Description

Technical Field

[0001] The present invention relates to the technical field of packaging and assembling lithium battery square cell modules, and in particular to an automatic extrusion packaging detection device for square cell modules. Background Art

[0002] In recent years, lithium-ion batteries have been widely used in electric vehicles. As the internet has evolved from the information dissemination era to the information application era, and with the full development of integrated circuit technology, product R&D and distribution costs have become increasingly lower, and cycles have become increasingly faster. This has ushered in an era of explosive product development. A continuous stream of new electrical products has driven up the market for lithium-ion batteries, which have begun to replace lead-acid batteries in industrial and household energy storage, two-wheeled vehicles, utility vehicles, and UPS systems. As demand for power battery production capacity continues to increase, the use of related automation equipment has also increased.

[0003] When assembling square battery cells into modules, they must first be shaped and compacted, and then packaged. Existing battery module packaging equipment has a low degree of automation. For example, patent document CN110957521A discloses a square battery cell module regular compacting and packaging machine. This packaging machine automatically compacts or presses the six sides of the square battery cell module using a bottom flattening assembly, a top compacting assembly, a compacting and locking assembly, a blocking assembly, a lifting and compacting assembly, and a bottom assembly. The square battery cell module is then manually packaged into a whole using a packaging machine. During the packaging process, personnel manually thread the strapping tape and tighten the hot-melt strapping tape using a handheld packaging machine, which is labor-intensive and inefficient. During transportation, the battery cells loosen and the manual packaging force is uneven, resulting in large errors in the flatness of all battery cells. The uneven top of the module directly affects the quality of subsequent laser welding, resulting in a very low product qualification rate. After manual packaging, a separate flatness test is required, which takes a long time to complete, affecting production efficiency. Summary of the Invention
