Description

Technical Field

[0001] The invention relates to an assembly device, in particular to a hair extension buckle assembly device. Background Art

[0002] Hair extensions are well-known and popular products used to increase the length or volume of an individual's hair while blending into or becoming integral with the wearer's hair. Hair extensions allow the wearer to modify the appearance of their hair by typically adding multiple extensions of a selected length or lengths and color or colors to achieve a desired look.

[0003] like Figure 5 The figure shows a popular nano hair extension buckle. It includes an outer ring 4 and an inner ring 5 positioned within the outer ring. The inner ring 5 is typically made of silicone, which has a certain degree of elasticity. Once inserted into the outer ring 4, the inner ring 5 secures to the outer ring through its own elasticity. To attach the hair, a crochet hook is used to thread the hair through the inner ring 5, which then clamps the hair in place.

[0004] At present, although there are automated assembly equipment for the assembly of the inner ring 5 and the outer ring 4, both the outer ring 4 and the inner ring 5 are loaded through a vibration plate, and the inner ring 5 is made of silicone material. Under high temperature conditions, it is easy to stick in the vibration plate and difficult to separate, resulting in poor loading conditions and low work efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a hair extension buckle assembly device.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: including an inner ring loading device, an outer ring loading device and an assembly device, the inner ring loading device: loading the inner ring to the assembly device; the outer ring loading device: loading the outer ring to the assembly device; the assembly device: receiving the outer ring and the inner ring respectively and assembling the inner ring to the outer ring, and then unloading the assembled inner and outer rings; the inner ring loading device includes a raw material receiving roll, a guide tube, a driving wheel group, a cutting piece and a cutting drive mechanism, the assembly device includes an inner ring turntable and a main motor, the main motor The machine drives the inner ring turntable to rotate and the inner ring turntable is provided with an inner ring hole for placing the inner ring, the guide tube is arranged opposite to the inner ring hole, the raw material storage roll is arranged opposite to the guide tube and the silicone tube is provided to the guide tube, the silicone tube passes through the guide tube, the driving wheel group is arranged on both sides of the guide tube and drives the movement of the silicone tube in the guide tube, the cutting piece is arranged between the guide tube and the inner ring turntable, the cutting drive mechanism drives the cutting piece to move, the cutting piece has a cutting state on the inner ring hole and a non-cutting state outside the inner ring hole, and the cutting piece can be a blade.

[0007] By adopting the above technical solution, the silicone tube is led out from the raw material storage roll, guided by the guide tube, clamped by the drive wheel group and transported to the cutting position, and the cutting drive mechanism controls the lateral movement of the cutting piece, and cuts the silicone tube above the inner ring hole of the inner ring turntable to form a single inner ring, which falls into the inner ring hole and rotates with the inner ring turntable; the outer ring loading device synchronously transports the outer ring to the assembly station, and the assembly device presses the inner ring into the outer ring to complete the assembly and then unloads; continuous pipe cutting and forming is used instead of vibration plate loading to completely avoid the high-temperature adhesion problem of the silicone inner ring; the guide tube and the drive wheel group ensure the precise feeding of the silicone tube, and the cutting of the cutting piece is linked with the turntable station to realize automatic material division, which significantly improves the loading stability and assembly efficiency.

[0008] The present invention is further configured as follows: the cutting drive mechanism includes a sliding rail, a sliding block, a tension spring and a pulling disk, the sliding rail is arranged in the direction approaching and away from the inner ring hole, the sliding block is slidably arranged on the sliding rail, and the cutting piece is fixedly arranged on the sliding block, one end of the tension spring is arranged on one side of the sliding rail relatively close to the inner ring hole, and the other end is arranged on the sliding block and drives the sliding block to approach the inner ring hole. A matching wheel is provided on the sliding block, and a main motor drives the pulling disk to rotate, and a notch is provided on the pulling disk, and an arc transition section is provided between the notch and the outer periphery of the pulling disk. The pulling disk has a pulling state, a maintaining state and a releasing state. In the pulling state, the arc transition section is against the matching wheel, and the sliding block moves in the direction away from the inner ring hole; in the maintaining state, the outer periphery of the pulling disk cooperates with the matching wheel, and the sliding block is in a position away from the inner ring hole; in the releasing state, the notch is opposite to the matching wheel, and the sliding block moves toward the direction of the inner ring hole under the action of the tension spring.

[0009] By adopting the above technical solution, the main motor drives the pulling disk to rotate. When the arc-shaped transition section contacts the mating wheel, it pushes the sliding block to overcome the tension of the tension spring and move outward along the sliding track; when the outer peripheral surface fits the mating wheel, the sliding block maintains the outward movement state; when the gap turns to the mating wheel, the tension spring instantly rebounds and drives the cutting piece to cut into the inner ring hole at high speed to complete the cutting; through mechanical linkage, the cutting piece can achieve the "fast forward-hover-fast cut" action, and the cutting timing is strictly synchronized with the turntable station; the tension spring energy storage release provides instantaneous cutting force to ensure a smooth incision on the silicone tube; the purely mechanical structure has high reliability and low maintenance cost.

[0013] By adopting the above technical solution, the vertical moving rod is driven by the main motor to descend, driving the insertion rod on the horizontal seat to press down: due to the step-by-step contraction of the inner ring hole, the insertion rod at the receiving station pushes the cut inner ring into the inner ring hole and is located at the highest step; the insertion rod at the middle station presses the inner ring a second time, pressing the inner ring down one step into the inner ring hole; and the insertion rod at the unloading station presses the inner ring into the outer ring of the outer ring turntable below, completing the assembly and unloading; the inner ring hole and the receiving station, the middle station and The synergistic effect of the corresponding insertion rods at the unloading station decomposes the inner ring assembly into three levels of progressive compression: the insertion rod at the receiving station first positions the inner ring at the maximum aperture step to eliminate the initial deformation, and the insertion rod at the middle station presses down a second time to pre-shrink the inner ring to a smaller aperture step to release the elastic stress. Finally, the insertion rod at the unloading station accurately presses the pre-compressed inner ring into the outer ring.
