[0002] The metal film hot-dip coating device is an efficient and precise device specially used to form uniform and high-quality metal films on substrates through hot-dip coating technology. It uses a vacuum system to create a high vacuum environment, heats the coating material to an evaporation state through a heating system, and then controls these metal atoms or molecules to be uniformly deposited on the substrate, thereby forming a metal film with specific functions and properties.

[0003] For small enterprises, the existing metal film hot-dip coating devices are expensive for professional equipment for hot-dip coating of metal films on a single surface of a longer material. The high equipment cost directly leads to high maintenance cost. The equipment maintenance cost mainly includes repair cost, maintenance cost and replacement cost.

[0052] Furthermore, when the first positive and negative threaded rod 304 is rotated, due to the design of the positive and negative threaded rods, the two slides 307 will move toward the center or both sides respectively, and the slide 307 slides in the first guide groove 308 through the first guide rail 309, and the clamping plate 3010 on the slide 307 moves accordingly, thereby clamping or releasing the inner support mechanism 6 of different sizes, and the spline sleeve 3012 inside the clamping plate 3010 is slidably sleeved on the outside of the spline shaft 302, so that the two clamping plates 3010 can move along the spline shaft 302, and the first synchronous wheel 3020 fixedly sleeved on the outside of the spline shaft 302 is passed through It is driven to rotate by the driving mechanism 2. When the spline shaft 302 rotates, the two spline sleeves 3012 will be driven to rotate at the same time, and the two lower transmission wheels 3013 will rotate accordingly. The two first transmission belts 3017 respectively drive the two upper transmission wheels 3016 to rotate, thereby driving the rotation of the docking column 3015 and the swivel seat 3018, thereby realizing the rotation of the internal support mechanism 6, the winding drum 11 and the coil 12 to be processed. Through the design of the first positive and negative screw rods 304 and the slide seat 307, the clamping mechanism can achieve stable clamping of coils 12 to be processed of different sizes, ensuring stability during the coating process.

[0053] In the preferred technical solution of this embodiment, please refer to Figure 9-10The four clamping plates 3010 slide in the two movable grooves 109 respectively.

The inner ring of the second support bearing 405 is fixed A connecting rod 406 is provided in the sleeve, and a transmission rod 407 is rotatably provided in the isolation sleeve 404 of the connecting rod 406, and the transmission rod 407 and the connecting rod 406 are fixedly connected, and a plurality of transmission permanent magnets 408 are fixedly embedded in a ring-arranged manner on the outer side of the transmission rod 407, and a plurality of transmission permanent magnets 408 are fixedly connected to a fixing ring 409 at the side of the sealing tube 401 away from the fixing plate 402, and an auxiliary bearing 4010 is fixedly provided at the center of the fixing ring 409, and a driving rod 4011 is fixedly provided on the inner ring of the auxiliary bearing 4010, and a driving sleeve 4012 is rotatably provided in the sealing tube 401 outside the isolation sleeve 404, and the driving sleeve 4012 and the driving rod 4011 are fixedly connected, and a plurality of driving permanent magnets 4013 are fixedly embedded in a ring-arranged manner inside the driving sleeve 4012, and an operating knob 4014 is fixedly connected to the side of the driving rod 4011 away from the driving sleeve 4012.

[0054] Furthermore, when the first vacuum stepper motor 202 is working, the first drive belt 205 and the second drive belt 206 are driven to rotate through the first drive wheel 203 and the second drive wheel 204, thereby driving the two spline shafts 302 to rotate, and the transmission rod 407 is connected to the fixed plate 402 through the connecting rod 406, and the transmission rod 407 rotates inside the isolation sleeve 404, realizing the transmission of power, and the multiple transmission permanent magnets 408 arranged in a ring outside the transmission rod 407 constitute the magnetic field of the transmission part, and the multiple driving permanent magnets 4013 arranged in a ring inside the driving sleeve 4012 constitute the magnetic field of the driving part. When the operating knob 4014 is rotated, it drives the driving rod 4011 and The driving sleeve 4012 rotates together. At this time, the magnetic field generated by the driving permanent magnet 4013 interacts with the magnetic field of the transmission permanent magnet 408 to form a magnetic coupling system. Under the action of magnetic coupling, the driving permanent magnet 4013 transmits the rotational torque to the transmission permanent magnet 408 through the magnetic field, thereby driving the transmission rod 407 to rotate. Since the transmission rod 407 is fixedly connected to the connecting rod 406, and the connecting rod 406 is fixedly connected to the first forward and reverse screw rod 304, the rotation of the transmission rod 407 will drive the first forward and reverse screw rod 304 to rotate, and power transmission is achieved through magnetic coupling without physical contact, thereby reducing friction and wear, and improving transmission efficiency and equipment life.

[0055] In the preferred technical solution of this embodiment, please refer to Fig.11 , the two connecting rods 406 are fixedly connected to one end of the two first positive and negative threaded rods 304 at one side away from the two transmission rods 407, and the first tensioning mechanism 5 includes four bottom blocks 501, two of which are fixedly connected to one side of the upper end of the cover plate 105, and the other two bottom blocks 501 are fixedly connected to the other side of the upper end of the cover plate 105, and the upper ends of the four bottom blocks 501 are fixedly connected to two first sleeves 502, and the inner centers of the two first sleeves 502 are fixedly sleeved with first bearings 503 at both ends, and the inner rings of the two first bearings 503 on one side and the two first bearings 503 on the other side are fixedly sleeved with two first threaded rods 504, and the two first sleeves 502 are fixedly sleeved with two first threaded rods 504.

[0056] Furthermore, by rotating the wheel 509 at the upper end of one of the first screw rods 504, the screw rod will rotate and drive the first slider 506 threadedly connected thereto to move up and down. Since the two first screw rods 504 achieve synchronous rotation through the second synchronous wheel 5010 and the second transmission belt 5011, the two first sliders 506 will move up or down at the same time, thereby adjusting the height of the tensioning roller 508.

When the second forward and reverse screw rod 603 needs to be rotated, pull the pull plate 6012 to separate the annular toothed disc 607 and the movable toothed disc 6013, and rotate the guide plate 6015. When the guide plate 6015 rotates, it will simultaneously drive the docking round rod 6011 and the second forward and reverse screw rod 603 to rotate.

[0060] Furthermore, the coating system composed of the evaporation coating mechanism 7 and the isolation mechanism 8 mainly works on the resistive heating evaporation process driven by low voltage and high current. The low voltage and high current are introduced into the electrode sleeve 704 of the evaporation coating mechanism 7 through two cables 15. This low voltage and high current ensures that sufficient heat can be generated during the heating process, while reducing the damage to the equipment that may be caused by excessive current. The current flows from the electrode sleeve 704 through the first electrode cap 707 and the second electrode cap 708 into the tungsten boat 709 and the tungsten wire 7010. Since the tungsten boat 709 and the tungsten wire 7010 both have a certain resistance, heat is generated when the current passes through, realizing resistive heating. The high temperature thermal radiation generated by the tungsten wire 7010 first melts the metal target material 9017. As the temperature continues to rise, the melted metal target material 9017 drips onto the tungsten boat 709 and continues to evaporate under heat. The material atoms or molecules form a coating cloud, which is then deposited on the surface of the material wound on the reel 11 to form a uniform coating layer. The isolation mechanism 8 supports and stabilizes the evaporation coating mechanism 7 through the main support plate 801 and the side support plate 803. At the same time, the design of the top plate 805 and the material pass slit 809 provides a specific travel path for the coating material to ensure the smooth progress of the coating process. The guide roller 808 is installed between the ear pieces 807 to guide the material wound on the reel 11 to enter and leave the coating area to ensure that the material maintains the correct position and tension during the coating process. Through the low-voltage and high-current resistance heating method, the metal target material 9017 can be ensured to melt and evaporate evenly and quickly in the evaporation coating mechanism 7, thereby forming a uniform coating layer on the reel 11. The use of low-voltage and high-current not only ensures heating efficiency, but also helps to reduce energy consumption and improve the economic benefits of production.

[0062] Furthermore, when the second vacuum stepper motor 907 is started, it drives the rotating column 908 to rotate, and the rotation of the rotating column 908 drives the winding disk 9010 to rotate. This winding disk 9010 begins to collect and pull the molybdenum wire 9016. Driven by the rotating column 908, the molybdenum wire 9016 is guided by two lower guide wheels 9021 and two upper guide wheels 9023, and constrained by the second wire holes 9019 on the two second wire passing plates 9018, thereby ensuring the stability of the molybdenum wire 9016 during the feeding process and the accuracy of the path.

A second sleeve 1003 is fixedly connected to the upper end of the mounting seat 1001, and a second screw rod 1004 is rotatably connected to the inner bottom wall of the second sleeve 1003. The upper end of the second screw rod 1004 is rotatably connected to the upper part of the inner part of the second sleeve 1003, and the upper end of the second screw rod 1004 penetrates The second sleeve 1003 is passed through the inner top wall to the upper end of the second sleeve 1003, the upper end of the second screw rod 1004 is fixedly connected with the second butterfly knob 1005, the two inner walls of the second sleeve 1003 are provided with second slide grooves 1006, the outer side of the second screw rod 1004 is threadedly sleeved with a second slider 1007, the second slider 1007 is slidably sleeved inside the second sleeve 1003, and the second slider 1007 is fixedly connected with second slide rails 1008 at the centers of both sides, the two second slide rails 1008 are respectively slidably sleeved inside the two second slide grooves 1006, and one side of the second slider 1007 is rotatably connected with a ceramic tensioning wheel 1009.

[0064] Furthermore, the second tensioning mechanism 10 is mainly used to tension the molybdenum wire 9016 to ensure that the molybdenum wire 9016 maintains appropriate tension during the operation of the feeding mechanism 9 to avoid loosening or breaking. The second butterfly knob 1005 is rotated, and the second butterfly knob 1005 drives the second screw rod 1004 to rotate. The rotation of the second screw rod 1004 will be converted into the up and down movement of the second slider 1007 in the second sleeve 1003. The second slide rails 1008 on both sides of the second slider 1007 slide in the second slide groove 1006 to ensure the stability and linearity of the slider during movement. As the second slider 1007 moves up and down, the ceramic tensioning wheel 1009 will also move up and down accordingly. When the tensioning wheel moves downward, it will compress the passing molybdenum wire 9016, thereby increasing the tension of the molybdenum wire 9016. Conversely, when the tensioning wheel moves upward, the tension of the molybdenum wire 9016 will decrease.
