DETAILED DESCRIPTION

[0024] The present invention provides Figure 1-Figure 6 The invention discloses an environmentally friendly plastic electroplating device and process for the surface of a highly wear-resistant injection-molded panel.

[0025] 1. Surface treatment: Before electroplating, plastic products need to be surface treated to ensure that the surface is clean, smooth and free of oil stains; Surface treatment usually includes steps such as degreasing, dust removal, cleaning and roughening.

[0026] Among them, degreasing refers to the use of solvents or alkaline cleaning agents to remove oil and dirt from the surface of plastic products; Dust removal refers to the use of air or mechanical equipment to remove dust and impurities from the plastic surface; Cleaning refers to cleaning the surface of plastic products with cleaning fluid or cleaning equipment to remove residual oil and dirt; Roughening treatment refers to the use of chemical liquids or mechanical equipment to make micro-contact changes to the plastic surface to increase surface adhesion and improve the adhesion of the electroplating layer.

[0027] 2. Chemical plating pretreatment: After the plastic surface treatment is completed, chemical plating pre-treatment is required to enhance the bonding strength between the plastic surface and the metal electroplating layer.

[0028] Chemical plating pre-treatment generally includes activation treatment, pre-plating activation treatment and chemical plating pre-treatment.

[0029] Among them, active treatment refers to the use of chemical liquid or physical methods to activate the plastic surface to increase surface activity and improve the adhesion of the coating; Activation treatment before plating refers to the use of acidic or alkaline solutions to activate the plastic surface to enhance the adhesion of the coating; Chemical plating pretreatment refers to the use of chemical liquid to treat the plastic surface to enhance the adhesion and corrosion resistance of the coating.

[0030] 3. Electroplating: After the chemical plating pre-treatment is completed, the electroplating process begins. Electroplating refers to the use of electrolyte and electric current to coat the plastic surface with metal.

[0031] Electroplating usually includes pre-plating treatment, electroplating, and post-plating treatment.

[0032] Among them, pre-plating treatment refers to the use of chemical liquid to treat the plastic surface to enhance the adhesion and corrosion resistance of the coating; Electroplating refers to immersing plastic products in an electrolytic tank and using electric current and electrolyte to apply metal plating to the plastic surface; post-plating treatment refers to using chemical liquid to treat the electroplated plastic products to enhance the anti-oxidation and corrosion resistance of the coating.

[0033] 4. Post-treatment of chemical plating: After electroplating is completed, chemical post-plating treatment is required to enhance the oxidation resistance and corrosion resistance of the electroplating layer.

[0034] Post-chemical plating processing usually includes steps such as cleaning, sealing, polishing and packaging.

[0035] Among them, cleaning refers to cleaning the electroplated plastic products with cleaning fluid to remove residual chemical fluids and impurities; Sealing refers to the use of chemical liquid or sealing agent to seal the electroplating layer to enhance its antioxidant and corrosion resistance; Polishing refers to the use of polishing equipment to polish the electroplating layer to make its surface smooth and uniform; Packaging refers to packaging electroplated plastic products to protect their surface gloss and anti-corrosion properties.

[0036] In summary, plastic electroplating is a common surface treatment process, which can make the surface of plastic products have metallic luster and anti-corrosion properties, improve their appearance and service life. The plastic electroplating process mainly includes surface treatment, chemical plating pre-treatment, electroplating, chemical plating post-treatment and other links.

[0037] However, the existing technology: the environmentally friendly plastic electroplating process on the surface of high-wear-resistant injection molding panels (patent application number 202210920445.6) usually uses chemical liquids or mechanical equipment to make micro-touch changes to the plastic surface during the roughening treatment of the surface treatment, thereby increasing the surface adhesion and improving the adhesion of the electroplating layer; for example: the existing patent uses a flat plastic panel placed in a pressing mold for pressing, and spraying low-temperature plasma during the pressing process to produce a number of pits on the surface of the plastic panel to increase the surface adhesion.

[0038] This method also requires spraying low-temperature plasma such as Ar plasma to produce polar groups on the surface of the plastic panel to improve the hydrophilicity of the plastic material surface. Subsequent steps such as catalysis, degumming, and coating are required, which is inefficient and increases costs.

[0039] Therefore, reference Figure 1 As shown in the present invention, a highly wear-resistant injection-molded panel surface environmentally friendly plastic electroplating process is proposed, including: roughening and cleaning, chemical plating pre-treatment, electroplating and chemical plating post-treatment; Among them, the roughening cleaning is carried out by the roughening cleaning mechanism, which integrates degreasing, dust removal, primary cleaning, roughening treatment and secondary cleaning in one process, replacing the method of degreasing, dust removal, cleaning and roughening treatment of plastic panels separately, improving processing efficiency and reducing production costs. It eliminates the need to use low-temperature plasma spraying.

[0040] Specific: Reference Figure 1 As shown in The first step: roughening cleaning, which includes using a roughening cleaning mechanism to remove oil, dust, primary cleaning, roughening treatment, and secondary cleaning of the plastic panel; The second step: chemical plating pre-treatment, chemical plating pre-treatment includes activation treatment, pre-plating activation treatment and chemical plating pre-treatment; The third step: electroplating. After the chemical plating pre-treatment is completed, the electroplating process begins, using electrolyte and current to perform metal plating on the plastic surface; Step 4: Chemical plating post-treatment. After electroplating is completed, chemical plating post-treatment is carried out. Chemical plating post-treatment includes cleaning, sealing, polishing and packaging.

[0041] refer to Figure 2As shown in the figure, the roughening cleaning mechanism includes a lower support plate 2, below which are sequentially arranged a first nozzle 9, a first plastic brush 8, a second nozzle 7, a steel brush 6, and a second plastic brush 5, wherein the third nozzle 4 is interspersed among the bristles of the second plastic brush 5.

[0042] The first nozzle 9 is used to spray a solvent or an alkaline cleaning agent to clean the oil and dirt on the surface of the plastic panel 21; The first plastic brush 8 is used to clean the dust and impurities on the surface of the plastic panel 21; The second nozzle 7 is used to spray cleaning liquid to clean the surface of the plastic panel 21 to remove residual oil and dirt; The steel brush 6 is used to contact the surface of the plastic panel 21, so as to form a rough surface 22 on the surface of the plastic panel 21 by scraping; The second plastic brush 5 is used to clean the dust and impurities on the surface of the rough surface 22; while cleaning the dust and impurities, the third nozzle 4 sprays the cleaning liquid to assist in cleaning the dust and impurities.

[0043] The specific process of treating the surface of the plastic panel 21 is as follows: The plastic panel 21 and the lower support plate 2 are made to move relative to each other, and the lower support plate 2 or the plastic panel 21 moves along the length direction of the plastic panel 21 or the lower support plate 2 respectively, so that the first plastic brush 8, the steel brush 6, and the second plastic brush 5 contact the surface of the plastic panel 21. If the plastic panel 21 moves relative to the lower support plate 2, the plastic panel 21 moves from the position of the first plastic brush 8 to the position of the second plastic brush 5. The first plastic brush 8, the second nozzle 7, the steel brush 6, the second plastic brush 5, and the third nozzle 4 can be used respectively to complete degreasing, dust removal, primary cleaning, roughening treatment, and secondary cleaning.

[0044] It should be noted that the plastic panel 21 may be moved by a conveyor line, or the lower support plate 2 may be moved by an electric push rod, an electric cylinder, a chain transmission, etc., which is not limited here.

[0045] refer to Figure 3 As shown in , it is a schematic diagram of the roughening and cleaning mechanism processing the plastic panel 21 and forming a rough surface 22 on the surface of the plastic panel 21.

[0046] refer to Figure 2 and Figure 3As shown in the figure, considering that the surface of the plastic panel 21 needs to be processed with rough surfaces 22 of different depths for different processing requirements, an airbag 3 is fixedly arranged on the lower surface of the lower support plate 2. The airbag 3 is an inflatable airbag structure and is rectangular as a whole. When the airbag 3 is inflated, the airbag 3 expands and drives the first plastic brush 8, the steel brush 6 and the second plastic brush 5 to rise and fall to a certain extent, thereby adjusting the processing depth of the rough surface 22.

[0047] Furthermore, during the processing, the airbag 3 itself has a certain elastic expansion and contraction ability, so that the steel brush 6 can always scratch the surface of the plastic panel 21 with appropriate force, and there will be no phenomenon that the steel brush 6 scratches the plastic panel 21 excessively due to vibration during the transmission process of the mechanical equipment.

[0048] refer to Figure 3 As shown in , an inflation pipe 15 is fixedly provided on the upper surface of the lower support plate 2 , and an air pump or other device is connected to the inflation pipe 15 to inflate the airbag 3 .

[0049] refer to Figure 4 As shown in FIG. 1 , in the present invention, a pressure sensor 19 is fixedly installed inside the airbag 3 , and the pressure sensor 19 is used to monitor the gas pressure inside the airbag 3 .

[0050] Based on the setting of the pressure sensor 19, on the one hand, the gas pressure in the airbag 3 can be monitored to determine the degree of regulation; on the other hand, whether an abnormal situation occurs can be determined by real-time monitoring of the gas pressure in the airbag 3.

[0051] For example, if an electrical box is installed, a controller is provided in the electrical box, and the controller can feed back real-time gas pressure data to a tablet computer or other terminal. If the gas pressure data fluctuates abnormally, it proves that the airbag 3 is severely compressed or loosened, which also indicates that there may be bulges on the surface of the plastic panel 21 or the equipment is bumpy or stuck. The rough surface 22 of the plastic panel 21 is very likely to be unqualified. At this time, the terminal feeds back to the staff, and the staff can solve the problem or remove defective products in time, which is more convenient.

[0052] A spring 17 is provided in the airbag 3, and connection pads 18 are fixedly connected to both ends of the spring 17. The connection pads 18 are bonded and fixed to the inner wall of the airbag 3. The spring 17 is vertically arranged, and there are multiple springs 17. The spring 17 plays the role of pulling the airbag 3, so that when the gas in the airbag 3 is released, the airbag 3 can be reset.

[0053] The airbag 3 is rectangular in shape and can be raised and lowered evenly in height when the airbag 3 expands or contracts, so that the bottom heights of the first plastic brush 8 , the steel brush 6 and the second plastic brush 5 remain the same, so as to evenly process the surface of the plastic panel 21 to form a rough surface 22 .

[0054] refer to Figure 2 and Figure 4 As shown in the figure, a sealing sleeve 16 is integrally provided on the inner wall of the airbag 3, and the sealing sleeve 16 allows the third nozzle 4, the second nozzle 7, and the first nozzle 9 to move through. When the airbag 3 expands or contracts, it also deforms along the third nozzle 4, the second nozzle 7 or the first nozzle 9, and can play a certain guiding role, so that it maintains a rectangular shape and expands evenly.

[0055] Furthermore, the second plastic brush 5, the steel brush 6, and the first plastic brush 8 are attached to the lower surface of the airbag 3 in the form of an adhesive plate 10, which is convenient for replacement and maintenance.

[0056] An upper support plate 1 is arranged above the lower support plate 2, and a third concentration box 12, a second concentration box 13 and a first concentration box 14 are arranged in sequence above the upper support plate 1. External pipes are arranged in the third concentration box 12, the second concentration box 13 and the first concentration box 14. The external pipes on the third concentration box 12 and the second concentration box 13 are for external cleaning liquid to enter, and the external pipe on the first concentration box 14 is for external solvent or alkaline cleaning agent to enter. A plurality of third nozzles 4, second nozzles 7 and first nozzles 9 are arranged, and a plurality of third nozzles 4 are connected to the lower end of the third concentration box 12, a plurality of second nozzles 7 are connected to the lower end of the second concentration box 13, and a plurality of first nozzles 9 are connected to the lower end of the first concentration box 14.

[0057] refer to Figure 2 As shown in the figure, the present invention is also provided with an electric cylinder 11 at the bottom of the upper support plate 1. The electric cylinder 11 is vertically arranged, and the lower end of the electric cylinder 11 is connected to the upper surface of the lower support plate 2. When working, the electric cylinder 11 is started to move the upper support plate 1 relative to the lower support plate 2, thereby adjusting the height positions of the third nozzle 4, the second nozzle 7, and the first nozzle 9, which is convenient for adjusting the cleaning effect.

[0058] Furthermore, since the outer circles of the lower ends of the third nozzle 4, the second nozzle 7 and the first nozzle 9 are connected to the limiting ring 20 by threaded cooperation, the limiting ring 20 can play a limiting role, which can prevent the third nozzle 4, the second nozzle 7 and the first nozzle 9 from being excessively separated from the corresponding sealing sleeve 16 when adjusting the height of the third nozzle 4, the second nozzle 7 and the first nozzle 9; the depth of the steel brush 6 scratching the plastic panel 21 can also be limited by adjusting the position of the limiting ring 20 away from the lower end of the second plastic brush 5, which is highly practical.
