Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

[0030] The adaptive cutting adjustment system includes two cutting components, and the distance between the two cutting components needs to be adjusted for different electrode models. In related technologies, the distance between the two cutting components needs to be adjusted manually multiple times, which results in a significant amount of time being spent repeatedly adjusting the distance between the two cutting components during electrode changeover.

[0031] like Figure 1 As shown, an embodiment of this application provides a cutting adaptive adjustment system 100, which includes a cutting mechanism 1, a detection mechanism 2, and an adjustment mechanism 3. The cutting adaptive adjustment system 100 is suitable for cutting strip-shaped electrode sheets or diaphragms so that the cut electrode sheets have suitable forming dimensions. The electrode sheets can be positive electrode sheets or negative electrode sheets.

[0032] refer to Figures 1 to 3 The cutting mechanism 1 includes two rollers, two cutting elements 10, and a mounting bracket 13. The two rollers include a first roller 11 and a second roller 12. The two cutting elements 10 include a first cutting element 101 and a second cutting element 102. The first cutting element 101 is connected to the first roller 11 and is configured as an annular blade protruding relative to the first roller 11. The second cutting element 102 is connected to the second roller 12 and is configured as an annular blade flush with the second roller 12. The first roller 11 and the second roller 12 are arranged opposite each other, with a gap between them. The electrode sheet is sandwiched between the first roller 11 and the second roller 12. The first cutting element 101 and the second cutting element 102 are staggered along the length of the first roller 11 or the second roller 12, and there is a suitable gap between them, thereby cutting the electrode sheet.

[0033] The detection mechanism 2 is set to detect the interval between the two cut pieces 10.

[0034] The adjustment mechanism 3 is configured to adjust the interval between the two cut pieces 10 according to the interval detected by the detection mechanism 2.

[0035] By setting up a detection mechanism 2 to detect the gap between the two cut pieces 10, and adjusting mechanism 3 adjusting the gap between the two cut pieces 10 according to the gap detected by detection mechanism 2, the time required to adjust the gap between the two cut pieces 10 during electrode or diaphragm replacement can be effectively shortened, thereby improving production efficiency. Simultaneously, during maintenance of the cutting adaptive adjustment system 100, the aforementioned cutting adaptive adjustment system 100 can also improve maintenance efficiency. Furthermore, through the detection by detection mechanism 2, the adjusting mechanism 3 can precisely adjust the two cut pieces 10 to a suitable gap, resulting in better quality of the cut electrode and preventing burrs on the cut electrode caused by an unsuitable gap between the two cut pieces 10, which could lead to short circuits between the cut electrode and the diaphragm in the core package formed by hot rolling bonding.

[0036] Continue to refer to Figures 1 to 3In some embodiments, the detection mechanism 2 includes a signal transmitter 21 and a signal receiver 22. The signal transmitter 21 is configured to transmit signals, and the signal receiver 22 is configured to receive signals. The first guide roller 11 and the second guide roller 12 are spaced apart along the height direction of the cutting adaptive adjustment system 100. The signal transmitter 21 and the signal receiver 22 are located on both sides of the two cutting pieces 10. The two cutting pieces 10 can block at least part of the signal emitted by the signal transmitter 21 and project it into the signal receiver 22.

[0037] The signal transmitter 21 can be a light source transmitter that emits a parallel light beam, and the signal receiver 22 is configured to receive the light beam signal. The first cutter 101 and the second cutter 102 partially block the light source signal emitted by the signal transmitter 21 and project it into the signal receiver 22. By converting the changes in the emitted and received light source signals with the imaging size information of the first cutter 101 and the second cutter 10, the interval data between the two cutters 10 can be obtained.

[0038] Before actually measuring the interval between the two cut pieces 10, it is necessary to measure the standard piece and calibrate the measurement data of the measuring mechanism to improve the accuracy of the measurement data.

[0039] In some embodiments, such as Figure 1 As shown, the signal transmitter 21 and the signal receiver 22 are installed on the same horizontal plane so that the signal transmitter 21 and the signal receiver 22 are at the same horizontal height. During the transmission of the light source signal, the interference caused by the difference in installation height between the signal transmitter 21 and the signal receiver 22 on the measurement of the interval between the two cut pieces 10 is reduced.

[0040] like Figure 1 and Figure 3 As shown, the cutting adaptive adjustment system 100 also includes a base plate 23, a first fixed platform 24, and a second fixed platform 25. The first fixed platform 24 and the second fixed platform 25 are respectively connected to the two sides of the base plate 23, and the mounting bracket 13 is connected to the middle of the base plate 23. The signal transmitter 21 is fixed on the first fixed platform 24, and the signal receiver 22 is fixed on the second fixed platform 25. The height of the first fixed platform 24 is the same as the height of the second fixed platform 25, so that the signal transmitter 21 fixed on the first fixed platform 24 and the signal receiver 22 fixed on the second fixed platform 25 are mounted on the same horizontal plane.

[0041] In some embodiments, the signal transmitter 21 has a signal transmitting area 26, and the signal receiver 22 has a signal receiving area 27. The signal transmitting area 26 and the signal receiving area 27 are arranged opposite each other, and the area of ​​the signal transmitting area 26 is the same as the area of ​​the signal receiving area 27. This ensures that the portion of the light source signal emitted by the signal transmitter 21 that is not blocked by the two cutting pieces 10 and the two rollers can be completely received by the signal receiver 22, thereby improving the accuracy of the measurement. The signal transmitting area 26 is set as a circular area, and the signal receiving area 27 is set as a circular area. The diameter of the circular area containing the signal transmitting area 26 is the same as the diameter of the circular area containing the signal receiving area 27.

[0042] The distance between the signal transmitter 21 and the two rollers is the same as the distance between the signal receiver 22 and the two rollers, which facilitates the conversion of signal change data and size data.

[0043] In some embodiments, such as Figure 4 As shown, the interval between the two cut pieces 10 includes a first interval and a second interval, as follows: Figure 3 As shown, the first interval is set to L1, and the second interval is set to L2. The first interval extends along a first direction, and the second interval extends along a second direction. The first and second directions intersect. The first direction is defined as the height direction of the cutting adaptive adjustment system 100, as shown below. Figure 1 The Z direction is shown, and the second direction is set as the length direction of the cutting adaptive adjustment system 100, such as... Figure 1 The x-direction is shown.

[0044] The length of the first interval L1 and the length of the second interval L2 can be measured simultaneously by the detection mechanism 2, and the first interval L1 and the second interval L2 can be adjusted to a suitable interval by the adjustment mechanism 3.

[0045] In some embodiments, the first interval ranges from 0µm to 50µm, and the second interval ranges from 5µm to 50µm. By setting the first interval range to 0µm to 50µm and the second interval range to 5µm to 50µm, the cutting adaptive adjustment system 100 is adapted to cut electrodes and diaphragms of different types, and improves the cutting edge quality of the cut electrodes.

[0046] In a specific embodiment, the distance between the first cut piece 101 and the second cut piece 102 corresponding to the first interval range can be -50um, -40um, -30um, -20um, -10um, 0um, 10um, 20um, 30um, 40um, 50um, or any value between any two of the above, or a range between any two of the above values. The distance between the first cut piece 101 and the second cut piece 102 corresponding to the second interval range can be 5um, 10um, 15um, 20um, 25um, 30um, 35um, 40um, 45um, 50um, or any value between any two of the above, or a range between any two of the above values.

[0047] In some embodiments, such as Figure 3 As shown, the adjustment mechanism 3 includes an adjustment bolt 31, which is movably connected to the mounting bracket 13. The adjustment bolt 31 can adjust the interval between the first cutting piece 101 and the second cutting piece 102.

[0048] like Figure 2 and Figure 3 As shown, the mounting bracket 13 includes a support plate 131, a left bracket 132, and a right bracket 133. The left bracket 132 is connected to the left side of the support plate 131, and the right bracket 133 is connected to the right side of the support plate 131. Both the left bracket 132 and the right bracket 133 include an upper bracket 134 and a lower bracket 135. One end of the first guide roller 11 is connected to the upper bracket 134 of the left bracket 132, and the other end of the first guide roller 11 is connected to the upper bracket 134 of the right bracket 133. One end of the second guide roller 12 is connected to the lower bracket 135 of the left bracket 132, and the other end of the second guide roller 12 is connected to the lower bracket 135 of the right bracket 133.

[0049] The upper bracket 134 and lower bracket 135 of the left bracket 132 and the right bracket 133 are connected by two adjusting bolts. The first interval between the first cutting piece 101 and the second cutting piece 102 can be adjusted by adjusting the connection position of the adjusting bolts.

[0050] like Figure 2As shown, the adjustment mechanism 3 also includes an adjustment knob 32, which is movably connected to the mounting bracket 13 and either the first guide roller 11 or the second guide roller 12. The adjustment knob includes a first guide roller adjustment knob and a second guide roller adjustment knob. The first guide roller adjustment knob is movably connected to the first guide roller 11 and the mounting bracket 13, and is configured to adjust the mounting position of the first guide roller 11 relative to the mounting bracket 13 along a second direction. The second guide roller adjustment knob is movably connected to the second guide roller 12 and the mounting bracket 13, and is configured to adjust the mounting position of the second guide roller 12 relative to the mounting bracket 13 along a second direction, thereby adjusting the second interval between the first cutting piece 101 and the second cutting piece 102.

[0051] In some embodiments, reference Figure 2 As shown, the first cutting element 101 protrudes from the first roller 11, and the second cutting element 102 is flush with the second roller 12. The second roller 12 is provided with a relief groove 121, which is configured to avoid the first cutting element 101, so that when the electrode sheet to be cut is sandwiched between the first roller 11 and the second roller 12, the electrode sheet can be cut at the first cutting element 101 and the second cutting element 102 to form an electrode sheet with a suitable width.

[0052] Embodiments of this application also provide an electrode thermal bonding apparatus, which includes a cutting adaptive adjustment system 100 and an electrode thermal bonding device. The cutting adaptive adjustment system is configured to cut electrode sheets or diaphragms, and the electrode thermal bonding device is configured to form a thermally bonded electrode assembly by hot rolling of the cut electrode sheets and diaphragms.
