[0029] Working principle:

[0030] After opening the lid of the solder paste can 8, the solder paste can 8 is placed inside the cylinder 7, and then the bolts 91 are tightened so that the solder paste can 8 is clamped and fixed inside the cylinder 7 by the two arc-shaped plates 92. Subsequently, the connecting block 21 and the horizontal plate 18 are driven downward by the second cylinder 22. During this period, the stirring mechanism moves downward together with the horizontal plate 18 until the stirrer 20 extends into the solder paste can 8. The stirrer 20 can be driven by the motor 19 to stir the solder paste inside the solder paste can 8. During this period, the reduction motor 12 can be started, and the reduction motor 12 drives the second pulley 13, the belt 14 and the first pulley 11 to drive the stirring mechanism. The shaft 10 and the cylinder 7 rotate, thereby causing the solder paste tank 8 to rotate, and at the same time, the first cylinder 17 repeatedly pushes and pulls back the side plate 15. When the side plate 15 moves back and forth, it drives the mounting seat 3 and all the components mounted on the mounting seat 3 to move back and forth synchronously. The mounting seat 3 slides along the slide rod 5 through the sliding sleeve 4. During this process, the solder paste tank 8 rotates and moves back and forth at the same time. When the stirrer 20 stirs the solder paste inside the solder paste tank 8, it can involve the center of the solder paste tank 8 and the area close to the inner wall, so that the solder paste inside the solder paste tank 8 is stirred more fully;

[0031] After the stirring is completed, the second cylinder 22 pushes the horizontal plate 18 and the stirring mechanism upward until the stirrer 20 moves up to the top of the solder paste can 8, and then the first cylinder 17 pushes the side plate 15 forward, that is, the mounting seat 3 and the solder paste can 8 on the mounting seat 3 are moved forward, and then the clamping mechanism 9 is released to fix the solder paste can 8, and then the solder paste can 8 can be extracted from the cylinder 7.
