Description

Technical Field

[0001] This application relates to the technical field of laser welding equipment, and in particular to a dual-material automatic laser welding machine. Background Technology

[0002] In the manufacturing of electronic products, medical devices, and automotive parts, it is often necessary to join two materials. A typical process is to first cut material one (e.g., a continuous strip of welding sheet) to a fixed length, then precisely pre-fix the cut material one to a specific position on material two (e.g., a base strip), and finally achieve a high-strength permanent connection between the two through laser deep penetration welding.

[0003] While automated laser welding equipment exists on the market, most of them are general-purpose devices designed for welding single materials or two pre-assembled parts. These devices lack the front-end processing capabilities to cut material one from a continuous conveyor belt online and pick up, transfer, and precisely pre-press the tiny material one onto material two, thus lacking integrated, high-efficiency equipment. Summary of the Invention

[0004] To meet the need for automated laser welding of two materials, this application provides an automated laser welding machine for two materials.

[0005] This application provides a dual-material automatic laser welding machine, which adopts the following technical solution: A dual-material automatic laser welding machine includes a base, on which a feeding module, a mold module, a welding module and a moving module are provided; The feeding module includes a first feeding structure and a second feeding structure, which are respectively used for feeding different materials. The base is provided with a positioning strip and a positioning platform. The positioning strip has a first placement groove for moving material one and a second placement groove for moving material two on different sides. The positioning strip has a through hole connecting the first placement groove and the second placement groove. The positioning platform has a receiving groove for moving materials. The receiving groove and the second placement groove are connected to each other to receive material two fed in by the second placement groove and material one after cutting. The mold module includes an upper pressing structure, which includes an upper pressing drive and an upper pressing block. The upper pressing drive can drive the upper pressing block through the perforation to cut and separate material one located in the first placement groove and press it onto material two located in the receiving groove. The welding module is used to weld material one onto material two. The moving module is used to drive material one and material two to move along the directions of the feeding module, the mold module and the welding module.

[0006] By adopting the above technical solution, this solution integrates the first feeding structure, the second feeding structure, the mold module, the welding module, and the moving module onto the same base, realizing the automatic feeding of two materials, online fixed-length cutting of material one, automatic pre-pressing of material one and material two, and laser welding—a fully integrated continuous operation. This fundamentally solves the deficiency of existing equipment in lacking the ability to cut, pick up, and precisely pre-press the front end of continuous material strips online. Specifically, the positioning strip has a first placement slot and a second placement slot on both sides, and through perforations allow the upper pressing block to pass through the cut material one and directly press it onto material two in the receiving slot. Cutting and pre-fixing are completed in one step, resulting in an extremely compact structure that significantly shortens the material flow path, ensures the relative positional accuracy of material one and material two during pre-fixing, and significantly improves production efficiency and automation.

[0007] Optionally, the upper pressing drive is provided with an upper pressing plate, and the upper pressing block is slidably connected to the lower part of the upper pressing plate in the vertical direction. The upper pressing plate is provided with an upper pressing elastic element, which drives the upper pressing block to move towards the ground. The upper pressing plate is provided with a limiting rod, and the upper pressing block is provided with a limiting hole for the limiting rod to pass through downward. When the upper pressing drive drives the upper pressing plate to descend, the upper pressing block first cuts material one, pushes material one to abut against material two, and the limiting rod extends out from the limiting hole and inserts into the aligned holes on material one and material two for positioning.

[0008] By adopting the above technical solution, and by setting an upper pressing plate on the upper pressing drive component, and suspending the upper pressing block below the upper pressing plate in an elastic floating manner, a step-by-step continuous action of cutting pre-pressing and precise positioning is achieved. When the upper pressing plate descends, the upper pressing block first contacts and cuts material one, and then elastically pre-presses the cut material one onto material two, completing flexible pre-fixation; as the upper pressing plate continues to descend, the limiting rod fixed on it extends from the limiting hole of the upper pressing block and smoothly inserts into the hole where material one and material two are already aligned. This sequential design of "flexible pressing first, then rigid needle positioning" cleverly integrates the three processes of cutting, pre-pressing, and alignment into a continuous pressing action with a compact action rhythm and extremely high positioning accuracy. The elastic clamping mechanism avoids damage to micro-sized materials from hard impacts, while the "common-hole pin" precise positioning achieved by the limiting rod passing through the holes of the two materials ensures that the relative positions of the two materials are absolutely reliable before welding. This fundamentally eliminates the micro-misalignment that may occur during the pre-pressing process, and provides a guarantee for the alignment accuracy and high consistency of subsequent laser welding.

[0009] Optionally, the mold module further includes a lower pressing structure, which is located directly below the upper pressing structure. The positioning platform has a receiving hole that connects to the receiving groove. The lower pressing structure includes a lower pressing drive and a lower pressing block. The lower pressing block is located on the lower pressing drive, which is mounted on the machine base. The lower pressing drive is used to drive the lower pressing block through the receiving hole to abut against the material.

[0010] By adopting the above technical solution and adding a lower pressing structure located directly below the upper pressing structure, when the lower pressing drive drives the lower pressing block through the receiving hole to abut against material two, it can provide stable back support for material two, so that material one and material two are subjected to uniform force and fit tightly during pressing, avoiding pre-fixation failure due to suspension deformation or displacement of material two, significantly enhancing the reliability of pre-pressing, and providing a guarantee for obtaining high-quality welded joints.

[0011] Optionally, the mold module further includes a fixing structure, which includes a fixing block and a fixing elastic element. The fixing elastic element is disposed on the upper pressing drive, and the fixing block is disposed on the fixing elastic element. When the upper pressing drive drives the upper pressing block to descend, the fixing elastic element first drives the fixing block to press against the material in the first placement groove, so as to achieve fixing before cutting.

[0012] By adopting the above technical solution, a fixed structure consisting of a fixed elastic element and a fixed block is added to the mold module. When the upper pressing drive is activated, the fixed elastic element first drives the fixed block to elastically press against the material in the first placement groove, realizing the sequential action of "fixing first, then cutting". This design can compact the material at the moment of cutting, completely avoiding material movement and positional deviation caused by shearing force, ensuring neat cutting edges and accurate fixed length dimensions.

[0013] Optionally, the positioning strip has an installation groove that connects the first placement groove and the through hole. An installation block is provided in the installation groove for placing material one. The side of the installation block forms a cutting mating surface. When the upper pressing block presses the material, the outer side of the upper pressing block and the cutting mating surface of the installation block together cut the material one.

[0014] By adopting the above technical solution, an installation block is set in the installation groove of the positioning strip, and the side of the installation block forms a cutting mating surface, which together with the outer side of the upper pressing block forms a shearing edge. When the upper pressing block is pressed, the material is cut by shearing, resulting in a flat and burr-free cutting surface. The cutting quality is far superior to ordinary punching. Furthermore, the installation block is detachable and replaceable, making it easy to adapt to different specifications of materials and easy to maintain the cutting edge, thus improving the equipment's adaptability to different materials and ease of maintenance.

[0015] Optionally, the moving module includes a moving drive and a moving disk. The moving disk is disposed on the moving drive, which is disposed on the base. The outer surface of the moving disk is provided with a plurality of protrusions, which are distributed along the circumference of the moving disk. The protrusions are used to insert into the holes corresponding to material one or material two.

[0016] By adopting the above technical solution, the moving module uses a moving disk with multiple circumferentially distributed protrusions. Stepping transmission is achieved by inserting the protrusions into the corresponding holes of material one or material two. This toggle positioning method eliminates the relative slippage between the material and the conveying component, ensuring precise pitch and strict synchronization of material movement. It ensures that the actions of each station are highly coordinated with the cutting, pressing, and welding cycles, improving the reliability of material transmission and the accuracy of positional repeatability.

[0017] Optionally, there are two moving modules, one of which is located between the mold module and the welding module, and the other is located on the side of the mold module away from the welding module. The positioning platform has a through hole for connecting the receiving groove, and the through hole is for the protrusion to be inserted.

[0018] By adopting the above technical solution, two moving modules are respectively arranged on both sides of the mold module. Combined with the through holes on the positioning table for protrusion insertion, a continuous transmission layout is realized, in which materials are fed into the mold station from the front end and stably delivered from the rear end after welding. This allows material two and the combined workpiece to flow smoothly throughout the entire process chain without any interruptions or accumulation. The through holes provide space for protrusion movement, further ensuring the smoothness of the transmission action and the accurate matching of the holes, thus improving the automation level and cycle stability of the entire machine's material flow. The moving module located between the welding module and the mold module can move the pressed material and material two at the same time. By solving the movement problem of material two and the pressed material with one moving module, there is no need to set up a separate transfer mechanism for the pressed material, which greatly simplifies the equipment structure and reduces manufacturing costs. Meanwhile, since the forward movement of material 2 and the transmission of the pressing component are controlled by the same drive source and the same moving disk, the two are naturally synchronized in terms of movement timing and pitch. This fundamentally avoids problems such as material misalignment, pulling and piling caused by asynchronous or cumulative errors in multiple transmission systems, and significantly improves the coordination accuracy of material supply and pre-pressing action and the reliability of overall operation.

[0019] Optionally, the machine base is provided with a positioning module, which is located between the mold module and the welding module. The positioning module includes a positioning seat and a positioning rod. The positioning seat is disposed on the machine base, and the positioning rod is slidably disposed on the positioning seat. The positioning rod is used to insert into the hole corresponding to the material.

[0020] By adopting the above technical solution, a positioning module with a sliding positioning rod is set between the mold module and the welding module. The positioning rod is inserted into the corresponding hole of the material again to perform the final precise positioning of the pre-pressed material component before welding. This effectively eliminates the slight position deviation that may accumulate during the multi-station transmission process, ensures that the laser welding focus is accurately aligned with the predetermined part to be welded, and greatly improves the welding position accuracy and the welding consistency of the final product.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This solution integrates the first feeding structure, the second feeding structure, the mold module, the welding module, and the moving module onto a single base, achieving fully integrated continuous operation of automatic feeding of two materials, online fixed-length cutting of material one, automatic pre-pressing of material one and material two, and laser welding. This fundamentally solves the deficiency of existing equipment in lacking the ability to cut, pick up, and precisely pre-press the continuous material strip online. Specifically, the positioning strip has a first placement slot and a second placement slot on each side, and perforations allow the upper pressing block to pass through the cut material one and directly press it onto material two in the receiving slot. Cutting and pre-fixing are completed in one step, resulting in an extremely compact structure that significantly shortens the material flow path, ensures the relative positional accuracy of material one and material two during pre-fixing, and significantly improves production efficiency and automation.

[0022] Two moving modules are positioned on either side of the mold module. Combined with through holes on the positioning platform for protrusion insertion, this achieves a continuous transport layout where materials are fed into the mold station from the front end and stably discharged from the rear end after welding. This ensures smooth flow of material two and the assembled workpiece throughout the entire process chain without interruption or accumulation. The through holes provide space for protrusion movement, further guaranteeing smooth transport and accurate alignment with the holes, thus improving the automation level and cycle stability of the entire machine's material flow. The moving module located between the welding module and the mold module can move the pressed material and material two simultaneously. By using a single moving module, the movement of both material two and the pressed material can be solved at the same time, eliminating the need for a separate transfer mechanism for the pressed material, greatly simplifying the equipment structure and reducing manufacturing costs. Meanwhile, since the forward movement of material 2 and the transmission of the pressing component are controlled by the same drive source and the same moving disk, the two are naturally synchronized in terms of movement timing and pitch. This fundamentally avoids problems such as material misalignment, pulling and piling caused by asynchronous or cumulative errors in multiple transmission systems, and significantly improves the coordination accuracy of material supply and pre-pressing action and the reliability of overall operation.

[0025] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0026] This embodiment discloses a dual-material automatic laser welding machine. (Refer to...) Figure 1An automatic laser welding machine for two materials includes a base 1, on which are mounted a feeding module 2, a mold module 3, a positioning module 4, a welding module 5, and a moving module 6. The feeding module 2 is used to feed material one and material two. The mold module 3 is used to cut material one and press it onto material two. The positioning module 4 allows the operator to manually and precisely position the materials for subsequent automatic operation. The welding module 5 is used to weld material one and material two. The moving module 6 drives the materials to move along the directions of the feeding module 2, mold module 3, positioning module 4, and welding module 5.

[0027] Reference Figure 1 The feeding module 2 includes a first feeding structure 21 and a second feeding structure 22, both of which are mounted on the base 1. The first feeding structure 21 feeds material one, and the second feeding structure 22 feeds material two. The second feeding structure 22 is located on the side of the first feeding structure 21 closest to the ground.

[0028] Reference Figure 1 and Figure 2 The first feeding structure 21 includes a feeding motor 211 and a feeding turntable 212. The feeding motor 211 is fixedly connected to the base 1, and the feeding turntable 212 is fixedly connected to the drive shaft of the feeding motor 211. When the feeding motor 211 starts, it drives the feeding turntable 212 to rotate, thereby feeding material one. The second feeding structure 22 is the same as the first feeding structure 21, and its function is to feed material two.

[0029] Reference Figure 1 and Figure 3 A positioning platform 11 is fixedly connected to the base 1, and the positioning platform 11 extends along the length of the base 1. A receiving groove 111 is formed on the surface of the positioning platform 11 away from the ground, and the receiving groove 111 extends along the length of the positioning platform 11.

[0030] Reference Figure 3 and Figure 4 A positioning strip 12 is fixedly connected to the base 1. The positioning strip 12 extends along the length of the positioning platform 11 and is located on the side of the positioning platform 11 away from the ground. A first placement groove 121 is formed on the side of the positioning strip 12 away from the ground for material one to move. A second placement groove 122 is formed on the side of the positioning strip 12 closer to the ground for material two to move. The second placement groove 122 and the receiving groove 111 are interconnected, so that material two can move directly from the second placement groove 122 into the receiving groove 111, and the pressed material can continue to move along the receiving groove 111. A through hole 123 is formed on the positioning strip 12 to connect the first placement groove 121 and the second placement groove 122.

[0031] Reference Figure 5 The mold module 3 includes an upper pressing structure 31, a fixing structure 32, and a lower pressing structure 33.

[0032] Reference Figure 6 The upper pressing structure 31 is used to cut material one and press material one onto material two. The fixing structure 32 is used to fix material one so that the upper pressing structure 31 can cut material one. The lower pressing structure 33 is used to abut material two to ensure that material one and material two are firmly pressed together.

[0033] Reference Figure 6 and Figure 7 The upper pressing structure 31 includes an upper pressing drive 311 and an upper pressing block 312. The upper pressing drive 311 is disposed on the base 1, and an upper pressing plate 313 is fixedly connected to the upper pressing drive 311. The upper pressing drive 311 is used to drive the upper pressing plate 313 to move in the vertical direction.

[0034] Reference Figure 6 and Figure 7 Multiple upper pressing elastic elements 314 are fixedly connected to the surface of the upper pressing plate 313 facing the ground. In this application, the upper pressing elastic elements 314 are springs. One end of the spring is fixedly connected to the surface of the upper pressing plate 313 near the ground, and the other end of the spring is fixedly connected to the surface of the upper pressing block 312 away from the ground. The spring drives the upper pressing block 312 to move away from the upper pressing plate 313. The upper pressing block 312 can slide vertically below the upper pressing plate 313. The upper pressing block 312 passes through the through hole 123 to cut the material one and presses the material one into the material two in the receiving groove 111.

[0035] Reference Figure 6 and Figure 7 Multiple limiting rods 315 are fixedly connected to the surface of the upper pressing plate 313 near the ground. The limiting rods 315 can be inserted into the corresponding holes in material one and material two. The surface of the upper pressing block 312 is provided with limiting holes 316 for the limiting rods 315 to pass through downwards. When the upper pressing drive 311 drives the upper pressing plate 313 to fall, the upper pressing block 312 first cuts material one. As the upper pressing block 312 continues to press down, material one abuts against material two. At this time, the limiting rods 315 extend from the limiting holes 316, allowing the limiting rods 315 to be inserted into the corresponding holes on material one and material two for positioning. In this application, the limiting rods 315 can pass through the corresponding holes of the welding sheet and the bottom strip, and flatten the protrusions of the bottom strip to achieve relative fixation of the bottom strip and the welding sheet.

[0036] Reference Figure 6 and Figure 8The positioning strip 12 has a mounting groove 124 on its side, which extends vertically and connects the first placement groove 121 and the second placement groove 122. A mounting block 125 is fixedly connected within the mounting groove 124. The surface of the mounting block 125 away from the ground is coplanar with the bottom wall of the first placement groove 121, allowing material to pass through. The side of the mounting block 125 forms a cutting mating surface, which is abutted by the outer surface of the upper pressing block 312, enabling the upper pressing block 312 and the mounting block 125 to jointly cut the material.

[0037] Reference Figure 6 The fixing structure 32 includes a fixing block 321 and a fixing elastic element. A fixing groove is formed on the surface of the upper pressing block 312 near the ground. In this application, the fixing elastic element is a fixing spring. One end of the fixing spring is fixedly connected to the fixing groove, and the other end of the fixing spring is fixedly connected to the fixing block 321. The fixing spring drives the fixing block 321 to move in a vertically downward direction, so that the fixing block 321 presses against the material.

[0038] Reference Figure 6 When the fixed spring drives the fixed block 321 to move, the fixed block 321 first presses against the material 1 in the first placement groove 121, so that the material 1 can be fixed in the first placement groove 121. As the upper pressing plate 313 continues to move down, the upper pressing block 312 can cut the material 1 so that the material 1 can be fixed first and then cut.

[0039] Reference Figure 5 and Figure 9 The positioning platform 11 has a receiving hole 112 that connects to the receiving groove 111, and the receiving hole 112 extends vertically. The pressing structure 33 includes a pressing drive 331 and a pressing block 332. The pressing drive is fixedly connected to the base 1, and the pressing block 332 is disposed on the pressing drive 331. The pressing drive 331 drives the pressing block 332 to move vertically, and the pressing block 332 passes through the receiving hole 112 and abuts against the second material, so as to realize the mutual pressing of the second material and the first material.

[0040] Reference Figure 1 There are three moving modules 6. The first moving module 6 is located between the mold module 3 and the welding module 5. The second moving module 6 is located on the side of the mold module 3 away from the welding module 5.

The moving module 6 located on the side of the mold module 3 away from the welding module 5 can move material one. The moving module 6 located between the mold module 3 and the welding module 5 can move material two and the pressed material. The moving module 6 located on the side of the positioning module 4 away from the pressing module is used to realize the material unloading movement.

[0041] Reference Figure 10 The moving module 6 includes a moving drive component 61 and a moving disk 62. The moving drive component 61 is fixedly connected to the base 1. In this application, the moving drive component 61 is a stepper motor. The moving disk 62 is fixedly connected to the drive shaft of the moving drive component 61. The moving drive component 61 can drive the moving disk 62 to rotate a specific angle.

[0042] Reference Figure 10 Multiple protrusions 63 are fixedly connected to the outer surface of the moving disk 62. The multiple protrusions 63 are distributed in a circumferential array along the moving disk 62, and the protrusions 63 can be inserted into the air between the corresponding material one and material two to achieve the precise forward movement of the material to the position of one workstation.

[0043] Reference Figure 3 and Figure 10 The positioning platform 11 has a through hole 113 that connects to the receiving groove 111, through hole 113 for the protrusion 63 to be inserted. The positioning strip 12 has a placement hole 126 that connects to the first placement groove 121, placement hole 126 for the protrusion 63 to be inserted. When the moving disk 62 rotates, the protrusion 63 in the moving disk 62 can be inserted into the hole corresponding to the material to realize the quantitative movement of the material.

[0044] Reference Figure 1 and Figure 10 The positioning module 4 is located between the mold module 3 and the welding module 5. The positioning module 4 includes a positioning seat 41, a positioning spring 42, and a positioning rod 43. The positioning seat 41 is fixedly connected to the side of the positioning platform 11 away from the ground. A sliding hole 44 is provided on the positioning seat 41 for the positioning rod 43 to slide. The positioning spring 42 is sleeved on the positioning rod 43. A positioning block 45 is fixedly connected to the end face of the positioning rod 43. One end of the positioning spring 42 abuts against the surface of the positioning seat 41 away from the positioning platform 11, and the other end abuts against the side of the positioning block 45 near the positioning platform 11. The positioning spring 42 drives the positioning rod 43 to move vertically upwards, and the positioning rod 43 can be inserted into the corresponding hole of the material.

[0045] Reference Figure 10 Before starting the equipment, the operator first presses the positioning rod 43 to insert the positioning rod 43 into the corresponding hole of the material, and then installs the material into the protrusion 63 of the moving plate 62 to achieve the positioning of the material.

[0046] Reference Figure 1 The welding module 5 is used to realize laser welding. The welding module 5 can emit a high-energy laser beam to penetrate or melt the contact surface of material one and material two, causing them to fuse at the molecular level and form a strong weld point.

[0047] The implementation principle of a dual-material automatic laser welding machine according to an embodiment of this application is as follows: Material 1 is moved to the first placement groove 121 of the positioning bar 12 through the first feeding module 2 and the moving module 6, and Material 2 is moved to the receiving groove 111 of the positioning table 11 through the second feeding module 2 and the moving module 6. Then, the upper pressing drive 311 drives the upper pressing plate 313 to move down, so that the fixing block 321 abuts against material one to fix material one. The upper pressing block 312 cuts material one and makes material one abut against material two. Then, the positioning rod 43 passes through the hole of material one or material two. Finally, the lower pressing drive 331 drives the lower pressing block 332 to lift up, so as to achieve the pressing process of material one and material two. Finally, welding module 5 performs laser welding on material one and material two, and the material is unloaded as moving module 6 moves.
