Description

Technical Field

[0001] This invention relates to the field of glass cover inspection technology, specifically a rotating inspection device. Background Technology

[0002] As a core exterior and protective component of electronic devices, the quality of glass covers directly determines the user experience and market competitiveness of end products. Whether it's the scratch and wear resistance requirements of mobile phone screens, the high and low temperature resistance and light transmittance requirements of automotive central control screens, or the flatness and optical consistency standards of curved displays, stringent requirements are placed on the defect control of glass covers.

[0003] Currently, defect detection requires multi-angle flipping inspection. To ensure stability during flipping, suction cups are used for adsorption and fixation. The industry commonly uses a vacuum suction cup with a support arm for fixation: the suction cup adsorbs the glass surface through negative pressure, while the support arm supports it from below and drives the glass to complete the flipping action. This flipping method has high stability, but the suction cup and support arm need to exert force from below the glass, and their contact area is usually the lower edge. This area directly blocks the sampling field of view of the machine vision system. For large-sized glass, the support arm needs a multi-support structure to ensure adsorption stability, resulting in a larger obstruction area. This creates more blind spots in the inspection, requiring secondary manual inspection and offsetting the efficiency advantage of machine vision. Summary of the Invention

The flipping component drives the glass plate to rotate around the horizontal axis, and it has a first position, a second position and a third position in its rotation stroke.

[0007] The shooting component and the flipping component are connected by a linkage component.

At the first position, the second position and the third position, the shooting component shoots the edge area, the middle area and the other edge area of ​​the glass plate, respectively.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-9 The present invention provides a rotating inspection device, including a flipping component 2, a linkage component 8, and further comprising:

[0032] The floating component 4 and the glass plate 6 are fixed to the flipping component 2 by the vacuum adsorption of the floating component 4. The flipping component 2 drives the glass plate 6 to rotate around the horizontal axis, and it has a first position, a second position and a third position in its rotation stroke.

[0033] The shooting component 9 and the flipping component 2 are connected by a linkage component 8. During the rotation of the glass plate 6, the shooting component 9 is linearly displaced along the length of the glass plate 6. At the first position, the second position and the third position, the shooting component 9 shoots the edge area, the middle area and the other edge area of ​​the glass plate 6 respectively.

[0034] When the shooting component 9 moves to the corresponding shooting area, the floating component 4 corresponding to that area is passively detached from the glass plate by releasing negative pressure.

[0035] In the first state, the tilting frame 21 is in a horizontal initial position, and the glass plate 6 is moved above the tilting frame 21 by a robotic arm or manually, as shown in the attached diagram. Figure 5 and 6 As shown, at this time, in the floating component 4, the first suction cup 422 is perpendicular to the glass plate 6, while the second suction cup 472 is parallel to the glass plate 6. The glass plate 6 is placed on the second suction cup 472. The negative pressure pump performs low-pressure adsorption on the second suction cup 472 through the solenoid valve group so that the glass plate 6 is firmly fixed. At this time, the imaging component 9 is used to acquire images of the edge area of ​​the glass plate 6.

[0036] Then, by rotating component 2 by 30 degrees, glass plate 6 is rotated to the second position. Simultaneously, the shooting component 9 moves to the position as shown in the attached image under the linkage of component 8. Figure 3 At the position shown, the imaging component 9 corresponds to the central area of ​​the glass plate 6. The imaging component 9 captures images of the central area. During this process, the linkage component 8 drives the floating component 4 to switch states. Figure 7 Current status, switch to attached Figure 8 In this state, the first suction cup 422 rotates 90 degrees and adheres to the glass plate 6. Simultaneously, the solenoid valve opens, allowing the first suction cup 422 to adhere to the glass plate 6, while the second suction cup 472 releases pressure. Thus, the second suction cup 472 detaches from the glass plate 6 and rotates 90 degrees clockwise to form the shape shown in the attached image. Figure 9 As shown, this prevents the second suction cup 472 from obstructing the shooting screen when the shooting component 9 is shooting the central area;

[0037] After the shooting is completed, the glass plate 6 is moved to the third position by rotating the flip component 2 by 30 degrees to shoot another edge area. Similarly, the floating component 4 between the second and third positions is switched to switch the first suction cup 422 and the second suction cup 472 so that the shooting component 9 can shoot the corresponding area without obstruction, ensuring the clarity of the shooting and improving the recognition accuracy.

[0038] In the embodiments of the present invention, please refer to Figure 3 The flipping assembly 2 includes a frame 1, a flipping frame 21, and a servo motor 22. The flipping frame 21 is rotatably connected to the frame 1, and the servo motor 22 is used to drive the flipping frame 21 to rotate.

[0039] During operation, in the first position, the tilting frame 21 is in a horizontal state. The servo motor 22 receives the signal from the PLC and drives the tilting frame 21 to rotate counterclockwise by 30 degrees to the second position, and then continues to rotate by 30 degrees to switch to the third position.

[0040] For embodiments of the present invention, please refer to [link / reference]. Figure 2 , 7 As shown in Figure 9, the floating assembly 4 includes multi-stage shafts 3, rotating sleeves 41, track grooves 411, a first protective sleeve 42, a first swing arm 421, a first suction cup 422, a reversing part, a connecting sleeve 46, a second protective sleeve 47, a second swing arm 471, and a second suction cup 472. The multi-stage shafts 3 include a first rotating shaft 31 and a second rotating shaft 32. The first rotating shaft 31 is fixedly mounted on the flipping assembly 2, and the second rotating shaft 32 is rotatably connected to the outside of the first rotating shaft 31. A pair of rotating sleeves 41, the first protective sleeve 42, and the connecting sleeve 46 are rotatably sleeved on the first rotating shaft 31. The track groove 41... A first swing arm 421 is fixedly mounted on a first protective sleeve 42, and a first suction cup 422 is fixedly mounted on the first swing arm 421. A pair of second protective sleeves 47 are fixedly mounted on the outside of a second rotating shaft 32. A second swing arm 471 is fixedly mounted on a second protective sleeve 47, and a second suction cup 472 is fixedly mounted on a second swing arm 471. The first protective sleeve 42 and the connecting sleeve 46 are connected by a reverse transmission part, so that the first protective sleeve 42 and the connecting sleeve 46 rotate in opposite directions, realizing that the first suction cup 422 and the second suction cup 472 are alternately adsorbed on the glass plate 6. An inner embedded block 461 is fixedly mounted on the connecting sleeve 46, and a sliding block 464 is fixedly mounted on the second protective sleeve 47. An annular rail 462 is fixedly mounted on the sliding block 464. The inner embedded block 461 and the annular rail 462 are slidably connected, and an elastic element 463 is sleeved on the annular rail 462.

[0041] When the linkage component 8 drives the shooting component 9 to move from the first position to the second position, the guide post 85 set on the linkage component 8 will insert into the track groove 411 opened on the rotating sleeve 41. As the guide post 85 moves, it applies a rotational force to the rotating sleeve 41. The rotating sleeve 41, the first protective sleeve 42, the first swing arm 421, and the first suction cup 422 rotate 90 degrees counterclockwise in sync. During the rotation, under the transmission action of the reverse part, the connecting sleeve 46 will rotate clockwise. The embedded block 461 will rotate with the connecting sleeve 46, thereby compressing the elastic element 463 until the first suction cup 422 contacts the glass plate 6 and performs adsorption. After adsorption is completed, the second suction cup 472 releases the glass plate 6, and the elastic element 463 is in a compressed state. It applies a pushing force to the sliding block 464, causing it to rotate clockwise. The sliding block 464 and the second protective sleeve 47 are fixedly connected. Simultaneously, the second protective sleeve 47 will rotate 90 degrees clockwise to the attached position. Figure 9 As shown, this structure enables delayed reverse rotation between the first sheath 42 and the second sheath 47, ensuring that the two suction cups are always alternately covering the glass plate 6, thus preventing simultaneous detachment and displacement of the glass plate 6.

[0042] In the embodiments of the present invention, please refer to Figure 2 The reverse part includes a first face gear 43, a transmission gear 44, and a second face gear 45. The first face gear 43 is fixedly mounted on the first protective sleeve 42, and the second face gear 45 is fixedly mounted on the connecting sleeve 46. The first face gear 43 and the second face gear 45 are connected by transmission gear 44.

[0043] When the first sheath 42 drives the first face gear 43 to rotate counterclockwise, its teeth mesh with the teeth of the transmission gear 44, forcing the transmission gear 44 to rotate counterclockwise around its own axis. At the same time, the transmission gear 44 meshes with the second face gear 45. The counterclockwise rotating transmission gear 44 will drive the second face gear 45 to rotate clockwise. Since the second face gear 45 is fixed to the connecting sleeve 46, the connecting sleeve 46 eventually rotates clockwise synchronously, forming a counterclockwise synchronous rotation with the counterclockwise rotation of the first sheath 42.

[0044] In the embodiments of this invention, please refer to Figure 3 The linkage component 8 includes an arc-shaped rack 81, a lead screw 82, a driven gear 83, a displacement block 84, and a guide post 85. The arc-shaped rack 81 is fixedly mounted on the frame 1. The lead screw 82 is rotatably connected to the tilting frame 21. The driven gear 83 is fixedly mounted on the lead screw 82 and meshes with the arc-shaped rack 81. The displacement block 84 is threadedly connected to the lead screw 82. One end of the guide post 85 is fixedly mounted on the displacement block 84, and the other end of the guide post 85 extends to the floating component 4.

[0045] The arc-shaped rack 81 is rigidly fixed to the inner side of the frame 1 with bolts. Its curvature is concentric with the rotation trajectory of the tilting frame 21 to ensure meshing stability. The lead screw 82 is rotatably connected to the tilting frame 21 at both ends, ensuring that the axis of the lead screw 82 is parallel to the rotation plane of the tilting frame 21. The driven gear 83 is fixed to the input end of the lead screw 82, maintaining a 2mm meshing depth with the arc-shaped rack 81, and the transmission ratio is constant. When the servo motor 22 drives the tilting frame 21 to rotate around its own rotation axis:

[0046] The flip frame 21 drives the lead screw 82 and the driven gear 83 to move synchronously around the flip axis. At this time, the driven gear 83 and the fixed arc rack 81 roll relative to each other. The tooth surface of the rack pushes the driven gear 83 to rotate. The rotation of the driven gear 83 drives the lead screw 82 to rotate synchronously. Through the threaded engagement between the lead screw 82 and the displacement block 84, the rotational motion is converted into the linear displacement of the displacement block 84 along the axis of the lead screw 82. In this way, while realizing the change of the included angle between the glass plate 6 and the multispectral adjustable light source module 7, the passive drive drives the shooting component 9 fixed on the displacement block 84 to move.

[0047] In the embodiments of the present invention, please refer to Figure 3 and 5The shooting component 9 includes a stand 91, a guide rail 92, and a shooting device 93. The stand 91 is mounted on the linkage component 8, the guide rail 92 is mounted on the stand 91, and the shooting device 93 is detachably mounted on the guide rail 92.

[0048] The top of the displacement block 84 is rigidly connected to the stand 91 of the shooting component 9 by bolts. When the displacement block 84 moves along the lead screw 82, it can drive the shooting component 9 to move synchronously along the length of the glass plate 6. Its displacement is linearly related to the rotation angle of the flip frame 21. In the first position, the displacement block 84 and the shooting component 9 are located in the left edge area of ​​the glass plate 6. When rotated to the second position, the displacement block 84 moves to the middle area. When rotated to the third position, the displacement block 84 moves to the right edge area. In this way, the flip angle, displacement and shooting area are precisely matched.

[0049] In another embodiment of the present invention, a multispectral adjustable light source module 7 is further included, which is disposed above the glass plate 6. The multispectral adjustable light source module 7 has a built-in standard light source with two modes: natural light and ultraviolet light. The natural light mode is used to detect scratches and stains on the surface of the glass plate 6, and the ultraviolet light mode is used to detect fluorescent defects inside the glass plate 6.

[0050] During the left-to-right movement, the system remains in natural light mode. While the imaging component 9 takes photos, the system can also check the reflectivity of the glass plate 6 at different angles based on the brightness of the photos. During the reset phase, the system moves from right to left and enters ultraviolet light mode. Through a 365nm wavelength ultraviolet LED light group, the light penetrates the glass plate 6 and excites the internal fluorescent defects to emit fluorescence of a specific wavelength. The imaging component 9 is equipped with an ultraviolet filter that only receives the fluorescence signal emitted by the defects, thus clearly presenting the defect outline against a dark background and identifying internal fluorescent defects. The multispectral adjustable light source module 7 and the imaging component 9 are linked by a PLC. When the imaging component 9 moves to the target area and is ready to take a picture, the system automatically switches the light source mode according to the preset detection scheme.

[0051] In another embodiment of the present invention, a display and image processing module is further included, which is signal-connected to the shooting component 9 and is used to display the images captured by the shooting component 9. The display and image processing module has a built-in defect recognition algorithm, which can automatically mark suspected defect areas in the image and label the defect type, and also supports image magnification and comparison analysis functions.

[0052] The module consists of an industrial display, an embedded processor, and a data storage unit. It establishes a signal connection with the shooting device 93 of the shooting component 9 through a wireless communication module, and can receive captured images in real time. Through the settings of the display module, items that are difficult for the machine vision system to distinguish, such as water stains on the glass surface and real scratches, can be judged by human assistance to improve the accuracy of defect identification.

[0053] In another embodiment of the present invention, it includes a negative pressure pump and a solenoid valve assembly. The negative pressure pump is connected to a first suction cup 422 and a second suction cup 472 via air pipes. The solenoid valve assembly is used to switch the negative pressure on and off of the two suction cups. The negative pressure module is linked to the imaging component 9. When the imaging component 9 moves to the corresponding imaging area, the negative pressure module controls the suction cup corresponding to that area to cut off the negative pressure and open the suction cups in other areas to adsorb. The pressure control system is linked to the displacement signal of the imaging component 9. When the displacement block 84 moves the imaging component 9 to the corresponding area:

[0054] When the shooting component 9 is in the left edge area, the solenoid valve group cuts off the negative pressure of the first suction cup 422 while maintaining the negative pressure of the second suction cup 472, ensuring that the middle part of the glass plate 6 is attracted and fixed. When the shooting component 9 moves to the middle area (second position), the solenoid valve group cuts off the negative pressure of the second suction cup 472 while maintaining the negative pressure of the first suction cup 422 to prevent the middle area from being blocked. When the shooting component 9 moves to the right edge area (third position), the action logic is the same as that of the left edge area, cutting off the negative pressure of the suction cup in the corresponding area while maintaining attraction in the remaining areas.

[0055] Throughout the process, a pressure sensor can be added. The output of the negative pressure pump can be adjusted in real time based on the signal fed back by the pressure sensor to ensure the suction force of the suction cup in the non-detection area and prevent the glass plate 6 from shifting.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

7. The rotating inspection device according to claim 1, characterized in that, It also includes a negative pressure module, which includes a negative pressure pump and a solenoid valve group. The negative pressure pump is connected to the first suction cup (422) and the second suction cup (472) respectively through an air pipe. The solenoid valve group is used to switch the negative pressure on and off of the two suction cups. The negative pressure module is linked with the shooting component (9). When the shooting component (9) moves to the corresponding shooting area, the negative pressure module controls the suction cup corresponding to that area to cut off the negative pressure and open the suction cup adsorption state of the other areas.
