[0002] Squids, as a kind of seafood with delicious and juicy meat, are widely loved by consumers. The processing volume and consumption volume of squids in China rank first in the world. In the existing technology, the grasping of squids can only be manually operated. When manually grasping squids, if grasped too tightly, the skin of the squids is easily damaged; if grasped too loosely, the squids will slip off. Not only does it need to be grasped again, but also the slipping of the squids is likely to cause damage to the squids. In addition, frequent manual grasping increases the labor intensity of workers. Moreover, although some squid automatic processing equipment has appeared on the market, the feeding of these equipment still requires manual picking of squids, adjusting the squids to appropriate positions and angles, and then placing them on the designated feeding stations for subsequent processing. Such a feeding method has low production efficiency and insufficient process automation, greatly increasing the labor cost and operation intensity. Summary of the Invention

After the robotic arm 6 clamps the squid through the squid clamping mechanism 4, adjusts the squid to a suitable position and angle, and then places the squid on the designated feeding station, realizing automatic feeding of the squid with an unknown posture after adjusting the posture. The robotic arm 6 adopts the existing technology, such as a six-axis robotic arm, which can control the squid clamping mechanism and the squid to adjust the posture of the squid in the air.

In this embodiment, a suction cup mounting plate is arranged on one side of the clamping support frame 17. The suction cup mounting plate is fixedly connected to the clamping support frame 17.

The body clamping plate 25 is as shown in the attached Figure 5 , the lower end of the body clamping plate 25 inclines downward towards the middle of the two body clamping plates 25 to better and more stably clamp the squid body. For the convenience of description, as shown in the attached Figure 1It is described in terms of orientation. The squid clamping mechanism 4 is arranged in the front, and the visual recognition mechanism 3 is arranged in the back. In the initial state, the squid clamping mechanism 4 is located directly above the conveyor belt 5. The conveyor belt driving motor 29 drives the conveyor belt 5 to move the squid forward from the back. When in use,

[0040] Step 1: Adjust the height and angle of the light sources 9 on both the left and right sides of the conveyor belt 5. Taking the adjustment of the light source 9 on the left side of the conveyor belt 5 as an example, by rotating the locking part, move the light source height adjustment plate 12 up and down. After adjusting to the appropriate height, lock the locking part, fix the light source height adjustment plate 12 to the visual support frame 8. Then, unscrew the set screw and rotate the light source angle adjustment plate 15 to adjust the angle between the light source angle adjustment plate 15 and the light source height adjustment plate 12. After the angle is appropriate, tighten the set screw. The set screw presses against the rotating shaft 16 to fix the angle between the light source angle adjustment plate 15 and the light source height adjustment plate 12. In this way, the adjustment of the light source 9 on the left side of the conveyor belt 5 is completed. Adjust the light source 9 on the right side of the conveyor belt 5 to the appropriate height and angle in the same way. After the adjustment is completed, the control system starts the camera 7 and turns on the light source 9.

The control system starts the downward pressure driving cylinder 28, and the clamping support frame 17 drives the squid body limit fixing component 19 and the squid tail limit fixing component 18 to move downward. The two body clamping plates 25 are located on both sides of the squid body. The two suction cups 20 come into contact with the two squid fins. The two ear handle clamping plates 22 are located on both sides of the ear handle between the two fins of the squid. The control system starts the vacuum generator 21, the ear handle clamping cylinder 23, and the body clamping cylinder 24. The two suction cups 20 adsorb the two fins of the squid, the ear handle clamping plates 22 clamp the ear handle of the squid, and the body clamping plates 25 clamp the squid body, clamping the whole squid. The control system starts the robotic arm 6, and the robotic arm 6 drives the squid clamped by the squid clamping mechanism 4 to move upward, completing the squid posture adjustment in the air. After the adjustment is completed, the robotic arm 6 drives the squid clamped by the squid clamping mechanism 4 to be placed at the designated loading station. The control system starts the vacuum generator 21, the ear handle clamping cylinder 23, and the body clamping cylinder 24 to release the fixation of the squid, realizing the automatic loading of the squid. After the loading is completed, the robotic arm 6 drives the squid clamping mechanism 4 to return to its original position;

[0042] Step 3: Repeat Step 2 until the specified number of squids are loaded;

[0043] Compared with the prior art, first, the present invention can stably clamp the squid by setting the squid clamping mechanism 4. The flatness of the squid fins during loading can be maintained through the suction cups 20. The ear handle of the squid is clamped by the ear handle clamping plates 22, improving the stability of squid clamping. The squid body is clamped by the body clamping plates 25 on both sides, firmly clamping the squid without breaking it, and the squid will not slip, and the squid will not shake during the loading process. Second, the present invention is provided with a robotic arm 6. The robotic arm 6 can achieve functions similar to those of a human hand. The robotic arm 6 drives the squid clamping mechanism 4 to clamp the squid and adjust its posture in the air. After adjusting to a suitable posture for loading, it is moved to the loading station and placed down, greatly saving the labor cost of manual loading and reducing the operation intensity. Third, the present invention is provided with a visual recognition mechanism 3. The squid is photographed by the camera 7 and then uploaded to the control system. The control system obtains information such as the position, angle, and ventral and dorsal postures of the squid individual, and then controls the actions of the robotic arm 6 and the squid clamping mechanism 4 to achieve adaptive feature recognition of squids with different positions, angles, and ventral and dorsal orientations, realizing automatic loading with a fast loading speed and high efficiency.

[0044] Due to adopting the above structure, the present invention has the advantages of ingenious structure, accurate and stable squid grasping, automatic squid posture adjustment, high loading efficiency, and low labor cost.
