[0002] The hardware parts used in furniture processing refer to various metal fittings used to connect, fix or decorate furniture components during the furniture manufacturing process. These hardware parts include, but are not limited to, hinges, screws, nails, handles, locks, tracks, etc. They are usually made of materials such as iron, stainless steel, copper or aluminum alloy to meet the different furniture design and functional requirements. In traditional processing methods, the processing of these hardware parts often requires multiple steps, including stamping, cutting, grinding, etc., which not only has low efficiency, but also makes it difficult to ensure accuracy and consistency. The laser cutting device and method provided by the present invention can effectively solve these problems and improve the accuracy and efficiency of hardware part processing.

[0003] According to the patent document: CN218874126U, a laser cutting device for hardware part processing disclosed includes a laser cutting device box body. Vertical guide rails are fixedly connected to the left and right side walls of the laser cutting device box body. A horizontal cross bar is slidably installed in the vertical guide rails. A laser cutting device is slidably installed at the lower end of the horizontal cross bar. Collection devices are symmetrically and fixedly installed at the lower left and right ends of the laser cutting device. A clamping plate device is snap-fitted to the upper end of the laser cutting device box body. A dust collection device is provided on the inner wall of the upper end of the laser cutting device. A purification box is fixedly installed inside the laser cutting device and is connected to the collection device. When the laser cutting device for hardware part processing operates, the blower starts to run, and the dust suction hood moves along with the laser cutting device. The generated waste materials and harmful gases will be sucked away by the dust suction hood and then enter the purification box along the dust suction air duct, which not only improves the work efficiency, but also protects the health of the operator.

[0027] 1. The present invention can effectively avoid the problem of reduced cutting accuracy caused by the movement or vibration of the metal fixing plate during the laser cutting process by providing a control mechanism, a control frame, and a transmission component. The entire cutting process has a high degree of automation and is easy to operate, which greatly improves the production efficiency and cutting accuracy of hardware for furniture processing. Specifically, when laser cutting a metal fixing plate, first activate the two-way hydraulic push rod to pull the push-pull block and the push-pull cross bar to move in the C-shaped slide groove, and then make the rotating rod and the L-shaped expansion rod slide, driving the thickness sensing clamp to clamp the metal fixing plate. This design prevents movement or vibration during the cutting process and ensures accuracy.

After the cutting is completed, the two-way hydraulic push rod resets the equipment to prepare for the next operation.

[0028] 2. The present invention is provided with a positioning mechanism, which can accurately position the metal fixing plate. The positioning plate chute rod of the positioning mechanism and the hydraulic push rod connecting rod work together to ensure that the metal fixing plate can be accurately fixed at a predetermined position before laser cutting. Specifically, when the metal fixing plate moves on the conveyor belt of the laser cutting device to the inside of the two hub plates, the hydraulic push rod starts, pushes the L-shaped rotating rod to rotate, drives the hub plates to move inward, and clamps the metal fixing plate. As the conveyor belt continues to convey, the metal fixing plate is stably conveyed and accurately positioned through the rotation of multiple hubs on the inner wall of the hub plates.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] As Figures 1-3 shown, the present invention provides a laser cutting device for furniture processing hardware, including a laser cutting device 1. The top of the inner wall of the laser cutting device 1 is fixedly connected with a total control frame 2. The bottom of the total control frame 2 is fixedly connected with a control mechanism 3. The rear sides of the left and right sides of the control mechanism 3 are respectively fixedly connected with a positioning mechanism 4;

[0042] When it is necessary to perform laser cutting on a metal fixing plate, the metal fixing plate is placed on the conveyor belt provided by the laser cutting device 1 for transmission to the inner wall of the laser cutting device 1. When the metal fixing plate enters the inner wall of the laser cutting device 1, the overall bottom of the laser cutting device 1 is controlled by the total control frame 2 to drop to a suitable position, and the position of the metal fixing plate on the conveyor belt is adjusted by the two positioning mechanisms 4 so that it can be aligned with the bottom of the control mechanism 3. After completely disengaging from the positioning mechanism 4, the metal fixing plate is positioned by the control mechanism 3 and cut.

[0043] As Figures 4-8As shown in the figure, the control mechanism 3 includes a control frame 31. A transmission component 32 is fixedly connected to the top of the control frame 31. The control frame 31 includes two side plates 311. Connecting blocks 313 are fixedly connected to the front and rear sides inside the two side plates 311.

Vertical rod chute block connecting blocks 314 are fixedly connected to the tops of the left and right groups of connecting blocks 313. Vertical rod chute blocks 315 are fixedly connected to the inside of the left and right groups of vertical rod chute block connecting blocks 314. Connecting blocks 316 are fixedly connected to the outside of the left and right groups of connecting blocks 313. The tops of the two groups of connecting blocks 316 are fixedly connected to the two sides of the bottom of the total control frame 2 respectively. The transmission component 32 includes a two-way push rod connecting plate 321. L-shaped side plates 322 are fixedly connected to the left and right sides of the top of the two-way push rod connecting plate 321 respectively. The outsides of the two L-shaped side plates 322 are fixedly connected to the inside of the two groups of vertical rod chute blocks 315 respectively. A two-way hydraulic push rod connecting block 323 is fixedly connected to the bottom of the two-way push rod connecting plate 321. A two-way hydraulic push rod 324 is fixedly connected to the inner wall of the two-way hydraulic push rod connecting block 323. C-shaped chute frames 325 are fixedly connected to the front and rear sides of the bottom of the two-way push rod connecting plate 321 respectively. Push-pull cross bars 326 are slidably connected to the inner walls of the two C-shaped chute frames 325. Hinge blocks 327 are fixedly connected to the middle parts of the outer walls of the two push-pull cross bars 326. Two rotating rods 328 with opposite directions are rotatably connected to the bottoms of the two groups of hinge blocks 327. Push rods 329 are fixedly connected to the inside of the two push-pull cross bars 326. The insides of the two push rods 329 extend to the outside of the C-shaped chute frames 325 through the inside of the two C-shaped chute frames 325 respectively and push-pull blocks 3210 are fixedly connected to the tops. The insides of the two push-pull blocks 3210 are fixedly connected to the front and rear ends of the two-way hydraulic push rod 324 respectively. L-shaped expansion and contraction rod chutes 3211 are respectively opened on the left and right sides outside the two C-shaped chute frames 325. L-shaped expansion and contraction rods 3212 are rotatably connected to the sides of the two groups of rotating rods 328 far away from the hinge blocks 327. The outer walls of the two groups of L-shaped expansion and contraction rods 3212 are respectively slidably connected to the inner walls of the two groups of L-shaped expansion and contraction rod chutes 3211. Thickness sensing clamping plates 3213 are fixedly connected to the bottoms of the two groups of L-shaped expansion and contraction rods 3212. The outer walls of the two groups of L-shaped expansion and contraction rods 3212 are slidably connected to the inside of the connecting blocks 316 and the connecting blocks 313. The bottoms of the two groups of L-shaped expansion and contraction rods 3212 extend to the outside bottoms of the side plates 311 and thickness sensing clamping plates 3213 are fixedly connected to both. Push-pull blocks 3210 are fixedly connected to the left and right sides where the outer walls of the two push rods 329 extend to the outside of the C-shaped chute frames 325. Rotating rods 3215 are rotatably connected to the sides of the bottoms of the two groups of push-pull blocks 3210 far away from the push rods 329. Laser cutter connecting plates 3216 are rotatably connected to the sides of the two groups of rotating rods 3215 far away from the rotating rod connecting rods 3214. A laser cutter 3218 is movably connected to the bottom of the laser cutter connecting plate 3216,On the four sides of the top of the laser cutting machine connecting plate 3216, connecting plate vertical rods 3217 are fixedly connected respectively. The outer walls of the left and right groups of connecting plate vertical rods 3217 are respectively slidably connected to the inner walls of the left and right groups of vertical rod chute blocks 315;

[0044] When laser cutting of the metal fixing plate is required, first start the two-way hydraulic push rod 324 at the bottom of the two-way push rod connecting plate 321. After the two-way hydraulic push rod 324 is started, it pulls two push-pull blocks 3210 to move inward. The movement of the two push-pull blocks 3210 drives the push-pull rod 329 to pull two push-pull cross bars 326 to slide inward on the inner wall of the C-shaped chute frame 325. While the two push-pull cross bars 326 slide inward, two groups of hinge blocks 327 pull two groups of rotating rods 328 with opposite directions to rotate. Then, through the two groups of rotating rods 328, the L-shaped expansion and contraction rod 3212 is pulled to slide inward between the connecting block 313 and the connecting block 316, thereby driving two groups of thickness sensing clamping plates 3213 to move inward to clamp and fix the metal fixing plate on the conveyor belt, and the thickness of the metal fixing plate is sensed by the inner sides of the two groups of thickness sensing clamping plates 3213. And through this design, the problem of the decrease in cutting accuracy caused by the movement or vibration of the metal fixing plate during the laser cutting process can be effectively avoided;

[0045] At the same time, when the two push-pull rods 329 move inward, two groups of rotating rod connecting rods 3214 drive two groups of rotating rods 3215 to rotate. The rotation of the two groups of rotating rods 3215 further pushes the laser cutting machine connecting plate 3216 to move downward and drives the laser cutting machine 3218 at its bottom to move downward and approach the surface of the metal fixing plate fixed by the two groups of thickness sensing clamping plates 3213. At this time, the metal fixing plate can be laser cut by the laser cutting machine 3218. After the laser head of the laser cutting machine 3218 is aligned with the predetermined cutting position of the metal fixing plate, the laser cutting machine 3218 starts to work, emits a laser beam to precisely cut the metal fixing plate. During the cutting process, the movement of the laser cutting machine 3218 is precisely controlled by the control mechanism 3 to ensure that the cutting path and depth meet the design requirements. After the cutting is completed, the two-way hydraulic push rod 324 works in the reverse direction to move the laser cutting machine 3218 and the thickness sensing clamping plate 3213 back to the initial position to prepare for the next cutting operation. The entire cutting process has a high degree of automation and is easy to operate, greatly improving the production efficiency and cutting accuracy of the hardware parts for furniture processing.

[0046] Such as Figures 9-10As shown in the figure, both of the two positioning mechanisms 4 include positioning plate chute rods 41. On the front sides of the two positioning plate chute rods 41, hydraulic push rod connecting rods 42 are fixedly connected respectively. The inner sides of the two hydraulic push rod connecting rods 42 are fixedly connected to the outer sides of the two connecting rods 312 respectively. The front sides of the two positioning plate chute rods 41 are fixedly connected to the rear sides of the two connecting rods 312 respectively. Inside walls of the two hydraulic push rod connecting rods 42 are fixedly connected with hydraulic push rods 43. On the outer sides of the two hydraulic push rod connecting rods 42, L-shaped rotating rod hinge blocks 44 are fixedly connected respectively. Inside walls of the two L-shaped rotating rod hinge blocks 44 are rotatably connected with L-shaped rotating rods 45. On the rear sides of the two L-shaped rotating rods 45, L-shaped rotating rod pushing blocks 46 are fixedly connected respectively. The inner sides of the two L-shaped rotating rod pushing blocks 46 are fixedly connected to the outer ends of the two hydraulic push rods 43 respectively. On the outer walls of the two L-shaped rotating rods 45 away from the L-shaped rotating rod pushing blocks 46, abutting plates 47 are rotatably connected respectively. Inside the two abutting plates 47, hub plates 48 are fixedly connected respectively. Inside walls of the two hub plates 48 are rotatably connected with a plurality of hubs 49. On the rear sides of the two hub plates 48, hub plate slide rods 410 are fixedly connected respectively. Outer walls of the two hub plate slide rods 410 are slidably connected to the rear inner walls of the positioning plate chute rods 41;

[0047] When the metal fixing plate is being transported on the conveyor belt of the laser cutting device 1, when the metal fixing plate moves to the inside of the two hub plates 48, at this time, start the two hydraulic push rods 43. After the two hydraulic push rods 43 are started, they push the L-shaped rotating rod pushing blocks 46 to drive the L-shaped rotating rods 45 to rotate. The two L-shaped rotating rods 45 rotate with the L-shaped rotating rod hinge blocks 44 as the axes, and then push the abutting plates 47 to drive the hub plates 48 to move inward. At this time, the metal fixing plate is clamped inside the two hub plates 48. When the conveyor belt of the laser cutting device 1 continues to transport, the metal fixing plate can move by rotating through the plurality of hubs 49 fixed to the inner walls of the hub plates 48, so as to realize the stable transportation and precise positioning of the metal fixing plate.

[0048] In addition, the present invention also relates to a cutting method for a laser cutting device of furniture processing hardware, including the following steps:

[0049] Step 1: Place the metal fixing plate on the conveyor belt, start the conveyor belt to move the metal fixing plate to the inner wall of the laser cutting device 1;

[0050] Step 2: Control the overall bottom of the laser cutting device 1 to drop to a suitable position through the main control frame 2 to ensure that the metal fixing plate can be aligned with the bottom of the control mechanism 3;

[0051] Step 3: With the assistance of the positioning mechanism 4, the metal fixing plate rotates through the hubs 49 on the hub plates 48 to realize stable transportation and precise positioning

[0052] Step 4: Position the metal fixing plate through the control mechanism 3, adjust its position, and make it completely disengage from the positioning mechanism 4;

[0053] Step 5: Start the bidirectional hydraulic push rod 324 in the control mechanism 3, so that the push-pull block 3210 drives the push-pull rod 329 and the push-pull cross bar 326 to move inwards, thereby clamping the metal fixing plate, and the thickness induction clamping plate 3213 senses the thickness of the metal fixing plate;

[0054] Step 6: Under the control of the control mechanism 3, the laser cutting machine 3218 precisely laser cuts the metal fixing plate to ensure that the cutting path and depth meet the design requirements;

[0055] Step 7: After cutting is completed, the bidirectional hydraulic push rod 324 works in the reverse direction, moves the laser cutting machine 3218 and the thickness induction clamping plate 3213 back to the initial position, and prepares for the next cutting operation.

[0056] Working principle of the present invention: When laser cutting of the metal fixing plate is required, first start the double-direction hydraulic push rod 324 at the bottom of the double-direction push rod connecting plate 321. After the double-direction hydraulic push rod 324 is started, it pulls two push-pull blocks 3210 to move inward. The movement of the two push-pull blocks 3210 drives the push rod 329 to pull two push-pull cross bars 326 to slide inward on the inner wall of the C-shaped chute frame 325. When the two push-pull cross bars 326 slide inward, two groups of hinge blocks 327 pull two groups of rotating rods 328 with opposite orientations to rotate. Then, through the two groups of rotating rods 328, the L-shaped receiving and expanding rod 3212 is pulled to slide inward between the connecting block 313 and the connecting block 316, thereby driving the two groups of thickness sensing clamping plates 3213 to move inward to clamp and fix the metal fixing plate on the conveyor belt. The thickness of the metal fixing plate is sensed by the inner sides of the two groups of thickness sensing clamping plates 3213. And through this design, the problem of reduced cutting accuracy caused by the movement or vibration of the metal fixing plate during laser cutting can be effectively avoided. At the same time, when the two push rods 329 move inward, the two groups of rotating rod connecting rods 3214 drive the two groups of rotating rods 3215 to rotate. The rotation of the two groups of rotating rods 3215 further pushes the laser cutting machine connecting plate 3216 to move downward and drives the laser cutting machine 3218 at its bottom to move downward and approach the surface of the metal fixing plate fixed by the two groups of thickness sensing clamping plates 3213. At this time, the metal fixing plate can be laser cut by the laser cutting machine 3218. After the laser head of the laser cutting machine 3218 is aligned with the predetermined cutting position of the metal fixing plate, the laser cutting machine 3218 starts to work, emits a laser beam to precisely cut the metal fixing plate. During the cutting process, the movement of the laser cutting machine 3218 is precisely controlled by the control mechanism 3 to ensure that the cutting path and depth meet the design requirements. After the cutting is completed, the double-direction hydraulic push rod 324 works in the reverse direction to move the laser cutting machine 3218 and the thickness sensing clamping plates 3213 back to the initial position to prepare for the next cutting operation. The entire cutting process has a high degree of automation and is easy to operate, greatly improving the production efficiency and cutting accuracy of the hardware parts for furniture processing;

[0057] When the metal fixing plate is transported on the conveyor belt of the laser cutting device 1, when the metal fixing plate moves to the inner sides of the two hub plates 48, at this time, start the two hydraulic push rods 43. After the two hydraulic push rods 43 are started, they push the L-shaped rotating rod push block 46 to drive the L-shaped rotating rod 45 to rotate. The two L-shaped rotating rods 45 rotate around the L-shaped rotating rod hinge block 44 as the axis, and then push the pressing plate 47 to drive the hub plate 48 to move inward.
