[0071] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0072] Figure 1 is a top view schematic diagram of the application of a positioning module according to a first embodiment of the present invention, Figure 2 is a top view schematic diagram of the application of a positioning module according to a second embodiment of the present invention, Figure 3 is a side view schematic diagram of a positioning structure of a first embodiment of the present invention, Figure 4 is a schematic side view of a positioning structure according to a first embodiment of the present invention, wherein Figure 3 and Figure 4 The following is an example of a positioning structure having telescopic characteristics. Figure 1 As shown, the positioning module 1000 is suitable for the transport device 60, wherein the transport device 60 is, for example, disposed in front of the entrance of the roller press 70, that is, the roller press 70 and the transport device 60 are arranged along the Y axis, but not limited thereto. The positioning module 1000 includes a plurality of positioning structures 1 and at least two positioning platforms 36. The positioning module 1000 takes two positioning platforms 36 as an example, and the two positioning platforms 36 are respectively disposed on opposite sides of the transport device 60 along the X axis; the plurality of positioning structures 1 are respectively disposed on the two positioning platforms 36 in pairs, and the plurality of positioning structures 1 are, for example, arranged along the Y axis on each positioning platform 36.

[0073] Continuing with the above description, if Figure 3 and Figure 4As shown, each positioning structure 1 includes a support portion 10, a bushing 12, a guide column 14, a spring 16, a pivot 20 and a guide wheel 22. The support portion 10 includes a top end and a bottom end opposite to each other. The bushing 12 is connected to the top end of the support portion 10 and has a first opening O1 and a second opening O2 that are connected. The guide column 14 is movably arranged through the first opening O1 and the second opening O2, and at least a portion of the guide column 14 protrudes from the first opening O1. In one embodiment, the guide column 14 can be moved along the X-axis, for example. A first stopper 141 is formed on the portion of the guide column 14 protruding from the first opening O1, and the first stopper 141 is, for example, arranged in a ring and protruding from the column body of the guide column 14. The spring 16 is sleeved on the portion of the guide column 14 protruding from the first opening O1, and is between the bushing 12 and the first stopper 141, wherein one end of the spring 16 is connected to the first stopper 141, and the other end of the spring 16 is connected to the bushing 12, but is not limited thereto. The pivot 20 is connected to the protruding part of the guide column 14 and is located on the side of the first stopper 141 away from the spring 16. The pivot 20 is, for example, disposed along the Z axis through the protruding part of the guide column 14, but is not limited thereto. The guide wheel 22 is sleeved on the pivot 20 and is located on one side of the support portion 10. The guide wheel 22 is suitable for contacting the edge of the plate 80 transported by the transport device 60. In one embodiment, the positioning structure 1 further includes a stopper 121, which is disposed on the bushing 12 and is located around the first opening O1. The spring 16 is connected to the bushing 12 via the stopper 121. The stopper 121 can be suitable for preventing the spring 16 from penetrating into the bushing 12.

[0074] like Figure 2 As shown, the difference between the positioning module 1000A and the positioning module 1000 is that a plurality of positioning tables 36 are respectively arranged on opposite sides of the transport device 60A along the X-axis, and the number of the positioning tables 36 can be at most the same as the number of the positioning structures 1, and the plurality of positioning structures 1 located on the same side of the transport device 60A are not arranged on the same positioning table 36, for example, the positioning structures 1 are respectively arranged on different positioning tables 36, but is not limited thereto.

[0075] Continuing from the above description, the positioning module 1000 / 1000A can be applied to different types of transportation devices 60 / 60A, wherein Figure 1 The positioning module 1000 is shown as an example of a transportation device 60. Figure 2 The positioning module 1000A is used as an example of a transport device 60A, but the present invention is not limited thereto. The transport device 60 / 60A is suitable for transporting a plate 80, and the plate 80 is, for example, a transparent plate to be manufactured into an optical plate. The transport device 60 / 60A includes at least one transport support 62 and a plurality of transport rollers 64, each of which has a rotating shaft 641 and a wheel 642, and the wheel 642 is respectively disposed on both sides of the transport support 62 through the rotating shaft 641, but the present invention is not limited thereto. Figure 1As shown, there are two transport brackets 62, which are arranged opposite to each other, and the transport rollers 64 are arranged on both sides of the transport brackets 62 opposite to each other, and the wheels 642 arranged on the same side of the transport brackets 62 are arranged along the Y axis. Figure 2 In the transport device 60A shown, the transport device 60A further includes a sliding belt 66, two transport brackets 62 are arranged opposite to each other, the transport roller 64 is disposed between the two transport brackets 62, and the sliding belt 66 at least covers the wheel disc 642 to form a conveyor belt.

[0076] Continuing with the above description, if Figures 1 to 4 As shown, the guide wheel 22 of the positioning structure 1 faces the transport device 60 / 60A, and the position of the guide wheel 22 is higher than the wheel disc 642 of the transport roller 64. The guide wheel 22 is suitable for abutting against the edge of the plate 80. As the plate 80 is transported along the Y-axis direction, once the width of the plate 80 along the X-axis direction is greater than the distance between the two opposite guide wheels 22 of the positioning structure 1 respectively arranged on the two side positioning platforms 36, the guide wheel 22 is pushed by the external force applied by the plate 80 and approaches the support portion 10, and the guide column 14 is driven to move relative to the bushing 12 along the X-axis, so that a part of the guide column 14 protrudes from the second opening O2, and the first stopper 141 simultaneously approaches the bushing 12 and compresses the spring 16. In one embodiment, the positioning structure 1 further includes a second stopper 142, which is formed at one end of the guide column 14 away from the first stopper 141, so that the guide column 14 will not fall off when it moves relative to the bushing 12. Specifically, when the guide wheel 22 is pushed by external force and approaches the support portion 10, the guide column 14 is driven to move relative to the bushing 12 along the X-axis, and the spring 16 is squeezed by the first stop portion 141, the distance between the first stop portion 141 and the stop member 121 of the bushing 12 is shortened, a portion of the guide column 14 protrudes from the second opening O2, and the second stop portion 142 is away from the second opening O2; when the guide wheel 22 is not pushed by external force, the first stop portion 141 of the guide column 14 is pushed by the elastic force of the spring 16, and the guide column 14 is driven to move relative to the bushing 12 along the X-axis, the second stop portion 142 gradually approaches the second opening O2, and the guide wheel 22 gradually moves away from the support portion 10, and finally the second stop portion 142 abuts against the second opening O2 of the bushing 12, so that the guide column 14 stops moving, and does not cause the guide column 14 to continue to move toward the first opening O1 and disengage from the bushing 12.

[0077] Please continue reading Figure 3 and Figure 4As shown, in one embodiment, the positioning structure 1 further includes a base 18, which is connected to the bottom end of the support portion 10, suitable for allowing the positioning structure 1 to be stably located on a plane (such as a positioning platform 36), but is not limited thereto. In one embodiment, the positioning structure 1 further includes a fixing member 30, and the base 18 is provided with a fixing hole 32, and the fixing member 30 is passed through the fixing hole 32, so that the positioning structure 1 can be detachably set on a plane (such as a positioning platform 36), but is not limited thereto. In an embodiment not shown, the positioning structure 1 does not have a base 18, and a fixing groove is opened at the bottom end of the support portion 10, which is suitable for accommodating the fixing member 30, so that the fixing member 30 can detachably set the positioning structure 1A on a plane (such as a positioning platform 36).

[0078] Figure 5 is a side view schematic diagram of a positioning structure according to a second embodiment of the present invention, Figure 6 is a partial application side view of a positioning module according to a third embodiment of the present invention, Figure 7 is a partial application side view of a positioning module according to a third embodiment of the present invention. Figure 8 FIG. 1 is a schematic top view of a local application of a positioning module according to another third embodiment of the present invention. Figures 5 to 8 As shown, the difference between the positioning structure 1A and the positioning structure 1 is that the positioning structure 1A further includes a positioning piece 34, which is disposed on the side of the base 18 facing the guide wheel 22 and extends away from the support portion 10. The positioning piece 34 is suitable for stabilizing the positioning structure 1A to be disposed on a plane (such as a positioning platform 36), but is not limited thereto. Specifically, as Figure 6 As shown, the positioning piece 34 of the positioning structure 1A contacts the edge of the positioning platform 36, which is suitable for making the positioning structure 1A more stably arranged on the positioning platform 36. In an embodiment not shown, the positioning structure 1A does not have the base 18, and the support part 10 is seated on the positioning platform 36. The bottom end of the support part 10 is provided with a fixing groove, which is suitable for accommodating the fixing member 30, so that the fixing member 30 can detachably set the positioning structure 1A on the positioning platform 36.

[0079] In one embodiment, the setting of the positioning structure 1 / 1A can be understood as that when the transport device 60 / 60A is provided with additional platforms on the outer sides of the two transport brackets 62, multiple positioning structures 1 / 1A can be set on the platform, that is, the positioning platform 36 of the positioning module 1000 / 1000A can be omitted.

[0080] Please continue reading Figure 6The difference between the positioning module 1000B and the positioning module 1000 is that the positioning structure 1 in the positioning module 1000 is replaced by the positioning structure 1A, and the positioning module 1000B further includes at least two color sensors 50 respectively connected to one end of the pivot 20 of at least two positioning structures 1A located on different positioning platforms 36 near the guide wheel 22. Specifically, there are two color sensors 50, for example, and the two color sensors 50 are respectively disposed on the positioning structures 1A on the two positioning platforms 36 located on different sides of the transport device 60 / 60A, and at least one of the positioning structures 1A is away from the roller 70, but is not limited thereto. Figure 6 and Figure 7 As shown, taking the color sensor 50 connected to the positioning structure 1A as an example, there are multiple color sensors 50, and the color sensors 50 are respectively connected to the positioning structure 1A. The color sensor 50 is connected to one end of the pivot 20 adjacent to the guide wheel 22 by a connecting rod 501, and the color sensor 50 extends in a direction away from the support portion 10 and protrudes from the guide wheel 22. The color sensor 50 is suitable for detecting the surface state of the object to be positioned, and the object to be positioned is, for example, a plate 80, but is not limited thereto. The number of color sensors 50 is at most the same as the number of positioning structures 1A. In one embodiment, the color sensor 50 can also be connected to one end of the pivot 20 of the positioning structure 1 adjacent to the guide wheel 22.

[0081] See also Figure 1 , Figure 7 and Figure 8 As shown, the sheet 80 is placed on the transport device 60, and the sheet 80 is transported to the roller press 70 along the Y axis by the transport roller 64. The guide wheels 22 of the multiple positioning structures 1A provided on the positioning platforms 36 on both sides are suitable for contacting the edges of the sheet 80, and the guide wheels 22 rotate as the sheet 80 is transported. When the guide wheel 22 is pushed by the external force applied by the sheet 80, the guide wheel 22 approaches the support portion 10, for example but not limited to making the guide wheel 22 move along the X axis to between the wheel disc 642 on the outside of the transport bracket 62 and the positioning platform 36, and the actuation of the guide wheel 22 causes a portion of the guide column 14 to protrude from the second opening O2. Since the edges of both sides of the sheet 80 are abutted by the guide wheels 22, the sheet 80 will not be offset during the transportation process.

[0082] like Figure 7 and Figure 8 As shown, during the transportation process, when the width of the plate 80 along the X-axis varies, for example, the plate 80 is a trapezoid (for example Figure 7 ), rhombus, polygon, circle, or the edge of the plate is curved, convex, concave or wavy (such as Figure 8As shown, but not limited thereto, the guide post 14 of the positioning structure 1A will move relative to the bushing 12 when the guide wheel 22 contacts the edge of the plate 80 of different shapes. When the width of the plate 80 along the X-axis is small, the guide wheel 22 contacts the edge of the plate 80, and the spring 16 will not be compressed; when the width of the plate along the X-axis increases, the edge of the plate 80 will push the guide wheel 22, so that a portion of the guide post 14 protrudes from the second opening O2.

[0083] When the edge of the plate 80 abuts against the guide wheel 22, the color sensor 50 connected to the pivot 20 is located below the edge of the lower surface of the plate 80 that contacts the transport roller 64. In one embodiment, the upper surface of the plate 80 is, for example, a surface to be embossed with a pattern or microstructure, and the lower surface of the plate 80 is a surface that contacts the transport roller. The lower surface is, for example, provided with a protective film (not shown) to protect the lower surface. When the edge of the protective film is lifted or folded, when the roller press 70 presses the upper surface to form a pattern or microstructure, the lifted or folded portion of the protective film will damage the lower surface of the plate 80. The color sensor 50 irradiates an object with red, green, and blue (RGB) light, then receives the reflected light reflected from the surface of the object and converts the reflected light into sensing data. Since the reflected light changes due to the surface state of the object, the color sensor 50 is located below the edge of the lower surface of the plate 80, and detects the reflected light reflected from the lower surface and converts it into sensing data to determine whether the edge of the protective film is lifted or folded.

[0084] In one embodiment, the positioning module 1000B further includes a controller 52, which is adapted to be electrically connected to the color sensor 50 and the transport device 60 (eg, Figure 1 As shown in the figure, when the color sensor 50 transmits the sensing data to the controller 52, and when the controller 52 determines that the protective film on the lower surface of the plate 80 is warped or folded, the controller 52 stops the rotation of the transport device 60 to prevent the lower surface from being damaged during the printing process; on the contrary, when the plate 80 with the warped or folded protective film on the lower surface is removed, or the problem of the warped or folded protective film is solved, the controller 52 resumes the rotation of the transport device 60, thereby improving the production yield of the optical plate after printing.

[0085] Fig. 9 is a side view schematic diagram of a positioning structure according to a third embodiment of the present invention, Fig.10 is a top view schematic diagram of a positioning structure according to a third embodiment of the present invention, Fig.11 FIG. 1 is a partial bottom view schematic diagram of a positioning structure of a third embodiment of the present invention. Fig. 9As shown, the difference between the positioning structure 1B and the positioning structure 1A is that the positioning structure 1B further includes a housing 40, which is suitable for protecting internal components, such as: the support portion 10, the guide column 14, the bushing 12, the spring 16, the first stopper 141, the guide column 14 and the pivot 20, but is not limited thereto, so as to extend the service life of the positioning structure 1B. Figure 5 , Fig. 9 and Fig.10 As shown, the housing 40 includes an upright portion 42 and a transverse portion 44. The upright portion 42 covers the support portion 10, and the transverse portion 44 at least covers the bushing 12, the spring 16, the first stopper 141, a portion of the guide column 14, and a portion of the pivot 20; or, the transverse portion 44 at least covers a portion of the bushing 12, the stopper 121, the spring 16, the first stopper 141, a portion of the guide column 14, and a portion of the pivot 20. Fig.10 and Fig.11 As shown, the transverse portion 44 has a bottom surface with a sliding opening 441 formed thereon. An end of the transverse portion 44 away from the pivot 20 is provided with an opening 442. The sliding opening 441 is suitable for the pivot 20 to pass through, and the opening 442 is suitable for the guide post 14 to pass through. Figures 9 to 11 As shown, it can be understood that when the guide wheel 22 is pushed by the external force applied by the plate 80 and approaches the support portion 10, when the guide column 14 is actuated along the X-axis relative to the bushing 12, a portion of the guide column 14 will protrude from the second opening O2, the second stop portion 142 moves away from the hole 442, and the pivot 20 moves along the sliding opening 441 to approach the upright portion 42; when the guide wheel 22 is subjected to a reduction in the external force from the plate 80 or is not pushed by the external force, the guide column 14 moves toward the first opening O1, the second stop portion 142 finally abuts against the opening 442 of the outer shell 40, causing the guide column 14 to stop actuating, and the pivot 20 moves away from the upright portion 42 along the sliding opening 441.

[0086] Continuing with the above description, the housing 40 further includes a base portion 46 and a positioning portion 48. The base portion 46 covers the base 18, and the positioning portion 48 covers the positioning sheet 34. The base portion 46 has an opening 461 corresponding to the fixing hole 32 to facilitate the passage of the fixing member 30 and to detachably set the positioning structure 1B on the positioning platform 36, but is not limited thereto.

[0087] The present invention uses springs and guide pillars to make each positioning structure have telescopic characteristics, so that the positioning module is suitable for positioning plates of any shape, and the positioning structure is independently set on a positioning platform or a fixed bracket, so that the positioning module is used in combination with a transportation device. In addition, the color sensor and controller can improve the production yield by detecting the state of the protective film of the plate.

[0088] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. A person having ordinary knowledge in the technical field to which the present invention belongs may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
