Description
Technical Field
The utility model relates to the technical field of alignment of a coating machine die head, in particular to an auxiliary alignment device of a coating machine die head and a coating machine die head.
Background
The manufacturing of lithium ion battery pole pieces requires the use of an extrusion coater, the die section of which typically includes an upper die, a lower die, and a gasket between the upper die and the lower die. A glue inlet and a glue outlet are arranged between the upper die head and the lower die head, and the glue outlet is provided with a die lip contacted with the surface of the foil. The alignment of the lips is an important indicator and the upper and lower dies must be in parallel alignment when installed properly. Poor die alignment can lead to uneven coating, excessive thick coating of partial areas, excessive thin coating of partial areas, deviation of coating surface density, and great increase of reject ratio. The uneven coating of the pole pieces can affect the subsequent assembly process and ultimately the performance and life of the battery. Poor die alignment can also lead to increased wear on the coater equipment, increasing equipment maintenance costs and frequency of replacement.
At present, an alignment mode of an upper die head and a lower die head in the industry generally adopts a mode that when the upper die head and the lower die head are closed, a positioning column of the upper die head is naturally inserted into a positioning hole of the lower die head, measurement adjustment is manually carried out by using measuring instruments such as a vernier caliper, and finally, a limiting block after the die head is used for fixing. This approach has high demands on the experience of the operator on the one hand and large errors on the other hand. If the upper and lower dies are unqualified, poor parallelism can lead to a series of problems: poor alignment of the die heads can cause uneven coating, excessive thick coating of partial areas and excessive thin coating of partial areas, deviation of the density of the coated surface, and the performance and the service life of the battery are influenced while the reject ratio is increased; poor die alignment can also lead to increased wear on the coater equipment, increasing equipment maintenance costs and frequency of replacement. Therefore, maintaining good alignment of the die heads of the lithium battery pole piece coater is important for ensuring coating quality, improving production efficiency and reducing maintenance cost.
