Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. refer to figure 1 , figure 2 , image 3 , The automatic method for measuring the weight and thickness of a large honeycomb sheet disclosed in the present invention includes an automatic thickness measurement and weighing instrument composed of a weighing unit 1, a thickness measuring unit 2, a material receiving platform 3, and a control system 4.

[0028] The weighing unit 1 is used for weighing and measuring the sliced ​​honeycomb sheet, and positioning and conveying the weighed sheet. The weighing unit 1 is composed of a platform 6, a load cell 7, a honeycomb sheet conveying device 5, etc. Composition; the load cell is installed under the table, which is four symmetrical installations. When the honeycomb sheet is placed anywhere on the table, the signal measured by the load cell is fed back to the weighing control system, and the system displays the...

Abstract

The invention belongs to the technical field of composite materials, relates to a weight and thickness measuring method of a honeycomb sheet with large area and low stiffness, and particularly relates to an automatic honeycomb sheet weight and thickness measuring method which has the advantages of easy operation, simple structure and convenient use. A device manufactured through the method of comprises a weight measuring unit, a thickness measuring unit, a material receiving platform and a control system. Thickness measuring, weighing measuring and density calculating of the honeycomb sheet can be realized. Whether the thickness and the density of a sliced honeycomb block are qualified can be detected, and the precision degree is detected. According to the invention, the method is used for precise weight and thickness measuring of the honeycomb sheet, and meets a high quality honeycomb evaluation requirement; the device manufactured through the method realizes full process automation of weight and thickness measuring; the detection efficiency is greatly improved; an inspection requirement of mass production is met; and the method has the advantages of high measuring precision, good repeatability, safe honeycomb sheet, high efficiency and simple operation.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a method for measuring the thickness and weight of a large-area, low-rigidity honeycomb sheet, in particular to a method for automatically measuring the weight and thickness of a honeycomb sheet. Background technique [0002] The density and thickness of high-performance honeycomb sheets have precise requirements, and the method of weight measurement and thickness measurement is used to directly obtain the thickness size and calculate the density value. Generally, the thickness measurement method of honeycomb sheet is to use a micrometer to complete the measurement manually, and the weighing of the honeycomb sheet is measured on an ordinary platform scale. Therefore, it is very urgent and necessary to propose a new evaluation method. For this reason, the present invention proposes a new evaluation method. Contents of the invention [0003] The purpose of the present...
