Fish skin separation method based on three-dimensional scanning

Abstract

The invention discloses a fish skin separation method based on three-dimensional scanning, which is based on a fish skin separation device. The fish skin separation device comprises a holding mechanism, a circular cutting knife (1), a separation knife (2) and a skin-stripping mechanism (3). The holding mechanism comprises a gill hook (4) and a tail clamp mechanism (5). The circular cutting knife is arranged at an eccentric position of a central axial line between the gill hook and the tail clamp mechanism. The separation knife and the skin-stripping mechanism are arranged at the side of the gill hook. The fish skin separation method includes the steps of scanning fish body through a three-dimensional image to obtain circular cutting position and path, separation path, longitudinal cutting path and stripping path; holding the to-be-skinned fish body in a horizontal manner front-and-back by the holding mechanism, circularly cutting the fish body around the fish body through the circular cutting knife; separating fish skin from fish body by the separation knife being stretched into the fish body from cut marks at the circularly cut position; longitudinally cutting the fish skin in the length direction of the fish body by means of the circular cutting knife; and finally removing the fish skin by the skin-stripping mechanism. The fish skin separation method achieves automatic separation of the fish skin, increases stripping efficiency of the fish skin and avoids damage on the fish skin.

Description

technical field [0001] The invention relates to the technical field of fish skin peeling, in particular to a fish skin separation method based on three-dimensional scanning. Background technique [0002] Fish skin can be used as leather for high-end leather shoes, leather bags, clothing, etc., especially black fish skin, which is rich in nutrients, collagen and amino acids, and can be used as a nourishing food or burn treatment; at the same time, it can replace crocodiles, sharks, and snakes And other countries protect animal leather. However, at present, the peeling of black fish is almost all done manually, which has low efficiency, poor product consistency, and potential safety hazards. [0003] The manual peeling operation of the prior art generally is to divide the fish into two and remove the fish bones, and then use a knife to separate the skin and flesh. This process requires processing workers to accumulate long-term experience to complete, and the fish skin will ...
