The first step: the fish body 11 is placed behind the conveyor belt device 1 and the conveyor belt is started, and the conveyor belt device 1 transports the half-cut fish body 11.

_{Step 2: Calculate the time t 0} for the fish body to pass through the scanning device;

9, in particular a shield half fish emitter 15 and optical instruments recorded at t ₁ long shutter time, the fish passes through the hollow portion after unblocking optoelectronic devices emitter 15 is recorded as t _2, the other half of the fish Secondly block the photoelectric instrument transmitter 15 and record the second blocking time t ₃ , and the moving speed of the fish body is V.

The roller 22 guides the blade 20 to perform peeling work on the fish body 11 until the head of the fish body 11 (starting point), and then repeat the fifth step.

Step 7: Reset the first actuator and reset the clamping device. Specifically, the magnetic coupling rodless cylinder 13 drives the tool device to move and reset. The piston of the cylinder 5 retreats and drives the active clamping part 9 to retract along the rotating shaft 30.
