Description

tattoo device

The present invention relates to a tattoo device, and in particular, a method in which a tattoo dye is injected into the correct scalp layer by fully automatically adjusting the draw-out length of a needle for injecting a dye, and the force becomes stronger when the speed of the needle up and down movement in the existing tattoo machine increases By controlling the speed, frequency, and force (torque) of the needle up and down individually, it is possible to take a more controlled and precise dot. It relates to a tattoo device that can prevent the spread of hair.

Scalp tattooing refers to a procedure that injects pigment by making fine dots on areas where hair is lacking or has disappeared. There is an advantage in that the visual effect like hair transplantation is emphasized, and the procedure time and cost can be reduced at the same time.

When tattooing with black pigment, the black pigment turns blue over time and then green over time. In order to minimize such discoloration, it is very important to control the depth of the needle for injecting the pigment, the amount of the pigment, and evenly injecting the pigment into the correct upper dermis layer of the scalp without damaging the hair follicles.

In particular, when making dots on the scalp using pigments, it is important to make dots at regular intervals and depths. Here, if a certain interval, a depth, and a time difference for making a dot are different, the size of the dot is changed or the color is changed only in a specific area. This occurs when the movement time of the hand is different or the pressure applied to the scalp is different when the operator uses his hand to tattoo the scalp.

Therefore, in recent years, various scalp tattooing equipment and methods have been proposed to improve these problems and to allow the tattoo to be made evenly on an accurate scalp layer.

Using such a tattoo device, a natural hair style is realized by injecting pigment like a dot to the area where hair is lacking or disappeared.

The setting unit 10 is a part where the user (operator) sets the needle withdrawal length, withdrawal speed, and dye injection amount. The needle withdrawal length is preferably set by an expert who is an expert in the condition of the skin.

The needle unit 20 is a needle for injecting a tattoo dye into the scalp, and is mounted inside a probe that contacts the scalp.

The movement speed sensing unit 50 serves to detect the movement speed of the tattoo device in the form of a handpiece. An acceleration sensor or the like may be used to detect moving speed.

The pressure sensing unit 40 serves to sense the pressure between the scalp and the probe, and may be installed at the end of the probe and may use a pressure sensor.

The display unit 70 displays the setting value set by the operator, and serves to display information such as the tattoo time, and the memory 80 stores information such as the needle withdrawal speed, length, and amount of dye injection set by the operator, and , it serves to store control values for needle withdrawal speed and length control and dye injection amount control values.

The power supply unit 90 is a part that supplies driving power to the tattoo device, and may use a built-in battery or use an external commercial AC power source. When using an external commercial AC power source, the built-in battery can be charged by using the built-in battery as a secondary battery.

The tattoo control unit 60 controls the main operation of the scalp tattoo apparatus based on the needle withdrawal length, withdrawal speed, and pigment injection amount set by the setting unit 10, but referring to the movement speed and pressure sensing value, and withdrawing speed and force It serves to additionally control the operation of the tattoo device by individually controlling the

As shown in FIG. 2, the tattoo control unit 60 includes a needle withdrawal speed setting unit 61, the setting unit ( Needle withdrawal length setting unit 62 for setting the needle withdrawal length based on the needle withdrawal length set by 10), dye injection amount setting for setting the dye injection amount based on the dye injection amount set by the setting unit 10 Unit 63, a movement speed determination unit 65 that determines the movement speed of the tattoo device based on the movement speed value sensed by the movement speed detection unit 50, and the pressure detection unit 40 detects pressure The pressure determination unit 64 that determines the pressure between the scalp and the probe by the value, controls the needle driving speed according to the set needle withdrawal speed, and the needle speed that controls the on/off operation of the scalp tattoo device with the sensed needle movement speed The control unit 66, the needle withdrawal length control unit 68 that variably controls the needle withdrawal length in real time according to the set needle withdrawal length and the pressure sensing value, and controls the needle torque according to the set amount of dye injection to prevent dye bleeding and a needle torque control unit 67 .

The needle driving unit 30 serves to control the needle driving of the needle unit 20 mounted on the probe according to the control of the tattoo control unit 60 . The needle driving unit 30 includes a needle driving motor and a solenoid, and precisely controls the needle withdrawal length and withdrawal speed by using the solenoid.

The operation of the tattoo device according to the present invention configured as described above will be described in detail as follows.

First, the operator supplies power through the power supply unit 90 in order to use the tattoo device. When driving power is supplied by the power supply unit 90 , the tattoo control unit 60 initializes and waits for input values set by the setting unit 10 . Here, if the user operates through the input unit without separately setting the needle withdrawal speed, length, color injection amount, etc., the tattoo control unit 60 stores information such as the needle withdrawal speed, withdrawal length, and pigment injection amount stored in the memory 80 . It controls the operation of the tattoo device by drawing it out.

Contrary to this, when the operator sets the needle withdrawal length, withdrawal speed, and dye injection amount through the setting unit 10, the operation of the tattoo device is controlled based on this. Here, the user (operator) sets the needle withdrawal length and pigment injection amount by looking at the scalp condition of the subject to be treated. The scalp condition of the human body may be different. Some may be hard, others may be relatively soft. The tattoo is closely related to the depth of the needle and the amount of pigment. In particular, it is necessary to accurately inject the pigment into the thin layer of the scalp to prevent discoloration or staining, and to create a natural hairstyle. Therefore, it is very important to check the condition of the scalp of the subject to be treated to determine the needle withdrawal length and the amount of pigment injection. Therefore, it is desirable to perform the procedure by an expert (operator) with a lot of experience and know-how.

It is desirable to set the needle withdrawal speed by an expert based on the condition of the scalp, that is, long hair, bald hair, etc.

When the operator sets the needle withdrawal length, speed, and pigment injection amount through the setting unit 10 , the tattoo control unit 60 controls the operation of the tattoo device based on this.

That is, the tattoo control unit 60 extracts a control value from the memory 80 based on the needle withdrawal length, withdrawal speed, and pigment injection amount set by the setting unit 10 to control the main operation of the scalp tattoo device, but move The motion of the tattoo device is additionally controlled by referencing the speed and pressure sensing values and individually controlling the withdrawal speed and force.

For example, the needle withdrawal speed setting unit 61 of the tattoo control unit 60 extracts the needle withdrawal speed control value from the memory 80 based on the needle withdrawal speed set by the setting unit 10 to determine the needle withdrawal speed. set

In addition, the needle withdrawal length setting unit 62 sets the needle withdrawal length by extracting the needle withdrawal length control value from the memory 80 based on the needle withdrawal length set by the setting unit 10 .

Also, the dye injection amount setting unit 63 sets the dye injection amount by extracting a dye injection amount control value from the memory 80 based on the dye injection amount set by the setting unit 10 .

The needle drive control unit 66 drives the motor and the solenoid of the needle drive unit 30 according to the set needle withdrawal speed, the needle withdrawal length, and the dye injection amount to control the needle withdrawal length and withdrawal speed of the needle unit 20 while controlling the scalp Control your tattoos.

When the scalp tattoo starts, the movement speed sensing unit 50 detects the movement speed value of the handpiece using an acceleration sensor, etc. is used to measure the pressure between the scalp and the probe and transmit it to the tattoo control unit 60 in real time.

The movement speed determination unit 65 of the tattoo control unit 60 compares the movement speed value detected by the movement speed detection unit 50 with the reference movement speed range value registered in the memory 80, and moves when an abnormality occurs. A speed determination value is generated and transmitted to the needle speed control unit 66 . That is, when the movement speed value sensed by the movement speed sensor 50 exceeds or falls short of the reference movement speed range, a movement speed determination value is generated and transmitted to the needle speed control unit 66 . Here, if the moving speed of the handpiece is too fast or too slow, it is impossible to achieve a uniform and natural hairstyle. For example, if the moving speed is too fast, the amount of pigment injected is small and the hair is not implemented properly, so the effect of a scalp tattoo is small. there is. Therefore, it is preferable to tattoo the scalp while moving the handpiece within a predetermined moving speed range.

When the movement speed determination value is transmitted from the movement speed determination unit 65, the needle speed control unit 66 recognizes this as a stop interrupt and automatically stops the operation of the scalp tattoo device. That is, the needle driving unit 30 is stopped. It is also preferable to display a warning message through the display unit 70 if necessary. When the tattoo device suddenly stops during scalp tattooing, the operator checks a warning message through the display unit 70 and recognizes that the moving speed of the handpiece is too slow or too fast. After that, the tattoo device is operated again and the scalp is tattooed while paying attention to the speed of movement.

In addition, the pressure determination unit 64 of the tattoo control unit 60 compares the pressure value sensed by the pressure detection unit 40 with the reference pressure range value registered in the memory 80, and when an abnormality occurs, the pressure determination value is generated and transmitted to the needle withdrawal length control unit 68.

That is, when the pressure value sensed by the pressure sensing unit 40 exceeds or falls short of the reference pressure range value, a pressure determination value is generated and transmitted to the needle withdrawal length control unit 68 . Here, if the pressure between the probe and the scalp is too high or too low, it is difficult to inject the pigment into the correct scalp layer (thin layer), making it impossible to implement a uniform and natural hairstyle. For example, if the pressure value is too high, the pigment is injected into an unwanted deep layer, and if the pressure value is too low, the pigment is injected only on the unwanted surface of the scalp, causing a disadvantage in that hair is not implemented properly. Therefore, it is desirable to tattoo the scalp within a certain pressure range.

In addition, when the movement speed determination value is transmitted from the movement speed determination unit 65, the needle withdrawal length control unit 68 automatically controls the needle withdrawal length based on this. That is, if the pressure value is higher than the predetermined range, the withdrawal length adjustment value is fetched from the memory 80, and the solenoid of the needle driving unit 30 is controlled to relatively shorten the withdrawal length of the needle, and when the pressure value is lower than the predetermined range, the memory The solenoid of the needle driving unit 30 is controlled so that the withdrawal length adjustment value is extracted from the 80 and the withdrawal length of the needle is relatively long.

On the other hand, as another feature of the present invention, the speed of the needle (when the up and down movement is considered as one cycle, it means cycle/sec, once or 10 times per second, etc.) and force (torque) are individually controlled. Through this, by controlling the number of needle penetrations per second (improving the operator's control ability) and the needle force (necessary for shaking and resistance of the skin when the needle penetrates), the needle penetrates the target skin layer more stably without skin pushing. it will be possible to do In general motor-type tattoo equipment, if the vertical movement of the needle is slow, the skin is pressed by the needle, making it difficult to selectively penetrate the needle into the lower layer.

That is, the present invention controls the needle driving speed and torque (force) individually, so that even when the speed is slow, the instantaneous force, the torque, can be increased to inject the pigment into the highest surface of the skin, so that it spreads compared to the deeply injected pigment. prevent.

In other words, the needle speed control unit 66 controls the needle driving speed according to the set needle withdrawal speed, and controls the on/off operation of the tattoo device by the sensed needle movement speed.

In addition, the needle withdrawal length control unit 68 controls the needle withdrawal length, which variably controls the needle withdrawal length in real time according to the set needle withdrawal length and the pressure sensing value.

In the state in which the needle movement speed and the withdrawal length are adjusted in the above manner, the needle torque control unit 67 controls the needle torque according to the set amount of dye to be injected to prevent the dye from spreading. The needle torque control unit 67 may operate in conjunction with the needle speed control unit 66 .

Here, the torque is an instantaneous force, and by individually controlling the needle speed differently, the injected pigment on the surface of the skin is prevented from spreading. Here, the force is the force that penetrates the skin. In general, the higher the needle speed, the stronger the force, and the lower the needle speed, the weaker the force is. Since it is a characteristic of general tattoo equipment that uses a motor, the power to penetrate the scalp at a low speed is also lowered, so that the There is a disadvantage that the pigment is injected and spread on the surface of the scalp because the insertion is not performed.

The present invention uses a solenoid to improve the disadvantages of such general tattoo equipment, and by individually controlling the needle speed and the torque that is the force that penetrates the skin, the torque is increased even in a low needle speed situation so that the pigment is always supplied at an appropriate depth of the scalp By injecting it, it is possible to prevent the pigment from spreading.

Similarly, in a situation where the needle speed is high, the torque is appropriately lowered so that the pigment is always injected at an appropriate depth of the scalp, thereby preventing the pigment from spreading.

Here, the needle driving unit 30 serves to adjust the needle withdrawal speed, length, and torque of the needle unit 20 mounted on the probe under the control of the tattoo control unit 60 . It includes a driving motor and a solenoid, and precisely controls the needle withdrawal length, withdrawal speed, and torque by using the solenoid.

In addition, the tattoo control unit 60 controls the pigment supply unit 100 according to the color injection amount set by the operator to precisely control the pigment injection amount. The dye injection amount can be precisely controlled by varying the nozzle opening size or intensity.

As such, when the scalp tattoo starts, the movement speed and the pressure between the scalp and the probe are sensed in real time, and the needle withdrawal length is variably controlled in real time according to the sensed pressure value, thereby realizing the optimal scalp tattoo.
