Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a sound system that completely blocks out sound, electromagnetic waves, etc. for inspection and adjustment of products in the middle of a production line, etc.
Concerning a room that is impermeable to electromagnetic waves, etc.

Conventionally, in the production of electrical products, as shown in Figure 1, each board and parts to which electronic parts such as resistors are attached are assembled, assembled,
Next, in the inspection and adjustment process (2), for example (1) In the case of a tape recorder with a radio, the electrical characteristics of the product are measured using airborne radio waves, sensitivity, noise measurements, etc. in an electromagnetic shield room, and the sound quality is checked in a soundproof room. , noise, mechanical noise,
After inspecting and adjusting the lighting condition on the front panel surface, the product was transported on a single conveyor to the next process (3), such as packaging and shipping.

These non-transparent rooms such as shielded rooms, soundproof rooms, and soundproof shielded rooms are designed to block external sounds, electromagnetic waves, etc. that would affect indoor inspections and adjustments; This prevents the sounds generated inside the room from flowing outside. Since a single long conveyor is used in the line, the impermeable chamber is generally installed in the middle of the conveyor, or is installed separately near the conveyor. . However, in the former case, if the conveyor is being driven during inspection adjustment in the opaque chamber, noise etc. will be generated, which is inconvenient.
It is not possible to stop the entire work flow by stopping the conveyor. Therefore, it is impossible to completely close the product entrance/exit with a closing plate (2). In the latter case, it is difficult to completely isolate the product from the outside by using a shielding member (9) with a large number of flexible strips of material. The closing plate at the loading/unloading entrance is closed and sealed, and the closing plate is opened to return the product onto the conveyor.Although it is possible to completely seal the door, the closing plate must be opened and closed for each task, which reduces work efficiency. However, the installation process requires a large area.
