Problems solved by technology

[0005] The purpose of the present invention is to address defects such as air holes and cracks that are easily formed at the welding seams that exist in the welding technology used in the packaging of existing batteries and integrated electronic devices. High heat input during welding can easily cause welding deformation and high temperature during welding can easily damage the shell. To solve the problem of internal components, invent a method for electronic integrated device casing packaging or battery casing welding, and provide corresponding devices at the same time

Embodiment 1

[0033] Such as Figure 1-5 as shown,

[0034] A rolling friction connection method assisted by ultrasonic vibration, which comprises the following specific steps:

[0035] 1. According to the thickness of the shell and the size of the shell, a shell boss 8-1 and a shell stepped groove 8-2 are processed near the inner side of the shell 8 (such as Figure 4 ), or only one stepped groove 8-2 can be processed (such as Figure 5 ), a shell cover plate boss 9-1 is processed on the edge of the shell cover plate 9, and the shell cover plate is assembled in the stepped groove 8-2 of the shell to ensure that the edge of the shell cover plate boss 9-1 is in line with the There is a certain gap on the edge of the stepped groove 8-2. The edges of the housing cover plate 9 in contact with the housing stepped groove 8-2 are rounded to increase the filling volume of the plasticized material.

[0036] 2. Clean the shell boss 8-1, stepped groove 8-2, shell cover plate boss 9-1 and the edge ...
