[0033] The rotation module 4 includes a square plate 45, which is fixedly connected to the lower side of the support frame 3. The central axis of one end of the worm 44 passes through and is movably connected to the square plate 45. The end of the central axis of one end of the worm 44 is fixedly connected to the motor 2 46. The motor 2 46 is fixedly connected to the square plate 45. The worm 44 engages with the worm gear 47. The central axis of the worm gear 47 passes through and is movably connected to the support frame 3. The end of the central axis of the worm gear 47 is fixedly connected to the rotating shaft 43. The upper side of the rotating shaft 43 is fixedly connected to the template 42. The four upper corners of the template 42 are respectively fixedly connected to the corresponding positioning pin shafts 41.

[0034] The pressing module 1 includes a cylinder 11 , a shell of the cylinder 11 is fixedly connected to a U-shaped plate 12 , and a telescopic rod of the cylinder 11 passes through the U-shaped plate 12 .

[0035] The end of the telescopic rod of the cylinder 11 is movably connected to the center of the pressing plate 13 .

[0036] The U-shaped plate 12 is fixedly connected to the support frame 3 .

[0037] The template 42 has the same dimensions as the standard circuit board 6 .

[0038] The position of the positioning pin 41 is the same as the position of the circular hole for fixing and installing on the circuit board 6 .

[0039] The diameter of the milling cutter 22 is the same as the diameter of the cylinder 21 .

[0040] Working principle: First, install the milling cutter 22 and the milling cutter fixture 23, and the milling cutter 22 is movably connected to the cylinder 21. Then, place the circuit board 6 to be polished on the template 42, and insert the positioning pins 41 into the circular holes for fixed installation on the circuit board 6, which can fix the circuit board 6 to a certain extent. Then, start the cylinder 11, and the telescopic rod of the cylinder 11 extends to drive the pressing plate 13 to move downward, so that the pressing plate 13 presses against the upper side of the circuit board 6. At this time, the cylinder 11 is closed;

Since the template 42 is the same size as the standard circuit board 6 and the diameter of the milling cutter 22 is the same as the diameter of the cylinder 21, the burrs on the edge of the circuit board 6 are cut off by the milling cutter 22. After the circuit board 6 rotates one circle, the grinding operation of the circuit board is completed.

[0043] Beneficial effect: The circuit board 6 to be polished is placed on the template 42, and the pressing module 1 is used to make the pressing plate 13 press against the upper side of the circuit board 6. The rotating module 4 is used to make the template 42 drive the circuit board 6, the pressing plate 13, etc. to rotate. At the same time, when the template 42 drives the circuit board 6 to rotate, the spring 53 is always in a stretched state. When the template 42 and the circuit board 6 rotate synchronously, the cylinder 21 always rotates in contact with the outer side of the template 42. The burrs on the edge of the circuit board 6 are polished by the polishing module 2, and the polishing operation of the circuit board can be completed.
