[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / installations can use accessories such as screws and bolts, or can be directly connected by welding, bonding, etc. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Example 1, referring to Figure 1This utility model provides a magnetic levitation stacking device, including an electrode unwinding module, a die-cutting module, an electrode conveying module, a diaphragm unwinding module 300, a magnetic levitation module, a stacking table module 400, and a stacking unloading module 500. The electrode unwinding module includes a first electrode unwinding mechanism 101, a first electrode unwinding correction mechanism 110, a second electrode unwinding mechanism 201, and a second electrode unwinding correction mechanism 211. The die-cutting module includes a first electrode die-cutting mechanism 106 and a second electrode die-cutting mechanism 206. The first electrode unwinding mechanism 101 is used for unwinding. The first electrode strip is unwound and corrected by the first electrode unwinding mechanism 110 to ensure consistent electrode entry position. The first electrode die-cutting mechanism 106 cuts the first electrode strip into a first electrode. The second electrode unwinding mechanism 201 unwinds the second electrode strip. The second electrode unwinding and correcting mechanism 211 unwinds and corrects the second electrode strip unwound by the second electrode unwinding mechanism 201. The second electrode die-cutting mechanism 206 cuts the second electrode strip into a second electrode. The electrode conveying module conveys the first electrode and the second electrode to the magnetic levitation module. At the same time, the diaphragm unwinding module 300 is used to unwind the diaphragm and convey it to the magnetic levitation module. The magnetic levitation module acquires the first electrode, the second electrode, and the diaphragm, and forms an electrode stack of first electrode-film-second electrode. The magnetic levitation module conveys the electrode stack to the stacking stage module 400 for stacking. After stacking, the stacking unloading module 500 unloads the electrode.

[0029] Specifically, both the first electrode die-cutting mechanism 106 and the second electrode die-cutting mechanism 206 include: an electrode cutting mechanism, a radius-angle die-cutting mechanism, and a dust removal and screening mechanism. The electrode strips received from the first / second electrode buffer mechanism 205 are cut to the electrode size by the electrode cutting mechanism and then by the radius-angle die-cutting mechanism. The dust removal and screening mechanism removes dust from the cut first / second electrodes, performs defect detection, rejects NG (non-compliant) first / second electrodes, and transfers OK first / second electrodes to the first / second electrode conveying module for flip-type transfer. The second electrode die-cutting module also includes a second electrode transfer mechanism 210, which transports OK second electrodes to the second electrode transfer mechanism 210, and then transfers them to the second flipping mechanism 207 for flip-type transfer.

[0030] Specifically, the stacking stage module 400 includes a stacking stage, a stacking stage lifting mechanism, and a stacking clamp disposed on the stacking stage. The stacking stage lifting mechanism is used to drive the stacking stage to rise and fall. The actions of the stacking clamp, the lifting and falling of the stacking stage, and the actions of the magnetic levitation clamp that holds the electrode stacks work together to stack the electrode stacks on the stacking stage.

[0031] In this embodiment, the magnetic levitation module includes a magnetic levitation clamp that runs along its circular magnetic levitation trajectory. The magnetic levitation clamp acquires and clamps the diaphragm at a first preset position, and acquires and clamps the first electrode and the second electrode at a second preset position. The diaphragm is located between the first electrode and the second electrode, thereby forming an electrode stack.

[0032] It is understandable that when the first electrode is the positive electrode, the second electrode is the negative electrode, and when the first electrode is the negative electrode, the second electrode is the positive electrode.

[0033] Specifically, the magnetic levitation module includes a first magnetic levitation platform 108 and a second magnetic levitation platform 208 with identical structures. The first magnetic levitation platform 108 and the second magnetic levitation platform 208 have a circular magnetic levitation trajectory. The first magnetic levitation platform 108 and the second magnetic levitation platform 208 are arranged symmetrically front to back. The first magnetic levitation platform 108 is provided with a plurality of first magnetic levitation clips 109, and the second magnetic levitation platform 208 is provided with a plurality of second magnetic levitation clips 209. It can be understood that multiple first magnetic levitation clips 109 and multiple second magnetic levitation clips 209 form corresponding sets of magnetic levitation clips. In one set of magnetic levitation clips, the first magnetic levitation clip 109 and the second magnetic levitation clip 209 extend and clamp and fix the two sides of the diaphragm at the first preset position, and then move with the magnetic levitation trajectory to drive the diaphragm to move. When the set of magnetic levitation clips moves to the second preset position, the electrode conveying module simultaneously conveys the first electrode and the second electrode to the second preset position. At this time, the first magnetic levitation clip 109 and the second magnetic levitation clip 209 open and then clamp and fix the first electrode and the second electrode, thereby obtaining an electrode stack of first electrode-film-second electrode.

[0034] In this embodiment, the electrode conveying module includes a first flipping mechanism 107 and a second flipping mechanism 207 with the same structure. The first flipping mechanism 107 and the second flipping mechanism 207 are arranged symmetrically from top to bottom and are located between the first magnetic levitation platform 108 and the second magnetic levitation platform 208. The first flipping mechanism 107 is provided with a plurality of first electrode picking robots, and the second flipping mechanism 207 is provided with a plurality of second electrode picking robots.

[0035] It can be understood that the rotational trajectories of the first electrode picking robot and the first flipping mechanism 107 move cyclically. After the first electrode picking robot picks up the first electrode at the first electrode picking position (the output position of the first electrode die-cutting mechanism 106), it moves to the second preset position along the rotational trajectory of the first flipping mechanism 107. At the same time, the second electrode picking robot and the second flipping mechanism move cyclically along their rotational trajectories. After the second electrode picking robot picks up the second electrode at the second electrode picking position (the output position of the second electrode die-cutting mechanism 206), it moves to the second preset position along the rotational trajectory of the second flipping mechanism. At this time, the diaphragm is located between the first electrode and the second electrode, which facilitates the magnetic levitation clamp to hold and fix the stack of the first electrode-diaphragm-second electrode.

[0036] The moving speeds of the first and second electrode picking robots are adapted to the conveying speed of the diaphragm. That is, the time it takes for the two first electrode picking robots to convey the first electrode to the second preset position is equal to the time it takes for the two magnetic levitation clamps to move from the first preset position to the second preset position. Similarly, the time it takes for the two second electrode picking robots to convey the second electrode to the second preset position is equal to the time it takes for the two magnetic levitation clamps to move from the first preset position to the second preset position. This ensures the formation of multiple electrode stacks and guarantees the consistency of the electrode stack quality.

[0037] Preferably, both the first and second film-retrieving robotic arms are suction cup type robotic arms. When the first and second film-retrieving robotic arms pick up the first or second electrode, the right side of the first and second electrode extends out of the first and second film-retrieving robotic arms, thereby facilitating the clamping and fixing of the first magnetic levitation clamp 109 and the second magnetic levitation clamp 209.

[0038] In this embodiment, the magnetic levitation stacking device further includes an electrode dust removal module, an electrode tension module, an automatic electrode connection module, and an electrode buffer module. The electrode dust removal module includes a first electrode dust removal mechanism 104 and a second electrode dust removal mechanism 204. The electrode tension module includes a first electrode tension mechanism 103 and a second electrode tension mechanism 203. The automatic electrode connection module includes a first automatic electrode connection mechanism 102 and a second automatic electrode connection mechanism. The electrode buffer module includes a first electrode buffer mechanism 105 and a second electrode buffer mechanism 205.

[0039] The first electrode automatic splicing mechanism 102 splices and presses the first electrode strip after unwinding and correction, then transmits it to the first electrode dust removal mechanism 104 for online dust removal. The first electrode tension mechanism 103 controls the tension of the dust-removed first electrode strip to maintain its tension and stabilize tension fluctuations during operation, and then transmits it to the first electrode buffer mechanism 105 for buffering. Similarly, the second electrode automatic splicing mechanism 202 splices and presses the second electrode strip after unwinding and correction, then transmits it to the second electrode dust removal mechanism 204 for online dust removal. The second electrode tension mechanism 203 controls the tension of the dust-removed second electrode strip to maintain its tension and stabilize tension fluctuations during operation, and then transmits it to the second electrode buffer mechanism 205 for buffering.

[0040] Example 2 differs from Example 1 in that the electrode conveying module includes a third magnetic levitation platform and a fourth magnetic levitation platform with identical structures. The third and fourth magnetic levitation platforms are arranged symmetrically vertically and are located between the first magnetic levitation platform 108 and the second magnetic levitation platform 208. The third magnetic levitation platform includes multiple third magnetic levitation manipulators along its annular magnetic levitation trajectory, and the fourth magnetic levitation platform includes multiple fourth magnetic levitation manipulators along its annular magnetic levitation trajectory.

[0041] It can be understood that the rotational trajectories of the first magnetic levitation manipulator and the third magnetic levitation platform move cyclically. After the first magnetic levitation manipulator picks up the first pole piece at the first pole piece picking position (the output position of the first pole piece die-cutting mechanism 106), it moves to the second preset position along the rotational trajectory of the third magnetic levitation platform. At the same time, the rotational trajectories of the second magnetic levitation manipulator and the fourth magnetic levitation platform move cyclically. After the second magnetic levitation manipulator picks up the second pole piece at the second pole piece picking position (the output position of the second pole piece die-cutting mechanism 206), it moves to the second preset position along the rotational trajectory of the fourth magnetic levitation platform. At this time, the diaphragm is located between the first pole piece and the second pole piece, which facilitates the magnetic levitation clamp to hold and fix the stack of the first pole piece-diaphragm-second pole piece.

[0042] Example 3, referring to Figure 2This utility model provides a magnetic levitation stacking device, including an electrode unwinding module, a die-cutting module, an electrode conveying module, a diaphragm unwinding module 300, a magnetic levitation module, a stacking table module 400, and a stacking unloading module 500. The electrode unwinding module includes a first electrode unwinding mechanism 101, a first electrode unwinding correction mechanism 110, a second electrode unwinding mechanism 201, and a second electrode unwinding correction mechanism 211. The first electrode unwinding mechanism 101 is used to unwind a first electrode strip. The first electrode unwinding correction mechanism 110 corrects the unwinding of the first electrode strip unwound by the first electrode unwinding mechanism 101 to ensure consistent electrode entry positions. The second electrode unwinding mechanism 201 is used to unwind a second electrode strip. The second electrode unwinding correction mechanism 211 corrects the unwinding of the second electrode strip unwound by the second electrode unwinding mechanism 201.

[0043] The difference between Embodiment 3 and Embodiments 1 and 2 is that the die-cutting module includes a first linear motor tracking and cutting mechanism and a second linear motor tracking and cutting mechanism, and the electrode conveying module includes a first linear motor conveying mechanism and a second linear motor conveying mechanism. The first linear motor conveying mechanism is connected to the first linear motor tracking and cutting mechanism to form a first electrode cutting and conveying mechanism 112. The first linear motor conveying mechanism is used for tilting and conveying the first electrode. The second linear motor conveying mechanism is connected to the second linear motor tracking and cutting mechanism to form a second electrode cutting and conveying mechanism 213, and the first linear motor conveying mechanism is used for tilting and conveying the second electrode. With this configuration, compared to Embodiments 1 and 2, the equipment occupies less space, better meeting the customer's need for smaller equipment size, further shortening the process flow, achieving higher precision, and improving production efficiency.

[0044] Furthermore, the magnetic levitation stacking equipment also includes an electrode dust removal module, an electrode tension module, an automatic electrode splicing module, and an electrode travel correction mechanism module. The electrode dust removal module includes a first electrode dust removal mechanism 104 and a second electrode dust removal mechanism 204. The electrode tension module includes a first electrode tension mechanism 103 and a second electrode tension mechanism 203. The automatic electrode splicing module includes a first automatic electrode splicing mechanism 102 and a second automatic electrode splicing mechanism. The electrode travel correction mechanism module includes a first electrode travel correction mechanism 111 and a second electrode travel correction mechanism 212. The first electrode travel correction mechanism 111 is used for correction of the first electrode strip before die cutting, and the second electrode travel correction mechanism 212 is used for correction of the second electrode strip before die cutting.

[0045] In embodiments 1-3 of this utility model, each mechanism adopts the prior art. The innovation of this utility model lies in the combination and layout of the mechanisms. Therefore, the specific structure and operating principle of each mechanism will not be described in detail.
