Description

Technical Field

[0001] This utility model relates to the field of laser welding, and in particular to a safe laser welding device. Background Technology

[0002] Laser welding is a welding method that uses a focused laser beam as an energy source to bombard the workpiece with the heat generated. Due to the optical properties of lasers, such as refraction and focusing, laser welding is very suitable for welding tiny parts and components with poor accessibility.

[0003] In traditional technology, laser welding equipment mainly consists of a laser head and a clamping component set on the machine. After the clamping component fixes the welding target, the laser head welds the target. When disassembling and assembling the welding target, there is a risk of accidental triggering of the laser head because the operator is close to the welding area of ​​the laser head, posing a safety hazard of being burned by the laser. In addition, laser welding lacks flexibility, and complex welding operations require multiple disassembly and reassembly for alignment, resulting in low welding processing efficiency.

[0015] In this embodiment, the inner wall of the U-shaped groove is covered with a lubricating layer.

[0016] The embodiments of this utility model have at least the following beneficial effects:

[0017] The rotary drive module rotates the gripper jaws in conjunction with the laser welding head, meeting the requirements for circumferential welds.

[0033] Laser welding is a welding method that uses a focused laser beam to bombard the workpiece with the heat generated. Due to the optical properties of lasers, such as refraction and focusing, laser welding is very suitable for welding tiny parts and components with poor accessibility. In traditional technology, laser welding equipment mainly consists of a laser head and a clamping device mounted on a machine base. After the clamping device fixes the welding target, the laser head welds the target. When disassembling and assembling the welding target, there is a risk of accidental laser head triggering and a safety hazard of laser burns because the operator is close to the welding area of ​​the laser head. Furthermore, laser welding lacks flexibility, and complex welding operations require multiple disassembly and reassembly adjustments, resulting in low welding efficiency.

[0034] To address safety concerns, while a linear positioning structure could improve safety by transferring the clamped component outside the laser head's welding area, it also occupies a large space and severely limits its application. Therefore, there is an urgent need for a compact, safe, and reliable laser welding device capable of rapid switching between workstations and ensuring high-efficiency welding processes.

[0035] The following is for reference only. Figure 1 To be continued Figure 6 This invention describes a safe laser welding device that can be disassembled and welded in sections, offering high safety performance, high switching efficiency, flexible welding processing, and high welding efficiency.

[0036] Reference Figures 1 to 6 A safe laser welding device according to an embodiment of the present invention includes:

[0037] The machine 100 is provided with a disassembly station 110 and a welding station 120. The disassembly station 110 is located outside one side of the welding station 120.

[0038] The clamping assembly 200 includes a positioning base 210, a flipping base 220, a clamping jaw 230, and a rotary drive module 240. The clamping jaw 230 can be configured as a three-jaw chuck and is used to clamp the welding target. The rotary drive module 240 can be configured as a rotary motor and is connected to the flipping base 220. The clamping jaw 230 is connected to the rotary drive module 240 and is used to drive the clamping jaw 230 to rotate. The flipping base 220 is provided with a flipping shaft 221 and a sliding shaft 222 that are parallel to each other. Preferably, the flipping shaft 221 and the sliding shaft 222 are distributed along the extension direction of the rotation axis of the clamping jaw 230, and the flipping shaft 221 is located on the side of the flipping base 220 away from the disassembly / assembly station 110. The positioning base 210... The device includes an L-shaped flip groove 211 and a quarter-circle arc-shaped slide groove 212. The slide groove 212 is arc-shaped with a central angle of 90 degrees. The turning point of the flip groove 211 is located at the center of the slide groove 212. The flip groove 211 is located on the side of the slide groove 212 closest to the disassembly / assembly station 110. A flip shaft 221 is slidably connected to the flip groove 211, and a sliding shaft 222 is slidably connected to the slide groove 212. The opposite ends of the slide groove 212 are respectively connected to a first positioning groove 213 and a second positioning groove 214, both extending towards the flip groove 211. That is, the opposite ends of the slide groove 212 are respectively connected to the first positioning groove 213 and the second positioning groove 214, and both the first positioning groove 213 and the second positioning groove 214 face the center of the slide groove 212. The two branches of the extension and flipping groove 211 are respectively matched with the first positioning groove 213 and the second positioning groove 214. That is, the extension direction and extension length of one branch of the flipping groove 211 are the same as the extension direction and extension length of the first positioning groove 213, and the extension direction and extension length of the other branch of the flipping groove 211 are the same as the extension direction and extension length of the second positioning groove 214. The second positioning groove 214 is located on the side of the first positioning groove 213 near the disassembly / assembly station 110, so that the two ends of the movement path of the gripper 230 are respectively located at the welding station 120 and the disassembly / assembly station 110. When the flipping adjustment seat 220 is flipped, the gripper 230 can reach the welding station 120 or the disassembly / assembly station 110. When disassembling and assembling the welding target, the safety of operation can be effectively improved. The slide groove 212 is also connected to a receiving groove 215 facing the first positioning groove 213. The receiving groove 215 contains an elastic element 216 and a locking block 217. The elastic element 216 can be a spring, with a free length less than the length of the receiving groove 215. The elastic element 216 connects the flip seat 220 and the locking block 217, causing the locking block 217 to tend to move closer to the first positioning groove 213. The locking block 217 has a guide surface 218 facing the slide groove 212 and the first positioning groove 213. In the spring's natural state, the guide surface 218 is located in the slide groove 212. The guide surface 218 provides a guiding drive structure for the movement of the sliding shaft 222, thereby improving the smoothness of the action when the locking block 217 and the sliding shaft 222 are linked. Preferably...The end of the locking block 217 near the first positioning groove 213 is spherical, forming a guide surface 218 for effective guidance. The locking block 217 is slidably connected to the storage groove 215 and is also engaged with the positioning seat 210.

[0039] Welding assembly 300 is located at welding station 120. Welding assembly 300 includes a three-axis positioning mechanism 310 and a laser welding head 320. The three-axis positioning mechanism 310 is connected to the machine base 100, and the laser welding head 320 is connected to the three-axis positioning mechanism 310. The three-axis positioning mechanism 310 is used to drive the laser welding head 320 to achieve three-axis movement above the welding station 120. The optical axis of the laser welding head 320 is perpendicular to the rotation axis of the gripper 230. The laser welding head 320 can be a fiber laser or a semiconductor laser.

[0040] It should be noted that the flip groove 211 can be configured to include a flip hole and a first clearance groove and a second clearance groove connected to the flip hole. The extension direction of the first clearance groove is the same as the extension direction of the first positioning groove 213, and the extension direction of the second clearance groove is the same as the extension direction of the second positioning groove 214. This is so that when the sliding shaft 222 enters the first positioning groove 213, the first clearance groove provides sufficient space for the movement of the flip shaft 221, and when the sliding shaft 222 enters the second positioning groove 214, the second clearance groove provides sufficient space for the movement of the flip shaft 221.

[0041] The rotary drive module 240 drives the clamping jaws 230 to rotate and cooperate with the laser welding head 320. The clamping jaws 230 can achieve 360-degree continuous rotation in all directions, which can meet the requirements of circumferential welds. Furthermore, the three-axis positioning mechanism 310 drives the laser welding head 320 to further achieve multi-dimensional precision welding. The welding process has high accuracy, and complex trajectory welding can be achieved in a single clamping. The welding process is flexible and efficient. By physically separating the disassembly station 110 and the welding station 120, the clamping jaws 230 reach the working states of the welding station 120 and the disassembly station 110 respectively. Figure 1 and Figure 2As shown, when operators disassemble or assemble the welding target, they can effectively stay away from the laser welding station 120, fundamentally avoiding safety risks such as laser radiation, molten slag splash, and accidental triggering. This ensures high safety performance. The coordinated sliding groove 212 and sliding shaft 222 enable the gripper 230 to accurately transfer along a preset path, ensuring the welding target reaches the welding station 120 exposed to the laser and then reaches the disassembly / assembly station 110 for safe and reliable disassembly / assembly by the operators. The sliding shaft 222 is positioned and stored by the first positioning groove 213 and the second positioning groove 214, which deviate from the extension trajectory of the sliding groove 212. This effectively stabilizes the position of the gripper 230 at the corresponding station. The elastic element 216, in conjunction with the locking block 217, automatically locks the sliding shaft 222 when it enters the first positioning groove 213. The guide surface 218 improves the stability of the sliding shaft 222 when it enters the sliding groove 212 and the first positioning groove 213. The smooth movement of the gripper 230 into and out of the slots 213 reduces jamming and impact during operation, effectively preventing the gripper 230 from shifting during welding and improving the stability of laser welding. The L-shaped flip groove 211 provides reliable clearance for the flip shaft 221, ensuring smooth flipping. In addition, the quarter-circle slide 212 improves the efficiency of the flipper 220 in switching positions with a single flip, improving assembly and disassembly efficiency and welding efficiency. The flipper 220 can also save space required for device operation by flipping 90 degrees, thus reducing the occupied area and increasing space utilization. The flip shaft 221 and sliding shaft 222 are distributed along the rotation axis of the gripper 230, effectively reducing unnecessary degrees of freedom and improving the rigidity and strength of the overall structure, thus improving structural stability.

[0042] Understandably, the first positioning groove 213 is located on the side of the storage groove 215 near the disassembly / assembly station 110. The first positioning groove 213 extends parallel to the horizontal plane, and its axis is perpendicular to the laser optical axis of the welding station 120. When the sliding shaft 222 is inserted into the first positioning groove 213, the axial freedom of the sliding shaft 222 is forcibly constrained by the mechanical limiting action of the locking block 217, ensuring that the clamping claw 230 is in a zero-gap fixed state at the welding station 120. To avoid micro-displacement caused by welding vibration, the second positioning groove 214 extends perpendicularly to the horizontal plane. The entrance end of the second positioning groove 214 and the end of the slide 212 have a smooth transition. Relying on the principle of gravity self-locking, when the sliding shaft 222 moves along the slide 212 to the entrance of the second positioning groove 214, it automatically slides into the second positioning groove 214 under the action of gravity, so that the clamping claw 230 is accurately positioned at the disassembly and assembly station 110. At this time, the flipping seat 220 is in a vertical state, which facilitates the safe loading and unloading of workpieces by the operator. By combining gravity and elastic locking to restrict and lock the different position states of the sliding shaft 222, the stability of the locking and positioning structure can be improved while effectively simplifying the structure and reducing the cost of the device.

[0043] It is understood that there are two positioning seats 210, and the flip seat 220 is movably inserted between the two positioning seats 210. Both ends of the sliding shaft 222 are provided with threaded parts. The two ends of the sliding shaft 222 are respectively inserted into the corresponding sliding grooves 212 of the two positioning seats 210. The sliding shaft 222 can slide to the corresponding first positioning groove 213 or second positioning groove 214. Each threaded part is threaded with a nut 223. Each nut 223 is located on the side of the two flip seats 220 away from the positioning seat 210. The nut 223 can lock the position of the sliding shaft 222 and the positioning seat 210, thereby locking the relative position between the flip seat 220 and the positioning seat 210. This can effectively improve the stability of the structure during welding and can effectively improve the laser welding accuracy.

[0044] Understandably, the flip base 220 is equipped with a handle 224, which allows for convenient flipping and adjustment of the flip base 220.

[0045] It is understood that the clamping assembly 200 also includes a first x-axis drive module 250 connected to the machine tool 100, a positioning seat 210 connected to the first x-axis drive module 250, and the disassembly station 110 and the welding station 120 are distributed along the extension direction of the x-axis. The first x-axis drive module 250 can further realize the reliable movement of the clamping claw 230 between the disassembly station 110 and the welding station 120, and can effectively improve the flexibility of welding.

[0046] The rotation axis of the gripper 230 is parallel to the x-axis, the flipping axis 221 and the sliding axis 222 are both parallel to the y-axis, the first positioning groove 213 extends along the x-axis direction, and the second positioning groove 214 extends along the z-axis direction. The first x-axis drive module 250 can be configured as a linear drive module such as a rodless cylinder or a lead screw positioning module.

[0047] It is understood that the three-axis positioning mechanism 310 includes a second x-axis drive module 311, a y-axis drive module 312, and a z-axis drive module 313. The second x-axis drive module 311 is connected to the machine base 100, the y-axis drive module 312 is connected to the second x-axis drive module 311, the z-axis drive module 313 is connected to the y-axis drive module 312, and the laser welding head 320 is connected to the z-axis drive module 313. The xy plane is parallel to the horizontal plane, and the z-axis is perpendicular to the horizontal plane.

[0048] By placing the second x-axis drive module 311 and the y-axis drive module 312 in the bottom region, the center of gravity of the three-axis positioning mechanism 310 can be effectively lowered, thereby improving the stability of the overall structure during operation. Furthermore, the lifting in the z-axis direction only requires the gravity of the laser welding head 320 to perform the work, effectively reducing energy consumption. The second x-axis drive module 311, the y-axis drive module 312, and the z-axis drive module 313 can all be configured as linear drive modules such as rodless cylinders or lead screw positioning modules.

[0049] It is understandable that when welding targets with irregular shapes along the welding path, a matching fixture 260 can be used for clamping and positioning. In this embodiment, refer to... Figure 6 As shown, the clamping jaw 230 is connected to the clamp 260, which is used to clamp the welding target. The clamp 260 can be connected to the clamping jaw 230 by a high-rigidity coupling. The coupling is equipped with a cross slider compensation mechanism, which can absorb a certain amount of installation coaxiality deviation and avoid additional bending moment caused by machining errors. A rotating rod 261 is provided on the side of the clamp 260 away from the clamping jaw 230. A support seat 270 is provided on the positioning seat 210. The support seat 270 is provided with a U-shaped groove 271 that matches the rotating rod 261. The U-shaped groove 271 is used to support the rotating rod 261.

[0050] One side of the fixture 260 is positioned by the clamping jaw 230, and the other side of the fixture 260 is positioned by the rotating rod 261 and the U-shaped groove 271. This effectively reduces the positioning burden on the clamping jaw 230. The fixture 260 clamps and positions the welding target from all directions. Moreover, the fixture 260 is positioned by both sides, which can effectively balance the force distribution and improve the stability of the rotation of the fixture 260, thereby improving the reliability of the welding process and achieving high welding precision.

[0051] It is understood that the inner wall of the U-shaped groove 271 is covered with a lubricating layer 272. Preferably, the lubricating layer 272 can be a ceramic layer or a tungsten carbide coating. The ceramic layer can be applied by plasma spraying to prepare an alumina or silicon nitride ceramic coating on the inner wall of the U-shaped groove 271.

[0052] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
