Description

Technical Field

[0001] The present invention relates to the technical field of plate welding, and in particular to an automatic welding device for lifting elevator plates. Background Art

[0002] In the production process of elevator plates, welding is the key link in connecting and fixing the plates, which is directly related to the performance and safety of the final product. Traditional welding methods mainly rely on the skills and experience of operators, which not only increases production costs, but may also lead to unstable welding quality due to human factors.

[0003] Traditional welding methods usually rely on manual adjustment of welding parameters, such as current and voltage. This method is not only inefficient, but also greatly affected by human operation, which can easily lead to inaccurate welding parameter settings, thereby affecting welding quality. In particular, when the thickness of the plate is uneven or varies greatly, it is difficult to achieve adaptive adjustment of the welding parameters, which can easily lead to welding defects. In addition, traditional welding equipment often lacks automation functions and requires manual operations such as clamping, positioning, and flipping the plate. This not only increases labor intensity and reduces production efficiency, but is also easily affected by human factors, resulting in unstable welding quality. In addition, a large amount of harmful gases and impurities are generated during the welding process, posing a threat to the working environment and the health of operators. Existing welding equipment often lacks effective purification measures and cannot effectively reduce welding pollution, affecting the safety and hygiene of the working environment. Traditional welding equipment is often only suitable for plates of specific sizes and shapes. Different specifications and types of plates require the replacement of different fixtures or adjustment of the equipment structure, reducing the applicability and flexibility of the equipment.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In a typical implementation of this application, please refer to Figures 1 to 10 As shown, an automatic welding device for lifting elevator plates includes: two support legs 1, a workbench 2 is fixedly mounted on the top surface of the two support legs 1, baffles 3 are fixedly mounted at both ends of the top surface of the workbench 2, a controller 4 is fixedly mounted on one of the baffles 3, a distribution box 5 is fixedly mounted on the side wall of the right support leg 1, support blocks 6 are fixedly mounted on the top surfaces of the two baffles 3, and first support plates 7 are fixedly mounted on the top surfaces of the two support blocks 6;

[0031] The welding mechanism is arranged on the first support plate 7 and is located below the moving part. The welding mechanism includes:

[0032] A first robotic arm 8 is provided below the first support plate 7. A welding head 9 is fixedly mounted on the end of the first robotic arm 8. A laser sensor 10 is fixedly mounted on the top surface of the welding head 9. A suction pipe 11 is fixedly mounted on the bottom surface of the welding head 9. A through pipe 12 is provided on one side of the suction pipe 11. A fan 14 is fixedly mounted inside the suction pipe 11 through a support frame 13. The welding mechanism also includes a data processing and transmission component and a purification component.

[0033] A rotary clamping mechanism is provided between the two baffles 3 and is used to automatically clamp and flip the plate;

[0034] A moving member is provided on the first support plate 7 and is used to drive the first robotic arm 8 to move. The moving member includes: a first threaded rod 32, the first threaded rod 32 is provided on the first support plate 7, a sliding groove 33 is provided on the top surface of the first support plate 7, the first threaded rod 32 is rotatably connected to the inner wall of the sliding groove 33, a sliding block 34 is threadedly connected to the first threaded rod 32, the sliding block 34 slides on the sliding groove 33, the bottom surface of the sliding block 34 is connected to the top surface of the first robotic arm 8, a first motor 35 is fixedly installed on the side wall of the first support plate 7, and the output shaft of the first motor 35 is connected to one end of the first threaded rod 32;

[0035] Through the above-mentioned features, the first robotic arm 8 can be driven to move. Specifically, the staff turns on the first motor 35 through the controller 4, and the output shaft of the first motor 35 drives the first threaded rod 32 to rotate, so that the sliding block 34 connected to the first threaded rod 32 moves on the sliding groove 33. When the sliding block 34 moves, the first robotic arm 8 connected to the sliding block 34 will move synchronously, and the first threaded rod 32 has the function of forward rotation and reverse rotation.

[0036] As a preferred implementation in this embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 As shown, the data processing and transmission component includes: a receiver 15, which is fixedly mounted on the side wall of the baffle 3, a protective shell 16 is fixedly mounted on one side of the receiver 15, and a signal processing circuit 17 and a signal transmission circuit 18 are fixedly mounted on the side wall of the baffle 3, respectively, and the signal processing circuit 17 and the signal transmission circuit 18 are both located inside the protective shell 16;

[0037] Through the above-mentioned features, the working current of the welding head 9 can be automatically adjusted according to the different thicknesses of the two plates during welding, so as to avoid the influence of excessive or insufficient current of the welding head 9 on the plates. For example, the plates are easily burned through: due to excessive current, the melting speed of the plates is too fast, which may cause the plates to be burned through and fail to form qualified welds; the quality of the weld is reduced: the height of the weld may be insufficient, and the ideal weld shape cannot be formed; weld defects: it is easy to produce defects such as undercut, tungsten inclusion, pores, thermal cracks, etc., which affect the physical properties of the weld; increased metal spatter: excessive current will cause increased metal spatter, which not only wastes materials, but also may cause pollution to the operating environment; unstable arc: excessive current will cause the arc to vibrate violently, affecting the welding quality and effect; material bending and deformation: excessive current will cause the surface of the plate to be locally affected by excessive heat, resulting in bending and deformation of the material, and losing its original shape and geometric dimensions; detached welding: local high temperature may cause the welding part to break or fail Complete separation causes the welding part to lose its original strength and contact. Too small an impact, for example, weak welding: too small a current will lead to weak welding, too narrow welds, and poor welding effects; insufficient fusion of the weld and the plate: insufficient fusion of the plate, prone to clamping, sand holes, etc., and insufficient fusion of the weld and the plate; incomplete penetration and cold cracks: too small a current and insufficient penetration depth can easily cause problems such as incomplete penetration and cold cracks, affecting welding quality, etc. Specifically, when the welding head 9 is working, the laser sensor 10 above the welding head 9 monitors the thickness of the two welding plates and transmits the detected data to the receiver 15. The data received by the receiver 15 is then output to the signal processing circuit 17 for processing. The data processed by the signal processing circuit 17 is then transmitted to the signal transmission circuit 18, and the signal transmission circuit 18 transmits it to the controller 4, so that the controller 4 automatically adjusts the first robotic arm 8, and the protective shell 16 protects the signal processing circuit 17 and the signal transmission circuit 18;

[0038] It is worth mentioning that the laser sensor 10 obtains thickness data at different positions on the plate through non-contact measurement. These data are usually output in the form of analog current and voltage signals or digital signals. The signal processing circuit 17 and the signal transmission circuit 18 analyze and process the signals output by the laser sensor 10 to obtain the specific thickness values ​​of each point on the plate. According to the range of variation of the plate thickness, the current range that needs to be adjusted is determined. According to the empirical formula or preset algorithm, the relationship between the welding current i and the plate thickness d is determined, such as i = k×d, where k is the welding coefficient. According to the real-time data of the plate thickness, the required welding current is dynamically calculated.

[0039] As a preferred implementation in this embodiment, please refer to Figure 5 、 Figure 7 and Figure 10As shown, the purification component includes: a box body 19, which is fixedly mounted on the side wall of one of the support blocks 6, and the interior of the box body 19 is sequentially provided with a primary filter plate 20, a HEPA filter plate 21, an activated carbon filter plate 22, a glass fiber filter plate 23 and a ceramic filter plate 24, a collection box 25 is fixedly mounted on the bottom surface of the box body 19, and the other end of the through pipe 12 passes through the side wall of the support block 6 and extends into the box body 19, the purification component also includes a disassembly component, which includes: a limiting column 26, which is fixedly mounted on the side wall of one of the support blocks 6, and a magnet 27 is fixedly mounted on the side wall of the support block 6 below the limiting column 26, and the magnet 27 cooperates with the collection box 25, and a fixing block 28 is fixedly mounted on the top surface of the box body 19, and a limiting hole 29 is provided on the side of the fixing block 28 facing the limiting column 26, and the limiting hole 29 and the limiting column 26 are socketed with each other;

[0040] Through the above-mentioned features, the harmful gases generated during welding can be absorbed and filtered to avoid affecting the surrounding staff. When the welding head 9 is working, the fan 14 on one side will be turned on synchronously to transport the harmful gases generated during the operation of the welding head 9 to the box body 19 through the through pipe 12. The harmful gases pass through the primary filter plate 20, the HEPA filter plate 21, the activated carbon filter plate 22, the glass fiber filter plate 23 and the ceramic filter plate 24 in turn, and then flow out through the flow holes on the box body 19. During the operation of the fan 14, small impurities generated during the welding of the welding head 9 can also flow into the collection box 25 through the through pipe 12 for collection. When the box body 19 needs to be replaced and cleaned, the staff only needs to use force to separate the limiting hole 29 and the limiting column 26 and the magnet 27 from the collection box 25. The collection box 25 is made of iron and can be adsorbed by the magnet 27, while the limiting column 26 and the limiting hole 29 can limit it to avoid displacement. The installation only needs to be reversed from the above steps.

[0041] As a preferred implementation in this embodiment, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, the rotary clamping mechanism includes: two groups of clamping members, wherein the left clamping member is fixedly installed between the two baffles 3, and the right clamping member is slidably connected between the two baffles 3. The two groups of clamping members are symmetrically arranged, and the clamping members include: a first clamping plate 36, the first clamping plate 36 is arranged between the two baffles 3, a movable groove 37 is opened on the side wall of the first clamping plate 36, and a second threaded rod 38 is rotatably connected to the inside of the movable groove 37, and a movable block 39 is threadedly connected to the second threaded rod 38. A first clamping plate 36 is fixedly installed on the top surface of the first clamping plate 36. The second motor 40 has an output shaft connected to one end of the second threaded rod 38. A connecting column 41 is fixedly installed on the side wall of the movable block 39. A third motor 42 is fixedly installed inside the connecting column 41. A rotating plate 43 is rotatably connected to one side of the connecting column 41. The output shaft of the third motor 42 is connected to the center of the rotating plate 43. A sliding groove 44 is provided on the side wall of the rotating plate 43. A first electric push rod 45 is fixedly installed on the top surface of the sliding groove 44. The output end of the first electric push rod 45 is connected to a slider 46. One end of the slider 46 The side is fixedly installed with an upper splint 47, and the side wall of the rotating plate 43 is fixedly installed with a lower splint 48 below the upper splint 47. The surface adjacent to the upper splint 47 and the lower splint 48 is provided with anti-slip grooves, and a cross groove 49 is provided on the top surface of the support leg 1. The rotating clamping mechanism also includes: a second electric push rod 50, the second electric push rod 50 is arranged inside the transverse cross groove 49, and the output end of the second electric push rod 50 is connected to a moving block 51. The top surface of the moving block 51 is connected to the bottom surface of the first clamping plate 36 on the left side, and the cross groove 49 is a longitudinal groove transfer A third threaded rod 52 is dynamically connected, and the third threaded rod 52 is provided with threads at both ends of opposite rotation directions. The threads at both ends of the third threaded rod 52 are respectively provided with connecting blocks 53. The top surfaces of the two connecting blocks 53 are fixedly mounted with second clamping plates 54. A fourth motor 55 is fixedly mounted on the rear side wall of the support leg 1. The output shaft of the fourth motor 55 is connected to one end of the third threaded rod 52. A second support plate 30 is fixedly mounted on the top surfaces of the two baffles 3, and a second robotic arm 31 is fixedly mounted on the top surface of the second support plate 30.

[0042] By means of the above features, the plates can be clamped and turned over. Specifically, the two plates are placed on the top surface of the support leg 1 in turn by the second robotic arm 31, and then the second electric push rod 50 and the fourth motor 55 are started synchronously, so that the first clamping plate 36 on the right side approaches the first clamping plate 36 on the left side. At this time, the two lower clamping plates 48 are both located in the cross slot 49, so that the two first clamping plates 36 clamp the left and right sides of the plate. When the fourth motor 55 is started, the third threaded rod 52 connected to the output shaft of the fourth motor 55 will rotate, so that the two connecting blocks 53 approach each other, and drive the second clamping plate 54 connected to the top surface of the connecting block 53 to clamp the front and back sides of the plate. When turning over is required, the fourth motor 55 will first reverse, so that the two The second clamping plates 54 move away from each other, canceling the clamping of the front and rear plates, and the first electric push rods 45 on the two rotating plates 43 will start synchronously, causing the upper clamping plate 47 to move down and clamp the plate between the upper clamping plate 47 and the lower clamping plate 48. After that, the second motors 40 on the top surfaces of the first clamping plates 36 on both sides rotate synchronously, causing the two rotating plates 43 to drive the plate to move upward. After moving to the appropriate position, the third motor 42 in the two connecting columns 41 will start, causing the rotating plate 43 to rotate one hundred and twenty degrees to flip the plate over. After that, the two second motors 40 will reverse again, causing the rotating plate 43 to move down, and the flipping can be completed for subsequent operations. After welding is completed, the second robotic arm 31 starts again to take out the welded plate and then put the plate to be welded back in.

[0043] Working principle:

[0044] During use, the staff starts the first motor 35 through the controller 4, so that the output shaft of the first motor 35 drives the first threaded rod 32 to rotate. The first threaded rod 32 is threadedly connected to the sliding block 34 and is located in the sliding groove 33, so that the sliding block 34 moves along the sliding groove 33. Since the sliding block 34 is connected to the top surface of the first mechanical arm 8, the first mechanical arm 8 moves accordingly to adjust the position of the welding head 9. The laser sensor 10 is fixed to the top of the welding head 9 to monitor the thickness of the plate in real time during the welding process and transmit the data to the receiver 15. After the signal processing circuit 17 and the signal transmission circuit 18 process the data, the information is transmitted to the controller 4, and the controller 4 automatically adjusts according to the data. The operating current of the welding head 9 is adjusted to match the thickness of the plate to prevent the welding quality from being affected by excessive or insufficient current. At the same time, the fan 14 is started when the welding head 9 is working, and the harmful gases generated by welding are transported to the box body 19 of the purification component through the suction pipe 11 and the through pipe 12. The gas is discharged after passing through the multi-stage filtration of the primary filter plate 20, the HEPA filter plate 21, the activated carbon filter plate 22, the glass fiber filter plate 23 and the ceramic filter plate 24, effectively purifying the harmful gases generated by welding. In addition, small impurities are collected in the collection box 25 through the through pipe 12. The rotary clamping mechanism realizes automatic clamping and flipping of the plate through the cooperation of the second electric push rod 50 and the fourth motor 55. Specifically, the second electric push rod 50 pushes the moving block 51, so that the first clamping plate 36 on the left side approaches the first clamping plate 36 on the right side, and cooperates with the lower clamping plate 48 to clamp the left and right sides of the plate. The fourth motor 55 rotates the third threaded rod 52, so that the connecting block 53 drives the second clamping plate 54 to clamp the front and back sides of the plate. When the plate needs to be turned over, the second motor 40 and the third motor 42 work together to make the rotating plate 43 turn over the plate, thereby completing the automatic turning operation.
