Rotating wheel type adhesive tape attaching mechanism for lithium battery

Abstract

The invention discloses a rotating wheel type adhesive tape attaching mechanism for a lithium battery. The rotating wheel type adhesive tape attaching mechanism comprises a body, a rotating shaft, a first adhesive tape attaching assembly and a second adhesive tape attaching assembly, wherein the first adhesive tape attaching assembly and the second adhesive tape attaching assembly are oppositely arranged on the two sides of the body. One end of the rotating shaft is fixed to the body, and the other end of the rotating shaft is provided with a rotating gear externally connected with a driving source. The upper side and the lower side of the body are provided with an adhesive tape preparing station connected with an adhesive tape feeding device of a winder and an adhesive tape attaching station connected with a pole piece feeding device of the winder correspondingly. The first adhesive tape attaching assembly and the second adhesive tape attaching assembly on the body are driven by the rotating shaft to circularly rotate between the adhesive tape preparing station and the adhesive tape attaching station. The adhesive tape feeding device puts adhesive tape onto the first adhesive tapeattaching assembly or the second adhesive tape attaching assembly on the adhesive tape preparing station, and the first adhesive tape attaching assembly or the second adhesive tape attaching assemblyon the adhesive tape preparing station attaches the adhesive tape to a pole piece in the pole piece feeding device. Two suction cups of the first adhesive tape attaching assembly and the second adhesive tape attaching assembly circularly work between the adhesive tape preparing station and the adhesive tape attaching station, so the adhesive tape attaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery winding machines, in particular to a rotary wheel type gluing mechanism for lithium batteries. Background technique [0002] With the development and maturity of new energy technologies, the application of lithium batteries is becoming more and more extensive. In the current lithium battery equipment, the battery formed by combining and forming batteries in a winding manner is called a wound battery, and the wound battery is also called a battery cell. In the existing lithium battery automatic winding machine or film making machine, the glue paper is pasted on the pole piece through the glue sticking device. The glue sticking process of the pole piece needs to be prepared first and then glued. However, the traditional glue sticking device has only one station. The glue must be prepared after the glue application is completed, so the production efficiency is low, which reduces the output o...

In the existing lithium battery automatic winding machine or film making machine, the glue paper is pasted on the pole piece through the glue sticking device. The glue sticking process of the pole piece needs to be prepared first and then glued. However, the traditional glue sticking device has only one station. The glue must be prepared after the glue application is completed, so the production efficiency is low, which reduces the output of the battery cells and affects the benefits of the enterprise
