Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to handling mechanisms, electrode stacking devices, and battery manufacturing systems. Background Technology

[0002] With the rapid development of the lithium battery industry, the production efficiency requirements for power batteries are becoming increasingly stringent. During the electrode stacking process, a handling mechanism is typically used to move the electrodes to the next stage of the process. However, the traditional handling mechanism's structural design limits its handling efficiency, thus affecting the electrode stacking efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a handling mechanism, an electrode stacking device, and a battery production system to accelerate handling efficiency and improve production efficiency.

[0004] In a first aspect, this application provides a handling mechanism, comprising: a picking component for picking up a workpiece to be processed on a first station and releasing the workpiece to be processed on a second station, the picking component comprising at least two components; and a switching component for driving each picking component to switch sequentially between the first station and the second station; wherein the switching component is further configured to simultaneously drive at least one picking component to switch to the second station when driving at least one picking component to switch to the first station.

[0005] The aforementioned conveying mechanism is equipped with at least two picking components. During the conveying process, when at least one picking component is driven to switch to the first station by switching components, at least one picking component will simultaneously switch to the second station. This allows at least two picking components to simultaneously complete the picking action at the first station and the releasing action at the second station, realizing parallel picking and releasing actions, accelerating conveying efficiency, and improving production efficiency.

[0006] In some embodiments, the conveying mechanism further includes a moving component for driving the pickup component to move closer to or away from the first or second workstation. This design, by introducing the moving component, allows the pickup component to be closer to the first or second workstation, making the pickup or release of the workpiece more stable and improving the stability of pick-up and placement. Simultaneously, the moving component can also raise the pickup component, facilitating reliable switching of the pickup component and reducing the probability of structural interference during switching.

[0007] In some embodiments, the handling mechanism further includes a mounting base disposed on a switching component. The switching component drives the mounting base to rotate about its own axis. Each pickup component is disposed on the mounting base and spaced apart around the axis of the mounting base. Each pickup component can move along the axis of the mounting base under the action of the moving component. This design, which switches the position of the pickup components by rotation, allows each pickup component to cyclically switch between the first and second workstations in the same direction, further improving handling efficiency.

[0008] In some embodiments, the handling mechanism further includes at least two guide rails and at least two slides. The guide rails are spaced apart around the axis of the mounting base and extend along the axial direction of the mounting base. Each pickup component is slidably mounted on the corresponding guide rail via the slide. This design, through the cooperation of the slide and the guide rail, allows each pickup component to smoothly approach the first or second workstation, which helps to improve the smoothness of handling.

[0009] In some embodiments, the conveying mechanism further includes a connecting seat, through which each pickup component is connected to a corresponding slide. The connecting seat includes a first connecting portion, a second connecting portion, and a reinforcing portion. The first connecting portion and the second connecting portion are connected at an angle, and the reinforcing portion is connected between the first and second connecting portions. The pickup component is connected to the first connecting portion, and the second connecting portion is connected to the slide. This design facilitates strengthening the mounting structure of the pickup component on the slide, improving structural stability. Simultaneously, the connecting seat allows the pickup component to extend from the mounting seat, enabling it to better contact the first or second workstation, thus facilitating pick-up and drop-off operations.

[0010] In some embodiments, the switching assembly includes a first motor and a reducer connected to the first motor, with a mounting base disposed at the output end of the reducer. This design, by introducing the reducer, facilitates the first motor to output greater torque, resulting in more stable rotation of each pickup assembly and improved handling stability.

[0011] In some embodiments, the moving components include at least two, each moving component being used to drive the corresponding picking component to move. This design allows the movement of the picking components to be independently driven, facilitating the adjustment of the height of the picking components according to the pick-up and placement height, making the picking and placing of the items to be processed more stable and reliable.

[0012] In some embodiments, the conveying mechanism further includes a second motor for driving the pickup components to rotate about their respective axes. This design, by introducing the second motor, allows for changing the orientation of the workpiece on the pickup components, ensuring that the placement angle of the workpiece at the second station meets requirements, thus achieving initial adjustment or correction.

[0013] In some embodiments, the second motor includes at least two components, each of which drives a corresponding pickup component to rotate. This design allows each pickup component to rotate independently according to its corresponding second motor, facilitating the fulfillment of different placement requirements for the parts to be processed at the second workstation and improving adjustment flexibility.

[0014] In some embodiments, the pickup assembly includes a suction element for communication with a vacuum device to adsorb the workpiece. This design facilitates effective vacuum adsorption of the workpiece, thereby enabling efficient and stable pickup.

[0015] Secondly, this application provides an electrode stacking device, which includes a conveying mechanism as described in any of the above claims. The electrode stacking device has a first station and a second station, and the conveying mechanism is used to transfer the workpiece to be processed from the first station to the second station. This design allows at least two picking components to simultaneously complete the picking action at the first station and the releasing action at the second station, realizing parallel picking and placing actions, accelerating the conveying efficiency, and improving production efficiency.

[0016] In some embodiments, the electrode stacking apparatus further includes: a conveying mechanism for conveying the workpiece to be processed to a first station; a correction mechanism having a second station for correcting the deviation of the workpiece located at the second station; and a stacking platform for stacking the corrected workpiece. This design facilitates stable stacking processes and improves stacking efficiency.

[0017] Thirdly, this application provides a battery production system, which includes the above-mentioned electrode stacking device. Attached Figure Description

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] Currently, judging from market trends, the application of power battery devices is becoming increasingly widespread. Power battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields. With the continuous expansion of the application areas of power battery devices, the market demand is also constantly increasing.

[0032] To meet the rapid expansion demands of power batteries, a transport mechanism is typically used during the electrode stacking process to move the electrodes to the next stage. For example, during transport, a robotic arm picks up the electrodes from the conveyor belt; after picking, it rotates the arm above a alignment mechanism and places the electrode on the alignment mechanism; after release, it rotates back above the conveyor belt, and this cycle repeats. However, this method offers relatively limited improvement in transport efficiency and cannot meet the demands of higher-efficiency electrode stacking production.

[0033] Based on this, and addressing the limited improvement in handling efficiency offered by traditional handling mechanisms, this application provides a handling mechanism in which at least two picking components are provided. During the handling process, by switching components, when at least one picking component is driven to switch to the first station, at least one picking component will simultaneously switch to the second station. This allows at least two picking components to simultaneously complete the picking action at the first station and the releasing action at the second station, achieving parallel picking and releasing actions, accelerating handling efficiency, and improving production efficiency.

[0034] According to some embodiments of this application, please refer to Figure 1 and Figure 2 This application provides a handling mechanism, which includes a switching component 20 and at least two picking components 10. The picking components 10 are used to pick up the workpiece 60 to be processed on a first station 73 and release the workpiece 60 to be processed on a second station 74; the switching component 20 is used to drive the picking components 10 to switch sequentially between the first station 73 and the second station 74; wherein, the switching component 20 is further configured to simultaneously drive at least one picking component 10 to switch to the second station 74 when driving at least one picking component 10 to switch to the first station 73.

[0035] The pickup component 10 refers to a component with pickup and release functions. Its pickup method can be, but is not limited to, vacuum adsorption, gripping, magnetic adsorption, etc. Specifically, in some examples, the pickup component 10 uses vacuum adsorption. For example, the pickup component 10 located above the first station 73 can pick up the workpiece 60 to be processed by vacuum adsorption, and the pickup component 10 located above the second station 74 can break the vacuum and release the adsorbed workpiece 60.

[0036] The switching component 20 refers to the device that provides power for the pickup component 10 to switch between the first station 73 and the second station 74. The switching method can be, but is not limited to, rotary switching or linear movement switching. When the switching method of the switching component 20 is rotary switching, the switching component 20 can be a motor or a combination of a motor and a transmission mechanism, such as a combination of a motor and a gear set, or a combination of a motor and a roller belt; in this case, the pickup component 10 can rotate between the first station 73 and the second station 74. When the switching method of the switching component 20 is linear movement switching, the switching component 20 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric cylinder, or a linear module.

[0037] When there are at least two pickup components 10, under the action of the switching component 20, the at least two pickup components 10 alternately switch between the first station 73 and the second station 74, so that the picking and placing actions of the workpiece 60 to be processed are parallel, so as to complete the picking and releasing actions synchronously in one transport. For example, under the action of the switching component 20, the unloaded pickup component 10 switches to the first station 73, and the pickup component 10 picking up the workpiece 60 to be processed switches to the second station 74 simultaneously.

[0038] For ease of understanding, let's take two pickup components 10 as an example. If the switching method is rotational switching, the two pickup components 10 can be symmetrically distributed about the rotation axis. This way, after rotating 180°, the two pickup components 10 will always be positioned above the first station 73 and the second station 74, respectively. If the switching method is movement switching, the first station 73 can be set on opposite sides of the second station 74. See the attached document for details. Figure 3 Alternatively, second stations 74 may be set on opposite sides of the first station 73, so that the two picking components 10 can linearly switch between the two second stations 74 and the first station 73; or between the two first stations 73 and the second stations 74.

[0039] When picking up more than three components of component 10, please refer to... Figure 4 The picking components 10 can be distributed at intervals along the circumference, and the first station 73 and the second station 74 are also distributed alternately along the circumference, so that there is a picking component 10 above the first station 73 and the second station 74 after each rotation, and the picking components 10 alternate between the first station 73 and the second station 74. It can be seen that, regardless of whether the number of picking components 10 is odd or even, the number of stations distributed in the circle should be as even as possible, so that two adjacent stations will not both be the first station 73 or the second station 74, so that the picking and placing actions are performed alternately.

[0040] Of course, if the switching component 20 is a moving switching, every two picking components 10 can be used as a picking group and each picking group can be set in parallel; at the same time, the first station 73, the second station 74 and the first station 73 can be used as a station group and each station group can be set in parallel.

[0041] Furthermore, it should be noted that the first station 73 and the second station 74 refer to the positions where the picking component 10 picks up and releases the workpiece 60 to be processed, respectively. When the workpiece 60 to be processed reaches the first station 73, one of the picking components 10 picks up the workpiece 60 from the first station 73; simultaneously, the other picking component 10 releases the workpiece 60 to be processed from the second station 74. Then, under the action of the switching component 20, the unloaded picking component 10 switches to the first station 73, and the picking component 10 picking up the workpiece 60 switches to the second station 74. It is easy to understand that the handling mechanism of this embodiment is not limited to the electrode stacking process, but can be applied to other processes that require handling operations. When the handling mechanism is applied in the electrode stacking process, the workpiece 60 to be processed can be an electrode.

[0042] This design allows at least two picking components 10 to simultaneously complete the picking action at the first station 73 and the releasing action at the second station 74, achieving parallel picking and releasing actions, accelerating handling efficiency, and improving production efficiency.

[0043] Optionally, according to some embodiments of this application, please refer to Figure 2 The handling mechanism also includes a moving component 80, which is used to drive the picking component 10 toward or away from the first station 73 or the second station 74.

[0044] When the picking component 10 switches to the first station 73 or the second station 74, the moving component 80 can drive the picking component 10 to move closer to the first station 73 or the second station 74, so that the picking component 10 can better pick up or release the workpiece 60 to be processed; after picking up or placing, the moving component 80 can drive the picking component 10 away from the first station 73 or the second station 74, raise the picking component 10, so that the switching component 20 can switch each picking component 10, reducing the probability of structural interference during the switching process.

[0045] The number of moving components 80 can be one or more. When there is one moving component 80, the same moving component 80 can drive each picking component 10 to move synchronously, so as to synchronously move towards or away from the first station 73 or the second station 74. When there are multiple moving components 80, each picking component 10 can be driven by its corresponding moving component 80 individually. The structure of the moving component 80 can have various designs, such as, but not limited to, cylinders, hydraulic cylinders, electric cylinders, linear modules, etc., or it can be a motor and transmission mechanism, such as, a combination of a motor and a gear and rack, a combination of a motor and a lead screw mechanism, etc. To achieve control of the movement stroke, limit switches can also be set on the mounting base 30, such as, but not limited to, limit switches, micro switches, and other contact switches, or photoelectric switches, proximity switches, etc.

[0046] In addition, there are various installation relationships between the moving component 80 and the switching component 20. For example, the moving component 80 is located at the output end of the switching component 20, and the pickup component 10 is located at the output end of the moving component 80. In this way, during the switching process, the switching component 20 drives the moving component 80 and the pickup component 10 to switch together. Alternatively, the switching component 20 is located at the output end of the moving component 80, and the pickup component 10 is located at the output end of the switching component 20. In this way, during the movement, the moving component 80 drives the switching component 20 and the pickup component 10 to move together.

[0047] This design, by introducing the moving component 80, allows the picking component 10 to be closer to the first station 73 or the second station 74, making the picking or releasing of the workpiece 60 more stable and improving the stability of picking and placing. At the same time, the moving component 80 can also be used to raise the picking component 10, making it easier to switch the picking component 10 reliably and reducing the probability of structural interference during the switching process.

[0048] Optionally, according to some embodiments of this application, please refer to Figure 2 The conveying mechanism also includes a mounting base 30, which is located on the switching component 20. The switching component 20 is used to drive the mounting base 30 to rotate around its own axis. Each pickup component 10 is located on the mounting base 30 and is distributed at intervals around the axis of the mounting base 30. Each pickup component 10 can move along the axis of the mounting base 30 under the action of the moving component 80.

[0049] It can be seen that when switching the pickup component 10, the mounting base 30 can be driven to rotate around its own axis by the switching component 20, so that the circumferentially distributed pickup components 10 rotate around the axis of the mounting base 30, and the pickup components 10 alternately switch between the first station 73 and the second station 74 in sequence. In some specific examples, there are two pickup components 10, and the two pickup components 10 are respectively disposed on two opposite surfaces of the mounting base 30.

[0050] There are several ways in which the switching component 20 drives the mounting base 30. For example, the switching component 20 is a motor, which is connected to the mounting base 30 through a coupling; or, the switching component 20 is a combination of a motor and a gear set, which transmits the rotation of the motor to the mounting base 30 through the gear set; or, the switching component 20 is a combination of a motor and a roller belt, which transmits rotational power to the mounting base 30 through the belt.

[0051] When the unloaded pickup component 10 switches to the first station 73, and the pickup component 10 with the workpiece 60 to be processed switches to the second station 74, the moving component 80 can drive the pickup component 10 to move closer to the first station 73 and the second station 74 respectively, so that the pickup component 10 can stably adsorb the workpiece 60 to be processed on the first station 73. At the same time, the fully loaded pickup component 10 can stably release the workpiece 60 to be processed on the second station 74. There are several ways to slide the pickup component 10 on the mounting base 30. For example, the pickup component 10 can be set on the mounting base 30 through the guide rail 31; or it can be set on the mounting base 30 through components such as ball bearings.

[0052] Furthermore, the individual pickup components 10 are spaced apart around the axis of the mounting base 30, allowing each pickup component 10 to alternately switch between the first station 73 and the second station 74 during rotation. When the number of pickup components 10 is three or more, and is even, please refer to [the relevant documentation]. Figure 5 The workstations can be distributed alternately along the circumference, for example, workstation 73, workstation 74, workstation 73, workstation 74, etc., alternating sequentially. In some specific examples, the number of picking components 10 is two, and the two picking components 10 are evenly distributed around the axis of the mounting base 30.

[0053] This design allows the position of the picking components 10 to be switched by rotation, enabling each picking component 10 to cyclically switch between the first station 73 and the second station 74 in the same direction, further improving handling efficiency.

[0054] Optionally, according to some embodiments of this application, please refer to Figure 2 The conveying mechanism also includes at least two guide rails 31 and at least two slides 32. Each guide rail 31 is spaced apart around the axis of the mounting base 30 and extends along the axial direction of the mounting base 30. Each picking component 10 is slidably mounted on the corresponding guide rail 31 via the slide 32.

[0055] When each pickup component 10 switches to the corresponding station, such as when an unloaded pickup component 10 switches to the first station 73 and a fully loaded pickup component 10 switches to the second station 74, the slide 32 can cooperate with the guide rail 31 to make each pickup component 10 smoothly approach the first station 73 or the second station 74.

[0056] The guide rail 31 and the slide 32 can be configured one-to-one or many-to-one, such as the same slide 32 being set on multiple guide rails 31.

[0057] This design, through the cooperation of the slide 32 and the guide rail 31, allows each picking component 10 to smoothly approach the first station 73 or the second station 74, which helps to improve the smoothness of the handling.

[0058] Optionally, according to some embodiments of this application, please refer to Figure 6 The conveying mechanism also includes a connecting seat 40, through which each pickup component 10 is connected to the corresponding slide 32; wherein, the connecting seat 40 includes a first connecting part 41, a second connecting part 42 and a reinforcing part 43, the first connecting part 41 and the second connecting part 42 are connected at an angle, the reinforcing part 43 is connected between the first connecting part 41 and the second connecting part 42, the pickup component 10 is connected to the first connecting part 41, and the second connecting part 42 is connected to the slide 32.

[0059] In the connector 40, the first connecting part 41 and the second connecting part 42 are connected at an angle, and the reinforcing part 43 is connected between the first connecting part 41 and the second connecting part 42, thus forming a triangular structure. This facilitates the reinforcement of the mounting structure of the pickup assembly 10 on the slide 32 and improves structural stability. In some specific examples, the first connecting part 41 and the second connecting part 42 are connected perpendicularly.

[0060] The introduction of a connecting seat 40 between the pickup component 10 and the slide 32 facilitates the extension of the pickup component 10 from the mounting seat 30, enabling the pickup component 10 to better contact the first station 73 or the second station 74, thereby facilitating the pickup and placement actions.

[0061] The connection between the first connecting part 41, the second connecting part 42 and the reinforcing part 43 can be in various ways, such as, but not limited to, bolt connection, snap-fit, welding, riveting, etc. Of course, the first connecting part 41, the second connecting part 42 and the reinforcing part 43 can also be designed as an integrated structure.

[0062] This design facilitates the reinforcement of the mounting structure of the pickup component 10 on the slide 32, improving the stability of the structure. At the same time, the connecting seat 40 facilitates the extension of the pickup component 10 from the mounting seat 30, allowing the pickup component 10 to better contact the first station 73 or the second station 74, thereby facilitating the picking and placing actions.

[0063] Optionally, according to some embodiments of this application, please refer to Figure 2 The switching component 20 includes a first motor 21 and a reducer 22 connected to the first motor 21, and the mounting base 30 is located at the output end of the reducer 22.

[0064] The first motor 21 and the reducer 22 can be directly connected via a coupling. Alternatively, they can be connected via helical gears to change the direction of torque input and output. In some specific examples, the axis of the first motor 21 is perpendicular to the axis of the reducer 22.

[0065] This design, with the introduction of a speed reducer 22, allows the first motor 21 to output greater torque, making the rotation of each pickup component 10 more stable and improving the stability of the handling.

[0066] Optionally, according to some embodiments of this application, please refer to Figure 2 The moving component 80 includes at least two components, each of which is used to drive the corresponding picking component 10 to move.

[0067] Therefore, the movement of each pickup component 10 is independently driven. For example, when an unloaded pickup component 10 switches to the first station 73 and a fully loaded pickup component 10 switches to the second station 74, one of the moving components 80 drives the unloaded pickup component 10 to move closer to the first station 73, making the pickup component 10 close to the workpiece 60 to be processed on the first station 73 for easy pickup. The other moving component 80 drives the fully loaded pickup component 10 to move closer to the second station 74, allowing the pickup component 10 to release the workpiece 60 to be processed at a suitable height.

[0068] In some specific examples, each movable component 80 is mounted on the mounting base 30, and the output of each movable component 80 is connected to the corresponding slide 32.

[0069] This design allows the movement of the pickup component 10 to be independently driven, making it easy to adjust the height of the pickup component 10 according to the pickup and placement height, thus making the pickup and placement of the workpiece 60 more stable and reliable.

[0070] Optionally, according to some embodiments of this application, please refer to Figure 2 The conveying mechanism also includes a second motor 50, which drives the pickup assembly 10 to rotate about its respective axis.

[0071] The second motor 50 refers to a device that can drive the pickup assembly 10 to rotate around its own axis to change the orientation of the workpiece 60 to be processed on the pickup assembly 10. For example, after the pickup assembly 10 picks up the workpiece 60 to be processed from the first station 73, in order to ensure that the workpiece 60 to be processed meets the prescribed placement on the second station 74, the second motor 50 can drive the pickup assembly 10 to rotate, thereby changing the orientation of the workpiece 60 to achieve preliminary adjustment or correction.

[0072] The axis of the pickup component 10 can intersect with the surface of the workpiece 60 facing the pickup component 10. For example, the axis of the pickup component 10 is perpendicular to the surface of the workpiece 60 facing the pickup component 10. In this way, after the pickup component 10 is rotated, the orientation of the workpiece 60 can be changed, so that the placement angle of the workpiece 60 on the second station 74 meets the requirements.

[0073] In addition, there are various ways to drive the second motor 50 and the pickup component 10. For example, the output end of the second motor 50 can be directly connected to the pickup component 10; or a gear set, roller belt or other transmission mechanism can be set between the second motor 50 and the pickup component 10.

[0074] This design introduces a second motor 50, which can change the orientation of the workpiece 60 on the picking component 10, so that the placement angle of the workpiece 60 on the second station 74 meets the requirements, and achieves preliminary adjustment or correction.

[0075] Optionally, according to some embodiments of this application, please refer to Figure 2 The second motor 50 includes at least two, and each second motor 50 is used to drive the corresponding pickup component 10 to rotate.

[0076] It can be seen that the rotation of each pickup component 10 can be performed independently, that is, each pickup component 10 can rotate independently according to the corresponding second motor 50, which is convenient to meet the different placement requirements of the workpiece 60 to be processed on the second workstation 74. Specifically, in some examples, the output end of the switching component 20 is connected to the mounting base 30, and the mounting base 30 is provided with connecting seats 40 at intervals along its circumference. The pickup component 10 is connected to the connecting seat 40 through the second motor 50.

[0077] With this design, each picking component 10 can rotate independently according to the corresponding second motor 50, which can easily meet the different placement requirements of the parts to be processed 60 on the second workstation 74 and improve the flexibility of adjustment.

[0078] According to some embodiments of this application, optionally, the pickup component 10 includes a suction member for communicating with a vacuum device to pick up the item 60 to be processed.

[0079] A suction component is a structure that can create a negative pressure on the surface of the workpiece 60 to be processed, so that the workpiece 60 is vacuum-adsorbed. It can be plate-shaped, disc-shaped, or other structures. When the vacuum equipment suctions the suction component, the workpiece 60 on the first station 73 can be adsorbed onto the suction component to complete the pickup of the workpiece 60.

[0080] This design facilitates the effective vacuum adsorption of the workpiece 60, thereby enabling efficient and stable pickup of the workpiece 60.

[0081] According to some embodiments of this application, this application provides an electrode stacking device, which includes a transport mechanism as described in any of the above, the electrode stacking device having a first station 73 and a second station 74, and the transport mechanism being used to transfer the workpiece 60 to be processed from the first station 73 to the second station 74.

[0082] This design allows at least two picking components 10 to simultaneously complete the picking action at the first station 73 and the releasing action at the second station 74, achieving parallel picking and releasing actions, accelerating handling efficiency, and improving production efficiency.

[0083] According to some embodiments of this application, optionally, the electrode stacking apparatus further includes: a conveying mechanism 70, a correction mechanism 71, and a stacking platform 72. The conveying mechanism 70 is used to convey the workpiece 60 to be processed to a first station 73; the correction mechanism 71 has a second station 74 and is used to correct the deviation of the workpiece 60 located at the second station 74. The stacking platform 72 is used for stacking the corrected workpiece 60.

[0084] The conveying mechanism 70 refers to the equipment that can convey the workpiece 60 to the first workstation 73, such as, but not limited to, belt conveyors, roller conveyors, etc.

[0085] The correction mechanism 71 is a device that can adjust the position and orientation of the workpiece 60 to be processed. For example, when the workpiece 60 is placed on the correction mechanism 71, the correction mechanism 71 can be used to translate the workpiece 60 in different directions or rotate it around the axis so that the state of the workpiece 60 meets the required state.

[0086] During the stacking process, the corrected workpiece 60 can be transferred to the stacking table 72 for stacking via a transfer device, such as a robotic arm or a handling mechanism as described in the above embodiments.

[0087] This design facilitates stable wafer stacking processes and improves stacking efficiency.

[0088] According to some embodiments of this application, this application provides a battery production system, which includes the above-mentioned electrode stacking device.

[0089] According to some embodiments of this application, a conveying mechanism is provided, comprising a first motor 21, a reducer 22, a mounting base 30, guide rails 31, slides 32, a connecting base 40, a moving component 80, a second motor 50, and a pickup component 10. The first motor 21 is connected to the reducer 22, and the mounting base 30 is disposed at the output end of the reducer 22. Two guide rails 31 are disposed on the mounting base 30 and spaced apart around the axis of the mounting base 30. Two slides 32 are disposed on corresponding guide rails 31, and the moving component 80 is used to drive the slides 32 to move on the guide rails 31. Two second motors 50 are each disposed on corresponding slides 32 via the connecting base 40, and two pickup components 10 are respectively disposed at the output ends of the second motors 50. The pickup component 10 is a suction component used for vacuum adsorption of electrode sheets.
