[0036] Working principle: When the device is used, the operator fixes different processing tables 6 to the moving plate 5 according to circuit boards of different specifications. By setting a positioning column 7 on the processing table 6, the operator can position the circuit board on the processing table 6 through the positioning column 7, and then place the tin on the discharge roller 141.

The connecting block 84 connected thereto can drive the metal cover 91 to move synchronously, so that the welding pen 112 can move laterally when in use, thereby improving the use effect.

[0039] By arranging an arc-shaped bracket 101 on the bracket 93, and a support plate 111 is arranged on the arc-shaped bracket 101, and the support plate 111 is connected to the welding pen 112, the support plate 111 can be rotated through the arc-shaped bracket 101, and the fixing block 103 is manually rotated in the opposite direction to form a gap between the fixing block 103 and the arc-shaped bracket 101. At this time, by means of the arc groove 104 arranged in the arc-shaped bracket 101, the arc-shaped bracket 101 is moved outside the threaded rod 102 through the arc groove 104, and the angle can be adjusted. When the angle is determined, the fixing block 103 is rotated forwardly to make the fixing block 103 and the arc-shaped bracket 101 in close contact, thereby changing the inclination angle of the welding pen 112 on the support plate 111, thereby improving the use effect and practicality of the welding equipment.
