Abstract

The invention discloses a novel pressure welding system. The novel pressure welding system comprises a cleaning unit for cleaning impurities on surfaces of to-be-machined workpieces and a pressure welding unit for performing pressure welding operation on the workpieces, wherein the pressure welding unit comprises a rack, a workbench arranged on the rack, a pressure welding power arm capable of acting along the rack up and down, a pressure welding assembly connected with the pressure welding power arm, a heating structure for heating the pressure welding assembly as well as a first drive part for driving the pressure welding power arm to act up and down; the pressure welding assembly comprises a pressure welding head and a pressure dispersion part connected to the pressure welding power arm through an elastic part, and in the initial state, the pressure dispersion part is located below a pressure welding head and above the workbench. The novel pressure welding system can effectively disperse pressure applied by the pressure welding head to the workpieces, prevent workpiece deformation or damage caused by over-high pressure on to-be-welded positions and reduce the scrap rate of the workpieces; the pressure welding position is accurate and the welding quality and efficiency are improved.

Description

technical field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a pressure welding system. Background technique

[0002] In the existing production process of circuit boards, when soldering pads and leads in the circuit boards, manual soldering is usually used, and the soldering efficiency is low and the soldering effect is not satisfactory. In order to ensure the accurate and firm welding of the two, various types of welding equipment have appeared in the prior art to weld the pads and leads in the circuit board. The effect and efficiency of welding have been significantly improved, and the pressure welding effect is the best. , The welding speed is fast and the welding position is accurate. However, in the process of use, it was found that since the pressure welding uses the welding head for stamping welding, and the thickness of the circuit board is small, it is easy to deform and break when the welding point is unde...
