Technical Field

[0001] The invention relates to the technical field of sheet material assembly, in particular to an automatic sheet material assembly machine. Background Art

[0002] In current industrial production, the sheet assembly process often relies on manual operation, which not only affects assembly efficiency but also increases labor costs. Specifically, the traditional sheet assembly method mainly relies on manual assembly of sheets onto the material strip one by one through positioning jigs. This method has several significant problems: First, manual assembly is relatively inefficient. Since it requires manual operation one by one, the assembly speed is limited by the operator's proficiency and physical condition, making it difficult to significantly improve production efficiency.

[0003] Secondly, the use of positioning jigs during manual assembly may cause deformation of the material strip positioning holes. After long-term use, the accuracy and stability of the positioning jigs may decrease, causing deformation of the material strip positioning holes, which in turn affects the quality and reliability of the product.

[0004] In addition, with the continuous development of industrial automation technology, people's requirements for production efficiency and product quality are getting higher and higher. Traditional manual assembly methods can no longer meet the needs of modern industrial production, so it is necessary to seek a more efficient and accurate automated assembly solution.

[0005] In view of the above problems, the market urgently needs an automatic sheet assembly machine that can automatically complete sheet feeding, film tearing, alignment, transportation and visual inspection processes. This automatic assembly machine can not only greatly improve production efficiency and reduce labor costs, but also reduce quality problems caused by improper manual operation through precise automatic control.
