[0002] Resin-based composite materials are advanced materials composed of synthetic resin as the matrix and high-performance fibers, particles, etc. as reinforcing materials. They are thermosetting resins such as epoxy resins, unsaturated polyester resins, etc., or thermoplastic resins such as polyetheretherketone, polyphenylene sulfide, etc. The resin matrix plays the role of bonding reinforcing materials, transferring loads, and protecting reinforcing materials from environmental influences in composite materials. It gives the composite material a certain degree of formability, allowing the material to be processed into products of different shapes and sizes through various processes.

[0003] During the processing of resin-based composite materials, the resin-based composite materials need to be cut and sampled. At present, the cutting machines used on the market will generate a large amount of debris when cutting resin-based composite materials.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3The utility model provides an embodiment: a resin-based composite material sample preparation device, including a workbench 1 and a cutting assembly. The workbench 1 serves as the basic platform of the entire device and provides a support surface for the installation and operation of all other components. The cutting assembly is installed on the top of the workbench 1. The outer side of the cutting assembly is fixedly connected to an air cylinder 4, which is the core component for generating airflow. The air is inhaled and discharged through the movement of the internal piston 6. A sliding rod 5 is slidably connected to the through hole on the side wall of the air cylinder 4. One end of the sliding rod 5 is fixedly connected to a piston 6, which slides in the air cylinder 4 and changes the air flow of the air cylinder 4 through its reciprocating motion. The air pressure inside realizes the suction and discharge of air. The other end of the sliding rod 5 is fixedly connected to a spring 7. An air inlet 8 is provided on the outside of the air cylinder 4. One end of the air cylinder 4 is fixedly connected to an exhaust pipe 9. A one-way valve is provided inside the air inlet 8 and the exhaust pipe 9. One end of the exhaust pipe 9 is fixedly connected to a nozzle 10. A unloading assembly is provided on the top of the workbench 1. The unloading assembly is used to move the cut resin material out of the top of the workbench 1. The outer side of the piston 6 is slidably connected to the inner side of the air cylinder 4. One end of the spring 7 is fixedly connected to the outer side of the air cylinder 4. The cutting assembly includes a linear module 2. One end of the linear module 2 is fixedly connected to the top of the workbench 1. A mounting bracket 3 is fixedly connected to the moving seat of the linear module 2. On the one hand, it is used to fix the air cylinder 4 and the cutting machine 11 and other components so that they maintain a stable relative position during work; on the other hand, it serves as a bridge connecting the linear module 2 and other components to transmit the power of the linear module 2 to the cutting machine 11 etc., to achieve overall collaborative work. The inner side of the mounting frame 3 is fixedly connected to the outer side of the cylinder 4. A cutting machine 11 is installed on the outer side of the mounting frame 3. One end of the rotating shaft of the cutting machine 11 is fixedly connected to a cam 12. Its contour shape enables it to periodically push the sliding rod 5 during rotation, thereby driving the piston 6 to reciprocate in the cylinder 4. The outer side of the cam 12 fits with one end of the sliding rod 5.

[0024] Specifically, when performing the sample preparation operation of the resin-based composite material, the operator places the resin material on the top of the workbench 1, and the clamping mechanism 14 on the workbench 1 begins to work. These clamping mechanisms 14 have adjustable clamps, which are driven by cylinders and can be flexibly adjusted according to the shape and size of the resin material. They will tightly clamp the edge of the resin material to ensure that the resin material can maintain a stable position during the subsequent cutting process. The cutting machine 11 and the linear module 2 are started. The linear module 2 is a high-precision linear motion control device. The linear module 2 will drive the cutting machine 11 to move down according to the preset program, gradually approaching the resin material, and preparing to cut it. At the same time, the cutting machine 11 is started, and its internal cutting blade rotates at high speed. Let the cam 12 rotate with the rotating shaft. During the rotation process, its protruding part will periodically contact one end of the sliding rod 5 and push the sliding rod 5 to move into the inside of the air cylinder 4. When the cam 12 pushes the sliding rod 5, the sliding rod 5 will drive the piston 6 to slide in the air cylinder 4 and squeeze the spring 7 at the same time. The spring 7 will store elastic potential energy when squeezed. As the cam 12 continues to rotate, when the protruding part of the cam 12 separates from the sliding rod 5, the elastic force stored in the spring 7 will be released, causing the sliding rod 5 to reset. In this way, under the continuous rotation of the cam 12, the piston 6 will move back and forth. When the piston 6 slides outward, negative pressure will be formed inside the air cylinder 4. At this time, outside air will enter the air cylinder 4 through the air inlet 8. The one-way valve arranged inside the air inlet 8 allows air to flow into the air cylinder 4 in one direction only, preventing the air in the air cylinder 4 from flowing back out. When the piston 6 slides inward, the air in the air cylinder 4 will be squeezed out and ejected from the nozzle 10 through the exhaust pipe 9. While cutting, the surface of the workbench 1 can be blown clean, and the debris generated during the cutting process can be cleaned in time to prevent the debris from interfering with the cutting process.

[0025] Reference Figure 2-Figure 4, three clamping mechanisms 14 are installed on the top of the workbench 1, and a strip-shaped hole 13 is opened in the middle of the top of the workbench 1 to reserve space for the cutting operation. The unloading assembly includes a motor 15, which is installed on the top of the workbench 1. The output end of the motor 15 is fixedly connected to a winding rod 16, which is used to retract and release the pull rope 17. By rewinding or releasing the pull rope 17, the length and tension of the pull rope 17 are changed. The outer side of the rewinding rod 16 is fixedly connected to the pull rope 17, which is used to transmit the power of the motor 15 and convert the rotational motion of the rewinding rod 16 into the linear motion of the sliding rod 19. The pull rope One end of 17 is fixedly connected to a sliding rod 2 19, and one end of the sliding rod 2 19 is fixedly connected to an impact block 20, which is used to directly impact the cut resin material, and the resin material is separated from the top of the workbench 1 by the impact force to complete the unloading action. The top of the workbench 1 is fixedly connected to a fixed plate 18, and the outer side of the sliding rod 2 19 is slidably connected to the internal sliding hole of the fixed plate 18. The outer side of the sliding rod 2 19 is provided with a spring 21, and one end of the spring 21 is fixedly connected to the outer side of the impact block 20, and the other end of the spring 21 is fixedly connected to the outer side of the fixed plate 18.

[0026] Specifically, before cutting the resin material, start the motor 15. After the motor 15 starts running, its output end will drive the winding rod 16 to rotate. During the rotation of the winding rod 16, the pull rope 17 will be wrapped around its outside. As the pull rope 17 is continuously wrapped around the winding rod 16, the pull rope 17 will generate tension and drive the sliding rod 2 19 and the impact block 20 to move together. At the same time, the spring 21 will be squeezed and contracted to store elastic potential energy. When the resin material is cut, turn off the brake of the motor 15. At this time, under the elastic force of the spring 21, the sliding rod 2 19 and the impact block 20 are quickly pushed to their original positions. During the rapid movement, the impact block 20 can quickly push the cut resin material away from the top of the workbench 1. This automatic unloading method eliminates the need for manual picking operations, which not only improves work efficiency but also avoids the risk of injury due to manual operation.

[0027] Working principle: First, place the resin material on the top of the workbench 1, the clamping mechanism 14 will clamp the edge of the resin material, and then start the cutting machine 11 and the linear module 2, so that the cutting machine 11 moves down to cut the resin material. At the same time, the start of the cutting machine 11 will drive the cam 12 to rotate, and push the sliding rod 5 to drive the piston 6 to slide, and squeeze the spring 7. The elastic force of the spring 7 can reset the sliding rod 5, so that the piston 6 will move back and forth, realizing the suction from the air inlet 8 and spraying out from the nozzle 10 through the exhaust pipe 9, which can blow and clean the surface of the workbench 1 while cutting.

[0028] In addition, before cutting the resin material, the motor 15 is started to drive the winding rod 16 to rotate, and the pull rope 17 is wrapped around the outside of the winding rod 16, while driving the sliding rod 19 and the impact block 20 to move. At this time, the spring 21 is squeezed and contracted. When the resin material is cut, the brake of the motor 15 is turned off. Under the elastic force of the spring 21, the impact block 20 moves quickly to push the cut resin material away from the top of the workbench 1, eliminating the need for manual picking up operations.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
