Description

Technical Field

[0001] The utility model relates to the field of chip manufacturing, in particular to a quality testing Peel fixture. Background Art

[0002] Chips are usually made of single-crystal silicon wafers. After the wafer is cut, it forms multiple small grains, namely IC chips. Usually, multiple IC chips are fixed on the material strip in sequence using a substrate. The tension of each IC chip fixed on the material strip has a controlled value, and a fixture must be used to perform peel measurement and record the data.

[0003] After searching Chinese patents, the publication number is: CN206650061U, a chip clamp and a fixture, the clamp cannot replace the clamping head, the clamping head of the clamp is integrated with the clamping rod, and it is difficult to replace according to actual needs. If you need to replace the clamping head of a different shape, you need to replace the entire clamp, which increases the cost of use, reduces practicality and applicability, is inconvenient to use, and cannot adjust the clamping force. The clamping force of the clamp is determined by the spring, and the elastic force of the spring of the clamp is fixed, resulting in a fixed clamping force. During use, if the clamping force is small, the chip is easy to fall off. If the clamping force is too large, it is easy to damage the chip, and it is more laborious to clamp, which reduces practicality and is inconvenient to use. In order to solve the above problems, we propose a quality test Peel fixture. Utility Model Content

[0004] The utility model aims to provide a quality testing Peel clamp, which has the advantages of being able to replace the clamping head and adjust the clamping force.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: a quality testing Peel clamp, comprising a first clamping rod, a second clamping rod hinged to the top of the first clamping rod, a mounting rod slidingly sleeved on the inner walls of the first clamping rod and the second clamping rod, a clamping head bolted to one end of the mounting rod, a fixing pin passing through the inner walls of the first clamping rod and the second clamping rod, and the fixing pin and the inner wall of the mounting rod passing through, a limiting head slidingly sleeved on the inner wall of the fixing pin, a first spring arranged between the limiting heads, a limiting groove being provided on the inner walls of the first clamping rod and the second clamping rod, and the limiting groove being clamped to the limiting head.

[0006] By adopting the above technical solution, the limiting head is disengaged from the limiting groove by moving the fixing pin, and then the fixing pin is pulled out, the clamping head is removed, the mounting rod on the new clamping head is inserted into the first clamping rod or the second clamping rod, and the fixing pin is inserted. The limiting head is engaged with the limiting groove under the action of the first spring and fixed, thereby achieving the purpose of replacing the clamping head, reducing the cost of use, and improving practicality and applicability.

[0007] The utility model is further configured as follows: a threaded rod is bolted to the top of the first clamping rod, a fixed rod is bolted to the bottom of the second clamping rod, an adjustment block is threadedly connected to the surface of the threaded rod, a second spring is sleeved between the surface of the threaded rod and the fixed rod, and the second spring is located on the top of the adjustment block.

[0008] By adopting the above technical solution, the adjusting block is rotated to move longitudinally along the threaded rod. The adjusting block rises and squeezes the second spring, thereby increasing the elastic force of the second spring and thus increasing the clamping force. The adjusting block is rotated in the opposite direction to make it descend and extend the second spring. The extension of the second spring reduces the elastic force of the second spring and thus reduces the clamping force, thereby achieving the purpose of adjusting the clamping force, ensuring the stability of the clamping and improving practicality.

[0009] The utility model is further configured as follows: a rubber pad is bonded to the surface of the clamping head.

[0010] By adopting the above technical solution and providing a rubber pad, damage to the chip can be prevented.

[0011] The utility model is further configured as follows: the surface of the adjusting block is provided with anti-slip grooves.

[0012] By adopting the above technical solution and providing the anti-slip grooves, the adjustment block is easy to rotate and the operation is convenient.

[0013] The utility model is further configured as follows: one end of the limit head is in an arc shape.

[0014] By adopting the above technical solution, one end of the limit head is arranged in an arc shape, which facilitates engagement and disengagement with the limit groove and is convenient for use.

[0015] The utility model is further configured as follows: the shape of the clamping head is wedge-shaped.

[0016] By adopting the above technical solution, the clamping head is set to be wedge-shaped, which facilitates clamping.

[0017] The utility model is further configured as follows: anti-slip sleeves are fixedly sleeved on the surfaces of the first clamping rod and the second clamping rod.

[0018] By adopting the above technical solution, a protective cover is provided to prevent hand slipping and facilitate operation.

[0019] The present invention is further configured such that the length of the first clamping rod is greater than the length of the second clamping rod.

[0020] By adopting the above technical solution, the length of the first clamping rod is set to be greater than the length of the second clamping rod, which is convenient for use.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The utility model disengages the limit head from the limit groove by moving the fixing pin, then pulls out the fixing pin, removes the clamping head, inserts the mounting rod on the new clamping head into the first clamping rod or the second clamping rod, and inserts the fixing pin. The limit head engages with the limit groove under the action of the first spring and is fixed, thereby achieving the purpose of replacing the clamping head, reducing the use cost and improving practicality and applicability.

[0023] 2. The utility model rotates the adjusting block to move the adjusting block longitudinally along the threaded rod. The adjusting block rises and squeezes the second spring, thereby increasing the elastic force of the second spring and thus increasing the clamping force. The adjusting block is rotated in the opposite direction to make it descend, thereby extending the second spring. The extension of the second spring reduces the elastic force of the second spring and thus reduces the clamping force, thereby achieving the purpose of adjusting the clamping force, ensuring the stability of the clamping and improving practicality.
