Technical Field
[0001] This utility model relates to the field of UV paint spraying and drying technology, specifically a drying device for UV paint spraying on electronic products. Background Technology
[0002] UV paint, also known as ultraviolet light-cured paint or photoinitiated coating, is applied automatically to furniture panels using roller or spray coating equipment. Under ultraviolet light, the initiator decomposes, generating free radicals that trigger a resin reaction, resulting in instant curing into a film. It is currently the most environmentally friendly type of paint. Another interpretation of UV paint is that it is abbreviated as UV paint, unlike PU, PE, and NC paints which are named after their film-forming substances. UV paint is named after its curing method; it is a coating that can rapidly cure into a film within seconds under ultraviolet light. UV paint differs from the PU, PE, and NC paints commonly used by furniture manufacturers. It is a truly green and environmentally friendly paint, containing no volatile substances. Products made with UV paint are green, healthy, and environmentally friendly. After UV paint is applied, it requires drying.
[0003] In actual use, existing drying equipment for UV coating of electronic products requires batch drying of multiple electronic products, resulting in short contact time between the electronic products and the drying chamber, leading to poor drying efficiency and affecting the production efficiency of UV coating drying of electronic products.

[0020] Example: This utility model provides a drying device for UV coating of electronic products. The purpose of this drying device is to solve the technical problem that the processing time of electronic products in the drying chamber is too short under the prior art, which affects the drying efficiency.
[0021] Please see Figures 1-6 This embodiment provides a drying device for UV paint spraying of electronic products, including a drying chamber 1. A fan 101 is installed at the bottom of the drying chamber 1. The fan 101 drives the airflow inside the drying chamber 1 to accelerate the drying efficiency of the UV paint. An insertion groove 102 is provided at the bottom of the drying chamber 1 outside the fan 101. A snap-fit assembly 103 is provided on the inner wall of the insertion groove 102. The snap-fit assembly 103 is composed of a movable groove 1031, a return spring 1032 and a round-headed snap block 1033.

A round-headed snap block 1033 is fixedly connected to one end of the return spring 1032 corresponding to the insertion groove 102.
[0022] In this embodiment, please refer to Figure 2 and Figure 5The bottom of the drying chamber 1 is fixedly attached to the outside of the fan 101 with a dust cover 104. The dust cover 104 has a corresponding hole 1041. The dust cover 104 is inserted into the insertion groove 102. The return spring 1032 pushes the round head block 1033 into the hole 1041 through its own elasticity, so that the dust cover 104 is fixedly attached to the outside of the fan 101, preventing dust from entering the drying chamber 1 through the fan 101. Handles 1042 are fixedly connected to both sides of the dust cover 104. The handles 1042 facilitate the installation and removal of the dust cover 104.
[0023] In this embodiment, please refer to Figure 1 and Figure 2 An inlet 105 is provided on the outside of the drying chamber 1, corresponding to the feeding end of the U-shaped conveyor belt 2. The U-shaped conveyor belt 2 transports the electronic products to be dried into the drying chamber 1 through the feeding end of the inlet 105 for ultraviolet curing. An outlet 106 is provided on the outside of the drying chamber 1, above the inlet 105, corresponding to the discharge end of the U-shaped conveyor belt 3. The U-shaped conveyor belt 3 discharges the electronic products whose surface UV paint has been dried and cured through the output end of the outlet 106.
[0024] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The drying chamber 1 is equipped with a U-shaped conveyor belt 2. The end of the U-shaped conveyor belt 2 away from the feed port 105 is the output end. The drying chamber 1 is equipped with a U-shaped conveyor belt 3 above the U-shaped conveyor belt 2. The end of the U-shaped conveyor belt 3 away from the discharge port 106 is the feeding end.
[0025] In this embodiment, please refer to Figure 2 and Figure 4Inside the drying chamber 1, between U-shaped conveyor belt 2 and U-shaped conveyor belt 3, a feeding assembly 4 is installed. The feeding assembly 4 consists of an intermittent conveyor belt 401, support plates 402, an electric telescopic rod 403, a connecting frame 404, a straight pusher plate 405, and a motor 406. The intermittent conveyor belt 401 is perpendicular to the output end of U-shaped conveyor belt 2. Multiple sets of support plates 402 are fixedly connected to the outside of the intermittent conveyor belt 401. The positions of the support plates 402 correspond to the output end of U-shaped conveyor belt 2 and the feeding end of U-shaped conveyor belt 3. An electric telescopic rod 403 is installed on the inner wall of the drying chamber 1 above the discharge port 106. The electric telescopic rod 403 drives the connecting frame 404 to move back and forth as a whole, facilitating the movement of the support plates 402 when the intermittent conveyor belt 401 drives the support plates 402. 2. To avoid collisions, the end of the electric telescopic rod 403 away from the discharge port 106 is fixedly connected to a connecting frame 404 between the U-shaped conveyor belt 2 3 and the intermittent conveyor belt 401. A straight pusher plate 405 is rotatably connected to the bottom of the connecting frame 404. A motor 406 is installed on one end of the straight pusher plate 405 on the outside of the connecting frame 404. When the electronic product is conveyed to the output end of the U-shaped conveyor belt 2, the intermittent conveyor belt 401 conveys the pushed electronic product to the loading end of the U-shaped conveyor belt 2 3 through the support plate 402. The motor 406 drives the straight pusher plate 405 to rotate, pushing the electronic product on the support plate 402 to the loading end of the U-shaped conveyor belt 2 3. The electronic product continues to be conveyed through the U-shaped conveyor belt 2 3, extending the residence time of the electronic product in the drying chamber 1 and improving the drying efficiency.
[0026] In this embodiment, please refer to Figure 2 The drying chamber 1 is equipped with a UV lamp holder 5, which consists of a connecting rod 501, an annular mounting bracket 502, and an annular UV lamp strip 503. The connecting rod 501 is fixedly connected to the top of the inner wall of the drying chamber 1. An annular mounting bracket 502 is installed on the outside of the connecting rod 501 above the U-shaped conveyor belt 2 and the U-shaped conveyor belt 3. Two annular UV lamp strips 503 are installed below the annular mounting bracket 502. The controller 6 controls the annular UV lamp strips 503 through wires to provide uniform irradiation to the electronic products conveyed on the U-shaped conveyor belt 2 and the U-shaped conveyor belt 3, so that the UV paint on the surface of the electronic products is cured.
[0027] In this embodiment, please refer to Figure 1 A controller 6 is installed on the outside of the drying chamber 1. The controller 6 is electrically connected to the fan 101, U-shaped conveyor belt 1 2, U-shaped conveyor belt 2 3, feeding assembly 4 and annular ultraviolet lamp strip 503 via wires for control.
[0028] In addition, it should be noted that the fan 101, U-shaped conveyor belt 1 2, U-shaped conveyor belt 2 3, feeding assembly 4, ultraviolet lamp holder 5 and controller 6 are all existing technologies, and their internal working principles and operation procedures will not be described in detail here.
[0029] The working process of this utility model is as follows: First, the dustproof mesh cover 104 is inserted into the insertion groove 102. The return spring 1032 pushes the round head locking block 1033 into the locking hole 1041 through its own elasticity, so that the dustproof mesh cover 104 is locked and fixed to the outside of the fan 101, preventing dust from entering the drying chamber 1 through the fan 101. After the drying chamber 1 is powered on, the U-shaped conveyor belt 1 2 transports the electronic products to be dried into the drying chamber 1 for ultraviolet curing through the feeding end at the feeding port 105. When the electronic products are transported to the output end of the U-shaped conveyor belt 1 2, the intermittent conveyor belt 401 transports the pushed electronic products to the feeding end position of the U-shaped conveyor belt 2 3 through the support plate 402. The motor 406 drives the straight pusher plate 405 to rotate, pushing the support plate 402... Electronic products are pushed onto the loading end of U-shaped conveyor belt 2 3 and continue to be conveyed by U-shaped conveyor belt 2 3, extending the residence time of electronic products in drying chamber 1 and improving drying efficiency. Electric telescopic rod 403 drives the connecting frame 404 to move back and forth as a whole, so as to avoid the support plate 402 when the intermittent conveyor belt 401 drives the support plate 402 to operate. Controller 6 controls the ring ultraviolet lamp strip 503 through wires to provide uniform irradiation to the electronic products conveyed on U-shaped conveyor belt 1 2 and U-shaped conveyor belt 2 3, so that the UV paint on the surface of the electronic products is cured. Fan 101 drives the air flow in drying chamber 1, accelerating the drying efficiency of UV paint. U-shaped conveyor belt 2 3 discharges the electronic products whose surface UV paint has been dried and cured through the output end of the discharge port 106.
[0030] The entire operation process is simple and convenient. Compared with existing spray drying equipment, this utility model can extend the processing time of multiple electronic products in the drying chamber, improve drying efficiency, and enhance overall practicality through its design.
[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
