Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a high-speed, high-precision laser cutting equipment based on PLC control. Background Technology

[0002] High-speed, high-precision laser cutting equipment based on PLC control is an industrial-grade automated precision machining equipment. With PLC as the control core, it combines laser technology and a precision motion system, and is specifically designed for high-speed, high-precision, stable and reliable laser cutting of various materials. Compared with ordinary laser cutting machines, it has a faster cutting speed while ensuring extremely high precision. It is suitable for mass production of precision parts and can cut straight lines, round holes, and complex irregular shapes. The cut is smooth and burr-free, requiring no secondary grinding. It can quickly switch cutting programs and supports multi-variety, small-batch or large-batch production without changing molds, flexibly meeting different needs.

[0003] A Chinese patent with publication number CN110355483A discloses a laser cutting device, including a laser cutting mechanism and a frame. The laser cutting mechanism is mounted on a gantry support, which is located above the frame and can move horizontally along the X and Y axes. The frame has a tube-plate fixing mechanism that is deformable. Initially, it is flat and used to support and fix the sheet metal during cutting. When processing tubes, it is deformed into an arc shape adapted to the tube by the weight of the tube. When processing sheet metal, the sheet metal can be placed directly on the frame. When processing tubes, the tube-plate fixing mechanism does not need to be disassembled and can be used directly. The tube's own weight causes the tube-plate fixing mechanism to compress an arc-shaped groove, thereby fixing the tube and preventing its displacement. The operation is simple and convenient, and the cost is low.

[0004] In current high-speed, high-precision laser cutting equipment based on PLC control, after the laser cutting process is completed, the workpiece often adheres to or stacks with waste and leftover materials. Because the equipment generally lacks automated separation, positioning, and temporary storage mechanisms, manual sorting and cleaning are required. This not only significantly increases the labor intensity of operators but also easily leads to a decline in the quality of finished products.

[0005] Therefore, the present invention provides a high-speed, high-precision laser cutting device based on PLC control. Summary of the Invention

[0006] The purpose of this invention is to provide a high-speed, high-precision laser cutting device based on PLC control, so as to solve the problems mentioned in the background art.

[0007] A high-speed, high-precision laser cutting equipment based on PLC control includes a worktable, a protective shell fixedly mounted on the top of the worktable, a PLC controller mounted on the protective shell, a support plate fixedly mounted on the worktable, a laser cutting component mounted on the side of the support plate, an adjustment mechanism for adjusting the position of the laser cutting component mounted on the support plate, a first support frame embedded inside the worktable, a feeding mechanism mounted inside the first support frame, and a power box fixedly mounted on the side of the first support frame, with a power mechanism mounted inside the power box. The workbench has a concave groove inside, and an installation groove inside the workbench is connected to the concave groove. A box is fixedly installed inside the concave groove. A side plate is fixedly installed on the top of the box. Holes are arranged in an array on the side plate. A sliding groove is provided inside the box. A waste bin is provided inside the sliding groove. A magnetic plate is fixedly installed on the side of the waste bin. A frame is provided inside the workbench. A drive mechanism is provided inside the frame.

[0008] By adopting the above scheme, when using a high-speed, high-precision laser cutting equipment based on PLC control to continuously feed and precisely cut metal materials, the movement of the power mechanism drives the movement of the feeding mechanism, which facilitates the feeding of metal materials. The position of the laser cutting component can be adjusted by the adjustment mechanism, and the movement of the laser cutting component can process the metal materials waiting to be cut. The cut workpiece will fall into the concave groove, and the side plate supports the fallen workpiece. When the power mechanism moves, it will cause the drive mechanism to move, which will cause the side plate and the unloading groove to vibrate. The vibration of the side plate and the unloading groove will assist the movement of the workpiece for unloading, improving efficiency. When the workpiece is unloaded, any impurities adsorbed on the workpiece will vibrate and fall off. The adsorbed impurities will fall into the waste bin for storage through the holes, improving the quality of the workpiece. Pulling the waste bin will move it to the outside, and the impurities stored in the waste bin can be processed. After the impurities stored in the waste bin are removed, the waste bin is reset. The position of the waste bin is limited by the cooperation of the magnetic plate.

[0009] Preferably, a warning light is fixedly installed on the top of the protective shell, and a sealed door is connected to the front of the protective shell by a hinge; The laser cutting assembly includes a mounting block, a laser generator, and a laser cutting head. The laser generator is fixed on the support block, and the laser cutting head is located below the support block and connected to the laser cutting head.

[0010] By adopting the above scheme, the protective shell protects the working area. After the metal strip to be processed is moved directly under the laser cutting head, the laser generator works to process and cut the metal strip in conjunction with the laser cutting head.

[0011] Preferably, the adjustment mechanism includes a first motor, a first screw, a concave frame, a second motor, and a second screw. The first motor is fixed inside the support plate. The first screw is rotatably disposed inside the support plate, and its end is connected to the first motor.

A second corrugated tube is sleeved on the second screw, and its end is fixedly connected to the inner wall of the support block and the concave frame, respectively.

[0012] By adopting the above scheme, controlling the operation of motor one will drive the rotation of screw one. When screw one rotates, the vertical position of the concave frame and the vertical position of the laser cutting head can be adjusted. Controlling the operation of motor two will drive the rotation of screw two. The movement of screw two can adjust the position of the support block, and thus the horizontal position of the laser cutting head can be adjusted, thus improving flexibility.

[0013] Preferably, the feeding mechanism includes a rotating roller, an adjusting screw, a second support frame, a threaded cylinder, and a limiting roller. The rotating roller array is rotatably disposed inside the first support frame, the second support frame is symmetrically disposed inside the first support frame, the adjusting screw is rotatably disposed inside the first support frame, the threaded cylinder is fixed on the second support frame, and the adjusting screw is threadedly connected to the threaded cylinder. The limiting roller corresponding to the rotating roller is rotatably disposed on the second support frame. A guide shaft passes through the second support frame, and the end of the guide shaft is fixedly connected to the inner wall of the first support frame.

[0014] By adopting the above scheme, rotating the adjusting screw will adjust the position of the second support frame through the threaded cylinder. The movement of the second support frame will adjust the position of the limiting roller. According to the size of the metal strip, the limiting roller is moved to the predetermined position. The rotation of the roller facilitates the feeding of the metal strip and makes it convenient to feed metal strips of different sizes.

[0015] Preferably, the power mechanism includes a transmission wheel, a reducer, and a power motor. The transmission wheel corresponding to the end of the rotating roller is rotatably disposed inside the power box, and the center position of the transmission wheel is fixedly connected to the end of the rotating roller. Adjacent transmission wheels are connected by belt drive. The reducer is fixed on the power box, and the output end of the reducer is fixedly connected to the center position of the corresponding transmission wheel. The power motor is fixed inside the worktable, and the output end of the power motor is fixedly connected to the input end of the reducer.

[0016] By adopting the above scheme, controlling the power motor to work will drive the reducer to move. When the reducer moves, it will drive the corresponding transmission wheel to rotate. The belt will cause the adjacent transmission wheel to rotate. When the transmission wheel rotates, it will cause the rotating roller to rotate. The rotation of the rotating roller and the limit roller cooperate to facilitate the feeding and processing of metal strip.

[0017] Preferably, the mounting slot is provided with a material discharge slot, which is inclined, and the material discharge slot and the housing are provided with grooves in an array.

[0018] By adopting the above solution, the feeding trough and the box provide installation space for the groove.

[0019] Preferably, the drive mechanism includes a power shaft, a rotating disk, a driven wheel, a through groove, and a push plate. The power shaft is rotatably disposed inside the frame. The rotating disk is fixed to the end of the power shaft. The driven wheel is fixed on the power shaft and is connected to the transmission wheel via a belt drive. The through groove is disposed on the frame and is connected to the power box. One end of the push plate is movably connected to the rotating disk.

[0020] By adopting the above scheme, when the transmission wheel rotates, the drive shaft will rotate through the cooperation of the belt and the driven wheel. When the drive shaft rotates, it will drive the rotating disk to rotate, and when the rotating disk rotates, it will drive the push plate to move.

[0021] Preferably, a connecting plate is movably connected to the other end of the push plate, a compression groove is fixedly provided inside the frame, a compression block is provided inside the compression groove, and the end of the connecting plate is fixedly connected to the center position of the compression block. A conveying pipe is connected to one end of the compression groove.

[0022] By adopting the above scheme, the rotation of the rotating disk, in conjunction with the push plate, will drive the connecting plate to move repeatedly. When the connecting plate moves, it will drive the compression block to move synchronously. The movement of the compression block will compress the air inside the compression tank, and the compressed air will be transmitted through the conveying pipe.

[0023] Preferably, a load-bearing plate is fixedly mounted on the connecting plate, a movable box is fixedly mounted on the load-bearing plate, a guide rod is fixedly mounted inside the movable box, a sliding block is mounted inside the movable box, and the guide rod passes through the sliding block. A drive spring is fixedly mounted inside the load-bearing plate, and the other end of the drive spring is fixedly connected to the sliding block. A guide ring is fixedly mounted inside the load-bearing plate, and a striking post passes through the guide ring. The end of the striking post is fixedly connected to the sliding block, and one end of the striking post extends to one side of the groove.

[0024] By adopting the above scheme, when the connecting plate moves repeatedly, it will drive the movable box to move through the load-bearing plate. When the movable box moves, it will drive the striking column to move synchronously. The end of the striking column is arc-shaped with an array of grooves. Through the cooperation of the grooves, the striking column will be driven to move. When the striking column moves, it will be guided by the cooperation of the guide ring and the sliding block, so that the striking column moves smoothly. The driving spring can reset the striking column. Repeatedly, the side plate and the unloading groove will vibrate, which will facilitate the unloading of the workpiece.

[0025] Preferably, the front of the workbench is provided with a strip groove, a limit rod is provided inside the strip groove, a third support frame is sleeved on the limit rod, a positioning bolt is threaded onto the third support frame, a limit frame is fixedly provided on the third support frame, a diversion groove is embedded inside the limit frame and the diversion groove is connected to the conveying pipe, and spray holes are arrayed on the diversion groove and a filter screen is provided inside the spray holes.

[0026] By adopting the above scheme, the position of the limiting frame is adjusted according to the metal strip. After the limiting frame moves to the predetermined position, the positioning bolt is rotated so that it contacts the surface of the limiting rod, which limits the position of the limiting frame and allows the metal strip to pass through it. The limiting frame can limit and guide the metal strip, effectively preventing curling during the feeding of the metal strip. Compressed air is transmitted through the conveying pipe and enters the diversion tank. The diversion tank is symmetrically arranged, and the airflow is directed to the surface of the metal strip through the spray holes, thereby cleaning the metal strip and ensuring the quality of the workpiece.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. The high-speed, high-precision laser cutting equipment based on PLC control described in this invention, through the addition of side plates and a waste bin, can efficiently remove impurities adsorbed on the surface of the workpiece, and simultaneously assist in workpiece unloading. After cutting, the workpiece falls into a concave groove, supported by the side plates. When the movable box moves, it synchronously drives the displacement of the striking column; the end of the striking column is arc-shaped, cooperating with the arrayed grooves to drive the striking column to reciprocate. During the movement of the striking column, precise guidance is achieved through the synergistic action of the guide ring and the sliding block, ensuring smooth movement. The drive spring provides the reset power for the striking column. This cycle causes the side plates and the unloading groove to vibrate at high frequency. The vibration of the side plates and the unloading groove can, on the one hand, assist the smooth sliding and unloading of the workpiece, improving unloading efficiency; on the other hand, it can cause impurities adsorbed on the surface of the workpiece to fall off due to vibration. The impurities fall into the waste bin below through preset holes for storage, effectively improving the quality of the finished workpiece. When impurities accumulate to a certain amount in the waste bin, they can be pulled out to facilitate centralized cleaning of the internal impurities. After cleaning, the waste bin is reset, and precise positioning is achieved through the magnetic adsorption effect of the magnetic plate to ensure the stability of equipment operation.

[0028] 2. The high-speed, high-precision laser cutting equipment based on PLC control described in this invention can achieve source cleaning treatment of metal strips through the setting of compression grooves and diversion grooves, effectively ensuring the processing quality of workpieces. When the power shaft rotates, it drives the rotating disk to rotate synchronously. The rotating disk drives the connecting plate to reciprocate through the cooperation of the push plate. During the movement of the connecting plate, it drives the compression block to move synchronously, compressing the air inside the compression groove. The compressed air is transported to the symmetrically set diversion grooves through the conveying pipe, and then the airflow is guided to the surface of the metal strip through the spray holes, thereby cleaning the metal strip and ensuring the quality of the finished workpiece from the source.

[0029] 3. The high-speed, high-precision laser cutting equipment based on PLC control described in this invention can stably feed and guide the metal strip by setting a limiting frame, avoiding bending and curling of the metal strip and ensuring the processing quality of the workpiece. After adjusting the limiting frame to the predetermined position, tightening the positioning bolts to make it press against the surface of the limiting rod can complete the position limiting of the limiting frame. When the metal strip passes through the limiting frame for feeding, the limiting frame limits and guides it, which can effectively avoid problems such as curling and deviation of the metal strip during the feeding process, and further ensure the quality of the finished workpiece.

[0030] 4. The high-speed, high-precision laser cutting equipment based on PLC control described in this invention, by setting rotating rollers and limiting rollers, can adapt to the feeding of metal strips of different sizes. Rotating the adjusting screw, in cooperation with the threaded cylinder, adjusts the position of the second support frame, thereby driving the limiting rollers to complete the position adjustment. According to the actual specifications of the metal strip, the limiting rollers can be adjusted to the appropriate position, cooperating with the rotating rollers to achieve stable feeding of the metal strip. This structure can flexibly adapt to metal strips of different sizes, effectively improving the equipment's flexibility and adaptability. Attached Figure Description

Adjusting the position of the limiting frame 58 according to the metal strip position, after the limiting frame 58 moves to the predetermined position, rotating the positioning bolt 57 causes the positioning bolt 57 to move and contact the surface of the limiting rod 55, thus limiting the position of the limiting frame 58, allowing the metal strip to pass through the limiting frame 58. The limiting frame 58 can limit and guide the metal strip, effectively preventing curling during the feeding of the metal strip. Compressed air is transmitted through the conveying pipe 46 and enters the diversion trough 59. The diversion trough 59 is symmetrically arranged, and the airflow through the spray holes 60 will cause the air to flow to the surface of the metal strip, thereby cleaning the metal strip and ensuring the quality of the workpiece.

[0044] Working Principle: First, when using a high-speed, high-precision laser cutting equipment controlled by a PLC to continuously feed and precisely cut metal materials, the position of the limiting frame 58 is adjusted according to the metal strip. After the limiting frame 58 moves to the predetermined position, the positioning bolt 57 is rotated, causing it to contact the surface of the limiting rod 55, thus limiting the position of the limiting frame 58. This allows the metal strip to pass through the limiting frame 58. The limiting frame 58 guides and limits the metal strip, effectively preventing curling during feeding. Rotating the adjusting screw 23, in conjunction with the threaded cylinder 25, adjusts the position of the second support frame 24. The movement of the second support frame 24 adjusts the position of the limiting roller 27. The position of the limiting roller 27 is adjusted according to the size of the metal strip. The laser cutting assembly moves to a predetermined position, and the rotating roller 18 facilitates the feeding of metal strips of different sizes, improving flexibility. The control motor 22 drives the reducer 21, which in turn rotates the corresponding drive wheel 20. This rotation, via a belt, causes adjacent drive wheels 20 to rotate, which in turn rotates the rotating roller 18. The rotating roller 18, in conjunction with the limit roller 27, facilitates the feeding and processing of the metal strip. The position of the laser cutting assembly can be adjusted via an adjustment mechanism. The movement of the laser cutting assembly allows for the processing of metal materials. The cut workpiece falls into the concave groove 28, where it is supported by the side plate 31. As the drive wheel 20 rotates, the belt... The belt and driven wheel 40 work together to rotate the drive shaft 38. The rotation of the drive shaft 38 drives the rotating disk 39 to rotate, which in turn drives the push plate 42. The rotation of the rotating disk 39, through the push plate 42, causes the connecting plate 44 to move repeatedly. The movement of the connecting plate 44 causes the compression block 45 to move synchronously. The movement of the compression block 45 compresses the air inside the compression groove 43. This compressed air is then transported through the conveying pipe 46 and enters the diversion groove 59. The diversion groove 59 is symmetrically arranged, and through the spray holes 60, the airflow is directed towards the surface of the metal strip, thus cleaning the metal strip and ensuring the quality of the workpiece. The repeated movement of the connecting plate 44, through the load-bearing plate 48, drives the movable box 49 to move. The timing of the movement causes the striking column 52 to move synchronously. The end of the striking column 52 is arc-shaped with an array of grooves 61. The grooves 61 engage to drive the striking column 52 to move. As the striking column 52 moves, it is guided by the guide ring 53 and the sliding block 51, ensuring smooth movement. The drive spring 50 can reset the striking column 52. This repeated movement causes the side plate 31 and the feeding trough 36 to vibrate. The vibration of the side plate 31 and the feeding trough 36 assists in the movement and feeding of the workpiece, improving efficiency. During workpiece feeding, any impurities adsorbed on the workpiece will vibrate and fall off. These impurities will then fall through the holes 32 and enter the waste bin 34 for storage, improving the quality of the workpiece. Pulling the waste bin 34 moves it to the outside.The waste bin 34 can then be used to process the stored impurities. After the impurities stored inside the waste bin 34 are removed, the waste bin 34 is reset, and the magnetic plate 35, in conjunction with it, limits the position of the waste bin 34.
