Description
Technical Field
The invention relates to the technical field of material sorting, in particular to a material sorting device based on a visual detection technology.
Background
For some tiny components, the prior art sorts them by a visual inspection robot, for example, a visual intelligent inspection robot disclosed by my company, patent No. 201820375491.1, in which: the detection device comprises a cabinet and a detection device arranged in the cabinet, wherein the detection device comprises a bottom plate, a rotary glass disc is arranged in the center of the bottom plate through a rotating shaft, an entire feeding mechanism, a sensor, a visual detection camera and a discharging mechanism are sequentially arranged on the bottom plate, which is positioned on the periphery of the rotary glass disc, around the rotary glass disc in a clockwise direction, a lens of a fifth visual detection camera extends into the bottom surface of the rotary glass disc and is vertically arranged upwards, a reflector is arranged on one side of the fifth visual detection camera through an adjusting bracket and is positioned above the lens and the rotary glass disc; through setting up rotatory glass dish as the feed table to use the vision detection camera of the rotatory glass dish bottom surface of corresponding dive, make this robot can detect the bottom surface of small part, improve the integrality and the accuracy nature that detect greatly.
The working principle of the technical scheme is as follows: through visual inspection (including bottom surface) of each angle, qualified parts are sent into one drawer of unloading mechanism, and unqualified parts are sent into the other drawer of unloading mechanism.
The technical scheme has the following disadvantages: both the qualified parts and the unqualified parts are fed into the blanking mechanism in the last step of the process, that is, the robot must accurately identify each part in the blanking mechanism, and accurately feed them into their respective drawers (using two air guns to blow parts, certified products into the certified drawer, and non-certified products into the non-certified drawer), easily understandable, with a distance from the last camera to the blanking mechanism, because certain mechanical vibration is inevitably generated during the operation of the equipment, the positions and postures of all parts on the rotating glass disc are possible to slightly change, the robot usually judges the real-time positions of the parts through the rotating angle of the rotating glass disc, so the vibration can cause certain misleading to the blanking of the final stage of the robot, and the robot can blow the parts into the same drawer by mistake.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a visual detection sorting device for removing unqualified parts in priority.
The technical scheme of the invention is as follows:
the utility model provides a material sorting device based on visual detection technique which characterized in that: the device comprises a bottom plate, wherein a rotary glass disc is arranged in the center of the bottom plate through a rotating shaft, a guide mechanism, a first side visual inspection camera, a bottom visual inspection camera, a second side visual inspection camera and an NG product removing mechanism are sequentially arranged on the bottom plate at the position, located on the periphery of the rotary glass disc, around the rotary glass disc in a clockwise direction, a lens of the bottom visual inspection camera extends into the bottom surface of the rotary glass disc and is vertically arranged upwards, the NG product removing mechanism comprises a bottom frame, a first connecting rod, a second connecting rod, a third connecting rod, a fixed block and an air spray gun, the bottom frame is arranged on the bottom plate, one end of the first connecting rod is arranged on the bottom frame, the second connecting rod is vertically arranged on the first connecting rod, the tail end of the second connecting rod is vertically connected with the third connecting rod, the tail end of the third, the gun head of the air spray gun faces to the lower part of the first connecting rod.
Further, lead positive mechanism and include base, first installation arm, first lead positive piece, second installation arm and second and lead positive piece, the base top surface is installed respectively and is slightly become the first installation arm and the second installation arm of L type, and first installation arm front end is installed first through the bolt and is led positive piece, and second installation arm front end is installed the second through the bolt and is led positive piece, and first leading positive piece and second lead positive piece and fold into the V style of calligraphy but reserve and have the crack that can supply spare part to pass through, and its benefit can be with just following rotatory glass dish pivoted spare part pendulum, does benefit to subsequent shooting.
Further, first installation arm and second installation arm front end all are provided with the mounting groove, and its benefit is that the bolt that is used for installing the guide piece can adjust the position as required, is convenient for guide the position adjustment of piece.
Further, the equidistance is provided with a plurality of mounting holes on the head rod, be provided with the activity groove on the second connecting rod, the second connecting rod passes the activity groove through the bolt and the mounting hole is connected with the head rod, and the size cooperation bolt setting of mounting hole, the width in activity groove is greater than the maximum diameter of bolt screw portion. The function of the device is that the position of the air spray gun can be adjusted, so that the gun head can be aligned with parts on the rotating glass plate.
In some embodiments, the base of the guiding mechanism is provided with a lifting adjusting mechanism and a rotating adjusting mechanism for adjusting the height and the angle of the guiding block.
In some embodiments, an optical fiber sensor is disposed on the bottom plate and between the guiding mechanism and the first side visual inspection camera, and is used for sensing whether the front end face and the rear end face of the material conveyed by the rotating glass disc are correct.
In some embodiments, an NG product recovery hopper is arranged on the bottom plate and in front of the gun head, and is used for recovering materials blown out by the air spray gun.
The working principle of the invention is as follows:
leading through leading just mechanism earlier, then respectively through the detection of first side visual inspection camera, bottom surface visual inspection camera, second side visual inspection camera, detect qualified then collect through artifical or other equipment, detect unqualifiedly and use the air spray gun to blow out rotatory glass dish scope with it for the certified products must be received to unloading mechanism department. Because the unqualified parts are very few after all, the air blowing time of the air spray gun can be controlled by a robot or manually. For example, the part passes through the second side visual inspection camera and then the rotating glass disc rotates by 30 degrees to reach the air spray gun, if manual control is performed, the air spray gun can be started after the part is found to be unqualified through visual inspection and the part passes through the second side visual inspection camera and then the rotating glass disc rotates by 30 degrees, and therefore the product is accurately removed. Obviously, according to the existing visual inspection technology, the process is not difficult to realize by using an information automation technology, so that the process can also be realized by a robot. It is easy to understand that the normal parts before or after the unqualified parts are blown off together due to mechanical shaking, but the rotation angle is not required to be calculated during final blanking, a special blanking robot is not required for blanking, and hundreds of qualified parts can be collected even if manual blanking is adopted, so that the quality of finished products is ensured.
The invention has the beneficial effects that: the original mode of finding qualified products or distinguishing the qualified products and the unqualified products simultaneously through visual detection is abandoned, and the mode of only processing the unqualified products is adopted, so that the times of air blowing are reduced, and energy and air sources can be saved.
