Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and in particular relates to a control device and system for intelligent welding. Background Art

[0002] In the field of modern welding technology, intelligent welding systems are increasingly being used. These systems can automatically adjust the flow of shielding gas according to different working conditions, such as the material of the welding target, the current size, and the welding speed, in order to optimize the welding process and improve the quality of the weld. However, although the existing technology has made some progress in regulating the flow of shielding gas, there are still some key issues that have not been fully addressed.

[0003] First of all, the current intelligent welding system often ignores the influence of wire feeding speed when controlling gas flow. Wire feeding speed is an important parameter in the welding process, which directly affects the effective coverage of the shielding gas and the quality of the weld formation. If the wire feeding speed is too fast, the speed of the welding wire supply exceeds the reasonable range, which will lead to a relatively insufficient shielding gas flow, making the arc unstable and causing sputtering. On the contrary, if the wire feeding speed is too slow, it may cause the shielding gas flow to be too large, thereby increasing the generation of bubbles and pores in the weld, affecting the welding quality.

[0004] Secondly, the stability of the wire feeding speed mainly depends on the performance of the wire feeding equipment. In the prior art, the wire feeding equipment usually realizes the feeding of the welding wire by the cooperation of the feeding wheel and the pressing wheel. However, the clamping force applied to the welding wire is one of the factors that cannot be ignored in determining the stability of the wire feeding speed. If the clamping force is too large, it will not only accelerate the wear of the pressing wheel, but also may cause the welding wire to deform and increase the wire feeding resistance; if the pressure is too small, it may cause the feeding wheel to slip, affecting the continuity and stability of the wire feeding. In the prior art, the real-time adjustment of the clamping force on the welding wire has not yet been effectively implemented.

[0005] Therefore, although the existing intelligent welding system has made technological innovations in many aspects, there is still room for improvement in comprehensively considering the impact of wire feeding speed on shielding gas flow and the stability of wire feeding equipment. In order to further improve welding quality and efficiency, it is necessary to develop a new type of intelligent welding gas flow control system and device to realize real-time monitoring and adjustment of the clamping force of the wire feeding equipment to ensure the stability of the welding process and the high quality of the weld. Summary of the invention

By adjusting the rotation direction of the voltage regulating motor and driving the pressure wheel to move, the size of the clamping force applied to the surface of the welding wire can be adjusted in real time to ensure the stability and continuity of the welding wire transportation and avoid relative changes in the shielding gas flow rate caused by unstable wire feeding speed.

[0048] Embodiment 1

[0049] Please see attached Figures 1 to 4 As shown in the figure, it is the first embodiment of the present invention, which provides an intelligent welding control device suitable for welding wire feeding, including a wire feeder body 10, the interior of the wire feeder body 10 is fixed with a positioning side plate 11 and a wire feeding motor 12 in sequence from one side to the other side, and the output end of the wire feeding motor 12 passes through the positioning side plate 11, and a driving gear 13 is fixed to the output end of the wire feeding motor 12 and located on one side of the positioning side plate 11, and a plurality of wire feeding wheels 14 are rotatably connected to one side of the positioning side plate 11 and located at both ends of the driving gear 13, and the wire feeding wheels 14 are close to the positioning side plate 11. A driven gear is fixed to one side of the positioning side plate 11, and the driving gear 13 and the wire feeding wheel 14 are meshed and connected through the driven gear. A welding wire reel 15 is installed at one end of the wire feeding machine body 10, and a wire outlet nozzle 16, a wire guide nozzle 17 and a wire inlet nozzle 18 are fixed to one side of the positioning side plate 11 from one end to the other end in sequence, and a plurality of wire feeding wheels 14 are respectively arranged between the wire outlet nozzle 16 and the wire guide nozzle 17 and between the wire guide nozzle 17 and the wire inlet nozzle 18, and a control box 19 is installed at the upper end of the wire guide nozzle 17, and the wire feeding motor 12 and the control box 19 are electrically connected through a wire, and also include:

[0050] A plurality of pressurizing parts 20, the plurality of pressurizing parts 20 and the plurality of wire feeding wheels 14 correspond one to one, the pressurizing part 20 comprises a crank 21, a transmission block 22, a pressure sensor 23 and a pressurizing wheel 24, the crank 21 is rotatably connected to one side of the positioning side plate 11, the transmission block 22 is arranged on one side of the positioning side plate 11, and the crank 21 and the transmission block 22 are slidably connected, the pressure sensor 23 is fixed to the lower end of the transmission block 22, and the pressure sensor 23 and the control box 19 are electrically connected through a wire, the pressurizing wheel 24 is fixed to the lower end of the pressure sensor 23, and the pressurizing wheel 24 and the wire feeding wheel 14 are adapted;

[0051] A voltage regulating driving unit 30, which is installed between the plurality of pressurizing units 20, and the voltage regulating driving unit 30 is connected to the crank 21, and the voltage regulating driving unit 30 can drive the plurality of pressurizing units 20 to operate;

[0052] A cleaning portion 40, the cleaning portion 40 is mounted on an end of the positioning side plate 11 away from the wire feeding motor 12;

[0053] After the welding wire passes between the wire feeding wheel 14 and the pressure wheel 24 , the pressure sensor 23 can obtain the pressure applied by the pressure wheel 24 on the welding wire in real time.

[0054] It should be noted that a welding gun is also used in conjunction with the wire feeder body 10. A wire guide hose is provided at the input end of the welding gun, and the wire guide hose is connected to the wire outlet nozzle 16. The welding wire passes through the cleaning part 40, the wire input nozzle 18, the wire guide nozzle 17, the wire outlet nozzle 16 and the wire guide hose in sequence and is transported to the output end of the welding gun.

[0055] In this embodiment, a welding wire reel 15 wound with welding wire is assembled on the wire feeder body 10, and the welding wire is sequentially passed through the cleaning portion 40, the wire inlet nozzle 18, the wire guide nozzle 17 and the wire outlet nozzle 16 and inserted into the welding gun, and the voltage regulating driving portion 30 is started. Since the voltage regulating driving portion 30 is connected to the crank 21, the crank 21 is driven to rotate by the voltage regulating driving portion 30, so that the cranks 21 in the two pressurizing portions 20 rotate in a direction close to each other. Since the crank 21 is slidably connected to the transmission block 22, the crank 21 is driven to rotate by the crank 21. The handle 21 drives the transmission block 22 to move in the vertical direction. The transmission block 22 drives the pressure sensor 23 and the pressure wheel 24 to move downward through the fixed connection between the transmission block 22 and the pressure sensor 23 and the fixed connection between the pressure sensor 23 and the pressure wheel 24. When the pressure wheel 24 contacts the welding wire, the welding wire is squeezed by the pressure wheel 24 so that the welding wire and the wire feeding wheel 14 fit closely together. The pressure sensor 23 obtains the clamping force applied to the surface of the welding wire in real time. If the clamping force is less than the target value, the pressure is adjusted. The driving unit 30 drives the crank 21 to continue to rotate, increasing the clamping force applied to the surface of the welding wire until the clamping force is equal to the target value; if the clamping force is equal to the target value, the voltage regulating driving unit 30 is closed and the crank 21 is stopped from rotating; if the clamping force is greater than the target value, the crank 21 is driven to rotate in the opposite direction by the voltage regulating driving unit 30 to reduce the clamping force applied to the surface of the welding wire until the clamping force is equal to the target value, and the wire feeding motor 12 is started, and the driving gear 13 is driven to rotate by the output end of the wire feeding motor 12, and the driving gear 13 and the wire feeding wheel 14 are meshed and connected, so that the driving gear 13 drives the wire feeding wheel 14 to rotate, and the wire feeding wheel 14 and the pressure wheel 24 cooperate to convey the welding wire. Through the above-mentioned scheme, the clamping force applied to the surface of the welding wire can be ensured to be in a stable state, and the wire feeding speed fluctuation caused by the unstable clamping force during the welding wire feeding process can be avoided, thereby improving the stability and continuity of the wire feeding. At the same time, the relative change of the gas flow caused by the unstable wire feeding speed is avoided, thereby improving the stability of the gas flow control system.

[0056] It should be noted that different diameters of welding wires require different clamping forces. The control box 19 can preset the clamping force target value according to the diameter of the welding wire. The preset clamping force values ​​corresponding to welding wires of different diameters can be adjusted through actual operating experience and combined with relevant test data.

[0057] Next, please refer to Figure 3 and Figure 4 As shown, a first guide rod 25 is fixed to the upper end of the transmission block 22, a guide plate 26 is fixed to the upper end inside the wire feeder body 10, and the first guide rod 25 and the guide plate 26 are slidably connected, transmission rods 27 are provided on both sides of the transmission block 22, and a plurality of guide grooves 28 are provided on both sides of one end of the crank 21, and the plurality of transmission rods 27 and the plurality of guide grooves 28 correspond one to one, and the crank 21 and the transmission block 22 are slidably connected through the cooperation of the transmission rod 27 and the guide groove 28.

[0058] In this embodiment, after the voltage regulating drive unit 30 is operated, since the crank 21 and the voltage regulating drive unit 30 are connected, the crank 21 is driven to rotate by the voltage regulating drive unit 30, and the guide groove 28 is driven to rotate synchronously by the crank 21. Since the transmission rod 27 and the guide groove 28 are slidably connected and the transmission rod 27 and the transmission block 22 are fixedly connected, the transmission block 22 is driven to move by the crank 21. Since the wire feeder body 10 and the guide plate 26 are fixedly connected and the first guide rod 25 and the guide plate 26 are slidably connected, when the crank 21 drives the transmission block 22 to move, the transmission block 22 is limited by the cooperation of the first guide rod 25 and the guide plate 26, so that the transmission block 22 can only move in the vertical direction during the movement, so as to avoid the transmission block 22 following the crank 21 to make an arc motion when the crank 21 drives the transmission block 22 to move, so that the clamping force applied to the surface of the welding wire can be vertically transmitted to the wire feeding wheel 14.

[0059] Next, please refer to Figure 5 The voltage regulating driving part 30 includes a voltage regulating motor 31, two driving rods 32, a suspension rod 33 and an elastic element 34. The voltage regulating motor 31 is assembled on one side of the positioning side plate 11 and is located between the cranks 21 in the two pressurizing parts 20. The two driving rods 32 are respectively fixed on the two output ends of the voltage regulating motor 31, and the driving rods 32 and the cranks 21 are threadedly connected. The suspension rod 33 is fixed to the upper end of the voltage regulating motor 31, and the suspension rod 33 and the guide plate 26 are slidably connected. The elastic element 34 is assembled between the suspension rod 33 and the guide plate 26.

[0060] Furthermore, the voltage regulating motor 31 is preferably a servo motor, which has the characteristics of good stability and response speed, and is convenient for quickly and accurately adjusting the clamping force applied to the surface of the welding wire.

[0061] It should be noted that a sleeve is rotatably connected to the upper end of the crank 21 , an internal thread is provided inside the sleeve, and the sleeve is adapted to the driving rod 32 , and the driving rod 32 and the crank 21 are connected via the sleeve thread.

[0062] In this embodiment, the voltage regulating motor 31 is started to rotate the output end of the voltage regulating motor 31. The voltage regulating motor 31 and the driving rod 32 are fixedly connected, so that the voltage regulating motor 31 drives the driving rod 32 to rotate, and the driving rod 32 drives the sleeve to move, thereby driving the crank 21 to rotate.

[0063] Please refer again Figure 5 The outer sides of the two driving rods 32 are both provided with male threads, and the thread rotation directions of the two male threads are opposite.

[0064] In this embodiment, the above-mentioned scheme is set up so that the cranks 21 in the two pressurizing parts 20 rotate in opposite directions. When the cranks 21 in the two pressurizing parts 20 rotate in the direction close to the voltage regulating motor 31, the clamping force applied to the surface of the welding wire increases. When the cranks 21 in the two pressurizing parts 20 rotate in the direction away from the voltage regulating motor 31, the clamping force applied to the surface of the welding wire decreases. At the same time, the cranks 21 will drive the sleeve to move synchronously when they rotate, and the movement of the sleeve is estimated to be an arc. Since the driving rod 32 is connected to the sleeve, the voltage regulating motor 31 and the driving rod 32 will move synchronously in the vertical direction. Due to the fixed connection between the voltage regulating motor 31 and the suspension rod 33 and the sliding connection between the suspension rod 33 and the guide plate 26, the voltage regulating motor 31 is guided in the vertical direction through the cooperation of the suspension rod 33 and the guide plate 26.

[0065] Please refer again Figures 6 to 8 As shown, the cleaning portion 40 includes a support seat 41, a cleaning motor 42, a first gear 43, a cleaning sleeve 44, a second gear 45 and a plurality of cleaning elements 46. The support seat 41 is fixed to one side of the positioning side plate 11, the cleaning motor 42 is fixed to the upper end of the support seat 41, and the cleaning motor 42 and the control box 19 are electrically connected through a wire, the first gear 43 is fixed to the output end of the cleaning motor 42, the cleaning sleeve 44 is rotatably connected to the inside of the support seat 41 through a ball bearing, a cleaning cavity is opened in the cleaning sleeve 44, and both ends of the cleaning sleeve 44 extend to the outside of the support seat 41, the second gear 45 is fixed to one end of the outside of the cleaning sleeve 44, and the first gear 43 and the second gear 45 are meshed and connected, and a plurality of cleaning elements 46 are detachably assembled on the side wall of the cleaning cavity.

[0066] Furthermore, a guide cone surface is provided at one end of the cleaning sleeve 44 near the welding wire reel 15, and the material of the cleaning element 46 has elasticity and decontamination performance.

[0067] Here, the cleaning element 46 and the cleaning sleeve 44 are plug-connected in the manner of a transition fit.

[0068] In this embodiment, after the welding wire reel 15 wound with the welding wire is assembled on the wire feeder body 10, the welding wire is passed through the cleaning cavity inside the cleaning sleeve 44 through the guide cone surface set at one end of the cleaning sleeve 44, and the welding wire is located between the multiple cleaning elements 46. The cleaning motor 42 is started to rotate the cleaning motor 42, and the cleaning motor 42 drives the first gear 43 to rotate through the fixed connection between the cleaning motor 42 and the first gear 43. The first gear 43 drives the second gear 45 to rotate through the meshing connection between the first gear 43 and the second gear 45. The second gear 45 drives the cleaning sleeve 44 to rotate through the fixed connection between the second gear 45 and the cleaning sleeve 44, and then drives the cleaning element 46 to rotate. The surface of the welding wire is cleaned by the cleaning element 46 to prevent the dirt on the surface of the welding wire from being driven into the inside of the wire guide hose, thereby increasing the resistance of the welding wire when moving inside the wire guide hose, further improving the stability and continuity of the welding wire transportation, and at the same time, it is also convenient to replace the cleaning element 46.

[0069] Please refer again Figure 7 and Figure 8 As shown, multiple cleaning elements 46 are in an inclined state, the distance from the end of the cleaning element 46 away from the wire entry nozzle 18 to the central axis of the cleaning sleeve 44 is recorded as L1, and the distance from the end of the cleaning element 46 close to the wire entry nozzle 18 to the central axis of the cleaning sleeve 44 is recorded as L2, L2>L1.

[0070] In this embodiment, the above-mentioned arrangement enables the cleaning element 46 to be in an inclined state, and the distance between the multiple cleaning elements 46 gradually decreases from the end close to the wire inlet nozzle 18 to the end far from the wire inlet nozzle 18. Through the cooperation of the multiple cleaning elements 46, welding wires of different diameters can be cleaned, thereby improving the applicability of the device.

[0071] Embodiment 2

[0072] Please refer again Fig. 9 , an intelligent welding control system, applicable to an intelligent welding control device of any one of the first embodiments, comprising:

[0073] A preprocessing module is used to obtain welding information and determine the target shielding gas according to the welding information. The welding information includes welding type, welding power and material of the welding target;

[0074] A data acquisition module, which is used to obtain operating parameters, including current, wire feeding speed and welding speed. The data acquisition module includes multiple sensors, which are respectively adapted to the power supply module, the gas supply module, the welding gun and the wire feeding module;

[0075] The control module is used to adjust the flow rate of the shielding gas according to the operating parameters and welding information.

[0076] Here, the power supply module is used to provide electrical energy, the gas supply module is used to transport protective gas and technical gas, the wire feeding module is used to transport welding wire, and the welding gun is used to weld the welding target.

[0077] In this embodiment, the unstable wire feeding speed will cause the flow rate of the shielding gas to change relative. If the wire feeding speed becomes slower, the flow rate of the shielding gas will become relatively larger, thereby increasing the generation of bubbles and pores in the weld and affecting the welding quality. If the wire feeding speed is faster, the flow rate of the shielding gas will become relatively smaller, thereby making the arc unstable and causing sputtering. The welding information and operating parameters are obtained respectively by the preprocessing module and the data acquisition module, so that the control module adjusts the flow rate of the shielding gas according to the operating parameters and the welding information.

[0078] In a specific embodiment, welding information such as welding type, welding power, welding target material, etc. is obtained through a preprocessing module to determine the target shielding gas, and operating parameters such as current, wire feeding speed, and welding speed are obtained through a data acquisition module. When any one or more operating parameters increase, the flow rate of the shielding gas is increased through a control module. When any one or more operating parameters become smaller, the flow rate of the shielding gas is reduced through a control module.
