[0002] Compared to liquid batteries, solid-state batteries use solid electrolytes instead of liquid electrolytes and separators, resulting in higher energy density and the ability to store more energy in the same volume. Currently, existing solid-state battery manufacturing processes are not yet mature. During isostatic pressing, the solid electrolyte membrane and electrode membranes are prone to misalignment. Additionally, the edges of the anode and cathode films are susceptible to bending contact, leading to short circuits. Therefore, a bonding frame is needed to coat the electrodes to improve adhesion and prevent misalignment and bending contact issues.

[0003] In the production process of the electrode, the film strip is conveyed by the conveying mechanism to the film frame forming station. Then, the film strip is cut by the cutting mechanism to form a film frame. Subsequently, the electrode and the film frame are laminated together by the laminating mechanism. Finally, the glue frame is manufactured on the electrode by the glue frame forming device.

[0030] The following describes, with reference to the accompanying drawings, a membrane frame forming and transfer laminating method and apparatus, a frame printing machine, and a solid-state battery production line according to embodiments of the present invention.

[0031] This invention aims to provide an embodiment of a solid-state battery production line. Specifically, this invention aims to provide an embodiment of a frame printing machine for a solid-state battery production line.

[0032] Furthermore, considering the widespread applicability of the technical problem solved by this application, the present invention also aims to provide an embodiment of a membrane frame forming and transfer laminating device.

[0033] In the electrode production process, the film strip is conveyed by the conveying mechanism 100 to the film frame forming station. Then, the film strip is cut by the cutting mechanism to form a film frame. Subsequently, the electrode and the film frame are laminated together by the laminating mechanism 200. Finally, a film frame is formed on the electrode by the film frame forming device. However, existing solid-state battery production equipment requires manual intervention during film frame transfer and waste removal, leading to unstable production cycles, potential deformation or damage to the film frame, and impacting overall production efficiency.

[0034] Reference Figures 1 to 6 To address the above issues, in this embodiment, the membrane frame forming and transfer laminating device includes a conveying mechanism 100, a cutting mechanism, a laminating mechanism 200, and a transfer mechanism 300.

[0035] Reference Figures 1 to 3 The conveying mechanism 100 is used to convey the membrane material strip. In this embodiment, the membrane material strip is a PI film. The thickness of the membrane material strip can be 10 μm. It is understood that polyimide (PI) film has excellent high temperature resistance, corrosion resistance, hydrolysis resistance, and electrical insulation properties, and can be made ultra-thin, thus reducing the thickness of the battery cell structure containing PI film. Of course, it is not excluded that other membrane materials with excellent electrical insulation properties can be used for the membrane material strip.

[0036] A membrane frame forming station is provided in the conveying direction of the membrane strip. The membrane frame forming station is configured to cut the membrane strip by a cutting mechanism so that the membrane strip is formed into a membrane frame.

[0037] Reference Figure 3 In this embodiment, the conveying mechanism 100 includes an unwinding assembly 110, a first winding assembly 120, and a second winding assembly 130. The unwinding assembly 110 is used to unwind the film strip. The first winding assembly 120 is used to wind up the cut waste strip. The second winding assembly 130 is used to peel off and wind up the release film on the film strip. The unwinding assembly 110 is a conventional unwinding machine, and the first and second winding assemblies 120 and 130 are conventional winding machines. Those skilled in the art should understand their specific structure and working principle, which will not be described in detail here. Under the coordinated operation of the unwinding assembly 110, the first winding assembly 120, and the second winding assembly 130, the film strip can be continuously released and conveyed to the film frame forming station. Simultaneously, the release film on the film strip is peeled off, and the waste strip can be wound up. Furthermore, several rollers can be arranged between the unwinding assembly 110 and the first winding assembly 120 to adjust the tension and extension direction of the film strip.

[0038] The cutting mechanism is configured to cut the membrane strip, forming a membrane frame on the strip. Specifically, the cutting mechanism is a laser die-cutting mechanism or a knife die-cutting mechanism. In some examples, a laser die-cutting mechanism is used, which can cut the membrane frame from the membrane strip using laser die-cutting. In other examples, a knife die-cutting mechanism is used, which can cut the membrane frame from the membrane strip in one pass.

[0039] Reference Figures 1 to 4The lamination mechanism 200 is configured to laminate the electrode and the membrane frame together. In this embodiment, the surface of the membrane frame is provided with an adhesive layer, so only the membrane frame and the electrode need to be bonded together, without the need for heat pressing. Therefore, the lamination mechanism 200 includes a picking robot, which picks up the electrode from the storage area and transports it to the first plate 310, so that the electrode and the membrane frame are bonded together, making the lamination work simpler. Of course, in other embodiments, the surface of the membrane frame is not provided with an adhesive layer, in which case the membrane frame is laminated to the electrode by a heat pressing process.

[0040] Reference Figures 1 to 6 The transfer mechanism 300 is located below the membrane material strip. The transfer mechanism 300 includes a first plate 310 and a second plate 320. The first plate 310 is configured to enter the membrane frame forming station and adsorb the membrane material strip, or to adsorb and drive the membrane frame away from the membrane frame forming station. The second plate 320 is configured to embed into the first plate 310 to cooperate with the first plate 310 in adsorbing the membrane material strip, or to adsorb and drive the waste material in the middle of the membrane frame away from the first plate 310. Specifically, the first plate 310 has a through hole, the second plate is embedded in the through hole, and the upper surfaces of the first plate 310 and the second plate 320 are flush.

[0041] During operation, the first plate 310 enters the membrane frame forming station and approaches the membrane material strip; the second plate 320 is embedded in the first plate 310; the second plate 320 and the first plate 310 work together to adsorb the membrane material strip; then the membrane material strip is cut by the cutting mechanism to form a membrane frame; finally, the second plate 320 drives the waste material in the middle of the membrane frame to leave the first plate 310 to achieve waste discharge; the first plate 310 drives the membrane frame to leave the membrane frame forming station and transfer it to the laminating mechanism 200 to achieve membrane frame transfer and lamination.

[0042] Reference Figure 5 A first cutting groove 311 is formed between the first plate 310 and the second plate 320. A second cutting groove 312 is provided on the first plate 310 outside the first cutting groove 311. A receiving space adapted to the membrane frame is formed between the first cutting groove 311 and the second cutting groove 312. The first cutting groove 311 and the second cutting groove 312 form a clearance space for cutting, thereby improving the cutting quality and ensuring the quality of the membrane frame. After cutting, the membrane frame is located in the receiving space, and the waste material in the middle of the membrane frame corresponds exactly to the second plate 320, thereby facilitating the discharge of the waste material in the middle of the membrane frame through the second plate 320.

[0043] Reference Figure 5 and Figure 6In this embodiment, the first plate 310 and the second plate 320 are respectively provided with a first adsorption hole 33 and a second adsorption hole 321. Two sets of first adsorption holes 33 are provided, one inside the receiving space and the other outside. This allows for the simultaneous and stable adsorption of the film strip through both sets of first adsorption holes 33, improving cutting quality. It also facilitates the release of the film strip through the first adsorption holes 33 outside the receiving space and the fixation of the film frame through the first adsorption holes 33 inside the receiving space after cutting, thus facilitating subsequent transfer of the film frame.

[0044] It is understood that the first adsorption hole 33 and the second adsorption hole 321 can be round holes, elongated holes, etc., and the first adsorption hole 33 and the second adsorption hole 321 are arranged in an array. The first adsorption hole 33 and the second adsorption hole 321 are respectively connected to the vacuum circuit, and the vacuum circuit is connected to the vacuum pumping equipment through a pipe. The first plate 310 enters the membrane frame forming station and approaches the membrane material belt, and the second plate 320 is embedded in the first plate 310. At this time, the first plate 310 and the second plate 320 are located below the membrane material belt. The vacuuming equipment starts vacuuming, and the first adsorption hole 33 and the second adsorption hole 321 work together to adsorb the membrane material strip, so that the membrane material strip is stably fixed on the first plate 310 and the second plate 320. At this time, the membrane material strip is cut by the cutting mechanism, which can improve the quality of the membrane frame. After the cutting is completed, the second plate 320 adsorbs the waste material in the middle of the membrane frame, so that the second plate 320 carries the waste material away from the first plate 310 to realize the discharge of waste material. Meanwhile, the first adsorption hole 33 located outside the receiving space in the first plate 310 releases the adsorption of the membrane material strip, and the first adsorption hole 33 located in the middle of the receiving space adsorbs the membrane frame, thus realizing the fixation of the membrane frame. Then, the first plate 310 carries the membrane frame away from the membrane frame forming station, thereby realizing the transfer of the membrane frame.

[0045] It should be noted that the size, shape, and arrangement of the adsorption pores can be set according to actual needs, and no specific limitations are made here.

[0046] Reference Figures 1 to 6 Furthermore, the transfer mechanism 300 also includes a first driving component and a second driving component. The first driving component is connected to the first plate 310. The first driving component can drive the first plate 310 into the membrane frame forming station and close to the membrane material strip, or can drive the membrane frame away from the membrane frame forming station. The second driving component is connected to the second plate 320. The second driving component can drive the second plate 320 to embed into the first plate 310 to cooperate with the first plate 310 to adsorb the membrane material strip, or can drive the waste material in the middle of the membrane frame away from the first plate 310.

The first vertical moving unit 340 is disposed in the first horizontal moving unit 330, and the first plate 310 is disposed in the first vertical moving unit 340. The first horizontal moving unit 330 can drive the first plate 310 into or out of the film frame forming station, and the first vertical moving unit 340 can drive the first plate 310 to approach or move away from the film strip. The second driving assembly includes a second horizontal moving unit 350 and a second vertical moving unit 360. The second vertical moving unit 360 is disposed in the second horizontal moving unit 350, and the second plate 320 is disposed in the second vertical moving unit 360. The second horizontal moving unit 350 can drive the second plate 320 into or away from the film frame forming station, and the second vertical moving unit 360 can drive the second plate 320 to embed into or move away from the first plate 310.

[0048] The first horizontal movement unit 330, the first vertical movement unit 340, the second horizontal movement unit 350, and the second vertical movement unit 360 are all configured with electric push rods, gear and rack structures, or screw and nut structures, etc. Furthermore, the movement direction of the first horizontal movement unit 330 is horizontal and perpendicular to the conveying direction of the film strip, while the movement direction of the second horizontal movement unit 350 is consistent with the conveying direction of the film strip.

[0049] During operation, the first transverse unit 330 drives the first plate 310 into the film frame forming station, positioning the first plate 310 below the film strip; subsequently, the first vertical unit 340 drives the first plate 310 upward, bringing it closer to the film strip; the second transverse unit 350 drives the second plate 320 to move, positioning it below the first plate 310; the second vertical unit 360 drives the second plate 320 upward, embedding it into the first plate 310; then, the second plate 320 and the first plate 310 work together to adsorb the film strip; after cutting is completed... The second vertical moving unit 360 drives the second plate 320 to descend, causing the second plate 320 to carry the waste material in the middle of the film frame away from the first plate 310. Finally, the second horizontal moving unit 350 drives the second plate 320 to move, causing the second plate 320 to carry the waste material away from the film frame forming station, thereby realizing the discharge of waste material. The first vertical moving unit 340 drives the first plate 310 to descend, causing the first plate 310 to carry the film frame away from the film material strip. Finally, the first horizontal moving unit 330 drives the first plate 310 to move, causing the first plate 310 to carry the film frame away from the film frame forming station, thereby waiting for the subsequent lamination work.

[0050] Reference Figures 1 to 3In some embodiments of this application, the membrane frame forming and transfer laminating device further includes a clamping mechanism 400. Specifically, the clamping mechanism 400 includes a first clamping member 410 and a second clamping member 420, which are respectively disposed at the front and rear ends of the membrane frame forming station. The first clamping member 410 and the second clamping member 420 are used to clamp the membrane strip. Specifically, when cutting is required, the first clamping member 410 and the second clamping member 420 cooperate to clamp the front and rear ends of the membrane strip, thereby improving the stability of cutting and ensuring the quality of the membrane frame.

[0051] Furthermore, the clamping mechanism 400 also includes a translation component 430, the movement direction of which is consistent with the conveying direction of the film strip, and the first clamping member 410 is disposed on the translation component 430. The translation component 430 can be configured as an electric push rod, a gear and rack structure, or a screw and nut structure, etc. By driving the first clamping member 410 to move through the translation component 430, the first clamping member 410 can assist in conveying the film strip. Simultaneously, during cutting, the translation component 430 can drive the first clamping member 410 to pull back the film strip, taut the film strip, thereby improving the stability and reliability of the cutting process. It is conceivable that the second plate 320 is provided with a connecting frame 322, which has a clearance opening 323 for avoiding the first clamping member 410, allowing the first clamping member 410 to reciprocate along the clearance opening 323, improving the stability and smoothness of operation.

Specifically, the detection mechanism 500 includes a detection component 510, a flipping component 520, a first receiving platform 530, and a second receiving platform 540. The flipping component 520 is disposed on one side of the detection component 510, and the first receiving platform 530 and the second receiving platform 540 are vertically disposed on one side of the detection direction of the detection component 510. The first receiving platform 530 and the second receiving platform 540 are respectively connected to the flipping component 520, and the flipping component 520 drives the first receiving platform 530 and the second receiving platform 540 to exchange positions. The flipping component 520 is configured as a rotary cylinder, which has a simple structure and stable operation. Both the first receiving platform 530 and the second receiving platform 540 use adsorption to fix the electrode sheet, which has a simple structure, is easy to operate, and improves the quality of the electrode sheet.

[0053] After the electrode and membrane frame are laminated, the electrode is conveyed to the first receiving platform 530 for fixation. Then, the flipping assembly 520 drives the first receiving platform 530 and the second receiving platform 540 to switch positions. At this time, the first receiving platform 530 corresponds to the detection assembly 510 to realize the detection of the electrode, while the second receiving platform 540 is used for electrode unloading and loading for the next round of electrode detection. By adopting the above structure, electrode detection and electrode unloading can be realized simultaneously, shortening the electrode detection time and improving work efficiency.

[0054] It should be noted that the electrode inspection is carried out by a robotic arm, which is existing technology and is not restricted in this application.

[0055] In the membrane frame forming and transfer laminating apparatus described in this application embodiment, during operation, the conveying mechanism 100 conveys the membrane material strip to the membrane frame forming station; the first transverse unit 330 drives the first plate 310 into the membrane frame forming station, and the first vertical unit 340 drives the first plate 310 closer to the membrane material strip; the second transverse unit 350 drives the second plate 320 into the membrane frame forming station, so that the second plate is located below the first plate 310, and the second vertical unit 360 drives the second plate 320 to embed into the first plate 310; the first plate 310 and the second plate 320 cooperate to adsorb the membrane material strip; then the cutting mechanism cuts the membrane material strip to form a membrane frame; the second plate 320... Waste material in the middle of the membrane frame is adsorbed, and the second plate 320 is driven away from the first plate 310 by the second vertical moving unit 360, and the second plate 320 is driven away from the membrane frame forming station by the second horizontal moving unit 350, thereby realizing the discharge of waste material; the first plate 310 adsorbs the membrane frame, and the first plate 310 is driven away from the membrane material strip by the first vertical moving unit 340, and the first plate 310 drives the membrane frame away from the membrane frame forming station by the first horizontal moving unit 330, thereby realizing the transfer of the membrane frame; the electrode and the membrane frame are laminated together by the laminating mechanism 200; the laminated electrode is transported to the receiving platform, and the receiving platform is repositioned by the flipping assembly 520 to realize the detection of the electrode.

[0056] By working together with the first plate 310 and the second plate 320, the membrane frame can be formed, transferred and laminated. At the same time, the waste material can be automatically discharged, ensuring the integrity and stability of the membrane frame during the transfer process. Compared with the traditional transfer method that requires manual intervention, it can significantly improve the stability of the production cycle, reduce the risk of membrane frame deformation or damage caused by improper manual operation, improve overall production efficiency and ensure product quality.

[0057] Reference Figures 7 to 8 This application also provides a membrane frame forming and transfer laminating method, which is applied to the above-mentioned membrane frame forming and transfer laminating apparatus.

[0058] Reference Figure 7 The membrane frame forming and transfer lamination method includes, but is not limited to, the following steps: Step S110: The membrane material belt is conveyed, and a membrane frame forming station is set in the conveying direction of the membrane material belt; Step S120: Drive the first plate 310 and the second plate 320 to move, so that the first plate 310 and the second plate 320 enter the membrane frame forming station, and the second plate 320 is embedded in the first plate 310. Step S130: The first plate 310 and the second plate 320 are fitted together with the adsorption membrane material strip; Step S140: Cut the membrane strip to form a membrane frame on the membrane strip; Step S150: Drive the second plate 320 and the first plate 310 to move, so that the second plate 320 carries the waste material in the middle of the membrane frame away from the first plate 310 and away from the membrane frame forming station, and the first plate 310 carries the membrane frame away from the membrane material strip and away from the membrane frame forming station. Step S160: The electrode is conveyed onto the first plate 310 so that the electrode is laminated with the membrane frame.

[0059] During operation, the conveying mechanism 100 transports the membrane material strip to the membrane frame forming station; drives the first plate 310 into the membrane frame forming station and closes it to the membrane material strip; drives the second plate 320 into the membrane frame forming station and embeds it into the first plate 310; the membrane material strip is adsorbed by the cooperation of the second plate 320 and the first plate 310; then the membrane material strip is cut to form a membrane frame; the second plate 320 is driven to adsorb and carry the waste material in the middle of the membrane frame away from the membrane frame forming station to achieve waste discharge; the first plate 310 is driven to adsorb and carry the membrane frame away from the membrane frame forming station to achieve membrane frame transfer; finally, the electrode is transported onto the first plate 310 so that the electrode and the membrane frame are laminated.

[0060] The membrane frame forming, transfer and lamination method described in this application embodiment can realize the forming, transfer and lamination of the membrane frame, and can also realize the automatic discharge of waste materials, ensuring the integrity and stability of the membrane frame during the transfer process. Compared with the traditional transfer method that requires manual intervention, it can significantly improve the stability of the production cycle, reduce the risk of membrane frame deformation or damage caused by improper manual operation, improve the overall production efficiency, and ensure product quality.

[0061] Reference Figure 8 , Figure 8 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S110, which includes, but is not limited to, the following steps: Step S210: Unwind the film strip; Step S220: Peel and wind up the release film on the film strip; wherein, the surface of the film strip is provided with an adhesive layer; Step S230: Rewind the cut waste strip.

[0062] The membrane strip is conveyed by simultaneous unwinding and rewinding, and then transported to the membrane frame forming station, facilitating continuous and rapid cutting of the required membrane frames. Furthermore, during the cutting process, waste strips can be rewound for the next cutting operation, eliminating the need for waste strip cleanup and effectively preventing the reduction in lamination and cutting efficiency due to waste removal.

[0063] Because the surface of the membrane strip has an adhesive layer, it is easy for the cut membrane frame and the electrode to be laminated through the adhesive layer. Therefore, during the unwinding process of the membrane strip, it is necessary to peel off the release film on the membrane strip and rewind it. There is no need to peel off the release film from the cut membrane frame.

[0064] Reference Figure 9 , Figure 9 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S120, which includes, but is not limited to, the following steps: Step S310: Drive the first plate 310 to slide, so that the first plate 310 enters the membrane frame forming station; Step S320: Drive the first plate 310 to rise, so that the first plate 310 is close to the film strip; Step S330: Drive the second plate 320 to slide, so that the second plate 320 enters the membrane frame forming station and is located below the first plate 310; Step S340: Drive the second plate 320 to rise, so that the second plate 320 is embedded in the first plate 310.

[0065] Specifically, the first plate 310 is connected to a first driving assembly, which includes a first horizontal movement unit 330 and a first vertical movement unit 340. The first vertical movement unit 340 is disposed within the first horizontal movement unit 330, and the first plate 310 is disposed within the first vertical movement unit 340. Correspondingly, the second plate 320 is connected to a second driving assembly, which includes a second horizontal movement unit 350 and a second vertical movement unit 360. The second vertical movement unit 360 is disposed within the second horizontal movement unit 350, and the second plate 320 is disposed within the second vertical movement unit 360. The first horizontal movement unit 330 drives the first plate 310 to slide, so that the first plate 310 enters the membrane frame forming station; then the first vertical movement unit 340 drives the first plate 310 to rise, so that the first plate 310 approaches the membrane material strip; then the second horizontal movement unit 350 drives the second plate 320 to slide, so that the second plate 320 enters the membrane frame forming station, at which time the second plate 320 is located below the first plate 310; the second vertical movement unit 360 drives the second plate 320 to rise, so that the second plate 320 is embedded in the first plate 310, thereby facilitating the first plate 310 and the second plate 320 to cooperate in adsorbing the membrane material strip, thereby improving the subsequent cutting quality of the membrane material strip and improving the quality of the membrane frame.

[0066] In this embodiment, the first horizontal movement unit 330, the first vertical movement unit 340, the second horizontal movement unit 350, and the second vertical movement unit 360 are all configured as electric push rods, gear and rack structures, or screw and nut structures, etc.

[0067] In step S130, the first plate 310 and the second plate 320 are respectively provided with a first adsorption hole 33 and a second adsorption hole 321. Among them, there are two sets of first adsorption holes 33. The two sets of first adsorption holes 33 can not only cooperate to adsorb the film strip to improve the cutting quality, but also release the film strip after the cutting is completed and adsorb the film frame, so as to facilitate the subsequent transfer and lamination of the film frame by the first plate 310.

[0068] Reference Figure 10 , Figure 10 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S140, which includes, but is not limited to, the following steps: Step S410: Clamp the film strips at both ends of the membrane frame forming station; Step S420: Cut the membrane strip to form a membrane frame on the membrane strip.

[0069] In step S410, a clamping mechanism 400 is used to clamp the film strips at both ends of the film frame forming station. Specifically, the clamping mechanism 400 includes a first clamping member 410 and a second clamping member 420, which are respectively disposed at the front and rear ends of the film frame forming station. The first clamping member 410 and the second clamping member 420 are used to clamp the film strips.

[0070] By clamping the front and rear ends of the film strip with the first clamping member 410 and the second clamping member 420 respectively, the cutting stability can be improved and the quality of the film frame can be guaranteed. Furthermore, the first clamping member 410 is connected to a translation component 430, which drives the first clamping member 410 to move, thereby enabling the first clamping member 410 to assist in the conveying of the film strip. Simultaneously, during cutting, the translation component 430 can drive the first clamping member 410 to pull back the film strip, taut the film strip, thus improving the stability and reliability of the cutting. It is conceivable that the second plate 320 is provided with a connecting frame 322, which has a clearance opening 323 for avoiding the first clamping member 410, allowing the first clamping member 410 to reciprocate along the clearance opening 323, improving the stability and smoothness of the operation.

[0071] In step S420, a cutting mechanism is used to cut the film strip. The cutting mechanism uses a non-contact laser die-cutting method to cut the film strip, eliminating the need for a die-cutting mold, thereby improving cutting accuracy and preventing deformation or damage to the film frame.

[0072] Furthermore, a first cutting groove 311 is formed between the first plate 310 and the second plate 320. A second cutting groove 312 is provided on the first plate 310 outside the first cutting groove 311. A receiving space adapted to the membrane frame is formed between the first cutting groove 311 and the second cutting groove 312. The first cutting groove 311 and the second cutting groove 312 form a clearance space for cutting, thereby improving the cutting quality and ensuring the quality of the membrane frame. After cutting is completed, the membrane frame is located in the receiving space, and the waste material in the middle of the membrane frame corresponds exactly to the second plate 320, thereby facilitating the discharge of the waste material in the middle of the membrane frame through the second plate 320.

[0073] Reference Figure 11 , Figure 11 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S150, which includes, but is not limited to, the following steps: Step S510: Drive the second plate 320 down, so that the second plate 320 carries the waste material in the middle of the membrane frame away from the first plate 310; Step S520: Drive the second plate 320 to slide, so that the second plate 320 leaves the membrane frame forming station; Step S530: Drive the first plate 310 down, so that the first plate 310 moves the membrane frame away from the membrane material strip; Step S540: Drive the first plate 310 to slide, so that the first plate 310 drives the membrane frame away from the membrane frame forming station.

[0074] Specifically, the second vertical moving unit 360 drives the second plate 320 to descend, causing the second plate 320 to carry the waste material away from the first plate 310. Then, the second horizontal moving unit 350 drives the second plate 320 to slide, causing the second plate 320 to leave the film frame forming station, thereby realizing the discharge of waste material. Then, the first vertical moving unit 340 drives the first plate 310 to descend, causing the first plate 310 to carry the film frame away from the film material strip. The first horizontal moving unit 330 drives the first plate 310 to slide, causing the first plate 310 to leave the film frame forming station, thereby realizing the transfer of the film frame.

[0075] In step S160, the lamination mechanism 200 is used to laminate the electrode and the membrane frame. Specifically, the surface of the membrane frame is provided with an adhesive layer, so only the membrane frame and the electrode need to be bonded together, without the need for heat pressing. Therefore, the lamination mechanism 200 includes a picking robot, which picks up the electrode from the storage area and transports it to the first plate 310, so that the electrode and the membrane frame are bonded together, making the lamination work simpler. Of course, in other embodiments, the surface of the membrane frame is not provided with an adhesive layer, in which case the membrane frame is laminated to the electrode by a heat pressing process.

[0076] Reference Figure 12 After completing step S160, the following is also included: Step S610: The electrode is tested by the testing agency 500.

[0077] The electrodes are tested by a testing agency of 500 to confirm the accuracy of the film frame and electrode lamination, thereby improving the quality of the electrodes.

[0078] Reference Figure 13 , Figure 13 yes Figure 12 A schematic diagram of an embodiment of the detailed process of step S610, which includes, but is not limited to, the following steps: Step S710: Convey the electrode sheet to the first receiving platform 530 or the second receiving platform 540; Step S720: Drive the first material receiving platform 530 and the second material receiving platform 540 to switch positions so that the first material receiving platform 530 or the second material receiving platform 540 corresponds to the detection component 510; Step S730: Inspect the electrode sheets on the first support platform 530 or the second support platform 540.

[0079] Specifically, the testing mechanism 500 includes a testing component 510, a flipping component 520, a first receiving platform 530, and a second receiving platform 540. The flipping component 520 is disposed on one side of the testing component 510. The first receiving platform 530 and the second receiving platform 540 are disposed vertically on one side of the testing direction of the testing component 510. The first receiving platform 530 and the second receiving platform 540 are respectively connected to the flipping component 520. The flipping component 520 drives the first receiving platform 530 and the second receiving platform 540 to switch positions.

[0080] After the electrode and membrane frame are laminated, the electrode is conveyed to the first receiving platform 530 or the second receiving platform 540. Then, the flipping assembly 520 drives the first receiving platform 530 and the second receiving platform 540 to switch positions. At this time, the first receiving platform 530 or the second receiving platform 540 corresponds to the detection assembly 510 for electrode detection. The other receiving platform is used for electrode unloading and loading for the next round of electrode detection. By adopting the above structure, electrode detection and electrode unloading can be realized simultaneously, shortening the electrode detection time and improving work efficiency.

[0081] The membrane frame forming, transfer and lamination method described in this application embodiment can realize the forming, transfer and lamination of the membrane frame, and can also realize the automatic discharge of waste materials, ensuring the integrity and stability of the membrane frame during the transfer process. Compared with the traditional transfer method that requires manual intervention, it can significantly improve the stability of the production cycle, reduce the risk of membrane frame deformation or damage caused by improper manual operation, improve the overall production efficiency, and ensure product quality.
