[0062] Repeat the above operation, and then move another bottom plate 7 with another fixed automobile component 9 to the bottom of the guard plate 6. The moving plate 10 moves up to drive the bottom plate 7 to move up. The bottom plate 7 moves up so that the column 806 on the bottom plate 7 is inserted into the columnar slot of the heightening plate 805 above the bottom plate 7. The movement of the bottom plate 7 will drive the bottom plate 7 above it to move. At this time, the bottom plate 7 moves to connect with the support plate 802 at the bottom, and the bottom plate 7 above it is connected with the upper support plate 802. Repeat the above operation until the bottom plate 7 is connected with the topmost support plate 802. At this time, turn on the welding robot 4, and the bottom plate 7 is connected with the top support plate 802. The automobile parts 9 on the plate 7 are welded. After welding, the base plate 7 and the welded automobile parts 9 on the base plate 7 are taken away by the grabbing robot 5. At the same time, the moving plate 10 moves again to move the fixed automobile parts 9 and their base plate 7 to the guard plate 6, and push the other base plate 7 to move to the top support plate 802 position, which facilitates the welding work of the welding robot 4, shortens the downtime of the welding robot 4, and improves the working efficiency of the welding robot 4. This is the use process of the high-frequency welding equipment for automobile parts.
