Description

Technical Field

[0001] This utility model relates to the field of material handling and detection technology, specifically a sorting device for small irregularly shaped parts. Background Technology

[0002] The inspection of material appearance and shape requires each material to be placed individually and in a uniform manner. During the material transfer process after processing, materials are typically stored in bins and then transported to the appropriate inspection points. However, the materials in these bins are often randomly piled up. While equipment such as vibratory feeders or elevators could be used to individually remove the randomly piled materials and then arrange them into a designated position using transfer devices, this approach may not be suitable for small, irregularly shaped parts. These parts would require manual removal and placement, necessitating significant manpower and hindering the automation of the production process.

[0003] In addition, some materials are manufactured using appropriate material trays with multiple holes for storage, which are then retrieved one by one by a robotic arm. However, this increases the investment in these material trays, and the material trays are not very versatile, requiring targeted production, which makes it difficult to reduce production costs.
