Description

Technical Field

[0001] This utility model relates to the field of patch spring assembly technology, and in particular to a patch spring auxiliary clamping device that is easy to assemble. Background Technology

[0002] A "surface mount spring" is a miniature elastic metal component designed specifically for surface mount technology (SMT). It is widely used on circuit boards of high-density electronic products such as consumer electronics, communication equipment, automotive electronics, and medical instruments to achieve functions such as electrical connection, grounding, shielding, spring contact, and battery contact.

[0003] In existing assembly processes, the spring is typically picked up by an assembly worker and placed on the PCB board. This method suffers from problems such as low efficiency, easy damage to the spring, inaccurate positioning, inconsistent contact force, and easy fatigue.

[0004] Therefore, a new auxiliary clamping device for surface-mount springs has been developed that can automatically pick up surface-mount springs and place them on PCB boards, saving manpower and improving production efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing chip spring assembly methods, which typically involve assembly personnel grabbing the chip springs and placing them on the PCB board, resulting in low efficiency, easy damage to the springs, inaccurate positioning, inconsistent contact force, and easy fatigue, this utility model provides an auxiliary clamping device for chip springs that can automatically grab and place them on the PCB board, saving manpower and improving production efficiency.

[0006] An easy-to-assemble patch spring auxiliary clamping device includes a support frame, a first rodless cylinder, a second rodless cylinder, a guide rod, a first sliding block, and a clamping assembly. Multiple support frames are provided, with a first rodless cylinder connected between the upper parts of two adjacent support frames. A second rodless cylinder is connected between the sliders of the first rodless cylinders. A guide rod is connected to the second rodless cylinder, and a first sliding block is connected to the slider of the second rodless cylinder. The first sliding block is slidably connected to the guide rod, and a clamping assembly capable of clamping the patch spring is provided on the first sliding block.

[0007] To further explain, the clamping assembly includes an electric actuator, a connector, a slide rail, a first motor, a rotating frame, a second motor, a bidirectional lead screw, a second sliding block, and a clamping block. The electric actuator is connected to the first sliding block, and the connector is connected to the telescopic end of the electric actuator. The slide rail is connected to the lower side of the connector. The first motor is connected to the lower right side of the connector. The rotating frame is connected to the output shaft of the first motor. The rotating frame is rotatably connected to the connector. The second motor is connected to the lower right side of the rotating frame. The bidirectional lead screw is connected to the output shaft of the second motor. The bidirectional lead screw is rotatably connected to the rotating frame. The left and right sides of the bidirectional lead screw are threadedly connected to the second sliding blocks. The second sliding blocks are slidably connected to the rotating frame. A clamping block is connected to the lower side of each second sliding block.

[0008] To further explain, it also includes pulleys. Both the left and right sides of the rotating frame are rotatably connected to pulleys, and the pulleys are rotatably and slidably connected to the slide rails.

[0009] To further explain, limit plates are provided on both the left and right sides of the pulley.

[0010] To further explain, it also includes pressure sensors, with pressure sensors connected to the sides of the clamping blocks that are close to each other.

[0011] To further explain, the first rodless cylinder, the second rodless cylinder, the electric actuator, the first motor, the second motor, the pressure sensor, and the processor are electrically connected through the control module.

[0012] The beneficial effects of this utility model are as follows: By starting the second motor, the bidirectional lead screw is driven to rotate, causing the second sliding blocks to move closer to each other, and the clamping blocks to move closer to each other to clamp the patch spring. After clamping, the rotating frame is rotated to reset, the patch spring is adjusted to a vertical state, and then the patch spring is transferred and placed in a designated position on the PCB board. This achieves the effect of automatically grabbing the patch spring and placing it on the PCB board, saving manpower and improving production efficiency. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] An easy-to-assemble patch spring-assisted clamping device, such as Figures 1-4 As shown, it includes a support frame 1, a first rodless cylinder 2, a second rodless cylinder 3, a guide rod 4, a first sliding block 5, and a clamping assembly. There are four support frames 1. The upper parts of two adjacent support frames 1 are connected to the first rodless cylinder 2. The sliders of the first rodless cylinder 2 are connected to the second rodless cylinder 3. The guide rod 4 is connected to the second rodless cylinder 3. The slider of the second rodless cylinder 3 is connected to the first sliding block 5. The first sliding block 5 is slidably connected to the guide rod 4. The first sliding block 5 is equipped with a clamping assembly.

[0020] like Figures 1-4 As shown, the clamping assembly includes an electric actuator 6, a connector 7, a slide rail 8, a first motor 9, a rotating frame 10, pulleys 11, a second motor 12, a bidirectional lead screw 13, a second sliding block 14, a clamping block 15, and a pressure sensor 16. The electric actuator 6 is connected to the first sliding block 5. The connector 7 is connected to the telescopic end of the electric actuator 6. The slide rail 8 is connected to the lower side of the connector 7. The first motor 9 is connected to the lower right side of the connector 7. The rotating frame 10 is connected to the output shaft of the first motor 9. The rotating frame 10 is rotatably connected to the connector 7. Pulleys 11 are rotatably connected to the upper left and right sides of the rotating frame 10. Limiting plates are provided on both sides of the pulleys 11 to prevent displacement. All 11 are rotatably and slidably connected to the slide rail 8. The lower right side of the rotating frame 10 is connected to the second motor 12. The output shaft of the second motor 12 is connected to the bidirectional lead screw 13. The bidirectional lead screw 13 is rotatably connected to the rotating frame 10. The left and right sides of the bidirectional lead screw 13 are threadedly connected to the second sliding block 14. The second sliding block 14 is slidably connected to the rotating frame 10. The lower side of the second sliding block 14 is connected to the clamping block 15. The clamping blocks 15 are connected to the sides that are close to each other. The first rodless cylinder 2, the second rodless cylinder 3, the electric push rod 6, the first motor 9, the second motor 12, the pressure sensor 16 and the processor are electrically connected through the control module.

[0021] When using this utility model, first place the support frame 1 in the patch spring assembly area, then place the PCB board between the support frames 1, place the feeding box with patch springs in the feeding area, and the processor starts the first rodless cylinder 2 and the second rodless cylinder 3 through the control module to move the first sliding block 5 above the feeding box. Then, the electric actuator 6 is activated, pushing the connector 7 downwards. When the patch spring is placed flat in the feeding box, the processor starts the first motor 9 through the control module, driving the rotating frame 10 to rotate to a horizontal state. The pulley 11 slides on the slide rail 8, improving the stability of the rotating frame 10. Then, the connector 7 continues to move downwards, so that the patch spring is located between the clamping blocks 15. The processor starts the second motor 12 through the control module, driving the bidirectional lead screw 13 to rotate, so that the second sliding blocks 14 move closer to each other, thereby making the clamping blocks 15 move closer to each other to clamp the patch spring. The pressure sensor 16 monitors the pressure on the patch spring in real time, so as to make timely adjustments and avoid damage to the patch spring. After clamping the patch spring, the rotating frame 10 is rotated back to its original position, adjusting the patch spring to a vertical state, and then transferring the patch spring to the designated position on the PCB board. This allows for automatic picking of the patch spring and placing it on the PCB board, saving manpower and improving production efficiency.
