Description

Technical Field

[0001] The present application belongs to the technical field of thin film cleaning, and in particular, relates to a thin film cleaning device. Background Art

[0002] For the transfer film used for laser transfer, the silver paste in the micron-sized semi-enclosed groove is difficult to be effectively cleaned and removed, and the transfer film is a large-scale roll film, and the cleaning process often requires high efficiency and no damage to the PE material.

[0003] At present, ultrasonic cleaning has been widely used in various fields. Its principle is that the ultrasonic generator sends out a high-frequency oscillation signal, which is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium - the cleaning liquid, thereby cleaning the objects placed in the cleaning liquid.

[0004] However, ultrasonic cleaning is mostly used to clean regular or irregular parts and products, and the cavitation effect generated by ultrasound washes away dirt such as rust and oil stains on the surface of the parts. For ultrasonic cleaning of silver paste, the existing technology mainly uses solvent immersion for several hours combined with ultrasonic vibration and spraying to clean the silver paste in the transparent mesh of the screen. However, there is no better solution for ultrasonic cleaning of silver paste on the transfer film. Utility Model Content

DETAILED DESCRIPTION

[0035] 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.

[0036] 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.

[0037] The present application provides a thin film cleaning device, referring to Figure 1-2 , comprising a cleaning tank body 1 filled with a cleaning agent, an ultrasonic generating component 2 arranged in the cleaning tank body 1, and a traction component 3;

[0038] The ultrasonic generating component 2 includes a vibration plate 21 and a plurality of vibrators 22 mounted on the vibration plate 21;

[0039] In the width direction of the film 4, the projection of the vibrator 22 on the film 4 can at least cover the entire width of the film 4;

[0040] The film 4 is transported into or out of the cleaning tank 1 by the traction assembly 3 , and the film 4 is transported in the cleaning tank 1 along the periphery of the ultrasonic wave generating component 2 .

[0041] In this embodiment, the film 4 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 part of the silver paste has solidified in the grooves. The cleaning agent contained in the cleaning tank 1 is a high-efficiency solvent-type cleaning agent that can cooperate with the ultrasonic generating component 2 to remove the residual silver paste on the film 4. 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 film cleaning device recorded in this embodiment can also be used to clean other films 4 (the film 4 with or without grooves can be cleaned using the film cleaning device recorded in this application), and the cleaning agent can be replaced for the stains remaining on the film 4. It is not limited to cleaning the silver paste remaining on the film 4.

[0043] The cleaning tank body 1 is also connected to the drain pipe 5 and the inlet pipe 6 respectively. The cleaning agent is injected into the cleaning tank body 1 through the inlet pipe 6, and the cleaning agent in the cleaning tank body 1 is discharged through the drain pipe 5, so that the cleaning agent in the cleaning tank body 1 is replaced regularly.

[0044] Before the film 4 is conveyed into the cleaning tank 1, a certain amount of cleaning agent is injected into the cleaning tank 1 through the liquid inlet pipe 6, and then the film 4 to be cleaned is conveyed into the cleaning tank 1 under the traction of the traction assembly 3, and passes around the ultrasonic generating component 2, that is, the film 4 passes at least from the two sides of the ultrasonic generating component 2 and the bottom of the ultrasonic generating component 2, so as to extend the walking path of the film 4 in the cleaning tank 1 and extend the ultrasonic cleaning time of the film 4. In this process, the projection of the vibrator 22 on the film 4 in the width direction of the film 4 can at least cover the entire width of the film 4, ensuring the uniformity of the energy density of the ultrasonic wave in the width direction of the film 4, so as to cooperate with the cleaning agent to clean the film 4 without dead angles, and the surface of the film 4 and the grooves on the surface of the film 4 after cleaning are highly clean, and the cleaning efficiency is high.

[0045] Furthermore, the vibration plate 21 is vertically arranged in the cleaning tank body 1, and the film 4 passes through the front and back sides of the vibration plate 21 in the cleaning tank body 1 in sequence, that is, the film 4 passes between the front side of the vibration plate 21 and the cleaning tank body 1 and then passes between the back side of the vibration plate 21 and the cleaning tank body 1, thereby extending the walking path of the film 4 in the cleaning tank body 1 to extend the cleaning time of the film 4.

[0046] like Figure 2 As shown, the ultrasonic generating component 2 also includes a shell 23 and a pipe 24 . The cable of the ultrasonic generating component 2 is housed in the pipe 24 to avoid direct contact between the cable and the cleaning agent. The vibration plate 21 and the vibrator 22 are both arranged in the shell 23 .

[0047] The vibrator 22 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 vibration plate 21, and the second vibrator group is arranged on the back side of the vibration plate 21;

[0048] The first vibrator group includes a plurality of first vibrators 221, and the second vibrator group includes a plurality of second vibrators 222. The projections of the plurality of first vibrators 221 in each group of the first vibrator group and the plurality of second vibrators 222 in the corresponding second vibrator group on the vibration plate 21 are arranged alternately.

[0049] In the width direction of the film 4 , the projections of the plurality of first vibrators 221 in each group of the first vibrator group and the plurality of second vibrators 222 in the corresponding second vibrator group on the film 4 can at least cover the entire width of the film 4 ;

[0050] When there are more than two of the first vibrator group and the second vibrator group, the first vibrators 221 in two adjacent first vibrator groups and the second vibrators 222 in two adjacent second vibrator groups are arranged in a staggered manner.

[0051] It can be understood that the multiple first vibrators 221 in the first vibrator group and the multiple second vibrators 222 in the second vibrator group are arranged along the width direction of the film 4, and the two adjacent first vibrators 221 in each group of the first vibrator group and the two adjacent second vibrators 222 in each group of the second vibrator group are arranged at an equal distance, so that the ultrasonic energy density acting in the width direction of the film 4 can be more uniform.

[0052] In order to achieve a better ultrasonic cleaning effect on the film 4 , in this embodiment, a plurality of first vibrator groups and a plurality of second vibrator groups are preferably provided on the front and back sides of the vibration plate 21 , respectively.

[0053] In order to better illustrate the present embodiment, the first vibrators 221 in the first group of first vibrator groups arranged on the front side of the vibration plate 21 are named a11, a12, a13, ... in sequence, the first vibrators 221 in the second group of first vibrator groups arranged on the front side of the vibration plate 21 are named a21, a22, a23, ... in sequence, and so on, the first vibrators 221 in the nth group of first vibrator groups arranged on the front side of the vibration plate 21 are named an1, an2, an3, ... in sequence; similarly, the second vibrators 222 in the first group of second vibrator groups arranged on the back side of the vibration plate 21 are named b11, b12, b13, ... in sequence, the second vibrators 222 in the second group of second vibrator groups arranged on the back side of the vibration plate 21 are named b21, b22, b23, ... in sequence, and so on, the second vibrators 222 in the nth group of second vibrator groups arranged on the back side of the vibration plate 21 are named bn1, bn2, bn3, ... in sequence.

[0054] In this way, the projection of b11 on the vibration plate 21 is between a11 and a12, the projection of b12 on the vibration plate 21 is between a12 and a13, the projection of a21 on the vibration plate 21 is between b21 and b22, the projection of a22 on the vibration plate 21 is between b22 and b23, and so on. In this way, in the width direction of the film 4, the projections of the multiple first vibrators 221 in each group of first vibrator groups and the second vibrators 222 in the corresponding second vibrator group on the film 4 can at least cover the entire width of the film 4, thereby ensuring the uniformity of the energy density of the ultrasonic wave acting on the film 4 and achieving dead-angle cleaning of the film 4.

[0055] Furthermore, in the width direction of the film 4 , the distance between two adjacent first vibrators 221 is less than or equal to the cross-sectional length of the second vibrator 222 , and the distance between two adjacent second vibrators 222 is less than or equal to the cross-sectional length of the first vibrator 221 .

[0056] That is, in the width direction of the film 4, 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 cross-sectional length between b11 and b12, and so on, so that in the width direction of the film 4, the projections of the multiple first vibrators 221 in each group of first vibrator groups and the multiple second vibrators 222 in the corresponding second vibrator group on the film 4 have no gaps, so that the entire width of the film 4 can be covered by the projections of the first vibrators 221 and the second vibrators 222, thereby avoiding strip-shaped stains remaining on the surface of the film 4 after cleaning.

[0057] Continue to refer Figure 1 The traction assembly 3 includes a feed roller 31 and a discharge roller 33 arranged outside the cleaning tank body 1, and a passing roller 32 arranged inside the cleaning tank body 1.

[0058] The film 4 to be cleaned is pulled into the cleaning tank 1 by the feed roller 31 , and is transported in the cleaning tank 1 by the roller 32 , and finally is transported out of the cleaning tank 1 by the discharge roller 33 .

[0059] In this process, the feed roller 31, the passing roller 32 and the discharge roller 33 can be rotated to drive the film 4 to be continuously transported along the running direction of the film 4, or the film 4 can be driven by a driving mechanism (not shown in the figure) to be transported along the running direction of the film 4, so that the movement of the film 4 drives the feed roller 31, the passing roller 32 and the discharge roller 33 to rotate continuously, and the film 4 and the feed roller 31, the passing roller 32 and the discharge roller 33 are all in a relatively static state to avoid damage to the film 4.

[0060] In this embodiment, the film 4 is preferably driven to move by a driving mechanism. Specifically, the incoming material of the film 4 to be cleaned is a coil, which is unwound by an unwinding mechanism (not shown in the figure), and the cleaned film 4 is reeled by a reeling mechanism (not shown in the figure), and the reeling mechanism serves as a driving mechanism for driving the film 4 to move. Before cleaning, one end of the coil is first pulled to the reeling mechanism through a feed roller 31, a passing roller 32, and a discharge roller 33 in sequence, and the reeling mechanism includes a reeling roller and a reeling driving mechanism that drives the reeling roller to rotate. During the cleaning process, the reeling driving mechanism drives the reeling roller to rotate, so that the film 4 is continuously conveyed to the cleaning tank body 1 through the feed roller 31, and is conveyed in the cleaning tank body 1 through the roller 32. After ultrasonic cleaning in the cleaning tank body 1, the film 4 is conveyed to the reeling mechanism for reeling after passing through the discharge roller 33.

[0061] The discharge roller 33 includes a pair of roller clamping mechanisms 331 and a plurality of hydrophilic rollers 332. Along the running direction of the film 4, the plurality of hydrophilic rollers 332 are arranged behind the pair of roller clamping mechanisms 331. The pair of roller clamping mechanisms 331 include two clamping rollers arranged opposite to each other. The two clamping rollers rotate in opposite directions. The cleaned film 4 passes through the middle of the two clamping rollers, and the front and back sides of the film 4 are in contact with the two clamping rollers respectively. Then, the film 4 passes through the plurality of hydrophilic rollers 332 in turn and is wound up at the winding mechanism.

[0062] Specifically, the clamping rollers are made of foam material, and the two clamping rollers rotate as the film 4 is conveyed, thereby removing the silver paste and cleaning agent remaining on the surface of the film 4. In this process, the clamping rollers and the film 4 are in a relatively static state, which can avoid damage to the film 4.

[0063] like Figure 1 As shown, there are three hydrophilic rollers 332, and all of them are made of hydrophilic sponges. After the film 4 passes through the roller clamping mechanism 331 to remove the silver paste and cleaning agent remaining on its surface, the three hydrophilic rollers 332 adsorb the very small amount of solution remaining in the grooves on the surface of the film 4 to ensure the cleanliness of the film 4 after cleaning and reduce the consumption of the cleaning agent. At the same time, due to the materials of the clamping roller and the hydrophilic roller 332 and the clamping roller, the hydrophilic roller 332 and the film 4 are in a relatively static state, the surface of the film 4 will not be damaged after passing through the clamping roller and the hydrophilic roller 332.

[0064] Of course, the number of the hydrophilic rollers 332 is not limited to three, and may be only one, two, or four, etc. The specific number depends on the actual situation.

[0065] In this embodiment, in order to further ensure that there is no moisture remaining on the surface of the film 4 rolled up by the winding mechanism, a drying component can be added between the hydrophilic roller 332 and the winding mechanism. The film 4 after passing through the hydrophilic roller 332 can be dried by the drying component to dry out any moisture that may remain on the surface of the film 4.

[0066] In this embodiment, two rollers 32 are provided, which are respectively arranged below the ultrasonic generating component 2, wherein one roller 32 is located on the side close to the front of the vibration plate 21, and the other roller 32 is located on the side close to the back of the vibration plate 21. The roller 32 includes a hard layer and a rubber layer, and the rubber layer is coated on the outside of the hard layer. The rubber layer can be made of rubber material. During the transmission process of the film 4, the rubber layer of the roller 32 contacts the surface of the film 4, which can absorb the tiny vibration generated by the ultrasonic wave, and avoid the film 4 from sliding relative to the roller 32 due to the vibration of the roller 32, thereby avoiding the generation of micron-level small crescent scratches on the surface of the film 4. 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.

[0067] For details, please refer to Figure 1 , the film 4 between the feed roller 31 and the roller 32 near the feed roller 31, the film 4 between the roller clamping mechanism 331 and the roller 32 near the roller clamping mechanism 331, and the vibration plate 21 are parallel to each other. It can be understood that the front of the vibration plate 21 faces the film 4 between the feed roller 31 and the roller 32 near the feed roller 31, and the back of the vibration plate 21 faces the film 4 between the roller clamping mechanism 331 and the roller 32 near the roller clamping mechanism 331. Of course, it is also possible that the back of the vibration plate 21 faces the film 4 between the feed roller 31 and the roller 32 near the feed roller 31, and the front of the vibration plate 21 faces the film 4 between the roller clamping mechanism 331 and the roller 32 near the roller clamping mechanism 331.

[0068] During the process of cleaning the film 4, the film 4 to be cleaned is conveyed to the cleaning tank 1 by the feed roller 31. When the film 4 is conveyed to the front of the vibration plate 21, the first vibrator 221 of the multiple groups of first vibrators arranged on the front of the vibration plate 21 is used in combination with the cleaning agent to clean the film 4. Then, under the traction of the two rollers 32, the film 4 passes between the ultrasonic generating component 2 and the bottom of the cleaning tank 1, and is then conveyed to the roller clamping mechanism 331 by the roller 32 close to the roller clamping mechanism 331. In this process, when the film 4 is conveyed to the back of the vibration plate 21, the second vibrator 222 of the multiple groups of second vibrators arranged on the back of the vibration plate 21 is used in combination with the cleaning agent to further clean the film 4, thereby cleaning the entire film 4 without dead angles, and extending the walking path of the film 4 in the cleaning tank 1 to extend the ultrasonic cleaning time of the film 4. The cleaning efficiency is high, and the cleaned film 4 has a high degree of cleanliness.

[0069] Through the above method, the conveying path of the film 4 can be increased within the limited space in the cleaning tank 1, the ultrasonic cleaning time of the film 4 in the cleaning tank 1 can be extended, and high-beat cleaning can be achieved, thereby improving the cleaning efficiency while reducing the volume of the cleaning tank 1. The reduction in the volume of the cleaning tank 1 can reduce the consumption of cleaning agent, which is beneficial to cost saving.

[0070] The equidistant arrangement between the film 4 in the tape running direction and the first oscillator 221 and the second oscillator 222 of the present application can ensure the uniformity of energy density during cleaning. Combined with a specific solvent-based cleaning agent and ultrasonic frequency, it can not only effectively remove the silver paste on the surface of the film 4, but also effectively remove the solidified silver paste in the micron-sized grooves on the surface of the film 4, so that the cleaned film 4 has a higher degree of cleanliness.

[0071] In addition, the vibration plate 21 of the present application can also be arranged horizontally in the cleaning tank body 1. In this case, the film 4 is transmitted into and out of the cleaning tank body 1 on the same side of the cleaning tank body 1. After the film 4 passes between the vibration plate 21 and the bottom of the cleaning tank body 1, it passes between the vibration plate 21 and the top of the cleaning tank body 1, and then is transmitted out of the cleaning tank body 1. In this case, four rollers 32 need to be arranged in the cleaning tank body 1.

[0072] Two vibration plates 21 of the present application can also be provided, and the two vibration plates 21 are distributed in an L shape, wherein one vibration plate 21 is provided opposite to the side wall of the cleaning tank body 1, and the other vibration plate 21 is provided opposite to the bottom of the cleaning tank body 1, wherein one vibration plate 21 is provided with a plurality of staggered first vibrators 221, and the other vibration plate 21 is provided with a plurality of staggered second vibrators 222, and the specific arrangement of the first vibrators 221 and the second vibrators 222 is consistent with the arrangement described in the aforementioned embodiment. In this way, in the width direction of the film 4, when the film 4 passes through the two vibration plates 21 in sequence, the projections of the first vibrators 221 and the second vibrators 222 on the film 4 together can at least cover the entire width of the film 4.

[0073] Of course, the two vibration plates 21 can also be arranged back to back, that is, the back surfaces of the two vibration plates 21 are arranged opposite to each other, and a plurality of first vibrators 221 are arranged on the front surface of one of the vibration plates 21, and a plurality of second vibrators 222 are arranged on the front surface of the other vibration plate 21, and the specific arrangement method is consistent with the above-mentioned embodiment.
