Thus, the scissors feet, which are flexible enough, open at the deployment slot 5525. Generally, the rotation axis of the inner scissors is offset from the center of gravity of the inner scissors, and the inner scissors are opened by gravity when the scissor legs reach the position of the deployment slot 5525.

Specifically, the deployment testing mechanism 556 may also include a deployment drive 5564, the deployment drive 5564 to assist in the scissor foot opening. Specifically, deployment driver 5564 may be a trachea that can blow air against the scissor feet located at deployment slot 5525, assisting the scissor feet in opening.

In this embodiment, the screening mechanism 558 includes a limiting groove 5527 opened at the bottom of the rail groove 5524 of the testing rail 552 and a notch 5528 opened on the testing rail 552, the notch 5528 is located at one side of the limiting groove 5527, the width of the limiting groove 5527 is smaller than the width of the expanding groove 5525 and smaller than the width of the inner scissors, the width of the limiting groove 5527 is larger than the thickness T1 of the inner scissors, and the limiting groove 5527 is communicated with the expanding groove 5525. Thus, referring to fig. 24, the scissors with qualified flexibility are opened by rotating 90 ° at the position of the expansion slot 5525, the outer scissors and the inner scissors of the opened scissors are perpendicular to each other, the scissors with unqualified flexibility are not opened at the position of the expansion slot 5525, and the outer scissors of the unopened scissors are parallel to the inner scissors. When the scissor legs with qualified flexibility flow to the screening mechanism 558, the opened inner scissors extend into the limiting groove 5527, and the limiting groove 5527 can limit the inner scissors, so that the whole scissor legs are prevented from falling from the notch 1528; when the scissors feet with unqualified flexibility flow to the screening mechanism 558, the inner scissors and the outer scissors are located on the rail groove 5524 and cannot extend into the limiting groove 5527 (see the scissors feet 100b in fig. 10), the inner scissors are not limited by the limiting groove 1527, so that the unqualified scissors feet fall out of the test rail 552 from the notch 5528, the unqualified scissors feet are separated, and the unassembled outer scissors also fall out of the notch 5528 due to the fact that the inner scissors do not extend into the limiting groove 5527.

Specifically, the connection between the limiting groove 5527 and the expansion groove 5525 is a bevel transition, i.e., a bell-mouth transition. Thus, the inner scissors can be prevented from being stuck at the connection between the limit groove 5527 and the expansion groove 5525.

Specifically, the sifting mechanism 558 further includes a flexible sifting block 5582, and the flexible sifting block 5582 is disposed at an end of the gap 5528 away from the deployment slot 5525. The unqualified scissor legs can be prevented from flowing forwards through the flexibility screening block 5582, and the unqualified scissor legs can be ensured to fall from the notch 5528.

Specifically, the screening mechanism 558 further includes an auxiliary screening drive 5584, the auxiliary screening drive 5584 being configured to assist the defective scissor foot to fall out of the notch 5528. Specifically, the auxiliary screen drive 5584 may be an air tube that blows off an unacceptable scissor foot located on the track slot 5524 toward the notch 5528.

In this embodiment, the flexibility detection mechanism 55 further includes a bin 560 with an unqualified flexibility, and the bin 560 with an unqualified flexibility is butted with the notch 5528 and is located below the notch 5528 to collect the unqualified flexibility product and the unassembled outer scissors.

In this embodiment, the flexibility detection mechanism 55 further includes a flexibility qualified bin 562, and the flexibility qualified bin 562 is disposed below the flexibility screening block 5582 to collect the flexibility qualified products.

In this embodiment, the inspection device further includes a product flow drive 59 for assisting in driving the flow of product (i.e., scissor-feet) over the test track 552. Specifically, the product flow drive 59 may be an air tube that pushes the product to flow on the test track 552 by blowing air.

Utilize the utility model discloses detection device, can detect out and make it drop single scissors feed bin 538 through the interior scissors of feed screening mechanism 53 with unassembled earlier, then the scissors foot flows on test track 552, select the qualified scissors foot of plane degree through plane degree screening piece 554 earlier, make the qualified scissors foot of plane degree pass the below of plane degree screening piece 554, reach the position of launching accredited testing organization 556, make the qualified scissors foot of flexibility degree launch accredited testing organization 556 and locate to open in accredited testing organization 556, reachs screening mechanism 558 again, screening mechanism 558 makes in the unqualified scissors foot of flexibility degree and the unqualified feed bin 560 of flexibility degree drop, and the qualified scissors foot of flexibility degree drops in the qualified feed bin 562 of flexibility degree after passing through screening mechanism 558.

The utility model discloses scissors foot equipment detection device can assemble automatically and detect the scissors foot, need not manual operation, can improve equipment and detection efficiency greatly, improves the product yield to can prevent the false retrieval, improve the accuracy that detects, improve the product percent of pass of final shipment, improve customer satisfaction.
