[0100] In the embodiment, after the Z-shaped clamping arm 5292 is controlled by the telescopic air cylinder (not shown) to be displaced downward and inserted into the clamping hole, the two carrying blocks 5291 are adjusted to be displaced in opposite directions, so that the bottom of the Z-shaped clamping arm 5292 is inserted at the bottom of the top plate of the bin body 430, thereby realizing the clamping effect of the bin body 430. Then, the Z-shaped clamping arm 5292 is controlled by the telescopic air cylinder (not shown) to be displaced upward, the bin body 430 is lifted, and the bin body 430 is horizontally displaced by the carrying motor 523, so that the bin body 430 is transferred to the aggregate workstations 50 of other columns.

[0101] In implementation, screw holes can be formed at the top of the sliding groove, the carrying block 5291, and the Z-shaped clamping arm 5292, and a screw rod is simultaneously inserted through the three screw holes to limit the carrying seat 529, the carrying block 5291, and the Z-shaped clamping arm 5292. Of course, other limiting methods can also be selected according to actual conditions, such as the magnetic connection between the carrying block 5291 and the sliding groove, or the sliding of the carrying block 5291 in the sliding groove through the cooperation of the ball screw. As long as the Z-shaped clamping arm 5292 can be inserted into the clamping hole at the top of the bin body 430, and the bottom of the Z-shaped clamping arm 5292 has abutted against the bottom of the top plate of the bin body 430, it is ensured that the Z-shaped clamping arm cannot be horizontally displaced under non-accidental conditions.

[0102] In this way, the carrying mechanism can make the different columns of the material collecting bins in the material collecting area transfer, and the third moving module is matched to adjust the position of the positioning frame on the vertical plate, so that the working efficiency can be further improved.

[0103] The above is only one specific embodiment of the present application, and any improvement made on the basis of the concept of the present application is considered to be within the protection scope of the present application.
