Circuit board welding gun achieving automatic feeding

Abstract

The invention discloses a circuit board welding gun achieving automatic feeding. The circuit board welding gun structurally comprises an electric welding head, a wire wiping structure, a front end, abody, an automatic wire discharging device and a handle. The front end and the handle are mounted at the two horizontal ends of the body correspondingly. The automatic wire discharging device is mounted in the body. The electric welding head is mounted on the other side, opposite to the body, of the front end and cooperates with the wire wiping structure. A rotating shaft is sleeved with the circuit board welding gun through a tin wire barrel, after a motor is powered on to rotate, a tin wire is conveyed out from wire outlets of housings, the tin wire comes out from the electric welding head after being guided by the wire wiping structure, heating is achieved on the electric welding head together, and tin and heating are achieved together; and through the housings on the two sides of the wire outlet, one housing is warped outwards, the other end is in an outward semicircular shape, the two ends of each housing are smooth and free of burrs, tin wire discharging is smoother, and the problems that tin wires are broken due to mutual friction, and wires cannot be fed smoothly cannot happen.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to an automatic feeding circuit board welding torch. Background technique [0002] Circuits are put into use in the market after being clad with copper, tinned and assembled, and most of the old circuit boards that are recycled are due to the lack of tin materials and need to be repaired by spot welding. For a small number of repairs, most All of them are manually repaired by spot welding, that is, tin material with one hand and welding gun with the other hand. This repair method is easy to cause accidental injury, and the accuracy of tin material staining is low. At present, there are also circuit board welding guns with automatic feeding on the market, and the internal parts are complicated. The feeding is prone to jamming, and the outlet is prone to blockage due to the temperature rise. After one use, the tin wire cannot be sent out after the second use. Contents of the invention ...

At present, there are also circuit board welding guns with automatic feeding on the market, and the internal parts are complicated. The feeding is prone to jamming, and the outlet is prone to blockage due to the increase in temperature. After one use, the tin wire cannot be sent out after the second use.
