[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: like Figure 1-5 As shown, this embodiment proposes a testing device for aerogel-coated thermal insulation sheets, comprising: Multiple sets of swivel wheels 1; Processing rack 8; The processing rack 8 is set above multiple sets of casters 1, and a loading trolley 3 is provided at the bottom of the processing rack 8; Cylinder 5; The cylinder 5 is mounted on the loading trolley 3, and the output end of the cylinder 5 is connected to the air rod 6. The top end of the air rod 6 is provided with a lifting plate 7. Multiple sets of connecting columns 10; the multiple sets of connecting columns 10 are vertically arranged on the top of the processing frame 8, and the top of the multiple sets of connecting columns 10 are connected to the top plate 11; Drive component 24; the drive component 24 is disposed at the bottom of the top plate 11; Material picking vacuum suction cup 17; the material picking vacuum suction cup 17 is provided with a threaded sleeve 37, which is connected to the drive assembly 24; Conveying mechanism 13; the conveying mechanism 13 is disposed on the side of the processing frame 8, and the first detection frame 14, the flipping mechanism 16 and the second detection frame 15 are sequentially arranged on the conveying mechanism 13; a bottom frame 12 is provided below the conveying mechanism 13; Two sets of cameras 20; the two sets of cameras 20 are respectively mounted on the first detection frame 14 and the second detection frame 15; Thickness gauge 22; the thickness gauge 22 is mounted on the second detection frame 15 and is used to measure the thickness of the sheet material; The processing frame 8 has a material picking port 9, the size of which is larger than the projected size of the lifting plate 7.

[0020] In this embodiment, The test pieces are stacked on the lifting plate 7 of the loading trolley 3. The cylinder 5 is activated to drive the air rod 6 to lift vertically, raising the pieces to the picking port 9 of the processing rack 8. Then, the drive assembly 24 controls the picking vacuum suction cup 17 to move along the bottom of the top plate 11 to directly above the picking port 9, adsorbing the pieces and transferring them to the starting end of the conveying mechanism 13. At the same time, the conveying mechanism 13 conveys the pieces to the area below the first inspection rack 14, where the camera 20 captures a front image of the pieces to detect surface foreign objects and coating integrity. The pieces are then held and rotated 180° by the flipping mechanism 16, and then the camera 20 of the second inspection rack 15 captures a reverse image. Simultaneously, the side thickness gauge 22 measures the thickness of the pieces at multiple points. After the inspection is completed, the conveying mechanism 13 outputs the pieces to the sorting area, completing a single inspection cycle. The lifting plate 7 of the integrated feeding trolley 3 is linked with the cylinder 5 for automatic lifting and positioning of the material sheet. Combined with the drive component 24, the material picking vacuum suction cup 17 moves along the top plate 11 on multiple axes, completing efficient material picking and feeding. The conveying mechanism 13 and the flipping mechanism 16 work together to allow the material sheet to pass through the dual cameras 20 of the first inspection frame 14 and the second inspection frame 15 for front and back coating defect detection. The side thickness gauge 22 is used to simultaneously perform multi-point thickness measurement, forming an integrated inspection process. The device, through the rigid support design of the universal wheels 1 and the bottom frame 12, takes into account both mobility and operational stability, significantly improving the inspection efficiency and accuracy of aerogel coated heat insulation material sheets, covering the fully automatic judgment of key quality indicators such as surface foreign objects, coating bubbles, and thickness tolerance.

[0021] Specifically, the drive assembly 24 includes a fixing plate 29, on which a first threaded rod 32 and a second threaded rod 33 are provided. A sliding block 30 is provided between the first threaded rod 32 and the second threaded rod 33. The first threaded rod 32 and the second threaded rod 33 are provided through the sliding block 30, and the first threaded rod 32 and the second threaded rod 33 are threadedly engaged with the sliding block 30. A rotating rod 28 is rotatably mounted on the fixed plate 29. The rotating rod 28 passes through the sliding block 30 and is slidably mounted on the rotating rod 28. Multiple sets of protrusions 41 are evenly arranged on the outer wall of the rotating rod 28. Both the first threaded rod 32 and the second threaded rod 33 are provided with pulleys 35, and a transmission belt 34 is provided between the two sets of pulleys 35.

[0022] In this embodiment, the drive assembly 24 achieves precise linear displacement of the sliding block 30 in the horizontal direction through the threaded engagement of the first threaded rod 32 and the second threaded rod 33 arranged parallel on the fixed plate 29 with the sliding block 30, combined with the synchronous drive structure of the pulley 35 and the transmission belt 34, thus avoiding the cumulative error caused by single-axis transmission; the rotating rod 28 passes through the sliding block 30 and engages with the protrusion 41, and intermittent contact friction is formed through the protrusion on the outer wall of the rotating rod 28 when the sliding block 30 moves, thereby enhancing the dynamic stability of the sliding block 30 in compound motion; This enables the vacuum suction cup 17 to achieve precise multi-degree-of-freedom positioning in three-dimensional space, while reducing the structural complexity of the drive component 24 and significantly improving the repeatability and motion efficiency of the material picking and placing and the detection path.

[0023] Specifically, the driving component 24 further includes: Two sets of fixing blocks 25; the two sets of fixing blocks 25 are respectively locked to the top plate 11 by bolts; First motor 26; the first motor 26 is mounted on a set of fixed blocks 25, and the rotating rod 28 is connected to the first motor 26 in a transmission connection; Second motor 31; the second motor 31 is mounted on another set of fixed blocks 25, and the first threaded rod 32 is connected to the second motor 31 in a transmission connection; The third threaded rod 38; the sliding block 30 is provided with a movable cavity, and the third threaded rod 38 is rotatably disposed in the movable cavity; a first bevel gear 39 is provided on the third threaded rod 38; The second bevel gear 40 is disposed on the outer wall of the rotating rod 28; the second bevel gear 40 meshes with the first bevel gear 39.

[0025] In this embodiment, the drive assembly 24 is bolted to the top plate 11 by two sets of fixing blocks 25, ensuring the independent drive stability of the first motor 26 and the second motor 31, and realizing multi-axis collaborative control of the rotating rod 28, the first threaded rod 32, and the second threaded rod 33; through the threaded engagement of the third threaded rod 38 with the connecting block 36 in the movable cavity, combined with the meshing transmission of the first bevel gear 39 and the second bevel gear 40 on the outer wall of the rotating rod 28, the circumferential rotation of the rotating rod 28 is converted into the vertical lifting motion of the third threaded rod 38, thereby increasing the displacement freedom of the material picking vacuum suction cup 17 for multi-directional precise positioning; Of course, the limiting component 27 constrains the ends of the first threaded rod 32, the second threaded rod 33 and the rotating rod 28, effectively limiting the stroke range of the sliding block 30, avoiding transmission overload, and improving the reliability and repeatability of the device. This structure simplifies the mechanical complexity of multi-degree-of-freedom drive through modular motor layout and composite transmission design, while ensuring the efficiency and stability of the material picking and placing and detection path.

[0027] Specifically, the flipping mechanism 16 includes a pneumatic gripper and a rotary motor for gripping the material and rotating it 180° to achieve double-sided inspection.

[0028] Specifically, the thickness gauge 22 is a laser thickness sensor, and the measurement direction of the thickness gauge 22 is perpendicular to the conveying plane of the conveying mechanism 13; The conveying mechanism 13 includes two sets of belt conveyors, which are respectively located below the first inspection frame 14 and the second inspection frame 15.

[0029] Specifically, both the first testing frame 14 and the second testing frame 15 are provided with a loading position 23 at the bottom for positioning the material to be tested; A double-layer detection head 18 is installed on one side of the top plate 11 to assist in detecting foreign objects and film bubbles on the surface of the material sheet.

[0030] In this embodiment, when clamping the sheet, the pneumatic gripper clamps the edge of the sheet, and the rotary motor drives the sheet to rotate 180°; the flipped sheet is released to the loading position 23 of the second inspection frame 15 to ensure that the reverse side is parallel to the shooting plane of the camera 20; the side thickness gauge 22 performs multi-point thickness measurement when the sheet is stationary, and compares it with the preset tolerance range to determine the pass rate.

[0031] A method for using a testing device for aerogel-coated thermal insulation sheets includes the following steps: Step A: Stack the sheet to be tested on the lifting plate 7 of the loading trolley 3, and lift it by the cylinder 5 driving the air rod 6 to raise the sheet to the material picking port 9 of the processing rack 8; Step B: Drive component 24 controls the material picking vacuum suction cup 17 to move above the material picking port 9, pick up the material sheet and transfer it to the loading position 23 of the conveying mechanism 13; Step C: The conveying mechanism 13 conveys the sheet material sequentially to the bottom of the first inspection frame 14, and the camera 20 captures a front image of the sheet material to detect foreign objects and coating bubbles on the surface.
