The processing and realization of the loading and unloading system of fully automatic welding equipment is inseparable from various changes and updates. For example, the four major hardware sensors, including on-board cameras, millimeter-wave radars, laser radars, and ultrasonic radars, are the eyes of self-driving cars and provide key information for environmental perception.

[0003] Radar welding loading and unloading products have been increasingly widely used in industrial manufacturing automation production lines. In order to meet the requirements of semi-automation to full automation of production lines, it is necessary to produce advanced radar welding loading and unloading fully automated equipment that reduces labor, has high speed and high efficiency. To this end, it is necessary to improve the portable structure of manual operation of the equipment to make it compact and mass-produced. The full automation of the radar welding loading and unloading system is an epochal turning point for the structural update of many welding product equipment, and plays an important role in the update of the radar welding loading and unloading structure from semi-automatic to fully automated.

[0024] Working principle: First, manually lay the required processing jigs on the full jig trays on the upper and lower material trays 11, and embed the jig tray with the jigs placed under the Z-axis camera system 10 in the processing area. At this time, the track sensing system senses the embedding of the jig tray and issues a command to start the cylinder motor track to transport it to the processing area. At this time, the cylinder slide rail transports the jig tray to the processing area. The processing area sensing system senses and 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 jig in the jig tray for precise positioning. After precise positioning, a command is issued to start the cylinder at the grasping manipulator 16 to clamp and rotate the jig to a specified degree. The upper camera system 13 scans and locates the adsorption head in the docking area, and the clamp transports the jig handover laser welding head 12 to the lower camera through the slide rail. At this time, the upper and lower cameras are matched to determine the positioning. After the upper and lower cameras accurately capture and locate the material on the track and connect the material clamped on the clamp with the product, the gripping robot 16 will pick up the fixture and the product again and transport them to the fixture rotating mechanism 14. After the conveyed and placed fixture is scanned and bound to the product number by the barcode scanner, a command can be issued to start the vibration plate to rotate 90° to the processing position. At this time, the laser automatically starts to preheat, and the jig cylinder senses that the rotating motor with a spring and a sensor will be pressed down. The pressing frequency and weight are detected in real time to reduce the loss of the jig. The rotating motor rotates at a fixed frequency while pressing down, and the X and Y axis movable laser welding head 12 controlled by two axes performs precise welding of the circle, completing a vehicle-mounted radar welding system. After the welding of the fixture and the product is completed, the jig rotating mechanism 14 can automatically rotate the rotating disk again by 90°. When the rotation is completed, the welded product can be transported to the unloading position. The unloading induction system senses the material and sends a signal, and the cylinder starts the gripper to clamp the welded product and rotate it to the unloading product conveying plate for unloading and conveying.
