Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite material testing technology, specifically to an online inkjet printer for non-destructive testing of pultruded plates. Background Technology
[0002] In the manufacturing process of pultruded glass sheets, pultruded carbon sheets, and other workpieces, online pultrusion molding and automatic winding and packaging necessitate online inspection of the pultruded sheets. The online inspection equipment is integrated between the traction unit and the cutting unit of the pultruded sheet production line. Currently, to ensure product quality, the corresponding inspections are divided into two types: external defect inspection and internal defect inspection. Internal defect inspection generally employs ultrasonic testing (UT) within Non-Destructive Testing (NDT).
[0003] For example, Chinese invention publication CN116539715A, dated August 4, 2023, discloses an online automatic phased array inspection device for detecting internal defects in carbon fiber, glass fiber, or carbon-glass hybrid plate workpieces during horizontal linear movement. The device includes: a support structure that provides horizontal support to the moving workpiece within a set range; a water immersion device that, within a set range, immerses the inspection area—comprising the width of at least one side of the workpiece surface and a set length range—within a set range; and an ultrasonic phased array water immersion probe that is immersed in the liquid to perform non-destructive testing on the workpiece. The detection range of the ultrasonic phased array water immersion probe covers the inspection area. This invention enables automatic detection of internal defects during the online pultrusion process of carbon fiber, glass fiber, or carbon-glass hybrid plates, effectively solving the efficiency problems and instability issues of manual inspection.
[0004] As can be seen from the above patents, the detection device requires the relative positional relationship between the metering device, the detection structure, and the ultrasonic phased array immersion probe to confirm the position of the detected location along the length of the workpiece. In particular, the calculation and confirmation process of the defect location is quite cumbersome. Therefore, this invention provides an online inkjet-printed pultruded plate non-destructive testing instrument to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an online inkjet printing non-destructive testing instrument for pultruded plates.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A non-destructive testing instrument for pultruded plates with online inkjet printing includes a support platform 1. A pultruded plate conveyor belt 2 is disposed on the top of the support platform 1, and pultruded plates 3 are conveyed onto the pultruded plate conveyor belt 2 and conveyed forward along the pultruded plate conveyor belt 2. A flaw detection system 4 is disposed above the pultruded plate 3. The flaw detection system 4 includes an electric slide plate 41, which is slidably fitted in a slide rail 5. The slide rail 5 is fixedly connected to the support platform 1 by a fixed bracket. Several probes 42 are evenly distributed at equal intervals on the electric slide plate 41 facing the pultruded plate 3. The outer circumference of each probe 42 is covered by a nozzle 43, which is fitted outside the probe 42.
[0008] Preferably, a control cabinet 6 is provided on one side of the support platform 1. The control cabinet 6 contains a control system 7, an ultrasonic system 8, and a coding system 9 arranged sequentially from top to bottom and separated by partitions. The control system 7 is electrically connected to the electric slide plate 41, the ultrasonic system 8, and the coding system 9, respectively.
[0009] Preferably, the pultruded plate conveyor belt 2 includes a drive motor 21, which is disposed at the bottom of the support platform 1. The drive motor is electrically connected to the control system 7. An active roller 22 and a driven roller 23 are disposed above the drive motor 21. The output shaft of the drive motor 21 is connected to the central shaft of the active roller 22 via a belt. The driven roller 23 is connected to the active roller 22 via a conveyor belt 24.
[0010] Preferably, a probe wire 44 and a nozzle connection wire 45 are respectively provided inside the electric slide plate 41 near the probe 42. The ultrasonic system 8 is electrically connected to the probe 42 through the probe wire 44, and the inkjet printing system 9 is connected to the nozzle 43 through the nozzle connection wire 45.
[0011] Preferably, the distance between the edge of the electric sliding plate 41 and the edge of the probe 42 is not less than twice the distance between adjacent probes 42.
[0012] Preferably, the electric sliding plate 41 slides in the slide rail 5 with an amplitude equal to the distance between the probes 42.
[0013] The beneficial effects of this utility model are:
[0014] An electric sliding plate is mounted on a slide rail. Several evenly spaced probes are installed on the electric sliding plate, and a nozzle is fitted over the probes. The sliding of the electric sliding plate causes the probes to perform flaw detection on the surface of the pultruded sheet. The location of defects is fed back from the flaw detection system to the control system, which then sends a command to the inkjet printing system for online inkjet printing. This invention solves the problem of the cumbersome process of calculating and confirming defect locations, enabling real-time online detection of the pultruded sheet quality, automatic transmission of detection data, and online inkjet printing of defect locations, achieving real-time online automated detection and defect marking throughout the entire pultrusion process.
