Description

Capping device for spot welding of laser capping

Technical Field

The utility model relates to a laser closing cap is capping device for spot welding belongs to laser welding technical field.

Background

Extreme environments such as aerospace for precision electronic structures such as bare chips on electronic products suffer damage easily, thereby reduce product life, can appear endangering operating personnel personal safety owing to the harm of chip even. In order to ensure the use of electronic products in extreme environments, the electronic products are packaged by laser through a gas-tight tube shell. The laser package is widely used for packaging electronic devices, and mainly uses laser with the power of 500-3000W to continuously hit the lap joint of a package tube shell and a cover plate at a certain frequency, and the high temperature generated by the laser enables the tube shell and the cover plate to mutually permeate after being melted so as to form a continuous welding bead. When the tube shell and the cover plate are welded by using laser, annular welding such as a 'mouth' shape is always formed from one point, the mode ensures that the local heat of the side which is welded firstly is very high, generally, thousands of degrees exist, the side which is not welded is still at normal temperature, the temperature difference of the cover plate is very large, and great thermal stress is generated to cause the warping phenomenon of the other side which is not welded of the cover plate, so that the air tightness of a product and the smoothness of the matching of an assembly surface are reduced, and even the cover plate and the tube shell can not be combined, therefore, the relative position is fixed by adopting uniform spot welding at the periphery of the joint of the cover plate and the tube shell, and then continuous sealing welding is carried out. Although the difference of the thermal stress generated in the spot welding fixing process is smaller than that generated in continuous welding, the warping deformation generated on the cover plate is still obvious, the general solution is to use a mechanical pressing mode to press the cover plate, and how to conveniently and quickly press the cover plate is an important step in laser welding.

The traditional mode of solving the problem of complaint is to design a special pressing block, according to the encapsulation tube shells of different sizes and types, design a pressing block which is similar to the cover plate in appearance but slightly smaller than the cover plate and has a certain height and gravity, and utilize the self gravity of the pressing block to press the warping behavior of the cover plate in laser seam welding. However, this method has several disadvantages: 1. the economic efficiency utilization rate is low, different cover plates need to be provided with a pressing block, and the pressing blocks are not universal when different pipe shells are packaged; 2. the pressing effect is not obvious, the height of a focusing point from the laser light emitter to the packaging tube shell is limited, so that the size of the pressing block is limited, the volume of the pressing block is determined by the light condensation height and the shape of the cover plate, the gravity of the pressing block depends on materials, the pressure provided by the pressing block is limited, and the pressure provided by the pressing block in some sealing covers is insufficient.
