A new energy vehicle plug-in fuse assembly process

Abstract

The invention relates to an assembly process of the plug-in fuse of a new energy vehicle, which comprises the following steps: S1, a process of conveying a material belt; S2, a process of separating asingle strip-shaped electric conductor from the material belt; S3, a process of feeding the strip-shaped electric conductor; S4, a process of bending the strip-shaped electric conductor into a U-shaped electric conductor; S5, a process of assembling an insulation shell and the U-shaped electric conductor into an assembly I and shaping the assembly I; S6, a process of detecting the assembly I andassembling the assembly I and an end cover into an assembly II; S7, a process of conveying the assembly II; S8, riveting and fixing the assembly II into a fuse assembly; S9, a process of marking the fuse assembly; and S10, a process of collecting a finished product. According to the invention, the accessories of the fuse assembly are combined together according to a set sequence, so that the manual assembly is reduced, the assembly quality and efficiency of the fuse assembly are improved, defective products are removed in time, the qualification rate of the fuse assembly is improved, and the fuse assembly has a good market application value.

Description

technical field [0001] The invention relates to the technical field of fuse assembly technology, in particular to a new energy vehicle plug-in fuse assembly technology. Background technique [0002] Fuse refers to an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high-voltage and low-voltage power distribution systems, control systems, and electrical equipment. As short-circuit and over-current protectors, fuses are one of the most commonly used protection devices; The demand for electrical components is also increasing rapidly. In the power system circuit of new energy vehicles, fuses are used to protect the circuit and...

Problems solved by technology

[0003] At present, the parts of the fuse are mainly assembled by hand, but the middle part of the conductor is the fuse / melt. At this stage, when making the conductor, the copper plate is first cut according to the set shape, The size and spacing are punched into strips containing multiple conductors arranged at equal intervals, and the surface area of ​​each conductor reaches the use standard. The adjacent two conductors in the strip are connected by connecting strips, and then passed through The manual cutting machine first separates the material strip into a single conductor, and then bends the strip conductor into a U-shaped conductor through a manual combination bending machine, and then inserts the U-shaped conductor into the insulating shell through a manual combination pressing machine , and finally the end cover and the insulating case are firmly fixed by a riveting machine to form a fuse assembly. Due to the instability of manual assembly, it is easy to cause the conductor to be bent in place and not inserted into the insulating case, etc., which will lead to fuse failure. The quality cannot be guaranteed, the rate of defective products is high, and the efficiency of manual assembly is low, which cannot meet the large demand of the market. Therefore, the existing assembly process has defects and needs to be improved
