Description
Technical Field
The invention relates to the field of lithium batteries, in particular to a device for detecting puncture of an isolating membrane.
Background
Currently, lithium battery enterprises worldwide are mainly concentrated in korea, china and japan. Japan monopolized the global battery industry for the interior of the vehicle before the 21 st century, and its main product was a secondary lithium battery. Later, a certain market is gradually occupied in the world with research and development of lithium battery production technology in korea and china. The foreign famous manufacturers of lithium batteries include Sanyo, Boshi, Samsung, Song, Sony, Toshiba, Ford, general, Benz, etc. These manufacturers typically have a complete lithium battery production line that includes lithium battery winding equipment and tab welding equipment, which are typically provided by specialized equipment manufacturers. According to investigation statistics, the scale of the lithium battery cell equipment in 2016 is 75 hundred million yuan, and the comparable increase exceeds 100%. The domestic equipment accounts for 55 billion yuan, and the domestic proportion is expected to be improved in the future. The capacity and performance of the conventional power battery can not meet the newly increased requirements of a terminal electric vehicle and an energy storage market, and the lithium battery equipment is increased at a high speed for 3-5 years in the future. The power battery is influenced by large-scale expansion of the power battery, the capacity of the single power battery is large, and the production efficiency and the performance of the lamination process are excellent. Many domestic leading cell manufacturers have production expansion plans for square aluminum shell batteries, and the demand for lamination process equipment is increased over 2016. In the lithium battery lamination machine equipment industry in China, the situation of cutting data in the past green forest and sanden is changed to the situation of cutting data in the present. Because the power battery has higher performance requirement and strict requirements on equipment stability, fineness, high speed and the like, high-performance equipment is preferentially considered in purchasing of enterprises, so that the market of acceleration equipment is centralized to a full-strength equipment enterprise, the competition of the low-end market equipment enterprise is increased, and small enterprises force the price reduction to take a path of thin profit and more sales for survival. The power lithium battery mainly comprises four parts, namely an isolating membrane, a cathode, an anode and electrolyte, and is mainly divided into three parts according to a forming process: sliced lithium batteries, laminated lithium batteries, and wound lithium batteries. In the sliced lithium battery, the isolation film is very soft, so that the alignment degree of the isolation film is difficult to ensure in the processing process, and the quality of the battery is reduced, so that the scheme is rarely used in the industry. The laminated lithium battery is structurally simpler in processing technology than a lithium battery processed by a slicing technology, because the isolation film is continuous in the whole lithium battery and the performance of the isolation film is almost the same as that of the sliced lithium battery, and the laminated lithium battery is commonly used in the industry to replace the sliced lithium battery. The square winding lithium battery has only one cathode pole piece and one anode pole piece in the whole battery, and the processing technology is simpler, so the winding lithium battery is widely applied at present.
The square winding lithium battery is almost used before the laminated lithium battery does not appear, but along with continuous research in the industry, along with the gradual increase of the energy density requirement of the battery, a battery core enterprise tends to make the battery larger and larger, and the single battery core has the main problems of safety, production efficiency, control of winding or overlapping of a pole piece and a diaphragm, production line collective efficiency and the like. The excellent performance of the laminated lithium battery is slowly presented, the popularization of the laminated lithium battery is a great trend in the future, the problem of the processing efficiency of the laminated lithium battery is a necessary way for popularizing the laminated lithium battery, and the laminating process can still be a mainstream trend along with the continuous innovation and progress of domestic laminated equipment enterprises and the transverse extension of large lithium battery equipment enterprises. GGII data of a high-industrial lithium battery research institute show that the soft-package battery loading capacity of China is about 3.99GWH in 1-10 months in 2019, the specified GWH is reduced by 10% on a same scale, and only accounts for 8.6% of the total loading capacity and accounts for 13.4% of the total loading capacity in the last year. The square battery has the machine loading of about 39.12GWH, is increased by 49 percent in the same ratio and accounts for 84.35 percent of the total machine loading.
The lamination process is a key process in the manufacturing process of the soft package battery, and the procedures of tab cutting, pole piece film covering, barrier film piercing detection and barrier film cutting are required to be carried out before lamination, so that the sheet-shaped film-covered pole piece is finally formed. The following technical difficulties need to be solved in the automatic design process of the barrier film piercing detection and barrier film cutting process: after the isolating film covers the surface of the pole piece, whether the isolating film is pierced or not in the transmission processing process needs to be detected, so that an isolating film piercing detection device needs to be designed for automatically detecting the piercing of the isolating film.
