[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] Please see Figure 1 In this embodiment, a grinding device for circuit board processing is used to grind both sides of the circuit board simultaneously, thereby increasing the grinding efficiency of the circuit board.

[0028] Specifically, it includes a base plate 1, at least two support columns 2, a placement plate 3, two grinding components 4, an adjustment component 5, and a clamping component 6; the placement plate 3 is mounted on the upper surface of the base plate 1 by at least two support columns 2, and two square openings are provided inside the placement plate 3; the two grinding components 4 are mounted on the base plate 1 by the adjustment component 5, and the adjustment component 5 is used to adjust the distance between the two grinding components 4.

[0029] The clamping component 6 is disposed on the placement plate 3 and is located between the two grinding components 4 for fixing the circuit board between the two grinding components 4.

[0030] In actual use, multiple circuit boards are fixed by clamping component 6 so that the two sides of the circuit board face the two polishing components 4 respectively. The distance between the two polishing components 4 is adjusted by adjusting component 5 so that the two polishing components 4 fit into the two sides of the circuit board respectively, thereby polishing the two sides of the circuit board.

[0031] Please see Figure 2 To facilitate the polishing of both sides of the circuit board, the two polishing components 4 in this embodiment are slidably connected inside the two square openings. One of the polishing components 4 includes a connecting plate 401 that is driven to the adjusting component 5. Columns 402 are installed on both the front and rear sides of the connecting plate 401. Two transmission rollers 403 are rotatably connected between opposite sides of the two columns 402. The two transmission rollers 403 are arranged vertically at intervals. The same sanding belt 404 is driven to the outside of the two transmission rollers 403. A drive motor 405 with its output end connected to one of the transmission rollers 403 is installed on one of the columns 402. The same horizontal plate 406 is fitted to the top of the two columns 402. The two sanding belts 404 are arranged symmetrically from left to right.

[0032] In actual use, the distance between the two grinding components 4 is adjusted by adjusting component 5, so that the sanding belts 404 on the two grinding components 4 are in contact with the two sides of the circuit board respectively. By turning on the drive motor 405 on the adjusting component 5, the output end of the drive motor 405 rotates and drives the upper transmission roller 403 to rotate. Through the transmission of the sanding belt 404, the other transmission roller 403 is simultaneously in a state of rotation. That is, the sanding belt 404 grinds the side of the circuit board during the rotation process.

[0033] In detail, in order to facilitate the adjustment of the spacing between the two sanding belts 404, the adjustment component 5 in this embodiment includes a slide rail 501 installed on the base plate 1. The two slide rails 501 are symmetrically arranged on the front and rear sides of the upper surface of the base plate 1, and the columns 402 on the front and rear sides are respectively slidably connected to the outer sides of the two slide rails 501.

[0034] Two bearing seats 503 are arranged at left and right intervals on the upper surface of the base plate 1. A lead screw 504 is rotatably connected between the opposite sides of the two bearing seats 503. A rotary motor 505 with its output end connected to the lead screw 504 is installed on the base plate 1. Connecting seats 502 are installed on the upper surfaces of the connecting plates 401 on both the left and right sides. Both connecting seats 502 are threadedly connected to the lead screw 504.

[0035] In practical use, the rotation of the output end of the rotary motor 505 drives the lead screw 504 connected to it to rotate. The lead screw 504 is threadedly connected to the connecting seat 502. When the lead screw 504 rotates, it drives the connecting seat 502 and the two connecting plates 401 to move in opposite directions. At the same time, it drives the left and right connected columns 402 and the sanding belts 404 on the left and right sides to move in opposite directions, thereby adjusting the distance between the two sanding belts 404, so that the two sanding belts 404 are respectively attached to the two sides of the circuit board.

[0036] It should be noted that the outer surface of the lead screw 504 has two threaded grooves with opposite thread directions. The two connecting seats 502 are symmetrically arranged on the outer side of the lead screw 504. The interior of the two connecting seats 502 is provided with threaded through holes that are adapted to the two threaded grooves.

[0037] Please see Figure 3 In order to facilitate fixing multiple circuit boards between two grinding components 4, the clamping component 6 in this embodiment includes a fixing seat 601 installed at the center of the upper surface of the placement plate 3. A screw 602 is threadedly connected to the front side of the inner wall of the fixing seat 601, and a fixing plate 603 is threadedly connected to the rear end of the screw 602. The fixing plate 603 is located inside the fixing seat 601.

[0038] In practical use, multiple circuit boards are placed inside the fixing base 601. The screw 602 is rotated to push the fixing plate 603 toward the circuit board, so that the fixing plate 603 is in contact with the front side of the circuit board, thereby fixing the circuit board inside the fixing base 601 and between the two sanding belts 404.

[0039] In actual installation, the side cross-section of the fixing base 601 in this embodiment is U-shaped, and the fixing plate 603 is attached to the inner bottom wall of the fixing base 601.

[0040] Furthermore, in order to ensure the stability of the fixing plate 603 during movement, two guide rods 604 are installed on the front side of the fixing plate 603 in this embodiment, and both guide rods 604 are disposed through the front side of the inner wall of the fixing base 601.

[0041] In actual use, when the fixing plate 603 moves, it can drive the guide rod 604 to move back and forth on the inner wall of the fixing base 601, thereby limiting the movement of the fixing plate 603 and ensuring the stability of the circuit board when it is fixed.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
