Description

Technical Field

[0001] This utility model relates to the field of lithium battery spraying mechanism, and in particular to a light-shielding and protective spray nozzle part. Background Technology

[0002] As the efficiency of spray printing increases, the number of nozzles used will increase (forming micro-hole piles). When there are more nozzles, the probability of some micro-holes curing under uneven flow rate will also increase. The main factor is that a larger number of nozzles inevitably requires a higher energy level from the curing lamp. However, the diffused light from the curing lamp can cause localized curing of the ink in the printhead, leading to nozzle blockage and affecting the smoothness of the print. Summary of the Invention

[0003] The main purpose of this invention is to propose a light-shielding and protective spray nozzle component, which aims to improve the existing spraying mechanism structure. Through the light-shielding design, the impact of the ultraviolet curing lamp on the spray nozzle is reduced while ensuring the stable use of the spray nozzle.

[0004] To achieve the above objectives, this utility model proposes a light-shielding and protective nozzle component, comprising: The base has multiple through slots. A nozzle assembly having a plurality of nozzles distributed along a predetermined direction; a spraying assembly being installed in a through groove, wherein the nozzles are located in the area of ​​the through groove. A baffle is disposed on the lower wall of the substrate and below the nozzle assembly. The baffle is provided with continuously extending through holes, which are arranged opposite to the spray holes, and a predetermined distance is provided between the through holes and the spray holes.

[0005] In practical design, by setting a gap between the nozzle and the bottom wall of the base, the scattered light from the curing component can be effectively reduced from irradiating the nozzle, thereby reducing the curing of UV ink. Furthermore, by ensuring a predetermined gap between the nozzle and the via, it can be ensured that the ink droplets can pass through the via and be sprayed onto the surface of the lithium battery while maintaining their spraying distance.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0011] like Figures 1 to 4 As shown, a light-shielding and protective nozzle component includes: Base 1, wherein the base 1 is provided with a plurality of through slots 10; The nozzle assembly 2 is provided with a plurality of spray holes 20 distributed along a predetermined direction. The spraying assembly is installed in the through groove 10, and the spray holes 20 are located in the area of ​​the through groove 10. Baffle 3 is disposed on the lower wall of the substrate and below the nozzle assembly 2. The baffle 3 is provided with a continuously extending through hole 30, which is arranged opposite to the spray hole 20, and a predetermined distance 100 is provided between the through hole 30 and the spray hole 20.

[0012] In the actual design, by providing a gap between the nozzle 20 and the bottom wall of the base 1, the scattered light from the curing component can be effectively reduced from irradiating the nozzle 20, thereby reducing the curing of the UV ink. Furthermore, by ensuring a predetermined gap between the nozzle 20 and the via 30, it can be ensured that the ink droplets can pass through the via 30 and be sprayed onto the surface of the lithium battery while ensuring their spraying distance.

[0013] Specifically, the nozzle assembly 2 is provided with an outwardly extending positioning plate 5 on its outer periphery. The positioning plate 5 is fixed to the upper wall of the base 1, that is, the nozzle assembly 2 is retracted into the through groove 10, thereby ensuring the distance between the nozzle hole 20 and the bottom wall of the through groove 10. The specific distance can also be improved according to the actual design.

[0014] In this embodiment of the invention, the fixing method is a screw or a buckle, which facilitates disassembly.

[0015] Specifically, a distance of 2-3.5 mm is provided between the end of the nozzle 20 and the bottom wall of the base 1.

[0016] In this embodiment of the invention, the distance between the spray hole 20 and the through hole 30 is less than 2mm. With a suitable distance, both the predetermined distance and the predetermined processing stability (i.e., spraying range) can be guaranteed.

[0017] Specifically, the outer periphery of the bottom wall of the through groove is provided with a recessed groove 4 for the base wall surface. The thickness of the recessed groove 4 is suitable for the baffle 3. The periphery of the baffle 3 is located in the recessed groove 4, thereby achieving that the bottom surfaces of the baffle 3 and the base are relatively horizontal, thus reducing the residual area.

[0018] In this embodiment of the utility model, the baffle 3 is provided with screw holes, which are arranged asymmetrically, thereby playing a role in preventing mistakes.

[0019] Furthermore, under normal production conditions, continuous ink output printing will not result in ink interruption, no additional printhead maintenance is required, production can continue indefinitely, and it is also resistant to impacts from external objects.

[0020] The baffle 3 can protect the nozzle wall from glare that could cause the nozzle holes 20 to become clogged. The parts are simple and the manufacturing process is not complicated, which effectively reduces costs. Tests show that no excessive nozzle maintenance is required. Short-term shutdowns do not affect the nozzle condition. The nozzle protection plate needs to be cleaned every 10 days during long-term use. There are no signs of contamination on the internal nozzles, and the protection effect is good.

[0021] Specifically, the nozzles 20 are distributed in a straight line, and the through holes 30 are distributed in a strip shape. Of course, the distribution of the nozzles 20 can be designed according to actual needs.

[0022] In this embodiment of the utility model, the through hole 30 is provided with four holes.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
