Automatic continuous welding system for capsule and welding method of automatic continuous welding system

Abstract

The invention provides an automatic continuous welding system for a capsule and a welding method of the automatic continuous welding system. The automatic continuous welding system for the capsule involves a capsule flap conveying mechanism, an automatic aligning mechanism, a welding mechanical arm mechanism and a digital display control system which are sequentially arranged and electrically connected; the capsule flap conveying mechanism is used for conveying capsule flaps needing to be welded to the automatic aligning mechanism; the automatic aligning mechanism is used for aligning and positioning the welded positions of the capsule flaps; and the welding mechanical arm mechanism is used for heating and cooling the welded positions of the capsule flaps. Compared with the prior art, thesystem and the method have the beneficial effects that the capsule flap conveying mechanism is introduced to replace manual moving so that the large capsule flaps can be stably fed into a welding machine;the automatic aligning device and a welding mechanical arm are synchronized, so that it is ensured that capsule materials are stably and orderly welded; and the digital display monitoring system is developed, so that the welding quality dynamic state is automatically adjusted and controlled, the automation and programming of capsule welding production are achieved, and the capsule production speed and production quality are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of aerostat capsule processing, in particular to an automatic continuous welding system and a welding method for a capsule. Background technique [0002] An aerostat is a flexible aircraft that mainly relies on buoyant gas to achieve lift-off and stay in the air. The manufacturing process of the capsule body of the aerostat is to cut the reinforced composite fabric or film fabric into capsule flaps according to the design, and carry out two-to-two alignment connection and thermocompression bonding to form. This thermocompression bonding molding process is Welding of the capsule flap of the capsule body; the edge of the capsule flap is called straight line welding, and the edge of the capsule flap is called curved welding; the heat-sealing area where the two capsule flaps are connected to each other is called the weld. At present, the manufacturing process of aerostat capsules at home and abroad has the foll...

AI Technical Summary

Problems solved by technology

At present, the manufacturing process of aerostat capsules at home and abroad has the following deficiencies, which are reflected in: first, high-frequency and hot-melt welding are commonly used as intermittent operations, and the operation speed for curve welding is low, and large-scale capsule flaps are welded during welding. It is inconvenient to move and feed materials, time-consuming and labor-intensive

Second, although the hot air welding machine is a continuous welding operation, for ultra-thin thylakoid welding due to the use of hot air heat transfer, it is easy to cause problems such as wrinkles and out-of-control weld width. difficult to operate

Thirdly, although there are belt-type rapid edge-banding welding machines on the market, because the heating distance is too long, it is mostly used for straight-line welding and cannot meet the quality requirements of curve welding, so its application in the aerostat capsule processing industry is quite limited.

Fourth, the improved long-table continuous hot-melt welding equipment, although it adopts program control to automatically replace the hot and cold plate molds to achieve a relatively fast welding speed, is still intermittent in nature, especially for the capsule flap curve welding. Rigid and time-consuming, it fails to fundamentally solve the demand for continuous and rapid curve welding technology for multi-model capsular valves

[0003] To sum up, in the field of aerostat capsule welding processing technology, there is still no system and device to solve the problem of "requirements for universal continuous and rapid curve welding technology for multi-type capsule valves"
