An upper part of the connecting rod 5 is fixedly connected with a mounting plate 7. A connecting member 8 is provided on the mounting plate 7, and a pressing part 9 is fixedly connected to a lower part of the connecting member 8. A placing groove 10 is arranged in the middle of the workbench 2, and a second through hole 11 is opened at the bottom of the placing groove 10. An inclined panel 12 is arranged below the workbench 2, and a collecting box 13 is slidably connected to one side of the inclined panel 12. A pushing part 14 is arranged at one end of the workbench 2 away from the pressing part 9. A first cleaning assembly 15 is arranged below the workbench 2, and electric slide rails 16 are arranged on both sides of the workbench 2. A second cleaning assembly 17 is slidably connected to the electric slide rails 16.

[0027] Lay the edge of the circuit board on the edge of the placing groove 10. Start the pushing part 14 to drive the circuit board to approach the pressing part 9. Then start the lifting push rod 4 to drive the pressing part 9 to approach and press the upper surface of the circuit board. After the circuit board is fixed, use the first cleaning assembly 15 and the second cleaning assembly 17 to clean the upper surface and the lower surface of the circuit board respectively. The dust swept off falls on the inclined panel 12 and finally enters the collecting box 13 for collection and treatment.

[0028] The connecting rod 5 includes a first connecting part 51, and the first connecting part 51 is rotatably connected to the lifting push rod 4. A second connecting part 52 is arranged on an upper part of the first connecting part 51, and a sliding groove 53 is opened on the second connecting part 52.

The connecting rod 62 is slidably connected to the sliding groove 53.

[0029] Start the lifting push rod 4 to push the connecting rod 5 to move upward. At this time, the first connecting part 51 rotates, driving the second connecting part 52 to rotate around the connecting rod 62. During this process, due to the blocking and limiting effect of the connecting rod 62, the pressing part 9 on the upper part of the first connecting part 51 rotates along a counterclockwise trajectory of the positioning member 6, thus moving away from the surface of the workbench 2. After placing the circuit board on the workbench 2, the height of the output end of the lifting push rod 4 decreases until the pressing part 9 forms a 90° angle with the horizontal plane to press the upper surface of the circuit board on this side.

[0030] The pressing part 9 includes an L-shaped plate 91 and a spring 94. A lifting rod 92 is slidably connected to the L-shaped plate 91.

[0033] Start the motor 151, drive the first cleaning brush 155 to move along the guide rod 153 through the moving seat 154, and clean the lower surface of the circuit board.

[0034] The second cleaning assembly 17 includes a bracket 171. Both sides of the bracket 171 are slidably connected to the electric slide rail 16. A second cleaning brush 172 is arranged at the lower part of the bracket 171.

[0035] The bracket 171 drives the second cleaning brush 172 to move along the electric slide rail 16 to clean the upper surface of the circuit board.

[0036] A dust suction device 18 is further arranged at one end of the workbench 2 away from the pressing part 9. A telescopic hose 19 is arranged on the dust suction device 18.

[0038] The working principle of an integrated circuit board dust removal device for integrated circuit testing provided by the present utility model is as follows:

[0039] Place the edge of the circuit board on the edge of the placement groove 10. Start the pushing part 14 to drive the circuit board closer to the pressing part 9. Then start the lifting push rod 4 to drive the pressing part 9 to approach and press the upper surface of the circuit board. After the circuit board is fixed, use the first cleaning component 15 and the second cleaning component 17 to clean the upper surface and the lower surface of the circuit board respectively. The dust swept off falls on the inclined panel 12 and finally enters the collection box 13 for collection and treatment.

[0040] Compared with the related art, an integrated circuit board dust removal device for integrated circuit testing provided by the present utility model has the following beneficial effects:

[0041] The pushing part 14 pushes the circuit board to the lower part of the pressing part 9. Then start the lifting push rod 4 to drive the pressing part 9 to approach and press the upper surface of this side of the circuit board. Then start the first cleaning component 15 and the second cleaning component 17 to clean the upper surface and the lower surface of the circuit board respectively.
