Description

Technical Field

[0001] This invention relates to the field of steel ball detection equipment technology, and specifically to an automatic steel ball detection device. Background Technology

[0002] In industrial fields that rely on steel balls, such as bearing manufacturing and precision instrument assembly, the surface quality (such as scratches, rust, and pits) and geometric accuracy of the steel balls are the core factors that determine the performance and reliability of the final product. Therefore, it is crucial to achieve efficient and comprehensive factory testing of them.

[0003] Traditional manual sampling methods suffer from low efficiency, poor consistency, and susceptibility to fatigue-induced omissions, and are unable to meet the modern production requirements of full inspection and quality data traceability. While existing automated equipment has partially solved these problems, it still has limitations. For example, a steel ball detection and sorting device disclosed in Chinese Patent No. CN107262384A uses a pressure sensor, a pneumatic gauge, and a flaw detector to simultaneously analyze the weight, size, and internal structure of the steel balls, achieving multi-parameter integrated detection and classification. However, this device fixes the steel balls in the clamping part during the detection process, keeping them stationary or only allowing single-angle imaging. This static detection mode prevents the complete imaging of the ball surface, and the equatorial and bottom regions in contact with the clamping structure cannot be observed, creating unavoidable detection blind spots. This can lead to missed local defects, limiting the reliable application of this technology in high-precision scenarios.

[0004] To address the aforementioned problems, this invention proposes an automatic steel ball detection device. Summary of the Invention

[0007] Furthermore, the kinetic energy application part includes a guide rod, one end of which is fixedly connected to the detection carrier, and the other end of which is provided with a kinetic energy application member.

[0010] Furthermore, it also includes a pole, on which the high-definition detection camera is mounted, and the detection support is fixedly connected to the surface of the pole and located below the high-definition detection camera.

[0011] Furthermore, it also includes a feeding assembly, which includes a bracket, a conveying trough fixedly connected to the top of the bracket, a guide rod whose end away from the detection bearing is fixedly connected to the conveying trough, and the two are connected through a through-hole, a kinetic energy application member is installed on the outer wall of the conveying trough, and the movable end of the kinetic energy application member moves along the length direction of the guide rod, and a receiving tray with an inwardly contracting outlet is fixedly connected to the end of the conveying trough away from the guide rod, and the conveying trough and the receiving tray as a whole are inclined downward toward the guide rod.

[0013] Furthermore, it also includes a sorting assembly, which includes a column, a rack slot fixedly connected to the top of the column, a movable channel rotatably connected to one side of the top of the rack slot, a fixed channel fixedly connected to the other side of the top of the rack slot, a sorting push rod rotatably connected inside the rack slot, the output end of the sorting push rod rotatably connected to the outlet end of the movable channel, a waste pipe fixedly connected to the bottom of the rack slot, and when the movable channel and the fixed channel are connected, the two together are inclined downward toward the fixed channel.

[0019] The following is in conjunction with the appendix Figure 1-8 The present invention is further illustrated by the embodiments: like Figure 1-8 As shown, an automatic steel ball detection device includes: a detection unit, which includes a high-definition detection camera 1 for imaging the surface of the steel ball; a detection carrier 2, disposed below the shooting area of ​​the high-definition detection camera 1, and having an internal movable chamber 21 for the steel ball to be detected to roll autonomously; and a kinetic energy application part 3, disposed on one side of the detection carrier 2, for applying kinetic energy to the steel ball to be detected, so that the steel ball rolls in the movable chamber 21 without external clamping constraints, so that the high-definition detection camera 1 can capture multi-angle images of its surface.

[0020] Specifically, a detection unit is set up to acquire images of the steel ball surface; a detection carrier 2 and a movable chamber 21 are set up to provide a space for the steel ball to roll autonomously; and a kinetic energy application unit 3 is set up to drive the steel ball to roll freely within this space without external clamping. During operation, the kinetic energy application unit 3 applies kinetic energy to the steel ball, enabling it to roll freely within the movable chamber 21. The high-definition detection camera 1 is preferably a high-speed industrial camera, which continuously captures or triggers images during the rolling process of the steel ball to acquire image sequences of different parts of its surface. This achieves multi-angle, blind-spot-free surface imaging of the steel ball in motion, solving the visual blind spot problem existing in static clamping detection methods, thereby improving the detection rate of surface defects and the comprehensiveness of the detection results.

[0021] The kinetic energy application unit 3 includes a guide rod 31. One end of the guide rod 31 is fixedly connected to the detection carrier 2, and the other end of the guide rod 31 is provided with a kinetic energy application member 32. The kinetic energy application member 32 can drive its movable end to make linear motion to push the steel ball through the guide rod 31 into the movable chamber 21. The kinetic energy application member 32 can be an electromagnet, a linear cylinder, or an electric push rod. During operation, its movable end extends rapidly, applying an instantaneous pulse thrust to the single steel ball located at the inlet end of the guide rod 31. By setting the guide rod 31 to form a path from the feeding point to the detection chamber, the linear drive of the kinetic energy application member 32 can provide an initial thrust, enabling the steel ball to be accurately and reliably pushed into the movable chamber 21 along a predetermined path, ensuring the consistency of the starting position and state of each detection, and improving the automation of the detection process.

[0022] The detection carrier 2 includes a mounting base 22, with a tray 23 at its bottom. The mounting base 22 has an opening corresponding to the tray 23. The movable chamber 21 is formed by the inner cavity of the tray 23 and the opening. An inlet channel 24 communicating with the movable chamber 21 is provided on the mounting base 22, and a guide rod 31 connects to the inlet channel 24. By setting up the mounting base 22, the tray 23, and the movable chamber 21 formed by them, a local environment is provided for the rolling detection of the steel ball. The inner cavity of the tray 23 encloses the steel ball, limiting its range of motion while ensuring sufficient rolling. The connection between the inlet channel 24 and the guide rod 31 ensures a smooth transition of the steel ball from the conveying stage to the detection stage, reducing the risk of jamming or deflection.

[0023] The bottom of the mounting base 22 has a cavity. The tray 23 is rotatably connected to the inner wall of the cavity via a rotating shaft. A drive motor 25 is fixedly connected to the outer wall of the mounting base 22, and the output end of the drive motor 25 is connected to the rotating shaft. A tapered discharge port 231 is formed on one side of the tray 23, and a blocking part 26 is formed on one side of the mounting base 22 to prevent steel balls from slipping out of the tray 23. After the inspection is completed, the drive motor 25 rotates at a specific angle, causing the tray 23 to tilt, with its discharge port 231 aligned with the inlet of the downstream sorting component 6. At this time, the steel balls roll out under the action of gravity. Subsequently, the drive motor 25 reverses, causing the tray 23 to return to the horizontal inspection position, and the blocking part 26 resumes its limiting function. By setting the drive motor 25 to rotate the tray 23 to the tilted state, the automatic unloading and flow control of the steel balls after inspection are achieved. The drive motor 25 can precisely control the flipping angle of the tray 23, so that the tested steel balls can slide out from the discharge port 231 according to the instructions, while the blocking part 26 effectively prevents the steel balls from rolling down accidentally during the testing period, thereby seamlessly connecting the testing station with the subsequent sorting process and improving the overall automation and intelligence level of the device.

[0024] It also includes a support pole 4, on which the high-definition inspection camera 1 is mounted. The inspection support component 2 is fixedly connected to the surface of the support pole 4 and located below the high-definition inspection camera 1. By setting up the support pole 4, a stable mounting base is provided for the high-definition inspection camera 1 and the inspection support component 2, ensuring the stability of the imaging optical path and the accuracy of the spatial position of the inspection station.

[0025] The system also includes a feeding assembly 5, which comprises a support 51. A conveying trough 52 is fixedly connected to the top of the support 51. The end of the guide rod 31 away from the detection bearing 2 is fixedly connected to the conveying trough 52, and the two are connected through a through-hole. A kinetic energy application member 32 is installed on the outer wall of the conveying trough 52, and the movable end of the kinetic energy application member 32 moves along the length of the guide rod 31. A receiving tray 53 with an inwardly contracting outlet is fixedly connected to the end of the conveying trough 52 away from the guide rod 31. The conveying trough 52 and the receiving tray 53 are inclined downward toward the guide rod 31. By setting up the feeding assembly 5, automatic and continuous supply of steel balls is achieved. The inclined conveying trough 52 uses gravity to assist feeding, reducing energy consumption; the constricting design of the receiving tray 53 can guide and organize the steel balls; the entire feeding path finally connects with the guide rod 31, forming a material flow from collection, conveying to pushing, improving the feeding efficiency and continuous operation capability of the device.

[0026] The feeding assembly 5 also includes a stand 54, within which a feeding pipe 55 is rotatably connected. An inlet pipe 56 is fixedly connected to the outer wall of the feeding pipe 55. A feeding push rod 57 is rotatably connected to the bottom of the stand 54, and the output end of the feeding push rod 57 is rotatably connected to the outlet end of the feeding pipe 55. This is used to achieve the directional and orderly supply of steel balls. The feeding push rod 57 can periodically extend and retract, driving the feeding pipe 55 to oscillate back and forth around its hinge point with the stand 54. By setting the feeding push rod 57 to drive the feeding pipe 55 to oscillate periodically, the steel balls entering the feeding pipe 55 from the inlet pipe 56 move along the feeding pipe 55 under the action of gravity to the outlet end and fall orderly into the receiving tray 53.

[0027] The system also includes a sorting component 6, which comprises a column 61. A frame groove 62 is fixedly connected to the top of the column 61. A movable channel 63 is rotatably connected to one side of the top of the frame groove 62, and a fixed channel 64 is fixedly connected to the other side of the top of the frame groove 62. A sorting push rod 65 is rotatably connected inside the frame groove 62. The output end of the sorting push rod 65 is rotatably connected to the outlet end of the movable channel 63. A waste pipe 66 is fixedly connected to the bottom of the frame groove 62. When the movable channel 63 and the fixed channel 64 are connected, both are inclined downwards towards the fixed channel 64. By setting up the sorting component 6, steel balls can be sorted in real time and automatically based on image detection results. When the image processing system determines that a steel ball is defective, the sorting push rod 65 is activated when the corresponding steel ball arrives at the sorting station, pulling the movable channel 63 downwards and rotating it. The defective product is then guided into the waste pipe 66. For qualified products, the sorting push rod 65 remains stationary, and the movable channel 63 remains raised under the action of the sorting push rod 65. At this time, the steel ball falls directly into the fixed channel 64. This achieves online, non-contact, rapid sorting, improving screening efficiency and accuracy.

[0028] It also includes a recycling component 7, which comprises a conveyor belt unit 71. Multiple material bins 72 are fixedly connected to the surface of the conveyor belt body 711 of the conveyor belt unit 71, and a receiving hopper 73 is fixedly connected to one end of the conveyor belt unit 71 near the fixed channel 64. This achieves automatic collection, arrangement, and conveying of qualified steel balls. The outlet of the fixed channel 64 is aligned with the receiving hopper 73. After qualified steel balls fall into the receiving hopper 73, they slide into a material bin 72 of the running conveyor belt body 711 below, and are carried away sequentially, achieving individual separation and conveying. This realizes the material handling process after inspection, achieving a fully automated closed-loop operation from inspection, sorting to collection.

[0029] In this embodiment, the device also includes a control system (not shown in the figure) electrically connected to the high-definition detection camera 1, the kinetic energy application element 32, the drive motor 25, the feeding pusher 57, the sorting pusher 65, and the conveyor belt unit 71. This control system coordinates the actions of each component according to a preset program sequence and issues sorting instructions based on image processing results.

[0030] Working principle: When the automatic steel ball detection device is in use, firstly, the control system and conveyor belt unit 71 are started, putting the device into standby mode. The operator uses an external robotic arm or other feeding equipment to pour the steel balls to be tested in batches into the inlet pipe 56 of the feeding assembly 5. The control system controls the extension and retraction of the feeding push rod 57 according to a preset cycle, driving the feeding pipe 55 to swing back and forth. Under the action of gravity, the steel balls fall from the outlet end of the feeding pipe 55 into the receiving tray 53 along the inclined direction of the feeding pipe 55. Subsequently, the steel balls automatically roll down along the inclined receiving tray 53 and the conveying trough 52 to the bottom, that is, the inlet of the guide rod 31.

[0031] Next, the control system triggers the action of the kinetic energy application unit 3: the movable end of the kinetic energy application member 32 extends rapidly, applying a precise pulse thrust to the single steel ball stationary at that position. The steel ball is pushed into the guide rod 31 and moves along its inner cavity, finally being sent into the tray 23 of the detection carrier 2 through the inlet channel 24. At this time, the tray 23 is in a horizontal position, with the blocking part 26 on its side preventing the steel ball from rolling out, while the upper opening and the inner cavity of the tray 23 together form an active chamber 21 that allows the steel ball to roll freely.

[0032] As the steel ball rolls continuously within the tray 23 under inertia, the high-definition detection camera 1, triggered by the control system, begins operation, capturing multiple consecutive frames or triggering snapshots of the moving steel ball to obtain an image sequence of the entire surface of the ball. These images are transmitted in real time to the image processing system for analysis, dimensional measurement, surface defect detection, and quality assessment results.

[0033] After image detection is completed, the control system issues a command: the drive motor 25 starts, causing the tray 23 to rotate around the rotating axis by a predetermined angle, tilting it. The tapered discharge port 231 on the tray 23 opens and aligns with the inlet of the downstream sorting component 6. The steel ball rolls out from the discharge port 231 under the action of gravity and falls into the sorting station. Subsequently, the drive motor 25 reverses, causing the tray 23 to quickly return to a horizontal position, ready to receive the next steel ball to be inspected.

[0034] In the sorting process, the control system makes decisions based on the image processing results. If the current steel ball is determined to be defective, the control system activates the sorting push rod 65 the instant the steel ball rolls to the sorting station, pulling the movable channel 63 downward to rotate it downward, so that its outlet faces downward, and the defective steel ball is guided into the waste pipe 66 for collection. If the steel ball is determined to be acceptable, the sorting push rod 65 remains stationary, the movable channel 63 is in the raised state, and the steel ball falls directly into the fixed channel 64.

[0035] Qualified steel balls slide down the fixed channel 64 and fall from its outlet into the receiving hopper 73 of the recycling component 7, and then slide into a material bin 72 on the continuously running conveyor belt body 711 below. The conveyor belt unit 71 transports the material bins 72 carrying steel balls to the designated collection area in sequence, realizing the automatic arrangement, counting and output of qualified products.

[0036] In summary, the entire process operates automatically and continuously under the unified scheduling of the control system, realizing a closed-loop automated operation from automatic feeding, precise positioning, dynamic imaging, real-time analysis, automatic unloading to intelligent sorting and recycling.

[0037] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
