Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber strip cutting, in particular to an automatic carbon fiber strip cutting device. Background Art

[0002] As a high-performance material in modern industry, precise cutting of carbon fiber tape is crucial to ensure product quality. Currently, laser cutting machines are mostly used for cutting to carry out the processing and production of carbon fiber tape.

[0003] In the process of using the existing laser cutting machine to laser cut the carbon fiber strip, it starts with the automatic conveyor strip accurate positioning, and then scans the material surface along a preset path by focusing the high-energy laser beam to achieve fast and contactless cutting. However, during the laser cutting process, the existing laser cutting machine will cause the local temperature of the carbon fiber strip to rise sharply due to the difference in heat input and material thermal conductivity, causing the resin matrix to melt or even vaporize, thereby producing harmful gas phase components. At the same time, the carbon fiber may also break or ablate due to high temperature. Secondly, because the carbon fiber has high hardness and high brittleness, it is easy to break when subjected to thermal stress or mechanical stress. During the melting process, the carbon fiber may break into small pieces or debris due to factors such as temperature gradient, thermal stress concentration or mechanical shock. These carbon fiber strip debris will be mixed in the end of the cut strip. In the subsequent processing process, these carbon fiber debris may produce tiny dust particles due to processing. If these particles are inhaled or come into contact with the skin of the staff, it will cause harm to their health.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0038] like Figures 1 to 10As shown, an automatic cutting device for carbon fiber strips described in an embodiment of the present invention comprises a workbench, wherein two support plates are fixedly connected to the upper surface of the workbench, and a first guide rail is provided on the upper surfaces of the two support plates, and the same first guide plate is slidably connected in the two first guide rails, and a fixed plate is slidably connected to the lower surface of the first guide plate, and a slide groove is provided on one side of the fixed plate, and a slider is slidably connected in the slide groove, and a laser cutting head is fixedly connected to one side of the slider; a conveyor belt is rotatably connected between the two support plates; a second guide rail is provided in the middle part of each support plate, and the same second guide plate is slidably connected to the two second guide rails, and a cooling assembly is arranged on the upper surface of the second guide plate, and the cooling assembly comprises a storage box fixedly connected to the upper surface of the second guide plate, a cross plate is fixedly connected to one side of the storage box, and a plurality of nozzles are fixedly connected to the lower surface of the cross plate, and the nozzles are used to spray water mist.

[0039] Specifically, when using an existing laser cutting machine to laser cut carbon fiber tapes, it starts with the automatic conveyor tape being accurately positioned, and then a focused high-energy laser beam is scanned along a preset path on the material surface to achieve fast, contactless cutting. However, during the laser cutting process, the existing laser cutting machine, due to the difference in heat input and material thermal conductivity, will cause the local temperature of the carbon fiber tape to rise sharply, causing the resin matrix to melt or even vaporize, thereby generating harmful gas phase components;

[0040] Therefore, the present invention solves this problem by setting a certain structure. First, the conveyor belt drives the carbon fiber strip to move to the bottom of the laser cutting head. When the size of the carbon fiber strip is measured, the fixed plate sliding on the lower surface of the first guide plate is started to drive the laser cutting head to one side of the carbon fiber strip. Then, the laser cutting head is moved downward along the slide groove through the slider to make the laser cutting head close to the carbon fiber strip. Then, the laser cutting head is started to cut. During cutting, the fixed plate drives the laser cutting head to move toward the other side of the carbon fiber strip, thereby realizing the cutting of the carbon fiber strip. While the carbon fiber strip is being cut, the second guide plate on the second guide rail is started to move to a position close to the laser cutting head. At this time, the laser cutting head triggers several nozzles on the lower surface of the horizontal plate on one side of the fixed box. Wherever the laser cutting head moves, the nozzle at that location will spray water mist, thereby absorbing harmful gas phase components generated during the cutting process of the carbon fiber strip, so that these harmful gas phase components cannot diffuse, thereby achieving the effect of protecting the working environment.

[0041] The problem that the local temperature of the carbon fiber tape rises sharply due to the difference in heat input and material thermal conductivity, causing the resin matrix to melt or even vaporize, thereby generating harmful gas phase components is solved.

[0042] like Figure 5 As shown, a guide groove is provided on one side of the second guide plate in this embodiment, a guide block is slidably connected in the guide groove, and a soft cloth is fixedly connected to the middle of the guide block.

[0043] Specifically, because carbon fiber is hard and brittle, it is easy to break when subjected to thermal stress or mechanical stress. During the melting process, the carbon fiber may break into small pieces or debris due to factors such as temperature gradient, thermal stress concentration or mechanical impact. These carbon fiber strip debris will be mixed in the end of the cut strip. In the subsequent processing, these carbon fiber debris may generate tiny dust particles due to processing. If these particles are inhaled or come into contact with the skin of workers, they will cause harm to their health;

[0044] Therefore, after cutting a section of carbon fiber strip, the guide block slidingly connected in the guide groove on one side of the second guide plate is immediately started. The guide block will drive the soft cloth fixed in the middle to wipe the cut and broken part of the carbon fiber strip wetted by the spray. Because the soft cloth becomes adsorbent after absorbing water, it can adsorb carbon fiber debris. Therefore, the carbon fiber debris on both sides of the cut and broken part of the carbon fiber strip can be cleaned, thereby achieving the effect of improving the cutting quality and protecting the health of subsequent processing workers.

[0045] like Figure 6 and Figure 7 As shown, in this embodiment, a plurality of first cavities are provided inside the transverse plate, and a fixing hole is provided on the bottom surface of each first cavity. A plurality of second cavities are also provided inside the transverse plate, and a connecting hole is provided on the bottom surface of each second cavity, and the connecting hole is fixedly connected to the nozzle. A convex rod is slidably connected in each second cavity, and a compression spring is fixedly connected to one side of the convex rod, and the end of the compression spring away from the convex rod is fixedly connected to the transverse plate, and a positioning hole is provided on the surface of the convex rod. A paddle plate is fixedly connected to one side of the fixing plate, and the paddle plate is used to squeeze and push the convex rod.

[0046] Specifically, when the fixed plate drives the laser cutting head to move, it will drive the paddle plate fixed on one side thereof to abut against the horizontal plate to move. In the process of abutting against the horizontal plate, the paddle plate will squeeze the protruding rods one by one as the laser cutting head moves. In the process of the paddle plate squeezing the protruding rods, the protruding rods will squeeze the compression springs inwards and then retract into the second cavity. After retracting into the second cavity, the fixing hole of the first cavity and the connecting hole of the second cavity are connected through the positioning hole of the protruding rod, and then the water in the storage box will flow into the nozzle and then be sprayed out from the nozzle, as shown in the attached figure. Figure 6 and Figure 7 As shown, the effect of saving water resources is achieved, and at the same time, the uncut carbon fiber strip in front is not affected, and the effect of timely cooling is achieved, thereby improving the cutting quality of the carbon fiber strip.

[0047] like Figure 5 As shown, a pressure pump is fixedly connected to the upper surface of the storage box in this embodiment, and a sealing cover is threadedly connected to the upper surface of the storage box, and the sealing cover is used for filling water.

[0048] Specifically, by starting the pressure pump on the upper surface of the storage box, the pressure pump will pressurize the water in the storage box, and then pressurize the water inside the storage box into the first cavity. When the convex rod is squeezed, the water in the first cavity can be squeezed out of the nozzle. Then, when the water in the storage box is used to a certain extent, the sealing cover is turned by threading. By opening the sealing cover, water can be added to the storage box, so that the laser cutting machine can continue to work and improve production efficiency.

[0049] like Figure 8 As shown, a connecting frame is fixedly connected to one side of the workbench of this embodiment, and the connecting frame is located directly below the soft cloth. Two moving rods are slidably connected inside the connecting frame. A scraper block is slidably connected to the top of each moving rod. The scraper block can slide along the side groove of the moving rod, and the cross-section of each scraper block is conical.

[0050] Specifically, when the soft cloth wipes the cut part of the carbon fiber strip, water and carbon fiber debris will be absorbed on the soft cloth. If the water in the soft cloth continues to be absorbed and reaches saturation, the wiping effect of the soft cloth will be reduced next time. Therefore, the guide block drives the soft cloth to move to the top of the connecting frame, and then the two moving rods in the connecting frame are started, so that the two moving rods clamp the soft cloth in the middle, and then the scraping block at the top of each moving rod is started to slide along the side groove of the moving rod. The side groove is an electric guide rail, so the two scraping blocks can scrape off the water and carbon fiber debris on the soft cloth, thereby improving the cleaning efficiency of the soft cloth, and then improving the cleaning effect of the carbon fiber debris.

[0051] like Figure 8 As shown, in this embodiment, a fixing frame is arranged below the connecting frame, and the fixing frame is fixedly connected to one side of the workbench.

[0052] Specifically, a fixed frame is provided below the connecting frame, and then the fixed frame is used to collect water and carbon fiber debris scraped from the soft cloth by the scraping block, thereby achieving a unified collection effect and being able to recycle the carbon fiber debris.

[0053] like Figure 8 As shown, in this embodiment, a filter screen is fixedly connected in the fixed frame, and a plurality of through holes are opened on the surface of the filter screen. The filter screen is used to separate carbon fiber debris and water.

[0054] Specifically, by fixing the filter screen in the fixed frame, the carbon fiber debris and water can be separated, the recycling effect of the carbon fiber debris is improved, the collection process is simplified, and there is no need for subsequent separate separation. Embodiment 2

[0055] like Figures 1 to 10As shown, compared with Example 1, another implementation of the present invention is: an auxiliary plate is fixedly connected to one side of the workbench, a motor is fixedly connected to the upper surface of the auxiliary plate, a transmission roller is fixedly connected to the output end of the motor, the transmission roller is used to drive the conveyor belt, two limit blocks are fixedly connected to one side of the workbench, the two limit blocks are rotatably connected to the same reciprocating screw, the output end of the motor is also fixedly connected to a gear, the gear transmission is connected to a strip steel, one end of the reciprocating screw is also fixedly connected to a gear, the strip steel can be transmission-connected to drive the reciprocating screw, the circumferential surface of the reciprocating screw is slidably connected to a moving block, the side of the moving block close to the conveyor belt is fixedly connected to a cleaning brush, and the cleaning brush is used to clean the carbon fiber material remaining on the conveyor belt.

[0056] Specifically, after cutting, some carbon fiber debris may remain and be adsorbed on the conveyor belt. Therefore, after the motor starts to drive the conveyor belt, it will also drive the gear at its output end to rotate. After the gear rotates, it can drive the strip steel to rotate, and then the strip steel can drive the reciprocating screw to rotate. The rotation of the reciprocating screw can drive the moving block on its circumferential surface to slide, and the sliding moving block will drive the cleaning brush on one side to clean the surface of the conveyor belt, thereby achieving the effect of improving the transmission quality of the conveyor belt and preventing the carbon fiber debris on the conveyor belt from adhering to the carbon fiber strip.

[0057] like Fig.10 As shown, in this embodiment, the upper surface of the moving block is fixedly connected with a top block, the upper surfaces of the two limiting blocks are fixedly connected with the same limiting plate, and the lower surface of the limiting plate is provided with a limiting groove, and the moving block can be limited by sliding along the limiting groove through the top block.

[0058] Specifically, during the movement of the moving block, a top block is fixedly connected to the upper surface of the moving block, and then the top block slides along the limiting groove, thereby achieving the effect that the moving block can more stably drive the cleaning brush to clean.

[0059] like Fig.10 As shown, a guide plate is fixedly connected to one side of the workbench in this embodiment, and the guide plate abuts against the conveyor belt. A collection frame is clamped on one side of the workbench, and the collection frame is used to collect carbon fiber debris.

[0060] Specifically, the carbon fiber debris cleaned by the cleaning brush will fall into the collection frame along the guide plate, and then the collected carbon fiber debris can be recycled.

[0061] Working principle: first, the conveyor belt drives the carbon fiber strip to move directly under the laser cutting head. When the size of the carbon fiber strip is measured, the fixed plate sliding on the lower surface of the first guide plate is started to drive the laser cutting head to one side of the carbon fiber strip. Then, the laser cutting head is moved downward along the slide groove through the slider to make the laser cutting head close to the carbon fiber strip. Then, the laser cutting head is started for cutting. During cutting, the fixed plate will drive the laser cutting head to move to the other side of the carbon fiber strip, thereby realizing the cutting of the carbon fiber strip. While the carbon fiber strip is being cut, the second guide plate on the second guide rail is started to move to a position close to the laser cutting head. At this time, the laser cutting head will drive the paddle fixed on one side to move against the cross plate. When it abuts against the cross plate, the laser cutting head will move to the other side of the cross plate. In the process of connecting the horizontal plate, the paddle plate will squeeze the convex rods one by one as the laser cutting head moves. In the process of the paddle plate squeezing the convex rods, the convex rods will squeeze the compression spring inwards and then retract into the second cavity. After retracting into the second cavity, the fixing hole of the first cavity and the connecting hole of the second cavity are connected through the positioning hole of the convex rod, and then by starting the pressure pump on the upper surface of the storage box, the pressure pump will pressurize the water in the storage box and pressurize the water inside it into the first cavity. When the convex rods are squeezed, the water in the first cavity can be squeezed out of the nozzle. Then, when the water in the storage box is used to a certain extent, the sealing cover is turned by threading. Opening the sealing cover can fill the storage box with water, so that the laser cutting machine can continue to work and improve production efficiency, and then it is sprayed out from the nozzle, as shown in the attached figure. Figure 6 and Figure 7 As shown, the effect of saving water resources is achieved, and at the same time, the uncut carbon fiber strip in front is not affected, and the effect of timely cooling is achieved, thereby improving the cutting quality of the carbon fiber strip;

[0062] Wherever the laser cutting head moves, the nozzle at that location will spray water mist, thereby absorbing the harmful gas phase components generated during the cutting process of the carbon fiber strip, making these harmful gas phase components unable to diffuse, thus achieving the effect of protecting the working environment;

[0063] After a section of carbon fiber strip is cut, the guide block slidably connected in the guide groove on one side of the second guide plate is immediately started. The guide block drives the soft cloth fixed in the middle thereof to wipe the cut and broken part of the carbon fiber strip wetted by the spray. Because the soft cloth becomes absorbent after absorbing water, it can absorb the carbon fiber debris, so the carbon fiber debris on both sides of the cut and broken part of the carbon fiber strip can be cleaned, thereby achieving the effect of improving the cutting quality and protecting the health of the subsequent processing workers.

[0064] When the soft cloth wipes the cut part of the carbon fiber strip, water and carbon fiber debris will be absorbed on the soft cloth. If the water in the soft cloth is saturated, the wiping effect of the soft cloth will be reduced. Therefore, the guide block drives the soft cloth to move to the top of the connecting frame, and then the two moving rods in the connecting frame are started, so that the two moving rods clamp the soft cloth in the middle, and then the scraping block at the top of each moving rod is started to slide along the side groove of the moving rod. The side groove is an electric guide rail, so the two scraping blocks can scrape the water and carbon fiber debris on the soft cloth, which improves the cleaning efficiency of the soft cloth, and then improves the cleaning effect of the carbon fiber debris.

[0065] After cutting, some carbon fiber debris may remain adsorbed on the conveyor belt. Therefore, after the motor starts to drive the conveyor belt, it will also drive the gear at its output end to rotate. After the gear rotates, it can drive the steel strip to rotate, and then the steel strip can drive the reciprocating screw to rotate. The rotation of the reciprocating screw can drive the moving block on its circumferential surface to slide. The sliding moving block will drive the cleaning brush on one side to clean the surface of the conveyor belt, thereby improving the transmission quality of the conveyor belt and preventing the carbon fiber debris on the conveyor belt from adhering to the carbon fiber strip.

[0066] Finally, the cutting of the carbon fiber strip is completed.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
