[0037] The present invention is a self-rotating chain conveyor device for sandblasting precision parts, which mainly includes components such as a body 1, a self-rotating chain 3, a self-rotating wheel 6, a conveying chain 7 and a self-rotating rod 61. The body 1 serves as a supporting structure, on which a working panel 11 and a self-rotating chain 3 are provided. A plurality of transmission pins 31 are vertically and spaced apart on the self-rotating chain 3 for transmitting power. A plurality of self-rotating wheels 6 are provided on the side of the self-rotating chain 3, and these self-rotating wheels 6 are driven to move by the same conveying chain 7. The gear teeth of the self-rotating wheel 6 match the gaps between two adjacent transmission pins 31 to realize the self-rotation of the self-rotating wheel 6 during movement. A self-rotating rod 61 is vertically provided on the end face of each self-rotating wheel 6, and the self-rotating chain 3 drives the self-rotating wheel 6 and the self-rotating rod 61 to rotate together through the transmission pin 31. When in use, the precision parts to be sandblasted (such as 3C product shells such as mobile phone shells and tablet shells) are fixed on the self-rotating rod 61 by a sandblasting jig 8. As the conveyor chain 7 moves, the rotating wheel 6 and the rotating rod 61 move the product along, rotating as they go. This combination of rotation and movement ensures that all sides and the outer surface of the product are evenly and thoroughly sandblasted, ensuring consistent sandblasting quality and consistent coverage.

[0038] To sum up, the self-rotating chain conveyor device for sandblasting of precision parts of the present invention aims to realize the synchronous rotation and movement of the product during the conveying process through innovative design, thereby ensuring the uniformity and high coverage of sandblasting around the product and on the outer surface, improving the sandblasting efficiency and product quality.
