Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of the present invention will be described in further detail below.

[0027] An automated carbon fiber bundle cutting device, such as Figure 1-3 As shown, the present invention includes:

[0028] The feeding mechanism is used to convey and clamp the carbon fiber bundle 4.

[0029] A clamping mechanism is used to clamp and position the carbon fiber bundle 4;

[0030] A cutting mechanism is used to cut the positioned carbon fiber bundle 4;

[0031] Automatic controller 32 is used to control the feeding mechanism, clamping mechanism and cutting mechanism. The feeding mechanism, clamping mechanism and cutting mechanism are all connected to automatic controller 32 through wires. Automatic controller 32 is a Xinje Electric ZG3-30T7 touch screen PLC all-in-one machine. In addition, a control cabinet consisting of buttons, power supply and other components is electrically connected through wires.

[0032] Equipment platform 1 is used to house the feeding mechanism, clamping mechanism, cutting mechanism and automatic controller 32;

[0033] First, the carbon fiber bundle 4 is manually pushed into the feeding mechanism. Then, the automatic controller 32 controls the feeding mechanism to automatically feed the carbon fiber bundle 4. The clamping mechanism and the feeding mechanism convey the carbon fiber bundle 4 and clamp it to a fixed length. Then, the automatic controller 32 controls the cutting mechanism to cut the clamped carbon fiber bundle 4. After completing one cycle, the carbon fiber bundle 4 is fed again to complete the positioning and cutting.

[0034] In this embodiment, as Figure 1-3As shown, the feeding mechanism includes a guide frame 2 mounted on the equipment platform 1, a guide sleeve 3 mounted on the guide frame 2, the guide sleeve 3 being a circular sleeve, the carbon fiber bundle 4 placed in the guide sleeve 3, and copper sleeves 5 evenly arranged on the carbon fiber bundle 4, the copper sleeves 5 being equidistantly arranged on the carbon fiber bundle 4, the copper sleeves 5 and the carbon fiber bundle 4 being reliably fixed by a pressing process, the cross-section of the copper sleeves 5 being larger than the cross-section of the carbon fiber bundle 4, a transfer tensioning slide 6 mounted on the equipment platform 1, a placement platform 7 mounted on the transfer tensioning slide 6, and a tensioning rail 8 fixedly mounted on the placement platform 7. A tensioning seat 10 is slidably mounted on track 8. A support plate 11 is mounted on the tensioning seat 10. A transfer and pressing cylinder 12 is fixedly mounted on the support plate 11. A pressing block 13 is fixedly mounted on the output end of the transfer and pressing cylinder 12. A lower support block 14 that cooperates with the pressing block 13 is fixed on the tensioning seat 10. A V-groove is provided on the lower support block 14 to place the carbon fiber bundle 4 and provide guidance for the carbon fiber bundle 4. A pressing groove is provided at the lower end of the pressing block 13 to fit the copper sleeve 5. The pressing block 13 can fix the copper sleeve 5 more tightly through the pressing groove and the V-groove of the lower support block 14. The carbon fiber bundle 4 is placed between the pressing block 13 and the lower support block 14. Between the support blocks 14, a detection component is installed on the placement platform 7. The transfer and tensioning slide 6 can control the placement platform 7 to move left and right. When the transfer and pressing cylinder 12 drives the pressing block 13 to press the carbon fiber bundle 4 with copper sleeve 5, the pressing block 13 and the lower support block 14 clamp the copper sleeve 5, and then the clamping mechanism is locked between the two copper sleeves 5 on the carbon fiber bundle 4 at the corresponding position, without contacting the carbon fiber bundle 4. At this time, the transfer and tensioning slide 6 moves the placement platform 7 towards the tail end of the carbon fiber bundle 4. Since the pressing block 13 presses the carbon fiber bundle 4, when the placement platform 7 moves towards the tail end of the carbon fiber bundle 4... At this time, the tensioning seat 10, under the frictional force of the tensioning rail 8 and the placement platform 7, moves towards the tail end of the carbon fiber bundle 4 along with the placement platform 7, and drives the carbon fiber bundle 4 to move towards the tail end of the carbon fiber bundle 4. When the copper sleeve 5 on the carbon fiber bundle 4 abuts against the clamping mechanism, the carbon fiber bundle 4 stops moving. At this time, the pressing block 13 and the transfer pressing cylinder 12 remain stationary with the placement platform 7, while the tensioning seat 10 remains stationary. At this time, the placement platform 7 continues to move towards the tail end of the carbon fiber bundle 4, and the tensioning status is detected by the detection component. The transfer tensioning slide 6 and the transfer pressing cylinder 12 are both connected to the automatic controller 32 through wires.

[0035] In this embodiment, as Figure 1-3As shown, the detection assembly includes screws 15 respectively mounted on the placement platform 7 and the tensioning seat 10. A tension spring 16 is installed between the two screws 15. A tension detection sensor 17 is installed on the placement platform 7. The tension detection sensor 17 is a proximity sensor of model E2E-X2D1-NZ. The tension detection sensor 17 is electrically connected to the automatic controller 32 via a wire. Normally, the detection end of the tension detection sensor 17 is in contact with the tensioning seat 10. When the detection end of the tension detection sensor 17 is removed from the tensioning seat 10 and no longer in contact with the tensioning seat 10, feedback information is provided. When the carbon fiber... After the copper sleeve 5 on the carbon fiber bundle 4 presses against the clamping mechanism, the placement platform 7 moves towards the tail end of the carbon fiber bundle 4 to tighten the tension spring 16. The tension spring 16 tightens the tension seat 10, thereby tightening the carbon fiber bundle 4. When the placement platform 7 moves a certain distance towards the tail end of the carbon fiber bundle 4 and the carbon fiber bundle 4 presses against the clamping mechanism and cannot be pulled, the placement platform 7 continues to move towards the tail end of the carbon fiber bundle 4. At this time, the tension detection sensor 17 does not contact the tension seat 10. At this time, the tension detection sensor 17 will send feedback information to the automatic controller 32, which means that the carbon fiber bundle 4 has been tightened. At this time, the transfer tension slide 6 stops driving the placement platform 7 to move.

[0036] In this embodiment, as Figure 1-2 As shown, the cutting mechanism includes a cutting slide 18 mounted on the equipment platform 1, and an electric cutting shear 19 mounted on the cutting slide 18. The electric cutting shear 19 is a C-90 type circular blade cutting machine from Bestwin Technology Co., Ltd., which can quickly cut fibrous materials. Both the cutting slide 18 and the electric cutting shear 19 are connected to the automatic controller 32 via wires.

[0037] In this embodiment, as Figure 1-3As shown, the clamping mechanism includes a V-shaped worktable 20 mounted on the equipment platform 1. A support frame 21 is fixed on the V-shaped worktable 20, and a pressing cylinder 22 is fixed on the support frame 21. A baffle 23 is fixed to the output end of the pressing cylinder 22. A positioning component is installed on the V-shaped worktable 20. A cutting groove 24 is provided on the V-shaped worktable 20 to cooperate with the electric cutting shears 19. When the electric cutting shears 19 cuts the carbon fiber bundle 4, it enters the cutting groove 24. A V-shaped groove 25 is provided on the V-shaped worktable 20 to place the carbon fiber bundle 4. When the second copper sleeve 5 on the uncut carbon fiber bundle 4 passes the baffle 23, the pressing cylinder 22 controls the baffle 23 to move downward, so that the lowest side of the baffle 23 is lower than the upper surface of the copper sleeve 5 and higher than the upper surface of the carbon fiber bundle 4, and does not contact the carbon fiber bundle 4. At this time, the transfer and pressing cylinder 12 drives the movement of the baffle. The transfer clamping block 13 clamps the carbon fiber bundle 4, and then the transfer tensioning slide 6 drives the placement table 7 to move towards the tail end of the carbon fiber bundle 4. The transfer clamping cylinder 12 and the lower support block 14 drive the carbon fiber bundle 4 to move towards the tail end of the carbon fiber bundle 4. The unprocessed carbon fiber bundle 4 moves towards the tail end of the carbon fiber bundle 4. The second copper sleeve 5 on the carbon fiber bundle 4 contacts the baffle 23 and is blocked by the baffle 23, preventing the carbon fiber bundle 4 from moving towards the tail end of the carbon fiber bundle 4. At this time, the transfer tensioning slide 6 continues to drive the placement table 7 to move towards the tail end of the carbon fiber bundle 4. The tensioning seat 10 remains stationary, but the placement table 7 continues to move towards the tail end of the carbon fiber bundle 4. The tensioning seat 10 is tightened by the tensioning spring 16, so that the carbon fiber bundle 4 is also tightened. When the detection end of the tension detection sensor 17 is disengaged from the tensioning seat 10, information feedback is provided. At this time, the carbon fiber bundle 4 is clamped and positioned by the positioning component.

[0038] In this embodiment, as Figure 1-3As shown, the positioning assembly includes a positioning block 26 fixed on a V-shaped worktable 20. Two lifting cylinders 27 are fixedly installed on the V-shaped worktable 20. Lifting blocks 28 are fixed to the output ends of both lifting cylinders 27. A clamping rod 29 is rotatably mounted on each of the two lifting blocks 28. Both clamping rods 29 are rotatably mounted on the positioning block 26 via a clamping shaft 30. When the tension detection sensor 17 detects that the tension has reached a specified value, it reacts, causing the two lifting cylinders 27 to move and drive the lifting blocks 28 to rise. The rising lifting blocks 28 push the clamping rods 29. The clamping rods 29 are adjusted by the clamping shaft 30, with one end rising and the other falling. One end of the carbon fiber bundle 4 is pressed down. At this time, the two pressing rods 29 press the first copper sleeve 5 and the second copper sleeve 5 on the unprocessed carbon fiber bundle 4 respectively. Then, the electric cutting scissors 19 are moved by the cutting slide 18. The electric cutting scissors 19 cuts the positioned carbon fiber bundle 4. The cutting position is between the first copper sleeve 5 and the second copper sleeve 5. Each time the carbon fiber bundle 4 is moved and pressed by the pressing cylinder 12, the tension detection sensor 17 is activated. The length of the unprocessed carbon fiber bundle 4 reserved at the other end of the baffle 23 is equidistant, so that the cut carbon fiber bundle 4 is equidistant. The lifting cylinder 27 and the pressing cylinder 22 are both connected to the automatic controller 32 through wires.

[0039] In this embodiment, as Figure 2-3 As shown, a receiving box 31 is installed on the equipment platform 1. The receiving box 31 is located directly below the tail end of the V-groove 25 on the V-shaped worktable 20. The processed carbon fiber bundle 4 is pushed by subsequent carbon fiber bundles 4 one after another until it falls into the receiving box 31.

[0040] In this embodiment, as Figure 1-2 As shown, the cutting slide 18 and the transfer tensioning slide 6 are AC servo driven automated linear modules.

[0041] The working process of this invention is as follows: First, the carbon fiber bundle 4 to be processed is placed in the guide cylinder, so that the carbon fiber bundle 4 passes through the V-groove and V-shaped groove 25 in sequence, and the first copper sleeve 5 on the carbon fiber bundle 4 passes through the baffle 23. At this time, the automatic controller 32 is activated to automatic mode, and the transfer and pressing cylinder 12 is controlled to drive the transfer and pressing block 13 to press the carbon fiber bundle 4 to be cut. The transfer and tensioning slide 6 automatically moves the second copper sleeve 5 of the carbon fiber bundle 4 to be cut slightly past the baffle 23. The pressing cylinder 22 drives the baffle 23 to press down on the left end of the second copper sleeve 5 of the carbon fiber bundle 4 to block the copper sleeve 5. The transfer and tensioning slide 6 moves towards the tail end of the carbon fiber bundle 4, so that the carbon fiber bundle 4 to be cut moves to the second copper sleeve 5 close to the baffle 23. The transfer and tensioning slide 6 continues to move to the left until the tensioning spring 16 is pulled. The system opens, and simultaneously the tension detection sensor 17 sends a signal. Then, the conveying tension slide 6 stops moving. At the same time, the two lifting cylinders 27 push the lifting block 28 to drive the clamping rod 29 to clamp the first copper sleeve 5 and the second copper sleeve 5 of the carbon fiber bundle 4 to be cut through the clamping shaft 30. The conveying clamping cylinder 12 releases the carbon fiber bundle 4. The conveying tension slide 6 drives the placement table 7 to return to the original position. The electric cutting scissors 19 starts the cutting slide 18 to move quickly forward to approach the carbon fiber bundle 4. The cutting slide 18 drives the electric cutting scissors 19 to move forward at a low speed to cut the carbon fiber bundle 4. After cutting the carbon fiber bundle 4, the cutting slide 18 drives the electric cutting scissors 19 to move quickly back to the original position. The two lifting cylinders 27 reset, and one cycle ends. When the feeding mechanism continues to convey the carbon fiber bundle 4, the processed carbon fiber bundle 4 moves towards the receiving box 31 and falls into the receiving box 31 in sequence.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
