Image measuring instrument about the light source application of 2.5-dimensional measuring instrument
The light source application of the image measuring instrument about the 2.5-dimensional measuring instrument. 2.5-dimensional measuring instrument is also called auxiliary measuring instrument, or image measuring instrument and video measuring instrument. It is used to measure the size of products and molds. Measuring elements include position, concentricity, straightness, profile, roundness and dimensions related to the datum. It is used to measure the dimensions of two-dimensional planes and is widely used in various precision industries. Mainly used for calipers, angle rulers are difficult or impossible to measure, but they play an important role in the size and angle of parts in assembly, such as silica gel, circuit board creepage distance, electrical clearance, control panel light holes, and plastic parts. Specific size, etc. can also be used to take pictures of certain parts to analyze the causes of defects. Since the image measuring instrument is an image obtained by irradiating the part with surface light or contour light, it is necessary to acquire points for measuring the part. Not all parts are measured by the secondary element measuring instrument, which is a more accurate method. The better method is more effective, and the method of measuring the size of the part is more accurate.
It is a high-precision measuring instrument, and it is not easy to apply. First, learn from all aspects of the body, and then understand the composition and purpose of surgery. Now, let's start with the light source of the image measuring instrument. In order to give you a more intuitive understanding of the light source of the image measuring instrument, the light source of the projector is located under the slide film, and the light passes through the slide film to finally form an image. The light source of the 2.5-dimensional measuring instrument is located on the upper projection sheet, and then the light is reflected by the reflection of the projection sheet. Since the light passes through the projection sheet twice, the light density is doubled, and the image projected by the 2.5-dimensional measuring instrument has a large contrast and particularly saturated colors. The light source of the 2.5-dimensional measuring instrument is also located on the top of the projection sheet, and the light is reflected by the metal film on the projection sheet. The back of the wrinkled lens is then transmitted through the projection sheet to form an image. During the imaging process, there is both reflection and transmission, so it is called a reflection-transmission combined projector. The light source of the image measuring instrument plays an important role in the image measuring instrument system. It can even be said that it determines the function of the image measuring instrument.
Therefore, it is necessary to understand the light source of the image measuring instrument, both for the operator and for the developer.
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.
