Skirt removal method, case processing method, case and electronic device

Abstract

The invention relates to the field of electronic device parts and machining methods thereof, in particular to a skirt removal method, a shell body machining method, a shell body and an electronic device. According to the skirt removal method, a vacuum suction device is adopted for sucking the surface, opposite to the skirt, of a sheet metal shell; and a numerically-controlled machine tool is adopted for removing the skirt. According to the shell body machining method, sheet metal is adopted for forming the sheet metal shell; intromode injection molding is carried out on the sheet metal shell to form a plastic part connected with the sheet metal shell; and the skirt is removed by adopting the skirt removal method for the sheet metal shell. Because the sheet metal shell is fixed through vacuum suction, the whole surface, opposite to the skirt, of the sheet metal shell low in strength can be sucked to be flat, and by using the flat sucked surface as the basis for skirt machining, it can be guaranteed that the size of the sheet metal shell is accurate, in other words, it is guaranteed that the height dimension of the shell body is accurate. The shell body is machined by adopting the shell body machining method, the electronic device comprises the shell body, and the height dimension of the shell body and the height dimension of the electronic device are accurate.

Description

technical field [0001] The invention relates to the field of electronic device parts and processing methods thereof, in particular to a method for removing the skirt of a thin-plate metal shell, a shell processing method, the shell and an electronic device. Background technique [0002] In order to ensure the precise height and size of the metal shell and facilitate assembly, the height of the metal shell will be higher than the actual product size by a certain margin, and the higher part is the skirt. For example, in the shell processing process, before injection molding, the metal shell includes a skirt, and after injection molding, the skirt is removed by a numerical control machine tool (CNC) to ensure that the size of the metal shell is accurate, that is, to ensure the shape of the shell True to size. For the current thicker metal shell, when processing the skirt edge positioning, use four points on the four corners of the product inner cavity, take the average height ...

AI Technical Summary

Problems solved by technology

This method of skirt removal often has large tolerances in the reference plane due to shell deformation, resulting in inaccurate dimensions of the finished metal shell

Furthermore, in the current process of stamping and forming metal shells by sheet metal, when the above method of removing the skirt is used for thinner metal shells, the above problems are more likely to occur
