Abstract

In sea cucumber production lines, manual sorting, de-sanding, and organ removing operations still predominate, severely limiting production efficiency and posing sig-nificant risks to product consistency and hygiene. This paper introduces a novel piece of equipment for sea cucumber sorting, de-sanding, organ removing, and washing. Em-ploying an innovative process of "automatic sand mouth removal + high-pressure water jet washing + hook-assisted organ removal," the equipment adapts well to sea cucum-bers of various sizes and conditions, offering high versatility and facilitating an auto-mated, efficient, and standardized processing workflow. Moreover, due to the high sensitivity to the sea cucumber's external shape and posture and the complexity of the background caused by residues during the de-sanding and organ removing process, which complicates the recognition of the sea cucumber's sand mouth, this study pro-poses a sand mouth recognition algorithm for complex backgrounds. Utilizing tiered recognition technology, the algorithm precisely locates the sea cucumber's sand mouth following the extraction of its position through artificial intelligence, significantly en-hancing the success rate of recognition. Experimental results indicate that the prototype of this equipment increases the speed of de-sanding and organ removing by 107.8% compared to existing integrated sea cucumber washing and cutting equipment. The cleaning effectiveness is excellent, with a high sea cucumber cleaning acceptance rate of 91%, which is an increase of 6.125% over manual sorting, de-sanding, and organ re-moving methods, and the work efficiency has increased more than ninefold, achieving the anticipated outcomes.

在海参生产线上，人工分拣除脏操作仍占据主导地位，这一现状严重制约了生产效率，也给产品的一致性和卫生带来了巨大风险。本文设计了一种新型海参分拣除脏清洗设备。通过“切割沙嘴 + 高压水冲洗 + 钩子辅助除脏”的创新工艺，对不同规格和状态的海参均具有良好的适应性，具备高度通用性，实现了海参的自动化、高效、标准化加工流程。同时，针对海参外形和姿态特征的高敏感度，以及除脏过程中产生的脏污导致背景复杂、海参沙嘴识别困难的问题，提出了一种复杂背景下的海参沙嘴识别算法。该算法利用分级识别技术，在提取海参位置后，通过人工智能精准定位海参沙嘴，显著提高了识别成功率。实验结果表明，该实物样机的除脏速度较现有海参清洗剖切一体化设备提升了107.8%；清洗效果良好，海参清洗合格率高达91%，较人工分拣除脏清洗合格率提高6.125%，工作效率提高9倍以上，达到了预期效果。
