Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] Example 1:

[0041] The embodiment of the present invention provides a method for detecting carbon fiber materials with automatic reeling and unreeling, such as Figure 1 As shown, including:

[0042] Step 1: Using an automatic rewinding and unwinding device, the carbon fiber material to be tested is rewound and unwound at multiple fixed points along the length direction of the coil;

[0043] Carbon fiber materials are usually made into coils during production, and they need to be unfolded when they need to be measured. To unfold the carbon fiber materials, an automatic unwinding and rewinding device is needed to unwind and rewind the carbon fiber materials. After the coils are unfolded, fixed-point detection is performed in the length direction of the coils. The automatic unwinding and rewinding device includes: a unwinding unit, a flattening unit and a rewinding unit. The unwinding unit is used to unwind the carbon fiber materials to be tested; the flattening unit is used to flatten the carbon fiber materials to be tested released by the unwinding unit; the rewinding unit is used to rewind the carbon fiber materials to be tested at the discharge end of the flattening unit. The unwinding unit includes: a unwinding roller and a first roller-type conveying device; the flattening unit includes: a long strip platform and a clamping device arranged at both ends of the long strip platform; the rewinding unit includes: a rewinding roller and a second roller-type conveying device.

[0044] Step 2: When each point is in place, data of the carbon fiber material to be tested performed by at least one detection unit is obtained and detection data is generated based on the obtained data and the measurement standard;

[0045] For the detection of the carbon fiber material to be tested, an image acquisition unit is usually used, and the image collected by the image acquisition unit is analyzed to realize the detection. The detection aspects include: product width, whether the product has defects, edge straightness, etc.; therefore, the detection unit includes: multiple image acquisition units configured above the long strip platform. It can be properly configured according to the situation. For example: if the unfolded length is 8 meters, an image acquisition unit is configured at the positions of 0m, 4m, and 8m respectively; if the unfolded length is 6 meters, an image acquisition unit is configured at the positions of 0m, 3m, and 6m respectively. Since the image acquisition unit is only configured on the top, and the carbon fiber material to be tested has two sides, the front and back sides can be tested separately by unwinding and rewinding twice;

[0046] Since each receiving party has different requirements for coils, the standards of each receiving party are uniformly stored in the standard storage library. In actual use, the steps for retrieving the measurement standards are as follows: the identification code of the carbon fiber material to be tested is identified by the identification unit configured at the unwinding end of the automatic rewinding and unwinding device, and the receiving party determination library is queried based on the identification code to determine the receiving party of the carbon fiber material to be tested; the measurement standard corresponding to the receiving party is retrieved from the standard storage library. Among them, the identification code can be a QR code, barcode, etc. attached to the roll of the coil. The specific receiving party can be determined from the receiving party determination library through identification by the identification unit (for example: a barcode scanner), and the corresponding standard can be extracted; the receiving party determination library will configure the corresponding receiving party for each coil when the coil is produced, and it is at this time that it is determined to which receiving party the coil is sent.

[0047] Step 3: After all points have been inspected, the inspection data is linked to the image data captured by the image acquisition device that captured the entire inspection process to form an electronic record. By linking the captured inspection process images with the inspection data, the receiving party can accurately verify the inspection process and the authenticity of the inspection data.

[0048] The present embodiment of the automatic rewinding and unwinding carbon fiber material testing method automatically detects and forms an electronic record, which is simultaneously provided to downstream enterprises when they purchase, thus avoiding the need for secondary testing by downstream enterprises. The edge of the coil corresponding to the first test point of the coil can be marked. Furthermore, to facilitate subsequent tracing and positioning of the test points, the edge of the coil corresponding to all test points can be marked. The marks correspond to the sequence code of the points, which is based on the test rounds on the automatic rewinding and unwinding device and the codes of the corresponding test units.

[0049] Example 2:

[0050] The embodiment of the present invention provides a method for detecting carbon fiber materials with automatic reeling and unreeling, such as Figure 1 Shown, including:

[0051] The automatic rewinding and unwinding device is used to perform fixed-point rewinding and unwinding operations on the carbon fiber material to be tested at multiple points in the length direction of the coil;

[0052] When each point is in place, data detected by at least one detection unit on the carbon fiber material to be detected is obtained and detection data is formed based on the obtained data and the measurement standard;

[0053] After all the detections corresponding to the points are completed, the detection data is associated with the image data collected by the image acquisition device that captures the entire detection process to form an electronic record.

[0054] The automatic unwinding and rewinding device includes: a material unwinding unit, a flattening unit and a material receiving unit;

[0056] Among them, the unloading unit includes: a unloading roller and a first roller-type material transport device; the flattening unit includes: a long strip platform and clamping devices arranged at both ends of the long strip platform; the receiving unit includes: a receiving roller and a second roller-type material transport device.

[0057] The detection unit includes: a plurality of image acquisition units arranged above the long strip platform and a plurality of image acquisition units arranged below the long strip platform;

[0058] A shooting window is provided at a position of the long strip platform corresponding to the image acquisition unit below.

[0059] The steps for retrieving the measurement standard are as follows:

[0060] The identification unit configured at the unwinding end of the automatic unwinding and rewinding device identifies the identification code of the carbon fiber material to be tested, queries the receiving party determination library based on the identification code, and determines the receiving party of the carbon fiber material to be tested;

[0061] Retrieve the measurement standards associated with the material receiving party from the standard repository.

[0062] The automatic reeling and unreeling carbon fiber material detection method of this embodiment adopts a detection unit that is not only configured with an image acquisition unit on the top, but also has a shooting window below the long strip platform. The image acquisition unit is synchronously configured to capture images from the shooting window, thereby achieving the goal of completing the detection of both sides by reeling and unreeling once, thereby improving the detection efficiency.

[0063] Example 3:

[0064] The embodiment of the present invention provides a method for detecting carbon fiber materials with automatic reeling and unreeling, such as Figure 1 Shown, including:

[0065] The automatic rewinding and unwinding device is used to perform fixed-point rewinding and unwinding operations on the carbon fiber material to be tested at multiple points in the length direction of the coil;

[0066] When each point is in place, data detected by at least one detection unit on the carbon fiber material to be detected is obtained and detection data is formed based on the obtained data and the measurement standard;

[0067] After all the detection points are completed, the detection data is associated with the image data collected by the image acquisition device that captures the entire detection process to form an electronic record.

[0068] The automatic unwinding and rewinding device includes: a material unwinding unit, a flattening unit and a material receiving unit;

[0069] Among them, the unwinding unit is used to unwind the carbon fiber material to be tested; the flattening unit is used to flatten the carbon fiber material to be tested released by the unwinding unit; the receiving unit is used to rewind the carbon fiber material to be tested at the discharge end of the flattening unit;

[0070] Among them, the unloading unit includes: a unloading roller and a first roller-type material transport device; the flattening unit includes: a long strip platform and clamping devices arranged at both ends of the long strip platform; the receiving unit includes: a receiving roller and a second roller-type material transport device.

[0071] The detection unit includes: a plurality of image acquisition units arranged below the long strip platform;

[0072] A shooting window is provided at a position of the long strip platform corresponding to the image acquisition unit below.

[0073] The steps for retrieving the measurement standard are as follows:

[0074] The identification unit configured at the unwinding end of the automatic unwinding and rewinding device identifies the identification code of the carbon fiber material to be tested, queries the receiving party determination library based on the identification code, and determines the receiving party of the carbon fiber material to be tested;

[0075] Retrieve the measurement standards associated with the material receiving party from the standard repository.

[0076] The steps for determining the point are as follows:

[0077] Analyze the retrieved measurement standard to obtain the first sampling rule;

[0078] The usage data fed back by the material receiver is analyzed to obtain a second sampling rule. The usage data analysis specifically includes: retrieving a corresponding mapping rule from a pre-configured mapping rule library based on the method number representing the usage method in the usage data; mapping the usage data to the length of the coil according to the retrieved mapping rule; extracting points along the length of the coil where usage data anomalies occur, and generating a second sampling rule based on the extracted points. Here, the usage data needs to be recorded according to the usage of the coil, for example: the number of products produced for coil lengths N to M, product inspection yield, defect type, and defect parameters. Not all defects are caused by defects in the coil itself, so when extracting points along the length of the coil where usage data anomalies occur, extraction is performed based on a pre-configured defect table, that is, the defects (anomalies) mentioned in the defect table are extracted. The second sampling rule is generated by pre-sampling the coil based on all sampling rules in the pre-configured second sampling rule library to obtain sampling points, and the second sampling rule with the largest number of overlapping sampling points and the extracted points is used as the final second sampling rule.

[0079] Combining the first sampling rule and the second sampling rule, the point position is determined along the length direction of the coil.

[0080] This embodiment of the automatic rewinding and unwinding carbon fiber material testing method analyzes usage data provided by the receiving party based on their measurement standards, further ensuring accurate and effective coil testing. To achieve correlation between testing and usage, the coils are marked along their lengths during production, based on the production run lengths. The corresponding positions of different runs are aligned with the production equipment during production. The recording of usage data and the determination of test points during testing are mapped to the production markings.

[0081] In addition, when the material receiving party uses the coil to produce a new product, since there is no usage data for the new product, the usage data of other products can be borrowed. The specific borrowing steps are as follows: analyze and quantify the parameters of the finished products and production process parameters of the new product and other products to construct a description parameter set; calculate the similarity between the description parameter set of the new product and the description parameter set of other products; determine the first analysis value corresponding to the similarity based on the pre-configured first analysis value determination table; extract features of the data volume and generation time of the usage data, and determine the second analysis value from the pre-configured second analysis value determination table based on the extracted feature parameters (feature parameters representing the data volume, feature parameters representing the time of the most recent data, feature parameters representing the average time interval between two adjacent usage data, etc.), and borrow the usage data of other products with the largest first analysis value and second analysis value to generate a second sampling rule; after the new product starts production, use the usage data of the new product to eliminate the data with a longer time from the current time in the borrowed usage data in sequence until all the borrowed data is replaced. Among them, the data contained in the description parameter set include: parameters representing the number of steps in the production process, parameters representing the process code of each production process, parameters representing the configuration data in each production process, parameters representing the shape of the finished product, parameters representing the dimensions of each part of the finished product, etc.
