Production method of multi-coil reel lithium ribbon

Abstract

The invention discloses a production method of a multi-coil reel lithium ribbon, which comprises the following process steps: a. Install the reel reel on a winding machine, connect the extruded lithium ribbon to one end of the reel, and start winding machine, complete a roll of lithium ribbon winding on the reel; b, move the reel on the winding machine to the area to be wound on the reel, connect the extruded lithium ribbon to the area to be wound on the reel, and start the winding machine, Complete the winding of a roll of lithium ribbon on the reel; c, repeat the previous steps, and wind multiple rolls of lithium ribbon on the reel in turn. The present invention is suitable for large-scale automation equipment, with less loading and unloading, less joint tail loss, convenient packaging, saving transportation costs, saving downtime and reeling time and saving lithium belt joint loss, and the lithium belt on the reel can be used separately. It can be used as a whole, and it can be applied to the simultaneous production of multiple production lines, which improves the work efficiency, and can reduce the additional weight of the lithium ribbon winding machine, making the winding more stable and reducing the winding error of the lithium ribbon.

Description

technical field [0001] The invention relates to a production method of a metal lithium strip, in particular to a production method of a multi-coil reel lithium strip. Background technique [0002] Existing metal lithium products, especially battery-grade lithium, mostly appear in the form of blocks when they are formed into finished products. The forming efficiency of lithium blocks is low, and storage and transportation are inconvenient. In addition, during subsequent processing, such as making lithium batteries, a single lithium block will also reduce processing efficiency and slow down processing speed. [0003] In order to solve the above-mentioned technical problems, Chinese Patent No. 200420105464.0 discloses a reel lithium ribbon, the application date of which is December 7, 2004, and the authorization announcement date is December 28, 2005, which includes a lithium ribbon and a reel, lithium It is wound on the reel in a continuous spiral shape, and the reel is in th...

Problems solved by technology

However, there are still the following problems in the production of reel lithium strips in this way: one, because the reel adopts an integral structure, only one reel can be wound on the reel shaft. The net weight of a lithium belt does not exceed 500 grams, and the efficiency is low

2. When used, multiple joints will be generated on the large-scale automatic production line, which will waste lithium leading and tailing and reduce production efficiency.

3. The method of winding a lithium belt with an integral structure is not suitable for large-scale automation equipment. There are many ups and downs, many joints are lost, and more time is required for downtime and loading, which affects production efficiency.

Multi-connectors are produced on large-scale automatic production lines, which wastes the head and tail of lithium tape. One reel of lithium tape is only suitable for one production line, and the production efficiency is low. Therefore, the existing reels are only suitable for ordinary lithium battery production lines in the past. Lithium battery production line has certain limitations
