Considering the production efficiency, it is urgent to develop a patterning equipment feeding device suitable for hot melt inkjet printing.

[0005] In the first aspect, the utility model provides a patterning equipment feeding device, which comprises:

[0006] The feeding conveying line is used for conveying the substrate to the pattern printing station.

[0007] The turnover mechanism is arranged in series on the feeding conveying line, and a plurality of turnover stations are arranged on the turnover mechanism.

[0009] Beneficial effects: The turnover mechanism and the cooling mechanism are arranged on the feeding conveying line. The turnover mechanism can not only turn the substrate, but also make the substrate stay on the turnover mechanism for a period of time during the turning. The cooling mechanism cools the turnover mechanism and the ambient temperature of the turnover mechanism to a preset temperature. The substrate is cooled by the cooling mechanism immediately after being received by the turnover mechanism, and is cooled to the preset temperature by the cooling mechanism within a preset time after being turned to the downstream feeding conveying line of the turnover mechanism, and then is output to the printing position of the substrate by the downstream feeding conveying line of the turnover mechanism. The printing position of the substrate surface is printed by the printing position of the substrate surface. The preset temperature makes the mask of the printing position cool quickly, and the mask layer on the substrate surface solidifies rapidly and sufficiently, which is beneficial to shorten the solidification time of the mask layer on the substrate surface, thereby improving the production efficiency, and is beneficial to improve the quality of the mask pattern. At the same time, it is beneficial to prevent the local temperature rise of the substrate in contact with the turnover mechanism, and ensure the integrity of the mask pattern on the substrate.

The clamping groove clamps the substrate, and after the rotating member group synchronously rotates, the substrate clamped in the clamping groove can be turned over, the structure is simple, and the turning over is easy to realize.

[0018] In an optional embodiment, the inner side of the rotating member is provided with a support member one-to-one corresponding;

[0019] The support member is provided with a support groove corresponding to the clamping groove, and the support groove and the clamping groove form the turnover station.

[0022] The support groove extends in the radial direction of the support member, and the support groove is open in a direction away from the center.

[0023] In an optional embodiment, the cooling mechanism comprises:

[0024] A housing is arranged outside the turnover mechanism;

[0032] Beneficial effects: The patterning device of the present application integrates the flipping and cooling in the same station of the upper conveying line. The upper conveying line and the lower conveying line are parallel to each other and have opposite conveying directions; both are perpendicular to the direction in which the printing mechanism transports the substrate.

For a square substrate, the linear material moving assembly between the upper conveying line and the printing mechanism can directly move the substrate on the upper conveying line to the printing mechanism without changing the direction. Similarly, the linear material moving assembly between the printing mechanism and the lower conveying line can move the substrate on which the inkjet printing is completed to the lower conveying line without changing the direction. In the above material moving process, the substrate does not need to be deflected by 90° in the plane, and does not need to be adjusted in length and width. The cost of using the linear material moving assembly is lower.

[0037] In an alternative embodiment, the upper conveying line and the lower conveying line each include a plurality of parallel conveying belts for conveying a plurality of substrates at the same time.

[0041] Beneficial effects: The feeding conveying line and the discharging conveying line are arranged in parallel and in opposite directions, and the transmission directions of the two printing stations on the printing mechanism are perpendicular to the above two directions. For rectangular substrates, since the rectangular substrates are different in length and width, and the positions of the substrates need to be exchanged when the substrates are transferred from the feeding conveying line to the printing mechanism and from the printing mechanism to the discharging conveying line, the rotating material moving assembly between the feeding conveying line and the printing mechanism sucks up two rectangular substrates on the feeding conveying line and moves them to the printing mechanism, and the two rectangular substrates need to be deflected by 90° in the planar direction to change their relative positions, so as to match the two printing stations on the printing mechanism. The conveying direction of the feeding conveying line is the first direction, and the second direction is perpendicular to the first direction in the horizontal plane. The transmission direction of the substrates on the printing stations is the second direction, and the two printing stations are arranged along the first direction. The two substrates on the different conveying belts on the feeding conveying line are arranged in sequence in the second direction, and when they are moved to the printing mechanism by the rotating material moving assembly, they are arranged in sequence along the first direction. Similarly, the rotating material moving assembly between the printing mechanism and the discharging conveying line can move the substrates on which the inkjet printing is completed from the printing mechanism to the discharging conveying line. The two rectangular substrates on which the inkjet printing is completed are sucked up and moved to the discharging conveying line, and the two rectangular substrates need to be deflected by 90° in the planar direction to change their relative positions, so as to match the two conveying belts on the discharging conveying line. At this time, the entire conveying line during multi-station printing is designed in a U shape. The use of multiple conveying belts and the rotating material moving assembly to convey the substrates to the corresponding multi-stations on the printing mechanism can increase the printing efficiency, save space and structural cost as much as possible, and improve the equipment productivity and integration level.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] Currently, in the production process of solar cell electrodes, the patterning mask process includes a loading process, a patterning process, and an unloading process set on a conveying path. Among them, the loading process loads the solar cell to the patterning process for the preparation of the patterned mask layer.

[0061] Thermal inkjet printing uses a thermally fusible material as the printing medium. Before use, the material is solid; during application, it is melted into a liquid state by heat energy within the inkjet unit and then sprayed onto the surface of a solar cell, where it solidifies to form a patterned mask. Considering production efficiency, there is an urgent need to develop a suitable patterned equipment loading device for thermal inkjet printing.

[0062] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0063] According to an embodiment of the present invention, a graphical equipment feeding device is provided, comprising: a feeding conveyor line 1, a flipping mechanism 2, and a cooling mechanism 3.

[0064] like Figure 1 and Figure 6 As shown, the feeding conveyor line 1 is used to transport substrates 8 that have not yet undergone hot melt inkjet printing or substrates 8 that have undergone one-sided hot melt inkjet printing. The feeding conveyor line 1 has two sections, located upstream and downstream of the flipping mechanism 2 and cooling mechanism 3, respectively. The flipping mechanism 2 and cooling mechanism 3 are installed between the two feeding conveyor lines 1 and connected in series. The flipping mechanism 2 has several flipping stations, which sequentially receive substrates 8 transported by the upstream feeding conveyor line 1 and flip the substrates 8 over within a preset time before placing them on the downstream feeding conveyor line 1. The flipping mechanism 2 is installed inside the cooling mechanism 3, which cools the substrates 8 on the flipping mechanism 2 to a preset temperature within a preset time.

[0065] In this embodiment, substrate 8 is a battery cell.

[0066] The patterning device performs hot melt inkjet printing at the printing station 41 to prepare the mask layer. The hot melt inkjet printing uses hot melt material as the printing material. The printing material is solid before use, and is melted into liquid in the inkjet unit by heat energy during use, and is then sprayed onto the surface of the solar cell panel to form a patterned mask. The printing material is usually selected to have a viscosity of 0.1 mPa-s to 20 mPa-s at a temperature greater than 50°C, and a viscosity greater than or equal to 10,000 mPa-s or be solid at a temperature 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.

[0067] When the surface of the substrate 8 is inkjet printed at the printing station 41, a certain time is required for the internal solidification of the pattern mask formed by condensation on the surface of the substrate 8. In this embodiment, the turnover mechanism 2 and the cooling mechanism 3 are arranged on the feeding conveying line 1. The turnover mechanism 2 not only turns over the substrate 8, but also allows the substrate 8 to stay on it for a period of time during the turnover. The cooling mechanism 3 cools the turnover mechanism 2 and the ambient temperature of the turnover mechanism 2 to a preset temperature. The substrate 8 is cooled by the cooling mechanism 3 immediately after being received by the turnover mechanism 2, and is cooled to the preset temperature by the cooling mechanism 3 within a preset time after being turned over to the downstream of the feeding conveying line 1 of the turnover mechanism 2, and is then output to the printing station 41 by the feeding conveying line 1 downstream of the turnover mechanism 2. The printing station 41 performs inkjet printing on the inkjet position on the surface of the substrate 8. The preset temperature allows the mask of the inkjet position to be cooled rapidly, and the mask layer on the surface of the substrate 8 is rapidly and fully solidified. On the one hand, this is beneficial to shorten the time for the mask layer on the surface of the substrate 8 to be fully solidified, thereby improving the production efficiency. On the other hand, this is beneficial to improve the quality of the mask pattern. At the same time, this is beneficial to prevent the local temperature of the substrate 8 in contact with the turnover mechanism 2 from rising, thereby ensuring the integrity of the mask pattern on the substrate 8. Moreover, the turnover and cooling are implemented on the feeding conveying line 1, which reduces the length of the conveying line, and the cooling and turnover are implemented at the same station, thereby enhancing the integration level of the device.

[0068] In some embodiments, the turnover mechanism 2 and the cooling mechanism 3 are arranged on the feeding conveying line 1. Figures 3 to 5As shown, the flipping mechanism 2 includes a support 21, a drive unit 22, and a rotating component assembly. The support 21 is fixed between two sections of the feeding conveyor line 1. The drive unit 22 is a motor, fixed on the support 21, and the axis of the output shaft of the drive unit 22 extends perpendicularly to the transmission direction of the feeding conveyor line 1. At least one rotating component assembly is provided, with a rotating shaft or connecting hole at its center. The rotating component assembly is connected to the output shaft of the drive unit 22 via the rotating shaft or connecting hole to fix it to the drive unit 22. The rotating component assembly has several slots 24, the width of which is greater than the thickness of the substrate 8, and can be set according to actual conditions. The slots 24 are used to engage the substrate 8. The drive unit 22 drives the rotating component assembly to rotate, flipping the substrate 8 and placing it on the feeding conveyor line 1 downstream of the flipping mechanism 2.

[0069] The substrate 8 is held in the slot 24. After the substrate 8 held in the slot 24 rotates synchronously with the rotating parts, it can be flipped over. The structure is simple and easy to implement.

[0070] In this embodiment, as Figures 3 to 5 As shown, the rotating assembly includes two rotating components 23, which are coaxial and spaced apart from each other along the axial direction of the output shaft of the drive component 22. There is an installation gap between the two rotating components 23, and two support components 25 are disposed within this gap, corresponding to the two rotating components 23. Each of the two rotating components 23 has several slots 24, which are arranged one-to-one. The width of each slot 24 matches the thickness of the substrate 8, allowing the substrate 8 to be inserted into the slots 24 to jointly clamp the substrate 8 and increase the stability of the clamped substrate 8.

[0071] Specifically, such as Figures 3 to 5 As shown, the rotating component 23 includes a cylindrical structure center and multiple fan blades fixed to the periphery of the cylindrical structure. The multiple fan blades are evenly spaced along the circumference of the cylindrical structure, and a groove is formed between two fan blades.

[0072] Alternatively, the rotating component 23 can be a plate-shaped disc structure. Two rotating components 23 can be separately fixed to opposite sides of a cylindrical structure, or the two rotating components 23 can be integrated as one unit. Several slots 24 on each rotating component 23 are evenly spaced along the axis of the rotating component 23, and each slot 24 is radially positioned along the rotating component 23, with its opening facing away from the center of the corresponding rotating component 23. When the rotating component 23 rotates 180°, the substrate 8 rotates 180° synchronously, thus enabling the substrate 8 to be flipped. After the rotating component 23 rotates 180°, the substrate 8 is flipped and placed on the feeding conveyor line 1 downstream of the flipping mechanism 2.

[0073] In this embodiment, as Figures 3 to 5As shown, the plurality of clamping grooves 24 are evenly arranged on the rotating member 23, and each clamping groove 24 extends radially. For example, the clamping grooves 24 can be evenly arranged in 10, 8, etc. When one of the clamping grooves 24 clamps the substrate 8 and rotates, the other adjacent clamping groove 24 will also rotate to the clamping position and clamp another substrate 8, and so on. When the clamping groove 24 clamping the substrate 8 rotates 180° and unloads, the rotating member 23 will continuously rotate and rotate the corresponding substrate 8 by 180° and unload, thereby improving the unloading efficiency.

[0074] In this embodiment, each rotating member 23 is provided with a support member 25 on the inner side, i.e. two rotating members 23 in each rotating member group are respectively provided with two support members 25 in the installation gap between the two rotating members 23, and each support member 25 is attached to the corresponding rotating member 23.

[0075] The support member 25 can be a disc structure, or a cylindrical structure including a plurality of fan blades fixed on the circumferential side of the cylindrical structure. The structure of the support member 25 is the same as that of the rotating member 23, and the plurality of fan blades are evenly spaced along the circumferential direction of the cylindrical structure, and the support groove is formed between two fan blades.

[0076] The outer diameter of the support member 25 is smaller than that of the rotating member 23, and a plurality of support grooves 26 are formed on the support member 25 along the circumferential direction. The number of the plurality of support grooves 26 on the support member 25 is the same as that of the plurality of clamping grooves 24 on the corresponding rotating member 23, and the shape and angle of the plurality of support grooves 26 are the same as those of the plurality of clamping grooves 24, so that the plurality of support grooves 26 and the plurality of clamping grooves 24 are one-to-one corresponding. The substrate 8 in the clamping groove 24 is supported by the support groove 26, which improves the stability of the clamping groove 24 during the overturning process and reduces the breakage rate of the substrate 8.

[0077] The overturning mechanism 2 described above realizes the overturning of the substrate 8 during the overturning process. Compared with overturning the substrate 8 by a mechanical hand device, the substrate 8 does not need to stay on the upstream and downstream unloading conveying line 1 of the overturning mechanism 2, which improves the overturning efficiency. Moreover, the structure of the overturning mechanism 2 is simpler than that of the complex mechanical hand device.

[0078] In another embodiment, as Figure 2As shown in the figure; the cooling device includes a shell 31 and a cold air system 32, the shell 31 covers the outside of the turnover mechanism 2, and the cold air system 32 is arranged on the shell 31, and the cold air system 32 is suitable for blowing cold air in the space enclosed by the shell 31 to reduce the temperature. In this embodiment, the opposite sides of the shell 31 are respectively provided with an opening, so that the substrate 8 upstream of the turnover mechanism 2 enters the turnover mechanism 2, and the substrate 8 turned over by the turnover mechanism 2 enters the downstream feeding conveying line 1. The shell 31 has a space, the turnover mechanism 2 is arranged in the space, and the cold air system 32 cools the ambient temperature in the shell 31, so that the turnover mechanism 2 can be cooled. The cold air system 32 includes a cold air machine, which can be arranged at the top of the shell 31, and the cooling effect of the ambient temperature in the shell 31 is better.

[0079] According to the embodiment of the utility model, on the other hand, a kind of graphical equipment is further provided, including figure printing mechanism 4, unloading conveying line 5, material moving mechanism and above graphical equipment feeding device. Figure printing mechanism 4 is used to carry out hot melt inkjet printing to substrate 8, and unloading conveying line 5 is used to convey substrate 8 after hot melt inkjet printing.

[0080] Graphical equipment feeding device is installed in the upstream of figure printing mechanism 4, and unloading conveying line 5 is arranged in the downstream of figure printing mechanism 4, and material moving mechanism is provided with two, and two material moving mechanisms are respectively arranged between feeding conveying line 1 and figure printing mechanism 4, and between figure printing mechanism 4 and unloading conveying line 5. Figure printing mechanism 4, unloading conveying line 5, material moving mechanism and above graphical equipment feeding device form U-shaped conveying line, and reduce floor area.

[0081] In one embodiment, as shown in the figure; Figure 1 Feeding conveying line 1 and unloading conveying line 5 are provided with a conveying belt, and figure printing mechanism 4 is provided with a figure printing station 41 corresponding to a conveying belt, and material moving mechanism includes linear material moving assembly 61, which is arranged between feeding conveying line 1 and figure printing mechanism 4, and between figure printing mechanism 4 and unloading conveying line 5. Transported is single substrate 8, and substrate 8 is square substrate, i.e. the same length and width substrate 8.

[0082] In this graphic processing device, the loading conveyor line 1 and the unloading conveyor line 5 are arranged parallel to each other and in opposite directions. The conveying direction of the printing station 41 on the printing mechanism 4 is perpendicular to both of them. Since the square substrate is a substrate 8 with the same length and width, the linear transfer component 61 located between the loading conveyor line 1 and the printing mechanism 4 can directly move the substrate 8 from the loading conveyor line 1 to the printing mechanism 4 without changing its direction. Similarly, the substrate 8 that has been inkjet printed on the printing mechanism 4 can be moved to the unloading conveyor line 5 located between the printing mechanism 4 and the unloading conveyor line 5 without changing its direction. In the above transfer process, the substrate 8 does not need to be deflected by 90° in the plane, nor does it need to have its length and width reversed, making the use of the linear transfer component 61 more cost-effective.

[0083] In another embodiment, such as Figure 6 As shown, multiple conveyor belts are installed on both the loading conveyor line 1 and the unloading conveyor line 5. In this embodiment, two conveyor belts are installed on both the loading conveyor line 1 and the unloading conveyor line 5. The printing mechanism 4 has two printing stations 41 corresponding to the two conveyor belts. The material transfer mechanism is a rotary material transfer assembly 62, which is located between the loading conveyor line 1 and the printing mechanism 4, and between the printing mechanism 4 and the unloading conveyor line 5. Two substrates 8 are transported simultaneously. The substrates 8 are rectangular substrates, meaning they have different lengths and widths.

[0084] In this graphic processing device, the loading conveyor line 1 and the unloading conveyor line 5 are arranged parallel to each other and in opposite directions. The conveying directions of the two printing stations 41 on the printing mechanism 4 are perpendicular to both of them. Since the rectangular substrates are substrates 8 with different lengths and widths, and when transferring the substrates 8 from the loading conveyor line 1 to the printing mechanism 4, and when transferring the substrates 8 from the printing mechanism 4 to the unloading conveyor line 5, their positions need to be changed. Therefore, a rotating material transfer assembly 62 is used. The rotating material transfer assembly 62, located between the loading conveyor line 1 and the printing mechanism 4, picks up the two rectangular substrates on the loading conveyor line 1 and moves them to the printing mechanism 4. During this process, the two rectangular substrates need to be deflected by 90° in a plane, so that their relative positions change, thereby matching the two printing stations 41 on the printing mechanism 4. For example... Figure 6As shown, the conveying direction of the feeding conveying line 1 is the first direction, the second direction is perpendicular to the first direction in the horizontal plane, the conveying direction of the printing station 41 on the printing mechanism 4 is the second direction, and the two printing stations 41 are arranged along the first direction. The two substrates 8 on the different conveying belts on the feeding conveying line 1 are sequentially arranged in the second direction, and become sequentially arranged along the first direction when the rotating transferring assembly 62 is moved to the printing mechanism 4. Similarly, the rotating transferring assembly 62 between the printing mechanism 4 and the discharging conveying line 5 can move the inkjet printed substrates 8 on the printing mechanism 4 to the discharging conveying line 5. In the process of sucking the two inkjet printed rectangular substrates on the printing mechanism 4 and moving them to the discharging conveying line 5, the two rectangular substrates need to be deflected by 90° in the plane, so that the relative positions of the two rectangular substrates are changed, so as to match the two conveying belts on the discharging conveying line 5. At this time, the entire conveying line during multi-station printing is designed in a U shape, and a plurality of conveying belts and the rotating transferring assembly 62 are used to convey the substrates 8 to the corresponding multi-station of the printing mechanism 4, so that a production line does not need to be rearranged outside the circle, and the structure is simple and space-saving.

[0085] In some other embodiments, the rotating piece group is arranged corresponding to the conveying belt. When there is only one conveying belt on the feeding conveying line 1, the rotating piece group is also arranged only one. When there are a plurality of conveying belts on the feeding conveying line 1, a plurality of rotating piece groups are arranged on one driving piece 22, and each rotating piece group corresponds to the flipping of the substrates 8 on one conveying line. The fan wheel blades of the rotating piece 23 and the support piece 25 are provided with a row of through holes, which can reduce the weight and will not hinder the circulation of cold air, and are beneficial to air cooling.

[0086] As shown in FIG. 6, the rotating transferring assembly 62 is arranged on the conveying line between the printing mechanism 4 and the discharging conveying line 5. The rotating transferring assembly 62 is arranged on the conveying line between the printing mechanism 4 and the discharging conveying line 5. Figure 7As shown, the conveying belt can be combined by a plurality of conveying units 7 along the conveying direction, the conveying unit 7 comprises two conveying belts 78, the two conveying belts 78 are arranged at intervals, and the two conveying belts 78 form an avoiding space; wherein the rotating piece 23 is arranged in the avoiding space.
