[0020] Working Principle: When using this invention, the welding head matrix 3 is used to weld the product.

External ventilation equipment then draws in the fumes generated during welding, accelerating airflow and facilitating cooling of the welding head matrix 3. The angle of the welding head matrix 3 can be adjusted by adjusting the support assembly 1 to suit different products. The adjustment method is as follows: the adjusting block 17 is connected to an external drive device capable of linear reciprocating motion. The drive device drives the adjusting block 17, which in turn drives the screw 16. The screw 16 deflects around the first pin 19, causing the first connecting seat 15, connecting block 18, and second connecting seat 110 on the screw 16 to move accordingly. The second connecting seat 110 is driven to swing via the second pin 111. One end of the arm 112 and the other end of the swing arm 112 deflect on the second fixed rod 116 via the first groove 114. The swing arm 112 drives the connecting frame 13 via the third pin 113. The connecting frame 13 deflects on the first fixed rod 12 via the second groove 115. The mounting frame 14 on the connecting frame 13 moves accordingly, and the welding head matrix 3 on the mounting frame 14 also moves accordingly. The fixing plate 11 is used to install the first fixed rod 12 and the second fixed rod 116. The welding head matrix 3 is composed of welding head units 31. The shape of the welding head matrix 3 can be a square matrix, an S-shaped matrix, a circular matrix, etc. The air extraction equipment uses a vacuum pump. The drive device for linear reciprocating motion can be a hydraulic, pneumatic, or electric drive device. The exhaust fan and the drive device for linear reciprocating motion are existing technologies and will not be described in detail here.
