High-frequency welding induction gun head and welding gun with gun head applied

Abstract

The invention relates to a high-frequency welding induction gun head and a welding gun with the gun head applied. The welding gun comprises a gun body, a drive mechanism and the gun head; the gun head comprises a connection cover and a casing pipe; the gun body comprises a gun head base, a welding assembly and a control assembly; the welding assembly is installed on the front end portion of the gun head base and comprises a magnetic conductive bar and an electromagnetic induction coil surrounding the magnetic conductive bar; the control assembly is arranged on the rear side of the welding assembly and comprises a control unit and a pressure sensor arranged on the rear side of the control unit; the front end of the control unit is in abutting connection with the magnetic conductive bar; and the rear end of the control unit is in non-contact connection with the pressure sensor. Shaping and fusion welding on a post terminal are completed synchronously in the welding process of a storage battery connecting terminal through cooperation of a high-frequency electromagnetic induction heating mode and lifting movement of the gun head, the traditional welding procedure is simplified, and full-automatic and mechanical welding production of the storage battery connecting terminal is easily achieved by being matched with a mechanical arm.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a high-frequency welding induction gun head used for automatic welding of storage battery terminals and a welding gun using the gun head. Background technique [0002] Recently, in the field of battery processing, the terminal is fixedly connected to the positive and negative poles on the battery by welding. The traditional method is to weld the terminal with a welding torch combined with a welding wire. This welding method has a complex structure and cumbersome operation. , low efficiency and poor welding quality, high product failure rate. [0003] In addition, the lugs after welding by the above method are uneven and prone to bulges, which need to be cut and removed manually to avoid short circuits, but the welding process is increased, the working time is prolonged, and the work efficiency is reduced. There are safety hazards in the process. [0004] C...

Problems solved by technology

[0005] According to the applicant’s response, although the above technical solution uses the change of the contact force between the stud and the pressure sensor to control the motion of the stud to perform precise welding, it solves the problem that the stud feeding pressure cannot be detected during the feeding process of the existing stud welding torch. The defect that the movement of the stud cannot be controlled, but there are still some problems. First of all, the welding method still uses the traditional arc welding, which needs to be used with welding wire, which is costly and difficult to operate. When welding, it is necessary to maintain a stable welding current for a period of time to form a certain molten pool to complete the welding. The temperature cannot be accurately controlled in sections, and it is impossible to locally soften, shape, and weld the battery poles. Therefore, this welding method cannot be applied to battery wiring. Soldering of terminals
