An automatic wire laser soldering machine

Abstract

The invention discloses an automatic wire laser soldering machine, which comprises a machine base, a fixing frame is fixedly installed on the base, a sliding rail is arranged on the fixing frame, a laser generator is slidably installed on the sliding rail, and a central surface of a rotating workpiece disc is installed There is a solder paste tank, a number of solder joint grooves are arranged on the edge of the workpiece plate, the solder joint groove and the solder paste tank are connected by a hose, a workpiece clamping plate is arranged on the outside of the workpiece plate, and a top of the solder paste tank is installed Small cylinder, the pressure rod of the small cylinder is inserted into the solder paste tank. The invention can squeeze the solder paste in the solder paste tank through the hose and conduct it into the solder joint slot under the action of the pressing rod at the bottom end of the small cylinder, and the solder paste contacts the surface of the workpiece, which can play the role of pre-injecting the solder paste in advance. Compared with manual spot welding, the soldering efficiency is higher, and the instant heating of the solder paste is avoided, so that the solder paste can be kept at room temperature at first, and the quality of the solder paste can be avoided.

Description

technical field [0001] The invention relates to a laser soldering machine, in particular to an automatic wire laser soldering machine. Background technique [0002] Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple treatment after welding, high welding seam quality, no pores, precise control, small focusing spot, high positioning accuracy, easy to realize automation, and general In the soldering process, most of the soldering is performed by rotating the workpiece, and the solder paste is synch...

AI Technical Summary

Problems solved by technology

It is a new type of welding method, mainly aimed at the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, lap welding, sealing welding, etc., with high depth-to-width ratio, small weld width, and small heat-affected zone. The deformation is small, the welding speed is fast, the weld seam is smooth and beautiful, no treatment is required or only simple treatment is required after welding, the weld seam quality is high, no porosity, can be precisely controlled, the focusing light spot is small, the positioning accuracy is high, and it is easy to realize automation. Most of the soldering process is performed by rotating the workpiece. The solder paste is synchronized with laser spot welding for welding processing, or by adjusting the displacement of the welding head for soldering. When processing many small workpieces, manual spot welding is required, and the solder paste cannot be soldered again. During the process, it is pre-introduced into the spot welding groove, and the processing efficiency is relatively slow
