Description

Technical Field

[0001] This invention relates to the field of hair transplant equipment technology, and more specifically to automatic hair transplant equipment and its usage method. Background Technology

[0002] Currently, most human body models are made of silicone. In order to make the model more realistic, hair needs to be implanted in the head of the model. The common method is to manually insert each hair into the head one by one after the silicone is molded and before it solidifies and hardens, so as to complete the hair transplantation work of the human body model.

[0003] According to publication number CN209079008U, publication date: July 9, 2019, an automatic hair implantation device for a human model is disclosed, comprising: a shell, a contact panel, implantation needles, fixing rings, cams, and a motor. The lower end of the shell has an arc-shaped contact panel, and multiple fixing rings are located on both sides of the lower end of the shell. A fixing plate is located inside the shell, and multiple implantation needles are located at the lower end of the fixing plate. The implantation needles pass through the contact panel, and springs are fitted onto the implantation needles, with the springs positioned between the fixing plate and the contact panel. A handle is installed on the right end of the shell, and a motor is located inside the handle. The motor's drive end is connected to a rotating shaft, and multiple cams are fitted onto the rotating shaft, with the cams contacting the fixing plate. In the above embodiment of this utility model, the problem of time-consuming and laborious manual hair implantation is solved. The hair is initially fixed by the fixing rings and fixing sponge, and with the cooperation of the motor and cams, the implantation needles automatically implant the hair into the head of the human model. The operation is simple and the implantation efficiency is high.

[0004] In the prior art, including the aforementioned patent, the two ends of the hair are fixed in the fixing ring, and the implantation needle slides vertically to push the middle of the hair into the model head. However, when the implantation needle moves to push the middle of the hair, the two ends of the hair are no longer fixed to the fixing ring 4, so the hair is no longer tightened. At this time, the hair is loosely implanted into the model head, which easily leads to the hair implantation position being curved, resulting in the implanted hair being messy, irregular and easy to fall out.

[0014] Preferably, the bottom surface of the sliding cavity is provided with an annular guide slope, and the guide slope is positioned at a low position towards the inner ring side of the hair transplant needle.

[0015] A method for using an automated hair transplant device, including the automated hair transplant device described above, comprises the following steps:

[0016] S1. First, add a certain amount of lubricating oil to the oil reservoir.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0033] like Figure 1-7 As shown, the automatic hair transplant device and its usage method include a base 1 on which material hooks 11 are arranged in a symmetrical linear array. Hair transplant needles 2 are vertically slidably arranged on the base 1 between the material hooks 11. A tensioning seat 3 is symmetrically and horizontally slidably arranged on the base 1. Hook grooves 31 are linearly arrayed on the tensioning seat 3. In the default state, the tensioning seat 3 aligns several hook grooves 31 with multiple sets of material hooks 11 and hair transplant needles 2. The hair transplant needles 2 are driven to slide out of the outside of the base 1 to drive the tensioning seat 3 to slide horizontally.

[0034] Specifically, such as Figure 1As shown, a number of placement hooks 11 and hair transplant needles 2 are linearly arrayed on the base 1. The ends of the hair transplant needles 2 are provided with pressing grooves 21. The hair transplant needles 2 are positioned between the placement hooks 11. A tensioning seat 3 is horizontally slidably positioned between the hair transplant needles 2 and the placement hooks 11. When a hair transplant is needed, the hair is first passed through the placement hooks 11, the hooking grooves 31 of the tensioning seat 3, and the pressing grooves 21 of the hair transplant needles 2 simultaneously, so that both ends of the hair are roughly fixed to the placement hooks 11, and the middle of the hair is aligned with the pressing grooves of the hair transplant needles 2. With the 21 aligned, the model head can be placed under the base 1. Then, the hair implantation needle 2 slides vertically downward to extend outward from the base 1. The hair implantation needle 2 pushes against the middle of the hair and inserts into the model head. The tensioning seat 3 is driven by the hair implantation needle 2 to move horizontally, thereby enabling the hook groove 31 to pull the two ends of the hair to move horizontally. This tightens the two ends of the hair that have not been inserted into the model head, so that the hair is implanted into the model head in a taut state, improving the regularity and stability of hair implantation.

[0035] The tensioning seat 3 is provided with a moving part 32, and the base 1 is provided with a sliding groove 17. The moving part 32 is slidably disposed in the sliding groove 17 to improve the horizontal sliding stability of the tensioning seat 3.

[0036] In the above technical solution, the hair transplant needle 2 is used to push the middle of the hair into the head of the model, while the tensioning seat 3 is driven by the hair transplant needle 2 to move horizontally, thereby enabling the hook groove 31 to pull the two ends of the hair to move horizontally, thereby tightening the two ends of the hair that have not been inserted into the head of the model, so that the hair is implanted into the head of the model in a taut state, improving the regularity and fixation stability of the hair implantation.

[0037] As another embodiment of the present invention, a drive rod 41 and a drive motor 42 for driving the drive rod 41 to rotate are provided in the base 1. A cam part 411 is provided on the drive rod 41, and a sliding part 22 is provided on the hair transplant needle 2. The sliding part 22 is vertically slidably disposed in a sliding cavity 12 opened in the base 1. The drive rod 41 is driven to rotate, causing the cam part 411 to rotate and push the sliding part 22 to slide, so that the hair transplant needle 2 slides vertically back and forth.

[0038] Specifically, such as Figure 2 As shown, the drive rod 41 is rotatably mounted within the rotating cavity 16 of the base 1, and the drive rod 41 is fixedly connected to the output end of the drive motor 42, as shown. Figure 3As shown, a cam portion 411 is provided on the drive rod 41, and the sliding portion 22 of the hair transplant needle 2 is slidably disposed in the sliding cavity 12 of the base 1. When the drive motor 42 drives the drive rod 41 to rotate the cam portion 411 in a circumferential direction, the cam portion 411 will squeeze the sliding portion 22 to slide, so that the hair transplant needle 2 can slide vertically, thereby enabling the hair transplant needle 2 to push the hair to move and perform the hair transplant operation. The drive rod 41 and the drive motor 42 are used to drive the hair transplant needle 2 to slide vertically, thereby improving the running stability of the hair transplant needle 2 and improving the stability of the hair transplant operation.

[0039] Secondly, a first elastic element 71 is symmetrically arranged in the sliding cavity 12 for pushing the sliding part 22 to slide vertically upward and reset. The first elastic element 71 can be a spring. The drive motor 42 is connected to an external power supply. The drive motor 42, the external power supply and their electrical connection are common technical knowledge known to those skilled in the art and will not be described in detail here.

[0040] As another embodiment of the present invention, a transmission rack 6 is rotatably provided inside the base 1. The transmission rack 6 is coupled with the straight tooth surface provided on the tensioning seat 3. A rack portion 231 is symmetrically provided on the hair transplant needle 2. The hair transplant needle 2 is driven to drive the rack portion 231 to slide vertically so as to drive the tensioning seat 3 to slide horizontally through the transmission rack 6.

[0041] Specifically, such as Figure 6 As shown, the rack portion 231 on the hair transplant needle 2 is coupled to the transmission rack 6, and the transmission rack 6 is also coupled to the straight tooth surface on the tensioning seat 3. When the drive rod 41 is driven to rotate to drive the hair transplant needle 2 to slide vertically, the rack portion 231 slides vertically to drive the tensioning seat 3 to slide horizontally through the transmission rack 6, thereby achieving the tightening of both ends of the hair in the hair transplant operation, improving the regularity and stability of hair implantation. The transmission rack 6 is used to realize the transmission of the hair transplant needle 2 to the tensioning seat 3, so that no additional drive source is needed, improving the driving stability and operational stability of the hair transplant needle 2 to the tensioning seat 3.

[0042] As another embodiment of the present invention, a through groove 18 is symmetrically provided on the base 1, and the rack portion 231 is vertically slidably disposed in the through groove 18. The hair transplant needle 2 is driven to slide vertically downward so that the rack portion 231 slides and extends out of the base 1 through the through groove 18.

[0043] Specifically, such as Figure 4As shown, a through groove 18 is provided on the base 1, and the rack part 231 is slidably disposed in the through groove 18. When the drive rod 41 is driven to rotate to drive the hair transplant needle 2 to slide vertically, the rack part 231 slides vertically to drive the tensioning seat 3 to slide horizontally through the transmission rack 6. At this time, the through groove 18 is used to improve the sliding stability of the rack part 231. When the hair transplant needle 2 is driven to move vertically downward to insert the hair into the model head for hair transplantation, the end of the rack part 231 extends out of the base 1 through the through groove 18 to squeeze the two sides of the hair transplant position of the model head, thereby reducing the squeezing force on the periphery of the hair transplant position corresponding to the hair transplant needle 2, which facilitates the increase of the fixing depth of the hair piercing into the model head, thereby further improving the stability of the hair implanted on the model head.

[0044] As another embodiment of the present invention, an oil storage cavity 13 and an inflow hole 132 are symmetrically provided on the base 1. The inflow hole 132 is connected to the sliding cavity 12. A guide channel 222 is symmetrically provided on the sliding part 22. The first end of the guide channel 222 is connected to both ends of the sliding part 22, and the second end of the guide channel 222 is connected to the needle part facing the hair transplant needle 2. A flip seat 8 is symmetrically rotatably provided inside the base 1. A blocking part 811 for blocking the inflow hole 132 is provided on the extension 81 of the flip seat 8. The hair transplant needle 2 is driven to slide vertically to a high position so that the sliding part 22 pushes against the flip seat 8 and flips over, no longer blocking the inflow hole 132. The first end of the guide channel 222 is aligned with the inflow hole 132.

[0045] Specifically, such as Figure 2 As shown, an oil storage cavity 13 and an inflow hole 132 are symmetrically provided on the base 1. The inflow hole 132 is connected to the sliding cavity 12. An oil injection port 131 connected to the oil storage cavity 13 is also provided on the base 1. Lubricating oil can be injected into and stored in the oil storage cavity 13 through the oil injection port 131. The sliding part 22 of the hair implantation needle 2 is also provided with an abutment groove 221. The flipping seat 8 is rotatably disposed in the base 1. The flipping seat 8 is provided with a mounting part 82. A second elastic member 72 is also provided in the base 1, one end of which is connected to the mounting part 82. The second elastic member 72 drives the flipping seat 8 to be in the default state. The sealing part 811 of the flip seat 8 blocks the inflow hole 132. When the hair transplant needle 2 is in the high position of the sliding stroke, the abutment groove 221 of the sliding part 22 abuts against the extension part 81 of the flip seat 8 so that the sealing part 811 of the flip seat 8 moves away from the inflow hole 132. At this time, the inflow hole 132 is not blocked, and the lubricating oil in the oil storage cavity 13 can flow into the first end of the guide channel 222 through the inflow hole 132. The lubricating oil flows along the guide channel 222 and adheres to the periphery of the hair transplant needle 2, thereby achieving lubrication of the vertical sliding of the hair transplant needle 2 and improving the sliding stability of the hair transplant needle 2.

[0046] When the hair transplant needle 2 slides vertically to a low position to perform the hair transplant operation, the second elastic element 72 pulls the flip seat 8 to rotate to the default state, and the sealing part 811 seals the inflow hole 132 to prevent the lubricating oil from continuously entering the sliding cavity 12 and causing the oil to drip down along the hair transplant needle 2 onto the model head, thus improving the cleanliness of the hair transplant operation.

[0047] The second elastic element 72 can be a spring.

[0048] As another embodiment of the present invention, a movable cavity 14 is provided in the base 1, and a movable part 23 is coaxially provided on the hair transplant needle 2, and the movable part 23 is axially movable in the movable cavity 14.

[0049] Specifically, such as Figure 3 As shown, a movable cavity 14 is provided inside the base 1, and a movable part 23 is coaxially provided on the hair transplant needle 2. The movable part 23 is axially movable in the movable cavity 14. The axial sliding of the movable part 23 of the hair transplant needle 2 in the movable cavity 14 improves the vertical sliding stability of the hair transplant needle 2 and reduces the radial vibration of the hair transplant needle 2 when performing hair transplantation in a vertical sliding manner. This further improves the regularity of hair implantation on the model head. Secondly, the presence of the movable cavity 14 can also be used to store excess lubricating oil, further preventing the lubricating oil from dripping from the peripheral surface of the hair transplant needle 2 onto the model head and causing dirt.

[0050] As another embodiment of the present invention, a recovery chamber 15, a recovery channel 151 and a reset channel 152 are symmetrically provided in the base 1. The recovery chamber 15 is connected to the movable chamber 14 through the recovery channel 151 and is connected to the oil storage chamber 13 through the reset channel 152. The recovery chamber 15 is located on the vertically lower side of the movable chamber 14. A pumping pump 91 is provided in the reset channel 152.

[0051] Specifically, such as Figure 2 As shown, a recovery chamber 15, a recovery channel 151, and a reset channel 152 are symmetrically arranged in the base 1. The recovery chamber 15 is connected to the movable chamber 14 through the recovery channel 151, and the recovery chamber 15 is connected to the oil storage chamber 13 through the reset channel 152. When the lubricating oil in the oil storage chamber 13 flows into the sliding chamber 12 through the inlet hole 132 and the guide channel 222, the excess lubricating oil will gradually enter the movable chamber 14 as the hair implantation needle 2 slides vertically. At this time, due to the presence of the recovery channel 151, the excess lubricating oil will flow into the recovery chamber 15, and the excess oil in the recovery chamber 15 will be absorbed into the oil storage chamber 13 by the extraction pump 91 and the reset channel 152 to complete the recovery. This further avoids the problem of excess oil dripping along the hair implantation needle 2 and causing dirt to grow on the head of the model. Secondly, the excess lubricating oil is recovered to reduce the consumption rate of the lubricating oil and ensure the long-term stable operation of the hair implantation needle 2.

[0052] As another embodiment of the present invention, a rotating roller 5 is symmetrically rotatably arranged on the base 1. The rotation axis of the rotating roller 5 is arranged vertically. A first helical tooth 412 is symmetrically arranged on the drive rod 41. The first helical tooth 412 is coupled to a second helical tooth 51 arranged on the rotating roller 5.

[0053] Specifically, such as Figure 5 As shown, a rotating roller 5 is symmetrically rotatably mounted on the base 1. The rotation axis of the rotating roller 5 is arranged vertically. A first helical tooth 412 is symmetrically mounted on the drive rod 41. The first helical tooth 412 is coupled with a second helical tooth 51 mounted on the rotating roller 5. When the drive motor 42 drives the drive rod 41 to rotate axially, the drive rod 41 uses the first helical tooth 412 and the second helical tooth 51 to drive the rotating roller 5 to rotate around the vertical axis. This utilizes the angular momentum generated by the rotating roller 5 to reduce the vibration on the base 1, thereby offsetting and mitigating the vibration caused by the circumferential rotation of the cam part 411 on the drive rod 41. This further reduces the vertical sliding error of the hair implantation needle 2 on the base 1 and improves the stability of the hair implantation operation.

[0054] As another embodiment of the present invention, the bottom surface of the sliding cavity 12 is provided with an annular guide slope 121, and the guide slope 121 is positioned at a low position towards the inner ring side of the hair transplant needle 2.

[0055] Specifically, such as Figure 2 As shown, an annular guide slope 121 is provided on the bottom surface of the sliding cavity 12, and the guide slope 121 is positioned at a low position facing the inner ring side of the hair transplant needle 2. The guide slope 121 is used to guide the lubricating oil in the sliding cavity 12 to the periphery of the hair transplant needle 2, thereby further lubricating the hair transplant needle 2 and improving the vertical sliding stability of the hair transplant needle 2.

[0056] Working principle:

[0057] S1. First, add a certain amount of lubricating oil into the oil storage chamber 13;

[0058] S2. Then, the hair is passed through the material hook 11 and the hook groove 31 in sequence so that the two ends of the hair are fixed on the material hook 11, and the middle of the hair is located vertically below the hair transplant needle 2.

[0059] S3. Place the head of the model with the required value below the base 1 and fix it.

[0060] S4. Then start the drive motor 42 to make the drive rod 41 rotate. The drive rod 41 rotates to push the hair implantation needle 2 to slide vertically downward to push the middle of the hair into the head of the model. Meanwhile, the tensioning seat 3 moves horizontally to pull the two ends of the hair to move horizontally, thereby tightening the two ends of the hair that have not been inserted into the head of the model.

[0061] S5, drive rod 41 continues to rotate so that hair transplant needle 2 slides vertically and lifts away from the model head, and finally the model head is removed to complete the hair transplant.

[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
