[0033] like Figure 3-Figure 5 As shown, the adsorption component 2 includes: adsorption holes 201, multiple adsorption holes 201 are opened in the containing shell 103; pipelines 202, the pipelines 202 are installed on the containing shell 103, and the adsorption holes 201 are connected to the pipelines 202; and an air source component 21, which is installed on the fixing plate 100.

[0034] like Figure 3-Figure 5 As shown, the air source assembly 21 includes: a compression chamber 211, which is opened in the fixed plate 100; a piston 212, which is slidably arranged in the compression chamber 211; a screw 213, which is threadedly connected to the fixed plate 100, and one end of the screw 213 is connected to the piston 212; a rotating cap 214, which is installed on the screw 213, and the pipeline 202 is connected to the compression chamber 211.

[0035] like Figure 6As shown, the limiting assembly 3 includes: a connecting rod 311, which is installed on the swing rod 102 and is rotatably arranged in the groove 1011; a fixing cylinder 312, which is installed on the connecting plate 101; a nut 313, which is threadedly connected to the outside of the fixing cylinder 312; and an extrusion block 314, which is installed in the nut 313.

[0036] Working principle: When welding, first put the PCB board 600 into the receiving groove 1001 to realize the positioning of the PCB board 600, put the electronic component 601 into the receiving shell 103, and use the adsorption component 2 to negatively adsorb the electronic component 601 in the receiving shell 103, and rotate the swing rod 102 downward to drive the electronic component 601 in the receiving shell 103 to move onto the PCB board 600.

[0037] Regarding the function of the adsorption assembly 2: the rotating cap 214 is rotated forward to drive the screw 213 to rotate.
