[0044] Description of some processes in the battery production process:

[0045] Paired stacking: In order to increase the battery capacity, the number of cells in the battery is increased to 2n (n ≥ 2); before the cells are installed in the shell of the single battery, the cells need to be paired and stacked according to certain standards. For ease of understanding, refer to Figure 10 As shown, taking the example of a single cell containing 4 battery cells, it is necessary to first perform tab welding on two battery cells (A battery cell and B battery cell) as a group, that is, according to the process requirements of battery cell production, if battery cell A and battery cell B are stacked in the default direction, the positive and negative pole positions of battery cell A and battery cell B will be exactly opposite. Therefore, it is necessary to flip either battery cell A or battery cell B 180 degrees. After flipping, stacking can make the positive and negative pole positions of battery cell A and battery cell B the same. Furthermore, due to the process requirements of battery cell production, the tabs of battery cell A and battery cell B should be as close as possible, and the distance between the two tabs between the stacked battery cells should be minimized (after stacking, the tabs of the battery cell on the lower layer should be on the upper side of the battery cell body, and the tabs of the battery cell on the upper layer should be on the lower side of the battery cell body). This stacking method facilitates more stable operation of the welding equipment during welding, improves the operating space and reliability of welding, and thereby improves the welding yield.

[0046] Applying bundling glue: After the battery cells are stacked, it is usually necessary to apply bundling glue to fix the position of the battery cells to prevent the battery cells from shifting during subsequent operations, which would affect the assembly accuracy and battery performance.

[0047] Ultrasonic pre-welding: In the process of connecting the battery cell tabs, ultrasonic welding is usually used to ensure the stability and reliability of the electrical connection. This welding method can fuse the metal surface through high-frequency vibration to form a stable solder joint, reducing resistance and heat loss.

[0048] Tab cutting: Before tab cutting, the tabs after welding are of different lengths. Based on this, the tabs need to be cut neatly. The tabs are the current lead-out terminals of the battery cell. In order to better match the structure and design requirements in the subsequent packaging process, the tabs need to be cut to ensure that their shape and length conform to the overall design of the battery.

[0049] In the related art, since the battery cell needs to be transferred between different processes (such as stacking, welding, cutting, etc.), the battery cell needs to be handled by mechanical clamps. However, multiple handling of the battery cell has potential risks, i.e., repeated clamping of the mechanical clamps can easily cause indentations, scratches or other mechanical damage to the surface of the battery cell, thereby affecting the appearance quality of the finished product, and even possibly damaging the internal structure of the battery cell. In the process of multiple handling and equipment contact, foreign matter (such as dust, tiny metal particles, etc.) can be mixed into the surface or interior of the battery cell, which can negatively affect the long-term safety and performance of the battery cell and increase the risk of battery failure.

[0050] Based on the above different processes (such as stacking, welding, cutting, etc.), different workstations or machines need to be arranged in the production workshop, which occupies the limited space in the production workshop, resulting in relatively high manufacturing cost of the battery. Especially for the pairing and stacking process of the battery cell, special equipment or machines are usually needed to complete the accurate turning, stacking and positioning of the battery cell, which results in a large amount of occupied space in the limited workshop, and due to the scattered arrangement of the process equipment, the distance between the process equipment increases, the internal logistics becomes complex, the handling, conveying and management of the battery cell become more difficult, and the time cost and labor cost of the production process are increased.

[0051] Therefore, in the specific embodiments of the present application, a pairing and rubber bonding pre-welding device is provided, which is used for Figures 1 to 9As shown, the pair of adhesive pre-welding equipment includes: a magnetic drive circulating line 1 for conveying the cell fixture, and a feeding mechanism 2, a binding adhesive applying mechanism 4, an ultrasonic pre-welding mechanism 5 and a discharging mechanism 7 arranged in sequence along the conveying direction of the magnetic drive circulating line 1. The magnetic drive circulating line 1 is slidably connected with a plurality of fixed jigs 101 for placing the cells, wherein the feeding mechanism 2, the binding adhesive applying mechanism 4, the ultrasonic pre-welding mechanism 5 and the discharging mechanism 7 arranged in sequence along the conveying direction of the magnetic drive circulating line 1 can effectively integrate the equipment required in each process, optimize the layout of each equipment in the production workshop, improve the space utilization, and at the same time, the feeding mechanism 2 carries the cells to the fixed jigs 101 on the magnetic drive circulating line 1, which can drive the cells to displace along the conveying direction of the magnetic drive circulating line 1 through the fixed jigs 101, so that the cells can be processed by the binding adhesive applying mechanism 4 and the ultrasonic pre-welding mechanism 5 in sequence, and finally the cells after processing are taken off from the fixed jigs 101 by the discharging mechanism 7 and transported to the designated area for storage, that is, the magnetic drive circulating line 1 fixes the cells on the jigs, and completes multiple processes at one time without the need for multiple handling. The magnetic drive circulating line 1 drives the cells to automatically flow through the steps of adhesive applying, pre-welding and cutting, which significantly simplifies the logistics path, and at the same time, by integrating multiple processes into one production line, the integrated equipment reduces the space occupation of each independent machine in the workshop, avoiding the large space required by the scattered arrangement of traditional multiple processes, and moreover, the cells do not need additional handling after entering the fixed jigs 101 of the magnetic drive circulating line 1, which greatly reduces the appearance damage and foreign matter pollution risk caused by multiple handling.

[0052] In some embodiments, with reference to Figure 1 As shown, it also includes a tab cutting mechanism 6 for cutting the welded tabs, after the tabs of the cells are welded, there are cases where the tabs are of different lengths, and the tabs need to be cut to size, wherein the tab cutting mechanism 6 is arranged between the ultrasonic pre-welding mechanism 5 and the discharging mechanism 7 along the conveying direction of the magnetic drive circulating line 1, and the tab cutting mechanism 6 is used to cut the tabs after being welded by the ultrasonic pre-welding mechanism 5. By cutting, the lengths of the tabs of different cells are adjusted to a uniform specification, thereby improving product quality and consistency, and the consistent length of the tabs can avoid jamming or adjustment due to size errors in subsequent assembly, improving the efficiency of automated assembly.

[0053] In some embodiments, with reference to Figure 2 and Figure 3As shown, the feeding mechanism 2 includes a feeding belt 201, a feeding carrying assembly 202, and a turnover assembly 203. The feeding belt 201 is used to transport the battery cell, and the number of the feeding belt 201 is two. The two feeding belts 201 are respectively used to transport different battery cells, and the polarities of the two kinds of battery cells are reversely arranged. Based on the needs of the production process, the tabs of the two stacked battery cells should be close to each other, and the polarities of the tabs of the two stacked battery cells should correspond to each other (positive tab to positive tab, and negative tab to negative tab). For the convenience of understanding, the two battery cells (A battery cell and B battery cell) shown in Figure 10 As shown, the feeding belt 201 is used to transport the A battery cell and the B battery cell, and each feeding belt 201 is provided with a corresponding feeding carrying assembly 202 to carry the battery cell to the fixing jig 101. When the A battery cell and the B battery cell are carried, they are carried by the corresponding feeding carrying assembly 202. The A battery cell and the B battery cell are carried to the fixing jig 101 by different feeding carrying assemblies 202. When the battery cell is carried by the feeding carrying assembly 202, one of the A battery cell and the B battery cell needs to be carried first. Taking the A battery cell as an example, which is located at the lower side of the stacked battery cell group, the A battery cell is placed on the fixing jig 101, and then the turnover assembly 203 is used to turn over the A battery cell by 180 degrees. Then, the fixing jig 101 is driven to move by the magnetic drive circulating line 1, so that the fixing jig 101 moves to the feeding carrying assembly 202 located downstream of the magnetic drive circulating line 1. The feeding carrying assembly 202 is used to carry the B battery cell. The B battery cell is carried to the fixing jig 101 by the feeding carrying assembly 202 located downstream of the magnetic drive circulating line 1 and is stacked on the A battery cell. At this time, the stacking of the two battery cells is completed.

[0054] In some embodiments, as shown in Figure 3 and Figure 4 As shown, the turnover assembly 203 ensures the polarity alignment when the battery cell is stacked, avoids the polarity error in the tab welding process, and improves the reliability and yield of the subsequent welding process. The two feeding belts 201 respectively transport different battery cells, and the turnover assembly 203 is used to turn over one of the battery cells. The turnover assembly 203 can flexibly cope with different stacking requirements, ensures the compatibility of the equipment for different battery cell combinations, and can be applied to the production of various battery cell specifications.

[0055] In some embodiments, as shown in Figure 7 The turnover assembly 203 includes a base, a lifting cylinder connected to the base, and a turnover clamp jaw. When the turnover operation of the battery cell is needed, the turnover clamp jaw first clamps the battery cell to be turned over. Then, the output rod of the lifting cylinder drives the turnover clamp jaw to be raised as a whole, so that the battery cell is separated from the fixing jig 101. Then, the turnover clamp jaw is driven to rotate to complete the turnover of the battery cell.

[0056] In some embodiments not shown, reference Figure 3 and Figure 4 The flipping assembly 203 shown includes a multi-axis robotic arm, that is, when the battery cells on the loading belt 201 are transported to the fixed fixture 101 by the multi-axis robotic arm, the battery cells can be flipped by the multi-axis robotic arm.

[0057] In some embodiments, reference Figures 1 to 3 As shown, the loading belt 201 includes a first pallet elevator 2011 and a first battery cell conveyor line 2012, wherein a tray for placing battery cells is provided on the first conveyor belt 20121 of the first battery cell conveyor line 2012. By carrying the battery cells on the tray, the battery cells can be effectively prevented from directly contacting the first conveyor belt 20121, causing unnecessary wear of the battery cells. There are two first battery cell conveyor lines 2012, and the first pallet elevator 2011 is placed between the two first battery cell conveyor lines 2012, and the conveying directions of the two first battery cell conveyor lines 2012 are both toward the first pallet elevator 2011, that is, the conveying directions of the first battery cell conveyor lines 2012 are both toward the first pallet elevator 2011.

[0058] Exemplary, reference Figure 2The first tray lifter 2011 and the first cell conveying line 2012 are shown in the middle. Four first tray lifters 2011 are arranged between two first cell conveying lines 2012, and each two first tray lifters 2011 correspond to one first cell conveying line 2012. The first tray lifter 2011 includes a frame body 20111 and a first conveying table 20112. The frame body 20111 is provided with a driving assembly that can drive the first conveying table 20112 to move along the height direction of the frame body 20111, so that the first conveying table 20112 is switched to a first position or a second position. Meanwhile, the first cell conveying line 2012 further includes a second conveying belt 20122 located below a first conveying belt 20121, and the conveying direction of the first conveying belt 20121 is opposite to that of the second conveying belt 20122. When the first conveying table 20112 is located at the first position, the upper surface of the first conveying table 20112 is coplanar with the upper surface of the first conveying belt 20121. When the first conveying table 20112 is located at the second position, the upper surface of the first conveying table 20112 is coplanar with the upper surface of the second conveying belt 20122. That is, when the tray carrying the cells is conveyed to the first conveying table 20112 by the first conveying belt 20121, the first conveying table 20112 is at the first position. The cells on the tray can be extracted and conveyed to the fixing jig 101 by the feeding and conveying assembly 202. After the conveying is completed, the tray is an empty tray. Under the driving of the driving assembly, the first conveying table 20112 moves downward together with the empty tray, and the switching from the first position to the second position is completed. At this time, the upper surface of the first conveying table 20112 is coplanar with the upper surface of the second conveying belt 20122. The empty tray is conveyed out by the second conveying belt 20122 and is recycled.

[0059] In some unillustrated embodiments, the empty tray conveyed out by the second conveying belt 20122 can be placed on the second conveying belt 20122 again by a mechanical hand and the cells are placed on the empty tray; or the first tray lifter 2011 is arranged at both ends of the first cell conveying line 2012, so as to complete the circulation of the empty tray. That is, when the tray carrying the cells reaches one of the first tray lifters 2011 by the first conveying belt 20121, the cells are extracted by the feeding and conveying assembly 202, and then the empty tray is switched from the first position to the second position. Then the empty tray is conveyed to the other first tray lifter 2011 by the second conveying belt 20122, so that the empty tray is switched from the second position to the first position. After that, the cells are placed on the empty tray again, and the tray carrying the cells is conveyed again by the first conveying belt 20121.

[0060] In some embodiments, in order to improve production efficiency, one first tray lifting machine 2011 corresponds to one first battery cell conveying line 2012, and the tray with the battery cell can be conveyed to the first conveying table 20112 of the first tray lifting machine 2011 through the first battery cell conveying line 2012. In order to improve the control effect of the tray with the battery cell, the end of the first conveying table 20112 away from the first battery cell conveying line 2012 is provided with a stop component 3. The stop component 3 includes a stop body and a stop piece. The stop piece is movably connected to the stop body in the height direction of the frame body 20111. The stop of the stop piece is controlled by the stop body to realize the blocking of the tray. The stop component 3 can select a pneumatic cylinder. The stop body is the cylinder body, and the stop piece is the cylinder output rod.

[0061] In some embodiments, as shown in Figure 2 、 Figure 6 and Figure 9 , the number of first battery cell conveying lines 2012 is two, the number of first tray lifting machines 2011 is at least two and is adjacent to each other, and each first tray lifting machine 2011 corresponds to an upper loading and carrying assembly 202. The conveying direction of the two first battery cell conveying lines 2012 is towards the first tray lifting machine 2011, so that the battery cell conveyed can be transported to the first tray lifting machine 2011, and then the battery cell on the first conveying table 20112 is carried to the fixed jig 101 on the magnetic drive circulating line 1 by the upper loading and carrying assembly 202.

[0062] In some embodiments, as shown in Figure 2 and Figure 8 , when the stop piece is in the stop position, the first tray lifting machine 2011 provides the battery cell to the corresponding upper loading and carrying assembly 202; when the stop piece leaves the stop position, the tray can flow between the adjacent at least two first conveying tables 20112.

[0063] For example, two first tray lifting machines 2011 correspond to two first battery cell conveying lines 2012. Each first tray lifting machine 2011 has a corresponding first battery cell conveying line 2012. When the two first battery cell conveying lines 2012 can normally convey the battery cell to the first conveying table 20112 of the corresponding first tray lifting machine 2011, the stop pieces of the stop components 3 installed on the two first tray lifting machines 2011 are in the stop position. The stop piece in the stop position can stop the tray with the battery cell transported to the first conveying table 20112, so as to prevent the tray with the battery cell from flowing to the adjacent another first tray lifting machine 2011.

[0064] For example, if one of the first battery cell conveying lines 2012 fails and the battery cells cannot be normally conveyed to the corresponding first pallet elevator 2011, the stop assembly 3 can be driven to make the stop member leave the stop position. The stop member no longer stops the pallet with the battery cells placed thereon, and the pallet with the battery cells placed thereon can flow to another adjacent first pallet elevator 2011.

[0065] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, it also includes a code scanning component 8, wherein the code scanning component 8 is used to scan the battery cell for inspection, wherein each battery cell is usually given a unique QR code or barcode during the production process. By scanning the code by the code scanning component 8, the production data of the battery cell can be bound to the unique identifier. If a problem occurs in the finished battery or battery module, the corresponding battery cell source, production batch, and production conditions can be found through the traceability system to achieve full process traceability. At the same time, the code scanning component 8 can automatically record information such as entry time, process parameters, processing results, etc. when the battery cell enters different processes (such as loading, gluing, welding, cutting, etc.). These data can be directly uploaded to the production management system (MES system) to achieve real-time production data recording and management, which is convenient for subsequent data analysis and process optimization, and the code scanning component 8 can be used to verify the type, batch and specification of the battery cell to ensure that the battery cell entering the production line matches the process requirements. For example, in processes such as stacking and gluing, the code scanning component 8 can verify whether the battery cell meets specific production standards, thereby avoiding process problems caused by feeding errors.

[0066] The scanning code assembly 8 is arranged at one end of the first battery cell conveying line 2012 away from the first tray elevator 2011. The scanning code assembly 8 includes a second battery cell conveying line 801, a mounting frame 802, a scanning code device 803, and a scanning code table 804. The mounting frame 802 is arranged between the first battery cell conveying line 2012 and the second battery cell conveying line 801. The scanning code assembly 8 includes the second battery cell conveying line 801, the mounting frame 802, the scanning code device 803, and the scanning code table 804. The mounting frame 802 is arranged between the first battery cell conveying line 2012 and the second battery cell conveying line 801. The mounting frame 802 is provided with a driver 901 for driving the scanning code table 804 to move, so that the scanning code table 804 is switched to a third position or a fourth position.
