Fuse welding machine

Abstract

The invention provides a fuse welding machine, and belongs to the technical field of fuse tube manufacturing. The problem that the welding quality of an existing fuse and a metal cap is poor is solved. The fuse welding machine comprises a rack, a rotary table arranged on the rack, a fuse tube clamping mechanism arranged on the rotary table, and a fuse tube sleeving mechanism, a fuse threading mechanism, a first laser welding mechanism, a first tin breaking and feeding device, a fuse tube overturning mechanism, a second laser welding mechanism, a second tin breaking and feeding device and a fuse tube discharging mechanism which are sequentially arranged around the rotary table; the fuse welding machine is characterized in that the first laser welding mechanism and the second laser welding mechanism each comprise a support and a laser welding machine head arranged on the support, the laser welding machine heads are arranged downwards, and the laser welding machine heads can emit annular laser beams. The structure of the fuse welding machine obviously improves the welding quality of a fuse and a metal cap.

Description

technical field [0001] The invention belongs to the technical field of fuse manufacturing, in particular to a fuse welding machine. Background technique [0002] The fuse tube is an electrical component installed in the circuit to ensure the normal and safe operation of the circuit. When the circuit fails or is abnormal, the current will continue to rise, and the fuse will rise to a certain height and at a certain time when the current is abnormal. Self-fuse cuts off the current, thereby protecting the safe operation of the circuit. as in the attached figure 1 As shown, the fuse sleeve includes a glass tube 20, metal caps 21 are provided at both ends of the glass tube 20, and a through hole 22 is provided in the middle of the two metal caps 21. Traditional fuse tubes are generally manufactured manually, specifically: Pass the fuse 23 sequentially through the through holes 22 on the two metal caps 21, so that the fuse 23 is inserted into the glass tube 20, and then solder t...

Problems solved by technology

[0004] During the manufacturing process of the above-mentioned fuse, the end of the fuse wire and the metal sleeve are connected by laser welding. Specifically, the laser heats the metal sleeve to raise the temperature on the metal sleeve to a temperature at which the tin wire can melt, and then Place the tin wire on the heating area of ​​the metal sleeve, and the tin wire will melt immediately so that the fuse wire and the metal sleeve are welded together. When traditional laser welding is used, the laser spot formed by the laser is dot-shaped, so the heating position on the metal sleeve It is also point-shaped, and the tin wire is in direct contact with the point-shaped heating position, so that the tin wire melts and forms a block of solder. The solder cannot wrap the fuse, and there is a problem of virtual soldering. The fuse is prone to short circuit during use. risks of
