The grinder 8 moves the grinding head 9, so that the grinding head 9 can grind a single side of the PCB circuit board, and the base 3 is supported and fixed on the bottom plate 1 by the support columns 2; and further includes:

[0026] The lifting platform 5 is connected with the base 3, and the two sides of the lifting platform 5 are respectively fixedly connected with the slide seats 10. The PCB circuit board is placed on the lifting platform 5. The lifting platform 5 is connected with the base 3, and the lifting platform 5 drives the PCB circuit board to slide up and down on the base 3. The lifting platform 5 is height-adjusted according to the thickness of the PCB circuit board, so that the PCB circuit board with uneven thickness can be fully polished, wherein the slide seats 10 provide a limit function for the two sides of the lifting platform 5; and

[0027] The fixing seat 14 is fixed on the top of the sliding seat 10. The fixing seat 14 is provided with a threaded hole 15. A threaded rod 16 is connected to the inner thread of the threaded hole 15. The threaded rod 16 moves by rotating on the fixing seat 14. The threaded rod 16 supports and fixes the PCB circuit board. The threaded rod 16 is connected to the threaded hole 15 by threads, and the fixing seat 14 can fix the threaded rod 16.

[0028] In some specific embodiments, the lifting platform 5 is fixedly connected to a vertical baffle 7 at the side end away from the fixed seat 14, and the lifting platform 5 is fixedly connected to a horizontal baffle 6 at the side end perpendicular to the vertical baffle 7. When the PCB circuit board is placed on the lifting platform 5, the two ends of the PCB circuit board that are perpendicular to each other are respectively abutted against the horizontal baffle 6 and the vertical baffle 7. The horizontal baffle 6 and the vertical baffle 7 ensure the stability of the PCB circuit board when it is polished on the lifting platform 5.

[0029] In some specific implementation schemes, two groups of slides 10 are provided, and a connecting plate 18 is provided between the two groups of slides 10. The left and right ends of the connecting plate 18 are respectively fixed to the slides 10, and the bottom end of the connecting plate 18 is fixedly connected to a guide rod 11, and the bottom end of the guide rod 11 is fixedly connected to a cylinder 19, and the bottom end of the cylinder 19 is fixedly connected to the bottom plate 1, and the cylinder 19 drives the guide rod 11 to move up and down, and the guide rod 11 drives the connecting plate 18 to move up and down, and the connecting plate 18 drives the slide 10 to move up and down, and the slide 10 drives the lifting platform 5 to move up and down, and the lifting platform 5 drives the PCB circuit board to move up and down, thereby realizing the height adjustment of the PCB circuit board, wherein the connecting plate 18 ensures that the two groups of slides 10 are supported by the guide rod 11 in a balanced manner.

[0030] In some specific implementation schemes, slide grooves 12 are respectively opened on both sides of the base 3, and the slide grooves 12 are slidably connected to the slide seat 10. A plurality of limit grooves 13 are opened on both sides of the base 3 in a direction parallel to the length of the lifting platform 5. The lifting platform 5 is fixedly connected with a plurality of limit columns 4 at both ends in a direction parallel to the length of the transverse baffle 6. The supporting and limiting effect provided by the base 3 is transmitted to the slide seat 10 through the slide groove 12, and then transmitted to the lifting platform 5 through the slide seat 10, thereby ensuring the stability of the lifting platform 5 when it moves up and down on the base 3, and avoiding the lifting platform 5 from overturning when carrying the PCB circuit board for grinding.

[0031] In some specific implementation schemes, the limiting column 4 is semi-cylindrical in shape, and the limiting column 4 is slidably connected to the limiting groove 13. The lifting platform 5 moves up and down with the limiting column 4, and the limiting column 4 slides along the limiting groove 13. The limiting support provided by the limiting groove 13 is transmitted to the lifting platform 5 through the limiting column 4, thereby further improving the stability of the lifting platform 5.

[0032] In some specific embodiments, the threaded rod 16 is fixedly connected to a supporting plate 17 at the side end near the vertical baffle 7. The supporting plate 17 is circular in shape and does not contact the base 3. When the threaded rod 16 supports and fixes the PCB circuit board, the supporting plate 17 contacts and supports the PCB circuit board. The supporting plate 17 has plasticity, which prevents the PCB circuit board from being damaged by the support.

[0033] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0034] The PCB circuit board is placed on the lifting platform 5, and the two ends of the PCB circuit board that are perpendicular to each other are respectively abutted against the horizontal baffle 6 and the vertical baffle 7. The threaded rod 16 moves by rotating on the fixing seat 14. The threaded rod 16 abuts and fixes the PCB circuit board. The threaded rod 16 is connected with the threaded hole 15 by threads, and the fixing seat 14 can fix the threaded rod 16. When the threaded rod 16 abuts and fixes the PCB circuit board, the abutting plate 17 contacts and abuts the PCB circuit board. The abutting plate 17 has plasticity, and the abutting plate 17 avoids the phenomenon that the PCB circuit board is damaged by abutment. The horizontal baffle 6 and the vertical baffle 7 ensure the stability of the PCB circuit board when it is polished on the lifting platform 5;

[0035] When the grinder 8 moves the grinding head 9 and the grinding head 9 grinds one side of the PCB circuit board, the cylinder 19 drives the guide rod 11 to move up and down, the guide rod 11 drives the connecting plate 18 to move up and down, the connecting plate 18 drives the slide 10 to move up and down, the slide 10 drives the lifting platform 5 to move up and down, the lifting platform 5 drives the PCB circuit board to move up and down, so that the lifting platform 5 can adjust the height of the PCB circuit board, thereby achieving that the PCB circuit board with uneven thickness can be fully polished, thereby ensuring the polishing effect of the PCB circuit board with uneven thickness.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
