2. Description of the Related Art In a conventional apparatus, a device to be measured is manually carried into a sensitivity measuring box, and after sensitivity measurement, it is manually carried out to classify it into a good product and a defective product, and conveys the good product to the next step.

[0003]

In the above-mentioned conventional example, the workability is poor because measurement is carried out manually into and out of the sensitivity measurement box of the device under test and whether the product is good or defective. There is a problem that it takes time and hinders automation of the production line.

[0004]

In order to solve the above-mentioned problems, the apparatus of the present invention carries in the device to be measured 1 into a plurality of sensitivity measurement boxes 2A to 2C installed vertically as shown in FIG.
In the sensitivity measuring device which is carried out after the sensitivity measurement, the sensitivity measuring boxes 2A to 2C are put out, and the entrances 3A to 3C, 4A are put out.
To 4C are provided, and the exits and entrances 3A of the boxes 2A to 2C are provided.
~ 3C, 4A ~ 4C to communicate with the internal conveyor 5A ~ 5C
Is installed, and exits, exits, and entrance-side lifters 6 and 7 are arranged, and a loader conveyor 8 that feeds the device under test 1 and an unloader conveyor 9 that takes out the DUT 1 are provided to the entrance-side and exit-side lifters 7 and 6, respectively. It is characterized by

[0005]

1 is a side view showing an embodiment of the device of the present invention. In FIG. 1, 10 is a box mount, 2A to 2C are three sensitivity measurement boxes installed vertically on this mount 10, 3A to 3C are outlets provided in the boxes 2A to 2C, 4A to 4C are also inlets, 11A. ~ 11C
Is an exit side tunnel portion, and 12A to 12C are entrance side tunnel portions. Exit of each box 2A-2C, entrance side tunnel parts 11A-11C, 12A-12C and exit, entrance 3A-
3C, 4A to 4C are communicated with each other, and internal conveyors 5A to 5C are inserted, and exits, entrances, and entrance side lifters 6 and 7 are arranged, and the entrance and exit side lifters 7 and 6 are respectively covered. A loader conveyor 8 for feeding the measuring machine 1 and an unloader conveyor 9 for taking out the measuring machine 1 are provided. Reference numeral 9A is an unloader conveyor for picking out a good product, 9B is an unloader conveyor for picking out a defective product, and 6A and 7A are elevators with a conveyor.

The device under test 1 is placed on the loader conveyor 8,
The to-be-measured device 1 is detected by a loader side sensor (not shown), the loader conveyor 8 is driven, and it is transferred to the conveyor on the elevator-mounted platform 7A of the inlet side lifter 7. The lift 7A moves to the positions of the boxes 2A to 2C. Depending on the number of vehicles produced per day, for example, if 250 units / day, the first stage, 5
The units to be measured 1 are distributed to the boxes on the first and second stages for 00 units / day, and on the first to third stages for 750 units / day by the lifting platform 7A. The device 1 to be measured is transferred from the lifting platform 7A onto the internal conveyors 5A to 5C, is carried into the boxes 2A to 2C through the entrance side tunnel portions 12A to 12C, and the device 1 to be measured is placed at the center of the box to detect the device 1 to be measured in the box ( (Not shown),
After the internal conveyors 5A to 5C are stopped and the sensitivity is automatically measured, the measured equipment 1 is moved to the positions of the boxes 2A to 2C by the internal conveyors 5A to 5C. Transfer to conveyor. As a result of the sensitivity measurement, the device under test 1 determined to be non-defective is placed on the unloader conveyor 9A for non-defective product from the conveyor of the lift 6A, and the device under test 1 determined to be non-defective is placed on the unloader conveyor 9B for defective product. Be transferred. Non-defective products are automatically transported to the next process.

FIG. 2 is a block diagram of a quality determination device for a device under test using the device of the present invention. The high-frequency signal output from the standard signal generator 13 in which the sensitivity standard value of the device under test 1 is set is input to each of the boxes 2A to 2C, and the device under test 1 receives the high-frequency signal within a fixed time by the data from the encoder 14. Then, the device under test 1 makes a sound, and this sound is converted into an electric signal by the microphone 15 mounted in the boxes 2A to 2C, and this electric signal is input to the controller 17 via the interface 16. Since the electric signal can be received and the electric signal is input to the controller 17 and detected, the device under test 1 is determined to be non-defective. If the device under test 1 does not sound within a certain period of time and an electric signal cannot be detected, it is determined as a defective product. The controller 17 controls the entire measurement system.

[0008]

As described above, according to the present invention, it is possible to automatically measure the sensitivity by allocating the device to be measured to a plurality of sensitivity measuring boxes, and then take it out. Not only can sensitivity measurement be performed automatically, and a large amount of measurement can be performed at once, which not only improves workability, but also
There is no danger of affecting the automation of the production line.
