The factors affecting the assembly force of conveyor belt in clearance fit assembly line include the relative position precision before assembly, the edge state of assembly parts such as chamfer edge, the rough appearance of assembly process system, the stiffness of assembly line process system, the clearance of connection shape and the friction coefficient between assembly parts.

In the case of parallel to the assembly shaft, the assembly force of the assembly line exists on the contact surface. The main factors affecting the assembly quality of the assembly line conveyor belt are: assembly quality of the assembly line conveyor belt, friction coefficient of the equipment with the foreman and the matching parts, chamfering and flexibility of the assembly system perpendicular to the axial direction, etc. The method does not consider the flexibility of the assembly line conveyor belt, but calculates the normal clamping force and axial thrust of the workpiece according to the general statics law.

The assembly line is designed to increase labor productivity with few workers. The design of the assembly line varies from person to person, which directly affects the use effect and efficiency of the assembly line. Each major manufacturer adopts the assembly line. The layout of the assembly line should be combined with modern management and how to manage it should be considered. The high-level management mode is directly related to the assembly line layout.
