Description

Technical Field

[0001] The present invention relates to the technical field of material sorting equipment, and particularly relates to a blowing type flexible disk. Background Art

[0002] Robots and vision recognition are now increasingly widespread in industrial production. In the feeding and picking processes of materials, intelligent picking operations are often carried out through the cooperation of a manipulator and a vision recognition module.

[0003] For some small sheet products with front and back sides, there are strict requirements for their placement orientation during their assembly or processing, such as being face up or back up. For the automatic feeding work of such products, as in the invention patent with the publication number CN113998398A previously applied by the applicant, usually, a flexible disk is first vibrated to disperse and turn over the materials in the flexible disk, and then, in cooperation with a vision system, based on the images captured by a camera, the positions of qualified products are screened and calculated, and finally, the manipulator grabs and moves them to achieve feeding.

[0004] However, when the current flexible disk vibrates, it often causes the overall vibration of the flexible disk. When the manipulator grabs materials, to prevent the impact on the grabbing accuracy of materials in the picking process, the flexible disk needs to stop vibrating, which slows down the working efficiency of the material recognition and grabbing system. Summary of the Invention

[0005] To solve the problems of traditional vibrating flexible disks, the present invention proposes a blowing type flexible disk, which can disperse and turn over materials without affecting the recognition and grabbing of other parts of materials, and speeds up the working efficiency of the material recognition and grabbing system.

[0006] The specific technical solution adopted by the present invention is as follows: A blowing type flexible disk, comprising: A breathable component, a disk body part, and a blowing and turning assembly; The disk body part has a circular structure, with an annular edge provided on its outer side and a connecting shaft body for connecting to an external motor provided below. The disk body part can rotate relative to the blowing and turning assembly through the connecting shaft body; The breathable component is arranged in the inner area within the annular edge of the disk body part; The blowing and turning assembly is arranged on one side of the annular edge of the disk body part. The blowing and turning assembly includes a blowing mechanism for upwardly conveying air flow.

[0007] The blowing and turning assembly includes a shielding cover body and a blowing base as the blowing mechanism. A plurality of air blowing holes are provided on the blowing base, and the air flow is conveyed upward through the air blowing holes.

[0008] The shielding cover body is in close fit with the upper edge of the annular edge.

[0009] The disk body part includes a connecting shaft body, a disk body base, and an edge housing serving as the annular edge. The edge housing is fixedly arranged above the disk body base. The outer side of the edge housing is a vertical annular wall, and its inner side has an arc-shaped slope structure.

[0010] The disk body base includes a number of fixed connecting rods. The connecting shaft body is arranged at the center of the disk body base and is fixedly connected to the disk body base through the fixed connecting rods.

[0011] The disk body part further includes a mounting ring. The mounting ring, the disk body base, and the edge housing are all provided with evenly distributed screw holes. The mounting ring clamps and fixes the air-permeable component above the disk body base by means of screw fixation.

[0012] There are a total of six fixed connecting rods. The fixed connecting rods are evenly distributed circumferentially and divide the disk body base into six fan-shaped areas of the same size. When the air-blowing and flipping assembly is arranged at the edge of the disk body part, the area covered by the air-blowing and flipping assembly on the disk body part is one-sixth to one-third of the total area of the disk body part, that is, one or two fan-shaped areas.

[0013] The air-permeable component is provided with a number of air-permeable holes, and the air-permeable holes are distributed on the air-permeable component at uniform intervals.

[0014] The air-blowing holes are distributed in a strip shape, a hole shape, or a mesh shape. The air-permeable component is an air-permeable plate or a gauze net.

[0015] The beneficial effects of the present invention are as follows: Through the synergistic action of the air-blowing and flipping assembly and the air-permeable component, controllable air flow flipping is realized in a local area, avoiding the material position deviation caused by traditional overall vibration, and significantly improving the detection accuracy of the visual recognition system for the orientation of the material. The disk body part adopts an integrated structure of fixed connecting rods and a connecting shaft body, combined with the interval design of the air-blowing and flipping assembly and the disk body base, so that the material can be flipped without affecting visual recognition, and it is ensured that the material is in a stable state during grasping, improving the accuracy and grasping efficiency of the overall material recognition and grasping system.

[0026] The present invention will be described in detail below with reference to the accompanying drawings

[0027] As shown in Figures 1 to 7 , Figures 1 to 7 This is the first embodiment of a blowing flexible disk. Its structure includes an air-permeable component 1, a disk part 2, and a blowing and flipping assembly 3. The overall shape of the disk part 2 is circular, with an annular edge at its outermost side, and a connecting shaft body 21 for connecting to an external motor is provided below it. The air-permeable component 1 is arranged inside the annular edge structure of the disk part 2, and the blowing and flipping assembly 3 is arranged close to the annular edge of the disk part 2

[0028] As shown in Figure 4 , Figure 5 , the disk part 2 includes a connecting shaft body 21, a disk base 22, and an edge housing 24. The connecting shaft body 21 is arranged in the vertical direction, and the connecting shaft body 21 is connected to the disk base 22 through a fixed connecting rod 221. There are a total of six fixed connecting rods 221, and the spacing between each fixed connecting rod 221 is the same, evenly dividing the disk base 22 into six fan-shaped areas with an angle of 60 degrees. In the present invention, preferably, the connecting shaft body 21, the fixed connecting rod 221, and the disk base 22 are integrally arranged. The edge housing 24 is the above-mentioned annular edge, and the edge housing 24 is installed above the disk base 22. Its outer edge is a vertical ring, and its inner edge is a slope with a certain curvature. As shown in Figure 2, when the edge housing 24 is installed on the outside of the disk base 22, its outside completely covers the outside edge of the disk base 22, and its inside edge just fits with the outermost side of the fixed link 221 of the disk base 22.

[0029] The disk part 2 further includes an installation ring 23, and the installation ring 23 is used to assist the installation of the air-permeable component 1 on the inside of the disk part 2. When installing the air-permeable component 1, the disk base 22 is placed at the bottom, and then the air-permeable component 1 is placed above the disk base 22. At this time, the center point of the air-permeable component 1 coincides with the center point of the connecting shaft body 21, and the edge of the air-permeable component 1 slightly exceeds the outermost side of the fixed link 221 but does not exceed the edge of the disk base 22. After the air-permeable component 1 is set up, then the installation ring 23 is set above the air-permeable component 1. The outer edge perimeter of the installation ring 23 is the same as the outer edge perimeter of the disk base 22, and its inner edge also fits with the outermost side of the fixed link 221 of the disk base 22. After the installation ring 23 is set up, finally the edge housing 24 is sleeved above the installation ring 23. As a preference of the present invention, a number of screw holes are evenly provided on the installation ring 23, and the same number of screw holes are also provided at the positions corresponding to the outside of the disk base 22 on the edge housing 24. After the disk part 2 is arranged and set up, the edge housing 24, the installation ring 23, the air-permeable component 1, and the disk base 22 are fixed and locked with screws and nuts, and thus the installation of the disk part 2 including the air-permeable component 1 is completed. This installation structure not only ensures that the air-permeable component 1 can be stably installed on the inside of the disk part 2, but also facilitates the replacement of the air-permeable component 1.

[0030] As Figure 6 , as a preference of the present invention, the air-permeable component 1 is an air-permeable plate. A number of hollow air holes 11 are evenly distributed on the air-permeable plate. In the present invention, in order to make the gas flow upward evenly, the air holes 11 are arranged in a fan shape. The air-permeable component 1 can also be an air-permeable material such as a gauze net or a perforated plate, and in actual production, a gauze net, a perforated plate, etc. can also be used to replace the air-permeable plate.

[0031] As Figure 7 , the air blowing and flipping assembly 3 includes an upper shielding cover body 31 and a lower air blowing base 32. A number of air blowing holes 321 are provided on the air blowing base 32, and the air blowing holes 321 are used for blowing air in the vertical direction. The air blowing holes 321 can be strip-shaped, hole-shaped, and mesh-shaped. As a preference of the present invention, in order to better cooperate with the strip-shaped air holes 11 disclosed in the present invention, the air blowing holes 321 shown in the drawings are also strip-shaped. As Figure 3, when the blowing and flipping assembly 3 is arranged at the edge of the disk body part 2, the upper shielding cover body 31 thereof fits with the upper edge of the edge shell 24, and a certain distance is reserved between the lower blowing base 32 thereof and the lowermost end of the disk body base 22. The structure in which the shielding cover body 31 fits with the edge shell 24 can prevent the material from shaking and leaking out of the disk body part 2 from between the shielding cover body 31 and the edge shell 24 during flipping. A certain distance is reserved between the bottom surface of the blowing base 32 and the bottom surface of the disk body base 22. Specifically, a distance of 10 - 30 mm is reserved between the bottom surface of the blowing base 32 and the bottom surface of the disk body base 22. In the present invention, preferably, the distance between the bottom surface of the blowing base 32 and the bottom surface of the disk body base 22 is 20 mm. The structural setting in which a certain distance is reserved between the blowing base 32 and the disk body base 22 ensures that the gas can flow smoothly and evenly upward, preventing the material from flying out of the disk body structure due to excessive air flow or making it difficult for the material to flip due to too small air flow.

[0032] The specific working process of the present invention will be described below. The present invention needs to be used in cooperation with a manipulator and a vision detection mechanism. As Figure 8 , the present invention can be roughly divided into four areas, including a feeding position, a flipping position, a photographing position, and a grasping position. The flipping position is the area where the blowing and flipping assembly 3 is arranged, and the grasping position is arranged on the front side of the flipping position. In Figure 8 , the preset motor moves in the clockwise direction. At this time, the feeding position is arranged on the left side of the flipping position, and the photographing position is arranged on the right side of the flipping position. If the motor moves in the counterclockwise direction, the feeding position needs to be arranged on the right side of the flipping position, and at the same time, the photographing position needs to be arranged on the left side of the flipping position to ensure that the position sequence of the material moving on the flexible disk is the feeding position, the flipping position, the photographing position, and the grasping position in turn. The manipulator is arranged on the side of the grasping position, and the vision detection mechanism is arranged on the side of the photographing position. After the material is loaded, the disk body part 2 is driven by the motor to rotate as a whole, and first comes to the flipping position, that is, the area where the blowing and flipping assembly 3 is located. The blowing base 32 flips the material through blowing, and at the same time, the shielding cover body 31 prevents the material from being blown away during flipping. After the flipping is completed, the material continues to move to the photographing position with the rotation of the disk body part 2. The vision detection mechanism classifies and identifies the material by taking a photograph and sends the information of the target material to the manipulator. When the material runs to the grasping position, the manipulator can quickly grasp the target material. The ungrasped material will continue to rotate with the new material to the flipping position for flipping again, and this cycle repeats until all the materials are grasped and classified.

[0033] For the convenience of turning the materials and the overall partition setting of the flexible disk, the blowing and turning assembly 3 is integrally arranged in a fan shape. At the same time, in order to leave enough space for the photographing position and the grasping position, so that the vision detection mechanism has enough time to take pictures and identify, and the manipulator has enough time to grasp, the area occupied by the blowing and turning assembly 3 does not exceed one-third of the disk body part 2. As a structural preference of the present invention, the area occupied by the blowing and turning assembly 3 is one-sixth of the disk body part 2, that is, it occupies a fan-shaped area of 60 degrees.

[0034] Such as Figure 9 , Figure 9 This is the second embodiment of the present invention. Different from the air-permeable component 1 being set as an air-permeable plate in the first embodiment, in this embodiment, the air-permeable component 1 is set as a screen. A number of air-permeable holes 11 are distributed on the screen, and the materials can be stably carried. When the blowing base 32 blows air, the air flow passes through the air-permeable holes 11 of the screen and flows upward, driving the materials arranged on the screen to turn over. Compared with the air-permeable plate, the air-permeable holes 11 distributed on the screen are denser, and the total air flow that the blowing base 32 can pass through the air-permeable component 1 is larger when blowing air. Therefore, when dealing with a larger number of materials, after using the screen as the air-permeable component 1, the turning efficiency of the materials at the turning position is better.
