Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing technology, and in particular to a jig for scraping off residual adhesive from rectifier pins. Background Technology

[0002] like Figure 3 This is a three-dimensional structural diagram of a rectifier. The rectifier includes a package 1, with a chamfered corner 11 at one corner, four pins 12 at the front end, and a central hole 10. After injection molding, some products of this rectifier's package 1 may have residual adhesive at the base of the pins 12. The presence of this residual adhesive can affect product quality and application in certain scenarios. Since a small amount of this residue is generated during the injection molding process, operators currently often scrape it off with a utility knife. This method is inefficient and has the problem of some residual adhesive being difficult to remove. Utility Model Content

[0003] This utility model provides a fixture for scraping off residual adhesive from rectifier pins, which solves the shortcomings of the prior art and addresses the problem of inconvenient removal of residual adhesive from pins, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A fixture for scraping residual adhesive from rectifier pins includes a fixing part and a scraping part. The fixing part is used for constraining and positioning the rectifier package, and the scraping part is used for scraping residual adhesive from the root of the rectifier pins.

[0005] Furthermore, the fixing part includes a fixing plate, on which a constraint groove is formed with an opening on the upper wall. The front end of the constraint groove is open, the pins of the rectifier extend out of the front end of the constraint groove, and the package of the rectifier is placed in the constraint groove.

[0006] Furthermore, the upper wall of the fixing plate is connected to a connecting screw by a thread, the upper end of the connecting screw is provided with an end cap, a pressure plate is movably provided on the connecting screw, the other end of the pressure plate is provided with a lower insertion rod extending downward, a spring is sleeved on the connecting screw, the upper end of the spring abuts against the lower end of the end cap, the lower end of the spring abuts against the upper wall of the pressure plate, and the lower insertion rod is inserted into the central hole of the encapsulation body.

[0007] Furthermore, a gripping hole is provided at the rear end of the fixing plate.

[0008] Furthermore, there is a notch at one corner of the fixing plate.

[0009] Furthermore, the scraping section includes a pair of guide rods connected to the front end of the fixed plate by threads. The outer ends of the guide rods are formed with heads. Movable blocks are movably mounted on the guide rods. The upper and lower ends of the movable blocks are respectively connected to guide rods by threads. The other end of the guide rods is provided with a constraint cap. Long strips are provided on the upper and lower sides of the movable blocks. The guide rods pass through the long strips. Multiple inner plates are fixed to the inner side of the long strips by multiple screws. The inner end of the inner plate is bent with a scraper. The scraper has a concave structure and the inner side of the scraper has a blade-shaped structure. The scrapers are in a one-to-one correspondence relationship, and each pair of scrapers is sleeved on the pin.

[0010] Furthermore, a V-shaped spring piece is fixed to the inner end of the movable block by a pin, and the other end of the spring piece abuts against the inner wall of the long strip.

[0011] The advantages of the above technical solution are: This invention uses a constraint groove to constrain the package, allowing for precise scraping of residual adhesive from each pin using a scraper. Furthermore, a lower insert rod positions the package, preventing movement during the scraping process and ensuring effective removal.

[0012] This invention uses a fully enclosed scraper to remove residual adhesive, thereby improving the scraping effect and reducing the difficulty of scraping. Attached Figure Description

[0017] like Figures 1-3 As shown, a fixture for scraping residual adhesive from rectifier pins includes a fixing part and a scraping part. The fixing part is used for constraining and positioning the rectifier package 1, and the scraping part is used for scraping residual adhesive from the roots of the rectifier pins 12.

[0018] The fixing part includes a fixing plate 2. A constraint groove 200 is formed on the upper wall of the fixing plate 2. The front end of the constraint groove 200 is open, and the pins 12 of the rectifier extend from the front end of the constraint groove 200. The rectifier's package 1 is placed inside the constraint groove 200. A connecting screw 33 is threadedly connected to the upper wall of the fixing plate 2. An end cap 34 is provided at the upper end of the connecting screw 33. A pressure plate 36 is movably mounted on the connecting screw 33. A lower insertion rod 37 extends downward from the other end of the pressure plate 36. A spring 35 is sleeved on the connecting screw 33. The upper end of the spring 35 abuts against the lower end of the end cap 34, and the lower end of the spring 35 abuts against the upper wall of the pressure plate 36. The lower insertion rod 37 is inserted into the central hole 10 of the package 1. A holding hole 20 is provided at the rear end of the fixing plate 2. A notch 21 is provided at one corner of the fixing plate 2.

[0019] The scraping section includes a pair of guide rods 22 connected to the front end of the fixed plate 2 by threads. The outer end of the guide rod 22 is formed with an end head 23. The guide rod 22 is movably provided with a movable block 24. The upper and lower ends of the movable block 24 are respectively connected with guide rods 25 by threads. The other end of the guide rod 25 is provided with a constraint cap 26. The upper and lower sides of the movable block 24 are respectively provided with long strips 27. The guide rods 25 pass through the long strips 27. The inner side of the long strips 27 is fixed with multiple inner plates 31 by multiple screws. The inner end of the inner plate 31 is bent with a scraper 32. The scraper 32 has a concave structure and the inner side of the scraper 32 has a blade-shaped structure. The scrapers 32 are in a one-to-one correspondence relationship, and each pair of scrapers 32 is sleeved on the pin 12. The inner end of the movable block 24 is fixed with a V-shaped spring piece 28 by a pin. The other end of the spring piece 28 abuts against the inner wall of the long strip 27.

[0020] In this embodiment, during operation, the operator places the package 1 into the constraint groove 200, with the pin 12 positioned at the front end of the constraint groove 200.

[0021] Then, the pressure plate 36 is rotated, and during the rotation, the pressure plate 36 is pulled upward, so that the lower insertion rod 37 is aligned with the central hole 10. Then, the upward pulling force on the pressure plate 36 is released, and the pressure plate 36 will be inserted into the central hole 10 under the action of the spring 35.

[0022] Next, move the long strip 27 backward so that the scraper 32 is located at the root of the pin 12. Then, press the scraper 32 inward and make it fit over the root of the pin 12. During the fitting process, some residual adhesive will be cut off by its blade. Then, move it while pressing the long strip 27 to completely remove the residual adhesive at the root of the pin 12.
