Description

Technical Field

[0001] This invention relates to the field of optical inspection equipment technology, specifically to an inspection device and method for the production and processing of air shield dams. Background Technology

[0002] Air-shield dams (also known as airbag shield dams or air-shield gates) are a new type of movable hydraulic structure that combines flexible airbags with rigid shield plates. They combine the simplicity of rubber dams with the impact resistance of steel gates and are widely used in river flood control, water storage, landscaping, and ecological restoration.

[0003] The core technology and component of air-supported dams is the rubber airbag. However, because the rubber airbags used in air-supported dams are large rubber products, although the manufacturing processes, technologies and production equipment are different, the rubber airbags need to undergo multiple processes during production and processing to prevent defects such as micro-cracks, missing glue, and scratches on their surface, which would affect the normal use of the airbags. Currently, in the production and processing of airbags for air-supported dams, online inspection of the airbags is achieved through visual inspection devices to avoid safety and economic risks such as air leakage, tearing, and failure during later installation and use.

[0004] In existing technologies, during the surface inspection process of airbag production for air dams, when inspecting some larger airbags, the size of some airbags exceeds the load-bearing capacity and inspection boundaries of standard inspection tables, making it impossible to use conventional fixed visual inspection equipment. Therefore, gantry-type moving optical equipment is commonly used for on-site inspection. The airbag to be inspected is placed below the inspection area of ​​the gantry-type moving optical equipment, and then the airbag is moved and rotated by a drive component, allowing the visual inspection device to perform a full-area scan of the airbag surface. However, since airbags for air dams often use a black multi-layer composite rubber structure, the black rubber material itself has the characteristics of low reflectivity and low contrast, resulting in insufficient image clarity during optical inspection and difficulty in effectively distinguishing defects from background areas. This may lead to a decrease in the accuracy of the visual inspection device in identifying defects on the airbag surface, and problems such as missed detections and false detections may occur, affecting the accuracy and reliability of the inspection results and failing to meet the quality requirements in the airbag production process. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a testing device and method for the production and processing of air-supported dams, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a testing device for the production and processing of air-supported dams, comprising a testing box, a gantry frame above the testing box, an optical testing device installed at the center of the lower surface of the gantry frame, a clamping assembly for moving airbags located below the optical testing device on the gantry frame, a blowing assembly on one side of the gantry frame, and a spraying assembly for spraying foaming agent onto the surface of the airbags on the side of the gantry frame away from the blowing assembly; The spraying assembly includes two sets of sleeves fixedly connected to the gantry frame. One end of each set of sleeves is slidably connected to a sliding rod. A fixed tube is fixedly connected between the two sets of sliding rods. Multiple atomizing nozzles are connected to the outer wall of the fixed tube.

[0007] Preferably, the ends of both sets of sleeves away from the fixed tube are connected to connecting hoses, and a liquid storage tank is provided at the end of the outer wall of the detection box, with the end of the connecting hose away from the sleeve connected to the liquid storage tank.

[0008] Preferably, a return spring is fixedly sleeved on the outer wall of the slide rod, and the return spring is fixedly connected to the sleeve. A connecting rod is fixedly connected to one end of the return spring on the outer wall of the slide rod. Two sets of corrugated plates are symmetrically fixedly connected to the inner walls on both sides of the detection box. The connecting rod is in continuous contact with the surface of the corrugated plate.

[0009] Preferably, the clamping assembly includes two sets of mounting plates, each set of mounting plates having a gear fixedly connected to the center of one side surface, and racks fixedly connected to the inner walls of both sides of the detection box below the corrugated plate, with the gears meshing with the racks.

[0010] Preferably, two sets of electric push rods are symmetrically fixedly connected to the side surface of the two sets of mounting plates away from the gears, and a clamping block is fixedly connected to the end of each set of electric push rods away from the mounting plate. Multiple sets of rollers are rotatably connected to the inner wall of each clamping block.

[0011] Preferably, an arc-shaped sleeve is provided at the center of the two sets of mounting plates. The inner wall of the arc-shaped sleeve is provided with a groove, and multiple sets of transmission rollers are provided on the inner wall of the groove. The multiple sets of transmission rollers are connected to the driving component through a synchronous belt. A transmission rod is slidably connected between the mounting plate and the gear. One end of the transmission rod is fixedly connected to the arc-shaped sleeve, and the other end of the transmission rod is fixedly connected to the gantry frame.

[0012] Preferably, the blower assembly includes a blower hood, which is located on the side of the gantry away from the fixed tube, and the blower hood is connected to the gantry via a rotating rod.

[0013] Preferably, the foaming agent is a high-purity, low-carbon alcohol-based water-based microbubble agent. The optical detection device is connected to the control terminal via a wire. The control terminal includes an imaging device for real-time display of bubbles and an intelligent identification module for real-time identification of coded information for marking and positioning.

[0014] A testing method for the production and processing of air-supported dams includes the following steps: S1: Airbag positioning: Place the uninflated airbag between the two sets of clamping blocks inside the testing box, inflate the airbag to make it expand and deform, and stop the inflation operation after the outer wall of the airbag is in contact with the two sets of clamping blocks to complete the positioning and clamping of the airbag. S2: Airbag Movement: The airbag is moved by the gantry frame and clamping components. The meshing transmission of gears and racks drives the mounting plate, clamping blocks and airbag to rotate synchronously. At the same time, the transmission rollers assist the clamping blocks to drive the airbag to rotate stably, ensuring that the airbag movement and rotation are synchronized. S3: Airbag pretreatment: During the movement and rotation of the airbag, the blower continuously sprays airflow onto the surface of the airbag to remove dust, sand and other impurities attached to the surface of the airbag, so as to avoid impurities interfering with the accuracy of subsequent detection. After the airbag completes one rotation, the blower stops working. S4: Foaming agent spraying: After the blower stops working, the connecting hose delivers the foaming agent in the storage tank to the fixed pipe, and then sprays it onto the surface of the airbag after atomization by the atomizing nozzle, so that a thin and uniform microbubble layer is formed on the surface of the airbag. During the spraying process, the atomizing nozzle moves back and forth horizontally to expand the spray coverage area. S5: Blind Spot Avoidance: During the spraying of the foaming agent, the electric push rod drives the clamping block to move along the surface of the airbag, and performs a comprehensive inspection of the airbag area that is blocked by the clamping block, reducing the blind spot. The gantry moves the airbag to the end of the inspection box and then continues to move and reset, thus completing the comprehensive inspection of the airbag. After the airbag has been inspected, it can be deflated and taken out.

[0015] In summary, the present invention has the following main beneficial effects: 1. This invention uses an atomizing nozzle to spray a foaming agent onto the surface of the airbag. The microbubble layer generated by the foaming agent on the airbag surface significantly enhances the grayscale contrast between defective and normal areas on the airbag surface, strengthens the imaging clarity of minor defects such as cracks, pinholes, and local damage, and makes the defect outline easier for the visual inspection system to capture and identify. This improves imaging stability and defect recognition to a certain extent. At the same time, through the synergistic action of the corrugated plate, slide bar, sleeve, and return spring, the fixed tube drives the atomizing nozzle to move left and right while moving with the airbag, so that the foaming agent is evenly covered on the outer surface of the airbag in atomized form. This effectively avoids local accumulation, liquid accumulation, and dripping, and ensures that a uniform and evenly distributed microbubble layer is formed on the airbag surface. This minimizes the problems of abnormal reflection, grayscale distortion, and local occlusion caused by uneven spraying of the foaming agent. 2. This invention uses clamping blocks to hold and position the airbag. As the airbag moves with the gantry, it rotates using the meshing of gears and racks. Simultaneously, a synchronous belt drives multiple sets of transmission rollers to rotate synchronously, assisting the airbag's rotation. The arc-shaped sleeve and transmission rollers provide support for the airbag to a certain extent, ensuring stable rotation during movement. This facilitates the optical inspection equipment's detection of the airbag surface. During the spraying of the foaming agent, an electric push rod drives the clamping blocks to adaptively translate along the airbag surface, exposing the airbag area originally blocked by the clamping blocks to the inspection field of view. This achieves full-surface coverage inspection, eliminates blind spots caused by fixed clamping, ensures the airbag is sprayed with foaming agent and completes imaging recognition, and improves the comprehensiveness and completeness of the inspection. 3. By setting up a blower hood, the present invention continuously blows air onto the surface of the airbag before spraying the foaming agent, which can remove dust, sand and other adhering objects in advance, avoid impurities from interfering with the imaging process or causing false defects, and further ensure the authenticity and reliability of the imaging.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] A testing device used in the production and processing of air-supported dams, such as Figure 1 - Figure 7 As shown, the device includes a testing box 1, a gantry frame 2 on top of the testing box 1, a threaded rod on the outer wall of the testing box 1, the gantry frame and the threaded rod being slidably connected, and a limiting rod on the side of the outer wall of the testing box 1 away from the threaded rod. The threaded rod is rotated by a drive motor, which in turn works with the limiting rod to move the gantry frame 2. An optical inspection device 3 is installed at the center of the lower surface of the gantry frame 2. The optical inspection device 3 can be moved by the gantry frame 2. A spraying component for spraying a foaming agent onto the surface of the airbag is provided on the side of the gantry frame 2 away from the blowing assembly. The spraying assembly includes two sets of sleeves 54 fixedly connected to the gantry 2. One end of each set of sleeves 54 is slidably connected to a slide rod 53. A fixed tube 51 is fixedly connected between the two sets of slide rods 53. Multiple atomizing nozzles 52 are connected to the outer wall of the fixed tube 51. The foaming agent inside the fixed tube 51 is sprayed onto the surface of the airbag through the atomizing nozzles 52, thereby replicating the image of the optical inspection equipment 3. Both sets of sleeves 54 are connected to a connecting hose 57 at the end away from the fixed pipe 51. A liquid storage tank is provided at the end of the outer wall of the test box 1. The end of the connecting hose 57 away from the sleeve 54 is connected to the liquid storage tank. A pump body is installed inside the liquid storage tank at the contact position with the connecting hose 57. By starting the pump body, the foaming agent inside the liquid storage tank can be transferred to the inside of the fixed pipe 51 through the connecting hose 57 for use. A return spring is fixedly sleeved on the outer wall of the slide rod 53, and the return spring is fixedly connected to the sleeve 54. A connecting rod 55 is fixedly connected to one end of the return spring on the outer wall of the slide rod 53. A certain pressure can be applied to the slide rod 53 by means of the return spring. Two sets of corrugated plates 56 are symmetrically fixedly connected to the inner walls on both sides of the test box 1. The corrugated plates 56 include multiple bending units connected in sequence. Each bending unit has a bending part. The bending amplitude of each bending part is the same, and the bending direction is alternately set. The bending direction of the two sets of corrugated plates 56 is the same. The connecting rod 55 is in continuous contact with the surface of the corrugated plate 56. Through the bending unit on the surface of the corrugated plate 56, the connecting rod 55 can drive the fixed tube 51 to move back and forth, so that the atomizing nozzle 52 can spray the foaming agent evenly.

[0020] See Figure 5 - Figure 7 It can be seen that the gantry 2 is located below the optical inspection equipment 3 and is equipped with a clamping assembly that drives the airbag to move. The clamping assembly includes two sets of mounting plates 61. Gears 66 are fixedly connected to the center of one side surface of each of the two sets of mounting plates 61. Racks 68 are fixedly connected to the inner walls of both sides of the inspection box 1 below the corrugated plate 56. The gears 66 and racks 68 mesh. A transmission rod 67 is slidably connected between the mounting plate 61 and the gear 66. One end of the transmission rod 67 is fixedly connected to the arc-shaped sleeve block 64, and the other end of the transmission rod 67 is fixedly connected to the gantry frame 2. When the gantry frame 2 drives the mounting plate 61 to move, the mounting plate 61 can be driven to rotate through the meshing transmission of the gear 66 and the rack 68, which in turn drives the airbag to rotate when it moves, so as to facilitate the uniform spraying of the foaming agent on the surface of the airbag. Two sets of electric push rods 62 are symmetrically fixedly connected to the side surface of the two sets of mounting plates 61 away from the gear 66. The end of each set of electric push rods 62 away from the mounting plate 61 is fixedly connected to a clamping block 63. Multiple sets of rollers 631 are rotatably connected to the inner wall of the clamping block 63. The clamping block 63 can clamp the airbag, thereby facilitating the movement of the airbag. When the electric push rod 62 drives the clamping block 63 to move, the rollers 631 facilitate the movement of the clamping block 63 and reduce friction. An arc-shaped sleeve 64 is provided at the center of the two sets of mounting plates 61. The inner wall of the arc-shaped sleeve 64 has a slot, and multiple sets of transmission rollers 65 are provided on the inner wall of the slot. The multiple sets of transmission rollers 65 are connected to the drive component through a synchronous belt. The synchronous belt drives the multiple sets of transmission rollers 65 to rotate synchronously, which assists the rotation of the airbag with the cooperation of gear 66 and rack 68. At the same time, the arc-shaped sleeve 64 can support the middle position of the airbag to prevent the airbag from contacting the bottom surface of the detection box 1 due to gravity, thus affecting the subsequent movement of the airbag.

[0021] See Figure 1 - Figure 3 It is known that a blowing assembly is provided on one side of the gantry 2. The blowing assembly includes a blowing hood 41. The blowing hood 41 is located on the side of the gantry 2 away from the fixed tube 51. The blowing hood 41 is connected to the gantry 2 through a rotating rod 42. After the airbag is placed on the clamping block 63 and inflated, the rotating rod 42 can be rotated by the drive motor to drive the blowing hood 41 to reset. The blowing hood 41 sprays airflow onto the surface of the airbag to remove floating dust, sand and other impurities attached to the surface of the airbag, so as to avoid impurities interfering with the subsequent detection accuracy. After the detection is completed, the blowing hood 41 is rotated upward by the drive motor in conjunction with the rotating rod 42, so that the airbag can be taken out from the inside of the detection box 1.

[0022] See Figure 1 It is known that the foaming agent is a high-purity, low-carbon alcohol-based water-based microbubble agent. The optical inspection device 3 is connected to the control terminal via wires. The control terminal includes an imaging device for real-time display of bubbles (location of air bladder leakage, scratches, defects, etc.) and an intelligent identification module for real-time identification of coded information for marking and positioning.

[0023] A testing method for the production and processing of air-supported dams includes the following steps: S1: Airbag positioning: Place the uninflated airbag between the two sets of clamping blocks 63 inside the detection box 1, inflate the airbag to make it expand and deform, and stop the inflation operation after the outer wall of the airbag is in contact with the two sets of clamping blocks 63. The positioning and clamping of the airbag can be completed. S2: Airbag movement: The airbag is moved by the gantry frame 2 in conjunction with the clamping assembly. The meshing transmission of gear 66 and rack 68 drives the mounting plate 61, clamping block 63 and airbag to rotate synchronously. At the same time, the transmission roller 65 assists the clamping block 63 to drive the airbag to rotate stably, ensuring that the movement and rotation of the airbag are synchronized. S3: Airbag pretreatment: During the movement and rotation of the airbag, the blower hood 41 continuously sprays airflow onto the surface of the airbag to remove dust, sand and other impurities attached to the surface of the airbag, so as to avoid impurities interfering with the accuracy of subsequent detection. After the airbag completes one rotation, the blower hood 41 stops working. S4: Foaming agent spraying: After the blower hood 41 stops working, the connecting hose 57 delivers the foaming agent in the storage tank to the fixed pipe 51, and then sprays it onto the surface of the airbag after atomization treatment by the atomizing nozzle 52, so that a thin and uniform microbubble layer is formed on the surface of the airbag. During the spraying process, the atomizing nozzle 52 moves back and forth horizontally to expand the spray coverage area. S5: Blind spot avoidance: During the foaming agent spraying operation, the electric push rod 62 drives the clamping block 63 to move along the surface of the airbag, and performs a comprehensive inspection of the airbag area clamped and blocked by the clamping block 63 to reduce the blind spot. The gantry 2 drives the airbag to the end of the inspection box 1 and then continues to move and reset, thus completing the comprehensive inspection of the airbag. After the airbag has been inspected, it can be deflated and taken out.

[0024] The working principle of this invention is as follows: When performing airbag testing, the airbag in an uninflated state is first placed inside the testing box 1, and the airbag is placed between two sets of clamping blocks 63. Then, the inflation device is started to inflate the airbag, causing it to expand and deform. When the outer wall of the airbag is in contact with and positioned by the two sets of clamping blocks 63, the inflation operation is stopped. After inflation is completed, the rotating rod 42 is driven to rotate by the drive motor, which drives the blower cover 41 to return to the preset working position. Then, the threaded rod is driven to rotate by the drive motor, and the limit rod drives the gantry 2 to move. The gantry 2 drives the clamped airbag to move along the preset trajectory. As the airbag moves with the gantry 2, the gear 66 and the rack 68 are in a meshing state. Under the meshing transmission of the rack 68, the gear 66 rotates synchronously, which in turn drives the mounting plate 61 and the clamping block 63 fixed to it to rotate synchronously, realizing the rotation of the airbag. At the same time, the drive unit drives multiple sets of transmission rollers 65 to rotate synchronously through the synchronous belt, and the clamping block 63 drives the airbag to rotate, so that the airbag can rotate stably while moving along the preset trajectory. During this process, the blower hood 41 continuously sprays airflow onto the surface of the airbag to thoroughly remove the floating dust, sand and other impurities attached to the surface of the airbag, so as to avoid the impurities from interfering with the subsequent detection accuracy of the airbag. After the airbag completes one rotation, the blower hood 41 stops working. At this time, the pump starts and delivers the foaming agent stored in the storage tank to the fixed tube 51 through the connecting hose 57. After being guided by the fixed tube 51, the foaming agent is atomized by the atomizing nozzle 52 and evenly sprayed onto the surface of the airbag, so that a thin and uniform microbubble layer is formed on the surface of the airbag. Through the action of the foaming agent, the grayscale contrast between the defect area and the normal area on the surface of the airbag can be effectively increased, significantly improving the imaging clarity of small defects such as cracks and pinholes, thereby indirectly improving the accuracy of airbag detection. During the spraying of the foaming agent, the atomizing nozzle 52 moves synchronously with the gantry 2 along the direction of airbag movement. During the movement, with the guidance of the corrugated plate 56, the connecting rod 55 fixed on the outer wall of the slide rod 53 at both ends of the atomizing nozzle 52 always keeps in close contact with the corrugated plate 56. Under the elastic reset action of the return spring, the slide rod 53 is driven to slide back and forth on the inner wall of the sleeve 54, thereby driving the atomizing nozzle 52 on the fixed tube 51 to move along the direction of airbag movement and simultaneously complete the left and right reciprocating horizontal movement. This effectively expands the spray coverage of the foaming agent to a certain extent, while reducing the accumulation and dripping of the foaming agent on the surface of the airbag, ensuring the uniformity of the microbubble film layer. During the spraying of the foaming agent, the electric push rod 62 drives the clamping block 63 to move along the surface of the airbag so as to fully inspect the surface of the airbag in the area clamped and blocked by the clamping block 63, effectively reducing blind spots and improving the comprehensiveness and completeness of airbag inspection.
