Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, specifically to a coating device for a multi-faceted radar rotating mirror. Background Technology
[0002] The multi-faceted radar rotating mirror (also known as a multi-faceted rotating scanning mirror) is the core component of lidar. It achieves three-dimensional scanning by reflecting laser beams at high speed. Its function is that the multi-faceted rotating mirror is essentially a polygonal cylinder with a reflective layer coated on its sides.
[0003] Evaporation coating is performed in a vacuum environment, where the coating material is vaporized through methods such as resistance heating, electron beam heating, or laser heating. The gaseous particles migrate in a straight line to the substrate surface in a vacuum. Evaporation coating is characterized by simple equipment and low cost, making it suitable for applications requiring high purity, such as optical components (e.g., mirrors) and conductive films. However, for multi-faceted radar mirrors, due to their varied shapes, sizes, and surface areas, mainstream planar coating machines cannot meet the requirements for film uniformity. Therefore, planetary coating equipment used for manufacturing curved products must be employed.
[0004] Existing multi-faceted radar mirrors generally require coating on a rotating planetary disk to achieve uniform coating and better film density. However, due to the small size of multi-faceted radar mirrors, the sides need to be coated and the inner area needs to be shielded. Furthermore, the planetary disk mechanism has a low transfer rate and the emission source angle is fixed, resulting in low output, significant film color variation, and a low yield, which directly affects the objective problem of production cost.
[0005] To address the limitations in selecting and using coating equipment for existing multi-faceted radar rotating mirrors and to increase actual production output, a coating device for multi-faceted radar rotating mirrors is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a coating device for a multi-faceted radar rotating mirror.
[0007] This utility model provides the following technical solution:
[0008] This utility model proposes a coating device for a multi-faceted radar rotating mirror, including a coating umbrella frame and a through-hole conductive slip ring for installation in the cavity of a coating machine. The coating umbrella frame is fixed to the lower end of the through-hole conductive slip ring, and a coating tooling is provided on the coating port on the coating umbrella frame.
[0009] The coating fixture includes a perforated base plate disposed on the coating port. A pair of parallel motors are fixed on one side of the perforated base plate. The output shaft of the motors is connected to a pin screw. Multiple shielding plates for shielding the upper and lower surfaces of the multi-faceted radar mirror are inserted through the pin screw. A nut for fastening the shielding plates and the multi-faceted radar mirror is also inserted through the pin screw. The end of the pin screw is disposed in a bearing, and the bearing is fixed on the perforated base plate on the side opposite to the motors.
[0010] Furthermore, it also includes an integrated junction box disposed on the coated umbrella frame and a plurality of terminals connected to the power supply of the integrated junction box, each terminal corresponding to each of the coating ports; the terminals are fixed on the coated umbrella frame and are on the same side as the motors, supplying power to a pair of motors.
[0011] Furthermore, the upper surface of the through-hole conductive slip ring has an input power port, and the lower surface of the through-hole conductive slip ring has an output power port.
[0012] Furthermore, the through-hole conductive slip ring includes an outer ring for fixing to the inside of the coating machine and an inner ring disposed within the outer ring, with the lower end of the inner ring protruding outside the outer ring; the top of the coating umbrella frame is locked and fixed to the inner ring by screws.
[0013] Furthermore, the hollow base plate includes a U-shaped plate and a connecting plate, the connecting plate connecting the two ends of the U-shaped plate with screws; the motor is fixed on the U-shaped plate, and the bearing is fixed on the connecting plate.
[0014] Furthermore, the bearing and the ejector pin screw are connected by a screw shaft joint.
[0015] Furthermore, the output shaft of the motor and the ejector pin screw are connected via a spindle connector.
[0016] Furthermore, the motor is a high-temperature vacuum stepper motor.
[0017] Compared with the prior art, this utility model has a simple structure and is easy to use. When installed in a coating machine, the product is rotated by a motor, achieving coating on all sides of the product and uniformity of the film layer. This improves the utilization rate of the equipment, enables the equipment to be compatible with the production of various products, increases production capacity, greatly improves output value and efficiency, and provides a major guarantee for more effective production activities.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] See Figure 1 and Figure 2 In one embodiment of the present invention, a coating device for a multi-faceted radar rotating mirror includes a coating umbrella frame 1 and a through-hole conductive slip ring 2 for installation in the cavity of a coating machine. The coating umbrella frame 1 is fixed at the lower end of the through-hole conductive slip ring 2, and a coating fixture 3 is provided on the coating port 11 on the coating umbrella frame 1.
[0027] The coating fixture 3 includes a perforated base plate 31 disposed on the coating port 11. A pair of parallel motors 32 are fixed on one side of the perforated base plate 31. The output shaft of the motors 32 is connected to a pin screw 33. Multiple shielding plates 34 for shielding the upper and lower surfaces of the multi-faceted radar mirror 00 are passed through the pin screw 33. A nut 35 for fastening the shielding plates 34 and the multi-faceted radar mirror 00 is also passed through the pin screw 33. The end of the pin screw 33 is disposed in a bearing 36. The bearing 36 is fixed on the perforated base plate 31 on the side opposite to the motors 32.
[0028] It is worth mentioning that the multi-faceted radar rotating mirror 00 itself has a central through hole, and the ejector pin screw 33 is installed through the central through hole of the multi-faceted radar rotating mirror 00.
[0029] In the above technical solution, the multi-faceted radar mirrors 00 of the shielding plates 34 are stacked alternately, so that the shielding plates 34 block the inner area (top and bottom surfaces) of the multi-faceted radar mirrors 00, and are strung together with ejector pins 33. Then, the nuts 35 are tightened by hand to fix them. Then, the end of the ejector pin 33 is inserted into the bearing 36, and the coating device with the product 00 installed is installed in the coating machine for coating. During the coating process of the coating machine on the product 00, the motor 32 drives the ejector pin 33 to rotate, which in turn drives the product 00 to rotate, so as to achieve coating on multiple sides of the product 00.
[0030] It is worth mentioning that this device itself does not have coating capabilities; it needs to be installed inside a coating machine to perform coating.
[0031] See Figure 1 and Figure 6 In one embodiment of the present invention, the four corners of the coating port 11 each have a protrusion 12 for placing the hollow base plate 31.
[0032] See Figure 1 In one embodiment of this utility model, it further includes an integrated junction box 4 disposed on the coated umbrella frame 1 and a plurality of wiring terminals 5 that are powered by the integrated junction box 4. Each wiring terminal 5 corresponds to each of the coated ports 11. The wiring terminals 5 are fixed on the coated umbrella frame 1 and are on the same side as the motor 32, supplying power to a pair of motors 32.
[0033] See Figure 4 In one embodiment of this utility model, the upper surface of the through-hole conductive slip ring 2 has an input power port 21, and the lower surface of the through-hole conductive slip ring 2 has an output power port 22. In practical applications, the input power port 21 is connected to the internal power supply of the coating machine; the output power port 22 supplies power to the motor 32.
[0034] In one embodiment of this utility model, the output power port 22 is connected to the integrated junction box 4, and the integrated junction box 4 is connected to each terminal 5 to supply power to the motor 32.
[0035] Please continue reading. Figure 4 and Figure 5 In one embodiment of the present invention, the through-hole conductive slip ring 2 includes an outer ring 23 for fixing to the inside of the coating machine and an inner ring 24 disposed within the outer ring 23, and the lower end of the inner ring 24 is exposed outside the outer ring 23; the top of the coating umbrella frame 1 is locked and fixed to the inner ring 24 by screws.
[0036] In the above technical solution, the coated umbrella frame 1 is installed inside the inner ring 24 and fixed with screws.
[0037] See Figure 5 The output power port 22 is located on the lower surface of the inner ring 24.
[0038] In one embodiment of this utility model, the hollow base plate 31 includes a U-shaped plate 311 and a connecting plate 312. The connecting plate 312 connects the two ends of the U-shaped plate 311 by screwing screws into screw holes 39. The motor 32 is fixed on the U-shaped plate 311, and the bearing 36 is fixed on the connecting plate 312.
[0039] In the above technical solution, the motor 32 is always fixed on the U-shaped plate 311, and the bearing 36 is always fixed on the connecting plate 312. However, when the product 00 is inserted into the ejector screw 33 or removed from the ejector screw, the connecting plate 312 (screw out the screw on the threaded hole 39) needs to be removed.
[0040] See Figure 3 In one embodiment of this utility model, the bearing 36 and the ejector pin 33 are connected by a screw shaft joint 37, making the connection more stable and secure.
[0041] Please continue reading. Figure 3 In one embodiment of this utility model, the output shaft of the motor 32 and the ejector screw 33 are connected by a main shaft connector 38, making the connection more stable and secure.
[0042] See Figure 2 In one embodiment of this utility model, the motor 32 is a high-temperature vacuum stepper motor; ensuring normal operation under vacuum and high temperature conditions.
[0043] It is worth mentioning that the electrical connections in this utility model are all conventional connections and do not involve the disclosure of circuits, so they will not be described in detail. This utility model only protects the structure.
[0044] Working principle: This device is installed in a coating machine for coating. The rotation of the motor drives the ejector screw 33 to rotate, which in turn drives the shielding baffle 34 fixed on the ejector screw 33 and the multi-faceted radar mirror 00 to rotate, so as to achieve uniform coating on all sides of the multi-faceted radar mirror 00.
[0045] Product installation method: Alternately stack the shielding plate and the multi-faceted radar mirror, so that the shielding plate covers the inner area (top and bottom) of the multi-faceted radar mirror. Thread the product and the shielding plate together through the center through hole of the product using a pin screw, and tighten the product and the shielding plate onto the pin screw by hand-tightening the nut. Insert the end of the pin screw into the screw shaft joint fixed in the bearing, and finally lock the connecting plate onto the U-shaped plate with screws.
[0046] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
