[0032] In the related art, micro-needle holes are formed in a micro-needle mold. A micro-needle vacuum processing device adds a micro-needle stock solution into the micro-needle holes, and the micro-needle stock solution solidifies in the micro-needle holes to obtain micro-needles. In the existing micro-needle vacuum processing device, the micro-needle mold is processed in a chamber filled with air. Since the micro-needle holes are pointed and the size of the micro-needle holes is small, it is difficult to discharge the air in the micro-needle holes. The micro-needles formed in the micro-needle holes usually have a lot of bubbles, resulting in poor quality of the micro-needles.

[0033] Please refer to Figures 1 to 3 , Figure 1 which is a schematic perspective view of a micro-needle vacuum processing device 100 provided by an embodiment of the present utility model, Figure 2 and Figure 1 is a schematic perspective view of a micro-needle processing device 10 of the micro-needle vacuum processing device 100.

An embodiment of the present utility model provides a micro-needle vacuum processing device 100, which can be applied to the processing of micro-needles in the medical or beauty fields. The micro-needle vacuum processing device 100 includes a micro-needle processing device 10, a loading and unloading device 20, a closing mechanism 30, and a vacuum pumping device 40. The micro-needle processing device 10 is provided with a cavity 101, and the cavity 101 has an opening 102. The loading and unloading device 20 is arranged on one side of the micro-needle processing device 10 and is opposite to the opening 102. The loading and unloading device 20 is used to carry the micro-needle mold 200, and send the micro-needle mold 200 into the cavity 101 from the opening 102, and / or send the micro-needle mold 200 from the opening 102 to the next working station. The closing mechanism 30 is arranged on the micro-needle processing device 10, and the closing mechanism 30 can move relative to the micro-needle processing device 10 to close or open the opening 102. The vacuum pumping device 40 is communicated with the cavity 101, and the vacuum pumping device 40 is used to pump the cavity 101 to a vacuum.

[0034] In this embodiment, the opening 102 includes a feed inlet 1021 and a discharge outlet 1022. The feed inlet 1021 and the discharge outlet 1022 are respectively arranged on the opposite sides of the microneedle processing device 10. The loading and unloading device 20 includes a loading mechanism 21 and an unloading mechanism 22. The loading mechanism 21 is correspondingly arranged with the feed inlet 1021, and the unloading mechanism 22 is correspondingly arranged with the discharge outlet 1022. The loading and unloading process is as follows: The microneedle mold 200 to be processed is added to the loading mechanism 21, and the loading mechanism 21 feeds the microneedle mold 200 to be processed into the cavity 101 through the feed inlet 1021. After the microneedle processing device 10 finishes processing the microneedle mold 200, the processed microneedle mold 200 is conveyed by the microneedle processing device 10 to the discharge outlet 1022, and the processed microneedle mold 200 is sent to the next working station through the unloading mechanism 22 at the discharge outlet 1022. Specifically, both the loading mechanism 21 and the unloading mechanism 22 are linear conveying mechanisms, and the loading mechanism 21 and the unloading mechanism 22 can convey the microneedle mold 200 in a linear direction.

[0035] In other embodiments, the feed inlet 1021 and the discharge outlet 1022 can be integrated, that is, the microneedle processing device 10 completes loading and unloading through the opening 102. The loading and unloading device 20 feeds the microneedle mold 200 to be processed into the cavity 101 through the opening 102, and sends the processed microneedle mold 200 to the opening 102 to the next working station.

[0036] In this embodiment, a first air nozzle 13 and a second air nozzle 14 are provided on the bottom side of the microneedle processing device 10. Both the first air nozzle 13 and the second air nozzle 14 are communicated with the cavity 101. The vacuum pumping device 40 includes a third air nozzle 41 and a fourth air nozzle 42. The third air nozzle 41 is communicated with the first air nozzle 13. The third air nozzle 41 is used for the vacuum pumping device 40 to pump out the air in the cavity 101 of the microneedle processing device 10. The fourth air nozzle 42 is connected to the workshop exhaust system and is used for discharging the air pumped out of the cavity 101 of the microneedle processing device 10. The second air nozzle 14 is connected to the filtration system and is used for breaking the vacuum in the cavity 101 of the microneedle processing device 10. It should be noted that the microneedle processing device 10 has a vacuum requirement when processing the microneedle mold 200, and at this time, the vacuum pumping device 40 needs to pump the cavity 101 to vacuum. When the microneedle mold 200 needs to be conveyed to the discharge outlet 1022 after processing, or when the microneedle mold 200 to be processed needs to enter the cavity 101 through the feed inlet 1021, the microneedle processing device 10 has no vacuum requirement, and at this time, the second air nozzle 14 needs to break the vacuum.

[0037] In this embodiment, the microneedle processing device 10, the loading and unloading device 20, and the vacuum pumping device 40 are all arranged on a support surface (not shown), and the support surface can be selected as the ground or the surface of other equipment. The microneedle mold 200 is provided with microneedle holes (not shown) arranged in an array, and the microneedle holes can be filled with microneedle stock solution by the microneedle processing device 10, and the microneedle stock solution is cured to obtain microneedles corresponding to the shape of the microneedle holes. The microneedle stock solution can be selected as materials with cosmetic effects such as hyaluronic acid, and the microneedle stock solution can also be selected as some materials with medical effects.

[0038] It can be understood that when it is necessary to evacuate the cavity 101, the cavity 101 needs to be in a sealed state, and the closing mechanism 30 can move relative to the microneedle processing device 10 to close the opening 102, thereby forming a sealed cavity 101. After breaking the vacuum in the cavity 101, when the loading and unloading device 20 needs to send the microneedle mold 200 to be processed into the cavity 101 through the opening 102, or send out the microneedle mold 200 that has completed processing from the cavity 101, the opening 102 needs to be in an open state, and the closing mechanism 30 can move relative to the microneedle processing device 10 to open the opening 102, so as to meet the conditions for loading and unloading. In this embodiment, closing mechanisms 30 are provided at both the feed inlet 1021 and the discharge outlet 1022 to facilitate closing or opening the feed inlet 1021 and the discharge outlet 1022.

[0039] By providing the closing mechanism 30 and the vacuum pumping device 40, the closing mechanism 30 can close the opening 102 of the cavity 101, and the vacuum pumping device 40 evacuates the cavity 101, so that the microneedle mold 200 can be processed in a vacuum environment to reduce the bubbles in the microneedles formed on the microneedle mold 200, thereby improving the quality of the microneedles.

By providing the slidably connected first baffle 321 and second baffle 322, the second baffle 322 can avoid the microneedle processing device 10 under the drive of the second driving member 312 to prevent interference between the second baffle 322 and the microneedle processing device 10.

[0043] In an embodiment of this embodiment, please refer to Figures 1 to 3 , the second driving member 312 is installed on the second baffle 322 and is connected to the first baffle 321.
