[0041] The following will clearly and completely describe the technical solutions of the embodiments of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection requested by this application.

[0043] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0044] See also Figure 1 and Figure 2 The first aspect provided in the embodiments of the present application provides a rotary clamping assembly, including: a pressure plate 1, a support block 2 and a toggle member 3.

[0045] The pressing plate 1 can be flipped and set on the support block 2. In this embodiment, the top surface of the support block 2 can be used to place materials. Optionally, the material is in sheet form, such as a pole piece, so that the pressing plate 1 can press the material tightly. In the following, for ease of explanation, the material is taken as an example of a pole piece. Optionally, the top surface of the support block 2 is a plane. When the pressing plate 1 is flipped to press the support block 2, the pressing plate 1 abuts the top surface of the support block 2 or the pole piece on the top surface of the support block 2.

[0046] When the pressing plate 1 is flipped open relative to the support block 2, the electrode can be placed on the support block 2. After the pressing plate 1 is flipped to fit the electrode on the support block 2, the electrode can be pressed tightly against the support block 2. After that, the movement of the support block 2 can drive the electrode to move synchronously to realize the transmission of the electrode.

[0047] The toggle member 3 is disposed outside the support block 2 and is fixedly connected to the pressure plate 1 ; the toggle member 3 is used to drive the pressure plate 1 toward or away from the support block 2 when being toggled.

[0048] In this embodiment, the toggle member 3 serves as a flip control member for the pressure plate 1 . Its arrangement outside the support block 2 facilitates the transmission structure to contact the toggle member 3 , which helps to simplify the overall structure.

[0049] As an embodiment, the transmission structure drives the toggle member 3 to rotate by, for example, driving the toggle rod to rotate via a motor, and then the toggle rod contacts the toggle member 3 to cause the toggle member 3 to flip.

[0050] Compared with the method of fixing the pole piece with a clamp, the device in this solution does not need to be provided with a matching structure such as a guide rail for sliding the clamp, which can simplify the equipment.

[0051] In one embodiment, the pressing plate 1 is a strip-shaped plate. Specifically, the pressing plate 1 includes a long side and a short side. The long side is longer than the short side. The long side of the pressing plate 1 can be flipped to connect to the support block 2. This allows the pressing plate 1 to adapt to different sizes of pole pieces, ensuring that the pole pieces can be compressed even when the size changes.

[0052] In practical applications, after the electrodes are stacked, they are in a stacked state. The pressing plate 1 provided in the above embodiment can also compress the laminated electrodes, allowing the support block 2 to transport the laminated electrodes. Therefore, the rotary clamping assembly provided in the embodiment of the present application can also be used for lamination pre-processing in the lamination process, so that the electrodes are stacked on the support block 2 and compressed by the pressing plate 1 during transportation.

[0053] Furthermore, the method of using the pressing plate 1 to press the electrode in this embodiment is less likely to damage the coating on the electrode surface than the method of using the clamp to open the clamp.

[0054] In one embodiment, see Figure 3 The rotary clamping assembly also includes: a rotating shaft 4; the rotating shaft 4 is rotatably arranged on the support block 2; the pressure plate 1 is fixedly connected to the rotating shaft 4; one end of the rotating shaft 4 extends out of the support block 2 and is fixedly connected to the toggle member 3.

[0055] In this embodiment, the rotating shaft 4 serves as a turning shaft of the pressing plate 1. In addition, the shifting member 3 is disposed outside the supporting block 2 via the rotating shaft 4.

[0056] In another embodiment provided in this application, please refer to Figures 1 to 4 The rotating clamping assembly also includes: an elastic member 5; the elastic member 5 connects the support block 2 and the pressure plate 1.

[0057] In applications, such as Figure 3 As shown, when an upward driving force acts on the toggle member 3, the toggle member 3 flips upward and drives the pressure plate 1 to move away from the support block 2. At this time, the elastic member 5 is gradually compressed and enters a state of energy storage, providing elastic force for the pressure plate 1 to move toward the support block 2. When the driving force of the toggle member 3 is removed, the elastic force of the elastic member 5 drives the pressure plate 1 to flip toward the support block 2 until the pressure plate 1 presses against the electrode. Therefore, during transportation, when the toggle member 3 is not toggled, the pressure plate 1 is in a state of pressing against the electrode.

[0058] It should be noted that, without the elastic member 5, the pressure plate 1 can be driven by gravity to press the support block 2; correspondingly, a counterweight can be provided on the pressure plate 1 to specifically provide the pressure plate 1 with a downward pressing tendency. In this embodiment, the provision of the elastic member 5 ensures the downward pressing tendency of the pressure plate 1, thereby ensuring the compression effect on the electrode.

[0059] Optionally, a mounting tube 8 may be provided on the support block 2. The elastic member 5 may be a spring column and is provided in the mounting tube 8.

[0060] Optionally, the elastic member 5 includes a plurality of elastic members 5, which are distributed in a straight line and at intervals. Correspondingly, a plurality of mounting tubes 8 are provided.

[0061] In other embodiments provided in this application, please refer to Figure 5 The rotary declamping assembly further comprises a push plate 6. The push plate 6 is configured so that the toggle member 3 can contact the push plate 6 during the transport of the support block 2. When the support block 2 moves past the push plate 6, the push plate 6 pushes the toggle member 3 to rotate, causing the pressure plate 1 to flip away from the support block 2.

[0062] Specifically, when the support block 2 moves to contact the push plate 6, as the support block 2 moves, the push plate 6 gradually pushes the toggle member 3 to rotate upward, thereby driving the pressure plate 1 to rotate upward and loosening the clamping state of the pressure plate 1. At this time, the electrode piece can be placed on the support block 2 or removed from the support block 2. Correspondingly, after the toggle member 3 leaves the push plate 6, the pressure plate 1 is reset to the clamping state by the elastic force of the elastic member 5, or the pressure plate 1 is reset to the clamping state by gravity.

[0063] In actual application, it is only necessary to set the push plate 6 in the conveying direction of the support block 2, so that the pressure plate 1 can be automatically opened and closed as the support block 2 is conveyed, meeting the rapid transportation requirements of the electrode.

[0064] In a more specific embodiment, an end of the push plate 6 facing the moving direction of the support block 2 is provided with an arc-shaped surface that is inclined upward and convex; and a side of the toggle member 3 used to abut against the push plate 6 is provided with an arc-shaped surface that is inclined downward and convex.

[0065] Specifically, see Figure 5 , the direction in which the support block 2 moves to transport the material is Figure 5 The positive direction of the X-axis in FIG is the positive direction of the X-axis, and the end of the push plate 6 moving toward the support block 2 is the end of the push plate 6 along the negative direction of the X-axis. When the support block 2 is conveyed until the toggle member 3 abuts the push plate 6, the curved surface of the toggle member 3 contacts the curved surface of the push plate 6. As the support block 2 is conveyed, the contact position of the toggle member 3 and the push plate 6 gradually changes, causing the toggle member 3 to gradually rotate upward.

[0066] It should be noted that, in this embodiment, by providing curved surfaces on the push plate 6 and the toggle member 3, the push plate 6 and the toggle member 3 can be prevented from getting stuck when in contact, thereby ensuring smooth electrode conveyance.

[0067] In another embodiment, see Figure 6 The rotary clamping assembly also includes: a lifting cylinder 7; the output end of the lifting cylinder 7 is connected to the push plate 6.

[0068] The height of the push plate 6 can be adjusted by the lifting cylinder 7. Specifically, in actual application, the lifting cylinder 7 needs to be installed on the side of the support block 2 in the transportation direction according to the site requirements; then the position of the push plate 6 can be adjusted by the lifting cylinder 7 to ensure that it can drive the toggle member 3 to rotate.

[0069] See also Figures 1 to 7 In a second aspect, the present application provides a conveying device comprising: a conveyor belt 10 and a plurality of any one of the above-mentioned rotating clamping assemblies; the support block 2 in the rotating clamping assembly is fixed on the conveyor belt 10.

[0070] Specifically, the support block 2 can be fixed on the connecting block 9. The connecting block 9 is fixed on the conveyor belt 10. The conveyor belt 10 is an endless conveyor belt that can realize continuous conveyance of the support block 2.

[0071] In the embodiment in which the push plate 6 is provided, the push plate 6 is provided beside the conveyor belt 10. Taking the conveyor belt 10 as an example in which the conveyor belt 10 can be transportably provided on the device body, the push plate 6 or the lifting cylinder 7 can be fixedly provided on the device body.

[0072] In one embodiment, the push plates 6 include at least two; at least two push plates 6 are respectively disposed at both ends of the conveyor belt 10 .

[0073] The area where one push plate 6 is located is used as the electrode loading area, and the area where the other push plate 6 is located is used as the electrode unloading area.

[0074] Specifically, the push plate 6 can be a strip-shaped plate. From the moment the toggle member 3 passes through the curved surface of the push plate 6 until the toggle member 3 leaves the push plate 6, the pressure plate 1 is in the open state, thereby enabling the loading and unloading of the electrode. In practical applications, the push plate 6 can be a spliced ​​or retractable structure so that the length of the push plate 6 can match the loading and unloading rate of the electrode.

[0075] As an embodiment, the conveyor belt 10 is a magnetic levitation conveyor belt, which has higher transportation efficiency and transportation stability.

[0076] The above are only preferred embodiments of the present application and are not intended to limit the present invention.
