Description

Technical Field

[0001] The invention relates to the technical field of chip testing devices, in particular to a chip fixing device and a chip testing seat for facilitating chip installation and removal. Background Art

[0002] Before the chips are packaged and manufactured and shipped out, they must go through multiple testing procedures to screen and eliminate defective products, maintain the quality of their chip products, and avoid increasing the cost of subsequent product maintenance. When testing the chips, a chip test socket is required.

[0003] In the prior art, for example, a Chinese patent with publication number CN220626431U proposes an opening and closing claw quick-clamping chip test socket. Under normal conditions, the spring is in a compressed state, giving an upward force to the unlocking member, thereby driving the two operating ends to move upward, so that the abutting end abuts against the chip surface to fix the chip. When the unlocking plate drives the unlocking block to move downward, the transverse groove drives the adjustment shaft to move downward, and the inclined groove forces the adjustment shaft to move in the direction away from the placement groove, thereby realizing that the adjustment shaft drives the operating end to move downward and away from the placement groove, thereby releasing the lock of the fixed claw on the chip.

[0004] In the above technical solution, when taking out the chip, the staff generally needs to hold tweezers or other auxiliary tools and reach into the placement slot through the avoidance slot on the unlocking part to take out the chip. However, since the unlocking part is located above the chip, the chip may hit the unlocking part during the process of taking out the chip, which interferes with the chip taking. Therefore, it is inconvenient to take out the chip from the above chip test socket. Summary of the invention

[0048] 5. When the chip fixture needs to be removed due to damage or maintenance, the staff presses the trigger block to make the trigger block drive the pressure block to move downward through the trigger rod, and through the guiding effect of the inclined surface of the pressure block and the inclined surface of the slide plate, and the cooperation of the two inclined surfaces, the pressure block pushes the slide plate to slide in the slide groove three during the downward pressing process, and the push block slides accordingly. Similarly, through the guiding effect of the inclined surface of the push block and the inclined surface of the lower end of the push rod, and the cooperation of the two inclined surfaces, the push block lifts the push rod during the horizontal movement, and the push rod lifts the connecting rod, and the chip fixture is also lifted accordingly, and the fixing ring on the side surface of the connecting rod slides out of the slot, and then the chip fixture is removed, completing the disassembly of the chip fixture, and setting the spring two can make the slide plate drive the push block to automatically return to its position, and the spring three can make the trigger block automatically return to its position, so that the chip test socket can conveniently and quickly remove the chip fixture, greatly shortening the time for replacing the chip fixture.

The diameter of the trigger rod 92 is the same as the diameter of the second sliding hole 64, and the lower end of the trigger rod 92 passes through the second sliding hole 64 and is fixedly connected to the upper surface of the pressing block 9.

[0112] like Fig.10 and Fig.11 As shown, a spring 3 200 is provided in the pressing hole 63 , the spring 3 200 is sleeved outside the trigger rod 92 , and the spring 3 200 is fixedly connected between the trigger block 91 and the bottom of the pressing hole 63 .

[0113] According to the present invention, after the chip detection is completed, the pressing plate 21 is pressed downward, and the pressing plate 21 slides downward along the guide angle plate 12, the free end of the tilting portion of the tilting rod 4 moves downward, and the free end of the horizontal portion of the tilting rod 4 drives the protrusion 42 to move upward, and pushes the contact plate 32 upward, and the protrusion 42 slides toward the center of the contact plate 32 along the guide groove 324, and rotates with the change of the angle of the horizontal portion of the tilting rod 4, and the guide frame 31 moves upward accordingly, and the tilting rod 4 moves toward the center of the bottom plate 11 as a whole, and the sliding bars 41 on both sides of the bending starting point of the tilting rod 4 move in the slide groove 15 along the movement of the tilting rod 4 The chip continues to move upward when the guide frame 31 contacts the lower surface of the pressing plate 21, and the contact plate 32 drives the chip to continue to move upward. The limiting groove 321 on the lower surface of the contact plate 32 leaves the limiting rod 313 at the lower end of the inner wall of the guide frame 31. After the contact plate 32 abuts against the lower surface of the pressing plate 21, the limiting rod 313 at the upper end of the inner wall of the guide frame 31 is inserted into the limiting groove 321 on the upper surface of the contact plate 32. The chip is pushed into the placement hole 24 in the positioning groove 321, and finally the staff holds tweezers or other auxiliary tools and reaches into the clamping port 25 to take out the chip. In this way, the chip can be quickly taken out of the fixing device. The operation is simple and convenient, and the chip detection efficiency can be further improved. After the chip is taken out, the pressing plate 21 is released, and the spring 15 pushes up the pressing plate 21, and the free end of the lifting part of the tilting rod 4 moves upward, and the free end of the horizontal part of the tilting rod 4 moves downward, and the tilting rod 4 moves away from the center of the bottom plate 11 as a whole, and the horizontal part of the tilting rod 4 re-enters the guide When the guide frame 31 contacts the upper surface of the bottom plate 11, the contact plate 32 continues to move downward, and the limiting groove 321 on the upper surface of the contact plate 32 leaves the limiting rod 313 at the upper end of the inner wall of the guide frame 31. After the contact plate 32 abuts against the upper surface of the bottom plate 11, the limiting rod 313 at the lower end of the inner wall of the guide frame 31 is inserted into the limiting groove 321 on the lower surface of the contact plate 32. In this way, the pressing mechanism 2 and the fixing seat 3 can automatically return to their original positions under the action of the spring 1 5.

[0114] When the chip fixing device needs to be removed due to damage or maintenance, the staff can press the trigger block 91, the spring three 200 is compressed, and the trigger block 91 drives the pressing block 9 to move downward through the trigger rod 92. The inclined surface of the pressing block 9 cooperates with the inclined surface of the slide plate 8, so that the pressing block 9 pushes the slide plate 8 to slide in the slide groove three 66 during the downward pressing process, and the push block 81 slides accordingly, the spring two 100 is compressed, and the inclined surface of the push block 81 cooperates with the inclined surface of the lower end of the push rod 400, so that the push block 81 pushes up the push rod 400 during the horizontal movement, and the push rod 400 then pushes up the connecting rod 13, and the chip fixing device The chip fixture is then removed and the spring 200 is released to lift the trigger block 91. The trigger block 91 drives the pressure block 9 to move upward through the trigger rod 92. The spring 200 is restored and pushes the slide plate 8 toward the pressure block 9. The push block 81 is then returned to its original position. The push rod 400 is lowered by gravity. In this way, the chip test seat can quickly and easily remove the chip fixture, greatly shortening the time for replacing the chip fixture.
