Embodiment 1 FIG.
FIG. 1 is a schematic cross-sectional view for explaining the structure of a liquid crystal television disassembled by the disassembling method of the liquid crystal television of the first example according to Embodiment 1 of the present invention and the cutting position of the liquid crystal television in this disassembling method.
FIG. 2 is a schematic front view illustrating the structure of the liquid crystal television disassembled by the disassembling method of the liquid crystal television of the first example according to Embodiment 1 of the present invention and the cutting position of the liquid crystal television in this disassembling method.
The structure of the liquid crystal television shown in FIG. 1 and FIG. 2 is a typical structure of a large-sized liquid crystal television (20 type or more) that is heavy and difficult to disassemble. FIG. 1 shows a state in which main components are separated. Yes.

Next, the structure of the liquid crystal television 1 and the main components of the liquid crystal television 1 will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, in the liquid crystal television 1, a back panel 5 that is a design part on the back side and a frame 2 that is a strength member are joined by screws 7. A control / drive printed circuit board 3 and a liquid crystal unit 4 serving as a display device are fixed to the surface of the frame 2 opposite to the joint surface with the back panel 5.

In addition, a front panel 6 which is a front side design component is fixed to the back panel 5 with screws 7.
The front panel 6 has an opening, and the screen of the liquid crystal unit 4 is exposed from the opening to cover the liquid crystal unit 4.
As shown in FIG. 2, in a self-supporting liquid crystal television, a leg portion 8 for allowing the main body to stand on the outside or inside of the back panel 5 is fixed with screws.

The liquid crystal unit 4 includes a fluorescent lamp 11 serving as a backlight and a resin-made diffusion plate that diffuses and uniforms the light of the fluorescent lamp 11 on a liquid crystal unit case 10 formed of a metal sheet that houses components of the liquid crystal unit 4. A class 12, an intermediate lid 13, and a liquid crystal panel 14 are mounted in this order, and these are covered with a liquid crystal unit lid 15 formed of a metal sheet metal. The liquid crystal unit case 10 and the liquid crystal unit lid 15 are fixed by a liquid crystal unit fixing screw 16 at a position outside the outer periphery of the liquid crystal panel 14.
The fluorescent lamp 11 is attached to the liquid crystal unit case 10 with a fluorescent lamp holder 11a.

  In these components of the liquid crystal unit 4, the liquid crystal panel 14 may contain harmful substances such as antimony or arsenic, and the fluorescent lamp 11 contains harmful substances such as mercury. In dismantling the television 1, it is necessary to reliably separate the liquid crystal panel 14 and the fluorescent lamp 11 from each other.

  For this reason, in disassembling the conventional liquid crystal television, first, the screws 7 of the back panel 5 and the front panel 6 are removed, the design parts are removed, and then the liquid crystal unit fixing screws 16 are removed to disassemble the liquid crystal unit 4; The liquid crystal panel 14 and the fluorescent lamp 11 were removed.

However, the screws used to fix the components of the liquid crystal television may exceed 100 in large models, and in the conventional disassembly method, it is necessary to confirm and remove the screw position of the liquid crystal television. It took an enormous amount of work to remove.
In addition, the screw position of LCD TVs varies depending on the product or size, so it is difficult to accurately detect the screw position without mistakes with current image processing technology. This is a bottleneck in automating disassembly. It was.

  In the first example of the method of disassembling the liquid crystal television of the present embodiment, the liquid crystal television 1 is cut in the range from the front panel 6 to the back panel 5 at the position of the cutting line A1 shown in FIGS. This includes a step of contacting and separating the four outer edges of the television 1. The cutting line A <b> 1 is located outside the outer periphery of the liquid crystal panel 14 and inside the screw fixing portion of the liquid crystal unit lid 15, and is substantially parallel to each side of the liquid crystal panel 14.

That is, the disassembling method of the liquid crystal television of the first example of the present embodiment includes a step of cutting a portion of the liquid crystal television 1 outside the outer periphery of the liquid crystal panel 14 and inside the screw fixing portion in the liquid crystal unit lid 15. It is provided.
In particular, the range from the front panel 6 to the back panel 5 is cut at a portion outside the outer periphery of the liquid crystal panel 14 and inside the screw fixing portion in the liquid crystal unit lid 15, and the four outer edge sides of the liquid crystal television 1 are cut off. It is provided with a process of contacting and separating.

Since the disassembling method of the liquid crystal television of the first example of the present embodiment includes such steps, the front panel 6 can be removed without removing the screws 7.
Further, since the liquid crystal unit lid 15, the intermediate lid 13, and the fluorescent lamp holder 11a are separated at the position of the cutting line A1, the inside of these cut portions can be removed without removing the liquid crystal unit fixing screw 16. It becomes.

Then, the liquid crystal panel 14 can be removed by removing the inside of the cut portion of the liquid crystal unit lid 15, and the diffusion plate 12 and the fluorescent lamp 11 can be removed by removing the inside of the cut portion of the intermediate lid 13. Can be removed.
That is, the liquid crystal panel 14 containing the harmful substance and the fluorescent lamp 11 can be surely removed without carrying out the screw removing operation which takes a huge amount of work time.

The inventors investigated the structure of the collected waste liquid crystal televisions, and there are significant differences in the structure of the design parts, depending on the design features such as the manufacturer, manufacturing age, or speaker position. The liquid crystal unit 4 was found to have almost the same structure.
The common structure of the liquid crystal unit 4 found by the inventors is that the outer size of the liquid crystal panel 14 is 10 to 20 mm larger on the left and right and 2 to 10 mm on the upper and lower sides with respect to the size of the display portion of the image. It ’s getting bigger.

  That is, the cut portion outside the outer periphery of the liquid crystal panel 14 and inside the screw fixing portion in the liquid crystal unit lid 15 is not affected by the liquid crystal television having a different design such as the mounting position of the speaker 9 or the like. Since it can be easily determined as the distance from the edge of the screen, which is the display portion of the image, the liquid crystal television disassembly method of this embodiment can be automated.

  In addition, if the liquid crystal panel 14 and the fluorescent lamp 11 containing harmful substances are removed, the remaining part can be used in a dismantling method with advanced labor saving and automation such as crushing. It is easy to automate dismantling.

FIG. 3 is a schematic cross-sectional view illustrating the structure of a liquid crystal television disassembled by the disassembly method of the liquid crystal television of the second example according to Embodiment 1 of the present invention and the cutting position of the liquid crystal television in this disassembly method.
In the liquid crystal television, the front panel 6, the liquid crystal unit lid 15, the intermediate lid 13, and the fluorescent lamp holder 11a are cut at a portion outside the outer periphery of the liquid crystal panel 14 and inside the screw fixing portion of the liquid crystal unit lid 15. If possible, the liquid crystal panel 14 and the fluorescent lamp 11 can be removed without removing the screws 7 and the liquid crystal unit fixing screws 16.

  Therefore, the disassembling method of the liquid crystal television of the second example of the present embodiment, instead of cutting the liquid crystal television 1 from the front panel 6 to the back panel 5 and contacting and separating the four outer edge sides of the liquid crystal television 1, As shown by the cutting line A2 in FIG. 3, the outer side of the outer periphery of the liquid crystal panel 14 and the inner side of the screw fixing portion in the liquid crystal unit lid 15 are cut from the front panel 6 side to the fluorescent lamp holder 11a. It has a process of making a cut.

In this case, it is not necessary to cut the liquid crystal unit case 10, the frame 2, and the back panel 5, and the cutting time can be shortened.
Further, since the cutting depth becomes shallow, for example, cutting using a rotating grindstone has advantages that it is possible to suppress wear of the grindstone and to reduce the output of the rotating motor of the rotating grindstone.

Examples of the push-up means 26 include those in which the base portion 26a and the height adjusting portion 26b form an air cylinder structure, a screw structure, and a rail structure.

In the present embodiment, as shown in FIG. 6, the reference member 27 is detachably fixed to the upper surface of the side surface position restricting portion 28c in the fixing means 28 with the pressing mechanism.
Since each fixing mechanism-equipped fixing means 28 has the same size, each reference member 27 is arranged in the same plane parallel to one surface of the mounting base 17.

In FIG. 6, only the reference member 27 in the two fixing means 28 with the pressing mechanism facing each other is shown, but the fixing means with the pressing mechanism on the upper long side, the fixing means with the pressing mechanism on the lower long side, and the right The fixing means 28 with the pressing mechanism on the short side and the fixing means 28 with the pressing mechanism on the left short side are installed on the fixing means 28 with the pressing mechanism.
Further, since the reference member 27 is detachably fixed to the fixing means 28 with the pressing mechanism, it can be removed when the liquid crystal television is cut, can be retracted from the front panel surface, and does not interfere with the cutting means 21.

In the present embodiment, as shown in FIG. 6, the distance measuring sensor 24 attached to the moving means 25 moves in a direction indicated by an arrow G, for example, parallel to one surface of the mounting base 17. The beam F from the distance measuring sensor 24 scans the surface of the front panel 6 and the liquid crystal surface of the liquid crystal television 1.
The moving means 25 may be provided with means for rotating and fixing at an arbitrary angle in a plane parallel to one surface of the mounting base 17.

As shown in FIG. 2, in a self-supporting liquid crystal television, a leg portion 8 that makes the main body stand on the outside or the inside of the back panel 5 is fixed with screws.
In addition, there are many liquid crystal televisions having a back panel surface that is uneven, such that a protruding portion of a speaker portion, a Blu-ray disc drive or DVD installation portion, and the like are provided on the back panel.

FIG. 9 is a schematic side view showing a state in which a liquid crystal television having leg portions and having an uneven back panel is directly placed on a mounting base.
As shown in FIG. 9, when the liquid crystal television 51 having the legs 8 and the back panel 55 being uneven is directly placed on the mounting base 17, the liquid crystal television 51 is fixed in an inclined posture.
Further, even in the case of a liquid crystal television without a leg portion or a liquid crystal television without a leg portion, as shown in FIG. 9, a protruding portion 30 of a speaker portion, a Blu-ray disc drive or DVD installation portion (disc If the back panel 55 is uneven, the liquid crystal television is fixed to the dismantling device of the liquid crystal television in an inclined posture.

  That is, the back panel is uneven, and when the liquid crystal television is fixed to the mounting base 17 in a tilted posture, the surface of the mounting base 17 on one side of the liquid crystal television (for example, the leg side) to the surface of the front panel 6. Therefore, it is necessary to use a distance measuring sensor 24 having a wide measurement range because the height (referred to as the mounting height) of the other and the mounting height on the other side (for example, the ceiling side) are different. At the time of cutting, it is necessary to correct the position of the vertical axis 23 of the cutting means according to the tilt of the liquid crystal television.

There is a level difference of about 2 to 10 mm between the surface of the front panel 6 and the liquid crystal surface of the liquid crystal television, but the surface of the front panel 6 and the liquid crystal surface are substantially parallel.
In the dismantling device of the liquid crystal television, when the height of the liquid crystal surface is continuously measured by the distance measuring sensor 24, the measured value of the height changes abruptly at the level difference between the liquid crystal surface and the front panel 6. When this change position is recognized, it is possible to confirm the screen edge position.

FIG. 10 is a diagram showing a state (a) and a step detection position (b) in which a step sensor between the front panel and the liquid crystal surface is measured by a distance measuring sensor when the liquid crystal television is fixed to the mounting base in an inclined posture. It is.
As shown in FIG. 10B, the detection position L1 of the step D1 between the liquid crystal surface 4a and the front panel 6 when the liquid crystal television indicated by the solid line is fixed to the mounting base 17 in an inclined posture is 2 When the liquid crystal television indicated by the dotted line is fixed to the mounting base 17 in a parallel posture, it is closer to the liquid crystal surface 4a than the detection position L2 of the step D2 between the liquid crystal surface 4a and the front panel 6 surface.

That is, since the step detection position is the screen end position of the liquid crystal television, the screen end position when the liquid crystal television is fixed to the mounting base 17 in an inclined posture is the case where the liquid crystal television is fixed to the mounting base 17 in a parallel posture. Deviation from the screen edge position.
When the screen edge position is shifted to the outside, the cutting position is shifted and the outside of the center of the screw in the liquid crystal unit lid 15 may be cut, and the liquid crystal unit 4 cannot be separated.
Further, even when the screen edge position is shifted inward, there is a possibility that the cutting position is shifted and the liquid crystal panel 14 and the fluorescent lamp 11 containing harmful substances are cut.

FIG. 11 is a schematic side view showing a state in which a liquid crystal television set with an uneven back panel is set in the dismantling apparatus for a liquid crystal television set according to Embodiment 4 of the present invention.
FIG. 11 shows the mounting base 17, the push-up means 26, and the reference member 27 in the dismantling apparatus 300 for the liquid crystal television.
In addition, FIG. 11 shows the liquid crystal television 51 in which the back panel 55 is uneven, but the legs are omitted.

As shown in FIG. 11, the dismantling apparatus 300 for the liquid crystal television of the present embodiment holds the back panel 55 of the liquid crystal television 51 by the mounting portion 26 c of the push-up means 26. Then, the height adjusting unit 26 b of the push-up means 26 is extended to push up the liquid crystal television 51, and the front panel 6 of the liquid crystal television 51 is brought into contact with the reference member 27.
Next, although not shown, the fixing means 28 with a pressing mechanism presses the side surface position regulating portion 28c against the side surface of the liquid crystal television 51 by the side surface position adjusting portion 28b to fix the liquid crystal television 51.

  That is, in the dismantling apparatus 300 for the liquid crystal television of the present embodiment, the extension amount of the height adjusting portion 26b of the push-up means 26 is adjusted regardless of whether the leg portion is provided or the back panel is uneven. As a result, the liquid crystal television 51 is pushed up until the front panel 6 comes into contact with each reference member 27 arranged in the same plane parallel to one surface of the mounting base 17, and the fixing means 28 with the pressing mechanism is used. Since it is fixed, the liquid crystal television 51 is set with its front panel surface and liquid crystal surface both parallel to one surface of the mounting base 17.

In the liquid crystal television disassembling apparatus 300 of the present embodiment, the liquid crystal television can be set without being tilted, so that the measurement range of the distance measuring sensor 24 can be limited to, for example, 20 mm or less, so that the measurement resolution can be improved and inexpensive measurement is possible. Even if a distance sensor is used, the screen edge position can be measured with high accuracy.
Further, it is possible to prevent the shift of the cutting position based on the screen edge position.
Further, it is not necessary to correct the position of the cutting means vertical axis 23 during cutting, and the control of the cutting unit 50 can be simplified.

In addition, since the fixing means 28 with the pressing mechanism is configured as described above, the dismantling device for the liquid crystal television can automatically fix the liquid crystal television and measure the screen edge position and the liquid crystal surface height. If the distance from the position to the cutting position and the depth of cut are registered in the control system, the dismantling worker's work is only to place the LCD TV on the mounting base 17, thus further reducing the dismantling worker's workload. I can do it.
Further, since cutting and disassembly can be performed with parts such as the legs of the liquid crystal television attached, there is no need to remove parts such as the legs of the liquid crystal television in advance, and the working time can be shortened.

  Further, in the liquid crystal television disassembling apparatus 300 according to the present embodiment, although not shown, the storage means for storing the movement amount of the side surface position adjusting unit 28b of the fixing means with pressing mechanism 28 and the external dimensions for each size of the liquid crystal television And a liquid crystal television registered in the registration means and a registration means for preliminarily registering the relationship between the liquid crystal screen dimensions and the liquid crystal screen dimensions obtained from the movement amount of the side surface position adjustment unit 28b stored in the storage means A judgment means for obtaining an approximate liquid crystal screen size by comparing the external dimensions of the distance measurement sensor 24 and a scanning control means for controlling the scanning of the distance measuring sensor 24 based on the liquid crystal screen dimension obtained by the judgment means may be provided.

  When the above-described means are added, the external dimensions of the liquid crystal television vary depending on the product, the size, and the year. However, the approximate amount of the liquid crystal screen in the liquid crystal television is determined based on the amount of movement of the side position adjustment unit 28b. Since the dimensions can be obtained, the scanning of the distance measuring sensor 24 is performed at high speed up to the vicinity of the screen end position of the liquid crystal television, and the detection time of the screen end position can be shortened by making details from the vicinity of the screen end position.

In the present embodiment, the distance measuring sensor 24 is attached to the moving means 25 and can continuously measure the height of the front panel surface and the height of the liquid crystal surface.
That is, when the distance measuring sensor 24 is scanned, there is a step due to the design shape on the front panel surface of the liquid crystal television, so the distance measuring sensor 24 detects the position of the step, but the liquid crystal surface is flat. The measured values of the height of 24 are almost the same.

Therefore, in the scanning from the outside to the inside of the liquid crystal television of the distance measuring sensor 24, when the measured value of the height of the distance measuring sensor 24 is constant over a predetermined distance in the scanning direction from the position where the distance measuring sensor 24 has changed rapidly, It is possible to detect the position where the measured value of A changes rapidly as the screen edge position.
When the distance measuring sensor 24 is scanned from the top of the liquid crystal screen to the outside, the position at which the height measurement value suddenly changed first is the screen end position. Therefore, the screen end position can be determined by simple control regardless of the design shape of the liquid crystal television. It can be detected.
In the present embodiment, the distance measuring sensor 24 is attached to the moving means 25. However, the distance measuring sensor 24 may be installed above one surface of the mounting base 17 and the mounting base 17 may be moved. .
