Description

Technical Field

[0001] This utility model relates to the field of laser welding, specifically to integrated laser welding equipment. Background Technology

[0002] Laser welding technology is a fusion welding technology that uses a high-energy-density laser beam as a heat source. It achieves connection by melting materials through a focused laser beam. Its principle is based on the generation of in-phase light waves by stimulated emission of a medium, forming a high-energy laser beam. This technology originated with the advent of the ruby ​​pulsed laser in 1960. After the power of CO2 and YAG lasers increased in the 1970s, it was gradually applied to thin sheet alloys and precision machining.

[0003] Currently, traditional laser welding equipment often encounters laser overheating issues, requiring the equipment to cool down before resuming operation. This reduces production efficiency, and if cooling is not performed promptly, the welding gun may be damaged and require replacement, increasing costs. Therefore, this invention provides an integrated laser welding device with a cooling system. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an integrated laser welding equipment to solve the technical problem of excessively high welding gun temperature in laser welding equipment, which reduces production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated laser welding device, comprising a welding gun, a cooling device on the right side of the welding gun for cooling the welding gun, a protective shell, an infrared sensor on one side of the protective shell, a control module on the left side of the infrared sensor, a pneumatic nozzle at the bottom of the cooling device, and a pneumatic atomizing device below the pneumatic nozzle.

[0006] By adopting the above technical solution, the integrated layout of the welding gun and cooling equipment significantly optimizes the equipment's spatial structure, making the operation flow of the laser welding equipment more compact and efficient. Operators can switch between welding and cooling processes without having to move the equipment over long distances. Simultaneously, the physical isolation of the cooling zone by the protective shell effectively reduces interference from the external environment on the cooling process, ensuring the stability of the media sprayed by the pneumatic nozzle. Furthermore, the coordinated deployment of the infrared sensor and control module provides underlying support for automated triggering, enabling the welding gun to autonomously initiate subsequent actions after entering the protective shell.

[0007] Furthermore, the internal device of the protective housing includes a sensor probe, which is connected to an infrared sensor.

[0008] By adopting the above technical solution, the sensor probe added inside the protective shell significantly improves the accuracy and anti-interference capability of welding gun position detection, avoids misjudgments caused by visual obstruction or ambient light, and ensures that the cooling process only starts after the gun body is accurately positioned. At the same time, the hard connection between the sensor probe and the infrared sensor enhances the real-time performance and reliability of signal transmission.

[0009] Furthermore, a cooling tank is provided at the bottom of the cooling device, and a water level sensor is provided on the surface of the cooling tank to detect the current remaining coolant. The infrared sensor is model GP2Y0A41SK0F, and the water level sensor is model Siemens HydroRanger.

[0010] By adopting the above technical solution, the bottom integrated design of the cooling tank optimizes the coolant delivery efficiency by relying on gravitational potential energy, reduces the mechanical delivery pressure on the connecting rod, and the water level sensor installed on its surface can continuously monitor changes in the remaining coolant level, preventing the risk of cooling interruption or system idling due to medium depletion. Meanwhile, the water level sensor, model "Siemens HydroRanger," features high resolution and corrosion resistance, enabling stable operation in low-temperature coolant environments.

[0011] Furthermore, an alarm is provided on one side of the water level sensor to warn that the coolant inside the cooling tank has dropped to a preset water level.

[0012] By adopting the above technical solution, the linkage configuration of the water level sensor and the alarm establishes a dual safety mechanism. When the liquid level in the cooling tank is lower than the preset safety threshold, the water level sensor immediately activates the adjacent alarm to output an audible and visual warning signal, enabling the operator to quickly respond to the coolant replenishment needs. At the same time, the physical proximity of the alarms effectively shortens the signal transmission path, avoids information delays caused by circuit delays, and ensures that maintenance personnel can intervene in a timely manner to replenish the coolant.

[0013] Furthermore, the pneumatic atomizing device is movably connected to the cooling tank via a connecting rod, and the cooling tank delivers coolant into the pneumatic atomizing device via the connecting rod.

[0014] By adopting the above technical solution, the movable connecting rod forms a flexible delivery channel between the cooling tank and the pneumatic atomizing device, allowing the equipment to maintain stable coolant delivery under vibration conditions and avoiding the risk of seal failure or pipeline rupture caused by mechanical stress in rigid connections. At the same time, the adjustable nature of the movable connecting rod allows maintenance personnel to quickly disassemble the cooling tank for cleaning or replacement, significantly simplifying coolant replenishment and equipment maintenance procedures and reducing downtime for maintenance.

[0015] Furthermore, the pneumatic atomizing device can convert the coolant into gas and deliver it to the pneumatic nozzle to cool the welding gun.

[0016] By adopting the above technical solution, the gas phase conversion function of the pneumatic atomizing device atomizes the liquid coolant into an ultra-low temperature gaseous medium. Compared with traditional liquid cooling contact solutions, the atomized gas can fully penetrate the complex structure of the welding torch surface, achieving three-dimensional heat exchange. At the same time, the gas phase change process absorbs a large amount of latent heat, rapidly reducing the surface temperature the instant it contacts the high-temperature area of ​​the welding torch; this physical characteristic enables a higher order of cooling efficiency with the same amount of coolant.

[0017] Furthermore, the pneumatic nozzle can change the air output per second via a control unit.

[0018] By adopting the above technical solution, the adjustable pneumatic nozzle's air output control capability gives the cooling equipment adaptive characteristics to cope with different working conditions. For example, a small flow rate is used to maintain cooling for welding guns with slight temperature rise, while a large flow rate rapid cooling mode is used for high-temperature gun bodies after continuous welding, avoiding the waste of resources or the risk of insufficient cooling caused by a one-size-fits-all cooling solution.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. When the welding gun enters the protective shell, the sensor probe and the infrared sensor work together to trigger the control module, realizing fully automatic cooling start and stop. No manual intervention is required in the operation process, eliminating efficiency loss and false trigger risk caused by human operation delay. At the same time, the protective shell provides a physical isolation barrier for the cooling process, preventing external contaminants from contacting the pneumatic nozzle and the core components of the welding gun, and maintaining the cleanliness of the system.

[0021] 2. This utility model uses a pneumatic atomizing device to obtain liquid coolant from the cooling tank through a connecting rod and convert it into low-temperature aerosol. This aerosol is then directionally sprayed onto the surface of the welding gun through a pneumatic nozzle. Utilizing the principle of phase change heat absorption, it achieves efficient heat exchange, significantly shortening the cooling time. At the same time, the control unit dynamically adjusts the air output of the pneumatic nozzle to adapt to the cooling requirements under different welding intensities, avoiding over-cooling or under-cooling. Meanwhile, the water level sensor monitors the liquid level in the cooling tank in real time, and the linked alarm actively sounds when the remaining liquid is insufficient. This dual protection ensures the continuity of coolant supply and prevents the equipment from being damaged by dry burning. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] Integrated laser welding equipment, such as Figure 1-4 As shown, the laser welding equipment includes a laser welding device 1, which includes a welding torch 2. A cooling device 3 is located on the right side of the welding torch 2 to cool it down. The cooling device 3 includes a protective shell 4, an infrared sensor 5 is located on one side of the protective shell 4, a control module 6 is located on the left side of the infrared sensor 5, and a pneumatic nozzle 12 is located at the bottom of the cooling device 3. A pneumatic atomizing device 7 is located below the pneumatic nozzle 12. The integrated layout of the welding torch 2 and the cooling device 3 significantly optimizes the spatial structure of the equipment, making the operation flow of the laser welding equipment 1 more compact and efficient. Operators can switch between welding and cooling processes without moving equipment over long distances. Meanwhile, the physical isolation of the cooling zone by the protective shell 4 effectively reduces the interference of the external environment on the cooling process and ensures the stability of the spray medium from the pneumatic nozzle 12. The coordinated deployment of the infrared sensor 5 and the control module 6 provides underlying support for automated triggering, enabling the welding gun 2 to autonomously start subsequent actions after entering the protective shell 4, greatly reducing manual operation. The design of the pneumatic atomizing device 7 located below the pneumatic nozzle 12 can minimize the cooling medium delivery path and improve response speed and heat exchange efficiency.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4The protective housing 4 contains a sensor probe 13, which is connected to an infrared sensor 5. The sensor probe 13, added inside the protective housing 4, significantly improves the accuracy and anti-interference capability of the welding gun 2 position detection, avoids misjudgment caused by visual obstruction or ambient light, and ensures that the cooling process is only started after the gun body is accurately positioned. At the same time, the hard connection between the sensor probe 13 and the infrared sensor 5 enhances the real-time performance and reliability of signal transmission, avoids system response delay caused by wireless signal latency, and thus triggers the control module 6 to issue a command as soon as the welding gun 2 enters the protective housing 4, significantly shortening the cooling preparation cycle.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The cooling device 3 has a cooling tank 9 at its bottom. A water level sensor 10 is installed on the surface of the cooling tank 9 to detect the current remaining coolant. The infrared sensor 5 is model GP2Y0A41SK0F, and the water level sensor 10 is model Siemens HydroRanger. The bottom integrated design of the cooling tank 9 optimizes the coolant delivery efficiency by relying on gravitational potential energy, reducing the mechanical delivery pressure on the connecting rod 8. The water level sensor 10 on its surface can continuously monitor the change in the remaining coolant, preventing the risk of cooling interruption or system idling due to medium depletion. At the same time, the water level sensor 10, model "Siemens HydroRanger", has high resolution and corrosion resistance, and can operate stably in the low temperature environment of the coolant. The infrared sensor 5, model "GP2Y0A41SK0F", has both short-range detection accuracy and anti-thermal radiation interference capability, ensuring that the high temperature surface of the welding gun 2 will not interfere with the positioning signal.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An alarm 11 is provided on one side of the water level sensor 10 to warn that the coolant inside the cooling tank 9 has dropped to a preset water level. The linkage configuration of the water level sensor 10 and the alarm 11 establishes a dual safety mechanism. When the liquid level in the cooling tank 9 is lower than the preset safety threshold, the water level sensor 10 immediately activates the adjacent alarm 11 to output an audible and visual warning signal, enabling the operator to quickly respond to the coolant replenishment needs. At the same time, the physical proximity of the alarm 11 effectively shortens the signal transmission path and avoids information delay due to circuit delay, ensuring that maintenance personnel can intervene in time to replenish coolant. This combined design upgrades passive monitoring to active early warning, significantly reducing the risk of overheating damage to the welding torch 2 caused by cooling interruption.

[0033] See Figure 1 , Figure 2 , Figure 3, Figure 4 The pneumatic atomizing device 7 is movably connected to the cooling tank 9 via a connecting rod 8. The cooling tank 9 delivers coolant to the pneumatic atomizing device 7 via the connecting rod 8. The movably connected connecting rod 8 forms a flexible delivery channel between the cooling tank 9 and the pneumatic atomizing device 7, allowing the equipment to maintain stable coolant delivery under vibration conditions. This avoids the risk of seal failure or pipeline rupture caused by mechanical stress in rigid connections. At the same time, the adjustable characteristics of the movable connecting rod 8 allow maintenance personnel to quickly disassemble the cooling tank 9 for cleaning or replacement, greatly simplifying the coolant replenishment and equipment maintenance process and reducing downtime for maintenance. The core value of its structural design lies in balancing delivery efficiency and system maintainability, extending the overall service life of the cooling equipment 3.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The pneumatic atomizing device 7 can convert the coolant into gas and deliver it to the pneumatic nozzle 12 to cool the welding gun 2. The gas phase conversion function of the pneumatic atomizing device 7 atomizes the liquid coolant into an ultra-low temperature gaseous medium. Compared with the traditional liquid cooling contact solution, the atomized gas can fully penetrate the complex surface structure of the welding gun 2, such as the gap of the gun head or the periphery of the weld focusing lens, to achieve three-dimensional heat exchange. At the same time, the gas phase change process absorbs a large amount of latent heat, which rapidly reduces the surface temperature at the moment of contact with the high temperature area of ​​the welding gun 2. This physical characteristic enables the same amount of coolant to achieve higher cooling efficiency, while avoiding the risk of optical component contamination caused by liquid splashing, thus improving the system reliability from both efficiency and cleanliness perspectives.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The pneumatic nozzle 12 can change the air output per second through the control unit. The adjustable air output control capability of the pneumatic nozzle 12 gives the cooling device 3 adaptive characteristics to cope with different working conditions. For example, a small flow rate is used to maintain cooling for the welding gun 2 with slight temperature rise, while a large flow rate rapid cooling mode is used for the high-temperature gun body after continuous welding. This avoids the waste of resources or the risk of insufficient cooling caused by a one-size-fits-all cooling solution. At the same time, the real-time adjustment algorithm of the control unit can dynamically match the welding process parameters and optimize the coolant consumption while ensuring the safe temperature of the welding gun 2, which significantly reduces long-term operating costs and maintenance frequency.

[0036] The implementation principle of this embodiment is as follows: When the welding torch 2 needs to be cooled, the operator moves it into the area inside the protective shell 4 of the cooling equipment 3. At this time, the sensor probe 13 installed inside the protective shell 4 will detect the presence of the welding torch 2 and transmit the signal to the infrared sensor 5 connected to it. The infrared sensor 5 then sends a detection signal to the control module 6. After receiving the signal, the control module 6 starts the cooling process: First, the control cooling tank 9 delivers liquid coolant to the pneumatic atomizing device 7 located above it through the movable connecting rod 8. Then, the pneumatic atomizing device 7 atomizes the input liquid coolant. The cooling gas is converted into a low-temperature gaseous medium. The control module 6 sends a start command to the pneumatic nozzle 12. The atomized cooling gas is precisely sprayed onto the surface of the welding gun 2 through the pneumatic nozzle 12 for rapid heat exchange and cooling. During this process, the control module 6 can adjust the gas output per second of the pneumatic nozzle 12 in real time through the control unit to adapt to different cooling requirements. The water level sensor 10 installed on the surface of the cooling tank 9 continuously monitors the remaining coolant in the tank. If the water level sensor 10 detects that the coolant level has dropped to the preset minimum safety value, it immediately triggers the adjacent alarm 11 to issue a warning signal, prompting the operator to replenish the coolant in time.
