If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0032] In the related art, the conveying mechanism is conveyed by chains, chain plates, rollers, etc. The conveying mechanism conveys the microneedle mold to be processed to the vacuum chamber of the microneedle processing device for processing, and the conveying mechanism conveys the microneedle mold that has been processed in the vacuum chamber to another place for the next process. In order to meet the vacuum conditions of the vacuum chamber of the microneedle mold, the conveying mechanism is usually a segmented design, that is, the conveying mechanism includes three parts, the first part is located outside the vacuum chamber and is used to transfer the microneedle mold to be processed into the vacuum chamber, the second part is located in the vacuum chamber, the second part is used to dock with the first part, receive the microneedle mold to be processed and transfer the microneedle mold in the vacuum chamber, and the third part is located outside the vacuum chamber, the second part is used to dock with the second part, and is used to transfer the processed microneedle mold to the next process. Although such a design can meet the vacuum processing conditions of the microneedle mold, the design of the conveying mechanism is relatively complicated and the cost is too high. At the same time, the microneedle processing device needs to be provided with a corresponding closed structure to maintain the vacuum, and the structure of the microneedle processing device is also relatively complicated. Moreover, the conveying mechanism usually transmits in a straight line, that is, the first part and the third part are generally located on opposite sides of the microneedle processing device, and the loading position and unloading position of the microneedle mold are located on different sides, which is inconvenient for manual loading and unloading, reducing the processing efficiency.

[0033] See also Figure 1 , Figure 1 : is a schematic diagram of the three-dimensional structure of a microneedle processing device 100 provided by an embodiment of the utility model. The utility model embodiment provides a microneedle processing device 100, which can be applied to microneedle processing in medical or cosmetic aspects. The microneedle processing device 100 includes a base 10, a microneedle processing device 20, a turntable mechanism 30 and a driving mechanism 40. The base 10 is used to be arranged on a support surface. The microneedle processing device 20 is arranged on the base 10 and is provided with a processing chamber 201, and the processing chamber 201 has an opening 2011. The turntable mechanism 30 is installed on the base 10, and the turntable mechanism 30 is provided with a microneedle mold 301. The turntable mechanism 30 can rotate relative to the base 10 so that the microneedle mold 301 corresponds to the opening 2011, so that the microneedle processing device 20 can add the microneedle stock solution to the microneedle mold 301. The driving mechanism 40 is installed on the base 10 and is connected to at least one of the microneedle processing device 20 and the turntable mechanism 30. The driving mechanism 40 is used to drive the microneedle processing device 20 and / or the turntable mechanism 30 to move relative to the base 10 so that the turntable mechanism 30 closes the opening 2011 .

[0034] Specifically, the support surface can be selected as the ground or the surface of other equipment. The microneedle processing device 20 is arranged on the base 10 so as to be relatively movable. The microneedle mold 301 is provided with microneedle holes arranged in an array (not shown), and the microneedle holes can be filled with microneedle stock solution by the microneedle processing device 20, and the microneedle stock solution is solidified to obtain microneedles of a shape corresponding to the microneedle holes. The microneedle stock solution can be selected from materials with cosmetic effects such as hyaluronic acid, and the microneedle stock solution can also be selected from some materials with medical effects.

[0035] It can be understood that the turntable mechanism 30 rotates relative to the base 10, so that the microneedle mold 301 corresponds to the opening 2011, and the microneedle mold 301 to be processed can be processed by the microneedle processing device 20, or the microneedle mold 301 leaves the opening 2011, and the processed microneedle mold 301 can be sent to the next process.

[0036] In some embodiments, the driving mechanism 40 can be connected to the microneedle processing device 20, and the driving mechanism 40 drives the microneedle processing device 20 to move relative to the base 10, so that the microneedle processing device 20 moves toward the turntable mechanism 30, and the turntable mechanism 30 closes the opening 2011, thereby forming a closed processing chamber 201, so that the processing chamber 201 is evacuated, and the microneedle mold 301 is located in the vacuum processing chamber 201 for processing. After the microneedle mold 301 is processed in the vacuum processing chamber 201, the driving mechanism 40 drives the microneedle processing device 20 to move relative to the base 10, so that the microneedle processing device 20 moves away from the turntable mechanism 30, and the turntable mechanism 30 no longer closes the opening 2011, and then the turntable mechanism 30 rotates relative to the base 10 to drive the processed microneedle mold 301 to rotate to the position of the next process.

[0037] In some other embodiments, the driving mechanism 40 can also be connected to the turntable mechanism 30, and the driving mechanism 40 drives the turntable mechanism 30 to move relative to the base 10, so that the turntable mechanism 30 moves toward the microneedle processing device 20, and the turntable mechanism 30 closes the opening 2011, thereby forming a closed processing chamber 201, so that the processing chamber 201 is evacuated, and the microneedle mold 301 is located in the vacuum processing chamber 201 for processing. After the microneedle mold 301 is processed in the vacuum processing chamber 201, the driving mechanism 40 drives the turntable mechanism 30 to move relative to the base 10, so that the turntable mechanism 30 moves away from the microneedle processing device 20, and the turntable mechanism 30 no longer closes the opening 2011, and then the turntable mechanism 30 rotates relative to the base 10 to drive the processed microneedle mold 301 to rotate to the position of the next process.

[0038] In some other embodiments, the driving mechanism 40 can also be connected to the microneedle processing device 20 and the turntable mechanism 30 at the same time. The driving mechanism 40 drives the microneedle processing device 20 and the turntable mechanism 30 to move relative to the base 10, and the microneedle processing device 20 and the turntable mechanism 30 are relatively close to each other, and the turntable mechanism 30 closes the opening 2011, thereby forming a closed processing chamber 201, so that the processing device can be vacuumed, and the microneedle mold 301 is located in the vacuum processing chamber 201 for processing. After the microneedle mold 301 is processed in the vacuum processing chamber 201, the driving mechanism 40 drives the microneedle processing device 20 and the turntable mechanism 30 to move relative to the base 10, so that the microneedle processing device 20 and the turntable mechanism 30 are relatively far away from each other, and the turntable mechanism 30 no longer closes the opening 2011, and then the turntable mechanism 30 rotates relative to the base 10 to drive the processed microneedle mold 301 to rotate to the position of the next process.

[0039] It is understandable that when the microneedle processing device 20 and / or the turntable mechanism 30 moves relative to the base 10, the movement mode can be selected as rotation, movement, or a combination of rotation and movement.

[0040] By setting a turntable mechanism 30 to rotate relative to the base 10, and a driving mechanism 40 driving the microneedle processing device 20 and / or the turntable mechanism 30 to move relative to the base 10, the turntable mechanism 30 and the microneedle processing device 20 can enclose and form a closed processing chamber 201 to meet the vacuum processing conditions. The microneedle processing device 20 does not need to be provided with an additional closed structure, and the turntable mechanism 30 does not need to be provided with multiple ones. The structures of the microneedle processing device 20 and the turntable mechanism 30 are relatively simple. At the same time, the loading position and the unloading position of the microneedle mold 301 can be set on the same side to facilitate manual loading and unloading, thereby improving the processing efficiency.

[0041] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 , Figure 2 yes Figure 1Schematic diagram of the three-dimensional structure of the microneedle processing device 20 and the driving mechanism 40. The driving mechanism 40 includes a lifting driver 41. The lifting driver 41 is installed on the base 10 and connected to the microneedle processing device 20. The lifting driver 41 can drive the microneedle processing device 20 to rise and fall relative to the base 10, so that the microneedle processing device 20 is close to or away from the turntable mechanism 30. Specifically, the lifting driver 41 can be driven by a motor drive, a cylinder drive, a hydraulic cylinder, etc. to drive the microneedle processing device 20. It is understandable that the lifting drive 41 drives the microneedle processing device 20 to rise and fall relative to the base 10, so that the microneedle processing device 20 moves toward the turntable mechanism 30, the turntable mechanism 30 closes the opening 2011, and the microneedle mold 301 to be processed is in the closed processing chamber 201, or the microneedle processing device 20 moves away from the turntable mechanism 30, the turntable mechanism 30 leaves the opening 2011, and the processed microneedle mold 301 leaves the processing chamber 201 and can be transferred to the position of the next process through the turntable mechanism 30. In this way, the processing chamber 201 can be closed, the vacuum processing conditions can be met, and the structure is relatively simple.

[0042] In one embodiment of this implementation, please continue to refer to Figure 1 and Figure 2 , the driving mechanism 40 also includes a first guide structure 42 and a second guide structure 43. The first guide structure 42 is arranged on the microneedle processing device 20, and the second guide structure 43 is arranged on the base 10. The first guide structure 42 and the second guide structure 43 are slidably matched. Specifically, the number of the first guide structure 42 and the second guide structure 43 are both two, and the two groups of guide structures are arranged on opposite sides of the lifting driver 41 to achieve higher precision guidance. In this embodiment, the first guide structure 42 is provided with a guide groove 421, and the second guide mechanism is a guide column fixed on the base 10, and the guidance is achieved by the sliding cooperation between the guide groove 421 and the guide column. In other embodiments, the guide groove 421 can also be provided on the second guide mechanism, and the first guide mechanism is set as a guide column.

[0043] In one embodiment of this implementation, please refer to Figures 1 to 4 , Figure 3 yes Figure 1 A schematic structural diagram of the turntable mechanism 30 and the support structure 12 in the front view direction, Figure 4 yes Figure 3Schematic diagram of the structure of the turntable mechanism 30 and the support structure 12 in the top view direction. The number of microneedle molds 301 is multiple, and the multiple microneedle molds 301 are arranged in a circular array along the rotation axis of the turntable mechanism 30. The turntable mechanism 30 can rotate relative to the base 10 to switch different microneedle molds 301 to correspond to the opening 2011. By setting the number of microneedle molds 301 to multiple, the multiple microneedle molds 301 are arranged in a circular array along the rotation axis of the turntable mechanism 30, and the multiple microneedle molds 301 can correspond to the opening 2011 in sequence, thereby improving the processing efficiency. In this embodiment, the number of microneedle molds 301 is set to two, and the two microneedle molds 301 are arranged symmetrically. In other embodiments, the number of microneedle molds 301 can also be set to three, and the three microneedle molds 301 are arranged in a 120° circular array. In some other embodiments, the number of microneedle molds 301 can also be one, and microneedle processing is performed through one microneedle mold 301.

[0044] In one embodiment of this implementation, please continue to refer to Figures 1 to 4 The turntable mechanism 30 includes a turntable 31 and a rotary driver 32. The rotary driver 32 is mounted on the base 10, and the rotary driver 32 is connected to the turntable 31. The rotary driver 32 can drive the turntable 31 to rotate relative to the base 10. Specifically, the rotary driver 32 can drive the turntable 31 by means of a motor, a cylinder, a hydraulic cylinder, etc. One side of the turntable 31 is connected to the output shaft of the rotary driver 32, and the other side of the turntable 31 is installed with a microneedle mold 301, which can be closed with the opening 2011. The rotary driver 32 is arranged to drive the turntable 31 to rotate, and the microneedle mold 301 is arranged on the side of the turntable 31 facing away from the rotary driver 32, so as to close the opening 2011 of the processing chamber 201 through the turntable 31, and to transport the microneedle mold 301 through the turntable 31.

[0045] In one embodiment of this implementation, please continue to refer to Figures 1 to 4 , the base 10 is provided with a support structure 12, and the support structure 12 abuts against the side of the turntable 31 facing away from the microneedle processing device 20. It can be understood that good contact and greater pressure are required between the microneedle processing device 20 and the turntable 31, so that the turntable 31 can better close the opening 2011 of the processing chamber 201, and the processing chamber 201 can complete the vacuuming step. However, the pressure exerted by the microneedle processing device 20 on the turntable 31 is too large, which can easily damage the turntable 31 and the rotating drive 32. By arranging the support structure 12 on the base 10, the support structure 12 can share the pressure well and reduce the risk of damage to the turntable 31 and the rotating drive 32. At the same time, due to the existence of the support structure 12, there can be greater pressure between the microneedle processing device 20 and the turntable 31, so as to smoothly complete the vacuuming step.

[0046] In one embodiment of this implementation, please continue to refer to Figures 1 to 4 The support structure 12 includes a support block 121 and an abutment block 122. The support block 121 is fixed on the base 10, and the support block 121 is threadedly connected to the abutment block 122, and the abutment block 122 is used to abut against the turntable 31. Specifically, the top of the abutment block 122 can be set as an elastic structure to prevent the abutment block 122 from damaging the turntable 31. By setting the support block 121 and the abutment block 122 to be threadedly connected, the height of the abutment block 122 relative to the base 10 can be adjusted by relative rotation, thereby reducing the risk of insufficient or excessive abutment between the abutment block 122 and the turntable 31.

[0047] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the three-dimensional structure of the microneedle stock solution adder. The microneedle processing device 20 includes a motion mechanism (not shown) and a microneedle stock solution adder 22, and the motion mechanism and the microneedle stock solution adder 22 are both arranged in the processing chamber 201. The motion mechanism can drive the microneedle stock solution adder 22 close to the microneedle mold 301, so that the microneedle stock solution adder 22 can add microneedle stock solution to the microneedle mold 301. Specifically, the motion mechanism has more than two axes of freedom, so that the motion mechanism can drive the microneedle stock solution adder 22 close to the microneedle mold 301, and slide on the microneedle mold 301 to coat different areas of the microneedle mold 301, or move above the microneedle mold 301 to drip liquid on different areas of the microneedle mold 301. Preferably, the microneedle stock solution adder 22 and the motion mechanism are a group, so as to reduce the volume of the processing chamber 201, reduce the difficulty of vacuuming and simplify the structure of the microneedle processing device 20.

[0048] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 and Figure 6 , Figure 6 It is a schematic diagram of the three-dimensional structure of a microneedle processing device provided by an embodiment of the utility model. The microneedle processing device 100 also includes a vacuum device 50. The vacuum device 50 is connected to the microneedle processing device 20, and the vacuum device 50 is used to vacuum the processing chamber 201. Specifically, in the present embodiment, a mounting chamber is provided on the side of the base 10 facing away from the microneedle processing device 20, and the vacuum device 50 is installed in the mounting chamber. In other embodiments, the vacuum device 50 may also be installed at other positions of the base 10, or not installed on the base 10. By providing the vacuum device 50, it is convenient to evacuate the processing device into a vacuum state, which helps to reduce the risk of bubbles generated during microneedle processing.

[0049] In one embodiment of this implementation, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The microneedle processing device 100 further includes a feeding device 60. The feeding device 60 is connected to the microneedle processing device 20, and is used to deliver the microneedle stock solution to the microneedle processing device 20. Specifically, the microneedle stock solution adder 22 is provided with a liquid nozzle 221, and the feeding device 60 is connected to the liquid nozzle 221. The feeding device 60 delivers the microneedle stock solution to the microneedle stock solution adder 22 through the liquid nozzle 221, so that the microneedle stock solution adder 22 adds the microneedle stock solution to the microneedle mold 301.
