Description

Technical Field

[0001] This invention relates to the field of radar probe manufacturing equipment technology, specifically to an integrated radar painting device. Background Technology

[0002] Miniature radar probes are compact radar sensors typically used for short-range detection, obstacle avoidance, motion detection, and speed measurement. They are characterized by their small size, low power consumption, and high integration, making them suitable for drones, robots, smart homes, and automotive driver assistance systems. Radar probes require painting to improve their surface weather resistance and abrasion resistance, thereby extending their lifespan. To improve efficiency, multiple radar probes are often painted simultaneously. Currently, adhesive-based fixtures are commonly used to attach the probes for painting. However, this method of fixation can lead to… Paint accumulates at the end of the radar probe where it is bonded, forming lumps that require subsequent removal, which is very inconvenient. To address this, Chinese utility model patent CN206652647U discloses a radar probe painting fixture. It includes a paint spraying plate with several through holes A, and slide rails on both sides of the plate. The paint spraying plate and slide rails are fixedly connected. A movable pressure plate is mounted on the slide rails, and the pressure plate has several through holes B, each corresponding to one of the through holes A. The radar probe end is secured using these two through holes, eliminating the need for traditional adhesive bonding. However, the following drawbacks still exist during painting:

[0003] Using this type of tooling, multiple radar probes can be painted in batches at the same time. However, there will be obstruction between each radar, which will cause blind spots when painting. In order to ensure the painting effect, excessive paint needs to be applied, resulting in uneven paint on the surface of the radar probe after painting, which affects the painting quality.

[0050] Example 3:

[0051] Please see Figure 1-14This is the third embodiment of the present invention, based on the above two embodiments. In use, the cleaned and rust-removed radar probe workpiece is installed onto the workpiece fixing assembly 2. During installation, the radar probe workpiece wiring terminal is inserted into the rubber inner sleeve 24, and the set screw 214 is tightened for fixation. Then, the workpiece fixing assembly 2 is placed on the chain conveyor line 11 for transport. The chain conveyor line 11 uses an intermittent transport method. When the workpiece reaches the position of the first workpiece moving mechanism 3, the workpiece gripping assembly 38 on the first workpiece moving mechanism 3 moves to the chain conveyor line 11 and grips one workpiece fixing assembly 2. The workpiece fixing assembly 2 is then moved to the grinding seat 12. After adjusting the direction of the workpiece fixing assembly 2, the side strip 218 on the workpiece fixing assembly 2 is inserted into the strip groove 13 of the grinding seat 12 to stabilize it. Then, the sanding belt 48 in the grinding assembly 4 moves down to press and clamp multiple radar probe workpieces for grinding. During grinding, the fourth servo reduction motor 387 drives the radar probe workpiece to rotate to different surfaces for grinding, improving the surface roughness of the radar probe workpiece. Then, the process continues... The workpiece is returned to the conveyor belt 11 and transported to the second workpiece moving mechanism 3. The workpiece gripping component 38 then grips the workpiece fixing component 2 and moves it to the painting component 5 for primer spraying. During spraying, the fourth servo reduction motor 387 drives multiple radar probe workpieces to rotate synchronously and slowly at a uniform speed. After the primer is applied, the topcoat is sprayed, completing the painting operation. This invention utilizes the workpiece fixing component 2 to fix multiple radar probe workpieces, enabling batch painting with high efficiency. The radar probe workpieces are fixed by inserting their ends into the rubber inner sleeve 24 using a sleeve connection. Multiple first synchronous belts 27 allow multiple radar probe workpieces to rotate synchronously. After the workpiece gripping component 38 grips the workpiece fixing component 2, the spline head 388 inserts into the spline groove 29. The fourth servo reduction motor 387 then drives the drive shaft 28 to rotate, thereby causing multiple radar probe workpieces to rotate synchronously and uniformly. This allows for even spraying of all surfaces of the radar probe workpieces during the painting operation, resulting in more uniform spraying and saving paint by avoiding excessive spraying.
