Description

[Detailed description of the invention] Industrial application field This invention can be applied to electronic parts and devices at various temperatures.
The present invention relates to an information transmission device for externally transmitting test results of a rotary drive type environmental test device that tests reliability in a humid environment.

BACKGROUND TECHNOLOGY As an information transmission means of a conventional rotary drive type environmental test device, a rotary drive type environmental test device rotatably supported on a bearing 3 in an environmental test chamber 1 connected to a constant temperature air supply device via an air circulation flow path 2 is used. The drive shaft 4 is composed of a drive shaft 4, a drum 10 fixed to the drive shaft 4 so as to rotate in synchronization with the rotary drive shaft 4, and a test object mounting plate 11 mounted on the drum 10. In an environmental test device that is driven continuously or intermittently via a power transmission means, a tester mounting board 6 is fixed to a portion of the rotary drive shaft 4 that projects outside,
It is known that a test module 7 is mounted on the mounting board 6 and the results are displayed by a signal 15 provided on the test object mounting body 11.

However, in such conventional environmental test equipment, the test results are displayed on the mounting plate of the test object, so the operator cannot know the test results of all the test objects in the environmental test equipment. It was not possible to tell whether the test object was good or bad until the test object came to the attachment/detachment section. Furthermore, there was no means for transmitting data regarding the acceptability or defectiveness of the test object to a control means such as an industrial robot located outside the environmental testing apparatus. For this reason, there were disadvantages such as the inability to automate the mounting and dismounting of test objects and the selection of good and defective products using industrial robots.

Problems to be solved by the invention Conventional rotary-driven environmental test equipment has been in use, and it is desirable to develop equipment that can automate the loading and unloading of test objects and the selection of good and defective products using industrial robots. It was rare.

Therefore, the inventors of this invention thought that in order to automate the attachment/detachment and sorting of test objects, it would be a good idea to send the inspection results of the test objects to the industrial robot in advance as information to the outside. It was devised to provide a means of communication.

Means for Solving the Problem In other words, the present invention includes a test module connected via a cord to a socket for energization testing of each test object of a rotary drive type environmental test device, and a test module that connects the test object to the test module. When the inspection of the test object is completed, the test result is stored, and the test result is transmitted via the oscillator installed in the drive shaft, and if the test has not been completed, the energization test is performed again. An information transmission device for a rotary drive type environmental testing device, characterized in that the oscillator is configured to transmit information to a receiver using light or electromagnetic force, The above objectives were achieved.

Function: Therefore, when the device according to the present invention is used, a computer instructs the test module to perform an electrical conduction test or the like on a test object in a predetermined environmental condition in the environmental testing device, and the results are sent to the test object. The result of the current test is recorded whether it was good or bad. Similarly, the above-mentioned test is performed on the test object connected to each socket, and the results are recorded in the computer along with a number identifying the test object.

When the current test is completed for the test object, the number of the test object and the inspection results recorded in the computer, whether the test object is good or bad, are converted into optical or electromagnetic signals by an oscillator and transmitted to a receiver. sent to.

Therefore, when the receiver is connected to an industrial robot that attaches and detaches a test object to this environmental test device, the results of the energization test of the test object can be input into the industrial robot in advance. In that case, it becomes possible to automate the selection of test objects.

Embodiments The present invention will be described in detail below with reference to embodiments shown in the drawings.

Figure 1 is a cross-sectional view showing the information transmission device installed in the rotary drive type environmental test equipment, and shows the information transmission device installed in the environmental test chamber 1.
is connected by an air circulation passage 2 to a constant temperature air supply device (not shown). Inside environmental test chamber 1,
A rotary drive shaft 4 is rotatably supported by the bearing 3, and the rotary drive shaft 4 is connected to a drive motor 5 via a power transmission means such as a chain. In addition, a rotary drive shaft 4 protruding outside the test chamber 1
A tester mounting board 6 that rotates together with the drive shaft 4 is fixed to the tester mounting board 6, and a test module 7 and a control computer 8 that controls the operation of the test module 7 are mounted on the tester mounting board 6. , an oscillator 9 is mounted on the drive shaft 4 for transmitting information to the outside.

On the outside of the drive shaft 4 in the test chamber 1, a substantially cylindrical drum 10 is mounted on the drive shaft 4 coaxially with the shaft so as to rotate together with the shaft. Further, on the outer surface of the drum 10, a plurality of mounting plates 11 for mounting test objects such as electronic components are radially provided. 12 is a socket for connecting the test object, and this socket 12 is connected to the rotational drive shaft 4.
are connected to the test module 7 through the openings 13 of the test modules 7, respectively. The inspection module 7 and the like are electrically connected to the outside via sliding contacts.

Electrical connections with the test module 7, control computer 8, and oscillator 9 mounted on the tester mounting board 6 and the socket 12 mounted on the mounting plate 11 of the test object are made as shown in FIG. Each socket st _l to st _o for carrying out the current test of the test object
and an inspection module 7 are connected, and the inspection module 7 and a computer 8 are further connected. The output section of the computer 8 is connected to an oscillator 9 that converts the digital signal into an optical signal, and a receiver 14 that converts the optical signal into a digital signal is provided at a position facing the oscillator 9 in the light oscillation direction. .

Next, the function of the computer 8 is to instruct the test module 7 to conduct a power test on the sockets 12 st _l to _{st o} , as shown in FIG. Record in memory. When the inspection of the socket is completed, the recorded number of the test object and data regarding pass/fail are output to the oscillator 9. Then, after confirming whether a new test object has been attached to the socket, the system is shut down when the test is finished, and when a new test object is installed, it returns to the beginning and turns on the power. Have them do the test.

In this embodiment, an optical communication method is used as a means of communication between the oscillator and the receiver, but the method is not limited to this. Multiple solenoids are provided outside the drive shaft as oscillators, and It may also be configured using an electromagnetic force with a limit switch attached to a fixed part at the position where the limit switch is attached.

Effects of the invention As mentioned above, since the conventional device is a rotary drive type, it was not possible to transmit information on whether it is good or bad to the outside, but the device according to the present invention has an information transmission means on the extension of the shaft. Since the data is not affected by the rotation of the drive shaft and is transmitted to the outside using communication means such as optical communication means, industrial robots can be used to attach and detach test objects and to screen out defective products. This makes it possible to automate environmental testing equipment.
