Description

Technical Field

[0001] This invention belongs to the field of diffusion plate production technology, specifically a surface spraying device for diffusion plate production. Background Technology

[0002] A diffuser is an optical material with great practical value. It can achieve the wonderful purpose of uniform light distribution or create special optical effects by cleverly adjusting the propagation path of light. It has a wide range of applications in lighting, display, acoustics and many other fields. The light diffuser mainly works by utilizing the refraction, reflection and scattering phenomena that occur at the interface of media. Specifically, the material is treated by chemical or physical means to change the path of light. The core principle is that when light enters a medium with a different refractive index from one medium, refraction and reflection will inevitably occur. Moreover, if there are carefully designed microstructures or uniformly distributed diffuser particles in the medium, the light will be further scattered. Through this series of refraction, reflection and scattering processes, the light rays that were originally in different directions are reintegrated and finally form a uniform surface light source, providing ideal lighting conditions for various application scenarios.

[0003] In the production process of diffuser plates, in order to improve their optical performance and surface texture, it is often necessary to spray the surface of the plate to form a coating. In the double-sided spraying process, traditional spraying equipment can only complete the coating coverage on one side of the diffuser plate in one operation. After the first side is sprayed, the plate needs to be transferred to the curing area to wait for the coating to cure. This step-by-step operation mode not only prolongs the overall production cycle, but also increases the risk of surface damage due to multiple handling, which has a dual impact on production efficiency and product yield. Therefore, a surface spraying device for diffuser plate production is proposed. Summary of the Invention

Each of the two support rods is fixedly connected to a support plate at the end that is close to each other, and a pair of second telescopic rods are fixedly connected to the side of the support plates that is far from each other.

[0011] Preferably, each of the output ends of the second telescopic rod is fixedly connected to a clamping block, the clamping block is slidably connected to the support plate, and the opening on the side of the clamping blocks that are close to each other is in an outwardly expanding shape.

[0012] Preferably, the cleaning and spraying assembly includes a guide rail fixedly connected to the spraying box body and two pairs of support rods fixedly connected to the spraying box body.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides a surface coating apparatus for the production of diffusion plates, including a worktable 1 and a diffusion plate body 8, and further comprising: Spraying box assembly 4, which is installed on one side of the workbench 1, is used to provide a closed space for spraying the diffuser plate body 8. The clamping and flipping assembly 5 is installed inside the spray box assembly 4 and is used to clamp and flip the diffuser plate body 8. Cleaning and spraying assembly 6, which is located inside spraying box assembly 4, is used to clean and spray the diffuser plate body 8; Among them, the spray box assembly 4 includes a spray box body 41 fixedly connected to the workbench 1, a spray bracket 42 fixedly connected to the bottom of the spray box body 41, and a pair of first telescopic rods 43 installed at the bottom of the spray bracket 42. The clamping and flipping assembly 5 includes a pair of fixed bases 51 that are fixedly connected to the spray box body 41, and a transmission rod 52 is installed between the pair of fixed bases 51.

[0020] The above solution is adopted: the diffuser plate body 8 is clamped and positioned by the clamping and flipping component 5, and the diffuser plate body 8 can be flipped at the same time to ensure that the diffuser plate body 8 is sprayed on both sides. The spray box assembly 4 provides a sealed space for spraying the diffuser plate body 8, and can also clean up the sprayed paint to prevent paint from escaping and causing pollution. The cleaning and spraying component 6 can simultaneously clean and spray the diffuser plate body 8, and can cooperate with the suction port 44 to ensure that the cleaned dust can be removed in a timely manner.

[0021] like Figure 1 and Figure 2 As shown, a conveyor belt 2 is provided on one side of the top of the workbench 1. A transfer platform 3 is fixedly connected to the workbench 1 at one end of the conveyor belt 2. The side of the transfer platform 3 corresponds to the feed port of the spray box body 41. A pair of conveyor wheels and an adsorption port are provided in the middle of the transfer platform 3.

[0022] The above solution is adopted: by setting up a transfer platform 3, the position of the diffuser plate body 8 is adjusted by the conveying wheels on the top of the transfer platform 3, so that the diffuser plate body 8 can be easily clamped by the clamping block 57. At the same time, the suction port set in the middle of the transfer platform 3 can prevent the diffuser plate body 8 from falling or moving when conveying the diffuser plate body 8 into the spray box body 41 and when taking out the diffuser plate body 8.

[0023] like Figures 2 to 4 As shown, the spray box body 41 has an inverted convex cross-section, and the spray bracket 42 is located at the bottom center of the spray box body 41. The spray bracket 42 abuts against the diffuser plate body 8, and the diffuser plate body 8 does not contact the inside of the spray box body 41 on the upper side of the spray bracket 42. The first telescopic rod 43 is equipped with a negative pressure suction head at its output end. The bottom sides of the spray box body 41 are provided with suction ports 44 at equal intervals. Suction equipment is connected to the suction ports 44. A pair of limiting baffles 45 are provided inside the spray box body 41. The limiting baffles 45 are located on both sides of the spray bracket 42.

[0024] The above solution is adopted as follows: by setting up the spray box assembly 4, the spray box body 41 forms a closed space for spraying the diffuser plate body 8, which avoids the paint from escaping and causing pollution or affecting personnel health. At the same time, the spray box body 41 is set in an inverted U-shape, and the spraying operation is set at the bottom. Through the synchronous suction of the suction port 44 and the space restriction, the paint escaping is further restricted. The setting of the spraying bracket 42 and the first telescopic rod 43 makes the diffuser plate body 8 stable during spraying. By setting up the limiting baffle 45, it is easy to block the two sides of the spraying area. When the spraying component 64 is spraying at both ends, the escaping paint floats upward.

[0025] like Figure 3 and Figure 5 As shown, the middle position of the fixed base 51 corresponds to the middle position of the feed inlet of the spray box body 41. The two ends of the transmission rod 52 are rotatably connected to the fixed base 51 respectively. One end of the transmission rod 52 penetrates the spray box body 41 and is fixedly connected to the servo motor 53. One end of the fixed base 51 is rotatably connected to the support rod 54. The transmission rod 52 drives a pair of support rods 54 to rotate synchronously via a synchronous belt. The ends of the pair of support rods 54 that are close to each other are fixedly connected to support plates 55, and the sides of the support plates 55 that are far apart from each other are fixedly connected to a pair of second telescopic rods 56. Each of the output ends of the second telescopic rod 56 is fixedly connected to a clamping block 57. The clamping block 57 is slidably connected to the support plate 55. The openings on the sides of the clamping blocks 57 that are close to each other are in an outward-expanding shape.

[0026] The above solution is adopted: by setting up a clamping and flipping assembly 5, the transmission rod 52 and the servo motor 53 synchronously drive the support rod 54 to rotate, thereby realizing the synchronous rotation of the support plates 55 at both ends. The diffuser plate body 8 can be fixed and flipped at the same time, so that the diffuser plate body 8 can be easily flipped for double-sided cleaning and spraying. The second telescopic rod 56 and the clamping block 57 are set up so that the second telescopic rod 56 clamps the diffuser plate body 8 by pushing the clamping block 57.

[0027] like Figure 3 and Figure 6 As shown, the cleaning and spraying assembly 6 includes a guide rail 61 fixedly connected to the spraying box body 41 and two pairs of support rods 63 fixedly connected to the spraying box body 41. A sliding seat 62 is slidably connected in the middle of the guide rail 61, and the two pairs of sliding seats 62 are distributed on both sides of the clamping and flipping assembly 5. The middle part of the sliding seat 62 is slidably connected to the spraying component 64 and the cleaning component 65. The spraying component 64 is located on the lower side of the clamping and flipping assembly 5. The spraying component 64 includes a conveying pipe and a nozzle. The conveying pipe is connected to a paint conveying device, and the nozzle faces the spraying bracket 42 and the bottom of the nozzle is higher than the limiting baffle 45. The cleaning component 65 is located on the upper side of the clamping and flipping assembly 5. The cleaning component 65 includes two parts: an air supply pipe and a cleaning nozzle. The cleaning nozzle faces downward. An air supply device is connected to the air supply pipe. A coating curing lamp 7 is fixedly connected to the top of the inner wall of the spray box body 41 on the upper side of the cleaning component 65. The coating curing lamp 7 is perpendicular to the spray bracket 42.

[0028] The above solution is adopted as follows: by setting up the cleaning spraying component 6, the cleaning component 65 located on the upper side blows air to clean the diffuser plate body 8, and the dust blown down by the cleaning component 65 is sucked out through the suction port 44, thereby completing the cleaning of the diffuser plate body 8. At the same time, it can avoid dust floating and contaminating the spraying effect. The coating curing lamp 7 can cure the coating after the spraying is completed, avoiding damage to the coating by the clamping block 57 and the first telescopic rod 43.

[0029] Working principle and usage process of this invention: During transport, the diffuser plate body 8 is transported to the upper side of the transfer table 3 via the conveyor belt 2. The diffuser plate body 8 is completely moved to the top of the transfer table 3 via the conveyor in the middle of the transfer table 3, and the position of the diffuser plate body 8 is ensured by abutting against the limiting protrusion on one side of the transfer table 3. At the same time, the servo motor 53 drives the support rod 54 through the transmission rod 52 to rotate the support plate 55, so that the support plate 55 rotates to a vertical state. At this time, the transfer table 3 moves into the spray box body 41, bringing the diffuser plate body 8 into the spray box body 41 until it moves to the middle of a pair of support plates 55. At this time, the second telescopic rod 56 on the support plate 55 pushes the clamping block 57 to move to both sides, and the servo motor 53 starts the rotation and reset of a pair of support plates 55 through the transmission rod 52, so that the opened clamping block 57 flips to a horizontal state. At this time, the clamping block 57 will be located on both sides of the diffuser plate body 8. After the support plate 55 is reset, the sliding seat 62 will slide along the guide rail 61 to drive the cleaning component 65 to slide synchronously along the support rod 63, thereby cleaning the upper surface of the diffuser plate body 8. At the same time, the suction port 44 at the bottom of the spray box body 41 works synchronously to suck out the floating dust. After the cleaning component 65 completes one cleaning cycle, the second telescopic rod 56 will pull the clamping block 57 to close, thereby clamping and fixing the diffuser plate body 8. Then the transfer table 3 moves outward to reset. Then, the first telescopic rod 43 moves upward until it contacts the bottom of the diffuser plate body 8. The diffuser plate body 8 is then adsorbed through the suction port at the output end of the first telescopic rod 43. Then, the second telescopic rod 56 pushes the clamping block 57 to open, releasing the clamping of the diffuser plate body 8. The first telescopic rod 43 pulls the diffuser plate body 8 downward until it contacts the spraying bracket 42. At this time, the sliding seat 62 moves along the guide rail 61 again to drive the spraying component 64 to slide. The spraying component 64 moves to the top of the diffuser plate body 8 to perform the spraying operation, thus completing the spraying of one side. Then, the first telescopic rod 43 pushes the diffuser plate body 8 upward to the middle of the support plate 55. The coating of the diffuser plate body 8 is irradiated by the coating curing lamp 7 to complete the curing of the coating. Then, the clamping block 57 clamps the diffuser plate body 8 again and drives the diffuser plate body 8 to flip over, causing the diffuser plate body 8 to turn over. Then, the cleaning, spraying and curing steps are repeated. The transfer table 3 enters the spray box body 41 again and takes out the diffuser plate body 8.
