Battery piece front side and back side detecting device and method

Abstract

The invention discloses a battery piece front side and back side detecting device and method. The detection device comprises conveying mechanisms, a front side detector and a back side detector, and further comprises a rotating table mechanism; the rotating table mechanism comprises a base and a rotating table rotationally arranged on the base; the rotating table mechanism is sequentially providedwith a feeding station, a detecting station and a discharging station in the circumferential direction of the rotating table mechanism; the rotating table is provided with a plurality of vacuum adsorbing mechanisms used for adsorbing battery pieces; the vacuum adsorbing mechanisms are arranged at intervals in the circumferential direction of rotation of the rotating table; the conveying mechanisms comprise a feeding conveying mechanism and a discharging conveying mechanism; the feeding conveying mechanism extends to the feeding station position of the rotating table mechanism; and the discharging conveying mechanism extends to the discharging station position of the rotating table mechanism. Due to the battery piece front side and back side detecting device, the detecting efficiency can be improved, and meanwhile frequent piece falling or breaking can also be reduced.

Description

technical field [0001] The invention relates to the technical field of cell manufacturing, in particular to a detection device and method for the front and back of a cell. Background technique [0002] Existing manufacturers use a combination of conveying belt and vacuum adsorption device when testing the front and back of the battery sheet, specifically: the battery sheet is conveyed by the belt in the front section of the detection section to the loading station and then lifted by the cylinder, and the vacuum adsorption plate will hold the battery sheet. It is sucked onto the conveyor belt of the adsorption section, and the conveyor belt of the adsorption section transmits the cells to the detection station. The optical detector takes pictures of the back of the cells and detects them. Gravity drop, this detection method is inefficient, and it is easy to cause the vacuum adsorption to be too small or too large, resulting in the phenomenon of falling pieces and fragments, r...
