[0002] There are many types of bicycles on the market, and the sizes of various pipes are inconsistent. The pipe fixing methods of different models are also different. When clamping and fixing children's bicycle pipes of different diameters, the corresponding mold size also needs to be changed. At the same time, in the existing welding environment, it is usually carried out in an open workshop. At this time, the exhaust gas generated by welding will be absorbed by the workers, causing harm to the workers' bodies. In addition, different parts of the children's bicycle pipes need to be welded from different angles during welding. The existing workbenches are all conventionally placed, which causes the welding robot to need to make unnecessary movements to achieve different welding angles, resulting in low welding efficiency. However, the existing workbenches are fixed and can only provide fixed position angles. The welding robot can only weld at the position and side provided by the workbench, but cannot weld at the bottom of the frame. At this time, the frame needs to be removed and installed upside down, which reduces the welding efficiency.

[0003] Therefore, it is urgent to design an eight-shaped double-station robot welding workstation for assembling a baby carriage frame to overcome the deficiencies of one or more of the above-mentioned prior arts. Utility Model Content

[0023] like Figure 1 As shown, the utility model provides an eight-shaped double-station robot welding workstation for assembling a baby carriage frame, which is characterized by comprising: a closed working fence 10, a welding robot 11, and an operation positioning platform 13; the welding robot 11 is fixedly arranged in the working fence 10, and two operation positioning platforms 13 are provided. The welding robot 11 is located between the two operation positioning platforms 13 and staggered with the operation positioning platforms 13. Each of the operation positioning platforms 13 is provided with a plurality of adjustment holes 131. The top of the working fence 10 is provided with a tool for extracting the welding robot. An exhaust gas extraction device 18 is connected to the exhaust gas, and each of the operation positioning platforms 13 is movably provided with a positioning fixture assembly for fixing the frame. The two operation positioning platforms 13 are respectively arranged at a 60° angle with the welding robot 11 to form an eight-shaped shape. A liftable automatic protective baffle 19 is also provided between the two operation positioning platforms 13. The end of the operation positioning platform 13 away from the welding robot 11 is provided with a positioner 20. The end of the operation positioning platform 13 is connected to the positioner 20, and the positioner 20 can drive the operation positioning platform 13 to rotate;

[0024] Specifically, the working fence 10 is closed, and the working fence 10 can block the arc generated by the welding robot 11 during welding, so as to prevent the arc generated by the welding from affecting the workers. Two spaced-apart operating positioning platforms 13 are provided in the working fence 10. The two operating positioning platforms 13 are respectively arranged at a 60° angle relative to the welding robot 11. The welding robot 11 is located between the two operating positioning platforms 13 and is staggered with the operating positioning platforms 13 to form an eight-shaped shape. As a result, the movement stroke of the welding robot 11 is reduced during welding, thereby improving the welding efficiency. A fixed base is provided at the bottom of the welding robot 11 for supporting the welding robot 11. A positioning fixture assembly is provided on each operating positioning platform 13, and a plurality of adjustment holes 131 are provided on each operating positioning platform 13. The positioning fixture assembly can be moved along the operating positioning platform 13 through the adjustment hole 131 to adjust the position for adapting to stroller frames of different sizes. In order to prevent the exhaust gas generated during welding from being inhaled by the workers, an exhaust gas extraction device 18 is also provided on the top of the working fence 10. When the welding robot 11 is performing welding, the exhaust gas generated is discharged through the ventilation duct by the exhaust gas extraction device 18, so that the staff will not inhale the exhaust gas when entering the work fence 10. A liftable automatic protective baffle 19 is also provided between the two operating positioning platforms 13. When the welding robot 11 is working, the automatic protective baffle 19 rises automatically to separate the two operating positioning platforms 13. At this time, the staff can remove the bracket or install the bracket on the other operating positioning platform 13 to ensure the safety of the staff. A positioner 20 is provided at the end of the operating positioning platform 13 away from the welding robot 11. The operating positioning platform 13 is fixedly connected to the positioner 20. The positioner 20 can control the operating positioning platform 13 to rotate, and the operating positioning platform 13 drives the baby carriage machine fixed thereon to rotate to adjust the welding position of the baby carriage frame. In conjunction with the multi-angle movement of the welding robot 11, all-round welding is achieved, so that a single baby carriage frame can be welded at all positions that need to be welded without manual adjustment, thereby improving welding efficiency.

[0025] It should be noted that a protective door 101 is provided on one side of the working fence 10 to facilitate the entry of staff and prevent unauthorized personnel from entering the working fence 10 .

[0026] Furthermore, in this embodiment, a drive-control integrated control cabinet 14 for controlling the operation of the welding robot 11 is further provided in the working fence 10. A gas cylinder 15 and an intelligent MAG welder 16 connected to the gas cylinder 15 are also provided in the working fence 10. The intelligent MAG welder 16 is connected to the welding robot 11.

[0027] Specifically, the integrated drive and control control cabinet 14 is used to control the operation of the welding robot 11, and the integrated drive and control control cabinet 14 has an emergency stop function. When an abnormal situation occurs, the staff can use the integrated drive and control control cabinet 14 for emergency stop to ensure safety of use. The intelligent MAG welder 16 is used to realize the automation, intelligence and efficiency of the welding robot 11, and the gas cylinder 15 is used to assist the welding work of the welding robot 11.

[0028] Furthermore, in this embodiment, an automatic gun cleaning device 17 is provided between the two operation positioning platforms 13 for cleaning welding slag on the welding head of the welding robot 11;

[0029] Specifically, since the welding robot 11 will produce welding balls of welding wire when it is working for a long time, the spatter produced during welding will stick to the vicinity of the welding head, causing the welding head to be blocked. The existing technology deals with this situation by replacing the welding head, which leads to a significant increase in the cost of use. To avoid this situation, an automatic gun cleaning device 17 is provided between the two operating positioning platforms 13. When the welding robot 11 completes the welding work, it can automatically place the welding head into the automatic gun cleaning device 17 to clean the welding slag stuck on the welding head, thereby avoiding frequent replacement of the welding head, reducing the cost of use, and extending the service life of the welding head, avoiding the increased danger of frequent replacement of the gun head.

[0030] Furthermore, in this embodiment, a cooling device 21 is further provided in the working fence 10 for reducing the temperature in the working fence 10;

[0031] Specifically, since the working fence 10 is closed, when the welding robot 11 is welding, high-temperature gas will be generated. At this time, although there is an exhaust gas extraction device 18, the temperature inside the working fence 10 will still be relatively high. In order to provide the staff with a comfortable working environment, a cooling device 21 is provided in the working fence 10. The cooling device 21 can effectively reduce the temperature inside the working fence 10. The welding power supply adopts air cooling to ensure that the working temperature of the welding robot 11 will not be too high.

[0032] Furthermore, in this embodiment, the positioning fixture assembly includes: a head tube positioning bracket 132, a seat tube positioning bracket 133, a rear fork positioning bracket 135, and a rear fork middle-end positioning bracket 134. The head tube positioning bracket 132 is integrally connected to one end of the operation positioning platform 13, and is used to fix the head tube of the baby stroller frame. The seat tube positioning bracket 133 is detachably connected to the adjustment hole 131, and is used to fix the seat tube of the baby stroller frame. The rear fork positioning bracket 135 is detachably connected to the adjustment hole 131, and is used to fix the rear fork of the baby stroller frame. The rear fork middle-end positioning bracket 134 is located between the rear fork positioning bracket 135 and the seat tube positioning bracket 133, and is detachably connected to the adjustment hole 131, and is used to fix the middle part of the rear fork of the baby stroller frame.

[0033] Specifically, the head tube positioning bracket 132 is integrally connected to one end of the operation positioning platform 13, and is in an L-shaped structure with the operation positioning platform 13. The head tube is used to fix the head tube part of the baby carriage frame. The seat tube positioning bracket 133 is detachably connected to the adjustment hole 131. The seat tube positioning bracket 133 can be moved along the operation positioning platform 13 to adjust the spacing distance between the head tube positioning bracket 132. The seat tube positioning bracket 133 is used to fix the five-way valve at the bottom of the seat tube. A rear fork middle end positioning bracket 134 is provided on the side of the seat tube positioning bracket 133 away from the head tube positioning bracket 132. The rear fork middle end positioning bracket 134 is detachably connected to the adjustment hole 131. The rear fork middle end positioning bracket 134 can be moved along the operation positioning platform The positioning platform 13 moves, and the rear fork middle-end positioning bracket 134 is used to support and fix the middle part of the rear fork of the baby stroller frame, wherein a rear fork positioning bracket 135 is provided on the side of the rear fork middle-end positioning bracket 134 away from the seat tube positioning bracket 133. The rear fork positioning bracket 135 is detachably connected to the adjustment hole 131 and can be moved along the operating positioning platform 13 to fix the rear end of the rear fork of the baby stroller frame. The baby stroller frame is fixed on a horizontal plane through the cooperation of each positioning bracket to facilitate welding. When the welding robot 11 is welding at some positions that are difficult to weld, the positioner 20 will drive the operating positioning platform 13 to rotate, driving the baby stroller frame to rotate synchronously to facilitate welding.

[0034] Furthermore, in this embodiment, the welding robot 11 is further provided with an automatic wire feeder 12 for feeding tin wire to the welding robot 11;

[0035] Specifically, the welding robot 11 is further provided with an automatic wire feeder 12 for automatically feeding welding wire to the welding robot 11 for welding.
