[0064] Second embodiment

[0065] Please refer to Figure 5 Based on the conveying structure provided by the first embodiment of the application, the second embodiment of the application provides another conveying structure. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment.

[0066] Specifically, the conveying structure provided by the second embodiment of the application is different from the first embodiment in that the conveying structure is provided with a dismounting assembly 7 on the top of the hydraulic telescopic piece 52, the dismounting assembly 7 comprises a dismounting sleeve 71, a dismounting block 72 and a fixing pin 73, the dismounting block 72 is connected to the inside of the dismounting sleeve 71 through plug-in connection, the dismounting sleeve 71 is connected to the bottom of the second gear 43, and the fixing pin 73 is arranged between the dismounting sleeve 71 and the dismounting block 72.

[0067] A fixing through hole matched with the fixing pin 73 is formed between the dismounting sleeve 71 and the dismounting block 72, and the dismounting block 72 is connected to the top of the hydraulic telescopic piece 52.

[0070] Compared with the related art, the conveying structure provided by the application has the following beneficial effects:

[0071] The dismounting sleeve 71, the dismounting block 72 and the fixing pin 73 arranged between the hydraulic telescopic piece 51 and the second gear 43 can replace the suspension assembly 6 according to different automobile accessories.

[0072] Please refer to Figure 6, based on the first embodiment of the present application provides a kind of overall painting workshop, the third embodiment of the present application proposes another overall painting workshop.The third embodiment is only the preferred mode of the first embodiment, and the implementation of the third embodiment does not affect the separate implementation of the first embodiment.

[0073] Specifically, the third embodiment of the present application provides an overall painting workshop, which differs from the first embodiment in that an overall painting workshop, as described above, includes a pretreatment device, a painting device, and a drying and curing device.

[0074] The pretreatment device includes a degreasing device, a water washing device, and a phosphating device.

[0075] The painting device includes a spraying device and a paint supply system.

[0076] The degreasing device includes a degreasing tank, a heating device, and a stirring device. The degreasing tank is used to hold a degreasing agent. The heating device controls the temperature of the degreasing liquid. The stirring device ensures uniformity of the degreasing liquid, effectively removing oil and dirt from the surface of the automobile parts. For example, a common spray-type degreasing device can quickly degrease the parts.

[0077] The water washing device includes multiple water washing tanks and a spray washing device. The water washing tanks are used to soak and clean the parts. The spray washing device can wash the parts with high-pressure water flow to remove the degreasing agent and impurities. Multiple stages of water washing can gradually reduce the residue of pollutants on the surface of the parts, ensuring cleanliness.

[0078] The phosphating device includes a phosphating tank, a temperature control system, and a slag removal device. The phosphating liquid in the phosphating tank reacts with the surface of the parts at a certain temperature to form a phosphating film, enhancing the adhesion of the coating and corrosion resistance. The slag removal device timely removes the slag generated during the phosphating process, ensuring the quality of phosphating.

[0079] The spraying device includes air spraying equipment, electrostatic spraying equipment, and powder spraying equipment. The air spraying equipment uses compressed air to atomize and spray paint onto the surface of the parts. The electrostatic spraying equipment charges the paint, which is attracted to the parts under the action of the electric field, improving paint utilization and coating uniformity. The powder spraying equipment sprays powder paint onto the surface of the parts through a spray gun, and the coating is formed after heating and curing. It is commonly used for painting automobile hubs and other parts.

[0080] The paint supply system is composed of a paint storage tank, a paint conveying pipeline, a filter, and a metering pump. The paint storage tank stores paint. The paint conveying pipeline is responsible for conveying paint. The filter filters impurities. The metering pump accurately controls the amount of paint delivered, ensuring stable supply of paint during spraying.

[0081] The drying and curing device includes a drying furnace, a curing furnace, and a conveying device.

[0082] Drying oven: Commonly used are hot air circulation drying oven and infrared drying oven. The hot air circulation drying oven circulates hot air in the oven through a fan to uniformly heat the accessories and remove moisture. The infrared drying oven uses infrared radiation to heat the accessories, which has fast heating and high efficiency, and is suitable for rapid drying of coatings.

[0083] Curing oven: Different temperatures and times are set according to the type of paint to make the paint cure into a film. For example, a powder coating curing oven needs to accurately control the temperature and time to ensure that the powder fully melts, levels, and cures to form a high-quality coating.

[0084] Conveying equipment: Includes suspended conveying chain, ground chain plate conveying line, and roller conveyor. The suspended conveying chain can suspend and convey accessories, suitable for continuous coating of accessories of various shapes. The ground chain plate conveying line has strong carrying capacity and is suitable for conveying heavy accessories. The roller conveyor is commonly used for conveying planar accessories, facilitating the flow of accessories between different processes.

[0085] Degreasing: The automotive accessories are immersed in a degreasing tank or sprayed with a degreasing agent to remove surface grease.

[0086] Water washing: Multiple water washing is performed, first by immersion and then by spraying, to gradually remove residual degreasing agents and impurities on the surface of the accessories.

[0087] Phosphating: The accessories are placed in a phosphating tank for phosphating treatment to form a phosphating film on the surface of the accessories.

[0088] Primer spraying: According to the material and requirements of the accessories, appropriate primer is selected for spraying, such as cathodic electrophoretic primer. The electrophoretic coating process can be used to make the primer evenly adhere to the surface of the accessories, improving the corrosion resistance.

[0089] Middle coating and color paint spraying: After the primer is dried, middle coating is sprayed to increase the thickness and fullness of the coating, and then color paint is sprayed to give the accessories the desired color and appearance. Each layer of paint needs to be properly dried after spraying, and the drying time depends on the type and thickness of the paint.

[0090] Clear paint spraying: After the color paint is dried, clear paint is sprayed to improve the gloss, hardness, and weather resistance of the coating, enhancing the protective performance of the surface of the accessories

[0091] Drying and curing stage: The coated accessories are sent to the drying oven or curing oven through the conveying equipment, and the temperature and time are controlled according to the curing process requirements of the paint.

[0092] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
