Description

Technical Field

[0001] The present invention relates to an automatic expansion device, in particular to an expansion device for a balloon. Background Art

[0002] At present, balloons are widely used as carriers for placing sensors in many fields, such as medical surgery, high-precision instrument testing and unmanned exploration of special environments. Therefore, the accuracy of balloons as extension devices of exploration instruments is becoming more and more precise. The sensor is placed inside the balloon and connected to the detection equipment outside. The position of the sensor inside the balloon needs to be accurately installed. Since the balloon is used differently in different environments, its structural materials are also different. However, the balloon itself is a spherical structure, and opening and closing and positioning are difficult to complete. Therefore, in large-scale production, it is impossible to expand it quickly and expand it into place at the same time. In traditional processes, manual operation is required to achieve the positioning and expansion of the balloon so that subsequent operations can be carried out. Rapid automated processing cannot be achieved because multiple grippers are required to operate simultaneously, and the moving directions of each gripper are opposite to each other and cannot be unified, making it difficult to achieve automatic operation.
