After inputting easily discernible relative parameters in the program writing unit, difficult-to-determine inputs are computed. This is further complemented by executing the computation unit to calculate the linear winding result. Ultimately, the system allows for the modification of relevant parameters and immediate feedback on the results after each parameter modification.

Description

Intelligent carbon fiber winding programming system

The present invention relates to a winding machine programming field, and more particularly to an intelligent carbon fiber winding programming system that can greatly simplify the difficulty of programming.

Carbon fiber composite high-pressure gas cylinders are usually manufactured using a carbon fiber winding process. In this process, the carbon fiber is impregnated with epoxy resin under tension, then wound around a rotating mandrel, and finally cured to complete the molding process. However, during the winding process, the winding path of the carbon fiber needs to be set in advance, which includes calculating the path according to the size of the liner, and also involves parameters such as the winding block, angle and overlap rate. These settings make the winding path program design very complicated, especially in the widely used winding machine programming system. Most of them adopt the common CNC systems on the market. These systems use CAM software or manually input the winding path program to compile the winding program based on the CNC machining mode.

However, this method requires programmers to have a high level of technical skills, and the adjustment of the program is relatively difficult, resulting in low programming efficiency. To solve these problems, this work believes that it is necessary to develop a more intelligent and efficient carbon fiber winding programming system, which can automatically generate a suitable winding path program according to the bladder size and other related parameters, reducing the technical requirements of programmers. At the same time, an intuitive interface and easy-to-adjust functions should be provided to make programming more flexible and efficient. The intelligent programming system of this work will greatly improve the efficiency and quality of carbon fiber composite high-pressure gas cylinder production, while reducing production costs, and bring more possibilities for the development of the carbon fiber composite industry.

In view of this, the inventor has been engaged in the manufacturing, development and design of related products for many years. After careful design and careful evaluation, he finally obtained the present invention which is truly practical.

The interface of the winding path planning unit displays a winding graphic page, which displays the selected object graphic and the yarn nozzle head graphic, and the corresponding fields of the winding path parameters are marked around the object graphic. When the parameters of the corresponding fields are adjusted, the yarn nozzle head graphic will be synchronously moved to the relative distance position of the object graphic.

The part dimension fields 23 include the shaft center diameter, shaft center length, shaft head diameter, shaft head length, head end arc surface length, middle section length, middle section diameter, and tail end arc surface length. When the parameters of the part dimension fields 23 are adjusted, the object graphic will change the displayed graphic ratio synchronously. A winding path planning unit 30 is used to set a winding path parameter 31. The winding path parameter 31 is automatically calculated based on the yarn bundle parameter 11 selected by the yarn bundle database unit 10 and the object size parameter 21 selected by the object database unit 20 to obtain the allowable range value of the winding path parameter 31, and then the self-set parameters are filled in the allowable range value. The winding path parameter 31 includes the head end swing angle, the head end boundary displacement, the head end boundary advance The interface of the winding path planning unit 30 displays a winding graphic page 32, which displays the selected object graphic and the yarn nozzle head graphic, and the corresponding fields of the winding path parameters 31 are marked around the object graphic. When the parameters of the corresponding fields are adjusted, the yarn nozzle head graphic will be synchronously moved to the relative distance position of the object graphic. A program writing unit 40 includes a winding mode parameter 41, a winding sequence parameter 42 and an angle control parameter 43. The winding mode parameter 41 includes a large-angle circular mode and a small-angle spiral mode. The winding mode parameter 41 further includes an offset value parameter 411 and a winding pitch parameter 412. The offset value parameter 411 is the offset between the starting position of the yarn nozzle head and the parameter setting position, and the winding pitch parameter 412 is the offset of the next circle when the circular winding is selected. The winding sequence parameter 42 includes the number of block divisions, the block winding sequence and the number of loop winding times. After selecting and filling in the winding mode parameter 41 and the winding sequence parameter 42, the angle control parameter 43 can be automatically calculated. Among them, the angle control parameter 43 includes the main shaft yarn return rotation angle of the head end, the main shaft yarn rotation reserved angle of the head end, and the head The angle control parameter 43 includes a winding angle reference value 44, which is a plurality of winding angle combinations automatically calculated by the program to provide selection. An execution unit 50 calculates all parameters of the yarn database unit 10, the object database unit 20, the winding path planning unit 30 and the program writing unit 40 to generate a linear winding result 51. The linear winding result 51 includes the yarn length used, the yarn weight and the thickness of the yarn wound around the object. After the linear winding result 51 is generated, all or part of the parameters can be adjusted again, and the adjusted linear winding result 51 can be displayed in real time.

The actual operation steps are shown in Figure 1 to Figure 6. The intelligent carbon fiber winding programming system of this invention is a control programming system of a five-axis winding machine. Through the programming of the programming system, the five-axis winding machine can perform carbon fiber yarn winding processing on the object (liner) to obtain a plastic liner fiber winding bottle. The programming system mainly The system comprises: a yarn database unit 10, an object database unit 20, a winding path planning unit 30, a program writing unit 40 and an execution operation unit 50. The above units can be presented in a display window in the form of menu pages, so that the user can press to select and intuitively complete all parameter inputs in sequence, as described below:

Step 1: Click the yarn database unit 10, and a project name field for input will pop up. After input, the yarn parameter 11 to be used is selected through the big data of the yarn database unit 10. The parameter items of the yarn parameter 11 include the width, thickness and gram weight per unit length of the yarn. Since the yarn rolls are marked with the width, thickness and gram weight per unit length of the yarn, when selecting yarn rolls of different items, the corresponding yarn parameter 11 can be directly selected. If the yarn roll is not archived, it can also be manually input.

Step 2: Click on the object database unit 20. The object may be a liner of a gas cylinder. In the display screen, one of the object types can be directly selected: a flat cone tube, a flat end winding, a high-pressure gas cylinder with a single end clamp, a high-pressure gas cylinder with two ends clamped, and a spherical winding. After the selection, the object graphic page 22 is entered. Since most objects (liners) are standard specifications, they can be directly built into the object database unit 20 for selection, thereby deriving all the dimensional parameters of the object, such as the axis diameter, axis length, If the shaft head diameter, shaft head length, length of the head end arc surface, middle section length, middle section diameter and tail end arc surface length need to be manually set, the object graphic page 22 displays the object graphic, and a plurality of part size fields 23 are marked around the object graphic. When the parameters of the part size fields 23 are adjusted, the object graphic will change the displayed graphic ratio synchronously, so that the correct size parameters can be intuitively input at the accurate position, thereby effectively reducing the difficulty of setting the object size parameters 21.

Step 3: Click the winding path planning unit 30. At this time, the programming system will perform preliminary calculations. Under the conditions of limiting the yarn bundle parameter 11 and the object size parameter 21, the allowable range of the winding path parameter 31 is derived. The allowable range is calculated based on a relatively low yarn usage and built-in finished product data. In other words, the system first provides a parameter range that can complete the processing, and then provides the user with a judgment basis for inputting parameters, allowing the user to fill in the parameters set by themselves within the allowable range. The winding path parameter 31 includes the head end The swing angle, the displacement of the head end boundary, the advance of the head end boundary, the swing angle of the tail end, the advance of the tail end boundary and the distance from the yarn guide nozzle to the object surface, the winding path parameter 31 will be displayed on the winding graphic page 32, and the winding graphic page 32 displays the selected object graphic and the yarn nozzle head graphic. When the parameters of the corresponding columns are adjusted, the yarn nozzle head graphic will be synchronously displaced to the relative distance position of the object graphic. Through the display of the relative columns and the change of the graphics, the user can clearly know what results will be produced when adjusting the parameters, thereby providing a friendly and easy-to-understand operation interface.

Step 4: Click the program writing unit 40, and select the winding mode parameter 41 and the winding sequence parameter 42. The winding mode parameter 41 includes a large-angle winding mode and a small-angle spiral mode, that is, the user can form a large-angle winding mode in the middle of the bladder, and select a small-angle spiral mode at the arcs at both ends of the bladder. The winding sequence parameter 42 includes The number of block divisions, block winding sequence, and number of loop winding times are included. For example, the middle section of the bladder and the arcs on both sides are set as three blocks, and the winding sequence of the three blocks and the number of loop winding times (layers) are set. The above selections and parameter inputs are easy for users with considerable technical background to input, so it will not cause trouble for users when inputting parameters. After the winding mode parameter 41 and the winding sequence parameter 42 are set, the system can automatically calculate and generate the angle control parameter 43. The angle control parameter 43 includes the main shaft yarn return rotation angle at the head end, the main shaft yarn rotation reserved angle at the head end, the rotating head yarn rotation pre-stop angle at the head end, the rotating head yarn rotation pre-stop angle at the tail end, the main shaft yarn return rotation angle at the tail end, and the main shaft yarn rotation reserved angle at the tail end. Since the angle control parameter 43 is difficult for non-highly professional personnel to directly input, or after input, a large number of simulation tests are required to confirm whether the input parameters can be adopted, therefore, this invention uses the technical means of step-by-step, intuitive and big data computing used in programming to greatly reduce the user's parameter input, which can effectively reduce the requirements on the user's programming ability.

Step 5: Click the execution unit 50, the execution unit 50 calculates all the parameters of the yarn database unit 10, the object database unit 20, the winding path planning unit 30 and the program writing unit 40 to generate a linear winding result 51. The linear winding result 51 will display the yarn length, yarn weight and yarn thickness of the object on the display screen, so that the user can judge It is possible to judge whether the condition parameters previously input are reasonable and correct. If they are not satisfactory, there is no need to re-enter all of them. After the linear winding result 51 is generated, all or part of the parameters can be adjusted again by clicking on different display windows. The linear winding result 51 will be displayed on one side synchronously, and the adjusted linear winding result 51 can be displayed in real time, making program programming more intuitive and easier to modify to the optimal parameter value.

In summary, the advantage of the intelligent carbon fiber winding programming system of the present invention is that a person with ordinary knowledge in the relevant technical field can select the type of the yarn bundle database unit 10 and the object database unit 20 according to the steps, and input parameters within the allowable range of the winding path planning unit 30, and after inputting the relative parameters that are easy to judge the input into the program writing unit 40, perform calculations to obtain the unpredictable The parameter part of the input is easy to judge, and then the linear winding result 51 derived by the execution operation unit 50 is judged whether it is close to the optimal parameter. Finally, it can return to modify the relevant parameters and respond to the results of each single parameter modification in real time. That is, through modularization, intuitiveness and big data computing technology, the user's operation difficulty is reduced, so as to effectively improve work efficiency and ensure output quality.

The intelligent carbon fiber winding programming system of this invention further includes a parameter feedback unit 60, as shown in FIG1 . The parameter feedback unit 60 signals the data of the actual yarn usage, resin usage, resin residue, final winding thickness, ambient temperature, ambient humidity, winding tension, winding speed and processing time. The above data are obtained through user input, sensor detection, timer and measurement of finished products. The actual operation data will be recorded in the parameter feedback unit 60. After collecting enough data, the linear winding result 51 calculated by the execution operation unit 50 can be weighted and adjusted according to a large amount of data. For example, when the ambient temperature is higher, the yarn length, yarn weight and the thickness of the yarn wrapped around the object in the linear winding result 51 will increase by a corresponding proportion, thereby reducing the possibility of users misjudging the production results.

To further explain, as shown in FIG. 6 , the execution unit 50 further includes a reverse execution button 52. After the reverse execution button 52 is activated, the linear winding result 51 can be manually adjusted, and the adjusted linear winding result 51 can be used for reverse operation. The system default value and large data are used to perform the smallest amplitude fine adjustment of all or part of the parameters, that is, the appropriate parameters can be derived from the result in reverse. , thereby providing another option other than returning to manual adjustment parameters, wherein, after the execution operation unit 50 activates the reverse execution button 52, the yarn bundle parameter 11, the object size parameter 21, the winding path parameter 31, the winding mode parameter 41, the winding sequence parameter 42, and the angle control parameter 43 will all be added with a control field 521, and the control field 521 includes There are lock, micro lock and unlock options. When the control field 521 is locked, the reverse operation will not adjust the specified parameters, and the unlocked parameters will be fine-tuned. When the control field 521 is micro-locked, the specified parameters will be adjusted after the reverse operation. In other words, the programming system will not adjust the micro-locked parameters when it is not necessary. Another solution for setting the fine-lock is to limit the range of fine-tuning of the specified parameter, for example, the adjustable range is plus or minus 5%. Accordingly, by using the reverse execution button 52 and the selection of the control field 521, it is possible to effectively perform quick fine-tuning after setting the parameters, so that the programming system can adjust to a better winding scheme according to the user's ideas, so as to intelligently carry out its carbon fiber winding processing process.

However, what is described above is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention; that is, all equivalent changes and modifications made within the scope of the patent application of the present invention should still fall within the scope of coverage of the patent of the present invention.
