Description

Technical Field

[0001] This utility model relates to the field of electroplating and printing technology, specifically to a panel surface texture electroplating and printing device. Background Technology

[0002] Currently, when it is necessary to add a metallic texture to the surface of a panel, screen printing is often used. By mixing different proportions of metallic inks, screen printing is used to achieve the textured appearance effect of the plastic film.

[0003] As mentioned in announcement number CN114517314A, titled "An Electroplating Paste for Screen Printing and Its Preparation Method and Application," an electroplating paste for achieving this effect is described. This electroplating paste for screen printing is composed of the following components by mass percentage: 5-30% of a first metal salt, 5-35% of a second metal salt, and 0.1-10% of a thickener, with the balance being a solvent. The first metal salt is any one or a combination of at least two of copper, nickel, tin, aluminum, or silver salts, and the second metal salt is a potassium salt and / or a sodium salt.

[0004] However, directly screen printing the texture of plastic panels with metallic ink will result in unclear textures on the film, uncontrollable colors in the light-transmitting areas of the viewing window, and a blurry display effect. Furthermore, metallic ink is conductive, which can cause touch signal interference and lead to touch malfunction when used in touch-enabled panels. Therefore, we propose a panel surface texture electroplating printing device to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a panel surface texture electroplating printing device, comprising a roller conveyor, a lifting transmission mechanism installed above the roller conveyor, and two lifting transmission mechanisms are provided, one of which has a vacuum electroplating mechanism installed at its output end, the vacuum electroplating mechanism comprising a vacuum hood, the vacuum hood having a vacuum chamber inside, a target material solenoid valve connector and a vacuum solenoid valve connector installed at the front end of the vacuum hood, and a screen printing mechanism installed at the output end of the other lifting transmission mechanism, and a panel support tray provided on the roller conveyor.

[0008] Preferably, the lifting transmission mechanism includes a bracket, a top plate, and a hydraulic cylinder. The bracket is installed at the four corners of the lower end of the top plate, the hydraulic cylinder is installed at the upper end of the top plate, and the output end of the hydraulic cylinder passes through and extends to the lower end of the top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention employs a combined approach of vacuum electroplating and screen printing. During printing, the panel is first transported to the vacuum electroplating unit by a roller conveyor, where an electroplating layer is deposited on the panel surface to achieve a metallic texture. Then, the texture is printed using non-conductive ink through a screen printing unit. This achieves the metallic texture without affecting the touch functionality of the panel. It solves the problem that directly using metallic ink for screen printing on existing plastic panels results in unclear textures on the film, uncontrollable colors in the light-transmitting areas of the viewing window, and blurry display effects. Furthermore, the conductivity of metallic ink can cause touch signal interference and touch malfunction when used in touch-enabled panels. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a panel surface texture electroplating printing device, including a roller conveyor 1, a lifting transmission mechanism 2 installed above the roller conveyor 1, and two lifting transmission mechanisms 2 are provided. One of the lifting transmission mechanisms 2 has a vacuum electroplating mechanism 3 installed at its output end. The vacuum electroplating mechanism 3 includes a vacuum hood 301, a vacuum chamber 303 is provided inside the vacuum hood 301, and a target material solenoid valve connector 304 and a vacuum solenoid valve connector 305 are installed at the front end of the vacuum hood 301. The other lifting transmission mechanism 2 has a screen printing mechanism 4 installed at its output end. A panel support tray 5 is provided on the roller conveyor 1. The lifting transmission mechanism 2 includes a bracket 201, a top plate 202 and a hydraulic cylinder 203. The bracket 201 is installed at the four corners of the lower end of the top plate 202, and the hydraulic cylinder 203 is installed at the upper end of the top plate 202. The output end of the hydraulic cylinder 203 passes through and extends to the lower end of the top plate 202.

[0022] Before use, connect the first and last ends of the roller conveyor 1 to the feeding and unloading conveyors. During printing, the feeding conveyor transports the panels loaded in the panel support tray 5 to the roller conveyor 1. The roller conveyor 1 first transports the panel support tray 5 to below the vacuum electroplating mechanism 3. The lifting transmission mechanism 2 at the vacuum electroplating mechanism 3 operates, and the hydraulic cylinder 203 controls the vacuum hood 301 to move down and press against the panel support tray 5, so that the panel support tray 5 and the vacuum hood 301 form a small closed space. Then, the vacuum solenoid valve connector 305 is opened, and the vacuum equipment connected to it creates a vacuum environment inside the cavity with a vacuum degree of 10 to the power of negative three. After reaching -5 Pascals, the vacuum solenoid valve connector 305 is closed, and the target solenoid valve connector 304 is connected to an external pumping mechanism to introduce the evaporated electroplating target into the cavity, so that the vapor molecules are deposited on the panel surface and cooled. After a certain period of time (the waiting time varies depending on the coating thickness; if the coating thickness is controlled between 150-300nm, it takes 4-15 minutes), the hydraulic cylinder (203) is reset and the vacuum cover 301 is opened. The roller conveyor 1 then continues to send the coated panel to the screen printing mechanism 4. The screen printing mechanism 4 uses non-conductive ink for texture printing, so as to satisfy the metallic texture without affecting the use of the panel's touch function.

[0023] Please see Figure 1 and Figure 3 A positioning sealing groove 501 is provided at the upper edge of the panel support tray 5, and a sealing flange 302 is provided at the lower edge of the vacuum cover 301. The positioning sealing groove 501 and the sealing flange 302 ensure the sealing performance when the panel support tray 5 and the vacuum cover 301 are pressed together.

[0024] Please see Figure 2 and Figure 4The screen printing mechanism 4 includes a connecting frame 401, a printing screen 402, and a feeder 403. The feeder 403 is installed at the rear end of the connecting frame 401, and the printing screen 402 is installed at the lower end of the connecting frame 401. An electric guide rail 405 is installed on one side of the upper end of the printing screen 402, and a scraper 406 is installed on the slider of the electric guide rail 405. Multiple discharge heads 404 are provided on the lower surface of the feeder 403, and a feed pipe connector is installed at the upper end of the feeder 403. A guide post 407 is installed on the other side of the upper end of the printing screen 402, and one end of the scraper 406 is slidably connected to the guide post 407. Next, during screen printing, the roller conveyor 1 transports the panel to the area below the screen printing mechanism 4. Under the action of the lifting transmission mechanism 2, the screen printing mechanism 4 moves down so that the bottom printing screen 402 contacts the panel surface. The feed seat 403 at the end is connected to a pump and a color paste storage tank through a feed pipe joint. The pump pumps the non-conductive ink in the color paste storage tank to the feed seat 403, and sprays an appropriate amount of ink along the discharge head 404 onto the surface of the printing screen 402. Then, the electric guide rail 405 drives the scraper 406 to move back and forth along the surface of the printing screen 402 to evenly scrape the ink and achieve texture printing.

[0025] Furthermore, the roller conveyor 1 includes a frame 101, inside which a plurality of conveying rollers 102 are installed. The ends of adjacent conveying rollers 102 are connected by a sprocket and chain drive. A belt drive mechanism 105 is installed on the outer wall of one end of the frame 101. A servo motor 106 is installed at the end of the belt drive mechanism 105, and the output end of the servo motor 106 is connected to one of the conveying rollers 102 through the belt drive mechanism 105. A plurality of support frames 103 are installed below the roller conveyor 1. A reinforcing rod 104 is installed between adjacent support frames 103. A shock-absorbing foot 107 is installed below the support frame 103.
