Description

Technical Field

[0001] This utility model relates to an oven for processing composite copper foil, belonging to the field of composite copper foil processing technology. Background Technology

[0002] As a key electronic material, composite copper foil inevitably retains moisture and trace amounts of electrolyte on its surface after water-plating anti-oxidation treatment. These two residual substances can cause multiple performance problems, directly affecting product quality and service life. Residual moisture dilutes or dissolves the antioxidant on the copper foil surface, resulting in defects in the formed antioxidant film. This film cannot effectively prevent the copper foil from being oxidized and corroded by air for a long time, thus shortening the product's service life. When moisture combines with residual trace amounts of electrolyte, it forms an electrochemical corrosion environment on the copper foil surface, accelerating localized rusting and blackening of the copper foil, severely affecting the product's appearance and performance. Therefore, drying after water plating is one of the core processes in composite copper foil processing.

[0003] Existing drying equipment has significant technical shortcomings in practical applications:

[0004] When composite copper foil is dried in an oven, the baking time is short, and the film surface can often only be tightened and straightened by increasing the speed difference during winding. However, it is impossible to adjust the tension of the composite copper foil in real time. If the tension is too high, the film material may undergo plastic deformation, leading to defects such as wrinkles in the future.

[0005] To monitor the drying status of copper foil in the oven in real time, existing equipment usually has a viewing glass on the door. However, the high temperature inside the oven and the room temperature outside the glass create a significant temperature difference. In addition, after the residual moisture on the surface of the copper foil evaporates and cools down, it will condense into tiny water droplets on the inside of the glass, forming water mist that completely obscures the view and makes it impossible to detect abnormalities in the drying of the copper foil in time. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an oven for processing composite copper foil.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] An oven for processing composite copper foil includes: an oven, with inlet and outlet slots for conveying composite copper foil on both sides of the oven; three drive rollers parallel to the inlet and outlet slots are rotatably mounted on one end of the oven; a tensioning mechanism is provided below the drive rollers; a heating mechanism is provided inside the oven; a door is rotatably mounted on one end of the oven; heat-resistant glass is installed in the middle of the door; and a wiping mechanism for wiping the inner wall of the heat-resistant glass is provided on the door.

[0009] Preferably, the tensioning mechanism includes two vertical boxes, which are installed on the inner wall of one end of the oven. A threaded rod extending downwards and outwards is rotatably connected between the upper and lower ends of each vertical box. Limiting grooves are provided on the side walls of the two vertical boxes. Threaded blocks are provided on the outer wall of the threaded rods through threads. The two sides of the threaded blocks are arranged in the limiting grooves. Tensioning rollers are rotatably installed on the side of the threaded blocks facing the oven door. The two tensioning rollers are respectively located below the middle of two adjacent transmission rollers. A transmission assembly is provided at the bottom of the threaded rods.

[0010] Preferably, the transmission assembly includes a transmission rod, which is rotatably mounted between the two sides of the oven. The bottom of the threaded rod is equipped with a main bevel gear, and the outer side wall of the transmission rod is equipped with a secondary bevel gear that meshes with the main bevel gear.

[0011] Preferably, the heating mechanism includes two air boxes, which are respectively installed on the top inner wall and bottom inner wall of the oven. Multiple air nozzles are installed on the air boxes, and a connecting pipe is installed at one end of each air box. A hot air blower is installed on the top of the oven, and the air outlet of the hot air blower is connected to a main pipe through a U-shaped pipe. The connecting pipe and the main pipe are connected in communication.

[0012] Preferably, two infrared heating tubes are installed on the upper and lower sides of the inner wall of one end of the oven.

[0013] Preferably, the wiping mechanism includes a horizontal groove, which is formed above the inner wall of the door. A lead screw is rotatably installed in the horizontal groove. A lead screw seat is provided on the outer wall of the lead screw through a thread. The lead screw seat moves along the length of the lead screw. A heat-resistant fiber wiping block is provided at one end of the lead screw seat through an adjustment component. A protective component is provided on the door to protect the heat-resistant fiber wiping block.

[0014] Preferably, the adjustment assembly includes a U-shaped plate, which is fixedly installed on the side of the wire seat away from the door. A screw is rotatably installed between the U-shaped plate and the wire seat. The outer wall of the screw is threaded with a mounting plate, which moves along the extension direction of the screw. The heat-resistant fiber wiping block is installed at one end of the mounting plate.

[0015] Preferably, one end of the mounting plate and the heat-resistant fiber wiping block are detachably mounted via Velcro.

[0016] Preferably, a handle is installed at one end of the screw.

[0017] Preferably, the protective component includes an electric cylinder, which is installed on the outside of the box door. A long groove is formed on one side of the inner wall of the box door, and the output end of the electric cylinder passes through the long groove and is fitted with a protective box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The transmission assembly, through the transmission rod and the meshing of the main and auxiliary bevel gears, works in conjunction with the tensioning mechanism to achieve synchronous lifting and lowering adjustment of the two tensioning rollers. This ensures uniform tension of the copper foil, reduces plastic deformation, effectively prevents wrinkles during winding, guarantees processing accuracy, and alters the trajectory of the film material within the oven, increasing the baking time of the composite copper foil and improving efficiency. The mechanical adjustment structure using a threaded rod and transmission assembly replaces the traditional direct drive method of the electric cylinder. The servo motor on one side of the transmission rod is installed on the outside of the oven, preventing the drive components from being exposed to high temperatures for extended periods. This completely solves the problem of heat aging in electric cylinders and significantly improves the stability and service life of the tensioning mechanism.

[0020] 2. The wiping mechanism on the cabinet door quickly removes water vapor from the inside of the heat-resistant glass. A lead screw drives the heat-resistant fiber wiping block to move laterally, efficiently wiping the inner glass wall and ensuring a clear view. This allows operators to monitor the copper foil drying process in real time and promptly identify and address any abnormalities. The adjustment component, driven by a screw, moves the mounting plate, flexibly adjusting the fit between the heat-resistant fiber wiping block and the glass. Even after the wiping block wears down, adjustments can maintain a good wiping effect. The removable Velcro design facilitates wiping block replacement, reducing maintenance costs. When the wiping block is not in use, an electric cylinder drives a protective box to enclose it, preventing dust and impurities from accumulating on the wiping block, extending its lifespan, and ensuring stable wiping results.

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1 This utility model provides a technical solution:

[0030] An oven for processing composite copper foil includes: an oven 1, with inlet and outlet slots 2 for conveying composite copper foil on both sides of the oven 1, a PLC controller 3 on one side of the oven 1, three drive rollers 4 parallel to the inlet and outlet slots 2 rotatably mounted on one end of the oven 1, a tensioning mechanism 5 below the drive rollers 4, a heating mechanism 6 inside the oven 1, a door 7 rotatably mounted on one end of the oven 1, heat-resistant glass 8 installed in the middle of the door 7, and a wiping mechanism 9 for wiping the inner wall of the heat-resistant glass 8 on the door 7.

[0031] Furthermore, the PLC controller 3 can be the Delta DVP-EX3 series.

[0032] Please see Figure 2In this embodiment: the tensioning mechanism 5 includes two vertical boxes 501, which are installed on the inner wall of one end of the oven 1. A threaded rod 502 extending downwards and outwards from both the upper and lower ends of each vertical box 501 is rotatably connected to it. First limiting grooves are provided on the side walls of the two vertical boxes 501. Threaded blocks 503 are threaded onto the outer wall of the threaded rod 502, with both sides of the threaded blocks 503 positioned within the limiting grooves. Tensioning rollers 504 are rotatably mounted on the side of the threaded blocks 503 facing the oven door 7. The two tensioning rollers 504 are located below the midpoint between two adjacent transmission rollers 4. A transmission assembly 505 is provided at the bottom of the threaded rod 502. By moving the tensioning rollers 504 of the tensioning mechanism 5 up and down, the two tensioning rollers can be synchronously adjusted, ensuring uniform copper foil tension, reducing plastic deformation, and effectively preventing wrinkles.

[0033] Furthermore, the height of the vertical box 501 is adapted to the threaded rod 502, which can limit the maximum lifting stroke of the threaded block 503 and prevent the tension roller 504 from colliding with the transmission roller 4 due to over-adjustment, thus protecting the equipment components. The threaded block 503 and the first limiting groove on the inner wall of the vertical box 501 adopt a clearance fit, and a high-temperature resistant graphite slider is embedded at the fit point, which reduces the frictional resistance when the threaded block 503 is lifted and lowered, and also avoids wear caused by direct friction between metals, thus extending the service life of the components. The roller surface of the tension roller 504 is covered with a high-temperature resistant rubber layer, and the surface of the rubber layer is provided with anti-slip texture, which can increase the friction with the copper foil and prevent the copper foil from slipping or deviating during the tensioning and conveying process. At the same time, the rubber material has a certain degree of elasticity, which can buffer the impact of the tension force on the copper foil and prevent the copper foil from being torn or plastically deformed due to excessive tension.

[0034] Please see Figure 2 In this embodiment: the transmission assembly 505 includes a transmission rod 5051, which is rotatably mounted between the two sides of the oven 1. The bottom of the threaded rod 502 is equipped with a main bevel tooth 5052, and the outer side wall of the transmission rod 5051 is equipped with a secondary bevel tooth 5053 that meshes with the main bevel tooth 5052.

[0035] Furthermore, one end of the transmission rod 5051 extends to the outside of the oven 1 and is equipped with a stepper motor. The height of the tension roller 504 can be automatically adjusted by the PLC controller 3. The main bevel gear 5052 and the auxiliary bevel gear 5053 are both made of high-strength alloy steel to ensure the load-bearing capacity during meshing and transmission, and to avoid wear or breakage of the tooth surface.

[0036] Please see Figure 3In this embodiment: the heating mechanism 6 includes two air boxes 601, which are respectively installed on the top inner wall and bottom inner wall of the oven 1. Multiple air nozzles 602 are installed on the air boxes 601. A connecting pipe 603 is installed at one end of the air box 601. A hot air blower 604 is installed on the top of the oven 1. The air outlet of the hot air blower 604 is connected to the main pipe 605 through a U-shaped pipe. The connecting pipe 603 and the main pipe 605 are connected.

[0037] Furthermore, the air chamber 601 is equipped with a baffle plate to ensure even distribution of hot air within the chamber, preventing uneven hot air jetting caused by excessive or insufficient local air pressure. The air nozzles 602 are angled at 45° towards the copper foil conveying path, with equal spacing between adjacent nozzles. This ensures that the hot air directly acts on the copper foil surface while preventing wrinkles caused by vertical impact, and simultaneously achieves complete coverage of both the upper and lower surfaces of the copper foil. The outer wall of the pipe is wrapped with high-temperature resistant insulation cotton to reduce heat loss during transport and ensure stable hot air temperature entering the air chamber 601. A temperature sensor and flow regulating valve are installed on the main pipe 605. The temperature sensor monitors the hot air temperature in real time and feeds the data back to the PLC controller 3. If the temperature deviates from the preset value, the PLC controller 3 automatically adjusts the heating power of the hot air blower 604 or the opening of the flow regulating valve to achieve precise control of the hot air temperature.

[0038] Please see Figure 3 In this embodiment, two infrared heating tubes 606 are installed on the upper and lower sides of the inner wall of one end of the oven 1.

[0039] Furthermore, the infrared heating tube 606 is a carbon fiber infrared heating tube encapsulated in a quartz glass tube, with a wavelength range of 2-5μm, matching the absorption wavelength of moisture on the copper foil surface. An arc-shaped reflector, made of polished aluminum, is provided on the outside of the heating tube to reflect infrared radiation onto the copper foil surface, reducing heat loss to the inner wall of the oven 1 and improving energy utilization. The infrared heating tube 606 is electrically connected to the PLC controller 3.

[0040] Please see Figure 4 In this embodiment: the wiping mechanism 9 includes a horizontal groove 901, which is opened above the inner wall of the door 7. A lead screw 902 is rotatably installed in the horizontal groove 901. A lead screw seat 903 is provided on the outer side wall of the lead screw 902 through a thread. The lead screw seat 903 moves along the length direction of the lead screw 902. A heat-resistant fiber wiping block 905 is provided at one end of the lead screw seat 903 through an adjusting component 904. A protective component 906 is provided on the door 7 to protect the heat-resistant fiber wiping block 905.

[0041] Furthermore, a guide rod is provided inside the transverse groove 901 parallel to the lead screw 902. The guide rod passes through the lead seat 903 and slides with it, limiting the rotational tendency of the lead seat 903 with the lead screw 902. This ensures that the lead seat 903 drives the heat-resistant fiber wiping block 905 to move smoothly in a straight line, avoiding deviation of the wiping trajectory and incomplete glass wiping. The lead screw 902 adopts a trapezoidal thread design, which features high transmission efficiency and good self-locking performance. This ensures that the lead seat 903 moves quickly for efficient wiping, and also allows the lead seat 903 to remain stably in the designated position when the drive stops, preventing the wiping block from shifting due to vibration. One end of the lead screw 902 is connected to a servo motor, which is installed at one end of the door 7. The servo motor reduces its speed and increases its torque through a reducer, ensuring that the lead screw 902 can operate smoothly and without jamming even when encountering thick water vapor on the glass surface when driving the lead seat 903 and the wiping block. The servo motor is linked with the PLC controller 3.

[0042] Please see Figure 5 In this embodiment: the adjustment component 904 includes a U-shaped plate 9041, which is fixedly installed on the side of the screw seat 903 away from the door 7. A screw 9042 is rotatably installed between the U-shaped plate 9041 and the screw seat 903. An installation plate 9043 is provided on the outer side wall of the screw 9042 by means of threads. The installation plate 9043 moves along the extension direction of the screw 9042. A heat-resistant fiber wiping block 905 is installed at one end of the installation plate 9043.

[0043] Furthermore, a limiting rod is fixedly installed between the U-shaped plate 9041 and the screw seat 903. The limiting rod is slidably connected to the mounting plate 9043, which serves as a limiting function.

[0044] Please see Figure 5 In this embodiment: one end of the mounting plate 9043 and the heat-resistant fiber wiping block 905 are detachably mounted via Velcro.

[0045] Furthermore, the Velcro used to connect the mounting plate 9043 and the heat-resistant fiber wiping block 905 has hook and loop sides made of high-temperature resistant nylon, which can withstand the high temperatures inside the oven and avoid problems such as adhesion failure and material aging caused by long-term exposure to high temperatures. The adhesive area of ​​the Velcro is the same as the back area of ​​the heat-resistant fiber wiping block 905.

[0046] Please see Figure 5 In this embodiment: a handle 9044 is installed at one end of the screw 9042.

[0047] Furthermore, the handle 9044 is made of high-temperature resistant ABS plastic injection molding, and its surface has a textured anti-slip pattern, which can increase the friction between the operator's hand and the handle to prevent slippage during adjustment, and also improve the grip comfort.

[0048] Please see Figure 4 In this embodiment: the protective component 906 includes an electric cylinder 9061, which is installed on the outside of the box door 7. A long groove 9062 is provided on one side of the inner wall of the box door 7. The output end of the electric cylinder 9061 passes through the long groove 9062 and is connected to the protective box 9063.

[0049] Furthermore, the electric cylinder 9061 is a miniature high-temperature resistant electric cylinder with an operating temperature range of -20℃ to 80℃. Installed on the outside of the door 7 (away from the high-temperature area inside the oven), it effectively avoids the impact of high temperatures on the internal motor and lead screw, extending the service life of the electric cylinder. The output shaft of the electric cylinder 9061 is connected to the protective box 9063 via a flange, with a sealing gasket at the flange to prevent hot air from escaping from the connection gap. The inner wall of the long slot 9062 has a guide groove, and the two sides of the protective box 9063 have protrusions that match the guide groove, ensuring that the protective box rises and falls smoothly along the long slot under the drive of the electric cylinder, avoiding jamming or deviation. The edge of the slot of the long slot 9062 is equipped with a high-temperature resistant sealing strip, which fits tightly against the surface of the protective box when it descends to the closed state. The protective box 9063 has a soft, high-temperature resistant sponge pad inside. The sponge pad fits against the inner wall of the protective box. When the protective box wraps the heat-resistant fiber wiping block 905, the sponge pad can cushion and protect the wiping block, preventing damage caused by the wiping block colliding with the inner wall of the protective box due to vibration. At the same time, the sponge pad has a certain absorption capacity, which can absorb the water mist remaining on the surface of the wiping block, keep the wiping block dry, and improve the wiping effect of the next time.

[0050] The workflow of this embodiment is as follows: The film is unwound by the unwinding roller on one side of the oven 1, first enters the oven 1 through the inlet / outlet slot 2, passes through the top of the first drive roller 4 and then through the bottom of the first tension roller 504, then passes through the top of the second drive roller 4 and then through the bottom of the second tension roller 504, and finally passes through the top of the third drive roller 4. After exiting the oven 1 through the inlet / outlet slot 2 on the other side of the oven 1, it is wound up by the take-up roller on the other side of the oven 1. The method of film threading of the composite copper foil in the oven is changed by adjusting the film threading method. The parallel conveying path increases the drying time of the composite copper foil in the oven, improving drying efficiency. The hot air blower 604 is activated, allowing hot air to enter the main pipe 605, then through the connecting pipe 603 into the air nozzle 602, and finally sprayed out through the air box 601 to dry both sides of the film. Simultaneously, the infrared heating tube 606 is activated to further heat the film, enhancing the drying effect. Furthermore, rotating the transmission rod 5051 causes the auxiliary bevel gear 5053 to rotate, which in turn rotates the main bevel gear 5052, causing the threaded rod 502 to rotate and lifting the threaded block 503, thereby adjusting the tension. The tension of the film is adjusted by the height of the tension roller 504. The state of the film inside the oven 1 can be observed in real time through the heat-resistant glass 8. When the oven 1 is first heated, water mist will form on the inner wall of the heat-resistant glass 8, affecting the observation. The screw 902 can be rotated to move the screw seat 903, which will move the heat-resistant fiber wiping block 905 to wipe the inner wall of the heat-resistant glass 8, improving the observation effect. After long-term use and wear, the heat-resistant fiber wiping block 905 will no longer be in contact with the heat-resistant glass 8. The handle 9044 can be rotated to rotate the screw 9042, which will move the mounting plate 9043. The movement causes the heat-resistant fiber wiping block 905 to approach and re-engage with the heat-resistant glass 8, thereby improving the service life of the heat-resistant fiber wiping block 905. When the heat-resistant fiber wiping block 905 is not in use, it can be moved to the long groove 9062. The electric cylinder 9061 drives the protective box 9063 to extend and abut against the mounting plate 9043, enclosing the heat-resistant fiber wiping block 905 inside the protective box 9063, reducing the amount of impurities adhering to the heat-resistant fiber wiping block 905 and further improving its service life.
