Description

Technical Field

[0001] The present invention relates to the technical field of battery thermal insulation pad packaging, and in particular to a battery module thermal insulation pad packaging process. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages of energy conservation and environmental protection. With the increase in the market share of electric vehicles, safety performance has also become one of the competitive parameters of electric vehicles, which puts higher requirements on the safety performance of electric vehicles. The power source of electric vehicles is usually a battery pack composed of multiple groups of battery cells. The damage and spontaneous combustion of a single battery cell can easily affect the remaining battery cells in the battery pack, increasing the probability of failure of the entire battery pack. Especially for the lithium battery cells used in daily life, the fire will spread rapidly after it catches fire, further causing explosions and causing casualties.

[0003] When existing equipment packages thermal insulation pads, the thermal insulation pads are easily offset during the packaging and feeding process, which causes the deviation in the packaging position and affects the product quality.

The thermal insulation pad to be processed is placed on the support plate, and an external force is applied to the thermal insulation pad at the same time, so that the support plate is forced to move downward, and then the spring is deformed under the pressure of the support plate, and the round rod drives the middle rods on both sides to move in the direction away from the round rod inside the annular groove through the middle plates on both sides, so that the support plate and the bent plate are separated. At this time, the thermal insulation pad is located in the middle of the support plate and the bent plate, and the external force disappears. Under the elastic force of the spring, the support plate drives the round rod to reset, and the round rod drives the middle rods on both sides to move toward the middle, thereby causing extrusion between the bent plate and the two sides of the thermal insulation pad, so that the insulation can be The thermal pad is flattened so that it maintains a good flat state when entering the packaging process, thereby improving the sealing and uniformity of the heat-sealed edge of the thermal insulation pad.
