Description

[0002] Carbon fiber board is formed by hardening carbon fibers arranged in the same direction with resin. It can effectively solve the problems of difficult construction and large engineering workload of multi-layer carbon fiber cloth. It has good reinforcement effect and convenient construction. Carbon fiber board has good properties such as high tensile strength, corrosion resistance, seismic resistance, and impact resistance.

In addition, delamination, resin melting, and deflection still exist in the processing through this method. The use of sawing technology to cut carbon fiber composite materials can not only avoid delamination, burrs, and fiber detachment, but also achieve higher processing accuracy through servo control. However, traditional sawing machine cutting has great limitations and cannot adapt to the processing of complex structure workpieces.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the embodiments.

[0035] like Figure 1-Figure 5 The device for cutting carbon fiber sheets using a diamond wire acute-angle cutting method is shown. The cutting device includes a turntable 101, an upper roller 102, a lower roller 103, a diamond wire 104, a left guide rail 105, and a right guide rail 106. The left guide rail 105 and the right guide rail 106 each include a support platform, a conveyor belt, a motor 4, and two rotating rollers. The two rotating rollers are rotatably mounted on the support platform, and the output end of the motor 4 extends through the side wall of the support platform and is welded to one end of one of the rotating rollers. The conveyor belt is mounted on the two rotating rollers. The upper roller 102 and the lower roller 103 are both rotatably mounted on the same surface of the turntable 101 and are centrally symmetrically distributed. The upper roller 102 and the lower roller 103 are both fixedly mounted on the turntable 101 via a plug-in assembly 2, which is provided with a mounting plate 3. Two motors 4, one for each of the upper and lower rollers 102 and 103, are mounted on the side of the turntable 101 away from the upper roller 102 via bolts or a fixed bracket. The output ends of the motors 4 extend through the turntable 101 and are welded or fixedly connected to the mounting plate 3. The two motors 4 can drive the upper and lower rollers 102 and 103 to rotate, respectively, with the upper roller 102 rotating in the opposite direction of the lower roller 103. A diamond wire 104 is wound clockwise around the upper roller 102 at one end and counterclockwise around the lower roller 103 at the other end. The ends of the diamond wire 104 are not welded or otherwise fixedly connected to the upper and lower rollers 102 and 103, respectively. The left guide rail 105 and the right guide rail 106 are arranged side by side with a cutting gap formed therebetween. The lower roller 103 is located inside the cutting gap. The diamond wire 104 is located between the left guide rail 105 and the right guide rail 106. A carbon fiber plate is placed on the top of the right guide rail 106. The carbon fiber plate is transported from the right guide rail 106 to the left guide rail 105 through the right guide rail 106. A high-torque servo 5 for driving the turntable 101 to rotate is installed on the side of the turntable 101 away from the upper roller 102 through bolts.

[0036] The plug-in assembly 2 includes two symmetrically arranged clamping plates 201 and two limiting posts 202, each welded to the adjacent side walls of the two clamping plates 201. The outer circumferential walls of the upper and lower rollers 102 and 103 each have limiting slots 6 for the limiting posts 202 to engage. The two clamping plates 201 are slidably mounted on the side of the mounting plate 3 away from the turntable 101 via an adjustment assembly 7, allowing the two clamping plates 201 to slide closer or further away from each other. The adjustment assembly 7 includes a bidirectional threaded rod 701 and two threaded blocks 702. The mounting plate 3 has a mounting slot 8. The bidirectional threaded rod 701 is rotatably mounted within the mounting slot 8 by a motor 9. The output end of the motor 9 extends through the mounting plate 3 and is welded to one end of the bidirectional threaded rod 701. Motor 2 9 is mounted on one side of the mounting plate 3 by bolts. The spiral lines at both ends of the bidirectional threaded rod 701 are in opposite directions. Two threaded blocks 1 702 are respectively connected to the two ends of the bidirectional threaded rod 701 through spiral transmission. Threaded blocks 1 702 are each provided with a threaded groove 1 for cooperating with the end of the bidirectional threaded rod 701. One side of the splint 201 is welded to the threaded block 1 702.

[0037] The cutting device also includes a mounting frame 107 and a movable frame 108. The movable frame 108 has an L-shaped cross-section and is located directly above the mounting frame 107. The mounting frame 107 is located between the left guide rail 105 and the right guide rail 106. The high-torque servo 5 is bolted to the vertical portion of the movable frame 108 and is arranged away from the turntable 101. A connecting rod 10 is welded to the side of the turntable 101 away from the top roller 102. The output end of the high-torque servo 5 passes through the vertical portion of the movable frame 108 and is welded to one end of the connecting rod 10. The horizontal portion of the movable frame 108 is mounted on the top of the mounting frame 107 by sliding the sliding assembly 11 in the horizontal direction. The sliding assembly 11 includes a screw rod 111 and a second thread block 112. The second thread block 112 is welded to the bottom of the movable frame 108, and the second thread block 112 is spirally connected to the screw rod 111. The second thread block 112 is provided with a second thread groove for cooperating with the screw rod 111. Two mounting bars 12 are welded to the top of the mounting frame 107. The screw rod 111 is rotated and installed between the two mounting bars 12 by the third motor 13. The output end of the third motor 13 passes through one of the mounting bars 12 and is welded to one end of the screw rod 111. The third motor 13 is installed on one of the mounting bars 12 by bolts. The first motor 4, the second motor 9, the third motor 13 and the fourth motor are all servo motors.

[0038] When the upper roller 102 and the lower roller 103 need to be replaced, the motor 2 is started to drive the bidirectional threaded rod 701 to rotate. The bidirectional threaded rod 701 cooperates with the thread groove 1 on the thread block 1 702, so that the bidirectional threaded rod 701 rotates clockwise and drives the two thread blocks 1 702 away from each other. When the thread block 1 702 moves, the clamping plate 201 and the limiting column 202 respectively move until the clamping plate 201 is no longer in contact with the upper roller 102 or the lower roller 103, and the limiting column 202 is disengaged from the limiting groove 6 on the upper roller 102 or the lower roller 103, so that the upper roller 102 and the lower roller 103 can be removed from the two mounting plates 3 for replacement. In addition, the limiting groove 6 is provided on the upper roller 102 and the lower roller 103 of different diameters, so that the plug-in assembly 2 can install upper rollers 102 and lower rollers 103 of different diameters.

[0039] By starting motor three 13 to drive the screw rod 111 to rotate, and the screw rod 111 cooperates with the thread groove two on the thread block two 112 through the screw rod 111, so that when the motor three 13 drives the screw rod 111 to rotate clockwise, it can respectively drive the thread block two 112, the movable frame 108, the turntable 101, the upper roller 102, the lower roller 103 and the diamond wire 104 to move toward the middle position close to the right guide rail 106, and the moving direction of the movable frame 108 is relatively perpendicular to the transmission direction of the right guide rail 106. When the motor three 13 drives the screw rod 111 to rotate counterclockwise, it can respectively drive the thread block two 112, the movable frame 108, the turntable 101, the upper roller 102, the lower roller 103 and the diamond wire 104 to move toward the edge position close to the right guide rail 106, so as to adjust the contact position of the diamond wire 104 and the carbon fiber plate, so that the carbon fiber plate can be cut into two parts of the same width or different widths by the diamond wire 104.

[0040] A control method for a carbon fiber plate cutting device based on a diamond wire sharp angle cutting method, using the carbon fiber plate cutting device, comprises the following steps:

Two motors 104 are started to drive the upper roller 102 and the lower roller 103 to rotate simultaneously and continuously. The upper roller 102 and the lower roller 103 rotate in opposite directions to achieve reciprocating linear motion of the diamond wire 104.

[0042] S2. The right guide rail 106 drives the carbon fiber sheet to be cut to the left. The uncut portion of the carbon fiber sheet is cut by the diamond wire 104 and moves to the left a certain distance (this distance can be set according to actual conditions). Then, it retreats to the right and starts the servo 5 to drive the turntable 101 to rotate counterclockwise by 2 (90°-θ);

[0043] S3. The right guide rail 106 drives the carbon fiber sheet to be cut to the left. The uncut portion of the carbon fiber sheet is cut by the diamond wire 104 and moves to the left a certain distance (this distance can be set according to actual conditions and is generally the same as or similar to the distance traveled in step S2). Then, the diamond wire 104 moves back to the right and the servo 5 drives the turntable 101. The diamond wire 104 returns to a position where the angle θ between the diamond wire 104 and the carbon fiber sheet to be cut is set.
