[0002] As automotive electronic products continue to be updated and upgraded, customers have increasingly stringent requirements for product quality, which has led to higher requirements for quality control in the product manufacturing process, driving the continuous improvement of the automation level of assembly lines.

[0003] In the assembly line of automotive electronic product parts, the traditional method of loading parts is manual loading, where several parts are placed on a material tray, and the parts are manually picked up and placed on the product. However, there are risks such as bumps, missed placement, and ESD (Electro-Static discharge) failure in this process, which will affect the manufacturing quality of the product, thereby limiting production efficiency and requiring more labor costs.

[0004] Therefore, automatic loading equipment has appeared on the market. The material trays containing parts are transported one by one through the conveyor belt, and the parts in the material tray are clamped onto the product by a robot. However, when clamping the parts, the parts and the material tray are relatively close, which may easily cause the material tray to move when the parts are taken out, affecting the subsequent material retrieval. In addition, the existing material tray loading method makes the overall equipment large in size and occupies a large area. Summary of the invention
