Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to a visual inspection reversal device. Background Technology

[0002] With the advancement of the industrial age, many factories have implemented automated production lines, leading to higher demands for product quality and production capacity. During the production process, uncontrollable factors in the production and transportation environment often result in products suffering from scratches, dents, and dimensional inconsistencies. Traditional inspection methods typically involve manually processing finished products offline before manual inspection. However, manual inspection is susceptible to subjective factors, leading to issues such as low accuracy, efficiency, and consistency, directly impacting product quality and production capacity. Currently, most vision systems on the market prefer to perform separate secondary inspections after products are offline, which is not only inefficient but also carries a high risk of product damage during the process. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to propose a visual inspection reversal device that can directly connect to the production output equipment, reducing human intervention. After production, the products are directly subjected to visual inspection and sorting, realizing the sorting and conveying of good and defective products. This method is less likely to damage the products, effectively reduces labor costs, and solves the problems of low inspection accuracy, efficiency, and product consistency caused by manual inspection.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0014] The defective product conveying roller assembly includes multiple defective product conveying rollers rotatably mounted on the frame. The multiple defective product conveying rollers are arranged at intervals in a front-to-back direction. The second reversing fixture in the defective product reversing assembly is located above the gap between two defective product conveying rollers.

[0015] The reversing mechanism also includes a plurality of feeding support frames disposed on the frame. The feeding support frames are spaced apart in the front-to-back direction.

[0016] The first reversing fixture has a return hook at the end away from the rotating shaft, and the second reversing fixture has a return hook at the end away from the rotating shaft.

[0017] Specifically, the reversing mechanism further includes a feed baffle and a discharge baffle. The feed baffle is located on the side of the feed station away from the feed conveyor belt. The discharge baffle is located on the side of the good product conveyor roller group away from the good product conveyor belt, and the discharge baffle is located on the side of the defective product conveyor roller group away from the defective product conveyor belt.

[0018] Furthermore, it also includes a through-beam mechanism, which is disposed between the feeding station and the feeding conveyor belt. The through-beam mechanism includes a through-beam sensor and a base disposed opposite to each other. The base is fixedly disposed on the upper surface of the frame, and the through-beam sensor is disposed on the base.

[0019] To further explain, the visual inspection mechanism includes an image acquisition component, a visual multi-axis adjustment component, and a visual gantry. The visual gantry is fixedly mounted on the frame, the visual multi-axis adjustment component is mounted on the frame, the image acquisition component is connected to the movable end of the visual multi-axis adjustment component, and the visual multi-axis adjustment component is used to adjust the position of the image acquisition component.

[0020] To further explain, the vision multi-axis adjustment assembly includes a first slide rail, a first slider, a second slide rail, a second slider, a third slide rail, a third slider, and multiple bolts;

[0021] The first slide rail is disposed on the visual gantry in the front-back direction, and the first slider is slidably disposed on the first slide rail in the front-back direction;

[0022] The second slide rail is fixedly connected to the first slider. The second slide rail is arranged in the left-right direction, and the second slider is slidably arranged on the second slide rail in the left-right direction.

[0023] The third slide rail is fixedly connected to the second slider, the third slide rail is arranged in the vertical direction, and the third slider is slidably arranged on the third slide rail in the vertical direction;

[0024] The sidewalls of the first slider, the second slider, and the third slider are respectively provided with mounting holes, and the bolts are respectively tightened into the corresponding mounting holes.

Detailed Implementation

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0039] like Figures 1 to 5 As shown, a visual inspection reversing device includes a frame 1, a reversing mechanism 2, a visual inspection mechanism 3, a feeding conveyor belt 4, a good product conveyor belt 5, and a defective product conveyor belt 6.

[0040] The reversing mechanism 2 is disposed on the frame 1, and the reversing mechanism 2 includes a good product conveying roller group 21, a good product reversing component 23, a defective product conveying roller group 22, and a defective product reversing component 24;

[0041] The good product conveying roller group 21 and the defective product conveying roller group 22 are respectively arranged on the left and right sides of the frame 1. A feeding station 41 is provided between the good product conveying roller group 21 and the defective product conveying roller group 22. The feeding station 41 is located at the discharge end of the feeding conveyor belt 4. The discharge end of the good product conveying roller group 21 is connected to the feeding end of the good product conveyor belt 5, and the discharge end of the defective product conveying roller group 22 is connected to the feeding end of the defective product conveyor belt 6.

[0042] The visual inspection mechanism 3 is located above the feeding station 41. The good product reversal component 23 and the defective product reversal component 24 are respectively located on the left and right sides of the feeding station 41. The good product reversal component 23 is used to reverse the product on the feeding station 41 to the good product conveying roller group 21, and the defective product reversal component 24 is used to reverse the product on the feeding station 41 to the defective product conveying roller group 22.

[0043] The product is fed into the production discharge equipment via the feeding conveyor belt 4, allowing the product to directly enter the feeding station 41 after production. The vision inspection mechanism 3 above the feeding station 41 captures images of the product and performs inspection and judgment. If the product is judged to be good, the good product reversing component 23 reverses the product 180° to the good product conveyor roller group 21. Since the discharge end of the good product conveyor roller group 21 is connected to the feed end of the good product conveyor belt 5, the product judged to be good will be conveyed on the good product conveyor belt. The good product conveyor belt 5 can be connected to the assembly equipment of the next station to directly transport the good product to the next station. If the product is judged to be defective, the defective product reversing component 24 will reverse the product 180° to the defective product conveying roller group 22. The discharge end of the defective product conveying roller group 22 is connected to the feed end of the defective product conveyor belt 6. Therefore, the product judged to be defective will be sent out under the conveying of the defective product conveyor belt 6 (the defective product conveyor belt 6 can be connected to the defective product frame to directly transport the defective product to the defective product frame for collection and processing).

[0044] The aforementioned visual inspection reversal equipment directly connects to the production output equipment, reducing human intervention. Finished products are directly subjected to visual inspection and sorting, enabling the sorting and conveying of good and defective products without easily damaging them. This effectively reduces labor costs and solves the problems of low inspection accuracy, efficiency, and product consistency caused by manual inspection.

[0045] It is worth noting that the good product reversal assembly 23 has the same structure as the defective product reversal assembly 24. The good product reversal assembly 23 includes a first drive device 231, a rotating shaft 232 and a plurality of reversal fixture groups 233. The rotating shaft 232 is arranged along the conveying direction of the good product conveying roller group 21.

[0046] The reversing fixture group 233 is spaced apart from the rotating shaft 232. The reversing fixture group 233 includes a first reversing fixture 2331 and a second reversing fixture 2332 horizontally arranged on the rotating shaft 232. The included angle between the first reversing fixture 2331 and the second reversing fixture 2332 is 180°. The first reversing fixture 2331 is arranged corresponding to the feeding station 41, and the second reversing fixture 2332 is arranged corresponding to the good product conveying roller group 21.

[0047] The output end of the first driving device 231 is connected to the rotating shaft 232. The first driving device 231 drives the rotating shaft 232 to rotate, thereby driving the first reversing fixture 2331 and the second reversing fixture 2332 to perform a 180° reversing motion.

[0048] It should be noted that the first reversing fixture 2331 in the defective product reversing assembly 24 is set corresponding to the feeding station 41, the second reversing fixture 2332 in the defective product reversing assembly 24 is set corresponding to the defective product conveying roller group 22, and the first reversing fixture 2331 in the good product reversing assembly 23 is staggered with the first reversing fixture 2331 in the defective product reversing assembly 24. The staggered arrangement can avoid the reversing fixture of the good product reversing assembly 23 from being affected by the reversing fixture of the defective product reversing assembly 24 when it rotates, and also avoid the reversing fixture of the defective product reversing assembly 24 from being affected by the reversing fixture of the good product reversing assembly 23 when it rotates. The output end of the first driving device 231 is connected to the rotating shaft 232. The first driving device 231 drives the rotating shaft 232 to rotate, thereby driving the first reversing fixture 2331 and the second reversing fixture 2332 to perform a 180° reversing motion. Under the reversing action of the first reversing fixture 2331 and the second reversing fixture 2332, the products on the feeding station 41 are reversed to the good product conveying roller group 21 or the defective product conveying roller group 22.

[0049] It is worth noting that the good product reversal assembly 23 also includes a first synchronous pulley 234, a second synchronous pulley 235 and a synchronous belt 236. The first synchronous pulley 234 is fixedly disposed on the rotating shaft 232, the output end of the first drive device 231 is provided with the second synchronous pulley 235, and the synchronous belt 236 is wound around the first synchronous pulley 234 and the second synchronous pulley 235.

[0050] Specifically, the first drive device 231 is a servo motor, which has good drive stability. The first drive device 231 drives the second synchronous pulley 235 to rotate. The synchronous belt 236 connects the first synchronous pulley 234 and the second synchronous pulley 235. The second synchronous pulley 235 drives the first synchronous pulley 234 to rotate through the synchronous belt 236. The first synchronous pulley 234 drives the rotating shaft 232 to rotate. The rotating shaft 232 drives the first reverse fixture 2331 and the second reverse fixture 2332 in the good product reverse assembly 23 to perform a 180° reverse motion. Furthermore, the defective product reversal assembly 24 has the same structure as the good product reversal assembly 23. Therefore, the working process of the defective product reversal assembly 24 is the same as that of the good product reversal assembly 23. The difference is that in the defective product reversal assembly 24, the rotating shaft 232 drives the first reversing fixture 2331 and the second reversing fixture 2332 in the defective product reversal assembly 24 to perform a 180° reversal motion. The rotation direction of the rotating shaft 232 in the defective product reversal assembly 24 is opposite to that of the rotating shaft 232 in the good product reversal assembly 23, thereby realizing the reversal of the product from the feeding station 41 to the good product conveying roller group 21 or the defective product conveying roller group 22.

[0051] To further explain, the good product conveying roller group 21 includes multiple good product conveying rollers 212 rotatably mounted on the frame 1. The multiple good product conveying rollers 212 are arranged sequentially at intervals along the front-back direction. The second reversing fixture 2332 in the good product reversing assembly 23 is located above the gap between two good product conveying rollers 212.

[0052] The defective product conveying roller group 22 includes multiple defective product conveying rollers 222 rotatably mounted on the frame 1. The multiple defective product conveying rollers 222 are arranged sequentially at intervals in the front-back direction. The second reversing fixture 2332 in the defective product reversing assembly 24 is located above the gap between two defective product conveying rollers 222.

[0053] The reversing mechanism 2 also includes a plurality of feeding support frames 25 disposed on the frame 1. The feeding support frames 25 are spaced apart in the front-back direction. The first reversing fixture 2331 is located in the gap between two of the feeding support frames 25, and the first reversing fixture 2331 is located below the horizontal plane where the top surface of the feeding support frame 25 is located.

[0054] The first reversing fixture 2331 and the second reversing fixture 2332, which are located away from the rotating shaft 232, are respectively provided with a return hook 2333.

[0055] It is worth noting that the intervals between the good product conveying roller 212 and the defective product conveying roller 222 are to leave gaps for the reversing fixture to pass through during reversal. Furthermore, clearance grooves can be provided on the worktable of the frame 1 at the positions corresponding to the positions of the first reversing fixture 2331 and the second reversing fixture 2332 to allow them to pass through.

[0056] Furthermore, it also includes a roller conveyor cover 28, which is fixedly disposed on the upper surface of the frame 1. One end of the good product conveyor roller 212 and one end of the defective product conveyor roller 222 are respectively disposed inside the corresponding roller conveyor cover 28.

[0057] Specifically, the good product conveying roller 212 and the defective product conveying roller 222 can be connected to the second drive device 211 via a synchronous pulley and a synchronous belt to realize the rolling drive of the good product conveying roller 212 and the defective product conveying roller 222, thereby realizing the automated transportation of good and defective products. The second drive device 211 can be a motor.

[0058] In addition, the first reversing fixture 2331 and the second reversing fixture 2332 are provided with a back hook 2333, which can effectively prevent the product from being thrown out or falling during reversal.

[0059] Furthermore, the reversing mechanism 2 also includes a feed baffle 26 and a discharge baffle 27. The feed baffle 26 is located on the side of the feed station 41 away from the feed conveyor belt 4. The discharge baffle 27 is located on the side of the good product conveyor roller group 21 away from the good product conveyor belt 5, and the discharge baffle 27 is located on the side of the defective product conveyor roller group 22 away from the defective product conveyor belt 6.

[0060] By setting the feed baffle 26 on the side of the feed station 41 away from the feed conveyor belt 4, the product entering the feed station 41 can be effectively prevented from falling off from the other side of the feed direction of the feed station 41. Similarly, by setting the discharge baffle 27 on the side away from the good product conveyor belt 5, the product can be effectively prevented from falling off due to the rolling of the good product conveyor roller 212 after entering the good product conveyor roller group 21. Likewise, by setting the discharge baffle 27 on the side of the defective product conveyor belt 6, the product can be effectively prevented from falling off due to the rolling of the defective product conveyor roller 222 after entering the defective product conveyor roller group 22.

[0061] Furthermore, it also includes a through-beam mechanism 31, which is disposed between the feeding station 41 and the feeding conveyor belt 4. The through-beam mechanism 31 includes a through-beam sensor 311 and a base 312 disposed opposite to each other. The base 312 is fixedly disposed on the upper surface of the frame 1, and the through-beam sensor 311 is disposed on the base 312.

[0062] Preferably, by setting the through-beam sensor 311, when a product enters the reversing mechanism 2, the through-beam sensor 311 uses through-beam light to determine whether there is an obstruction in the reversing mechanism 2. When a product passes by, the through-beam mechanism 31 sends a signal that the product has entered, and the vision inspection mechanism 3 begins to acquire images of the product, thereby performing the detection and judgment work of the vision inspection reversing device on the product. The reversing mechanism 2 reverses according to the judgment of the vision inspection mechanism 3. If the product is judged to be a good product, it is reversed to the good product conveying roller group 21; if the product is judged to be a defective product, it is reversed to the defective product conveying roller group 22, thereby realizing fully automatic detection and screening.

[0063] To further explain, the visual inspection mechanism 3 includes an image acquisition component 32, a visual multi-axis adjustment component 33, and a visual gantry 34. The visual gantry 34 is fixedly mounted on the frame 1, and the visual multi-axis adjustment component 33 is mounted on the frame 1. The image acquisition component 32 is connected to the movable end of the visual multi-axis adjustment component 33, and the visual multi-axis adjustment component 33 is used to adjust the position of the image acquisition component 32.

[0064] Specifically, when the visual inspection reversing device is working, when the product enters the feeding station 41 from the feeding conveyor belt 4, the photoelectric mechanism 31 sends a signal that the product has entered. The image acquisition component 32 is adjusted in position on the visual gantry 34 by the vision multi-axis adjustment component 33, so that the image acquisition component 32 can be aligned with the product, thereby better detecting and judging the product, and directly performing visual inspection and sorting on the finished products.

[0065] Specifically, the visual multi-axis adjustment assembly 33 includes a first slide rail 331, a first slider 332, a second slide rail 333, a second slider 334, a third slide rail 335, a third slider 336, and a plurality of bolts 337;

[0066] The first slide rail 331 is disposed on the visual gantry 34 in the front-back direction, and the first slider 332 is slidably disposed on the first slide rail 331 in the front-back direction;

[0067] The second slide rail 333 is fixedly connected to the first slider 332. The second slide rail 333 is arranged in the left and right direction, and the second slider 334 is slidably arranged on the second slide rail 333 in the left and right direction.

[0068] The third slide rail 335 is fixedly connected to the second slider 334. The third slide rail 335 is arranged in the vertical direction, and the third slider 336 is slidably arranged on the third slide rail 335 in the vertical direction.

[0069] The sidewalls of the first slider 332, the second slider 334, and the third slider 336 are respectively provided with mounting holes 338, and the bolts 337 are respectively tightened into the corresponding mounting holes 338.

[0070] The visual multi-axis adjustment component 33 adjusts the moving direction and position of the image acquisition component 32 by setting multiple slide rails, multiple sliders and multiple bolts. After the image acquisition component 32 is adjusted to a suitable position by the slide rails and sliders, the bolts 337 are tightened. The bolts 337 are used to fix the position of the corresponding sliders, so as to realize the range adjustment of the visual acquisition depth of the visual inspection reversal device. It is more convenient, efficient and accurate than the screw-fixed and clamp-fixed devices on the market in the past, and is not affected by equipment vibration or other factors.

[0071] It is worth noting that the image acquisition component 32 includes an industrial camera 321, an industrial lens 322, a vision light source 323, and a lifting and sliding base 324;

[0072] The industrial lens 322 is mounted on the industrial camera 321, the industrial camera 321 is mounted on the lifting sliding base 324, and there are two third sliders 336. The lifting sliding base 324 is fixedly connected to the upper third slider 336.

[0073] The visual light source 323 is fixedly connected to the third slider 336 located below.

[0074] Preferably, the lifting sliding seat 324 is an L-shaped sliding seat, which is fixedly mounted on the third slider 336. The third slider 336 slides up and down on the third slide rail 335, thereby driving the industrial camera 321 and the industrial lens 322 to move in the vertical direction to inspect the upper surface of the product. In addition, the vision light source 323, which is fixedly connected to the third slider 336 located below, can move up and down on the third slide rail 335.

[0075] The visual light source 323 is used to illuminate the target and improve brightness, which is beneficial for the industrial camera 321 to capture images. It can also overcome ambient light interference and ensure image stability. Through appropriate light source design, the target information and background information in the image can be optimally separated, which can greatly reduce the difficulty of image recognition. At the same time, it can improve the positioning and measurement accuracy of the visual inspection mechanism 3, thereby improving the reliability and overall performance of the visual inspection mechanism 3. Specifically, the visual inspection reversal device can be used to detect whether a part is missing after product demolding, or it can be used as the back end of a cartoning machine to detect whether the box coding is normal and to identify coding information. It is mostly used in paper boxes to identify their coding, characters, etc., and has a wider range of applications.

[0076] Preferably, the visual inspection reversal device further includes an industrial control computer. The through-beam sensor 311, the second drive device 211 of the good product conveying roller group 21, the second drive device 211 of the defective product conveying roller group 22, the industrial camera 321, the first drive device 231 of the good product reversal assembly 23, and the first drive device 231 of the defective product reversal assembly 24 are respectively communicatively connected to the industrial control computer. When a product enters the feeding station 41, the through-beam sensor 311 of the through-beam mechanism 31 detects the product and sends a signal indicating that the product has entered to the industrial control computer. The industrial control computer then sends an image acquisition signal based on the product entry signal. The command is given to the industrial camera 321, which acquires images of the product and sends the acquired images to the industrial control computer for detection and judgment. If the product is judged to be good, the industrial control computer controls the first drive device 231 of the good product reversal component 23 to drive the rotating shaft 232 of the good product reversal component 23 to rotate, and the product will be reversed by the good product reversal component 23 to the good product conveyor roller group 21. If the product is judged to be defective, the industrial control computer controls the first drive device 231 of the defective product reversal component 24 to drive the rotating shaft 232 of the defective product reversal component 24 to rotate, and the product will be reversed to the defective product conveyor roller group 22. The visual inspection reversal equipment only requires one operator to run the entire line, and can realize online automated production visual inspection and fully automatic inspection and screening. The equipment structure is simple.

[0077] To further explain, it also includes a display 35 and an alarm light 36, which are respectively fixedly mounted on the visual gantry 34, and the alarm light 36 is equipped with a buzzer inside.

[0078] The display 35 clearly shows the image acquisition of the product on the feeding station 41 by the vision inspection mechanism 3 and the feedback on the product inspection. In addition, the status feedback of the mechanical parts in the vision inspection reversal device can also be seen.

[0079] The alarm light 36 is configured to alert the operator when the visual inspection reversal device is working.
