Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a laser chamfering device. Background Technology

[0002] In the field of laser processing technology, using lasers to chamfer the edges of sheet materials is a highly efficient and precise manufacturing process. This process uses a high-energy-density laser beam to ablate or melt the material along the edge of the sheet to remove sharp edges and form specified bevels or rounded corners. It is widely used to improve the aesthetics, assembly performance, and safety of parts. To achieve automated processing, the equipment usually integrates vision positioning and multi-axis drive systems. An industrial camera identifies the outline and position of the sheet material, and then the laser head moves precisely along the planned path. In actual operation, to ensure the stability and positional accuracy of the sheet material under the action of the laser, a negative pressure adsorption method is commonly used to fix the workpiece from the bottom. That is, the hollow support platform is connected to the air extraction equipment, and the sheet material is firmly held in place by the air suction holes.

[0003] However, existing laser chamfering equipment of this type has an unavoidable problem during long-term operation: a large amount of fine dust and debris generated during the chamfering process is easily sucked into the inner cavity of the support platform by the adsorption airflow. These wastes gradually accumulate in the adsorption pipes, causing the airflow channels to narrow or even block, resulting in a continuous decrease in negative pressure adsorption force. This may eventually cause the sheet metal to loosen or shift during processing, resulting in loss of chamfering accuracy or even scrapping of the workpiece. Since the adsorption air path is mostly a closed or semi-closed narrow space, once a blockage occurs, cleaning often requires interrupting production and disassembling related components. The maintenance work is cumbersome and time-consuming, significantly reducing the overall efficiency of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a laser chamfering device that addresses the problem in the prior art where, once the adsorption gas path becomes blocked, cleaning often requires interrupting production, disassembling related components, and is cumbersome and time-consuming to maintain, significantly reducing the overall efficiency of the equipment.

[0005] To solve the above problems, one technical solution adopted by the present invention is to provide a laser chamfering device, comprising: A base frame is provided with a controller. A protective cover is installed on the top of the base frame. An industrial camera is installed inside the protective cover. A laser chamfering machine is installed on the base frame inside the protective cover. The base frame is provided with a drive structure for moving the industrial camera and the laser chamfering machine. Both the industrial camera and the laser chamfering machine are electrically connected to the controller. The base has feet that are slidably mounted on both sides of the top of the frame. Multiple support members are rotatably mounted between the two feet. Each support member has a hollow structure and multiple air intake holes communicating with the outside are opened on the top of the support member. Multiple fixed seats are fixedly mounted on one side of the foot. Each fixed seat has a hollow structure communicating with the support member. Each fixed seat has an air intake connector connected to its top. Each air intake connector is connected to each other through a hollow pipe. Each support member has a rotatable double-acting screw rod inside. Each double-acting screw rod has two relatively movable scrapers threadedly connected to it. The edge of each scraper is in contact with the inner contour of the corresponding support member.

[0006] Furthermore, the drive structure includes a first transverse slide rail, a support base, a second transverse slide rail, a longitudinal slide rail, and a vertical slide rail. The first transverse slide rail is installed on the top of the protective cover. The industrial camera is slidably mounted on the first transverse slide rail. Support bases are fixedly installed on both sides of the top of the base frame. The second transverse slide rail is installed on the top of each of the two support bases. A longitudinal slide rail is slidably installed between the two second transverse slide rails. A vertical slide rail is slidably installed on the longitudinal slide rail. The laser chamfering machine is fixedly installed at the bottom of the slider of the vertical slide rail. The first transverse slide rail, the second transverse slide rail, the longitudinal slide rail, and the vertical slide rail are all electric slide rails, and the first transverse slide rail, the second transverse slide rail, the longitudinal slide rail, and the vertical slide rail are all electrically connected to the controller.

[0007] Furthermore, it also includes a transmission gear and a rack, with a transmission gear fixedly connected to one end of each of the bidirectional lead screws, and a rack fixedly installed on one side of the top of the base frame, with each of the transmission gears meshing with the rack.

[0008] Furthermore, it also includes a connecting seat, a drive motor, a drive gear, and a rack. A connecting seat is installed on the top of each of the two feet, and a drive motor is installed on each of the two connecting seats. The two drive motors are electrically connected to the controller. A drive gear is installed on the output shaft of each of the two drive motors. A rack is fixedly installed on both sides of the top of the base frame, and the two drive gears mesh with the corresponding racks.

[0009] Furthermore, it also includes a stop block, a return spring, and a filter screen. Each of the carrier members has multiple discharge holes on both sides. Each of the carrier members has a stop block slidably disposed on both sides. Each stop block covers the discharge hole on the corresponding side. Each stop block is fixedly connected to the corresponding carrier member with a return spring. Filter screens are installed on the side of the two stops blocks on the same carrier member that are close to each other.

[0010] Furthermore, it also includes a servo motor, full gears, and idler gears. A servo motor is mounted on one side of the foot, and the servo motor is electrically connected to the controller. The output shaft of the servo motor is fixedly connected to a support member. A full gear is fixedly mounted on one side of each support member. Multiple idler gears are rotatably mounted on one side of the foot. Each full gear and each idler gear are alternately spaced and mesh with each other.

[0011] Furthermore, it also includes a striking block, with each of the bidirectional lead screws having a striking block connected to its center via an elastic element.

[0012] Furthermore, it also includes a discharge box, guide rods, return springs, and collection boxes. Multiple guide rods are slidably installed on the top side of the base frame, and discharge boxes are slidably arranged between the guide rods on the same side. Return springs are installed between the discharge boxes and the guide rods. Multiple collection boxes are placed on the top of the base frame, and the collection boxes are all located directly below the outlet of the discharge box.

[0013] Furthermore, it also includes pulleys and a collection frame. The top of each unloading box is rotatably connected to multiple pulleys, and the top of the base frame is equipped with a collection frame for collecting waste.

[0014] Compared with the prior art, the present invention has the following main advantages: 1. This invention, by setting up a scraper that cooperates with the bidirectional lead screw inside the support component, automatically triggers the meshing transmission of the transmission gear and rack during the retraction of the foot seat, driving the scraper to move towards both ends against the inner wall of the support component. At the same time, the striking block connected by the elastic element swings under the centrifugal force of rotation, shaking off the debris attached to the inner wall, thereby achieving the effect of actively cleaning the adsorption gas path and solving the problem of easy blockage of the adsorption pipe in existing equipment, which leads to a decrease in adsorption force.

[0015] 2. By fixing the filter screen to the side of the baffle and moving with the baffle, the filter screen continuously filters and intercepts the exhaust airflow during the process of waste discharge through the open discharge hole, thereby preventing waste from being sucked back into the external air extraction equipment through the fixed seat and air intake connector, and effectively protecting the air extraction system from pollution and damage.

[0016] 3. This invention uses a servo motor in conjunction with alternating meshing of full gears and idler gears to drive all load-bearing components to rotate and tilt synchronously after the plate is unloaded. This causes residual waste on the surface of the load-bearing components to fall into the collection frame under gravity. At the same time, the centrifugal swing of the striking block during rotation continuously strikes the inner wall of the load-bearing components, and the unloading box is reset by the shaking under the action of the return spring. This achieves the effect of completely dumping and collecting processing waste and avoiding the accumulation of debris inside the unloading box. Attached Figure Description

Inside the protective cover 2 is the industrial camera 4 for recording and collecting information from the sheet metal. The laser chamfering machine 6 for chamfering the sheet metal is located inside the protective cover 2 on the base frame 1. The base frame 1 has a drive structure for moving the industrial camera 4 and the laser chamfering machine 6. Both the industrial camera 4 and the laser chamfering machine 6 are electrically connected to the controller 101.

The support component 8 is a hollow structure with multiple air intake holes 9 on its top that communicate with the outside. Multiple fixed seats 12 are fixedly installed on the front of the front foot 7, and a sealing ring 11 is provided at the connection between the foot 7 and the fixed seat 12 to ensure a sealed connection between the foot 7 and the fixed seat 12. The fixed seat 12 is a hollow structure that communicates with the support component 8. Each fixed seat 12 is connected to and communicates with an air intake connector 13 on its top. Each air intake connector 13 is connected to each other through a hollow pipe and is connected to and communicates with an external air extraction device. A two-way screw rod 14 is rotatably installed inside each support component 8. Two relatively movable scraper frames 15 are threadedly connected to each two-way screw rod 14. The edge of each scraper frame 15 fits against the inner contour of the corresponding support component 8.

[0039] like Figure 2 and Figure 3 As shown, the drive structure includes a horizontal slide rail 3, a support base 5, a horizontal slide rail 2 51, a longitudinal slide rail 52, and a vertical slide rail 53. The horizontal slide rail 3 is fixedly installed on the top of the protective cover 2 by bolts. The industrial camera 4 is slidably mounted on the horizontal slide rail 3. The support base 5 is fixedly installed on the front and rear sides of the top of the base frame 1 by bolts. The top of each support base 5 is fixedly installed with a horizontal slide rail 2 51 by bolts. The longitudinal slide rail 52 is slidably installed between the two horizontal slide rails 2 51. The vertical slide rail 53 is slidably installed on the longitudinal slide rail 52. The laser chamfering machine 6 is fixedly installed on the bottom of the slider of the vertical slide rail 53. The horizontal slide rail 3, the horizontal slide rail 2 51, the longitudinal slide rail 52, and the vertical slide rail 53 are all electric slide rails, and the horizontal slide rail 3, the horizontal slide rail 2 51, the longitudinal slide rail 52, and the vertical slide rail 53 are all electrically connected to the controller 101.

[0040] like Figure 2 and Figure 3 As shown, it also includes a transmission gear 18 and a rack 19. The front end of each bidirectional lead screw 14 is fixedly connected to the transmission gear 18, and the front end of the top of the base frame 1 is fixedly installed with the rack 19. Each transmission gear 18 meshes with the rack 19.

[0041] like Figure 4 and Figure 5 As shown, it also includes a connecting seat 20, a drive motor 21, a drive gear 22, and a rack 23. The connecting seat 20 is fixedly installed on the top of each of the two feet 7. The drive motor 21 is fixedly installed on each of the two connecting seats 20 by bolts. The two drive motors 21 are electrically connected to the controller 101. The drive gear 22 is fixedly installed on the output shaft of each of the two drive motors 21. The rack 23 is fixedly installed on the front and rear sides of the top of the base frame 1. The two drive gears 22 mesh with the corresponding rack 23.

[0042] like Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a stop block 24, a return spring 25, and a filter screen 26. Each support member 8 has multiple discharge holes 10 on both the front and rear sides. Each support member 8 has a stop block 24 slidably arranged on both the front and rear sides. Each stop block 24 covers the discharge hole 10 on the corresponding side. Each stop block 24 is fixedly connected to the corresponding support member 8 with a return spring 25. Filter screens 26 are fixedly installed on the side of two stop blocks 24 on the same support member 8 that are close to each other.

[0043] like Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes a servo motor 17, a full gear 28, and an idler gear 29. The servo motor 17 is fixedly installed at the rear of the rear foot 7. The servo motor 17 is electrically connected to the controller 101. The output shaft of the servo motor 17 is fixedly connected to the rear end of the rightmost support member 8. A full gear 28 is fixedly installed at the rear of each support member 8. Multiple idler gears 29 are rotatably installed on the rear of the rear foot 7. Each full gear 28 and each idler gear 29 are alternately spaced, and each full gear 28 and each idler gear 29 mesh with each other.

[0044] like Figure 8 As shown, it also includes a striking block 27. Each bidirectional lead screw 14 is connected to a striking block 27 in the middle by an elastic element, which is an elastic pull rope.

[0045] like Figure 11 , Figure 12 , Figure 14 , Figure 15 , Figure 16 and Figure 17As shown, it also includes a discharge box 30, guide rods 31, return springs 32, and collection boxes 35. Multiple guide rods 31 are slidably installed on both the front and rear sides of the right side of the top of the base frame 1. A discharge box 30 is slidably arranged between each guide rod 31 on the same side. The bottom of the discharge box 30 is set to be high in the middle and low on both sides to facilitate the waste to slide to the outlets on both sides. Return springs 32 are fixedly installed between the two discharge boxes 30 and the guide rods 31. Multiple collection boxes 35 are placed on the top of the base frame 1. The collection boxes 35 are all located directly below the outlet of the discharge box 30.

[0046] like Figure 1 and Figure 17 As shown, it also includes pulleys 33 and collection frames 34. The tops of the two unloading boxes 30 are rotatably connected to multiple pulleys 33. When the carrier 8 tilts and flips, the carrier 8 squeezes the pulleys 33, causing the pulleys 33 to drive the unloading boxes 30 to move down. Two collection frames 34 for collecting waste are placed on the top right side of the base frame 1.

[0047] Initially, the feet 7 and the carrier 8 are both located on the top right side of the base frame 1. When the device is needed to perform laser chamfering on the sheet metal, the operator first places the sheet metal to be processed stably on top of the multiple carriers 8, ensuring that the sheet metal covers the multiple suction holes 9 opened on the surface of the carriers 8. Then, each suction connector 13 is connected to the external air extraction equipment through the hollow pipe. After the air extraction equipment is started, the negative pressure is transmitted through the suction connector 13 and the fixing seat 12 to the inner cavity of the hollow carrier 8, and the sheet metal is firmly adsorbed and fixed on the carrier 8 from the suction holes 9.

[0048] After the plate is fixed by adsorption, the operator starts the laser chamfering process through the controller 101. The controller 101 first controls the drive motor 21 fixed on the connecting seat 20 to start running in the forward direction. The output shaft of the drive motor 21 drives the drive gear 22 to rotate. The drive gear 22 meshes with the rack 23 fixed on the base frame 1, driving the two feet 7 to slide synchronously to the left along the base frame 1, smoothly sending the carrier 8 and the plate adsorbed on it into the protective cover 2. The protective cover 2 provides a closed environment for the entire processing. During the process of the feet 7 sliding to the left, the transmission gear 18 fixed at the front end of each bidirectional lead screw 14 rolls along the rack 19 fixed at the top of the base frame 1, forcing the bidirectional lead screw 14 to rotate in the forward direction. At this time, the two scrapers 15 threaded on the bidirectional lead screw 14 converge synchronously from both ends inside the carrier 8 to the middle. The edge of the scraper 15 always fits the inner contour of the carrier 8. This action is only to reserve the movement stroke for subsequent waste cleaning and does not affect the adsorption of the plate by the suction hole 9.

[0049] After the foot 7 drives the carrier 8 to fully enter the predetermined position inside the protective cover 2, the controller 101, according to the preset program, first controls the horizontal slide rail 3 to drive the industrial camera 4 to move horizontally, and records the outline, position and size of the board. The collected image information is transmitted back to the controller 101 in real time for analysis and processing. The controller 101 automatically plans the processing path of the laser chamfering machine 6 accordingly. Subsequently, the controller 101 synchronously controls the two electric slide rails, the horizontal slide rail 51 and the vertical slide rail 52, to work together: the horizontal slide rail 51 drives the vertical slide rail 52 to move horizontally as a whole, and the vertical slide rail 52 drives the vertical slide rail 53 to move vertically. At the same time, the vertical slide rail 53 drives the laser chamfering machine 6 to reach the specified height, realizing the three-axis linkage of the laser chamfering machine 6 fixed at the bottom of the vertical slide rail 53, and performing precise laser chamfering processing on the edge of the board according to the planned path. During this processing stage, some of the generated debris and waste will be scattered on the upper surface of the carrier 8 and around the air intake 9.

[0050] After all chamfering operations are completed, the controller 101 immediately controls the drive motor 21 to start running in reverse. The drive motor 21 reverses and, through the meshing of the drive gear 22 and rack 23, drives the foot 7 to slide to the right along the base frame 1, completely removing the carrier 8 and the processed sheet material from the protective cover 2. During this removal process, the transmission gear 18 rolls in reverse along the rack 19, driving the double-sided lead screw 14 to rotate in reverse. The two scraper frames 15, which were originally gathered in the middle, begin to move synchronously to the front and rear ends of the carrier 8, scraping the waste that has fallen into the carrier 8 to the front and rear ends of the carrier 8. Meanwhile, under the action of centrifugal force, the striking block 27 in the middle of each bidirectional lead screw 14 repeatedly swings and strikes the inner wall of the carrier 8 through the pull rope, shaking off the debris attached to the inner wall. When the scraper 15 moves to the front and rear ends of the carrier 8, it will push the block 24 covering the discharge hole 10. The block 24 compresses the reset spring 25 and slides, so that the discharge hole 10 is fully open. At this time, the waste accumulated in the inner cavity of the carrier 8 is smoothly discharged from the discharge hole 10 into the unloading box 30 under the action of gravity. During this process, the filter screen 26 continuously intercepts the waste to prevent the waste from being sucked into the suction equipment.

[0051] After the foot 7 is fully retracted, the controller 101 stops the suction device, and the suction port 9 releases its suction force on the board. The operator can then remove the chamfered board. Next, the controller 101 starts the servo motor 17, whose output shaft directly drives the rightmost support member 8 to rotate. The full gear 28 at the rear of this support member 8 is driven by an idler gear 29 that meshes with it, causing all support members 8 to rotate and tilt synchronously in the same direction. The tilting of the support members 8 causes debris to fall from their surface. Under the influence of gravity, the waste falls into the collection box 34. At the same time, the pulley 33 on the top of the unloading box 30 rolls into contact with the rotating support member 8. The support member 8 presses the unloading box 30 to move downward on the guide rod 31. At this time, the return spring 32 is compressed. After the waste is dumped, the controller 101 controls the servo motor 17 to reverse, so that the support member 8 rotates back to the horizontal state. The unloading box 30 will also shake and move upward under the reset action of the return spring 32, improving the efficiency of waste sliding off the unloading box 30, so as to avoid the accumulation of debris inside the unloading box 30.

[0052] As the entire process ends, the scraper 15 remains at the front and rear ends of the carrier 8, holding the stop 24 in place. The discharge hole 10 is still open. To allow the stop 24 to reset, the controller 101 controls the drive motor 21 to run forward briefly. The foot 7 then moves slightly to the left, and the transmission gear 18 rolls forward along the rack 19, driving the bidirectional lead screw 14 to rotate forward. This drives the two scrapers 15 to move from both ends toward the middle, disengaging from the stop 24. The stop 24 automatically slides under the elastic force of the return spring 25, completely closing the discharge hole 10 again. The filter screen 26 returns to its position with the stop 24. At this point, the controller 101 stops all electrical components from working, and the entire device returns to its initial standby state, ready for the next processing cycle.

[0053] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
