Description

Technical Field

[0001] This invention relates to the field of carbon fiber production line equipment technology, and in particular to an automatic roll changing device for a carbon fiber production line. Background Technology

[0002] Carbon fiber, as a novel material, possesses excellent mechanical properties such as high strength and high modulus, as well as superior characteristics like high temperature resistance, friction resistance, thermal conductivity, and corrosion resistance. Its low density results in high specific strength and specific modulus. The main application of carbon fiber is as a reinforcing material in composites with resins, metals, ceramics, and carbon, making it an excellent material for manufacturing high-tech equipment in aerospace and other industries. In recent years, with the development of the aerospace industry, domestic demand for carbon fiber has grown rapidly. Domestic carbon fiber manufacturers have made breakthroughs in both large-scale production and technology, achieving continuous production operations.

[0003] Currently, in the winding process of a carbon fiber production line, carbon fiber is wound onto an empty carbon fiber roll by an automated winding machine. Then, workers remove the full roll of carbon fiber from the winding machine, install an empty roll, and continue winding. This process requires manual operation. Due to the continuous nature of carbon fiber production, workers need to be on duty 24 hours a day, resulting in high labor intensity and requiring a high degree of concentration. If the full roll of carbon fiber cannot be removed in time, it will cause the carbon fiber production line to stop, resulting in waste of carbon fiber and affecting the efficiency of the production line. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automatic roll changing device for carbon fiber production lines.

[0005] This invention is achieved through the following technical solution:

[0006] An automated carbon fiber roll changing device for a carbon fiber production line includes a frame, a storage rack, a laser marking machine, a robotic arm motion platform, a robotic arm, full carbon fiber rolls, and empty carbon fiber rolls. The frame controls the movement of the device, including horizontal and turning movements. The storage rack holds the full and empty carbon fiber rolls. The robotic arm, mounted on the robotic arm motion platform, grasps full carbon fiber rolls from the production line, weighs the removed rolls, and feeds the measurement data back to the laser marking machine. The robotic arm then places the full rolls into the storage rack, removes empty carbon fiber rolls from the rack, and places them back into the production line. The robotic arm motion platform enables the robotic arm to move horizontally in three directions and rotate vertically. The laser marking machine marks the removed full carbon fiber rolls with a laser and records the weight and production time information of the removed rolls.

[0007] The frame includes a chassis, a battery power unit, an active differential wheel, driven auxiliary wheels, and a storage rack rotator. The battery power unit is mounted at the bottom of the chassis. There are two active differential wheels located on both sides of the bottom of the chassis. The active differential wheels are driven by a motor. By adjusting the speed difference between the two active differential wheels, the horizontal movement and turning movement of the chassis can be achieved. The driven auxiliary wheels are mounted at both ends of the bottom of the chassis and move in all directions with the active differential wheels. The storage rack rotator is located on both sides of the bottom of the chassis. The storage racks are respectively mounted on the storage rack rotator, and the storage rack rotator drives the storage racks to rotate around an axis.

[0008] The storage rack includes a support base; a support column is fixed on the support base, and multiple support crossbars are fixed on the support column from top to bottom. The support column is located in the middle of the support crossbars. The support base is installed on the storage rack rotator, which drives the support rack base and the support column to rotate around their own axis. The two ends of the support crossbars are used to store full rolls of carbon fiber and empty rolls of carbon fiber, respectively.

[0009] The laser marking machine is installed on the top of the vehicle frame. After the robotic arm takes the full roll of carbon fiber off the carbon fiber production line, it weighs it and feeds back the weight and production time information to the laser marking machine. The laser marking machine then prints the information-bearing mark onto the inner wall of the full roll of carbon fiber.

[0010] The robotic arm motion platform includes a forward and backward motion module, a left and right motion module, a up and down motion module, and a rotational motion module. The forward and backward motion module, the left and right motion module, and the up and down motion module enable the robotic arm to translate in three directions; the rotational motion module enables the robotic arm to rotate around an axis in the vertical direction.

[0011] The front-to-back motion module is installed on the top left and right ends of the frame, the left-to-right motion module is installed between the front-to-back motion module, the two ends of the left-to-right motion module are slidably installed on the front-to-back motion module, and the front-to-back motion module drives the left-to-right motion module to move back and forth. The top end of the up-and-down motion module is slidably installed on the lower side of the left-to-right motion module, and the left-to-right motion module drives the up-and-down motion module to move left and right. The rotary motion module is slidably installed on the front side of the up-and-down motion module, and the up-and-down motion module drives the rotary motion module to move up and down. The robotic arm is installed on the rotary motion module.

[0012] The robotic arm includes a base, grippers, a linkage mechanism, a tension motor, and a load cell. The base is connected to the rotary motion module, the tension motor is mounted on the base, and the load cell is installed between the base and the tension motor. The grippers are connected to the tension motor via the linkage mechanism, which converts the tensioning motion of the tension motor into the opening and closing motion of the grippers. The load cell measures the weight of the full roll of carbon fiber removed by the robotic arm.

[0013] The claw is provided with an outer slot and an inner slot. The outer slot of the claw extends into the inner wall of the full roll of carbon fiber. The claw opens outward to clamp the inner wall of the full roll of carbon fiber and grab the full roll of carbon fiber. After the inner slot of the claw opens, it tightens the outer side of the empty roll of carbon fiber and grabs the empty roll of carbon fiber.

The frame 1 controls the movement of the device, including horizontal and turning movements. The storage rack 2 holds the full roll of carbon fiber 6 and the empty roll of carbon fiber 7. The robotic arm 5 is mounted on the robotic arm motion platform 4. The robotic arm 5 grasps the full roll of carbon fiber 6 from the carbon fiber production line, weighs the removed roll, and feeds the measurement data back to the laser marking machine 3. The robotic arm 5 places the full roll of carbon fiber 6 into the storage rack 2 and removes the empty roll of carbon fiber 7 from the storage rack 2, then places it back into the carbon fiber production line. The robotic arm motion platform 4 enables the robotic arm 5 to move horizontally in three directions and rotate vertically, allowing the robotic arm 5 to move to a designated position. The laser marking machine 3 laser-marks the removed full roll of carbon fiber 6 and records the weight and production time information of the removed roll.

[0029] like Figure 2As shown, the frame 1 includes a frame 11, a battery power unit 12, an active differential wheel 13, a driven auxiliary wheel 14, and a storage rack rotator 15. The frame 11 is the framework of the entire device, used for the installation and fixation of electrical components, etc. The battery power unit 12 is installed at the bottom of the frame 11, providing power to the entire device and driving its operation. There are two active differential wheels 13, located on both sides of the bottom of the frame 11. The active differential wheels 13 are driven by a motor, and the horizontal movement and turning movement of the frame 11 are achieved by adjusting the speed difference between the two active differential wheels 13. The driven auxiliary wheels 14 are installed at both ends of the bottom of the frame 11. The driven auxiliary wheels 14 are used for auxiliary support of the device and can move in all directions with the active differential wheels 13. The storage rack rotator 15 is located on both sides of the bottom of the frame 11, and the storage racks 2 are respectively installed on the storage rack rotator 15. The storage rack rotator 15 drives the storage racks 2 to rotate around an axis. The storage rack rotator 15 is driven to rotate by a motor.

[0030] like Figure 3 As shown, the storage rack 2 includes a support base 21; a support column 22 is fixed on the support base 21, and multiple support crossbars 23 are fixed on the support column 22 from top to bottom. The support column 22 is located in the middle of the support crossbars 23. The support base 21 is installed on the storage rack rotator 15, and the storage rack rotator 15 drives the support base 21 and the support column 22 to rotate around their own axis. The two ends of the support crossbars 23 are used to store full rolls of carbon fiber 6 and empty rolls of carbon fiber 7, respectively.

[0031] The laser marking machine 3 is installed on the top of the frame 1. The robot arm 5 removes the carbon fiber roll 6 from the carbon fiber production line, weighs it, and feeds back the weight and production time information to the laser marking machine 3. The laser marking machine prints the information-attached mark onto the inner wall of the carbon fiber roll 6.

[0032] like Figure 4 As shown, the robotic arm motion platform 4 includes a forward and backward motion module 41, a left and right motion module 42, a up and down motion module 43, and a rotational motion module 44. The forward and backward motion module 41, the left and right motion module 42, and the up and down motion module 43 enable the robotic arm 5 to translate in three directions. Through the coordination of multiple directional movements, the robotic arm 5 can complete the required movements. The rotational motion module 44 enables the robotic arm to rotate around an axis in the vertical direction.

[0033] The front-to-back motion module 41 is installed at the top left and right ends of the frame 11. The left-to-right motion module 42 is installed between the front-to-back motion modules. The two ends of the left-to-right motion module 42 are slidably mounted on the front-to-back motion module 41. The front-to-back motion module 41 drives the left-to-right motion module 42 to move back and forth. The top end of the up-and-down motion module 43 is slidably mounted on the lower side of the left-to-right motion module 42.

The base 51 is connected to the rotary motion module 44. The tension motor 54 is mounted on the base 51, and the weighing sensor 55 is installed between the base 51 and the tension motor 54. The gripper 52 is connected to the tension motor 54 through the linkage mechanism 53, which converts the tensioning motion of the tension motor 54 into the opening and closing motion of the gripper 52. The weighing sensor 55 measures the weight of the full roll of carbon fiber 6 removed by the robotic arm.

[0035] The claw 52 is provided with an outer slot and an inner slot. The outer slot of the claw extends into the inner wall of the full roll of carbon fiber. The claw opens outward to clamp the inner wall of the full roll of carbon fiber and grab the full roll of carbon fiber. After the inner slot of the claw opens, it tightens the outer side of the empty roll of carbon fiber and grabs the empty roll of carbon fiber.

[0036] When the carbon fiber winding machine on the production line is fully wound, the overall control system sends a full-wound signal to the device of this invention. The device moves to the position of the fully wound winding machine via the active differential wheel 13 at the bottom of the frame 1. The robot arm removes the full carbon fiber roll from the winding machine for weighing and feeds back the weight and other information to the laser marking machine 3. The robot arm 5 moves the full carbon fiber roll 6 to the position of the laser marking machine 3, where the laser marking machine 3 marks the inner wall of the full carbon fiber roll. After marking, the robot arm 5 places the full carbon fiber roll on the storage rack 2 for temporary storage. The robot arm 5 then removes the empty carbon fiber roll 7 from the storage rack 2 and installs it onto the winding machine.
