Abstract
Description
Technical Field
[0001] This utility model relates to the field of appearance inspection technology, and in particular to a metal product appearance inspection and sorting device. Background Technology
[0002] Metal appearance inspection is the process of examining and evaluating the surface condition of metal products. Its purpose is to detect whether there are defects, damage, or non-compliance with quality standards on the surface of metal products, so as to ensure that the product quality and performance meet the requirements. Currently, the metal appearance inspection process mainly relies on manual inspection. Manual inspection mainly relies on visual observation, supplemented by simple measuring tools. Since both sides of the metal products need to be observed, measured, and judged, and damaged metal products need to be sorted, the whole process is time-consuming and seriously reduces the inspection efficiency. Especially for some metal items that require precise data for classification, manual sorting is difficult to classify accurately and is prone to misjudgment. Utility Model Content

Detailed Implementation
[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0019] Example: A metal product appearance inspection and sorting device, such as Figure 1-3As shown, the device includes a support base 2, a first conveyor belt 3, a second conveyor belt 301, a third conveyor belt 302, an inspection machine 4, an electric push rod 5, a push plate 6, a roller 7, a motor 8, a drive wheel 9, a synchronous pulley 10, a fixing block 11, a rotating shaft 12, a limit block 13, a synchronous belt 14, and a pneumatic gripper 15. A groove 201 is provided on the left front of the support base 2. The first conveyor belt 3 and the second conveyor belt 301 are mounted on the support base 2, with the first conveyor belt 3 located behind the second conveyor belt 301. The third conveyor belt 302 is mounted on the right side of the support base 2, located in the middle right side of the second conveyor belt 301. The second conveyor belt 301 and the third conveyor belt 302 are perpendicular to each other in a T-shaped arrangement. Two inspection machines 4 are mounted on the support base 2, located above the first conveyor belt 3 and the second conveyor belt 301, respectively. The inspection machines 4 can inspect the appearance of metal products. A fixed connection is provided on the left front of the support base 2. An electric push rod 5 is rotatably connected to a push plate 6. The bottom rear side of the push plate 6 slides with a sliding groove 201 via a sliding shaft. Multiple rollers 7 are connected to the right side of the push plate 6. A controller is installed on the support base 2. The detection machine 4 and the electric push rod 5 are both electrically connected to the controller. A motor 8 is fixedly connected to the support base 2. A drive wheel 9 is fixedly connected to the output shaft of the motor 8. A synchronous wheel 10 is fixedly connected to the drive wheel 9. A fixing block 11 is symmetrically fixedly connected to the middle of the support base 2. A rotating shaft 12 is rotatably connected to the fixing block 11. A limit block 13 is fixedly connected to the rotating shaft 12. The limit block 13 is U-shaped. Another synchronous wheel 10 is fixedly connected to the rotating shaft 12. This synchronous wheel 10 and the synchronous wheel 10 on the drive wheel 9 are distributed vertically. The synchronous wheels 10 are located between the first conveyor belt 3 and the second conveyor belt 301. A synchronous belt 14 is wound around the two synchronous wheels 10. A pneumatic gripper 15 is fixedly connected to the end of the limit block 13.
[0020] like Figure 1 and Figure 4 As shown, it also includes a guide plate 16 and a torsion spring 17. The front and right sides of the support base 2 are rotatably connected to the guide plate 16. The two guide plates 16 are located at the tail of the second conveyor belt 301 and the third conveyor belt 302, respectively. The torsion spring 17 is sleeved between the guide plate 16 and the support base 2.
[0021] like Figure 2-4 As shown, it also includes baffles 18. Baffles 18 are fixedly connected to the support seats 2 on both sides of the first conveyor belt 3, the second conveyor belt 301 and the third conveyor belt 302. The inner side of the baffles 18 is a felt structure. The baffles 18 can prevent metal products from falling from both sides of the conveyor belt during the conveying process, and ensure the smooth progress of the entire inspection and sorting process.
[0022] like Figure 1 and Figure 4As shown, it also includes a collection frame 19. The collection frame 19 is placed at the tail of both the second conveyor belt 301 and the third conveyor belt 302. The collection frame 19 is located below the guide plate 16.
[0023] like Figure 3 As shown, it also includes an anti-slip pad 20. The pneumatic gripper 15 is fixedly connected to the anti-slip pad 20, which is made of rubber.
[0024] like Figure 1 As shown, it also includes a light-blocking curtain 21, and the front and rear sides of the testing machine 4 are fixedly connected with the light-blocking curtain 21.
[0025] First, the feeder 1 is placed behind the support frame, aligning its outlet with the rear end of the first conveyor belt 3. Then, the metal products to be inspected are placed on the feeder 1, and the feeder 1 is started. The internal conveying mechanism of the feeder 1 sorts the metal products, which are then intermittently and orderly fed out of the outlet and transported to the first conveyor belt 3. The inspection machine 4, located above the first conveyor belt 3, performs visual inspection on the passing metal products. The light-shielding curtain 21 connected to the inspection machine 4 reduces interference from external light during the inspection process. To improve the accuracy of the inspection, the first conveyor belt 3 carries the inspected metal products out of the inspection machine 4. When the metal products move into the working range of the pneumatic gripper 15, the pneumatic gripper 15 starts to grip the metal products. The rubber anti-slip pad 20 fixedly connected to the pneumatic gripper 15 can increase the friction and ensure that the metal products will not slip during the gripping process. After the metal products are gripped, the motor 8 starts. Driven by the motor 8, the motor 8 drives the drive wheel 9 to rotate 180° clockwise, which in turn drives the rotating shaft 12 to rotate through the synchronous pulley 10 and the synchronous belt 14. The motor rotates 180°, causing the limiting block 13 and pneumatic gripper 15, which are fixedly connected to the rotating shaft 12, to rotate 180°. After the pneumatic gripper 15 rotates, it releases the metal product it has gripped. At this time, the metal product is flipped 180° and placed on the second conveyor belt 301. Then, the motor 8 rotates counterclockwise, driving the pneumatic gripper 15 to rotate 180° to reset and grip the next metal product. The flipped metal product is transported to the next inspection machine 4 via the second conveyor belt 301 for further inspection. For metal products that pass the inspection, they will continue to be transported by the second conveyor belt. As the conveyor belt 301 moves, when a qualified product reaches the tail of the second conveyor belt 301, it will come into contact with the guide plate 16 at the tail of the second conveyor belt 301. After the guide plate 16 is subjected to the weight of the qualified product, the tail of the guide plate 16 is pressed down. The torsion spring 17 inside the guide plate 16 can rotate at a certain angle according to the weight of the qualified product, which plays a role in guiding the qualified product to fall and provides a certain buffer for the fall of the qualified product. The qualified product slides down along the guide plate 16 into the collection frame 19 placed below the tail of the second conveyor belt 301, completing the collection of the qualified product. The torsion spring 17 drives the guide plate 16 to reset.
[0026] When the inspection machine 4 detects a metal product that does not meet the appearance standards, the inspection machine 4 sends a signal to the controller. The controller controls the electric push rod 5 to start. The telescopic rod of the electric push rod 5 extends towards the second conveyor belt 301. The front end of the push plate 6 moves to the right. Under the cooperation of the sliding shaft and the sliding groove 201, the push plate 6 is tilted and blocks above the second conveyor belt 301. When the second conveyor belt 301 drives the metal product forward and contacts the push plate 6, the push plate 6 can guide the metal product to the third conveyor belt 302. The roller 7 can reduce the friction between the metal product and the push plate 6, prevent the push plate 6 from causing further damage to the metal product, and also ensure that the metal product moves smoothly. When the defective product runs to the end of the third conveyor belt 302, the defective product causes the guide plate 16 to move under its own gravity and then falls into the collection frame 19.
[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
