Description

UV cleaning device controlling the amount of UV irradiation based on the surface area of the cleaning material {Apparatus for UV cleaning and controlling amount of UV based area of the cleaning material}

The present invention relates to a cleaning device to which transfer automation is applied, and more particularly, to perform cleaning by irradiating ultraviolet rays to an object to be cleaned passing through a cleaning area formed inside a chamber, passing through a carrying-in area, a cleaning area, and a carrying-out area in turn. The present invention relates to a cleaning apparatus to which an object to be cleaned passes through a cleaning area by opening and closing an opening and closing unit when an object to be cleaned approaches a cleaning area and when an object to be cleaned approaches a carrying area.

In recent years, as interest in personal hygiene has increased, research and development on ultraviolet (UV) sterilizers have been actively conducted. Personal belongings related to personal hygiene management include mobile phones, toys, portable medical devices, etc. Among them, mobile phones are not only the most frequently contacted objects throughout the day, but also require sterilization due to their high degree of contamination. Furthermore, in the case of mobile phones, it is necessary to periodically sterilize them in consideration of bacterial growth and infection.

As a personal belongings sterilizer according to the prior art, a storage-type ultraviolet sterilizer emitting ultraviolet rays using a mercury lamp is widely used. Such a conventional ultraviolet sterilizer is to sterilize items in a box-type storage box by using ultraviolet rays emitted from a mercury lamp, which is a light source.

In addition, other conventional ultraviolet sterilizers have weak sterilizing power and are inefficient, such as requiring sterilization for a long time, for example, several tens of minutes to several hours.

Other conventional UV sterilizers require a warm-up time of 10 minutes to 1 hour to obtain a certain amount of light energy, so it is difficult to immediately sterilize the conveyed material loaded on the conveyor.

Recently, LED (Light Emitting Diode), LD (Laser Diode), etc. have been developed and attracted attention as an alternative light source for mercury lamps. In particular, the LED light source is small in size, can be used without warm-up time by selecting only a desired wavelength band, has a lifespan of tens of thousands of hours, and is environmentally friendly.

However, there is a disadvantage in that the price of LED emitting light in the ultraviolet band (250 ~ 280 nm) with excellent sterilization power is high. For example, the price of an LED that emits ultraviolet rays in the 405nm band is considerably cheaper than that of a light source that emits ultraviolet rays in the 250-280nm (UV-C) band, but its sterilization power is about 1,000 times weaker, so it is mainly used to sterilize items that can be sterilized for a long time. It is used as a light source for a sterilizer.

As such, the ultraviolet sterilizer using the LED light source according to the prior art has to emit ultraviolet rays for several minutes to several hours due to insufficient light intensity, and uniform sterilization is difficult, so it is applied to a storage type sterilizer. In the case of a conventional ultraviolet sterilizer that uses an LED light source and is applied to a conveyor, it is implemented in a way that emits ultraviolet rays directly to the object to be sterilized without going through an optical system, so there is a problem in that sterilization efficiency decreases and ultraviolet rays harmful to the human body leak out.

The chamber 120 is disposed between the carrying-in area AR1 and the carrying-out area AR3 in the transport path, is formed as a partition wall to configure the cleaning area AR2 therein, and has an entrance opening toward the carrying-in area AR1 and An outlet opening toward the discharge area AR3 may be provided.

The chamber 120 may include a chamber body 121 having a quadrangular frame shape with an open top, bottom, inlet, and outlet, and a chamber lid 122 configured to open and close the top of the chamber body 121 .

That is, as the chamber cover 122 closes the upper portion of the chamber body 121 , a cleaning area AR2 , which is a predetermined space, may be formed inside the chamber 120 .

The cleaning unit 140 may be disposed on the lower surface of the chamber cover 122 .

The cleaning unit 140 will be described later.

The opening/closing unit 130 may include a first door unit 131 that opens and closes an inlet of the chamber 120 and a second door unit 132 that opens and closes an outlet of the chamber 120 .

The cleaning unit 140 is disposed inside the chamber 120 and may irradiate ultraviolet rays to the cleaning area AR2 in the transfer path.

Specifically, the cleaning unit 140 may be disposed on the lower surface of the chamber cover 122 of the chamber 120, and irradiates the object P included in the cleaning area AR2 with ultraviolet rays to the object to be cleaned. (P) can be washed.

Here, the ultraviolet light may be a first ultraviolet light having a wavelength of 184.9 nm and a second ultraviolet light having a wavelength of 253.7 nm.

More specifically, the cleaning unit 140 irradiates first ultraviolet rays to dissociate oxygen (O2) included in the cleaning area AR2, thereby photo-decomposing into oxygen radicals (O) and ozone (O3).

Thereafter, the cleaning unit 140 may irradiate the second ultraviolet rays to photodecompose the ozone (O3) included in the cleaning area (AR2) into oxygen radicals (O). Expressing this as a reaction formula, it is as follows.

[Scheme 1] O2　+ UV (184.9nm) → O3, O

[Scheme 2] O3　+ UV (253.7nm) → O

In this way, the photodecomposed oxygen radicals (O) oxidize and decompose the contaminants present on the surface of the object to be cleaned (P) in the cleaning area (AR2).

That is, oxygen radicals (O) sever the C-C bonding of pollutants, and then combine with C to produce carbon monoxide (CO) or carbon dioxide (CO2).

Then, the oxygen radical (O) cleaves the C-H bond of the contaminant and then combines with H to produce water (H2O).

Here, the temperature of the cleaning area AR2 should be at least 30° C. or higher, and the higher the temperature is maintained, the better the effect. Preferably, the temperature of the cleaning area AR2 may be between 30 degrees Celsius and 120 degrees Celsius.

In order to perform the aforementioned role, the cleaning unit 140 may include a plurality of UV lamps 141 radiating first and second ultraviolet rays to the cleaning area AR2 . In addition, the cleaning unit 140 may include a lamp plate 142 in which a plurality of UV lamps 141 are installed.

That is, the lamp plate 142 is disposed inside the chamber cover 122, and a plurality of UV lamps 141 may be installed in the lamp plate 142.

Meanwhile, the cleaning unit 140 may include a piston 143 that controls the separation distance between the cleaning unit 140 and the object P to be cleaned by raising or lowering the lamp plate 142 .

The length of the piston 143 is increased to lower the lamp plate 142, thereby shortening the separation distance between the cleaning part 140 and the object to be cleaned P, and the length of the piston 143 is reduced to raise the lamp plate 142, A separation distance between the cleaning unit 140 and the object to be cleaned P may be increased.

Since the cleaning unit 140 is controlled by the processor 160, the light intensity of ultraviolet light and the separation distance between the cleaning unit 140 and the object to be cleaned P may be controlled.

The sensing unit 150 determines whether an object to be cleaned P exists in each of the carrying-in area AR1, the entrance area AR1', the cleaning area AR2, the exit area AR3', and the carrying-out area AR3. and whether the object to be cleaned (P) enters each of the carrying-in area (AR1), the entrance area (AR1'), the cleaning area (AR2), the exit area (AR3'), and the carrying-out area (AR3). there is.

Also, the sensing unit 150 may sense the surface area of the object to be cleaned P included in the cleaning area AR2.

Also, the sensing unit 150 may sense the thickness of the object to be cleaned P included in the cleaning area AR2.

Also, the sensing unit 150 may sense a separation distance between the cleaning unit 140 included in the cleaning area AR2 and the object P to be cleaned.

To this end, the sensing unit 150 may include one or more of an infrared sensor, a depth camera module, and an ultrasonic sensor.

The processor 160 controls the transport unit 110, the opening/closing unit 130, and the cleaning unit ( 140) can be controlled.

Specifically, as shown in FIG. 4 , the processor 160 detects the object P to be cleaned in the entrance area AR1' adjacent to the cleaning area AR2 in the carrying area AR1, the first door unit. The opening/closing unit 130 may be controlled so that the opening 131 is opened.

Conversely, as shown in FIG. 5 , the processor 160 controls the opening/closing unit 130 to close the first door unit 131 when the object P to be cleaned is not detected in the entrance area AR1′. can

Then, when the object P to be cleaned is detected in the cleaning area AR2, the processor 160 may control the cleaning unit 140 to emit ultraviolet rays.

More specifically, when the object P to be cleaned is detected in the cleaning area AR2, the processor 160 acquires surface area information of the object P facing the cleaning unit 140, and obtains the surface area information. Based on this, it is possible to calculate target ultraviolet radiation amount information corresponding to the object to be cleaned P.

At this time, the processor 160 may set the target ultraviolet radiation amount information as the target ultraviolet radiation amount indicated by the target ultraviolet radiation amount information increases as the surface area indicated by the surface area information increases.

That is, the processor 160 may calculate target ultraviolet radiation amount information using a target ultraviolet radiation amount per unit surface area. Specifically, the processor 160 may calculate the target ultraviolet radiation amount information by applying the target ultraviolet radiation amount per unit surface area to the surface area indicated by the surface area information.

Meanwhile, according to another embodiment, the processor 160 may check the target ultraviolet radiation amount corresponding to the information on the surface area of the object P by referring to reference data to which the target ultraviolet radiation amount for each surface area is mapped.

The processor 160 may set the target ultraviolet radiation amount identified through the reference data as the above-described target ultraviolet radiation amount information.

Thereafter, the processor 160 controls the cleaning unit so that the irradiation amount of ultraviolet rays irradiated to the object P to be cleaned reaches the target amount of ultraviolet rays indicated by the target amount of ultraviolet rays irradiation information while the object P to be cleaned passes through the cleaning area AR2. At least one of a separation distance between the object 140 and the object P to be cleaned, the light intensity of ultraviolet rays irradiated from the cleaning unit 140, and a transport speed of the object P to be cleaned may be controlled.

The processor 160 may control the cleaning unit 140 so that the separation distance between the cleaning unit 140 and the object P to be cleaned becomes shorter as the target ultraviolet irradiation amount indicated by the target ultraviolet irradiation amount information increases.

In addition, the processor 160 may control the cleaning unit 140 so that the light intensity of ultraviolet light emitted from the cleaning unit 140 increases as the target ultraviolet radiation amount indicated by the target ultraviolet radiation amount information increases.

In addition, the processor 160 may control the transfer unit 110 so that the transfer speed of the object P to be cleaned becomes slower as the target ultraviolet irradiation amount indicated by the target ultraviolet irradiation amount information increases.

Specifically, when the object to be cleaned (P) enters the cleaning area (AR2), the processor 160 controls the transfer speed of the current object (P) and the cleaning unit (140) so that the object (P) and the object (P) are cleaned. While the object to be cleaned (P) passes through the cleaning area (AR2) based on the minimum separation distance that the cleaning unit 140 can maintain at a minimum and the light intensity of ultraviolet rays irradiated from the cleaning unit 140, the object to be cleaned ( It is possible to calculate the predicted UV irradiation amount of UV rays to be irradiated to P).

For example, the processor 160 may perform a situation in which the predicted ultraviolet radiation amount is smaller than the target ultraviolet radiation amount, the conveying speed of the object P to be cleaned is reduced, and the light intensity of the ultraviolet light emitted from the cleaning unit 140 is increased. Assuming that, the predicted UV dose can be calculated.

The processor 160 predicts the prediction by assuming a situation in which the transfer speed of the object P to be cleaned is reduced and the light intensity of the ultraviolet light irradiated from the cleaning unit 140 is increased when the predicted ultraviolet radiation amount is smaller than the target ultraviolet radiation amount. The amount of UV irradiation can be calculated.

The processor 160 controls the transfer unit 110 and the cleaning unit 140 so that the transfer speed of the object P and the light intensity of ultraviolet rays are maintained in the hypothesized situation when the predicted ultraviolet irradiation amount is equal to the target ultraviolet irradiation amount. can do.

For another example, the processor 160 may perform a situation in which the transfer speed of the object P to be cleaned is increased and the light intensity of the ultraviolet light irradiated from the cleaning unit 140 is reduced when the predicted ultraviolet radiation amount is greater than the target ultraviolet radiation amount. Assuming the situation, the predicted ultraviolet irradiation amount can be calculated.

The processor 160 controls the transfer unit 110 and the cleaning unit 140 so that the transfer speed of the object P and the light intensity of ultraviolet rays are maintained in the hypothesized situation when the predicted ultraviolet irradiation amount is equal to the target ultraviolet irradiation amount. can do.

Meanwhile, as shown in FIG. 6 , the processor 160 detects an object P to be cleaned in the exit area AR3' adjacent to the carrying out area AR3 in the cleaning area AR2, the second door unit ( The opening/closing unit 130 may be controlled so that the opening 132 is opened. Conversely, as shown in FIG. 7 , the processor 160 controls the opening/closing unit 130 to open the second door unit 132 when the object to be cleaned P is not detected in the exit area AR3′. can

Through this, the processor 160 minimizes the leakage of ultraviolet rays, ozone, and other harmful gases into the chamber 120, and at the same time, the transfer unit 110, the opening/closing unit 130, and the cleaning unit 140 minimize the maximum cleaning effect. ) can be controlled.

Meanwhile, the processor 160 according to another embodiment sets the light intensity of ultraviolet light emitted from the cleaning unit 140 to be changed based on information on the opening degree of the first door unit 131 and the second door unit 132. The government 140 can be controlled.

Here, the opening degree information may be information indicating the open state of each of the first door part 131 and the second door part 132, and the degree of opening may be represented by any one numerical value from 0% to 100%. . For example, if the opening degree information of each of the first door part 131 and the second door part 132 is 0%, it means that the first door part 131 and the second door part 132 are closed. , When the opening degree information of each of the first door unit 131 and the second door unit 132 is 100%, the first door unit 131 and the second door unit 132 are opened to the maximum open state. can mean a state of being.

The processor 160 according to another embodiment adjusts the light intensity of the ultraviolet light irradiated from the cleaning unit 140 to decrease as the degree of opening indicated by the information about the degree of opening of the first door unit 131 and the second door unit 132 increases. The cleaning unit 140 may be controlled.

Through this, it is possible to minimize a phenomenon in which the first door unit 131 and the second door unit 132 are opened to leak ultraviolet rays to the outside.

The processor 160 may perform the operation of each of the above-described components, and a connection path for transmitting and receiving signals to and from one or more cores (not shown) and a graphics processing unit (not shown) and/or other components (eg, For example, a bus, etc.).

The processor 160 may be configured to perform the operation of each component described above by executing one or more instructions stored in the storage unit 170 .

The storage unit 170 may store programs (one or more instructions) for processing and control of the processor 160 . Programs stored in the storage unit 170 may be divided into a plurality of modules according to functions.
