Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The core idea of ​​the present invention is: when measuring the diameter of the indentation, the indentation is photographed by a CCD-based optical information conversion device, the optical signal is converted into an electrical signal, and then converted into a digital signal by an image acquisition card and transmitted to the computer, and then The software processes and calculates the collected images and outputs the results.

[0020] see figure 1 The embodiment of the present invention is provided with a light source 1, an optical information conversion device 2, a CCD camera 3, an image acquisition card 4, an I / O card 5, a sample stage 6, a sample stage control circuit 7, a computer 8, a printer 9, a display 10 and Keyboard A. The light source 1 is placed on the top of the system hardware, and the light emitted by the light source 1 is di...

Abstract

The invention discloses an automatic measuring system for the heat resistance of a thermoplastic material, relates to a thermoplastic material and provides an automatic measuring system for the heat resistance of a thermoplastic material, which has high measuring accuracy and high automatic degree. The automatic measuring system is provided with a light source, an optical information conversion device, a CCD (Charge Coupled Device) camera, an image acquisition card, a sample platform, input equipment, a computer and output equipment, wherein light rays emitted by the light source are directly radiated on an impression sample arranged on the sample platform; reflected light rays of the impression sample are focused on the CCD camera through the optical information conversion device; the digital signal output end of the CCD camera is connected with the image acquisition card; the image acquisition card is connected with the computer; and the input equipment and the output equipment are connected with input and output ports of the computer respectively. The automatic measuring system has the advantages of accuracy as high as +/- 10 mum, objective measuring result, high automatic degree and time and labor saving.

Description

technical field [0001] The invention relates to a thermoplastic material, in particular to a ball pressure test indentation size measurement system used for assessing the heat-resistant properties of thermoplastic materials in electrical safety standards. Background technique [0002] Heat resistance testing is one of the most routine safety testing items for electrical and electronic products. A common method to assess the heat resistance of thermoplastic materials is the ball pressure test. The accuracy of the test results directly affects the qualification of the product. The standard IEC60695-10-2:2003 requires that if the maximum dimension d of the indentation does not exceed 2.0mm, it means that the heat resistance index of the product is qualified. However, the standard does not clearly give a simple and specific operation method on how to determine the indentation diameter. Although it is mentioned in the literature that projection, cutting and other methods can be ...
