Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a flipping device, a battery flipping method, and a battery manufacturing device. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automotive industry. Electric vehicles have become an important part of the sustainable development of the automotive industry due to their energy-saving and environmental protection advantages.

[0003] For electric vehicles, battery technology is an important factor in their development. How to improve battery manufacturing efficiency is a technical problem that needs to be solved urgently in battery technology. Summary of the Invention

[0004] The present application provides a flipping device, a battery flipping method and a battery manufacturing device. The technical solution provided in the present application can effectively improve the efficiency of flipping the battery, thereby improving the manufacturing efficiency of the battery.

[0005] This application is achieved through the following technical solutions:

[0006] In a first aspect, some embodiments of the present application provide a flipping device, comprising a flipping platform and a rotation mechanism. The flipping platform has a constrained space for accommodating a battery to constrain the battery's posture. The rotation mechanism is connected to the flipping platform and is used to drive the flipping platform to rotate around a rotation axis. The flipping platform is configured to switch from a first position to a second position under the drive of the rotation mechanism; when the flipping platform is in the first position, the battery enters the channel in a first posture, and when the flipping platform is in the second position, the battery flips from the first posture to the second posture and leaves the constrained space in the second posture.

[0007] In the above scheme, the process of flipping the battery using the flipping device can be broken down into three steps: the battery enters the constrained space of the flipping platform, the flipping platform rotates, and the battery leaves the constrained space. Therefore, flipping the battery using the flipping device, so that the battery switches from a first posture to a second posture, can effectively improve the battery flipping rhythm, resulting in higher flipping efficiency and thus improved battery manufacturing efficiency. Furthermore, during the flipping process, the battery switches postures as the flipping platform switches position. Since the battery is constrained in the constrained space, the risk of the battery slipping and being thrown away due to inertia is low, the flipping quality is high, and thus the battery manufacturing efficiency is high.

[0008] According to some embodiments of the present application, the confined space includes an inlet and an outlet, the inlet is for the battery to enter the confined space, and the outlet is for the battery to leave the confined space.

[0009] In the above solution, by setting the inlet and outlet, the battery is limited to enter and leave the constrained space from different parts, reducing the risk of interference between the battery and the inlet and outlet, improving the battery flipping rhythm, and thus enabling the battery to have higher manufacturing efficiency.

[0010] According to some embodiments of the present application, the inlet and the outlet are opposite to each other along the first direction.

[0011] In the above scheme, the inlet and outlet are arranged relative to each other along the first direction, so that the battery can move unidirectionally along the first direction in the constrained space, which can reduce the difficulty of the battery entering and leaving the channel. For example, by using a pushing method, the battery can quickly enter and leave the channel. At the same time, it can also reduce the risk of interference between the battery and the outlet, thereby improving the rhythm of battery flipping and further improving the manufacturing efficiency of the battery.

[0012] According to some embodiments of the present application, the rotation axis is parallel to the first direction.

[0013] In the above scheme, by setting the rotation axis parallel to the first direction, the risk of the battery in the constrained space and capable of moving along the first direction being thrown out of the constrained space due to inertia and detaching from the constrained space when the rotation mechanism drives the flipping platform to rotate can be reduced, thereby improving the flipping quality of the battery and further improving the manufacturing efficiency of the battery.

[0014] According to some embodiments of the present application, the flip platform includes a first support member and a second support member, which are arranged opposite to each other along a second direction. The first support member and the second support member are used to constrain the battery in the second direction, and the first direction and the second direction are perpendicular to each other.

[0015] In the above scheme, by setting relative first and second support members in the second direction to constrain the battery in the second direction, on the one hand, the battery can move between the first and second support members to enter or leave the constrained space; on the other hand, it can provide constraints for the battery, reducing the risk of the battery escaping from the constrained space when the flip platform switches from the first position to the second position, and can enable the flipping device to flip the battery quickly, so that the battery has a faster flipping rhythm, thereby making the battery have higher manufacturing efficiency.

[0016] According to some embodiments of the present application, the first support member includes a first support body and a plurality of first rolling portions, wherein the plurality of first rolling portions are rollably disposed on the first support body for rolling contact with a surface of the battery facing away from the second support member.

[0017] In the above scheme, by providing multiple first rolling parts, the surface of the battery is in rolling contact with the multiple first rolling parts. On the one hand, the battery can be constrained so that the battery can stably follow the rotation of the flip platform to achieve posture switching; on the other hand, the battery can be allowed to move along the first direction in the constrained space, thereby improving the efficiency of the battery entering or leaving the accommodation space, improving the rhythm of battery flipping, and thus improving the manufacturing efficiency of the battery; on the other hand, because there is rolling contact between the battery and the first support member, the friction force generated during the movement of the battery in the constrained space has less effect on the surface of the battery, reducing the damage to the battery surface due to flipping the battery, so that the battery has higher quality.

[0018] According to some embodiments of the present application, the second support member includes a second support body and a plurality of second rolling portions, and the plurality of second rolling portions are rollably disposed on the second support body for rolling contact with a surface of the battery facing away from the first support member.

[0019] In the above scheme, by providing multiple second rolling parts, the surface of the battery is in rolling contact with the multiple second rolling parts. On the one hand, the battery can be constrained so that the battery can stably follow the rotation of the flip platform to achieve posture switching; on the other hand, the battery can be allowed to move along the first direction within the constrained space, thereby improving the efficiency of the battery entering or leaving the accommodation space, improving the rhythm of battery flipping, and thus improving the manufacturing efficiency of the battery; on the other hand, because there is rolling contact between the battery and the second support member, the friction force generated during the movement of the battery in the constrained space has less effect on the surface of the battery, reducing the damage to the battery surface due to flipping the battery, so that the battery has higher quality.

[0020] According to some embodiments of the present application, the flip platform also includes a third support member, which is located between the first support member and the second support member, and the third support member connects the first support member and the second support member. The third support member is used to constrain the battery in a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0021] In the above solution, by setting a third support member, the battery can be constrained in the third direction, so that the battery switches from the first posture to the second posture as the flip platform rotates, reducing the risk of the battery escaping from the constrained space in the third direction, thereby making the battery have a higher flipping rhythm, and further making the battery have higher manufacturing efficiency.

[0022] According to some embodiments of the present application, the third support member includes a third support body and a plurality of third rolling portions, and the plurality of third rolling portions are rollably disposed on the third support body for rolling contact with the surface of the battery in the third direction.

[0023] In the above scheme, by providing multiple third rolling parts, the surface of the battery is in rolling contact with the multiple third rolling parts. On the one hand, the battery can be constrained so that the battery can stably follow the rotation of the flip platform to achieve posture switching; on the other hand, the battery can be allowed to move along the first direction in the constrained space, thereby improving the efficiency of the battery entering or leaving the accommodation space, improving the rhythm of battery flipping, and thus improving the manufacturing efficiency of the battery; on the other hand, because there is rolling contact between the battery and the third support member, the friction force generated during the movement of the battery in the constrained space has less effect on the surface of the battery, reducing the damage to the battery surface due to flipping the battery, so that the battery has higher quality.

[0024] According to some embodiments of the present application, along the second direction, the distance between the first support member and the second support member is adjustable.

[0025] In the above solution, by arranging the first support member and the second support member to be positionally adjustable along the second direction, the size of the constraint space in the second direction can be adjusted to accommodate batteries of different specifications, thereby improving the compatibility of the flip device.

[0026] According to some embodiments of the present application, the first support member includes a first support body, the first support body is formed with a first strip hole, the length direction of the first strip hole is parallel to the second direction, the first support member is connected to the third support member through a first connecting member passing through the first strip hole, and the first connecting member is configured to cooperate with the first strip hole in an adjustable position along the second direction.

[0027] In the above scheme, a first strip hole extending along the second direction is provided on the first support body, and the first support body and the third support member are connected by a first connecting member passing through the first strip hole, so that the first support member can move along the second direction relative to the third support member through the mutual cooperation of the first connecting member and the first strip hole, thereby adjusting the positional relationship between the first support member and the second support member in the second direction, and then realizing the adjustment of the size of the constraint space in the second direction to adapt to batteries of different specifications.

[0028] According to some embodiments of the present application, the flip platform further includes a limit member connected to the second support member. Along the third direction, the limit member and the third support member are relatively spaced apart to limit the displacement of the battery in the third direction.

[0029] In the above solution, by setting a limit member and cooperating with the third support member, the battery can be constrained in the third direction, reducing the risk of the battery escaping from the third direction when the flip platform rotates, thereby making the battery have a higher flipping rhythm, and further making the battery have higher manufacturing efficiency.

[0030] According to some embodiments of the present application, the distance between the limiting member and the third supporting member is adjustable along the third direction.

[0031] In the above solution, by arranging the position of the limiting member and the third support member to be adjustable along the third direction, the size of the constraint space in the third direction can be adjusted to accommodate batteries of different specifications and improve the compatibility of the flip device.

[0032] According to some embodiments of the present application, the limiting member includes a first part and a second part that are connected to each other, the first part and the third support member are arranged relative to each other along a third direction, the second part is formed with a second strip hole, the length direction of the second strip hole is parallel to the third direction, the limiting member is connected to the second support member through the second strip hole via a second connecting member, and the second connecting member is configured to cooperate with the second strip hole in an adjustable position along the third direction.

[0033] In the above solution, the position-limiting member has a simple structure and is easy to manufacture. By providing a second strip hole extending along the third direction on the second portion, and connecting the position-limiting member and the second support member via the second connecting member passing through the second strip hole, the position-limiting member can be moved relative to the second support member along the third direction through the interaction between the second connecting member and the second strip hole, thereby adjusting the positional relationship between the first portion and the third support member in the third direction, thereby achieving adjustment of the size of the constraint space in the third direction to accommodate batteries of different specifications.

[0034] According to some embodiments of the present application, the flip platform is configured to rotate 90° under the drive of the rotation mechanism to switch from the first position to the second position.

[0035] In the above scheme, by limiting the rotation angle between the first position and the second position to 90°, the battery located in the constrained space can be flipped 90° each time the rotation mechanism is driven, so that the battery can be quickly switched from a lying position to an upright position or from an upright position to a lying position, so that the battery can be quickly flipped to the required position for the next processing step, thereby improving the manufacturing efficiency of the battery.

[0036] According to some embodiments of the present application, there are multiple flip platforms, and the multiple flip platforms are arranged around a rotation axis. The multiple flip platforms are configured to rotate along the rotation axis so that each flip platform switches cyclically between a first position and a second position.

[0037] In the above solution, by setting up multiple flipping platforms, multiple batteries can be efficiently and continuously delivered into the corresponding confined spaces in sequence, so that the batteries can be flipped continuously, making the battery flipping rhythm fast and the battery manufacturing efficiency high.

[0038] According to some embodiments of the present application, the flipping device further comprises a frame, and the flipping platform is rotatably disposed on the frame via a rotating shaft. The rotating mechanism comprises a driving member and a transmission member, and the driving member is connected to the rotating shaft via the transmission member to drive the flipping platform to rotate.

[0039] In the above scheme, by setting up a frame, the flip platform can rotate around the rotation axis under the action of the driving member and the transmission member, so that it can switch from the first position to the second position, so that the battery corresponding to the first position can enter the constrained space and follow the flip platform to switch to the second posture, and finally leave the constrained space from the position corresponding to the second position to enter the next processing step, thereby realizing rapid flipping of the battery and improving the manufacturing efficiency of the battery.

[0040] In a second aspect, some embodiments of the present application provide a battery flipping method, which is applied to any flipping device of the first aspect. The flipping method includes the following steps:

[0041] placing the battery in a first posture into the constraint space of the flip platform;

[0042] Rotating the flip platform so that the flip platform switches from the first position to the second position, so that the battery flips to the second posture;

[0043] Remove the battery from the confined space.

[0044] In a third aspect, some embodiments of the present application further provide a battery manufacturing apparatus comprising a feed conveyor line, a discharge conveyor line, and the flipping device of any one of the first aspects. When the flipping platform is in a first position, the feed conveyor line supplies batteries in a first posture to the flipping platform; when the flipping platform is in a second position, the discharge conveyor line receives batteries that have left the flipping platform and are in a second posture.

[0045] In the above scheme, through the flipping device provided by the first aspect, in conjunction with the feed conveyor line set corresponding to the first position and the discharge conveyor line set corresponding to the second position, the battery can quickly enter the constrained space at the position corresponding to the first position, follow the rotation of the flipping platform to switch to the second position, and the battery can be quickly taken over by the discharge conveyor line corresponding to the second position to be transported to the next processing step, thereby realizing rapid flipping of the battery and improving the manufacturing efficiency of the battery.

[0046] According to some embodiments of the present application, the battery manufacturing equipment further includes a pushing mechanism, which is used to push the battery into or out of the confined space.

[0047] In the above solution, by providing a pushing mechanism, the battery can be pushed efficiently, so that the battery quickly enters or leaves the confined space, thereby improving the battery flipping rhythm and making the battery have higher manufacturing efficiency.

[0048] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0063] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0064] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs.

The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0065] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0066] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0067] The term "and / or" in this application simply describes an association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist at the same time, and B exists. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0068] In this application, the battery may include a lithium-ion battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, or a magnesium-ion battery, etc., and the embodiments of this application are not limited to this. The battery may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of this application are not limited to this.

[0069] Improving battery manufacturing efficiency is a pressing technical challenge in battery technology. During the battery manufacturing process, batteries may be required to be in different positions, such as lying flat or standing upright. Therefore, flipping the battery is an essential step in the manufacturing process.

[0070] Currently, the device used to flip a battery includes a lifting mechanism, a flipping mechanism, and a clamping mechanism. The clamping mechanism clamps the battery, the flipping mechanism flips the battery cell, and the lifting mechanism lifts and lowers the battery to reduce interference with the outside world. The battery flipping action can be broken down into at least five steps: clamping - lifting - flipping - lowering - unclamping - resetting. This affects the manufacturing cycle and leads to low battery manufacturing efficiency. At the same time, because the battery is flipped by clamping, there is a risk of the battery slipping and flying due to inertia, which also affects the battery manufacturing efficiency.

[0071] In view of this, in order to improve the problem of slow battery flipping rhythm affecting battery manufacturing efficiency, some embodiments of the present application provide a flipping device, which includes a flipping platform and a rotating mechanism. The flipping platform has a constrained space for accommodating the battery to constrain the posture of the battery. The rotating mechanism is connected to the flipping platform and is used to drive the flipping platform to rotate around the rotation axis. The flipping platform is configured to switch from a first position to a second position under the drive of the rotating mechanism. When the flipping platform is in the first position, the battery enters the channel in a first posture, and when the flipping platform is in the second position, the battery flips from the first posture to the second posture and leaves the constrained space in the second posture.

[0072] In the above scheme, the process of flipping the battery using the flipping device can be broken down into three steps: the battery enters the constrained space of the flipping platform, the flipping platform rotates, and the battery leaves the constrained space. Therefore, flipping the battery using the flipping device, so that the battery switches from a first posture to a second posture, can effectively improve the battery flipping rhythm, resulting in higher flipping efficiency and thus improved battery manufacturing efficiency. Furthermore, during the flipping process, the battery switches postures as the flipping platform switches position. Since the battery is constrained in the constrained space, the risk of the battery slipping and being thrown away due to inertia is low, the flipping quality is high, and thus the battery manufacturing efficiency is high.

[0073] The flipping device disclosed in the embodiment of the present application includes but is not limited to flipping a battery to switch the posture of the battery (for example, switching from an upright posture to a lying posture, or from a lying posture to an upright posture), and can also flip other workpieces that require posture switching.

[0074] The flipping device disclosed in the embodiments of the present application includes but is not limited to applications in battery manufacturing equipment, and can also be applied to other manufacturing equipment for workpieces that require posture switching.

[0075] This application provides a flip device, see Figure 1-Figure 5 , Figure 1 This is a three-dimensional diagram of the flip device in some embodiments of the present application. Figure 2 This is a top view of the flip device in some embodiments of the present application. Figure 3 This is a side view of multiple flip platforms in some embodiments of the present application. Figure 4 This is a schematic diagram of a flip platform in some embodiments of the present application. Figure 5 Schematic diagram of a flip device and a battery in some embodiments of the present application.

[0076] The flipping device 100 includes a flipping platform 10 and a rotating mechanism 20. The flipping platform 10 has a constrained space 10a for accommodating the battery 2000 to constrain the posture of the battery 2000. The rotating mechanism 20 is connected to the flipping platform 10 and is used to drive the flipping platform 10 to rotate around the rotation axis s. The flipping platform 10 is configured to switch from a first position to a second position under the drive of the rotating mechanism 20. When the flipping platform 10 is in the first position, the battery 2000 enters the constrained space 10a in the first posture. When the flipping platform 10 is in the second position, the battery 2000 flips from the first posture to the second posture and leaves the constrained space 10a in the second posture.

[0077] The flip platform 10 can provide a confined space 10a for the battery 2000. The confined space 10a accommodates the battery 2000 and can constrain the battery 2000, allowing the battery 2000 to rotate with the flip platform 10. At the same time, during the rotation of the flip platform 10, the battery 2000 will not rotate within the confined space 10a. "Posture" can be understood as the position of the battery 2000 in space. For example, with a horizontal plane as a reference, the posture can include an upright posture upright on the horizontal plane or a flat posture lying flat on the horizontal plane.

[0078] In some embodiments, the confined space 10a can be formed by multiple components of the flip platform 10. For example, the flip platform 10 can include two opposing support members, which are spaced apart to form the confined space 10a and provide confinement for the battery 2000 located between the two support members. The battery 2000 enters or leaves the confined space 10a from the sides of the two support members. For another example, the flip platform 10 can include three support members, two of which are spaced apart from each other, and another support member is located between the two opposing support members. The three support members together form the confined space 10a. When the flip platform 10 is in the first position, the other support member supports the battery 2000, overcoming the gravity of the battery 2000. During the rotation of the flip platform 10, one of the two support members supports the battery 2000 to prevent it from escaping.

[0079] For example, in some embodiments below, the first posture of the battery 2000 may be considered as the posture of the battery 2000 when it is upright, and the second posture of the battery 2000 may be considered as the posture of the battery 2000 when it is lying flat. In other embodiments, the first posture of the battery 2000 may be considered as the posture of the battery 2000 when it is lying flat or in other postures, and the second posture of the battery 2000 may be considered as the posture of the battery 2000 when it is upright or in other postures.

[0080] The rotation mechanism 20 is a mechanism capable of driving the flip platform 10 to rotate about a rotation axis s. For example, the rotation mechanism 20 may include a motor and a timing belt. The flip platform 10 is rotatably mounted on the frame 30 via a rotating shaft 31. The motor drives the rotating shaft 31 via the timing belt, thereby driving the flip platform 10 to rotate. In some embodiments, the motor may be a servo motor. In some embodiments, the rotation mechanism 20 may drive the flip platform 10 to rotate by 90° or other angles.

[0081] “The flip platform 10 is configured to switch from the first position to the second position under the drive of the rotation mechanism 20” can be understood as the flip platform 10 can be rotated from the first position to the second position under the drive of the rotation mechanism 20. Figure 4 , Figure 4 The flip platform 10 on the middle right is drawn with a solid line, which may represent that the flip platform 10 is in the first position. Figure 4 The flip platform 10 on the left side is drawn with a dotted line, which may represent that the flip platform 10 is in the second position.

[0082] "When the flip platform 10 is in the first position, the battery 2000 enters the confined space 10a in the first posture" can be understood as follows: the battery 2000 in the first posture is transported by the feed conveyor line 200. When the flip platform 10 is in the first position, the entrance 10b of the confined space 10a for the battery 2000 to enter can correspond to the incoming direction of the battery 2000, so that the battery 2000 can enter the confined space 10a in the first posture. In some embodiments, when the first posture of the battery 2000 is an upright posture, the first position can be understood as the flip platform 10 being in a position that allows the battery 2000 to stand upright in the flip platform 10, for example, a position that can provide support for the bottom surface of the battery 2000 so that the battery 2000 stands upright, or a position that can provide an upward force to the battery 2000 to overcome gravity so that the battery 2000 stands upright.

[0083] "When the flip platform 10 is in the second position, the battery 2000 flips from the first posture to the second posture and leaves the confined space 10a in the second posture" can be understood as follows: the flip platform 10 is driven by the rotating mechanism 20 to rotate from the first position to the second position, and the battery 2000 located in the confined space 10a follows the rotation and switches from the first posture to the second posture. At this time, the outlet 10c of the confined space 10a for the battery 2000 to leave can correspond to the discharge direction, so that the battery 2000 leaves the confined space 10a in the second posture to be received by the discharge conveyor line 300 and transported to the next processing step. In some embodiments, when the second posture of the battery 2000 is a lying posture, the second position can be understood as the flip platform 10 being in a position that allows the battery 2000 to lie flat on the flip platform 10, for example, a position that can provide support for the side of the battery 2000 so that the battery 2000 lies flat, or a position that can provide an upward force to the battery 2000 to overcome gravity so that the battery 2000 lies flat.

[0084] In the above scheme, the process of flipping the battery 2000 by the flipping device 100 can be decomposed into three steps: the battery enters the confined space of the flipping platform, the flipping platform is rotated, and the battery leaves the confined space. To this end, flipping the battery 2000 by the flipping device 100 so that the battery 2000 switches from the first posture to the second posture can effectively improve the flipping rhythm of the battery 2000, so that the battery 2000 has a higher flipping efficiency, thereby improving the manufacturing efficiency of the battery 2000. At the same time, during the flipping process of the battery 2000, the battery 2000 switches its posture as the position of the flipping platform 10 switches. The battery 2000 is confined in the confined space, so the risk of the battery 2000 slipping and flying due to inertia is low, the flipping quality is high, and thus the manufacturing efficiency of the battery is high.

[0085] According to some embodiments of this application, see Figure 5 The confined space 10a includes an inlet 10b and an outlet 10c. The inlet 10b allows the battery 2000 to enter the confined space 10a, and the outlet 10c allows the battery 2000 to leave the confined space 10a.

[0086] The entrance 10b is the portion of the confined space 10a through which the battery 2000 is allowed to enter, and the exit 10c is the portion of the confined space 10a through which the battery 2000 is allowed to exit. For example, the turning platform 10 has a first opening that communicates with the confined space 10a to form the entrance 10b, allowing the battery 2000 to enter the confined space 10a; and a second opening that communicates with the confined space 10a to form the exit 10c, allowing the battery 2000 to exit the confined space 10a.

[0087] In some embodiments, the inlet 10b and outlet 10c are located at different positions on the flip platform 10, allowing the battery 2000 to exit the confined space 10a through different parts of the confined space 10a. This allows the inlet conveyor line 200 and the outlet conveyor line 300 to be located at different positions to reduce the risk of mutual interference when arranging the inlet conveyor line 200 and the outlet conveyor line 300. For example, along a straight line, the inlet 10b and outlet 10c are located at opposite ends of the confined space 10a, allowing the battery 2000 to enter and exit the confined space 10a directly. Alternatively, the inlet 10b and outlet 10c are oriented perpendicular to each other.

[0088] In the above scheme, by setting the inlet 10b and the outlet 10c, the battery 2000 is limited to enter and leave the constrained space 10a from different parts, thereby simplifying the movement of the battery 2000 in and out, reducing the risk of interference between the battery 2000 in and out, and improving the flipping rhythm of the battery 2000, thereby enabling the battery 2000 to have higher manufacturing efficiency.

[0089] In some embodiments, the portion of the confined space 10a for the battery 2000 to enter and exit may be the same portion. Before the battery 2000 enters the confined space 10a, the battery 2000 in the confined space 10a may be discharged.

[0090] According to some embodiments of this application, see Figure 6 and Figure 7 , Figure 6 This is a side view of the flip platform 10 in some embodiments of the present application. Figure 7 1 is a perspective view of the flip platform 10 in some embodiments of the present application. The inlet 10b and the outlet 10c are opposite to each other along the first direction x.

[0091] In some embodiments, the confined space 10 a allows the battery 2000 to move along a first direction x to enter or exit the confined space 10 a.

[0092] In some embodiments, the confined space 10a can be regarded as a channel for the battery 2000 to move in the confined space 10a along the first direction x. Along the first direction x, one end of the confined space 10a forms an inlet 10b, and the other end forms an outlet 10c.

[0093] For example, one or more batteries 2000 in a first posture are transported by the feed conveyor line 200. When the flip platform 10 is in the first position, the batteries 2000 can enter the confined space 10a through the entrance 10b in the first posture. The one or more batteries 2000 can enter the confined space 10a through inertia during transportation or be pushed into the confined space 10a by a pushing mechanism along a linear trajectory in the first direction x. The flip platform 10 is driven by the rotation mechanism 20 to rotate to the second position, and the one or more batteries 2000 can be pushed out of the confined space 10a along a linear trajectory in the first direction x by another pushing mechanism.

[0094] In the above scheme, the inlet 10b and the outlet 10c are arranged relative to each other along the first direction x, so that the battery 2000 can move in a straight line along the first direction x in the constrained space 10a, reducing the difficulty of the battery 2000 entering and leaving the channel. For example, by using a pushing method, the battery 2000 can quickly enter and leave the channel. At the same time, it can also reduce the risk of interference between the battery 2000 and the outlet, thereby improving the flipping rhythm of the battery 2000 and further improving the manufacturing efficiency of the battery 2000.

[0095] In some other embodiments, the orientation of the inlet 10b and the orientation of the outlet 10c are not in the same direction. Figure 8 , Figure 8 Schematic diagram of the flip device 100 and the battery 2000 in some other embodiments of the present application. The direction of the inlet 10b can be the first direction x. Figure 8 The battery 2000 is moved downward by the feed conveyor line 200 to enter the confined space 10a. The direction of the outlet 10c can be perpendicular to the first direction x. Figure 8 The battery 2000 moves to the right to leave the confined space 10a and be received by the discharge conveyor line 300. In some embodiments, a solution for enabling the battery 2000 to leave the confined space 10a in another direction may include providing a pushing mechanism within the flip platform 10, which can push the battery 2000 toward the outlet 10c.

[0096] According to some embodiments of the present application, the rotation axis s is parallel to the first direction x.

[0097] In some embodiments, the rotation axis s may be arranged in the same direction as the first direction x.

[0098] In the above scheme, by setting the rotation axis s to be parallel to the first direction x, the risk of the battery 2000 that is in the constrained space 10a and can move along the first direction x being thrown out of the constrained space 10a due to inertia when the rotation mechanism 20 drives the flipping platform 10 to rotate can be reduced, thereby improving the flipping quality of the battery 2000 and further improving the manufacturing efficiency of the battery 2000.

[0099] According to some embodiments of this application, see Figure 6 and Figure 7 The flip platform 10 includes a first support member 11 and a second support member 12. The first support member 11 and the second support member 12 are arranged relatively along the second direction y. The first support member 11 and the second support member 12 are used to constrain the battery 2000 in the second direction y. The first direction x and the second direction y are perpendicular to each other.

[0100] The first support member 11 and the second support member 12 are two components spaced apart from each other. In the second direction y, the first support member 11 and the second support member 12 can constrain the battery 2000, ensuring that the battery 2000 is stably located in the confined space 10a. In some embodiments, the first support member 11 and the second support member 12 form at least part of the confined space 10a of the flip platform 10.

[0101] In some embodiments, the battery 2000 is square, the thickness direction of the battery 2000 can be parallel to the second direction y, the width direction of the battery 2000 can be parallel to the first direction x, and the height direction of the battery 2000 can be parallel to the third direction z. The third direction z, the second direction y and the first direction x are perpendicular to each other.

[0102] In some embodiments, the spacing between the first support member 11 and the second support member 12 in the second direction y can be greater than or equal to the size of the battery 2000 in the second direction y, so as to allow the battery 2000 to enter between the first support member 11 and the second support member 12 along the first direction x, and at the same time, when the flip platform 10 rotates, the first support member 11 and the second support member 12 constrain the battery 2000.

[0103] In the above scheme, by arranging relative first and second support members 11 and 12 in the second direction y to constrain the battery 2000 in the second direction y, on the one hand, the battery 2000 can move between the first support member 11 and the second support member 12 to enter or leave the constrained space 10a; on the other hand, it can provide constraints for the battery 2000, reduce the risk of the battery 2000 escaping from the constrained space 10a when the flip platform 10 switches from the first position to the second position, and enable the flipping device 100 to quickly flip the battery 2000, so that the battery 2000 has a faster flipping rhythm, thereby making the battery 2000 have a higher manufacturing efficiency.

[0104] According to some embodiments of this application, see Figure 6 and Figure 7 The first support member 11 includes a first support body 110 and a plurality of first rolling portions 111 . The plurality of first rolling portions 111 are rollably disposed on the first support body 110 for rolling contact with a surface of the battery 2000 that is away from the second support member 12 .

[0105] In some embodiments, the first support body 110 is a supporting portion of the first support member 11, and the first support body 110 is mounted with a plurality of first rolling portions 111. For example, the first support body 110 is plate-shaped and connected to the second support member 12 via other components. The first support body 110 has an end surface facing the second support member 12, and the plurality of first rolling portions 111 are disposed on the end surface facing the second support member 12.

[0106] The first rolling portion 111 may include a roller disposed on the first support body 110. Multiple first rolling portions 111 are arranged along the first direction x. When the battery 2000 is located in the confined space 10a, that is, between the first support member 11 and the second support member 12, the rollers of the first rolling portion 111 can roll in contact with the surface of the battery 2000.

[0107] In the above scheme, by providing multiple first rolling parts 111, the surface of the battery 2000 is in rolling contact with the multiple first rolling parts 111. On the one hand, the battery 2000 can be constrained so that the battery 2000 can stably follow the rotation of the flip platform 10 to achieve posture switching; on the other hand, the battery 2000 can be allowed to move along the first direction x in the constrained space 10a, thereby improving the efficiency of the battery 2000 entering or leaving the accommodation space, improving the rhythm of the battery 2000 flipping, and thus improving the manufacturing efficiency of the battery 2000; on the other hand, because there is rolling contact between the battery 2000 and the first support member 11, the friction force generated during the movement of the battery 2000 in the constrained space 10a has little effect on the surface of the battery 2000, reducing the damage to the surface of the battery 2000 due to flipping the battery 2000, so that the battery 2000 has higher quality.

[0108] According to some embodiments of the present application, the second support member 12 includes a second support body 120 and a plurality of second rolling portions 121 . The plurality of second rolling portions 121 are rollably disposed on the second support body 120 for rolling contact with a surface of the battery 2000 facing away from the first support member 11 .

[0109] In some embodiments, the second support body 120 serves as a supporting portion for the second support member 12, and the second support body 120 is provided with a plurality of second rolling portions 121. For example, the second support body 120 is plate-shaped, and the first support body 110 is connected to the first support member 11 via other components. A receiving groove is formed on the surface of the second support body 120 facing the first support member 11, and the plurality of second rolling portions 121 are disposed in the receiving groove, with the portion of the second rolling portion 121 configured for rolling contact with the battery 2000 protruding from the receiving groove.

[0110] In some embodiments, the second support body 120 is provided with a connecting portion 123, which is located on a surface of the second support body 120 facing away from the first support member 11. The connecting portion 123 can be connected to the rotation mechanism 20. For example, the connecting portion 123 is connected to the rotation shaft 31, and the rotation mechanism 20 drives the rotation shaft 31 to rotate to drive the flip platform 10 to rotate.

[0111] The second rolling portion 121 may include a roller disposed on the second support body 120. Multiple second rolling portions 121 are arranged along the first direction x. When the battery 2000 is located in the confined space 10a, that is, between the first support member 11 and the second support member 12, the rollers of the second rolling portion 121 can roll in contact with the surface of the battery 2000.

[0112] In some embodiments, the first support member 11 includes multiple first rolling parts 111, the second support member 12 includes multiple second rolling parts 121, and the two surfaces of the battery 2000 opposite to each other in the second direction y roll with the multiple first rolling parts 111 and the multiple second rolling parts 121 respectively.

[0113] In the above scheme, by providing multiple second rolling parts 121, the surface of the battery 2000 is in rolling contact with the multiple second rolling parts 121. On the one hand, the battery 2000 can be constrained so that the battery 2000 can stably follow the rotation of the flip platform 10 to achieve posture switching; on the other hand, the battery 2000 can be allowed to move along the first direction x in the constrained space 10a, thereby improving the efficiency of the battery 2000 entering or leaving the accommodation space, improving the rhythm of the battery 2000 flipping, and thus improving the manufacturing efficiency of the battery 2000; on the other hand, because there is rolling contact between the battery 2000 and the second support member 12, the friction force generated during the movement of the battery 2000 in the constrained space 10a has little effect on the surface of the battery 2000, reducing the damage to the surface of the battery 2000 due to flipping the battery 2000, so that the battery 2000 has higher quality.

[0114] According to some embodiments of this application, see Figure 6 and Figure 7 The flip platform 10 also includes a third support member 13, which is located between the first support member 11 and the second support member 12. The third support member 13 connects the first support member 11 and the second support member 12. The third support member 13 is used to constrain the battery 2000 in the third direction z. The first direction x, the second direction y and the third direction z are perpendicular to each other.

[0115] The third support member 13 is disposed between the first support member 11 and the second support member 12 and is used to constrain the battery 2000 in the third direction z. For example, when the flip platform 10 is in the first position, the third support member 13 supports the battery 2000, overcoming the weight of the battery 2000. When the flip platform 10 switches from the first position to the second position, the second support member 12 supports the battery 2000, ultimately overcoming the weight of the battery 2000.

[0116] In some embodiments, as Figure 4The spacing between the first support member 11 and the second support member 12 can be greater than the dimension of the battery 2000 in the second direction y, allowing a gap to exist between the battery 2000 and the first support member 11 and / or the second support member 12. When the flip platform 10 is in the first position, the third support member 13 supports the battery 2000, overcoming the weight of the battery 2000. When the flip platform 10 switches from the first position to the second position, the battery 2000 tilts and is supported by the second support member 12. Ultimately, the battery 2000 switches from an upright position to a lying position, with the second support member 12 supporting the battery 2000 and overcoming the weight of the battery 2000.

[0117] In the above scheme, by setting the third support member 13, the battery 2000 can be constrained in the third direction z, so that the battery 2000 switches from the first posture to the second posture as the flip platform 10 rotates, reducing the risk of the battery 2000 escaping from the constrained space 10a in the third direction z, thereby making the battery 2000 have a higher flipping rhythm, and further making the battery 2000 have a higher manufacturing efficiency.

[0118] According to some embodiments of this application, see Figure 6 and Figure 7 The third support member 13 includes a third support body 130 and a plurality of third rolling portions 131 . The plurality of third rolling portions 131 are rollably disposed on the third support body 130 for rolling contact with the surface of the battery 2000 in the third direction z.

[0119] In some embodiments, the third support body 130 serves as the supporting portion of the third support member 13, and the third support body 130 is provided with a plurality of third rolling portions 131. For example, the third support body 130 is plate-shaped and connects the first support body 110 and the second support body 120. A receiving groove is formed on the surface of the second support body 120 located between the first support body 110 and the second support body 120. The plurality of third rolling portions 131 are disposed in the receiving groove, and the portions of the third rolling portions 131 that are intended for rolling contact with the battery 2000 protrude from the receiving groove.

[0120] The third rolling portion 131 may include a roller disposed on the third support body 130. Multiple third rolling portions 131 are arranged along the first direction x. When the battery 2000 is within the confined space 10a, the rollers of the third rolling portion 131 can roll in contact with the surface of the battery 2000. For example, when the battery 2000 enters the confined space 10a in an upright position, the bottom surface of the battery 2000 rolls in contact with the third support body 130.

[0121] In the above scheme, by providing multiple third rolling parts 131, the surface of the battery 2000 is in rolling contact with the multiple third rolling parts 131. On the one hand, the battery 2000 can be constrained so that the battery 2000 can stably follow the rotation of the flip platform 10 to achieve posture switching; on the other hand, the battery 2000 can be allowed to move along the first direction x in the constrained space 10a, thereby improving the efficiency of the battery 2000 entering or leaving the accommodation space, improving the rhythm of the battery 2000 flipping, and thus improving the manufacturing efficiency of the battery 2000; on the other hand, because there is rolling contact between the battery 2000 and the third support member 13, the friction force generated during the movement of the battery 2000 in the constrained space 10a has little effect on the surface of the battery 2000, reducing the damage to the surface of the battery 2000 due to flipping the battery 2000, so that the battery 2000 has higher quality.

[0122] According to some embodiments of the present application, along the second direction y, the distance between the first support member 11 and the second support member 12 is adjustable.

[0123] In some embodiments, the first support member 11 is positionally adjustable relative to the third support member 13 along the second direction y to adjust the distance between the first support member 11 and the second support member 12 in the second direction y. In some embodiments, the second support member 12 is positionally adjustable relative to the third support member 13 along the second direction y to adjust the distance between the first support member 11 and the second support member 12 in the second direction y. In other embodiments, the first support member 11 is positionally adjustable relative to the third support member 13 along the second direction y, and the second support member 12 is positionally adjustable relative to the third support member 13 along the second direction y to adjust the distance between the first support member 11 and the second support member 12 in the second direction y.

[0124] For example, taking "the position of the first support member 11 can be adjusted relative to the third support member 13 along the second direction y" as an example, a position adjustment structure can be provided between the third support member 13 and the first support member 11. For example, the first support member 11 is provided with a strip hole extending along the second direction y, and a connecting member passes through the strip hole to achieve the connection between the third support member 13 and the first support member 11, and the connecting member can slide relative to the strip hole. For another example, the third support member 13 is provided with a cylinder, and the cylinder's telescopic rod moves along the second direction y. The first support member 11 is arranged on the telescopic rod. The cylinder drives the third support member 13 to adjust its position in the second direction y.

[0125] In the above solution, by setting the first support member 11 and the second support member 12 to be adjustable in position along the second direction y, the size of the constraint space 10a in the second direction y can be adjusted to accommodate batteries 2000 of different specifications and improve the compatibility of the flip device 100.

[0126] According to some embodiments of this application, see Figure 7 and Figure 9 , Figure 9 Schematic diagram of the first support member 11 in some embodiments of the present application.

[0127] The first support member 11 includes a first support body 110, and the first support body 110 is formed with a first strip hole 1100. The length direction of the first strip hole 1100 is parallel to the second direction y. The first support member 11 is connected to the third support member 13 through a first connecting member passing through the first strip hole 1100. The first connecting member is configured to cooperate with the first strip hole 1100 in an adjustable position along the second direction y.

[0128] The length direction of the first strip hole 1100 is the direction in which the first strip hole 1100 has the largest size. For example, the first strip hole 1100 is an elongated hole or a waist-shaped hole extending along the second direction y. The first strip hole 1100 passes through the first support body 110 along the third direction z.

[0129] The first connecting member is a connecting component that can pass through the first strip-shaped hole 1100 and slidably engage with the first strip-shaped hole 1100. For example, the first connecting member includes a bolt. The third support body 130 of the third support member 13 is provided with a threaded hole. The bolt passes through the first strip-shaped hole 1100 and is connected to the threaded hole. The nut of the bolt can abut against the surface of the first support body 110 facing away from the third support body 130 to ensure a stable connection between the first support body 110 and the third support body 130. When the position of the first support member 11 needs to be adjusted in the second direction y, the bolt is loosened, the first support body 110 is allowed to slide relative to the first connecting member, and then the bolt is tightened.

[0130] In the above scheme, a first strip hole 1100 extending along the second direction y is provided on the first support body 110, and the first support body 110 and the third support member 13 are connected by a first connecting member passing through the first strip hole 1100, so that the first support member 11 can move along the second direction y relative to the third support member 13 through the mutual cooperation of the first connecting member and the first strip hole 1100, so as to adjust the positional relationship between the first support member 11 and the second support member 12 in the second direction y, thereby realizing the adjustment of the size of the constraint space 10a in the second direction y to adapt to batteries 2000 of different specifications.

[0131] In the third direction z, the stopper 14 is spaced relative to the third support member 13. In some embodiments, the first support member 11, the second support member 12, the third support member 13, and the stopper 14 collectively define a constrained space 10a. The constrained space 10a has an inlet 10b and an outlet 10c disposed opposite each other along the first direction x. During the rotation of the flip platform 10, the first support member 11 and the second support member 12 provide constraints for the battery 2000 in the second direction y, while the third support member 13 and the stopper 14 provide constraints for the battery 2000 in the third direction z.

[0132] In some embodiments, the limiting member 14 may be connected to the second support member 12. In other embodiments, the limiting member 14 may be connected to the first support member 11.

[0133] In some embodiments, when the battery 2000 is located in the confined space 10a, the portion of the battery 2000 facing away from the third support member 13 may not contact the stopper 14. The stopper 14 may function to limit the displacement of the battery 2000 when the battery 2000 is subjected to excessive centrifugal force due to the rotation of the flip platform 10. In some embodiments, the centrifugal force applied to the battery 2000 due to the rotation of the flip platform 10 may be relatively small, so that the stopper 14 does not contact the battery 2000.

[0134] In the above scheme, by setting the limit member 14 and cooperating with the third support member 13, the battery 2000 can be constrained in the third direction z, reducing the risk of the battery 2000 escaping from the third direction z when the flip platform 10 rotates, so that the battery 2000 has a higher flipping rhythm, and thus the battery 2000 has a higher manufacturing efficiency.

[0135] According to some embodiments of the present application, the distance between the limiting member 14 and the third supporting member 13 is adjustable along the third direction z.

[0136] In some embodiments, the position of the limiting member 14 can be adjusted relative to the second support member 12 along the third direction z to adjust the distance between the limiting member 14 and the third support member 13 in the third direction z.

[0137] For example, taking the example of "the position of the limiter 14 can be adjusted relative to the second support member 12 along the third direction z," a position adjustment structure can be provided between the limiter 14 and the second support member 12. For example, the limiter 14 is provided with a strip hole extending along the third direction z, and a connecting member passes through the strip hole to connect the limiter 14 and the second support member 12, and the connecting member can slide relative to the strip hole. For another example, the second support member 12 is provided with a cylinder, and the cylinder's telescopic rod moves along the third direction z. The limiter 14 is provided on the telescopic rod, and the position of the limiter 14 in the third direction z is adjusted by the cylinder's drive.

[0138] In the above solution, by setting the limiter 14 and the third support member 13 to be adjustable along the third direction z, the size of the constraint space 10a in the third direction z can be adjusted to accommodate batteries 2000 of different specifications and improve the compatibility of the flip device 100.

[0139] According to some embodiments of the present application, see Figure 10 , Figure 10 for Figure 7 Enlarged view of point A in the middle. The limiting member 14 includes a first portion 140 and a second portion 141 that are interconnected. The first portion 140 and the third support member 13 are spaced relative to each other along the third direction z. The second portion 141 is formed with a second strip hole 142. The length direction of the second strip hole 142 is parallel to the third direction z. The limiting member 14 is connected to the second support member 12 via a second connecting member that passes through the second strip hole 142. The second connecting member is configured to adjustably engage with the second strip hole 142 along the third direction z.

[0140] In some embodiments, the first portion 140 may be plate-shaped and spaced apart from the third support member 13 in the third direction z. In other embodiments, a surface of the first portion 140 facing the third support member 13 may be provided with rollers, which may be used to roll in contact with the battery 2000.

[0141] In some embodiments, the second portion 141 may be a bracket, and the number of the second portion 141 may be two, and the two second portions 141 are respectively disposed at opposite ends of the first portion 140 in the first direction x. Figure 10 The second portion 141 is formed with a second strip hole 142 , which passes through the wall of the second portion 141 along the first direction x. The second strip hole 142 may be a long strip hole or a waist-shaped hole extending along the third direction z.

[0142] The second connecting member is a connecting component that can pass through and slidably engage with the second strip-shaped hole 142. For example, the second connecting member includes a bolt. The second support body 120 of the second support member 12 is provided with a threaded hole. The bolt passes through the second strip-shaped hole 142 and connects with the threaded hole. The nut of the bolt can abut against the surface of the second portion 141 facing away from the second support body 120, thereby ensuring a stable connection between the limiting member 14 and the second support body 120. When the position of the limiting member 14 in the third direction z needs to be adjusted, the bolt is loosened, the limiting member 14 is allowed to slide relative to the second connecting member, and then the bolt is tightened.

[0143] In the above solution, the position-limiting member 14 has a simple structure and is easy to manufacture. By providing a second strip-shaped hole 142 extending along the third direction z on the second portion 141 and connecting the position-limiting member 14 to the second support member 12 via the second strip-shaped hole 142, the position-limiting member 14 can be moved relative to the second support member 12 along the third direction z through the interaction between the second strip-shaped hole 142 and the second connector. This allows the position-limiting member 14 to be adjusted relative to the second support member 12 along the third direction z, thereby adjusting the positional relationship between the first portion 140 and the third support member 13 along the third direction z. This allows the size of the constraint space 10a along the third direction z to be adjusted to accommodate batteries 2000 of different specifications.

[0144] According to some embodiments of the present application, the flip platform 10 is configured to rotate 90° under the drive of the rotation mechanism 20 to switch from the first position to the second position.

[0145] In some embodiments, the first posture of the battery 2000 corresponding to the first position can be an upright posture, and the second posture of the battery 2000 corresponding to the second position can be a flat posture. That is, the flip platform 10 is driven by rotation to enable the battery 2000 to switch from the upright posture to the flat posture.

[0146] “The flip platform 10 is configured to rotate 90° under the drive of the rotation mechanism 20 to switch from the first position to the second position” can also be understood as that each drive of the rotation mechanism 20 causes the flip platform 10 to rotate 90° around the rotation mechanism 20.

[0147] In the above scheme, by limiting the rotation angle between the first position and the second position to 90°, the battery 2000 located in the constrained space 10a can be flipped 90° each time the rotation mechanism 20 is driven, so that the battery 2000 can be quickly switched from a lying position to an upright position or from an upright position to a lying position, so that the battery 2000 can be quickly flipped to the required position for processing in the next step, thereby improving the manufacturing efficiency of the battery 2000.

[0148] According to some embodiments of this application, see Figure 3 The flip platforms 10 are arranged in a plurality around a rotation axis s. The flip platforms 10 are configured to rotate along the rotation axis s so that each flip platform 10 switches cyclically between a first position and a second position.

[0149] In some embodiments, the number of the flip platforms 10 can be two, three or four. Figure 3There are four flipping platforms 10. Each flipping platform 10 can be rotated 90° each time the rotating mechanism 20 is driven. Therefore, the four flipping platforms 10 can continuously receive the batteries 2000 conveyed by the feed conveyor belt, and can also continuously convey the flipped batteries 2000 to the discharge conveyor belt.

[0150] In the above scheme, by setting up multiple flipping platforms 10, multiple batteries 2000 can be efficiently and continuously sent into the corresponding confinement space 10a in sequence, so that the batteries 2000 are continuously flipped, so that the flipping rhythm of the batteries 2000 is fast and the manufacturing efficiency of the batteries 2000 is high.

[0151] According to some embodiments of this application, see Figure 1 The flipping device 100 further includes a frame 30, and the flipping platform 10 is rotatably disposed on the frame 30 via a rotating shaft 31. The rotating mechanism 20 includes a driving member 21 and a transmission member 22, and the driving member 21 is connected to the rotating shaft 31 via the transmission member 22 to drive the flipping platform 10 to rotate.

[0152] The frame 30 plays a supporting role. The frame 30 is rotatably provided with a rotating shaft 31. The turning platform 10 is fixed on the rotating shaft 31. The axis of the rotating shaft 31 is the rotation axis s of the turning platform 10.

[0153] The rotation mechanism 20 includes a driving member 21 and a transmission member 22. The driving member 21 can be mounted on a frame 30 and connected to a rotating shaft 31 via the transmission member 22. The power output by the driving member 21 can rotate the rotating shaft 31, thereby rotating the flip platform 10. In some embodiments, the driving member 21 can include a servo motor, and the transmission member 22 can include a synchronous belt drive structure.

[0154] In the above scheme, by setting up the frame 30, the flip platform 10 can rotate around the rotation axis s under the action of the driving member 21 and the transmission member 22, so that it can switch from the first position to the second position, so that the battery 2000 corresponding to the first position can enter the constrained space 10a, and follow the flip platform 10 to rotate to switch to the second posture, and finally leave the constrained space 10a from the position corresponding to the second position to enter the next processing step, thereby realizing the rapid flipping of the battery 2000, thereby improving the manufacturing efficiency of the battery 2000.

[0155] According to some embodiments of the present application, a battery flipping method is provided. Figure 11 , Figure 11 This is a flowchart of a battery flipping method in some embodiments of the present application.

[0156] The battery flipping method 3000 is applied to the flipping device 100 described above, and the method includes the following steps:

[0157] S1, placing the battery 2000 in the first posture into the confined space 10a of the flip platform 10;

[0158] S2, rotating the flip platform 10 so that the flip platform 10 switches from the first position to the second position, so that the battery 2000 flips to the second posture;

[0159] S3. Move the battery 2000 out of the confined space 10a.

[0160] In some embodiments, the battery flipping method 3000 may be performed using the flipping device 100 provided above, so that the battery 2000 is quickly flipped from a first posture to a second posture, for example, from an upright posture to a lying posture.

[0161] In some embodiments, in step S1, a pushing mechanism may be used to place the battery 2000 into the confined space 10a of the flip platform 10. In step S3, another pushing mechanism may be used to push the battery 2000 out of the confined space 10a.

[0162] In the above scheme, the flipping method 3000 of the battery is performed using the flipping device 100, so that the battery 2000 switches from the first posture to the second posture, which can effectively improve the flipping rhythm of the battery 2000, so that the battery 2000 has a higher flipping efficiency, thereby improving the manufacturing efficiency of the battery 2000. At the same time, in the process of flipping the battery 2000, the battery 2000 switches its posture as the position of the flipping platform 10 switches. The battery 2000 is constrained in the constrained space, so the risk of the battery 2000 slipping and flying due to inertia is low, the flipping quality is high, and thus the manufacturing efficiency of the battery is high.

[0163] According to some embodiments of this application, see Figure 12 , Figure 12 Schematic diagram of a battery manufacturing apparatus 1000 in some embodiments of the present application.

[0164] The battery manufacturing equipment 1000 includes a feed conveyor line 200, a discharge conveyor line 300, and the above-described inversion device 100. When the inversion platform 10 is in a first position, the feed conveyor line 200 provides batteries 2000 in a first posture to the inversion platform 10. When the inversion platform 10 is in a second position, the discharge conveyor line 300 receives batteries 2000 that have left the inversion platform 10 and are in a second posture.

[0165] In some embodiments, the feed conveyor line 200 may be an upstream mechanism of the flipping device 100 and may include, but is not limited to, a roller conveyor line or a belt conveyor line. The discharge conveyor line 300 may be a downstream mechanism of the flipping device 100 and may include, but is not limited to, a roller conveyor line or a belt conveyor line. For example, the battery 2000 is conveyed to the flipping device 100 via the feed conveyor line 200 in a first posture. After being flipped by the flipping device 100, the battery 2000 is received by the discharge conveyor line 300 in a second posture and transported to the next processing step.

[0166] “When the flip platform 10 is in the first position, the feeding conveyor line 200 provides the battery 2000 in the first posture to the flip platform 10” can be understood as that the feeding conveyor line 200 is set corresponding to the first position so that the battery 2000 in the first posture on the feeding conveyor line 200 can enter the constrained space 10a.

[0167] "When the flip platform 10 is in the second position, the discharge conveyor line 300 receives the battery 2000 that leaves the flip platform 10 and is in the second posture" can be understood as that the discharge conveyor line 300 is set corresponding to the second position so that the battery 2000 in the second posture can leave the constrained space 10a and be received by the discharge conveyor line 300 to be transported to the next processing step.

[0168] In some embodiments, the battery manufacturing equipment 1000 may include multiple flipping devices 100 , and the battery 2000 may be flipped by the multiple flipping devices 100 to adapt to different processing steps of the battery 2000 .

[0169] In the above scheme, through the flipping device 100 provided in the first aspect, in conjunction with the feed conveyor line 200 set corresponding to the first position and the discharge conveyor line 300 set corresponding to the second position, the battery 2000 can quickly enter the constrained space 10a at the position corresponding to the first position, follow the rotation of the flipping platform 10 to switch to the second position, and enable the battery 2000 to be quickly taken over by the discharge conveyor line 300 corresponding to the second position to be transported to the next processing step, thereby realizing the rapid flipping of the battery 2000, thereby improving the manufacturing efficiency of the battery 2000.

[0170] According to some embodiments of the present application, the battery manufacturing equipment 1000 further includes a pushing mechanism 400 , which is used to push the battery 2000 into or out of the confined space 10 a .

[0171] In some embodiments, the pushing mechanism 400 is a mechanism capable of providing a pushing force to the battery 2000. For example, the pushing mechanism 400 includes but is not limited to a mechanism capable of outputting a pushing force, such as a robotic arm, a linear pushing motor, and a pushing cylinder.

[0172] In some embodiments, the feed conveyor line 200 is provided with a push mechanism 400 that can push the battery 2000 on the feed conveyor line 200 into the confined space 10a. In some embodiments, the discharge conveyor line 300 is provided with a push mechanism 400 that can push the battery 2000 in the confined space 10a out of the confined space 10a and onto the discharge conveyor line 300.

[0173] For example, see Figure 12 The inlet 10b and outlet 10c of the confined space 10a are arranged opposite to each other in the first direction x, and the feed conveying line 200 is arranged corresponding to the inlet 10b. Figure 12 The feeding conveyor line 200 is located above. The discharging conveyor line 300 is set corresponding to the outlet 10c. Figure 12 The discharge conveyor line 300 is located at the bottom. The pushing mechanism that pushes the battery 2000 into the confined space 10a is located at the top, and can output a pushing force from the inlet 10b toward the outlet 10c, allowing the battery 2000 to enter the confined space 10a. The pushing mechanism 400 that pushes the battery 2000 out of the confined space 10a and onto the discharge conveyor line 300 can also be located at the top. It can be pushed by the inlet 10b and output a pushing force from the inlet 10b toward the outlet 10c, allowing the battery 2000 to escape from the outlet 10c and be located on the discharge conveyor line 300.

[0174] In the above solution, by providing the pushing mechanism 400, the battery 2000 can be efficiently pushed so that the battery 2000 quickly enters or leaves the confined space 10a, thereby improving the flipping rhythm of the battery 2000 and making the battery 2000 have higher manufacturing efficiency.

[0175] According to some embodiments of the present application, a flipping device 100 is provided, which is used to flip a battery 2000, and is used to flip the battery 2000 from an upright position to a lying position or from a lying position to an upright position.

[0176] The flipping device 100 includes a flipping platform 10, a rotating mechanism 20, and a frame 30. Multiple flipping platforms 10 are rotatably mounted on the frame 30 via a rotating shaft 31. The rotating mechanism 20 includes a servo motor and a synchronous belt drive structure. The servo motor drives the rotating shaft 31 through the synchronous belt drive structure, causing the multiple flipping platforms 10 to rotate around the rotating shaft 31.

[0177] The tilting platform 10 includes a first support member 11, a second support member 12, a third support member 13, and a stopper 14. The first support member 11 and the second support member 12 are spaced relative to each other along the second direction y. The third support member 13 is located between and connects the first and second support members 11 and 12. The third support member 13 and the stopper 14 are spaced relative to each other along the third direction z. The stopper 14 is located at the end of the second support member 12 facing away from the third support member 13 in the third direction z. The first support member 11, the second support member 12, the third support member 13, and the stopper 14 collectively define a confined space 10a. The confined space 10a is continuous in the first direction x, with an entrance 10b and an exit 10c in the first direction x. The confined space 10a is used to accommodate and confine the battery 2000. The battery 2000 can enter the confined space 10a through the entrance 10b and exit the confined space 10a through the exit 10c. In some embodiments, the distance between the first support member 11 and the second support member 12 can be adjusted to adjust the size of the confined space 10a in the second direction y, thereby accommodating batteries 2000 of different specifications. In some embodiments, the distance between the stopper 14 and the third support member 13 can be adjusted to adjust the size of the confined space 10a in the third direction z, thereby accommodating batteries 2000 of different specifications.

[0178] The flip platform 10 is configured to rotate 90° under the drive of the rotation mechanism 20, switching from a first position to a second position. When the flip platform 10 is in the first position, the battery 2000 enters the passage in a first posture. When the flip platform 10 is in the second position, the battery 2000 flips from the first posture to a second posture and leaves the confined space 10a in the second posture. The first posture of the battery 2000 can be an upright posture, and the second posture of the battery 2000 can be a flat posture.

[0179] When the flipping device 100 is used in a battery manufacturing apparatus 1000, the feed conveyor line 200 of the battery 2000 is set to a first position so that the battery 2000 in a first posture on the feed conveyor line 200 can enter the confined space 10a. The discharge conveyor line 300 of the battery 2000 is set to a second position so that the battery 2000 in a second posture can leave the confined space 10a and be received by the discharge conveyor line 300 for transportation to the next processing step. In some embodiments, the feed conveyor line 200 is provided with a push mechanism 400, which can push the battery 2000 on the feed conveyor line 200 into the confined space 10a. In some embodiments, the discharge conveyor line 300 is provided with a push mechanism 400, which can push the battery 2000 in the confined space 10a out of the confined space 10a and onto the discharge conveyor line 300.

[0180] The process of flipping the battery 2000 by the flipping device 100 can be broken down into three steps: the battery 2000 enters the confined space 10a of the flipping platform 10, the flipping platform 10 rotates, and the battery 2000 leaves the confined space 10a. To this end, flipping the battery 2000 by the flipping device 100 so that the battery 2000 switches from a first posture to a second posture can effectively improve the flipping rhythm of the battery 2000, so that the battery 2000 has a higher flipping efficiency, thereby improving the manufacturing efficiency of the battery 2000. At the same time, during the flipping process of the battery 2000, the battery 2000 switches its posture as the position of the flipping platform 10 switches. The battery 2000 is confined in the confined space 10a, so the risk of the battery 2000 slipping and flying due to inertia is low, the flipping quality is high, and thus the manufacturing efficiency of the battery 2000 is high.

[0181] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
