Description

Technical Field

[0001] The present application relates to a feeding device, and in particular to an automatic feeding vibration mechanism based on industrial vision. Background Art

[0002] A vibrating bowl is a mechanism that drives materials to move through vibration. There is an impulse electromagnet under the hopper of the vibrating bowl, which can make the hopper vibrate in the vertical direction. The inclined spring plate drives the hopper to perform a torsional vibration around its vertical axis. As a result, the parts in the hopper are vibrated and rise along the spiral track.

[0003] Generally, a screening mechanism is provided at the discharge port of the vibrating bowl. The screening mechanism is generally divided into two types: visual screening and mechanical screening. Among them, visual screening is based on a high-resolution camera and image processing technology, and the screening is carried out by comparing the picture features. The materials that do not conform to the placement rules will be removed from the discharge port and returned to the hopper. The disadvantage of screening in this way is that for some specific materials, when they fall from the discharge port into the hopper, they will collide and cause deformation or damage.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] In addition, in the application, the terms "first", "second" and other similar terms do not intend to imply any order, quantity and importance, but are only used to distinguish different elements. The terms "upper", "lower", "left", "right" and other similar terms are only the positional relationships in the drawings.

[0028] Such as Figure 1As shown in the figure, an automatic feeding vibration mechanism based on industrial vision provided by an embodiment of the present application includes an external support plate 1, a vibrating disk 2, a flipping mechanism 3, a steering mechanism 4, a discharge guide rail 5, a camera A 7, and a camera B 8. Among them, the vibrating disk 2 is installed inside the external support plate 1, and the flipping mechanism 3, the steering mechanism 4, the camera A 7, and the camera B 8 are all installed on the side wall of the external support plate 1. With such a setting, the vibration of the vibrating disk 2 can be prevented from damaging the flipping mechanism 3, the steering mechanism 4, the camera A 7, and the camera B 8. The discharge guide rail 5 is fixedly connected to the outer side wall of the vibrating disk 2 through a support rod 6. The flipping mechanism 3 is used to drive the material to be flipped on the vertical plane, and the steering mechanism 4 is used to drive the material to rotate on the horizontal plane. From the advancing direction of the material, the camera A 7, the flipping mechanism 3, and the camera B 8 are arranged in sequence, and the steering mechanism 4 is located on one side of the camera B 8.

[0029] As Figure 2 shown, when the vibrating disk 2 is running, the material passes through the camera A 7, the flipping mechanism 3, the camera B 8, and the steering mechanism 4 in sequence, and finally enters the discharge guide rail 5. When the material passes under the camera A 7, the camera A 7 takes a picture of the material, and based on the visual detection system, the posture of the material is judged, and the operation plan of the flipping mechanism 3 is generated according to the posture of the material. Similarly, the operation plan of the steering mechanism 4 is generated based on the picture taken by the camera B 8.

[0030] In this way, it can be realized that in the conveying track, according to the results detected by the camera A 7 and the camera B 8, the posture of the material is adjusted in real time.

[0031] As Figure 3 shown, in an embodiment of the present application, the flipping mechanism 3 includes a wheel disk 31, a grooved wheel 32, a dial rod 33, and a pulley 34. Among them, one end of the wheel disk 31 is provided with a pulley 34, and the other end of the wheel disk 31 is provided with a section of tube. The wheel disk 31 can be installed on the shell of the flipping mechanism 3 through the tube. An accommodation groove 35 is provided inside the wheel disk 31, and the accommodation groove 35 can only accommodate a single material. The middle of the dial rod 33 is connected to the transmission shaft, and two pulleys 34 are symmetrically installed on both sides of the dial rod 33. The pulley 34 can cooperate with the grooved wheel 32. In this way, when the dial rod 33 rotates one circle, the wheel disk 31 can rotate half a circle, and when the dial rod 33 rotates half a circle, the wheel disk 31 can rotate 90 degrees.

[0032] For some specific materials, the types of their placement postures in the conveying track are limited. For example, for square materials, there are only four postures on a vertical plane, and for flat materials, there are only two postures on a vertical plane. In actual applications, flat materials and square materials are mostly used. Therefore, in this embodiment, exemplarily, the number of grooves in the grooved wheel 32 is set to four to meet the requirement of "flipping the material 90 degrees or 180 degrees".

[0033] As Figure 3 shown, in an embodiment of the present application, the flipping mechanism 3 further includes a baffle 36. The baffle 36 is driven by a linear transmission mechanism, such as a cylinder drive. The baffle 36 can move radially along the grooved wheel 32. Since the material has a tendency to move towards 5 when it is inside the grooved wheel 32, when the grooved wheel 32 is flipped, the accommodating groove 35 can be blocked by moving the baffle 36, thereby preventing the material from moving radially along the grooved wheel 32 during the flipping process.

[0034] As Figure 4 shown, in an embodiment of the present application, the steering mechanism 4 includes a cylinder 41, a support plate 42, a base 43, a suction cup module 44, and a power source 45. The cylinder 41 is installed on the external support plate 1. The support plate 42 is fixedly connected to the telescopic rod of the cylinder 41, and the support plate 42 is fixedly connected to the base 43. The suction cup module 44 is installed on the base 43. The power source 45 is used to drive the suction cup module 44 to rotate. In this way, when it is necessary to horizontally flip the material, the cylinder 41 drives the suction cup module 44 to move above the material, and then the suction cup module 44 adsorbs the material, and the power source 45 is used to drive the material to rotate.

[0035] As Figure 5 shown, in an embodiment of the present application, a ratchet 49 is installed inside the base 43, a pull rod 46 is installed inside the power source 45, the power source 45 can drive the pull rod 46 to move linearly, a plurality of rotatable ratchet teeth 50 are installed on the pull rod 46, and a spring 51 is provided on one side of each ratchet tooth 50. The two ends of the spring 51 are respectively connected to the pull rod 46 and the ratchet tooth 50; the ratchet 49 is provided with four teeth. In this way, every time the ratchet tooth 50 cooperates with the ratchet 49 and drives the ratchet 49 to rotate, the ratchet 49 rotates 90 degrees each time; at the same time, a transmission wheel B48 is provided at one end of the ratchet 49, the transmission wheel B48 rotates synchronously with the ratchet 49, and the suction cup module 44 is fixedly connected to a transmission wheel A47. The transmission wheel A47 and the transmission wheel B48 are connected by a belt. In this way, it can be realized that the suction cup module 44 is driven to rotate by the horizontal movement of the pull rod 46, and the suction cup module 44 rotates only 90 degrees each time.

[0036] As Figure 6As shown, in an embodiment of the present application, the suction cup module 44 includes a movable tube 441, a suction cup 442, a spacer 443, an interface 444, and a nut 445. The movable tube 441 is located below the interface 444. A spacer 443 is provided between the movable tube 441 and the interface 444. A suction cup 442 is installed at the bottom of the movable tube 441. The nut 445 is sleeved on the interface 444, and the nut 445 is fixedly connected to the base 43. Limiting bosses are provided on both the interface 444 and the movable tube 441. The limiting bosses cooperate with the nut 445 and the base 43 to limit the axial movement of the interface 444 and the movable tube 441.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
