[0025] This embodiment provides a technical solution: a fixture for controlling deep processing and fixing PCB products, such as Figure 1-4 As shown, it includes: a processing table 1, a top block 2 and a quick covering component 3;

[0026] like Figure 1-4 As shown, a receiving groove 4 and operating openings 8 on both sides of the receiving groove 4 are provided at the center of the processing table 1. The receiving groove 4 is used to clamp the PCB board, and the operating opening 8 can facilitate the installation of a quick cover assembly 3 on the processing table 1; a top block 2 is installed in the receiving groove 4, and the top block 2 is used to support the PCB board; the quick cover assembly 3 includes a control pedal 301 and two covering structures located at the bottom of the processing table 1, and the control pedal 301 is used to control the opening and closing of the two covering structures, such as Figure 1 and Figure 3As shown, two covering structures are mirror-imaged on both sides of the top of the control pedal 301 and are arranged in the operating port 8. The covering structure includes a covering plate 302, a limiting plate 303, a pull rope 304 and a limiting spring 305. The covering plate 302 is located in the operating port 8. The top block 2 and the covering plate 302 can fix the PCB board. The limiting plate 303 is fixedly installed on one side of the inner wall of the operating port 8 and a through hole is opened at its center. The pull rope 304 is installed between the covering plate 302 and the control pedal 301 and is passed through the through hole. The limiting spring 305 is installed between the covering plate 302 and the limiting plate 303 and is sleeved on the outside of the pull rope 304. The limiting plate 303 is used to limit the pull rope 304 and the limiting spring 305. The limiting spring 305 can drive the covering plate 302 to reset. Figure 1 As shown, at this time, the two cover plates 302 are symmetrically arranged on the top of the accommodating groove 4, and the pull rope 304 is in a relaxed state. By stepping on the control pedal 301 with the foot, the control pedal 301 moves downward to pull the pull rope 304.

[0027] like Figure 1 As shown, at this time, the two covering plates 302 are symmetrically arranged on the top of the receiving groove 4 and completely cover the receiving groove 4. By stepping on the control pedal 301, the control pedal 301 moves downward to pull the two pull ropes 304. The two pull ropes 304 slide in the two limit plates 303. The two pull ropes 304 pull the two covering plates 302, and the two covering plates 302 move away from each other. The two covering plates 302 respectively squeeze the limit springs 305 connected thereto, and the limit springs 305 are pressed by the limit plates 303. 3 limit, the limit spring 305 generates opposite thrusts on the two cover plates 302, the receiving groove 4 is completely leaked, the PCB board is placed on the top block 2 in the receiving groove 4, the control pedal 301 is loosened, and after the two pull ropes 304 lose the tension, the two cover plates 302 lose the tension of the two pull ropes 304, the limit spring 305 pushes the two cover plates 302 to move closer to each other, and the PCB board is fixed between the top block 2, the two cover plates 302 and the receiving groove 4, so that the PCB board can be quickly fixed.

[0028] like Figure 3 As shown, a reset assembly 5 is installed at the bottom of the quick cover assembly 3, and the reset assembly 5 is used to reset the control pedal 301. The reset assembly 5 includes a vertical rod 501 inserted through the control pedal 301 and a reset spring 502 fixedly connected to the control pedal 301. The vertical rod 501 is inserted into the reset spring 502, and the vertical rod 501 can prevent the reset spring 502 from tilting. A horizontal plate 503 is fixedly installed at the bottom of the reset spring 502, and the reset spring 502 can drive the control pedal 301 to reset. The horizontal plate 503 is fixedly connected to the vertical rod 501, and the horizontal plate 503 is fixedly connected to the processing table 1.

[0029] When the control pedal 301 is stepped on, the control pedal 301 slides in the vertical rod 501, and the control pedal 301 presses the return spring 502 downward. The bottom of the return spring 502 is limited and fixed by the horizontal plate 503. The return spring 502 contracts to generate elastic force. The return spring 502 gives a thrust in the direction of the control pedal 301. When the control pedal 301 is loosened, the return spring 502 drives the control pedal 301 to rise, and the control pedal 301 can be reset.

[0030] like Figure 4 As shown, a lifting component 6 is installed under the processing table 1, and the lifting component 6 is used to control the lifting and lowering of the top block 2. The lifting component 6 includes a support rod 601 fixedly installed on the processing table 1 and a push rod 602 rotatably connected to the top block 2. A rotating pedal 603 is sleeved on the support rod 601, and the rotating pedal 603 is rotatably connected to the push rod 602. The rotating pedal 603 is supported by the support rod 601 and can rotate on the support rod 601 to drive the push rod 602 to rise and fall.

[0031] When the PCB needs to be turned over, the control pedal 301 is stepped on with one foot according to the above steps of stepping on the control pedal 301, so that the PCB can be completely exposed, and the rotating pedal 603 is stepped on with the other foot to move away from the end of the push rod 602, and the rotating pedal 603 rotates with the central axis of the support rod 601 as the rotation axis, and the end of the rotating pedal 603 away from the push rod 602 is lowered, and the end of the rotating pedal 603 close to the push rod 602 is raised, and the push rod 602 pushes the top block 2 upward, and the top block 2 moves up in the receiving slot 4, and the top block 2 can push the PCB out of the receiving slot 4, so that the PCB can be conveniently turned over by hand.

[0032] like Figure 1 As shown, a slide groove 7 is provided on the side wall of the operation opening 8, and the cover plate 302 is slidably connected to the slide groove 7. The slide groove 7 can limit the sliding cover plate 302 to prevent the cover plate 302 from tilting.

[0033] The working principle of the utility model is as follows: Figure 1 and Figure 3As shown, at this time, the two covering plates 302 are symmetrically arranged on the top of the accommodating groove 4, and the pull rope 304 is in a relaxed state, and the limit spring 305 is in a compressed state. When the PCB board needs to be grooved, the groove tool is stuck between the two covering plates 302. The two covering plates 302 are both made of transparent materials, and the PCB board can be seen. When the groove opening direction moves toward the left covering plate 302, the tool squeezes the left covering plate 302, and the right covering plate 302 is pushed by the limit spring 305 connected thereto, and the right covering plate 302 moves with the tool toward the left covering plate 302. When the groove opening direction moves toward the right covering plate 302, the tool squeezes the right covering plate 302, and the left covering plate 302 is pushed by the limit spring 305 connected thereto, and the left covering plate 302 moves with the tool toward the right covering plate 302. The top of the PCB board is always covered, which can reduce the damage to the PCB board rocker.
