On the other hand, the main body 11 further includes an operation unit 12 for the user's operation, and a display unit 14 for displaying the inspected seaweed state.

Hereinafter, the structure of the lighting unit will be described in detail.

FIG. 3 is a perspective view of the first lighting unit, FIG. 4 is a cross-sectional view taken along AA of FIG. 3 when the first lighting unit projects the upper surface of the seaweed, FIG. 5 is a perspective view of the second lighting unit, and FIG. 5 is a cross-sectional view taken along the BB of FIG. 5 when the lighting unit projects the lower surface of the laver.

1 to 6, the first lighting unit 31 includes a case 310, light sources 311 and 312 accommodated in the case 310, and light generated from the light sources 311 and 312. These incident, refracting portions 313 and 314 for refracting the incident light to the seam surface are included.

In addition, the first lighting unit 31 further includes a lower glass 315 and an upper glass 316 forming upper and lower surfaces of the first lighting unit 31 and sealing the first lighting unit 31. do.

The light source units 311 and 312 may include a left light source unit 311 and a right light source unit 312, and each of the light source units 311 and 312 may be installed on the circuit boards 311a and 312a to receive electricity. The refraction parts 313 and 314 include a left refraction part 313 and a right refraction part 314.

The left refraction portion 313 and the right refraction portion 314 are spaced apart from each other by a predetermined interval. Therefore, a space for passing light is formed between the left refraction portion 313 and the right refraction portion 314.

That is, the space provides a space in which light reflected from the seam surface can be incident to the first inspection camera 41.

The light source units 311 and 312 include a plurality of light emitting diodes (LEDs).

In the light source units 311 and 312, a plurality of LEDs are arranged in a plurality of rows. For example, FIG. 4 includes a plurality of LEDs arranged in three rows. In addition, a plurality of LEDs are spaced apart from each other.

However, the method of arranging the light source units 311 and 312 is not limited thereto, and there may be various methods.

The left and right light sources 311 and 312 are provided at the left and right refraction parts 313 and 314, respectively.

Accordingly, light generated by the light source units 311 and 312 is incident on the refracting units 313 and 314.

Each of the refracting portions 313 and 314 is formed of a medium through which light can travel. Each of the refracting portions 313 and 314 may be, for example, acrylic.

The left refraction portion 313 includes a first refraction surface 313a, and the right refraction portion 314 includes a second refraction surface 314a. Each of the refracting surfaces 313a and 314a is formed to be inclined at the respective refracting portions 313 and 314.

Each of the refracting surfaces 313a and 314a is inclined in a direction away from each other from the upper side to the lower side. This is for light to be irradiated to the seam surface positioned between each of the refractive surfaces 313a and 314a. The arrangement relationship of the refractive surfaces 313a and 314a can be clearly understood by FIG. 4.

The refractive surfaces 313a and 314a are sanded. This is to uniformly diffuse the brightness of the light in the fold surface (313a, 314a).

Light incident on the refracting portions 313 and 314 travels along the refracting portions 313 and 314. Light propagating along each of the refraction portions 313 and 314 is transmitted to the refraction surfaces 313a and 314a and diffuses from the refraction surfaces 313a and 314a.

Therefore, the light emitted from each of the light source parts 311 and 312 may be evenly irradiated onto the seam surface.

As described above, light emitted from each of the light sources 311 and 312 is diffused and refracted while passing through each of the refracting units 313 and 314 to be irradiated onto the seaweed surface, thereby enabling indirect illumination of seaweed.

Since the laver shape itself has many curved surfaces, diffuse reflection of light may occur on the surface of the laver by direct illumination, but when indirectly illuminated as in the present embodiment, the diffuse reflection may be reduced.

In addition, the light irradiated onto the surface of the sea is incident on the first inspection camera 41 through a space formed between the left light source 311 and the right light source 312.

That is, the upper surface of the laver surface which is indirectly illuminated by the first lighting unit 31 may be inspected by the first inspection camera 41 which is spaced at a predetermined interval above the first lighting unit 31.

The foreign material inspection of the laver surface is performed by comparing the degree of reflection of the laver color and the foreign matter different from the laver color.

Meanwhile, the second lighting unit 32 includes cases 320a and 320b, light source units 323 and 324 accommodated in the cases 320a and 320b, refraction units 321 and 322, and an infrared ray generator 326. Included.

Since the structure of the light source unit 323 and 324 and the refraction unit 321 and 322, the path of light and the operation of the second inspection camera 42 are the same as those described in the first lighting unit 31, detailed description thereof will be omitted. do.

The infrared rays generator 326 emits infrared rays from the bottom of the steam to the top. The fourth inspection camera 44 is disposed above the infrared generator 326. In addition, the infrared ray generator 326 may be installed on the circuit board 326a to receive electricity.

In the present embodiment, the infrared generator 326 has been described as being provided in the second lighting unit 32, but may be provided independently of the second lighting unit 32. The infrared ray generator 326 includes a plurality of infrared LEDs and one or more diffusion parts 327a and 327b provided above the plurality of infrared LEDs.

In this embodiment, for example, two diffusion parts 327a and 327b are disclosed, and the two diffusion parts 327a and 327b are spaced up and down. The diffusion parts 327a and 327b may be formed of acryl, for example.

The infrared ray is transparent. However, there is a difference in permeability depending on the thickness of the material. For example, the infrared rays may transmit seaweed, and foreign substances such as styrofoam, straw, and shellfish inside the seam may not pass through.

That is, the infrared rays emitted from the infrared ray generator 326 may reach the fourth inspection camera 44 located on the opposite side through the seaweed only when there is no foreign matter in the steam being transferred. Therefore, according to the infrared ray generator 326, it is possible to inspect the foreign matter present in the steam.

On the other hand, the third inspection camera for inspecting the presence of the hole and the torn portion of the surface of the seam is located on the upper side of the second illumination unit 32 that emits light on the bottom surface of the seam spaced apart from the second illumination (32) ( 43) is arranged.

Alternatively, the third inspection camera 43 may be disposed at a predetermined distance from the first illumination unit 31 below the first illumination unit 31 that emits light on the upper surface of the seaweed. Even in this case, only the arrangement of the lighting unit and the inspection camera is different, and the function of the third inspection camera 43 which inspects the existence of holes and torn portions of the seam surface does not change.

When the hole is formed in the seam surface, the light emitted from the second lighting unit 32 is irradiated upward through the hole of the seam surface. The light irradiated in this way is incident on the third inspection camera 43 and the light incident on the third inspection camera 43 makes it possible to determine whether or not there is a hole in the seam surface.

At this time, since the light refracted by one of the refracting surfaces 322a and 322b of the second lighting unit 32 is irradiated upward through the lattice hole, the third light is easily detected to upwardly irradiate upward. The inspection camera 43 may be disposed to be inclined at an angle with respect to the vertical line up and down.

In the case of a conventional laver foreign matter sorting device, the light emitted from the light source of the lighting unit is reflected on the surface of the seaweed by the way reflected by the reflector.

As described above, when the light is reflected, the size of the lighting unit is increased, and there is a problem that the light is uniform and the brightness of the light is not uniform according to the reflection point.

However, according to the proposed embodiment, since the light generated from the light source unit is refracted by the refraction unit and is incident on the surface of the sea rather than reflecting light, the uniformity and brightness of the light are uniform, and the illumination unit occupies the conventional lighting unit. The advantage is that the space is small.

In addition, since a plurality of light source parts are formed in a symmetrical shape and simultaneously illuminates the laver surface, there is an advantage of increasing efficiency.

In addition, there is an advantage to inspect the foreign matter present in the steam as well as the surface of the steam using the infrared LED.
