[0020] A preferred embodiment of the rolling and stirring device for semiconductor silver paste provided by the present invention is as follows Figures 1 to 8As shown in the figure: A vibration component 33 is arranged on the side of the rolling component 32. The vibration component 33 includes a driving wheel 331 fixedly connected to the outer wall of the other end of the driving shaft 323. The outer wall of the driving wheel 331 is connected to a driven wheel 332 through belt transmission. The inner wall of the driven wheel 332 is fixedly connected to a transmission shaft 333.

The outer wall of the limiting horizontal plate 3310 is slidably connected to a limiting frame 3311. The bottom of the limiting frame 3311 is fixedly connected to the top of the L-shaped side plate 334. By setting the vibration component 33, when the driving shaft 323 rotates, it will cause the driving wheel 331 to rotate.

During the rotation of the transmission shaft 333, it will cause the extrusion roller 335 to rotate. During the rotation of the extrusion roller 335, the fixed column 337 will be extruded inside the extrusion groove 336 on its outer wall. Under the action of limiting the displacement block 338 by the limiting frame 3311 and the limiting horizontal plate 3310, the fixed column 337 can move reciprocally, driving the striking hammer 339 to move reciprocally. During the reciprocal movement of the striking hammer 339, it will strike the back of the mixing barrel 2, facilitating the striking and falling of the semiconductor silver paste adhering to the inner wall of the mixing barrel 2 during the mixing process.

[0021] Furthermore, an L-shaped support block 4 is fixedly connected to the top of the bottom plate 1.

[0025] Working principle: when the semiconductor silver glue in the mixing barrel 2 needs to be stirred, the operator turns on the first driving motor 311 to cause the output shaft 312 to rotate. During the rotation of the output shaft 312, the stirring frame 314 is caused to rotate, so that the semiconductor silver glue in the mixing barrel 2 is stirred and mixed through the stirring frame 314. During the rotation of the stirring frame 314, the scraper 317 is caused to rotate. The semiconductor silver glue attached to the inner wall of the mixing barrel 2 during the stirring process can be scraped off through the rotation of the scraper 317. When the stirring frame 314 rotates, the paddle plate 316 inside it will rotate with the rotation of the stirring frame 314 under the action of gravity and its own gravity, so as to paddle the semiconductor silver glue in the mixing barrel 2, thereby improving the stirring and mixing effect of the semiconductor silver glue in the mixing barrel 2; By setting the feed port 3110 and the discharge port 318, when the semiconductor silver paste needs to be stirred, the operator opens the first solenoid valve 3111, and then puts the semiconductor silver paste that needs to be stirred and mixed into the stirring barrel 2 through the feed port 3110. After the semiconductor silver paste is stirred and mixed, the operator opens the second solenoid valve 319 to cause the semiconductor silver paste that has been stirred and mixed to be discharged through the discharge port 318. When the semiconductor silver paste is being stirred and mixed inside the stirring barrel 2, in order to improve the mixing effect of the stirring barrel 2 on the semiconductor silver paste, the stirring barrel 2 can be rotated to rotate and reverse with the stirring frame 314 inside it, thereby improving the mixing effect of the semiconductor silver paste. At this time, the operator turns on the second driving motor 322 to cause the driving shaft 323 to rotate. During the rotation of the driving shaft 323, the gear 324 is caused to rotate. During the rotation of the gear 324, the gear 324 is meshed with the gear ring 325, causing the gear ring 325 to rotate. During the rotation of the gear ring 325, the stirring barrel 2 is limited by the limiting block 326 and the limiting ring 327, which causes the stirring barrel 2 to rotate, causing the limiting block 326 to rotate on the inner wall of the limiting ring 327, thereby achieving the purpose of rolling stirring of the semiconductor silver paste. When the driving shaft 323 rotates, it will cause the driving wheel 331 to rotate. During the rotation of the driving wheel 331, it will drive the driven wheel 332 to rotate through belt transmission, thereby driving the transmission shaft 333 to rotate. During the rotation of the transmission shaft 333, it will cause the extrusion roller 335 to rotate. During the rotation of the extrusion roller 335, the inside of the extrusion groove 336 on its outer wall will extrude the fixed column 337. Under the action of limiting the displacement block 338 by the limiting frame 3311 and the limiting cross plate 3310, the fixed column 337 can generate reciprocating movement, driving the striking hammer 339 to reciprocate. During the reciprocating movement of the striking hammer 339, it will strike the back of the mixing barrel 2, facilitating the striking and shaking off of the semiconductor silver glue adhering to the inner wall of the mixing barrel 2 during the mixing process.
