Welding machine

Abstract

The invention relates to a welding machine which comprises a machine seat, and the machine seat is provided with a working platform. The design point is as follows: a sliding seat moving relative to the working platform is arranged on the working platform, the sliding seat is provided with a first welding heat used for welding, the machine seat is provided with an intermittent drive device used for driving the sliding seat to move and a control circuit connected with the first welding head, a screw rod assembly for transmission is arranged between the intermittent drive device and the sliding seat; a sliding plate moving up and down is arranged below the working platform, the machine seat is also provided with a second intermittent drive device, the second intermittent drive device and the sliding plate are transmitted by a second screw rod assembly, the upper end of the sliding plate is provided with a second welding head, and the second welding head is connected with the control circuit. The invention aims at providing the welding machine which controls the welding head to move with high precision and can carry out two-surface welding with high welding precision.

Description

[technical field] [0001] The invention relates to a welding machine, in particular to an instantaneous heating welding machine for welding wires and connectors, copper sheets or PCB boards. [Background technique] [0002] At present, the traditional wire welding method is pneumatic thermocompression welding, which uses the movable push rod of the cylinder to drive heating elements such as electric heating wires, electric heating tubes, and electric heating plates for welding. The heat generated by the welding head heats the tin at the position to be welded After melting, the wire can be firmly welded to the gold finger, copper sheet or PCB board of the connector after the tin is cooled. This traditional hot-press welding has the following disadvantages: First, the control accuracy of the movable push rod of the cylinder is not high, and the use of the push rod to directly drive the welding head to heat is likely to cause insufficient pressure and insufficient heat fusion, wh...

Problems solved by technology

This traditional hot-press welding has the following disadvantages: First, the control accuracy of the movable push rod of the cylinder is not high, and the use of the push rod to directly drive the welding head to heat is likely to cause insufficient pressure and insufficient heat fusion, which affects the firmness of the connection or the welding head moves too far The gold finger, copper sheet or PCB and other workpieces that have crushed the connector have a low yield rate; secondly, during normal processing, the use of push rods to directly drive the heating component to heat can only be heated and melted once, that is, the welding head can only be heated once. Press down in place and then melt, which ignores the influence of the height of the tin point at the solder joint on the soldering, resulting in poor spot welding quality and easy loosening
