Referring to fig. 1 and 2, a represents a pipeline, B represents a carrier on the pipeline, C represents a workpiece, and an arrow represents a moving direction of the carrier B driven by the pipeline. The application provides blanking equipment which is used for blanking a workpiece C on a production line A and comprises a material taking mechanism 1, a transfer platform 2 and a material discharging mechanism 3. The material taking mechanism 1 is arranged above the assembly line A and is used for transferring the workpiece C conveyed by the assembly line A, namely, the workpiece C placed on the carrier B is taken out and transferred to the transfer platform 2, the workpiece C is placed on the transfer platform 2, and the transfer of the workpiece C from the carrier B to the transfer platform 2 is completed.

The transfer platform 2 is arranged on one side of the material taking mechanism 1, and the transfer platform 2 can be used for placing and positioning the workpiece C transferred by the material taking mechanism 1 from the assembly line A.

The discharging mechanism 3 is arranged close to the transfer platform 2, the discharging mechanism 3 is used for transferring the workpiece C on the transfer platform 2, and the discharging mechanism 3 respectively places the qualified workpiece C and the unqualified workpiece C in different material boxes. The carrier B is provided with a qualified workpiece C and an unqualified workpiece C, and the qualified workpiece C and the unqualified workpiece C are required to be stored independently; the material taking mechanism 1 takes all the workpieces C (including qualified workpieces C and unqualified workpieces C) out of the carrier B, and the workpieces C can be taken out in batches or all the workpieces C can be taken out at one time; all the workpieces C are firstly placed on the transfer platform 2, and the qualified workpieces C and unqualified workpieces C can be placed on the transfer platform 2 at the same time. The qualified and unqualified workpieces C and C are determined by the previous detection steps, the positions of the qualified and unqualified workpieces C on the carrier B are constant, and the qualified and unqualified conditions of the workpieces C are determined by the detection results. When the discharging mechanism 3 takes out the workpiece C from the transferring platform 2, the workpiece C is grasped and transferred according to the qualification and disqualification conditions of the workpiece C, the qualified workpiece C and the disqualification workpiece C are stored in different material boxes, namely, the qualified workpiece C is placed in one material box, and the disqualification workpiece C is placed in the other material box. The material box for placing the qualified workpieces C and the material box for placing the unqualified workpieces C can adopt the same structure or different structures, and the specific implementation modes are included in the protection scope of the application.

According to the application, through the mutual matching of the material taking mechanism 1, the transfer platform 2 and the material discharging mechanism 3, the qualified workpieces C and the unqualified workpieces C are stored independently, and the sorting and the arrangement are convenient.
