Description

Technical Field

[0001] This invention relates to an assembly device, specifically a hair clip assembly device. Background Technology

[0002] Hair extensions are a well-known and popular product used to lengthen or add volume to an individual's hair, while blending in or integrating with the wearer's existing hair. Hair extensions allow wearers to adjust the appearance of their hair to achieve a desired look by typically adding multiple strands of extensions with one or more selected lengths and colors.

[0003] like Figure 5 As shown, this is a popular type of nano hair extension clip, which includes an outer ring 4 and an inner ring 5 set inside the outer ring 4. The inner ring 5 is usually made of silicone, which has a certain degree of elasticity. After the inner ring 5 is inserted into the outer ring 4, it is secured to the outer ring by its own elasticity. When extending hair, a hook is used to pass the hair through the inner ring 5, which then clamps and secures the hair.

[0004] Currently, although there is automated assembly equipment for assembling the inner ring 5 and the outer ring 4, both the outer ring 4 and the inner ring 5 are fed by a vibratory feeder. However, the inner ring 5 is made of silicone, which tends to stick together in the vibratory feeder under high temperature conditions and is not easy to separate, resulting in poor feeding and low work efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a hair clip assembly device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes an inner ring feeding device, an outer ring feeding device, and an assembly device. The inner ring feeding device feeds the inner ring to the assembly device; the outer ring feeding device feeds the outer ring to the assembly device; the assembly device receives the outer ring and the inner ring respectively, assembles the inner ring onto the outer ring, and then unloads the assembled inner and outer rings. The inner ring feeding device includes a raw material receiving roll, a guide tube, a drive wheel assembly, a cutting component, and a cutting drive mechanism. The assembly device includes an inner ring turntable and a 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 receiving roll is arranged opposite to the guide tube and provides the silicone tube to the guide tube. The silicone tube passes through the guide tube. The drive wheel set is arranged on both sides of the guide tube and drives the silicone tube to move in the guide tube. The cutting part is arranged between the guide tube and the inner ring turntable. The cutting drive mechanism drives the cutting part to move. The cutting part has a cutting state located on the inner ring hole and a non-cutting state located outside the inner ring hole. The cutting part can be a blade.

[0007] By adopting the above technical solution, the silicone tube is drawn out from the raw material receiving roll, guided by the guide tube, clamped by the drive wheel set and transported to the cutting position. The cutting drive mechanism controls the lateral movement of the cutting part, and cuts the silicone tube above the inner ring hole of the inner ring turntable to form a single inner ring. The inner ring falls into the inner ring hole and rotates with the inner ring turntable. The outer ring feeding device simultaneously transports the outer ring to the assembly station. The assembly device presses the inner ring into the outer ring to complete the assembly and then unloads the material. The use of continuous tube cutting and forming to replace vibratory feeder feeding completely avoids the problem of high-temperature adhesion of silicone inner rings. The guide tube and drive wheel set ensure accurate feeding of the silicone tube. The cutting of the cutting part and the turntable station are linked to realize automated material distribution, which significantly improves the stability of feeding and assembly efficiency.

[0008] The invention is further configured such that: the cutting drive mechanism includes a sliding track, a sliding block, a tension spring, and a pulling disc; the sliding track is arranged along the direction approaching and away from the inner ring hole; the sliding block is slidably disposed on the sliding track; the cutting piece is fixedly disposed on the sliding block; one end of the tension spring is disposed on the side of the sliding track relatively close to the inner ring hole, and the other end is disposed on the sliding block and drives the sliding block to approach the inner ring hole; a mating wheel is disposed on the sliding block; the main motor drives the pulling disc to rotate; a notch is disposed on the pulling disc; an arc-shaped transition section is disposed between the notch and the outer periphery of the pulling disc; the pulling disc has a pulling state, a holding state, and a releasing state; in the pulling state, the arc-shaped transition section abuts against the mating wheel, and the sliding block moves along the direction away from the inner ring hole; in the holding state, the outer periphery of the pulling disc engages with the mating 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 mating wheel, and the sliding block moves towards 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 pull plate 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 circumference is in contact with the mating wheel, the sliding block is kept in an outward state. When the notch turns to the mating wheel, the tension spring rebounds instantly, driving the cutting part to cut into the inner ring hole at high speed to complete the cutting. The mechanical linkage realizes the "fast advance-hover-fast cut" action of the cutting part, and the cutting timing is strictly synchronized with the turntable station. The energy storage and release of the tension spring provides instantaneous cutting force to ensure that the silicone tube cut is flat. The purely mechanical structure has high reliability and low maintenance cost.

[0010] The present invention is further configured such that: the outer ring feeding device includes a vibratory feeder and a feeding track, and the assembly device also includes an outer ring turntable, the outer ring turntable is provided with an outer ring hole, the feeding track is connected to the vibratory feeder, and the outer ring hole has a receiving position opposite to the feeding track and an assembly position located below the inner ring hole.

[0011] By adopting the above technical solution, the vibratory feeder orients and sorts the outer rings, and then transports them to the receiving station of the outer ring turntable via the feeding track; the rotation of the outer ring turntable moves the outer rings to the assembly station, aligning them with the unloading station of the inner ring turntable above; the metal outer rings are suitable for vibratory feeder feeding and there is no risk of adhesion, forming a complementary solution with traditional inner ring feeding; the double turntable structure enables precise alignment of the inner and outer ring stations, laying the foundation for the pressing process.

[0012] The invention is further configured such that: the assembly device includes a vertical moving rod, a horizontal seat, and insert rods; the main motor drives the vertical moving rod to move vertically; the horizontal seat is located at the top of the vertical moving rod; there are multiple inner ring holes; the inner ring turntable is provided with a receiving station, an intermediate station, and an unloading station; when the inner ring hole is located at the receiving station, the inner ring hole is opposite to the guide tube; when the inner ring hole is located at the unloading station, the inner ring hole is opposite to the outer ring hole; the intermediate station is located between the receiving station and the unloading station; the inner ring hole has a stepped contraction; multiple insert rods are respectively opposite to the receiving station, the intermediate station, and the unloading station, and the ends of the multiple insert rods are adapted to the shape of the stepped contraction section of the inner ring hole in the order of receiving station, intermediate station, and unloading station.

[0013] By adopting the above technical solution, the vertical moving rod is driven down by the main motor, causing the insert rod on the horizontal seat to press down: due to the stepped contraction of the inner ring hole, the insert rod located at the receiving station pushes the cut inner ring into the inner ring hole and is located at the highest step; the insert rod located at the middle station presses the inner ring a second time, pressing the inner ring into the inner ring hole another step; and the insert rod located at the unloading station presses the inner ring into the outer ring of the lower outer ring turntable, completing the assembly and unloading; through the stepped contraction of the inner ring hole and the receiving station, the middle station and The coordinated action of the insertion rods at the unloading station decomposes the inner ring assembly into three stages of progressive compression: the insertion rod at the receiving station first positions the inner ring at the maximum aperture step to eliminate initial deformation; the insertion rod at the intermediate station presses down a second time to pre-shrink the inner ring to a smaller aperture step to release elastic stress; finally, the insertion rod at the unloading station precisely presses the pre-compressed inner ring into the outer ring. This design significantly reduces the risk of tearing caused by one-time pressing of the silicone inner ring, while the physical limitation of the stepped hole ensures a uniform compression state of the inner ring, resulting in high assembly accuracy.

[0014] The present invention is further configured such that the assembly device includes a first rotating wheel, a second rotating wheel, a coaxial rotating wheel, an outer ring rotating wheel, an inner ring rotating wheel, a linkage wheel, a first synchronous belt, a second synchronous belt, a rocker arm, and a linkage rod. The main motor drives the first rotating wheel to rotate. The first rotating wheel and the second rotating wheel are linked by the first synchronous belt. The coaxial rotating wheel and the second rotating wheel are coaxially arranged. The coaxial rotating wheel, the outer ring rotating wheel, and the inner ring rotating wheel are linked by the second synchronous belt. The outer ring rotating wheel drives the outer ring turntable to rotate, and the inner ring rotating wheel drives the inner ring turntable to rotate. The linkage wheel is coaxially arranged with the coaxial rotating wheel. One end of the rocker arm is hinged to the linkage wheel and is not located at the axis. The other end is hinged to the vertical moving rod and constitutes the vertical movement of the vertical moving rod. The linkage rod is coaxially arranged with the inner ring rotating wheel and constitutes the rotation of the pull plate. The outer ring rotating wheel can drive the outer ring turntable through a bevel gear set. The inner ring rotating wheel and the pull plate are similarly driven. This is a mature technology and will not be elaborated further.

[0015] By adopting the above technical solution, the main motor drives the second rotating wheel through the first synchronous belt, and synchronously drives the outer ring rotating wheel and the inner ring rotating wheel through the coaxial rotating wheel and the second synchronous belt, and controls the outer ring turntable and the inner ring turntable respectively; the linkage wheel converts the rotational motion into the linear lifting and lowering of the vertical moving rod through the rocker arm; the linkage rod transmits the rotational speed of the inner ring rotating wheel to the pull plate to control the cutting action of the cutting part; a single motor drives all moving parts to ensure precise matching of the timing of the inner and outer ring turntables, the lifting and lowering of the insertion rod, and the cutting of the cutting part; the synchronous belt drive reduces the cumulative assembly error and improves the system coordination and energy efficiency.

[0016] The present invention is further configured such that: the assembly device further includes a shaping rod and an unloading rod; the outer ring turntable is provided with an outer ring station for receiving the outer ring and an assembly station for receiving the inner ring and assembling it with the outer ring; the outer ring station is opposite to the feeding track; the assembly station is opposite to the unloading station and located below the unloading station; the outer ring turntable is also provided with a shaping station located between the outer ring station and the assembly station; the outer ring turntable is provided with an unloading station located on the other side of the assembly station opposite to the outer ring station; the shaping rod is provided on the horizontal seat and opposite to the shaping station; the unloading rod is provided on the horizontal seat and opposite to the unloading station.

[0017] By adopting the above technical solution, when the outer ring turntable moves the outer ring from the outer ring station to the shaping station, the cross seat descends to allow the shaping rod to be inserted into the outer ring hole to correct the deformation; after shaping, it is moved to the assembly station to dock with the inner ring; the shaping process eliminates the outer ring deformation caused by the vibratory feeder, and avoids assembly jamming caused by the ellipticity deviation of the outer ring; the shaping rod and the insertion rod share the same drive source, simplifying the structure.

[0018] The present invention is further configured such that: the drive wheel assembly includes a drive wheel, a drive motor and a driven wheel; the guide tube has mating grooves on both sides that are adapted to the drive wheel and the driven wheel respectively; the drive wheel and the driven wheel are respectively disposed on both sides of the guide tube and are opposite to the mating grooves; the drive motor drives the drive wheel to be opposite to it and constitutes the drive of the silicone tube by the drive wheel and the driven wheel.

[0019] By adopting the above technical solution, the active motor drives the active wheel to rotate, which cooperates with the driven wheel to clamp the silicone tube passing through the guide tube groove, thereby realizing the quantitative advancement of the tube; preventing the silicone tube from slipping or being crushed; the guide groove ensures that the cut section of the tube is straight and guarantees the consistency of the inner ring size.

[0020] Beneficial effects: This equipment completely solves the industry problem of high-temperature adhesion of silicone inner rings. Continuous tube cutting replaces vibratory feeder feeding to ensure a stable supply of inner rings; the mechanical linkage cutting mechanism for cutting parts achieves fast-forward, hovering, and fast-cutting actions, ensuring a smooth cut on the silicone tube; the dual-turntable structure achieves precise alignment of the inner and outer rings; the stepped shrinkage inner ring hole, combined with the three-stage insertion rod progressive compression design, decomposes the inner ring assembly into three stages: pre-positioning, elastic stress release, and final assembly, reducing the damage rate of the silicone inner rings; a single main motor drives all equipment, resulting in high synchronization and low manufacturing costs.

[0030] like Figure 1-5As shown, this invention discloses a hair clip assembly device, including an inner ring feeding device 1, an outer ring feeding device 2, and an assembly device 3. The inner ring feeding device 1 feeds the inner ring to the assembly device 3; the outer ring feeding device 2 feeds the outer ring to the assembly device 3; the assembly device 3 receives the outer ring and the inner ring respectively, assembles the inner ring onto the outer ring, and then unloads the assembled inner and outer rings. The inner ring feeding device 1 includes a raw material receiving roll 11, a guide tube 12, a drive wheel assembly 13, a cutting piece 14, and... The cutting drive mechanism 15 and assembly device 3 include an inner ring turntable 31 and a main motor 32. The main motor 32 drives the inner ring turntable 31 to rotate, and the inner ring turntable 31 is provided with an inner ring hole 311 for placing the inner ring. The guide tube 12 is arranged opposite to the inner ring hole 311. The raw material receiving roll 11 is arranged opposite to the guide tube 12 and provides the silicone tube to the guide tube 12. The silicone tube passes through the guide tube 12. The drive wheel set 13 is arranged on both sides of the guide tube 12 and drives the silicone tube to move in the guide tube 12. Cutting piece 14 is positioned between guide tube 12 and inner ring turntable 31. Cutting drive mechanism 15 drives cutting piece 14 to move. Cutting piece 14 has a cutting state located on inner ring hole 311 and a non-cutting state located outside inner ring hole 311. Silicone tube is led out from raw material receiving roll 11, guided by guide tube 12, clamped by drive wheel set 13 and transported to the cutting position. Cutting drive mechanism 15 controls cutting piece 14 to move laterally, cutting the silicone tube above inner ring hole 311 of inner ring turntable 31. A single inner ring is formed, which falls into the inner ring hole 311 and rotates with the inner ring turntable 31; the outer ring feeding device 2 synchronously transports the outer ring to the assembly station 334, and the assembly device 3 presses the inner ring into the outer ring to complete the assembly and then unloads the material; continuous tube cutting and forming is used to replace the vibratory plate 21 for feeding, which completely avoids the problem of high temperature adhesion of silicone inner rings; the guide tube 12 and the drive wheel group 13 ensure accurate feeding of silicone tubes, and the cutting part 14 is linked with the turntable station to realize automated material distribution, which significantly improves the stability of feeding and the assembly efficiency.

[0031] The cutting drive mechanism 15 includes a sliding track 151, a sliding block 152, a tension spring 153, and a pulling plate 154. The sliding track 151 is arranged along the direction of approaching and moving away from the inner ring hole 311. The sliding block 152 is slidably disposed on the sliding track 151. The cutting piece 14 is fixedly disposed on the sliding block 152. One end of the tension spring 153 is disposed on the side of the sliding track 151 that is relatively close to the inner ring hole 311, and the other end is disposed on the sliding block 152 and drives the sliding block 152 to approach the inner ring hole 311. A mating wheel 155 is disposed on the sliding block 152. The main motor 32 drives the pulling plate 154 to rotate. 4 is provided with a notch 156, and an arc-shaped transition section 157 is provided between the notch 156 and the outer periphery of the pull plate 154. The pull plate 154 has a pulling state, a holding state, and a releasing state. In the pulling state, the arc-shaped transition section 157 abuts against the mating wheel 155, and the sliding block 152 moves away from the inner ring hole 311. In the holding state, the outer periphery of the pull plate 154 engages with the mating wheel 155, and the sliding block 152 is in a position away from the inner ring hole 311. In the releasing state, the notch 156 is opposite to the mating wheel 155, and the sliding block 152 moves towards the inner ring hole 311 under the action of the tension spring 153. The main motor 32 drives the pull plate 154 to rotate. When the arc transition section 157 contacts the mating wheel 155, it pushes the sliding block 152 to overcome the tension of the tension spring 153 and move outward along the sliding track 151. When the outer circumferential surface is in contact with the mating wheel 155, the sliding block 152 is kept in the outward state. When the notch 156 turns to the mating wheel 155, the tension spring 153 rebounds instantly, driving the cutting piece 14 to cut into the inner ring hole 311 at high speed to complete the cutting. The cutting piece 14 achieves the "fast advance-hover-fast cut" action through mechanical linkage, and the cutting timing is strictly synchronized with the turntable station. The tension spring 153 stores energy and releases it to provide instantaneous cutting force, ensuring that the silicone tube cut is flat. The pure mechanical structure has high reliability and low maintenance cost.

[0032] The outer ring feeding device 2 includes a vibratory feeder 21 and a feeding track 22. The assembly device 3 also includes an outer ring turntable 33. The outer ring turntable 33 is provided with an outer ring hole 331. The feeding track 22 is connected to the vibratory feeder 21. The outer ring hole 331 has a receiving position opposite to the feeding track 22 and an assembly position located below the inner ring hole 311. After the vibratory feeder 21 orients and sorts the outer rings, they are transported to the receiving position of the outer ring turntable 33 via the feeding track 22. The outer ring turntable 33 rotates to move the outer rings to the assembly position 334, which is aligned with the unloading position 314 of the upper inner ring turntable 31. The metal outer rings are suitable for feeding with the vibratory feeder 21 without the risk of adhesion, forming a complementary solution with the traditional inner ring feeding. The double turntable structure realizes the precise alignment of the inner and outer ring positions, laying the foundation for the pressing process.

[0033] Assembly device 3 also includes a vertical moving rod 34, a horizontal seat 35, and insert rods 36. The main motor 32 drives the vertical moving rod 34 to move vertically. The horizontal seat 35 is located at the top of the vertical moving rod 34. Multiple inner ring holes 311 are present. The inner ring turntable 31 is equipped with a receiving station 312, an intermediate station 313, and an unloading station 314. When the inner ring hole 311 is located at the receiving station 312, it is opposite to the guide tube 12. When the inner ring hole 311 is located at the unloading station 314, it is opposite to the outer ring hole 331. The intermediate station 313 is located between the receiving station 312 and the unloading station 314. The inner ring hole 311 has a stepped contraction. Multiple insert rods 36 are respectively positioned at the receiving station 312, the intermediate station 313, and the guide tube 12. The 13th and unloading stations 314 are opposite to each other and the ends of the multiple insert rods 36 are adapted to the stepped shrinkage section shape of the inner ring hole 311 in the order of receiving station 312, intermediate station 313 and unloading station 314. The vertical moving rod 34 is driven down by the main motor 32, which drives the insert rods 36 on the cross seat 35 to press down: Since the inner ring hole 311 is stepped shrinkage, the insert rod 36 located at the receiving station 312 pushes the cut inner ring into the inner ring hole 311 and is located at the highest step; the insert rod 36 located at the intermediate station 313 presses the inner ring a second time, pressing the inner ring into the inner ring hole 311 by another step; and the insert rod 36 located at the unloading station 314 presses the inner ring into the outer ring of the lower outer ring turntable 33, and unloads after assembly; Through the coordinated action of the stepped shrinking inner ring hole 311 and the corresponding insertion rods 36 at the receiving station 312, intermediate station 313, and unloading station 314, the inner ring assembly is decomposed into three-stage progressive compression: the insertion rod 36 at the receiving station 312 first positions the inner ring at the maximum aperture step to eliminate initial deformation; the insertion rod 36 at the intermediate station 313 presses down a second time to pre-shrink the inner ring to a smaller aperture step to release elastic stress; finally, the insertion rod 36 at the unloading station 314 precisely presses the pre-compressed inner ring into the outer ring. This design significantly reduces the risk of tearing caused by one-time pressing of the silicone inner ring, while the physical limit of the stepped hole ensures a uniform compression state of the inner ring, resulting in high assembly accuracy.

[0034] Assembly device 3 also includes a first rotating wheel 321, a second rotating wheel 322, a coaxial rotating wheel 323, an outer ring rotating wheel 324, an inner ring rotating wheel 325, a linkage wheel 326, a first synchronous belt 327, a second synchronous belt 328, a rocker arm 329, and a linkage rod 320. The main motor 32 drives the first rotating wheel 321 to rotate. The first rotating wheel 321 and the second rotating wheel 322 are linked by the first synchronous belt 327. The coaxial rotating wheel 323 and the second rotating wheel 322 are coaxially arranged. The coaxial rotating wheel 323, the outer ring rotating wheel 324, and the inner ring rotating wheel 325 are linked by the second synchronous belt 328. The outer ring rotating wheel 324 drives the outer ring turntable 33 to rotate, and the inner ring rotating wheel 325 drives the inner ring turntable 31 to rotate. The linkage wheel 326 is coaxially arranged with the coaxial rotating wheel. One end of the rocker arm 329 is hinged to the linkage wheel 326 but not located at the axis. One end is hinged to the vertical moving rod 34, constituting the vertical movement of the vertical moving rod 34. The linkage rod 320 is coaxially arranged with the inner ring rotating wheel 325, constituting the rotation of the pull plate 154. The outer ring rotating wheel 324 can drive the outer ring rotating plate 33 through the bevel gear set. The inner ring rotating wheel 325 and the pull plate 154 are similarly configured, which is a mature technology and will not be elaborated further. The main motor 32 drives the second rotating wheel 322 through the first synchronous belt 327, and synchronously drives the outer ring rotating wheel 324 and the inner ring rotating wheel 325 through the coaxial rotating wheel 323 and the second synchronous belt 328, and controls the outer ring rotating plate 33 and the inner ring rotating plate 31 respectively. The linkage wheel 326 converts the rotational motion into the linear lifting and lowering of the vertical moving rod 34 through the rocker arm 329. The linkage rod 320 transmits the rotational speed of the inner ring rotating wheel 325 to the pull plate 154 to control the action of the cutting piece 14. A single motor drives all moving parts, ensuring precise timing matching of the lifting of the inner and outer ring turntables 33 and the insertion rod 36, and the cutting of the cutting parts 14; synchronous belt drive reduces accumulated assembly errors and improves system coordination and energy efficiency.

[0035] The assembly device 3 further includes a shaping rod 37 and a unloading rod 38. The outer ring turntable 33 is provided with an outer ring station 332 for receiving the outer ring and an assembly station 334 for receiving the inner ring and assembling it with the outer ring. The outer ring station 332 is opposite to the feeding track 22, and the assembly station 334 is opposite to and below the unloading station 314. The outer ring turntable 33 also has a shaping station 333 located between the outer ring station 332 and the assembly station 334. The outer ring turntable 33 also has an unloading station 335 located on the other side of the assembly station 334 opposite to the outer ring station 332. The shaping rod 37 is mounted on the horizontal seat 35 and opposite the shaping station 333, and the unloading rod 38 is mounted on the horizontal seat 35 and opposite the unloading station 335. When the outer ring turntable 33 rotates the outer ring from the outer ring station 332 to the shaping station 333, the cross seat 35 descends to allow the shaping rod 37 to be inserted into the outer ring hole 331 to correct the deformation; after shaping, it is rotated to the assembly station 334 to dock with the inner ring; the shaping process eliminates the outer ring deformation caused by the conveying of the vibrating plate 21 and avoids assembly jamming caused by the ellipticity deviation of the outer ring; the shaping rod 37 and the insertion rod 36 share the same drive source, simplifying the structure.

[0036] The drive wheel assembly 13 includes a drive wheel 131, a drive motor 132, and a driven wheel 133. The guide tube 12 has mating grooves 134 on both sides, each adapted to the drive wheel 131 and the driven wheel 133. The drive wheel 131 and the driven wheel 133 are respectively located on both sides of the guide tube 12 and opposite to the mating grooves 134. The drive motor 132 drives the drive wheel 131 to rotate, thus cooperating with the driven wheel 133 to clamp the silicone tube passing through the mating grooves 134 of the guide tube 12, achieving quantitative feeding of the tube and preventing slippage or crushing of the silicone tube. The mating grooves 134 guide and ensure the straightness of the cut section of the tube, guaranteeing consistent inner ring dimensions.

[0037] Working process: The silicone tube is drawn out from the raw material receiving roll 11, guided by the guide tube 12, and then clamped and conveyed to the cutting position by the drive wheel set 13; the main motor 32 drives the pull plate 154 to rotate, and pushes the sliding block 152 to move outward against the tension of the tension spring 153 through the arc transition section 157. When the notch 156 of the pull plate 154 is aligned with the mating wheel 155, the tension spring 153 rebounds and drives the cutting piece 14 to cut the silicone tube at high speed. The formed inner ring falls into the stepped shrinking inner ring hole 311 of the inner ring turntable 31; the inner ring turntable 31 rotates and moves the inner ring to the receiving station 312, the intermediate station 313 and the unloading station 314 in sequence. At the same time, the main motor 32 drives the vertical moving rod 34 to descend, driving the insertion rod 36 on the horizontal seat 35 to move in three stages: at the receiving station 312, the intermediate station 313 and the unloading station 314. The insert rod 36 of 12 positions the inner ring to the maximum diameter step. The insert rod 36 at the intermediate station 313 presses down a second time to shrink the inner ring to a smaller diameter step to release stress. The insert rod 36 at the unloading station 314 presses the pre-compressed inner ring into the outer ring hole 331 of the lower outer ring turntable 33. The outer ring is sorted by the vibrating plate 21 and then transported to the receiving position of the outer ring turntable 33 via the feeding track 22. After the deformation is corrected by the shaping rod 37 at the shaping station 333, it is transferred to the assembly station 334. After assembly, the unloading rod 38 unloads the assembled inner and outer rings from the outer ring hole 331. The main motor 32 drives the inner and outer ring turntables 33 and the insert rod 36 to lift and lower and the cutting part 14 to cut through the synchronous belt system, and finally completes the unloading of the assembled hair clip.
