[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0045] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0046] In related technologies, battery packs mainly include battery trays and battery modules. The battery tray has a receiving cavity, and the battery module is housed in the receiving cavity. During assembly, adhesive is applied to the inner bottom surface of the battery module or the bottom wall of the receiving cavity. Pre-pressure is applied to the battery pack to spread the adhesive. Then, a pressure holding block is used to keep the adhesive under pressure for 4 to 6 hours until the adhesive cures, so that the battery module is bonded to the battery tray.

[0047] However, this pressing method results in poor bonding performance and a long cycle time. This is because the adhesive spreading pressure is low and cannot be adjusted. After the pre-pressure is removed, the adhesive becomes discontinuous due to the spreading pressure, leading to phenomena such as stringing, rebound, and detachment. This stringing and rebound not only damages the initial adhesive structure, causing deformed and discontinuous adhesive lines, but also reduces the bonding performance between the battery tray and the battery module, thereby lowering the stability and reliability of the battery pack and making it prone to quality problems such as detachment during subsequent use. Existing solutions also suffer from significant fluctuations in the pre-pressure range, making precise control difficult and compromising the consistency of pressure applied to different battery packs, thus affecting the stability of the pressing effect.

[0048] As battery packs become larger, battery trays also become larger, reducing the flatness of the battery trays. Existing technologies have not taken effective measures to address the issue of inconsistent flatness of incoming tray materials, making it impossible to guarantee uniform pressure on the adhesive when the flatness is poor.

[0049] In view of the above problems, this application provides a pressing device and a battery production equipment. The pressing device solves the problems of inaccurate control of adhesive spreading pressure, long curing time, stringing and rebound by synergistic design of pressure component and heating component, realizes uniform pressure and rapid curing of adhesive, and improves the efficiency and quality of battery pack production.

[0050] The following describes in detail, with reference to the accompanying drawings, the specific implementation methods of the adhesive bonding device and battery production equipment provided in this application.

[0051] Reference Figures 1 to 3 As shown in the figure, this application provides a battery production equipment, which includes a pressing device 10 and a splicing platform 20, with the pressing device 10 connected to the splicing platform 20.

[0052] It should be noted that the battery production equipment in this embodiment can assemble the various components of the battery pack. For example, the battery pack may include a battery tray 30 and battery modules, with the battery tray 30 used to carry and house the battery modules.

[0053] Since the battery production equipment includes a pressure bonding device 10 and a splicing platform 20, which are detachably connected, the splicing platform 20 can be used to support the battery tray 30 and the battery module during the battery pack production process, so that the battery tray 30 can be heated and pressurized by the pressure bonding device 10 to promote the curing of the adhesive. Thus, the battery production equipment can be used to bond the battery module and the battery tray 30.

[0054] Reference Figure 1 , Figure 4 and Figure 5 As shown, based on the above embodiments, this application also provides a pressing device 10. The pressing device 10 includes a first support 100, a heating component 200, and a pressure component 300. The first support 100, the pressure component 300, and the heating component 200 are arranged along a first direction (refer to the X direction in the figures). The pressure component 300 is connected to the first support 100, and the heating component 200 is connected to the pressure component 300. The pressure component 300 is configured to apply pressure to the heating component 200. The number of heating components 200 and pressure components 300 can be one or more, specifically determined according to the area of ​​the bottom surface of the battery tray 30.

[0055] In this embodiment, when the pressing device 10 is pressing the adhesive, it needs to move to the splicing platform 20 with the help of a crane or robotic arm to connect with the splicing platform 20. After the pressing is completed, the pressing device 10 needs to leave the splicing platform 20 with the help of a crane or robotic arm to facilitate the removal of the battery pack from the production line.

[0056] For example, the overhead crane can hoist the first bracket 100 to suspend the entire adhesive pressing device 10 onto the splicing platform 20, or to suspend the entire adhesive pressing device 10 away from the splicing platform 20. Alternatively, a robotic arm can grip the first bracket 100 to move the adhesive pressing device 10 to or away from the splicing platform 20.

[0057] The pressure-applying component 300 is used to apply uniform pressure to the adhesive, thereby spreading the linear or clump-like adhesive evenly between the battery tray 30 and the battery module, thus improving the bonding performance between the battery tray 30 and the battery module, and thereby improving the quality of the battery pack.

[0058] The heating component 200 is used to heat the battery tray 30 to accelerate the curing speed of the adhesive, thereby shortening the curing time of the adhesive and improving the production efficiency of the battery pack.

[0059] Since the pressurizing component 300 can apply pressure to the heating component 200, after the battery module and battery tray 30 are placed on the support platform, the heating component 200 is not activated at first. The pressurizing component 300 applies pressure to the heating component 200, and the pressure is transmitted to the battery tray 30, thereby causing the pressurizing component 300 to apply pressure to the battery tray 30 so that the adhesive is spread evenly. Then the heating component 200 is activated, and the pressurizing component 300 maintains pressure on the heating component 200 so that the heating component 200 heats and pressurizes the battery tray 30, thereby causing the adhesive to be heated while under pressure until the adhesive cures. The curing time of the adhesive can be shortened from 4 to 6 hours to within 1 hour.

[0060] Because the pressing device 10 can apply uniform pressure to the adhesive throughout the process, it avoids problems such as stringing and rebound delamination caused by discontinuous pressure, thereby improving the bonding quality of the adhesive. Furthermore, after uniform spreading, the pressing device 10 can heat the adhesive, thus increasing the curing speed. In this way, through the coordinated operation of the pressure application component 300 and the heating component 200, problems such as inaccurate adhesive spreading pressure control, long curing time, stringing, and rebound in related technologies can be solved, achieving uniform pressure and rapid curing of the adhesive, thereby improving the production efficiency and quality of battery packs. The pressing device 10 provided in this application embodiment includes a first support 100, a heating component 200, and a pressure application component 300. Since the pressing device 10 is provided with the first support 100, a transport mechanism such as a crane or robotic arm can be connected to the first support 100 to transport the pressing device 10 as a whole onto or away from the splicing platform 20. Because the bonding device 10 is equipped with a pressure-applying component 300, which can apply uniform pressure to the battery tray 30, the adhesive can be spread evenly, thereby ensuring uniform bonding between the battery module and the battery tray 30. Because the bonding device 10 is equipped with a heating component 200, which can heat the battery tray 30, the curing efficiency of the adhesive can be improved, thus shortening the bonding time between the battery tray 30 and the battery module. Because the pressure-applying component 300 can apply pressure to the heating component 200, the adhesive can be uniformly pressurized while being heated, thus avoiding problems such as stringing, rebound, and delamination of the adhesive, thereby improving the bonding quality of the battery pack. Therefore, the bonding device 10 of this embodiment can improve the bonding quality and efficiency of the battery pack.

[0061] Reference Figures 4 to 6 As shown, in one possible implementation, each heating assembly 200 includes an interconnected pressure plate 210, a heating element 220, and a pressure plate 230. The heating element 220 is located between the pressure plate 210 and the pressure plate 230. The pressure plate 230 is disposed close to the pressure assembly 300 relative to the pressure plate 210 and connected to the pressure assembly 300. The pressure plate 210 is configured to abut against the battery tray 30. The heating element 220 may be a thermocouple heating element 220.

[0062] With this configuration, the pressure applied by the pressurizing component 300 acts on the pressure plate 230, which then transmits the pressure to the adhesive plate 210. The adhesive plate 210 then applies pressure to the battery tray 30, thereby causing the pressurizing component 300 to apply pressure to the battery tray 30 through the heating component 200. The heating element 220 is positioned between the pressure plate 230 and the adhesive plate 210, which protects the heating element 220 from direct force and damage.

[0063] It should be noted that when the outer bottom surface of the battery tray 30 is flat, the pressure plate 210 can be set as a flat plate, and the pressure plate 210 can be in close contact with the outer bottom surface of the battery tray 30 to apply pressure evenly to various areas of the bottom surface of the battery tray 30.

[0064] If the outer bottom surface of the battery tray 30 is not flat, for example, when the bottom plate of the battery tray 30 is made of cold plate, the inner bottom surface of the battery tray 30 is flat, and the outer bottom surface of the battery tray 30 is an uneven surface, then the pressure plate 210 can be made into a contour plate, and a partition is set between the heating plate 220 and the pressure plate 210. Both the partition and the pressure plate 230 are flat plates. The heating plate 220 is sandwiched between the partition and the pressure plate 230 to protect the heating plate 220. The pressure plate 210 is matched with the outer bottom surface of the battery tray 30 so that the pressure plate 210 is in close contact with the outer bottom surface of the battery tray 30.

[0065] In other words, each heating component 200 may also include a partition, a pressure plate 210, a partition, a heating element 220 and a pressure plate 230 stacked in sequence and connected to each other.

[0066] Reference Figure 1 , Figure 4 , Figure 5 , Figure 7 As shown, in one possible implementation, each pressurization component 300 includes a second support 310 and a plurality of airbags 320, the plurality of airbags 320 being arranged along at least one of a second direction and a third direction, the plurality of airbags 320 being connected to the second support 310, and the second support 310 being connected to the first support 100.

[0067] The first direction, the second direction (refer to the Y direction in the attached figure), and the third direction (refer to the Z direction in the attached figure) are set perpendicular to each other.

[0068] It should be understood that multiple airbags 320 can be connected to the first support 100 via the second support 310, thereby integrating the pressurizing component 300 into the first support 100. When the airbags 320 are inflated, their volume expands, allowing them to apply pressure to the heating component 200, which in turn applies pressure to the battery tray 30. Since the pressure of the airbags 320 can be dynamically adjusted, the pressure on the adhesive remains stable during the accelerated curing process, achieving a dynamic balance between temperature and pressure, thus improving the bonding quality. Furthermore, the pressurization by the airbags 320 ensures greater consistency in the pressure applied to the adhesive in different areas of the battery tray 30, further enhancing the bonding effect.

[0069] For example, the airbag 320 can be made of thermoplastic polyurethane and can be made into a composite layer that can withstand pressure of 0.2 MPa or more.

[0070] Reference Figure 2 As shown, in one possible implementation, the pressurization assembly 300 further includes a diverter 330, which has an air inlet and several air outlets that are interconnected. The air outlets correspond one-to-one with the airbag 320 and are connected in communication. The air inlet is configured to be connected to an air source.

[0071] In this way, the compressed air provided by the air source can enter the splitter 330 through the air inlet and then enter the corresponding airbag 320 through the air outlet. This allows the air source to simultaneously provide compressed air to multiple airbags 320 through the splitter 330, thereby causing the airbags 320 to inflate and expand, thus providing dynamic pressure to the battery tray 30 through the airbags 320.

[0072] Reference Figure 5 As shown, in some embodiments, the pressurization assembly 300 further includes a plurality of first control valves 340, each of which is configured to correspond one-to-one with an air outlet. The first control valves 340 are located between the air inlet and the corresponding air outlet to control the on / off state between the air inlet and the air outlet.

[0073] In this way, before pressing the adhesive, the first control valve 340 can be closed to disconnect the air source and the airbag 320. When pressing the adhesive begins, the first control valve 340 can be opened to connect the air source and the airbag 320, thereby enabling the air source to provide compressed air to each airbag 320.

[0074] The first control valve 340 may include one or both of a solenoid control valve and a manual control valve. The solenoid control valve can achieve automatic control, while the manual control valve can achieve manual control and can be used when the solenoid control valve fails.

[0075] Reference Figure 5 As shown, in one possible implementation, the pressurization assembly 300 further includes a second control valve 350, which is configured to correspond one-to-one with the air outlet. The second control valve 350 is located between the air inlet and the corresponding air outlet to adjust the pressure state of the airbag 320.

[0076] In other words, the second control valve 350 can dynamically adjust the pressure of the airbag 320. When the adhesive is first applied, the airbag 320 is inflated, which in turn applies pressure to the battery tray 30. Then, the heating element 220 is controlled to heat the battery tray 30. During this process, some of the heat from the heating element 220 is conducted to the airbag 320, causing the airbag 320 to expand due to heat and increase its pressure. At this time, the second control valve 350 can control the airbag 320 to automatically depressurize, thereby preventing the airbag 320 from bursting due to excessive pressure. Thus, the design of the second control valve 350 can achieve a dynamic balance between the pressure and temperature of the adhesive.

[0077] For example, the pressure of the airbag 320 can be controlled between 5 and 20 kPa. If the pressure of the airbag 320 exceeds 20 kPa, the second control valve 350 can be opened to release pressure.

[0078] In one possible implementation, the pressure bonding device 10 further includes a control component, wherein the heating component 200 and the pressure component 300 are both electrically connected to the control component, and the control component is configured to control the heating component 200 to heat and the pressure component 300 to pressurize.

[0079] For example, at the beginning, a pressure management request is sent to the control component. After confirming that the pressurization component 300 can meet the pressure management request, the control component controls the first control valve 340 to open to inflate the airbag 320 until the pressure of the airbag 320 reaches a preset pressure range. The pressure of the airbag 320 is kept within the preset pressure range for a first preset duration. Then, a temperature management request is sent to the control component. After confirming that the pressurization component 300 can meet the pressure management request, the control component controls the heating element 220 to start until the temperature of the heating element 220 reaches a preset temperature range. The temperature of the heating element 220 is kept within the preset temperature range for a second preset duration.

[0080] Reference Figure 2 , Figure 4 and Figure 7 As shown, in one possible implementation, the pressurization assembly 300 further includes a plurality of connectors 360 connected to both sides of the second bracket 310 along a second direction. The connectors 360 are configured to be detachably connected to the splicing platform 20 of the battery production equipment. The first bracket 100 has a lifting section 110 configured to be connected to a crane.

[0081] Thus, after the battery module and battery tray 30 are installed onto the splicing platform 20, a crane can be connected to the hoisting unit 110 to transport the pressing device 10 onto the splicing platform 20. Then, the second bracket 310 and the splicing platform 20 are locked by the connector 360, thereby realizing the installation of the pressing device 10 and the splicing platform 20. This facilitates pressing the battery tray 30 with the pressing device 10. After pressing is completed, the second bracket 310 and the splicing platform 20 are unlocked by unlocking the connector 360. The crane can then be connected to the hoisting unit 110 to move the pressing device 10 away from the splicing platform 20, thus facilitating the removal of the battery pack from the production line.

[0082] For example, connector 360 can be a quick-release caliper, screw, or pin.

[0083] Reference Figure 5 and Figure 7 As shown, in some embodiments, the pressurizing component 300 further includes an elastic element 370, the second bracket 310 is provided with a guide post 311, the guide post 311 is movably connected to the heating component 200 along a first direction, the elastic element 370 is sleeved on the guide post 311, and the elastic element 370 is elastically connected between the second bracket 310 and the heating component 200.

[0084] Thus, by setting an elastic element 370 between the second bracket 310 and the heating component 200, a flexible connection between the pressure component 300 and the heating component 200 can be achieved. Impacts along the first direction can be absorbed by the elastic element 370, thereby enabling the pressure bonding device 10 to have good operability and achieve effective protection of the bottom surface of the battery tray 30.

[0085] In one possible implementation, the pressure bonding device 10 includes a pressure assembly 300, which includes a second bracket 310 and a connector 360. The second bracket 310 is detachably connected to the splicing platform 20 via the connector 360.

[0086] Thus, by setting the second bracket 310 and the connector 360, the pressure bonding device 10 can be easily assembled and disassembled with the splicing platform 20, thereby enabling the battery production equipment to dock and bond the battery tray 30 and the battery module.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
