[0001] The present invention relates to the technical field of battery manufacturing, and more particularly, to a top cover feeding device and method. Background Art

[0002] The existing battery production and manufacturing process mainly includes three main parts: electrode manufacturing, cell assembly, and formation and grading. Among them, tab welding is the main link in the cell assembly process. In the cell assembly process, it is necessary to assemble the top cover to the cell after tab welding.

[0003] In the conventional top cover assembly technology, the cover plate and the pole column assembly are usually integrally assembled. This assembly method has some problems that are difficult to overcome in actual production. Specifically, when the cover plate and the pole column assembly are assembled to the cell together, the assembly operation is realized by positioning through the pole column assembly and the adapter tab pole on the cell. In this assembly process, due to the assembly tolerance between the cover plate and the pole column assembly, the assembly tolerance between the cover plate and the adapter tab after assembly does not meet the assembly requirements, resulting in the cover plate in the top cover not being able to press well on the sealing ring of the adapter tab pole, reducing the assembly yield, and ultimately affecting the sealing performance of the cell.

[0004] As can be seen from the above, there is a problem of low assembly yield of the cell top cover in the prior art. Summary of the Invention

[0038] In order to solve the problem of low assembly yield of the cell top cover in the prior art, the present application provides a top cover loading device and method.

[0039] Such as Figure 1As shown in the figure, the battery cell structure in this embodiment includes a top cover, a connecting piece 3, and a battery cell body 6. Among them, the top cover includes a cover plate 1 and a pole column assembly 2 arranged on the cover plate 1. Among them, there are two pole column assemblies 2, and the two pole column assemblies 2 are respectively located at both ends of the cover plate 1. A connecting piece pole column 4 is arranged on the connecting piece 3, and the connecting piece 3 is electrically connected to the tab of the battery cell body 6. The pole column assembly 2 has a through-hole structure penetrating the cover plate 1, that is, the pole column assembly 2 has a through-hole structure, and the cover plate 1 has an assembly hole communicating with the through-hole structure on the pole column assembly 2, and the pole column assembly 2 is arranged in the assembly hole of the cover plate 1. Specifically, the cover plate 1 is provided with an assembly hole, and at least a part of the pole column assembly 2 is arranged in the assembly hole. The pole column assembly 2 is also provided with a coaxially arranged through-hole structure. The connecting piece pole column 4 passes through the assembly hole of the cover plate 1 and the through-hole structure of the pole column assembly 2 and protrudes from the top surface of the pole column assembly 2, and the connecting piece pole column 4 is welded to the pole column assembly 2. Further, the battery cell structure further includes a sealing ring 5, and the sealing ring 5 is sleeved on the connecting piece pole column 4, and the sealing ring 5 cooperates with the step surface of the connecting piece pole column 4.

[0040] As Figures 2 to 7 shown in the figure, the present application provides a top cover feeding device, which includes a top cover transfer member 10, a first feeding assembly 30, and a second feeding assembly 40. The top cover transfer member 10 includes a first grasping mechanism 11 and a second grasping mechanism 12, which are used to respectively grasp and fix the pole column assembly 2 and the cover plate 1 and transport them to the feeding position. The first feeding assembly 30 is used to transport the cover plate 1 from the feeding position to the assembly position. The second feeding assembly 40 is used to transport the pole column assembly 2 from the feeding position to the assembly position.

[0041] By setting that the top cover feeding device includes a top cover transfer member 10, a first feeding assembly 30, and a second feeding assembly 40, the top cover transfer member 10 includes a first grasping mechanism 11 and a second grasping mechanism 12, which are used to respectively grasp and fix the pole column assembly 2 and the cover plate 1 and transport them to the feeding position, the first feeding assembly 30 is used to transport the cover plate 1 from the feeding position to the assembly position, and the second feeding assembly 40 is used to transport the pole column assembly 2 from the feeding position to the assembly position. In this way, by setting that the top cover transfer member 10 successively grasps and fixes the pole column assembly 2 and the cover plate 1 and transports them to the feeding position, the simultaneous transportation of the entire top cover by a single transfer component in one trip is realized, avoiding the use of multiple transfer components to respectively transport the pole column assembly 2 and the cover plate 1, thereby reducing the position error generated by the separate operation of multiple transfer components, enabling the pole column assembly 2 and the cover plate 1 at the feeding position to be in an accurate relative position, finally reducing the assembly tolerance between the pole column assembly 2 and the cover plate 1, ensuring the yield rate of the top cover assembly. Further, by using two feeding assemblies to respectively transport the cover plate 1 and the pole column assembly 2, the separate feeding of the cover plate 1 and the pole column assembly 2 is realized, reducing the feeding and assembly difficulty, also reducing the accumulation of assembly tolerance between the cover plate 1 and the pole column assembly 2, ensuring the coaxiality between the pole column assembly 2 and the cover plate 1, and enabling the top cover to have a high assembly yield rate.

[0042] In this embodiment, as Figures 2 to 3 shown, the top cover feeding device further includes a gantry 70, and the first feeding assembly 30 and the second feeding assembly 40 are respectively movably connected to the gantry 70, so as to transport the cover plate 1 and the pole column assembly 2 to the assembly positions respectively.

[0043] Specifically, the gantry 70 includes a support base and a horizontally extending rail located at the top of the support base. A Y-axis driving mechanism is arranged on the horizontally extending rail, and the top cover transfer member 10, the first feeding assembly 30 and the second feeding assembly 40 respectively move along the horizontally extending rail under the drive of the Y-axis driving mechanism.

[0044] Furthermore, as Figure 3 shown, the top cover feeding device further includes a Z-axis driving mechanism 80. The top cover transfer member 10 is drivingly connected to the Z-axis driving mechanism 80, and the Z-axis driving mechanism 80 is arranged on the Y-axis driving mechanism, so that the top cover transfer member 10 can not only move up and down under the drive of the Z-axis driving mechanism 80, but also move horizontally following the Y-axis driving mechanism.

[0045] In this embodiment, the Y-axis driving mechanism and the Z-axis driving mechanism 80 are servo motors, electric cylinders or air cylinders.

[0046] In this embodiment, the first grasping mechanism 11 and the second grasping mechanism 12 are arranged with an upper and lower dislocation. Specifically, corresponding to the pole column assembly 2 being assembled on the upper end surface of the cover plate 1, the overall height of the first grasping mechanism 11 is higher than that of the second grasping mechanism 12, and the height difference between the two is adapted to the height difference between the cover plate 1 and the pole column assembly 2, so that after the first grasping mechanism 11 and the second grasping mechanism 12 respectively grasp the cover plate 1 and the pole column assembly 2, the pole column assembly 2 and the cover plate 1 located on the top cover transfer member 10 will not interfere with each other.

[0047] In this embodiment, the first grasping mechanism 11 is a suction cup mechanism. Specifically, as Figures 4 to 7 shown, the first grasping mechanism 11 includes a suction cup structure 111. There are two suction cup structures 111, and the two suction cup structures 111 are respectively located at both ends of the first grasping mechanism 11 and are arranged in one-to-one correspondence with the two pole column assemblies 2 of the top cover. Through the above arrangement, the two pole column assemblies 2 of the top cover can be accurately adsorbed and fixed, ensuring the stability and accuracy of feeding.

[0048] Furthermore, as Figures 4 to 7 shown, the first grasping mechanism 11 further includes a first driving member 112, and the first driving member 112 is drivingly connected to the suction cup structure 111 to drive the suction cup structure 111 to move up and down.

[0049] In this embodiment, the suction cup structure 111 includes a plurality of suction cups, and the plurality of suction cups are evenly distributed relative to the center of the pole column assembly 2. That is to say, when the suction cup structure 111 adsorbs the pole column assembly 2, the plurality of suction cups are centrosymmetrically arranged relative to the center of the pole column assembly 2, so as to ensure uniform and stable adsorption and prevent the pole column assembly 2 from having a horizontal deviation.

[0050] In this embodiment, the second grasping mechanism 12 is a jaw mechanism. Specifically, as Figures 4 to 7 shown, the second grasping mechanism 12 includes a clamping portion 121. There are a plurality of clamping portions 121, and the plurality of clamping portions 121 are divided into multiple groups in pairs. The two clamping portions 121 in each group are respectively located on both sides of the cover plate 1, so as to clamp the side edge of the cover plate 1. The multiple groups of clamping portions 121 are symmetrically arranged relative to the center of the cover plate 1 along the length direction of the cover plate 1. That is to say, when the clamping portion 121 clamps the cover plate 1, the multiple clamping portions 121 are centrosymmetrically arranged relative to the center of the cover plate 1, so as to ensure uniform and stable clamping and prevent the cover plate 1 from having a horizontal deviation.

[0051] In a specific embodiment of the present application, as Figure 4 shown, there are four clamping portions 121, and the four clamping portions 121 are divided into two groups. The two groups of clamping portions 121 are respectively located on both sides of the center of the cover plate 1.

[0052] Furthermore, as Figures 4 to 7 shown, the second grasping mechanism 12 further includes a second driving member 122, and the second driving member 122 is drivingly connected to the clamping portion 121, so as to drive each group of clamping portions 121 to approach or move away from each other. Specifically, the second driving member 122 includes two sub-driving members, and the two sub-driving members are respectively drivingly connected to the two clamping portions 121 of each group. When the two sub-driving members drive the two clamping portions 121 of each group to approach each other, the clamping portion 121 clamps and fixes the cover plate 1; when the two sub-driving members drive the two clamping portions 121 of each group to move away from each other, the clamping portion 121 releases the clamping and fixing of the cover plate 1.

[0053] As Figures 2 to 3 shown, the top cover feeding device further includes a separating assembly 20, and the separating assembly 20 is used to separate the pole column assembly 2 and the cover plate 1 at the feeding position, so that the first feeding assembly 30 and the second feeding assembly 40 can respectively transport the cover plate 1 and the pole column assembly 2 to the assembly position.

[0054] As Figure 2 、 Figures 8 to 10As shown, the separation assembly 20 includes a guide rail 21, a cover plate receiving member 22 and a pole assembly receiving member 23. The pole assembly receiving member 23 is arranged at one end of the guide rail 21 and the cover plate receiving member 22 is movably connected to the guide rail 21. The cover plate receiving member 22 and the pole assembly receiving member 23 are arranged in an upper and lower offset manner. The top cover transport member 10 successively places the cover plate 1 and the pole assembly 2 on the cover plate receiving member 22 and the pole assembly receiving member 23. Specifically, the extension direction of the guide rail 21 is perpendicular to the extension direction of the horizontal extension rail.

[0055] Specifically, the cover plate 1 and the pole assembly 2 are staggered along the X-axis direction at the loading position, that is, the loading routes of the two are parallel. After the top cover transfer part 10 transports the top cover from the coding module through the Y-axis drive mechanism along the horizontal extension rail to the top of the cover receiving part 22, the top cover transfer part 10 is driven by the Z-axis drive mechanism 80 to the cover discharge position, and at the same time, the clamping part 121 for clamping the cover 1 is released, and then the top cover transfer part 10 rises to the safety position, so that the cover 1 is placed in the cover receiving part 22 for positioning, and the cover receiving part 22 moves along the guide rail 21 to the cover loading station at the other end, exposing the lower pole assembly receiving part 23, and the top cover transfer part 10 continues to descend to the pole assembly discharge position, and the suction cup structure 111 thereon breaks the vacuum, thereby placing the pole assembly 2 on the pole assembly receiving part 23, and the top cover transfer part 10 rises to the safety position again, and moves horizontally to the coding module, thereby cooperating with the separation component 20 to complete the transfer and separation of the top cover.

[0056] like Figure 2 and Figure 8 As shown, the top cover feeding device further includes a first camera 50. The first camera 50 is located on the movement path of the first feeding assembly 30, and is used to capture a first image of the cover plate 1 in the first feeding assembly 30.

[0057] Further, such as Figure 2 As shown, the first loading assembly 30 includes a second camera 33. The second camera 33 is used to capture a second image of the adapter plate pole 4 at the assembly position. The first image and the second image are used to perform position correction compensation on the first loading assembly 30.

[0058] In this embodiment, the top cover feeding device also includes a controller, and the top cover transport member 10, the separation component 20, the first feeding component 30, the second feeding component 40 and the first camera 50 are all electrically connected to the controller. The above components all perform corresponding operations under the control of the preset program of the controller, thereby realizing automatic feeding. Furthermore, in the process of position correction compensation, the first image is used to obtain the relative position of the cover plate 1 in the first feeding component 30, so as to refer to the position of the adapter plate pole 4 in the second image, and adjust the position of the first feeding component 30 after reaching the assembly position to align with the adapter plate pole 4.

[0059] In addition, when the pole assembly 2 and the cover plate 1 are assembled to the battery cell body 6 at the same time, the state of the sealing ring 5 on the adapter plate pole 4 is often difficult to monitor in real time, which may cause problems of poor sealing during the use of the battery, thus affecting the performance and life safety of the battery. In this embodiment, by providing the second camera 33, it is possible to take pictures of the adapter plate pole 4 before and after the assembly of the cover plate 1 and the adapter plate pole 4, so as to obtain the state of the sealing ring 5, ensure that the state of the sealing ring 5 is controllable, and thus improve the quality stability of the battery cell.

[0060] As Figure 2 and Figure 8 shown, the top cover feeding device further includes a third camera 60. The third camera 60 is electrically connected to the controller. The third camera 60 is located on the movement route of the second feeding assembly 40 and is used to take a third image of the pole assembly 2 in the second feeding assembly 40.

[0061] As Figure 2 and Figure 8 shown, the second feeding assembly 40 includes a fourth camera 43. The fourth camera 43 is used to take a fourth image of the adapter plate pole 4 after being assembled with the cover plate 1 at the assembly position. Among them, the third image and the fourth image are used for position deviation correction and compensation of the second feeding assembly 40. Specifically, during the position deviation correction and compensation process, the third image is used to obtain the relative position of the pole assembly 2 in the second feeding assembly 40, so as to be referenced with the position of the adapter plate pole 4 in the fourth image, and adjust the position of the second feeding assembly 40 after reaching the assembly position to align the cover plate 1 and the adapter plate pole 4.

[0062] It can be understood that when the two feeding assemblies transport the cover plate 1 and the pole assembly 2, the cover plate 1 and the pole assembly 2 are both kept in a normal horizontal state, and the first camera 50 and the third camera 60 are located at the lower part of the top cover feeding device, so as to take pictures of the bottoms of the cover plate 1 and the pole assembly 2 respectively.

[0063] In this embodiment, by providing a plurality of cameras to perform photo compensation and deviation correction before feeding the pole assembly 2 and the cover plate 1, the assembly accuracy is improved and the assembly yield is increased.

[0064] As Figure 2 shown, the first feeding assembly 30 further includes a first main body 31 and a first jaw 32. The first main body 31 is movably connected to the gantry 70. Specifically, the first main body 31 is movably connected to the horizontally extending rail. The first jaw 32 is connected to the first main body 31 in a liftable manner, and the first jaw 32 is used to clamp the cover plate 1.

[0065] As Figure 2 and Figure 8As shown, the second loading component 40 further includes a second main body portion 41 and a second jaw 42. The second main body portion 41 is movably connected to the gantry 70. Specifically, the second main body portion 41 is movably connected to the horizontally extending rail. The second jaw 42 is vertically movably connected to the second main body portion 41, and the second jaw 42 is used for clamping the pole column assembly 2.

[0066] In this embodiment, the first main body portion 31 and the second main body portion 41 may be Y-axis drive mechanisms.

[0067] In this embodiment, the first jaw 32 and the second jaw 42 may be the same components as the top cover transfer member 10, so as to respectively use the first grasping mechanism 11 and the second grasping mechanism 12 to grasp and fix the pole column assembly 2 and the cover plate 1.

[0068] It can be understood that the two loading components in this embodiment mainly transfer the cover plate 1 on the cover plate receiving member 22 and the pole column assembly 2 on the pole column receiving member 23 to the assembly positions respectively for assembly, and play the roles of transfer, positioning, and assembly in this process.

[0069] In this embodiment, when the top cover is transferred to the loading position by the top cover transfer member 10 and separated by the separating component 20, the first loading component 30 moves to the cover plate receiving member 22 and descends, grabs the cover plate 1 from the cover plate receiving member 22, then traverses horizontally through the horizontally extending rail to the first camera 50 for taking a photo. The controller processes the photo taken by the first camera 50 to confirm the specific position of the cover plate 1. When the first loading component 30 moves to the assembly position, the second camera 33 installed on the first loading component 30 takes a photo and identifies the adapter pole column 4 with the seal ring 5 already assembled at the assembly position. The specific positions of the adapter pole column 4 and the cover plate 1 are jointly confirmed through the first image and the second image, and visual correction compensation parameters are set for the first loading component 30; the first loading component 30 traverses horizontally to the compensated cover plate loading position according to the visual correction compensation parameters, and the first jaw 32 of the first loading component 30 descends to assemble the cover plate 1 and the adapter pole column 4. After the assembly is completed, the first jaw 32 rises, and the first loading component 30 traverses in the reverse direction, aligns the second camera 33 with the assembled cover plate 1 for taking a photo inspection to check the state of the seal ring 5 after the cover plate 1 is assembled. The first loading component 30 returns to the cover plate receiving member 22 through the horizontally extending rail to complete the loading of the cover plate 1.

[0070] Further, the second loading component 40 moves to the pole component receiver 23 and descends, takes out the pole component 2 from the pole component receiver 23 through the suction cup 421, the second loading component 40 moves to the third camera 60 through the horizontally extending rail, and takes a picture and positions the inner circle of the pole component 2 through the third camera 60; after the second loading component 40 continues to move to the assembly position, it takes a picture through the fourth camera 43 installed on the second loading component 40 to identify the position of the adapter plate pole 4, and combines the third image and the fourth image to continue visual deviation correction and compensation for the assembly of the pole component 2; the second loading component 40 moves to the compensated pole component loading position according to the visual deviation correction compensation value, the second jaw 42 descends, and the assembly of the pole component 2 with the adapter plate pole 4 and the cover plate 1 is completed. After the assembly is completed, the second jaw 42 rises, and the second loading component 40 returns to the pole component receiver 23 through the horizontally extending rail to complete the loading of the pole component 2.

[0071] As Figure 11 shown, the present application also provides a method for loading the top cover. The loading method is implemented by using the above-mentioned top cover loading device. The loading method includes: providing a pre-assembled top cover; using the top cover transfer member 10 to respectively grasp and fix the cover plate 1 and the pole component 2 of the top cover and transport them to the loading position; using the first loading component 30 to transport the cover plate 1 from the loading position to the assembly position, and assembling the cover plate 1 with the adapter plate pole 4; using the second loading component 40 to transport the pole component 2 from the loading position to the assembly position, and assembling the pole component 2 with the cover plate 1 and the adapter plate pole 4.

[0072] In this embodiment, the top cover is in a pre-assembled state before transportation, that is, the pole component 2 has been placed on the cover plate 1, so that the top cover transfer member 10 can grasp the cover plate 1 and the pole component 2 in sequence without horizontal movement, saving time and improving the loading efficiency.

[0073] In this embodiment, during the process of the first loading component 30 transporting the cover plate 1 from the loading position to the assembly position, the loading method further includes: using the first camera 50 to take a first image of the cover plate 1 in the first loading component 30; using the second camera 33 of the first loading component 30 to take a second image of the adapter plate pole 4 at the assembly position; performing position deviation correction and compensation on the first loading component 30 through the first image and the second image to accurately align the cover plate 1 with the adapter plate pole 4.

[0074] In this embodiment, during the process of the second feeding component 40 transporting the pole column component 2 from the feeding position to the assembling position, the feeding method further includes: using the third camera 60 to capture a third image of the pole column component 2 in the second feeding component 40; using the fourth camera 43 of the second feeding component 40 to capture a fourth image of the adapter plate pole column 4 after being assembled with the cover plate 1 at the assembling position; performing position deviation correction and compensation on the second feeding component 40 through the third image and the fourth image, so that the pole column component 2 is accurately aligned with the cover plate 1 and the adapter plate pole column 4.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: By providing a cover plate feeding device including a cover plate transfer member 10, a first feeding component 30, and a second feeding component 40, the cover plate transfer member 10 includes a first grasping mechanism 11 and a second grasping mechanism 12, which are used to respectively grasp and fix the pole column component 2 and the cover plate 1 and transport them to the feeding position. The first feeding component 30 is used to transport the cover plate 1 from the feeding position to the assembling position, and the second feeding component 40 is used to transport the pole column component 2 from the feeding position to the assembling position. In this way, by setting the cover plate transfer member 10 to successively grasp and fix the pole column component 2 and the cover plate 1 and transport them to the feeding position, the simultaneous transportation of the entire cover plate by a single transfer component in one trip is realized, avoiding multiple transfer components being respectively used to transfer the pole column component 2 and the cover plate 1, thereby reducing the position errors generated by the separate operation of multiple transfer components, enabling the pole column component 2 and the cover plate 1 at the feeding position to be in an accurate relative position, ultimately reducing the assembly tolerance between the pole column component 2 and the cover plate 1, ensuring the yield rate of the cover plate assembly. Further, by using two feeding components to respectively transport the cover plate 1 and the pole column component 2, the separate feeding of the cover plate 1 and the pole column component 2 is realized, reducing the feeding and assembling difficulty, also reducing the accumulation of assembly tolerance between the cover plate 1 and the pole column component 2, ensuring the coaxiality between the pole column component 2 and the cover plate 1, and enabling the cover plate to have a high assembly yield rate.
