A sliding hole 508 is provided on the upper surface of the pressure plate 502, and a sliding rod 509 is slidably connected to the inner wall of the sliding hole 508. The lower end of the sliding rod 509 is fixedly connected to the feeding gun 1, and the upper end of the sliding rod 509 is fixedly connected to the baffle 510. The pressure plate 502 is fitted with the baffle 510 through the interrupter plate 504, and the baffle 510 has the effect of limiting the rotation angle of the pressure plate 502. The interrupter plate 504 is an acrylic plate, and the pressure plate 502 is an acrylic plate. With the help of the pressure plate 502 which is an acrylic plate, the situation of the feeding port 4 can be better observed.

[0032] like Figure 3 and Figure 4As shown, the supporting structure 6 includes a threaded tube 61, the upper surface of the threaded tube 61 is fixedly connected to the feeding gun 1, the inner wall of the threaded tube 61 is threadedly connected with a screw 62, the arc surface of the screw 62 is slidably connected with a connecting frame 63, and the lower surface of the connecting frame 63 is fixedly connected with two support plates 64, and the end of the screw 62 away from the threaded tube 61 is fixedly connected with a turning handle 65, and the arc surface of the turning handle 65 is provided with a plurality of inner grooves, and the turning handle 65 is rotated to drive the screw 62 to rotate, and the turning handle 65 plays a role in better rotating the screw 62, and the arc surface of the feeding gun 1 relative to the two sides of the connecting frame 63 is fixedly connected with side plates 66, and the sides of the two side plates 66 close to each other are slidably connected to the connecting frame 63, and the connecting frame 63 slides in the two side plates 66, and the side plates 66 play a role in limiting the supporting position of the connecting frame 63.

[0033] Working principle: When it is necessary to feed and solder electronic components with solder paste, first input the solder paste into the feeding gun 1 through the material tube 2, then drive the feeding port 4 to move to the feeding position above the component, and then press the button 3. The feeding gun 1 starts the button 3 to allow the internal solder paste to flow out through the feeding port 4 and then flow onto the component. After the solder paste is fed to the component to a certain extent, release the button 3 and press the pressing plate 502 again. The pressing plate 502 squeezes the cut-off plate 504 through the rotating frame 501. The sliding hole 508 on the upper surface of the pressing plate 502 slides on the arc surface of the sliding rod 509 and separates from the baffle 510. The cut-off plate 504 rotates and slides from one side of the feeding port 4 through the pressing plate 502 with the help of the long rod 503, so that the solder paste adhering to the surface of the feeding port 4 is scraped off. , so that the adhered tin solder paste drips completely on the components, and the fixed plate 505 squeezes the spring 506 through the rotation of the cut-off plate 504.

[0034] When it is necessary to place the loading gun 1, first use the turning handle 65 to drive the screw 62 to rotate to the side away from the threaded tube 61. After the screw 62 is separated from the inner wall of the threaded tube 61, the connecting frame 63 is rotated to one hundred and eighty degrees on the arc surface of the screw 62, and then the screw 62 is rotated again with the turning handle 65. The screw 62 is inserted into the threaded tube 61 and rotates and moves, and the turning handle 65 drives the connecting frame 63 to slide between the two side plates 66. The side plates 66 play the role of limiting the supporting position of the connecting frame 63. Until the connecting frame 63 is in contact with the threaded tube 61, the turning handle 65 is released. The turning handle 65 plays the role of better rotating the screw 62, and then the loading gun 1 is placed horizontally, and the threaded tube 61 drives the support plate 64 of the connecting frame 63 to fit with the table surface through the loading gun 1 with the help of the screw 62, so that the loading gun 1 and the interrupter plate 504 are supported at a high place.
