Description

Technical Field

[0001] This application relates to the field of components for charging stations of robotic vacuum cleaners, and in particular to a visual inspection device for conveyor belt type sealing rings. Background Technology

[0002] Thanks to advancements in modern science, humanity is entering the era of artificial intelligence and Industry 4.0. Smart homes are gradually becoming a part of people's lives, and the demand for robotic vacuum cleaners is growing. During the assembly of the charging dock's upper casing, there is a crucial step in assembling the sealing ring. The assembly of this sealing ring is extremely important for the entire charging dock. If the sealing ring is not properly assembled, dust, water, or other debris can enter the charging dock, potentially causing electrical leakage and resulting in injury or malfunction.

[0003] The visual inspection equipment in related technologies generally includes a product conveyor line, a visual inspection module separate from the product conveyor line, and a robotic arm for gripping and transferring materials. After the product to be inspected arrives, the robotic arm grips the product to be inspected and transfers it to the visual inspection module. After the inspection is completed, the robotic arm drives the inspected product to reset, thus completing one inspection cycle.

[0004] Regarding the aforementioned technical methods, the robotic arm waits for the product inspection to be completed before unloading, and can only load the product after unloading is completed. This affects the loading and unloading of products, resulting in low inspection efficiency. Summary of the Invention

[0005] To address the issue of low product inspection efficiency caused by factors affecting product loading and unloading, this application provides a visual inspection device for conveyor belt sealing rings.

[0006] This application provides a visual inspection device for conveyor belt sealing rings, which adopts the following technical solution.

[0007] A conveyor belt type sealing ring visual inspection device includes:

[0008] Frame mounting base plate;

[0009] A feeding device is mounted on the fixed base plate of the frame for continuous conveying of products to be inspected.

[0010] A mid-section connecting device is disposed in the middle of the frame fixing base plate and is correspondingly connected to the conveying end of the feeding device;

[0011] The unloading device is mounted on the fixed base plate of the frame and is connected to the conveying end of the middle connecting device. The unloading device is used to continuously convey the inspected products.

[0012] A visual inspection device is installed on the frame base plate and located above the middle connecting device. The visual inspection device is used to inspect whether the sealing ring assembled on the product is qualified.

[0013] A secondary positioning device is provided on the frame base plate and located between the conveying space of the middle connecting device. The secondary positioning device is used to drive the product to be inspected on the middle connecting device to slide towards the visual inspection device.

[0014] The secondary positioning device has a first avoidance state for avoiding the conveying of inspected products from the intermediate connecting device to the unloading device, and a second lifting state for lifting the products to be inspected from the intermediate connecting device to the vision inspection device. In the first avoidance state, the intermediate connecting device conveys the products to be inspected from the loading device and conveys the inspected products to the unloading device. In the second lifting state, the intermediate connecting device is stationary and the vision inspection device inspects the products.

[0015] By adopting the above technical solution, after the feeding device transports the product to be inspected to the intermediate connecting device, the secondary positioning device switches from the first clearance state to the second lifting state. At the same time, the intermediate connecting device stops transporting. After the visual inspection device completes the inspection in the second lifting state, the secondary positioning device switches back to the first clearance state, thereby driving the inspected product to reset. Then, the intermediate connecting device transports the inspected product to the unloading device. On the other hand, the feeding device and the unloading device are not affected by the intermediate connecting device and continue to perform the transport operation, so that the product loading and unloading can be carried out without interruption, thereby improving the overall inspection efficiency of the conveyor belt sealing ring visual inspection equipment in this application.

[0016] Optionally, the feeding device includes a feeding base plate detachably mounted to the frame base plate and a feeding conveying mechanism mounted on the feeding base plate. The intermediate connecting device includes an intermediate conveying mechanism. The feeding conveying mechanism is provided with an inspection-ready feeding end and an inspection-ready discharging end. The intermediate conveying mechanism is provided with a connecting feeding end aligned with the inspection-ready discharging end and a connecting discharging end aligned with the unloading device. The inspection-ready feeding end is used to connect with external equipment to form an automated production line.

[0017] By adopting the above technical solution, the discharge end to be inspected is aligned with the feed end, and the discharge end is aligned with the unloading device, so that the product to be inspected can be smoothly transported in the three-section transmission line; at the same time, the setting of the feed end to be inspected makes the equipment involved in this application highly expandable, and can be aligned and connected with any external equipment as needed to form a multi-section automated production line.

[0018] Optionally, the feeding and conveying mechanism is provided with a fixed feeding component and a movable feeding component. The fixed feeding component and the movable feeding component are respectively provided with a feeding limit plate, a feeding conveying belt that rotates around the feeding limit plate, and a feeding drive component that drives the feeding conveying belt to rotate. The two feeding conveying belts are used to work together to clamp the two edges of the receiving and inspection product.

[0019] By adopting the above technical solution, under the drive of the feeding drive component, two feeding conveyor belts work together to transport the product to be tested. At the same time, the feeding conveyor belts are set with feeding limit plates so that the feeding limit plates stably support the product to be tested during the transmission process, thereby improving the transmission stability of the product to be tested.

[0020] Optionally, the movable feeding component is provided with a first adjustment module, the first adjustment module including a sliding connecting block fixedly disposed at the bottom of the feeding limiting plate, a linear sliding component slidably disposed with the sliding connecting block, and an adjustment driving component for driving the sliding connecting block to slide along the direction close to or away from the fixed feeding component.

[0021] By adopting the above technical solution, the sliding connecting block is controlled to drive the movable feeding component to slide towards or away from the fixed feeding component. This allows the relative distance between the fixed feeding component and the movable feeding component to be changed according to the length or width of different products, thereby improving the product compatibility of the feeding and conveying mechanism.

[0022] Optionally, the secondary positioning device includes a lifting mechanism disposed at the bottom of the frame fixing base plate and passing through the frame fixing base plate, and a positioning mechanism disposed at the top of the lifting mechanism. The lifting mechanism is provided with a pen-shaped lifting cylinder that drives the positioning mechanism to switch states. The pen-shaped lifting cylinder is provided with sliding bushing assemblies at both ends. The bottom of the sliding bushing assembly is threaded with a flexible limiting member. The flexible limiting member is used to limit the movement distance of the positioning mechanism when switching from the first avoidance state to the second lifting state.

[0023] By adopting the above technical solution, when the product to be inspected is above the positioning mechanism, the middle-section transmission mechanism stops conveying, and the positioning mechanism switches to the second lifting state under the drive of the pen-shaped lifting cylinder, thereby moving the product to be inspected towards the visual inspection device, thus lifting the product to be inspected to the visual inspection device for qualified inspection of the sealing ring; by adjusting the extension length of the flexible limiting member, the moving distance of the positioning mechanism from the first avoidance state to the second lifting state can be controlled according to the product height, so that the positioning mechanism can accurately lift the product to be inspected to the inspection position of the visual inspection device, further improving product compatibility.

[0024] Optionally, the positioning mechanism includes a positioning mounting base plate disposed on the top of the lifting mechanism, an adjustable limiting block disposed on the top of the positioning mounting base plate, and a rubber-coated lifting rod passing through the positioning mounting base plate. The top of the rubber-coated lifting rod is provided with a rubber sleeve. Multiple rubber-coated lifting rods and adjustable limiting blocks are provided to abut against the product shape. In the second lifting state, the multiple rubber sleeves abut against the inner top wall of the product, and the multiple adjustable limiting blocks are engaged with the outer peripheral wall of the product in the second lifting state.

[0025] By adopting the above technical solution, the adjustable limit block can limit multiple degrees of freedom of the product according to the product's external dimensions, thereby further improving the product stability when the positioning mechanism drives the product to slide back and forth; on the other hand, the rubber sleeve in the rubber-coated lifting rod ensures that the inner top wall of the product is always in a flexible contact state during the lifting or resetting process, thereby protecting the outer surface of the product when the positioning mechanism drives the product to slide up and down.

[0026] Optionally, the visual inspection device includes a heightening mounting bracket, a synchronous belt adjustment mechanism disposed on the heightening mounting bracket, and a camera inspection mechanism slidably disposed on the synchronous belt adjustment mechanism. The camera inspection mechanism is used to take pictures and inspect the product sealing ring. The synchronous belt adjustment mechanism is provided with a detection drive component that drives the camera inspection mechanism to slide back and forth along the feeding device toward the unloading device.

[0027] By adopting the above technical solution, the detection drive component is controlled according to the position of the sealing ring wrapped around the charging pile to drive the camera detection mechanism to slide back and forth, thereby enabling the camera detection mechanism to take multiple pictures of the sealing ring assembled on the product at one time to detect whether the sealing ring is installed off-center, which further improves the detection efficiency.

[0028] Optionally, the camera detection mechanism includes a detection mounting motherboard disposed on the synchronous belt adjustment mechanism, a camera disposed on the detection mounting motherboard, and two sets of bar light sources fixedly disposed on the detection mounting motherboard and located below the camera, wherein the light-emitting areas of the two sets of bar light sources are symmetrically arranged with their light-emitting areas facing downwards.

[0029] By adopting the above technical solution, two sets of bar light sources are symmetrically distributed to supplement the camera, making the camera image clearer, thereby improving the accuracy and stability of the camera's image detection.

[0030] Optionally, a slide cylinder is fixedly installed at the bottom of the detection mounting motherboard, and a backlight source is installed at the top of the slide cylinder push rod. The backlight source has its light-emitting area facing upward. In the second lifting state, the backlight source and the two sets of strip light sources work together to form a supplementary lighting space for illuminating the product.

[0031] By adopting the above technical solution, after the positioning mechanism lifts the product to be inspected to the camera's detection position, the slide cylinder drives the backlight source to move away from the detection mounting motherboard and cooperate with the strip light source to form a supplementary lighting space, thereby better highlighting the outline shadow of the sealing ring to facilitate photo detection. After the detection is completed, the slide cylinder drives the backlight source to reset to avoid the positioning mechanism from resetting and moving downward.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. Higher detection efficiency. The loading and unloading devices are not affected by the intermediate connecting device and can continuously carry out loading and unloading operations, improving the efficiency of product loading and unloading, thereby improving product detection efficiency; based on the position of the sealing ring wrapped around the charging pile, the detection drive component controls the camera detection mechanism to slide back and forth along the loading and unloading path, thereby enabling the camera detection mechanism to take multiple pictures of the sealing ring assembled on the product at one time, further improving detection efficiency.

[0034] 2. Enhanced detection accuracy and stability. Multiple rubber-coated lifting rods abut against the inner top wall of the product, while multiple adjustable limit blocks press against the outer peripheral wall, thus limiting multiple degrees of freedom of the product according to its dimensions. This ensures the positioning mechanism stably drives the product's reciprocating sliding motion. Two sets of strip light sources and a backlight simultaneously illuminate the camera, resulting in clearer imaging and improved accuracy and stability of camera-based detection.

[0035] 3. Enhanced product compatibility. By controlling the sliding connecting block to move the movable feeding component closer to or further away from the fixed feeding component, the relative distance between the fixed and movable feeding components can be adjusted according to the length or width of different products, thereby improving the product compatibility of the feeding and conveying mechanism. By adjusting the extension length of the flexible limiting component, the movement distance of the positioning mechanism from the first avoidance state to the second lifting state can be controlled according to the product height, further improving product compatibility.

[0050] The present application will be further described in detail below with reference to the accompanying drawings.

[0051] This application discloses a visual inspection device for conveyor belt type sealing rings. (Refer to...) Figure 1 and Figure 2 A conveyor belt type sealing ring visual inspection device includes a main frame 700 for installing various electrical components and a control host, and a frame fixing base plate 100 disposed within the main frame 700. The frame fixing base plate 100 is provided with a feeding device 200 for continuously conveying the products to be inspected, a middle section connecting device 300 connected to the right end of the feeding device 200, a secondary positioning device 500 disposed in the conveying space of the middle section connecting device 300, a visual inspection device 600 for detecting whether the sealing rings assembled on the products are qualified, and a device 600 connected to the right end of the middle section connecting device 300. The unloading device 400, which is connected to and continuously transports the inspected products, is connected to the secondary positioning device 500. The secondary positioning device 500 has a first avoidance state for transporting the inspected products on the intermediate connecting device 300 to the unloading device 400 and a second lifting state for lifting the products to be inspected on the intermediate connecting device 300 to the visual inspection device 600. In the first avoidance state, the intermediate connecting device 300 transports the products to be inspected from the loading device 200 and transports the inspected products to the unloading device 400. In the second lifting state, the intermediate connecting device 300 is stationary and the visual inspection device 600 inspects the products. After the feeding device 200 conveys the product to be inspected to the intermediate connecting device 300, the secondary positioning device 500 switches from the first clearance state to the second lifting state. At the same time, the intermediate connecting device 300 stops conveying. After the vision inspection device 600 completes the inspection in the second lifting state, the secondary positioning device 500 switches back to the first clearance state, thereby driving the product to reset. Then, the intermediate connecting device 300 conveys the inspected product to the unloading device 400 while conveying the product to be inspected that was conveyed by the feeding device 200. On the other hand, the feeding device 200 and the unloading device 400 are not affected by the intermediate connecting device 300, so they can continuously carry out the conveying action, which allows for uninterrupted product loading and unloading, thereby improving the overall inspection efficiency of the conveyor belt sealing ring vision inspection equipment in this application.

[0052] Refer to 2 and Figure 3 The feeding device 200 includes a feeding base plate 210 detachably mounted to the frame base plate 100 and a feeding conveying mechanism 220 mounted on the feeding base plate 210. The feeding conveying mechanism 220 is provided with an inspection-ready inlet end 221 and an inspection-ready outlet end 222. The intermediate connecting device 300 includes an intermediate conveying mechanism 310, which is provided with a connecting inlet end 311 and a connecting outlet end 312. The unloading device 400 includes an unloading base plate 43. The system includes a feeding conveyor 410 mounted on a feeding base plate 430. The feeding conveyor 410 has an inspection-complete feeding end 411 and an inspection-complete discharging end 412. The feeding end 311 is aligned with the discharge end 222 to be inspected, and the discharge end 312 is aligned with the inspection-complete feeding end 411. The feeding conveyor 220, the intermediate conveyor 310, and the discharging conveyor 410 are aligned, thus forming a three-section conveyor line for smooth product transport. The inspection-complete feeding end 221 and the inspection-complete discharging end 412 are used to connect with external equipment to form an automated production line. This makes the conveyor belt type sealing ring visual inspection equipment involved in this application highly expandable, and it can be aligned and connected with any external equipment as needed to form a multi-section automated production line.

[0053] Refer to 2 and Figure 3 The feeding and conveying mechanism 220 is provided with a fixed feeding component 223 fixedly mounted on the feeding base plate 210 and a movable feeding component 224 slidably mounted on the feeding base plate 210. The fixed feeding component 223 and the movable feeding component 224 are respectively provided with a feeding limit plate 2241, a feeding conveying belt that rotates around the feeding limit plate 2241, and a feeding drive component 2242 that drives the feeding conveying belt to rotate. The two feeding conveying belts are used to work together to clamp the two edges of the product to be inspected, and the feeding limit plate 2241 supports the product, thereby realizing the stable transmission of the product to be inspected. The movable feeding component 224 is provided with a first adjustment module 225. The first adjustment module 225 includes a sliding connecting block 2261 fixedly disposed at the bottom of the feeding limit plate 2241, a linear sliding component 226 slidably disposed with the sliding connecting block 2261, and an adjustment drive component 227 that drives the sliding connecting block 2261 to slide in a direction closer to or away from the fixed feeding component 223. This allows the movable feeding component 224 to slide in a direction closer to or away from the fixed feeding component 223 by driving the sliding connecting block 2261 according to the length or width of different products. This also improves the product compatibility of the feeding and conveying mechanism 220.

[0054] Reference Figure 3The feeding base plate 210 is also provided with a first dynamic limiting component 230 located at the discharge end 222 to be inspected. The first dynamic limiting component 230 includes a blocking cylinder located at the connection between the feeding base plate 210 and the frame fixing base plate 100, and a sensor located on the side of the blocking cylinder away from the frame fixing base plate 100. The sensor is used to detect the position of the product to be inspected that is closest to the feed end 311. A baffle is provided at the top of the blocking cylinder. In the second lifting state, the blocking cylinder drives the baffle to move away from the feeding base plate 210, thereby blocking the movement of the product to be inspected from the feed end 221 to the discharge end 222 to be inspected. When the sensor detects that the product to be tested has been conveyed to the discharge end 222, the sensor sends a signal to the blocking cylinder, which causes the blocking cylinder to move the baffle away from the feeding bottom plate 210, thereby blocking and limiting the product to be tested that has passed the sensor, so that it will not be conveyed into the middle transmission mechanism 310 in the second lifting state. This improves the problem of interference between the tested product and the product to be tested, which affects the testing efficiency and accuracy.

[0055] To further clarify, refer to Figure 3 The intermediate conveying mechanism 310 and the unloading conveying mechanism 410 have the same structure as the loading conveying mechanism 220. The intermediate conveying mechanism 310 includes a fixed intermediate component 313 fixedly mounted on the frame fixed base plate 100 and a movable intermediate component 314 slidably mounted on the frame fixed base plate 100. The movable intermediate component 314 is provided with a second adjustment module 315. The frame fixed base plate 100 is also provided with a second dynamic limiting component 320 located at the connection outlet end 312. The second dynamic limiting component 320 is used to limit the material reaching the outlet end 312. The product to be inspected above the secondary positioning device 500 is blocked and limited; the unloading and conveying mechanism 410 includes a fixed unloading component 413 fixedly mounted on the unloading base plate 430 and a movable unloading component 414 slidably mounted on the unloading base plate 430. The movable unloading component 414 is provided with a third adjustment module 415. The unloading base plate 430 is also provided with a third dynamic limiting component 420 located at the finished inspection discharge end 412. The third dynamic limiting component 420 is used to block and limit the finished inspection product that arrives at the finished inspection discharge end 412.

[0056] To further clarify, refer to Figure 3 The first adjustment module 225, the second adjustment module 315, and the third adjustment module 415 have the same structure, as shown in the reference. Figure 4Taking the first adjustment module 225 as an example, the linear sliding component 226 in the first adjustment module 225 includes two sets of linear guide sliders 2262 symmetrically fixed on the loading base plate 210 with the loading drive component 2242 as the center line. Bearing seats 2263 are provided at both ends of the guide rails, and a set of ball screw nuts 2264 are inserted through the two sets of bearing seats 2263. The nuts of the ball screw nuts 2264 are inserted and fixed on the sliding connecting block 2261. The sliding connecting block 2261 is fixed to the loading limit plate 2241 and the linear guide. Between the sliders of the rail slider 2262, the lead screw is also provided with an adjustable hollow locking block 2265, which is fixedly mounted on the sliding connecting block 2261. The adjustment drive assembly 227 includes a driving synchronous wheel 2271 and a driven synchronous wheel 2272 correspondingly mounted on the outer shaft ends of the two lead screws. The driving synchronous wheel 2271 is mounted on the left lead screw. A drive synchronous belt is wound around the driving synchronous wheel 2271 and the driven synchronous wheel 2272. A handle-type handwheel 2273 integrally connected to the left lead screw is also provided on the outside of the driving synchronous wheel 2271.

[0057] The adjustment principle of the first adjustment module 225 is as follows: the hollow diameter of the hollow locking block 2265 is adjusted so that the lead screw passing through the hollow locking block 2265 can rotate; by rotating the handle-type handwheel 2273 in the forward direction, the active synchronous wheel 2271 is rotated in the forward direction, thereby driving the driven synchronous wheel 2272 to rotate in the forward direction under the drive synchronous belt, so that the two lead screws rotate synchronously in the forward direction, and then drive the sliding connecting block 2261 to slide towards the first dynamic limit component 230, thereby driving the movable feeding component 224 to slide towards the fixed feeding component 223; conversely, by rotating the handle-type handwheel 2273 in the reverse direction, the movable feeding component 224 can slide away from the fixed feeding component 223, so that the relative distance between the movable feeding component 224 and the fixed feeding component 223 can be adjusted according to the length or width of different products. After adjustment, reset the hollow diameter of the hollow locking block 2265, causing it to re-lock and limit the lead screw, thereby further improving the stability of the coordinated transmission of the product to be tested by the movable feeding assembly 224 and the fixed unloading assembly 413. (Refer to...) Figure 3 The three sections of the active feeding component 224, the active intermediate component 314, and the active unloading component 414 are adjustable, which further improves the product compatibility of the conveyor belt sealing ring visual inspection equipment in this application.

[0058] Reference Figure 2 and Figure 5The secondary positioning device 500 is disposed between the fixed middle section component 313 and the movable middle section component 314. The secondary positioning device 500 includes a lifting mechanism 510 fixed to the bottom of the frame fixed base plate 100 and passing through the frame fixed base plate 100, and a positioning mechanism 520 disposed at the top of the lifting mechanism 510.

[0059] Reference Figure 5 The lifting mechanism 510 includes a lifting fixing plate 511 fixedly installed at the bottom of the frame fixing base plate 100 and a cylinder lifting assembly 512 installed on the lifting fixing plate 511. The cylinder lifting assembly 512 has a pen-shaped lifting cylinder 5121 that drives the positioning mechanism 520 to switch states and a cylinder top plate 5122 installed at the top of the pen-shaped lifting cylinder 5121 and fixedly installed with the positioning mechanism 520. The pen-shaped lifting cylinder 5121 drives the cylinder top plate 5122 to move up and down reciprocally, thereby driving the product to move up and down reciprocally through the positioning mechanism 520. The lifting mechanism 510 also includes two sets of sliding bushing assemblies 513 symmetrically arranged around the pen-shaped lifting cylinder 5121. Each sliding bushing assembly 513 includes a fixed bushing 5131 fixedly mounted on the lifting fixed plate 511 and a sliding guide rod 5132 passing through the sliding fixed bushing 5131 and positioned at the bottom of the cylinder top plate 5122. Each set of sliding guide rods 5132 has a flexible limiting member 5133 threaded at its shaft end away from the frame fixed base plate 100. The flexible limiting member 5133 limits the movement distance of the positioning mechanism 520 when switching from the first clearance state to the second lifting state. By adjusting the extension length of the flexible limiting member 5133, the switching of the positioning mechanism 520 from the first clearance state to the second lifting state can be controlled according to the product height. The movement distance of the positioning mechanism 520 allows it to accurately lift the product to be inspected to the inspection position of the vision inspection device 600, further improving product compatibility. On the other hand, when the push rod of the pen-shaped lifting cylinder 5121 drives the cylinder top plate 5122 to move up and down, the sliding guide rod 5132, which is slidably set in the fixed bushing 5131, moves up and down synchronously with the cylinder top plate 5122. This allows the sliding guide rod 5132 and the push rod of the pen-shaped lifting cylinder 5121 to work together to support the positioning mechanism 520 through the cylinder top plate 5122. As a result, the positioning mechanism 520 will not deviate or tilt when it drives the product to slide back and forth, thus facilitating the vision inspection device 600 to inspect the product on the positioning mechanism 520.

[0060] Reference Figure 5The positioning mechanism 520 includes a positioning mounting base plate 521 mounted on top of the cylinder top plate 5122, an adjustable limiting block 522 mounted on top of the positioning mounting base plate 521, and a rubber-coated lifting rod 523 fixedly mounted through the positioning mounting base plate 521. The top of the rubber-coated lifting rod 523 is fitted with a rubber sleeve. Multiple rubber-coated lifting rods 523 and adjustable limiting blocks 522 are provided to abut against the product's shape. In the second lifting state, multiple rubber sleeves abut against the inner top wall of the product, and multiple adjustable limiting blocks 522 together match and engage with the outer peripheral wall of the product in the second lifting state. This allows for limiting multiple degrees of freedom of the product according to its external dimensions, further improving the stability of the positioning mechanism 520 when driving the product to slide up and down. Furthermore, the rubber sleeve in the rubber-coated lifting rod 523 facilitates flexible contact with the top of the product, thus protecting the outer surface of the product during lifting.

[0061] Reference Figure 6 The visual inspection device 600 includes a height-adjusting mounting bracket 610, a synchronous belt adjustment mechanism 620 mounted on the height-adjusting mounting bracket 610, and a camera inspection mechanism 630 mounted on the synchronous belt adjustment mechanism 620. The synchronous belt adjustment mechanism 620 includes two sets of opposing slider guide rails 622, two detection synchronous wheels 623 positioned between the slider guide rails 622, a detection synchronous belt 624 wound around the detection synchronous wheels 623, and a detection drive component 621 for driving the detection synchronous wheels 623 to rotate. The camera inspection mechanism 630 is equipped with a detection mounting main board 631 fixed to the sliders of the two sets of slider guide rails 622. The detection mounting main board 631 is equipped with a clamping plate for clamping the detection synchronous belt 624 and a camera light source assembly 632 for detecting whether the product's sealing ring is qualified. Generally, it is necessary to take multiple photos of the sealing ring wound around the charging pile of the sweeping robot to detect whether the sealing ring is misaligned. Controlling the forward and reverse rotation of the detection drive unit 621 enables the detection timing belt 624 to reciprocate along the feed end 311 towards the discharge end 312. This, in turn, via the clamping plate and slider, causes the camera light source assembly 632 to reciprocate along the feed end 311 towards the discharge end 312. This allows the camera light source assembly 632 to perform multi-segment photographic inspections of the assembled sealing rings on the product simultaneously, detecting whether the sealing rings are misaligned. Furthermore, in this embodiment, the detection drive unit 621 is preferably a high-precision servo drive motor, which better ensures the accuracy and stability of the product inspection.

[0062] Reference Figure 6The camera light source assembly 632 includes a camera 6321 mounted on the detection mounting motherboard 631, two sets of strip light sources 6322 fixedly mounted on the detection mounting motherboard 631 and located below the camera 6321, and a backlight source 6324 slidably mounted on the bottom of the detection mounting motherboard 631. The two sets of strip light sources 6322 are symmetrically arranged with their light-emitting areas facing downwards, and the backlight source 6324 is arranged with its light-emitting area facing upwards. It is reciprocated by a slide cylinder 6323 fixedly mounted on the bottom of the detection mounting motherboard 631. The push rod of the slide cylinder 6323 is connected to the backlight source 6324. In the second lifting state, the backlight source 6324 and the two sets of strip light sources 6322 work together to form a supplementary lighting space for illuminating the product. After the positioning mechanism 520 lifts the product to be inspected to the detection position of the camera 6321, the slide cylinder 6323 drives the backlight source 6324 to move away from the detection mounting motherboard 631, thus forming a supplementary lighting space in conjunction with the strip light source 6322. This makes the image captured by the camera 6321 clearer and better reflects the outline and shadow of the sealing ring, facilitating the camera 6321 to perform image detection, thereby improving the accuracy and stability of the image detection by the camera 6321. After the detection is completed, the slide cylinder 6323 drives the backlight source 6324 to reset to avoid the positioning mechanism 520 resetting and moving downward. Furthermore, the camera 6321 in this embodiment is an industrial camera. Compared with ordinary cameras, industrial cameras have a faster shooting frequency and can capture fast-moving objects; industrial cameras have high stability and can stably capture images without packet loss or frame drops during 24-hour continuous operation; at the same time, the raw data output by industrial cameras has a wider spectral range compared to ordinary cameras, resulting in higher image detection efficiency.

[0063] Reference Figures 2 to 6 When the product to be inspected is conveyed above the positioning mechanism 520, the second dynamic limiting component 320 blocks and limits the product to be inspected. At the same time, the intermediate transmission mechanism 310 stops conveying. Then, the pen-shaped lifting cylinder 5121 drives the positioning mechanism 520 to move in the direction closer to the camera 6321, thereby limiting and lifting the product to be inspected into the lighting space between the backlight source 6324 and the strip light source 6322. This is the second lifting state of the secondary positioning device 500; the camera light source component 632 is in the same... Driven by the step belt adjustment mechanism 620, the sealing ring is photographed and inspected in multiple segments. Then, the pen-shaped lifting cylinder 5121 pushes the rod to reset, thereby driving the product to be re-clamped onto the intermediate transmission mechanism 310 through the positioning mechanism 520. After that, the intermediate transmission mechanism 310 starts conveying again, conveying the product to be inspected from the loading transmission mechanism 220 to the second dynamic limit component 320, while simultaneously conveying the inspected product to the unloading transmission mechanism 410. At this time, it is the first avoidance state of the secondary positioning device 500.
