[0041] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0042] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] As shown in Figure 1 , Figure 2 and Figure 3 , the present application provides a device for putting battery cell modules into boxes, comprising:

[0044] A rack 100, a bearing member 200 movably arranged on the rack 100, the bearing member 200 being used for bearing a battery cell module 10 and a box 20, wherein the battery cell module 10 comprises a plurality of sub-battery cells 11 adhered to each other;

[0045] An integrating member 300, the integrating member 300 being used for clamping the battery cell module 10 to reshape the battery cell module 10;

[0046] A first turnover member 400, the first turnover member 400 being arranged on the rack 100, the first turnover member 400 being used for clamping and turning over the battery cell module 10;

[0047] A second turnover member 500, the second turnover member 500 being arranged on the rack, the second turnover member 500 being used for clamping and turning over the box 20, and making the box 20 cover the battery cell module 10 from top to bottom.

[0048] In operation, the battery cell module 10 can be reshaped by the integrating member 300 to improve the adhesion stability between the sub-battery cells 11 in the battery cell module 10. Secondly, the battery cell module 10 is turned over by 180 degrees by the first turnover member 400, the box 20 is turned over by 180 degrees by the second turnover member 500 and covers the battery cell module 10, so that the bottom surface of the battery cell module 10 is adhered to the inner bottom surface of the box 20, and the putting of the battery cell module 10 into the box 20 is completed. Therefore, in the process of the battery cell module 10 entering the box 20, the battery cell module 10 does not need to be moved, only the box 20 needs to be moved, thereby reducing the possibility of displacement between the sub-battery cells 11. Moreover, in the process of the box 20 being pressed down, the displacement of the sub-battery cells 11 in the height direction can be effectively limited by the bearing member 200, thereby improving the installation effect of the battery cell module 10 in the box 20, improving the quality of the battery, and solving the problem that the installation effect of the battery cell module 10 in the box 20 is poor, thereby affecting the quality of the battery.

[0049] It should be noted that the shape of the rack 100 is not limited. The carrier 200 can be a tray or a support seat, and the number of trays or support seats can be one, two or other numbers. The carrier 200 can be movably arranged on the rack 100 by a driving member such as a conveyor belt, a pneumatic cylinder, a hydraulic cylinder, a mechanical arm, etc., so as to control the movement or rotation of the carrier 200 by the driving member. In implementation, the sub battery cell 11, the battery cell module 10 or the box 20 can be placed on the carrier 200, and the carrier 200 is used for conveying.

[0050] The integrating member 300, the first turnover member 400 and the second turnover member 500 can all be mechanical arms, which can be existing products and the models are not limited.

[0051] For example, in the integrating member 300, the mechanical arm has a plurality of pneumatic cylinders and clamps, and the pneumatic cylinders control the movement of the clamps, so that the plurality of clamps can clamp the battery cell module 10 from multiple directions. For example, the battery cell module 10 can be clamped from all around by the integrating member 300, and the battery cell module 10 can be pressed down from the top at the same time, so as to reshape the battery cell module 10.

[0052] In the first turnover member 400, the mechanical arm also has a plurality of pneumatic cylinders and clamps, and the mechanical arm also has a rotating member which can be a rotating pneumatic cylinder or a motor. The pneumatic cylinders and the clamps are connected to the mechanical arm through the rotating member. Under the control of the pneumatic cylinders, each clamp can clamp the battery cell module 10 from six surfaces of the battery cell module 10, and then the battery cell module 10 and the clamps are turned over by the rotating member.

[0053] In the second turnover member 500, the mechanical arm also has a plurality of pneumatic cylinders and clamps, and the mechanical arm also has a rotating member which can be a rotating pneumatic cylinder or a motor. The pneumatic cylinders and the clamps are connected to the mechanical arm through the rotating member. Under the control of the pneumatic cylinders, each clamp can clamp the box 20, and then the box 20 is turned over by the rotating member. Subsequently, the box 20 is covered on the battery cell module 10 from top to bottom by the mechanical arm, and a downward pressure is applied to the box 20.

[0054] In work, at least one side surface of the sub battery cell 11 is coated with glue, and then a plurality of sub battery cells 11 are arranged to form a battery cell module 10. Part of the sub battery cells 11 are arranged along the length direction, and part of the sub battery cells 11 are arranged along the width direction. Then, the battery cell module 10 is placed on the carrier 200, and the battery cell module 10 is clamped from all around and the top by the integrating member 300, so as to reshape the battery cell module 10.

[0055] Subsequently, the first flip member 400 is used to clamp and flip the cell module 10 so that the bottom surface of the cell module 10 faces upward, and then thermally conductive structural adhesive is applied to the bottom surface of the cell module 10. The second flip member 500 is then used to clamp and flip the box 20 so that the box 20 covers the cell module 10 from top to bottom, and downward pressure is applied to the box 20, thereby bonding the bottom surface of the cell module 10 to the inner bottom surface of the box 20, completing the placement of the cell module 10 into the box.

[0056] Therefore, when the battery module 10 enters the box body 20, there is no need to move the battery module 10, only the box body 20 needs to be moved, thereby reducing the possibility of displacement between the sub-battery cells 11; and, when the box body 20 is pressed down, the support member 200 can also effectively limit the displacement of the sub-battery cells 11 in the height direction, thereby improving the installation effect of the battery module 10 in the box body 20 and improving the battery quality.

[0057] Finally, the first flip member 400 or the second flip member 500 can be used to clamp the box body 20 and the battery cell module 10 as a whole, and the box body 20 and the battery cell module 10 can be flipped over so that the bottom surface of the battery cell module 10 faces downward to enter the subsequent processing steps.

[0058] For example, Figure 1 As shown, the carrier 200 may include two trays, namely tray 1 210 and tray 2 220. Tray 1 210 and tray 2 220 can be moved on the rack 100 via a conveyor belt and can also be picked up by a robotic arm and brought into contact with the cell module 10. During operation, tray 1 210 drives the cell module 10 to the first flip member 400, and then tray 2 220 is brought into contact with the upper surface of the cell module 10. The first flip member 400 then clamps the cell module 10, tray 1 210, and tray 2 220 as a whole and flips them 180 degrees, so that the cell module 10 falls on tray 2 20. Then, tray 2 220 carries the cell module 10 away from the first flip member 400. Then, thermal conductive structural adhesive is applied to the bottom surface of the cell module 10, and then the cell module 10 is carried to the second flip member 500 via tray 1 210. The second flip member 500 clamps and flips the box 20, and then the box 20 is lowered and turned upside down on the cell module 10, while applying downward pressure to the box 20. After the thermal conductive structural adhesive is cured, tray 2 220 is used to continue carrying the cell module 10 and the box 20 as a whole back to the first flip member 400, and then tray 1 210 is re-attached to the current upper surface of the cell module 10 and the box 20 as a whole. Then, the first flip member 400 drives tray 1 210, tray 2 220, the cell module 10 and the box 20 as a whole to flip 180 degrees a second time. Then, tray 2 220 is separated from the cell module 10, and tray 1 210 and the cell module 10 and the box 20 as a whole leave the first flip member 400.

[0059] In actual implementation, a gluing mechanism, such as a glue nozzle or a glue brush, can be additionally arranged on the rack 100, so that the side surface of the sub battery cell 11 can be glued by the gluing mechanism, or the bottom surface of the battery cell module 10 can be coated with a heat-conducting structural glue.

[0060] In summary, the battery cell module boxing device provided by the application can shape the battery cell module 10 by the integrating piece 300, so as to improve the bonding stability between the sub battery cells 11 in the battery cell module 10. Then, the battery cell module 10 is turned over by 180 degrees by the first turning piece 400, the box 20 is turned over by 180 degrees by the second turning piece 500 and covers the battery cell module 10, so that the bottom surface of the battery cell module 10 is bonded to the inner bottom surface of the box 20, and the battery cell module 10 is completed to be boxed. Thus, in the process of the battery cell module 10 entering the box 20, the battery cell module 10 does not need to be moved, and only the box 20 needs to be moved, so as to reduce the possibility of displacement between the sub battery cells 11. In the process of the box 20 being pressed down, the displacement of the sub battery cells 11 in the height direction is effectively limited by the bearing piece 200, so as to improve the installation effect of the battery cell module 10 in the box 20, improve the quality of the battery, and solve the problem that the installation effect of the battery cell module 10 in the box 20 is poor, which affects the quality of the battery.

[0061] The battery cell module boxing method provided by the application adopts the battery cell module boxing device in any one of the above embodiments, and includes the following steps.

[0062] The battery cell module 10 is clamped by the integrating piece 300 in the battery cell module boxing device, so as to shape the battery cell module 10. The battery cell module 10 includes a plurality of sub battery cells 11 bonded to each other, part of the sub battery cells 11 are arranged along the width direction of the sub battery cells 11, and part of the sub battery cells 11 are arranged along the length direction of the sub battery cells 11.

[0063] The battery cell module 10 is placed on the bearing piece 200 in the battery cell module boxing device, the battery cell module 10 is clamped and turned over by the first turning piece 400 in the battery cell module boxing device, so that the bottom surface of the battery cell module 10 faces upward, and the bottom surface of the battery cell module 10 is glued.

[0064] The box 20 is clamped and turned over by the second turning piece 500 in the battery cell module boxing device, so that the opening of the box 20 faces downward, and the box 20 covers the battery cell module 10 from top to bottom, so that the bottom surface of the battery cell module 10 is bonded to the inner bottom surface of the box 20, and the battery cell module 10 is installed in the interior of the box 20.

[0065] Finally, the whole of the box 20 and the battery cell module 10 can be clamped by the first or second turnover member 400, 500 and turned over so that the bottom surface of the battery cell module 10 faces downward for subsequent processing. In this embodiment, the whole of the box 20 and the battery cell module 10 is clamped by the first turnover member 400 and turned over.

[0066] Thus, the battery cell module 10 can be shaped by the integrating member 300 to improve the bonding stability between the battery cells 11 in the battery cell module 10. In addition, during the process of covering the battery cell module 10 from top to bottom by the box 20, the battery cell module 10 does not need to be moved, only the box 20 needs to be moved, thereby reducing the possibility of displacement between the battery cells 11. Furthermore, during the process of pressing down the box 20, the displacement of the battery cells 11 in the height direction can be effectively limited by the bearing member 200, thereby improving the installation effect of the battery cell module 10 in the box 20 and improving the quality of the battery.

[0067] In some embodiments, before the battery cell module 10 is clamped by the integrating member 300 in the device for putting the battery cell module into the box, the following steps are further included:

[0068] The battery cells 11 are glued on at least one side in the width direction, and then a plurality of the battery cells 11 arranged in the length direction are sequentially bonded to form a single-row battery cell group.

[0069] A plurality of single-row battery cell groups are made, and then a plurality of the single-row battery cell groups arranged in the width direction are sequentially bonded to form the battery cell module 10.

[0070] Thus, the plurality of battery cells 11 can be made into the battery cell module 10 as a whole, and the battery cells 11 are bonded to each other to ensure the stability of the battery cell module 10 as a whole.

[0071] Specifically, when the plurality of battery cells 11 arranged in the length direction are clamped by the integrating member 300, the battery cells 11 can be turned over so that the length direction of the battery cells 11 extends vertically, and then the plurality of battery cells 11 are arranged vertically and clamped by the integrating member 300 to form a single-row battery cell group. Alternatively, the length direction of the battery cells 11 can extend horizontally, and then the plurality of battery cells 11 are arranged in the horizontal direction.

[0072] For example, six battery cells 11 can form a single-row battery cell group, and twenty-two single-row battery cell groups can form the battery cell module 10. Of course, the number of the battery cells 11 and the single-row battery cell groups can be other numbers, which are not limited.

[0073] Glue is applied to at least one side of the sub battery cell 11 in the width direction of the sub battery cell 11, and the coverage of the glue on the side of the sub battery cell 11 is greater than or equal to 95%.

[0074] Thus, the bonding effect between the two adjacent sub battery cells 11 is further ensured. For example, the coverage of the glue on the side of the sub battery cell 11 can be 95%, 96%, 97%, 98% or other values. The type of glue is not limited.

[0075] In some embodiments, a plurality of single-row battery cell groups arranged in sequence in the width direction of the sub battery cell 11 are sequentially bonded, comprising:

[0076] A buffer pad layer is arranged on at least one side of the sub battery cell 11 in the length direction of the sub battery cell 11, and a plurality of single-row battery cell groups arranged in sequence in the width direction of the sub battery cell 11 are sequentially bonded, so that the buffer pad layer is clamped between the two adjacent single-row battery cell groups.

[0077] Specifically, as shown in Figure 4 The sub battery cell 11 is a cuboid structure, and the pole 14 faces upward, so that the side of the sub battery cell 11 has two opposite small cell surfaces 12 and two opposite large cell surfaces 13. It should be noted that among the two adjacent sides of the sub battery cell 11, the side with a relatively small area is the small cell surface 12, and the side with a relatively large area is the large cell surface 13. At this time, glue is applied to at least one side of the sub battery cell 11 in the width direction of the sub battery cell 11, that is, glue is applied to at least one small cell surface 12 of the sub battery cell 11; and a buffer pad layer is arranged on at least one side of the sub battery cell 11 in the length direction of the sub battery cell 11, that is, a buffer pad layer is arranged on at least one large cell surface 13 of the sub battery cell 11.

[0078] In the present embodiment, among the plurality of sub battery cells 11 distributed in the width direction of the sub battery cell 11, only one buffer pad layer is required between the two adjacent sub battery cells 11, and at this time, the buffer pad layer can be bonded to any one of the two adjacent sub battery cells 11. In implementation, the side of the buffer pad layer away from the sub battery cell 11 can also be glued, thereby ensuring the stability of the bonding between the two adjacent single-row battery cell groups. The buffer pad layer can be silicone, rubber, foam, aerogel or other buffer materials, so as to absorb the thermal expansion of the sub battery cell 11 during work through the buffer pad layer.

[0079] In some embodiments, glue can be applied only between the two adjacent small cell surfaces 12, a buffer pad layer and glue can be arranged between the two adjacent large cell surfaces 13, and the outer surface of the battery cell module 10 as a whole is not glued or provided with a buffer pad layer.

[0080] In some embodiments, the battery cell module 10 is clamped by an integrated piece 300 in a device into which the battery cell module is placed, comprising:

[0081] The cell module 10 is clamped from all sides by the integration piece 300, and at the same time, the cell module 10 is pressed from the top by the integration piece 300.

[0082] In this way, the cell module 10 is integrated, the stability of the adhesion between the sub-cells 11 is improved, and the stability of the whole cell module 10 is improved.

[0083] Specifically, the cell module 10 is clamped from all sides by the integration piece 300, wherein the pressure of the integration piece 300 on the cell module 10 is 3000-5000N.

[0084] The cell module 10 is pressed from the top by the integration piece 300, wherein the pressure of the integration piece 300 on the cell module 10 is 2500-3000N.

[0085] The pressure maintaining time is 30-60min.

[0086] In this way, the cell module 10 is shaped by the integration piece 300, and the pressure and pressure maintaining time are reasonably applied to the cell module 10 to ensure that the sub-cells 11 have better adhesion effect between them, and at the same time, the possibility of damage to the sub-cells 11 due to excessive stress is reduced.

[0087] For example, the pressure of the integration piece 300 on the cell module 10 from all sides can be 3000N, 3500N, 4000N, 4500N, 5000N or other values. The pressure of the integration piece 300 on the cell module 10 from the top can be 2500N, 2700N, 2800N, 2900N, 3000N or other values. The pressure maintaining time can be 30min, 40min, 45min, 50min, 60min or other values.

[0088] In some embodiments, the cell module 10 is clamped and flipped by a first flipping piece 400 in the device into which the cell module 10 is put, so that the bottom surface of the cell module 10 faces upward, comprising:

[0089] The cell module 10 is pressed from all six sides by the first flipping piece 400, and then the cell module 10 is flipped so that the bottom surface of the cell module 10 faces upward.

[0090] In this way, the stability of the cell module 10 during the flipping process can be ensured, and the possibility of displacement of the sub-cells 11 in the cell module 10 can be reduced.

[0091] In some embodiments, the bottom surface of the battery cell module 10 is coated with glue, including: coating the bottom surface with a heat-conducting structural glue, wherein the coverage of the heat-conducting structural glue on the bottom surface is ≥ 90%. Thus, when the inner bottom surface of the box 20 is bonded to the bottom surface of the battery cell module 10, the bonding effect between the two can be ensured. For example, the coverage of the heat-conducting structural glue on the bottom surface can be 90%, 92%, 93%, 95%, 98%, or other values.

[0092] The heat-conducting structural glue can be an epoxy resin-based heat-conducting glue, a silicone-based heat-conducting glue, a polyurethane-based heat-conducting glue, an acrylic acid-based heat-conducting glue, or other heat-conducting glues.

[0093] In some embodiments, the box 20 is covered from top to bottom with the battery cell module 10, so that the bottom surface of the battery cell module 10 is bonded to the inner bottom surface of the box 20, including:

[0094] The box 20 is covered from top to bottom with the battery cell module 10, and the second turnover piece 500 is used to apply a downward pressure to the box 20 so that the bottom surface of the battery cell module 10 is bonded to the inner bottom surface of the box 20, wherein the downward pressure applied by the second turnover piece 500 to the box 20 is 2500-3000N, and the holding pressure time is 25-50min.

[0095] Thus, by reasonably applying pressure and holding pressure time to the box 20, a better bonding effect between the box 20 and the battery cell module 10 can be ensured while reducing the possibility of damage to the sub-battery cell 11 or the overall battery cell module 10 due to excessive stress.

[0096] For example, the downward pressure applied by the second turnover piece 500 to the box 20 can be 2500N, 2700N, 2800N, 2900N, 3000N, or other values. The holding pressure time can be 25min, 30min, 35min, 40min, 50min, or other values.

[0097] Thus, as shown in Figure 5 the main process of the battery cell module into the box is as follows: the battery cell small surface 12 of the sub-battery cell 11 is coated with glue, and the battery cell large surface is pasted with a buffer pad layer; the battery cell small surfaces 12 of a plurality of sub-battery cells 11 are arranged into a single-row battery cell group; a plurality of single-row battery cell groups are arranged into a battery cell module 10; the battery cell module 10 is shaped by the integration piece 300; the bottom surface of the battery cell module 10 is coated with glue after being turned over by 180 degrees; the box 20 is inverted and buckled on the battery cell module 10 after being turned over by 180 degrees; the glue is pressed and cured; the box 20 and the battery cell module 10 are turned over by 180 degrees as a whole, and the process of putting into the box is completed.

[0098] In addition, the carrier 200 can include two trays, namely a first tray 210 and a second tray 220 in the implementation. In operation, the first tray 210 drives the battery cell module 10 to the first turnover device 400, then the second tray 220 contacts the upper surface of the battery cell module 10, and the first turnover device 400 clamps and turns over 180 degrees from the six surfaces of the battery cell module 10, the overall clamping of the battery cell module 10, the first tray 210 and the second tray 220, so that the battery cell module 10 falls on the second tray 220, and then the second tray 220 drives the battery cell module 10 away from the first turnover device 400. Then, the bottom surface of the battery cell module 10 is smeared with a heat-conducting structural adhesive, and the first tray 210 drives the battery cell module 10 to the second turnover device 500, the second turnover device 500 clamps and turns over the box 20, and then the box 20 is lowered and inverted on the battery cell module 10, while the second turnover device 500 applies a downward pressure to the box 20 and keeps the pressure. After the heat-conducting structural adhesive is cured, the second tray 220 continues to drive the overall battery cell module 10 and the box 20 back to the first turnover device 400, and then the first tray 210 is reattached to the upper surface of the overall battery cell module 10 and the box 20, and then the first turnover device 400 drives the overall first tray 210, second tray 220, battery cell module 10 and box 20 to turn over 180 degrees again, and then the second tray 220 is separated from the battery cell module 10, and the first tray 210 drives the overall battery cell module 10 and the box 20 away from the first turnover device 400, so as to enter the subsequent process.

[0099] In summary, the method for putting the battery cell module into the box provided by the application can reshape the battery cell module 10 by the integrating device 300 to improve the bonding stability between the sub-battery cells 11 in the battery cell module 10, and in the process of putting the battery cell module 10 into the box 20, the battery cell module 10 does not need to be moved, only the box 20 needs to be moved, thereby reducing the possibility of displacement between the sub-battery cells 11, and in the process of pressing the box 20, the carrier 200 can effectively limit the displacement of the sub-battery cells 11 in the height direction, thereby improving the installation effect of the battery cell module 10 in the box 20 and improving the quality of the battery, and solving the problem of poor installation effect of the battery cell module 10 in the box 20, which affects the quality of the battery.
