[0022] The technical solution of the utility model is further described below by way of embodiments:

[0023] The utility model provides a high-speed welding device for a shielding cover, such as Figure 1 As shown, the welding equipment includes: a turntable 1, a cover feeding mechanism 2, two cover manipulators 3, two flexible vibration disks 4, two welding rib manipulators 5, a welding mechanism 6, a clamping mechanism 7, a material receiving box 8, two front and back detection mechanisms 91, two flying detection mechanisms 92, a welding rib position detection mechanism 93 and a finished product detection mechanism 94. The turntable 1 has four indexing positions, which are a cover feeding position, a welding rib feeding position, a welding position and a unloading position. The cover feeding mechanism 2 corresponds to the cover feeding position of the turntable 1, the two flexible vibration disks 4 correspond to the welding rib feeding position of the turntable 1, the welding mechanism 6 and the clamping mechanism 7 correspond to the welding position of the turntable 1, the material receiving box 8 corresponds to the unloading position of the turntable 1, and a The picking and placing range of one cover body manipulator 3 covers the cover body feeding mechanism 2 and the cover body feeding position of the turntable 1, the picking and placing range of another cover body manipulator 3 covers the material receiving box 8 and the unloading position of the turntable 1, the picking and placing range of one weld rib manipulator 5 covers a flexible vibration disk 4, a flying pat detection mechanism 92 and the weld rib feeding position of the turntable 1, the picking and placing range of another weld rib manipulator 5 covers another flexible vibration disk 4, another flying pat detection mechanism 92 and the weld rib feeding position of the turntable 1, the two front and back side detection mechanisms 91 are respectively located directly above the two flexible vibration disks 4, the weld rib position detection mechanism 93 is located directly above the weld rib feeding position of the turntable 1, and the finished product detection mechanism 94 is located directly above the unloading position of the turntable 1.

If there is no weld rib facing up (that is, only the weld rib facing up), the flexible vibration disk 4 vibrates to turn the weld rib over, and the weld rib manipulator 5 takes out the weld rib facing up from the flexible vibration disk 4.

If it is a good product, it is placed on the cover body at the weld rib feeding position; then, the weld rib position detection mechanism 93 shoots from bottom to top to detect whether the position of the weld rib is normal. If it is normal, the turntable 1 transfers the cover body to the welding position by rotating, the clamping mechanism 7 presses the cover body and the weld rib, and the welding mechanism 6 welds them; finally, the turntable 1 transfers the finished product of the cover body to the unloading position by rotating, and the finished product detection mechanism 94 detects whether there is any abnormality in the welding.
