Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone assembly, in particular to a mobile phone back cover rapid assembly device. Background Art

[0002] During the assembly process of a mobile phone, the back cover needs to be assembled on the middle frame of the mobile phone. On traditional mobile phone back cover assembly equipment, the back cover is placed on the middle frame and the material is loaded at the same time. The equipment then grasps and corrects the position of the back cover and the middle frame through positioning, and assembles the two. However, when the equipment grasps the back cover, the middle frame is under the back cover. Since the middle frame is not a hollow structure, the support force for the back cover is insufficient. If the downward pressure of the equipment is too large when grasping, the back cover and the middle frame are easily deformed, resulting in subsequent poor assembly. Therefore, it is necessary to produce a mobile phone back cover rapid assembly equipment to solve the above problems. Utility Model Content

[0006] Further description of the utility model: The fine-tuning drive assembly includes a mounting plate, a vertical slide, a movable bracket, a Z-axis drive component, an X-axis drive component, a Y-axis drive component, a rotation drive component and a drive base.
