As a new type of clean energy, lithium batteries can not only provide power for new energy vehicles, but also provide power for various products such as electric trains, electric bicycles, and golf carts. The production of lithium-ion batteries is closely linked by one process step. The production process roughly includes pole piece manufacturing, battery cell manufacturing, and battery assembly. Among them, laser technology represented by laser welding is widely used in the manufacture of lithium batteries. Today, Leapion Laser will give you an analysis. What are the specific applications of   lithium battery laser welding machines  in  manufacturing? 1. Welding of battery explosion-proof valve The explosion-proof valve of the battery is a thin-walled valve body on the battery sealing plate. When the internal pressure of the battery exceeds the specified value, the valve body of the explosion-proof valve ruptures to prevent the battery from bursting. The safety valv...

  Today, every country in the world advocates technological innovation to improve product quality,   Jinghang   is a manufacturer of laser tubes, so where to start with technological innovation of   laser tubes ?   Laser tube is a device that emits carbon dioxide laser, has been developed in China for 30 years, especially after the rapid development of the last 15 years, can be said to be rapidly changing, carbon dioxide laser technology applied to various fields. Jinghang laser production and manufacturing laser tube also has a ten-year history, the laser tube technology improvement is always thinking. Laser tube technology is complex, high-tech content is also high, technical difficulties. The design of laser tube billet, laser tube gas proportioning, laser lens development are all difficult problems of laser tube technology, each link affects the quality of the laser tube, to improve the laser tube technology, we must improve the technology of these links, ot...

Even if you don't know them by name, most people are familiar with  printed circuit boards (PCBs) , or at least have seen them at some point in their lives. They are the thin green boards found in everything from TV remotes to washing machines, laptops, medical devices, and other electronics. What is less well known is the manufacturing process behind the assembly of PCBs. As the backbone of our modern lives, the  PCBA manufacturing  process has quality controls built in to ensure higher yields and lower failure rates.    If your job is related to manufacturing, electronics or semiconductors, it's useful to know how PCBA manufacturing works. Therefore, we have broken it down into component steps. 1. PCB Development The axiom of measure twice, cut once doesn't exactly apply to PCBA manufacturing, but the basic idea remains. Before a board can be approved for mass production, it needs to be properly designed and tested. Any defects need to be eliminated ...

What is rectifier module? A  rectifier module  is an electronic device that converts alternating current (AC), which periodically changes direction, into direct current (DC), which flows in only one direction. There are several types of rectifiers, including half-wave rectifiers, full-wave rectifiers, and bridge rectifiers. Half-wave rectifiers only allow one half of the AC waveform to pass through, while full-wave rectifiers allow both halves of the AC waveform to pass through, but in opposite directions. Bridge rectifiers consist of four diodes arranged in a bridge configuration, which allows them to rectify AC voltage from either direction. Rectifiers are used in a variety of applications, including power supplies for electronic devices, battery chargers, and DC motor drives. They are also used in power transmission and distribution systems to convert high-voltage AC power into lower-voltage DC power for use in homes and businesses. Application of rectifier module Rect...

TFT type display is currently the better LCD color display,   TFT type display   has many advantages: high response, high brightness, high contrast ratio, etc. TFT display is closest to CRT display. TFT screen is also often found on the screen of major cell phones, there are 65536 colors, 160,000 colors, 16 million colors, it is also very good display. TFT means that the LCD on the Each LCD pixel is driven by a thin-film transistor integrated behind it. This allows for high speed, high brightness, and high contrast display screen information. TFT-LCD (thin film transistor liquid crystal display) is one of most liquid crystal displays. Liquid crystal display (LCD) . the structure of LCD is placed in the middle of two parallel glass liquid crystal box, the substrate glass is set on the TFT (thin film transistor), the color filter substrate glass is set in, to the TFT signal, the voltage changes to control the direction of rotation of the liquid crystal molecules, so as to a...

   Features of Ni-Cd batteries Nickel cadmium (Ni-Cd or “nicad”) batteries were invented way back in 1899 by a Swede named Waldemar Jungner. At that time, porous electrodes housed nickel, which was crafted into pockets for a nickel cadmium mixture to sit in and conduct electricity through.  After decades of research and experimentation, smart people found out that the more surface area inside a battery, the better for stronger electric currents.  Therefore,  Ni-Cd batteries  now resemble a “jelly-roll” inside, with porous anode and cathode plates sandwiching a separator and rolled up into a tasty charge with maximum power output. At either end of an  Ni-Cd battery  is an electrode, the point at which electricity goes in and leaves. Ni-Cd batteries use an active material called nickel hydroxide at the positive terminal and metallic cadmium at the negative terminal. Inside is a liquid alkaline electrolyte solution, usually potassium hydroxide. Cadmi...

  1. What is the OPGW Cable?   OPGW cable, also known as optical fiber composite overhead ground wire. The optical fiber is placed in the ground wire of the overhead high voltage transmission line to form the optical fiber communication network on the transmission line. This structure has both ground wire and communication functions, which is generally called OPGW optical cable.   Spiral Vibration Damper   2. What is the ADSS Cable?   ADSS cable, also known as the medium messenger cable, is a kind of composed of medium material, its all contain the necessary support systems, can be directly hung on the electric power poles of non-metallic fiber optic cable, it is mainly used for overhead high voltage transmission system of the communication line, can also be used for lightning areas, large span and other overhead laying under the environment of communication lines.   Parts of ADSS Accessories Some of the main parts of  ADSS accessories  include th...
