In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] This embodiment provides a battery cell shell insertion device, which is used to push the battery cell 100 with the cover plate 400 into the battery shell 200 to complete the automatic shell insertion operation. In this embodiment, the battery cell 100 is a cylindrical battery cell as an example. Figure 1 As shown, the battery cell shelling device includes a deviation correction mechanism 10, a shelling mechanism 20 and a transfer mechanism 30. The deviation correction mechanism 10 and the shelling mechanism 20 are placed at intervals along the first direction, and the deviation correction mechanism 10 is located upstream of the shelling mechanism 20. The first direction is the X-axis direction in the figure, that is, the axial direction of the battery cell 100. The negative end of the battery cell 100 is connected to the cover plate 400 through the pole ear sheet 300. The deviation correction mechanism 10 is used to correct the battery cell 100 before shelling, so that the cover plate 400 and the pole ear sheet 300 on the battery cell 100 are located in the assembly position to meet the requirements of subsequent processes. The transfer mechanism 30 is used to transfer the corrected battery cell 100 from the deviation correction mechanism 10 to the shelling mechanism 20. The battery shell 200 is a cylindrical structure with an open end. The shelling mechanism 20 is used to push the end of the battery cell 100 without the cover plate 400 into the battery shell 200 from the open end of the battery shell 200 to complete the automatic shelling operation of the battery cell 100.

[0050] like Figure 2 As shown, the shell insertion mechanism 20 includes a supporting seat 21, a guide component 22, a fixing component 23 and a pushing component 24. The supporting seat 21 is provided with a guide groove 211 adapted to the shape of the battery cell 100, the guide component 22 is arranged on one side of the supporting seat 21 along the X-axis direction, and a guide hole 221 is provided on the guide component 22. The guide hole 221 is directly opposite to the guide groove 211 and is coaxially connected. The fixing component 23 is arranged on the side of the guide component 22 away from the supporting seat 21. The fixing component 23 is used to fix the battery shell 200 and push one end of the battery shell 200 into the guide hole 221; the pushing component 24 is arranged on the side of the supporting seat 21 away from the guide component 22, and the pushing component 24 is used to push the battery cell 100 into the battery shell 200 along the guide groove 211.

[0051] When the battery cell 100 is put into the shell, the transfer mechanism 30 first moves the battery cell 100 from the correction mechanism 10 to the guide groove 211 of the supporting seat 21. The guide groove 211 can guide and position the battery cell 100 to prevent the battery cell 100 from moving radially, thereby improving the accuracy of the battery cell 100. Since the guide hole 221 is coaxially connected with the guide groove 211, after the fixing component 23 pushes one end of the battery shell 200 into the guide hole 221, the guide hole 221 can guide and position the battery shell 200, so that the open end of the battery shell 200 is coaxially connected with the guide groove 211, and then the pushing component 24 pushes the battery cell 100 along the guide groove 211, so that the battery cell 100 passes through the guide hole 221 and accurately enters the battery shell 200. Through the two-stage guidance of the guide groove 211 and the guide hole 221, the guiding positioning accuracy is increased, the alignment accuracy of the battery cell 100 and the battery shell 200 is improved, and interference and collision between the battery cell 100 and the battery shell 200 during the shell insertion process are avoided, thereby improving the yield rate and production efficiency.

[0052] In an optional embodiment, if Figure 5 As shown, along the pushing direction of the battery cell 100, the guide hole 221 includes a first open section 2211, a guide section 2212, and a second open section 2213 connected in sequence, the guide section 2212 is adapted to the shape of the battery shell 200, and the connection between the first open section 2211, the guide section 2212, and the second open section 2213 is smoothly transitioned. The fixing component 23 pushes the battery shell 200 from the second open section 2213 into the guide section 2212, and the pushing component 24 pushes the battery cell 100 from the first open section 2211 into the battery shell 200 along the guide groove 211. The second open section 2213 is gradually expanded in the direction gradually approaching the battery shell 200, so that the battery shell 200 can be easily inserted into the guide hole 221. The guide section 2212 is adapted to the shape of the battery shell 200, and plays a guiding and positioning role for the battery shell 200, so that the battery shell 200 is coaxial with the guide groove 211, and the effect of the battery cell 100 entering the shell is avoided to be affected by the deviation of the axis of the battery shell 200 and the axis of the guide groove 211. The first open section 2211 is gradually expanded in the direction gradually approaching the guide groove 211, so that the battery cell 100 can easily enter the guide hole 221, and the battery cell 100 is avoided from being scratched and damaged. The smooth transition of the connection between the first open section 2211, the guide section 2212 and the second open section 2213 can also avoid the battery shell 200 and the battery cell 100 from being scratched when being pushed into the guide section 2212, thereby improving product quality and yield rate.

[0053] In an optional embodiment, if Figure 2 , Figure 4 and Figure 5As shown, the guide assembly 22 includes a support frame 226, an upper driving member 222, a lower driving member 223, an upper guide member 224 and a lower guide member 225. The upper driving member 222 and the lower driving member 223 are fixedly connected to the plate of the support frame 226 and are arranged relatively spaced apart in the vertical direction (Z-axis direction); the upper guide member 224 and the lower guide member 225 are arranged relatively in the vertical direction, and the upper guide member 224 and the lower guide member 225 are respectively provided with a half hole 2241 on the opposite side, and the two half holes 2241 are connected to form a closed guide hole 221, and the upper guide member 224 is connected to the output end of the upper driving member 222, and the lower guide member 225 is connected to the output end of the lower driving member 223. The upper driving member 222 can drive the upper guide member 224 to move in the vertical direction, and the lower driving member 223 can drive the lower guide member 225 to move in the vertical direction, so that the upper guide member 224 and the lower guide member 225 are close to each other, docked or separated. After the upper guide member 224 and the lower guide member 225 dock, the half hole 2241 of the upper guide member 224 and the half hole 2241 of the lower guide member 225 dock to form a closed guide hole 221. In this embodiment, the upper driving member 222 and the lower driving member 223 are cylinders. In other embodiments, the upper driving member 222 and the lower driving member 223 can also be other linear drive structures such as electric push rods, motor screw nuts, etc., which are not specifically limited here.

[0054] When in use, after the transfer mechanism 30 places the battery cell 100 on the guide groove 211 of the support seat 21, the upper driving member 222 drives the upper guide member 224 to descend, and at the same time the lower driving member 223 drives the lower guide member 225 to rise, so that the upper guide member 224 and the lower guide member 225 are connected to form a complete guide hole 221, and the guide hole 221 is coaxially connected with the guide groove 211, and then the fixing assembly 23 pushes one end of the battery shell 200 into the guide hole 221.

[0055] In an optional embodiment, if Figure 2 and Figure 4As shown, the pushing assembly 24 includes a support platform 244, a first movable module 241, a mounting frame 242 and a push rod 243. The first movable module 241 is fixed on the support platform 244, the mounting frame 242 is fixedly connected to the output end of the first movable module 241, and the push rod 243 is arranged on the mounting frame 242, wherein two mounting frames 242 are provided, and the two mounting frames 242 are spaced apart along the X-axis direction, and the two mounting frames 242 can respectively stably support the two end positions of the push rod 243, thereby ensuring the stability of the movement of the push rod 243; the push rod 243 is axially opposite to the battery cell 100, and the first movable module 241 drives the mounting frame 242 to move along the first direction, so that the mounting frame 242 drives the push rod 243 to move along the first direction, so that the push rod 243 pushes the battery cell 100 into the battery shell 200. It should be noted that, since the battery cell 100 on the supporting seat 21 is the battery cell 100 after deviation correction, during the pushing process, the cover plate 400 and the tab sheet 300 on the battery cell 100 are always in an upward horizontal position.

[0056] In the actual shell insertion operation, in order to prevent the cover plate 400 on the battery cell 100 from colliding with the upper guide member 224 and causing damage to the cover plate 400, in this embodiment, the first moving module 241 adopts a linear drive structure of a motor screw nut and a guide rail slider. The motor screw nut can preset the moving stroke of the output end. When the motor screw nut drives the push rod 243 to push the battery cell 100 along the first direction for the preset stroke, most of the battery cell 100 is pushed into the battery shell 200, and the cover plate 400 is about to reach the upper guide member 224. At this time, the motor stops moving, and then the upper drive member 222 drives the upper guide member 224 to rise to avoid the cover plate 400. The motor screw nut then drives the push rod 243 to push the battery cell 100 for a second time, so that the battery cell 100 is further pushed into the battery shell 200. This process enables the battery cell 100 with the cover plate 400 to smoothly enter the battery shell 200, avoids structural interference between the cover plate 400 and the upper guide member 224 that may cause damage to the cover plate 400, and realizes automatic shell entry of the battery cell 100 with the cover plate 400, thereby ensuring high-quality shell entry of the battery cell 100 while improving production efficiency, thereby improving production yield.

[0057] Combination Figure 2 and Figure 4, a plurality of push rods 243 are arranged on the mounting frame 242, and the plurality of push rods 243 are arranged at intervals along the second direction (Y-axis direction), a plurality of guide grooves 211 corresponding to the push rods 243 are arranged on the supporting seat 21, and each guide groove 211 can accommodate a battery cell 100, a plurality of guide holes 221 corresponding to the guide grooves 211 are arranged on the guide assembly 22, and a plurality of battery shells 200 corresponding to the guide holes 221 are fixed on the fixing assembly 23, and each push rod 243 is used to push the corresponding battery cell 100 into the corresponding battery shell 200. With this arrangement, the automatic shelling of multiple battery cells 100 can be completed at one time, thereby improving the production efficiency of the product. Among them, the specific number of the above-mentioned push rods 243, guide grooves 211 and guide holes 221 can be adaptively selected according to actual needs, and no specific limitation is made here.

[0058] Combination Figure 2 and Figure 3 The mounting frame 242 on the side facing away from the supporting seat 21 includes a base 2421 and a first mounting plate 2422 and a second mounting plate 2423 fixedly connected to the base 2421 along a first direction. The base 2421 is connected to the output end of the first movable module 241. The end of the push rod 243 facing away from the supporting seat 21 passes through the second mounting plate 2423 and is connected to the elastic member 246. A pressure sensor 247 is provided on the side of the first mounting plate 2422 close to the second mounting plate 2423, and the end of the elastic member 246 facing away from the push rod 243 abuts against the pressure sensor 247. When the push rod 243 pushes the battery cell 100 completely into the battery shell 200, the battery cell 100 reacts pressure on the push rod 243, and the push rod 243 applies pressure to the pressure sensor 247 through the elastic member 246. When the pressure sensor 247 senses that the pressure of entering the shell reaches the preset requirement, it means that the shell entry is completed. At this time, the first moving module 241 stops driving to avoid excessive pushing and causing damage to the battery cell 100. The elastic member 246 can play a buffering role, control the degree of pressure, and further avoid damage to the battery cell 100. Among them, the elastic member 246 is a spring.

[0059] like Figure 2 and Figure 3 As shown, a linear bearing 245 is fixedly connected to the first mounting plate 2422, and a linear bearing 245 is also fixedly connected to the mounting frame 242 near the supporting seat 21, and the push rod 243 is installed in the linear bearing 245. The linear bearing 245 can ensure the stability of the installation of the push rod 243 and the smoothness of the reverse movement of the push rod 243 when the shell is completed.

[0060] like Figure 3As shown, two opposite limit members 248 are provided on the flange plate of the linear bearing 245 on the first mounting plate 2422, and a limit protrusion 2431 is provided on the peripheral side of the push rod 243. The limit protrusion 2431 can abut against the surfaces of the two limit members 248 to play a limit role and prevent the push rod 243 from moving along the positive direction of the X-axis.

[0061] In an optional embodiment, if Figure 4 As shown, the shell entry mechanism 20 also includes a light pressing component 25, which is located on the upper side of the battery shell 200 and is used to lightly press the battery shell 200 located on the fixing component 23. Specifically, the light pressing component 25 includes a light pressing driver 251 and a light pressing plate 252 connected to the output end of the light pressing driver 251, and the light pressing driver 251 is fixed to the plate of the support frame 226, and the light pressing driver 251 can drive the light pressing plate 252 to move downward to lightly press the battery shell 200. In the process of the pushing component 24 pushing the battery cell 100 into the battery shell 200, the shape of the battery cell 100 may be wrinkled, which may cause the battery shell 200 to easily move upward. The light pressing plate 252 lightly presses on the battery shell 200 to prevent the battery shell 200 from moving upward, and can also play a role in pressing the battery shell 200 when the upper guide 224 moves upward to avoid the cover plate 400. The light pressure driving member 251 may be a cylinder or an electric push rod, etc., which is not specifically limited here.

[0062] In an optional embodiment, if Figure 4 As shown, the fixing assembly 23 includes a fixing frame 231, a driving component 232 and a fixing member 233, the driving component 232 is fixed on the fixing frame 231, the fixing member 233 is fixedly connected to the output end of the driving component 232, the battery shell 200 is fixed on the fixing member 233, the fixing frame 231 is fixed on a flow mechanism such as a turntable or a conveyor line, so as to move the battery shell 200 from the previous station to the battery cell shell entry station, and to move the battery shell 200 with the battery cell 100 after shell entry to the next station, and the driving component 232 can drive the fixing member 233 to move along the X-axis direction to push the empty battery shell 200 into the guide hole 221, or to move the battery shell 200 with the battery cell 100 after shell entry out of the guide hole 221. Among them, the fixing member 233 can fix the battery shell 200 by vacuum adsorption, clamping with a clamp, etc. In this embodiment, the driving component 232 is a linear driving structure of a cylinder and a guide rail slider. In other embodiments, the driving component 232 can also be other linear driving structures such as an electric push rod, a motor screw nut, etc., which are not specifically limited here.

[0063] In an optional embodiment, if Figures 6 to 8As shown, the correction mechanism 10 includes a detection component 11 and a rotation component 12. The battery cell shell insertion device also includes a control system. The detection component 11 and the rotation component 12 are electrically connected to the control system respectively. The detection component 11 is used to detect whether the cover plate 400 and the pole tab 300 are located at the assembly position. The rotation component 12 is used to drive the battery cell 100 to rotate circumferentially so that the cover plate 400 and the pole tab 300 are located at the assembly position. In this embodiment, the assembly position is specifically as follows Figure 7 and Figure 8 The upper horizontal position shown. The detection component 11 can feed back the detection information to the control system. When it is detected that the cover plate 400 and the pole tab 300 are not in the upper horizontal position, the control system controls the rotation component 12 to rotate, so that the battery cell 100 rotates circumferentially to adjust the position of the cover plate 400 and the pole tab 300, until the detection component 11 detects that the cover plate 400 and the pole tab 300 are in the upper horizontal position, the control system controls the rotation component 12 to stop rotating, the deviation correction is completed, and then the transfer mechanism 30 transfers the corrected battery cell 100 to the support seat 21 for shelling operation. Among them, the control system is a prior art, and this embodiment can use any control system and electrical connection method that can realize the above functions, which will not be repeated here.

[0064] In an optional embodiment, if Figure 7 and Figure 8 As shown, the rotating assembly 12 includes a bracket 121, a plurality of rollers 122, a first transmission wheel 124, a second transmission wheel 125 and a rotating drive member 123. The plurality of rollers 122 are rotatably arranged on the bracket 121. Each two adjacent rollers 122 form a bearing portion for bearing a battery cell 100. The surface of the battery cell 100 contacts the two rollers 122. The end of each roller 122 is fixedly connected to the second transmission wheel 125. The rotating drive member 123 is fixedly connected to the bracket 121. The output shaft of the rotating drive member 123 is connected to the first transmission wheel 124. The synchronous belt 126 is covered on the outer periphery of the first transmission wheel 124 and the two adjacent second transmission wheels 125 and is tensioned by the first transmission wheel 124 and the two second transmission wheels 125. The rotating drive member 123 is preferably a motor.

[0065] like Figure 6 and Figure 7 As shown, the detection component 11 includes a photoelectric sensor 111, a first optical fiber sensor 112 and a second optical fiber sensor 113. The transmitting end and the receiving end of the photoelectric sensor 111 are respectively fixed on both sides of the bracket 121 along the Y-axis direction. The photoelectric sensor 111 is used to detect whether there is a battery cell 100 on the roller 122. The first optical fiber sensor 112 and the second optical fiber sensor 113 are also fixed on the bracket 121. The second optical fiber sensor 113 is used to detect the position of the cover plate 400, and the first optical fiber sensor 112 is used to detect the position of the pole ear piece 300.

[0066] The transfer mechanism 30 places the battery cell 100 from the transport line onto the roller 122. When the photoelectric sensor 111 senses that the battery cell 100 is in place, and the second optical fiber sensor 113 senses that the position of the cover plate 400 is offset, a trigger signal is generated, so that the control system controls the rotation drive member 123 to start. The rotation drive member 123 drives the first transmission wheel 124 to rotate, and drives the synchronous belt 126 and the two second transmission wheels 125 to rotate. The two second transmission wheels 125 drive the two rollers 122 to rotate. The rotation of the two rollers 122 can rotate the battery cell 100, thereby performing rotation correction on the cover plate 400 and the pole tab 300. When the battery cell 100 rotates to the position as shown in FIG. Figure 7 and Figure 8 When the cover plate 400 and the pole ear piece 300 are in the upper horizontal position, the first optical fiber sensor 112 is just blocked by the pole ear piece 300. At this time, the first optical fiber sensor 112 is triggered and a feedback signal is given to the control system. The control system controls the rotating drive member 123 to stop rotating, and the correction action is completed at this time.

[0067] In another optional embodiment, the detection mechanism may also be two displacement sensors, which detect whether the cover plate 400 is in the upper horizontal position by respectively detecting the horizontal heights of both sides of the cover plate 400. In another optional embodiment, the detection mechanism may also be a CCD camera, which detects the position of the cover plate 400 by taking pictures.

[0068] In an optional embodiment, if Figure 1 As shown, the transfer mechanism 30 includes a frame 31, a second mobile module 32, a connecting plate 33, a third mobile module 34 and a clamping part 35. The frame 31 is in the form of a gantry. The second mobile module 32 is fixed on the frame 31 and can output movement along the X-axis direction. The connecting plate 33 is fixedly connected to the output end of the second mobile module 32. The third mobile module 34 is fixedly connected to the connecting plate 33 and can output movement along the vertical direction. The clamping part 35 is fixedly connected to the output end of the third mobile module 34. The clamping part 35 includes a plurality of finger cylinders and a clamping claw fixedly connected to the output end of the finger cylinder. The clamping part 35 can grab a plurality of battery cells 100 at one time. Through the cooperation of the second mobile module 32 and the third mobile module 34, the battery cell 100 can be grabbed from the transport line to the deviation correction mechanism 10, and the battery cell 100 can be grabbed from the deviation correction mechanism 10 to the shell insertion mechanism 20, thereby realizing the automatic transfer of the battery cell 100.

[0069] It should be noted that in this embodiment, the second moving module 32 and the third moving module 34 are both in the form of a motor screw nut and a guide rail slider, and their specific structures and working principles are all prior art and will not be described in detail here. In other embodiments, other linear drive structures such as a cylinder, an electric push rod or a motor-driven synchronous belt slide can also be selected according to actual needs, and no specific limitation is made here.

[0070] In another optional embodiment, the transfer mechanism 30 may also be in the form of a clamping portion 35 provided at the end of a robotic arm, which is not specifically limited here.

[0071] Combination Figures 1 to 8 The working process of the above-mentioned battery cell shelling device is as follows:

[0072] 1) The clamping part 35 cooperates with the second movable module 32 and the third movable module 34 to clamp the battery cell 100 from the transport line, and places the battery cell 100 on the roller 122 of the correction mechanism 10, and the detection component 11 cooperates with the rotating component 12 to correct the battery cell 100, so that the cover plate 400 and the pole tab 300 of the battery cell 100 are located in the upper horizontal position;

[0073] 2) The clamping part 35 cooperates with the second movable module 32 and the third movable module 34 to grab the battery cell 100 from the correcting mechanism 10 to the guide groove 211 of the supporting seat 21, and the upper driving member 222 drives the upper guide member 224 to descend, and at the same time, the lower driving member 223 drives the lower guide member 225 to rise, so that the upper guide member 224 and the lower guide member 225 are connected to form a complete guide hole 221, and the guide hole 221 is coaxially connected with the guide groove 211, and the fixing component 23 pushes one end of the battery shell 200 into the guide hole 221, and then the light pressure driving member 251 drives the light pressure plate 252 to move down and lightly press the battery shell 200 to prevent the battery shell 200 from moving upward;

[0074] 3) The first moving module 241 drives the push rod 243 to move along the first direction, so that the push rod 243 pushes the battery cell 100 into the battery shell 200. When the battery cell 100 is pushed to the position where its cover plate 400 is about to reach the upper positioning member 224, the first moving module 241 stops moving, and then the upper driving member 222 drives the upper guide member 224 to rise to avoid the cover plate 400. Then the first moving module 241 drives the push rod 243 to push the battery cell 100 for the second time. When the pressure sensor 247 senses that the shell entry pressure reaches the preset requirement, it indicates that the shell entry is completed, and at this time, the first moving module 241 stops driving;

[0075] 4) After a row of battery cells 100 are shelled, the first moving module 241, the lower driving member 223 and the light pressure driving member 251 are reset, and then the driving member 232 of the fixing assembly 23 is reset. After that, the fixing assembly 23 takes the battery shell 200 after the battery cells 100 are shelled to the next station along the circulation mechanism. At the same time, the transfer mechanism 30 grabs another row of battery cells 100 from the conveyor line and places them on the roller 122 of the correction mechanism 10, and the cycle is repeated.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
