Each tilting assembly is located in each tilting cavity 117 for rotating the substrate 101. The welding piece is fixed between the two first electric push rods 114 and the fourth electric push rods 116. If it is necessary to adjust the upper and lower positions of the welding piece, the two first electric push rods 114 and the fourth electric push rods 116 can be started. When rotating the fixed welding piece, the rotating motor 105 is started, the second gear 106 rotates, and under the action of the first gear 104, the mounting frame 107 is rotated through the rotating shaft 103 until the horizontal angle of the welding piece is adjusted.

At this time, the mounting frame 107 cannot rotate, which can effectively prevent shaking during welding and cause cold welding. If it is necessary to perform inclined welding on the fixed welding piece, the two The brake member adjusts the inclination of the substrate 101 through the two rotating shafts 109 and the two rotating blocks 108 until the desired inclination is reached, and the two double-threaded columns 110 are twisted, and the four fixing plates 112 are close to the mounting frames 107 on both sides of the rotating block 108 until the four fixing plates 112 are close to the inner wall of the tilting cavity 117.
