Abstract

PURPOSE:To make continuous automation of environmental test possible by incorporating a quality testing stage of a specimen on a testing jig behind an environmental stage. CONSTITUTION:Specimens mounted on a testing jig are supplied to a conveyor 30 and stocked three dimensionally 7 by a conveyor 10 etc. When testing, a stocked specimens are sent to an environmental testing stage 1 by a conveyor 31 and a pusher etc. and exposed to heated air for thermal stress test. The specimens got out from the stage 1 are sent to an environmental testing stage 2 and exposed to cold air for cold stress test. Then, the specimens are sent to an environmental stage 3 and tested by exposing to dry air of normal temperature, and made to dry state of high temperature in a vacuum tank. Then, the specimens are preliminarily heated 6 and high temperature high humidity test is performed in an environmental testing stage 4. The specimens got out from the stage 4 are turned to the direction of a testing stage 13 by a carrying direction changer 15. The quality is examined in the stage 13 and stocked separately in a good quality goods stocker 20 or an inferior goods stocker 21.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is designed to sequentially transport a specimen by means of a cosive bear to a plurality of serial environmental test stages placed in different air conditioning conditions, and to It is a device that continuously and automatically performs environmental tests by exposing specimens to empty illumination problems one after another.In particular, the equipment is used to attach the specimen to an inspection jig and inspect its quality separately from the environmental test. The present invention relates to a continuous automatic environmental testing device in which the results are indicated as pass or fail with an indicator provided on the test jig, and therefore the test jig contributes to the convenience of selecting pass or fail of test samples.

Conventional Technology Conventionally, environmental testing by exposing specimens to air-conditioned atmospheres with different air conditioning conditions has relied on batch-type methods using multiple independent environmental test chambers, which has been inefficient. It was a target.

Problems to be Solved by the Invention Therefore, the present inventor arranged a required number of environmental test stages in a series with different air conditioning conditions, connected them by a conveyor, and tested the specimen. A study was carried out on sequentially transporting the test materials to the environmental test stages and continuously and automatically exposing them to the air-conditioned atmosphere at the stages, but in the process, the following problem was encountered.

In general, environmental tests on specimens mainly consist of a thermal stress test by exposing them to a high-temperature atmosphere and a cold stress test by exposing them to a low-temperature atmosphere. Cold stress during the stage has a negative effect on constant temperature maintenance.Moreover, since the specimens are carried from the preceding stage to the succeeding stage one after another, this poses a serious problem in terms of continuous environmental testing.

The present invention therefore seeks to ensure that continuous automation of environmental testing is achieved without such problems.

Means for Solving the Problems The apparatus for achieving the above object of the present invention is to attach a sample to an inspection case, inspect the quality of the sample apart from the environmental test, and use the test results to determine whether the sample is good or not. A continuous automatic environmental test device that indicates pass or fail using an indicator equipped with an inspection jig, which comprises at least two environmental test stages, a high-temperature ambient air exposure stage and a low-temperature atmosphere exposure stage, arranged in series. All of the environmental test stages were connected by means of a Kosibear that conveyed the above-mentioned specimen mounting inspection seat, and the specimen was mounted on the above-mentioned inspection jig by means of a Kosibear that could be raised and lowered on the starting end side of the serial line of the environmental test stage. A three-dimensional stocker with multiple stages of Koshibear that can carry out the delivered specimens by itself is connected, and the quality of the specimens on the inspection stage can be checked in a manner similar to the series of environmental test stages mentioned above. It is characterized by incorporating an inspection stage for inspecting pass/fail after the last environmental test stage.

+ According to the Japanese invention, the sample is mounted on an inspection jig, carried to the multi-stage conveyor of the three-dimensional stocker by a conveyor that can be raised and lowered, and is stocked in the three-dimensional stocker. The installation of this three-dimensional stocker prepares the sample for environmental testing.
It is possible to store a large number of stocks and carry them out one after another when necessary using the self-carrying ability, and to efficiently submit them to environmental tests.

The sample with the inspection jig carried out from the above stocker (
The sample (hereinafter abbreviated as "specimen") is conveyed to the first environmental test stage in the serial line of environmental test stages via suitable means, such as the above-mentioned liftable conveyor and traverser, and then subjected to different air conditioning. passed by a conveyor through each subsequent environmental test stage in which it is exposed to the conditioned atmosphere at each stage;
Required environmental tests will be conducted.

In this multi-stage environmental test, an appropriate stage of the above-mentioned three-dimensional stocker, for example, the top stage conveyor, is left open, and the sample that has undergone the previous environmental test is transferred to it.
A transfer system can be used in which the specimen is left at an appropriate temperature (generally room temperature) and then transported to the next environmental test stage. To prevent heat or cold absorbed by a specimen and an inspection jig in a stress test from being carried into a subsequent environmental stage, and to avoid adversely affecting the constant temperature maintenance of an air-conditioned atmosphere in the subsequent environmental test stage.

Transferring the sample taken out from the three-dimensional stocker to the next environmental test stage may be carried out by appropriate means, such as the above-mentioned liftable lift and traverser.

After completing the air-conditioned atmosphere test in the final environmental test stage, the specimen is then brought to the inspection stage, where a quality inspection other than the aforementioned environmental test is carried out, for example, if the specimen is an electrical device. Subjected to electrical conduction test inspection. Then, the test result is indicated as pass or fail by an indicator provided on the test piece to which the sample is attached. Therefore, application of the inspection jig is useful for conveniently selecting good and defective samples. In addition, this inspection stage is connected to the serial line of the environmental test stages after the last environmental test stage, in other words, it performs quality inspection on the specimens after each environmental test has been completed. It is reasonable to carry out environmental tests and quality inspections on That is, cold.

The quality inspection that follows is effective because it is preceded by a heat stress test.
