Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a multi-station flexible industrial welding equipment for construction engineering. Background Technology

[0002] In the manufacturing industry, welding is one of the most common ways to connect workpieces. When welding workpieces, they need to be positioned in advance. Due to the large differences in the shape of different workpieces, on-site workers need to do a lot of teaching work on the workpiece cutting, assembly, and clamping position deviations, which is extremely inconvenient. In addition, existing welding operations often require manual operation by workers, and the welding process generates a lot of heat, radiation, and toxic gases, which can cause significant harm to the workers' health. Therefore, using welding robots to complete welding work is the future trend of the welding industry.

[0003] Flexible welding robot systems organically combine industrial robot technology and flexible manufacturing, effectively reducing the number and skill requirements of on-site personnel. This not only saves companies on product process development, equipment procurement, and operating costs, significantly improving product quality and production efficiency, but also minimizes the harm welding causes to workers. Compared to traditional manual welding, flexible welding robots are transforming product processing towards full automation, high flexibility, and intelligence.

[0004] In traditional multi-station flexible industrial welding equipment, the robotic arm is mostly installed on one side of the material support platform. During the welding process, the robotic arm carries the welding head to perform flexible welding on the material nodes. Various factors, such as the installation position of the support platform, the angle and height of the support platform after fixing the material, and the position of the welding point, may increase the mechanical movement of the robotic arm when carrying the welding head. This causes the robotic arm to frequently change the angle and height of the welding head for different material nodes, thereby increasing the power work of the robotic arm, increasing the probability of damage to the robotic arm, and reducing the service life of the robotic arm under normal use. To address this, a multi-station flexible industrial welding equipment for building engineering is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station flexible industrial welding equipment for construction engineering, so as to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The structure of this device solves the problem of the robotic arm being overloaded and frequently working during the welding process of the frame edge welding robot in the traditional welding process, which may affect the normal service life of the robotic arm, reduces the probability of damage, and improves the efficiency and welding accuracy of the device. 2. The multi-structure design not only stabilizes the frame in its upright state, but also buffers the impact force when the welding head comes into contact with the frame welding node during the subsequent welding process, thereby improving the welding quality and the welding efficiency of the device. 3. By adding a cleaning mechanism and a buffer mechanism to the device, welding slag can be cleaned in real time to ensure that the welding platform is clean and tidy. At the same time, the buffer mechanism is filled with pseudo-plastic fluid between the return spring and the expansion diaphragm to deal with the abnormal state of the frame falling. If the latex airbag is compressed too much, the gas will impact the cleaning mechanism and cause damage to the cleaning mechanism. The pseudo-plastic fluid will solidify under the momentary violent impact, thereby assisting the return spring to further buffer such abnormal impacts. Attached Figure Description

[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 to 10 The present invention provides a technical solution: A multi-station flexible industrial welding equipment for construction engineering includes a welding platform 1. Fixing seats 12 are symmetrically fixed on the front and rear sides of the upper outer surface of the welding platform 1. A welding robot body 11 is provided on the left side of each fixing seat 12. Clamping mechanisms 2 are provided on the adjacent surfaces of the two fixing seats 12. A frame 13 is clamped and fixed by the two sets of clamping mechanisms 2. A support mechanism 4 is provided at the corresponding position of the central axis of the two fixing seats 12. The clamping mechanism 2 includes a servo motor 21, a fixed disk 22, a rotating groove 221, a clamping groove 23, a transmission rod 24, a roller 241, a base 242, a bearing 243, a magnet 244, a threaded part 245, a clamping plate 25, a clamping block 26, a limiting block 261, and a connecting block 262. The fixed disk 22 is positioned at the center of the front outer surface of the fixed base 12, and a drive motor 14 is positioned inside the fixed base 12 corresponding to the fixed disk 22. The output end of the drive motor 14 is fixedly connected to the center of the fixed disk 22. The upper end of the annular side of the fixed disk 22 is a smooth surface where the servo motor 21 is fixedly mounted. The center of the interior of the fixed disk 22 is... A rotating groove 221 is formed at the corresponding position of the output shaft of the servo motor 21, and a transmission rod 24 is rotatably connected inside the rotating groove 221. The upper end of the transmission rod 24 is fixedly connected to the output shaft of the servo motor 21, and a base 242 is provided at its lower end. A bearing 243 is embedded in the upper end of the base 242, and the bottom end of the transmission rod 24 is fixed to the inner ring of the bearing 243, thereby realizing the rotatable connection of the base 242. A transverse clamping groove 23 is formed on the outer surface of the front end of the fixed disk 22, and the clamping groove 23 communicates with the rotating groove 221. Clamping plates 25 are provided on both the upper and lower sides of the inner surface of the clamping groove 23. The clamping plates 25 are made of arc-shaped elastic metal, and their two ends are respectively connected to the clamping groove 23. The clamping plate 25 is fixed with an anti-slip rubber sleeve on its outer surface. Three rollers 241 are fixedly fitted onto the outer surface of the transmission rod 24 within the clamping groove 23 area. The three rollers 241 have identical structures and are evenly distributed. A magnet 244 is embedded at the center of the annular side of each roller 241. The outer surface of the magnet 244 is horizontally aligned with the annular side of the roller 241. A threaded portion 245 is provided on the outer surface of the transmission rod 24, centered on the roller 241, with the thread directions of the upper and lower threads of the transmission rod 245 being opposite. The clamping groove 23 has symmetrically formed movable grooves 34 on its upper and lower sides, corresponding to the positions of the rotating groove 221. The movable grooves 34 are aligned with the rotating groove 221. The clamping groove 23 is symmetrically arranged with clamping blocks 26 on both the upper and lower sides. The rear center position of the clamping block 26 is fixedly connected to the limiting block 261, and the rear end of the limiting block 261 is fixedly connected to the connecting block 262. The connecting block 262 is distributed in a ring structure and is threadedly connected to the upper threaded part 245 on the outer surface of the transmission rod 24. That is, when the transmission rod 24 rotates clockwise, the clamping block 26 moves downward through the threaded connection between the limiting block 261 and the connecting block 262. When it rotates counterclockwise, it rises. The length of the movable groove 34 is greater than the length of the threaded part 245. The clamping blocks 26 on both the upper and lower sides of the front outer surface of the fixed disk 22 have the same structure. The limiting block 261 is provided with a limiting mechanism 3 on its surface.

[0019] The support mechanism 4 includes an elastic clamping block 41, a first U-shaped plate 42, a second U-shaped plate 43, a pressing block 44, a first inflatable airbag 45, a gas conduit 46, a second inflatable airbag 47, and a column 48. The elastic clamping block 41 has a U-shaped structure and is made of hard rubber. The first U-shaped plate 42 is arranged inside the elastic clamping block 41, and the second U-shaped plate 43 is arranged inside the first U-shaped plate 42. The two ends of the second U-shaped plate 43 are fixedly connected to the middle of the first U-shaped plate 42. The first inflatable airbag 45 is glued between the first U-shaped plate 42 and the second U-shaped plate 43. The bottom end of the clamping block 26 passes through the pressing block 44, and the bottom end of the pressing block 44 is connected to... The second U-shaped plate 43 is fixedly connected. The lower end of the first inflatable airbag 45 is provided with an air pipe. The air pipe passes through the first U-shaped plate 42 and is connected to a gas conduit 46. The other end of the gas conduit 46 is connected to the second inflatable airbag 47. There are six second inflatable airbags 47. They are arranged in a semi-circular structure, with three in a group symmetrically distributed on the inner surface of the U-shaped elastic clamping block 41. The three second inflatable airbags 47 are interconnected. The lower outer surface of the elastic clamping block 41 is fixedly connected to a column 48. The number of support mechanisms 4 is three groups that are equidistantly distributed on the upper outer surface of the welding platform 1 at the center axis position of two groups of fixed seats 12. The lower end of the support mechanism 4 is provided with a buffer mechanism 6.

[0020] As an embodiment of the present invention, the limiting mechanism 3 includes a first spring 31, a second spring 32, a guide post 33, and a movable groove 34. The second spring 32 is provided on the upper side of the limiting block 261, and the first spring 31 is provided on its lower side. The two ends of the first spring 31 and the second spring 32 are respectively fixedly connected to the upper and lower ends of the inner wall of the limiting block 261 and the movable groove 34. The guide post 33 is movably connected through the inner center of the limiting block 261, and both the first spring 31 and the second spring 32 are sleeved on the outer surface of the guide post 33.

[0021] During operation, it is important to note that the roller 241 needs to rotate continuously for a certain number of revolutions to achieve the required translational distance of the frame 13. Therefore, the connecting blocks 262 corresponding to the clamping blocks 26 on the upper and lower sides cannot continuously be connected to the transmission rod 24 by thread. The length of the threaded portion 245 is designed to allow the connecting block 262 to disengage from the threaded portion 245 during over-range rotation, thereby avoiding affecting the rotation of the transmission rod 24. At the same time, during the process of the clamping block 26 disengaging from the corresponding threaded portion 245, the first spring 31 and the second spring 32 are compressed by the limiting mechanism 3 to keep the connecting block 262 always tight. The threaded part 245 disengages from the edge. When it needs to be clamped again, the transmission rod 24 rotates clockwise. At this time, under the tension of the first spring 31 and the second spring 32, the connecting block 262 can instantly contact and connect with the threaded part 245, displacing the limiting block 261 and its corresponding clamping block 26. It is worth noting that because the displacement of the clamping block 26 requires the transmission rod 24 to rotate a certain number of times, the roller 241 also drives the frame 13 to translate in real time. Therefore, in subsequent operations, the frame 13 needs to be translated beyond the range first, and then translated in the opposite direction to the specified position during the clamping process.

[0022] In one embodiment of the present invention, the buffer mechanism 6 includes a fixed plate 61, a buffer block 62, a movable cavity 63, and a latex airbag 64. The upper outer surface of the welding platform 1 is fixedly connected to the strip fixed plate 61 at the corresponding position of the support mechanism 4. Three columns 48 and elastic clamping blocks 41 are equidistantly distributed on the upper end of the fixed plate 61. The movable cavity 63 is opened inside the fixed plate 61 at the corresponding position of the columns 48. The movable cavity 63 and the columns 48 are distributed in a T-shape and movably connected. The lower end of the columns 48 is glued to the upper end of the latex airbag 64. The latex airbag 64 is distributed in a U-shape and its lower end is fixed to the inner wall of the movable cavity 63.

[0023] During operation, each time the frame 13 is erected and placed on the support mechanism 4, the column 48 in the support mechanism 4 moves downward inside the movable cavity 63 in the buffer mechanism 6, thereby compressing the latex airbag 64, the expansion membrane 67, and the return spring 65 downward. This series of actions is used to deal with the vibration during the erection of the frame 13 or the irregular impact during the welding process. The design of the buffer block 62 is used to deal with the collision under slight displacement.

[0024] In one embodiment of the present invention, the latex airbag 64 is provided with a cylindrical expansion membrane 67 with a tapered longitudinal section, and a return spring 65 is provided inside the expansion membrane 67. The two ends of the return spring 65 are fixed with rubber pads and are fixedly connected to the inner surface of the expansion membrane 67 and the inner wall of the movable cavity 63 through the rubber pads. The top end of the expansion membrane 67 is bonded to the latex airbag 64. The two ends of the latex airbag 64 are fixedly connected with air supply pipes 66, and the air supply pipes 66 extend to the outside of the fixing plate 61.

[0025] During operation, a pseudo-plastic fluid is injected between the return spring 65 and the expansion membrane 67 inside the buffer mechanism 6 to cope with the abnormal fall of the frame 13. This causes the latex airbag 64 to compress significantly, resulting in gas impacting the cleaning mechanism 5 and causing damage to the cleaning mechanism 5. The pseudo-plastic fluid will solidify under the momentary violent impact, thereby assisting the return spring 65 to further buffer such abnormal impacts. During the compression process of the buffer mechanism 6, it provides a power source for the cleaning mechanism 5. Through the mutual cooperation of the two mechanisms, the cleaning of welding slag and the buffering and shock absorption are achieved.

[0026] As an embodiment of the present invention, a buffer mechanism 6 is provided at the bottom of each of the three support mechanisms 4, and the length of the column 48 in the support mechanism 4 located in the middle of the fixed plate 61 is greater than the height of the column 48 in the support mechanisms 4 on the front and rear sides, and the volume of the latex airbag 64 in the corresponding buffer mechanism 6 is also greater than that of the two groups in front and rear. Cleaning mechanisms 5 are symmetrically provided on both sides of the fixed plate 61.

[0027] During operation, when the frame 13 is vertically lowered, due to the material of the support mechanism 4, the opening angle of the elastic clamp 41 is prone to deviation after long-term use. This results in the frame 13 being able to connect with only one or two sets of support mechanisms 4 when vertically lowered, and the additional support mechanisms 4 being misaligned. To solve this problem, the height of the intermediate support mechanism 4 and the capacity of the corresponding latex airbag 64 are changed. The latex airbag 64 in the intermediate support mechanism 4 is connected to the latex airbags 64 of the two sets of corresponding support mechanisms 4 in front and behind through pipes. During the downward movement of the frame 13, it first initially contacts the intermediate support mechanism 4 and moves downward to compress the latex airbag 64 in the corresponding buffer mechanism 6. At this time, the gas inside the latex airbag 64 in the intermediate position will be compressed and transported to the other two sets. The latex airbags 64 of the other two sets will expand and rise to press against the column 48, forcing the other two sets of support mechanisms 4 to actively move upward to clamp the edge of the frame 13. Then, they slowly move downward together to do work on the cleaning mechanism 5.

[0028] In one embodiment of the present invention, the cleaning mechanism 5 includes a guide plate 51, a displacement groove 52, a slider 53, a threaded airbag 54, a tension spring 55, and a telescopic assembly 56. Guide plates 51 are symmetrically fixed to both sides of the fixed plate 61, front and back. A cleaning plate 57 is disposed between the guide plates 51. The displacement groove 52 is formed inside the guide plate 51, and the slider 53 and the threaded airbag 54 are disposed inside the displacement groove 52. One end of the slider 53 is glued to one end of the threaded airbag 54, and the other end of the slider 53 is attached to one end of the cleaning plate 57. The threaded airbag 54 is fixedly connected to the inner wall of the displacement groove 52 by adhesive bonding. The threaded airbag 54 is provided with a telescopic component 56 inside, and both ends of the telescopic component 56 are fixed parallel to the threaded airbag 54. The outer surface of the telescopic component 56 is fitted with a tension spring 55, and both ends of the tension spring 55 are fixed to the ends of the telescopic component 56. The telescopic component 56 is made up of several sleeves of different diameters that are matched with each other and cannot be disengaged and are inserted and connected. One end of the air supply pipe 66 extends into the interior of the threaded airbag 54.

[0029] During operation, the cleaning mechanism 5 works in conjunction with the support mechanism 4. Each time the frame 13 is erected and placed on the support mechanism 4, the column 48 in the support mechanism 4 moves downward inside the movable cavity 63 in the buffer mechanism 6, thereby compressing the latex airbag 64, the expansion membrane 67, and the return spring 65 downward. This series of actions not only helps to deal with the vibration during the erection of the frame 13, but also the compressed gas in the latex airbag 64 is delivered to the threaded airbag 54 in the displacement groove 52 inside the guide plate 51. The expansion and extension of the threaded airbag 54 drives the slider 53 to move in the displacement groove 52, thus driving the cleaning plate 57 connected to the slider 53. The cleaning brush glued to the lower end of the cleaning plate 57 pushes and cleans the welding slag that has fallen on the welding platform 1. After the frame 13 is separated from the support mechanism 4, the gas inside the threaded airbag 54 flows back, the tension spring 55 stretches the telescopic component 56 to reset, and the cleaning plate 57 is pulled back for the next push to clean the welding slag, thereby achieving real-time cleaning of welding slag and ensuring that the welding platform 1 is clean and tidy.

[0030] Working principle: By adding a clamping mechanism 2 to the device, the worker initially assembles the frame 13 by inserting it in the early stage of welding and aligns the two sides of the frame 13 with the clamping grooves 23 on the surface of the fixed plate 22 in the clamping mechanism 2. Since the openings on both sides of the clamping grooves 23 are arc-shaped expansion type, it is easy for the user to easily insert the two sides of the frame 13 into the clamping grooves 23. During the insertion process, the edge of the frame 13 contacts the clamping plate 25 and squeezes the arc-shaped elastic metal clamping plate 25. The clamping plate 25 achieves the purpose of initially fixing the frame 13. Then the frame 13 is initially fixed on the clamping mechanism 2. The worker moves away from the welding platform 1. At this time, the servo motor 21 is controlled to rotate clockwise. The rotation is transmitted through the transmission power, that is, the threaded part 245 with the opposite thread on the outer surface of the transmission rod 24 connects with the connecting block. The 262 threaded connection controls the displacement of the limit block 261 within the movable groove 34. At this time, the upper and lower clamping plates 25 move towards each other, clamping and fixing the edge of the frame 13, thus stabilizing the frame 13 during clamping. This ensures stability and accuracy of the welding joints during subsequent welding of the frame 13 by the welding robot body 11, preventing incomplete welds. Since the welding robot body 11 is mounted on one side of the fixed base 12, the side of the frame 13 furthest from the welding robot is often far from the welding head of the welding robot body 11 during welding. Therefore, the welding robot often needs to frequently rotate and adjust the angle of its welding arm during welding, which increases the workload of the welding robot body and affects its normal operation. To extend the service life, when welding is required at the other side of the frame 13, the servo motor 21 rotates counterclockwise, and the clamping block 26 rises in the opposite direction. At this time, the frame 13 loses its fastening state and is initially fixed by the clamping plate 25. At the same time, the roller 241 rotates under the action of the transmission rod 24 and is attracted and attached by the magnet 244 to drive the frame 13 to move inside the clamping groove 23 in the fixed plate 22, thus moving the position of the frame 13. This allows the welding robot to weld the edge welding nodes of the frame 13 better and more conveniently. It should be noted that the roller 241 needs to rotate continuously for a certain number of revolutions to achieve the required translation distance of the frame 13. Therefore, the connecting blocks 262 corresponding to the clamping blocks 26 on the upper and lower sides cannot continuously connect with the threads of the transmission rod 24. The length of the threaded portion 245 is designed to allow the connecting block 262 to disengage from the threaded portion 245 during over-range rotation, thus avoiding affecting the rotation of the transmission rod 24. Simultaneously, during the disengagement of the clamping block 26 from the corresponding threaded portion 245, the first spring 31 and the second spring 32 in the limiting mechanism 3 are compressed, ensuring that the connecting block 262 remains close to the disengagement edge of the threaded portion 245. When re-clamping is required, the transmission rod 24 rotates clockwise. At this time, under the tension of the first spring 31 and the second spring 32, the connecting block 262 can instantly contact and thread-connect with the threaded portion 245, displacing the limiting block 261 and its corresponding clamping block 26. It is worth noting that the displacement of the clamping block 26 requires the transmission rod 24 to rotate a certain number of times.Therefore, roller 241 also drives the frame 13 to translate in real time. Thus, in subsequent operations, to translate the frame 13 a specified distance, it needs to first translate beyond the range, and then reverse and translate to the specified position during clamping. This device structure solves the problem of excessive and frequent overload work on the robotic arm during welding of the frame 13 edge position in traditional welding processes, which may affect the normal service life of the robotic arm, reducing the probability of damage and improving the efficiency and welding accuracy of the device. By adding a support mechanism 4 to this device, welding is required on both the front and back nodes of the frame 13 during the welding process. Therefore, by controlling the clamping mechanism 2 through the drive motor 14, 360-degree rotation adjustment of the frame 13 can be achieved. Meanwhile, the welding of the frame 13 is not always kept flat. In the case of welding in the horizontal state, the frame 13 may need to be erected during welding of special areas. During this process, due to the weight of the frame 13 itself and the impact of the welding head on the frame 13, slight slippage of the frame 13 within the clamping mechanism 2 is possible. Such displacement during welding significantly affects the welding quality, resulting in defective products. Therefore, to address this issue, a support mechanism 4 was designed based on the original clamping mechanism 2. In use, the drive motor 14 controls the clamping mechanism 2 to rotate and erect the frame 13. Then, the servo motor 21 operates, the fastening is disabled, and the frame 13 slides down under its own weight until its edge is inserted into the corresponding U-shaped support mechanism 4 below. Inside the elastic clamp 41, the frame 13 is initially fixed in its upright position. Then, under its own weight, the frame 13 continues to press down, squeezing the pressing block 44. At this point, the elastic clamp 41, under the combined action of the first U-shaped plate 42 and the second U-shaped plate 43, causes the U-shaped elastic clamp 41 to close tightly, securing the edge of the frame 13, achieving secondary fixation. Then, the deformation of the first U-shaped plate 42 and the second U-shaped plate 43 also compresses the first expansion airbag 45 between them, causing the compressed gas inside to enter the second expansion airbag 47 through the gas conduit 46. The expansion of the second expansion airbag 47 further fixes the edge of the frame 13, achieving a third fixation. This multi-structure design not only stabilizes the frame 13 in its upright position... Furthermore, this structure, when used in conjunction with the welding head, can buffer the impact force when the welding head contacts the welding node of the frame 13 during subsequent welding processes, thereby improving welding quality and the welding efficiency of the device. By adding the cleaning mechanism 5 and the buffer mechanism 6 to this device, the generation of welding slag, a problem that is difficult to solve in traditional welding processes, is addressed. The generation of welding slag requires considerable manual time for cleaning, thus ensuring a safe welding environment and preventing interference with the normal operation of the welding equipment. Therefore, to solve a series of problems in traditional welding processes, such as workers entering the machine operation area, increasing the probability of personal injury, poor manual handling efficiency, and high labor costs, the cleaning mechanism 5 is used in conjunction with the support mechanism 4. During each time the frame 13 is erected and placed on the support mechanism 4...The column 48 in the support mechanism 4 moves downward inside the movable cavity 63 in the buffer mechanism 6, thereby compressing the latex airbag 64, the expansion membrane 67, and the return spring 65 downward. This series of actions not only helps to withstand the vibration during the vertical placement of the frame 13, but also the compressed gas in the latex airbag 64 is delivered to the threaded airbag 54 in the displacement groove 52 inside the guide plate 51. The expansion and extension of the threaded airbag 54 drives the slider 53 to move in the displacement groove 52, thus driving the cleaning plate 57 connected to the slider 53. The cleaning brush glued to the lower end of the cleaning plate 57 pushes and cleans the welding slag that has fallen on the welding platform 1, and the frame 13 is detached. After leaving the support mechanism 4, the gas inside the threaded airbag 54 flows back, the tension spring 55 stretches the telescopic component 56 to reset, and the cleaning plate 57 is pulled back for the next push to clean welding slag, thus achieving real-time cleaning of welding slag to ensure the cleanliness of the welding platform 1. Simultaneously, the buffer mechanism 6 contains a pseudo-plastic fluid between the reset spring 65 and the expansion membrane 67 to cope with abnormal falls of the frame 13. This can cause the latex airbag 64 to compress excessively, resulting in gas impacting the cleaning mechanism 5 and causing damage. The pseudo-plastic fluid solidifies under the instantaneous violent impact, thus assisting the reset spring 65 in further buffering such abnormal impacts.
