Description

Technical Field

[0001] This invention belongs to the field of hairdressing equipment, and in particular relates to an intelligent self-service men's flat-top hairdressing device and its hairdressing operation method. Background Technology

[0002] With residents unable to leave their homes for extended periods and barbershops closed, men's haircuts have become a major problem. Currently, many large supermarkets have set up simple barbershops offering haircuts for 10-15 yuan per session, without shampooing. These shops attract a large number of customers, with long queues frequently seen. Based on this situation, there is a very broad social demand for intelligent self-service men's haircut devices.

[0003] Furthermore, some industries require men to have short haircuts, such as soldiers, workers in special occupations, and the majority of elderly people, all of whom are men with buzz cuts. For such a large population, if a self-service haircutting machine could replace manual haircuts, it would significantly increase efficiency and reduce labor costs. Therefore, the demand for intelligent self-service men's buzz cut haircutting devices is enormous.

[0004] However, in today's society, there are no such intelligent self-service hairdressing devices. Even if there are some technological explorations (such as some patent applications), these technologies suffer from problems such as immaturity, high cost, poor practicality, inconvenience in operation, and some even require specialized hairdressers to operate them. As a result, they cannot achieve the purpose of self-service hairdressing, nor can they be converted into finished products. Therefore, they cannot meet the needs of society for intelligent self-service hairdressing. Summary of the Invention

[0098] I. Haircutting Procedure

[0099] In this embodiment, the operation method of the intelligent self-service men's flat-top haircut device includes: head fixation, head shape detection, and haircut control. Head fixation is achieved through an earplug-type head fixation device 4 and an eye mask-type head fixation device 5. This ensures that when the user's head experiences slight up-and-down, left-and-right, and back-and-forth movement during the haircutting process, the positions of the detection and haircutting device components relative to the user's head remain stable. Head shape detection involves a mechanical probe within the head shape detection device 1 contacting the user's head and employing point-by-point scanning technology to acquire head shape data for different users. Haircut control involves controlling the haircutting blades according to the head shape data detected by the head shape detection device 1, using instantaneous movement technology to control the blades' advance and retreat, thereby achieving the desired haircut. In actual use, the operation of the haircutting device and the corresponding mechanism operation specifically include the following steps:

[0100] Step 1: Power on:

[0101] Operation: Press the power button to supply power to the main power supply of the intelligent self-service men's haircut device.

[0102] Hair cutting device operation: All electrical components are powered on, the probes on the five semi-circular detection heads of the head shape detection device open and close, and stop when they are touched by a micro switch.

[0103] Step Two, Head Stabilization Step One:

[0104] Operation: The user sits on the barber chair, pulls down the barber head cover, inserts the left and right earplugs of the earplug-type head fixing device 4 into the ear canals, and presses the control switch of the locking rod controller of the earplug-type head fixing device 4.

[0105] Hairdressing device operation: After the control switch of the locking rod controller is closed, the PLC control 63 in the hairdressing control device 2 powers the electric suction cup of the locking rod controller, causing the two locking plates of the electric suction cup to retract inward, clamping and fixing the earplug support rod.

[0106] Step 3, Head Stabilization (Step 2):

[0107] Operation: The user lifts the eye mask head fixation device 5, places it against the forehead, and presses the locking switch.

[0108] Hairdressing device operation: After the locking switch of the eye mask type head fixing device 5 is pressed, the locking mechanism will lock and fix the fixing device.

[0109] Step 4: Start the haircut:

[0110] Operation: The user presses the start haircut button.

[0111] Hair clipper in operation:

[0112] Step 1: Head Shape Detection

[0113] 1. Under the control of the PLC controller 63, the five detection head probes on the head shape detection device 1 extend to the lowest part of the back half of the user's head, stop when they are close to the head, and remain in close contact with the head.

[0114] 2. Under the control of the PLC controller 63, the detection platform 11 of the head shape detection device 1 begins to rotate from the lower rear of the head to the upper front of the head. Simultaneously, it drives the five detection head probes to rotate around the head along five directional routes. The detection function of the detection heads is activated simultaneously, and the head shape data is transmitted to the PLC controller 63 for storage.

[0115] 3. When the detection platform 11 of the head shape detection device 1 runs to the front end of the head, the head shape data has been completely stored. At this time, the PLC controller 63 stops the operation of the detection platform and controls the five detection head probes to open again and stop when they touch the micro switch.

[0116] Step 2, Haircut Control:

[0117] 1. After the head shape detection step is completed, the hair cutting control step will start automatically.

[0118] 2. Under the control of the PLC controller, the seven stepper motor lead screw slides on the hair clipper platform 21 extend towards the lowest part of the back of the user's head and stop when they are close to the head.

[0119] 3. Under the control of the PLC controller 63, the hair-cutting platform 21 begins to rotate from the lower back of the head to the upper front of the head. Simultaneously, it drives the seven stepper motor lead screw slide hair clippers to rotate around the head along seven different directions. At this point, the stepper motor lead screw slide hair clippers start and, according to the control of the PLC controller 63, trim the user's hair.

[0120] 4. When the hair-cutting platform 21 reaches the front of the head, the hair-cutting process is completed. At this time, the PLC controller 63 stops the operation of the hair-cutting platform 21 and the stepper motor, lead screw, slide table, and hair clipper.

[0121] Step 3, Platform Recycling:

[0122] 1. Once the haircutting steps are completed, the process will automatically restart.

[0123] 2. Under the control of the PLC controller 63, the seven stepper motor lead screw slides on the hair clipper platform 21 retract to their initial positions. At the same time, the hair clipper platform 21 also begins to rotate back under the control of the PLC controller 63, stopping at its initial position.

[0124] 3. After the hairdressing platform 21 has completed its recycling process, the detection platform 11 will automatically begin recycling.

[0125] 4. The detection platform 11 rotates back to its initial position.

[0126] Step 4: End of haircut:

[0127] 1. After the detection platform 11 returns to its initial position, the haircutting process will automatically begin.

[0128] 2. The PLC controller 63 de-energizes the locking rod controller of the earplug-type head fixing device 5, releasing the locking clip.

[0129] 3. The user unlocks and pushes open the eye mask head restraint device 4, then pushes the support rod of the earplug head restraint device 4 to both sides, then pushes the head mask up, and gets up from the seat.

[0130] Step 5: Power off:

[0131] Operation: The user presses the power off button.

[0132] Hair clipper in operation:

[0133] 1. Under the control of the PLC controller 63, the five detection probes on the detection platform 11 extend towards the initial center position and stop at the end point.

[0134] 2. The main power supply of the hairdressing device is disconnected under the control of PLC controller 63.

[0135] The experiments on the three technical methods of head fixation, head shape detection, and hair-cutting control in this invention have been completed and successfully conducted. In practical use, this invention can also add the function of controlling the power supply via WeChat QR code payment (existing technology) to facilitate the function of a shared hair-cutting machine. This will further stimulate the market development prospects of the hair-cutting device of this invention.

[0136] II. The operating principle of hairdressing:

[0137] In a preferred embodiment of the present invention, an intelligent self-service men's flat-top haircutting device includes a head shape detection device 1, a haircutting control device 2, a head cover frame structure 3, an earplug-type head fixation device 4, an eye mask-type head fixation device 5, an electrical control component box 6, and a hair clipping collection device 7. The head cover frame structure 3 includes a head cover assembly 31, a frame assembly 32, a counterweight assembly 33, and a base 34. The head cover assembly 31 and the counterweight assembly 33 are respectively installed on the top two sides of the frame assembly 32, and the bottom of the frame assembly 32 is installed on one side of the base 34. The electrical control component box 6 and the hair clipping collection device 7 are installed on the surface of the base 34. A haircutting chair 35 is installed on the electrical control component box. The head shape detection device 1, the haircutting control device 2, the earplug-type head fixation device 4, and the eye mask-type head fixation device 5 are installed inside the head cover assembly 31. The electrical control circuits of the head shape detection device 1, the haircutting control device 2, the earplug-type head fixation device 4, the eye mask-type head fixation device 5, and the hair clipping collection device 7 are all connected to the electrical control component box 6. In actual use, each moving part in this device (such as the hair clipper 22 and the detection probe 122) is equipped with a safety warning device. The safety warning device can be a photoelectric sensor. The photoelectric sensor is connected to the PLC controller 63. The purpose of the photoelectric sensor is to provide timely safety warnings. When a photoelectric sensor alarms, the PLC controller 63 controls the entire device to cut off power.

[0138] In this embodiment, the operating principle of the intelligent self-service men's flat-top barber device is as follows:

[0139] 1. Head immobilization:

[0140] a. Head fixation in the middle of the headgear:

[0141] The head-fixing device, consisting of an earplug-type head-fixing device 4 and an eye mask-type head-fixing device 5, ensures that the user's head is always fixed in the accurate haircutting position in the center of the head mask.

[0142] Its operating principle is as follows: When the user inserts the two earplugs into his / her ears, since the two earplugs are directly connected to the central axis of the detection platform 11 and the hair-cutting platform 21 through the earplug support rod 42, the lateral position of the user's head is aligned with the position of the central axis of the detection platform 11 and the hair-cutting platform 21. Afterwards, when the user starts the hair-cutting device, the two electronic rulers of the two earplug-type head fixing devices 4 send data to the PLC controller 63. If the two data are inconsistent, it means that the user's head is not in the middle position, that is, the distance between the user's two ears and the frame of the LU-shaped bracket 313 on both sides is inconsistent. At this time, the computer of the PLC controller 63 will analyze the data of the two electronic rulers 46, calculate which side the head is closer to and which side is farther away, and then calculate the running data of the stepper motor lead screw slide 43 in the two earplug-type head fixing devices 4. The two stepper motor drivers drive the slide on the stepper motor lead screw slide 43 to move synchronously, moving the user's head to the middle position of the head cover body 311, that is, the accurate position for hair cutting between the detection platform 11 and the hair-cutting platform 21.

[0143] b. Fixing the head during slight shaking:

[0144] Because the headgear has a suspending and balancing function, it ensures that when the user's head shakes slightly, whether up and down, forward and backward, or left and right, the internal components of the headgear remain stable and will not become misaligned.

[0145] Its operating principle is as follows: Since the headgear is suspended in the air, slight back-and-forth and side-to-side swaying of the headgear has no effect on anything inside it. The headgear's balancing device (counterweight component 33), that is, the weight of the pendant, is almost exactly the same as the headgear itself. Therefore, slight up-and-down movement of the headgear will not cause any internal components to shake. Thus, when the user sits on the barber's chair 35, the user's head will not shake much unless they deliberately stand up or shake it violently. Otherwise, under normal haircutting conditions, the headgear will not shake much enough to cause the user's head to detach from it.

[0146] 2. Head shape detection:

[0147] The head shape detection device 1 uses the rotation of the detection platform 11 to drive several detection probes to detect different positions of different barbers' heads, obtain head shape detection data, and store the detection data in the memory of the PLC controller 63.

[0148] Its operating principle is as follows: When detection is activated, the several detection probes 122 already extended on the detection platform 11, under the control of the PLC controller 63, extend together towards the barber's head and stop upon contact. At this time, the detection platform 11 begins to rotate, and the conductive plastic potentiometer 1213 inside the detection head 121 is also powered. Driven by the detection platform 11, the several detection probes 122 move along several directions of the head, starting from the lower back of the barber's head, moving upwards and forwards. During the movement, due to the different heights of the head contour, the detection probes 122 move up and down accordingly. At this time, the conductive plastic potentiometer 1213, connected to the detection probes 122 via gears, sends out different voltage signals. These continuous voltage signals are the source of head shape data and are directly sent to the head shape data input terminal of the PLC controller 63. Although the head shape information transmitted from the detection head 121 to the PLC controller 63 is a continuous voltage signal, within the PLC controller 63, through computer calculation, the information from one detection head 121 is transformed into more than four hundred different data points, which are stored in the dedicated memory within the PLC controller 63. Thus, the entire head shape data detected by the head shape detection device 1 is formed. The longest detection probe 122 travels approximately 450 millimeters. If one data point is set per millimeter, then the head shape information output by each detection probe 122 within the PLC controller 63 requires approximately 450 memory units. Therefore, five detection probes 122 would require 2500 memory units.

[0149] 3. Hairdressing control:

[0150] The haircutting control device 2 is the computer of the PLC controller 63. By calculating and integrating the head shape detection data, it outputs control data to the stepper motor lead screw slide 43 that drives the hair clipper 22. As the haircutting platform 21 rotates, the hair clipper 22 pushes towards the hairdresser's head from different angles, thereby completing the haircutting of the user's head shape.

[0151] Its operating principle is as follows: When the hair-cutting control device 2 is started, the computer in the PLC controller 63 processes the head shape data transmitted from the head shape detection device 1 and integrates it with the standard head shape data to form control data for the operation of the stepper motor lead screw slide 43 on the hair-cutting platform 21. This data, driven by the driver of the stepper motor lead screw slide 43, drives the operation of the hair clippers 22. Initially, the hair clippers 22 are pushed from the lower back of the user's head to a position where they contact the head. Then, the hair-cutting platform 21 is started and the hair clippers 22 are powered according to the program. While the hair-cutting platform 21 is operating, the hair clippers 22 are controlled by the PLC controller 63, causing them to move according to the hair-cutting control data, thus cutting the hair on the head.

[0152] III. Self-service usage method:

[0153] Before starting the hair-cutting device, first check if the user's hair is too long. Generally, the hair on the side and back of the user's head should not be longer than 1 cm. If it is too long, the hair-cutting device will not be able to complete the hair-cutting process.

[0154] 1. The user sits on the barber chair 35;

[0155] 2. Raise your hand and pull down the barber's head cover (head cover body 311);

[0156] 3. Insert the earplug of the earplug-type head fixing device 4 into the ear canal and tighten the ear protection plate;

[0157] 4. Lift the blindfold-style head restraint device 5 and place it in front of your eyes and on your forehead, then tighten it securely;

[0158] 5. Turn on the haircut start switch;

[0159] 6. The hair-cutting device performs the detection and hair-cutting procedure, and the entire hair-cutting process is completed in approximately 3-5 minutes;

[0160] 7. Loosen the blindfold-type head fixation device 5 and the earplug-type head fixation device 4, push the barber's head cover upwards, and stand up to finish the haircut.

[0161] IV. Detailed Description of the Hairdressing Device Structure

[0162] In a preferred embodiment of the present invention, the head cover assembly 31 includes a head cover body 311, a head cover shell 312, and an LU-shaped bracket 313. The top of the head cover body 311 is connected to the frame assembly 32, and the top of the head cover body 311 is also connected to the hair clipping collection device 7 (the ventilation hose of the hair clipping collection device 7, i.e., the gas branch pipe, exits from the hair clipping collection device 7 at the rear of the barber chair 35 through the main support frame 321, extends along the main support frame 321 to the top fixing frame 322, and enters the head cover body 311 from the top fixing frame 322, and then...). The top of the head cover body 311 extends to the hair-cutting platform 21, and then through the air distribution groove of the hair-cutting platform 21, it leads to the front end of each hair clipper 22. The bottom of the head cover body 311 is connected to the head cover shell 312. The head cover shell 312 has a U-shaped structure. An LU-shaped bracket 313 is installed inside the head cover shell 312. An eye mask-type head fixing device 5 is installed on one side of the LU-shaped bracket 313. An earplug-type head fixing device 4 is installed at each end of the LU-shaped bracket 313. The two ends of the LU-shaped bracket 313 are also connected to the head shape detection device 1 and the hair-cutting control device 2, respectively.

[0163] In a preferred embodiment of the present invention, the LU-shaped bracket 313 includes a U-shaped frame 3131, two L-shaped brackets 3132 and two platform central shafts 3133. The two L-shaped brackets 3132 are respectively installed on both sides of the U-shaped frame 3131. Each L-shaped bracket 3132 is equipped with a platform central shaft 3133 by bearings. The two platform central shafts 3133 are respectively connected to the head shape detection device 1, the hairdressing control device 2, the earplug-type head fixing device 4, and the eye mask-type head fixing device 5. The U-shaped frame 3131 is installed inside the head cover housing 312.

[0164] like Figure 16 The diagram shows the central shafts of the two platforms, the platform running motors, and the connecting gear flange bearings. A bearing, similar to the platform connecting bearing, is located at the position of the LU-type bracket 313 and is used for fixed connection to the LU-type bracket 313. All components in the diagram are devices at one end of the LU-type bracket 313; the same set of devices exists at the other end of the LU-type bracket 313. The difference is that one end of each platform's two end feet is connected to a flange, and the other end is connected to a bearing. Specifically, A refers to the LU bracket central shafts (two on the left and right), B refers to the gear sets (i.e., the two platform drive gear sets (two sets on the left and right)), C refers to the two platform running control stepper motors (i.e., the two platform drive stepper motors (two on the left and right)), D refers to the platform connecting flanges (i.e., the two platform connecting flanges to the central shaft (two on the left and right)), used to connect the detection platform 11; the platform connecting flanges are fixed to the platform via connecting plates, and E refers to the platform connecting bearings (i.e., the two platform connecting bearings to the central shaft (two on the left and right)), used to connect the hairdressing platform 21; the platform connecting bearings are fixed to the platform via connecting plates.

[0165] In a preferred embodiment of the present invention, the frame assembly 32 includes a main support frame 321 and a fixing frame 322. The bottom of the main support frame 321 is connected to the base 34, and the top of the main support frame 321 is mounted to one side of the fixing frame 322. A counterweight assembly 33 is mounted on one side of the fixing frame 322, and a head cover assembly 31 is provided on one side of the fixing frame 322. The main support frame 321 is also connected to a hair clipping collection device 7. In this embodiment, the main support frame 321 can be an adjustable telescopic rod structure to match the height of the customer.

[0166] In a preferred embodiment of the present invention, the counterweight assembly 33 includes a configuration block 331 and a counterweight pulley assembly 332. The counterweight pulley assembly 332 is installed above the fixing frame 322. One end of the counterweight pulley assembly 332 is connected to the configuration block 33 via a sliding rope, and the other end is connected to the headgear body 311 via a sliding rope.

[0167] In this embodiment, the structure of the headgear assembly 31 is shown in the headgear outline drawing ( Figure 6), LU type bracket 313 bracket diagram ( Figure 7 ), Frame component 32 main support frame diagram ( Figure 8 ), base and seat diagram ( Figure 9 ).

[0168] The upper part of the hood structure (hood body 311) is a semi-circular body with an opening at the front, and the lower part is a cuboid body with an opening at the front (hood shell 312).

[0169] Inside the headgear (headgear body 311) is an LU-shaped bracket 313, which supports the detection platform 11 and the hairdressing platform 21. Earplug-type head fixation devices 4 are installed on the central axis of the two top ends of the U-shaped bracket of the LU-shaped bracket 313, and an eye mask-type head fixation device 5 is installed on the lower left end of the U-shaped bracket of the LU-shaped bracket 313.

[0170] The frame assembly 32 includes a main support frame 321 and a headgear balancing device (fixed frame 322).

[0171] The base 34 is a four-wheeled platform that can move. A barber's chair 35 is placed in the middle of the base. Below the barber's chair 35 is the electrical control component box 6.

[0172] The main support frame 321 is fixed at the middle of the rear edge of the base 34. The main support frame 321 is inverted L-shaped.

[0173] The headgear balancing device (fixed frame 322) works in conjunction with its top counterweight pulley assembly 332. The pulley at the front end of the fixed frame 322 is used to suspend the headgear assembly 31, and the pulley at the rear end of the fixed frame 322 is used to balance the headgear assembly 31's pendant (configuration block 331). The weight of the balancing pendant configuration block 331 is the same as the weight of the entire headgear assembly 31, and slightly more. This ensures that the headgear assembly 31 can move up and down very easily, and also ensures that the headgear assembly 31 can naturally stay at the top of the fixed frame 322 without external force.

[0174] In a preferred embodiment of the present invention, the hair clipping collection device 7 includes a vacuum cleaner 71, a main gas pipeline 72, a gas pipeline distributor, and several gas branch pipelines. The vacuum cleaner 71 is installed on one side of the base 34, and one side of the vacuum cleaner 71 is connected to one end of the main gas pipeline 72. The main gas pipeline 72 is installed on the main support frame 321, and the other end of the main gas pipeline 72 is connected to several gas branch pipelines in sequence through the gas pipeline distributor. The air intake of the gas branch pipelines is installed to the hairdressing control device 2, and the vacuum cleaner 71 is connected to the electrical control component box 6.

[0175] In this embodiment, the structure of the hair fragment recycling device 7 is shown in the hair fragment recycling device diagram (). Figure 15 , Figure 35 ).

[0176] The hair clipping collection device 7 includes a vacuum cleaner 71 placed on a base 34, a main gas line 72 connecting the vacuum cleaner 71 and the hair-cutting platform, a gas line distributor, and branch gas lines leading to each hair clipper head, as well as air intakes on each clipper head. When the hair-cutting process begins, the vacuum cleaner 71 is activated to collect the cut hair clippings. Figure 23 As shown, M refers to the wiring conduit between all electrical circuits inside the head cover assembly and the electrical control component box.

[0177] In actual use, the hair clipping device 7 on the hair clipping platform 21 is the main part of the entire hair clipping device. Hair clippings collected at the hair collection port above each clipper head are gathered at the conversion head of the hair clipping device 7 via a branch gas pipeline, and then connected to the vacuum cleaner on the base of the hair clipping device via a main gas pipeline. When the hair cutting process is started, the power supply box 64 supplies power to the vacuum cleaner of the hair clipping device 7 to complete the process.

[0178] In a preferred embodiment of the present invention, the electrical control component box 6 includes an electrical component box 61, a stepper motor driver 62, a PLC controller 63, and a power supply box 64. The top of the electrical component box 61 is provided with a barber chair 35. The power supply box 64 is placed inside the electrical component box 61. The stepper motor driver 62 and the PLC controller 63 are installed on one side of the power supply box 64. The stepper motor driver 62 is connected to the PLC controller 63. The stepper motor driver 62 and the PLC controller 63 are both electrically connected to the power supply box 64. In actual use, the stepper motor driver 62 is located in the stepper motor control box, and the PLC controller 63 is located in the PLC control box. The stepper motor driver 62 includes the driver for the stepper motor of the head shape detection device 1, the driver for the stepper motor of the barber control device 2, and the driver for the earplug stepper motor 433.

[0179] In this embodiment, the structure of the electrical control component box 6 is shown in the electrical control component box diagram (). Figure 13 The circuit diagram can be found in the electrical control component box circuit diagram. Figure 14 ).

[0180] The electrical control component box 6 contains a power supply box 64, a PLC controller 63, and a stepper motor driver 62, and is the main electrical control component of the entire hairdressing device system.

[0181] The power supply box 64 contains 24V, 12V, and 5V DC switching power supplies. The 24V power supply provides power to all PLC controllers 63 and stepper motor drivers 62 that use 24V power. The 12V power supply provides power to the stepper motor drivers in the head shape detection device 1 that use 12V power. At the same time, through the step-down circuit in the main circuit board, it provides 10V power to the conductive plastic potentiometer in the head shape detection device 1. The 5V power supply, through the step-down circuit in the main circuit board, provides 3.6V power to the hair clippers in all the hair-cutting control devices 2.

[0182] The PLC control box contains a main circuit board and a PLC controller 63. The PLC controller 63 is used for head shape detection and controlling all steps of the hair clipper's blade movement. The PLC controller 63 also outputs data to the screen of the goggles-type head fixation device (screen glasses-type goggles 52) to display various operational information.

[0183] The stepper motor control box contains the drivers for all the stepper motors in the head shape detection device 1, the hair cutting control device 2, and the earplug-type head fixing device 4.

[0184] The electrical control component of this hairdressing device is the computer control center of the entire device. It plays a crucial role in fixing the head, detecting the user's head shape, storing and processing head shape data, and finally controlling the operation of the hair clippers to complete the entire hairdressing process.

[0185] V. Detailed Explanation of the Structure and Principle of the Head Fixation Device

[0186] In a preferred embodiment of the present invention, the head fixing device includes an earplug-type head fixing device 4 and an eye mask-type head fixing device 5. The earplug-type head fixing device 4 includes an earplug body 41, an earplug support rod 42, a stepper motor lead screw slide 43, a locking rod retainer 44, an earplug pulley assembly 45, and an electronic ruler 46. One end of the earplug support rod 42 is fitted with the earplug body 41, and the other end of the earplug support rod 42 passes through the locking rod retainer 44 and the platform central shaft 3133 in sequence, and is then connected to one end of the earplug pulley assembly 45 by a rope. The other end of the rope passes through the earplug pulley assembly 45 and is connected to the electronic ruler 46. The stepper motor lead screw slide 43 is installed at the bottom of the locking rod retainer 44, and both the stepper motor lead screw slide 43 and the locking rod retainer 44 are wired to the electrical control component box 6.

[0187] In a preferred embodiment of the present invention, an auricle protection ring 47 is provided on one side of the earplug body 41, and a rubber pad is provided inside the auricle protection ring 47. Both the auricle protection ring 47 and the rubber pad inside it are used to protect the user's ear.

[0188] In a preferred embodiment of the present invention, the locking rod retainer 44 includes a locking rod connector 441, a locking rod fixed end 442, and a locking rod movable end 443. The locking rod connector 441 is fitted with the locking rod fixed end 442 and the locking rod movable end 443 at its bottom. Both the locking rod fixed end 442 and the locking rod movable end 443 are fitted with earplug support rods 42. The bottom of the locking rod fixed end 442 is installed to the stepper motor lead screw slide 43. The locking rod movable end 443 is connected to the controller in the electrical control component box 6.

[0189] In a preferred embodiment of the present invention, the movable end 443 of the locking rod includes a left movable member, a right movable member, and an electric suction cup. The left and right movable members are symmetrically arranged, and their tops are both installed to the bottom of the locking rod connector 441. An earplug support rod 42 is provided between the left and right movable members. An electric suction cup is provided on the inner side of the lower end of the left movable member, and the lower ends of the left and right movable members are connected by the electric suction cup. The electric suction cup is electrically connected to the controller in the electrical control component box 6. In actual use, when the electric suction cup is energized, the left and right movable members lock the earplug support rod 42, thereby locking the earplug support rod 42 in the locking rod retainer 44.

[0190] In a preferred embodiment of the present invention, the stepper motor lead screw slide 43 includes an earplug lead screw 431, an earplug slide 432, and an earplug stepper motor 433. The output shaft of the earplug stepper motor 433 is connected to the earplug lead screw 431 via a coupling. The earplug slide 432 is mounted on the nut of the earplug lead screw 431. The earplug slide 432 is mounted above the bottom of the locking rod fixing end 442. The earplug stepper motor 433 is connected to the electrical control component box 6.

[0191] In this embodiment, the structure of the earplug-type head fixation device 4 is shown in the earplug-type head fixation device diagram (). Figure 10 The circuit diagram can be found in the circuit diagram of the earbud-type headrest device. Figure 11 ).

[0192] There are two earplug-type head restraint devices 4, one on the left and one on the right, which are two identical restraints with symmetrical structures. These two restraints are connected to the central axis 3133 of the two platforms of the LU-shaped bracket 313 inside the head cover (which is also the central axis of operation of the two platforms).

[0193] The earplug-type head fixing device 4 includes an earplug body 41, an earplug support rod 42, a stepper motor lead screw slide 43, a locking rod retainer 44, an earplug pulley group 45, and an electronic ruler 46.

[0194] The earplug support rod 42 is fitted into the central hole of the central axis of the LU-type bracket 313. One end of the earplug support rod 42 is connected to the earplug body 41, and the other end of the earplug support rod 42 is connected to the electronic ruler 46 through a connecting wire and the earplug pulley assembly 45.

[0195] The stepper motor lead screw slide 43 is fixed on the LU-shaped bracket 313.

[0196] The locking rod retainer 44 is mounted on the earplug lead screw 431 of the stepper motor lead screw slide 43. The locking rod retainer 44 includes a locking rod controller 441, a locking rod fixed end 442, and a locking rod movable end 443. The earplug support rod 42 in the earplug-type head fixing device can be manually extended and retracted, and can be electronically locked. It can automatically detect whether the head is in the middle position between the two platforms. If it is not in the middle position, it can automatically adjust the position of the head.

[0197] After the user puts on the earplugs and starts the hair-cutting device, the device first activates the locking rod retainer 44, locking the earplug support rod 42 and the locking rod fixing end 442, thus securing the earplug body 41 to the head and keeping it in a fixed position. If the data from the two electronic rulers are inconsistent, it means that the head is not in the center of the head cover. The PLC controller will then output synchronous movement data to the two stepper motor lead screw slides 43, causing the two earplug bodies 41 to move synchronously until the head is in the center of the head cover for haircutting.

[0198] The earbud housings of both earbud bodies 41 are surrounded by an auricular protective ring 47. This auricular protective ring 47 has a ring-shaped spring and an interlocking buckle, which is fixed to the earbud housing. The side of the auricular protective ring 47 that contacts the auricle is covered with rubber. When the user inserts the earbud into the ear canal, the protective ring is fastened and locked, thus protecting the auricle.

[0199] In a preferred embodiment of the present invention, the eye mask type head fixing device 5 includes a forehead fixing end 51, a screen glasses type eye mask 52, an eye mask support rod 53, a support rod bearing 54, and a bearing rod 55. One end of the eye mask support rod 53 is connected to the support rod bearing 54, and the other end of the eye mask support rod 53 is connected to the screen glasses type eye mask 52 through a connecting plate. The forehead fixing end 51 is provided on the top of the screen glasses type eye mask 52. The support rod bearing 54 is installed to the bearing rod 55, and the bearing rod 55 is installed to the U-shaped frame 3131. The screen glasses type eye mask 52 is connected to the electrical control component box 6.

[0200] In this embodiment, the structure of the blindfold-type head fixation device is shown in the blindfold-type head fixation device diagram (). Figure 12 ).

[0201] The blindfold-type head restraint device 5 includes a forehead fixing end 51, a screen glasses-type blindfold 52, a blindfold support rod 53, and a rotatable support rod bearing 54.

[0202] A rotatable support rod bearing 54 is fixed to a bearing rod 55 at a 30-degree angle. When not in use, the eye mask-type head fixing device 5 slides down below the head mask body 311. When in use, it is raised so that the forehead fixing end 51 is at the forehead and fixed (there is a buckle on the support rod bearing 54), thereby fixing the head from the front of the head shape. The screen glasses-type eye mask 52 is used to protect the user's eyes.

[0203] In actual use, the blindfold-type head fixing device 5 is equipped with a screen controlled by a PLC controller 63, which displays information that requires user operation, such as: Please put on the earplugs and lock the ear protection ring buckle, please lift the blindfold-type head fixing device 5 and lock it, please press the start switch, please push open the blindfold-type head fixing device 5, please unlock the ear protection ring buckle and push open the earplugs, please get up and leave the hairdressing device, etc.

In a preferred embodiment of the present invention, the detection component 12 includes a detection head 121 and a detection probe 122. The detection probe 122 includes a probe support rod 1221 and a probe head 1222. The bottom of the detection head 121 is mounted on the detection circuit platform 11. The probe support rod 1221 is installed inside the detection head 121. The other end of the probe support rod 1221 extends out of the detection head 121 and is used to mount the detection probe 122. The detection head 121 is connected to the PLC controller 63 through the detection circuit main board circuit.

[0207] In a preferred embodiment of the present invention, the detection head 121 includes a detection head housing and its interior, a spindle body 1211, a base motherboard 1212, a conductive plastic potentiometer 1213, a detection stepper motor 1214, an electronic clutch 1215, a potentiometer gear set 1216, a clutch gear set 1217, a probe limit micro switch 1218, and a spindle limiting torsion spring. The spindle body 1211 is mounted on the base motherboard 1212 via bearings. The middle part of the spindle body 1211 is connected to the probe support rod 1221 via the spindle limiting torsion spring. An electronic clutch 1215 is installed at one end of the spindle body 1211. The electronic clutch 1215 is connected to the probe support rod 1221 via a bearing. The clutch gear set 1217 is meshed with the gear of the detection stepper motor 1214. The other end of the spindle body 1211 passes through the base motherboard 1212 and is equipped with a spindle gear. The spindle gear is meshed with the potentiometer gear set 1216. The potentiometer gear set 1216 is meshed with the gear of the conductive plastic potentiometer 1213. The conductive plastic potentiometer 1213, the detection stepper motor 1214, the electronic clutch 1215, and the probe limit micro switch 1218 are all installed on the base motherboard 1212. The conductive plastic potentiometer 1213, the electronic clutch 1215, and the probe limit micro switch 1218 are electrically connected to the PLC controller 63.

[0208] In a preferred embodiment of the present invention, the detection platform drive mechanism includes a detection platform drive motor C and a detection platform drive gear set B. The detection platform drive motor C is mounted on one side of the L bracket 3132. The output shaft of the detection platform drive motor C is connected to the platform central shaft 3133 through the detection platform drive gear set B. The control circuit of the detection platform drive motor C is connected to the PLC controller 63.

[0209] In this embodiment, the structure of the head shape detection device 1 is shown in the detection platform diagram. Figure 1 ), Detection header image ( Figure 2 The circuit diagram is shown in the circuit diagram of the head shape detection device. Figure 3 ).

[0210] The detection platform 11 is a semi-circular, semi-annular aluminum plate platform on which several detection heads 121 are mounted. The number of detection heads 121 can be 5, 7, or 9, and is always an odd number, depending on the detection accuracy.

[0211] The detection head 121 is installed in the center of the detection platform 11, such as... Figure 1 As shown, the detection probe 122 extending from the detection head 121 points to the center point of the circle on the detection platform 11.

[0212] The semi-circular bottom edges at both ends of the detection platform 11 are mounted on the platform central axis 3133 of the LU-shaped bracket 313. Driven by its driving stepper motor and gear set, the detection platform 11 rotates around the platform central axis 3133, while simultaneously driving all the detection probes 122 to rotate.

[0213] (II) Working principle of head shape detection device 1:

[0214] With the barber's head fixed in the center of the detection platform 11 (i.e., the barber is in position), the PLC controller 63 initiates head shape detection. During detection, the detection probe 122 begins to contact the bottom of the barber's head from different angles. As the detection platform 11 begins to rotate around the central axis 3133, the detection probe 122, under the action of the main shaft limiting torsion spring, will undulate with the change in the contact position with the head. When the detection probe 122 undulates (specifically, the undulating motion of the detection probe 122 drives the main shaft body 1211 to rotate slightly, the main shaft body 1211 rotates slightly, the main shaft gear rotates, the main shaft gear rotates and meshes with the potentiometer gear set 1216, thereby driving the gear of the conductive plastic potentiometer 1213 to rotate, and the gear of the conductive plastic potentiometer 1213 rotates, thereby causing the conductive plastic potentiometer 1213 to output a level signal to the PLC controller 63), a continuous level signal for head shape detection is sent to the PLC controller 63. Several detection heads 121 detect the head of the barber from different angles, and the head shape detection level signals from different angles are continuously sent to the input terminal of the PLC controller 63. These data are decomposed into hundreds of data in the PLC controller 63 and stored in hundreds of memories, thus completing the storage of head shape data.

[0215] Example 1

[0216] The head shape detection device 1, together with the LU-shaped bracket 313 and the PLC controller 63, constitutes a complete head shape detection device.

[0217] The head shape detection device 1 of this application employs a mechanical probe-based head shape retrieval method, which is a point-by-point scanning technique. This is a very practical technique and also the method that best reduces errors. Point-by-point scanning technique: on each scanning path, there is at least one scanning point every 1 millimeter. Therefore, this technique is a new technology with higher practical application effectiveness compared to other methods. Moreover, this application has undergone multiple tests to verify that point-by-point scanning technology is indeed a new technology that is easy to implement.

[0218] 1. Functions of the head shape detection device components:

[0219] 1) LU type bracket 313:

[0220] The LU-type bracket 313 is the main support frame of the hair-cutting device's head cover, and also a shared support bracket for the head shape detection device 1 and the hair-cutting control device 2. Its structure is shown in the LU-type bracket diagram.

[0221] The two upper ends of the U-shaped bracket 3131 of the LU-type bracket 313 are the main shaft and main bearing of the fixed detection platform 11, as well as the gear set connected to the main shaft to drive the main shaft to rotate and the stepper motor to control the rotation of the main shaft.

[0222] 2) Testing Platform 11:

[0223] (1) Structure of Detection Platform 11:

[0224] The testing platform 11 is a semi-circular, semi-annular aluminum plate platform. Its structure is shown in the testing platform diagram.

[0225] The detection platform 11 is equipped with a detection head 121 and a detection circuit motherboard.

[0226] (2) The number and orientation of the detection heads 121 installed on the detection platform 11:

[0227] The detection platform 11 is equipped with several detection heads 121. The number can be 5, 7, or 9, always an odd number, depending on the detection accuracy. In this embodiment, there are 5 detection heads 121.

[0228] The detection head 121 is installed in the middle of the ring platform, and the detection probe 122 extending from the detection head 121 points to the center point of the ring platform.

[0229] (3) Detection platform drive mechanism:

[0230] The two semi-circular bottom edges of the detection platform 11 are mounted on the platform central shaft 3133 of the LU-shaped bracket 313. The gears on the platform central shaft 3133 and the gears on the detection platform drive motor shaft form a gear set, enabling the detection platform 11 to rotate around the platform central shaft 3133 under the drive of the detection platform drive motor and the gear set. Simultaneously, the detection platform 11 rotates, causing all the detection probes 122 on the platform to rotate around the head along a designated path.

[0231] (4) Original orientation of detection platform 11:

[0232] When the hair-cutting device is not powered on, the head shape detection device 1 is also not powered on. At this time, the detection platform 11 remains in its original position, that is, in the higher original position between the two sides of the L bracket 3132 of the LU-shaped bracket 313. When the hair-cutting device finishes running, the detection platform 11 returns to this original position under the drive of the PLC controller 63.

[0233] 3) Detection head 121:

[0234] (1) Structure of Detection Head 121:

[0235] Although the detection head 121 is small in size, it has many functions and is well-made, which are the main highlights of the invention and innovation.

[0236] Its structural diagram can be found in the outer shape diagram and the main shaft diagram of the detection head. Figure 17 ), Detection head motherboard diagram ( Figure 18 ), Position diagram of the detection head clutch and stepper motor, and position diagram between the detection head potentiometer and the spindle gear ( Figure 19 The circuit diagram is shown in the detection head circuit diagram.

[0237] exist Figure 17 In the diagram, F indicates the location of the electronic clutch 1215, G indicates the location of the spindle limiting torsion spring, H indicates the location of the gear set connecting the spindle body 1211 and the potentiometer, and I indicates the location of the base motherboard 1212.

[0238] The internal structure of the detection head 121 includes a spindle body 1211, a main bearing, a base main board 1212, a conductive plastic potentiometer 1213, a detection stepper motor 1214, an electronic clutch 1215, a spindle limiting torsion spring, a conductive plastic potentiometer shaft limiting torsion spring, a gear set connecting the spindle body 1211 and the potentiometer, a gear set connecting the electronic clutch 1215 fixed on the spindle body 1211 and the detection stepper motor 1214, a detection probe, and a probe limit micro switch 1218.

[0239] (2) Main functions of detection head 121:

[0240] The detection probe 122 on the detection head 121 makes irregular movements by contacting the head, which causes the detection head to output different continuous level signals. This signal is processed by the PLC controller 63 to form the user's head shape data.

[0241] (3) The relationship between the components within the detection head 121:

[0242] a. The spindle body 1211 is a round bar with a diameter of about 8 mm, and the diameter is reduced to 6 mm at one end by about 2 cm. The spindle body 1211 is equipped with (from left to right) an electronic clutch 1215, a detection probe 122, a detection probe torsion spring, a base main board 1212, a main bearing, and a gear between the spindle body 1211 and the sensor (conductive plastic potentiometer 1213).

[0243] b. The detection probe 122 consists of a support rod about 20-30 cm long and a steel ball about 6-8 mm in diameter. The steel ball part points to and contacts the user's head, and the tail of the support rod is directly inserted into the middle part of the main spindle body 1211, perpendicular to the main spindle body 1211, and physically connected to the main spindle body 1211.

[0244] c. The base motherboard 1212 is connected to the spindle body 1211 by the main bearing. The base motherboard 1212 is also equipped with a detection stepper motor 1214, a conductive plastic potentiometer 1213, and a probe limit micro switch 1218.

[0245] d. The detection stepper motor 1214 is installed on the base motherboard 1212 near the electronic clutch 1215 and the detection probe 122, and is connected to the electronic clutch 1215 through a gear set.

[0246] e. The rotary knob of the conductive plastic potentiometer 1213 is installed on the opposite side of the main board and the detection stepper motor 1214, and is connected to the main spindle body 1211 through a gear set between the main board and the main spindle body 1211.

[0247] f. The probe limit micro switch 1218 is installed on one side of the detection probe 122 on the base motherboard 1212. When the detection probe 122 runs to the bottom, it triggers the probe limit micro switch 1218.

[0248] (4) Operating principle of detection head 121:

[0249] When the detection head 121 is not powered on, the probe connected to the spindle body 1211 is pressed tightly against the probe blocking post (the detection probe 122 moves within the annular gap of the detection head housing, and the probe blocking post is located on one side of the annular gap of the detection head housing) under the action of the limiting torsion spring between the probe and the spindle body 1211.

[0250] When the electronic clutch 1215 inside the detection head 121 is energized, the spindle body 1211 is connected to the detection stepper motor 1214 through the electronic clutch 1215 and the gear set between the electronic clutch 1215 and the detection stepper motor 1214. If the detection stepper motor 1214 runs, the spindle body 1211 will run synchronously, and at the same time drive the probe to run synchronously.

[0251] When the detection probe 122 is driven by the detection stepper motor 1214, the probe support rod 1221 contacts the probe limit micro switch 1218. Then the probe limit micro switch 1218 will send a signal to the PLC controller 63 center, causing the control center to send a stop instruction to the detection stepper motor 1214. At this time, the detection probe 122 will also stop running.

[0252] When the electronic clutch 1215 is not energized, the detection probe 122 driven by the spindle body 1211 will rotate directly toward the detection probe 122 blocking post under the action of the limiting torsion spring until it rests against the blocking post.

[0253] During head shape detection, the spherical steel ball end of the detection probe 122 directly contacts the user's head. As the detection platform 11 rotates, the detection probe 122 also moves up and down according to the concave and convex state of the user's head, thereby driving the main shaft body 1211 and the conductive plastic potentiometer 1213 connected to the main shaft body 1211 to rotate.

[0254] The conductive plastic potentiometer 1213 is connected to the spindle body 1211 via a gear set, and rotates synchronously in real time as the spindle body 1211 rotates. However, since the conductive plastic potentiometer 1213 is only energized when needed, it does not output a signal at all times. Instead, it is energized only when signal acquisition head data is required, and outputs a continuous voltage head signal.

[0255] The limiting torsion spring on the conductive plastic potentiometer shaft is designed to compensate for the minute gap between the two gears of the gear set between the main shaft body 1211 and the sensor shaft, so that the detection accuracy of the head-shaped detection device 1 reaches the micrometer level.

[0256] 4) Detection circuit main board:

[0257] The detection circuit main board is mounted on the detection platform 11 and serves as a relay station connecting the electrical circuitry on the platform 11 to the PLC controller 63 in the electrical control component box 6. All the wiring from the electronic clutches, detection stepper motors, conductive plastic potentiometers, and limit microswitches within each detection head 121 is connected to the detection circuit main board. Since the ground wires for the electronic clutches (each with 2 wires), conductive plastic potentiometers (each with 3 wires), and limit microswitches (each with 2 wires) within the detection heads are shared, these shared wires can be connected in parallel. After parallel connection, the number of wires transmitted from the detection heads to the platform circuit main board can be reduced to 5 (including 1 sensor output wire, 1 sensor power wire, 1 limit microswitch control wire, 1 electronic clutch power wire, and 1 shared ground wire). Adding the 4 wires required for the detection stepper motors within each detection head, the total number of wires connecting the detection heads to the detection circuit main board is 9. The number of lines output from the detection circuit mainboard to the PLC controller is determined by two factors. First, shared lines can be merged. Power lines for the electronic clutches in all detection heads can be merged on the mainboard, as can power lines for all sensors and ground lines. This results in a total of 13 wires output from the mainboard to the PLC controller 63 (excluding stepper motor lines): 1 electronic clutch power line, 1 sensor power line, 1 ground line, 5 sensor output lines (for 5 detection heads), and 5 limit microswitch output lines (for 5 detection heads). Second, considering the 4 wiring lines for the stepper motors in each detection head, there are a total of 20 stepper motor connection lines for 5 detection heads. Therefore, the total number of wires output from the detection circuit mainboard to the PLC controller 63 is 33. Thus, the detection circuit mainboard, by merging and connecting the wiring of all the electrical components of the detection heads separately, outputs dozens of lines to the PLC controller 63 of the main circuit control component, effectively transmitting control and detection signals from each detection head 121 to the PLC controller 63.

[0258] The power supply line for the detection platform drive motor that controls the rotation of the detection platform 121 is a separate line, not connected to the main board of the detection circuit. It is a line that connects directly from the detection platform drive motor to the control terminal of the PLC controller 63 in the electrical control component box.

[0259] 5) The PC computer inside the PLC controller 63 is used for data retrieval and storage:

[0260] The PC computer for data retrieval and storage of the head shape detection device 1 of the hairdressing device is the control system of the PLC controller 6. The software control of the PC computer can be designed according to the functions of the detection platform 11, and can control the functional components of the head shape detection device 1 to realize the point-by-point scanning and data storage functions of the user's head.

[0261] First, when the hair-cutting device is turned on, the PC in the PLC controller 63 sends a command to the detection head 121 to open the detection probe 122. This command is executed using the PLSY or DRVA instruction controlled by the PLC controller 63.

[0262] The second step involves initiating the detection process. The PLC controller 63 uses control instructions to gradually lower the detection probe 122 until it finally contacts the user's head, at which point it is in a free-moving state. This gradual lowering instruction is executed using the PLSY or DRVA instruction within the PLC controller 63's control steps. The instruction to allow the detection probe 122 to move freely is achieved by disengaging the power supply to the electronic clutch 1215 using the PLC controller 63's control steps.

[0263] The third step involves activating the rotation of the detection platform 11 and the detection function of the detection head 121, as well as the function of outputting head shape data. This head shape data is then synchronously stored point-by-point in the memory designated by the PLC controller 63. The instruction to activate the rotation of the detection platform 11 is executed using the PLSY or DRVA instruction in the PLC controller 63 control steps. Activating the detection function of the detection head 121 and the function of outputting head shape data are accomplished by the PLC controller 63 controlling the step to energize the detection head 121 and the conductive plastic potentiometer 1213. The continuous voltage form of the head shape signal is controlled by the PC to achieve point-by-point scanning and data storage.

[0264] 2. Operating principle of head shape detection device 1 (refer to) Figures 21-28 ):

[0265] When the hair-cutting device is not turned on, the detection probe 122 rests on the probe blocking post under the action of its main shaft limiting torsion spring, and the head of the detection probe 122 points directly to the center point of the annular platform.

[0266] When the hair-cutting device is turned on, the detection probe 122 opens under the control of the PLC controller 63 (moving away from the center point of the platform) to provide enough space for the user's head.

[0267] When starting the head shape detection step, the open detection probe 122 first approaches the head from different directions under the control of the closed electronic clutch 1215 and the detection stepper motor 1214. Then the electronic clutch 1215 disengages, the detection probe 122 is completely released, and it is pressed against the head.

[0268] At this time, the detection platform 11 starts to rotate under the drive of the detection platform drive motor, which drives the detection probe 122 to rotate around the head in different directions.

[0269] Throughout the testing process, the detection probe 122 moves up and down according to the different shapes of the user's head, while the detection head 121 outputs the corresponding head shape data level signal.

[0270] The head shape data of the detection head 121 is output in the form of continuously changing voltage. After being transmitted to the PC computer of the PLC controller 63, it is controlled by the PLC controller 63 to use point-by-point scanning and storage technology to store the data in the head shape data memory.

[0271] When the detection probe 122 is completed, it opens again, and the detection head 121 stops outputting signals.

[0272] After the haircutting process is completed, the detection platform 11 returns to its original position under the control of the PLC controller 63. The detection probe 122 is also gradually released again, and finally completely released and rests freely on the probe blocking post.

[0273] VII. Structure and Working Principle of Haircutting Control Device 2 (Refer to the section on structure and operating principle of haircutting control device) Figures 22-34 )

[0274] 1. Structure of the haircut control device 2

[0275] In a preferred embodiment of the present invention, the hairdressing control device 2 includes a hairdressing platform 21, hair clippers 22, clipper drive assembly 23, hairdressing platform drive mechanism, and hairdressing circuit main board. The hairdressing platform 21 is connected to the central shafts 3133 on both sides of the platform via a flange D on the right platform central shaft and a bearing E on the left platform central shaft. The hairdressing circuit main board is installed above the hairdressing platform 21, and a plurality of hair clippers 22 are evenly installed below the hairdressing platform 21. Each hair clipper 22 is connected to a clipper drive assembly 23. The hairdressing platform drive mechanism is installed at the right end of the LU-shaped bracket 313 and is connected to the platform central shaft 3133 via a gear set. The hair clippers 22 are connected to the PLC controller 63 via the hairdressing circuit main board circuit, and the control circuit of the hairdressing platform drive mechanism is connected to the PLC controller 63.

[0276] In a preferred embodiment of the present invention, the hair clipper 22 includes a clipper head 221 and a clipper mounting block 222. The clipper mounting block 222 is mounted on one side of the clipper drive assembly 23, and the clipper head 221 is mounted on one side of the clipper mounting block 222.

[0277] In a preferred embodiment of the present invention, the pusher head 221 has a straight or arc-shaped structure.

[0278] In a preferred embodiment of the present invention, the clipper drive assembly 23 includes a clipper support rod 231, a clipper slide 232, a clipper lead screw 233, and a clipper motor 234. The clipper motor 234 is mounted on one side of the hair-cutting platform 21. The output shaft of the clipper motor 234 is connected to the lead screw of the clipper lead screw 233. The clipper slide 232 is mounted on the nut of the clipper lead screw 233. The clipper slide 232 is mounted on one end of the clipper support rod 231. The other end of the clipper support rod 231 is equipped with a clipper mounting block 222. The clipper motor 234 is connected to a PLC controller 63 via a driver.

[0279] In a preferred embodiment of the present invention, the hairdressing platform drive mechanism includes a hairdressing drive motor and a hairdressing platform drive gear set. The hairdressing drive motor is mounted on one side of the L bracket 3132. The output shaft of the hairdressing drive motor is connected to the platform central shaft 3133 through the hairdressing platform drive gear set. The hairdressing drive motor is connected to the PLC controller 63 through a driver.

[0280] In this embodiment, the structure of the hairdressing control device 2 is shown in the hairdressing platform diagram (). Figure 4 The circuit diagram is shown in the circuit diagram of the hairdressing control device. Figure 5 ).

[0281] Like the testing platform 11, the hair-cutting platform 21 is also a semi-circular, semi-annular aluminum plate platform. On the annular hair-cutting platform 21, several stepper motor lead screw slides with hair clippers 22 are arranged around the user's head. The hair clippers 22 are mounted on the slides of the stepper motor lead screw slides, and the combination of the hair clippers 22 and the stepper motor lead screw slides constitutes an electrically controlled hair clipper.

[0282] To reduce the number of clippers and trimmers, the clippers at the sides and top of the head are straight-blade clippers, while the clippers in between are curved-blade clippers. This layout allows the hair clipper 22 to handle flat-top head shapes well, that is, to cut straight-blade clippers on the sides of the user's head and curved-blade clippers on the back and top of the head.

[0283] The number of electrically controlled hair clippers is determined by the required haircutting precision. Generally, it can be 7 or 9 clippers, and in order to achieve a better head shape, it can be 11 or even more clippers.

[0284] The electric-controlled hair clipper is installed in the center of the circular platform, such as... Figure 4 As shown, the blade of the hair clipper 22 points to the center point of the annular platform.

[0285] The semi-circular bottom edges at both ends of the hair-cutting platform 21 are mounted on the platform central shaft 3133 of the LU-shaped bracket 313. Driven by its driving stepper motor and gear set, the hair-cutting platform 21 rotates around the platform central shaft 3133, while simultaneously driving all the electrically controlled hair clippers to rotate.

[0286] 2. Working principle of haircut control device 2 (refer to) Figures 29-34 ,in Figure 29 This is a diagram showing the operating status of the hairdressing control device; Figure 30 for Figure 29 The first subgraph from the left, Figure 30 This is a three-dimensional schematic diagram of the LU-shaped bracket 313 and the hairdressing platform 21; Figure 31 for Figure 29 The second subgraph from the left, Figure 31 This is a side view of the LU-shaped bracket 313 and the hair-cutting platform 21 before they are turned on. Figure 31 Only the middle hair clipper 22 is shown; Figure 32 for Figure 29 The third subgraph from the left, Figure 32 This is a side view of the LU-shaped bracket 313 and the head of the hairdressing platform 21, in a fixed position. Figure 32 Only the middle hair clipper 22 is shown; Figure 33 for Figure 29 The fourth sub-figure from the left, Figure 33 This is a side view of the LU-shaped bracket 313, the hair clipper platform 21, and the hair clipper 22 in their advanced positions. Figure 33 Only the middle hair clipper 22 is shown; Figure 34 for Figure 29 The fifth sub-image from the left, Figure 34 This is a side view of the LU-shaped bracket 313 and the hair-cutting platform 21, with the hair clippers 22 pushed to the end of the haircut. Figure 34 Only the middle barber clipper 22 is shown:

[0287] When the haircutting control process begins, the PLC controller 63 first receives hundreds of recognizable head shape data from the head shape detection device 1. Following a standard head shape template, this data is converted into haircutting control data that controls the movement of the stepper motor, lead screw, and slide hair clipper head. Based on the control data from the PLC controller 63, the stepper motor, lead screw, and slide hair clipper head 221 first contacts the bottom of the customer's head at different angles. Then, as the haircutting platform 21 begins to rotate around the platform's central axis 3133, it performs corresponding movements according to the control data from the PLC controller 63, causing the clipper head to perform haircutting actions around the customer's head. Because this movement follows the contour of a standard head shape, the resulting haircut is a standard head shape.

[0288] The hair-cutting control device 2, together with the LU-type bracket 313 (shared with the head shape detection device 1) and the hair fragment collection device 7, constitute a hair-cutting control device.

[0289] 3. Functions of the hairdressing control device components:

[0290] 1) LU-type bracket 313 (shared with head shape detection device):

[0291] The LU-type bracket 313 is the main support frame of the hair-cutting device's head cover, and also a shared support bracket for the head shape detection device 1 and the hair-cutting control device. Its structure is shown in the LU-type bracket diagram. Figure 7 ).

[0292] The two upper ends of the U-shaped bracket 3131 of the LU-type bracket 313 are the main shaft and main bearing for fixing the hair-cutting platform 21, as well as the gear set connected to the main shaft to drive the main shaft to rotate and the stepper motor for controlling the rotation of the main shaft. In this way, the hair-cutting platform 21 can rotate along the main shaft under the drive of the stepper motor.

[0293] 2) Hairdressing Platform 21:

[0294] (1) Structure of the hairdressing platform 21:

[0295] The barber platform 21 is a semi-circular, semi-annular aluminum plate platform. Its structure is shown in the barber platform diagram. Figure 4 ).

[0296] The hair-cutting platform 21 is equipped with a stepper motor, lead screw, slide, hair clipper, and hair-cutting circuit main board.

[0297] (2) The number and orientation of the stepper motor lead screw slide and hair clippers installed on the hair clipper platform 21:

[0298] The hair-cutting platform 21 is equipped with several stepper motor lead screw slide hair clippers. The minimum number of clippers is 7, or more, depending on the hair-cutting precision required. In this embodiment, the number of stepper motor lead screw slide hair clippers is set to 7.

[0299] The stepper motor, lead screw, slide table, and hair clipper are installed around the center of the ring platform, with the extended clipper pointing towards the center point of the ring platform.

[0300] (3) Haircutting platform drive mechanism:

[0301] The two semi-circular bottom edges of the hair-cutting platform 21 are mounted on the platform central shaft 3133 of the LU-shaped bracket 313. The gears on the platform central shaft 3133 and the gears on the hair-cutting platform drive stepper motor shaft form a gear set, enabling the hair-cutting platform 21 to rotate around the platform central shaft 3133 under the drive of the hair-cutting drive motor and the gear set. Simultaneously, the hair-cutting platform 21 rotates, causing all the stepper motor lead screws, slides, and hair clippers on the platform to rotate around the head along a designated path.

[0302] (4) Original location of barber platform 21:

[0303] When the hair-cutting process is in the activated state, the hair-cutting platform 21 remains in its original position, specifically the lower original position between the two sides of the L-bracket 3132 of the LU-shaped bracket 313. When the hair-cutting device finishes operating, the hair-cutting platform 21 should be driven back to this original position according to the steps.

[0304] (5) Operation mode of hairdressing platform 21:

[0305] When the haircutting process is started, the stepper motor lead screw slide hair clipper is controlled to move forward and backward according to the data control of PLC controller 63 and the control steps output by clipper drive component 23. At the same time, the haircutting platform 21 also begins to rotate around the head. The two work together to complete the haircutting of the user's head shape.

[0306] 3) Stepper motor, lead screw, slide table, hair clipper:

[0307] The stepper motor lead screw slide hair clipper is composed of a hair clipper 22 and a clipper drive assembly 23. Its structure is shown in the stepper motor lead screw slide hair clipper diagram. Figure 20 ).

[0308] (1) Hair clippers 22:

[0309] This hair-cutting control device uses two types of hair clippers 22: one is a wide-body hair clipper with a straight blade, and the other is a wide-body hair clipper with an arc-shaped blade. The hair clippers 22 are mounted at the end of the clipper drive assembly 23 and move back and forth under the drive of the clipper drive assembly 23. The hair clippers 22 are activated only when the hair-cutting step is started.

[0310] (2) Fader drive component 23:

[0311] The clipper drive assembly 23 is a device capable of moving back and forth instantaneously under the control of the clipper motor 234. When the haircutting process is activated, the stepper motor lead screw slide controls the forward and backward movement of the hair clipper 22 according to the data control and the control steps output by the clipper motor 234, so that the hair clipper 22 can cut the user's head according to the corrected head shape data to create a standard haircut.

[0312] (3) Installation and arrangement of stepper motor lead screw slide for hair clippers:

[0313] The stepper motor, lead screw, and slide table hair clippers are mounted on a semi-circular hair-cutting platform 21, with evenly spaced blades that surround the user's head. The simplest hair clipper layout 22 for a buzz cut uses straight blades on the sides and top of the head, and curved, wide blades on the other sides.

[0314] 4) Hair clipper circuit mainboard:

[0315] This motherboard is installed on the hairdressing platform 21.

[0316] The four stepper motor control lines and two power lines of each stepper motor lead screw slide hair clipper are all converged on the main circuit board. On this main circuit board, the two power lines of all hair clippers are merged into two power lines, which are connected to the PLC controller 63 of the main circuit control component together with the other stepper motor control lines.

[0317] In the most basic configuration using 7 stepper motor lead screw slide hair clippers, there are a total of 30 wires from the main board to the PLC controller 63. Of these, 28 are for the 7 stepper motors (clipper motors 234), and the other 2 are power cables shared by the 7 hair clippers 22. The hair clippers 22 have their own dedicated wiring because they draw a very large current, requiring thicker wires to meet their demands.

[0318] 5) PLC controller 63:

[0319] The PLC controller 63 is an important component of the electrical control assembly of the hair clipper device. Its function is to analyze the head shape data input from the head shape detection device, match it with standard head shape model data, and after processing (all processing is existing technology), output control data to the clipper drive assembly 23. The clipper drive assembly 23 controls the operation of the stepper motor, lead screw, slide table, and hair clipper to complete the hair clipper operation.

[0320] The head shape data input and stored from head shape detection device 1 consists of head shape data from 5 paths, with each path containing 450 data points, stored in 450 memory slots. The 5 paths total 2250 data points.

[0321] A set of standard head shape data, consisting of 450 points, should be stored in the PC of the PLC controller 63 beforehand, serving as the standard model 0 data.

[0322] In the PLC controller 63, the clock pulse serves as the trigger pulse for analyzing and calculating each piece of data, enabling conversion and analysis and calculation operations on each piece of data.

[0323] Triggered by a trigger pulse, the PC within the PLC controller 63 compares each user's original head shape data with a standard model head shape data at the same position, generating a difference data. This difference data is then added to the original data to form basic haircutting control data. After the PC compares each original head shape data with the standard model head shape data, a complete set of haircutting control data is formed. The above processing is existing technology. The PLC controller 63 outputs the haircutting control data to the clipper drive assembly 23. This controls the forward and backward movement of the stepper motor lead screw slide, thereby adjusting and controlling the entry point of each hair clipper point to complete the haircutting operation.

[0324] The basic technical principle of the operation of the hairdressing control device 2:

[0325] Each channel of 450 head shape data points is input from the head shape data storage in the head shape detection device 1. These data points are extracted one by one by the PLC controller 63 when the haircutting process begins. The PLC controller 63's PC computer matches and compares these data with standard head shape model data, processing them to form standard head shape data suitable for the user. This standard head shape data is then output by the PLC controller 63 to the stepper motor lead screw slide hair clipper. The stepper motor lead screw slide in the hair clipper drives the front hair clipper, adjusting the cutting point of each clipper point by point, thus creating the desired haircut for the user's head.

[0326] All electrical devices involved in this application are prior art, and this application does not involve any process improvement.

[0327] Besides its intelligent feature (automatic haircutting), this smart hair-cutting device also boasts two major advantages: speed and standardization. Speed ​​means a short processing time; a typical haircut takes at least 10 minutes, while this device typically completes it in 3-5 minutes. Standardization means the resulting hairstyle is a standard head shape, comparable to that of a master barber. This is because the device is programmed with a standard head shape model (stored in the PLC controller 63's PC) based on the user's head shape data. This model, combined with the user's head shape data, calculates the clipper's operating data, thus providing the user with a standard head shape haircut.

[0328] This patent application is based on relevant principle experiments. Its core technologies are point-by-point scanning and data storage technology used in head shape detection, and data integration and instantaneous blade movement technology used in hairdressing control. Experiments have shown that these technologies have achieved practical technical results. Therefore, they have practical application significance.

[0329] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
