A flat pressing device for lithium battery

Abstract

The invention discloses a flat pressing apparatus used for a lithium battery. The flat pressing apparatus comprises a fixed box; the top of the inner wall of the fixed box is fixedly connected with a first motor through a supporting plate; the output shaft of the first motor is fixedly connected with a first belt wheel through a coupling; the surface of the first belt wheel is in transmission connection with a second belt wheel through a belt; a threaded rod runs through the middle part of the second belt wheel; movable blocks are in threaded connection with the two ends of the surface of the threaded rod respectively; fixed blocks are fixedly connected with the bottoms of the movable blocks; the surfaces of the fixed blocks are rotationally connected with rotary rods through movable parts; and one ends, far from the fixed blocks, of the rotary rods are rotationally connected with a fixed base through the movable parts. The flat pressing apparatus used for the lithium battery relates to the technical field of the lithium battery, and solves the problem that the existing flat pressing apparatus used for the lithium battery cannot perform good extrusion and forming and the problem of low flat pressing speed of the lithium battery; and by adoption of the flat pressing apparatus, the production efficiency of the lithium battery is improved, the flat pressing quality of the lithium battery is improved, and rapid and effective production of the lithium battery is ensured.

Description

Technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a flat pressing device for lithium batteries. Background technique [0002] Lithium battery is a kind of primary battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. It is different from rechargeable battery. Lithium ion battery is different from lithium ion polymer battery. The inventor of lithium battery is Edison. Due to the very active chemical characteristics of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment has been increasing. , Put forward very high requirements for the power supply, and then the lithium battery entered the large-scale practical stage. [0003] In real li...
