Description

Technical Field

[0001] This invention relates to the field of appearance inspection technology, and in particular to a batch appearance inspection system. Background Technology

[0002] After production is completed, products typically undergo quality checks using an appearance inspection system to ensure they meet standards and are approved for shipment. Existing appearance inspection systems generally include a turntable mechanism, and a loading mechanism, an inspection mechanism, and an unloading mechanism arranged sequentially along its circumference. The loading mechanism transports the products to be inspected one by one to a carrier on the turntable mechanism. The turntable mechanism then carries the products sequentially through the inspection mechanisms for testing, finally reaching the unloading mechanism, where the unloading mechanism removes the products from the carrier.

[0003] However, when a single carrier carries multiple products simultaneously, the unloading mechanism must separate qualified and unqualified products to their respective storage areas based on the inspection results. This sorting process significantly slows down the unloading cycle time, thus limiting the overall inspection efficiency of the system. Furthermore, the presence of unqualified products after inspection results in a discrepancy between the number of products entering the inspection system and the number of qualified products ultimately leaving, causing inconvenience for subsequent statistics and sorting work.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a batch appearance inspection system that has high inspection efficiency and can ensure that the number of qualified products leaving the system is consistent with the number of products entering the system.

[0006] The objective of this invention is achieved through the following technical solution: a batch appearance inspection system, comprising:

[0007] A turntable mechanism includes a turntable and a plurality of carriers disposed on the turntable, each carrier being configured to simultaneously carry a plurality of products;

The second substrate has a second clearance hole formed through it in the vertical direction. The material feeding cylinder is fixed to the lower end face of the second substrate and corresponds to the second clearance hole.

[0026] A cutting assembly includes a cutting plate and a cutting cylinder. The cutting plate is arranged parallel between the first substrate and the second substrate. The cutting plate has a cutting hole formed through it in the vertical direction. The cutting plate responds to the driving of the cutting cylinder so that the cutting hole is in contact with the storage cylinder or the dropping cylinder.

[0027] The projections of the storage cylinder and the discharge cylinder in the vertical direction do not overlap. Only when the cutting hole is in contact with the storage cylinder is a single product in the storage cylinder suitable for falling into the cutting hole and being supported on the second substrate.

[0043] The baffle is located above the waste collection box and is disposed on one side of the waste collection box in the pulling direction of the pull-out assembly. The enclosure frame is located at the material release position of the first feeding mechanism.

[0050] A replenishment robot is adapted to grasp the product from the replenishment bin and transfer it to the replenishment location;

[0051] The receiving bin is adapted to move from the feeding position of the second feeding mechanism to the feeding position of the feeding mechanism under the drive of the second rotating module.

[0052] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts the above-mentioned structure, and uses independent first and second feeding mechanisms to feed non-conforming products and qualified products respectively, avoiding the cycle bottleneck caused by the need for identification and sorting of a single feeding mechanism, thereby greatly improving the efficiency and smoothness of the overall detection process; by setting up a replenishment mechanism, the replenishment mechanism can automatically replenish the qualified product area with the corresponding number of qualified products according to the number of non-conforming products detected in real time. This makes the number of qualified products output from the system constant and forms a clear correspondence with the feeding quantity, which greatly facilitates subsequent production statistics, packaging and logistics sorting, and improves the level of precision in production management.

Detailed Implementation

[0069] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and not for limiting the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0070] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0071] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0072] Please see Figure 1 and Figure 2 As shown, a batch appearance inspection system corresponding to a preferred embodiment of the present invention includes: a turntable mechanism 100, including a turntable 110 and a plurality of carriers 120 disposed on the turntable 110, each carrier 120 being configured to simultaneously carry a plurality of products; a loading mechanism 200 for loading products onto the carriers 120; at least one inspection mechanism 300 for inspecting the appearance of the products; a first unloading mechanism 400 for unloading products that fail inspection into a defective product area; a second unloading mechanism 500 for unloading products that pass inspection into a qualified product area; and a replenishment mechanism 600 for replenishing a corresponding number of qualified products into the qualified product area according to the number of defective products detected; wherein the loading mechanism 200, the inspection mechanism 300, the first unloading mechanism 400, and the second unloading mechanism 500 are all located on the flow path of the turntable 110 and are arranged sequentially along the circumference of the turntable 110.

[0073] This invention employs the aforementioned structure, using independent first feeding mechanism 400 and second feeding mechanism 500 to feed non-conforming and conforming products respectively. This avoids the cycle time bottleneck caused by the need for identification and sorting in a single feeding mechanism, thereby significantly improving the efficiency and smoothness of the overall inspection process. By setting up a replenishment mechanism 600, the replenishment mechanism 600 can automatically replenish the conforming product area with a corresponding number of conforming products based on the number of non-conforming products detected in real time. This ensures that the number of conforming products output from the system remains constant and forms a clear correspondence with the number of products fed in, greatly facilitating subsequent production statistics, packaging, and logistics sorting, and improving the level of precision in production management.

[0074] Furthermore, in this embodiment, the testing mechanism 300 includes a first testing mechanism 310 and a second testing mechanism 320. The first testing mechanism 310 is used to test the size of the product, and the second testing mechanism 320 is used to test the shape of the product. Admittedly, in other embodiments, adaptive adjustments can be made according to actual needs, which will not be elaborated here.

[0075] Furthermore, the turntable 110 is provided with a loading station, a first inspection station, a second inspection station, a first unloading station, and a second unloading station in sequence along its circumference. The turntable 110 is adapted to drive each carrier 120 to flow through the above-mentioned stations in sequence. The loading mechanism 200 is located at the loading station, the first inspection mechanism 310 is located at the first inspection station, the second inspection mechanism 320 is located at the second inspection station, the first unloading mechanism 400 is located at the first unloading station, and the second unloading mechanism 500 is located at the second unloading station.

[0076] Furthermore, the turntable 110 includes a turntable body 111 and a frame 112. A drive structure is provided in the middle of the turntable body 111 to drive its rotation. The frame 112 is connected to the periphery of the turntable body 111, and multiple frames are evenly distributed along the circumference of the turntable body 111. The frame 112 has a through structure in the vertical direction. The carrier 120 is made of a transparent material, such as high-transparency glass, and corresponds one-to-one with the frame 112 and is fixedly embedded in the frame 112.

[0077] In this embodiment, the frame 112 is integrally formed with the turntable body 111 to improve overall strength and simplify assembly. Preferably, the outer contour of the turntable body 111 is polygonal, and the number of its sides is the same as the number of each workstation; that is, in this embodiment, the outer contour of the turntable body 111 is pentagonal. The frame 112 is a square frame adapted to the sides of the turntable body 111, preferably a rectangular frame, with the long side of the frame 112 parallel to the corresponding side of the turntable body 111. Each frame 112 is respectively located on a different side of the turntable body 111. Using the above method, the processing and forming of the turntable body 111 and the frame 112 are very convenient.

[0078] Furthermore, the inner contour of the frame 112 is also rectangular, and the carrier 120 is a rectangular plate with an outer contour that matches it. The long side of the carrier 120 is parallel to the corresponding side of the turntable body 111. Each carrier 120 has multiple limiting members 121 on its bearing surface. The limiting members 121 are arranged in at least one row along the short side of the carrier 120, and each row includes multiple limiting members 121 spaced apart along the long side of the carrier 120. Each product is correspondingly limited by the limiting member 121.

[0079] By adopting the above-described structure, the carrier 120 can make better use of its space, making the limiting members 121 more orderly and compact. In this embodiment, the product is an annular body with an opening in the middle, and the limiting member 121 is a positioning pin that matches the opening of the product. The product is sleeved on the limiting member 121 and supported on the bearing surface of the carrier 120.

[0080] Preferably, an ion gun 130 is provided on the turntable body 111. There are multiple ion guns 130, which are located on different sides of the turntable body 111. The air outlet side of the ion gun 130 faces the carrier 120 so as to blow air and remove dust from the products on the carrier 120.

[0081] Furthermore, referring to Figures 3 to 6 As shown, the feeding mechanism 200 includes a first support 210, a storage assembly 220, a dropping assembly 230, and a cutting assembly 240. The storage assembly 220 includes a first substrate 221 and a storage cylinder 222. The first substrate 221 is fixedly connected to the first support 210 and has a first clearance hole 2211 extending vertically through it. The storage cylinder 222 is a cylinder extending vertically through it, used to store several stacked products. The storage cylinder 222 is fixed to the upper end face of the first substrate 221 and corresponds to the first clearance hole 2211.

[0082] The storage cylinder 222 and the first substrate 221 can be integrally formed or separately formed and then assembled together. In this embodiment, the storage cylinder 222 and the first substrate 221 are separately formed and then assembled together. The storage cylinder 222 is partially embedded in the first clearance hole 2211, and its bottom does not protrude relative to the first clearance hole 2211, preferably being flush with it. The inner diameter of the storage cylinder 222 is slightly larger than the outer diameter of the product to ensure that the product can fall smoothly. Operators or automated structures can put the product into the storage cylinder 222 from the top, and the product can fall out of the storage cylinder 222 from the bottom.

[0083] The feeding assembly 230 is located below the storage assembly 220 and includes a second substrate 231 and a feeding cylinder 232. The second substrate 231 is disposed parallel to the first substrate 221 below it and is fixed to the first substrate 221 by a connector 233. The second substrate 231 has a second clearance hole 2311 formed through it in the vertical direction. The feeding cylinder 232 is fixed to the lower end face of the second substrate 231 and corresponds to the second clearance hole 2311.

[0084] The feeding cylinder 232 and the second substrate 231 can be integrally formed or separately formed and then assembled together. In this embodiment, integral forming is preferred. The inner hole of the feeding cylinder 232 is coaxial with the second clearance hole 2311, and their inner diameters are the same as the inner diameter of the storage cylinder 222. The product can enter the feeding cylinder 232 from the upper end face of the second substrate 231 through the second clearance hole 2311 and fall out from the bottom of the feeding cylinder 232.

[0085] The cutting assembly 240 includes a cutting plate 241 and a cutting cylinder 242. The cutting plate 241 is disposed parallel to the first substrate 221 and the second substrate 231. The upper end surface of the cutting plate 241 can be in contact with the lower end surface of the first substrate 221 or have a certain gap, which is not greater than the thickness of the product. The lower end surface of the cutting plate 241 can be in contact with the upper end surface of the second substrate 231 or have a certain gap, which is not greater than the thickness of the product. The cutting plate 241 has a cutting hole 2411 formed through it in the vertical direction. The cutting cylinder 242 is disposed on the upper end surface of the first substrate 221 and is drivenly connected to the cutting plate 241. The driving direction of the cutting cylinder 242 is parallel to the width direction of the carrier 120 located at the loading station. The projections of the storage cylinder 222 and the discharge cylinder 232 in the vertical direction do not coincide. The cutting plate 241 responds to the drive of the cutting cylinder 242 to make the cutting hole 2411 align with either the storage cylinder 222 or the discharge cylinder 232. Only when the cutting hole 2411 aligns with the storage cylinder 222 is a single product in the storage cylinder 222 suitable for falling into the cutting hole 2411 and being supported on the second substrate 231. Only when the cutting hole 2411 aligns with the discharge cylinder 232 is a product in the cutting hole 2411 suitable for falling into the carrier 120 via the discharge cylinder 232.

[0086] Specifically, when the cutting hole 2411 is aligned with the storage cylinder 222, a single product falls into the cutting hole 2411 and is blocked by the second substrate 231. When the cutting hole 2411 is not aligned with the storage cylinder 222, the cutting plate 241 can block the storage cylinder 222 and allow the product to fall into the discharge cylinder 232 when the cutting hole 2411 is aligned with the discharge cylinder 232.

[0087] In this embodiment, there are multiple storage cylinders 222, arranged side by side at intervals. The arrangement direction of the storage cylinders 222 is parallel to the length direction of the carrier 120 located at the loading station, and their number is the same as the number of limiting members 121 in each row. Each storage cylinder 222 is provided with two dropping cylinders 232 and two cutting holes 2411 below it. The two dropping cylinders 232 and the two cutting holes 2411 are arranged at intervals along the width direction of the carrier 120 located at the loading station.

[0088] A slide rail structure is provided on the first substrate 221 or the second substrate 231, and the cutting plate 241 is connected to the slide rail structure to facilitate reciprocating movement between a first position and a second position along the width direction of the carrier 120 at the loading station. When the cutting plate 241 is in the first position, one cutting hole 2411 corresponds to the storage cylinder 222, and the other cutting hole 2411 is connected to one of the dropping cylinders 232. When the cutting plate 241 is in the second position, one cutting hole 2411 corresponds to the storage cylinder 222, and the other cutting hole 2411 corresponds to the other dropping cylinder 232.

[0089] Using the above method, when the cutting plate 241 moves to the first position, it can cause a row of products arranged along the length of the carrier 120 at the loading station to fall into the carrier 120. When the cutting plate 241 moves to the second position, it can cause another row of products arranged along the length of the carrier 120 to fall into the carrier 120. Accordingly, in this embodiment, there are two rows of limiting members 121 on the carrier 120, and each limiting member 121 at the loading station is located directly below the dropping cylinder 232.

[0090] Since the inner diameter of the discharge cylinder 232 is usually slightly larger than the outer diameter of the product, as the product gradually falls, it tends to tilt when it is in the discharge cylinder 232, making it difficult for the discharged product to be reliably fitted onto the limiting member 121. Preferably, the feeding mechanism 200 also includes a distributing component 250 and an air blowing component. The distributing component 250 is disposed on the storage component 220 and includes a distributing plate 251 and a distributing cylinder 252. The distributing plate 251 is located below the discharge cylinder 232 and is connected to the first base plate 221 or the second base plate 231 via a slide rail structure. The sliding direction of the distributing plate 251 is the same as the sliding direction of the cutting plate 241. The distributing cylinder 252 is disposed on the upper end face of the first base plate 221 and is drivenly connected to the distributing plate 251. The distributing plate 251 responds to the drive of the distributing cylinder 252 to block or release the bottom of each discharge cylinder 232. Specifically, the dispensing cylinder 252 can allow the product to flow out of the discharge cylinder 232 by moving the dispensing plate 251 away from directly below the discharge cylinder 232, and / or the dispensing plate 251 can also be provided with openings that allow the product to pass through, thereby reducing the travel of the dispensing plate 251 and improving the reliability during the movement process.

[0091] An air blowing assembly is disposed on the first substrate 221 and is adapted to blow airflow downward from the top of the discharge cylinder 232 into the discharge cylinder 232. The air blowing assembly includes a plurality of air nozzles 260 corresponding one-to-one with the discharge cylinder 232. Before the product is loaded onto the carrier 120, the dividing plate 251 first blocks each discharge cylinder 232, so that the product cut by the cutting plate 241 remains in the discharge cylinder 232. Then the air nozzles 260 blow air into the discharge cylinder 232, so that the misaligned product is corrected and falls onto the dividing plate 251. Then the dividing plate 251 moves away from the discharge cylinder 232, and the product is reliably discharged and sleeved on the limiting member 121.

[0092] Furthermore, referring to Figure 7 As shown, the first inspection mechanism 310 includes a first inspection frame 311 and a laser assembly 312 disposed on the first inspection frame 311. The laser assembly 312 is located above the turntable 110, with its imaging end facing downwards. The turntable body 111 is adapted to drive the frame 112 to flow directly below the laser assembly 312, enabling the laser assembly 312 to photograph each product at the carrier 120 on the frame 112. The laser assembly 312 includes at least one 3D camera 3121. In this embodiment, multiple cameras are arranged side by side, with their arrangement direction parallel to the length direction of the carrier 120 located at the first inspection station. Each 3D camera 3121 corresponds one-to-one with a product at a single row of limiting members 121, so as to reliably photograph each product. In addition, the first inspection mechanism 310 also includes a first transverse module 313 that is connected between the first inspection frame 311 and the laser assembly 312. The first transverse module 313 is a linear module, and its driving direction is parallel to the width direction of the carrier 120 located at the first inspection station. When the limiting member 121 has multiple rows, the first transverse module 313 can drive the laser assembly 312 to move to different rows of products.

[0093] Furthermore, referring to Figure 8 As shown, the second inspection mechanism 320 includes a second inspection frame 321, an upper camera assembly 322 and a lower camera assembly 323 mounted on the second inspection frame 321. The upper camera assembly 322 is located above the turntable 110 with its shooting end facing downwards, and the lower camera assembly 323 is located below the turntable 110 with its shooting end facing upwards. When the carrier 120 is in the second inspection station, it is positioned between the upper camera assembly 322 and the lower camera assembly 323. Since the carrier 120 is made of transparent material, the upper camera assembly 322 and the lower camera assembly 323 can reliably acquire the shape of the upper and lower sides of the product. Preferably, each upper camera assembly 322 and lower camera assembly 323 includes multiple shape cameras 324 arranged side by side, with each shape camera 324 corresponding to a product.

[0094] Furthermore, referring to Figure 9As shown, the first unloading mechanism 400 and the second unloading mechanism 500 have the same structure. Taking the first unloading mechanism 400 as an example, the first unloading mechanism 400 includes a second support 410, a first rotating module 420, and a pick-and-place module 430. The first rotating module 420 is a rotary motor, which is mounted on the second support 410. The output of the first rotating module 420 is provided with a mounting plate 421. The pick-and-place module 430 is mounted on the mounting plate 421 and includes multiple suction nozzle assemblies 431. The pick-and-place module 430 rotates to the picking position corresponding to the carrier 120 in response to the drive of the first rotating module 420, so that the multiple suction nozzle assemblies 431 correspond one-to-one with the products on the carrier 120 at the first unloading station. Each suction nozzle assembly 431 includes a first lifting cylinder 4311 and a first suction nozzle component 4312. The first lifting cylinder 4311 is mounted on the mounting plate 421, and the first suction nozzle component 4312 is connected to the first lifting cylinder 4311. The first suction nozzle component 4312 is adapted to suck up the product downward and lift the product upward away from the carrier 120 under the drive of the first lifting cylinder 4311. The pick-up and drop module 430 with the product sucked up is adapted to rotate to the discharge position under the drive of the first rotating module 420 so as to drop the product into the non-conforming product area.

[0095] Preferably, in this embodiment, there are two pick-up and place-up modules 430. When the first rotating module 420 drives one of the pick-up and place-up modules 430 to rotate to the pick-up position, the other pick-up and place-up module 430 is in the place-up position, so that the first unloading mechanism 400 can pick up and unload materials at the same time, thereby improving the unloading efficiency.

[0096] Furthermore, referring to Figure 1 , Figure 10 and Figure 11 As shown, the batch appearance system includes a first receiving mechanism 700 located in the non-conforming product area. The first receiving mechanism 700 is used to collect non-conforming products discharged by the first unloading mechanism 400. The first receiving mechanism 700 includes a pull-out assembly 710, a guide frame 720, a baffle 730, and a enclosure frame 740.

[0097] The pull-out assembly 710 includes a guide rail 711, a slider 712, and a tray 713. The length direction of the guide rail 711 is parallel to the width direction of the carrier 120 located at the first unloading station. The slider 712 is slidably connected to the guide rail 711, and the tray 713 is fixedly connected to the slider 712. A waste collection box 716 for collecting defective products is placed on the tray 713. The tray 713 is provided with a stop 714 for limiting the waste collection box 716 and a handle 715 for the operator to apply a pulling force.

[0098] A guide frame 720 is mounted above the pull-out assembly 710. A baffle 730 is mounted on the guide frame 720 and can slide relative to the guide frame 720. The sliding direction of the baffle 730 is parallel to the sliding direction of the support plate 713. The baffle 730 is fixedly connected to the support plate 713 so that it slides synchronously with the support plate 713. The baffle 730 is located above the waste collection box 716 and is located on one side of the waste collection box 716 in the pull-out direction of the pull-out assembly 710. A containment frame 740 is located at the material release position of the first unloading mechanism 400. It is fixed on the guide frame 720 and placed on top of the baffle 730. The containment frame 740 has a through structure in the vertical direction. The pull-out assembly 710 is adapted to move the waste collection box 716 directly under the enclosure frame 740 under external force, or to move away from the enclosure frame 740 under external force, so that the baffle 730 is sealed under the enclosure frame 740.

[0099] By adopting the above structure, when the first receiving mechanism 700 is operating normally, the waste collection box 716 is located directly below the enclosure frame 740. When the first unloading mechanism 400 moves the product to the unloading position and releases it, the product falls through the enclosure frame 740 into the waste collection box 716. When the waste collection box 716 is full, the pull-out component 710 is pulled to move the waste collection box 716 away from directly below the enclosure frame 740 so that the operator can replace the waste collection box 716. At the same time, the baffle 730 is located directly below the enclosure frame 740 so that it can continue to receive the products unloaded by the first unloading mechanism 400. When a new waste collection box 716 is pushed back to directly below the enclosure frame 740, the product on the baffle 730 can fall into the waste collection box 716 under the obstruction of the enclosure frame 740, avoiding the need for machine downtime to replace the box.

[0100] Preferably, in order to ensure that the baffle 730 can slide smoothly, the bottom of the enclosure frame 740 does not contact the baffle 730. However, since some products are sheet-like structures with a small thickness, the enclosure frame 740 cannot reliably block the products, thus preventing the products from falling into the waste collection box 716.

[0101] Preferably, the baffle 730 is recessed inward from its top to form a clearance groove 731. The clearance groove 731 extends along the width direction of the carrier 120 at the first unloading station, and there are multiple such grooves arranged side-by-side at intervals along the length direction of the carrier 120 at the first unloading station. The enclosure frame 740 has protruding portions 741 on both sides of its bottom along the extension direction of the clearance groove 731. Multiple protrusions 741 are spaced apart along the arrangement direction of the clearance groove 731 to be received in different clearance grooves 731. During the process of pushing the waste collection box 716 directly under the enclosure frame 740, the protrusions 741 can reliably push the side of the product, causing the product to fall into the waste collection box 716. Preferably, the protrusions 741 do not contact the clearance grooves 731, improving the smoothness of the movement of the baffle 730.

[0102] Furthermore, referring to Figure 1 , Figure 12 and Figure 13 As shown, the batch appearance inspection system includes a second receiving mechanism 800 located in the qualified product area. The second receiving mechanism 800 is used to centrally collect products discharged from the second unloading mechanism 500. The second receiving mechanism 800 includes a carrier plate 810, receiving bins 820, and a second rotating module 830. The receiving bins 820 are used to receive qualified products and are disposed on the carrier plate 810, with multiple bins spaced apart circumferentially along the carrier plate 810. The second rotating module 830 is drive-connected to the carrier plate 810 and is adapted to drive the carrier plate 810 to rotate, causing different receiving bins 820 to flow to the unloading position of the second unloading mechanism 500.

[0103] The receiving bin 820 includes a base plate 821 and multiple receiving rods 822 fixed to the base plate 821. The number of receiving rods 822 is the same as the number of limiting members 121 on the carrier 120. When the product picked up by the second unloading mechanism 500 rotates to the unloading position, the product is positioned directly above the receiving rod 822. The second unloading mechanism 500 can lower the product to the top of the receiving rod 822, and then the product falls under the action of gravity and is fitted onto the outside of the receiving rod 822, and falls to its bottom along the guide rod.

[0104] In this embodiment, there are three receiving bins 820. When one of them is in the feeding position of the second feeding mechanism 500, the other two receiving bins 820 are in the feeding position and the feeding position, respectively. The feeding mechanism 600 can replenish the product to the receiving bin 820 located in the feeding position. The operator can unload the receiving bin 820 that is full of products at the feeding position.

[0105] Furthermore, referring to Figure 14 As shown, the replenishment mechanism 600 includes a replenishment bin 610 and a replenishment robot 620. The replenishment bin 610 contains qualified products, and the replenishment robot 620 is adapted to grab the products from the replenishment bin 610 and transfer them to the replenishment position to place the products into the receiving rod 822 which is short of a certain number.

[0106] Specifically, after the second feeding mechanism 500 performs a preset number of feeding actions, each receiving rod 822 of the receiving bin 820 located at the feeding position is in a theoretically full-load state. Driven by the second rotating module 830, it rotates to the replenishment position. When the detection mechanism 300 detects a defective product, one or more receiving rods 822 are in a non-full-load state. At this time, the replenishment mechanism 600 replenishes the product into the corresponding receiving rod 822 according to the detection result. When each receiving rod 822 of the receiving bin 820 is in a full-load state, it rotates to the feeding position so that the operator can feed it and put the empty receiving bin 820 back into the carrier plate 810.

[0107] Furthermore, the replenishment bin 610 includes a base 611, a replenishment rod 612, and a lifting module 613. The replenishment rod 612 is fixed vertically to the base 611, and qualified products are stacked and fitted over the replenishment rod 612. The output end of the lifting module 613 is connected to a top block 6131, which is used to lift the entire stack of products under the drive of the lifting module 613, so that the top product is at a preset height for the replenishment robot 620 to pick up.

[0108] Preferably, the replenishment bin 610 further includes a guide rail assembly 614, which is connected to the base 611. By applying an external force to the base 611, it can slide along the guide rail assembly 614, causing the replenishment rod 612 to move away from the top block 6131, so that the operator can replenish the product.

[0109] The replenishing robot 620 includes a second transverse module 621, a second lifting cylinder 622 driven by the second transverse module 621, and a second suction nozzle 623 driven by the second lifting cylinder 622. The second transverse module 621 can drive the second suction nozzle 623 in two perpendicular horizontal directions. The second suction nozzle 623 is adapted to pick up the product on the top layer of the replenishing rod 612 under the drive of the second transverse module 621 and the second lifting cylinder 622, and transfer it to the receiving rod 822 where the product to be replenished is required.

[0110] The working process of the batch appearance inspection system of the present invention is as follows: The products to be inspected are placed into each storage cylinder 222. The turntable 110 drives the carrier 120 to move to the loading station. The cutting component 240 cuts the products in the storage cylinder 222 into each dropping cylinder 232, so that the products fall to different limiting members 121 respectively. The turntable 110 drives the carrier 120 carrying the products to flow through the first inspection station and the second inspection station in sequence to the first unloading station. The first unloading mechanism 400 removes the unqualified products from the carrier 120 according to the inspection results and transfers them to the first receiving mechanism 700. Then the turntable... 110 continues to move the carrier 120 to the second unloading station. The second unloading mechanism 500 removes the qualified products from the carrier 120 and transfers them to the receiving bin 820 of the second receiving mechanism 800. The carrier 120 that has removed the products continues to turn back to the loading station, thereby realizing continuous inspection. After the second unloading mechanism 500 performs the unloading action on a preset number of carriers 120, the receiving bin 820 moves to the replenishment position. The replenishment mechanism 600 replenishes the qualified products in the replenishment bin 610 to the receiving bin 820 according to the inspection results. Then the receiving bin 820 moves to the unloading position to perform unloading.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
