The feed port 9, the feed conveying system of this embodiment also includes a feed conveyor belt 1 and a manipulator 3. Refer to the attached figure 1 and 2 , compared with the prior art, the present embodiment changes the vertical structure of the feeding tray 2 in the existing shrimp peeling machine body into a horizontal structure, that is, an annular surface 7 formed by the movement track of the shrimp trough 6 , the annular surface 7 is parallel to the horizontal plane; as figure 2As shown, the feeding port 8 is located on one side of the annular surface feeding tray 2, and the discharging port 9 is located on the other side of the annular surface feeding tray 2; the feeding conveyor belt 1 is installed On the side of the feeding port 8 of the feeding tray 2, and the length direction of the shrimp trough 6 located at the feeding port 8 is perpendicular to the conveying direction of the feeding conveyor belt; 10. The manipulator 3, which is grabbed and placed in the shrimp trough 6, is installed above the feeding conveyor belt 1 and the feeding tray 2.
[0087] In this embodiment, the technical solution changes the structure of the feeding tray 2, and changes the original vertical structure into a horizontal structure. Figure 11 and figure 2 It can be clearly seen that the structure of the feeding tray in the technical solution is obviously different from that of the feeding tray in the main body of the existing shrimp peeling machine. The effect is embodied in: without changing the length of the horizontal conveying section 13 of the feeding tray 2 in the main body 11 of the existing shrimp peeling machine, the horizontal feeding tray of this technical solution can increase the arrangement of the horizontal feeding tray in the case of the same length. Arrange the quantity of raw shrimp.
[0088] And if the body of the shrimp peeling machine in the prior art wants to add a set of feeding conveyor belt 1 and manipulator 3, without changing the structure of the feeding tray 2, the feeding conveyor belt 1 and manipulator 3 can only be set in the On the other side of the feeding tray 2 relative to the shell 12 of the shrimp peeling machine, refer to the appendix of the instruction manual. Image 6 ,Right now Image 6 The position shown in , this setting method is easily thought of by those skilled in the art, but this setting method, compared with the setting method of this technical solution, has defects, that is, this kind of arrangement will cause the movement of the manipulator 3 The longer the stroke, the lower the frequency of grasping by the manipulator, the conveying speed of the matching feeding tray 2 will also decrease, and the rotation speed of the active turntable component 29 matching the feeding tray 2 will also decrease, resulting in reduced shrimp peeling efficiency. . Specifically in:
[0089] Refer to the manual attached Image 6 , under the condition that the length of the feeding tray 2 of this technical solution and the shrimp trough 6 of the feeding tray 2 of the main body 11 of the shrimp peeling machine of the prior art are the same, the structure of the feeding tray 2 of this technical solution can shorten the length of the manipulator 3 movement itinerary.

Image 6 , the structure of the feeding tray 2 of the shrimp peeling machine body 11 of the prior art requires the manipulator 3 to move the shrimp tail 28 toward the side of the discharge port 9, and the distance it moves is L2, and the distance that the manipulator 3 moves in this technical solution is L1, by Image 6 As shown, L2 is obviously larger than L1, that is to say, in the same scenario, the vertical feeding tray 2 of the prior art will increase the moving stroke of the manipulator. However, this technical solution will shorten the moving stroke of the manipulator, so that the stroke of the manipulator 3 when placing the shrimp is shorter, the frequency of picking and releasing is faster, and the running speed of the feeding tray can be increased, so that the speed of the matching shrimp peeler can also be adjusted according to The speed of the feeding pan is correspondingly increased, making the shrimp peeling more efficient.

Since the manipulator action execution end 5 will shake to a certain extent, if the visual acquisition device 4 is set at the execution end, there will be more interference in the collected image information, which is not conducive to the accurate positioning of the manipulator execution end. In the technical solution, the visual acquisition device and the action execution device of the manipulator are separately set, which can effectively ensure the accuracy of image acquisition and the stability of the positioning and grasping of the manipulator.

The illustration in this application only shows a three-axis manipulator, which does not mean that only three-axis manipulators can be implemented, two-axis manipulators can also be implemented, and industrial robots can also be implemented. The components are all capable of implementing the technical solution.
[0107] In a further preferred technical solution, the execution end of the manipulator is provided with a suction cup 14.

Example Embodiment
[0111] Example 3
[0112] As another preferred embodiment of the present application, refer to the accompanying Figure 8 , the present embodiment provides a technical solution for the feeding and conveying method of an automatic shrimp peeling machine. The purpose of this technical solution is to solve the problems of poor automation, low feeding arrangement efficiency, Food safety and low efficiency of shrimp peeling. The technical solution adopts a manipulator for feeding, which can effectively realize the automatic feeding arrangement of raw shrimp, and can effectively improve the feeding arrangement efficiency of raw shrimp and the shrimp peeling efficiency of the shrimp peeling machine.
[0113] The technical solutions disclosed in this embodiment are as follows:
[0114] A feed conveying method for an automatic shrimp peeling machine, comprising the following steps:
[0115] Conveyor belt feeding step: the raw shrimp 10 is transported by the feeding conveyor belt 1 to the visual collection step;
[0116] The visual collection step: the image information on the feeding conveyor belt 1 is collected by the visual collection device 4, and the collected image information is sent to the manipulator grabbing code into the feeding step;
[0117] The manipulator grabs the code and enters the feeding step: the manipulator 3 receives the image information transmitted by the visual acquisition step, and according to the received image information, grabs the shrimp on the feeding conveyor belt 1, and places the grabbed shrimp on the feeding In the feed port 8 of the tray 2;
[0118] Shrimp storage and transportation steps in the feeding tray: The feeding tray 2 collects and stores the shrimp fed from the feeding port 8 , and rotates and transports it to the discharging port 9 .
[0119] In this technical solution, the processing process of the image information collected visually is the prior art, which generally includes the coordinate system of the visual collection device, the coordinate system of the manipulator, and the coordinate system of the target object. Convert the coordinate system of the target object to the coordinate system of the manipulator, and then convert the coordinate system of the target object to the coordinate system of the manipulator, so as to determine the coordinates of the target object, and the manipulator moves to the coordinates to grab the target object. In this process, the target object is Raw shrimp 10.
[0120] In this technical solution, the visual acquisition device 4 and the manipulator 3 exist independently, that is, the visual acquisition device 4 and the manipulator action execution device 5. The visual acquisition device 4 is separately arranged above the feeding conveyor belt 1, which can ensure the acquisition of The stability of the obtained image ensures the accuracy of the subsequent grasping and positioning of the robot.
[0121] The raw shrimp 10 is conveyed by the feeding conveyor belt 1. During the conveying process of the feeding conveyor belt 1, the visual acquisition device 4 collects the image of the raw shrimp 10 conveyed on the feeding conveyor belt 1, and recognizes the raw shrimp 10. The visual acquisition device 4 transmits the collected image information, raw shrimp position information and placement state information to the manipulator action execution device 5, and the manipulator 3 executes the manipulator action according to the received information. The execution end of 5 moves to the position of the raw shrimp 10, and adjusts the direction of the execution end according to the placement state of the raw shrimp 10. The execution end of the manipulator action execution device 5 grabs the raw shrimp 10 and moves the raw shrimp 10 to the feeding At the feeding port 8 position of the tray 2, the execution end of the manipulator action execution device 5 releases the grabbed raw shrimp 10, and the raw shrimp 10 automatically falls into the shrimp trough 6 at the feeding port 8 position, and the shrimp back 16 up.
[0122] In this technical solution, since the requirements for the placement of the raw shrimp 10 in the shrimp trough 6 are relatively strict, the manipulator is grabbing the raw shrimp 10 and placing the raw shrimp 10 in the shrimp trough. The requirements for positioning are also more stringent. If the placement position of the raw shrimp 10 in the shrimp placement tank 6 is not accurate, it will directly affect the working process and effect of the subsequent shrimp peeling step.
[0123] Preset the initial position information of the positioning reference point 22 on the robot arm 3 and the shrimp placement reference point 24 in the shrimp tank 6 in the feeding tray 2, and obtain the speed matching between the robot arm 3 and the feeding tray 2 according to the initial position information The visual acquisition device 4 collects the image data of the raw shrimp 10 on the feeding conveyor belt 1, and transmits the image data to the manipulator 3. The manipulator 3 receives the image data, and according to the image data, the execution end of the manipulator action execution device 5 is sent to the manipulator 3. The positioning reference point 22 on the top corresponds to the grasping reference point 23 of the raw shrimp 10; the manipulator 3 moves to grab the raw shrimp 10; after the execution end of the manipulator action execution device 5 locates and grabs the raw shrimp 10, the manipulator 3 moves according to the preset Move at a fixed speed, and place the raw shrimp 10 in the shrimp trough 6. At this time, the grasping reference point 23 of the raw shrimp 10 corresponds to the shrimp placing reference point 24 in the shrimp trough 6 to ensure that the raw shrimp 10 is located in the shrimp trough 6. The accuracy of the position in the groove 6 facilitates the smooth progress of the subsequent shrimp peeling process.
[0124] The shrimp placement reference point 24 of the shrimp placement trough 6 is formed by a positioning line 25 set in the shrimp placement slot. Generally, the second section of the shrimp tail is aligned with the positioning line.
[0125] When the execution end of the manipulator grabs the raw shrimp 10 and moves to the position of the feeding port 8 of the feeding tray 2, there are two positioning coordinate points, namely the first positioning coordinate point 20 and the second positioning coordinate point 21, and the execution end of the manipulator is at After grabbing the raw shrimp 10 and moving to the position of the feeding port 8 , the selection of the positioning coordinate point is determined by the state information of the raw shrimp 10 on the feeding conveyor belt 1 .
[0126] The specific performance is as follows: the structural features of the raw shrimp 10 include a shrimp back 16, a shrimp belly 19, a first side 17 and a second side 18. During the conveying process of the raw shrimp 10 on the feeding conveyor belt 1, they are all lying on the feeding conveyor belt. On the material conveyor belt 1, that is, the first side faces 17 or the second side 18 is upward, if the first side 17 is upward, the execution end of the manipulator 3 is grabbed on the first side 17, with the first side 17 facing Grab and move the raw shrimp 10 in the upper posture, when placed, the manipulator 3 corresponds to the first positioning coordinate point 20, the manipulator 3 moves to the first positioning coordinate point 20 to release the raw shrimp 10, and the second side 18 of the raw shrimp 10 is first connected to the The side surface of the shrimp trough 6 (the second shrimp trough plate 27) is in contact, and under the guiding action of the side, it slides into the shrimp trough 6, and when it slides down to the bottom of the prawn trough 6, the shrimp back 16 is formed. , The shrimp belly 19 is facing down, and the two side plates (the first shrimp tank plate 26 and the second shrimp tank plate 27 ) of the shrimp tank 6 are in close contact with the first side 17 and the second side 18 of the raw shrimp 10 respectively. If the state of the raw shrimp 10 on the feeding conveyor belt 1 is that the second side 18 faces upwards, the positioning point moved by the manipulator 3 after grabbing is the second positioning coordinate point 21 . After the raw shrimp 10 is released, the The first side 17 is in contact with the other side of the shrimp trough 6 (the first shrimp trough plate 26 ), and under the guidance of this side, the raw shrimp 10 slides down into the shrimp trough 6 , and then slides down to the prawn trough 6 . When the bottom is formed, the shrimp back 16 is upward, the shrimp belly 19 is downward, and the two side plates (the first shrimp trough plate 26 and the second shrimp trough plate 27) of the shrimp trough 6 are formed to be close to the first side of the raw shrimp 10 respectively. 17 and the state of the second side 18.
[0127] The three-dimensional coordinate system is established on the basis of the feeding tray 2, then the plane above the shrimp trough 6 is the XY coordinate system, the length direction of the shrimp trough 6 is the Y axis, and the moving direction of the shrimp trough 6 is the X axis, then the first Between the positioning coordinate point 20 and the second positioning coordinate point 21, the Y-axis position is the same, and the X-axis position is different.
[0128] When the raw shrimp 10 is conveyed on the feeding conveyor belt 12, the position and status information of the raw shrimp 10 on the feeding conveyor belt 1 are collected by the visual acquisition device 4, and the status information includes the direction of the shrimp tail 28, the first shrimp The orientation of the side 17 and the second side 18, the manipulator 3 rotates correspondingly according to the information collected by the visual acquisition device 4, to ensure that the positioning reference point 22 of the execution end of the manipulator corresponds to the grab reference point 23 on the raw shrimp 10 to ensure that the raw material is placed After the shrimps 10 are placed, the shrimp tails 28 of the raw shrimps 10 are exposed to the shrimp trough 6, and the directions are the same.
[0129] In the step of storing shrimp in the feeding tray, the annular surface 7 formed by the movement trajectory of the shrimp trough 6 for placing the raw shrimp 10 on the feeding tray 2 is parallel to the horizontal plane, and the raw shrimp 10 is moved from the feeding conveyor belt 1 by the robot 3 Grab it and place it in the shrimp trough 6 located at the feeding port 8 on one side of the feeding tray 2 . There are 9 feed ports.
[0130] In the step of storing shrimp in the feeding tray, the annular surface 7 formed by the movement trajectory of the shrimp trough 6 for placing the raw shrimp 10 on the feeding tray 2 is parallel to the vertical plane, and the feeding tray 2 includes at least one horizontal conveying section 13. , the raw shrimp 10 is grabbed from the feeding conveyor belt 1 by the manipulator 3, and placed in the shrimp trough 6 at the feeding port 8 on the side of the feeding tray 2, and the prawn trough 6 continues to move forward horizontally, moving To the discharge port 9 on the same side as the feed port 8.
