Description

Technical Field

[0001] This invention relates to the field of inkjet printer technology, and more particularly to an inkjet printing apparatus and method for printing notebook packaging boxes. Background Technology

[0002] Packaging boxes are generally used to package items of various sizes, and their materials typically include paper and plastic. To better reflect the product information inside the box, various patterns and text are often displayed on the box surface, such as product specifications, brand information, and production information. For environmental reasons, notebook packaging often uses cardboard boxes. However, due to the large or numerous contents of notebook boxes, the internal cavity is relatively large, weakening the overall structural strength of the box and often resulting in uneven surfaces. This unevenness leads to poor print quality when printing information on the box surface, increasing the defect rate and impacting product production and packaging efficiency. Therefore, there is a need for an inkjet printing device and method for notebook packaging boxes that can effectively improve the inkjet printing effect on the surface of notebook packaging boxes. Summary of the Invention

[0062] This embodiment provides an inkjet printing device for notebook packaging boxes. Please refer to [link / reference]. Figures 1 to 19 The inkjet printing device for notebook packaging boxes includes: a carrier 2, a transport mechanism 100, a shaping mechanism 200, a pre-inspection mechanism 300, and a printing mechanism 400. The carrier 2 carries material 1. The transport mechanism 100 is arranged along the X-axis. The transport mechanism 100 carries the carrier 2 and drives the carrier 2 to move along the X-axis. The shaping mechanism 200 is located at the lifting position 123 of the transport mechanism 100. The shaping mechanism 200 includes a floating lifting device 210 and a shaping cover plate 221 connected to the transport mechanism 100. A receiving space is formed between the floating lifting device 210 and the shaping cover plate 221. The space is used to receive the carrier 2 carrying the material 1. The floating lifting device 210 can drive the carrier 2 to move the material 1 as a whole closer to the shaping cover plate 221 and can also drive the material 1 to partially adhere to the shaping cover plate 221. The shaping cover plate 221 has a first polygonal window 2214, through which the printing area of ​​the material 1 is exposed. The pre-inspection mechanism 300 is mounted above the transmission mechanism 100. The pre-inspection mechanism 300 is used to inspect the flatness of the printing area of ​​the material 1. The printing mechanism 400 is mounted above the transmission mechanism 100. The printing mechanism 400 is located downstream of the pre-inspection mechanism 300 along the X-axis. The printing mechanism 400 is used to perform inkjet printing and curing treatment on the printing area of ​​the material 1.

[0063] This disclosure provides an inkjet printing apparatus and method for notebook packaging boxes. A shaping mechanism 200 is used to flatten and shape the surface of material 1. The floating lifting device 210 and the shaping cover plate 221 of the shaping mechanism 200 cooperate to first fit the material 1 entirely onto the shaping cover plate 221, and then apply localized pressure to flatten the surface of material 1. A pre-inspection mechanism 300 further inspects the flatness of the printing area of ​​material 1 to ensure the flatness of the printing area of ​​material 1 printed by the printing mechanism 400.

[0064] In one feasible embodiment, the transmission mechanism 100 includes a linear module 110 and a first conveyor line 120 arranged along the X-axis. The linear module 110 is used to carry the first conveyor line 120 and reciprocate along the X-axis. The first conveyor line 120 is used to carry the carrier 2 and move unidirectionally along the X-axis. The lifting position 123 is disposed on the first conveyor line 120. The floating lifting device 210 and the shaping cover plate 221 are respectively fixedly connected to the first conveyor line 120.

[0065] In this way, by setting up the linear module 110 and the first conveyor line 120, the shaping mechanism 200 can be fixedly connected to the first conveyor line 120 to form a whole. The linear module 110 transports this whole, allowing the shaping mechanism 200 to move along with the carrier 2 and the material 1 to the pre-inspection mechanism 300 and then to the printing mechanism 400. The linear module 110 ensures the stability of the overall conveying operation, and the flexible conveying structure of the first conveyor line 120 can be connected to other conveyor lines. This effectively improves the structural stability of the transmission mechanism 100 and the operational stability of the notebook packaging box inkjet printing device, which is beneficial to improving the printing effect.

[0066] In one feasible implementation, the first conveyor line 120 includes a conveyor belt 121 and a conveyor printing bracket 410. The structure of the first conveyor belt can be a common conveyor belt structure, which will not be described in detail here.

[0067] In one feasible embodiment, the shaping cover plate 221 includes a frame portion 2211, the frame portion 2211 is provided with a first gradient groove forming a main body portion 2212, the main body portion 2212 is provided with a second gradient groove forming a printing portion 2213, and the polygonal window 2214 is disposed in the printing portion 2213.

[0068] In one feasible embodiment, the length L1 of the frame portion 2211 ranges from 400mm to 550mm, and the width W1 of the frame portion 2211 ranges from 300mm to 400mm. Optionally or preferably, the length L1 of the frame portion 2211 ranges from 480mm to 520mm, and the width W1 of the frame portion 2211 ranges from 320mm to 380mm. Optionally or preferably, the length L1 of the frame portion 2211 ranges from 500mm, and the width W1 of the frame portion 2211 ranges from 375mm. Such a length and width ratio can improve the overall strength of the shaping cover 221, and at the same time, it can accommodate various sizes of laptop packaging boxes, such as 13-inch, 14-inch, 15-inch, and 16-inch laptop packaging boxes.

[0069] In one feasible embodiment, the thickness T1 of the frame portion 2211 is 6mm to 10mm. Optionally or preferably, the thickness T1 of the frame portion 2211 is 7mm to 9mm. Optionally or preferably, the thickness T1 of the frame portion 2211 is 8mm. A frame portion 2211 of this thickness provides better support for the shaping cover plate 221, giving the shaping cover plate 221 better mechanical strength and facilitating the connection or installation of the shaping cover plate 221 with other components.

[0070] In one feasible embodiment, the length L2 of the main body 2212 ranges from 350mm to 450mm, and the width W2 of the main body 2212 ranges from 280mm to 320mm. Optionally or preferably, the length L2 of the main body 2212 ranges from 380mm to 420mm, and the width W2 of the main body 2212 ranges from 290mm to 310mm. Optionally or preferably, the length L2 of the main body 2212 ranges from 400mm, and the width W2 of the main body 2212 ranges from 300mm. In this way, the dimensional matching between the main body 2212 and the frame 2211 ensures both the structural strength of the shaping cover 221 and the mechanical strength of the printing section 2213, allowing the printing section 2213 to better fit the notebook packaging box and improve printing quality.

[0071] In one feasible embodiment, the thickness T2 of the main body 2212 ranges from 3mm to 4mm. Optionally or preferably, the thickness T2 of the main body 2212 ranges from 3mm to 3.5mm. Optionally or preferably, the thickness T2 of the main body 2212 ranges from 3.2mm. This dimensional fit between the main body 2212 and the frame 2211 ensures both the structural strength of the shaping cover 221 and the mechanical strength of the printing section 2213, allowing the printing section 2213 to better fit the notebook packaging box and improve printing quality.

[0072] In one feasible embodiment, the length L3 of the printing section 2213 ranges from 400mm to 550mm, and the width W3 of the printing section 2213 ranges from 150mm to 250mm. Optionally or preferably, the length L3 of the printing section 2213 ranges from 480mm to 520mm, and the width W3 of the printing section 2213 ranges from 190mm to 220mm. Optionally or preferably, the length L3 of the printing section 2213 ranges from 500mm, and the width W3 of the printing section 2213 ranges from 200mm.

[0073] In one feasible implementation, the thickness T3 of the printing portion 2213 ranges from 0.7mm to 1mm. Optionally or preferably, the thickness T3 of the printing portion 2213 ranges from 0.7mm to 0.9mm. Optionally or preferably, the thickness T3 of the printing portion 2213 ranges from 0.8mm. This gradually decreasing thickness allows the printing portion 2213 to be very thin, allowing it to fit as closely as possible to the surface of the notebook packaging box, while simultaneously maintaining mechanical strength to ensure proper adhesion to the surface of the notebook packaging box.

[0074] In one feasible implementation, the length L4 of the polygonal window 2214 ranges from 335mm to 360mm, and the width W4 of the polygonal window 2214 ranges from 130mm to 160mm. Optionally or preferably, the length L4 of the polygonal window 2214 ranges from 340mm to 350mm, and the width W4 of the polygonal window 2214 ranges from 135mm to 155mm. Optionally or preferably, the length L4 of the polygonal window 2214 ranges from 350mm, and the width W4 of the polygonal window 2214 ranges from 150mm. In this way, the polygonal window 2214 can better fit the notebook packaging box, making the printing area flatter and improving the printing effect.

[0075] In one feasible implementation, the polygonal window 2214 has a first window, a second window, and a third window with a rectangular cross-section. The second window is connected to the first long side of the first window, and the third window is connected to the first short side of the first window. The first short side is adjacent to the first long side, and the cross-sectional area of ​​the second window and the third window is smaller than the area of ​​the first window.

[0076] In one feasible implementation, the shaping cover 221 is a SUS440C metal component. SUS440C metal components are metal parts made of 440C steel. 440C steel is a martensitic stainless steel with a carbon content of 1.0% and a chromium content of 16-18%. It has strong rust resistance and is a high-quality stainless steel. Using SUS440C metal components for the shaping cover 221 provides excellent rust resistance, allowing it to withstand corrosion from printing solutions and extending its service life. Furthermore, using SUS440C metal components increases the cover's hardness and strength, enabling it to better conform to the surface of the notebook packaging box. When the notebook packaging box is a cardboard box, the SUS440C metal component covering the cardboard box can also apply pressure, making the area to be printed on the cardboard box flatter and achieving better printing results.

[0077] In one feasible implementation, the surface of the shaping cover plate 221 is treated with a matte finish. The matte finish avoids the reflection problem of the metal surface, improving the printing effect. Simultaneously, the matte-treated surface of the shaping cover plate 221 is more wear-resistant, less prone to scratches, and has a longer service life. The matte finish treatment of the shaping cover plate 221 can be achieved through the following methods: Chemical treatment: Chemical treatment involves applying acid or alkali impregnation to the stainless steel surface to change its microstructure, thereby producing a matte effect. Chemical treatment produces a relatively uniform matte finish with low surface roughness. Mechanical treatment: Mechanical treatment involves grinding, polishing, or other mechanical processing methods on the stainless steel surface to change its surface morphology, thereby producing a matte effect. Mechanical matte treatment can achieve a relatively uniform matte finish. Electrochemical treatment: Electrochemical treatment involves electrolytic processing on the stainless steel surface to change its surface morphology, thereby producing a matte effect. Electrochemical treatment produces a relatively uniform matte finish with controllable surface roughness.

[0078] In one feasible implementation, the frame portion 2211, the main body portion 2212, and the printing portion 2213 are integrally formed. The integrally formed shaping cover 221 can increase the overall strength and flatness of the shaping cover 221, allowing the shaping cover 221 to better fit the notebook packaging box and apply pressure to the notebook packaging box, thereby improving the printing effect.

[0079] In one feasible implementation, such as Figure 9As shown, the shaping mechanism 200 also includes a guide assembly 230. The guide assembly 230 is fixedly connected to the shaping cover plate 221 and is used to guide the material 1 closer to the shaping cover plate 221. The guide assembly 230 is arranged in pairs. It includes two sets of four guide wheels 231 and guide wheel connectors 232. The guide wheels 231 are also arranged in pairs and are located on both sides of the guide wheel connectors 232 along the width direction. When the floating lifting device 210 lifts the carrier 2 with the material 1, the outer edge of the guide wheel 231 fits against the outer edge of the material 1, so that the material 1 can more smoothly approach the shaping cover plate 221 along the Z-axis. Further, the shaping mechanism 200 also includes a shaping connecting plate 222, which is fixedly connected to the shaping cover plate 221. The guide assembly 230 is fixedly connected to the shaping cover plate 221 through the shaping connecting plate 222. The shaping connecting plate 222 is connected to the first conveyor line via the shaping connector 223. In this way, by setting the shaping connecting plate 222, the stability of the connection between the shaping mechanism 200 and the first conveyor line 120 can be improved.

[0080] like Figures 10-15 As shown, in one feasible embodiment, the floating lifting device 210 further includes: a lifting drive mechanism and at least two floating mechanisms, wherein each of the floating mechanisms includes a floating plate and a first connecting member, the floating plate is rotatably connected to the first connecting member, the first connecting member is connected to the output end of the drive mechanism, the lifting drive mechanism is used to drive the first connecting member to reciprocate along a third direction, the first connecting member drives the floating plate to reciprocate, and the floating plate is used to float and lift the material 1.

[0081] The floating lifting device 210 provided in this application embodiment is configured with at least two floating mechanisms 212. Each floating mechanism 212 has a floating plate 2121 that lifts the material 1, and each floating plate 2121 can rotate at a certain angle. In this way, the lifting of the material 1 by the floating plate 2121 is not only based on the lifting on a plane, but can fully fit the contact surface of the material 1 to achieve a better lifting effect.

[0082] In one feasible embodiment, the floating mechanism 212 further includes a rotating shaft 2123. The first connecting member 2122 has a first through hole along the first direction X, and the floating plate 2121 has a second through hole along the first direction X. The first through hole and the second through hole communicate to form a rotating shaft 2123 through hole, and the rotating shaft 2123 is disposed in the rotating shaft 2123 through hole. The floating plate 2121 also has a fifth through hole 21213, and the first connecting member 2122 passes through the fifth through hole 21213. In this way, a seesaw-like structure is formed, so that the floating plate 2121 rotates and swings around the rotating shaft 2123 as a fulcrum, so that the floating lifting device 210 can more flexibly conform to the surface of the component being processed.

[0083] In one feasible implementation, such as Figure 15 As shown, the floating plate 2121 and the first connecting member 2122 can also be connected in such a way that a rotatable connection can be achieved. Specifically, the floating plate 2121 and the first connecting member 2122 still have through holes for accommodating the rotating shaft 21323, but the first connecting member 2122 does not pass through the floating plate 2121. Instead, the first connecting member 2122 has a floating groove 213221 for accommodating the floating plate 2121, and the floating plate 2121 is disposed within the floating groove 213221. In this way, a rotatable connection between the floating plate and the connecting member can also be achieved.

[0084] In one feasible implementation, such as Figures 10-15 As shown, the floating mechanism 212 further includes a first substrate 2124 and a second substrate 2125. The first substrate 2124 is fixedly connected to the output end of the lifting drive mechanism 211. The lifting drive mechanism 211 drives the first substrate 2124 to move the second substrate 2125 along the third direction Z. The second substrate 2125 is disposed between the first substrate 2124 and the floating plate 2121. The first connecting member 2122 is fixedly connected to the second substrate 2125. The second substrate 2125 drives the floating plate 2121 to move along the third direction Z. The second substrate 2125 and the floating plate 2121 are parallel to each other. The first substrate 2124 can be used to support the carrier 2. The carrier 2 has a material 1 on it at the position corresponding to the floating plate 2121, and a through hole is partially opened at this position. The floating plate 2121 can pass through the through hole to contact the surface of the material 1, and fit against the surface of the material 1 according to the angle of the material 1 surface, and then lift the material 1.

[0085] In one feasible implementation, such as Figure 13As shown, the floating plate 2121 is also provided with a flexible gasket 21214, which is disposed at the part of the floating plate 2121 that contacts the material 1. Generally, the main body of the floating plate 2121 can be a metal part made of metal. When in contact with the processing component, it may cause wear or even damage to the processing component. The flexible gasket 21214 on the floating plate 2121 allows for flexible contact when the floating plate 2121 lifts the processing component, reducing the risk of damage to the processing component. The flexible gasket 21214 can be a silicone gasket or a rubber gasket, etc.

[0086] In one feasible implementation, the floating mechanism 212 further includes an anti-rotation component 2126. The original state plane of the floating plate 2121 is a first plane. The anti-rotation component 2126 is connected to the second base plate 2125 and the floating plate 2121 respectively to limit the angle of rotation of the floating plate 2121 based on the first plane. By setting the anti-rotation component 2126, the rotation angle of the floating plate 2121 can be limited to prevent excessive rotation.

[0087] In one feasible implementation, such as Figure 13 As shown, the anti-rotation assembly 2126 includes a first elastic element 21261. The first elastic element 21261 is connected to the second substrate 2125 and the floating plate 2121 respectively. The second substrate 2125 has a first limiting groove on the side facing the first elastic element 21261, and the floating plate 2121 has a second limiting groove on the side facing the first elastic element 21261. The two ends of the first elastic element 21261 abut against the first limiting groove and the second limiting groove respectively. When the floating plate 2121 is in its original state, the first elastic element 21261 is in a compressed state, thus playing an anti-rotation role and preventing the floating plate 2121 from rotating excessively.

[0088] In one feasible implementation, such as Figures 11-13 As shown, the floating lifting device 210 further includes a third base plate 213 and a first lifting guide mechanism 214. The third base plate 213 is fixedly connected to the lifting drive mechanism 211. The first lifting guide mechanism 214 is disposed between the third base plate 213 and the first base plate 2124. The first lifting guide mechanism 214 is used to guide the output end of the lifting drive mechanism 211 to lift the first base plate 2124.

[0089] In one feasible implementation, such as Figures 11-13As shown, the first lifting guide mechanism 214 includes a fourth base plate 2141, a first guide rod 2142, and a first guide rod bushing 2143. The first guide rod 2142 is arranged along the third direction Z. The fourth base plate 2141 is provided with a third through hole, and the first guide rod bushing 2143 is provided with a fourth through hole. The first guide rod bushing 2143 is fixed to the fourth base plate 2141, and the fourth through hole and the third through hole are connected to form a first guide rod through hole. One end of the first guide rod 2142 is sleeved in the first guide rod through hole, and the other end is fixed to the first base plate 2124.

[0090] In one feasible implementation, the lifting drive mechanism 211 includes a lifting cylinder, and the third substrate 213 and the fourth substrate 2141 have through holes. The piston rod of the lifting cylinder passes through the through holes of the third substrate 213 and the fourth substrate 2141 and is fixedly connected to the first substrate 2124.

[0091] In one feasible implementation, such as Figures 12-13 As shown, the floating mechanism 212 includes four second lifting guide mechanisms 2128. The four second lifting guide mechanisms 2128 are arranged along the second direction Y. Each second lifting guide mechanism 2128 is disposed between the first substrate 2124 and the second substrate 2125 connector, and is used to guide the first substrate 2124 to drive the second substrate 2125 to move along the third direction Z.

[0092] In one feasible implementation, such as Figures 12-13 As shown, the second lifting guide mechanism 2128 includes a second guide rod 21281 and a second guide rod bushing 21282. The second guide rod bushing 21282 is fixedly connected to the third base plate 213. The second guide rod 21281 is arranged along the third direction Z, with one end connected to the second base plate 2125 and the other end sleeved on the second guide rod bushing 21282.

[0093] In one feasible implementation, such as Figures 12-13 As shown, the floating mechanism 212 further includes a buffer component 2127; the buffer component 2127 is disposed between the first substrate 2124 and the second substrate 2125, and is used to buffer the potential energy of the first substrate 2124 driving the second substrate 2125 to move along the third direction Z.

[0094] In one feasible implementation, such as Figures 12-13As shown, the buffer assembly 2127 includes: two second elastic elements 21271, a geometric connector 21272, a U-shaped connector 21273, a pressure sensor 21274, and a pressure regulating assembly 11275. The two ends of the geometric connector 21272 are fixedly connected to the second guide rod sleeve 21282 of the second lifting guide mechanism 2128 on which the second elastic elements 21271 are sleeved. The outer side of the U-shaped top of the geometric connector 21272 abuts against the second base plate 21 25. The pressure sensor 21274 is fixed to the concave portion of the main body of the geometric connector 21272, and its sensing end contacts the inner side of the U-shaped top of the geometric connector 21272, used to measure the pressure of the second base plate 2125 on the geometric connector 21272. The second elastic elements 21271 are sleeved on the second guide rod 21281 along the third direction Z. One end of the second elastic element 21271 is connected to the second substrate 2125, and the other end is connected to the second guide rod sleeve 21282. The pressure adjustment assembly 21275 is used to adjust the distance between the two ends of the U-shaped connector 21273 and the corresponding second guide rod sleeve 21282, thereby adjusting the elastic state of the second elastic element 21271 according to the feedback result of the pressure sensor 21274.

[0095] In one feasible embodiment, the third substrate 213 is fixedly connected to the conveyor support 122 of the first conveyor line 120. The third substrate 213 is also fixedly connected to the output end of the linear module 110. The shaping connector 223 is fixedly connected to either the first positioning member 611 or the second positioning member 612 of the conveyor support 122. Thus, the third substrate floating lifting device 210, the shaping mechanism 200, and the first conveyor line 120 are all fixedly connected to the output end of the linear module 110.

[0096] In one feasible implementation, the carrier 2 is further provided with positioning pins and positioning holes, and the third base plate 213 of the floating lifting device 210 is provided with positioning holes corresponding to the pins and pins 2221 corresponding to the positioning holes. Thus, through the mutually cooperating positioning holes and pins, the floating lifting device 210 can precisely lift the carrier 2, improving lifting stability. Furthermore, the pins on the carrier 2 can be diagonally arranged, and similarly, the positioning holes can be arranged at another diagonal, while the positioning holes and pins on the first base plate are configured to cooperate, further improving the stability of the docking during lifting.

[0097] Furthermore, such as Figures 3-4 As shown, the linear module 110 is disposed on the first base plate 101, and a through groove is formed on the first base plate 101. The lifting drive mechanism of the floating lifting device 210 passes through the through groove and slides in the through groove along the X-axis direction under the drive of the linear module 110.

[0098] In one feasible implementation, an auxiliary slide rail assembly 102 is also provided on the first base plate 101. The third base plate of the floating lifting device 210 is connected to the linear module 110 and also to the auxiliary slide rail assembly 102. The auxiliary slide rail assembly 102 is used to assist the linear module 110 in driving the movement of the first transmission line and the shaping mechanism 200, thereby improving the stability of the operation of the notebook packaging box inkjet printing device.

[0099] In one feasible embodiment, the printing mechanism 400 includes: a printing bracket 410, a moving module 420, an inkjet assembly 430, and a curing assembly 450. The printing bracket 410 is disposed above the transport mechanism 100 along the Y-axis. The moving module 420 is disposed on the side of the printing bracket 410 along the X-axis near the pre-inspection mechanism 300, and is used to drive the inkjet assembly 430 to reciprocate along the Y-axis between the working position 401 and the waiting position 402 of the printing bracket 410. The inkjet assembly 430 is disposed at the moving end of the moving module 420 and is used to perform inkjet printing on the printing area of ​​the material 1. The curing assembly 450 is disposed on the side of the printing bracket 410 at the working position 401 along the X-axis away from the pre-inspection mechanism 300, and includes a UV lamp connected to the printing bracket 410, used to perform UV curing simultaneously with inkjet printing on the printing area of ​​the material 1.

[0100] By placing the inkjet assembly 430 and the curing assembly 450 on both sides of the print holder 410, the material 1 can be printed and cured simultaneously, improving printing efficiency.

[0101] Furthermore, during printing, the material 1 moves at a speed of 300 mm / s using the inkjet assembly 430, which achieves better printing results. At the same time, the inkjet assembly 430 and the curing assembly 450 can work well together.

[0102] In one feasible implementation, such as Figure 16 As shown, the waiting position 402 of the inkjet assembly 430 is also equipped with a scraper assembly 440. The scraper assembly 440 includes a scraper blade, an ink suction box, a waste liquid collection box, and a waste liquid bottle. Both the scraper blade and the ink suction box are housed in the waste liquid collection box. In this embodiment, two scraping methods are used: the scraper blade removes ink from the outside of the inkjet nozzle, and then the inkjet nozzle is inserted into the ink suction box to draw out the ink inside the nozzle, thus achieving complete cleaning of the inkjet nozzle. The cleaned ink is collected through the waste liquid collection box and flows into the waste liquid bottle. The scraper assembly 440 keeps the printhead moist when the inkjet assembly 430 is not in operation, preventing the printhead from drying out and maintaining a good printhead condition.

[0103] In one feasible implementation, such as Figure 4 and Figure 17 As shown, the first conveyor line 120 is also provided with an identification mechanism 600, which includes a first sensor assembly and a second sensor assembly. The first sensor assembly is used to detect the specifications of the material 1; the second sensor assembly is used to detect whether the material 1 is in place.

[0104] Further, in one feasible embodiment, the first sensor assembly includes a first detection unit 621 and a second detection unit 622. The detection direction of the first detection unit 621 is set along a second direction, and the detection direction of the second detection unit 622 is set along a first direction. The second direction and the first direction form an angle α in the plane containing the surface of the conveying bracket 122, and the angle α ranges from 0° to 90°. To better illustrate the automatic feeding and detection device for multi-specification materials 1 provided in this application embodiment, a laptop computer packaging box as a rectangular body is used as an example. A rectangular coordinate system is established with the width direction of the packaging box as the X-axis, the length direction of the packaging box as the Y-axis, and the thickness direction of the packaging box as the Z-axis. The second direction is the X-direction, hereinafter referred to as the second direction X. The plane containing the surface of the conveying bracket 122 is a plane perpendicular to the Z-axis. Optionally or preferably, the angle α ranges from 0° to 90°. Optionally or preferably, the angle α ranges from 45° to 90°. Optionally or preferably, the angle α ranges from 50° to 80°. Optionally or preferably, the included angle α ranges from 55° to 60°. Optionally or preferably, the included angle α ranges from 55.5°. The first sensor assembly is used to detect the specifications of material 1. Specifically, an included angle α is formed between the first detection unit 621 and the second detection unit 622, allowing the size specifications of material 1 to be detected from at least two angles. For example, from the length and width directions, or from the length and thickness directions, or from the width and height directions.

[0105] like Figure 1As shown, the conveying bracket 122 includes a first positioning member 611 and a second positioning member 612. The first positioning member 611 and the second positioning member 612 are arranged in pairs along the second direction, and their length direction is arranged along the fifth direction. The first positioning member 611 and the second positioning member 612 are used to install the detection mechanism. The fifth direction is the Y direction, hereinafter referred to as the fifth direction Y. The conveying bracket 122 also includes a carrier member, which is used to carry material 1 or a carrier 2 carrying material 1. The carrier member is a roller assembly, and the two ends of the roller assembly along the fifth direction are connected to the first positioning member 611 and the second positioning member 612. The roller assembly may include a roller shaft and a roller sleeved outside the roller shaft. The first positioning member 611 or the second positioning member 612 may be fixedly connected to the roller shaft or connected through other connecting members, which will not be described in detail here.

[0106] In one feasible implementation, the first detection unit 621 is disposed on a first plane, and the second detection unit 622 is disposed on a second plane, the first plane and the second plane being parallel to the plane containing the surface of the conveying bracket 122. Thus, the second detection unit 622 is used to detect the thickness of the material 1, while the first detection unit 621 can be used to detect the length or width angle of the material 1.

[0107] In one feasible implementation, the distance between the second plane along the second direction and the plane containing the surface of the conveying bracket 122 is a height H, where the second direction is perpendicular to both the first and second planes, and the height H ranges from 60.9 cm to 62.2 cm. This is based on the fact that the thickness of a thin notebook box is approximately 49 cm to 60.8 cm, and the thickness of a thick notebook box is 62.2 cm to 73 cm. When the material 1 of multiple specifications is a packaging box of the above specifications, the second detection unit 622 is configured to detect the height of the thick packaging box but not the height of the thin packaging box. Thus, when a signal is detected, it is a thick packaging box, and when no signal is detected, it is a thin packaging box.

[0108] In one feasible implementation, the first plane can also be higher than the plane where the bottom surface of the material 1 is located. Then, as long as the height of the second plane where the second detection unit 622 is located is higher than the thin material 1 but lower than the thick material 1, the thick material 1 can be detected but the thin material 1 cannot be detected.

[0109] In one feasible implementation, such as Figure 17As shown, the second sensor assembly includes a third detection unit 623 and a fourth detection unit 624. The detection direction of the third detection unit 623 is set along the second direction, and the detection direction of the fourth detection unit 624 is set along the fourth direction. The second direction and the fourth direction form an angle β in the plane containing the surface of the conveying bracket 122. The angle β ranges from 0° to 90°. Optionally or preferably, the angle β ranges from 0° to 45°. Optionally or preferably, the angle β ranges from 0° to 30°. Optionally or preferably, the angle β ranges from 0° to 10°. Optionally or preferably, the angle β ranges from 7.5°. Specifically, the third detection unit 623 and the fourth detection unit 624 form an angle α, which allows detection of whether the material 1 is in place from at least two angles. For example, detection can be performed from both ends of the length direction, or from both ends of the width direction.

[0110] In one feasible implementation, such as Figure 17 As shown, the distance between the first detection unit 621 and the third detection unit 623 along the fifth direction is length L. The fifth direction is perpendicular to the second direction in the plane containing the surface of the conveying bracket 122, and the length L ranges from 342cm to 368cm. This is based on the fact that the length of a 13- or 14-inch notebook packaging box is approximately 319cm to 341cm, and that of a 15- or 16-inch notebook packaging box is 368.5cm to 384.3cm. When the material 1 of multiple specifications is a packaging box of the above specifications, the first detection unit 621 and the third detection unit 623 are respectively located at both ends of the length direction of the packaging box. Thus, when the first detection unit 621 detects a signal but the third detection unit 623 does not, it indicates that the 13- or 14-inch laptop packaging box is not in place; when both the first detection unit 621 and the second detection unit 622 detect signals, it indicates that the 15- or 16-inch laptop packaging box is in place; when the first detection unit 621 does not detect a signal but the third detection unit 623 does, it indicates that the 13- or 14-inch laptop packaging box is in place. Thus, the first detection unit 621 detects the length specification on one side of the material 1's length direction; the third detection unit 623 detects whether the material 1 is in place on the other side of the material 1's length direction.

[0111] In one feasible implementation, the conveying support 122 is provided with a first limiting plate, which is used to limit the material 1 along the fifth direction. The length direction of the first limiting plate is set along the second direction, and the detection direction of the third detection unit 623 is set along the side of the first limiting plate close to the material 1.

[0112] In one feasible implementation, such as Figure 17As shown, the conveying support 122 is provided with a second limiting member, and the carrier 2 used to carry the material 1 is provided with a first limiting member. The second limiting member is used to limit the carrier 2. When the carrier 2 is in the position limited by the second limiting member, the third detection unit 623 is set to detect the material 1 in the length direction on one side, and is used to detect whether the material 1 is in place.

[0113] In one feasible implementation, such as Figure 17 As shown, the fourth detection unit 624 includes two fourth through-beam sensors arranged in pairs, which are respectively disposed on the first positioning member 611 and the second positioning member 612. The fourth detection unit 624 is aligned with the first positioning member 611, and its detection direction can penetrate a corner along the thickness direction of the 13- or 14-inch laptop packaging box. Thus, when the fourth detection unit 624 can detect the model number through the through-beam sensor, the 13- or 14-inch laptop packaging box is not misaligned.

[0114] In one feasible implementation, the first detection unit 621, the second detection unit 622, the third detection unit 623, and the fourth detection unit 624 are through-beam sensors, with the transmitter and receiver of the through-beam sensor respectively fixed to the first fixing member and the second fixing member. Through-beam sensors have high accuracy, fast response speed, high reliability, and stable accuracy, making them very suitable for applications requiring high-speed response, such as automated production lines and robots, and thus facilitating their widespread application.

[0115] In one feasible implementation, the first detection unit 621, the second detection unit 622, the third detection unit 623, and the fourth detection unit 624 can also be laser sensors. In this way, the above detection units do not need to be set in pairs, but only need to be set on one side of the packaging box. By detecting the distance between them and the packaging box, the system can determine whether the device is in place or its size. Further details will not be provided here.

[0116] Accordingly, this application also provides a multi-specification material 1 information printing system. This multi-specification material 1 information printing system includes the aforementioned multi-specification material 1 automatic feeding and detection device. The multi-specification material 1 information printing system also includes a printing device connected to the multi-specification material 1 automatic feeding and detection device. The printing device performs an information printing operation on the material 1 based on the information about the material 1 detected by the multi-specification material 1 automatic feeding and detection device.

[0117] In one feasible implementation, the multi-specification material 1 information printing system is used to print information on 13-inch / 14-inch thin notebook packaging boxes, 13-inch / 14-inch thick notebook packaging boxes, 15-inch / 16-inch thin notebook packaging boxes, and 15-inch / 16-inch thick notebook packaging boxes. The dimensions of the 13-inch, 14-inch, 15-inch, and 16-inch thick and thin notebooks are shown in Table 1.

[0118] Table 1: Dimensions of Various Paper Box Specifications

[0119]

[0120] Please refer to Figure 17 The first detection unit 621 includes two paired first through-beam sensors, the second detection unit 622 includes two paired second through-beam sensors, the third detection unit 623 includes two paired third through-beam sensors, and the fourth detection unit 624 includes two paired fourth through-beam sensors. The paired through-beam sensors are respectively fixed to the first positioning member 611 and the second positioning member 612. The distance between the first detection unit 621 and the third detection unit 623 on the first positioning member 611 and the second positioning member 612 is 320cm, and the height distance of the second detection unit 622 from the bottom surface of the cardboard box is 62cm. The distance between the fourth detection unit 624 and the third detection unit 623 on the first positioning member 611 is 35.25cm, and the distance between the fourth detection unit 624 and the third detection unit 623 on the second positioning member 612 is 31.35cm. The system records a 1 for when the through-beam sensor receives a signal and a 0 for when it does not. Based on the signal collection from the four detection units, the printing device can determine the status of the paper tray, whether to print information, and what specifications of information to print. Printing only proceeds if the result is OK, and the printing information is determined based on the results of the four detection units. If the result is NG, printing does not proceed, the paper is reloaded, and the above determination is repeated. Specific determination results are shown in Table 2.

[0121] Table 2: Signals and Judgment Results

[0122]

[0123] In one feasible implementation, such as Figure 18 As shown, the pre-inspection mechanism 300 includes an inspection bracket 310 and a CCD image sensor assembly 320 and at least three point laser sensor assemblies 330 disposed on the inspection bracket 310. The CCD image sensor assembly 320 is used to detect the center position of the printing area, and the three point laser sensor assemblies 330 are used to detect the flatness of the printing area.

[0124] Furthermore, the CCD image sensor assembly captures images of the packaging box's edges, specifically the upper left and lower right corners of the printing area, to calculate the center position of the box. Three laser sensors, in conjunction with a strip light source, detect the flatness of the printing area.

[0125] In one feasible implementation, such as Figure 19As shown, the inkjet printing device for the notebook packaging box also includes a re-inspection mechanism 500. The re-inspection mechanism 500 is located downstream of the printing mechanism 400 along the X-axis. The re-inspection mechanism 500 includes a second base plate 501 and a second conveyor line 510 disposed on the second base plate 501, a re-inspection lifting device 520, a re-inspection cover plate 530, and a re-inspection module 540. The second conveyor line connects to the rear end of the first conveyor line 120 along the X-axis, serving to support the carrier 2 and drive the carrier 2 to move along the X-axis. A receiving space is formed between the re-inspection lifting device 520 and the re-inspection cover plate 530. This space is used to accommodate the carrier 2 carrying the material 1. The re-inspection lifting device 520 can drive the carrier 2 to move the material 1 as a whole closer to the re-inspection cover plate 530. The re-inspection cover plate 530 has a second polygonal window 2214, through which the printing area of ​​the material 1 is exposed. The re-inspection module 540 is mounted above the re-inspection lifting device 520 and is used to detect the printing status of the material 1. By setting up the re-inspection mechanism 500, the printing effect of the printed notebook packaging box can be inspected, which facilitates the execution of subsequent processes. Among them, the re-inspection lifting device 520 and the re-inspection cover plate 530 in the re-inspection mechanism 500 are similar to the shaping mechanism 200, the second conveyor line 510 is similar in structure to the first conveyor line 120, and the re-inspection module 540 is similar in structure to the pre-inspection module, which will not be described in detail here.

[0126] In one feasible implementation, such as Figures 1-2 As shown, the transmission mechanism 100 further includes a third conveyor line 130 arranged along the X-axis. The third conveyor line 130 is arranged along the Z-axis below the first conveyor line 120 and the second conveyor line 510. The front end of the third conveyor line 130 is connected to the rear end of the second conveyor line 510, and the rear end of the third conveyor line 130 is connected to the front end of the first conveyor line 120. The structure of the third conveyor line 130 is similar to that of the first conveyor line 120, and will not be described in detail here. By setting the third conveyor line 130, the empty carrier 2 can be retrieved in a timely manner. At the same time, the double-layer structure design of the third conveyor line 130, the first conveyor line 120, and the second conveyor line 510 can effectively save space, simplify the structure of the inkjet printing device for notebook packaging boxes, and improve space utilization.

[0127] This embodiment also provides a method for inkjet printing of notebook packaging boxes, which is implemented based on the inkjet printing device for notebook packaging boxes provided in the above embodiment. The inkjet printing method for notebook packaging boxes includes the following steps:

[0128] The carrier 2, fully loaded with material 1, flows into the first conveyor line 120 of the conveying mechanism 100;

[0129] The first conveyor line 120 conveys the carrier 2 along the X-axis to the shaping mechanism 200 of the lifting position 123 provided on the first conveyor line 120;

[0130] After the floating lifting device 210 of the shaping mechanism 200 drives the carrier 2 away from the first conveyor line 120 and brings the material 1 as a whole close to the shaping cover plate 221, the floating mechanism of the floating lifting device 210 then drives the printing area surface of the material 1 to be flat.

[0131] The linear module 110 of the transmission mechanism 100 drives the first conveyor line 120, the carrier 2, and the shaping mechanism 200 to move along the X-axis to below the pre-inspection mechanism 300.

[0132] The CCD image sensor assembly 320 of the pre-inspection mechanism 300 detects the center position of the printing area, and the dot laser sensor assembly 330 of the pre-inspection mechanism 300 detects the flatness of the printing area.

[0133] The moving module 420 of the printing mechanism 400 moves the inkjet assembly 430 from the waiting position 402 to the working position 401 along the Y-axis;

[0134] The linear module drives the first conveyor line 120, which has completed the pre-inspection, as well as the carrier 2 and the shaping mechanism 200, to move in the opposite direction along the X-axis below the working position 401 of the printing mechanism 400;

[0135] The linear module drives the first conveyor line 120, which has completed the pre-inspection, as well as the carrier 2 and the shaping mechanism 200 to move uniformly in the opposite direction along the X-axis.

[0136] The inkjet assembly 430 prints on the printing area, while the curing assembly 450 of the printing mechanism 400 performs UV curing on the printing area.

[0137] The linear module drives the first conveyor line 120, the carrier 2, and the shaping mechanism 200 to move in the opposite direction along the X-axis to complete the printing and curing process.

[0138] Furthermore, the inkjet printing method for notebook packaging boxes may also include the following steps after completing the above steps:

[0139] The floating lifting device 210 of the shaping mechanism 200 descends, and the carrier 2 falls onto the first conveyor belt;

[0140] The carrier 2 is transported from the first conveyor belt to the second conveyor belt 121 of the re-inspection mechanism 500;

[0141] The re-inspection unit 500 re-inspects the printing area of ​​material 1;

[0142] The second conveyor belt 121 continues to transport vehicle 2 out of the second conveyor belt 121;

[0143] The printed material 1 is removed from carrier 2, and the empty carrier 2 flows into the third conveyor line 130 and returns through the third conveyor line 130.

[0144] The inkjet printing device and method for notebook packaging boxes provided in this application flatten and shape the surface of the material by setting up a shaping mechanism. The floating lifting device and shaping cover of the shaping mechanism work together to first fit the material as a whole against the shaping cover, and then apply pressure locally to make the material surface flat. A pre-inspection mechanism checks the flatness of the printing area of ​​the material to further ensure the flatness of the printing area of ​​the material printed by the printing mechanism. By setting up a linear module and a first conveyor line, the shaping mechanism and the first conveyor line can be fixedly connected to form a whole, and the linear module transports this whole. This allows the shaping mechanism to move with the carrier and the material to the pre-inspection mechanism and then to the printing mechanism. The linear module can ensure the stability of the overall conveying operation, and the conveying structure of the first conveyor line is flexible and can be docked with other conveyor lines. In this way, the structural stability of the transmission mechanism is effectively improved, as is the operational stability of the inkjet printing device for notebook packaging boxes, which is conducive to improving the printing effect.
