Problems solved by technology

For example, if the control system of the moving part of the inspection equipment does not know in time that the moving part hits the object under inspection such as luggage or industrial parts, it cannot make the necessary commands in time to stop the moving part, so the object under inspection may be damaged; sometimes The detection device itself can even be bruised by the object being inspected
[0009] In addition, because the membrane switch is usually very sensitive, for example, a force of 0.5 Newton or even less can make it respond, so a separate membrane pressure sensor may make a misjudgment due to unexpected reasons such as machine vibration when used, thus making False triggering of control systems for moving parts, resulting in unnecessary downtime of the entire system, costing time and money

Embodiment Construction

[0020] One or more specific embodiments of a curved membrane pressure sensor will be described below. In an effort to provide a concise description of these embodiments, all features that are actually implemented may not be described in the specification. It should be realized that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints etc., constraints may vary between implementations. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0021] When introducing elements of various embodiments of the presently disclosed subject matter, the articles "a," "the," and "said...

Abstract

The invention discloses a curved-surface film pressure sensor and a manufacturing method thereof, wherein the curved-surface film pressure sensor is used for a moving part and comprises an elastic curved-surface shell and a splitting type mesh film switch formed on the curved-surface shell, the side, opposite to the curved-surface shell, of the splitting type mesh film switch is coupled to a cutting board shell of the moving part, and the splitting type mesh film switch is used for sensing whether pressure is applied to the curved-surface shell. The curved-surface film pressure sensor can meet appearance requirements of the moving part and sense touch effectively to prevent a detected object from being damaged, and can also effectively resist fire and water.

Description

technical field [0001] The present invention generally relates to the field of thin-film pressure sensors, and more particularly, the invention relates to a curved-surface thin-film pressure sensor for moving parts and a manufacturing method thereof. Background technique [0002] In recent years, due to the advantages of good stability, small size and high reliability, thin-film pressure sensors have been widely used in industry. Thin film pressure sensor is generally considered as an ultra-thin multi-layer electromechanical device, in which electrodes and connecting wires are arranged in an orderly manner on the sensing element and its lamination structure, and a solid structure is made of suitable polymer film and epoxy resin materials. ultra-thin package structure. When the membrane pressure sensor is subjected to a sudden contact pressure or a continuously changing pressure, tension, or velocity field, an electrical signal will be generated for outputting corresponding ...
