The buffer spring 43 is arranged along the length direction of the workbench 2.

[0041] With reference to Figure 1 The dust suction assembly 3 is used for sucking dust of the components on the pneumatic slide. The dust suction assembly 3 is installed on the workbench 2 and arranged close to the side edge of the workbench 2. The dust suction assembly 3 comprises a dust suction cavity 31, a friction rod 32, a transmission assembly 33, a dust scraping plate 34 and a storage cavity 35. The dust suction cavity 31 is detachably connected to the side edge of the workbench 2 away from the clamping assembly 4. The dust suction cavity 31 is arranged as a hollow cylinder. The dust suction cavity 31 is provided with a dust suction groove 311 on the side away from the workbench 2. The inner wall of the dust suction cavity 31 is uniformly provided with fixed teeth 312. The inner wall of the dust suction cavity 31 is covered with dust suction cotton 313. The fixed teeth 312 are inserted into the dust suction cotton 313 to fix the dust suction cotton 313 inside the dust suction cavity 31. The end of the dust suction cavity 31 away from the workbench 2 is provided with a replacement groove 314. The inner wall of the replacement groove 314 is hingedly connected with a sealing cover 315.

[0042] With reference to Figure 2 and Figure 3 The friction rod 32 is rotatably connected to the inside of the dust suction cavity 31 along the axial direction of the dust suction cavity 31. The friction rod 32 extends to the outside of the dust suction cavity 31 and is connected with the transmission assembly 33. The friction rod 32 comprises a metal rod 321 and an insulating rod 322. The metal rod 321 is located inside the dust suction cavity 31. A plurality of friction branch rods 323 are fixedly connected to the peripheral surface of the metal rod 321. The metal rod 321 is integrally formed with the friction branch rods 323. The ends of the friction branch rods 323 away from the metal rod 321 abut against the dust suction cotton 313. The end of the insulating rod 322 close to the metal rod 321 is provided with a connecting hole 324. The inner wall of the connecting hole 324 is tightly attached with anti-skid rubber 325. The metal rod 321 is inserted into the connecting hole 324 and abuts against the anti-skid rubber 325, so as to connect the metal rod 321 with the insulating rod 322. The insulating rod 322 is located outside the dust suction cavity 31 and connected with the transmission assembly 33.

[0043] When the cylinder body 1 pushes the workbench 2 to transport the articles, the transmission assembly 33 continuously drives the friction rod 32 to rotate, so that the friction supporting rod 323 continuously rubs against the dust absorption cotton 313, thereby generating static electricity, so that the dust on the workbench 2 and the cylinder body 1 is adsorbed on the dust absorption cotton 313, so that the workbench 2 and the cylinder body 1 are kept clean, and the damage of the parts caused by the dust entering the connection between the workbench 2 and the cylinder body 1 and the inside of the cylinder body 1 is reduced.

[0044] With reference to Figure 4 , the transmission assembly 33 is used to drive the friction rod 32 to rotate, so that the friction supporting rod 323 rubs against the dust absorption cotton 313, thereby generating static electricity to adsorb the dust. The transmission assembly 33 comprises a transmission rack 331 and a transmission gear 332. The side of the cylinder body 1 connected with the workbench 2 is provided with a mounting groove 14 along the length direction. The transmission rack 331 is located in the mounting groove 14. The transmission gear 332 is sleeved on the end of the insulating rod 322 away from the metal rod 321 and is fixedly connected with the insulating rod 322. The transmission gear 332 is engaged with the transmission rack 331.

[0045] When the workbench 2 slides under the pushing of the cylinder body 1, the transmission gear 332 slides on the transmission rack 331 along with the workbench 2 and continuously rotates, thereby driving the friction rod 32 to continuously rotate in the dust absorption cavity 31, so that the friction supporting rod 323 continuously rubs against the dust absorption cotton 313 to generate static electricity.

[0046] With reference to Figure 2 , the dust scraping plate 34 is located in the inside of the dust absorption cavity 31. The end of the dust scraping plate 34 is rotatably connected with the end of the metal rod 321 away from the replacement groove 314, and the side edge of the dust scraping plate 34 abuts against the inner wall of the dust absorption cavity 31. A rebound torsion spring 341 is arranged at the connection between the dust scraping plate 34 and the metal rod 321. When the dust scraping plate 34 is pulled to the dust outlet groove 316 by the traction rope 36, the buffer spring 43 can provide directional force for the dust scraping plate 34, so that the dust scraping plate 34 rotates in the opposite direction to the original position, to facilitate the next dust scraping. The side wall of the dust absorption cavity 31 close to the dust scraping plate 34 is provided with a dust outlet groove 316. The side edge of the outside of the dust absorption cavity 31 close to the dust outlet groove 316 is connected with a storage cavity 35. The storage cavity 35 is communicated with the dust absorption cavity 31 through the dust outlet groove 316.

[0047] The end of the dust scraping plate 34 away from the metal rod 321 is connected with the traction rope 36. The traction rope 36 extends to the outside of the dust absorption cavity 31, and the traction rope 36 is connected with the end of the buffer spring 43 close to the mounting plate 45.

[0048] When the buffer spring 43 is stretched, the traction rope 36 can be pulled, the traction rope 36 drives the dust scraping plate 34 to rotate, the dust scraping plate 34 abuts against and slides on the inner wall of the dust suction cavity 31, dust falling to the bottom in the dust suction cavity 31 can be hung at the dust outlet groove 316, so that the dust falls into the storage cavity 35, thereby effectively collecting the dust and reducing the situation that the dust flies in the air and falls on the workbench 2 and the cylinder body 1.

[0049] The storage cavity 35 is detachably connected to the workbench 2, the storage cavity 35 is provided with a fixing block 351 on the side wall close to the fixing plate 41 along the width direction of the fixing plate 41, the fixing plate 41 is provided with a fixing groove 411 on the side wall close to the fixing block 351 along the width direction, and the fixing block 351 is located in the fixing groove 411.

[0050] When the storage cavity 35 is full of dust, the storage cavity 35 can be taken off from the workbench 2, and the storage cavity 35 is cleaned.

[0051] The implementation principle of the cross roller guide rail 12 pneumatic sliding table is that when the cylinder body 1 drives the workbench 2 to transport articles, the transmission assembly 33 constantly drives the friction rod 32 to rotate, so that the friction support rod 323 constantly rubs on the dust suction cotton 313, thereby generating static electricity, the dust on the workbench 2 and the cylinder body 1 is adsorbed on the dust suction cotton 313, so that the workbench 2 and the cylinder body 1 remain clean, and the situation that the dust enters the connection between the workbench 2 and the cylinder body 1 and the inside of the cylinder body 1 is reduced.

[0052] The above are preferred embodiments of the application, which do not limit the protection scope of the application, so: any equivalent changes made on the basis of the structure, shape, principle of the application should be covered in the protection scope of the application.
