Furthermore, in this embodiment, the testing area T of the platform 1 can provide multiple (for example: two) carriers 222 of the conveying element 22 located therein at the same time, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the testing area T may also only provide a carrier 222 of the conveying element 22 therein.

The movable isolation cover 3 is a metal cover in this embodiment and is set corresponding to the testing area T of the platform 1 . Moreover, the movable isolation cover 3 is illustrated as being disposed directly above the platform 1 (or the testing area T) in FIGS. 1 and 2 , but the present invention is not limited thereto.

In more detail, the movable isolation cover 3 can move toward the platform 1 to close the test area T, so as to cover at least one test object 200 located in the test area T. As shown in FIG. Accordingly, in this embodiment, the test system 100 uses the structure of the platform 1 and the transmission mechanism 2 to enable the test system 100 to ensure that the test object 200 has a standard isolation during the test process, and can also effectively It can greatly improve the degree of overall automation operation, thereby achieving the effect of saving manpower and reducing the test schedule.

As shown in Figures 1 and 2, when the movable isolation cover 3 is in the open position, the movable isolation cover 3 is spaced apart from the platform 1, so that a plurality of conveying parts 22 can move through the platform 1 (or test area T) . Furthermore, as shown in FIG. 3 , when the movable isolation cover 3 is in the closed position, the mobile isolation cover 3 abuts against the platform 1 to form at least one enclosed space E together to surround it, and then accommodate it in the test area T At least one test object 200 of. In this embodiment, the movable isolation cover 3 is formed by abutting against the platform 1 and the metal bracket 221 of each conveying element 22 inside the platform 1, thereby enclosing and forming two closed spaces E, and then respectively accommodating two 200 test items.

Further, as shown in FIG. 3 , when the movable isolation cover 3 closes the test area T and covers at least one test object 200 therein (such as: the movable isolation cover 3 is in the closed position), the two conductive elastic bodies 13 The inner edges of the inner edges are elastically pressed against the metal brackets 221 of the two transmission parts 22, so that the inlet 11 and the outlet 12 are respectively closed by the metal brackets 221 of the two transmission parts 22, and pressed against by the two conductive elastic bodies 13. One of the two conveyors 22 (such as: the conveyor 22 at the entrance 11 in FIGS. 3 and 4 ), the test object 200 on it is located in the test area T, so as to effectively lift the test object 200 The degree of isolation during the test, but the invention is not limited thereto.

For example, in other embodiments not shown in the present invention, the platform 1 may not be provided with any conductive elastic body 13 at the inlet 11 and the outlet 12, and each transmission member 22 is additionally provided with a conductive elastic body, which covers The shape of the metal bracket 221 corresponds to the inlet 11 (or the outlet 12); or, the way the inlet 11 or the outlet 12 is closed by the metal bracket 221 can also be adjusted and changed according to the design requirements, and is not limited to the combination of the conductive elastomer 13 Metal bracket 221.

In addition, as shown in FIG. 3, when the movable isolation cover 3 closes the test area T and covers at least one test object 200 therein (such as: the movable isolation cover 3 is in the closed position), the test member 4 is used to test at least one test object 200. The test object 200 is tested and generates a test result signal, and the signal processing device 5 can be used to receive the test result signal. It should be noted that, if the number of test objects 200 is multiple, the number of closed spaces E is also multiple, for accommodating multiple test objects 200 respectively, and the test member 4 can have The multiple detection parts 41 are used to test multiple test objects 200 synchronously.

Furthermore, a plurality of scanners 6 include an entrance scanner 61 and an exit scanner 62 installed outside the movable isolation enclosure 3 (or the closed space E), and the entrance scanner 61 and the exit scanner 62 In this embodiment, they are respectively installed at opposite ends of the movable isolation cover 3, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the entrance scanner 61 and the exit scanner 62 may not be in contact with the movable isolation enclosure 3 .

Further, the position of the entrance scanner 61 corresponds to the entrance 11 for scanning the test object 200 on the transport member 22 adjacent to the entrance 11, so that the signal processing device 5 can record the test items scanned by the entrance scanner 61. The testing process of the object 200.

Furthermore, the position of the exit scanner 62 corresponds to the exit 12, and is used for scanning the test object 200 on the conveyer 22 adjacent to the exit 12, so that the signal processing device 5 can perform a preset mode (such as: display on the screen, alarm sound, or transmit a signal to the hand-held device) to inform the operator about the test result (eg, pass or fail) of the test object 200 scanned by the entrance scanner 61 .
