The composite film 930 is initially wound on the first unwinding roller 911, and under the rotation of the first unwinding roller 911, the unwinding of the composite film 930 is realized. The two ends of the material belt film 931 are connected with the first unwinding roller 911 and the first winding roller 912, respectively. The rotation of the first winding roller 912 can apply a traction force to the material belt film 931, so that the material belt film 931 passes through the forming mechanism 200.

[0092] Referring to Figure 4 , Figure 1 and Figure 2As shown, the polar sheet manufacturing device of the double-sided adhesive frame forms one surface of the polar sheet 1300 in the thickness direction through the forming mechanism 200, so that one surface of the polar sheet 1300 in the thickness direction is formed with an adhesive frame. In the manufacturing process of the solid-state battery, the polar sheet 1300 can be one of the positive polar sheet and the negative polar sheet. After the other one of the positive polar sheet and the negative polar sheet, the solid-state electrolyte layer, and the polar sheet 1300 are sequentially stacked, the other one of the positive polar sheet and the negative polar sheet is embedded in the adhesive frame, and the solid-state electrolyte layer is arranged between the positive polar sheet and the negative polar sheet. Through the surrounding and limiting of the adhesive frame, the transverse displacement of the solid-state electrolyte layer relative to the positive polar sheet or the negative polar sheet is avoided. Through the pressing of the positive polar sheet and the negative polar sheet, the bonding effect of the solid-state electrolyte layer and the positive polar sheet or the negative polar sheet is improved, so as to improve the forming quality of the solid-state battery.

[0093] Referring to Figure 4 , Figure 1 and Figure 2 , it can be understood that the positioning assembly 1000 includes a supporting plate 1010, a clamping plate 1020, and a closing and opening driver for driving the clamping plate 1020 to approach or move away from the supporting plate 1010. The clamping plate 1020 and the supporting plate 1010 can jointly clamp the material belt film 931.

[0094] Referring to Figure 4 , Figure 1 and Figure 2 , specifically, when the material belt film 931 passes through the positioning assembly 1000, the material belt film 931 passes through the gap between the clamping plate 1020 and the supporting plate 1010. The closing and opening driver of the polar sheet manufacturing device of the double-sided adhesive frame drives the clamping plate 1020 to approach the supporting plate 1010, so as to realize the joint clamping of the material belt film 931 by the clamping plate 1020 and the supporting plate 1010. In combination with the driving of the conveying assembly 1100, the material belt film 931 is pressed and conveyed. Through the joint clamping of the material belt film 931 by the clamping plate 1020 and the supporting plate 1010, the material belt film 931 can be limited in the transverse plane, so as to reduce the positioning error caused by the deviation of the composite film conveying mechanism 910 in the transverse plane, reduce the relative displacement of the polar sheet 1300 relative to the material belt film 931 in the conveying process, and accurately convey the polar sheet 1300 and the material belt film 931 to the forming mechanism 200 under the joint conveying of the composite film conveying mechanism 910 and the conveying assembly 1100, so as to form the polar sheet 1300 with the adhesive frame.

Taking the conveying direction of the material strip film 931 from left to right as an example, the two positioning components 1000 are respectively located on the front and rear sides of the material strip film 931. That is, the two positioning components 1000 can achieve cross clamping of the material strip film 931, which is beneficial to enhance the front and rear limit of the material strip film 931, thereby reducing the problem of front and rear offset of the material strip film 931 during the conveying process due to insufficient precision of the composite film conveying mechanism 910. This is beneficial to improve the positioning accuracy of the electrode 1300 and the material strip film 931 in the forming mechanism 200.

Both clamping plates 1020 are connected to the frame. The opening and closing driver is connected to the frame and the support plate 1010 to drive the frame to open and close relative to the support plate 1010. The arrangement of the two clamping plates 1020 helps to enhance the left and right positioning of the positioning component 1000 on the material strip film 931.

[0098] The two positioning components 1000 are named the first positioning component and the second positioning component, respectively. Figure 2 In the initial state, the first positioning component is located to the right of the second positioning component. After the first positioning component separates from the material strip film 931, under the driving action of the transfer component 1100, the first positioning component can move to the left of the second positioning component and achieve clamping of the material strip film 931. Figure 1 In state 2), under the driving action of the transfer component 1100, the first positioning component and the second positioning component together clamp the material strip film 931 and convey it to the right. Figure 2 In state 3), after the second positioning component separates from the tape film 931, under the driving action of the transfer component 1100, the second positioning component can move to the left of the first positioning component and clamp the tape film 931. Under the driving action of the transfer component 1100, the first positioning component and the second positioning component jointly clamp the tape film 931 and transport it to the right, thus completing one cycle.
