Description

Technical Field

[0001] This utility model relates to the field of chemical coating technology, and in particular to a chemical coating device for mobile phone displays. Background Technology

[0002] The main purpose of chemical coating on mobile phone displays is to significantly improve their optical performance, durability, and user experience by depositing functional thin films (such as anti-fingerprint AF film, anti-reflective AR film, or anti-glare AG film) on the surface. Chemical coating can form a uniform nanoscale coating, effectively reducing fingerprint residue, reducing screen reflection, and enhancing light transmittance. At the same time, it can improve wear resistance and corrosion resistance, extend the life of the display, and meet diverse needs such as high-definition display, touch sensitivity, and outdoor visibility.

[0003] Currently, existing chemical coating equipment for mobile phone displays typically only has basic coating functions. Although it can complete the chemical coating operation on mobile phone displays, it cannot effectively control the coating solution area, resulting in serious evaporation of the coating solution, large concentration fluctuations, and easy mixing of impurities into the coating solution. This leads to uneven coating composition, high surface defect rate, and large emissions of harmful gases, threatening the safety of operators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to effectively control the plating solution area, resulting in severe evaporation of the plating solution, large concentration fluctuations, easy mixing of impurities, uneven coating composition, and high surface defect rate. Therefore, this invention proposes a chemical coating device for mobile phone displays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A chemical coating apparatus for mobile phone displays, comprising: A coating chamber has a plating solution cavity at its top and a placement cavity on one side of the coating chamber below the plating solution cavity. The coating tank is equipped with a stirring mechanism for stirring the coating solution in the coating chamber. The coating tank is also equipped with a sealing component for sealing the coating area.

[0006] In one possible design, the stirring mechanism includes a stirring disc that is rotatably and sealed on the bottom wall of the plating chamber, a motor that is fixedly mounted on the top wall of the placement chamber, the output shaft of the motor being fixedly connected to the stirring disc, and a door panel that is hinged to one side of the coating box at the opening of the placement chamber, with a handle fixedly mounted on one side of the door panel.

[0007] In one possible design, the sealing assembly includes two covers symmetrically hinged to the top of the coating chamber at the opening of the plating solution chamber via hinges. A support frame is fixedly installed on the rear side of the coating chamber. A sliding groove is provided on one side of the support frame. A slide is slidably arranged inside the sliding groove. A connecting rod is fixedly installed on one side of the slide. Both ends of the connecting rod are hinged to linkage rods. The other ends of the two linkage rods are respectively hinged to one side of the two covers.

[0008] In one possible design, a hydraulic cylinder is fixedly mounted on the top of the support frame, a connecting plate is fixedly mounted on the output end of the hydraulic cylinder, a linkage frame is fixedly mounted on one side of the connecting plate, and the bottom end of the linkage frame is fixedly connected to the top of the slide.

[0009] In one possible design, two connecting columns are symmetrically fixedly arranged at the bottom of the connecting plate, and the bottom of the two connecting columns is fixedly arranged with the same frame. The frame has multiple layers, and each layer of the frame holds a display screen holder.

[0010] In one possible design, the two covers are symmetrically provided with semi-circular grooves on their adjacent sides, and a rubber pad is fixedly installed in each semi-circular groove, with the position of the semi-circular groove corresponding to the position of the connecting post.

[0011] In this application, when the coating process begins, the entire equipment is first powered on to ensure it is in normal working condition. Then, the prepared coating solution (containing metal salts such as copper sulfate and nickel chloride, which are the main substances forming the coating, reducing agents such as sodium hypophosphite and glucose, which promote the reduction of metal ions to metal and their deposition on the display screen surface, and stabilizers to effectively prevent decomposition and ensure stable performance) is injected into the coating solution chamber at the top of the coating chamber. After the coating solution is injected, the mobile phone display screen, which has undergone pretreatment processes such as chemical degreasing, roughening, and sensitization / activation, is carefully placed in the display screen holder. The display screen is then placed securely within the holder. Next, the display screen holders containing the display screens are placed one by one into the frame. At this point, the frame is in its initial, elevated position, and both covers are open (e.g., Figure 2 (as shown) After preparations are complete, start the hydraulic cylinder. The output end of the hydraulic cylinder slowly extends, pushing the connecting plate downward. As the connecting plate moves downward, it pushes the frame and the mobile phone display inside it into the plating chamber through the connecting column. At the same time, the linkage frame fixedly connected to one side of the connecting plate also descends, thereby driving the slide to slide downward in the slide groove opened on one side of the support frame. As the slide descends, the linkage rod pulls the two covers to rotate around the hinge, gradually closing them towards the opening of the plating chamber. When the frame is lowered to the appropriate position in the plating chamber, that is, when the mobile phone display screen is completely immersed in the plating solution, the two covers also close completely, sealing the plating chamber. The two covers have symmetrical semi-circular grooves on the side closest to each other, and the rubber gaskets fixed in the grooves are in close contact with the connecting column, thus ensuring a good seal when the covers are closed. This effectively reduces the evaporation and concentration fluctuation of the plating solution, prevents impurities from mixing in, ensures uniform plating composition, reduces surface defect rate, and also reduces the emission of harmful gases, ensuring the safety of operators and environmental compliance. During the coating process, the motor is started to operate. The motor's output shaft drives a sealed stirring plate mounted on the bottom wall of the coating chamber to rotate. The stirring plate agitates the coating solution at a uniform speed, maintaining the uniformity of the solution composition, preventing sedimentation, and ensuring that the required metal layer is uniformly deposited on the surface of the mobile phone display screen. If it is necessary to heat the coating solution to improve the film quality, the heating function of the equipment is activated (the heating function includes heating wires or heating tubes embedded inside the coating chamber and located around the periphery of the coating chamber, such as...). Figure 3 (as shown) After the coating is completed, the hydraulic cylinder is restarted to retract its output end, which drives the connecting plate, linkage frame, slide and other components to rise. During the rise of the slide, the two covers are pushed to rotate around the hinge through the linkage rod and gradually open. At the same time, the frame rises with the connecting plate and lifts the coated mobile phone display screen out of the coating solution. The display screen placement rack can then be taken out and the coated mobile phone display screen is removed from the display screen placement rack for subsequent processing.

[0012] This utility model has the following beneficial effects: In this invention, the stirring mechanism enables the motor to drive the stirring plate to rotate at a constant speed on the bottom wall of the plating chamber during the coating process, continuously stirring the plating solution. This effectively maintains the uniformity of the plating solution composition, avoids sedimentation, and ensures that the surface of the mobile phone display screen can be uniformly coated with the required metal layer, thereby guaranteeing the coating quality and improving the coating effect.

[0013] In this invention, by setting up a closed component, when the frame drives the display screen to be immersed in the plating solution, the two covers completely close and seal the plating solution cavity, effectively reducing the evaporation and concentration fluctuation of the plating solution, preventing impurities from mixing into the plating solution, ensuring uniform plating composition, reducing surface defect rate, and reducing harmful gas emissions, thus ensuring the safety of operators and the environment.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment Reference Figure 1-4 A coating apparatus, comprising: The coating box 1 has a plating solution cavity 101 on its top for holding the plating solution. The cavity is used for chemical coating of mobile phone display screens. A placement cavity 102 is provided on one side of the coating box 1, below the plating solution cavity 101. This placement cavity 102 is used to install components such as motor 3.

[0018] A stirring mechanism is installed inside the coating chamber 1 to stir the coating solution in the coating solution chamber 101. The stirring plate 2 is sealed and rotates on the bottom wall of the coating solution chamber 101. The motor 3 is fixedly installed on the top wall of the placement chamber 102. The output shaft of the motor 3 is fixedly connected to the stirring plate 2. When the motor 3 is started, the output shaft of the motor 3 rotates and drives the stirring plate 2 to rotate, thereby stirring the coating solution in the coating solution chamber 101, maintaining the uniformity of the coating solution composition, avoiding sedimentation, and ensuring that the surface of the mobile phone display screen can be uniformly coated with the required metal layer. A door panel 15 is hinged at the opening of the placement chamber 102. A handle is fixedly installed on one side of the door panel 15. The operator can open or close the door panel 15 by holding the handle, which facilitates the inspection and maintenance of components such as the motor 3 in the placement chamber 102.

[0019] The sealing assembly is used to seal the coating area, reducing the evaporation and concentration fluctuation of the coating solution, preventing impurities from entering, ensuring uniform coating composition and reduced surface defect rate, while also reducing harmful gas emissions, ensuring operator safety and environmental compliance. Two covers 4 are symmetrically hinged at the top of the coating chamber 1 and the opening of the coating solution chamber 101. A support frame 5 is fixedly installed on the rear side of the coating chamber 1. A slide groove 501 is opened on one side of the support frame 5, and a slide 6 is slidably installed inside the slide groove 501. A connecting rod 7 is fixedly installed on one side of the slide 6, and both ends of the connecting rod 7 are hinged to linkage rods 8. The other ends of the two linkage rods 8 are respectively hinged to one side of the two covers 4. A hydraulic cylinder is fixedly installed on the top of the support frame 5. 9. A connecting plate 10 is fixedly installed at the output end of the hydraulic cylinder 9. A linkage frame 11 is fixedly installed on one side of the connecting plate 10. The bottom end of the linkage frame 11 is fixedly connected to the top of the slide 6. When the hydraulic cylinder 9 is started, the output end of the hydraulic cylinder 9 extends or retracts, driving the connecting plate 10 to move up and down. When the connecting plate 10 moves downward, it drives the slide 6 to slide downward in the slide groove 501 through the linkage frame 11. During the descent of the slide 6, the two covers 4 are pulled around the hinge by the connecting rod 7 and the linkage rod 8, gradually closing towards the opening of the plating chamber 101. When the connecting plate 10 moves upward, it drives the slide 6 to rise. During the rise of the slide 6, the two covers 4 are pushed around the hinge by the linkage rod 8, gradually opening.

[0020] The two covers 4 have symmetrical semi-circular grooves on their adjacent sides, and each semi-circular groove is fixedly fitted with a rubber pad 401. The position of the semi-circular grooves corresponds to the position of the connecting post 12. When the covers 4 are closed, the rubber pads 401 are tightly attached to the connecting post 12, which enhances the sealing effect, effectively reduces the evaporation and concentration fluctuation of the plating solution, prevents impurities from mixing into the plating solution, ensures the quality of the plating layer, and reduces the emission of harmful gases, providing a safe working environment for operators and meeting environmental protection requirements.

[0021] This application can be used in the field of chemical coating equipment technology for mobile phone displays, and can also be used in other fields applicable to this application.

[0022] In another embodiment Reference Figure 4 A mobile phone display screen chemical coating equipment is applied to the field of mobile phone display screen chemical coating equipment technology. Two connecting columns 12 are symmetrically fixed at the bottom of the connecting plate 10. The same frame 13 is fixed at the bottom of the two connecting columns 12. The frame 13 has multiple layers, and each layer holds a display screen placement rack 14. During operation, the pre-treated mobile phone display screen is first placed in the display screen placement rack 14, and then the display screen placement rack 14 is placed in each layer of the frame 13. The hydraulic cylinder 9 is activated to lower the frame 13 and immerse the mobile phone display screen in the plating solution 101 for coating. At the same time, the two caps 4 close and seal the plating solution 101.
