A T-shaped groove 10 adapted to the T-shaped plate 9 is provided at the inner bottom of the inclined groove 5, and the T-shaped groove 10 is communicated with the control groove 7. A slider 11 is slidably connected to the bottom of the T-shaped plate 9, and a counterweight plate 13 is rotatably connected to the bottom of the slider 11 through a rotating rod 12. A long groove is provided on the side of the counterweight plate 13 away from the T-shaped plate 9, and the long groove runs through the counterweight plate 13. A cross plate 14 is fixedly connected to the top of the hydraulic cylinder 8, and a side of the cross plate 14 away from the hydraulic cylinder 8 is slidably connected to the T-shaped plate 9;

[0036] The air pump 18 has an air inlet end that penetrates to the outside of the workbench 1 .

[0037] A track groove 15 is provided at the bottom of the T-shaped plate 9 , and a roller 16 is installed inside the track groove 15 . A support block 17 is rotatably connected to the bottom of the roller 16 . One end of the support block 17 away from the roller 16 extends to the outside of the track groove 15 and is fixedly connected to the cross plate 14 .

[0038] Elastic sheets 22 are fixedly connected to one end of the top of both sides of the inner wall of the air vent 21, a lifting plate 23 is slidably connected between the two sides of the inner wall of the air vent 21, a longitudinal column 24 is fixedly connected to the top of the lifting plate 23, one end of the top of the longitudinal column 24 passes through the elastic sheet 22 and extends to the outside of the air vent 21, a cross plate 25 is fixedly connected to one end of the longitudinal column 24 away from the lifting plate 23, and the bottom of the lifting plate 23 is fixedly connected to the inner wall of the air vent 21 through an elastic rod 26.

[0039] A blowing port 27 is provided on one side of the smooth ball 20 close to the T-slot 10, and the blowing port 27 is connected to the air vent 21. An elastic arc rod 28 is fixedly connected to one side of the longitudinal column 24 close to the blowing port 27. An end of the elastic arc rod 28 away from the longitudinal column 24 is fixedly connected to a slide plate 30 via a traction rope 29, and the slide plate 30 is slidably connected to the smooth ball 20.

[0040] When in use, the mobile phone motherboard to be polished is placed on the inclined groove 5 on the workbench 1, and the mobile phone motherboard slides into the inclined groove 5 from the end away from the bracket 2, and slides along the inclined groove 5. The inclined groove 5 with a gradually decreasing width clamps the mobile phone motherboard. Since the inclined grooves 5 are axially symmetrically distributed on the workbench 1, the mobile phone motherboard is located on the central axis of the workbench 1 when it is stuck and stops moving. The hydraulic cylinder 8 pushes the T-plate 9 to rise, and the T-plate pushes the mobile phone motherboard inside the inclined groove 5 to rise until the top of the mobile phone motherboard is pressed against the polishing wheel 4. The first motor 3 drives the polishing wheel 4 to rotate to polish the mobile phone motherboard. The position of the mobile phone motherboard can be adjusted to ensure that the mobile phone motherboard is polished in the middle position of the workbench 1, and the position deviation of the mobile phone motherboard during the transportation process is avoided, which leads to the deviation of the polishing position.

[0041] During the process of the T-shaped plate 9 being raised, the T-shaped plate 9 is raised to the outside of the T-shaped slot 10, and the end of the counterweight plate 13 close to the bracket 2 is no longer blocked by the T-shaped slot 10. Since the end of the counterweight plate 13 with a larger width is heavier, the end of the counterweight plate 13 close to the bracket 2 is deflected and tilted downward along the rotating rod 12, and the counterweight plate 13 drives the slider 11 to move along the lower surface of the T-shaped plate 9 toward the bracket 2. After the counterweight plate 13 moves to the end of the T-shaped plate 9 close to the bracket 2, the T-shaped plate 9 is pulled to move due to inertia, and the T-shaped plate 9 moves in the direction of the bracket 2. The mobile phone motherboard is polished by the polishing wheel 4 during the movement of the T-shaped plate 9, and the mobile phone motherboard can be driven by gravity to be transported in the horizontal direction for polishing, without the need for additional conveying equipment, and can ensure that the mobile phone motherboard is polished in the horizontal direction, which is convenient for controlling the speed and observing the polishing process;

[0042] After the mobile phone motherboard is polished, the hydraulic cylinder 8 drives the T-shaped plate 9 to descend, and the counterweight plate 13 is manually pushed to move to the bottom of the T-shaped plate 9, and the T-shaped plate 9 and the counterweight plate 13 are driven to the inside of the T-shaped slot 10;

[0043] When the mobile phone mainboard slides in the inclined groove 5, the mobile phone mainboard contacts the smooth ball 20, and the longitudinal column 24 on the top of the smooth ball 20 below the mobile phone mainboard is squeezed downward. The longitudinal column 24 pushes the lifting plate 23 to descend and squeezes and bends the elastic rod 26. The cross plate 25 descends with the longitudinal column 24, and the elastic sheet 22 is pushed downward and bent by the cross plate 25. The top of the air vent 21 is no longer completely blocked by the elastic sheet 22. The air pumped into the control groove 7 by the air pump 18 is partially blown upward from the air vent 21. The air blown upward from the bottom of the mobile phone mainboard can reduce the force of the mobile phone mainboard squeezing the inner wall of the inclined groove 5, thereby reducing the friction between the mobile phone mainboard and the equipment during the transportation process.

[0044] During the descent of the longitudinal column 24 below the mobile phone mainboard, the elastic arc rod 28 descends along with the longitudinal column 24, and the slide plate 30 blocks the air outlet 27 after descending a short distance. The air blown out by the smooth ball 20 at the bottom of the mobile phone mainboard is completely ejected upward from the air vent 21 to blow away the dust at the bottom of the mobile phone mainboard. The top of the air vent 21 on the smooth ball 20 that is not squeezed by the mobile phone mainboard is blocked by the elastic sheet 22, and the air is blown toward the mobile phone mainboard from the air outlet 27 on the side of the smooth ball 20. All-round blowing can be performed from different positions of the mobile phone mainboard to clean and collect dust on the surface, thereby improving the thoroughness of surface cleaning of the mobile phone mainboard.

[0045] Example 2

[0046] See also Figure 1-Figure 8The present invention provides a technical solution: on the basis of Example 1, a filter frame 31 is fixedly connected to one side of the workbench 1, a filter screen 32 is installed on the side of the filter frame 31 away from the workbench 1, the air inlet end of the vacuum pump 18 passes through the interior of the filter frame 31, and a material receiving frame 33 is fixedly connected to one end of the bottom of the filter frame 31 away from the workbench 1.

[0047] The side of the filter frame 31 away from the workbench 1 is fixedly connected to a limiting column 34, and one side of the limiting column 34 is fixedly connected to a metal sheet 36 through an elastic rope 35. The metal sheet 36 is made of magnetic metal and is slidably connected to the filter frame 31. The side of the elastic rope 35 close to the filter frame 31 is fixedly connected to a rubber block 37.

A baffle 39 is fixedly connected to the outer side of the rotating block 38 . A magnet block 40 is fixedly connected to the outer side of the rotating block 38 between the baffles 39 .

[0049] A second motor 41 is fixedly connected to one side of the inner wall of the filter frame 31 close to the workbench 1 , and an output end of the second motor 41 passes through the filter frame 31 and is fixedly connected to the rotating block 38 .

[0050] When in use, the air outside the workbench 1 is sucked into the control slot 7 by the air pump 18 through the filter frame 31, and the dust inside the air is blocked and attached to the filter screen 32 when passing through the filter screen 32. The metal sheet 36 is attracted by the magnet block 40 and attached to the surface of the rotating block 38. The second motor 41 drives the rotating block 38 to rotate. The metal sheet 36 is pushed by the baffle 39 and rotates with the rotating block 38. The elastic rope 35 is stretched. When the elastic force of the elastic rope 35 exceeds the attraction between the magnet block 40 and the metal sheet 36, the elastic rope 35 pulls the metal sheet 36 away from the rotating block 38. The metal sheet 36 is pulled by the elastic rope 35 to move toward the limit column 34 until the elastic rope 35 recovers its initial length. The magnet block 40 attracts the metal sheet 36 again and attaches it to the surface of the rotating block 38. The rubber block 37 is driven by the elastic rope 35 to slide on the surface of the filter screen 32. The rubber block 37 contacts and rubs with the filter screen 32, wiping the dust attached to the surface of the filter screen 32 and dropping it into the receiving frame 33, so that the equipment has the ability of automatic cleaning, and can continuously clean the surface of the filter screen 32 to prevent dust in the air from adhering to the filter screen 32 and clogging the filter screen 32.
