Specifically, during the clamping process, the rotary wheel needs to be manually rotated to drive the clamping device to clamp the circuit board, increasing manual operation steps, extending clamping time, and thus reducing the efficiency of assembly line operations.
[0004] Therefore, a multi-station circuit board wire bonding fixture that can automatically clamp is needed. Utility Model Content
[0005] In order to overcome the shortcomings of the patent, which requires manual rotation of the rotating wheel to drive the clamping device to clamp the circuit board during the clamping process, increasing the manual operation steps, extending the clamping time, and thus reducing the efficiency of the assembly line operation, the purpose of this utility model is to provide a multi-station circuit board wire bonding fixture that can automatically clamp.
[0006] Technical solution: A multi-station circuit board wire bonding fixture includes a base, a support base, a servo motor, a turntable, a placement seat, and a limiting plate. The support base is mounted on the outside of the support base, and the servo motor is mounted on the top of the support base. The output shaft of the servo motor is clamped to the turntable. Multiple placement seats are evenly spaced on the top of the turntable. Sliding grooves are opened on the left and right sides of the placement seats. A limiting plate is fixedly connected to the rear side of the placement seats. The fixture also includes a clamping plate, a fixed seat, and an elastic element. The clamping plate is slidably arranged in two sliding grooves. Multiple fixed seats are mounted on the bottom of the turntable, and an elastic element connects the fixed seat and the clamping plate.
[0007] As an improvement to the above solution, it also includes a guide plate, a first mounting base and a first roller. The guide plate is fixedly connected to the top of the base, and the first mounting base is fixedly connected to the lower rear side of the clamping plate. The first roller is rotatably mounted on the first mounting base and can contact the guide plate.
[0008] As an improvement to the above solution, it also includes a pressing plate and a limiting seat. The pressing plate is fixedly connected to the top of the base, and multiple limiting seats are evenly spaced and slidably arranged on the turntable. The pressing plate can press the limiting seats to move upward.
[0009] As an improvement to the above solution, it also includes a second mounting base and a second roller. A guide groove is provided at the bottom of the turntable, and multiple second mounting bases are evenly spaced on the top of the base. The second roller is rotatably mounted on the second mounting base, and the second roller maintains constant contact with the guide groove.
[0010] As an improvement to the above solution, multiple anti-slip grooves are provided on the limiting plate and clamping plate.

[0012] As an improvement to the above solution, the contact surface between the limit seat and the circuit board is an inclined surface.
[0013] As an improvement to the above solution, the second roller is made of rubber.
[0014] Compared with the prior art, this utility model provides a multi-station circuit board wire bonding fixture, which has the following advantages: 1. By loosening the clamping plate, the elastic element rebounds and pushes the clamping plate to move inward, automatically clamping the circuit board, eliminating the manual fixing step, shortening the clamping time, and improving the efficiency of assembly line operation.
[0015] 2. When the turntable rotates, the first mounting base slides along the guide plate, pushing the clamping plate outward, automatically releasing the soldered circuit board. The operator can then remove the soldered circuit board and place in the new circuit board to be soldered, improving the level of automation and shortening the material change time.
[0016] 3. As the turntable rotates, the extrusion plate uses an inclined plane to push the limit seat upward. The movement of the limit seat extrudes the circuit board, centered the circuit board, and thus improves the precision of the welding.
[0017] 4. The turntable contacts the second roller at its edge, and the turntable rotates, causing the second roller to rotate synchronously. This rotation of the second roller limits the deflection of the turntable, ensuring its stability during rotation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: A multi-station circuit board wire bonding fixture, please refer to... Figures 1-7The device includes a base 1, a support base 2, a servo motor 3, a turntable 4, a placement seat 5, and a limiting plate 6. The base 1 is installed on the outside of the support base 2, and the servo motor 3 is installed on the top of the support base 2. The output shaft of the servo motor 3 is clamped to the turntable 4. Six placement seats 5 are evenly spaced on the top of the turntable 4. Sliding grooves 501 are opened on the left and right sides of the placement seats 5. The limiting plate 6 is fixedly connected to the rear side of the placement seats 5. The two sliding grooves 501 are slidably set with a clamping plate 7. Six fixed seats 8 are installed at the bottom of the turntable 4. Elastic elements 801 are connected between the fixed seats 8 and the clamping plate 7. Anti-slip grooves 17 are opened on the limiting plate 6 and the clamping plate 7. The anti-slip grooves 17 are used to increase friction and prevent the circuit board from falling off. The bottom of the base 1 is circular to increase the overall stability of the device.
[0028] When soldering the circuit board is required, first pull the clamping plate 7 outward to widen the gap between the limiting plate 6 and the clamping plate 7. The elastic element 801 is stretched accordingly. Then, place the circuit board to be soldered into the area between the limiting plate 6 and the clamping plate 7, ensuring that it is aligned with the reference surface of the placement seat 5. Then, release the clamping plate 7, and the elastic element 801 rebounds, pushing the clamping plate 7 inward to automatically clamp the circuit board, eliminating the manual fixing step, shortening the clamping time, and improving the efficiency of the assembly line operation. Subsequently, the servo motor 3 is started. The output shaft of the servo motor 3 rotates, driving the turntable 4 to rotate intermittently, realizing multi-station cyclic operation. Each station can correspond to different soldering processes. At the current station, the operator or robotic arm uses soldering tools to solder the circuit board. After the soldering is completed, pull the clamping plate 7 outward again to release the clamping of the circuit board, remove the finished product from the placement seat 5, and the turntable 4 rotates to the next station. The above process is repeated for continuous operation.
[0029] Example 2: Based on Example 1, please refer to... Figure 3 , Figure 4 and Figure 5 A guide plate 9 is fixedly connected to the top of the base 1, and a first mounting seat 10 is fixedly connected to the lower rear side of the clamping plate 7. A first roller 11 is rotatably mounted on the first mounting seat 10, and the first roller 11 can contact the guide plate 9.
[0030] After the circuit board at the current workstation is soldered, the servo motor 3 is started. The output shaft of the servo motor 3 rotates, driving the turntable 4 to rotate. When the turntable 4 rotates, the first mounting base 10 slides along the guide plate 9, pushing the clamping plate 7 to move outward, automatically releasing the soldered circuit board. The operator takes out the soldered circuit board and puts in the new circuit board to be soldered, improving the degree of automation and shortening the material change time. When the turntable 4 continues to rotate to the next workstation, the clamping plate 7 automatically springs back and resets under the action of the elastic element 801, re-clamping the newly placed circuit board to ensure the stability of the soldering.
[0031] Please see Figure 6The base 1 is fixedly connected to the top of the extrusion plate 12. The turntable 4 is evenly spaced and slidably provided with six limit seats 13. The extrusion plate 12 can extrude the limit seats 13 to move upward. The contact surface between the limit seats 13 and the circuit board is inclined, so as to extrude the circuit board to move.
[0032] When the output shaft of the servo motor 3 rotates and drives the turntable 4 to rotate, the limit seat 13 rotates accordingly. When the turntable 4 rotates to a specific angle, the limit seat 13 contacts the extrusion plate 12 fixed on the frame. As the turntable 4 continues to rotate, the extrusion plate 12 uses an inclined plane to push the limit seat 13 to move upward. The movement of the limit seat 13 extrudes the circuit board, making the circuit board centered, thereby improving the accuracy of welding.
[0033] Please see Figure 1 and Figure 7 The bottom of the turntable 4 is provided with a guide groove 14, and four second mounting seats 15 are evenly spaced on the top of the base 1. Second rollers 16 are rotatably mounted on the second mounting seats 15. The second rollers 16 maintain constant contact with the guide groove 14. The second rollers 16 are made of rubber. The rubber material effectively absorbs the vibration and noise when the turntable rotates. Compared with metal rollers, the rubber contact surface provides greater friction to prevent the turntable 4 from slipping.
[0034] When the turntable 4 rotates, the guide groove 14 contacts the second roller 16, and the second roller 16 rotates synchronously through friction, so that the rotation of the second roller 16 limits the deflection of the turntable 4 and ensures that it remains stable during rotation.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
