[0002] With continuous social development and technological progress, automated production has become a development trend, gradually replacing traditional manual labor and injecting new impetus into the sustainable development of enterprises.

[0003] like Figure 1 As shown, the battery cell 10 is housed inside the steel shell 11 and adheres to the inner wall of the steel shell 11. In the actual production process, the battery cell 10 is first wound into a ring shape, and then the ring-shaped battery cell 10 is inserted into the steel shell 11.

[0004] During the process of inserting the battery cell 10 into the steel shell 11, the vertical positioning deviation between the battery cell 10 and the steel shell 11 causes assembly interference when the battery cell 10 is inserted into the steel shell 11. This results in defects such as deformation, scratches, cracks, and skewing on the side of the battery cell 10, which can lead to short circuits and performance failures, seriously affecting the product yield and increasing rework costs. Therefore, there is an urgent need for a device that can accurately align and effectively guide the battery cell 10 to be smoothly inserted into the steel shell 11 to solve the above problems.

[0011] Preferably, a first mounting plate is installed at the end of the vertical cylinder, and a lateral adjustment component is installed on the first mounting plate. The lateral adjustment component is connected to the housing positioning block and is used to adjust the lateral position of the housing positioning block. A longitudinal adjustment component is installed on the lateral adjustment component, and a housing positioning block is installed on the longitudinal adjustment component. The longitudinal position of the housing positioning block is adjusted precisely through the coordinated operation of the lateral adjustment component and the longitudinal adjustment component.

[0012] Preferably, the conveying fixture includes a placement plate, on which a positioning component for positioning the steel shell is mounted. The positioning component includes a first positioning block disposed on one side of the steel shell and a second positioning block disposed on the other side of the steel shell. The steel shell is placed on the first positioning block, and a positioning groove for positioning one side of the steel shell is provided on its side. The second positioning block is provided with an arc-shaped groove for positioning the other side of the steel shell.

[0013] Preferably, the first positioning block is provided with a plurality of positioning holes, and the housing positioning block is equipped with a positioning pin. When the vertical cylinder drives the housing positioning block to approach the steel shell, the positioning pin is inserted into the positioning hole to position the conveying fixture.

[0014] Preferably, the second positioning block reciprocates longitudinally relative to the steel shell, moving closer to or away from the steel shell; a second longitudinal guide rail is installed between the placement plate and the second positioning block, the second positioning block is sleeved on the second longitudinal guide rail and moves longitudinally along the second longitudinal guide rail, and the second positioning block is driven by a longitudinal driving member, which drives the second positioning block to move closer to or away from the steel shell along the second longitudinal guide rail.

[0015] Preferably, a third mounting block is installed at the end of the second longitudinal guide rail away from the first positioning block. An elastic element, which is a spring, is installed between the third mounting block and the second positioning block. The third mounting block has a first mounting hole, and the second positioning block has a second mounting hole. One end of the elastic element is inserted into the first mounting hole, and the other end is inserted into the second mounting hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

Operation process of this utility model: First, the steel shell is placed on the conveying fixture, which conveys the steel shell to the lower part of the first through hole, and the first through hole and the steel shell are aligned vertically; Second, the vertical drive unit drives the shell positioning block to move closer to the steel shell, so that the steel shell contacts the first through hole; Specifically, the lower part of the first through hole contacts the upper part of the steel shell; Finally, the robot picks up the battery cell, moves it above the first through hole, and drives the battery cell to move downward, so that it is vertically inserted into the steel shell along the first through hole.

[0019] 2. This utility model uses a conveying fixture to transport the steel shell to the lower part of the first through hole. The vertical drive unit drives the shell positioning block to approach the steel shell, so that the first through hole and the steel shell are aligned and in contact with each other, realizing a seamless connection between the lower part of the first through hole and the upper part of the steel shell.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are one embodiment of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 11 This utility model provides a lithium battery cell casing device.

[0037] The battery cell insertion device comprises multiple parts, including an upper station, a self-station, an assembly line, a conveyor fixture 3, and a robotic arm. The upper station is used to place the steel shell 11 on the conveyor fixture 3 and transport it by the assembly line to its own station, which is below the first through hole 21. The robotic arm picks up the battery cell 10 and moves it so that the battery cell 10 is above the first through hole 21. Driven by the robotic arm, the battery cell 10 is vertically inserted into the steel shell 11.

[0038] like Figure 2 As shown, the self-working station includes a mounting bracket 1, and a housing positioning block 2 is installed on one side of the mounting bracket 1. In this embodiment, as... Figure 2 As shown, the housing positioning block 2 is installed on the right side of the mounting bracket 1, and the housing positioning block 2 has a first through hole 21. The first through hole 21 is used for the power supply core 10 to pass through and accurately align with the opening end of the steel shell 11.

[0039] like Figure 2As shown, a conveying fixture 3 is installed on the right side of the mounting bracket 1. In this embodiment, the conveying fixture 3 moves laterally under the drive of the assembly line to transport the steel shell 11 from the upper station to a preset position. The preset position is directly below the first through hole 21, ensuring that the central axis of the steel shell 11 coincides with the axis of the first through hole 21. In other embodiments, the conveying fixture 3 can also use a turntable for arc-shaped conveying.

[0040] In this embodiment, a vertical drive component 5 is installed between the mounting bracket 1 and the housing positioning block 2. The vertical drive component 5 is connected to the housing positioning block 2 and drives the housing positioning block 2 to move vertically back and forth to adjust the relative height between the first through hole 21 and the steel shell 11 so that the steel shell 11 contacts the first through hole 21. Specifically, the lower part of the first through hole 21 is precisely aligned with and in contact with the opening end of the steel shell 11 to ensure that the battery cell 10 does not shift during insertion.

[0041] like Figure 2 As shown, a robotic arm is also installed on one side of the mounting bracket 1. The end of the robotic arm can cover the area above the housing positioning block 2, ensuring that the robotic arm can accurately transfer the battery cell 10 to the top of the first through hole 21. Specifically, the robotic arm uses multi-axis linkage control to vacuum-pick up the battery cell 10 and smoothly transfer it to the top of the first through hole 21. Then, it is precisely inserted vertically, guiding the battery cell 10 smoothly into the steel housing 11 along the first through hole 21, thus realizing the battery cell 10 entering the housing. After completing the entire housing insertion action, the robotic arm automatically resets, waiting for the next cycle. At the same time, the conveying fixture 3 continues to move the steel housing 11 with the battery cell 10 inserted along the production line to the next station for subsequent processing, thereby realizing continuous and automated production.

[0042] The cell insertion device, through the cooperation of the insertion positioning block 2 and the vertical drive component 5, effectively improves the alignment accuracy and stability of the cell insertion, reduces the assembly defect rate, and is suitable for lithium battery production lines with high efficiency and high consistency requirements.

[0043] Furthermore, to further increase positioning accuracy and extend the service life of the housing positioning block 2, a replaceable positioning sleeve 22 is installed inside the first through hole 21. When wear necessitates replacement, only the positioning sleeve 22 needs to be replaced, without replacing the entire housing positioning block 2, thus reducing maintenance costs and downtime. When adapting to different battery cell 10 specifications, simply replacing the positioning sleeve 22 with one matching the corresponding battery cell 10 size allows for quick equipment switching, adapting to the assembly requirements of different battery cell 10 models and significantly improving the production line's flexible production capabilities.

[0044] Furthermore, the positioning sleeve 22 can also be made of a highly wear-resistant material with a smooth inner wall and self-lubricating properties, which effectively reduces the frictional resistance when the battery cell 10 is inserted and avoids damage to the surface of the battery cell.

[0045] Furthermore, to facilitate the replacement of the positioning sleeve 22 and ensure a stable connection, in this embodiment, the positioning sleeve 22 is provided with fixing grooves 24 on both sides, and fixing bolts 25 are installed on both sides of the housing positioning block 2. The ends of the fixing bolts 25 pass through the housing positioning block 2 and are inserted into the fixing grooves 24 to fix the positioning sleeve 22 to the housing positioning block 2. With this structural design, the positioning sleeve 22 can be replaced without the use of complicated tools; simply loosening the fixing bolts 25 is sufficient, making the operation simple and quick.

[0046] In other embodiments, the housing positioning block 2 is provided with a quick locking mechanism, which can be used to assemble or disassemble the positioning sleeve 22 by rotating or pressing, without the need for additional tools.

[0047] To further increase the positioning accuracy between the positioning sleeve 22 and the steel shell 11, the positioning sleeve 22 is provided with a second through hole 23 that is adapted to the battery cell 10; the second through hole 23 is used to guide the battery cell 10 to be accurately inserted into the steel shell 11.

[0048] Furthermore, a first inclined guide surface 231 is provided on the upper part of the second through hole 23. The first inclined guide surface 231 is used to guide the lower part of the battery cell 10 into the second through hole 23. The setting of the first inclined guide surface 231 effectively compensates for the slight offset when the battery cell 10 is inserted. At the same time, the smooth transition design of the first inclined guide surface 231 reduces the frictional resistance when the battery cell 10 is inserted, avoids scratching the battery cell 10 due to excessive friction, and improves the smoothness of the insertion process. In addition, a second inclined guide surface 232 is provided on the lower part of the second through hole 23. The second inclined guide surface 232 is used to guide the upper part of the steel shell 11 into the second through hole 23. This ensures that the steel shell 11 achieves precise guidance and smooth transition when it enters the lower part of the second through hole 23, effectively improving the positioning accuracy and assembly stability of the steel shell 11, compensating for the offset or error of the steel shell 11 during the transportation process, thereby ensuring the coaxiality of the battery cell 10 and the steel shell 11 and improving the assembly yield.

[0049] The second inclined guide surface 232 works in conjunction with the first inclined guide surface 231 to form a bidirectional guide structure, which enables the battery cell and the steel shell to automatically correct their positions during the docking process, further reducing alignment errors.

[0050] Furthermore, the upper part of the second inclined guide surface 232 is also provided with a limiting groove 233, which is used to limit the upper part of the steel shell 11; limiting the insertion depth of the steel shell 11 into the positioning sleeve 22, so as to achieve higher docking accuracy and consistency.

[0051] The diameter of the limiting groove 233 matches the wall thickness of the steel shell 11, ensuring mutual cooperation during positioning. This prevents the steel shell 11 from becoming loose and avoids difficulty in inserting the steel shell 11 due to insufficient gap.

[0052] The design of the second inclined guide surface 232 and the limiting groove 233 allows the steel shell 11 to be guided to the predetermined position of the limiting groove 233 through the adaptive adjustment function of the inclined opening, so as to achieve rapid positioning and stable engagement, compensate for the positional error of the steel shell 11 during the transportation process, and control the coaxiality error within a very small range. This ensures that the battery cell 10 is accurately aligned with the steel shell 11 when it is inserted, effectively avoiding assembly damage or short circuit risk caused by eccentricity.

[0053] like Figure 2 As shown, in this embodiment, the vertical drive component 5 is a vertical cylinder. The left side of the vertical cylinder is fixedly connected to the mounting bracket 1 to achieve stable support and fixation of the vertical cylinder. The end of its piston rod is connected to the housing positioning block 2 for transmission, driving the housing positioning block 2 to move vertically back and forth; realizing the precise lifting and lowering action of the housing positioning block 2 in the vertical direction, inserting the lower part of the second through hole 23 into the upper part of the steel shell 11 until the upper part of the steel shell 11 is completely locked by the limiting groove 233, ensuring that the steel shell 11 is accurately positioned.

[0054] During use or equipment assembly, the position of the housing positioning block 2 may shift. Therefore, it is necessary to adjust the position of the housing positioning block 2. The horizontal and vertical positions of the housing positioning block 2 are finely adjusted by the adjustment mechanism to ensure that the second through hole 23 is always highly aligned with the central axis of the battery cell 10 and the steel shell 11.

[0055] Specifically, a first mounting plate 51 is installed at the end of the vertical cylinder. The first mounting plate 51 is fixedly connected to the piston rod. A lateral adjustment component 88 is installed on the first mounting plate 51. The lateral adjustment component 88 is pulsatorically connected to the housing positioning block 2 and is used to adjust the lateral position of the housing positioning block 2. A longitudinal adjustment component 89 is installed on the lateral adjustment component 88. The housing positioning block 2 is installed on the longitudinal adjustment component 89 and is used to adjust the longitudinal position of the housing positioning block 2. Through the coordinated cooperation of the lateral adjustment component 88 and the longitudinal adjustment component 89, the lateral and longitudinal positions of the housing positioning block 2 are precisely adjusted.

[0056] The lateral adjustment assembly 88 includes a lateral guide rail 52 mounted on a first mounting plate 51, and a lateral slider 53 sleeved on the lateral guide rail 52. The lateral slider 53 moves laterally along the lateral guide rail 52. In order to adjust and fix the position of the lateral slider 53, a first mounting block 81 is mounted on one side of the first mounting plate 51. A lateral adjustment screw 82 is mounted on the first mounting block 81. The lateral adjustment screw 82 passes through the first mounting block 81 and is threadedly connected to the lateral slider 53.

[0057] Furthermore, similarly, longitudinal adjustment is also possible. The longitudinal adjustment component 89 includes a first longitudinal guide rail 55 mounted on the transverse slider 53. A longitudinal slider 56 is fitted onto the first longitudinal guide rail 55, and a housing positioning block 2 is mounted on the longitudinal slider 56. The housing positioning block 2 moves longitudinally along the first longitudinal guide rail 55 to achieve precise adjustment of the longitudinal position. A second mounting block 83 is provided on one side of the transverse slider 53. A longitudinal adjustment screw 84 is mounted on the second mounting block 83. The longitudinal adjustment screw 84 passes through the second mounting block 83 and is threadedly connected to the longitudinal slider 56. By rotating the longitudinal adjustment screw 84, the longitudinal slider 56 can be driven to move smoothly along the first longitudinal guide rail 55, thereby fine-tuning the longitudinal position of the housing positioning block 2 to ensure that the center of the second through hole 23 is highly aligned with the axis of the steel shell 11, improving assembly accuracy and stability.

[0058] By coordinating the lateral adjusting screw 82 and the longitudinal adjusting screw 84, the housing positioning block 2 can be precisely adjusted laterally and longitudinally in the horizontal plane, effectively compensating for assembly errors and equipment operating errors. Simultaneously, the lateral guide rail 52 and the first longitudinal guide rail 55 are arranged perpendicularly to each other, forming a high-precision two-dimensional adjustment mechanism to ensure that the housing positioning block 2 moves smoothly and without wobbling during adjustment.

[0059] like Figure 9 and Figure 10 As shown, the conveying fixture 3 includes a placement plate 31, on which a positioning component 4 for positioning the steel shell 11 is mounted. The positioning component 4 stably limits the steel shell 11 to the middle, which facilitates the conveying of the conveying fixture 3 and subsequent precise docking.

[0060] The positioning component 4 includes a first positioning block 41 disposed on one side of the steel shell 11 and a second positioning block 42 disposed on the other side of the steel shell 11. The steel shell 11 is placed on the first positioning block 41, and a positioning groove 411 for positioning one side of the steel shell 11 is provided on its side. In this embodiment, the positioning groove 411 is V-shaped. The second positioning block 42 is provided with an arc-shaped groove 421 for positioning the other side of the steel shell 11. The positioning groove 411 and the arc-shaped groove 421 cooperate to effectively clamp the steel shell 11, ensuring that the steel shell does not shift or shake during transportation.

[0061] In order to accurately position the conveying fixture 3 before it connects with the steel shell 11 through the second through hole 23, and to accurately align the relative position between the conveying fixture 3 and the shell positioning block 2, in this embodiment, the first positioning block 41 is provided with a plurality of positioning round holes 412, and the shell positioning block 2 is equipped with positioning pins 26. When the vertical cylinder drives the shell positioning block 2 to approach the steel shell 11, the positioning pins 26 are inserted into the positioning round holes 412 to position the conveying fixture 3.

[0062] The cooperation between the positioning pin 26 and the positioning hole 412 enables high-precision alignment between the conveying fixture 3 and the housing positioning block 2, providing a reliable reference for the subsequent alignment between the second through hole 23 and the steel shell 11, and significantly reducing the risk of misalignment during the docking process; after the positioning pin 26 is inserted into the positioning hole 412, the conveying fixture 3 is automatically locked in a precise position and cannot produce any displacement, ensuring that the subsequent docking of the steel shell 11 and the second through hole 23 is completely fitted.

[0063] In this embodiment, there are two positioning pins 26, which are located at the lower part of the housing positioning block 2. The positioning holes 412 are also located at the corresponding positions of the first positioning block 41. The two sets of positioning pins and positioning holes correspond one-to-one, thereby improving the positioning accuracy.

[0064] In this embodiment, the second positioning block 42 reciprocates longitudinally relative to the steel shell 11, moving closer to or away from the steel shell 11. When the second positioning block 42 moves closer to the steel shell 11, it presses the steel shell 11 into the positioning groove 411 of the first positioning block 41, thereby achieving bidirectional limiting and stable clamping of the steel shell 11. When the second positioning block 42 moves away from the steel shell 11, it facilitates the rapid insertion or removal of the steel shell 11, improving loading and unloading efficiency. The reciprocating motion can be achieved by driving a horizontal cylinder, which provides rapid response and stable operation.

[0065] Furthermore, in order to ensure that the second positioning block 42 remains stable during longitudinal movement, a second longitudinal guide rail 43 is installed between the placement plate 31 and the second positioning block 42. The second positioning block 42 is sleeved on the second longitudinal guide rail 43 and moves longitudinally along the second longitudinal guide rail 43, effectively avoiding movement deviation or jamming, and ensuring the repeatability and reliability of the clamping action.

[0066] Furthermore, the second positioning block 42 is connected to a longitudinal driving component, which is a horizontal cylinder, to drive the second positioning block 42 to move closer to or away from the steel shell 11 along the second longitudinal guide rail 43.

[0067] In the above embodiment, the horizontal cylinder can be installed on one side of the second positioning block 42. The piston rod of the horizontal cylinder is connected to the second positioning block 42. Through the telescopic movement, the second positioning block 42 is driven to slide smoothly along the second longitudinal guide rail 43. When the horizontal cylinder extends, it drives the second positioning block 42 to move towards the steel shell 11 and firmly presses it into the positioning groove 411, so as to achieve accurate positioning and stable clamping of the steel shell 11. When the horizontal cylinder retracts, the second positioning block 42 moves away from the steel shell 11, releasing the clamping force and facilitating the placement of the steel shell 11.

[0068] In another embodiment, the horizontal cylinder is not mounted on the conveying fixture 3, but is mounted on the upper work station, and the steel shell 11 is placed and pressed by the elastic element 45.

[0069] Specifically, a third mounting block 44 is installed at the end of the second longitudinal guide rail 43 away from the first positioning block 41. An elastic element 45, which is a spring, is installed between the third mounting block 44 and the second positioning block 42. The third mounting block 44 has a first mounting hole 46, and the second positioning block 42 has a second mounting hole 47. One end of the elastic element 45 is inserted into the first mounting hole 46, and the other end is inserted into the second mounting hole 47. By pre-compressing the elastic element 45, a continuous clamping force is provided, driving the second positioning block 42 to move closer to the steel shell 11 along the second longitudinal guide rail 43, tightly pressing the steel shell 11 into the positioning groove 411 of the first positioning block 41, thus achieving adaptive clamping. When the steel shell 11 needs to be inserted or removed, the external force overcomes the elastic force of the elastic element 45, and the longitudinal drive member drives the second positioning block 42 to move away from the steel shell 11 along the second longitudinal guide rail 43.

[0070] The longitudinal drive component is a horizontal cylinder, installed at the upper workstation, and is connected to the second positioning block 42 via a drive rod 48. In this embodiment, the drive rod 48 is a T-shaped rod, with one end passing through the first positioning block 41 and the other end positioned on one side of the second positioning block 42. When the horizontal cylinder extends, the drive rod 48 pushes the second positioning block 42 along the second longitudinal guide rail 43 away from the steel shell 11, while overcoming the elastic force of the elastic element 45, providing sufficient space for the placement of the steel shell 11. When the horizontal cylinder retracts, the elastic element 45 drives the second positioning block 42 to automatically reset along the second longitudinal guide rail 43, pressing the steel shell 11 back into the positioning groove 411, and also pushing one end of the drive rod 48 out of the outside of the first positioning block 41, ensuring a compact structure and smooth operation.

[0071] like Figure 2As shown, the robotic arm is a multi-axis robotic arm, which can be an existing four-axis robotic arm, a six-axis robotic arm, or a multi-axis linkage mechanical structure assembled from modules; the end of the multi-axis robotic arm is equipped with a vacuum suction rod 61, which adsorbs the upper part of the battery cell 10 to pick up the battery cell 10 and accurately transfers the battery cell 10 to the top of the second through hole 23, and drives the vacuum suction rod 61 and the battery cell 10 to move downward, so that the battery cell 10 is vertically inserted into the steel shell 11.

[0072] The operation steps of the battery cell insertion device are as follows:

[0073] Step S1: The steel shell 11 is loaded at the upper station. The horizontal cylinder extends and the drive rod 48 pushes the second positioning block 42 to move away from the steel shell 11 along the second longitudinal guide rail 43. At the same time, it overcomes the elastic force of the elastic element 45, provides sufficient space for the placement of the steel shell 11, and places the steel shell 11 on the first positioning block 41.

[0074] Step S2: When the horizontal cylinder retracts, the elastic element 45 drives the second positioning block 42 to automatically reset along the second longitudinal guide rail 43, pressing the steel shell 11 back into the positioning groove 411, and also pushing one end of the drive rod 48 out of the outside of the first positioning block 41.

[0075] The positioning groove 411 cooperates with the arc-shaped groove 421 to effectively clamp the steel shell 11 and adapt to the positioning requirements of steel shells 11 with different diameter specifications, ensuring that the steel shell does not shift or shake during the transportation process.

[0076] Step S3: The conveying fixture 3 moves laterally under the drive of the production line, conveying the steel shell 11 from the upper station to directly below the first through hole 21, ensuring that the central axis of the steel shell 11 coincides with the axis of the first through hole 21;

[0077] Step S4: When the vertical cylinder drives the housing positioning block 2 to approach the steel housing 11, firstly, the positioning pin 26 is inserted into the positioning round hole 412 to position the conveying fixture 3; secondly, the upper part of the steel housing 11 enters the second inclined guide surface 232 and is guided by the second inclined guide surface 232; finally, the upper part of the steel housing 11 is completely engaged by the limiting groove 233.

[0078] Step S5: The vacuum suction rod 61 at the end of the robotic arm adsorbs the upper part of the battery cell 10, thereby picking up the battery cell 10; the robotic arm drives the vacuum suction rod 61 and the battery cell 10 to be precisely transferred above the second through hole 23, and drives the vacuum suction rod 61 and the battery cell 10 to move downwards, so that the lower part of the battery cell 10 is inserted into the first inclined guide surface 231, which effectively compensates for the slight offset when the battery cell 10 is inserted; the battery cell 10 passes vertically downwards through the second through hole 23 until it is inserted into the steel shell 11, thereby completing the entire process of inserting the battery cell into the shell.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
