The utility model aims at providing a testing arrangement for detecting PCB board input/output logic can be quick accurate the completion to the plug winding displacement of photoelectric control board.

Therefore, the test device for detecting the input and output logic of the PCB comprises a test platform, a driving device and a plurality of sliders, wherein at least one positioning part used for fixing the external PCB is arranged on the test platform, the sliders and the PCB are consistent in number and in one-to-one correspondence, the row pins are L-shaped row pins, one end of each row pin is vertically inserted and soldered on a contact of the PCB, the other end of each row pin extends out of the PCB in a manner of being parallel to the PCB at the edge of the PCB, each slider is fixedly provided with a wire row used for inserting the row pins, the wire row is electrically connected with a controller and/or a display of the test device, and the driving device is used for driving the wire row on each slider to be horizontally close to or far away from the corresponding row pins.

Further, the driving device is embodied as one or more of a motor and a cylinder.

Further, each line row is electrically connected with the controller respectively.

Furthermore, the line bank comprises an input line bank for inserting an input pin bank in the pin bank and an output line bank for inserting an output pin bank in the pin bank, the input line bank is electrically connected with the controller, and the output line bank is electrically connected with the display.

Further, the output line rows are electrically connected with the controller.

Furthermore, location portion specifically is a plurality of reference columns along PCB board periphery setting, and each reference column distributes around the PCB board in order to be spacing with the PCB board in the horizontal direction, and each reference column is not located the stroke direction of each slider.

Has the advantages that:

the driving device drives the sliding block to be close to the input and output pin header, so that the fixed wire row on the sliding block is inserted into the input and output pin header, when the operation is finished, the driving device drives the sliding block to be away from the input and output pin header, the wire row is automatically extracted from the pin header, and the testing device automatically finishes inserting and extracting the wire row to the photoelectric control panel, so that the efficiency is higher, and the risk of bending the pin header due to the fact that the wire row is inserted unevenly is avoided.

The above description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the present invention is given.
