[0025] Example

[0026] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a cross-sectional schematic diagram of the present invention. This embodiment provides a pusher clamp, including a top shell 1 and a bottom shell 2. The top shell 1 and the bottom shell 2 cooperate to form a channel for the movement of clamps 3. One end of the top shell 1 has a clamping opening 11, and the bottom shell 2 has an exit opening 21 at the end away from the clamping opening 11. Both the exit opening 21 and the clamping opening 11 are connected to the channel. The bottom shell 2 has a guide slope 24 near the exit opening 21. The guide slope 24 causes the bottom of the bottom shell 2 to gradually thicken from the clamping opening 11 along the exit opening 21. As multiple clamps 3 are inserted into the channel, the first clamp 3 inserted is continuously lifted along the guide slope 24. A flexible V-shaped clamp 22 with an outward opening is provided at the clamping port 21. The flexible V-shaped clamp 22 is used to open the clamp 3. The bottom shell 2 has an inclined slide 23 below the clamping port 11. One end of the inclined slide 23 is connected to the inner wall of the top shell 1, and the other end is connected to the inner wall of the bottom shell 2. The clamp 3 is inserted from the clamping port 11 and slides into the channel along the inclined slide 23. The top shell 1 has a window 12 above the channel for the push switch 4 to move. Guide plates 13 are provided on both sides of the window 12. The guide plates 13 can make the push switch 4 move more smoothly within the window 12 and ensure that the clamp 3 does not deviate during the pushing process. Please refer to Figure 3 , Figure 3This is a schematic diagram of the push-button switch 4 of this utility model. The push-button switch 4 is placed inside the window 12. The push-button switch 4 includes an L-shaped push clamp 41 and a protrusion 42. The L-shaped push clamp 41 includes a horizontal plate 411 and a vertical plate 412. The protrusion 42 is provided on the horizontal plate 411. The horizontal plate 411 has slots on both sides, which engage with the guide plate 13. The vertical plate 412 is placed in the channel and fits against the clamp 3 so as to push the clamp 3 forward. The end of the horizontal plate 411 near the clamping port 11 is connected to the inner wall of the top shell 1 through a return spring 5. The return spring 5 can ensure that the push-button switch 4 can automatically reset after completing one push operation, preparing for the next operation. A more preferred solution is to provide a U-shaped groove 4111 on the horizontal plate 411. A connector is provided in the U-shaped groove 4111. The horizontal plate 411 is connected to the return spring 5 through the connector. This design can make the connection between the horizontal plate 411 and the return spring 5 more firm and reliable. The protrusion 42 is connected to the drive component via a telescopic component. Specifically, one end of the telescopic component is connected to the drive end of the drive component, and the other end is screwed into the interior of the protrusion 42. The drive component is located on the top shell 1. In this embodiment, the drive component is a drive motor. The drive component drives the telescopic component to extend and retract, thereby driving the push switch 4 to move back and forth along the guide plate 13 within the window 12. This enables automated operation of the push clamp, freeing up the hands and improving work efficiency. This embodiment also provides another technical solution: the hemispherical surface of the protrusion 42 is provided with transverse anti-slip textures. When the drive component fails, the telescopic component and the drive component can be removed, and the push switch 4 can be manually pushed to move back and forth along the guide plate 13 within the window 12. The addition of transverse anti-slip textures can increase the friction when the operator manually pushes the push switch 4, preventing the operator's fingers from slipping on the surface of the protrusion 42 of the push switch 4, thus making manual operation more stable and effortless, and ensuring that the pushing operation of the clamp 3 can still be completed smoothly in special circumstances such as drive component failure.

[0027] In this embodiment, infrared ranging sensors are also provided on the upper and lower sides of the clamping opening 21, and a controller is provided on the side wall of the shell. The driving component and the infrared ranging sensors are electrically connected to the controller. The infrared ranging sensors can detect the PCB thickness in real time. The controller can adjust the working state of the driving component according to the change of PCB thickness to control the clamping force of the clamp 3. If the detected PCB thickness is higher than the threshold, the controller will issue a command, and the driving component will drive the telescopic component to further push the push switch 4, so that the clamp 3 is opened by the elastic V-clamp at a larger angle. If it is lower than the threshold, the driving component will drive the telescopic component to operate in the opposite direction, so that the clamp 3 is opened by the elastic V-clamp at a smaller angle. Through this dynamic adjustment mechanism, it is ensured that the clamp 3 always clamps PCBs of different thicknesses with the most appropriate force, ensuring the stability of the PCB during the processing and avoiding displacement or damage to the PCB due to improper clamping.

[0028] To prevent static electricity from being generated during operation of the push clamp and thus avoid damage to electronic components on the PCB board, this embodiment also applies an anti-static coating to the surfaces of the top shell 1, bottom shell 2, guide plate 13, elastic V-clamp 22, push switch 4, and reset spring 5. Since the inner wall of the bottom shell 2 will frequently come into contact with and rub against components such as the clamp 3 during long-term use, a wear-resistant coating is also applied to the inner wall of the bottom shell 2 to extend its service life and reduce wear. To prevent the clamp 3 from scratching the PCB board's surface plating while holding the PCB board, and to increase the friction between the clamp 3 and the PCB board, preventing the PCB board from sliding during processing, a silicone protective layer is also provided on the surface of the clamp 3. To make the push clamp more durable, this embodiment uses stainless steel to make the top shell 1 and bottom shell 2. Stainless steel has excellent corrosion resistance, high strength, and is not easily deformed. Using stainless steel for the top shell 1 and bottom shell 2 ensures that the push clamp can work stably under various complex environmental conditions, reducing equipment damage and malfunctions caused by material issues and extending the equipment's service life.

[0029] During operation, clamp 3 is inserted through clamping port 11 and slides into the channel along inclined slide 23. As multiple clamps 3 are inserted into the channel, the first clamp 3 inserted is continuously lifted along guide slope 24. At this time, the drive unit drives the telescopic component to push the push switch 4 forward until the vertical plate 412 contacts the first clamp 3 inserted. As the push switch 4 continues to move forward, the vertical plate 412 will push the first clamp 3 inserted to continue moving forward until the clamp 3 is opened by the elastic V-clamp 22. At the same time, the infrared ranging sensor detects the PCB board thickness in real time. The controller can adjust the working state of the drive unit according to the change of PCB board thickness to control the clamping force of the clamp 3. When a thicker PCB board is detected, the push switch 4 is automatically increased to generate a larger deformation of the elastic V-clamp 22 to increase the clamping force. Conversely, when encountering a thin PCB board, the pushing force is reduced to avoid over-clamping and deformation of the board.

[0030] When a PCB board is finished and a new PCB board needs to be replaced, the operator inserts the new clamp 3 into the clamping port 11. At this time, the drive motor reverses to retract the telescopic component, and the push switch 4 smoothly returns to its initial position along the guide plate 13 under the action of the reset spring 5, preparing for the next push of the new clamp 3. The newly inserted clamp 3 slides into the channel along the inclined slide 23, and the clamp 3 that was inserted first is lifted again along the guide slope 24. The pusher begins a new round of operation, and so on, efficiently and stably completing the clamping operation of different PCB boards, ensuring the smooth progress of the entire PCB board processing flow, and improving production efficiency and product quality.

[0031] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
