Description

Technical Field

[0001] The present invention relates to the field of electronic component identification, and in particular to a visual sorting device for electronic components. Background Art

[0002] There are many kinds of electronic components. In the prior art, they are usually sorted by the naked eye, and the sorting effect is low. When disassembling the assembled equipment, it is not easy to quickly and accurately complete the classification of various parts. At present, some researchers also use camera photography and image recognition to sort components, that is, use a conveyor belt to put multiple components one by one under the camera for photography, and then use image recognition to sort the components. However, when the above technology is used, due to the small size of some electronic components and their own shape, they are easy to roll. Therefore, when they are put, they are easy to be misaligned with the camera shooting position, and the problem of exceeding the camera capture range may occur. When it is necessary to adjust the camera field of view to meet the capture range of a wider field, the shooting effect will be poor and difficult to identify. Or, a better camera can be used to obtain higher-definition pictures, but this will increase the cost. Therefore, the above-mentioned improved technical means have defects.

DETAILED DESCRIPTION

[0026] Reference Figure 1-8 A visual sorting device for electronic components comprises a bottom box 1 of a cylindrical structure, the top of the bottom box 1 is open, a fixed platform 6 is arranged in the bottom box 1, a turntable 10 is connected to the top of the fixed platform 6 and a steering gear is connected through the turntable 10, a plurality of layered plates 101 are arranged in a ring shape on the side circular surface of the fixed platform 6, every two adjacent layered plates 101, the fixed platform 6 and the inner wall of the bottom box 1 form a storage space 102, each storage space 102 can hold an electronic component, each storage space 102 is connected to an open storage box 103, the bottom of the storage box 103 passes through the inner bottom wall of the bottom box 1 and is flush with the outer bottom of the bottom box 1, so that each storage box 103 can be separated independently.

[0027] Two arms 2 are symmetrically arranged on the top wall of the bottom box 1, and an extension portion 104 is arranged on the top of the bottom box 1. The two arms 2 are fixed to the extension portion 104 through angle seats and bolts; the two arms 2 are commonly fixedly connected with a cross beam 3, and an installation box 4 is arranged in the middle of the cross beam 3. A camera 5 is fixedly arranged at the bottom of the installation box 4, and the camera 5 is used for visual identification and sorting of electronic components.

[0028] A sorting assembly 7 is provided in the fixed platform 6. The sorting assembly 7 includes two fixed plates 71. The two fixed plates 71 are symmetrically arranged on the top of the turntable 10. The tops of the two fixed plates 71 are commonly connected with a mounting frame 72. The mounting frame 72 is arranged in an inverted "I"-shaped structure. A sorting bucket 73 is connected to the top of the mounting frame 72. The sorting bucket 73 and the mounting frame 72 are commonly connected with a swing assembly 8 that allows the sorting bucket 73 to tilt and swing. The sorting bucket 73 is located above the bottom box 1, so that when the sorting bucket 73 is tilted by the swing assembly 8, the electronic components therein will fall into the corresponding storage box 103 for sorting and storage;

[0029] The swing assembly 8 includes a transmission gear 1 81 and a transmission gear 2 82. The number of teeth of the transmission gear 2 82 is greater than that of the transmission gear 1 81. The transmission gear 1 81 is coaxially connected with a sleeve rod 83. The sleeve rod 83 is internally connected with a rotating rod 84 for cooperation and rotation. The two ends of the rotating rod 84 are respectively fixedly connected to the two side walls of the mounting frame 72. The sleeve rod 83 passes through the two fixed plates 71 respectively and is rotatably connected to the two fixed plates 71. A hydraulic cylinder 85 is arranged inside the fixed platform 6. The output shaft of the hydraulic cylinder 85 passes through the turntable 10 and is connected with a pull-down assembly 11. The pull-down assembly 11 is close to the opening side of the sorting bucket 73 and pulls the sorting bucket 73 to swing and unload by magnetic attraction. The pull-down assembly 11 is connected to the positioning assembly 9. The transmission gear 2 82 is rotatably connected to the fixed plate 71 through a transmission shaft 86.

[0030] The interior of the sorting bucket 73 is connected with a positioning assembly 9 so as to position the electronic components directly below the camera 5. The positioning assembly 9 includes two groups of symmetrically arranged centering parts 91. Each group of centering parts 91 includes a middle plate 911 and two side plates 912. The two side plates 912 are rotatably connected to the middle plate 911 through a rotating shaft 913. The rotation limit of each side plate 912 and the middle plate 911 is set to -15° to 45°. A torsion spring is set at the rotation connection between the side plate 912 and the middle plate 911. The end of each side plate 912 away from the middle plate 911 is set to a magnet structure and is magnetically attracted to the inner wall of the sorting bucket 73. In this way, when the middle plate moves, in the initial stage of the movement, the two side plates 912 will be close to the inner wall of the sorting bucket 73 under the action of magnetic attraction. Figure 8 As shown in a, the angle between the side plate 912 and the middle plate 911 changes to a negative angle. When the middle plate 911 continues to move, since there is a rotation limit between the side plate 912 and the middle plate 911, the side plate 912 will gradually separate from the material distribution hopper 73, and after a certain distance from the material distribution hopper 73, it will separate from the state of being magnetically attracted by the material distribution hopper 73. At this time, under the action of the torsion spring energy storage, multiple side plates 912 simultaneously rotate in the opposite direction to one Figure 8 b state for an instant, and then under the pulling force of the torsion spring, it returns to the state where the side plate 912 and the middle plate 911 are flush, thereby positioning the components on the sorting bucket 73 just below the middle camera 5 for easy image recognition, and each middle plate 911 is connected to a square extension rod 92, two square extension rods 92 pass through the side walls of the sorting bucket 73 and are connected to a sleeve 93 on the outer part, one end of the extension rod 92 located in the sleeve 93 is connected to a threaded block 95 through a spring 94, and the threaded block 95 is threadedly connected to the inner wall of the sleeve 93, so that the internal threaded block 95 can be driven to move by the rotation of the sleeve 93, thereby realizing the function of moving the middle plate 911.

[0031] The pull-down assembly 11 includes a rack 111 meshed with the transmission gear 2 82, the top of the rack 111 is connected to a connecting plate 112, and a magnetic suction cup 113 is fixedly provided on the side of the connecting plate 112 away from the rack 111, and the magnetic suction cup 113 is magnetically connected to the outer bottom of the sorting bucket 73 when it contacts the sorting bucket 73. The advantage of this is that the magnetic suction cup 113 can be driven to approach the sorting bucket 73 by the movement of the rack 111, so that when the rack 11 moves downward, the sorting bucket 73 can be driven to swing by the magnetic suction cup 113, so that the components on the sorting bucket 73 can be tilted and slid into the corresponding storage box 103, and the two ends of the sleeve rod 83 are respectively connected to a synchronous wheel 114, and each synchronous wheel 114 is connected to a synchronous wheel 2 116 through a synchronous belt 115, and the synchronous wheel 2 116 is coaxially fixed on the sleeve 93.

[0032] When the present invention is in use, first, the component enters the sorting bucket 73 through the conveying assembly (such as a conveyor belt), and then the hydraulic cylinder 85 drives the rack 111 to mesh with the transmission gear 2 82, so that the transmission gear 2 82 drives the transmission gear 1 81 to accelerate the rotation, and drives the sleeve 93 to rotate through the synchronous wheel structure, and the rotation of the sleeve 93 drives the extension rod 92 inside it to slide, thereby driving the centering part 91 from Figure 8 The state of a is transformed into Figure 8 b state, which can effectively position the electronic components put into the sorting bucket 73 to the right below the middle camera 5, and then the camera 5 starts to work, distinguishes the types of electronic components through image recognition, and then transmits the information to the steering gear, and rotates to the top of the corresponding storage box 103. At this time, the hydraulic cylinder 85 is controlled to shrink, and then the downward movement of the magnetic suction cup 113 will drive the front part of the sorting bucket 73 to swing downward under the magnetic attraction, and then the continued downward movement of the magnetic suction cup 113 will cause the rack 111 and the transmission gear 2 82 to rotate in the opposite direction, thereby driving the multiple centering parts 91 to return to the initial position, and when the magnetic suction cup 113 is far away from the sorting bucket 73, it will lose the state of mutual magnetic attraction with the sorting bucket 73. At the same time, the rear side of the sorting bucket 73 is connected to the top of the turntable 10 through a spring (not shown in the figure), so that the tilted sorting bucket 73 will return to the initial horizontal state under the action of elastic force after losing the magnetic attraction, which is convenient for the dumping and subsequent use of the electronic components.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
