[0030] Reference Figures 1 to 5 The nut welding workstation of the utility model is implemented as follows:

[0031] A nut welding workstation includes: a welding unit 100, a bracket feeding device 200, a welding loading device 300 and a nut feeding device 400.

[0032] The support feeding device 200 is used to continuously supply welding supports. The welding unit 100 has a welding station and a welding head disposed toward the welding station. The welding loading device 300 is used to move the welding supports from the support feeding device 200 to the welding station.

[0033] The nut feeding device 400 includes: a nut feeding member, a feeding seat 420, a feeding rod 430 and a feeding drive unit 440. The feeding seat 420 has a feeding positioning groove. The nut feeding member is used to continuously supply welding nuts to the feeding positioning groove. The axial direction of the feeding rod 430 is arranged along the line connecting the feeding positioning groove and the welding station. The feeding drive unit 440 is used to drive the feeding rod 430 to move axially.

[0034] In actual use, the welding loading device 300 moves the welding bracket from the bracket feeding device 200 to the welding station, the welding nut of the nut feeding component falls into the feeding positioning groove, the feeding drive unit 440 drives the feeding rod 430 to extend, and the feeding rod 430 pushes the welding nut in the feeding positioning groove to the welding station, and then the welding unit 100 is used to realize the welding process of the welding nut and the welding bracket.

[0035] In this embodiment, the welding feeding device 300 is arranged front and back with the welding unit 100. The welding unit 100 is arranged at the front end of the welding nut workstation. The welding feeding device 300 is arranged at the rear of the welding unit 100. The bracket feeding device 200 includes: a bracket vibration plate 210 and a bracket direct vibration 220. The bracket vibration plate 210 and the bracket direct vibration 220 are connected. The welding feeding device 300 uses a four-axis robot to drive the bracket gripper. The bracket gripper is used to grab the welding bracket. The number of the bracket feeding devices 200 is multiple, and the multiple bracket feeding devices 200 are distributed on the side of the welding feeding device 300. Referring to the drawings, in this embodiment, the number of the bracket feeding devices 200 is four, and the bracket direct vibrations 220 of the four bracket feeding devices 200 are all arranged toward the welding feeding device 300.

[0036] In some other embodiments, the welding feeding device 300 can also use a three-axis drive module to drive the bracket gripper. The bracket gripper is moved by linear drive modules arranged in the left-right direction, the front-back direction, and the up-down direction, so as to realize the movement and feeding of the welding bracket. The bracket gripper can drive two claws to clamp toward each other through the claw cylinder to realize the clamping and placement of the welding bracket. The bracket gripper can also use a vacuum suction cup to adsorb and place the welding bracket.

[0037] The nut feeding component includes a feeding blow pipe 410. One end of the feeding blow pipe 410 is connected to a feeding source of the welding nut and communicated with a high-pressure gas source, and the other end of the feeding blow pipe 410 is communicated with the feeding positioning groove.

[0038] In this embodiment, the supply source of the weld nut can adopt a corresponding weld nut vibration plate and direct vibration, so that the weld nut can be continuously supplied. When the weld nut is transported to the end of the feed blow pipe 410 through the vibration plate and direct vibration, the high-pressure gas source is turned on to blow the weld nut along the feed blow pipe 410 to the feed seat 420, so that the weld nut falls into the feed positioning groove, and the weld nut is fed.

[0039] It is worth noting that in this embodiment, the welding nut is a square nut, and the feed blow pipe 410 is a square tube. The inner cavity cross section of the feed blow pipe 410 is rectangular, and the inner cavity size of the feed blow pipe 410 is set according to the size specification of the welding nut, so that the welding nut can move along the inner cavity of the feed blow pipe 410 without turning over.

[0040] The feed seat 420 has a feed channel that is arranged through, and the feed positioning groove is arranged at one end of the feed channel facing the welding station. A guide tube 422 and a cover plate 421 are respectively arranged at the two axial ends of the feed channel. The cover plate 421 can be opened and closed on the side of the feed seat 420 facing the welding station, and the guide tube 422 is arranged on the other side and extends along the axial direction of the feed channel. The feed rod 430 is movably arranged in the guide tube 422. The feed drive unit 440 can adopt a linear drive component such as a cylinder, an electric push rod, a hydraulic push rod, etc. The feed drive unit 440 is arranged at one end of the guide tube 422 away from the feed seat 420, and the output end of the feed drive unit 440 is connected to the feed rod 430.

[0041] Further, the feed rod 430 includes a rod body and a material-penetrating portion 431. The rod body is in the shape of an elongated cylinder, and the material-penetrating portion 431 is provided at one end of the rod body facing the welding station, and the material-penetrating portion 431 is in the shape of a cylinder. The diameter of the material-penetrating portion 431 is smaller than the inner diameter of the welding nut, and the diameter of the rod body is larger than the inner diameter of the welding nut.

[0042] In order to prevent the welding nut from getting stuck, the feed blow pipe 410 extends in a curve with an arc transition. The end of the feed blow pipe 410 is arranged along the radial direction of the feed channel. When the welding nut falls into the feed positioning groove along the feed blow pipe 410, the cover plate 421 can restrict it in the feed positioning groove.

[0043] The feed drive unit 440 drives the feed rod 430 to extend along the feed channel, and the feed-through portion 431 is inserted into the screw hole of the welding nut, and pushes the cover plate 421 open, and extends to the welding station. The end of the rod body presses against the welding nut so that it moves with the feed-through portion 431. When the feed rod 430 is extended to the limit position, the welding nut slides down to the lower end along the feed-through portion 431 under the action of its own weight, thereby contacting the welding bracket on the welding station, and then the welding process is realized through the welding unit 100.

[0044] In this embodiment, one end of the cover plate 421 is elastically hinged to the feed seat 420. The cover plate 421 is arranged on the end face of the feed seat 420 facing the welding station, and one end of the cover plate 421 is hinged to the feed seat 420, and the cover plate 421 is elastically pressed against the end face of the feed seat 420 by the elastic force of the torsion spring to limit the welding nut in the feed positioning groove.

[0045] In order to improve the flexibility of the nut feeding device 400, the nut feeding device 400 is preferably adjustable. The nut feeding device 400 is adjustably arranged beside the welding unit 100, so that the angle of the ejection direction of the welding nut can be flexibly adjusted according to demand.

[0046] In this embodiment, the welding unit 100 is adjustably mounted with a connecting rod 520 , a connecting block 530 is provided between the connecting rod 520 and the feeding seat 420 , and two ends of the connecting block 530 are adjustably sleeved on the connecting rod 520 and the feeding seat 420 , respectively.

[0047] Specifically, the connecting rod 520 is a long round rod and extends in an "L" shape. The cross section of the connecting rod 520 is circular. The welding unit 100 is fixedly provided with a connecting seat 510. The connecting seat 510 has a mounting hole extending up and down, and the connecting rod 520 is inserted into the mounting hole.

[0048] Both ends of the connection block 530 have connection holes, and the axes of the two connection holes are perpendicular to each other. The middle part of the conduit 422 has a cylindrical connection end. The connection end and the connection rod 520 are respectively inserted into the two connection holes. The connection hole and the mounting hole are both locked by screws, so as to clamp and lock the connection rod 520 or the connection end.

[0049] When the screw of the mounting hole is loosened, the connecting rod 520 can rotate relative to the connecting seat 510. Similarly, the guide tube 422, the connecting block 530 and the connecting rod 520 can be relatively rotated and adjusted, so as to adjust the installation posture of the feeding seat 420 to meet the different ejection angle requirements of the welding nut.
