Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, in particular to a laser cutting device for cabinet processing. Background Art

[0002] In the field of cabinet processing, laser cutting devices use high-precision laser beams to achieve automated cutting of sheet materials, making them key equipment for improving cabinet production efficiency and processing accuracy. The laser cutting device for cabinet processing provided by the present invention, through the coordinated action of an adjustable lower and upper fixed frame, combined with the multi-dimensional movement of a laser cutting machine, can achieve automatic clamping and precise cutting of sheet materials of different sizes. Its core lies in the motor-driven retractable fixing mechanism, which adapts to sheet materials of various sizes while ensuring stability during the cutting process, which is of great significance to promoting the intelligent and efficient processing of cabinets.

[0003] Traditional cabinet laser cutting equipment has significant shortcomings. In terms of fixing mechanisms, traditional devices mostly use fixed-size fixtures, which need to be replaced frequently to adapt to different plates, resulting in interruptions in the production process, low efficiency, and an inability to meet diverse processing needs. The fixing accuracy is insufficient, and the plates are easily displaced during the cutting process due to loose clamping, resulting in hole deviation or distortion of the cutting contour, affecting the accuracy of cabinet assembly. The degree of automation is low, and manual adjustment of the fixture and plate positioning is time-consuming and labor-intensive, and there is a lack of dynamic anti-vibration mechanism. The vibration of the equipment during cutting can easily cause the plate to move slightly, further reducing accuracy. In addition, traditional equipment has a single way of fixing the edge of the plate, and cannot simultaneously achieve extrusion fixation of the upper and lower surfaces. It is difficult to cope with complex cutting requirements, which restricts the quality and efficiency improvement of cabinet processing. Summary of the Invention

[0011] According to one embodiment of the present invention, a sleeve rod is fixedly connected to the side surface of the upper combination rod of the lower fixing frame, and an upper fixing frame is slidably sleeved on the sleeve rod.

[0012] According to one embodiment of the present invention, the upper surfaces of the two side edges of the base plate are symmetrically penetrated and rotatably connected with rotating rods, the top of the rotating rod is set to be threaded, and the top of the rotating rod is connected to a ring through a thread, wherein the middle outer surface of the plug-in rod of the upper fixed frame is fixedly plugged with a sliding ring, the outer surface of the ring is slidably connected to the inner surface of the sliding ring, the top of the driving rod is rotatably sleeved with a No. 2 magnetic ring, the outer surface of the No. 2 magnetic ring is rotatably connected to a transmission belt, and the end of the transmission belt away from the No. 2 magnetic ring is rotatably connected to the bottom outer surface of the transfer rod.

[0013] According to one embodiment of the present invention, the interior of the extrusion frame is set to be hollow, and a positioning frame is slidably inserted into the bottom of the extrusion frame. The bottom surface of the positioning frame is made of rubber material, and a connecting port is provided on the top of the extrusion frame. The outer surface of the limit block is fixedly connected to an extrusion bag, and the end of the extrusion bag away from the limit block is fixedly connected to the end of the limit rod away from the limit block. The internal cavity of the extrusion frame is connected to the internal cavity of the extrusion bag through the connecting port on its top using a hose. The raw material square plate of the cabinet is placed under the cutting mechanism, and then the laser cutting machine is driven to move along the set X-axis and Y-axis to cut the plate. When the plate is placed Start the motor in this stage. After the motor is started, the transfer rod will be driven to rotate through the magnetic attraction of the drive shaft and the No. 1 magnetic ring. When the transfer rod starts to rotate, the movable disk starts to move up along the fixed rod under the action of the thread, and the tension on the pull rope on the movable disk gradually decreases. At this time, the elastic telescopic rod stretches outward and resets under the action of the elastic force, and starts to push the plug-in frame on the lower fixed frame to move outward, so that the combination rod is synchronously expanded outward through the cooperation of the plug-in rod and the combination rod, thereby realizing the overall expansion of the lower fixed frame. After the lower fixed frame is expanded to the specified distance, the cabinet panel to be cut is placed horizontally inside the lower fixed frame, and the motor is started in the reverse direction after the placement is completed.

[0014] The beneficial effects of the embodiments of the present invention are: (1) The laser cutting device for cabinet processing drives the movable plate downward by the reverse rotation of the motor, that is, the lower fixing frame begins to shrink by pulling the rope, and finally the plate is embedded in the lower fixing frame by shrinking the lower fixing frame, and the bottom surface of the plate is placed on the upper surface of the placement plate, so that the plate is automatically fixed when cutting. Moreover, the automatically adjustable lower fixing frame enables the device to adapt to the cutting and fixing of plates of multiple sizes, greatly improving the practicality of the device and avoiding the problem of low production efficiency caused by the need to frequently replace the fixture.

[0015] (2) The laser cutting device for cabinet processing, when the motor drives the driving shaft to rotate, the transmission belt on the second magnetic ring on the outer surface of the driving shaft will drive the rotating rod on the bottom plate to rotate, and the top of the rotating rod is connected to a collar by a thread, and the collar is limited by the sliding ring for lateral movement, that is, as the rotating rod rotates, the collar drives the sliding ring to start moving down along the rotating rod, and then the upper fixing frame fixedly connected to the sliding ring moves down along the collar, that is, finally the bottom surface of the upper fixing frame contacts the upper surface of the lower fixing frame, and the edge of the plate is squeezed and fixed by the extrusion frame on the upper fixing frame, and the upper fixing frame and the lower fixing frame are connected. The fixing frames are arranged in the same shape, and the upper fixing frame and the lower fixing frame are connected by a sleeve rod, so that the upper fixing frame and the lower fixing frame can be expanded and contracted synchronously, that is, the upper fixing frame can be contracted synchronously when the lower fixing frame is contracted and fixed to the plate, and can automatically move downward synchronously when contracting, and the upper surface of the edge of the plate can be squeezed and fixed by the extrusion frame, so that after the lower fixing frame clamps and fixes the plate, the extrusion frame and the placement plate can squeeze and cooperate with each other to synchronously squeeze and fix the edge of the plate, thereby greatly improving the fixing effect of the plate, and avoiding the problem of lateral movement of the plate when cutting the hole, resulting in substandard cutting requirements.

[0016] (3) In the laser cutting device for cabinet processing, the driving rod is connected to the transfer rod by magnetic rotation through the No. 1 magnetic ring, that is, initially, the rotation of the driving rod will drive the transfer rod to rotate synchronously through the No. 1 magnetic ring, and begin to cause the lower fixing frame to shrink to fix the plate. When the plate size is large, the shrinkage distance of the lower fixing frame is greatly reduced, that is, after the plate is fixed by the lower fixing frame, the driving shaft continues to rotate due to the action of the motor. At this time, the transfer rod cannot continue to rotate due to the action of the lower fixing frame, that is, the driving rod continues to rotate relative to the stationary transfer rod under the action of the No. 1 magnetic ring, and the outer surface of the driving rod drives the rotating rod to continue to rotate through the transmission belt on the No. 2 magnetic ring, so that the upper fixing frame can move downward normally, thereby ensuring that when the plate size is large, the setting of the No. 1 magnetic ring allows the upper fixing frame to continue to move downward automatically without being affected to squeeze and fix the plate. On the contrary, when the plate size is small, the upper fixing frame will first drop to the bottom and contact the upper surface of the plate. At this time, as the lower fixing frame continues to shrink, the upper fixing frame cannot continue to move downward, that is, the driving rod and the No. 2 magnetic ring undergo relative rotation, so that When the upper fixing frame is extruded and fitted with the plate, the contraction effect of the lower fixing frame is not affected, and the fixing of plates of multiple sizes is completed, which greatly improves the automation level of the device. After the processing is completed, the reverse motor can drive the lower fixing frame to start expanding, and the upper fixing frame can move upward during the synchronous expansion, losing the fixation of the plate, thereby greatly reducing the difficulty of disassembling and assembling the plate and improving production efficiency. When the extrusion frame contacts and extrudes the edge of the plate, the positioning frame at the bottom of the extrusion frame will first contact the upper surface of the edge of the plate. At this time, as the upper fixing frame continues to move downward, the positioning frame will move toward the inside of the extrusion frame, that is, the internal cavity pressure of the extrusion frame is increased, and finally the internal air pressure is transmitted to the extrusion bag through the hose, so that the internal air pressure of the extrusion bag is increased, and the expansion of the extrusion bag generates an inward extrusion force on the diagonal of the lower fixing frame, thereby ensuring that the lower fixing frame is reversely extruded and fixed during the cutting process, avoiding the problem that the lower fixing frame vibrates as the device works during the cutting process, resulting in slight expansion and contraction, causing slight movement of the plate and reducing the cutting accuracy.

[0032] A sleeve rod 421 is fixedly connected to the side surface of the upper combination rod 42 of the lower fixing frame 41, and an upper fixing frame 422 is slidably sleeved on the sleeve rod 421. The upper fixing frame 422 and the lower fixing frame 41 are arranged in the same shape, wherein the bottom inner surface of the combination rod 42 of the upper fixing frame 422 is fixedly connected to an extrusion frame 423, and the bottom of the extrusion frame 423 is protruding from the bottom surface of the upper fixing frame 422, and the extrusion frame 423 is arranged in an L-shape.

[0033] The upper surfaces of the two side edges of the base plate 1 are symmetrically penetrated and rotatably connected with a rotating rod 424, the top of the rotating rod 424 is set to be threaded, and the top of the rotating rod 424 is connected to a ring 425 through a thread, wherein the middle outer surface of the plug-in rod 44 of the upper fixed frame 422 is fixedly plugged with a sliding ring 426, and the outer surface of the ring 425 is slidably connected to the inner surface of the sliding ring 426, and the top of the driving rod 414 is rotatably sleeved with a No. 2 magnetic ring 427, and the outer surface of the No. 2 magnetic ring 427 is rotatably connected to a transmission belt 428, and the end of the transmission belt 428 away from the No. 2 magnetic ring 427 is rotatably connected to the bottom outer surface of the transfer rod 411.

The internal cavity of the extrusion frame 423 is connected to the internal cavity of the extrusion capsule 430 through the connecting port on its top using a hose.

[0035] During operation, the raw material square plate of the cabinet is placed under the cutting mechanism 3, and then the laser cutting machine 33 is driven to move along the set X-axis and Y-axis to cut the plate. During the plate placement stage, the motor 416 is started. After the motor 416 is started, the transfer rod 411 is driven to rotate through the magnetic attraction of the drive shaft and the No. 1 magnetic ring 413. When the transfer rod 411 starts to rotate, the movable plate 418 starts to move up along the fixed rod 417 under the action of the thread, and the tension of the pull rope 420 on the movable plate 418 is gradually reduced. At this time, the elastic telescopic rod 47 stretches outward and resets under the action of the elastic force, that is, it starts to push the plug-in frame on the lower fixed frame 41 to move outward, so that the plug-in rod 44 and the combination rod 42 cooperate with each other to make The combination rod 42 is synchronously extended outward to realize the overall expansion of the lower fixing frame 41. After the lower fixing frame 41 is expanded to the specified distance, the cabinet plate to be cut is placed horizontally inside the lower fixing frame 41, and the motor 416 is started in reverse after the placement is completed. The movable plate 418 is driven downward by the reverse rotation of the motor 416, that is, the lower fixing frame 41 begins to shrink through the pull rope 420, and finally the plate is embedded in the lower fixing frame 41 through the shrinkage of the lower fixing frame 41, and the bottom surface of the plate is placed on the upper surface of the placement plate 43, so that the plate is automatically fixed when cutting. The automatically adjustable lower fixing frame 41 can adapt the device to the cutting and fixing of plates of multiple sizes, greatly improving the practicality of the device and avoiding the need The problem of low production efficiency caused by frequent replacement of fixtures, when the motor 416 drives the driving shaft to rotate, the transmission belt 428 on the second magnetic ring 427 on the outer surface of the driving shaft will drive the rotating rod 424 on the bottom plate 1 to rotate, and the top of the rotating rod 424 is connected to the ring 425 by a thread, and the ring 425 is limited by the sliding ring 426 for lateral movement, that is, as the rotating rod 424 rotates, the ring 425 will drive the sliding ring 426 to start moving down along the rotating rod 424, and then the upper fixing frame 422 fixedly connected to the sliding ring 426 will move down along the sleeve rod 421, that is, finally the bottom surface of the upper fixing frame 422 contacts the upper surface of the lower fixing frame 41, and the edge of the plate is squeezed by the extrusion frame 423 on the upper fixing frame 422. The upper fixing frame 422 and the lower fixing frame 41 are squeezed and fixed, and the upper fixing frame 422 and the lower fixing frame 41 are set in the same shape, and the upper fixing frame 422 and the lower fixing frame 41 are connected by the sleeve rod 421, that is, the upper fixing frame 422 and the lower fixing frame 41 are synchronously expanded and contracted. When the lower fixing frame 41 is contracted and fixed, the upper fixing frame 422 is synchronously contracted, and automatically moves downward when contracting, and the upper surface of the edge of the plate is squeezed and fixed by the squeezing frame 423, so that after the lower fixing frame 41 clamps and fixes the plate, the squeezing frame 423 and the placing plate 43 squeeze and cooperate with each other to synchronously squeeze and fix the edge of the plate, thereby greatly improving the fixing effect of the plate, avoiding the problem of lateral movement of the plate when cutting the hole, resulting in substandard cutting requirements.The driving rod 414 is magnetically connected to the transfer rod 411 through the first magnetic ring 413. That is, initially, the rotation of the driving rod 414 will drive the transfer rod 411 to rotate synchronously through the first magnetic ring 413, and begin to cause the lower fixing frame 41 to contract to fix the plate. When the plate size is large, the contraction distance of the lower fixing frame 41 is greatly reduced. That is, when the plate is fixed by the lower fixing frame 41, the driving shaft continues to rotate due to the action of the motor 416. At this time, the transfer rod 411 cannot continue to rotate due to the action of the lower fixing frame 41. That is, the driving rod 414 continues to rotate relative to the stationary transfer rod 411 under the action of the first magnetic ring 413. The outer surface of the driving rod 414 drives the rotating rod 424 to continue to rotate through the transmission belt 428 on the second magnetic ring 427, so that the upper fixing frame 422 can move down normally, thereby ensuring that when the size of the plate is large, the setting of the first magnetic ring 413 ensures that the upper fixing frame 422 can still be automatically moved down to squeeze and fix the plate. On the contrary, when the size of the plate is small, the upper fixing frame 422 will first drop to the bottom and contact the upper surface of the plate. At this time, as the lower fixing frame 41 continues to shrink, the upper fixing frame 422 cannot continue to move down, that is, the driving rod 414 and the second magnetic ring 427 rotate relative to each other. The automatic movement makes it possible for the upper fixing frame 422 to press and fit the plate without affecting the contraction of the lower fixing frame 41, thereby completing the fixation of plates of multiple sizes and greatly improving the degree of automation of the device. After the processing is completed, the reverse motor 416 can drive the lower fixing frame 41 to start expanding, and make the upper fixing frame 422 move upward during the synchronous expansion, losing the fixation of the plate, thereby greatly reducing the difficulty of disassembling and assembling the plate and improving production efficiency. When the extrusion frame 423 contacts and extrudes the edge of the plate, the positioning frame 429 at the bottom of the extrusion frame 423 will first contact the upper surface of the edge of the plate. At this time, as the upper fixing frame 416 is pressed, the lower fixing frame 41 will be pressed and the upper fixing frame 42 ... The continued downward movement of the fixed frame 422 causes the positioning frame 429 to move into the extrusion frame 423, increasing the pressure in the internal cavity of the extrusion frame 423. This pressure is eventually transferred to the extrusion bag 430 through the hose, increasing the internal pressure of the extrusion bag 430. The expansion of the extrusion bag 430 generates an inward extrusion force on the opposite corner of the lower fixed frame 41, thereby ensuring that the lower fixed frame 41 is reversely extruded and fixed during the cutting process, avoiding the problem of the lower fixed frame 41 vibrating during the cutting process, causing slight expansion and contraction, resulting in slight movement of the sheet metal and reducing cutting accuracy.
