Description

Technical Field

[0001] The present invention relates to the technical field of material sorting equipment, and in particular to an air-blowing flexible tray. Background Art

[0002] Robots and visual recognition are increasingly used in industrial production. During the material feeding and picking process, robots and visual recognition modules are often used to perform intelligent picking operations.

[0003] For some small, sheet-like products with front and back sides, strict requirements exist regarding their placement during assembly or processing, such as whether they must face up or down. For automated loading of these products, as previously mentioned in the applicant's invention patent application, publication number CN113998398A, a flexible disc is typically used to vibrate, breaking up and flipping the material within. A vision system then uses camera images to screen and calculate the location of qualified products. Finally, a robotic arm grabs and moves the material for loading.

[0004] However, when the current flexible disk vibrates, the entire flexible disk often vibrates, so when the robot grasps the material, in order to prevent the grasping accuracy of the material in the picking process from being affected, the flexible disk needs to stop vibrating, which slows down the working efficiency of the material identification and grasping system. Summary of the Invention

[0005] In order to solve the problems of traditional vibrating flexible discs, the present invention proposes an air-blowing flexible disc, which can break up and flip the materials without affecting the identification and grasping of other parts of the materials, thereby speeding up the working efficiency of the material identification and grasping system.

[0015] The disc base comprises a plurality of fixed connecting rods, the connecting shaft is arranged at the center of the disc base and is fixedly connected with the disc base through the fixed connecting rods.

[0016] The disc part further comprises a mounting ring, and the mounting ring, the disc base and the edge shell are all provided with uniformly distributed screw holes, and the air permeable component is clamped and fixed above the disc base by screwing.

[0017] The fixed connecting rods are six in total, are uniformly distributed in the circumferential direction and divide the disc base into six fan-shaped regions of the same size. When the blowing and overturning assembly is arranged at the edge of the disc part, the area covered by the blowing and overturning assembly on the disc part is one sixth to one third of the total area of the disc part, that is, one to two fan-shaped regions.

[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 7 , Figures 1 to 7 This is a first embodiment of an air-blown flexible tray. It comprises a breathable component 1, a tray body 2, and an air-blowing flip assembly 3. The tray body 2 is generally circular, with an annular edge at its outermost edge and a connecting shaft 21 below it for connection to an external motor. The breathable component 1 is positioned within the annular edge of the tray body 2, while the air-blowing flip assembly 3 is positioned close to the annular edge of the tray body 2.

[0034] like Figure 4 、 Figure 5, the disk body part 2 includes a connecting shaft 21, a disk base 22 and an edge shell 24. The connecting shaft 21 is arranged in a vertical direction, and the connecting shaft 21 is connected to the disk base 22 through a fixed connecting rod 221. There are six fixed connecting rods 221 in total, and the spacing between each fixed connecting rod 221 is the same, which evenly divides the disk base 22 into six fan-shaped areas with an angle of 60 degrees. In the present invention, it is preferred that the connecting shaft 21, the fixed connecting rod 221 and the disk base 22 are integrated. The edge shell 24 is the annular edge mentioned above, and the edge shell 24 is installed above the disk base 22, and its outer edge is a vertical ring, and its inner edge is a slope with a certain curvature. As Figure 2 When the edge shell 24 is installed on the outside of the disk base 22, its outer side completely covers the outer edge of the disk base 22, and its inner edge just fits with the outermost side of the fixed connecting rod 221 of the disk base 22.

[0035] The disc portion 2 also includes a mounting ring 23, which assists in mounting the ventilating component 1 within the disc portion 2. When mounting the ventilating component 1, place the disc base 22 at the bottom, then place the ventilating component 1 above the disc base 22. At this point, the center of the ventilating component 1 coincides with the center of the connecting shaft 21, and the edge of the ventilating component 1 slightly extends beyond the outermost edge of the fixing rod 221 but does not extend beyond the edge of the disc base 22. After the ventilating component 1 is installed, the mounting ring 23 is then positioned above the ventilating component 1. The outer edge of the mounting ring 23 has the same circumference as the outer edge of the disc base 22, and its inner edge also aligns with the outermost edge of the fixing rod 221 of the disc base 22. After the mounting ring 23 is installed, the edge housing 24 is finally placed over the mounting ring 23. Preferably, the mounting ring 23 is evenly spaced with a plurality of screw holes, and the edge housing 24 has an equal number of screw holes at positions corresponding to the outer sides of the disc base 22. After the tray body 2 is arranged and set, screws and nuts are used to securely lock the edge shell 24, mounting ring 23, ventilating component 1, and tray base 22. This completes the installation of the tray body 2 including the ventilating component 1. This installation structure ensures that the ventilating component 1 can be stably installed inside the tray body 2 and facilitates replacement of the ventilating component 1.

[0036] like Figure 6 As a preferred embodiment of the present invention, the ventilation component 1 is a ventilation plate. The ventilation plate is evenly distributed with a plurality of hollow ventilation holes 11. In the present invention, the ventilation holes 11 are arranged in a fan-shaped pattern to ensure uniform upward flow of gas. The ventilation component 1 can also be made of a breathable material such as gauze or perforated plate. In actual production, gauze, perforated plate, etc. can also be used instead of a ventilation plate.

[0037] likeFigure 7 The air blowing and overturning assembly 3 comprises an upper half shielding cover 31 and a lower half air blowing base 32, and a plurality of air blowing holes 321 are arranged on the air blowing base 32 for air blowing in the vertical direction. The air blowing holes 321 can be strip-shaped, hole-shaped or net-shaped, and are preferably strip-shaped in the drawings to better cooperate with the strip-shaped air permeable holes 11 disclosed in the present application. Figure 3 When the air blowing and overturning assembly 3 is arranged at the edge of the disc body part 2, the upper half shielding cover 31 of the air blowing and overturning assembly 3 is attached to the upper edge of the edge shell 24, and the lower half air blowing base 32 is kept a certain distance from the lowermost end of the disc body base 22. The structure that the shielding cover 31 is attached to the edge shell 24 can prevent the material from being shaken off the disc body part 2 during overturning. The air blowing base 32 is kept a certain distance from the bottom surface of the disc body base 22, and specifically, the distance between the air blowing base 32 and the bottom surface of the disc body base 22 is 10-30 mm. In the present application, the distance between the air blowing base 32 and the bottom surface of the disc body base 22 is preferably 20 mm. The structure that the air blowing base 32 is kept a certain distance from the disc body base 22 ensures that the gas can flow smoothly and uniformly upward, preventing the gas flow from being too large to cause the material to fly out of the disc structure, or the gas flow from being too small to cause the material to overturn.

[0038] The specific working process of the present application will be described below. The present application needs to be used together with a mechanical hand and a visual detection mechanism. As shown in FIG. 4, the working process of the present application is as follows. Figure 8 The present application can be roughly divided into four areas, including a feeding position, an overturning position, a photographing position and a grabbing position. The overturning position is the area where the air blowing and overturning assembly 3 is arranged, and the grabbing position is arranged in front of the overturning position. Figure 8In the case of the preset motor moving in the clockwise direction, the feeding position is set to the left side of the turnover position, and the photographing position is set to the right side of the turnover position. If the motor moves in the counterclockwise direction, the feeding position needs to be set to the right side of the turnover position, and the photographing position needs to be set to the left side of the turnover position, so as to ensure that the position sequence of the material moving on the flexible disc is feeding position, turnover position, photographing position, and grabbing position in turn. The manipulator is arranged on the side of the grabbing position, and the visual detection mechanism is arranged on the side of the photographing position. After the material is loaded, the disc body part 2 is driven to rotate as a whole by the motor, and first comes to the area where the blowing turnover assembly 3 is located. The blowing base 32 blows the material to turn over, and the shielding cover 31 prevents the material from being blown away during the turning over. After the turning over is completed, the material continues to rotate with the disc body part 2 to the photographing position. The visual detection mechanism classifies and identifies the material through photographing, and sends the information of the target material to the manipulator. When the material rotates to the grabbing position, the manipulator can quickly grab the target material. The material that is not grabbed will continue to rotate with the new material to the turnover position for re-turning, and the cycle continues until all the materials are classified and grabbed.

[0039] In order to facilitate the turnover of the material and the overall partitioning of the flexible disc, the blowing turnover assembly 3 is arranged in a fan shape. At the same time, in order to leave enough space for the photographing position and the grabbing position, so that the visual detection mechanism has enough time to take pictures and identify, and the manipulator has enough time to grab, the area occupied by the blowing turnover assembly 3 is not more than one third of the area of the disc body part 2. As a preferred structure of the present application, the area occupied by the blowing turnover assembly 3 is one sixth of the area of the disc body part 2, that is, it occupies a 60-degree fan area.

[0040] As Figure 9 , Figure 9 is a second embodiment of the present application. Unlike the first embodiment in which the air-permeable part 1 is provided as an air-permeable plate, the air-permeable part 1 in the present embodiment is provided as a gauze screen. The gauze screen is provided with a plurality of air-permeable holes 11 and can stably carry the material. When the blowing base 32 blows, the airflow flows upward through the air-permeable holes 11 of the gauze screen and drives the material arranged on the gauze screen to turn over. Compared with the air-permeable plate, the air-permeable holes 11 distributed on the gauze screen are more dense, and the total amount of airflow passing through the air-permeable part 1 when the blowing base 32 blows is larger. Thus, when there are more materials, the turnover efficiency of the material at the turnover position is better when the gauze screen is used as the air-permeable part 1.
