Description

Technical Field

[0001] The invention belongs to the field of carbon fiber equipment and relates to a size detection technology, in particular to a carbon fiber composite material product size detection system and a detection method. Background Art

[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It is the best in high temperature resistance among all chemical fibers. It is made of acrylic and viscose fibers and is oxidized and carbonized at high temperature. It is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber is mainly composed of carbon elements and has the characteristics of high temperature resistance, friction resistance, thermal conductivity and corrosion resistance. It is fibrous, soft and can be processed into various fabrics. Because its graphite microcrystalline structure is preferentially oriented along the fiber axis, it has high strength and modulus along the fiber axis. Carbon fiber has a low density, so it has high specific strength and specific modulus. The main use of carbon fiber is as a reinforcing material to be compounded with resin, metal, ceramic and carbon to manufacture advanced composite materials. Carbon fiber reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials.

[0003] In the prior art, after carbon fiber is manufactured, when carbon fiber composite materials products of the same length, width and different thickness are arranged, individual materials are usually measured one by one. Errors are likely to occur during measurement, and multiple inspections and observations cannot be performed. The thickness of the composite products is not measured multiple times for comparison, which affects the accuracy of the thickness measurement of the composite products. To this end, we propose a carbon fiber composite product size detection system and detection method. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a carbon fiber composite material product size detection system and detection method.

[0005] The technical problems to be solved by the present invention are:

[0006] (1) In the prior art, when measuring the thickness of a composite product, it is not possible to accurately measure its thickness, which affects the accuracy of the measurement of the composite product;

[0007] (2) In the prior art, composite products need to be collected and sorted after measurement, which wastes a lot of time.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A carbon fiber composite material product size detection system comprises a material conveying module, a weight measuring module, a material arranging module, a thickness detecting module and a data analyzing module. The material conveying module scans and measures a single composite product and conveys it to the material arranging module. The material arranging module stacks and arranges the composite products conveyed thereto. The thickness detecting module measures the thickness of the composite products in the material conveying module and the material arranging module. The weight measuring module detects the weight of the composite products in the material conveying module and the material arranging module. The thickness detecting module and the weight measuring module are data-connected to a data analyzing module. The data analyzing module receives numerical information from the thickness detecting module and the weight measuring module for calculation.

[0010] Furthermore, the material conveying module includes a composite product conveying part and a scanning part. The composite product conveying part includes a conveying motor, a conveying gear and a conveyor belt. The conveying gear is provided with two groups. The two groups of conveying gears are meshed with the inner wall of the conveyor belt at both ends inside the conveyor belt. One group of the conveying gears is connected to the conveying motor. A plurality of groups of V-shaped limit blocks for limiting the composite product are installed on the conveyor belt. A first gravity sensor for weighing the composite product is provided on the inner side of the V-shaped limit block. A first distance sensor for vertical measurement is provided above the first gravity sensor. A scanning part is provided on one side of the first distance sensor. A plurality of first gravity sensors are provided. The plurality of first gravity sensors are equidistantly arranged on the conveyor belt. The first gravity sensor data is connected with a weight measurement module. The first distance sensor data is connected with a thickness detection module. The conveying motor data is connected with a central control module. A material arrangement module is provided at the tail end of the composite product conveying part.

[0011] Furthermore, the scanning device includes an infrared scanner and a piece counter. The infrared scanner scans the composite product on the conveyor belt. When the composite product is scanned, the piece counter counts the product. The central control module controls the first distance sensor to measure the distance between the surface of the composite product and the first distance sensor, and transmits the distance information to the thickness detection module. The thickness detection module records the distance between the first composite product and the first distance sensor as L1, the distance between the second composite product and the first distance sensor as L2, and the distance between the nth composite product and the first distance sensor as Ln. The first distance sensor is set to measure the distance between the first gravity sensor as L. The thickness detection module receives and organizes the numerical information, and transmits the organized numerical information to the data analysis module. The weight measurement module records the weight of the first composite product as M1, the weight of the second composite product as M2, and the weight of the nth composite product as Mn. The weight measurement module receives and organizes the numerical information, and transmits the organized numerical information to the data analysis module.

[0012] Furthermore, the material arrangement module includes an arrangement frame, a collecting plate, a lifting plate and a lifting member. The arrangement frame is arranged at the discharge end of the conveyor belt, and a lifting plate that can move up and down along the arrangement frame is installed inside the arrangement frame. A collecting plate for placing composite products is embedded inside the lifting plate. A lifting member for driving the lifting plate to move up and down is arranged inside the arrangement frame. An infrared laser is arranged at one end of the top of the arrangement frame, and a position sensor is installed on the lifting plate. The infrared laser is data-connected to the central control module, and the position sensor is data-connected to the thickness detection module. A second gravity sensor is arranged on the lifting plate, and the second gravity sensor is data-connected to the weight measurement module.

[0013] Furthermore, the lifting component includes a lifting screw, a transmission chain, a chain plate and a transmission motor. Lifting screws are installed at both ends of the arrangement frame, a chain plate is installed at the bottom of the lifting screw, a transmission motor is installed at the bottom of the arrangement frame, and a chain plate is installed on the transmission motor. The three groups of chain plates are connected by a transmission chain. Transmission blocks threadedly connected to the lifting screw are fixed at both ends of the lifting plate, and the transmission motor is connected to the central control module.

[0014] Furthermore, the data analysis module includes a data range analysis unit, a data calculation unit and a numerical output unit. The data range analysis unit receives data information between the weight measurement module and the thickness detection module, analyzes the data information, analyzes the size of the measured value, sets the maximum thickness value of the composite product through the central control module, and if the measured value is greater than the set value, removes the value, manually re-measures the recorded plate, calculates multiple numerical information through the numerical calculation unit, and sums the obtained value with the manually measured value.

[0015] A method for detecting the size of a carbon fiber composite material product, the method comprising the following steps:

[0016] Step S1: The material transport module transports the composite product and measures the height and weight of the transported composite product;

[0017] Step S2: The measured composite products are neatly arranged by the material arrangement module, and after the arrangement is completed, the gravity and height are measured again, and the measurement information is transmitted to the data analysis module for analysis and comparison;

[0018] Step S3: Evaluate the values ​​through the data analysis module, and compare the values ​​of the two groups of evaluations to determine whether the test values ​​are the same when the thickness test is performed. If the values ​​are the same, it proves that the size of the composite product is correct when the thickness test is performed. If the values ​​are different, analyze the cause of the error and perform retesting.

[0019] Step S4: The arranged composite materials are collected uniformly.

[0020] Furthermore, in step S1, the scanning part in the material conveying module scans the composite product, and the composite product is conveyed by the composite product conveying part. When the composite product is conveyed on the conveyor belt, the first gravity sensor detects the pressure of the composite product, and the first gravity sensor transmits the gravity information to the weight measurement module. The first distance sensor measures the distance between the composite product and the weight measurement module. When the detection is completed, the first distance sensor transmits the distance information to the thickness detection module.

[0021] Furthermore, when the first gravity sensor is detecting, the weight of the first composite product is recorded as M1, the weight of the second composite product is recorded as M2, and the weight of the nth composite product is recorded as Mn. When the first distance sensor is detecting, the distance between the first composite product and it is recorded as L1, the distance between the second composite product and it is recorded as L2, and the distance between the nth composite product and it is recorded as Ln. The first distance sensor measures the distance between the first gravity sensor as L, and calculates the difference between L and L1, L2, L3...Ln respectively to obtain the thickness of the composite product.

[0022] Furthermore, in the step S2, the composite product is conveyed to the collecting plate of the material arrangement module. When conveyed to the collecting plate, the infrared laser detects that the composite product is placed on the collecting plate, and transmits the data information to the central control module. The central control module controls the lifting member to drive the lifting plate to move downward. When the infrared laser does not detect the object, it sends feedback information, and the central control module stops controlling the transmission of the lifting member, so that the lifting plate does not continue to move downward. When the lifting member receives the instruction and works, the position sensor transmits the position information to the thickness detection module, and the thickness detection module records the input value as H1. When the composite product is collected, the position sensor sends its position information to the thickness detection module again, and the thickness detection module records the input value as H2.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can detect the composite products when they are placed by setting an infrared laser instrument, and transmit the data information to the central control module after the composite products are placed. The central control module controls the lifting member to drive the lifting plate to move downward, so that the composite products are placed at the same height each time, and the measured products are uniformly and neatly arranged and collected, saving manpower;

[0025] 2. The composite product of the present invention measures gravity through the first gravity sensor and the first distance sensor when being transported, and after collection, the placement height is fed back through the position sensor, and the overall weight is measured through the second gravity sensor. By comparing the data information, when the thickness of the composite product is measured, its thickness can be accurately measured, thereby improving the accuracy of the composite product measurement;

[0026] 3. The present invention can adjust the position of the lifting plate by setting a lifting member, so that the composite plates will not be arranged in a disorderly manner due to height during collection, and the arrangement can be more orderly. BRIEF DESCRIPTION OF THE DRAWINGS

When the composite product is scanned, the piece counter counts the product, and the metering time of the corresponding product is synchronized with the weight measured by the first gravity sensor. The central control module controls the first distance sensor to measure the distance between the surface of the composite product and the first distance sensor, and transmits the distance information to the thickness detection module. The thickness detection module records the distance between the first composite product and the first distance sensor as L1, the distance between the second composite product and the first distance sensor as L2, and the distance between the nth composite product and the first distance sensor as Ln.

[0036] According to the measured values, the thickness of the first composite product is L-L1, the thickness of the second composite product is L-L2, and the thickness of the third composite product is L-L3. Therefore, the thickness of the nth composite product is L-Ln. The data analysis module evaluates the overall height Lz, and Lz = L-L1 + L-L2 + L-L3 +...L-Ln. The overall weight Mz = M1 + M2 + M3 +.....Mn.

[0037] The material arrangement module includes an arrangement frame 1, a collecting plate 3, a lifting plate 2 and a lifting member.

The up and down movement of the transmission block 6 drives the lifting plate 2 to move downward. The downward movement of the lifting plate 2 drives the collecting plate 3 to move downward, and the height of the composite product on the collecting plate 3 is adjusted. A square force groove 11 is provided at the bottom of the collecting plate 3. The collecting plate 3 is conveniently separated from the lifting plate 2 through the square force groove 11 after collection.

[0039] The data analysis module includes a data range analysis unit, a data calculation unit and a numerical output unit. The data range analysis unit receives the data information between the weight measurement module and the thickness detection module, analyzes the data information, analyzes the size of the measured value, sets the maximum thickness value of the composite product through the central control module, if the measured value is greater than the set value, the value is removed, the recorded plate is manually re-measured, the numerical calculation unit calculates multiple numerical information, and the obtained value is summed with the manually measured value.

If it exceeds the set value, the product that exceeds the measured value is re-measured, and the central processing module deletes the corresponding data in the data analysis module. After the manual measurement is completed, the data analysis module reads the data and recalculates.

[0040] A carbon fiber composite material product size detection system and detection method, when working, specifically includes the following steps:

[0041] Step S1: The material transport module transports the composite product and measures the height and weight of the transported composite product;

[0042] The scanning part in the material conveying module scans the composite product and conveys it through the composite product conveying part 4. When the composite product is conveyed on the conveyor belt, the first gravity sensor detects the pressure of the composite product. The first gravity sensor transmits the gravity information to the weight measurement module, and the first distance sensor measures the distance between the composite product and it. When the detection is completed, the first distance sensor transmits the distance information to the thickness detection module.

[0043] When the first gravity sensor is detecting, the weight of the first composite product is recorded as M1, the weight of the second composite product is recorded as M2, and the weight of the nth composite product is recorded as Mn. When the first distance sensor is detecting, the distance between the first composite product and it is recorded as L1, the distance between the second composite product and it is recorded as L2, and the distance between the nth composite product and it is recorded as Ln. The first distance sensor measures the distance between the first gravity sensor as L, and calculates the difference between L and L1, L2, L3...Ln respectively to obtain the thickness of the composite product. The thickness of the first composite product is L-L1, the thickness of the second composite product is L-L2, and the thickness of the third composite product is L-L3. Therefore, the thickness of the nth composite product is L-Ln. The data analysis module evaluates the overall height Lz, and Lz=L-L1+L-L2+L-L3+...L-Ln, and the overall weight Mz=M1+M2+M3+.....Mn.

[0044] Step S2: The measured composite products are neatly arranged by the material arrangement module, and after the arrangement is completed, the gravity and height are measured again, and the measurement information is transmitted to the data analysis module for analysis and comparison;

[0045] The composite product is transported to the collecting plate 3 of the material arrangement module. When it is transported to the collecting plate 3, the infrared laser instrument 5 detects that the composite product is placed on the collecting plate 3, and transmits the data information to the central control module. The central control module controls the transmission motor 9 to work. The transmission motor 9 works to rotate the three sets of chain plates 8 through the transmission chain 10. The rotation of the chain plate 8 drives the lifting screw 7 to rotate. The rotation of the lifting screw 7 drives the transmission block 6 to move up and down through the threaded connection. The up and down movement of the transmission block 6 drives the lifting plate 2 to move downward. The downward movement of the lifting plate 2 drives the collecting plate 3 to move downward. When the infrared laser instrument 5 does not detect the object, it sends feedback information, and the central and control module stops controlling the transmission. The motor 9 works to stop the lifting plate 2 from moving downward. When the lifting member receives the instruction and works, the position sensor transmits the position information to the thickness detection module, and the thickness detection module records the input value as H1. When the composite product is collected, the position sensor sends its position information to the thickness detection module again, and the thickness detection module records the input value as H2. The total height of the composite product Hz = H2-H2, and Hz is compared with Lz. If the values ​​are the same, it proves that the thickness measurement is accurate. If the values ​​are different, the total weight Mg is calculated by the second gravity sensor, and the values ​​of Mg and Mz are compared to observe whether the weights are the same and whether there is a measurement error.

[0046] Step S3: Evaluate the values ​​through the data analysis module, and compare the values ​​of the two groups of evaluations to determine whether the test values ​​are the same when the thickness test is performed. If the values ​​are the same, it proves that the size of the composite product is correct when the thickness test is performed. If the values ​​are different, analyze the cause of the error and perform retesting.

[0047] Step S4: The arranged composite materials are collected uniformly.

[0048] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions. The size of the weight coefficient and the proportional coefficient is to quantify each parameter to obtain a specific value, which is convenient for subsequent comparison. Regarding the size of the weight coefficient and the proportional coefficient, as long as it does not affect the proportional relationship between the parameter and the quantized value, it is fine.

When the lifting member receives the instruction and works, the position sensor transmits the position information to the thickness detection module, and the thickness detection module records the input value as H1. When the composite product is collected, the position sensor sends its position information to the thickness detection module again, and the thickness detection module records the input value as H2.
