Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, specifically a horizontal and vertical two-in-one laser welding equipment. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source to melt and join workpieces. It is widely used in many fields such as electronics and machinery manufacturing. However, there are some common problems in the laser welding process. On the one hand, the heat and slag generated during welding (such as metal spatter) pose a threat to the safety of operators and can easily contaminate equipment and the working environment, affecting the service life of equipment and the quality of subsequent processing. On the other hand, traditional laser welding equipment is inconvenient to adjust the position of the welding head when welding workpieces of different shapes and sizes, making precise positioning difficult and resulting in unstable welding quality and low production efficiency.

[0003] According to publication number CN220761345U, this laser welding equipment adjusts the height of the welding machine through a first adjustment mechanism so that the welding point of the welding head can reach the conveying mechanism; the height of the vision positioning component is adjusted by utilizing the relative position of the vertical strip holes and the horizontal bar mounting holes on the mounting plate to obtain a clear image of the product posture; after the vision positioning component obtains the product posture, it transmits it to the control system, and controls the welding machine to weld after confirming that the posture is good; the air knife component performs dust removal work on the generated powder during the welding process.

[0004] While it can solve some problems in the welding process to a certain extent, most of the equipment can only be designed vertically or horizontally and can only weld a certain type of workpiece.

[0005] Therefore, in order to address the shortcomings of the existing equipment, a horizontal and vertical combined laser welding device was proposed. Utility Model Content

[0030] The bottom of the vertical frame 5 is provided with a base plate 27, the top of the base plate 27 is provided with a placement rack 26, the top of the placement rack 26 is provided with a pipe body 24, the bottom of the base plate 27 is provided with a support column 23, and the top of the machine body 7 is provided with an opening 25 corresponding to the surface of the base plate 27.

[0031] A protective mechanism is installed on the top of the machine body 7 away from the vertical frame 5. The protective mechanism is used to prevent the laser gun head locking head 9 from generating a large amount of slag during operation.

[0032] The protective mechanism includes a motor assembly 6, a light shield 8, a support rod 14, a splash guard 15, a table slot 12, a rotating shaft 13, a gear 16, a rack 17, a movable rod 18, a limiting shaft 19, a slider 20, and a spring 21. A motor assembly 6 is installed on the top of the machine body 7, away from the horizontal frame 1. A rotating shaft 13 is installed on one side of the motor assembly 6. A gear 16 is installed on one side of the rotating shaft 13. A rack 17 is installed on the top of the gear 16. A support rod 14 is installed at one end of the rack 17. A light shield 8 is installed outside the support rod 14. A splash guard 15 is installed at the upper end of the light shield 8. A movable rod 18 is installed at the other end of the rack 17. A slider 20 is installed at the bottom of the movable rod 18. A limiting shaft 19 is horizontally inserted through the inner side of the slider 20. A spring 21 is installed on one side of the slider 20 and is sleeved on the outside of the limiting shaft 19.

[0033] The remaining applications include the use of this horizontal and vertical dual-purpose laser welding equipment in the welding of small metal parts for electronic devices.

[0034] Firstly, for the horizontal welding mode, small metal parts in electronic devices, such as connectors for the metal frame of mobile phones, are small in size and have relatively regular shapes. These small metal parts are placed on the horizontal frame 1. Since the guide rail 2 can move laterally outside the horizontal rail 22, and the control block 10 carrying the welding head 11 is set outside the guide rail 2, the control block 10 is operated by a high-precision control system. The welding head 11 can move extremely accurately along the guide rail 2 within the lateral range defined by the horizontal rail 22. For example, when welding the connectors for the metal frame of mobile phones, the welding head 11 can move according to a preset precision straight line trajectory to achieve precise welding of the connectors, ensure the accuracy of the welding position, and meet the high welding precision requirements of small electronic device components.

[0035] Next, for the vertical welding mode, taking the welding of cylindrical metal tube components in electronic devices as an example, the cylindrical metal tube to be welded is placed on the placement rack 26. The placement rack 26 is fixedly connected to the base plate 27, and the base plate 27 can rotate on the top of the column 23. By rotating the base plate 27, the angle of the metal tube can be adjusted very flexibly so that the part to be welded is accurately aligned with the clamping head 9. When the adjustment is in place, the clamping head 9 firmly clamps and fixes the metal tube to ensure that the metal tube will not move at all during the welding process. At this time, the control block 10 drives the welding head 11 to move to the appropriate position. The welding head 11 emits a laser beam and performs a circular welding operation along the welding part of the metal tube to achieve a tight welding of the metal tube and ensure its sealing and structural stability.

[0036] Furthermore, to further optimize the welding effect, the welding head 11 can be replaced with a new type of laser welding head 11 with intelligent zoom function. This new type of welding head 11 can automatically adjust the focal length and energy density of the laser beam according to factors such as the material and thickness of the welding parts. When welding small metal parts of electronic devices, when encountering thinner metal sheets, the welding head 11 automatically reduces the focal length and increases the energy density to achieve fast and high-quality welding. When welding thicker metal tubes, it automatically increases the focal length and distributes energy evenly to ensure welding depth and strength, thereby further improving the applicability and welding quality of the equipment in welding electronic device parts. At the same time, the light shield 8 in the protective mechanism can be made of a new material with higher absorption rate, which can better absorb the strong light generated during the welding process and reduce damage to the operator's eyes. In addition, the material of the anti-splatter plate 15 is replaced with a higher strength and wear-resistant material to extend its service life and better block welding slag splashes, protecting the working environment and other parts of the equipment.

[0037] In the field of automotive parts welding, the horizontal welding of this combined horizontal and vertical laser welding equipment is applied to many long strip metal components that need to be welded in the car body frame. These long strip metal components are placed on the horizontal frame 1. By utilizing the lateral movement characteristics of the guide rail 2 outside the horizontal rail 22 and the precise control of the welding head 11 by the control block 10, the welding head 11 can perform long-distance, high-precision straight-line welding or complex curve welding along the length of the component. For example, when welding the reinforcing beam of the car body side panel, the welding head 11 can move according to the preset curved trajectory, perfectly fit the shape of the reinforcing beam, achieve a firm and uniform welding, and enhance the overall strength and stability of the car body frame.

[0038] In vertical welding, automotive exhaust pipes and other pipe components need to be welded. The exhaust pipe is placed on the mounting rack 26, and the angle of the exhaust pipe is adjusted by rotating the base plate 27 to ensure that the part to be welded is precisely aligned with the clamping head 9. After the clamping head 9 clamps and fixes the exhaust pipe, the control block 10 drives the welding head 11 to move to the appropriate position for welding. At this time, the welding head 11 emits a laser beam to perform longitudinal welding on the exhaust pipe, ensuring the sealing and connection strength of the exhaust pipe and meeting the working requirements of the automotive exhaust system.

[0039] To further optimize the equipment's performance in automotive parts welding, the control system can be upgraded by adopting more advanced sensor technology to monitor parameters such as temperature and pressure during the welding process in real time and feed these parameters back to the control system. When the welding temperature is too high, the control system automatically adjusts the laser emission power of the welding head 11 to prevent parts from deforming due to overheating. When the welding pressure is abnormal, the clamping force of the clamping head 9 is adjusted in time to ensure welding quality. At the same time, the guide rail 2 and the horizontal rail 22 are replaced with high-precision linear guide rail 2 to improve the smoothness and accuracy of the movement of the welding head 11 and reduce errors during the movement process, thereby making the welding quality more stable and reliable. For the protective mechanism, an intelligent speed adjustment device is added to the motor assembly 6 to automatically adjust the moving speed of the rack 17 according to the actual welding situation, improving work efficiency while ensuring the protective effect. Furthermore, a self-cleaning coating is added to the light shield 8 and the splash guard 15 to make it easier for slag adhering to the welding process to fall off, reducing the frequency of manual cleaning and further improving the practicality of the equipment.

[0040] Working principle: When using this horizontal and vertical combined laser welding equipment, the main structure is composed of a horizontal frame 1 and an additional body 7. The two work together to provide a stable support platform for welding work. The guide rails 2 and horizontal rails 22 provide a guiding path for the movement of the welding head 11, allowing the welding head 11 to move flexibly within a specific area. The vertical frame 5 and its auxiliary components provide the necessary working position for vertical welding operations.

[0041] The guide rail 2 can move laterally outside the horizontal rail 22. The control block 10 is equipped with the welding head 11 and is located outside the guide rail 2. By controlling the control block 10 through the control system, the welding head 11 can move flexibly along the guide rail 2 within the lateral range defined by the horizontal rail 22. This movement method allows the welding head 11 to be accurately positioned above the horizontal frame 1 to weld the workpiece.

[0042] When the welding head 11 moves to the designated position, it emits a laser beam to perform welding operations on the workpiece. In the horizontal welding scenario, it can perform welding operations on various workpieces placed on the horizontal frame 1 with different trajectories such as straight lines and curves, to meet the welding needs of workpieces of different shapes and sizes.

[0043] The vertical base 3, the fixed base 4, and the clamping head 9 at the top of the vertical frame 5 work together to fix the workpiece. The pipe body 24 that needs to be vertically welded is placed on the placement frame 26. The placement frame 26 is fixedly connected to the base plate 27. The base plate 27 can rotate on the top of the column 23. By rotating the base plate 27, the angle of the pipe body 24 can be adjusted so that the part to be welded is accurately aligned with the clamping head 9. When the adjustment is in place, the clamping head 9 clamps and fixes the pipe body 24 to ensure that the workpiece will not be displaced during the welding process.

[0044] After the workpiece is fixed, the control block 10 drives the welding head 11 to move to a suitable position and performs vertical welding on the fixed pipe body 24. The welding head 11 emits a laser beam and welds along the welding part of the pipe body 24 to achieve longitudinal or circumferential welding of the pipe.

[0045] Throughout the welding process, the horizontal frame 1, the additional machine body 7, the guide rail 2, the horizontal rail 22, the control block 10, the welding head 11, the vertical frame 5, the vertical base 3, the fixed base 4, the clamping head 9, the base plate 27, the placement rack 26, the pipe body 24, and the support column 23 work together. First, depending on the type of workpiece and the welding requirements, the horizontal or vertical welding mode is selected. If it is horizontal welding, the workpiece is placed on the horizontal frame 1, and the welding head 11 is moved and welded. If it is vertical welding, the pipe body 24 is fixed, and then the position of the welding head 11 is adjusted for welding, thus realizing a high-efficiency laser welding operation that combines horizontal and vertical modes.

[0046] During the welding process, the protective mechanism comes into play. The motor assembly 6 is activated, which drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the gear 16 to rotate. The gear 16 meshes with the rack 17, causing the rack 17 to move horizontally. The rack 17 drives the support rod 14 to move closer to the position of the clamping head 9. The light shield 8 and the splash shield 15 on the outside of the support rod 14 shield the working area of ​​the clamping head 9, reducing the heat and slag generated during operation. When the rack 17 moves, the movable rod 18 moves along with it, causing the slider 20 to move on the outside of the limiting shaft 19 inside the table groove 12. The spring 21 is sleeved on the outside of the limiting shaft 19 to help the slider 20 return to its original position after moving, ensuring the stable operation of the protective mechanism.

[0047] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
