Description

Technical Field

[0001] The present invention relates to a multifunctional laser cutting robot, in particular to a multifunctional laser cutting robot applied to the technical field related to welding. Background Art

[0002] In the field of equipment manufacturing, raw materials are generally either plates or profiles. Plates usually refer to flat materials of different thicknesses, and profiles include H-shaped, grooved, round, L-shaped, square, and other materials according to different cross-sections. When cutting or welding plates or profiles, traditional processing methods rely on manual cutting or welding. However, since the plates or profiles are relatively long, there are many corresponding operation points, which makes the operation difficult and the manual error rate is high. Therefore, in the prior art, many processing plants use intelligent cutting or cutting robots instead of manual cutting or welding, such as the prefabricated building component cutting robot welding adjustment device disclosed in the specification of Chinese patent CN211840799U, and the flexible stacking additive manufacturing device and manufacturing method of mechanical steel structure disclosed in the specification of Chinese patent CN110788527B.

[0003] However, the processing of plates or profiles involves cutting and welding, especially cutting, which is an important process in plate processing. However, most of the processing equipment on the market currently has a single function (plates and profiles cannot be processed at the same time), resulting in the need to set up two sets of equipment in the factory for processing plates and profiles. This leads to a high requirement for the factory floor space, which invisibly increases the processing cost; or when setting up one set of equipment, for plate processing or profile processing, it is necessary to constantly change the tooling for fixing the plates or profiles on the processing station, which is cumbersome and affects the processing efficiency. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the processing of profiles and plates cannot be universal, resulting in the need for two sets of equipment, which greatly increases the processing cost.

[0005] In order to solve the above problems, the present invention provides a multifunctional laser cutting robot, comprising a ground rail, a rack is fixedly connected to the upper end of the ground rail, a column is slidably connected to the upper end of the ground rail, a plate tooling and a profile tooling are respectively arranged on the front and rear sides of the column, the plate tooling and the profile tooling are both kept parallel to the ground rail, the left and right ends of the bottom of the column are fixedly connected to the bottom plate, a control box is installed on the bottom plate, a reducer is also installed on one of the bottom plates, the rotating end of the reducer is fixedly connected to a gear meshing with the rack, the top of the column is connected to a suspension beam through a supporting rotary unit, the lower end and the left and right ends of the suspension beam are drilled with air inlet holes, a fume purification device is installed in the suspension beam, the left and right ends of the suspension beam are respectively connected to a welding unit and a cutting gun unit through an electric slide, a laser tracking device is installed on the front and rear ends of the column, the welding unit comprises a moving motor slidably connected to the suspension beam, a fixed screw rod connected to the rotating end of the moving motor, a three-axis mechanical arm threadedly connected to the fixed screw rod, and a welding assembly installed at the end of the three-axis mechanical arm;

The upper end of the shaft body of the follower gear plate is fixedly connected to the bearing plate, and the lower end of the shaft body of the follower gear plate is rotatably connected to the top plate.

[0007] The bearing plate is slidably connected to the bottom of the cross beam through an electric slide. The left and right ends of the cross beam are fixedly connected with real-time positioning units. The two real-time positioning units are respectively located in the middle of the cross beam and one end of the cross beam close to the column. An electromagnetic positioning plate is fixedly embedded in the upper end of the bearing plate. The electromagnetic positioning plate and the real-time positioning unit match each other. A tilt monitoring unit is also provided at the lower end of one of the real-time positioning units.

[0008] In the above-mentioned multifunctional cutting robot, by supporting the setting of the rotating unit, the horizontal suspension beam carrying the welding unit and the cutting gun unit can switch the workstations, and thus can adapt to the processing of profiles and plates at the same time. Compared with the existing technology, the application scope of this cutting robot is improved, and some equipment settings are effectively saved, thereby reducing processing costs.

[0009] As a further improvement of the present application, only one operating end of the cutting gun unit is provided. The cutting gun unit has a similar structure to the welding unit and also includes a dynamic motor and a three-axis robotic arm. A cutting gun assembly is installed at the end of the three-axis robotic arm on the cutting gun unit.

[0010] As a further improvement and supplement to the present application, the instant positioning unit includes an upper positioning plate fixedly connected to the cross suspension beam, a plurality of I-shaped positioning columns movably passing through the upper positioning plate, and a gasket movably mounted on the outer end of the neck of the I-shaped positioning column, the gasket is located above the upper positioning plate, and the gasket is an elastic structure.

[0011] As a further improvement and supplement to the present application, the electromagnetic positioning plate includes multiple electromagnetic segments corresponding to multiple I-shaped positioning columns and multiple isolation segments fixedly connected between two adjacent electromagnetic segments. When energized, there is a magnetic attraction between the electromagnetic segments and the corresponding I-shaped positioning columns, and the isolation segments are made of insulating material.

A light-transmitting plate is also fixedly connected to the inner wall of the shaping tube, and the light-transmitting plate is higher than the ball-binding tube.

[0015] As a further improvement of the present application, when the electromagnetic positioning plate is not powered, the distance between the lower end of the I-shaped positioning column and the electromagnetic positioning plate is less than the thickness of the gasket, and the lower end of the follower column does not contact the electromagnetic positioning plate.

[0017] In summary, by supporting the setting of the rotation unit, the cross suspension beam equipped with the cutting gun unit can switch between workstations, and thus can adapt to the processing of profiles and plates at the same time. Compared with the existing technology, it can improve the application scope of the cutting robot, effectively save some equipment settings, and thus reduce the processing cost. In addition, with the setting of the real-time positioning unit, the turning points between the cross suspension beam and the column can be set to two while ensuring the stability of the equipment, and then when switching workstations and processing narrower profiles, the rotation range can be significantly reduced, thereby effectively reducing the demand for factory area of ​​the cutting robot when switching workstations and improving convenience during use. In addition, with the setting of the tilt monitoring unit, the stability of the cross suspension beam can be monitored in real time and adjusted in time, thereby effectively ensuring the stability of the cross suspension beam and making higher precision during welding and cutting.

DETAILED DESCRIPTION

[0033] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-3A multifunctional laser cutting robot is shown, in which a represents a plate tooling, a1 represents a plate, b represents a profile tooling, b1 represents a profile, and c1 represents a rotation trajectory when the end of a horizontal suspension beam 2 is used as a rotation point, including a ground rail 3, the upper end of the ground rail 3 is fixedly connected to a rack 302, the upper end of the ground rail 3 is slidably connected to a column 1, and the front and rear sides of the column 1 are respectively provided with a plate tooling and a profile tooling, and the plate tooling and the profile tooling are both kept parallel to the ground rail 3. The left and right ends of the bottom of the column 1 are fixedly connected to a bottom plate, and a control box 4 is installed on the bottom plate. A reducer 301 is also installed on one of the bottom plates, and the rotating end of the reducer 301 is fixedly connected to a gear meshing with the rack 302. The top of the column 1 is connected to the horizontal suspension beam 2 through a supporting rotary unit. The left and right ends of the suspension beam 2 are respectively connected to the welding unit 5 and the cutting gun unit 6 through an electric slide. Laser tracking devices 101 are installed at the front and rear ends of the column 1. The two control boxes 4 are respectively used to control and program the working trajectories of the welding unit 5 and the cutting gun unit 6, so that the welding unit 5 and the cutting gun unit 6 can perform standardized welding, cutting and other operations under the established trajectory, so that when the plates or profiles are processed in batches, the consistency is strong and deviations are not easy to occur. The laser tracking device 101 can be used to monitor various parameters in the welding or cutting process, such as temperature, pressure, position, etc., and feed back the monitored data to the control system in real time. The control system adjusts the welding and cutting parameters according to the feedback information to ensure the processing quality.

[0036] Air inlet holes are drilled at the lower end and the left and right ends of the horizontal suspension beam 2. A flue gas purification device is installed in the horizontal suspension beam 2. When flue gas is generated by cutting, the flue gas purification device can start to absorb the flue gas and purify the flue gas, and then discharge it after purification, thereby effectively maintaining a good air environment in the factory. The flue gas purification device is a prior art and is not a protection point of this scheme, so it will not be elaborated here.

[0037] like Figure 4 The welding unit 5 includes a moving motor 51 slidably connected to the cross suspension beam 2, a fixed screw rod connected to the rotating end of the moving motor 51, a three-axis mechanical arm 52 threadedly connected to the fixed screw rod, and a welding assembly 53 installed at the end of the three-axis mechanical arm 52. The setting of the welding unit 5 enables the cutting robot to also have a welding function.

[0038] There is only one operating end of the cutting gun unit 6. The cutting gun unit 6 has a similar structure to the welding unit 5 and also includes a motor 51 and a three-axis robotic arm 52. A cutting gun assembly 64 is installed at the end of the three-axis robotic arm 52 on the cutting gun unit 6. Through the setting of the three-axis robotic arm 52, the cutting gun assembly 64 has 360° rotation freedom, which facilitates the cutting of profiles or plates.

[0039] The supporting rotary unit includes a top plate fixedly connected to the top of the column 1, a bearing plate 21 located above the top plate, and a rotary assembly installed between the top plate and the bearing plate 21. The bearing plate 21 is fixedly connected to the horizontal suspension beam 2. A triangular rib plate is also installed on the upper end of the bearing plate 21 and the outer end of the horizontal suspension beam 2. The rotary assembly includes a rotary motor 71 fixedly installed at the lower end of the top plate, a follower gear plate 73 coaxially arranged with the column 1, and an active gear plate 72 meshingly connected with the follower gear plate 73. The rotating end of the rotary motor 71 movably passes through the top plate and is fixedly connected to the middle part of the active gear plate 72. The upper end of the shaft of the follower gear plate 73 is fixedly connected to the bearing plate 21, and the lower end of the shaft of the follower gear plate 73 is connected to the top plate. The plate is rotated and connected. When it is necessary to switch the workstation, the rotary motor 71 is controlled to start, so that the active gear plate 72 rotates, and then drives the follower gear plate 73 to rotate, so that the cross suspension beam 2 connected to the follower gear plate 73 rotates accordingly, so as to realize the position switching of the welding unit 5 and the cutting gun unit 6 in the profile tooling and the profile tooling. Compared with the two sets of cutting equipment for profiles and plates in the prior art, this solution effectively saves the number of equipment, reduces the floor space demand of the workshop, and effectively reduces the processing cost. Compared with the method of constantly replacing the profile tooling and the plate tooling with one set of equipment, the workload, difficulty and time consumed during switching are greatly reduced, thereby effectively ensuring the use efficiency.

[0040] In summary, by supporting the setting of the rotary unit, the horizontal suspension beam 2 equipped with the cutting gun unit 6 can switch the workstation, and thus can adapt to the cutting processing of profiles and plates at the same time. Compared with the existing technology, the application scope of the cutting robot is improved, and some equipment settings are effectively saved, thereby reducing processing costs.

[0041] The second implementation method:

[0042] Based on the first embodiment, this embodiment changes the number of operating ends of the cutting gun unit 6, replaces the welding unit 5 in the first embodiment, and replaces it with a cutting gun unit 6 with only one operating end, so as to achieve multiple simultaneous cutting operations and improve the cutting efficiency of profiles or plates. The rest of the parts remain consistent with the first embodiment.

[0043] Figure 5-6As shown, the operating end of the cutting gun unit 6 is arranged in multiple, and the cutting gun unit 6 includes two fixed motors 61 fixedly connected to the outer end of the horizontal suspension beam 2, a moving screw connected to the rotating end of the fixed motor 61, a slideway 62 located between the two fixed motors 61, and multiple sliding blocks 63 connected to the outside of the slideway 62 through an electric slide. The lower ends of the multiple sliding blocks 63 are also installed with cutting gun assemblies 64. The two ends of the slideway 62 are respectively threadedly connected to the moving screws on the two fixed motors 61. Through the cooperation of the fixed motor 61 and the screw, the slideway 62 can move up and down along the screw. The arrangement of multiple cutting gun assemblies 64 enables multiple cutting gun assemblies 64 to work simultaneously as needed in this embodiment, thereby realizing multi-point cutting, thereby improving work efficiency.

[0044] The cutting gun assembly 64 in the cutting gun unit 6 with multiple operating ends adopts flame cutting, while the cutting gun unit 6 with a single operating end adopts laser cutting.

[0045] The third implementation method:

[0046] Based on the first embodiment, this embodiment changes the connection method between the bearing plate 21 and the suspension beam 2, and adds a real-time positioning unit and related contents. The rest of the parts are consistent with the first embodiment.

[0047] Figure 7 It is shown that the bearing plate 21 is slidably connected to the bottom of the suspension beam 2 through an electric slide, and the left and right ends of the suspension beam 2 are fixedly connected with real-time positioning units. The two real-time positioning units are respectively located in the middle of the suspension beam 2 and one end of the suspension beam 2 close to the column 1. An electromagnetic positioning plate 83 is fixedly embedded on the upper end of the bearing plate 21, and the electromagnetic positioning plate 83 matches the real-time positioning unit.

[0048] like Fig. 9 The instant positioning unit includes an upper positioning plate 81 fixedly connected to the cross suspension beam 2, a plurality of I-shaped positioning columns 821 movably penetrating the upper positioning plate 81, and a gasket 822 movably sleeved on the outer end of the neck of the I-shaped positioning column 821, the gasket 822 is located above the upper positioning plate 81, and the gasket 822 is an elastic structure. The electromagnetic positioning plate 83 includes a plurality of electromagnetic segments 831 corresponding to the plurality of I-shaped positioning columns 821, and a plurality of isolation segments 832 respectively fixedly connected between two adjacent electromagnetic segments 831. After the electromagnetic segment 831 is energized, there is a magnetic attraction between the corresponding I-shaped positioning column 821, and the isolation segment 832 is made of insulating material, such as Figure 7-8, c2 in the figure represents the rotation trajectory when the middle part of the horizontal suspension beam 2 is the rotation point. When it is necessary to switch the work station, the electromagnetic positioning plate 83 can be controlled to be powered off, so that the temporary fixation between the horizontal suspension beam 2 and the load-bearing plate 21 is released. At this time, the horizontal suspension beam 2 is controlled to move relative to the column 1 by the electric slide until the middle part of the horizontal suspension beam 2 moves above the load-bearing plate 21, so that the rotation point of the horizontal suspension beam 2 and the column 1 is switched from the end of the horizontal suspension beam 2 to the middle part of the horizontal suspension beam 2. At this time, the electromagnetic positioning plate 83 is controlled to be powered on, so that the electromagnetic positioning plate 83 temporarily absorbs the corresponding I-shaped positioning column 821, so that the horizontal suspension beam 2 and the load-bearing plate 21 are temporarily fixed, and then the support rotary unit is controlled to rotate, so that one end with the horizontal suspension beam 2 and the cutting gun unit 6 is rotated to another work station, and then according to actual needs, the rotation point of the horizontal suspension beam 2 and the column 1 is set at the middle or end for welding or cutting operations.

[0049] For example, when cutting a wider plate, the rotation point can be adjusted to the end of the cross beam 2. When cutting a smaller profile, the rotation point can be adjusted to the middle of the cross beam 2. Therefore, the space occupied by the cutting robot due to rotation will not be too large during use.

[0050] It is worth noting that in order to ensure stability during cutting and welding, the electromagnetic positioning plate 83 is kept powered on during welding or cutting to lock the cross suspension beam 2 and the bearing plate 21 .

[0051] When the electromagnetic positioning plate 83 is not energized, the distance between the lower end of the I-shaped positioning column 821 and the electromagnetic positioning plate 83 is less than the thickness of the gasket 822, so that the lower end of the I-shaped positioning column 821 does not contact the electromagnetic positioning plate 83 at this time, so that when the cross suspension beam 2 moves horizontally at the upper end of the column 1, the electromagnetic positioning plate 83 is not easy to block its movement. After the electromagnetic positioning plate 83 is energized, it absorbs the I-shaped positioning column 821 and connects them as a whole, so that the load-bearing plate 21 and the cross suspension beam 2 are in a relatively fixed state, so that when rotating, or when the welding unit 5 and the cutting gun unit 6 are working, the lateral relative position of the cross suspension beam 2 and the load-bearing plate 21 is not easy to change, effectively ensuring the stability of the cutting robot during rotation, welding and cutting. In addition, when the electromagnetic positioning plate 83 absorbs the I-shaped positioning column 821, the gasket 822 can be squeezed to be compressed, so that the gasket 822 is not easy to affect the temporary fixation between the load-bearing plate 21 and the cross suspension beam 2.

[0052] See also Figure 10-11 A tilt monitoring unit 9 is also provided at the lower end of one of the real-time positioning units. The tilt monitoring unit 9 includes two follower columns 91 fixedly connected to the lower end of the upper positioning plate 81, a ball restraining tube 92 fixedly connected between the two follower columns 91, and a steel ball 93 placed in the ball restraining tube 92. The ball restraining tube 92 and the upper positioning plate 81 are parallel to the horizontal suspension beam 2.

[0053] like Fig.12 The follower column 91 includes a shaping tube 911 fixedly connected to the lower end of the upper positioning plate 81, a follower hemisphere 912 fixedly connected to the lower end of the shaping tube 911, and a sensing hemisphere 913 fixedly connected to the end of the shaping tube 911 facing the ball-binding tube 92. The sensing hemisphere 913, the follower hemisphere 912, and the shaping tube 911 are interconnected, and the interiors of the three are saturated with water. The sensing hemisphere 913 and the follower hemisphere 912 are both made of elastic sealing materials, and the sensing hemisphere 913 is located in the ball-binding tube 92. An infrared rangefinder 901 is installed on the top of the shaping tube 911, and the transmitting end of the infrared rangefinder 901 is facing the middle of the follower hemisphere 912. The inner wall of the shaping tube 911 is also fixedly connected to a light-transmitting plate 902, and the light-transmitting plate 902 is higher than the ball-binding tube 92. Fig.13 When the horizontal suspension beam 2 tilts abnormally, the tilt monitoring unit 9 parallel to it tilts accordingly, causing the steel ball 93 to move toward the sinking side, squeezing the corresponding side sensing hemisphere 913, causing water to enter the follower column 91, and causing the follower hemisphere 912 to expand outward under the water pressure, so that the data of the corresponding infrared rangefinder 901 is significantly increased at this time, realizing the conversion of the slight and difficult-to-detect lateral deviation of the horizontal suspension beam 2 into an easily monitored change in the vertical direction, so that the potential safety hazards caused by the tilt of the horizontal suspension beam 2 can be discovered in time, so that timely maintenance can be carried out, effectively ensuring safe production in the factory.

[0054] And when its tilt is detected, the control box 4 can control the movement of the suspension beam 2 to adjust the rotation point to the middle, thereby improving the overall balance of the suspension beam 2, and at the same time control the magnetic attraction force of the electromagnetic section 831 on the tilted side to increase, thereby making the stability between the suspension beam 2 and the column 1 stronger, and then wait for maintenance to further reduce safety hazards.

[0055] The lower end of the follower column 91 does not contact the electromagnetic positioning plate 83, so that the electromagnetic positioning plate 83 is not easy to limit the deformation of the lower end of the follower column 91 after tilting.

[0056] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
