[0003] The existing probe card level adjustment usually uses a hollow cylindrical part and adjusts the level by adding or removing gaskets.

[0031] The following is combined with Figure 1 —5 Further details of this application are provided.
[0032] The embodiment of the present application discloses a probe card component that can quickly and accurately adjust the level.
[0033] Reference Figure 1 , Figure 2 and Figure 3 A probe card part capable of quickly and accurately adjusting the level comprises a connecting column 1, a fixing ring 2 is fixedly connected to the outer wall of the connecting column 1, a quick interface 3 is fixedly connected to one end of the connecting column 1, a plurality of card slots 4 are evenly arranged on the top of the quick interface 3, an external thread 5 is arranged on the outer wall of the connecting column 1, a rotating column 6 is rotatably connected to the outer wall of the quick interface 3, a plurality of cavities 7 are evenly penetrated and opened on the inner wall of the quick interface 3, a plurality of cavities 7 are slidably connected to the inside of the plurality of cavities 7, a ejection assembly is installed inside the plurality of cavities 7, and a self-locking member is installed inside the quick interface 3; Secondly, the connecting column 1 and the quick interface 3 are hollow inside, the connecting column 1, the fixing ring 2 and the quick interface 3 are all an integral whole, the connecting column 1 and the fixing ring 2 are made of aluminum alloy, the quick interface 3 and the rotating column 6 are also made of aluminum alloy, the pitch of the external thread 5 is 0.0252mm, and the depth of the external thread 5 is 0.5mm.
[0034] When in use, first take out the entire part. When it is necessary to adjust based on the flatness of the use surface of the probe card product, the external thread 5 can be threadedly connected to the probe card body to achieve rapid locking and release with the probe card, and the height can be precisely adjusted by accurately controlling the number of rotations. Each time the part is rotated one circle, the height change is 0.252mm. Through precise calculation, it can be achieved that every 10° adjustment corresponds to a height change of 0.007mm, and there is no need to use the method of adding gaskets to adjust the horizontality. The fine thread design allows for rapid adjustment, improves production efficiency, and ensures the tiny steps and accuracy of height adjustment through precise thread design. The connecting column 1, the fixing ring 2 and the quick interface 3 are all processed as a whole, which can effectively reduce the error in the assembly process. After the pitch and depth of the external thread 5 are accurately calculated, the height can be fine-tuned and precisely controlled, making the adjustment method more convenient, improving the manufacturing efficiency of the probe card, and the stability and reliability of the product; Secondly, after the part is connected to the probe card through the external thread 5, the probe can be inserted into the hollow inside the connecting column 1 and the quick interface 3. At this time, the rotating column 6 can be gently rotated on the quick interface 3 to drive the internal ejection assembly to operate. Through the operation of the ejection assembly, multiple extrusion plates 8 can be gradually ejected from the cavity 7, so that the multiple extrusion plates 8 gradually clamp and resist the probe inside the part. In this way, through the cooperation of multiple extrusion plates 8 and the card slot 4, the probe can be stabilized inside the quick interface 3, so that the probe can reduce the possibility of deviation or loosening during the test process, so as not to reduce the accuracy and reliability of the test, and greatly simplify the disassembly and assembly process with the probe. In addition, when the rotating column 6 is rotated to drive the ejection assembly to operate, it will also drive the self-locking part to operate together. Through the operation of the self-locking part, the position of the ejection assembly can be positioned, so that the ejection assembly can always keep ejecting the extrusion plate 8, which greatly improves the stability of the probe and reduces the loosening of the probe. Secondly, the main body of the part is made of high-strength aluminum alloy material to reduce weight and improve corrosion resistance.
[0035] Reference Figure 2 , Figure 3 and Figure 4The ejection assembly includes a through groove 11 that penetrates and is opened on the outer wall of the quick interface 3. A linkage block 13 is rotatably connected inside the through groove 11. A plurality of fixed rods 12 are evenly fixedly connected inside the rotating column 6. One end of the linkage block 13 is rotatably connected to the fixed rod 12. The end of the linkage block 13 away from the fixed rod 12 abuts against one side of the extrusion plate 8. A groove is provided at the end of the linkage block 13 away from the fixed rod 12. A connecting shaft 14 is rotatably connected inside the groove. A roller 15 is rotatably connected to the connecting shaft 14. The roller 15 is located inside the groove. The roller 15 abuts against one side of the extrusion plate 8. Slide grooves 9 are provided on both sides of the inner walls of the multiple cavities 7, guide plates 10 are fixedly connected on both sides of the multiple extrusion plates 8, the two guide plates 10 are slidably connected to the corresponding insides of the slide grooves 9, and polyurethane elastic gaskets 21 are fixedly connected to the insides of the two slide grooves 9, one end of the polyurethane elastic gasket 21 is fixedly connected to one end of the inner wall of the slide groove 9, and one end of the polyurethane elastic gasket 21 away from the inner wall of the slide groove 9 is fixedly connected to one end of the guide plate 10, the insides of the multiple through grooves 11 are fixedly connected to the central shaft 16, and the middle sections of the multiple linkage blocks 13 are rotatably connected to the central shaft 16.
[0036] When in use, first gently rotate the rotating column 6 to rotate, thereby driving the multiple fixed rods 12 inside to rotate. Since one end of the linkage block 13 is rotatably connected to the fixed rod 12, the one end of the linkage block 13 will move along with the fixed rod 12. At this time, guided by the central axis 16, the linkage block 13 will rotate inside the through groove 11 with the central axis 16 as the center of the circle. As the linkage block 13 rotates, the linkage block 13 will gradually change from an inclined state to a vertical state, so that the roller 15 will move along one side of the extrusion plate 8 and gradually apply an extrusion force to one side of the extrusion plate 8. After the extrusion plate 8 is squeezed, it moves along the direction of the slide groove 9 according to the guidance of the guide plate 10 until it extends out from the cavity 7 and passes through multiple extrusion plates. The gradual extension of 8 can clamp and resist the probe inside the part, so that the probe can be stabilized inside the quick interface 3 through the cooperation of multiple extrusion plates 8 and the card slot 4, so that the probe can be less likely to deviate or loosen during the test, so as not to reduce the accuracy and reliability of the test. When it is necessary to release the installation of the probe, the rotating column 6 can be rotated in the opposite direction to drive the fixing rod 12 to reverse, so that the linkage block 13 gradually changes from a vertical state to an inclined state. At this time, the extrusion force between the roller 15 and one side of the extrusion plate 8 gradually decreases. Therefore, the rebound of the polyurethane elastic gasket 21 will drive the multiple extrusion plates 8 to return to the inside of the cavity 7, so as to release the clamping stability of the probe. At this time, the probe can be pulled out, which greatly simplifies the disassembly and assembly process of the probe.
[0037] Reference Figure 3 and Figure 5The self-locking member includes a plurality of interference blocks 17 uniformly and fixedly connected to the outer wall of the quick interface 3, and the plurality of interference blocks 17 are located at the bottom of the through groove 11. A built-in groove 18 is provided at the bottom of the linkage block 13, and a limit block 19 is slidably connected inside the built-in groove 18. A slider 20 is symmetrically and fixedly connected to the outer wall of the limit block 19, and guide grooves 22 are provided on both sides of the inner wall of the built-in groove 18. The slider 20 is slidably connected inside the guide groove 22. The bottom end of the limit block 19 is arc-shaped, and the spacing between two adjacent interference blocks 17 is the same. The top surfaces of the plurality of interference blocks 17 are all arc-shaped.
[0038] When in use, as the fixing rod 12 drives the linkage block 13 to rotate, the limit block 19 at the bottom of the linkage block 13 will be driven to move together. Because the outer wall of the quick interface 3 is provided with multiple interference blocks 17 and located at the bottom of the through groove 11, when the limit block 19 moves, the arc-shaped end at the bottom of the limit block 19 will contact the arc-shaped surfaces at the top of the multiple interference blocks 17. At this time, the guidance of the arc-shaped end of the limit block 19 and the pressure generated by the interference with the arc-shaped surface of the interference block 17 will make the limit block 19 enter the interior of the built-in groove 18 according to the guidance of the slider 20 and the guide groove 22 after contacting the interference block 17, and as the linkage 3 is rotated, the limit block 19 will enter the interior of the built-in groove 18 according to the guidance of the slider 20 and the guide groove 22. When the movable block 13 continues to rotate and drives the limit block 19 to move between the two resistance blocks 17, the limit block 19 will lose the squeezing of the resistance block 17. According to the influence of gravity, the limit block 19 will naturally extend from the inside of the built-in groove 18, so that the extended limit block 19 is between the two resistance blocks 17. At this time, the position of the linkage block 13 can be automatically locked through the interception and limitation of the two resistance blocks 17. In the absence of external force, the linkage block 13 will not shake significantly, so that the roller 15 can always keep the extrusion plate 8 out, which greatly improves the stability of the probe and reduces the looseness of the probe.
[0039] The implementation principle of the probe card part that can quickly and accurately adjust the level of this embodiment is as follows: when in use, first take out the whole part. When it is necessary to adjust based on the flatness of the use surface of the probe card product, it can be threadedly connected to the probe card body through the external thread 5, so as to achieve rapid locking and release between the probe card and the probe card. The height can be accurately adjusted by accurately controlling the number of rotations. Each time the part rotates one circle, the height change of the part is 0.252mm. Through precise calculation, it can be achieved that every 10° adjustment corresponds to a height change of 0.007mm, and there is no need to use the method of adding gaskets to adjust the level. In this way, the fine thread design allows for rapid adjustment, improves production efficiency, and ensures the small steps and accuracy of height adjustment through precise thread design. The connecting column 1, the fixing ring 2 and the quick interface 3 are all processed as a whole, which can effectively reduce the error in the assembly process. After the pitch and depth of the external thread 5 are accurately calculated, the height can be fine-tuned and precisely controlled, making the adjustment method more convenient, improving the manufacturing efficiency of the probe card, and the stability and reliability of the product. Secondly, after the part is connected to the probe card through the external thread 5, the probe can be inserted into the hollow space inside the connecting column 1 and the quick interface 3. At this time, the rotating column 6 can be rotated by gently turning it to drive the multiple fixed rods 12 inside to rotate. Since one end of the linkage block 13 is rotationally connected to the fixed rod 12, the one end of the linkage block 13 will move along with the fixed rod 12. At this time, guided by the central axis 16, the linkage block 13 will rotate inside the through groove 11 with the central axis 16 as the center of the circle. As the linkage block 13 rotates, the linkage block 13 will gradually change from an inclined state to a vertical state. Therefore, the roller 15 will move along one side of the extrusion plate 8 and gradually apply an extrusion force to one side of the extrusion plate 8. When the extrusion plate 8 is extruded, it will move along the direction of the slide groove 9 according to the guidance of the guide plate 10. The probe 8 is moved until it extends out from the cavity 7. The probe inside the part can be clamped and resisted by the gradual extension of the multiple extrusion plates 8. The probe can be stabilized inside the quick interface 3 by the cooperation of the multiple extrusion plates 8 and the card slot 4. The probe can be reduced in the test process to reduce the possibility of deviation or loosening, so as not to reduce the accuracy and reliability of the test. When it is necessary to release the installation of the probe, the rotating column 6 can be rotated in the opposite direction to drive the fixing rod 12 to reverse, so that the linkage block 13 gradually changes from a vertical state to an inclined state. At this time, the extrusion force between the roller 15 and one side of the extrusion plate 8 gradually decreases. Therefore, the rebound of the polyurethane elastic gasket 21 will drive the multiple extrusion plates 8 to return to the cavity 7, so as to release the clamping stability of the probe. At this time, the probe can be pulled out, which greatly simplifies the disassembly and assembly process of the probe. In addition, as the fixing rod 12 drives the linkage block 13 to rotate, the limit block 19 at the bottom of the linkage block 13 will be driven to move together. Since the outer wall of the quick interface 3 is provided with multiple interference blocks 17 and is located at the bottom of the through groove 11, when the limit block 19 moves, the arc-shaped end at the bottom of the limit block 19 will contact the arc-shaped surfaces at the top of the multiple interference blocks 17. At this time, the pressure generated by the guidance of the arc-shaped end of the limit block 19 and the interference with the arc-shaped surface of the interference block 17 will make the limit block 19 enter the interior of the built-in groove 18 according to the guidance of the slider 20 and the guide groove 22 after contacting the interference block 17, and as the linkage block 13 continues to rotate, the limit block 19 is driven to move When it reaches between the two resistance blocks 17, the limit block 19 will lose the extrusion of the resistance block 17. According to the influence of gravity, the limit block 19 will naturally extend from the inside of the built-in groove 18, so that the extended limit block 19 is between the two resistance blocks 17. At this time, the position of the linkage block 13 can be automatically locked through the interception and limitation of the two resistance blocks 17. In the absence of external force, the linkage block 13 will not shake significantly, so that the roller 15 can always keep the extrusion plate 8 out, which greatly improves the stability of the probe and reduces the looseness of the probe. Secondly, the main body of the parts is made of high-strength aluminum alloy to reduce weight and improve corrosion resistance.
