The turntable 10 is located in the circular groove 101 and is slidably connected to the inner wall thereof. A plurality of perforated plates 11 are arranged on the turntable 10 in a circular array around its axis, so as to sequentially form a processing station, a material unloading station, a material loading station and an alternative station on the operating table 1 along the rotation direction of the turntable 10, wherein the processing station is located directly below the screen printing plate 4. The rotary drive member comprises a motor 12, which is arranged on the operating table 1, and the output end of the motor 12 is connected to a rotating shaft 104, which is connected to the turntable 10 and is rotatably connected to the operating table 1, so as to drive the turntable 10 to rotate through the motor 12, so as to rotate the carrier on the alternative station to the processing station, and rotate the carrier on the processing station to the material unloading station, and at the same time rotate the carrier on the processing station to the alternative station. The adsorption mechanism includes an exhaust pipe 16 and a fan 17. The air inlet of the exhaust pipe 16 is connected to the pores of each porous plate 11, and the air outlet of the exhaust pipe 16 is connected to the outside. The fan 17 is located at one end of the exhaust pipe 16 near the air outlet, so that the carrier is fixed on the porous plate 11 by the fan exhaust to prevent it from shifting during the rotation and switching of the workstation. The operating table 1 is sequentially provided with a circular groove 101, a short groove 102 and a through hole A103 from top to bottom, and the three are connected to each other, and the through hole A103 is connected to the outside. The turntable 10 is located in the circular groove 101 and is slidably connected to its inner wall. The exhaust pipe 16 is covered on the outside of the through hole A103.

[0029] Embodiment 2

[0030] like Figure 2 As shown, the utility model proposes a fixed working platform for a vertical screen printer. Compared with the first embodiment, a plurality of through holes B1001 are arranged on the turntable 10, and each through hole B1001 is respectively connected with the fine holes of the corresponding side porous plate 11 and the short groove 102. A sealing plate A13 is arranged in the short groove 102, and the sealing plate A13 is located below the porous plate 11 corresponding to the unloading station, and the sealing plate A13 is attached to and slidably connected with the turntable 10 to seal the through hole B1001 in the unloading station.

[0031] In this embodiment, after the printing of the carrier at the processing station on the turntable 10 is completed, the motor 12 drives the turntable 10 to rotate and transfers the processed carrier to the unloading station. At this time, the through hole B1001 corresponding to the unloading station is closed by the sealing plate A13, and the pores of the porous plate 11 on the unloading station are closed. The carrier on the porous plate 11 is no longer adsorbed on the porous plate 11 by the airflow, which is convenient for the staff to remove it. When loading at the loading station, it is inevitable that the carrier is not placed correctly. At this time, the hydraulic cylinder B15 is started, and the hydraulic cylinder B15 drives the sealing plate B14 to slide and close the through hole B1001 corresponding to the loading station to offset the adsorption effect of the gas on the carrier at this station, so as to facilitate the adjustment of the position of the carrier.
