Automatic cover plate welding and rubberizing machine

Abstract

The invention discloses an automatic cover plate welding and rubberizing machine, which comprises a machine frame and a workbench arranged on the machine frame. The machine further comprises a rotating disc, a rotating disc driving device, eight positioning fixtures uniformly arranged at intervals at the outer edge of the rotating disc along the circumferential direction thereof, an electrical core loading robot, a cover plate loading manipulator, a cover plate shaping assembly, an anode welding assembly, an anode rubberizing assembly, a cathode welding assembly, a cathode rubberizing assembly, and a blanking robot. Each positioning fixture comprises an electrical core positioning mechanism used for positioning the position of an electrical core, and a cover plate positioning mechanism used for positioning the position of a cover plate. The electrical core loading robot, the cover plate loading manipulator, the cover plate shaping assembly, the anode welding assembly, the anode rubberizing assembly, the cathode welding assembly, the cathode rubberizing assembly, and the blanking robot are arranged on the workbench and are sequentially arranged at intervals at the periphery of the rotating disc along the circumferential direction thereof. According to the technical scheme of the invention, by means of the cover plate welding and rubberizing machine, the full automatic operation of the welding and the rubberizing of battery cover plates and electrical core tabs can be realized. Meanwhile, the problem in the prior art that an electrical core tab can only be welded and rubberized after being manually wrapped into a cover plate flexible connection sheet and then shaped in the prior art can be solved. The labor cost is saved and the production efficiency is improved.

Description

technical field [0001] The application relates to the field of lithium-ion battery production equipment, in particular to a fully automatic cover plate welding and gluing machine. Background technique [0002] Lithium-ion battery is a large-capacity, high-power battery that has been widely used in digital products and electronic equipment. A lithium-ion battery includes a battery cover assembly, a battery casing, an electrolyte, and a battery core wound by positive and negative electrodes and separator paper. [0003] In the traditional cover plate welding and gluing machine, the battery cover plates need to be manually placed on the assembly line one by one, and then grasped by the manipulator to the fixture, and welded and glued together with the battery cells. In this way, a machine needs a special person to watch the machine loading, and the labor cost is high. In addition, with the latest battery technology, the soft connection piece of the cover plate needs to be wra...

Problems solved by technology

In this way, a machine needs a special person to watch the machine loading, and the labor cost is high

In addition, with the latest battery technology, the soft connection piece of the cover plate needs to be wrapped around the tab of the battery cell for welding and pasting. The previous equipment cannot meet this requirement.
