[0054] The present invention provides a prepreg slitting and drilling production line, which is suitable for the application scenario of slitting and drilling prepregs in roll form, and can effectively solve the problem that the existing prepreg cutting and drilling equipment can only perform cutting and drilling operations on one roll of prepreg, resulting in low production efficiency.

[0055] See also Figure 1 The prepreg slitting and drilling production line provided in this embodiment includes a coil release module 1, a slitting unit 2, a pre-drilling stacking module 3, a drilling module 4, a storage silo, and a transport vehicle 5.

[0056] See also Figure 2 The coil release module 1 includes at least two unwinding rolls 101 for releasing a whole sheet of prepreg, and an automatic deviation correction device for correcting the deviation of each of the whole sheets of prepreg; wherein the unwinding rolls 101 are arranged in sequence from top to bottom. The slitting unit 2 is used to slit each of the whole sheets of prepreg to obtain a plurality of flatly arranged post-cut lamination units; wherein each of the post-cut lamination units includes a plurality of stacked rectangular prepregs.

[0057] Specifically, the specific structure of the automatic deviation-correcting device is prior art and will not be described in detail in this embodiment.

[0058] The pre-drilling stacking module 3 is used to stack a number of the post-cut stacking units to form a pre-drilling stacking unit; the drilling module 4 is used to drill holes in each of the pre-drilling stacking units to obtain a post-drilling stacking unit.

[0059] In the prepreg cutting and drilling production line provided by the present invention, the coil release module 1 is provided with at least two unwinding rolls 101. When a single roll of prepreg needs to be cut and drilled, only one of the unwinding rolls 101 needs to be loaded; when multiple rolls of prepreg need to be cut and drilled, only multiple unwinding rolls 101 need to be loaded.

[0060] After loading the coil release module 1, each unwinding roll 101 releases a whole prepreg synchronously, and each of the whole prepregs is stacked from top to bottom. At this time, the slitting unit 2 performs slitting to slit each of the whole prepregs into a plurality of flatly arranged stacked units after slitting; the slitting unit 2 can perform synchronous slitting on a plurality of the whole prepregs in each slitting operation, thereby improving the slitting efficiency;

[0061] After the cutting is completed, the pre-drilling stacking module 3 stacks several of the cut stacking units to form a pre-drilling stacking unit, and then the drilling module 4 drills each of the pre-drilling stacking units; the drilling module 4 can drill multiple rectangular semi-cured sheets each time, further improving the drilling efficiency.

[0062] Therefore, the prepreg cutting and drilling production line provided by the present invention can effectively solve the problem that the existing prepreg cutting and drilling equipment can only perform cutting and drilling operations on one roll of prepreg, resulting in low production efficiency.

[0063] See also Figure 2 In this embodiment, the slitting unit 2 includes a slitting and feeding platform 201 located between the coil release module 1 and the pre-drilling stacking module 3, a plurality of longitudinal cutting rollers 202 located above the slitting and feeding platform 201, and a transverse cutter 203 located between each of the longitudinal cutting rollers 202 and the pre-drilling stacking module 3.

[0064] The slitting and feeding platform 201 receives the prepreg from the coil release module 1, the longitudinal cutting roller 202 cuts the prepreg longitudinally, and the transverse cutting knife 203 cuts the prepreg transversely to complete the slitting operation. Accurate slitting improves material utilization and reduces waste. The efficient cutting process shortens the production cycle and increases output.

[0065] Optionally, a plurality of laser preheating components 204 are provided above and / or below the slitting and feeding platform 201. The laser preheating components 204 include a plurality of laser heads 2041 and a laser linear drive mechanism 2042 for driving the laser heads 2041 to reciprocate along the width direction of the entire semi-cured sheet.

[0066] The laser head 2041 can perform rapid heating at a single point, and the laser linear drive mechanism 2042 drives the laser head 2041 to reciprocate along the width direction of the entire semi-cured sheet in order to improve the heating uniformity.

[0067] Optionally, an infrared preheating lamp 205 is provided above and / or below the slitting and feeding platform 201 .

[0068] The laser preheating component 204 or the infrared preheating lamp 205 can preheat the prepreg, which effectively reduces the PP powder, PP silk, white edges, etc. generated during the PP cutting process, so that glass fiber dust will not be generated at the edge of the cut, achieving effective edge sealing.

[0069] See also Figure 3 and Figure 4 A material receiving plate 6 is provided at one end of the pre-drilling stacking module 3 close to the cutting unit 2, wherein the material receiving plate 6 has a vertical state and an inclined state; the bottom of the pre-drilling stacking module 3 is connected to a hydraulic linear drive mechanism 7 for driving the pre-drilling stacking module 3 to approach or move away from the cutting unit 2.

[0070] When slitting and drilling are performed on multiple rolls of semi-cured sheets, the receiving plate 6 is in a vertical state, and the hydraulic linear drive mechanism 7 drives the pre-drilling stacking module 3 to approach the slitting unit 2 so as to complete the entire slitting and drilling process; when only a single roll of semi-cured sheets is to be slid and drilled, the hydraulic linear drive mechanism 7 can drive the pre-drilling stacking module 3 to move a certain distance away from the slitting unit 2, and then switch the receiving plate 6 to an inclined state. At this time, the rectangular semi-cured sheets after slitting will fall directly into the receiving plate 6. After a period of time, the materials in the receiving plate 6 are manually transported to other locations for unified drilling, which is more efficient.

[0071] The flexible adjustment mechanism enables the production line to adapt to the needs of different production volumes, improves the convenience of operation, optimizes the material collection and handling process, and improves production efficiency.

[0072] See also Figure 3 In this embodiment, the pre-drilling stacking module 3 includes a first stacking robot 301 and a second stacking robot 302 for stacking the post-cut stacking units to form a pre-drilling stacking unit, a clamping assembly 303 for clamping and pressing the pre-drilling stacking unit, and a drilling feed linear drive mechanism 304 for driving the clamping assembly 303 to reciprocate between the pre-drilling stacking module 3 and the drilling module 4.

[0073] The first stacking robot 301 and the second stacking robot 302 carry out alternate transport to stack the post-cut stacking units into pre-drilling stacking units, and the clamping assembly 303 presses each of the pre-drilling stacking units from the edge position to ensure stability, and then the drilling feed linear drive mechanism 304 delivers the clamped pre-drilling stacking units to the drilling module 4.

[0074] See also Figure 5 In this embodiment, the drilling module 4 includes a drill head unit 401, a drilling platform 402 for placing the pre-drilling stacking unit, a pre-drilling manipulator 403 for transporting the pre-drilling stacking unit from the pre-drilling stacking module 3 to the drilling platform 402, a post-drilling manipulator 404 for moving the post-drilling stacking unit away from the drilling platform 402, and a lifting U-shaped platform 405 for receiving the post-drilling stacking unit.

[0075] Furthermore, the drilling module 4 further includes a drilling entry plate 406, a cover plate cylinder 407, a driving belt 408, and a belt motor 409. The drilling entry plate 406 is higher than the drilling platform 402; the driving end of the cover plate cylinder 407 is connected to the drilling entry plate 406, and is used to drive the drilling entry plate 406 to move downward to press the pre-drilling stacking unit or move upward to release the post-drilling stacking unit; the cover plate cylinder 407 is installed on the driving belt 408; the belt motor 409 drives the driving belt 408 to rotate, so that the drilling entry plate 406 moves horizontally to the top of the drilling platform 402, or moves to the side of the drilling platform 402.

[0076] Optionally, the number of the drill head unit 401 and the drilling entry plate 406 are both two, wherein the cover plate cylinder 407 corresponding to one of the drilling entry plates 406 is connected to the front half of the driving belt 408, and the cover plate cylinder 407 corresponding to the other drilling entry plate 406 is connected to the rear half of the driving belt 408, so that the two drilling entry plates 406 are synchronously moved to the top of the drilling platform 402, or synchronously moved to the side of the drilling platform 402.

[0077] At the beginning, the drilling entry plate 406 is located beside the drilling platform 402, the pre-drilling manipulator 403 places the pre-drilling stacking unit on the drilling platform 402, the belt motor 409 and the driving belt 408 drive the drilling entry plate 406 to move to just above the drilling platform 402, and then the cover plate cylinder 407 drives the drilling entry plate 406 to move downward to press the pre-drilling stacking unit, and then the drill head unit 401 can directly penetrate the drilling entry plate 406 to drill the pre-drilling stacking unit.

[0078] In this embodiment, the drilling entry plate 406 is a consumable part and needs to be replaced after drilling multiple times. Using the drilling entry plate 406 to press before drilling can improve the accuracy and consistency of the drilling position and size, and can also reduce burrs and other defects caused by material deviation.

[0079] The storage silo is used to store the post-drilling stacked units that are stacked in an offset manner, and the transport vehicle 5 is used to transport the post-drilling stacked units from the lifting U-shaped platform 405 to the storage silo.

[0080] A carrier is placed on the lifting U-shaped platform 405 in advance, and then the post-drilling manipulator 404 can move each post-drilling stacking unit away from the drilling platform 402 and stack them on the carrier. Optionally, in order to facilitate the later removal, the post-drilling manipulator 404 can perform an appropriate left offset in the horizontal direction each time it stacks materials to achieve staggered stacking.

[0081] As the stacking height of materials on the carrier gradually increases, the lifting U-shaped platform 405 gradually descends. When the stacking height reaches the requirement, the lifting U-shaped platform 405 continues to descend, and the carrier together with the materials can be placed on the transport vehicle 5, which will be transported to the storage silo for storage.

[0082] Optionally, an AGV trolley may be used for automatic transportation, or a trolley may be used for manual transportation, which is not limited in the present invention.

[0083] In summary, the prepreg slitting and drilling production line provided in this embodiment has the following advantages:

[0084] ①The production line design can process single roll and multiple rolls of prepreg at the same time, which improves the adaptability and flexibility of the equipment and can meet different production needs;

[0085] ② The use of laser preheating components 204 and infrared preheating lamps 205 reduces the PP powder, PP silk, white edges, etc. generated during the PP cutting process, so that glass fiber dust will not be generated on the edge of the cut, achieving effective edge sealing and improving cutting quality;

[0086] ③ The design of the drilling cover plate 406 ensures the accuracy and consistency of drilling and reduces the generation of defective products;

[0087] ④ The use of the lifting U-shaped platform 405 and the transport vehicle 5 makes the stacking and handling of materials more convenient, thus optimizing the production process;
