DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0017] A circuit board edge grinding device comprises a machine platform 1, a base 2 driven by a motor 13 is arranged on the top of the machine platform 1, a plurality of groups of strip grooves 4 are arranged vertically and crosswise on the top of the base 2, a suction pipe 5 connected with the strip grooves 4 is arranged at the bottom of the base 2, and the suction pipe 5 is connected with a vacuum pump through a hose;

[0018] An L-shaped frame I6 is provided on the top of the machine 1, wherein a sleeve 7 driven by an electric push rod I8 is provided on the L-shaped frame I6, and a vertical rod 9 is fixed in the sleeve 7 through a bearing, and a pressing block 10 located above the middle of the top of the base 2 is provided at the bottom end of the vertical rod 9;

[0019] A grinding roller 11 driven by a motor II12 is vertically arranged on one side of the base 2, wherein the motor II12 is arranged on a mounting seat 13, and a slide groove 14 with an isosceles trapezoidal cross-section is arranged on the top of the mounting seat 13, and the front and rear ends of the slide groove 14 are connected with the front and rear sides of the mounting seat 13, and a slide rail 15 adapted thereto is arranged in the slide groove 14, wherein the slide rail 15 is fixed to the L-shaped frame II27 through a connecting rod 16, and a screw rod 17 parallel to the slide rail 15 is also screwed on the mounting seat 13, and a screw hole screwed to the screw rod 17 is arranged on the mounting seat 13, and the screw rod 17 is driven by the motor III18, wherein a mounting frame 19 for fixing the motor III18 is arranged on the L-shaped frame II27.

[0020] like Figure 1 As shown, a sliding channel 20 is provided on one side wall of the machine 1, wherein a square rod 21 inserted into the sliding channel 20 is provided on the L-shaped frame II27, and an electric push rod II22 connected to the bottom end of the L-shaped frame II27 is also provided on the machine 1.

[0021] In this embodiment, a circle of arc-shaped grooves is arranged around the top of the base 2 outside the strip-shaped grooves 4, wherein a rubber sealing pad 23 is arranged in the arc-shaped grooves.

[0022] like Figure 1 As shown, a cylinder 24 is suspended at the bottom of the base 2, wherein a plurality of groups of receiving grooves with major arc cross-sections are evenly arranged on the bottom end surface of the cylinder 24, and a ball 25 is arranged in the receiving groove with one end extending to the outside thereof to abut against the top surface of the machine table 1.

[0023] The suspended base 2 is supported by the ball bearings 25 and the cylinder 24 . When the base 2 rotates, the cylinder 24 drives the ball bearings 25 to rotate on the top of the machine 1 and in the receiving groove, so as to reduce the resistance encountered by the cylinder 24 during rotation.

[0024] like Figure 1 As shown, a receiving groove 26 extending to the outside of the base 2 is arranged at the bottom edge of the base 2. The receiving groove 26 is used to collect the large pieces of debris obtained by grinding.

[0025] The working principle of the present invention is as follows: when in use, the circuit board is placed above the base 2, and its edges extend to the outside of the base 2, then the electric push rod I8 drives the sleeve 7 to drive the vertical rod 9 and the pressing block 10 to move downward, thereby squeezing the top of the circuit board to squeeze and fix it on the base 2, and at the same time, the vacuum pump works to absorb and fix the circuit board on the base 2 by vacuuming the suction pipe 5 and the strip groove 4, so that the circuit board is movably fixed on the base 2 in the above manner;

[0026] Then the electric push rod II22 drives the L-shaped frame II27 to move to the left, wherein the L-shaped frame II27 drives the square rod 21 to slide in the sliding channel 20, and the L-shaped frame II27 drives the grinding roller 11 to move to the left through the connecting rod 16, the slide rail 15, the mounting seat 13 and the motor II12, so that the grinding roller 11 is against the right end face of the circuit board. At this time, the motor II12 drives the grinding roller 11 to rotate to grind the right end face of the circuit board, wherein the motor III18 drives the screw rod 17 to rotate in the screw hole, while driving the mounting seat 13, the motor II12 and the grinding roller 11 to move back and forth, so that the grinding roller 11 can cover the entire side wall of the right end of the circuit board, and when the mounting seat 13 is moving, it will drive the slide groove 14 to slide on the slide rail 15 to prevent it from falling;

[0027] When the right side wall of the circuit board is polished and the position of the polishing roller 11 will not affect the rotation of the circuit board above the base 2, the motor I3 drives the base 2 to drive the circuit board above it to rotate, and the rotating circuit board drives the vertical rod 9 to rotate in the bearing through the pressure block 10, which prevents the pressure block 10 from affecting the rotation of the circuit board. At the same time, the pressure block 10 can also lock and fix the circuit board. When the polished end face of the circuit board is displaced to the right side, it can continue to be polished in the above manner. When in use, the base 2 performs a 360-degree reciprocating rotation to prevent it from rotating indefinitely in only one direction and pulling off the pipe connected to the base 2.

[0028] 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.
