Description

Technical Field

[0001] The utility model belongs to the technical field of welding machines, and particularly relates to an automatic welding machine. Background Art

[0002] With the development of modern industry, laser welding technology has been widely used in many fields such as metal processing, automobile manufacturing, electronic devices, and medical devices due to its advantages of high precision, high efficiency, and low heat-affected zone. However, traditional laser welding equipment often has problems such as complex structure, inconvenient operation, and poor flexibility, making it difficult to meet the welding requirements of complex workpieces.

[0003] Especially in an automated production line, higher requirements are put forward for the flexibility, accuracy, and stability of welding equipment. Most of the existing laser welding equipment uses a fixed workbench and welding head, making it difficult to achieve multi-station and multi-angle welding operations, and the welding process is easily affected by factors such as thermal deformation and vibration, resulting in unstable welding quality.

[0004] In addition, the heat generated during the laser welding process needs to be effectively controlled to prevent overheating of the laser emission module and the welding area, thereby affecting the welding effect and the service life of the equipment. Existing cooling systems often have problems such as uneven cooling effect and unreasonable layout of cooling components, making it difficult to meet the requirements of high-precision laser welding.

[0005] Therefore, it is very necessary to invent an automatic welding machine. Summary of the Utility Model

[0021] As shown in the attached Figure 1 to the attached Figure 3 figure:

[0022] The automatic welding machine provided by the utility model includes a workbench base 1, a water chiller 2, universal wheels 3, a welding frame 4, an observation window 5, a control panel 6, an alarm 7, welding jigs 8, a column 9, a Y-axis linear actuator 10, an X-axis linear actuator 11, a Z-axis linear actuator 12, a galvanometer laser welder 13 and a drag chain 14.

[0023] Embodiment 1:

[0024] Specifically, the water chiller 2 is connected to a dedicated cooling mechanism to ensure effective management of the heat generated during the laser welding process of the galvanometer laser welder 13. This cooling mechanism consists of several key components: the water tank is responsible for storing cooling water, the water pump drives the circulation of the cooling water, the water pipe serves as the transmission channel for the cooling water, and the joints are used for connecting various components. Particularly importantly, the cooling components are carefully arranged around the anode and cathode of the galvanometer laser welder 13 and the laser emission module. By means of direct contact or indirect cooling, they effectively absorb and carry away the heat in these high-temperature areas, ensuring the stable operation and long service life of the laser welder.

[0025] Specifically, as the cornerstone of the entire device, four universal wheels 3 are firmly installed at the four corners below the workbench base 1, endowing the device with good mobility and flexibility. To further enhance the stability of the device during static operation, telescopic legs are additionally installed on the outer sides of these universal wheels 3. When the device needs to be fixed in position for welding operations, the telescopic legs can be extended and contact the ground, jointly forming a stable support structure with the universal wheels 3. At the same time, the upper surface of the workbench base 1 is designed as a workbench for installing key components such as the welding jigs 8 and the column 9.

[0026] Specifically, the welding fixture 8 adopts a multi-station design, which means that multiple workpieces can be clamped simultaneously for welding, greatly improving the production efficiency. At least two welding fixtures 8 are ingeniously installed between the columns 9 and on the workbench of the workbench base 1, ensuring the stability and accuracy during the welding process. The multi-station design not only reduces the time for workpiece replacement but also enables the operator to handle multiple welding tasks simultaneously, enhancing the overall work efficiency. Meanwhile, the corresponding part fixtures can be replaced according to requirements to achieve the purpose of welding different parts.

[0027] Specifically, there are two groups of columns 9, each group containing two columns 9, which together form a stable support framework. On each group of columns 9, a Y-axis linear actuator 10 is fixedly installed, totaling two. The Y-axis linear actuator 10 is responsible for moving the galvanometer laser welder 13 in the horizontal direction. The X-axis linear actuator 11 and the Z-axis linear actuator 12 together form a vertical movement system, which are installed together and present a "cross" structure to achieve the precise positioning of the galvanometer laser welder 13 in three-dimensional space. It should be noted that these three linear actuators all adopt the type of screw linear actuator, which is known for its high stability and accuracy.

[0028] Specifically, there are two drag chains 14 in total. One of the drag chains 14 is arranged on one side of one of the X-axis linear actuators 11, and the other drag chain 14 is arranged on one side of the X-axis linear actuator 11 and the Z-axis linear actuator 12. After the X-axis linear actuator 11 and the Z-axis linear actuator 12 are installed together, they present a "cross" structure. The design of the drag chain 14 effectively manages the cables and signal lines between the linear actuators and other electrical components, preventing them from being entangled or damaged during the movement of the equipment.

[0029] Embodiment 2:

[0030] I. Working principle

[0031] Laser welder control: The galvanometer laser welder 13, as the core component of the welding operation, receives instructions through the computer control system to control the emission, focusing, and scanning path of the laser beam, achieving precise welding of the workpiece.

[0032] Three-dimensional space positioning: The Y-axis linear actuator 10, the X-axis linear actuator 11, and the Z-axis linear actuator 12 together form a three-dimensional space positioning system. The Y-axis actuator is responsible for the movement in the horizontal direction (front and back), the X-axis actuator (left and right) is responsible for the movement in the horizontal direction, and the Z-axis actuator is responsible for the lifting and lowering in the vertical direction. The coordinated work of the three ensures that the laser welding head can accurately move to the specified position according to the preset path.

[0033] Cooling System: The water chiller 2 is connected to a dedicated cooling mechanism to provide continuous cooling support for the galvanometer laser welder 13. The cooling mechanism effectively absorbs and removes the heat generated during the welding process through circulating cooling water, ensuring the stable operation and long lifespan of the laser welder.

[0034] Monitoring and Alarm: The observation window 5 allows the operator to monitor the welding process in real time to ensure the welding quality. The control panel 6 is used to input welding parameters and start / stop the welding operation. The alarm 7 will sound an alarm when the equipment malfunctions, reminding the operator to handle it in a timely manner.

[0035] Workpiece Clamping: The welding fixture 8 adopts a multi-station design and can clamp multiple workpieces for welding simultaneously. The stability and precision of the fixture ensure the stability and accuracy during the welding process. When changing products, the corresponding welding fixture 8 needs to be replaced.

[0036] II. Workflow

[0037] Preparation Stage: Place the workpiece to be welded on the welding fixture 8 and adjust the position and angle of the fixture as needed. Meanwhile, input welding parameters such as laser power, welding speed, scanning path, etc. through the control panel 6.

[0038] Startup and Positioning: Start the automatic welding machine, and the Y-axis linear actuator 10, X-axis linear actuator 11, and Z-axis linear actuator 12 start to work together to move the galvanometer laser welder 13 to the preset starting position.

[0039] Welding Operation: Under the command of the control system, the galvanometer laser welder 13 starts to emit laser beams and performs welding operations according to the preset scanning path. Meanwhile, the cooling system keeps working to ensure the stable operation of the laser welder.

[0040] Monitoring and Adjustment: The operator monitors the welding process in real time through the observation window 5 and can fine-tune the welding parameters through the control panel 6 if necessary.

[0041] Completion and Cleaning: After the welding operation is completed, the automatic welding machine stops working automatically. The operator can remove the welded workpiece from the welding fixture 8 and perform necessary cleaning and tidying work.

[0042] Abnormal Handling: If the equipment malfunctions during operation (such as overheating, mechanical failure, etc.), the alarm 7 will sound an alarm, and the operator needs to immediately stop the machine for inspection and handle the abnormal problems.

[0043] Using the technical solution described in the present utility model, or a person skilled in the art designing a similar technical solution inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
