During the rotation of the rotating shaft 104, it will also drive the rotating sleeve 106 to rotate. During the rotation of the rotating sleeve 106, the lifting plate 107 will move along the groove provided on the rotating sleeve 106. At the same time, due to the limiting effect of the limiting rod 108 on the lifting plate 107, the lifting plate 107 will reciprocate up and down with the rotation of the rotating sleeve 106.

[0042] When using the device, first install the device at a designated location, then place the door panel to be polished on the workbench 101, then start the motor 103 to drive the shaft 104 to rotate, the shaft 104 will drive the polishing pad 105 to rotate, and the mechanical arm 102 is controlled to drive the polishing pad 105 to move as a whole to polish the door panel. During the rotation of the shaft 104, it will also drive the rotating sleeve 106 to rotate, and the rotating sleeve 106 will drive the lifting plate 107 to move along the groove provided on the rotating sleeve 106 during the rotation. At the same time, due to the limiting effect of the limiting rod 108 on the lifting plate 107, the lifting plate 107 will reciprocate up and down with the rotation of the rotating sleeve 106. During the downward movement of the lifting plate 107, it will drive the pressing plate 110 to move downward through the fixing rod 109. During the downward movement of the pressing plate 110, the air at the bottom thereof will be squeezed and pushed into the air guide pipe 113 through the lower air outlet one-way valve 111. When the pressing plate 110 moves upward, the same is true. The pressing plate 110 will push the air at its top through The air outlet check valve 111 on the upper side is pushed into the air guide pipe 113, and the air guide pipe 113 will pass the air into the interior of the fixed block 114. The air passed into the interior of the fixed block 114 will push the blocking rod 201 downward, and the blocking rod 201 will drive the sliding plate 202 to move downward during the downward movement. When the blocking rod 201 moves to separate from the inner wall of the fixed block 114, the air passed into the interior of the fixed block 114 will enter the space at the top of the sliding plate 202. As the air continues to be input, the air in the fixed block 114 is The air will enter the second air guide pipe 115, and the second air guide pipe 115 will pass the air into the interior of the jet plate 116, and the jet plate 116 will eject the air from the jet hole at the bottom thereof. This design can blow the particle dust generated by the grinding pad 105 during the grinding process to the surroundings through the air ejected from the jet hole, thereby preventing some of the particle dust generated from remaining on the door panel. In the process of the grinding pad 105 reciprocatingly grinding, the particles will enter the bottom of the grinding pad 105, and scratch the door panel as the grinding pad 105 rotates, thereby affecting the aesthetics of the door panel.

[0043] In the process of the sliding plate 202 moving downward, it will compress the spring 1 203 and squeeze the air inside the fixed block 114, and the squeezed air will be pushed into the air duct 3 205, and the air duct 3 205 will pass the air into the interior of the fixed shell 207, and the air passed into the interior of the fixed shell 207 will push the sliding connecting rod 208 downward and stretch the spring 209, and the sliding connecting rod 208 will drive the shielding plate 210 to move downward in the process of moving downward, so that the bottom of the shielding plate 210 contacts the top of the door panel, and the bottom of the shielding plate 210 is made of soft material to prevent the shielding plate 210 from scratching the door panel when the robot arm 102 moves. This design can block the particulate dust blown around by the shielding plate 210, reduce the diffusion of dust, help keep the surrounding environment clean, and reduce the potential impact on the health of operators;

[0044] During the movement of the pressing plate 110, it will also inhale air into the interior of the robot arm 102 through the air inlet check valve 112, and can only inhale air through the air guide pipe 4 301. The air guide pipe 4 301 will inhale air from the collection box 302, and the collection box 302 will inhale air from the air guide cavity 306 in the baffle plate 210 through the air guide pipe 5 305. The air guide cavity 306 will inhale external air through the absorption port 307. During the process of the absorption port 307 inhaling air, it will also inhale the particle dust generated by grinding into the air guide cavity 306. The particles inhaled into the air guide cavity 306 will enter the interior of the collection box 302 through the air guide pipe 5 305. The particles entering the collection box 302 will remain in the collection box 302 due to the filtering effect of the filter plate 303. The particles remaining in the collection box 302 can be cleaned by opening the cleaning door 304. This design can collect most of the generated particles through the absorption port 307, reducing the need for frequent cleaning of the working area, saving manpower and time.

[0045] When the baffle plate 210 moves downward, it will drive the rotating rod 308 to rotate. During the rotation, the rotating rod 308 will drive the connecting rod 1 310 to move upward a certain distance. When the connecting rod 1 310 moves, it will drive the shielding ring 312 to move upward a certain distance through the connecting rod 2 311. At this time, the absorption port 307 will be exposed and can carry out normal work. After the baffle plate 210 is reset after the grinding work is completed, the shielding ring 312 will also be reset and then re-block the absorption port 307. This design can block the absorption port 307 after the grinding work is completed and the absorption port 307 no longer absorbs air, so as to prevent the particles remaining in the air guide cavity 306 and the air guide tube 5 305 after the work is completed from falling and falling out again from the absorption port 307.
