After electrical performance verification, the chip is then removed from the connector socket. However, current technologies often employ manual insertion and removal, which presents the following problems:
[0003] (1) The operation is difficult and requires a high level of skill from the operator, which can easily lead to the chip pins bending or breaking.

[0005] (3) Manual operation is inefficient and cannot meet the needs of large-scale testing;
[0006] (4) Relying on the operator's experience, novice operation can easily lead to chip or socket failure.

[0028] 4. Chip. Detailed Implementation
[0029] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.
[0030] like Figure 1 As shown, this application proposes a chip disassembly fixture, which includes a clamping member 1, a support member 2, and a rotary drive member 3. The clamping member 1 is used to clamp the chip 4 inserted into the connector socket. The support member 2 is used to stabilize the clamping state of the clamping member 1 and provide support force for the rotary drive member 3. The rotary drive member 3 rotates to drive the clamping member 1 and the clamped chip to move away from the socket, so as to realize the disassembly and separation between the chip and the socket. The separation process is simple.
[0031] like Figure 1 and 2 As shown, the clamping member 1 includes a substrate 11, with clamping plates 12 rotatably connected to opposite sides of the substrate 11. The two clamping plates 12 correspond to form a clamping area 120. The two sets of clamping plates 12 cooperate to clamp the two sides of the chip 4, thus clamping the chip 4 in the clamping area 120. When the two sets of clamping plates 12 are in the open state, the clamping member 1 can be moved until the chip is placed in the clamping area 120. Then, the two sets of clamping plates 12 are closed, and the chip is clamped. By limiting the position of the two sets of clamping plates 12, the chip 4 can be locked in the clamping area 120.
[0032] like Figure 1 and 2 As shown, the clamping plate 12 has a support portion 121 at the end away from the substrate 11, which supports the bottom of the chip. When the chip 4 is locked in the clamping area 120, the clamping member 1 moves upward, and the support portion 121 lifts the chip and moves upward synchronously. Preferably, the horizontal extension length of the support portion 121 is adapted to the length of the chip to apply a uniform supporting force to both sides of the chip, ensuring that the four corners of the chip are simultaneously released from the socket, improving clamping stability and preventing damage to the chip pins. Preferably, in one embodiment, the support portion 121 can be configured as a step extending horizontally in the direction of the clamping area 120, and when the clamping plate 12 is in the clamping state, the step supports the bottom of the chip.
[0033] like Figure 1 and 2 As shown, preferably, in this embodiment, one end of the clamping plate 12 is hinged to the base plate 11 via a pin 13, and the clamping plate 12 can rotate around the pin 13 to achieve the opening and closing states of the clamping plate 12.
[0034] like Figure 1-3 As shown, the support member 2 includes an abutment portion 21 and limiting portions 22 arranged parallel to each other on opposite sides of the abutment portion 21. The limiting portions 22 are used to limit the rotation range of the clamping plate 12 and support the abutment portion 21 mounted above the clamping member 1 so that the abutment portion 21 provides support force to the rotating drive member 3. When the two sets of clamping plates 12 are in the closed clamping state, the lower end of the limiting portion 22 contacts the chip connector. The two sets of parallel limiting portions 22 are located on the outside of the clamping plate 12 and are connected to the clamping plate 12 to limit the rotation of the corresponding clamping plate 12, thereby locking the clamping state of the clamping member 1 and ensuring that the clamping state is maintained during the upward displacement of the clamping member 1. The abutment portion 21 has a through hole 211 that is opened vertically through the center. When the support member 2 is mounted above the clamping member 1, the through hole 211 and the threaded hole 111 are concentrically arranged.
[0035] like Figure 1-4 As shown, the rotary drive 3 includes a frustum 31, which includes a first end 311 and a second end 312 that are axially opposite each other. A cylindrical part 32 is coaxially provided on one side of the first end 311. The cylindrical part 32 can pass through the through hole 211 and be threaded into the threaded hole 111. Figure 4 (The external thread structure is not shown in the figure). A rotating part 33 is provided on one side of the second end 312. By rotating the rotating part 33, the rotating drive 3 can be driven to rotate in a circle.
[0036] like Figure 1-4 As shown, preferably, in this embodiment, the diameter of the second end cross-section of the frustum 31 is larger than the diameter of the first end cross-section, and the diameter of the second end cross-section is larger than the diameter of the through hole, so that there is at least one position on the frustum 31 where its cross-sectional diameter is equal to the diameter of the through hole. When the frustum 31 is correspondingly engaged in the through hole 211, the support member 2 provides an upward support force to the frustum 31 to limit the axial displacement of the rotary drive member 3. When the rotary drive member 3 rotates circumferentially, it can drive the clamping member 1, which has a threaded engagement with its cylindrical portion 32, to move axially. Through the threaded transmission, the clamping member 1 is driven to rise slowly, and the clamping plate 12 simultaneously pulls the chip until it is completely detached from the adapter socket, converting the rotational motion into a vertical pull-out force, effectively saving manpower, ensuring the controllability of the force application process, and improving the stability of the chip detachment process.
[0037] Preferably, the cylindrical part 32, the frustum part 31 and the rotating part 33 are integrally formed by machining, which simplifies the manufacturing process and increases the structural strength.
[0038] like Figure 1-4 As shown, preferably, the rotating part 33 has a horizontally opened mounting hole 331, into which a push rod can be inserted. The push rod is used to drive the rotating drive 3 to rotate in a circular motion, making the rotation process of the rotating drive 3 more effortless.
[0039] Working principle:
[0040] With the clamping plate 12 in the open state, the chip 4 inserted on the connector mounting base is placed in the clamping area 120. The clamping plate 12 is then closed, and the chip is clamped between the two sets of clamping plates 12. The support member 2 is placed above the clamping member 1, and the lower end of the limiting part 22 of the support member 2 is placed on the chip connector. The limiting part 22 restricts the two sides of the clamping plate 12, so that the clamping member 1 maintains the state of clamping the chip. The cylindrical part 32 of the rotary drive member 3 is inserted into the threaded hole 111 through the through hole 211. By rotating the rotating part 33, the rotary drive member 3 rotates in a circular motion. The cylindrical part 32 is threaded into the threaded hole 111, and the rotary drive member 3 moves downward until the frustum part 31 of the rotary drive member 3 is stuck in the through hole 211. The abutting part 21 of the support member 2 abuts against the frustum part 31. The support member 2 provides an upward supporting force to the rotary drive member 3, so that the rotary drive member 3 no longer moves downward and its position remains stable in the horizontal direction. Continue rotating the rotating part 33, and the entire rotating drive 3 continues to rotate in a circular motion. At this time, the clamping part 1, which is threaded with the cylindrical part 32, moves upward in the opposite direction. The clamping part 1 drives the clamped chip to move upward synchronously until the chip is disengaged from the connector socket. After the chip insertion and removal are completed, the rotating drive 3 is rotated in the opposite direction to restore the fixture to its initial position so that the chip can be removed.
[0041] This application converts the rotational torque applied by the operator into an axial linear force through mechanical transmission, ensuring the controllability of the force application process and effectively avoiding the risk of device damage caused by uneven force in traditional manual operations. The rotational action is simple, effectively saving manpower and improving work efficiency. It is particularly suitable for the non-destructive disassembly requirements of high-density pin integrated circuits in the testing process, significantly improving chip repair efficiency and test equipment reuse rate, and solving the chip damage problem caused by traditional manual operations.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
