Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0033] See also Figures 1 to 3 An embodiment of the present application provides a flipping device 100, which can be used to flip the battery module 200 to facilitate operations on the back side of the battery module 200, such as inspecting the back side of the battery module 200, attaching a thermal conductive film, etc.

[0034] The turning device 100 includes a base 110 , a rotating frame 120 and a clamping mechanism 125 .

[0035] The base 110 is used to support the rotating frame 120 , the clamping mechanism 125 , the battery module 200 and other structural components.

[0036] The rotating frame 120 is rotatably connected to the base 110. The rotating frame 120 includes a support portion 1222 for placing the battery module 200. The support portion 1222 is provided with an operating window 1221. When the rotating frame 120 rotates, it can drive the battery module 200 to rotate synchronously, so as to conveniently flip the battery module 200 and facilitate operations on the back of the battery module 200 through the operating window 1221.

[0037] For example, the work window 1221 can extend through the rotating frame 120 and face the back of the battery module 200. The rotating frame 120 can rotate from 0 to 180 degrees. After the rotating frame 120 rotates 180 degrees, the battery module 200 can be flipped over to expose the back of the battery module 200, facilitating work on the back of the battery module 200 through the work window 1221. It is understood that the rotating frame 120 can also rotate to other angles, and the specific design can be based on needs.

[0038] The shape of the operation window 1221 can be designed according to needs. For example, the operation window 1221 can be a circular window, an elliptical window, a polygonal window or a window of other shapes.

[0039] The size of the operating window 1221 can be designed according to needs to adapt to battery modules 200 of different sizes.

[0040] The clamping mechanism 125 is connected to the rotating frame 120 and is used to clamp the battery module 200, helping to prevent the battery module 200 from falling during flipping. In addition, the clamping mechanism 125 can clamp battery modules 200 of different sizes, helping the flipping device 100 adapt to different types of battery modules 200 and expanding the compatibility of the flipping device 100. The clamping mechanism 125 can also release the battery module 200 to replace the battery module 200 and perform operations on different battery modules 200.

[0041] In some embodiments, the clamping mechanism 125 includes two clamping assemblies 130 disposed opposite to each other. In some embodiments, at least one of the two clamping assemblies 130 is movably connected to the rotating frame 120, and the two clamping assemblies 130 move toward each other to clamp the battery module 200 on opposite sides (e.g., Figure 3 As shown), to clamp the battery module; the two clamping components 130 move back to release the battery module 200 (as Figure 2 As the clamping assemblies 130 move, they can increase or decrease the distance between the two clamping assemblies 130 to accommodate battery modules 200 of different sizes, expanding the compatibility of the flip device 100. The simple method of clamping the battery module 200 by the clamping assemblies 130 helps simplify the operation process, reduce the difficulty of securing the battery module 200, and shorten the time required to secure the battery module 200.

[0042] The two clamping assemblies 130 moving toward each other may refer to one clamping assembly 130 moving toward the other clamping assembly 130, or may refer to both clamping assemblies 130 moving toward the other clamping assembly 130. Similarly, the two clamping assemblies 130 moving away from each other may refer to one clamping assembly 130 moving away from the other clamping assembly 130, or may refer to both clamping assemblies 130 moving toward the other clamping assembly 130.

[0043] During the actual production process, a hoist is used to lift the battery module 200 into the installation space 140 on the flipping device 100, and then the clamping assembly 130 is moved to clamp the battery module 200. Then, the rotating frame 120 is flipped to flip the battery module 200 and perform operations on the back of the battery module 200.

[0044] In some embodiments, an installation space 140 for placing the battery module 200 is formed between the two clamping assemblies 130. When the clamping assemblies 130 are moved, the size of the installation space 140 can be changed to accommodate battery modules 200 of different sizes. The installation space 140 can be opposite to and connected to the operation window 1221.

[0045] In some embodiments, the clamping assembly 130 includes a clamping member 131 and a mounting base 132 connected at an angle, and the mounting base 132 is movably connected to the rotating frame 120 .

[0046] Among them, the mounting seat 132 is movably connected to the rotating frame 120. It can be that among the two clamping components 130, the mounting seat 132 of one clamping component 130 is movably mounted on the rotating frame 120; or it can be that among the two clamping components 130, the mounting seat 132 of each clamping component 130 is movably connected to the rotating frame 120.

[0047] In some embodiments, the clamping assembly 130 clamps the battery module 200 via the clamping member 131 , thereby expanding the contact area between the clamping assembly 130 and the battery module 200 , and helping the clamping assembly 130 to clamp the battery module 200 more stably.

[0048] In some embodiments, the clamping assembly 130 is detachably connected to the rotating frame 120. Clamping assemblies 130 of different sizes can be replaced according to different processing requirements to accommodate battery modules 200 of different sizes, further expanding the compatibility of the flipping device 100. The clamping assembly 130 can be detachably connected to the rotating frame 120 via a fixing member, which can be a bolt, screw, rivet, or other fixed structural member. Alternatively, the clamping assembly 130 can be detachably connected to the rotating frame 120 by other means.

[0049] Furthermore, the clamping member 131 is detachably connected to the mounting base 132 , so that the battery modules 200 of different sizes can be adapted by simply replacing the clamping member 131 without replacing the entire clamping assembly 130 , thereby reducing the production cost of the clamping assembly 130 .

[0050] The clamping member 131 can be detachably connected to the mounting seat 132 via a fixing member, which can be a bolt, a screw, a rivet or other fixed structural member, or the clamping member 131 can be detachably connected to the mounting seat 132 in other ways.

[0051] In some embodiments, the battery module 200 has a positioning hole 210, and the clamping assembly 130 is provided with a positioning member 133 for being inserted into the positioning hole 210. The positioning hole 210 and the positioning member 133 correspond one to one. The two clamping assemblies 130 move toward each other so that the positioning member 133 is inserted into the positioning hole 210 to position the battery module 200. After positioning, the battery module 200 can be prevented from deflecting, so that the clamping assembly 130 can clamp the battery module 200 more stably, reducing the situation where the battery module 200 falls when flipped due to the clamping assembly 130 clamping the battery module 200.

[0052] The number of the positioning members 133 may be one or more, and “more than” may mean “two” or “more than two”.

[0053] As an example, when there are multiple positioning members 133, taking the example of two positioning members 133 connected to each clamping member 131, two positioning holes 210 are provided on opposite sides of the battery module 200. When the clamping assembly 130 clamps the battery module 200, the two positioning members 133 on one clamping assembly 130 are respectively inserted into the two positioning holes 210 on one side of the battery module 200, and the two positioning members 133 on the other clamping assembly 130 are respectively inserted into the two positioning holes 210 on the other side of the battery module 200. In this way, the two positioning members 133 can more accurately position the battery module 200. In this example, the positioning members 133 can adopt a cylindrical structure to facilitate processing. For example, the positioning members 133 can adopt positioning pins.

[0054] As another example, when each clamping assembly 130 is provided with a positioning member 133, the positioning member 133 can be designed to be prismatic, semi-cylindrical, or polygonal cylindrical. Correspondingly, the shape of the positioning hole 210 can be adapted to the shape of the positioning member 133 to better position the battery module 200 and reduce the deflection of the battery module 200.

[0055] In addition, when workers use a hoist to hoist the battery module 200 , they can also hoist the battery module 200 through the positioning holes 210 .

[0056] In some embodiments, the clamping member 131 includes a clamping portion 1311 and a limiting portion 1312 connected to each other. The clamping portion 1311 is connected to the mounting seat 132 , and the limiting portion 1312 and the clamping portion 1311 are arranged at an angle.

[0057] The clamping portion 1311 is used to abut against the side surface of the battery module 200 . The clamping portions 1311 of the two clamping assemblies 130 can clamp the battery module 200 from two opposite side surfaces of the battery module 200 .

[0058] The limiting portion 1312 is used to abut against the top side of the battery module 200 , so that when the rotating frame 120 rotates, the battery module 200 can abut against the limiting portion 1312 , and the limiting portion 1312 can support the battery module 200 to prevent the battery module 200 from falling.

[0059] As an example, the limiting portion 1312 is connected to the end of the clamping portion 1311 away from the mounting seat 132 and extends toward the side of the mounting space 140. Both ends of the battery module 200 are provided with stepped surfaces, and the limiting portion 1312 is used to abut against the stepped surfaces to limit the battery module 200.

[0060] In addition, since the clamping assembly 130 is detachably mounted on the rotating frame 120, or the clamping member 131 is detachably connected to the mounting base 132, and the positioning member 133 is connected to the clamping member 131, when replacing a different battery module 200, a different clamping assembly 130 or clamping member 131 can be replaced so that the positioning member 133 on the clamping assembly 130 can adapt to the positioning holes 210 of battery modules 200 of different sizes, which helps the flipping device 100 to better adapt to different types of battery modules 200.

[0061] In some embodiments, the clamping assembly 130 includes a first sliding member 134, and the rotating frame 120 is provided with a second sliding member 121 that cooperates with the first sliding member 134. One of the first sliding member 134 and the second sliding member 121 is a slider, and the other is provided with a sliding groove that cooperates with the slider, so that the clamping assembly 130 can move on the rotating frame 120.

[0062] It can be understood that at least one of the two clamping assemblies 130 includes a first sliding member 134 .

[0063] The second sliding member 121 is detachably connected to the rotating frame 120. By replacing the second sliding member 121 of different sizes, the moving stroke of the clamping assembly 130 can be changed, thereby changing the size of the installation space 140 to adapt to battery modules 200 of different sizes, further expanding the compatibility of the flip device 100.

[0064] The second sliding member 121 can be detachably connected to the rotating frame 120 via a fixing member, which can be a bolt, a screw, a rivet or other fixed structural member, or the second sliding member 121 can be detachably connected to the rotating frame 120 in other ways.

[0065] When the second sliding member 121 is a slider, second sliding members 121 of different sizes may refer to sliders of different lengths; when the second sliding member 121 is a chute, second sliding members 121 of different sizes may refer to chute grooves of different lengths.

[0066] In some embodiments, the rotating frame 120 includes a rotating member 122 , a first limiting member 123 , and a second limiting member 124 .

[0067] The rotating member 122 is rotatably connected to the base 110 , and the clamping mechanism 125 is connected to the rotating member 122 .

[0068] The first limiting member 123 and the second limiting member 124 are respectively connected to the left and right sides of the rotating member 122 along the rotation axis direction (such as Figure 2 As shown in FIG, the support portion 1222 is located between the first limit member 123 and the second limit member 124. The first limit member 123, the second limit member 124 and the two clamping assemblies 130 together form an installation space 140. The first limit member 123 and the second limit member 124 can abut against the left and right sides of the battery module 200 to reduce the movement of the battery module 200 to the sides, so that the battery module 200 can be placed more stably in the installation space 140.

[0069] In some embodiments, at least one of the first limiting member 123 and the second limiting member 124 is detachably connected to the rotating member 122 to adapt to battery modules 200 of different sizes.

[0070] Among them, the first limit member 123 and the second limit member 124 can be detachably connected to the rotating member 122 through a fixing member, and the fixing member can be a bolt, a screw, a rivet or other fixed structural member, or the first limit member 123 and the second limit member 124 can also be detachably connected to the rotating member 122 through other means.

[0071] In some embodiments, the flipping device 100 further includes a first driving device 150 , which is used to drive the clamping mechanism 125 to move so as to clamp or release the battery module 200 , thereby eliminating the need for manual operation of the clamping mechanism 125 .

[0072] Specifically, the first driving device 150 is used to drive the clamping assembly 130 to move back and forth to clamp or release the battery module 200 .

[0073] The first drive device 150 may be a linear drive device, and a driving end of the first drive device 150 is connected to the clamping assembly 130 to drive the clamping assembly 130 to move back and forth. For example, the first drive device 150 may be a lifting cylinder or other linear drive devices.

[0074] It can be understood that a transmission structure can also be set between the first drive device 150 and the clamping assembly 130, and the transmission structure is used to convert the rotational motion of the first drive device 150 into linear motion to drive the clamping assembly 130 to move back and forth. For example, the first drive device 150 can adopt a motor, a rotary cylinder or other rotary drive device.

[0075] In some embodiments, the first driving device 150 has a locking function to facilitate locking the clamping assembly 130 at a desired position.

[0076] In some embodiments, the turning device 100 includes a second driving device 160 , which is connected to the base 110 . The second driving device 160 is used to drive the rotating frame 120 to rotate, eliminating the need for manual turning of the rotating frame 120 .

[0077] The second driving device 160 is a rotation driving device, and a driving end of the second driving device 160 is connected to the rotating frame 120 to drive the rotating frame 120 to rotate. For example, the second driving device 160 can be a motor, a rotary cylinder, or other rotation driving devices.

[0078] It can be understood that a transmission structure can also be set between the second drive device 160 and the rotating frame 120, and the transmission structure is used to convert the linear motion of the first drive device 150 into rotational motion to drive the rotating frame 120 to move back and forth. For example, the first drive device 150 can adopt a lifting cylinder or other linear drive device.

[0079] See also Figure 4 In some embodiments, the second drive device 160 may include a drive member 161, a rack 162, and a gear 163. The drive member 161 is connected to the base 110, the rack 162 is movably connected to the base 110, and the gear 163 is connected to the turret 120. The driving end of the drive member 161 is connected to the rack 162 to drive the rack 162 to move back and forth. The rack 162 and the gear 163 are engaged, and the back-and-forth movement of the rack 162 drives the gear 163 to rotate, thereby driving the turret 120 to rotate. In this way, the rack 162 and the gear 163 cooperate to convert the linear motion of the drive member 161 into rotational motion, thereby driving the turret 120 to rotate. Furthermore, the cooperation between the rack 162 and the gear 163 can better control the rotation angle of the turret 120.

[0080] Among them, the rack 162 is movably connected to the base 110. For example, a slider can be provided on the rack 162, and a sliding groove that cooperates with the slider can be provided on the base 110 to facilitate the back and forth movement of the rack 162; or, a sliding groove can be provided on the rack 162, and a slider that cooperates with the sliding groove can be provided on the base 110; or, the rack 162 can also be movably connected to the base 110 in other ways.

[0081] The driving member 161 can be driven to rotate in a linear manner, for example, the driving member 161 can be a lifting cylinder.

[0082] In some embodiments, the second driving device 160 may have a locking function to lock the rotating frame 120 at a desired position. Specifically, the driving member 161 has a locking function to lock the rotating frame 120 at a desired position.

[0083] See also Figure 1 In some embodiments, the flipping device 100 may include multiple flipping components, each of which is composed of a rotating frame 120 and a clamping mechanism 125, so that the flipping device 100 can flip multiple battery modules 200 at the same time, which helps to speed up production.

[0084] In the flipping device 100 provided in the embodiment of the present application, the rotating frame 120 is rotatably connected to the base 110, and the rotating frame 120 includes a support portion 1222 for placing the battery module 200, and the support portion 1222 is provided with an operating window 1221. The clamping mechanism 125 is connected to the rotating frame 120, and the clamping mechanism 125 can clamp the battery module 200. When the rotating frame 120 rotates, it can drive the battery module 200 to rotate synchronously to prevent the battery module 200 from falling during flipping, so that the battery module 200 can be flipped conveniently and stably, making it convenient to operate on the back of the battery module 200 through the operating window 1221.
