[0041] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0042] A multi-layer material lamination production line, referring to Figure 1 There are a starting station and an ending station. The multi-layer material laminating production line includes a transport device 3, a film laminating device 2, and a transmission device 4. Multiple transport devices 3 are arranged in sequence along the X-axis direction, and multiple film laminating devices 2 are arranged. Multiple film laminating devices 2 are arranged in a one-to-one correspondence with multiple transport devices 3. Specifically, the starting station is equipped with one of the above-mentioned film laminating devices 2 and one of the above-mentioned transport devices 3, and the ending station is equipped with one of the above-mentioned film laminating devices 2 and one of the above-mentioned transport devices 3. Several transport devices 3 and several film laminating devices 2 are arranged between the starting and ending stations. One of the above-mentioned transmission devices 4 is arranged between adjacent film laminating devices 2.

[0043] Reference Figure 2 The transport device 3 includes a transport platform 31, a first linear guide 32, and a rotating member (not shown in the figure). The rotating member is fixedly connected to the output end of the first linear guide 32, and the transport platform 31 is fixedly connected to the output end of the rotating member. In this embodiment, the multi-layer material bonding production line also includes a working platform 6. Multiple first linear guides 32 are fixedly arranged on the working platform 6 along the X-axis direction. Each first linear guide 32 has a starting end and an ending end. The starting end is the end of the first linear guide 32 close to the starting station, and the ending end is the end of the first linear guide 32 close to the ending station. The operation of the first linear guide 32 drives the transport platform 31 to slide along the X-axis direction, and the operation of the rotating member drives the transport platform 31 to rotate in the horizontal direction. In this embodiment, each rotation is 90°. In other embodiments, the rotation angle can be adjusted according to actual needs and can be any other angle such as 45°, 60°, etc.

[0044] In this embodiment, the rotating member is a motor. In other embodiments, the rotating member may also be other structures that can drive the transport platform 31 to rotate.

[0045] In this embodiment, four film laminating devices 2 are used as an example to illustrate the specific solution of this application. In this embodiment, carbon fiber material 11 is used as the product material. Other materials can also be used in other embodiments. The four film laminating devices 2, from the starting station to the ending station, are named first film laminating device 21, second film laminating device 22, third film laminating device 23, and fourth film laminating device 24, respectively. The four transport platforms 31 are named first transport platform 311, second transport platform 312, third transport platform 313, and fourth transport platform 314, respectively.

[0046] The first film laminating device 21 lays the first layer of carbon fiber material 11 on the first transportation platform 311. After the first transportation platform 311 moves to the termination end corresponding to the first linear guide rail 32, the second transportation platform 312 moves to the starting end corresponding to the first linear guide rail 32. Through the transmission device 4 between the first film laminating device 21 and the second film laminating device 22, the carbon fiber material 11 on the first transportation platform 311 is transported to the second transportation platform 312. The second transportation platform 312 first moves to the termination end corresponding to the first linear guide rail 32, and the rotating member drives the second transportation platform 312 to rotate 90°, so that the first layer of carbon fiber material 11 on the second transportation platform 312 rotates 90 degrees. Then the second transportation platform 312 is moved to correspond to the feeding position of the second film laminating device 22. At this time, the film laminating device 2 lays the second layer of carbon fiber material 11 on the first layer of carbon fiber material 11. In other embodiments, the second transportation platform 312 may not rotate 90°, as long as it is ensured that the textures of several layers of carbon fiber materials 11 are alternately vertical and horizontal in sequence.

[0047] After the laying of the second layer of carbon fiber material 11 is completed, the second transportation platform 312 moves to the termination end corresponding to the first linear guide rail 32, and then the driving member drives the second transportation platform 312 to rotate 90° in the reverse direction to reset the second transportation platform 312. Then, through the transmission device 4 between the second film laminating device 22 and the third film laminating device 23, the two layers of carbon fiber materials 11 are moved to the third transportation platform 313. The third transportation platform 313 drives the two layers of carbon fiber materials 11 to the feeding position of the third film laminating device 23. At this time, the third film laminating device 23 lays the third layer of carbon fiber material 11 on the second layer of carbon fiber material 11. At this time, it is also necessary to ensure that the texture of the third layer of carbon fiber material 11 intersects with the texture of the second layer of carbon fiber material 11. If the texture directions of the second layer of carbon fiber material 11 and the third layer of carbon fiber material 11 are the same when the third transportation platform 313 is not rotated, then first move the third transportation platform 313 to the termination end corresponding to the first linear guide rail 32, drive the third moving platform to rotate 90° through the rotating member, and then move back to the feeding position of the third film laminating device 23 to lay the third layer of carbon fiber material 11, ensuring that each layer of carbon fiber material 11 is alternately vertical and horizontal in sequence.

[0048] If a product made of only four layers of carbon fiber material 11 is required, then through the transmission device 4 between the third film laminating device 23 and the fourth film laminating device 24, the three layers of carbon fiber materials 11 are moved to the fourth transportation platform 314, and the fourth film laminating device 24 lays the fourth layer of carbon fiber material 11 on the third layer of carbon fiber material 11 and rotates the fourth transportation platform 314 to ensure that the textures on the third layer of carbon fiber material 11 and the fourth layer of carbon fiber material 11 are alternately vertical and horizontal.

[0049] If a product made of carbon fiber material 11 with more than four layers is required, after the third layer of carbon fiber material 11 is pasted, the third transport platform 313 moves to the starting end of the corresponding first linear guide 32, and through the transport device 4 between the third film pasting device 23 and the second film pasting device 22, the three-layer carbon fiber material 11 is transported to the second transport platform 312, and the three-layer carbon fiber material 11 is moved to the loading position of the second film pasting device 22 by the second transport platform 312. The second film pasting device 22 lays the fourth layer of carbon fiber material 11 on the third layer of carbon fiber material 11, and through the rotation of the second transport platform 312, it is ensured that the texture of the fourth layer of carbon fiber material 11 intersects with that of the third layer of carbon fiber material 11 vertically and horizontally. At this time, if a product made of five-layer carbon fiber material 11 is required, after transporting the four-layer carbon fiber material 11 to the third transport platform 313 and then to the fourth transport platform 314, the fifth layer is laid by the fourth film pasting device 24. If more layers are required, the carbon fiber material 11 is repeatedly transported on the second transport platform 312 and the third transport platform 313, and the second film pasting device 22 and the third film pasting device 23 are repeatedly used for laying.

[0050] Through the structure and operation mode of the above production line, only four film pasting devices 2 are set to realize the laying of multiple layers of carbon fiber material 11. According to actual needs, several layers of carbon fiber material 11 can be laid to realize the production of carbon fiber material 11 products with different numbers of layers and increase its applicability.

[0051] Refer to Figure 3 , the transport device 4 includes a second linear guide 41, a third linear guide 43, a first mounting bracket 44 and a first suction cup 45. The second linear guide 41 is arranged between two adjacent film pasting devices 2, and both ends of the second linear guide 41 are fixedly connected to the two film pasting devices 2 respectively. In this embodiment, in order to further increase the stability of the second linear guide 41, a bracket 46 is fixedly connected to the working platform 6, and the second linear guide 41 is further supported by the bracket 46.

[0052] The third linear guide 43 is fixedly connected to the output end of the second linear guide 41, and the first mounting bracket 44 is fixedly connected to the output end of the third linear guide 43. Through the operation of the second linear guide 41, the first mounting bracket 44 is driven to move along the X-axis direction. The first suction cup 45 is fixedly installed on the first mounting bracket 44. The mounting bracket is driven by the third linear guide 43 to move towards the carbon fiber material 11, and then the carbon fiber material 11 is adsorbed by the first suction cup 45 to realize the position transfer of the carbon fiber material 11.

[0053] In this embodiment, a plurality of first suction cups 45 are provided. The plurality of first suction cups 45 are all fixed on the first mounting frame 44, and the first suction cups 45 are pneumatic vacuum suction cups. By pumping air with an air pump, the adsorption and grasping of the carbon fiber material 11 are realized.

[0054] Referring to Figure 2 and Figure 3 , the film pasting device 2 includes a frame 25, a loading roller 26, an upper film winding roller 27, a rear film winding roller 28, a driving motor (not shown in the figure), and a film cutting assembly 29. The frame 25 is fixed on the working platform 6. The loading roller 26, the upper film winding roller 27, and the rear film winding roller 28 are all arranged along the Y-axis and are all rotatably connected to the frame 25. Since the carbon fiber material 11 needs to be protected during storage, an upper film 12 is covered on the upper surface of the carbon fiber material 11, and a rear film 13 is covered on the rear surface of the carbon fiber material 11. The loading roller 26 is wound with multiple layers of carbon fiber materials 11 covered with the upper film 12 and the rear film 13. The upper film 12 is separated from the carbon fiber material 11 and wound on the upper film winding roller 27. The rear film 13 is separated from the carbon fiber material 11 and wound on the rear film winding roller 28. There are two driving motors. The output end of one driving motor is fixedly connected to the end of the upper film winding roller 27, and the output end of the other driving motor is fixedly connected to the end of the rear film winding roller 28. By the operation of the two driving motors, the upper film winding roller 27 and the rear film winding roller 28 are respectively driven to rotate, so as to realize the winding of the upper film 12 by the upper film winding roller 27 and the winding of the rear film 13 by the rear film winding roller 28.

[0055] Moreover, there is a loading position for the film pasting device 2. The loading position is located between the starting end and the terminating end of the first linear guide 32. The upper film winding roller 27 is arranged between the terminating end of the first linear guide 32 and the loading position, and the rear film winding roller 28 is arranged between the starting end of the first linear guide 32 and the loading position. When it is necessary to lay the carbon fiber material 11 on the transportation platform 31, first move the transportation platform 31 to the loading position. At this time, the two driving motors operate to drive the upper film winding roller 27 and the rear film winding roller 28 to rotate. By the rotation of the upper film winding roller 27, the upper film 12 is wound. By the rotation of the rear film winding roller 28, the rear film 13 is wound. By pulling the upper film 12, the loading roller 26 is driven to rotate, so that the carbon fiber material 11 is laid on the transportation platform 31. At this time, the carbon fiber material 11 is cut off by the film cutting assembly 29, and the laying of one layer of the carbon fiber material 11 can be realized.

[0056] Furthermore, a plurality of tension rollers 214 are rotatably arranged on the frame 25. The upper film 12, the rear film 13, and the carbon fiber material 11 are respectively tensioned by the plurality of tension rollers 214 to ensure the stable transmission of the upper film 12, the rear film 13, and the carbon fiber material 11.

[0057] The film cutting assembly 29 is arranged at the material cutting position. The film cutting assembly 29 includes a fourth linear guide rail 291 and a film cutting knife 292. The fourth linear guide rail 291 is arranged along the Y-axis direction (i.e., along the axis direction of the feeding roller 26) and is fixedly connected to the machine frame 25. The film cutting knife 292 is fixedly connected to the output end of the fourth linear guide rail 291. The fourth linear guide rail 291 drives the film cutting knife 292 to slide along the Y-axis, so as to cut the carbon fiber material 11 and realize the control of the length of the carbon fiber material 11 laid on the transportation platform 31.

[0058] Furthermore, the film pasting device 2 further includes a film pressing assembly 210. The film pressing assembly 210 presses several layers of carbon fiber materials 11 together to make the several layers of carbon fiber materials 11 fit tightly and be laid flat. The film pressing assembly 210 includes a second mounting frame 211, a telescopic member 212, and a film pressing roller 213. The telescopic member 212 is fixedly connected to the machine frame 25 and can telescopically move in a direction close to or away from the transportation platform 31, that is, the telescopic member 212 is arranged along the Z-axis direction. The second mounting frame 211 is fixedly connected to the output end of the telescopic member 212. The film pressing roller 213 is arranged along the Y-axis direction and is rotatably connected to the second mounting frame 211. The film pressing assembly 210 is arranged between the feeding assembly and the end of the first linear guide rail 32 and is located above the transportation platform 31. During the process of the feeding roller 26 rotating for feeding, the telescopic member 212 extends, so that the film pressing roller 213 presses on the carbon fiber material 11 to flatten the carbon fiber material 11. After the carbon fiber material 11 is cut by the film cutting knife 292, the transportation platform 31 can move towards the starting end of the first linear guide rail 32, so that the pressing roller flattens the carbon fiber material 11 again, further ensuring the flatness of the carbon fiber material 11 and the tightness of the fit of the multi-layer carbon fiber materials 11.

[0059] Refer to Figure 4 As shown in the figure, the multi-layer material laminating production line further includes a blanking device 5. The blanking device 5 is arranged at the end station and is used for blanking the multi-layer carbon fiber material 11 products. The blanking device 5 includes a fifth linear guide rail 51, a sixth linear guide rail 52, a third mounting frame 53, and a second suction cup 54. The fifth linear guide rail 51 is fixed on the machine frame 25 at the end station. The sixth linear guide rail 52 is fixedly connected to the output end of the fifth linear guide rail 51 and is arranged along the Z-axis direction. The third mounting frame 53 is fixed on the output end of the sixth linear guide rail 52. The fifth linear guide rail 51 drives the third mounting frame 53 to move along the X-axis direction, and the sixth linear guide rail 52 drives the third mounting frame 53 to move along the Z-axis direction. The second suction cup 54 is fixedly installed on the third mounting frame 53. The second suction cup 54 adsorbs the completed multi-layer carbon fiber material 11 products and transports them away through the fifth linear guide rail 51, thereby completing the blanking.
