[0002] Cosmetic injections, as an auxiliary medical tool, are now widely used in the medical aesthetics industry.
[0003] After the cosmetic needles are manufactured, they need to be clamped into a special product box, also known as a needle storage box. Due to the requirements of the medical industry, the cosmetic needles must be kept free from any accidental contact throughout the entire process. This means that within the storage box, the cosmetic needles cannot easily shake or experience other unstable installation during transport; ideally, they should be kept in a vertical, precise, and stable position when assembled within the storage box. However, because cosmetic needles are extremely thin, the assembly and clamping of them has become a significant challenge in the current production process. Utility Model Content

Detailed Implementation
[0024] The present invention will be further described below with reference to specific embodiments.
[0025] like Figures 1-6 As shown, the cosmetic needle auxiliary clamping device of this utility model includes a needle suction assembly 1, a needle guide assembly 2, and a delivery assembly 3.
[0026] The needle suction assembly 1 includes a needle suction block 11 that can move up, down, forward, backward, left, and right. Specifically, it can move along three axes by using multiple guide rails and motors. The needle suction block 11 is cubic in shape, with three vertical needle suction grooves 12 on one of its shorter sides. The bottom of each groove 12 is rectangular, gradually widening outwards on both sides. This shape allows it to hold different sizes of cosmetic needles. Several air holes 13, connected to an external air source, are also provided on the bottom surface of the needle suction grooves 12. These air holes 13 are arranged in a straight line to ensure sufficient suction.
[0027] The guide needle assembly 2 includes a vertically movable mounting plate 21, which can move up and down via guide rails and a motor. At the front end of the mounting plate 21, there is a guide needle block 22, the top surface of which is flush with the top surface of the mounting plate 21. Its geometric shape is also cubic. Nine guide needle holes 23 are formed from top to bottom on the guide needle block 22, arranged in a three-by-three array. The spacing between each row of guide needle holes 23 corresponds to the three needle suction slots 12. The diameter of the guide needle holes 23 gradually decreases from top to bottom and gradually increases again near the bottom. This design prevents the cosmetic needle from easily tilting during clamping, further improving stability. In actual use, the diameter of the guide needle holes 23 can be almost identical to the thickness of the cosmetic needle, preventing it from easily falling out. Clamping is further achieved by the micro-vibration motor 24 provided in the guide needle assembly 2.
[0028] Specifically, the micro-vibration motor 24 is positioned behind the guide needle block 22, and to further enhance the micro-vibration effect, the micro-vibration motor 24 is positioned as close as possible to the guide needle block 22. An eccentric block 25 is located at the end of the output shaft of the micro-vibration motor 24, situated at the top of the mounting plate 21, while the entire micro-vibration motor 24 is positioned at the bottom of the mounting plate 21. The eccentric block 25 provides the micro-vibration effect. In this embodiment, the micro-vibration motor 24 operates at a speed of 9 rpm and a voltage of 12V. The placement of the micro-vibration motor 24 ensures that all the cosmetic needles are positioned at a uniform height, maintaining the needle tips on the same horizontal plane and preventing unevenness during assembly.
[0029] The delivery assembly 3 includes a linear track 31, on which a fixed plate 32 is slidably arranged. Several needle storage boxes 33 are arranged side by side on the fixed plate 32. The needle storage boxes 33 are provided with needle storage holes 34 corresponding to the position, shape and size of the needle guide holes 23. At the same time, the needle storage boxes 33 can also accommodate needle guide blocks 22.
[0030] The working principle of this utility model is as follows:
[0031] First, the operator moves the suction block 11 and uses the air vent 13 to create a vacuum, adsorbing three beauty needles into the suction slot 12. Simultaneously, the operator controls the feeding component 3 to move the needle storage box 33 to the preset clamping position. Then, the operator controls the guide component 2 to move the guide block 22 directly above the needle storage box 33 and moves it downwards so that its bottom falls onto the box, aligning the guide holes 23 with the storage holes 34. Next, the operator moves the suction block 11 directly above the guide block 22, and the air vent 13 releases, allowing the three beauty needles to fall into the three parallel guide holes 23. Because the diameter of the guide holes 23 is gradually narrowing, the beauty needles will not deviate from the guide holes 23 when falling. Furthermore, due to the design of the aperture being close to the beauty needle's diameter, the three beauty needles will be secured in the middle of the guide holes 23. Once all nine beauty needles are inserted into the guide needle hole 23, the micro-vibration motor 24 is activated, causing the nine beauty needles to gradually pass through the center of the guide needle hole 23 in a vertical state under the action of micro-vibration, and finally fall accurately into the needle storage hole 34. Then, the guide needle block 22 is controlled to rise and detach from the beauty needles. The needle storage box 33 moves forward, and the next needle storage box 33 arrives at the preset clamping position to begin the assembly of the next set of beauty needles.
