Specific Embodiments

[0040] The core of the present utility model is to provide a monitoring device for the manufacturing quality of pultruded plates. This monitoring device for the manufacturing quality of pultruded plates can detect the straightness and internal defects of carbon fiber pultruded plates in real time online, improving the product quality and application reliability.

[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] Please refer to Figures 1 to 6 , Figure 1 which is an axonometric structural schematic diagram of the monitoring device for the manufacturing quality of pultruded plates provided by a specific embodiment of the present utility model; Figure 2 is Figure 1 the axonometric structural schematic diagram after rotation in Figure 3 is the front view of the monitoring device for the manufacturing quality of pultruded plates; Figure 4 is the axonometric structural schematic diagram of the second connecting block, vertical threaded rod and locking screw; Figure 5 is the left view of the monitoring device for the manufacturing quality of pultruded plates; Figure 6 is the schematic diagram of the control system composition of the monitoring device for the manufacturing quality of pultruded plates.

[0043] In a specific embodiment, the monitoring device for the manufacturing quality of pultruded plates provided by the present utility model includes a fixed limit plate 101 and a movable limit plate 103 installed on a workbench 1, a pushing mechanism 5 installed at the inlet end of the workbench 1 for pushing a mold to move between the fixed limit plate 101 and the movable limit plate 103, and a telescopic cylinder connected to the outside of the movable limit plate 103. In the initial state, the telescopic cylinder drives the movable limit plate 103 to move towards the side close to the fixed limit plate 101 so that the two side surfaces of the mold are respectively in close contact with the fixed limit plate 101 and the movable limit plate 103, and the telescopic rod of the telescopic cylinder can automatically expand and contract under the action of the mold; it also includes a straightness detection mechanism 3 for determining that the straightness of the mold is qualified when it detects that the force of the mold on the movable limit plate 103 is within a set pressure range.

[0044] In the above structure, the monitoring device for the manufacturing quality of pultruded plates includes a workbench 1, a fixed limit plate 101, a movable limit plate 103, a pushing mechanism 5, a telescopic cylinder and a straightness detection mechanism 3.

[0045] The fixed limit plate 101 and the movable limit plate 103 are installed on the workbench 1, and the fixed limit plate 101 and the movable limit plate 103 are used in combination. At least two telescopic cylinders are connected to the outside of the movable limit plate 103. Before the mold is placed, the telescopic rods of the telescopic cylinders retract, driving the movable limit plate 103 to move away from the fixed limit plate 101, and the distance between the fixed limit plate 101 and the movable limit plate 103 becomes larger. When the distance is greater than the width of the mold, the mold is placed between the fixed limit plate 101 and the movable limit plate 103 at the inlet. Then the telescopic rods of the telescopic cylinders extend, driving the movable limit plate 103 to move towards the fixed limit plate 101, so that the two side surfaces of the mold are respectively in contact with the fixed limit plate 101 and the movable limit plate 103, and the mold located at the inlet is clamped and positioned. The pushing mechanism 5 is installed at the inlet end of the workbench 1, and the pushing mechanism 5 pushes the mold to move towards the outlet between the fixed limit plate 101 and the movable limit plate 103.

[0046] During the process of the mold moving from the inlet to the outlet, the straightness of the mold generates a force on the movable limit plate 103, and the effect on the movable limit plate 103 is small at the inlet end and the outlet end, and the effect on the movable limit plate 103 is large at the middle position. The effect of the straightness of the mold on the movable limit plate 103 is mainly manifested as the magnitude of the force exerted by the mold on the movable limit plate 103, and further manifested as the displacement magnitude of the force driving the movable limit plate 103 to move away from the fixed limit plate 101. That is to say, the straightness of the mold can be reflected from the magnitude of the force exerted by the mold on the movable limit plate 103 and the displacement magnitude of the fixed limit plate 101.

[0047] The telescopic rod of the telescopic cylinder can automatically expand and contract under the action of the mold. When the straightness of the mold changes, the mold exerts a force on the movable limit plate 103, and the movable limit plate 103 transmits the received force to the straightness detection mechanism 3, and compares the received force information with the set pressure range. When it is detected that the force exerted by the mold on the movable limit plate 103 is within the set pressure range, it is judged that the straightness of the mold is qualified; when it is detected that the force exerted by the mold on the movable limit plate 103 is not within the set pressure range, it is judged that the straightness of the mold changes too much and is unqualified, so as to realize the real-time monitoring of the straightness of the product.

[0048] The monitoring device for the manufacturing quality of the pultruded plate provided by the present utility model realizes the real-time monitoring of the straightness of the product through the straightness detection mechanism 3, and then conducts real-time online detection of the product through the data at the output end, thereby replacing the original method of manually monitoring the product quality irregularly, and improving the manufacturing quality and reliability of the product.

[0049] On the basis of the above various specific embodiments, the straightness detection mechanism 3 includes:

[0050] A pressure sensor 309 for detecting the acting force of the mold on the inner side surface of the movable limit plate 103;

[0051] A first detection unit connected to the pressure sensor 309 for determining that the straightness of the mold is qualified when the pressure value detected by the pressure sensor 309 is within a set pressure range.

[0052] In practical applications, the straightness detection mechanism 3 may include a pressure sensor 309 and a first detection unit. The pressure sensor 309 detects the acting force of the mold on the inner side surface of the movable limit plate 103 and sends it to the first detection unit. The first detection unit compares the received pressure value with the set pressure range. When the pressure value detected by the pressure sensor 309 is within the set pressure range, it is determined that the straightness of the mold is qualified. When the pressure value detected by the pressure sensor 309 is not within the set pressure range, it is determined that the straightness of the mold is unqualified. This detection method can be achieved with one pressure sensor 309. It is judged by the pressure detected by one pressure sensor 309, and the structure is simple and easy to implement.

[0053] Based on the above specific embodiments, the straightness detection mechanism 3 includes:

[0054] A plurality of pressure sensors 309 arranged at intervals in the length direction of the movable limit plate 103;

[0055] A second detection unit connected to the pressure sensor 309 for determining that the straightness of the mold is unqualified when more than three-quarters of the pressure values detected by the plurality of pressure sensors 309 are not within the set pressure range.

[0056] In practical applications, the straightness detection mechanism 3 may include a plurality of pressure sensors 309 and a second detection unit. The plurality of pressure sensors 309 are spaced apart and distributed in the entire length direction of the movable limit plate 103. The plurality of pressure sensors 309 simultaneously detect the magnitude of the acting force of the mold on the movable limit plate 103 when the mold moves to different positions. When more than three-quarters of the pressure values detected by the plurality of pressure sensors 309 are not within the set pressure range, it indicates that the values detected by the pressure sensors 309 are accurate and the detection errors are excluded. During detection, more accurate values can be obtained through data comparison of the plurality of pressure sensors 309, and the change trend of the straightness of the mold can be inferred. Even if there is a malfunction in an individual pressure sensor 309, it will not affect the detection result, ensuring real-time online monitoring of the straightness.

[0057] On the basis of the above specific embodiments, the second detection unit may include a theoretical drawing module, an actual drawing module, and an image judgment module. The theoretical drawing module is used to draw a minimum pressure straight line, a maximum pressure straight line, and a zero pressure straight line according to the set pressure range; the actual drawing module is used to draw a pressure curve graph according to the pressure values detected by a plurality of pressure sensors 309; the image judgment module is used to judge that the straightness of the mold is qualified when the pressure curve graph is between the minimum pressure straight line and the maximum pressure straight line. By directly viewing the positional relationship between the pressure curve graph and the theoretical drawing module and the actual drawing module in the figure, the comparison result is more intuitive and vivid, which is conducive to the understanding and analysis of the staff.

[0058] On the basis of the above specific embodiments, the image judgment module may include a ranging member and a position acquisition member. The ranging member is used to measure the distances between the wave peaks and wave valleys on the pressure curve graph and the zero pressure straight line; the position acquisition member is connected to the ranging member and is used to obtain the position where the maximum distance is located according to the distances between the wave peaks and wave valleys on the pressure curve graph and the zero pressure straight line. Since the straightness of the mold changes the most at the wave peaks and wave valleys, by comparing the distances between the wave peaks and wave valleys and the zero pressure straight line, the position of the wave peak or wave valley with the maximum distance is found, so as to improve the forming parameters of the pultruded board at this position, strengthen the control of the straightness of the pultruded board at this position during the production process, and improve the overall straightness of the mold.

[0059] On the basis of the above specific embodiments, it further includes a movement control mechanism capable of controlling the vertical position, horizontal position, and longitudinal position of the pressure sensor 309. The movement control mechanism is used to control the position of the pressure sensor 309 to coincide with the position to be detected on the mold.

[0060] In practical applications, by adjusting the vertical position, horizontal position, and longitudinal position of the pressure sensor 309 through the movement control mechanism, changing the vertical movement, horizontal movement, and longitudinal movement of the pressure sensor 309, that is, the detection position of the pressure sensor 309 is adjustable, ensuring that the pressure sensor 309 is consistent with the position to be detected on the mold. It not only realizes the detection of different positions of the same mold, but also can realize the detection of molds with different heights and the detection of molds with different widths. It is convenient to use and has a wide application range.

[0061] On the basis of the above specific embodiments, the movement control mechanism includes a vertical guide rod 301 installed on the workbench 1, a connecting block connected to the vertical guide rod 301, a vertical threaded rod 304 threadedly connected to the vertical threaded hole of the connecting block, and a locking screw 305 for locking the connecting block and the vertical threaded rod 304;

[0062] There are at least two groups of vertical threaded rods 304 and locking screws 305 on the connecting block, and the number of vertical guide rods 301 is at least two.

[0063] In a specific embodiment, the workbench 1 is placed on the ground, and a movement control mechanism is installed on the workbench 1.

[0064] Among them, the movement control mechanism is composed of a vertical guide rod 301, a first connection block 302, a second connection block 303, a vertical threaded rod 304, and a locking screw 305. Two vertical guide rods 301 are welded to the top surface of the workbench 1. A first connection block 302 slides on the two vertical guide rods 301. Two second connection blocks 303 with a hexagonal structure slide inside the first connection block 302. The second connection block 303 is equivalent to a height supplement of the first connection block 302, increasing the height of the connection block while ensuring that the connection block is lighter in weight, meeting the vertical adjustment range. A vertical threaded rod 304 is threadedly connected to each second connection block 303, and two locking screws 305 are threadedly connected to the first connection block 302. The two locking screws 305 are used to fix the two vertical threaded rods 304 on the first connection block 302.

[0065] The number of the vertical threaded rods 304 and the locking screws 305 is two sets. When adjusting the height of the pressure sensor 309, loosen the left locking screw 305 and the right locking screw 305, and rotate the vertical threaded rod 304 to adjust the height of the vertical threaded rod 304. Under the threaded drive of the vertical threaded rod 304, the height adjustment of the first connection block 302 can be realized, and thus the height adjustment of the pressure sensor 309 can be realized. After the height is adjusted, loosen the left locking screw 305 or / and the right locking screw 305 to fix the height of the pressure sensor 309.

[0066] In contrast to the existing device, the above embodiment can realize the adjustment of the pressure sensor 309, and when one of the vertical threaded rods 304 for adjustment is damaged, emergency adjustment can be carried out through other vertical threaded rods 304, that is, the height of the pressure sensor 309 can be adjusted by at least one vertical threaded rod 304. The present application provides at least two vertical threaded rods 304 as spares to prevent the damage of one vertical threaded rod 304 from affecting the normal operation.

[0067] On the basis of the above various specific embodiments, the movement control mechanism further includes a longitudinal guide rod 306 connected longitudinally to the connection block, a mounting block 310 connected to one end of the longitudinal guide rod 306 close to the movable limit plate 103, and a longitudinal threaded rod 307 threadedly connected to the longitudinal threaded hole of the connection block. The end of the longitudinal threaded rod 307 abuts against the mounting block 310, and the pressure sensor 309 is connected to the mounting block 310.

[0068] In a specific embodiment, two longitudinal guide rods 306 slide on the first connecting block 302. One end of the front sides of the two longitudinal guide rods 306 is welded to the mounting block 310, and a pressure sensor 309 is mounted on the front end face of the mounting block 310. A longitudinal threaded rod 307 is threadedly connected to the first connecting block 302. One end of the front side of the longitudinal threaded rod 307 rotates on the rear end face of the mounting block 310. When adjusting the front and rear positions of the pressure sensor 309, just rotate the longitudinal threaded rod 307. Driven by the longitudinal threaded rod 307, the mounting block 310 and the pressure sensor 309 complete the adjustment of the front and rear positions.

[0069] Wherein, a spring 308 is sleeved on the longitudinal threaded rod 307. One end of the front side of the spring 308 is elastically in contact with the rear end face of the first connecting block 302, and one end of the rear side of the spring 308 is elastically in contact with the front end face of the handle on the longitudinal threaded rod 307. Under the elastic pressing action of the spring 308, the longitudinal threaded rod 307 can be prevented from loosening, ensuring the detection accuracy.

[0070] Based on the above various specific embodiments, the mounting block 310 is attached to the outer side face of the movable limiting plate 103. The movable limiting plate 103 is a silica gel plate. The texture of the silica gel plate is relatively soft. The acting force of the mold on the silica gel plate is better transmitted to the acting force of the silica gel plate on the pressure sensor 309. The silica gel plate can more accurately reflect the change in the straightness of the mold. The pressure sensor 309 in contact with the silica gel plate can obtain a more accurate value during detection.

[0071] Wherein, a fixed limiting plate 101 is welded to the top end face of the workbench 1. Two first electric cylinders 102 are fixed on the top end face of the workbench 1. The extending ends of the two first electric cylinders 102 are fixed to the rear end face of the movable limiting plate 103. The movable limiting plate 103 is located directly behind the fixed limiting plate 101.

[0072] Based on the above various specific embodiments, the height of the mounting block 310 and the mold is less than the height of the movable limiting plate 103. The height of the movable limiting plate 103 is relatively large, which can adapt to molds of different sizes. The height of the mounting block 310 is equal to the range to be detected of the mold. The height of the mounting block 310 can be less than the height of the mold. Under the condition of meeting the detection requirements, the weight of the mounting block 310 is reduced, and it is more convenient for the movement control mechanism to drive the mounting block 310 to move.

[0073] Based on the above various specific embodiments, it further includes a non-destructive testing on-line monitor 202 disposed above the outlet of the workbench 1. The non-destructive testing on-line monitor 202, namely the NDT on-line monitor, is a device that uses various NDT technologies to perform real-time and continuous detection on materials or molds to ensure their quality and safety. Among them, a first detection part 2 is installed on the workbench 1. The first detection part 2 is composed of a mounting frame 201 and a non-destructive testing on-line monitor 202. A concave-structured mounting frame 201 is fixed on the top surface of the workbench 1, and a non-destructive testing on-line monitor 202 is fixed on the top surface of the inner wall of the mounting frame 201.

[0074] In this application, the non-destructive testing on-line monitor 202 can be a phased array flaw detection system. Using phased array ultrasonic technology, it can detect large panels and components as well as inaccessible areas; it can also be ultrasonic testing, using ultrasonic probes to detect tiny defects in materials. The non-destructive testing on-line monitor 202 improves the detection efficiency and accuracy through automation and real-time data analysis, which helps to promptly discover and handle potential quality problems or safety hazards.

[0075] Based on the above various specific embodiments, it further includes a control box 4 disposed on the workbench 1. A microprocessor 401 and a communication module 402 are installed in the control box 4. The microprocessor 401 and the communication module 402 are electrically connected. The microprocessor 401 is electrically connected to the telescopic cylinder, the non-destructive testing on-line monitor 202, the straightness detection mechanism 3, and the pushing mechanism 5.

[0076] In practical applications, a control box 4 is fixed on the top surface of the workbench 1. A microprocessor 401 and a communication module 402 are installed in the control box 4. The microprocessor 401 and the communication module 402 are electrically connected. The microprocessor 401 is electrically connected to the first electric cylinder 102, the non-destructive testing on-line monitor 202, the pressure sensor 309, and the second electric cylinder 502.

[0077] During the use process, the staff operates the mobile terminal to send signals to the microprocessor 401 through the communication module 402. The microprocessor 401 can control the first electric cylinder, the non-destructive testing on-line monitor 202, the pressure sensor 309, and the second electric cylinder to work. Similarly, the non-destructive testing on-line monitor 202 and the pressure sensor 309 can transmit the detection data to the microprocessor 401, and the microprocessor 401 sends the detection data to the mobile terminal through the communication module 402.

[0078] When the mold is pushed, control the second electric cylinder 502 to extend. At this time, the push plate 503 pushes the mold to the left. When the mold contacts the pressure sensor 309, it is detected by the pressure sensor 309. When the mold moves below the non-destructive testing on-line monitor 202, the non-destructive testing on-line monitor 202 can complete the re-detection. When adjusting the height of the pressure sensor 309, rotate the vertical threaded rod 304. Driven by the thread of the vertical threaded rod 304, the height adjustment of the first connecting block 302 can be realized, that is, the height adjustment of the pressure sensor 309 is realized. When adjusting the front and rear positions of the pressure sensor 309, just rotate the longitudinal threaded rod 307. Driven by the longitudinal threaded rod 307, the mounting block 310 and the pressure sensor 309 complete the adjustment of the front and rear positions.

[0079] Among them, the communication module 402 can be a 4G module, which is a hardware module integrating 4G wireless communication technology and is widely used in the fields of Internet of Things, smart home, vehicle networking, remote monitoring, etc. It realizes the functions of Internet and mobile communication by accessing the mobile network and supports high-speed data transmission. The 4G module uses orthogonal frequency division multiplexing modulation technology and adopts the long-term evolution protocol for communication to achieve fast and reliable data transmission.

[0080] Among them, a pushing mechanism 5 is installed on the right side of the workbench 1. The pushing mechanism 5 is composed of a mounting seat 501, a second electric cylinder 502 and a push plate 503.
