Problems solved by technology

Taking the gold wire bonding process as an example, in the prior art, one is to manually complete the gold wire bonding, and the bonding quality is observed manually after the bonding is completed, which is inefficient; the other is that the bonding machine automatically completes the bonding and roughly Judgment (connection or not), and then assist manual observation of the bonding quality, the bonding machine only roughly judges during the bonding process, but cannot detect the neck sagging after the bonding is completed, that is, it needs to be manually reassessed after the bonding is completed. inspection, low efficiency

Abstract

The invention discloses a fault diagnosis method and device for a pressure sensor, equipment and a storage medium. The fault diagnosis method for the pressure sensor comprises the following steps: acquiring a first image in a first direction in real time through a micro image device, wherein the micro image device is arranged in the pressure sensor; according to the first image, determining a contour image of a to-be-evaluated object; performing region division on the contour image according to a preset region division rule; and judging whether the to-be-evaluated object has defects or not according to the contour image after region division.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a fault diagnosis method, device, equipment and storage medium for pressure sensors. Background technique [0002] The processing of traditional pressure sensors usually includes cleaning, patching, gold wire bonding and other processes. Taking the gold wire bonding process as an example, in the prior art, one is to manually complete the gold wire bonding, and the bonding quality is observed manually after the bonding is completed, which is inefficient; the other is that the bonding machine automatically completes the bonding and roughly Judgment (connection or not), and then assist manual observation of the bonding quality, the bonding machine only roughly judges during the bonding process, but cannot detect the neck sagging after the bonding is completed, that is, it needs to be manually reassessed after the bonding is completed. Inspection, low efficiency. [0003] ...
