[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a substrate is placed inside a placement table, at which time the top surface of the substrate protrudes from the placement table and the substrate cannot move horizontally. Then, the conveyor belt is started and the substrate is transported to the bottom of the first cleaning mechanism. Then, the first electric push rod is started to drive the cleaning sponge to move downward until the bottom surface of the cleaning sponge is slightly lower than the top surface of the substrate, thereby preventing the cleaning liquid from splashing onto the horizontal push rod. At the same time, the drainage pump is started to transport the cleaning liquid inside the liquid storage tank to the nozzle, and the nozzle is sprinkled on the surface of the substrate.

Then, the horizontal push rod is started to drive the placement table and the substrate to make reciprocating linear motion, thereby comprehensively cleaning the upper surface of the substrate to avoid stains interfering with substrate detection.

[0017] 2. In the present invention, the substrate is transported to the bottom of the first drying mechanism by a conveyor belt, and then the second electric push rod is started to drive the drying box to move downward until the drying box is sleeved on the outer surface of the placement table. At this time, the openings at both ends of the U-shaped tube are inserted into the gap formed by the substrate and the placement table, and then the water pump is started to transport the cleaning liquid accumulated in the gap to the temporary storage box. At the same time, the first drying lamp is in working condition to dry the substrate. When the accumulated cleaning liquid is extracted, the water pump is still in working condition, so that the water vapor generated by drying is also transported to the temporary storage box, thereby improving the drying rate.

[0018] 3. In the present invention, the conveyor belt is started and the substrate is transported to the bottom of the first visual detector, so that the upper surface of the substrate is inspected. After the inspection is completed, if the substrate is unqualified, it is removed; if the substrate is qualified, it is transported to the bottom of the adsorption mechanism, and then the third electric push rod is started to drive the limit frame to move downward until the limit frame is sleeved on the outer surface of the substrate. At this time, the suction cup will be against the upper surface of the substrate, and then the electric control valve will be briefly opened. At this time, the liquid inside the temporary storage box will be transported to the inside of the suction cup, thereby improving the sealing of the suction cup.

[0019] 4. In the present invention, the servo motor is started to drive the carrier plate to rotate until the cleaning box is moved to the bottom of the substrate, and then the substrate is driven to move downward by the third electric push rod, and the lower surface of the substrate is made to fit with the cleaning roller. Then the drive motor is started to drive the cleaning roller to rotate. Since the cleaning roller is bubbled in the cleaning liquid, the lower surface of the substrate can be cleaned. When the cleaning is completed, the carrier plate is continued to be driven to rotate, so as to move the drying chamber to the bottom of the substrate. Then the substrate is dried by the second drying lamp, and finally the carrier plate is driven to rotate so that the second visual detector detects the lower surface of the substrate.
