[0001] The present application relates to the technical field of carbon fiber manufacturing equipment, and in particular to an automatic threading device and a carbon fiber production line. Background Art

[0002] Carbon fiber has excellent properties such as light weight, high strength, high modulus, fatigue resistance and corrosion resistance. It is mainly used as a reinforcing material for composite materials and is widely used in aerospace, military industry, new energy, transportation, sports products and other fields.

[0003] In the carbon fiber production process, the precursor needs to be placed on a withdrawal rack for withdrawal before carbonization. Currently, this transfer step is mainly performed manually. During operation, it is easy to accidentally touch the precursor, causing damage, and there is a risk of the precursor barrel falling due to improper fixing. In addition, manual operation is time-consuming and labor-intensive, which is not conducive to improving production efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of this application is to provide an automatic wire-loading device and a carbon fiber production line to reduce the risk of damage to the original wire, improve the yield rate, and improve production efficiency.

[0005] In a first aspect, an embodiment of the present application provides an automatic wire-winding device, comprising a raw wire drum, a wire fork device, and a wire withdrawal device. The raw wire drum is used to wind the raw wire, and a first positioning device is provided in the raw wire drum for transmitting a position signal. The wire fork device comprises a wire fork shaft, a controller connected to the wire fork shaft and capable of controlling the movement of the wire fork shaft, and a push rod assembly sleeved on one end of the wire fork shaft and capable of sliding telescopically along the wire fork shaft. A second positioning device is provided in the wire fork shaft for receiving a position signal; the controller processes the received position signal of the raw wire drum and controls the wire fork shaft to coaxially dock with the raw wire drum so as to sleeve the raw wire drum on the wire fork shaft. The wire withdrawal device comprises a wire withdrawal shaft, and a third positioning device is provided in the wire withdrawal shaft for transmitting a position signal; the controller processes the received position signal of the wire fork shaft and controls the wire fork shaft sleeved with the raw wire drum to coaxially dock with the wire withdrawal shaft, and the push rod assembly slides along the wire fork shaft to transfer the raw wire drum to the wire withdrawal shaft.

[0006] In the above technical solution, the automatic wire-loading equipment provided by the present application sets a first positioning device in the raw wire tube, a second positioning device in the cross-wire device, and a third positioning device in the wire withdrawal device, so that the cross-wire device can automatically align with the raw wire tube to complete wire removal, and automatically align with the cross-wire shaft to complete wire loading, thereby realizing the automation of the raw wire tube wire loading operation, reducing the risk of raw wire damage during the transportation of the raw wire tube, improving the yield rate, and improving production efficiency.

[0007] In a possible implementation, the first positioning device and the third positioning device are both electromagnetic positioning system transmitters, and the second positioning device is an electromagnetic positioning system receiver.

[0008] In the above technical solution, the first, second, and third positioning devices are all electromagnetic induction positioning devices, which are low-cost, compact, and lightweight. Their positioning is not restricted by line of sight and offers a flexible range of motion. The electromagnetic positioning system transmitter precisely transmits position signals, and the electromagnetic positioning system receiver correspondingly receives the sensed position signals.

[0009] In a possible implementation, the signal sensing range of the second positioning device is 0 to 50 centimeters.

[0010] In the above technical solution, the second positioning device can accurately sense the position signal within a range of 0 to 50 cm. When in use, it is only necessary to move the fork wire device to a range of 50 cm from the original wire drum or the wire withdrawal device to accurately receive the position signal.

[0011] In one possible implementation, the first positioning device is annular, and the raw yarn drum is hollow cylindrical. The outer diameter of the first positioning device is equal to the diameter of the raw yarn drum, and the inner diameter of the first positioning device is larger than the diameters of the cross-wire shaft and the wire withdrawal shaft. The diameter of the first positioning device is perpendicular to the length of the raw yarn drum. By installing the first positioning device horizontally within the raw yarn drum, the cross-wire shaft and the wire withdrawal shaft can pass through the first positioning device, thereby not affecting the cross-wire shaft's wire extraction and the wire withdrawal shaft's wire feeding.

[0012] In a possible implementation, the fork wire device also includes a frame, one end of the fork wire shaft is movably connected to the frame, and the controller is connected to the frame and controls the fork wire shaft to move linearly along the frame.

[0013] In the above technical solution, by movably connecting the fork wire shaft to the frame, the controller can control the fork wire shaft to move linearly up and down along the frame, thereby achieving coaxial docking with the original wire drum or the wire withdrawal shaft.

[0014] In one possible implementation, the push rod assembly is disposed at one end of the fork shaft near the frame. The push rod assembly includes a drive motor and a reciprocating telescopic annular connecting rod, which is sleeved on the fork shaft and can be telescopically slid along the fork shaft under the drive of the drive motor.

[0015] In the above technical solution, a telescopic and sliding push rod assembly is provided at one end of the wire fork shaft, so that the original wire tube can be pushed from the wire fork shaft to the wire withdrawal shaft to complete the wire winding.

[0016] In a possible implementation, the wire withdrawal device further includes a wire withdrawal rack, one end of the wire withdrawal shaft is connected to the wire withdrawal rack, and the wire withdrawal rack is provided to facilitate fixing the position and height of the wire withdrawal shaft.

[0017] In a possible implementation, the height direction of the wire withdrawal rack is perpendicular to the length direction of the wire withdrawal shaft, which can facilitate wire feeding and prevent the original wire drum from slipping.

[0018] In one possible implementation, the wire crossbar device includes multiple wire crossbar shafts, which are sequentially connected to the frame at intervals. The wire withdrawal device includes multiple wire withdrawal shafts, which are sequentially connected to the wire withdrawal frame at intervals. The arrangement of the multiple wire crossbar shafts on the frame is the same as the arrangement of the multiple wire withdrawal shafts on the wire withdrawal frame. By controlling the multiple wire crossbar shafts and the wire withdrawal shafts to be arranged in the same manner, multiple bobbins of raw wire can be transferred simultaneously, further improving production efficiency.

[0019] In a second aspect, an embodiment of the present application provides a carbon fiber production line, comprising the above-mentioned automatic threading device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] In the description of the present invention, it should be noted that if the terms "upper", "lower", "left", "right", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0030] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0031] In the process of producing carbon fiber, the precursor needs to be carbonized, and before the carbonization treatment, the precursor tube must first be transferred to the wire withdrawal rack for wire withdrawal. At present, the transfer and threading operation of the precursor tube is mainly carried out manually. First, the fork wire shaft is aligned with the precursor tube and inserted into the precursor tube. The precursor tube is transferred to the side of the wire withdrawal shaft through the fork wire shaft, and then the precursor tube on the fork wire shaft is transferred to the wire withdrawal shaft for wire withdrawal. During the transfer process, the fork wire shaft needs to be manually aligned with the precursor tube or the wire withdrawal shaft, which is easy to misalign, easily touch or cause the precursor tube to fall and be damaged, affecting the product yield. In addition, manual operation is time-consuming and labor-intensive, which is not conducive to improving production efficiency.

[0032] Based on the above considerations, the present invention provides an automatic feeding device and a carbon fiber production line including the automatic feeding device. Figures 1 to 5 The automated wire-winding equipment includes a raw wire drum 10, a wire cross device 20 and a wire withdrawal device 30. The raw wire drum 10 is used to wind the raw wire 11, and the wire cross device 20 is used to transfer the raw wire drum 10 to the wire withdrawal device 30 to withdraw the raw wire 11.

[0033] See Figure 1 A first positioning device 12 is provided in the raw silk drum 10 and can be used to transmit a position signal.

[0034] In some embodiments, the first positioning device 12 is an electromagnetic positioning system transmitter, which can accurately send a position signal of the raw silk drum 10 through electromagnetic induction.

[0035] In the embodiment of the present application, the raw yarn drum 10 is generally hollow cylindrical, and the first positioning device 12 is generally annular. The outer diameter of the first positioning device 12 is generally equal to the diameter of the raw yarn drum 10. The length direction of the raw yarn drum 10 is defined as the first direction A, and the height direction is defined as the second direction B. The first positioning device 12 is installed transversely within the raw yarn drum 10. That is, within the raw yarn drum 10, the diameter extension direction of the first positioning device 12 (i.e., the second direction B) is perpendicular to the length direction of the raw yarn drum 10 (i.e., the first direction A).

[0036] See Figure 2 and Figure 3 The fork wire device 20 includes a frame 21, a fork wire shaft 22, a second positioning device 23, a push rod assembly 24, and a controller 25. One end of the fork wire shaft 22 is movably connected to the frame 21. The second positioning device 23 is located within the fork wire shaft 22 and is used to receive position signals. The push rod assembly 24 is located at one end of the fork wire shaft 22 near the frame 21 and can slide telescopically along the fork wire shaft 22. The controller 25 is located on the frame 21 and can process the received position signals and control the fork wire device 20 to move horizontally up and down and control the fork wire shaft 22 to move linearly up and down along the frame 21 to align with the original silk drum 10 to complete the silk extraction.

[0037] In some embodiments, the second positioning device 23 is an electromagnetic positioning system receiver that can receive position signals. The signal sensing range of the second positioning device 23 is 0 to 50 centimeters. In other words, the second positioning device 23 can receive position signals within a range of 0 to 50 centimeters in diameter.

[0038] As can be understood, the electromagnetic positioning device uses an alternating electromagnetic signal as its source signal. The alternating current signal excites the transmitting coil (which emits the signal), generating an alternating electromagnetic field in space. The induction coil (which receives the signal) then outputs a signal of the same frequency within the alternating electromagnetic field. Based on the amplitude and phase information of the output signal, the position and orientation of the induction coil relative to the transmitting coil can be calculated, allowing the second positioning device 23 to accurately obtain the position and orientation information transmitted by the first positioning device 12.

[0039] In some embodiments, a hydraulic cylinder (not shown) may be provided on the frame 21 , and the controller 25 may control the hydraulic cylinder to drive the fork wire shaft 22 to move linearly up and down along the frame 21 to achieve coaxiality between the fork wire shaft 22 and the raw wire drum 10 .

[0040] In some embodiments, the crosswire shaft 22 is generally hollow cylindrical, and its diameter is smaller than the inner diameter of the first positioning device 12, thereby allowing the crosswire shaft 22 to directly pass through the first positioning device 12 to complete the extraction of the silk. In some embodiments, the crosswire shaft 22 extends in a first direction A relative to the frame 21, that is, parallel to the length of the raw silk drum 10, so that the crosswire shaft 22 can be coaxially connected to the raw silk drum 10. Then, the crosswire device 20 only needs to move forward to directly fit the raw silk drum 10 onto the crosswire shaft 22.

[0041] In some embodiments, the push rod assembly 24 includes a drive motor (not shown) and a reciprocating, telescopic annular connecting rod 241. The annular connecting rod 241 is sleeved on the cross-wire shaft 22. The controller 25 can control the drive motor to drive the annular connecting rod 241 to reciprocate and slide along the cross-wire shaft, thereby pushing the raw silk reel 10 away from the cross-wire shaft 22. In this embodiment of the present application, the length direction of the cross-wire shaft 22 is parallel to the first direction A, and the height direction of the frame 21 is parallel to the second direction B, that is, the length direction of the cross-wire shaft 22 is perpendicular to the height direction of the frame 21.

[0042] In some embodiments, the cross-thread device 20 may be provided with multiple cross-thread shafts 22, which are arranged in an orderly manner at intervals on the frame 21. In the embodiment of the present application, the cross-thread device 20 can bear a load of up to 150-300 kg, thereby being able to transfer multiple raw yarn drums 10 at the same time.

[0043] In some embodiments, the cross-wire device 20 also includes a start button 26 and an emergency stop button 27 provided on the frame 21. The start button 26 can control the start and end of the movement state of the cross-wire device 20, and the emergency stop button 27 can stop the movement of the cross-wire device 20 in time when encountering an emergency situation.

[0044] It can be understood that the cross-wire device 20 may further include a base (not shown), the frame 21 is provided on the upper surface of the base, and the controller 25 controls the cross-wire device 20 to move in parallel up, down, left, and right.

[0045] See also Figure 4 and Figure 5 The wire withdrawal device 30 includes a wire withdrawal frame 31, a wire withdrawal shaft 32, and a third positioning device 34. One end of the wire withdrawal shaft 32 is connected to the wire withdrawal frame 31. The third positioning device 34 is located inside the wire withdrawal shaft 32 and is used to transmit a position signal. The second positioning device 23 on the wire fork shaft 22 can move the wire fork shaft 22 to coaxially connect with the wire withdrawal shaft 32 based on the position signal emitted by the third positioning device 34. The push rod assembly 24 pushes the original wire drum 10 away from the wire fork shaft 22 and onto the wire withdrawal shaft 32 to complete the wire feeding.

[0046] In some embodiments, the third positioning device 34 is an electromagnetic positioning system transmitter, which can accurately send the position signal of the wire withdrawal shaft 32 through electromagnetic induction, so that the second positioning device 23 can receive the position signal sent by the third positioning device 34 and determine the precise position of the wire withdrawal shaft 32.

[0047] In some embodiments, the wire withdrawal shaft 32 extends along the first direction A relative to the wire withdrawal frame 31, that is, the length direction of the wire withdrawal shaft 32 is parallel to the length direction of the wire fork shaft 22 and the raw wire tube 10, so that the wire fork shaft 22 and the wire withdrawal shaft 32 can be coaxially docked, so that the push rod assembly 24 can smoothly push the raw wire tube 10 to complete the wire loading.

[0048] In the embodiment of the present application, the length direction of the wire withdrawal shaft 32 is parallel to the first direction A, and the height direction of the wire withdrawal rack 31 is parallel to the second direction B, that is, the length direction of the wire withdrawal shaft 32 is perpendicular to the height direction of the wire withdrawal rack 31.

[0049] It can be understood that the diameter of the wire withdrawal shaft 32 is smaller than the inner diameter of the first positioning device 12 , so that the wire withdrawal shaft 32 can pass through the first positioning device 12 to sleeve the raw silk drum 10 on the wire withdrawal shaft 32 .

[0050] In some embodiments, the wire withdrawal device 30 may be provided with multiple wire withdrawal shafts 32, which are spaced and arranged in an orderly manner on the wire withdrawal frame 31. It is understood that the multiple wire withdrawal shafts 32 and the multiple cross-wire shafts 22 are arranged in the same and corresponding manner, so that multiple raw wire drums 10 can be transferred simultaneously to further improve production efficiency.

[0051] In actual production, the method of using the aforementioned automatic wire-threading device may include the following steps:

[0052] (1) See Figure 1 , multiple raw yarn tubes 10 are placed at the transfer location parallel to the ground (ie, the first direction A), and raw yarn 11 is wound on the raw yarn tubes 10.

[0053] (2) Please see Figure 2 and Figure 3 , the cross-wire device 20 is moved to a range no greater than 50 cm from the raw silk drum 10. The first positioning device 12 in the raw silk drum 10 sends a position signal, which is received by the second positioning device 23 in the cross-wire shaft 22. The controller 25 then processes the received position signal, controls the cross-wire device 20 to translate, and moves the cross-wire shaft 22 along the frame 21 to align with the raw silk drum 10. That is, the cross-wire shaft 22 and the raw silk drum 10 are coaxially connected. At this time, the cross-wire device 20 is controlled to continue to move forward, so that the raw silk drum 10 is sleeved on the cross-wire shaft 22, and the silk is taken out.

[0054] (3) Please see Figure 4 and Figure 5The cross-thread device 20 carrying the raw silk drum 10 is moved to a range of no more than 50 cm from the wire withdrawal device 30. The third positioning device 34 in the wire withdrawal device 30 sends a position signal, which is received by the second positioning device 23 in the cross-thread shaft 22. The controller 25 then processes the received position signal, controls the cross-thread device 20 to translate, and causes the cross-thread shaft 22 to coaxially connect with the wire withdrawal shaft 32. At the same time, the push rod assembly 24 is controlled to push the raw silk drum 10 away from the frame 21, so that the raw silk drum 10 is sleeved on the wire withdrawal shaft 32, thus completing the wire feeding.

[0055] The automatic wire-threading equipment provided in the embodiment of the present application can realize the automation of the wire-threading step by setting a first positioning device 12 in the raw wire tube 10, setting a second positioning device 23 in the cross-wire device 20, and setting a third positioning device 34 in the wire-retracting device 30, thereby reducing the risk of damage to the raw wire 11, improving the yield rate, and improving the production efficiency of the carbon fiber production line.

[0056] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
