Tool battery pole piece

Can surface multiple types defects of lithium battery pole piece be detected?

The experimental results show that the proposed method in this paper can effectively detect surface multiple types defects of lithium battery pole piece, and the average recognition rate of defects reaches 98.3%, which is an effective and feasible automatic defect detection and identification method.

What is a rotor pole piece?

The Rotor Pole Piece A rotor, as its name implies, is a component that rotates and produces mechanical output power. Component 2, Fig. 4.6, is a 50-tooth rotor soft iron pole piece made up from 20 pieces of 0.5 mm thickness laminated, magnetically permeable, Silicon-iron, SiFe, sheets that are riveted tightly together (rivets not shown).

How to sort retired batteries?

Retired batteries have undergone a long service and disassembly process, and the cell appearance may be mechanically deformed or damaged. This undoubtedly increases the hidden danger of battery safety. Therefore, the first step in the sorting of retired batteries is shape screening .

How do you secure a forged pole rotor?

Solid forged pole-shoes are secured by high tensile strength bolts after the coils have been put on. For the lower peripheral speeds associated with multipole rotors, separate laminated pole pieces may be secured by dovetails or T heads in slots in the square or hexagonal middle portion of the forged shaft.

How are the pole pieces oriented during the force fitting process?

During the force fitting process, the pole pieces are precisely oriented in a radial direction such that the pole pieces are oriented tooth, gap, tooth, gap or gap, tooth, gap, tooth when viewed in the axial direction as shown in Fig. 4.12. This arrangement of the teeth and gaps will be explained shortly.

Why is it important to protect the battery during the stamping process?

As the outer package of the battery, it is necessary to avoid wrinkles, cracks, pinholes and other defects of the aluminum-plastic film during the stamping process, otherwise the battery may have safety problems such as liquid leakage, short circuit and expansion .
