Of course, a horizontal position detecting unit is further included to detect whether the horizontal movement of the transfer unit 22 reaches the transfer position and the material conveying position, which may be position sensors respectively provided corresponding to the transfer position and the material conveying position.

The utility model discloses a test system's working process includes:

(1) the feeding process comprises the following steps:

when the material detection unit detects that a predetermined amount of PCB is input on the transfer unit 22 located at the material conveying position 31, the control mechanism triggers the moving motor to start, the transfer unit 22 is driven to move towards the transfer position 32, and at the moment, the fork rod 41 on the feeding device 1 is located at an initial position which is not lifted, namely, when the transfer unit 22 moves to the transfer position 32, the fork rod 41 just enters the transfer groove 223 and is inserted below the PCB, and the moving motor stops moving after the transfer unit 22 moves to the transfer position 32;

then the control mechanism controls the lifting motor to start, the lifting motor drives the fork rod 41 to ascend, the PCB at the top of the fork rod reaches the material taking position 33, and after the PCB on the upper surface of the fork rod 41 triggers the upper limiting sensor at the material taking position, the control mechanism controls the lifting motor to stop moving; and then the control mechanism controls the automatic aligning device to perform deviation rectifying operation, and after the deviation rectifying operation is completed, the control mechanism controls the sucker component to perform material grabbing operation to grab the material onto a test platform of the test equipment 6.

Meanwhile, after the transfer unit 22 transfers the materials to the fork rod 41, the transfer unit is driven by the moving motor to return to the material conveying position 31 and perform the feeding operation of the next batch of materials; when the material detection unit on the fork rod 41 detects that no material exists on the fork rod, the control mechanism controls the fork rod 41 to descend to the initial position; when the reset sensor detects that the fork rod 41 returns to the initial position, the control mechanism controls the fork rod to stop moving, and simultaneously the control mechanism controls the transfer unit 22 to move to the transfer position 32, so that the loading operation of the next round is performed.

(2) The testing process comprises the following steps:

the test equipment 6 tests the open circuit of the PCB and outputs the test result to the control mechanism, and the control mechanism outputs corresponding motion instructions to the material taking mechanism of the discharging equipment 5 according to the test result, namely, the PCB which is qualified in test, bad in short circuit and bad in open circuit is respectively output to the corresponding material receiving device.

(3) And (3) discharging:

the sucker component grabs and places the PCB qualified in the test platform on the fork rod 41, when the PCB accumulated on the fork rod 41 reaches a preset amount, the material detection unit on the fork rod 41 is triggered, the control mechanism controls the lifting motor to start, the lifting motor drives the fork rod 41 to descend, when the fork rod 41 descends to a preset position, the lower limit sensor is triggered, at the moment, the fork rod 41 is just in the transfer groove 223 of the transfer unit 22, and the control mechanism controls the lifting motor to stop descending;

meanwhile, the PCB is delivered to the transfer unit 22 through the descending of the fork rod 41, when the material detection unit on the transfer unit 22 detects that a preset amount of PCB is input, the control mechanism triggers the motor of the driving unit 23 to start, the driving unit 23 drives the transfer unit 22 to move towards the direction far away from the discharging device 5 until the PCB stops after moving to the material conveying position 31, and at the moment, the PCB can be taken away through an external mechanism.

Meanwhile, after the fork rod 41 delivers the materials to the transfer unit 22 and the transfer unit 22 leaves the transfer position 32, the fork rod 41 is controlled to return to the material taking position 33 for the output operation of the next batch of materials.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
