Description

Technical Field

[0001] The present invention relates to the field of laser cutting robots, and specifically to a laser cutting robot capable of quickly loading and unloading workpieces. Background Art

[0002] Laser cutting utilizes a highly focused high-power density laser beam to irradiate a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach the ignition point. At the same time, molten material is blown away by a high-speed gas flow coaxial with the beam, thereby realizing the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces. A laser processing robot applies robot technology to laser cutting and realizes a more flexible laser cutting operation through a high-precision industrial robot. A laser cutting robot focuses a CO2 laser beam on the material surface with a focusing lens to melt the material, and at the same time blows away the melted material with a compressed gas coaxial with the laser beam, and makes the laser beam and the material move relative to each other along a certain trajectory, thereby forming a cut of a certain shape, which is an industrial cutting robot.

[0003] During the process of processing workpieces by existing laser cutting robots, in order to improve the overall processing effect, it is necessary to limit and fix the workpieces to prevent the workpieces from shifting during the processing by the laser cutting robot. During this process, after the workpiece is processed, it is also necessary for the staff to disassemble the clamping assembly to remove the processed workpiece, which greatly reduces the overall loading and unloading efficiency. Moreover, a large amount of waste is generated during the processing of workpieces by the laser cutting robot. If the waste is not cleaned for a long time, it will accumulate, thereby affecting the overall processing environment and increasing the cleaning burden on subsequent staff.

[0004] In summary, during the actual processing of the above-mentioned laser cutting robot, the staff needs to repeatedly disassemble its clamping assembly, which greatly reduces the overall loading and unloading efficiency. At the same time, a large amount of waste is generated during the processing of workpieces by the laser cutting robot, and the subsequent cleaning wastes a lot of manpower and material resources. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a laser cutting robot capable of quickly loading and unloading workpieces to solve the technical problems that during the processing, the staff needs to repeatedly disassemble its clamping assembly, and at the same time, a large amount of waste is generated during the processing of workpieces by the laser cutting robot, and the subsequent cleaning wastes a lot of manpower and material resources.

[0006] To achieve the above object, the present invention provides the following technical solution: A laser cutting robot capable of quickly loading and unloading, comprising a processing table and a laser cutting assembly. A turntable is rotatably provided on the top of the processing table, and a plurality of groups of processing chambers are provided on the top of the turntable. A sliding clamping plate is slidably provided in the processing chamber, and a first pulley column is connected through the turntable on one side of the sliding clamping plate. A special-shaped rotating groove cooperating with the first pulley column is provided in the processing table, and the end face in the special-shaped rotating groove is located at the laser cutting assembly. Protective plates are elastically provided on both the sliding clamping plate and the inner side of the processing chamber. One end of the protective plate is connected with a guide post. A slide bar is slidably provided in the vertical direction in the sliding clamping plate, and a guide post hole is provided on the slide bar. The guide post hole and the guide post are eccentrically arranged. A support plate cooperating with the slide bar is rotatably provided at the bottom of the protective plate on one side of the sliding clamping plate.

[0007] By adopting the above technical solution, the sliding clamping plate is driven by the cooperation of the special-shaped rotating groove and the first pulley column to perform the limiting clamping work on the workpiece to be processed. Under the action of the tooth block and the special-shaped gear, the support plate is flipped to the side wall of the sliding clamping plate. At this time, the support plate will release the support work on the bottom of the workpiece. At this time, the processing waste generated by the laser cutting assembly will be discharged into the collection tank. Through the cooperation of the elastic component and the special-shaped rotating groove, the first pulley column drives the sliding clamping plate to release the limiting work on the workpiece, which is convenient for the staff to take it out later.

[0008] The present invention is further provided that a heat exchange plate is slidably provided at the bottom of the turntable, and a second pulley column is connected to the bottom of the heat exchange plate. An arc-shaped slide rail cooperating with the second pulley column is provided on the processing table at the bottom of the turntable, and the open end of the arc-shaped slide rail is located at the laser cutting assembly.

[0009] By adopting the above technical solution, under the action of the second pulley column, the heat exchange plate is located in the processing chamber and contacts the workpiece. When moving to the laser cutting assembly, the heat exchange plate will not affect the processing of the laser cutting assembly at this time. After processing is completed, the second pulley column slides onto the arc-shaped slide rail again. At this time, the heat exchange plate contacts the processed workpiece and cools it through itself. At the same time, the workpiece is lifted under the action of the second pulley column and the arc-shaped slide rail.

[0010] The present invention is further provided that a part of one side of the slide bar is provided with a tooth block, and a special-shaped gear is meshed on one side of it. One end of the special-shaped gear is connected to the support plate.

[0011] By adopting the above technical solution, when the guide post is inserted into the guide post hole of the slide bar, it will drive the slide bar to slide upward. During this process, the tooth block on one side of the slide bar will drive the special-shaped gear to rotate, thereby realizing the rotation of the support plate by a certain angle.

[0012] The present invention is further configured such that a stepper motor is provided at the bottom of the processing table, and the output end of the stepper motor is connected to the turntable.

[0013] By adopting the above technical solution, under the action of the stepper motor, it is convenient for the staff to control the rotation angle and rotation frequency of the turntable, and it is convenient for the staff to adjust according to the processing conditions of the workpiece to be processed, further improving the overall processing efficiency of the device.

[0014] The present invention is further configured such that waste openings are provided at the processing chamber on the processing table, and a collection tank is connected to the bottom of the waste openings.

[0015] By adopting the above technical solution, during the processing by the laser cutting assembly, the workpiece will be locally cut, resulting in some waste. The waste will fall to the waste opening due to its own gravity, and at the same time, it will be collected by the collection tank at the bottom, which is convenient for reducing the collection burden of the subsequent staff.

[0016] The present invention is further configured such that the heat exchange plate is integrally arranged in a frustum shape.

[0017] By adopting the above technical solution, in the frustum shape setting, during the cutting of the workpiece by the laser cutting assembly, the waste will fall to both sides along the edge of the heat exchange plate, thereby preventing the waste from accumulating on the top of the heat exchange plate during the cutting process, and further improving the overall processing environment.

[0018] The present invention is further configured such that the second pulley column and the arc-shaped slide rail are arranged in a smooth state, and both ends of the arc-shaped slide rail are arranged in an arc shape.

[0019] By adopting the above technical solution, the smooth setting is convenient for reducing the sliding friction between the two, ensuring that the second pulley column will not get stuck when sliding on the arc-shaped slide rail. At the same time, the arc-shaped setting at both ends is convenient for the second pulley column to easily slide into the arc-shaped slide rail after passing through the laser cutting assembly, ensuring the stability of the overall operation of the device.

[0020] The present invention is further configured such that a plurality of compression springs are provided on one side of the sliding clamping plate, and the other end of the compression spring is connected to the protection plate.

[0021] By adopting the above technical solution, when the first pulley column slides in the special-shaped rotating groove, it will drive the sliding clamping plate to clamp the workpiece to be processed. During this process, the protection plate on the inner side of the sliding clamping plate will first contact the side wall of the workpiece, and then by squeezing the compression spring inside, the compression spring itself will be in a compressed state. After the subsequent processing is completed, when the first pulley column continues to rotate in the special-shaped rotating groove, the protection sleeve will be reset and slide under the reset action of the compression spring.

[0022] The present invention is further configured such that the collection groove and the processing table are detachably arranged.

[0023] By adopting the above technical solution, the detachable arrangement facilitates the staff to uniformly process the waste in the collection groove, effectively reducing the subsequent waste collection burden.

[0024] The present invention is further configured such that the top of the processing chamber is open.

[0025] By adopting the above technical solution, the open arrangement facilitates the staff to place the workpiece to be processed inside the processing chamber.

[0026] In summary, the present invention mainly has the following beneficial effects: 1. In the process of the stepping motor driving the turntable to rotate, the first pulley column will rotate in the special-shaped rotating groove on the processing table. In the initial state, the staff can place the workpiece to be processed inside the sliding clamping plate. Subsequently, during the rotation of the turntable, through the cooperation of the special-shaped rotating groove and the first pulley column, the sliding clamping plate is driven to perform the limit clamping work on the workpiece to be processed. Then, after the laser cutting assembly finishes processing it, the turntable continues to rotate. Through the cooperation of the elastic component and the special-shaped rotating groove, the first pulley column drives the sliding clamping plate to release the limit work on the workpiece, facilitating the staff to take it out later. During this process, there is no need for the staff to manually clamp the workpiece, which speeds up the loading and unloading of the workpiece and improves the overall processing effect of the workpiece; 2. When the first pulley column drives the sliding clamping plate to clamp the workpiece, the protection sleeve will first contact the side wall of the workpiece. At this time, the protection sleeve will drive the guide post on one side to move towards the inside of the sliding clamping plate. By inserting the guide post into the guide post hole of the sliding rod, since the guide post and the guide post hole are eccentrically arranged, the guide post will drive the sliding rod to move upward. Through the action of the tooth block and the special-shaped gear, the support plate is flipped to the side wall of the sliding clamping plate. At this time, when the sliding clamping plate completes the clamping work on the workpiece, the support plate will release the support work on the bottom of the workpiece. At this time, during the processing by the laser cutting assembly, the processing waste generated will be discharged into the collection groove through the waste outlet at the bottom, thereby preventing a large amount of waste from accumulating on the processing table and reducing the subsequent cleaning burden; 3. In the present invention, an arc-shaped slide rail is provided at the top of the workbench and at the bottom of the turntable, and the open end of the arc-shaped slide rail is located at the laser cutting assembly. During the rotation of the turntable driven by the stepper motor, the heat exchange plate is located in the processing chamber and contacts the workpiece under the action of the second pulley column. When moving to the laser cutting assembly, the heat exchange plate moves downward under its own gravity to release the contact with the workpiece. At this time, the heat exchange plate does not affect the processing of the laser cutting assembly. Subsequently, after the processing is completed, the second pulley column slides back onto the arc-shaped slide rail. At this time, the heat exchange plate contacts the processed workpiece and cools it by itself. At the same time, under the action of the second pulley column and the arc-shaped slide rail, the workpiece is lifted, accelerating the overall cooling and facilitating subsequent workers to pick it up.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will be described below according to its overall structure.

[0031] Embodiment 1 A laser cutting robot capable of quickly loading and unloading materials, as Figures 1 - 10 shown, includes a processing table 1, a turntable 2, a laser cutting assembly 4, a sliding mechanism, a clamping mechanism and a supporting mechanism. A stepping motor 12 is provided at the bottom of the processing table 1, and the output end of the stepping motor 12 is connected to the turntable 2. Under the action of the stepping motor 12, it is convenient for the staff to control the rotation angle and rotation frequency of the turntable 2, and it is convenient for the staff to adjust according to the processing conditions of the workpiece to be processed, further improving the overall processing efficiency of the device. At the same time, a plurality of processing chambers 3 are opened at the top of the turntable 2. The staff places the workpiece to be processed in the processing chamber 3, and then drives the turntable 2 to rotate by a certain angle under the action of the stepping motor 12. A sliding clamping plate 5 is slidably arranged in the processing chamber 3, and a first pulley column 11 is connected through the turntable 2 on one side of the sliding clamping plate 5. An irregular rotating groove 14 matching the first pulley column 11 is opened in the processing table 1, and the end surface in the irregular rotating groove 14 is located at the laser cutting assembly 4. During the rotation of the turntable 2, the sliding clamping plate 5 is driven to perform the limiting clamping work on the workpiece to be processed through the cooperation of the irregular rotating groove 14 and the first pulley column 11, and then the laser cutting assembly 4 performs laser cutting work on the clamped workpiece; Moreover, protective plates 7 are elastically arranged on the inner sides of the sliding clamping plate 5 and the processing chamber 3. One end of the protective plate 7 is connected to a guide post 17. A slide bar 20 is slidably arranged vertically in the sliding clamping plate 5, and a guide post hole 21 is arranged on the slide bar 20. During the process of the first pulley post 11 driving the sliding clamping plate 5 to clamp the workpiece, the protective plate 7 will first contact the side wall of the workpiece. At this time, the protective plate 7 will drive the guide post 17 on one side to move towards the inside of the sliding clamping plate 5. By inserting the guide post 17 into the guide post hole 21 of the slide bar 20, since the guide post hole 21 and the guide post 17 are eccentrically arranged, the guide post 17 will drive the slide bar 20 to move upward. A tooth block 19 is partially arranged on one side of the slide bar 20, and a special-shaped gear 18 is engaged with it on one side. One end of the special-shaped gear 18 is connected to the support plate 8. When the guide post 17 is inserted into the guide post hole 21 of the slide bar 20, it will drive the slide bar 20 to slide upward. During this process, the tooth block 19 on one side of the slide bar 20 will drive the special-shaped gear 18 to rotate, thereby realizing driving the support plate 8 to rotate by a certain angle, so that the support plate 8 is flipped to the side wall of the sliding clamping plate 5; Since waste openings 10 are provided at the processing chamber 3 on the processing table 1, and a collection tank 13 is connected to the bottom of the waste opening 10. During the process of the laser cutting assembly 4 performing processing, the workpiece will be locally cut, and thus some waste will be generated. The waste will fall towards the waste opening 10 due to its own gravity, and at the same time, it will be collected by the collection tank 13 at the bottom, which is convenient for reducing the collection burden of subsequent staff. Subsequently, the stepping motor 12 continues to drive the turntable 2 to rotate by a certain angle. During this process, the first pulley post 11 will continue to slide in the special-shaped rotating groove 14. Under the action of the elastic component, the sliding clamping plate 5 is reset, so that the first pulley post 11 drives the sliding clamping plate 5 to release the limiting work on the workpiece, which is convenient for the subsequent staff to take it out. During this process, there is no need for the staff to manually clamp the workpiece, which speeds up the loading and unloading of the workpiece and improves the overall processing effect of the workpiece.

[0032] Please refer to Figure 10 , a group of compression springs 16 are arranged on one side of the sliding clamping plate 5, and the other end of the compression spring 16 is connected to the protective plate 7. When the first pulley post 11 slides in the special-shaped rotating groove 14, it will drive the sliding clamping plate 5 to clamp the workpiece to be processed. During this process, the protective plate 7 on the inner side of the sliding clamping plate 5 will first contact the side wall of the workpiece, and then by squeezing the inner compression spring 16, the compression spring 16 itself is in a compressed state. After the subsequent processing is completed, when the first pulley post 11 continues to rotate in the special-shaped rotating groove 14, the protective plate 7 is reset and slides under the reset action of the compression spring 16.

[0033] Embodiment 2 Please refer toFigure 1 , Figure 4 and Figure 5 , a laser cutting robot capable of rapid loading and unloading is shown. Its overall structure is similar to that of the first embodiment. A heat exchange plate 6 is slidably arranged at the bottom of the turntable 2, and a second pulley column 15 is connected to the bottom of the heat exchange plate 6. An arc-shaped slide rail 9 that cooperates with the second pulley column 15 is arranged on the processing table 1 at the bottom of the turntable 2, and the open end of the arc-shaped slide rail 9 is located at the laser cutting assembly 4. During the rotation of the turntable 2 under the action of the stepping motor 12, the heat exchange plate 6 is located in the processing chamber 3 and contacts the workpiece under the action of the second pulley column 15. When moving to the laser cutting assembly 4, the heat exchange plate 6 moves downward under its own gravity to release the contact with the workpiece. At this time, the heat exchange plate 6 does not affect the processing of the laser cutting assembly 4. Subsequently, after processing is completed, the second pulley column 15 slides back onto the arc-shaped slide rail 9. At this time, the heat exchange plate 6 contacts the processed workpiece and cools it by itself. At the same time, under the action of the second pulley column 15 and the arc-shaped slide rail 9, the workpiece is lifted, accelerating the overall cooling and facilitating subsequent workers to pick it up.

[0034] Please refer to Figure 1 and Figure 4 , in which the heat exchange plate 6 is integrally arranged in a frustum shape. During the cutting of the workpiece by the laser cutting assembly 4 in the frustum shape setting, the waste will fall to both sides through the edge of the heat exchange plate 6, thereby preventing the accumulation of waste during cutting on the top of the heat exchange plate 6, further improving the overall processing environment. Subsequently, under the action of the arc-shaped slide rail 9 and the second pulley column 15, the heat exchange plate 6 contacts the processed workpiece, and the overall cooling efficiency of the workpiece is accelerated during this process, facilitating subsequent workers to directly take it out from the processing chamber 3.

[0035] The working principle of the present invention is as follows: When in use, the workpiece to be processed is placed in the processing chamber 3 of the turntable 2, and the workpiece is supported by the sliding clamping plate 5 and the support plate 8 inside the processing chamber 3 to prevent the workpiece from falling downward. At the same time, the turntable 2 is driven to rotate under the action of the stepping motor 12. Since one side of the sliding clamping plate 5 is elastically connected with a first pulley column 11, when driving the workpiece to rotate to the laser cutting assembly 4, the sliding clamping plate 5 clamps the workpiece under the cooperation of the first pulley column 11 and the special-shaped rotating groove 14 in the processing table 1, preventing the workpiece from shifting during the processing by the laser cutting assembly 4. At the same time, when the sliding clamping plate 5 slides inward to clamp the workpiece, the protection plate 7 inside the sliding clamping plate 5 will contact the side of the workpiece first; At this time, the protection plate 7 drives the guide post 17 to move towards the inside of the sliding clamping plate. Subsequently, it is inserted into the guide post hole 21 of the sliding rod 20. Since the sliding rod 20 and the guide post hole 21 are eccentrically arranged, the sliding rod 20 will be driven to slide upward during this process. Under the meshing of the tooth block 19 and the special-shaped gear 18, the support plate 8 rotates towards the side wall of the sliding clamping plate 5. At this time, the support plate 8 releases the support for the workpiece, preventing the bottom support plate 8 from causing obstruction to the laser cutting assembly 4 during the processing process. During the processing of the laser cutting assembly 4 at this time, the processing waste generated will be discharged into the collection tank 13 through the waste outlet 10 at the bottom, thereby preventing a large amount of waste from accumulating on the processing table 1. Subsequently, after the processing is completed, under the action of the elastic component, the first pulley column 11 is reset in the special-shaped rotating groove 14, so that the sliding clamping plate 5 releases the clamping of the workpiece, and at the same time, the support plate 8 is reset to support the workpiece again. During this process, there is no need for the staff to manually clamp the workpiece, which speeds up the loading and unloading of the workpiece.

[0036] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
