The invention discloses an electro-gas welding equipment positioning and deviation rectifying system and method based on optimized Kalman filtering, and relates to the technical field of Beidou navigation positioning.The system comprises an original data acquisition module which is deployed on electro-gas welding equipment and used for obtaining original positioning data of the electro-gas welding equipment in real time based on a Beidou navigation chip, the information is uploaded to a background server through a communication network; the filtering deviation correction module is used for receiving the original positioning data and sequentially executing rule judgment and optimized Kalman filtering processing to generate coordinates after deviation correction; the coordinate position marking module is used for marking the corrected coordinates on an electronic map for visual display; according to the method, the problems of positioning drift, matching errors, track jittering and the like of existing GNSS positioning in a complex factory environment are effectively solved by fusing rule judgment and a dynamic filtering technology, finally, the corrected coordinates are marked on an electronic map in real time, and visual monitoring and abnormal behavior early warning are supported.

The invention relates to a glass insulator connector, a machining mold and a machining method, the glass insulator connector comprises a metal shell, a glass insulator and a metal connecting piece, a connecting groove and an electric welding groove are formed in the two ends of the metal shell respectively, and the glass insulator is arranged in the metal shell and located between the connecting groove and the electric welding groove; the metal connecting piece penetrates through the glass insulator, the two ends of the metal connecting piece extend to the position between the connecting groove and the electric welding groove, the metal shell continuously extrudes the outer wall of the glass insulator, and the inner wall of the glass insulator is fixedly connected with the metal connecting piece. According to the scheme, the glass insulator is arranged in the metal shell, and the metal shell can continuously generate radial acting force on the glass insulator, so that the metal shell not only can be mutually connected and fixed with the glass insulator, but also can continuously provide centripetal acting force for the glass insulator; and the connection stability of the device is further improved.

The invention relates to the technical field of electronic and electrical welding, and discloses a method for enhancing the strength of an IMC layer of a welding spot in low-temperature welding and application. The method for enhancing the strength of the welding spot IMC layer in low-temperature welding comprises the following steps that S1, an electrode plating layer is prepared, specifically, the electrode plating layer is prepared on a copper base body electrode in a component welding area; s2, solder is applied, specifically, low-temperature solder is applied to the surface of the electrode plating layer; s3, welding: melting the low-temperature welding flux, and carrying out metallurgical reaction on the low-temperature welding flux, the electrode plating layer and the copper matrix electrode below the electrode plating layer, so as to form an IMC layer on a welding spot interface; according to the method, a traditional nickel-tin plating structure in the electrical / electronic industry is abandoned, the pure tin plating layer is directly prepared on the copper electrode, the thickness and the bonding strength of the welding spot IMC layer are effectively improved, the production cost is reduced, and the process compatibility is good.
