The conveying port 2 is connected to one side of the body 1, and the conveying port 2 is connected to a packaging machine 3, and the conveying port 2 conveys the packaging plate 13 to the top of the packaging machine 3. The top of the packaging machine 3 is connected to a loading bucket 4, and the preformed solder sheets are poured into the loading bucket 4, and the preformed solder sheets then fall into the top of the shaking device 5 through the loading bucket 4.

[0022] like Figures 1 to 4As shown, the lower part of the loading bucket 4 is connected with a shaking device 5 for driving the packaging plate 13 to shake, and the shaking device 5 includes: a motor 51, a fixed frame 52, a rotating shaft 53, a rotating wheel 54, a belt 59, a rotating circle 55, a convex block 57, a protrusion 56 and a spring 58. The upper part of the packaging machine 3 is provided with a slide groove 6, one end of the motor 51 is horizontally located in the slide groove 6 and is slidably connected to the slide groove 6, and the motor 51 can only move vertically through the sliding groove. A moving groove 15 is provided inside the slide groove 6, and sliding blocks 16 are connected on both sides of the motor 51. The sliding blocks 16 are slidably connected to the moving groove 15, and the moving groove 15 prevents the motor 51 from falling. The output shaft of the motor 51 is fixedly connected to the rotating shaft 53, and the rotating shaft 53 is driven to rotate through the motor 51. The rotating shaft 53 passes through the fixed frame 52 and is rotatably connected to the fixed frame 52. The other end of the rotating shaft 53 is fixedly connected to the rotating circle 55, and the rotating shaft 53 drives the rotating circle 55 to rotate. The protrusion 56 is located outside the rotating circle 55 and is fixedly connected to the rotating circle 55, and the rotating circle 55 drives the protrusion 56 to rotate. The protrusion 57 is fixedly connected to the upper part of the packaging machine 3, and the protrusion 57 is arranged corresponding to the protrusion 56, and the protrusion 56 contacts the protrusion 57. There are multiple rotating shafts 53 and they are evenly arranged in the fixed frame 52 and are rotatably connected to the fixed frame 52. The multiple rotating shafts 53 are connected to the rotating wheel 54 on the side close to the rotating circle 55. The multiple rotating wheels 54 are connected by a belt 59, and the belt 59 drives the multiple rotating wheels 54 to rotate at the same time. The spring 58 is located between the fixed frame 52 and the packaging machine 3. An outlet 7 is opened on one side of the packaging machine 3. A fence 8 is connected to the side of the packaging machine 3 close to the outlet 7. The fence 8 is used to scrape the excess preformed solder sheets on the upper part of the packaging plate 13 into the loading box 14. The fixed frame 52 is rotatably connected to a rotating rod 11 inside, and the rotating rod 11 is connected to a plurality of rollers 12, which roll on the upper part of the packaging plate 13 to prevent the fence 8 from scraping the packaging plate 13. The fixed frame 52 is connected to a plurality of sliders 9 on both sides, and the packaging machine 3 is connected to a plurality of slide bars 10 on both sides. The sliders 9 pass through the slide bars 10 and are slidably connected to the slide bars 10, and the fixed frame 52 can only move vertically by sliding the sliders 9 on the slide bars 10. The packaging machine 3 is connected to a loading box 14 at the bottom, and the loading box 14 is used to store excess preformed solder sheets. A handle 17 is connected to one side of the loading box 14.

[0023] The working process of the above scheme is as follows: the machine body 1 conveys the packaging plate 13 to the conveying port 2, and then the conveying port 2 conveys the packaging plate 13 to the top of the rotating shaft 53. The motor 51 rotates to drive the rotating shaft 53 to rotate, and the rotating shaft 53 drives the rotating wheel 54 to rotate. The rotating wheel 54 rotates the belt 59, and the belt 59 causes multiple rotating wheels 54 and the rotating shaft 53 to rotate in one direction at the same time. The rotating shaft 53 drives the packaging plate 13 to move below the loading bucket 4. When the rotating shaft 53 rotates, it drives the rotating ring 55 to rotate. At this time, the protrusion 56 rotates and contacts the convex block 57. The protrusion 56 is forced to drive the rotating ring 55 and the rotating shaft 53 and other components to move up at the same time. The spring 58 is stretched by force, and the slider 9 slides on the slide bar 10. When the rotating shaft 53 shakes, it drives the packaging plate 13 to shake, and the packaging plate 13 shakes the preformed solder sheet into the groove. When the protrusion 56 no longer contacts the convex block 57, the spring 58 rebounds and drives the fixed frame 52 and other components to reset. The rotating shaft 53 continues to rotate to drive the packaging plate 13 to move toward the outlet 7. At this time, the roller 12 rotates to press the upper part of the packaging plate 13. When the packaging plate 13 moves, the scraper scrapes the excess preformed solder sheets on the upper part of the packaging plate 13 into the loading box 14. At this time, the packaging plate 13 is driven to the outlet 7 by the rotating shaft 53.

[0024] The above scheme has the following beneficial effects: the packaging plate 13 is transported to the top of the shaking device 5 through the machine body 1, and the shaking device 5 is started at this time to shake the packaging plate 13, so that the preformed solder sheets poured into the bucket 4 can be evenly poured into the holes of the packaging plate 13; the motor 51 is used to drive multiple rotating shafts 53 to rotate simultaneously to transport the preformed solder sheets, and at the same time, the motor 51 drives the rotating circle 55 to rotate so that the protrusion 56 contacts the protrusion 57, so that the spring 58 is compressed to drive the fixed frame 52 to rebound, and the fixed frame 52 causes the motor 51 and the rotating shaft 53 and other components to shake at the same time; the slider 9 slides on the slide bar 10 so that the fixed frame 52 can only slide vertically up and down; the guardrail 8 is used to scrape off the excess preformed solder sheets; the packaging plate 13 is pressed and rolled by the roller 12 to prevent the packaging plate 13 from moving when the guardrail 8 scrapes the preformed solder sheets.
