Description

Technical Field

[0001] The present application relates to the technical field of microneedle production, and in particular to a stacked microneedle mold tray. Background Art

[0002] Microneedle is a newer transdermal drug delivery device, generally composed of a group of 25 to 2000 μm long needle tips arranged on a base. It achieves the purpose of minimally invasive and painless drug delivery by piercing the stratum corneum of the skin. Microneedle technology has received more and more attention in beauty and has been widely used, especially in microcrystalline eye patches. The main microneedle mold materials are currently stainless steel, PDMS, etc. PDMS has certain advantages in the preparation of microneedle patches because of its low adhesion to the microneedle membrane and easy separation.

[0003] A Chinese patent with announcement number CN208697785U discloses a mold for preparing a microneedle membrane, which consists of a whole negative mold. The negative mold has a geometric groove for loading the solution for preparing the microneedle membrane, which is convenient for one-time infusion; there is a microneedle array at the bottom of the groove, and the microneedle array is at a certain distance from the side plate of the negative mold to facilitate the peeling of the microneedle membrane; the side plate of the mold has a certain width for easy handholding.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0005] Since the size of the microneedle mold itself is relatively small, generally the length and width of each mold are about 10 cm. When automating the production of microneedle products, a large number of microneedle molds need to be transferred using conveyor belts or robotic arms. If the microneedle molds are only transported one at a time, not only is the work efficiency low, but the microneedle mold is also easily damaged during transfer, which is not conducive to the repeated and long-term use of the microneedle mold. Utility Model Content

[0006] The present application provides a stacked microneedle mold tray to improve the following technical problems:

[0007] A large number of microneedle molds need to be transferred by means of conveyor belts or robotic arms. If the microneedle molds are only transported one at a time, not only is the work efficiency low, but the microneedle molds are also easily damaged during transfer, which is not conducive to the repeated and long-term use of the microneedle molds.

[0008] The present application provides a stacked microneedle mold tray, which adopts the following technical solution:

[0040] The following is combined with Figure 1-2 This application is described in further detail.

[0041] The present application embodiment discloses a stacked microneedle mold tray. Figure 1 and Figure 2 , the stacked microneedle mold tray includes:

[0042] A support frame 1, in which a plurality of microneedle molds arranged in an array and having a square structure are installed, and a plug hole is provided on the upper surface or the lower surface of the support frame 1;

[0043] The support plate 2 is welded in the support frame 1, and the support plate 2 and the support frame 1 form a square cavity for mounting the microneedle mold; and

[0044] The connection component 3 is installed on the lower surface or the upper surface of the support frame 1 and is used for plugging and assembling with the plug holes of the adjacent support frame 1. The connection component 3 and the plug holes are arranged in a one-to-one correspondence.

[0045] The connecting component 3 and the supporting frame 1 are detachably assembled, and at least three connecting components 3 are provided, and three of the connecting components 3 are arranged in a triangular shape on the supporting frame 1. In the present embodiment, eight connecting components 3 are specifically provided, four of which are located at the four corners of the supporting frame 1, and the other four connecting components 3 are located at the midpoints of the four sides of the supporting frame 1. Through the above technical solution, the upper and lower stacked microneedle mold trays are more stable when stacked.

[0046] The connecting assembly 3 includes a threaded segment 31, a screw cap 32 and a hemispherical end 33. The screw cap 32 is connected between the threaded segment 31 and the hemispherical end 33. The upper surface of the support frame 1 is provided with a threaded hole for threaded assembly of the threaded segment 31. The plug-in hole is provided on the lower surface of the support frame 1. The hemispherical end 33 is used to be inserted into the plug-in hole of the adjacent support frame 1. A convex spherical surface is provided at the end of the hemispherical end 33 away from the screw cap 32.

[0047] The connection assembly 3 designed as above has a firm and simple structure, is easy to install and replace, and is convenient for the hemispherical end 33 to be quickly inserted into the interior of the plug hole.

[0048] The plug-in hole is smaller than the minimum diameter of the screw cap 32. The screw cap 32 is a hexagonal nut. The hexagonal nut is convenient for screwing and installation, and the hexagonal nut can be blocked outside the plug-in hole, thereby ensuring a large height difference between the upper and lower stacked microneedle mold trays, that is, a large gap, which effectively prevents the microneedle mold from being touched and damaged when the stacked microneedle mold trays are stacked.

[0049] A reinforcement plate 11 is provided on the lower surface of the support frame 1 at the plug-in hole. The reinforcement plate 11 and the support frame 1 are integrally formed or welded and fixed. The plug-in hole passes through the reinforcement plate 11. The reinforcement plate 11 can improve the structural strength of the support frame 1 at the plug-in hole, thereby improving the structural strength and service life.

[0050] A plurality of weight-reducing holes 21 are provided on the support plate 2. The diameter of the weight-reducing holes 21 is smaller than the minimum side length of the microneedle mold. The weight-reducing holes 21 can not only reduce the weight of the support plate 2, but also prevent the microneedle mold from falling from the weight-reducing holes 21. The weight-reducing holes 21 also have a water-permeable effect, and can be rinsed and cleaned from both the upper and lower directions when rinsing and cleaning the stacked microneedle mold tray.

[0051] The weight-reducing holes 21 are arranged in a staggered manner in a plum blossom shape on the support plate 2. By adopting the above technical solution, the weight-reducing holes 21 can be designed to be more dense, thereby greatly reducing the weight of the support plate 2, making it easier for the stacked microneedle mold tray to be transported with less energy loss.

[0052] The support frame 1 and the support plate 2 are both rectangular in shape. One of the corners of the support frame 1 is set as a bevel chamfer 12, and the other three corners of the support frame 1 are set as arc chamfers 13. The bevel chamfers 12 and the arc chamfers 13 can prevent the corners of the support frame 1 from being too sharp and injuring people, which is safer. Moreover, the only bevel chamfer 12 is different from the three arc chamfers 13, which is conducive to the equipment and staff to quickly identify whether the stacked microneedle mold tray is placed correctly.

[0053] The implementation principle of a stacked microneedle mold tray in the embodiment of the present application is:

[0054] The support frame 1 has a good barrier and limiting effect on the microneedle molds arranged in an array and in a square structure. The support plate 2 has a good supporting effect on the microneedle molds arranged in an array and in a square structure. In addition, by adding the connecting component 3 and the plug-in hole, it is beneficial to stably stack the upper and lower stacked microneedle mold trays. Multiple microneedle molds can be transported each time, with high work efficiency. The microneedle molds are not easily damaged during transfer, which is beneficial to the repeated and long-term use of the microneedle molds.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
