Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of battery manufacturing equipment, in particular to a battery cell rotating device. BACKGROUND

[0002] With the continuous progress of power battery technology and the growing market demand, the performance of batteries in new energy battery vehicles is increasingly concerned, and the energy density and safety of the battery become important indicators for measuring battery performance. The battery cell rotating device is commonly used in battery assembly, detection, testing and other links on the battery production line.

[0003] The existing battery cell rotating device usually adopts a clamping method, such as side clamping and top clamping. Side clamping is to apply clamping force to the side of both ends of the battery cell, and then perform a turnover operation. In the turnover process, the battery cell acts as a connecting piece that bears torque. When the rotation speed of the two ends of the rotating mechanism is different, the battery cell will deform, and the surface of the clamping jaw that clamps the battery cell is prone to wear and failure, which will cause the clamping force to decrease and the battery cell to fall off. Top clamping usually applies clamping force to the two ends of the battery cell, and then performs a turnover operation. The battery cell also bears torque, which is prone to cause the battery cell to deform, and the top pole is prone to cause the pole to deform and be dirty, thereby adversely affecting the welding. Content of the utility model

[0004] The embodiment of the present application provides a battery cell rotating device, which connects the driving mechanism and the driven mechanism at both ends through a transmission connecting piece to ensure the synchronization of the driving mechanism and the driven mechanism at both ends, uses the transmission connecting piece to bear torque, and the pole and the cover plate of the battery cell do not directly bear clamping force, thereby ensuring the integrity of the battery cell and improving the overall product quality of the battery cell.

[0005] The embodiment of the present application provides the following technical solutions to solve the above technical problems:

[0056] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of 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.

[0057] The embodiment of the present application provides a battery core rotating device, such as Figure 1 As shown, it includes a base 100, an active mechanism 200, a driven mechanism 300, a transmission connector 400 and a driving mechanism 500. The base 100 has a first end and a second end. The active mechanism 200 is located at the first end of the base 100 and is rotatably arranged on the base 100. The active mechanism 200 is used to support one end of the battery cell. The driven mechanism 300 is located at the second end of the base 100 and is rotatably arranged on the base 100. The driven mechanism 300 is used to support the other end of the battery cell. The two ends of the transmission connector 400 are respectively connected to the active mechanism 200 and the driven mechanism 300. One end of the driving mechanism 500 is connected to the active mechanism 200. The driving mechanism 500 is used to drive the active mechanism 200 to rotate, thereby driving the transmission connector 400 to rotate and driving the driven mechanism 300 to rotate, so that the battery cells located on the active mechanism 200 and the driven mechanism 300 rotate.

[0058] The base 100 is the supporting foundation of the battery cell rotation device. The base 100 is used to install the active mechanism 200, the driven mechanism 300, and the driving mechanism 500, and ensure that the active mechanism 200 and the driven mechanism 300 maintain a stable relative position during the entire rotation process on the base 100. The active mechanism 200 is located at the first end of the base 100 and is rotatably arranged on the base 100. The active mechanism 200 is used to support one end of the battery cell. The driven mechanism 300 is located at the second end of the base 100 and is arranged opposite to the active mechanism 200. The driven mechanism 300 is used to support the other end of the battery cell. The two ends of the battery cell are respectively located on the active mechanism 200 and the driven mechanism 300. During the rotation process, the battery cell will not fall off or shift due to the constraints of the active mechanism 200 and the driven mechanism 300.

[0059] The driving mechanism 500 is connected to the active mechanism 200. The driving mechanism 500 is the power source for the rotation of the active mechanism 200. The active mechanism 200 is driven to rotate on the base 100 by the driving mechanism 500. The driven mechanism 300 is connected to the active mechanism 200 by a transmission connector 400. When the driving mechanism 500 drives the active mechanism 200 to rotate, the driving force is transmitted through the transmission connector 400 to drive the driven mechanism 300 to rotate synchronously with the active mechanism 200. This ensures the synchronous rotation of the active mechanism 200 and the driven mechanism 300 under the same power source, avoiding the deformation of the battery cell caused by the asynchronous rotation of the two mechanisms at both ends of the battery cell driven by two power sources in the related art. Therefore, the driven mechanism 300 is driven to rotate through the transmission connector 400, achieving the synchronous rotation of the active mechanism 200 and the driven mechanism 300, ensuring that the battery cells carried by the active mechanism 200 and the driven mechanism 300 are not easily deformed during rotation.

[0060] It can be understood that the two ends of the transmission connector 400 are respectively connected to the active mechanism 200 and the driven mechanism 300. During the process of the driving mechanism 500 driving the rotation, the battery cell does not bear torque, but transmits the rotational force and bears torque through the transmission connector 400, thereby reducing the possibility of deformation of the battery cell. It should be noted that the transmission connector 400 has high strength and high wear resistance to ensure long-term stable operation. Rigid connectors such as high-strength alloy steel, stainless steel or special engineering plastics can be used to ensure sufficient load-bearing capacity. There is no restriction on the size and material of the transmission connector 400, and it can be adaptively adjusted according to the needs of actual working conditions.

[0061] In the examples of the present application, one driving mechanism 200 corresponds to one driven mechanism 300, one driving mechanism 200 and one driven mechanism 300 are connected through a transmission connecting piece 400, the driving mechanism 500 drives the driving mechanism 200 to rotate, and drives the driven mechanism 300 to rotate through the transmission connecting piece 400. But it is not limited to one transmission connecting piece 400, for example, it can also be two transmission connecting pieces 400, the two transmission connecting pieces 400 are oppositely arranged and connected with the driving mechanism 200 and the driven mechanism 300 respectively, so as to improve the bearing torque and ensure that the battery cell does not easily deform during rotation.

[0062] In some embodiments of the present application, the number of driving mechanisms 200 is multiple, the number of driven mechanisms 300 is multiple, and the number of driving mechanisms 200 is equal to the number of driven mechanisms 300. As shown in Figure 1 It can be understood that one driving mechanism 200 and one driven mechanism 300 can realize the rotation of one battery cell. Figure 1 The battery cell rotating device shown in the figure can simultaneously satisfy the rotation of two battery cells on the base.

[0063] It should be noted that the number of driving mechanisms 200 and driven mechanisms 300 is not limited to two as shown in the figure, and can be any number, which can be adjusted according to the actual working condition and the number of battery cells required to rotate, which is not limited here.

[0064] In some embodiments of the present application, as shown in Figures 1 to 3 The battery cell rotating device further comprises at least one limiting structure 600, one limiting structure 600 is connected with the driving mechanism 200, and the limiting structure 600 is used for limiting one end of the battery cell.

[0065] The limiting structure 600 can limit the movement range of the battery cell during rotation, so as to ensure that one end of the battery cell is limited to a certain position. As shown in Figure 2 In the embodiments of the present application, one battery cell is limited by two limiting structures 600, which are located at both ends of the battery cell. One limiting structure 600 is connected with the driving mechanism 200, and the other limiting structure is connected with the driven mechanism 300. The two limiting structures 600 can enhance the limitation of the battery cell from deviating or falling off during rotation when the driving mechanism 500 drives to rotate.

[0066] In some embodiments of the present application, as shown in Figure 3 The limiting structure 600 comprises two oppositely arranged first limiting plates 610, at least one first limiting plate 610 is arranged along the length direction of the battery cell and can be extended and retracted, and the first limiting plate 610 is used for limiting the width direction of the battery cell, that is Figure 1 As shown in the figure, the movement in the Z direction is limited.

[0067] The two first limiting plates 610 arranged oppositely are respectively located at two sides of the battery cell, and limit the movement of the battery cell in the width direction. When the battery cell is clamped between the two first limiting plates 610, the degree of freedom of the battery cell in the width direction is limited, thereby ensuring the stability of the battery cell during rotation and avoiding the battery cell from falling off the limiting structure during rotation.

[0068] It can be understood that the first limiting plate 610 is retractable in the length direction of the battery cell, which is beneficial to loading the battery cell into the battery cell rotating device from top to bottom and simplifying the assembly operation process and reducing the possibility of deforming the battery cell due to improper operation. It should be noted that the distance between the two oppositely arranged first limiting plates 610 can be greater than or equal to the size of the battery in the width direction, which is not limited here.

[0069] In some embodiments of the present application, please continue to refer to Figure 3 The limiting structure 600 includes a pushing block 620 and a driving member 630. One end of the pushing block 620 is connected with the first limiting plate 610, and the other end of the pushing block 620 is connected with the driving member 630. The driving member 630 pulls the pushing block 620 to make the first limiting plate 610 retractable and movable.

[0070] It can be understood that the driving member 630 pulls the first limiting plate 610 away from the base 100 in advance, so that the battery cell is loaded into the limiting structure 600 from top to bottom. When the bottom of the battery cell contacts the first limiting plate 610 close to the base 100, the pulling force of the driving member 630 is removed, the first limiting plate 610 away from the base 100 is reset, and the battery cell is limited between the two first limiting plates 610.

[0071] It should be noted that the driving member 630 generates a pulling force, and the first limiting plate 610 is fixed at one end of the pushing block 620. The driving member 630 pulls the pushing block 620 to drive the first limiting plate 610 to retractably and movably move in the length direction of the battery cell. The driving member 630 can adopt a motor or a pneumatic cylinder or a spring or other types of drivers, which are not limited herein as long as the driving member 630 can pull the pushing block 620 to drive the first limiting plate 610 to retractably and movably move.

[0072] In the example of the present application, two push blocks 620 are arranged on one limiting structure 600 to realize the extension and retraction control of two oppositely arranged first limiting plates 610 respectively. The push block 620 away from the base 100 is pulled by the driving member 630 to drive the first limiting plate 610 at the top to retract, and then the battery cell is inserted into the limiting structure 600 from top to bottom. One end of the battery cell is limited between the first limiting plate 610 at the bottom and the two second limiting plates 660. When the pulling force of the driving member 630 is removed, the first limiting plate 610 at the top is reset. At this time, the battery cell is limited between the two first limiting plates 610 and the two second limiting plates 660. The driving mechanism 500 provides a rotating force to rotate the battery cell by 180°. The first limiting plate 610 at the top after rotation is pulled by the driving member 630 to take out the battery cell after rotation from the top, and the battery cell is completed once.

[0073] As shown in some embodiments of the present application, Figure 3 The limiting structure 600 includes a push rod 640 and a mounting plate 650. The push rod 640 is located at one end of the mounting plate 650, and the push rod 640 is connected with the push block 620. The other end of the mounting plate 650 is connected with the driving member 630. The push block 620 is provided with a clamping groove 621 located at one end away from the first limiting plate 610. The push block 620 is connected with the driving member 630 through the clamping groove 621. The driving member 630 pulls the push rod 640 to make the first limiting plate 610 at one end of the push block 620 moveable.

[0074] In the example of the present application, the number of push rods 640 on each limiting structure 600 is two. The push rod 640 is fixed on the mounting plate 650, and the push rod 640 cooperates with the clamping groove 621 on the push block 620. The driving member 630 pulls the mounting plate 650 to drive the movement of the push block 620, thereby realizing the extension and retraction of the first limiting plate 610. It should be noted that the push rod 640 and the push block 620 have sufficient rigidity and stability to withstand the pulling force provided by the driving member 630 to realize the movement of the first limiting plate 610. It should be noted that the clamping groove 621 on the push block 620 can be rectangular, circular or elliptical. The clamping groove 621 is used to connect the push block 620 and the push rod 640. The shape and size of the clamping groove 621 and the push rod 640 are not limited here, and they can meet the connection requirements.

[0075] The mounting plate 650 has a large end and a small end, wherein two levers 640 are symmetrically provided on the large end of the mounting plate 650, and the small end of the mounting plate 650 is connected to the driving member 630. When the driving member 630 pulls the mounting plate 650, the two first limit plates 610 at the top can be retracted at the same time, thereby simultaneously satisfying the installation of the two battery cells or the removal of the battery cells after rotation. The symmetrical levers 640 can evenly distribute the pulling force provided by the driving member 630 to ensure that the two lever blocks 620 can move synchronously. It should be noted that, but not limited to, the above-mentioned setting, for example, any number of levers 640 can be provided on the mounting plate 650 to achieve the telescopic movement of any number of first limit plates 610.

[0076] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the limiting structure 600 further includes two second limiting plates 660 that are oppositely arranged. The second limiting plates 660 are perpendicular to the first limiting plates 610 and are used to limit the thickness direction of the battery cell.

[0077] The second limiting plate 660 is perpendicular to the first phase plate, that is, the two oppositely arranged first limiting plates 610 limit the movement of the battery cell in the width direction, and the two oppositely arranged second limiting plates 660 limit the movement of the battery cell in the thickness direction, that is, Figure 1 The movement in the Y direction is limited as shown. The multi-dimensional movement restriction formed by the first limiting plate 610 and the second limiting plate 660 can better ensure the stability of the battery cell during the rotation and prevent it from falling from the limiting structure.

[0078] It is understandable that there are two first limiting plates 610 and two second limiting plates 660 on the single-sided limiting structure 600, and they are arranged opposite to each other, ensuring the balance of the limiting effect and preventing the battery cell from falling off the limiting structure 600 during the rotation process. When the driving member 630 pre-pushes the first limiting plate 610 facing away from the base 100, so that the battery cell is loaded into the limiting structure 600 from top to bottom, the bottom of the battery cell contacts the first limiting plate 610 close to the base 100, and the two sides of the battery cell are restricted between the two second limiting plates 660. The pulling force of the driving member 630 is removed, and the first limiting plate 610 facing away from the base 100 is reset, and the battery cell is restricted between the two first limiting plates 610 and the two second limiting plates 660. It should be noted that the distance between the two oppositely arranged second limiting plates 660 can be greater than or equal to the dimension in the thickness direction of the battery, which is not limited here.

[0079] In some embodiments of the present application, Figure 1 and Figure 2As shown, the number of the limiting structures 600 is at least two, one of which is connected with the driving mechanism 200, and the other of which is connected with the driven mechanism 300. The battery cell rotating device of the embodiment of the application can limit and rotate two battery cells at the same time, that is, one battery cell is rotated by the driving mechanism 500, the driving mechanism 200, the transmission connecting piece 400, and the driven mechanism 300, and the number of each of them is one. The driving mechanism 200 and the driven mechanism 300 are each provided with a limiting structure 600, and the two ends of the battery cell can be connected with the driving mechanism 200 and the driven mechanism 300 respectively by the limiting structure 600, and the movement of the two ends of the battery cell is limited, so as to avoid the battery cell from falling when the driving mechanism 500 drives the driving mechanism 200 and the driven mechanism 300 to rotate.

[0080] As shown in FIGS. 1 to 3, the driving mechanism 500 is connected with the driving mechanism 200 through the transmission connecting piece 400, and the driven mechanism 300 is connected with the driving mechanism 500 through the transmission connecting piece 400. Figure 3 and Figure 4 As shown, the driving mechanism 200 and the driven mechanism 300 each include a first fixed plate 710, a second fixed plate 720, and a third fixed plate 730, the third fixed plate 730 is located between the first fixed plate 710 and the second fixed plate 720 and is movably arranged. One end of the knob 620 of the limiting structure 600 is connected with the third fixed plate 730.

[0081] The first fixed plate 710 and the second fixed plate 720 are fixed and supporting components, which provide stable support for the third fixed plate 730, and the third fixed plate 730 is movably arranged between the first fixed plate 710 and the second fixed plate 720 to realize the telescopic reset of the first limiting plate 610.
