Description

Technical Field

[0001] This utility model relates to the field of badminton shuttlecock detection, and more specifically, to a badminton shuttlecock detection device. Background Technology

[0002] Badminton shuttlecock inspection needs to cover appearance defects (broken shafts, color differences, missing shafts, etc.) and dynamic performance (rotation speed, swing state). Traditional inspection relies on manual operation. Due to the natural differences in shape and weight of feathers, manual inspection is inefficient and prone to missed or false detections due to visual fatigue. At the same time, the training cycle for manual inspection is long and costly, making it difficult to adapt to the needs of large-scale production.

[0003] To achieve automation upgrades, such as the badminton shuttlecock inspection machine disclosed in patent number CN111054645A, which uses a shuttlecock loading mechanism, a rotating disc inspection station, and dual cameras to inspect shuttlecocks, the following problems still exist: First, the appearance inspection relies solely on fixed-angle shooting by dual cameras, lacking a multi-station division of labor design. Hidden defects such as splicing holes at the base of the shuttlecock shaft and minor damage to the feather tips are easily missed, and it cannot comprehensively identify more than ten types of defects such as uneven feather spacing and cut roots. Second, it lacks a dynamic detection module, and can only judge the appearance compliance. It cannot simulate the actual flight environment to detect the shuttlecock's rotation speed and swing amplitude, resulting in products that pass the appearance test but have poor dynamic performance entering the market. Utility Model Content

[0004] The purpose of this invention is to provide a badminton shuttlecock detection device to solve the technical problems existing in the background art.

[0005] This utility model provides a badminton detection device, including a detection host, a feeding component and a rotary conveying component disposed on the detection host, as well as an appearance detection station and a dynamic detection station for detecting the rotation speed and swing state of the badminton shuttlecock located on the outer periphery of the rotary conveying component. The appearance detection station and the dynamic detection station are arranged sequentially along the conveying path of the rotary conveying component.

[0006] The rotary conveying assembly includes a rotary table and a conveying seat that is mounted on the rotary table and can rotate on its own. When the conveying seat reaches the appearance inspection station, it rotates one revolution.

[0007] The bottom of the dynamic detection station is equipped with a wind tunnel structure and a blowing module. The blowing module blows air into the wind tunnel structure from bottom to top, and the badminton shuttlecock is suspended and rotating when it is located inside the wind tunnel structure.

[0008] In a preferred embodiment, the feeding assembly includes an inclined feeding chute, a feeding cylinder corresponding to the discharge end of the feeding chute, a clamping and feeding component located at the discharge port of the feeding cylinder, and a transfer component that works in conjunction with the clamping and feeding component. The clamping and feeding component clamps the shuttlecocks on the feeding cylinder and feeds them to the transfer component, which then feeds the shuttlecocks to the conveying seat.

[0009] In a preferred embodiment, the feed cylinder includes a cylindrical body and a conical body located below the cylindrical body, and after the badminton shuttlecock falls into the feed cylinder, its head passes through the conical body.

[0010] In a preferred embodiment, the transfer member includes a transfer frame extending above the rotary table and having a transfer ring, and a transfer cylinder located above the transfer frame and concentrically arranged with the transfer ring, the transfer cylinder pushing a shuttlecock located on the transfer ring onto the feed seat.

[0011] In a preferred embodiment, the feeding seat includes an electric rotating seat and a limiting ring sleeved on the outside of the electric rotating seat, and the top end of the electric rotating seat is configured as an arc-shaped structure adapted to the shape of a badminton shuttlecock head.

[0012] In a preferred embodiment, the appearance inspection station includes inspection station one, inspection station two, and inspection station three arranged sequentially along the badminton shuttlecock conveying path;

[0013] The first detection station includes a camera and a light source located below the camera. The light source is a ring light source and is set concentrically with the camera. The camera takes pictures vertically downward.

[0014] The second detection station includes camera two, camera three, light source two, light source three, and light source four. Light source two is a ring light source, light source three is a surface light source, and light source four is a strip light source. Light source two is located directly above the badminton shuttlecock, and light source three and light source four are located on the side of the badminton shuttlecock. Camera two is used in conjunction with light source two and light source three, and camera three is used in conjunction with light source four. Camera three and camera four are distributed on both sides of the badminton shuttlecock and are both tilted downwards to take pictures.

[0015] The detection station three includes camera four, light source five, light source six and light source seven. Light source five, light source six and light source seven are all strip light sources. Camera four is tilted upward to take pictures.

[0016] In a preferred embodiment, the dynamic detection station includes a camera five and a light source eight located below the camera five. The light source eight is a ring light source. The camera five, the light source eight, and the air duct structure are concentrically arranged. The camera one takes pictures vertically downward.

[0017] In a preferred embodiment, a clamping and feeding component two for transferring badminton shuttlecocks from the feeding seat to the air duct structure is provided between the dynamic detection station and the rotary table, and a baffle structure is provided above the clamping part of the clamping and feeding component two.

[0020] Through the collaborative work of the three visual inspection stations, coupled with multiple cameras and multiple light sources, more than ten kinds of visual defects such as uneven gaps between the nails, broken rods, and missing rods can be accurately identified. Dynamic inspection uses the 128-type wind tunnel structure to simulate the actual flight environment. Combined with the dynamic inspection station, this prevents products that pass the appearance test but have abnormal flight performance from entering the market. Attached Figure Description

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0040] like Figure 1As shown, the badminton detection device disclosed in this utility model is part of a badminton detection and sorting conveying equipment. The badminton detection and sorting conveying equipment includes a detection device 100, a sorting conveying device 300 and a feeding auxiliary device 200 located at the discharge end of the detection device 100 and assisting the badminton shuttles to enter the sorting conveying device 300, arranged in sequence.

[0041] In the above scheme, the badminton shuttlecock to be tested first enters the testing device 100 to complete the appearance and dynamic performance testing. After the testing is completed, the shuttlecock is adjusted by the unloading auxiliary device 200 to avoid tilting. Finally, it enters the classification and conveying device 300 to complete the classification and orderly conveying according to the testing level. The modular design ensures that the overall process is connected in an orderly manner, improves the continuous operation efficiency of the equipment, and reduces the risk of material accumulation.

[0042] like Figure 2 As shown, the detection device 100 includes a detection host 101, a feeding assembly and a rotary conveying assembly disposed on the detection host 101, as well as an appearance detection station located on the outer periphery of the rotary conveying assembly and a dynamic detection station for detecting the rotation speed and swing state of the badminton shuttlecock. The appearance detection station and the dynamic detection station are arranged sequentially along the conveying path of the rotary conveying assembly.

[0043] At the testing device 100, the feeding component transports the shuttlecock to the feeding seat 110 of the rotary feeding component. The rotary feeding component drives the shuttlecock to move along a circumferential path. It first passes through the appearance inspection station to complete the appearance defect detection such as the shuttlecock shaft and the shuttlecock tip, and then enters the dynamic inspection station to complete the speed and swing state detection. The detection data is transmitted to the testing host 101 for processing in real time.

[0044] like Figure 3 As shown, the feeding assembly includes an inclined feeding chute 102, a feeding cylinder corresponding to the discharge end of the feeding chute 102, a clamping and feeding component 105 located at the discharge port of the feeding cylinder, and a transfer component that works in conjunction with the clamping and feeding component 105. The clamping and feeding component 105 clamps the shuttlecocks on the feeding cylinder and feeds them to the transfer component, which then feeds the shuttlecocks to the conveying seat 110.

[0045] The shuttlecock to be tested slides into the feeding cylinder along the inclined feeding chute 102 under gravity. The feeding cylinder performs initial posture correction on the shuttlecock. Then, the clamping and feeding component 105 (such as a cylinder gripper) clamps the head of the shuttlecock from the outlet of the feeding cylinder and smoothly transfers it to the transfer component. Finally, the transfer component accurately places the shuttlecock onto the feeding seat 110 of the rotating conveying assembly. The clamping and feeding component 1 is a conventional moving part, which adopts a combined drive structure of lifting, rotating, and clamping.

[0046] The feeding cylinder includes a cylindrical body 103 and a conical body 104 located below the cylindrical body 103. After the shuttlecock falls into the feeding cylinder, its head passes through the conical body 104. After falling into the cylindrical body 103 from above, the shuttlecock moves towards the conical body 104 under the action of gravity. The tapered structure of the conical body 104 guides the shuttlecock head downward and the feathers upward, and finally the head passes through the opening of the conical body 104, achieving the initial uniformity of the shuttlecock's posture.

[0047] The transfer component includes a transfer frame 106 extending above the rotary table 109 and equipped with a transfer ring 107, and a transfer cylinder 108 located above the transfer frame 106 and concentrically arranged with the transfer ring 107. A clamping and feeding component 105 places the shuttlecocks inside the transfer ring 107. When the feeding seat 110 of the rotating conveying assembly moves directly below the transfer ring 107, the transfer cylinder 108 drives the piston rod to push downwards, smoothly pressing the shuttlecocks inside the transfer ring 107 onto the feeding seat 110.

[0048] The rotary conveying assembly includes a rotary table 109 and a self-rotating conveying seat 110 disposed on the rotary table 109. When the conveying seat 110 reaches the appearance inspection station, it rotates one revolution. The transfer cylinder 108 pushes the shuttlecock located on the transfer ring 107 onto the conveying seat 110.

[0049] In the above scheme, the rotary table 109 rotates at a constant speed under the drive mechanism (such as a stepper motor), driving the circumferentially distributed conveyor seats 110 to pass sequentially through the loading position, appearance inspection position, and dynamic inspection position. When the conveyor seat 110 reaches the appearance inspection position, the drive component (such as a micro motor) on the conveyor seat 110 drives it to rotate one revolution, cooperating with the camera at the appearance inspection position to complete full-angle shooting. At the same time, the transfer cylinder 108 accurately pushes the shuttlecock onto the unloaded conveyor seat 110. The conveyor seat 110 adopts a self-rotating design to achieve 360° appearance inspection of the shuttlecock without blind spots, solving the problem of missed inspection of the base of the shuttlecock and the tip of the shuttlecock caused by fixed-angle shooting in existing equipment.

[0050] The feeding seat 110 includes an electric rotating seat 112 and a limiting ring 111 sleeved on the outside of the electric rotating seat 112. The top end of the electric rotating seat 112 is configured with an arc-shaped structure adapted to the shape of a badminton shuttlecock head. When the badminton shuttlecock is pushed onto the feeding seat 110, the shuttlecock head fits against the arc-shaped structure at the top end of the electric rotating seat 112, and the limiting ring 111 surrounds the outside of the shuttlecock feathers to prevent the shuttlecock from shifting or falling during the rotation of the electric rotating seat 112 or the movement of the rotating table 109. The electric rotating seat 112 drives the badminton shuttlecock to rotate synchronously, cooperating with the camera and light source at the detection station to complete image acquisition. The arc-shaped structure adapts to the shuttlecock head, improving the stability of the badminton shuttlecock placement, and the limiting ring 111 prevents the feathers from flipping outward due to centrifugal force during rotation, thus protecting the feathers and ensuring clear images captured by the camera, improving detection accuracy.

[0051] like Figure 4 As shown, the appearance inspection station includes inspection station one, inspection station two, and inspection station three arranged sequentially along the shuttlecock conveying path. All cameras used in this inspection solution are area scan cameras. The rotating conveyor assembly drives the shuttlecock through the three inspection stations sequentially. Inspection station one collects macroscopic data such as the shuttlecock's diameter and roundness from the top; inspection station two collects internal and root defects of the shuttlecock shaft from an obliquely upward angle; and inspection station three collects external defects of the shuttlecock shaft from a side and below. The inspection data from the three stations are summarized and sent to the inspection host 101 for a comprehensive judgment on whether the shuttlecock's appearance is qualified. Through multi-station division of labor inspection, more than ten types of defects are covered, including feather spacing, color difference, broken shafts, and missing shafts, avoiding blind spots in single-station inspections.

[0052] like Figure 5 As shown, the first inspection station includes a camera 113 and a light source 114 located below the camera 113. The light source 114 is a ring light source concentrically set with the camera 113, and the camera 113 takes images vertically downwards. When the badminton shuttlecock arrives at the first inspection station along with the feeder 110, the light source 114 evenly illuminates the top of the shuttlecock, forming a shadow-free lighting environment. The camera 113 takes an image of the top of the shuttlecock vertically downwards. The image is processed by an external image processor, and it is determined whether macroscopic parameters such as the spacing between the shuttlecock shafts, the diameter, and the roundness meet the standards, thus initially identifying the current quality status of the shuttlecock.

[0053] like Figure 6As shown, the second detection station includes camera 2 115, camera 3 116, light source 2 117, light source 3 118, and light source 4 119. Light source 2 117 is a ring light source, light source 3 118 is a surface light source, and light source 4 119 is a strip light source. Light source 2 117 is located directly above the badminton shuttlecock, and light source 3 118 and light source 4 119 are located on the side of the badminton shuttlecock. Camera 2 115 is used in conjunction with light source 2 117 and light source 3 118, and camera 3 116 is used in conjunction with light source 4 119. Camera 3 116 and camera 4 120 are distributed on both sides of the badminton shuttlecock and are both tilted downwards to take pictures.

[0054] When the shuttlecock arrives at inspection station two, light source two 117 provides auxiliary illumination from above, while light source three 118 illuminates the inside of the shuttlecock's shaft from one side. Camera two 115 takes a tilted overhead shot to identify defects such as uneven feather color, black spots, dirt, and reversed feathers. Simultaneously, light source four 119 focuses on the base of the shaft from another side, and camera three 116 takes a tilted overhead shot to identify hidden defects such as spliced ​​holes, cut roots, and missing shafts. Both cameras use multi-frame shooting to ensure no defects are missed. The angles between cameras two 115 and three 116 and the horizontal plane are both approximately 50°.

[0055] like Figure 7 As shown, the inspection station three includes a camera 120, a light source 121, a light source 122, and a light source 123. Light sources 121, 122, and 123 are all strip light sources. The camera 120 is tilted upwards to capture images. When the shuttlecock reaches the inspection station three, light sources 121, 122, and 123 illuminate the shuttlecock's outer shaft from different side angles, creating a contrast between light and dark to highlight the surface undulations of the shaft. The camera 120 tilts upwards from the lower side to capture defects such as folds and wrinkles on the outer shaft. The angle between the camera 120 and the horizontal plane is approximately 30°.

[0056] like Figures 2-4 As shown, the bottom of the dynamic detection station is provided with a wind tunnel structure 128 and a blowing module 130. The blowing module 130 blows air into the wind tunnel structure 128 from bottom to top, and the shuttlecock is suspended and rotating when it is located inside the wind tunnel structure 128. A clamping and feeding component 126 for transferring the shuttlecock from the feeding seat 110 to the wind tunnel structure 128 is provided between the dynamic detection station and the rotary table 109. A baffle structure 127 is provided above the clamping part of the clamping and feeding component 126.

[0057] When the feeding seat 110 carries the shuttlecock to the side of the dynamic detection station, the second feeding component 126 (such as a pneumatic gripper) clamps the head of the shuttlecock, transfers it to the top of the air duct structure 128 and releases it; during the transfer, the baffle structure 127 covers the clamping part to prevent the shuttlecock from flying out of the second feeding component 126 due to the airflow inside the air duct when it just enters the air duct structure 128.

[0058] Based on the above scheme, the clamping and feeding component 126 transfers the badminton shuttlecock, after visual inspection, into the air duct structure 128. The blowing module 130 (such as a centrifugal fan) blows air upwards from the bottom of the air duct, forming a stable updraft field. The badminton shuttlecock is suspended in the air and rotates naturally under the action of the airflow to simulate the actual flight state. During the rotation, dynamic parameters such as the swing amplitude and rotation speed of the badminton shuttlecock are captured in real time. By simulating the actual flight environment of the badminton shuttlecock through updraft, the problem that static detection cannot reflect dynamic performance is avoided.

[0059] Two air duct structures 128 are configured, and the two air duct structures 128 are mounted on the same rotating base 129 and located on both sides of the rotation center. The rotating base 129 drives the air duct structures 128 to switch between the unloading station and the dynamic inspection station. When one air duct structure 128 is being inspected at the dynamic inspection station, the other air duct structure 128 is unloading the shuttlecock after inspection. The rotating base 129 (e.g., driven by a servo motor) drives the two air duct structures 128 to alternately switch between the dynamic inspection station and the unloading station.

[0060] like Figure 8 As shown, the dynamic detection station includes a camera 124 and a light source 125 located below the camera 124. The light source 125 is a ring light source. The camera 124, the light source 125, and the air duct structure 128 are concentrically arranged. The camera 113 shoots vertically downwards. When the badminton shuttlecock is suspended and rotating inside the air duct, the light source 125 illuminates the shuttlecock evenly, and the camera 124 shoots vertically downwards. By continuously shooting multiple frames, the rotation trajectory of the badminton shuttlecock is recorded to determine whether it meets the dynamic performance standard.

[0061] like Figures 9-10As shown, the feeding auxiliary device 200 includes a feeding channel 201, a nozzle structure 202 located directly below the feeding channel 201 and connected to an air source, and a baffle plate 203 for blocking the nozzle structure 202. Several feeding components pass sequentially between the nozzle structure 202 and the feeding channel 201. A telescopic component is connected to the baffle plate 203. The telescopic component drives the baffle plate 203 to move closer to or away from the nozzle structure 202. When a shuttlecock enters the feeding channel 201, the air blowing mechanism blows air to straighten the shuttlecock. As the shuttlecock continues to fall, the telescopic component drives the baffle assembly to move onto the nozzle to block the nozzle structure 202.

[0062] In the above scheme, after the badminton shuttlecock is unloaded from the dynamic detection station, it enters the unloading channel 201. At this time, the telescopic component moves the baffle 203 away from the nozzle structure 202. The nozzle structure 202, connected to the compressed air source, blows air, and the airflow acts on the badminton shuttlecock from below, straightening the tilted shuttlecock. This process takes about 2 seconds. Then, the telescopic component moves the baffle 203 to the nozzle structure 202 to block the airflow and prevent airflow interference, allowing the badminton shuttlecock to fall vertically into the loading component. The air-blowing straightening design can solve the problem of the badminton shuttlecock's tilted unloading posture causing it to not fall accurately into the loading component, thus improving the unloading success rate.

[0063] The baffle 203 is larger than the air outlet of the mouthpiece structure 202, ensuring complete coverage of the air outlet when blocked. The telescopic component includes a telescopic cylinder 204, and the baffle 203 is fixed to the output end of the telescopic cylinder 204. The feeding channel 201 has a bucket-shaped structure, through which badminton shuttlecocks falling into the material-carrying ring 306. The bucket-shaped feeding channel 201 can guide the falling path of the badminton shuttlecocks, ensuring accurate feeding position.

[0064] like Figures 11-14 As shown, the sorting and conveying device 300 includes a conveyor unit, a receiving component located on one side of the conveyor unit, and a discharging component corresponding to the receiving component; the conveyor unit is provided with a plurality of loading components for placing badminton shuttlecocks at intervals, the receiving component includes a plurality of inclined receiving chutes 307, and the discharging component pushes badminton shuttlecocks of the corresponding grade into the corresponding receiving chutes 307, and the badminton shuttlecocks entering the same receiving chutes 307 are arranged in a single row stacked arrangement.

[0065] Qualified shuttlecocks are assisted by the unloading auxiliary device 200 and fall into the material carrier of the conveyor unit. The conveyor unit moves the material carrier, and the testing host 101 determines the grade of the shuttlecocks based on the test results. In this scheme, the shuttlecocks can be divided into 13 grades, and they are arranged in descending order of grade during unloading. Each receiving chute 307 receives one grade of shuttlecock. When the material carrier moves to the receiving chute 307 of the corresponding grade, the unloading component pushes the shuttlecock into the receiving chute 307. The shuttlecock slides down the inclined chute and is arranged in a single row (naturally stacked by gravity).

[0066] This solution enables automatic sorting of badminton shuttlecocks of different grades, eliminating the need for manual sorting, thus improving sorting efficiency. The single-row stacking arrangement prevents the shuttlecocks from piling up messily after sorting, reducing manual handling. At the same time, the tilted chute reduces the speed at which the shuttlecocks fall, preventing damage from collisions.

[0067] The conveyor unit includes an inclined conveyor frame 301, a drive mechanism 302, a conveyor belt 303, and a belt support plate 304 for supporting the conveyor belt 303. The loads are installed at intervals on the conveyor belt 303. The drive mechanism 302 (such as a geared motor) drives the conveyor belt 303 to move along the inclined conveyor frame 301. The belt support plate 304 supports the conveyor belt 303 to prevent the belt from sagging due to the weight of the loads. The loads are installed at intervals on the conveyor belt 303 and move synchronously with the belt, conveying badminton shuttlecocks to the corresponding receiving chute 307.

[0068] The material carrier includes a material carrier bracket 305 and a material carrier ring 306 mounted on the material carrier. Shuttlecocks falling from the discharge channel 201 enter the material carrier ring 306. The inner diameter of the material carrier ring 306 is smaller than the maximum diameter of the shuttlecock. As the shuttlecock falls from the discharge channel 201 into the material carrier ring 306, because the inner diameter of the material carrier ring 306 is smaller than the maximum diameter of the shuttlecock feathers, the feathers are held in place above the material carrier ring 306, with the shuttlecock head facing downwards, preventing contact and friction between the feathers and the conveyor belt 303. The material carrier bracket 305 secures the material carrier ring 306, ensuring no shaking when moving with the conveyor belt 303.

[0069] The feeding assembly includes a plurality of feeding cylinders 309 corresponding one-to-one with the receiving chute 307 and feeding push blocks 310 installed at the output end of the feeding cylinders 309. The push blocks push the shuttlecocks from top to bottom. When the loading component moves the shuttlecock to the side of the corresponding receiving chute 307, the corresponding feeding cylinder 309 drives the feeding push block 310 to move downward. The push block acts on the head of the shuttlecock, pushing the shuttlecock out of the loading ring 306 and into the receiving chute 307. After the pushing is completed, the feeding cylinder 309 drives the push block to reset, waiting for the next shuttlecock.

[0070] The inclination of several receiving chutes 307 is the same, and the height of several receiving chutes 307 increases from bottom to top. The cross-section of the receiving chutes 307 is semi-circular, and a blocking structure 308 is provided at the end of the receiving chutes 307 away from the unloading component. The inner surface of the receiving chutes 307 is a smooth surface.

[0071] In the above scheme, the receiving chutes 307 of different grades are arranged sequentially by height, with each receiving chute 307 corresponding to a different grade; for example, the higher the height, the higher the grade. The shuttlecock slides down the inclined chutes. The semi-circular cross-section conforms to the contour of the shuttlecock feathers, preventing the feathers from being scratched by the edge of the chutes. The smooth inner surface, such as through polishing, reduces the resistance to the shuttlecock's descent. The blocking structure 308 prevents the shuttlecock from sliding out of the end of the chutes. Finally, the shuttlecocks are stacked in a single row within the chutes, and the stacked shuttlecocks can be manually removed.

[0072] Based on the above overall plan, it can be seen that in the inspection stage, through the division of labor and cooperation of the three workstations for appearance inspection, and with the help of multiple cameras and multiple light sources, more than ten kinds of appearance defects such as uneven gaps, broken rods, and missing rods can be accurately identified; dynamic inspection uses the 128-type wind tunnel structure to simulate the actual flight environment, combined with the dynamic inspection workstation, to prevent products that are qualified in appearance but have abnormal flight from entering the market.

[0073] Meanwhile, in the conveying and sorting stages, the air-blowing and straightening structure of the unloading auxiliary device 200 can improve the success rate of unloading without contacting the shuttlecocks; multiple sets of receiving chutes 307 are arranged in an orderly manner according to grade, and with the design of a semi-circular cross section and a smooth inner surface, they can not only achieve orderly storage of shuttlecocks stacked in a single row, eliminating the need for manual sorting, but also prevent the feathers from being scratched during conveying. The overall solution is adapted to the needs of large-scale production, achieving a dual improvement in detection accuracy and production efficiency.
