Description

Technical Field

[0001] This utility model relates to the field of robotic welding, specifically to a comprehensive automatic maintenance station for welding torches used in welding robots. Background Technology

[0002] During product manufacturing, welding operations are required for certain parts and components. A common method is gas shielded welding (such as carbon dioxide shielded welding), which necessitates the use of a welding torch. A typical welding torch consists of a contact tip and a nozzle, which are threaded together at the end of the torch. After a period of operation, the contact tip and nozzle will experience wear, especially the contact tip, which wears more rapidly. Worn contact tips affect welding quality, and severely poor welding quality can lead to market / customer complaints, product recalls, hefty compensation costs, and even company bankruptcy. Therefore, welding torches require maintenance after a certain period of use. Currently, most welding torch maintenance is done manually. However, due to the frequent maintenance required, manual replacement necessitates stopping the entire automated arc welding production line, inevitably reducing efficiency. Furthermore, existing automated welding torch maintenance devices are not highly integrated, are bulky, involve numerous and time-consuming maintenance steps, and occupy space near the robot, restricting its movement and increasing its travel distance and maintenance time.

[0016] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.

[0017] This utility model provides a comprehensive automatic maintenance station for welding torches used in welding robots, such as... Figure 1-8 As shown, the device includes an outer shell 1, an upper base frame 2 and a lower base frame 3 arranged parallel to each other within the outer shell 1, a support frame 4 disposed between the upper base frame 2 and the lower base frame 3, a welding torch processing area 5 and a conductive head processing area 6 disposed on the upper base frame 2, and a bidirectional clamping assembly 7 disposed between the welding torch processing area 5 and the conductive head processing area 6; the top of the outer shell 1 has a working window 8 corresponding to the welding torch processing area 5, the conductive head processing area 6, and the bidirectional clamping assembly 7; the welding torch processing area 5 is provided with a wire cutting module 52, a torch cleaning module 51, and an oil spraying module 53; the conductive head processing area 6 is provided with a conductive head disassembly and assembly module 61 and a conductive head replacement module 62; the bidirectional clamping assembly 7 includes a first clamping area 71 and a second clamping area 72, and the torch cleaning module 51 is located in the bidirectional clamping assembly 7. Below the first clamping area 71 of the clamping assembly 7, the conductive head replacement module 62 is located below the second clamping area 72 of the bidirectional clamping assembly 7; the wire cutting module 52 and the oil spraying module 53 are respectively located on both sides of the cleaning gun module 51. By setting the bidirectional clamping assembly 7, the welding gun can be clamped and fixed in both the welding gun processing area 5 and the conductive head processing area, thereby performing the corresponding welding gun cleaning action and conductive head disassembly and assembly action. This effectively reduces the number and structure of the fixing components, significantly reducing the overall volume of the welding gun integrated automatic maintenance station and reducing the occupation of the robot welding gun area. Furthermore, the wire cutting module 52 and the oil spraying module 53 are used to realize the wire cutting and oil spraying maintenance of the welding gun, and the conductive head disassembly and assembly module 61 and the conductive head replacement module 62 are used to realize the disassembly and replacement of the conductive head, making it fully functional.

[0018] Preferably, the bidirectional clamping assembly 7 includes a mounting frame 73, a clamping cylinder 74, a first clamping claw 75, and a second clamping claw 76. The clamping cylinder 74 is disposed within the mounting frame 73 and includes a first movable end and a second movable end disposed at the top of the clamping cylinder 74. The first clamping claw 75 faces the welding torch processing area 5 and is fixedly mounted in pairs on the first and second movable ends of the clamping cylinder 74. The second clamping claw 76 faces the conductive head processing area 6 and is fixedly mounted in pairs on the first clamping claw 75. By introducing gas into the clamping cylinder 74, the clamping cylinder 74 performs a clamping action, thereby driving the first clamping claw 75 and the second clamping claw 76 to perform synchronous clamping actions. This allows the welding torch to move into the interior of the first clamping claw 75 for clamping and fixing, and to cooperate with the torch cleaning module 51 for torch cleaning. Conversely, the welding torch can move into the interior of the second clamping claw 76 for clamping and fixing, and to cooperate with the conductive head loading and unloading module for assembling and disassembling the conductive head.

[0019] Preferably, the gun cleaning module 51 includes a first lifting cylinder 511 disposed on the upper base frame 2 and located below the first clamping claw 75, a lifting frame 512 disposed on the movable end of the first lifting cylinder 511, linear guide rails 513 disposed on both sides of the lifting frame 512 and fixedly installed with the upper base frame 2, a first rotary cylinder 514 fixedly installed on the lifting frame 512, a gun cleaning blade head 515 disposed on the top of the first rotary cylinder 514, and a first inclined groove 516 disposed below the first rotary cylinder 514 and a cleaning blade head 515 disposed on the outer casing 1. The first chip collection box 517, located below the tail end of the first inclined groove 516, moves the welding torch inside the first clamping claw 75 under robot control. The first clamping claw 75 is driven by the bidirectional clamping assembly 7 to clamp and fix the welding torch. The first rotary cylinder 514 is driven to rotate, and the first lifting cylinder 511 is driven to rotate and rise linearly, thereby cleaning the dirt inside the welding torch. The cleaned dirt falls into the first chip collection box 517. When the first chip collection box 517 is full, it is easy to directly pull out the first chip collection box 517 horizontally and empty the dirt.

[0020] Preferably, the wire-cutting module 52 includes a blade holder 521 with a slot, a first blade 522 fixedly installed in the slot, a first linear cylinder 523 disposed beside the blade holder 521, a second blade 524 disposed on the movable end of the first linear cylinder 523 and corresponding to the first blade 522, a second inclined groove 525 disposed below the blade holder 521, and a second chip collection box 526 disposed on the outer casing 1 and located below the tail end of the second inclined groove 525; the first blade 52... Both the first blade 522 and the second blade 524 have wire-cutting holes 527. The wire-cutting holes 527 of the first blade 522 and the second blade 524 are on the same vertical line. The welding wire is inserted into the wire-cutting holes 527 of the first blade 522 and the second blade 524 by the robot control. Then, the second blade 524 is driven to move linearly toward the first blade 522 by the first linear cylinder 523, so that the wire-cutting holes 527 of the first blade 522 and the second blade 524 are misaligned, thereby radially cutting the welding wire and causing the cut welding wire to fall into the second chip collection box 526.

[0021] Preferably, the oil spraying module 53 includes an oil spraying gun 531, an oil receiving box 532 disposed on the upper base frame 2 and located below the oil spraying gun 531, and an oil supply tank 533 disposed on the lower base frame 3. Oil is supplied to the oil spraying gun 531 through the oil supply tank 533, so that the maintenance oil is sprayed from the oil spraying gun 531 into the interior of the welding gun for maintenance. Excess oil after maintenance drips into the oil receiving box 532 for filtration and can be reused.

[0022] Preferably, a dust cover 11 is hinged to the top of the outer shell 1, and a second linear cylinder 12 is hinged to the upper base frame 2. The output end of the second linear cylinder 12 is hinged to the dust cover 11. By driving the second linear cylinder 12 to extend, the dust cover 11 is opened, thereby cooperating with the robot to perform welding torch maintenance work. After the maintenance work, the dust cover 11 is closed by retracting the second linear cylinder 12, so as to avoid the welding torch processing area 5 and the conductive head processing area 6 being exposed for a long time and reduce the accumulation of dust.

[0023] Preferably, the support frame 4 is equipped with several pneumatic solenoid valves 41 for controlling the clamping cylinder 74, the first lifting cylinder 511, the first rotating cylinder 514, the first linear cylinder 523, and the second linear cylinder 12; the lower base frame 3 is equipped with a communication port 31 for connecting to the robot controller for control linkage; and a controller 21 is provided below the upper base frame 2 for controlling the on / off state of the pneumatic solenoid valves 41.

[0024] The main advantages of this invention are: by setting up a bidirectional clamping component, the welding torch can be clamped and fixed in both the welding torch processing area and the conductive head processing area, thereby enabling corresponding torch cleaning and conductive head disassembly / reassembly actions. This effectively reduces the number and structure of fixing components, significantly reducing the overall size of the integrated automatic welding torch maintenance station and minimizing the area occupied by the robotic welding torch. Furthermore, the wire-cutting module and the oil spraying module enable wire-cutting and oil spraying maintenance of the welding torch, while the conductive head disassembly / reassembly module and conductive head replacement module enable the disassembly / replacement of the conductive head. The invention is fully functional and effectively reduces maintenance steps and shortens the maintenance time of the welding torch.

[0025] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
