[0001] This invention relates to the field of laser welding technology, specifically to a laser welding machine with a weld joint protection function. Background Technology

[0002] Laser welding is a technology that uses a laser beam as an energy source to impact the joint of workpieces to achieve welding. As a novel welding method, laser welding is mainly used for welding thin-walled and precision parts, and it has advantages such as high welding speed, high weld quality, and high positioning accuracy.

[0003] Existing laser welding machines conduct the high temperature emitted by the laser welding head onto the material to be welded during welding operations. This causes thin metal plates to soften due to the high temperature, and the material remains at a high temperature, making it inconvenient for workers to remove it. In view of this, we propose a laser welding machine with a weld joint protection function. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laser welding machine with weld joint protection function, thus solving the problems mentioned in the background section.

[0010] According to the above technical solution, it also includes a water replenishment device to prevent the cooling effect from decreasing due to the reduction of cooling water in the cooling platform. The water replenishment device is installed at the cooling platform and includes a water tank box, a hose, a load-bearing plate, a fixed spring, an L-shaped push rod, a baffle, a tension spring, a displacement block, a bonding plate, a moving spring, a trapezoidal block, a sleeve, a moving column, a compression spring, and a return spring.

[0012] According to the above technical solution, the outer wall of the displacement block is slidably connected to the inner wall of the cooling platform, and the displacement block is pressed against the inner wall of the cooling platform by the pressure of the load-bearing plate. The outer wall of the bonding plate is fixedly connected to the outer wall of the displacement block.

One end of the reset spring is fixedly connected to the inner wall of the sleeve, and the other end is fixedly connected to the outer wall of the moving column. When the water in the cooling platform is used for a long time, the water inside gradually decreases, resulting in a reduction in the cooling effect. Through the cooperation of the water tank box, hose, load-bearing plate, fixed spring, L-shaped push rod, baffle and tension spring, the baffle is opened when the water in the cooling platform is less than the fixed state.

[0013] This invention provides a laser welding machine with weld joint protection function. It has the following beneficial effects: 1. This invention incorporates a lifting device. After the welding process is complete, cylinder two moves the clamping plate to both sides. Through the coordinated action of the linkage rod, extrusion plate, moving block, extrusion spring one, and cooling platform, the welded material is kept at a fixed height from the machine body, preventing the welded object from adhering to the machine body surface. This solves the problem of material adhering to the machine body surface after welding, making it inconvenient for workers to remove. Simultaneously, frequent welding operations gradually raise the temperature inside the cooling platform. Through the coordinated action of the cooling platform, support box, airbag, L-shaped limit rod, extrusion spring two, rotating column, knob, storage box, spring, and fan, the water temperature in the upper layer of the cooling platform is raised, causing internal water circulation. This solves the problem of the water temperature in the upper layer of the cooling platform gradually increasing, making it difficult to cool the material.

[0014] 2. This invention incorporates a pressing device. When the cooling platform is in the raised state, the material does not adhere to the surface of the machine body. Through the coordinated action of the moving block, L-shaped connecting rod, support block, extrusion block, support plate, pillar, pressure plate, and torsion spring, the material is prevented from being properly fixed at the weld point during lifting, thus solving the problem of the material tilting to both sides when the weld point of two sets of materials is not fully solidified. Simultaneously, the pressure plate contacts the material. Through the coordinated action of the pressure plate, soft block, and limiting spring, the pressure plate does not directly contact the material head-on. Instead, the soft block makes soft contact with the material first, solving the problem of the pressure plate causing surface deformation of the material when in contact with it.

[0015] 3. This invention incorporates a water replenishment device. When the water level in the cooling platform decreases over time, reducing its cooling effect, the device works in conjunction with a water tank, hose, load-bearing plate, fixed spring, L-shaped push rod, baffle, and tension spring. When the water level in the cooling platform falls below a certain threshold, the baffle opens, allowing water from the water tank to flow back to the cooling platform, replenishing its water supply. This solves the problem of insufficient water level in the cooling platform for effective material cooling. Simultaneously, as the water level decreases, the load-bearing plate rises, opening the baffle. The load-bearing plate, fixed spring, displacement block, bonding plate, moving spring, trapezoidal block, sleeve, moving column, compression spring, and reset spring work together to lock the baffle in place during water replenishment. This prevents the baffle from immediately closing when the water level rises, ensuring the cooling platform is fully replenished. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-11 One embodiment of the present invention is: a laser welding machine with welding position butt protection function, including a machine body 1, a gantry frame 2 fixedly connected to the side wall of the machine body 1, a cylinder 3 fixedly connected to the top of the gantry frame 2, a laser welding head 4 fixedly connected to the output end of the cylinder 3, a controller 5 fixedly connected to the side wall of the gantry frame 2, a cylinder 6 fixedly connected to the top of the machine body 1, a clamping plate 7 fixedly connected to the output end of the cylinder 6, and a clamping plate 7 slidably connected to the top of the machine body 1; and a lifting device is provided inside the machine body 1 to prevent materials from being inconvenient to remove. The lifting device includes a linkage rod 81, a pressing plate 82, a moving block 83, a first pressing spring 84, a cooling platform 85, a support box 86, an airbag 87, an L-shaped limiting rod 88, a second pressing spring 89, a rotating column 810, a knob 811, a storage box 812, a spring 813, and a fan 814. The side wall of the linkage rod 81 is fixedly connected to the side wall of the clamping plate 7, and the linkage rod 81 passes through the machine body 1, with a sliding connection at the penetration point. The bottom of the pressing plate 82 is slidably connected inside the machine body 1. Furthermore, the outer wall of the extrusion plate 82 is fixedly connected to the outer wall of the linkage rod 81, the bottom of the moving block 83 is attached to the inside of the machine body 1, and the side wall of the moving block 83 is slidably connected to the inner wall of the machine body 1. At the same time, the inclined surface of the moving block 83 contacts the side wall of the extrusion plate 82. One end of the extrusion spring 84 is fixedly connected to the top of the moving block 83, and the other end is fixedly connected to the inner wall of the machine body 1. The bottom of the cooling platform 85 is fixedly connected to the top of the moving block 83, and the bottom of the support box 86 is fixedly connected to the cooling platform 85. The inner wall of the cooling platform 85 and the outer wall of the airbag 87 are fixedly connected to the inner wall of the cooling platform 85, and the airbag 87 is limited by the inner wall of the cooling platform 85. The outer wall of the L-shaped limiting rod 88 is fixedly connected to the outer wall of the airbag 87, and the L-shaped limiting rod 88 passes through the cooling platform 85 and the support box 86, with a sliding connection at the passage. One end of the compression spring 89 is fixedly connected to the inner wall of the cooling platform 85, and the other end is fixedly connected to the outer wall of the L-shaped limiting rod 88. The bottom of the storage box 812 is fixedly connected to the inner wall of the cooling platform 85. The inner wall of the warming platform 85 has a rotating column 810 that passes through the body 1, the cooling platform 85 and the support box 86, and is rotatably connected at the point of penetration. The rotating column 810 is limited by an L-shaped limiting rod 88. The top of the knob 811 is fixedly connected to the bottom of the rotating column 810. The outer wall of the fan 814 is fixedly connected to the outer wall of the rotating column 810, thereby limiting the support box 86. One end of the spring 813 is fixedly connected to the inner wall of the storage box 812, and the other end is fixedly connected to the outer wall of the rotating column 810.

[0020] After the material is welded, cylinder 6 drives clamping plate 7 to move to both sides. Through the cooperation of linkage rod 81, extrusion plate 82, moving block 83, extrusion spring 84 and cooling platform 85, the welded material is kept at a fixed height with the machine body 1, preventing the welded object from sticking to the surface of the machine body 1. This solves the problem that the material sticks to the surface of the machine body 1 after welding, making it inconvenient for workers to remove it. Meanwhile, frequent welding work gradually raises the temperature inside the cooling platform 85. Through the coordinated operation of the cooling platform 85, support box 86, airbag 87, L-shaped limit rod 88, compression spring 89, rotating column 810, knob 811, storage box 812, spring 813, and fan 814, the water temperature in the upper layer of the cooling platform 85 is raised, and internal water circulation is carried out. This solves the problem that the water temperature in the upper layer of the cooling platform 85 gradually increases, making it difficult to cool the material.

[0021] In this embodiment, during operation: when the material is placed on the machine body 1 and the laser welding is completed, cylinder 6 drives the clamping plate 7 to reset to one side of the machine body 1. This causes the clamping plate 7 to move from the center position to both sides along with the linkage rod 81, and also causes the extrusion plate 82 to reset to both sides. This causes the extrusion plate 82 to press against the inclined surface of the moving block 83, causing the moving block 83 to move upward, thereby causing the cooling platform 85 to move upward, so that the cooling platform 85 is not in contact with the surface of the machine body 1. At the same time, when the material raises the temperature of the water inside the cooling platform 85, the material inside the cooling platform 85... As the airbag 87 heats up, it gradually expands, causing the L-shaped limiting rod 88 to move towards the outer wall of the cooling platform 85 along with the expansion of the airbag 87. This causes the L-shaped limiting rod 88, which is currently in a limiting state, to gradually move away from the rotating column 810, thereby releasing the restriction on the rotating column 810. This allows the compressed spring 813 to rotate clockwise towards the rotating column 810, causing the spring 813 to drive the rotating column 810 to rotate clockwise, and simultaneously driving the fan 814 to rotate clockwise, causing the still water to circulate internally. When cylinder 6 drives the clamping plate 7 towards the machine body... When the center position of 1 approaches, it drives the linkage rod 81 to move towards the center position, thereby driving the extrusion plate 82 to move towards the center position, so that the extrusion plate 82 gradually moves away from the moving block 83. At this time, the compression spring 84, which is in a compressed state, pushes the moving block 83 downward to fit against the inner wall of the machine body 1 for reset, so that the cooling platform 85 fits against the surface of the machine body 1. When the water temperature in the cooling platform 85 tends to be fixed, the air bag 87 begins to contract, so that the compression spring 89, which is in a compressed state at this time, drives the L-shaped limit rod 88 to move towards the inner wall of the cooling platform 85. As the L-shaped limiting rod 88 gradually approaches the rotating column 810, when the slot on the rotating column 810 no longer contacts the L-shaped limiting rod 88, the rotating column 810 stops the L-shaped limiting rod 88 from moving towards the center position. At this time, manually rotate the knob 811 to drive the rotating column 810 to rotate counterclockwise, thereby driving the spring 813 away from the rotating column 810 and towards the storage box 812. At the same time, when the rotating column 810 rotates to the slot that is in contact with the L-shaped limiting rod 88, the L-shaped limiting rod 88 limits the rotating column 810, preventing the rotating column 810 from rotating continuously.

[0022] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, a pressing device is provided at the lifting device to prevent the material from tilting to both sides. The pressing device includes an L-shaped connecting rod 91, a support block 92, an extrusion block 93, a support plate 94, a pillar 95, a pressure plate 96, a torsion spring 97, a soft block 98, and a limiting spring 99. The outer wall of the L-shaped connecting rod 91 is fixedly connected to the side wall of the moving block 83, and the L-shaped connecting rod 91 penetrates the machine body 1, with a sliding connection at the penetration point. The bottom of the support block 92 is fixedly connected to the top of the L-shaped connecting rod 91, and the bottom of the extrusion block 93 is fixedly connected to the support block 94. The top of block 92 and the top of support plate 94 are fixedly connected to the bottom of gantry 2. The two ends of column 95 are rotatably connected to the outer walls of the two sets of support plates 94. The inner wall of pressure plate 96 is fixedly connected to the outer wall of column 95, and the top of extrusion block 93 is attached to the bottom of pressure plate 96. One end of torsion spring 97 is fixedly connected to the outer wall of support plate 94, and the other end is fixedly connected to the outer wall of pressure plate 96. The outer wall of soft block 98 is slidably connected to the inner wall of pressure plate 96. One end of limit spring 99 is fixedly connected to the top of soft block 98, and the other end is fixedly connected to the inner wall of pressure plate 96.

[0023] When the cooling platform 85 is in the raised state, the material does not adhere to the surface of the machine body 1. Through the cooperation of the moving block 83, L-shaped connecting rod 91, support block 92, extrusion block 93, support plate 94, pillar 95, pressure plate 96 and torsion spring 97, the material is lifted after welding, which prevents the weld from being not completely fixed. This solves the problem that the weld of the two sets of materials is not completely solidified and the material tilts to both sides when lifted. At the same time, the pressure plate 96 comes into contact with the material. Through the cooperation of the pressure plate 96, the soft block 98 and the limiting spring 99, the pressure plate 96 will not make direct face contact with the material when it comes into contact with the material. The soft block 98 will make soft contact with the material first, which solves the problem that the pressure plate 96 causes the surface of the material to deform when it comes into contact with the material.

[0024] It also includes a water replenishment device to prevent the cooling effect from decreasing due to a reduction in cooling water in the cooling platform 85. The water replenishment device is installed at the cooling platform 85 and includes a water tank box 101, a hose 103, a load-bearing plate 104, a fixing spring 105, an L-shaped push rod 106, a baffle 107, a tension spring 108, a displacement block 109, a bonding plate 1010, a moving spring 1011, a trapezoidal block 1012, a sleeve 1013, a moving column 1014, a compression spring 1015, and a return spring 1016. The bottom of the water tank box 101 is fixedly connected to the top of the machine body 1, and one end of the hose 103... One end of the flexible hose 103 is fixedly connected to the bottom of the water tank box 101, and the other end is fixedly connected to the inner wall of the cooling platform 85, and the flexible hose 103 passes through the cooling platform 85. The outer wall of the load-bearing plate 104 is slidably connected to the inner wall of the cooling platform 85. One end of the fixing spring 105 is fixedly connected to the inner wall of the cooling platform 85, and the other end is fixedly connected to the bottom of the load-bearing plate 104. The bottom of the L-shaped push rod 106 is fixedly connected to the top of the load-bearing plate 104. The outer wall of the baffle 107 is slidably connected to the inner wall of the cooling platform 85, and the outer wall of the L-shaped push rod 106 is attached to the baffle. The bottom of the slot at 107 is fixed, and the L-shaped push rod 106 is limited by the inner wall of the cooling table 85. One end of the tension spring 108 is fixedly connected to the top of the baffle 107, and the other end is fixedly connected to the inner wall of the cooling table 85. The outer wall of the displacement block 109 is slidably connected to the inner wall of the cooling table 85, and the displacement block 109 is pressed against the inner wall of the cooling table 85 by the pressure of the load-bearing plate 104. The outer wall of the bonding plate 1010 is fixedly connected to the outer wall of the displacement block 109. One end of the moving spring 1011 is fixedly connected to the outer wall of the bonding plate 1010, and the other end is fixedly connected to the cooling table. The inner wall of the cooling platform 85 and the outer wall of the trapezoidal block 1012 are slidably connected to the inner wall of the cooling platform 85. The outer wall of the sleeve 1013 is fixedly connected to the outer wall of the trapezoidal block 1012, and the length of the sleeve 1013 is the same as the length of the opening of the cooling platform 85. The outer wall of the moving column 1014 is slidably connected to the inner wall of the sleeve 1013. One end of the compression spring 1015 is fixedly connected to the outer wall of the trapezoidal block 1012, and the other end is fixedly connected to the inner wall of the cooling platform 85. One end of the reset spring 1016 is fixedly connected to the inner wall of the sleeve 1013, and the other end is fixedly connected to the outer wall of the moving column 1014.

[0025] When the water in the cooling platform 85 is used for a long time, the water content gradually decreases, resulting in a reduction in cooling effect. By using the water tank box 101, hose 103, load-bearing plate 104, fixing spring 105, L-shaped push rod 106, baffle 107 and tension spring 108 in coordination, when the water in the cooling platform 85 is lower than the fixed state, the baffle 107 is opened, and the water in the water tank box 101 flows to the cooling platform 85 to replenish the water in the cooling platform 85. This solves the problem that the water storage in the cooling platform 85 is too low to cool the materials. Meanwhile, when the water level decreases, it causes the load-bearing plate 104 to rise, opening the baffle 107. Through the coordinated operation of the load-bearing plate 104, fixed spring 105, displacement block 109, bonding plate 1010, moving spring 1011, trapezoidal block 1012, sleeve 1013, moving column 1014, compression spring 1015, and reset spring 1016, when water replenishment is being carried out, the moving column 1014 locks the baffle 107, solving the problem that when the water level in the cooling platform 85 rises, the baffle 107 immediately closes, preventing the cooling platform 85 from being fully replenished.

[0026] In this embodiment, when the cooling platform 85 is in the raised state, the extrusion plate 82 presses against the moving block 83, causing the moving block 83 to move upward, which in turn moves the L-shaped connecting rod 91 upward, thereby causing the support block 92 to move upward, and causing the extrusion block 93 to press against the pressure plate 96 upward, causing the pressure plate 96 to rotate on the support column 95 under force, so that one end of the pressure plate 96 contacts the middle of the material. At the same time, the soft block 98 inside the pressure plate 96 first contacts the material, and while the extrusion block 93 is still moving upward, the soft block 98 gradually moves into the pressure plate 96. Movement; When the extrusion plate 82 gradually moves away from the moving block 83, so that the cooling table 85 is in contact with the surface of the machine body 1, the L-shaped connecting rod 91 moves downward to reset, driving the support block 92 and the extrusion block 93 to move downward together, so that the extrusion block 93 does not apply an upward force to the pressure plate 96, so that the torsion spring 97, which is in a compressed state at this time, generates a force to drive the pressure plate 96 to rotate and reset, so that the soft block 98 in contact with the material gradually moves away from the material. At this time, the limit spring 99, which is in a compressed state, generates an elastic force to drive the soft block 98 away from the inner wall of the pressure plate 96.

[0027] As the water level in the cooling platform 85 gradually decreases, the compressed fixed spring 105 generates elastic force, causing the load-bearing plate 104 to gradually move upward. When the load-bearing plate 104 drives the L-shaped push rod 106 upward, the L-shaped push rod 106 drives the baffle 107 upward to open. At this time, the water in the water tank 101 replenishes the cooling platform 85. Simultaneously, the load-bearing plate 104 presses against the displacement block 109, causing the displacement block 109 to move towards the outer wall of the cooling platform 85. The movement causes the bonding plate 1010 to move together, pressing the inclined surface of the trapezoidal block 1012, causing the trapezoidal block 1012 to move towards the center position. This, in turn, causes the sleeve 1013 to move towards the center position, and the moving column 1014 to move together. When the moving column 1014 first contacts the baffle 107, the trapezoidal block 1012 continues to move in one direction, causing the moving column 1014 to gradually move into the sleeve 1013. When the moving column 1014 contacts the baffle 107, the trapezoidal block 1012 continues to move towards one direction, causing the moving column 1014 to gradually move into the sleeve 1013. When the slots of 7 are in contact and fit together, the return spring 1016 in a compressed state drives the moving column 1014 to move towards the slot. When the water in the cooling platform 85 is replenished, the load-bearing plate 104 is forced to move downward, driving the L-shaped push rod 106 to move downward and reset. At the same time, the load-bearing plate 104 gradually moves away from the displacement block 109, causing the moving spring 1011 in a compressed state to generate elastic force to drive the bonding plate 1010 to move towards the inner wall of the cooling platform 85, driving the displacement block 109 to reset towards the inner wall of the cooling platform 85. This causes the bonding plate 1010 to gradually move away from the trapezoidal block 1012, causing the compression spring 1015 in a compressed state to generate elastic force to drive the trapezoidal block 1012 to move to both sides, driving the sleeve 1013 and the moving column 1014 to reset to both sides, thereby releasing the restriction of the moving column 1014 on the baffle 107, causing the tension spring 108 in a compressed state to generate elastic force to drive the baffle 107 to move downward and reset.
