Magnetic blanking device

Technical Field

The invention relates to a material handling technology in assembly line operation, in particular to a magnetic blanking device.

Background

During the in-line manufacturing process, there is a step of unloading the sheet products and/or parts from the conveyor belt and stacking the sheet products and/or parts on the material pallet.

In the traditional technology, a belt is adopted for transmission, and then the stacking mode is manually arranged, so that the manual mode consumes time and labor. With the development of industrialization, a mode that a stacker receives materials and arranges the materials appears later, but although the stacker solves the manual problem, the receiving and arranging stacking process is slow, and the stacker is not suitable for assembly line operation.

Then, the structure that the sucker grippers are carried by the mechanical arm is adopted in most of the prior art, and the sucker grippers are carried by the mechanical arm to move the sheet products and/or parts on the conveying belt to the material pallet. In such a structure, although the robot arm has good stability in handling, the robot arm needs to return for a certain period of time after handling each time, so that the robot arm cannot realize continuous handling of the sheet-like products and/or parts.

Therefore, in order to solve the problem of the line work, it is necessary to design a device capable of continuously carrying and stacking in a short time.
