S104 supplies power to the test cassette 10 located at the test station for a preset time period to operate at least one workpiece 01.

S105, if the test cassette 10 fails to report an error during the power supply, determines the workpiece 01 located on the workpiece test site 12 corresponding to the error report information as a test-failed workpiece.

In step S105, the electronic device 50 will continuously receive a signal fed back from the test station during the power supply process, which specifically includes the operation information of each workpiece 01. When the electronic device 50 receives the error information, the error information is analyzed, and the workpiece 01 located on the workpiece test site 12 of the test box 10 corresponding to the error information is determined as a test-failed workpiece. Optionally, the electronic device 50 may also issue an error warning to remind the processing of the failed test workpiece. And if the power supply process is finished and error information is not generated, determining that the corresponding workpiece 01 is a workpiece which is successfully tested and can be put into the market for use.

In order to improve the testing efficiency, the embodiment provides a method for processing the test cartridge 10 and the workpiece 01 after the test, that is, after the power supply is finished, the conveying mechanism 46 is started to move the test cartridge 10 from the test station 441 to the discharge port 47 of the test room 40, and then the second feeding mechanism 70 is adopted to convey the test cartridge 10 from the discharge port 47 of the test room 40 to the second support 22 of the second loading platform 60; after the test cartridge 10 is stably loaded on the second rack 22, all the workpieces 01 on the test cartridge 10 are disassembled using the robot arm.

In one embodiment, after the step (3) of detaching the at least one workpiece 01 from the workpiece testing position 12 of the testing box 10, the method further includes:

at least one workpiece 01 is determined to be a workpiece 01 which is successfully tested, and at least one workpiece 01 is placed on the second functional testing mechanism 90 for functional testing.

Specifically, in order to improve the yield of the workpieces 01 put on the market, the workpieces 01 subjected to the test in the test room 40 are transferred to the second performance testing mechanism 90 to be subjected to the performance test. Alternatively, the function testing functions performed by the first function testing means 80 and the second function testing means 90 may be the same, and the function testing performed by the first function testing means 80 may be interpreted as an initial test (simply testing whether or not to conduct electricity, etc.), and the function testing performed by the second function testing means 90 may be interpreted as a retest (further testing the properties of the workpiece 01). Specifically, when the test cassette 10 is stably transferred to the second rack 22 of the second loading platform 60, the robot arm is used to transfer the workpiece 01, which has been tested successfully in the test room 40, on the test cassette 10 to the second functional testing mechanism 90; other test failed workpieces 01 will be transferred to the failed workpiece handling area using the robotic arm.

In one embodiment, after the step (3) of detaching the at least one workpiece 01 from the workpiece testing position 12 of the testing box 10, the method further includes:

the test box 10 is transferred from the second loading platform 60 to the first loading platform 20, and whether the test box 10 and each workpiece testing position 12 on the test box 10 are operating normally is detected by the detection mechanism.

If any one of the workpiece test sites 12 is abnormal in detection result, the workpiece test site 12 is identified and the workpiece test site 12 is positioned when the next round loads the workpiece 01 on the cassette 10.

Specifically, in consideration of the problem that the test box 10 may be damaged after being used for multiple times, in order to improve the accuracy of the test, after the workpiece 01 on the test box 10 is removed through the step (3), the test box 10 is tested before being put into the next round of use, and then the test box 10 and each workpiece test site 12 on the test box 10 are tested. Specifically, the empty test box 10 is transferred from the second rack 22 of the second loading platform 60 to the second rack 22 of the first loading platform 20 by the transfer mechanism 100, and when the test box 10 is stably loaded on the second rack 22 of the first loading platform 20, the test contact 11 of the test box 10 is electrically connected to the third thimble 111 of the detection mechanism 110, and then the detection mechanism 110 is started to detect each workpiece test site 12 on the test box 10 and the test box 10, where the detection may include whether the electrical connection is stable, whether the signal transmission is normal, and the like. Removing the test cartridge 10 from the test equipment if the overall test of the test cartridge 10 is abnormal; if only one of the workpiece test sites 12 on the cassette 10 is detected as abnormal, the workpiece test site 12 is identified and the workpiece test site 12 is positioned when the next round of loading the workpiece 01 on the cassette 10. When the number of the abnormal workpiece testing sites 12 on the testing box 10 exceeds a predetermined threshold (or may be a percentage, for example, 50% of the total number of the abnormal workpiece testing sites 12), the testing box 10 is removed.

The foregoing is only a partial embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations should also be regarded as the protection scope of the present application.
