[0036] The present invention embeds the first hanger support rod 3 into the first rubber plate 5 and the first welding plate 6, and then embeds the second hanger support rod 4 into the second rubber plate 7 and the second welding plate 8, so that the subsequent step of welding the first hanger support rod 3 and the second hanger support rod 4 to the hanger main rod 2 is changed to welding the first welding plate 6 and the second welding plate 8 to the hanger main rod 2, thereby solving the problem that when welding the floor-standing hanger in the prior art, the contact surface between the first hanger support rod 3 and the second hanger support rod 4 and the hanger main rod 2 is too small, resulting in the first hanger support rod 3 and the second hanger support rod 4 being easily deflected, thereby reducing the aesthetics of the finished floor-standing hanger and affecting the product quality. The specific working process is as follows:

[0037] First, the staff embeds the four first hanger rods 3 into the first rubber plate 5 and the first welding plate 6, so that the first rubber plate 5 is deformed, so that the first rubber plate 5 clamps the first hanger rod 3, and then the first hanger rod 3 is placed on the ground, and the first hanger rod 3 is pressed downward to align the four first hanger rods 3 horizontally. Subsequently, the four second hanger rods 4 are embedded into the second rubber plate 7 and the second welding plate 8, so that the second rubber plate 7 is deformed, so that the second rubber plate 7 clamps the second hanger rod 4, and the above method is used to make The four second hanger support rods 4 are aligned horizontally, and then the hanger main rod 2 is transmitted from right to left through the conveyor belt 1. When the hanger main rod 2 moves to the position of the staff, the conveyor belt 1 is stopped to transmit the hanger main rod 2. Then, the staff holds the second rubber plate 7 and the second welding plate 8, and sleeves the second rubber plate 7 and the second welding plate 8 on the hanger main rod 2, and then pushes the second rubber plate 7 and the second welding plate 8 to move downward, thereby driving the second hanger support rod 4 to move downward, and aligning the first through groove 7001, the second fitting groove 8001 and the second through groove 8002 with the first The first protrusion 2001 makes the second rubber disc 7 and the second welding disc 8 continue to move downward, and the first protrusion 2001 passes through the first through groove 7001, the second fitting groove 8001 and the second through groove 8002. Then, when the second rubber disc 7 and the second welding disc 8 move downward to the second protrusion 2002, the second fitting groove 8001 fits with the second protrusion 2002, so that the second clothes hanger support rod 4, the second rubber disc 7 and the second welding disc 8 stop moving downward, and the second clothes hanger support rod 4, the second rubber disc 7 and the second welding disc 8 are positioned. Then, , the staff then puts the first rubber disc 5 and the first welding disc 6 onto the hanger main rod 2, and after aligning the first fitting groove 6001 with the first protrusion 2001, pulls the first rubber disc 5 and the first welding disc 6 downward, thereby driving the first hanger support rod 3 to move downward, so that the first protrusion 2001 is embedded in the first fitting groove 6001, and the first hanger support rod 3, the first rubber disc 5 and the first welding disc 6 are positioned, so that the first hanger support rod 3 and the second hanger support rod 4 are always kept on the same vertical axis, thereby improving the aesthetics of the finished product and improving the product quality.

[0038] Then, the conveyor belt 1 is restarted to transport the hanger main rod 2 from right to left, so that the first hanger support rod 3 and the second hanger support rod 4 move from right to left together. When the hanger main rod 2, the first hanger support rod 3 and the second hanger support rod 4 move to the lower side of the corrector 9, the conveyor belt 1 is stopped to transport the hanger main rod 2, the first hanger support rod 3 and the second hanger support rod 4, and then the first electric slider 102 is controlled to move downward along the first slide rail 101, thereby driving the corrector 9 to move downward, thereby stretching the corrugated hose 302, and making the smoking hood 301 move downward together with the corrector 9, so that the first hanger support rod 3 and the second hanger support rod 4 are gradually inserted into the limiting groove 9001 Since the upper side of each limiting groove 9001 is configured in a constricted shape, during the downward movement of the corrector 9, the first hanger support rod 3 is guided and limited by the upper limiting groove 9001, and the second hanger support rod 4 is guided and limited by the lower limiting groove 9001, so that the first hanger support rod 3 and the second hanger support rod 4 will gradually tend to the same axis under the extrusion and limitation of the limiting groove 9001, thereby avoiding the first hanger support rod 3 and the second hanger support rod 4 from deflecting during the transmission process, resulting in the first hanger support rod 3 and the second hanger support rod 4 not being on the same vertical axis, affecting the product quality. Subsequently, the corrector 9 moves downward to the position as shown in FIG. Figure 2 When the position is shown, the first electric slider 102 is stopped from moving downward, so that the corrector 9 stops moving downward, and then the second electric slider 202 is controlled to move downward along the second slide rail 201, thereby driving the manipulator 203 and the welding gun 204 to move downward, so that the first connection 6002 is welded by the welding gun 204, so that the first welding plate 6 is welded to the hanger main rod 2, and the first hanger support rod 3 is welded to the first welding plate 6. Compared with the existing welding process, the first hanger support rod 3 is directly welded to the hanger main rod 2, which avoids contact between the first hanger support rod 3 and the hanger main rod 2. The area is too small, which makes the first hanger support rod 3 easy to deflect during the welding process, and it is difficult to adjust the first hanger support rod 3 after deflection, which affects the aesthetics of the product and improves the product quality. Subsequently, the manipulator 203 and the welding gun 204 continue to move downward, and when moving to the second connection 8003, the second connection 8003 is welded by the welding gun 204, so that the second welding plate 8 is welded to the hanger main rod 2, and then the second hanger support rod 4 is welded to the second welding plate 8, thereby realizing the entire welding of the second hanger support rod 4, the first welding plate 6 and the second welding plate 8.

[0039] Then, during the welding process of the welding gun 204, the vacuum fan 303 is controlled to perform vacuuming, so that the welding smoke generated by the welding of the welding gun 204 moves upward along the fume hood 301 and the corrugated hose 302 to the vacuum fan 303 under the action of the vacuum fan 303, and then moves to the welding smoke purifier, so that the welding smoke is purified by the welding smoke purifier, thereby achieving the processing of the welding smoke, avoiding the welding smoke from affecting the workers and causing physical discomfort to the workers, thereby improving the protection effect on the workers.

[0040] Finally, after the welding of the first hanger rod 3 and the second hanger rod 4 is completed, the second electric slider 202 is controlled to move upward to the initial position, thereby driving the manipulator 203 and the welding gun 204 to move upward to the initial position. At the same time, the first electric slider 102 is controlled to drive the corrector 9 to move upward to the initial position, and then the conveyor belt 1 is started to move the hanger main rod 2, the first hanger rod 3 and the second hanger rod 4 to the next process.

[0041] Each first welding pad 6 is provided with a plurality of first positioning blocks 6003; each first positioning block 6003 corresponds one-to-one to the adjacent first interlocking groove 6001; each second welding pad 8 is provided with a plurality of second positioning blocks 8004; each second positioning block 8004 corresponds one-to-one to the adjacent second interlocking groove 8001; in the process of the staff moving the first welding pad 6 and the second welding pad 8 downward, the first interlocking groove 6001 and the second interlocking groove 8001 are positioned by the first positioning blocks 6003 and the second positioning blocks 8004, so that the staff can observe the positions of the first interlocking groove 6001 and the second interlocking groove 8001, and make it easier for the staff to embed the first protrusion 2001 and the second protrusion 2002 into the first interlocking groove 6001 and the second interlocking groove 8001.

[0042] The fume hood 301 is arranged in a stepped manner, so that the welding smoke can move to the middle of the fume hood 301 and then enter the corrugated hose 302, thereby improving the collection effect of the welding smoke.

[0043] It also includes a collecting box 304; the collecting box 304 is fixedly connected to the conveyor belt 1; the collecting box 304 collects the welding slag generated by the welding gun 204 to prevent the welding slag from falling directly on the conveyor belt 1, making the conveyor belt 1 difficult to clean and affecting the use of the conveyor belt 1.

[0044] The upper side of the collecting box 304 is flared to prevent welding slag from falling on the outside of the collecting box 304 and causing the welding slag to fall on the conveyor belt 1, thereby improving the collection effect of the collecting box 304 on the welding slag.

[0045] Example 2

[0046] On the basis of Example 1, Figure 2 , Figure 3 , Figure 8and Fig. 9 As shown, a cleaning brush 401 is also included; a plurality of cleaning brushes 401 are fixedly connected to the lower side of the corrector 9, and a plurality of hard bristles are densely arranged on the cleaning brush 401; all the cleaning brushes 401 are arranged in a circular array; in the process of the corrector 9 moving upward, the cleaning brush 401 will also move upward along with the corrector 9, so that the cleaning brush 401 brushes the first hanger support rod 3 and the first welding plate 6 and the second hanger support rod 4 and the second welding plate 8, so that the cleaning brush 401 cleans the welding slag adhered to the above-mentioned parts, avoids a large amount of welding slag adhering to the above-mentioned parts, reduces the difficulty of subsequent cleaning of the above-mentioned parts, and avoids a large amount of welding slag falling on the conveyor belt 1 during subsequent transmission, thereby reducing the cleaning and maintenance cost of the conveyor belt 1.

[0047] The side of each cleaning brush 401 close to the hanger main rod 2 is tilted upward; when the cleaning brush 401 moves upward to clean the welding slag adhered to the first hanger support rod 3 and the second hanger support rod 4, the cleaning brush 401 is tilted, and its hard bristles are tilted toward the first hanger support rod 3 and the second hanger support rod 4, producing a shoveling effect on the first hanger support rod 3 and the second hanger support rod 4, thereby improving the cleaning effect of the cleaning brush 401 on the welding slag adhered to the first hanger support rod 3 and the second hanger support rod 4.

[0048] It also includes a rubber rod 501 and a camera 502; each cleaning brush 401 is fixedly connected to a rubber rod 501; a camera 502 is arranged above the conveyor belt 1; when the welding gun 204 completes welding of the hanger main rod 2, the first hanger support rod 3 and the second hanger support rod 4, and the corrector 9 drives the cleaning brush 401 to move upward, the rubber rod 501 will move along with the cleaning brush 401, so that the rubber rod 501 squeezes the first hanger support rod 3 and the second hanger support rod 4, so that the rubber rod 501 is deformed, thereby passing over the first hanger support rod 3 and the second hanger support rod 4. If the welding strength of the first hanger support rod 3 and the second hanger support rod 4 is not enough, the rubber rod 501 will not be deformed. If the welded hanger rod 2, the first hanger rod 3 and the second hanger rod 4 are welded to the standard, the first hanger rod 3 and the second hanger rod 4 will become loose at the first connection 6002 and the second connection 8003 under the pressure of the rubber rod 501, so that the first hanger rod 3 and the second hanger rod 4 will deflect and will not be on the same vertical axis, resulting in misalignment. Subsequently, while the conveyor belt 1 continues to transmit the welded hanger main rod 2, the first hanger rod 3 and the second hanger rod 4 from right to left, the camera 502 is used to detect whether the first hanger rod 3 and the second hanger rod 4 are on the same vertical axis, thereby realizing the detection of the welding strength of the first hanger rod 3 and the second hanger rod 4 and improving product quality.
