[0036] The applicant analyzes the fact that the existing material filling device is prone to material damage and finds that batteries are generally filled with magnetic materials. When the existing industrial material filling production line uses a mechanical clamp to clamp magnetic materials, the magnetic material is prone to damage due to the following reasons. The magnetic material is relatively soft, and the mechanical clamp has a large force, which is easy to crush the magnetic material. The mechanical clamp has a small force, and the magnetic material is easy to be damaged due to falling during movement. Therefore, the problem of magnetic material damage often occurs.

[0037] To this end, the applicant proposes a material filling device and a material filling teaching platform. The device conveys materials and containers separately via two conveyor belts, and the materials are picked up by suction cups. The suction cups integrate electromagnets. When filling magnetic materials, the strength of the electromagnet's attraction to the magnetic material can be controlled by adjusting the current flowing through it. After the suction cup releases the material, the electromagnetic force counteracts some of the gravity, allowing the magnetic material to fall slowly, thus protecting it. The following is one embodiment of the material filling device and material filling teaching platform of this invention:

The alarm lamp 8 can display three states of red, yellow and green, and the three states correspond to three different states of device failure, device maintenance adjustment and normal working respectively, so as to help a user to quickly judge the working state of the device.

[0053] Compared with the prior art, the material filling device provided by the application only needs to pass current to the electromagnet to make the magnetic material slowly fall when filling the magnetic material, a simple control logic is added to achieve the purpose of protecting the magnetic material, and only one electromagnet needs to be integrated into a conventional material suction disc, so that the cost is not high.

[0054] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the application.
