Description

Technical Field

[0001] This utility model relates to the field of scraper tools, specifically a multi-functional solder paste scraper that is easy to use. Background Technology

[0002] An easy-to-use, multi-functional solder paste squeegee is designed to meet the needs of solder paste application on printed circuit boards (PCBs) in electronic manufacturing processes, particularly in surface mount technology (SMT). This squeegee not only needs to be capable of efficiently and accurately dispensing solder paste, but also needs to be easy to operate and flexible enough to adapt to different working environments and requirements.

[0003] Current solder paste squeegees do not have replaceable brush heads; the entire squeegee must be replaced, which is inconvenient to use. Furthermore, the squeegee surface is easily contaminated during temporary storage, affecting the operator's use. Therefore, we have proposed a user-friendly, multi-functional solder paste squeegee. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a user-friendly multifunctional solder paste scraper, comprising a base, a placement box fixedly connected to one side of the base, a handle provided on one side of the placement box, a sleeve fixedly connected to one side of the handle, a scraper threadedly connected inside the sleeve, an insertion rod fixedly connected to one side of the handle, limit grooves formed on both sides of the insertion rod, a beveled insertion block fixedly connected to one side of the insertion rod, and a circular groove formed on one side of the placement box, with the interior of the circular groove movably connected to the insertion rod.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses a user-friendly multifunctional solder paste scraper, including a base 1, a placement box 2 fixedly connected to one side of the base 1, a handle 3 provided on one side of the placement box 2, a sleeve 4 fixedly connected to one side of the handle 3, a scraper 5 threadedly connected inside the sleeve 4, an insertion rod 6 fixedly connected to one side of the handle 3, limit grooves 7 provided on both sides of the insertion rod 6, a beveled insertion block 8 fixedly connected to one side of the insertion rod 6, and a circular groove 9 provided on one side of the placement box 2, with the interior of the circular groove 9 movably connected to the insertion rod 6.

[0025] The placement box 2 has an internal movable groove 10. The movable groove 10 has two slidingly connected snap-fit ​​blocks 11 on its inner sides. The snap-fit ​​blocks 11 are movably connected to the limiting groove 7. The outer sides of the two snap-fit ​​blocks 11 are fixedly connected to a return spring 12. One end of the return spring 12 is fixedly connected to the inner wall of the movable groove 10. By setting the return spring 12, the snap-fit ​​blocks 11 are pushed into the circular groove 9 to limit the limiting groove 7.

[0026] The upper end of the snap-fit ​​block 11 is fixedly connected to the inclined block 13, the upper end of the movable groove 10 is slidably connected to the pressure plate 14, and the lower part of the pressure plate 14 is movably connected to the inclined block 13. The interior of the movable groove 10 is fixedly connected to the fixing block 15. By setting the inclined block 13, the pressure plate 14 presses down on the inclined block 13, causing the snap-fit ​​block 11 to move and squeeze the reset spring 12, thereby releasing the limitation on the limiting groove 7.

[0027] The upper end of the fixing block 15 is fixedly connected to a compression spring 16, and the upper end of the compression spring 16 is fixedly connected to the lower end of the pressure plate 14. The upper end of the pressure plate 14 is fixedly connected to a pressing post 17, and the outer periphery of the pressing post 17 is slidably connected to the placement box 2. By setting the compression spring 16, the pressure plate 14 is pushed to cancel the force on the inclined block 13, so that the locking block 11 continuously limits the limiting groove 7.

[0028] The placement box 2 has a storage slot 18 on one side and a through slot 19 on the upper end of one side. A brush 20 is installed inside the through slot 19. By placing the upper end of the scraper 5 into the through slot 19 and sliding the scraper 5, the solder paste on the surface of the scraper 5 is wiped off, and the surface of the scraper 5 is cleaned.

[0029] The storage slot 18 is movably connected to the storage box 21. A scraper 22 is fixedly connected to one side of the storage box 21, and a door 23 is rotatably connected to one side of the placement box 2. After the scraper 5 slides and cleans the inside of the channel 19 by the scraper 22, some solder paste remains at the lower end of the channel 19. It is scraped off by the scraper 22. At the same time, the scraped solder paste can flow into the storage box 21 for collection and recycling.

[0030] The upper surface of the base 1 is movably connected to a movable box 24, and a storage box 25 is slidably connected to one side of the base 1. By setting the movable box 24, it is placed under the used scraper 5, which avoids the scraper 5 from contacting the surface of the base 1 and causing blade contamination, thus enhancing the practicality of the device.

[0031] Working principle: In use, the handle 3 and scraper 5 are connected together by threads. After scraper 5 is used, the inclined block 8 is inserted into the circular groove 9. During the locking process, the inclined surface of the inclined block 8 moves into the circular groove 9 under the action of pushing force. When the inclined surface of the inclined block 8 contacts and pushes the inclined surface of the locking block 11, the locking block 11 is pressed against the return spring 12. When the locking block 11 moves to the end of the inclined block 8, the rebound force of the return spring 12 moves the locking block 11 into the limiting groove 7. When it is necessary to remove the handle 3, the pressing post 17 is pressed, which causes the inclined surface at the bottom of the pressure plate 14 to move the inclined block 13, and at the same time, it compresses the compression spring 16, causing the inclined block 13 to move the locking block 11. By squeezing the reset spring 12, the limiting groove 7 and the inclined insert 8 are removed, facilitating frequent disassembly. This completes the disassembly of the limiting groove 7 and the snap-fit ​​block 11. By placing the upper end of the scraper 5 into the through groove 19 and sliding the scraper 5, the solder paste on the surface of the scraper 5 is wiped away, cleaning the surface of the scraper 5. After the scraper 5 slides and cleans the inside of the through groove 19, some solder paste remains at the lower end of the through groove 19. This is then scraped off by the scraper 22. At the same time, the scraped solder paste flows along the scraper 22 into the collection box 21 for collection and recycling. The movable box 24 is placed below the used scraper 5 to prevent the scraper 5 from contacting the surface of the base 1 and causing blade contamination, thus enhancing the practicality of the device.
