Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The invention provides a hydrogen fuel bipolar plate detection method, comprising the following steps:

[0025] S1: Start the 3D camera, move the 3D camera to the position where the sample needs to be measured, use the clamp clamping device to press the vicinity of the measurement position, and perform sampling measurement of thickness, length, width, etc.

[0026] S2: After the 3D camera takes pictures, move the sample to the starting position of the lin...

Abstract

The invention discloses a hydrogen fuel bipolar plate detection method, which comprises the following steps: firstly, starting a 3D camera, moving the 3D camera to a position where a sample needs to be measured, pressing the vicinity of the measurement position by using a clamp clamping device, carrying out sampling inspection measurement on thickness, length, width and the like, moving the sample to a shooting starting position of a line scanning camera, and carrying out shooting treatment on the whole product. The method comprises the following steps: detecting front defects, measuring the size, moving to the position of a back camera after a front line scanning camera finishes photographing, overturning a product, photographing the back of the product, detecting the defects of the back, summarizing data in an industrial personal computer internal unit, and analyzing and processing the carding. According to the hydrogen fuel bipolar plate detection method, the used deep learning algorithm can solve the problems of positioning, detection, classification and the like of complex defects, the hydrogen fuel bipolar plate detection method is suitable for complex application scenes, meanwhile, the hydrogen fuel bipolar plate detection method has a powerful self-learning function, and the defect detection rate can be continuously increased along with continuous operation of software.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a hydrogen fuel bipolar plate detection method. Background technique [0002] The bipolar plate, also known as the current collector plate, is one of the important components of the fuel cell. The bipolar plate has the following functions and properties: separates the fuel and the oxidant, prevents the gas from permeating; collects and conducts current, with high electrical conductivity; The flow channel can evenly distribute the gas to the reaction layer of the electrode for electrode reaction; it can discharge heat and keep the battery temperature field uniform; corrosion resistance; shock and vibration resistance; thin thickness; light weight; at the same time, low cost, easy machining, suitable for mass production, etc. [0003] Based on the role of the bipolar plate, its characteristics must have both good electrical and thermal conductivity, extremely low gas p...
