Description

Technical Field

[0001] This utility model relates to the technical field of workpiece inspection equipment, and more specifically, to an inspection and sorting machine. Background Technology

[0002] As a core component of mechanical transmission systems, the machining accuracy and surface quality of cemented carbide gears directly affect the operating efficiency, service life, and safety of the equipment. Common machining defects such as tooth surface cracks, chipping, and dimensional deviations can lead to transmission failure, abnormal equipment wear, and even major accidents. Traditional inspection methods rely on manual visual inspection or contact measurement, which suffer from low efficiency, high subjectivity, easy omissions, and visual fatigue for inspection personnel.

[0003] Existing technology discloses an inspection device that, through the arrangement of an image controller, a work platform, a glass turntable, a camera inspection station, a material box, an air blowing mechanism, a vibrating plate, and a rotating motor, can achieve automatic material feeding, automatic inspection, and, after inspection, automatic identification and sorting of good and defective products, automatically distinguishing between good and defective products, while simultaneously completing automatic product counting. However, in the under-view inspection station used in this device to inspect the lower end face of the parts to be inspected, the under-view lens is located below the glass turntable, and its overall length is limited by the space below the glass turntable, making it inconvenient to disassemble and maintain the under-view lens, and also reducing space utilization. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology where the overall length of the upward-looking lens is limited by the space below the glass turntable, and to provide an inspection and sorting machine in which the overall length of the lower end inspection mechanism is not limited by the space below the glass turntable, making it easier to disassemble and maintain the upward-looking lens, while improving space utilization.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A sorting and inspection machine is provided, comprising a frame and a transparent turntable mechanism, a vision inspection mechanism, and a material unloading and sorting mechanism, all mounted on the frame. The vision inspection mechanism includes a lower end face inspection mechanism, a side inspection mechanism, and an upper end face inspection mechanism, all mounted on the frame. The lower end face inspection mechanism includes a lower end face imaging mechanism and a reflective component, all mounted on the frame. The reflective component is located below the transparent turntable mechanism, with its incident surface facing the transparent turntable mechanism and its exit surface facing the lower end face imaging mechanism. The incident surface and the exit surface have an offset angle.

[0006] This utility model's inspection and sorting machine, when inspecting parts, places the parts on a transparent turntable mechanism. Activating the turntable mechanism moves the parts to a vision inspection mechanism. The vision inspection mechanism includes a lower surface inspection unit that visually inspects the lower surface of the part, a side inspection unit that visually inspects the sides of the part, and an upper surface inspection unit that visually inspects the upper surface. After the visual inspection is complete, the turntable mechanism sends the parts to a sorting and unloading mechanism, which sorts and unloads them based on the inspection results. During the visual inspection of the lower surface of the part, the image of the part is reflected by a reflective component through the transparent turntable mechanism and then imaged onto the lower surface imaging mechanism. By using a reflective component, the image of the part is reflected by the reflective component through the transparent turntable mechanism and then imaged onto the lower surface imaging mechanism. The lower surface imaging mechanism does not need to be directly facing the transparent turntable mechanism, allowing its overall length to be unrestricted by the space below the glass turntable. This facilitates disassembly and maintenance of the lower surface imaging mechanism and improves space utilization.

[0007] Furthermore, the reflective assembly includes a reflective mounting bracket, a mounting box, and a reflective prism. The reflective mounting bracket is mounted on the frame, the mounting box is mounted on the reflective mounting bracket, and the reflective prism is disposed within the mounting box. The mounting box has an inlet and an outlet, with the inlet surface facing the inlet and the outlet surface facing the outlet. The reflective prism is located within the mounting box, which is mounted on the frame via the reflective mounting bracket. The image of the part is reflected by the reflective prism through the inlet to the outlet, where it is imaged into the lower end-face imaging mechanism.

[0008] Furthermore, the reflecting prism is configured as a total internal reflection prism, and the inner diameters of the entrance and exit ports are not less than the outer diameter of the part to be inspected. This ensures that the part is clearly imaged in the lower end face imaging mechanism.

[0009] Furthermore, the reflective assembly also includes a first fastener. The mounting box is rotatably connected to the reflective mounting frame, and the mounting box can be fixed to the reflective mounting frame by the first fastener. The imaging angle of the reflective prism is adjusted by rotating the mounting box. After adjustment, the position of the mounting box is fixed by the first fastener to ensure that the part is clearly imaged in the lower end face imaging mechanism.

[0010] Furthermore, the reflective mounting bracket includes a connecting frame, a first connecting plate, and a second connecting plate. The connecting frame is mounted on the frame, and the first and second connecting plates are respectively located at both ends of the connecting frame. The first connecting plate has a rotating groove, and the mounting box has a rotating rod for rotatably connecting with the rotating groove. The first fastener is a bolt, and the second connecting plate has a mounting hole in which the bolt is located. The mounting box has a threaded hole for threaded connection with the bolt. When the mounting box is rotated, the rotating rod rotates within the rotating groove. After rotation, the first fastener is threaded into the threaded hole to fix the mounting box.

[0011] Furthermore, the first connecting plate is equipped with a pointer, and the mounting box is equipped with an angle scale. When the mounting box is rotated, the pointer points to different angle scales, thus allowing for clear and intuitive observation of the adjusted angle.

[0012] Furthermore, the lower end face detection mechanism also includes a semi-annular light source, which is mounted on the frame and located between the reflective component and the transparent turntable mechanism. By setting the semi-annular light source, the light source is more closely aligned with the imaging path, further ensuring that the part is clearly imaged in the lower end face imaging mechanism.

[0013] Furthermore, the lower end face imaging mechanism includes a moving mechanism and a lower end face camera. The moving mechanism is mounted on the frame, and the lower end face camera is connected to the output end of the moving mechanism. By adjusting the position of the lower end face camera through the moving mechanism, the distance between the lower end face camera and the reflective component is changed, further ensuring that the part is clearly imaged in the lower end face imaging mechanism.

[0014] Furthermore, the system also includes a position correction mechanism, which comprises a correction mounting frame, a first guide rod, a second guide rod, and a second fastener. The correction mounting frame is mounted on the frame. Both the first and second guide rods are rotatably connected to the correction mounting frame. The first and second guide rods are respectively fixed to the correction mounting frame by the second fastener. The distance from the first guide rod to the center of the transparent turntable mechanism is less than the distance from the second guide rod to the center of the transparent turntable mechanism. By setting the first and second guide rods, the position of the part is corrected to between the first and second guide rods, further facilitating clear imaging of the part by the subsequent visual inspection mechanism.

[0015] Furthermore, it also includes a positioning mechanism, which comprises a through-beam photoelectric sensor mounted on the frame. By setting up the positioning mechanism to locate the position of the parts, it facilitates the subsequent control of the vision inspection mechanism and the unloading and sorting mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The present invention provides an inspection and sorting machine. By setting a reflective component, the image of the part is reflected by the reflective component through the transparent turntable mechanism and then imaged onto the lower end face imaging mechanism. The lower end face imaging mechanism does not need to be set directly facing the transparent turntable mechanism, so that the overall length of the lower end face inspection mechanism is not limited by the space under the glass turntable, which makes it easy to disassemble and maintain the lower end face imaging mechanism, while improving the space utilization rate.

[0017] 2. The present invention provides a detection and sorting machine that adjusts the imaging angle of the reflecting prism by rotating the mounting box. After adjustment, the position of the mounting box is fixed by the first fastener to ensure that the parts are clearly imaged into the lower end face imaging mechanism.

[0018] 3. The present invention provides an inspection and sorting machine that adjusts the position of the lower end face camera by moving the mechanism, thereby changing the distance between the lower end face camera and the reflective component, ensuring that the parts are clearly imaged into the lower end face imaging mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. The present utility model will be further described below with reference to specific embodiments.

In order to better illustrate the embodiments of the present utility model, some parts in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. Furthermore, if the embodiments of this utility model involve descriptions such as "first" and "second," these descriptions are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features. In addition, the meaning of "and / or" in the whole text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B.

[0023] Example 1 This embodiment is a first embodiment of a detection and sorting machine, such as... Figure 1 As shown, the system includes a frame 100 and a transparent turntable mechanism 200, a vision inspection mechanism, and a material sorting mechanism 300, all mounted on the frame 100. In this embodiment, the frame 100 uses an aluminum alloy frame. The transparent turntable mechanism 200, the vision inspection mechanism, and the material sorting mechanism 300 are all located on the upper layer of the aluminum alloy frame, and an industrial control computer is located on the lower layer of the aluminum alloy frame. The vision inspection mechanism includes a lower end face inspection mechanism 400, a side face inspection mechanism 500, and an upper end face inspection mechanism 600, all mounted on the frame 100. The lower end face inspection mechanism 400 includes a lower end face imaging mechanism 410 and a reflective component 420, both mounted on the frame 100. The reflective component 420 is located below the transparent turntable mechanism 200, with its incident surface facing the transparent turntable mechanism 200 and its exit surface facing the lower end face imaging mechanism 410. The incident and exit surfaces have an offset angle.

[0024] Specifically, such as Figure 2 As shown, the transparent turntable mechanism 200 includes a servo motor, a planetary reduction rotary platform, a shaft system, and an optical glass turntable. The output end of the servo motor is connected to the optical glass turntable sequentially through the planetary reduction rotary platform and the shaft system. The servo motor is mounted on the frame 100, and the servo motor is specifically the MSMF022L1U2M model servo motor developed by Panasonic. Specifically, the reflective component 420 is located on the inner side below the optical glass turntable, and the lower end face imaging mechanism 410 is horizontally positioned on the outer side below the optical glass turntable. This eliminates the need for the lower end face imaging mechanism 410 to be placed vertically on the inner side below the optical glass turntable, thus freeing its overall length from the space below the glass turntable. This facilitates the disassembly and maintenance of the lower end face imaging mechanism 410 and improves space utilization.

[0025] like Figure 3 and Figure 4 As shown, the reflective assembly 420 includes a reflective mounting bracket 421, a mounting box 422, and a reflective prism 423. The reflective mounting bracket 421 is mounted on the frame 100, the mounting box 422 is mounted on the reflective mounting bracket 421, and the reflective prism 423 is located inside the mounting box 422. The mounting box 422 has an inlet and an outlet, with the inlet surface facing the inlet and the outlet surface facing the outlet. The reflective prism 423 is located inside the mounting box 422, which is mounted on the frame 100 via the reflective mounting bracket 421. The image of the part is reflected by the reflective prism 423 through the inlet to the outlet, and then imaged into the lower end face imaging mechanism 410.

[0026] The reflecting prism 423 is configured as a total internal reflection prism, and the inner diameters of its entrance and exit ports are not less than the outer diameter of the part to be inspected. This ensures that the part is clearly imaged in the lower end face imaging mechanism 410. In this embodiment, as... Figure 5 As shown, the total internal reflection prism is a right-angled triangular prism with a right-angled triangle cross-section. The two right-angled faces are the incident and exit faces, respectively, and the inclined plane is the reflecting plane. The two acute angles are 45°, causing the light path to deflect by 90°. Specifically, when light enters the prism perpendicularly through one of its right-angled faces, it undergoes a total internal reflection on the 45° inclined plane and then exits perpendicularly from the other right-angled face. This embodiment primarily targets gear detection; to ensure clear imaging of the gear, the width of the prism's incident face (40mm × 55mm) is greater than the gear's maximum outer diameter (31mm).

[0027] The reflective assembly 420 also includes a first fastener 424. The mounting box 422 is rotatably connected to the reflective mounting bracket 421, and the mounting box 422 can be fixed to the reflective mounting bracket 421 by the first fastener 424. The imaging angle of the reflective prism 423 can be adjusted by rotating the mounting box 422. After adjustment, the position of the mounting box 422 is fixed by the first fastener 424 to ensure that the part is clearly imaged into the lower end face imaging mechanism 410.

[0028] The reflective mounting bracket 421 includes a connecting bracket 421a, a first connecting plate 421b, and a second connecting plate 421c. The connecting bracket 421a is mounted on the frame 100. The first connecting plate 421b and the second connecting plate 421c are respectively located at both ends of the connecting bracket 421a. The first connecting plate 421b has a rotating groove. The mounting box 422 has a rotating rod 422a for rotating with the rotating groove. The first fastener 424 is a bolt. The second connecting plate 421c has a mounting hole, and the bolt is located in the mounting hole. The mounting box 422 has a threaded hole 422b for threaded connection with the bolt. When the mounting box 422 is rotated, the rotating rod 422a rotates in the rotating groove. After rotation, the first fastener 424 is threadedly connected to the threaded hole 422b, thus fixing the mounting box 422.

[0029] The first connecting plate 421b is equipped with a pointer 421d, and the mounting box 422 is equipped with an angle scale 422c. When the mounting box 422 is rotated, the pointer 421d points to different angle scales 422c, thus allowing for a clear and intuitive observation of the adjusted angle.

[0030] The lower end face inspection mechanism 400 also includes a semi-annular light source 430, which is mounted on the frame 100 and located between the reflective component 420 and the transparent turntable mechanism 200. By setting the semi-annular light source 430, the light source is made to fit the imaging path more closely, further ensuring that the part is clearly imaged in the lower end face imaging mechanism 410.

[0031] like Figure 2 As shown, in this embodiment, the side detection mechanism 500 adopts a detection layout in which three FA lenses are evenly distributed in a ring. With the gear central axis as the axis of symmetry, the angle between adjacent lenses is 120°. During the detection process, the platform drives the gear to rotate at a constant speed and reach the designated position. The three lenses instantaneously and synchronously acquire images, respectively capturing tooth surface information at different angles of the gear, and perform image fusion and discrimination.

[0032] The upper surface inspection mechanism 600 adopts the most common shooting layout in industrial sites, with the lens completely perpendicular to the upper surface of the gear to directly collect image information.

[0033] In the vision inspection mechanism, the industrial camera and light source are fixed on a high-precision adjustable vertical lifting gear rack dovetail slide, with a scale accuracy of 1mm. Meanwhile, the adjustment range can be extended to 250mm. The ring light source and semi-ring light source are respectively fixed to the inspection station via light source brackets and can be adjusted according to their respective needs.

[0034] The working principle of a detection and sorting machine in this embodiment is as follows: When inspecting a part, the part is placed on a transparent turntable mechanism 200. The turntable mechanism 200 is activated, and the part is conveyed to a vision inspection mechanism. The lower end face inspection mechanism 400 performs visual inspection on the lower end face of the part, the side face inspection mechanism 500 performs visual inspection on the side face of the part, and the upper end face inspection mechanism 600 performs visual inspection on the upper end face of the part. After the visual inspection is completed, the transparent turntable mechanism 200 sends the part to a material unloading and sorting mechanism 300, which sorts and unloads the part according to the inspection results. During the visual inspection of the lower end face of the part, the image of the part is reflected by the reflective component 420 through the transparent turntable mechanism 200 and then imaged into the lower end face imaging mechanism 410. By setting the reflective component 420, the image of the part is reflected by the reflective component 420 through the transparent turntable mechanism 200 and then imaged into the lower end face imaging mechanism 410. The lower end face imaging mechanism 410 does not need to be set directly facing the transparent turntable mechanism 200, so that the overall length of the lower end face detection mechanism is not limited by the space under the glass turntable, which makes it easy to disassemble and maintain the lower end face imaging mechanism 410, while improving space utilization.

[0035] Example 2 This embodiment is the second embodiment of the detection and sorting machine. This embodiment is similar to the first embodiment, except that, as Figure 3 and Figure 4As shown, the lower end face imaging mechanism 410 includes a moving mechanism 411 and a lower end face camera 412. The moving mechanism 411 is mounted on the frame 100, and the lower end face camera 412 is connected to the output end of the moving mechanism 411. Specifically, the moving mechanism 411 uses an existing adjustable horizontal gear rack dovetail slide, and the lower end face camera 412 can be driven by the adjustable horizontal gear rack dovetail slide to move radially along the optical glass turntable.

[0036] The position of the lower end face camera 412 is adjusted by the moving mechanism 411, thereby changing the distance between the lower end face camera 412 and the reflective component 420, further ensuring that the part is clearly imaged into the lower end face imaging mechanism 410.

[0037] Example 3 This embodiment is the third embodiment of the detection and sorting machine. This embodiment is similar to Embodiment 1, except that, as Figure 6 As shown, the system also includes a position correction mechanism 700. The position correction mechanism 700 includes a correction mounting frame 710, a first guide rod 720, a second guide rod 730, and a second fastener 740. The correction mounting frame 710 is mounted on the frame 100. Both the first guide rod 720 and the second guide rod 730 are rotatably connected to the correction mounting frame 710. The first guide rod 720 and the second guide rod 730 are respectively fixed to the correction mounting frame 710 via the second fastener 740. The distance from the first guide rod 720 to the center of the transparent turntable mechanism 200 is less than the distance from the second guide rod 730 to the center of the transparent turntable mechanism 200. Specifically, the first guide rod 720 pushes the loaded parts outwards, while the second guide rod 730 prevents the parts from detaching from the optical glass turntable by applying inward force. By setting the first guide rod 720 and the second guide rod 730, the position of the part is corrected to be between the first guide rod 720 and the second guide rod 730, ensuring that the part is accurately guided within the preset radius range of the visual inspection disk, which further facilitates the subsequent visual inspection mechanism to clearly image the part.

[0038] Specifically, the calibration mounting bracket 710 includes an adjustable vertical lifting gear rack dovetail groove slide and a connecting plate. The connecting plate is connected to the output end of the adjustable vertical lifting gear rack dovetail groove slide. The first guide rod 720 and the second guide rod 730 are both rotatably connected to the connecting plate. The first guide rod 720 and the second guide rod 730 are respectively fixed to the connecting plate by the second fastener 740.

[0039] Example 4 This embodiment is the fourth embodiment of the detection and sorting machine. This embodiment is similar to embodiment three, except that, as Figure 7As shown, the system also includes a positioning mechanism 800, which comprises a through-beam photoelectric sensor mounted on the frame 100. Specifically, the through-beam photoelectric sensor includes a transmitter and a receiver, located on opposite sides of the first guide rod 720 and the second guide rod 730, respectively. A servo motor is connected to an absolute encoder. During this positioning process, the encoder continuously collects and records position data. When a part passes through the detection area of ​​the photoelectric sensor, the industrial control computer can capture and process the corresponding pulse signal in real time. Based on this signal, the industrial control computer can determine the real-time position of the part under test and calculate how far it needs to travel to trigger the vision inspection mechanism and the unloading and sorting mechanism 300. By setting the positioning mechanism 800 to locate the part, it facilitates the subsequent control of the vision inspection mechanism and the unloading and sorting mechanism 300.

[0040] Specifically, the material sorting mechanism 300 includes three sets of solenoid valves, cylinders, and sorting boxes. The three sorting boxes correspond to qualified products, unqualified products, and products awaiting re-inspection, respectively. The solenoid valves precisely control the airflow, thereby driving the cylinders to perform extension and retraction actions. Specifically, the solenoid valves are 4V210-08 type solenoid valves, and the cylinders are TN16×75-S model short-stroke double-rod cylinders manufactured by Airtac.

[0041] When the test result is unqualified, the control system activates the corresponding solenoid valve, drives the corresponding cylinder to extend, and pushes the part into the unqualified product sorting box; when the test result is qualified, the control system activates the corresponding solenoid valve, drives the corresponding cylinder to extend, and pushes the part into the qualified product sorting box; for gears that have not completed the test or have abnormal test results, the system activates the third set of solenoid valves by default, drives the corresponding cylinder to move, and pushes the uninspected product into the product sorting box to be re-inspected.

[0042] To prevent the cylinder push rod tip from making hard contact with parts during reciprocating sorting, thus avoiding damage and collisions, the cylinder push rod tip is made of rubber. This significantly reduces the maximum contact stress on the surface of the parts during sorting, effectively preventing damage.

[0043] In this embodiment, a feeding mechanism 900 is also included. The feeding mechanism 900 uses an existing vibratory feeder. The parts to be tested are stacked in the vibratory feeder and automatically fed by the vibratory feeder.

[0044] In this embodiment, after the part to be inspected is automatically fed to the transparent turntable mechanism 200 by the vibratory feeder, its loading position is first corrected by the position correction mechanism 700 to ensure that it is in the preset detection reference position. Then, the positioning mechanism 800 positions the part, providing precise timing triggering conditions for the subsequent visual inspection mechanism and unloading and sorting mechanism 300. When the part rotates sequentially to the lower end face inspection mechanism 400, the side inspection mechanism 500, and the upper end face inspection mechanism 600, the lower end face inspection mechanism 400, the side inspection mechanism 500, and the upper end face inspection mechanism 600 automatically perform visual recognition on the part, and the industrial control computer processes the results. Finally, the part arrives at the workstation of the unloading and sorting mechanism 300, which sorts and guides the part to the corresponding unloading channel according to the recognition results, thereby realizing efficient, non-destructive inspection and automated sorting of large batches of gears in industrial scenarios.
