[0037] In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In some descriptions of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0038] The present application provides an automatic needle distribution mechanism, which can arrange a plurality of microneedles in a radial manner to facilitate the assembly of a subsequent microneedle roller, thereby improving the assembly efficiency.

[0039] Referring to Figure 1 , the automatic needle distribution mechanism comprises a bottom plate 100, a needle distribution disc 200 and a vibration assembly 300.

[0040] The needle distribution disc 200 is provided with a loading groove 210 for loading the microneedles, and the bottom of the loading groove 210 is provided with at least one set of radial needle distribution groove structures 220. Specifically, when the microneedles in the loading groove 210 fall into the needle distribution groove structures 220 respectively, the needle distribution groove structures 220 can make the microneedles be distributed in a radial manner.

[0041] The vibration assembly 300 is arranged on the bottom plate, and the vibration assembly 300 is drivingly connected with the needle distribution disc 200, so that the needle distribution disc 200 can vibrate, thereby enabling the microneedles in the loading groove 210 to fall into the needle distribution groove structures 220 respectively.

[0042] In use, a plurality of microneedles can be loaded into the loading groove 210, and then the vibration assembly 300 drives the needle distribution disc 200 to vibrate, so that the microneedles in the loading groove 210 fall into the needle distribution groove structures 220 under the action of vibration. Since the needle distribution groove structures 220 are radial, the microneedles can be distributed in a radial manner after falling into the needle distribution groove structures 220.

[0043] That is, in the automatic needle distribution mechanism of the present application, the radial needle distribution groove structures 220 are arranged in the loading groove 210 of the needle distribution disc 200. When a plurality of microneedles are loaded into the loading groove 210, the vibration assembly 300 drives the needle distribution disc 200 to vibrate, so that the microneedles in the loading groove 210 can fall into the needle distribution groove structures 220 under the action of vibration. When the needle distribution groove structures 220 are filled with microneedles, the microneedles can be distributed in a radial manner, thereby facilitating the subsequent assembly of the microneedle roller.

[0044] Specifically, in an embodiment, each needle distribution groove structure 220 can include a plurality of limiting grooves 221 arranged at the bottom of the needle distribution disc 200, and the plurality of limiting grooves 221 are distributed in a radial manner. Each limiting groove 221 can accommodate a microneedle.

[0045] It can be understood that the plurality of microneedles in the loading groove 210 can fall into each limiting groove 221 under the action of vibration of the vibration assembly 300. When the plurality of limiting grooves 221 are all filled with microneedles, the microneedles can be distributed in a radial manner.

[0046] Referring to Figure 2 , the needle distribution groove structure 220 can also include a mounting hole 222 and a stand (not labeled in the figure). The stand can be detachably arranged in the mounting hole 222. The plurality of limiting grooves 221 are distributed in a radial manner along the outer circumferential direction of the mounting hole 222, and one end of the limiting groove 221 communicates with the mounting hole 222.

[0047] It can be understood that, since one end of the limiting groove 221 is in communication with the mounting hole 222, when a column is installed in the mounting hole 222, the column can be used to position the end of the limiting groove 221 in communication with the mounting hole 222, so that the microneedle falling into the limiting groove 221 can be positioned to ensure the position of the microneedle in the limiting groove 221. In addition, by replacing columns of different diameters, microneedles of different lengths can be loaded into the limiting groove 221, so that the needle arrangement mechanism can arrange microneedles of different lengths.

[0048] For example, when the microneedle is relatively long, a column with a smaller diameter can be selected. When the microneedle is relatively short, a column with a larger diameter can be selected.

[0049] Further, in order to facilitate the stability of the detachable connection of the column with the mounting hole 222, and at the same time enable the column to cooperate with the limiting groove 221 to position microneedles of different lengths, the column can include a first column body and a second column body disposed on the first column body and coaxial with the first column body. The first column body is detachably disposed in the mounting hole 222, and the end surface of the first column body is lower than the bottom surface of the limiting groove 221 in the mounting hole 222. The second column body is used to position the microneedle falling into the limiting groove 221 at one end of the limiting groove 221.

[0050] Specifically, the first column body can be disposed in the mounting hole 222 by means of insertion.

[0051] It can be understood that, in the above manner, by replacing columns of different diameters of the second column body, the limiting groove 221 can limit microneedles of different lengths.

[0052] Referring to Figure 3 In an embodiment, the vibration assembly 300 can include a mounting seat 310, a moving structure 320, and a vibration driving structure 330. The mounting seat 310 is disposed on the bottom plate 100, the needle arrangement disc 200 is movably disposed on the mounting seat 310 through the moving structure 320, and the vibration driving structure 330 is drivingly connected with the moving structure 320 to enable the moving structure 320 to drive the needle arrangement disc 200 to move relative to the mounting seat 310, so that the microneedle in the needle arrangement disc 200 can fall into the needle arrangement groove structure 220.

[0053] Referring to Figure 4In an embodiment, the moving structure 320 can include a first moving piece 321 and a second moving piece 322. The first moving piece 321 is movably arranged on the mounting base 310 along a first horizontal direction, and the second moving piece 322 is movably arranged on the first moving piece 321 along a second horizontal direction. The needle cloth disc 200 is connected to the second moving piece 322, and the vibration driving structure 330 is drivingly connected to the first moving piece 321 and the second moving piece 322, respectively. The first horizontal direction and the second horizontal direction are perpendicular to each other. It can be understood that in this way, the needle cloth disc 200 can be moved along the first horizontal direction and the second horizontal direction, so that the microneedles can fall into the limiting grooves 221.

[0054] Further, in an embodiment, the vibration driving structure 330 can be arranged at an end of the mounting base 310 away from the first moving piece 321. The mounting base 310 and the first moving piece 321 are respectively provided with an empty hole 340. The vibration driving structure 330 is connected to the first moving piece 321 and the second moving piece 322 through the empty holes 340, respectively. It can be understood that in this way, the needle cloth disc 200 can be moved by driving the first moving piece 321 and the second moving piece 322 to move, so that the microneedles can fall into the limiting grooves 221.

[0055] Referring to Figure 4 , the vibration driving structure 330 can include a rotating driving piece 331, a transmission wheel 332, and a first transmission piece 333. The rotating driving piece 331 is drivingly connected to the transmission wheel 332, and the transmission wheel 332 is coaxial with the rotating shaft of the rotating driving piece 331. The first transmission piece 333 is arranged between the first moving piece 321 and the second moving piece 322, and the first transmission piece 333 is arranged on the first moving piece 321. The first transmission piece 333 is provided with a first transmission hole 334 extending along the first horizontal direction. The second moving piece 322 is provided with a second transmission hole 335. The transmission wheel 332 extends along the vertical direction to be located in the first transmission hole 334 and the second transmission hole 335 in sequence. The outer circumferential surface of the transmission wheel 332 can abut against two side surfaces of the first transmission hole 334 arranged opposite along the second horizontal direction, and the outer circumferential surface of the transmission wheel 332 can abut against the inner circumferential surface of the second transmission hole 335.

[0056] Specifically, when the rotating driving member 331 drives the transmission wheel 332 to rotate, the transmission wheel 332 can firstly move along the first horizontal direction in the first transmission hole 334 in the first transmission member 333 while driving the first transmission member 333 to move along the second horizontal direction, that is, the rotating movement of the transmission wheel 332 can be converted into the movement of the transmission wheel 332 along the first horizontal direction in the first transmission hole 334 and the movement of the first transmission member 333 along the second horizontal direction under the action of the first transmission hole 334 of the first transmission member 333, the first transmission member 333 can drive the first moving member 321 to move along the second horizontal direction, and in addition, since the transmission wheel 332 is also located in the second transmission hole 335 of the second moving member 322, when the transmission wheel 332 moves along the first horizontal direction in the first transmission hole 334, the second moving member 322 can be driven to move along the first horizontal direction.

[0057] It can be seen that the above embodiment can make the first moving member 321 move along the second horizontal direction while the second moving member 322 can move along the first horizontal direction, that is, the cloth needle disc 200 can be made to move along the first horizontal direction and the second horizontal direction at the same time, that is, the cloth needle disc 200 can be made to vibrate, and since the rotating driving member 331 can drive the transmission wheel 332 to rotate quickly, the cloth needle disc 200 can be made to vibrate quickly.

[0058] Further, referring to Figure 5 , the vibration driving structure 330 can further include a second transmission member 336, one end of the second transmission member 336 is connected with the driving end of the rotating driving member 331, and the other end of the second transmission member 336 is rotationally connected with the transmission wheel 332.

[0059] It can be understood that the second transmission member 336 can facilitate the rotation of the wheel and make the rotation axis of the wheel different from that of the rotating driving member 331.

[0060] Referring to Figure 4 , the vibration assembly 300 can further include a first sliding rail 350 and a second sliding rail 360. The first moving member 321 is slidably arranged on the mounting seat 310 through the first sliding rail 350, and the first sliding rail 350 can form a first mounting space between the first moving member 321 and the mounting seat 310, and the second transmission member 336 is arranged in the first mounting space.

[0061] The second moving member 322 is slidably arranged on the first moving member 321 through the second sliding rail 360, and the second sliding rail 360 forms a second mounting space between the first moving member 321 and the second moving member 322, and the first transmission member 333 is arranged in the second mounting space.

[0062] It can be understood that the above structure can facilitate the movement of the first moving member 321 and the second moving member 322, and can form a first installation space to facilitate the arrangement of the second transmission member 336, and can form a second installation space to facilitate the arrangement of the first transmission member 333.

[0063] The above only is the preferred embodiment of the utility model, and does not use to limit the utility model, and any modification, equivalent replacement and improvement etc. that are made within the spirit and principle of some utility model should be contained in the protection scope of some utility model.
