Description

Technical Field

[0001] The utility model relates to the technical field of projection welding equipment, in particular to a welding slag collecting device for a projection welding workstation. Background Art

[0002] The projection welding workstation is a fully automated welding equipment, which includes a robot, a projection welding machine, a feeding belt and a unloading belt. When the projection welding workstation performs welding, the robot will grab the workpiece and move it to the projection welding machine for welding. During welding, the slag will form multiple metal sparks and splash everywhere, and after the splashes, they will fall to the ground to form welding slag;

[0003] The existing projection welding workstation does not have the function of collecting and processing metal sparks and welding slag, so when metal sparks fly, it is very likely to fall to the surrounding area, which can easily ignite the surrounding flammable materials and cause fire hazards. If it falls on the equipment line in the projection welding workstation, it will directly cause damage to the equipment and increase unnecessary economic expenses. At the same time, the welding slag that falls to the ground will not only pollute the operating environment, but also require manual cleaning, which will directly increase the labor intensity of the operators.

[0020] like Figure 1 , 2 As shown, a slag collection device for a projection welding workstation includes a manipulator 1 and a loading belt 13 and a unloading belt 14 on its side and a projection welding machine 2, wherein a compressed gas tank 3 is arranged on the upper portion of the projection welding machine 2, a cylinder 4 is arranged on the side portion of the projection welding machine 2, a mounting plate 41 is connected to the telescopic rod of the cylinder 4, an upper electrode 5 is connected to the side wall of the mounting plate 41, a lower electrode 6 is arranged directly below the upper electrode 5, a retractable protective cover 7 is arranged at the lower portion of the mounting plate 41 and is sleeved with the upper electrode 5, a waste box 10 for collecting welding slag is arranged at the lower portion of the lower electrode 6, and a chip blowing assembly is arranged obliquely above the lower electrode 6.

[0021] like Figure 3 As shown, the protective cover 7 includes an upper shell 71 connected and fixed to the lower side of the mounting plate 41 , and a cavity is provided in the middle of the upper shell 71 , and a lower shell 72 is slidably connected in the cavity.

[0022] like Figure 4 As shown, a slide plate 101 inclined toward the middle is arranged in the waste box 10, and a receiving box 11 which can be pulled out in the waste box 10 is arranged below the slide plate 101.

[0023] like Figure 1 As shown, a handle 12 for easy pulling is provided on the side of the receiving box 11.

[0024] like Figure 1 , 2 As shown, the chip blowing assembly includes a diverter pipe 8 connected to the side of the projection welding machine 2, and a plurality of purge pipes 9 for blowing away welding slag are axially distributed on the side of the diverter pipe 8. An air inlet 91 is provided at the tail end of the diverter pipe 8, and the air inlet 91 is connected to the splitter 31 of the compressed gas tank 3 through an air pipe.

[0025] like Figure 1 , 2 The pore diameter of the purge tube 9 shown is 3-5 mm.

[0026] The implementation principle of the welding slag collection device of a projection welding workstation in the embodiment of the present application is:

[0027] When performing welding operations, multiple workpieces are first placed on the feeding belt 13 in sequence, and the feeding belt 13 transports the workpieces to a set position (set according to the on-site conditions). The manipulator 1 grabs the workpiece and moves the position to be welded to the upper part of the lower electrode 6 of the projection welding machine 2. After moving to the upper part of the lower electrode 6, the cylinder 4 is started, and the telescopic rod of the cylinder 4 drives the upper electrode 5 connected to the mounting plate 41 to move downward;

[0028] During the downward movement, since the upper electrode 5 is inside the protective cover 7, the lower shell 72 of the protective cover 7 will first contact the workpiece during the downward movement of the upper electrode 5, and will continue to move downward after contacting the workpiece, so that the lower shell 72 is partially blocked by the workpiece and moves up into the cavity of the upper shell 71, and at the same time, the lower shell 72 of the protective cover 7 will fit closely with the workpiece by its own weight;

[0029] After the upper electrode 5 contacts the workpiece, welding begins. During welding, the slag will form multiple metal sparks and splash around. The splashing will be blocked by the protective cover 7 that fits tightly with the surface of the workpiece. The blocked metal sparks will form welding slag and will fall onto the workpiece and the platform supporting the lower electrode 6. After welding is completed, the cylinder 4 retracts to pull the upper electrode 5 and the protective cover 7 away from the workpiece.

[0030] At the same time, the compressed gas tank 3 starts to supply gas to the shunt pipe 8, and the gas will enter the shunt pipe 8 along the gas pipe and be discharged from each purge pipe 9 to the workpiece and the platform supporting the lower electrode 6, thereby realizing the process of cleaning the welding slag on the workpiece and the upper part of the platform supporting the lower electrode 6;

[0031] The welding slag after air blowing will fall onto the slide 101 in the waste box 10, and the welding slag falling onto the slide 101 will slide down along the inclined surface and slide into the receiving box 11 in the waste box 10, thereby completing the cleaning and collection of welding slag of one welding point, and the rest of the welding will continue according to the above steps. The whole process can prevent metal sparks from splashing and clean up and collect welding slag, which is time-saving and labor-saving, better guarantees the normal production of the enterprise, avoids unnecessary economic expenditure, and reduces the labor intensity of the operators;

[0032] When the material receiving box 11 is full of welding slag, the handle 12 is pulled to pull the material receiving box 11 out of the waste box 10, and then the welding slag is inverted at a designated position, and then the material receiving box 11 is placed in the waste box 10 to start receiving materials.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
