Technical Field

[0002] Flexible feeding is a flexible and efficient new feeding method, which can adapt to the changes and requirements in the production process, improve production efficiency and product quality, and reduce production costs.

[0003] Flexible feeding utilizes the interference principle of resonance and coherent waves, and through power devices such as voice coil motors, various vibration modes are generated in the material tray, so as to adjust the posture and position of the materials, making feeding more convenient.

[0010] Preferably, a plurality of groups of mesh holes are formed in the side wall of the bottom of the material tank; a slag collection box is fixedly connected to the bottom of the loading table; the slag collection box is arranged below the material tank.

[0024] In order to make the technical means, creative features, achieved purposes and functions implemented by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, a flexible feeding device according to an embodiment of the present utility model includes a feeding table 1; a material tank 2 is fixedly connected inside the feeding table 1; a conveyor belt 3 is installed on the top of the material tank 2; the conveyor belt 3 is inclined; a plurality of feeding plates 31 are fixedly connected to the middle of the conveyor belt 3; the feeding plates 31 are arranged in an array on the conveyor belt 3; a pair of vibrators 4 are fixedly connected to the top of the feeding table 1; a vibration conveying mechanism 5 is installed on the top of the vibrator 4; the vibration conveying mechanism 5 is arranged below the top end of the conveyor belt 3; a gripping robot 6 is fixedly connected to the top of the feeding table 1; the gripping robot 6 is arranged in the direction of the output end of the vibration conveying mechanism 5; a vision detection mechanism 9 is fixedly connected to the top of the feeding table 1; the vision detection mechanism 9 is sleeved on the vibration conveying mechanism 5; a detection baffle 10 is fixedly connected to the side wall of the vision detection mechanism 9; the detection baffle 10 is arranged above the vibration conveying mechanism 5. During operation, the workpiece to be fed is placed inside the material tank 2. By turning on the switch of the conveyor belt 3, the belt of the conveyor belt 3 rotates continuously. At this time, the feeding plates 31 on the conveyor belt 3 will move along with the movement of the belt, and then the workpieces stacked inside the material tank 2 are conveyed upward by the feeding plates 31. When the workpiece moves to the top of the conveyor belt 3, it will fall into the vibration conveying mechanism 5. Under the vibration of the vibrator 4, the workpiece moves forward horizontally and in a straight line inside the vibration conveying mechanism 5. When the workpiece moves to the position where the vision detection mechanism 9 is located, the skewed workpieces are blocked by the detection baffle 10 on the vision detection mechanism 9, and the workpieces with correct shape and position continue to be conveyed forward and are grabbed by the gripping robot 6 at the end of the vibration conveying mechanism 5, thus realizing the process of flexible feeding. When the workpiece moves past the vision detection mechanism 9, the vision detection mechanism 9 detects the characteristics of the workpiece. According to the detection result, the gripping robot 6 grabs the workpiece according to the characteristics of the workpiece, effectively ensuring that the gripping robot 6 can grab the workpiece in the same direction each time. Through the cooperation of the vision detection mechanism 9 and the detection baffle 10, the workpieces during the feeding process can always maintain the correct direction and position, reducing the problem that it is difficult to grab and place skewed workpieces, improving the stability and accuracy during the feeding process. At the same time, by detecting the characteristics of the workpiece through the vision detection mechanism 9, the gripping direction of the gripping robot 6 is kept consistent, facilitating the sorting of the workpieces and improving the feeding efficiency of the workpieces.

[0026] As Figures 1 to 4As shown in the figure, a lifting cylinder 7 is fixedly connected to the top of the loading table 1; the output end of the top of the lifting cylinder 7 is fixedly connected to a lifting support plate 71; the lifting cylinder 7 is arranged between the grasping robot 6 and the vibration conveying mechanism 5. During operation, after the workpiece is conveyed inside the vibration conveying mechanism 5, the workpiece can fall onto the lifting support plate 71. Under the action of the lifting cylinder 7, the lifting support plate 71 moves upward to lift the workpiece, and then the grasping robot 6 grasps the workpiece. By using the cooperation of the lifting cylinder 7 and the lifting support plate 71 to lift the workpiece, the feeding of the workpiece can be made more convenient, and the grasping effect of the grasping robot 6 can be better.

[0027] As Figures 1 to 5 shown in the figure, a skew workpiece conveyor belt 8 is installed inside the loading table 1; the skew workpiece conveyor belt 8 is arranged on the side of the conveyor belt 3; the skew workpiece conveyor belt 8 is inclined; the skew workpiece conveyor belt 8 is arranged on the loading table 1 near the detection baffle 10. During operation, by providing the skew workpiece conveyor belt 8 on the loading table 1, the skew workpieces can be blocked by the detection baffle 10 and thus fall above the skew workpiece conveyor belt 8. Under the conveyance of the skew workpiece conveyor belt 8, the skew workpieces fall into the material tank 2, and then are re-fed under the drive of the conveyor belt 3, making the feeding of the workpieces more automated and improving the convenience of the flexible feeding of the workpieces.

[0028] As Figures 1 to 3 shown in the figure, a plurality of sets of mesh holes 11 are opened on the bottom side wall of the material tank 2; a slag collection box 12 is fixedly connected to the bottom of the loading table 1; the slag collection box 12 is arranged below the material tank 2. During operation, some metal slag generated after the production of the workpiece often remains on the surface. When a pile of workpieces are mixed inside the material tank 2, the metal slag on the surface of the workpiece will collide and fall to the bottom of the material tank 2 for accumulation. At this time, by providing the mesh holes 11 at the bottom of the material tank 2 and arranging the slag collection box 12 below the material tank 2, the debris falling from the workpiece can fall into the slag collection box 12 through the mesh holes 11. The slag collection box 12 is used to recycle and clean the slag, reducing the possibility of wear on the surface of the workpiece caused by the accumulation of slag inside the material tank 2 and improving the production quality of the workpiece.

[0029] As Figure 3 and Figure 6As shown in the figure, a spring damper 13 is fixedly connected to the side wall of the material chute 2; a buffer plate 14 is fixedly connected to the end of the spring damper 13; the buffer plate 14 is inclined; the buffer plate 14 is arranged below the skewed workpiece conveyor belt 8. During operation, by providing the buffer plate 14 on the material chute 2, when the workpiece falls from the skewed workpiece conveyor belt 8 into the interior of the material chute 2, the workpiece will first fall onto the buffer plate 14 and then slide into the interior of the material chute 2. Under the buffering effect of the spring damper 13, the potential energy when the workpiece falls is reduced, so that when the workpiece falls into the interior of the material chute 2, the mutual collision between workpieces is reduced, and the safety between workpieces is improved.

[0030] As Figure 3 and Figure 6 As shown in the figure, a flexible pad 15 is fixedly connected to the side wall of the buffer plate 14; the flexible pad 15 is arranged on the side wall of the buffer plate 14 close to the skewed workpiece conveyor belt 8. During operation, by providing the flexible pad 15 on the buffer plate 14, when the workpiece contacts the buffer plate 14, the wear on the surface of the workpiece is reduced, and the protection effect on the workpiece is improved.

[0031] Working principle: Place the workpiece to be loaded into the interior of the material chute 2. By turning on the switch of the conveyor belt 3, the belt of the conveyor belt 3 rotates continuously. At this time, the loading plate 31 located on the conveyor belt 3 will move along with the movement of the belt, and then the workpieces stacked in the interior of the material chute 2 are conveyed upward by the loading plate 31. When the workpiece moves to the top of the conveyor belt 3, it will fall into the vibration conveying mechanism 5. Under the vibration action of the vibrator 4, the workpiece moves forward horizontally and in a straight line inside the vibration conveying mechanism 5. When the workpiece moves to the position where the vision detection mechanism 9 is located, the skewed workpieces are blocked by the detection baffle 10 on the vision detection mechanism 9, and the workpieces with correct shape and position continue to be conveyed forward and are grabbed by the robotic arm 6 at the end of the vibration conveying mechanism 5, thereby realizing the process of flexible loading. When the workpiece moves past the vision detection mechanism 9, the vision detection mechanism 9 detects the characteristics of the workpiece. According to the detection result, the robotic arm 6 grabs the workpiece according to the workpiece characteristics, effectively ensuring that the robotic arm 6 can grab the workpiece in the same direction each time. Through the cooperation of the vision detection mechanism 9 and the detection baffle 10, the workpieces during the loading process can always maintain the correct direction and position, reducing the problem that skewed workpieces are difficult to grab and place, improving the stability and accuracy during the loading process. At the same time, by detecting the workpiece characteristics through the vision detection mechanism 9, the grabbing direction of the robotic arm 6 is kept consistent, facilitating the sorting of workpieces and improving the efficiency of workpiece loading.

[0032] After the workpiece is conveyed inside the vibration conveying mechanism 5, the workpiece can fall onto the lifting pallet 71. Under the action of the lifting cylinder 7, the lifting pallet 71 moves upward to lift the workpiece. Then, the grasping robot 6 grasps the workpiece. By using the cooperation of the lifting cylinder 7 and the lifting pallet 71 to lift the workpiece, the feeding of the workpiece can be made more convenient, and the grasping effect of the grasping robot 6 can be better.

[0033] By providing a skew workpiece conveyor belt 8 on the loading table 1, skew workpieces can be blocked by the detection baffle 10 and thus fall above the skew workpiece conveyor belt 8. Under the conveyance of the skew workpiece conveyor belt 8, the skew workpieces fall into the material tank 2, and then are re-fed under the drive of the conveyor belt 3, making the feeding of the workpieces more automated and improving the convenience of flexible feeding of the workpieces.

[0034] Metal slag generated after the production of the workpiece often remains on the surface. When a pile of workpieces are mixed inside the material tank 2, the metal slag on the surface of the workpiece will collide and fall to the bottom of the material tank 2 for accumulation. At this time, by providing a mesh hole 11 at the bottom of the material tank 2 and arranging a slag collection box 12 below the material tank 2, the debris falling from the workpiece can fall into the slag collection box 12 through the mesh hole 11. The slag collection box 12 recovers and cleans the slag, reducing the possibility of the surface of the workpiece being worn due to the accumulation of slag inside the material tank 2 and improving the production quality of the workpiece.

[0035] By providing a buffer plate 14 on the material tank 2, when the workpiece falls from the skew workpiece conveyor belt 8 into the material tank 2, the workpiece will first fall onto the buffer plate 14 and then slide into the material tank 2. Under the buffering action of the spring damper 13, the potential energy of the workpiece when falling is reduced, and when the workpiece falls into the material tank 2, the mutual collision between the workpieces is reduced, improving the safety between the workpieces.

[0036] By providing a flexible pad 15 on the buffer plate 14, when the workpiece contacts the buffer plate 14, the wear on the surface of the workpiece is reduced, improving the protection effect on the workpiece.
