Reference is made to the accompanying drawings, all of which form a part of this specification. However, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0044] At present, in the battery manufacturing process, various types of processing are required for battery cells. When a turntable is used to transport multiple workpieces, the traditional welding method uses a single rotating device to weld the workpieces on multiple stations in turn. A rotating component can only perform single-sided follow-up swing arm welding, but the swing arm vibrates greatly when it swings back and forth, affecting the accuracy of welding.

[0045] A rotating device provided in an embodiment of the present invention can carry a plurality of working components and can adjust the rotation of the working components, thereby reducing the vibration of the rotating components, so as to improve the accuracy of the entire rotating device.

[0046] In order to achieve the above effects, an embodiment of the present invention provides a rotating device, including a rotating component, on which a plurality of working components are provided, each of which can operate on a workpiece, and the plurality of working components rotate with the rotating component.

[0047] The following is an example of two working components. Figure 1 and Figure 2 As shown, the rotating assembly 110 is configured to be able to rotate around the rotation axis L. Based on different processing requirements, the rotating assembly 110 can be of any shape, and can be a regular shape (i.e., the distances between each position of the rotating assembly 110 along the circumference of the rotation axis L and the rotation axis L are equal), or an irregular shape (i.e., the distances between each position of the rotating assembly 110 along the circumference of the rotation axis L and the rotation axis L are not equal). For ease of description, the following is an embodiment in which the rotating assembly 110 is a disk, and the central axis of the disk coincides with the rotation axis L, and different embodiments can be combined with each other between different technical solutions.

[0048] The rotating assembly 110 includes a plurality of carriers 111 arranged around a rotation axis L. The plurality of carriers 111 include a carrier 1110 and a second carrier 1111, wherein the first carrier 1110 is suitable for correspondingly mounting a first workpiece 201, and the second carrier 1111 is suitable for correspondingly mounting a second workpiece 202. According to different transport requirements, the spacing between the carriers 111 may be uniform or uneven. It should be noted that the shape and structure of each carrier 111 may be the same or different. The plurality of carriers 111 are suitable for mounting a plurality of workpieces 200 in a one-to-one correspondence. The workpiece 200 may be any component. For example, in some embodiments, the workpiece 200 may be a battery cell, and thus, the rotating device 100 of the present invention may be used for welding a battery cell and a current collecting plate, and at this time, the first working assembly 120 and the second working assembly 121 are loaded with a CCD pre-welding guide device.

[0049] like Figure 3 , Figure 4 and Figure 7 As shown, the rotating assembly 110 drives the first working assembly 120 and the second working assembly 121 to rotate, so that the first working assembly 120 and the second working assembly 121 rotate in opposite directions at the same time, so that the first workpiece 201 and the second workpiece 202 corresponding thereto respectively move in opposite directions on the rotating assembly 110 and are processed. It can be understood that when there are multiple working assemblies, the rotation directions of the corresponding multiple workpieces are also different. Preferably, as Figure 4 As shown, the first workpiece 201 and the second workpiece 202 are loaded symmetrically, and a rotating assembly 110 has two 180° loading channels, which reduces the rotation angle of the first workpiece 201 and the second workpiece 202 on the rotating assembly 110, and the functional items on both sides of the rotating assembly 110 are symmetrically distributed, and the first workpiece 201 and the second workpiece 202 on the symmetrical sides can be processed at the same time. When the welding vibrator is symmetrically installed on the first workpiece 201 and the second workpiece 202, simultaneous welding of the symmetrical sides is achieved.

[0050] The rotation plane where the first working component 120 rotates is defined as the first plane, and the rotation plane where the second working component 121 rotates is defined as the second plane. For example, the first working component 120 and the second working component 121 are staggered in height, and the first rotating bracket 2 and the second rotating bracket 3 rotate in two planes parallel to each other, that is, the first plane and the second plane are parallel to each other. If the first working component 120 and the second working component 121 are arranged side by side, the first rotating bracket 2 and the second rotating bracket 3 rotate in the same plane, that is, the first plane and the second plane are coplanar. When the rotating device is actually installed, the first plane and the second plane can be adjusted to be parallel to the horizontal plane, so as to achieve the balance of the overall device when the working components are rotated.

[0051] First, the first working assembly 120 is described, taking the workpiece as a battery cell to be welded as an example. Figure 1 and Figure 2 As shown, the first working assembly 120 is located on the side of each workpiece 200 away from its corresponding carrier 111. It can be understood that one end of any battery cell on which the rotating device 100 is installed can be supported and connected by the carrier 111, and the other end can be directly opposite to the first working assembly 120, so that the first working assembly 120 can process any battery cell. The first working assembly 120 is configured to be able to rotate along a first path around the rotation axis L. In some embodiments, the rotating assembly 110 and the first working assembly 120 may not be connected to each other, and the two may be connected to different driving mechanisms respectively. In other embodiments, the rotating assembly 110 and the first working assembly 120 may be connected to each other so that both can rotate around the rotation axis L at the same time.

[0052] The synchronous rotation between the first working assembly 120 and the second working assembly 121 and the rotating assembly 110 and the driving assembly 140 can be achieved by using a mechanical structure. Figure 3 As shown, the rotating device 100 includes a bracket 131 , and the bracket 131 connects the first working assembly 120 and the second working assembly 121 so that the first working assembly 120 and the second working assembly 121 rotate synchronously with the rotating assembly 110 or the driving assembly 140 .

[0053] like Figure 5 and Figure 6As shown, the first working assembly 120 has a first state and a second state. When the first working assembly 120 is in the first state, the first working assembly 120 is located at the P1 position, and the working assembly 120 is configured to rotate synchronously with the rotating assembly 110 to weld the workpiece 200. When the first working assembly 120 is in the second state, the first working assembly 120 is located at the P2 position, and the first working assembly 120 is configured to rotate displacedly relative to the rotating assembly 110 to adjust the position of the first working assembly 120 relative to the rotating assembly 110 so that the first working part 1201 is suitable for starting welding. It should be noted that the displaced rotation of the first working assembly 120 relative to the rotating assembly 110 is represented by the different angular velocities of the two (which can be different in magnitude or different in direction), and the synchronous rotation is represented by the same angular velocities of the two. Thus, it can be understood that, on the one hand, the first working component 120 can rotate synchronously with the rotating component 110, and during this process, the first working component 120 continues to be in a position suitable for welding the workpiece 200 (at this time, the first working component 120 can be suitable for welding one workpiece 200, and can also be suitable for welding multiple workpieces 200 at the same time), that is, the first state can be a state corresponding to the process of the first working component 120 welding the workpiece 200; on the other hand, the first working component 120 can also rotate relative to the rotating component 110, and the second state corresponds to the process of the first working component 120 being driven to the position ready for the next welding operation after one welding is completed.

[0054] It should be noted that the staggered rotation of the first working component 120 and the rotating component 110 means that during this process, the two are in a relative rotation relationship. Therefore, when the first working component 120 is in the second state, relative to the ground, in another embodiment, the first working component 120 and the rotating component 110 can both rotate, and the rotation speeds of the two are different; in another embodiment, the first working component 120 may not rotate, and the rotating component 110 may rotate; in another embodiment, the first working component 120 may rotate, and the rotating component 110 may not rotate.

[0055] Similarly, the second working assembly 121 is located on the side of each workpiece 200 away from its corresponding carrier 111. It can be understood that one end of any battery cell on which the rotating device 100 is installed can be supported and connected by the carrier 111, and the other end can be directly opposite to the second working assembly 121, so that the second working assembly 121 can process any battery cell. The second working assembly 121 is configured to be able to move along a second path around the rotation axis L. In some embodiments, the rotating assembly 110 and the second working assembly 121 may not be connected to each other, and the two may be connected to different driving mechanisms respectively. In other embodiments, the rotating assembly 110 and the second working assembly 121 may be connected to each other so that both can rotate around the rotation axis L at the same time.

[0056] like Figure 3 As shown, the first path and the second path are symmetrical to each other on the first plane. Specifically, the first path and the second path form a circle. It can be understood that the first working component 120 and the second working component 121 can be partially rotated on the rotating component 110, so that the first path and the second path can form an arc shape.

[0057] like Figure 5 and Figure 6 As shown, the second working assembly 121 has a third state and a fourth state. When the second working assembly 121 is in the third state, the second working assembly 121 is located at the P3 position, and the working assembly 120 is configured to rotate synchronously with the rotating assembly 110 to weld the workpiece 200. When the second working assembly 121 is in the fourth state, the second working assembly 121 is located at the P4 position, and the second working assembly 121 is configured to rotate displacedly relative to the rotating assembly 110 to adjust the position of the second working assembly 121 relative to the rotating assembly 110 so that the first working part 1201 is suitable for starting welding. It should be noted that the displaced rotation of the second working assembly 121 relative to the rotating assembly 110 is represented by the different angular velocities of the two (which can be different in magnitude or different in direction), and the synchronous rotation is represented by the same angular velocities of the two. Thus, it can be understood that, on the one hand, the second working component 121 can rotate synchronously with the rotating component 110, and during this process, the second working component 121 continues to be in a position suitable for welding the workpiece 200 (at this time, the second working component 121 can be suitable for welding one workpiece 200, and can also be suitable for welding multiple workpieces 200 at the same time), that is, the third state can be a state corresponding to the process of the second working component 121 welding the workpiece 200; on the other hand, the second working component 121 can also rotate relative to the rotating component 110, and the second state corresponds to the process of the second working component 121 being driven to the position ready for the next welding operation after one welding is completed.

[0058] It should be noted that the staggered rotation of the second working component 121 and the rotating component 110 means that during this process, the two are in a relative rotation relationship. Therefore, when the second working component 121 is in the fourth state, relative to the ground, in another embodiment, the second working component 121 and the rotating component 110 can both rotate, and the rotation speeds of the two are different; in another embodiment, the second working component 121 may not rotate, and the rotating component 110 may rotate; in another embodiment, the second working component 121 may rotate, and the rotating component 110 may not rotate.

[0059] It should be noted that the first working assembly 120 and the second working assembly 121 are arranged relative to each other, so as to achieve the balance of the first working assembly 120 and the second working assembly 121 on the rotating assembly 110. In other implementations, three working assemblies, four working assemblies, five working assemblies, etc. can be arranged on one rotating assembly, and the corresponding multiple working assemblies on the rotating assembly can be arranged in a balanced manner, so as to achieve the distinction of more than two workstations.

[0060] like Figure 1 and Figure 2 As shown, the rotating device 100 may further include a shaft 130. The rotating assembly 110 is configured to be rotatable relative to the shaft 130, and the central axis of the shaft 130 coincides with the rotation axis L. It is understandable that the rotating assembly 110 may be provided with an opening, the shaft 130 may be inserted into the opening, and the shaft 130 may be spaced apart from the rotating assembly 110 so that the rotating assembly 110 can rotate independently. In some embodiments, the first working assembly 120 and the second working assembly 121 extend radially along the rotation axis L, respectively. Along the radial direction of the rotation axis L, one end of the first working assembly 120 is connected to the shaft 130, and the other end is provided with a first working portion 1201, and one end of the second working assembly 121 is connected to the shaft 130, and the other end is provided with a second working portion 1211.

[0061] It can be understood that the shaft 130 can be used to connect and support the first working assembly 120 and the second working assembly 121, and along the radial direction of the rotation axis L, the first working assembly 120 and the second working assembly 121 can extend to a position suitable for processing the workpiece 200. Figure 3-Figure 5 In some embodiments, the first working assembly 120 and the second working assembly 121 may extend above the workpiece 200, and the first working assembly 120 and the second working assembly 121 may be directly opposite to the workpiece 200, that is, the first working assembly 120 and the second working assembly 121 may be substantially coaxial with the workpiece 200. By disposing the shaft 130 and the first working assembly 120 and the second working assembly 121, the radial extension distance of the first working assembly 120 and the second working assembly 121 may be adjusted according to processing requirements, so as to facilitate processing of the workpiece.

[0062] In order to make the first working assembly 120 and the second working assembly 121 in different states, the rotation state can be changed accordingly, such as Figure 1 and Figure 2, the rotating device 100 may further include a driving assembly 140. Thus, the driving assembly 140 may be configured to drive the first working assembly 120 and the second working assembly 121 to rotate around the rotation axis L. It is understandable that, through the different driving forms of the driving assembly 140 for the first working assembly 120 and the second working assembly 121, the driving assembly 140 can control the first working assembly 120 to switch between the first state and the second state, and the second working assembly 121 to switch between the third state and the fourth state. Specifically, in order to improve the accuracy, the driving assembly 140 drives the first working assembly 120 to switch from the second state to the first state, and the second working assembly 121 to switch from the fourth state to the third state. Specifically, in some embodiments, the driving assembly 140 may include a motor, a motor (DD motor may be used to ensure high-precision transmission), a screw, a hydraulic lever, a cylinder, etc. The preferred driving assembly 140 selects a DD motor. When the driving assembly 140 is a DD motor, the outer ring of the DD motor is fixed to the rotating assembly 110 , and the inner ring of the DD motor is fixed to the first working assembly 120 and the second working assembly 121 . The rotation of the inner ring of the DD motor realizes the rotation of the first working assembly 120 and the second working assembly 121 .

[0063] In order to achieve the accuracy of the welding process and reduce the vibration of the rotating component 110, the galvanometer is installed on the first working component 120 and the second working component 121. The first working component 120 and the second working component 121 are driven by a DD motor, and the DD motor is installed on the rotating shaft of the rotating component 110. During the welding process, the DD motor does not work, and the galvanometer rotates with the rotating shaft. The galvanometer is always located directly above the battery cell. After the battery cell welding of the current station is completed, the DD motor drives the galvanometer to reset, and then repeats the above process. This process can improve accuracy and reduce control difficulty.

[0064] In order to make the first working component 120 and the second working component 121 have higher working efficiency, as Figure 2 As shown, the first working assembly 120 may be provided with a plurality of first working parts 1201, and the second working assembly 121 may be provided with a plurality of second working parts 1211. Each first working part 1201 and each second working part 1211 are arranged in a one-to-one correspondence.

[0065] It can be understood that the above configuration enables the first working component 120 to be in the first state and the second working component 121 to be in the third state, so that operations such as processing and cleaning can be performed on multiple workpieces 200 at the same time.

[0066] After one welding is completed, in order to enable the rotating device 100 to switch to the second state and return to the first position in time, in some embodiments, the rotating device 100 may further include a timer, and the timer may have a set time.

[0067] In order to realize automatic loading and unloading of the workpiece 200, the rotating device 100 also includes a first conveyor line 150 and a second conveyor line 160. The first conveyor line 150 can load and unload the workpiece 200 of the first working component 120, and the second conveyor line 160 can load and unload the workpiece 200 of the second working component 121. In order to facilitate the control of the conveying angle of the workpiece 200, the loading lines of the first conveyor line 150 and the second conveyor line 160 are provided with a spiral feeding mechanism. A first post-weld detection device 170 is provided on the first conveyor line 150, and a second post-weld detection device 171 is provided on the second conveyor line 160. The quality of the battery core after welding is detected by the first post-weld detection device 170 and the second post-weld detection device 171 to ensure the welding quality of the workpiece of the entire welding device.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
