[0002] Batteries are not only used in portable electronic devices but also widely used in large and medium-sized electric devices such as electric vehicles, electric bicycles, and electric tools. Therefore, the safety requirements for batteries are getting higher and higher. To assemble a battery electrode group into a battery case, usually, an operator uses a manual method of inserting into the case, that is, manually aligns one end of the battery electrode group with the battery case and then inserts the battery electrode group into the battery case.

[0003] Currently, during the process of assembling a battery electrode group into a battery case, when the battery electrode group is inserted into the battery case, since the force application direction during manual insertion is not parallel to the axis of the battery case, it is easy for the electrode group to be subjected to unbalanced external forces, which may then cause deviation, resulting in unreasonable utilization of the internal space of the battery, affecting the capacity and performance consistency of the battery. Or when inserting, due to insufficient positioning accuracy, the electrode group may not be accurately docked with other components inside the battery case, such as electrode connection pieces, affecting the electrical performance of the battery. In severe cases, it may even cause an internal short circuit, leading to safety problems. Therefore, it is necessary to propose a device for assembling a battery electrode group into a battery case.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, with the cooperation of the positioning offset correction component, during the process of inserting the battery electrode group into the battery case, the visual recognition sensor array continuously monitors the position change of the battery electrode group. Once a new offset is detected, the positioning offset correction component will repeat the above adjustment process to achieve real-time dynamic adjustment, ensuring the accuracy of the entire insertion process.

During the insertion process of the battery electrode group, if excessive insertion resistance or position deviation is detected, the displacement electric guide rail structure will automatically adjust the position of the battery case placement seat to ensure the smooth progress of the insertion process. During the battery full-pressure stage, if uneven pressure or excessive pressure is detected, the pneumatic contact spring rod group will automatically adjust the pressure to ensure the fitting quality between the battery electrode group and the battery case, enabling the overall formation of an automatic assembly operation, reducing the error of manual insertion, realizing the full-automatic process from the feeding, conveying, insertion to deviation correction of the battery electrode group, reducing manual intervention, and improving production efficiency and product consistency.

Detailed implementation mode

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Refer to Figure 1 - Figure 8 As shown in the figure: A device for assembling a battery electrode group into a battery case includes an automated assembly component 100 for battery electrode group and a positioning offset correction component 200. The positioning offset correction component 200 is installed in the step of inserting the battery electrode group into the battery case by the automated assembly component 100 for battery electrode group. When the battery electrode group moves towards the battery case and is about to be inserted, the positioning offset correction component 200 is immediately activated. The positioning offset correction component 200 has a visual recognition sensor array and an adjusting and guiding flexible jaw 215. By using the visual recognition sensor array to monitor the relative position of the battery electrode group and the battery case in real time, once it is detected that the battery electrode group has a positioning offset, the adjusting and guiding flexible jaw 215 can, without damaging the battery electrode group, accurately adjust the position and angle of the battery electrode group under the action of the electromagnetic guide rod 214 installed on the outer circumference of the adjusting and guiding flexible jaw 215, ensuring that the battery electrode group is smoothly and accurately inserted into the battery case.

[0029] The positioning offset correction component 200 includes a mounting fixed plate 201. A connecting plate frame 202 is fixedly connected to the side end of the mounting fixed plate 201. A set of sliding grooves are symmetrically formed on the top wall surface of the connecting plate frame 202. An air-operated universal joint rod 203 is slidably connected inside the sliding grooves. The top of the air-operated universal joint rod 203 is fixedly connected to a connecting block. Tooth edges 205 and guide posts 206 are respectively connected to the left and right side ends of the connecting block.

[0030] A transverse lead screw guide 204 is installed on the top of the connecting plate frame 202. The transverse lead screw guide 204 has a threaded lead screw and a guide sliding column. A transmission gear 207 is meshed and connected to the side end of the threaded lead screw. A positioning sliding seat 209 is slidably connected to the outside of the guide sliding column. An auxiliary gear 208 is installed on the surface of the positioning sliding seat 209. A shaft column is connected to the bottom center end of the auxiliary gear 208. The shaft column passes through the positioning sliding seat and is connected to the transmission gear 207. An electromagnetic blocker is installed at the bottom of the auxiliary gear 208.

[0031] Both the tooth edge 205 and the guide post 206 are slidably connected inside the positioning sliding seat 209. The auxiliary gear 208 is meshed and connected to the tooth edge 205. Fixed blocks 210 are fixedly connected to the top of the side ends of a set of connecting blocks.

[0032] A rotating arc frame 212 is rotatably connected to the top of the fixed block 210. Convex teeth 217 are further installed on the inner wall surface of the rotating arc frame 212. A driving damping rotating part 218 is meshed and connected inside the convex teeth 217. The driving damping rotating part 218 and the fixed block 210 are fixedly connected through an adapter block. A sensor mounting ring frame 213 is fixedly connected to the top of the rotating arc frame 212. The visual recognition sensor array is installed around the surface of the sensor mounting ring frame 213.

[0033] An electromagnetic guide rod 214 is installed inside the sensor mounting ring frame 213 and is rotatably connected to the central end frame of the sensor mounting ring frame 213. A memory metal contact 216 is installed on the surface of the adjusting guide flexible jaw 215.

[0034] In this embodiment, first, when the battery electrode group automatic assembly component 100 executes the instruction to insert the battery electrode group into the battery case, the battery electrode group moves towards the battery case. At the same time, the positioning offset correction component 200 is activated. The visual recognition sensor array is installed around the sensor mounting ring frame 213 and starts to capture the relative position information between the battery electrode group and the battery case in real time.

[0035] Subsequently, the visual recognition sensor array uses image recognition algorithms to analyze the collected images, accurately calculate the position deviation between the battery electrode group and the battery case. Once a positioning deviation of the battery electrode group is detected, the positioning deviation correction assembly 200 immediately responds. Secondly, during the response process, the adjustment guiding flexible gripper 215 starts to work. Using the electromagnetic guide rod 214 installed inside the sensor mounting ring frame 213, which is rotatably connected to the central end frame of the sensor mounting ring frame 213, after the electromagnetic guide rod 214 is energized, it generates a magnetic field, which interacts with the shape memory metal contact 216 on the surface of the adjustment guiding flexible gripper 215, and the adjustment guiding flexible gripper 215 is adjusted by the magnetic force to preliminarily clamp and adjust the position and angle of the battery electrode group.

[0036] At the same time, the transverse screw rod guide 204 starts to play a role. The transmission gear 207 meshes with the threaded screw rod, and the auxiliary gear 208 is coaxially connected to the transmission gear 207. When the external control system issues an adjustment instruction, the motor drives the threaded screw rod to rotate, driving the transmission gear 207 to rotate, causing the positioning sliding seat 209 to move horizontally on the guiding sliding column. At this time, during the movement of the positioning sliding seat 209, the auxiliary gear 208 meshes with the tooth edge 205, pushing the tooth edge 205 and the guiding column 206 to move within the positioning sliding seat 209, further finely adjusting the position of the adjustment guiding flexible gripper 215, and under the action of the pneumatic universal joint rod 203, ensuring the stability of the adjustment of the adjustment guiding flexible gripper 215. In addition, the rotating arc frame 212 can achieve angle adjustment. Using the driving damping rotating part 218 meshing with the convex teeth 217, when the angle needs to be adjusted, the driving damping rotating part 218 rotates driven by the connecting block, thereby driving the rotating arc frame 212 to rotate around the fixed block 210, accurately adjusting the angles of the visual recognition sensor array and the adjustment guiding flexible gripper 215 to ensure that the battery electrode group can be inserted into the battery case accurately without error.

[0037] Moreover, during the process of inserting the battery electrode group into the battery case, the visual recognition sensor array continuously monitors the position change of the battery electrode group. Once a new deviation is detected, the positioning deviation correction assembly 200 will repeat the above adjustment process to achieve real-time dynamic adjustment, ensuring the accuracy of the entire insertion process. Through the coordinated work of the electromagnetic guide rod 214, the transverse screw rod guide 204, and the rotating arc frame 212, this device realizes multi-dimensional adjustment of the adjustment guiding flexible gripper 215 in three-dimensional space, enabling rapid and accurate correction of various positioning deviations, greatly improving the assembly accuracy. That is, during the process of inserting the battery electrode group into the battery case, the visual recognition sensor array continuously monitors the position change of the battery electrode group. Once a new deviation is detected, the positioning deviation correction assembly 200 will repeat the above adjustment process to achieve real-time dynamic adjustment, ensuring the accuracy of the entire insertion process. With the organic combination of multi-dimensional adjustment, non-contact protection, and real-time feedback, this device can flexibly handle various complex situations during the assembly process, significantly improving the stability and reliability of the battery electrode group assembly.

[0038] Example 2: According to Figure 1 - Figure 3 As shown in the figure, the automatic assembly component 100 of the battery electrode group includes a base. A battery electrode group placement seat 101 and a battery case placement seat 106 are respectively arranged on the surface of the base. A first external feeding structure is arranged at the side end of the battery electrode group placement seat 101. The battery case placement seat 106 is arranged at the side end of the battery electrode group placement seat 101, and a second external feeding structure is arranged at the side end of the battery case placement seat 106.

[0039] A horizontal floating linear guide rail 103 is arranged on the top of the base. A position pressing plate 102 is slidably connected inside the horizontal floating linear guide rail 103. An array of suction nozzles 104 is arranged at the bottom of the position pressing plate 102.

[0040] A displacement electric guide rail structure 105 is arranged on the surface of the base. The top end inside the displacement electric guide rail structure 105 is slidably connected to the battery case placement seat 106.

[0041] A cylinder frame 107 is arranged on the surface of the top wall at the side end of the base. Vertical sliding grooves 108 are symmetrically arranged on the inner wall surface of the frame body of the cylinder frame 107. A position adjustment seat 109 is slidably connected outside the vertical sliding grooves 108. A pneumatic contact spring rod group 110 is tightly connected to the side end of the position adjustment seat 109. A battery pressing plate 111 is arranged at the bottom of the pneumatic contact spring rod group 110.

[0042] In this embodiment, when receiving the battery electrode group assembly operation instruction, the entire automatic assembly component 100 of the battery electrode group is started. The first external feeding structure transports the battery electrode group to the battery electrode group placement seat 101, and the second external feeding structure transports the battery case to the battery case placement seat 106.

[0043] Then the horizontal floating linear guide rail 103 starts to work, driving the position pressing plate 102 to slide along the guide rail to the upper part of the battery electrode group placement seat 101. The position pressing plate 102 descends, so that the array of suction nozzles 104 at the bottom contacts the battery electrode group, and the battery electrode group is firmly sucked by the suction force. The horizontal floating linear guide rail 103 uses magnetic levitation technology, reducing the friction and wear during the sliding process, improving the accuracy and speed of the movement of the position pressing plate 102, and having higher stability and reliability compared with the traditional linear guide rail.

[0044] After sucking the battery electrode group, the position pressing plate 102 is driven by the horizontal floating linear guide rail 103 to transfer the battery electrode group from above the battery electrode group placement seat 101 to above the battery case placement seat 106. During this process, the horizontal floating linear guide rail 103 can accurately control the movement position and speed of the position pressing plate 102 to ensure that the battery electrode group accurately aligns with the opening of the battery case.

[0045] After the battery electrode group is aligned with the battery housing, the position pressing plate 102 slowly descends, inserting the battery electrode group into the battery housing. At the same time, the displacement electric guide rail structure 105 starts to work. According to the insertion depth and position of the battery electrode group, it adjusts the position of the battery housing placement seat 106 in real time to ensure that the battery electrode group can be smoothly inserted into the battery housing. The displacement electric guide rail structure 105 adopts an electric drive mode, which can achieve precise displacement control, improving the accuracy and efficiency of the insertion of the battery electrode group.

[0046] When the battery electrode group is inserted into the battery housing and then corrected by the positioning offset correction component 200, the position adjustment seat 109 on the cylinder frame 107 slides down in the vertical sliding groove 108. The pneumatic contact spring rod group 110 at the side end of the position adjustment seat 109 drives the battery pressing plate 111 to descend, applying a certain pressure to the battery electrode group to make the battery electrode group fit tightly inside the battery housing, ensuring the stable performance of the battery. The pneumatic contact spring rod group 110 can automatically adjust the pressure according to the different thicknesses and hardnesses of the battery electrode group, avoiding damage to the battery electrode group.

[0047] During the entire operation process, each component cooperates with each other to achieve dynamic adjustment. For example, when the array suction nozzle 104 sucks the battery electrode group, if it detects insufficient suction or the position deviation of the battery electrode group, the control system will timely adjust the position of the position pressing plate 102 and the suction force of the suction nozzle. During the insertion process of the battery electrode group, if it detects excessive insertion resistance or position deviation, the displacement electric guide rail structure 105 will automatically adjust the position of the battery housing placement seat 106 to ensure the smooth progress of the insertion process. During the battery pressing stage, if it detects uneven pressure or excessive pressure, the pneumatic contact spring rod group 110 will automatically adjust the pressure size to ensure the fitting quality between the battery electrode group and the battery housing.

Its working principle is a well-known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the vision recognition sensor array and the electromagnetic blocker will not be explained in detail.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
