Combined blind measurement device for geometric parameters of polymer injection molding product

Abstract

The invention discloses a combined blind measurement device for geometric parameters of a polymer injection molding product, which mainly takes a single chip microcomputer, a dial indicator and a PC as a main body, and integrates a Bluetooth transmission module, an RFID module and an LCD. In the process of measuring the depth of each hole in a product to detect the geometric uniformity parameter of the product, the RFID module identifies the position of each hole in the product, and the Bluetooth transmission module uploads the depth data, measured by the dial indicator, of the holes in the product to the PC terminal for storage. Finally whether the thickness of each part of the product is uniform or not is judged according to data recorded by the PC terminal. In order to facilitate the observation of the data by the staff, the measured data is displayed through an LCD screen connected to the single-chip microcomputer. According to the invention, blind measurement of data of holes in a product and separation of a field measurement end and a data management end can be realized, and the measurement efficiency and effective management of the data of the holes in the product can be effectively improved.

Description

technical field [0001] The invention relates to the field of digital detection devices, in particular to a combined blind detection device for geometric parameters of polymer injection molding products Background technique [0002] When using the polymer injection molding process for production operations, it is necessary to effectively measure the geometric parameter data of the cast product, especially whether the thickness of each part of the cast product is uniform to ensure the quality of the product. An effective method is to fix the formed product on a standard testing mold, and measure the thickness of different parts of the product by measuring the corresponding hole position, so as to achieve the purpose of testing the geometric uniformity parameters of the product. Since measuring tools such as dial indicators do not have the function of positioning and identifying holes, the traditional detection method is that the staff use measuring tools such as dial indicator...

AI Technical Summary

Problems solved by technology

During the measurement process, if the hole data records are wrong or several holes to be measured are omitted, it will cause data measurement errors, and the quality of the product cannot be judged, and the measurement needs to be re-measured, which requires a lot of on-site measurement personnel. Time and energy greatly delay the progress of product inspection, and cannot meet the work requirements of the separation of the on-site data measurement end and the data management end
