Description

Pneumatic test fixture

Technical Field

The utility model relates to an automatic test fixture, in particular to a pneumatic test fixture.

Background

Because the customer base plate needs to go the lamp of control through every button and turn on and turn off, and the lamp that every button corresponds is different, and the electric current that every lamp corresponds is also different, if through manual test, test speed is slow with the comprehensiveness of test not enough, the manual implementation is with high costs, so adopts the mode of preparation tool to test, and is fast like this, the rate of accuracy is high, cover comprehensiveness etc..

In summary, the utility model designs a pneumatic test fixture.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide the pneumatic test fixture, and aims to automatically test the key lighting fixture for the substrate, so that the test speed and accuracy are improved, the simplicity of manual operation is solved, the human factors are reduced, and the production efficiency, the shipment quality and the like are improved.

In order to achieve the above object, the present utility model is realized by the following technical scheme: the utility model provides a pneumatic test tool, including the handle, a support, the clamp plate, the district is placed to the base plate, tool frame and ampere meter, the middle part is placed the base plate in the tool frame, the base plate has been placed and has been placed the base plate in the district, the base plate top is provided with the clamp plate, the clamp plate passes through support and link mechanism and links to each other with the handle, the ampere meter sets up on the tool frame front panel, be provided with on the clamp plate with base plate contact complex probe, the probe links to each other with the PLC controller, be provided with down the trigger button on the PLC controller, it links to each other with the probe to push down the trigger button, the PLC controller still links to each other with solenoid valve controller and ampere meter, the ampere meter still links to each other with solenoid valve controller, solenoid valve controller links to each other with needle type pneumatic valve and the button press fit on the base plate. The substrate is also connected with the PLC controller through a photoresistor.

Preferably, the jig frame is connected to a power supply for supplying electricity.

The utility model has the beneficial effects that: the utility model has reasonable structural design, improves the testing speed and accuracy, solves the problem of simplicity of manual operation and reduces human factors, thereby improving the production efficiency, the shipment quality and the like and having strong practicability.
