BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detaching device for separating and disassembling an electronic device having a display device, and more particularly to a detaching device of a display device for detaching a display device such as a cathode ray tube from a mounting frame. is there.

[0002]

2. Description of the Related Art Electronic equipment, for example, a television set having a cathode ray tube as a display device has a structure as shown in FIG. The television set 701 includes a cathode ray tube (CRT,
A cathode ray tube) 200 and other circuit boards and the like are arranged. The cathode ray tube 200 has a panel portion 210 made of a substantially transparent glass material and a funnel portion 211 made of a glass material mixed with lead. The panel portion 210 and the funnel portion 211 are frit glass (solder glass). Are welded together to form an annular shape.

In such a cathode ray tube 200, a metal explosion-proof band 705, a panel portion 210 and a funnel portion 21 are provided.
The cathode ray tube 200 is attached with the outer periphery of the cathode ray tube 200 being clamped. The cathode ray tube 200 includes the metal fittings 11 a for holding the explosion-proof band 705.
11d is held against the fixing seat 707 on the inside of the front of the cabinet 702 and attached by screws 704. By the way, in recent years, as the shortage of disposal sites for waste materials has been exclaimed, and as the age of reuse progresses without producing waste materials,
There is an increasing demand to reuse the waste materials of used television sets. Since the panel portion 210 and the funnel portion 211 of the cathode ray tube 200 are made of glass, they are relatively easy to reuse. For this reason, when recycling the cathode ray tube, it is necessary for an operator to remove the cathode ray tube, which is easily regenerated, from the explosion-proof band 705 which is the mounting frame as described above.

As described above, when the glass portion of the cathode ray tube of a used or failed television set is reused, the cathode ray tube is an explosion-proof band 705 which is a mounting frame.
Although it is necessary to remove the cathode ray tube from the conventional method, there are the following methods for the operator to remove the cathode ray tube. The cathode is attached to the metal-made mounting frame by directly applying electric power to the mounting frame through this conductor, and the mounting frame is heated and expanded to provide a gap to mount the cathode ray tube. There is a method that can be removed. However, in this method, the heating effect of the mounting frame varies depending on the contact state of the conductor (power feeding portion) that is in contact with the mounting frame, so that there is a problem that the heat treatment work is difficult to manage.

[0005]

However, in such a removing method by energizing, when the conductor is brought into contact with the mounting frame and the contact portion of the mounting frame is dirty, the conductor is inserted into the mounting frame. Therefore, there is a problem that a predetermined current cannot be stably supplied, and moreover, the contacts of the conductor are melted by the discharge and welded to the mounting frame. Therefore, it is very troublesome because the operator needs to polish the abutting portion of the mounting frame before the conductor comes into contact with the mounting frame to energize. Further, although there are various sizes of cathode ray tubes, there is a problem in that it is difficult to remove such various types of cathode ray tubes from the cabinet and the mounting frame. By simply automating the separation and disassembly of the cathode ray tube and the mounting frame, which is normally done by the operator, the operator can judge the cathode ray tube, the mounting frame and the cabinet of various models, and separate them according to their size. It is necessary to carry out a treatment, and if the cathode ray tube, the mounting frame and the cabinet are not positioned at that time, it cannot be separated and disassembled well, and the separation and disassembly takes a long time. Even when the operator confirms and holds the removed cathode ray tube with eyes, if the size of the cathode ray tube is different, it is not possible to reliably hold the cathode ray tube, and the cathode ray tube is removed when removing the cathode ray tube from the mounting frame. There is a risk of breaking the pipe. In the separation and dismantling work of the cathode ray tube, the mounting frame, and the cabinet, the worker may harm his or her body due to the influence of dust or noise.Therefore, dust-proofing and sound-proofing equipment must be used. The efficiency of removing the cathode ray tube is poor.
Therefore, the present invention has been made to solve the above problem, and the display device can be easily and reliably removed from the mounting frame for mounting the display device to the device body, and the mounting frame and the display device can be separately discharged. An object is to provide a device for removing a display device.

[0006]

According to the present invention, the above object is a device for removing a display device from a mounting frame for mounting the display device on the main body of the device. Heating means for heating and expanding the
By a display device removing device including a display device pressing means for pressing the display device away from the mounting frame to remove the display device from the mounting frame, and a discharging means for separately discharging the mounting frame and the display device, To be achieved. According to the present invention, when the display device is removed from the mounting frame for mounting the display device to the device body, the heating means heats the mounting frame to expand it. The display device pressing means pushes the display device away from the mounting frame to remove the display device from the mounting frame. Then, the discharging means separately discharges the mounting frame and the display device.

Next, the operation of the device for removing the above-mentioned display device will be described. The cathode ray tube supply unit SP of FIG. 1 contains, for example, a large number of used cathode ray tubes 200, and by opening the door 51a of the chamber 551 from this supply unit SP to the conveying means 700 side, each cathode ray tube 200 is opened. Tube 2
00 is loaded on the holding table PA. In this case, the cathode ray tube 200 is integrated with the mounting frame, but the cabinet (device body) has already been removed from the mounting frame. Therefore, the cathode ray tube 200 and the mounting frame 23
Only 0 is installed on the holding table PA. As shown in FIG. 2, the installation state is achieved by placing the four holding fittings 11a to 11d of the mounting frame 230 on the receiving members 59a of the four columns 59 of the holding table PA. At this time, the elastic supporting means 520, 520 is only in contact with the funnel portion 211 of the cathode ray tube 200. Therefore, the cathode ray tube 200

As shown in FIG. 1, the holding table PA is a cathode ray tube 2.
00 is placed on the chamber 551 by the transfer means 700.
It is transported inside. Then, the transport means 700 positions the holding table PA at the clean position PL1. Then, Figure 1
As shown in FIG. 3 and FIG. 3, the first arm 151 of the first robot RT1 moves the camera 110 of the size detecting means 190 to photograph the holding metal fittings 11a to 11d of the mounting frame 230, and based on this information. The central processing unit 101 includes the first arm 15 of the robot RT1 obtained from the control unit 100.
From the information of the position of 1, X of four holding metal fittings 11a to 11d
The position in the direction coordinate and the Y direction coordinate is calculated. As a result, the control unit 100 causes the cathode-ray tube 2 on the holding table PA to move.
Check the size of 00.

Next, the control unit 100 controls the robot RT1 based on the size information of the cathode ray tube 200 to position the wire brush 121 of the first arm 151 above the holding metal fitting 11a. . And the control unit 1
00 operates the motor 122 to rotate the wire brush 121 continuously, and the control unit 100 operates the actuator 152 to lower the wire brush 121 to hold the metal fitting 11a.
Abut. As a result, the upper surface of the holding fitting 11a is polished and cleaned by the wire brush 121. That is, since the upper surface of the holding metal fitting 11a is an energized surface performed by the heating means 250 of FIG. 3, this energized surface is cleaned. Since the polishing dust generated at this time is collected by the dust collector 60 via the cylindrical body 131a, it does not scatter to the peripheral portion of FIG.
Then, similarly to the holding metal fitting 11a, the upper surface of the other holding metal fitting 11c is also cleaned by polishing with the wire brush 121.

Next, at the heating position PL2 corresponding to the heating means 250 shown in FIGS. 1 and 3, the carrying means 700 holds the holding table P.

2a is positioned at the heating position PL2. When the actuator 252 operates, the operation unit 260 descends in the arrow Z direction. At this time, the two conductors 221a of the operation unit 260,
Reference numeral 221b corresponds to the holding fittings 11a and 11c, respectively, and the conductor 221a is the holding fitting 11a that has been polished.
Abut on the upper surface (current carrying surface) of the
The other conductor 221b is the holding metal member 11 that has been polished.
The upper surface (current-carrying surface) of c is contacted with a predetermined pressure. Then, the power supply unit 80 operates according to a command from the control unit 100 to supply power to the two conductors 221a and 221b. As a result, the power supply unit 80 supplies a predetermined amount of power to the mounting frame 230, so that the temperature of the mounting frame 230 made of metal rises and expands. Therefore, a small gap is generated between the mounting frame 230 and the periphery of the side surface of the cathode ray tube 200, and in this state, the cathode ray tube 200 and the mounting frame 230 are separable. When the pulse motor 226 of the operation unit 260 is operated, the feed screw 223 rotates and the conductors 221a and 221b can move along the direction toward or away from each other.
Even if the type of 00 is different, the conductor 221 is attached to the holding metal fittings 11a and 11c of the mounting frame 230 of the cathode ray tube 200.
The a and 221b can be reliably brought into contact with each other. Moreover, since the holding metal fittings 11a and 11c have already been cleaned, there is no unnecessary adhered matter, and the electric power can be surely directly supplied to the mounting frame 230.

Next, the holding table PA is placed at the heating position PL shown in FIG.

In the above-described embodiment, 0 uses the power supply unit 80 that flows a large current with a small voltage of a commercial frequency, but the present invention is not limited to this. For example, high frequency induction power that induces an appropriate high frequency high frequency power. Sources can also be used. In this case, the inductor is arranged close to the mounting frame 230, but the inductor is arranged with a predetermined slight gap with respect to the mounting frame 230. By doing so, the mounting frame 230 receives the magnetic flux from the inductor, and the current generated inside the mounting frame 230 and the mounting frame 230
Self-heating occurs depending on the resistance value of the material. Therefore, the mounting frame 230 expands due to the temperature rise, and the mounting frame 230
Creates a gap between the cathode side of the cathode ray tube 200 and the periphery thereof. When using the high frequency induction power supply unit, cleaning means is not always required. In that case, if necessary, to prevent the cathode ray tube from receiving radiant heat from the mounting frame,
It is also conceivable to cool the cathode ray tube by injecting cooling air into the cathode ray tube, for example.

Further, the size detecting means 190 of FIG. 2 is provided corresponding to the cleaning means 100 in the embodiment of the present invention, but not limited to this, the size detecting means 190 is provided separately from the cleaning means 100. Of course, it is also possible to arrange it in the front part. The cleaning means 100 does not necessarily have to be provided in the chamber 551 of FIG. In the embodiment of FIG. 1, two robots RT1 and RT2 are used, and one robot RT1 has a cleaning means 100 and a heating means 25.
0 is operated, and the other robot RT2 is operating the display device pressing means 300 and the discharging means 600.
However, this is not the case, and the cleaning means 100 and the heating means 25
It is of course possible to use independent robots or control mechanisms for 0, the display device pressing means 300, and the discharging means 600.

Since the detaching device of the embodiment of the present invention operates as described above, the disassembly and disassembly of the cathode ray tube and the mounting frame can be performed very easily, safely and in a short time. Previously required multiple workers are monitoring the device itself 1
Since the name is sufficient, labor can be saved and work safety can be secured. And since the cathode ray tube is always held by the holding table,
The quality of the cathode ray tube can be secured by preventing accidents such as the cathode ray tube itself breaking. In addition, although the cathode ray tube is taken as an example of the display device in the above-described embodiments, the present invention is not limited to this, and the present invention is of course applicable to the case where a metal mounting frame is removed from another type of display device made of glass. Can be applied.
