Description

Technical Field

[0001] The present invention belongs to the technical field of carbon fiber processing, and particularly relates to an efficient large-tension tape continuous automatic winding and defect monitoring device and an operation method thereof. Background Art

[0002] With the continuous progress of materials science, this high-performance material, carbon fiber, has gradually been recognized and valued by people. Carbon fiber has excellent properties such as high strength, high modulus, low density, and corrosion resistance, and has broad application prospects in the fields of aerospace, automotive, sports goods, etc. However, the processing and forming technologies of carbon fiber materials are relatively complex and require special equipment for treatment. The carbon fiber tape winding machine came into being under such a demand. It can wind carbon fiber tapes around mandrels of various shapes according to specific process requirements to produce carbon fiber products with specific shapes and properties.

[0003] Currently, numerically controlled tape winding machines are not yet mature and there are still many problems. For example, the production efficiency is low, there is a lot of work that requires human participation, which easily causes defective products; although the tape winding machine has improved the production efficiency to a certain extent, compared with some production equipment with higher automation levels, its winding speed is still limited. Especially in the case of large-scale production, the production efficiency of the tape winding machine may not meet the requirements; it needs to be maintained and serviced regularly to ensure its normal operation and extend its service life.

[0004] The maintenance cost includes expenses such as replacing vulnerable parts, performing equipment calibration and repair. The operation of the tape winding machine requires certain professional knowledge and skills. Operators need to undergo special training to master the operation methods and maintenance techniques of the equipment proficiently. This not only requires spending time and effort on training but also may increase the training cost of the enterprise. Due to the relatively complex operation of the tape winding machine, if the operator operates improperly, it may lead to equipment failures, product quality problems, or even safety accidents. This requires operators to be highly focused and careful and operate strictly in accordance with the operating procedures.

[0005] Quality defects of raw materials (carbon fiber prepreg) are also the main reasons for unqualified formed products. The present invention makes improvements in automation in aspects such as improving production efficiency, increasing intelligent detection, and predicting material defects in advance.

[0006] Therefore, in view of the above technical problems, it is necessary to provide an efficient large-tension tape continuous automatic winding and defect monitoring device and an operation method thereof.

Detailed implementation manners

[0047] To enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figure 1 shown, the high-efficiency large-tension cloth tape continuous automatic winding and defect monitoring device and operation method in an embodiment of the present invention, the high-efficiency large-tension cloth tape continuous automatic winding and defect monitoring device, which includes a unwinding mechanism 1, a quality inspection mechanism 2, a secondary tension mechanism 3, a tension detection mechanism 4, a rear pressing mechanism 5, a stitching mechanism 6, a front pressing mechanism 7, a deviation rectifying mechanism 8, a film winding mechanism 9, a preheating guide roller 10, a pressing roller mechanism 11 and a hot air device 12, meets the winding requirements of different process tensions. By adding intelligent detection and predicting material defects in advance, it avoids product quality defects caused by raw material defects. By adding function modules such as deviation rectifying, stitching, hot pressing, and hot air blowing, it improves the automation level of winding, reduces manual participation, and improves work efficiency.

[0049] The bottom ends of the unwinding mechanism 1, the quality inspection mechanism 2, the secondary tension mechanism 3, the tension detection mechanism 4, the rear pressing mechanism 5, the stitching mechanism 6, the front pressing mechanism 7, the deviation rectifying mechanism 8, the film winding mechanism 9, the preheating guide roller 10, the pressing roller mechanism 11 and the hot air device 12 are all fixedly connected to the winding base 14, and realize the high-speed winding of the cloth tape through the linkage with the numerical control system.

[0050] One side end face of the unwinding mechanism 1 is fixedly connected to the quality inspection mechanism 2. A secondary tension mechanism 3 is arranged between the quality inspection mechanism 2 and the tension detection mechanism 4. On one side end face of the tension detection mechanism 4, a rear pressing mechanism 5, a stitching mechanism 6, a front pressing mechanism 7, a deviation rectifying mechanism 8 and a film winding mechanism 9 are arranged in sequence. A preheating guide roller 10 and a pressing roller mechanism 11 are arranged in sequence on the lower side end face of the film winding mechanism 9. The bottom end face of the pressing roller mechanism 11 is fixedly connected to the hot air device 12. The hot air device 12 includes a hot air nozzle 1202, and the hot air nozzle 1202 fits the tangent position of the pressing roller mechanism 11 and the mold.

[0051] Furthermore, the unwinding mechanism 1 includes a first guide roll 101, a second guide roll 102 and an unwinding air-expanding shaft 103, which are all fixedly connected to the winding unit back plate 13, and the unwinding air-expanding shaft 103 is located on the upper end surface of the first guide roll 101 and the second guide roll 102, and the quality inspection mechanism 2 is located between the first guide roll 101 and the second guide roll 102. The unwinding mechanism 1 is located at the rear end of the device and is used to generate initial tension. After the tension is generated, the cloth tape is straightened through the first guide roll 101 and the second guide roll 102 and then enters the quality inspection mechanism 2.

[0052] The quality inspection mechanism 2 is used to inspect the quality defects of the tape, including the presence or absence of metal impurities, the uniformity of the thickness of the tape, etc. When defects are found, the machine will automatically stop and send out an alarm signal.

[0053] like Figure 10 As shown, the quality inspection mechanism 2 can detect and alarm foreign objects such as metal inclusions in the raw materials of the tape. The principle is to use the magnetic field to detect metal foreign objects. The coil metal wire is energized to generate a magnetic field, and the inspected product passes through the magnetic field. By measuring the change in the magnetic field after being affected, the foreign objects mixed in can be detected, thereby reducing the generation of waste products.

[0054] like Figure 2-7 As shown, the secondary tension mechanism 3 includes a tension enhancement roll 301 and a synchronous belt conveyor 302, the tension enhancement roll 301 is connected to the synchronous belt conveyor 302, and the synchronous belt conveyor 302 is fixedly connected to one side end surface of the winding unit back plate 13. The tension detection mechanism 4 includes a tension sensor and a side plate 406, a pair of opposite end surfaces of the side plate 406 are respectively fixedly connected to the tension enhancement roll 301 and the encoder guide roll 405, a tension sensor protective cover 404 is fixedly connected to the middle end surface of the side plate 406, a tension sensor is installed in the tension sensor protective cover 404, a pair of tension sensor protective covers 404 are fixedly connected to the guide roll support 402, the guide roll support 402 is fixedly connected to the third guide roll 401, and the third guide roll 401 is connected to the knurled high head screw 403. The tension detection is performed by the tension detection mechanism 4.

[0055] The secondary tension mechanism 3 upgrades the tension twice to obtain a large process tension; the secondary tension mechanism 3 and the tension detection mechanism 4 form a closed-loop control, thereby realizing precise control of the tension, and the tension accuracy can reach ±1N when winding at a constant speed.

[0056] like Figure 8 As shown in the figure, the tension control principle is as follows: the tension is increased step by step by using two-level tension, which can effectively ensure that the unwinding and tension controller are closed-loop controlled, and the tension can reach 1500N. The tension applied to the tape can be increased step by step by using two-level tension increase, which can effectively protect the tape from fiber damage caused by the instantaneous increase in tension, and can also facilitate the precise control of tension.

[0057] The secondary tension adopts the 4Ω increasing tension amplification principle, and the total tension amplification coefficient is:

[0058] K = K1 * K2 * K3 * K4

[0059] Where Ki is the amplification coefficient of each stage.

[0060] Such as Figure 9 As shown, the single-stage amplifier uses a magnetic powder brake to apply tension. To ensure uniform tension application and prevent yarn damage caused by single-stage overshoot / undershoot, the working state parameters of each stage of the magnetic powder brake are measured online, calculated by a programmable controller, and the input current of each stage is adjusted to achieve tension distribution. The programmable controller can be adjusted manually online or communicate with the winding machine control system through the bus.

[0061] The rear pressing mechanism 5 includes a fixed seat 501, a first automatic sliding mechanism 502 and a pressing plate 503. The fixed seat 501 is fixedly connected to the top end face of the winding base 14. A pair of first automatic sliding mechanisms 502 are movably connected to one side end face of the fixed seat 501. The bottom end faces of the pair of first automatic sliding mechanisms 502 are fixedly connected to the pressing plate 503. The pressing plate 503 presses the cloth tape by the up and down movement of the first automatic sliding mechanism 502.

[0062] The front pressing mechanism 7 includes a traction mechanism 701, and the traction mechanism 701 is fixedly connected to one side end face close to the deviation rectifying mechanism 8. The front pressing mechanism 7 has a different structure from the rear pressing mechanism 5. The only difference is that a traction mechanism 701 is fixedly connected to the rear side end face of the fixed seat 501 of the front pressing mechanism 7, which can realize the sewing times. The cloth tape is pressed and fixed by the rear pressing mechanism 5 and the front pressing mechanism 7.

[0063] The sewing mechanism 6 includes a sewing machine mounting plate 605. A sewing machine head mounting plate 602 is slidably connected to the sewing machine mounting plate 605, and the sewing machine head mounting plate 602 is fixedly connected to a sewing machine head 601.

[0064] Furthermore, a cylinder is provided on the inner end face of the sewing machine mounting plate 605. A slide rail 604 and a slider 603 are provided on the outer end face of the sewing machine mounting plate 605. The cylinder drives the slider 603 to slide on the slide rail 604, thereby driving the up and down movement of the sewing machine head 601.

[0065] A sliding mechanism is installed on the bottom end face of the sewing machine mounting plate 605. The sliding mechanism drives the sewing machine mounting plate 605 to move back and forth. The bottom end face of the sliding mechanism is fixedly connected to the bottom end face of the winding base 14.

[0066] Preferably, the sliding mechanism includes a cylinder, the top of the cylinder is connected to a mounting plate, and the mounting plate is connected to the sewing machine mounting plate 605.

[0067] Specifically, when the fabric tape is being changed, the stitching mechanism 6 automatically stitches and connects the front and back fabric tapes. The stitching mechanism 6 is controlled by a servo motor, which can achieve accurate positioning and movement, and can automatically cut the thread ends, thus ensuring product quality and improving production efficiency. Compared with traditional manual sewing, it can complete a large number of sewing tasks in a short time, saving time and labor costs for the enterprise. The stitches are uniform and firm.

[0068] An automatic slide table assembly 15 is slidably connected to the top end face of the winding base 14. The automatic slide table assembly 15 includes a slide table 1501, a second automatic sliding mechanism 1502, and a deviation rectifying bracket 1503. The second automatic sliding mechanism 1502 is fixed to the winding base 14, the top end face of the second automatic sliding mechanism 1502 is fixedly connected to the slide table 1501, the top end face of the slide table 1501 is fixedly connected to the deviation rectifying bracket 1503, and the second automatic sliding mechanism 1502 drives the slide table 1501 and the deviation rectifying bracket 1503 to move, thereby driving the deviation rectifying mechanism 8 to move.

[0069] The deviation rectifying mechanism 8 is connected to the top end face of the automatic slide table assembly 15. The deviation rectifying mechanism 8 is installed on the pressure roller mechanism 11 through one side end face of the slide table 1501. The deviation rectifying mechanism 8 includes a photoelectric position sensor and a plurality of deviation rectifying rollers 801. A plurality of pairs of deviation rectifying rollers 801 are arranged parallel to each other. That is, the deviation rectifying mechanism 8 is installed on the pressure roller mechanism 11 and is relatively stationary with the pressure roller mechanism 11 to ensure the deviation rectifying accuracy of the fabric tape. The deviation rectifying mechanism 8 adopts a double-parallel proportional roller closed-loop control. The deviation rectifying mechanism 8 mainly includes: a photoelectric position sensor, a driving motor, a driver, and a controller. The deviation rectifying mechanism 8 uses a photoelectric position sensor to detect the edge position of the fabric tape, sends the measured position error signal to the controller, and after being judged and processed by the control unit, controls the driving motor to correct the fabric tape at the deviated position to the correct position to achieve the automatic deviation rectifying function. After being detected by a special detection device, when the material linear velocity is 3000 m / min and the original deviation is in a steady state, the control accuracy of the deviation rectifying system itself can reach up to 0.08 - 0.1 mm. Therefore, the fabric tape deviation rectifying accuracy can be guaranteed within 0.5 mm, the deviation rectifying swing angle range is ±5°, and it has the function of deviating fabric tapes with a deviation rectifying width range of 10 - 200 mm. It has the deviation rectifying function on either the left or right side of the fabric tape roll, and it is convenient to switch the deviation rectifying device to independent control. It is driven by a servo electric cylinder to swing left and right for adjustment, and has an over-travel protection function and a liquid crystal Chinese menu display

[0070] The film collecting mechanism 9 includes a permanent magnet torque motor 901, which is fixedly connected to one side end face of the automatic sliding table assembly 15. The permanent magnet torque motor 901 is connected to a plurality of tiles 902. One side end faces of the plurality of tiles 902 are all connected to hinges 904, and a plurality of hinges 904 are all connected to handles 903. The film collecting mechanism 9 is located on the upper side end face of the preheating guide roller 10. By driving the plurality of tiles 902 to rotate through the permanent magnet torque motor 901, the isolation film is wound, and the isolation film between the cloth belts is collected.

[0071] The hot air device 12 includes a hot air system 1201 and a hot air rod assembly 1203. One side end face of the hot air system 1201 is fixedly connected to the hot air rod assembly 1203, and the hot air rod assembly 1203 is fixedly connected to one side end face of the automatic sliding table assembly 15. The hot air device 12 is located below the pressure roller mechanism 11, and its angle and position can be adjusted arbitrarily. Align the air outlet of the hot air nozzle 1202 with the tangent position of the pressure roller mechanism 11 and the mold to complete the preheating and softening before the cloth belt is pressed.

[0072] Among them, an electric heating roller protective cover 1001 is installed on the upper side end face of the preheating guide roller 10 to protect the preheating guide roller 10 through the electric heating roller protective cover 1001. The preheating guide roller 10 can preheat and soften the cloth belt to increase its viscosity, so that the cloth belts fit more closely and firmly when wound. Under the action of the air cylinder, the pressure roller mechanism 11 applies a pressing force to the cloth belt and the mold part to squeeze out the bubbles, making the winding effect better.

[0073] As Figure 11 shown. An operation method of an efficient large-tension cloth belt continuous automatic winding and defect monitoring device includes the following steps;

[0074] S1. Unwinding: Generate an initial tension through the unwinding mechanism 1;

[0075] S2. Cloth belt defect detection: After the tension is generated, through the first guide roller 101, the second guide roller 102 and the unwinding air shaft 103, the cloth belt is straightened and then enters the quality inspection mechanism 2 for inspection to detect the quality defects of the cloth belt, including whether there are metal impurities, the uniformity of the cloth belt thickness, etc. When a defect is found, the machine will automatically stop and send an alarm signal;

[0076] S3. Tension secondary upgrade: After the quality inspection mechanism 2 detects no errors, the cloth belt enters the secondary tension mechanism 3 to upgrade the tension for the second time to obtain a large process tension. The secondary tension mechanism 3 and the tension detection mechanism 4 form a closed-loop control, so as to realize the precise control of the tension and detect the tension;

[0077] S4. Sewing: The rear pressing mechanism 5 and the front pressing mechanism 7 press the cloth belt front and back. The cloth belt is tractioned by the traction mechanism 701 for double-seam sewing. When the cloth belt is changed, the sewing mechanism 6 automatically sews and connects the front and back cloth belts.

[0078] S5. Deviation correction: At the same time, deviation correction is carried out through the deviation correction mechanism 8 to correct the position of the cloth tape.

[0079] S6. Preheat and soften the cloth tape: The cloth tape is preheated through the preheating guide roller 10, and the separation film between the cloth tapes is collected by the film collecting mechanism 9.

[0080] S7. Press and wind the cloth bag onto the mold: After the cloth tape is preheated through the preheating guide roller 10, it enters the pressure roller mechanism 11 and finally winds onto the mold. At the same time, the cloth tape is preheated and softened before being press-connected through the hot air device 12.

[0081] The present invention has the following advantages;

[0082] The modular design of each functional component is more conducive to combination and matching, and is convenient for maintenance.

[0083] By adopting hierarchical tension closed-loop control, high-precision winding with large tension can be achieved, and the tension fluctuation is < ±1 N.

[0084] Functions such as automatic sewing, deviation correction, and automatic film collection are adopted in the module, and winding automation can be realized.

[0085] The pressure roller adopts a quick-change method and is locked by a cylinder, and automatic roller change can be realized.

[0086] The quality inspection mechanism can detect the quality defects of raw materials, ensure product quality, and increase economic benefits.

[0087] Before the pressure roller, a heating guide roller is used for preheating, and pre-softening can improve the winding quality.

[0088] The position-adjustable hot air mechanism can heat the tangent line of the pressure roller and the mold to improve the bonding firmness.
