Description

Technical Field

[0001] The invention relates to the technical field of visual inspection devices, and in particular to a visual inspection device for automobile parts. Background Art

[0002] In the automobile production process, the quality of parts is of vital importance and requires standardized and strict inspection. With the advancement of automobile production technology, the inspection of automobile parts has changed from traditional manual inspection to automated inspection, such as an automobile parts visual inspection device with publication number CN117451726B in the prior art.

[0003] The detection device in the prior art is generally controlled by a computer program, and the detection work is performed automatically. The image of the component is captured by a camera, and then the image is analyzed and processed by computer software. The visual qualification of the component is determined based on the analysis result.

[0004] In addition to testing, it is also necessary to eliminate defective products that fail the test. The so-called elimination is to separate the defective products from other products and collect them for unified subsequent processing, such as a visual inspection device for automotive parts with publication number CN218925351U.

[0005] Although the rejected parts are defective, they cannot be discarded directly. After being rejected and recycled, they can often be reprocessed for repair. The recycled parts are generally stored in the same container. The parts that fall into the container later are very likely to collide with the previously recycled parts. The collision will not only produce noise, but also cause damage to the parts that collide with each other.

[0006] In the prior art, falling parts are often cushioned when they fall into a container to reduce the impact force when they fall, thereby reducing the harm of the collision. However, this method only reduces the force when the parts contact each other, and cannot completely avoid the contact between the parts. Even if the contact force is small, wear will still occur between the contacting parts, making it difficult to fully avoid secondary damage during the removal of parts. Summary of the invention

[0048] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] The present invention provides Figure 1-12 The visual inspection device for automobile parts shown in the figure comprises a hood 13 for protection, a camera 1 6, a camera 2 7, a camera 3 8 and a camera 4 9 are arranged inside the hood 13, a conveyor belt 2 10 is arranged inside the hood 13, the camera 4 9 is arranged on the top of the conveyor belt 2 10, and two rejection mechanisms are arranged on the conveyor belt 2 10;

[0050] A mounting seat 4 is provided inside the hood 13, a separator wheel 5 is provided at the top of the mounting seat 4, the camera 1 6, the camera 2 7 and the camera 3 8 are all provided at the top of the mounting seat 4, the camera 1 6, the camera 2 7 and the camera 3 8 are a group, and the first inspection of the parts is performed, and a conveyor belt 3 14 is provided under the camera 3 8, and the conveyor belt 3 14 is fixed at the top of the mounting seat 4;

[0051] The mounting seat 4 is located on one side of the conveyor belt 2 10, and a conveyor belt 1 3 is provided inside the hood 13. The mounting seat 4 is provided between the conveyor belt 2 10 and the conveyor belt 1 3, and a blanking plate 2 is provided on the rear side of the conveyor belt 1 3. A product placement area 1 is provided on the top of the blanking plate 2, and the product placement area 1 extends to the upper plane of the hood 13.

[0052] The parts to be inspected are placed on the product placement 1, and the blanking plate 2 transports the parts downward to the conveyor belt 1 3, and the conveyor belt 1 3 transports them to the separation wheel 5. The parts can be placed in the notch on the separation wheel 5 and rotate with the separation wheel 5. During the rotation process, the top, bottom and end face of the parts are photographed by the camera 1 6, the camera 2 7, and the camera 3 8 respectively, and then the photographed images are inspected and analyzed using a computer program. Then, the separation wheel 5 rotates to place the parts on the conveyor belt 3 14, and the conveyor belt 3 14 transports the parts to the conveyor belt 2 10. The conveyor belt 2 10 transports the parts and continues to move. When it moves to the first rejection mechanism, the defective products are rejected according to the results of the first detection;

[0053] The qualified products that remain continue to move, and when they move to camera four 9, camera four 9 performs a second inspection on them, and performs a second inspection on various parts of the surface of the parts. The standards of the first inspection and the second inspection are the same. The captured images are used to detect whether there are defects, cracks, deformations and other abnormal conditions on the surface of the parts. The difference is that the two inspections are carried out at different locations. After the inspection, the parts move to the second rejection mechanism, and the parts are rejected for a second time according to the results of the second inspection. Finally, the qualified products that remain are transported through conveyor belt two 10. The output end of conveyor belt two 10 extends to the outside of the hood 13, and the qualified parts are output, thereby completing the entire inspection process. Visual inspection belongs to the existing technology and will not be elaborated here.

[0054] The defective products separated by the rejection mechanism are collected together, such as Figure 5 ,9 As shown in FIG. 11 , the rejection mechanism includes a recycling box 11 , a recycling channel 16 is fixedly provided at the top of the recycling box 11 , rubber particles 26 are contained inside the recycling box 11 , a filter screen 25 is provided on the inner wall of the recycling box 11 , the filter screen 25 is buried inside the rubber particles 26 , a circulation component 20 is provided on the front wall of the recycling box 11 , the rubber particles 26 can pass through the filter screen 25 , but the parts cannot pass through the filter screen 25 ;

[0055] The circulation assembly 20 includes a plurality of circulation channels 2002 fixedly arranged on the front side of the recycling box 11, and a plurality of circulation ports 28 are opened on the front side of the recycling box 11, and the circulation ports 28 correspond to the circulation channels 2002 one by one and communicate with the corresponding circulation channels 2002. A conveying shaft 2004 capable of rotating and transporting rubber particles 26 is arranged inside the circulation channel 2002, and the conveying shaft 2004 is rotatably connected to the inner wall of the circulation channel 2002;

[0056] A plurality of discharge pipes 2008 are fixedly provided on the inner wall of the recovery box 11, and a discharge groove 2009 is opened at the bottom end of the discharge pipe 2008. The discharge pipe 2008 corresponds to the circulation channel 2002 one by one and the rear end of the discharge pipe 2008 is connected to the corresponding circulation channel 2002. The discharge pipe 2008 and the circulation port 28 are respectively located at the top and bottom of the filter 25.

[0057] The rejected defective products first fall into the recycling channel 16 and fall along the recycling channel 16 to the inside of the recycling box 11. The recycling box 11 is filled with rubber particles 26, which play a buffering role in the process of defective products falling. When the defective products reach the surface of the rubber particles 26, the rubber particles 26 at the bottom layer enter the circulation channel 2002 through the circulation port 28. As the conveying shaft 2004 rotates, the rubber particles 26 are transported upward. Finally, the rubber particles 26 enter the discharge pipe 2008 and are re-sprinkled on the surface of the rubber particles 26 through the discharge trough 2009, so that the rubber particles 26 are continuously circulated and the rubber particles 26 at the bottom layer are transported to the surface. In this way, the defective products originally falling on the surface of the rubber particles 26 will be re-covered by the spilled rubber particles 26 and then buried in the rubber particles 26.

[0058] When new defective products fall into the recycling box 11, the original defective products are no longer on the surface of the rubber particles 26, so there will be no contact or collision between the two, and the damage caused by this will be completely avoided. As the rubber particles 26 at the bottom layer continue to flow to the surface, the defective products buried in the rubber particles 26 will gradually move downward, and finally stay on the top of the filter screen 25 under the action of the filter screen 25.

[0059] All conveying shafts 2004 rotate synchronously, such as Fig.10As shown, both sides of the recycling box 11 are provided with sealed doors through hinges, and the sealed doors can be opened to add rubber particles 26, or to take out defective products remaining in the recycling box 11. An elastic lower inclined plate 24 is fixedly provided on the inner wall of the recycling box 11, and the lower inclined plate 24 is made of rubber material. The defective products falling into the recycling box 11 are guided to the bottom of the discharge pipe 2008 along the lower inclined plate 24 so as to be buried. An inclined block 27 with a guiding function is fixedly provided at the bottom end of the recycling box 11, and the inclined block 27 is inclined toward the circulation port 28, so that the rubber particles 26 move toward the circulation port 28.

[0060] A transmission box 2001 is fixedly provided on the front side of the recycling box 11, and a detachable inspection panel is provided on the front side of the transmission box 2001 to facilitate the inspection of the internal components of the transmission box 2001. The top of the circulation channel 2002 extends to the interior of the circulation channel 2002 and is fixedly provided with a lower bevel gear 2006. A transmission shaft 2005 is rotatably connected to the inner wall of the transmission box 2001, and a plurality of upper bevel gears 2007 are fixedly provided on the outer end of the transmission shaft 2005. The upper bevel gears 2007 correspond to the lower bevel gears 2006 one by one and mesh with the corresponding lower bevel gears 2006. A driving motor 2003 for driving the transmission shaft 2005 is fixedly provided on one side of the transmission box 2001.

[0061] During the circulation of the rubber particles 26, the drive motor 2003 drives the transmission shaft 2005 to rotate, and the upper bevel gear 2007 at the outer end of the transmission shaft 2005 rotates synchronously. The upper bevel gear 2007 drives the lower bevel gear 2006 meshing with it to rotate, thereby driving all the conveying shafts 2004 to rotate synchronously to transport the rubber particles 26.

[0062] In order to further improve the protection effect of defective products, such as Fig. 9 , 11 As shown in 12, an elastic upper inclined plate 30 is hinged on the inner wall of the recovery channel 16, and the surface of the upper inclined plate 30 can be covered with a layer of rubber to play an elastic buffering role. A spring 31 is fixed at the bottom end of the upper inclined plate 30, and the bottom end of the spring 31 is connected to the inner wall of the recovery channel 16;

[0063] An external cover 18 communicating with the interior of the recovery channel 16 is disposed at the front side of the recovery channel 16 , and two atomizing nozzles 15 are disposed inside the external cover 18 .

[0064] The top of the recovery box 11 is provided with a detachable anti-rust oil tank 19, and the anti-rust oil tank 19 stores viscous anti-rust oil. The anti-rust oil tank 19 is provided with two oil delivery pipes 29 for delivering the anti-rust oil. The bottom of the oil delivery pipes 29 is immersed in the anti-rust oil, and the top of the oil delivery pipes 29 passes through the top cover of the anti-rust oil tank 19 and extends to the inside of the external cover 18.

[0065] Two atomizing nozzles 15 are fixedly mounted at one end of two oil pipes 29, on which a liquid pump 17 is fixedly mounted. The atomizing nozzles 15 atomize the anti-rust oil and then spray it out. The process of spraying the anti-rust oil is the same as the process of rejecting, which is controlled by a program and will only work when defective products appear, and will not spray the anti-rust oil continuously.

[0066] The defective products falling into the recovery channel 16 first fall on the surface of the upper inclined plate 30, which rotates downward under the impact of the defective products, and the spring 31 is compressed. Then the defective products continue to fall along the inclined upper inclined plate 30, so that the movement of the defective products can be buffered during the falling process, and the defective products can also be slightly paused at the upper inclined plate 30;

[0067] While the defective products are at a standstill, driven by the liquid pump 17, the lubricating oil stored in the anti-rust oil tank 19 flows out along the oil pipe 29 and is sprayed out through the atomizing nozzle 15, so that the anti-rust oil is sprayed on the surface of the defective products. Firstly, it can play an anti-rust role. Secondly, the anti-rust oil has a certain viscosity. When the defective products coated with the anti-rust oil fall into the recycling box 11, a layer of rubber particles 26 can be adhered to the surface thereof by virtue of the viscosity of the anti-rust oil. The outer diameter of the rubber particles 26 is about 2 mm. The rubber particles 26 adhered to the surface thereof have a blocking effect, which can further prevent the defective products inside the recycling box 11 from contacting each other. The defective products cannot contact each other, thereby further avoiding the wear caused thereby.

[0068] If the parts transported on the conveyor belt 10 are defective, they need to be moved to the recycling channel 16. Figure 6 As shown, the rejection mechanism further includes a rejection channel 12, the rejection channel 12 is located at the top of the conveyor belt 10, the front end of the rejection channel 12 is connected to the entrance of the recovery channel 16 by bolts, and the rear end of the rejection channel 12 is connected to the conveyor belt 10 by bolts;

[0069] Two cylinders 21 are provided on the rear wall of the rejection channel 12, and a push plate 22 is provided inside the rejection channel 12. One end of the piston rod of the cylinder 21 extends into the rejection channel 12 and is fixedly connected to the push plate 22. The push plate 22 moves by the extension and retraction of the piston rod of the cylinder 21.

[0070] The parts are at the top of the conveyor belt 10 and are transported as the conveyor belt 10 moves. When defective parts are found after visual inspection, the defective parts move to the front side of the push plate 22, and the piston rod of the cylinder 21 extends to push the push plate 22. The push plate 22 pushes the defective parts forward to the entrance of the recovery channel 16, causing them to fall into the recovery channel 16 for removal.

[0071] Before moving, lubrication oil needs to be applied to the surface of the defective product, such as Figure 6 , 7 As shown, a pressing assembly 23 is provided on the rejection channel 12, and the pressing assembly 23 includes an oil cylinder 2301 fixedly provided at the top of the rejection channel 12, and a piston rod of the oil cylinder 2301 extends downward to the inside of the rejection channel 12 and is fixedly provided with a fixing plate 2302;

[0072] Two pressing rollers 2304 are provided at the bottom of the fixed plate 2302 . The surface of the pressing rollers 2304 is covered with a layer of cotton cloth. Both ends of the pressing rollers 2304 are rotatably connected with end pieces 2303 . The end pieces 2303 are fixed at the bottom of the fixed plate 2302 .

[0073] For common cylindrical automotive parts, when a defective product moves to the front side of the push plate 22, before being pushed forward by the push plate 22, the cylinder 2301 first pushes the fixed plate 2302 to move, so that the fixed plate 2302 moves down, and the two pressure rollers 2304 at the bottom of the fixed plate 2302 contact the defective cylindrical automotive parts. The top end of the defective product is stuck between the two pressure rollers 2304, and the bottom end contacts the conveyor belt 2 10. Under the action of friction, the conveyor belt 2 10 runs and causes the defective product to roll, and the two pressure rollers 2304 also roll therewith, but the position of the defective product relative to the pressing assembly 23 remains unchanged, thereby temporarily fixing the defective product.

[0074] The lubricant needs to be guided and applied, such as Figure 6-8 As shown, the pressing assembly 23 further includes two lubricating oil tanks 2307 located at the top of the rejecting channel 12. Lubricating oil is stored in the lubricating oil tanks 2307. A detachable top cover 2308 is provided at the top of the lubricating oil tanks 2307.

[0075] The lubricating oil tank 2307 is provided with a plurality of hooks fixed to the bottom end of the top cover 2308, and a plurality of cotton drainage ropes 2306 are hung on the hooks. A rubber hose 2305 is fixed to the outer end of the cotton drainage rope 2306. The upper end of the cotton drainage rope 2306 is exposed outside the rubber hose 2305 and immersed in the lubricating oil in the lubricating oil tank 2307, and the hooks are located above the liquid level of the lubricating oil.

[0076] The lower ends of the rubber hose 2305 and the cotton drainage rope 2306 pass through the fixed plate 2302, and the lower end of the cotton drainage rope 2306 is also exposed outside the rubber hose 2305. The cotton drainage ropes 2306 corresponding to the two lubricating oil tanks 2307 are respectively located on the top of the two pressure rollers 2304. The cotton drainage rope 2306 can absorb the lubricating oil and drip the lubricating oil onto the pressure roller 2304. The dripping lubricating oil is absorbed by the cotton cloth on the surface of the pressure roller 2304.

[0077] During the short process of fixing the defective products, the cotton drainage rope 2306 soaked in lubricating oil absorbs the lubricating oil and drains the lubricating oil in the lubricating oil tank 2307 to the top of the pressure roller 2304. Under the action of gravity, the lubricating oil on the cotton drainage rope 2306 that has absorbed the lubricating oil drips and is absorbed on the cotton cloth on the surface of the pressure roller 2304. Then, during the rolling process of the defective products, the lubricating oil is smeared on the surface of the defective products through the pressure roller 2304. Then, the pressure roller 2304 moves upward, and the push plate 22 pushes the defective products forward. At this time, the conveyor belt 210 moves horizontally left and right, and the pushed defective products move forward longitudinally. During the forward movement, friction is inevitable between the defective products and the conveyor belt 210. However, due to the lubricating oil on the surface, the friction between the defective products and the conveyor belt 210 is greatly reduced, which not only reduces the wear caused by this, but also makes the removal process smoother. The process of applying lubricating oil and pushing the defective products forward for removal needs to be carried out in a short time to avoid interference with the subsequent moving parts.

[0078] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
