[0002] Circuit boards are one of the important components of the electronics industry. Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, must use printed circuit boards for electrical interconnection between them. Therefore, circuit boards are widely used. During the manufacturing process of circuit boards, polishing is required.

[0003] When the circuit board is laid flat on the support for polishing, the fixing effect of the circuit board is poor, so that the circuit board is easy to move during the polishing process, and the polishing effect is poor. At the same time, a circuit board is generally placed on the mounting seat for polishing. After the polishing is completed, the product is removed and a new product is placed to continue polishing. During the entire process from removing the processed product to putting the new product in, the polishing mechanism is in an idle state, which seriously affects the processing efficiency.

DETAILED DESCRIPTION

[0016] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0017] A circuit board polishing mechanism, comprising a support seat 1, wherein a circular hole 2 is arranged in the middle of the support seat 1, wherein a plurality of groups of rectangular grooves 3 for accommodating circuit boards are circumferentially arranged on the top surface of the support seat 1 outside the circular hole 2, and an air suction cavity 4 connected to a vacuum pump through a pipeline is arranged in the support seat 1 below the rectangular groove 3, and the air suction cavity 4 is connected to the rectangular groove 3 through a plurality of air suction holes 5;

[0018] A circular seat 6 driven by a motor I7 is arranged in the circular hole 2, wherein a hydraulic rod 8 is arranged above the circular seat 6, and the output shaft of the hydraulic rod 8 is connected to a mounting frame 10 located directly above one of the groups of rectangular grooves 3 through a square rod 9, and a box body 11 with an opening facing downward is arranged at the bottom of the mounting frame 10, wherein a polishing roller 12 driven by a motor II13 is arranged in the opening of the box body 11, and the bottom end of the polishing roller 12 extends to the outside of the bottom opening of the box body 11, and an exhaust fan 14 connected to the interior of the box body 11 through a pipeline is also arranged at the top of the box body 11, wherein a dust removal bag 15 is arranged on the outlet end of the exhaust fan 14.

[0019] like Figure 1 As shown, the circular seat 6 is adapted to the circular hole 2 in size, wherein a circle of arc grooves is correspondingly arranged on the side wall of the circular hole 2 and the outer arc wall of the circular seat 6, and a plurality of balls 16 are arranged in the two groups of arc grooves. The circular seat 6 is movably fixed in the circular hole 2 by the way that the balls 16 hang on the arc grooves, thereby reducing the squeezing force caused by the circular seat 6 and other components on the motor 17. At the same time, when the motor 17 drives the circular seat 6 to rotate, it can drive the arc groove to slide on the balls 16 to reduce the resistance it encounters during rotation.

[0020] like Figure 1 As shown, a support 17 is provided at the top of the circular seat 6, wherein a receiving groove for receiving the hydraulic rod 8 is provided on the support 17, and a fixed channel 18 for the square rod 9 to pass through is provided at the top of the receiving groove, and the size of the square rod 9 is adapted to the size of the fixed channel 18. The fixed channel 18 is pressed against the side wall of the square rod 9 to prevent the mounting frame 10 and other components from driving the square rod 9 to rotate and twisting the output shaft and other components of the hydraulic rod 8 when the hydraulic rod 8 drives the mounting frame 10 to move up and down through the square rod 9.

[0021] like Figure 1 As shown, the length of the polishing roller 12 is greater than the length of the rectangular groove 3, and one group of rectangular grooves 3 is located directly below the two ends of the polishing roller 12. Then, when the mounting frame 10 and the box body 11 drive the polishing roller 12 to rotate, the working polishing roller 12 can cover the entire top surface of the circuit board.

[0022] like Figure 1 , 2 As shown, a circle of slide grooves 19 are arranged around the top surface of the support seat 1 outside the rectangular groove 3, wherein a slide rod 20 with its bottom end located in the slide groove 19 is arranged at the bottom of one end of the box body 11.

[0023] When the mounting frame 10 and the box body 11 drive the polishing roller 12 to rotate, the box body 11 drives the slide bar 20 to slide in the slide groove 19, and the slide bar 20 supports and fixes the suspended ends of the box body 11 and the mounting frame 10.

[0024] The method of using the present invention is as follows: by placing the circuit board in the rectangular groove 3, the top of the circuit board extends to the outside of the top of the rectangular groove 3, and vacuuming is performed by a vacuum pump, an air suction cavity 4 and an air suction hole 5, so that the circuit board is adsorbed and fixed in the rectangular groove 3 to prevent the circuit board from being displaced during subsequent processing;

[0025] Then the motor II13 drives the polishing roller 12 to work, and at this time the hydraulic rod 8 drives the square rod 9 to drive the mounting frame 10, the box body 11 and the polishing roller 12 to move downward, so that the polishing roller 12 in the working process contacts with the top surface of one group of circuit boards. At this time, the working polishing roller 12 can polish and grind the top surface of the circuit board, and in this process, the exhaust fan 14 works to draw the debris or dust obtained by grinding into the dust bag 15 through the opening of the box body 11 for filtration, wherein the gas is discharged and the impurities are filtered and collected in the dust bag 15, so as to achieve the dust removal and filtration effect on the air to improve the environment;

[0026] In the above process, the motor I7 drives the circular seat 6 to drive the hydraulic rod 8, square rod 9, mounting frame 10, box body 11 and polishing roller 12 to perform 360-degree reciprocating rotation, so that the polishing roller 12 in the working process can grind and polish the circuit boards in several rectangular grooves 3 on the support seat 1. At the same time, after the products in one group of rectangular grooves 3 are polished, and the polishing roller 12 moves to the top of the next group of rectangular grooves 3, people can calmly take out and replace the products in the rectangular grooves 3 after polishing, without stopping the polishing roller 12 and other components to replace the circuit board, thereby ensuring the continuity of the circuit board grinding to improve the grinding efficiency. In this embodiment, the reason why the circular seat 6 and other components perform 360-degree reciprocating rotation is to prevent the pipes connected to the mechanical equipment from being pulled apart by moving in only one direction.

[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
