PACK battery technology solutions and equipment: current, power lithium battery industry has become an important part of the development of the national strategy, the next 5 to 10 years, the industry will achieve self perfection and development of ecological industry, market opportunities and great potential, the industrial scale is expected to exceed 160 billion yuan. Portable energy storage battery pack Opportunities have great potential 2017 lithium battery pack enterprises do not lose but after more than 40 years of research and development, application of laser technology in the lithium battery industry is becoming more and more popular, has become increasingly mature technology, advanced manufacturing method of light, machine, electricity, computer and other disciplines of materials technology, as a new type of battery PACK solutions.
First, the powerful compatibility of PACK solutions.
1, the domestic laser market started later than the developed countries about 20 years, can be said that the domestic laser industry in 1995 and has just started, review our laser equipment during this 20 years, but it is not up to the contention of a hundred schools of thought, All flowers bloom together. degree, most of the equipment has single function, poor compatibility, brought great inconvenience to the use of user.
A new type of battery PACK 2, this paper introduces the solution with strong compatibility and strong practicability, can be perfectly compatible with PACK, PACK and welding soft square cylindrical PACK. This scheme uses a unique Longmen five axis structure (Figure 1), the U and V axes are used as the movement between the cores, and the X and Y axes are used as laser path movements, and the Z axis is used as the focal length adjustment, almost without any form of incoming material restriction.
Excellent positioning function of two and PACK solutions.
PACK battery factory often some laser equipment in the face of some different materials, is powerless, welding quality is rapidly decreased, and the scheme provides a good solution to this problem, a high resolution CCD camera on the U axis and V axis, so that U can not only be used as mobile power pool. Can effectively capture the welding position, the deviation of incoming effective feedback to the control system, to achieve the perfect localization of X, Y direction (Figure 2).
Three, PACK solution unique compression method.
1, PACK solutions in order to improve the quality of welding equipment, will be equipped with a pressing positioning device of laser welding, pressing the traditional way is relatively battery positioning, after a period of time, the cumulative error of fixture deviation caused by positioning, seriously affect the quality of welding. Even more inconvenient is that, when using this compression method, if the material changes, the entire fixture must be redesigned, change type time greatly extended.
2, the PACK solution provides a unique way of pressing, pressing with single batteries, namely each welding position for electric core pressure head pressure, the influence of fixture error caused by reduced to a minimum, and, when the incoming changes, just need to adjust the structure of the pressure head. Greatly improve the production efficiency.
Excellent altimetry performance of four and PACK solutions.
1, because the battery each welding position height can not be completely consistent, in order to achieve favorable welding effect, focal length follow body is essential, the welding position in each axis, Z can do fine tune the laser welding head is fixed on the focal length of this 14.8V lithium battery will be smooth and the efficiency is also improved.
2, the use of altimetry mechanism scheme (Figure 3), which is different from the traditional altimeter battery plane positioning mechanism relatively, but the measurement of the pressing mechanism of laser displacement sensor and a pressure head position, pressure to each head height change under pressure feedback to the control system, according to the change of the height of the Z axis to adjust its position in order to achieve the purpose of focal length, follow.
Five, PACK solutions, conclusions and outlook.
1, PACK solutions X, Y direction positioning and real-time system to achieve the Z axis following the welding trajectory of the perfect location, unique Longmen five axis structure makes the device almost without any incoming restrictions, but there are other factors that influence the quality of welding, such as welding speed, laser power, laser frequency and other factors. Therefore, the future development direction of domestic laser industry, not only improve the equipment structure, should also pay attention to the development of mechanical products, to improve the welding speed and welding stability, laser should learn foreign advanced manufacturing technology, in order to achieve the sublimation of welding process.
2, nowadays the laser industry should be combined with traditional industries, manufacturing technologies to transform traditional industries with advanced laser, not only to enhance the development of traditional industries, but also with the advantages of traditional industries, good agricultural lithium battery lithium products, make their own get broad space for development.
PACK solutions include battery PACK solve technology scheme and equipment PACK automation solutions, PACK solution skills, strong compatibility, PACK solutions of the superior positioning function, PACK solution unique pressing method, PACK solution scheme of altimetry performance excellent, view the sitemap, you can learn more automation lithium battery PACK related technology and equipment to solve scheme.
