Detailed Implementation

[0024] 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.

[0025] Example 1: As Figures 1-6The technical solution shown is a grinding machine for printed circuit board production. To solve the problem of low grinding efficiency, it discloses: a housing 1 and a support 2 installed on the inner wall of the housing 1, with a platform 3 installed on the upper end of the support 2, and a circuit board body 4 installed on the upper end of the platform 3; a guide rod 11 is installed through the inner wall of the housing 1, with an auxiliary plate 12 installed on the inner end of the guide rod 11, and a four-corner grinding mechanism is provided on the outer side of the auxiliary plate 12; a dual-head servo motor 5 is fixedly installed on the lower end of the support 2, and a first bevel gear 6 is fixedly installed on the upper output end of the dual-head servo motor 5; a second bevel gear 7 is meshed on the upper end of the first bevel gear 6; a bidirectional threaded rod 8 is provided inside the second bevel gear 7, and the surface of the bidirectional threaded rod 8 is threaded... The plate 9 is installed with a clamping plate, and a limit rod 10 is installed through the inside of the clamping plate 9. The two ends of the limit rod 10 are fixedly installed at the lower end of the storage platform 3. The clamping plate 9 and the circuit board body 4 form a pressing structure. The four corner rounding mechanism is provided with a grinding plate 13, and a mounting block 14 is fixedly installed on the outside of the grinding plate 13. The lower end of the mounting block 14 is nested inside the auxiliary plate 12. The mounting block 14 is T-shaped. The surface of the grinding plate 13 is provided with grinding paper. The surface of the guide rod 11 is fitted with a buffer spring 15. The inner and outer sides of the buffer spring 15 are located between the housing 1 and the auxiliary plate 12. A damper 16 is installed through the inside of the housing 1, and the inner side of the damper 16 is installed on the outer side of the auxiliary plate 12.

[0026] In use, the lower end of the circuit board body 4 is placed on the surface of the storage platform 3 on the bracket 2. At this time, by starting the dual-head servo motor 5, the upper first bevel gear 6 can be driven to rotate. When the first bevel gear 6 rotates, it can drive the second bevel gear 7 that meshes with it to rotate. When the second bevel gear 7 rotates, it drives the bidirectional threaded rod 8 to rotate. When the bidirectional threaded rod 8 rotates, it can drive the clamping plate 9 that is threaded to its surface. Under the limitation of the limiting rod 10, the clamping plate 9 clamps the circuit board body 4. After the circuit board is clamped, the motor is started to drive the circuit board. The storage platform 3 and the upper circuit board body 4 rotate. The rotating circuit board body 4 rotates and contacts the outer grinding plate 13. Since the grinding plate 13 is embedded in the auxiliary plate 12 through the mounting block 14, as the circuit board body 4 presses against the guide rod 11 on the outside of the auxiliary plate 12, it slides along the inside of the box 1. The buffer spring 15 and the damper 16 provide auxiliary buffering and shock absorption. At the same time, as the circuit board rotates and contacts the grinding plate 13, it can automatically round the four corners on the outside of the circuit board body 4. The four corners are rounded at the same time, which is simple and convenient to operate and has high processing efficiency.

[0028] When in use, as the dual-head servo motor 5 is started, the lower end of the dual-head servo motor 5 drives the wind collector wheel 17. When the wind collector wheel 17 rotates, it can draw in airflow from top to bottom, so that the wind carries dust into the collection box 18. The dust inside the collection box 18 is collected, and the wind blows out from the openings on the left and right sides. The collection box 18 is threadedly connected to the upper box 1, which can be easily removed to achieve the effect of reducing dust.
