Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0029] like Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, a feeding system 100 of a graphic device is provided, and the graphic device is suitable for inkjet hot melt printing at a printing station. The feeding system 100 of the graphic device includes a feeding buffer area 110, a cooling device 120 and a main conveyor line 101. The feeding buffer area 110 is provided with a plurality of feeding sub-stations; the cooling device 120 is arranged in the feeding buffer area 110, and the cooling device 120 is suitable for cooling the feeding buffer area 110; the main conveyor line 101 is suitable for conveying a substrate 102 upstream of the feeding buffer area 110, so that a plurality of feeding sub-stations alternately cache the substrate 102, and the substrate 102 that has completed cooling at the feeding sub-station is fed to the printing station.

[0030] In this embodiment, the substrate 102 is a battery cell.

[0031] The graphic equipment performs hot melt inkjet printing at the printing station. Hot melt inkjet printing uses hot melt materials as printing materials. The printing materials are solid before use. When used, they are melted into liquid by heat energy in the inkjet unit, and then sprayed onto the surface of the solar cell to condense and solidify to form a patterned mask. The printing materials usually selected have a viscosity of 0.1mPa-s to 20mPa-s when the temperature is greater than 50°C, and a viscosity greater than or equal to 10000mPa-s or solid when the temperature is less than 25°C, such as one or more of acrylic acid, rosin ester resin, C11-C22 alkyl acid, polypropylene wax, microcrystalline wax, polyethylene wax, and ethylene vinyl acetate copolymer wax. In the hot melt inkjet printing process, the solidification rate of the printed ink droplets on the surface of the solar cell at room temperature is low, which means that on the one hand, the ink droplets solidify for a long time on the surface of the cell at room temperature, which will prolong the residence time of the cell in the printing process and affect the production efficiency. On the other hand, the long spreading time of the ink droplets on the surface of the cell will affect the morphology of the ink droplets and thus affect the molding quality of the pattern film mask.

[0032] If the cooling device 120 is directly set in the printing process, it is difficult for the room temperature of the battery cells to be quickly reduced to the ideal temperature within the printing time, and the battery cells still need to stay in the printing process, and the production efficiency is still low. If the cooling device 120 is directly set on the loading and conveying line, in order to reduce the surface temperature of the battery cells entering the printing station to the ideal temperature in advance, this means that the loading and conveying line and the cooling device 120 must be set particularly long, which will not only greatly increase the length and floor space of the equipment, but also increase the loading and conveying time, which will still affect the overall production efficiency.

[0033] The present application ingeniously designs a feeding system suitable for hot melt inkjet printing technology, which utilizes the cooperation of the feeding buffer area 110, the cooling device 120 and the main conveying line 101 to reduce the surface temperature of the substrate 102 entering the printing station to an ideal temperature while ensuring the feeding and conveying efficiency, thereby allowing the ink droplets of hot melt inkjet printing to quickly condense and solidify on the surface of the substrate 102, which is conducive to reducing the solidification time of the ink droplets on the surface of the substrate 102 and improving the shape retention of the ink droplets on the surface of the substrate 102, thereby improving the production efficiency of the printing process and the molding quality of the pattern film mask. In addition, the feeding system of the present application can also improve the safety of the printing station when an error occurs and the shutdown occurs.

[0034] Among them, a cooling device 120 and a plurality of feeding sub-stations are arranged in the feeding buffer area 110. The cooling device 120 is arranged in the feeding buffer area 110. The cooling device 120 can reduce the surface temperature of the substrate 102 cached in the feeding buffer area 110, so that the surface temperature of the substrate 102 meets the printing requirements. When the substrate 102 cached in one of the feeding sub-stations is cooling down, the substrate 102 in another feeding sub-station has already finished cooling down. The substrate 102 in the feeding sub-station that has finished cooling down can be fed to the printing station. After the feeding is completed, the feeding sub-station that was previously cooling down has finished cooling down, so that the feeding can start. Therefore, the plurality of feeding sub-stations can alternately feed, so that the substrate 102 that has finished cooling down can be continuously fed to the printing station by the main conveyor line 101, thereby improving the feeding efficiency.

[0035] The loading buffer area 110 can cool down the cooled substrate 102 in one line and continuously load the cooled substrate 102 in one line, which can improve the safety when the printing station stops due to an error and improve the loading efficiency; a cooling device 120 is set in the loading buffer area 110 to improve the production efficiency of the whole machine and can improve the printing quality of the substrate 102 at the printing station.

[0036] In another embodiment, a lifting and translating mechanism 140 is provided between the feeding branch line 112 and the main conveying line 101 , and the lifting and translating mechanism 140 is suitable for translating the substrate 102 on the main conveying line 101 to the feeding branch line 112 .

[0037] The equipment starts preheating and begins printing. At this time, the first loading station 1101 supplies materials to the printing station through the first buffer device 113. At the same time, the incoming materials from the main conveyor line 101 enter the loading branch line 112, and then enter the second loading station 1102 for buffering.

[0038] In this embodiment, the lifting and translation mechanism 140 can translate the substrates 102 on the main conveying line 101 to the feeding branch line 112 , so as to realize the diversion of the substrates 102 on the main conveying line 101 .

[0039] Both the feeding branch line 112 and the main conveying line 101 are provided with a regularization mechanism 150 , so that the position of the substrate 102 can be adjusted before entering the feeding buffer area 110 .

[0040] In another embodiment, continue to combine Figure 3 As shown, the feeding system 100 of the graphic device also includes a feeding bin 111 and at least one feeding branch line 112. The feeding branch line 112 is arranged in parallel with the main conveyor line 101, and the feeding bin 111 is provided for the main conveyor line 101 and the feeding branch line 112 to pass through; wherein, the feeding buffer area 110 is arranged in the feeding bin 111, and the plurality of feeding sub-stations include a first feeding sub-station 1101 and a second feeding sub-station 1102. The first feeding sub-station 1101 is located on the main conveyor line 101 in the feeding bin 111, and the second feeding sub-station 1102 is located on the feeding branch line 112 in the feeding bin 111.

[0041] In this embodiment, the feeding branch line 112 also includes one or more conveying units 103 .

[0042] The feeding branch line 112 can be set as one, so that the feeding branch line 112 and the main conveying line 101 arranged side by side can form a feeding buffer area 110. The main conveying line 101 is provided with a first feeding sub-station 1101, and the feeding branch line 112 is provided with a second feeding sub-station 1102. The first feeding sub-station 1101 and the second feeding sub-station 1102 are arranged in the feeding bin 111, and the feeding bin 111 can be made into a relatively closed empty shell, which is conducive to the cooling device 120 to cool the feeding buffer area 110 in the feeding bin 111, saving energy.

[0043] In another embodiment, continue to combine Figure 3 As shown, the loading branch line 112 includes: a first loading line 1121, a second loading line 1122 and a unloading line 1123, the first loading line 1121 is arranged at an angle to the main conveying line 101, the second loading line 1122 is arranged at an angle to the first loading line 1121, the second loading line 1122 is provided with a second loading sub-station 1102 and a second buffer device 114, the second loading line 1122 and the main conveying line 101 are spaced apart from each other and arranged side by side, the unloading line 1123 is arranged at an angle to the second loading line 1122 and the main conveying line 101, so that the substrate 102 on the second loading line 1122 enters the main conveying line 101 through the unloading line 1123; wherein, the second loading line 1122 runs through the loading bin 111.

[0044] In this embodiment, the first loading line 1121 is arranged perpendicularly to the main conveying line 101, the second loading line 1122 is arranged parallel to the main conveying line 101, and the unloading line 1123 is arranged perpendicularly to the main conveying line 101. The first loading line 1121 and the unloading line 1123 are both located outside the loading bin 111. The loading bin 111 is provided with two openings on opposite sides of the conveying direction of the main conveying line 101 for the main conveying line 101 to pass through. Two openings are provided on opposite sides of the conveying direction of the second loading line 1122 for the second loading line 1122 to pass through.

[0045] If the substrate 102 enters the loading bin 111 through the main conveyor line 101, the substrate 102 enters the first loading sub-station 1101 for buffering and then loading. If the substrate 102 enters the loading bin 111 through the first loading line 1121 and the second loading line 1122, the substrate 102 enters the second loading sub-station 1102 for buffering and then returns to the main conveyor line 101 through the unloading line 1123 for loading.

[0046] In another embodiment, the cooling device 120 includes a non-contact cooling structure, such as an air cooling system. The air cooling system cools the loading buffer area 110 by air cooling, thereby achieving non-contact cooling of the substrate 102.

[0047] If the temperature of the loading buffer area 110 does not meet the requirements, the cooling device 120 is turned on to cool the loading buffer area 110. The cooling is stopped until the temperature of the loading buffer area 110 meets the requirements. The cooling device 120 may be an air cooling system.

[0048] The cooling system of the cooling device 120 can be made into a fully enclosed form, leaving only the conveying inlet and the conveying outlet with a size similar to that of the substrate 102, and filling the relatively closed environment with circulating cooling air to cool the substrate 102. The cooling device 120 is arranged in the feeding system 100 of the graphic device, which reduces the cooling time of the substrate 102 at the printing station and improves the printing speed.

[0049] In this embodiment, during the startup preheating work of the graphic device 10, the substrate 102 on the main conveyor line 101 enters the first loading substation 1101 for buffering. The substrate 102 entering the first loading substation 1101 is cooled in the closed loading bin 111 at the same time, so that the substrate 102 can obtain a qualified surface temperature. The first loading substation 1101 that has completed the cooling can start loading. At the same time, the substrate 102 enters the second loading substation 1102 for buffering and cooling at the same time. After the cooling is completed, the loading mode is turned on.

[0050] In another embodiment, the loading system 100 of the patterning device further includes a photoluminescence detection device 130 . The photoluminescence detection device 130 is located on the main conveying line 101 , and the photoluminescence detection device 130 is located downstream of the loading buffer area 110 .

[0051] In this embodiment, a waste removal mechanism 160 and a rotary feeding mechanism 170 are provided in sequence downstream of the photoluminescence detection device 130. The substrate 102 is transmitted to the photoluminescence (PL) detection device 130 for stopping. The photoluminescence detection device 130 is arranged upstream of the printing station of the main conveying line 101, so that the substrate 102 entering the main conveying line 101 from the loading buffer area 110 can be transported to the PL detection device for hidden crack detection, and the hidden cracked substrate will be discharged through the waste removal mechanism 160. The waste removal mechanism 160 is a lifting and translation mechanism. The waste removal mechanism 160 removes unqualified substrates 102 to the NG material box buffer, thereby ensuring that the substrates 102 entering the printing station through the rotary feeding mechanism 170 are all qualified. The rotary feeding mechanism 170 can feed the qualified substrates 102 to the printing station.

[0052] The first PL detection device performs optical detection on the quality of the substrate 102 to test the abnormalities of the substrate 102, including scratches and foreign matter other than hidden cracks. If OK, it will continue to be transported to the carrying unit 230. If NG, it will be transported to the waste film recovery device on the side.

[0053] In another embodiment, each loading sub-station is provided with at least one buffer device to sequentially buffer the substrates 102 entering the corresponding loading sub-station.

[0054] In this embodiment, the first loading substation 1101 is provided with a first buffer device 113, and the second loading substation 1102 is provided with a second buffer device 114, and the buffer device is a material lifting basket. The first buffer device 113 and the second buffer device 114 are respectively provided with two, and the two first buffer devices 113 are sequentially arranged along the feeding direction of the main conveyor line 101, and the two second buffer devices 114 are sequentially arranged along the feeding direction of the feeding branch line 112. Uninterrupted feeding can be ensured, and the feeding rhythm is guaranteed.

[0055] After the substrate 102 cached by the first loading station 1101 is loaded, the substrate 102 cached by the second loading station 1102 is completed. At this time, the second loading station 1102 starts to load the printing station, and the first loading station 1101 starts the cache mode. In this way, the first loading station 1101 and the second loading station 1102 alternately load the printing station.

[0056] In another embodiment, Figure 3As shown, the main conveying line 101 includes a plurality of conveying units 103 , and the plurality of conveying units 103 are arranged in sequence in the conveying direction of the main conveying line 101 .

[0057] The above-mentioned main conveyor line 101 is a single conveyor line. The main conveyor line 101 includes a plurality of conveyor units 103, which are sequentially arranged in the conveying direction of the main conveyor line 101. Each conveyor unit 103 includes a base 1031, a belt frame 1032, a motor 1033, a driving pulley 1035, a driven pulley 1036, a pulley shaft 1034, a transmission belt 1037 and a conveyor belt 1038. The base 1031 is used to support two belt frames 1032, and the two belt frames 1032 are arranged at intervals from each other, and the two belt frames 1032 can be parallel to each other. A conveyor belt 1038 is wound around each belt frame 1032. A connecting block is connected to the end of each belt frame 1032, one end of the pulley shaft 1034 is rotatably connected to a connecting block, and the other end of the pulley shaft 1034 is rotatably connected to another connecting block. The driving pulley 1035 and the passive pulley 1036 are both arranged on the pulley shaft 1034, and the conveyor belt 1038 is arranged on the passive pulley 1036 on the corresponding side. The pulley shaft 1034 is provided with a driving pulley 1035, and the motor 1033 drives the driving pulley 1035 to rotate through the transmission belt 1037, so that the pulley shaft 1034 rotates, thereby rotating the passive pulley 1036, and the passive pulley 1036 drives the corresponding conveyor belt 1038 to rotate. When the substrate 102 is placed on the two conveyor belts 1038, the two conveyor belts 1038 rotate to transport the substrate 102.

[0058] The present application also proposes a graphic device, which includes a printing device 200 and a loading system 100 of any graphic device. The printing device 200 is arranged at a printing station. The printing device 200 is suitable for hot melt inkjet printing on a substrate 102. The printing device 200 includes a carrying unit and an inkjet unit. The carrying unit is suitable for carrying the substrate, and the inkjet unit is suitable for spraying liquid hot melt ink droplets onto the substrate.

[0059] The patterning device 10 in this embodiment is mainly used for loading materials before manufacturing mask layers in photovoltaics and semiconductors.

[0060] The main patterning process methods in the photovoltaic and semiconductor fields have certain shortcomings. The single-line material loading has unstable supply quantity and the battery cell incoming rhythm before printing is unstable, which affects the overall rhythm of the printing equipment.

[0061] There is also the problem of hidden cracked cells. If hidden cracked cells are mixed in the feeding process, the yield rate of the whole machine will be affected. PL detection is performed before feeding the printing machine to remove hidden cracked cells, which increases the yield rate of the printing. Therefore, by setting up the photoluminescence detection device 130 and the waste removal mechanism 160, the problem of hidden cracked cells can be solved.

[0062] The present application adopts the method of adding a material loading buffer area 110 to the conveyor line, wherein the material loading buffer area 110 is provided with a first material loading station 1101 and a second material loading station 1102, and the first material loading station 1101 and the second material loading station 1102 are respectively provided with two buffer devices. The first material loading station 1101 and the second material loading station 1102 share a chamber. The first material loading station 1101 and the second material loading station 1102 alternately feed materials to the printing station, thereby reducing the unstable material rhythm and improving the output of the whole machine.

[0063] like Figure 4 and Figure 5 As shown, according to an embodiment of the present invention, a feeding method of a feeding system 100 of a patterning device is also provided. The feeding system 100 of any one of the patterning devices is adopted, and the feeding method of the feeding system 100 of the patterning device comprises the following steps:

[0064] Step S101: conveying a substrate 102 into a plurality of loading stations of a patterning device for buffering;

[0065] Step S103: Cooling down the substrate 102 buffered in the loading station;

[0066] Step S105: Control the substrate 102 of the loading sub-station that has completed cooling to load the printing station.

[0067] Step S107: Control the substrate 102 to be transported to the printing station to complete inkjet printing;

[0068] In the present embodiment, when one of the loading sub-stations is caching the substrate 102, the substrate 102 of another loading sub-station has completed caching, and the substrate 102 of the loading sub-station that has completed caching can be loaded to the printing station; after loading is completed, the loading sub-station that was previously caching has completed caching and can start loading. Therefore, multiple loading sub-stations can load alternately, so that the substrate 102 can be continuously fed into the printing station by the main conveyor line 101, thereby improving the loading efficiency, and thereby improving the overall work efficiency of the graphics device 10.

[0069] When the substrate 102 buffered in one loading sub-station is cooling down, the substrate 102 in another loading sub-station has already finished cooling down, and the substrate 102 in the loading sub-station that has finished cooling down can be loaded to the printing station; after loading, the loading sub-station that was previously cooling down has finished cooling down, and can start loading, so multiple loading sub-stations can load alternately, so that the substrates 102 that have finished cooling down can be continuously fed to the printing station by the main conveyor line 101. Compared with setting the cooling device 120 at the printing station, setting the cooling device 120 in the loading buffer area 110 saves the cooling time and improves the loading work efficiency.

[0070] Obviously, the above embodiments are merely examples for clear description and are not limitations of the implementation methods.

[0071] For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the protection scope of the invention of the utility model.
