The lifting frame 5 then drives the vacuum suction cup 6 to move down until the vacuum suction cup 6 contacts the workpiece. Subsequently, the vacuuming mechanism extracts the air from the vacuum suction cup 6, creating a negative pressure inside to firmly adsorb the workpiece. Then, hydraulic cylinder 4 drives the workpiece to move up, exposing the contact area with the transport component 2. Reference Figure 1 , Figure 3 and Figure 5 In a preferred embodiment, a vacuuming mechanism is mounted on the fixed frame 3 and is used to extract air from the vacuum suction cup 6 to create a negative pressure state; the vacuuming mechanism includes: Vacuum pump 8 is fixedly mounted on mounting bracket 3; A suction hose 9 is installed on the vacuum pump 8, and one end of the suction hose 9 is fixedly connected to the vacuum pump 8.

One end is fixedly connected to the sealing hollow plate 10, and the other end is fixedly connected to the vacuum suction cup 6.

[0027] During operation, the vacuum pump 8 is started. The vacuum pump 8 draws air from the sealed hollow plate 10 through the extraction hose, creating a negative pressure inside. The sealed hollow plate 10 draws air from the vacuum suction cup 6 through the connecting pipe 11, creating a negative pressure, which enables the vacuum suction cup 6 to stably adsorb the workpiece. Support plate 7 is fixedly mounted on support frame 1; used to support sealing box 12; Reference Figure 2 and Figure 4 In a preferred embodiment, a blower mechanism is disposed on the support plate 7 and is used to blow hot air onto the workpiece to be dried; the blower mechanism includes: The sealed box 12 is fixedly mounted on the support plate 7; A heating component 16 is fixedly installed inside the sealed box 12 for heating the air inside the sealed box 12.

[0028] A temperature sensor 17 is installed inside the sealed box 12. The temperature sensor 17 is fixedly connected to the sealed box 12 and is used to detect the temperature inside the sealed box 12 in real time.

[0029] A perforated flow equalization plate 13 is mounted on a fixed frame 3 and is fixedly connected to the fixed frame 3; The blower duct 14 is mounted on the sealed box 12, with one end fixedly connected to the sealed box 12 and the other end fixedly connected to the perforated flow equalization plate 13. An electric blower 15 is fixedly mounted on the sealed box 12.

[0030] During operation, the heating component 16 is activated via the monitoring panel 22 to heat the air inside the sealed box 12. During this process, the temperature sensor 17 detects temperature changes in real time and feeds them back to the monitoring panel 22. The electric blower 15 is activated, and the electric blower 15 blows hot air into the porous flow equalization plate 13 through the blower pipe 14. The porous flow equalization plate 13 blows the hot air toward the workpiece, which dries the workpiece. Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a hot air recovery mechanism is mounted on the fixed frame 3 and is used to recover the processed hot air. The hot air recovery mechanism includes: The gas collection hood 18 is fixedly mounted on the mounting bracket 3; Drying chamber 19 is mounted on support frame 1 and fixedly connected to support frame 1. Drying chamber 19 contains desiccant for absorbing water vapor in hot air.

The second recovery pipe 21 is installed on the drying box 19. One end of the second recovery pipe 21 is fixedly connected to the drying box 19, and the other end is fixedly connected to the sealing box 12.

[0032] Working principle: The workpiece to be dried is transported to the fixed frame 3 via the transport component 2. The heating component 16 is activated via the monitoring panel 22 to heat the air inside the sealed box 12.

The electric blower 15 is then activated, blowing hot air through the blower pipe 14 into the porous flow equalization plate 13. The porous flow equalization plate 13 blows the hot air onto the workpiece, drying the unshielded areas of the workpiece. The hot air passes through the workpiece and is blown into the air collection hood 18, and then through the first recovery pipe 20 into the drying chamber 19. The desiccant in the drying chamber 19 dries the air in the recovered air. The water vapor is absorbed and finally returned to the sealed box 12 through the second recovery pipe 21. After the unshielded area is dried, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the lifting frame 5 to move down, and the lifting frame 5 drives the vacuum suction cup 6 to move down until the vacuum suction cup 6 contacts the workpiece. The vacuum pump 8 is activated. The vacuum pump 8 draws air from the sealed hollow plate 10 through the extraction hose, creating a negative pressure inside. The sealed hollow plate 10 draws air from the vacuum suction cup 6 through the connecting pipe 11, creating a negative pressure, so that the vacuum suction cup 6 can stably adsorb the workpiece. Finally, the hydraulic cylinder 4 drives the workpiece to move up, exposing the contact area with the transport component 2, and then dries it.
