Description

Technical Field

[0001] The invention relates to a brush manufacturing device, in particular to a threading and hair transplanting machine; the invention also relates to a threading and hair transplanting method, belonging to the technical field of brush disc hair transplanting. Background Art

[0002] In the prior art, when implanting bristles of a brush, a countersunk hole is first drilled on the bottom plate of the brush body, and then the bristles are implanted into the hole through the implanting nozzle. There are many types of brushes made, mainly including civilian brushes and industrial brushes. With the progress of society, the use of brushes is becoming more and more extensive. Taking the polishing of optical lenses such as mobile phone screens, computer monitors, and microscopes as an example, a disc brush with a diameter of more than 1m is often required. The brush disc is usually made of plastic. Due to its large size, the cost of the brush disc accounts for a relatively large proportion.

[0003] The Chinese invention patent with publication number CN 201595369U discloses a hair implanting machine, including a frame, on which a main motor, a main shaft, a hair nozzle movement mechanism, a wire cutting mechanism, a needle pushing mechanism and a wire feeding mechanism are installed. The main motor is connected to the main shaft through a synchronous belt and a synchronous pulley, and the hair implanting needle of the needle pushing mechanism is inserted into the hole of the hair nozzle. The hair nozzle movement mechanism includes a hair nozzle conjugate cam, a hair nozzle conjugate rocker arm, a hair nozzle connecting rod, a hair nozzle seat and a hair nozzle. The hair nozzle conjugate cam is installed on the main shaft, the upper end of the hair nozzle conjugate rocker arm is engaged with the hair nozzle conjugate cam through a roller, and its lower end is hinged to the upper end of the hair nozzle connecting rod, and the lower end of the hair nozzle connecting rod is hinged to the upper end of the hair nozzle. The hair nozzle is adapted to the hair nozzle seat and can reciprocate up and down in the hair nozzle seat.

[0004] Each movement of the bristle nozzle completes one hair transplantation. The root of each bundle of bristles is wrapped by iron wire and implanted deep into the hole. The iron wire is squeezed and deformed and embedded into the hole wall to hold the bristles tightly.

[0005] For the large disc brushes needed for polishing optical lenses, the brush disc is large in size, with a diameter of 1.3m being common. The brush disc is expensive and difficult to manufacture, with many holes and a long processing time. Once the bristles are slightly worn, they do not meet the requirements of high-end occasions such as optical lens polishing. If the bristles are pulled out and replanted, the brush disc or brush plate can be reused, which will greatly reduce the manufacturing cost of the product, reduce waste, and save social resources.

[0006] The above traditional hair transplanting machines need to cut the iron wire into small pieces, wrap the roots of the bristles and implant them into the holes of the brush plate. The iron wire is embedded in the inner wall of the hole, causing permanent deformation, and it is difficult to remove the bristles cleanly. The iron wire located deep in the small hole and embedded in the hole wall is even more difficult to completely remove, so that the hole is clean again, which will cause the expensive brush plate to be unable to be reused.

[0007] In addition, many polishing occasions require spraying or working underwater to quickly wash away the dust generated by polishing. Since iron wire is prone to rust, if rusty water flows out during polishing, it is very fatal to high-end products such as optical lenses. Moreover, after the iron wire is rusted, the bristles are easy to fall off.

[0008] In order to reduce production costs, many companies organize workers to remove the bristles of discarded brush plates, restore the countersunk holes of the brush plates, drill small holes for threading at the bottom of the countersunk holes of the brush plates, and use manual threading to fix the bristles. Although the brush plates are recycled, the production efficiency is low, the labor intensity is high, and the labor cost is high. After the manual wire pulling, there is a process of letting go and relaxing, which affects the quality of the bristles; and the iron wire is easy to be not cleaned up, which poses a threat to the production of optical lenses.

[0018] Another object of the present invention is to overcome the problems existing in the prior art and provide a threading and hair transplanting method, which can use a single nylon thread or other high-strength thread to automatically and continuously fix the bristles in each hair transplanting hole. While the hair transplanting quality is high, it is easy to pull out the worn bristles completely, restore the holes to clean and re-transplant the hair.

[0019] In order to solve the above technical problems, the present invention provides a method for threading and hair transplanting using the threading and hair transplanting machine described in any one of claims 1 to 8, which comprises the following steps in sequence:

[0020] S1. Manually tie the end of the nylon thread to a hole of the brush plate, and the nylon thread passes under the hole to be planted;

[0021] S2, the workbench moves the brush plate so that the holes to be planted on the brush plate are coaxial with the tubular hair nozzle and the hook;

[0022] S3, the tubular hair nozzle and the hook needle move downward at the same time, and the plucking plate is pushed away during the downward movement of the tubular hair nozzle, and the plucking plate passively rotates downward to perform the plucking action;

[0023] S4, the lower end of the tubular hair nozzle stops when it is close to the hole to be planted on the brush plate;

[0024] S5, the hook continues to move downward, passing through the lower end of the tubular hair nozzle and the hole to be planted, so that the barb on the hook reaches below the nylon line;

[0025] S6, the tubular hair nozzle remains stationary, the hook returns upward, the barb hooks the nylon line and hooks it out of the eyelet to be planted and the tubular hair nozzle, forming a double-stranded line with an opening downward above the hair nozzle platform; during the hooking process, the wire feeder releases the nylon line;

[0026] S7, the opening block rotates forward, so that the tip of the opening cone head is inserted forward between the double strands under the crochet hook, so that they are separated from each other to form an opening; as the opening cone head continues to be inserted, the loop of the opening expands and detaches from the hook of the crochet hook;

[0027] S8, the manipulator inserts a bunch of bristles into the coil and releases it into the bristle placement groove of the bristle nozzle platform, and then the manipulator withdraws;

[0028] S9, the opening block rotates backward, and the opening conical head exits the coil backward;

[0029] S10, the wire feeding machine gathers the nylon wire so that the coil covers the bristles, and continues to gather so that the bristles are folded from the middle to form a U shape, and are pulled into the feeding hole of the bristle nozzle platform and the central hole of the tubular bristle nozzle by the nylon wire; the nylon wire is continued to be gathered, and the roots of the bristles are pulled into the large hole step of the bristle planting hole of the brush plate and fixed;

[0030] S11, the hair mouth platform and the hook return upward and reset, and the hair plucking plate is reset by the torsion spring;

[0031] S12, the workbench moves the next hole to be transplanted with hair on the brush plate to the transplanting station, and repeats S3 to S11, and the cycle continues until the transplanting of hair on all holes is completed.

[0032] As a preferred embodiment of the present invention, the specific actions of the wire feeding machine in step S10 to gather the nylon wire are as follows:

[0033] The wire-reeling servo motor drives the swing arm to rotate upward, and the swing arm cam drives the lower pressure block bracket and the lower pressure block to rise through the lower pressure block roller. The lower pressure block lifts the upper pressure block, and the weight of the upper pressure block presses the nylon wire at the outlet of the wire spindle;

[0034] The wire-retrieving servo motor drives the swing arm to continue to rotate upward, and the distance between the swing arm guide wheel and the floating block guide wheel is enlarged, so that the nylon wire hooked by the hook is pulled back and stored;

[0035] When the root of the bristle reaches the large hole step of the hair planting eyelet, the wire-reeling servo motor drives the swing arm to continue to rotate upward, and the nylon wire drives the floating block of the gravity buffer mechanism to rise, and the weight of the floating block tightens the nylon wire.

[0036] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. The traditional iron wire wrapped bristle roots can be replaced with nylon wire or other high-strength wire to continuously fix the bristles in each hole in an Ω shape. When operating underwater or in water, it will not rust and has a long service life.

[0037] 2. Nylon thread or other high-strength thread can be sent to the bottom of the brush plate hole of the hair planting station, and the position is very precise; during the advancement of the nylon thread, the tension and state are stable and the tension is adjustable to avoid vibration or relaxation, ensuring that twisting is avoided;

[0038] 3. When the hook goes down, it can avoid directly piercing the nylon line. When the hook goes up, the barb on its side wall can reliably hook the nylon line and pull it out from the eye of the brush plate. The open conical head separates the two strands of the nylon line to form a coil, which is convenient for the bristles to enter the nylon line coil, and then the line is collected for fixing.

[0039] 4. The upstream nylon line can be fixed by the wire-reeling servo motor, and the hooked nylon line can be accurately gathered until the nylon line pulls the bristles into the holes of the brush plate and is fixed;

[0040] 5. It completely breaks through the traditional hair transplanting method, eliminating the complex processes required by traditional hair transplanting, such as wire feeding, wire cutting, wire bending, wire wrapping hair roots, and needle transplanting, and provides a solution for automated mechanical threading and hair transplanting;

[0041] 6. Provide a way to recycle old brush discs, brush bodies or brush plates. After the bristles are worn, cut and pull out the nylon thread to easily pull out the bristles. During the process of planting the bristles and after the old bristles are pulled out, the holes of the brush disc or brush plate are not damaged, so that the brush disc or brush body or brush plate can be reused almost unlimited times, reducing the generation of solid waste and greatly reducing production costs.

[0055] In the following description of the present invention, the directions or positional relationships indicated by terms such as "up", "down", "front", "back", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device must have a specific direction.

[0056] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0058] like Figure 1 As shown, the threading and hair transplanting machine of the present invention comprises a base 8, a gantry 9 is installed on the rear side of the base 8, a hair transplanting machine head is installed on the middle front side of the gantry 9, and a brush plate 10 is located below the hair transplanting machine head, and the position of the brush plate 10 is controlled by a workbench. A wire feeder is provided below the brush plate 10, and a wire feeder frame 11 of the wire feeder is fixed to the middle of the front side of the base 8. Each hair transplanting hole of the brush plate 10 is a 6mm countersunk hole, and there is a small hole of about 2mm at the bottom center of the countersunk hole, and the small hole passes through the brush plate 10 for the nylon line to enter and exit.

[0059] like Figures 2 to 5 As shown, the hair transplanting machine head includes a machine head bracket 1, a machine head motor 7, a hair transplanting drive mechanism, a hair plucking mechanism, a hook drive mechanism and an opening drive mechanism. The machine head motor 7 is mounted on the machine head bracket 1. The machine head main shaft 2 is also mounted on the machine head bracket 1. A large pulley 2a is mounted on one end of the machine head main shaft 2, and a hand wheel 2b is mounted on the other end. The small pulley at the rotor shaft end of the machine head motor 7 is connected to the large pulley 2a through a V-shaped belt 7a.

[0060] The hair transplanting driving mechanism includes a hair transplanting cam 3a, a hair transplanting rocker arm 3b, a hair transplanting pull rod 3c, a hair transplanting slide 3d, a hair nozzle platform 3e and a tubular hair nozzle 3f. The hair transplanting cam 3a is installed on the main shaft of the machine head and is a conjugate cam. The hair transplanting rocker arm 3b is a conjugate rocker arm, which is circumferentially meshed with the hair transplanting cam 3a. The root of the hair transplanting rocker arm 3b is hinged on the machine head bracket. The upper end of the hair transplanting pull rod 3c is hinged to the front end of the hair transplanting rocker arm 3b. The lower end of the hair transplanting pull rod 3c is hinged to the hair transplanting slide 3d. The hair transplanting slide 3d is supported on the hair transplanting guide rail 1a extending vertically through a slider. The hair transplanting guide rail 1a is fixed on the machine head bracket 1.

[0061] The bristle nozzle platform 3e is in a horizontal state and is connected to the lower part of the bristle planting slide 3d as a whole. An arc-shaped concave bristle releasing groove 3e1 is provided on the top of the bristle nozzle platform 3e. A vertically penetrating bristle delivery channel is provided at the rear end of the bristle nozzle groove 3e1. A tubular bristle nozzle 3f extending downward is connected to the lower part of the rear end of the bristle nozzle platform 3e. The central channel of the tubular bristle nozzle 3f is coaxial with the bristle delivery channel of the bristle nozzle platform 3e.

[0062] After the head motor 7 is started, the large pulley 2a is driven to rotate through the V-belt 7a, and the large pulley 2a drives the head main shaft 2 to rotate. The head main shaft 2 drives the hair transplanting cam 3a to rotate, and the hair transplanting cam 3a drives the hair transplanting rocker arm 3b to swing back and forth. The hair transplanting rocker arm 3b pulls the hair transplanting slide 3d along the hair transplanting guide rail 1a through the hair transplanting pull rod 3c, and the hair transplanting slide 3d rises or falls synchronously with the hair nozzle platform 3e and the tubular hair nozzle 3f connected to it.

[0063] When the lower end of the tubular bristle nozzle 3f reaches 1mm close to the hair planting hole of the brush plate, it stops. At this time, the robot places a bunch of bristles in the hair placing groove 3e1 of the bristle nozzle platform. The distance between the front end of the hair placing groove 3e1 and the hair feeding hole is greater than half the length of the placed bristles, so that the center of gravity of the bristles is stable and can lie flat in the hair placing groove 3e1 waiting for hair planting.

[0064] Since the implanted bristles are in a fluffy state, the hair crowns are easy to cover the holes next to them where the hair has not been implanted, causing interference. The implanted bristles need to be pushed aside by a hair-plucking mechanism.

[0065] The plucking mechanism includes a plucking seat 6a and a plucking plate 6c. The plucking seat 6a is fixed on the head bracket. The plucking plate 6c is hinged on the plucking seat 6a through a plucking hinge shaft. The free end of the plucking plate 6c extends to the bottom of the tubular bristle nozzle. The plucking hinge shaft is equipped with a torsion spring 6b. When the lower end of the tubular bristle nozzle abuts against the plucking plate 6c and continues to move downward, the plucking plate 6c rotates downward and plucking the bristles below until the lower end of the tubular bristle nozzle approaches or abuts against the hole to be planted on the brush plate and is coaxial; when the tubular bristle nozzle rises, the tension of the torsion spring 6b causes the plucking plate 6c to return to a horizontal state.

[0066] The hook hook driving mechanism includes a hook thread cam 4a, a hook thread rocker arm 4b, a transmission connecting rod mechanism, a hook hook seat 4f and a hook hook 4g. The hook thread cam 4a is installed on the head main shaft 2, and includes a hook thread main cam and a hook thread auxiliary cam which are parallel to each other. The hook thread main cam and the hook thread auxiliary cam are connected by a clamp. The middle of the hook thread rocker arm 4b is the root and is hinged on the head bracket 1. One end of the hook thread rocker arm 4b is engaged with the hook thread main cam through a roller, and the other end is engaged with the hook thread auxiliary cam through a roller.

[0067] The front end of the hook thread rocker arm 4b is hinged to the upper end of the hook thread pull rod 4c, the lower end of the hook thread pull rod 4c is hinged to the rear end of the hook thread middle lever 4d, the middle part of the hook thread middle lever 4d is hinged to the machine head bracket 1, the front end of the hook thread middle lever 4d is hinged to the upper end of the hook thread lower pull rod 4e, and the lower end of the hook thread lower pull rod 4e is hinged to the hook needle seat 4f. The hook needle seat 4f is supported on the hook thread guide rail 1b through a slider, and a hook needle 4g ​​is fixed to one side of the hook needle seat 4f, the needle head of the hook needle 4g ​​is downward, and the side wall of the needle head is provided with a hook thread barb, and the top of the barb is a plane.

[0068] The head main shaft 2 drives the hook thread cam 4a to rotate, and the hook thread cam 4a drives the hook thread rocker arm 4b to swing back and forth around the axis of the hinge shaft. The front end of the hook thread rocker arm 4b drives the hook thread middle lever 4d to swing back and forth around its own hinge shaft through the hook thread pull rod 4c. The front end of the hook thread middle lever 4d pulls the hook needle seat 4f to make up and down reciprocating motion along the hook thread guide rail 1b through the hook thread lower pull rod 4e, and the hook needle seat 4f drives the hook needle 4g ​​to make up and down reciprocating motion.

[0069] When the hook 4g moves downward, the barb can slide over the nylon thread 12a extending laterally below, and the hook 4g passes the lower dead point and starts to return upward, and the barb on the side of the hook 4g hooks the nylon thread 12a and lifts it upward, so that the single nylon thread 12a forms a double-stranded thread with an opening downward. The nylon thread 12a can be replaced by other high-strength threads.

[0070] Since the double strands of wire are close to each other, it is not convenient to put the bristles in. Therefore, the distance between the double strands of wire needs to be opened through an opening driving mechanism to facilitate the putting of the bristles in.

[0071] The opening drive mechanism includes an opening cam 5a, an opening rocker arm 5b, an opening pull rod 5c and an opening block 5d. The opening block 5d is C-shaped. The fixed end of the opening block 5d, i.e., the upper end of the C-shape, is hinged on the head bracket 1. The free end of the opening block 5d is provided with an opening conical head 5d1, and the tip of the opening conical head 5d1 faces forward.

[0072] The opening cam 5a is installed on the machine head main shaft 2, and an opening rocker arm 5b is meshed on the circumference of the opening cam 5a. The root of the opening rocker arm 5b is hinged on the machine head bracket 1, and the front end of the opening rocker arm 5b is hinged with an opening pull rod 5c, and the lower end of the opening pull rod 5c is hinged to the middle of the opening block 5d.

[0073] The machine head main shaft 2 drives the opening cam 5a to rotate, and the opening cam 5a drives the opening rocker arm 5b to swing around the axis of the hinge shaft. The front end of the opening rocker arm 5b pulls the opening pull rod 5c to reciprocate up and down, and the lower end of the opening pull rod 5c drives the opening block 5d to reciprocate around the hinge shaft at the upper end.

[0074] When the hook 4g hooks the nylon thread 12a to form a double-stranded thread upward, the open cone head 5d1 of the opening block 5d rotates forward and is inserted between the double-stranded threads. As the open cone head 5d1 continues to move forward, the opening between the double-stranded threads gradually increases. When the widest part of the root of the open cone head 5d1 is fully inserted, the opening between the double-stranded threads reaches the maximum and is pushed away from the barb by the open cone head 5d1. The top of the barb is a plane, which is convenient for the nylon thread 12a to be unhooked. The bristles are placed in the opening of the unhooked nylon thread 12a by the manipulator, which is convenient for the next process to embed the bristles into the eyelet.

[0075] A plurality of spindle signal wheels 2c are installed at one end of the machine head spindle 2 near the hand wheel 2b, and a spindle signal switch 2d corresponding to each spindle signal wheel 2c is installed on the machine head bracket 1. The spindle signal wheel 2c can be used to determine the angle of the machine head spindle 2 and the phases of the hair planting cam 3a, the hooking cam 4a and the opening cam 5a on the spindle 2. When the spindle signal switch 2d is triggered by the spindle signal wheel 2c, a start signal is sent to the take-up servo motor 21, the workbench, the manipulator, etc.

[0076] like Figures 6 to 10 As shown, the wire feeding machine includes a wire feeding frame 11, on which a wire spindle, a wire pressing mechanism, a wire taking-up mechanism, a gravity buffer mechanism and a three-way wire position adjustment mechanism are installed. A nylon wire 12a is wound around the wire spindle, and the wire spindle can rotate around its own axis to release the nylon wire 12a, and the nylon wire 12a passes through the wire pressing mechanism, the wire taking-up mechanism, the gravity buffer mechanism and the three-way wire position adjustment mechanism in sequence.

[0077] The gravity buffer mechanism includes a floating block 13a and a floating block guide rail 13c. A plurality of floating block guide wheels 13b are installed horizontally on the floating block 13a. The floating block guide rail 13c is installed on the wire feeding frame 11 and extends vertically. The back of the floating block 13a is supported on the floating block guide rail 13c by a slider and can slide up and down along the floating block guide rail 13c. The floating block guide rail 13c is fixed on the wire feeding frame 11.

[0078] An upper buffer pad 13d is embedded on the top of the floating block 13a, and an upper limit plate 11a fixed on the wire feeding frame is provided above the upper buffer pad 13d. A lower buffer pad 13e is embedded on the bottom of the floating block 13a, and a lower limit block 11b fixed on the wire feeding frame is provided below the lower buffer pad 13e, which not only limits the upper and lower positions of the floating block 13a but also avoids impact.

[0079] The wire-receiving mechanism includes a wire-receiving servo motor 21 and a swing arm 22. The wire-receiving servo motor 21 is fixed on the wire feeding frame 11. The root of the swing arm 22 is fixed on the conveying shaft of the wire-receiving servo motor 21 through a swing arm clamp. The swing arm 22 extends obliquely upward and is equipped with multiple sets of swing arm guide wheels 22b. The axes of each swing arm guide wheel 22b and each floating block guide wheel 13b are parallel to each other. The nylon wire 12a first passes around the first swing arm guide wheel from bottom to top, then passes around the first floating block guide wheel downward, and then passes around the second swing arm guide wheel upward, and thus alternately passes around each swing arm guide wheel 22b and the floating block guide wheel in an S shape.

[0080] The nylon line 12a suspends the weight of the floating block 13a during the forward movement. When the tension of the nylon line 12a is too high, the floating block 13a moves upward along the floating block guide rail 13c; when the tension of the nylon line 12a is too low, the floating block 13a falls along the floating block guide rail 13c. Since the weight of the floating block 13a remains constant, the nylon line 12a can always maintain a suitable tension.

[0081] The bottom of the floating block 13a is embedded with a lower buffer pad 13e, and a lower limit block 11b is provided below the lower buffer pad 13e. When the floating block 13a falls to the bottom, the lower buffer pad 13e contacts the lower limit block 11b to buffer the impact force generated by the falling floating block 13a. The top of the floating block 13a is embedded with an upper buffer pad 13d, and an upper limit plate 11a is provided above the upper buffer pad 13d. The upper limit plate 11a and the lower limit block 11b are respectively fixed on the wire feeding frame 11. When the floating block 13a rises to a high position, the upper buffer pad 13d presses against the lower end surface of the upper limit plate 11a to avoid hard impact.

[0082] When the nylon line 12a drawn from the wire spindle 12 is fed forward, the free end of the swing arm 22 is in a low position. When the front end of the nylon line 12a passes through the small hole at the bottom of the brush plate countersunk hole and forms a coil above the brush plate, a bunch of bristles is placed in the coil. At this time, the winding servo motor 21 drives the swing arm 22 to rotate a certain angle, the free end of the swing arm 22 rises upward, the distance between the swing arm guide wheel 22b and the floating block guide wheel 13b is enlarged, and the nylon line 12a in front is pulled back and stored. The coil of the nylon line 12a is gathered and the middle part of the bristles is bounded to pull the bristles into the bottom of the brush plate countersunk hole, thus completing the winding and bristle planting action.

[0083] When the wire-reeling servo motor 21 drives the swing arm 22 to reel in the wire, in order to prevent the nylon wire 12a on the wire spindle 12 from continuing to unwind, the upstream nylon wire 12a needs to be pressed down.

[0084] A swing arm cam 22a is provided on the swing arm clamp, and a lower pressure block roller 23a is engaged above the swing arm cam 22a. The lower pressure block roller 23a is fixed to the lower part of the lower pressure block bracket 23. The rear side of the lower pressure block bracket 23 is supported on a lower pressure block guide rail 11c extending vertically through a slider, and the lower pressure block guide rail 11c is fixed on the wire feeding frame 11; a lower pressure block 23b is fixed to the top of the lower pressure block bracket 23, and an upper pressure block 24 is provided above the lower pressure block 23b, and the nylon wire 12a passes between the upper pressure block 24 and the lower pressure block 23b.

[0085] When the swing arm 22 swings upward, the swing arm cam 22a on the swing arm clamp pushes the lower pressing block bracket 23 upward through the lower pressing block roller 23a, and the lower pressing block bracket 23 slides upward along the lower pressing block guide rail 11c, and the lower pressing block 23b floats up and clamps the nylon line 12a together with the upper pressing block 24. The swing arm 22 continues to swing upward, and the circumferential height of the swing arm cam 22a can remain unchanged or slightly increase, and the lower pressing block 23b and the upper pressing block 24 keep pressing the nylon line 12a, and each swing arm guide wheel 22b completes the line collection.

[0086] A swing arm signal plate 22c is installed on the swing arm 22, and a swing arm induction switch 27 is installed on the wire feeding frame 11. When the lower edge of the swing arm signal plate 22c just triggers the swing arm induction switch 27, the position of the swing arm 22 is set to zero position at this time.

[0087] The swing arm signal plate 22c is provided with a pair of arc grooves, which are symmetrically distributed with the axis of the output shaft of the take-up servo motor 21 as the center, and screws pass through the arc grooves to fix the swing arm signal plate 22c on the swing arm 22. In this way, it is convenient to adjust the position and angle of the swing arm signal plate 22c on the swing arm 22, so that the adjustment of the swing arm zero position is more accurate.

[0088] One side of the upper pressing block 24 is hinged on the wire feeding frame 11, and the two ends of the upper pressing block 24 are embedded in the grooves on the top of the wire feeding frame 11. When the lower pressing block 23b floats up against the upper pressing block 24, the weight of the upper pressing block 24 can fall completely on the nylon line 12a, and the working position will not deviate. The two ends of the upper pressing block 24 are respectively connected with counterweight blocks 24a to increase the weight of the upper pressing block 24 and maintain appropriate pressure on the nylon line 12a. In this way, reliable wire pressing can be ensured, which is convenient for wire winding, and excessive wire winding tension can be prevented, so that the nylon line 12a is prevented from being broken.

[0089] A pair of one-way needle roller bearings 25 for clamping the nylon line 12a are respectively provided upstream and downstream of the line pressing section between the upper pressing block 24 and the lower pressing block 23b. The two pairs of one-way needle roller bearings 25 are respectively arranged at the turning points of the nylon line 12a, clamping the nylon line 12a from both sides, only allowing the nylon line 12a to move forward, and not allowing it to move backward. A guide wire eye 26 is respectively provided between each pair of one-way needle roller bearings 25 and the line pressing section to ensure the stability of the nylon line 12a moving forward.

[0090] The three-way line position adjustment mechanism includes a front and rear adjustment angle bracket 14 fixed on the wire feeding frame 11, and a front and rear long groove 14a is provided on the horizontal side of the front and rear adjustment angle bracket 14. The screw passes through the front and rear long groove 14a to fix the front and rear adjustment angle bracket 14 on the wire feeding frame 11. The position of the front and rear adjustment angle bracket 14 relative to the wire feeding frame 11 in the front and rear direction can be adjusted through the front and rear long groove 14a.

[0091] An up-and-down adjustment plate 15 is fixed to the vertical wall of the front-and-rear angle adjustment bracket 14 , and a vertical long slot is provided in the middle of the up-and-down adjustment plate 15 to facilitate the adjustment of the position of the screw to change the height of the up-and-down adjustment plate 15 .

[0092] A left-right adjustment bracket 16 is installed on the up-down adjustment plate 15 . The left-right adjustment bracket 16 is Z-shaped, and a long slot extending in the left-right direction is provided at the lower end. Screws pass through the long slot to fix the bottom of the left-right adjustment bracket 16 to the upper corner of the up-down adjustment plate 15 .

[0093] Fixed-axis wire wheels 17 for steering the nylon wire 12a are installed at both ends of the upper and lower adjustment plates 15 in the horizontal direction, and two horizontal threading sleeves 18 are arranged between the two fixed-axis wire wheels 17. The two horizontal threading sleeves 18 are fixed to the front end surface of the upper and lower adjustment plates 15 through threading sleeve fixing blocks 18a.

[0094] An L-shaped fixing block 19 is fixed below the head end of the upper and lower adjustment plate 15 . The horizontal side of the L-shaped fixing block 19 faces upward and is installed with a vertical threading sleeve 20 . A pair of fixed-axis wire wheels 17 are installed on the vertical wall of the L-shaped fixing block 19 .

[0095] A line-out wheel 16a is installed on the upper part of the left and right adjustment brackets 16, and a tungsten steel rod 16b is installed above the line-out wheel 16a. After the nylon line 12a is led out from the line-out wheel 16a, it is pressed under the tungsten steel rod 16b and extends toward the hair implanting station. The axis of the tungsten steel rod 16b is parallel to the line-out wheel 16a and extends in the horizontal direction.

[0096] A pair of cylindrical pins 16d parallel to each other and extending vertically are also provided downstream of the tungsten steel rod 16b. The nylon line 12a passes between the two cylindrical pins 16d. The bottoms of the two cylindrical pins 16d are fixed on the cylindrical pin fixing block 16c, and the cylindrical pin fixing block 16c is fixed on the left and right adjustment brackets 16.

[0097] The nylon wire 12a led out from the floating block guide wheel 13b first passes upward through a pair of fixed-axis wire wheels 17 on the vertical wall of the L-shaped fixed block 19, then continues to pass upward through the center hole of the vertical threading sleeve 20, then bypasses the fixed-axis wire wheel 17 at the head end of the upper and lower adjustment plates 15 to turn to the horizontal direction, passes through the center holes of the two horizontal threading sleeves 18, bypasses the fixed-axis wire wheel 17 at the tail end of the upper and lower adjustment plates 15, turns upward, and bypasses the outlet wheel 16a in an S shape; the tungsten steel rod 16b and the outlet wheel 16a are limited above and below the nylon wire 12a, and the two cylindrical pins 16d are limited before and after the nylon wire 12a, to ensure that the nylon wire 12a is always stable and avoids shaking when moving toward the hair transplanting station.

[0098] Each fixed-axis wire wheel 17 and the floating block guide wheel 13b can adjust the pressure on the nylon line.

[0099] like Fig.11 As shown, taking the fixed-axis wire wheel 17 as an example, it includes a fixed wheel piece 17a, a floating wheel piece 17b and a wire wheel screw 17c. The inner hole of the fixed wheel piece 17a is supported on the bare rod section of the wire wheel screw 17c through a radial ball bearing 17d. The outer ring of the radial ball bearing 17d is limited by a hole retaining ring 17e. The hole retaining ring 17e is embedded in the annular groove of the inner hole of the fixed wheel piece. The inner ring of the radial ball bearing 17d is abutted against a shaft sleeve 17f. The end surface of the shaft sleeve 17f and the hexagonal head of the wire wheel screw 17c are clamped on both sides of the mounting plate, so that the fixed-axis wire wheel 17 is fixed on the mounting plate.

[0100] The center hole of the floating wheel 17b is mounted on the smooth rod section of the wire wheel screw 17c, and the countersunk hole of the floating wheel 17b facing the fixed wheel 17a is mounted on the fixed wheel convex ring. A wire gap is left between the facing end faces of the fixed wheel 17a and the floating wheel 17b. The width of the wire gap is slightly smaller than the diameter of the nylon wire 12a. The nylon wire 12a is embedded in the wire gap and is clamped on both sides by the facing end faces of the floating wheel 17b and the fixed wheel 17a. The facing end faces of the floating wheel 17b and the fixed wheel 17a are respectively provided with chamfers, and a V-shaped groove is formed at the outer end of the wire gap to facilitate the nylon wire 12a to slide into the wire gap.

[0101] The outer end surface of the floating wheel 17b is pressed with a three-peak washer 17g, and the outer side of the three-peak washer 17g is pressed with a thrust ball bearing 17h. The outer end surface of the thrust ball bearing 17h is pressed against a wire wheel nut 17j, and the wire wheel nut 17j is screwed on the threaded section of the wire wheel screw 17c. There are usually two wire wheel nuts 17j, and the two wire wheel nuts 17j are provided with elastic washers. On the one hand, when the nylon line 12a moves forward, it can drive the fixed wheel 17a and the floating wheel 17b to rotate freely synchronously. On the other hand, under the elastic action of the three-peak washer 17g, the floating wheel 17b has a certain elasticity in the axial direction, which is convenient for adjusting the clamping force on the nylon line 12a.

[0102] The threading and hair transplanting method of the present invention comprises the following steps in sequence:

[0103] S1, manually tie the end of the nylon thread 12a to a hole of the brush plate 10, and the nylon thread 12a passes under the hole to be planted;

[0104] S2, the workbench moves the brush plate 10 so that the holes of the brush plate 10 to be planted are coaxial with the tubular hair nozzle 3f and the hook needle 4g;

[0105] S3, the hair planting slide 3d drives the bristle nozzle platform 3e and the tubular bristle nozzle 3f to move downward, and the hook needle seat 4f moves downward with the hook needle 4g ​​at the same time. During the downward movement of the tubular bristle nozzle 3f, the tension of the torsion spring 6b is overcome, and the plucking plate 6c is pushed open. The plucking plate 6c passively rotates downward to pry the bristles below;

[0106] S4, the hair planting slide 3d drives the hair nozzle platform 3e downward, and stops when the lower end of the tubular hair nozzle 3f is close to the hair planting hole of the brush plate 10 by 1mm. The distance between the lower end of the tubular hair nozzle 3f and the top of the brush plate can also be adjusted according to the situation;

[0107] S5, the hook 4g continues to move downward, passes through the lower end of the tubular hair nozzle 3f and the hole to be planted, and the nylon thread 12a is pushed aside by the sharp conical surface of the lower end of the hook 4g, and the hook 4g continues to move downward until the barb of the hook side wall is lower than the nylon thread 12a, at which time the nylon thread 12a rebounds and sticks to the top of the barb of the hook 4g; because the end of the nylon thread 12a has been fixed in a brush hole, the pay-off end of the nylon thread 12a is kept taut by the gravity buffer mechanism;

[0108] S6, the tubular hair nozzle 3f remains stationary, the hook 4g returns upward, the barb hooks the nylon line 12a and hooks it out from the eyelet to be planted and the tubular hair nozzle 3f, forming a double-stranded line with an opening downward above the hair nozzle platform 3e; during the hooking process, the wire feeder releases the nylon line 12a and maintains tension;

[0109] S7, the opening block 5d rotates forward, so that the tip of the opening cone head 5d1 is inserted forward between the double strands of the hook 4g, so that they are separated from each other to form an opening; as the opening cone head 5d1 continues to be inserted, the coil of the opening expands, and when the opening cone head 5d1 is inserted to the root and contacts the nylon line 12a, the opening of the nylon coil is the largest, and at this time the upper end of the coil is separated from the hook of the hook 4g;

[0110] S8, the robot inserts a bunch of bristles into the coil and releases it into the bristle placing groove 3e1 of the bristle nozzle platform 3e, and then the robot withdraws;

[0111] S9, the opening block 5d rotates backward, and the opening cone head 5d1 exits the coil backward;

[0112] S10, the wire feeding machine gathers the nylon wire 12a so that the coil covers the bristles, and continues to gather so that the bristles are folded from the middle to form a U shape, and are dragged into the bristle feeding channel of the bristle nozzle platform 3e and the central hole of the tubular bristle nozzle 3f by the nylon wire 12a; the nylon wire 12a is continued to be gathered, and the roots of the bristles are dragged into the large hole step of the bristle planting hole of the brush plate and fixed;

[0113] S11, the hair mouth platform 3e and the hook 4g return upward, and the hair plucking plate 6c is reset by the torsion spring 6b;

[0114] S12, the workbench moves the next hole to be planted with hair of the brush plate 10 to the hair planting station, and repeats S3 to S11, and the cycle is repeated until the hair planting of all the holes is completed. The nylon thread 12a is tied to the root formed by the folded part of each bundle of bristles in each hole in an Ω shape.

[0115] The specific actions of the wire feeding machine to gather the nylon wire 12a in step S10 are as follows:

[0116] The take-up servo motor 21 drives the swing arm 22 to rotate upward, and the swing arm cam 22a drives the lower pressing block bracket 23 and the lower pressing block 23b to rise through the lower pressing block roller 23a, and the lower pressing block 23b lifts the upper pressing block 24, and the weight of the upper pressing block 24 presses the nylon line 12a between the two pairs of one-way needle bearings 25;

[0117] The take-up servo motor 21 drives the swing arm 22 to continue to rotate upward, and the distance between the swing arm guide wheel 22b and the floating block guide wheel 13b is enlarged, so as to pull back and store the nylon line 12a hooked by the hook needle 4g;

[0118] When the root of the bristle reaches the large hole step of the hair planting eyelet, the wire-receiving servo motor 21 drives the swing arm 22 to continue to rotate upward, and the nylon wire 12a drives the floating block 13a of the gravity buffer mechanism to rise, and the weight of the floating block 13a tightens the nylon wire 12a.

[0119] The entire brush plate 10 can be planted with a continuous nylon thread. When the bristles are worn, the nylon thread is cut into several pieces, and the bristles are no longer restricted. The nylon thread can be pulled out in sections, or the bristles can be directly pulled out. No residue will be left in the holes, and no rusty substances will be left. The brush plate 10 is usually a plastic part and will not be damaged or worn during operations such as polishing. After the bristles are pulled out, the bristles can be planted repeatedly for an unlimited number of times, which greatly reduces the cost of accessories and polishing.

Manually tie the end of the nylon thread to a hole of the brush plate, and the nylon thread passes under the hole to be planted; S2, the workbench moves the brush plate so that the holes to be planted on the brush plate are coaxial with the tubular hair nozzle and the hook; S3, the tubular hair nozzle and the hook needle move downward at the same time, and the plucking plate is pushed away during the downward movement of the tubular hair nozzle, and the plucking plate passively rotates downward to perform the plucking action; S4, the lower end of the tubular hair nozzle stops when it is close to the hole to be planted on the brush plate; S5, the hook continues to move downward, passing through the lower end of the tubular hair nozzle and the hole to be planted, so that the barb on the hook reaches below the nylon line; S6, the tubular hair mouth remains stationary, the hook returns upward, the barb hooks the nylon line and hooks it out of the eyelet to be planted and the tubular hair mouth, forming a double-strand line with an opening downward above the hair mouth platform; During the hooking process, the wire feeder releases the nylon wire; S7, the opening block rotates forward, so that the tip of the opening cone head is inserted forward between the double strands under the crochet hook, so that they are separated from each other to form an opening; as the opening cone head continues to be inserted, the loop of the opening expands and detaches from the hook of the crochet hook; S8, the manipulator inserts a bunch of bristles into the coil and releases it into the bristle placement groove of the bristle nozzle platform, and then the manipulator withdraws; S9, the opening block rotates backward, and the opening conical head exits the coil backward; S10, the wire feeding machine gathers the nylon wire so that the coil covers the bristles, and continues to gather so that the bristles are folded from the middle to form a U shape, and are pulled into the feeding hole of the bristle nozzle platform and the central hole of the tubular bristle nozzle by the nylon wire; the nylon wire is continued to be gathered, and the roots of the bristles are pulled into the large hole step of the bristle planting hole of the brush plate and fixed; S11, the hair mouth platform and the hook return upward and reset, and the hair plucking plate is reset by the torsion spring; S12, the workbench moves the next hole to be transplanted with hair on the brush plate to the transplanting station, and repeats S3 to S11, and the cycle continues until the transplanting of hair on all holes is completed.

10. The threading and hair transplanting method according to claim 9, characterized in that: The specific actions of the wire feeding machine to gather the nylon wire in step S10 are as follows: The wire-reeling servo motor drives the swing arm to rotate upward, and the swing arm cam drives the lower pressure block bracket and the lower pressure block to rise through the lower pressure block roller. The lower pressure block lifts the upper pressure block, and the weight of the upper pressure block presses the nylon wire at the outlet of the wire spindle; The wire-retrieving servo motor drives the swing arm to continue to rotate upward, and the distance between the swing arm guide wheel and the floating block guide wheel is enlarged, so that the nylon wire hooked by the hook is pulled back and stored; When the root of the bristle reaches the large hole step of the hair planting eyelet, the wire-reeling servo motor drives the swing arm to continue to rotate upward, and the nylon wire drives the floating block of the gravity buffer mechanism to rise, and the weight of the floating block tightens the nylon wire.
