Description

Technical Field

[0001] The invention relates to the technical field of automated welding, and in particular to an automated welding device of an intelligent welding robot. Background Art

[0002] Welding is a manufacturing process that uses heating, pressurization or a combination of both to achieve atomic bonding between the surfaces of two or more metal or non-metal materials to form a permanent connection. Welding is a highly technical job. Whether in manufacturing, construction or other industries, the quality of welding directly affects the performance and safety of the product. Especially in the field of automated welding, automated welding technology can significantly improve production efficiency and welding quality, reduce costs, improve safety, and increase flexibility. It has a wide range of applications in the field of industrial manufacturing.

[0003] Modern automation technology is mainly realized by computer control technology. Welding production automation is the development direction of welding structure production technology. Modern welding automation technology is to develop intelligent welding equipment based on high-performance microcomputer wave-controlled welding power supply, develop flexible welding workstations and welding production lines based on existing welding robots, and develop and apply microcomputer automation control technology in welding equipment, such as CNC welding power supply, intelligent welding machine, fully automatic special welding machine and flexible welding robot workstation. The role of microcomputer control system in various automatic welding and cutting equipment is not only to control various welding parameters, but also to be able to automatically coordinate the actions of various components of the complete set of welding equipment to achieve unmanned operation, that is, to achieve numerical control, automation and intelligence of welding production.

[0004] When the automatic welding device is working, the humidity and cleanliness of the working environment will have a direct impact on the welding quality and the stability of the welding process. For workpieces with high humidity or in a welding environment with high humidity, moisture will conduct electricity, which will affect the stability of the arc generated during welding, and easily increase the spatter during welding, resulting in a decrease in welding quality. The presence of impurities will also affect the stability of the arc, causing the current fluctuations during welding to become violent and further increase the spatter, which will easily form a vicious circle during the welding process. In addition, during the welding process, a large amount of smoke and other harmful gases will be generated at the welding point. If these gases are not handled in time, they will accumulate and the concentration will increase, eventually forming a harmful environment. To this end, we propose an intelligent welding robot automatic welding device. Summary of the invention

[0016] The present invention has the following beneficial effects: 1. The present invention uses a fan to guide high-temperature gas from the gas outlet pipe into the dehumidification pipe at high speed, and blows the high-speed gas toward the workpiece through the dehumidification pipe to clean the surface of the workpiece, remove dust and impurities on the surface of the workpiece, and can prevent dust and impurities from melting into the weld during the welding process of the welding head, resulting in reduced welding quality, and also prevent the arc stability from being affected by excessive impurities during welding, resulting in violent current fluctuations during welding and increased spatter.

[0017] 2. The present invention heats the workpiece and its surroundings by blowing high-temperature gas toward the workpiece, thereby reducing the humidity of the workpiece and its surroundings, preventing the high humidity in the welding environment from affecting the stability of the arc, and avoiding arc instability, which leads to an increase in spatter generated during welding and a decrease in welding quality; it prevents excessive humidity from increasing the hydrogen content in the weld, which easily causes hydrogen embrittlement, thereby improving the toughness and crack resistance of the weld.

[0018] 3. The present invention absorbs the gas near the workpiece through the fan, air inlet pipe and dust hopper, which can not only quickly cool the workpiece welding point, but also dispel the smoke and other harmful gases generated during the welding process. With the high-speed gas blown out by the dehumidification pipe, it can form a good ventilation effect to prevent smoke and other harmful gases from gathering to form a harmful environment and affect human health. The fan absorbs the high-temperature gas near the workpiece, and the filter tube filters out impurities in the gas. The high-temperature gas will enter the dehumidification pipe through the fan and the air outlet pipe, which can play a stronger dehumidification role on the workpiece and greatly improve the dehumidification capacity of the workpiece.

[0019] 4. The dust hopper of the present invention can block the spatters generated by welding, and by intercepting the spatters, it is convenient to adsorb the spatters. The dust hopper allows the gas near the welding head to be more evenly sucked into the air intake pipe, and the high-temperature gas generated during the welding process will be more absorbed and utilized. At the same time, an orderly airflow is formed near the welding head, which is convenient for heat dissipation of the welding head, avoiding overheating of the welding head due to long-term use, and facilitating the service life of the welding head.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0025] See also Figure 1 - Fig.10 As shown, an intelligent welding robot automatic welding device comprises a base 1, a mechanical arm 2 fixedly arranged on one side above the base 1, and a welding head 3 fixedly arranged at the output end of the mechanical arm 2, a connecting seat 4 is fixedly installed at the output end of the mechanical arm 2, a dust collecting hopper 5 is fixedly installed at the end of the connecting seat 4, the welding head 3 is fixedly connected to the inside of one end of the connecting seat 4, and the welding head 3 is located in the middle of the inner side of the dust collecting hopper 5, a dust collecting component 6 is fixedly installed on the other side above the base 1, and a dehumidification pipe 7 is arranged on the side of the connecting seat 4, and the dehumidification pipe 7 rotates on the side of the connecting seat 4; in the welding operation, the mechanical arm 2 is first used to transport the welding head 3 to the position where the workpiece is to be welded. Then adjust the dehumidification pipe 7 so that the dehumidification pipe 7 is always located in front of the moving path of the welding head 3. Then start the dust collecting component 6, the dust collecting component 6 absorbs the gas near the welding head 3, and discharges the gas from the dehumidification pipe 7. Finally, use the welding head 3 to perform welding work. The connecting seat 4 facilitates the installation and fixation of the welding head 3 on the mechanical arm 2. The rotation center axis of the dehumidification tube 7 and the center axis of the dust collecting hopper 5 are on the same straight line.

[0026] The dust collection assembly 6 includes a dust storage box 61 fixedly installed on the other side above the base 1, a fan 62 fixedly installed on the upper part of the dust storage box 61, an air inlet pipe 63 fixedly installed in the middle of the side of the dust storage box 61, an air outlet pipe 64 fixedly installed at the upper end of the side of the dust storage box 61, and a filter tube 65 fixedly installed at the air inlet end of the fan 62. The air inlet end of the air inlet pipe 63 is connected to the air outlet end of the dust collecting hopper 5, the air inlet end of the air outlet pipe 64 is connected to the air outlet end of the fan 62, and the air outlet end of the air outlet pipe 64 is connected to the air inlet end of the dehumidification pipe 7. The fan 62 absorbs the air inside the dust storage box 61 to continuously cool the motor in the fan 62 and reuse the high temperature generated by the motor.

[0027] In order to solve the problem of spatter generated during welding and affecting welding, based on the present device, before using the welding head 3 for welding, the motor of the fan 62 generates heat during operation, forming a high-temperature environment in the dust storage box 61. The fan 62 introduces the high-temperature gas into the dehumidification pipe 7 at high speed through the outlet pipe 64, and blows the high-speed gas to the workpiece through the dehumidification pipe 7 to clean the surface of the workpiece, remove dust and impurities on the surface of the workpiece, and avoid dust and impurities from melting into the weld during the welding process of the welding head 3, resulting in reduced welding quality, and also avoid affecting the stability of the arc due to excessive impurities in welding, resulting in drastic current fluctuations during welding and increasing spatter.

[0028] In order to solve the problem that the high humidity of the workpiece to be welded and the welding environment will affect the welding quality, based on this device, when the high-temperature gas is blown to the workpiece, the workpiece and the surrounding environment are heated, the humidity of the workpiece and the surrounding environment is reduced, and the high humidity of the welding environment is prevented from affecting the stability of the arc, and the arc is prevented from being unstable, resulting in an increase in spatter generated by welding and a decrease in welding quality; the environmental humidity is prevented from being too high, resulting in an increase in the hydrogen content in the weld, which is easy to cause hydrogen embrittlement, thereby improving the toughness and crack resistance of the weld.

[0029] In order to solve the problem that smoke and other harmful gases gather during welding and form a harmful environment, during welding, the fan 62 absorbs the gas near the workpiece through the air inlet pipe 63 and the dust collector 5, which can not only quickly cool the weld point of the workpiece, but also disperse the smoke and other harmful gases generated during welding. Combined with the high-speed gas blown out by the dehumidification pipe 7, a good ventilation effect can be formed to prevent smoke and other harmful gases from gathering to form a harmful environment and affect human health.

[0030] At the same time, the fan 62 absorbs the high-temperature gas near the workpiece, and after the filter tube 65 filters out impurities in the gas, the high-temperature gas will enter the dehumidification pipe 7 through the fan 62 and the outlet pipe 64, which can have a stronger dehumidification effect on the workpiece and greatly improve the dehumidification capacity of the workpiece.

[0031] Moreover, the dust hopper 5 can block the spatters generated by welding, and can be easily adsorbed by intercepting the spatters. The dust hopper 5 can make the gas near the welding head 3 be more evenly sucked into the air inlet pipe 63, and the high-temperature gas generated during the welding process will be more absorbed and utilized. At the same time, an orderly airflow is formed near the welding head 3, which is convenient for heat dissipation of the welding head 3, avoiding overheating of the welding head 3 due to long-term use, and facilitating the service life of the welding head 3.

[0032] Based on this device, by utilizing the heat generated by welding and the heat generated by the motor of the fan 62 during operation to dehumidify the workpiece and the welding environment, energy can be saved and energy utilization can be improved.

A positioning seat 9 for installing a filter tube 65 is fixedly provided at the air inlet end of the casing 621, and the filter tube 65 and the positioning seat 9 are threadedly connected.

[0036] In order to prevent the motor in the fan 62 from generating a large amount of heat during long-term welding work, which will cause the motor power consumption to increase and easily burn out, based on the present design, the airflow formed during the operation of the impeller 622 is used to dissipate the heat of the drive motor 623, which can prevent the drive motor 623 from overheating and ensure that the working environment temperature of the drive motor 623 will not be too high, thereby ensuring that the drive motor 623 is always in a good working condition. At the same time, the heat generated by the drive motor 623 can be recycled, thereby improving the device's ability to dehumidify the workpiece and the welding environment.

By adjusting the dehumidification pipe 7, it is convenient to always make the dehumidification pipe 7 located in front of the moving path of the welding head 3, so that the high-temperature gas discharged by the dehumidification pipe 7 can dehumidify the workpiece and the welding environment in advance.
