Meanwhile, the specifications of the module 20 to be picked up may be different, and the pick-up tool 648 is shown in FIGS. 9A and 9B so that the module handler according to the present invention can handle two or more types of modules 20. As described above, the distance between the pair of grippers 641 may be adjusted.

In addition, the pair of grippers 641 may be provided with buffer members made of a material such as a flexible synthetic resin so that both ends of the module 20 can be smoothly gripped.

Meanwhile, when the module 20 is separated from the test socket 210, the pair of grippers 541 descend and press the hooking part 219 to hold the module 20 as shown in FIG. 9B. The coupled state of the test socket 210 may be released.

Here, when the hooking part 219 is pressed, the module 20 may protrude upward. In order to prevent this, the pressing part 649 descends to prevent the module 20 from excessively protruding upward. there is.

When the module 20 is uncoupled from the test socket 210, the pick-up tool 648 picks up the module 20 from the test socket 210 through the process shown in FIGS. 9C and 9D. can do.

Meanwhile, the pick-up tool 648 can seat the module 20 in the test socket 210, that is, mount it through the process shown in FIGS. 10A to 10C.

At this time, when the module 20 is seated on the test socket 210, the pick-up tool 648 moves the module 20 up and down so that the module 20 can be stably mounted on the test socket 210. A pressurization unit 649 for pressurizing the test socket 210 may be included.

When the module 20 is seated on the test socket 210, the pressing unit 649 tests the module 20 by moving the module 20 up and down so that the module 20 can be stably mounted on the test socket 210. As a configuration for pressing the socket 210, various configurations are possible.

The shuttle unit 310 is installed to be movable by sequentially circulating a loading position, a test, and an unloading position set on the movement path (L), and the plurality of modules 20 from the first buffer unit 330 ) as a configuration for receiving and passing them to the test unit 200, various configurations are possible.

Here, the loading position is set to a position where the shuttle unit 310 is located to receive the module 20 from the first buffer unit 330 described above, and the unloading position is the second buffer unit 340 described later. ) is set to a position where the shuttle unit 310 is located to deliver the module 20.

The test unit is a module tool 640 that picks up the module 20 from the test socket 210 as a position where the test unit 200 delivers the module 20 to be tested and receives the module 20 that has been inspected. ) is set to a position where the module 20 can be delivered from the pick-up tool 648.

Meanwhile, the shuttle unit 310 may be configured similarly to the first buffer unit 330 described above.

For example, as shown in FIGS. 6 and 7 , the shuttle unit 310 may be composed of a shuttle plate 311 provided with a plurality of pockets 312 and 313 in which the module 20 is seated. .

The shuttle plate 311 has a plurality of pockets 312 and 313 in which the module 20 is seated, and various configurations are possible depending on the arrangement structure of the plurality of pockets 312 and 313.
