[0002] Frameless doors, as a unique design element, have gradually increased in application in the market in recent years, especially in the field of new energy vehicles. Frameless doors have become a plus item for vehicle styling, and the assembly rate is rapidly increasing. Frameless doors eliminate the traditional frame in appearance, allowing seamless fitting between the door and the body, thereby improving the fashion and aesthetics of the vehicle.

[0003] Because frameless doors do not have a frame, the difficulty of door glass assembly increases. The common frameless door glass assembly method is to achieve positioning through a complex pneumatic control tooling. The specific scheme is as follows: the glass lifter is self-positioned and assembled with the sheet metal hole on the door sheet metal assembly through the stud on the guide rail, then the door sheet metal assembly with the installed glass lifter is positioned on the tooling, then the tooling is operated to hold the door and the glass, the glass clamp of the lifter is tightened and the glass is released.
