Description

Technical Field

[0001] This application relates to the technical field of optical diffusion plates, and particularly to a calender roll adjusting device for preparing ultra-thin diffusion plates. Background Art

[0002] In the production and processing technology of optical diffusion plates, the production and processing technology of optical diffusion plates with a thickness of 0.8 mm - 3 mm has become relatively mature. For diffusion plates with a thickness of 0.8 mm, the problem of easy fracture and breakage during the production process of the diffusion plate product can be solved by adding toughening agents.

[0003] Optical diffusion plates with a thickness less than 0.8 mm can better save material costs. However, when the thickness is reduced to 0.55 - 0.70 mm, the technical difficulty is that the distance between the existing calender rolls is not easy to adjust, resulting in difficult adjustment of the pattern structure on the surface of the plate, thus causing a problem of poor surface appearance of the product.

[0035] The following describes the implementation manners of the present application through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0036] The following further describes in detail the specific implementation manners of the present application in conjunction with the accompanying drawings and embodiments.

[0037] Figure 1 The structural diagram of a calender roller adjusting device for preparing an ultra-thin diffusion plate according to an embodiment of the present application is shown. An embodiment of the present application provides a calender roller adjusting device for preparing an ultra-thin diffusion plate. As Figure 1 shown, the calender roller adjusting device for preparing an ultra-thin diffusion plate includes a translation base 1, a translation slide rail 2, a first slide plate 3, a second slide plate 4, a third slide plate 5, a first roller assembly 6, a second roller assembly 7, a third roller assembly 8, a first translation mechanism 9, and a second translation mechanism 10; wherein, the translation slide rail 2 is arranged on the translation base 1, both the first slide plate 3 and the third slide plate 4 are slidably connected to the translation slide rail 2, the first translation mechanism 9 and the second translation mechanism 10 are respectively connected to the first slide plate 3 and the third slide plate 5 for driving the first slide plate 3 and the third slide plate 5 to slide on the translation slide rail 2, the first translation mechanism 9 and the second translation mechanism 10 are arranged on the translation base 1, the second slide plate 4 is fixed on the translation slide rail 2, the second slide plate 4 is located between the first slide plate 3 and the third slide plate 5, and the first roller assembly 6, the second roller assembly 7, and the third roller assembly 8 are respectively fixed on the first slide plate 3, the second slide plate 4, and the third slide plate 5.

[0038] In this embodiment, the calender roll adjusting device for preparing an ultra-thin diffusion plate can realize the automatic adjustment of the spacing between three roll assemblies, thereby adjusting the pattern structure on the surface of the plate, ensuring the surface appearance quality of the diffusion plate product, and being particularly suitable for the calendering manufacturing process of low-thickness light diffusion plates. Specifically, for the calendering process of a certain ultra-thin diffusion plate, the calender roll adjusting device is used to first adjust the pairwise spacing between each roll assembly to determine the most suitable spacing. Under the determined most suitable spacing, the batch production and manufacturing of the ultra-thin diffusion plate are carried out with the adjusted spacing. During the debugging process, first, the second slide plate 4 is fixed. The fixing method of the second slide plate 4 includes but is not limited to being fixed to the translation slide rail 2 by locking screws. After the second slide plate 4 is fixed, by adjusting the first translation mechanism 9 and the second translation mechanism 10, the first slide plate 3 and the third slide plate 5 can slide on the translation slide rail 2, thereby adjusting the positions of the first slide plate 3 and the third slide plate 5 relative to the second slide plate 4. The first roll assembly 6, the second roll assembly 7, and the third roll assembly 8 are respectively fixed to the first slide plate 3, the second slide plate 4, and the third slide plate 5, so that the spacing between the first roll assembly 6 and the second roll assembly 7 and the spacing between the second roll assembly 7 and the third roll assembly 8 can be adjusted. After each adjustment is completed, the product indexes of the ultra-thin diffusion plates prepared corresponding to the spacing between the first roll assembly 6 and the second roll assembly 7 and the spacing between the second roll assembly 7 and the third roll assembly 8 can be recorded, and the spacing between the first roll assembly 6 and the second roll assembly 7 and the spacing between the second roll assembly 7 and the third roll assembly 8 corresponding to the optimal product indexes are selected as the optimal spacing. Subsequently, the ultra-thin diffusion plates of this model are uniformly configured according to the above spacing. When using the device provided in this embodiment to prepare ultra-thin diffusion plates, the first translation mechanism 9 and the second translation mechanism 10 can be adjusted to make the first slide plate 3 and the third slide plate 5 slide on the translation slide rail 2. When the spacing between the first roll assembly 6 and the second roll assembly 7 and the spacing between the second roll assembly 7 and the third roll assembly 8 reach the optimal spacing, the adjustment is stopped, and the first slide plate 3 and the second slide plate 5 are fixed. At this time, the ultra-thin diffusion plates are prepared with the optimal spacing, thereby ensuring the surface appearance quality of the product. If new models of ultra-thin diffusion plates need to be prepared, the above debugging process is repeated. After determining the optimal spacing, the distance between the three roll assemblies of the new model of ultra-thin diffusion plates can be set according to the determined optimal spacing.

[0039] It should be noted that the ultra-thin diffusion plate described in this article refers to a light diffusion plate with a thickness less than 0.8 mm. The distance between the first roller assembly 6 and the second roller assembly 7, and between the second roller assembly 7 and the third roller assembly 8 refers to the distance between the components acting on the surface of the diffusion plate in the first roller assembly 6 and the second roller assembly 7, and the distance between the components acting on the surface of the diffusion plate in the second roller assembly 7 and the third roller assembly 8. For example, the component of the first roller assembly 6 acting on the surface of the diffusion plate is usually a cylinder body, which is rotatable, has patterns on its surface and contacts the diffusion plate, and forms a pattern structure on the surface of the diffusion plate by rotational extrusion. Then the distance between the first roller assembly 6 and the second roller assembly 7 refers to the distance between the cylinder bodies of the first roller assembly 6 and the second roller assembly 7.

[0040] In some embodiments, to ensure the stability of the overall device in adjusting the distance and ensure that the three roller assemblies can rotate stably to implement the preparation of the pattern structure of the diffusion plate. As Figure 2 shown, the structure when setting the guiding base in a calender roller adjusting device for preparing an ultra-thin diffusion plate according to an embodiment of the present application is shown. The device further includes a guiding base 11, a guiding slide rail 12, a first guiding slide plate 13, a second guiding slide plate 14 and a third guiding slide plate 15; wherein, the guiding base 11 is symmetrically arranged with the translation base 1, a guiding slide rail 12 is arranged on the guiding base 11, the first guiding slide plate 13 and the third guiding slide plate 15 are slidably connected to the guiding slide rail 12, the second guiding slide plate 14 is fixed to the guiding slide rail 12, one ends of the first roller assembly 6, the second roller assembly 7 and the third roller assembly 8 are respectively fixed to the first slide plate 3, the second slide plate 4 and the third slide plate 5, and the other ends of the first roller assembly 6, the second roller assembly 7 and the third roller assembly 8 are respectively fixed to the first guiding slide plate 13, the second guiding slide plate 14 and the third guiding slide plate 15.

[0041] In this embodiment, by setting a guiding base 11 symmetric with the translation base 1, the guiding slide rail 12 arranged on the guiding base 11 is for slidably mounting the first guiding slide plate 13 and the third guiding slide plate 15 and fixedly mounting the second guiding slide plate 14. The first guiding slide plate 13, the second guiding slide plate 14 and the third guiding slide plate 15 are symmetric with the first slide plate 3, the second slide plate 4 and the third slide plate 5 respectively to fix both ends of the first roller assembly 6, the second roller assembly 7 and the third roller assembly 8, so that the three roller assemblies can be stably fixed, making their work more stable and also making the adjustment of the three roller assemblies more stable. Compared with the method of only setting a translation slide rail 2, adding a guiding slide rail 12 parallel to it can play a guiding role, making the translation directions of the third roller assembly 8 and the first roller assembly 6 in the set direction.

[0042] In some embodiments, a specific structure of three roller assemblies is provided.

[0043] As Figure 1 and Figure 2 shown, the first roller assembly 6 includes a first cylinder body 61, a first rotating shaft 62, a first fixing plate 63, a first mounting plate 64, and a first driving unit 65; wherein, the first rotating shaft 62 is coaxially connected to the first cylinder body 61, one end of the first rotating shaft 62 is rotatably arranged on the first fixing plate 63, the other end of the first rotating shaft 62 is connected to the power output end of the first driving unit 65, the first driving unit 65 is mounted on the first mounting plate 64, and the first fixing plate 63 is fixed to the first sliding plate 3.

[0044] In this first roller assembly 6, the way that the first rotating shaft 62 is coaxially connected to the first cylinder body 61 can be that the first cylinder body 61 is sleeved on the first rotating shaft 62 through a through hole provided at its axial center. The way that the first rotating shaft 62 is rotatably arranged on the first fixing plate 63 can be that a bearing seat is mounted on the first fixing plate 63, and one end of the first rotating shaft 62 is assembled in the bearing seat. The function of the first fixing plate 63 is to integrally fix the first roller assembly 6 on the first sliding plate 3, and the fixing method is detachable fixing, which is beneficial to the maintenance and replacement of the first cylinder body 61. The detachable fixing methods include but are not limited to assembly by bolts and screws. The function of the first driving unit 65 is to provide rotational power for the first cylinder body 61 through the first rotating shaft 62. The first driving unit 65 is usually selected as a power device with adjustable rotational speed and rotation direction, such as a servo motor, etc., and is not specifically limited here in this embodiment. The first cylinder body 61 is a roller applicable to the formation of the surface pattern structure of the diffusion plate, and patterns such as patterns and textures are provided on its surface. The size and shape of the specific pattern are determined according to the pattern structure of the prepared diffusion plate, and no specific examples are given here in this embodiment.

[0045] The second roller assembly 7 includes a second cylinder body 71, a second rotating shaft 72, a second fixing plate 73, a second mounting plate 74, and a second driving unit 75; wherein, the second rotating shaft 72 is coaxially connected to the second cylinder body 71, one end of the second rotating shaft 72 is rotatably arranged on the second fixing plate 73, the other end of the second rotating shaft 72 is connected to the power output end of the second driving unit 75, the second driving unit 75 is mounted on the second mounting plate 74, and the second fixing plate 73 is fixed to the second sliding plate 4.

[0046] The third roller assembly 8 includes a third cylinder body 81, a third rotating shaft 82, a third fixing plate 83, a third mounting plate 84, and a third driving unit 85; wherein, the third rotating shaft 82 is coaxially connected to the third cylinder body 81, one end of the third rotating shaft 82 is rotatably arranged on the third fixing plate 83, the other end of the third rotating shaft 82 is connected to the power output end of the third driving unit 85, the third driving unit 85 is mounted on the third mounting plate 84, and the third fixing plate 83 is fixed to the third sliding plate 5.

[0047] It should be noted that the assembly relationship of the parts included in the second roller assembly 7 and the third roller assembly 8 with the first roller assembly 6 is basically the same. Referring to the description of the specific structural composition principle of the first roller assembly 6 in the previous text, the specific structural composition principles of the second roller assembly 7 and the third roller assembly 8 will not be elaborated here.

[0048] It should be noted that the device realizes the formation of the surface pattern structure of the diffusion plate through three rollers (i.e., the first cylinder 61, the second cylinder 71, and the third cylinder 81). Although the working principles of the first cylinder 61, the second cylinder 71, and the third cylinder 81 are the same, their parameters are usually different. For example, the surface patterns, lengths, and diameters of the first cylinder 61, the second cylinder 71, and the third cylinder 81 may be different. Only as an example, as Figure 1 shown, the surface patterns of the second cylinder 71 and the third cylinder 81 are the same, the surface pattern of the first cylinder 61 is different from that of the second cylinder 71 and the third cylinder 81, and the length of the first cylinder 61 is shorter than that of the second cylinder 71.

[0049] It can be understood that the specific type selection of the first cylinder 61, the second cylinder 71, and the third cylinder 81 should be determined according to the manufacturing requirements of the actual product. Here in this embodiment, it is only an example and does not mean that during actual implementation, the cylinder structure shapes shown in the drawings must be selected.

[0050] In some embodiments, the specific structures of the first translation mechanism 9 and the second translation mechanism 10 are provided.

[0051] As Figure 2 and Figure 3 shown, the first translation mechanism 9 includes a first motor 91, a first lead screw 92, a first lead screw nut 93, and a first lead screw bearing seat 94; wherein, the power output end of the first motor 91 is connected to one end of the first lead screw 92, the other end of the first lead screw 92 is connected to the first lead screw bearing seat 93, both the first motor 91 and the first lead screw bearing seat 93 are arranged at the bottom end of the translation base 1, the first lead screw 92 is movably connected to the first lead screw nut 93, and the first lead screw nut 93 is fixedly connected to the first slide plate 3.

[0052] The second translation mechanism 10 includes a second motor 101, a second lead screw 102, a second lead screw nut 103, and a second lead screw bearing seat 104; wherein, the power output end of the second motor 101 is connected to one end of the second lead screw 103, the other end of the second lead screw 102 is connected to the second lead screw bearing seat 104, both the second motor 101 and the second lead screw bearing seat 104 are arranged at the bottom end of the translation base 1, the second lead screw 102 is movably connected to the second lead screw nut 104, and the second lead screw nut 104 is fixedly connected to the third slide plate 5.

[0053] The working principles of the first translation mechanism 9 and the second translation mechanism 10 are the same. Taking the second translation mechanism 10 as an example, when the second translation mechanism 10 is working, the power for translation is provided by the second motor 101. Among them, the second motor 101 is a motor capable of realizing forward and reverse rotation, such as a servo motor, etc. When the second motor 101 outputs torque in the clockwise direction, it drives the second lead screw 102 to rotate. At this time, the second lead screw nut 104 will move along the direction of the second lead screw 102. For example, Figure 2 in the figure, it moves downward along the second lead screw 102, and the third slide plate 5 connected to the second lead screw nut 104 will move together, so as to drive the third roller assembly 8 to translate.

[0054] In some embodiments, the first slide plate 3 includes an upper support plate 31, a lower support plate 32, a first vertical support plate 33, a second vertical support plate 34, and a component mounting plate 35; among them, the upper support plate 31 is connected to the lower support plate 32 through the first vertical support plate 33 and the second vertical support plate 34. The lower support plate 32 is located at the lower end of the translation slide rail 2, the upper support plate 32 is located at the upper end of the translation slide rail 2, the upper support plate 31 is fixedly connected to the component mounting plate 35, the first roller assembly 6 is fixed on the component mounting plate 35, the lower support plate 32 is connected to the first translation mechanism 9, the translation slide rail 2 includes a first slide rail 21 and a second slide rail 22, a first slider 23 and a second slider 24 are respectively slidably assembled in the first slide rail 21 and the second slide rail 22, and the first slider 23 and the second slider 24 are respectively connected to the first vertical support plate 33 and the second vertical support plate 34.

[0055] In this embodiment, through the structural design of the first slide plate 3, the overall structure can be made more compact. Specifically, the upper support plate 31 is arranged at the upper end / above the translation slide rail 2, and the upper support plate 31 does not contact the translation slide rail 2. Its function is to cooperate with the component mounting plate 35 to fix the first roller assembly 6. The lower support plate 32 is arranged at the lower end / below the translation slide rail 2 and does not contact the translation slide rail 2. Its function is to cooperate with the first translation mechanism 9 arranged at the bottom of the translation slide rail 2, so that the entire first slide plate 3 has the power to slide on the translation slide rail 2. The first vertical support plate 33 and the second vertical support plate 34 are used to connect the upper support plate 31 and the lower support plate 32. And the translation slide rail 2 adopts a double-slide rail design, so as to be connected to the upper support plate 31 and the lower support plate 32 through the first slider 23 and the second slide rail 24 respectively, ensuring that the first slide plate 3 can stably slide along the translation slide rail 2 under the drive of the first translation mechanism 9.

[0056] It should be noted that the second slide plate 4 and the third slide plate 5 can both adopt the same structure as the first slide plate 3, and the second slide plate 4 is not connected to the translation mechanism. The guide slide rail 12 can adopt the same structure as the translation slide rail 2, and the first guide slide plate 13, the second guide slide plate 14, and the third guide slide plate 15 can adopt the same structure as the first slide plate 3. Among them, the first guide slide plate 13, the second guide slide plate 14, and the third guide slide plate 15 are not connected to the translation mechanism.

[0057] In some embodiments, a debugging method for an ultra-thin diffusion plate is provided. This debugging method is based on the calender roll adjusting device for preparing an ultra-thin diffusion plate provided in any of the above embodiments. The purpose of this method is to determine the optimal spacing suitable for the preparation of the ultra-thin diffusion plate through the calender roll adjusting device proposed in this application. This method includes the following steps S1 to S6, which are introduced in detail as follows:

[0058] S1: Use a roll with a roughness of 10 - 30 μm as the middle roll (i.e., the second roll assembly), and a roll with a roughness of 4 - 20 μm as the rear roll (i.e., the third roll assembly), and the roll pattern depth Rz < 130;

[0059] S2: Debug the anti-collision roll limit; before starting the machine, adjust the calender roll limit to a first roll gap of 0.4 mm and a second roll gap of 0.3 mm. When debugging, a thin cotton cloth needs to be padded between the rolls to prevent equipment damage. Among them, the first roll gap is the minimum value of the distance between the first roll assembly and the second roll assembly, and the second roll gap is the minimum value of the distance between the second roll assembly and the third roll assembly.

[0060] S3: Start the machine and debug the product to 0.6 mm according to the method of debugging a 0.8 mm diffusion plate. That is, based on the spacing parameters for preparing a 0.8 mm diffusion plate, adjust the two spacing values so that the adjusted spacing values can meet the preparation of a diffusion plate with a thickness of 0.6 mm.

[0061] S3: Debug the roll temperature.

[0062] S4: Reduce the distance between the second roll assembly and the third roll assembly with a debugging amplitude of 0.02 - 0.05 mm, then increase the line speed. The calculation formula for the line speed increase range is: target line speed = current line speed * current plate thickness / (current plate thickness - reduced gap amplitude + 0.005). Finally, reduce the distance between the first roll assembly and the second roll assembly until the Bank accumulation is slightly visible;

[0063] S5: After the diffusion plate passes through the third roll assembly, confirm the appearance of the product. If the appearance is normal for 2 consecutive minutes, repeat step S4 until the target thickness. If there are problems with poor pattern transfer, it can be improved by appropriately adjusting the corresponding roll temperature, rotation speed ratio, etc., but care must be taken to prevent the sheet from breaking or wrapping the roll.

[0064] S6: Conduct inspections according to product requirements, and fine-tune various indicators such as the thickness, optics, and appearance of the sheet according to the inspection results, so as to determine the optimal spacing; among them, the optimal spacing is the spacing between two adjacent roller assemblies corresponding to the optimal values of various indicators.
