Technical Field

[0001] The utility model belongs to the technical field of clamping devices, and in particular relates to a clamping device for integrated circuit testing. Background Art

[0002] Integrated circuits are tiny electronic components made of semiconductor materials, which integrate many electronic devices on a chip to achieve various functions. Integrated circuits are widely used in computers, communications, consumer electronics, medical equipment and other fields. After the integrated circuit is produced, in order to ensure the quality of the integrated circuit, it may be necessary to test the integrated circuit to ensure the performance and quality of the integrated circuit. When testing the integrated circuit, in order to facilitate the stable fit between the integrated circuit and the test connector, the operator may need to use a clamping device to clamp the integrated circuit and the test frame together during the test. Therefore, it can be seen that the existing clamping device basically meets people's practical needs, but the following problems still exist.

[0003] When the operator is testing the integrated circuit, the operator places the integrated circuit in the card slot of the test fixture, and then the operator presses the fixture to clamp the integrated circuit. When the operator completes the test of the integrated circuit, the operator takes the integrated circuit out of the card slot by pressing the button. However, since the shapes of the general card slot and the integrated circuit match each other, the surface of the integrated circuit may abut against the inner wall of the card slot when the operator presses the button, which may cause the inner wall of the card slot to scratch the surface of the integrated circuit, and may cause scratches on the surface of the integrated circuit. For this reason, we propose a clamping device for integrated circuit testing. Utility Model Content

The second rotating shaft 16 fixed on the inner wall of the rotating slot 14 is penetrated, and the end of the connecting block 15 is fixed with a supporting plate 13, and the surface of the supporting plate 13 is sleeved with a storage opening on the inner wall of the loading slot 5. Slot 12, when the operator needs to take out the tested integrated circuit board from the loading slot 5, the operator first presses the seesaw 7. When the seesaw 7 is subjected to force, the circular through hole opened in the middle of the seesaw 7 rotates on the surface of the first rotating shaft 11 set to be cylindrical, and the seesaw 7 rotates in the avoidance slot 9. The rotating slot 14 opened at the end of the seesaw 7 pushes the connecting block 15 to move through the second rotating shaft 16, so that the seesaw 7 uses the first rotating shaft 11 as a support point, and the end of the seesaw 7 tilts the connecting block 15. When the connecting block 15 moves in the avoidance slot 9, the connecting block 15 pushes the supporting plate 13 to move, so that the supporting plate 13 pushes the integrated circuit board placed in the loading slot 5 to move, and the integrated circuit board is taken out from the loading slot 5. When the operator takes the integrated circuit board out of the loading slot 5, it is no longer necessary to buckle the integrated circuit board out of the loading slot 5 by detent, thereby improving the convenience of the operator taking the integrated circuit board out of the loading slot 5.

[0027] In other embodiments, a plurality of groups of traction grooves 8 intersecting horizontally and vertically are provided in the middle of the mounting plate 4, and a positioning rod 17 is passed through the middle of the traction groove 8. A butt plate 18, a spring 19 and a cushion block 10 are sequentially provided on the surface of the positioning rod 17 from top to bottom. The spring 19 is wound on the surface of the positioning rod 17, and the two side ends of the spring 19 are respectively abutted between the cushion block 10 passed through by the positioning rod 17 and the butt plate 18 fixed on the surface of the positioning rod 17. A butt block 6 is fixed at the end of the positioning rod 17. When the operator needs to install the butt block 6 on the mounting plate 4, the operator first moves the cushion block 10 with his hand, and then the operator pulls the butt block 6. The butt block 6 drives the positioning rod 17 to slide in a rectangular shape in the circular through hole opened in the middle of the cushion block 10, and the positioning rod 17 drives the butt plate 18 to squeeze the spring 19, so that after the spring 19 is elastically deformed, the cushion block 10 and the butt plate 18 are close to each other, and then the operator The author takes the pad 10 and the butt plate 18, inserts the butt plate 18 and the pad 10 into the traction groove 8, and pushes the butt block 6, so that the butt block 6 drives the positioning rod 17 to move. When the butt block 6 moves to the appropriate position and the seesaw 7 is aligned with the circular through hole in the middle of the traction groove 8, the operator releases the butt block 6. After the butt block 6 no longer squeezes the spring 19 through the butt plate 18, the elastic deformation of the spring 19 is restored, and the spring 19 pushes the pad 10 to slide on the surface of the positioning rod 17, so that the pad 10 and the butt plate 18 are in contact with the inner wall of the traction groove 8, and the butt plate 18 drives the positioning rod 17 to pass through the circular through hole in the middle of the traction groove 8, and the butt block 6 is installed at the bottom end of the mounting plate 4, thereby fixing the butt block 6 on the mounting plate 4, which is convenient for the operator to fill or remove the butt block 6, and convenient for the operator to adjust the position of the butt block 6, thereby improving the usability of the operation.

[0028] In other embodiments, the end of the rocker plate 7 away from the stop block 6 is set to a semicircular shape, a circular through hole is opened in the middle of the traction groove 8, and the circular through hole opened in the middle of the traction groove 8 matches the cylindrical shape of the positioning rod 17. Since the end of the positioning rod 17 is set to a semicircular shape, when the operator inserts the semicircular shape set at the end of the positioning rod 17 into the circular through hole opened in the middle of the traction groove 8, the semicircular shape set at the end of the positioning rod 17 is convenient to reduce the surface diameter of the end of the positioning rod 17, thereby facilitating the positioning rod 17 to pass through the circular through hole opened in the middle of the stop plate 18.

[0029] In other embodiments, the cross-sections of the pad block 10 and the abutment plate 18 are both configured as rectangular blocks, and the rectangular blocks configured as the cross-sections of the pad block 10 and the abutment plate 18 match the inner walls of the traction groove 8. When the rectangular blocks configured as the cross-sections of the pad block 10 and the abutment plate 18 match the inner walls of the traction groove 8, after the pad block 10 and the abutment plate 18 are inserted into the traction groove 8, the surfaces of the pad block 10 and the abutment plate 18 fit with the inner walls of the traction groove 8. After the abutment plate 18 and the pad block 10 are inserted into the traction groove 8, the pad block 10 and the abutment plate 18 will not shake at will in the traction groove 8, thereby avoiding shaking of the abutment block 6 when in use, thereby improving the stability of the user of the abutment block 6.

[0030] In other embodiments, the avoidance grooves 9 are all set to have an inclined slope, and the inclined slope of the avoidance grooves 9 matches the seesaw 7. By matching the inclined slope of the avoidance grooves 9 with the seesaw 7, when the operator no longer presses the seesaw 7, the surface of the seesaw 7 fits against the inner wall of the avoidance grooves 9, so that the seesaw 7 can be stably stored in the avoidance grooves 9.

[0031] In other embodiments, a plurality of groups of wavy grooves are provided at the end of the seesaw 7. By providing the wavy grooves at the end of the seesaw 7, when the operator pulls the seesaw 7 to move, after the operator holds the hand on the surface of the end of the seesaw 7, the operator's hand and the plurality of groups of wavy grooves provided at the end of the seesaw 7 fit together, so that the wavy grooves increase the friction force of the operator's hand holding the end of the seesaw 7, thereby increasing the stability of the operator pulling the seesaw 7.
