Description

Technical Field

[0001] This invention relates to the field of drill bit inspection technology, specifically to a visual inspection mechanism and inspection method for a full drill bit inspection machine. Background Technology

[0002] Drill bits are core cutting tools in machining, and their appearance quality directly determines machining accuracy and tool life. Traditional inspection relies on manual visual inspection or measuring tools, which suffers from low efficiency, unstable accuracy, high missed inspection rate, and inability to achieve 100% full inspection, making it difficult to adapt to the needs of automated production. With the popularization of machine vision technology, drill bit full inspection machines are gradually adopting optical vision inspection mechanisms to achieve non-contact automatic inspection. The drill bit is transported to the inspection station by a conveyor belt, and the V-shaped guide straightening mechanism corrects the drill bit's posture to ensure that the drill bit axis is coaxial with the rotating spindle, avoiding skew and jamming, laying the foundation for subsequent clamping and imaging. When the drill bit is fed into the clamping station, the drill bit center is aligned to ensure that the drill bit is in the optimal imaging depth of field and optical center of the camera. The strip light source is activated, and the light shines on the drill bit cutting edge. The rotating spindle drives the drill bit to rotate at a uniform speed, achieving coverage without blind spots. The industrial camera, in conjunction with a telecentric lens, continuously acquires high-definition images during the drill bit's rotation through synchronous trigger signals, accurately corresponding to the drill bit's rotation position, and obtaining complete information on the drill bit's appearance and dimensions.

[0003] However, in existing visual inspection mechanisms for full drill bit inspection, when the drill bit is held by only one end of the rotating spindle, a cantilever beam structure is formed. The drill bit is a slender carbide rod with inherent deflection. During high-speed rotation, centrifugal force causes significant radial runout and oscillation at the cutting edge. This runout directly disrupts the stability of optical inspection and is the core cause of blurred images, inaccurate dimensional measurements, overexposure due to reflection, and equipment collisions. Furthermore, the surface of carbide drill bits has specular reflection characteristics. When a light source shines directly on it, it produces strong specular reflection light that directly enters the camera lens, causing local overexposure and whitening of the image. Minor defects such as chipped cutting edges, microcracks, and surface scratches are completely masked, making them unrecognizable by the visual system. Simply weakening the light source brightness cannot solve this problem. Globally darkening the image will result in insufficient overall brightness of the drill bit, increased noise, and further reduced defect contrast, making it even more difficult to detect. The overexposed area remains the brightest part of the image, and the reflection problem remains fundamentally unchanged. This is a passive compromise rather than a fundamental structural solution.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing visual inspection mechanisms and methods used in drill bit full inspection machines. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a visual inspection mechanism and method for a full-inspection drill bit machine to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection mechanism and inspection method for a full inspection machine for drill bits, comprising a main body, wherein multiple supports are fixed at equal intervals on a conveyor belt disposed within the main body, a rotating seat is disposed on one side of the main body, a motor is fixed to one end of the rotating seat, a fixed seat is rotatably connected to the other side of the main body, a base is fixed to one end of the fixed seat, a clamping assembly is disposed at one end of the base, a sliding rod is disposed at one end of the clamping assembly, a contact plate is fixed to one end of the sliding rod, and the clamping assembly drives the contact plate to fix the drill bit, an interval lifting assembly is disposed at the other end of the base, and the interval lifting assembly drives the contact plate to perform interval clamping of the drill bit, a light source is fixed within the main body, a shaking assembly is disposed on both sides of the light source, a light shield is fixed to one side of the shaking assembly, and the shaking assembly drives the light shield to perform small-angle reciprocating fan-shaped swing along the axis of the drill bit, a camera is disposed on one side of the light source, and one end of the camera is fixedly connected to the main body.

[0007] Preferably, the clamping assembly includes a turntable disposed at the top of the base, a motor fixed to one end of the turntable, multiple rotating plates hinged at equal angles to the turntable, sliders hinged to the rotating plates, slide rails slidably connected to the sliders, limit sliding connection between the sliders and slide rods, slide rails slidably connected to the slide rods, and the slide rods pass through the slide rails and the base.

[0008] Preferably, the slide rail is fixedly connected to the base, and both the base and the slide rail have cavities that cooperate with the movement of the slide rod.

[0009] Preferably, the interval lifting assembly includes a gear disposed within the main body, the gear meshing with a gear ring, a rotating ring fixed to the inner wall of the gear ring, a roller slidably connected to the top of the rotating ring, a lifting frame rotatably connected to the roller, a first piston rod fixed to the bottom of one of the lifting frames, a first oil tank slidably connected to the first piston rod, and the first oil tank being fixedly connected to a fixed base.

[0010] Preferably, the rotating ring is composed of a circular ring and two protrusions, the lifting frame is slidably connected to the slide rod, and the lifting frame has a cavity that cooperates with the movement of the slide rod.

[0011] Preferably, a spring is provided between the fixed base and the lifting frame, with one end of the spring fixedly connected to the top of the fixed base and the other end of the spring fixedly connected to the bottom of the lifting frame.

[0012] Preferably, the shaking assembly includes a fixed plate fixed inside the main body, a connecting rod fixed to one side of the fixed plate, a rotating frame rotatably connected to the outer wall of the connecting rod, a guide rod fixed to one side of the rotating frame, a guide plate slidably connected to the outer wall of the guide rod, a second piston rod fixed at a protruding position on one side of the guide plate, and a second oil tank slidably connected to the second piston rod.

[0013] Preferably, one side of the rotating frame is fixedly connected to the light-shielding plate, and the guide plate has a cavity that moves in conjunction with the guide rod, and the cross-section of the cavity is in the shape of a broken line.

[0014] Preferably, the second oil tank is fixedly connected to the main body, and the second oil tank and the first oil tank are connected by a hose.

[0015] A method for using a visual inspection mechanism and inspection method for a drill bit full inspection machine includes the following steps: S1: The drill bit is conveyed to the inspection station via the main conveyor belt support. The robot arm is inserted into the rotating seat and pushes the conical synchronous clamping head. The elastic self-centering sleeve centers and eliminates eccentricity. The motor drives the turntable and other linkages. The contact plate contracts inward, so that the drill bit can be supported at both ends. S2: Activate the bar light source, the rotating seat drives the drill bit to rotate, the linkage contact plate and the fixed seat rotate synchronously, and the camera, with the telecentric lens, continuously collects high-definition images of the drill bit's appearance and size; S3: When the drill bit rotates, the motor drives the gears and other linkages to make the rollers and lifting frame rise and fall intermittently, which in turn drives the slide bar and the contact plate to rise and fall, thus avoiding obstruction and missed detection. S4: The lifting frame moves in conjunction with the first piston rod, oil, and guide components, causing the light shield to swing back and forth at a small angle along the length of the light source, blocking reflections and preventing overexposure.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves automatic centering by feeding the drill bit into the rotating seat, with a conical synchronous clamping head and an elastic self-centering sleeve. The motor drives the turntable and rotating plate in linkage, and the slider slides radially along the slide rail, causing the slide rod and the contact plate to contract centripetally. The slide rod moves through the base guide, eliminating the initial eccentricity and rotational runout of the drill bit, ensuring that the drill bit is coaxial with the optical center, and preventing the single-end clamping of the drill bit as a cantilever beam structure. The rotation of the slender carbide rod is prone to radial runout, causing blurred imaging, inaccurate dimensional measurement, and equipment collision. The imaging is clear and stable, adapting to drill bits of different diameters and lengths, improving the versatility of the equipment, avoiding drill bit swinging and collision with optical components, and extending the service life of the equipment.

[0017] 2. This invention uses a motor to drive a gear, gear ring, and rotating ring to rotate. The rotating ring's protrusions alternately act on the rollers, causing the lifting frame to rise and fall intermittently. A spring assists in resetting the frame, and the lifting frame drives the sliding rod and the contact plate to rise and fall synchronously. The contact plate continuously clamps the drill bit, which can obstruct local surfaces, leading to missed defects such as chipped cutting edges and microcracks, making it impossible to achieve 360° full inspection. By changing the contact plate to intermittent avoidance, the clamping area is avoided from obstructing the view, achieving full circumferential imaging of the drill bit without blind spots, significantly reducing the defect missed rate and improving the integrity of the inspection.

[0018] 3. This invention uses a lifting frame to drive the first piston rod to reciprocate within the first oil tank. The oil, transmitted through a hose, drives the second piston rod and guide plate to move. The zigzag cavity causes the guide rod and rotating frame to sway. The light-shielding plate swings in a fan shape along the length of the light source, preventing overexposure of the image caused by specular reflection from the carbide drill bit. Defects are concealed, and simply weakening the light source can lead to insufficient image brightness and reduced defect contrast. This invention dynamically blocks strong specular reflection, eliminating overexposure at its source. It does not affect normal lighting brightness, and the defect outline is clearly discernible. Pure oil-based linkage requires no additional drive, resulting in a compact structure and strong motion synchronization. Attached Figure Description

[0028] As a further embodiment of the present invention, the interval lifting assembly includes a gear 901 disposed in the main body 1, the gear 901 meshing with a gear ring 902, a rotating ring 903 fixed on the inner wall of the gear ring 902, a roller 904 slidably connected to the top of the rotating ring 903, and a lifting frame 905 rotatably connected to the roller 904.

The first oil tank 906 is fixedly connected to the fixed base 4.

[0029] In specific implementation, the gear 901 drives the meshing gear ring 902 and rotating ring 903 to rotate, which drives the roller 904 that is in sliding cooperation with it to lift the lifting frame 905 up and down. The lifting frame 905 drives the first piston rod 907 to slide within the first oil tank 906 that is fixed to the fixed seat 4.

[0034] As a further embodiment of the present invention, the shaking component includes a fixed plate 111 fixed inside the main body 1, a connecting rod 112 fixed to one side of the fixed plate 111, a rotating frame 113 rotatably connected to the outer wall of the connecting rod 112, a guide rod 114 fixed to one side of the rotating frame 113, a guide plate 115 slidably connected to the outer wall of the guide rod 114, a second piston rod 116 fixed at a protruding position on one side of the guide plate 115, and a second oil tank 117 slidably connected to the second piston rod 116.

The guide rod 114 on the rotating frame 113 is slidably engaged with the guide plate 115.

[0040] A method for using a visual inspection mechanism and inspection method for a drill bit full inspection machine includes the following steps: S1: The drill bit is conveyed to the inspection station via the main body 1 and the conveyor belt bracket 2. The robot arm is inserted into the rotating seat 3, pushing the conical synchronous clamping head. The elastic self-centering sleeve centers and eliminates eccentricity. The motor drives the turntable 601 and other linkages. The contact plate 8 retracts inward, so that the drill bit can be supported at both ends. S2: Start the strip light source, rotate the seat 3 to drive the drill bit to rotate, and link the contact plate 8 and the fixed seat 4 to rotate synchronously. The camera 13, in conjunction with the telecentric lens, continuously collects high-definition images of the drill bit's appearance and size. S3: When the drill bit rotates, the motor drives the gear 901 and other linkages to make the roller 904 and the lifting frame 905 rise and fall intermittently, which in turn drives the slide bar 7 and the contact plate 8 to rise and fall, thus avoiding obstruction and missed detection. S4: The lifting frame 905 moves in conjunction with the first piston rod 907, oil and guide components, causing the light shield 12 to swing back and forth at a small angle along the length of the light source, blocking reflection and preventing overexposure.

[0041] Working principle: When using the visual inspection mechanism and method of this drill bit full inspection machine, the drill bit is transported to the inspection station via the bracket 2 installed on the conveyor belt of the main body 1. The robot arm inserts the drill bit into the rotating seat 3. The shank set inside the rotating seat 3 pushes the conical synchronous clamping head, compresses the axial return spring, drives the elastic self-centering sleeve to retract radially, automatically aligns the drill bit center, eliminates the initial eccentricity, and ensures that the drill bit rotation axis remains coaxial with the inspection optical center. The motor is started, which drives the turntable 601 to rotate, thereby driving the multiple rotating plates 602 that are hinged at the same angle to the turntable 601 synchronously. The rotation causes the slider 603, which is hinged to the rotating plate 602, to slide radially along the slide rail 604. Since the slider 7 passes through the slider 603 and the slider 7 is fixedly connected to the contact plate 8, the contact plate 8, which is set at equal angles, contracts centripetally, causing the drill bit to change from a cantilever state to a state supported at both ends. The clamping range can be adaptively adjusted to accommodate the clamping and positioning requirements of drill bits with different diameters and lengths. When the slider 7 moves with the slider 603, it slides in the inner cavity of the slide rail 604 and moves synchronously in the inner cavity of the base 5 fixed at the bottom of the slide rail 604, ensuring that the overall movement is smooth and without jamming. After clamping and positioning are completed, the strip light source 10 is activated, illuminating the drill bit's cutting edge. The rotating seat 3 drives the drill bit to rotate at a constant speed. Because the fixed seat 4 and the main body 1 are in a limiting rotational fit, the drill bit rotates synchronously through friction, causing the contact plate 8 and the fixed seat 4 to rotate synchronously. This allows the drill bit to achieve a complete 360° rotation while clamped, ensuring that the light source 10 provides comprehensive illumination of the drill bit's cutting edge, cutting surface, and circumferential appearance without any blind spots. The camera 13, in conjunction with the telecentric lens, continuously captures high-definition images during the drill bit's rotation through a synchronous trigger signal, accurately corresponding to the drill bit's rotation position and obtaining complete information on the drill bit's appearance and dimensions. Simultaneously with the drill bit's rotation, the motor is activated, driving the gear 901 to rotate, which in turn drives the meshing gear ring 902 to rotate. This causes the rotating ring 903, which is fixed to the gear ring 902, to rotate. Since the rotating ring 903 is composed of a circular ring and two protrusions, its end face... The rollers 904 are in sliding engagement. When the rotating ring 903 rotates, the protrusion and the ring segment act alternately on the rollers 904, causing the two sets of rollers 904 to produce intermittent lifting and lowering movements. The rollers 904 are rotatably connected to the lifting frame 905, thereby driving the lifting frame 905 to achieve intermittent lifting and lowering synchronously. During the movement of the lifting frame 905, the spring between it and the fixed seat 4 is compressed or stretched accordingly. The spring elastic force is used to achieve the follow-up reset of the lifting frame 905, ensuring continuous and stable movement. The lifting frame 905 and the slide rod 7 are in a limiting sliding engagement, so that the slide rod 7 and the contact plate 8 achieve intermittent lifting and lowering displacement synchronously (the slide rod 7 is lifting and lowering, and it is limited to sliding within the slider 603). During the auxiliary clamping and rotation of the drill bit, the contact plate 8 avoids long-term blocking of the local surface of the drill bit through intermittent contact avoidance, preventing the blocked area from being imaged and causing defects to be missed, thus improving the integrity of the inspection. When the lifting frame 905 moves up and down, the first piston rod 907 fixed at its bottom end reciprocates synchronously within the first oil tank 906, squeezing or drawing the oil inside the first oil tank 906. The oil is stably transported to the second oil tank 117 through a hose, pushing the second piston rod 116 to extend outward or retract inward. The second piston rod 116 drives the fixed guide plate 115 to move synchronously in a straight line. Because the zigzag guide cavity on the guide plate 115 moves with the displacement, it drives the guide rod 1 inside. 14 swings back and forth along the broken line trajectory, thereby driving the rotating frame 113, which is fixed to the guide rod 114, to swing back and forth at a small angle around the connecting rod 112. The fixed plate 111 is fixedly installed with the main body 1, and the light shield 12 is rigidly connected to the rotating frame 113. Finally, the light shield 12 swings back and forth in a small angle along the axis of the drill bit during the rotation of the drill bit, between the light source 10 and the drill bit, dynamically blocking the strong light reflected by the mirror surface of the drill bit, avoiding overexposure of the image, while not affecting normal lighting and shooting field of view.

8. The visual inspection mechanism for a drill bit full inspection machine according to claim 7, characterized in that: The rotating frame (113) is fixedly connected to the light shield (12) on one side, and the guide plate (115) has a cavity that moves in conjunction with the guide rod (114), and the cross section of the cavity is in the shape of a broken line.

9. The visual inspection mechanism for a drill bit full inspection machine according to claim 7, characterized in that: The second oil tank (117) is fixedly connected to the main body (1), and the second oil tank (117) is connected to the first oil tank (906) through a hose.

10. A method of using a visual inspection mechanism for a drill bit full inspection machine, applicable to the visual inspection mechanism for a drill bit full inspection machine as described in any one of claims 1-9, the method comprising the following steps: S1: The drill bit is conveyed to the inspection station via the main body (1) and the conveyor belt bracket (2). The robot arm is inserted into the rotating seat (3), pushes the conical synchronous clamping head, the elastic self-centering sleeve centers and eliminates eccentricity, the motor drives the turntable (601) and other linkages, the contact plate (8) contracts inward, so that the drill bit can be supported at both ends. S2: Start the strip light source, rotate the seat (3) to drive the drill bit to rotate, and link the contact plate (8) and the fixed seat (4) to rotate synchronously. The camera (13) works with the telecentric lens to continuously collect high-definition images of the drill bit's appearance and size. S3: When the drill bit rotates, the motor drives the gear (901) and other linkages to make the roller (904) and lifting frame (905) rise and fall intermittently, which in turn drives the slide bar (7) and the contact plate (8) to rise and fall, thus avoiding obstruction and missed detection. S4: The lifting frame (905) moves in conjunction with the first piston rod (907), oil and guide components, causing the light shield (12) to swing back and forth at a small angle along the length of the light source, blocking reflection and preventing overexposure.
