Method for combining multiple brow-streaking needles into a whole

Because the needles are not easy to align, this spot welding combination method is very time-consuming and laborious during assembly and processing, and it is easy to damage the aligned needle groups during spot welding, resulting in unevenness. Such uneven and defective products will be patterned in the future. During eyebrow surgery, it will lead to uneven depth of tattooed parts and seriously affect the quality of tattooed eyebrows; the combination method of stainless steel tube clamping method is to put the long and short needles close to each other and cover them with a hollow steel sleeve, and place the needle group horizontally. Apply tight pressure to the appropriate position of the sleeve to set up a ring groove to fix the needle group. Before clamping, the needle group must be placed horizontally by manual holding. During the clamping process, due to punching force or human touch As a result, the tips of the neatly placed needle groups are skewed and uneven, which affects the quality of eyebrow tattoos, and the multi-needle groups combined in this clamping way, due to their structure, are not suitable for use in multiple applications. In case of needle group (more than three needles), the needle on the inner edge cannot be reliably clamped

[0003] Taiwan Patent Publication No. 304872 "Multi-needle Combination Method for Eyebrow Tattoo Needles" (No. 85109786) invention patent, which discloses that holes with different apertures are set on the copper plate base, and a hollow copper sleeve is used to form a fixing device to place multiple needles In the method of grouping, the drilling holes of the copper plate base and the hollow copper sleeve do not penetrate through, which makes the processing very time-consuming and labor-intensive, and the whole is bulky and prone to copper rust, which affects the hygiene of the needle group; moreover, the base and copper for the fixing After the casing is heated in the oven, it becomes hot due to heat conduction, and cannot be taken out immediately for the next step of processing. Therefore, the entire manufacturing process of the eyebrow tattoo needle set takes longer; in this invention, it is also disclosed that the use of Quick-drying glue (such as instant adhesive) strengthens the method of fixing the needle group to replace the aforementioned spot welding combination method and stainless steel pipe clamping method, but the bonding effect of the quick-drying glue is inserted in the multi-pin group that does not penetrate the copper plate base. During the seat, since the multi-needle group is densely inserted into the hollow copper sleeve, and the copper sleeve is in the hole seat of the copper plate base, a good capillary action is formed between them, so it is very easy for the quick-drying glue to penetrate into the multi-needle group and the Between the inner wall of the copper sleeve and the outer wall of the copper sleeve and the inner hole of the hole seat of the copper plate base, the multi-needle group cannot be removed immediately, or the copper sleeve forms a drawback that cannot be processed quickly on a large number of production lines, which is not creative and practical Industrially Available Methods

Moreover, under the high vibration of the eyebrow tattooing machine, the multi-needle group bonded with quick-drying glue is easy to loosen, and the adhesive is easy to decompose when the temperature is above 80°C. Therefore, the method of this invention patent is not firm enough to bond, and its defect rate is high. No less, the production cost is higher, and this method is not practical

[0004] It is obvious that there are many defects in the method of combining multiple needles into one eyebrow tattoo needle in the prior art, and the present invention is mainly aimed at the difficulty in shaping the process, mass production and guarantee Invented due to shortcomings such as poor quality and the inability to reduce production costs
