Battery core automatic positioning, trimming and shaping production line and positioning, trimming and shaping process thereof

Abstract

The invention discloses an automatic battery core positioning, trimming and shaping production line and a positioning, trimming and shaping process thereof. The automatic battery core positioning, trimming and shaping production line comprises conveying guide rails, a material return guide rail, a feeding belt, a feeding mechanical arm, line changing mechanisms, a jig, a blocking, positioning andopening-closing mechanism, a battery core positioning mechanism, a trimming mechanism and a shaping mechanism. The number of the conveying guide rails is two; the material return guide rail is arranged between the two conveying guide rails; the feeding belt is arranged at the front end of the rack; the number of the line changing mechanisms is two, and the two line changing mechanisms are arrangedat the front end and the rear end of the conveying guide rails correspondingly; the jig is arranged on the line changing mechanisms; the blocking, positioning and opening-closing mechanism is arranged under the conveying guide rails corresponding to the station; and the battery core positioning mechanism, the trimming mechanism and the shaping mechanism are sequentially arranged at stations on the side part of the conveying guide rails from front to back. Automatic positioning, double-side cutting and shaping of the battery core are achieved, double-line machining production of the battery core can be conducted at the same time, material returning is completed through the material return guide rail, the productivity is effectively improved, and the positioning efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to an automatic cell positioning, trimming and shaping production line and its positioning, trimming and shaping processes. Background technique [0002] Lithium-ion secondary rechargeable batteries are composed of cells and protective circuit boards. The rechargeable battery is the cell without the protective circuit board. The cell is the storage part of the rechargeable battery. The quality of the cell directly determines the quality of the rechargeable battery. The battery production and processing process includes multiple process stations, which are usually completed on the processing line. With the upgrading and adjustment of domestic industries, automation transformation is an important way for enterprises to effectively increase production line production capacity, save costs, and improve competitiveness; for battery production For manufacturing enterprises, aiming at t...

Problems solved by technology

The traditional battery clamping fixture generally adopts the method of flipping and clamping or clamping and clamping through the spring block inside the fixture. In the process of picking and placing the battery, a separate fixture opening mechanism needs to be designed to open the fixture In order to take out the discharge core, it cannot be effectively linked with the jig positioning mechanism at the production line station. The opening and closing of the jig takes a lot of time, resulting in low production efficiency; the traditional jig uses the structure of the installation slot to place and limit the electric current core, because the battery core is mostly a sheet structure, after the battery core is placed in the fixture installation slot, it is inconvenient for the manipulator to pick and place

In addition, the traditional cell production line mostly adopts single-line processing. This kind of material transmission and wiring design of the whole line has limited capacity improvement in the same installation space, which has become a key bottleneck restricting the production capacity improvement of the whole line; The positioning mechanism set at the line station to position and fix the jig cannot be linked with the opening and closing structure of the jig, and the positioning efficiency is poor and time-consuming
