A light-shielding and protective nozzle assembly with a quick-release structure

Abstract

This utility model discloses a light-shielding printhead assembly with a quick-release structure, including a base, a printhead assembly, and a baffle. The base has multiple through-slots, and the printhead assembly has multiple nozzles distributed along a predetermined direction. The spraying assembly is installed in the through-slots, and the nozzles are located in the area of ​​the through-slots. The baffle is located below the printhead assembly and is positioned below the through-slots via a quick-release structure. The baffle has continuously extending through-holes, which are opposite to the nozzles, and a predetermined distance is provided between the through-holes and the nozzles. By providing a distance between the nozzles and the bottom wall of the base, the scattered light from the curing assembly can be effectively reduced from irradiating the nozzles, thereby reducing the curing of UV ink. Furthermore, by ensuring a predetermined distance between the nozzles and the through-holes, it can be ensured that ink droplets can pass through the through-holes and be sprayed onto the surface of the lithium battery while maintaining their spray distance.

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 assembly with a quick-release structure. Background Technology

[0002] As the efficiency of spray printing increases, the number of nozzles used will increase (in the form of micro-holes). The more nozzles there are, the higher the probability of curing will be for some micro-holes when the flow rate is uneven.

[0003] 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.

[0004] However, achieving rapid cleaning while avoiding nozzle clogging is the key to the design. Utility Model Content

[0005] The main purpose of this invention is to propose a light-shielding protective nozzle assembly with a quick-release structure, which aims to reduce nozzle clogging while enabling rapid disassembly of the baffle.

[0006] To achieve the above objectives, this utility model proposes a light-shielding and protective nozzle assembly with a quick-release structure, comprising:

[0007] The base has multiple through slots.

[0008] A nozzle assembly having a plurality of nozzles distributed along a predetermined direction, the nozzle assembly being installed in a through groove, the nozzles being located in the area of ​​the through groove;

[0009] A baffle is located below the nozzle assembly.

[0010] The baffle is located below the through groove via a quick-release structure;

[0011] 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.

[0012] 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.

[0013] Additionally, when there is no ink droplet solidification in the nozzle orifice of the printhead assembly, the baffle needs to be cleaned. However, the inner diameter of the through hole in the baffle is larger than the diameter of the nozzle, thus reducing ink droplet solidification. Furthermore, the quick-release structure enables rapid cleaning of the baffle, improving production efficiency. Attached Figure Description

[0031] like Figures 1 to 4 As shown, a light-shielding protective nozzle assembly with a quick-release structure includes,

[0032] Base 1, wherein the base 1 is provided with a plurality of through slots 10;

[0033] The nozzle assembly 2 is provided with a plurality of nozzle holes 20 distributed along a predetermined direction. The nozzle assembly is installed in the through groove 10, and the nozzle holes 20 are located in the area of ​​the through groove 10.

[0034] Baffle 3 is located below the nozzle assembly 2.

[0035] The baffle 3 is located below the through groove 10 via a quick-release structure;

[0036] 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 is provided between the through hole 30 and the spray hole 20.

[0037] 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.

[0038] In addition, when there is no ink droplet solidification in the nozzle 20 of the printhead assembly 2, the baffle 3 needs to be cleaned. However, the inner diameter of the through hole 30 of the baffle 3 is larger than the diameter of the nozzle 20, so the solidification of ink droplets can be reduced. Furthermore, the quick-release structure enables the baffle 3 to be cleaned quickly, thereby improving production efficiency.

[0039] 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;

[0040] The distance between the nozzle 20 and the through hole 30 is less than 2 mm.

[0041] By using appropriate spacing, both the predetermined spacing and the predetermined processing stability (i.e., spraying range) can be guaranteed.

[0042] In this embodiment of the utility model, the outer periphery of the bottom wall of the through groove 10 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, and the periphery of the baffle 3 is provided in the recessed groove 4.

[0043] The settling tank and the baffle 3 are respectively provided with a first magnetic component 51 and a second magnetic component 52 that cooperate with each other. They are installed by permanent magnets, which makes disassembly more convenient.

[0044] Specifically, the base 1 is provided with a plurality of positioning parts 61 at the corner end of the through groove 10, and the baffle 3 is provided with a locking part 62 that cooperates with the positioning parts 61.

[0045] In this embodiment of the utility model, a side groove 7 is provided in the same direction for multiple positioning parts, and the locking part extends into the side groove 7 and mounts the baffle 3 on the base 1.

[0046] Specifically, positioning beads, magnetic components, or damping pads can be installed in the side groove 7 to achieve the installation of the baffle 3.

[0047] Specifically, the upper wall of the positioning part is provided with a through groove 10, and the side wall of the baffle 3 is provided with a spring plunger 8 that cooperates with the through groove 10. The spring plunger 8 can slide between the position of extending into the baffle 3 or extending out of the baffle 3, thereby realizing the installation and fixation of the baffle 3.

[0048] In this embodiment of the invention, the lower wall of the positioning part is an inclined surface 80, thereby realizing the inward retraction of the spring ball.

[0049] Specifically, the positioning part protrudes from the lower wall of the base 1, the printhead is mounted on the base plate, and a small section protrudes from the bottom. The printhead protection plate has four slots corresponding to four sets of nozzle positions, and the rest of the area covers the nozzle positions with a 2mm gap from the printhead protection plate, so that the nozzle positions are not illuminated. Under normal production conditions, continuous ink output printing will not occur, and no additional printhead maintenance is required. It can continue to produce and is not afraid of impacts from external objects. The quick-release design allows for better disassembly, cleaning, and replacement of the protection plate.

[0050] In this embodiment of the invention, the nozzles are distributed in a straight line and the through holes 30 are distributed in a strip shape. Of course, the specific distribution of the nozzles can be designed according to actual needs.

[0051] 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.
