The embodiment also discloses a PLC test method: taking the SIEMENS CPU SR40 and CPU SR20 as examples, the two PLCs have different lengths, the same width and slightly different PLC interface positions.
When placing PLC in equipment test assembly, after existence detection sensor 22 detects that PLC placed successfully, activity side flange 35 promoted one side of PLC, until promoting to fixed side flange 61, reserved slight clearance, PLC can slide in two side flanges, has accomplished PLC this moment and has slided in the X direction, and operation clamp plate 33 makes and presss from both sides tight cushion 34 and tip locating piece 23 fixed PLC jointly. Due to the fact that the lengths of the SR40 and the SR20 are different, after the clamping pressure plate 33 is clamped, the distance between the clamping pressure plate 33 and the end positioning block 23 is also different, the corresponding positions of the clamping detection bolts 49 on the clamping fixing plate are different, and one of the two sensors of the first clamping detection sensor 54 and the second clamping detection sensor 58 is triggered in an induction mode.
When the PLC is a CPU SR20 with a short length, the first clamping detection sensor 54 is triggered by the clamping detection bolt 49, and the long probe 39 and the short probe 41 at the output end extend out to be in contact with the output port of the PLC; an input end elongated probe 43 is in contact with the input port of the PLC.
When the detected PLC model is SIEMENS CPU SR40, the second clamping detection sensor 58 is triggered by the clamping detection bolt 49 due to the long length of the PLC, and the long output end probe 39 and the short output end probe 41 extend out to contact with the output port of the PLC; the transposition air cylinder 29 acts to drive the transposition sliding plate 27 to move to the corresponding PLC position, and after the first transposition detection sensor 55 is triggered (when the CPU SR20 is tested, the second transposition detection sensor 57 is triggered), the long probe 43 at the input end and the short probe 46 at the input end are all in contact with the input port of the PLC.

This example has anti-reversion measures: because the PLC can not be placed reversely up and down and can be placed reversely left and right when being placed, the characteristic that one side of the bottom of the PLC is a right angle and one side of the bottom of the PLC is an oblique angle is utilized, when the PLC is placed into a fixed position, if the PLC is placed reversely left and right, the right angle side of the PLC presses the travel switch pressing 42 strips, so that the pressing strip detection sensor 53 senses the PLC, and therefore the reverse placing error is judged.
Safety protection measures are as follows: because the metal probes of the two PLCs are electrified by 220V, in order to avoid damaging the PLCs and other dangers, when the PLCs are short-length PLCs, the clamping detection sensor I54 and the transposition detection sensor II 57 are required to sense at the same time, and the metal probes can be electrified; when the PLC is a long-length PLC, the clamping detection sensor II 58 and the transposition detection sensor I55 must sense at the same time, and the metal probe can be electrified.
Misoperation protection measures are as follows: because the metal probe is pressed on the PLC, if the metal probe is not withdrawn, the transposition air cylinder 29 is moved by misoperation, the metal probe is long, narrow and thin in size and easy to damage, and the PLC is damaged by 220V electricity of the metal probe belt.
