It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0022] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and they themselves have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0023] See attached Figure 1-2The utility model discloses a battery cell processing system, including a battery cell processing chamber, wherein the processing chamber includes a plurality of chamber groups with different process sections, and different processing processes are performed when the battery cells are transported to each chamber group. Each processing chamber includes more than two sub-chambers, wherein the sub-chamber is a separate chamber, and each sub-chamber serves the same processing process. In simple terms, the processes of multiple sub-chambers in the same chamber group are the same, while the processes of different chamber groups are different.

[0024] Each chamber group of the present invention is provided with a vacuum pump 1, that is, for the same processing technology, a vacuum pump 1 is provided, and the vacuum pump 1 is simultaneously connected to each sub-chamber of the same chamber group, and each sub-chamber of the same chamber group is evacuated by the vacuum pump 1, so that the pressure in each sub-chamber of the same chamber group is consistent. Each sub-chamber is connected to the vacuum pump 1 through a pipeline, and the pipeline of each sub-chamber is provided with a valve, and each chamber group is provided with a control system, and the control system is electrically connected to the valve to control the flux of the pipeline of each sub-chamber.

[0025] It should be noted that the sub-chamber here is usually rectangular, and for a rectangle, it includes four sides, of which the short side is called the end and the long side is called the side. The transportation path of the battery cell is usually through two opposite sides, that is, entering the sub-chamber from one side and exiting the sub-chamber from the other opposite side, thereby increasing the transportation area and the transportation volume of the battery cells. The vacuum pump 1 of each chamber group is set at the end of the sub-chamber, that is, the non-transportation side, to avoid hindering the transportation of the battery cells.

[0026] The utility model connects multiple processing chambers that need to be set to the same pressure to the same vacuum pump 1 through pipelines, and sets valves on the pipelines to adjust the flux in the pipelines respectively through the valves, so that the vacuum pump 1 can adjust the vacuum pumping rate of the multiple processing chambers respectively, thereby realizing the same vacuum pump 1 to control the pressure of the multiple processing chambers separately.

[0027] Preferably, the processes in different process sections include a loading process and an unloading process, wherein the loading process is to load the battery cells onto a carrying container, usually a carrier plate, and the unloading process is to remove the battery cells from the carrying container (such as a carrier plate). Then, the chamber groups of the several different process sections described above include a loading chamber group and an unloading chamber group.

[0028] Preferably, the chamber group includes a working chamber 2 and a balancing chamber 3. The working chamber 2 is used for processing the battery cells (such as loading and unloading), and the balancing chamber 3 is used to balance the pressure of the working chamber 2. Usually, the pressures in the working chamber 2 and the balancing chamber 3 need to be kept consistent. The vacuum pump 1 is arranged at one end of the working chamber 2, that is, the non-battery cell transportation side mentioned above. A transmission shaft is arranged in the working chamber 2 and the balancing chamber 3, and a conveyor belt is arranged on the transmission shaft. The battery cells are placed on the conveyor belt. The transmission shaft rotates, thereby driving the conveyor belt to run, and then driving the battery cells to pass through the working chamber 2 and the balancing chamber 3.

[0029] The pipes used for connection include a first sub-pipe 5, a second sub-pipe 6, a third sub-pipe 7 and a fourth sub-pipe 8. The first sub-pipe 5 is connected to the vacuum pump 1, specifically to the air extraction port of the vacuum pump 1, and the second sub-pipe 6 is connected to the working chamber 2, specifically to the air outlet of the working chamber 2; the first sub-pipe 5, the second sub-pipe 6 and the third sub-pipe 7 are connected through a tee pipe 4. The third sub-pipe 7 is connected to the balance chamber 3, specifically to the air outlet of the balance chamber 3, and due to the size limitation of the working chamber 2 and the balance chamber 3, the third sub-pipe 7 coming out of the balance chamber 3 cannot be directly connected to the tee pipe 4, so the third sub-pipe 7 is connected to the tee pipe 4 through the fourth sub-pipe 8.

[0030] The three-way pipe 4 here includes a first main port and a second main port located on the same path, and a branch port perpendicular to the first main port / second main port. The first sub-pipe 5 is connected to the first main port, the second sub-pipe 6 is connected to the second main port; the fourth sub-pipe 8 is connected to the branch port; because the connection path between the third sub-pipe 7 and the fourth sub-pipe 8 is changed, the third sub-pipe 7 and the fourth sub-pipe 8 are connected through the first elbow. It can be understood that the vacuum pump 1 is mainly connected to the working chamber 2, that is, the main exhaust path leads to the working chamber 2, and the balance chamber 3 is connected through a branch route on the main exhaust path.

[0031] The connection between the first sub-tube 5, the second sub-tube 6, the third sub-tube 7 and the fourth sub-tube 8 and the three-way pipe 4, as well as the connection between the sub-tube and the elbow are achieved by bolts. When the size of each sub-tube needs to be adjusted to adapt to different air extraction paths, they can be disassembled by bolts.

[0032] Furthermore, the heights of the vacuum port of the vacuum pump 1 and the air outlet of the working chamber 2 are inconsistent, so a first sub-tube 5 is connected to the first main port through a second elbow, and a second sub-tube 6 is connected to the second main port through a third elbow.

[0033] Preferably, the valve is an angle valve 9. In other embodiments, other valves can also be used for control, which is not limited here.

[0034] Preferably, pressure detection modules are respectively provided in the working chamber 2 and the balancing chamber 3, and the pressure detection modules are connected to the control system and are used to detect the pressures in the working chamber 2 and the balancing chamber 3 respectively; when the pressures are inconsistent or the target pressure is not reached, prompts are given in time through the control system.

[0035] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
