Therefore, it is possible to provide a spear removing device that eliminates the need to process the constituent body and removes the spear adhering over a wide range of the constituent body.

  In the above-described spear removing apparatus, the positioning means is a means for positioning a plurality of the arranging means with respect to the component.

  According to this spear removing device, since the plurality of disposing means are positioned with respect to the constituent by the positioning means, it is possible to efficiently irradiate a wider range of spears with blue visible light, It is possible to improve the efficiency of the removal process.

  The above-described spear removing apparatus has moving means for moving the arranging means relative to the component.

  Hereinafter, an embodiment of the above-described spear removing apparatus of the present invention will be described with reference to the drawings of FIGS.

  1 to 3, the spear removing apparatus 1 includes an irradiation unit 10, a placement unit 20 as the placement unit, a positioning unit 30 as the positioning unit, and a moving unit 40 as the moving unit. is doing. The spear removing device 1 removes the spear 3 by irradiating a visible light 5 having a blue wavelength to the spear 3 attached to a component such as a front panel 2 of a car stereo.

  The irradiation unit 10 includes a plurality of blue lasers 11 as the light beam irradiation unit and a light source control circuit 12. In the present embodiment, a case where 35 blue lasers 11 are used as shown in FIG. 3 will be described, but the number can be arbitrarily set.

  Here, as a result of attaching cigarette dust to the acrylic substrate and measuring the light absorption characteristics in the film portion of the cigarette, the measurement results shown in FIG. 4 were obtained. In addition, as a measuring method of a light absorption characteristic, using the irradiation apparatus which irradiates visible light 5 by changing a wavelength in the range of 0.45 μm to 0.9 μm, the amount of light incident on the Yani film and the Yani film are determined. The light absorption rate is obtained based on the difference in the amount of transmitted light.

  As a result, as shown in FIG. 4, it was confirmed that light having a wavelength of 0.6 μm or less was absorbed. In other words, it was possible to pursue that the cigarette dust absorbed visible light 5 having a wavelength corresponding to blue and green. And since the light absorptance of 0.5-0.55 micrometer vicinity is large, it is thought that it is efficient to use the visible light 5 of the wavelength corresponding to the wavelength band among visible light.

(test)
Next, in order to verify the relationship between the light absorption rate of the above-mentioned spear and the change in yellowing, the spear of the cigarette 3 attached on the acrylic substrate as a constituent using a red LED, a blue LED, and a blue LD. Moreover, the test which evaluates visually the change of the spear on an acrylic substrate for every predetermined time was performed by irradiating each visible light. The evaluation environment was 20 ° C. and 65% RH. The evaluation results are shown in Table 1 below.

The irradiation power of each light source is 0.8 mW for the red LED, 2 mW for the blue LED, and 10 mW for the blue LD. The wavelength of each light source is 650 nm for red LED, 470 nm for blue LED, and 408 nm for blue LD. And it evaluated every 0, 24, 48, 72, 96, 227 hours from the start. However, the evaluation criteria in Table 1 are:
○: Change in the yellowing of the spear ×: No change in the yellowing of the spear.

  Looking at Table 1, the following can be understood. In other words, when yellow visible light is irradiated, there is no change in the yellowing of the jade, whereas when irradiated with blue visible light 5, the yellowing of the jain changes in about 24 hours, and the yellowing becomes almost colorless. It was. That is, it is considered that the spear has been removed. And when considering the ratio of irradiation power between the red LED and the blue LED, there is a difference of about 2.5 times, and in the case of the blue LED, although the yellowing removal effect has already been observed in 24 hours, The red LED shows no change in yellowing even after 227 hours. That is, if it reacts with a red LED, if estimated from the ratio of irradiation power, a change should be observed around 60 hours later.

  Therefore, it can be considered that the light can be removed by irradiating the blue visible light 5 with the characteristic of light absorption of the light. Considering this test result, the blue laser 11 can be configured as follows.

  The blue laser 11 is a blue LD, and serves as a light irradiation unit that emits visible light 5 having a wavelength of 0.408 μm, for example, based on the test result of FIG. The blue laser 11 is electrically connected to a light source control circuit 12 provided in the arrangement unit 20, and is turned on and off by the light source control circuit 12.

  In this embodiment, the case where the blue laser 11 is used will be described. However, the present invention is not limited to this, and a blue LED and a green light source are used alone, or a blue LED and a green light source are used in combination. Various embodiments can be made such as using a normal light source and a filter that transmits only visible light 5 having a wavelength of 0.4 to 0.6 μm.

  The light source control circuit 12 drives the blue laser 11 in response to an external request, and stabilizes the amount of visible light 5 emitted from the blue laser 11 based on a feedback signal input from a monitor diode (not shown). Is adjusting.

  The irradiation unit 10 configured in this manner irradiates a predetermined irradiation region E so that the amount of light is uniform when the visible light 5 having a wavelength of 0.408 μm, for example, is emitted from each blue laser 11.

  As shown in FIG. 3, the placement unit 20 includes a base member 21 and a plurality of mounting holes 22 provided in the base member 21.

  The base member 21 is formed in a substantially rectangular box shape corresponding to the irradiation region E described above, and the inside thereof has a structure for accommodating and fixing the light source control circuit 12. The mounting hole 22 has a structure in which each of the plurality of blue lasers 11 described above protrudes to the outside according to the assembly of the light source control circuit 12. That is, a number of mounting holes 22 corresponding to the number of blue lasers 11 are formed on one surface of the base member 21.

  Thus, the arrangement unit 20 arranges the plurality of blue lasers 11 with respect to the front panel 2 to form a surface light source module including the plurality of blue lasers 11. As a result, the blue-colored visible light 5 from the blue laser 11 can be irradiated to a wide range of spears 3.

  As shown in FIGS. 1 and 2, the positioning unit 30 includes a conveyance base member 31, a plurality of (four in FIG. 2) expansion / contraction units 32, an arm unit 33, a suction unit 34, and a movable unit 35. ,have. In addition, about the number of the expansion-contraction parts 32, the arm parts 33, etc., it can set arbitrarily.

  The transport base member 31 is formed of a synthetic resin or the like in a flat plate shape slightly larger than the base member 21, and the base member 21 is attached to one surface. Each of the telescopic portions 32 includes a cylinder 32a and a reciprocating member 32b that reciprocates within the cylinder 32a. One end of the cylinder 32 a is fixed to the transport base member 31 by a movable portion 35 so as to be rotatable. At the end of the reciprocating member 32b that protrudes outside the cylinder 32a, an arm portion 33 that extends toward the front panel 2 stands. As the expansion / contraction part 32, a member that can be expanded / contracted in the expansion / contraction direction M by a moving mechanism (not shown) according to a drive signal is used.

  The arm part 33 has a substantially columnar shape and has a strength capable of holding the irradiation part 10, the arrangement part 20, and the like. The suction part 34 is an ordinary suction cup that creates a vacuum inside by the suction force of the sucker rubber, or a strong suction cup that creates a vacuum inside by the force that the lever pulls the rubber, and is provided at the end of the arm part 33. Yes. In addition, when the dust removing apparatus 1 performs a dust removing operation such as a wall or a ceiling, it is preferable that the suction portion 34 is configured by a stronger suction member. A device capable of switching control of the adsorption free state is used.

  The movable portion 35 pivotally supports one end of the expansion / contraction portion 32 and has a structure that can rotate the expansion / contraction portion 32 and the like by an arbitrary angle. That is, by controlling the rotation of a motor and a rotation mechanism (not shown) by a control device, the expansion / contraction part 32 and the like can be positioned at an arbitrary angle.

  For example, as shown in FIG. 5A, when the other end portions of the four stretchable portions 32, that is, the suction portions 34 are located at positions P1, P2, P3, and P4, the stretchable portions 32 are stretched. By doing so, the conveyance base member 31 can be moved in the Y direction in FIG. Then, in the case of moving in the X direction in FIG. 5, the telescopic part 32 and the like are rotated by about 90 degrees in the rotation direction R with the movable part 35 as the rotation center, so that FIG. As shown in FIG. 4, each of the adsorption portions 34 is positioned at P1 ′, P2 ′, P3 ′, and P4 ′.

  By configuring the positioning unit 30 in this manner, the placement unit 20 can be positioned at an arbitrary position from the front panel 2 corresponding to the length of the arm unit 33. In other words, by arbitrarily setting the length of the arm portion 33, the interval between the arbitrary front panel 2 and the placement portion 20, that is, the irradiation portion 10 can be set.

  Further, since the movable portion 35 for moving the suction portion 34 relative to the front panel 2 is provided in the positioning portion 30, the vertical front panel can be obtained by moving the suction portion 34 by the movable portion 35. Since the spear removing apparatus 1 can be moved even when the speed is 2, the application range of the spear removing work can be improved.

  The moving unit 40 includes a plurality of (four in FIG. 2) wheels 41 and a wheel holding unit 42 that holds the wheels 41 in a freely rotatable manner. The wheel 41 is rotated in a predetermined direction by a drive mechanism (not shown). The wheel holding portion 42 rotatably holds the wheel 41 at one end side, and the other end side is fixed to the transport base member 31.

  By configuring the moving unit 40 in this way, when the plurality of wheels 41 are rotated in the expansion / contraction direction M of the expansion / contraction part 32, the wheel holding unit 42 is also moved by the rotation. The transport base member 31 to which is fixed also moves. And since the conveyance base member 31 is being fixed to the expansion-contraction part 32, the arrangement | positioning part 20 located with respect to the front panel 2 is moved to the expansion-contraction direction M within the expansion-contraction range of the expansion-contraction part 32 of the positioning part 30. be able to.

  Next, an example of the movement operation of the above-described spider removing device 1 will be described below with reference to the drawing of FIG. In FIG. 6, the same parts as those in FIG.

  First, when moving the conveyance base member 31 of the stain removing apparatus 1, that is, the arrangement portion 20 in the Y direction in FIG. 6, the stain removing apparatus 1 is arranged on the front panel 2 as shown in FIG. When the movement in the Y direction is requested by an operator or the like, all of the suction portions 34 at the positions P1 to P4 are in the suction state, and the blue visible light 5 from the irradiation portion 10 is applied to the front panel 2. Irradiation is applied to the spear 3 attached to the surface or the like. Then, when the irradiation of the visible light 5 determined in advance is reached, the suction of the suction part 34 at the positions P1 and P2 is freely changed, and the expansion / contraction part 32 corresponding to them is extended, thereby FIG. 6B. As shown in FIG. 4, the arm portion 33 moves in the Y direction.

  As shown in FIG. 6C, the suction part 34 at the positions P1 and P2 is in the suction state and the suction part 34 at the positions P3 and P4 is changed to suction-free, and the moving part 40 is driven to move in the Y direction. Further, the transport base member 31 moves in the Y direction. And according to completion | finish of this movement, the adsorption | suction part 34 of position P3, P4 is changed to an adsorption state. In this way, the transport base member 31, that is, the placement unit 20 has moved in the Y direction by about ½ of its size.

  Thereafter, the suction of the suction part 34 at the positions P1 and P2 is freely changed, and by extending the expansion / contraction part 32 corresponding to them, the arm part 33 moves in the Y direction as shown in FIG. 6 (d). It will be. Then, the suction part 34 at the positions P1 and P2 is changed to the suction state and the suction part 34 at the positions P3 and P4 is changed to suction-free, and the moving part 40 is driven to move in the Y direction. As shown, the transport base member 31 moves in the Y direction. And according to completion | finish of this movement, the adsorption | suction part 34 of position P3, P4 is changed to an adsorption state. In this way, the transport base member 31, that is, the placement unit 20 has moved in the Y direction by one size.

  By repeating such a series of operations, the transport base member 31, that is, the placement unit 20 moves in the Y direction. When moving in the X direction, as shown in FIG. 5, the contraction portion 32 is rotated in the X direction, and the contraction portion 32 and the suction portion 34 are controlled as described above, whereby the transport base member 31 is controlled. That is, the placement unit 20 can be moved in the X direction.

  In this way, the spear removing device 1 moves the disposition unit 20 positioned with respect to the front panel 2 within the predetermined range defined by the expansion / contraction part 32 of the positioning unit 30, and thus the predetermined range. Can be set as the removal range of the spear 3, so that it can be efficiently moved with respect to the front panel 2, and an efficient spear removal operation can be performed.

  Next, using the spear removing device 1 having the above-described configuration, the spear removing device 1 is moved as shown in FIG. 7 with respect to the spear 3 attached to the front panel 2 of a car stereo or the like, and the change is clarified. Therefore, an example of the operation (action) in the case where the blue visible light 5 is irradiated from the irradiation unit 10 only at the three positions will be described below.

  The spear removing apparatus 1 moves in the order of the area E1, the area E2, and the area E3 of the front panel 2 as described above. Then, the movement is stopped in each of the regions, and the plurality of blue lasers 11 arranged by the arrangement unit 20 only in that region are caused to emit light for a predetermined irradiation time, thereby causing the irradiation unit 10 to the spear 3 The blue visible light 5 was irradiated toward the irradiation time. In addition, the irradiation time is arbitrarily determined according to the density of the spear 3 attached to the front panel 2.

  Then, in FIG. 8 in which the area E1 of the front panel 2 before irradiation with the visible light 5 is enlarged and imaged, the yellow portion due to the adhesion of the spider 3 and the pattern portion of the front panel 2 are shown as blackened. Has been. And after irradiating visible light 5 over irradiation time, in FIG. 9 which imaged the same part as FIG. 8, it has confirmed that the part which yellow 3 adhered and the yellowing part disappeared, and it changed to white. . Similar results were confirmed for each of the other regions E2 and E3.

  That is, it is shown that the spear 3 has been removed by irradiating the blue visible light 5. As a result, as shown in FIG. 7B, it was confirmed that the spear 3 in each of the regions E1 to E3 was removed and the surface of the front panel 2 was changed to the exposed region C. Therefore, it can be said that the spear 3 irradiated with the visible light 5 absorbs the visible light 5, and thus the spear 3 is removed by the energy of the absorbed light.

  According to the spider removing apparatus 1 described above, a plurality of blue lasers 11 are disposed by the disposing unit 20, and the disposing unit 20 is positioned with respect to the front panel 2 so that the plurality of blue lasers 11 can be irradiated to the spear. As a result, the blue visible light 5 can be irradiated over the wide range of the front panel 2, so that the wide range of resin 3 can be efficiently removed. In addition, it is only necessary to irradiate the spigot 3 with visible light 5 having a blue wavelength, and since a photocatalyst is previously formed on the front panel 2 side as in the prior art, an apparatus for irradiating ultraviolet rays there is no longer necessary. It becomes possible to increase the degree of freedom of the material of the front panel 2, and it is possible to remove the spear 3 attached to everything such as cloth, paper, and a panel of an electronic device. Moreover, since it is only necessary to irradiate light, the spear 3 attached to the fine irregularities formed on the front panel 2 can also be removed. Therefore, it is possible to provide a spear removing device 1 that eliminates the need to process the front panel 2 and removes spear adhering over a wide range of the structure.

  According to this spear removing device 1, since the plurality of blue lasers 11 are moved relative to the front panel 2 by the moving unit 40, the visible light 5 is concentratedly irradiated on the wide spur 3. As a result, it is possible to efficiently remove the scum adhering to a wide range sequentially.

  According to this spear removing device 1, the suction portion 34 is provided in the positioning portion 30 so that the spear removing device 1 is sucked to the front panel 2. However, since the removal operation | work of a spear can be performed, the application range of a structure can be improved.

  In this way, the above-described spear removing apparatus 1 has a blue visible light beam 5 on a structure in a place where human hands cannot reach, such as an indoor wall, in addition to a structure made of a synthetic resin such as the front panel 2. Suitable for irradiation.

  In the above-described spear removing device 1, the case where one positioning unit 20 is positioned with respect to the front panel 2 by the positioning unit 30 has been described. However, the present invention is not limited to this, and for example, illustrated in FIG. 10. As described above, by attaching a plurality (four in FIG. 10) of the placement units 20 to the transport base member 31, the positioning unit 30 positions the plurality of placement units 20 with respect to the front panel 2, for example. be able to. With such a configuration, it is possible to efficiently irradiate an even wider range of blue-colored visible light, and thus it is possible to improve the efficiency of the removal process.

  Further, in the above-described spear removing apparatus 1, the case where the arrangement portion 20 is formed in a rectangular shape has been described. However, the present invention is not limited to this, and for example, the arrangement portion 20 is formed in a substantially circular shape as shown in FIG. 11. Various embodiments such as forming can be made. In addition, a plurality of circular arrangement portions may be provided on the above-described transport base member 31.

  As described above, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
