[0062] Please refer to Figures 1 to 5 , Figure 1Schematic diagram of an inkjet printer 1 according to an embodiment of the present invention, Figure 2A Show Figure 1 Schematic diagram of the receiving container 110 of Figure 2B Show Figure 1 Top view of the receiving module 100 of Figure 3 Show Figure 2B Cross-sectional view of the receiving module 100 along the direction 3-3' of Figure 4 Show Figure 2B Schematic diagram of the filter 134 of Figure 5 Schematic diagram of a receiving module 200 according to another embodiment of the present invention.

[0063] As Figure 1 shown, the inkjet printer 1 includes an inkjet head device 10 and an inkjet device control unit 20. The inkjet printer 1 can be configured in or applied to, for example, an extended process of an optical film 30, an optical film coating process, an optical film laminating process, or an optical film cutting process. The inkjet head device 10 is electrically connected to the inkjet device control unit 20. The inkjet device control unit 20 is, for example, a physical circuit formed by a semiconductor process. The inkjet device control unit 20 can control the inkjet head device 10 to provide or eject an ink liquid L1 onto the optical film 30 to form a pattern, such as a linear pattern, a dot pattern, a text pattern, a symbol pattern, or a barcode pattern, such as a one-dimensional barcode or a two-dimensional barcode. The barcode contains information about the optical film 30, such as geometric information, optical properties, product information, or defect locations of the optical film 30. The ink liquid L1 is, for example, ink, and the ink has a color, such as black, red, or other colors.

[0064] In some embodiments, the optical film 30 is a roll-shaped material and is disposed on a roller 40 to be transported by the roller 40. In some embodiments, the inkjet head device 10 can be fixed, and by relying on the conveyance of the optical film 30 by the roller 40, a pattern can be printed on the optical film 30. In another embodiment, the optical film 30 is a sheet-like structure, and by moving the inkjet head device 10, a pattern can also be printed on the optical film 30. In another embodiment, the optical film 30 can also be moved by a roller or a moving platform, and a pattern can be printed by the fixed inkjet head device 10. That is, the optical film 30 and the inkjet head device 10 can move simultaneously or alternatively according to actual needs, and the present invention is not limited.

[0065] In some embodiments, the roller 40 can be configured in or applied to an optical film manufacturing process, such as an optical film extension process, an optical film coating process, an optical film laminating process, or an optical film cutting process.

[0066] In some embodiments, the optical film 30 may be a single-layer or multi-layer optical film. In some embodiments, the optical film 30 includes a polarizing plate, an optical property adjusting film, or a combination of the above. In some embodiments, the structure of the optical film 30 may include multiple film layers. In some embodiments, the optical film 30 includes a polarizing film, a protective layer, a surface protective layer, and a release layer, but the structure of the present invention is not limited thereto. For example, the protective layer may be omitted, or other polarizing films may be added.

[0067] In some embodiments, the pattern printed by the printing head device 10 may be formed on the surface of the polarizing film, the protective layer, the surface protective layer, or the release layer.

[0068] In some embodiments, the polarizing film may include polarizers. In some embodiments, the material of the polarizer may be a polyvinyl alcohol (PVA)-based resin, and the PVA-based resin can be obtained by saponifying polyvinyl acetate resin.

[0069] In some embodiments, the materials of the protective layer, the surface protective film, or the release layer may be, for example, thermoplastic resins with excellent transparency, mechanical strength, thermal stability, moisture barrier properties, etc. The thermoplastic resin may include acetyl cellulose resins (such as triacetate cellulose (TAC), diacetate cellulose (DAC)), acrylic resins (such as poly(methyl methacrylate) (PMMA)), polyester resins (such as polyethylene terephthalate (PET), polyethylene naphthalate), olefin resins, polycarbonate resins, cycloolefin resins, oriented-polypropylene (OPP), polyethylene (PE), polypropylene (PP), cyclic olefin polymer (COP), cyclic olefin copolymer (COC), polycarbonate (PC), or any combination of the above. In addition, surface treatment may be further performed on the protective layer, such as anti-glare treatment, anti-reflection treatment, hard coating treatment, antistatic treatment, or anti-fouling treatment, etc. In addition, in some embodiments, the protective layer is a single-layer or multi-layer optical film.

[0070] As Figure 1 and Figure 3As shown, the inkjet head device 10 includes an inkjet head 11 and a receiving module 100. The inkjet head 11 is disposed corresponding to the receiving module 100 and is used to provide printing liquid L1. The receiving module 100 is used to collect the leaked liquid L11 of the printing liquid L1 from the inkjet head 11. The receiving module 100 includes a receiving container 110, a leaked liquid collecting member 120, and a filtering device 130. The receiving container 110 has a receiving groove 110r. The leaked liquid collecting member 120 is disposed in the receiving groove 110r. The filtering device 130 is connected to the receiving container 110 and is used to filter the leaked liquid L11. The leaked liquid L11 contains at least one particle L11a. If the particle L11a escapes into the air, it may cause air pollution, and if it adheres to the optical film 30, it may cause poor quality of the optical film 30.

[0071] The leaked liquid collecting member 120 is, for example, disposed above the bottom surface 110s of the receiving groove 110r. In the receiving module 100 of the embodiment of the present invention, the leaked liquid collecting member 120 is used to capture the leaked liquid L11, and the filtering device 130 is used to recover the particle L11a in the leaked liquid L11, which can prevent the leaked liquid L11 from dripping onto the optical film 30, and can prevent the particle L11a of the leaked liquid L11 from polluting the air and / or the optical film 30. Generally, after the water in the leaked liquid L11 volatilizes, a large number of dust particles (particles L11a) with an outer diameter of less than 1 micron are formed. In this embodiment, due to the dust recovery effect of the receiving module 100, the number of dust particles with an outer diameter of 0.5 micron (including) or more can be less than 100.

[0072] As Figure 1 and Figure 3 shown, the inkjet head 11 has a corner 11C, and the bottom surface 110s of the receiving groove 110r corresponds to (e.g., is directly opposite to) the position of the corner 11C. The corner 11C is, for example, the lowest point of the inkjet head 11. Since the receiving groove 110r is aligned with the lowest point (e.g., the corner 11C) of the inkjet head 11, the leaked liquid L11 flowing along the bottom surface 11b of the inkjet head 11 can drip towards the bottom surface 110s after flowing to the printing corner 11C.

[0073] As Figure 2A and Figure 2B shown, the receiving container 110 has a first channel 110a and a second channel 110b. The leaked liquid collecting member 120 has a first end 121 and a second end 122. Depending on the structure of the leaked liquid collecting member 120, the first end 121 and the second end 122 are, for example, opposite ends of the leaked liquid collecting member 120. The first channel 110a communicates with the first end 121 of the leaked liquid collecting member 120, and the second channel 110b communicates with the second end 122 of the leaked liquid collecting member 120.

[0074] As Figure 2A , Figure 2B and Figure 3As shown, the receiving container 110 includes opposite first and second side plates 111 and 112, opposite third and fourth side plates 113 and 114, and a bottom plate 115. The first side plate 111, the second side plate 112, the third side plate 113, and the fourth side plate 114 are connected to the bottom plate 115. The first side plate 111, the second side plate 112, the third side plate 113, the fourth side plate 114, and the bottom plate 115 enclose a receiving groove 110r. The receiving groove 110r is, for example, in the shape of a cone. The third side plate 113 and the fourth side plate 114 connect the first side plate 111 and the second side plate 112. The first side plate 111 has a first bearing surface 111s, and the second side plate 112 has a second bearing surface 112s. The first end 121 of the liquid leakage collecting member 120 abuts against the first bearing surface 111s, and the second end 122 of the liquid leakage collecting member 120 abuts against the second bearing surface 112s.

[0075] As Figure 2A , Figure 2B and Figure 3 shown, a first channel 110a is formed in the first side plate 111. The first side plate 111 has an inlet 111a that communicates with the first channel 110a. The inlet 111a is, for example, connected to one end 110a1 of the first channel 110a, but may also be connected to any position between the opposite two ends 110a1 and 110a2 of the first channel 110a, such as a middle position or a position closer to one end 110a1. In addition, the first channel 110a communicates with the inner side surface and the first bearing surface 111s of the first side plate 111 to communicate with the first end 121 of the liquid leakage collecting member 120.

[0076] As Figure 2A , Figure 2B and Figure 3 shown, a second channel 110b is formed in the second side plate 112. The second side plate 112 has an outlet 112a that communicates with the second channel 110b. The outlet 112a is, for example, connected to one end 110b1 of the second channel 110b, but may also be connected to a position between the opposite two ends 110b1 and 110b2 of the second channel 110b, such as a middle position or a position closer to one end 110b1. In addition, the second channel 110b communicates with the inner side surface and the second bearing surface 112s of the second side plate 112 to communicate with the second end 122 of the liquid leakage collecting member 120.

[0077] As Figure 2A , Figure 2B and Figure 3As shown, an air flow G1 can enter the first channel 110a from the inlet 111a, then flow through the liquid leakage collector 120, enter the second channel 110b, and leave the receiving container 110 from the outlet 112a. The inlet 111a and the outlet 112a are respectively located on different sides of the first channel 110a and the second channel 110b. For example, the inlet 111a is located on the side of the fourth side plate 114, while the outlet 112a is located on the side of the third side plate 113, so that the inlet 111a and the outlet 112a are respectively close to the two diagonals of the liquid leakage collector 120. By the diagonal configuration of the inlet 111a and the outlet 112a, the air flow G1 can flow through most or the entire liquid leakage collector 120, increasing the probability of the air flow G1 carrying the particles L11a. In some embodiments, the air flow G1 can be provided by the existing compressed dry air (CDA) in the factory or generated by a gas generator (not shown).

[0078] In some embodiments, as Figure 2B and Figure 3 shown, the liquid leakage collector 120 is, for example, a mesh structure. For example, the liquid leakage collector 120 includes a plurality of solid lines that are intertwined into a mesh structure. The liquid leakage L11 will adhere to the lines of the mesh structure, increasing the residence time in the mesh structure, and thus increasing the probability of being carried away by the air flow G1. The aforementioned lines are, for example, made of plastic, metal, rubber or a combination thereof. Specifically, the liquid leakage collector 120 is, for example, a grid or a filter screen.

[0079] As Figure 2B and Figure 3 shown, the filtering device 130 further includes a first air flow generator 131 and a heater 132. The heater 132 communicates with the first channel 110a and the first air flow generator 131. The first air flow generator 131 can be connected to the aforementioned air flow G1 (such as compressed dry air), and the first air flow generator 131 can send the air flow G1 into the heater 132 for heating, so that the temperature of the air flow G1 rises. Then, the high-temperature air flow G1 enters the liquid leakage collector 120 from the first channel 110a, causing the moisture of the liquid leakage L11 adhering to the liquid leakage collector 120 to evaporate due to the high temperature, and leaving the particles L11a. Then, the remaining particles L11a will be sucked in by the second air flow generator 133 connected to the filter 134 and enter the filter 134 through the outlet 112a for filtering. In addition, the first air flow generator 131 is a pressure valve, a pump or a blowing element, such as a fan or other types of forced air flow generators. In some embodiments, the air flow G1 is generated by the pump of the first air flow generator 131 and then enters the heater 132 for heating.

[0080] In some embodiments, the setting of the first air flow generator 131 can also be omitted, and the air flow G1 can directly pass through the heater 132 for heating, so that the temperature of the air flow G1 rises.

[0081] As Figure 2B and Figure 3 shown, the filtering device 130 includes a second air flow generator 133 and a filter 134. The second air flow generator 133 communicates with the second channel 110b. The second air flow generator 133 can discharge (e.g., suck out) the air flow G1 from the liquid leakage collection member 120 to the air flow generator. During the process of flowing through the liquid leakage collection member 120, this air flow G1 can carry the particles L11a. The filter 134 is connected between the second channel 110b and the second air flow generator 133 and is used to filter the particles L11a carried by the air flow G1, so that the particles L11a remain in the filter 134, and the filtered air flow G1 can be discharged by the second air flow generator 133. In addition, the second air flow generator 133 can be a suction element, such as a suction machine, an exhaust fan or a pump, or other types of forced air flow generators.

[0082] Under the interaction (air supply and suction) of the first air flow generator 131 and the second air flow generator 133, more and / or stronger air flow G1 can flow through the liquid leakage collection member 120 to carry more particles L11a, reducing the probability of the particles L11a contaminating the air and / or the optical film 30. In some embodiments, depending on the actual situation, the filtering device 130 can omit the first air flow generator 131 and / or the heater 132. Or, in some other embodiments, depending on the actual situation, the filtering device 130 can omit the second air flow generator 133 and / or the filter 134.

[0083] As Figure 4 shown, the filter 134 includes a filter container 1341 and a filter element 1342. The filter container 1341 has an inlet 1341a, a first outlet 1341b and a second outlet 1341c. The inlet 1341a communicates with the receiving container 110, for example, communicates with the first channel 110a of the receiving container 110 (the first channel 110a is shown in Figure 2B) The filtering element 1342 is, for example, a filtering component such as a filter screen, a filter element, or a sponge, etc., which may include materials capable of adsorbing impurities, such as activated carbon, etc. The filtering element 1342 is disposed within the filtering container 1341 and is disposed adjacent to the first outlet 1341b. The first outlet 1341b can be selectively communicated with the second air flow generator 133. The filtering element 1342 can block the passage of the particles L11a of the leaked liquid L11. The air flow G1' passing through the filtering element 1342 has very few particles L11a, or even no particles L11a, and thus is a clean air flow. The second outlet 1341c is located at the bottom of the filtering container 1341, and the leaked liquid can be discharged out of the filtering container 1341 through the second outlet 1341c. Specifically, if the leaked liquid L11 carried by the air flow G1 condenses into the leaked liquid L11' within the filtering container 1341, it can be discharged from the second outlet 1341c. In addition, the filtering element 1342 and the inlet 1341a are spaced apart by a space SP1. Before the air flow G1 enters the filtering element 1342, the space SP1 provides more time for the leaked liquid (if any) carried by the air flow G1 to condense into a liquid, so that the air flow G1 entering the filtering element 1342 is as dry as possible, avoiding the blocking of the filtering element 1342 by moisture or liquid (if any).

[0084] As Figure 1 shown, the receiving module 100 further includes a controller 140. The controller 140 is electrically connected to the aforementioned first air flow generator 131, the heater 132, and the second air flow generator 133. The controller 140 is configured to: control the enabling or disabling of the generation of the air flow G1 by the first air flow generator 131, control the enabling or disabling of the generation of the air flow G1 by the second air flow generator 133, and control the enabling or disabling of the heating function by the heater 132. The controller 140 is, for example, a physical circuit formed by a semiconductor process.

[0085] As Figure 1As shown, the receiving module 100 further includes a liquid leakage sensor 150 and a warning device 160. The liquid leakage sensor 150 is disposed on the bottom surface 110s of the receiving groove 110r and is located below the liquid leakage collecting member 120, and is configured to generate a detection signal S1 when the liquid leakage L11 contacts the liquid leakage sensor 150 through the liquid leakage collecting member 120 (when the liquid leakage L11 is excessive). The warning device 160 is configured to issue a warning signal S2 according to the detection signal S1. In some embodiments, the aforementioned controller 140 is further electrically connected to the liquid leakage sensor 150 and the warning device 160. The controller 140 controls the warning device 160 to issue a warning signal S2 according to the detection signal S1. In another embodiment, without passing through the controller 140, the warning device 160 can directly issue a warning signal S2. For example, the liquid leakage sensor 150 can be electrically connected to the warning device 160. Based on the detection of the liquid leakage L11 by the liquid leakage sensor 150, the liquid leakage sensor 150 issues a detection signal S1, and the warning device 160 issues a warning signal S2 accordingly. In addition, the aforementioned warning signal S2 is, for example, various indication signals such as sound, colored light, vibration, etc. When the warning signal S2 is sound, the warning device 160 is, for example, a speaker; when the warning signal S2 is colored light, the warning device 160 is, for example, a light emitter; when the warning signal S2 is vibration, the warning device 160 is, for example, a vibrator.

[0086] As Figure 1 shown, the controller 140 can be electrically connected to the inkjet printing device control unit 20. Based on the detection of the liquid leakage L11 by the liquid leakage sensor 150, the controller 140 can notify the inkjet printing device control unit 20, and the inkjet printing device control unit 20 controls the inkjet head device 10 to stop operating to prevent more liquid leakage L11 from continuously occurring. In another embodiment, without passing through the controller 140, the inkjet printing device control unit 20 can directly control the inkjet head device 10 to stop operating. For example, the liquid leakage sensor 150 can be electrically connected to the inkjet printing device control unit 20. Based on the detection of the liquid leakage L11 by the liquid leakage sensor 150, the liquid leakage sensor 150 issues a detection signal S1, and the inkjet printing device control unit 20 controls the inkjet head device 10 to stop operating accordingly.

[0087] The aforementioned receiving container 110 is, for example, illustrated by a trapezoidal container, but the embodiments of the present invention are not limited thereto.

[0088] Please refer to Figure 5, which shows a schematic diagram of the receiving module 200 according to another embodiment of the present invention. The receiving module 200 includes a receiving container 210, a liquid leakage collecting member 120, a filtering device (including a first air flow generator 131, a heater 132, a filter 134, and a second air flow generator 133), a controller 140, a liquid leakage sensor 150, and a warning device 160 (not shown). The receiving module 100 of the foregoing inkjet printer 1 can be replaced by the receiving module 200. The receiving module 200 of the embodiment of the present invention has technical features similar to or the same as those of the foregoing receiving module 100, except that the receiving container 210 has a different structure.

[0089] As Figure 5 shown, the receiving container 210 includes opposite first side plates 111 and second side plates 112, opposite third side plates 113 (not shown) and fourth side plates 114 (not shown), and a bottom plate 115. The first side plates 111, second side plates 112, third side plates 113, and fourth side plates 114 are connected to the bottom plate 115. The third side plates 113 and fourth side plates 114 connect the first side plates 111 and second side plates 112. The first side plates 111, second side plates 112, third side plates 113, fourth side plates 114, and bottom plate 115 surround a receiving groove 210r. Different from the foregoing receiving groove 110r, the receiving groove 210r of this embodiment is, for example, in the shape of a cube or a cuboid. However, as long as it can carry the liquid leakage collecting member 120, form a channel, and form a receiving groove, the geometric structure of the receiving container is not limited in the embodiment of the present invention.

[0090] In summary, the embodiment of the present invention provides a receiving module, an inkjet head device using the same, and an inkjet printer. The receiving module can collect the liquid leakage of the printing liquid from the inkjet head, and can filter the liquid leakage to prevent the particles or dust of the liquid leakage from escaping and polluting the air, products (such as optical films), and / or equipment.

[0091] Of course, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
