[0011]

An embodiment of the present invention will be described below with reference to the drawings. Note that, for convenience, an electronic device is illustrated by an example of a television receiver.

(Embodiment) FIG. 1 is a block diagram of a concept of a processing apparatus of an electronic apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of a main part of FIG. 1, and FIG. FIG. 4 is a side view of the concept of the worktable, FIG. 4 is a plan view of FIG. 3, and FIG.

1 and 2, the television receiver 100 is mounted on a transport pallet 41, and is transported from left to right in the figure by a transport conveyor 40, for example, a chain conveyor stretched in parallel. First workbench 1
0 (left side in FIG. 1), the television receiver 100 is an automatic transfer device, for example, a belt conveyor driven in a direction perpendicular to the chain conveyor stretched in parallel from the conveyor 40. It is transferred together with the transport pallet 41 onto the tiltable first work table 10 by an apparatus or the like (not shown).

An operator is located in front of the tiltable worktable 10, and after confirming that the television receiver 100 has been transferred, a foot switch (not shown) is used.
A start signal is sent by pressing the key, and the work table 10 is inclined at a predetermined angle, for example, in a range of about 45 to 75 degrees.
The television receiver 100 mounted almost at the center of the worktable due to the inclination of the worktable 10 slides on the transport pallet and hits the stopper 2, and is located within a reach of the operator.

Here, the operator removes the back cover. After the work is completed, the transport pallet 41 on which the television receiver is mounted is returned to the transport conveyor 40 by the automatic transfer device again. The returned television receiver is transported by the conveyor to the cleaning device 20 in the next step.
It is carried in.

In the case of a small television receiver of about 14 inches to 20 inches, it is possible to work in a horizontal state without tilting the work table 10. In addition, even in the case of a large-sized one, the operator can arbitrarily set the inclination angle according to the model and the outer shape.

In FIG. 2, two work tables 10 are arranged before and after the cleaning device 20, respectively. The first reason is to allow a wide range of dismantling processing capabilities of the television receiver. That is, the number of personnel can be increased according to the processing amount.

The second reason is that when the next television receiver to be dismantled is transported while the disassembly work is being performed on one of the two adjacent work benches, the other work bench is disengaged. Allow to accept on top. That is, the time required for disassembly varies depending on the size and type of the television receiver. Therefore, it becomes a preliminary receiving place when it takes longer than a certain processing time. In this case, naturally, the worker moves to the next work table to perform the work.

Next, the structure of the tiltable worktable 10 will be described with reference to FIGS. 3 and 4, the worktable 10 includes a frame 1, conveyor belt conveyors 9 and 9 incorporated in the frame 1, a drive cylinder mounted on a lower surface of the frame 1, and a base frame 4. The conveyor belt conveyor is composed of two parallel belts, and conveys the conveyor pallet 41 near the stopper 2 and stops automatically. Frame 1 has bearing 5 and shaft 6
Thus, one end is hinged so as to be rotatable. The rod end member of the cylinder 7 is hinged to the other end side, and constitutes a link mechanism in which each fulcrum can rotate. When fluid pressure such as air or hydraulic pressure is supplied to the cylinder 7 by this configuration, the piston rod of the cylinder moves, and the frame 1 is inclined at a predetermined angle.

Incidentally, it goes without saying that the means for inclining the frame 1 may have any other structure than the above. For example, an eccentric disk may be attached to the motor shaft to tilt the plate. Further, the plate may be inclined by a cam mechanism or the like. (Either is not shown.) Next, the cleaning step will be described. The periphery of the television receiver mounted on the transport pallet 41 and transported to a predetermined position by the transport conveyor 40 is shut off in a substantially airtight state by the closed box 21 descending from above. Spray nozzle 2 near the ceiling of the closed box 21
2 and an exhaust duct 23 are provided.

Thereafter, high-pressure air is blown from a plurality of spray nozzles disposed near the ceiling toward the television receiver (air shower 24), and the CRT neck and D
Blows dust that adheres and accumulates on the Y and the funnel portion, the inner surface of the cabinet, the printed wiring board and wiring housed in the cabinet. Exhaust duct 23 at the same time as air jetting
Also actuate to inhale and discharge the soaring dust. The air ejection time was about 5 seconds to several tens of seconds.

After the cleaning, the closed box is raised, and the television receiver mounted on the transport pallet is sent to the next step by the transport conveyor 40. In the next step, the television receiver is again taken into the tiltable second workbench (right side in FIG. 1) together with the transport pallet,
The DY part (polarizing coil and neck printed circuit board, etc.) attached to the CRT neck part is removed. Note that D
In the step of removing the Y portion, since the inside of the television receiver is cleaned in advance, there is no dust soaring, and there is no adverse effect on the working environment and equipment.

After the DY section is removed, the CRT attached to the cabinet is again transported together with the transport pallet by the transport conveyor, to the next cabinet cutting step and the CRT.
It is sent to the removal process.

In the above embodiment, it is needless to say that the object to be pre-processed is not limited to video equipment (television receiver or display monitor, etc.) but may be any electronic equipment such as audio equipment and ear control.

[0025]

As described above, according to the pretreatment apparatus of the present invention, the removal of the back cover and the DY section, the removal of dust in the cabinet can be performed efficiently, and the dismantling work after the next step can be automated. In addition, the separate reproduction process after disassembly is facilitated. As a result, the recycling rate is improved, which contributes to environmental conservation and effective use of resources. In addition, the tiltable worktable can efficiently pre-process a wide variety of inch size and shaped television receivers.
