Description

Technical Field

[0001] The invention belongs to the technical field of laser processing, and in particular relates to a storage box plate laser cutting machine. Background Art

[0002] Laser cutting of storage box sheets is a high-precision and high-efficiency processing method, especially suitable for making storage boxes made of transparent or translucent materials such as acrylic. Laser cutting can be used for cutting. Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and vaporized to form holes. As the beam moves toward the material, the holes continue to form narrow slits, thereby completing the cutting of the material. The precision of laser cutting is very high, and it can achieve millimeter-level or even finer cutting, ensuring the size and shape of the storage box are accurate.

[0003] For example, a Chinese patent with announcement number CN217513100U discloses a laser cutting machine. When a steel plate to be cut is placed on a placement plate, the cylinders located at both ends of the placement plate in the length direction first push the baffles to respectively abut against the two ends of the length direction of the steel plate to be cut, thereby making the center line of the length direction of the steel plate to be cut coincide with the center line of the length direction of the placement plate, and then the cylinders located at both ends of the length direction of the placement plate retract, and then the cylinders located on both sides of the length direction of the placement plate drive the baffles to push the steel plate to be cut, so that the center line of the width direction of the steel plate to be cut coincides with the center line of the placement plate. The center lines in the width direction coincide with each other. At this time, the intersection of the two center lines of the workpiece coincides with the intersection of the two center lines of the plate placed on the machine tool body. Therefore, the staff can use the intersection of the two center lines of the plate placed on the machine tool body as the reference point to cut the steel plate to be cut. However, if the specification size of the previous workpiece to be cut is too different from the specification size of the next workpiece to be cut, or the position on the laser cutting machine is different, this will require the staff to spend time to adjust the position of the next workpiece to be cut after the previous workpiece is cut, which is inefficient.

[0004] For example, a Chinese patent with announcement number CN218050879U discloses a laser cutting machine, in which the device is installed on a mobile mechanism through a mounting rod. When the laser transmitter is cutting the material, the suction pump is started, and the exhaust gas and dust generated during the cutting are sucked in through the suction hose, and then discharged from the exhaust pipe into the dust chamber after passing through the hollow plate and the suction pipe. The wind force is downward due to the obstruction of the baffle, preventing the wind force from directly aiming at the filter screen and causing some dust to penetrate. The dust stays in the dust chamber, and the exhaust gas passes through the filter screen and is purified and discharged through the activated carbon in the filter chamber, thereby reducing the pollution of dust and exhaust gas. However, the heat dissipation effect of the device is poor during cutting, resulting in debris easily accumulating at the cutting point during the cutting process, resulting in an uneven cutting point.

The threaded sleeve is connected to the outer side of the limit component 8, and the placement component 7 is fixedly connected to the middle of the cutting table 1; the cutting table 1 is used to support the limit component 8 and the placement component 7, the placement component 7 is used to place the storage box plate, the linear motor 2 is used to drive the connecting frame 3 and the multi-angle cutting frame 4, the multi-angle cutting frame 4 is used to connect and rotate the laser cutter 5, the laser cutter 5 is used to cut the storage box plate, the rotary clamping component 6 is used to clamp and rotate the storage box plate of different thicknesses, and the limit component 8 is used to drive the rotary clamping component 6 and displace synchronously.

[0025] The device adds a multi-angle cutting frame 4 to cooperate with the laser cutter 5 to accurately find the angle of laser cutting. The linear motor 2 is used to stabilize the laser cutting station by moving the connecting frame 3 and the multi-angle cutting frame 4 installed on the surface of the mover, so as to achieve a fully automated cutting effect. The control end starts the top propulsion cylinder 433, and its piston end pushes the push rod 434, so that the telescopic arm 432 can extend the large sleeve column 431 to complete the length extension. At the same time, the stepper motor 442 on the bracket 441 is started, so that the positioning column 443 can drive the outer clamping arm body to complete the angle fine-tuning, and then accurately find the storage box plate and clamp it. In addition, the device adds two sets of relatively opened clamping seats 64 and asynchronous motors 671 above the sliding table 84, so that the device can clamp storage box plates of different sizes, and achieve rapid cutting and rapid flipping of thicker storage box plates, thereby improving the scope of application of the device.

[0026] like Figure 3-Figure 8 As shown, the rotary clamping assembly 6 includes a driving motor 61, a transmission shaft 62, a connecting arm 63, a clamping seat 64, an articulated sleeve 65, a fixed frame 66 and a rotating portion 67. The driving motor 61 is threadedly connected to one side of the fixed frame 66, the transmission shaft 62 is symmetrically arranged on the inner side of the fixed frame 66, and the inner side of the transmission shaft 62 is fixedly connected to the motor shaft of the driving motor 61 through a coupling, the top outer side of the connecting arm 63 is fixedly connected to the surface of the transmission shaft 62, the bottom of the clamping seat 64 is fixedly connected to the bottom surface of the connecting arm 63, the middle part of the articulated sleeve 65 is hinged to one side of the clamping seat 64, and the rotating portion 67 is fixedly connected to the middle outer side of the fixed frame 66.

[0027] The storage box plate is placed on the support plate 74, and then the hydraulic cylinder 72 above the support plate 71 is started, and the upper support plate 74 is pushed through the two sets of lifting rods 73, so that the storage box plate placed above is lifted to the clamping position of the clamping base 64, and then the DC motor 81 outside the cutting table 1 is started, and its motor shaft drives the bidirectional screw 82 to rotate. Since the linear shaft 83 is fixed on both sides of the cutting table 1, the rotation of the sliding table 84 is hindered; and since the thread surface of the bidirectional screw 82 is adapted to the thread groove 10 of the sliding table 84, under the drive of the screw, the two sets of sliding tables 84 can move relative to or opposite to each other along the opening direction of the through hole 11, thereby adjusting the distance between the two sets of sliding tables 84 to adapt to storage box plates of different sizes, thereby facilitating subsequent flipping and clamping.

[0028] The multi-angle cutting frame 4 includes a first support arm 41, a rotating joint 42, a swing arm 43 and an adjusting arm 44. The first support arm 41 is fixedly connected to the top of the connecting frame 3, the rotating joint 42 is rotatably connected to the top of the first support arm 41, the inner side of the swing arm 43 is fixedly connected to the middle part of the rotating joint 42, and the adjusting arm 44 is fixedly connected to the outer side of the swing arm 43.

[0029] Start the driving motor 61 on one side of the fixed frame 66, and the driving motor 61 drives the transmission shaft 62 to rotate, so that the transmission shaft 62 drives the connecting arm 63 to rotate along the outer side of the fixed frame 66, and the bottom of the connecting arm 63 pulls the clamping seat 64 slightly, so that the clamping seat 64 can move in a semicircle along the hinge of the hinge sleeve 65. Since the transmission gear 9 of the upper transmission shaft 62 is meshed with the transmission gear 9 at the lower end, under the condition of gear transmission, the upper and lower groups of connecting arms 63 drive the two groups of clamping seats 64 to complete synchronous relative movement, so as to flexibly flip and clamp the storage box plate, which is convenient for quick cutting of thicker storage box plates.

[0030] The placement assembly 7 includes a support plate 71, a hydraulic cylinder 72, a lifting rod 73 and a support plate 74. The support plate 71 is fixedly connected to the middle of the cutting table 1, the output end of the hydraulic cylinder 72 is fixedly connected to one end of the lifting rod 73, the lifting rod 73 is fixedly connected to the bottom of the support plate 74, and the top of the support plate 74 is in conflict with the surface of the storage box plate.

[0031] The limit assembly 8 includes a DC motor 81, a bidirectional screw 82, a linear shaft 83 and a sliding table 84. The DC motor 81 is installed on the outside of the cutting table 1. One end of the bidirectional screw 82 is fixedly connected to the motor shaft of the DC motor 81 through a coupling. The linear shaft 83 is fixedly connected to the inner side of the cutting table 1. The sliding table 84 is threadedly sleeved on the outside of the bidirectional screw 82.

[0032] The rotating part 67 includes an asynchronous motor 671 and a rotating shaft 672. The asynchronous motor 671 is installed on the top outer side of the sliding table 84. The rotating shaft 672 is fixedly connected to the outer side of the output end of the asynchronous motor 671. The rotating shaft 672 passes through the top inner wall of the sliding table 84 and is fixedly connected to the middle of the fixed frame 66.

[0033] The interior of the fixed frame 66 is also provided with mutually meshing transmission gears 9 , and the transmission gears 9 are sleeved on the outer side of the transmission shaft 62 .

[0034] The adjusting arm 44 includes a bracket 441, a stepper motor 442 and a positioning column 443. The bracket 441 is fixedly connected to the outside of the swing arm 43. The stepper motor 442 is installed on the outside of the bracket 441 and fixedly connected to one end of the positioning column 443. The outside of the positioning column 443 is fixedly connected to the top of the laser cutter 5.

[0035] The swing arm 43 includes a large sleeve column 431, a telescopic arm 432, a thrust cylinder 433 and a push rod 434. The large sleeve column 431 is sleeved on one side of the telescopic arm 432, the piston end of the thrust cylinder 433 is fixedly connected to one end of the push rod 434, and the outer side of the push rod 434 is fixedly connected to the top surface of the telescopic arm 432.

[0036] During the cutting process, the linear motor 2 can be started, and the moving end of the linear motor 2 pushes the connecting frame 3, and the connecting frame 3 pushes the first supporting arm 41 above to move stably along the X-axis direction. The rotating joint 42 needs to rely on the hydraulic driver to realize its bending movement, thereby driving the swing arm 43 and the adjusting arm 44 to bend. At the same time, the control end starts the top propulsion cylinder 433, and its piston end pushes the push rod 434, so that the telescopic arm 432 can extend the large sleeve column 431 to complete the length extension. At the same time, the stepper motor 442 on the bracket 441 is started, and the running stepper motor 442 drives the positioning column 443 to rotate, so that the positioning column 443 can drive the outer laser cutter 5 to complete the angle fine-tuning, thereby accurately finding the cutting position of the storage box plate and achieving stable cutting. The interior of the sliding table 84 is penetrated by a thread groove 10 and a through hole 11 that match the sizes of the bidirectional screw 82 and the linear shaft 83 .

[0037] Working principle: place the storage box plate on the support plate 74, then start the hydraulic cylinder 72 above the support plate 71, and push the upper support plate 74 through two sets of lifting rods 73, so as to lift the storage box plate placed above to the clamping position of the clamping base 64, and then start the DC motor 81 outside the cutting table 1, and its motor shaft drives the bidirectional screw 82 to rotate. Since the linear shaft 83 is fixed on both sides of the cutting table 1, the rotation of the sliding table 84 is hindered; and since the thread surface of the bidirectional screw 82 is adapted to the thread groove 10 of the sliding table 84, under the drive of the screw, the two sets of sliding tables 84 can move relative to or opposite to each other along the opening direction of the through hole 11, thereby adjusting the distance between the two sets of sliding tables 84 to adapt to storage box plates of different sizes, thereby facilitating subsequent flipping and clamping. During the clamping process, the driving motor 61 on one side of the fixed frame 66 can be started, and the driving motor 61 drives the transmission shaft 62 to rotate, so that the transmission shaft 62 drives the connecting arm 63 to rotate along the outer side of the fixed frame 66, and the bottom of the connecting arm 63 pulls the clamping seat 64 slightly, so that the clamping seat 64 can move in a semicircle along the hinge of the hinge sleeve 65. Since the transmission gear 9 of the upper transmission shaft 62 is meshed with the transmission gear 9 at the lower end, under the condition of gear transmission, the upper and lower groups of connecting arms 63 drive the two groups of clamping seats 64 to complete synchronous relative movement, so as to flexibly flip and clamp the storage box plate, which is convenient for quick cutting of thicker storage box plates. In addition, during the cutting process, the linear motor 2 can be started, and the movable end of the linear motor 2 pushes the connecting frame 3, and the connecting frame 3 pushes the first support arm 41 above to move stably along the X-axis direction. The rotating joint 42 needs to rely on the hydraulic drive to realize its bending movement, thereby driving the swing arm 43 and the adjustment arm 44 to bend. At the same time, the control end starts the thrust cylinder 433 at the top, and its piston end pushes the push rod 434, so that the telescopic arm 432 can extend the large sleeve column 431 to complete the length extension. At the same time, the stepper motor 442 on the bracket 441 is started, and the running stepper motor 442 drives the positioning column 443 to rotate, so that the positioning column 443 can drive the outer laser cutter 5 to complete the angle fine-tuning, thereby accurately finding the cutting position of the storage box plate and achieving stable cutting.
