specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 4 Describe this embodiment, this embodiment includes a first bracket 1, a first guide roller 2, a second guide roller 3, a support plate 4, a third guide roller 5, a fourth guide roller 6, a reflection plate 7, and a probe support frame 8 , probe 9, near-infrared spectrometer 10, computer 11, data transmission line 12, optical fiber 13 and the second support 15, near-infrared spectrometer 10 and computer 11 are respectively arranged on the upper end face of the second support 15, near-infrared spectrometer 10 and computer 11 Connected by the data transmission line 12, the first bracket 1 and the second bracket 15 are arranged longitudinally sequentially, the first guide roller 2 and the second guide roller 3 are vertically fixed on the upper end surface of the first bracket 1 respectively, and the third guide roller 5 is opposite to each other. The second guide roller 3 is vertically arranged, and one end of t...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 with figure 2 The present embodiment will be described. The probe 9 of the present embodiment has a diameter of 6 mm. Since the width of the prepreg tape 14 to be tested is only a few millimeters, this design enables the probe 9 to collect the information of the prepreg tape 14 to be tested. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 with figure 2 To illustrate this embodiment, the distance t1 between the head of the probe 9 and the prepreg tape 14 to be tested is 1 mm, and the distance t2 from the end surface of the reflector 7 opposite to the probe 9 to the prepreg tape 14 to be tested is 1 mm. This design ensures that the collection of information is collected in a non-contact state, and the prepreg tape 14 to be tested is not damaged. Other components and connections are the same as those in the first embodiment.

Abstract

The invention discloses an online device for rapidly detecting the quality indicators of a prepreg tape, and relates to a device for detecting the quality indicators of the prepreg tape. The invention is to solve the problem of time-consuming, energy-consuming and large reagent-consuming nature of the analysis results in the existing prepreg tape detection method. A first guide roll and a second guide roll are respectively fixed on a first bracket in a vertical manner; a third guide roll and the second guide roll are arranged vertically and fixedly connected with a support plate which is vertically fixed on the first bracket, a fourth guide roll and the third guide roll are arranged in a top and bottom staggered manner, a probe is arranged at one side of the prepreg tape to be tested, thehead part of the probe is opposite to the prepreg tape to be tested, a reflecting plate is arranged at the other side of the prepreg tape to be tested and opposite to the probe, the input end of the probe is connected with a near infrared spectrometer through optical fiber, and the near infrared spectrometer is connected with a computer. The invention can acquire the quality information of the prepreg in a online real-time manner, rapidly reflects the changes of each quality indicator in the prepreg tape to be tested and data detection and production process are carried out synchronously, andthe detection results are accurate.

Description

technical field [0001] The invention relates to a device for detecting the quality index of a prepreg tape. Background technique [0002] Prepreg (also called prepreg tape) is an intermediate material for the manufacture of composite materials, and the performance of composite materials depends to a large extent on the performance of prepreg. Resin content and volatile matter content are the main quality indicators of prepreg tape. At present, the monitoring of quality indicators in the process of prepreg manufacturing at home and abroad attaches great importance, and more research has been carried out, mainly including ray transmission, infrared scanning, Technologies such as sonication and weight monitoring. These monitoring techniques have high sensitivity and some have been used in practice. However, they are mainly used to monitor the resin content of prepregs, but cannot measure the volatile content. The Chinese patent No. ZL03132466.5 applied by Harbin Institute of ...
