Description

Technical Field

[0001] The present invention relates to the field of cultural and creative product production, and in particular to a sorting and conveying device for the production and preparation of cultural and creative products based on industrial vision. Background Art

[0002] In the large-scale production of ceramic cultural and creative products, simultaneous appearance inspection during the transportation or storage process can eliminate independent workstations and greatly improve efficiency. However, the highly reflective nature of ceramic glaze, irregular shapes, and large weight spans require that inspection overcome the dynamic challenges of motion interference, light fluctuations, and clamping adaptation.

[0003] Existing conveying equipment often adopts an intermittent conveying method to realize visual inspection of cultural and creative products during the conveying process. However, when using the above-mentioned existing conveying equipment to convey cultural and creative products, when the cultural and creative products are conveyed to the position below the industrial camera, the posture of the cultural and creative products cannot be dynamically adjusted, resulting in the industrial camera only being able to collect single-perspective images when collecting the image information of the cultural and creative products, which is prone to blind spots in collection, resulting in an increase in the misjudgment rate in the sorting link and an increase in the loss of good products, which restricts the inspection efficiency of large-scale production. Summary of the Invention

[0011] Furthermore, arc-shaped intermittent teeth and three pins are provided on the side of the intermittent transmission turntable close to the slide, and an intermittent rack is provided on the side of the slide close to the power belt. The intermittent rack is engaged with the intermittent transmission turntable, and the intermittent rack includes advancing teeth and stopping teeth. The advancing teeth are engaged with the arc-shaped intermittent teeth, and the stopping teeth are engaged with the pins.

[0012] Furthermore, the clamping mechanism includes a rotating gear, which passes through the side wall of the slide and is provided with a rotating bevel gear. A rotating transmission shaft is provided on the lower side of the bevel gear. A rotating belt is provided at the lower end of the rotating transmission shaft. A rotating base is provided at the end of the rotating belt away from the rotating transmission shaft.

[0013] Furthermore, a return spring is provided at the center of the rotating base, a tray is provided at the top of the return spring, and a plurality of clamping claws are slidably connected to the side of the tray in a circular array.

[0014] Furthermore, the lower side of the clamping jaw is rotatably connected to the rotating base, and the top end of the clamping jaw is covered with a rubber sleeve.

[0015] Furthermore, a pulley is provided on the side of the slide away from the intermittent transmission turntable, and the pulley is provided on the top of the fixed bracket.

[0016] Furthermore, a polarizing disk is rotatably connected to the upper surface of the light-shielding channel on one side of the industrial inspection camera, and an outer side wall of the polarizing disk is engaged with the polarization transmission axis.

[0017] Furthermore, a side rack is provided on the side of the slide where the second transmission shaft is located, and the side rack is engaged with the top end of the second transmission shaft.

[0018] Furthermore, the polarization disk is provided with a polarizing plate in a circular shape, and the polarizing plate is located directly below the industrial detection camera.

[0019] Furthermore, an inclined mirror is fixedly mounted on the upper surface of the shading channel, and the inclined mirror is located parallel to the intermittent transmission turntable.

[0020] Furthermore, a light source is fixedly mounted on the inner wall of the light-shielding channel directly above the inclined mirror surface, and the horizontal height of the inclined mirror surface is equal to that of the rotating base.

[0021] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] 1. The present invention is provided with a rotating detection structure in which an intermittent transmission turntable is linked to a clamping mechanism. During the conveying process of cultural and creative products, the rotating half-tooth segment is engaged with the rotating gear of the clamping mechanism, so that the clamped cultural and creative products are accurately rotated one circle when they are conveyed to the bottom of the industrial inspection camera. In conjunction with the fixed inspection station in the light-shielding channel, 360° non-dead-angle detection of the surface of ceramic products is achieved, avoiding the detection blind spots of traditional linear conveying. It is particularly suitable for full-surface detection of special-shaped cultural and creative products. It adapts to the intermittent flow rhythm of the conveyor line and can complete full-surface detection during the conveying pauses, solving the detection blind spot problem caused by movement in traditional continuous conveying, providing full-dimensional defect data for subsequent sorting links, reducing misjudgment caused by omission of viewing angles, improving sorting accuracy and efficiency, and ensuring the reliability of quality screening of cultural and creative products.

[0023] 2. The present invention is provided with circular polarizers with a gradient angle distribution, which cover a continuous polarization direction of 0-360° along the circumferential direction. When the conveyor line is transporting cultural and creative products, the polarization disk rotates continuously, and each area of its surface is dynamically modulated by polarizers at different angles in turn, effectively suppressing mirror reflection light and enhancing defect scattered light, thereby increasing the defect signal intensity and reducing overexposed areas, significantly improving the algorithm's ability to identify subtle defects, and coping with the dynamic interference of reflected light with different curvatures on the surface of special-shaped ceramics. It maintains stable light control under light fluctuations during conveying flow, solving the problem that fixed light sources cannot adapt to the dynamic reflection of ceramic glaze.

[0024] 3. The present invention is equipped with a composite optical path system consisting of an oblique mirror and a corresponding light source, which matches the continuous flow efficiency of the conveyor line and completes multi-view acquisition in a single stop at the conveying station, reducing the hardware cost and detection blind spots of the traditional multi-camera solution. By utilizing the reflective optical path design of the oblique mirror, the industrial inspection camera can simultaneously capture the side image reflected by the mirror while collecting the image of the ceramic top surface. Dual-view detection can be completed in one rotation, thereby improving detection efficiency, reducing the complexity of the mechanical structure, and reducing hardware costs.

[0025] 4. The present invention is provided with an adaptive clamping mechanism composed of a return spring and a silicone clamping claw. During the conveying process, the slide moves continuously with the conveyor line. When the clamping claw holding the cultural and creative products moves to the bottom of the industrial inspection camera, the rotating bevel gear is driven by the rotating half-tooth segment. The rotating transmission shaft engaged with the rotating bevel gear drives the clamping claw to rotate one circle under the industrial inspection camera through the rotating belt, thereby realizing multi-angle one-time detection during the conveying process.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] The present invention will be further described below with reference to the embodiments.

[0045] Example

[0046] Reference Figure 1-10 The sorting and conveying device for the production and preparation of cultural and creative products based on industrial vision provided by the present invention includes a shading channel 1. The shading channel 1 is made of black shading plates, and the inner wall is sprayed with a matte coating to isolate external ambient light. A fixed bracket 2 is fixedly installed on its lower surface. The fixed bracket 2 is a rectangular frame structure. A vertical slide rail is provided on the inner side of the upper end. The slide 3 can slide in the vertical direction through a linear bearing and the slide rail. A motor 4 is fixedly installed on the outer side below the fixed bracket 2. The output shaft of the motor 4 passes through the side wall of the bracket and is connected to the driving wheel 412.

[0047] A power belt 413 is sleeved on the outside of the driving wheel 412, and the power belt 413 is engaged with the driven wheel 4141 of the intermittent transmission mechanism for transmission. The intermittent transmission mechanism includes an intermittent transmission turntable 414, and the driven wheel 4141 is coaxially fixed on the side away from the slide 3. A rotating half-tooth segment 4143 is provided on the arc side wall near the slide 3. The rotating half-tooth segment 4143 is engaged with the rotating gear 511 of the clamping mechanism 5, so that the clamped cultural and creative products can be accurately rotated one circle when they are transported to the bottom of the industrial inspection camera 63, realizing 360° dead-angle detection of the surface of ceramic products. The driven wheel 4141 and the intermittent transmission turntable 414 are connected to the polarization transmission shaft 61 through a synchronous belt 6. The upper end of the polarization transmission shaft 61 is engaged with the polarization disk 62. The industrial inspection camera 63 is fixed on the upper surface of the inner part of the shading channel 1, and its optical axis is vertically downward facing the detection area.

[0048] The industrial inspection camera 63 captures the image of the object through precise optical imaging and transmits the image to the computer at high speed. The computer uses image processing and AI algorithms to analyze the image content, and finally automatically outputs a decision signal based on the analysis results, driving the production line to perform sorting, alarm or adjustment actions, thereby realizing unmanned, high-precision industrial quality inspection and process control.

[0049] The intermittent transmission turntable 414 is designed with a unique arc-shaped intermittent tooth 4142 and three evenly distributed pins 4144 on the side close to the slide 3. The corresponding side of the slide 3 is fixedly connected to the intermittent rack 31. The intermittent rack 31 is divided into two sections with different tooth structures. One section is a traveling tooth 311 with a straight tooth structure, and the lower section is a pause tooth 312 with a helical tooth structure. When the slide 3 is in the upper position during transportation, the traveling tooth 311 is fully engaged with the arc-shaped intermittent tooth 4142, and the turntable is locked in a stationary state by the rigid bite of the straight teeth. At this time, the ceramic product stays stably at the inspection station, which is convenient for the industrial inspection camera 63 to perform high-resolution static image acquisition, ensuring clear imaging of subtle defects, providing full-dimensional defect data for subsequent sorting links, reducing misjudgments caused by omissions of viewing angles, improving sorting accuracy and efficiency, and ensuring the reliability of quality screening of cultural and creative products.

[0050] When the slide 3 moves downward to the lower position, the stop tooth 312 contacts and engages with the pin 4144. The stop tooth 312 with the helical tooth structure pushes the pin 4144 through the axial component force, driving the turntable to rotate at a constant speed, so that the ceramic product enters the dynamic detection mode and completes a 360° surface scan during the rotation process.

[0051] This "pause-rotation" intermittent motion mode achieves seamless switching through the up and down movement of the slide 3, which not only ensures the stability of static detection, but also meets the comprehensiveness of dynamic detection, avoiding the image blur problem that may occur in traditional continuous rotation detection. At the same time, through the precise coordination of the mechanical structure, it ensures that the ceramic products are always in the ideal detection position during the detection process, thereby improving the controllability of the detection process and the reliability of the detection results.

[0052] The core of the clamping mechanism 5 is to realize power transmission and rotation control through multi-stage gear transmission, ensuring that the ceramic products rotate stably and the center positioning is accurate during the inspection process. The rotating gear 511 is installed on the side wall of the slide 3, and its shaft end is connected to the rotating bevel gear 51. The horizontal rotation movement of the intermittent transmission turntable 414 is converted into the vertical rotation movement of the rotating transmission shaft 52 through the bevel gear transmission. This transmission method can change the direction of power transmission and realize speed adjustment through the gear ratio. The lower end of the rotating transmission shaft 52 is connected to the rotating base 53 through a rotating belt 535 to form a flexible transmission, which can not only transmit power but also buffer the impact during the transmission process.

[0053] The rotating base 53 serves as a supporting platform for ceramic products. Its rotation axis is strictly aligned with the axis of the intermittent transmission turntable 414 to ensure that the center position of the product remains unchanged during rotation, avoiding detection blind spots or image distortion caused by eccentric rotation.

[0054] By matching the speed of the gear transmission chain, the product can be rotated at an appropriate speed. Combined with the frame rate of the industrial inspection camera 63, one frame of image can be captured for every certain rotation angle, ensuring comprehensive inspection coverage and clear images. This structural design not only ensures the stability of the mechanical transmission, but also improves the accuracy and reliability of inspection through precise axis positioning and speed control. It is suitable for the automated inspection needs of ceramic cultural and creative products of different sizes and shapes.

[0055] A return spring 534 is provided in the center of the rotating base 53, and its top end is connected to the tray 531. The side of the tray 531 is slidably connected to multiple clamping claws 532 to form an adaptive clamping structure. When the ceramic product is placed on the tray 531, the weight of the product will press down the tray 531, causing the return spring 534 to compress. The return spring 534 generates an upward elastic force through elastic deformation, pushing the tray 531 to drive the clamping claws 532 to move radially, thereby clamping the product.

[0056] The return spring 534 allows the clamping force to be automatically adjusted according to the size of the product - if the product size is large, the return spring 534 is compressed more and the clamping force is greater; if the product size is small, the return spring 534 is compressed less and the clamping force is smaller. This can not only stably fix the product, but also will not damage the fragile ceramic surface due to excessive clamping force, such as thin-bodied porcelain or underglaze colored products.

[0057] The sliding design of the clamping jaw 532 enables it to open and close flexibly according to the shape and size of the product, and can adapt to ceramic cultural and creative products of different sizes without manual adjustment. Whether it is a smaller teacup or a larger vase, it can be stably clamped through the elastic action of the reset spring 534. The top of the clamping jaw 532 is made of soft material, which can buffer the pressure when contacting the product and avoid scratches or damage to the glaze caused by hard contact. This flexible clamping method not only ensures the stability of the product during the inspection process, but also effectively protects the integrity of high-value-added cultural and creative products. It is suitable for diverse cultural and creative product inspection needs and improves the versatility and reliability of the equipment.

[0058] The lower side of the clamping jaw 532 is rotatably connected to the rotating base 53 via a pin shaft, and the top is covered with a buffer material to reduce the direct impact on the ceramic surface during clamping. The elastic properties of the buffer material can adapt to the surface curvature of the ceramic product, enhancing the clamping stability while effectively protecting the glaze integrity of high-value-added cultural and creative products.

[0059] A pulley 32 is provided on the side of the slide 3 away from the intermittent transmission turntable 414. The pulley 32 cooperates with the slide rail at the top of the fixed bracket 2 to form a rolling guide structure, which significantly reduces the friction resistance of the slide 3 during vertical sliding, improves the smoothness of movement, ensures the meshing accuracy of the intermittent rack 31 and the turntable, and thus ensures the reliability of the intermittent transmission and the positioning accuracy of the detection station.

[0060] The upper surface of the light-shielding channel 1 on one side of the industrial inspection camera 63 is rotatably connected to the polarization disk 62, and the outer wall of the polarization disk 62 is engaged with the polarization transmission shaft 61. The transmission of the synchronous belt 6 ensures that the rotation angle of the polarization disk 62 is synchronized with that of the intermittent transmission turntable 414. When the ceramic product rotates, the polarization direction of the polarizer 621 covers different areas of its surface in turn, thereby realizing dynamic polarization modulation of the highly reflective glaze.

[0061] The polarization disk 62 is provided with a circular polarizer 621, which is located directly below the industrial inspection camera 63. The polarizer 621 is provided with a gradient polarization direction along the circumference. When the conveyor line is conveying cultural and creative products, the polarization disk rotates continuously, and each area of its surface is dynamically modulated by polarizers at different angles in turn, effectively suppressing the mirror reflected light and enhancing the scattered light of the defect, thereby increasing the defect signal intensity and reducing the over-exposed area, significantly improving the algorithm's ability to identify subtle defects, and responding to the dynamic interference of the reflected light with different curvatures on the surface of special-shaped ceramics by filtering the mirror reflected light at different angles. When the ceramic product rotates with the turntable, each area of the surface is modulated with different polarization angles in turn, enhancing the contrast between the defect characteristics and the background, making it easier for the industrial inspection camera 63 to capture subtle defects such as cracks and bubbles.

[0062] An inclined mirror 21 is fixedly installed on the upper surface of the shading channel 1. The inclined mirror 21 is parallel to the intermittent transmission turntable 414 and inclined at 45°. Its position is designed so that the light from the light source 64 is reflected by the mirror and illuminates the side of the ceramic product at a suitable angle. At the same time, the industrial inspection camera 63 can synchronously collect the side image through the reflection of the inclined mirror 21, forming a composite inspection light path of the top and side surfaces, reducing the detection blind area and improving the detection efficiency.

[0063] A light source 64 is fixedly installed on the inner wall of the shading channel 1 directly above the oblique mirror 21. The light emitted by the light source 64 is reflected by the oblique mirror 21 and evenly illuminates the side of the ceramic product. Combined with the filtering effect of the polarizer 621, the glare of the highly reflective surface is suppressed. The reflective light path design of the oblique mirror allows the industrial inspection camera to capture the side image reflected by the mirror while collecting the image of the top surface of the ceramic to enhance the uniformity of lighting in the inspection area. The industrial inspection camera 63 simultaneously collects the top and side images, and through multi-perspective image fusion analysis, it can realize the accurate identification of 360° surface defects of ceramic products.

[0064] Working principle:

[0065] The shading channel 1 serves as the core detection space and adopts a double-layer structure design. The inner layer is a black shading material board, and the outer layer is a steel structure board. The two layers are filled with matte material to form a composite shading wall. After testing, it can block almost all external ambient light, and the internal environmental illumination is strictly controlled. The lower surface of the shading channel 1 is connected to the fixed bracket 2 by bolts. The fixed bracket 2 is a steel structure frame with adjustable anchor bolts at the bottom. After calibration, it can adapt to the flatness deviation of the workshop floor to ensure that the overall levelness error of the equipment is within a reasonable range.

[0066] A high-precision linear guide is installed vertically on the inner side of the fixed bracket 2, and the slide 3 cooperates with it through a linear slider. The slider has a built-in ball cage that can withstand a certain radial load. The friction coefficient is extremely low during sliding, ensuring that the slide 3 is lifted and lowered smoothly. A nylon pulley 32 is installed on the vertical plate on the side of the slide 3 away from the intermittent transmission turntable 414 through a bearing seat. The pulley 32 forms rolling contact with the slide rail at the top of the fixed bracket 2, further reducing friction, making the thrust required for the slide 3 to be lifted and lowered smaller, and at the same time limiting the lateral displacement deviation, ensuring that the intermittent rack 31 and the intermittent transmission turntable 414 always maintain parallel meshing.

[0067] The servo motor 4 is fixed to the outer side below the fixed bracket 2 through a shock-proof base. The output shaft of the motor 4 is connected to the driving wheel 412 through an elastic coupling, which can compensate for the offset between the axes and avoid the generation of additional torque during the transmission process. The driving wheel 412 is a trapezoidal pulley with a special surface treatment, forming a multi-groove meshing with the polyurethane synchronous belt power belt 413, and has a high transmission efficiency.

[0068] The synchronous belt 6 and the power belt 413 are equipped with automatic tensioning devices to provide constant tensioning force, and integrated sensors for real-time monitoring. When the belt is loose, the system automatically alarms and prompts maintenance. The power is decelerated by the synchronous power belt 413 and then transmitted to the driven pulley 4141 of the intermittent transmission mechanism. The driven pulley 4141 is connected to the intermittent transmission turntable 414 by a key to ensure reliable power transmission.

[0069] The intermittent transmission turntable 414 is made of alloy structural steel forgings. After tempering, the arc intermittent teeth 4142 and pins 4144 are processed by CNC technology. The curvature radius and central angle of the arc intermittent teeth 4142 are reasonably designed. When meshing with the traveling teeth 311, the contact length is long, which can withstand large braking torque and ensure high positioning accuracy when the turntable is stationary.

[0070] The three pins 4144 are evenly distributed around the circumference and protrude a certain length from the surface of the turntable. The material is quenched and, when engaged with the pause tooth 312, the turntable is driven to rotate at a constant speed through the axial component of the helical teeth. Combined with the encoder feedback of the servo motor 4, the rotation angle error is effectively controlled. The intermittent rack 31 on the slide 3 is made of carburized steel with a high surface hardness. The tooth surface is ground, and the meshing clearance with the turntable is controlled within a reasonable range to reduce impact and noise.

[0071] The rotating gear 511 of the clamping mechanism 5 is mounted on the side wall of the slide 3 through a deep groove ball bearing. The shaft end is connected to the rotating bevel gear 51 through a coupling, converting the rotational motion of the turntable into the vertical motion of the rotating transmission shaft 52.

[0072] The rotating transmission shaft 52 adopts a hollow shaft design to reduce weight while ensuring torsional strength. The lower end is connected to the micro synchronous belt rotating belt 535 through a synchronous pulley to drive the rotating base 53 to rotate.

[0073] The rotating base 53 is an aluminum alloy disc with an annular groove on its upper surface. An anti-skid pad is pasted in the groove to effectively prevent the ceramic product from sliding during rotation.

[0074] A cylindrical compression return spring 534 is vertically installed in the center of the rotating base 53. The initial compression can provide a certain clamping force. The clamping force at the maximum compression can meet different needs. The tray 531 is made of engineering plastic. The center of the bottom surface is connected to the top of the return spring 534. Dovetail slide rails are evenly distributed along the circumference of the side. A miniature ball slider is installed in each slide rail. The slider is connected to the clamping claw 532 by screws, so that the clamping claw 532 can slide radially along the slide rail with small sliding resistance.

[0075] The three clamping jaws 532 are distributed in an array, and the lower ends are rotatably connected to the rotating base 53 through stainless steel pins. Retaining springs are installed at both ends of the pins to prevent them from falling off. The rotational clearance is extremely small. A food-grade silicone rubber sleeve is pasted on the inner side of the top of the clamping jaw 532, and the surface is molded with anti-slip patterns, which can evenly distribute the clamping force on the ceramic surface to avoid damage to fragile products.

[0076] In the optical detection system, the polarization disk 62 is installed on the top of the shading channel 1 through a thrust ball bearing, and the outer wall is processed with involute straight teeth to form a reduction transmission with the small gear at the top of the polarization transmission shaft 61, so that the rotation speed of the polarization disk 62 matches the rotation speed of the intermittent transmission turntable 414, ensuring that when the ceramic product rotates, the polarization direction of the polarizer 621 covers different ranges in turn, and each detection position corresponds to a specific polarization angle change.

[0077] The polarizer 621 is manufactured using a multi-layer composite film process. Films with different polarization directions are pasted in sequence at certain intervals along the circumference. Adjacent films are connected by a gradient transition layer. It has a high extinction ratio and high light transmission axis accuracy. The effective light transmission area is completely matched with the field of view of the industrial inspection camera 63.

[0078] The inclined mirror surface 21 is made of optical glass with a coating and is fixed to the upper surface of the light-shielding channel 1 via a bracket with angle adjustment screws. The mirror surface is tilted at a suitable angle to the horizontal plane. The horizontal distance between the center of the mirror surface and the center of the intermittent transmission turntable 414, as well as the height of the bottom edge of the mirror surface, are rationally designed. An LED line light source 64 is mounted directly above the inclined mirror surface 21, equipped with a diffuser to ensure uniform illumination. The light intensity can be continuously adjusted via a controller.

[0079] The light source 64 shines vertically downward onto the inclined mirror surface 21, and after reflection, it illuminates the side of the ceramic product at a suitable incident angle. This angle can cause moderate diffuse reflection of the light on the glaze surface, avoiding strong reflections caused by vertical incidence. At the same time, it ensures that when the industrial inspection camera 63 collects the side image through mirror reflection, the incident angle and the reflection angle conform to the principles of geometric optics, and the image distortion is small.

[0080] During the equipment operation, when the ceramic product is placed on the tray 531 of the rotating base 53, the return spring 534 pushes the tray 531 upward, and the clamping claws 532 radially tighten to clamp the product. At this time, the slide 3 drives the relevant transmission components through the motor 4 according to the height of the product, drives the side rack to move vertically, and adjusts the meshing position of the intermittent rack 31 and the turntable.

[0081] After the motor 4 is started, the power is transmitted to the driven pulley 4141 through the power belt 413, driving the intermittent transmission turntable 414 to rotate. At the same time, the synchronous belt 6 drives the polarization transmission shaft 61 to rotate, so that the polarization disk 62 rotates synchronously with the turntable. The circular polarizer 621 on the polarization disk 62 rotates accordingly, and its circumferentially gradient polarization direction sequentially covers the surface of the ceramic product, dynamically modulating the reflected light to suppress reflections.

[0082] The industrial inspection camera 63 continuously captures images at a set frame rate. Every time the turntable drives the product to rotate a certain angle, the system triggers a shot to ensure that each area on the surface of the product can correspond to light conditions with different polarization angles, forming multi-angle image data.

[0083] For unqualified products detected, the subsequent system controls the operation of the sorting cylinder through PLC to remove them, while qualified products continue to be transported along the conveyor belt to achieve automated sorting.

[0084] This device significantly improves the inspection efficiency and accuracy of ceramic cultural and creative products through high-precision control of mechanical transmission, dynamic polarization modulation of optical detection, and multi-view imaging technology.
