Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, and specifically relates to a laser cutting conveyor line. Background Technology

[0002] Laser cutting equipment for sheet metal uses a high-energy-density laser beam as the "blade," focusing it on the surface of a metal sheet to instantly melt or vaporize the material, achieving precise cutting. It boasts advantages such as high cutting speed, high precision, and a small heat-affected zone. It can cut various metals including stainless steel and carbon steel, and is widely used in machinery manufacturing, automotive, aerospace, and other fields. Before processing, the sheet metal needs to be transported to the laser cutting equipment using a conveyor system.

[0003] A related technology (Chinese utility model patent with announcement number CN208450844U) discloses a conveyor line for an automated production line of laser-cut metal sheets. The conveyor line includes a frame, a material tray, upper and lower conveyor lines arranged in two layers along the length of the frame, upper and lower drive motors for rotating the upper and lower conveyor lines respectively, and multiple baffle assemblies spaced apart on the upper conveyor line to limit the movement of the material tray. The material trays move horizontally on the upper and lower conveyor lines. The baffle assembly includes a drive cylinder vertically fixed to the frame and a baffle fixedly mounted on the piston rod of the drive cylinder to control the material tray to stop moving forward and vibrate. The conveyor line can smoothly, accurately, and efficiently transport cut small metal sheets, while its structure is simple and easy to install and operate.

[0004] Current conveyor lines used in laser cutting lack positioning and conveying capabilities. During the material transport process, the lack of effective constraints and guiding mechanisms makes it prone to deviations and skewing. These transport deviations result in positional and angular errors when the material enters the laser cutting station, severely affecting the accuracy of the cutting trajectory and processing precision, and hindering the efficient and stable operation of the laser cutting process.

[0019] The advantages of this laser cutting conveyor line compared with the prior art are as follows:

[0020] I. To address the problem that existing laser cutting conveyor lines lack effective constraint and guidance mechanisms, easily leading to deviations and skews, resulting in positional and angular errors when the sheet material enters the laser cutting station, severely affecting the accuracy of the cutting trajectory and processing precision, and hindering the efficient and stable operation of the laser cutting process, this invention constructs a side constraint and guidance system through the coordinated cooperation of a guide component and a positioning cylinder. Combined with the end-limiting structure formed by the blocking component, it implements three-dimensional positioning control for the sheet material conveyed along the conveyor component. During the sheet material transmission process, this conveying and positioning function can correct the trajectory in real time, ensuring that the sheet material maintains a precise linear motion posture, effectively avoiding laser cutting station positioning errors caused by sheet material deviation, significantly improving cutting trajectory accuracy and processing quality, and ensuring efficient, stable, and precise operation of laser cutting.

[0021] II. The waste conveying system structure added in this utility model relies on the coordinated operation of the first conveyor line and the second conveyor line components to build an automated waste collection and conveying system. This system automatically transports the waste generated by laser cutting of sheet metal, realizing centralized processing of waste. Compared with the traditional method of waste falling directly to the ground, this design significantly shortens the equipment cleaning and maintenance cycle, effectively integrates sheet metal conveying, cutting and waste collection, and significantly improves the automation level and production efficiency of the overall processing flow.

[0022] Third, in this utility model, the guide wheel adopts a rotating design, which effectively guides and limits the side of the plate while replacing sliding friction with rolling friction, significantly reducing the frictional resistance when the side of the plate moves along the surface of the guide wheel, thereby reducing wear on the plate surface, improving conveying smoothness and guiding accuracy, and optimizing overall transmission efficiency.

[0023] IV. This utility model adopts an integrated drive mechanism, which realizes the linkage control of all conveying rollers through synchronous transmission. Under the action of this drive system, the conveying rollers operate in coordination with the same direction and speed, forming a continuous and stable conveying power, realizing the automated transmission of the sheet material to the conveying platform conveying components. Thus, by driving multiple conveying rollers to work together through a single power source, the synchronization and reliability of the transmission system are significantly improved, effectively ensuring the smoothness and stability of the sheet material conveying.

[0024] V. This utility model establishes a plate lifting function through the coordinated arrangement of the support component and the lifting cylinder. This allows the plate located on the conveying platform to be smoothly lifted off its surface, so that the plate is in a suspended processing state. This effectively avoids damage to the components of the conveying platform during the cutting operation, and ensures that the conveying component can still maintain normal conveying function after the current batch of plates has been processed, thus ensuring the stability and reliability of continuous operation of the equipment.

[0025] VI. By setting a toothed plate, this utility model can achieve the function of stable lifting and supporting the plate while adopting an optimized contact structure to significantly reduce the contact area between the toothed plate and the lower surface of the plate. This effectively avoids the limitation of the cutting space on the traditional support structure, reserves sufficient operating space for the subsequent laser cutting process, and ensures that the cutting beam can act on the plate without obstruction, thereby improving the feasibility of the cutting process and the processing efficiency.

[0026] VII. The roller in this utility model can achieve precise positioning of the end of the board. In addition, through the rotational connection structure between the roller and the shaft, the height of the roller can be flexibly adjusted, so that the roller can be adaptively adjusted according to the change of board thickness, ensuring that the end positioning of different specifications of boards can be obtained during the processing, effectively improving the equipment's adaptability and positioning accuracy for processing diverse boards.

[0027] In summary, in this invention, the side constraint guiding system, in conjunction with the end limiting structure, enables three-dimensional positioning control of the sheet metal, real-time trajectory correction, avoidance of positioning errors, improvement of cutting accuracy, and ensures efficient and stable operation of laser cutting. The automated waste collection and conveying system automatically transports waste generated from laser cutting of the sheet metal, achieving centralized waste processing, significantly shortening the equipment cleaning and maintenance cycle, effectively integrating sheet metal conveying, cutting, and waste collection, and significantly improving the automation level and production efficiency of the overall processing flow. The rotating guide wheel replaces sliding friction with rolling friction, reducing frictional resistance. Force reduces wear on the sheet metal, improves conveying smoothness and guiding accuracy; the integrated drive mechanism enables linkage control of the conveying rollers, improving transmission synchronization and reliability, and ensuring smooth and stable sheet metal conveying; the sheet metal lifting function, constructed by the support component and the lifting cylinder, allows the sheet metal to be processed in mid-air, avoiding damage to the conveying platform components and ensuring stable continuous operation of the equipment; the toothed plate reduces the contact area, reserves cutting space, and improves the feasibility and efficiency of the cutting process; the rollers can accurately position the end of the sheet metal and can flexibly adjust the height to adapt to sheet metal of different thicknesses, improving the equipment's adaptability and positioning accuracy for processing diverse sheet metals.

Detailed Implementation

[0045] The following are specific implementation cases and appendices. Figures 1 to 16 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0046] A laser cutting conveyor line for conveying sheet metal during cutting includes: a frame 1, a waste conveying system 2, positioning cylinders 4, a conveying assembly 5, a guiding assembly 7, and a blocking assembly 9. The waste conveying system 2 is located inside the frame 1 and is used for conveying sheet metal waste. Multiple positioning cylinders 4 are arranged above the frame 1 in a front-to-back direction for guiding and constraining the sheet metal in the front-to-back direction. The conveying assembly 5 is located at the top of the frame 1 and is used for conveying the sheet metal. Two rows of guiding assemblies 7 are arranged in a front-to-back manner above the frame 1. Multiple blocking assemblies 9 are arranged above the frame 1 and are located to the left of the conveying assembly 5 for constraining and limiting the left end of the sheet metal. The blocking assembly 9, the guiding assembly 7, and the positioning cylinders 4 together form a three-dimensional constraint and guiding limit for the sheet metal.

[0047] This invention innovatively designs a side-constraint guiding system composed of a guide component 7 and a positioning cylinder 4, which is linked with the end-limiting structure formed by the blocking component 9 to construct a three-dimensional positioning system for the sheet metal on the conveying platform conveying component 5. Throughout the sheet metal conveying process, this positioning system can monitor and automatically calibrate the sheet metal's travel path in real time, ensuring high-precision linear trajectory conveying through precise constraint and guidance mechanisms. This design effectively eliminates laser cutting positioning deviations caused by sheet metal offset during traditional conveying processes, significantly improving cutting accuracy and processing quality, and providing a solid guarantee for efficient, stable, and precise laser cutting production.

[0048] Main references Figure 4 As shown, frame 1 includes: uprights 1001, horizontal frames 1002, vertical frames 1003, and mounting brackets 1004. Multiple uprights 1001 are provided, and the multiple uprights 1001 are arranged vertically. Two horizontal frames 1002 are provided, and the two horizontal frames 1002 are symmetrically installed at the top of the uprights 1001. A positioning cylinder 4 is fixedly installed on the horizontal frame 1002. Multiple vertical frames 1003 are provided, and the multiple vertical frames 1003 are installed vertically between the two horizontal frames 1002 in the front-to-back direction. The mounting bracket 1004 is fixedly installed at the top of the rear horizontal frame 1002. The uprights 1001, horizontal frames 1002, and vertical frames 1003 form a frame, providing support and installation positions for the subsequent installation of other components.

[0049] Main references Figure 1 Zhongzhi Figure 4 , Figure 14 and Figure 16 As shown, the waste conveying system 2 includes: a first conveyor line 2001 and a second conveyor line 2002. The first conveyor line 2001 is horizontally positioned within the cavity of the frame 1 and conveys materials from left to right. The second conveyor line 2002 is horizontally positioned within the cavity of the frame 1 and conveys materials from back to front. The first conveyor line 2001 is higher than the second conveyor line 2002, and the right end of the first conveyor line 2001 extends above the second conveyor line 2002. Both the first and second conveyor lines are commercially available and consist of a power system, a drive chain, a toothed conveyor belt, a guide device, a tensioning device, and an electrical control system. The power system drives the drive chain to rotate the toothed conveyor belt, thus conveying materials. It only needs to meet the requirements for conveying waste materials; the model is universal and will not be elaborated upon or limited here. To clearly illustrate the internal components of the first and second conveyor lines 2001 and 2002, Figure 4 This is a schematic diagram showing the state when the toothed conveyor belts in the first conveyor line 2001 and the second conveyor line 2002 are hidden.

[0050] This utility model innovatively adds a waste conveying system 2, establishing an intelligent waste collection and conveying system through the efficient linkage of the first conveyor line 2001 and the second conveyor line 2002. This system automatically captures and conveys waste materials during laser cutting of the sheet metal, achieving centralized waste management. Compared to the traditional method of letting waste scatter on the ground, this design significantly reduces the time and costs required for equipment cleaning and maintenance. Simultaneously, it organically integrates sheet metal conveying, cutting, and waste collection processes, powerfully promoting the automation of the processing flow and significantly improving overall production efficiency.

[0051] Main references Figure 4 , Figure 5 , Figure 7 , Figure 15 As shown, the conveying assembly 5 includes: bearing seats 5001 and conveying rollers 5002. The bearing seats 5001 are arranged in two rows, and the two rows of bearing seats 5001 are arranged in a front-to-back manner on two crossbeams 1002. The conveying rollers 5002 are rotatably arranged between the two front-to-back bearing seats 5001. The conveying assembly 5 can convey the plate and assist the plate to move to a suitable position, and then position it at the blocking assembly 9, the guide assembly 7, and the positioning cylinder 4.

[0052] Main references Figure 6 , Figure 7As shown, the guide assembly 7 includes a fixed base 7001 and a guide wheel 7002. The fixed base 7001 is fixedly mounted on the crossbeam 1002. The guide wheel 7002 is rotatably mounted on the top of the fixed base 7001 via a bearing. The guide wheel 7002 adopts a rotatable structure, utilizing rolling friction characteristics instead of traditional sliding friction during the precise guiding and limiting of the plate side. This optimized design effectively reduces the contact resistance between the plate side and the surface of the guide wheel 7002, not only reducing mechanical damage to the plate surface but also improving the stability and guiding accuracy of the conveying process, ultimately achieving a significant optimization of the overall transmission efficiency.

[0053] This solution also includes lifting cylinders 3, of which multiple lifting cylinders 3 are installed vertically on the crossbeam 1002; a support component 6 is provided at the top output end of the lifting cylinder 3; this utility model constructs a plate lifting device through the coordinated cooperation of the support component 6 and the lifting cylinders 3. With the help of this device, the plates on the conveying platform conveying component 5 can be smoothly lifted, detaching them from the surface of the conveying platform conveying component 5, and processed in a suspended state. This suspended processing method can effectively avoid damage to the components of the conveying platform conveying component 5 during cutting operations, ensuring that the conveying platform conveying component 5 can still carry out subsequent plate conveying work normally after completing the processing of the current batch of plates, thereby ensuring the stability and reliability of continuous equipment operation.

[0054] Main references Figure 10 As shown, the supporting component 6 includes: a connecting frame 6001, a mounting base 6002, a positioning groove 6003, and a toothed plate 6004. The connecting frame 6001 is a rectangular frame structure and is fixedly installed on the top output end of the lifting cylinder 3. The mounting base 6002 has two rows, and the two rows of mounting bases 6002 are installed on the connecting frame 6001 in a front-to-back manner. Each mounting base 6002 is U-shaped. The positioning grooves 6003 are symmetrically opened on the surface of each mounting base 6002. The toothed plate 6004 is inserted into the positioning grooves 6003 on the front-to-back mounting bases 6002. The top of the toothed plate 6004 is provided with toothed grooves at equal intervals.

[0055] The 6004 toothed plate, while providing stable support for the plate, significantly reduces the contact area with the lower surface of the plate through optimized contact structure. This overcomes the spatial limitations of traditional support structures, freeing up ample working space for the laser cutting process, ensuring that the cutting beam can penetrate the plate without obstruction, effectively improving the operability and processing efficiency of the cutting process, and guaranteeing efficient cutting operations.

[0056] The conveyor roller 5002 rotates synchronously via a drive mechanism 8. The drive mechanism 8 includes a drive motor 8001, a third synchronous sprocket 8007, a first synchronous sprocket 8002, a second synchronous sprocket 8003, a second synchronous chain 8005, and a housing 8006. The drive motor 8001 is located at the bottom of the frame 1. The third synchronous sprocket 8007 is mounted at the output end of the drive motor 8001. The first synchronous sprocket 8002 is fixedly mounted at both ends of the conveyor roller 5002. The second synchronous sprocket 8003 is fixedly mounted at both ends of the conveyor roller 5002. The second synchronous chain 8005 consists of two parts, with half of the second synchronous chain 8005 meshing with two adjacent first synchronous sprockets 8002, and the other half meshing with two adjacent second synchronous sprockets 8003. The housing 8006 is fixedly mounted on the mounting bracket 1004.

[0057] This invention utilizes an integrated drive mechanism 8, employing synchronous transmission technology to achieve coordinated control of all conveying rollers 5002. Under the action of this drive system, each conveying roller 5002 can rotate in unison with consistent direction and speed, thereby generating continuous and stable conveying power, enabling automated transfer of the sheet material on the conveying platform assembly 5. By using a single power source to drive multiple conveying rollers 5002 to work together, the synchronization and reliability of the transmission system are greatly improved, effectively ensuring a smooth and stable sheet material conveying process.

[0058] In this configuration, the first synchronous chain 8004 replaces the second synchronous chain 8005 on one of the two adjacent second synchronous sprockets 8003, and meshes with the two second synchronous sprockets 8003 on the same set of second synchronous sprockets 8003. The first synchronous chain 8004 also meshes with the third synchronous sprocket 8007. The third synchronous sprocket 8007 is driven to rotate by the activated drive motor 8001, which in turn drives the first synchronous chain 8004 to rotate with the two second synchronous sprockets 8003, thereby enabling the rotation of the two conveying rollers 5002. Compared to the method where the drive motor 8001 is directly connected to one of the conveying rollers 5002, the transmission is more stable and more conducive to the uniform rotation of each conveying roller 5002.

[0059] Main references Figure 8 and Figure 9As shown, the blocking assembly 9 includes: a blocking cylinder 9001, a base 9002, a rotating shaft 9003, a blocking block 9004, and a roller 9005. The blocking cylinder 9001 is fixedly mounted on the longitudinal frame 1003; the base 9002 is fixedly connected to the longitudinal frame 1003; the rotating shaft 9003 is rotatably disposed within the inner cavity of the base 9002; the blocking block 9004 is fixedly mounted on the rotating shaft 9003, and the blocking block 9004 is triangular in shape. The output end of the blocking cylinder 9001 is connected to the blocking block 9004; the roller 9005 is rotatably disposed on the blocking block 9004.

[0060] Without adjusting the height of roller 9005, a fixed connection between blocking cylinder 9001 and blocking block 9004 is sufficient. Roller 9005 can meet the end-limiting requirements of most sheet metal applications. When the height of roller 9005 needs to be adjusted to adapt to the positioning requirements of different subsequent sheet metal ends, the output end of blocking cylinder 9001 is slidably connected to blocking block 9004. That is, a groove is provided on the lower surface of blocking block 9004 for the sliding cavity of the output end of blocking cylinder 9001. By raising and lowering the output end of blocking cylinder 9001, its output end can slide along the inner cavity of the groove on the lower surface of blocking block 9004, driving blocking block 9004 to rotate about shaft 9003. This is existing technology. Other connection methods can also be used to achieve the relative sliding connection between the output end of blocking cylinder 9001 and the lower surface of blocking block 9004, as long as they meet the requirement of driving blocking block 9004 to rotate. These methods will not be elaborated or limited here.

[0061] When adjusting the height of roller 9005 to adapt to the positioning requirements of different subsequent plate ends, the bottom end of blocking block 9004 is moved by the activated blocking cylinder 9001, so that blocking block 9004 rotates around the rotating shaft 9003, thereby adjusting the height of roller 9005.

[0062] The roller 9005 in this invention can achieve precise positioning of the end of the sheet material. In addition, through the rotational connection structure between the roller 9005 and the rotating shaft 9003, the height of the roller 9005 can be flexibly adjusted, so that the roller 9005 can be adaptively adjusted according to the change of sheet material thickness, ensuring that reliable end positioning can be obtained for sheets of different specifications during processing, effectively improving the equipment's adaptability and positioning accuracy for processing diverse sheets of material.

[0063] It is worth noting that this equipment is equipped with an external PLC controller. This PLC controller can control the start and stop of all electrical components in the equipment and can preset the timing of the operation of various electrical components, so that the actions of each component are smooth and the material conveying and positioning are continuous. This is existing technology and will not be elaborated or limited here. In addition, the cutting station for laser cutting is set above this equipment, and the material after being positioned by the blocking component 9 of this equipment is finally laser cut.

[0064] In this application, the lifting cylinder 3, positioning cylinder 4, and blocking cylinder 9001 are all commonly used self-locking cylinders on the market. Their output ends can stop at any position and be locked. As long as they meet the usage requirements, their models will not be described or limited here. The drive motor 8001 is a commonly used self-locking motor on the market with a lockable output end. When it stops, its output end can be self-locked and will not rotate under external force. The drive motor 8001 is also a commonly used forward and reverse motor on the market. Its output end can rotate in the forward or reverse direction according to the usage requirements. As long as it meets the above usage requirements, it will not be limited here. The drive motor 8001, the first synchronous sprocket 8002, and the third synchronous sprocket 8007 are common sprockets on the market. They can form a stable transmission system with the second synchronous sprocket 8003. The assembly parameters of the drive motor 8001, the first synchronous sprocket 8002, and the second synchronous sprocket 8003 can meet the usage requirements. As long as they meet the usage requirements, they will not be described or limited here. The model of the above-mentioned existing components will not be limited or described in detail here.

[0065] The working principle of a laser cutting conveyor line in this embodiment is as follows:

[0066] The sheet material to be processed is placed on the upper surface of several conveying components 5. The drive motor 8001, when turned on, drives the third synchronous sprocket 8007 to rotate counterclockwise, causing the first synchronous chain 8004 to drive the two second synchronous sprockets 8003 meshing on its outer wall to rotate counterclockwise in the same direction. At this time, the two corresponding sets of conveying rollers 5002 inside the housing 8006 rotate synchronously under the drive of the second synchronous sprockets 8003, thereby driving the first synchronous sprocket 8002 and the second synchronous chain 8003 connected to the ends of the two conveying rollers 5002. The wheels 8003 rotate synchronously. Since the first synchronous sprocket 8002 and the second synchronous sprocket 8003 on the two adjacent sets of conveyor rollers 5002 are connected by the second synchronous chain 8005 respectively, when one set of conveyor rollers 5002 rotates, it can drive all conveyor rollers 5002 to rotate in the same direction and synchronously, so as to realize that the plate gradually moves to the left on the upper surface of the conveyor roller 5002; until the plate moves to the left to the contact roller 9005, the left end of the plate is positioned under the action of the roller 9005.

[0067] The front sidewall of the plate is driven by the activated positioning cylinder 4, causing the plate to move backward along the upper surface of the conveying roller 5002 until the rear sidewall of the plate is in contact with the guide wheel 7002 set on the rear side. Under the guiding and limiting action of the guide wheel 7002 set in a row on the rear side, and with the drive of the output end of the positioning cylinder 4, the plate on the conveying roller 5002 can be aligned and positioned. At this time, the plate remains stable under the joint positioning action of the blocking component 9, the guiding component 7, and the positioning cylinder 4.

[0068] The lifting cylinder 3 drives the connecting frame 6001 to rise, causing the mounting base 6002 and each toothed plate 6004 on the connecting frame 6001 to move upward synchronously until the toothed plate 6004 contacts and continues to support the lower surface of the plate, causing the plate to gradually rise until it is detached from the surface of the conveying roller 5002. Since the plate has been corrected and limited during the conveying process, the plate after being lifted upward by the lifting cylinder 3 and the supporting component 6 still maintains an upright posture so that the subsequent laser cutting equipment can accurately cut the plate.

[0069] After the laser cutting equipment cuts the sheet metal, the waste material falls downward onto the first conveyor line 2001. The first conveyor line 2001 transports the waste material from left to right to the second conveyor line 2002. Under the action of the second conveyor line 2002, which transports the waste material from back to front, the waste material is uniformly transported and collected to the front output end of the second conveyor line 2002. A collection box or collection bag or other collection device can be set at the front output end of the second conveyor line 2002 to realize the unified treatment and recycling of waste material.

[0070] In this invention, the side constraint guiding system, in conjunction with the end limiting structure, enables three-dimensional positioning control of the sheet metal, real-time trajectory correction, avoidance of positioning errors, improvement of cutting accuracy, and ensures efficient and stable operation of laser cutting. The automated waste collection and conveying system automatically transports waste generated during laser cutting of the sheet metal, achieving centralized waste processing, significantly shortening equipment cleaning and maintenance cycles, and effectively integrating sheet metal conveying, cutting, and waste collection, thereby significantly improving the automation level and production efficiency of the overall processing flow. The rotating guide wheel 7002 replaces sliding friction with rolling friction, reducing frictional resistance and minimizing sheet metal wear. The integrated drive mechanism 8 enables linkage control of the conveyor roller 5002, improving transmission synchronization and reliability, and ensuring smooth and stable conveying of the sheet metal. The sheet metal lifting function, constructed by the support component 6 and the lifting cylinder 3, allows the sheet metal to be processed in mid-air, avoiding damage to the conveyor platform components and ensuring stable continuous operation of the equipment. The toothed plate 6004 reduces the contact area, reserves cutting space, and improves the feasibility and efficiency of the cutting process. The roller 9005 can accurately position the end of the sheet metal and can flexibly adjust its height to adapt to sheet metal of different thicknesses, improving the equipment's adaptability and positioning accuracy for processing diverse sheet metals.
