Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery sorting, in particular to a lithium battery sorting machine. Background Art

[0002] With the widespread use of lithium batteries in various electronic devices and electric vehicles, the quality and performance requirements of lithium batteries are becoming increasingly stringent. In the production process of lithium batteries, it is crucial to ensure that the voltage and resistance of each battery meet the standards. Therefore, in the testing stage of lithium battery production, it is usually necessary to use a sorting machine to sort the voltage and resistance of the battery to ensure that only qualified batteries can enter the subsequent production process. At present, the single-station resistance and voltage sorting machine commonly used in the market is the core equipment for lithium battery testing and sorting. It mainly classifies the battery by measuring the internal resistance and voltage value of the battery. The single-station resistance and voltage sorting machine generally uses one test station to complete the resistance and voltage measurement of each battery, and sorts the battery according to preset standards.

[0003] However, the existing single-station resistance and voltage sorting machine has some disadvantages:

[0004] 1. Low production efficiency: Due to the single-station design, the voltage and resistance tests of the batteries can only be performed one by one, which results in only a limited number of batteries being processed per unit time and cannot meet the needs of large-scale production. Especially in the production process of lithium batteries, the testing link becomes a bottleneck in the production process, resulting in low overall production efficiency.

[0005] 2. Complex operation: Existing sorting machines require manual placement and removal of batteries by humans or robotic arms. The operation of each station is relatively cumbersome, which can easily lead to operator errors or battery damage, further affecting product quality.

[0006] 3. Lack of high precision and consistency: In the use of single-station sorting machines, there are often certain errors in the resistance and voltage tests of the batteries. Especially in situations where high precision is required, the accuracy and consistency of existing equipment are difficult to meet the sorting requirements of high-end lithium batteries.

[0007] 4. Unable to handle the requirements of mass production: As the scale of battery production continues to expand, single-station resistance voltage sorting machines cannot efficiently process more batteries, greatly limiting the improvement of production capacity. In order to increase production capacity, it is often necessary to increase the number of equipment or increase production lines, but this will lead to increased equipment investment and waste of space resources.

[0008] 5. High maintenance cost: Since the equipment is sophisticated and complicated to operate, once a failure or adjustment is required, the maintenance cost is high. In addition, long-term use may cause equipment aging, affecting the accuracy of the test and the sorting effect. No solution has been proposed for related technical problems.
