[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] In actual use, the different sizes and shapes of the workpieces lead to instability when fixing them, resulting in uneven coating on the workpiece surface. Consequently, the reflective film has a high reflectivity, and the product quality is unstable, failing to meet production requirements.

[0021] In view of this, the present invention provides an ultra-low reflectivity film surface coating device, which solves the problem that in actual use, due to the different sizes and shapes of the workpieces, the workpieces are unstable when fixed, resulting in uneven coating effect on the workpiece surface, which in turn leads to high reflectivity of the reflective film, unstable product quality, and inability to meet production needs.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4It is known that an ultra-low reflection film surface coating device includes a worktable 1, a plurality of rollers 2 rotatably connected to the inner wall of the worktable 1, and a coating head 6 arranged above the rollers 2. The ultra-low reflection film surface coating device also includes a fixing device 3, a moving device 4, and a front-to-back moving assembly 5. The fixing device 3 is installed on the top of the worktable 1; the moving device 4 is installed on the top of the coating head 6; and the front-to-back moving assembly 5 is installed on the top of the worktable 1. The workpiece is fixed by the fixing device 3, the moving device 4 drives the coating head 6 to move, and the front-to-back moving assembly 5 drives the coating head 6 to move back and forth.

[0024] In the specific implementation process, it is worth noting that the rotation of roller 2 makes it convenient for workers to install workpieces, and the model of coating head 6 is not limited as long as it meets the actual use requirements. When coating the workpiece, the fixing device 3 is used to fix the workpiece so that the workpiece is coated with reflective film evenly, while the moving device 4 will drive the coating head 6 to move above the workpiece, so that the coating head 6 can accurately coat the workpiece with reflective film. Under the drive of the front and rear moving components 5, the coating area of ​​the coating head 6 is larger, thereby increasing the overall practicality of the coating device.

[0025] Furthermore, the fixing device 3 includes a pressure plate 31, a fixing block 32, a spring 33, a plug rod 34, a fixing frame 35, and an adjusting assembly 36. The pressure plate 31 is positioned above the roller 2; the fixing block 32 is installed on the top of the pressure plate 31; the spring 33 abuts against the top of the fixing block 32; the plug rod 34 is fixedly connected to the top of the fixing block 32 and inserted into the inner wall of the spring 33; the fixing frame 35 is sleeved on the outer wall of the plug rod 34 and abuts against the top of the spring 33, and its bottom is fixedly connected to the top of the worktable 1; the adjusting assembly 36 is installed between the pressure plate 31 and the fixing block 32. Through the cooperation of the spring 33 and the fixing block 32, the installed pressure plate 31 fixes the workpiece; the plug rod 34 stabilizes the pressure plate 31 during movement; the fixing frame 35 supports the plug rod 34; and the adjusting assembly 36 adjusts the position of the pressure plate 31.

[0026] In the specific implementation process, it is worth noting that the pressure plate 31 is elongated and a rubber pad is installed at the bottom of the pressure plate 31. This prevents damage to the workpiece when the pressure plate 31 is used to fix it. A spring 33 is provided between the fixing block 32 and the fixing frame 35. The elastic force of the spring 33 will compress the pressure plate 31 and the fixing frame 35. When the pressure plate 31 and the fixing frame 35 are used to fix the workpiece, the pressure plate 31 will drive the fixing block 32 to compress the spring 33, thereby making the pressure plate 31 stable when fixing the workpiece. In addition, the outer wall of the insertion rod 34 is provided with a protrusion, which can stabilize the insertion rod 34 when the fixing block 32 drives it to move within the fixing frame 35.

[0027] Furthermore, the adjustment component 36 includes a slide groove 361 and a slider 362. The slide groove 361 is formed on the top of the pressure plate 31; the slider 362 is slidably engaged with the inner wall of the slide groove 361, and its top is fixedly connected to the bottom of the fixing block 32; wherein, the position of the pressure plate 31 is adjusted by the cooperation of the slide groove 361 and the slider 362.

[0028] In the specific implementation process, it is worth noting that when fixing workpieces of different sizes, the operator pushes the pressure plate 31 to move, so that the slide groove 361 moves on the outer wall of the slider 362, thereby enabling the pressure plate 31 to be accurately fixed to the workpiece, thus increasing the practicality of the device. Furthermore, the slider 362 is trapezoidal in shape, and the slide groove 361 at the top of the pressure plate 31 is also trapezoidal in shape, making it convenient to adjust the pressure plate 31.

[0029] Example 2: From Figure 1-4 It is known that the moving device 4 includes a mounting frame 41, a horizontal plate 42, a gear 43, a fixed shell 44, a servo motor 45, and a limiting block 46. The mounting frame 41 is mounted on the top of the workbench 1; the horizontal plate 42 is fixedly connected to the top of the mounting frame 41; the gear 43 is meshed with the top of the horizontal plate 42; the fixed shell 44 is rotatably connected to the outer wall of the gear 43 via a pin, and its inner wall is movably connected to the outer wall of the horizontal plate 42; the servo motor 45 is fixedly connected to the outer wall of the fixed shell 44, and its output end is fixedly connected to the outer wall of the gear 43 via a sealed bearing passing through one end of the fixed shell 44; the limiting block 46 is fixedly connected to the bottom of the inner wall of the fixed shell 44 and slidably engaged with the bottom of the horizontal plate 42; wherein, through the cooperation of the mounting frame 41 and the horizontal plate 42, the fixed shell 44 and the gear 43 drive the coating head 6 to move, the servo motor 45 drives the gear 43 to rotate, and the limiting block 46 stabilizes the fixed shell 44 during movement;

[0030] In the specific implementation process, it is worth noting that the top of the horizontal plate 42 is provided with teeth that can mesh with the gear 43 inside the fixed shell 44. When the servo motor 45 drives the gear 43 to rotate, the gear 43 will mesh with the horizontal plate 42, causing the fixed shell 44 to move on the outer wall of the horizontal plate 42, and the coating head 6 to move above the workpiece, making it convenient to coat. When the fixed shell 44 moves, it will drive the limit block 46 to slide at the bottom of the horizontal plate 42, which can make the fixed shell 44 stable when moving. Furthermore, the model of the servo motor 45 is not limited, as long as it meets the actual use.

[0031] Furthermore, the forward and backward moving assembly 5 includes an electric slide bar 51 and an electric slider 52. The electric slide bar 51 is mounted on the top of the worktable 1; the electric slider 52 is fixedly connected to the bottom of the mounting bracket 41 and movably connected to the outer wall of the electric slide bar 51; wherein, through the cooperation of the electric slider 52 and the electric slide bar 51, the coating head 6 moves forward and backward.

[0032] In the specific implementation process, it is worth noting that the electric slide bar 51 and the electric slider 52 are used together. When adjusting the position of the coating head 6, the electric slider 52 will move on the outer wall of the electric slide bar 51, so that the mounting frame 41 drives the coating head 6 to move back and forth, so that the reflective film on the upper surface of the workpiece is coated more evenly. In summary, the model of the electronic components is not limited, as long as it meets the actual use.

[0033] Furthermore, an electric telescopic rod 7 is fixedly connected to the bottom of the fixed housing 44, and the output end is fixedly connected to the top of the coating head 6;

[0034] In the specific implementation process, it is worth noting that when the coating head 6 coats the workpiece, the electric telescopic rod 7 will drive the coating head 6 to move downward, so that the coating height of the coating head 6 can contact the surface of the workpiece, thereby ensuring that the reflective film on the surface of the workpiece is evenly coated. The model of the electric telescopic rod 7 is not limited, as long as it meets the actual use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
