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

Embodiment Construction

[0032] A production method of a multi-volume reel lithium ribbon, comprising the following process steps:

[0033] a. Install the spool of the reel on the winding machine, connect the extruded lithium ribbon to one end of the spool, start the winding machine, and complete the winding of a roll of lithium ribbon on the spool;

[0034] 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, start the winding machine, and complete a roll of lithium ribbon on the reel;

[0035] c. Repeat the previous steps to wind multiple rolls of lithium ribbons on the reel in sequence.

[0036] The present invention also includes step d, the step d is installing protection disks at both ends of the reel, and engaging the protection disk with the reel.

[0037] The present invention also includes step e, the step e is installing a separator between two adjacent rolls of lithium ribbon on the reel.

Abstract

The invention discloses a production method of a multireel reel lithium tape, which comprises the process steps of: a. installing a scroll of a real on a winding machine, connecting an extruded lithium tape with one end of the scroll, starting the winding machine and finishing the winding of one coil of the lithium tape; b. moving the scroll to the area to be wound of the scroll on the winding machine, connecting the extruded lithium tape with the area to be wound of the scroll, starting the winding machine and finishing the winding of one coil of the lithium tape; and c. repeating such steps and winding a plurality of coils of lithium tapes on the scroll. The invention is suitable for large automation equipment, has advantages of less machine starting and shutdown numbers, little jointing waste and convenient packaging, can save transport cost, shorten shutdown and charging time and reduce jointing waste; besides, the lithium tape on the reel can be used both separately and integrally, which is suitable to the simultaneous production of multiple production lines, thereby improving the working efficiency; and moreover, the load of the lithium tape winding machine can be decreased, thereby realizing more stable winding and reducing lithium tape winding error.

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...
