Description

Technical Field

[0001] This invention relates to a surface flaw detection device and method for aluminum single-panel panels, belonging to the field of aluminum single-panel production technology. Background Technology

[0002] Aluminum single-layer panels refer to single-layer materials made by rolling aluminum ingots into rectangular sheets, followed by chromating pretreatment and fluorocarbon spraying. Quality defects such as subcutaneous porosity often occur during the production process. Therefore, defect detection is a core aspect of aluminum single-layer panel quality control. Current mainstream aluminum single-layer panel surface flaw detection devices consist of a main body, connecting wires, and a probe: the operator holds the probe against the aluminum single-layer panel surface and manually slides it to complete the inspection. However, this purely manual operation method has significant drawbacks—during probe movement, uneven operating force can easily cause gaps between the probe and the panel surface; simultaneously, manual inspection cannot guarantee complete coverage of the scanning trajectory, easily leading to blind spots and ultimately distorted inspection data, severely affecting the flaw detection effect and the quality of the aluminum single-layer panel. Summary of the Invention

[0023] The mounting box is provided with a first lifting device at the middle of its upper end, and the first lifting device is located in front of the second nut seat. The upper end of the movable part of the first lifting device is equipped with a first frame, and the other end of the connecting line passes through the first frame. The first frame is symmetrically connected to two first guide wheels, and the two first guide wheels are located at the upper and lower ends of the connecting line, respectively.

[0024] Furthermore, a slider is installed on the upper end of the mounting box, and the slider is located in front of the first lifting device. A round rod is provided between the first plate and the second plate, the round rod passes through the slider, and the round rod is slidably connected to the slider.

[0025] Furthermore, the auxiliary component includes a tray, which is movably disposed within the placement frame and located between the first lead screw and the round rod. A frame is provided at the lower end of the placement frame, and a second lifting device is installed at the middle of the lower end of the placement frame.

The guide rods are slidably connected to the placement frame, and the second lifting device and the guide rods are both located inside the frame.

[0027] Furthermore, the detector includes a housing, with an auxiliary cylinder connected to the lower end of the housing.

The lower ends of both outer cylinders are threaded with studs, which extend into the outer cylinders. The two studs are symmetrically installed on the upper end of the outer shell. Gears are provided on the upper outer ends of both outer cylinders, and the two gears mesh with each other.

[0029] A method for surface flaw detection of aluminum single-panel, using the aforementioned aluminum single-panel surface flaw detection device, includes the following steps:

[0030] The first step is to unload the material. First, use the second lifting device to drive the pallet to move up to the top of the placement frame. Then, place the aluminum panel on the top of the pallet. Then, use the second lifting device and the pallet to move the aluminum panel down into the placement frame, thereby positioning and restricting the installation of the aluminum panel.

[0031] The second step is pre-processing. The probe is moved to the initial position by the first driving device, the first lead screw, the second nut seat, the mounting box, the second driving device, the second lead screw, and the first nut seat. Then, one outer cylinder is rotated, and with the assistance of two gears, the two outer cylinders are rotated synchronously, and the two studs are moved down synchronously, thereby moving the probe and the outer shell down, so that the probe is in close contact with the aluminum single panel.

[0032] The third step is flaw detection. Using the second drive device, the second lead screw, and the first nut seat, the probe moves longitudinally along the aluminum panel. Then, using the first drive device, the first lead screw, the second nut seat, and the mounting box, the probe moves laterally along the aluminum panel a predetermined distance. The above steps are repeated to make the probe move fully along the aluminum panel. At the same time, the collected data is transmitted to the flaw detector body, and the data is analyzed and processed to obtain the information data of the aluminum panel, thus completing the flaw detection operation of the aluminum panel.

[0033] Step 4: Material handling. Using the outer cylinder and studs, the probe and auxiliary cylinder are moved to their extreme positions. Then, through the first drive device, the first lead screw, the second nut seat, the mounting box, the second drive device, the second lead screw, and the first nut seat, the probe is moved back to its initial position. Then, using the second lifting device, the pallet and aluminum panel are moved up onto the placement frame, and then the aluminum panel is removed.

[0034] The beneficial effects of this invention are:

[0035] Using two outer cylinders, two gears, two studs, and a housing, the probe is lowered and brought into close contact with the upper surface of the aluminum panel. Then, a second motor, a second lead screw, and a first nut seat move the housing forward, causing the probe to move forward along the upper surface of the aluminum panel. Once the probe reaches its forward limit, the first motor, the first lead screw, and the second nut seat move the mounting box to the left, causing the probe to move a predetermined distance to the left along the upper surface of the aluminum panel. Then, the second motor, the second lead screw, the first nut seat, and the housing move backward, causing the probe to move backward along the upper surface of the aluminum panel. This process is repeated to achieve comprehensive and precise mechanical flaw detection of the aluminum panel, effectively reducing the probability of errors in the detection data and ensuring the flaw detection effect and quality of the aluminum panel.

[0053] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0054] Example 1: As Figures 1-6 As shown, an aluminum single-panel surface flaw detection device is provided, including: a rectangular placement frame 1, a first plate 2 installed on the left end of the placement frame 1, which provides a mounting carrier for components such as a first driving device, and a second plate 6 placed on the right end of the placement frame 1, which provides a mounting carrier for components such as a mounting frame 41, and the transverse part of the mounting frame 41 with an L-shaped cross-section is installed on the right end of the second plate 6, which provides a mounting carrier for the flaw detector body 4, and the flaw detector body 4 is placed on the upper end of the mounting frame 41, through which the flaw detector body 4 processes and displays the detected data;

[0055] The first lead screw 3 is rotatably connected between the first plate 2 and the second plate 6. The second nut seat 74 moves left and right through the first lead screw 3 and is mounted on the outer end of the first lead screw 3 through a ball nut pair. The second nut seat 74 provides a mounting carrier for the mounting box 7. The fixing part of the first drive device, which connects the output shaft to the first lead screw 3, is set on the left end of the first plate 2. The first drive device drives the first lead screw 3 to rotate. The first drive device can be a first motor 31.

[0056] The mounting box 7 is installed on the lower end of the second nut seat 74. The mounting box 7 provides a mounting carrier for components such as the second drive device. The slider 71 located in front of the first lifting device is installed on the upper end of the mounting box 7. The round rod 72 that passes through the slider 71 and is slidably connected to the slider 71 is set between the first plate 2 and the second plate 6. The round rod 72 works with the slider 71 to guide the movement of the mounting box 7.

[0057] The second lead screw 76 is rotatably connected inside the mounting box 7. The first nut seat 73 moves back and forth through the second lead screw 76. The fixing part of the second drive device, which is connected to the output shaft of the second lead screw 76, is installed on the rear end of the mounting box 7. The second drive device drives the second lead screw 76 to rotate. The second drive device can be a second motor 75. The first nut seat 73, which is slidably connected inside the mounting box 7 and extends to the lower end of the mounting box 7, is connected to the outer end of the second lead screw 76 through a ball nut pair. The first nut seat 73 provides a mounting carrier for components such as the outer cylinder 84.

[0058] Two outer cylinders 84 are symmetrically rotated and connected to the lower end of the first nut seat 73. The outer cylinders 84 provide a mounting carrier for the gears 85. The two meshing gears 85 are respectively set on the upper outer ends of the two outer cylinders 84. The two gears 85 work together to make the two outer cylinders 84 rotate synchronously. Then, two studs 83 extending into the two outer cylinders 84 are respectively threaded to the lower ends of the two outer cylinders 84. The two studs 83 work together to provide a mounting carrier for the outer shell 82.

[0059] Two studs 83 are symmetrically installed on the upper end of the outer shell 82. The outer shell 82 provides a mounting carrier for components such as the auxiliary cylinder 81. The auxiliary cylinder 81, which has a trapezoidal cross-section with a wider upper section and a narrower lower section, is connected and installed on the lower end of the outer shell 82. The auxiliary cylinder 81 is used to remove impurities from the surface of the aluminum panel. The probe 8, which is located on the upper side of the placement frame 1 and has its lower end penetrating through the auxiliary cylinder 81, is installed inside the outer shell 82. The lower end face of the probe 8 coincides with the lower end face of the auxiliary cylinder 81. The probe 8 is used to collect data from the aluminum panel.

[0060] A connecting line 5, which passes through the outer shell 82 and is connected to the probe 8, and whose other end is connected to the flaw detector body 4, is installed on the outer end of the outer shell 82. The probe 8 and the flaw detector body 4 are connected through the connecting line 5. The support plate 11 located between the first lead screw 3 and the round rod 72 is movably set in the placement frame 1. The support plate 11 provides a placement carrier for the aluminum single panel. The frame 12 is then set on the lower end of the placement frame 1. The frame 12 supports the placement frame 1.

[0061] The fixed part of the second lifting device, which passes through the placement frame 1 and is connected to the tray 11 and is located in the frame 12, is installed on the lower middle part of the placement frame 1. The second lifting device drives the tray 11 to move up and down. The second lifting device can be a first electric push rod 13. Four guide rods 14, which are all located in the frame 12, extend out of the lower side of the placement frame 1 and are slidably connected to the placement frame 1, are respectively set at the four corner positions of the lower end of the tray 11. The four guide rods 14 work together to guide the movement of the tray 11.

[0062] In use, the first electric push rod 13 is started first, which drives the tray 11 to move upward and move to the upper side of the placement frame 1. Then, the aluminum single panel to be tested is placed on the upper end of the tray 11. Then, the first electric push rod 13 is used to move the tray 11 down to its original position, which causes the placed aluminum single panel to move down and enter the placement frame 1, thereby positioning and restricting the installation of the aluminum single panel.

[0063] Then, the first motor 31 is started, which drives the first lead screw 3 to rotate. Since the first lead screw 3 is connected to the second nut seat 74 through a ball nut pair, the rotation of the first lead screw 3 causes the second nut seat 74 to move to the left, thereby moving the mounting box 7 and other components to the left to the appropriate position. Then, the second motor 75 is started, which drives the second lead screw 76. Since the second lead screw 76 is connected to the first nut seat 73 through a ball nut pair, the rotation of the second lead screw 76 causes the first nut seat 73 to move backward, thereby moving the outer shell 82 and the probe 8 and other components to the appropriate position, thereby moving the probe 8 to the initial position.

[0064] Then, one outer cylinder 84 is rotated, which causes the corresponding gear 85 to rotate. Since the two gears 85 mesh with each other, the rotation of one gear 85 will cause the other gear 85 to rotate, which in turn causes the two outer cylinders 84 to rotate synchronously. Since the outer cylinder 84 is threadedly connected to the stud 83, the rotation of the outer cylinder 84 will cause the stud 83 to move down, which in turn causes the outer shell 82 to move down, thereby causing the probe 8 to move down and make close contact with the upper surface of the aluminum single plate.

[0065] Then, using the second motor 75, the second lead screw 76, and the first nut seat 73, the outer casing 82 and other components move forward, thereby causing the probe 8 to move forward along the upper surface of the aluminum single panel. When the probe 8 moves to the front limit position, the first motor 31, the first lead screw 3, and the second nut seat 74 are used to move the mounting box 7 and other components to the left, thereby causing the probe 8 to move to the left a predetermined distance along the upper surface of the aluminum single panel. Then, the second motor 75, the second lead screw 76, the first nut seat 73, and the outer casing 82 and other components move backward, thereby causing the probe 8 to move backward along the upper surface of the aluminum single panel.

[0066] Then, the above steps are repeated, so that the probe 8 moves fully on the surface of the aluminum panel. During the movement, the auxiliary cylinder 81 also moves along the surface of the aluminum panel. The auxiliary cylinder 81 is used to push away the impurities remaining on the area to be inspected on the aluminum panel. At the same time, the probe 8 collects information data of the aluminum panel and transmits the collected data to the flaw detector body 4 through the connecting line 5. The flaw detector body 4 then analyzes and displays the data, thereby completing the flaw detection operation on the aluminum panel. This achieves a comprehensive and precise mechanical flaw detection operation on the aluminum panel, effectively reducing the probability of errors in the detection data and effectively ensuring the flaw detection effect and quality of the aluminum panel.

[0067] After the flaw detection operation is completed, the outer shell 82 and the probe 8 are moved to their extreme positions using two outer cylinders 84, two studs 83, and two gears 85. Then, the probe 8 is moved back to its original position using components such as the first motor 31, the first lead screw 3, the second nut seat 74, the second motor 75, the second lead screw 76, and the first nut seat 73. Then, the aluminum panel is pushed upwards onto the placement frame 1 using the first electric push rod 13 and the support plate 11. The aluminum panel is then removed, enabling convenient disassembly and assembly of the aluminum panel, effectively reducing the probability of damage to the aluminum panel, and effectively ensuring safety, flaw detection effect, and work efficiency.

[0068] Example 2: Figure 1 , Figure 2 and Figure 7 As shown, the fixing part of the first lifting device located in front of the second nut seat 74 is set on the upper middle part of the mounting box 7. The first lifting device drives the first frame 51 to move up and down. The first lifting device can be a second electric push rod 53. The first frame 51 is installed on the upper part of the movable part of the first lifting device. The first frame 51 provides a mounting carrier for the first guide wheel 52. The second frame 55 is set on the left middle part of the mounting box 7. The second frame 55 provides a mounting carrier for the second guide wheel 54.

[0069] The other end of the connecting line 5 passes through the first frame 51 and the second frame 55 and is connected to the flaw detector body 4. The two second guide wheels 54 located at the front and rear ends of the connecting line 5 are symmetrically rotated and connected in the second frame 55. The two first guide wheels 52 located at the upper and lower ends of the connecting line 5 are symmetrically rotated and connected in the first frame 51. The two first guide wheels 52 and the two second guide wheels 54 work together to guide the connecting line 5.

[0070] In use, the first electric push rod 13 is used to move the tray 11 up to the upper side of the placement frame 1. Then the aluminum single panel to be tested is placed on the upper end of the tray 11. The first electric push rod 13 is used to move the tray 11 down to its original position, thereby moving the placed aluminum single panel down and into the placement frame 1, thereby positioning and restricting the installation of the aluminum single panel.

[0071] Then, using the first motor 31, the first lead screw 3, and the second nut seat 74, the mounting box 7 and other components are moved to the left to a suitable position. Then, using the second motor 75, the second lead screw 76, and the first nut seat 73, the outer shell 82 and the probe 8 are moved to a suitable position, so that the probe 8 moves to the initial position. Then, using the two outer cylinders 84, the two studs 83, and the two gears 85, the outer shell 82 and the probe 8 are moved down, so that the probe 8 makes close contact with the upper surface of the aluminum single panel.

[0072] Then, using components such as the second motor 75, the second lead screw 76, the first nut seat 73, the first motor 31, the first lead screw 3, the second nut seat 74, and the mounting box 7, the probe 8 moves fully on the surface of the aluminum panel. At this time, the probe 8 collects information data of the aluminum panel and transmits the collected data to the flaw detector body 4 through the connecting line 5. Then, the flaw detector body 4 analyzes and displays the data, thereby completing the flaw detection operation on the aluminum panel.

[0073] During the flaw detection movement, when the first nut seat 73 moves back and forth, it will cause the probe 8 to move back and forth, thereby pulling the connecting wire 5. At this time, the two second guide wheels 54 guide the pulling of the connecting wire 5, and at the same time, the second electric push rod 53 is activated, which causes the first frame 51 to move up and down, and then the two first guide wheels 52 to move up and down, thereby pulling or releasing the connecting wire 5 outward, so that the connecting wire 5 is always taut and outside the mounting box 7.

[0074] As the mounting box 7 moves to the left, the probe 8 will also move to the left, thus pulling the connecting wire 5. At this time, the two first guide wheels 52 guide the outward pull of the connecting wire 5. Simultaneously, the second electric push rod 53 and the first frame 51 are used to move the two first guide wheels 52 downward, so that the connecting wire 5 is always taut and outside the mounting box 7. Then, the above steps are repeated. During the full flaw detection process of the probe 8, the connecting wire 5 is always taut and outside the mounting box 7, so as to realize the real-time tidying of the connecting wire 5 during flaw detection, effectively reducing the probability of knots or damage to the connecting wire 5, effectively reducing the probability of obstruction of the probe 8 during flaw detection, and effectively ensuring the flaw detection effect and work efficiency.

[0075] After the flaw detection operation is completed, the outer shell 82 and the probe 8 are moved to their extreme positions using two outer cylinders 84, two studs 83 and two gears 85. Then, the probe 8 is moved back to its original position using the first motor 31, the first lead screw 3, the second nut seat 74, the second motor 75, the second lead screw 76 and the first nut seat 73. Then, the aluminum panel is pushed upwards onto the placement frame 1 using the first electric push rod 13 and the support plate 11. Finally, the aluminum panel is removed.

[0076] A method for surface flaw detection of aluminum single-panel, using the aforementioned aluminum single-panel surface flaw detection device, includes the following steps:

[0077] Step 1: Material placement. First, use the first electric push rod 13 to drive the tray 11 to move up to the top of the placement frame 1. Then, place the aluminum panel on the top of the tray 11. Then, through the first electric push rod 13 and the tray 11, move the aluminum panel down into the placement frame 1, thereby positioning and restricting the installation of the aluminum panel.

[0078] The second step is pre-processing. The probe 8 is moved to the initial position by the first motor 31, the first lead screw 3, the second nut seat 74, the mounting box 7, the second motor 75, the second lead screw 76, and the first nut seat 73. Then, one outer cylinder 84 is rotated, and with the assistance of two gears 85, the two outer cylinders 84 are rotated synchronously, and the two studs 83 are moved down synchronously, thereby moving the probe 8 and the outer shell 82 down, so that the probe 8 is in close contact with the aluminum single panel.

[0079] The third step is flaw detection. Using the second motor 75, the second lead screw 76, and the first nut seat 73, the probe 8 is moved longitudinally along the aluminum panel. Then, using the first motor 31, the first lead screw 3, the second nut seat 74, and the mounting box 7, the probe 8 is moved laterally along the aluminum panel a predetermined distance. The above steps are repeated to make the probe 8 move fully along the aluminum panel. At the same time, the collected data is transmitted to the flaw detector body 4, and the data is analyzed and processed to obtain the information data of the aluminum panel, thereby completing the flaw detection operation of the aluminum panel.

[0080] Step 4: Material handling. Using the outer cylinder 84 and stud 83, the probe 8 and auxiliary cylinder 81 are moved to their extreme positions. Then, through the first motor 31, the first lead screw 3, the second nut seat 74, the mounting box 7, the second motor 75, the second lead screw 76, and the first nut seat 73, the probe 8 is moved to its initial position. Then, using the first electric push rod 13, the pallet 11 and the aluminum panel are moved up onto the placement frame 1, and then the aluminum panel is removed.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

8. A method for surface flaw detection of aluminum single-panel, using the surface flaw detection device for aluminum single-panel as described in claim 7, characterized in that, Includes the following steps: First step, material placement: First, use the second lifting device to drive the pallet (11) to move up to the top of the placement frame (1), then place the aluminum panel on the upper end of the pallet (11), and then use the second lifting device and the pallet (11) to move the aluminum panel down into the placement frame (1), thereby positioning and restricting the installation of the aluminum panel. The second step is pre-processing. The probe (8) is moved to the initial position by the first driving device, the first lead screw (3), the second nut seat (74), the mounting box (7), the second driving device, the second lead screw (76), and the first nut seat (73). Then, one outer cylinder (84) is rotated, and with the assistance of two gears (85), the two outer cylinders (84) are rotated synchronously, and the two studs (83) are moved down synchronously, thereby causing the probe (8) and the outer shell (82) to move down, so that the probe (8) is in close contact with the aluminum single panel. The third step is flaw detection. Using the second drive device, the second lead screw (76) and the first nut seat (73), the probe (8) is moved longitudinally along the aluminum single panel. Then, using the first drive device, the first lead screw (3), the second nut seat (74) and the mounting box (7), the probe (8) is moved laterally along the aluminum single panel for a predetermined distance. The above steps are repeated so that the probe (8) moves along the aluminum single panel in a full range. At the same time, the collected data is transmitted to the flaw detector body (4) and the data is analyzed and processed to obtain the information data of the aluminum single panel, thereby completing the flaw detection operation of the aluminum single panel. Step 4: Material handling. Using the outer cylinder (84) and stud (83), the probe (8) and auxiliary cylinder (81) are moved to their extreme positions. Then, through the first drive device, the first lead screw (3), the second nut seat (74), the mounting box (7), the second drive device, the second lead screw (76), and the first nut seat (73), the probe (8) is moved to its initial position. Then, using the second lifting device, the pallet (11) and aluminum panel are moved up onto the placement frame (1), and then the aluminum panel is removed.
