[0002] Welding workstations, especially robotic welding workstations, are indispensable pieces of equipment in modern manufacturing. They are typically used to perform precise welding of parts and components, and are characterized by high efficiency, stability, and precision.

[0003] A welding workstation for a support assembly, disclosed in patent application CN211866947U, includes a welding robot, three workstations: Workstation 1, Workstation 2, and Workstation 3. Workstation 1 includes a first clamping unit, comprising a positioning block 1, a positioning component 1, and a spacing positioning device mounted on a plate 1. The positioning block 1 is used to position the base plate, and the positioning component 1 and the spacing positioning device are used to position the ear plate 1. Workstation 2 includes a second clamping unit, comprising a positioning block 2, a positioning component 1, and a clamping device mounted on a plate 2. The positioning block 2 and the clamping device are used to position the side plate 1. Workstation 3 includes a third clamping unit, comprising a positioning component 2 and a positioning component 1 mounted on a plate 3. The positioning component 2 is used to position the ear plate 2.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-5 This utility model provides two technical solutions:

[0025] The first embodiment: a front-support welding workstation, including a base plate 1, a welding robot 4 fixedly installed on the top surface of the base plate 1 for welding workpieces, wherein the welding robot 4 is an existing device for welding workpieces, and will not be described in detail here; a control box 5 for controlling the operation of the device is fixedly installed on the rear side of the top surface of the base plate 1, and also includes:

[0026] The fixing mechanism 2 is set on the top surface of the base plate 1 to fix the position of the workpiece. The fixing mechanism 2 also includes fixing boxes 21 fixedly installed on the left and right ends of the front side of the top surface of the base plate 1.

[0027] A collection mechanism 3, installed on the top surface of the fixed box 21, is used to collect exhaust gases generated during welding. The collection mechanism 3 includes a dust collection box 31 fixedly installed on the top surface of the fixed box 21. The front of the dust collection box 31 has several slots 32 for facilitating the entry of exhaust gases into the dust collection box 31. An air pipe 33 connects to the rear of the dust collection box 31. A dust collection box 34 for collecting exhaust gases is fixedly installed on the top surface of the base plate 1. The dust collection box 34 contains a filter assembly for filtering the exhaust gases. The collection mechanism 3 includes a dust collection box 31 fixedly installed on the top surface of the fixed box 21. The dust collection box 31 has several slots 32 on its front side to facilitate the entry of exhaust gas. These slots 32 are linearly and evenly distributed on the front side of the dust collection box 31. An air pipe 33 is connected to the rear side of the dust collection box 31. A dust collection box 34 for collecting exhaust gas is fixedly installed on the top surface of the base plate 1. A filter assembly for filtering exhaust gas is installed inside the dust collection box 34. The rear end of the air pipe 33 movably passes through the front side of the dust collection box 34 and extends into the interior of the dust collection box 34. The filter assembly is movably installed inside the dust collection box 34. The dust collection box 34 has a HEPA filter plate 35 for filtering exhaust gas, and a sealing gasket is fixedly installed on the outside of the HEPA filter plate 35 to improve the sealing performance of the device. The bottom surface of the inner cavity of the dust collection box 34 has a positioning groove 310 to improve the stability of the HEPA filter plate 35. A mounting bracket 38 is fixedly installed inside the dust collection box 34. Fans 39 for air intake are fixedly installed at both ends of the inner side of the mounting bracket 38. Several ventilation slots 37 are opened on the rear side of the dust collection box 34, and the ventilation slots 37 are linearly and evenly distributed on the rear side of the dust collection box 34. On the side, a buckle 36 for fixing the position of the HEPA filter plate 35 is fixedly installed on the top surface of the dust collection box 34.

The top surface of the HEPA filter plate 35 moves through the interior of the dust collection box 34 and is movably installed on the bottom surface of the buckle 36. The buckle 36 can fix the position of the HEPA filter plate 35. Opening the buckle 36 makes it easy to pull the HEPA filter plate 35 out of the dust collection box 34.

[0028] The dust collection box 31 and HEPA filter plate 35 facilitate the filtration of exhaust gas generated during welding. When welding, the fan 39 is turned on to draw the exhaust gas into the dust collection box 31 through the slot 32. Then, the exhaust gas flows through the air pipe 33 into the dust collection box 34 and passes through the HEPA filter plate 35 to filter out harmful substances in the exhaust gas. The filtered gas is then discharged outside the device through the ventilation slot 37, thus completing the filtration process and avoiding any impact on the health of the operators. This design is highly practical.

The bottom surface of the workpiece pallet 24 is slidably mounted inside the groove 23, and the movement trajectory of the workpiece pallet 24 can be limited by the groove 23.

[0030] The tooling frame 22 and workpiece clamping device 25 facilitate workpiece positioning. In use, the workpiece is placed on the top surface of the tooling frame 22 and positioned by the push rod 27 and positioning pin 28. Then, the position of the workpiece is fixed by the workpiece clamping device 25, and then the welding robot 4 can weld the workpiece. When it is necessary to adjust the angle of the workpiece or to flip it, the stepper motor 210 is started to drive the flipping disk 26 so that the tooling frame 22 can adjust the flipping angle of the workpiece. The structure is simple and the practicality is good.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the operator places the workpiece on the top surface of the fixture frame 22 and positions it using the top rod 27 and positioning pin 28.

When it is necessary to adjust the angle of the workpiece or flip it, the stepper motor 210 is started to drive the flipping disk 26 to adjust the flipping angle of the fixture frame 22. At the same time as welding, the fan 39 is started to draw the exhaust gas into the dust collection box 31 through the slot 32. Then, the exhaust gas flows through the air pipe 33 into the dust collection box 34 and is filtered by the HEPA filter plate 35 to remove harmful substances. The filtered gas is then discharged from the device through the ventilation slot 37. When it is necessary to replace the HEPA filter plate 35, the buckle 36 is opened and the HEPA filter plate 35 can be directly pulled out of the dust collection box 34 for replacement.
