[0002] In the process of transitioning from "semi-automation" to "full automation," fully automated welding technology has become a new variable in the development of the radar industry. The processing of fully automated welding equipment loading and unloading systems cannot be achieved without various updates and transformations. For example, the four major hardware sensors—vehicle cameras, millimeter-wave radar, lidar, and ultrasonic radar—are the eyes of autonomous vehicles, providing crucial information for environmental perception.

[0003] Radar welding loading and unloading equipment is increasingly used in automated production lines in industrial manufacturing. To meet the requirements of production lines moving from semi-automation to full automation, it is necessary to manufacture advanced, fully automated radar welding loading and unloading equipment that reduces manual labor, offers high speed, and high efficiency. This necessitates improving the portable structure of the equipment for easier manual operation, making it compact for mass production. The full automation transformation of radar welding loading and unloading systems represents a turning point in the structural upgrading of many welding product equipment, playing a crucial role in the transition from semi-automatic to fully automated radar welding loading and unloading structures.

[0004] Existing automatic welding equipment for vehicle radar housings often produces a lot of metal spatter during the welding process. Metal spatter is dangerous and can easily affect the working environment. In addition, if the welding process parameters are not matched properly, the welding quality can be affected. Therefore, an automatic welding equipment for vehicle radar housings is needed to solve the above problems. Utility Model Content

A laser welding head 12 is fixedly installed below, which can weld the material. A camera system 13 is installed on the surface of the upper and lower material trays 11 near one end, which can capture images of the material. A fixture rotation mechanism 14 is fixedly installed on the top of the floor 1 near the center, which can automatically rotate the rotating tray 90 degrees after the fixture and product are welded. A gripping robot 16 is fixedly installed on the top of the floor 1 and on one side of the fixture rotation mechanism 14, which can grip the material. A Z-axis gripping system 15 is fixedly installed on the top of the floor 1 and on one side of the gripping robot 16, which can guide the gripping robot 16. An electrical board 17 is fixedly installed on the top of the floor 1 near the center of the edge, which can move the raw material after welding.

[0023] Example 2, as Figure 1-4 As shown, support columns 2 are fixedly installed at the bottom of the floor 1 and near the four corners. The bottom of the support columns 2 is fixedly connected to the base frame 3, which can support the bottom of the floor 1.

[0024] Working principle: First, the required processing fixture is laid flat in the full fixture tray on the upper and lower material trays 11 by the operator. The fixture tray with the fixture placed is then embedded below the Z-axis camera system 10 in the processing area. At this time, the track sensing system senses the embedding of the fixture tray and issues a command to start the cylinder motor and track to transport it to the processing area. Then, the cylinder slide rail transports the fixture tray to the processing area. After the processing area sensing system senses it, it issues a processing command to start and control the X-axis guide rail 9, the first Y-axis guide rail 6, the second Y-axis guide rail 7, and the Z-axis camera system 10. At this time, the camera can capture the fixture in the fixture tray for precise positioning. After precise positioning, a command is issued to start the cylinder at the gripping robot 16 to grip and rotate the fixture by a specified degree. The upper camera system 13 scans and positions the fixture with the adsorption head in the docking area. The gripper then transfers the fixture to the laser welding head 12 and transports it to the lower camera via the slide rail. At this time, the upper and lower cameras are aligned to confirm the positioning. After the upper and lower cameras accurately capture and position the product, the track connects the material gripped by the gripper to the product. Then, the gripping robot 16 picks up the fixture and product again and transports them to the fixture rotation mechanism 14. After the fixture is placed, it is scanned by a barcode scanner to bind the product number. At this time, a command can be issued to start the vibratory feeder to rotate 90° to the processing position. At this time, the laser automatically starts preheating. The cylinder that senses the fixture presses down the rotary motor with springs and sensors. The pressing frequency and weight are detected in real time to reduce fixture wear. The rotary motor rotates at a fixed frequency while pressing down. The X and Y axes controlled by the two axes can move the laser welding head 12 to perform precise welding around the ring, completing a vehicle radar welding system. After the welding of the fixture and product is completed, the automatic rotary table of the fixture rotation mechanism 14 can rotate 90° again. After the rotation is completed, the welded product can be transported to the unloading position. The unloading sensor system senses the material and sends a signal. The cylinder starts the gripper to hold the welded product and rotate it to the unloading product conveyor for unloading.

The appropriate models are selected according to actual use. Therefore, the control methods and wiring layouts of the X-axis guide rail 9, Z-axis camera system 10, laser welding head 12, camera system 13, fixture rotation mechanism 14, Z-axis gripping system 15, gripping robot 16, electrical board 17, and cable chain plate 18 will not be explained in detail.
