The working principle of the clamp assembly provided by the invention is as follows:

(1) feeding process (as shown in fig. 3 to 5): the feeding block 122 is driven by the feeding driving member 121 to move to a side of the material loading frame 11 facing away from the clamp 2, and then the feeding block 122 is driven by the feeding driving member 121 to move toward a direction close to the clamp 2, so that the second end 1222 can abut against a side edge of the blank 200 to be processed facing away from the clamp 2, and the first end 1221 of the feeding block 122 abuts against the feeding bracket 123 (at this time, the feeding module 12 is in a feeding initial position). Then, the feeding block 122 is driven by the feeding driving member 121 to move in a direction close to the clamp 2, so as to push the blank 200 to be processed on the carrier 11, which is located at the lowest position, to move in a direction close to the clamp 2, thereby realizing feeding. During the process of moving the feeding block 122 to the side of the carrier 11 facing away from the fixture 2, if the feeding block 122 moves below the carrier 11, the second end 1222 deflects and presses down the blank 200 on the carrier 11, as shown in fig. 3.

(2) Material receiving process (as shown in fig. 9 to fig. 11): the material receiving driving member 321 drives the material receiving block 322 to move to a side of the blank 200 on the fixture 2 opposite to the fixture 2, and then the material receiving driving member 321 drives the material receiving block 322 to move towards a direction close to the blank 200 on the fixture 2, so that the fourth end 3222 of the material receiving block 322 can abut against a side edge of the blank 200 opposite to the material receiving frame 31, and the third end 3221 of the material receiving block 322 abuts against the material receiving limiting member 3232 of the material receiving support 323 (at this time, the material receiving module 32 is at the material receiving initial position). Then, the material collecting driving member 321 drives the material collecting block 322 to move towards the direction close to the clamp 2, so as to push the blank 200 to be processed at the lowest position on the material loading frame 11 to move towards the direction close to the material receiving frame 31, until the blank 200 falls into the material receiving frame 31 to realize material collection. In the process of moving the slug 322 to the side of the blank 200 on the fixture 2 opposite to the fixture 2, if the slug 322 moves above the blank 200, as shown in fig. 9, the fourth end 3222 will be deflected by the blank 200.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
