The lithium iron phosphate battery pack production process is divided into three working segments, one is the electrical core production, the third is the battery pack. In the production process of lithium iron phosphate battery pack, the pole production is based, the battery is made is the core, battery pack is related to the quality of lithium battery finished products. Lithium iron phosphate battery pack method 1, use the appropriate battery, the cell type, voltage, internal resistance needs to match, please balance the battery before assembly.
Shear electrode and punch. 2, calculate the distance according to the hole, the scripture insulating board. 3, on the good screw, use the flange nut to prevent the nut from falling off, good screws are good, you can fix the lithium iron battery pack.
4, when connected and soldered, connect the voltage collection line (equalization line), do not take the protective plate to avoid accidental burning. 5, insulating silica gel is fixed again, this silica gel time is curing. 6, place the protective board, if you forget to do the balance of the battery, this is the last chance before the lithium battery pack, you can make a balance through the equalization line.
7, use the insulating plate to fix the entire lithium iron phosphate battery group, encapsulated by nylon tape, nylon tape is more stress, please pay attention to the outer casing of the steel material, the outer shell of the steel material is very beautiful, but the core combination is very It is difficult to guarantee that some housings are not treated, which is likely to scratch the battery cell, or even cause an accident because of insulation. 8, re-encapsulate the battery, please keep the battery and protective board, our battery cells are measured by 1 meter height and still guarantee normal work. 9, the final package is completed, the output input is used in silica gel wire.
Because it is a lithium battery, 48V20AH lithium battery pack, the battery pack is 9 kg, the weight is half the same acid battery. 10, the tutorial is completed, we have detected after the lithium phosphate battery pack, can meet our requirements. What are the process steps of lithium iron phosphate batteries? 1.
Battery material treatment Some materials for secondary batteries, such as lithium ions, etc., require special treatment. The electrode should be treated at high speed, and the fragile active substance is not damaged.
In electrolytes, it is necessary to special consideration to prevent precipitation and corrosion gas. 2. Cam unit If the machine is used to use a cylinder or AC servo actuator, it is difficult to maintain a stable state even when the beat time is less than 1 second.
Then, the cylinder reaches its operating distance in the short term, so its maintenance cycle is short. In the cam mechanism of the machine, you can solve this problem because all drives are kept by the smallest motor. 3.
Installation and bases are very important for mechanical establishment and foundation for long-term retention stability. Installation and base can shorten the startup time by maximizing the accuracy deviation of transmission and transmission mechanisms. Usually, the use of aluminum frame is canceled.
Construct stable foundation using the substantive foundation of thick square logs and tank manufacturing processes. For various requirements, annealing can be performed and a mount with additional precision can be used. 4.
Vacuum treatment not only has a simple vacuum chamber and stove, but also has a vacuum chamber operation process and a mechanism for liquid application equipment. There is a wealth of knowledge of special vacuum equipment and parts such as vacuum pump, pipeline and valve. 5.
Accurate positioning must have the positioning techniques and experiences that want to have, and can achieve efficient processing calibration systems according to the needs of mechanical positioning and image processing. In order to maintain the accuracy for a long time, the control of the camera or positioning station also implements precise positioning, including installation design. 6.
If the laser welding can, if it is possible, according to the needs of the individual, for example, CO2, YAG, LED, fiber, etc., such as laser welding, throttling valve shell and cover welding, resin, such as lithium iron phosphate battery thin foil. Welding instead of metal, etc.
Suitable welding method based on specifications and selection of welding machines. 7. Pressing the technical and experience of various press, such as air, hydraulic and servo, etc.
We have a wide range of results that are pressed from the mechanical arm of test production to the machine platform, produce high-precision and high quality control speed products and torque with servo motors. 8. Size measurement using a laser displacement, image processing apparatus, contact and non-contact sensor, etc.
In the production machine, only the measurement device cannot measure the correct size. Therefore, we must maintain accuracy, including installation vibration, etc. Prior to the assembled lithium phosphate battery pack, it is necessary to calculate according to the product size and the required load capacity of the lithium battery pack, and then calculate the capacity of the lithium battery pack required to assemble according to the capacity required by the product, then Pick the lithium battery according to the calculation results.
