Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a full-automatic PCB board processing device. Background Art

[0002] PCBs are a key electronic component widely used in electronic devices. Made primarily of insulating material, they have conductive traces formed from copper foil on their surface. These traces are precisely arranged on the board through etching and printing techniques, forming the "roads" connecting electronic components. The primary function of a PCB is to enable electrical connections and signal transmission between electronic components, while also providing mechanical support and heat conduction.

[0003] In the prior art, during the PCB board processing, when soldering electrical components to the PCB board, the existing small soldering device has a low degree of automation. Generally, the user is required to manually place the PCB board on the workbench to fix it, then hold the soldering gun to perform soldering, and finally manually unload the board. This process not only increases the user's labor intensity, but also has low work efficiency. For this reason, a fully automatic PCB board processing device has been designed. Utility Model Content
