Title:
Secondary battery manufacturing equipment
Document Type and Number:
Japanese Patent JP6365885
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing apparatus capable of suitably manufacturing a secondary battery, where winding deviation of a wound electrode body is suppressed.SOLUTION: A manufacturing apparatus 100 includes means for transporting the electrode sheets 12, 14 of positive and negative electrodes and separator sheets 16, 18 to a common winding shaft 130, and winding therearound, and detection means 102, 104 for measuring the positional deviation of the electrode sheets 12, 14. At least one of the detection means 102, 104 includes an optical detector having an optical axis change function, and illumination having a predetermined light emission range. The manufacturing apparatus 100 is configured so that the relationship of the predetermined angles α, α, βand β, when viewing the light emission range from a detection object point in the conveyance path or a direction perpendicular thereto, and the undulation angles θ, θof the detection object, i.e., the detection means 102, 104, satisfies α≥2θ, α≥2θ, β≥2θand β≥2θ.SELECTED DRAWING: Figure 1
