Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrochemical aluminum foil hot stamping, and in particular to an electrochemical aluminum conveying and anti-sticking system and method thereof. Background Art
[0002] In the hot stamping process, stable foil transport is crucial for ensuring stamping quality and production efficiency. Guide rods, core components in the transport path, are primarily used to support the foil and guide it along a pre-set path. This is especially true when processing specialized substrates like honeycomb panels. Due to the substrate's structural characteristics, the foil must undergo multiple, wide-angle turns to conform to the substrate's hot stamping surface. These corner guide rods must withstand greater foil tension and contact pressure, making them crucial nodes in the transport process.
[0003] However, in the prior art, the guide rods used for large-angle steering are mostly smooth metal rods that make direct physical contact with the anodized aluminum foil. In actual production, because the surface of the anodized aluminum foil is usually coated with a hot-melt coating (such as a metal layer or adhesive layer), it is subject to tension during transmission, resulting in high contact pressure and prolonged friction between the foil and the guide rod in the corner area. This can easily cause the foil to adhere to the guide rod surface due to local temperature increases (frictional heating) or slight dissolution of the coating, resulting in adhesion. This adhesion problem is particularly prominent when processing thin anodized aluminum foil or foil with high adhesion coatings.
[0004] The above-mentioned adhesion problems directly lead to a series of production pain points:
[0005] Frequent manual intervention: To remove adhesion, operators need to frequently stop the machine and manually pull the anodized aluminum foil. This operation is not only cumbersome and labor-intensive, but also poses a safety hazard of scratches and burns due to contact with high-speed transmission components and near high-temperature hot stamping areas. At the same time, manual intervention will directly interrupt the continuous production process and undermine the stability of the transmission path.
[0006] Damaged foil condition: Forcibly pulling the adhered anodized aluminum foil can easily lead to uneven tension distribution, causing local wrinkling, tensile deformation or even breakage. This not only causes foil waste, but also causes quality problems such as blurred, dislocated, and incomplete hot stamping patterns due to foil morphological defects, seriously affecting the product qualification rate.
[0007] Low production efficiency: Adhesion problems require frequent equipment shutdowns, significantly shortening effective operating time. According to actual production data, the equipment's single shutdown time is long and production efficiency is low due to corner guide rod adhesion problems alone.
[0008] Therefore, the existing guide rod structure can no longer meet the stable transmission requirements of anodized aluminum foil in large-angle turning scenarios. There is an urgent need for a technical solution that can effectively prevent the anodized aluminum foil from sticking to the guide rod to solve the above-mentioned problems such as frequent manual intervention, large foil loss, and low production efficiency, thereby improving the smoothness, product quality and comprehensive benefits of hot stamping production. Summary of the Invention

[0022] A method for preventing sticking of electrochemical aluminum during transportation is characterized by applying the above-mentioned electrochemical aluminum transportation and preventing sticking system, comprising the following steps:
[0023] S1. Foil feeding start: The foil feeding component of the aluminum foil conveying mechanism is started to feed the anodized aluminum foil from the foil feeding component. The anodized aluminum foil enters the aluminum foil transmission path between the foil feeding component and the foil receiving component.
[0024] S2. Conveying and guiding: The anodized aluminum foil is conveyed along a preset conveying path, guided and supported by guide rods provided in the conveying path. Simultaneously, gas is injected into the cavity of the guide rods through the gas pipeline of the pneumatic anti-sticking system, causing the gas to evenly overflow through the through holes evenly distributed in the circumferential direction of the guide rods, forming an air cushion layer between the guide rods and the anodized aluminum foil. During the conveying process of the anodized aluminum foil, the guide rods rotate synchronously with the direction of movement of the anodized aluminum foil via the rotary bearing of the support mechanism.
[0025] S3, foil collection: The electrochemical aluminum foil transported through the transmission path is recovered by the foil collection component.
[0026] Compared with the prior art, the present invention has achieved the following technical effects:
[0027] 1. Solve the problem of sticking, ensure the stability of transmission: The air cushion layer formed by the pneumatic anti-sticking system (realized by the guide rod cavity, through hole and precise air flow regulation) establishes a stable physical isolation layer between the guide rod and the aluminum foil, completely blocking direct contact between the two, especially for the corner area of the traditional equipment where sticking is most likely to occur, the uniform overflow of air flow can offset the sticking tendency of the foil due to tension or self-weight. Compared with the existing solution that relies on lubrication or manual peeling, this technology does not require additional chemical media, ensuring stable isolation under different working conditions, greatly reducing or even eliminating the need for manual intervention due to sticking.
[0028] 2. Improve the flatness of foil transmission and reduce form defects: The follow-up rotation function of the guide rod (realized by relying on rotating bearings) can be synchronized with the movement of the aluminum foil, so that the foil changes from "sliding friction" to "rolling friction" when it contacts the guide rod (especially at large-angle corners), significantly reducing the risk of sudden resistance. Ensure that the foil is evenly stressed throughout the transmission, with smooth transitions, effectively preventing wrinkles, stretching or breaking caused by excessive local friction, providing a form complete, tension stable foil basis for the hot stamping link, ensuring the edge definition and surface finish of the hot stamped pattern.
[0029] Other technical solutions of the present application also achieve the following technical effects:
[0030] 3. Significant improvement in operation convenience and safety: Reduce manual intervention: The frequency of manual peeling and adjustment caused by sticking and wrinkling is effectively reduced, operators do not need to frequently touch high-speed running foil or high-temperature hot stamping parts, reducing the risk of being scratched or burned, while reducing labor intensity.
[0031] Flexible switching of locking mechanism: Mechanical locking devices such as eccentric handle locks and pneumatic locks can complete the state switching of "rotation / locking" in a short time, locking the guide rod during foil insertion to ensure accurate path, and fixing the guide rod during maintenance to avoid accidental rotation. The operation process is simple and intuitive, suitable for operators of different skill levels.
[0032] 4. Double improvement of production efficiency and material utilization: Reduce downtime loss, traditional equipment has a long single downtime processing time due to sticking, this technology can reduce the frequency of such downtime, and extend the effective operation time per shift. The rate of abnormal loss of electrochemical aluminum foil (such as sticking and tearing, wrinkling and scrapping) is effectively reduced, the cost is saved annually, and the operation efficiency is improved. The cooperation of the air flow regulation system (pressure regulating valve, flow meter) and the tension control ensures that the equipment maintains stable output in long-term continuous production, reduces intermittent downtime caused by parameter fluctuations, and improves overall output efficiency.
[0033] 5. Enhance process adaptability and expand application scenarios: This technology can be flexibly adapted to different characteristics of anodized aluminum foils through the following methods: For easily sticky foils, the air source fine-tuning switch can be used to increase the airflow intensity and enhance the isolation effect; for ultra-thin foils, the foil feeding damping and foil retraction tension can be reduced, and the guide rod can be rotated to reduce friction and avoid tensile fracture.
[0034] 6. Ensure product quality consistency and improve hot stamping pass rate: The uniform isolation of the air cushion layer prevents local adhesion of the foil, and the follow-up rotation ensures the position accuracy of the foil between the hot stamping heating upper platform and the pressure-replenishing lower platform. Combined with the flat foil shape, the temperature and pressure during hot stamping act evenly on the contact surface between the foil and the substrate, effectively reducing defects such as blurred patterns, missing hot stamping, and edge burrs. Practical verification has shown that the adoption of this technology has improved the hot stamping pass rate, achieved a considerable product yield, and significantly enhanced the product's market competitiveness. Through the collaborative design of "physical isolation, follow-up guidance, and precise control," comprehensive advantages are formed in the dimensions of anti-sticking, flatness, operation, efficiency, adaptability, and quality, providing a more reliable and efficient solution for electrochemical aluminum foil hot stamping production.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] This embodiment provides an electrochemical aluminum conveying anti-sticking system, please refer to Figure 1-4 As shown, it includes an aluminum foil conveying mechanism, a pneumatic anti-sticking system, and a support mechanism. The aluminum foil conveying mechanism provides power and path foundation for the transmission of the electrochemical aluminum foil 18. The aluminum foil conveying mechanism includes a foil feeding component and a foil collecting component. An aluminum foil conveying path is formed between the foil feeding component and the foil collecting component, that is, the electrochemical aluminum foil 18 is output from the foil feeding component, guided by the transmission path, and then recovered by the foil collecting component, forming a closed transmission cycle (aluminum foil conveying path). A guide rod 1 is provided in the aluminum foil conveying path; the transmission path needs to pass through multiple guide positions, especially large-angle corner areas, such as the turning point near the honeycomb panel heating component. These positions are the key areas where the electrochemical aluminum foil 18 is most likely to stick. The guide rod 1 is set at the key guide position of the transmission path, especially the corner area. The guide rod 1 is used to support and guide the electrochemical aluminum foil 18 during transmission to ensure that it moves along the preset path. The guide rod 1 is evenly opened with through holes 2 in the circumferential direction. A cavity extending along the axial direction is opened in the guide rod 1. The cavity has a cylindrical structure and is connected to the through hole 2. In this way, the through hole 2 passes through the surface of the guide rod 1 and is directly connected to the internal cavity, ensuring that the airflow can overflow evenly. After the compressed air is introduced into the cavity of the guide rod 1, a uniform and controllable airflow layer (air cushion layer) is formed outward through the surface micropores. The pneumatic anti-sticking system includes a gas pipeline 5, which is connected to the cavity, and gas can be injected into the cavity through the gas pipeline 5. Preferably, one end of the cavity in the guide rod 1 is sealed by an end cover, and the other end is connected to the gas pipeline 5 of the pneumatic anti-sticking system as an air inlet to form an air flow channel. The support mechanism includes a support seat 3 and a rotating bearing 4. The support seat 3 is preferably fixedly mounted on the equipment frame to provide stable support for the guide rod 1; the support seat 3 rotates with the guide rod 1 through the rotating bearing 4. When the electroplated aluminum foil 18 needs to rotate naturally or adjust the angle during operation, especially in the corner area, the rotating bearing 4 allows the guide rod 1 to passively follow the electroplated aluminum auxiliary material to rotate synchronously, greatly reducing the relative sliding friction between the foil and the surface of the guide rod 1, and effectively preventing wrinkling and tearing.
[0044] Working methods:
[0045] S1. Preset pneumatic anti-sticking system:
[0046] Start the pneumatic anti-sticking system and establish a stable airflow environment through the control device to provide basic conditions for anti-sticking: open the main valve of the air compression 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 anodized aluminum foil 18, the air source fine-tuning switch is rotated to precisely adjust the airflow pressure and flow rate entering the cavity of guide rod 1. After the airflow evenly overflows through the micropores of guide rod 1, a 1-5μm thick air cushion layer is formed on the contact surface between guide rod 1 and the foil. This air cushion layer physically isolates guide rod 1 from the foil (to prevent 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 of time to ensure stable flowmeter readings, relatively uniform airflow on the surface of guide rod 1, and a generally consistent thickness of the air cushion layer.
[0048] S2. Aluminum foil threading and conveying start
[0049] Introduce the anodized aluminum foil 18 into the conveying path, start the conveying mechanism, and realize the initial stable transmission of the foil; lead the anodized aluminum foil 18 out from the foil feeding component, and pass 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 to the surface of the guide rod 1, and finally fixed to the foil collecting component.
[0050] Start the conveying mechanism of the electrochemical aluminum foil 18, and the foil feeding component and the foil collecting component operate synchronously, driving the electrochemical aluminum foil 18 to be transported along the path; at this time, the guide rod 1 passively rotates (follow-rotates) along the movement direction of the foil through the rotating bearing 4.
[0051] S3. Dynamic operation and real-time parameter adjustment:
[0052] During the continuous conveying process, the pneumatic parameters and equipment status are dynamically adjusted according to the changes in production conditions to ensure stable anti-sticking effect;
[0053] S3.1, Based on conveying speed adjustment:
[0054] When the conveying speed increases, the relative friction between the foil and the guide rod 1 intensifies, and the risk of adhesion increases. At this time, the air pressure is increased through the pressure regulating valve, and the gas flow is monitored and increased through 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 reverse to avoid the foil being deflected due to the air cushion being too thick.
[0056] S3.2. Adjustment based on environmental conditions:
[0057] If the ambient temperature is high, such as exceeding 35°C, the surface coating of the electrochemical aluminum foil 18 will easily soften and the tendency to stick will increase. At this time, keep the air pressure unchanged, increase the gas flow rate by fine-tuning the air source switch, and use the air flow fluidity to reduce the local temperature of the guide rod 1 surface to avoid the foil from sticking due to softening due to heat.
[0058] S3.3. Regulation based on adhesion status:
[0059] Slight adhesion, where the edge of the foil slightly contacts the guide rod 1 but is not stuck: Increase the air pressure and flow rate simultaneously, observe for a while, and if the adhesion is relieved, maintain the current parameters; if not, repeat fine-tuning until the adhesion disappears.
[0060] Moderate adhesion: The foil partially adheres to guide rod 1, resulting in slight wrinkles. First, check whether through hole 2 of guide rod 1 is blocked. If so, stop the machine to clean it and restart it. If not, increase the air pressure and flow simultaneously while observing the flatness of the foil until the wrinkles disappear.
[0061] In case of severe adhesion, foil jamming or risk of tearing, control the conveying mechanism to reduce speed, and at the same time significantly increase the air pressure and flow, maintain low-speed operation for a certain period of time, and gradually restore the original conveying speed after the air cushion layer is stably isolated.
[0062] Step S4: Shutdown and equipment reset:
[0063] After production is completed, the conveying speed of the anodized aluminum foil 18 is gradually reduced to a stop, and the pneumatic anti-sticking system is simultaneously turned off; after the conveying mechanism completely stops, the remaining anodized aluminum foil 18 is separated from the guide rod 1 and recovered to the foil collection component.
[0064] The present invention forms a precise air cushion layer of 1-5 μm between the guide rod 1 and the electrochemical aluminum foil 18 through a pneumatic anti-sticking system, thereby achieving contactless isolation between the two from a physical level. Combined with the follow-up rotation function of the guide rod 1 as the foil moves, the relative friction is greatly reduced, and the adhesion phenomenon in key areas such as corners is eliminated from the root, effectively avoiding wrinkling and tearing of the foil due to adhesion and frequent manual intervention, thereby significantly reducing material loss and safety hazards.
[0065] At the same time, the device has the ability to adjust dynamic parameters according to the conveying speed, ambient temperature and adhesion status, and can adapt to the anti-sticking requirements under different working conditions in real time to ensure that the air cushion layer always maintains a stable "anti-sticking and non-drifting" effect. It not only improves the smoothness and continuity of the conveying of the electrochemical aluminum foil 18, but also ensures the consistency of the hot stamping quality, providing reliable support for efficient and stable hot stamping production.
[0066] In one embodiment, the aperture of the through hole 2 (micropore) of the guide rod 1 is set in the range of 0.1mm-0.3mm, wherein the preferred aperture is 0.2mm. The selection of this aperture range is based on the coordinated 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 thickness of the air cushion layer"; when the aperture is too large, the electrochemical aluminum foil 18 will be separated from the preset conveying path due to excessive buoyancy, affecting the transmission stability; when the aperture is too small, the flow resistance of the gas in the micropore increases sharply. Even if the gas with sufficient pressure is introduced into the cavity, it is difficult to form a continuous and uniform air cushion layer, and it is impossible to achieve effective physical isolation between the guide rod 1 and the foil, and the risk of adhesion increases significantly.
[0067] The aperture of the through hole 2 (micropore) of the guide rod 1 is set between 0.1mm and 0.3mm, which can form an optimal balance between airflow resistance and output intensity: on the one hand, its airflow resistance is moderate, which can ensure that the compressed air overflows evenly after passing through the cavity of the guide rod 1, avoiding local airflow shortage due to excessive resistance; on the other hand, the airflow intensity of its output can stably form an air cushion layer of 1-5μm, which is sufficient to isolate the guide rod 1 from the electrochemical aluminum foil 18 (anti-sticking) without causing excessive impact on the foil. It is especially suitable for most electrochemical aluminum foils 18 of conventional thickness and can maintain a stable anti-sticking effect during the transmission of foils of different materials and widths. At the same time, combined with the uniform distribution design of the circumferential direction of the guide rod 1, the micropores of this aperture can ensure that the airflow covers 360° without dead angles along the surface of the guide rod 1, further improving the reliability of anti-sticking.
[0068] In one embodiment, a control device is connected in series to the gas pipeline 5 of the dynamic anti-sticking system. The control device includes a filter, a pressure regulating valve, a flow meter and a gas source fine-tuning switch 6 in sequence along the gas flow direction.
[0069] As the first treatment link for airflow entering 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 micropores and localized airflow interruptions that can cause adhesions.
[0070] The pressure regulating valve is used to adjust the pressure of filtered compressed air to a preset operating range. Setting the initial pressure by the pressure regulating valve ensures that the airflow has sufficient kinetic energy after entering the cavity of the guide rod 1, and forms an initial air cushion layer of 1-5μm after overflowing through the micropores. The flow meter monitors the gas flow 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 electrochemical aluminum foil 18 is increased, 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 thickens as expected; when the ambient temperature rises, the adjustment effect of the air source fine-tuning switch 6 can also be judged by the flow change to avoid blind operation.
[0071] The air source fine adjustment switch 6 is a precise adjustment component, which realizes "micro correction" of the air flow parameter through fine valve opening control. When dealing with slight adhesion or fine adjustment of the air cushion layer thickness, the pressure regulating valve does not need to be adjusted greatly, and linear change of the air flow can be realized only by rotating the air source fine adjustment switch 6, which can quickly remove the adhesion and avoid foil offset caused by parameter mutation, thereby significantly improving the operation convenience.
[0072] Each guide rod 1 can be equipped with a set of air pipes and a set of control devices. The series connection of the control devices forms a complete control chain of "filtration and purification-pressure reference adjustment-flow quantization monitoring-precise micro correction", which ensures that the air flow entering the guide rod 1 always meets the requirements of "clean, stable and controllable", provides reliable support for anti-adhesion requirements in different working conditions, and realizes the core effect of "anti-adhesion without offset" of the air cushion layer.
[0073] In one embodiment, one end of the air pipe 5 is in communication with the air compression storage tank 7, and the other end is in communication with the cavity air inlet of the guide rod 1. Preferably, one end of the air pipe 5 of the pneumatic anti-adhesion system is in sealed communication with the air outlet of the air compression storage tank 7 through a quick connector, and the other end is in sealed butt joint with the cavity air inlet of the guide rod 1 through screw connection or flange structure. High-pressure-resistant sealing rings are arranged at the connection positions to ensure that there is no leakage during air flow transmission.
[0074] In this embodiment, the air compression storage tank 7 is a cylindrical pressure-resistant container, which is internally integrated with a pressure sensor and a safety valve. The pressure sensor monitors the pressure in the tank in real time, and when the pressure is lower than the preset threshold, the external air compressor is automatically triggered to supplement air, so that sufficient compressed air is always stored in the tank. The safety valve automatically releases pressure when the pressure in the tank exceeds the limit, thereby ensuring the safety of system operation. The air compression storage tank 7 can buffer the fluctuation of the air source. When the output pressure of the external air compressor fluctuates instantaneously, the air compression storage tank 7 can balance the air flow through its own volume, thereby avoiding that the pressure mutation is directly transmitted to the cavity of the guide rod 1, and providing a continuous and stable air flow basis for the stability of the air cushion layer.
[0075] The control device is connected in series on the air pipe 5 between the air compression storage tank 7 and the cavity air inlet of the guide rod 1, forming a complete air flow path of "storage tank-control device-guide rod cavity". After the compressed air is output from the storage tank, it is first filtered, pressure-regulated, flow-monitored and fine-adjusted by the control device, and then enters the cavity of the guide rod 1, and finally forms an air cushion layer on the surface of the guide rod 1 through the micro holes.
[0076] In one embodiment, a foil feeder serves as the starting point of the conveying mechanism for the anodized aluminum foil 18, used to stably release the anodized aluminum foil 18 and provide initial guidance. The foil feeder comprises a foil feeder frame 8 and a foil feed roller 9. The foil feeder frame 8 can be a bracket structure. The foil feeder frame 8 is provided with a reel for mounting the anodized aluminum foil 18. Damping adjustment assemblies are provided at both ends of the reel. By adjusting the damping force, the initial tension of the foil roll during release can be precisely controlled. The foil feed roller 9 is preferably a cylindrical metal shaft mounted downstream of the foil feeder frame 8, with the axis of the foil feed roller 9 parallel to the axis of the reel of the foil feeder frame 8. The foil feed roller 9 guides the anodized aluminum foil 18 released from the foil roll. After being discharged from the foil feeder frame 8, the foil first passes over the surface of the foil feed roller 9, allowing the foil to enter the subsequent guide rod 1 in a flat state.
[0077] During operation, after the anodized aluminum foil 18 is released from the foil roll of the foil feeding rack 8, it is 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 guiding treatment of the guide rod 1 in each corner area in turn, and is finally accurately fed into the hot stamping station between the hot stamping heating upper platform 10 and the hot stamping pressing lower platform 11. At the hot stamping station, the anodized aluminum foil 18 completes the hot stamping transfer under the action of heat and pressure, and is then recovered by the foil collecting component.
[0078] In one embodiment, a foil collection component serves as the end of the conveying mechanism for the anodized aluminum foil 18. It is used to stably recycle the anodized aluminum foil 18 that has undergone the hot stamping operation. The foil collection component includes a foil collection roller 12 and a foil collection wheel 13, which are arranged in sequence along the foil conveying direction, forming a coordinated guiding and rewinding process. The foil collection wheel 13 is preferably a foil collection wheel. The foil collection roller 12 is arranged upstream of the foil collection wheel 13 and close to the downstream of the hot stamping station. The foil collection roller 12 is preferably a cylindrical metal shaft, and the axis of the foil collection roller 12 is parallel to the axes of the foil feeding roller 9 and the guide rod 1. The foil collection roller 12 can be used to perform final guide correction on the anodized aluminum foil 18 after hot stamping. After the foil is output from the guide rod 1 at the rear end, it first passes over the surface of the foil collection roller 12. The support and smooth transition of the shaft eliminate local wrinkles that may have occurred in the foil during the hot stamping process, ensuring that it enters the rewinding process in a flat state.
[0079] The foil rewinding wheel 13 is preferably an active rewinding component, comprising a drive motor and a rewinding shaft. The rewinding shaft is connected to the drive motor via a speed reduction mechanism, rotating at a preset speed to rewind the foil. The stamped anodized aluminum foil 18 is first guided and corrected by the foil rewinding roller 12 before entering the rewinding area of the foil rewinding wheel 13 and being evenly wound around the rewinding shaft by the drive motor.
[0080] In one embodiment, the support mechanism further integrates a mechanical locking device 14, which is installed at the connection position between the support seat 3 and the end of the guide rod 1, and is used to selectively limit the rotational freedom of the guide rod 1, thereby achieving flexible switching between the two states of "follow-rotation" and "fixed locking". The locking device 14 includes a lock seat fixed to the support seat 3, a lock disk rigidly connected to the end of the guide rod 1, and a lock pin for matching the lock seat and the lock disk; the edge of the lock disk is provided with evenly distributed positioning grooves or lock holes, and the lock pin is adapted to the positioning grooves or lock holes and is detachably connected to the lock seat. When the lock pin is inserted into the positioning groove or lock hole, it can rigidly lock the guide rod 1 and the support seat 3 to limit their rotation. When the lock pin is disengaged from the positioning groove or lock hole, the guide rod 1 can rotate freely with the rotating bearing 7.
[0081] In this embodiment, the locking device 14 can take 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 base fixed to the support base 3, a lock disk rigidly connected to the end of the guide rod 1, and an eccentric handle. The edge of the lock disk is provided with evenly distributed positioning grooves, and the eccentric cam at the end of the handle fits into the positioning grooves. When the handle is moved to the "locked position," the eccentric cam engages the positioning groove, and the clamping force generated by the eccentric structure rigidly secures the guide rod 1 to the support base 3. When moved to the "unlocked position," the cam disengages the positioning groove, and the guide rod 1 resumes its free rotation state along with the rotary bearing 4. This structure requires little operating force, and there is no play after locking.
[0082] A pneumatic lock consists of a cylinder fixed to the support base 3, a locking pin at the end of the piston rod, and a locking disc at the end of the guide rod 1. The locking holes are evenly distributed along the circumference of the disc. A solenoid valve controls the cylinder's operation: when air is released, the piston rod drives the locking pin into the corresponding locking hole in the locking disc, achieving a rigid lock. When air is released, the locking pin is released from the locking hole by a return spring, and the guide rod 1 resumes rotation. This structure can be integrated into the equipment control system, enabling automated linkage with processes such as foil threading and maintenance.
[0083] If it is a manual latch, it includes a guide sleeve fixed to the support base 3, a latch that can slide axially along the guide sleeve, and a positioning hole at the end of the guide rod 1. The end of the latch is equipped with an anti-slip handle, which locks the guide rod 1 when inserted into the positioning hole and unlocks it when removed. The structure is simple and low-cost, 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 it from rotating unexpectedly, ensuring operator safety. In specific processes (such as small-angle turning of wide-width foil), locking the guide rod 1 to a fixed angle can prevent path deviation caused by follow-up rotation. The locking device 14 achieves the dual functions of "rotating when needed (flexibly rotating with the foil when unlocked, reducing friction) and stopping when needed (precisely fixed when locked, ensuring stability)". In conjunction with the pneumatic anti-sticking system and the follow-up rotation mechanism, the device's adaptability to complex production scenarios is further enhanced. In this way, under working 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 securely 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 anodized aluminum foil 18. This hot stamping station is the core area for hot stamping, located between the downstream of the foil feeding device and the upstream of the foil collecting device, and forms a complete closed loop of the production process with the front and rear guide transmission structures. The hot stamping station is equipped with a hot stamping heating upper platform 10 and a hot stamping pressing lower platform 11 that cooperate with each other:
[0086] The hot stamping heating upper platform 10 is preferably a flat plate structure with a built-in heating element. Its working surface is opposite to the surface of the electrochemical aluminum foil 18 to be stamped. The temperature can be precisely controlled according to the process requirements. It is used to soften the metal coating on the surface of the electrochemical aluminum foil 18 through heat conduction, in preparation for subsequent transfer to the surface of the substrate. The hot stamping pressing 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 driving mechanism (such as a cylinder or servo motor) to form controllable pressure in conjunction with the heating upper platform. When the electrochemical aluminum foil 18 and the substrate enter between the two platforms synchronously, the pressing lower platform rises, so that the substrate is tightly fitted with the heat-softened foil, and the transfer of the metal coating is completed under the synergistic effect of heat and pressure, that is, 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 groups of guide rods 1, especially the guide rods 1 in the large-angle corner area close to the hot stamping station. Through the guidance and anti-sticking treatment of the guide rods 1, 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; then, the foil accurately enters the gap between the hot stamping heating upper platform 10 and the hot stamping pressing lower platform 11, and completes the hot stamping under the preset temperature, pressure and residence time; the stamped foil is output from between the two platforms, and then guided and corrected by the guide rods 1 at the tail end, and finally enters the foil collecting roller 12 and foil collecting wheel 13 of the foil collecting device for recovery.
[0088] The hot stamping station works in synergy with the front and rear anti-sticking guide systems. The anti-sticking and smoothing guiding functions of the guide rod 1 ensure that the anodized aluminum foil 18 enters the hot stamping area in a stable form, avoiding incomplete or blurred hot stamping patterns caused by wrinkles and deviations of the foil. The temperature and pressure parameters of the hot stamping station react on the regulation requirements of the anti-sticking system. When the heating temperature is high, the surface coating of the anodized aluminum foil 18 is more likely to soften and adhere. At this time, the airflow parameters need to be appropriately increased through the pneumatic system to further enhance the anti-sticking effect. The two work together to ensure hot stamping quality and production continuity.
[0089] In one embodiment, the number of guide rods 1 is preferably three, and they correspond to the key guide nodes in the transmission path of the electrochemical aluminum foil 18 respectively. The three guide rods 1 are the first guide rod 15, the second guide rod 16 and the third guide rod 17 respectively. Through the three-stage layout of "import pre-guiding, correction after hot stamping and calibration before winding", full-path anti-sticking and smooth transmission are achieved.
[0090] The first guide rod 15 is located at the entrance of the hot stamping station of the hot stamping equipment, close to 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 path that the anodized aluminum foil 18 must pass through before entering the hot stamping heating upper platform 10 and the hot stamping pressing lower platform 11. The first guide rod 15 can be used to "pre-guide and prevent sticking" of the anodized aluminum foil 18 before entering the hot stamping area. After the foil is output from the foil feeding device, it first passes around the surface of the first guide rod 15 and is prevented from sticking to the guide rod by 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 during transmission, ensuring that it enters the hot stamping station in a flat state, laying the foundation for precise hot stamping.
[0091] Second guide rod 16 is positioned at the exit of the hot stamping station, upstream of the foil collecting device. Its position corresponds to that of first guide rod 15, with its axis parallel to the working surface of hot stamping and pressure-replenishing lower platform 11. Second guide rod 16 primarily provides secondary anti-sticking correction for the anodized aluminum foil 18 after hot stamping. Because the foil may soften due to heat during the hot stamping process, leading to an increased tendency to stick, second guide rod 16 enhances the stability of the air cushion layer and, through a control mechanism, appropriately increases airflow parameters to prevent the foil from adhering to the surface of guide rod 1. Furthermore, its follow-up rotation balances tension fluctuations in the foil after hot stamping, preventing new wrinkles caused by uneven force.
[0092] The third guide rod 17 is located at the inlet of the foil-collecting roller 12, i.e., at the front end of the foil-collecting device. It is positioned between the second guide rod 16 and the foil-collecting roller 12, with its axis parallel to that of the roller 12. The third guide rod 17 facilitates final alignment before rewinding. Before entering the rewinding stage, the foil passing through the second guide rod 16 is guided by the third guide rod 17 to adjust its transmission angle to align with the winding direction of the foil-collecting roller 12. Furthermore, its anti-sticking system prevents the foil from sticking during the final section before rewinding, ensuring uniform tension and neat winding during rewinding.
[0093] The first guide rod 15 focuses on "guaranteeing smoothness before hot stamping", the second guide rod 16 focuses on "anti-sticking enhancement after hot stamping", and the third guide rod 17 is aimed at "path calibration before winding". The three respectively cover the key nodes of the transmission path, and are all equipped with independent pneumatic anti-sticking systems and locking devices 14, which can be adjusted individually according to working conditions. This not only avoids the problem of insufficient anti-sticking effect of a single guide rod, but also realizes the integrated function of "anti-sticking-guiding-smoothing" through division of labor and cooperation.
[0094] In one embodiment, an operating surface 19 and a transmission surface 20 are provided on both sides of the guide rod 1. The operating surface 19 is the core area of human-machine interaction of the equipment, integrating the locking device 14 and the state observation module; the guide rod "rotation / locking" can be quickly controlled by manual switching (such as an eccentric handle). When locked, the guide rod 1 is fixed to meet the path precision requirements during foil threading and debugging; when rotated, the guide rod 1 is released so that it rotates synchronously with the electrochemical aluminum foil 18. The transmission surface 20 serves as the power transmission side, supporting the guide rod 1 through the rotating bearing 4 to achieve the follow-up rotation of the guide rod 1 and the electrochemical aluminum foil 18. In addition, the transmission surface 20 can integrate an air path transfer structure to ensure the stable delivery of compressed air to the cavity of the guide rod 1, while blocking the intrusion of aluminum foil debris, avoiding clogging of micropores, and maintaining the uniformity of the air cushion layer.
[0095] Working method of electrochemical aluminum conveying anti-sticking system:
[0096] S1. System preset and gas circuit debugging:
[0097] Open the main valve of the compressed air storage tank, and the compressed air enters the control device through the gas pipeline, and passes through the filter in turn to remove moisture, oil and dust to prevent clogging of the through hole 2 of the guide rod 3. Then, the initial air pressure is set by the pressure regulating valve, and the flow rate is monitored by the flow meter. Finally, the air flow parameters are accurately adjusted through the air source fine-tuning switch;
[0098] According to the characteristics of the electrochemical aluminum foil (such as thickness and coating type), the air flow is evenly 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 of 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; maintain the initial parameters and run until the flow meter reading is stable, confirm that the air flow on the guide rod surface is uniform and the thickness of the air cushion layer is consistent, and complete the preset.
[0099] S2. Foil threading and conveying start:
[0100] The locking devices (such as eccentric handles) on both sides of the guide rod 1 are operated to lock the guide rod 1 to ensure that the position of the guide rod 1 is fixed during threading; the anodized aluminum foil 18 is drawn out from the foil feeding rack 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 rewinding) and the foil rewinding roller 12 along a preset path, and is finally fixed to the foil rewinding component, that is, the foil rewinding wheel 13, to ensure that the foil is parallel 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 collecting component drives the reel to rotate synchronously, driving the foil to be transported along the path; at this time, the guide rod 1 passively rotates (follow-rotates) in the direction of foil movement through the rotating bearing of the support mechanism, converting sliding friction into rolling friction, reducing the risk of sudden changes in resistance.
[0102] S3. Dynamic operation and parameter adaptation:
[0103] Adjustment based on conveying speed: When the speed increases (friction intensifies), the air pressure is increased through the pressure regulating valve and the flow rate is increased simultaneously, thickening the air cushion layer to enhance isolation; when the speed decreases, the reverse adjustment is made to avoid foil deviation;
[0104] Adjust based on the environment and status: When the ambient temperature exceeds 35°C, maintain the air pressure unchanged, increase the flow rate by adjusting the air source fine-tuning switch, and use airflow to dissipate heat and reduce adhesion; fine-tune the airflow parameters when slight adhesion occurs; check whether the micropores are blocked (clean them if blocked) and increase the airflow when moderate adhesion occurs; reduce the speed and significantly increase the airflow when severe adhesion occurs, and restore the original speed after stabilization;
[0105] The guide rods work together: the first guide rod 15 pre-guides the foil before hot stamping to prevent sticking and eliminate wrinkles; the second guide rod 16 strengthens the anti-sticking 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 completion:
[0107] The foil guided by the first guide rod 15 enters the hot stamping station in a flat state, and the hot stamping is completed under the coordinated action of the hot stamping heating upper platform 10 (heating and softening the coating) and the hot stamping pressing lower platform 11 (providing pressure);
[0108] After hot stamping, the foil is corrected by the second guide rod 16 to avoid adhesion due to softening due to heat; then the angle is adjusted by the third guide rod 17, and it is guided by the foil collection roller 12 and enters the foil collection wheel 13, where it is evenly wound and recycled to ensure uniform winding tension and no wrinkles.
[0109] It realizes the synergy of "physical isolation of air cushion layer, follow-up rotation resistance reduction and dynamic regulation of the whole process", eliminates adhesion in key areas such as corners from the root, reduces manual intervention and material loss, and ensures hot stamping quality and production continuity.
