The material taking driving piece drives the material taking head 31 and the material taking insert block 32 to move to the blanking piece 34, the material taking insert block 32 is continuously driven to move downwards, the positioning part 321 on the material taking insert block 32 is connected with the opposite part 341, then the material taking driving piece drives the material taking head 31 to rotate, the material taking insert block 32 in the material taking cavity 311 is driven to rotate to the first station from the second station, then the material taking driving piece drives the material taking head 31 and the material taking insert block 32 to move upwards, and at the moment, the frame body in the material taking cavity 311 falls to the blanking piece 34 from the first station.

The positioning portion 321 is a non-rotating hole formed in the material taking insert block 32, and the aligning portion 341 is a non-rotating boss formed on the blanking member 34 and matched with the aligning portion 341. Form non-gyration cooperation through non-gyration hole and non-gyration boss, will get the rotation of expecting the inserted block 32 fixed, get stub bar 31 through the drive and rotate for the framework rotates to first station on, and then falls down by getting in the material chamber 311.

in this embodiment, the positioning portion 321 is two circular holes formed in the material taking insert block 32, and the positioning portion 341 is two bosses formed on the material discharging member 34.

In another embodiment, a blanking driving member is disposed below the blanking member 34, and the blanking driving member drives the blanking member 34 to move towards and away from the material taking head 31, so that the positioning portion 341 on the blanking member 34 is engaged with the positioning portion 321 of the material taking insert 32, thereby reducing the driving track of the material taking driving member.

In this embodiment, the material taking mechanism 3 further includes a material blowing member, the material discharging groove 342 is formed in the material discharging member 34, and the material blowing member blows the workpiece on the material discharging member 34 into the material discharging groove 342. The frame body falling on the alignment piece of the blanking piece 34 needs to be taken down in time, the frame body for next blanking is avoided, and wind towards the lower trough 342 is provided through the blowing piece, so that the frame moves towards the lower trough 342 and falls into the lower trough 342 to realize complete blanking.

Get the material piece and be the platform form, get and be equipped with the recess on the material piece, during the recess was located to counterpoint portion 341, the feed chute 342 was located in the recess, is equipped with air outlet 343 on the lateral wall of recess simultaneously, blows the material piece and blows the framework to the feed chute 342 in through this air outlet 343 air-out, realizes the unloading of frame.
