## Background
TECHNICAL FIELD
The invention relates to a lithium ion battery, in particular to a compound paper sticking process for lithium ion battery fuses.
BACKGROUND OF THE INVENTION
In the prior art, a piece of compound paper needs to be stuck respectively on a Ni sheet and a Ni/Al cladding strip at the two sides of a lithium ion battery fuse. The two pieces of compound paper have edges of different shapes. One piece of compound paper is square and the other piece is of L shape. Currently, the compound paper is taken manually from the release paper and then stuck on a product. Manual operation is required for twice respectively for tearing out the compound paper and sticking compound paper. Two pieces of compound paper are stuck on a product. In accordance with the requirement of the product, the misplacement of upper and lower layers of the compound paper stuck should be less than or equal to 0.3 mm. The clearance between the compound paper and the product is less than 0.2 mm. Two pieces of compound paper of different shapes are stuck respectively on the Ni sheet and Ni/Al cladding strip of the fuse, increasing the difficulty of manual sticking of compound paper, decreasing speed, making the station of compound paper sticking the bottleneck of the whole production and requiring more personnel for increasing the output. The production efficiency is low. Manual operation cannot achieve accurate positioning, resulting in lots of products needing rework and defective products. Handwork is highly relied on. Two pieces of compound paper needs to be stuck in sequence in each procedure, requiring excessive working hours.

d) starting the semi-automatic compound paper sticking machine and letting the compound paper of the tape with battery fuse move forward; taking down the battery fuse which moves to a rewinding shaft at the other end of the semi-automatic compound paper sticking machine and obtaining a semi-finished product.
The compound paper tape is formed by the composite of square compound paper and L-shaped compound paper.
The compound paper on the battery fuse is shaped manually for the semi-finished product.
A plurality of battery fuses are stuck on the compound paper tape simultaneously when the compound paper tape stops for one time in step c).
Battery fuses in step c) are stuck on the compound paper of the compound paper tape simultaneously or on the compound paper of the compound paper tape successively.
The semi-automatic compound paper sticking machine is provided with a bench. One end of the bench is provided with a first bracket. The upper part of the first bracket is provided with a feeding rotating shaft. The lower end of the first bracket is provided with a first guiding shaft. The other end of the bench is provided with a second bracket. The upper part of the second bracket is provided with a waste rewinding shaft while the lower part of the second bracket is provided with a second guiding shaft. The lower end of the second bracket is provided with a fetching roller. The outer side of the bench is provided with a drive motor connected with the shaft of the fetching roller. A driving device is arranged between the roller shaft and the waste rewinding shaft. The middle part of the bench is provided with a work platform. One end of the fetching roller a sensing plate and a corresponding sensor. The sensor and the drive motor are connected with a control device.
The fetching roller is provided with a polygonal cross section, which is convenient for taking out the battery fuse.
The fetching roller is provided with a pentagonal cross section.
The driving device comprises a big pulley arranged on the roller rotating shaft and a small pulley arranged on the waste rewinding shaft. A driving belt is arranged between the big pulley and small pulley, which is convenient for synchronous operation with the roller rotating shaft.
The bottom spacing of the bench is provided with a supporting seat, which facilitates the stable operation of the bench.
The invention has advantages that a plurality of battery fuses can be stuck on multiple pieces of compound paper simultaneously. The invention changes prior process of sticking compound paper on battery fuses into a process of sticking battery fuses on compound paper, which improves the accuracy and efficiency of compound paper sticking, causes work done by multiple personnel to be done by two personnel and saves labor and time required. Special compound paper is used for facilitating accurate positioning and avoiding incorrect sticking. The principle of positioning of a sensor solves the problem of defective dimension, thus leading to smooth operation without manual adjustment, maintaining operation at a relatively low class without changing labor force and reducing 40%-50% of working hour.
