[0031] In the related art, in the prior art, the production of circuit boards requires the use of edge grinding machines to process and grind the side edges of the circuit boards to avoid excessive burrs or unevenness on the edge parts, which affects the final quality of the product.

[0032] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides an edge grinding device for circuit board production. When it is needed, it is only necessary to start the electric telescopic rod 21 to drive the grinder 22 to grind the circuit board 19. After the circuit board 19 is polished, the motor 12 is used to move the polished circuit board 19 away from the grinder 22, and the next group of circuit boards 19 is moved to the position of the grinder 22. Then the operator can replace the polished circuit board 19. The device can continue to polish the next group of circuit boards 19 while replacing the circuit board 19, thereby increasing the working efficiency.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 3 The embodiment of the present application provides an edge grinding device for circuit board production, including a fixing component 1; the fixing component 1 includes: a bracket 11, an inner side of which is provided with a motor 12; a movable plate 121 is provided on the output shaft of the motor 12; a frame 13 is symmetrically provided at the bottom of the movable plate 121; a motor 2 14 is provided on the inner side of the frame 13; a top plate 141 is provided on the output shaft of the motor 2 14; a connecting rod 15 is provided at the bottom of the movable plate 121; a connecting plate 16 is provided at the bottom of the connecting rod 15; a screw 17 is provided at the bottom of the connecting plate 16 and is threadedly connected to the connecting plate 16; a bottom plate 171 is rotatably provided at the top of the screw 17; rubber pads 18 are respectively provided at the bottom of the top plate 141 and the top of the bottom plate 171; a circuit board 19 is provided at the top of the bottom plate 171;

[0035] The bracket 11 is also provided with a grinding assembly 2 , which includes: an electric telescopic rod 21 provided on the inner side of the bracket 11 ; and a grinder 22 provided on the electric telescopic rod 21 .

[0036] First, the electric telescopic rod 21 is started by an external power supply to drive the grinder 22 to move, so that the grinder 22 contacts the circuit board 19, and then the grinder 22 is started to grind one side of the circuit board 19. The grinder 22 is a mechanism that grinds the circuit board 19 by driving the grinding disc by a motor. After the grinding of one side of the circuit board 19 is completed, the electric telescopic rod 21 is started again to drive the grinder 22 away from the circuit board 19, and then the motor 2 14 is started by an external power supply to drive the top plate 141 to rotate. Since the bottom plate 171 is rotatably connected to the screw 17, and rubber pads 18 are respectively arranged on the top of the bottom plate 171 and the bottom of the top plate 141 to squeeze the circuit board 19, the circuit board 19 can be driven to rotate when the motor 2 14 rotates, and the side to be polished is brought close to the grinder 22, and then the electric telescopic rod 21 is started again. The rod 21 drives the grinder 22 to contact the circuit board 19. After the four sides of the circuit board 19 are polished in sequence, the motor 12 is started by an external power supply to drive the movable plate 121 to rotate, so that the polished circuit board 19 is moved away from the grinder 22, and then the next group of circuit boards 19 to be polished are moved to the position of the grinder 22. Then the operator releases the fixation of the circuit board 19 by rotating the screw 17 threadedly connected to the connecting plate 16, removes the circuit board 19, and then places the next group of circuit boards 19 on the top of the bottom plate 171, and then rotates the screw 17 to squeeze and fix the circuit board 19, so that the next group of circuit boards 19 can continue to be polished while the circuit board 19 is replaced, making the replacement more convenient, reducing the difficulty of operating the device and increasing the working efficiency.

[0037] In some embodiments, an auxiliary component 3 is disposed on the connecting plate 16 , and the auxiliary component 3 includes a brush 31 disposed on the top of the connecting plate 16 .

[0038] A brush 31 is provided on the top of the connecting plate 16 so that the surface of the polished circuit board 19 can be cleaned to avoid dust or debris from being adhered to the surface, making the surface tidier and more convenient for operators to store.

[0039] In some embodiments, the brush 31 is connected to the connecting plate 16 by bolts.

[0040] The brush 31 and the connecting plate 16 are connected by bolts, which facilitates the subsequent removal of the brush 31 , so that the damaged and deformed brush 31 can be removed and replaced, so as not to affect the cleaning of the circuit board 19 .

[0041] In some embodiments, the auxiliary component 3 further includes a circular groove 34 opened on the top of the connecting plate 16 .

[0042] A circular groove 34 is provided on the top of the connecting plate 16 , so that when the brush 31 is subsequently installed, it is inserted into the inner side of the circular groove 34 , which can facilitate subsequent fixing with bolts and increase the structural stability of the brush 31 .

[0043] In some embodiments, the auxiliary component 3 also includes: a second screw 32 is arranged at the bottom of the connecting plate 16, threadedly connected to the connecting plate 16, and inserted into the connecting rod 15; a docking groove 33 is opened at the top of the connecting plate 16.

[0044] A second screw 32 is provided at the bottom of the connecting plate 16. Since the second screw 32 is threadedly connected to the connecting plate 16, during subsequent disassembly, the connecting plate 16 can be disassembled by simply screwing the second screw 32 to remove it from the inside of the connecting rod 15, and the parts can be maintained or replaced. During subsequent installation, the connecting rod 15 is inserted into the inner side of the docking groove 33, and then the second screw 32 is screwed to insert it into the connecting rod 15 to complete the fixing of the connecting rod 15. In this way, the connecting plate 16 is installed.

[0045] In some embodiments, the docking groove 33 is rectangular.

[0046] The docking groove 33 is set to a rectangle, so that when the connecting plate 16 is subsequently installed, the position of the bottom plate 171 set on the connecting plate 16 can be easily determined so that it is in a vertical line with the top plate 141, and there is no need to adjust the position of the bottom plate 171 back and forth, making the installation more convenient.

[0047] In some embodiments, the auxiliary component 3 further includes a limiting groove 35 opened on the top of the connecting plate 16 .

[0048] A limiting groove 35 is provided on the top of the connecting plate 16 , so that when the bottom plate 171 rotates, the bottom plate 171 can be limited, thereby increasing the structural strength of the bottom plate 171 .

[0049] In some embodiments, the auxiliary component 3 further includes a collection box 36 disposed on the inner side of the bracket 11 .

[0050] A collection box 36 is provided at the inner bottom of the bracket 11, so that the debris or dust generated by grinding can be collected to prevent the dust from being scattered everywhere, making it inconvenient for subsequent operators to clean up, thereby increasing the operating efficiency.
