Does the manual two-dimensional measuring instrument have application disadvantages? Publish time: 2019-12-27 Source: https://www.microaccuracy.com/ The two-dimensional image measuring instrument is a device that focuses on precise measurement of two-dimensional planes. It is divided into active and manual measuring instruments. Manual measuring instruments are a kind of Equipment that is being phased out, but there are still some companies choosing because of the price advantage, so does the manual two-dimensional measuring instrument have application disadvantages? Manual two-dimensional measuring instruments are currently being gradually banned by automatic image measuring instruments. Due to their manual operation and uncontrollable errors, it is difficult to meet the growing measurement needs of the manufacturing industry. Compared with automatic image measuring instruments, they have the following application disadvantages : The measurement results are highly random and poor in accuracy: In addition to the accuracy limitations of the manual measuring instrument itself, the measurement results are largely random, mainly because the manual two-dimensional measuring instrument requires a large amount of human participation in the measurement process, and there is no computer assistance and intelligence cannot be realized. Instead of extracting primitives and manual focusing, relying on human eye judgment to extract primitives and manual focusing, and relying on manual judgment to extract manually: each person extracts manually according to their own human eye judgment, which causes the measurement results to vary from person to person. Large errors; even when the same person performs multiple measurements, large-scale measurement errors often occur. Low measurement efficiency and huge hidden cost: In addition to measurement accuracy errors, low measurement efficiency is also a major problem with manual measuring instruments. Many people choose manual measuring instruments because of their low price and low cost, while automatic image measuring instruments are expensive. , But in fact, the hidden cost of the manual two-dimensional measuring instrument is more comprehensively calculated. The measurement efficiency of the automatic image measuring instrument is 10-50 times that of the manual instrument, and the measurement efficiency is higher in industries such as PCB and LCD. When measuring the same workpiece, if it takes 1 unit time for automatic measurement and 10-50 unit time for manual measurement, manual imager will consume 9-49 times more unit time. This efficiency is in the case of mass inspection. Time will bring more cost losses to the enterprise. The automatic image measuring instrument performs rigorous large-data calculations on primitive edge extraction, image scanning, data analysis, etc. through powerful computer algorithms. It can provide users with more automated and standardized operation steps and methods, avoiding manual operations. The human operation error of the image measuring instrument ensures accurate measurement accuracy, and the non-contact measurement method brings high efficiency measurement efficiency. The manual two-dimensional measuring instrument is currently difficult to meet the measurement needs of modern manufacturing. The automatic image measuring instrument has better performance and advantages in use, and will be a better choice for industrial production. Miaoji Technology has focused on the Ru0026D and production of precision measuring equipment for many years. Currently, it can provide a variety of high-quality automatic two-dimensional measuring instruments and one-button measuring instruments!
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
