[0026] like Figures 1 to 5 As shown, the chip strength measurement placement fixture of the utility model includes a first adjustment seat 100, a second adjustment seat 200 and a placement seat 300. The placement seat 300 is used to place the chip to be measured. The first adjustment seat 100 is used to adjust the height of the placement seat 300, and the second adjustment seat 200 is used to adjust the placement seat 300 to move along the first direction, so as to realize the measurement of the chips on the placement seat 300 one by one.
[0027] The first adjustment seat 100 includes a base, a top block, a connecting block connected between the base and the top block, and also includes a first screw rod 101 rotatably installed between the base and the top block, that is, the first screw rod 101 extends along the height direction, and the first screw rod 101 is rotatably connected to the base and the top block through a bearing. The second adjustment seat 200 is threadedly connected to the first screw rod 101, and the second adjustment seat 200 moves up and down along the first screw rod 101 by rotating the first screw rod 101.
[0028] In this embodiment, a accommodating cavity is provided at the bottom of the base, the bottom end of the first screw 101 passes through the base and extends into the accommodating cavity, and a first bevel gear 101a is fixed to the bottom end of the first screw, and a second bevel gear 103 meshing with the first bevel gear 101a is rotatably installed on the base, and the second bevel gear 103 is connected to the base by rotating a rotating rod installed on the base, and the second bevel gear 103 is driven to rotate by rotating the rotating rod, and the rotation of the second bevel gear 103 drives the first bevel gear 101a meshing with it to rotate, thereby driving the first screw 101 to rotate so that the second adjustment seat 200 moves up and down along the first screw 101.
[0029] Furthermore, the first adjustment seat 100 is also provided with a first guide rod 102 extending in the height direction, and the second adjustment seat 200 is sleeved on the first guide rod 102.

Preferably, two groups of the first guide rods 102 are provided.
[0030] The second adjustment seat 200 extends along a first direction which is perpendicular to the height direction, and includes a connecting portion connected to the first adjustment seat 200 and an adjusting portion for mounting the placement seat 300, wherein the connecting portion is provided with a threaded hole and a through hole, the first screw rod 101 is connected to the threaded hole, and the first guide rod 102 passes through the through hole.

[0032] Furthermore, the second adjustment seat 200 also includes a second guide rod 202 installed in the adjustment groove, and the second guide rod 202 extends along the first direction, that is, it is arranged in parallel with the second screw 201, and the placement seat 300 is sleeved on the second guide rod 202. The second guide rod 202 first limits the placement seat 300 to rotate synchronously with the second screw 201 during the rotation of the second screw 201, causing the placement seat 300 to be offset; secondly, the second guide rod 202 is used to guide the placement seat 300 to move along the first direction to ensure the stability of the placement seat 300 during the movement.
[0033] Preferably, two groups of the second guide rods 202 are provided, and the second screw rod 201 is located between the two groups of the second guide rods 202 .
[0034] The placement seat 300 has a plurality of placement grooves 301 on its top, and the plurality of placement grooves 301 are arranged at intervals along the first direction. The chips to be measured are placed in the placement grooves 301 one by one, and the chips in the placement grooves 301 are moved in the height direction by rotating the first screw rod 101, and the chips in the placement grooves 301 are moved in the first direction by rotating the second screw rod, thereby pushing the chips to the pressure head position one by one for measurement.
[0035] Further, the placement seat 300 includes two placement blocks 303 threadedly connected to the moving part 302 on the second screw rod 201 and spaced apart at the top of the moving part 302 along a second direction, the second direction is perpendicular to the first direction, and the placement groove 301 is opened at the top of the placement block 303. There is a gap between the two placement blocks 303, the placement grooves 301 on the two placement blocks 303 correspond to each other, and the two ends of the chip are respectively located in the placement grooves 301 of the two placement blocks 303.
[0036] The movable part 302 includes a receiving groove 302a opened at the top thereof, and a third screw 302b rotatably installed in the receiving groove 302a, wherein the third screw 302b extends along the second direction, and at least one of the placement blocks 303 is threadedly connected to the third screw 302b. Thus, by rotating the third screw 302b, the placement block 303 threadedly connected thereto can be moved along the third screw 302b, thereby adjusting the distance with another placement block 303 to adapt to chips of different sizes and improve versatility.
[0037] In this embodiment, the third screw rod 302b includes a first thread segment and a second thread segment, and the first thread segment and the second thread segment have opposite thread rotation directions, and the two placement blocks 303 are respectively threadedly connected to the first thread segment and the second thread segment. When the third screw rod 302b is rotated, the two placement blocks 303 can move toward each other or in opposite directions along the third screw rod 302b, so as to adapt to chips of different sizes. A support block for supporting the third screw rod 302b is also provided at the top of the accommodating groove 302a.
[0038] Furthermore, the moving part 302 also includes a third guide rod 302c installed in the accommodating groove 302a, and the third guide rod 302c extends along the second direction, that is, it is arranged in parallel with the third screw rod 302b.

The bottom of the moving part 302 is also provided with a connecting block 302d, and a threaded hole is opened on the connecting block 302d, and the third screw rod 302b is connected to the threaded hole.
[0039] Preferably, two groups of the third guide rods 302c are provided, and the third screw rod 302b is located between the two groups of the third guide rods 302c.
[0040] When the jig is used, firstly, the third screw rod 302b is rotated to adjust the distance between the two placement blocks 303 so that the distance between the two placement blocks 303 matches the length of the chip to be measured; then, the chips to be measured are placed into the placement slot 301 in sequence, and the chip farthest from the first adjustment seat 100 is defined as the first chip;
[0041] The second screw rod 201 is rotated to make the placement seat 300 and the chip thereon move synchronously along the first direction until the first chip is flush with the pressure head in the first direction, and then the first screw rod 101 is rotated to make the second adjustment seat 200, the placement seat 300 and the chip thereon descend synchronously until the first chip is placed on the pressure head, and then the machine is turned on to measure the strength of the first chip;
[0042] After the measurement is completed, the first screw 101 is rotated to make the second adjustment seat 200, the placement seat 300 and the chip thereon rise synchronously, and the chip after measurement returns to the placement groove 301, and then the second screw 201 is rotated to make the placement seat 300 and the chip thereon move synchronously along the first direction until the second chip is flush with the position of the pressure head in the first direction, and then the first screw 101 is rotated to place the second chip on the pressure head for measurement, and this process is repeated until the strength measurement of all chips is completed.
[0043] In summary, the utility model realizes the standardization and accuracy of chip placement through the first adjustment seat 100, the second adjustment seat 200 and the placement seat 300. Each placement position is located at the center of the pressure head, thereby improving measurement accuracy; reducing manual operations, avoiding chip bumps and damage, and reducing chip scrapping; and greatly improving chip strength measurement efficiency.
