Example Embodiment

[0021] Such as figure 1 with figure 2 A battery liquid injection production line shown includes a rack, a liquid injection conveying line 18, and a tray conveying line 10. The liquid injection conveying line 18 and the tray conveying line 10 pass through the rack, and the liquid injection conveying line 18 is located on the tray conveying line 10. Above. The rack is provided with a tray pressing device 4, a liquid injection device, and a vacuum device in sequence. There is also a front working platform, a rear working platform and a control box19.

[0022] The front working platform is equipped with a front electronic scale 1 and a front hand-pushing conveyor line 2. The front electronic scale 1 is used to weigh the battery cells without liquid injection. The control box 19 is equipped with a control module PLC, and the front electronic scale 1 weighs After weighting, the obtained weight value is sent to the control module for storage and memory. The rear working platform is ...

Abstract

The invention discloses a liquid-injecting method of a battery and a liquid-injecting production line thereof. The method comprises the following steps of: a) putting an electric core which is not injected with liquid on a front weighing device to weigh, and memorizing the weight value of the electric core which is not injected with the liquid in a control module; b) putting the electric core which is not injected with the liquid in a tray, and putting the tray on the liquid-injecting production line; c) injecting the liquid to the eclectic core by the liquid-injecting device at the tray which is put with the electric core, and vacuuming the electric core by a vacuuming device; and d) putting the electric core which is injected with the liquid on a back weighing device to weigh, and memorizing the obtained weight value of the electric core which is injected with the liquid in the control module; and e) comparing the weight value of the electric core which is not injected with the liquid with the weight value of the electric core which is injected with the liquid by the control module, if the different value exceeds a set value, supplying the liquid to the electric core. Each of the trays is provided with the plurality of electric cores. The invention is provide with the control module for memorizing and comparing the weight value of the electric core before and after liquid injection, has exact weighing and high automation degree, and improves the work efficiency of the production line.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to a battery liquid injection method and a battery liquid injection production line. Background technique [0002] A lithium-ion battery generally includes a battery case, a pole core and a non-aqueous electrolyte contained in the battery case. The production method is generally to make the positive electrode, the negative electrode and the diaphragm into the pole core, place the pole core in the battery case, cover the cover plate, and there is a liquid injection hole on the cover plate, and inject the battery from the liquid injection hole through the liquid injection device. A non-aqueous electrolyte is injected into the battery case. The electrolyte is an important part of the battery, so the liquid injection process is a very important link in the battery production process. The amount of electrolyte in the battery is related to the battery capacity and cycle life. Insuff...
