Description

Technical Field

[0001] This utility model relates to the technical field of clamping devices, and in particular to an anti-static chip clamping device. Background Technology

[0002] A chip refers to an integrated circuit, a method of miniaturizing circuits, often manufactured on the surface of a semiconductor wafer. Strictly speaking, the true meaning of a chip refers to a tiny semiconductor chip inside an integrated circuit package, also known as a die. Whether it's a chip or a die, it requires reliability testing after manufacturing. When performing small-batch chip testing, a simple workbench is typically used to fix the chips. For example, patent CN219189888U discloses a chip testing clamping fixture. This fixture uses a first clamping plate and a first spring to clamp and fix chips of different widths for testing. The cooperation of the first and second clamping plates allows for the fixing and testing of longer chips. This allows for the testing of chips of different specifications, making it widely applicable. An anti-slip plate increases the clamping friction, preventing the chip from slipping out of the clamping plate. However, when using the first clamping plate and first spring to clamp the chip, because the user has difficulty controlling the spring's preload, the chip may be damaged due to excessive preload when the first clamping plate contacts the chip. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an anti-static chip clamping device that can detect both sides of the chip, facilitates adjustment of the clamping force according to actual needs, and avoids damage to the chip due to excessive pre-tightening force.

[0004] This utility model discloses an anti-static chip clamping device, comprising two clamping seats, two connecting rods, a clamping component, and a pressure adjusting component. The two clamping seats are connected and fixed together by the connecting rods to form a whole. The clamping component is installed on the clamping seat, and the pressure adjusting component is installed on the clamping component. When it is necessary to clamp the chip, the user places the chip between the two clamping seats, and the clamping component clamps the chip. The pressure adjusting component can detect both sides of the chip, so as to adjust the clamping force according to the actual needs and avoid excessive pre-tightening force that could damage the chip.

[0005] Preferably, the clamping component includes two clamping slides, two pull frames, two springs, two sets of clamping rods, two mounting seats, and two clamping plates. The clamping seats have clamping grooves at their top ends, and the clamping slides are slidably installed within these grooves. Pull frames are mounted at the top of the clamping slides, positioned above the clamping seats. Springs are connected to the inner wall of the clamping slides. Clamping rods are symmetrically mounted on the clamping slides, sliding through the clamping grooves to mount the mounting seats, which in turn mount the clamping plates. When clamping the core is required, the user pulls the pull frames to place the core between the two clamping plates. Releasing the pull frames allows the springs to push the clamping slides to move within the clamping grooves, and the clamping rods push the clamping plates to pre-clamp the core.

[0006] Preferably, the pressure regulating component includes two pressure sensors, two threaded pins, two regulating motors, two threaded sleeves, and a controller. The pressure sensors are installed inside the mounting base and connected to the clamping plate. The threaded pins are rotatably mounted on the outer wall of the clamping base at the end away from the clamping slide. The regulating motors are mounted on the outer wall of the clamping base, and their output ends are connected to the output ends of the threaded pins. The threaded sleeves are screwed onto the outer wall of the threaded pins. The end of the spring away from the clamping slide is connected to the threaded sleeve. A fixing groove is provided at the front end of the clamping base, and the controller is installed in the fixing groove. The pressure sensors can detect both sides of the core. According to actual needs, the regulating motors are started to drive the threaded pins to rotate, adjusting the position of the threaded sleeves, thereby adjusting the spring force and avoiding excessive preload that could damage the chip.

[0007] Preferably, it also includes two support rods and two limiting sliders. A limiting groove is formed at the bottom of the clamping groove, and a limiting slider is installed at the bottom of the threaded sleeve. The limiting slider is slidably installed in the limiting groove. A rotating groove is formed inside the threaded column. One end of the support rod is rotatably installed in the rotating groove of the threaded column, and the other end of the support rod is installed on the inner wall of the clamping groove. The spring is sleeved on the outer wall of the support rod, and the clamping slide plate and the threaded sleeve are slidably installed on the outer wall of the support rod. When the threaded sleeve moves, it drives the limiting slider to move in the limiting groove, limiting and guiding it to ensure stability. At the same time, the support rod can position the spring to prevent it from popping out and affecting its use, thus ensuring the stability of clamping.

[0008] Preferably, it also includes two sets of limiting slide rods. The limiting slide rods are fixedly installed on the front and rear sides of the clamping slide groove, and the front and rear ends of the lower part of the clamping slide are slidably installed on the outer wall of the limiting slide rods. When the clamping slide moves, it slides on the limiting slide rods to limit and guide it, avoid tilting and jamming, and ensure stability.

[0009] Preferably, the clamping plate is made of plastic and has an anti-slip plate on its outer surface; the plastic material is not easy to scratch the chip, and the plastic has an anti-static function to prevent static electricity from damaging the chip. The anti-slip plate increases the clamping friction and prevents the chip from slipping out of the clamping plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: when it is necessary to clamp the core, the user places the core between two clamping seats and clamps the core through the clamping components. The pressure adjustment components can detect both sides of the core, making it easy to adjust the clamping force according to actual needs, and avoid excessive pre-tightening force that could damage the chip.

Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0013] like Figures 1 to 5As shown, two clamping seats 1 are connected and fixed together by a connecting rod 2, forming a whole. A clamping groove is opened at the top of the clamping seat 1, and the clamping slide plate 3 is slidably installed in the clamping groove. A pulling frame 4 is installed at the top of the clamping slide plate 3, and the pulling frame 4 is located above the clamping seat 1. A spring 5 is connected to the inner wall of the clamping slide plate 3. Clamping rods 6 are symmetrically installed on the clamping slide plate 3. The clamping rods 6 slide through the clamping groove and are installed on the mounting seat 7. A clamping plate 8 is installed on the mounting seat 7. A pressure sensor 9 is installed inside the mounting seat 7 and is connected to the clamping plate 8. A threaded column 10 is rotatably installed on the outer wall of the clamping seat 1 at the end away from the clamping slide plate 3. An adjusting motor 11 is installed on the outer wall of the clamping seat 1. The output end of the adjusting motor 11 is connected to the output end of the threaded column 10.

A fixed groove is opened at the front end of the clamping seat 1, and the controller 15 is installed in the fixed groove. A limit groove is opened at the bottom of the clamping slide. A limit slider 14 is installed at the bottom of the threaded sleeve 13. The limit slider 14 is slidably installed in the limit groove. A rotating groove is opened inside the threaded column 10. One end of the support rod 12 is rotatably installed in the rotating groove of the threaded column 10. The other end of the support rod 12 is installed on the inner wall of the clamping slide. The spring 5 is fitted on the outer wall of the support rod 12, and the clamping slide plate 3 and the threaded sleeve 13 are slidably installed on the outer wall of the support rod 12. Limiting rods 16 are fixedly installed on the front and rear sides of the clamping slide. The front and rear ends of the lower part of the clamping slide plate 3 are slidably installed on the outer wall of the limiting rods 16. The clamping plate 8 is made of plastic and has an anti-slip plate on its outer surface. When the chip needs to be clamped, the user pulls the pull frame 4 to place the chip between the two clamping plates 8. Releasing the pull frame 4 pushes the clamping slide plate 3 to move within the clamping groove via the spring 5. The clamping rod 6 pushes the clamping plates 8 to pre-clamp the chip. The pressure sensor 9 can detect both sides of the chip. As needed, the adjusting motor 11 is started to drive the threaded column 10 to rotate, adjusting the position of the threaded sleeve 13, thereby adjusting the elasticity of the spring 5 to avoid excessive pre-tightening force that could damage the chip. When the threaded sleeve 13 moves, it drives the limiting slider 14 to move within the limiting groove, limiting and guiding it to ensure stability. At the same time, the support rod 12 can position the spring 5 to prevent it from popping out and affecting use, ensuring clamping stability. When the clamping slide plate 3 moves, it slides on the limiting slide rod 16 to limit and guide it to avoid tilting and jamming, ensuring stability. The plastic material is not easy to scratch the chip, and the plastic has an anti-static function to prevent static electricity from damaging the chip. The anti-slip plate increases the clamping friction to prevent the chip from slipping out of the clamping plate.

[0014] like Figures 1 to 5As shown, this utility model discloses an anti-static chip clamping device. During operation, when a chip needs to be clamped, the user pulls the pull frame 4 to place the chip between two clamping plates 8. Releasing the pull frame 4 causes the clamping slide plate 3 to move within the clamping groove via a spring 5. As the clamping slide plate 3 moves, it slides on the limiting slide rod 16 for limiting and guiding, preventing tilting and jamming. The clamping rod 6 pushes the clamping plates 8 to pre-clamp the chip. A pressure sensor 9 can detect both sides of the chip. As needed, the adjusting motor 11 is activated to rotate the threaded column 10, adjusting the position of the threaded sleeve 13, thereby adjusting the spring force of the spring 5 to prevent excessive pre-tightening force from damaging the chip. As the threaded sleeve 13 moves, it causes the limiting slider 14 to move within the limiting groove for limiting and guiding, ensuring stability. Simultaneously, the support rod 12 positions the spring 5 to prevent it from popping out and affecting use.
