[0029] See also Figure 1-Figure 5The utility model provides a technical solution: a solder paste brushing tool that is easy to clean, including a tool base 1, a tool cover 2 is hinged on the surface of the tool base 1, a tin planting groove 20 is opened on the surface of the tool cover 2, an electronic component 5 is detachably installed on the surface of the tool base 1, a tool support plate 3 is fixedly connected to the surface of the tool base 1, a scraper 4 is detachably installed on the inner wall of the tin planting groove 20, a film 6 is detachably installed on the inner wall of the tin planting groove 20, a film 8 is glued to the surface of the film 6, and the film 8 is glued to the tin planting groove 20. When the electronic component 5 is tinned, the film 6 is then placed in the tin planting groove 20, the film 8 on the film 6 is completely bonded to the tin planting groove 20, and the film 6 is attached to the tin planting groove 20, and then the staff puts the tool cover 2 along the The tooling base 1 rotates and leans against the tooling backing plate 3. The staff places the electronic component 5 on the tooling base 1, then rotates the tooling cover 2 on the tooling base 1 to press on the electronic component 5, squeezes the solder paste into the tin planting tank 20, and the staff uses the scraper 4 to scrape the solder paste in the tin planting tank 20 flat. After multiple tin plantings, the staff tears off the film 6 so that no solder paste remains in the tin planting tank 20. The surface of the film 6 is fixedly connected with a pinching piece 11. The staff tears off the film 6 by pinching the pinching piece 11, which makes it convenient for the staff to tear off the film 6. The surface of the tooling cover 2 is detachably installed with a fixing block 7. The inner wall of the fixing block 7 is threadedly connected with a screw 17. The screw 17 is threadedly connected to the tooling cover 2. The inner wall of the fixing block 7 is threadedly connected with a screw 15. The screw One end of 15 is rotatably connected with a pressure plate 14, and the screw rod 17 is rotated to rotate the screw rod 17 in the fixed block 7 into the tooling cover plate 2. The staff installs the fixed block 7 on the tooling cover plate 2, and rotates the screw rod 15 to drive the pressure plate 14 to move. The pressure plate 14 will press the film 6 in the tin planting tank 20, which is convenient for the staff to stick the film 6 in the tin planting tank 20, and the screw rod 17 is rotated to remove the fixed block 7. The other end of the screw 15 is fixedly connected with a first handle 18, and one end of the screw rod 17 is fixedly connected with a second handle 19. The first handle 18 and the second handle 19 facilitate the staff to rotate the screw 15 and the screw rod 17 to rotate. The surface of the pressure plate 14 is fixedly connected with a round rod 16, and the round rod 16 is slidably connected to the fixed block 7. When the screw 15 drives the pressure plate 14 to move, the round rod 16 is slidably connected to the fixed block 7. The rod 16 will limit the moving path of the pressure plate 14, so that when the screw 15 drives the pressure plate 14 to move, the pressure plate 14 will not rotate with the screw 15, so that the pressure plate 14 moves smoothly. The surface of the film 8 is glued with a first baffle 9, and the surface of the film 8 is glued with a second baffle 10. The first baffle 9 and the second baffle 10 allow the staff to fix the film 6 before pasting the film when pasting it in the tin planting tank 20, so that the staff can correct the skewness when pasting the film, thereby improving the fault tolerance rate when pasting the film. The surface of the tooling cover 2 is fixedly connected with a magnetic piece 13, and the surface of the tooling support plate 3 is fixedly connected with a magnet 12.

[0030] Working principle: When the electronic component 5 is tinned, the screw 17 is rotated to rotate the screw 17 in the fixing block 7 into the tooling cover 2. The worker installs the fixing block 7 on the tooling cover 2, and then places the film 6 in the tin-planting tank 20. The screw 15 is rotated to drive the pressure plate 14 to move. The first handle 18 and the second handle 19 facilitate the worker to rotate the screw 15 and the screw 17. When the screw 15 drives the pressure plate 14 to move, the round rod 16 will limit the moving path of the pressure plate 14, so that the pressure plate 14 will not move with the screw 15 when the screw 15 drives the pressure plate 14 to move. 15 is rotated to make the pressure plate 14 move smoothly. The pressure plate 14 will press the film 6 in the tin planting tank 20, making it convenient for the staff to stick the film 6 in the tin planting tank 20. Then, the first baffle 9 is torn off, and the film 8 on the film 6 will be bonded to the tin planting tank 20. The screw rod 17 is rotated to remove the fixing block 7, and the second baffle 10 is torn off, so that the film 8 on the film 6 is completely bonded to the tin planting tank 20. The first baffle 9 and the second baffle 10 enable the staff to fix the film 6 before sticking it in the tin planting tank 20, so that the staff can fix the film 6 first when sticking it in the tin planting tank 20, so that when the film is skewed during sticking, In order to correct and improve the fault tolerance rate during film pasting, the film 6 is pasted in the tin planting tank 20, and then the staff rotates the tooling cover plate 2 along the tooling base 1 and leans against the tooling support plate 3. The magnetic sheet 13 on the tooling cover plate 2 will be adsorbed on the magnet 12 on the tooling support plate 3 to limit the tooling cover plate 2 to prevent the tooling cover plate 2 from tipping over when the staff places the electronic component 5. The staff places the electronic component 5 on the tooling base 1, and then rotates the tooling cover plate 2 on the tooling base 1 to press on the electronic component 5 to squeeze the solder paste into the tin planting tank 20. The staff uses the scraper 4 to remove the solder paste in the tin planting tank 20. The solder paste is scraped flat. After multiple tinning operations, the staff tears off the film 6. The staff tears off the film 6 by pinching the pinching piece 11, which is convenient for the staff to tear off the film 6, so that no solder paste will remain in the tinning tank 20. By setting the film 6 and the film 8, when tinning the electronic component 5, the staff sticks the film 6 in the tinning tank 20 on the tooling cover 2, and then tinns the electronic component 5. Excess solder paste will remain on the film 6. After the tinning operation, the film 6 in the tinning tank 20 is torn off, so that the staff does not need to clean the residual solder paste.
