Description

Technical Field

[0001] This utility model relates to the field of diffusion plate production technology, and in particular to an engraving device for diffusion plate processing. Background Technology

[0002] The most significant characteristic of a diffuser plate is its ability to cause substantial light interference. Regardless of the original light distribution curve, once light passes through the diffuser plate, the beam angle will change to 160–176°. Therefore, when viewed from the side, the surface of the luminaire appears hazy, which is the best proof that the beam angle is as large as 160–176°. The larger the beam angle, the lower the illuminance. Some diffusers can also filter light, preventing some wavelengths from passing through and causing color shift. If further light interference is applied to the surface, the transmittance will be even lower due to the natural phenomena of geometric optics. Therefore, the substrate used to make diffusers should have the lowest possible refractive index to minimize light interference.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A carving device for processing diffusion plates includes a worktable 1, a movable frame 2 on the worktable 1, the movable frame 2 being movable along the front-to-back direction of the worktable 1, a movable block 3 on the movable frame 2, the movable block 3 being movable along the left-to-right direction of the worktable 1, a carving head 4 on the movable block 3, a bidirectional lead screw 5 rotatably connected to the bottom wall of the worktable 1, the bidirectional lead screw 5 being driven by a first servo motor 6, the first servo motor 6 being located on the side wall of the worktable 1, both ends of the bidirectional lead screw 5 being threadedly connected to movable rods 7, the tops of the two movable rods 7 passing through the worktable 1 and connected to clamping plates 8, the two clamping plates 8 being arranged opposite to each other, a controller 9 being located on the side wall of the worktable 1, the movable frame 2 and the movable block 3 being controlled to move by the controller 9, the first servo motor 6 and the carving head 4 being electrically connected to the controller 9.

[0018] When using the device, the diffuser plate is placed between the two clamping plates 8. The controller 9 controls the first servo motor 6 to run, thereby driving the bidirectional lead screw 5 to rotate. This, in turn, drives the two moving rods 7 to move the corresponding clamping plates 8 closer to each other, thus achieving the clamping and fixing of the diffuser plate. Afterward, the controller 9 controls the moving frame 2 and the moving block 3 to move, so that the engraving head 4 moves to the desired engraving position. The engraving head 4 then runs, thereby achieving the engraving work on different positions and shapes on the diffuser plate.

[0019] Specifically, in this embodiment, rubber pads are provided on both clamping plates 8, and a moving groove 10 is provided on the worktable 1. Two moving rods 7 are adapted to fit through the moving groove 10 and pass through the worktable 1. The rubber pads are provided to protect the diffuser plate during clamping and prevent wear. The moving groove 10 restricts the movement direction of the moving rods 7, ensuring that the moving rods 7 drive the two clamping plates 8 to always move in the horizontal direction.

[0020] Specifically, in this embodiment, a pressure sensor 11 is provided on one of the clamping plates 8, and the pressure sensor 11 is electrically connected to the first servo motor 6. The setting of the pressure sensor 11 facilitates real-time monitoring of the force on the clamping plate 8. When the detected value is the same as the set value, the first servo motor 6 is triggered to stop working, so that the clamping force applied by the clamping plate 8 to the diffuser plate is within an appropriate range, which can both clamp the diffuser plate tightly and avoid damage to the diffuser plate due to excessive force.

[0021] Specifically, in this embodiment, a support 12 is provided on one side of the workbench 1, and a camera 13 is mounted on the support 12. The camera 13 is electrically connected to the controller 9. Through the connection between the camera 13 and the controller 9, it is convenient to identify the position to be engraved on the diffuser plate through the camera 13. The controller 9 sends instructions to adjust the position of the moving frame 2 and the moving block 3 so that the engraving head 4 can be accurately moved to the position to be engraved.

[0022] Specifically, in this embodiment, the bottom end of the moving block 3 is connected to an electric telescopic rod 14, and the telescopic end of the electric telescopic rod 14 is connected to a device frame 15. The engraving head 4 is installed on the bottom wall of the device frame 15, so that the device can adjust the distance between the engraving head 4 and the diffuser plate by operating the electric telescopic rod 14, thereby achieving the purpose of engraving diffuser plates of different thicknesses.

[0023] Specifically, in this embodiment, a dust collection box 16 is detachably installed inside the device frame 15. The dust collection box 16 is connected to a dust suction structure 17 via a retractable hose, so that the dust suction structure 17 can operate synchronously when the engraving work is in progress, absorbing the dust generated during engraving and transporting it to the dust collection box 16 through the retractable hose, thereby achieving synchronous dust cleaning.

[0024] Specifically, in this embodiment, a second servo motor 18 is provided on the device frame 15. The output end of the second servo motor 18 is connected to an L-shaped connecting rod 19. The bottom end of the L-shaped connecting rod 19 is connected to the dust collection structure 17, so that the second servo motor 18 can drive the dust collection structure 17 to rotate in a range of less than 360° in the forward or reverse direction through the L-shaped connecting rod 19, so as to adjust the orientation of the dust collection mechanism 17 in real time according to the dust distribution, thereby improving the dust cleaning efficiency.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
