The first pressing block 331 and the second pressing block 332 are made of conductive metal, and are matched to press the outer diameter of the battery cell 06, so as to detect whether the outer diameter of the battery cell 06 is short-circuited.
In this embodiment, the housing detection mechanism 03 is mainly used for short-circuit detection of the outer diameter of the battery cell 06 in the negative electrode outer packaging process.
By the connection of the above structures, the operation steps of the first or second embodiment can be optimized as: the position of the negative electrode clamping mechanism is set in advance by the third control valve and the fourth control valve so that the negative electrode clamping mechanism does not touch the battery cell 06 when the driving belt drives to reach the detection position. The battery cell 06 is placed in the feeding mechanism 05 after being wound, namely placed on a groove of the conveying plate, the feeding mechanism 05 conveys the battery cell 06 to a specified short circuit detection position, then the driving motor drives the driving belt through the pulley, the driving belt rotates anticlockwise, and the lower side driving belt drives the positive electrode detection mechanism 01 to slide rightwards on the first slideway 011 through the first connecting block 012. After the positive electrode detection mechanism 01 reaches a specified detection position, the motor drives the positive electrode detection mechanism 01, and the first control air valve 133 of the first clamping claw drives the upper clamping piece 131 to be matched with the lower clamping piece 132 to clamp the first tab 61 of the battery cell 06 so as to detect whether the positive electrode shell of the battery cell 06 is short-circuited. The control cylinder 32 and the positive electrode detection mechanism 01 synchronously move, and the control cylinder 32 drives the pressing mechanism to move downwards until the first pressing block 331 and the second pressing block 332 are matched to press the battery cell 06, and short circuit detection is carried out on the outer diameter of the battery cell 06 in the negative electrode outsourcing process.
