[0005] Furthermore, the lubrication rack is provided with a receiving and conveying assembly, the receiving and conveying assembly is used to receive the loading unit and the unloading unit, and the receiving and conveying assembly is used to support and convey the tire.

[0006] Furthermore, the lubrication rack is provided with a positioning assembly for positioning the tire, the positioning assembly includes two groups of positioning structures, and the two groups of positioning structures are respectively located on both sides of the lubrication rack; each group of positioning structures includes a driving member and a positioning rod, the driving member is installed on the lubrication rack, and the driving member is used to drive the positioning rod to rotate; the positioning rod can be rotated from a horizontal direction to an inclined direction, and the horizontal direction is parallel to the conveying direction of the receiving conveying assembly; when the positioning rod is in an inclined direction, the side of the positioning rod close to the feeding unit opens outward; the tire can pass between the two groups of positioning rods in the horizontal state, and can be blocked by the two groups of positioning rods in the inclined state.

[0007] Furthermore, the positioning rod is rotatably connected to a plurality of guide wheels along its length direction.

[0008] Furthermore, the lubricating oil spraying assembly includes a lubricating oil storage tank, an extraction pump and several groups of spray heads, wherein the extraction pump is used to extract the lubricating oil in the lubricating oil storage tank to the spray heads and spray them out, and the several groups of spray heads are fixed on the lubrication rack and located on the periphery of the airbag.

[0009] Furthermore, a lubricating oil collecting tray is provided at the lower part of the airbag, and the lubricating oil collecting tray is used to collect the lubricating oil, and the lubricating oil collecting tray is connected to the lubricating oil storage tank.

[0014] The working principle of this technical solution is:

[0015] Adjust the inclination angle of the positioning rod according to the tire model. The feeding unit transfers the tire to the receiving and conveying assembly, which conveys the tire. The positioning rod positions and adjusts the two sides of the tire and limits the position. When the in-place detector detects that the tire is in place, the receiving and conveying assembly stops operating. Then the extraction pump starts to extract the lubricating oil in the lubricating oil storage tank and sprays it from the nozzle, and the nozzles around start to spray the lubricating liquid on the airbag. After the spraying is completed, the jacking assembly starts to drive the jacking plate upward, and the jacking plate passes through the tire. When the first limit sensor detects that the jacking plate reaches the set position, the jacking assembly stops. The gas injection and suction assembly starts to inject gas into the airbag to expand the airbag. When the second limit sensor detects the top of the airbag, the gas injection and suction assembly stops injecting gas, and the jacking assembly starts to move downward. The downward movement of the jacking plate will press down the airbag, so that the surface of the airbag is in full contact with the tire lip to achieve a lubricating effect. When the first limit sensor detects that the position of the lifting plate reaches the specified position, the lifting assembly stops, and the gas injection and suction assembly starts to suck out the gas in the airbag, causing the airbag to deflate. After the gas is sucked out, the lifting assembly continues to drive the lifting plate down to its original position, and the first limit sensor detects the descending position of the lifting plate. The driving member drives the positioning rod to rotate so that the positioning rod is in a horizontal direction. Then the conveying assembly operates to convey the lubricated tire from between the positioning rods to the unloading unit, and the unloading unit conveys the lubricated tire to the next station.

The lifting plate 5 can pass through the middle hole of the tire 17, and the cross-sectional area of ​​the airbag 4 after expansion is larger than the middle hole of the tire 17.

[0031] The lubricating oil spraying assembly is used to spray lubricating oil to the outside of the airbag 4. The lubricating oil spraying assembly includes a lubricating oil storage tank 11, an extraction pump 12 and a plurality of groups of nozzles 14. The extraction pump 12 is used to extract the lubricating oil in the lubricating oil storage tank 11 to the nozzles 14 and spray it out. The plurality of groups of nozzles 14 are fixed on the lubrication rack 18 and are located on the outer periphery of the airbag 4. In this embodiment, a hollow connecting ring 13 is connected to the frame 3. The connecting ring 13 is connected to the output port of the extraction pump 12. The inner ring of the connecting ring 13 is provided with a plurality of groups of connecting holes corresponding to the nozzles 14 in the circumference direction. The nozzles 14 are installed in the connecting holes. A lubricating oil collecting pan 7 is provided at the lower part of the airbag 4.

[0034] The specific implementation process is as follows:

[0035] The inclination angle of the positioning rod 20 is adjusted according to the model of the tire 17. The feeding unit 1 transfers the tire 17 to the receiving and conveying assembly 19, which conveys the tire 17. The positioning rod 20 positions and limits the two sides of the tire 17. When the in-place detector detects that the tire 17 is in place, the receiving and conveying assembly 19 stops operating. Then the extraction pump 12 starts to extract the lubricating oil in the lubricating oil storage tank 11 and sprays it from the nozzle 14, and the nozzles 14 around start to spray the lubricating liquid onto the airbag 4. After the spraying is completed, the lifting assembly 9 starts to drive the lifting plate 5 upward, and the lifting plate 5 passes through the tire 17. When the first limit sensor 15 detects that the lifting plate 5 has reached the set position, the lifting assembly 9 stops.

When the second limit sensor 16 detects that the top of the airbag 4 is inflated to the right position, the gas injection and suction assembly 8 stops injecting gas, and the lifting assembly 9 starts to move downward. The downward movement of the lifting plate 5 will press the airbag 4 downward, so that the surface of the airbag 4 is in full contact with the tire 17 bead, achieving a lubricating effect. When the first limit sensor 15 detects that the position of the lifting plate 5 reaches the specified position, the lifting assembly 9 stops, and the gas injection and suction assembly 8 starts to suck out the gas in the airbag 4, so that the airbag 4 deflates. After the gas is sucked out, the lifting assembly 9 continues to drive the lifting plate 5 to descend to the original position, and the first limit sensor 15 detects the descending position of the lifting plate 5. The driving member 21 drives the positioning rod 20 to rotate, so that the positioning rod 20 is in a horizontal direction. Then the conveying assembly 19 operates to convey the lubricated tire 17 from between the positioning rods 20 to the unloading unit 2, and the unloading unit 2 conveys the lubricated tire 17 to the next station.
