Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, and in particular to an adjustable clamping fixture for semiconductor discrete devices. Background Technology
[0002] In the field of semiconductor discrete device manufacturing and processing, there are stringent requirements for the performance of fixtures;
[0003] In the manufacturing process of semiconductor discrete devices, the horizontal adjustment of the fixture base is crucial. During production, factors such as equipment vibration and minor unevenness of the workshop floor can cause changes in the horizontality of the fixture base, requiring frequent horizontal adjustment operations using tools, which reduces the convenience of base horizontal adjustment. Semiconductor discrete devices come in various shapes, including cylindrical, flat, and irregular polygonal shapes. However, traditional fixtures have a single and fixed clamping surface, making it difficult to adapt to diverse device shapes. When dealing with discrete devices of different shapes, it is often necessary to frequently change the entire set of fixtures, reducing the versatility of the fixtures. In the same production line, if multiple shapes of discrete devices need to be processed, using traditional fixtures will consume a lot of time due to frequent clamp changes, reducing work efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The system includes: a base 1, an adjustment structure 2, a conversion structure 3, and a discrete component body 4. Two adjustment structures 2 are respectively provided on both sides of the base 1. Each adjustment structure 2 includes a fixing plate 5 and a threaded rod 6. One end of the fixing plate 5 is fixedly connected to the outer surface of the base 1. A threaded hole is formed on the upper surface of the fixing plate 5, and the threaded rod 6 is threadedly connected inside the threaded hole. An installation groove is formed on the upper surface of the base 1. A sliding groove is formed at the bottom of the installation groove on the upper surface of the base 1. Two sliding blocks 7 are slidably connected inside the sliding groove at the bottom of the installation groove on the upper surface of the base 1. A base plate 8 is fixedly connected to the upper surface of each of the two sliding blocks 7. A conversion structure 3 is provided on the upper surface of each of the two base plates 8. A conversion clamp 9 is provided above the two conversion structures 3. One side of the conversion clamp 9 has anti-slip texture, and the other side of the conversion clamp 9 is arc-shaped and has anti-slip texture. When facing the discrete device body 4, the friction between the two components can be increased, effectively preventing the discrete device body 4 from sliding during clamping. When different shapes of discrete device bodies 4 need to be clamped, the arc-shaped surface of the conversion fixture 9 can fit the shape of the discrete device body 4 for better clamping and fixing. Through the connection with the rotating rod 11, the anti-slip textured surface and the arc-shaped surface can be switched under the drive of the conversion structure 3 to adapt to different clamping requirements. The discrete device body 4 is clamped between the two conversion fixtures 9. The conversion structure 3 includes a rotating rod 11, a worm wheel 12 and a worm 13. The worm wheel 12 is fixedly connected to the lower outer surface of the rotating rod 11. The worm 13 is meshed on one side of the worm wheel 12. When the worm 13 rotates, it meshes with the worm wheel 12, causing the worm wheel 12 to rotate. When the worm wheel 12 rotates, it drives the rotating rod 11 to rotate.
[0020] In the specific implementation process, a bearing plate 14 is fixedly connected to one end of the outer surface of the base 1. A through hole is opened on one end of the outer surface of the base 1. The through hole on one end of the outer surface of the base 1 is connected to the bottom sliding groove in the mounting groove on the upper surface of the base 1. The base 1 serves as the basic support component of the fixture, providing stable support for the entire device. The two sides of the base 1 are used to install the adjustment structure 2. The mounting groove opened on the upper surface of the base 1 provides installation space for other components. The sliding groove at the bottom of the mounting groove is used for the movement of the sliding block 7. The bearing plate 14 on one end of the outer surface of the base 1 provides an installation position for the first servo motor 19. The through hole opened on one end of the outer surface of the base 1 allows the bottom sliding groove in the mounting groove to communicate with the outside, facilitating the passage of the positive and negative threaded rods 18 and their connection with the first servo motor 19, while not hindering the rotation of the positive and negative threaded rods 18.
[0021] The threaded rod 6 has a knob 15 fixedly connected to its upper end and a connecting plate 16 rotatably connected to its lower end. A suction cup 17 is installed on the lower surface of the connecting plate 16. The connecting plate 16 is used to install the suction cup 17. The knob 15 allows the operator to manually operate the threaded rod 6. By rotating the knob 15, the threaded rod 6 can be raised or lowered, thereby adjusting the connecting plate 16 and the suction cup 17 to adjust the height of the suction cup 17. The suction cup 17 can be attached to a support surface such as a workbench, enhancing the connection stability between the base 1 and the workbench and preventing the fixture from shifting during operation.
[0022] Both sliding blocks 7 have threaded holes at one end, and a positive and negative threaded rod 18 is threaded into the threaded holes at one end of each sliding block 7. One end of the positive and negative threaded rod 18 is rotatably connected to the inner wall of the bottom sliding groove in the mounting groove on the upper surface of the base 1. The other end of the positive and negative threaded rod 18 extends through a through hole on the outer surface of one end of the base 1 to the outer surface of the base 1. A first servo motor 19 is provided at the end of the positive and negative threaded rod 18 extending to the outer surface of the base 1. The power output end of the first servo motor 19 is fixedly connected to the end of the positive and negative threaded rod 18 near the first servo motor 19. The lower surface of the first servo motor 19 is fixedly connected to the upper surface of the support plate 14. 4 is used to support the first servo motor 19, providing a stable mounting platform for the first servo motor 19 and ensuring the stability of the first servo motor 19 during operation. The first servo motor 19 is electrically connected to an external power supply. When the first servo motor 19 is started, the power output end of the first servo motor 19 rotates, driving the positive and negative threaded screw 18 to rotate. When the positive and negative threaded screw 18 rotates, due to its positive and negative thread structure, the two sliding blocks 7 can move relative to each other or in opposite directions. When the two sliding blocks 7 move relative to each other, they drive the conversion clamp 9 to clamp the discrete device body 4. When the two sliding blocks 7 move in opposite directions, the discrete device body 4 can be removed.
[0023] Two ear plates 20 are fixedly connected to the upper surface of the base plate 8. The side surfaces of the two ear plates 20 are provided with through holes. A fixing frame 10 is fixedly connected to the upper surface of the base plate 8. The upper surface of the fixing frame 10 is provided with through holes. The lower end of the rotating rod 11 is rotatably connected to the upper surface of the base plate 8. The rotating rod 11 is rotatably connected to the inside of the through hole on the upper surface of the fixing frame 10. The through hole on the upper surface of the fixing frame 10 is used to rotatably connect the rotating rod 11, providing a stable support structure for the rotation of the rotating rod 11, ensuring that the rotating rod 11 can rotate smoothly around its own axis. The upper ends of the rotating rod 11 in the two conversion structures 3 are fixedly connected to the lower surfaces of the two conversion clamps 9. When the rotating rod 11 rotates, it drives the conversion clamps 9 to rotate around the axis of the rotating rod 11, so that the conversion clamps 9 can switch between the anti-slip textured surface and the arc surface. The base plate 8 transmits the movement of the sliding block 7 to the conversion structure 3, so that the conversion structure 3 and the conversion clamps 9 can adjust their positions as the sliding block 7 moves.
[0024] The worm gear 13 is rotatably connected at both ends to the through holes on the side surfaces of the two ear plates 20. A second servo motor 21 is provided at one end of the worm gear 13. The power output end of the second servo motor 21 is fixedly connected to the end of the worm gear 13 near the second servo motor 21. The bottom of the second servo motor 21 is fixedly connected to the upper surface of the base plate 8. The second servo motor 21 is electrically connected to an external power source. When the second servo motor 21 is started, the power output end of the second servo motor 21 rotates, causing the worm gear 13 to rotate inside the through holes on the side surfaces of the two ear plates 20.
[0025] The working principle of this utility model is as follows: First, place the base 1 on the workbench. The operator manually rotates the knob 15 on the threaded rod 6 in the adjustment structure 2. The knob 15 drives the threaded rod 6 to move up and down in the threaded hole of the fixed plate 5, thereby causing the connecting plate 16 and the suction cup 17 to rise and fall, adjusting the base 1 to a horizontal state. Then, the suction cup 17 is firmly attached to the workbench to stabilize the base 1. The operator starts the first servo motor 19. The motor's power output drives the positive and negative threaded screw 18 to rotate. Based on the special structure of the positive and negative threaded screw 18, the two sliding blocks 7 threadedly connected to it will move relative to each other according to the rotation direction of the screw. The movement of the sliding blocks 7 causes the fixed base plate 8, the conversion structure 3, and the conversion clamp 9 above them to move closer together. When the two conversion clamps 9 are close to the appropriate position, the discrete device body 4 can be firmly clamped in the middle. If a special shape is encountered... When the clamping surface of the discrete component body 4 needs to be adjusted, the operator starts the second servo motor 21 before clamping the discrete component body 4. The motor's power output drives the worm gear 13 to rotate. The worm gear 13 meshes with the worm wheel 12, causing the worm wheel 12 and the rotating rod 11 fixed on the upper end of the worm wheel 12 to rotate. The rotation of the rotating rod 11 causes the conversion clamp 9 connected to its upper end to rotate around the axis of the rotating rod 11, realizing the flexible switching between the anti-slip textured surface and the arc surface. The operator can select the appropriate clamping surface according to the actual shape of the discrete component body 4 to achieve the best fixing effect. After completing the processing operation of the discrete component body 4, the first servo motor 19 is started again to control the forward and reverse threaded rods 18 to rotate in opposite directions. At this time, the two sliding blocks 7 move in opposite directions, causing the conversion clamp 9 to move away, and the operator can then easily remove the discrete component body 4.
