Background

During formation and capacity grading of the lithium battery, large current needs to be conducted between the positive electrode and the negative electrode of each battery for charging and discharging, meanwhile, a voltage signal and a temperature signal of each battery need to be collected, and in addition, a liquid injection port of each battery needs to be connected to a vacuum pipeline so as to timely remove a large amount of gas generated during formation of an SEI (solid electrolyte interphase) oxide film. Generally, 2 sets of probes (each set of probes comprises a large-current probe and a voltage signal probe and totally 3 leads), a thermistor (totally 2 leads) and a vacuum negative pressure pipeline are needed for one battery, the total number of the warehouse positions of a needle bed of a formation and partial volume production line is hundreds under general conditions according to different capacity requirements, one warehouse position is provided with 8-32 channels, generally, one formation and partial volume production line needs to take account of batteries with different models, the production is realized by changing the model in production, when a product line is changed, the position of the probe needs to be adjusted to align to a positive pole and a negative pole of the battery, the thermistor aligns to a negative temperature region, a negative pressure suction nozzle needs to align to a battery liquid injection port, and the total number of the leads which need to be connected with the formation and partial volume production line and the vacuum negative pressure pipeline reaches ten thousand; in addition, the probe, the thermistor and the negative pressure suction nozzle need to be increased or decreased according to the number of batteries in the tray, and the increased or decreased wires need to be connected. Due to the above mentioned situation, the connection workload of the wires and the pipelines is very huge during the model changing. In the former model changing, people climb to each storehouse position of a needle bed to carry out the adjustment and the connection work of a lead and a pipeline. Because some needle bed storehouses are in high positions and have narrow spaces, hands and feet are obstructed, the efficiency is low, two or thirty people are required to fight for half a month continuously for each type changing, the great waste of manpower and material resources is caused, the productivity is seriously influenced, and the highest storehouse of the needle bed reaches 4-5 meters, which belongs to high-altitude operation, so the danger is increased, and the situation is urgently needed to be changed in the industry.

The applicant provides a quick-change structure of a lithium battery formation and capacity-division device, as shown in fig. 1 to 8, which includes a quick-change module 101, a fixed frame 102 (a part of a needle bed), a positioning and locking device 103, a large-current quick-connection device 104, a signal line quick-connection device 105 and a vacuum negative-pressure quick-connection device 106, where the quick-change module 101 includes a square frame 107, a negative-pressure module 108, a thermistor module 109 and a probe module 110, the positioning and locking device 103 is used to position and lock the quick-change module 101 on the fixed frame 102, the probe module 110 includes a large-current probe and a voltage signal probe, the quick-connection device 104 is used to connect the large-current probe with a large-current line of the device, the signal line quick-connection device 105 is used to connect signal lines of the thermistor module and the voltage signal probe with corresponding signal lines of the device, the vacuum negative pressure quick connection device 106 is used for connecting the negative pressure module with a vacuum source of the equipment.

The quick-change module 101 can be quickly taken off from the fixed frame 102, and is adjusted outside the production line, and then is transported back to the chemical component capacity equipment after being adjusted, and is quickly connected and installed. The off-line adjusting space is large, so that a special jig for adjusting the position is convenient to use, and the adjusting efficiency is greatly improved; high-altitude operation is avoided, and safety is improved.

However, some parts of the components such as the large-current probe, the voltage signal probe, the negative pressure suction nozzle and the thermistor on the rapid prototyping module 101 are in an outward protruding state, the rapid prototyping module 101 cannot be directly placed on the RGV fork for direct carrying, and in addition, the RGV fork cannot automatically install the rapid prototyping module in a needle bed stock position of lithium battery formation capacity grading equipment, so a special prototyping jig needs to be designed.
