Embodiment

[0052] A battery packaging method according to a specific embodiment of the present invention is described below.

[0053] Step 1: Apply oil to the neck 2 of the battery with a rotating brush. The oil dripping interval of the rotating brush is 600s, and the oil dripping time is 3s each time;

[0054] Step 2: Set the heat-shrinkable sleeve 4 on the battery, and the heat-shrinkable sleeve 4 covers the neck portion 2, the body portion 3 and a part of the head 1, wherein the thickness of the heat-shrinkable sleeve 4 is 0.06mm-0.75mm;

[0055] Step 3: Use annular heat-shrinking equipment to heat-shrink the heat-shrinkable sleeve 4 for the first time, the heat-shrinking time is 6s-8s, and the heat-shrinking temperature is 300°C-340°C;

[0056] Step 4: Use a horizontal heat-shrinking device to shrink the heat-shrinkable sleeve 4 for the second time. The heat-shrinking time is 66s-72s, and the heat-shrinking temperature is 100°C-110°C.

Abstract

The invention discloses a battery packaging method. A battery comprises a head part, a neck opening part and a body part which are connected in sequence. The battery packaging method comprises the following steps: S1, the neck opening part is coated with an anti-rust oil; S2, the battery is sleeved with a thermal shrinkable sleeve, and the thermal shrinkable sleeve covers the neck opening part, the body part and one portion of the head part; and S3, thermal shrinkage is carried out on the thermal shrinkage sleeve. According to the packaging method, the thermal shrinkage coating size can be controlled, the probability of creases on the thermal shrinkage sleeve can be well reduced, the appearance yield of the battery can be improved, and the size of the battery after thermal shrinkage can becontrolled, so that normal assembly for a battery module is facilitated.

Description

technical field [0001] The invention relates to the technical field of battery production and manufacturing technology, in particular to a battery packaging method. Background technique [0002] Oiling the surface of the bare-case battery can effectively prevent the battery from rusting. However, the way of oiling is very important. Improper oiling direction will affect the size of the heat-shrinkable coating, which will lead to a high defect rate of the appearance of the battery (about 2%. Good product). At the same time, it is necessary to put a heat shrinkable sleeve on the bare case battery after oiling. At present, the existing heat shrinking process will cause more obvious creases on the surface of the battery after the heat shrink is completed. Assembly of modules. Contents of the invention [0003] The purpose of the present invention is to propose a battery packaging method, which can control the size of the heat shrink wrap and better reduce the probability of...
