Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED panel production, in particular to a switching spraying mechanism. Background Art
[0002] With the continuous development of LED technology, LED panels are increasingly used in lighting, display, and decoration. Surface treatment of LED panels has become a key step in improving their performance and aesthetics, with spraying paint being one of the most commonly used treatment methods. Traditional LED panel spraying operations often rely on manual operation, which is not only inefficient but also difficult to achieve high-precision spraying control, easily leading to problems such as paint waste and uneven spraying. In addition, in response to diverse market demands, LED panels often require spraying paint of different colors or paints with special functions. Traditional spraying methods are unable to cope with paint switching, increasing production costs and time costs.
[0003] To improve the efficiency and quality of LED panel spraying while meeting market demand for a wider range of coatings, the industry is exploring automated and intelligent spraying solutions. In this context, a spraying mechanism that can precisely control spraying position and quickly switch between coatings is particularly important. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a switchable spraying mechanism, which solves the problems raised by the above-mentioned background technology.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a switching spraying mechanism, including a horizontal drive linear motor, the driving end of the horizontal drive linear motor is installed with a vertical drive linear motor, the driving end of the vertical drive linear motor is installed with a paint switching spraying module, the horizontal drive linear motor and the vertical drive linear motor can both adjust the spraying position of the paint switching spraying module, and the paint switching spraying module can switch between the spraying of at least two types of paints.
[0006] Furthermore, the paint switching spray module includes a paint storage tank No. 1, a paint storage tank No. 2 and a solenoid valve, all of which are installed at the driving end of the vertical drive linear motor. The paint inside the paint storage tank No. 1 and the paint storage tank No. 2 is transported to the solenoid valve through a pipeline. A paint spray gun is installed at the bottom of the solenoid valve, and the solenoid valve can only transport one type of paint to the paint spray gun at the same time.
[0007] Furthermore, the No. 1 paint storage tank and the No. 2 paint storage tank are both installed on both sides of the driving end of the vertical drive linear motor through the tank bracket, and the solenoid valve is installed on the front side of the driving end of the vertical drive linear motor.
[0008] Furthermore, the solenoid valve is a four-way solenoid valve having three inlets and one outlet. The three inlets are a paint inlet and an air inlet located on both sides of the solenoid valve, an air inlet located at the top of the solenoid valve, and a paint outlet located at the bottom of the solenoid valve.
[0009] Furthermore, the paint outlet at the bottom of the No. 1 paint storage tank is connected to the No. 1 paint inlet via a No. 1 paint delivery pipe, and the paint outlet at the bottom of the No. 2 paint storage tank is connected to the No. 2 paint inlet via a No. 2 paint delivery pipe.
[0010] Furthermore, the paint spray gun is installed inside the paint outlet, and the solenoid valve is equipped with an air duct connected to the air inlet, a paint channel No. 1 connected to the paint inlet No. 1, a paint channel No. 2 connected to the paint inlet No. 2, and a paint outlet channel connected to the paint outlet. The solenoid valve can control the connection between the paint inlet No. 1, the air inlet, and the paint outlet, or the connection between the paint inlet No. 1, the air inlet, and the paint outlet.
[0011] The utility model provides a switchable spraying mechanism. Compared with the prior art, it has the following beneficial effects:
[0012] This spray mechanism achieves precise two-dimensional movement of the spray module through precise control of the horizontal and vertical linear motors, enabling uniform and rapid painting of the LED panels. This not only improves spraying efficiency but also ensures stable and consistent spray quality. The paint switching spray module design allows for easy switching between different paints (such as those with different types, colors, or functions). By switching the internal channels of the four-way solenoid valve, only one type of paint is delivered to the paint gun, avoiding paint mixing and contamination. This design significantly shortens paint switching time and improves the flexibility and adaptability of the production line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-5 The utility model provides a technical solution: a switching spraying mechanism, which consists of three core parts: a horizontal drive linear motor 1, a vertical drive linear motor 2 (the horizontal drive linear motor 1 and the vertical drive linear motor 2 adopt existing technologies and are not described in detail here), and a paint switching spraying module 3. The horizontal drive linear motor 1 serves as the horizontal movement component of the entire mechanism, and its driving end is fixedly connected to the vertical drive linear motor 2. The position adjustment of the spraying module in the horizontal direction is achieved through precise control. The vertical drive linear motor 2 is installed at the driving end of the horizontal drive linear motor 1, and is responsible for moving the paint switching spraying module 3 in the vertical direction, thereby achieving precise control of the spraying height. The paint switching spraying module 3 is used to realize switching and spraying of different paints.
[0021] The paint switching spraying module 3 includes a paint storage tank No. 1 31, a paint storage tank No. 2 32, a solenoid valve 33 and a paint spray gun 34. The paint storage tank No. 1 31 and the paint storage tank No. 2 32 store two different paints respectively (which can be different models or different colors). Both are installed on both sides of the driving end of the vertical drive linear motor 2 through a tank bracket 37 to ensure stability and easy maintenance. The solenoid valve 33 adopts a four-way solenoid valve design with three inlets (paint inlet No. 1 331, paint inlet No. 2 332, air inlet 333) and one outlet (paint outlet 334). The solenoid valve realizes the function of only delivering one type of paint to the paint spray gun 34 by switching the internal channel. The air inlet 333 is used to introduce compressed air to assist in the spraying of the paint. The paint spray gun 34 is directly installed inside the paint outlet 334 of the solenoid valve 33, and receives and sprays the corresponding paint according to the switching state of the solenoid valve;
[0022] The No. 1 paint storage tank 31 is connected to the No. 1 paint inlet 331 of the solenoid valve 33 via the No. 1 paint delivery pipe 35; the No. 2 paint storage tank 32 is connected to the No. 2 paint inlet 332 of the solenoid valve 33 via the No. 2 paint delivery pipe 36. This design ensures that the paint can be delivered to the solenoid valve smoothly and without pollution. The solenoid valve is internally provided with an air duct, a No. 1 paint channel, a No. 2 paint channel, and a paint outlet channel. By controlling the switch of the internal channel of the solenoid valve, it is possible to switch between No. 1 paint and No. 2 paint. When the solenoid valve is switched to the No. 1 paint channel, the No. 1 paint and compressed air enter the paint outlet channel through the air duct and are finally sprayed out by the paint spray gun 34; similarly, when the solenoid valve is switched to the No. 2 paint channel, the No. 2 paint is sprayed out.
