Description
Technical Field
The utility model relates to the technical field of automatic assembly and welding, in particular to a welding device for a fixed contact.
Background
In the electrical industry, static contacts exist in load switches of high-voltage, medium-voltage and low-voltage circuit breaker products, the types of the static contacts are various, but the static contacts are mainly composed of parts such as static contact pieces, static contacts and the like, and the static contacts are welded on the static contact pieces. The circuit breaker is closed or opened, and the fixed contact of the circuit breaker is contacted with or separated from the moving contact. When the circuit breaker is closed or opened, the static contact is required to be subjected to physical impact such as high voltage, high current and high temperature, so that the service life and the use effect of the circuit breaker are directly influenced by the capability of the static contact for bearing the high voltage, the high current and the high temperature.
In the prior art, most of static contacts are silver-based contacts or cadmium oxide contacts, and the static contacts are easy to oxidize in a humid air environment, so that the contact resistance is increased, the temperature is increased, and the long-term use risk of the circuit breaker is greatly increased. Silver has the properties of high electric conductivity and high heat conductivity, but has low melting point, soft quality, low Young's modulus, and poor fusion welding resistance and electric corrosion resistance. Therefore, the silver alloy is formed by adding elements into the silver, or the false alloy is formed by silver, metal and non-metal oxides, so that the fusion welding resistance and the electric corrosion resistance of the static contact can be improved. The mechanical property of the silver-based contact can be improved by adopting an alloying method, but the excellent electric conductivity and heat conductivity of part of silver can be sacrificed. Graphene, which is an emerging material, has ultra-high young's modulus, electrical conductivity, and thermal conductivity, and can replace silver-based contacts.
When assembling and welding the fixed contact of graphene material, the welding precision and the assembly precision requirement on the fixed contact are higher, and in the prior art, the fixed contact is mostly assembled and welded manually, the soldering flux and the fixed contact are manually placed on the fixed contact, the assembled fixed contact is placed in a welding jig, the welding jig is placed between an upper electrode and a lower electrode of a hot-melt welding device, the welding device is started to conduct electrifying and heating welding, and after the hot-melt welding is completed, the fixed contact can be circulated to the next procedure after being cooled. This approach has the following drawbacks: the efficiency of manually assembling the fixed contact is low, the thickness of the assembled fixed contact is relatively thin, the fixed contact and the fixed contact are easy to shift due to poor positioning performance of the welding jig in the process of moving the welding jig to the hot-melt welding equipment, and therefore the consistency of the quality of the finished product of the fixed contact is poor, the high requirements of assembling and welding the fixed contact made of graphene cannot be met, the fixed contact cannot be taken out immediately after welding is finished, and the production efficiency is low.
