Description

Technical Field

[0001] The utility model relates to the technical field of rubber pressing equipment, and in particular, to a box body support assembly of a rubber pressing device, a rubber pressing device and a battery production system. Background Art

[0002] In the related art, the battery cell of a battery needs to be fixed to a box body by bonding with structural adhesive to meet the strength requirement. However, during the manufacturing process, the box body will have irreversible plastic deformation under pressure, resulting in unqualified overall dimensions of the battery, increased consumption of structural adhesive, increased cost, and easy peeling of the structural adhesive from the battery cell, affecting the structural strength. Summary of the Utility Model

[0003] An embodiment of the utility model provides a box body support assembly of a rubber pressing device, a rubber pressing device and a battery production system, which can prevent the box body from undergoing plastic deformation, reduce the consumption of structural adhesive, and improve the structural strength.

[0004] In a first aspect, an embodiment of the utility model provides a box body support assembly of a rubber pressing device for the rubber pressing process of a battery cell and a box body. The box body support assembly includes: a seat body; a first support member, which is installed on the seat body and is used for supporting the bottom plate of the box body; and a second support member, which is installed on the seat body and is located outside the first support member and is used for supporting the side beam of the box body.

[0005] In the above technical solution, the bottom plate of the box body is supported by the first support member, and the side beam of the box body is supported by the second support member, so that during the rubber pressing process, the box body is not easily deformed plastically, which is beneficial to improving the overall dimensional accuracy of the battery, reducing the consumption of structural adhesive, improving the bonding reliability between the battery cell and the box body, reducing the probability of peeling between the battery cell and the structural adhesive, and improving the structural strength.

[0006] In some embodiments, there are multiple first support members, wherein at least one first support member is a hard support member, and at least one first support member is a soft support member. The hard support member is used for supporting the plate body of the bottom plate, and the soft support member is used for supporting the reinforcing beam of the bottom plate, and at least part of the soft support member can be elastically deformed.

[0007] In the above technical solution, the hard support member supports the plate body, which can provide more stable support for the plate body, reduce the deformation amount of the plate body during the glue pressing process, and thus effectively improve the plastic deformation problem of the plate body. The soft support member supports the reinforcing beam, so that after the soft support member undergoes elastic deformation, it can provide sufficient support for the reinforcing beam to reduce the deformation amount of the reinforcing beam and reduce the risk of plastic deformation; the elastic deformation process of the soft support member can avoid hard contact with the reinforcing beam to absorb tolerances, thereby reducing the risk of plastic deformation caused by the compression of the inner cavity of the reinforcing beam. The plastic deformation amounts of the plate body and the reinforcing beam obtained after glue pressing are effectively reduced, and the overall dimensional accuracy of the battery is higher.

[0008] In some embodiments, the soft support member includes a frame portion and a support portion. The frame portion is installed on the seat body, and the support portion is installed on the frame portion. The support portion of the soft support member is used to support the reinforcing beam and is elastically deformable, and the hardness of the frame portion of the soft support member is greater than the hardness of the support portion.

[0009] In the above technical solution, the support portion of the soft support member has a smaller hardness, enabling the support portion to undergo elastic deformation and effectively reducing the risk of plastic deformation of the reinforcing beam; the frame portion of the soft support member has a greater hardness, enabling the frame portion to provide reliable support for the support portion, and further enabling the overall soft support member to provide reliable support for the reinforcing beam.

[0010] In some embodiments, in the non-deformed state of the soft support member, in the direction away from the seat body, the support surface of the soft support member for supporting the reinforcing beam is higher than the support surface of the hard support member for supporting the plate body.

[0011] In the above technical solution, during the glue pressing process, the support surface of the soft support member first contacts the reinforcing beam, and the soft support member is compressed and undergoes elastic deformation, and then the support surface of the hard support member contacts the plate body. The reinforcing beam first contacts the box body support assembly, enabling the stronger reinforcing beam to share most of the pressure in advance, which is beneficial to reducing the pressure on the plate body with lower strength and reducing the plastic deformation amount of the plate body.

[0012] In some embodiments, the support surface of the hard support member near the middle of the plate body is the first support surface, and the support surface of the hard support member near the edge of the plate body is the second support surface. In the direction away from the seat body, the second support surface is higher than the first support surface.

[0013] In the above technical solution, the distance between the second support surface and the edge of the plate body is approximately equal to the distance between the first support surface and the middle of the plate body, and different regions of the plate body are more evenly stressed, so the stress is more uniform, which is beneficial to improving the glue pressing uniformity of the structural adhesive.

[0014] In some embodiments, an avoidance area is provided on the supporting surface of the first support member, and the avoidance area is recessed or penetrates through the first support member in a direction close to the base body; and / or, the first support member includes a plurality of support bodies, and the plurality of support bodies are arranged at intervals along the length direction of the reinforcing beam of the bottom plate.

[0015] In the above technical solution, the avoidance area and the gap between two adjacent support bodies can avoid the special-shaped structure on the bottom plate, so that when the first support member meets the support requirement for the bottom plate, the influence of the special-shaped structure on the bottom plate can be reduced. The structure of the first support member is simpler, and it is easier to achieve surface-to-surface contact between the first support member and the bottom plate, improve the support stability, and reduce the production cost of the first support member.

[0016] In some embodiments, the second support member is provided with a positioning pin, and the positioning pin is used for plugging and positioning with the side beam.

[0017] In the above technical solution, through the plugging of the positioning pin and the side beam, positioning in a direction perpendicular to the glue pressing direction can be achieved, such as positioning in a direction perpendicular to the up-and-down direction, so that the relative positions of the battery cell and the box body are stable, and the relative positions of the box body and the box body support assembly are stable. Thereby, the assembly accuracy and bonding reliability of the battery cell and the box body after glue pressing are improved, and the support stability of the first support member for the box body is improved, and the effect of reducing the plastic deformation of the box body is better.

[0018] In some embodiments, the first support member and / or the second support member includes a frame body part and a support part, the support part is detachably connected to the frame body part, there are a plurality of support parts, and the plurality of support parts are alternatively installed on the frame body part, and at least one of the shapes, structures, and support areas of the plurality of support parts is different.

[0019] In the above technical solution, through the detachable connection between the support part and the frame body part, and at least one of the shapes, structures, and support areas of the plurality of support parts is different, so that in the application process, the corresponding support part can be replaced and installed on the frame body part according to the differences in the bottom plate or side beam to be supported, so that the box body support assembly can meet the support requirements of different box bodies, and the same base body and frame body part can be used for different box bodies, and only the support part needs to be replaced, which is beneficial to improving the versatility of the box body support assembly and reducing the production cost.

[0020] In some embodiments, the box support assembly further includes a height adjustment member. Among them, the first support member and / or the second support member is detachably connected to the seat body, and the height adjustment member is detachably provided between the first support member and / or the second support member and the seat body; alternatively, the first support member and / or the second support member includes a frame portion and a support portion, the support portion is detachably connected to the frame portion, and the height adjustment member is detachably provided between the frame portion and the support portion.

[0021] In the above technical solution, by adjusting the number of installed height adjustment members or adjusting the height of the installed height adjustment members, the height of the support member can be adjusted, so that the box support assembly can meet the matching requirements of different boxes, and the versatility of the box support assembly is stronger.

[0022] In some embodiments, the first support member extends in a first direction, and a plurality of the first support members are arranged in a second direction. The second support member is provided on both sides of the first support member along the first direction, and the first direction is perpendicular to the second direction.

[0023] In the above technical solution, the cooperation of a plurality of first support members can cooperate with different positions of the bottom plate in the first direction and the second direction, improving the support effect on the bottom plate. And the second support member is supported from both sides of the extending direction of the first support member, and the support is more stable.

[0024] In some embodiments, the seat body is provided with a first track that extends along the first direction. The first support member is installed on the first track, and in the first direction, the fixed position of the first support member on the first track is adjustable; the seat body is provided with a second track that extends along the second direction. The second support member is installed on the second track, and in the second direction, the fixed position of the second support member on the second track is adjustable.

[0025] In the above technical solution, by the cooperation of the first support member and the first track, the position of the first support member relative to the seat body in the first direction can be changed, so as to change the position of the first support member relative to the seat body in the length direction of the reinforcing beam. Furthermore, after the box support assembly is matched with the box, the first support member can be more matched with the position to be supported on the bottom plate, improving the support effect. By the cooperation of the second support member and the second track, the position of the second support member in the length direction of the side beam can be changed, so that the second support member can meet the side beam structure differences of different boxes.

[0026] In a second aspect, an embodiment of the present invention further provides a rubber pressing device, including a battery support assembly and the above box support assembly, and the battery support assembly is used to support the battery cell.

[0053] The term "a plurality of" as used in the present utility model means two or more (including two).

[0054] At present, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only applied to energy storage power systems such as hydraulic, thermal, wind and solar power stations, but also widely applied to electric transportation means such as electric bicycles, electric motorcycles and electric vehicles, as well as multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0055] In the present utility model, a battery refers to a single physical module including one or more battery cells to provide higher voltage and capacity. Some batteries may include a box for encapsulating one or more battery cells or multiple battery modules. The box can prevent liquids or other foreign objects from affecting the charging or discharging of the battery cells.

[0056] For example Figure 1As shown in the figure, in some electrical devices, a battery 2000 is used for power supply. The battery 2000 includes a box body 2200 and a plurality of battery cells 2100. The box body 2200 has a receiving cavity, and the plurality of battery cells 2100 are received in the receiving cavity of the box body 2200. Among them, the box body 2200 is used to provide a receiving cavity for the battery cells 2100, and the box body 2200 can adopt various structures. In some embodiments, the box body 2200 may include a first part 2210 and a second part 2220. The first part 2210 and the second part 2220 are covered with each other, and the first part 2210 and the second part 2220 jointly define a receiving cavity for receiving the battery cells 2100. The second part 2220 may be a hollow structure with one end open, and the first part 2210 may be a plate-like structure. The first part 2210 covers the open side of the second part 2220 so that the first part 2210 and the second part 2220 jointly define a receiving cavity; the first part 2210 and the second part 2220 may also both be hollow structures with one side open, and the open side of the first part 2210 covers the open side of the second part 2220. Of course, the box body 2200 formed by the first part 2210 and the second part 2220 can be in various shapes, such as a cylinder, a cuboid, etc.

[0057] Among them, the first part 2210 or the second part 2220 needs to be bonded to the battery cell 2100 through a structural adhesive 2260 to fix the battery cell 2100 and meet the structural strength requirements of the battery 2000. During the manufacturing process, first apply the structural adhesive 2260 on the bottom plate of the box body 2200 or the battery cell 2100, and then place the battery cell 2100 into the box body 2200. Use a pressure-applying device to apply a sufficiently large pressure (such as several tons of pressure) to make the structural adhesive 2260 uniform, with good bonding contact and sufficient bonding area.

[0058] Taking the example that the second part 2220 is bonded to the battery cell 2100 through the structural adhesive 2260, the second part 2220 includes a frame and a bottom plate. The frame is composed of a plurality of side beams 2230 connected end to end. The bottom plate includes a plate body 2240 and a reinforcing beam 2250. The reinforcing beam 2250 is arranged on the side of the plate body 2240 facing away from the receiving cavity, and the periphery of the plate body 2240 is connected to the frame. The side of the plate body 2240 facing the receiving cavity can be bonded to the battery cell 2100 through the structural adhesive 2260. During the manufacturing process of the related technology, a pressure-applying device applies pressure to the battery cell and the frame to achieve the bonding of the battery cell and the floor.

[0059] However, for some batteries, in order to improve the energy density, the thickness of the bottom plate of the box body is relatively small. For example, the thickness of the bottom plate of the CTP or CTC box body is less than 1 mm. Under the pressure of several tons, irreversible plastic deformation will occur in the bottom plate, resulting in unqualified overall dimensions of the battery and affecting the installation of the battery in the electrical device. Moreover, the larger the deformation of the bottom plate, the larger the concave pool formed on the glue application surface. To fill the concave pool, the consumption of structural adhesive will increase, and the manufacturing cost will increase. When the applied pressure is removed, the bottom plate may quickly rebound due to partial elastic deformation. The larger the deformation of the bottom plate, the greater the resilience, which is likely to cause the failure of the structural strength between the battery cell and the structural adhesive glass. During the use of the battery installed in the electrical device, vibration and other working conditions will cause the battery cell to fall off and the patch to peel off, resulting in product failure.

[0060] Based on this, the present application proposes a box body support assembly for a glue pressing device, including a seat body, a first support member, and a second support member. The first support member is installed on the seat body and is used to support the bottom plate of the box body; the second support member is installed on the seat body and is located on the outer periphery of the first support member, and the second support member is used to support the side beam of the box body.

[0061] In the battery with the above structure, the bottom plate of the box body is supported by the first support member, and the side beam of the box body is supported by the second support member. During the glue pressing process, the box body is not easily plastically deformed, which is beneficial to improving the overall dimensional accuracy of the battery, reducing the consumption of structural adhesive, and improving the bonding reliability between the battery cell and the box body, reducing the probability of peeling between the battery cell and the structural adhesive, and improving the structural strength.

[0062] The box body support assembly disclosed in the embodiments of the present application can be used for a glue pressing device. The glue pressing device is used for the glue pressing process between the battery cell and the box body during the battery production process. The box body support assembly is used for supporting the box body during the glue pressing process. The produced battery can be used for electrical devices using the battery as a power source or various energy storage systems using the battery as an energy storage element. The electrical device can be, but is not limited to, mobile phones, tablets, laptop computers, electric toys, power tools, battery cars, electric vehicles, ships, spacecraft, etc. Among them, the electric toy can include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric aircraft toys, etc. The spacecraft can include airplanes, rockets, space shuttles, and spaceships, etc.

[0063] Next, with reference to the drawings, the box body support assembly of the glue pressing device according to the embodiments of the present invention will be described.

[0064] Please refer to Figure 2 , Figure 2Schematic diagram of the mating structure of the glue pressing device 1000 and the battery 2000 provided by the embodiments of the present utility model. The box body support assembly 100 of the glue pressing device 1000 is used for the glue pressing process of the battery cell 2100 and the box body 2200. The box body support assembly 100 includes: a base body 10, a first support member 20, and a second support member 30.

[0065] Specifically, the first support member 20 is installed on the base body 10, and the first support member 20 is used to support the bottom plate of the box body 2200; the second support member 30 is installed on the base body 10 and is located on the outer periphery of the first support member 20, and the second support member 30 is used to support the side beam 2230 of the box body 2200.

[0066] The base body 10 is used to provide an installation site and support for the first support member 20 and the second support member 30, so that the first support member 20 and the second support member 30 are not prone to relative movement during the glue pressing process, which affects the glue pressing effect. The specific structure of the base body 10 can be flexibly set. For example, it can be a frame structure, a plate structure, or a combination structure of a frame and a plate, as long as it can realize the installation of the first support member 20 and the second support member 30. The connection method between the base body 10 and the first support member 20 and the second support member 30 is not limited, and can be, but is not limited to, fastener connection, welding, snap connection, etc.

[0067] During the glue pressing process, the relative orientation of the base body 10 and the support members (the first support member 20 and the second support member 30) can be flexibly set according to the actual situation. For example, in the glue pressing process of the battery cell 2100 being placed upright into the box, the opening of the box body 2200 faces upward, the battery cell 2100 moves downward into the accommodating cavity of the box body 2200, and the box body support assembly 100 can be located Figure 2 as shown on the lower side of the box body 2200, and the support members are located between the base body 10 and the box body 2200, so as to be in contact with the box body 2200 and provide an upward support force to the box body 2200. In the glue pressing process of the battery cell 2100 being placed upside down into the box, the battery cell 2100 is placed on the platform, and then the box body 2200 with the opening facing downward is buckled onto the battery cell 2100. The box body support assembly 100 can be located on the upper side of the box body 2200, and the support members are located between the base body 10 and the box body 2200, so as to be in contact with the box body 2200 and provide a downward support force to the box body 2200.

[0068] The box body 2200 includes a frame and a bottom plate. The periphery of the bottom plate is connected to the frame, so that the bottom plate and the frame cooperate to define a space for accommodating the battery cell 2100. The frame can include continuously extending side beams 2230, or as Figure 3 shown in a specific embodiment of the box body 2200, the frame is composed of a plurality of side beams 2230 connected end to end in sequence.

[0069] The first support member 20 may be one or more, and the second support member 30 may be one or more. The second support member 30 is located on the outer periphery of the first support member 20, which means that the first support member 20 is closer to the middle of the box body 2200 than the second support member 30. When the box body support assembly 100 supports the box body 2200, the first support member 20 can support the bottom plate, and the second support member 30 can support the side beam 2230.

[0070] During the glue pressing process, the second support member 30 can achieve support and positioning by cooperating with the side beam 2230, so that the box body 2200 is not easily moved or displaced to affect the glue pressing effect, and the side beam 2230 is not easily deformed irreversibly due to pressure; the first support member 20 can cooperate with the bottom plate to achieve support, so that the bottom plate is not easily deformed irreversibly due to excessive pressure. Especially for the bottom plate with a relatively thin plate thickness, the effect of reducing the plastic deformation of the bottom plate is better. Thus, the deformation of the bottom plate is smaller, the glue application surface of the bottom plate can avoid forming a concave pool or the formed concave pool is shallower, reducing the amount of structural glue 2260, so as to reduce the manufacturing cost; the deformation amount of the bottom plate is small, and after the glue pressing pressure is removed, the resilience of the bottom plate is small, so that it is not easy to peel between the bottom plate, the structural glue 2260 and the battery cell 2100, and the structural strength is high, which can meet the tests of working conditions such as vibration during subsequent use; the box body 2200 is not easily plastically deformed, and after the glue pressing is completed, the overall size of the battery 2000 is more likely to meet the design requirements, so that the battery 2000 can be installed and positioned in an electrical device such as a vehicle.

[0071] According to the box body support assembly 100 of the glue pressing device 1000 according to the embodiment of the present invention, the bottom plate of the box body 2200 is supported by the first support member 20, and the side beam 2230 of the box body 2200 is supported by the second support member 30, so that during the glue pressing process, the box body 2200 is not easily plastically deformed, which is beneficial to improving the overall dimensional accuracy of the battery 2000, reducing the amount of structural glue 2260, and improving the bonding reliability between the battery cell 2100 and the box body 2200, reducing the probability of peeling between the battery cell 2100 and the structural glue 2260, and improving the structural strength.

[0072] In some embodiments where the bottom plate of the box body 2200 includes a plate body 2240 and a reinforcing beam 2250, the reinforcing beam 2250 is disposed on the side of the plate body 2240 facing away from the accommodation cavity to strengthen the structural strength of the plate body 2240. The plate body 2240 is a plate structure with a large area and a thin thickness, and usually undergoes plastic deformation when deformed; the reinforcing beam 2250 usually has a cavity inside, and usually undergoes elastic deformation when undergoing a small deformation, that is, the elastic deformation of the reinforcing beam 2250 can rebound after the pressing glue pressure is removed. When undergoing a large deformation, it may cause the cavity to be compressed, the reinforcing beam 2250 undergoes plastic deformation, or a combination of elastic deformation and plastic deformation of the reinforcing beam 2250 occurs. The plastic deformation of the reinforcing beam 2250 has a greater impact on the installation and positioning of the battery 2000 in the electrical device.

[0073] Therefore, in some embodiments of the present invention, as Figure 2 shown, there are multiple first support members 20. Among the multiple first support members 20, at least one first support member 20 is a hard support member 21, and at least one first support member 20 is a soft support member 22. The hard support member 21 is used to support the plate body 2240 of the bottom plate, and the soft support member 22 is used to support the reinforcing beam 2250 of the bottom plate, and at least part of the soft support member 22 can be elastically deformed.

[0074] The hard support member 21 means that during the pressing glue process, this first support member 20 will not undergo obvious deformation. For example, the hard support member 21 can be made of materials with a relatively high hardness such as steel and alloy.

[0075] The soft support member 22 means that during the pressing glue process, this first support member 20 can partially undergo elastic deformation or can undergo elastic deformation as a whole. For example, the elastically deformable part of the soft support member 22 can be made of materials such as urethane rubber and rubber; in some embodiments, the Shore hardness of the elastically deformable part of the soft support member 22 can be 60 to 80 degrees, with a moderate hardness.

[0076] By using the hard support member 21 to support the plate body 2240, more stable support can be provided for the plate body 2240, reducing the deformation amount of the plate body 2240 during the pressing glue process, thereby effectively improving the plastic deformation problem of the plate body 2240. By using the soft support member 22 to support the reinforcing beam 2250, after the soft support member 22 undergoes elastic deformation, it can provide sufficient support for the reinforcing beam 2250 to reduce the deformation amount of the reinforcing beam 2250 and reduce the risk of plastic deformation; during the elastic deformation process of the soft support member 22, hard contact with the reinforcing beam 2250 can be avoided to absorb tolerances, thereby reducing the risk of plastic deformation caused by the compression of the cavity inside the reinforcing beam 2250. The plastic deformation amounts of the plate body 2240 and the reinforcing beam 2250 obtained after pressing glue are effectively reduced, and the overall dimensional accuracy of the battery 2000 is higher.

[0077] In some embodiments, asFigures 4 - 6 As shown Figures 4 - 6 Figures 4 - 6 is a schematic structural diagram of the box support assembly 100 provided by an embodiment of the present invention from different angles. The soft support member 22 includes a frame body portion 201 and a support portion 202. The frame body portion 201 is installed on the seat body 10, and the support portion 202 is installed on the frame body portion 201. The support portion 202 of the soft support member 22 is used to support the reinforcing beam 2250 and can be elastically deformed, and the hardness of the frame body portion 201 of the soft support member 22 is greater than that of the support portion 202.

[0078] The frame body portion 201 and the support portion 202 of the soft support member 22 can be made of the same material with different hardnesses, or can be made of different materials. For example, in some specific embodiments, the frame body portion 201 can be made of materials with greater hardness such as steel and alloy.

[0079] The support portion 202 of the soft support member 22 has a smaller hardness, so that the support portion 202 can undergo elastic deformation, effectively reducing the risk of plastic deformation of the reinforcing beam 2250; the frame body portion 201 of the soft support member 22 has a greater hardness, so that the frame body portion 201 can provide reliable support for the support portion 202, and thus the soft support member 22 as a whole can provide reliable support for the reinforcing beam 2250.

[0080] In some embodiments of the present invention, when the soft support member 22 is in an undeformed state, in the direction away from the seat body 10, the support surface of the soft support member 22 for supporting the reinforcing beam 2250 is higher than the support surface of the hard support member 21 for supporting the main body 2240 of the plate 210.

[0081] The undeformed state of the soft support member 22 means that the soft support member 22 is not in contact with the box body 2200 and is not under the pressure of the adhesive. The direction away from the seat body 10 is the direction close to the box body 2200, that is, the direction pointing from the box support assembly 100 to the box body 2200. The support surface of the soft support member 22 being higher than the support surface of the hard support member 21 means that the support surface of the soft support member 22 is closer to the box body 2200 than the support surface of the hard support member 21. In other words, before the box body 2200 contacts the box support assembly 100, the distance between the support surface of the soft support member 22 and the reinforcing beam 2250 is smaller than the distance between the support surface of the hard support member 21 and the main body 2240 of the plate.

[0082] Thus, during the adhesive pressing process, the support surface of the soft support member 22 first contacts the reinforcing beam 2250, and the soft support member 22 is compressed and elastically deformed, and then the support surface of the hard support member 21 contacts the main body 2240 of the plate. The reinforcing beam 2250 first contacts the box support assembly 100, so that the reinforcing beam 2250 with higher strength can share most of the pressure in advance, which is beneficial to reducing the pressure on the main body 2240 of the plate with lower strength and reducing the plastic deformation amount of the main body 2240 of the plate.

[0083] According to some embodiments of the present invention, such asFigure 2 As shown, the supporting surface of the rigid support member 21 near the middle of the plate body 2240 is the first supporting surface, and the supporting surface of the rigid support member 21 near the edge of the plate body 2240 is the second supporting surface. In the direction away from the seat body 10, the second supporting surface is higher than the first supporting surface.

[0084] Since the peripheral edge of the plate body 2240 is connected to the side beam 2230, during the glue pressing process, the deformation amount of the middle part of the plate body 2240 is greater than that of the edge of the plate body 2240. In the direction away from the seat body 10, the second supporting surface is higher than the first supporting surface, so that the distance between the second supporting surface and the edge of the plate body 2240 is substantially equal to the distance between the first supporting surface and the middle part of the plate body 2240. Different regions of the plate body 2240 are more evenly stressed, and thus are more evenly stressed, which is beneficial to improving the glue pressing uniformity of the structural adhesive 2260.

[0085] In some embodiments, please refer to Figures 5 - 7 , Figure 7 is Figure 6 the enlarged structural schematic diagram of the circled area A in

[0086] The supporting surface of the first support member 20 refers to the surface of the first support member 20 that is used to abut against the bottom plate during the glue pressing process. The avoidance area 203 can be an area that is recessed in the direction of approaching the seat body 10 on the supporting surface, that is, the avoidance area 203 is an area that is recessed away from the bottom plate on the supporting surface; or the avoidance area 203 can penetrate the first support member 20 in the direction of approaching the seat body 10. Compared with the recessed structure, the through-type structure has a larger extension dimension in the direction away from the supporting surface.

[0087] Thus, the avoidance area 203 can avoid the special-shaped structures on the bottom plate, including but not limited to areas such as protrusions, fasteners, and curved surfaces that are not easy to support. When the first support member 20 meets the support requirements for the bottom plate, it can reduce the influence of the special-shaped structures on the bottom plate. The structure of the first support member 20 is simpler, and it is easier to achieve the surface-to-surface contact between the first support member 20 and the bottom plate, improve the support stability, and reduce the production cost of the first support member 20.

[0088] In other embodiments, as Figures 5 - 7 shown, the first support member 20 includes a plurality of support bodies 204, and the plurality of support bodies 204 are arranged at intervals along the length direction of the reinforcing beam 2250 of the bottom plate. For example, the plurality of support bodies 204 of the same first support member 20 can be arranged at intervals along Figure 5 the first direction F1 shown.

[0089] Thus, a certain gap can be formed between two adjacent supports 204, and the extension dimension of this gap in the width direction of the reinforcing beam 2250 (such as Figure 5 the second direction F2 shown) is larger, increasing the area for avoidance, so as to form a better avoidance effect on the special-shaped structure on the reinforcing beam 2250 and other structures connected to the reinforcing beam 2250, which is more conducive to simplifying the structure of the first support 20 and reducing the manufacturing cost. For example, two adjacent reinforcing beams 2250 can be connected by a connecting beam extending along the second direction F2, and the gap between the two supports 204 of the first support 20 can be opposite to the connecting beam to avoid the connecting beam and the connection structure between the connecting beam and the reinforcing beam 2250.

[0090] In some other embodiments, the first support 20 can be provided with an avoidance area 203 and a plurality of supports 204 at the same time. For example, at least one support 204 can be provided with an avoidance area 203 to meet the structure avoidance requirements of the more complex reinforcing beam 2250.

[0091] According to some embodiments of the present invention, as Figure 6 and Figure 7 shown, the second support 30 is provided with a positioning pin 31, and the positioning pin 31 is used for plugging and positioning with the side beam 2230. For example, the side beam 2230 can be provided with a positioning hole, or the side beam 2230 is provided with an installation hole for installing the battery 2000, and the positioning pin 31 can be inserted into the positioning hole or the installation hole to achieve positioning.

[0092] By plugging the positioning pin 31 with the side beam 2230, positioning in the direction perpendicular to the caulking direction F3 can be achieved, such as positioning in the vertical direction, so that the relative position of the battery cell 2100 and the box body 2200 can be stable, and the relative position of the box body 2200 and the box body support assembly 100 can be stable. Thus, the assembly accuracy and bonding reliability of the battery cell 2100 and the box body 2200 after caulking are improved, and the support stability of the first support 20 for the box body 2200 is improved, and the effect of reducing the plastic deformation of the box body 2200 is better.

[0093] According to some embodiments of the present invention, as Figures 4 - 7 shown, at least one of the first support 20 and the second support 30 includes a frame part 201 and a support part 202. Among them, the support part 202 is detachably connected to the frame part 201, there are a plurality of support parts 202, and the plurality of support parts 202 are alternatively installed on the frame part 201, and at least one of the shapes, structures and support areas of the plurality of support parts 202 is different.

[0094] The support portion 202 of the first support member 20 is used to support the bottom plate, and the support portion 202 of the second support member 30 is used to support the side beam 2230. For the boxes 2200 of different batteries 2000, the shape, size, and structure of the bottom plate may vary, and the shape, size, and structure of the side beam 2230 may vary. For example, for different bottom plates, the number, arrangement position, and shape of the reinforcing beams 2250 on the plate body 2240 are different, and the shape, structure, and support area of the support surface of the corresponding first support member 20 may be different.

[0095] In the above embodiment, by detachably connecting the support portion 202 with the frame portion 201, and at least one of the shapes, structures, and support areas of the plurality of support portions 202 is different, during the application process, the matching support portion 202 can be replaced and installed on the frame portion 201 according to the differences in the required support for the bottom plate or the side beam 2230, so that the box support assembly 100 can meet the support requirements of different boxes 2200, and different boxes 2200 can adopt the same base 10 and frame portion 201, and only the support portion 202 needs to be replaced, which is beneficial to improving the versatility of the box support assembly 100 and reducing the production cost.

[0096] According to some embodiments of the present invention, as Figure 4 , Figure 6 and Figure 7 shown, the box support assembly 100 further includes a height adjusting member 40. Wherein, at least one of the first support member 20 and the second support member 30 is detachably connected to the base 10, and the height adjusting member 40 is detachably arranged between the first support member 20 and / or the second support member 30 and the base 10; or, at least one of the first support member 20 and the second support member 30 includes a frame portion 201 and a support portion 202, the support portion 202 is detachably connected to the frame portion 201, and the height adjusting member 40 is detachably arranged between the frame portion 201 and the support portion 202.

[0097] Here, the specific structure of the height adjusting member 40 can be flexibly set. The height adjusting member 40 can be a gasket. For example, the heights of a plurality of gaskets are different, and the height adjustment can be realized by replacing the height and number of the installed gaskets; or, the heights of a plurality of gaskets are the same, and the height adjustment can be realized by replacing the number of the installed gaskets; or, there is one gasket, and the height adjustment can be realized by installing and not installing the gasket; or, the height adjusting member 40 is a telescopic structure, and the height adjustment of the support member can be realized by adjusting the own length of the height adjusting member 40.

[0098] The height adjustment member 40 is provided between the support member and the seat body 10, or the height adjustment member 40 is provided between the frame body portion 201 and the support portion 202 of the support member, and the height of the support surface of the support member can be changed. By adjusting the number of the installed height adjustment members 40 or adjusting the height of the installed height adjustment members 40, the height adjustment of the support member can be achieved, so that the box body support assembly 100 can meet the matching requirements of different box bodies 2200, and the versatility of the box body support assembly 100 is stronger.

[0099] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the first support member 20 extends along the first direction F1, there are a plurality of first support members 20 arranged along the second direction F2, the second support members 30 are provided on both sides of the first support member 20 along the first direction F1, and the first direction F1 is perpendicular to the second direction F2.

[0100] The cooperation of a plurality of first support members 20 can cooperate with different positions of the bottom plate in the first direction F1 and the second direction F2, improving the support effect on the bottom plate. And the second support members 30 are supported from both sides of the extending direction of the first support member 20, and the support is more stable.

[0101] In some specific embodiments, such as Figure 3 As shown, the first direction F1 can be parallel to the length direction of the reinforcing beam 2250, and the second direction F2 is parallel to the arrangement direction of a plurality of reinforcing beams 2250. Thus, a plurality of first support members 20 can correspond to and support a plurality of reinforcing beams 2250 and the partial plate body 2240 between adjacent reinforcing beams 2250. Each first support member 20 can support a larger range in the length direction of the reinforcing beam 2250, or support a larger range in the length direction of the partial plate body 2240 between adjacent reinforcing beams 2250. Thus, the support effect of different regions of the entire bottom plate is improved.

[0102] In some embodiments, such as Figures 5 - 7 As shown, the seat body 10 is provided with a first track 11, the first track 11 extends along the first direction F1, the first support member 20 is installed on the first track 11, and in the first direction F1, the fixed position of the first support member 20 on the first track 11 is adjustable.

[0103] The specific structure of the first track 11 can be flexibly set. For example, the first track 11 can have a sliding groove extending along the first direction F1 (i.e., the length direction of the reinforcing beam 2250), the first support member 20 is slidably installed in the sliding groove, and can be locked with the first track 11 after the position adjustment is in place; again, for example, the first track 11 can have a plurality of installation positions arranged at intervals along the first direction F1, and the first support member 20 is alternatively installed in one of the installation positions to change the position of the first support member 20 on the seat body 10.

[0104] By cooperating the first support member 20 with the first track 11, the position of the first support member 20 relative to the seat body 10 in the first direction F1 can be changed, thereby changing the position of the first support member 20 relative to the seat body 10 in the length direction of the strengthening beam 2250. Furthermore, after the box support assembly 100 is cooperated with the box body 2200, the first support member 20 can be more matched with the position to be supported on the bottom plate, improving the support effect.

[0105] In some specific embodiments, the first support member 20 includes a plurality of support bodies 204. By adjusting the positions of the plurality of support bodies 204 on the first track 11, the distance between adjacent support bodies 204 can be adjusted to meet the avoidance requirements for special-shaped structures on different bottom plates.

[0106] In some embodiments, as Figures 5 - 7 shown, the seat body 10 is provided with a second track 12. The second track 12 extends along the length direction of the side beam 2230. The second support member 30 is installed on the second track 12, and in the extending direction of the second track 12, the fixed position of the second support member 30 on the second track 12 is adjustable.

[0107] The specific structure of the second track 12 can be flexibly set. It can be a track with a chute or can have a plurality of installation positions, which will not be elaborated here.

[0108] By cooperating the second support member 30 with the second track 12, the position of the second support member 30 in the length direction of the side beam 2230 can be changed. Furthermore, the second support member 30 can meet the structural differences of the side beams 2230 of different box bodies 2200. For example, the positions of the mounting holes on the side beams 2230 of different box bodies 2200 are different. By adjusting the position of the second support member 30, the second support member 30 can be positioned with the side beams 2230 of different box bodies 2200 through the positioning pins 31 and the mounting holes, and the versatility of the box support assembly 100 is stronger.

[0109] As Figure 2 shown, the rubber pressing device 1000 according to the second aspect embodiment of the present utility model includes a battery support assembly 200 and the box support assembly 100 according to the first aspect embodiment of the present utility model above. The battery support assembly 200 is used to support the battery cells 2100. Thus, by adopting the above box support assembly 100, during the rubber pressing process, the box body 2200 is not prone to plastic deformation, which is beneficial to improving the overall dimensional accuracy of the battery 2000, reducing the consumption of the structural adhesive 2260, and improving the bonding reliability between the battery cells 2100 and the box body 2200, reducing the probability of peeling between the battery cells 2100 and the structural adhesive 2260, and improving the structural strength.

[0110] In some embodiments, as Figure 2As shown, the battery support assembly 200 includes a support plate 210 and a pressing member 220. The support plate 210 is used to support the battery cell 2100, and the pressing member 220 is connected to the support plate 210 and is used to apply a pressure to the support plate 210 towards the box support assembly 100.

[0111] The pressing member 220 can be, but is not limited to, a cylinder, an electric cylinder, etc. By applying a pressure to the support plate 210 through the pressing member 220, and the support plate 210 can cooperate with a plurality of battery cells 2100, so that the forces on the plurality of battery cells 2100 are more uniform, thereby improving the uniformity and reliability of the bonding with the box 2200 through the structural adhesive 2260.

[0112] The battery 2000 production system according to the third aspect embodiment of the present invention includes the glue pressing device 1000 according to the second aspect embodiment of the present invention above. Thus, by adopting the above glue pressing device 1000, during the glue pressing process, the box 2200 is not prone to plastic deformation, which is beneficial to improving the overall dimensional accuracy of the battery 2000, reducing the amount of the structural adhesive 2260, and improving the bonding reliability between the battery cell 2100 and the box 2200, reducing the probability of peeling between the battery cell 2100 and the structural adhesive 2260, and improving the structural strength.

[0113] In some embodiments, the battery 2000 production system may further include a battery cell assembly device, a box assembly device, etc.

[0114] Next, the glue pressing device 1000 according to a specific embodiment of the present invention will be described with reference to the accompanying drawings.

[0115] As Figures 2 - 7 shown, the glue pressing device 1000 according to a specific embodiment of the present invention is used for the glue pressing process of the battery cell 2100 and the second part 2220 of the box 2200. The second part 2220 of the box 2200 includes a frame, a plate body 2240, and a plurality of reinforcing beams 2250. The frame includes four side beams 2230 connected end to end. The periphery of the plate body 2240 is connected to the four side beams 2230. The reinforcing beams 2250 extend along the width direction of the plate body 2240, and a plurality of reinforcing beams 2250 are spaced apart along the length direction of the plate body 2240 and are arranged on the lower side of the plate body 2240.

[0116] The glue pressing device 1000 includes a battery support assembly 200 and a box body support assembly 100. The battery support assembly 200 includes a support plate 210 and a plurality of pressing members 220. The box body support assembly 100 includes a base body 10, a plurality of hard support members 21, a plurality of soft support members 22, and a plurality of second support members 30. The hard support members 21, the soft support members 22, and the second support members 30 are all arranged on the upper side of the base body 10. The plurality of hard support members 21 and the plurality of soft support members 22 are alternately arranged along the length direction of the plate body 2240. The hard support members 21 are used to abut against the plate body 2240, and the soft support members 22 are used to abut against the reinforcing beam 2250. The second support members 30 cooperate with two side beams 2230 on both sides in the width direction of the plate body 2240, and each side beam 2230 cooperates with a plurality of second support members 30 arranged at intervals along the length direction of the plate body 2240.

[0117] During the glue pressing process, the second part 2220 of the box body 2200 is placed on the box body support assembly 100, and the positioning pins 31 of the second support members 30 are inserted into and cooperate with the side beams 2230 to achieve support and positioning; after applying structural glue 2260 on the upper surface of the plate body 2240, the battery cell 2100 is placed into the box body 2200, and a downward pressure is applied to the battery cell 2100 through the battery support assembly 200, so that the battery cell 2100 is fully bonded to the structural glue 2260. During the pressurization process, the plate body 2240 is supported by the hard support members 21, and the initial gap between the hard support members 21 and the plate body 2240 is L1; the reinforcing beam 2250 is supported by the soft support members 22, and the initial gap between the soft support members 22 and the reinforcing beam 2250 is L2, and L1 is greater than L2; the reinforcing beam 2250 first contacts the soft support members 22, so that the reinforcing beam 2250 shares most of the pressure in advance. The compression amount of the soft support members 22 during pressurization is L3, and the soft support members 22 make the downward concave deformation amount of the reinforcing beam 2250 less than or equal to L2 + L3. After pressurizing for a certain period of time, the pressure is removed, and after the battery cell 2100 and the box body 2200 rebound upward by a certain amount, the pressurization action is completed.

[0118] The battery 2000 assembled by using the caulking devices of the embodiment and the comparative example was subjected to a simulation test. In the embodiment, the caulking device was the caulking device 1000 of the above embodiment of the present application. The difference between the caulking device in the comparative example and that in the embodiment was that the hard support member 21 and the soft support member 22 were not provided. Under the same pressure, the downward convex deformation amount of the reinforcing beam 2250 after assembly using the embodiment was about 1 / 4 of that of the reinforcing beam 2250 after assembly using the comparative example, and the dimensional optimization of the battery 2000 was increased by 3 times. By using the assembly of the embodiment, the depth of the concave pool of the plate body 2240 was reduced by more than half, the amount of the structural adhesive 2260 could be reduced by more than 30%, and the reduction of the thickness of the structural adhesive 2260 could accelerate the curing time of the structural adhesive 2260, and the shortening of the static time of the product could improve the production rhythm. By using the assembly of the embodiment, the rebound displacement of the reinforcing beam 2250 was reduced, and the rebound force was synchronously reduced. Before the structural adhesive 2260 was cured, the problem of the degumming of the battery cell 2100 was greatly solved. The initial gap of the soft support member 22 was smaller than that of the hard support member 21. When the size of the reinforcing beam 2250 was out of tolerance, the soft support member 22 had a certain elasticity to absorb the tolerance, avoiding plastic deformation of the reinforcing beam 2250 caused by hard contact and affecting the installation positioning. The upper and lower heights of the hard support member 21, the soft support member 22 and the second support member 30 were adjustable, and the support size was adjustable. For product change, only the quick-change support part 202 was needed, and the compatibility of the caulking device 1000 was higher.

[0119] It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0120] The above are only the preferred embodiments of the present utility model, and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
