The invention discloses a double-rod winding needle for lithium ion battery winding. The double-rod winding needle comprises a bottom plate, a support is fixedly arranged on one side of the upper end of the bottom plate, a motor is fixedly arranged at the upper end of the interior of the support through a mounting base, and a rotating disc is movably arranged on one side of the upper end of the support through a rotating shaft; the output shaft end of the motor is in transmission connection with a rotating shaft where a rotating disc is located through a coupler; connecting rods are movably arranged at the upper end and the lower end in the rotating disc in a penetrating mode; winding needles are fixedly arranged at one ends of the connecting rods, and clamping grooves are formed in the middles of the surfaces of the outer sides of the connecting rods; a rotating block is movably arranged in the middle of the inner side of the rotating disc through the rotating shaft; fixing blocks are fixedly arranged at the positions, at the upper end and the lower end of the rotating block, in the rotating disc; and clamping rods are movably arranged in the fixing blocks in a penetrating mode. The double-rod winding needle is good in use effect, the winding needle can be conveniently and rapidly replaced and installed, and therefore the effect of convenient use can be achieved.
Description
technical field [0001] The invention relates to the technical field of battery production, in particular to a double-rod winding needle for lithium ion battery winding. Background technique [0002] Lithium-ion batteries have the advantages of high operating voltage, high specific energy, long cycle life, and no environmental pollution. They are not only widely used in mobile communication equipment and portable electronic equipment, but also widely used in electric vehicles, electric bicycles and electric tools. In terms of large and medium-sized electric equipment, it is the main development direction of major battery manufacturers at present. [0003] At present, when the coil needles used for lithium ion production are in use, if the coil needles need to be replaced, it is more troublesome to replace. Each coil needle needs to be fixed by at least two screws, and it must be twisted when the whole is disassembled and installed. There are many screws, which is more troubl...
