[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0037] In this application, unless otherwise clearly specified and limited, the terms "installation", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0039] The battery consists of battery cells. After the battery cells are formed, they are transported to the sorting station through the assembly line for sorting. After that, the trays loaded with battery cells in batches are manually transported off the line and the trays are manually washed. This manual operation method is time-consuming and labor-intensive, and has low operating efficiency.

[0040] See also Figure 1 , Figure 2 and Figure 3 In order to alleviate the problem of low operating efficiency caused by the manual operation of carrying pallets off the line and manually washing them, the applicant has designed a battery manufacturing production line 1 through in-depth research. The battery manufacturing production line 1 includes a main pipeline 10, a cleaning line 20 and a cleaning device 30. The main pipeline 10 is used to transport full pallets of battery cells after formation and empty pallets 13 of sorted battery cells after formation. The cleaning line 20 is located on one side of the main pipeline 10 and has a cleaning area. The cleaning line 20 is used to remove the empty pallets 13 on the main pipeline 10 and transport the empty pallets 13 through the cleaning area and then return to the main pipeline 10. The cleaning device 30 is used to clean the empty pallets 13 located in the cleaning area.

[0041] The main pipeline 10 has a formation offline station and a sorting station 16. The main pipeline 10 transports the fully loaded tray from the formation offline station to the sorting station 16 for sorting.

[0042] The formation offline station refers to the station where the main assembly line 10 receives the full pallet delivered by the formation assembly line. The sorting station 16 refers to the station where the qualified and defective battery cells in the full pallet are selected and separated so that the full pallet can form an empty pallet 13. After sorting, the qualified products can be packed together to form a battery pack, and the defective products can be recycled. The full pallet forms an empty pallet 13 after the sorting is completed at the sorting station 16.

[0043] In actual operation, after the fully loaded pallets are transported to the sorting station 16 through the main pipeline 10 for sorting and forming empty pallets 13, they are transferred back to the main pipeline 10 by means of a driving device or an assembly line, and pass through the cleaning area and are cleaned under the action of the cleaning assembly line 20. Automatically cleaning the empty pallets 13 using the cleaning device 30 is simple and labor-saving, thereby saving time for washing the empty pallets 13 to a certain extent, which is conducive to improving the operation efficiency. In addition, the cooperation between the main pipeline 10 and the cleaning assembly line 20 can also realize the integration and intelligence of sorting and cleaning.

[0044] Exemplarily, the cleaning line 20 and the cleaning device 30 are used in combination. In practical applications, the cleaning line 20 and the cleaning device 30 can be set as one set or multiple sets, for example, two sets, according to needs. The multiple sets of cleaning lines 20 and cleaning devices 30 that are arranged in combination are arranged along the conveying direction of the main pipeline 10, and are distributed on the same side or opposite sides of the main pipeline 10. Specifically, each set of cleaning lines 20 and cleaning devices 30 can cooperate and clean the empty pallets 13, and different sets of cleaning lines 20 and cleaning devices 30 are used to clean different empty pallets 13. Multiple sets of cleaning lines 20 and cleaning devices 30 cooperate, so that different sets of cleaning lines 20 and cleaning devices 30 can clean different empty pallets 13 at the same time, and the cleaning efficiency is high.

[0045] Please refer again Figure 1 and Figure 3 In some embodiments, the cleaning area has a first flipping station 21, a cleaning station 22, a drying station 23 and a second flipping station 24 arranged in sequence along the conveying direction of the cleaning line 20; the cleaning device 30 includes a first flipping mechanism, a cleaning mechanism, a drying mechanism and a second flipping mechanism, the first flipping mechanism is used to drive the empty pallet 13 located at the first flipping station 21 to flip forward at a preset angle, the cleaning mechanism is used to clean the empty pallet 13 located at the cleaning station 22, the drying mechanism is used to dry the empty pallet 13 located at the drying station 23, and the second flipping mechanism is used to drive the empty pallet 13 located at the second flipping station 24 to flip backward at a preset angle.

[0046] The cleaning mechanism is used to spray cleaning liquid and clean the open cavity of the empty tray 13 to remove dust, debris or other sundries in the open cavity.

[0047] Exemplarily, the cleaning mechanism may be a spray gun, a shower head, or other mechanism capable of spraying high-pressure cleaning fluid. The cleaning fluid may be a fluid having a cleaning function, such as water or alcohol. It should be noted that the types of the cleaning mechanism and the cleaning fluid, as well as the location of the cleaning mechanism, can be set according to actual needs.

[0048] The drying mechanism is used to dry the cleaning liquid in the empty tray 13 to facilitate the subsequent storage or loading of battery cells on the empty tray 13 .

[0049] Exemplarily, the drying mechanism may be a mechanism capable of blowing hot air, such as an oven or a heater. The drying mechanism may be located above and / or below the washing line 20. For example, the drying mechanism being located above and below the washing line 20 means that there are two drying mechanisms, one of which is located above the washing line 20 and the other is located below the washing line 20, so as to dry the empty tray 13 from both the upper and lower sides of the empty tray 13.

[0050] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0052] It should be noted that the specific form, quantity and location of the drying mechanism can be set according to actual needs and are not limited here.

[0053] The first flipping mechanism is used to drive the empty tray 13 to flip forward to a preset angle so that the open mouth of the unwashed empty tray 13 can be placed toward the cleaning mechanism, and the second flipping mechanism is used to drive the dried empty tray 13 to return to its original direction.

[0054] As an example, the first flip mechanism and the second flip mechanism may have the same or different structures. Taking the first flip mechanism and the second flip mechanism having the same structure as an example, the first flip mechanism and the second flip mechanism may both be four-axis manipulators, five-axis manipulators, and the like.

[0055] In the embodiments of the present application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0056] As an example, the preset angle may be 90°, 180°, etc. Taking the case where the open cavity of the empty tray 13 on the main pipeline 10 faces upward and the cleaning mechanism is located below the cleaning pipeline 20 as an example, the preset angle is 180°. The open cavity of the empty tray 13 after being flipped by the first flipping mechanism faces downward, and the open cavity of the empty tray 13 after being flipped by the second flipping mechanism faces upward.

[0057] During actual operation, the empty pallet 13 passes through the first turning station 21, the cleaning station 22, the drying station 23 and the second turning station 24 in sequence, and performs forward turning, cleaning, drying and reverse turning in sequence. This design optimizes the traditional operation method of manually transporting the empty pallet 13 between the cleaning area and the drying area, which is beneficial to improving the cleaning and drying efficiency.

[0058] In some embodiments, the main pipeline 10 has a first switching station 13 and a second switching station 14 arranged in sequence along its conveying direction; wherein the first switching station 13 refers to a station where an empty tray 13 to be cleaned on the main pipeline 10 is waiting for or is being switched to the cleaning line 20. The second switching station 14 refers to a station where the main pipeline 10 receives the cleaned empty tray 13 sent by the cleaning line 20. The cleaning line 20 is used to remove the empty tray 13 located at the first switching station 13, and transport the empty tray 13 through the cleaning area to the second switching station 14.

[0059] In actual operation, when the empty tray 3 reaches the first switching station 13, it is removed by the cleaning line 20, and then passes through the first flipping station 21, the cleaning station 22, the drying station 23 and the second flipping station 24 in sequence to perform the cleaning, drying and flipping operations. After that, the cleaning line 20 transfers the empty tray 13 to the second switching station 14 of the main line 10.

[0060] The main pipeline 10 also has a third switching station 11, a lower tray storage station 12 and a fourth switching station arranged along its conveying direction. The fourth switching station refers to a station where the cleaned empty pallet 13 is waiting for or is being switched to the third switching station 11 upstream thereof, the third switching station 11 refers to a station where the cleaned empty pallet 13 passes before being unloaded from the main pipeline 10, and the lower tray storage station 12 refers to a station where the cleaned empty pallet 13 is unloaded from the main pipeline 10. The third switching station 11 and the lower tray storage station 12 are both located upstream of the first switching station 13, the fourth switching station overlaps with the second switching station 14, or the fourth switching station is located downstream of the second switching station 14. The battery manufacturing production line 1 includes a first switching assembly line 40, which is used to transport the empty pallet 13 of the fourth switching station to the third switching station 11, and then the main assembly line 10 transports the empty pallet 13 of the third switching station 11 to the lower tray storage station 12.

[0061] In the actual working process, when the fourth switching station coincides with the second switching station 14, the first switching assembly line 40 transports the cleaned empty pallet 13 from the second switching station 14 to the third switching station 11. When the fourth switching station is located downstream of the second switching station 14, the main switching assembly line 10 transports the cleaned empty pallet 13 from the second switching station 14 to the fourth switching station, and then the first switching assembly line 40 transports the empty pallet 13 located at the fourth switching station to the third switching station 11. Afterwards, the cleaned empty pallet 13 is transferred from the third switching station 11 to the lower tray storage station 12 through the main assembly line 10, and the empty pallet 13 is transferred to the shelf 2 for storage through a gripping mechanism such as a three-axis manipulator or a four-axis manipulator.

[0062] When the fourth switching station overlaps with the second switching station 14, it is beneficial to shorten the running time of the cleaned empty tray 13 on the main pipeline 10, which is convenient for improving production efficiency. When the fourth switching station is located downstream of the second switching station 14, the fourth switching station and the second switching station 14 are separately arranged, which can increase the length of the main pipeline 10 and have a larger detection throughput. For the convenience of explanation, the following embodiments are all described as an example in which the fourth switching station is located downstream of the second switching station 14. In addition, the first switching assembly line 40 cooperates with the main assembly line 10 and the cleaning assembly line 20 to automatically realize the cleaning and storage of the empty trays 13 without repeated manual handling, and the rotation cycle is short, the space occupied is small, and the operation efficiency is high.

[0063] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the main pipeline 10 further has a fifth switching station 15 and a sorting station 16. In the conveying direction of the main pipeline 10, the fifth switching station 15 is located upstream of the third switching station 11, and the sorting station 16 is located downstream of the fourth switching station.

[0064] The battery manufacturing production line 1 also includes a second switching assembly line 50, which is used to transport the empty trays 13 of the sorting station 16 to the fifth switching station 15, wherein the empty trays 13 of the sorting station 16 are formed by sorting the full trays.

[0065] During actual operation, the empty pallet 13 of the sorting station 16 is transported to the fifth switching station 15 through the second switching line 50, so that the empty pallet 13 can be subsequently carried by the main pipeline 10 and pass through the third switching station 11, the lower plate storage station 12 and the first switching station 13 in sequence, and enter the cleaning area of ​​the cleaning line 20 for cleaning.

[0066] The second switching assembly line 50 is set up, and after the full tray is sorted to form an empty tray 13, it is automatically transported to the station located upstream of the first switching station 13 on the main assembly line 10 under the drive of the second switching assembly line 50, so as to facilitate subsequent automatic cleaning. This method does not require manual handling, saves time and labor, and has high operating efficiency.

[0067] See also Figure 1 and Figure 3 In some embodiments, the battery manufacturing production line 1 further includes a vibration assembly line 60 and a vibration device 70. The vibration assembly line 60 and the cleaning assembly line 20 are located on the same side of the main assembly line 10 or on opposite sides, and the vibration assembly line 60 is located upstream or downstream of the cleaning assembly line 20 along the conveying direction of the main assembly line 10. The vibration assembly line 60 has a vibration station 61, and the vibration assembly line 60 is used to remove the fully loaded pallet on the main assembly line 10 and transport the fully loaded pallet through the vibration station 61 and then return to the main assembly line 10; the vibration device 70 is used to perform vibration resistance test on the battery cells in the fully loaded pallet located at the vibration station 61, so as to simulate the working conditions of the battery cells when in use and test the vibration resistance effect of the battery cells.

[0068] Exemplarily, the main pipeline 10 further comprises a vibrating tray inlet station 17 and a vibrating tray outlet station 18, which are arranged along the conveying direction of the main pipeline 10. When a fully loaded pallet is transported to the vibrating tray inlet station 17, it is transported to the vibrating station 61 by means of the vibrating assembly line 60, and after the vibration is completed, the vibrating assembly line 60 transports the fully loaded pallet to the vibrating tray outlet station 18.

[0069] It is worth mentioning that Figure 1 Taking the battery manufacturing production line 1 shown as an example, in the embodiment, the vibration assembly line 60 is located downstream of the cleaning assembly line 20 in the conveying direction of the main assembly line 10. At this time, the fourth switching station is located downstream of the second switching station 14 and overlaps with the vibration tray output station 18.

[0070] For example, the vibration device 70 may be a motor vibrator or a compressed air vibrator. The structure of the vibration device 70 is not limited to the above-mentioned ones, and can be specifically set according to the requirements.

[0071] Exemplarily, the vibration assembly line 60 and the cleaning assembly line 20 are located on the same side of the main assembly line 10. In this case, the vibration assembly line 60, the cleaning assembly line 20 and the main assembly line 10 are more compactly arranged, and the battery manufacturing production line 1 occupies less space. It should be noted that the assembly method between the vibration assembly line 60 and the cleaning assembly line 20 in the embodiment of the present application is not limited thereto, and the vibration assembly line 60 and the cleaning assembly line 20 can also be installed on opposite sides of the main assembly line 10.

[0072] The vibration assembly line 60 is used in conjunction with the vibration device 70. In practical applications, the vibration assembly line 60 and the vibration device 70 can be set as one set or multiple sets, for example, two sets, according to needs. Specifically, each set of the vibration assembly line 60 and the vibration device 70 can cooperate and vibrate the fully loaded pallet, and different sets of vibration assembly lines 60 and vibration devices 70 are used to vibrate different fully loaded pallets. The multiple sets of vibration assembly lines 60 and vibration devices 70 that are arranged in conjunction are arranged along the conveying direction of the main assembly line 10, and are distributed on the same side or opposite sides of the main assembly line 10. Multiple sets of vibration assembly lines 60 and vibration devices 70 cooperate, so that different sets of vibration assembly lines 60 and vibration devices 70 can vibrate different fully loaded pallets at the same time, and the production efficiency is high.

[0073] See also Figure 1 , Figure 2 and Figure 4 The battery manufacturing production line 1 further includes a testing device 80. The main pipeline 10 has a testing station 19, which is arranged downstream of the vibration pipeline 60 along the conveying direction of the main pipeline 10. The testing device 80 is used to test the voltage and internal resistance of the battery cells in the fully loaded tray carried to the testing station 19 after vibration to determine whether the battery cells meet the quality requirements.

[0074] Exemplarily, the testing device 80 may be an OCV (open circuit voltage) testing machine or the like.

[0075] The battery manufacturing production line 1 also includes a sorting line 110. The sorting line 110 and the cleaning line 20 are located on the same side of the main pipeline 10 or on opposite sides, and the sorting line 110 is located downstream of the cleaning line 20 and the vibration line 60 along the conveying direction of the main pipeline 10. The sorting line 110 has a qualified product channel and a defective product channel.

[0076] The main pipeline 10 has a sorting station 16 , which is located downstream of the testing station 19 along the conveying direction of the main pipeline 10 .

[0077] The battery manufacturing production line 1 also includes a sorting device 90, which is located between the main assembly line 10 and the sorting assembly line 110, and is used to sort the battery cells in the full-loaded tray located at the sorting station 16 into a qualified product channel or a defective product channel; wherein, the full-loaded tray is sorted to form an empty tray 13.

[0078] Exemplarily, the sorting device 90 may be a three-axis robot, a four-axis robot, or the like.

[0079] Among them, the sorting line 110 has a packaging station and a recycling station. Qualified products are transported to the packaging station through the qualified product channel of the sorting line 110 and packaged, and defective products are transported to the recycling station through the defective product channel of the sorting line 110 for recycling.

[0080] Among them, the battery cells that are qualified in the formation test, vibration test, voltage and resistance test are qualified products. The battery cells that fail at least one of the formation test, vibration test, voltage and resistance test are defective products.

[0081] The arrangement of the sorting device 90 and the sorting assembly line 110 transfers the battery cells to corresponding channels according to the test results of the battery cells, which is conducive to the centralized packaging or recycling of the battery cells.

[0082] Below, Figure 1 Taking the battery production line as an example, the working process of the battery production line is explained in detail.

[0083] Under the action of the main pipeline 10, the fully loaded pallet passes through the third switching station 11, the lower tray storage station 12, the first switching station 13 and the second switching station 14 in sequence, and arrives at the vibration tray entry station 17. Afterwards, with the help of the action of the vibration assembly line 60, the fully loaded pallet passes through the vibration station 61 and vibrates. After the vibration, the fully loaded pallet is transported by the vibration assembly line 60 to the vibration tray exit station 18 on the main pipeline 10, and then is driven by the main pipeline 10 in sequence and passes through the testing station 19 and the sorting station 16. When the fully loaded pallet is at the sorting station 16, the sorting device 90 sorts the battery cells in the fully loaded pallet into the qualified product channel or the defective product channel to form an empty pallet 13 (the transportation path of the fully loaded pallet is shown in arrow a 1 →a 2 →a 3 →a 4 →a 5 →a 6 →a 7 →a 8 →a 9 →a 10 →a 11 →a 12 →a 13 →a 14 →a 15 shown).

[0084] Then, the second switching assembly line 50 drives the empty pallet 13 formed after sorting to the fifth switching station 15.
