Description

Technical Field

[0001] This utility model relates to the field of sorting technology, and in particular to an automatic sorting conveyor belt with visual recognition. Background Technology

[0002] Automated sorting conveyor belts are an important component of logistics automation technology. They combine mechanical, electronic, computer, and control technologies to automate tasks such as sorting, classifying, packaging, and transporting goods. In automated sorting conveyor belts with vision recognition, vision recognition is the core element. It utilizes advanced image recognition and processing technologies, combined with technologies such as the Internet of Things and artificial intelligence, to quickly and accurately identify and classify goods on the conveyor belt.

[0003] A search revealed Chinese patent CN217017485U, which discloses an automatic sorting device based on visual recognition. This device addresses the issue that, while maintaining sorting efficiency, the spacing between parts and the conveyor speed are fixed. Due to the single conveyor line and high speed, when defective products are detected consecutively on a single conveyor line within a short period, the air nozzles cannot react in time, leading to missed defective products. Since the number of consecutive defective product detections is not high, changing the conveyor speed or part spacing would significantly reduce overall production efficiency and hinder the timely output of superior products. Therefore, by setting up a feeding unit and a visual sorting unit, a second conveyor belt is connected to one end of the second conveyor belt to form a dual conveyor route for parts diversion and simultaneous detection. Two sets of air nozzles are used to sort the parts on the second conveyor belt, expanding the detection spacing for consecutive defective products and improving the air nozzle response.

[0004] The aforementioned automated sorting conveyor belt improves sorting quality. However, in existing technologies, after material identification and detection, when using cylinders to push defective products for sorting, the cylinder's thrust needs to be rapid and accurate, resulting in a relatively large pushing force on the defective products. When the defective products are directly pushed into the receiving frame, the receiving frame is relatively deep, and under the action of the cylinder's pushing force, the defective products collide with the inside of the receiving frame, easily generating bidirectional forces between the receiving frame and the defective products. Without protection, this collision can cause damage, increasing the maintenance cost of automated sorting. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic sorting conveyor belt with visual recognition, comprising a housing, a conveyor belt body disposed inside the housing, a fixed frame fixedly connected to the upper surface of the housing, a scanning camera, an infrared sensor, and two lighting lamps fixedly installed on the inner wall of the fixed frame, the scanning camera being disposed on one side of the infrared sensor, and the two lighting lamps being disposed on both sides of the scanning camera and the infrared sensor, a fixed plate fixedly connected to one side of the housing, a cylinder fixedly installed on the upper surface of the fixed plate, a push plate fixedly connected to the output end of the cylinder, two connecting rods fixedly connected to one side of the push plate, two fixed brackets fixedly connected to the upper surface of the fixed plate, one end of the connecting rods being slidably connected to the outside of the fixed brackets, and a protective component disposed on the other side of the housing.

[0007] As a further description of the above technical solution:

[0008] The protective component includes a feeding frame, which is fixedly connected to the other side of the housing. An inclined plate is fixedly connected inside the feeding frame, and two connecting grooves are formed on the upper surface of the inner wall of the feeding frame.

[0009] As a further description of the above technical solution:

[0010] The upper surface of the inner wall of the feeding frame is provided with multiple grooves, and two connecting grooves are arranged on both sides of the multiple grooves. A fixing ring is fixedly connected to the inner wall of the groove, and a buffer spring is fixedly connected inside the groove. One end of the buffer spring is fixedly connected to a T-shaped post, and one end of the multiple T-shaped posts is fixedly connected to multiple buffer plates. The buffer plates are slidably connected inside the two connecting grooves, and a buffer block is fixedly connected to one side of the feeding frame.

[0011] As a further description of the above technical solution:

[0012] Two limiting grooves are provided on one side of the feeding frame. A hydraulic cylinder is fixedly installed on one side of the feeding frame. An opening and closing plate is fixedly connected to the output end of the hydraulic cylinder. Two limiting blocks are fixedly connected to one side of the opening and closing plate. The limiting blocks are slidably connected inside the limiting grooves.

[0013] As a further description of the above technical solution:

[0014] The upper surface of the feeding frame is provided with a pushing mechanism, which includes a limiting frame and a first stepper motor. The limiting frame and the first stepper motor are fixedly connected to the upper surface of the feeding frame.

[0015] As a further description of the above technical solution:

A support rod is hinged to one side of each connecting block, and a pusher plate is hinged to one end of each support rod. A sliding groove is provided on the lower surface of the mounting frame, and the two connecting blocks are slidably connected inside the sliding groove.

[0019] This utility model has the following beneficial effects:

[0020] 1. By setting up protective components, this utility model increases the buffering force of the buffer spring when the automatic sorting conveyor belt pushes and discharges defective products after visual recognition. The use of the ramp plate and buffer block helps to reduce the large impact force generated by the vertical discharge of defective products. This reduces the phenomenon that defective products will directly contact the receiving box and generate bidirectional collision force due to the large pushing force, thus preventing damage to the receiving box and defective products.

[0021] 2. This utility model, through the setting of the pushing mechanism, automatically discharges the defective materials accumulated inside the feeding box after the automatic sorting conveyor belt performs visual recognition sorting. It eliminates the need for manual pushing of the large amount of defective materials accumulated after sorting into the receiving box. This reduces the phenomenon that when defective materials are discharged, the pusher plate cannot push the defective materials because they are accumulated inside the feeding box and are not processed in time, causing defective materials to be discharged along with qualified products, resulting in sorting errors. This helps to reduce the workload of operators. Attached Figure Description

The buffer plates 19 are slidably connected inside the two connecting grooves 14. The ramp plate 13 helps to prevent the large impact force generated by the vertical fall of defective products. The grooves 15 facilitate the installation of the buffer spring 17 and the retractable T-shaped post 18. The buffer plates 19 play a buffering role for defective products.

[0034] As attached Figure 3 As shown, a buffer block 20 is fixedly connected to one side of the feeding frame 12, two limit grooves 21 are opened on one side of the feeding frame 12, a hydraulic cylinder 22 is fixedly installed on one side of the feeding frame 12, and an opening and closing plate 23 is fixedly connected to the output end of the hydraulic cylinder 22. The buffer block 20 facilitates the buffering and guiding of defective products when they are fed out.

[0035] As attached Figure 5 As shown, two limiting blocks 24 are fixedly connected to one side of the opening and closing plate 23. The limiting blocks 24 are slidably connected inside the limiting groove 21 and play a limiting role for the opening and closing plate 23.

[0036] As attached Figure 4As shown, a pushing mechanism is provided on the upper surface of the feeding frame 12. The pushing mechanism includes a limiting frame 25 and a first stepper motor 26. The limiting frame 25 and the first stepper motor 26 are fixedly connected to the upper surface of the feeding frame 12. The first stepper motor 26 is fixedly installed on one side of the limiting frame 25. A screw 27 is fixedly connected to the output end of the first stepper motor 26. A moving block 28 is threadedly connected to the external side of the screw 27. A mounting rod 29 is fixedly connected to one side of the moving block 28. A mounting frame 30 is fixedly connected to one end of the mounting rod 29. A second stepper motor 26 is fixedly installed inside the mounting frame 30. The output end of the first stepper motor 31 is fixedly connected to a bidirectional lead screw 32. The bidirectional lead screw 32 is rotatably connected inside the mounting frame 30. The external thread of the bidirectional lead screw 32 is connected to two connecting blocks 33. A support rod 34 is hinged to one side of the connecting block 33. A pusher plate 35 is hinged to one end of the two support rods 34. The screw 27 facilitates the movement of the moving block 28 under the limiting action of the limiting frame 25. The external thread of the bidirectional lead screw 32 is set to opposite directions. The support rod 34 facilitates the movement of the pusher plate 35.

[0037] As attached Figure 6 As shown, a groove 36 is provided on the lower surface of the mounting frame 30, and two connecting blocks 33 are slidably connected inside the groove 36, which limits the movement of the connecting blocks 33.

[0038] Working principle: When in use, first turn on the conveyor belt body 2, place the material on the top of the conveyor belt body 2 and when it is conveyed, the material will pass under the fixed frame 3. With the assistance of the lighting lamp 6, it will be scanned and identified by the scanning camera 4 and infrared sensor 5. Based on the captured features such as the shape, color, size and movement status of the item, the information is transmitted to the external control system. The external control system processes the captured information according to the preset rule algorithm and sends the command to the cylinder 8. After receiving the command, the output end of the cylinder 8 drives the push plate 9 to quickly push the defective product into the inside of the unloading frame 12.

[0039] When defective products enter the feeding frame 12, a receiving frame is placed on one side of the feeding frame 12 to catch the material. First, the material is buffered by the slope of the ramp plate 13. Then, when the product falls onto the buffer plate 19, it is pressed down by the impact force. The buffer plate 19 is pressed against multiple T-shaped posts 18, which in turn press against the buffer spring 17. After the buffer spring 17 rebounds under pressure, it drives the buffer plate 19 to slide inside the connecting groove 14 under the connection of the T-shaped posts 18, thereby playing a protective buffering role for defective products.

[0040] Then, the hydraulic cylinder 22 is activated, and its output end drives the opening and closing plate 23 to rise, causing the opening and closing plate 23 to drive the limiting block 24 to slide inside the limiting groove 21, opening the outlet of the feeding frame 12. Then, the second stepper motor 31 is started, and its output end, under the influence of the internal gearbox, drives the bidirectional lead screw 32 to rotate inside the mounting frame 30. The bidirectional lead screw 32 drives the external connecting block 33 to move. Under the action of the opposite direction threads on the outside of the bidirectional lead screw 32, the two connecting blocks 33 on both sides move closer to each other, causing the support rod 34 to be lifted, thereby driving the pusher plate 35 to move above the buffer plate 19. Then, the first stepper motor 26 is activated, and its output end, under the influence of its own gearbox, drives the screw 27 to rotate. The screw 27 drives the moving block 28 and the mounting rod 29 to move, thereby indirectly driving the pusher plate 35 to move inside the feeding frame 12, pushing the defective products out of the frame.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
