Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport jig that can automatically feed a hybrid integrated circuit to an adjustment device or an inspection device.

In a hybrid integrated circuit, necessary electronic components are mounted on a ceramic substrate, and then lead terminals for connection to other circuit boards are attached to one or two sides of the substrate. The hybrid integrated circuits with lead terminals attached are then stored in a special transport box and transported to the adjustment or inspection process, where they are connected and disconnected one by one to the connector connected to the adjustment or inspection device. adjusted or inspected.

When attaching and detaching lead terminals of hybrid integrated circuits to connectors, it is difficult to automate the attachment and detachment because the mechanical bonding strength between the ceramic substrate and the lead terminals is weak, and the lead terminals are thin and weak. , they had to be attached and detached one by one by hand.

For this reason, a worker is always present at the adjustment device or inspection device to attach or detach the hybrid integrated circuit.

For example, if the time required to attach and detach hybrid integrated circuits is 5 to 6 seconds per piece, and the time required for adjustment or inspection to be 5 to 6 seconds per piece, half of the worker's work time will be spent waiting. becomes. Furthermore, as the time for adjustments, inspections, etc. becomes longer, waiting time increases and work efficiency decreases.

Furthermore, as described above, the lead terminals of the hybrid integrated circuit are soft and weak, so sufficient care must be taken in handling them, making it difficult to automatically supply them to an adjustment device or a testing device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transport jig that eliminates the above-mentioned drawbacks of the prior art, efficiently attaches and detaches hybrid integrated circuits, and automates the supply to an adjustment device or inspection device.

In order to achieve the above object, in the present invention,
A connector is placed on the board as a transport jig, and the hybrid integrated circuit is inserted into this connector, and the electrical connection between the hybrid integrated circuit and the adjustment device or inspection device is made from the bottom of the board via the contact pins of the connector. The feature is that the connection is made as follows.

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the transport jig according to the present invention. In the figures, the transport jig 1 is composed of a board 2 and a connector 7 fixed to the board 2. has been done. The substrate 2 includes:
A hole 3 for positioning, a hole 4 for accommodating a connector 7, and a through hole 5 penetrating the board 2 from the bottom of the hole 4 are formed, the lower part of which becomes a tapered hole 6 that widens downward. There is. Contact pins 8 are implanted in the connector 7 at predetermined intervals. The contact pin 8 is fitted into the through hole 5 such that its lower end projects into the tapered hole 6.

An example of an inspection apparatus using such a transport jig 1 is shown in FIGS. 3 and 4.

In the figure, the inspection device 10 includes a cable 11
The test board 12 is connected by. This test board 12 includes electronic components 13 necessary for testing,
A blade 15 is attached via a strut 14. Between the inspection board 12 and the blade 15,
A guide pin 16 is provided upright. A probe pin 17 is slidably supported by the guide pin 16 and is urged by a spring 18 so as to protrude upward. Note that the guide pins 16 and probe pins 17 are formed in the same arrangement as the through holes 5 of the transport jig 1. The conveyance means including the rails 19 forming the conveyance path of the conveyance jig 1 includes a stopper (not shown) that fits into the hole 3 of the conveyance jig 1 in order to position the conveyance jig 1 at the inspection position. ing. Lead terminals 21 are attached to the hybrid integrated circuit 20 .

In the above configuration, the hybrid integrated circuit 20 is inserted into the connector 7 of the transport jig 1 all at once between the assembly process and the inspection process. Therefore, the insertion and attachment can be performed continuously regardless of the time required for adjustment, inspection, etc., thereby eliminating waiting time and improving work efficiency.

The transport jig 1 containing the hybrid integrated circuit 20 is stored in a magazine of a transport means and supplied to the transport means. The transport means takes out the transport jig from the magazine and sends it along the rail 19 to the inspection device. When the transport jig 1 reaches above the test substrate 12, the stopper is activated and fits into the hole 3 to position and stop the transport jig 1. Then, the test board 1
2 is raised by a lifting means (not shown),
The probe pin 17 is inserted into the tapered hole 6 of the transport jig 1. Then, the probe pin 17 comes into contact with the contact pin 8 of the connector 7 protruding into the tapered hole 6, and an electrical connection is established. In this state, the testing device 10 operates and tests the hybrid integrated circuit 20. When the inspection is finished, the test board 12 is lowered and the probe pins 17 are removed from the transport jig 1, the stoppers are removed from the holes 3 and the transport jig 1 is transported.

In this way, automatic feeding of hybrid integrated circuits to inspection equipment etc. can be made possible, adjustment,
It is possible to automate inspection work.

As described above, according to the present invention, the connector is mounted and fixed on the substrate, and the hybrid integrated circuit is attached to and detached from the transfer jig in which the contact pins of the connector protrude into the tapered holes formed in the substrate. After assembly, the hybrid integrated circuit can be attached and detached all at once, which prevents waiting time and improves work efficiency. Furthermore, after the hybrid integrated circuit is inserted into the transport jig, it can be handled regardless of the mechanical strength of the lead terminals of the hybrid integrated circuit, which facilitates automation.
