Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a roller mold. Background Technology

[0002] Traditional roller molds used for processing light guide plate substrates mainly consist of a substrate with a microstructure surrounding the roller. If foreign matter (such as dust or oil stains) gets mixed in during the processing of the light guide plate substrate, it will cause defects in the roller mold, rendering the entire roller mold unusable. In this case, there is a problem of increased production costs and reduced production efficiency due to the scrapping of the entire roller mold. Utility Model Content

[0003] This application provides a roller mold that can solve the problem that existing roller molds become unusable due to defects, leading to increased production costs and reduced production efficiency.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a roller mold for processing light guide plate substrates. The roller mold includes a roller body and a feature structure layer. The roller body is equipped with a sensor for detecting the pressure applied during processing of the light guide plate substrate. The feature structure layer surrounds and is attached to the outer surface of the roller body. The feature structure layer includes multiple structural units, each of which has multiple microstructures on its surface away from the roller body. The multiple structural units are movably connected to the outer surface of the roller body.

[0006] This application provides another type of roller mold for processing light guide plate substrates. The roller mold includes a roller body and a feature structure layer; the roller body includes a roller shaft and multiple roller segments, which are detachably mechanically connected to the roller shaft. Each roller segment is equipped with a sensor for detecting the pressure applied during the processing of the light guide plate substrate by the roller mold; the feature structure layer includes multiple structural units, which are fixed one-to-one on the outer surface of the multiple roller segments. Each structural unit has multiple microstructures on its surface away from the corresponding fixed roller segment.

[0007] In the roller mold of this application embodiment, the design involves the movable connection between multiple structural units and the outer surface of the roller body, or the detachable mechanical connection between multiple roller segments and the roller shaft, with each structural unit fixed one-to-one to the outer surface of the multiple roller segments. This design ensures that if a structural unit has a defect, only that structural unit or its fixed roller segment needs to be replaced, preventing the entire roller mold from being scrapped. This reduces the scrap rate and cost of the roller mold and saves maintenance time and costs. Furthermore, optical testing can be performed on a localized portion of the light guide plate substrate to quickly detect which structural unit has a defect, reducing trial-and-error costs and improving production efficiency and product quality.

[0021] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating the application of a roller mold according to an embodiment of this application in processing a light guide plate substrate. Figure 2 This is a cross-sectional schematic diagram of the roller mold according to the first embodiment of this application. Figure 1 and Figure 2 As shown, the roller mold 100 is used to process the light guide plate substrate 50. Specifically, the roller mold 100 rolls the surface 51 of the light guide plate substrate 50 with a preset pressure, thereby forming an optical microstructure 52 on the surface 51 of the light guide plate substrate 50 that corresponds to the microstructure 60 of the roller mold 100. The roller mold 100 includes a roller body 110 and a feature structure layer 120. The roller body 110 is provided with a sensor 112, which is used to detect the pressure when the roller mold 100 processes the light guide plate substrate 50. The feature structure layer 120 surrounds and is attached to the outer surface 114 of the roller body 110. The feature structure layer 120 includes a plurality of structural units 122. Each structural unit 122 has a plurality of microstructures 60 on the surface 124 away from the roller body 110. The plurality of structural units 122 and the outer surface 114 of the roller body 110 are movably connected.

[0022] The feature structure layer 120 includes multiple structural units 122, and the multiple structural units 122 are movably connected to the outer surface 114 of the roller body 110, so that a defect 32 occurs in a certain structural unit 122 (e.g. Figure 1When the roller mold 100 is damaged (as shown), only the structural unit 122 needs to be replaced, which will not cause the entire roller mold 100 to be scrapped, thus reducing the scrap rate and cost of the roller mold 100 and saving maintenance time and costs. In addition, optical testing can be performed on a local light guide plate substrate 50, and the defective structural unit 122 can be quickly detected from the optical test results, reducing trial and error costs and improving production efficiency and product quality.

[0023] In one embodiment, the plurality of microstructures 60 may include concave microstructures and / or convex microstructures.

[0024] In one embodiment, the plurality of microstructures 60 may be frustum-shaped, sawtooth-shaped, wavy, semi-circular, or pyramidal, but are not limited thereto, and can be adjusted and designed according to actual needs. The forming method of the microstructures 60 may include, but is not limited to, electroplating, electroforming, injection molding, embedding, chemical vapor deposition (CVD), physical vapor deposition (PVD), etc., and can be adjusted and designed according to the material of the structural unit 122 and actual needs.

[0025] In one embodiment, the sensor 112 may be, but is not limited to, a resistance sensor, a piezoelectric sensor, a thermal sensor, a magnetic sensor, or an optical sensor, but is not limited thereto and may be adjusted and designed according to actual needs.

[0026] In one embodiment, each structural unit 122 may include a magnetic plate 70, on which the plurality of microstructures 60 are disposed. The roller body 110 may also be provided with a plurality of magnet units 80, which are used to magnetically attract the magnetic plate 70 of each structural unit 122 (e.g., ...). Figure 3 As shown, Figure 3 (This is a cross-sectional schematic diagram of the roller mold according to the second embodiment of this application). The magnetic plate 70 can be, but is not limited to, a steel plate or a nickel plate. In other words, the multiple structural units 122 and the roller body 110 can be magnetically connected.

[0027] In one embodiment, the roller mold 100 may further include an adhesive layer 90, and the plurality of structural units 122 are connected to the outer surface 114 of the roller body 110 via the adhesive layer 90 (e.g., ...). Figure 4 As shown, Figure 4 (This is a cross-sectional schematic diagram of the roller mold according to the third embodiment of this application). Each structural unit 122 may include a substrate 82, on which the plurality of microstructures 60 are disposed. The substrate of each structural unit 122 and the outer surface 114 of the roller body 110 can be movably connected by adhesive.

[0028] In one embodiment, the substrate 82 or the magnetic plate 70 may be polygonal in shape. The polygon may be, but is not limited to, rectangular or square, and can be adjusted and designed according to actual needs.

[0029] In one embodiment, the number of sensors 112 can be multiple, and the positions of multiple sensors 112 and multiple structural units 122 can be set one-to-one (e.g., Figure 3 and Figure 4 As shown in the figure, it can be adjusted and designed according to actual needs.

[0030] In one embodiment, the roller body 110 may include a roller shaft 116 and a plurality of roller segments 118, wherein the plurality of roller segments 118 are detachably mechanically connected to the roller shaft 116 to form an assembly, and a plurality of sensors 112 may be disposed one-to-one on the plurality of roller segments 118 (e.g., Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram illustrating the application of a roller mold, according to another embodiment of this application, in the processing of a light guide plate substrate. Figure 6 This is a cross-sectional schematic diagram of the roller mold according to the fourth embodiment of this application, but it is not limited thereto and can be adjusted and designed according to actual needs. For example, each roller segment 118 is provided with multiple sensors 112 inside. The multiple structural units 122 are movably connected one-to-one with the multiple roller segments 118, and the corresponding movably connected structural units 122 and roller segments 118 can constitute a microstructure module 10 (e.g., ...). Figure 7 As shown, Figure 7 for Figure 6 (A schematic diagram of an embodiment of a microstructure module consisting of a structural unit and a roller divider); In order to replace the structural unit 122 and its corresponding movable roller divider 118 when a defect occurs in the structural unit 122, a detachable mechanical connection is advantageous for the replacement.

[0031] In one embodiment, when each structural unit 122 includes a magnetic plate 70 and each roller segment 118 is provided with a magnet unit 80, the multiple structural units 122 and the multiple roller segments 118 can be movably connected by magnetic attraction (e.g., Figure 8 As shown, Figure 8 (This is a schematic diagram of an embodiment of the microstructure module of this application).

[0032] In another embodiment, each structural unit 122 can be movably connected between the adhesive layer 92 and the corresponding roller segment 118 (e.g., Figure 9 As shown, Figure 9 (This is a schematic diagram of another embodiment of the microstructure module of this application).

[0033] In one embodiment, the shape of the surface of each roller segment 118 that is movably connected to the corresponding structural unit 122 corresponds to the shape of the substrate 82 / magnetic plate 70 of the corresponding structural unit 122 (e.g., Figure 8 and Figure 9 (As shown).

[0034] In one embodiment, multiple structural units 122 are fixed one-to-one on the outer surface of multiple roller dividers 118, and each structural unit 122 has multiple microstructures 60 on the surface away from the corresponding fixed roller divider 118. Through the design of multiple roller dividers 118 being detachably mechanically connected to the roller shaft 116 and multiple structural units 122 being fixed one-to-one on the outer surface of multiple roller dividers 118, when a structural unit 122 is defective, only the module consisting of that structural unit 122 and its fixed roller divider 118 needs to be replaced, preventing the entire roller mold 100 from being scrapped. This reduces the scrap rate and cost of the roller mold 100 and saves maintenance time and costs.

[0035] As can be seen from the above embodiments, multiple structural units 122 can be fixed one-to-one on or movably connected to the outer surface of multiple roller dividers 118, and can be adjusted and designed according to actual needs.

[0036] In summary, the roller mold of this application, through the movable connection between multiple structural units and the outer surface of the roller body, or the detachable mechanical connection between multiple roller segments and the roller shaft, and the design of multiple structural units fixed one-to-one on the outer surface of multiple roller segments, ensures that when a structural unit has a defect, only that structural unit or the module consisting of that structural unit and its fixed roller segments needs to be replaced, without causing the entire roller mold to be scrapped. This reduces the scrap rate and cost of the roller mold, and saves maintenance time and costs. Furthermore, optical testing can be performed on a localized portion of the light guide plate substrate, thereby quickly detecting which structural unit has a defect, reducing trial-and-error costs, and improving production efficiency and product quality.
