Description

Technical Field

[0001] This utility model relates to the field of evaporation coating equipment technology, and more specifically, to a roller cleaning mechanism, a winding device, and evaporation coating equipment. Background Technology

[0002] In related technologies, during evaporation coating, because the substrate being coated is relatively thin, it is easy for the substrate to be burned through when it is not cooled enough and comes into contact with large evaporation particles. Then, the large evaporation particles may adhere to the surface of the cold roller, which will threaten the subsequent coating process, such as tape breakage, thermal wrinkles and pitting caused by insufficient substrate cooling, etc., which seriously affect the quality of the finished film.

[0003] Currently, the cooling rollers are usually manually wiped bit by bit with polishing paste and cleaning cloth after the equipment is shut down and the chamber is opened. This is not only inefficient, but also difficult to completely remove the adhering substances from the surface of the cooling rollers.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] According to one embodiment of this application, a roller cleaning mechanism is provided. Figures 1 to 4 As shown, the roller cleaning mechanism includes a drive assembly 1 and a cleaning roller 2. The cleaning roller 2 is drivenly connected to the drive assembly 1. The drive assembly 1 can drive the cleaning roller 2 to abut against the surface of the roller body 6. The cleaning roller 2 can rotate relative to the roller body 6, or the drive assembly 1 can drive the cleaning roller 2 to detach from the surface of the roller body 6.

[0035] In this example, the driving component 1 drives the cleaning roller 2 to abut against the surface of the roller body 6, causing the roller body 6 to rotate. This allows the cleaning roller 2 to automatically remove adhering substances from the surface of the roller body 6. When the cleaning roller 2 needs to be replaced or repaired, the driving component 1 can detach the cleaning roller 2 from the roller body 6, thereby increasing the operating space. The roller cleaning mechanism of this application can improve the cleaning efficiency and effect on the roller body 6.

[0036] In this example, roller 6 can be a cooling roller, with the substrate wound around its lower side. An evaporation boat is also positioned below the cooling roller for evaporating and coating the substrate surface. Cleaning roller 2 abuts against the upper side of roller 6, with its axis parallel to the axis of roller 6. The length of cleaning roller 2 and roller 6 can be the same. During continuous coating of the substrate, roller 6 can rotate to allow cleaning roller 2 to clean the surface of roller 6.

[0037] In this example, the surface of the cleaning roller 2 is provided with multiple adhesive layers. That is, the cleaning roller 2 includes a roller shaft, and multiple adhesive layers are wound around the outside of the roller shaft. These adhesive layers can remove large particles adhering to the surface of the roller body 6, thereby achieving the effect of cleaning the surface of the roller 2. For example, the adhesive layer can be tape, with the sticky side in contact with the surface of the roller body 6. Before each use, the dirty part of the adhesive layer can be peeled off, exposing the clean adhesive layer, thus improving the cleaning effect. By providing multiple adhesive layers on the surface of the cleaning roller 2, the operation is simple; only the dirty part of the adhesive layer needs to be peeled off before each use.

[0038] In one example, such as Figure 1 The roller cleaning mechanism further includes a first mounting member 3, and the drive assembly 1 further includes a first connecting member 11 and a drive member. The first connecting member 11 is rotatably connected to the first mounting member 3. One end of the first connecting member 11 is rotatably connected to the cleaning roller 2, and the other end is drively connected to the drive member. The cleaning roller 2 and the drive member are respectively located on both sides of the first mounting member 3.

[0039] like Figure 1 As shown, in this example, the cleaning roller 2 is rotatably connected to one end of the first connecting member 11. The first connecting member 11 is located on one side of the axial direction of the cleaning roller 2, so that when the cleaning roller 2 is in contact with the roller body 6, the cleaning roller 2 abuts against the roller body 6, and the roller body 6 rotates, thereby driving the cleaning roller 2 to rotate, thus reducing the friction between the cleaning roller 2 and the roller body 6. For example, a connecting rod is provided at one end of the cleaning roller 2 along the axial direction, and the connecting rod is rotatably connected to the first connecting member 11.

[0040] The end of the first connecting member 11 furthest from the cleaning roller 2 is drive-connected to the driving member. The first connecting member 11 is rotatably connected to the first mounting member 3, for example, the middle position of the first connecting member 11 is rotatably connected to the first mounting member 3. The driving member drives the first connecting member 11 to rotate around the first mounting member 3, thereby driving the cleaning roller 2 to abut against or move away from the roller body 6.

[0041] For example, the first connecting member 11 is located above the roller body 6. The first connecting member 11 can be a rod structure, with its two opposite ends being a first end and a second end, respectively. The first mounting member 3 is rotatably connected between the first end and the second end. The cleaning roller 2 is connected to the first end, and the driving member is driven to the second end. The driving member drives the second end to rotate downward, thereby driving the first end to rotate downward, so that the cleaning roller 2 abuts against the roller body 6.

[0042] In this example, the first mounting member 3 can be a bearing housing, and the first mounting member 3 is fixedly connected to the fixing device. The first connecting member 11 is rotatably connected to the first mounting member 3 through the bearing, thereby improving the smoothness of the rotation of the first connecting member 11.

[0043] In one example, such as Figure 3 and Figure 4 As shown, the first connecting member 11 is bent along its length. By bending the first connecting member 11, the roller body 6 can be avoided, which facilitates the rational layout of the cleaning mechanism. For example, the first connecting member 11 includes a first straight section and a second straight section, which are connected by a bent section. The bent section is rotatably connected to the first mounting member 3. The end of the first straight section away from the bend is rotatably connected to the cleaning roller 2, and the end of the second straight section away from the bend is drive-connected to the driving member.

[0044] The bending section between the first and second straight segments can be bent upwards. Of course, the bending angle and direction of the bending section can be determined by those skilled in the art based on the actual situation, and no specific limitations are made here.

[0045] In one example, such as Figures 1 to 4 As shown, the driving component includes an elastic element 12, one end of which is connected to the first connecting element 11. The elastic element 12 can drive the first connecting element 11 to rotate around the first mounting element 3.

[0046] like Figures 1 to 4As shown, in this example, the driving component can be an elastic element 12. One end of the elastic element 12 acts on the end of the first connecting member 11 away from the cleaning roller 2, and can drive the first connecting member 11 to rotate around the first mounting member 3, thereby driving the cleaning roller 2 to abut against the surface of the roller body 6. For example, the elastic element 12 can be a tension spring, one end of which is connected to the first connecting member 11 and can pull one end of the first connecting member 11 to rotate upward, thereby driving the end connected to the cleaning roller 2 to rotate downward. When it is necessary to clean the cleaning roller 2, the elastic element 12 can be disengaged from the first connecting member 11, and the cleaning roller 2 can be easily pushed away from the roller body 6 to rotate, so as to facilitate cleaning the cleaning roller 2.

[0047] In one example, such as Figure 2 As shown, the roller cleaning mechanism also includes a second mounting member 4. The end of the elastic member 12 away from the first connecting member 11 is connected to the second mounting member 4. The second mounting member 4 is provided with multiple connection positions. The length of the elastic member 12 can be adjusted by connecting to different connection positions.

[0048] In this example, one end of the elastic element 12 is connected to the first connecting member 11, and the other end is connected to the second mounting member 4. The second mounting member 4 has multiple connection positions, and the elastic element 12 can be connected to different connection positions to adjust the force exerted by the elastic element 12 on the first connecting member 11, thereby adjusting the pressure applied by the cleaning roller 2 to the surface of the roller body 6. For example, by connecting one end of the elastic element 12 to different connection positions, the length of the elastic element 12 can be adjusted to adjust the elastic force of the elastic element 12. The second mounting member 4 can be fixedly mounted on the fixing seat 5, and both ends of the fixing seat 5 can be fixedly mounted to the inner wall of the cavity.

[0049] In this example, the force applied to the first connector 11 can also be further adjusted by replacing the elastic element 12 with one of different elasticity.

[0050] In one example, such as Figure 2 As shown, the second mounting component 4 includes a first mounting block 41 and a second mounting block 42. One end of the elastic member 12 is connected to the first mounting block 41, and the first mounting block 41 is adjustablely connected to the second mounting block 42.

[0051] like Figure 2As shown, in this example, one end of the elastic element 12 is connected to the first mounting block 41. The first mounting block 41 is provided with a second connecting hole 412, and the second mounting block 42 is provided with a third connecting hole 423. The first mounting block 41 can be connected to the third connecting hole 423 through the second connecting hole 412, thereby being able to connect to the second mounting block 42. The second mounting block 42 is provided with a plurality of third connecting holes 423 at intervals. By connecting the first mounting block 41 to the third connecting holes 423 at different positions, different connection positions can be formed.

[0052] For example, multiple third connecting holes 423 are gradually moved away from the first connector 11, and the position of the first mounting block 41 can be adjusted to be closer to or further away from the first connector 11. One end of the elastic member 12 is connected to the first mounting block 41, and the other end is connected to the first connector 11, thereby enabling the length of the elastic member 12 to be adjusted.

[0053] like Figure 2 As shown, in this example, the first mounting block 41 is also provided with a first connecting hole 411, and one end of the elastic member 12 is provided with a hook, which can be hung in the first connecting hole 411, so as to facilitate the assembly and disassembly of the elastic member 12.

[0054] In this example, the driving component can also be a cylinder or a linear motor, etc. The output shaft of the cylinder or linear motor is connected to the first connecting member 11, so that the pressure of the cleaning roller 2 on the surface of the roller body 6 can be adjusted by the cylinder or linear motor.

[0055] In one example, such as Figure 1 As shown, there are two first connectors 11, and the two first connectors 11 are respectively connected to the two ends of the cleaning roller 2 along the axial direction.

[0056] like Figure 1 As shown, in this example, a first connecting member 11 is connected to each end of the cleaning roller 2 along the axial direction. Two first mounting members 3 are correspondingly provided, with the first connecting members 11 on both sides rotatably connected to their respective first mounting members 3. The driving member can synchronously drive the first connecting members 11 on both sides to rotate. By providing two first connecting members 11, the stability of the cleaning roller 2 can be improved.

[0057] In one example, such as Figure 1 and Figure 2 As shown, the drive assembly 1 also includes a connecting rod 13, with the ends of the two first connectors 11 away from the cleaning roller 2 respectively connected to the connecting rod 13.

[0058] like Figure 1 and Figure 2As shown, in this example, the drive assembly 1 also includes a connecting rod 13, and two first connecting members 11 are provided, with the ends of the two first connecting members 11 away from the cleaning roller 2 respectively connected to one end of the connecting rod 13. The connecting rod 13 can synchronously drive the two first connecting members 11 to rotate synchronously, thereby enabling the cleaning roller 2 to apply pressure evenly to the roller body 6.

[0059] In this example, the drive element can be connected to the connecting rod 13, so that the two first connecting elements 11 can be driven to rotate synchronously by one drive element.

[0060] like Figure 2 As shown, in this example, the drive assembly 1 further includes a second connector 14, through which the connecting rod 13 movably passes. The second connector 14 is also provided with a fourth connecting hole 141. The drive component can be an elastic element 12, one end of which is provided with a hook. The hook can be hung in the fourth connecting hole 141, thereby facilitating the assembly and disassembly of the elastic element 12.

[0061] In one example, such as Figure 1 As shown, the driving component is connected to the connecting rod 13, and multiple driving components are provided along the length direction of the connecting rod 13.

[0062] In this example, multiple driving components can be provided, spaced apart along the length of the connecting rod 13, thereby improving the reliability and stability of rotating the two first connecting members 11. For example, the driving component can be an elastic element 12, and multiple second mounting members 4 are spaced apart on the fixed base 5, with multiple second connecting members 14 correspondingly provided on the connecting rod 13. One end of each elastic element 12 is connected to a second mounting member 4, and the other end is connected to a second connecting member 14.

[0063] According to another embodiment of the utility model, a winding device is provided. This winding device includes the roller cleaning mechanism described in the above embodiment. Wherein, as... Figures 1 to 4 As shown, the roller cleaning mechanism includes a drive assembly 1 and a cleaning roller 2. The cleaning roller 2 is drivenly connected to the drive assembly 1. The drive assembly 1 can drive the cleaning roller 2 to abut against the surface of the roller body 6. The cleaning roller 2 can rotate relative to the roller body 6, or the drive assembly 1 can drive the cleaning roller 2 to detach from the surface of the roller body 6. By driving the cleaning roller 2 to abut against the surface of the roller body 6 through the drive assembly 1, the roller body 6 rotates, thereby automatically removing the adhering substances from the surface of the roller body 6. When it is necessary to replace or repair the cleaning roller 2, the drive assembly 1 can drive the cleaning roller 2 to detach from the roller body 6, thereby increasing the operating space. The roller cleaning mechanism of this application can improve the cleaning efficiency and cleaning effect of the roller body 6.

[0064] In this example, the winding device includes a roller body 6, which can be a cooling roller. The substrate is wound around the cooling roller, and the cleaning roller 2 can clean the cooling roller.

[0065] According to another embodiment of the present invention, an evaporation coating apparatus is provided. This evaporation coating apparatus includes the winding device described in the above embodiment.

[0066] In this example, the evaporation coating equipment includes a cavity and a cover plate. A winding device is installed on one side of the cover plate, and an evaporation boat is disposed inside the cavity. The cover plate can drive the winding device into the cavity and can seal the opening end of the cavity. The substrate is wound on the roller 6, and evaporation coating can be performed on the surface of the substrate inside the cavity. The cleaning roller 2 can clean the surface of the roller 6, thereby ensuring the coating quality of the substrate surface.

[0067] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
