Problems solved by technology

[0002] The welding of BUSBAR in the electronics industry usually uses electric welding machines, and the flatness of the welding head has a particularly obvious impact on the welding effect. The flatness of the new welding head itself can often meet the requirements, but after a period of subsequent use, it is inevitable If the surface is polished and cleaned, the flatness of the welding head will be affected at this time, and various welding defects will occur in the welding of subsequent products. If the welding head is scrapped because of this, it is not a small waste

Embodiment Construction

[0011] A welding process to improve the flatness of the welding head: add a layer of aluminum sheet between the welding head and the welding product, the lower plane of the aluminum sheet is close to the solder, and the welding head transfers the heat for welding to the solder through the aluminum sheet, It enables the solder to weld the products that need to be welded into a whole.

[0012] The aluminum sheet is specifically an aluminum sheet with a thickness of 0.2mm;

[0013] The solder paste is printed in advance on the position where the nut needs to be welded on the product, and then the nut and the product are manually pressed together by using the viscosity of the solder paste, and then the product is turned upside down on the jig with the nut facing down, and then the aluminum sheet is placed on the back of the product. Then drive the welding head for welding;

[0014] The aluminum sheet is provided with an avoidance hole corresponding to the protruding position of t...

Abstract

The invention provides a welding technology for improving the flatness of a welding head. Unnecessary diffusion of soldering tin can be avoided, and poor welding caused by unflatness of the welding head can also be avoided. An aluminum sheet is added between the welding head and a welded product, the lower plane of the aluminum sheet is tightly attached to soldering tin, the welding head transfersheat for welding to the soldering tin through the aluminum sheet, and therefore the welded product can be welded into a whole through the soldering tin.

Description

technical field [0001] The invention relates to the technical field of BUSBAR welding, in particular to a welding process for improving the flatness of a welding head. Background technique [0002] The welding of BUSBAR in the electronics industry usually uses electric welding machines, and the flatness of the welding head has a particularly obvious impact on the welding effect. The flatness of the new welding head itself can often meet the requirements, but after a period of subsequent use, it is inevitable If the surface is polished and cleaned, the flatness of the welding head will be affected at this time, and various welding defects will occur in the welding of subsequent products. If the welding head is scrapped because of this, it is not a small waste. Contents of the invention [0003] In view of the above problems, the present invention provides a welding process for improving the flatness of the welding head, which can not only prevent unnecessary diffusion of so...
