The sleeve 12 passes through the limiting block 4. A cutting mechanism 3 for cutting the sleeve 12 is fixed to the moving block 7. The sleeve 12 is fed into the backrest mesh under the action of the three-axis moving mechanism 13. The fixing platform can be a simple fixture that conforms to the shape of the backrest mesh to fix it. The robotic arm is a conventional robotic arm that can achieve... The backrest mesh can be easily removed and inserted; the rubber sleeve 12 can be made from a roll of rubber sleeve 12. The rubber sleeve 12 is pulled out from the roll of rubber sleeve 12, conveyed by the conveying mechanism 2, and passed through the limiting block 4. When it is necessary to insert the rubber sleeve 12, the rubber sleeve 12 located in the limiting block 4 is inserted into the backrest mesh under the action of the three-axis moving mechanism 13. Then the cutting mechanism 3 is started to cut the rubber sleeve 12, thereby realizing the rubber sleeve insertion and cutting. Then the conveying mechanism 2 is started to make the rubber sleeve 12 continue to pass out of the limiting block 4, thus realizing the rubber sleeve 12 is cyclically inserted. Therefore, this invention eliminates the need for workers to manually assemble the rubber sleeve 12 at the end of each backrest mesh, improving efficiency and saving manpower, thus adapting to the needs of the rapid development of the modern automotive industry.

[0021] In this embodiment, the conveying mechanism 2 includes a first motor 1 fixed to the movable plate 21 and a synchronous belt drive assembly 19 connected to the output end of the first motor 1. The synchronous belt drive assembly 19 and the first motor 1 are located on opposite sides of the movable plate 21. The output end of the first motor 1 drives both synchronous belt drive assemblies 19 simultaneously via gear transmission.

The protruding end of the clamping protrusion 16 is flat, thereby improving the clamping quality of the rubber sleeve 12. The clamping member 5 has three clamping recesses 17 and clamping protrusions 16 in two adjacent clamping members 5, which are distributed in a cross pattern. The clamping axes of the three clamping members 5 are the same axis, which further improves the clamping quality of the rubber sleeve 12 and prevents the rubber sleeve 12 from sliding during movement and cutting.The three-axis moving mechanism 13 includes a y-axis moving assembly, an x-axis moving assembly 11, and a z-axis moving assembly 8 connected in sequence. The moving block 7 is fixed to the output end of the z-axis moving assembly. The y-axis moving assembly includes a moving plate 21 slidably connected to the worktable, a second motor 10 fixed to the bottom of the moving plate 21, a third gear 9 fixed to the output end of the second motor 10, and a rack fixed to the moving plate 21 and meshing with the third gear 9. The top of the moving plate 21 is connected in sequence to the x-axis moving assembly 11 and the z-axis moving assembly 8. Both the x-axis moving assembly 11 and the z-axis moving assembly 8 employ common lead screw and nut mechanisms, thereby enabling the moving block 7 to move in the x, y, and z directions, thus facilitating the insertion of the rubber sleeve 12 and the debugging of the device.

[0022] The working principle of this embodiment is as follows: When it is necessary to insert the rubber sleeve 12, the backrest mesh is first placed in the fixed platform and fixed. Then, the first motor 1 is started, and the synchronous belt transmission assembly 19 is started, so that the rubber sleeve 12 is inserted into the through hole 15 of the limiting block 4 and exits from the through hole 15. The rubber sleeve 12 will enter the clamping recess 17 and between the clamping recess 17. Then, the second pneumatic finger 6 is started, and the clamping recess 17 and the rubber sleeve are clamped. Then, the three-axis moving mechanism 13 is started, so that the rubber sleeve 12 is inserted into the backrest mesh. Then, the first pneumatic finger 14 is started, and the cutting blade 18 cuts the rubber sleeve 12. Then, the robot arm is started, the backrest mesh is removed, and a new backrest mesh is moved into the fixed platform. Then, the first motor 1 is started, thus realizing the cyclic application of the rubber sleeve 12. Therefore, this utility model eliminates the need for workers to manually assemble the rubber sleeve 12 at the end of each backrest mesh, improves efficiency and saves manpower, thereby adapting to the needs of the rapid development of the modern automobile industry.
