The performance and functionality of chips are constantly being upgraded, while their specifications and models are becoming increasingly diverse. Disassembly and assembly of chips are frequently required during the production, repair, and research and development of electronic products.

[0003] However, some problems still arise in actual chip assembly and disassembly work. When disassembling chips in batches, a hot air gun is typically used to heat the chips, melting the solder and allowing it to detach, thus separating the chip from the circuit board. However, in practice, during batch disassembly, a small amount of molten solder may overflow. This overflowing solder poses a significant hazard. Firstly, it contaminates the working environment; secondly, it can easily flow onto surrounding electronic components or circuit boards, causing short circuits and other malfunctions. Once such malfunctions occur, the performance and quality of electronic products will be affected, repair costs will increase accordingly, and production risks will rise. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-5 The illustrated universal mounting and dismounting fixture suitable for various chip specifications includes a cuboid fixture body 2 and a rectangular slide 7 disposed inside the cuboid fixture body 2. The top of the rectangular slide 7 is open, and a partition block 14 is disposed inside the center of the rectangular slide 7. Fixture sliders A13 and B11 are respectively disposed inside the rectangular slide 7, located to the right and left of the partition block 14. A clamping plate fixing plate A4 is fixed to the top of the clamping slider A13 by an embedded screw. The left end of the clamping plate fixing plate A4 is... A chip clamping plate A5 is provided. A clamping plate fixing plate B10 is fixed to the top of the clamping slider B11 via an embedded screw. A chip clamping plate B6 is provided at the right end of the clamping plate fixing plate B10. Chip clamping plates A5 and B6 extend horizontally to the left and right, respectively. A disassembly and collection integrated device 12 is provided at the top of the partition block 14. This universal disassembly and collection clamp is applicable to various chip specifications. Its design aims to achieve stable clamping and convenient disassembly and collection of chips of different specifications. The clamp is based on a cuboid clamping body 2 and a rectangular slide groove 7 with an opening at the top. The partition block at the center of the slide groove... Block 14 places clamp sliders A13 and B11 on the left and right sides respectively. Clamp sliders A13 and B11 are fixed to clamping plate fixing plate A4 and clamping plate fixing plate B10 by embedded screws, thereby driving the horizontally extended chip clamping plate A5 and chip clamping plate B6 to clamp the chip. In terms of adjustment mechanism, clamp sliders A13 and B11 are provided with adjustment screw holes in the center, which cooperate with the through holes and fixing holes on the cuboid clamp body 2 and the middle partition block 14. Through the threaded engagement of clamp screws A3 and B9 with the adjustment screw holes, the adjustment knob A1 is rotated and the adjustment is adjusted. Knob B8 drives the clamp screw to rotate clockwise and counterclockwise, thereby enabling the clamp sliders A13 and B11 to move left and right within the slide groove. This allows for precise adjustment of the distance between chip clamps A5 and B6 to accommodate different chip sizes. To prevent axial displacement of the clamp screw, a fixed retaining ring is fitted at the corresponding position to block it against the inner wall of the slide groove and the outer wall of the clamp body, ensuring adjustment accuracy and structural stability. In addition, a soft rubber anti-slip pad is attached to the bottom of the cuboid clamp body 2 to increase friction with the worktable surface, preventing the clamp from sliding during operation and ensuring smooth chip assembly and disassembly.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, both the clamp slider A13 and clamp slider B11 have adjusting screw holes at their centers. The rectangular clamp body 2 has through holes at both ends. The partition block 14 has fixing holes at both ends. A clamp screw A3 is threaded into the adjusting screw hole inside the clamp slider A13. The left end of the clamp screw A3 is inserted into the fixing hole at the right end of the partition block 14. The right end of the clamp screw A3 passes through the through hole at the right end of the rectangular clamp body 2. The clamp screw A3 has an adjustment knob A1 on its right end. The clamp screw B9 is threaded into the adjustment screw hole inside the center of the clamp slider B11. The right end of the clamp screw B9 is inserted into the fixing hole inside the left end of the partition block 14. The left end of the clamp screw B9 passes through the through hole inside the left end of the cuboid clamp body 2. The left end of the clamp screw B9 has an adjustment knob B8. Both the clamp slider A13 and the clamp slider B11 can only slide left and right inside the rectangular slide groove 7. The adjustment knobs A1 and B8 can drive the clamping screws A3 and B9 to rotate clockwise and counterclockwise, respectively. The clockwise and counterclockwise rotation of clamping screw A3, through the adjusting screw hole, drives clamping slider A13 to move left and right within the rectangular groove 7. Similarly, the clockwise and counterclockwise rotation of clamping screw B9, through the adjusting screw hole, drives clamping slider B11 to move right and left within the rectangular groove 7. This design allows the clamping screws A3 and B9 to rotate clockwise and counterclockwise by rotating the adjustment knobs A1 and B8. Due to the threaded fit between the adjusting screw hole and the clamping screw, the rotation of clamping screw A3 drives clamping slider A13 to move left and right within the rectangular groove 7, and the rotation of clamping screw B9 drives clamping slider B11 to move left and right within the rectangular groove 7. This enables precise adjustment of the distance between chip clamping plates A5 and B6 to accommodate the size requirements of chips of different specifications.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, two limiting rings are respectively sleeved and fixed on the outer right side of the center of clamp screw A3 and the outer left side of the center of clamp screw B9. The two limiting rings fixed on the outer side of clamp screw A3 block the inner wall of the right end of rectangular slide groove 7 and the outer wall of the right end of cuboid clamp body 2, respectively. The two limiting rings fixed on the outer side of clamp screw B9 block the inner wall of the left end of rectangular slide groove 7 and the outer wall of the left end of cuboid clamp body 2, respectively. When clamp screw A3 and clamp screw B9 rotate clockwise and counterclockwise, the limiting rings can prevent clamp screw A3 and clamp screw B9 from displacing in the left and right directions, respectively. To prevent clamp screw A3 and clamp screw B9 from rotating during the rotation process... To prevent unnecessary axial displacement, two limiting rings are fixedly fitted to the outer right side of the center of clamp screw A3 and the outer left side of the center of clamp screw B9. These two limiting rings block the inner wall of the corresponding end of the rectangular slide groove 7 and the outer wall of the corresponding end of the cuboid clamp body 2, respectively. This ensures that the limiting rings can effectively prevent displacement in the left and right directions when the clamp screw rotates clockwise or counterclockwise, thus ensuring the stability of the clamp structure and the accuracy of adjustment. A soft rubber anti-slip pad is also attached to the outer wall of the bottom end of the cuboid clamp body 2. The soft rubber anti-slip pad can increase the friction with the worktable surface and prevent the clamp from sliding during operation, ensuring the smooth progress of chip assembly and disassembly.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, the integrated disassembly and collection device 12 includes a rectangular metal plate 15, a rectangular hollow groove 16, a perforated placement plate 17, a metal plate fixing piece 20, and fixing screws 21. In a universal disassembly and collection fixture suitable for various chip specifications, the integrated disassembly and collection device 12 plays a crucial role in chip placement, disassembly and collection operations, and waste or liquid collection. Its ingenious design and coordinated operation of all components enable an efficient and convenient chip disassembly and collection process. The basic structure of the device is built around the rectangular metal plate 15, which has a bottom center with front and rear sides... The metal plate fixing pieces 20 are horizontally and stably placed on the top of the partition block 14. The metal plate fixing pieces 20 are attached to the outer walls of the left and right ends of the partition block 14 and are tightly fixed to the partition block 14 by fixing screws 21, ensuring the overall stability and firmness of the device and enabling it to function reliably in the overall structure of the clamp. A set of metal plate fixing pieces 20 is provided on both the front and rear sides of the bottom center of the rectangular metal plate 15. The rectangular metal plate 15 is horizontally placed on the top of the partition block 14, and the two sets of metal plate fixing pieces 20 are respectively attached to the left and right ends of the partition block 14. On both outer walls, and with both sets of metal plate fixing pieces 20 fixedly connected to the middle partition block 14 by fixing screws 21, the rectangular metal plate 15 has a downwardly recessed rectangular hollow groove 16 inside. A perforated placement plate 17 is fixed inside the top opening of the rectangular hollow groove 16. The perforated placement plate 17 is flush with the top outer wall of the rectangular metal plate 15. The perforated placement plate 17 can directly place the chip with removable parts. The downwardly recessed rectangular hollow groove 16 inside the rectangular metal plate 15 is the core spatial structure of this device. The chip with removable parts is fixed inside the top opening of the rectangular hollow groove 16. The perforated placement plate 17 is flush with the top outer wall of the rectangular metal plate 15, providing a direct placement platform for the chip to be installed or removed. This design ensures that the chip is in a flat and stable position after placement, facilitating precise clamping operations by the chip clamping plates A5 and B6. At the same time, the minimal height difference between the bottom outer wall of the chip clamping plates A5 and B6 and the top outer wall of the rectangular metal plate 15 and the perforated placement plate 17 ensures tightness and stability when clamping the chip, preventing situations where the chip is not firmly clamped or unevenly stressed due to excessive height difference.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, the integrated disassembly and collection device 12 also includes a flat rectangular liquid storage box 18, a pull-out disassembly slot 19, and a rubber anti-detachment block 22. The pull-out disassembly slot 19 is located inside the right end of the rectangular metal plate 15, and it communicates with the interior of a rectangular hollow groove 16. The flat rectangular liquid storage box 18 is located within the rectangular hollow groove 16, below the perforated placement plate 17, with its opening facing upwards. Rubber anti-detachment blocks are provided on the front and rear ends of the rectangular metal plate 15, and on the outer wall of its right end. The flat rectangular liquid storage box 18 can slide directly to the right through the pull-out slot 19. Half of the two rubber anti-detachment blocks 22 are positioned at the front and rear right-side openings of the pull-out slot 19, respectively. These rubber anti-detachment blocks 22 act as a barrier to prevent detachment at the right end of the flat rectangular liquid storage box 18. The height difference between the bottom outer walls of the chip clamps A5 and B6 and the top outer walls of the rectangular metal plate 15 and the perforated placement plate 17 is less than 0.1 mm. To facilitate the collection of waste and liquids during chip assembly and disassembly, the device is equipped with a flat... A rectangular liquid storage box 18 is located within a rectangular hollow groove 16, below a perforated placement plate 17, with its opening facing upwards. A pull-out slot 19, located inside the right end of a rectangular metal plate 15, communicates with the interior of the rectangular hollow groove 16. This provides a channel for installing and removing the flat rectangular liquid storage box 18. Furthermore, during chip installation and removal, waste and liquids can fall directly into the flat rectangular liquid storage box 18 through the holes in the perforated placement plate 17. The design of the flat rectangular liquid storage box 18 fully considers ease of use; it can directly... The device slides out to the right through the pull-out slot 19, facilitating cleaning and replacement after the waste or liquid is full. The rubber anti-detachment blocks 22 installed at both ends of the rectangular metal plate 15 and on the right outer wall play a crucial protective role. Half of the two rubber anti-detachment blocks 22 are respectively blocked at the right openings at both ends of the pull-out slot 19. When the flat rectangular liquid storage box 18 is in normal use, it can effectively prevent it from accidentally sliding out of the rectangular hollow groove 16, ensuring that the liquid storage box is always in the correct working position and maintaining the normal collection function of the device.
