Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, specifically relating to a screen coating spraying device. Background Technology

[0002] In the electronics manufacturing industry, the screen, as a crucial display component, directly impacts the display effect, lifespan, and user experience of the device due to the quality of its surface coating. With the continuous popularization and upgrading of electronic products, the requirements for the efficiency and quality of screen coating spraying are becoming increasingly stringent.

[0003] Traditional screen coating spraying methods mostly rely on manual operation or simple semi-automatic equipment. In manual spraying, operators need to hold a spray gun and spray each screen individually. This method is not only labor-intensive and inefficient, but also prone to uneven coating due to the poor stability of manual operation, resulting in inconsistent coating thickness, missed areas, and inconsistent screen quality with a high scrap rate. While some simple semi-automatic spraying equipment improves production efficiency to some extent, it still has many limitations. For example, some equipment can only spray a single screen; when spraying one screen, the equipment needs to be stopped for screen replacement, leading to low equipment utilization and failing to meet the needs of large-scale production. Therefore, this application proposes a screen coating spraying device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This embodiment provides a device for spraying coating on a device screen, the structural diagram of which is shown below. Figures 1-5 As shown, it includes an operating table 1, a turntable 2, a mold base 3, and a spraying assembly 4.

[0018] In this embodiment, a turntable 2 is rotatably mounted on the top of the operating table 1. Specifically, a bearing seat is provided at the center of the operating table 1, and the central axis of the turntable 2 is mounted in the bearing seat through a bearing, allowing the turntable 2 to rotate freely around its central axis. Multiple mold bases 3 are provided on the turntable 2; in this embodiment, four mold bases 3 are provided, evenly distributed around the rotation axis of the turntable 2, i.e., the included angle between any two adjacent mold bases 3 is 90°. Each mold base 3 consists of a mold frame 5 and a mold body 6. The mold frame 5 is fixed on the turntable 2, and the mold body 6 is movably fitted into the mold frame 5. The mold body 6 has a mold groove capable of accommodating the screen to be coated. The shape and size of the mold groove are designed according to the specifications of the screen to be coated, ensuring that the screen can be accurately embedded and stably fixed. The mold body 6 can be replaced according to the specifications of the screen to be coated.

[0019] Furthermore, each mold base 3 on the turntable 2 is surrounded by a barrier 7. The barrier 7 shields the side of the mold base 3 facing the center of the turntable 2 and the two sides of the mold base 3 to prevent the coating from splashing onto other parts during the spraying process. A motor 13 is fixedly embedded in the operating table 1. The output shaft of the motor 13 is coaxially connected to the rotation shaft of the turntable 2. The rotation of the motor 13 drives the turntable 2 to rotate, thereby realizing the positioning and switching of the screens to be sprayed on different mold bases 3.

[0020] Furthermore, in this embodiment, a spraying assembly 4 and a push-pull component are provided on one side of the top of the operating table 1. The spraying assembly 4 includes a telescopic arm 8, a horizontal arm 9, and a nozzle 10. The telescopic arm 8 is vertically arranged on one side of the turntable 2 and has a telescopic function. The horizontal arm 9 is horizontally fixed to the top of the movable arm 18. The nozzle 10 is installed at the bottom of the horizontal arm 9 facing the turntable 2, and the nozzle 10 is aligned with the rotation trajectory of the mold base 3 to ensure that the nozzle 10 can accurately aim at the screen to be sprayed on the mold base 3 for spraying operations during the rotation of the turntable 2. The control panel 1 is equipped with a slide 11, and the telescopic arm 8 is installed on the slide 11. Specifically, the telescopic arm 8 includes a fixed sleeve arm 17 vertically fixed on the slide 11 and a movable arm 18 movably passing through the top of the fixed sleeve arm 17. A second electric push rod 19 is vertically installed inside the fixed sleeve arm 17. The telescopic end of the second electric push rod 19 is connected to the inner top wall of the movable arm 18. The telescopic movement of the movable arm 18 within the fixed sleeve arm 17 is driven by the telescopic movement of the second electric push rod 19, thereby realizing the telescopic function of the telescopic arm 8.

[0021] Furthermore, in this embodiment, the push-pull component includes a first electric push rod 12 horizontally fixed on the operating table 1. The telescopic end of the first electric push rod 12 is connected to the slide 11. The telescopic movement of the first electric push rod 12 drives the slide 11 to move horizontally on the operating table 1, thereby driving the entire spraying assembly 4 to move horizontally. To ensure the stability of the movement of the slide 11, a guide rail 14 is fixed on the operating table 1. The guide rail 14 is distributed along the telescopic direction of the first electric push rod 12. The slide 11 is slidably sleeved with the guide rail 14, so that the slide 11 moves smoothly under the guidance of the guide rail 14.

[0022] In this embodiment, a support plate 16 is fixed at one end of the bottom of the operating table 1 near the turntable 2. The support plate 16 serves to support and stabilize the operating table 1. A support rod 15 is vertically fixed at the other end of the bottom of the operating table 1. The support rod 15 is also used to support the operating table 1 and ensure the stability of the entire device during operation.

[0023] Working principle: When using the screen coating spraying device of this equipment, firstly, the screen to be coated is embedded into the mold groove of the mold body 6, and then the mold body 6 is embedded into the mold frame 5 to complete the positioning and fixing of the screen to be coated. Start the motor 13, which drives the turntable 2 to rotate. When one of the mold bases 3 rotates to be directly below the nozzle 10, the motor 13 stops rotating. At this time, start the second electric push rod 19. The telescopic end of the second electric push rod 19 extends, pushing the movable arm 18 upward, driving the horizontal arm 9 and the nozzle 10 to rise to a suitable height. Then start the first electric push rod 12. The telescopic end of the first electric push rod 12 extends, pushing the slide 11 to move horizontally on the guide rail 14, driving the spraying assembly 4 to move horizontally above the screen to be coated. Next, start the nozzle 10, and the nozzle 10 begins the spraying operation on the screen to be coated. During the spraying process, the telescopic amount of the first electric push rod 12 and the second electric push rod 19 can be adjusted as needed to control the position and height of the nozzle 10, ensuring that the coating is evenly sprayed on the screen. After one screen is painted, the nozzle 10 is closed, and the first electric push rod 12 and the second electric push rod 19 are reset, driving the painting assembly 4 back to its initial position. The motor 13 is restarted, and the turntable 2 continues to rotate, rotating the next mold base 3 to directly below the nozzle 10. The above painting process is repeated until all screens on all mold bases 3 have been painted.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
