An automatic soldering robot

Abstract

The invention discloses an automatic tin soldering robot which comprises a soldering assembly and a tin wire locating mechanism. The soldering assembly comprises a first drive piece, a soldering piece and a first connecting piece. The tin wire locating mechanism comprises a tin wire guide pipe, a second connecting piece and a third connecting piece. The soldering piece is connected with the first drive piece through the first connecting piece. The second connecting piece is arranged on the soldering piece. The third connecting piece is arranged on the second connecting piece in a sliding manner in the height direction of the soldering piece. The tin wire guide pipe is rotationally arranged on the third connecting piece. According to the automatic tin soldering robot, transformation at any angle can be achieved, and the situation that the soldering piece impacts on a workpiece to be welded at a high speed, and consequently the workpiece is damaged can be avoided; and meanwhile, tin wires can be precisely located at soldering piece head soldering points on the soldering piece, and the soldering quality is improved.

Description

technical field [0001] The invention relates to the technical field of soldering, in particular to an automatic soldering robot. Background technique [0002] Automatic soldering technology has attracted more and more attention because it can solve the low-quality and low-efficiency problems caused by human factors in manual soldering. The soldering machine is mainly used for tinning on the PCB board with electronic components inserted, that is, to solder the electronic components on the PCB board. There are many kinds of soldering machines: immersion soldering machines, wave soldering machines, Cartesian coordinate system soldering machines, etc. The immersion soldering machine is to fix the container for storing tin liquid, and let the circuit board move downward, so that the welding surface reaches below the surface of the tin liquid, so as to achieve the purpose of soldering. The disadvantage of this operation is that the circuit board moves up and down, which is prone...

AI Technical Summary

Problems solved by technology

The disadvantage of this operation is that the circuit board moves up and down, which is prone to short circuit and soldering is not full, and the area of ​​the soldering surface of the circuit board does not match the upper surface area of ​​the container storing the tin liquid, and it is easy to waste tin liquid

The wave soldering machine moves the circuit board horizontally, and the bottom surface touches the tin liquid to complete the welding process, so it is difficult to guarantee the quality of welding

Dip soldering machines and wave soldering machines have great limitations, they can only move horizontally or up and down, and cannot achieve welding with welding angle requirements and high precision requirements

Cartesian coordinate system soldering machine, the soldering iron head of this soldering machine is controlled by the up and down direction movement mechanism and the left and right direction movement mechanism, it can only handle some simple solder joints, and the angle of the soldering iron head cannot be changed during the soldering process, which is inconvenient to use

For example, the soldering iron head of the automatic soldering robot disclosed in Japanese patent document JP3226370 is controlled by an up-down direction movement mechanism and a left-right direction movement mechanism, which can control the position of the soldering iron head more accurately, but the soldering iron head with this structure cannot deflect the angle and is still not flexible enough

[0003] In addition, the traditional automatic soldering machine often fails to achieve the expected effect due to inaccurate positioning during soldering. For example, when soldering large circuit boards or components, due to the position of the soldering tin, it is often necessary to use the soldering iron tip from different angles. Soldering operation, however, often fails because the tin wire cannot be accurately delivered to the tin eating point of the soldering iron tip, and the soldering operation still needs to be repaired manually in the later stage, which wastes manpower and material resources
