[0002] Coating the pyramids can reduce stray light, improve image clarity, enhance reflectivity, and protect optical components.

[0003] Conventional corner cone coating processes typically involve clamping and fixing the corner cone in a fixture and placing it in an electroplating bath for coating. Alternatively, there are methods where the corner cone is placed directly in the electroplating bath for coating.

[0004] However, regardless of which method is used, the pyramid requires a support surface, and the coating on this support surface may be uneven.

[0005] Therefore, it is necessary to propose an apparatus for cone coating to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a device for coating a corner cone, so as to solve the problem of uneven coating on the support surface of the corner cone.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an apparatus for coating a cone, comprising an electroplating tank, wherein a lifting mesh frame is provided in the electroplating tank, the lifting mesh frame is used to place the cone, and the four sides and bottom surface of the lifting mesh frame are all grid mesh structures;

[0008] The lifting frame moves up and down repeatedly in the electroplating tank. As the lifting frame moves up and down, the cone follows the lifting frame as it rises or falls. During the descent of the cone, it is suspended in the electrolyte inside the electroplating tank to achieve uniform coating.

[0009] Preferably, an electric cylinder is installed on the side of the electroplating tank. The electric cylinders are vertically distributed, and an upper support plate is connected to the upper end of the electric cylinder.

[0017] 2. In the device for cone coating of this utility model, during the lifting and lowering of the lifting mesh frame, the electrolyte in the electroplating tank will also pass through the grid mesh structure and will not be carried away by the lifting mesh frame.

[0018] 3.

[0023] This utility model provides an apparatus for coating a cone, as shown in Figures 1-3, which can achieve uniform coating of the cone.

[0024] A pyramid, also known as a tetrahedron, is a geometric shape consisting of a polygonal base and triangular lateral faces connected to its vertices.

[0025] In mechanical engineering, pyramids are primarily used to transmit power and torque; however, they are also commonly used in optics, typically as pyramidal prisms. A pyramidal prism is an optical element used to reflect light, possessing three reflective surfaces that act as retroreflectors, enabling incident light to return almost entirely along its original path. This characteristic makes pyramidal prisms widely used in laser ranging, laser tracking, optical communication, and scientific research. For example, in laser ranging, pyramidal prisms are used to accurately measure distances; in laser tracking systems, they are used to achieve precise tracking and positioning of target objects; and in optical communication, they are used for the stable transmission of optical signals.

[0026] The device for coating corner cones in this invention can reduce stray light, improve imaging clarity, enhance reflectivity, and protect optical components after coating corner cones.

[0027] However, conventional corner cone coating processes usually involve clamping and fixing the corner cone with a fixture and placing it in an electroplating bath for coating, or there are methods where the corner cone is placed directly in the electroplating bath for coating.

[0028] However, regardless of the method mentioned above, the pyramid requires a supporting surface, and the coating on this supporting surface may be uneven. Therefore, this invention proposes a device for coating pyramids, which can achieve uniform coating on all surfaces of the pyramid with high efficiency.

[0029] Specifically, referring to Figure 1, the device for cone coating includes an electroplating tank 1, in which an electrolyte is placed. Positive and negative electrodes for electrolysis are also installed on both sides of the electroplating tank 1. It is a conventional electroplating device and will not be described in detail here.

[0030] The electroplating tank 1 contains a lifting mesh frame 2, the height of which is greater than that of the electroplating tank 1. The lifting mesh frame 2 has an opening at the top, and its sides and bottom are made of a grid mesh structure. During the coating process, the cone is placed directly in the lifting mesh frame 2, which is then submerged in the electroplating tank 1 for electroplating. During the electroplating process, the lifting mesh frame 2 moves up and down reciprocally. As the lifting mesh frame 2 rises, the cone rises with it. As the lifting mesh frame 2 descends, the cone needs to overcome the buoyancy of the electrolyte, so the descent speed of the cone is lower than that of the lifting mesh frame 2, resulting in the cone being suspended in the electrolyte. When the cone is suspended in the electrolyte, its outer surface can be uniformly coated. This process of lifting and lowering the lifting mesh frame 2 is repeated until the coating of the cone is completed, forming a uniform coating layer on the surface of the cone.

[0031] Furthermore, during the lifting process of the lifting mesh frame 2, the electrolyte in the electroplating tank 1 will also pass through the grid mesh structure and will not be carried away by the lifting mesh frame 2.

[0032] Referring to Figure 2, a filter screen 11 is also provided on the upper layer of the lifting frame 2. The surface of the filter screen 11 is provided with many filter holes, which penetrate both the upper and lower surfaces of the filter screen 11. The filter screen 11 is detachable. When the filter screen 11 is removed, the cone can be inserted into the lifting frame 2 from above, and then the filter screen 11 can be installed. During the up-and-down movement of the lifting frame 2, the filter screen 11 will also block the cone, preventing the cone from accidentally leaking out from above the lifting frame 2. Furthermore, when the cone coating is completed and the next batch of cones is coated, the cones that have been coated in the previous batch can be temporarily placed on the filter screen 11 to drain, so that the excess electrolyte can remain in the electroplating tank 1 without waste. The height of the filter screen 11 is set appropriately. When the lifting frame 2 descends to the bottom of the electroplating tank 1, the filter screen 11 is still above the electrolyte surface. The up-and-down movement of the lifting frame 2 also accelerates the drainage efficiency of the cone.

[0033] Referring to Figure 3, in actual use, a limit block 13 is installed at a suitable position on the inner wall of the lifting frame 2 using screws or other means. The asphalt mesh 11 sits directly on the limit block 13, which is convenient for installation. Each of the four corners of the upper surface of the asphalt mesh 11 is connected to a lifting ring 12, which is used to connect cables. An electric hoist or other mechanism is set above the device used for cone coating to connect the cables, which can complete the lifting and lowering operation of the asphalt mesh 11. The lifting is carried out in a completely electric manner, which is simple and efficient.

[0034] Referring to Figures 1 and 2, a fixed base 8 is installed in the middle of the side of the electroplating tank 1. An electric cylinder 3 is installed above the fixed base 8. The electric cylinder 3 is used to drive the lifting screen frame 2 to move up and down repeatedly. A vertical lug 7 is fixedly welded at each of the four corners of the upper surface of the lifting screen frame 2. A connecting plate 6 is fixedly installed at the upper end of the vertical lug 7. The two connecting plates 6 on the same side of the electroplating tank 1 are connected by an upper support plate 5. The upper end of the electric cylinder 3 is installed in the middle of the bottom surface of the upper support plate 5. When the electric cylinder 3 is started, the electric cylinder 3 can drive the lifting screen frame 2, the vertical lug 7, the connecting plate 6 and the upper support plate 5 to move up and down as a whole.

[0035] Sliding rails 9 are installed on both sides of the electroplating tank 1. Sliding blocks 10 are slidably arranged in the sliding rails 9. The sliding blocks 10, the upper support plate 5 and the connecting plate 6 are fixed together by the same long screw 4. Nuts are installed on the long screw 4 to achieve the purpose of fixed connection. When the lifting screen frame 2 is lifted, the sliding blocks 10 slide up and down in the sliding rails 9 to play a guiding and stabilizing role.
