[0002] Laser cutting technology, with its advantages of high cutting precision, high efficiency, and small heat-affected zone, has been widely used in metal processing, machinery manufacturing, and other fields, especially in the batch cutting of small and medium-sized workpieces. However, existing laser cutting equipment has many shortcomings: some equipment is only designed with a single or dual station, which limits the number of workpieces that can be carried at one time and results in low batch processing efficiency; at the same time, the debris generated during the cutting process tends to accumulate in the gap between the carrier plate or the fixture, and the dust spreads seriously, which not only interferes with the cutting precision but also pollutes the working environment.

[0003] Therefore, those skilled in the art have provided a robotic laser cutting device to solve the problems mentioned in the background art. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A robotic laser cutting device includes a frame 1, a support base 2 is fixedly installed on the front side of the bottom end inside the frame 1, a robot arm base 3 is installed on the top of the support base 2 by bolts, a multi-axis linkage robot arm 4 is provided on the top of the robot arm base 3, and a laser cutting head 5 is installed on the output end of the multi-axis linkage robot arm 4.

[0027] A bearing seat 6 is fixedly installed on the rear side of the bottom of the frame 1 by welding. A rotary table 7 is fixedly installed on the top of the bearing seat 6. A carrier plate 8 is fixedly connected to the top output end of the rotary table 7. A clamp 9 is vertically installed at the four corners of the top of the carrier plate 8. The workpiece 10 to be cut is clamped and fixed on the clamp 9, and the four clamps 9 are symmetrically distributed along the central axis of the carrier plate 8.

[0028] Using the above technical solutions, the front multi-axis linkage robot 4 can drive the laser cutting head 5 to flexibly adjust the cutting angle and position to adapt to the cutting needs of complex workpieces; the four sets of clamps 9 symmetrically distributed at the four corners of the carrier plate 8 along the central axis can simultaneously and independently clamp four workpieces 10 to be cut, realizing multi-workpiece carrying in a single operation; with the rotation function of the rotary table 7, after a set of workpieces is cut, the rotary table 7 can drive the carrier plate 8 to precisely rotate to the working area of ​​the next set of workpieces corresponding to the laser cutting head 5, and the workstation can be switched without stopping the machine to disassemble and install workpieces, which greatly shortens the operation interval time.

[0029] The rotary table 7 includes a rotary seat 71 and a rotary disk 72 disposed on the top of the rotary seat 71. The rotary seat 71 can drive the rotary disk 72 to rotate around its own axis. The top of the rotary disk 72 is detachably fixed to the carrier plate 8 by bolts.

[0030] Using the above technical solution, the rotary seat 71 can drive the rotary disk 72 to rotate stably around its own axis, so that multiple workpieces 10 to be cut on the carrier plate 8 can rotate synchronously with the rotary disk 72. With the movement of the multi-axis linkage robot 4, the cutting operation of workpieces at different positions can be completed in sequence, which greatly shortens the operation interval time and further improves the batch cutting efficiency. Among them, the rotary seat 71 can use a servo motor and planetary gear reduction mechanism commonly used in the prior art to drive the rotary disk 72 to rotate stably around its own axis. Since the relevant driving technology is a well-known technology in the field of mechanical transmission, it will not be described in detail.

[0031] The four corners of the carrier plate 8 are integrally formed with mounting flanges 81, and the bottom end of the clamp 9 is installed on the mounting flanges 81 by bolts passing through the mounting holes.

[0032] Using the above technical solutions, the mounting flanges 81, which are integrally formed at the four corners of the carrier plate 8, can provide a precise installation reference for the fixture 9, while also facilitating the disassembly and maintenance of the fixture.

[0033] The clamp 9 includes a drive base 91 and a support sleeve 92 installed at the output end of the drive base 91;

[0034] The outer wall of the tensioning sleeve 92 is provided with multiple slits arranged in a ring array. The slits extend along the axial direction of the tensioning sleeve 92 to its top opening. The multiple slits divide the top of the tensioning sleeve 92 into a multi-lobed structure. The drive seat 91 can drive the opening of the tensioning sleeve 92 to retract or open radially.

[0035] A positioning pin 101 is integrally fixed to the middle of the bottom end of the workpiece 10 to be cut. The positioning pin 101 is inserted into the inner side of the support sleeve 92 from the top opening of the support sleeve 92.

[0036] Using the above technical solution, after the positioning pin 101 is inserted into place, the drive seat 91 drives the opening of the support sleeve 92 to radially retract, so that the inner wall of the sleeve is tightly attached to the outer wall of the positioning pin 101. The radial clamping force achieves stable fixation of the workpiece, effectively avoiding radial movement, axial displacement or rotational deviation of the workpiece during the cutting process, and providing reliable positioning guarantee for high-precision laser cutting. Among them, the driving method of the drive seat 91 driving the support sleeve 92 to retract can adopt the pneumatic push rod drive, hydraulic push rod drive or screw drive commonly used in the existing technology. Such driving technology is mature in the field of mechanical clamping, has the characteristics of stable power and precise control, and can meet the retraction action requirements of the support sleeve 92. It is a commonly used technology, so it will not be elaborated further.

[0037] The top of the carrier plate 8 is detachably connected to a protective cover 14 by screws. The protective cover 14 has an isosceles triangular cross section, and the two inclined surfaces of the triangular structure are set at an angle.

[0038] Using the above technical solution, the protective cover 14 on the carrier plate 8 adopts an isosceles triangular cross-section design. Its inclined surface can guide the cutting debris to slide down naturally. During the cutting process, the debris generated by multiple workpieces will slide down naturally along the inclined surface to the edge of the carrier plate 8 or the debris collection area preset by the equipment under the action of gravity, so as to avoid the debris from accumulating on the surface of the carrier plate 8, getting stuck in the gap between the fixture 9 and the workpiece, or adhering to the surface of the workpiece 10 to be cut and affecting the subsequent cutting accuracy.

[0039] A dust collection box 11 is installed at the top of the frame 1. The dust collection box 11 is equipped with a pump body for providing negative pressure. The output end of the dust collection box 11 is connected to a dust collection pipe 12, which extends vertically into the interior of the frame 1. A wide-angle dust adsorption hood 13 is installed horizontally at the bottom of the dust collection pipe 12. One end of the wide-angle dust adsorption hood 13 opens towards the working area of ​​the laser cutting head 5.

[0040] Using the above technical solutions, the dust collection box 11, combined with the pump body, can generate negative pressure, and efficiently collect the smoke and dust generated by laser cutting through the dust collection pipe 12 and the wide-angle smoke and dust adsorption hood 13. The wide-angle design can cover the cutting work area, reduce the spread of smoke and dust, improve the working environment, protect the health of operators, and prevent smoke and dust from adhering to the equipment and affecting the accuracy, which meets the requirements of environmental protection and equipment maintenance.

[0041] Working principle:

[0042] The workpiece 10 to be cut is inserted into the support sleeve 92 of the four corner clamps 9 of the carrier plate 8 through the bottom positioning pin 101. The drive seat 91 drives the support sleeve 92 to close and fix the workpiece. Then the rotary table 7 drives the carrier plate 8 to rotate and switch the workpiece to the working area of ​​the laser cutting head 5. The multi-axis linkage robot 4 drives the laser cutting head 5 to complete the cutting operation. During the process, the protective cover 14 guides the debris to slide down and blocks the splash. The dust collection box 11 collects the dust through the wide-angle dust adsorption cover 13 under the action of the pump body. After the cutting is completed, the rotary table 7 continues to rotate to switch the next set of workpieces, realizing continuous batch cutting.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
