Technical Field

[0001] The utility model relates to the technical field of multi-head soldering, in particular to a multi-head automatic soldering machine. Background Art

[0002] A multi-head soldering machine is an automated device primarily used in mass production and electronic assembly. It can perform soldering on multiple joints simultaneously, significantly improving production efficiency. Equipped with multiple solder guns or iron tips, this machine can perform soldering operations on multiple electronic components simultaneously, making it suitable for large-scale production lines.

[0003] When performing welding, traditional multi-head soldering machines do not fix the workpiece stably enough, which can easily cause the workpiece to shift during the welding process. If the workpiece shifts, it will cause damage to multiple items being welded at the same time, causing huge losses and a low welding success rate.

[0004] Therefore, those skilled in the art provide a multi-head automatic soldering machine to solve the problems raised in the above background technology. Utility Model Content

Before welding, the device can press down and fix the workpiece to be welded through two sets of downward pressing and fixing plates, which can avoid the workpiece from deflecting and damaging the workpiece caused by deflection. In addition, the downward pressing and fixing plates can be quickly pulled apart to press down and fix the workpiece through the contraction spring, and the installation and removal of the workpiece are very convenient and fast.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] Furthermore, first electric slide rails are fixedly provided on both sides of the welding table, first electric sliders are slidably provided on the two first electric slide rails, and support plates are fixedly provided on the tops of the two first electric sliders;
