[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0027] See Figure 1As shown, the solid electrode composite transfer and slitting integrated equipment of this invention includes an unwinding unit, a composite transfer unit, a peeling unit, a slitting unit, and a rewinding unit. There are three unwinding units, which respectively unwind the upper electrolyte carrier, the electrode layer, and the lower electrolyte carrier. The composite transfer unit is used to perform composite transfer on the unwound upper electrolyte carrier, the electrode layer, and the lower electrolyte carrier. The peeling unit is used to peel off the electrolyte carrier base film on the composite electrode formed after composite transfer. The slitting unit is used to slit the composite electrode after the electrolyte base film is peeled off into multiple pieces. The rewinding unit is used to rewind each of the multiple slit composite electrodes.
[0028] In some embodiments, the unwinding unit includes three unwinding shafts: an upper electrolyte membrane unwinding shaft 1, an electrode layer unwinding shaft 2, and a lower electrolyte membrane unwinding shaft 3, such as... Figure 1 As shown, each unwinding unit is equipped with a color mark sensor 4, an unwinding correction sensor 5, an unwinding end tape receiving platform 6, an unwinding end tension shaft 7, an incoming material ultrasonic dust removal device 8, and an unwinding magnetic rod 9 arranged from front to back along the unwinding path. The unwinding correction sensor 5 is equipped with one on each of the upper and lower electrolyte membranes and the electrode layer to realize the correction function of the electrode sheet tape when the electrode roll is unwound. The unwinding end tape receiving platform is equipped with one on each of the upper and lower electrolyte membranes and the electrode layer. The unwinding end tension shaft is equipped with one on each of the upper and lower electrolyte membranes and the electrode layer.
[0029] For example, the unwinding unit of the electrode layer has two color mark sensors 4, which are arranged on the upper and lower sides of the electrode layer, that is, one is equipped on each of the A and B sides of the electrode layer. The unwinding unit of the upper electrolyte membrane and the unwinding unit of the lower electrolyte membrane each have one color mark sensor 4, which are arranged on the upper side of the corresponding electrolyte membrane to realize the detection of the adhesive tape and uncoated areas of the incoming electrode roll.
[0030] For example, the unwinding unit of the electrode layer has two ultrasonic dust removal devices 8 and two unwinding magnetic rods 9, which are staggered along the conveying path and arranged vertically above and below the electrode layer. In this application, one ultrasonic dust removal device 8 is provided on each side of the upper and lower electrolyte membrane material areas, and one is provided on each of the A and B sides of the electrode layer, to achieve surface cleaning of the incoming electrode sheet; one unwinding magnetic rod is provided on each side of the upper and lower electrolyte membrane material areas, and one is provided on each of the A and B sides of the electrode layer, to achieve removal of magnetic materials from the surface of the incoming electrode sheet.
[0031] In this embodiment, the upper electrolyte membrane unwinding shaft 1 unwinds counterclockwise to ensure that the material area side faces downward; the electrode layer unwinding shaft 2 can unwind clockwise or counterclockwise to allow the A and B sides of the electrode layer to be interchanged; and the lower electrolyte membrane unwinding shaft 3 unwinds clockwise to ensure that the material area side faces upward.
[0032] For example, in this embodiment of the application, the composite transfer unit includes a preheating roller 10 and a pressure main roller 12. The preheating roller 10 preheats the electrode layer before composite transfer, and the pressure main roller 12 has a heating function to achieve composite transfer of the electrolyte membrane and the electrode layer. The pressure main roller 12 consists of an upper roller and a lower roller. The electrolyte membrane and the electrode layer pass between the upper and lower rollers, and are heated and squeezed by the pressure main roller to achieve composite transfer. Specifically, the heating function of the preheating roller and the pressure main roller can be selected for activation or temperature setting according to the state of the composite electrode sheet.
[0033] In this application, a preheating roller is provided on each of the electrode layers A and B to preheat the electrode layers before composite transfer. Furthermore, a process correction sensor 11 is arranged before the pressure main roller 12, with one sensor on each of the upper and lower electrolyte membranes and the electrode layer, to correct the electrode sheet movement before it enters the pressure main roller, ensuring the alignment between the electrolyte membrane and the electrode layer after composite transfer.
[0034] In this embodiment, the peeling unit includes: a peeling roller 13, which peels off the upper and lower electrolyte carrier base films after composite transfer, and outputs the composite electrode sheet, the upper electrolyte carrier base film, and the lower electrolyte carrier base film; a peeling and splicing platform 14, preferably three, one of which is set before the upper and lower electrolyte carrier base films are wound up; a composite electrode sheet drive roller 15, which provides power for the composite electrode sheet after the electrolyte carrier base film has been peeled off; and two electrolyte carrier base film winding shafts 16, one at the top and one at the bottom, for winding up the upper and lower electrolyte carrier base films respectively.
[0035] In some embodiments, the slitting unit includes a slitting blade assembly 17, which consists of upper and lower slitting blades and a blade holder, and is used to slit the composite electrode sheet into multiple pieces along the length direction or the conveying direction. In this application, it is preferably slitting into four pieces, and after slitting, multiple composite electrode sheets are formed into multiple pieces, which are respectively wound up by multiple winding shafts.
[0036] The cutting positions of the composite electrode sheet are the blank position in the middle of the composite electrode sheet and the middle position of each material area. For example, a composite electrode sheet is divided into four pieces with the same width and structure. Each composite electrode sheet has a single-sided tab, realizing the "one out of four" function.
[0037] See Figure 2As shown, the composite electrode sheet after transfer is cut into four electrode sheets. Before cutting, the composite electrode sheet consists of two side edge current collectors 31 and 35 and a middle current collector 33, which are separated into two composite electrode sheet material areas, namely the first composite electrode sheet material area 32 and the second composite electrode sheet material area 34. When the composite electrode sheet passes between the upper blade holder 171 and the lower blade holder 172, it is cut by three cutting blades to form four composite electrode sheets with the same structure after cutting, each with a single side edge current collector. The two side cutting blades 8 and 10 cut the composite electrode sheet material areas, and the middle cutting blade 9 cuts the middle current collector. Finally, the "one-to-four" composite electrode sheet after transfer is achieved, which improves the process efficiency.
[0038] In this application, an integrated device is used to perform composite transfer of electrolyte membrane and electrode layer with blank space in the middle, and to cut the blank space and material area of the composite electrode sheet. This device can achieve "one-to-four" composite electrode sheet production, thus improving the efficiency of composite electrode sheet production.
[0039] Specifically, if the incoming electrode sheet is a single-strip coated sheet, it can be configured with a set of slitting blades, with the cutting position in the middle of the material area, to achieve the "one-to-two" function, that is, to divide one composite electrode sheet into two electrode sheets with identical width dimensions and structure, each composite electrode sheet having a single-sided tab. Alternatively, according to the actual assembly requirements, asymmetrical cutting can be achieved when cutting the material area by adjusting the position of the slitting blades.
[0040] In some embodiments, the slitting blade has a diameter of 13cm, and the upper slitting blade angle can be machined to 15°. ~ 30°, with a lower slitting blade angle of 90°. Up to three sets of blades can be installed on the blade holder. According to the required width of the composite electrode sheet, a corresponding isolation ring is customized and installed between the slitting blades to cut the composite transfer electrode sheet into four pieces, providing a suitable electrode sheet form and size for assembly.
[0041] In some embodiments, the slitting unit further includes a slitting tension shaft 18, which provides appropriate tension to the composite electrode sheet before it enters the slitting blade after transfer, ensuring the flatness of the composite electrode sheet.
[0042] In some embodiments, a laser thickness measuring component 19 is also included to detect the thickness of the composite electrode after composite transfer and peeling off the electrolyte carrier base film; the laser thickness measuring component 19 is arranged between the composite electrode drive roller 15 and the slitting unit.
[0043] In some embodiments, an ultrasonic dust removal device 20 is also included after slitting, which is used to clean the surface of each composite electrode sheet after slitting. One device is provided on each of the A and B sides of each slitting composite electrode sheet, for a total of eight, so as to achieve cleaning of the A and B surfaces of the slitting composite electrode sheets.
[0044] In some embodiments, the slit magnetic rods 21 are also included for removing the magnetic material from the surface of each composite electrode sheet after slitting. One magnetic rod is provided on each of the A and B sides of each composite electrode sheet, for a total of eight, to remove the magnetic material from the A and B sides of the slit composite electrode sheets.
[0045] In some embodiments, a visual inspection component 22 is also included to detect the size and surface defects of the slit composite electrode sheets. One component is set on each of the A and B sides of each slit composite electrode sheet, for a total of eight components.
[0046] After the composite electrode sheets are slit, each slit electrode sheet is subjected to online size and defect detection, as well as demagnetization and dust removal, to achieve refined inspection of each composite electrode sheet after slit.
[0047] In some embodiments, there are multiple winding units, such as four in this application, which respectively wind up the four composite electrode sheets formed after slitting. The winding units include four composite electrode sheet winding shafts 25, one for each composite electrode sheet after slitting, and the specific number is set according to the number of composite electrode sheets slit out.
[0048] In some embodiments, the winding unit includes a winding correction sensor 23, one for each composite electrode sheet after slitting, for a total of four, to realize the alignment function or winding correction function during winding.
[0049] In some embodiments, the winding unit includes a winding and splicing platform 24, one for each composite electrode sheet after slitting, for a total of four. The winding and splicing platform 24 is arranged upstream of the composite electrode sheet winding shaft 25 and downstream of the winding correction sensor 23.
[0050] In this embodiment of the application, the solid electrode composite transfer and slitting integrated equipment also includes multiple conveyor rollers ( Figure 1 The circles not shown in the attached diagram are the conveyor rollers. They are spaced apart and arranged in a wave-like pattern along the conveying path to transfer the film material and electrode layer material.
[0051] In this embodiment, the solid electrode composite transfer and slitting integrated equipment is operated as follows:
[0052] Step S101: Unwinding the electrolyte membrane electrode roll and the electrode layer electrode roll.
[0053] By rotating the unwinding shafts of the upper and lower electrolyte membrane electrode rolls and electrode layers, the electrode rolls are released in the form of single-layer electrode sheets. The electrode sheets are then processed through color mark sensors, web correction sensors, dust removal and demagnetization, etc., to achieve incoming material detection, unwinding correction, and dust removal and demagnetization of the electrode sheet surface, so that the electrode sheets reach the optimal state before composite transfer.
[0054] Step S102: Composite transfer printing, realizing the three-in-one composite electrode.
[0055] The electrode layer is preheated on both sides A and B by a preheating roller. To ensure the edge alignment of the composite transfer, the electrolyte membrane and electrode layer are corrected before entering the pressure main roller. Then, they enter the pressure main roller in a pre-set alignment manner. Under the action of pressure and temperature, the electrolyte membrane and electrode layer are composited to obtain a three-in-one composite electrode sheet.
[0056] Step S103: Electrolyte carrier base film peeling and composite electrode driving.
[0057] After the composite transfer, the composite electrode sheet is peeled off from the upper and lower electrolyte carrier base films by the peeling roller. The waste electrolyte carrier base film is then wound up by the electrolyte carrier base film winding shaft. The composite electrode sheet is then powered by the composite electrode sheet drive roller and moved to the next processing unit.
[0058] Step S104: Composite electrode thickness detection.
[0059] The thickness of the composite electrode sheet after composite transfer is measured using a laser thickness gauge.
[0060] Step S105: Slice the composite electrode to achieve one-to-many output, such as one-to-four output.
[0061] The composite electrode sheet, after the upper and lower electrolyte carrier base films have been peeled off, is cut and separated by the meshing action of the upper and lower cutters of the three-part cutting unit.
[0062] Step S106: Dust removal and demagnetization of composite electrode sheets.
[0063] Ultrasonic dust removal is used to clean the surface of each slit composite electrode sheet. After slit, a magnetic rod is used to demagnetize the surface of each slit composite electrode sheet. A visual inspection mechanism is used to detect the size and surface defects of the slit composite electrode sheets.
[0064] Step S106: Rewind the composite electrode.
[0065] The slit composite electrodes are then fed to the composite electrode take-up shaft via a correction sensor.
[0066] See Figures 3-6 The diagram illustrates the structural changes of materials during the composite conversion process of incoming material processing using the equipment of this embodiment of the application. Figures 3-6 In the diagram, 411 is the upper electrolyte carrier base film, 422 is the upper electrolyte, 43 is the upper electrode layer material area, 44 is the current collector, 45 is the lower electrode layer material area, 46 is the lower electrolyte, and 47 is the lower electrolyte carrier base film.

Figure 4 It shows the result of Figure 3 The structure of the three-in-one composite electrode formed after the material transfer is shown.
