Description

Technical Field

[0001] The utility model relates to the technical field of integrated battery module detection, in particular to an integrated battery module overall polarity detection device. Background Art

[0002] Intelligent warehousing and logistics engineering equipment is widely used in the field of warehousing and logistics. Intelligent warehousing and logistics engineering equipment includes transportation tools, warehousing facilities, packaging equipment, distribution equipment, etc. At present, more and more intelligent warehousing and logistics engineering equipment are beginning to adopt electric drive. The battery life directly affects the operating status and work efficiency of intelligent warehousing and logistics engineering equipment. In order to extend the battery life of intelligent warehousing physical engineering equipment, the existing technology usually assembles multiple batteries in series and parallel into a battery integrated module for use. When assembling the battery integrated module, the battery cells need to be connected for polarity. If the battery electrodes are reversed during the installation of the battery integrated module, the battery integrated module will be damaged at the least, and the battery integrated module will explode during use and injure personal safety. Therefore, after the battery integrated module is assembled, the battery integrated module needs to be tested for polarity, and only qualified battery integrated modules can be used.

[0003] There are usually two ways to detect the polarity of existing battery integrated modules. The first is to assign quality inspectors to visually inspect the installation of battery electrodes during battery integrated module assembly when the number of battery integrated module assembly inspections is small, or to arrange two groups of quality inspectors to repeat the inspection. Although the first method can achieve the purpose of electrode detection during battery installation, it is extremely inefficient and has a high error rate in quality inspection. The second is that the number of battery integrated modules assembled is large, that is, the battery integrated modules are assembled through an automated production line, and the number of battery integrated modules involved in the inspection is large. Enterprises use industrial cameras, industrial computers and other instruments to process information to monitor the battery assembly process and capture images, and the captured images are The image data is compared to determine whether the polarity installation of the battery is qualified during the assembly of the battery integrated module. Although the second method has fast detection speed and high accuracy, it requires the installation of expensive equipment and requires a lot of equipment debugging, as well as the use of software and programs. The second method has relatively high inspection conditions and costs, and is relatively cumbersome to operate. Therefore, it is not applicable to the battery polarity detection task of the battery integrated module when the number of battery integrated module assembly inspections is small. In order to solve the problem of high misjudgment rate of battery polarity detection of the battery integrated module through manual inspection when the number of battery integrated module assembly inspections is small, a battery integrated module overall polarity detection device is developed.
