Description

Technical Field

[0001] The invention belongs to the field of spraying technology, in particular to an automatic spraying and forming device for a thermal insulation coating on the surface of a special-shaped part. Background Art

[0002] Polyurethane foam materials offer excellent thermal insulation, waterproofing, sound absorption, shock absorption, adhesion, and chemical stability. These advantages have made rigid polyurethane foam materials irreplaceable in aerospace equipment, defense weaponry, energy equipment, and other fields. Mold-cast foaming and spray-foaming are two relatively early and widely used polyurethane foam molding processes. Compared to mold-cast foaming, spray-foaming offers advantages such as shorter production cycles, lower foam loss, lower production costs, and lower labor intensity for creating rigid polyurethane foam insulation layers on surfaces with complex structures, large surface contours, and numerous irregularly shaped components. The resulting foam is highly integrated, consistent, and seamless, adhering tightly to the surface it is applied to, providing excellent thermal insulation. However, most current automated spray-coating systems for insulating irregularly shaped parts do not perform further pretreatment on the parts before they are transported to the spray chamber. Any impurities adhering to the surface during transport can negatively impact the subsequent spray coating. Summary of the Invention

When the power gear 721 is running, it drives the second support platform 72 to rotate. At this time, the first support platform 71 also rotates, and causes the matching gear to rotate, which can better ensure the stability of the support platform.

[0041] The pre-treatment component 8 includes a lifting member 81 and a pre-treatment member 82 arranged on the lifting member 81. The lifting member 81 includes a lifting screw. The bottom end of the lifting screw is installed on the output end of the lifting motor, and the top end is rotatably connected to the translation component 711 arranged on the first support platform 71. The bottom of the lifting motor is installed with a sliding member 723. The sliding member 723 is slidably connected to the slide groove 722 arranged on the second support platform 72. The horizontal sliding direction and range of the sliding member 723 in the slide groove 722 are consistent with the moving direction and range of the lifting screw on the translation component 711; the lifting screw is threaded with a lifting nut 811.

After cleaning, the translation component 711 drives the pretreatment component 82 out of the cleaning box 91, and the lifting screw drives the pretreatment component 82 down to the position corresponding to the drying box 92. The translation component 711 then drives the pretreatment component 82 into the drying box 92. During this process, the other pretreatment component 82 cleans the surface of the special-shaped parts in the first processing chamber 41.

In conjunction with the rotating cleaning brush 911-2, the pretreatment drum 821 can be effectively cleaned, and the generated cleaning waste water is also discharged from the cleaning box 91 through the drain pipe 912. An arc-shaped drainage surface is provided on the surface of the connecting frame 822 to avoid accumulation of water generated by cleaning.

[0045] The water tank 911-4 includes a box body and a filter layer. The filter layer divides the box body into a sewage chamber and a filter chamber provided in an upper and lower position. The drain pipe 912 extends into the sewage chamber, and the pumping end of the water pump 911-3 extends into the filter chamber.

When the spraying robot arm automatically sprays the workpiece, the stainless steel environmentally friendly water curtain cabinet provides a clean and clear spraying space for the equipment. The environmentally friendly water curtain cabinet has its own filtering function. The operator only needs to add water and clean up waste regularly.

[0048] The implementation principle of the present invention is as follows: the special-shaped parts are placed on the rotating tooling 21. As the circular assembly line 2 runs, the special-shaped parts and the rotating tooling 21 first enter the first treatment chamber 41. The pretreatment part 82 can perform the first pretreatment on the surface of the special-shaped parts. After completing the first pretreatment, the special-shaped parts enter the second treatment chamber 42 and then complete the second pretreatment to enter the drying chamber 3 to be heated to an appropriate temperature before entering the spraying chamber 1. The spraying robot arm in the spraying chamber 1 sprays the surface of the rotating special-shaped parts. During the spraying process, the suction pump circulates and draws water evenly onto the water curtain plate, so that the exhaust gas (waste material) sprayed out of the spray gun is hit by the water on the water curtain plate into the water pool below, and then a small part of the exhaust gas (waste material) is discharged outside the workshop through the exhaust duct by the fan above. After the spraying is completed, the special-shaped parts are transmitted from the outlet of the spraying chamber 1 to the unloading area.
