PI film can be used as insulation and packaging materials for flexible printed circuit boards, PTC heating films, TAB, electromagnetic wires, transformers, audio equipment, mobile phones, computers and other electronic and electrical products. During the processing of PI film, it is necessary to use a bonding device to apply pressure and heat to the bonding coil to complete the bonding process.

[0003] In the prior art, when the PI film is laminated, the PI film is usually laminated after being pressed and then heated by a heating roller to ensure a stable lamination. However, the use of the heating roller can only achieve short-term contact heating during the film winding process, and the film is in a continuous winding state, resulting in a large heat loss. The contact time with the film is short, the heating effect is not ideal, and the ideal lamination effect is often not achieved. Therefore, it is necessary to arrange multiple heating rollers on the production line to heat the film for a long time. This heating method is still in an open state, resulting in a large heat loss, and the arrangement cost is high, and the energy consumption is high during operation. Summary of the invention

[0022] A PI film simple and fast lamination production line lamination process, comprising the following steps:

[0023] S1. Select a PI film with a clean surface and good adhesion to the laminating surface, and then wrap it with the laminating coil and roll it on the unwinding roller;

[0024] S2, the PI film and the pasted coil pass through the arrangement path of the unwinding and winding components and the closing components. After the film passes through the support position and the pasting is completed, it is sent out from the drum to the winding roller position for winding.

[0026] S4, taking out the film from the winding roller position to complete the laminating process.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When the PI film is pasted, the film is rolled up in a ring state inside the drum. The film can be evenly contacted with the hot air inside the drum while being hot-pressed against the surface of the rotating tube. At this time, since the film is in a ring-shaped rolling state inside the drum, the film will evenly contact with multiple rotating tubes when rolling through the inside of the drum, and the winding path is long, so it will stay in the drum for a long time. Under the condition of a single set of heat source, long-term covering and heating of the film after pasting can be achieved, which has a better pasting effect on the film and saves energy.

[0029] 2. Since the outlet of the air nozzle is flat, the pressure exerted by the airflow is used to complete the lamination of the PI film and the lamination coil. The air jet is set to pressurize the film through the air nozzle position. The air jet setting can exert greater pressure on the film to ensure stable lamination of the film. At the same time, there is no direct contact with the surface of the film, avoiding wear of the film caused by direct pressure during lamination, thereby improving the processing quality of the PI film.

[0030] 3. The jet tube is supported by the annular tube and is in a state of annular distribution toward the film, so at this time the airflow can be ejected from multiple jet tube positions to act on the film surface. Since the film is between the jet tube and the rotating tube when it is rolled up, the jet tube can be used to apply pressure to the film in the direction of the rotating tube, so that the film and the rotating tube have a larger fitting surface, which has a better hot pressing effect on the film.

[0050] In this embodiment, since the outlet of the air nozzle 217 is in a flat state, the airflow blown out at this time can cover the surface of the film and apply pressure. At this time, the upper film is under pressure and supported by the lower bonding shaft 221 below. The pressure exerted by the airflow is used to complete the bonding processing of the PI film and the bonding coil.

At this time, the first heating wire 405 can heat the airflow entering the second connecting tube 404. After the heating is completed, the hot air will flow through the multiple first connecting tubes 403 and enter the multiple annular tubes 401. The jet tubes 402 are supported by the annular tubes 401 and are in a ring-shaped distribution state toward the film. Therefore, at this time, the airflow can be ejected from the positions of the multiple jet tubes 402 to act on the surface of the film. Since the film is in the position between the jet tube 402 and the rotating tube 612 when it is rolled up, the jet tube 402 can be used to apply pressure to the film in the direction of the rotating tube 612.

[0053] The use steps of the present invention are as follows: when the PI film is pasted, the PI film and the pasted coil are respectively unrolled at the unwinding roller 203 position, and the two films are guided and sent out through the support roller 205 and the first guide shaft 206 after unwinding, and then the two films pass through the support 219 between the upper laminating shaft 220 and the lower laminating shaft 221. When the PI film and the pasted coil pass through the support 219 position, the air jet 217 is used to apply pressure to the film to achieve the pasting of the two films, and then the second guide shaft 207 is used to send the film into the drum 302 from the inlet and outlet 304 position for heating. The interior of the drum 302 is composed of a guiding winding path formed by the setting of the rotating tube 612. Since the rotating tube 612 is arranged in a ring state, the state of the film at this time is as follows. Figure 3As shown, after the film is fed in from the inlet and outlet 304, it is sent out from the inlet and outlet 304 around the rotating tube 612. After the film is arranged, the closing cover 303 is closed, so that the inside of the drum 302 is in a closed state. When the film passes through the inlet and outlet 304, it is supported by the third guide shaft 621. Then, the film is rolled up to the winding roller 210. When the processing starts, the starting motor 208 can drive the winding roller 210 to rotate by the connection with the rotating shaft 209. The film can be rolled up along the above path by the rotation of the winding roller 210. During the rolling process, the first air pump 211, the second air pump 213, the first electric heating wire 405 and the second electric heating wire 618 are started synchronously. When the pump 213 is started, the air flow can be blown downward from the position of the air nozzle 217 through the connection of the second air outlet pipe 214, the connecting head 215 and the connecting cover 216. Since the outlet of the air nozzle 217 is in a flat state, the air flow blown out at this time can cover the surface of the film to apply pressure. At this time, the upper film is under pressure and supported by the lower bonding shaft 221 below. The pressure exerted by the air flow is used to complete the bonding process of the PI film and the bonding coil. The air jet at the position of the air nozzle 217 is used to apply pressure to the film for bonding. The air jet setting can apply greater pressure to the film to ensure that the film is stably bonded. At the same time, there is no direct contact with the surface of the film, which avoids wear of the film caused by direct pressure during bonding, thereby improving the processing quality of the PI film. After bonding, the film enters The film is rolled up inside the drum 302. During the rolling process, the film will be in a state of contact with multiple rotating tubes 612. The operation of the first air pump 211 can blow air into the cover body 506 through the connection of the first air outlet pipe 212. At this time, the airflow ejected from the first air outlet pipe 212 acts on the surface of the blade 510. After the blade 510 is stressed, it can drive the drive shaft 602 to rotate through the connection of the rotating rod 509. The rotation of the drive shaft 602 can drive the heating component 6 to follow the operation. The airflow blown out by the first air pump 211 when it is running can act on the inside of the drum 302 to heat and pressurize the film. At the same time, when the airflow is blown out, the force generated by the airflow can be used to drive the heating component 6. When the drive shaft 602 rotates, it can be driven by the first gear The connection of 603 drives the second gear 605 to rotate accordingly. When the second gear 605 rotates, it is supported by the driven rod 604. When the second gear 605 rotates, it can drive the second gear ring 610 to rotate accordingly. The second gear ring 610 drives the first gear ring 608 to rotate accordingly through the connection of the connecting block 609. When the first gear ring 608 rotates, it is supported by the matching setting of the extension rod 607 and the first plane bearing 606. The rotation of the first gear ring 608 can synchronously drive multiple rotating tubes 612 to rotate accordingly. When the rotating tube 612 rotates, it is supported by the setting of the rotating joint 611. At the same time, through the connection of the rotating joint 611, the rotating tube 612 and the connecting tube 502 are kept in a connected state. At this time, multiple rotating tubes 612 are in a rotating state at the same time.At the same time, the film is in a rolled-up state, so the rotation of the rotating tube 612 can be used to guide and support the film's rolling, ensuring that the film is in a ring state and is stably rolled up. After the airflow output by the first air pump 211 passes through the cover body 506 and is driven, the airflow will enter the connecting ring 503 through the exhaust pipe 507. The airflow entering the connecting ring 503 will flow through multiple connecting tubes 502 and the frame tube 505 respectively, and the airflow entering the connecting tube 502 will enter multiple rotating tubes 612 respectively. At this time, the airflow can be heated by using the second heating wire 618 inside the rotating tube 612, and the rotating tube 612 is heated at the same time. The second heating wire 618 is connected to the cover plate 615 and the second plane bearing 6 14 and the connection of the fixed plate 617, it can be kept in a fixed state and used inside the rotating tube 612. At this time, since the film and the surface of the rotating tube 612 are in a state of contact, the heat of the rotating tube 612 can be transferred to the film position for heating, and the hot air flowing through the rotating tube 612 position will be sent to the inside of the barrel 302 from the air outlet 616 position. At the same time, the rotation of the driving shaft 602 can synchronously drive the fan blade 619 and the spoiler 620 to rotate, and the rotation of the fan blade 619 can blow air toward the circular plate 501. Since the air outlet direction of the air outlet 616 position is toward the closing cover 303, the operation of the fan blade 619 can evenly diffuse the hot air toward the circular plate 501, and the spoiler 620 can also be used to blow air toward the circular plate 501. 0 can disturb the hot air so that the hot air is evenly filled in the barrel 302. At the same time, the exhaust valve 504 can be set to exhaust the inside of the barrel 302. Therefore, the film can be evenly in contact with the hot air filled in the barrel 302 while being hot-pressed against the surface of the rotating tube 612. At this time, since the film is in a winding state arranged in a ring inside the barrel 302, the film will be evenly in contact with multiple rotating tubes 612 when winding through the inside of the barrel 302, and the winding path is long, and it will stay in the barrel 302 for a long time. Under the condition of a single set of heat source, long-term covering and heating of the film after pasting can be achieved, which has a better pasting effect on the film and saves energy. The air is discharged at the position of the connecting ring 503. At the same time, the airflow ejected from the position of the rack tube 505 will enter the second connecting tube 404 for circulation. At this time, the first electric heating wire 405 can heat the airflow entering the second connecting tube 404. After the heating is completed, the hot air will flow through the multiple first connecting tubes 403 and enter the multiple annular tubes 401. The jet tubes 402 are supported by the annular tubes 401 and are in a state of annular distribution toward the film. Therefore, at this time, the airflow can be ejected from the multiple jet tubes 402 to act on the surface of the film. Since the film is in the position between the jet tube 402 and the rotating tube 612 when it is rolled up, the jet tube 402 can be used to press the film toward the rotating tube 612, so that the film and the rotating tube 612 have a larger contact surface, which has a better hot pressing effect on the film.
