Technical Field

[0002] FRP pipe is also called glass fiber wound sand-filled pipe, which is mainly composed of anti-corrosion layer, anti-seepage layer, structural layer and outer protective layer. The structural layer is based on resin with excellent mechanical strength, and the reinforcing materials are circumferentially wound fibers, E-type chopped fibers and selected quartz sand that enhance the reversing tensile strength, axial tensile strength and external load. When the resin, glass fiber pipe and quartz sand are combined, the glass fiber impregnation degree needs to be tested. Glass fiber impregnation is one of the key indicators in the production process of FRP pipes. Its quality and stability are directly related to the quality level and quality consistency of FRP pipes. FRP pipe processing requires full impregnation between resin, glass fiber and quartz sand to ensure good interface bonding between materials, reduce or even eliminate the occurrence of internal defects in the substrate such as substrate voids and resin voids caused by poor impregnation; At present, the detection of wetness in the process of producing FRP pipes is carried out manually with the naked eye. This method completely relies on the experience of the inspectors to judge, resulting in low accuracy of the test results and inability to perform continuous testing. At the same time, there are devices on the market that can realize intelligent detection of glass wetness. When completing installation activities, the overall adjustability is low, that is, the combined adjustability of the shooting angle and height is poor, so that the position adjustment is generally required by moving the sand discharge mechanism, which affects the convenience and accuracy of the angle or position adjustment, resulting in a certain impact on the subsequent assembly wetness detection effect.

DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0022] See also Figure 1-5 The present invention provides a method for detecting the impregnation degree of glass fiber, comprising the following steps: S100, installing the detection mechanism to the outside of the sand discharge mechanism through the multifunctional adjustment device 8 provided inside the mounting frame 2; The detection mechanism can be installed on the side of the sand discharge mechanism through the multifunctional adjustment device 8 provided inside the mounting frame 2, so as to realize the rapid installation and use of the entire detection mechanism; S200, through the setting of the multifunctional adjustment device 8, the conversion transmission structure 81, the lifting component 82, the angle adjustment component 83, the connecting bar 84 and the vibration reduction component 85 provided inside can be coordinated to realize the flexible adjustment of the height and angle used by the detection mechanism, so as to ensure the clear shooting and recording comparison of the subsequent detection images; S300, the detection mechanism captures the target area image of the pipeline 7 through the internal camera 4, and transmits the image information to the external encoder to form a detection image: S301, connecting the camera 4 to the external encoder through the external interface to realize the electrical connection between the camera 4 and the encoder, so that the camera 4 accurately matches the position information and image size of the 7-line scanning direction of the pipeline through the frequency division and backup frequency of the encoder signal and the pulse signal of the connecting spindle servo motor; Specifically, in step S301, the camera 4 can be an industrial linear array camera, and the installation height of the camera 4 can be flexibly adjusted through the multifunctional adjustment device 8. For example, the installation height of the camera 4 is adjusted to about 800 mm, the acquisition width is fixed to 800 mm, and the acquisition frequency is adjustable in the range of 30S-5min. In this way, when the pipeline 7 rotates with the main shaft of the servo motor, the camera 4 can cooperate with the external encoder to realize the shooting and acquisition of the detection image; Specifically, the camera 4 is used to capture and collect the grayscale image of the long target area. At the same time, the acquired image information can be transmitted to the external encoder to convert the captured detection image into a grayscale image. At the same time, the white pixel values ​​inside the grayscale image are acquired. Thus, the white pixel values ​​inside the grayscale image can be used for comparison and judgment activities.

[0023] S302, before collecting the target image, the fill lights 5 provided on both sides of the lower end of the light shield 3 need to be turned on, so that the fill lights 5 on both sides can complement each other, thereby improving the image capture clarity: Specifically, the fill light 5 is relatively arranged on the left and right sides of the lower end of the light shield 3, and the fill light center point of the fill light 5 on both sides and the image acquisition center point of the camera 4 form an angle of 13.62°; Specifically, the fill lights 5 installed opposite to each other on the left and right can provide fill light coordination in a fan-shaped area, and the fill light center points of the fill lights 5 on both sides intersect with the collection center point of the camera 4 at an endpoint. In this way, the fill lights 5 on both sides can realize auxiliary fill light activities for image shooting and collection by the camera 4 to ensure that the collected image is clear and not blurred. In addition, the fill lights 5 use LED lamps, which can achieve environmentally friendly and long-life fill light coordination.

[0024] S303, the exhaust pipe 6 installed on one side of the outer end of the light shield 3 can suck out the dust attached to the collection area to prevent dust from attaching and affecting the clarity of the image shooting of the target area: Specifically, by arranging the exhaust pipe 6 at one side of the outer end of the light shield 3, the bottom open end of the light shield 3 can have a certain dust absorption effect; That is, the exhaust pipe 6 can be connected to the external negative pressure device, so that when the external negative pressure device is running, the exhaust pipe 6 can suck out the dust attached to the outside of the pipe 7, thereby reducing the blurring of the collected target area image due to the influence of dust, thereby realizing the formation of a good collection and detection environment and ensuring the clear collection and shooting of the target area image; S400, the white pixel value inside the obtained detection image can be compared with the contrast threshold set by the device to determine whether the white pixel value is within the threshold range and whether the overall wetness of the glass fiber is qualified. Please refer to Figure 3 , including the following steps: S401, the collected target image is in grayscale, that is, displayed as a black and white image; Specifically, under the shooting and collection of the camera 4, the image of the target area outside the pipeline 7 can be quickly captured, and the white area of ​​the area image can be calculated with the external software; S402, using the camera 4 to obtain the white prime ratio of the captured image; Specifically, the proportion of off-white pigments is set according to actual production. For example, a better proportion of off-white pigments is explored in actual production as the initial threshold. If different types of FRP pipes are produced, the initial threshold should be adjusted according to the actual production situation. S403, measuring and acquiring the displayed white pixel value of the collected grayscale image, and comparing it with the set ratio, and automatically understanding the glass fiber impregnation quality by comparing the data; S404, that is, when the white pixel value of the collected grayscale image is lower than the measurement setting ratio, it means that the wetness measurement is qualified, and OK is displayed on the camera 4; if it is higher than the measurement setting ratio, it means that the wetness measurement is unqualified, and NG is displayed on the camera 4. After the NG situation is displayed, corresponding adjustments are made in time; Specifically, a pixel statistical algorithm is used to calculate the ratio of the number of pixels with a grayscale range of 100-256, for example, that are set to be white in the detection area to the total number of pixels, and an alarm signal is given according to a set upper limit ratio, for example, 8%; See also Figure 3That is, through steps 402 and 403, the proportion of white pixels in the collected grayscale image is quickly obtained, and the proportion of white pixels is compared with the set qualified proportion. For example, the initial comparison threshold in step 402 can be set to 8%. When the proportion of white pixel values ​​in the collected image is lower than the threshold of 8%, it means that the glass fiber infiltration is qualified and meets the infiltration standard, and there is no need to adjust the sand output and resin amount. If the proportion of white pixel values ​​in the collected image is higher than the threshold of 8%, it means that the glass fiber infiltration is unqualified and does not meet the infiltration standard. At this time, the external alarm device will be triggered to remind the staff, and the staff can arbitrarily extract the images taken during the alarm period. The captured regional images can be used to accurately understand the unqualified positions of the glass fiber tube impregnation degree. Then, the material flow rate of the unqualified positions can be analyzed to adjust the quartz sand output or the resin amount accordingly, so that the glass fiber tube impregnation degree can meet the production standards again. Among them, the camera 4 is connected to the NB500 intelligent recognition software on the industrial computer, and the images collected by the camera 4 can be displayed in the software. The NB500 software can judge whether it is lower than the lower limit of the white pigment value based on the collected images, and connect the external input and output board through the USB port. When it is judged to be unqualified, the switch signal of the output point of the board is used to control the alarm light to remind the operator to deal with the unqualified glass fiber impregnation situation in time. Secondly, when the equipment is just turned on and the resin and fiber tube are combined, it is more susceptible to the influence of the amount of sand and the amount of resin, resulting in the impregnation degree detected just after the machine is started up being more likely to be unqualified. Therefore, when the machine is just turned on, it is necessary to pay attention to the regional image taken by the camera 4 in real time, and flexibly adjust the amount of sand and the amount of resin according to the regional image, so that the impregnation degree of the glass fiber tube can continue to maintain the standard qualified state during the subsequent stable processing; The above steps are the complete steps for testing the wettability of glass fibers.

When shooting and collecting the glass fiber of the pipeline 7, the camera 4 installed at the upper end of the light shield 3 can be turned on to realize image shooting and collection. At the same time, in order to ensure the clarity of the captured image, the fill light 5 installed on both sides of the lower end of the light shield 3 can be turned on to realize fill light coordination to ensure the clarity of image collection. At the same time, in the collection process, in order to avoid dust adhesion on the outside of the pipeline 7, an exhaust duct 6 is installed on one side of the outer end of the light shield 3, so that the exhaust duct 6 is connected to the external negative pressure equipment, so that when the negative pressure equipment is running, the dust can be sucked out from the exhaust duct 6 to ensure that the outside of the pipeline 7 is clean and tidy, and the captured image is clear.

In this way, the threaded tube 824 connected to the middle of the driven wheel 823 will rotate accordingly to carry out the threaded lifting transmission effect with the first screw rod 825 connected to the middle. As the threaded tube 824 moves up and down, the connecting frame 826 connected to the outer side of the threaded tube 824 can realize the overall up and down lifting adjustment support and coordination of the mounting frame 2 along the inside of the mounting plate 827, so that the lifting height adjustment process of the detection mechanism is stable and fast, and then, the flexible adjustment of the use height of the detection mechanism can be achieved and the requirements of different infiltration detection heights can be met. If it is necessary to adjust the use angle of the camera 4 inside the detection mechanism, the rotating shaft 813 can be pushed down to make the connecting plate 8141 originally in the first chuck 816 move downward. At the same time, the balls 8144 installed at the four side mounting grooves 8142 inside the connecting plate 8141 will move out of the slots 8161 opened on the four sides of the first chuck 816 to quickly release the lifting and lowering adjustment driving state. At this time, the moving connecting plate 8141 will enter the interior of the mounting tube 815. During the entry process, the balls 8144 on the four sides will move out of the slots 8161 opened on the four sides of the first chuck 816. The smooth inner concave portion at the upper end of the mounting tube 815 blocks and squeezes, and automatically moves into the corresponding mounting groove 8142, and squeezes the compression spring 8143 connected to the outside, so that the four-side ball bearings 8144 will be in a state of simultaneous compression of the outer top, and when the shaft 813 moves the connecting disk 8141 downward, the connecting disk 8141 will be clamped into the second chuck 817 installed at the upper end of the first bevel gear 831, and at the same time, the compression springs 8143 compressed at the four-side mounting grooves 8142 inside the connecting disk 8141 will use the rebound effect to push the ball bearings 8144 into the corresponding mounting groove 8142. 8144 is quickly ejected, so that the four balls 8144 are engaged with the slots 8161 opened on the four sides of the second chuck 817, so as to achieve the combination of the second chuck 817 and the connecting disk 8141, that is, to achieve the formation of the angle adjustment state. At this time, when the shooting angle of the detection mechanism is to be adjusted, the rotating shaft 813 can be rotated to achieve the synchronous rotation of the connected connecting disk 8141 and the second chuck 817, thereby, the first bevel gear 831 will rotate accordingly to mesh with the second bevel gear 832 connected to the bottom of the transmission, so that the first bevel gear 831 is connected to the second bevel gear 832. The second screw rod 833 in the middle of the second bevel gear 832 will rotate accordingly to thread the push-pull bar 834, so as to realize the leftward movement of the push-pull bar 834 as a whole. When the push-pull bar 834 moves leftward, the connecting bar 84 connected to the left side of the push-pull bar 834 will be pushed leftward by the push-pull bar 834 to assist in clockwise swinging. As a result, the light shield 3 connected to the outer side of the connecting bar 84 will be swung and adjusted accordingly. In this way, the shooting and collection angle of the camera 4 arranged at the upper end of the light shield 3 can be flexibly adjusted to meet the shooting and collection requirements of different glass fiber infiltration degrees. Furthermore, as the rotating shaft 813 drives the docking piece 814 to move up and down, the docking piece 814 can be flexibly connected and combined with the first chuck 816 or the second chuck 817, thereby satisfying the flexible conversion between the lifting and lowering adjustment state and the angle adjustment state, and quickly and conveniently meeting the different shooting and collection requirements of the detection mechanism.

[0031] Please refer to 10-11. The vibration reduction assembly 85 in this embodiment includes a first clamping member 851 installed on the left inner side of the upper end of the mounting frame 2, and a second clamping member 852 is installed on the inner bottom of the left inner side of the upper end of the mounting frame 2. The first clamping member 851 and the second clamping member 852 are respectively connected to the upper and lower sides of the connecting strip 84. The first clamping member 851 includes a first connecting plate 8511 with a vertical hollow groove connected to the upper end of the push-pull strip 834, and a swing arm 8512 connected to the upper end of the first connecting plate 8511. The lower end of the swing arm 8512 is not only connected to the vertical hollow groove inside the first connecting plate 8511, but also the middle part of the swing arm 8512 will be rotatably connected to the inside of the mounting frame 2, connected to the second connecting plate 8513 at the upper end of the swing arm 8512, and the second connecting plate 8513 and the first connecting plate 8511 are integrally structured. The second connecting plate 8513 is consistent with the first connecting plate 8511, but the second connecting plate 8513 is installed in the opposite state to the first connecting plate 8511. The moving bar 8514 is laterally fastened to the upper end of the second connecting plate 8513, and the guide rod 8515 is laterally inserted into the inside of the moving bar 8514 and fixedly connected to one side of the inner upper end of the mounting frame 2. The guide rod 8515 is laterally supported, so that the moving bar 8514 can be stably pushed and pulled in the horizontal direction. The support rod 8516 vertically installed inside the left side of the moving bar 8514 is movably connected to the outer side of the lower end of the support rod 8516, and the pressure block 8517 that can be extended and retracted up and down is movably connected, and the bottom of the pressure block 8517 is against the upper end of the connecting strip 84, and a connecting rod is integrally penetrated in the middle of the lower end of the pressure block 8517. Secondly, the front and rear ends of the connecting rod provided in the middle of the lower end of the pressure block 8517 will be slidably inserted into the groove on the inner wall of the mounting frame 2 (such as Figure 7 As shown in FIG. 85 ), a first spring 8518 mounted on the outside of the support rod 8516 can provide elastic downward pressure support.

[0032] Among them, the second clamping member 852 includes a connecting seat 8521 that is fastened to the inner bottom of the left side of the upper end of the mounting frame 2, dampers 8522 symmetrically installed on the left and right sides of the connecting seat 8521, a support tube 8523 that is fastened to the middle of the connecting seat 8521, a plug-in shaft 8524 that is vertically movably plugged into the support tube 8523, a second spring 8525 installed on the outside of the plug-in shaft 8524, a stop block 8526 that is docked to the outside of the upper end of the plug-in shaft 8524 and embedded in the connecting seat 8521, and the top of the stop block 8526 is a smooth round convex shape, and the upper ends of both sides of the inside of the stop block 8526 are connected to the tops of the dampers 8522 arranged on both sides.

[0033] When the connecting bar 84 is pushed by the push-pull bar 834 and performs a clockwise swinging activity, in order to ensure that the swinging process of the connecting bar 84 is stable and the swinging jitter problem is reduced, the sunshade 3 after the angle adjustment is not prone to shaking for a long time. For this reason, a vibration reduction component 85 is installed on the upper and lower sides of the connecting bar 84 and the upper end of the push-pull bar 834. That is, when the push-pull bar 834 moves to the left, it can synchronously drive the connected first connecting plate 8511 to move to the left. As the first connecting plate 8511 moves to the left, the swing arm 8512, which is connected to the vertical hollow inside the first connecting plate 8511 and is rotatably connected to the upper end of the mounting frame 2, will swing clockwise accordingly. As a result, the second connecting plate 8513 connected to the upper end of the swing arm 8512 can drive the moving bar 8514 to move right, and the guide plate 8513 connected to the middle of the right side of the moving bar 8514 Rod 8515 can be used for lateral movement support and guidance, and the pressure block 8517 docked on the left side of the moving bar 8514 will move rightward and shrink with the moving bar 8514 and the connecting rod inserted at the bottom and the internal sliding combination of the upper end of the mounting frame 2, so as to ensure that after the connecting bar 84 swings clockwise, the pressure block 8517 can automatically adjust the length of the device to ensure that the clockwise swing adjustment of the connecting bar 84 is smooth and not stuck without changing the clamping and stabilizing effect, and when the pressure block 8517 moves up and is collected to the left side of the moving bar 8514, it will move up vertically and stably along the support rod 8516 provided on the left side of the moving bar 8514. At the same time, the first spring 8518 provided on the outer side of the support rod 8516 can strengthen the pressing effect of the pressure block 8517 against the outer side of the upper end of the connecting bar 84. Secondly, when the connecting strip 84 swings clockwise, the block 8526 that abuts against the bottom of the connecting strip 84 will release the squeezing effect, so that the plug-in shaft 8524 arranged at the upper end of the block 8526 can automatically move up and support through the rebound assistance of the second spring 8525 stretched externally. In this way, when the connecting strip 84 swings clockwise, the block 8526 can automatically adapt and move out to abut against each other, thereby achieving stable support at the bottom. At the same time, with the telescopic cooperation of the dampers 8522 arranged on both sides of the connecting seat 8521, the automatic top state of the block 8526 can be stabilized, which can reduce The elastic shaking problem is solved. Therefore, when the connecting strip 84 is pushed by the push-pull strip 834 to adjust the shooting and collecting angle of the detection mechanism, the pressure block 8517 against the upper end can adjust the position and length with the swinging movement, but does not change the clamping and anti-sway supporting effect at the top. At the same time, the resistance block 8526 against the bottom can realize automatic ejection supporting activity. Therefore, the pressure block 8517 and the resistance block 8526 are combined with each other up and down to achieve the stability of the clockwise swinging adjustment process of the connecting strip 84, reduce the adjustment shaking effect, and improve the efficiency of the detection mechanism to be quickly put into use.
