Description

Technical Field

[0001] This invention belongs to the technical field of production equipment for stacked batteries, and particularly relates to a cell stacking machine with a single power source. Background Technology

[0002] In secondary batteries such as lithium-ion batteries, the anode of the cell is made by coating both sides of aluminum foil with lithium-containing amorphous carbon powder. The cathode is made by coating both sides of copper foil with lithium iron phosphate powder or nickel manganese cobalt phosphate powder. The separator is made by coating one side of a polyolefin film with a ceramic particle layer, and then coating the other side of the ceramic particle layer and the polyolefin film with a polymer binder layer. The separator is densely covered with circular micropores that allow lithium ions to pass through, acting as a high-resistance special screen in the battery electrochemical system. A wound cell is prepared by stacking four layers (cathode, separator, anode, separator) together (with the ceramic particle layer of the separator facing the anode) through multiple layers. A laminated cell is prepared by stacking four layers (cathode, separator, anode, separator) together (with the ceramic particle layer of the separator facing the anode) through repeated stacking through multiple layers.

[0003] Laminated cells can eliminate the cylindrical corners of wound cells, increase the volume density of prismatic batteries, thus increasing the capacity of batteries of the same volume or reducing the volume of batteries of the same capacity. Laminated cells have begun to replace wound cells.

[0004] However, compared with wound cells, laminated cells have poor compactness, resulting in a larger volume of blank space and making them inconvenient to handle. Laminated cells also have a lower alignment pass rate and slower lamination speed (lower production capacity). Therefore, it is necessary to develop a high-speed cell lamination machine with high lamination quality, with the following requirements: overall diaphragm alignment ≤ ±0.5mm, adjacent electrode alignment ≤ ±0.3mm, overall electrode alignment ≤ ±0.5mm, and single-cell lamination time ≤ 0.35s (or single-cell lamination capacity ≥ 180PPM).

[0005] High-speed cell stacking machines require the coordination of multiple motion mechanisms, including picking up and placing anode sheets, picking up and placing cathode sheets, and stacking diaphragms. In the continuous, uninterrupted, and reciprocating high-speed motion, if multiple motion mechanisms use multiple power sources, it is difficult to achieve consistent motion, and disorder may even occur, affecting the stacking quality. Summary of the Invention

[0006] To meet the above requirements, the present invention provides a single-power-source cell stacking machine.

[0007] This invention is achieved by using a single-power-source cell stacking machine.

Located between the cathode sheet picking mechanism 310B and the cathode sheet placing mechanism 320B, the input end of the cathode sheet picking and placing transmission system 330B is connected to the first output end 631 of the transfer case 630, and the output end of the cathode sheet picking and placing transmission system 330B is connected to the cathode sheet picking mechanism 310B and the cathode sheet placing mechanism 320B respectively. The cathode sheet picking mechanism 310B and the cathode sheet placing mechanism 320B are arranged symmetrically in a mirror-image arrangement on the vertical plane of the rear plate 140B with the center of the cathode sheet picking and placing transmission system 330B.

[0081] Please see Figure 1The membrane laying device 400 is located in the diaphragm laying area 124 and is used to lay the diaphragm belt onto the anode plate and the cathode plate.

[0082] Please see Figure 2 The stacking device 500 is located in the anode stacking area 122A, the diaphragm arrangement area 124 and the cathode stacking area 122B, and is used to stack and press the anode plates, diaphragm strips and cathode plates layer by layer.

[0083] Please see Figure 1 The drive unit 600 includes a drive unit bracket 610, a drive component 620, and a transfer case 630. The drive unit bracket 610 is fixed to the frame 100. The drive component 620 and the transfer case 630 are both mounted on the drive unit bracket 610. The input end of the transfer case 630 is connected to the output end of the drive component 620. The first output end 631 of the transfer case 630 is connected to the anode plate picking and placing device 300A and the cathode plate picking and placing device 300B. The second output end 632 of the transfer case 630 is connected to the stacking device 500.

[0084] For further details, please see Figure 1-2 In this embodiment, the anode plate picking and placing device 300A and the cathode plate picking and placing device 300A are arranged symmetrically with mirrors facing each other between the center of the front frame and the rear frame of the support 130.

[0085] During the stacking process, when the anode sheet picking mechanism 310A picks up an anode sheet from the anode sheet feeding device 200A, the anode sheet placing mechanism 320A places the anode sheet onto the stacking device 500 that has moved to the anode sheet stacking area 122A. The cathode sheet picking mechanism 310B and the cathode sheet placing mechanism 320B then exchange cathode sheets. Simultaneously, when the anode sheet picking mechanism 310A and the anode sheet placing mechanism 320A exchange anode sheets, the cathode sheet picking mechanism 310B picks up a cathode sheet from the cathode sheet feeding device 200B, and the cathode sheet placing mechanism 320B places the anode sheet onto the stacking device 500 that has moved to the cathode sheet stacking area 122A. The stacking device 500 of 22B places the cathode sheet. During the process of the stacking device 500 moving from the anode sheet stacking area 122A to the cathode sheet stacking area 122B, it passes through the diaphragm placement area 124. The membrane placement device 400 places a diaphragm on the anode sheet. During the process of the stacking device 500 moving from the cathode sheet stacking area 122B to the anode sheet stacking area 122A, it passes through the diaphragm placement area 124 again. The membrane placement device 400 places another diaphragm on the cathode sheet. This process continues without interruption until a preset number of anode sheets, diaphragms and cathode sheets are stacked to complete the stacking of one cell.

[0086] In other embodiments, the anode sheet picking and placing device 300A and the cathode sheet picking and placing device 300B are arranged symmetrically with respect to the center plane between the left and right frames of the support 130. The film placing device 400 is positioned above the left and right frames. The stacking device 500 is positioned below the anode sheet picking and placing device 300A, the film placing device 400, and the cathode sheet picking and placing device 300B. The stacking device 500 passes below the film placing device 400 and continuously moves back and forth between the anode sheet picking and placing device 300A and the cathode sheet picking and placing device 300B without interruption until a preset number of anode sheets, separators, and cathode sheets are stacked to complete the stacking of one cell.

The anode sheet picking transmission assembly 311A ​​is located on the front left side of the front upright plate 140A, and the anode sheet picking suction cup assembly 312A is fixed to the output end of the anode sheet picking transmission assembly 311A.

The anode sheet placing transmission assembly 321A is located on the front right side of the front upright plate 140A, and the anode sheet placing suction cup assembly 322A is fixed to the output end of the anode sheet placing transmission assembly 321A.

The first fixed rotating shaft 3117, the second fixed rotating shaft 3118, and the third fixed rotating shaft 3119 of the anode sheet picking transmission assembly 311A, and the first fixed rotating shaft 3117, the second fixed rotating shaft 3118, and the third fixed rotating shaft 3119 of the anode sheet placing transmission assembly 321A are all fixed to the corresponding positions on the front upright plate 140A. The first fixed rotating shaft 3117, the second fixed rotating shaft 3118, and the third fixed rotating shaft 3119 of the cathode sheet picking transmission assembly 311B, and the first fixed rotating shaft 3117, the second fixed rotating shaft 3118, and the third fixed rotating shaft 3119 of the cathode sheet placing transmission assembly 321B are all fixed to the corresponding positions on the front upright plate 140A. 8 and the third fixed rotating shaft 3119 are both fixed to the corresponding positions of the rear upright plate 140B. The first fixed rotating shaft 3117 is connected to the anode plate picking and placing transmission system 330A or the cathode plate picking and placing transmission system 330B. The transmission connecting rod drive 3112 is fixed on the first fixed rotating shaft 3117. The transmission connecting rod driven 3113 is rotatably sleeved on the second fixed rotating shaft 3118 through the first connection point 31131. The transmission rotary plate 3116 is fixed on the third fixed rotating shaft 3119. The first floating rotating shaft 311a is connected between the transmission connecting rod drive 3112 and the transmission connecting rod 3111. The second floating rotating shaft 311a is connected to the third fixed rotating shaft 3119. The rotating shaft 311b is connected between the transmission connecting rod 3111 and the second transmission connection point 31132 of the transmission connecting rod follower 3113.

The anode sheet picking suction cup assembly 312A, the anode sheet placing suction cup assembly 322A, the cathode sheet picking suction cup assembly 312B, and the cathode sheet placing suction cup assembly 322B are respectively fixed on the corresponding slide plate 3114.

[0093] Please see further. Figure 3 The anode sheet placement drive assembly 321A and the anode sheet picking drive assembly 311A ​​are arranged mirror-symmetrically on the left and right sides of the vertical plane of the front upright plate 140A with the center of the anode sheet picking and placing drive system 330A; please refer to further details. Figure 1The cathode plate placement drive assembly 321B and the cathode plate picking drive assembly 311B are arranged mirror-symmetrically on the left and right sides of the vertical plane of the rear upright plate 140B with the center of the cathode plate picking and placing drive system 330B. Since the anode plate placement drive assembly 321A and the anode plate picking drive assembly 311A ​​have the same structure and are mirror-symmetrical, their transmission principle is the same as that of the anode plate picking drive assembly 311A, but their movement direction is opposite, and will not be described in detail here.

[0094] The structures of the cathode sheet picking drive assembly 311B and the cathode sheet placing drive assembly 321B are the same as those of the anode sheet picking drive assembly 311A ​​and the anode sheet placing drive assembly 321A, and are arranged in a mirror-symmetrical manner. Therefore, the transmission principle of the cathode sheet picking drive assembly 311B and the cathode sheet placing drive assembly 321B is the same as that of the anode sheet picking drive assembly 311A ​​and the anode sheet placing drive assembly 321A, and the picking and placing can be staggered in opposite directions. This will not be elaborated here.

[0095] The drive unit 620 can perform alternating and continuous anode plate picking and placing and anode plate handover, as well as cathode plate picking and placing and cathode plate handover by rotating continuously in one direction.

[0096] In this embodiment, please refer to Figure 4 The anode sheet picking suction cup assembly 312A, the anode sheet placing suction cup assembly 322A, the cathode sheet picking suction cup assembly 312B, and the cathode sheet placing suction cup assembly 322B all include a suction cup frame 3121, a suction cup connecting rod 3122, a suction cup mounting plate 3123, and a suction cup 3124. The suction cup frame 3121 is fixed on the transmission slide plate 3114, one end of the suction cup connecting rod 3122 is fixed on the suction cup frame 3121, one side of the suction cup mounting plate 3123 is fixed to the other end of the suction cup connecting rod 3122, and the suction cup 3124 is fixed to the other side of the suction cup mounting plate 3123.

[0097] In this embodiment, please refer to Figure 1 The anode plate loading and unloading transmission system 330A is fixed to the rear of the front upright plate 140A; please refer to Figure 2 The cathode plate loading and unloading transmission system 330B is fixed to the front of the rear upright plate 140B.

[0098] In this embodiment, please refer to Figure 5 and Figure 11Both the anode plate pick-and-place transmission system 330A and the cathode plate pick-and-place transmission system 330B include a pick-and-place drive wheel 331, a pick-and-place transmission belt 332, a first driven pulley shaft 333, a first driven pulley 334, a first transmission gear 335, a second transmission gear 336, a third transmission gear 337, a transmission reversing gear fixed shaft 338, and a transmission reversing gear 339. The pick-and-place drive wheel 331 of the anode plate pick-and-place transmission system 330A and the pick-and-place drive wheel 331 of the cathode plate pick-and-place transmission system 330B are fixed to the first output end 631 of the transfer case 630. The first driven pulley shaft 333 and the transmission reversing gear fixed shaft 338 are fixed to the middle of the back of the front upright plate 140A or the rear upright plate 140B. The first driven pulley 334 and... The first transmission gears 335 are all fixed on the first transmission driven wheel shaft 333. The pick-and-place transmission belt 332 passes through the second through groove 126 or the third through groove 127 of the panel 120 and is sleeved on the pick-and-place driving wheel 331 and the first transmission driven wheel 334. The second transmission gear 336 is fixed on the first fixed shaft 3117 of the anode sheet pick-and-place transmission assembly 311A ​​or the first fixed shaft 3117 of the cathode sheet pick-and-place transmission assembly 311B. The third transmission gear 337 is fixed on the first fixed shaft 3117 of the anode sheet placement transmission assembly 321A or the first fixed shaft 3117 of the cathode sheet placement transmission assembly 321B. The transmission reversing gear 339 is fixed on the transmission reversing gear fixed shaft 338.

[0099] The second transmission gear 336 meshes with the first transmission gear 335, the third transmission gear 337 does not mesh with the first transmission gear 335, and the transmission reversing gear 339 meshes with both the third transmission gear 337 and the first transmission gear 335; or, the third transmission gear 337 meshes with the first transmission gear 335, the second transmission gear 336 does not mesh with the first transmission gear 335, and the transmission reversing gear 339 meshes with both the second transmission gear 336 and the first transmission gear 335.

[0100] It should be noted that for the same take-up and put-down drive wheel 331, if the second transmission gear 336 and the third transmission gear 337 directly mesh with the first transmission gear 335, they will also rotate clockwise in the same direction. However, as long as they are indirectly meshed through the transmission reversing gear 339, the second transmission gear 336 and the third transmission gear 337 can be reversed to rotate counterclockwise. Therefore, selecting either the second transmission gear 336 or the third transmission gear 337 to mesh with the transmission reversing gear 339, while leaving the other unmeshed, can achieve the opposite rotation of the symmetrically arranged plate-picking transmission assembly 311 and plate-laying transmission assembly 321 to synchronously pick up and place, as well as exchange and connect, anode or cathode plates. Whether to select the second transmission gear 336 or the third transmission gear 337 to mesh with the transmission reversing gear 339 depends on the rotation requirements of the pick-up and place-down drive wheel 331. For example, clockwise rotation viewed from the front of the vertical plate may be used for connecting electrode plates or picking up and placing electrode plates. If it is used for connecting electrode plates, then the third transmission gear 337 is selected to mesh with the transmission reversing gear 339; if it is used for picking up and placing electrode plates, then the second transmission gear 336 is selected to mesh with the transmission reversing gear 339.

[0101] The process of placing and removing the anode sheet is as follows:

[0102] Anode plate pick-and-place drive: The initial state is when the anode plate handover is just completed. Please refer to [link / reference]. Figure 9 The termination state is when the anode plate can be just removed and placed. Please refer to [link / reference]. Figure 7 See the rear view from the front panel 140A. Figure 6 and Figure 5 The drive unit 620 drives the first output end 631 of the transfer case 630 to rotate clockwise with the pick-up drive wheel 331 of the anode plate pick-up and place transmission system 332. The pick-up drive wheel 331 drives the pick-up transmission belt 332 to rotate clockwise, which in turn drives the first driven wheel 334 to rotate clockwise. The first driven wheel 334 drives the first transmission gear 335 to rotate clockwise. The first transmission gear 335 then drives the second transmission gear 336 to rotate counterclockwise. At the same time, the first transmission gear 335 also drives the transmission reversing gear 339 to rotate counterclockwise. The transmission reversing gear 339 then drives the third transmission gear 337 to rotate clockwise. That is, the counterclockwise rotation of the anode plate pick-up and place transmission system 332 to the second transmission gear 336 and the clockwise rotation to the third transmission gear 337 are opposite in direction, providing power for picking up and placing anode plates or transferring anode plates.

[0103] For anode plate removal: please refer to [link / reference]. Figure 7 and Figure 4The device has been moved to the state where it can pick up and place wafers. Both are viewed from the front of the front upright plate 140A. On the left, the first transmission fixed shaft 3117 of the anode wafer picking transmission assembly 311A ​​rotates clockwise under the drive of the second transmission gear 336. The first transmission fixed shaft 3117 drives the transmission connecting rod drive 3112 to rotate clockwise to the left, causing one end of the transmission connecting rod 3111 connected to the transmission connecting rod drive 3112 and the first transmission floating shaft 311a to rotate clockwise to the left with the transmission connecting rod drive 3112. This pushes the other end of the transmission connecting rod 3111, its second transmission connection point 31132 connected to the transmission connecting rod driven member 3113, and the second transmission floating shaft 311b to rotate counterclockwise to the left around the second transmission fixed shaft 3118, causing the transmission connecting rod... The third transmission connection point 31133 of the driven member 3113 rotates counterclockwise to the left around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move the suction cup 3124 of the anode sheet picking suction cup assembly 312A to the upper left to leave the suction cup 3124 of the anode sheet placement suction cup assembly 322A, and drive the transmission rotary plate 3116 to rotate clockwise around the third transmission fixed shaft 3119, causing the anode sheet picking suction cup assembly 312A to leave the anode sheet junction area 123A with the suction cup 3124; until the third transmission connection point 31133 comes to the line connecting the second transmission fixed shaft 3118 and the third transmission fixed shaft 3119, the transmission slide plate 3114 takes the anode sheet picking suction cup assembly 312A to the leftmost and uppermost position;

[0104] Please continue reading Figure 7 and Figure 4 Looking from the front of the front upright plate 140A, the first transmission fixed shaft 3117 of the anode sheet picking transmission assembly 311A ​​on the left continues to rotate clockwise to the left under the drive of the second transmission gear 336. This drives the third transmission connection point 31133 of the transmission linkage follower 3113 to rotate counterclockwise to the left around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move the anode sheet picking suction cup assembly 312A to the lower right and drive the transmission rotary plate 3116 to continue rotating clockwise around the third transmission fixed shaft 3119. This continues until the transmission slide plate 3114 and the anode sheet picking suction cup assembly 312A are in a vertical position and at the far right and bottom position, allowing the suction cup 3124 to descend to the picking area 121 to pick up the anode sheet.

[0105] Placing the anode plate: This is done in the same way as removing the anode plate, only the direction of movement is reversed and the left-right direction is reversed; the up-down direction remains the same.

[0106] Please see 7 and Figure 4The device has moved to the position where it can pick up and place the wafer. Both positions are viewed from the front of the front upright plate 140A. The first fixed shaft 3117 of the wafer picking transmission assembly 321 on the right rotates counterclockwise under the drive of the third transmission gear 337. The first fixed shaft 3117 drives the transmission link drive 3112 to rotate counterclockwise to the right, causing one end of the transmission link 3111 connected to the transmission link drive 3112 and the first floating shaft 311a to rotate counterclockwise to the right with the transmission link drive 3112. This pushes the other end of the transmission link 3111 and its second transmission connection point 31132 connected to the transmission link driven member 3113, as well as the second floating shaft 311b, to rotate clockwise to the right around the second fixed shaft 3118, causing the transmission link driven member... The third transmission connection point 31133 of component 3113 rotates clockwise to the right around the second transmission fixed shaft 3118 with the third transmission floating shaft 311c. This causes the transmission slide plate 3114 to move the suction cup 3124 of the anode sheet pick-up suction cup assembly 312A to the upper right to leave the suction cup 3124 of the anode sheet placement suction cup assembly 322A. It also drives the transmission rotary plate 3116 to rotate counterclockwise around the third transmission fixed shaft 3119, causing the anode sheet placement suction cup assembly 322A to leave the anode sheet junction area 123A with the suction cup 3124. This continues until the third transmission connection point 31133 reaches the line connecting the second transmission fixed shaft 3118 and the third transmission fixed shaft 3119. The transmission slide plate 3114 then moves the anode sheet placement suction cup assembly 322A to the rightmost and uppermost position.

[0107] Please continue to see section 7 and... Figure 4 Looking from the front of the front upright plate 140A, the first transmission fixed shaft 3117 of the anode sheet placement transmission assembly 321A on the right continues to rotate counterclockwise under the drive of the second transmission gear 336. This drives the third transmission connection point 31133 of the transmission linkage follower 3113 to rotate clockwise to the right around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move to the lower left with the sheet placement suction cup assembly 322 and drive the transmission rotary plate 3116 to continue rotating counterclockwise around the third transmission fixed shaft 3119. This continues until the transmission slide plate 3114 and the sheet placement suction cup assembly 322 become vertical and are in the leftmost and lowermost position, allowing the suction cup 3124 to descend to the anode sheet stacking area 122A to place the anode sheet.

[0108] The anode plate handover process is as follows, and the rotation direction is opposite to that of the anode plate removal and placement process:

[0109] Anode plate handover drive: The initial state is when the anode plate pick-up and drop-off is just completed. Please refer to [link / reference]. Figure 7 The termination state is when the anode plate can just be connected and the anode plate can be joined. Please refer to [link / reference]. Figure 9 See the rear view from the front panel 140A. Figure 8 and Figure 5 The drive unit 620 drives the first output end 631 of the transfer case 630 to rotate counterclockwise with the anode plate pick-and-place drive wheel 331 of the anode plate pick-and-place transmission system 332. The pick-and-place drive wheel 331 drives the pick-and-place transmission belt 332 to rotate counterclockwise, which in turn drives the first driven pulley 334 to rotate counterclockwise. The first driven pulley 334 drives the first transmission gear 335 to rotate clockwise, and the first transmission gear 335 then drives the second transmission gear 336 to rotate clockwise. At the same time, the first transmission gear 335 also drives the transmission reversing gear 339 to rotate clockwise, and the transmission reversing gear 339 then drives the third transmission gear 337 to rotate counterclockwise. That is, the clockwise rotation of the anode plate pick-and-place transmission system 332 to the second transmission gear 336 and the counterclockwise rotation to the third transmission gear 337 are opposite in direction, providing power for picking up or placing anode plates or transferring anode plates.

[0110] Anode plate replacement: The rotation direction is opposite to that during the anode plate removal process. Please refer to [link to relevant documentation]. Figure 9 and Figure 4 The components have been moved to the states where they can be exchanged and joined. Viewed from the front of the front upright plate 140A, the first transmission fixed shaft 3117 of the left-side interlocking transmission assembly 311 rotates counterclockwise under the drive of the second transmission gear 336. The first transmission fixed shaft 3117 drives the transmission connecting rod drive member 3112 to rotate counterclockwise to the right. This causes one end of the transmission connecting rod 3111 connected to the transmission connecting rod drive member 3112, as well as the first transmission floating shaft 311a, to rotate counterclockwise to the right with the transmission connecting rod drive member 3112. This pushes the other end of the transmission connecting rod 3111, its second transmission connection point 31132 connected to the transmission connecting rod driven member 3113, and the second transmission floating shaft 311b to rotate clockwise to the right around the second transmission fixed shaft 3118. The transmission connecting rod drives the third transmission connection point 31133 of the driven member 3113 to rotate the third transmission floating shaft 311c clockwise around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move the suction cup 3124 of the anode sheet picking suction cup assembly 312A to move to the upper left to leave the outer anode sheet basket, and also drives the transmission rotary plate 3116 to rotate counterclockwise around the third transmission fixed shaft 3119, causing the anode sheet picking suction cup assembly 312A to leave the picking area 121 with the suction cup 3124; until the third transmission connection point 31133 comes to the line connecting the second transmission fixed shaft 3118 and the third transmission fixed shaft 3119, the transmission slide plate 3114 carries the anode sheet picking suction cup assembly 312A to the leftmost and uppermost position;

[0111] Please continue reading Figure 9 and Figure 4Looking from the front of the front plate 140A, the first transmission fixed shaft 3117 of the anode sheet picking transmission assembly 311A ​​on the left continues to rotate counterclockwise to the right under the drive of the second transmission gear 336. This drives the third transmission connection point 31133 of the transmission linkage follower 3113 to rotate clockwise to the right around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move to the lower right with the sheet picking suction cup assembly 312A and drive the transmission rotary plate 3116 to continue rotating counterclockwise around the third transmission fixed shaft 3119. This continues until the transmission slide plate 3114 and the anode sheet picking suction cup assembly 312A are in a horizontal position and at the far right and bottom position, allowing the suction cup 3124 to move to the right to the anode sheet junction area 123A to pick up the anode sheet.

[0112] Connecting the anode plate: The rotation direction is opposite to that during the process of placing the anode plate.

[0113] Please see Figure 9 and Figure 4 The device has moved to the state where it can exchange and connect pieces. Both are viewed from the front of the front upright plate 140A. The first fixed shaft 3117 of the right-hand piece-picking transmission assembly 321 rotates clockwise under the drive of the third transmission gear 337. The first fixed shaft 3117, along with the transmission linkage drive member 3112, rotates clockwise to the right. This causes one end of the transmission linkage 3111 connected to the transmission linkage drive member 3112, as well as the first floating shaft 311a, to rotate clockwise to the right with the transmission linkage drive member 3112. This pushes the other end of the transmission linkage 3111, its second transmission connection point 31132 connected to the transmission linkage follower 3113, and the second floating shaft 311b to rotate counterclockwise to the right around the second fixed shaft 3118. The transmission connecting rod, driven by the third transmission connection point 31133 of the driven member 3113, rotates the third transmission floating shaft 311c counterclockwise around the second transmission fixed shaft 3118 to the right. This causes the transmission slide plate 3114 to move the suction cup 3124 of the anode sheet placement suction cup assembly 322A to the upper right to leave the external stacking platform. It also drives the transmission rotary plate 3116 to rotate clockwise around the third transmission fixed shaft 3119, causing the anode sheet placement suction cup assembly 322A to leave the stacking area 122 with the suction cup 3124. This continues until the third transmission connection point 31133 reaches the line connecting the second transmission fixed shaft 3118 and the third transmission fixed shaft 3119, at which point the transmission slide plate 3114 moves the anode sheet placement suction cup assembly 322A to the rightmost and uppermost position.

[0114] Please continue reading Figure 9 and Figure 4Looking from the front of the front plate 140A, the first transmission fixed shaft 3117 of the anode sheet placement transmission assembly 321A on the right continues to rotate clockwise under the drive of the second transmission gear 336. This drives the third transmission connection point 31133 of the transmission connecting rod follower 3113 to rotate counterclockwise to the right around the second transmission fixed shaft 3118, causing the transmission slide plate 3114 to move to the lower left with the anode sheet placement suction cup assembly 322A and drive the transmission rotary plate 3116 to continue rotating clockwise around the third transmission fixed shaft 3119. This continues until the transmission slide plate 3114 and the anode sheet placement suction cup assembly 322A are in a horizontal position and at the leftmost and lowest position, allowing the suction cup 3124 to move to the left and into the anode sheet junction area 123A to receive the anode sheet.

[0115] The process of placing and removing the cathode plate is exactly the same as that of placing and removing the anode plate.

[0116] The anode plate picking and placing transmission system 330A drives the second transmission gear 336 and the third transmission gear 337 in opposite directions, so that the driving member 620 can simultaneously drive the anode plate picking mechanism 310A with the suction cup 3124 and the anode plate placing mechanism 320A with the suction cup 3124 to rotate in opposite directions to pick up, place and transfer anode plates; the cathode plate picking and placing transmission system 330B drives the second transmission gear 336 and the third transmission gear 337 in opposite directions, so that the driving member 620 can simultaneously drive the cathode plate picking mechanism 310B with the suction cup 3124 and the cathode plate placing mechanism 320B with the suction cup 3124 to rotate in opposite directions to pick up, place and transfer cathode plates.

[0117] The anode plate picking and placing device 300A and the cathode plate picking and placing device 300B are arranged in a linear left-right combination or back-to-back front-back combination, so that the anode plate picking and placing or anode plate handover of the anode plate picking and placing device 300A and the cathode plate handover or cathode plate picking and placing of the cathode plate picking and placing device 300B are carried out simultaneously. The anode plate picking and placing device 300A and the cell cathode plate picking and placing device 300B are combined into a composite picking and placing device in which anode plates and cathode plates are alternately stacked.

[0118] Please see further. Figure 10 The film feeding device 400 includes a film feeding bracket 410, a film roll tensioning assembly 420, a film guide roller 430, a film tensioning assembly 440, and a film clamping assembly 450. The film feeding bracket 410 is fixed on the bracket 130. The film roll tensioning assembly 420, the film guide roller 430, the film tensioning assembly 440, and the film clamping assembly 450 are all fixed on the film feeding bracket 410. The film guide roller 430, the film tensioning assembly 440, and the film clamping assembly 450 are all located in the film feeding channel 131 of the bracket 130. The film roll tensioning assembly 420 is used to feed the diaphragm belt roll on the outer sleeve. The diaphragm belt passes through the film guide roller 430, the film tensioning assembly 440, and the film clamping assembly 450 in sequence, and finally extends into the stacking platform in the diaphragm laying area 124.

[0119] Understandably, the stacking stage 500 moves to the diaphragm placement area 124 in the initial state, and the membrane placement device 400 places a diaphragm layer onto the stacking area 515 of the stacking stage 500. The first diaphragm layer moves with the stacking stage 500 to the anode stacking area 122A to receive the first anode sheet and be pressed down by it. The stacking stage 500 then moves through the diaphragm placement area 124 to the cathode stacking area 122B. The diaphragm belt tensioning assembly 420 rotates to release the diaphragm belt, and the diaphragm belt is folded by the membrane clamping assembly 450 to cover the first anode sheet. The first cathode sheet is pressed onto the second diaphragm in the stacking stage 500, which then returns to the anode sheet stacking area 122A via the diaphragm placement area 124. The diaphragm strip is folded over the first cathode sheet to become the third diaphragm. The second anode sheet is then placed onto the third diaphragm in the same manner. This process is repeated continuously and without interruption until a preset number of anode sheets, diaphragms, and cathode sheets are stacked to complete the stacking of one cell. This process does not require cutting the diaphragm strip and speeds up the diaphragm placement process.

[0124] In this embodiment, please refer to Figure 12-14 The anode pressing mechanism 530A includes an anode pressing rotary drive 531, an anode pressing transmission system 532, two left and right anode pressing transmission assemblies 533, and two left and right anode pressing palms 534A. The anode pressing rotary drive 531 and the anode pressing transmission system 532 are both disposed on the inner surface of the front panel 512 of the platform. The input end of the anode pressing transmission system 532 is disposed at the output end of the anode pressing rotary drive 531. The two left and right anode pressing transmission assemblies 533 are both fixed on the outer surface of the front panel 512 of the platform and are arranged mirror-symmetrically on the left and right sides of the vertical plane of the middle of the front panel 512. The input ends of the two left and right anode pressing transmission assemblies 533 are both disposed at the output end of the anode pressing transmission system 532. The two left and right anode pressing palms 534A are respectively fixed at the output ends of the two left and right anode pressing transmission assemblies 533 and are used to press the two ends of the anode sheets respectively.

[0125] The structure of the cathode pressing mechanism 530B is exactly the same as that of the anode pressing mechanism 530A. It includes a cathode pressing rotary drive, a cathode pressing transmission system, two left and right cathode pressing transmission assemblies, and two left and right cathode pressing palms 534B. The cathode pressing rotary drive and the cathode pressing transmission system are both located on the inner surface of the rear panel 513 of the stage. The input end of the cathode pressing transmission system is located at the output end of the cathode pressing rotary drive. The two left and right cathode pressing transmission assemblies are fixed on the outer surface of the rear panel 513 of the stage and are arranged symmetrically with respect to the vertical plane of the middle of the rear panel 513 of the stage. The input ends of the two left and right cathode pressing transmission assemblies are both located at the output end of the cathode pressing transmission system. The two left and right cathode pressing palms 534B are respectively fixed at the output ends of the two left and right cathode pressing transmission assemblies and are used to press the two ends of the cathode sheet.

[0126] The anode pressing mechanism 530A and the cathode pressing mechanism 530B alternately press and release the anode sheet. When the stacking stage drive system 524 drives the stacking stage 510 to move from front to back, the two anode sheet pressing palms 534A of the anode pressing mechanism 530A on the front panel 512 of the stage press the two ends of the anode sheet, and the two cathode sheet pressing palms 534B of the cathode pressing mechanism 530B on the rear panel 513 of the stage release the anode sheet. When the stacking stage drive system 524 drives the stacking stage 510 to move from back to front, the two anode sheet pressing palms 534A of the anode pressing mechanism 530A on the front panel 512 of the stage release the cathode sheet, and the two cathode sheet pressing palms 534B of the cathode pressing mechanism 530B on the rear panel 513 of the stage press the cathode sheet.

[0127] Please see further. Figure 12 Both the anode pressing and straightening transmission system 532 and the cathode pressing and straightening transmission system include a pressing and straightening drive gear 5321, a first pressing and straightening gear shaft 5323, a first pressing and straightening gear 5325, a second pressing and straightening gear 5326, a third pressing and straightening gear 5327, a pressing and straightening reversing gear fixed shaft 5328, and a reversing gear 5329. The pressing and straightening drive gear 5321 is fixed to the output end of the anode rotating drive member 531 or the cathode pressing and straightening rotating drive member. The first pressing and straightening gear shaft 5323 and the pressing and straightening reversing gear fixed shaft 5328 of the anode pressing and straightening transmission system 532 are fixed on the platform. At the center of the inner surface of the front panel 512, the first pressing gear shaft 5323 and the pressing reversing gear fixed shaft 5328 of the cathode sheet pressing and straightening transmission system are fixed at the center of the inner surface of the rear panel 513 of the platform. The first pressing gear 5325 is fixed on the first pressing gear shaft 5323. The second pressing gear 5326 and the third pressing gear 5327 are respectively fixed on the left and right anode sheet pressing and straightening transmission assemblies 533 or the left and right cathode sheet pressing and straightening transmission assemblies. The reversing gear 5329 is fixed on the pressing reversing gear 5329 fixed shaft 5328.

[0128] The second pressing gear 5326 meshes with the first pressing gear 5325, the third pressing gear 5327 does not mesh with the first pressing gear 5325, and the reversing gear 5329 meshes with both the third pressing gear 5327 and the first pressing gear 5325; or, the third pressing gear 5327 meshes with the first pressing gear 5325, the second pressing gear 5326 does not mesh with the first pressing gear 5325, and the reversing gear 5329 meshes with both the second pressing gear 5326 and the first pressing gear 5325.

[0129] The anode pressing and straightening transmission system 532 transmits power to the second pressing and straightening gear 5326 and the third pressing and straightening gear 5327 in opposite directions, so that the anode pressing and straightening rotary drive 531 can simultaneously drive the left and right anode pressing and straightening transmission assemblies 533 to rotate in opposite directions with the two anode pressing palms 534A; the cathode pressing and straightening transmission system transmits power to the second pressing and straightening gear 5326 and the third pressing and straightening gear 5327 in opposite directions, so that the cathode pressing and straightening rotary drive can simultaneously drive the left and right cathode pressing and straightening transmission assemblies to rotate in opposite directions with the two cathode pressing palms 534B.

[0130] It should be noted that the use of the reversing gear 5329 can realize the reverse movement of the second pressing gear 5326 and the third pressing gear 5327, thereby realizing the symmetrically arranged anode pressing transmission system 532 and cathode pressing transmission system to complete the symmetrical operation. Therefore, the reversing gear 5329 can mesh with the second pressing gear 5326 or with the third pressing gear 5327.

[0131] In this embodiment, please refer to Figure 4The left and right anode sheet pressing and straightening transmission assemblies 533 and the left and right cathode sheet pressing and straightening transmission assemblies each include a pressing and straightening connecting rod 5331, a pressing and straightening connecting rod driving member 5332, a pressing and straightening connecting rod driven member 5333, a pressing and straightening sliding plate 5334, a pressing and straightening sliding block 5335, a pressing and straightening rotary plate 5336, a first pressing and straightening fixed rotating shaft 5337, a second pressing and straightening fixed rotating shaft 5338, a third pressing and straightening fixed rotating shaft 5339, a first pressing and straightening floating rotating shaft 533a, a second pressing and straightening floating rotating shaft 533b, and a third pressing and straightening floating rotating shaft 533c. The pressing and straightening connecting rod driven member 5333 includes three connection points. The pressing and straightening connecting rod driving member 5332 is fixed to the first pressing and straightening fixed rotating shaft 5337, and the pressing and straightening connecting rod driven member 5333 is connected to the first pressing and straightening fixed rotating shaft 5337.

[0132] The first pressing and fixing shaft 5337, the second pressing and fixing shaft 5338, and the third pressing and fixing shaft 5339 of the left and right anode pressing and straightening transmission assemblies 533 are all fixed on the outer surface of the front panel 512 of the platform. The left and right first pressing and fixing shafts 5337 of the left and right anode pressing and straightening transmission assemblies 533 respectively provide for fixing the second pressing and straightening gear 5326 and the third pressing and straightening gear 5327 of the anode pressing and straightening transmission system 530A.

[0133] The first pressing and fixing shaft 5337, the second pressing and fixing shaft 5338, and the third pressing and fixing shaft 5339 of the left and right cathode sheet pressing and fixing transmission assemblies are all fixed on the outer surface of the rear panel 513 of the platform. The left and right first pressing and fixing shafts 5337 of the left and right cathode sheet pressing and fixing transmission assemblies respectively provide the second pressing gear 5326 and the third pressing gear 5327 of the cathode sheet pressing and fixing transmission system 530B for fixing.

[0134] The anode plate presser 534A is fixed on the pressing slide plate 5334 of the anode plate pressing transmission assembly 533.

[0135] The cathode plate press 534B is fixed on the pressing slide plate 5334 of the cathode plate pressing transmission assembly.

[0136] Please see further. Figure 14The anode pressing mechanism 530A and the cathode pressing mechanism 530B alternately press and release the anode sheet. When the stacking platform drive system 524 drives the stacking platform 510 to move from front to back, the left and right anode sheet pressing hands 534A of the anode sheet pressing mechanism 530A on the front panel 512 of the platform press the edges of both ends of the anode sheet, and the left and right cathode sheet pressing hands 534B of the cathode sheet pressing mechanism 530B on the rear panel 513 of the platform release the anode sheet. When the stacking platform drive system 524 drives the stacking platform 510 to move from back to front, the left and right anode sheet pressing hands 534A of the anode sheet pressing mechanism 530A on the front panel 512 of the platform release the cathode sheet, and the left and right cathode sheet pressing hands 534B of the cathode sheet pressing mechanism 530B on the rear panel 513 of the platform press the edges of both ends of the cathode sheet.

[0137] The anode sheet pressing process is as follows:

[0138] Anode sheet pressing and straightening drive: Initially, the two pressing slides 5334 are horizontal, and the two anode sheet pressing pads 534A are located on the left and right sides of the stacking platform 510. The final state is that the stacking platform 510 is located in the anode sheet stacking area 124. After the anode sheets are stacked, the two pressing slides 5334 are vertical, and the two anode sheet pressing pads 534A are located on the top surface of the stacking platform 510, pressing down on the left and right sides of the anode sheets on the stacking area 515. Please refer to [link / reference]. Figure 2 and Figure 3 Looking from behind the front panel 512 of the platform, the anode sheet pressing and rotating drive 531 drives the pressing and rotating drive gear 5321 to rotate counterclockwise, which in turn drives the first pressing and rotating gear 5325 to rotate clockwise, and then drives the second pressing and rotating gear 5326 to rotate counterclockwise. At the same time, the first pressing and rotating gear 5325 also drives the pressing and rotating reversing gear 5329 to rotate counterclockwise. The pressing and rotating reversing gear 5329 then drives the third pressing and rotating gear 5327 to rotate clockwise. That is, the counterclockwise rotation of the anode sheet pressing and rotating drive system 532 to the second pressing and rotating gear 3326 and the clockwise rotation of the third pressing and rotating gear 3327 are opposite in direction, providing power for the left and right anode sheet pressing palms 534A to press and rotate the anode sheets and release the pressing and rotating anode sheets.

[0139] Anode pressing and straightening: Please refer to 14. The anode has been moved to the pressing and straightening position. To view it from the front of the front panel 512 of the platform, the first pressing and straightening fixed shaft 5337 of the left anode pressing and straightening transmission assembly 533 rotates clockwise under the drive of the second pressing and straightening gear 3326. The first pressing and straightening fixed shaft 5337 drives the pressing and straightening connecting rod drive member 5332 to rotate clockwise to the left. This drives one end of the pressing and straightening connecting rod 5331 connected to the pressing and straightening connecting rod drive member 5332 and the first pressing and straightening floating shaft 533a to rotate clockwise to the left with the pressing and straightening connecting rod drive member 5332. This pushes the other end of the pressing and straightening connecting rod 5331 and its second pressing and straightening connection point 53332 connected to the pressing and straightening connecting rod follower 5333 and the second pressing and straightening floating shaft 533b around the second pressing and straightening fixed shaft. The fixed shaft 5338 rotates counterclockwise to the left, causing the third pressing connection point 53333 of the pressing linkage follower 5333 to rotate counterclockwise to the left around the second pressing fixed shaft 5338, causing the pressing slide plate 5334 to move to the upper left with the anode plate pressure palm 534A to leave the left side of the stacking platform 510, and causing the pressing rotary plate 5336 to rotate clockwise around the third pressing fixed shaft 5339, causing the anode plate pressure palm 534A to leave the left side of the stacking platform 510; until the third pressing connection point 53333 comes to the line connecting the second pressing fixed shaft 5338 and the third pressing fixed shaft 5339, the pressing slide plate 5334 with the anode plate pressure palm 534A goes to the leftmost and uppermost position;

[0140] Please continue reading Figure 4 Looking from the front panel 512 of the platform, the first pressing and fixing shaft 5337 of the left anode pressing and fixing transmission assembly 533 continues to rotate clockwise to the left under the drive of the second pressing and fixing gear 3326. This drives the third pressing and fixing connection point 53333 of the pressing and fixing linkage follower 5333 to rotate counterclockwise to the left around the second pressing and fixing shaft 5338. This causes the pressing and fixing slide plate 5334 to move to the lower right with the anode pressing palm 534A and drive the pressing and fixing rotary plate 5336 to continue to rotate clockwise around the third pressing and fixing shaft 5339. This continues until the pressing and fixing slide plate 5334 becomes vertical and the anode pressing palm 534A is on the top surface of the stacking platform 510, pressing the left side of the anode in the stacking area 515.

[0141] At the same time, the right anode pressing and straightening transmission assembly 533 moves together with the left anode pressing and straightening transmission assembly 533, only the direction of movement is reversed and the left and right are opposite, while the up and down are still consistent. The first pressing and straightening fixed shaft 5337 of the right anode pressing and straightening transmission assembly 533 rotates counterclockwise under the drive of the third pressing and straightening gear 3327, and so on, until the right anode pressing palm 534A is on the top surface of the stacking platform 510 and presses the right side of the anode on the stacking area 515.

[0142] The anode plate depressurization process is as follows:

[0143] The direction of movement is completely opposite to that of the anode sheet pressing process, so I will not go into details.

[0144] The pressing and unpressing postures of the anode sheet are always in a continuous cycle, and the pressing and unpressing of the anode sheet alternate to form a continuous stacking operation.

[0145] The above-mentioned pressing and straightening linkage drive 5332 rotates below the first pressing and straightening floating shaft 533a and below the first pressing and straightening fixed shaft 5337. It can also be changed to rotate above the first pressing and straightening fixed shaft 5337. The same function is performed for the cell stacking device 500, only the direction of the anode sheet pressing and straightening drive 531 needs to be reversed. The anode sheet pressing and straightening drive 531 can also rotate continuously in one direction to alternately and continuously perform anode sheet pressing and depressurization.

[0146] The pressing and depressurization process of the cathode sheet is exactly the same as that of the anode sheet, except that the timing of the pressing and depressurization is completely different from that of the anode sheet.

[0147] The drive device configuration of this invention enables multiple motion mechanisms, such as picking up and placing anode sheets, picking up and placing cathode sheets, and stacking diaphragms, to use the same power source. This solves the problem that it is difficult to achieve consistent motion when using multiple power sources, and that disorder may even occur, affecting the quality of stacking.

[0148] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
