[0021] (2) Before the anode electrode is hot-pressed and laminated with the upper cathode electrode and the lower cathode electrode, it is confined in a relatively closed space made by the first and second diaphragms through the belt pressing roller assembly to prevent it from moving in the subsequent process and causing the product alignment to be out of tolerance;

[0022] (3) The first layer of anode plates and the second layer of anode plates are fed alternately into the belt-making roller assembly, which is more efficient than feeding by a single anode plate feeding mechanism;

[0023] (4) During the movement of the middle layer anode electrode group before it is combined with the upper layer cathode electrode group and the lower layer cathode electrode group, no other auxiliary transportation means such as upper and lower synchronous clamping belts or roller devices are required; therefore, the auxiliary transportation mechanism is reduced and the control process is simplified.

[0041] Working principle:

[0042] After the first layer of anode material strip 2 passes through the first layer of anode material strip roller assembly 104, it is rolled forward by the first feeding drive roller assembly 107. The first feeding motor 110 drives the first cutter assembly 108 and the first feeding clamp 109 to reciprocate. After the first feeding motor 110 moves forward at a speed that reaches the conveying speed of the first layer of anode material strip 2 and runs at the same speed, the first feeding clamp 109 clamps the first layer of anode material strip 2, and then the first cutter assembly 108 cuts the first layer of anode material strip 2 into the first layer of anode electrode sheet 21.

[0043] After the second layer of anode material strip 3 passes through the second layer of anode material strip roller assembly 105, it is rolled forward by the second feeding drive roller assembly 111. The second feeding motor 114 drives the second cutter assembly 112 and the second feeding clamp 113 to reciprocate. After the second feeding motor 114 moves forward at a speed that reaches the conveying speed of the second layer of anode material strip 3 and runs at the same speed, the second feeding clamp 113 clamps the second layer of anode material strip 3, and then the second cutter assembly 112 cuts the second layer of anode material strip 3 into the second layer of anode electrode sheet 31.

[0044] After the upper cathode material belt 6 passes through the upper cathode material belt roller assembly 201, it is rolled forward by the third feeding drive roller assembly 203. The third feeding motor 206 drives the third cutter assembly 204 and the third feeding clamp 205 to reciprocate. After the third feeding motor 206 moves forward at a speed that reaches the conveying speed of the upper cathode material belt 6 and runs at the same speed, the third feeding clamp 205 clamps the upper cathode material belt 6, and then the third cutter assembly 204 cuts the upper cathode material belt 6 into an upper cathode electrode sheet 61.

[0045] After the lower cathode material belt 7 passes through the lower cathode material belt roller assembly 202, it is rolled forward by the fourth feeding drive roller assembly 207. The fourth feeding motor 210 drives the fourth cutter assembly 208 and the fourth feeding clamp 209 to reciprocate. After the forward moving speed of the fourth feeding motor 210 reaches the conveying speed of the lower cathode material belt 7 and runs at the same speed, the fourth feeding clamp 209 clamps the lower cathode material belt 7, and then the fourth cutter assembly 208 cuts the lower cathode material belt 7 into the lower cathode electrode sheet 71.

[0046] The first anode electrode sheet 21 and the second anode electrode sheet 31 are alternately and evenly sandwiched forward, sandwiched between the first diaphragm 1 and the second diaphragm 4, and pulled forward by the tape-making roller assembly 102. In this process, the heated heating protrusion 1023 on the tape-making upper roller 1021 is pressed and laminated at the gap between the two adjacent electrode sheets, and the first diaphragm 1 and the second diaphragm 4 are laminated together, so that the two diaphragms form a relatively closed space, covering the anode electrode sheet therein.

[0047] After the anode electrode sheet coated with the diaphragm passes through the support plate 101, it reaches the feed roller assembly 301, and is sandwiched between the upper Mylar 9 and the lower Mylar 10 with the upper cathode electrode sheet 61 and the lower cathode electrode sheet 71, and enters the feed roller assembly 301, and then enters the first composite heating plate and the second composite heating plate for heating, and then is pressurized and composited by the composite roller assembly 303 to form a composite electrode group 8. Among them, the upper Mylar 9 and the lower Mylar 10 are rolled up by the external winding assembly under the action of the composite roller assembly 303.
