The first double-head material moving unit 3 is arranged to be a double-head material taking and placing structure, a first material to be tested can be taken out of the material tray through the double-head material taking and placing structure, before the first material is placed into the rotary correcting unit 4, a second material which is already present in the rotary correcting unit 4 and is tested is taken out through the double-head material taking and placing structure, and then the first material is placed into the rotary correcting unit 4. The first material in each embodiment of the utility model refers to the untested material to be tested; the second material refers to a tested material after the test is finished or refers to a material which is tested and has a test result of qualified test, and the first material is converted into the second material after the test is finished.

The test unit 8 is used for testing the material, such as testing the responsiveness parameter of the material.

In the test process, after the first material is moved out of the material tray, the first material passes through the rotary correction unit 4 and the rotary material changing unit 6 in sequence and is finally transferred into the test unit 8 for testing; after the second material which is tested in the test unit 8 is moved out of the test unit 8, the second material passes through the rotary material changing unit 6 and the rotary correction unit 4 in sequence, and finally returns to the material tray.

The first material and the second material are in the same transfer path, and the situation that the first material and the second material need to occupy the same material receiving position of the same structural unit exists. For example, in the process that the first double-headed material moving unit 3 transfers the first material in the material tray to the rotation correcting unit 4, if the rotation correcting unit 4 is occupied by the second material transferred from the rotation material changing unit 6, the first double-headed material moving unit 3 first takes out the second material (at this time, the first double-headed material moving unit 3 simultaneously takes out one first material and one second material), the rotation correcting unit 4 is in an idle state, then the currently taken first material is put into the rotation correcting unit 4, and the first double-headed material moving unit 3 puts the second material taken out from the rotation correcting unit 4 back into the material tray when taking out the next first material from the material tray.

In the process that the second dual-head material moving unit 5 transfers the material in the rotary correcting unit 4 to the rotary material changing unit 6, if one end of the rotary material changing unit 6 located in the second material taking range is occupied by the second material transferred from the testing unit 8, the second dual-head material moving unit 5 first takes out the second material (at this time, the second dual-head material moving unit 5 simultaneously takes in one first material and one second material), one end of the rotary material changing unit 6 located in the second material taking range is in an idle state, then the second dual-head material moving unit 5 puts the currently taken first material into one end of the second material taking range, and after taking out the next first material from the rotary correcting unit 4, the second material taken from the rotary material changing unit 6 is put into the rotary correcting unit 4. In this process, the third double-headed material transfer unit 7 takes out the first material located in one end of the rotary material change unit 6 of the third material taking-out range and puts in the second material taken out of the test unit 8.

In an embodiment, the testing apparatus may further include a waste recycling unit 100, the waste recycling unit 100 is connected to the fixing plate 12, and the waste recycling unit 100 is disposed between the rotary material changing unit 6 and the testing unit 8. For materials with a test result that is not qualified, the materials can be transferred to the waste recovery unit 100; for materials that have a test result that is acceptable, it may be returned to the tray. Of course, the testing device may not be provided with the waste recovery unit 100, and whether the test result is qualified or not, the test result is returned to the material tray, and the qualified and unqualified materials in one material tray are distinguished by constructing the association table of the material identifier and the test result.

Through the structure, the rotary correction unit 4 can correct the position state of the material, so that the position state of the material meets the test requirement, and the accuracy of the test result is improved.
