guide rods and the mating holes, a stable sliding structure is achieved, ensuring that the moving conveying component can slide back and forth laterally.

[0031] Both the stationary and moving conveyor components include a conveyor belt structure 5. The conveyor belt structure 5 is located on two adjacent side walls of the stationary conveyor frame 2 and the moving conveyor frame 3. The conveyor belt structure 5 can consist of a conveyor belt and multiple electrically driven rollers. The conveyor belt is wound around the electrically driven rollers, thus causing the conveyor belt to rotate. The working surface of the conveyor belt structure 5 is lower than the top surfaces of the stationary conveyor frame 2 and the moving conveyor frame 3. This design allows the side walls of the stationary conveyor frame 2 and the moving conveyor frame 3 to guide and limit the movement of the PCB board 17 during transport. The working surface of the conveyor belt structure 5 is used to abut against both sides of the bottom surface of the PCB board 17 for transport.

[0032] The first drive screw 4 is rotatably connected to the first frame 1 and threadedly connected to the movable conveyor frame 3 around its own axis. By rotating the first drive screw 4, the movable conveyor frame 3 can be moved closer to or further away from the fixed conveyor frame 2, thereby adapting to PCB boards 17 of different widths. For ease of control, a first drive motor or a first handle 401 can be set to drive the first drive screw 4 to rotate around its own axis, thereby moving the movable conveyor frame 3.

[0033] The above components are combined in a manner that involves adjusting the distance between the moving conveyor frame 3 and the fixed conveyor frame 2 using the first drive screw 4 to accommodate PCB boards 17 of different sizes. Then, an electric drive roller drives the conveyor belt structure 5 to smoothly transport the PCB board 17 to the output end. The resulting combination achieves stable transport of PCB boards 17 of different sizes, improving the versatility of the conveying mechanism.

[0034] like Figure 1 As shown, the flexible control box 7 and the clamping members 8 of the flexible electric gripper together constitute the clamping mechanism. The flexible control box 7 can be a housing integrating a controller, driver, and sensor. It can be made of aluminum alloy, which has good heat dissipation and protection performance. The function of the flexible control box 7 is to drive the clamping members 8 to move closer together to clamp the PCB board 17 or move further apart to release the PCB board 17. The clamping members 8 can be made of flexible materials such as plastic or rubber, so as to avoid damage to the components on the PCB board 17 when clamping it. The side of the clamping members 8 that moves closer together has a positioning groove 801 for cooperating with the PCB board 17. The positioning groove 801 has chamfers on both sides. The positioning groove 801 ensures that the clamping members 8 accurately clamp the PCB board 17, and the chamfers facilitate the smooth entry of the PCB board 17 into the positioning groove 801. The flexible control box 7 can achieve precise control of the clamping force of the clamping component 8 through pneumatic drive, sensor detection of the feedback of the clamping component 8 and intelligent algorithm, so that the clamping component 8 can adaptively grasp PCB boards 17 of different widths, while avoiding damage to the target object. Since the flexible electric gripper is a commonly used existing device in the art, its structure and algorithm will not be described in detail.

[0035] These components are combined in a logical manner: the flexible control box 7 controls the opening and closing of the clamping component 8 according to received instructions; the positioning groove 801 and the chamfer design make the clamping process more accurate and smooth. The resulting combination effect is the ability to accurately and safely clamp and release the PCB board 17.

[0036] like Figure 1 As shown, the drive mechanism includes a second frame 9, a lateral movement component, and a vertical movement component. The second frame 9 provides support and a mounting base for the entire drive mechanism. It can be a metal frame structure, such as aluminum alloy profiles, which is lightweight and high-strength. The lateral movement component includes a lateral sliding table 10 and a second drive screw 11. The lateral sliding table 10 is slidably connected to the second frame 9, capable of reciprocating laterally. In this embodiment, the second frame 9 is provided with multiple second lateral guide rods 18, and the lateral sliding table 10 is provided with mating grooves that cooperate with the second lateral guide rods 18. Through the mutual cooperation between the second lateral guide rods 18 and the mating grooves, a stable sliding structure is achieved, ensuring that the lateral sliding table 10 can slide laterally reciprocally. The second drive screw 11 is rotatably connected to the second frame 9 around its own axis and is threadedly connected to the lateral sliding table 10. By rotating the second drive screw 11, the lateral sliding table 10 can move laterally on the second frame 9. For ease of control, a second drive motor or a second handle 1101 can be installed to drive the second drive screw 11 to rotate around its own axis, thereby moving the transverse sliding table 10. For automatic control, in addition to the second drive motor, a distance sensor pointing towards the moving conveyor 3 can be installed at the fixed conveyor 2 to detect the distance between the fixed conveyor 2 and the moving conveyor 3. A control component is also installed; this component receives the data detected by the distance sensor and controls the second drive motor to adjust the position of the transverse sliding table 10 laterally, ensuring that the clamping mechanism is positioned centrally between the fixed conveyor 2 and the moving conveyor 3, thus ensuring accurate alignment of the PCB board 17 during clamping.

[0037] like Figure 1As shown, the vertical moving component is mounted on the horizontal sliding table 10. The vertical moving component includes an electric track 12 arranged vertically and a vertical sliding seat 13 that cooperates with the electric track 12. When the electric track 12 is working, the vertical sliding seat 13 can slide up and down along the electric track 12. The flexible control box 7 is fixedly connected to the vertical sliding seat 13, thus enabling the clamping mechanism to move vertically and horizontally via a drive mechanism. A chain groove 14 is provided on one side of the electric track 12. The moving end of the chain groove 14 is connected to the flexible control box 7. The chain groove 14 provides a stable path for the wiring and pneumatic pipes during the vertical movement of the flexible control box 7, avoiding messy wiring and pneumatic pipes and reducing the risk of damage to the wiring and pneumatic pipes due to friction and pulling during movement. This ensures the stable and reliable operation of the flexible control box 7 and improves the stability and reliability of the entire PCB board 17 clamping device.

[0038] like Figure 1 As shown, a blocking frame 15 is provided at the second frame 9, and the PCB blocking block 16 is fixedly connected to the second frame 9 through the blocking frame 15. The blocking frame 15 can be made of metal rod or plate, and its function is to fix the PCB blocking block 16. The PCB blocking block 16 can be made of elastic materials such as rubber or plastic, so that it can play a buffering role when blocking the PCB board 17 and avoid damage to the PCB board 17.

[0039] The implementation principle of the PCB board clamping device in this embodiment is as follows: The PCB board clamping device in this embodiment stably transports the PCB board 17 through the conveying mechanism, the PCB blocking block 16 accurately determines the board picking position, the flexible electric claw safely and accurately clamps and releases the PCB board 17, and the drive mechanism flexibly adjusts the position of the clamping mechanism. Compared with the traditional vacuum suction cup board picking method, it improves the positioning accuracy of board picking, avoids damage to the components on the PCB board 17, reduces the defect rate and cost in the production process, and improves production efficiency and product quality. It is a significant improvement over the prior art.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
