Abstract
The utility model relates to an ultrasonic oscillation roll, belonging to the technical field of battery manufacturing equipment, which comprises an upper roller (1), a lower roller (2), and a gap positioned between the upper and the lower roller for passing through a battery polar plate. The ultrasonic oscillation roll is characterized in that a piezoelectric ceramic (4) is positioned on the upper roller (1) or the lower roller (2), and the piezoelectric ceramic (4) is connected with a high frequency oscillation circuit. The ultrasonic oscillation roll has the advantages of making the flexibility of the polar plate excellent after rolling by means of vibrating the rollers during the rolling, producing no burr easily, reducing the deformation of the polar plate after rolling and improving the uniformity of the polar plate because the active substances of the battery polar plate are compressed fully and distributed evenly on the current collector.
Description
Technical field
The utility model relates to a kind of plant equipment, and especially a kind of battery production is used roller, specifically a kind of when rolling battery pole plates the using ultrasound wave height roll that vibrates frequently reach the supersonic oscillations of preparation high-performance pole plate to roller.
Background technology
At present, in the world each battery producer all adopt tradition to roller to roller, technological improvement concentrates on aspects such as the application, roll location control accuracy of size, the new roller surfacing of roller diameter.Tradition is to roller, and the pole plate after the processing can satisfy the requirement of present all kinds of cylindrical batteries substantially.But also there are some problems, as: pole plate degree of distorting is big, the active material distribution consistency degree is not high on the pole plate, has influenced the cycle life of battery with rectangular cell because of the consistency problem of pole plate with the HEV of this device fabrication, thereby is difficult to satisfy the requirement of HEV with the square MH-Ni battery of high-performance.
Summary of the invention
The purpose of this utility model is relatively poor to the uniformity that roller exists when producing rectangular cell at existing battery pole plates, the problem that the battery performance of serious restriction improves, and the supersonic oscillations that design a kind of pole plate uniformity good processability are to roller.
The technical solution of the utility model is:
A kind of supersonic oscillations are to roller, comprise topping roll 1 and bottom roll 2, be provided with the space by battery pole plates 3 between topping roll 1 and the bottom roll 2, it is characterized in that on described topping roll 1 and/or bottom roll 2 piezoelectric ceramics 4 being installed, piezoelectric ceramics 4 links to each other with high-frequency oscillating circuits.
Described piezoelectric ceramics 4 is (Bi1/2Na1/2) TiO3-Ba-TiO3 (being barium titanate bismuth sodium), PZT (being lead zirconate titanate), PLZT (being the lead zirconate titanate that lanthanum mixes), PZN-PT (being lead zinc niobate-lead titanates) or PMN-PT (being PMN-PT).
Described piezoelectric ceramics 4 or be square structure, or be cylindrical structural.
Described piezoelectric ceramics 4 or be positioned at topping roll 1 and/or the surface of bottom roll 2, or be inlaid in described topping roll 1 and/or the bottom roll 2.
The frequency of oscillation of the oscillating circuit that links to each other with described piezoelectric ceramics 4 is 20～40kHz.
The beneficial effects of the utility model:
The utility model adopts piezoelectric ceramics in conjunction with high-frequency oscillating circuits, as supersonic generator, thereby can make roll along with the high-frequency stretching, extension of piezoelectric ceramics with dwindle motion and vibrate.This equipment is mainly used in the battery pole plates roller compaction processes, rolls with traditional silent oscillation roller is compared, and oscillating mode of the present utility model makes roller vibration to roller in the process of rolling, and can make pole plate roll back pliability excellence, is difficult for producing burr; The abundant compacting of the active material of battery pole plates is evenly distributed active material on collector, roll distortion later thereby reduce pole plate, improves the uniformity of pole plate.Thereby this equipment is particularly suitable for the production of high-performance power battery plate, with the pole plate of this device fabrication, can satisfy the requirement of HEV, EV battery.
