[0002] There are two existing methods for manufacturing false eyelashes. One is to braid long fibers and then create the tips of the eyelashes. The false eyelashes manufactured by this method are not realistic enough. The other manufacturing method is to arrange the fibers with tips in a mold. The false eyelashes manufactured by this method are more realistic, but it depends on manual labor. The grasping and arranging of fibers is a delicate task that relies on a large number of young female workers. With the shortage of labor force, it is necessary to automate the fiber grasping and arranging process.

[0003] The artificial fibers for manufacturing false eyelashes have a cross-sectional shape approximately as a rounded rectangle and a circle, with a length of 20 - 30 mm and a diameter of 50 - 100 mm.

[0004] Due to the small size, softness of the fibers and high precision requirements for arrangement, it is very difficult for automated equipment to achieve grasping and arranging. It is difficult for traditional mechanical structures such as vacuum suction cups and pneumatic clamps to achieve the grasping and arranging of fine fibers. Summary of the Utility Model

Detailed Embodiments

[0033] In view of the deficiencies in the prior art, the inventors of this case have, through long-term research and a large number of practices, been able to propose the technical solution of the present utility model. The following will further explain the technical solution, its implementation process and principle, etc.

[0034] A grasping mold for grasping ultrafine fibers, comprising: a mold body, on a selected working surface of the mold body, at least one first microgroove structure is provided. Preferably, a plurality of the first microgroove structures are provided on the selected working surface of the mold body, and the plurality of first microgroove structures are arranged in sequence along a selected direction, which can improve the efficiency of grasping ultrafine fibers.

[0035] On the groove wall of the first microgroove structure, a second microgroove structure is provided. Preferably, the second microgroove structure is correspondingly arranged at the bottom of the first microgroove structure, and is used to prevent liquid from overflowing the first microgroove and sticking multiple fibers.

[0036] On the groove wall of the second microgroove structure, a microstructure is provided. The microstructure is used to confine the liquid droplet within the second microgroove structure. The ultrafine fibers located within the first microgroove-like structure can contact the liquid droplet within the second microgroove structure and be adsorbed and fixed by the liquid droplet. There is always liquid within the second microgroove structure 3 during the processing of ultrafine fibers. The liquid within the second microgroove structure 3 can be water, ethanol, carbon tetrachloride, silicone oil, etc.

[0037] Using the surface tension of the liquid to grasp fine fibers replaces the traditional method of using a large amount of labor to grasp and arrange fine fibers, saving a large amount of labor, improving the grasping efficiency, and also improving the consistency of fiber grasping. Specifically, the microstructure includes a microfluidic device. The microfluidic device includes a liquid microcontainer. The liquid microcontainer includes microgrooves or micropores. The liquid is transferred to the second microgroove through microporous template printing. Strictly controlling the amount of liquid dropped from the liquid microcontainer into the second microgroove is the key to successfully grasping a single fiber. If too much liquid is dropped into the second microgroove, the liquid will overflow; if too little is dropped, the fiber cannot be grasped.

[0038] The first microgroove structure allows a single ultrafine fiber to enter in a selected posture, and can realize the separation of single fibers. The first microgroove structure 2 can be square, rectangular or semi-circular. The shape of the first microgroove structure 2 is preferably semi-circular. The diameter of the first microgroove structure 2 is 0.05 - 0.1 mm. The diameter of the first microgroove structure 2 is set according to the diameter of the fiber. The length of the first microgroove structure 2 is 10 - 50 mm. The length of the first microgroove structure 2 is set according to the length of the fiber.

[0039] The present utility model also discloses an ultra-fine fiber transfer device, which includes a grasping die and a driving mechanism. The driving mechanism is in transmission connection with the grasping die and is used to drive the grasping die to translate and / or rotate, and finally to drive the grasping die to move into a container for placing ultra-fine fibers. Specifically, the driving mechanism can be a linear driving mechanism, which can drive the grasping die to move in the XY plane or the XZ plane or the YZ plane. For example, the linear driving mechanism can be a cylinder or a motor. The driving mechanism can also be a linear driving mechanism and a rotary driving mechanism, which can drive the grasping die to rotate around the X or Y or Z axis and perform a linear motion. For example, the driving mechanism can be a rotary cylinder and a linear cylinder, and the linear cylinder is arranged on the driving shaft of the rotary cylinder. In addition, the driving mechanism can also be a three-dimensional displacement platform, as long as it can drive the grasping die to move into the fiber container.

[0040] The present utility model also discloses an ultra-fine fiber transfer system, which includes a transfer device and a fiber container. A cavity for placing a plurality of ultra-fine fibers is arranged inside the fiber container 300. Before making false eyelashes, a plurality of extremely fine fibers are densely arranged in the same direction in the cavity of the fiber container 300. Driven by the driving mechanism 200, the grasping die 100 extends into the fiber container 300 to grasp ultra-fine fibers or moves out from the fiber solution. A cover plate for covering the opening is arranged at the opening of the fiber container. The cover plate can be opened or closed relative to the fiber container. A power mechanism for driving the cover plate to open or close relative to the fiber container is arranged on one side of the cover plate. The cover plate 11 can be hinged to the fiber container 300 or slidably connected to the fiber container 300. Of course, when the cover plate 11 is to be opened or closed, the grasping die 100 is in the upper position, that is, the driving mechanism 200 drives the grasping die 100 away from the fiber container 300. In this embodiment, the cover plate 11 is slidably connected to the fiber container 300 through a linear guide rail. The power mechanism can be a cylinder, a motor-driven lead screw or a motor-driven gear 9 and rack 10.

[0041] On the above basis, a rotary power mechanism for driving the fiber container to rotate is arranged on one side of the fiber container. The rotary power mechanism is used to drive the fiber container 300 to rotate so that the fiber tips face downward to achieve consistent tip heights. The rotary power mechanism can be a cylinder or an electric cylinder. A vibration mechanism is arranged on one side of the fiber container. The vibration mechanism vibrates when the fiber tips face downward to promote consistent fiber tip heights. The vibration mechanism can be arranged inside the fiber container 300 or outside the fiber container 300. In this embodiment, the vibration mechanism is arranged inside the fiber container 300 and at the inner bottom end of the fiber container 300. A partition 5 is used to separate the cavity for placing fibers from the vibration mechanism. More specifically, the vibration mechanism can be a vibration motor 6 or a vibrator. In this embodiment, the vibration mechanism selects the vibration motor 6.

[0042] In some embodiments, a visual inspection mechanism for detecting whether the first microgroove structures 2 are filled with fibers is provided on one side of the grasping die 100. The visual inspection mechanism is used to detect whether each first microgroove structure 2 of the grasping die 100 is filled with fibers. The visual inspection mechanism can be an industrial camera or a sensor. In this embodiment, the visual inspection mechanism is a sensor. The ultra-fine fiber transfer system further includes a control mechanism, and the visual inspection mechanism, the driving mechanism 200, and the power mechanism are electrically connected to the control mechanism respectively.

[0043] To achieve dense and light-impermeable fiber roots, on the one hand, the lengths of the fibers need to be basically the same, and on the other hand, the fibers need to be closely arranged without root defects. Therefore, a visual inspection mechanism is required to detect each first microgroove structure 2 in the grasping die 100 to detect whether there are fibers in each first microgroove structure 2. When the visual inspection mechanism detects that there are no fibers in the first microgroove structure 2 in the grasping die 100, it sends a signal to the control mechanism, and the control mechanism controls the driving mechanism 200 to drive the grasping die 100 to press into the fiber container 300 to grasp the fibers at the missing positions until there are fibers in all the first microgroove structures 2.

A driving cylinder 4 for driving the grasping die to move linearly is arranged on one side of the grasping die 100. A partition 5 is arranged in the fiber container 300, dividing the inner cavity of the fiber container 300 into two spaces, namely an upper cavity and a lower cavity. Two vibration motors 6 are arranged in the lower cavity. The upper space is a cavity for placing superfine fibers. The upper end of the fiber container 300 is fixedly connected with a biaxial motor 7. Two driving ends of the biaxial motor 7 are respectively connected with transmission shafts 8. A gear 9 is connected to each transmission shaft 8. One side of the gear 9 is meshed with a rack 10. A cover plate 11 is fixedly connected to the rack 10. The two racks 10 are symmetrically arranged inside the fiber container 300, and both of the two racks 10 are fixedly connected with the cover plate 11. When the cover plate 11 needs to be closed, the biaxial motor 7 drives the gear 9 to rotate, thereby driving the rack 10 to move, and then driving the cover plate 11 to move towards the direction close to the fiber container 300 until the cover plate 11 covers the opening of the fiber container 300. When the cover plate 11 needs to be opened, the biaxial motor 7 drives the gear 9 to rotate, thereby driving the rack 10 to move, and then driving the cover plate 11 to move away from the fiber container 300 until the opening of the fiber container 300 is opened to the required size.

[0050] A cylinder is arranged below the fiber container 300. The driving end of the cylinder is hinged to the bottom of the fiber container 300. The cylinder is arranged obliquely to the bottom of the fiber cylinder.
