Description
Technical Field
The utility model belongs to the field of laser welding equipment, and particularly relates to fuse laser welding equipment.
Background
The fuse is widely applied to high-low voltage distribution systems, control systems and electric equipment, and comprises a battery pack of an electric automobile and a control system, and is used as a protection device for short circuit and overcurrent. The core component is the fuse, and the fuse can be correctly fused, so that the realization of the protection function of the fuse is ensured.
The welding of the fuse piece and the connecting terminal belongs to a key process in the manufacturing process of the fuse, the welding quality of the fuse piece and the connecting terminal directly influences the electrical performance of the fuse, and good welding of the fuse piece and the connecting terminal ensures that the fusing point of the fuse piece is arranged at the narrow neck position of the fuse piece designed by us under the conditions of short circuit and overcurrent, and the welding quality directly determines whether the protection function of the fuse can be accurately and timely executed.
In the fuse, the fuse piece material is oxygen-free copper and pure silver, and thickness is 0.1mm to 0.3mm generally, and fusing characteristic relies on the size assurance of several rows of round holes on the fuse piece, because the fuse piece is lighter and thinner soft, and the connecting area after punching the hole is limited in addition, easily impaired deformation when artifical equipment can influence the electrical property of fuse, and fuse piece and terminal positioning accuracy are difficult to guarantee by manual operation in addition.
In the current fuse industry, resistance welding is generally used for welding the fuse piece and the connecting terminal, and because of large welding pulse current, the resistance welding can lead to local power grid fluctuation, and a plurality of welding machines can mutually influence when working simultaneously, so that welding quality fluctuation is generated. And the welding electrode is extremely easy to wear, so that the quality fluctuation of the welding electrode is relatively large.
The weld quality judgment after welding the fuse piece and the terminal is difficult to detect by using a non-destructive detection means, and the welding seam detection means such as ultrasonic waves is low in lap welding efficiency and low in detection accuracy for the thin sheet with a shallow melting pool such as the fuse piece. The industry generally relies on visual judgment at present, and a large misjudgment risk exists.
