Claim 0:
1. A tab inspection method, wherein a tab protrudes from an end face of an electrode plate along a first direction, and the method comprises:
determining a first start position of the tab in a second direction of the electrode plate according to a first trigger manner, wherein the second direction is perpendicular to the first direction;
determining a second start position of the tab in the second direction of the electrode plate according to a second trigger manner; and
determining, according to a distance between the second start position and the first start position, whether a position of the tab on the electrode plate deviates;
wherein the first trigger manner is a manner for determining the position of the tab based on a change of a height of the electrode plate in the first direction, and the second trigger manner is a manner for determining the position of the tab based on a preset position of the tab on the electrode plate, and
wherein the method is performed by a tab inspection apparatus, the apparatus is connected to a sensor, the sensor comprises an emitting end and a receiving end, the emitting end and the receiving end are disposed opposite to each other on two sides of the electrode plate, so that the electrode plate moves in the second direction between the emitting end and the receiving end, the emitting end is configured to emit light, and the receiving end is configured to collect optical signals when the electrode plate moves to multiple different positions, to obtain multiple pieces of inspection data of the electrode plate at the different positions.
