[0012] In the above step 1, fresh, healthy, moderately sized fish suitable for processing are selected as raw materials, the fish heads are removed, and obvious stains and impurities on the surface are removed through preliminary cleaning;

[0013] In the above step 2, an automated device such as a robotic arm or a conveyor belt is used to automatically deliver the pre-processed fish to the processing area, and the fish body is clamped by a clamping plate;

[0014] In the above step 3, the slide moves to drive the fish body on the clamping plate to pass through the rotating cutter and the nozzle to remove the internal organs and clean it;

[0015] In the above step 4, the scale peeling process is performed using a material guide cylinder and a peeling knife;

The nozzle is connected to the high-pressure water flow, the first electric cylinder drives the clamp slightly to open, and the nozzle sprays high-pressure water to flush the fish belly, and the flushed internal organs and impurities fall into the first collection box for collection.

[0019] As a further technical solution of the present invention, in step four, after flushing is completed, the slide continues to move forward, the second electric cylinder drives the push rod to push out, and at the same time the first electric cylinder drives the clamp to open, the push rod flips the fish body, and the third motor drives the material guide cylinder to rotate. The front end material guide cylinder sends the fish body onto the peeling knife. The height of the mounting seat can be adjusted by adjusting the groove and the fastening bolt to achieve the best peeling effect. The peeling knife cuts the scaly fish skin to complete the separation of fish meat. The fish skin falls into the second collection box below through the through hole, and the rear end material guide cylinder transports the fish meat out.

[0020] As a further technical solution of the present invention, in the step five, the skinned fish meat is fed into between the meat collection drum and the rubber drum by the conveyor belt on the second base, and the meat collection drum and the rubber drum are driven to rotate by the fourth motor and the fifth motor, and the fish pieces are squeezed through the gap between them. This squeezing action causes the fish meat to be squeezed and dispersed, while the hard parts such as fish bones and fish bones remain in place because they are not easily squeezed. The crushed fish meat will pass through the fine holes on the meat collection drum. The apertures of these fine holes are usually carefully designed to ensure that the fish bones cannot pass through, and are collected inside the meat collection drum, and fall together through the meat scraper plate and discharged through the second discharge port, while the fish bones and fish bones are left outside the meat collection drum and are brought to the first discharge port by the rubber roller for discharge.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is designed with an integrated structure, which seamlessly connects all key links in the fish fillet processing process, ensures the high consistency and smoothness of the entire production process, and thus significantly improves the production efficiency. The design not only optimizes the transfer and waiting time in the traditional processing flow, but also further promotes the improvement of production speed through the automation mechanism, effectively reduces the dependence on manual operation, and greatly reduces labor costs. At the same time, the scale-peeling structure is adopted to realize the direct peeling of the fish body with scales during the processing process, which completely solves the problem of incomplete cleaning of fish scales and easy mixing into the finished product in the traditional method.

10. The automated processing technology for prefabricated boneless fish fillet according to claim 7, characterized in that: In the step 5, the skinned fish meat is fed into the space between the meat collecting drum (20) and the rubber drum (22) by the conveyor belt (18) on the second base (2), and the meat collecting drum (20) and the rubber drum (22) are driven to rotate by the fourth motor (19) and the fifth motor (21), and the fish pieces are squeezed through the gap between them. This squeezing action causes the fish meat to be squeezed and dispersed, while the hard parts such as fish bones and fish bones are not easily squeezed and remain in place. The squeezed and crushed fish meat passes through the fine holes on the meat collecting drum (20), and the apertures of these fine holes are usually carefully designed to ensure that the fish bones cannot pass through, and are collected inside the meat collecting drum (20), and are concentrated and dropped by the meat scraper (27) and discharged through the second discharge port (24), while the fish bones and fish bones are left outside the meat collecting drum (20) and are brought to the first discharge port (23) by the rubber drum (22) for discharge.
