[0027] like Figure 1-Figure 6 As shown, the utility model provides an H-shaped double-station robot welding workstation for the rear triangle upper fork of a baby carriage frame, characterized in that it comprises: a closed working fence 14, a welding robot 7, and a workbench 2; the welding robot 7 is fixedly arranged in the working fence 14, two workbenches 2 are provided, the welding robot 7 is located between the two workbenches 2 and staggered with the workbenches 2 to form an H shape, an exhaust gas extraction device 13 for extracting welding exhaust gas is provided on the top of the working fence 14, a positioning fixture assembly 4 for fixing the frame is movably provided on each of the workbenches 2, the two workbenches 2 are parallel to each other, and a liftable automatic protective baffle 12 is also provided between the two workbenches 2;

[0028] Specifically, the working fence 14 is closed, and the working fence 14 can block the arc generated by the welding robot 7 during welding, so as to prevent the arc generated by the welding from affecting the workers. Two workbenches 2 are arranged at intervals in the working fence 14, and the two workbenches 2 are arranged in parallel. The welding robot 7 is located between the two workbenches 2 and is staggered with the workbenches 2 to form an H-shaped tooling table 19, thereby reducing the movement stroke of the welding robot 7 during welding, thereby improving the welding efficiency. A fixed base 20 is provided at the bottom of the welding robot 7 for supporting the welding robot 7. Four bottom brackets 6 are provided at the bottom of the workbench 2 for supporting the workbench 2. A positioning fixture assembly is provided on each workbench 2 4. The positioning fixture assembly 4 is movably connected to the workbench 2 to facilitate position adjustment. In order to prevent the exhaust gas generated during welding from being inhaled by the workers, an exhaust gas extraction device 13 is also provided on the top of the work fence 14. When the welding robot 7 is welding, the exhaust gas generated is discharged by the exhaust gas extraction device 13 through the ventilation duct 21, so that the workers will not inhale the exhaust gas when entering the work fence 14. A liftable automatic protective baffle 12 is also provided between the two workbenches 2. When the welding robot 7 is working, the automatic protective baffle 12 rises automatically to separate the two workbenches 2. At this time, the workers can dismantle the bracket or install the bracket on the other workbench 2 to ensure the safety of the workers.

[0029] It should be noted that a protective door 15 is provided on one side of the working fence 14 to facilitate the entry of the staff and prevent unauthorized persons from entering the working fence 14 .

[0030] Furthermore, a drive-control integrated control cabinet 8 for controlling the operation of the welding robot 7 is also provided in the working fence 14, a gas cylinder 9 and an intelligent MAG welder 10 connected to the gas cylinder 9 are also provided in the working fence 14, and the intelligent MAG welder 10 is connected to the welding robot 7;

[0031] Specifically, the integrated drive and control control cabinet 8 is used to control the operation of the welding robot 7, and the integrated drive and control control cabinet 8 has an emergency stop function. When an abnormal situation occurs, the staff can make an emergency stop through the integrated drive and control control cabinet 8 to ensure safety of use. The intelligent MAG welding machine 10 is used to realize the automation, intelligence and efficiency of the welding robot 7, and the gas cylinder 9 is used to assist the welding work of the welding robot 7.

[0032] Furthermore, in this embodiment, an automatic gun cleaning device 11 is provided between the two workbenches 2 to clean the welding slag on the welding head 18 of the welding robot 7;

[0033] Specifically, due to the long-term welding work of the welding robot 7, welding balls of the welding wire will appear, and the spatters generated during welding will stick to the vicinity of the welding head 18, causing the welding head 18 to be blocked. The existing technology deals with this situation by replacing the welding head 18, which leads to a significant increase in the cost of use. To avoid this situation, an automatic gun cleaning device 11 is provided between the two workbenches 2. After the welding work of the welding robot 7 is completed, the welding head 18 can be placed in the automatic gun cleaning device 11 by itself to clean the welding slag stuck on the welding head 18, thereby avoiding frequent replacement of the welding head 18, reducing the cost of use, and extending the service life of the welding head 18, avoiding the increased danger caused by frequent replacement of the gun head.

[0034] Among them, the automatic gun cleaning device 11 includes: a support base 25, a hopper 17 is fixed on the support base 25, and a wire cutting device 22 is provided above the hopper 17 for cutting the welding wire on the welding head 18; an oil spraying device 23 for spraying oil on the welding head 18 to facilitate the falling of welding slag on the welding head 18; a spatter processing device 24 for processing spatters adhering to the welding head 18. When the spatters on the welding head 18 are processed from the welding head 18, they will directly fall into the hopper 17.

[0035] Furthermore, a cooling device 16 is provided in the working fence 14 to reduce the temperature in the working fence 14;

[0036] Specifically, since the working fence 14 is closed, when the welding robot 7 is welding, high-temperature gas will be generated. At this time, although there is an exhaust gas extraction device 13, the temperature inside the working fence 14 will still be relatively high. In order to provide the staff with a comfortable working environment, a cooling device 16 is provided in the working fence 14. The cooling device 16 can effectively reduce the temperature inside the working fence 14. The welding power supply adopts air cooling to ensure that the working temperature of the welding robot 7 is not too high.

[0037] Further, in the present embodiment, two positioning fixture assemblies 4 are provided on each of the workbenches 2, and the positioning fixture assemblies 4 include: an upper support positioning fixture 3, a lower pressure positioning fixture 5, and an end positioning fixture 1.

The two end positioning fixtures 1 are arranged on the other side of the upper support positioning fixture 3; the positioning fixture assembly 4 also includes: a riser clamp, and the riser clamp is arranged on the side of the lower pressure positioning fixture 5 away from the upper support positioning fixture 3;

[0038] Specifically, each workbench 2 is provided with two positioning fixture assemblies 4, so that each workbench 2 can place two frames for welding at the same time, greatly improving the welding efficiency, wherein each positioning fixture assembly 4 includes an upper support positioning fixture 3, a lower pressure positioning fixture 5, and an end positioning fixture 1; there are two upper support positioning fixtures 3, which are arranged on the workbench 2 oppositely and at intervals, and are used to support the frame, and the two upper support positioning fixtures 3 are movably arranged on the workbench 2, and the interval distance between the two can be adjusted according to the use requirements to adapt to frames of different sizes; there is one lower pressure positioning fixture 5, which is movably arranged on the upper support positioning fixture One side of the positioning jig 3 is used to press the frame to prevent it from moving during welding; two end positioning jigs 1 are also provided, and the two end positioning jigs 1 are arranged opposite to each other and at intervals, and the two end positioning jigs 1 are arranged on the other side of the upper support positioning jig 3 to fix the end of the frame, and the two end positioning jigs 1 can also be movable on the workbench 2 to adapt to frames of different sizes; in this way, there is no need to replace the positioning jig when welding frames of different sizes, which is simple to use and convenient for workers to quickly locate and install, thereby improving work efficiency; the riser clamp is arranged on the side of the downward positioning jig 5 away from the upper support positioning jig 3 to fix the riser of the frame.

[0039] In summary, the present application reduces the movement range of the welding robot 7 and improves welding efficiency through the H-shaped double workstation. The automated protective baffle 12 is used to protect the workers during welding. The exhaust gas extraction device 13 is used to discharge the exhaust gas generated by the welding robot 7 during welding outside the working fence 14 to ensure the health of the workers. The positioning fixture assembly 4 is easy to use, and the workers can quickly perform positioning, installation, and disassembly, thereby improving work efficiency.
