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, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0057] In the production process of cylindrical batteries, in order to achieve accurate traceability of battery cells, corresponding identification codes, such as QR codes or bar codes, are usually set on the peripheral walls of the battery cells, so as to accurately obtain the information of each battery cell during the transmission of the cylindrical battery cells on the production line, or adopt the tray RFID (Radio Frequency Identification) code reading method to indirectly achieve accurate traceability of the cylindrical battery cells in the tray by reading the code of the tray containing the cylindrical battery cells. When the tray RFID code reading method is adopted, since the cylindrical battery cells may be separated from the tray to perform process actions during the transportation of the production line, the cylindrical battery cells also need to be scanned and verified to reduce the risk of traceability confusion.

[0058] The device for scanning the cylindrical battery cells is arranged on the conveying line of the cylindrical battery cells. During the conveying process of the cylindrical battery cells, the scanning device scans the cylindrical battery cells when the cylindrical battery cells pass through the scanning device. At present, when the scanning device scans the cylindrical battery cells, it is necessary to first drive the cylindrical battery cells to rotate so that the identification codes on the cylindrical battery cells can be stably captured by the scanning device, so that the scanning device can stably perform the scanning operation. This requires the cylindrical battery cells to perform more scanning actions at the scanning device. For example, when the cylindrical battery is conveyed to the scanning device, the scanning device needs to control the rotation of the cylindrical battery cells. The cylindrical battery cells are in a relatively fixed position during the rotation process, so that the scanning device can perform stable scanning. After the scanning is completed, the cylindrical battery cells continue to be conveyed from this position. This makes the scanning efficiency of the scanning device for the cylindrical battery cells low, and the scanning operation rhythm is difficult to match the production rhythm of the cylindrical battery cells on the automated production line, so that the scanning device is difficult to match the needs of efficient production during the automated production of cylindrical battery cells.

[0059] Based on the above considerations, in order to improve the efficiency of code scanning and enable the code scanning device to well meet the needs of efficient production during the automated production of cylindrical battery cells, the present application designs a code scanning device. By arranging multiple code scanners at circumferential intervals along the cylindrical battery cells for scanning, the code scanning device can stably and reliably scan the identification code on the cylindrical battery cells without the need for the cylindrical battery cells to rotate or perform other operations. As a result, when the cylindrical battery cells are transported on the conveyor line, they only need to pass through the code scanning device to complete the scanning operation. The code scanning efficiency is high, which greatly reduces the impact of the code scanning operation on the production and transportation rhythm of the cylindrical battery monomers, so that the cylindrical battery monomers can maintain an efficient production rhythm, so that the code scanning device can well meet the needs of efficient production of the cylindrical battery monomers during automated production.

[0060] The cylindrical battery cells mentioned in the embodiments of the present application may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries or magnesium-ion batteries, etc., and the embodiments of the present application do not limit this. The cylindrical battery cells may be cylindrical, flat, rectangular or other shapes, etc., and the embodiments of the present application do not limit this. Cylindrical battery cells are generally divided into three types according to the packaging method: cylindrical cylindrical battery cells, square cylindrical battery cells and soft-pack cylindrical battery cells, and the embodiments of the present application do not limit this.

[0061] For example, a cylindrical battery cell may generally include a shell, a battery cell assembly and an electrolyte, wherein the shell is used to contain the battery cell assembly and the electrolyte, and the shell is provided with at least one positive electrode column and at least one negative electrode column. The battery cell assembly includes one or more electrode assemblies, and the electrode assembly is formed by stacking or winding a positive electrode sheet, a negative electrode sheet and a separator.

[0062] Among them, the positive electrode sheet can generally include a positive electrode current collector and a positive electrode active material layer, the positive electrode active material layer is directly or indirectly coated on the positive electrode current collector, the positive electrode current collector not coated with the positive electrode active material layer protrudes from the positive electrode current collector coated with the positive electrode active material layer, the positive electrode current collector not coated with the positive electrode active material layer serves as a positive electrode tab sheet, and a plurality of positive electrode tab sheets are stacked together and electrically connected to the positive electrode column. Exemplarily, the plurality of stacked positive electrode tab sheets can be directly welded to the positive electrode column to form an electrical connection; or, the battery cell assembly can also include a positive electrode adapter sheet, the plurality of stacked positive electrode tab sheets are welded to one end of the positive electrode adapter sheet, and the other end of the positive electrode adapter sheet is welded to the positive electrode column, so that the positive electrode tab sheet is electrically connected to the positive electrode column.

[0063] The negative electrode sheet can generally include a negative electrode current collector and a negative electrode active material layer, the negative electrode active material layer is directly or indirectly coated on the negative electrode current collector, the negative electrode current collector not coated with the negative electrode active material layer protrudes from the negative electrode current collector coated with the negative electrode active material layer, the negative electrode current collector not coated with the negative electrode active material layer serves as a negative electrode tab sheet, and a plurality of negative electrode tab sheets are stacked together and electrically connected to the negative electrode column. Exemplarily, a plurality of negative electrode tab sheets stacked together can be directly welded to the negative electrode column to form an electrical connection; or, the battery cell assembly can also include a negative electrode adapter sheet, a plurality of negative electrode tab sheets stacked together are welded to one end of the negative electrode adapter sheet, and the other end of the negative electrode adapter sheet is welded to the negative electrode column, so that the negative electrode tab sheet is electrically connected to the negative electrode column. The material of the separator is not limited, for example, it can be polypropylene or polyethylene.

[0064] At the same time, cylindrical battery cells mainly rely on the movement of metal ions between the positive electrode and the negative electrode to work. Taking lithium-ion batteries as an example, the material of the positive electrode current collector can be aluminum, the material of the positive electrode active material layer can be lithium cobalt oxide, lithium iron phosphate, ternary lithium or lithium manganese oxide, etc., the material of the negative electrode current collector can be copper, and the material of the negative electrode active material layer can be carbon or silicon, etc. During the charge and discharge process, Li+ is embedded and de-embedded back and forth between the two electrodes: when charging, Li+ is de-embedded from the positive electrode, embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.

[0069] In the automated production process of cylindrical batteries, when the cylindrical batteries are conveyed to the barcode scanning device 10, that is, the conveyed cylindrical battery cells 200 are at a position where multiple barcode scanners 14 are arranged at intervals along their circumference and the scanning ranges of the multiple barcode scanners 14 completely cover them in the circumference, the multiple barcode scanners 14 of the barcode scanning device 10 scan the identification codes on the cylindrical battery cells 200, and the cylindrical battery cells 200 continue to be conveyed along the conveying direction after passing through the barcode scanning device 10.

[0070] In this embodiment, the scanning range of multiple scanners 14 refers to the sum of the scanning ranges of the multiple scanners 14 respectively. The scanning range completely covers the cylindrical battery cell 200 in the circumferential direction of the cylindrical battery cell 200. Exemplarily, the scanning range can completely cover the identification code in the axial direction of the cylindrical battery cell 200.

[0071] In this embodiment, the multiple barcode scanners 14 are configured to be spaced apart along the circumference of the cylindrical battery cell 200. The multiple barcode scanners 14 can be spaced apart evenly or unevenly along the circumference of the cylindrical battery cell 200. The relative arrangement positions of the multiple barcode scanners 14 can be reasonably set as needed.

[0072] In the present embodiment, a plurality of code scanners 14 are arranged at intervals along the circumference of the cylindrical battery cell 200, and the scanning range of the plurality of code scanners 14 completely covers the cylindrical battery cell 200 in the circumferential direction of the cylindrical battery cell 200, so that the cylindrical battery cell 200 does not need to be rotated or the like, and the plurality of code scanners 14 can stably and reliably scan the identification code on the cylindrical battery cell 200, thereby greatly improving the scanning efficiency of the cylindrical battery cell, and the cylindrical battery cell 200 can maintain the original conveying speed for conveying through the code scanning device 10, so that the code scanning device 10 can well meet the needs of efficient production of the cylindrical battery cell 200 in automated production.

[0073] In this embodiment, the scanning device 10 also includes a conveying mechanism 15. During the process of conveying the cylindrical battery cells 200 on the automated production line, the cylindrical battery cells 200 are conveyed on the conveying line 20 in the automated conveying system 100 to various processes for processing, testing and other process operations. When the cylindrical battery cells 200 need to be scanned to continue to be conveyed downstream of the production line, the conveying mechanism 15 conveys the cylindrical battery cells 200 on the conveying line 20 to the scanning position, and multiple scanners 14 scan the cylindrical battery cells 200.

[0074] In this embodiment, the scanning device 10 is provided with a conveying mechanism 15 to convey the cylindrical battery cells 200 on the conveying line 20 to the scanning position for scanning. The structure is simple and can well meet the scanning needs of the cylindrical battery cells 200 on the automated production line.

[0075] In this embodiment, the conveying device includes a turntable 152, which is rotatable around a first axis. The turntable 152 is provided with one or more fixed grooves 1521 arranged at intervals along the circumference of the turntable 152, and the fixed grooves 1521 fix the cylindrical battery cells 200. Specifically, the cylindrical battery cells 200 are generally placed on the support cups 300 for conveying. The fixed grooves 1521 can fix the support cups 300 to convey and fix the cylindrical battery cells 200. When the turntable 152 conveys the cylindrical battery cells 200, the fixed grooves 1521 can take out and fix the cylindrical battery cells 200 on the conveying line 20. When the fixed grooves 1521 move to the scanning position with the rotation of the turntable 152, multiple scanners 14 scan the cylindrical battery cells 200.

[0076] Exemplarily, the turntable 152 can be configured to have multiple layers to increase the support and fixing range of the fixing groove 1521 in the first direction and improve the stability of the cylindrical battery cell 200 fixed in the fixing groove 1521. For example, the turntable 152 can be configured to have a two-layer structure, and the two fixing grooves 1521 cooperate with the fixing cup 300 to fix the cylindrical battery cell 200.

[0077] In this embodiment, a plurality of fixing grooves 1521 are arranged at intervals in the circumferential direction of the turntable 152 for fixing the cylindrical battery cells 200. The cylindrical battery cells 200 continuously conveyed on the conveyor line 20 can be transported by the turntable 152, and the distance between adjacent cylindrical battery cells 200 can be increased to a certain extent, thereby providing sufficient scanning space for the barcode scanner 14 to scan the barcode. In this way, the turntable 152 does not need to reduce the conveying speed to separate the plurality of cylindrical battery cells 200 continuously conveyed on the conveyor line 20 to meet the need of scanning the barcode. The turntable 152 can maintain a high-speed rotating conveying state, so that the conveying speed of the cylindrical battery cells 200 in the barcode scanning device 10 can be consistent with or faster than the conveying speed on the conveyor line 20, thereby effectively reducing the probability of a decrease in the conveying efficiency of the cylindrical battery cells 200 due to the barcode scanning process during the automated production and conveying process, so that the cylindrical battery cells 200 can maintain efficient automated production, so that the barcode scanning device 10 can well match the needs of efficient production of the cylindrical battery cells 200.

[0078] When multiple fixed grooves 1521 are set on the turntable 152, during the rotation of the turntable 152, the multiple fixed grooves 1521 can continuously take out the cylindrical battery cells 200 from the conveyor line 20 and convey them to the scanning position for scanning. Since the multiple scanners 14 completely cover the cylindrical battery cells 200, when the cylindrical battery cells 200 are rotated to the scanning position, the multiple scanners 14 can complete the scanning, and the turntable 152 can maintain the original rotation state and continue to rotate. The turntable 152 can continue to rotate to meet the continuous scanning needs of the multiple cylindrical battery cells 200 conveyed on the conveyor line 20.

[0079] In this embodiment, the conveying mechanism 15 is provided with a turntable 152, which rotates around the axis of the first direction and is provided with a fixing groove 1521 for fixing the cylindrical battery cell 200. The structure is simple, so that the turntable 152 can continuously convey the cylindrical battery cell 200 to the scanning position for scanning by rotating, thereby well meeting the scanning needs of the cylindrical battery cell 200 continuously conveyed on the conveying line 20, so that the scanning device 10 can meet the need for efficient scanning of a single cylindrical battery cell 200 while the scanning device 10 can well match the high-speed transportation of the cylindrical battery cell 200 on the conveying line 20, reduce the probability of the cylindrical battery cell 200 on the automated production line rotating or slowing down and stopping at the scanning device 10, and make the conveying efficiency drop, so that the cylindrical battery cell 200 can maintain the same high-speed conveying rhythm as on the conveying line 20 when passing through the scanning device 10, so that the scanning device 10 can better match the need for efficient production of the cylindrical battery cell 200 during automated production.

[0080] According to the scanning device 10 of the cylindrical battery cell 200 of the embodiment of the present application, a plurality of scanners 14 are provided, and the plurality of scanners 14 are configured to be arranged at intervals in the circumferential direction of the cylindrical battery cell 200 and the scanning range completely covers the cylindrical battery cell 200 in the circumferential direction of the cylindrical battery cell 200. The conveying mechanism 15 is provided with a turntable 152, and the turntable 152 is provided with one or a plurality of fixing grooves 1521 arranged at intervals in the circumferential direction of the turntable 152. The fixing grooves 1521 are configured to fix the cylindrical battery cell 200, so that when the scanning device 10 performs a scanning operation on the cylindrical battery cell 200, the cylindrical battery cell 200 does not need to be rotated or the like, thereby greatly improving the scanning efficiency of the scanning device 10, and the turntable 152 can continuously and efficiently convey the cylindrical battery cell 200 conveyed on the conveyor line 20 to the scanning position by rotation, so that the scanning device 10 can well match the needs of efficient production during the automated production of the cylindrical battery cell 200.

[0081] In some embodiments of the present application, the number of barcode scanners 14 may be greater than or equal to three.

[0082] In this embodiment, the number of the barcode scanners 14 is greater than or equal to 3. For example, the number of the barcode scanners 14 may be 3, 4, 5, 6, 7, 8, and so on.

[0083] In this embodiment, the number of the barcode scanners 14 is set to be greater than or equal to 3, so that the scanning range of the multiple barcode scanners 14 can stably and reliably completely cover the cylindrical battery cell 200 in the circumferential direction of the cylindrical battery cell 200, so that the barcode scanning device 10 can stably and reliably scan the identification code on the cylindrical battery cell 200, so that the barcode scanning device 10 can operate stably and reliably.

[0084] In one embodiment of the present application, the number of barcode scanners 14 may be less than or equal to 6.

[0085] In this embodiment, the number of the barcode scanners 14 is set to be less than or equal to 6. For example, the number of the barcode scanners 14 may be 6, 5, 4 or 3.

[0086] In the present embodiment, the number of the barcode scanners 14 is set to be less than or equal to 6, so that the barcode scanner 10 has a smaller number of barcode scanners 14, thereby making the cost of the barcode scanner 10 lower, and the number of parts is smaller, the overall structure size is smaller, and the scanning device is more convenient and flexible in layout.

[0087] In some embodiments of the present application, reference Figure 3 and Figure 5 As shown, a plurality of code scanners 14 may be evenly spaced apart along the circumference of the cylindrical battery cell 200 .

[0088] In this embodiment, multiple code scanners 14 are evenly spaced along the circumference of the cylindrical battery cell 200, that is, the distance between adjacent code scanners 14 in the circumference of the cylindrical battery cell 200 is the same, and the scanning range of each code scanner 14 in the circumference of the cylindrical battery cell 200 can also be the same for the coverage of the cylindrical battery cell 200.

[0089] In this embodiment, multiple code scanners 14 are evenly spaced apart along the circumference of the cylindrical battery cell 200, so that the scanning range of the multiple code scanners 14 can stably and reliably completely cover the cylindrical battery cell 200, so that the code scanning device 10 can stably scan the identification code on the cylindrical battery cell 200, and the evenly spaced arrangement can reduce the complexity of the arrangement, so that the multiple code scanners 14 can be installed and arranged more conveniently.

[0090] In some embodiments of the present application, reference Figure 3-Figure 5 As shown, in the circumferential direction of the cylindrical battery cell 200, the scanning ranges of two adjacent scanners 14 form an overlapping area on the circumferential side surface of the cylindrical battery cell 200, and the overlapping area can be configured to be larger than the size of the identification code on the cylindrical battery cell 200 along the circumferential direction of the cylindrical battery cell 200.

[0091] In this embodiment, the overlapping area formed by the scanning ranges of two adjacent barcode scanners 14 is larger than the size of the identification code along the circumference of the cylindrical battery cell 200. Then, in the circumference of the cylindrical battery cell 200, the identification code on the cylindrical battery cell 200 can always be completely within the scanning area of ​​any one of the multiple barcode scanners 14.

[0092] In this embodiment, the overlapping area formed by the scanning ranges of two adjacent scanners 14 is larger than the circumferential size of the identification code in the cylindrical battery cell 200, so that at least one of the multiple scanners 14 can scan the complete identification code, so that the scanning device 10 can stably obtain the complete identification code information, thereby meeting the use requirements of the scanning device 10.

[0093] In some embodiments of the present application, reference Figure 3-Figure 5 As shown, the barcode scanner 14 may have a scanning window, which is configured to be arranged toward the circumferential side surface of the cylindrical battery cell 200 .

[0094] In this embodiment, the scanning window of the barcode scanner 14 is arranged toward the peripheral surface of the cylindrical battery cell 200. When the barcode scanner 14 performs a scanning operation, the light used for scanning can be directly irradiated from the scanning window to the peripheral surface of the cylindrical battery cell 200 to scan the identification code on the cylindrical battery cell 200.

[0095] In this embodiment, the scanning window of the barcode scanner 14 is configured to be arranged toward the peripheral surface of the cylindrical battery cell 200. The structure is simple, so that the cylindrical battery cell 200 can be stably within the scanning range of the barcode scanner 14, so that the barcode scanner 14 can stably perform scanning operations, which well meets the use requirements of the barcode scanning device 10.

[0096] In one embodiment of the present application, reference Figure 2 As shown, the angle between the optical axis of the scanning window and the normal line of the surface of the cylindrical battery cell 200 may be greater than or equal to 0° and less than or equal to 10°.

[0097] In this embodiment, the angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200 is greater than or equal to 0° and less than or equal to 10°. For example, the angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200 can be 0°, 1°, 2°, 2.2°, 2.5°, 3°, 5°, 6°, 8°, 9°, 10°, etc.

[0098] In the present embodiment, the angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200 is set to be greater than or equal to 0° and less than or equal to 10°, so that there is a smaller angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200, so that the light emitted by the scanner 14 can be irradiated to the surface of the cylindrical battery cell 200 more directly, reducing the influence of reflection when the light is irradiated to the surface of the cylindrical battery cell 200, so that the scanner 14 can scan the identification code more stably and make the acquired identification code information more accurate.

[0099] In this embodiment, the angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200 is set to be greater than or equal to 0° and less than or equal to 10°, so that the relative position of the scanner 14 and the cylindrical battery cell 200 in the axial direction of the cylindrical battery cell 200 can be adjusted within a certain range, making the scanning device 10 more convenient and flexible during installation and arrangement.

[0100] In this embodiment, by setting the angle between the optical axis of the scanning window and the surface normal of the cylindrical battery cell 200 to be greater than or equal to 0° and less than or equal to 10°, the code scanning device 10 can obtain more accurate identification code information and is more flexible and convenient in layout.

[0101] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the code scanning device 10 may further include a mounting frame 13 , and a plurality of code scanners 14 are mounted on the mounting frame 13 .

[0102] In this embodiment, the barcode scanning device 10 is provided with a mounting frame 13, and multiple scanners are installed on the mounting frame 13. The structural dimensions of the mounting frame 13 can be flexibly set and adjusted according to the layout space, and the material of the mounting frame 13 can be reasonably selected according to the needs of installation and support and fixation, etc., to meet the support and fixation needs of the barcode scanner 14 and the assembly and layout needs on the automated production line.

[0103] In this embodiment, the code scanning device 10 is provided with a mounting frame 13 , and a plurality of code scanners 14 are mounted on the mounting frame 13 . The structure is simple, and the installation and fixation of the plurality of code scanners 14 are convenient, thus well meeting the assembly and use requirements of the code scanning device 10 .

[0104] In one embodiment of the present application, Figure 2 As shown, the mounting frame 13 may include a mounting seat 131, and the mounting seat 131 is configured to be aligned with the scanning position of the cylindrical battery cell 200 in a first direction (eg Figure 2 The plurality of barcode scanners 14 are arranged at intervals along the circumference of the mounting base 131 and fixed on the mounting base 131 , and the first direction is the axial direction of the cylindrical battery cell 200 .

[0105] In this embodiment, the mounting frame 13 includes a mounting seat 131, and the mounting seat 131 and the scanning position of the cylindrical battery cell 200 are arranged at intervals in the first direction. The scanning position of the cylindrical battery cell 200 may refer to the position where the cylindrical battery cell 200 needs to be scanned during the transportation process of the automated production line. After the cylindrical battery cell 200 passes through the scanning position in the conveying direction of the conveyor line 20 and is scanned, it continues to be transported downstream of the production line.

[0106] The mounting seat 131 and the code scanning position are arranged at intervals in the first direction, and the first direction is the axial direction of the cylindrical battery cell 200. Multiple code scanners 14 are arranged at intervals along the circumference of the mounting seat 131 and fixed on the mounting seat 131. After the multiple code scanners 14 are assembled to the mounting seat 131, the multiple code scanners 14 can be arranged at intervals in the circumference of the cylindrical battery cell 200.

[0107] In this embodiment, the mounting frame 13 is provided with a mounting seat 131, and multiple code scanners 14 are arranged at intervals along the circumference of the mounting seat 131 and fixed on the mounting seat 131. The structure is simple and the fixation is convenient. The mounting seat 131 is configured to be arranged at intervals with the scanning position of the cylindrical battery cell 200 in the first direction, so that the multiple code scanners 14 can be stably arranged on the circumference of the cylindrical battery cell 200 after being assembled with the mounting seat 131, thereby well meeting the arrangement requirements of the code scanner 14 and the cylindrical battery cell 200, making it more convenient to arrange the code scanning device 10 in the automated production line.

[0108] In some examples of this application, such as Figure 2 As shown, the mounting seat 131 may be formed with a plurality of side walls extending along the first direction, the plurality of side walls are arranged in one-to-one correspondence with the plurality of barcode scanners 14 , and the barcode scanners 14 are mounted on the corresponding side walls.

[0109] In this embodiment, the mounting seat 131 is formed with a plurality of side walls extending along the first direction, and the plurality of side walls are arranged one-to-one with the plurality of barcode scanners 14. For example, when three barcode scanners 14 are provided in the barcode scanning device 10, the mounting seat 131 may form three side walls correspondingly, and each scanner is installed on the corresponding side wall. When five barcode scanners 14 are provided in the barcode scanning device 10, the mounting seat 131 may form five side walls, and one barcode scanner 14 is installed on each of the five side walls. Exemplarily, the mounting seat 131 may be a block-shaped, pancake-shaped, or other structure, and the material of the mounting seat 131 may be metal or non-metal, as long as it meets the requirements of support and fixation, etc. For example, the mounting seat 131 may be an aluminum block.

[0110] In this embodiment, the mounting base 131 is provided with multiple side walls which are arranged in one-to-one correspondence with the multiple barcode scanners 14, and the structure is simple, which is convenient for the installation and fixation of the scanner. Since the relative position of each side wall in the circumferential direction of the mounting base 131 is fixed, the relative positions of the multiple barcode scanners 14 installed on each side wall in the circumferential direction of the mounting base 131 can also be relatively fixed. Therefore, after the multiple barcode scanners 14 are installed on the mounting base 131, less adjustments can be made to meet the arrangement requirements of the relative positions, thereby making the installation and arrangement of the multiple barcode scanners 14 in the barcode scanning device 10 more convenient and easy to a certain extent.

For example, the other end of the mounting plate 133 can extend to the circumferential outer side of the cylindrical battery cell 200 at the scanning position, so that the angle between the optical axis of the scanning window of the barcode scanner 14 and the normal line of the surface of the cylindrical battery cell 200 meets the assembly requirements. The mounting plate 133 and the mounting bracket 132 can be fixedly connected or detachably connected and fixed.

[0132] In some embodiments of the present application, Figure 1As shown, the conveying mechanism 15 may also include: a picking piece 151 and a unloading piece 153, wherein the picking piece 151 is configured to be suitable for transferring the cylindrical battery cells 200 located on the conveying line 20 of the cylindrical battery cells 200 to the fixed groove 1521 of the turntable 152; and the unloading piece 153 is configured to be suitable for transferring the cylindrical battery cells 200 in the fixed groove 1521 to the conveying line 20.

[0133] In this embodiment, the conveying mechanism 15 also includes a material picking piece 151 and a material unloading piece 153. When the cylindrical battery cell 200 is conveyed on the conveyor line 20, the material picking piece 151 transfers the cylindrical battery on the conveyor line 20 to the fixed groove 1521 of the turntable 152. The turntable 152 rotates, and when the cylindrical battery cell 200 follows the rotation of the turntable 152 and passes the code scanning position, multiple code scanners 14 cooperate to scan the code. After the cylindrical battery cell 200 is scanned, the material unloading piece 153 transfers the cylindrical battery cell 200 from the turntable 152 to the conveyor line 20, and the cylindrical battery continues to be conveyed to the downstream of the conveyor line 20.

[0134] In this embodiment, the conveying mechanism 15 is provided with a material picking component 151 and a material unloading component 153. The material picking component 151 cooperates with the material unloading component 153 to transfer the cylindrical battery cells 200 on the conveying line 20 to the turntable 152 and transfers them back to the conveying line 20 after scanning. The structure is simple and can well meet the scanning needs of the cylindrical battery cells 200 during the conveying process, so that the scanning device 10 can be well arranged on the automated production line to perform scanning operations.

[0135] In one embodiment of the present application, Figure 1 As shown, the material picking member 151 can be in the shape of a disk, and the material picking member 151 can rotate around a second axis extending along the first direction. One or multiple material picking grooves 1511 arranged at intervals along the circumference of the material picking member 151 are formed on the material picking member 151, and the material picking grooves 1511 are configured to be suitable for fixing cylindrical battery cells 200, wherein the conveying mechanism 15 is configured to transfer the cylindrical battery cells 200 in the material picking groove 1511 to the fixing groove 1521 when the material picking groove 1511 is docked with the fixing groove 1521.

[0136] In this embodiment, the material picking member 151 is in the shape of a disk and can rotate around a second axis extending along the first direction. One or more material picking troughs 1511 are formed on the material picking member 151. For example, the number of material picking troughs 1511 can be one, two, three, four, etc. The number of material picking troughs 1511 can be reasonably set according to needs. When the code scanning device 10 is running, the material picking member 151 rotates, and the material picking trough 1511 takes out the cylindrical battery cell 200 from the conveyor line 20. The material picking member 151 rotates to rotate the material picking trough 1511 to a position for cooperating with the turntable 152 for transportation. The cylindrical battery cell 200 in the material picking trough 1511 can be transferred to the fixed groove 1521 of the turntable 152. Exemplarily, the material picking member 151 can also be a multi-layer structure, so that the multiple material picking troughs 1511 cooperate in the first direction to have a more stable support effect on the cylindrical battery cell 200.

[0137] For example, magnets may be provided at the material taking trough 1511 and the fixing trough 1521 to magnetically fix the cup 300. At the transfer position, the magnetic force of the material taking trough 1511 on the cup 300 is removed, and the magnetic force of the fixing trough 1521 is applied to the cup 300, so that the cup 300 is separated from the material taking trough 1511 and fixed to the fixing trough 1521, thereby transferring the cylindrical battery cell 200. The rotation speed of the material taking member 151 and the turntable 152 can be reasonably set as needed, so that during the rotation of the material taking member 151 and the turntable 152, the cylindrical battery cell 200 of the material taking trough 1511 can be stably transferred to the fixing trough 1521 of the turntable 152.

[0138] In this embodiment, the material picking member 151 is set in a disk shape and can rotate around a second axis extending in the first direction. The material picking member 151 is provided with a material picking trough 1511, which has a simple structure and can cooperate well with the turntable 152 to transport the cylindrical battery cells 200, meeting the use needs of the code scanning device 10 on the automated production line of the cylindrical battery cells 200.

[0139] In one embodiment of the present application, Figure 1 As shown, the discharge member 153 can be in the shape of a disk, and the discharge member 153 can rotate around a third axis extending along the first direction. One or multiple discharge grooves 1531 arranged at intervals along the circumference of the discharge member 153 are formed on the discharge member 153, and the discharge grooves 1531 are configured to be suitable for fixing the cylindrical battery cells 200, wherein the conveying mechanism 15 is configured to transfer the cylindrical battery cells 200 in the fixing groove 1521 to the discharge groove 1531 when the discharge groove 1531 is docked with the fixing groove 1521.

[0140] In this embodiment, the discharge member 153 is in the shape of a disk and is rotatable around a third axis extending along the first direction. One or more discharge grooves 1531 are formed on the discharge member 153. For example, the number of discharge grooves 1531 can be one, two, three, four, etc. The number of discharge grooves 1531 can be reasonably set according to needs. When the barcode scanning device 10 is in operation, during the rotation of the discharge member 153, when the discharge groove 1531 rotates to a position for cooperating with the turntable 152 for transportation, the discharge groove 1531 takes out the cylindrical battery cell 200 from the turntable 152, and the cylindrical battery cell 200 in the fixed groove 1521 can be transferred to the fixed groove 1521 of the discharge member 153. The discharge member 153 can also be a multi-layer structure, so that the multiple discharge grooves 1531 cooperate with each other in the first direction to have a more stable supporting effect on the cylindrical battery cell 200.

[0141] Exemplarily, the discharge chute 1531 can be provided with a magnet to magnetically fix the cup 300. At the transfer position, the magnetic force on the cup 300 on the fixing chute 1521 is removed, and the magnetic force on the discharge chute 1531 is applied to the cup 300, so that the cup 300 is detached from the fixing chute 1521 and fixed to the discharge chute 1531, thereby transferring the cylindrical battery cell 200. When the discharge chute 1531 is rotated to a position cooperating with the conveyor line 20, the discharge chute 1531 can remove the magnetic attraction on the cup 300, and the cylindrical battery cell 200 is conveyed downstream under the conveying action of the conveyor line 20. The rotation speeds of the unloading piece 153, the turntable 152 and the picking piece 151 can be reasonably set as needed so that during the rotation of the unloading piece 153, the picking piece 151 and the turntable 152, the cylindrical battery cells 200 can be stably and efficiently transferred from the conveyor line 20 to the scanning position for scanning and then transferred back to the conveyor line 20.

[0142] In this embodiment, the unloading member 153 is set in a disc shape and is rotatable around a second axis extending in the first direction. The unloading member 153 is provided with a material picking trough 1511, which has a simple structure and can cooperate well with the turntable 152 to transport the cylindrical battery cells 200, meeting the use needs of the code scanning device 10 on the automated production line of the cylindrical battery cells 200. Since the turntable 152 drives the cylindrical battery cells 200 to rotate, the cylindrical battery cells 200 do not need to perform additional operations such as rotation when scanning the code. The turntable 152, the material picking member 151 and the unloading member 153 can transport the cylindrical battery cells 200 in a high-speed rotation manner, thereby better compensating for the time loss of the cylindrical battery cells 200 during the transportation process in the code scanning device 10. While improving the scanning efficiency of the code scanning device 10, the code scanning device 10 can well match the high-speed transportation of the cylindrical battery cells 200, thereby well meeting the needs of efficient production of the cylindrical battery cells 200.

[0143] In some embodiments of the present application, Figure 1 As shown, the scanning device 10 may further include: a rejection mechanism 16, which is arranged downstream of the scanning position in the direction in which the conveying mechanism 15 conveys the cylindrical battery, and the rejection mechanism 16 is communicatively connected with the scanner 14. The rejection mechanism 16 is configured to move the cylindrical battery cell 200 in the fixed groove 1521 out of the conveying mechanism 15 when the scanning result is abnormal.

[0144] In this embodiment, the barcode scanning device 10 is further provided with a rejection mechanism 16, which is arranged downstream of the barcode scanning position and is communicatively connected with the barcode scanner 14. The rejection mechanism 16 removes the cylindrical battery cell 200 from the conveying mechanism 15 when the barcode scanning result is abnormal. The barcode scanning result here is abnormal, for example, the barcode scanner 14 fails to scan the identification code, the cylindrical battery cell 200 scanned by the barcode scanner 14 is detected to have defects in the previous process and needs to be rejected, the information of the identification code on the cylindrical battery cell 200 does not match the information of the support cup 300 fixing it, etc. The rejection mechanism 16 removes the cylindrical battery cell 200 from the conveying mechanism 15. Exemplarily, the rejection mechanism 16 may include a rejection cylinder and a support frame for fixing the rejection cylinder, and the rejection cylinder operates to remove the cylindrical battery cell 200 in the fixed groove 1521 from the fixed groove 1521.

[0145] In this embodiment, the barcode scanning device 10 is provided with a rejection mechanism 16, which can cooperate with the barcode scanner 14 to reject abnormal cylindrical battery cells 200. The structure is simple and can well meet the need for automatically rejecting cylindrical battery cells 200 with scanning abnormalities during the automated production process of cylindrical battery cells 200.

[0146] In one example of this application, Figure 1 As shown, the code scanning device 10 may further include an adapter plate 154, which may rotate around a fourth axis extending along the first direction. The adapter plate 154 is provided with one or more adapter grooves 1541 arranged at intervals along the circumference of the adapter plate 154, and the adapter grooves 1541 may be configured to be suitable for fixing the cylindrical battery cells 200 rejected by the rejection mechanism 16.

[0147] In this embodiment, the adapter groove 1541 provided on the adapter plate 154 is used to fix the cylindrical battery cell 200 rejected by the rejection mechanism 16. When the rejection mechanism 16 rejects the cylindrical battery, the rejection cylinder of the rejection mechanism 16 pushes the cylindrical battery in the fixing groove 1521 to the adapter groove 1541. The adapter groove 1541 fixes the support cup 300 to fix the cylindrical battery cell 200. The adapter plate 154 rotates to move the cylindrical battery cell 200 to a position away from the rotating plate 152 for processing. The adapter can also be a multi-layer structure so that the multiple adapter grooves 1541 cooperate to have a more stable supporting effect on the cylindrical battery cell 200 in the first direction.

[0148] In this embodiment, the scanning device 10 is provided with a transfer plate 154 to cooperate with the rejection mechanism 16 to transfer the cylindrical battery cells 200. The structure is simple, so that the scanning device 10 can stably transfer the cylindrical battery cells 200 that need to be rejected during the continuous scanning process, so that the scanning device 10 can cooperate with the high-speed transportation of the continuous cylindrical battery cells 200 on the conveyor line 20 to perform stable and reliable scanning operations and convey the cylindrical battery cells 200.

The conveying mechanism 15 can be provided with a driving mechanism and a transmission mechanism to drive the rotation of the material picking piece 151, the turntable 152, the discharge piece 153 and the adapter plate 154.
