What is the working principle of the two-dimensional imager? With the increasing demand for measuring instruments, as long as the accuracy and size requirements are involved, the accuracy of the product and the processing of the product must be verified by the size measurement device. In this process, quality inspectors often encounter two-dimensional imagers. The two-dimensional imager, also known as an image measuring instrument, mainly measures the two-dimensional dimensions of the length and width of precision parts, and can also be used to make CAD drawings of both-product dimensions in some special fields. The marble base and column used by the secondary measuring instrument greatly improve the stability of the product and is less affected by temperature. Because it is a two-dimensional size measurement, the product to be tested is relatively small. The two-dimensional imager uses its own hardware CCD, eyepieces, objective lens data cable, and video capture card to transmit the captured image to the computer's data capture card through the data cable, and then image the image through software. On the computer monitor, the user uses the mouse to make quick measurements on the computer.
The above process is basically completed in tens of thousands of seconds, so it can be regarded as a real-time detection device, or the narrow point can be called a dynamic measurement device. If the configuration of the secondary image measuring instrument is satisfactory, the device will never produce image lag. Due to the size of the workpiece, the table can choose different strokes. The brightness of the two-dimensional imager is adjustable, and the most suitable light source brightness can be selected under various light conditions. With the increasing demand for measuring instruments, as long as the accuracy and size requirements are involved, the accuracy of the product and the processing of the product must be verified by the size measurement device. In this process, quality inspection personnel often encounter two-dimensional imagers.
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.
