Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of battery manufacturing, and particularly to a core housing inserting device, a battery cell assembly device and a core assembly method. Background Art

[0002] Energy conservation and emission reduction are the keys to the sustainable development of the automotive industry. Electric vehicles have become an important part of the sustainable development of the automotive industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development.

[0003] With the development of battery technology, not only battery materials but also battery manufacturing processes have become key factors restricting the performance of batteries. The applicant has found in research that in existing battery manufacturing processes, when assembling a core and a housing, problems such as damage to the core or the housing often occur. Summary of the Invention

[0004] In view of the above problems, embodiments of the present application provide a core housing inserting device, a battery cell assembly device and a core assembly method to solve the above problems existing in the prior art.

[0005] On the one hand, an embodiment of the present application provides a core housing inserting device, including: a main power mechanism, a housing fixing mechanism, a housing inserting mechanism and a core fixing mechanism; the core fixing mechanism is used to fix the core; the housing fixing mechanism is arranged on one side of the housing inserting mechanism and is used to fix the housing and drive the housing to move; the housing inserting mechanism is located between the housing fixing mechanism and the core fixing mechanism. The housing inserting mechanism includes a housing inserting mechanism body, and an XY floating slider is arranged on one side of the housing inserting mechanism body. One end of the XY floating slider is connected to the main power mechanism, and the other end is connected to the housing inserting mechanism body, and is used to drive the housing inserting mechanism body to freely slide relative to the main power mechanism, so as to adjust the relative positions of the housing and the core; the main power mechanism drives the housing fixing mechanism and the housing inserting mechanism to move, and sleeving the housing outside the core.

[0006] By setting the XY floating slider in the embodiment of the present application, the housing inserting mechanism can float relative to the main power mechanism, so as to adjust the relative positions of the core and the housing, enabling the core and the housing to be adaptively aligned, and avoiding the difficulties in housing insertion and damage to the core or the housing caused by the position error between the core and the housing.

[0007] In some embodiments, the XY floating slider includes an X-axis floating slider and a Y-axis floating slider; the X-axis floating slider is used to make the housing inserting mechanism body move relative to the main power mechanism in a first direction; the Y-axis floating slider is used to make the housing inserting mechanism body move relative to the main power mechanism in a second direction; the first direction and the second direction are perpendicular to each other.

[0008] In this way, the relative movement of the case-in mechanism and the driving mechanism in the first direction and the second direction is realized, and the positions of the battery cell and the case can be conveniently and flexibly adjusted adaptively.

[0009] In some embodiments, the case-in mechanism further includes a reset mechanism. One end of the reset mechanism is connected to the case-in mechanism body, and the other end is connected to the driving mechanism, which is used to relatively move the case-in mechanism and the driving mechanism to reset the case-in mechanism.

[0010] Through the reset operation of the reset mechanism, after the case-in operation of each battery cell is completed, the case-in mechanism can be reset, avoiding the expansion of the position deviation between the case and the battery cell and improving the assembly efficiency of the battery cell and the case.

[0011] In some embodiments, the reset mechanism includes a reset clamping mechanism. The reset clamping mechanism is arranged on the case-in mechanism body, and a jaw cylinder is arranged at the bottom of the reset clamping mechanism;

[0012] A driving mechanism connecting shaft is arranged between the reset clamping mechanisms. The driving mechanism is connected to the case-in mechanism through the driving mechanism connecting shaft;

[0013] When the reset clamping mechanism clamps the driving mechanism connecting shaft, the jaw cylinder drives the case-in mechanism body to move relative to the driving mechanism to reset the case-in mechanism body.

[0014] By arranging the reset clamping mechanism, the case-in mechanism can be conveniently reset, with a simple structure and greatly improving the efficiency of the battery cell entering the case.

[0015] In some embodiments, the reset mechanism includes a first reset clamping mechanism and a second reset clamping mechanism. The driving mechanism connecting shaft is arranged between the first reset clamping mechanism and the second reset clamping mechanism. One end of the first reset clamping mechanism and the second reset clamping mechanism is fixed on the case-in mechanism body, and when the other ends of the first reset clamping mechanism and the second reset clamping mechanism slide, they clamp the driving mechanism connecting shaft, and then the jaw cylinder drives the case-in mechanism body to move relative to the driving mechanism.

[0016] By arranging the first reset clamping mechanism and the second reset clamping mechanism, it is convenient to clamp the driving mechanism connecting shaft when sliding, so as to drive the case-in mechanism body to move relative to the driving mechanism through the jaw cylinder for resetting.

[0017] In some embodiments, the opposite ends of the first reset clamping mechanism and the second reset clamping mechanism are in a V-shaped groove shape.

[0018] By setting the opposite ends of the first reset clamping mechanism and the second reset clamping mechanism to be V-shaped groove-like, when the case loading mechanism is offset, the V-shaped groove-like ends will generate pressure on the connecting shaft of the main power mechanism. The pressure causes the case loading mechanism to float and automatically adjust its own position for reset.

[0019] In some embodiments, the battery cell fixing mechanism and the housing fixing mechanism are arranged along the vertical direction.

[0020] By arranging the battery cell fixing mechanism and the housing fixing mechanism along the vertical direction, the battery cell and the housing can be assembled into the case in an upright manner, that is, in a vertical case loading manner, thus avoiding the problem that in the traditional horizontal case loading manner, the battery cell is likely to shift downward during the movement due to gravity and is difficult to be pushed into the case.

[0021] In some embodiments, the battery cell fixing mechanism is located below the housing fixing mechanism.

[0022] By arranging the battery cell fixing mechanism below the housing fixing mechanism, the battery cell and the housing are always in an upright state during the case loading assembly process, which is an inverted case loading manner, and can avoid the problem that in the traditional horizontal case loading manner, the battery cell is likely to shift downward during the movement due to gravity and is difficult to be pushed into the case.

[0023] In some embodiments, a mold splitting mechanism is movably arranged on one side of the case loading mechanism body. The mold splitting mechanism encloses to form a receiving cavity, and the receiving cavity is hollow for positioning the battery cell.

[0024] The battery cell fixing mechanism drives the battery cell to move so that the battery cell is located in the receiving cavity.

[0025] In the embodiment of the present application, by providing the receiving cavity, the preliminary alignment of the battery cell and the housing can be conveniently achieved, the error during the battery cell case loading is reduced, and the scratching of the battery cell film by the housing inlet is avoided, thus preventing damage to the battery cell film.

[0026] In some embodiments, an inlet diaphragm is arranged at a position corresponding to the edge of the receiving cavity on the mold splitting mechanism; the inlet diaphragm extends towards the middle of the receiving cavity for isolating the housing from the battery cell.

[0027] By providing the inlet diaphragm, the housing and the battery cell first come into contact with the inlet diaphragm, and the inlet diaphragm forms a protection for the film on the surface of the battery cell to avoid scratching the battery cell by the shell opening.

[0028] In some embodiments, a guiding slope is arranged at a position corresponding to the edge of the receiving cavity on the mold splitting mechanism, and the guiding slope is used to guide the battery cell to be received in the receiving cavity.

[0029] By setting a guiding ramp, the case loading mechanism drives the mold splitting connecting plate to move, thereby adaptively adjusting the position of the mold splitting connecting plate according to the pressure, and further adjusting the position of the accommodating cavity, so that the battery cell can be conveniently accommodated in the accommodating cavity, achieving alignment with the case, and thus avoiding scratches on the film covering the battery cell at the opening of the case when the battery cell and the case cannot be aligned.

[0030] In some embodiments, a flaring mechanism is provided on the body of the case loading mechanism on the side facing the case fixing mechanism; the flaring mechanism is arranged corresponding to the accommodating cavity and is used for flaring the case accommodated in the accommodating cavity.

[0031] By setting the flaring mechanism, a better flaring effect can be achieved, enabling the battery cell to enter the case more conveniently.

[0032] In some embodiments, the flaring mechanism includes a flaring suction cup, and the flaring suction cup is used for adsorbing the side wall at the opening of the case.

[0033] By setting the flaring suction cup, the outer wall of the case can be conveniently adsorbed and connected and released, with a simple structure and the ability to be repeatedly operated for a long time.

[0034] On the other hand, the embodiment of the present application also provides a battery cell assembly device, including the above-mentioned battery cell case loading device.

[0035] On the other hand, the embodiment of the present application also proposes a battery cell assembly method, including:

[0036] Providing a case and a battery cell;

[0037] Moving the case and the battery cell to the accommodating cavity respectively and adjusting the relative positions of the battery cell and the case;

[0038] Sheathing the case outside the battery cell.

[0039] Through the battery cell assembly method provided by the embodiment of the present application, the relative positions of the battery cell and the case can be adjusted, enabling the battery cell and the case to be adaptively aligned, facilitating the entry of the battery cell into the case, and avoiding damage to the battery cell or the case caused by the position error between the battery cell and the case.

[0040] In some embodiments, in the step of providing the case and the battery cell, the case and the battery cell are arranged vertically.

[0041] By arranging the battery cell and the case vertically, the battery cell and the case can be assembled into the case in an upright manner, that is, in a vertical case loading manner, thus avoiding the problem that in the traditional horizontal case loading manner, the battery cell is likely to shift downward during the movement and is difficult to be pushed into the case due to gravity.

[0042] In some embodiments, in the step of arranging the case and the battery cell vertically, the battery cell is located below the case.

[0043] By placing the battery cell below the housing, the battery cell and the housing are always in an upright state during the housing assembly process, which is an inverted housing method. This can avoid the problem that in the traditional horizontal housing method, due to gravity, the battery cell may shift downward during the movement and it is difficult to push it into the housing.

[0044] In some embodiments, the method further includes:

[0045] Resetting the accommodation cavity.

[0046] Through the reset operation, after the housing operation of each battery cell is completed, the device can be reset, avoiding the expansion of the position deviation between the housing and the battery cell, and improving the assembly efficiency of the battery cell and the housing.

[0047] In some embodiments, a guiding ramp is provided at the edge of the accommodation cavity;

[0048] The separately moving the housing and the battery cell into the accommodation cavity includes:

[0049] Moving the housing into the accommodation cavity;

[0050] Moving the battery cell to the position of the accommodation cavity, correcting the position of the accommodation cavity through the guiding ramp, and placing the battery cell in the accommodation cavity.

[0051] By providing the guiding ramp, when the battery cell abuts against the guiding ramp, a certain pressure can be generated on the accommodation cavity. Under the action of the pressure, the accommodation cavity actively adjusts its relative position with the battery cell, enabling the positions of the housing and the battery cell to be automatically aligned, avoiding the scraping of the battery cell by the housing due to the position deviation between the battery cell and the housing, and damaging the film covering of the battery cell.

[0052] In some embodiments, an insertion diaphragm is provided at the edge of the accommodation cavity;

[0053] The sleeving the housing outside the battery cell includes:

[0054] The housing abuts against the battery cell through the insertion diaphragm;

[0055] Sleeving the housing outside the battery cell;

[0056] When the housing moves to a preset position outside the battery cell, move the insertion diaphragm to both sides of the battery cell and draw the insertion diaphragm out of the housing.

[0057] By providing the insertion diaphragm, the housing and the battery cell are not in direct contact, avoiding the damage to the film covering of the battery cell by the housing, and playing a great role in protecting the battery cell.

[0087] At present, from the perspective of the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in many fields such as military equipment and aerospace. With the continuous expansion of the application fields of batteries, the market demand is also constantly increasing.

[0088] With the gradual popularization of batteries, the production and manufacturing process of batteries has become increasingly important. The production and manufacturing process level of batteries will seriously restrict the production efficiency of batteries on the one hand and affect the performance of batteries on the other hand. If the battery manufacturing process is not perfect, it will cause the reduction of the yield rate during the production and manufacturing process of batteries, or it will lead to defects in some aspects of the batteries, resulting in performance problems, and seriously affecting the service life of the batteries.

[0089] At present, the battery cell mainly includes a housing and a core component. The core component is arranged inside the housing. The housing is a component that forms the internal environment of the battery cell. Among them, the formed internal environment can be used to accommodate the core component, electrolyte, and other components. The housing has a structure with one end open and the inside hollow. The core is arranged inside the housing, and an end cap is covered on the opening of the housing. By covering the end cap on the opening at the opening, the internal environment of the battery cell is formed. Of course, the end cap and the housing can also be integrated. Specifically, the end cap and the housing can first form a common connection surface before other components enter the housing, and when it is necessary to encapsulate the inside of the housing, then cover the end cap on the housing. The housing can be of various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. Specifically, the shape of the housing can be determined according to the specific shape and size of the core component. The material of the housing can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. The embodiments of the present application do not make special restrictions on this.

[0090] The core component is the component that undergoes an electrochemical reaction in the battery cell. The housing can contain one or more core components. The core component is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and usually a separator is provided between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active substances constitute the main body of the core component, and the parts of the positive electrode sheet and the negative electrode sheet without active substances respectively constitute the electrode tabs. The positive electrode tab and the negative electrode tab can be located at one end of the main body together or at both ends of the main body respectively. During the formation process of the core component, when the positive electrode sheet, the negative electrode sheet, and the separator material are wound, it is necessary to inject electrolyte into the core component. The wound core component fully absorbs the injected electrolyte, so that the core component and the electrolyte can be fully mixed to achieve the best wetting effect. During the charge and discharge process of the battery, the positive active substance and the negative active substance react with the electrolyte, and the electrode tabs are connected to the electrode terminals to form a current loop.

[0091] The inventors of the present application have noticed that during the assembly process of lithium batteries, the assembly of the housing and the battery cell is of utmost importance. There are various ways to assemble the housing and the battery cell. The commonly adopted method in the industry is the horizontal shell insertion method, that is, the lying battery cell is pushed into the housing along the guide plate. The inventors of the present application have found that during the process of pushing the battery cell into the housing, the Mylar film wrapped around the outside of the battery cell will generate friction with the guide plate and the entrance of the housing, etc., resulting in scratches on the Mylar film. At the same time, the top cover of the battery cell will also rub against the guide plate, the entrance of the housing, etc., causing damage to the housing and the coating film. Further, during the process of pushing the battery cell into the housing, due to gravity, the battery cell will deviate downward to a certain extent during the movement, which will further cause a step between the entrance of the housing and the top cover, making it difficult to push the battery cell in. Moreover, due to the errors in the housing and battery cell materials, the current shell insertion method cannot be adaptively adjusted according to the corresponding errors, resulting in damage to the entrance of the housing and the top cover during the shell insertion process of the battery cell.

[0092] To solve the problem of the inability to insert the battery cell into the housing caused by the position offset between the housing and the battery cell, an apparatus for inserting a battery cell into a housing, a battery cell assembly apparatus, and a method proposed in an embodiment of the present application can make the insertion mechanism float relative to the main power mechanism by setting an XY floating slider, and can automatically adjust the relative positions of the battery cell and the housing, so that the battery cell and the housing can be adaptively aligned, avoiding the difficulty of inserting the housing due to the position error between the housing and the battery cell and the damage to the battery cell or the housing. Moreover, a reset mechanism is also provided, which can reset the insertion mechanism after the insertion operation of each battery cell is completed, avoiding the expansion of the position deviation between the housing and the battery cell, further ensuring the accuracy of the relative positions of the housing and the battery cell, and improving the assembly efficiency of the battery cell and the housing. Further, on the one hand, in an embodiment of the present application, a receiving cavity is also provided at the insertion mechanism, and the positions of the housing and the battery cell can be automatically corrected before the battery cell is inserted into the housing, ensuring the alignment of the battery cell and the housing. On the other hand, in order to enable the battery cell to quickly enter the receiving cavity, a guiding ramp is also provided at the edge of the receiving cavity to guide the battery cell into the receiving cavity. During the guiding process, if the battery cell and the housing are offset, the insertion mechanism can be floated by the XY floating slider, and a pressure in the adjustment direction can be generated during the contact and extrusion between the battery cell and the guiding ramp, thereby guiding the insertion mechanism to automatically adjust its own position and adaptively correct the deviation between the housing and the battery cell, so that the housing can accurately enter the receiving cavity, ensuring the alignment of the housing and the battery cell, and avoiding the damage to the battery cell film caused by inaccurate alignment during the insertion of the battery cell. In addition, in order to avoid the contact and friction between the battery cell and the entrance of the housing when the battery cell is inserted into the housing, which may cause damage to the battery cell film and the entrance of the housing, in an embodiment of the present application, an insertion diaphragm is also provided at the edge of the receiving cavity to isolate the housing and the battery cell, avoiding the housing entrance from scratching the battery cell film; in an embodiment of the present application, before the battery cell is inserted, the outer wall of the housing is expanded by a flaring mechanism to increase the entrance of the housing, so that the battery cell can be easily sleeved into the entrance of the housing.

[0093] To solve the above problems, an embodiment of the present application proposes an apparatus 1000 for inserting a battery cell into a housing, as Figure 1 and Figure 2 shown, Figure 1 which shows a perspective view of the apparatus 1000 for inserting a battery cell into a housing, Figure 2A side view of the battery cell casing device 1000 is shown. The device includes: a main power mechanism 100, a casing fixing mechanism 200, a casing inserting mechanism 300, and a battery cell fixing mechanism 400. The battery cell fixing mechanism 400 is used to fix the battery cell 600. The mechanisms cooperate with each other to sleuth the casing 500 outside the battery cell 600. The casing fixing mechanism 200 is arranged on one side of the casing inserting mechanism 300 and is fixedly connected to the casing inserting mechanism 300, and is used to fix the casing 500 and drive the casing 500 to move. The casing inserting mechanism 300 is located between the casing fixing mechanism 200 and the battery cell fixing mechanism 400 and is movably connected to the main power mechanism 100. The main power mechanism 100 drives the casing fixing mechanism 200 and the casing inserting mechanism 300 to move, and sleuths the casing 500 outside the battery cell 600. As Figure 3 shown, the casing inserting mechanism 300 includes a casing inserting mechanism body 301. In order to better align the battery cell 600 and the casing 500, an XY floating slider is arranged on one side of the casing inserting mechanism body 301. The XY floating slider has two ends that slide relative to each other. One end of the XY floating slider is connected to the main power mechanism 100, and the other end is connected to the casing inserting mechanism body 301, and is used to drive the casing inserting mechanism body 301 to freely slide relative to the main power mechanism 100. Since the battery cell 600 is stationary relative to the main power mechanism 100, the position of the casing inserting mechanism body 301 can be adjusted relative to the battery cell 600, thereby adjusting the relative position of the casing 500 and the battery cell 600.

[0094] Among them, the main power mechanism 100 is the main power mechanism of the battery cell casing device 1000. It is connected to the casing inserting mechanism 300 and drives the entire casing inserting mechanism 300 to move up and down. The casing fixing mechanism 200 is used to fix the casing 500 and drive the casing 500 to move. The casing fixing mechanism 200 can be fixedly connected to the casing inserting mechanism 300. When the main power mechanism 100 drives the casing inserting mechanism 300 to move, the casing fixing mechanism 200 can move together. The battery cell fixing mechanism 400 is located on the side of the casing inserting mechanism 300 away from the casing fixing mechanism 200, so that the casing inserting mechanism 300 is located between the casing fixing mechanism 200 and the battery cell fixing mechanism 400. In this way, the casing 500 and the battery cell 600 can be assembled by inserting the casing through the casing inserting mechanism 300.

[0095] For the battery cell casing device 1000 provided in this embodiment, the casing 500 is fixed by the casing fixing mechanism 200, and the battery cell 600 is fixed by the battery cell fixing mechanism 400. A casing inserting mechanism is arranged between the casing fixing mechanism 200 and the battery cell fixing mechanism 400, and is used to correct the position of the casing 500 according to the position of the battery cell 600, so that the battery cell 600 and the casing 500 can be well aligned, which is convenient for casing insertion assembly.

[0096] In some embodiments, the main power mechanism 100 is connected to the shelling mechanism 300 through the shelling mechanism connecting bracket 110. One end of the shelling mechanism connecting bracket 110 is fixed to the conveyor belt of the main power mechanism 100, and the other end is connected to the shelling mechanism 300 through the shelling mechanism connecting plate 120. The shelling mechanism connecting plate 120 is provided with shelling mechanism fixing holes 121, and is connected to the shelling mechanism 300 through the shelling mechanism fixing holes 121. The shelling mechanism 300 can move up and down integrally with the conveyor belt under the control of the main power mechanism 100. The shelling mechanism connecting bracket 110 can be a plate-shaped connecting member extending from the main body of the main power mechanism 100, or a structure of other shapes. The purpose is to enable the shelling mechanism 300 to be connected to the power mechanism of the main power mechanism 100 through the shelling mechanism connecting bracket 110, and to control the up and down movement of the shelling mechanism 300 through the main power mechanism 100.

[0097] As Figure 2 shown, the housing fixing mechanism 200 is used to fix the housing 500. When the housing conveying mechanism conveys the housing 500 to the housing fixing mechanism 200, the housing fixing mechanism 200 clamps the housing 500 through the housing clamping portion 220. The housing fixing mechanism 200 is fixedly connected to one side of the shelling mechanism 300 through the housing fixing mechanism bracket 210. As Figure 3 shown, a housing fixing mechanism fixing frame 360 is provided on the shelling mechanism 300. The housing fixing mechanism 200 is arranged together with the shelling mechanism 300 through the housing fixing mechanism bracket 210 and the housing fixing mechanism fixing frame 360. On the one hand, the housing fixing mechanism 200 can move up and down with the shelling mechanism 300 along with the main power mechanism 100. On the other hand, the battery cell housing device 1000 further includes a sub-power mechanism, and the housing fixing mechanism 200 freely adjusts the position of the housing 500 through the sub-power mechanism.

[0098] The battery cell fixing mechanism 400 is used to fix the battery cell 600. The battery cell fixing mechanism 400 can be arranged together with the main power mechanism 100, or can be arranged separately. The battery cell fixing mechanism 400 is usually arranged on a circular slide rail for circulating and transporting the battery cell 600, and transporting the battery cell 600 to be assembled to a position corresponding to the shelling mechanism 300. As Figure 1 and Figure 2 shown, the battery cell fixing mechanism 400 and the housing fixing mechanism 200 are arranged opposite to each other. When the battery cell is inserted into the housing, usually after the battery cell fixing mechanism 400 fixes the battery cell 600, the housing fixing mechanism 200 moves the housing 500 to sleuth the housing 500 outside the battery cell 600.

[0099] In some embodiments, the shelling mechanism 300 is located between the housing fixing mechanism 200 and the battery cell fixing mechanism 400, and is movably connected to the main power mechanism 100 through the main power mechanism connecting plate 3502. AsFigure 3 As shown, an XY floating slider is provided on one side of the shelling mechanism body 301. Through this XY floating slider, the shelling mechanism body 301 and the main power mechanism 100 can slide relatively freely in different directions. The sliding directions include a first direction and a second direction. Usually, the first direction and the second direction are perpendicular to each other.

[0100] Of course, in other embodiments, the angle between the first direction and the second direction can be set according to the situation.

[0101] In some embodiments, as Figure 3 shown, a plurality of XY floating sliders are provided on the shelling mechanism body 301, including a first XY floating slider 330, a second XY floating slider 331, a third XY floating slider 332, and a fourth XY floating slider 333, which are symmetrically arranged at different positions of the shelling mechanism body 301 with the center of the shelling mechanism body 301 as the symmetry point. By providing a plurality of XY floating sliders, the connection between the shelling mechanism 300 and the main power mechanism 100 can be made more stable and firm.

[0102] By providing the XY floating slider, the shelling mechanism 300 can float relative to the main power mechanism 100, so as to automatically adjust the position of the shelling mechanism 300 according to the position of the battery cell 600, enabling the battery cell 600 and the housing 500 to be adaptively aligned, and avoiding the difficulty of shelling caused by the position error between the housing 500 and the battery cell 600 and the damage to the battery cell 600 or the housing 500.

[0103] In some embodiments, the XY floating slider includes an X-axis floating slider and a Y-axis floating slider; the X-axis floating slider is used to make the shelling mechanism body 301 move relatively with the main power mechanism 100 in the first direction, as Figure 3 shown by the arrow X direction in Figure 3 ; the Y-axis floating slider is used to make the shelling mechanism body 301 move relatively with the main power mechanism 100 in the second direction, as

[0104] Figure 5This is a partially enlarged view of the XY floating slider proposed in the embodiments of the present application. Taking the third XY floating slider 332 as an example, it includes a first X-axis floating slider 3322, a second X-axis floating slider 3324, a first Y-axis floating slider 3326, and a second Y-axis floating slider 3328. The first X-axis floating slider 3322 and the second X-axis floating slider 3324 are arranged together and slide in the first direction; the first Y-axis floating slider 3326 and the second Y-axis floating slider 3328 are respectively arranged at both ends of the first X-axis floating slider 3322 and the second X-axis floating slider 3324 and slide in the second direction. Usually, the first direction and the second direction are perpendicular to each other. Of course, in other embodiments, the angle between the first direction and the second direction can be set according to the situation.

[0105] Specifically, the first X-axis floating slider 3322 is connected to the first X-axis floating slide rail 3323, the second X-axis floating slider 3324 is connected to the second X-axis floating slide rail 3325, and the first X-axis floating slide rail 3323 and the second X-axis floating slide rail 3325 are arranged in parallel side by side. The first Y-axis floating slider 3326 is connected to the first Y-axis floating slide rail 3327, the second Y-axis floating slider 3328 is connected to the second Y-axis floating slide rail 3329. The first Y-axis floating slide rail 3327 and the second Y-axis floating slide rail 3329 are respectively located at both ends of the first X-axis floating slide rail 3323 and the second X-axis floating slide rail 3325. The two ends of the whole of the first X-axis floating slider 3322, the first X-axis floating slide rail 3323, the second X-axis floating slider 3324, and the second X-axis floating slide rail 3325 are respectively supported on the first Y-axis floating slider 3326 and the second Y-axis floating slider 3328 by a connecting plate. As Figure 5 shown, the first Y-axis floating slide rail 3327 and the second Y-axis floating slide rail 3329 are fixedly connected to the main body 301 of the case-in mechanism, and the first X-axis floating slider 3322 and the second X-axis floating slider 3324 are fixedly connected to the main power mechanism 100. Referring to Figure 1 shown, the main power mechanism 100 is fixedly connected to the first X-axis floating slider 3322 and the second X-axis floating slider 3324 through the case-in mechanism connecting plate 120. A case-in mechanism fixing hole 121 is provided on the case-in mechanism connecting plate 120, and case-in mechanism connecting plate fixing holes 3321 are respectively provided on the first X-axis floating slider 3322 and the second X-axis floating slider 3324. The case-in mechanism connecting plate 120 is arranged on the first X-axis floating slider 3322 and the second X-axis floating slider 3324 by bolts or other means. In this way, the relative movement of the case-in mechanism 300 and the main power mechanism 100 in the first direction and the second direction is realized, the position of the case-in mechanism 300 can be freely adjusted, and the positions of the battery cell 600 and the housing 500 can be adaptively and flexibly adjusted conveniently.

[0106] In some embodiments, the housing insertion mechanism 300 further includes a reset mechanism 350. One end of the reset mechanism 350 is connected to the housing insertion mechanism body 301, and the other end is connected to the main power mechanism 100. The reset mechanism 350 is configured to relatively move the housing insertion mechanism 300 and the main power mechanism 100 to reset the housing insertion mechanism 300.

[0107] During the assembly process of the housing 500 and the battery cell 600, the relative positions between the housing insertion mechanism 300 and the main power mechanism 100 are adjusted, thereby adjusting the position of the housing 500. After the assembly of the housing 500 and the battery cell 600 is completed, the reset mechanism 350 needs to readjust the relative positions of the main power mechanism 100 and the housing insertion mechanism 300 to restore the housing insertion mechanism 300 to its initial position. Continuing to refer to Figure 3 , a reset mechanism 350 is provided on the housing insertion mechanism body 301. After the housing insertion mechanism 300 cooperates with the housing fixing mechanism 200 and the battery cell fixing mechanism 400 to complete the insertion of the battery cell 600 into the housing, the reset mechanism 350 resets the housing insertion mechanism 300 to make it located at its initial position again, facilitating subsequent insertion operations of the housing 500 and the battery cell 600. Specifically, the reset mechanism 350 has a relatively movable first end and a second end. The first end is fixedly provided on the housing insertion mechanism body 301, and the other end is fixedly connected to the main power mechanism 100. Since the housing insertion mechanism 300 is adjustable in position in a floating manner, when the reset mechanism 350 acts, it can drive the housing insertion mechanism body 301 to move relative to the main power mechanism 100, thereby adjusting the relative positions of the main power mechanism 100 and the housing insertion mechanism 300.

[0108] Through the reset operation of the reset mechanism 350, after the insertion operation of each battery cell is completed, the housing insertion mechanism 300 can be reset, avoiding the expansion of the position deviation between the housing 500 and the battery cell 600 and improving the assembly efficiency of the battery cell 600 and the housing 500.

[0109] Refer to Figure 7 , in some embodiments, the reset mechanism 350 includes a reset clamping mechanism which is provided on the housing insertion mechanism body 301. A main power mechanism connecting shaft 3501 is arranged between the reset clamping mechanisms. The main power mechanism 100 is connected to the housing insertion mechanism 300 through the main power mechanism connecting shaft 3501. Taking the main power mechanism 100 connecting shaft 3501 as a reference point, when the position of the housing insertion mechanism 300 deviates from the initial position, the reset clamping mechanism clamps the main power mechanism connecting shaft 3501, and at the same time, the reset clamping mechanism drives the housing insertion mechanism body 301 to move relative to the main power mechanism 100 to reset the housing insertion mechanism body 301.

[0110] As Figure 7As shown, it is a partially enlarged view of the reset mechanism 350. The reset mechanism 350 includes a first reset clamping mechanism 3503 and a second reset clamping mechanism 3504 which are oppositely arranged. A jaw cylinder 3505 is provided at the bottom of the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504. One end of the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504 is fixed on the main body 301 of the case loading mechanism. A driving force mechanism connecting shaft 3501 is arranged between the other end of the first reset clamping mechanism 3503 and the other end of the second reset clamping mechanism 3504. The driving force mechanism connecting shaft 3501 is connected to the driving force mechanism 100 through a driving force mechanism connecting plate 3502. Taking the driving force mechanism 100 connecting shaft 3501 as a reference point, when the position of the case loading mechanism 300 deviates from the initial position, one of the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504 will contact the driving force mechanism connecting shaft 3501 and generate pressure between them. At this time, the jaw cylinder 3505 drives the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504 to slide, so that the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504 clamp the driving force mechanism connecting shaft 3501. At the same time, the jaw cylinder 3505 moves and drives the main body 301 of the case loading mechanism to move relative to the driving force mechanism 100, realizing the reset of the case loading mechanism 300. By setting this reset clamping mechanism, the case loading mechanism 300 can be conveniently reset, with a simple structure and greatly improving the efficiency of the battery core case loading.

[0111] In some embodiments, the opposite ends of the first reset clamping mechanism 3503 and the second reset clamping mechanism 3504 in this application embodiment are in a V-shaped groove shape. When the case loading mechanism 300 is offset, the V-shaped groove-shaped ends will generate pressure relative to the driving force mechanism connecting shaft 3501, and the pressure causes the case loading mechanism 300 to float and automatically adjust its own position for reset.

[0112] In some embodiments, in order to avoid the problems of difficult case loading caused by the position offset due to the gravity of the housing 500 when the battery core is horizontally loaded into the case and the damage to the battery core film, a vertical case loading method is proposed, that is, the battery core 600 and the housing 500 are assembled into the case in an upright manner. Specifically, the battery core fixing mechanism 400 and the housing fixing mechanism 200 are arranged along the vertical direction. By arranging the battery core fixing mechanism 400 and the housing fixing mechanism 200 along the vertical direction, the battery core 600 and the housing 500 can be assembled into the case in an upright manner, that is, the vertical case loading method, thus avoiding the problems that the traditional horizontal case loading method may cause the battery core to move downward and be difficult to push into the case due to gravity and the damage to the battery core film.

[0113] In some embodiments, the battery cell fixing mechanism 400 is located below the housing fixing mechanism 200, so that during the process of assembling the battery cell 600 and the housing 500 into the housing, they are always in an upright state, and vertical housing assembly can be performed, avoiding the problems that in the traditional horizontal housing insertion method, the battery cell may move downward and be difficult to be pushed into the housing due to gravity, and the problem of damage to the battery cell film.

[0114] In some embodiments, a mold splitting mechanism is movably arranged on one side of the housing insertion mechanism body 301. The mold splitting mechanism encloses to form a receiving cavity 310. The receiving cavity 310 is hollow and is used for positioning the battery cell 600. The battery cell fixing mechanism 400 drives the battery cell 600 to move so that the battery cell 600 is located in the receiving cavity 310.

[0115] As Figure 3 and Figure 4 shown, Figure 3 is a perspective view of the housing insertion mechanism 300, Figure 4 and is a bottom view of the housing insertion mechanism 300. The housing insertion mechanism 300 includes a housing insertion mechanism body 301, and the housing insertion mechanism body 301 can be a fixing plate for carrying each component of the housing insertion mechanism 300. The housing insertion mechanism body 301 is divided into an upper surface and a lower surface. The upper surface is the side facing the housing fixing mechanism 200, and the lower surface is the side facing the battery cell fixing mechanism 400. As Figure 3 shown, the middle part of the housing insertion mechanism body 301 has a hollow structure, and the housing 500 and the battery cell 600 can be accommodated in this hollow structure to achieve docking.

[0116] At the edge of this hollow structure and on one side of the housing insertion mechanism body 301, a mold splitting mechanism is movably arranged, as Figure 4As shown, optionally, the mold splitting mechanism is disposed on the lower surface of the housing inserting mechanism body 301, facing one side of the battery cell fixing mechanism 400. Of course, it can also be disposed at other positions. The mold splitting mechanism includes a first mold splitting mechanism 340 and a second mold splitting mechanism 341. The two mold splitting mechanisms are oppositely disposed and can move towards or away from the housing inserting mechanism body 301 respectively. The first mold splitting mechanism 340 includes a first mold splitting connecting member 3401 and a first mold splitting connecting plate 3402. The second mold splitting mechanism 341 includes a second mold splitting connecting member 3411 and a second mold splitting connecting plate 3412. The first mold splitting connecting member 3401 and the second mold splitting connecting member 3411 are used to drive the first mold splitting connecting plate 3402 and the second mold splitting connecting plate 3412 to move respectively. On one side of the first mold splitting connecting plate 3402 and the second mold splitting connecting plate 3412, recessed structures are respectively provided. When the first mold splitting connecting plate 3402 and the second mold splitting connecting plate 3412 contact, the recessed structures on both sides enclose to form a receiving cavity 310 for receiving the housing 500 and the battery cell 600. When the first mold splitting connecting plate 3402 and the second mold splitting connecting plate 3412 move in opposite directions, the receiving cavity 310 is divided into two parts, so that the assembled battery cell 600 leaves the assembly station.

[0117] When inserting the battery cell into the housing, the battery cell fixing mechanism 400 first drives the battery cell 600 to move to a position below the receiving cavity 310 on the housing inserting mechanism 300. At the same time, the housing fixing mechanism 200 also drives the housing 500 to move, and houses the housing 500 in the receiving cavity 310. Through the receiving cavity 310, the preliminary alignment of the battery cell 600 and the housing 500 can be conveniently achieved, the error during the insertion of the battery cell 600 into the housing can be reduced, and the scraping of the battery cell film by the entrance of the housing 500 can be avoided, thus damaging the battery cell film.

[0118] In some embodiments, in order to avoid the scraping of the battery cell film by the opening of the housing, an insertion diaphragm 3101 is disposed at a position corresponding to the edge of the receiving cavity 310 on the mold splitting mechanism. The insertion diaphragm 3101 extends towards the middle of the receiving cavity 310 for isolating the housing 500 from the battery cell 600.

[0119] Continue to refer to Figure 3 and Figure 4 , in order to avoid the scraping of the battery cell film by the opening of the housing, an insertion diaphragm 3101 is disposed at a position corresponding to the edge of the receiving cavity 310 in the embodiment of the present application. The insertion diaphragm 3101 can be disposed around the edge of the receiving cavity 310, or can be only disposed at a position corresponding to the long side of the receiving cavity 310, and is fixed to the mold splitting mechanism by means of adhesion or welding, etc., which is not limited herein. As Figure 4As shown, the shell - entering diaphragm 3101 is respectively arranged at the edges of the recessed structures of the first split - mold connecting plate 3402 and the second split - mold connecting plate 3412. When the first split - mold connecting plate 3402 and the second split - mold connecting plate 3412 enclose each other, the shell - entering diaphragm 3101 is located inside the accommodating cavity 310. When the shell 500 or the battery cell 600 moves into the accommodating cavity 310, the shell - entering diaphragm 3101 separates the shell 500 and the battery cell 600. The shell - entering diaphragm 3101 can be made of organic polymer materials. For example, polyimide is used. This kind of material has high insulation and high toughness, can well isolate the shell 500 and the battery cell 600, and protect the battery cell 600 from being scratched by the shell 500. At the same time, after the battery cell enters the shell, due to the good toughness of the shell - entering diaphragm, it can be conveniently withdrawn from between the shell 500 and the battery cell 600, without affecting the contact effect between the battery cell 600 and the shell 500, and can be reused.

[0120] By arranging the shell - entering diaphragm 3101, the shell 500 and the battery cell 600 first come into contact with the shell - entering diaphragm 3101. The shell - entering diaphragm 3101 forms a protective film on the surface of the battery cell to avoid scratching the battery cell 600 at the shell opening. When the battery cell enters the shell to a certain extent, the first split - mold mechanism and the second split - mold mechanism move to both sides respectively, driving the shell - entering diaphragm 3101 to be withdrawn from between the battery cell 600 and the shell 500.

[0121] In some embodiments, in order to better enable the battery cell 600 to enter the accommodating cavity 310, the embodiment of the present application is provided with guiding slopes at positions corresponding to the edge of the accommodating cavity 310 on the split - mold mechanism; the guiding slopes are used to guide the battery cell 600 to be accommodated in the accommodating cavity 310.

[0122] As Figure 4 shown, at the edges of the recesses of the first split - mold connecting plate 3402 and the second split - mold connecting plate 3412, a first guiding slope 3102 and a second guiding slope 3103 are respectively arranged. The guiding slopes are inclined towards the accommodating cavity 310 respectively, and are used to guide the shell 500 or the battery cell 600 to enter the accommodating cavity 310. When the battery cell 600 abuts against the guiding slope, an obliquely upward pressure is generated between the guiding slope and the battery cell 600. Under the action of this pressure, the shell - entering mechanism 300 will drive the split - mold connecting plate to move, thereby adaptively adjusting the position of the split - mold connecting plate according to the pressure, and then adjusting the position of the accommodating cavity 310, so that the battery cell 600 can be conveniently accommodated in the accommodating cavity 310, realizing alignment with the shell 500, thus avoiding scratching of the film on the battery cell at the shell opening when the battery cell 600 and the shell 500 cannot be aligned.

[0123] The guiding slope can be arranged on one side of the recesses of the first die - splitting connecting plate 3402 and the second die - splitting connecting plate 3412, or on both sides of the first die - splitting connecting plate 3402 and the second die - splitting connecting plate 3412 respectively. For example, the guiding slope can be arranged on the side of the recesses of the first die - splitting connecting plate 3402 and the second die - splitting connecting plate 3412 facing the battery cell fixing mechanism 400 to correct the trajectory of the battery cell 600 entering the accommodation cavity 310; or it can be arranged on the side of the recesses of the first die - splitting connecting plate 3402 and the second die - splitting connecting plate 3412 facing the housing fixing mechanism 200 to correct the trajectory of the housing 500 entering the accommodation cavity 310.

[0124] In some embodiments, a flaring mechanism is arranged at a position on the shell - inserting mechanism 300 corresponding to the housing fixing mechanism 200. When the housing fixing mechanism 200 drives the housing 500 to move so that the opening of the housing is located at the flaring mechanism, the flaring mechanism connects the outer wall of the opening of the housing and pulls the outer wall of the opening of the housing outward by moving to both sides, expanding the opening of the housing, so that the battery cell 600 can be easily placed into the housing 500.

[0125] The flaring mechanism can be arranged on one side or both sides of the position corresponding to the housing 500. The flaring mechanism can connect one side outer wall of the opening of the housing, or connect both side outer walls of the opening of the housing. Of course, it can also connect the outer walls around the opening of the housing. In order to achieve a better flaring effect, the flaring mechanism can adsorb the two long - side side walls of the opening of the housing, so as to achieve a better flaring effect.

[0126] The contact mode between the flaring mechanism and the outer wall can be by adsorption. For example, after contacting the outer wall through a suction cup, the flaring is carried out by evacuating the air, or the outer wall of the opening of the housing can be connected by bonding for flaring. Of course, other methods can also be used, which will not be elaborated here.

[0127] In the embodiment of the present application, by flaring the opening of the housing at the shell - inserting mechanism 300, the opening of the housing 500 is enlarged, so that the battery cell 600 can conveniently enter the housing 500, avoiding damage to the battery cell film caused by the edge of the opening of the housing.

[0128] In some embodiments, in order to better flare the housing 500, a flaring mechanism is arranged on the side of the shell - inserting mechanism body 301 facing the housing fixing mechanism 200. The flaring mechanism is arranged corresponding to the accommodation cavity 310 and is used for flaring the housing 500 accommodated in the accommodation cavity 310.

[0129] In some embodiments, such as Figure 3As shown in the figure, a first flaring mechanism 320 and a second flaring mechanism 321 are respectively arranged on the main body 301 of the shelling mechanism facing one side of the shell fixing mechanism 200. The first flaring mechanism 320 and the second flaring mechanism 321 are respectively located on both sides of the accommodating cavity 310. When the shell 500 is accommodated in the accommodating cavity 310, the first flaring mechanism 320 and the second flaring mechanism 321 are respectively connected to the outer walls on both sides of the shell 500, and drive the shells 500 on both sides to expand outwards, expanding the entrance of the shell 500, so that the battery cell 600 can be conveniently accommodated. In order to improve the flaring effect, the first flaring mechanism 320 and the second flaring mechanism 321 are arranged on both sides in the thickness direction of the shell, and the relatively wide side walls on both sides are flared, which can improve the flaring effect. Of course, flaring mechanisms can also be arranged at both ends of the accommodating cavity 310 to flare the side walls on both sides in the width direction of the shell 500. It is also possible to flare the four side walls of the shell 500 at the same time to achieve the best flaring effect. By setting the flaring mechanism, a better flaring effect can be achieved, enabling the battery cell 600 to enter the shell 500 more conveniently.

[0130] In some embodiments, the flaring mechanism includes a flaring suction cup 3211; the flaring suction cup 3211 is used for adsorbing the side wall at the opening of the shell.

[0131] Figure 6 The partial enlarged view of the flaring mechanism is shown. The flaring mechanism includes a flaring cylinder 3210 and a flaring suction cup 3211. The flaring cylinder 3210 drives the flaring suction cup 3211 to move reciprocally. The flaring suction cup 3211 is used for adsorbing the outer wall of the shell 500. When the flaring suction cup 3211 abuts against the outer wall of the shell 500, the suction cup discharges the internal air and adsorbs the outside of the shell on the suction cup by relying on the pressure of the external gas. The flaring cylinder 3210 drives the suction cup to move outwards, thereby realizing the flaring treatment of the shell.

[0132] By setting the flaring suction cup 3211, the outer wall can be conveniently adsorbed and connected and released. The structure is simple and can be repeatedly operated for a long time.

[0133] The battery cell shelling device 1000 provided by the embodiment of the present application, by setting an XY floating slider on the shelling mechanism 300, enables the shelling mechanism 300 to freely float relative to the main power mechanism 100 and the battery cell fixing mechanism 400, and can flexibly and automatically adjust the positions of the shell 500 and the battery cell 600, greatly improving the alignment efficiency of the battery cell 600 and the shell 500. By further setting a reset mechanism 350, after the assembly of the battery cell 600 and the shell 500 is completed, the shelling mechanism 300 is quickly reset through the reset mechanism 350, avoiding excessive position deviation between the shell 500 and the battery cell 600 after multiple assemblies, and greatly improving the assembly efficiency of the battery cell 600 and the shell 500.

[0134] In addition, by arranging the housing fixing mechanism 200, the housing inserting mechanism 300, and the battery cell fixing mechanism 400 in a vertical structure, the problem of damage to the battery cell film caused by the gravity of the housing during horizontal insertion of the battery cell into the housing is avoided. Further, by providing a receiving cavity 310 on the housing inserting mechanism 300, the housing 500 and the battery cell 600 can be vertically aligned through the receiving cavity 310, thus avoiding damage to the battery cell 600 caused by misalignment between the battery cell 600 and the housing 500. To avoid rubbing between the battery cell 600 and the housing 500, an insertion diaphragm 3101 is provided on the mold splitting mechanism to isolate the battery cell 600 and the housing 500 during assembly, thereby avoiding damage to the battery cell 600 caused by the opening of the housing. At the same time, in order to conveniently adjust the position of the housing 500 to realign it when there is an error in the alignment position between the battery cell 600 and the housing 500, a guiding ramp is provided on the mold splitting mechanism to adjust the positions of the battery cell 600 and the housing 500. By providing a flaring mechanism on the housing inserting mechanism 300, flaring treatment of the housing is achieved, enabling the battery cell 600 to be conveniently placed into the housing 500.

[0135] An embodiment of the present application further provides a battery cell assembly device, including any one of the battery cell housing inserting devices 1000 proposed in the above embodiments. The battery cell assembly device may include a battery cell preparation device, a housing preparation device, and the battery cell housing inserting device 1000. The battery cell preparation device is used to convey the battery cell 600 to the battery cell housing inserting device 1000. A flow line operation mode can be adopted. After one battery cell 600 is inserted into the housing, another battery cell 600 can be quickly conveyed to a suitable position for the battery cell fixing mechanism 400 to fix the battery cell. The housing preparation device is used to provide the housing 500 for the battery cell housing inserting device 1000. By conveying the housing 500 to the battery cell housing inserting device 1000, the battery cell housing inserting device completes the assembly of the battery cell 600 and the housing 500. The battery cell housing inserting device 1000 is used to complete the assembly of the housing 500 and the battery cell 600, and its working mode is the same as that provided in the above embodiments and will not be elaborated here.

[0136] An embodiment of the present application further provides a battery cell assembly method. This method can be applied to the battery cell housing inserting device proposed in the above embodiments or other battery cell production devices for assembling the battery cell and the housing.

[0137] As Figure 8 shown, the execution flow chart of the battery cell assembly method proposed in an embodiment of the present application includes:

[0138] Step 701: Provide a housing and a battery cell.

[0139] This step is in the material preparation stage, providing the housing and the battery cell to be assembled for the assembly of the battery cell. The providing method can be various. For example, the feeding method in an automated production line can be adopted. That is, the battery cell is automatically prepared by a battery cell material preparation device. After one battery cell is assembled, the next battery cell is automatically provided. The housing is automatically prepared by a housing material preparation device. After one housing is assembled, the next housing is automatically provided. Of course, other material preparation methods can also be adopted.

[0140] Step 702: Move the housing and the battery cell to the accommodation cavity respectively, and adjust the relative positions of the battery cell and the housing.

[0141] Move the housing and the battery cell to the accommodation cavity respectively. The accommodation cavity provides the function of preliminary positioning for the battery cell and the housing. Through the accommodation cavity, the positioning of the battery cell and the housing can be conveniently realized, and the damage to the battery cell caused by inaccurate positioning of the housing and the battery cell can be reduced. After the housing and the battery cell are located in the accommodation cavity, adjust the relative positions of the two to facilitate the subsequent assembly of the battery cell into the housing.

[0142] Step 703: Sheath the housing outside the battery cell.

[0143] Move the housing or the battery cell to sheath the housing outside the battery cell.

[0144] Through the battery cell assembly method provided by the embodiments of the present application, the relative positions of the battery cell and the housing can be adjusted, so that the battery cell and the housing can be adaptively aligned, facilitating the battery cell to enter the housing and avoiding the damage to the battery cell or the housing caused by the position error between the battery cell and the housing.

[0145] In some embodiments, in the step of providing the housing and the battery cell, the housing and the battery cell are arranged vertically.

[0146] By arranging the housing and the battery cell vertically, the battery cell and the housing can be assembled into the housing in an upright manner, that is, in a vertical housing insertion manner, thus avoiding the problems that the battery cell is difficult to be pushed into the housing due to downward deviation during the movement of the battery cell caused by gravity in the traditional horizontal housing insertion manner and the problem of damage to the battery cell film.

[0147] In some embodiments, in the step of arranging the housing and the battery cell vertically, the battery cell is located below the housing. In this way, during the housing insertion assembly process of the battery cell and the housing, they are always in an upright state, and vertical housing insertion assembly can be carried out, avoiding the problems that the battery cell is difficult to be pushed into the housing due to downward deviation during the movement of the battery cell caused by gravity in the traditional horizontal housing insertion manner and the problem of damage to the battery cell film.

[0148] In some embodiments, in order to improve the efficiency of cell assembly, the accommodating cavity is reset in time after the assembly is completed. Through the reset operation, the device can be reset after each cell is put into the shell, avoiding the expansion of the position deviation between the shell and the cell, and improving the assembly efficiency of the cell and the shell.

[0149] In some embodiments, in order to facilitate the correction of the position of the battery cell and the shell, a guide slope is set at the edge of the accommodating cavity. When moving the shell and the battery cell, the shell is moved into the accommodating cavity, and the battery cell is also moved to the accommodating cavity. The position of the accommodating cavity is corrected by the guide slope, and the battery cell is accommodated in the accommodating cavity.

[0150] By setting a guide slope, a certain pressure can be generated on the accommodating cavity when the battery cell abuts against the guide slope. Under the action of pressure, the accommodating cavity actively adjusts its relative position with the battery cell, so that the position of the shell and the battery cell are automatically aligned, thereby avoiding the scratching of the battery cell by the shell and damage to the battery cell coating due to position deviation between the battery cell and the shell.

[0151] In some embodiments, in order to prevent the shell from damaging the battery cell, a shell diaphragm is provided at the edge of the accommodating cavity, and the shell abuts against the battery cell through the shell diaphragm, and the shell is sleeved on the outside of the battery cell. When the shell moves to a preset position outside the battery cell, the shell diaphragm is moved to both sides of the battery cell and the shell diaphragm is pulled out of the shell. After the assembly is completed, as the accommodating cavity is reset, the shell film is also reset.

[0152] In order to further protect the coating on the outside of the battery cell, a shell diaphragm is set at the edge of the accommodating cavity when assembling the battery cell and the shell. The shell diaphragm is used to isolate the battery cell and the shell to avoid direct contact between the shell and the battery cell, thereby reducing the damage to the battery cell caused by the shell. At the entrance of the shell, a shell diaphragm is set between the battery cell and the shell. The shell diaphragm protects the battery cell. As the battery cell gradually enters the shell, the shell diaphragm needs to be pulled out in time to avoid the shell diaphragm from accidentally entering the battery cell and affecting the battery performance.

[0153] By providing a shell diaphragm, the shell and the battery cell are not in direct contact, thus avoiding damage to the battery cell coating caused by the shell, and protecting the battery cell to a great extent.

[0154] In some embodiments, between step 702 and step 703 , there is further included step 702 ′: expanding the shell.

[0155] When the shell and the battery cell are moved into the accommodating cavity, the shell opening is expanded by the expansion mechanism. The expansion mechanism is connected to the outer wall of the shell opening, and the outer wall of the shell opening is pulled outward by moving to both sides to expand the shell opening, so that the battery cell can be easily placed into the shell, and the edge of the shell opening is prevented from damaging the battery cell coating.

[0156] The contact mode between the flaring mechanism and the outer wall can be achieved by adsorption. For example, after contacting the outer wall through a suction cup, flaring is carried out by means of vacuum pumping. It can also be achieved by bonding to connect the outer wall at the opening of the housing for flaring. Of course, other methods can also be adopted, which will not be elaborated here.

[0157] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application.
