Description

Technical Field

[0001] This invention relates to the field of fully automated bearing surface inspection devices, and more specifically to a fully automated bearing surface inspection line. Background Technology

[0002] Existing fully automated bearing surface inspection lines employ multiple inspection mechanisms (see...) Figure 1 These cameras are used to inspect the upper, lower, inner, and outer ring circumferential areas of the bearing. The inspection mechanism for the outer ring circumferential area requires multiple first and second camera components to observe the upper and lower parts of the outer ring circumferential area. The working surfaces of the first and second camera components are arranged at an angle and combined in a V-shape to facilitate observation of the bearing's outer ring circumferential area. The light source is generally located at the top, and the bottom edge area of ​​the bearing often suffers from insufficient light due to obstruction, resulting in a significant color difference between the image and the well-lit top area of ​​the bearing. Furthermore, because the bearing is placed on the assembly line support plate, the bottom of the first and second camera components can only be flush with the top edge of the assembly line support plate at most. However, the second camera component located at the bottom still has difficulty capturing images of the bottom edge area of ​​the bearing due to interference from the assembly line support plate, increasing the inspection difficulty. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a fully automated bearing surface inspection line. This solves the shortcomings of existing fully automated bearing surface inspection lines, where the light source is typically located at the top, resulting in insufficient light in the bearing's bottom edge area due to obstruction. Furthermore, the images from these obstructed areas often exhibit significant color differences compared to the well-lit top area of ​​the bearing. Additionally, because the bearing is placed on the production line support plate, the second camera component at the bottom is difficult to image the bearing's bottom edge area due to interference from the support plate, further increasing the inspection difficulty.

[0004] The technical solution adopted in this invention is as follows:

[0005] An automated bearing surface inspection line includes: an inspection line frame, on which a first inspection mechanism, a flipping mechanism, a second inspection mechanism, a third inspection mechanism, and a fourth inspection mechanism are sequentially arranged; the fourth inspection mechanism is used to inspect the outer circumferential surface area of ​​the bearing; the fourth inspection mechanism includes a first camera assembly and a second camera assembly, the working surfaces of the first camera assembly and the second camera assembly are both arranged at an inclination and combined in a V shape, a mounting groove is provided on the production line support plate facing the fourth inspection mechanism, a lifting assembly for lifting the bearing is provided in the mounting groove, a detachable rectangular cover is installed on the outside of the mounting groove, light sources are provided at the bottom of the left and right side walls of the cover, a reflective surface for reflecting the light from the light sources is provided on the upper part of the left and right side walls of the cover, and an entrance is provided on the rear end face of the cover to facilitate the passage of the first camera assembly and the second camera assembly. This invention utilizes a housing to illuminate the bottom edge area of ​​the bearing with a light source. Reflective surfaces on the upper left and right side walls of the housing reflect the light from the bottom source back to the upper part of the housing, thus fully illuminating the top edge area of ​​the bearing. This, combined with lifting the bearing, allows for better observation of the second camera assembly, which is flush with the production line. This invention solves the problems of existing fully automated bearing surface inspection lines where the light source is typically located at the top, resulting in insufficient light at the bottom edge of the bearing due to obstruction, and a significant color difference between the image and the well-lit top area. Furthermore, because the bearing is placed on the production line support plate, the second camera assembly at the bottom has difficulty capturing images of the bottom edge area. This invention reduces the difficulty of inspection.

[0006] Optionally, the first detection mechanism, the flipping mechanism, the second detection mechanism, the third detection mechanism, and the fourth detection mechanism are provided with a production line support plate on their front sides; the production line support plate is provided with a baffle on the side of the production line support plate near the first detection mechanism.

[0007] Optionally, the lifting assembly includes a base plate, on which a lifting drive is mounted. The output shaft of the lifting drive is connected to an L-shaped plate. A movable plate is mounted on the outer wall of the L-shaped plate. A through hole is provided in the center of the movable plate. An intermediate plate is provided below the movable plate. A rotating motor is mounted on the intermediate plate. A support column is connected to the end of the output shaft of the rotating motor. The support column moves up and down to insert into the through hole. When not in use, the movable plate is flush with the assembly line support plate.

[0008] Optionally, a first hydraulic lifting column is installed on the base plate, the top of the first hydraulic lifting column is connected to the middle plate, and a second hydraulic lifting column is also installed on one side of the base plate. The top of the first hydraulic lifting column is connected to the bottom of the movable plate, and the bottoms of the first hydraulic lifting column and the second hydraulic lifting column are connected to each other.

[0009] Optionally, the bottom of the cover is connected to a connecting column, and the end of the connecting column away from the cover is connected to a movable column. A connecting piece is fitted on the bottom of the movable column, and a support block is installed on the upper part of the end of the connecting piece away from the movable column. A lower abutment column is installed at the lower part of the end of the connecting piece, and a micro-control switch is provided at the bottom of the lower abutment column. A trigger column is installed on the middle plate. The trigger column moves upward to abut the micro-control switch. When the micro-control switch is triggered, the light source is automatically turned on.

[0010] Optionally, the bottom of the left and right side walls of the enclosure is provided with a fixing plate, the upper surface of the fixing plate is inclined upward, and the light source is installed on the upper surface of the fixing plate so that the light shines obliquely upward.

[0011] Optionally, the left and right side walls of the cover are made of one-way transparent glass, with the reflective surface located on the inside. The middle of the inner surface of the left and right side walls of the cover is recessed inward to form a reflective surface.

[0012] Optionally, the light source may employ multiple sets of LED beads.

[0013] Optionally, the reflective surface is provided with diffuse reflection strips.

[0014] Optionally, the top wall of the enclosure is made of one-way transparent glass, with its reflective surface located on the inside.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. This invention, by setting up a cover, uses a light source to illuminate the bottom edge area of ​​the bearing. Reflective surfaces on the upper left and right side walls of the cover reflect the light from the bottom light source to the upper part of the cover, thus fully illuminating the top edge area of ​​the bearing. This, combined with lifting the bearing, allows for better observation of the second camera assembly installed flush with the production line. This invention reduces the difficulty of inspection.

[0017] 2. The present invention solves the problem that the light source of the existing fully automatic bearing surface detection line is generally located at the top, and the bottom edge area of ​​the bearing is often insufficiently lit due to obstruction. Moreover, there is a significant color difference between the image of the bearing and the well-lit top area. At the same time, since the bearing is placed on the production line support plate, the second camera component located at the bottom has difficulty capturing the bottom edge area of ​​the bearing due to the obstruction of the production line support plate.

[0018] 3. In this invention, the bottoms of the first and second hydraulic lifting columns are interconnected, ensuring that the hydraulic oil pressure in both columns is the same. When the movable plate moves downwards, it compresses the second lifting column, causing the first lifting column to extend and lift the intermediate plate. The descent of the movable plate and the rise of the intermediate plate are synchronized, resulting in a shorter stroke for the movable plate and a smaller overall lifting assembly size. When not in use, the movable plate is flush with the production line support plate, also serving to guide the bearing movement. This eliminates the need for a separate bearing lifting mechanism, simplifying the overall structure. During this process, the movable plate itself does not interfere with the detection of the second detection component.

[0019] 4. The operator of this invention can see the internal testing process through the left and right side walls and the top wall of the cover. Even if the bearing slips out, the fault can be directly observed, which makes it convenient for the operator to troubleshoot. At the same time, the inner side of the left and right side walls of the one-way transparent glass cover is recessed inward to form a reflective surface, which does not require the setting of an additional reflective surface, and the structure is ingenious.

[0020] 5. The diffuse reflection strip of this invention has an isosceles right-angled triangle cross-section, allowing it to reflect light from the top or bottom, making it clearly observable. The image captured by the first camera component from the reflective surface will have a red line, facilitating the identification and elimination of this marking line from the final image analysis based on its shape, color, or position information. This simplifies the process of excluding these interfering image parts from the analysis. Furthermore, the height of the diffuse reflection strip is much higher than the outer surface of the bearing, making the light reflected by the diffuse reflection strip less likely to be reflected by the bearing surface and observed by the first camera component.

[0034] Example 1

[0035] The technical solution adopted in this invention is as follows:

[0036] like Figure 2 As shown, this invention discloses a fully automated bearing surface inspection line, comprising: an inspection line frame, on which a feeding mechanism 100, a first inspection mechanism 200, a flipping mechanism 300, a second inspection mechanism 400, a third inspection mechanism 500, a fourth inspection mechanism 600, and a sorting mechanism 700 are sequentially arranged; the first inspection mechanism is used to inspect the upper end face of the bearing, the second inspection mechanism is used to inspect the lower end face of the bearing, the third inspection mechanism is used to inspect the inner circumferential surface area of ​​the bearing, and the fourth inspection mechanism is used to inspect the outer circumferential surface area of ​​the bearing; a production line support plate 1 is provided in front of the first inspection mechanism, the flipping mechanism, the second inspection mechanism, the third inspection mechanism, and the fourth inspection mechanism. A baffle 2 is provided on the side of the production line support plate near the first inspection mechanism.

[0037] In this embodiment, the feeding mechanism, the first detection mechanism, the flipping mechanism, the second detection mechanism, the third detection mechanism, the fourth detection mechanism, and the sorting mechanism are all connected to an external control system.

[0038] like Figure 3 As shown, the fourth detection mechanism includes a first camera component 3 and a second camera component 4. The working surfaces of the first camera component and the second camera component are both arranged at an inclination and combined into a V shape. A mounting groove 5 is provided on the assembly line support plate facing the fourth detection mechanism. A detachable rectangular cover 6 is installed on the outside of the mounting groove. Light sources 7 are provided on the bottom of the left and right side walls of the cover. In this embodiment, the light source adopts multiple sets of lamp beads.

[0039] like Figure 5 As shown, the upper part of the left and right side walls of the cover is provided with reflective surfaces 8 for reflecting light from the light source, and the rear end face of the cover is provided with an entrance for the first camera assembly and the second camera assembly to pass through.

[0040] like Figure 3 As shown, the mounting slot is provided with a lifting assembly for lifting the bearing, the lifting assembly 9, the lifting assembly includes a base plate 10, the base plate is equipped with a lifting drive component 11, the output shaft of the lifting drive component is connected to an L-shaped plate 12, the outer wall of the L-shaped plate is equipped with a movable plate 13, the movable plate has a through hole 14 in the center, the movable plate is provided with an intermediate plate 15 below the movable plate, the intermediate plate is equipped with a rotating motor 16, the output shaft of the rotating motor is connected to a support column 17, the support column moves up and down to insert into the through hole.

[0041] In this embodiment, the movable plate is flush with the production line support plate when not in use, and also serves to guide the movement of the bearing.

[0042] The base plate is equipped with a first hydraulic lifting column 19, the top of which is connected to an intermediate plate. A second hydraulic lifting column 18 is also installed on one side of the base plate. The top of the first hydraulic lifting column is connected to the bottom of the movable plate. The bottoms of the first and second hydraulic lifting columns are connected to each other through a connecting pipe 32.

[0043] The bottom of the cover is connected to a connecting post 20. The end of the connecting post away from the cover is connected to a movable post 21. A connecting piece 22 is fitted on the bottom of the movable post. A support block 23 is installed on the upper part of the end of the connecting piece away from the movable post. A lower abutment post 24 is installed at the lower end of the connecting piece. A micro-control switch is provided at the bottom of the lower abutment post. A trigger post 25 is installed on the middle plate. The trigger post moves upward to abut the micro-control switch. When the micro-control switch is triggered, the light source is automatically turned on.

[0044] In this embodiment, the control system coordinates the operation of the rotating motor via a microswitch. The signal triggered by the microswitch is transmitted to the control system, which then activates the rotating motor. Finally, it controls the first and second camera components of the fourth detection mechanism to operate.

[0045] The bottom of the left and right side walls of the enclosure are provided with fixing plates 26. The upper surface of the fixing plates is inclined upwards, and the light source is installed on the upper surface of the fixing plates so that the light shines obliquely upwards. A reflector is installed on the top wall of the enclosure.

[0046] In this embodiment, as Figure 4 As shown, a first limiting baffle 27 is provided at the front end of the bottom of the cover. A second limiting baffle 28 is provided at the rear end of the cover, and a slot 29 is provided at the bottom of the second limiting baffle, into which the baffle is inserted.

[0047] In this embodiment, the first and second hydraulic lifting columns are filled with hydraulic oil. The bottoms of the first and second hydraulic lifting columns are connected to each other, so that the hydraulic oil pressure in the first and second hydraulic lifting columns is the same, and when the movable plate moves downward, it drives the second hydraulic lifting column to be compressed, causing the first hydraulic lifting column to extend and lift the intermediate plate.

[0048] In this embodiment, the support block is provided with a permanent magnet, and the movable plate is made of iron.

[0049] In this embodiment, the hydraulic oil pressure in the first and second hydraulic lifting columns is the same, so that when the movable plate moves downward, the second hydraulic lifting column is compressed, causing the first hydraulic lifting column to extend and lift the middle plate. The trigger column on the middle plate moves upward to abut the micro-control switch. When the micro-control switch is abutted, the light source is turned on, and the rotating motor is started at the same time, driving the bearing to rotate. The fourth detection mechanism begins detection.

[0050] Example 2

[0051] The difference between Embodiment 2 and Embodiment 1 is that the left and right side walls of the cover are made of one-way transparent glass, with the reflective surface located on the inner side. The inner surface of the left and right side walls of the cover is recessed inward to form a reflective surface. The top wall of the cover is made of one-way transparent glass, with the reflective surface located on the inner side.

[0052] In this embodiment, the operator can see the internal testing process through the left and right side walls and the top wall of the enclosure. Even if the bearing slips out, the fault can be directly observed, facilitating troubleshooting. Simultaneously, the inner center of the left and right side walls of the one-way transparent glass enclosure is recessed to form a reflective surface, eliminating the need for an additional reflective surface, resulting in a clever structure. The image generated by the reflective surface itself is distorted, making it easy to distinguish even if the first camera component captures an image generated by the reflective surface. The first camera component observes geometric distortions (such as perspective distortion and lens distortion) to analyze whether structures that should be straight in the image are bent, thereby eliminating distorted images.

[0053] Example 3

[0054] The difference between Example 3 and Example 2 is that, as Figure 6 and Figure 7 As shown, the reflective surface is provided with diffuse reflection strips 30. The width of the reflection strips is 0.1-0.5cm.

[0055] In this embodiment, the diffuse reflection strip has an isosceles right triangle cross section with its vertex located at the top of the reflective surface, and a red diffuse reflection sheet 33 is provided on one side of the right-angled side of the diffuse reflection strip.

[0056] In another embodiment, the height of the cover can be increased as needed.

[0057] In this embodiment, the diffuse reflection strip has an isosceles right-angled triangle cross-section, allowing it to reflect light from the top or bottom, making it clearly observable. The image captured by the first camera component from the reflective surface will have red lines, facilitating the algorithm's elimination of interfering image parts from the image captured by the first camera component itself, simplifying the process of removing these interfering image parts from the analysis. Furthermore, the height of the diffuse reflection strip is much higher than the outer surface of the bearing, making it less likely for the light reflected by the bearing surface to be observed by the first camera component.

[0058] Example 4

[0059] The difference between Example 4 and Example 1 is that, as Figure 8 As shown, the top of the left and right side walls of the enclosure is provided with a top plate 31, and a light source is provided on the top plate. In this embodiment, the light source on the top plate is used to supplement the light.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
