Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a laser cutting device for plates that combines fastening and cleaning functions. Background Technology

[0002] When cutting sheet metal, it is necessary to fix the sheet metal in place. Currently, the main problems encountered during sheet metal cutting are as follows: (1) Either press the plate onto the cutting table by a clamping device or adsorb the plate onto the cutting table by a vacuum adsorption device; that is, using only one fixing method results in the plate being unstable.

[0003] (2) When vacuum adsorption is used, if dust or particulate matter is attached to the adsorption surface of the board, air leakage is likely to occur, resulting in unstable adsorption. If the board needs to be cleaned, it can only be cleaned manually by wiping the adsorption surface of the board with a hand-held cleaning tool, which is inefficient. Summary of the Invention

No manual cleaning is required, which improves the cleaning efficiency of the plate. After the plate is cleaned, it is more conducive to the adsorption of the vacuum adsorption stage, which improves the stability of the plate. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-5 A laser cutting device for sheet metal, which combines clamping and cleaning functions, includes a frame 1, a clamping system 2, a multi-axis linkage system 3, and a cutting system 4. The multi-axis linkage system 3 is mounted on the upper part of the frame 1, and the cutting system 4 is mounted on the output end of the multi-axis linkage system 3. The clamping system clamps the sheet metal, the multi-axis linkage system controls the position of the cutting system, and the cutting system cuts the sheet metal.

[0019] The invention also includes a control system. A control cabinet is provided on one side of the frame, and a PLC controller is installed in the control cabinet. The clamping system, the multi-axis linkage system and the cutting system are all electrically connected to the PLC controller.

[0020] The multi-axis linkage system 3 includes a hydraulic cylinder 31, a lifting seat 32 connected to the telescopic end of the hydraulic cylinder, an X-axis displacement mechanism 33 mounted on the lifting seat, an X-axis slide 34 connected to the X-axis displacement mechanism, a Y-axis displacement mechanism 35 mounted on the X-axis slide, and a Y-axis slide 36 connected to the Y-axis displacement mechanism. The cutting system 4 is mounted on the bottom surface of the Y-axis slide 36.

[0021] Two guide rods 37 are connected to the top of the lifting seat 32. The guide rods 37 are slidably connected to the frame 1 to improve the stability of the lifting seat.

[0022] Both the X-axis displacement mechanism 33 and the Y-axis displacement mechanism 35 employ a lead screw drive mechanism, i.e., the lead screw is driven to rotate by a servo motor, thereby causing the X-axis slide 34 and the Y-axis slide 36 to perform linear motion. The lead screw drive mechanism is existing technology and will not be described in detail here.

[0023] In addition, the length of the X-axis displacement mechanism is greater than or equal to the length of the vacuum adsorption stage, the X-axis slide is perpendicular to the lifting seat and extends in the forward and backward direction, and the length of the Y-axis displacement mechanism is greater than or equal to the width of the vacuum adsorption stage, so that the cutting system can move to any area above the vacuum adsorption stage.

[0024] The cutting system 4 includes a column 41 and a laser cutting machine 42 connected to the lower end of the column. The column 41 is fixedly connected to the bottom surface of the Y-axis slide 36, and a laser cutting head 43 is mounted on the bottom surface of the laser cutting machine 42. The laser cutting machine includes a light source; preferably, a fiber laser is used as the light source in this invention. Compared with traditional CO2 lasers, fiber lasers have significant advantages such as high electro-optical conversion efficiency, good beam quality, compact size, and maintenance-free operation. After the laser is generated by the laser, it is guided to the high-speed moving laser cutting head through a high-power flexible transmission fiber to achieve laser cutting. The laser cutting machine is existing technology and can be purchased directly from the market; therefore, it will not be described in detail in this invention.

[0025] The clamping system 2 includes a vacuum adsorption table 21, a pressing mechanism 22, and a cleaning mechanism 23. The vacuum adsorption table 21 is fixed on the frame 1 and located below the cutting system 4. The pressing mechanism 22 consists of multiple sets, preferably four sets, arranged in pairs and symmetrically on both sides of the vacuum adsorption table 21. The plate is adsorbed by the vacuum adsorption table, and the plate is pressed tightly onto the vacuum adsorption table by the pressing mechanism.

[0026] The clamping mechanism 22 includes a first cylinder 221, a lifting frame 222, and a cylinder clamping device 223. The first cylinder 221 is mounted on the frame 1, and the lifting frame 222 is connected to the telescopic end of the first cylinder 221. The extension of the first cylinder 221 can drive the lifting frame 222 to rise. The cylinder clamping device 223 includes a bracket 2231, a third cylinder 2232, a connecting piece 2233, a pressure rod 2234, and a pressure plate 2235. A bracket 2231 is connected to the top surface of a lifting frame 222. A bearing plate 224 is connected to the side of the bracket 2231 facing the vacuum adsorption table. A third cylinder 2232 is mounted on the lifting frame 222. The telescopic end of the third cylinder 2232 is pivotally connected to one end of a pressure rod 2234. A connecting piece 2233 is pivotally connected to the upper end of the bracket 2231. The upper end of the connecting piece 2233 is pivotally connected to the pressure rod 2234. One end of the pressure rod 2234 is located above the vacuum adsorption table 21, and a pressure plate 2235 is connected to the end of the pressure rod 2234 facing the vacuum adsorption table. By extending the third cylinder 2232, the plate can be pressed onto the vacuum adsorption table 21. The vacuum adsorption stage 21 is connected to vertical guide rails 225 on both sides. The lifting frame 222 is provided with a sliding groove on the side facing the vacuum adsorption stage and is slidably connected to the guide rails 225 through the sliding groove to improve the stability of the lifting frame.

[0027] The top surface of the vacuum adsorption stage 21 is fixed with a panel, and the surface of the panel is distributed with multiple adsorption hole groups 211 arranged in a matrix. Flexible suction cups 212 are embedded around each adsorption hole group 211. The vacuum adsorption stage 21 is provided with a vacuum chamber, and the adsorption hole groups 211 are connected to the vacuum chamber. An air inlet pipe 213 is connected to one side of the vacuum adsorption stage 21 and is connected to a vacuum generating device.

[0028] The vacuum generating device includes a solenoid valve and a vacuum generator. The solenoid valve and the vacuum generator are electrically connected to the control system. The solenoid valve controls the opening and closing of the vacuum chamber.

[0029] The panel is made of non-magnetic, high-strength aluminum alloy or composite ceramic with excellent wear resistance. It is precision ground to ensure that the upper surface has extremely high flatness, providing a flat support benchmark for the board and preventing the board from undergoing micro-deformation under the action of adsorption force due to unevenness of the table surface.

[0030] The adsorption pore groups are evenly distributed on the panel in a matrix form. Each adsorption pore group is usually composed of multiple micropores (pore diameter of about 1-2 mm) forming a unit, which ensures the uniformity of adsorption force and avoids local stress concentration caused by a single large pore.

[0031] Flexible suction cups are installed around each or every group of suction holes on the panel. When the panel is placed on the panel, the suction cups are slightly compressed under the vacuum negative pressure, forming an elastic seal with the bottom surface of the panel. This flexible sealing method can automatically compensate for the slight unevenness of the panel itself, ensuring an effective airtight space can be formed even on rough or slightly curved surfaces, greatly improving adaptability.

[0032] The vacuum generator provides a negative pressure source for the system. The system also integrates a vacuum sensor (not shown in the figure) to monitor the negative pressure value within the chamber in real time.

[0033] The cleaning mechanism 23 includes a linear displacement mechanism 231 installed at the front and rear ends of the vacuum adsorption stage 21, and a first slide 232 and a second slide (not shown in the figure) connected to the linear displacement mechanism 231. The first slide 232 and the second slide are located at the front and rear ends of the vacuum adsorption stage 21, respectively.

[0034] The linear displacement mechanism 231 includes bearing seats 2311, a lead screw 2312, a guide rod, and a servo motor 2313. There are four bearing seats 2311, arranged in pairs, fixed to the front and rear ends of the vacuum adsorption stage 21. The lead screw 2312 is rotatably connected to two bearing seats 2311 at the same end via bearings. The guide rod is connected to the other two bearing seats 2311. The output end of the servo motor 2313 is connected to one end of the lead screw 2312. The first slide 232 has a screw hole and is threadedly connected to the lead screw 2312. The second slide has a sliding hole and is slidably connected to the guide rod through the sliding hole. When the servo motor 2313 operates, it drives the lead screw 2312 to rotate, which in turn drives the first slide 232 to move on the lead screw 2312. Simultaneously, the cleaning roller 235 drives the second slide to move on the guide rod, causing the cleaning roller 235 to move from one end of the vacuum adsorption stage 21 to the other.

[0035] The cleaning mechanism 23 also includes a second cylinder 233, a connecting plate 234, and a cleaning roller 235. There are two second cylinders 233, respectively mounted on the first slide 232 and the second slide. The extension and retraction ends of both second cylinders 233 are connected to the connecting plate 234. The cleaning roller 235 is rotatably connected between the two connecting plates 234. The cleaning roller 235 is located between the support plate 224 and the vacuum adsorption stage 21. Through the extension of the second cylinders 233, the cleaning roller 235 can be positioned above the vacuum adsorption stage 21. The cleaning roller includes a central rod and a sponge tube fixed to the periphery of the central rod. The central rod is rotatably connected to the connecting plate via bearings.

[0036] This invention also requires an air compressor to provide pneumatic power to each cylinder. It also requires a hydraulic oil supply system to supply hydraulic oil to the hydraulic cylinders.

[0037] The working principle of this invention is as follows: Figure 5 As shown, plate 5 is placed on the support plate 224 in four directions. Then, the first cylinder 221 is extended to drive the lifting frame 222 to rise, so that the plate is suspended in the air. Then, the third cylinder 2232 is extended to drive the pressure rod 2234 to rotate clockwise until the pressure plate 2235 presses the plate onto the support plate 224, so that the plate is kept stable.

[0038] Next, the second cylinder 233 is extended, causing the connecting plate 234 to rise, so that the cleaning roller 235 contacts the bottom surface of the plate 5. At this time, the cleaning roller 235 is located above the vacuum adsorption stage 21. Then, the linear displacement mechanism 231 is activated, causing the first slide 232 and the second slide to move linearly at the front and rear ends of the vacuum adsorption stage 21, thereby driving the cleaning roller 235 to move to wipe the bottom surface of the plate to prevent dust and other impurities from affecting the adsorption of the suction cup.

[0039] After cleaning, the cleaning roller 235 returns to its initial position, and then the first cylinder 221 is controlled to retract, causing the lifting frame 222 to descend and place the plate on the vacuum adsorption stage 21. At the same time, the vacuum generator is activated to generate negative pressure, which adsorbs the plate through the suction cup 212. Simultaneously, the pressure plate 2235 presses the four corners of the plate onto the vacuum adsorption stage 21, thus achieving double fastening of the plate.

[0040] Finally, the orientation of the cutting system 4 is controlled by the multi-axis linkage system 3, and the cutting system 4 is used to cut the plate.
