Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic adjustment test apparatus for performing automatic adjustment and automatic test of various electronic devices such as electronic measuring instruments.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional general adjustment test line. The adjustment test line performs various adjustment tests such as vibration test, operation test, adjustment value setting, equipment stability test,
It is composed of a plurality of stations 10 that stop the flow of equipment and a carrier 11 that conveys equipment between the stations. When performing the adjustment test in series in this way, the adjustment test time at each station is usually not the same, so the UUT stays in front of the station with the long adjustment test time and the overall flow is constant. No, some stations have idle time. Further, since the station is fixed, it is not easy to change the adjustment test sequence, and if different types of devices under test are mixed, the manual adjustment test may be erroneous.

[0003]

In the adjustment test line for performing the adjustment test in series as described above, the whole flow is restricted by the station which takes a relatively long time, and the change after the stroke is easy. There is a drawback that cannot be done. It is an object of the present invention to realize an efficient automatic adjustment test apparatus that eliminates the stagnation of the entire flow due to a time-consuming adjustment test station and can freely change the end of the stroke.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the overall construction of the automatic adjustment test apparatus of the present invention. The automatic adjustment test apparatus is a computer system 100 including a central control unit (CPU), a terminal, a disk, a floppy disk, and a printer, which controls the entire apparatus, and an automatic adjustment test storage 200 including a plurality of stations 201. And a carrier control means 301 for controlling the movement of the carrier 205 between the stations, and a device under test control means 3 for controlling the device under test to perform an automatic adjustment test.
02, a control unit 300 including a test device control unit 303 for controlling the operation of a test device such as a vibration tester.

FIG. 2 shows the structure of the automatic adjustment test storage cabinet 200. In the automatic adjustment test storage 200, the device under test 20 mounted on the pallet 210 is loaded from the device loading table 202, and is moved vertically and horizontally to rotate to the target station 2.
The pallet 210 is moved to 01, and the equipment under test for which the adjustment test has been completed is sorted into a good product and a defective product, and the carrier 205 that moves to the good product carry-out table 203 and the bad product carry-out table 204 rotates vertically and horizontally. It's in the center so you can. A plurality of stations 201 are arranged on both sides of the carrier, and a plurality of stations 201 are arranged in the vertical direction. Each station 201 has a device adjustment test station panel 221 for adjusting the device under test 20, a device adjustment test station panel 221 for testing the device under test 20, and a vibration tester. There are those equipped with test equipment such as, those that have a constant temperature for a stable time before the test, and those that are stored for the waiting time of the test.

As shown in FIG. 3, the device under test 20 is placed on a standardized pallet 210, a power source supplied from the back side of the pallet 210, and an RS2 on the panel 211.
It is connected to an equipment under test I / O interface pad 212 that can be used as an I / O interface such as 32C or GPIB, and a female measuring pin 213 that supplies a standard voltage or outputs an output voltage. Further, a bar code 214 is attached to the front surface of the pallet, so that a plurality of models can be distinguished and an adjustment test can be performed.

The station 201 for the adjustment test has a panel as shown in FIG.
Set on the pallet 210, the I / O interface pad 212 of the panel 211 on the pallet 210 is connected to the I / O interface elastic contact 222 of the panel 221 of the device adjustment test station and the female measurement on the panel 211 of the pallet 210. The pin 213 is electrically connected to the male measuring pin 223 on the panel 221 of the instrument conditioning test station.

The adjustment test of the device under test 20 is performed as follows. The device under test 20 is placed on the pallet 210, and the power supply, the I / O interface, and the measurement pins are connected via the connector. A bar code 214 indicating the device under test 20 is set at a designated position on the pallet 210. The pallet 210 on which the device under test 20 is placed is placed on the device loading table 202. Up to this point, human operation is required, but after that, it is automatically performed. Transfer the pallet 210 on the equipment loading table 202 to the carrier 2
05 is moved into the automatic adjustment test storage 200. At this time, the bar code 214 on the pallet 210 is read at the carry-in port, and the adjustment inspection of the device under test 20 on the pallet is performed according to the model. The carrier 205 moves the pallet 210 to an unused preheating station before adjustment and pushes it into the station. When all the target adjustment test stations are used, another test is performed, for example, the pallet is pushed into a station equipped with a vibration tester and the vibration test is performed first. When the required residual heat is completed, the carrier 205 moves the pallet 210 to the adjusting station and pushes it into the adjusting station. The adjustment station has a panel 221 of the device adjustment test station, which makes contact with the I / O interface elastic contactor 222 and the male measuring pin 223 for inputting / outputting a reference voltage and an output voltage, for example. The device under test 20 is automatically adjusted, and the device under test 20 is adjusted.
Set the adjustment value in the internal memory. When the adjustment is completed, the carrier 205 moves to a test station that has not been executed yet, and the test is performed. When all the remaining test stations are in use, the pallet 210 is pushed into the storage station by the carrier 205 and stored. When all adjustment tests have been completed, the equipment delivery table is
Defective products are distinguished and conveyed by the conveyor 205. The content of the defect is output to a terminal or printer of the computer system 100 and used as data for repair.

[0012]

The present invention is configured as described above,
By appropriately increasing or decreasing the number of stations having the required functions, the storage time can be shortened and the adjustment test time can be shortened. The order of the adjustment test can be freely changed each time, and the unused adjustment test station is preferentially used. After setting the device under test on the pallet and installing it on the device loading table, it is completely unmanned, and it is possible to mix the types of devices to be adjusted and tested, and overall there is a high degree of freedom and efficient automatic adjustment. The test equipment is realized.
