[0023] like Figure 1 and2 As shown, a drying device for workpieces after electrophoretic coating includes a hanging rail 1 and a drying chamber 2 with open ends. A lifting device is installed on the hanging rail 1 for transporting workpieces 3 to the drying chamber 2. The lifting device is used to hang the electrophoretic workpieces 3. Several plastic curtains 4 are installed on both the inlet and outlet ports of the drying chamber 2. The plastic curtains 4 are used to seal the drying chamber 2. Several clips 5 are arranged along the vertical edges of the plastic curtains 4, and magnets 6 are installed inside the clips 5. The vertical edges of adjacent plastic curtains 4 are attracted by the magnets 6. The magnets 6 are installed on the plastic curtains 4 by the clips 5, closing the adjacent plastic curtains 4 together, thus forming a sealed space in the drying chamber 2, reducing heat loss. Its sealing structure is simple, and the electrophoretic workpieces 3 can easily enter and exit the curtains.

[0024] In this embodiment, as Figure 1 and 3 As shown, the lifting device includes a lifting rod 7, a crossbeam 8, and clamping components. The crossbeam 8 is suspended on the lifting rail 1 by the lifting rod 7, which is located at the center of the crossbeam 8. The clamping components are installed on the crossbeam 8 to clamp the workpiece 3. A curtain-breaking rod 9 is also fixed on the crossbeam 8. The curtain-breaking rod 9 is V-shaped, with the two ends of the V-shape fixed to the two ends of the crossbeam 8. The curtain-breaking rod 9 is located in front of the crossbeam 8 in the direction of travel. The curtain-breaking rod 9 is used to lift the curtain to prevent the curtain from scratching the workpiece 3 after electrophoresis, which would cause the wet paint to be scratched and result in defective products.

[0025] In this embodiment, as Figure 3 and 4 As shown, two through slots 10 are provided on the crossbeam 8. The two through slots 10 are located at both ends of the crossbeam 8. The cross-section of the through slot 10 is an isosceles trapezoidal shape, with the small end of the through slot 10 facing the ground. The clamping component consists of two wedge-shaped nylon blocks 11. The inclined surface of the clamping component fits with the waistline of the isosceles trapezoid. The workpiece 3 is clamped by the two nylon blocks 11. The nylon blocks 11 clamp the electrophoretic workpiece 3, avoiding the use of hooks and drilling holes in the workpiece 3, which would affect the overall performance of the workpiece. At the same time, the combination of the isosceles trapezoidal and wedge-shaped structures makes the clamped electrophoretic workpiece 3 clamp tighter and tighter under the action of gravity, reducing the risk of falling off during the conveying process and causing damage to the electrophoretic workpiece 3.

[0026] In this embodiment, as Figure 4 As shown, a number of protrusions 12 arranged in a matrix are fixed on the clamping surface of the nylon block 11. The protrusions 12 are hemispherical and are clamped by point-to-surface contact, which reduces the area of ​​obstruction on the electrophoretic part and causes dot-like defects to be formed after electrophoresis, so as to keep the defects within the allowable range and avoid subsequent touch-up painting.

[0027] In this embodiment, as Figure 1As shown, the side wall of the drying oven 2 is a hollow structure, and the side wall is filled with heat insulation cotton. The hot air inlet of the drying oven 2 is located at the bottom of the drying oven 2, which further reduces heat loss. At the same time, it uses the natural principle of hot air rising to dry the workpiece 3, avoiding the problem of uneven heating of the workpiece 3 caused by air entering from the top and not sinking, which would affect the drying quality.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
