Problems solved by technology

However, there will still be a small number of plates that are within the allowable weight range in manufacturing but outside the target weight range
Therefore, if you do not use plates that exceed the target weight range, the glue containing the core material, active materials, etc. will be wasted
No device or method has been proposed that can suppress variations in battery performance while using such plates.

no. 1 Embodiment approach

[0042] Hereinafter, a first embodiment of the electrode plate lamination apparatus of the present invention will be described. In this embodiment, an apparatus and method for manufacturing a laminate of a nickel-hydrogen battery will be described as an example. The nickel metal hydride battery is a sealed battery and is used as a power source for an electric vehicle or a hybrid vehicle. The nickel-metal hydride battery has a laminated body formed by laminating a positive electrode plate and a negative electrode plate with a separator interposed therebetween.

[0043] (Structure of battery manufacturing equipment)

[0044] Such as figure 1 As shown, the electrode plate lamination apparatus includes a negative electrode case MA for accommodating the negative electrode plate AP and a positive electrode case MC for accommodating the positive electrode plate CP. The negative electrode plate is produced by coating a paste containing a hydrogen storage alloy powder as an active m...

no. 2 Embodiment approach

[0092] Next, a second embodiment in which the battery manufacturing apparatus and the battery manufacturing method of the present invention are embodied will be described. In addition, since the second embodiment is only a structure in which a part of the electrode plate lamination apparatus of the first embodiment is changed, many of the same parts are given the same and detailed description thereof will be omitted.

[0093] Such as Figure 6 As shown, the electrode plate lamination apparatus which is the battery manufacturing apparatus of this embodiment is equipped with the 1st table TA and the 2nd table TB on the base 12. Each table TA, TB is rotated by the table rotation mechanism 21 . In addition, the base 12 itself is also rotatably supported by the base 11 arranged below it. A base rotation mechanism 23 including a drive source and the like is connected to the base 12 . The base rotation mechanism 23 is driven by the lamination control device 20 .

Abstract

The invention provides a polar plate lamination device capable of inhibiting the deviation of the battery performance caused by the weight difference of the glue coated on the polar plate. According to the polar plate lamination device, in at least one part of the positive polar plate and the negative polar plate, the weight of the polar plate lighter than the reference stage of the target weight of the polar plate is defined as the first stage, and the weight of the polar plate heavier than the reference stage of the target weight of the polar plate is defined as the second stage. The polar plate lamination device is provided with a clamp, which is provided with lamination area used for separating the laminated polar plates by using separators; a conveying part, which can be used to laminate the polar plate disposed on the polar plate carrying part on the clamp; and a lamination control device, which is used to control the conveying part.

Description

technical field [0001] The present invention relates to an electrode plate lamination device for laminating a plurality of electrode plates coated with an active material-containing glue with a separator interposed therebetween. Background technique [0002] Nickel-hydrogen storage batteries, lithium-ion storage batteries, and the like generally include a laminate formed by laminating a plurality of negative electrode plates and positive electrode plates with separators interposed therebetween, and the laminate is sealed in a battery case together with an electrolytic solution. A sintered type electrode plate or a gel type electrode plate is used as the negative electrode plate and the positive electrode plate. The sintered pole plate is manufactured by sintering nickel powder in a reducing atmosphere to produce a porous plate, and filling the porous plate with active materials. However, the gel plate does not require a sintering process or an impregnation process, so the g...
