[0037] The belt is locked by the cooperation of the tensioning screw 27 and the belt tensioning idler pulley 28 to ensure that the belt will not fall off during the transmission of the test plate.

[0038] The auxiliary conveyor line A is equipped with an auxiliary conveyor line lifting device A6 and a lifting device positioning photoelectric sensor D11. The lifting device positioning photoelectric sensor D11 is located at the end of the auxiliary conveyor line A away from the main conveyor line.

[0039] The auxiliary production line B is equipped with an auxiliary production line lifting device B7 and a lifting device positioning photoelectric sensor E12. The auxiliary production line lifting device B7 is located at the end of the auxiliary production line B away from the main production line. The lifting device positioning photoelectric sensor E12 is located on the side of the auxiliary production line lifting device B7 away from the auxiliary production line lifting device A6. The auxiliary production line lifting device B7 and the auxiliary production line B are connected in a liftable manner. The auxiliary production line lifting device B7 and the lifting device positioning photoelectric sensor E12 are electrically connected to the PLC controller.

[0040] The test board 1 moves along the auxiliary production line A to the auxiliary production line lifting device A6, and touches the lifting device positioning photoelectric sensor D11, which sends a signal to the PLC controller. The PLC controller uses a cylinder to control the auxiliary production line lifting devices A6 and B7 to rise. The motor of the auxiliary production line lifting device A6 controls the belt to transport the test board 1 onto the auxiliary production line lifting device B7. The motor of the auxiliary production line lifting device B7 controls the belt to transport the test board 1 into position, and touches the lifting device positioning photoelectric sensor E12, which sends a signal to the PLC controller. The auxiliary production line lifting devices A6 and B7 reset, and the test board 1 moves along the auxiliary production line B.

[0041] The auxiliary flow line B is equipped with an auxiliary flow line blocker 19 and a buffer zone outlet plate position photoelectric sensor 14 at one end near the main flow line. The buffer zone outlet plate position photoelectric sensor 14 is located at the rear end of the auxiliary flow line blocker 19 along the conveying direction of the auxiliary flow line B. The buffer zone outlet plate position photoelectric sensor 14 and the auxiliary flow line blocker 19 are electrically connected to the PLC controller.

[0042] The test board 1 moves along the auxiliary flow line B and touches the photoelectric sensor 14 of the buffer area. The sensor sends a signal to the PLC controller. The PLC controller uses a cylinder to control the auxiliary flow line stopper 19 to descend and the main flow line lifting device B4 to rise. At this time, the auxiliary flow line, together with the motor and belt of the main flow line lifting device B4, sends the test board from the buffer area 24 to the main flow line lifting device B4.

[0043] Both ends of the auxiliary assembly line lifting device A6 and the auxiliary assembly line lifting device B7 are equipped with belt conveyor lines.

[0044] Working principle of the invention:

[0045] There are a total of six motion states for the board under test to enter and exit the test station. The control logic for the six motion states is as follows:

[0046] The control logic for Mode1 is as follows:

[0047] The test station is boardless, and the board under test in the waiting area does not need to enter the buffer area;

[0048] Specifically, the board under test 1 moves on the main water line 21, enters the waiting area 23, touches the lifting device positioning photoelectric sensor A8, which sends a signal to the PLC controller. At this time, the PLC controller only receives the signal from the lifting device positioning photoelectric sensor A8, and the board under test directly enters the test area.

[0049] Specifically, the PLC controller uses a cylinder to control the main water line blocker A16 and the main water line blocker B17 to descend. At this time, the board under test flows through the main water line lifting device A3 and the main water line lifting device B4. Subsequently, the main water line blocker A16 and the main water line blocker B17 are reset.

[0050] The test board 1 continues to move along the main water line 21. When it reaches the main water line lifting device C5 and touches the lifting device positioning photoelectric sensor C10, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the main water line lifting device C5 to rise. Its motor controls the belt to transport the test board 1 onto the test station. At this time, the test board 1 enters the test area 25. The test station motor controls the belt to transport the test board 1 into position and touches the test station positioning photoelectric sensor 13. At this time, the test indicator light 26 lights up, indicating that the test board 1 has moved into position.

[0051] The employee begins the test. After the test is completed, the employee presses the eject button 20, which sends a signal to the PLC controller. The PLC controller controls the test bench motor to send the test board 1 onto the main water line lifting device C5 with the belt (the test indicator light 26 dims). The motor of the main water line lifting device C5 controls the belt to transport the test board 1 into place. When it touches the lifting device's positioning photoelectric sensor C10, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the main water line lifting device C5 to descend. Then, the main water line stopper C18 descends, and the test board 1 flows into the next process.

[0052] The Mode2 control logic is as follows:

[0053] The test bench has boards, and the boards under test enter the buffer area in the waiting area.

[0054] Specifically, when the board under test 1 is being tested on the test station, the photoelectric sensor 13 of the test station in position receives a signal, and the indicator light 26 under test lights up.

[0055] When a new test board 1 moves along the main water line 21 and touches the lifting device positioning photoelectric sensor A8, it sends a signal to the PLC controller. At this time, the PLC controller simultaneously receives signals from the lifting device positioning photoelectric sensor A8 and the test station positioning photoelectric sensor 13. Then the test board first enters the buffer area 24 and then enters the test area 25.

[0056] Specifically, the board under test is raised by the main flow line lifting device A3 controlled by a cylinder. The motor of the main flow line lifting device A3 controls the belt to transport the board under test 1 onto the buffer area 24. The board under test 1 moves along the auxiliary flow line 22 to the auxiliary flow line lifting device A6. When it touches the lifting device positioning photoelectric sensor D11, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the auxiliary flow line lifting devices A6 and B7 to rise. The motor of the auxiliary flow line lifting device A6 controls the belt to transport the board under test 1 onto the auxiliary flow line lifting device B7. The motor of the auxiliary flow line lifting device B7 controls the belt to transport the board under test 1 into position. When it touches the lifting device positioning photoelectric sensor E12, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the auxiliary flow line lifting devices A6 and B7 to reset.

[0057] The test board 1 moves along the auxiliary flow line 22 and touches the photoelectric sensor 14 of the buffer area. The sensor sends a signal to the PLC controller. The PLC controller uses a cylinder to control the auxiliary flow line stopper 19 to descend and the main flow line lifting device B4 to rise. At this time, the auxiliary flow line, together with the motor and belt of the main flow line lifting device B4, sends the test board from the buffer area 24 to the main flow line lifting device B4.

[0058] After the test board 1 moves into position, it touches the lifting device positioning photoelectric sensor B9, which sends a signal to the PLC controller. The PLC controller uses a cylinder to control the main water line lifting device B4 to descend, and then the main water line stopper B17 descends. The test board 1 is then conveyed along the main water line 21 to the main water line lifting device C5. After touching the lifting device positioning photoelectric sensor C10, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the main water line lifting device C5 to rise, and its motor controls the belt to convey the test board onto the test station. At this time, the test board enters the test area 25, and the test station motor controls the belt to convey the test board 1 into position, touching the test station positioning photoelectric sensor 13. At this time, the test indicator light 26 lights up, indicating that the test board 1 has moved into position.

[0059] The employee begins the test. After the test is completed, the employee presses the eject button 20, which sends a signal to the PLC controller. The PLC controller controls the test bench motor to send the test board 1 onto the main water line lifting device C5 with the belt (the indicator light for the test board dims). The motor of the main water line lifting device C5 controls the belt to transport the test board 1 into place. When it touches the lifting device's positioning photoelectric sensor C10, it sends a signal to the PLC controller. The PLC controller uses a cylinder to control the main water line lifting device C5 to descend. Then, the main water line stopper C18 descends, and the test board 1 flows into the next process.

[0060] The Mode3 control logic is as follows:

[0061] Both the waiting area 23 and the test area 25 have boards under test 1. The buffer area 24 has boards under test, but they are moving on the auxiliary pipeline 22 and have not yet touched the buffer area's board exit photoelectric sensor 14. At this time, after the test board in the waiting area 25 has completed its test, the test board 1 in the waiting area 23 goes first into the test area 25. After the test is completed, the test board in the buffer area 24 then enters the test area for testing.

[0062] The Mode4 control logic is as follows:

[0063] There is a board under test in waiting area 23, no board under test in test area 25, and a board under test in buffer area 24, but it is moving on auxiliary pipeline 22 and has not yet touched the board exit photoelectric sensor 14 in buffer area. At this time, the board under test in waiting area goes first and enters test area. After the test is completed, the board under test in buffer area enters test area for testing.

[0064] The Mode5 control logic is as follows:

[0065] Both the waiting area 23 and the test area 25 have boards under test (SUTs), and the buffer area 24 has an SUT that has touched the buffer area ejection photoelectric sensor 14. At this time, after the SUT in the test area 25 has completed its test, the SUT in the buffer area 24 goes first into the test area. After the test is completed, the SUT in the waiting area then enters the test area for testing.

[0066] The Mode6 control logic is as follows:

[0067] Waiting area 23 has a board under test (DUT), testing area 25 has no DUT, and buffer area 24 has a DUT that has touched the buffer area ejection photoelectric sensor. At this time, the DUT in the buffer area goes first into the testing area, and after the test is completed, the DUT in the waiting area goes into the testing area for testing.

[0068] Among them, Mode1 and Mode2 are the basic motion states, and Mode3, Mode4, Mode5, and Mode6 are the topological structures of Mode1 and Mode2.
