Description

Technical Field

[0001] The utility model relates to the technical field of automatic soldering, in particular to an automatic soldering paste dispensing device with a positioning structure. Background Art

[0002] Soldering refers to a welding method that uses the high temperature of an electric soldering iron to melt a tin-based alloy and then fill the gap. Traditional soldering rods are often filled with a certain amount of rosin, which will produce gases harmful to the human body after high-temperature melting. In addition, manual soldering requires operators to undergo certain operational training before they can take up their posts, so existing soldering is mainly completed through automatic spot welding devices.

[0003] After searching, the patent document with authorization announcement number CN218517875U discloses an automated solder paste dispensing device with a positioning structure, including a mounting base, an electric lead screw is connected through the front side wall of the mounting base, a solder dispenser is fixedly installed at the middle position of the upper side wall on the movable end of the electric lead screw, and a side wall mounting plate is fixedly installed at the upper outer side of one side wall of the mounting base.

[0004] The above equipment also has the following shortcomings: when spot welding the welding points, due to the limited length of the placement module and the positioning module, the device needs to be opened for timely replacement after a certain amount of spot welding work, and the device is equipped with multiple sensors such as infrared sensors. When the welding rod is melted and spot welded, the high temperature and the smoke generated during spot welding will affect the infrared sensor, so it is easy to cause the overall spot welding of the device to be inaccurate and the device cannot operate normally.
