What is the structure of the probe connector?
The quick-change fixture can quickly replace the fixture parts of the end fixture (EOAT) of the manipulator needed to remove the product when the mold of the forming machine is switched, and can integrate the sensing parts at the end of the fixture and the signal of the gas path of each part. So, what is the probe connector structure?
What is the structure of the probe connector?
1, electronic optical system:
(1) The system provides an electron beam with a high enough incident energy, a large enough beam current and a small enough beam diameter on the surface of the sample as an X-ray excitation source for electron probe analysis. Therefore, the structure of tungsten wire thermal emission electron gun and 2-3 condensing lenses is generally used. To increase the X-ray signal strength, the electron probe uses a higher incident electron beam current (in the 10-9-10-7A range) than a scanning electron microscope. The commonly used acceleration voltage is 10-30 KV, and the beam spot diameter is about 0.5 m.
(2) The difference between the electron probe and the scanning electron microscope in the tube port part is that it is made of an optical microscope. Its function is to select and determine the analysis point. First, a material that emits fluorescence (such as ZrO2) is placed under electron beam bombardment, so that the position of the electron beam bombardment point can be observed, and it is adjusted to the intersection of the optical microscope eyepiece by the sample moving device, so as to ensure that the electron beam accurately hits the analysis point, and ensure that the analysis point is in the correct position of the X-ray spectrometer. Most optical microscopes used in electron probes are coaxial reflector objectives, which have the advantage of allowing simultaneous optical observation and X-ray analysis. Magnification 100-500 times.
2. X-ray spectrometer:
The electron beam bombarding the surface of the sample will produce characteristic X-rays, and different elements have different characteristic X-ray wavelengths and energies. The element being analyzed can be determined by identifying its characteristic wavelength or characteristic energy. The instrument that uses the characteristic wavelength to determine the element is called the wavelength dispersion spectrometer (spectrometer), and the instrument that uses the characteristic energy is called the energy dispersion spectrometer (spectrometer).
Probe connectors: What are the advantages of the probe?
1, all parts are vacuum coating, hard gold hard nickel, thick gold thick nickel. The coating resists abrasion, maintains stable resistance and excellent contact conductivity.
2, the needle rod after heat treatment, increase the hardness and toughness.
3, meet the requirements of RHOS.
4, needle tolerance is small, high hardness; Fatigue resistance of springs.
5, imported lathe: small tolerance, good gloss.
6, precision assembly mold: the finished product has small vibration and smooth sliding.
7, corrosion: increase the adhesion of the coating; Both ends of the same detector.
8, some different materials; Different plating thicknesses. To ensure all wear resistance and durability.
