Problems solved by technology

In the later stage of the production of strain gauge products, it is necessary to separate the individual strain gauge products from the whole plate, and test the individual strain gauge products, and finally sort them according to the test results. The current existing method is to manually use scissors along the product The outer frame trims a single product, and manually detects and sorts a single product. This manual sorting method not only has low production efficiency, high labor intensity, high production cost, and is prone to errors, which is not conducive to the stability of product quality. sex control

Abstract

The invention discloses an automatic sorting method of large-array resistance strain gages. A device adopted by the method comprises a rack, a positioning and fixing mechanism, an adsorption sorting mechanism, a positioning sorting mechanism, a computer, a data acquisition card and an output amplifying board. The method comprises the following steps of (1) inputting a sorting instruction on the computer after diaphragms, which are placed on a vacuum adsorption table, of the large-array resistance strain gages are detected; (2) carrying out sorting and locating; (3) carrying out sorting and adsorbing; (4) sorting class A resistance strain gages; (5) sorting class B resistance strain gages; (6) sorting class C resistance strain gages; (7) sorting class D resistance strain gages; (8) sorting class E resistance strain gages; (9) carrying out sorting and locating for the next time. The automatic sorting method has the advantages of novel and reasonable design, low implementation cost, high working reliability, high practicability and high popularization and application value, the production efficiency can be improved, and the labor intensity of workers and the production cost of products are reduced.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent application with the application date of December 31, 2015, the application number of 201511030252.X, and the invention-creation title of "A Large Array Resistive Strain Gauge Automatic Sorting Device and Method". technical field [0002] The invention belongs to the technical field of resistive strain gauge production, and in particular relates to an automatic sorting method for large array resistive strain gauges.
