Description

Technical Field

[0001] This utility model relates to the field of carbon fiber felt processing technology, and more specifically, to an automatic carbon fiber felt cutting device. Background Technology

[0002] Carbon fiber felt possesses broad-spectrum adsorption properties and is used as a porous electrode and catalyst support in fuel cells. Depending on the specific application, carbon fiber felt requires a series of processing methods, including cutting, impregnation, pressing, and high-temperature treatment.

[0003] Before the actual cutting process, the thickness of existing carbon fiber felt needs to be measured. Most current thickness measurement methods use vernier calipers, but due to the special nature of carbon fiber felt, vernier calipers can easily damage its surface during measurement. Furthermore, manual thickness measurement can only be done by sampling, not by measuring the entire roll of carbon fiber felt, making it impossible to guarantee that the entire roll meets the requirements. Overall, the measurement method has significant limitations. At the same time, carbon fiber felt needs to be cut to specified dimensions to facilitate subsequent processing. Manual cutting is prone to large dimensional errors, has poor flatness, and the use of cutting tools can be dangerous, especially when the force is high. To address these problems, a solution is proposed below. Utility Model Content

[0023] Example 1:

[0024] Please see Figure 1-5 An automatic carbon fiber felt cutting device includes a base 1, a controller 27 mounted on the base 1, and a feeding component 2 on the base 1. The feeding component 2 includes a bracket 19 and a support rod 20. Two brackets 19 are provided and symmetrically installed on the upper end face of the base 1. A notch 21 is opened on the upper end face of the bracket 19. The support rod 20 is rotatably arranged inside the notch 21. Limiting plates are installed at both ends of the support rod 20 to prevent the support rod 20 from moving in the notch 21 and to ensure stability.

[0025] A sliding groove 22 is symmetrically provided on the base 1. A lead screw 23 is rotatably installed inside the sliding groove 22. A drive motor 25 is connected to one side of the base 1. The drive motor 25 is electrically connected to the controller 27. One end of the drive motor 25 is fixedly connected to the lead screw 23. A slider 24 is slidably installed inside the sliding groove 22. The lead screw 23 passes through the slider 24 and is threadedly engaged. A moving stage 6 is provided on one side of the loading component 2. The slider 24 and the moving stage 6 are fixedly connected. Several rolling rods 26 are installed on the top of the moving stage 6. The rolling rods and the moving stage 6 rotate in coordination. A thickness measuring light curtain 3 is installed on the moving stage 6. A width measuring light curtain 4 is provided on one side of the thickness measuring light curtain 3. Both the thickness measuring light curtain 3 and the width measuring light curtain 4 are electrically connected to the controller 27. Both the thickness measuring light curtain 3 and the width measuring light curtain 4 are ordinary measuring light curtains. The measuring light curtain includes a transmitting end and a receiving end. The transmitting end and the receiving end are arranged in parallel and symmetrically. The thickness measuring light curtain 3 and the width measuring light curtain 4 are perpendicular to each other, thus forming a rectangular measuring channel 5.

[0026] A cutting component 7 is slidably mounted on the base 1. The cutting component 7 is fixedly connected to the moving table 6. The cutting component 7 includes a cutting frame 12, an electric slide rail 13, a cylinder 14, a cutting blade 15, and a distance sensor 16. The cutting frame 12 is fixedly connected to the moving table 6. The electric slide rail 13 is mounted on the cutting frame 12. The cylinder 14 is arranged vertically and mounted on the output end of the electric slide rail 13. The cutting blade 15 is fixedly connected to the output end of the cylinder 14. The distance sensor 16 is mounted on the side of the cylinder 14, and the output direction of the distance sensor 16 is the same as the moving direction of the output end of the electric slide rail 13. The electric slide rail 13, the cylinder 14, and the distance sensor 16 are all electrically connected to the controller 27.

[0027] A guide rod 8 is symmetrically connected to one side of the cutting piece 7. One end of the guide rod 8 is connected to a pulley 9, and the other end of the guide rod 8 is equipped with an encoder 10. The encoder 10 is connected to the pulley 9 and electrically connected to the controller 27. The encoder 10 identifies the position of the pulley 9 at this time. A clamping assembly 11 is installed on the base 1. The clamping assembly 11 includes a clamping block 17 and a connecting frame 18. The connecting frame 18 is installed on the upper surface of the base 1. The clamping block 17 and the connecting frame 18 are rotatably engaged, and the clamping block 17 is in contact with the upper surface of the base 1.

[0028] Working principle:

[0029] Before use, the carbon fiber felt is placed on the support rod 20, and the support rod 20 is placed on the recess 21. The support rod 20 can rotate inside the recess 21. First, the motor is started, and the motor drives the moving table 6 to move. The moving table 6 drives the cutting piece 7 and the guide rod 8 to move. The guide rod 8 drives the pulley 9 to roll. When the pulley 9 contacts the clamping block 17, the pulley 9 will lift the clamping block 17. The user passes the carbon fiber felt through the upper end face of the rolling rod 26, the detection channel and the bottom of the cutting piece 7 in sequence, and lays it flat on the upper end face of the base 1. At the same time, one end of the carbon fiber felt will be placed on the bottom of the clamping block 17.

[0030] The measuring light curtain is a special type of photoelectric sensor. Like ordinary through-beam photoelectric sensors, it consists of two separate, oppositely placed transmitters and receivers. However, it is larger in size, resembling a long tube. The detection light emitted by the measuring light curtain transmitter is not a single beam like in ordinary sensors, but rather an array of beams spaced at regular intervals along its length, forming a "light curtain." This light curtain, in conjunction with the controller 27 and its software, scans and monitors the dimensions of objects. The thickness of the carbon fiber felt is detected through the thickness measuring light curtain 3, and the width of the carbon fiber felt is detected through the width measuring light curtain 4, thus achieving real-time detection of the carbon fiber felt's dimensions. This eliminates the need for manual inspection, making it accurate and efficient.

[0031] The drive motor 25 drives the lead screw 23 to rotate, which in turn drives the slider 24 to move. The slider 24 then drives the moving table 6 to move, which in turn drives the cutting piece 7 to move. The cutting piece 7 then drives the guide rod 8 to move, which in turn drives the pulley 9 to move. As a result, the pulley 9 removes its support from the clamping block 17, and the clamping block 17 falls onto the carbon fiber felt under the influence of gravity, clamping one end of the carbon fiber felt. The rolling of the pulley 9 drives the input end of the encoder 10 to rotate. The encoder 10 is connected to the controller 27, which can calculate the moving distance of the pulley 9 and thus determine the moving distance of the cutting piece 7. When the moving distance of the cutting piece 7 is the same as the preset length of the carbon fiber felt to be cut, the moving table 6 stops moving.

[0032] Cylinder 14 pushes the cutting blade 15 to move, so that the cutting blade 15 comes into contact with the base 1. The electric slide rail 13 is activated, and the electric slide rail 13 will drive the cylinder 14 to move. The cylinder 14 drives the cutting blade 15 to move, and the carbon fiber felt is cut by the cutting blade 15. At the same time, when the cylinder 14 moves, the cylinder 14 will drive the distance sensor 16 to move. The distance sensor 16 can know the position of the cutting blade 15 in real time, which is convenient for interaction with the controller 27.
