Description

Technical Field

[0001] This utility model relates to the field of radar radome coating technology, and in particular to an external physical vapor deposition device for lidar. Background Technology

[0002] Currently, common lidar covers on the market, designed for use in small devices, typically employ small spherical covers as the lidar carrier. These covers utilize a novel hemispherical arc shape and are injection-molded from infrared-transparent polycarbonate (PC) material, achieving high near-infrared transmittance and low reflectivity. To further enhance the radar's infrared transmittance, an anti-reflection coating is applied to the lidar surface. Current coating methods primarily employ spherical coating machines. During the coating process, one planetary gear of the coating equipment holds one lidar. The uniformity of the coating on the part's surface is achieved through the equipment's revolution and the planetary gear's rotation. This method requires coating each lidar individually, consuming significant time and cost. Therefore, we have designed an external physical vapor deposition (PVD) device for lidar. Using a three-way fixture fixed to the planetary gears, this increases the number of full-furnace loads and improves coating efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an external physical vapor deposition device for lidar, which increases the number of full furnaces for coating and improves coating efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention proposes an external physical vapor deposition device for lidar, including a planetary disk. The planetary disk is provided with a product fixture for placing products. The product fixture has a limiting groove for limiting the bottom of the product. A fixing hole for fixing the product head is opened on one side of the limiting groove.

[0006] Furthermore, the product tooling consists of three units arranged in an array around the periphery of the planetary disk.

[0007] Furthermore, the planetary disk is made of stainless steel.

[0008] Furthermore, the tooling used in the product is made of aluminum alloy.

[0009] Furthermore, the planetary disk is provided with clearance holes for avoiding the coating equipment.

[0010] Furthermore, there are four clearance holes arranged in an array around the periphery of the planetary disk.

[0011] The beneficial effects of this utility model are as follows: by fixing three product fixtures on the planetary gear, it is possible to perform trial plating and coating on three products at the same time, which improves the coating efficiency and saves a lot of time and cost. At the same time, through the revolution of the coating equipment and the rotation of the planetary gear, uniform coating can be achieved on the products on the product fixture.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please see Figures 1 to 2 This utility model provides an embodiment:

[0017] Please see Figure 1 and Figure 2 An external physical vapor deposition device for lidar includes a planetary disk 1, a product fixture 2 for placing a product 6 on the planetary disk 1, a limiting groove 3 for limiting the bottom of the product 6 on the product fixture 2, and a fixing hole 4 for fixing the head of the product 6 on one side of the limiting groove 3.

[0018] Please see Figure 1 Product tooling 2 consists of 3 units, and the array is set around the planetary disk 1.

[0019] Please see Figure 1 Planetary disk 1 is made of stainless steel. The use of stainless steel in planetary disk 1 provides it with corrosion resistance and makes it easier to clean.

[0020] Please see Figure 1 The product fixture 2 is made of aluminum alloy. Using aluminum alloy for product fixture 2 can reduce the overall weight of the fixture, reduce energy consumption during rotation, and prevent rust and other foreign objects from contaminating product 6.

[0021] Please see Figure 1 and Figure 2The planetary disk 1 has a clearance hole 5 for avoiding the coating equipment. The coating equipment has protruding fixing screws. When it gets close to the planetary disk 1, the fixing screws will touch the planetary disk 1. The clearance hole 5 on the planetary disk 1 can avoid the position of the fixing screws and avoid affecting the normal operation of the planetary disk 1.

[0022] Please see Figure 1 There are four clearance holes 5 arranged in an array around the periphery of the planetary disk 1.

[0023] Working principle: The operator wears latex gloves (or finger cots) and a mask to avoid touching the optical surface of product 6. Then, the bottom of product 6 is placed on the limiting groove 3 of product fixture 2, so that product 6 is set on product fixture 2 without moving. At the same time, product 6 is rotated so that the mounting hole of product 6 aligns with the fixing hole 4 opened on product fixture 2. The mounting hole and fixing hole 4 are fixed with screws 7 to fix product 6 and prevent it from loosening. Planetary disk 1 uses a strong magnet to attract product fixture 2, and the operator can then perform trial plating. If the trial plating index is met, product fixture 2 and planetary disk 1 are attracted again by a strong magnet to perform formal coating, completing the simultaneous coating of 3 products 6.
