Description

Technical Field

[0001] This invention relates to the field of UV cleaning technology, and particularly to a UV cleaning system. Background Technology

[0002] UV cleaning technology is a novel and cutting-edge material cleaning technology for electronic products. It utilizes a UV light source that emits high-energy light waves with wavelengths of 185nm and 254nm. When these waves act on the surface of the object being cleaned, oxygen molecules in the air absorb the 185nm wavelength ultraviolet light due to photosensitivity, producing ozone and atomic oxygen. Ozone strongly absorbs the 254nm wavelength ultraviolet light, decomposing into atomic oxygen and oxygen gas. Because atomic oxygen is extremely reactive, it can cause the decomposition and physicochemical synthesis of carbon and hydrocarbons on the object's surface, releasing volatile gases such as carbon dioxide and water vapor, thus thoroughly removing contaminants adhering to the object's surface.

[0003] Chinese invention patent CN114558848A discloses a fully automatic UV cleaning equipment, including a UV cleaning chamber, a material conveying system, an exhaust system connected to the UV cleaning chamber, and an electrical control system. The UV cleaning chamber is used to clean surface contaminants adhering to electronic product materials using UV cleaning lamps. The material conveying system is used to transport the electronic product materials to be cleaned into the UV cleaning chamber and transfer the cleaned electronic product materials from the UV cleaning chamber to the unloading position. The exhaust system is used to extract air from the UV cleaning chamber to regulate the temperature and ozone content within the UV cleaning chamber. The electrical control system is used to control the UV cleaning chamber, the material conveying system, and the exhaust system to cooperate in completing the cleaning of the electronic product materials. This invention solves the problem that existing circuit board UV cleaning methods lack full automation and streamlined production lines.

[0004] However, during the use of UV cleaning lamps, scale will form on the surface of the lamp tubes. This will inevitably affect the lamp tubes' ability to irradiate and clean. The existing methods of managing them, such as manual cleaning or periodic replacement, are too cumbersome and cannot clean the lamp tubes in a timely manner, thus affecting the efficiency of cleaning materials.

[0005] Therefore, it is necessary to provide a UV cleaning system to solve the above-mentioned technical problems. Summary of the Invention

[0016] As a further aspect of the present invention: the jetting mechanism further includes multiple nozzles, the mounting frame has a cavity inside, the air outlet pipe is fixedly connected to the mounting frame, and the multiple nozzles are all fixedly connected to the top of the mounting frame and connected to the cavity of the mounting frame.

Detailed Implementation

[0033] like Figures 1 to 7 As shown, a UV cleaning system includes the following embodiments:

[0034] Example 1: Includes an operating table 1, with a support frame 2 fixedly connected to the top of the operating table 1, and further includes:

[0035] Placement plate 3 is set on the top of the operating table 1. A drive assembly is set on the outside of the placement plate 3 for conveying materials. The drive assembly includes two first lead screws 301, which both pass through the placement plate 3 and are rotatably connected to the placement plate 3. The first lead screws 301 are rotatably connected to the support frame 2. A drive motor is fixedly connected to the outside of the support frame 2. The output end of the drive motor is fixedly connected to the first lead screws 301.

[0036] Cleaning cover 4 is located inside the support frame 2. A first hydraulic telescopic rod 5 is fixedly connected between the top of the cleaning cover 4 and the top of the inside of the support frame 2. Multiple UV tubes 6 are installed inside the top of the cleaning cover 4.

[0037] Rotate the square rod 8. The square rod 8 is set inside the support frame 2. Both ends of the square rod 8 are connected to the moving plate 7. The square rod 8 and the moving plate 7 are rotatably connected. The top of the square rod 8 is connected to the mounting frame 9 through the elastic element. The top of the mounting frame 9 is fixedly connected to the elastic arc-shaped clamp 901 corresponding to the multiple UV tubes 6. The support frame 2 is equipped with a starting element for the reciprocating movement of the moving plate 7.

[0038] A flipping component, located on one side of the movable plate 7, is used to drive the rotating square rod 8 to flip, so that the elastic arc-shaped clamp 901 fits into the UV tube 6.

[0039] In practice, after the material is placed on top of the placement plate 3, the drive assembly is activated. When the material reaches below the cleaning hood 4, the first hydraulic telescopic rod 5 is activated, causing the cleaning hood 4 to descend and cover the material on top of the placement plate 3. Then, the material is cleaned with ultraviolet light through the UV tube 6 at the top of the cleaning hood 4. Oxygen molecules in the air absorb 185nm wavelength ultraviolet light and produce ozone and atomic oxygen. Ozone also has a strong absorption effect on 254nm wavelength ultraviolet light, and it decomposes into atomic oxygen and oxygen. Atomic oxygen is extremely reactive; under its action, the decomposition products of carbon and hydrocarbons on the surface of the object can be synthesized into volatile gases such as carbon dioxide and water vapor, which escape from the surface, thus thoroughly removing carbon and organic pollutants adhering to the object's surface.

[0040] When a large amount of substances decompose, they will adhere to the outside of the UV tube 6, forming scale, which will affect the irradiation effect of the UV tube 6. Therefore, in this solution, the drive component is activated to drive the rotating square rod 8 to move back and forth, and the elastic arc-shaped clamp 901 fixedly connected to the top of the mounting frame 9 is attached to the outside of the UV tube 6 to treat the surface of the UV tube 6, thereby ensuring the irradiation effect of the UV tube 6.

[0041] Meanwhile, in order to ensure that the elastic arc-shaped clamp 901 does not affect the irradiation of the UV tube 6, the rotating square rod 8 is rotated by the flipping component, thereby separating the elastic arc-shaped clamp 901 from the UV tube 6.

[0042] like Figure 5 - Figure 6 As shown, further: the flipping component includes a rotating shaft 803 rotatably connected to one side of the moving plate 7. The rotating shaft 803 and one end of the rotating square rod 8 are both fixedly connected to pulleys 801. The two pulleys 801 are connected by belt drive. A first gear 802 is fixedly connected to the outside of the rotating shaft 803. A first rack 804 is meshed with the outside of the first gear 802. The first rack 804 is fixedly connected to the top of the cleaning cover 4.

[0043] The flipping component also includes a limiting groove 905 opened on the side of the movable plate 7 near the rotating square rod 8, and a connecting shaft is fixedly connected to one end of the mounting frame 9. The connecting shaft extends into the limiting groove 905 and is slidably connected to the limiting groove 905.

[0044] The starting component includes a second lead screw 701, which passes through the movable plate 7 and is connected to the movable plate 7 via a ball nut pair. A support plate 702 is rotatably connected to the outside of the second lead screw 701. The support plate 702 is fixedly connected to the cleaning cover 4. A servo motor 703 is fixedly connected to the outside of the support plate 702. The output end of the servo motor 703 is fixedly connected to the second lead screw 701.

[0045] The elastic element includes a first spring 904 and a telescopic rod 903. The two ends of the first spring 904 and the telescopic rod 903 are respectively fixedly connected to the mounting frame 9 and the rotating square rod 8.

[0046] In specific implementation, the initial state of the rotating square rod 8 and the mounting frame 9 is horizontal with respect to the ground. When the second lead screw 701 drives the moving plate 7 to move, the first gear 802 on one side of the moving plate 7 moves to the position of the first rack 804 and meshes with the first rack 804. Then the first gear 802 rotates, which in turn drives the first gear 802 to rotate. Then, through the transmission of the pulley 801, the rotating square rod 8 rotates counterclockwise, so that the elastic arc-shaped clamp 901 on the mounting frame 9 fits against the UV tube 6. In order to ensure the stability of the mounting frame 9 after rotation, a limiting groove 905 is opened on one side of the moving plate 7. When the mounting frame 9 rotates with the rotating square rod 8 through the elastic element, the connecting shaft at one end of the mounting frame 9 also slides in the limiting groove 905. The mounting frame 9 can remain stable through the pushing of the elastic element.

[0047] like Figure 3 - Figure 6 As shown, Embodiment 2 also includes a jetting mechanism. The jetting mechanism includes a rotating rod 101 rotatably connected to the outside of the moving plate 7. A pressing plate 103 and a second gear 108 are fixedly connected to the outside of the rotating rod 101. A second rack 109 is fixedly connected inside the support frame 2. The second rack 109 meshes with the second gear 108. An air cylinder 10 is fixedly connected to the outside of the moving plate 7. A push plate 105 is slidably connected inside the air cylinder 10. A second spring 104 is fixedly connected between the push plate 105 and one end inside the air cylinder 10. An air inlet pipe 106 and an air outlet pipe 107 are fixedly connected to the end of the air cylinder 10 away from the push plate 105. A one-way valve is provided on the outside of both the air inlet pipe 106 and the air outlet pipe 107.

[0048] The jetting mechanism also includes multiple nozzles 902. A cavity is provided inside the mounting frame 9. The air outlet pipe 107 is fixedly connected to the mounting frame 9. The multiple nozzles 902 are all fixedly connected to the top of the mounting frame 9 and connected to the cavity of the mounting frame 9.

[0049] In specific implementation, when the moving plate 7 moves, the second gear 108 on one side of the moving plate 7 meshes with the second rack 109, thereby driving the fixedly connected rotating rod 101 to rotate. The rotating rod 101 drives the fixedly connected extrusion plate 103, which in turn extrudes the push plate 105. This causes the push plate 105 to compress the air inside the air cylinder 10 and discharge it through the air outlet pipe 107 into the cavity inside the mounting frame 9. The air is then discharged through the nozzle 902. When the elastic arc clamp 901 cleans the UV tube 6, the gas sprayed from the nozzle 902 can cooperate with the elastic arc clamp 901 to clean, thus improving the cleaning effect.

[0050] Example 3: A cleaning frame 11 is fixedly connected to one side of the support plate 702. The cleaning frame 11 has a cleaning groove 111 on the outside that corresponds to a plurality of elastic arc-shaped clamps 901. A brush is provided inside the cleaning groove 111. A third rack 112 is fixedly connected to the top of the inside of the support frame 2. The third rack 112 meshes with the lower part of the first gear 802.

[0051] In specific implementation, when the moving plate 7 moves to the third rack 112, the third rack 112 meshes with the first gear 802, thereby rotating the square rod 8, which in turn rotates the square rod 8 and the mounting frame 9 to the initial state, and the elastic arc-shaped clamp 901 is inserted into the cleaning groove 111 opened on one side of the cleaning frame 11, so that the elastic arc-shaped clamp 901 is cleaned by the brush.

[0052] Furthermore, a suction device 13 is fixedly connected to the top of the support frame 2. The suction end of the suction device 13 is fixedly connected to two connecting pipes 131, which extend into the cleaning hood 4 respectively.

[0053] In practice, the ozone content inside the support frame 2 is controlled by the extraction device 13 and adjusted as needed to ensure the irradiation effect of the UV tube 6.
