Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Example 1

[0035] See Figures 1 to 6 The present invention provides a cutting device for building decorative panels, including a frame 1, two parallel slide rails 2 fixedly arranged on one side of the frame 1, a base 3 slidably arranged on the slide rails 2, two sets of robotic arms 4 arranged on the base 3, and a cutting machine 5 for cutting panels installed on the two sets of robotic arms 4.

[0036] The frame 1 is also equipped with several sets of clamping mechanisms 6 for fixing the sheet metal, and the multiple sets of clamping mechanisms 6 are linked together.

[0037] When using this device, the board is placed on the frame 1 and fixed by the clamping mechanism 6. According to the cutting requirements, the position of the moving base 3 on the slide rail 2 is adjusted to adjust the position of the cutting machine 5 in the length direction of the board so that the cutting blade is aligned with the accurate position to be cut on the board. During cutting, the user operates the cutting machine 5 to cut the fixed building decoration board.

[0038] The robotic arm 4 includes a mounting base 7 fixedly mounted on the base 3. Two lower folding arms 8 are rotatably mounted on the mounting base 7. An intermediate section 9 is rotatably mounted on the movable end of the two lower folding arms 8. Two upper folding arms 10 are rotatably mounted on the intermediate section 9. A mounting frame 11 is rotatably mounted on the movable end of the two upper folding arms 10. The cutting machine 5 is fixed on the mounting frame 11.

[0039] A pull spring 12 is provided at the middle of the mounting base 7 and a lower folding arm 8 located below;

[0040] An upper tension spring 13 is provided at the middle of the intermediate section 9 and the lower upper folding arm 10.

[0041] Under the action of the pull spring 12 and the pull spring 13, the robotic arm 4 can support the cutting machine 5, keeping the cutting machine 5 in a suitable and stable spatial position. Without the application of external force, the cutting machine 5 is above the frame 1, which makes it convenient for users to disassemble and assemble the board.

[0042] When the user cuts the board, by pulling the cutting machine 5 to the cutting position, the upper folding arm 10 and the lower folding arm 8 also dynamically adjust their own angles according to the cutting machine 5. At this time, the upper tension spring 13 and the lower tension spring 12 are stretched. As the cutting machine 5 cuts, the user controls the movement of the cutting machine 5 to achieve the cutting of the board. Under the combined action of the upper folding arm 10 and the lower folding arm 8, the cutting machine 5 can cut the board in a straight line.

[0043] After the cutting is completed, the user releases the force applied to the cutting machine 5, and the cutting machine 5 returns to its original position under the action of the lower tension spring 12 and the upper tension spring 13, making it easier for the user to disassemble the board.

[0044] Each clamping mechanism 6 includes a bidirectional lead screw 14 rotatably mounted on the frame 1, a transmission rod 15 rotatably mounted on the frame 1 located on one side of the bidirectional lead screw 14, and two sets of opposing clamping units 16 slidably mounted on the transmission rod 15. The two sets of clamping units 16 move in opposite directions through the bidirectional lead screw 14.

[0045] A sprocket 17 is fixedly mounted at one end of the bidirectional lead screw 14, and the sprockets 17 of two adjacent clamping mechanisms 6 are connected by a chain 18.

[0046] A handwheel is coaxially fixed on a sprocket 17 located at one end. By turning the handwheel, the user can achieve the linkage of the bidirectional lead screws 14 of multiple clamping mechanisms 6. When the board is placed on the frame 1, the user can turn the handwheel to move the two clamping units 16 of the clamping mechanism 6 toward the board, so that the clamping units 16 can fix the board and adapt to different sizes of boards. Whether it is a narrow wooden strip board for interior decoration frame or a wide and heavy stone countertop material, as long as it is placed on the frame 1, turning the handwheel can automatically and accurately adjust the position of the clamping unit 16 to fit tightly against the edge of the board for fixation. This breaks the bottleneck of the traditional clamping device's limitation on the size of the board, expands the application range of the cutting device, and eliminates the need for users to prepare multiple clamping tools for different sizes of boards, reducing equipment purchase costs and space occupation.

[0047] The synchronous control of multiple clamping mechanisms 6 by a single handwheel greatly simplifies the operation process. Operators do not need to perform tedious individual debugging of each clamping unit 16. They can drive the entire clamping system to work simply by standing in a fixed position and turning the handwheel. This not only saves a lot of operation time, but also enables the quick fixation of the sheet metal in batch cutting operations, significantly improving work efficiency. It also reduces the labor intensity of operators and reduces fatigue caused by frequent walking and repetitive operations, allowing operators to devote more energy to controlling the cutting accuracy.

[0048] A swing arm 19 is fixedly installed at one end of the transmission rod 15. The movable ends of the swing arms 19 of the multiple clamping mechanisms 6 are all linked by a linkage rod 20. A wrench is fixedly installed on one of the swing arms 19 near the handwheel. The user can realize the linkage of multiple transmission rods 15 by operating the wrench, so that multiple clamping mechanisms 6 can work together to clamp the plate from different sides in all directions.

[0049] The clamping unit 16 includes a slider 21 that is slidably disposed on the transmission rod 15. The slider 21 is threadedly connected to one end of the bidirectional lead screw 14. A fixed seat 22 is disposed in the middle of the slider 21. A sleeve 23 is fixedly disposed on the fixed seat 22. A vertical rod 24 is disposed inside the sleeve 23.

[0050] When the bidirectional lead screw 14 rotates, it drives the slider 21 to move along the axial direction of the bidirectional lead screw 14, which in turn drives the clamping unit 16 to approach the plate, thereby fixing the plate with the clamping unit 16.

[0051] A pressure rod 25 is fixedly installed at the upper end of the vertical rod 24, and a pressure head is fixedly installed at the movable end of the pressure rod 25;

[0052] Two sets of sliding grooves 26 are provided opposite to each other on the side wall of the sleeve 23. The lower part of the sliding groove 26 is vertical and the upper part is spiral.

[0053] Two guide rods 27 are fixedly installed in the middle of the vertical rod 24. Each guide rod 27 slides in one of the grooves 26. The projections of the guide rod 27 and the pressure rod 25 on the horizontal plane coincide. When the guide rod 27 of the vertical rod 24 is on the vertical part of the groove 26, the pressure rod 25 is above the board. As the vertical rod 24 moves downward, the board is fixed by the pressure head. When the guide rod 27 of the vertical rod 24 is on the spiral part of the groove 26, the pressure rod 25 rotates a certain angle with the groove 26. The pressure rod 25 and the pressure head rotate to one side of the board, making it easy for the user to remove the board.

[0054] The vertical part of the slide 26 is relatively long, which can accommodate plates of different thicknesses. If the plate is thick, the guide rod 27 is located at the upper end of the vertical part of the slide 26. If the plate is thin, the guide rod 27 is located at the lower end of the vertical part of the slide 26. This allows the clamping mechanism 6 to clamp plates of different thicknesses without the need for a complex adjustment mechanism.

[0055] The lower end of the vertical rod 24 is provided with several annular protrusions 28, and a groove is formed between two adjacent protrusions 28;

[0056] A gear 29 is rotatably mounted inside the slider 21. The gear 29 slides axially and is fixed radially to the transmission rod 15. The teeth of the gear 29 mesh with the groove.

[0057] When it is necessary to fix the board, the user controls the position of the linkage 20 to drive multiple swing arms 19 to rotate, which in turn drives the transmission rod 15 to rotate. When the transmission rod 15 rotates, it drives the gear 29 to rotate. Under the action of the teeth and grooves of the gear 29, the vertical rod 24 moves downward. When the vertical rod 24 moves, under the action of the slide 26 and the guide rod 27, the pressure rod 25 swings, so that the pressure rod 25 is above the board, which is convenient for clamping and fixing the board.

[0058] The upper ends of the grooves 26 of the two clamping units 16 rotate in opposite directions.

[0059] The upper ends of the two slides 26 rotate in opposite directions, so that the pressure rods 25 of the two clamping units 16 can rotate relative to each other when rotating, which improves the aesthetics of the equipment.

[0060] A ratchet 30 is fixedly installed on the frame 1. The ratchet 30 is coaxial with the adjacent transmission rod 15. A fixed rod is fixedly installed on a swing arm 19 near the ratchet 30. A pawl 31 is rotatably installed on the movable end of the fixed rod. The pawl 31 cooperates with the ratchet 30.

[0061] A torsion spring is installed between the pawl 31 and the fixed rod.

[0062] When it is necessary to fix the plate, the user controls the position of the linkage 20 to drive multiple swing arms 19 to rotate. Among them, when the swing arm 19 with the fixed rod is rotated, it drives the pawl 31 to move. Since a torsion spring is set between the pawl 31 and the fixed rod, the tooth end of the pawl 31 is tightly engaged in the tooth groove of the ratchet 30.

[0063] As the swing arm 19 rotates, the pressure head presses against the plate, thus fixing the plate. The user can release the force applied to the linkage 20. Since the pawl 31 is engaged in the groove of the ratchet, it can effectively prevent the transmission rod 15 from reversing, thereby preventing the clamping unit 16 from releasing the plate and ensuring the stability of the plate during the fixing process.

[0064] After the board is cut, the user applies force to the pawl 31 to disengage it from the tooth groove. At this time, the reverse moving linkage 20 drives the transmission rod 15 to reverse, causing the clamping unit 16 to move in the opposite direction and release the clamp on the board, so that the user can remove the board.

[0065] When using this invention, the board is placed on the frame 1 and fixed by the clamping mechanism 6. According to the cutting requirements, the position of the moving base 3 on the slide rail 2 is adjusted to adjust the position of the cutting machine 5 in the length direction of the board so that the cutting blade is aligned with the accurate position to be cut on the board. During cutting, the user operates the cutting machine 5 to cut the fixed building decoration board.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
