Description

Technical Field

[0001] This invention relates to the field of flexible transparent conductive film coating technology, and in particular to a coating apparatus and method for flexible transparent conductive films. Background Technology

[0002] The production process of flexible transparent conductive films involves the deposition and film formation of conductive films. Existing deposition technologies for transparent conductive films include sputtering deposition, which involves a sputtering source. In the sputtering source, plasma is used to bombard the target material, causing atoms to be sputtered and deposited on the substrate. This method has advantages such as high film uniformity, strong adhesion, and the ability to deposit over large areas. The deposition methods include substrate deposition and roll-to-roll deposition of roll-to-roll materials.

[0003] Roll-to-roll sputtering is suitable for the deposition of flexible transparent conductive films over a wide range of applications. It involves controlling the roll material to pass through a sputtering source, where target atoms or molecules are sputtered out and deposited onto the roll surface to form a thin film. However, during roll-to-roll sputtering, dynamic tension fluctuations in the roll material or uneven target utilization can lead to film thickness variations. To ensure stable sputtering on the roll material, the roll material must be kept taut at all times. Simultaneously, the roll material at the deposition site needs to be laid on a deposition platform to support it, thereby improving the uniformity of the sputtered coating. Conventional flexible transparent conductive film deposition equipment is inconvenient for simultaneously tensioning and supporting the roll material, which can cause the roll material to detach from the support platform during tensioning, resulting in uneven coating. Therefore, this solution proposes a deposition apparatus and method for flexible transparent conductive films to address these issues. Summary of the Invention

[0004] In view of this, the present invention proposes a coating apparatus and method for flexible transparent conductive films to solve the technical problem that conventional coating apparatuses for flexible transparent conductive films are inconvenient to simultaneously support the roll material while tensioning it, which may cause the roll material to detach from the support platform during the tensioning process, resulting in uneven coating. Therefore, this solution specifically proposes a coating apparatus and method for flexible transparent conductive films to solve the above problems.

[0005] The technical solution of this invention is implemented as follows: This invention provides a coating apparatus for flexible transparent conductive films, including a base, a processing base, a side frame, a slide cylinder, a tensioning wheel assembly, a control component, a coating machine body, and a coating sputtering source, wherein,

[0019] A push block is slidably disposed on the base and inserted into one side of the insertion slot. The side of the push block near the lifting block is inclined, and the shape of the groove wall of the insertion slot is adapted to the shape of the push block.

[0020] An external frame is installed on one side of the base, and the cylinder is mounted on the external frame, with the telescopic end of the cylinder connected to the push block.

[0030] Two limiting baffles are disposed on the top of the processing seat, and the roll material passes between the two limiting baffles and abuts against the limiting baffles.

[0031] Based on the above technical solutions, the preferred embodiment also includes a telescopic component, an assembly arch frame, a second heater, and a belt guide plate, wherein...

[0032] A telescopic component is provided on the base, and the telescopic end of the telescopic component is connected to the processing seat;

[0033] An assembly arch is provided on top of the processing base and located on the side near the infeed end of the coating machine body, and the roll passes through the inside of the assembly arch.

[0034] The second heater is located inside the assembly arch and is used to heat the top of the roll material.

[0035] A strip guide plate is disposed on the assembly arch and located on the side near the infeed end of the coating machine body. The strip guide plate is a triangular plate. The adjacent side walls of the strip guide plate abut against the top of the roll material, and the ends of the adjacent side walls of the strip guide plate extend to the outside of the roll material.

[0036] This invention also proposes a coating method for flexible transparent conductive films, which is completed using the aforementioned coating apparatus for flexible transparent conductive films, and includes the following steps:

[0037] S1. Pass the roll material through the two connection ports and wrap the roll material around the top of the processing seat. At this time, the roll material bends upward at the tensioning wheel set and fits against the top surface of the processing seat.

[0038] S2. Sputter coating treatment is performed on the roll material using a coating sputtering source;

[0039] S3. When the roll material is relaxed, the slide cylinder is raised by adjusting the components. The slide cylinder drives the processing seat and tensioning wheel group to move upward at the same time, thereby completing the tensioning process of the roll material.

[0040] The coating apparatus and method for flexible transparent conductive films of the present invention have the following advantages over the prior art:

[0041] (1) The coating apparatus for flexible transparent conductive film of this application is designed so that the roll material needs to pass around the tensioning wheel group when coating, and the tensioning wheel group is located above the connection port. Therefore, when the roll material needs to be tensioned, the tensioning wheel group only needs to be adjusted to move upward to complete the tensioning process of the roll material. Since the processing seat and the tensioning wheel group are both connected to the slide cylinder, the processing seat is set relative to the tensioning wheel group. Therefore, no matter what height the tensioning wheel group is adjusted to, the processing seat can support the bottom of the roll material, which increases the coating stability and uniformity of the coating of the roll material by the coating sputtering source.

[0042] (2) By setting up lifting blocks, specifically when it is necessary to raise the connecting frame, the extension end of the cylinder is adjusted to extend, the cylinder pushes the pushing block to move and squeeze the lifting block. Since one side of the pushing block is inclined, and the shape of the groove wall of the insertion slot matches the shape of the pushing block, the lifting block will be pushed upward when the pushing block squeezes the lifting block. The lifting block rotates along the connecting protrusion. Since the top wall of the lifting block abuts against the connecting frame, the top side of the lifting block will lift the connecting frame upward when the lifting block rotates, thereby completing the lifting process of the connecting frame. The coating device for flexible transparent conductive film of this application lifts the tensioning wheel group and the processing seat upward by using the pushing block to lift the lifting block. Since the force applied to the connecting frame by the tensioning wheel group and the processing seat is shared by the lifting block and the pushing block, the wear of the cylinder after the tensioning wheel group tensions the roll material can be reduced. Compared with the cylinder directly lifting the connecting frame, the service life of the cylinder is improved.

[0043] (3) By setting the connecting protrusion to be located inside the first assembly groove and rotatably connected to the slide rod, when the connecting protrusion rotates and lifts the connecting frame, the connecting protrusion will drop slightly relative to the first assembly groove. At this time, the slide rod slides along the sliding hole and drives the pressure plate to move downward. The pressure plate applies force to the force measuring device through the spring. The magnitude of the force is detected by the force measuring device, which makes it convenient for the user to read the magnitude of the tension force on the roll material. It is convenient to control the force applied to tension the roll material and prevent the roll material from deforming abnormally due to excessive tension force. It is convenient to use.

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0057] like Figures 1-10As shown, the coating apparatus for flexible transparent conductive films of the present invention includes a base 11, a processing seat 12, a side frame 21, a slide cylinder 22, a tensioning wheel assembly 3, an adjustment component 4, a coating machine body 51, and a coating sputtering source 52. The processing seat 12 is mounted on the base 11 and is used to support the roll material 10 in the vertical direction. The side frame 21 is mounted on one side of the processing seat 12, and the slide cylinder 22 is slidably mounted on the side frame 21, sliding along the height of the base 11. The slide cylinder 22 is fixed to the tensioning wheel assembly 3 and the processing seat 12. The tensioning wheel assembly 3 is located on one side of the processing base 12, and the roll material 10 passes over the top of the tensioning wheel assembly 3. The regulating component 4 is set on the base 11 and is used to regulate the sliding of the slide cylinder 22. The base 11 and the coating sputtering source 52 are both set inside the coating machine body 51. The coating machine body 51 has connection ports 511 at opposite ends for the roll material 10 to pass through. The height of the tensioning wheel assembly 3 is higher than the height of the connection port 511. The coating sputtering source 52 is positioned opposite to the processing base 12 and is used to coat the roll material 10 at the processing base 12.

[0058] In specific implementation, the side frame 21 is an L-shaped square frame. By setting the side frame 21 to be a square frame, the slide cylinder 22 cannot rotate relative to the side frame 21 when sliding, thereby increasing the sliding stability of the slide cylinder 22.

[0059] Preferably, the coating sputtering source 52 can be a sputtering source that completely covers the processing base 12, or multiple sputtering sources arranged in a row.

[0060] In practice, the roll 10 is passed through the two connection ports 511 and wrapped around the top of the processing seat 12. At this time, the roll 10 bends upward at the tensioning wheel assembly 3 and fits against the top surface of the processing seat 12. The roll 10 is then sputtered and coated by the coating sputtering source 52 positioned opposite to the processing seat 12. When the roll 10 is relaxed, the slide cylinder 22 is lifted upward by the adjusting component 4. The slide cylinder 22 drives the processing seat 12 and the tensioning wheel assembly 3 to move upward simultaneously, thereby completing the tensioning process of the roll 10.

[0061] The coating apparatus for flexible transparent conductive films of this application, by setting the roll 10 to pass around the tensioning wheel assembly 3 during coating, and the tensioning wheel assembly 3 being located above the connection port 511, can complete the tensioning of the roll 10 simply by adjusting the tensioning wheel assembly 3 to move upward when tensioning is required. Since both the processing seat 12 and the tensioning wheel assembly 3 are connected to the slide cylinder 22, the processing seat 12 is arranged relative to the tensioning wheel assembly 3. Therefore, regardless of the height of the tensioning wheel assembly 3, the processing seat 12 can support the bottom of the roll 10, increasing the coating stability and uniformity of the coating on the roll 10 by the coating sputtering source 52.

[0062] In a preferred embodiment, side frames 21 are provided on both sides of the base 11, and two slide cylinders 22 located on opposite sides of the base 11 are connected by a connecting frame 23, which is connected to the processing seat 12 by a first connecting rod 24.

[0063] By setting side frames 21 on both sides of the base 11, the feed inlet and discharge outlet of the processing seat 12 can be connected to tensioning wheel sets 3. The stacked tensioning wheel sets 3 simultaneously tension the roll material 10, thereby improving tension stability.

[0064] In a preferred embodiment, the tensioning wheel assembly 3 includes a force-applying wheel 31 and an auxiliary wheel 32, wherein the auxiliary wheel 32 is rotatably disposed below the force-applying wheel 31 and located on the side of the force-applying wheel 31 away from the processing seat 12, and the roll 10 is bent at the force-applying wheel 31.

[0065] In this design, the force-applying wheel 31 is the main component for bending the roll 10 to achieve tension. However, this application provides an auxiliary wheel 32 on one side of the bottom of the force-applying wheel 31. The auxiliary wheel 32 serves to limit the roll 10. Since the force-applying wheel 31 tensions the roll 10 by lifting it upwards, the roll 10 will continue to bend as the force-applying wheel 31 is used. In order to prevent the roll 10 from bending too much, which would cause wrinkles or damage and tearing, thus reducing the sputtering film formation effect, the auxiliary wheel 32 is provided to limit the excessive bending of the roll 10 at the force-applying wheel 31, thereby improving the stability of the device and making it easier to use.

[0066] In a preferred embodiment, it also includes a limiting ring 61 and a connecting body 62, wherein the two ends of the force-applying wheel 31 and the auxiliary wheel 32 are provided with limiting rings 61, which are used to cover the roll material 10; the force-applying wheel 31 and the auxiliary wheel 32 are rotatably mounted on the connecting body 62, and the connecting body 62 is fixedly connected to the slide cylinder 22.

[0067] Limiting retaining rings 61 are installed to limit the movement of the roll 10 from both sides, increasing the stability of the roll 10 during conveying. Connecting body 62 is installed to connect the force-applying wheel 31 and the auxiliary wheel 32, improving the position and connection stability of the wheel assembly.

[0068] In a preferred embodiment, the control component 4 includes a lifting block 41, a pushing block 42, a mounting frame 43, and a cylinder 44. A connecting protrusion 412 is formed on one side of the bottom of the lifting block 41, which is rotatably connected to the base 11. The top wall of the lifting block 41 is in contact with the connecting frame 23. A insertion groove 411 is provided on the side of the lifting block 41 away from the connecting protrusion 412. The pushing block 42 is slidably disposed on the base 11 and inserted into one side of the insertion groove 411. The side of the pushing block 42 near the lifting block 41 is inclined, and the shape of the groove wall of the insertion groove 411 matches the shape of the pushing block 42. Two pushing blocks 42 located on opposite sides of the base 11 are connected to each other via a second connecting rod 45. The mounting frame 43 is disposed on one side of the base 11, and the cylinder 44 is disposed on the mounting frame 43. The telescopic end of the cylinder 44 is connected to the pushing block 42.

[0069] Preferably, both the lifting block 41 and the pushing block 42 can be trapezoidal blocks.

[0070] In specific implementation, the connecting frame 23 includes a connecting frame 232 and bending frames 321 disposed at both ends of the connecting frame 232. By setting the bending frames 321 to bend outward, the connecting frame 232 can extend outward while connecting to the slide cylinder 22, which facilitates the connection with the lifting block 41.

[0071] Specifically, when it is necessary to raise the connecting frame 23, the telescopic end of the control cylinder 44 extends, and the cylinder 44 pushes the pushing block 42 to move and squeeze the lifting block 41. Since one side of the pushing block 42 is inclined, and the shape of the groove wall of the insertion groove 411 matches the shape of the pushing block 42, when the pushing block 42 squeezes the lifting block 41, it will push the lifting block 41 upward. The lifting block 41 rotates along the connecting protrusion 412. Since the top wall of the lifting block 41 abuts against the connecting frame 23, when the lifting block 41 rotates, the top side of the lifting block 41 will lift the connecting frame 23 upward, thereby completing the lifting process of the connecting frame 23.

[0072] The coating apparatus for flexible transparent conductive film of this application lifts the tensioning wheel assembly 3 and the processing seat 12 upward by pushing the lifting block 41 onto the platform of the pushing block 42. Since the force applied to the connecting frame 23 by the tensioning wheel assembly 3 and the processing seat 12 is shared by the lifting block 41 and the pushing block 42, the wear of the cylinder 44 after the tensioning wheel assembly 3 tensions the roll 10 can be reduced. Compared with the cylinder 44 directly lifting the connecting frame 23, the service life of the cylinder 44 is improved.

[0073] In a preferred embodiment, the system further includes a slide rod 71, a pressure plate 72, a force sensor 73, and a spring 74. The base 11 has a first mounting groove 111 at its top and a second mounting groove 112 inside. A sliding hole 113 is formed between the second mounting groove 112 and the first mounting groove 111. The slide rod 71 is slidably connected to the sliding hole 113. A connecting protrusion 412 is located inside the first mounting groove 111 and rotatably connected to the slide rod 71. A rotatable downward gap is formed between the first mounting groove 111 and the connecting protrusion 412. The pressure plate 72 is located inside the second mounting groove 112 and is fixedly connected to the slide rod 71. The force sensor 73 is disposed inside the second mounting groove 112 and connected to the pressure plate 72 via the spring 74.

[0074] By setting the connecting protrusion 412 to be rotatably connected to the slide rod 71 inside the first assembly groove 111, when the connecting protrusion 412 rotates and the connecting frame 23 is raised, the connecting protrusion 412 will simultaneously drop slightly relative to the first assembly groove 111. At this time, the slide rod 71 slides along the sliding hole 113 and drives the pressure plate 72 to move downward. The pressure plate 72 applies force to the force measuring device 73 through the spring 74. By measuring the force through the force measuring device 73, the user can easily read the magnitude of the tension force on the roll 10, which makes it easy to control the force applied to tension the roll 10 and prevent the roll 10 from deforming abnormally due to excessive tension force, making it convenient to use.

[0075] In a preferred embodiment, the telescopic end of the cylinder 44 is connected to the push block 42 by bolts, a limiting groove 114 is formed on the top of the base 11, and a limiting insert 421 is formed at the bottom of the push block 42, with the limiting insert 421 inserted into the inner side of the limiting groove 114.

[0076] This design allows the push block 42 to be detached. When the cylinder 44 needs maintenance or the push block 42 needs to be replaced, the bolts connecting the cylinder 44 and the push block 42 can be removed, and the push block 42 can be taken out upwards so that the limit insert 421 is disengaged from the limit slide groove 114, thus completing the disassembly of the push block 42.

[0077] The connection between the push block 42 and the base 11 is achieved by setting a limiting insert 421 that is inserted into the inner side of the limiting slide groove 114. Under the restriction of the groove wall of the limiting slide groove 114, the stability of the push block 42 moving on the base 11 can be increased.

[0078] It is necessary that the side slope of the pushing block 42 needs to be changed in real time according to the usage of this application. The ideal tension state of the roll 10 should be a certain tension force value, at which point the force measured by the force gauge 73 reaches the ideal value, and the force detected by the force gauge 73 will continuously increase during the movement of the pushing block 42. However, after the force detected by the force gauge 73 reaches a certain value, as the pushing block 42 continues to move, the pressure detected by the force gauge 73 still does not increase. At this time, the side slope of the pushing block 42 has come into contact with the bottom surface of the lifting block 41. In order to achieve the ideal tension state of the roll 10, the pushing block 42 needs to be replaced.

[0079] In a preferred embodiment, the system further includes a first heater 13 and a limiting baffle 14. The top of the processing base 12 is provided with a mounting groove 121, and a side baffle 122 is provided on the top periphery of the processing base 12. The first heater 13 is disposed inside the mounting groove 121 for heating the bottom of the roll 10. The two limiting baffles 14 are disposed on the top of the processing base 12, and the roll 10 passes between the two limiting baffles 14 and abuts against the limiting baffles 14.

[0080] This design limits the roll 10 from both sides by using the limiting baffle 14, which increases the stability of the roll 10 moving on the processing seat 12. The first heater 13 is set to heat the roll 10 by the positioning coating sputtering source 52, thereby improving the sputtering coating effect of the roll 10.

[0081] In a preferred embodiment, the system further includes a telescopic member 81, an assembly arch 82, a second heater 83, and a strip guide plate 84. The telescopic member 81 is mounted on the base 11, and its telescopic end is connected to the processing seat 12. The assembly arch 82 is mounted on the top of the processing seat 12 and is located near the end of the coil material 10 fed into the coating machine body 51, with the coil material 10 passing through the inside of the assembly arch 82. The second heater 83 is located inside the assembly arch 82 and is used to heat the top of the coil material 10. The strip guide plate 84 is mounted on the assembly arch 82 and is located near the end of the coil material 10 fed into the coating machine body 51. The strip guide plate 84 is a triangular plate, with its adjacent side walls abutting the top of the coil material 10, and the ends of its adjacent side walls extending to the outside of the coil material 10.

[0082] In specific implementation, a telescopic component 81 is connected between the base 11 and the processing seat 12 to improve the vertical stability of the processing seat 12. By setting a second heater 83 near the feed end of the coating machine body 51 to heat the top of the roll 10, the roll 10 can be preheated before sputtering coating. At the same time, the first heater 13 heats the roll 10 from both the top and bottom, improving the heating uniformity of the roll 10 and thus improving the sputtering coating effect of the roll 10, making it convenient to use.

[0083] This invention also proposes a coating method for flexible transparent conductive films, which is completed using the aforementioned coating apparatus for flexible transparent conductive films, and includes the following steps:

[0084] Step 1: Pass the roll 10 through the two connecting ports 511 and wrap the roll 10 around the top of the processing seat 12. At this time, the roll 10 bends upward at the tensioning wheel group 3 and fits against the top surface of the processing seat 12. At this time, the force wheel 31 bends and tensions the roll 10, and the auxiliary wheel 32 bends and limits the roll 10.

[0085] Step 2: Sputter coating treatment is performed on the roll material 10 using the coating sputtering source 52;

[0086] Step 3: When the roll material 10 is relaxed, the slide cylinder 22 is lifted upward by the control component 4. The slide cylinder 22 drives the processing seat 12 and the tensioning wheel group 3 to move upward at the same time, thereby completing the tensioning process of the roll material 10.
