Description

Technical Field

[0002] During the tire and rim assembly process, grease needs to be applied to the inner edge of the tire and the outer edge of the rim. The current production process uses a manual brush to apply grease. The disadvantages of manual grease application are low efficiency and the amount of grease application requires workers to master proficiency. Too much grease will cause grease omission and waste, while too little will lead to uneven application. In the later tire installation process, it will cause destructive damage to the rubber tire assembly surface, resulting in the risk of air leakage in the assembled tire. The production process of manual grease application is inefficient and has a low compatibility with the automated wheel rim tire assembly line, and cannot effectively exert the efficiency of the automated production line. Therefore, automated application technology is now mostly used to ensure product uniformity.

Limiting structures are provided on both sides of the top of the base plate, which are used to clamp the tire and ensure that the tire can rotate between the two limiting structures. A slide groove is opened in the center of the top of the base plate, and a driving mechanism is installed inside the slide groove to drive the tire to rotate; however, in actual applications, due to the use of spraying, the control requirements for the rotation speed and spraying flow rate during the spraying process are relatively high, and the lubricating liquid will splash during the spraying process, affecting the neatness, and it is difficult to control the distribution of the lubricating liquid.
