Description

Technical Field

[0001] The present invention belongs to the technical field of automated production equipment, and particularly relates to a laser spot welder. Background Art

[0002] During the assembly of the glue core and the iron shell, a laser spot welding device is used to perform spot welding through laser, so as to achieve assembly welding. At the same time, the laser welding has a fast response speed and accurate positioning, making the spot welding more accurate and not easily damaging the glue core.

[0003] At present, the spot welders on the market are semi-automatic when welding and assembling between the glue core and the outer shell.

[0028] The working principle and usage process of the present invention: When assembling the rubber cores of the present invention, they are placed on the feeding seat 8 through the feeding vibrating disk, and the position is identified by the position sensor. The telescopic cylinder drives the sliding plate in the feeding seat 8 to slide, so as to adjust the position of the rubber cores. At this time, the material taking mechanism 25 performs vacuum adsorption material taking, and sequentially places them on the rotating mechanism 2 and the welding support 9 for flip spot welding. The rubber cores after the first spot welding are placed at the first rotating mechanism 2 and rotated 180 degrees to realize spot welding at the replacement surface, ensuring that both sides can be welded. Then, the rubber cores after double-sided welding are placed in another rotating mechanism 2 and rotated 90 degrees to adjust their placement angle. They are placed into the distance adjusting mechanism through the material taking mechanism 25. Through the upward adjustment of the adjusting component in the distance adjusting mechanism, the two rubber cores are adjusted to be at the same horizontal position. The material taking mechanism 25 takes the materials and places them on the tray 18 in the moving frame 17 of the upper cover mechanism 3. At this time, the upper cover vibrating disk feeds the lids, and the lids are conveyed into the lid feeding bin 16. At this time, the pushing cylinder drives the tray 18 to slide, so that the rubber cores are at the upper cover port position. At the same time, the first pneumatic telescopic rod 15 pushes the push cover plate 13, and the push cover plate 13 pushes the lid to slide in the lid feeding bin 16, so as to be sleeved on the rubber cores to realize upper covering. After the upper covering is completed, they fall into the material receiving mechanism 4 through the blanking plate 23. Through the mutual cooperation of the second pneumatic telescopic rod and the third pneumatic telescopic rod 24, the finished products on the material sliding frame 21 are pushed into the material receiving pipe 6 to realize pipe loading. The whole process is fully automated, ensuring that the processing spot welding is more accurate and reliable, and time-saving and labor-saving.
