Technical application of laser welding machine and marking machine in a thermos cup

The most basic requirement for vacuum flasks is sealing. The stainless steel mug is made of double stainless steel inside and outside. The laser welding machine uses welding technology to join the lining and the outer shell together and then uses vacuum technology to separate the air between the lining and the outer shell. Pull it out to achieve the effect of vacuum heat insulation. Only in this way can we ensure a good experience! Generally speaking, the thinner the cup material, the lower the welding ability. However, the welding port is not firm, and the cup body is easily broken and deformed, affecting the service life. A metal film is coated on the inner layer of the lining, and a certain thickness of copper plating is coated so that the welding interface is not easily damaged by the metal material used for splicing! In this way, the welded joint is dense and high-strength, and absolute tightness is achieved.

In general, the thinner the cup material, the longer the holding time. However, the cup body is easily damaged and deformed, affecting the service life. Measures such as metal film and copper plating on the inner layer of the inner cup of the vacuum cup can also improve the degree of insulation; the large-capacity, small-diameter vacuum cup has a longer holding time, and on the contrary, its capacity is smaller. Large-diameter vacuum insulated cups have a shorter holding time. Two pieces of stainless steel 316 304 430 201 direct breakdown welding and butt welding, they are stacked together, the thickness is 1mm, butt welding can be joined together, and directly welded together with a thickness of less than 5mm, and the thickness of the seal welding is 0.3mm——The welding range is 5mm, the above welding tension can reach 2 tons, and the sealing pressure test can reach 20kg;

Characteristics of vacuum bottle laser welding machine:

    1. Process feedback data in real-time to achieve ideal welding conditions;

    2. The combined design of the galvanometer scanning head realizes spot welding and seam welding within the processing range.

    3. The output of the laser can achieve divergence at the same time, time divergence and a maximum of 4 divergences;

    4. Gradually enter and exit function to complete the overlap between the beginning and end of seam welding;

    5. Input and output (signal) settings make automation easier;

    6. The optional robot system can be used to realize special welding, precise positioning, and real-time monitoring of welding.

With the increasing maturity of laser technology and the advancement of laser welding technology, a major breakthrough has been made in the welding of stainless steel vacuum bottles. From traditional argon arc welding to laser welding, due to the small surface deformation of the product and the dense solder joints, laser welding is favored by customers without requiring more post-processing. OPTIC is one of the first batches of laser welding machine equipment manufacturers. It has more than ten years of R&D and production experience and is a leader in technology and integration. Since the establishment of the company, it has been paying attention to the development of laser technology and the development needs of customers and is committed to providing complete material processing solutions for each enterprise.
