Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plastic parts, and more specifically, to a high-flow flat-edge process for plastic parts. Background Art
[0002] High flow leveling of plastic parts is to volatilize the solvent volatilization gas on the surface of the wet paint workpiece within a certain period of time. While the volatilization gas volatilizes, the wet paint film also levels, thus ensuring the flatness and gloss of the paint film. In the wet-on-wet process, flow leveling also plays a role in surface drying. However, in the existing high-flow flat-edge process for plastic parts during the NCVM processing step, there is often a large amount of oil accumulated on the surface of the plastic parts, which will affect the subsequent processing. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the present invention provides a high-flow flat-edge process for plastic parts, which has the advantage of preventing oil accumulation from occurring during the NCVM processing step.
[0004] To achieve the above object, the present invention provides the following technical solution: A high-flow flat-edge process for plastic parts, including raw materials. The raw materials need to be surface-treated through grinding, painting, and NCVM processes, so as to make the surface of the plastic parts smoother. The painting equipment contains a drying device and a ventilation device, and its specific usage steps are as follows:
[0005] S1: Place the raw materials on the workbench for grinding to make the surface of the raw materials smooth;
[0006] S2: After grinding, spray a layer of treatment agent on the surface of the raw materials;
[0007] S3: When the spraying of the treatment agent is completed and the surface of the raw materials is dry, spray the primer on the surface layer of the raw materials;
[0008] S4: After the primer is sprayed, place the raw materials inside the drying device for drying, and at the same time, the ventilation device ventilates the surface of the raw materials to make the primer have a quick-drying effect;
[0009] S5: The detection device detects the spraying situation of the primer. When the detection is qualified, it smoothly enters the next process. At the same time, when the detection is unqualified, it returns to the step of spraying the primer for secondary spraying;
[0010] S6: Process the raw materials with qualified primer spraying through the NCVM process. At this time, because the surface of the raw materials is smooth and protected by the primer, during the NCVM process, less oil will accumulate;
[0011] S7: Next, the raw materials processed by the NCVM process are sprayed with intermediate paint. After the spraying is completed, the sprayed intermediate paint is inspected. If it is qualified, the next process is carried out; if it is unqualified, secondary treatment is carried out.
[0012] S8: The raw materials sprayed with intermediate paint are subjected to topcoat spraying treatment, and at the same time, the sprayed topcoat is inspected.
[0013] S9: The plastic parts with qualified topcoat spraying are subjected to edge treatment. The TP / BP surface and CNCC edges of the plastic parts are processed by a grinding device to make the edges of the plastic parts smoother.
[0014] S10: Finally, the plastic parts are subjected to secondary topcoat spraying.
[0015] As a preferred technical solution of the present invention, the grinding process will first grind the raw materials. The accuracy of the grinding ensures the flatness of the surface of the raw materials. After the grinding is completed, the smoothness of the ground surface is inspected. Only after passing the inspection can the next process be carried out.
[0016] As a preferred technical solution of the present invention, the treatment agent is sprayed on the surface of the raw materials after the raw materials are ground, so as to form a protective film on the surface of the raw materials while treating the surface of the raw materials, improving the subsequent treatment effect.
[0017] As a preferred technical solution of the present invention, the primer is sprayed on the raw materials through equipment after the surface of the raw materials is dried after passing through the treatment agent, which can effectively lay a good bottom layer foundation. At the same time, because it has been treated by the treatment agent, the primer spraying is also more convenient. After spraying the primer, the plastic parts are dried by a drying device, and then the air circulation is increased through a ventilation device to improve the drying efficiency of the primer.
[0018] As a preferred technical solution of the present invention, after the primer spraying is completed, the NCVM process is carried out to form a thin film on the surface of the plastic parts, which has excellent wear resistance, corrosion resistance, uniform coating thickness, high density, etc.
[0019] As a preferred technical solution of the present invention, after the NCVM process treatment is completed, the intermediate paint is sprayed on the surface of the plastic parts, so that the thin film generated by the NCVM process treatment is sandwiched between the intermediate paint and the primer, thereby achieving the effect of protecting the thin film.
[0020] As a preferred technical solution of the present invention, the plastic parts with qualified intermediate paint spraying are subjected to topcoat spraying treatment, and the topcoat can be changed to different colors to make the plastic parts form the required color and improve the overall aesthetics.
[0021] As a preferred technical solution of the present invention, the plastic parts with qualified topcoat spraying are subjected to corner edge grinding treatment. The corner edges and TP / BP surfaces of the plastic parts are processed by a grinding device to make them look more natural.
[0022] As a preferred technical solution of the present invention, after the TP / BP surface and CNCC corner edge treatment are completed, since a lot of topcoat will be ground off during the grinding process, secondary topcoat treatment is required. At the same time, drying equipment and ventilation equipment are used to quickly dry the secondary topcoat, so that the topcoat spraying is completed. At the same time, the surface is treated after inspection.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] 1. In the present invention, by spraying the primer, after the raw material is treated with a treating agent and its surface is dried, the raw material is sprayed with the primer by equipment, which can effectively lay a good bottom layer foundation. At the same time, due to being treated with the treating agent, the primer spraying is also more convenient. After spraying the primer, the plastic parts are dried by drying equipment, and then the air circulation is increased by ventilation equipment to improve the drying efficiency of the primer. At the same time, during the ordinary NCVM process treatment, a lot of oil accumulation will form on its surface, and these oil accumulations need to be treated by specific processes, which is troublesome. However, in the present invention, since a layer of primer is sprayed on the plastic parts before the NCVM process treatment, its surface becomes smooth, so that the situation of oil accumulation will not occur.
[0025] 2. In the present invention, the raw material is polished smoothly during processing, and at the same time, primer, intermediate paint and topcoat are sprayed in the subsequent processing, making its surface clean. At the same time, a protective film is formed on its surface, and when spraying the primer, intermediate paint and topcoat, accurate detection is carried out to ensure the uniform spraying effect on each surface. When the TP / BP surface and CNCC corner edge treatment are carried out, since the surface is originally smooth, the trouble of defects on the TP and BP surfaces is solved during grinding, and the CNC post-processing is used to remove the defective effects after NCVM.

[0026] Figure 1 It is a schematic structural diagram of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] Such asFigure 1 As shown, the present invention provides a high-flow straight-edge process for plastic parts, including raw materials. The raw materials need to be surface-treated through grinding, painting, and NCVM processes, so as to make the surface of the plastic parts smoother. The painting equipment includes a drying device and a ventilation device, and the specific usage steps are as follows:
[0029] S1: Place the raw materials on the workbench for grinding to make the surface of the raw materials smooth;
[0030] S2: After grinding, spray a layer of treatment agent on the surface of the raw materials;
[0031] S3: When the treatment agent is sprayed and the surface of the raw materials is dry, spray the primer on the surface layer of the raw materials;
[0032] S4: After the primer is sprayed, place the raw materials inside the drying device for drying. At the same time, the ventilation device ventilates the surface of the raw materials to make the primer have a quick-drying effect;
[0033] S5: The detection device detects the spraying situation of the primer. When the detection is qualified, it smoothly enters the next process. At the same time, when the detection is unqualified, it returns to the step of spraying the primer for secondary spraying;
[0034] S6: Process the raw materials with qualified primer through the NCVM process. At this time, because the surface of the raw materials is smooth and protected by the primer, less oil accumulation will occur during the NCVM process;
[0035] S7: Secondly, spray the intermediate paint on the raw materials processed through the NCVM process. After spraying, detect the sprayed intermediate paint. If it is qualified, proceed to the next process. If it is unqualified, perform secondary treatment;
[0036] S8: Spray the topcoat on the raw materials with the intermediate paint sprayed, and at the same time detect the sprayed topcoat;
[0037] S9: Dispose of the corners of the plastic parts with qualified topcoat sprayed. Use a grinding device to process the TP / BP surface and CNCC corners of the plastic parts to make the corners of the plastic parts smoother;
[0038] S10: Finally, perform secondary topcoat spraying on the plastic parts.
[0039] The raw materials are cyclically processed through multiple detections, which timely reduces the situation of defective products during the processing of the raw materials and ensures the stability of the product during the production process.
[0040] Among them, the grinding process will first grind the raw materials. The accuracy of grinding ensures the flatness of the surface of the raw materials. After grinding is completed, the smoothness of the ground surface is detected, and only after passing the inspection can the next process be carried out.
[0041] The grinding process ensures the overall smoothness of the raw materials, facilitating the processing of subsequent processing steps, thus laying a foundation for the overall processing.
[0042] Among them, the treatment agent is sprayed on the surface of the raw materials after the raw materials are ground, so as to form a protective film on the surface of the raw materials while treating the surface of the raw materials, improving the subsequent treatment effect.
[0043] After being treated with the treatment agent, it can effectively prevent more burrs from appearing on the surface of the raw materials, improving the smoothness of the surface of the raw materials.
[0044] Among them, after the raw materials are treated with the treatment agent and their surfaces are dried, the primer is sprayed on the raw materials through equipment. This can effectively lay a good foundation for the bottom layer. At the same time, because the raw materials have been treated with the treatment agent, the primer spraying is also more convenient. After spraying the primer, the plastic parts are dried through a drying device, and then the air circulation is increased through a ventilation device to improve the drying efficiency of the primer.
[0045] After the primer is sprayed, the detection equipment will detect the primer on the surface of the plastic parts. When the thickness of the primer is inconsistent, it will be returned to the primer spraying equipment for re-spraying, so as to ensure the uniform surface of the primer.
[0046] Among them, after the primer is sprayed, the NCVM process is carried out to form a thin film on the surface of the plastic parts, which has excellent wear resistance, corrosion resistance, uniform coating thickness, high density, etc.
[0047] During the normal NCVM process, more oil accumulation will form on its surface, and these oil accumulations need to be processed by specific processes, which is troublesome. However, in the present invention, since a layer of primer is sprayed on the plastic parts before the NCVM process, the surface becomes smooth, so that the situation of oil accumulation will not occur.
[0048] Among them, after the NCVM process is completed, the intermediate paint is sprayed on the surface of the plastic parts, so that the thin film generated by the NCVM process is sandwiched between the intermediate paint and the primer, so as to achieve the effect of protecting the thin film.
[0049] After the intermediate paint is sprayed, the required steps are the same as those of the primer. It needs to be inspected and qualified before it can enter the next process to prevent the situation of inconsistent spraying of the intermediate paint.
[0050] Among them, the plastic parts with qualified intermediate paint spraying are subjected to topcoat spraying treatment. The topcoat can be changed to different colors to make the plastic parts form the required color and improve the overall aesthetics.
[0051] The topcoat is the color finally presented and can be combined in multiple colors. Therefore, the requirements for the spraying process are relatively high. Therefore, it is necessary to carefully inspect the topcoat to prevent the appearance of defective products.
[0052] Among them, the plastic parts with qualified topcoat spraying are subjected to corner edge grinding treatment. The corner edges and TP / BP surfaces of the plastic parts are processed by a grinding device to make them look more natural.
[0053] Corner edge treatment can make the overall plastic part appear smoother and more natural, facilitating subsequent normal installation.
[0054] Among them, after the TP / BP surface and CNCC corner edge treatment are completed, since a lot of the topcoat will be ground off during the grinding process, a secondary topcoat treatment is required. At the same time, drying equipment and ventilation equipment quickly dry the secondary topcoat to complete the topcoat spraying. At the same time, the surface is treated after inspection.
[0055] Surface treatment mainly targets dust on the outside of the plastic part, etc., to ensure that the surface of the plastic part feels convenient for subsequent storage.
[0056] The working principle and usage process of the present invention:
[0057] First, the raw materials are ground to make the surface of the raw materials smoother and keep the overall thickness of the materials consistent;
[0058] Secondly, after grinding, a layer of treatment agent is sprayed on the surface of the raw materials to slightly treat the traces of grinding on the surface and prevent the residue of grinding dust at the same time;
[0059] At this time, after the treatment agent is sprayed, a layer of primer is sprayed on the surface of the raw materials to make the surface smoother and flatter. At the same time, after spraying, the primer is quickly dried by drying and ventilation equipment to improve the processing efficiency and facilitate subsequent processing. At the same time, the sprayed primer is inspected to prevent unqualified situations;
[0060] At the same time, after the primer is sprayed, NCVM process treatment is carried out to form a thin film on the surface of the plastic part, making it have excellent wear resistance, corrosion resistance, uniform coating thickness, high density, etc. And in the usual NCVM process treatment, more oil accumulation will form on its surface, and these oil accumulations need to be treated by a specific process, which is troublesome to operate. However, in the present invention, since a layer of primer is sprayed on the plastic part before the NCVM process treatment, the surface becomes smooth, so that the situation of oil accumulation will not occur;
[0061] At this time, a primer and a topcoat are sprayed on the surface of the raw material, and the topcoat can be sprayed in the desired color. After spraying, the TP / BP surface and the CNCC corner edges are repaired to make them smoother without any defects.
[0062] Finally, after the treatment of the TP / BP surface and the CNCC corner edges is completed, since a lot of the topcoat is polished off during the polishing process, a second topcoat treatment is required. At the same time, the drying equipment and the ventilation equipment quickly dry the second topcoat to complete the topcoat spraying. After the detection is completed, the surface is treated to ensure that the surface of the plastic part feels convenient for subsequent storage.
