DETAILED DESCRIPTION

[0029] In order to make the technical problems and beneficial effects of the technical solutions solved by the present application more clear and obvious, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0030] Please refer to Figures 1 to 6 , a double-station automatic wire feeding welding device, comprising a rack 1, a wire feeding device 2 and a welding wire device 3 arranged on the rack 1, and the wire outlet 21 of the wire feeding device 2 is arranged corresponding to the welding head 31 of the welding wire device 3.

[0031] The double-station automatic wire feeding welding device of the present application realizes automatic feeding and welding of welding wire by arranging the rack, the wire feeding device and the welding wire device, avoids the cumbersome steps of traditional manual welding ring installation, and significantly improves the welding efficiency. The wire outlet of the wire feeding device is arranged corresponding to the welding head of the welding wire device, which ensures that the welding wire is accurately and continuously fed into the welding position, reduces manual intervention, reduces time cost and improves production capacity.

[0032] Further, as a preferred embodiment of the present scheme but not limited, a moving device 4 is arranged on the rack 1, the rack 1 comprises a first station 11 and a second station 12, and the moving device 4 is used to switch the wire feeding device 2 and the welding wire device 3 between the first station 11 and the second station 12.

[0033] In the embodiment, the moving device is arranged on the rack, and the rack is divided into the first station and the second station, so that the wire feeding device and the welding wire device can be flexibly switched between the two stations, thereby realizing efficient welding operation of the double stations. While welding is completed in one station, the other station can perform loading and unloading or preheating and the like, which significantly improves the utilization rate and production efficiency of the equipment. The beneficial effects of this design are that, on the one hand, the idle time of the equipment is reduced, and continuous operation is realized; on the other hand, through the division of labor and cooperation of the double stations, the production rhythm is further optimized, the demand for manual intervention is reduced, and the welding quality and capacity are improved. An automatic detection device (such as a temperature sensing probe and a PID controller) can be additionally arranged on the station to monitor the welding temperature in real time and dynamically adjust the welding parameters, so as to adapt to the welding requirements of workpieces of different materials or shapes, and further improve the intelligent level and application range of the equipment.

[0034] Further, as a preferred embodiment of the present scheme but not limited, the wire feeding device 2 comprises a welding wire winding 22, a wire inlet 23 through which the welding wire at the welding wire winding 22 passes, and an output assembly 24 arranged between the wire inlet 23 and the wire outlet 21 for driving the welding wire to pass out of the wire outlet 21, and a straightening assembly 25 for straightening the welding wire before it enters the output assembly 24.

[0035] In the embodiment, the welding wire enters the straightening assembly from the welding wire winding through the wire inlet, is subjected to multi-directional straightening treatment by the transverse wheel and the longitudinal wheel in the straightening assembly, and is kept in a straight state before entering the output assembly, so as to avoid poor wire feeding or unstable welding quality caused by bending or twisting; then, the welding wire is fed into the output assembly, the gear set and the roller cooperating with the pulley driven by the servo motor realize precise control of the conveying speed and tension of the welding wire, and finally is stably output from the wire outlet to complete welding. The beneficial effects of this design are that, on the one hand, the straightness of the welding wire is significantly improved by the straightening assembly, the risk of wire jamming or wire breakage is reduced, and the reliability of equipment operation is improved; on the other hand, the precise control of the output assembly can ensure the uniformity and stability of the welding wire conveying, thereby improving the consistency and precision of welding.

[0036] Further, as a preferred embodiment of the present scheme but not limited, a conduit 26 for the welding wire to pass through is connected between the output assembly 24 and the wire outlet 21.

[0037] In this embodiment, the conduit provides a stable delivery channel for the welding wire, ensuring that the welding wire is accurately and smoothly delivered from the output assembly to the wire outlet, thereby avoiding the deviation, jitter or jamming of the welding wire during delivery due to external interference or its own elasticity. The beneficial effects of this design are that, on the one hand, the conduit can effectively protect the welding wire from the influence of the external environment (such as dust, impurities or mechanical impact) during delivery, thereby ensuring the quality and surface integrity of the welding wire; on the other hand, the presence of the conduit can further improve the stability and directionality of the welding wire delivery, especially in complex working conditions or long-distance delivery, which can significantly reduce the possibility of the welding wire deviating from the predetermined path, thereby improving the accuracy and reliability of the welding.

[0038] Further, as a preferred embodiment of the present scheme but not limited, the output assembly 24 comprises a mounting base 241, the mounting base 241 is provided with a servo motor 242, a driving gear 243 connected with the output end of the servo motor 242, a first driven gear 244 and a second driven gear 245 meshing with the driving gear 243 respectively, the first driven gear 244 and the second driven gear 245 are provided with a first roller 246 and a second roller 247, and the mounting base 241 is provided with a first pulley 248 and a second pulley 249 matched with the first roller 246 and the second roller 247 respectively to clamp the welding wire.

[0039] In this embodiment, the servo motor drives the driving gear, and the first driven gear and the second driven gear are driven to rotate by the driving gear, so as to drive the first roller and the second roller to cooperate with the corresponding first pulley and second pulley to clamp the welding wire and realize accurate delivery. By using the high precision characteristics of gear transmission and the clamping force between the roller and the pulley, it is ensured that the welding wire can maintain a constant speed and tension during delivery, avoiding welding quality problems caused by unstable wire feeding. On the one hand, the precise control ability of the servo motor enables the delivery speed of the welding wire to be dynamically adjusted according to the actual welding requirements, thereby adapting to the requirements of different welding processes; on the other hand, the cooperation and clamping structure of the roller and the pulley can reduce the damage to the surface of the welding wire while ensuring the stable delivery of the welding wire, thereby improving the quality and service life of the welding wire. In addition, adjustable pressure mechanisms can be added to the first pulley and the second pulley to flexibly adjust the clamping force according to the diameter or material of the welding wire, thereby better adapting to welding wires of different specifications; or a wear-resistant coating or special texture design can be added to the surface of the roller and the pulley to further reduce friction loss and improve clamping stability.

[0040] Further, as a preferred embodiment of the present scheme but not limited, the first pulley 248 and the second pulley 249 are provided with wire grooves 2410 corresponding to the position of the welding wire.

[0041] In this embodiment, a precise guide and fixed path is provided for the welding wire. The arrangement of the wire slot 2410 ensures that the welding wire always remains in the predetermined position during transmission, avoiding deviation or jumping of the welding wire, thereby improving the stability and precision of wire feeding.

[0042] Further, as a preferred embodiment of the present solution but not limited, the first roller 246 and the second roller 247 are externally sleeved with a rubber sleeve 5.

[0043] In this embodiment, the elastic deformation and friction characteristics of the rubber sleeve are used to form a flexible contact between the roller and the welding wire, thereby clamping the welding wire while avoiding hard damage or indentation to its surface. On the one hand, the rubber sleeve can provide sufficient friction to ensure stable transmission of the welding wire, while its flexibility can effectively buffer the pressure of the roller on the welding wire, reducing surface damage or deformation of the welding wire caused by excessive clamping force; on the other hand, the rubber sleeve also has a certain damping effect, reducing the instability of the welding wire caused by vibration or shaking during transmission, thereby further improving the precision and reliability of wire feeding. In addition, rubber sleeves of different materials (such as high-wear rubber, silicone or polyurethane) are used to adapt to different welding wire materials or working conditions. The high-wear rubber sleeve is suitable for high-strength use scenarios and can significantly prolong the service life of the roller, while the silicone sleeve is more suitable for precise welding scenarios with high requirements for welding wire surface protection, which can minimize surface scratches; or a special texture design (such as grooves or bumps) is added to the surface of the rubber sleeve to further enhance the friction and improve the stability of wire feeding.

[0044] Further, as a preferred embodiment of the present solution but not limited, the straightening assembly 25 includes a transverse mounting plate 251 and a longitudinal mounting plate 252, the transverse mounting plate 251 is provided with a plurality of transverse wheels 253 distributed along the left and right sides of the welding wire, and the longitudinal mounting plate 252 is provided with a plurality of longitudinal wheels 254 distributed along the upper and lower sides of the welding wire.

[0045] In this embodiment, a plurality of transverse wheels and longitudinal wheels are arranged on the transverse mounting plate and the longitudinal mounting plate respectively, the transverse wheels are used to correct the left and right deviation of the welding wire, and the longitudinal wheels are used to adjust the bending of the welding wire in the up and down direction, thereby cooperating in two perpendicular directions to gradually straighten the welding wire from the initial bent state to a straight state. On the one hand, the distribution of multiple groups of wheels can correct the bending of the welding wire step by step, avoiding surface damage or internal stress concentration caused by forced straightening at one time; on the other hand, the cooperation of the transverse wheels and the longitudinal wheels can cover all directional deformations of the welding wire, ensuring that the welding wire has high straightness after straightening, thereby improving the stability and precision of subsequent wire feeding and welding.

[0046] Further, as a preferred embodiment of the present scheme but not limited, the moving device 4 comprises a transverse sliding rail 41 arranged along the transverse direction of the first station 11 and the second station 12, a transverse sliding table 42 arranged on the transverse sliding rail 41, a transverse telescopic cylinder 43 driving the transverse sliding table 42 to slide along the transverse sliding rail 41, a longitudinal sliding rail 44 arranged on the transverse sliding table 42 and perpendicular to the transverse sliding rail 41, a longitudinal sliding table 45 arranged on the longitudinal sliding rail 44, a longitudinal telescopic cylinder 46 driving the longitudinal sliding table 45 to slide along the longitudinal sliding rail 44, and the longitudinal sliding table 45 is used to mount the wire feeding device 2 and the welding wire device 3.

[0047] In the present embodiment, the transverse telescopic cylinder is used to drive the transverse sliding table to move along the transverse sliding rail, thereby completing the horizontal switching of the equipment between the two stations, and the longitudinal telescopic cylinder is used to drive the longitudinal sliding table to move along the longitudinal sliding rail, thereby realizing the precise positioning of the equipment in the direction perpendicular to the transverse direction, so as to meet the multi-dimensional spatial adjustment requirements. On the one hand, the double-axis linkage sliding rail system significantly improves the flexibility and positioning accuracy of the equipment, so that the wire feeding device and the welding wire device can be quickly switched between different stations, reducing the idle time of the equipment and improving the production efficiency; on the other hand, the combination structure of the sliding rail and the cylinder has high stability and carrying capacity, which can ensure the smooth operation of the equipment during frequent movement, and avoid the welding quality problems caused by vibration or deviation.

[0048] Further, as a preferred embodiment of the present scheme but not limited, the moving device 4 comprises a transverse sliding rail 41 arranged along the transverse direction of the first station 11 and the second station 12, a transverse sliding table 42 arranged on the transverse sliding rail 41, a transverse telescopic cylinder 43 driving the transverse sliding table 42 to slide along the transverse sliding rail 41, a longitudinal sliding rail 44 arranged on the transverse sliding table 42 and perpendicular to the transverse sliding rail 41, a longitudinal sliding table 45 arranged on the longitudinal sliding rail 44, a longitudinal telescopic cylinder 46 driving the longitudinal sliding table 45 to slide along the longitudinal sliding rail 44, and the longitudinal sliding table 45 is used to mount the wire feeding device 2 and the welding wire device 3.

[0049] In this embodiment, the temperature sensing probe and the PID controller are combined to realize real-time monitoring and precise control of the workpiece temperature during welding. The working principle is that the temperature sensing probe detects the temperature of the workpiece to be processed and feeds back the data to the PID controller. When the workpiece temperature reaches the predetermined value, the PID controller starts the wire feeding device for welding, and at the same time, the servo motor accurately controls the delivery amount of the welding wire to ensure the stability and consistency of the welding process. After completing the welding of one station, the longitudinal telescopic cylinder and the transverse telescopic cylinder actuate together to quickly switch the equipment to another station and repeat the above process, thereby realizing continuous operation of double stations. The beneficial effects of this design are that on the one hand, the introduction of the temperature sensing probe and the PID controller can dynamically adjust the welding time according to the actual temperature of the workpiece, avoiding welding quality problems (such as virtual welding, overburning, etc.) caused by insufficient or excessive temperature, thereby significantly improving the welding quality. On the other hand, the automatic switching of the double stations greatly reduces the idle time of the equipment, improves the production efficiency, and at the same time reduces the demand for manual intervention, enhancing the intelligent level of production. When processing the workpiece to be processed at the first station, the PID controller controls the longitudinal telescopic cylinder to extend so that the welding head and the wire outlet reach the welding point position of the first station, and the wire feeding device starts to work. When the temperature sensing probe detects that the temperature of the workpiece to be processed reaches the predetermined temperature, the PID controller controls the wire feeding device to start wire feeding for welding. After the servo motor rotates for a predetermined time, the wire feeding is stopped, the longitudinal telescopic cylinder is retracted, and the transverse telescopic cylinder works to move to the second station. After the longitudinal telescopic cylinder extends, the welding head and the wire outlet reach the welding point position of the second station, and the wire feeding device starts to work. When the temperature sensing probe detects that the temperature of the workpiece to be processed reaches the predetermined temperature, the PID controller controls the wire feeding device to start wire feeding for welding. After the servo motor rotates for a predetermined time, the wire feeding is stopped, the longitudinal telescopic cylinder is retracted, and the transverse telescopic cylinder works to move to the first station. The process is repeated in this way.

[0050] Further, as a preferred embodiment of the present scheme but not limited, the temperature sensing probe is arranged on the rack 1 and located directly above the welding head 31.

[0051] In this embodiment, the temperature of the workpiece in the welding area is monitored in real time by the temperature sensing probe, and through the position advantage directly above it, the detection range covers the welding point and its surrounding area, thereby providing accurate temperature feedback data for the welding process. On the one hand, the position directly above the temperature sensing probe can avoid the direct attachment of spatter or smoke generated during the welding process on the probe, thereby reducing the risk of probe contamination and damage and prolonging its service life. On the other hand, this position can also minimize the interference of external environment (such as airflow or light) on temperature detection, improve measurement accuracy, and ensure the stability and reliability of welding temperature control. The temperature sensing probe is a non-contact infrared temperature measurement sensor with a protective cover to further reduce the impact of high-temperature spatter on the probe while improving detection efficiency and safety.

[0052] The working principle of this embodiment is as follows:

[0053] The double-station automatic wire feeding welding equipment of the present application realizes automatic feeding and welding of welding wire by setting up a rack, a wire feeding device and a welding wire device, avoids the cumbersome steps of traditional manual welding ring installation, and significantly improves welding efficiency.
