Description

Technical Field

[0001] This utility model relates to the field of battery equipment technology, and in particular to a cutting and stacking integrated machine. Background Technology

[0002] In conventional cell stacking processes, after stacking, QR code tape is typically affixed to the cell surface. This QR code is used to bind processing data from subsequent hot-pressing processes, enabling data traceability throughout the cell manufacturing process. However, this traceability method cannot link the processing data of the multiple electrodes that make up the cell to the cell's QR code. When an anomaly occurs in one of the electrodes, it is difficult to quickly pinpoint the source of the problem, affecting anomaly analysis and process optimization. Furthermore, when battery performance or safety issues arise, it is necessary to retrieve additional batch data from the electrode production for manual comparison and analysis, which is not only time-consuming and labor-intensive but may also lead to inaccurate analysis results due to scattered or incomplete data records.

[0023] Please see Figures 1 to 5 In one embodiment of the present invention, the integrated cutting and stacking machine 10 includes a sheet-making device 100, a sheet-stacking device 200, and a feeding device 300.

[0024] The electrode fabrication apparatus 100 can prepare electrode sheets 30 using electrode strip 20. The electrode strip 20 is divided into positive electrode strip and negative electrode strip, so the prepared electrode sheets 30 are divided into positive electrode sheets 31 and negative electrode sheets 32. Specifically, there are two electrode fabrication apparatuses 100. One electrode fabrication apparatus 100 can prepare positive electrode sheets 31 using positive electrode strip, while the other electrode fabrication apparatus 100 can prepare negative electrode sheets 32 using negative electrode strip.

[0025] Please refer to it again. Figure 2 and Figure 3 The film-making apparatus 100 includes a first coding mechanism 110 and a first scanning mechanism 120. The first coding mechanism 110 forms a first identification code 301 on each of the manufactured electrodes 30, and the first scanning mechanism 120 identifies the first identification code 301 on the electrode 30. Specifically, in this embodiment, the first coding mechanism 110 includes a laser engraver (not shown), which engraves the first identification code 301 on the electrode 30. That is, the first coding mechanism 110 uses laser engraving to form the first identification code 301 on the electrode 30. Laser engraving is fast, matching the high-speed film-making cycle of the film-making apparatus 100. Moreover, the first identification code 301 formed by laser engraving is less prone to fading.

[0026] It should be noted that in other embodiments, the first identification code 301 can also be formed on the electrode 30 by means of ink printing or by affixing tape with a barcode.

[0027] The first identification code 301 is generally formed in the root region of the electrode tab 21 near the coating area of ​​the electrode 30, which avoids the ultrasonic welding area and the cutting area. More specifically, the first identification code 301 can be a barcode or a QR code.

[0028] The electrode fabrication apparatus 100 generally includes a strip unwinding mechanism 170, a strip correction mechanism (not shown in the figure), and an electrode tab positioning mechanism 180. The strip unwinding mechanism 170 unwinds the electrode strip 20. The strip correction mechanism corrects the deviation of the unwound electrode strip 20. After correction, the electrode strip 20 passes through the electrode tab positioning mechanism 180, which detects and positions the electrode tab 21 on the electrode strip 20. Then, the first coding mechanism 110 forms a first identification code 301 on the electrode tab 21. A first scanning mechanism 120 can also be provided downstream of the first coding mechanism 110 to confirm whether the first identification code 301 on the electrode strip 20 is properly engraved.

[0029] In addition, the electrode processing device 100 is provided with an electrode processing station on the downstream side of the first coding mechanism 110, and each electrode processing station is provided with a first scanning mechanism 120. The first scanning mechanism 120 can identify the first identification code 301 on the electrode 30 passing through the corresponding electrode processing station.

[0030] There are generally multiple electrode processing stations, and each station can perform corresponding operations. After the electrode strip 20 is engraved with the first identification code 301 by the first coding mechanism 110, it can sequentially pass through the downstream electrode processing stations and obtain the required electrode 30 after corresponding operations. When the electrode 30 passes through each electrode processing station, the corresponding first scanning mechanism 120 can identify the first identification code 301 on the electrode, thereby associating the processing data of each electrode 30 with the first identification code 301.

[0031] Specifically, in this embodiment, the electrode making device 100 also includes a rounded corner cutting mechanism 130, an electrode cutting mechanism 140, an electrode size detection mechanism 150, and an electrode defect detection mechanism 160, which are arranged sequentially at multiple electrode processing stations.

[0032] The rounded corner cutting mechanism 130 can perform rounded corner cutting on the electrode strip 20, and then the electrode cutting mechanism 140 cuts the electrode strip 20 to obtain multiple electrodes 30 in sequence. Next, the electrodes 30 pass through the electrode size detection mechanism 150 and the electrode defect detection mechanism 160 in sequence, so that the size of the electrode 20 can be measured and the presence of defects in the electrode 30 can be detected. It can be seen that before the electrode strip 20 is cut into electrodes 30, the first coding mechanism 110 can form a first identification code 301 on the electrode tab 21.

[0033] When the electrode strip 20 and electrode 30 pass through the rounded corner cutting mechanism 130, electrode cutting mechanism 140, electrode size detection mechanism 150 and electrode defect detection mechanism 160, the first barcode scanning mechanism 120 in the corresponding station first scans the first identification code 301 of the electrode 30, so that the rounded corner cutting data, electrode cutting data, size measurement data and defect detection data can be associated with the current electrode 30.

[0034] Specifically, the cutting and stacking integrated machine 10 generally also includes a control system (not shown in the figure). This control system is communicatively connected to the rounded corner cutting mechanism 130, the electrode cutting mechanism 140, the electrode size detection mechanism 150, the electrode defect detection mechanism 160, and each of the first barcode scanning mechanisms 120. The first barcode scanning mechanism 120 can upload the identified barcode information to the control system, while the rounded corner cutting data, electrode cutting data, size measurement data, and defect detection data generated by the rounded corner cutting mechanism 130, the electrode cutting mechanism 140, the electrode size detection mechanism 150, and the electrode defect detection mechanism 160 can also be uploaded to the control system. The control system can store the above-mentioned various electrode processing data with the corresponding barcode information, thereby realizing the association between the above-mentioned electrode processing data and the corresponding electrode 30.

[0035] Furthermore, in this embodiment, the electrode defect detection mechanism 160 includes a first conveyor belt 161, a second conveyor belt 162, a front detection component 163, and a back detection component 164. The bearing surface of the first conveyor belt 161 faces upwards, the bearing surface of the second conveyor belt 162 faces downwards, and the first conveyor belt 161 and the second conveyor belt 162 are connected. The front detection component 163 is disposed above the bearing surface of the first conveyor belt 161, and the back detection component 164 is disposed below the bearing surface of the second conveyor belt 162.

[0036] The first conveyor belt 161 and the second conveyor belt 162 can be vacuum belts, capable of adsorbing the electrode sheets 30 they carry. The first conveyor belt 161 and the second conveyor belt 162 overlap at their beginning and end, and their bearing surfaces are arranged opposite each other. The cut electrode sheets 30 are first carried by the first conveyor belt 161 and conveyed to the second conveyor belt 162. When the electrode sheet 30 is conveyed to the end of the first conveyor belt 161, its front side (i.e., the upper surface) can be adsorbed by the second conveyor belt 162, thereby transferring the electrode sheet 30 to the second conveyor belt 162 and continuing to convey it along the second conveyor belt 162. On the first conveyor belt 161, the back side (lower surface) of the electrode sheet 30 is in contact with the bearing surface, and its front side is facing upward and exposed, so the front detection component 163 can perform defect detection on the front side of the electrode sheet 30. When the electrode 30 is transferred to the second conveyor belt 162, the front side of the electrode 30 is attracted by the bearing surface of the second conveyor belt 162, while the back side is exposed downwards. Therefore, the back side detection component 164 can perform defect detection on the back side of the electrode 30.

[0037] The aforementioned electrode defect detection mechanism 160 does not require flipping the electrode 30 during the defect detection process, and the electrode 30 is detected during the transportation process, thereby simplifying the detection steps and significantly improving the detection efficiency.

[0038] In addition, the first conveyor belt 161 can extend below the electrode size detection mechanism 150. During the process of the electrode 30 being conveyed by the first conveyor belt 161, the electrode size detection mechanism 150 can also measure the size of the electrode 30.

[0039] Furthermore, in this embodiment, the electrode defect detection mechanism 160 also includes a waste recycling mechanism 165, which is disposed below the bearing surface of the second conveyor belt 162. When a defect in the size or appearance of the electrode 30 is detected, and the defective electrode 30 passes over the waste recycling mechanism 165, the second conveyor belt 162 can release the electrode 30, thereby causing the defective electrode 30 to fall into the waste recycling mechanism 165 for recycling.

[0040] Moreover, since the electrode 30 is upside down on the second conveyor belt 162, the second conveyor belt 162 only needs to remove the negative pressure in the area where the electrode 30 is located, so that the defective electrode 30 can automatically fall into the waste recycling mechanism 165 under the action of gravity, thereby quickly completing the waste removal.

[0041] Please refer to it again. Figure 4 The stacking apparatus 200 includes a stacking stage 210 and a second scanning mechanism 220. The stacking apparatus 200 has a stacking station, where the second scanning mechanism 220 and the stacking stage 210 are installed. The stacking apparatus 200 can acquire the positive electrode 31 and negative electrode 32 produced by the wafer fabrication apparatus 100, and move the positive electrode 31 and negative electrode 32 into the stacking station and alternately stack them on the stacking stage 210 to produce a battery cell 40. The second scanning mechanism 220 can adopt the same structure as the first scanning mechanism 120. Furthermore, the second scanning mechanism 220 can identify the first identification code 301 of the electrode 30 on the stacking stage 210. Thus, each electrode 30 constituting the battery cell 40 will be identified and recorded by the second scanning mechanism 220.

[0042] After the stacking is completed, the unloading device 300 can remove the stacked cells 40 from the stacking station. Further, the unloading device 300 also includes a second coding mechanism 310, which can form a second identification code (not shown) on the surface of the cell. Specifically, in this embodiment, the second coding mechanism 310 can attach an adhesive tape 41 containing the second identification code to the surface of the cell 40. The second identification code can be pre-printed on the adhesive tape 41 with ink, and then the second coding mechanism 310 attaches the entire tape 41 to the surface of the cell 40. By using an adhesive method to assign the second identification code to the cell 40, there is no need for engraving operations on the surface of the cell 40, thereby avoiding damage to the cell 40.

[0043] The second coding mechanism 310 and each of the second coding mechanisms 310 are also communicatively connected to the aforementioned control system. The second identification code corresponding to each cell 40 can be pre-generated and stored in the control system before the current cell 40 begins stacking. After stacking begins, the second scanning mechanism 220 stores the scanning information corresponding to the second identification code for each first identification code 301 it identifies, until the current cell 40 is stacked. In this way, the second identification code of the current cell 40 can be bound to the first identification code 301 of each electrode 30 constituting the current cell 40. By binding the second identification code to the first identification code 301 of each electrode 30 constituting the current cell 40, not only can the subsequent processing data for that cell 40 be traced, but also the processing data for each electrode 30 in that cell 40 can be traced, thus significantly improving the traceability of the cell manufacturing process.

[0044] In this embodiment, a positive electrode correction station and a negative electrode correction station are respectively provided on both sides of the lamination station. The positive electrode correction station and the negative electrode correction station are respectively provided with a positive electrode correction mechanism 230 and a negative electrode correction mechanism 240. Moreover, both the positive electrode correction station and the negative electrode correction station are provided with a second barcode scanning mechanism 220, which can identify the first identification code 301 on the electrode 30 that enters the positive electrode correction station or the negative electrode correction station.

[0045] The positive electrode correction mechanism 230 and the negative electrode correction mechanism 240 can adopt the same structure, which can drive the supported electrode 30 to adjust its angle or orientation, thereby achieving correction. The positive electrode correction mechanism 230 and the negative electrode correction mechanism 240 generally adopt the structure commonly used in the prior art, so they will not be described in detail here.

[0046] The positive electrode sheet 31, conveyed to the stacking device 200, is first transferred to the positive electrode correction mechanism 230. The second scanning mechanism 220 at the positive electrode correction station identifies the first identification code 301 on the current positive electrode sheet 31 and binds the correction and inspection data to the first identification code 301 after the correction and re-inspection of the positive electrode sheet 31. Similarly, the negative electrode sheet 32, conveyed to the stacking device 200, is first transferred to the negative electrode correction mechanism 240. The second scanning mechanism 220 at the negative electrode correction station identifies the first identification code 301 on the current negative electrode sheet 32 ​​and binds the correction and inspection data to the first identification code 301 after the correction and re-inspection of the negative electrode sheet 32. Finally, the corrected positive electrode sheet 31 and negative electrode sheet 32 ​​are alternately placed on the stacking table 210 to complete the stacking, which also helps to improve the stacking accuracy.

[0047] Furthermore, in this embodiment, the stacking device 200 also includes a positive electrode conveying mechanism 250 and a negative electrode conveying mechanism 260, wherein the positive electrode conveying mechanism 250 is disposed on the side of the positive electrode correction mechanism 230 facing away from the stacking stage 210, and the negative electrode conveying mechanism 260 is disposed on the side of the negative electrode correction mechanism 240 facing away from the stacking stage 210.

[0048] Both the positive electrode conveying mechanism 250 and the negative electrode conveying mechanism 260 can be in the form of conveyor belts. The positive electrode conveying mechanism 250 and the negative electrode conveying mechanism 260 are respectively connected to the wafer-making apparatus 100 for preparing positive electrode sheets 31 and negative electrode sheets 32. The prepared positive electrode sheets 31 and negative electrode sheets 32 are conveyed by the positive electrode conveying mechanism 250 and the negative electrode conveying mechanism 260 to one side of the positive electrode correction mechanism 230 and the negative electrode correction mechanism 240, respectively, for easy handling. In this way, the prepared positive electrode sheets 31 and negative electrode sheets 32 can be automatically and continuously conveyed to the stacking table 210, improving the automation level of the equipment.

[0049] In addition, in this embodiment, the stacking device 200 also includes a diaphragm unwinding mechanism 270, which can provide diaphragm strip 50 to the stacking table 210 and lay the diaphragm strip 50 in a Z-shape on the stacking table 210.

[0050] The diaphragm unwinding mechanism 270 typically drives the diaphragm strip 50 to oscillate back and forth, thereby enabling the diaphragm strip 50 to be laid in a Z-shape on the stacking table 210. Specifically, each time an electrode 30 is placed on the stacking table 210, the diaphragm strip 50 oscillates once. In this way, adjacent electrode 30s are separated by the diaphragm 50. Moreover, the diaphragm strip 50 performs Z-shaped laying at a relatively fast speed, which also helps to improve the stacking efficiency.

[0051] After being unloaded from the stacking table 210, the battery cell 40 generally needs to undergo several processing steps to ensure that it meets the process requirements. Specifically, in this embodiment, at least one of the following is provided on the downstream side of the unloading device 300: an adhesive application station, a hot pressing station, a testing and thickness measurement station, a weighing station, and a visual inspection station. The battery cell 40 can be adhesive-applied after entering the adhesive application station, hot-pressed after entering the hot pressing station, subjected to voltage testing and thickness measurement after entering the testing and thickness measurement station, weighed after entering the weighing station, and inspected for visual defects after entering the visual inspection station.

[0052] For more details, please refer to the following document. Figure 5 The device includes an adhesive application station equipped with an adhesive application device 400, a hot pressing station equipped with a hot pressing device 500, a testing and thickness measurement station equipped with a Hi-pot and a thickness measurement device 600, a weighing station equipped with a weighing device 700, and an appearance inspection station equipped with an appearance inspection device 800. In this embodiment, the battery cell 40 transferred by the unloading device 300 will sequentially pass through the adhesive application station, the hot pressing station, the testing and thickness measurement station, the weighing station, and the appearance inspection station.

[0053] Furthermore, the adhesive application station, hot pressing station, thickness testing station, weighing station, and appearance inspection station are all equipped with a third barcode scanning mechanism 900, which can identify the second identification code on the passing battery cell 40.

[0054] The third scanning mechanism 900 can also adopt the same structure as the first scanning mechanism 120 and the second scanning mechanism 220. The third scanning mechanism 900 is also connected to the control system, and the adhesive application device 400, hot pressing device 500, Hi-pot and thickness measuring device 600, weighing device 700 and appearance inspection device 800 are also connected to the control system. When the battery cell 40 passes through the adhesive application station, hot pressing station, thickness measuring station, weighing station and appearance inspection station, the third scanning mechanism 900 in the corresponding station can first identify the second identification code on the current battery cell 40, so that the adhesive application data, hot pressing data, voltage test and thickness detection, weighing data and appearance inspection data of the battery cell 40 can be associated with the current battery cell 40.

[0055] In the aforementioned integrated cutting and stacking machine 10, during the wafer fabrication process, the first coding mechanism 110 first forms a first identification code 301 on each electrode 30. As the electrode 30 passes through each electrode processing station, the corresponding first scanning mechanism 120 identifies the first identification code 301 on the electrode 30, thereby associating the processing data of each electrode 30 with the current electrode 30. During the stacking process, the second scanning mechanism 220 identifies the first identification code 301 of each electrode 30 constituting the battery cell 40. After stacking is completed, the unloading device 300 acquires the battery cell 40 from the stacking station, and the second coding mechanism 310 forms a second identification code on the surface of the battery cell 40. By binding the second identification code with the first identification code 301 of each electrode 30 constituting the cell 40, the cell 40 can be associated with all the electrodes 30 constituting the cell 40. This not only allows for the traceability of subsequent processing data for the cell 40, but also the traceability of processing data for each electrode 30 in the cell 40, thus significantly improving the traceability of the cell manufacturing process.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
