[0029] This application proposes a laser welding fixture, referring to... Figures 1 to 4The laser welding fixture includes: a support base; a first adsorption component 11 disposed on the support base 10 for adsorbing and mounting the support base 10; two second adsorption components 12 disposed on the upper side of the support base 10, the two second adsorption components 12 being spaced apart, the gap between them being a clearance groove 13; and a limiting member 20 detachably disposed on the upper side of the second adsorption components 12, one side edge of the limiting member 20 being disposed on the upper side of the clearance groove 13 and along the clearance groove 13 for abutting against the edge of the workpiece to be processed, so that the edge of the workpiece to be processed corresponds to the clearance groove 13.

[0030] In this embodiment, the support base 10 can be adsorbed and installed in a suitable position by the first adsorption component 11, ensuring the stable support of the entire fixture. The limiting member 20 is detachably installed on the upper side of the second adsorption component 12, with one edge of its position located on the upper side of the clearance groove 13 and set along the side wall of the clearance groove 13 so as to tightly abut against the edge of the workpiece to be processed. In this way, the position of the workpiece to be processed can be precisely defined so that it corresponds to the clearance groove 13. The second adsorption component 12 can adsorb and fix the workpiece, and then the limiting member 20 can be removed, and another workpiece can be placed on another second adsorption component 12 and matched with the edge of the previous workpiece to be processed. At the same time, another second adsorption component 12 adsorbs and fixes the next workpiece. The adsorption and fixing method of the first adsorption component 11 can arbitrarily adjust the position of the fixture, improving the versatility of the fixture. The setting of the limiting member 20 facilitates the rapid positioning of two workpieces, and the operation is also very simple and convenient.

[0031] In this embodiment, the first adsorption component 11 can employ negative pressure adsorption. It includes an adsorption plate with adsorption holes on its upper surface, and the adsorption plate is connected to an external negative pressure generator via a pipe. The adsorption plate can be installed at a suitable location, such as the bottom or side of the support base 10. When the support base 10 needs to be adsorbed and installed, the air pump is activated. The air pump extracts air from the adsorption plate through the connecting pipe, creating a negative pressure area inside the adsorption plate. The external atmospheric pressure is greater than the internal air pressure of the adsorption plate, thereby generating suction to adsorb and fix the support base 10 onto the target mounting surface, such as a workbench, processing platform, or other equipment surface.

[0032] Negative pressure adsorption generates strong suction, firmly adhering the support base 10 to the mounting surface. Even when the equipment is subjected to vibration or external force during laser welding, the support base 10 remains stable, providing a stable support foundation for the entire laser welding fixture, thereby ensuring the precision and quality of the welding process. Negative pressure adsorption is adaptable to the material and shape of the mounting surface. As long as the mounting surface is relatively flat, good adsorption can be achieved on surfaces such as metal, wood, plastic, or other materials. This allows the laser welding fixture to be used in a variety of different working environments, broadening its application scenarios.

[0033] The negative pressure adsorption process is relatively simple. Adsorption is achieved by simply starting the air pump, and adsorption is released by stopping the pump and opening the exhaust valve. It is convenient, quick, and easy for operators to learn, effectively improving equipment efficiency and convenience. No chemicals or pollutants are generated during the adsorption process, causing no pollution to the environment or workpieces, meeting environmental protection and clean production requirements. It is particularly suitable for laser welding applications with high environmental requirements.

[0034] In addition, the first adsorption component 11 can also adopt electromagnetic adsorption, mainly including an electromagnet. The electromagnet can be embedded in the bottom of the support base 10 or fixedly connected to the support base 10. When adsorption is required, the electromagnet is energized through the power control module, and the electromagnet generates a magnetic field, which is adsorbed on the ferromagnetic mounting base, such as a steel workbench or equipment platform, to achieve fixed installation of the support base 10. After the welding process is completed, the power supply of the electromagnet is cut off, the magnetic field disappears, and the support base 10 is separated from the mounting base.

[0035] Electromagnetic adsorption adjusts the adsorption force by controlling the current and magnetic field strength of the electromagnet. The adsorption force can be flexibly adjusted according to different workpiece weights and processing requirements, ensuring that the support 10 is firmly adsorbed onto the mounting base while avoiding unnecessary damage to the mounting base due to excessive adsorption force. The on / off process of electromagnetic adsorption is rapid, achieving adsorption and release in a short time, greatly improving the installation and disassembly efficiency of laser welding fixtures, shortening auxiliary operation time, and thus improving overall production efficiency. It is particularly suitable for laser welding production lines that require frequent changes in processing positions or rapid tooling switching.

[0036] The electromagnet can be designed to be compact, and its embedded installation within the support base 10 will not significantly increase the size and weight of the equipment. This makes the overall structure of the laser welding fixture more compact and aesthetically pleasing, facilitating installation and use in limited spaces and improving the space utilization rate of the equipment. It automatically releases upon power failure, ensuring timely and reliable separation of the support base 10 from the mounting base after welding or in case of equipment malfunction. This facilitates equipment maintenance and adjustment, while also reducing the risk of component fatigue damage due to long-term adsorption force, thus improving the safety and reliability of the equipment. Of course, the second adsorption component 12 can also use electromagnetic adsorption or negative pressure adsorption to fix the workpiece; specific solutions can be found in the first adsorption component 11 described above, and will not be elaborated here.

[0037] In the above embodiments, the arrangement of the first adsorption component 11 and two second adsorption components 12 enables stable adsorption of the fixture and workpiece, ensuring stability during laser processing, effectively avoiding processing errors caused by workpiece movement, and improving processing accuracy and quality. The design of the limiting component 20, in conjunction with the clearance groove 13, precisely limits the edge of the workpiece to be processed, further enhancing the workpiece's positioning accuracy and making the laser-processed area more precise, meeting the requirements of high-precision processing. This is particularly advantageous for workpieces with complex shapes or high dimensional accuracy requirements. The detachable connection of each component facilitates rapid adjustment and replacement according to different workpieces and processing needs, improving the fixture's versatility and flexibility, reducing production and time costs, and adapting to various laser processing tasks. The overall structure is rationally designed and compactly laid out, easily integrated and coordinated with other laser processing equipment, improving production efficiency and meeting the demands of modern industrial automation and high-efficiency production.

[0038] In some embodiments, the limiting member 20 is provided with a plurality of positioning pins 21, and the second adsorption assembly 12 is provided with mounting holes corresponding to the positioning pins 21, which are respectively located on both sides of the clearance groove 13. The limiting member 20 is provided with a plurality of positioning pins 21, which are typically evenly distributed at a certain interval and arrangement on the edge or specific position of the limiting member 20. The second adsorption assembly 12 is provided with corresponding mounting holes, the positions of which match the positioning pins 21, and the mounting holes are respectively distributed on both sides of the clearance groove 13. When it is necessary to install the limiting member 20 onto the second adsorption assembly 12, the positioning pins 21 are aligned with the mounting holes and inserted, so that the limiting member 20 is fixed onto the second adsorption assembly 12. The distribution design of the mounting holes on both sides of the clearance groove 13 ensures that the limiting member 20 is installed symmetrically and stably on both sides of the clearance groove 13, thereby better limiting and positioning the edge of the workpiece to be processed. The cooperation between the positioning pins 21 and the mounting holes ensures that the installation position of the limiting member 20 on the second adsorption assembly 12 is accurate. This precise positioning method can accurately align the edge of the workpiece to be processed with the clearance groove 13, reducing the workpiece processing error caused by the installation position deviation of the limiting part 20, thereby improving the processing accuracy and quality of the workpiece and meeting the requirements of high-precision laser processing.

[0039] The combination of multiple locating pins 21 and mounting holes not only serves a positioning function but also provides multiple fixing points, making the connection between the limiting component 20 and the second adsorption assembly 12 more secure. During laser processing, the workpiece may be affected by external forces such as laser impact and changes in adsorption force. A stable fixing method can prevent the limiting component 20 from shifting or shaking, ensuring that the workpiece maintains a stable position throughout the processing, thus improving the reliability and safety of the processing. The design of the locating pins 21 and mounting holes makes the disassembly and replacement of the limiting component 20 simple and quick. When it is necessary to adjust or replace the limiting component 20 to accommodate workpieces of different sizes or shapes, simply pull the locating pins 21 out of the mounting holes to quickly remove the limiting component 20, and then install a new limiting component 20. This convenient disassembly and assembly method can reduce equipment adjustment time and improve production efficiency, especially suitable for multi-variety, small-batch laser processing production modes. By quickly and accurately installing the limiting component 20, the clamping and adjustment time of the workpiece can be shortened, allowing the laser processing equipment to enter the processing state more quickly. Meanwhile, stable limiting and fixing methods reduce the failure and defect rate during processing, improve production efficiency, and reduce production costs.

[0040] In some embodiments, an adjusting member 22 may be provided at the edge corresponding to the limiting member 20 and the relief groove 13. The adjusting member 22 is provided with a strip hole, and can be fixed to the limiting member 20 by a screw passing through the strip hole. The adjusting member 22 can be used to abut against the workpiece, specifically for fine-tuning the position of the workpiece.

[0041] In some embodiments, the laser welding fixture further includes an air blowing pipe 30 disposed in the clearance groove 13, the pipe wall of which is provided with multiple air holes. The air blowing pipe 30 is installed in the clearance groove 13, and multiple air holes are evenly distributed on its pipe wall. The aperture and spacing of these air holes are rationally designed to ensure that gas is ejected from the air holes at a suitable flow rate and velocity, covering the processing area within the clearance groove 13. During the laser welding process, gas is continuously blown towards the welding area through the air blowing pipe 30 and the air holes, forming an effective gas protective environment. The air pipe 30 can accurately deliver protective gas (such as argon, helium, etc.) to the welding area, effectively isolating reactive gases such as oxygen and nitrogen in the air, preventing the weld metal from being oxidized and nitrided at high temperatures, thereby improving welding quality and reducing weld defects such as porosity and inclusions. The gas blowing can also remove some of the heat generated during the welding process, playing a certain cooling role, helping to control the heat input during the welding process, reducing the thermal deformation of the workpiece, and improving welding accuracy. The design with multiple pores allows the protective gas to be evenly distributed around the welding area, forming a comprehensive gas protection barrier, further enhancing the protective effect during the welding process and ensuring the stability of welding quality.

[0042] Furthermore, the upper ends of the two spaced-apart side walls of the second adsorption assembly 12 are provided with extensions 14 facing each other. The two extensions 14 can close the upper side of the avoidance groove 13, and the air pipe 30 can be located directly below the extensions 14 to avoid being irradiated by the laser, thus providing a certain degree of protection. At the same time, it can also prevent welding impurities from falling onto the air pipe 30, causing damage or clogging of the air vents. In some embodiments, one end of the second adsorption assembly 12 is provided with a mounting plate 31 that closes one end of the avoidance groove 13, and the other end of the second adsorption assembly 12 is provided with a protective cover 32 that closes the other end of the avoidance groove.

[0043] In this embodiment, the mounting plate 31 is fixedly connected to one end of the second adsorption component 12, sealing one end of the clearance groove 13. It possesses sufficient strength and rigidity to provide a stable connection and seal for one end of the clearance groove 13. The protective cover 32 is installed at the other end of the second adsorption component 12, sealing the other end of the clearance groove 13. Its shape and size are adapted to the clearance groove 13, allowing it to fit tightly against the end of the clearance groove 13, preventing external debris from entering the clearance groove 13 and affecting the processing. Furthermore, the mounting plate 31 and the protective cover 32 prevent high-temperature molten slag and spatter generated during laser welding from splashing out from both ends of the clearance groove 13, protecting the operator's safety from burns and other injuries, and also contributing to maintaining a clean working environment. By sealing both ends of the clearance groove 13, external dust and debris can be effectively blocked from entering the clearance groove 13, preventing contamination of the workpiece surface and the welding process, thereby improving welding quality and reliability. Mounting plate 31 and protective cover 32 can provide certain protection for components (such as air pipe 30) in the clearance groove 13, preventing them from being damaged by external collisions during processing and extending the service life of the equipment.

[0044] Furthermore, one end of the air blowing pipe 30 is mounted on the mounting plate 31, and the protective cover 32 is used to connect with external dust extraction equipment. One end of the air blowing pipe 30 is fixedly connected to the mounting plate 31 and communicates with the inside of the protective cover 32. The protective cover 32 is provided with an interface, which is connected to the external dust extraction equipment through pipes and other connectors to form a complete gas circulation and dust removal system. During laser welding, the air blowing pipe 30 blows protective gas into the welding area, while the dust extraction equipment extracts gas from the welding area through the protective cover 32, expelling harmful gases and fumes generated during the welding process from the outside of the equipment. By connecting the air blowing pipe 30 to the protective cover 32 and the dust extraction equipment, harmful gases and fumes generated during the welding process can be effectively and promptly discharged, improving the air quality of the working environment, protecting the health of operators, and meeting environmental protection and occupational health and safety requirements. The extraction action of the dust extraction equipment can further enhance the gas flow in the welding area, promote the circulation and renewal of the protective gas, increase the concentration of the protective gas in the welding area, thereby better preventing the weld metal from being oxidized and contaminated, and improving the welding quality. This interconnected design helps maintain the cleanliness of the welding area, reduces the accumulation of fumes and harmful gases inside the equipment, lowers the risk of corrosion and damage to internal components (such as optical and electrical components), and extends the equipment's service life and maintenance cycle.

[0045] In some embodiments, the laser welding fixture further includes a base plate disposed at the bottom of the second adsorption component 12, the base plate being used to seal the lower end of the clearance groove 13. The base plate typically has a certain thickness and strength, capable of withstanding certain pressure and impact forces, ensuring the sealing and stability of the lower end of the clearance groove 13. The base plate prevents external objects from entering from the lower end of the clearance groove 13, avoiding interference with the workpiece and welding process. It also prevents high-temperature slag, liquids, etc., generated during welding from leaking from the lower end, protecting the safety of components below the equipment and the working area. Sealing the lower end of the clearance groove 13 helps to form a relatively enclosed welding space, which facilitates better accumulation and function of the protective gas blown by the air pipe 30 within the welding area, improving the utilization efficiency of the protective gas and enhancing the welding protection effect. The presence of the base plate also provides additional support for the second adsorption component 12, enhancing the structural stability of the entire laser welding fixture and ensuring reliability and accuracy during the welding process. A sink can also be provided on the base plate to receive impurity particles generated during welding.

[0046] In some embodiments, the laser welding fixture also includes lifting rings 15 disposed on the side of the support base 10. The position and number of lifting rings 15 are reasonably set according to the weight and balance requirements of the fixture, making it convenient for the hooks of lifting equipment (such as cranes, overhead cranes, etc.) to hook onto, thereby realizing the lifting and transportation of the fixture. The setting of lifting rings 15 facilitates the lifting and movement of the laser welding fixture, enabling it to be quickly and conveniently transferred between different working positions or equipment, improving the flexibility and efficiency of the equipment, especially in large-scale production lines or situations where frequent changes in processing positions are required, which has significant advantages. Using a lifting method can avoid the safety hazards and equipment damage risks that may be caused by manual handling of the fixture, ensuring the integrity of the equipment and the safety of the operators, while also reducing the labor intensity of the operators. The design of the lifting rings 15 can ensure that the fixture remains stable during the lifting process, reducing the shaking or deformation of the fixture caused by improper lifting, thereby ensuring that the accuracy and performance of the fixture are not affected.

[0047] In some embodiments, the laser welding fixture also includes a machine base for mounting the support base 10. The machine base is the basic support structure of the laser welding fixture, typically possessing a large size and high rigidity, providing a stable mounting platform for the support base 10. The machine base can be designed in different forms according to actual production needs, such as floor-standing or tabletop types. Its surface is generally relatively flat and may be equipped with limiting holes or grooves to define the position of the support base 10. The support base 10 is connected to the machine base via a first adsorption component 11, ensuring the stability of the entire fixture during laser welding. The machine base significantly enhances the overall stability of the laser welding fixture, allowing the support base 10 to remain fixed on the machine base, avoiding welding errors caused by the wobbling or displacement of the support base 10, and contributing to improved welding quality and precision. The machine base typically has a suitable working height and operating space, facilitating the installation, debugging, and post-weld cleaning of workpieces by operators, improving work efficiency and ease of operation.

[0048] In some embodiments, a third adsorption module is provided on the machine base, which includes an electromagnetic adsorption module. The electromagnetic adsorption module mainly consists of electromagnets, control circuits, etc., and is installed on the machine base. There can be one or more electromagnets, arranged according to the size and weight of the workpiece to be adsorbed. The control circuit is used to control the energization and de-energization of the electromagnets, thereby realizing the adsorption and release of the workpiece. When it is necessary to fix the ferromagnetic support 10, the control circuit energizes the electromagnets to generate a magnetic field to adsorb the support 10 on the machine base; when it is necessary to change the production line or the workpiece to be processed is changed, the third adsorption module can be de-energized to adjust the position of the support 10. The machine base may include a frame and a base plate disposed on the upper end of the frame. The third adsorption module may be disposed on the lower side of the base plate, and the upper side is used to arrange the support 10 and the first adsorption assembly 11.

[0049] This application also proposes a laser welding device, including a laser welding fixture. The laser welding device further includes a laser welding module disposed on one side of the laser welding fixture. The laser welding device is a complete welding system, in which the laser welding fixture is used to fix and position the workpiece, and the laser welding module is responsible for generating the laser and performing the welding operation. The laser welding module typically includes a laser generator, an optical system (such as a focusing lens, a reflecting mirror, etc.), a cooling system, and a control system. It is installed on one side of the laser welding fixture and connected to the fixture through corresponding guide rails, supports, and other structures to ensure that the laser can accurately act on the part of the workpiece to be welded. During operation, the laser welding module focuses the laser beam onto the surface of the workpiece according to a preset welding program and parameters, achieving efficient welding processing. Integrating the laser welding module and the laser welding fixture together forms an automated welding device that can automatically position, fix, and weld the workpiece, reducing manual intervention and improving production efficiency and welding quality stability.

[0050] In this embodiment, the working principle of the laser welding fixture and equipment is as follows: The support base 10 can be adsorbed and installed in a suitable position by the first adsorption component 11 to ensure the stable support of the entire fixture. The limiting member 20 is detachably installed on the upper side of the second adsorption component 12, with one edge of its side located on the upper side of the clearance groove 13 and set along the side wall of the clearance groove 13 so as to tightly abut against the edge of the workpiece to be processed. In this way, the position of the workpiece to be processed can be precisely defined so that it corresponds to the clearance groove 13. The second adsorption component 12 can adsorb and fix the workpiece. Then the limiting member 20 can be removed, and another workpiece can be placed on another second adsorption component 12 and spliced ​​with the edge of the previous workpiece to be processed. At the same time, another second adsorption component 12 adsorbs and fixes the next workpiece. The adsorption and fixing method of the first adsorption component 11 can arbitrarily adjust the position of the fixture, improving the versatility of the fixture. The setting of the limiting member 20 facilitates the rapid positioning of two workpieces, and the operation is also very simple and convenient.
