When the conventional spraying equipment is in flow operation, for the same face and the edges on the same face of the square battery device, three sprayings are required at two spraying stations. That is, in the direction of the material incoming, there is a spraying process in which the square battery device to be sprayed deviates from the material incoming direction once, so-called "reverse" spraying. In this way, it interferes with the subsequent incoming materials and ultimately affects the production efficiency. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0043] In the related technical field, battery devices need to be insulated before leaving the factory, that is, a layer of insulating layer needs to be sprayed on the surface of the battery device to achieve the purpose of insulation protection. However, for square battery devices, six surfaces, edges, and vertices need to be sprayed. When conventional spraying equipment performs flow operation, for the same surface and the edges on the same surface of a square battery device, three sprays are required at two spraying stations. That is, in the direction of the incoming material, there is a spraying process in which the square battery device to be sprayed deviates from the direction of the incoming material once, so-called "reverse" spraying, and the overall spraying process is stagnant. In this way, it interferes with the subsequent incoming materials and ultimately affects the production efficiency.

[0044] In view of this, embodiments of the present application provide a digital printing UV spraying whole machine device, the incoming material transmission line of which includes at least one loop transmission line, a side printing and forming station and a large surface printing and forming station are arranged on the loop transmission line, and a side printing and forming device is arranged at the side printing and forming station; a large surface printing and forming device is arranged at the large surface printing and forming station; thus, the spraying object is transmitted in a loop sequence on the loop transmission line, and the insulation layer coating of the side and the large surface is completed in turn.

[0045] Please refer to Figures 1 to 4 , in a first aspect, embodiments of the present application provide a digital printing UV spraying whole machine device 100, including an incoming material transmission line 10, a side printing and forming device 20 and a large surface printing and forming device 30.

[0046] The incoming material transmission line 10 includes at least one group of loop transmission lines 11, the loop transmission line 11 has a side printing and forming station 10a and a large surface printing and forming station 10b; the side printing and forming device 20 is arranged at the side printing and forming station 10a; the large surface printing and forming device 30 is arranged at the large surface printing and forming station 10b; wherein, the object to be sprayed is transmitted in a loop sequence on the loop transmission line 11, and passes through the side printing and forming station 10a and the large surface printing and forming station 10b.

[0047] It can be understood that the incoming material transmission line 10 is a transmission device for transmitting the object to be sprayed. Among them, the loop transmission line 11 refers to a transmission device with a loop shape, and the loop transmission line 11 can also be understood as a transmission device with a closed transmission line. That is to say, the loop transmission line 11 can also be a transmission device with a shape such as a triangle, a circle, an ellipse, etc.

[0048] The side printing and forming station 10a refers to a station for coating the insulation layer on the side of the object to be sprayed, and the large surface printing and forming station 10b refers to a station for coating the insulation layer on the large surface of the object to be sprayed. Among them, for a square shell battery, it has four sides and two large surfaces.

[0049] Here, the type of the printing and forming device is determined according to the spraying direction of the nozzle. The side printing and forming device 20 refers to a device in which the nozzle sprays the insulation layer in a horizontal direction. Among them, the side printing and forming device 20 includes two actions of spraying the insulation layer and curing the insulation layer; the large surface printing and forming device 30 refers to a device in which the nozzle sprays the insulation layer in a vertical direction. Among them, the large surface printing and forming device 30 includes two actions of spraying the insulation layer and curing the insulation layer.

[0050] In summary, the object to be sprayed is sequentially transported in a loop on the loop conveyor line 11. That is, along the transport direction, it passes through each work station in turn. For example, it flows from the starting work station to the end work station to complete one spraying and printing, and it can also pass through the starting work station and the end work station multiple times to complete multiple spraying and printing, and can continuously circulate and complete the corresponding process actions. The transport speed of the object to be sprayed on the loop conveyor line 11 is faster, and there is no situation of "reverse" spraying, which also provides a prerequisite for the simultaneous curing of the insulating layer on each surface, edge and vertex of the object to be sprayed.

[0051] The digital printing UV spraying whole machine device 100 of the present utility model, its incoming material conveyor line 10 includes at least one loop conveyor line 11, and the object to be sprayed is sequentially transported in a loop on the loop conveyor line 11. That is, each object to be sprayed passes through each work station in turn along the transport direction, and corresponding processes are implemented at the corresponding work stations. For example, the spraying and curing of the side insulating layer of the object to be sprayed are carried out at the side printing and forming work station 10a, and the spraying and curing of the large surface insulating layer of the object to be sprayed are carried out at the large surface printing and forming work station 10b. In this way, the spraying efficiency and production capacity of the digital printing UV spraying whole machine device 100 provided by the embodiments of the present application are higher.

[0052] Please refer to Figures 1 to 4 , in some embodiments, the loop conveyor line 11 includes a first sub-conveyor line 111, a first transfer line 112, a second sub-conveyor line 113 and a second transfer line 114 arranged in sequence along the incoming material transport direction. The opposite ends of the first transfer line 112 are respectively connected to the first sub-conveyor line 111 and the second sub-conveyor line 113, and the opposite ends of the second transfer line 114 are respectively connected to the first sub-conveyor line 111 and the second sub-conveyor line 113;

[0053] The side printing and forming work station 10a is located on one or both of the first sub-conveyor line 111 and the second sub-conveyor line 113, and the large surface printing and forming work station 10b is located on one or both of the first sub-conveyor line 111 and the second sub-conveyor line 113.

[0054] Understandably, in this embodiment, taking the shape of the looped transmission line 11 as a square as an example, the looped transmission line 11 includes four parts. Among them, the first sub-transmission line 111 and the second sub-transmission line 113 are transmission lines for implementing the spraying of the insulating layer on the object to be sprayed. That is, the side printing and forming station 10a and the large surface printing and forming station 10b can be set on the corresponding sub-transmission lines, while the first transfer line 112 and the second transfer line 114 are transmission lines for implementing the transmission commutation of the object to be sprayed. That is, the transfer line is used to transfer the object to be sprayed from one sub-transmission line to another sub-transmission line. Therefore, in terms of the setting selection of the side printing and forming station 10a and the large surface printing and forming station 10b, they can be set on one or both of the two sub-transmission lines.

[0055] Exemplarily, as Figure 1 described, the side printing and forming station 10a can be set on the first sub-transmission line 111; and, the large surface printing and forming station 10b can be set on the second sub-transmission line 113.

[0056] Or, as Figure 2 shown, the side printing and forming station 10a and the large surface printing and forming station 10b can be set on the first sub-transmission line 111; and, the side printing and forming station 10a and the large surface printing and forming station 10b can be set on the second sub-transmission line 113.

[0057] Please refer to Figure 1 and Figure 4 , in some embodiments, the first sub-transmission line 111, the first transfer line 112, the second sub-transmission line 113, and the second transfer line 114 are arranged horizontally; or,

[0058] the first sub-transmission line 111, the first transfer line 112, the second sub-transmission line 113, and the second transfer line 114 are arranged vertically.

[0059] Understandably, that the sub-transmission lines and the transfer lines are arranged horizontally means that the sub-transmission lines and the transfer lines are set at the same horizontal height or the horizontal heights are not much different.

[0060] And, that the sub-transmission lines and the transfer lines are arranged vertically means that there is an obvious height difference between the sub-transmission lines, and, the transfer lines are arranged vertically.

[0061] Of course, the looped transmission line 11 can be arranged according to the actual size of the factory building area to improve the space utilization rate of the factory building.

[0062] Please refer to Figure 1 and Figure 3, in some embodiments, the number of the side printing and forming devices 20 is at least two, and at least one side printing and forming device 20 is located on one side or both sides of the first sub-transmission line 111; and / or,

[0063] at least one side printing and forming device 20 is located on one side or both sides of the second sub-transmission line 113.

[0064] It can be understood that the first sub-transmission line 111 should have two opposite sides along the transmission direction. Similarly, the second sub-transmission line 113 also has two opposite sides along the transmission direction. Then, the side printing and forming device 20 can be selected on one side or both sides of the corresponding sub-transmission line.

[0065] Here, if the side printing and forming devices 20 are arranged on both sides of the sub-transmission line, then the spraying and forming of the insulating layers on two sides of the object to be sprayed can be completed on the corresponding sub-transmission line, further shortening the transfer and transmission time and improving the spraying efficiency.

[0066] Please refer to Figure 2 and Figure 3 , in some embodiments, the side printing and forming device 20 includes a side printing and spraying device 21 and a side pre-curing device 22 arranged in sequence along the transmission direction.

[0067] It can be understood that the side printing and spraying device 21 is a device for spraying the insulating layer on the side of the object to be sprayed, and the side pre-curing device 22 is a device for curing the insulating layer on the surface of the object to be sprayed. Therefore, there is an arrangement in a front-to-back order.

[0068] Please refer to Figure 2 and Figure 3 , in some embodiments, the large-surface printing and forming device 30 includes a large-surface printing and spraying device 31 and a large-surface pre-curing device 32 arranged in sequence along the transmission direction.

[0069] It can be understood that the large-surface printing and spraying device 31 is a device for spraying the insulating layer on the large surface of the object to be sprayed, and the large-surface pre-curing device 32 is a device for curing the insulating layer on the surface of the object to be sprayed. Therefore, there is an arrangement in a front-to-back order.

[0070] Please refer to Figures 1 to 4 , in some embodiments, the incoming material transmission line 10 further has at least one final curing station 10c. In the transmission direction, the final curing station 10c is located after the large-surface printing and forming station 10b or the side printing and forming station 10a. The digital printing UV spraying whole machine equipment 100 further includes a final curing device 40, and the final curing device 40 is located at the final curing station 10c.

[0071] It is understandable that since the object to be sprayed needs to be continuously circulated and transported on the incoming material transmission line after the insulation layer is applied, the insulation spray material on the large surface and side of the object to be sprayed is easy to flow and drip. Therefore, it is necessary to set a pre-curing process in the previous spraying process to pre-curing the insulation spray material to reduce or even solve the problem of dripping of the insulation spray material. Similarly, it is also necessary to add a final curing station 10c to uniformly cure the insulation coating at various locations on the object to be sprayed to finally form an insulation layer.

[0072] In summary, a final curing station 10c is added to the incoming material transmission line 10, and the final curing station 10c is arranged after the large-area printing and forming station 10b, and the final curing device 40 is arranged at the final curing station 10c. Here, the final curing device 40 is a device for achieving complete solidification of the insulating coating to form the final form of the insulating layer.

[0073] For example, the final curing station 10 c may be disposed on the first sub-transmission line 111 and / or the second sub-transmission line of the loop-shaped transmission line 11 .

[0074] Please refer to Figure 1 In some embodiments, the incoming material transmission line 10 also includes a unloading material transmission line 12, which is connected to the return transmission line 11. The unloading material transmission line 12 has a final curing station 10c. In the transmission direction, the final curing station 10c is located after the large-surface printing and molding station 10b or the side printing and molding station 10a. The digital printing UV spraying equipment 100 also includes a final curing device 40, which is located at the final curing station 10c.

[0075] It can be understood that the unloading transmission line 12 is used for unloading. Similarly, the final curing station 10c is set on the unloading transmission line 12, and the final curing device 40 is set at the final curing station 10c to achieve complete solidification of the insulating coating to form the final shape of the insulating layer.

[0076] Here, the final curing station 10c is arranged on the unloading transmission line 12, so that the final curing device 40 can be further away from the pre-curing process position to reduce the impact on the pre-curing process.

[0077] Please refer to Figure 5 In some embodiments, the final curing device 40 includes a final curing main body device 41 and a protective cover 42 for isolating the final curing main body device 41 .

[0078] Understandably, the final curing main device 41 is the device mainly implementing the final form of the insulating layer formed by the complete solidification of the insulating paint. The protective cover 42 isolates and protects the final curing main device 41. For example, it can be protected by covering to reduce the influence of the final curing main device 41 on the nozzles of the side printing and spraying device and the large surface printing and spraying device, so that the ink in each nozzle will not be prematurely solidified, resulting in nozzle blockage.

[0079] Here, the structural form of the protective cover 42 is not limited, as long as it can achieve the isolation and protection effect.

[0080] Please refer to Figure 1 , in some embodiments, the incoming material transmission line 10 further includes a loading transmission line 13. The loading transmission line 13 is connected to the loop transmission line 11. The loading transmission has a visual inspection station. In the transmission direction, the visual inspection station is located before the side printing and forming station 10a or the large surface printing and forming station 10b. The digital printing UV spraying whole machine device 100 further includes a visual guiding device, and the visual guiding device is located at the visual inspection station.

[0081] Understandably, the loading transmission line 13 is used for loading. The visual inspection station is used for visually inspecting the incoming material and judging and determining the positions of the side, large surface, edge, and top corner of the object to be sprayed. Here, the visual guiding device is the device for completing the above judgment and determining the above process actions.

[0082] Please refer to Figure 2 , in some embodiments, the number of loop transmission lines 11 is two or more. The incoming material transmission line 10 includes an intermediate transfer transmission line 15, and the intermediate transfer transmission line 15 is connected to two adjacent loop transmission lines 11.

[0083] Understandably, in order to further improve the efficiency, two or more loop transmission lines 11 can be set, and an intermediate transfer transmission line 15 is set between the two loop transmission lines 11 for transferring the incoming material. For example, the intermediate transfer transmission line 15 can be used to reverse, flip, or rotate the incoming material. Of course, in some embodiments, manual transfer transmission can also be used.

[0084] Please refer to Figure 2 and Figure 3 , in some embodiments, the incoming material transmission line 10 further has a flipping and rotating station 10e. The flipping and rotating station 10e is located on the intermediate transfer transmission line 15 or the loop transmission line 11. The digital printing UV spraying whole machine device 100 further includes a flipping and rotating device 60, and the flipping and rotating device 60 is located at the flipping and rotating station 10e.

[0085] Understandably, the flipping and rotating station 10e is a station for flipping and / or rotating the object to be spray-coated. According to actual usage requirements, the flipping and rotating station 10e can be set on the intermediate transfer conveyor 15 or the loop conveyor 11.

[0086] In addition, the flipping and rotating device 60 is a device for implementing the flipping and / or rotating of the object to be spray-coated. For example, the flipping and rotating device 60 can be a manipulator, a flipping platform, a rotating platform, etc.

[0087] In a second aspect, an embodiment of the present application further provides a production line, including at least one of the above digital printing UV spraying integrated equipment 100.

[0088] The production line of the present utility model has higher spraying efficiency and productivity on the basis of having the above digital printing UV spraying integrated equipment 100.

[0089] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
