Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum foil hot stamping technology, and in particular to an electroplated aluminum conveying anti-sticking system. Background Technology

[0002] In the electroplated aluminum foil hot stamping process, the stable transport of the electroplated aluminum foil is a crucial step in ensuring stamping quality and production efficiency. The guide rod, as a core component in the transport path, primarily supports the electroplated aluminum foil and guides its movement along a pre-set path. Especially when handling special substrates such as honeycomb panels, due to the substrate's structural characteristics, the electroplated aluminum foil needs to undergo multiple large-angle turns to adapt to the stamping surface. At these points, the guide rod in the corner area must withstand greater foil tension and contact pressure, becoming a critical node in the transport process.

[0003] However, in existing technologies, guide rods used for large-angle steering are mostly smooth metal rods, and their contact with the electroplated aluminum foil is direct physical contact. In actual production, because the surface of the electroplated aluminum foil is usually coated with a hot-melt coating (such as a metal layer or adhesive layer), it is subjected to tension during transmission. The contact pressure between the foil and the guide rod in the corner area is relatively high, and the friction time is relatively long. This makes it very easy for the foil to adhere to the surface of the guide rod due to local temperature rise (frictional heat generation) or slight melting of the coating, resulting in adhesion. This adhesion problem is particularly prominent when processing thin electroplated aluminum foil or foil with high adhesion coating.

[0004] The aforementioned adhesion problem directly caused a series of production pain points:

[0005] Frequent manual intervention: To remove adhesion, operators need to frequently stop the machine and manually pull the electroplated aluminum foil. This is not only cumbersome and labor-intensive, but also poses a safety hazard of being scratched or burned because it requires contact with high-speed transmission components and the high-temperature hot stamping area. At the same time, manual intervention will directly interrupt the continuous production process and disrupt the stability of the transmission path.

[0006] Damaged foil: Forcibly pulling and sticking together electroplated aluminum foil can easily lead to uneven tension distribution, causing local wrinkling, stretching deformation or even breakage. This not only wastes foil but also causes quality problems such as blurry, misaligned or incomplete hot stamping patterns due to foil morphological defects, which seriously affects the product qualification rate.

[0007] Low production efficiency: The adhesion problem causes the equipment to be stopped frequently for maintenance, which significantly shortens the effective operating time. According to actual production data, the equipment has a long downtime for maintenance and low production efficiency due to the adhesion problem of the corner guide rod alone.

[0008] Therefore, the existing guide rod structure can hardly meet the stable transmission requirements of electroplated aluminum foil in large-angle turning scenarios. There is an urgent need for a technical solution that can effectively prevent electroplated aluminum foil from sticking to the guide rod, so as to solve the problems of frequent manual intervention, large foil loss, and low production efficiency, thereby improving the smoothness of hot stamping production, product quality and overall benefits.

[0013] A support mechanism, comprising a support base and a rotary bearing, wherein the support base is rotatably engaged with the guide rod via the rotary bearing.

[0014] As one embodiment, the diameter of the through hole is between 0.1mm and 0.3mm.

[0015] As one embodiment, it also includes a control device, which includes a filter, a pressure regulating valve, a flow meter, and a gas source fine-tuning switch connected in series on the gas pipeline.

[0016] As one embodiment, one end of the gas pipeline of the pneumatic anti-sticking system is connected to the outlet of the compressed air storage tank, and the other end is connected to the inlet of the cavity of the guide rod; the control device is connected in series on the gas pipeline between the compressed air storage tank and the guide rod.

[0017] In one embodiment, the foil feeding component includes a foil feeding frame and a foil feeding roller. The foil feeding frame includes a spool for mounting electroplated aluminum foil. The foil feeding roller is installed downstream of the foil feeding frame, and the axis of the foil feeding roller is parallel to the axis of the spool of the foil feeding frame.

[0018] In one embodiment, the foil taking-up component includes a foil taking-up roller and a foil taking-up wheel, with the foil taking-up roller positioned upstream of the foil taking-up wheel; the axis of the foil taking-up roller is parallel to the axes of the foil feeding roller and the guide rod.

[0019] As one embodiment, the support mechanism further includes a locking device for locking the guide rod; the locking device includes a lock seat fixed on the support base, a lock disc rigidly connected to the end of the guide rod, and a locking pin for cooperating with the lock seat and the lock disc; the edge of the lock disc is provided with evenly distributed lock holes, and the locking pin is adapted to the lock holes and detachably connected to the lock seat.

[0020] As one embodiment, a hot stamping station is provided in the middle of the transmission path of the electroplated aluminum foil. The hot stamping station is located between the downstream of the foil feeding device and the upstream of the foil receiving device. The hot stamping station is provided with a hot stamping heating upper platform and a hot stamping pressing lower platform that cooperate with each other.

[0021] In one embodiment, there are three guide rods: a first guide rod, a second guide rod, and a third guide rod. The first guide rod is located at the inlet end of the hot stamping station, and its axis is parallel to the axis of the foil feeding roller. The second guide rod is located at the outlet end of the hot stamping station. The third guide rod is located at the inlet end of the foil taking-up roller, and its axis is parallel to the axis of the foil taking-up roller.

[0022] A method for preventing sticking during the conveying of electroplated aluminum, characterized by the application of the aforementioned anti-sticking system for electroplated aluminum conveying, comprising the following steps:

[0023] S1. Foil feeding start: Start the foil feeding component of the aluminum foil conveying mechanism to feed the electroplated aluminum foil out from the foil feeding component, and the electroplated aluminum foil enters the aluminum foil transmission path between the foil feeding component and the foil receiving component;

[0024] S2. Conveying and Guiding: The electroplated aluminum foil is conveyed along a preset conveying path, and is guided and supported by a guide rod located in the conveying path. At the same time, gas is injected into the cavity of the guide rod through the gas pipeline of the pneumatic anti-sticking system, so that the gas overflows evenly through the through holes evenly distributed in the circumferential direction of the guide rod, forming an air cushion layer between the guide rod and the electroplated aluminum foil. During the conveying of the electroplated aluminum foil, the guide rod rotates synchronously with the movement direction of the electroplated aluminum foil through the rotating bearing of the support mechanism.

[0025] S3. Foil Collection: The electroplated aluminum foil transported through the transmission path is collected by the foil collection component.

[0026] The present invention achieves the following technical advantages over the prior art:

[0027] 1. Solving the adhesion problem and ensuring transmission stability: The air cushion layer formed by the pneumatic anti-adhesion system (achieved through the coordinated action of the guide rod cavity, through holes, and precise airflow control) establishes a stable physical isolation layer between the guide rod and the electroplated aluminum foil, completely blocking direct contact between the two. This is especially effective in corner areas where adhesion is most likely to occur in traditional equipment; the evenly distributed airflow counteracts the adhesion tendency of the foil due to tension or its own weight. Compared to existing solutions that rely on lubrication or manual peeling, this technology requires no additional chemical media, ensuring stable isolation under different operating conditions and significantly reducing or even eliminating the need for manual intervention due to adhesion.

[0028] 2. Improve foil transport flatness and reduce shape defects: The guide rod's follow-up rotation function (achieved through a rotary bearing) synchronizes with the movement of the electroplated aluminum foil, changing the friction mode from "sliding friction" to "rolling friction" when the foil contacts the guide rod (especially at large angles), significantly reducing the risk of sudden resistance changes. This ensures uniform force and smooth transition of the foil throughout the transport process, effectively preventing wrinkling, stretching deformation, or breakage caused by excessive local friction. It provides a foil base with intact shape and stable tension for the hot stamping process, guaranteeing the edge clarity and surface smoothness of the hot stamping pattern.

[0029] Other technical solutions of this utility model have also achieved the following technical effects:

[0030] 3. Significantly improved ease of operation and safety: Reduced manual intervention: The frequency of manual peeling and adjustment due to adhesion and wrinkling is effectively reduced. Operators do not need to frequently contact high-speed running foil or high-temperature hot stamping parts, reducing the safety risk of scratches and burns, while also reducing labor intensity.

[0031] Flexible locking mechanism switching: Mechanical locking devices such as eccentric handle locks and pneumatic locks can complete the "rotation / locking" state switching in a short time. When threading foil, the guide rod is locked to ensure accurate path. During maintenance, the guide rod is fixed to prevent accidental rotation. The operation process is simple and intuitive, and it is suitable for operators with different skill levels.

[0032] 4. Dual Improvement in Production Efficiency and Material Utilization: Reduced downtime losses. Traditional equipment suffers from prolonged downtime due to adhesion issues; this technology reduces the frequency of such downtimes and extends the effective operating time per shift. The rate of abnormal losses in electroplated aluminum foil (such as adhesion, tearing, wrinkling, and scrapping) is effectively reduced, resulting in annual cost savings and improved operational efficiency. The synergy between the airflow control system (pressure regulating valve, flow meter) and tension control ensures stable output during long periods of continuous production, reducing intermittent downtime caused by parameter fluctuations and improving overall production efficiency.

[0033] 5. Enhance process adaptability and expand application scenarios: This technology can be flexibly adapted to electroplated aluminum foils with different characteristics in the following ways: For easily sticky foils, the airflow intensity can be increased by adjusting the air source switch to enhance the isolation effect; For ultra-thin foils, the foil feeding damping and foil take-up tension can be reduced, and the guide rod can be rotated to reduce friction and avoid tensile breakage.

[0034] 6. Ensure consistent product quality and improve hot stamping pass rate: The uniform isolation of the air cushion layer prevents localized foil adhesion, and the follow-up rotation ensures the positional accuracy of the foil between the hot stamping heating platform and the pressure-replenishing platform. Combined with the flat foil shape, this ensures that temperature and pressure are evenly applied to the contact surface between the foil and the substrate during hot stamping, effectively reducing defects such as blurred patterns, missed stamping, and edge burrs. Practical verification shows that adopting this technology improves the hot stamping pass rate, resulting in a considerable product yield and significantly enhancing product market competitiveness. Through the synergistic design of "physical isolation, follow-up guidance, and precise control," it forms comprehensive advantages in dimensions such as anti-sticking, flatness, operation, efficiency, adaptability, and quality, providing a more reliable and efficient solution for electroplated aluminum foil hot stamping production.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] This embodiment provides an anti-sticking system for electroplated aluminum conveying. Please refer to [link / reference]. Figure 1-4 As shown, the system includes an aluminum foil conveying mechanism, a pneumatic anti-sticking system, and a support mechanism. The aluminum foil conveying mechanism provides the power and path for the transmission of the electroplated aluminum foil 18. The mechanism includes a foil feeding component and a foil collecting component, forming an aluminum foil conveying path between them. The electroplated aluminum foil 18 is output from the foil feeding component, guided by the conveying path, and then collected by the foil collecting component, forming a closed conveying cycle (aluminum foil conveying path). A guide rod 1 is installed in the aluminum foil conveying path. The conveying path passes through multiple guiding positions, especially large-angle corner areas, such as the turning point near the honeycomb panel heating component. These positions are critical areas where the electroplated aluminum foil 18 is most prone to adhesion. The guide rod 1 is installed at these critical guiding positions, especially in corner areas, to support and guide the electroplated aluminum foil 18 during transmission, ensuring it moves along a preset path. The guide rod 1 has through holes 2 evenly distributed along its circumference. A cylindrical cavity extending axially is formed within the guide rod 1, and the cavity communicates with the through holes 2. The through-hole 2 penetrates the surface of the guide rod 1 and directly communicates with the internal cavity, ensuring uniform airflow. After compressed air is introduced into the cavity of the guide rod 1, it forms a uniform and controllable airflow layer (air cushion layer) outward through the surface micropores. The pneumatic anti-sticking system includes a gas pipeline 5, which communicates with the cavity and allows gas to be injected into it. Preferably, one end of the cavity in the guide rod 1 is sealed with an end cap, and the other end serves as an air inlet connected to the gas pipeline 5 of the pneumatic anti-sticking system, forming an airflow channel. The support mechanism includes a support base 3 and a rotary bearing 4. The support base 3 is preferably fixedly mounted on the equipment frame to provide stable support for the guide rod 1; the support base 3 rotates with the guide rod 1 through the rotary bearing 4. When the electroplated aluminum foil 18 needs to rotate naturally or adjust its angle during operation, especially in corner areas, the rotary bearing 4 allows the guide rod 1 to passively follow the electroplated aluminum auxiliary material and rotate synchronously, greatly reducing the relative sliding friction between the foil and the surface of the guide rod 1, effectively preventing wrinkling and tearing.

[0044] Work methods:

[0045] S1. Pre-set pneumatic anti-sticking system:

[0046] Start the pneumatic anti-sticking system and establish a stable airflow environment through the control device to provide the basic conditions for anti-sticking: open the main valve of the compressed air storage tank, and the compressed air enters the control device through the gas pipeline 5; adjust the initial air pressure to the preset range through the pressure regulating valve, and monitor the initial gas flow through the flow meter.

[0047] Based on the characteristics of the electroplated aluminum foil 18, the air source fine-tuning switch is rotated to precisely adjust the airflow pressure and flow rate entering the cavity of the guide rod 1. This ensures that the airflow overflows evenly through the micropores of the guide rod 1, forming an air cushion layer with a thickness of 1-5 μm at the contact surface between the guide rod 1 and the foil. This air cushion layer physically isolates the guide rod 1 from the foil (preventing sticking) while preventing the foil from deviating from the preset conveying path due to excessive buoyancy. The initial parameters are then maintained for a certain period to ensure stable flow meter readings, relatively uniform airflow on the surface of the guide rod 1, and a generally consistent air cushion layer thickness.

[0048] S2, Aluminum foil threading and conveying start-up

[0049] The electroplated aluminum foil 18 is introduced into the conveying path, and the conveying mechanism is started to achieve the initial stable transmission of the foil. The electroplated aluminum foil 18 is led out from the foil feeding component and passes through each guide rod 1 in sequence along the preset conveying path, especially the guide rod 1 in the corner area, to ensure that the foil is parallel and attached to the surface of the guide rod 1, and finally fixed to the foil receiving component.

[0050] Start the electroplated aluminum foil 18 conveying mechanism. The foil feeding component and the foil receiving component operate synchronously, driving the electroplated aluminum foil 18 to be transported along the path. At this time, the guide rod 1 is passively rotated (follow-up rotation) with the foil material movement direction through the rotary bearing 4.

[0051] S3. Dynamic operation and real-time parameter adjustment:

[0052] During continuous conveying, pneumatic parameters and equipment status are dynamically adjusted according to changes in production conditions to ensure stable anti-sticking effect;

[0053] S3.1, Adjustment based on conveyor speed:

[0054] As the conveying speed increases, the relative friction between the foil and guide rod 1 intensifies, increasing the risk of adhesion. At this time, the air pressure is increased by the pressure regulating valve, and the gas flow rate is monitored and increased by the flow meter to thicken the air cushion layer and enhance the isolation effect.

[0055] When the conveying speed decreases, the air pressure and flow rate are adjusted in the opposite direction to prevent the foil from shifting due to excessively thick air cushion layer.

[0056] S3.2, Adjustment based on environmental conditions:

[0057] If the ambient temperature is high, such as exceeding 35℃, the surface coating of the electroplated aluminum foil 18 is prone to softening and the tendency to stick together is enhanced. At this time, keep the air pressure constant and increase the gas flow rate by adjusting the gas source fine-tuning switch. Use the air flow to reduce the local temperature of the guide rod 1 surface and avoid the foil from sticking together due to softening caused by heat.

[0058] S3.3 Adjustment based on adhesion state:

[0059] Slight adhesion, the edge of the foil makes slight contact with guide rod 1 but does not get stuck: increase the air pressure once and increase the flow rate simultaneously, observe for a certain period of time. If the adhesion is resolved, maintain the current parameters; if it is not resolved, repeat the fine adjustment until the adhesion disappears.

[0060] Moderate adhesion, with the foil partially adhering to guide rod 1, resulting in slight wrinkles. First, check if the through hole 2 of guide rod 1 is blocked. If blocked, stop the machine, clean it, and then restart. If not blocked, increase the air pressure and flow rate simultaneously, while observing the flatness of the foil until the wrinkles disappear.

[0061] Severe adhesion, foil jamming or tearing risk, control the conveying mechanism to reduce speed, while significantly increasing air pressure and flow rate, maintain low speed operation for a certain period of time, and gradually restore the original conveying speed after the air cushion layer stabilizes and isolates.

[0062] Step S4, Shutdown and Equipment Reset:

[0063] After production is completed, the conveying speed of the electroplated aluminum foil 18 is gradually reduced to a stop, and the pneumatic anti-sticking system is turned off simultaneously. After the conveying mechanism has completely stopped, the remaining electroplated aluminum foil 18 is detached from the guide rod 1 and recycled to the foil collecting part.

[0064] This invention uses a pneumatic anti-adhesion system to form a precise air cushion layer of 1-5μm between the guide rod 1 and the electroplated aluminum foil 18, achieving contactless isolation between the two at a physical level. Combined with the follow-up rotation function of the guide rod 1 as it moves with the foil, relative friction is greatly reduced, eliminating adhesion in key areas such as corners from the root cause. This effectively avoids foil wrinkling, tearing, and frequent manual intervention caused by adhesion, significantly reducing material loss and safety hazards.

[0065] Meanwhile, the device has the ability to dynamically adjust parameters for conveying speed, ambient temperature and adhesion status, and can adapt to the anti-sticking requirements under different working conditions in real time, ensuring that the air cushion layer always maintains a stable "anti-sticking and non-deviation" effect. This not only improves the smoothness and continuity of the electroplated aluminum foil 18 conveying, but also ensures the consistency of hot stamping quality, providing reliable support for efficient and stable hot stamping production.

[0066] In one embodiment, the aperture of the through hole 2 (micro-hole) of the guide rod 1 is set in the range of 0.1mm-0.3mm, with a preferred aperture of 0.2mm. The selection of this aperture range is based on the synergistic optimization of the stability of the air cushion layer and the anti-sticking effect; the through hole 2 simultaneously meets the core requirements of "uniform airflow overflow" and "controllable air cushion layer thickness"; when the aperture is too large, the electroplated aluminum foil 18 will detach from the preset conveying path due to excessive buoyancy, affecting the transmission stability; when the aperture is too small, the flow resistance of gas in the micro-hole increases sharply, and even if sufficient pressure gas is introduced into the cavity, it is difficult to form a continuous and uniform air cushion layer, making it impossible to achieve effective physical isolation between the guide rod 1 and the foil, and significantly increasing the risk of adhesion.

[0067] The aperture of the through-hole 2 (micro-hole) of the guide rod 1 is set between 0.1mm and 0.3mm, achieving an optimal balance between airflow resistance and output intensity. On one hand, its moderate airflow resistance ensures that compressed air overflows evenly after passing through the cavity of the guide rod 1, avoiding insufficient local airflow due to excessive resistance. On the other hand, its output airflow intensity can stably form an air cushion layer of 1-5μm, which is sufficient to isolate the guide rod 1 from the electroplated aluminum foil 18 (anti-stick) without causing excessive impact on the foil. It is especially suitable for most conventional thicknesses of electroplated aluminum foil 18, maintaining a stable anti-stick effect in the transmission of foils of different materials and widths. At the same time, combined with the uniform distribution design of the guide rod 1 in the circumferential direction, the micro-hole of this aperture ensures that the airflow covers the surface of the guide rod 1 360° without dead angles, further improving the reliability of anti-sticking.

[0068] In one embodiment, a control device is connected in series on the gas pipeline 5 of the dynamic anti-sticking system. The control device includes, in sequence along the gas flow direction, a filter, a pressure regulating valve, a flow meter, and a gas source fine-tuning switch 6.

[0069] As the first stage of airflow treatment before it enters the system, the filter's core function is to remove impurities such as moisture, oil, and dust from the compressed air. This prevents clogging of the micropores and avoids localized airflow interruptions that could lead to adhesion.

[0070] The pressure regulating valve is used to adjust the pressure of the filtered compressed air to a preset working range. Setting the initial pressure through the pressure regulating valve ensures that the airflow has sufficient kinetic energy after entering the cavity of guide rod 1, forming an initial air cushion layer of 1-5μm after overflowing through the micropores. The flow meter monitors the gas flow rate through the pipeline in real time, and its reading provides a quantitative basis for adjusting the airflow parameters. For example, when the speed of the electroplated aluminum foil 18 increases, it is necessary to confirm through the flow meter whether the flow rate increases synchronously with the air pressure to ensure that the thickness of the air cushion layer increases as expected; when the ambient temperature rises, the adjustment effect of the air source fine-tuning switch 6 can also be judged by the change in flow rate to avoid blind operation.

[0071] The air source fine-tuning switch 6 is a precise adjustment component that achieves "micro-correction" of airflow parameters through precise valve opening control. When dealing with slight adhesion or fine-tuning the thickness of the air cushion layer, there is no need to make large adjustments to the pressure regulating valve. Simply rotating the air source fine-tuning switch 6 can achieve a linear change in airflow, which can quickly remove adhesion and avoid foil displacement caused by sudden parameter changes, significantly improving the ease of operation.

[0072] Each guide rod 1 can be equipped with an air pipeline and a separate control device. The series design of the above control devices forms a complete control chain of "filtration and purification → pressure benchmark adjustment → flow quantification monitoring → precise micro-correction", ensuring that the airflow entering the guide rod 1 always meets the requirements of "cleanliness, stability and controllability", providing reliable support for the anti-sticking requirements under different working conditions and realizing the core effect of "anti-sticking and non-displacement" of the air cushion layer.

[0073] In one embodiment, one end of the gas pipeline 5 is connected to the compressed air storage tank 7, and the other end is connected to the air inlet of the cavity of the guide rod 1; preferably, one end of the gas pipeline 5 of the pneumatic anti-sticking system is sealed to the air outlet of the compressed air storage tank 7 through a quick connector, and the other end is sealed to the air inlet of the cavity of the guide rod 1 through a threaded connection or flange structure. All connections are equipped with high-pressure resistant sealing rings to ensure no leakage during airflow transmission.

[0074] In this embodiment, the compressed air storage tank 7 is a cylindrical pressure-resistant container that integrates a pressure sensor and a safety valve. The pressure sensor monitors the pressure inside the tank in real time. When the pressure is lower than a preset threshold, it automatically triggers an external air compressor to replenish the air supply, ensuring that the tank always stores a sufficient amount of compressed air. The safety valve automatically releases pressure when the pressure inside the tank exceeds the limit, ensuring the safe operation of the system. The compressed air storage tank 7 can buffer fluctuations in the air source. When there are instantaneous fluctuations in the output pressure of the external air compressor, the compressed air storage tank 7 can balance the airflow through its own volume, preventing pressure changes from being directly transmitted to the cavity of the guide rod 1, thereby providing a continuous and stable airflow foundation for the stable formation of the air cushion layer.

[0075] The control device is connected in series on the gas pipeline 5 between the air compressor storage tank 7 and the cavity inlet of the guide rod 1, forming a complete airflow path of "storage tank-control device-guide rod cavity". When the compressed air is output from the storage tank, it first passes through the control device to complete filtration, pressure regulation, flow monitoring and fine adjustment, and then enters the cavity of the guide rod 1. Finally, it forms an air cushion layer on the surface of the guide rod 1 through micropores.

[0076] In one embodiment, the foil feeding device serves as the starting point of the electroplated aluminum foil 18 conveying mechanism, used to stably release the electroplated aluminum foil 18 and provide initial guidance. The foil feeding device includes a foil feeding frame 8 and a foil feeding roller 9. The foil feeding frame 8 may be a support structure, and a reel for mounting the electroplated aluminum foil 18 roll is provided on the foil feeding frame 8. Damping adjustment components are provided at both ends of the reel, and the initial tension when the foil roll is released can be precisely controlled by adjusting the damping force. The foil feeding roller 9 is preferably a cylindrical metal shaft, installed downstream of the foil feeding frame 8, and the axis of the foil feeding roller 9 is parallel to the axis of the reel of the foil feeding frame 8. The foil feeding roller 9 guides the electroplated aluminum foil 18 released from the foil roll. After the foil is output from the foil feeding frame 8, it first passes around the surface of the foil feeding roller 9, so that the foil enters the subsequent guide rod 1 in a flat state.

[0077] During operation, the electroplated aluminum foil 18 is released from the foil roll of the foil feeding frame 8, guided and corrected by the foil feeding roller 9, and enters the key conveying path formed by the guide rod 1 with a preset tension. It passes through the anti-sticking guidance treatment of the guide rod 1 in each corner area in sequence, and is finally accurately fed into the hot stamping station between the hot stamping heating upper platform 10 and the hot stamping pressure replenishment lower platform 11. At the hot stamping station, the electroplated aluminum foil 18 completes the hot stamping transfer under the action of heating and pressure, and is then recycled by the foil collecting component.

[0078] In one embodiment, the foil take-up component serves as the end of the electroplated aluminum foil 18 conveying mechanism. The foil take-up component is used to stably recover the electroplated aluminum foil 18 after hot stamping. The foil take-up component includes a take-up roller 12 and a take-up wheel 13, which are arranged sequentially along the foil conveying direction to form a coordinated guiding-rewinding workflow. The take-up wheel 13 is preferably a take-up bob, and the take-up roller 12 is located upstream of the take-up wheel 13, near the downstream of the hot stamping station. The take-up roller 12 is preferably a cylindrical metal shaft, and its axis is parallel to the axes of the foil feeding roller 9 and the guide rod 1. The take-up roller 12 provides final guiding correction for the hot-stamped electroplated aluminum foil 18. After the foil is output from the guide rod 1 at the tail end, it first passes over the surface of the take-up roller 12. Through the support and smooth transition of the shaft, any local wrinkles that may occur during the hot stamping process are eliminated, ensuring that the foil enters the winding stage in a flat state.

[0079] The take-up wheel 13 is preferably an active winding component, including a drive motor and a take-up shaft. The take-up shaft is connected to the drive motor through a reduction mechanism and can rotate at a preset speed to achieve the winding and recycling of the foil. The hot-stamped electroplated aluminum foil 18 is first guided and corrected by the take-up roller 12, and then enters the winding range of the take-up wheel 13, where it is evenly wound onto the take-up shaft under the drive of the drive motor.

[0080] In one embodiment, the support mechanism also integrates a mechanical locking device 14, which is installed at the end connection position between the support base 3 and the guide rod 1. This locking device 14 selectively restricts the rotational freedom of the guide rod 1, enabling flexible switching between "following rotation" and "fixed locking" states. The locking device 14 includes a lock seat fixed to the support base 3, a lock disc rigidly connected to the end of the guide rod 1, and a locking pin for engaging the lock seat and lock disc. The edge of the lock disc is provided with evenly distributed positioning grooves or locking holes. The locking pin is adapted to the positioning grooves or locking holes and detachably connected to the lock seat. When the locking pin is inserted into the positioning groove or locking hole, it can rigidly lock the guide rod 1 to the support base 3 to restrict its rotation. When the locking pin disengages from the positioning groove or locking hole, the guide rod 1 can rotate freely with the rotary bearing 7.

[0081] In this embodiment, the locking device 14 can be in the form of an eccentric handle lock, a pneumatic lock, or a manual latch. Preferably, if it is an eccentric handle lock, it consists of a lock seat fixed on the support base 3, a lock disc rigidly connected to the end of the guide rod 1, and an eccentric handle. The edge of the lock disc is provided with evenly distributed positioning grooves, and the eccentric cam at the end of the handle is adapted to the positioning groove. When the handle is moved to the "locked position", the eccentric cam engages with the positioning groove, and the clamping force generated by the eccentric structure rigidly fixes the guide rod 1 to the support base 3; when moved to the "unlocked position", the cam disengages from the positioning groove, and the guide rod 1 returns to the state of free rotation with the rotary bearing 4. This structure requires little operating force and has no gap after locking.

[0082] If it is a pneumatic lock, it includes a cylinder fixed to the support base 3, a locking pin at the end of the piston rod, and a locking hole disc at the end of the guide rod 1, with the locking holes evenly distributed along the circumference of the locking hole disc. The cylinder's operation is controlled by a solenoid valve: when air is supplied, the piston rod drives the locking pin to insert into the corresponding locking hole on the locking hole disc, achieving rigid locking; when air is released, the locking pin retracts from the locking hole under the action of the return spring, and the guide rod 1 resumes rotation. This structure can be integrated into the equipment control system to achieve automated linkage with processes such as foil threading and maintenance.

[0083] If it is a manual latch, it includes a guide sleeve fixed on the support base 3, a latch that can slide along the axial direction of the guide sleeve, and a positioning hole at the end of the guide rod 1. The end of the latch is provided with a non-slip handle, which locks the guide rod 1 when inserted into the positioning hole and unlocks it when pulled out. The structure is simple and low in cost, making it suitable for scenarios with low automation requirements.

[0084] By locking the guide rod 1 with the locking device 14, during the foil threading process, locking the guide rod 1 prevents it from rotating with the foil, ensuring that the foil is accurately threaded along the preset path. During equipment maintenance, locking the guide rod 1 prevents accidental rotation, ensuring operator safety. In specific processes (such as small-angle turning of wide foil), locking the guide rod 1 to a fixed angle prevents path deviation caused by follow-up rotation. The locking device 14 achieves the dual function of "rotating when needed (flexibly rotating with the foil when unlocked, reducing friction) and stopping when needed (precisely fixed when locked, ensuring stability)," further enhancing the adaptability of the device to complex production scenarios in conjunction with the pneumatic anti-sticking system and the follow-up rotation mechanism. In this way, under conditions where the guide rod 1 does not need to rotate (such as foil threading, maintenance, or specific process requirements), the guide rod 1 can be quickly and firmly locked at the required angle position, ensuring operational stability and achieving flexible operation of "rotating when needed and stopping when needed."

[0085] In one embodiment, a hot stamping station is provided in the middle of the transport path of the electroplated aluminum foil 18. This hot stamping station is the core area for realizing the hot stamping function. It is located between the downstream of the foil feeding device and the upstream of the foil receiving device, forming a complete production process closed loop with the preceding and following guide transport structures. The hot stamping station is equipped with a hot stamping heating upper platform 10 and a hot stamping pressure replenishing lower platform 11 that cooperate with each other.

[0086] The hot stamping heating platform 10 is preferably a flat structure with a built-in heating element. Its working surface faces the surface of the electroplated aluminum foil 18 to be stamped. The temperature can be precisely controlled according to process requirements. It is used to soften the metal plating on the surface of the electroplated aluminum foil 18 through heat conduction, preparing it for subsequent transfer to the substrate surface. The hot stamping pressure lower platform 11 is located directly below the heating upper platform. Its working surface is in contact with the substrate. It can be raised and lowered by a drive mechanism (such as a cylinder or servo motor) to form controllable pressure in conjunction with the heating upper platform. When the electroplated aluminum foil 18 and the substrate enter between the two platforms simultaneously, the pressure lower platform rises, so that the substrate and the softened foil are tightly adhered. Under the combined action of heat and pressure, the transfer of the metal plating is completed, i.e., the hot stamping process.

[0087] During operation, the electroplated aluminum foil 18 output from the foil feeding roller 9 of the foil feeding device first passes through multiple sets of guide rods 1, especially the guide rods 1 in the large-angle corner area near the hot stamping station. Through the guidance and anti-sticking treatment of the guide rods 1, and under the isolation of the air cushion layer of the pneumatic anti-sticking system and the follow-up rotation of the guide rods 1, the foil approaches the hot stamping station in a flat and non-adhesive state. Subsequently, the foil accurately enters the gap between the hot stamping heating upper platform 10 and the hot stamping pressure lower platform 11, and completes the hot stamping under the preset temperature, pressure and dwell time. The hot stamped foil is output from between the two platforms, and after being guided and corrected by the guide rod 1 at the tail end, it finally enters the foil receiving roller 12 and foil receiving wheel 13 of the foil receiving device for recycling.

[0088] The hot stamping station works in synergy with the anti-sticking guide system before and after it. The anti-sticking and flattening guide functions of the guide rod 1 ensure that the electroplated aluminum foil 18 enters the hot stamping area in a stable form, avoiding incomplete or blurry hot stamping patterns caused by foil wrinkles or misalignment. The temperature and pressure parameters of the hot stamping station, in turn, affect the control requirements of the anti-sticking system. When the heating temperature is high, the coating on the surface of the electroplated aluminum foil 18 is more likely to soften and stick. At this time, the airflow parameters need to be appropriately increased through the pneumatic system to further enhance the anti-sticking effect. Both work together to ensure the hot stamping quality and production continuity.

[0089] In one embodiment, the number of guide rods 1 is preferably three, and they correspond to key guiding nodes in the transmission path of the electroplated aluminum foil 18. The three guide rods 1 are the first guide rod 15, the second guide rod 16, and the third guide rod 17. Through the three-stage layout of "inlet pre-guidance, hot stamping correction, and pre-winding calibration", the whole path anti-sticking and flat transmission is achieved.

[0090] The first guide rod 15 is located at the inlet end of the hot stamping station of the hot stamping equipment, near the downstream of the foil feeding device. Its axis is parallel to the axis of the foil feeding roller 9 and is located on the necessary path between the hot stamping heating upper platform 10 and the hot stamping pressure lower platform 11 for the electroplated aluminum foil 18. The first guide rod 15 can "pre-guide and prevent sticking" of the electroplated aluminum foil 18 before it enters the hot stamping area. After the foil is output from the foil feeding device, it first bypasses the surface of the first guide rod 15 and avoids sticking to the guide rod through its pneumatic anti-sticking system (air cushion layer). At the same time, the follow-up rotation of the guide rod 1 eliminates slight wrinkles in the foil transmission, ensuring that it enters the hot stamping station in a flat state, laying the foundation for accurate hot stamping.

[0091] The second guide rod 16 is located at the outlet of the hot stamping station of the hot stamping equipment, near the upstream of the foil collection device. The position of the second guide rod 16 corresponds to that of the first guide rod 15, and its axis is parallel to the working surface of the hot stamping pressure replenishment platform 11. The second guide rod 16 is mainly used for secondary anti-sticking correction of the electroplated aluminum foil 18 after hot stamping. Since the foil may soften due to heat during the hot stamping process, leading to an increased tendency to stick, the second guide rod 16 enhances the stability of the air cushion layer and can appropriately increase the airflow parameters through the control device to prevent the foil from adhering to the surface of the guide rod 1. At the same time, its follow-up rotation function can balance the tension fluctuation of the foil after hot stamping and avoid new wrinkles caused by uneven force.

[0092] The third guide rod 17 is located at the inlet end of the take-up roller 12, i.e., the front end of the take-up device. The third guide rod 17 is situated between the second guide rod 16 and the take-up roller 12, and its axis is parallel to the axis of the take-up roller 12. The third guide rod 17 can perform final calibration before winding. Before entering the winding stage, the foil material passing through the second guide rod 16 needs to have its transmission angle adjusted by the guidance of the third guide rod 17 to match its winding direction with that of the take-up roller 12. At the same time, its anti-sticking system can prevent the foil material from sticking together in the last section of the path before winding, ensuring uniform foil tension and neat winding during winding.

[0093] The first guide rod 15 focuses on "ensuring flatness before hot stamping", the second guide rod 16 emphasizes "strengthening anti-sticking after hot stamping", and the third guide rod 17 is for "path calibration before rewinding". The three cover the key nodes of the transmission path respectively, and each is equipped with an independent pneumatic anti-sticking system and locking device 14, which can be adjusted individually according to the working conditions. This not only avoids the problem of insufficient anti-sticking effect of a single guide rod, but also achieves the integrated function of "anti-sticking-guiding-flatness" through division of labor and cooperation.

[0094] In one embodiment, the guide rod 1 has an operating surface 19 and a transmission surface 20 on both sides. The operating surface 19 is the core area for human-machine interaction of the equipment, integrating a locking device 14 and a status observation module. The guide rod can be quickly controlled to "rotate / lock" by manual switching (such as with an eccentric handle). When locked, the guide rod 1 is fixed to meet the path accuracy requirements during foil threading and debugging. When rotated, the guide rod 1 is released, allowing it to rotate synchronously with the electroplated aluminum foil 18. The transmission surface 20 serves as the power transmission side, supporting the guide rod 1 through a rotary bearing 4 to achieve the follow-up rotation of the guide rod 1 and the electroplated aluminum foil 18. In addition, the transmission surface 20 can integrate an air circuit transfer structure to ensure stable delivery of compressed air to the cavity of the guide rod 1, while preventing aluminum foil debris from intruding, avoiding micropore blockage, and maintaining the uniformity of the air cushion layer.

[0095] Working method of the anti-sticking system for electroplated aluminum conveying:

[0096] S1. System presets and gas path adjustments:

[0097] Open the main valve of the compressed air storage tank. Compressed air enters the control device through the gas pipeline. It passes through the filter to remove moisture, oil and dust to avoid clogging the through hole 2 of the guide rod 3. Then, the pressure regulating valve sets the initial air pressure and the flow meter monitors the flow rate. Finally, the airflow parameters are precisely adjusted by the air source fine-tuning switch.

[0098] Based on the characteristics of the electroplated aluminum foil (such as thickness and coating type), the airflow is uniformly overflowed from the through hole 2 through the axial cavity of the guide rod, forming a 1-5μm air cushion layer on the contact surface between the guide rod and the foil. This air cushion layer can physically isolate the two to prevent adhesion, and will not cause the foil to deviate from the preset path due to excessive buoyancy. The initial parameters are maintained until the flow meter reading stabilizes, and the airflow on the guide rod surface is confirmed to be uniform and the thickness of the air cushion layer is consistent, thus completing the preset.

[0099] S2. Foil threading and conveying start-up:

[0100] The locking devices (such as eccentric handles) on both sides of the operating guide rod 1 lock the guide rod to ensure that the position of the guide rod 1 is fixed during threading; the electroplated aluminum foil 18 is led out from the foil feeding frame 8 of the foil feeding component, and passes through the foil feeding roller 9, the first guide rod 15 (before hot stamping), the hot stamping station entrance, the second guide rod 16 (after hot stamping), the third guide rod 17 (before winding) and the foil taking roller 12 in sequence along the preset path, and is finally fixed to the foil taking component, i.e. the foil taking wheel 13, to ensure that the foil material is parallel and attached to the surface of each guide rod;

[0101] Unlock the locking device and start the aluminum foil conveying mechanism: the foil feeding component provides initial tension through the damping adjustment component, and the drive motor of the foil taking component drives the take-up shaft to rotate synchronously, driving the foil to be transported along the path; at this time, the guide rod 1 is passively rotated (follow-up rotation) with the foil movement direction through the rotating bearing of the support mechanism, converting sliding friction into rolling friction and reducing the risk of sudden resistance changes.

[0102] S3, Dynamic Operation and Parameter Adaptation:

[0103] Based on conveying speed regulation: when the speed increases (friction intensifies), the air pressure is increased by the pressure regulating valve and the flow rate is increased simultaneously to thicken the air cushion layer and enhance isolation; when the speed decreases, the reverse regulation is applied to prevent foil material from shifting.

[0104] Based on environmental and state adjustment: When the ambient temperature exceeds 35℃, keep the air pressure constant and increase the flow rate through the air source fine-tuning switch to reduce adhesion by using airflow to dissipate heat; when slight adhesion occurs, fine-tune the airflow parameters; when moderate adhesion occurs, check whether the micropores are blocked (clean them if blocked) and increase the airflow; when severe adhesion occurs, reduce the speed and significantly increase the airflow, and restore the original speed after stabilization.

[0105] The guide rods work together: the first guide rod 15 pre-guides the foil material before hot stamping to prevent sticking and eliminate wrinkles; the second guide rod 16 strengthens the anti-sticking function after hot stamping and balances tension fluctuations; the third guide rod 17 calibrates the winding angle to ensure neat winding. All three are adapted to their respective working conditions through independent control devices.

[0106] S4. Hot stamping coordination and winding completed:

[0107] The foil material, guided by the first guide rod 15, enters the hot stamping station in a flat state. The hot stamping is completed under the synergistic action of the hot stamping heating upper platform 10 (heating and softening the coating) and the hot stamping pressure lower platform 11 (providing pressure).

[0108] After hot stamping, the foil is corrected by the second guide rod 16 to prevent it from sticking due to softening caused by heat; then the angle is adjusted by the third guide rod 17, and it is guided by the foil take-up roller 12 into the foil take-up wheel 13, where it is evenly wound and recycled to ensure uniform winding tension and no wrinkles.

[0109] It achieves the synergy of "physical isolation of the air cushion layer, drag reduction by follow-up rotation, and dynamic control throughout the entire process", eliminating adhesion in key areas such as corners from the root, reducing manual intervention and material waste, and ensuring the quality of hot stamping and production continuity.
