The controller 430 controls the lifting of the second elevator 460 so as to be positioned so as to generate a transfer signal when the slot 210 corresponding to the selected job is positioned horizontally with the top surface of the substrate stage 410. And, when receiving the transfer signal from the controller 430 is composed of a transfer unit 440 to take out the substrate mounting module 300 corresponding to the selected job from the loading unit 200 and to transfer to the upper surface of the stage 410. .

In addition, the stage 410 is provided with a detection sensor 450 to determine whether the substrate mounting module 300 for the operator is raised, the detection sensor 450 is connected to the controller 430.

The controller 430 controls the second elevator 460 when receiving the detection signal of the detection sensor 450, so that the slot 210 layer of the loading part 200 in which the substrate mounting module 300 is stored is stored. The loading unit 200 is raised and lowered so as to be elevated to a position parallel to the upper surface of the stage 410, and a transfer signal is generated in the transfer unit.

Subsequently, the transfer unit 440 receives the transfer signal from the controller 430 and pushes the substrate mounting module 300 used for the driver into the slot 210 that was stored in the loading unit 200.

In addition, when the substrate mounting module 300 for the technician is not detected by the sensor 450 of the stage 410, the controller 430 controls the lifting of the second elevator 460 to allow the loading unit ( The 200 is lifted and positioned so that the slot 210 layer containing the substrate seating module 300 corresponding to the selected job is flush with the top surface of the substrate stage 410. Then, the transfer unit 440 pulls out the substrate seating module 300 corresponding to the selected job from the loading unit 200 and transfers it to the upper surface of the stage 410.

Here, the transfer unit 440 may be made of the same configuration as the embodiment.

As described above, the present invention does not open the cover of the screen printer when changing the production model of the substrate, and automatically replaces it with a substrate seating module corresponding to the size of the substrate, thereby eliminating the trouble of replacement work and shortening the working time. It improves the efficiency of the work, and has the effect of improving the quality and productivity of the substrate by keeping the internal temperature of the screen printer constant.
