[0038] like Figures 1 to 14 As shown, the embodiment of the present application provides a handheld laser welding machine with a guide structure, including a laser welding machine body 10 and a laser welding machine handheld terminal 11 connected to the laser welding machine body 10, and also includes: a workbench 20, an upper buckle plate 30, a displacement guide frame 40, an adaptive track assembly 50, four elastic connection seats 60 and an auxiliary guide sheet 70;

[0039] The workbench 20 is used to place two welded weldments 90; the upper buckling plate 30 can be fixed at different heights above the workbench 20 through the support column 80; the auxiliary guide piece 70 can be detachably placed on the upper buckling plate 30, the lower half of the auxiliary guide piece 70 passes through the workbench 20, and the auxiliary guide piece 70 contacts the welding surfaces of the two weldments 90 to form a welding path of the same shape as the welding surface; the displacement guide frame 40 can be placed on the upper buckling plate 30 to slide linearly along the welding direction, and the laser welding machine handheld end 11 is movably arranged on the displacement guide frame 40; the adaptive track assembly 50 is placed on the upper buckling plate 30 and connected to the auxiliary guide piece 70 and the displacement guide frame 40; the laser welding machine handheld end 11 is moved along the welding path by the adaptive track assembly 50, the buckling plate 30 and the auxiliary guide piece 70; four elastic connecting seats 60 are each two in a group, fixed on the upper buckling plate 30 and the workbench 20 respectively, and elastically connected to the end of the auxiliary guide piece 70.

[0040] The handheld laser welding machine with a guide structure provided by the present application, specifically, the workbench 20 is used to stably place the two weldments 90 to be welded, providing a stable operating surface for the welding operation; the upper buckling plate 30 can be adjusted to a suitable height above the workbench 20 with the help of the supporting components to adapt to the welding height requirements of different weldments 90, so that the welding operation can be carried out in a suitable spatial position; the auxiliary guide piece 70 can be installed on the upper buckling plate 30 and pass through the workbench 20 to contact the welding surface of the weldment 90. Through the setting of the auxiliary guide piece 70, a corresponding welding route can be generated according to the contour of the welding surface of the weldment 90, providing a directional guidance that matches the shape of the welding surface for the subsequent welding action of the handheld end 11 of the laser welding machine; the displacement guide frame 40 is installed on the upper buckling plate 30 and can slide in a straight line along the welding direction. The handheld end 11 of the laser welding machine is placed on the displacement guide frame 40. Therefore, the handheld end 11 of the laser welding machine can Under the constraint of the displacement guide frame 40, it moves along a predetermined straight line trajectory, and simultaneously performs position fine-tuning during this movement process to ensure that the position of the welding point matches; the adaptive track assembly 50 is mounted on the upper buckle plate 30, and by sensing the path information determined by the auxiliary guide piece 70, it forces the laser welding machine handheld end 11 to move along the path for welding, making the welding path more accurate; the four elastic connecting seats 60 are divided into two groups, which are respectively fixed on the upper buckle plate 30 and the workbench 20, and are connected to the ends of the auxiliary guide pieces 70, so that the auxiliary guide pieces 70 before welding are all in a straight line shape, thereby facilitating the contact between the welding surface of the weldment 90 and the auxiliary guide piece 70, and forming an actual welding path; the handheld laser welding machine is able to accurately weld weldments 90 of different shapes, effectively improve the welding accuracy, reduce the welding error rate, improve the welding quality and speed, and reduce the technical difficulty requirements for handheld operation of the laser welding machine.

[0041] Working principle: First, place two weldments 90 on the workbench 20. According to the height requirements of the weldments 90, adjust the height of the upper snap-fit ​​plate 30 above the workbench 20 and fix it. Install the auxiliary guide plate 70 on the upper snap-fit ​​plate 30 and make it pass through the workbench 20 and contact the welding surface of the weldment 90 to form a specific welding path. The displacement guide frame 40 is installed on the upper snap-fit ​​plate 30 and ensures that it can slide linearly along the welding direction. Place the laser welding machine handheld end 11 on the displacement guide frame 40. The adaptive track assembly 50 forces the laser welding machine handheld end 11 to move linearly along the displacement guide frame 40 based on the path information of the auxiliary guide plate 70, ultimately achieving efficient and high-precision welding operations.

[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig.11 As shown, in some examples, further, the displacement guide frame 40 includes: at least two linear sliding support frames 41, a transverse support frame 42, an auxiliary adjustment frame 43 and an adaptive slider 44, at least two linear sliding support frames 41 can be slidably arranged on the top of the upper buckle plate 30; the transverse support frame 42 is connected between the two linear sliding support frames 41 in the horizontal direction, and is movably connected to the laser welding machine handheld terminal 11; the adaptive slider 44 can be movably buckled on the adaptive track assembly 50; the auxiliary adjustment frame 43 is connected to the adaptive slider 44, and the upper part of the auxiliary adjustment frame 43 is fixedly connected to the laser welding machine handheld terminal 11, and the laser welding machine handheld terminal 11 can move laterally on the transverse support frame 42.

[0043] In this example, the linear sliding support frame 41 can slide on the top of the upper buckle plate 30, providing a reliable sliding foundation for the movement process of the laser welding machine handheld terminal 11, ensuring the stability of the laser welding machine handheld terminal 11 during the welding process; the transverse support frame 42 horizontally connects the two linear sliding support frames 41, enhances the structural stability of the displacement guide frame 40, and enables it to maintain its overall shape during the sliding process; the adaptive slider 44 can be movably buckled on the adaptive track assembly 50, and it is forced to move in a further direction according to the shape of the adaptive track assembly 50; the auxiliary adjustment frame 43 connects the adaptive slider 44 and the laser welding machine handheld terminal 11, and transmits the movement of the adaptive slider 44 to the laser welding machine handheld terminal 11, so that the laser welding machine handheld terminal 11 can move synchronously with the adaptive slider 44. During operation, the linear sliding support frame 41 slides to a suitable position on the upper buckle plate 30, and the adaptive track assembly 50 forces the adaptive slider 44 to move, thereby driving the laser welding machine handheld end 11 to produce a moving effect with the same trajectory as the welding path through the auxiliary adjustment frame 43, effectively improving the accuracy of the welding path, reducing the difficulty of welding operation, and the structure is flexible and can adapt to various welding conditions.

[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, in some examples, further, the adaptive track assembly 50 includes: two electromagnet panels 51, an elastic telescopic pipe 52, a deformation track 53, a resistance adjustment part 54 and an external pipe 55, the two electromagnet panels 51 are fixedly arranged on the top of the upper snap-fit ​​plate 30, and correspond to the positions of the two side ends of the upper half of the auxiliary guide plate 70; the elastic telescopic pipe 52 is arranged above the upper snap-fit ​​plate 30 on the outside of the electromagnet panel 51; the deformation track 53 is connected between the two elastic telescopic pipes 52 and is located above the electromagnet panel 51; the external pipe 55 is connected to the outside of the elastic telescopic pipe 52, and the elastic telescopic pipe 52, the deformation track 53 and the external pipe are connected; the resistance adjustment part 54 is fixedly arranged on the external pipe 55.

[0045] In this example, it should be noted that the two electromagnet panels 51 are fixed to the top of the upper buckle plate 30, and their function is to absorb and fix the deformed deformation track 53; when the auxiliary guide piece 70 contacts the welding surface and applies a thrust to the deformation track 53, the deformation track 53 is subjected to the thrust of the auxiliary guide piece 70 and the magnetic attraction, and the shape of the deformation track 53 itself will also match the shape of the welding surface of the weld. At this time, the magnetic force generated by the electromagnet panel 51 absorbs the deformation track 53, so that the deformation track 53 produces a shape change adapted to the welding surface under the action of the auxiliary guide piece 70, and maintains the shape. deformable state; the elastic telescopic pipe 52 is connected to both ends of the deformation track 53, the purpose is to maintain the default shape of the deformation track 53 as a straight line state, and in the process of contacting and deforming with the auxiliary guide piece 70, it gradually changes from the straight line state to the shape of the final welding path, ensuring the consistency between the deformation track 53 and the actual welding path; on the other hand, the elastic telescopic pipe 52 serves as a channel for fluid transmission, is connected to the deformation track 53 and the external pipe 55, to ensure the circulation of the fluid in the entire component, and the setting of the fluid is used as a control medium for controlling the moving speed of the handheld end 11 of the laser welding machine.

[0046] The external pipe 55 is connected to the outside of the elastic telescopic pipe 52 to realize a completely closed fluid circulation channel, so that the fluid can be transmitted between components and is easy to control; the resistance adjustment part 54 is fixed on the external pipe 55, and the flow resistance of the fluid in the system can be changed by adjustment, thereby controlling the moving speed of the adaptive slider 44 and the laser welding machine handheld terminal 11, ensuring that the moving speed of the entire laser welding machine handheld terminal 11 is maintained at a reliable and balanced speed, avoiding the situation of being too fast or too slow during manual handheld movement.

[0047] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, in some examples, further, the elastic connecting seat 60 includes a spring seat 61, and also includes: a telescopic plate 62 and a card slot 63, the telescopic plate 62 is telescopically arranged on the inner side of the spring seat 61; the card slot 63 is vertically penetrated and opened in the outer wall of the telescopic outer end of the telescopic plate 62, and the card slot 63 is detachably connected to the end of the auxiliary guide plate 70.

[0048] In this example, the spring seat 61 serves as the basic component of the elastic connecting seat 60, providing a telescopic space and elastic supporting force for the telescopic plate 62; the telescopic plate 62 can be telescopically placed on the inner side of the spring seat 61, and can flexibly adjust the extension or retraction length according to the force condition of the auxiliary guide piece 70, effectively buffering the auxiliary guide piece 70 approaching a straight line state during the adjustment process before welding, so as to fully and fully accept the force applied by the auxiliary guide piece 70, thereby producing a better adaptable shape with the end face of the weldment 90; the card slot 63 penetrates through the outer wall of the telescopic outer end of the telescopic plate 62 in the vertical direction, and is detachably connected to the end of the auxiliary guide piece 70, facilitating the installation and disassembly of the auxiliary guide piece 70, so that the auxiliary guide piece 70 can be quickly and accurately connected to the elastic connecting seat 60, ensuring that it is in a stable position during work, and at the same time, after assisting in the deformation action of the deformation track 53, the entire auxiliary guide piece 70 can also be disassembled for corresponding welding operations.

[0049] like Figure 2 , Figure 3 , Figure 5 , Fig.12 and Fig.14 As shown, in some examples, further, the auxiliary guide plate 70 includes: a plurality of contact columns 71, a plurality of connecting metal wires 72 and a magnetic sheet 73, the plurality of contact columns 71 are parallel to each other and can move relative to each other; a plurality of connecting metal wires 72 are fixed in sequence and pass through all the contact columns 71, and the plurality of connecting metal wires 72 are arranged in parallel; the magnetic sheet 73 is fixedly arranged at the top of each contact column 71, and can be adsorbed and contacted with the adaptive track assembly 50 to drive the deformation track 53 to form a welding path with the same shape as the end face of the weldment 90.

[0050] In this example, a plurality of contact pins 71 that are parallel to each other and relatively movable can flexibly adjust their positions according to the different shapes of the end faces when in contact with the end faces of the weldment 90, thereby accurately sensing the contour information of the weld surface. A plurality of connecting metal wires 72 that are arranged in parallel and fixed in sequence and penetrate all the contact pins 71 connect the contact pins 71 into a whole, so that the connecting metal wires 72 and the contact pins 71 maintain a certain correlation stability during the relative movement process, thereby preventing the contact pins 71 from becoming scattered or detached. The magnetic sheet 73 fixed on the top of each contact column 71, when approaching the adaptive track assembly 50, is adsorbed and contacted with the deformation track 53 in the adaptive track assembly 50 by means of magnetic force, and the welding surface shape information sensed by the contact column 71 is transmitted to the deformation track 53 through magnetic force, so that the deformation track 53 is deformed under the action of multiple forces such as magnetic force and the thrust of the contact column 71, and finally a welding path with the same shape as the welding surface of the weldment 90 is formed, thereby ensuring that the handheld end 11 of the laser welding machine can weld along a path matching the welding surface of the weldment 90, effectively improving the accuracy of the welding path, reducing welding deviation, enabling the welding machine to adapt to the welding needs of weldments 90 of various shapes, and enhancing the applicability and flexibility of the equipment.

[0051] It should also be noted that several connecting metal wires 72 not only connect the contact pillars 71 into a whole, maintain their association during relative movement, and prevent them from scattering and disengaging, but also because of their certain rigidity, during the operation of the auxiliary guide plate 70, they can effectively constrain the movement range and direction of the contact pillars 71, avoid the complex and unsmooth track shape formed due to the connecting metal wires 72 being too soft, and reduce the difficulty of moving the adaptive slider 44 on the deformation track 53.

[0052] like Figure 1 , Figure 2 and Figure 4 As shown, in some examples, further, the support column 80 includes: at least two guide columns 81 and abutment nuts 82, at least two guide columns 81 are fixedly installed on the top of the workbench 20; the abutment nuts 82 are rotatably and liftably arranged on the outer wall of the guide column 81, and the upper snap-fit ​​plate 30 is sleeved on the outer side of the guide column 81 and is located above all the abutment nuts 82.

[0053] In this example, it can be understood that at least two guide columns 81 are fixed on the top of the workbench 20 to provide vertical positioning guidance for the installation of the upper snap-fit ​​plate 30, so that it can only move up and down along the guide columns 81 to ensure the accuracy of the position; the abutment nut 82 can be rotatably and lifted on the outer wall of the guide column 81, and its height position on the guide column 81 can be changed by rotation, and the upper snap-fit ​​plate 30 is sleeved on the outside of the guide column 81 and is located above all the abutment nuts 82. When the height of the abutment nut 82 is adjusted, the abutment nut 82 can support the upper snap-fit ​​plate 30, thereby fixing the upper snap-fit ​​plate 30 at the required height position, so as to facilitate the flexible adjustment of the height of the upper snap-fit ​​plate 30 according to the actual needs of the weldment 90 and the welding operation, so that the subsequent components connected thereto can be in a suitable spatial position, which is convenient for operation and adjustment and can adapt to different welding scenarios.

[0054] like Fig. 9 As shown, in some examples, further, the adaptive slider 44 includes: two abutment wheels 441, a rotating seat 442 and a top driving magnet 443, the two abutment wheels 441 are rotatably arranged on the outside of the two side walls of the deformation track 53; the rotating seat 442 is connected to the top ends of the two abutment wheels 441 and is located above the deformation track 53; the top driving magnet 443 is fixedly arranged in the rotating seat 442, and the top driving magnet 443 is magnetically transmitted connected to the deformation track 53.

[0055] In this example, the two abutment wheels 441 are rollably arranged on the outer side of the side wall of the deformation track 53. When the displacement guide frame 40 moves, the abutment wheels 441 roll along the lower side wall of the deformation track 53, which can not only support the displacement guide frame 40 and reduce the friction resistance between the displacement guide frame 40 and the deformation track 53, but also constrain the lateral movement of the displacement guide frame 40, so that it can move stably along the new path after the deformation of the deformation track 53; the rotating seat 442 is connected to the top of the two abutment wheels 441 and is located above the deformation track 53, and is a top driving magnet block 44 3 provides an installation foundation and forms a good sleeve shape relative to the outside of the deformation track 53; the top driving magnetic block 443 is fixed in the rotating seat 442 and is connected to the deformation track 53 by magnetic transmission. When the deformation track 53 changes its shape due to the auxiliary guide piece 70, the magnetic force between the top driving magnetic block 443 and the deformation track 53 interacts with each other, thereby limiting the moving speed of the top driving magnetic block 443 and the entire laser welding machine handheld terminal 11 on the deformation track 53 to be constant, effectively ensuring the stability of the welding path and improving the welding quality.

[0056] like Figure 6 , Fig. 9 and Fig.10As shown, in some examples, further, the deformable track 53 component includes: a flexible track 531, a snap-in groove 532, a fluid cavity 533, a plurality of iron blocks 534, a follower movable seat 535 and a follower magnetic block 536, both ends of the flexible track 531 are connected to the elastic telescopic pipe 52, and the flexible track 531 is in a straight line shape in the default state; the snap-in groove 532 is opened in the middle position of the top end of the flexible track 531, and the top driving magnetic block 443 can be movably arranged in the snap-in groove 532; the fluid cavity 533 is opened in the upper half of the inner cavity of the flexible track 531, and is connected with the elastic telescopic pipe 52; a plurality of iron blocks 534 are fixedly arranged in the bottom end face of the flexible track 531 at equidistant intervals, and can be mutually adsorbed with the magnetic sheet 73; the follower movable seat 535 can be movably arranged in the fluid cavity 533; the follower magnetic block 536 is fixedly arranged on the top end face of the follower movable seat 535, and is attracted to the top driving magnetic block 443 in a special shape.

[0057] In this example, both ends of the flexible track 531 are connected to the elastic telescopic pipeline 52. The flexible track 531 is initially in a straight line shape, serving as the basic carrier of the entire welding path and the moving path for guiding welding; the clamping groove 532 is opened in the middle of its top end to provide a movable space for the top driving magnet 443, so that the top driving magnet 443 can be magnetically transmitted with the follower magnet 536 in the flexible track 531 here; the fluid cavity 533 is located in the upper half of the flexible track 531 and is connected to the elastic telescopic pipeline 52, and the internal fluid can flow therein, and the resistance adjustment part 54 changes the fluid The blocking state is used to change the flow speed of the fluid, and the moving resistance of the follower magnet 536 in the fluid chamber 533 is changed accordingly. At the same time, with the help of the magnetic adsorption effect of the follower magnet 536 and the top driving magnet 443, the moving speed of the top driving magnet 443 is limited to the same moving speed of the follower magnet 536. In this way, the moving speed of the displacement guide frame 40 can be limited by the fluid flow during the manual pushing of the staff, so that the moving speed of the whole laser welding machine handheld end 11 on the deformation track 53 is relatively balanced, ensuring the reliability of the welding speed.

[0058] like Figure 7 As shown, in some examples, further, the resistance adjusting portion 54 is provided with: a spinning part 541 and an inner tube 542, the inner tube 542 is provided on the inner side of the resistance adjusting portion 54, and the inner tube 542 is connected to the external pipe 55; the spinning part 541 can be squeezed or moved away from the inner tube 542 and clamped in the resistance adjusting portion 54.

[0059] In this example, it should be noted that when facing weldments 90 of different thicknesses, the welding speed of the laser welding machine is different. Therefore, in this example, the resistance adjusting portion 54 can further change the movement speed limit of the deformation track 53 on the handheld end 11 of the laser welding machine. Specifically, the inner tube 542 is located on the inner side of the resistance adjusting portion 54 and is connected to the external pipe 55. The spinning part 541 is clamped in the resistance adjusting portion 54 and can move in the direction of squeezing or moving away from the inner tube 542. When the spinning part 541 moves toward the direction close to the inner tube 542, it will squeeze the inner tube 542, making the internal space of the inner tube 542 smaller, and the flow rate of the fluid passing through here will be reduced, thereby slowing down the flow speed of the fluid in the entire system, and the corresponding follow-up moving seat 535 will also move in the fluid cavity 533. The speed will also decrease, limiting the moving speed of the adaptive slider 44 and the handheld terminal 11 of the laser welding machine, making them slower; and when the spinning part 541 moves in the direction away from the inner tube 542, the squeezing of the inner tube 542 is reduced, the internal space of the inner tube 542 becomes larger, the fluid flow resistance becomes smaller, and the fluid flow speed is accelerated. Similarly, the movement of the handheld terminal 11 of the laser welding machine becomes easier, and the corresponding moving speed is also improved; by adjusting the fluid speed in this way, the moving speed of the adaptive slider 44 and the handheld terminal 11 of the laser welding machine is controlled to ensure that the moving speed is maintained in a suitable and balanced state, avoiding too fast or too slow speed affecting the welding quality, improving the welding quality and efficiency, and can be flexibly adjusted according to different welding conditions to better adapt to the needs of various welding scenarios.

[0060] In some examples, further, a clamp (not shown in the figure) is provided above the workbench 20 , and the clamp is used to limit the two welds to remain in the center position of the workbench 20 and fix them.

[0061] It can be understood that the clamp is arranged above the workbench 20, and its main function is to limit and fix the position of the two weldments 90, and constrain the weldment 90 in the center position of the workbench 20 through its own structure; before the welding operation, the weldment 90 is placed on the workbench 20, and then the clamp is used to apply force to the weldment 90 from different directions, so that the weldment 90 is firmly fixed in the center position to avoid position displacement or shaking of the weldment 90 during the welding process; in this way, the subsequent auxiliary guide piece 70 can more accurately obtain the accurate shape information of the welding surface when contacting the welding surface of the weldment 90 to shape the welding path, and the displacement guide frame 40 drives the handheld end 11 of the laser welding machine to move along the welding path. There will be no deviation due to the change of the position of the weldment 90, ensuring that the entire welding process is carried out along the preset accurate path, effectively improving the accuracy of the welding path.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
