Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to a hot stamping device and sheet material processing equipment. Background Technology

[0002] In the field of battery manufacturing, the processing of sheet materials such as copper foil is a crucial step in the formation of battery cell structures. These materials typically undergo multiple processes, including bending, cutting, and welding, and their physical properties directly affect the precision of the process and the quality of the finished product. Because the sheet material itself needs to possess a certain mechanical strength to support the battery structure, it often exhibits high rigidity in its natural state. While this characteristic is beneficial for material transportation and stacking, it can become an obstacle in the process of fine processing, increasing the complexity of process control.

[0003] In existing technologies, the processing of sheet materials such as copper foil mainly relies on the direct action of mechanical external force, such as bending by die stamping, cutting by cutting tools, or forming a connection by high-pressure welding.

[0004] While such methods can achieve basic processing goals, they often require significant external force due to the inherent strength of the materials, leading to increased equipment load and energy consumption. Furthermore, high-strength materials are prone to stress concentration during stress, causing uneven local deformation and further contributing to decreased processing consistency. Utility Model Content

The hot ironing head is connected to the mounting base. The driving end of the second driving member is connected to the mounting base and is adapted to drive the hot ironing head to move closer to or away from the platform structure along the third direction. The side of the hot iron head facing the platform structure along the third direction is the hot iron surface. The length direction of the hot iron surface is parallel to the first direction, and the first direction, the second direction, and the third direction intersect each other.

[0015] Beneficial effects: The platform structure and the hot ironing head form a gap to allow the sheet material to pass through.

The axial direction of the limiting rollers is parallel to the first direction. The side of the platform structure facing the hot iron head along the third direction is the contact surface. The generatrix of the lowest end of the peripheral surface of the limiting roller along the third direction is located on the same horizontal plane as the contact surface of the platform structure.

[0021] Beneficial effects: By placing a pair of limiting rollers at both ends of the platform structure, the sheet material is guided smoothly through the second channel.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following is combined Figures 1 to 12 This describes an embodiment of the present application.

[0031] According to an embodiment of this application, in one aspect, a hot ironing device is provided, having intersecting first direction X and second direction Y, including a housing 1, a first hot ironing component 100, a second hot ironing component 200 and a control component.

[0032] The housing 1 is provided with a receiving cavity 101. The first heat-pressing assembly 100 includes a heat-pressing roller 11 and multiple heat-pressing rings 110. The heat-pressing roller 11 has a cavity, and its axial direction is parallel to the first direction X. The multiple heat-pressing rings 110 are spaced apart within the cavity along the axial direction of the heat-pressing roller 11. The second heat-pressing assembly 200 includes multiple heat-pressing heads 231, which are spaced apart along the second direction Y. A control assembly is electrically connected to the multiple heat-pressing rings 110 and the multiple heat-pressing heads 231, and is adapted to control the start and stop of each heat-pressing ring 110 and each heat-pressing head 231. Both the first heat-pressing assembly 100 and the second heat-pressing assembly 200 are disposed within the receiving cavity 101 and are sequentially distributed along the second direction Y. The sheet material 300 passes sequentially through the first heat-pressing assembly 100 and the second heat-pressing assembly 200 within the receiving cavity 101.

[0033] It should be noted that the cavity of the hot stamping roller 11 is provided with multiple individually heatable and controllable hot stamping rings 110 arranged along its axial direction to form a continuous targeted heating area on the path of the sheet material 300 traveling in the second direction Y. Because the hot stamping roller 11 heats the sheet material 300 through the split hot stamping ring 110 structure, heat can be precisely concentrated on the hot stamping rings 110, and heat is not easily transferred to other non-heated areas on the hot stamping roller 11. On the one hand, it can precisely control the temperature of specific targeted areas on the sheet material 300, avoiding the reduction of strength and impact on its strength performance by heating non-processed areas of the sheet material 300 that do not require strength reduction. On the other hand, each hot stamping ring 110 can be individually heated and controlled; specific heating rings can be selected to be activated according to processing needs, while other heating rings do not need to be activated. This allows for the formation of a flexible and controllable targeted heating area on the sheet material 300 according to different requirements.

[0034] Understandably, the second direction Y can be the length direction of the sheet material 300, the first direction X can be the width direction of the sheet material 300, and the third direction Z can be a direction perpendicular to the ground. The first direction X, the second direction Y, and the third direction Z can be set to be mutually perpendicular.

[0035] Optionally, the circumferential surface of the hot stamping ring 110 abuts against the inner wall of the hot stamping roller 11. Alternatively, thermally conductive adhesive can be provided between the circumferential surface of the hot stamping ring 110 and the inner wall of the hot stamping roller 11. This ensures that heat is directly transferred to the sheet material 300, avoids heat loss, affects the heating effect, and reduces energy consumption.

[0036] Optionally, an insulation layer can be provided on the wall of the box 1. Specifically, the insulation layer can be made of insulation cotton.

[0037] In this embodiment, by setting up a housing 1, a first heat-pressing component 100, a second heat-pressing component 200, and a control component, directional heat treatment of specific areas of the sheet material 300 is achieved. The first heat-pressing component 100 is used for continuous targeted heat pressing, and the second heat-pressing component 200 is used for intermittent targeted heat pressing. The two are distributed sequentially along the second direction Y. The control component independently controls the start and stop of the heat-pressing ring 110 and the heat-pressing head 231, thereby flexibly reducing the strength of specific areas of the sheet material 300, realizing the differentiation of strength levels in different areas, facilitating subsequent processing, effectively solving the processing difficulties and abnormal problems caused by the high strength of the sheet material 300, and improving processing accuracy and adaptability.

[0038] In one embodiment, the first heat-pressing assembly 100 further includes a sheet pressing member 12, which includes a pressing sheet 122 and a pair of pressing rollers 121. The pressing sheet 122 has an arc-shaped surface that is adapted to the circumferential surface of the heat-pressing roller 11, forming a first channel between the arc-shaped surface and the heat-pressing roller 11 for the sheet material 300 to pass through. The pair of pressing rollers 121 are respectively disposed on both sides of the pressing sheet 122 along the second direction Y, and the axial direction of the pressing rollers 121 is parallel to the first direction X. The pressing sheet 122 and the pressing rollers 121 are adapted to move closer to or further away from the heat-pressing roller 11 along the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0039] It should be noted that the sheet pressing component 12 can selectively press the sheet 300 onto the surface of the hot stamping roller 11. When the sheet 300 as a whole does not require targeted hot stamping, the sheet pressing component 12 can choose not to press the sheet 300 onto the surface of the hot stamping roller 11. This avoids the temperature or residual heat on the hot stamping roller 11 heating the sheet 300, which would reduce the strength of the non-processed areas of the sheet 300 that do not require strength reduction, thus affecting its strength performance. By setting the split hot stamping ring 110 structure and the sheet pressing component 12, precise heating of specific areas of the metal sheet 300 is achieved, avoiding heating of non-targeted areas and affecting the strength of the sheet 300. Combined with the selective pressing action of the sheet pressing component 12, the stability and consistency of the heat treatment process are ensured, effectively reducing the material strength of the target area.

[0040] Understandably, when the pressure roller 121 is above the sheet 300 and the heat-pressing roller 11 is below the sheet 300, and neither is in contact with the sheet 300, the sheet 300 as a whole is not affected by the temperature on the heat-pressing roller 11. When the two pressure rollers 121 press down and drive the sheet 300 to move downward, the sheet 300 between the two pressure rollers 121 comes into contact with the heat-pressing roller 11 during the downward movement, forming a "W"-shaped travel path, and part of the sheet 300 is tightly attached to the surface of the heat-pressing roller 11 under the action of the pressure roller 121, and is continuously targeted heat-pressed by the heat-pressing roller 11.

[0041] Optionally, the curved surface of the pressing plate 122 is fitted to the sheet material 300, increasing the pressure area of ​​the sheet material 300 and enhancing the adhesion between the sheet material 300 and the hot stamping roller 11, thereby ensuring the hot stamping effect. The full pressing of the pressing plate 122 effectively avoids problems such as wrinkling and deformation of the sheet material 300 caused by uneven local stress during the hot stamping process, ensuring the flatness and surface quality of the sheet material 300. At the same time, this structural design makes the tension distribution of the sheet material 300 in the hot stamping area more uniform, further improving the consistency and stability of heat treatment and providing quality assurance for subsequent processing steps.

[0042] In this embodiment, the pressing plate 122 has an arc-shaped surface that forms a first channel with the hot stamping roller 11 for the sheet material 300 to pass through, which can ensure that the sheet material 300 is in close contact with the hot stamping roller 11, improve heat conduction efficiency and heat stamping uniformity. The pressure roller 121 guides the sheet material 300 to move stably, reduces the offset or wrinkles of the sheet material 300, and enhances processing consistency and quality. At the same time, by adjusting the position of the pressing plate 122 and the pressure roller 121 along the third direction Z, the sheet material 300 can be in close contact with the arc-shaped surface.

[0043] In one embodiment, such as Figure 10 As shown, the sheet pressing component 12 also includes a first connecting component 124. The pressing roller 121 is provided with the first connecting component 124 at both ends along its axial direction. The pressing sheet 122 is provided with a folding structure 123 at both ends along the second direction Y. The pressing roller 121 is located on the side of the folding structure 123 facing the hot heat roller 11 along the third direction Z. The end of the folding structure 123 along the first direction X is connected to the first connecting component 124.

[0044] It should be noted that the first connecting member 124 is configured as a plate structure, and the first connecting member 124 has threaded holes and is connected to the end of the pressure roller 121 and the driving end of the first driving member 14 by bolts respectively.

[0045] The folded edge structure 123 can be understood to extend outward from both ends along the first direction X, thereby connecting with the top surface of the first connector 124.

[0046] In this embodiment, the pressure roller 121 and the pressing sheet 122 are connected by the first connector 124, which can enhance the mechanical stability and rigidity of the sheet pressing component 12, ensure that the pressing sheet 122 and the pressure roller 121 move in tandem, reduce vibration and offset, improve the reliability and durability of the hot stamping process, reduce maintenance requirements, and thus ensure the stability of long-term operation.

[0047] In one embodiment, the sheet pressing member 12 further includes a first driving member 14 disposed on at least one side along the axial direction of the pressing roller 121. The first driving member 14 is connected to the first connecting member 124. The driving end of the first driving member 14 is adapted to drive the sheet pressing member 122 and the pressing roller 121 to move closer to or away from the hot heat roller 11 along the third direction Z.

[0048] It should be noted that the first driving member 14 is a rodless cylinder. The guide portion of the rodless cylinder is arranged vertically on at least one side of the pressure roller 121 along the axial direction. The pressure roller 121 is rotatably connected to the driving block 142 of the rodless cylinder through the first connecting member 124.

[0049] Optionally, the first driving component 14 may also be configured as a driving cylinder.

[0050] In this embodiment, the first driving member 14 drives the pressing plate 122 and the pressing roller 121 to move along the third direction Z, which can realize the automatic adjustment of the position of the pressing plate 122 and the pressing roller 121, improve the automation level and operation convenience of the device, reduce manual adjustment time, and improve production efficiency and processing flexibility.

[0051] In one embodiment, the sheet pressing component 12 further includes a slide rail, which is vertically disposed on at least one side of the pressing roller 121 along its axial direction. The pressing roller 121 is rotatably connected to a slider slidably disposed on the slide rail. The slide rail mechanism provides precise guidance for the pressing roller 121, ensuring the smoothness and repeatability of the lifting process, while also having the advantages of simple structure and convenient maintenance.

[0052] In one embodiment, the second heat-pressing assembly 200 further includes a platform structure 22 and a drive assembly 23. The platform structure 22 and the heat-pressing head 231 are spaced apart along a third direction Z, and the gap between the heat-pressing head 231 and the platform structure 22 forms a second channel, suitable for the sheet material 300 to pass through along a second direction Y. The drive assembly 23 includes a second drive member 233 and a mounting base 232. The mounting base 232, the heat-pressing head 231, and the platform structure 22 are sequentially distributed along a third direction Z. The heat-pressing head 231 is connected to the mounting base 232, and the drive end of the second drive member 233 is connected to the mounting base 232, suitable for driving the heat-pressing head 231 to move closer to or away from the platform structure 22 along the third direction Z. The side of the heat-pressing head 231 facing the platform structure 22 along the third direction Z is the heat-pressing surface, and the length direction of the heat-pressing surface is parallel to the first direction X. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0053] It should be noted that the platform structure 22 is fixedly installed in the receiving cavity 101 to support and guide the movement of the sheet material 300. The mounting base 232 is located above the platform structure 22. Each heating head 231 is spaced apart and can be individually controlled to heat and press down, so as to target and heat specific positions of the sheet material 300.

[0054] Specifically, the sheet material 300 can pass through the second channel between the heating head 231 and the platform structure 22. When the area to be processed on the sheet material 300 passes under the corresponding heating head 231, the heated heating head 231 can be controlled to press down, performing targeted heating on the specific area to be processed on the sheet material 300. This causes the corresponding area to be heated and its strength to decrease, while the strength of other areas remains unchanged. Furthermore, to ensure processing efficiency and avoid the time-consuming intermittent movement of the sheet material 300 due to heating, multiple heating heads 231 are included. Multiple heating heads 231 can work together to heat the targeted area on the sheet material 300, so that multiple areas can be heated separately in one heating process, improving heating efficiency.

[0055] In this embodiment, the platform structure 22 and the hot ironing head 231 form a gap to allow the sheet material 300 to pass through. The second driving member 233 controls the hot ironing head 231 to press down intermittently for targeted hot ironing, thereby accurately reducing the intensity of a specific area of ​​the sheet material 300, avoiding the influence on non-target areas, improving the hot ironing positioning accuracy and processing consistency, and adapting to different processing requirements by adjusting the position of the hot ironing head 231.

[0056] In one embodiment, the drive assembly 23 further includes a second connector 237 and a crossbeam structure 234. The second connector 237 includes a first end and a second end opposite to each other. A strip-shaped hole 2321 is provided on the side of the mounting base 232 away from the heating head 231 along a third direction Z. The strip-shaped hole 2321 extends along a second direction Y. The second connector 237 passes through the strip-shaped hole 2321 along the third direction Z, and the first end of the second connector 237 is connected to the heating head 231. The crossbeam structure 234 extends along a first direction X and is connected to the second end of the second connector 237. The crossbeam structure 234 is slidably mounted on the mounting base 232 along the second direction Y. Multiple second connectors 237 and multiple crossbeam structures 234 are provided, and each pair of second connectors 237, multiple crossbeam structures 234, and multiple heating heads 231 are respectively provided in a one-to-one correspondence.

[0057] It should be noted that the mounting base 232 and the strip hole 2321 provide mechanical guidance for the movement of the second connector 237, ensuring a smooth and precise movement process, avoiding positional deviations, and further improving machining accuracy.

[0058] In this embodiment, by providing the second connector 237 and the crossbeam structure 234, the hot ironing head 231 can slide along the second direction Y. This structure allows for flexible adjustment of the lateral position of the hot ironing head 231, facilitating targeted processing of different areas of the sheet material 300, enhancing the flexibility and coverage of the hot ironing, improving the adaptability of the device to complex processing patterns, and meeting diverse production requirements.

[0059] In one embodiment, the drive assembly 23 further includes a base 235 and a third drive member 236. The base 235 is disposed on the side of the platform structure 22 away from the hot iron head 231 along the third direction Z. The second drive member 233 is disposed on the base 235, and its drive end passes through the platform structure 22 and is connected to the mounting base 232. The third drive member 236 is disposed on the base 235, and its drive end is connected to the platform structure 22. The drive end of the third drive member 236 is adapted to drive the platform structure 22 away from or towards the hot iron head 231 along the third direction Z.

[0060] It should be noted that the drive assembly 23 also includes a fixed vertical guide rail 27, with the platform structure 22 and mounting base 232 movably engaging with the vertical guide rail 27. The vertical guide rail 27 enables flexible adjustment of the platform structure 22 and mounting base 232 in the height direction, allowing the device to adapt to the processing of sheets 300 of different thicknesses, enhancing the versatility and adaptability of the equipment, simplifying equipment debugging and changeover processes, and reducing operating costs.

[0061] In this embodiment, a base 235, a second drive member 233, and a third drive member 236 are added to drive the platform structure 22 and the hot ironing head 231 to move. The base 235 provides stable support, the second drive member 233 controls the hot ironing head 231 to press down, and the third drive member 236 adjusts the platform position, thereby precisely controlling the hot ironing gap and pressure, ensuring the uniformity and consistency of hot ironing, improving processing quality and equipment reliability, while reducing energy consumption and operational complexity.

[0062] In one embodiment, such as Figures 7 to 9 As shown, the end of the crossbeam structure 234 is provided with an indicator structure 238, and a scale 24 is fixedly installed on the mounting base 232. The indicator structure 238 and the scale 24 cooperate to position the hot iron head 231.

[0063] In this embodiment, the cooperation between the indicator structure 238 and the scale 24 provides an intuitive and precise positioning method, ensuring the accurate and controllable position of the hot iron head 231, facilitating the adjustment of the position of the hot iron head 231 during the production process, and ensuring the stable quality of batch products.

[0064] In one embodiment, such as Figure 11 and Figure 12As shown, the second connector 237, the crossbeam structure 234, and the hot iron head 231 constitute a hot ironing unit 28, and at least three hot ironing units 28 are provided along the second direction Y. The crossbeam structure 234 in the hot ironing unit 28 located in the middle position is a positioning crossbeam 281, and a positioning seat 283 is provided at the end of the positioning crossbeam 281 along the first direction X. The crossbeam structures 234 in the hot ironing units 28 located at both ends are movable crossbeams 282, and movable seats 284 are provided at the end of the movable crossbeams 282 along the first direction X. The movable seats 284 and the positioning seats 283 are distributed sequentially along the second direction Y. A first through hole is provided on the positioning seat 283, and a second through hole is provided on the movable seat 284. A screw 29 is inserted through the first through hole, and the screw 29 is rotatably connected to the first through hole. Both ends of the screw 29 are respectively threadedly connected to the second through hole, and the screw 29 is configured as a bidirectional screw 29. The threads at both ends of the screw 29 are opposite in direction. By rotating the screw 29, the two movable seats 284 can be moved away from the positioning seat 283 along the second direction Y, which can make the spacing between the two adjacent hot ironing units 28 adjustable, and thus the position of the hot ironing head 231 can be adjusted.

[0065] Optionally, drive structures 291 can be provided at both ends of the screw 29 to drive the screw 29.

[0066] Specifically, the drive structure 291 can be configured as a turntable, which allows the operator to adjust the spacing between multiple heating heads 231 by turning the turntable, or it can be driven directly by a motor. The drive structure 291 can also be configured as a gear structure, with a drive gear connected to the motor drive end. The drive gear meshes with the gear structure to drive the screw 29.

[0067] In one embodiment, such as Figure 11 and Figure 12 As shown, the second connector 237, the crossbeam structure 234, and the hot iron head 231 constitute a hot ironing unit 28, and multiple hot ironing units 28 can be arranged along the second direction Y. A fixing seat can be connected to the top end of each crossbeam structure 234. Multiple fixing seats are distributed sequentially along the second direction Y, and each fixing seat has a through hole, with the through holes corresponding to each other along the second direction Y. By setting a screw 29 to pass through multiple through holes simultaneously, and with a clearance fit between the circumferential surface of the screw 29 and the through holes, the fixing seat can slide along the axial direction of the screw 29 to adjust its position along the second direction Y. Each fixing seat has two nuts, and the nuts are threadedly connected to the screw 29. The nuts located on both sides of the fixing seat can position the fixing seat. By manually turning the nuts on the screw 29, the distance between two adjacent hot ironing units 28 can be adjusted, thereby adjusting the position of the hot iron head 231.

[0068] In one embodiment, the second hot ironing assembly 200 further includes a pair of limiting rollers 4, which are respectively disposed at both ends of the platform structure 22 along the second direction Y. The axial direction of the limiting rollers 4 is parallel to the first direction X. The side of the platform structure 22 facing the hot ironing head 231 along the third direction Z is the contact surface. The generatrix of the lowest end of the peripheral surface of the limiting rollers 4 along the third direction Z is located on the same horizontal plane as the contact surface of the platform structure 22.

[0069] In this embodiment, a pair of limiting rollers 4 are set at both ends of the platform structure 22 to guide the sheet material 300 smoothly through the second channel. The limiting rollers 4 can prevent the sheet material 300 from deviating or sagging, ensure that the hot stamping head 231 accurately acts on the target area, improve processing accuracy and sheet material 300 transmission stability, reduce processing defects, and enhance the overall operating efficiency of the equipment.

[0070] In one embodiment, the device further includes a cooling roller 3. The first heat-pressing component 100 is provided with a first feeding end and a first discharging end at both ends along the second direction Y. The second heat-pressing component 200 is provided with a second feeding end and a second discharging end at both ends along the second direction Y. The first discharging end and the second discharging end are both provided with a cooling roller 3.

[0071] Optionally, a heat exchange pipeline is also provided, which is at least connected between the hot roller 11 and the cooling roller 3. The refrigerant in the heat exchange pipeline releases heat at the hot roller 11 and absorbs heat at the cooling roller 3. The heat exchange pipeline enables the recycling of heat energy within the system, which not only improves energy efficiency but also optimizes the heat treatment process parameters through precise temperature control, thereby enhancing product quality stability.

[0072] In this embodiment, the cooling roller 3 can quickly cool the hot-stamped sheet 300, which is equivalent to annealing. This fixes the hot-stamping effect, prevents the sheet 300 from deforming or losing strength due to residual heat, ensures the stability of the area with reduced strength, facilitates subsequent processing steps, and improves the overall process continuity and product quality.

[0073] According to an embodiment of this application, another aspect provides a sheet material processing device 1000, including a heat treatment device, an unwinding assembly 1001, and a winding assembly 1002. The housing 1 of the heat treatment device is provided with an inlet 111 and an outlet 112. The unwinding assembly 1001 is disposed on the outside of the housing 1 near the inlet 111, and the winding assembly 1002 is disposed on the outside of the housing 1 near the outlet 112.

[0074] It should be noted that the sheet material 300 is wound between the unwinding assembly 1001 and the winding assembly 1002, and moves inside the insulation box 1 under the drive of the unwinding assembly 1001 and / or the winding assembly 1002.

[0075] Optionally, a sheet material 300 storage section is provided between the unwinding assembly 1001 and / or the winding assembly 1002 and the housing 1.

[0076] In this embodiment, continuous automated production of sheet material 300 from unwinding, heat treatment to rewinding can be realized. It integrates the targeted processing advantages of the heat treatment device, improves production efficiency, reduces labor costs, and ensures the consistency and quality of sheet material 300 processing.

[0077] In one embodiment, the receiving cavity 101 is filled with a protective gas, and a sealing brush is provided at the inlet 111 and / or outlet 112. The combination of the protective gas environment and the sealing brush effectively prevents outside air from entering the receiving space, avoiding the oxidation problem of the metal sheet 300 at high temperatures, ensuring the quality of the heat-treated surface, and reducing the consumption of protective gas.

[0078] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
