Description

Technical Field

[0001] The invention relates to the field of laser cutting, in particular to a belt conveying light slit following laser cutting blanking device. Background Art

[0002] Belt conveyor light slit following laser cutting blanking equipment is usually an automated device that is used to automatically control the belt conveyor system during the laser cutting sheet metal coiling process to ensure that the cut parts are smoothly moved from the laser cutting area to the blanking area, thereby realizing a continuous production process. This type of equipment can improve production efficiency and accuracy in laser cutting processing and reduce manual intervention. It is particularly suitable for situations that require a large number of continuous cutting.

[0003] The belt conveyor light slit following laser cutting blanking equipment on the market is usually set to only fix sheet metal coils of a specific size, which results in the belt conveyor light slit following laser cutting blanking equipment being able to only process sheet metal coils of a specific inner diameter, limiting the flexibility and scope of application of the equipment, resulting in the inability to meet the processing requirements of special inner diameters or shapes. Secondly, laser cutting is a high-precision processing method that requires the workpiece to remain stable during the processing process. If the sheet metal coil cannot be stably fixed, it will cause the workpiece to move or shake during the cutting process, thereby affecting the cutting accuracy and quality. At the same time, the instability of the sheet metal coil during the cutting process will Leading to accidents, for example, the overall position of the sheet metal coil is offset during the feeding process, which in turn causes the sheet metal coil to fall and cause personal injury or equipment damage. At the same time, the inability to fix the sheet metal coil will increase the adjustment and setting time and reduce production efficiency. In addition, since the stability of the workpiece cannot be guaranteed, more inspections and corrections are required, further reducing production efficiency. In addition, if the workpiece moves or shakes during the cutting process, the cutting position will deviate from the expected position, resulting in material waste. Finally, for customers who require customized processing, the inability to fix sheet metal coils with different inner diameters cannot meet their flexibility and personalized needs.

[0004] The belt conveyor light slit following laser cutting blanking equipment on the market cannot grind and clean the sheet metal coils synchronously after cutting, which means that after cutting is completed, the conveyor belt must be stopped and the processing area must be cleared before grinding and cleaning operations can be performed. Because the cutting and cleaning of this process are carried out separately, a lot of time will be wasted, which reduces production efficiency. Secondly, the separation of the cutting and cleaning processes leads to the interruption of the production line, and the downtime will be extended, thereby affecting the continuity and efficiency of the entire production process and increasing production costs. At the same time, separate cutting and cleaning require more human resources to operate, such as requiring additional workers to carry out cleaning work, which will increase labor costs and lead to waste of human resources. Because the cutting equipment is idle during the cleaning process, the equipment utilization rate is low, which in turn affects the overall efficiency of the production line. Finally, the cutting slag and waste generated during the cutting process will remain in the processing area, increasing the risk of workers being injured during the cleaning process. In addition, the cleaning agent used in the cleaning process will also cause damage to the workers, increasing safety hazards. If the sheet metal parts are not cleaned in time after cutting, the quality of the product will be affected, such as scratches or stains, thereby reducing the market competitiveness of the product.

[0005] At the same time, after the belt-conveyed light-slit-following laser cutting blanking equipment on the market cuts the sheet metal coil, there will still be sheet metal left on the sheet metal coil. During the cutting process, if the laser parameters (such as power, speed, frequency, etc.) are not set properly, it will lead to incomplete cutting, and some sheet metal will remain on the coil. If the laser power is too low or the speed is too fast, the sheet metal cannot be completely cut through, resulting in sheet metal residue. If the cutting speed is too slow, it may cause overheating and deformation, thus affecting the cutting effect. Secondly, if there are quality problems with the sheet metal material itself, such as uneven surface, oxides or other impurities, etc., it will affect the effect of laser cutting and lead to incomplete cutting.

[0006] Finally, traditional laser cutting machines usually use screw fixing. During the process of the laser cutter grinding metal materials, the laser cutter will generate vibration due to the continuous grinding of the metal materials, and the screw fixation will gradually deform or slightly displace the screw connection under long-term vibration. As a result, the position offset of the laser cutter will make the cutting line inaccurate, affecting product quality, and inaccurate cutting can easily cause the workpiece to be scrapped, increasing production costs. In addition, the position of the laser cutter needs to be frequently calibrated and adjusted, wasting time and manpower, affecting the overall production progress.

[0007] Therefore, it is necessary to provide a belt conveying light slit following laser cutting blanking equipment to solve the above problems. Summary of the invention

[0018] Preferably, the annular push plate is rotatably connected to the inside of the sliding ring, and the annular push plate and the sliding ring are both slidably connected to the outer wall of the limiting sliding rod.

[0019] Compared with the prior art, the belt conveying light slit following laser cutting blanking equipment provided by the present invention has the following beneficial effects:

[0020] 1. Through the setting of the size adjustment component, the metal push rod group will stop magnetically attracting after the electromagnet block group loses magnetic attraction, and the reset spring will elastically contract to drive the metal push rod group and the annular push plate to contact the sliding ring, and the sliding ring will drive one end of the second rotating rod group to move toward the rotating ring. When the sliding ring conflicts with the rotating ring, the angle between the first rotating rod group and the second rotating rod group continues to decrease, which causes the first rotating rod group and the second rotating rod group to synchronously push the contact plate group to move away from the limit sliding rod. During the movement of the contact plate group, it will gradually contact the inner wall of the sheet metal coil, thereby achieving the purpose of fixing the sheet metal coil;

[0021] Secondly, after the electromagnetic block group loses its magnetic attraction, the magnetic attraction of the metal push rod group stops, thereby triggering the fixing of the sheet metal coil. Compared with the traditional method of fixing by mechanical energy, the spring fixation uses elastic potential energy and does not require additional electrical energy or mechanical energy. In comparison, the use of electrical energy or mechanical energy to fix the material requires additional energy supply, while the spring fixation saves energy consumption. At the same time, the spring fixation does not require an external power supply or mechanical device, and only elastic force is required to achieve fixation. Therefore, it has the characteristics of simplicity and reliability, is not easily disturbed and damaged by external factors, and avoids problems caused by circuit failure or mechanical failure. The spring can be designed and selected according to the required fixing force, and has a certain degree of adaptability. The spring stiffness and length and other parameters can be adjusted to achieve appropriate fixation under different fixing requirements. Since the spring fixation does not involve complex electrical or mechanical components, the maintenance cost is relatively low. The spring itself has a long service life and is not easily damaged, thereby reducing the frequency and cost of maintenance and replacement.

[0022] Secondly, it keeps the sheet metal coil stable during the feeding process, reduces the impact of workpiece movement or shaking on cutting accuracy, thereby improving cutting accuracy and quality. At the same time, compared with the traditional method of manually setting fixing devices for coils of different inner diameters, the reset spring pushes the annular push plate to resist the movement of the sliding ring, thereby achieving the purpose of quickly fixing the sheet metal coil by the resistance plate group, and achieving the purpose of installing the workpiece on the equipment more quickly, reducing unnecessary waiting time, and at the same time reducing safety hazards caused by accidental movement or shaking, and reducing the possibility of accidents. Secondly, sheet metal coils of different inner diameters can be quickly fixed, thereby improving the scope of application and flexibility of the equipment.

[0023] 2. Through the setting of the contact plate group, when the contact plate group contacts the sheet metal coil, the laser cutting machine housing drives one end of the sheet metal coil to move, so that the sheet metal coil drives the first rotating rod group and the second rotating rod group to rotate through the contact plate group, and the first rotating rod group and the second rotating rod group drive the rotating ring and the sliding ring around the limit slide rod to rotate away from the contact plate group, so as to achieve the purpose of magnetic feeding of the sheet metal coil;

[0024] Among them, because the side of the resistance plate group away from the first rotating rod group and the second rotating rod group is set to an arc surface, the arc surface support can provide a more uniform supporting force, reducing the uneven stress distribution on the sheet metal coil, avoiding excessive pressure on the sheet metal during the fixing process, thereby reducing the risk of deformation and damage. At the same time, the resistance of the arc surface support against the inner wall of the sheet metal coil effectively prevents the sheet metal from sliding or shifting during transportation or use, ensuring that it is firmly fixed in the required position. At the same time, the contact between the arc surface support and the inner wall of the sheet metal coil reduces the friction and scratches directly contacting the surface of the sheet metal coil. Finally, the arc surface support can provide a more stable supporting surface, reducing the movement or shaking of the sheet metal coil caused by external shock or vibration, and maintaining the stability of the sheet metal coil.

[0025] 3. Through the setting of the driving component, when the electromagnet block group is energized, the electromagnet block group can quickly magnetically attract the metal push rod group, so that the metal push rod group pulls the annular push plate and the sliding ring to reset, so that the sliding ring drives one end of the second rotating rod group to rotate. At the same time, because the distance between the two bidirectional rotating rod groups and the first rotating rod group and one end of the contact plate group is continuously expanding, the contact plate group moves toward the direction of the limit sliding rod, so that the purpose of indirectly releasing the fixed sheet metal coil is achieved by only energizing the electromagnet block group. Compared with the traditional sheet metal coil fixing method, the operation is simpler and faster, which reduces the operation time of workers in debugging the fixed sheet metal coil equipment and improves the operation efficiency.

[0026] Secondly, compared with traditional clamps or fixtures, magnets have stronger adsorption force and can trigger the required operation quickly and reliably. Once the external magnetic field meets the triggering conditions, the operation will be executed immediately, thereby achieving an efficient triggering process and improving the flexibility of the equipment. Magnets usually have high stability and reliability and are not affected by environmental conditions such as temperature, humidity, etc., which ensures the accuracy and repeatability of the operation.

[0027] 4. Through the setting of the cleaning component, when the driving device drives the rotating rod to rotate, the rotating rod will drive the threaded sliding column to move back and forth horizontally through the connecting rod. During the movement of the threaded sliding column, the threaded sliding column will drive the threaded groove cylinder to rotate back and forth inside the columnar groove block. At the same time, the threaded groove cylinder will drive the gear ring to mesh with the tooth bar, so that the tooth bar drives the T-shaped slide plate to move back and forth horizontally during the process of meshing with the gear ring. During the movement of the T-shaped slide plate, the cleaning wire group at the bottom will be driven to perform horizontal reciprocating cleaning on the sheet metal parts after laser cutting, and the horizontal reciprocating movement can make the cleaning tool better contact To the surface of the object, especially for the relatively flat sheet metal raw materials of new energy vehicles targeted by laser cutting machines, so that the cleaning effect of the sheet metal after laser cutting is better. Secondly, compared with one-way cleaning, horizontal reciprocating movement can save time and energy, shorten the cleaning cycle, and at the same time, horizontal reciprocating movement can make the sliding speed of the cleaning tool on the surface more stable, reducing the change of surface friction caused by the change of direction, thereby reducing the risk of damaging the surface, ensuring that the surface of the sheet metal after cutting is smooth and scratch-free, and removing pollutants and residues generated during the cutting process, improving the production quality of the product, and reducing the risk of workers being injured during operation;

[0028] Furthermore, compared with the traditional process of cutting and cleaning being carried out separately, grinding and cleaning begins immediately during the cutting process, saving equipment downtime and not requiring additional processes, thereby improving equipment production efficiency and reducing production cycles. Secondly, simultaneous cutting and grinding and cleaning means that the cutting equipment and grinding equipment can operate at the same time, thereby improving equipment utilization.

[0029] 5. Through the setting of the cleaning component, the T-shaped slide plate is driven to move horizontally and reciprocatingly during the meshing process between the tooth bar and the gear ring. During the movement of the T-shaped slide plate, the cleaning wire group at the bottom is driven to resist the sheet metal parts after laser cutting, and then the cleaning wire group is caused to resist the sheet metal parts remaining on the coil, so that the sheet metal raw materials and the sheet metal parts are separated, avoiding the part of the sheet metal remaining on the coil due to inappropriate laser parameter setting of the equipment, achieving the purpose of assisting the removal of the remaining sheet metal, ensuring that the quality of the produced sheet metal products is more stable and reliable, effectively reducing the sheet metal parts remaining on the coil, thereby reducing the scrap rate of sheet metal parts, saving raw materials and reducing production costs;

[0030] At the same time, it improves the unloading efficiency of the belt conveyor light slit following laser cutting blanking equipment, solves the problem of incomplete unloading of traditional equipment, makes the operation of the production line more continuous and efficient, improves the overall efficiency of the production line, and reduces the subsequent secondary processing steps caused by incomplete unloading.

[0031] 6. Through the setting of the anti-loosening component, when the first mortise and tenon positioning ring and the second mortise and tenon positioning ring are used to fix the fixing screw and the laser cutter, because the first mortise and tenon positioning ring and the second mortise and tenon positioning ring have special shapes of threads and wedge structures, when the screws are tightened, the interaction between the threads of the first mortise and tenon positioning ring and the second mortise and tenon positioning ring will generate an axial tightening force, and at the same time, the wedge structures of the first mortise and tenon positioning ring and the second mortise and tenon positioning ring will form a tight fit and extrusion with the connecting parts.

[0032] Moreover, due to the existence of the wedge-shaped structure, even if it is subjected to a certain degree of vibration or stress changes during long-term use, it can still maintain a good tightening state. Its principle also includes that after the screw is tightened, through special design, its internal stress distribution and mechanical balance state are conducive to maintaining the tightening effect and reducing the possibility of loosening, thereby maintaining the high-precision cutting effect of the laser cutter, making the lines cut by the laser cutter more precise and smooth, improving product quality, avoiding cutting defects caused by changes in the position of the laser cutter, reducing the scrap rate, and reducing the steps of stopping to adjust the position of the laser cutter. At the same time, it improves production efficiency, reduces production interruptions and rework caused by equipment failure or precision problems, and reduces the frequency and cost of equipment maintenance caused by loose screws.

[0033] 7. Through the setting of the feeding auxiliary component, the L-shaped lever rod can be driven to rotate through the power transmission belt during the operation of the belt conveyor, and the L-shaped lever rod can drive the connecting rod to move, so that the distance between the first sliding plate and the second sliding plate is continuously reduced or increased, so that the first sliding plate and the second sliding plate can be driven to flatten the sheet metal coil during the movement, thereby ensuring that the sheet metal coil remains flat during cutting, avoiding cutting errors caused by unevenness, making the laser cutting path more accurate, and preventing problems such as uneven cutting surface and edge burrs on the surface of the sheet metal coil.

The end of the assist spring group 74 away from the positioning plate 71 is fixedly connected to the first sliding plate 72 and the second sliding plate 73. The first sliding plate 72 is internally rotatably connected to an L-shaped lever rod 75. The outer wall of the L-shaped lever rod 75 is rotatably connected to a connecting rod 76, and the end of the connecting rod 76 away from the L-shaped lever rod 75 is rotatably connected to the second sliding plate 73. A first resistance plate 77 is fixedly connected above the second sliding plate 73. A second resistance plate 78 is fixedly connected to the top of the first sliding plate 72. A power transmission belt 79 is transmission-connected between the end of the L-shaped lever rod 75 away from the connecting rod 76 and the belt conveyor 12.

[0069] After the sheet metal coil is mounted on the belt conveyor light slit following laser cutting blanking equipment, the staff energizes the driving device 43, and then the driving device 43 is energized to drive the rotating rod 44 to rotate. During the rotation of the rotating rod 44, one end of the connecting rod 45 is driven to move, and the other end of the connecting rod 45 drives the threaded slide post 46 to move toward the threaded groove cylinder 48. During the sliding process of the threaded slide post 46 along the inside of the threaded groove cylinder 48, the threaded slide post 46 drives the threaded groove cylinder 48 to rotate along the inside of the columnar groove block 47, and at the same time, the threaded groove cylinder 48 During the rotation, the gear ring 49 will be driven to mesh with the toothed bar 54, and then the gear ring 49 will push the toothed bar 54 to move toward the direction of the belt conveyor 12, so as to achieve the purpose of making the T-shaped slide plate 53 slide back and forth horizontally along the inside of the T-shaped slide groove 52. After the belt conveyor light gap follows the laser cutting blanking equipment to cut the sheet metal coil, the belt conveyor 12 will drive the cut sheet metal to move. When the cut sheet metal passes the bottom of the T-shaped slide plate 53, the T-shaped slide plate 53 will reciprocate and polish the cut sheet metal through the cleaning wire group 55 at the bottom.

[0070] While the cleaning wire group 55 is reciprocatingly grinding and cleaning the cut sheet metal material, if the inside of the sheet metal material cannot be completely cut through due to the low laser power or too fast speed of the equipment, resulting in sheet metal residue, the cleaning wire group 55 will prevent the cut sheet metal from falling off during the grinding of the sheet metal material, thereby achieving the purpose of assisting the removal of the cut sheet metal piece.

[0071] Working principle: In the initial state, the return spring 34 is stretched, the metal push rod group 33 and the hollow cylinder group 32, the electromagnet block group 31 and the metal push rod group 33 are in conflict, and the sliding ring 29 does not conflict with the rotating ring 25.

[0072] During operation, when the belt conveyor light gap follows the laser cutting blanking equipment to cut the sheet metal coil, the sheet metal coil needs to be fixed first.

[0073] The staff first sleeves the sheet metal coil on the outside of the abutment plate group 27, and then the staff cuts off the power to the electromagnet block group 31. At this time, the electromagnet block group 31 loses its magnetism due to power failure, and then the electromagnet block group 31 stops magnetically attracting the metal push rod group 33. At this time, the return spring 34 elastically contracts and drives the metal push rod group 33 to move away from the electromagnet block group 31. During the sliding process of the metal push rod group 33 along the inner part of the hollow cylinder group 32, the annular push plate 35 will be pushed to move toward the rotating ring 25, and at the same time, the annular push plate 35 will synchronously push the sliding ring 29 to move toward the rotating ring 25.

[0074] When the sliding ring 29 moves toward the rotating ring 25, the sliding ring 29 drives one end of the first rotating rod set 26 to move toward the rotating ring 25, and the end of the first rotating rod set 26 away from the sliding ring 29 rotates along the inside of the abutment plate set 27. At the same time, as the sliding ring 29 moves toward the rotating ring 25, the second rotating rod set 28 gradually becomes perpendicular to the sliding ring 29 and the abutment plate set 27, so that the abutment plate set 27 moves away from the limiting sliding rod 23. During the movement of the abutment plate set 27, one end of the first rotating rod set 26 is driven to rotate inside it, and the other end of the first rotating rod set 26 rotates along the inside of the rotating ring 25.

[0075] When the contact plate group 27 moves away from the outer side of the limit slide bar 23 and gradually contacts the sheet metal coil, the purpose of fixing the sheet metal coil by the contact plate group 27 is achieved, and the side of the contact plate group 27 away from the first rotating rod group 26 and the second rotating rod group 28 is set to an arc surface, so that the contact plate group 27 can firmly contact the sheet metal coil. When the belt conveyor 12 drives the sheet metal coil to feed, the sheet metal coil will drive the contact plate group 27 to rotate around the limit slide bar 23, and the contact plate group 27 drives the sliding ring 29 and the rotating ring 25 to rotate around the limit slide bar 23 through the first rotating rod group 26 and the second rotating rod group 28, thereby achieving the purpose of continuously rotating the sheet metal coil, so that the sheet metal coil can be continuously fed.

[0076] When the staff needs to remove the sheet metal coil or replace it with a new one, in contrast to the above-mentioned movement process, the staff first energizes the electromagnet block group 31, and then energizes the electromagnet block group 31 to magnetically attract the metal push rod group 33, so that the metal push rod group 33 slides along the inside of the hollow tube group 32, and the assembly stretches the reset spring 34. At the same time, the metal push rod group 33 pulls the sliding ring 29 away from the rotating ring 25 through the annular push plate 35. Because the sliding ring 29 drives one end of the second rotating rod group 28 to move away from the rotating ring 25, the contact plate group 27 gradually moves toward the direction close to the limit slide rod 23, thereby achieving the purpose of resetting the contact plate group 27.

[0077] At the same time, when the sheet metal coil enters the interior of the laser cutting machine housing 11 for cutting, the belt conveyor 12 will drive the L-shaped lever 75 to rotate along the interior of the first sliding plate 72 through the power transmission belt 79. During the rotation of the L-shaped lever 75, the end of the L-shaped lever 75 away from the power transmission belt 79 will drive the connecting rod 76 to rotate, and then the connecting rod 76 will be pulled by the L-shaped lever 75 first. At this time, the first sliding plate 72 and the second sliding plate 73 both move in a direction close to each other, and at the same time, the first sliding plate 72 and the second sliding plate 73 will both compress the assist spring group 74;

[0078] The first and second sliding plates 73 are moved in a direction away from each other, and the assist spring group 74 elastically extends to assist the first and second sliding plates 72 and 73 in the moving direction. During the movement of the first and second sliding plates 72 and 73, both of them will drive the first and second contact plates 77 and 78 at the top to move back and forth, thereby causing the first and second contact plates 77 and 78 to contact each other after the sheet metal coil enters the laser cutting machine housing 11, so that the part of the sheet metal coil entering the laser cutting machine housing 11 is flattened after being contacted by the first and second contact plates 77 and 78.

[0079] After the sheet metal coil is mounted on the belt conveyor light slit following laser cutting blanking equipment, the staff energizes the driving device 43, and then the driving device 43 is energized to drive the rotating rod 44 to rotate. During the rotation of the rotating rod 44, one end of the connecting rod 45 is driven to move, and the other end of the connecting rod 45 drives the threaded slide post 46 to move toward the threaded groove cylinder 48. During the sliding of the threaded slide post 46 along the inside of the threaded groove cylinder 48, the threaded slide post 46 drives the threaded groove cylinder 48 to rotate along the inside of the columnar groove block 47. At the same time, during the rotation of the threaded groove cylinder 48, the gear ring 49 is driven to mesh with the tooth bar 54, so that the gear ring 49 drives the tooth bar 54 to move toward the belt conveyor 12.

[0080] After the driving device 43 is powered on, it will continue to drive the rotating rod 44 to rotate. In contrast to the above-mentioned movement process, during the rotation of the rotating rod 44, the threaded slide post 46 will be driven by the connecting rod 45 to move away from the threaded groove cylinder 48. At this time, the threaded slide post 46 will drive the threaded groove cylinder 48 to rotate in the opposite direction along the inside of the columnar groove block 47. At the same time, during the rotation of the threaded groove cylinder 48, the gear ring 49 will be driven to rotate in the opposite direction, so that the gear ring 49 drives the toothed bar 54 to move away from the belt conveyor 12.

[0081] Thus, the purpose of making the T-shaped slide plate 53 slide horizontally back and forth along the inside of the T-shaped slide groove 52 is achieved. After the belt conveying light slit follows the laser cutting blanking equipment to cut the sheet metal coil, the belt conveying device 12 will drive the cut sheet metal to move. When the cut sheet metal passes the bottom of the T-shaped slide plate 53, the T-shaped slide plate 53 will reciprocate and polish the cut sheet metal through the cleaning wire group 55 at the bottom.

[0082] While the cleaning wire group 55 is reciprocatingly grinding and cleaning the cut sheet metal material, if the inside of the sheet metal material cannot be completely cut through due to the low laser power or too fast speed of the equipment, resulting in sheet metal residue, the cleaning wire group 55 will prevent the cut sheet metal from falling off during the grinding of the sheet metal material, thereby achieving the purpose of assisting the removal of the cut sheet metal piece.

[0083] Among them, when the displacement device 13 drives the laser cutter 14 to cut the sheet metal coil, the laser cutter 14 continuously polishes the sheet metal coil and generates vibration. Under long-term vibration, the connection between the fixing screw 61 of the laser cutter 14, the laser cutter 14 and the displacement device 13 gradually deforms or slightly displaces. The setting of the first mortise and tenon positioning ring 64 and the second mortise and tenon positioning ring 63, when connecting the laser cutter 14 and the displacement device 13, as the fixing screw 61 is gradually screwed in, the wedge-shaped parts of the first mortise and tenon positioning ring 64 and the second mortise and tenon positioning ring 63 will wedge into the inside of the fixing screw 61 and the laser cutter 14, generating huge friction and bite force. This friction can effectively resist the dynamic loads such as vibration and impact generated by the laser cutter 14 when cutting the sheet metal coil, prevent the fixing screw 61 from loosening under the action of these external forces, and thereby achieve the purpose of stably fixing the laser cutter 14.
