[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a conveyor 1 and a rocker arm machine 2; the conveyor 1 is located on the right side of the rocker arm machine 2, and the test platform 3 is located on the front side of the rocker arm machine 2;
[0030] It also includes:
[0031] Positioning rod 4 is fixed to the bottom surface of the front end of the rocker arm machine 2, and the movable seat 5 is movably sleeved on the positioning rod 4. The positioning rod 4 plays a positioning role.
[0032] The electric push rod 6 is fixed on the ring wall of the positioning rod 4. The output end of the electric push rod 6 is connected to the moving seat 5. The electric push rod 6 is connected to an external power supply. The position of the moving seat 5 is adjusted by the electric push rod 6. An infrared sensor 22 is fixed on the positioning rod 4. The infrared sensor 22 is electrically connected to the rocker arm machine 2 and the electric push rod 6 to facilitate monitoring the posture of the chip and adjusting the positioning rod 4 to a suitable position.
[0033] The adsorption block 7 is set at the bottom of the movable base 5 by the connecting component 9, and the bottom surface of the adsorption block 7 is provided with adsorption holes 8. The chip is adsorbed onto the adsorption block 7 by adsorption.
[0034] A connecting pipe 10 is provided on the side wall of the adsorption block 7 and is connected to the adsorption hole 8. An air pump 11 is fixed on the movable seat 5 and is connected to the connecting pipe 10 through a pipe. The air pump 11 and the connecting pipe 10 are used to control the air pressure in the adsorption hole 8.
[0035] The contact block 12 is movably disposed within the adsorption hole 8, and the peripheral wall of the contact block 12 is engaged with the inner wall of the adsorption hole 8. An opening 13 is provided through the contact block 12 to facilitate contact between the contact block 12 and the chip, thereby improving the adsorption force. A rubber ring 20 is fixed at the bottom of the contact block 12 and is located at the opening 13. The rubber ring 20 is used to prevent gaps between the contact block 12 and the chip, which would affect the adsorption force. A protective pad 21 is fixed at the bottom of the adsorption block 7 and is fitted onto the contact block 12, allowing the contact block 12 to make flexible contact with the chip and preventing damage to the chip.
[0036] Spring 14 is disposed in adsorption hole 8. The two ends of spring 14 are respectively connected to the inner wall of adsorption hole 8 and contact block 12. The elastic force of spring 14 causes contact block 12 to extend out of adsorption hole 8 and contact the chip.
[0037] Connection component 9 includes;
[0038] The limiting rod 15 is a plurality of such limiting rods 15. The plurality of limiting rods 15 are fixed on the bottom surface of the movable seat 5 and are movably inserted into the adsorption block 7. The limiting rods 15 serve a positioning function and limit the installation position of the adsorption block 7.
[0039] The limiting block 16, there are several limiting blocks 16, and the top of the several limiting blocks 16 are screwed to the annular wall of the adsorption block 7 at equal angles by the spring-loaded rotating shaft. The rotation position of the limiting block 16 is limited by the action of the spring-loaded rotating shaft.
[0040] The limiting ring 17 is sleeved on the movable seat 5, and the limiting block 16 is engaged with the limiting ring 17 to make it easier to temporarily install the adsorption block 7 on the movable seat 5.
[0041] The rotating ring 18 is movably sleeved on the movable seat 5 and threadedly connected to several limiting blocks 16 to restrict the position of the limiting blocks 16 and prevent the adsorption block 7 from falling off. The side walls of the several limiting blocks 16 are fixed with protrusions 19, which are engaged with the rotating ring 18 to restrict the position of the rotating ring 18.
[0042] When using this utility model, the chip is transferred to a suitable position by the conveyor 1, and then the position of the positioning rod 4 is adjusted by the rocker arm machine 2 controlled by the infrared sensor 22 until the positioning rod 4 is moved above the chip. Then the electric push rod 6 is started to control the moving seat 5 to descend. The moving seat 5 drives the adsorption block 7 to descend until the abutting rubber ring 20 on the abutting block 12 abuts against the chip. Then the air pump 11 is started to adjust the air pressure in the suction hole so that the chip is adsorbed on the abutting block 12. At the same time, the abutting block 12 drives the chip to move into the adsorption hole 8. Then the positioning rod 4 is moved above the test table 3 and the chip is placed on the test table 3 for testing.
[0043] Meanwhile, the operator inserts the appropriate adsorption block 7 onto the limiting rod 15 according to the size of the chip, and then clamps the limiting block 16 onto the limiting ring 17, so that the adsorption block 7 is temporarily fixed on the moving seat 5. Then, the rotating ring 18 is screwed onto several limiting blocks 16, so that the rotating ring 18 abuts against the protrusion 19, limiting the displacement of the limiting block 16, so that the adsorption block 7 is fixed on the moving seat 5. Finally, the pipe in the air pump 11 is connected to the connecting pipe 10 with bolts.
[0044] Compared with the prior art, the beneficial effects of this utility model are:
[0045] The position of the positioning rod 4 is controlled by the rocker arm machine 2, and the position of the adsorption block 7 is controlled by the electric push rod 6, so that the contact block 12 abuts against the chip and adsorbs the chip onto the contact block 12, which makes it easy to quickly place the chip on the test stage 3 and improve the efficiency of the test.
[0046] The connecting component 9 is set up, which is engaged by the limiting block 16 and the limiting ring 17, and the position of the limiting block 16 is restricted by the rotating ring 18, so as to facilitate the replacement of the adsorption block 7 to adapt to chips of different sizes.
[0047] A rubber ring 20 is set up to abut against the chip to prevent the gap between the contact block 12 and the chip from affecting the adsorption force.
[0048] The protective pad 21 is provided so that the adsorption block 7 makes flexible contact with the chip, thus avoiding damage to the chip.
[0049] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
