The invention discloses a pre-winding mechanism for a winding machine and relates to the technical field of mechanical equipment. The pre-winding mechanism has a left mounting base and a right mounting base. A left pre-winding cylinder is installed on the left mounting base, and a right pre-winding cylinder is installed on the right mounting base. The left pre-winding cylinder and the right pre-winding cylinder are each provided with guide rails on both sides. The guide rails are installed on the mounting bases. The guide rails are provided with roller mounting bases. The left roller mountingbase is provided with a bidirectional roller. The right roller mounting base is provided with a bidirectional rubber-covered roller. The left roller mounting base is connected with the left pre-winding cylinder. The right roller mounting base is connected to a right pre-winding cylinder. The mounting bases are also provided with motor mounting bases on which motors are mounted. The motors are connected to synchronous pulleys through synchronous belts. The synchronous pulleys are connected with the bidirectional roller. The motors drive a pre-winding roller to proactively rotate and feed and synchronize the linear speed with a winding needle, maintain low tension of the head in the pre-winding and winding processes, and improve the quality of a battery cell.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a pre-winding mechanism for a winding machine. Background technique [0002] When the current lithium-ion battery automatic winding machine is winding, the pre-rolling mechanism is fully opened after the pre-rolling of the positive and negative electrodes is completed or a little gap is left (such as figure 1 ), and then the winding needle winds the pre-set length according to the process and cuts the glue to form a battery core. The pre-winding roller of the pre-rolling mechanism needs a one-way bearing to cut off the tension to prevent the pole piece from retreating. During pre-rolling, the pole piece diaphragm is rolled into the surface of the needle by the rotation of the needle. For circular winding, especially for winding needles with small diameters, the tension is particularly high during pre-rolling, and the head of the pole piece is likely to be discounted...
