Description

TECHNICAL FIELD

[0001] The present application relates to the packaging technical field, in particular to a needle tube packaging box for electrohydrodynamic spraying. BACKGROUND

[0002] Electrohydrodynamic (EHD) printing is an additive manufacturing technique that enables ultra-high resolution printing. It is a non-vacuum, direct-write, non-contact and maskless process. EHD printing reduces the number of manufacturing steps, making it more cost-effective and material-efficient. EHD printing technology is used to manufacture microelectronic and nanoelectronic devices. EHD printing can be operated in two different printing modes; Drop-On-Demands (DOD) and continuous jetting. DOD utilizes droplet and drop stream jetting characteristics, while continuous jetting utilizes conical jetting for patterning and deposition of materials. The technology performs various coatings and printing on a variety of printable materials and substrates, and EHD printing technology has advantages in aspect ratio, performance improvement, flexibility of ink materials compared to other manufacturing technologies.

[0003] Regardless of DOD or continuous jetting, the needle tube made of glass material and its micron-level needle tip are very important components of the jetting device, especially the size and shape of the needle tip, which will directly affect the spraying effect and spraying quality, and the quality of the needle tip also affects the stability and life of the spraying. The needle tip of the needle tube on the market is easy to break in the micron range, which makes the transportation of the needle tube a key factor to ensure the structural integrity. In the related art, there is no device suitable for transporting needle tubes for electrohydrodynamic spraying, and the transportation devices for other tubular objects have the problems of insufficient stability and protection. Such devices will cause damage to the needle tube during transportation, and devices with acceptable stability and protection have the problem of inconvenient taking, which makes the needle tube transported by such devices prone to local damage such as needle tip breakage during taking. SUMMARY

[0004] Therefore, it is necessary to provide a needle tube packaging box for electrohydrodynamic spraying with good stability, protection, and avoiding damage to the needle tube during taking.

[0005] A needle tube packaging box for electrohydrodynamic spraying, the packaging box comprises:

[0006] a box body comprising an openable opening, and an accommodating space in the box body being in communication with the outside through the opening; and

[0007] The support member is arranged in the accommodating space, and comprises a containing part provided with at least one containing groove, and adjacent containing grooves are arranged at intervals, and the containing groove is used for accommodating the accommodating part of the middle part of the needle tube, and the support member is configured to fix the fixed part of the needle tube, and the fixed part of the needle tube is located at the end part or coincides with the accommodating part.

[0008] In one of the embodiments, the containing part comprises at least one first containing part provided with a first containing groove, and the first containing groove is composed of rigid plastic material and is used for matching the accommodating part of the needle tube.

[0009] Compared with foam, plastic material has a lower particle generation rate, which helps to reduce the pollution of particles in the production environment, and the processing process of plastic material also facilitates the realization of dust-free production, ensures the cleanliness of the needle tube during installation and transportation, and further ensures the quality of spraying.

[0010] In one of the embodiments, the support member comprises at least two support tables, and the first containing part is arranged at intervals between adjacent two support tables, and the support table is arranged at the fixed part of the end part of the needle tube.

[0011] In one of the embodiments, the support table comprises a support area in contact with the needle tube, and the support area is provided with a fixing part used for separable fixing of the fixed part.

[0012] The support table fixes the end part of the needle tube, improves the balance and stability of the fixing, and the non-fixed connection of the needle tube of the accommodating part enables the user to operate the accommodating part during installation and taking of the needle tube. This makes it easier for the user to access the accommodating area of the needle tube for taking operation, and avoids the breakage of the needle tube caused by the small elasticity and large hardness of the first containing part of rigid plastic material during taking and placing.

[0013] In one of the embodiments, the first containing groove has a slot, and the width of the slot is greater than the outer diameter of the needle tube.

[0014] This makes it easier for the user to access the accommodating area of the needle tube for taking operation, and avoids the breakage of the needle tube caused by the small elasticity and large hardness of the first containing part of rigid plastic material during taking and placing.

[0015] In one of the embodiments, the containing part comprises a second containing part provided with a containing groove, and the second containing groove is composed of deformable plastic material and is used for matching the accommodating part of the needle tube, and the accommodating part coincides with the fixed part.

[0016] Compared with the foam, the deformable plastic material has a lower particle generation rate, which helps to reduce the particle pollution in the production environment, and the processing of the plastic material facilitates the realization of dust-free production, ensures the cleanliness of the needle tube during installation and transportation, and further ensures the quality of spraying. The deformable plastic material is generally a soft plastic, which can prevent the needle tube from breaking due to excessive hardness of the material of the containing part when the needle tube is taken out.

[0017] In one of the embodiments, the second containing groove has a slot, and the width of the slot is less than the outer diameter of the needle tube.

[0018] In one of the embodiments, the inner diameter of the second containing groove is less than or equal to the outer diameter of the needle tube.

[0019] By means of the interference accommodation of the deformable material, the needle tube is tightly wrapped to achieve accommodation and fixation. After being put in, the needle tube is covered and cannot slide up and down, left and right, or forward and backward, thereby preventing the risk of needle collision during transportation. The two ends of the needle tube can be provided with support tables or can be suspended as free ends, facilitating the taking of the needle tube.

[0020] In one of the embodiments, the cross-sectional shape of the second containing groove is drop-shaped, and the second containing groove includes a wrapping part and a connecting part. The wrapping part matches the shape of the outer surface of the needle tube, and the connecting part is communicated between the slot and the wrapping part.

[0021] In one of the embodiments, the packaging box further includes a cover body, which is movably connected with the box body and used for closing the opening.

[0022] The packaging box described above contains multiple needle tubes by means of the support member, which are spaced and fixed to prevent impact during transportation. The containing groove is used to accommodate the middle part of the needle tube, and the needle tube can be fixed by the end part during accommodation. The containing groove only has an accommodation function, which not only fixes the needle tube to improve the stability of transportation, but also facilitates the taking of the needle tube. The packaging box described above can also fix and accommodate the middle part of the needle tube through the containing groove, and the free end can be taken without damaging the more fragile needle tip of the end part. This way ensures that the needle tube has a part that can be fixed, and the stability of the accommodation is good. The non-fixed part is convenient for taking operation.

[0035] Reference Figure 1 , Figure 1 The structure of the needle tube packaging box for electro-fluid spraying in an embodiment of the present application is shown. The packaging box provided in an embodiment of the present application is used to place a needle tube 1 for electro-fluid spraying, especially a needle tube 1 with a micron-level needle tip made of glass. Compared with a conventional metal needle tube 1, the glass needle tube 1 can be made smaller in size. Since the needle tip of the glass needle tube 1 can be processed to a micron level, the ink ejection amount and ejection direction can be accurately controlled, which is crucial for printing fine semiconductor device patterns and achieves the requirement of high-precision ejection printing. However, the needle tip of the glass needle tube 1 is easily damaged during picking up, transporting and using.

[0036] As Figure 2As shown, the needle tube 1 is tubular, comprising a containing portion 11 in the middle and a fixing portion 12 at least one of which can be at the end, one end of the needle tube 1 being a needle tip. The fixing portion 12 is also in the middle of the needle tube 1 when the containing portion 11 and the fixing portion 12 coincide.

[0037] The packaging box comprises a box body 100 and a support member. The box body 100 comprises an openable opening, and a containing space 110 is provided in the box body 100 and communicates with the outside through the opening. The support member is provided in the containing space 110 and comprises a containing piece provided with at least one containing groove, and adjacent containing grooves are arranged at intervals. The containing groove is used for containing the containing portion 11 in the middle of the needle tube 1, and the support member is configured to fix the fixing portion 12 of the needle tube 1, the fixing portion 12 of the needle tube 1 being at the end or coinciding with the containing portion 11.

[0038] The packaging box described above contains a plurality of needle tubes 1 by arranging the support member to be fixed at intervals to prevent impact during transportation. The containing groove is used for containing the containing portion 11 in the middle of the needle tube 1, and the containing tube can be fixed by the end portion at the same time. The containing groove only has a containing function, which makes the needle tube 1 fixed to improve the stability of transportation and facilitates the removal of the needle tube 1. The packaging box described above can also fix and contain the middle of the needle tube 1 through the containing groove, and the free end can be operated to take out, which will not damage the more fragile needle tip at the end. This way makes the needle tube 1 always have one part fixed, the containing stability is good, and the non-fixed part is convenient for taking operation.

[0039] In one embodiment, the containing piece comprises at least one first containing piece 200, and the first containing piece 200 is provided with a first containing groove 210, which is composed of a rigid plastic material and is used for matching the containing portion 11 of the needle tube 1.

[0040] The first containing piece 200 is in the shape of a long table, comprising an upper surface facing the opening, and the first containing groove 210 is recessed in the upper surface. The first containing groove 210 extends along a first direction to penetrate the width direction of the first containing piece 200, and the first direction is perpendicular to the length direction of the first containing piece 200. The needle tube 1 is arranged in the first containing groove 210 along the first direction, and the containing portion 11 matches the first containing groove 210.

[0041] In one embodiment, as shown in FIG. 2, the containing piece comprises at least one first containing piece 200, and the first containing piece 200 is provided with a first containing groove 210, which is composed of a rigid plastic material and is used for matching the containing portion 11 of the needle tube 1. Figure 5 , 6As shown, the first accommodating member 200 includes protruding portions 220 protruding from the upper surface of the first accommodating member 200 and recessed portions 230 recessed in the upper surface of the first accommodating member 200, the protruding portions 220 are arranged at intervals between the recessed portions 230, and a first accommodating groove 210 is recessed in the protruding portions 220, so that the first accommodating groove 210 as a whole protrudes from the upper surface of the first accommodating member 200 and is arranged above the needle tube to be placed. Specifically, the first accommodating groove 210 extends in a first direction to pass through each of the protruding portions 220. The protruding portions 220 can be provided in two, and the recessed portions 230 are arranged between the two protruding portions 220, and each of the protruding portions 220 corresponds to the non-fixed portion 12 of the needle tube. The recessed portions 230 extend in a second direction (which can be perpendicular to the first direction) or pass through the first accommodating member 200, and are arranged on one side of the protruding portions 220, corresponding to the non-fixed portion and the non-accommodating portion of the needle tube. Due to the presence of the recessed portions 230, a gap is formed between the lower portion of the needle tube and the recessed portions 230, which can be used by the user's hand or tool to enter, so as to facilitate the taking of the needle tube.

[0042] The first accommodating groove 210 is made of rigid plastic material, and the first accommodating member 200 as a whole or the structure near the first accommodating groove 210 is made of rigid plastic material. As a preferred embodiment, the first accommodating member 200 is made of rigid plastic material as a whole. The rigid plastic material is one or a combination of the following: polycarbonate (PC), polyoxymethylene (POM), polyester (PET or PBT), polystyrene (PS), ABS plastic, polypropylene (PP), polyethylene (PE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyamide (PA, commonly known as nylon), polytetrafluoroethylene (PTFE, trademark name Teflon), polyimide (PI). As a preferred embodiment, the first accommodating member 200 is made of polystyrene, ABS plastic, polypropylene, and polyethylene among the above, which has the advantages of convenient processing and low cost, and has strong durability. The filling and fixing structure material in the traditional transportation device is foam material, which is easy to produce particles or dust. After the particles or dust mix with the ink, it will form a section, block or produce obvious bubbles in the plastic tube, which will affect the continuous flow of the ink and cause the instability of the sprayed pattern. Plastic material has a lower particle generation rate than foam, which helps to reduce the pollution of particles in the production environment, and the processing process of plastic material also facilitates the realization of dust-free production, ensures the cleanliness of the needle tube 1 during installation and transportation, and further ensures the quality of spraying.

[0043] In one embodiment, the support member comprises at least two support tables 300, and the first accommodating member 200 is arranged between two adjacent support tables 300. The support table 300 is arranged at the fixed portion 12 of the end of the needle tube 1. The support table 300 comprises a support area in contact with the needle tube 1, and the support area is provided with a fixing member for detachably fixing the fixed portion 12.

[0044] At least one first accommodating member 200 and one support table 300 form an accommodating group. The first accommodating member 200 of each accommodating group matches the accommodating portion 11, and the support table 300 of each accommodating group matches the fixed portion 12. Thus, different positions of the needle tube 1 are fixed and accommodated, and in particular, the support table 300 is used to fix the end portion other than the needle tip. Figure 1 In the illustrated embodiment, one first accommodating member 200 and two support tables 300 form an accommodating group. The first accommodating member 200 of each accommodating group matches the accommodating portion 11, and the support table 300 of each accommodating group matches the fixed portion 12 at the needle tip and the fixed portion 12 away from the needle tip. Thus, both ends of the needle tube 1 are fixed, which improves the balance and stability of the fixing. The needle tube 1 is non-fixedly connected to the accommodating portion 11, and the user can operate the accommodating portion 11 when installing and taking the needle tube 1.

[0045] The support table 300 is in the shape of a long table, comprising an upper surface facing the opening, and the fixing member is arranged on the upper surface. Further, the material of the support table 300 is consistent with that of the first accommodating member 200, and the width of the support table 300 in the first direction is greater than that of the first accommodating member 200.

[0046] Specifically, the fixing member is an adhesive layer attached to the upper surface of the support table 300. Alternatively, the adhesive layer is a pressure-sensitive adhesive (PSA), such as double-sided tape. The adhesive strength of the adhesive layer is 2 N / cm to 6 N / cm, and the peel strength is less than 60°, so that the needle tube 1 is not damaged when peeled off, facilitating the peeling of the circular needle tube 1. The fixing member in the form of the adhesive layer improves the convenience of installation and taking, and reduces the production cost.

[0047] In one embodiment, the first accommodating groove 210 has a groove width greater than the outer diameter of the needle tube 1. The overall groove width of the first accommodating groove 210 is greater than the outer diameter of the needle tube 1, or the groove width of a partial area of the first accommodating groove 210 is greater than the outer diameter of the needle tube 1, and the groove width of the remaining partial area is equal to the outer diameter of the needle tube 1. This makes it easier for the user to contact the accommodating area of the needle tube 1 for taking operation, avoiding the breakage of the needle tube 1 due to the small elasticity and large hardness of the first accommodating member 200 made of rigid plastic material when taking and placing.

[0048] Further, the first accommodating groove 210 is arc-shaped or semi-circular, and the groove depth of the first accommodating groove 210 is smaller than the outer diameter of the needle tube 1, that is, the curvature of the arc-shaped or semi-circular first accommodating groove 210 is greater than the curvature of the needle tube 1, so that part of the needle tube 1 protrudes from the upper surface of the first accommodating groove 210, and the size of the notch is matched, so that the user can more easily contact the accommodation area of the needle tube 1 for picking operation.

[0049] In combination Figure 3 As shown, Figure 3 The structure of the needle tube 1 packaging box for electro-fluid spraying in another embodiment of the present application is shown. In one embodiment, the accommodating member includes a second accommodating member 400, and the second accommodating member 400 is provided with a second accommodating groove 410, which is composed of a deformable plastic material and is used to match the accommodation part 11 of the needle tube 1, and the accommodation part 11 and the fixed part 12 coincide.

[0050] The second accommodating member 400 is long table-shaped, including an upper surface facing the opening, and the second accommodating groove 410 is recessed in the upper surface. The second accommodating groove 410 extends along the first direction to penetrate the width direction of the second accommodating member 400, and the first direction is perpendicular to the length direction of the second accommodating member 400. The needle tube 1 is arranged in the second accommodating groove 410 along the first direction. In this embodiment, the accommodation part 11 and the fixed part 12 of the needle tube 1 coincide, both are the middle part of the needle tube 1, and match the second accommodating groove 410 to achieve accommodation and fixation.

[0051] The second accommodating groove 410 is composed of a deformable plastic material, and the second accommodating member 400 as a whole or the structure near the second accommodating groove 410 is rigid plastic material. As a preferred, the second accommodating member 400 is deformable plastic material as a whole. The deformable plastic material is one or a combination of the following: polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyether ether ketone (PEEK). As a preferred, the second accommodating member 400 adopts polypropylene and polyether ether ketone among the above, that is, it has the advantages of convenient processing and low cost, and also has strong durability. The deformable plastic material has a lower particle generation rate than foam, which helps to reduce particle pollution in the production environment. The processing of plastic material also facilitates dust-free production, ensuring the cleanliness of the needle tube 1 during installation and transportation, and further ensuring the quality of spraying. The deformable plastic material is generally soft, which can avoid the needle tube 1 from being broken due to excessive hardness of the accommodating member itself during picking and placing the needle tube 1. Further, the hardness of the second accommodating groove 410 is greater than that of the needle tube.

[0052] In one embodiment, the second accommodating groove 410 has a notch, and the width of the notch is smaller than the outer diameter of the needle tube 1. The inner diameter of the second accommodating groove 410 is smaller than or equal to the outer diameter of the needle tube 1.

[0053] Specifically, the width of the notch is less than the outer diameter of the needle tube 1, so that the fixing mode of the second accommodating groove 410 is a wrapping type. In particular, the second accommodating groove 410 is made of a deformable plastic material, the inner diameter of the second accommodating groove 410 is less than the outer diameter of the needle tube 1, and the fixing mode of the second accommodating groove 410 is an interference fit. Further, the second accommodating groove 410 covers at least 60% of the outer surface area of the fixed portion 12 of the needle tube 1. Through the interference fit of the deformed material, the needle tube 1 is tightly wrapped to achieve accommodation and fixation. After being put in, the needle tube 1 is covered and cannot slide up and down, left and right, front and back, preventing the risk of needle collision during transportation. The two ends of the needle tube 1 can be provided with a support table 300, or can be suspended as a free end, facilitating the taking of the needle tube 1.

[0054] In one embodiment, as shown in Figure 4 the cross-sectional shape of the second accommodating groove 410 is drop-shaped, the second accommodating groove 410 includes a wrapping portion 411 and a connecting portion 412, the wrapping portion 411 matches the shape of the outer surface of the needle tube 1, and the connecting portion 412 is communicated between the notch and the wrapping portion 411.

[0055] Specifically, as shown in Figure 5 , 6 the cross-section of the wrapping portion 411 is consistent with part of the cross-section of the needle tube 1, the inner surface of the wrapping portion 411 is attached to the fixed portion 12 of the needle tube 1, the inner diameter of the wrapping portion 411 is less than or equal to the outer diameter of the needle tube 1, and the inner diameter of the connecting portion 412 is less than the inner diameter of the wrapping portion 411. The connecting portion 412 does not match the surface of the needle tube 1, and the connecting portion 412 forms a certain cavity, so that the needle tube 1 in the wrapping portion 411 is at a certain distance from the notch, and the inner diameter of the connecting portion 412 is smaller than the outer diameter of the needle tube 1, preventing the needle tube 1 from directly separating from the second accommodating groove 410 during transportation vibration and the like. Further, the width of the notch of the second accommodating groove 410 is less than one half of the outer diameter of the needle tube 1, the connecting portion 412 extends from the wrapping portion 411 to the notch in a direction in which the inner diameter gradually decreases.

[0056] The above-mentioned first accommodating member 200 and second accommodating member 400 can be combined and arranged. In the depth direction of the box body 100 or in the width and length direction of the box body 100, the first accommodating member 200 and the second accommodating member 400 can be arranged side by side. In some special cases, the second accommodating member 400 can replace the support table 300 to fix the fixed portion 12 of the needle tube 1 on both sides of the first accommodating member 200. The support member can also be provided with only one type of accommodating member, and the first accommodating groove 210 and the second accommodating groove 410 are arranged at different positions of the accommodating member, and the accommodating member is composed of different materials.

[0057] It can be understood that the width of the first accommodating member 200 and the second accommodating member 400 is not more than the length of the needle tube 1. The first accommodating member 200 and the second accommodating member 400 are integrally formed in the box body 100, or are fixed in the inner wall of the box body 100 by clamping or bonding.

[0058] In one of the embodiments, the packaging box further comprises a cover (not shown in the figure), which is movably connected with the box body 100 and used for closing the opening. The movable connection between the cover and the box body 100 includes, but is not limited to, pivoting and sliding connection. The edge of the cover is provided with a sealing structure. After the cover is connected with the box body 100, the opening is closed, the accommodating space 110 is sealed, and the external dust is prevented from entering the accommodating space 110 and the needle tube 1.

[0059] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.

[0060] The above-mentioned embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, however, it should not be understood as the limitation of the patent application scope. It should be pointed out that, for the ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
