[0002] In the field of mechanical automation, through the design of relevant mechanical structures and the cooperation of relevant mechanical structures, some automated actions can be performed to achieve corresponding functions. Among them, in automated mechanical equipment, it is a practical requirement to sort different types of materials transmitted through a tray, and the sorting of materials involves the judgment of different characteristics such as the screening of material sizes and the screening of material colors. Therefore, it is necessary to provide a visual sorting tray for teaching to demonstrate a clever sorting device for students majoring in automation-related majors through this tray, and inspire the design thinking of students. Summary of the Utility Model

[0003] The utility model aims to provide a visual sorting tray for teaching, so as to realize the teaching demonstration of screening and sorting materials according to different characteristics of materials in the teaching of the field of mechanical automation majors through this visual sorting tray for teaching.

[0004] To achieve the above objectives, the utility model adopts the following technical solutions:

A second gap is provided between the material sorting baffle and the rotating bottom plate for the materials to be sorted to pass through and reach the feeding positioning block, and a feeding detection sensor is provided beside the feeding positioning block; a detection sensor bracket is provided beside the base, and a vision sensor is provided on the detection sensor bracket, and the vision sensor is located above the feeding positioning block.

[0006] Preferably, the mixing plate is arranged in the middle of the mixing bracket, and the first gap includes a left feeding gap and a right feeding gap on both sides of the mixing plate.

[0007] Preferably, a material baffle is further provided in the tray housing, and the material baffle is located inside the feeding positioning block and is used to block the materials entering through the second gap.

[0008] Preferably, the base includes a lower adjustable base and an upper adjustable base, and vertically elongated holes are provided on the lower adjustable base and the upper adjustable base to allow a fastening bolt to pass through and clamp the lower adjustable base and the upper adjustable base.

[0009] Preferably, the drive motor is a DC geared motor.

[0010] Preferably, the tray housing includes a bottom plate and an annular peripheral wall.

[0011] Preferably, this visual sorting tray for teaching is used to sort cylindrical materials, and an arc-shaped groove is correspondingly provided on the side of the incoming material positioning block.

[0012] This anti-blocking and material-distributing tray for teaching is used to prevent material jams when there is a large amount of material. The working principle is as follows:

[0013] The materials sorted by this visual sorting tray for teaching are cylindrical materials of different colors. The materials are placed in the tray housing. The DC geared motor drives the rotating bottom plate to rotate through a flange, driving the materials in the tray housing to move. When the materials reach the material sorting baffle, non-standard materials are blocked outside by the limiting effect of the second gap size at the bottom of the material sorting baffle, and the qualified materials move through the second gap to the incoming material positioning block (aluminum block). The incoming material detection sensor transmits a signal to control the vision sensor to detect whether it is the required material. If it is the required material, the external manipulator grabs the material. If it is not the required material, the DC geared motor reverses, drives the material away from the incoming material positioning block position, returns to the mixing plate to disperse the material, and then returns to the previous step after a delay to start cyclic operation until the incoming material is the required material. The materials in this visual sorting tray for teaching can be sorted through the forward and reverse rotation of the DC geared motor and two baffles. The sorting of material characteristics is achieved by the vision sensor. Since the vision sensor is programmable, more diverse sorting functions can be realized.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The visual sorting tray for teaching places a plurality of cylindrical materials on the rotating bottom plate in the tray housing. The driving motor drives the rotating bottom plate to rotate, causing the materials above to move along. Blocked by the mixing plates on the mixing support, cylindrical materials of different colors are mixed together. As the rotating bottom plate continues to rotate, the materials above will move along and reach beside the incoming material positioning block through the second gap between the material sorting baffle and the rotating bottom plate. The incoming material detection sensor detects the material and sends a signal to the control system of the visual sorting tray. The control system controls the visual sensor on the detection sensor support. The visual sensor compares to determine whether the material beside the incoming material positioning block below is the required material, and cooperates with other devices such as a manipulator to achieve the sorting of materials. The visual sorting tray for teaching can achieve the sorting of materials only through the forward and reverse rotation of the DC reduction motor and two baffles. The sorting of material characteristics is achieved by the visual sensor. Since the visual sensor is editable, more diverse sorting functions can be achieved. By intuitively and meticulously demonstrating the principles of material mixing and visual sorting, it provides a vivid and interesting learning teaching aid for students majoring in mechanical automation, which is beneficial to promoting students' understanding of the device structure and principle in material visual sorting and enhancing students' application ability of visual sorting devices.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] In one embodiment, a visual sorting tray for teaching is provided. As Figures 1-5 shown, the visual sorting tray for teaching includes a base 1. A tray housing 2 is provided on the base 1. The tray housing 2 is used to accommodate the conveyed materials. A drive motor 3 is provided at the bottom of the tray housing 2. A rotating base plate 4 is provided inside the tray housing 2. The rotating base plate 4 is connected to the rotating shaft of the drive motor 3 to drive the rotating base plate 4 to rotate in the tray housing 2 through the drive motor 3. There is a small gap between the edge of the rotating base plate 4 and the inner peripheral wall of the tray housing 2, so that the rotating base plate 4 will not rub against the inner peripheral wall of the tray housing 2 when rotating, and the excessive gap is avoided to cause the materials to fall. A mixing support 5 is provided in the tray housing 2. The mixing support 5 is a profile straddling the tray housing 2. A mixing plate 51 is provided on the mixing support 5. There is a first gap 52 between the mixing support 5 and the rotating base plate 4 for the materials to be sorted to pass through. For example, when cylindrical materials of different colors are placed in the tray housing 2, the drive motor 3 drives the rotating base plate 4 to rotate, and the cylindrical materials above will also move accordingly. When the materials touch the mixing plate 51, the materials of different colors will be mixed.

[0024] A material sorting baffle 6 is also provided in the tray housing 2, and an incoming material positioning block 61 is provided inside the material sorting baffle 6. There is a second gap 62 between the material sorting baffle 6 and the rotating base plate 4 for the materials to be sorted to pass through and reach the incoming material positioning block 61. During the process of driving the rotating base plate 4 to rotate by the drive motor 3, the cylindrical materials above will also move accordingly. When the materials enter beside the incoming material positioning block 61 through the second gap 62, they will be blocked by the incoming material positioning block 61. For cylindrical materials, an arc surface is provided on one side of the incoming material positioning block 61, so that the cylindrical materials can just stick to it.

[0025] There is a feeding detection sensor 63 beside the feeding positioning block 61. There is a detection sensor bracket 7 beside the base 1. A vision sensor 71 is provided on the detection sensor bracket 7. The vision sensor 71 is located above the feeding positioning block 61. When the material is conveyed beside the feeding positioning block 61, the feeding detection sensor 63 will send a signal to the control system of this vision sorting tray. The vision sensor 71 on the detection sensor bracket 7 is controlled by the control system. The vision sensor 71 takes pictures and compares to determine whether the material beside the feeding positioning block 61 below is the required material. For example, it determines whether the color of the material is the color of the required material, and cooperates with other devices such as a manipulator to achieve the sorting of materials.

[0026] The teaching demonstration method of this teaching vision sorting tray is as follows: Put multiple cylindrical materials on the rotating bottom plate 4 in the tray housing 2. The driving motor 3 drives the rotating bottom plate 4 to rotate, so that the materials above move along. Blocked by the mixing plate 51 on the mixing bracket 5, cylindrical materials of different colors are mixed together. As the rotating bottom plate 4 continues to rotate, the materials above will move along and reach beside the feeding positioning block 61 through the second gap 62 between the material sorting baffle 6 and the rotating bottom plate 4. The side of the cylindrical material is attached to the arc surface on the side of the feeding positioning block 61. The feeding detection sensor 63 detects the material and sends a signal to the control system of this vision sorting tray. The vision sensor 71 on the detection sensor bracket 7 is controlled by the control system. The vision sensor 71 takes pictures and compares to determine whether the material beside the feeding positioning block 61 below is the required material. For example, it determines whether the color of the material is the color of the required material, and cooperates with other devices such as a manipulator to achieve the sorting of materials. If it is determined that the material is not the required material, the driving motor 3 drives the rotating bottom plate 4 to reverse, so that the material leaves the feeding positioning block 61. Then the driving motor 3 drives the rotating bottom plate 4 to rotate forward again, so that the next material reaches beside the feeding positioning block 61 and is judged again until the material moved over is the required material. This teaching vision sorting tray intuitively and meticulously demonstrates the principles of material mixing and vision sorting, provides a vivid and interesting learning teaching aid for students majoring in mechanical automation, is conducive to promoting students' understanding of the device structure and principles in material vision sorting, and enhancing students' application ability of vision sorting devices.

[0027] Further, as shown in Figures 1-5 In another embodiment, the mixing plate 51 of this teaching vision sorting tray is arranged in the middle of the mixing bracket 5. The first gap 52 includes a left passing gap 521 and a right passing gap 522 on both sides of the mixing plate 51. The gap between the lower edge of the mixing plate 51 and the rotating bottom plate 4 is small and no material can pass through. By setting the left passing gap 521 and the right passing gap 522, it is conducive to the smooth passing of materials on both sides.

[0028] Further, in combination with Figures 1-5 As shown, in another embodiment, the teaching visual sorting tray further includes a material baffle 64 in the tray housing 2. The material baffle 64 is located inside the incoming material positioning block 61 and is used to block the materials entering through the second gap 62. A material trough is formed between the material baffle 64 and the material sorting baffle 6, which can guide the materials to reach beside the incoming material positioning block 61.

[0029] Further, in combination with Figures 1-5 As shown, in another embodiment, the base 1 of the teaching visual sorting tray includes a lower adjustable base 11 and an upper adjustable base 12. The base 1 includes left and right parts, and each part includes a lower adjustable base 11 and an upper adjustable base 12. Among them, the lower adjustable base 11 is an L-shaped plate, and the upper adjustable base 12 is an inverted L-shaped plate. Matching vertical long holes are provided on the lower adjustable base 11 and the upper adjustable base 12 so that fastening bolts can pass through and clamp the lower adjustable base and the upper adjustable base. When the height needs to be adjusted, the bolts can be loosened.

[0030] Further, in combination with Figures 1-5 As shown, in another embodiment, the drive motor 3 of the teaching visual sorting tray is a DC reduction motor, which is convenient for controlling the rotation speed and has a large initial torque, and can meet the usage requirements.

[0031] Further, in combination with Figures 1-5 As shown, in another embodiment, the tray housing 2 of the teaching visual sorting tray includes a bottom plate and an annular peripheral wall. The bottom plate is used to support on the base 1, and the annular peripheral wall enables the materials to move smoothly.
