Abstract

The invention discloses a 3D printing one-off two-stage pressure sensor, which comprises a first part and a second part, wherein the first part comprises a first thin plate layer and a vertical stressed boss located in the center; the second part has a hollow rectangular box body structure; the box body internally comprises a first boss and a second boss extending horizontally, a crossbeam, and an inverted cone boss; the first boss and the second boss are distributed at two opposite sides of the box body in an axial symmetry mode; the crossbeam is located right below the first boss and the second boss and crosses over two opposite sides of the box body, and the inverted cone boss is located in the center of the crossbeam; and the first thin plate layer of the first part is located on the upper surface of the two horizontally-extending bosses of the second part and is contacted with the bosses. two-stage pressure detection can be realized, and the limitation that the original similar sensor can only detect one-stage pressure can be overcome; 3D printing integrated forming can be adopted, and quick manufacturing is realized; no electronic device is used, and the price can be reduced to a large degree; and the portability is strong.

Description

technical field

[0001] The invention belongs to the technical field of intelligent robots, and in particular relates to a 3D printing disposable two-stage pressure sensor. Background technique

[0002] With the rising labor costs in the manufacturing industry and the shortage of skilled workers, more and more robots and automation equipment have been introduced into the production and processing fields of various industries, such as welding robots, feeding robots and polishing robots. With the rapid development of this trend, a human-machine fusion robotics technology has emerged, which combines the intelligence and agility of humans with the strength, repeatability and durability of industrial robots, combining the advantages of both groups. fusion. Since most robots are powerful moving machines, the safety and security of people working around these robots becomes a priority. Traditional contact sensors represented by pressure sensors measure force accurately based on th...

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1-Figure 3 As shown, the 3D printed disposable two-stage pressure sensor of the embodiment of the present invention mainly includes: a first part 1 and a second part.

[0024] The present invention uses a micro press to apply pressure to the stressed boss (12) of the first part (1). As the pressure increases, the first thin plate (11) of the first part (1) is deformed, and the first thin plate concave part 111 and the lower surface of the second sheet recess 112 are gradua...
