Description

technical field [0001] The invention relates 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 of manual soldering due to human factors. The soldering machine is mainly used for tinning on PCB boards with electronic components inserted Let the liquid tin stick to the insertion hole of the PCB board on the tin surface of the tin furnace, so that the electronic components can be soldered to the PCB board. Soldering machines mainly include immersion welding machines and wave soldering machines: 1. Immersion welding machines, which are about to fix the container for storing tin liquid, let the circuit board move downward, so that the welding surface reaches below the surface of the tin liquid, so as to achieve soldering the goal of. The disadvantage of this is that if the circuit board is moved up and down, it is prone to short circ...

Problems solved by technology

The control of the gimbal arm with this structure is not precise and stable enough

The soldering iron head of the automatic soldering robot disclosed in Japanese patent document JP 3226370 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. The soldering iron head with this structure cannot deflect the angle and is still not flexible enough

At the same time, there is an obvious defect in the above two kinds of soldering equipment: when the soldering iron head moves to the soldering working position for soldering, it will rise to move to the next soldering working position, so when performing a large number of soldering at the same horizontal working position , the soldering iron head still needs to be driven by the universal arm or the up and down movement mechanism, so that on the one hand, it is difficult to control the small travel distance accurately, on the other hand, the frequent movement of the universal arm or the up and down movement mechanism is easy to cause wear and affect the service life of the welding equipment

[0004] 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 relationship between the soldering position, the soldering iron tip is often required to perform soldering from different angles. However, the soldering operation often fails because the tin wire cannot be accurately delivered to the tin eating point of the soldering iron tip. In the later stage, manual repair work is still required, which wastes manpower and material resources. Therefore, most of the current automatic soldering machines are not suitable for industrial automation batches. Production requirements, therefore, how to accurately position the tin wire to the tin eating point of the soldering iron tip has become a problem that needs to be solved

[0005] At the same time, similar machines at home and abroad are large in size, high in the center of gravity, obviously insufficient in stability and rigidity, and there is a phenomenon of frame vibration during movement
