Description

Technical Field

[0001] The utility model relates to a robot welding platform. Background Art

[0002] Existing robotic welding platforms typically consist of a fixed frame and a rigid, porous support plate mounted on the frame, with a welding robot positioned on one side of the plate. These platforms are widely used, and modifications based on them are highly versatile.

[0003] Although the welding process in automobile production is highly automated, operators still need to work in close proximity to the welding platform. During the welding process, the large amount of smoke and dust generated by the welding equipment not only pollutes the production environment but also poses a threat to the health of workers.

[0004] For welding robots, the structure of the traditional fixed welding device is relatively fixed. The workpiece cannot be rotated after being fixed, and its flexibility is low. In addition, the range of motion of the welding robot is limited by the active radius and degree of freedom of the robotic arm. Therefore, during the welding process, it is necessary to frequently disassemble the workpiece, adjust the workpiece angle, or increase the number of robots to ensure that the workpiece is welded in place. However, such cumbersome operations make the welding efficiency low.

[0005] There are two main purification strategies currently used in welding workshops: the first involves installing a vertical suction hood above the welding platform; the second involves using fans throughout the entire workshop for ventilation. While effective, the first approach occupies a larger welding area, limiting the working radius of the welding robot. Furthermore, the high suction force required to remove large particles of settling pollutants can cause vibrations, which can affect welding accuracy. The second approach results in a long diffusion path for welding fumes and associated toxic substances, resulting in low emission efficiency and an increased risk of occupational illness. Utility Model Content

[0006] The technical problem to be solved by the utility model is that, in view of the deficiency of the current robot welding platform that the welding angle cannot be adjusted after the workpiece is fixed, the utility model provides a robot welding platform which can flexibly adjust the workpiece angle.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A robot welding platform includes a fixed frame, a placement plate installed on the fixed frame, and a workpiece clamping device installed on the placement plate. Its structural characteristics are: the workpiece clamping device includes two clamps installed opposite to each other, the clamps include a clamping platform, a rocker, a shaft rod and a clamper, the clamping platform is installed on the placement plate, the clamper is fixedly connected to one end of the shaft rod, the other end of the shaft rod is rotatably mounted on the clamping platform, and a shaft rod end cover is installed, and the rocker arm is fixedly connected to the shaft rod end cover.

[0009] The utility model adopts a workpiece clamping device with adjustable workpiece angle, that is, the clamp is rotatably connected to the clamping platform through a shaft rod, and the shaft rod is connected to a rocker as a driving end. The angle of the clamp can be adjusted as needed through the rotation of the rocker rod, thereby effectively avoiding the shortcomings of traditional robot welding platforms in the welding process, such as frequent disassembly of workpieces or increasing the number of robots to achieve welding at different positions of the workpiece, thereby effectively improving the welding efficiency.

[0010] Preferably, a plurality of connecting grooves are provided on the outer circumference of the shaft, and a limiting rod is installed on the clamping platform. The limiting rod is inserted into or disengaged from the connecting groove to fix the clamp at a certain angle through the limiting rod to meet the requirements of multi-angle welding.

[0011] Preferably, the clamp comprises two clamping plates, each having a fixing block attached to its inner wall. The two clamping plates are respectively threadedly connected to a compression spring rod, so that the distance between the two clamping plates can be adjusted by loosening or tightening the compression spring rod, thereby achieving clamping or removal of the workpiece. The fixing block is fixed to the clamping plate with bolts to facilitate its replacement.

[0012] Preferably, the workpiece clamping device is connected to the rigid porous placement plate by bolts so as to be moved when needed to meet different space requirements of the welding workpiece.

[0013] Preferably, the two clamps of the workpiece clamping device can work independently or in pairs, thereby improving the stability of the welding process.

[0014] Preferably, when the workpiece welding angle needs to be changed, there is no need to manually disassemble the workpiece, which can prevent the welding position from shifting or tilting when the workpiece is turned. Furthermore, the two clamps can support two workpieces in mid-air to meet the welding requirements.

[0015] Preferably, multiple dust hoods are installed above the workpiece clamping device, and a ventilation and dust removal system is installed below the fixed frame. The ventilation and dust removal system includes an air compressor, a heat exchanger and a filter box. The air inlet of the air compressor is connected to the air outlet of the filter box, and the air inlet of the filter box is connected to the dust hood via a ventilation duct system. The heat exchanger includes a water exchange tank. A water inlet pipe, a water outlet pipe, a first return air duct and a second return air duct are installed on the water exchange tank. One end of the first return air duct and the second return air duct is connected to the air outlet of the air compressor, and the other end is connected to the workshop ventilation duct, so as to achieve efficient purification of welding smoke in a small range of the workstation, and the purified return air is used to promote air circulation in the workshop.

[0016] Preferably, the air compressor, heat exchanger and filter box are tightly connected, the air compressor is equipped with sound insulation cotton, and the heat exchanger is equipped with an insulation board to improve the operating efficiency and stability of the equipment.

[0017] Preferably, a dust collecting port is installed below the workpiece clamping device, and the dust collecting port is connected to the air inlet of the filter box to further improve the smoke purification efficiency.

[0018] Preferably, the dust collecting port is funnel-shaped.

[0019] Preferably, the dust collection port is tightly attached to the placement plate via a soft magnet, allowing it to slide horizontally according to the welding position. The dust collection port can also be equipped with an adjustable valve to control the air volume of the dust collection port. When the smoke production at the welding point is low, only the dust collection port can be activated for dust collection.

[0020] Preferably, the ventilation duct system comprises a main ventilation duct, a first universal flexible tube, a second universal flexible tube, a third universal flexible tube, and a bracket. The main ventilation duct, the first universal flexible tube, the second universal flexible tube, and the third universal flexible tube are each detachably mounted on the bracket, with one end of each of the first universal flexible tube, the second universal flexible tube, and the third universal flexible tube connected in parallel to the inlet of the main ventilation duct, and the outlet of the main ventilation duct connected to the air inlet of the filter box. The other ends of each of the first universal flexible tube, the second universal flexible tube, and the third universal flexible tube are each mounted with a dust hood. Thus, the ventilation duct system is equipped with three dust suction ports formed by dust hoods. Each dust suction port may also be equipped with an on / off valve, and the dust suction speed and range may be controlled by the on / off valve, thereby meeting the dust suction requirements of multiple welding points without causing vibration that affects welding accuracy. Furthermore, the direction of action of each dust hood in the utility model can be flexibly adjusted via the universal flexible tube, avoiding the disadvantages of conventional vertical installation, which occupies a large welding space and limits the working radius of the welding robot. Furthermore, greater suction force is required to remove large particles of settling pollutants.

[0021] Preferably, an upper cavity for air intake, a fireproof material filter layer, a moisture absorption layer, an activated carbon layer and a lower cavity serving as a dust collecting cavity are sequentially arranged in the filter box, and the upper cavity is connected to the dust collecting port and the ventilation duct system.

[0022] Preferably, the filter box adopts a drawer-type design, which can easily clean and replace the formed layers.

[0023] Preferably, the bracket includes a main support plate, a connecting tube, a main sliding plate and a secondary sliding plate, the lower end of the main support plate is detachably mounted on the fixing frame, the upper end of the main support plate is sleeved with the lower end of the connecting tube, and the main support plate and the connecting tube are connected by fixing pins and limiting holes set on the main support plate and the connecting tube, the upper end of the connecting tube is slidably connected to the main sliding plate, and the main sliding plate is slidably connected to the secondary sliding plate, the main sliding plate and the secondary sliding plate are distributed in a cross shape, and the first universal flexible tube, the second universal flexible tube, and the third universal flexible tube are respectively mounted on the main sliding plate or the secondary sliding plate.

[0024] The utility model can be used as an automated robot welding platform. It realizes smoke purification and waste heat recovery and reuse during the welding process through a detachable bracket supporting the ventilation duct system, an air compressor as a power system, a filter box, a dust hood and its connecting pipes, and auxiliary valve components. At the same time, the welding angle can be adjusted through a workpiece clamping device with multiple degrees of freedom adjustment, thereby improving welding efficiency.

[0025] All connecting components in this utility model are removable and assembled to accommodate various application environments. The air compressor, heat exchanger, and filter box are bolted to the bottom support plate of the mounting bracket. The ventilation duct system is supported by brackets located on one side of the mounting bracket. The brackets can slide up and down, left and right, to facilitate adjustment of the ventilation duct system's installation height and coverage.

[0026] The utility model can realize suspended welding through the clamping of the clamp, and a plurality of dust suction hoods are arranged above the welding position and a dust collection port is arranged below, which can maximize the dust removal efficiency and is more conducive to preventing the escape of welding slag and smoke.

[0027] When using this welding robot platform, the gripper's rotation is controlled by a rocker. When the gripper reaches the desired angle, the workpiece can be clamped or removed. When placing the workpiece, the gripper's angle is aligned with the gripping platform's. The rocker is then rotated to adjust the gripper's angle to the welding angle. The workpiece's rotation is then restricted by the locking action of the limit rod and the connecting groove. The workpiece is tightened by tightening the compression spring rod, thus preparing for welding. When not welding, the workpiece gripper can be removed to keep the work surface (placement plate) clean and tidy.

[0028] The air compressor powers the entire system's fume removal system. One airflow is drawn in from the welding area, passing through the upper dust hood and into the main ventilation duct. Another airflow enters through the funnel-shaped dust collection port at the bottom. The two flows are mixed in the upper cavity of the filter box before being filtered. The opening and closing of each dust collection port is determined by the welding point and the amount of welding fume generated.

[0029] When the welding workload is heavy, the high-temperature and high-pressure gas compressed by the air compressor serves as the heat source for the heat exchanger's water exchange tank. After heat exchange, it is discharged into the workspace as circulating air to promote air flow disturbance in the workshop. At the same time, the cold water input from the water exchange tank through the cold water pipe absorbs heat in the water exchange tank to provide hot water supply for the workshop.

[0030] When the welding workload is small, the cold water inlet of the heat exchange water tank is closed, the dust collection hood on the top is also closed, and the air sucked in by the air compressor through the dust collection port is directly discharged after passing through the heat exchange water tank.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. The two workpiece clamping devices of the utility model can be freely disassembled, and the upper clamp can be rotated to complete the rotation, lifting and butt welding of the workpiece.

[0033] 2. In the utility model, multiple dust hoods are installed through a universal flexible tube, and the universal flexible tube is slidably installed on the top of the bracket through a main sliding plate or an auxiliary sliding plate distributed in a cross shape. The coverage of the dust hood can be adjusted by sliding the main sliding plate or the auxiliary sliding plate, and the air volume can be adjusted by a valve provided on the universal flexible tube.

[0034] 3. The filter box in this utility model is equipped with three-stage dust removal, which has high dust removal efficiency and good purification effect. The air outlet of the filter box can be used to realize circulating ventilation in the workshop, effectively improving the cleanliness of the working space.

[0035] 4. The heat exchanger in the utility model can effectively collect the heat of the air compressor and welding smoke, recover the waste heat, and have an energy-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] See also Figure 1An embodiment of the robot welding platform of the present invention includes a fixed frame 1, a rigid porous placement plate 2 installed on the fixed frame 1, and a workpiece clamping device 3 installed on the rigid porous placement plate 2. A plurality of dust hoods 30, 31, and 32 are installed above the workpiece clamping device 3, and a ventilation and dust removal system is installed below the fixed frame 1.

[0046] The workpiece clamping device 3 includes two clamps installed opposite to each other. Figure 2 As shown, the clamp includes a clamping platform 26, a rocker 19, a shaft 25, and a clamp 24 for clamping a workpiece. The clamping platform 26 is mounted on the placement plate 2. The clamp 24 is fixedly connected to one end of the shaft 25. The other end of the shaft 25 is rotatably mounted on the clamping platform 26. A shaft end cap 20 is mounted on the other end of the shaft 25. The rocker 19 is fixedly connected to the shaft end cap 20. When the rocker 19 is rotated, the shaft end cap 20 and the shaft 25 rotate synchronously, so that the clamp 24 can rotate with the workpiece, facilitating the adjustment of the workpiece welding angle.

[0047] The shaft 25 is provided with a plurality of connection grooves around its periphery. The limiting rod 22 is detachably mounted on the clamping platform 26 . When the limiting rod 22 is inserted into one of the connection grooves, the clamp 24 is positioned relative to the clamping platform 26 .

[0048] The clamp 24 comprises two clamping plates, each having a removable fixing block 23 attached to its inner wall. The two clamping plates are respectively threadedly connected to the compression spring rod 21. The removable design of the multiple fixing blocks 23 effectively reduces the overall wear of the device and allows for easy replacement if worn.

[0049] like Figure 3 As shown, the ventilation and dust removal system includes an air compressor 14, a heat exchanger 11 and a filter box 15. The air inlet of the air compressor 14 is connected to the air outlet of the filter box 15, and the air inlet of the filter box 15 is connected to the dust hoods 30, 31, and 32 through a ventilation duct system. The ventilation duct system includes a main ventilation duct 8, a first universal flexible tube 4, a second universal flexible tube 5, a third universal flexible tube 17 and a bracket 7. The bracket 7 is detachably connected to the fixed frame 1. The main ventilation duct 8, the first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 are respectively detachably installed on the bracket 7, and one end of the first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 are connected in parallel to the inlet of the main ventilation duct 8, and the outlet of the main ventilation duct 8 is connected to the air inlet of the filter box 15. The other ends of the first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 are respectively installed with the dust hoods 30, 31, and 32.

[0050] The heat exchanger 11 includes a heat exchange water tank 29. Figure 1 As shown, a water inlet pipe 9, a water outlet pipe 10, a first return air pipe 12, and a second return air pipe 13 are installed on the heat exchange water tank 29. One end of the first return air pipe 12 and the second return air pipe 13 are connected in parallel to the air outlet of the air compressor 14, and the other end is connected to the workshop ventilation pipeline.

[0051] A dust collecting port 16 is provided below the workpiece clamping device 3 . The dust collecting port 16 is preferably funnel-shaped and is tightly attached to the lower surface of the placement plate 2 via a soft magnet. The dust collecting port 16 is also connected to the air inlet of the filter box 15 .

[0052] like Figure 4 As shown, an upper cavity 35, a fire-insulating material filter layer 36, a moisture-absorbing layer 37, an activated carbon layer 38 and a lower cavity 39 are sequentially arranged in the filter box 15, and the upper cavity 35 is connected to the dust collecting port 16 and the outlet of the main ventilation duct 8.

[0053] like Figure 4 As shown, the bracket 7 includes a main support plate 34, an L-shaped connecting tube 40, a main sliding plate 27, and a secondary sliding plate 28. The main support plate 34 is detachably mounted on the fixed frame 1. The upper end of the main support plate 34 is connected to the limiting holes provided at the lower ends of the main support plate 34 and the connecting tube 40 via a fixing pin 33, thereby enabling the bracket 7 to be height-adjustable. The upper end of the connecting tube 40 is slidably connected to the main sliding plate 27, which is slidably connected to the secondary sliding plate 28. The main sliding plate 27 and the secondary sliding plate 28 are arranged in a cross shape. The first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 are respectively mounted on the main sliding plate 27 or the secondary sliding plate 28 via a tube clamp 6, allowing the coverage of the first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 and the dust hoods 30, 31, and 32 mounted at their ends to be adjustable.

[0054] When using the present invention, the bracket 7 and ventilation duct system must be pre-installed. To ensure the compactness of the equipment, the air compressor 14, filter 15, and heat exchanger 11 are all mounted on the bottom support plate 18 below the fixed frame 1. The bracket 7 is removably mounted on the fixed frame 1. The main ventilation duct 8, the first universal flexible tube 4, the second universal flexible tube 5, and the third universal flexible tube 17 are fixed to the bracket 7 via the pipe fixing clamp 6. The bracket 7 allows the installation height and coverage of the ventilation duct system to be adjusted. Regarding the workpiece clamping device 3, when holding the weld, first release the compression spring rod 21 to open the clamping jaws of the clamp 24, and place the weld into the clamping area of the workpiece clamping device 3. Then, re-tension the compression spring rod 21 to secure the weld. After the upper surface welding is completed, the weld can be adjusted to the appropriate position by rotating the crank handle 19. The position can be achieved by inserting the limit rod 22 into the corresponding connecting groove on the shaft 25 to continue welding at other locations. During butt welding operation, two clamps can be used to clamp the workpiece separately for operation. For special-shaped structures, the two clamps can also clamp at different angles.

[0055] The cleaning and energy-saving function of this utility model is implemented as follows: When in use, the air compressor 14 generates negative pressure. This negative pressure generates airflow that flows from bottom to top within the filter box 15, sequentially passing through the lower cavity 39, activated carbon layer 38, moisture-absorbing layer 37, fire-insulating filter layer 36, and upper cavity 35. It then splits into two paths: one directly reaching the dust collection port 16, and the other reaching the dust hoods 30, 31, and 32 via the ventilation duct system. The negative pressure airflow then carries the welding dust and gases through the upper cavity 35, fire-insulating filter layer 36, moisture-absorbing layer 37, activated carbon layer 38, and lower cavity 39 of the filter box 15, and then into the air compressor 14. The valves on the first, second, and third universal flexible tubes 4, 5, and 17 can be adjusted to open and close according to the amount of smoke generated during welding. The dust hoods 30, 31, and 32 are each equipped with a coarse iron filter mesh to prevent welding debris from dripping directly and damaging the cavity interlayer of the filter box 15. The small holes in the rigid porous plate 2 effectively collect large particles of smoke generated during welding. Compressed air from the air outlet of the air compressor 14 enters the heat exchanger 11's heat exchanger 11's heat exchanger 29 through a connecting pipeline for heat exchange. The heat exchanged (cooled) gas is then directly output through the first and second return air ports 12, 13, respectively, to promote air flow in the welding workshop and improve the working environment. When the heat exchanger 29 is in use, cold water is input through the water inlet pipe 9. After heat exchange, hot water flows out through the water outlet pipe 10 for hot water heating in the workshop.

[0056] When the system generates a large amount of heat, waste heat recovery is more valuable. At this time, the valve on the water outlet pipe 10 can be opened to drain the hot water directly. When the welding workload is light, the cold water inlet of the heat exchange tank 29 is closed, and the dust hood on the top is also closed. The air sucked in by the air compressor through the dust collection port passes through the heat exchange tank and is directly discharged. The utility model uses an adjustable bracket 7 to install the ventilation duct system, so that the dust hoods 30, 31, and 32 can be as close to the welding workpiece as possible, with a short air outlet short-circuit distance, thereby reducing direct contact between welders and welding dust and preventing large-scale diffusion of dust in the workshop.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification of the above embodiment made in accordance with the essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
