DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] The present application provides a web film cleaning system, referring to Figure 1-3 , including a traction module 1 and an unwinding module 2, a cleaning tank 3, a rinsing tank 4 and a winding module 5 which are sequentially arranged along the conveying direction of the film 6;

[0037] The winding module 5 includes a buffer component 51 and a winding component 52;

[0038] The traction module 1 includes at least one dewatering roller 11, a plurality of passing rollers 12 and a plurality of conveying rollers 14, wherein the dewatering roller 11 is arranged between the rinsing tank 4 and the buffer assembly 51, the passing roller 12 is located in the cleaning tank 3 and the rinsing tank 4, and the conveying roller 14 is located on the conveying path of the film 6 outside the cleaning tank 3 and the rinsing tank 4;

[0039] The cleaning tank 3 is filled with cleaning agent, the rinsing tank 4 is filled with pure water, and both the cleaning tank 3 and the rinsing tank 4 are provided with an ultrasonic generating component 7;

[0040] The film 6 passes through multiple conveying rollers 14, multiple passing rollers 12 and at least one dewatering roller 11, so that the film 6 enters the cleaning tank 3 and the rinsing tank 4 in sequence by the unwinding module 2 for cleaning, and then the film 6 is dewatered by the dewatering roller 11, and then the film 6 is step-by-step wound by the cache component 51 and the winding component 52.

[0041] In this embodiment, the film 6 preferably refers to a transfer film used for laser transfer, and has grooves on its surface, and a large amount of silver paste remains in the grooves, and even part of the silver paste has solidified in the grooves. The cleaning agent contained in the cleaning tank 3 is a high-efficiency solvent-type cleaning agent that can cooperate with the ultrasonic generating component 7 to remove the residual silver paste on the film 6. This embodiment does not limit the specific type of the cleaning agent, as long as it can achieve the purpose of this application.

[0042] Of course, the roll film cleaning system recorded in this embodiment can also be used to clean other types of films 6 (the roll film cleaning system recorded in this application can be used to clean films 6 with or without grooves on the surface), as long as the incoming material is a roll material. For different stains remaining on the surface of the film 6, it is only necessary to replace the type of cleaning agent in the cleaning tank 3, and it is not limited to being used to clean the silver paste remaining on the surface of the film 6.

[0043] Specifically, the film 6 to be cleaned is unwound by the unwinding module 2 and first enters the cleaning tank 3. The ultrasonic generating component 7 in the cleaning tank 3 cooperates with the cleaning agent to clean the film 6 to remove the silver paste on the surface of the film 6 and in the groove. Then, the film 6 enters the rinsing tank 4. The ultrasonic generating component 7 in the rinsing tank 4 cooperates with pure water to rinse the film 6 to further remove the silver paste and cleaning agent remaining on the surface of the film 6. Subsequently, the water on the surface of the film 6 and in the groove is removed by the water removal roller 11. Finally, the cleaned film 6 is reeled by the reeling module 5. The entire cleaning process adopts continuous unwinding and step-by-step reeling, which is conducive to controlling the reeling process of the film 6.

[0044] The film 6 is cleaned by the cleaning system provided in the present application. The whole process has high cleaning efficiency and will not cause damage to the film 6. The surface of the obtained film 6 and the grooves on the surface of the film 6 have high cleanliness and can be used for secondary laser transfer.

[0045] like Figure 1 As shown, the unwinding module 2 includes an unwinding component 21 and a roll changing component 22 , and the roll changing component 22 is located between the unwinding component 21 and the cleaning tank 3 .

[0046] Specifically, the roll changing assembly 22 includes a roll changing platform. When a roll of film 6 is cleaned, the roll is manually connected and changed on the roll changing platform, so as to clean the next roll of film 6 to be cleaned.

[0047] The unwinding assembly 21 includes an unwinding roller (not shown in the figure) and an unwinding drive motor (not shown in the figure) for driving the unwinding roller to rotate. The film 6 to be cleaned is wound around the unwinding roller. Under the action of the unwinding drive motor, the film 6 is continuously released from the unwinding roller.

[0048] In this embodiment, an unwinding correction component (not shown in the figure) and an unwinding diameter detection component (not shown in the figure) are also provided at the unwinding component 21 to ensure a stable unwinding speed and to ensure that the position of the film 6 does not deviate during the unwinding process.

[0049] like Figure 3 As shown, the ultrasonic generating component 7 includes a vibration plate 71, a plurality of vibrators 72 disposed on the vibration plate 71, a housing 73 and a pipe 74. The vibration plate 71 and the vibrators 72 are both disposed in the housing 73. The cable of the ultrasonic generating component 7 is stored in the pipe 74 to prevent the cable from directly contacting the cleaning agent. In the width direction of the film 6, the projection of the vibrator 72 on the film 6 can at least cover the entire width of the film 6, and the film 6 is transmitted along the periphery of the ultrasonic generating component 7 in both the cleaning tank 3 and the rinsing tank 4.

[0050] Specifically, the vibration plate 71 is vertically arranged in the cleaning tank body 3 and the rinsing tank body 4, and the film 6 passes through the front and back of the vibration plate 71 in the cleaning tank body 3 and the rinsing tank body 4 in sequence, that is, the film 6 passes between the front of the vibration plate 71 and the corresponding tank body and then passes between the back of the vibration plate 71 and the tank body, so as to extend the walking path of the film 6 in the corresponding tank body, thereby extending the cleaning time of the film 6. The projection of the vibrator 72 of the present application on the film 6 can at least cover the entire width of the film 6, so that the film 6 can be cleaned without dead angles.

[0051] The vibrator 71 includes at least one first vibrator group and at least one second vibrator group, the first vibrator group is arranged on the front side of the vibrating plate 71, and the second vibrator group is arranged on the back side of the vibrating plate 71. In order to achieve a better ultrasonic cleaning effect of the film 6, the present application preferably arranges multiple first vibrator groups and multiple second vibrator groups on the front side and the back side of the vibrating plate 71, respectively.

[0052] Each group of first vibrator groups includes multiple first vibrators 721, and each group of second vibrator groups includes multiple second vibrators 722. The projections of the multiple first vibrators 721 in each group of first vibrator groups and the multiple second vibrators 722 in the corresponding second vibrator groups on the vibration plate 71 are arranged in an alternating manner; in the width direction of the film 6, the projections of the multiple first vibrators 721 in each group of first vibrator groups and the multiple second vibrators 722 in the corresponding second vibrator groups on the film 6 can at least cover the entire width of the film 6; the first vibrators 721 in two adjacent groups of first vibrator groups and the second vibrators 722 in two adjacent groups of second vibrator groups are arranged in an alternating manner.

[0053] It can be understood that the multiple first vibrators 721 in the first vibrator group and the multiple second vibrators 722 in the second vibrator group are arranged along the width direction of the film 6, and the two adjacent first vibrators 721 in each group of the first vibrator group and the two adjacent second vibrators 722 in each group of the second vibrator group are equidistantly arranged. This can make the ultrasonic energy density acting in the width direction of the film 6 more uniform, thereby cleaning the film 6 without dead angles and achieving a better cleaning effect.

[0054] In order to better illustrate the present embodiment, the first vibrators 721 in the first group of first vibrator groups arranged on the front side of the vibration plate 71 are named a11, a12, a13, ... in sequence, the first vibrators 721 in the second group of first vibrator groups arranged on the front side of the vibration plate 71 are named a21, a22, a23, ... in sequence, and so on, the first vibrators 721 in the nth group of first vibrator groups arranged on the front side of the vibration plate 71 are named an1, an2, an3, ... in sequence; similarly, the second vibrators 722 in the first group of second vibrator groups arranged on the back side of the vibration plate 71 are named b11, b12, b13, ... in sequence, the second vibrators 722 in the second group of second vibrator groups arranged on the back side of the vibration plate 71 are named b21, b22, b23, ... in sequence, and so on, the second vibrators 722 in the nth group of second vibrator groups arranged on the back side of the vibration plate 71 are named bn1, bn2, bn3, ... in sequence.

[0055] In this way, the projection of b11 on the vibration plate 71 is between a11 and a12, the projection of b12 on the vibration plate 71 is between a12 and a13, the projection of a21 on the vibration plate 71 is between b21 and b22, the projection of a22 on the vibration plate 71 is between b22 and b23, and so on. In this way, in the width direction of the film 6, the projections of the multiple first vibrators 721 in each group of first vibrator groups and the multiple second vibrators 722 in the corresponding second vibrator group on the film 6 together can at least cover the entire width of the film 6, thereby ensuring the uniformity of the energy density of the ultrasonic wave acting on the film 6 and achieving dead-angle cleaning of the film 6.

[0056] Further, in the width direction of the film 6, the distance between two adjacent first vibrators 721 is less than or equal to the cross-sectional length of the second vibrator 722, and the distance between two adjacent second vibrators 722 is less than or equal to the cross-sectional length of the first vibrator 721. In this embodiment, the shape and size of each first vibrator 721 and the shape and size of each second vibrator 722 are preferably set to be the same, and the shape and size of the first vibrator 721 and the shape and size of the second vibrator 722 are set to be the same, so that the first vibrator 721 and the second vibrator 722 can be arranged easily, and the uniformity of the energy density of the ultrasonic wave acting on the film 6 can be ensured.

[0057] It can be understood that, in the width direction of the film 7, the cross-sectional length of b11 is greater than or equal to the distance between a11 and a12, the cross-sectional length of a12 is greater than or equal to the distance between b11 and b12, and so on, so that in the width direction of the film 6, the projections of the multiple first vibrators 721 in each group of first vibrator groups and the multiple second vibrators 722 in the corresponding second vibrator group on the film 6 are seamless, so that the entire width of the film 6 can be covered by the projections of the first vibrators 721 and the second vibrators 722, thereby avoiding strip-shaped stains remaining on the surface of the film 6 after cleaning.

[0058] In order to ensure that the silver paste on the surface of the film 6 and in the groove is cleaned, at least two cleaning tanks 3 are provided in this embodiment. Along the conveying direction of the film 6, the cleaning agent concentration in the previous cleaning tank 3 is higher than the cleaning agent concentration in the next cleaning tank 3.

[0059] Taking into account the cost and cleaning effect, this application preferably adopts Figure 1 As shown, two cleaning tanks 3 are provided, namely a primary cleaning tank and a secondary cleaning tank. The cleaning agent concentration in the primary cleaning tank is higher than that in the secondary cleaning tank. Ultrasonic wave generating components 7 are provided in both the primary cleaning tank and the secondary cleaning tank.

[0060] The liquid inlet and liquid discharge port of the primary cleaning tank are respectively arranged at the bottom and top of the primary cleaning tank, and the liquid inlet and liquid discharge port of the secondary cleaning tank are respectively arranged at the bottom and top of the secondary cleaning tank. The primary cleaning tank and the secondary cleaning tank are both provided with a spray assembly 31, which is immersed in the cleaning agent, and the water outlet of the spray assembly 31 faces the surface of the film 6. It can be understood that the water outlet of the spray assembly 31 sprays the same cleaning agent as that in the primary cleaning tank or the secondary cleaning tank, so that during the ultrasonic cleaning of the film 6, the surface of the film 6 is sprayed by the spray assembly 31, which can further improve the cleaning effect of the film 6, and is conducive to cleaning the solidified silver paste on the surface of the film 6 and in the groove.

[0061] Specifically, the spray assembly 31 is respectively arranged on the film 6 conveying path between the front of the vibration plate 71 and the primary cleaning tank body and the secondary cleaning tank body, and is arranged on the film 6 conveying path between the back of the vibration plate 71 and the primary cleaning tank body and the secondary cleaning tank body. When the film 6 is conveyed to the spray assembly 31, the film 6 can be cleaned with the spray assembly 31 under the action of ultrasonic waves, thereby improving the cleaning efficiency and reducing the residue of silver paste and cleaning agent on the surface of the film 6 after cleaning.

[0062] During the cleaning process, floating objects will gradually appear on the surface of the cleaning tank 3. The floating objects are mainly impurities and floating silver paste (most of the silver paste sinks to the bottom of the cleaning tank 3). In order not to affect the cleaning effect of the film 6, the floating objects on the surface of the cleaning tank 3 need to be removed.

[0063] To this end, the primary cleaning tank and the secondary cleaning tank are equipped with self-circulation components 8, each of which includes a circulation pump, a filter and a circulation pipeline. Taking the primary cleaning tank as an example, the discharge port of the primary cleaning tank is connected to the circulation pump, the filter and the liquid inlet of the primary cleaning tank in sequence through the circulation pipeline. Similarly, the discharge port of the secondary cleaning tank is also connected to the corresponding circulation pump, the filter and the liquid inlet of the secondary cleaning tank in sequence through the corresponding circulation pipeline.

[0064] Specifically, the cleaning agent containing floating objects generated during the cleaning process of the primary cleaning tank body and the secondary cleaning tank body overflows into the corresponding circulating pipes respectively, and the cleaning agent containing floating objects is transmitted to the corresponding filter along the corresponding circulating pipes through the corresponding circulating pumps, and the floating objects in the cleaning agent are removed by the filters. Then, the cleaning agent after the floating objects are removed is transmitted from the corresponding liquid inlet along the circulating pipes to the corresponding cleaning tank body again, thereby realizing self-circulating filtration of the floating objects in the cleaning agent.

[0065] Furthermore, the circulation pipeline can be connected to the liquid inlet of the corresponding cleaning tank body 3 and the corresponding spray assembly 31 arranged in the cleaning tank body 3, so that a part of the cleaning agent after removing the floating objects can be used for spraying the surface of the film 6, and the other part can be transmitted back to the corresponding cleaning tank body 3 for ultrasonic cleaning.

[0066] In addition, since the cleaning agent used is an organic solvent, odor will be generated during the cleaning process. In this application, an exhaust component 32 is provided above the cleaning tank 3 to discharge the odor generated during the cleaning process through the exhaust component 32. Specifically, the primary cleaning tank and the secondary cleaning tank may share one exhaust component 32, or each cleaning tank 3 may use one exhaust component 32 to discharge the corresponding odor.

[0067] Similarly, in order to further ensure that the silver paste and cleaning agent remaining on the surface and in the groove of the film 6 are removed, so that the final rolled-up film 6 has a higher degree of cleanliness, the present embodiment is provided with at least two rinsing tanks 4. Along the conveying direction of the film 6, the bottom of the last-stage rinsing tank 4 is provided with a water inlet 41, and the top of the first-stage rinsing tank 4 is provided with a water outlet 42. The pure water in the latter-stage rinsing tank 4 enters the former-stage rinsing tank 4 through overflow, so that the flow direction of the pure water is opposite to the conveying direction of the film 6. In this way, it can be ensured that the film 6 is gradually conveyed into the clean pure water during the step-by-step conveyance between the rinsing tanks 4. That is, when the film 6 is conveyed to the last-stage rinsing tank 4, the pure water in the last-stage rinsing tank 4 is the cleanest compared with the other stages of rinsing tanks 4, which can further improve the cleanliness of the surface and the groove of the cleaned film 6.

[0068] Taking into account the cost and rinsing effect, this application preferably adopts Figure 1 and Figure 2 As shown, two rinsing tanks 4 are provided, namely, a primary rinsing tank 43 and a secondary rinsing tank 44. Ultrasonic wave generating components 7 are provided in the primary rinsing tank 43 and the secondary rinsing tank 44. The water outlet 42 is provided at the top of the primary rinsing tank 43, and the water inlet 41 is provided at the bottom of the secondary rinsing tank 44. The top of the secondary rinsing tank 44 is connected to the bottom of the primary rinsing tank 43. Specifically, the flow path of pure water in the primary rinsing tank 43 and the secondary rinsing tank 44 is as follows: Figure 2 As shown, pure water enters the secondary rinsing tank 44 from the water inlet 41 , overflows from the top of the secondary rinsing tank 44 to the primary rinsing tank 43 , and finally overflows from the water outlet 42 at the top of the primary rinsing tank 43 .

[0069] The bottom of the primary rinsing tank 43 and the secondary rinsing tank 44 are both provided with an inlet and outlet assembly 45, which includes a pneumatic valve and a pump, and the inlet and outlet states of the corresponding tank are automatically controlled by the pneumatic valve and the pump. When the pure water in the primary rinsing tank 43 or the secondary rinsing tank 44 needs to be replaced, the pure water in the tank can be replaced by the correspondingly provided inlet and outlet assembly 45.

[0070] like Figure 1 As shown, in this embodiment, three dewatering rollers 11 are preferably provided. Of course, the number of dewatering rollers 11 provided may be less than three or more than three, and the specific number of dewatering rollers 11 provided may be determined according to the actual situation. The three dewatering rollers 11 are arranged in sequence along the conveying direction of the film 6, and are all made of hydrophilic sponges. The film 6 conveyed from the secondary rinsing tank 44 passes through each dewatering roller 11 in sequence to remove the residual water on the surface of the film 6 and in the groove.

[0071] In the actual cleaning process, a small amount of water will remain in the grooves on the surface of the film 6 after the water is removed by the water removal roller 11. In order to remove the small amount of water remaining in the grooves, the film 6 is transferred to the drying component 9 after the water is removed by the three water removal rollers 11. After the residual water in the grooves is removed by the drying component 9, it is transferred to the winding module 5 for winding. Specifically, the drying component 9 can blow out clean air, and the clean air blown out by the drying component 9 dries the water in the grooves. In order to further ensure that the residual water in the grooves is completely removed, the present application preferably sets two drying components 9 in sequence in the conveying direction of the film 6, and the film 6 passes through the two drying components 9 in sequence to remove the residual water in the grooves.

[0072] The winding module 5 of the present application includes a cache component 51, a winding component 52, a process correction component 53, a visual inspection component 54 and a code scanning component 55. The process correction component 53 is arranged on the film 6 transmission path between the drying component 9 and the cache component 51 to correct the deviation of the film 6 walking path during the transmission process and ensure that there is no deviation in the path before the film 6 is transmitted to the cache component 51.

[0073] The buffer assembly 51 includes a swing roller, which swings up and down to buffer the film 6 delivered to the buffer assembly 51, and releases the buffered film 6, so that the buffered film 6 continues to be delivered to the winding assembly 52. ​​The swing roller swings up and down to transform the continuous unwinding of the front section into the step-by-step winding at the winding assembly 52, which is more conducive to controlling the winding process and facilitates the visual inspection assembly 54 to visually inspect the film 6.

[0074] The visual inspection component 54 includes a detection platform and a visual inspection device located above the detection platform. The detection platform is located between the buffer component 51 and the winding component 52. The detection platform is provided with an adsorption device, which includes a plurality of adsorption holes opened on the upper surface of the detection platform, an adsorption cavity provided below the upper surface of the detection platform, and a vacuum device. The adsorption cavity is connected to the vacuum device, and the adsorption cavity is vacuumed by the vacuum device, so that the film 6 transferred to the detection platform is adsorbed. The visual inspection device is a prior art, and any device that can perform visual inspection on the film 6 can be used.

[0075] When the film 6 released by the cache component 51 is transferred to the detection platform, the film 6 is adsorbed on the detection platform through a vacuum device, which can ensure the accuracy of visual imaging. Then the film 6 is photographed by the visual detection device to detect the cleanliness of the surface of the film 6.

[0076] The roll material of the present application is formed by connecting and rolling multiple pieces of film 6 in the length direction of the film 6, wherein each piece of film 6 has a unique QR code in the region. The code scanning component 55 is arranged above the detection platform, and the result information of the visual inspection and the process parameters in the cleaning process are bound to the QR code and uploaded to the storage information through the code scanning component 55, so as to realize the complete quality parameter record of the whole roll of film 6, and facilitate the tracking of the subsequent laser transfer.

[0077] The winding assembly 52 includes a winding roller (not shown in the figure) and a winding drive mechanism (not shown in the figure) for driving the winding roller to rotate. The film 6 after visual inspection is wound up by the rotation of the winding roller. At the same time, the winding drive mechanism is also the power that drives the film 6 to be continuously transmitted from the unwinding assembly 21 to the winding assembly 52.

[0078] The winding component 52 is also provided with a winding correction component (not shown in the figure), a winding diameter detection component (not shown in the figure) and an encoder (not shown in the figure). A winding visual detection device can also be set up. The winding correction component, the winding diameter detection component, the encoder cooperate with the winding visual detection device to perform correction compensation, so as to realize step-by-step winding of the film 6 at the accurate position.

[0079] The unwinding correction assembly, unwinding roll diameter detection assembly, rewinding correction assembly, rewinding roll diameter detection assembly and encoder described in this embodiment are all prior art and will not be described in detail here.

[0080] Continue to refer Figure 1 The bottom of the primary cleaning tank, the secondary cleaning tank, the primary rinsing tank 43 and the secondary rinsing tank 44 are all provided with two rollers 12, and the two rollers 12 in each tank are respectively located on the front and back sides of the vibration plate 71, each roller 12 includes a hard layer and a rubber layer, the rubber layer is coated on the outside of the hard layer, and the rubber layer can be made of rubber. During the transmission of the film 6, the rubber layer of the roller 12 contacts the surface of the film 6, which can absorb the tiny vibrations generated by the ultrasonic wave, and avoid the film 6 from sliding relative to the roller 12 due to the vibration of the roller 12, thereby avoiding the generation of micron-level small crescent scratches on the surface of the film 6. The hardness of the hard layer and the thickness of the rubber layer can be designed according to the actual situation, and there is no specific limitation on their specific values.

[0081] The film 6 released by the unwinding assembly 21 is conveyed into the primary cleaning tank body by the conveying roller 14 located at the feeding end of the primary cleaning tank body, and is passed through two passing rollers 12 arranged in the primary cleaning tank body and the conveying roller 14 located at the discharging end of the primary cleaning tank body so that the film 6 passes in sequence between the front of the vibration plate 71 and the side wall of the primary cleaning tank body, between the bottom of the vibration plate 71 and the bottom of the primary cleaning tank body, and between the back of the vibration plate 71 and the side wall of the primary cleaning tank body, so as to extend the walking path of the film 6 in the primary cleaning tank body. Since vibrators 72 are provided on the front and back of the vibration plate 71, and the special arrangement as described above, the film 6 is cleaned without dead angles, and the silver paste on the surface and in the groove of the film 6 can be effectively removed. Then the film 6 is conveyed into the secondary cleaning tank body by the conveying roller 14 located between the primary cleaning tank body and the secondary cleaning tank body. Its walking path in the secondary cleaning tank body is the same as that in the primary cleaning tank body, and no detailed description is given here.

[0082] The film 6 after being cleaned in the secondary cleaning tank is transferred to the primary rinsing tank 43 via the transfer roller 14 located between the secondary cleaning tank and the primary rinsing tank 43, and then the film 6 after being rinsed in the primary rinsing tank 43 is transferred to the secondary rinsing tank 44 via the transfer roller 14 located between the primary rinsing tank 43 and the secondary rinsing tank 44. The walking path of the film 6 in the primary rinsing tank 43 and the secondary rinsing tank 44 is the same as its walking path in the primary cleaning tank, and will not be described in detail here.

[0083] The film 6 transferred out from the secondary rinsing tank 44 passes through three dewatering rollers 11 in sequence to remove water, and then passes through two drying components 9 in sequence. The film 6 is transferred between the two drying components 9 by a transfer roller 14. A plurality of transfer rollers 14 are arranged between the drying component 9 and the cache component 51, so that the dried film 6 is transferred to the cache component 51 for cache via the plurality of transfer rollers 14; a plurality of transfer rollers 14 are also arranged between the cache component 51 and the winding component 52, so that the film 6 released from the cache component 51 is transferred to the winding component 52 for winding.

[0084] like Figure 1 As shown, the traction module 1 further includes a plurality of roller clamping assemblies 13 , and the roller clamping assemblies 13 are located at the discharge ends of the cleaning tank body 3 and the rinsing tank body 4 .

[0085] Specifically, a pair of roller clamping mechanisms 13 are provided at the discharge end of the primary cleaning tank, the discharge end of the secondary cleaning tank, and the discharge end of the secondary rinsing tank 44. The pair of roller clamping mechanisms include two clamping rollers arranged opposite to each other. The two clamping rollers rotate in opposite directions. The film 6 transmitted from the corresponding tank passes through the middle of the two clamping rollers, and the front and back of the film 6 are in contact with the two clamping rollers respectively. Specifically, the clamping rollers are made of foam material, and the two clamping rollers rotate with the transmission of the film 6, so as to remove the silver paste and cleaning agent remaining on the surface of the film 6 after it comes out of the primary cleaning tank and the secondary cleaning tank, and remove the moisture remaining on the surface of the film 6 after it comes out of the secondary rinsing tank 44. In this process, the clamping rollers and the film 6 are in a relatively static state, which can avoid damage to the film 6.

[0086] In addition, the film 6 of the present application is continuously transferred from the unwinding component 21 to the winding component 52 under the action of the winding component 52, and the movement of the film 6 drives the dewatering roller 11, the passing roller 12, the clamping roller and the conveying roller 14 to rotate, so that the film 6 and the dewatering roller 11, the passing roller 12, the clamping roller and the conveying roller 14 are in a relatively static state, which can avoid damage to the film 6.
