Vacuum cup and production process thereof

Abstract

The invention discloses a vacuum cup and a production process thereof. The production process comprises the following steps: 1) assembling and forming an inner pipe and an outer pipe; 2) vacuumizing an interlayer between the inner pipe and the outer pipe of the cup body; 3) performing laser treatment on the surface of the cup body to meet the surface requirement of a baking finish process; (4) baking finish treatment is conducted on the surface of the cup body; 5) performing quality inspection: if surface defective products appear in quality inspection, returning to the step 3) to carry out laser treatment again. According to the scheme, the original complex electrolysis, grinding, paint stripping and rust dispensing procedures influencing the health of operators are abandoned, the advantages of the laser treatment process are fully utilized to meet the surface requirements of the paint baking procedure, and the good product yield can be obtained. Compared with the prior art, the production line investment is effectively controlled by optimizing the existing production process, and the body health of operators can be ensured.

Description

technical field [0001] The invention relates to the technical field of thermos cup production, in particular to a thermos cup and a production process thereof. Background technique [0002] With the increasing demands of people's daily life, the thermos cup can effectively reduce the heat dissipation and achieve the purpose of heat preservation due to its ability to reduce the heat exchange rate between the hot water in the cup and the external environment. Among them, the thermos cup made of metal material has been welcomed by consumers because of its high structural strength and good anti-fall performance. [0003] Usually, this kind of thermos cup made of metal material includes two parts, an outer shell and an inner container, and its production process includes the processes of inner and outer tube assembly, vacuum, electrolysis, grinding, and baking varnish. In the quality inspection process, when there are particles, scratches and other defective paint surface, the e...

AI Technical Summary

Problems solved by technology

In the quality inspection process, when there are particles, scratches and other defective paint surface, the existing process needs to remove the paint of the product first, rust off the cup body, and then put it into the grinding and baking process again, which greatly wastes manpower and material resources. , financial resources; on the other hand, the existing production process is cumbersome, and there are relatively many types of machines involved, requiring professional maintenance of multiple types of machines, high personnel costs, and high machine maintenance and purchase costs

[0004] In particular, strong acid paint strippers are required for the process of removing paint and spot rust, which will corrode the skin of the workers and endanger the health of the workers if they are not careful; in addition, the dust pollution in the grinding process is serious, and it is harmful to the health of the workers Serious threats, especially serious damage to the lung health of workers, requiring a large amount of financial resources to conduct physical health checks for workers every year
