Description

Technical Field

[0001] This utility model relates to the field of laser welding protection technology, specifically a protective mechanism for platform laser welding. Background Technology

[0002] Laser welding is a welding technology that uses a high-energy-density laser beam as a heat source to locally melt and rapidly solidify the materials being welded, thus achieving a connection. Its core principle is to focus the laser beam to form a tiny spot, releasing energy instantaneously so that the materials reach the welding temperature in a very short time.

[0003] Compared to traditional welding, it has a smaller heat-affected zone and lower deformation, enabling precise welding of thin materials or complex structures. Moreover, it does not require contact with the workpiece, making it suitable for precision components. Currently, it is widely used in fields such as automotive manufacturing (e.g., battery tab welding), electronics industry (chip wire bonding), and medical devices (implant connection). With its high efficiency and high precision, it has become one of the key technologies for high-end manufacturing.

[0004] Chinese Utility Model Patent Publication No. CN220259866U discloses a highly stable integrated laser welding platform. The specification of this highly stable integrated laser welding platform solves the problem that the vibration generated by the cooling water tank during operation affects the stability of the laser welding platform. It has a highly stable working environment. However, it does not have a liftable infrared grating, and cannot stop the machine in time, which can easily lead to personnel errors and injuries, posing certain safety hazards. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a protective mechanism for platform laser welding, thereby resolving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for platform laser welding, comprising a laser stage and a three-axis module moving assembly and a workpiece clamping assembly located on the upper part of the laser stage. A laser welding head is fixedly installed on the top of the laser stage via the three-axis module moving assembly. The workpiece clamping assembly is located below the laser welding head. Through slots are provided at the four corners inside the laser stage. A lower support is fixedly installed inside the laser stage. A direct-connect servo linear slide is fixedly installed inside the laser stage via the lower support. A slider is slidably installed on the outer side of the direct-connect servo linear slide. A connecting frame is fixedly installed on the outer side of the slider. An infrared grating is fixedly installed on the top of the connecting frame.

[0007] Preferably, the three-axis module moving assembly includes an X-axis moving module, a Y-axis moving module is fixedly mounted on the movable end of the X-axis moving module, a Z-axis moving module is fixedly mounted on the movable end of the Y-axis moving module, an ear is fixedly mounted on the movable end of the Z-axis moving module, a servo motor is fixedly mounted on the top of the ear, a connecting rod is fixedly mounted on the output shaft of the servo motor, and the end of the connecting rod away from the servo motor is fixedly connected to the laser welding head.

[0008] Through the above technical solution, the laser welding head can move flexibly in the X, Y, and Z directions. At the same time, the servo motor can drive the laser welding head to rotate, thereby realizing the angle adjustment of the laser welding head, thus meeting the welding needs of different positions and angles, and improving the flexibility and accuracy of welding.

[0009] Preferably, there are two identical X-axis moving modules, which are symmetrically distributed at the bottom of the Y-axis moving module.

[0010] Through the above technical solution, the two symmetrically distributed X-axis moving modules can provide stable support for the Y-axis moving module, effectively distribute the load, prevent the Y-axis moving module from shaking during movement, ensure the smoothness of the laser welding head movement, and thus improve the welding accuracy.

[0011] Preferably, the workpiece clamping assembly is located in the middle of the top of the laser stage, the workpiece clamping assembly is located between two X-axis moving modules, and a controller is provided at the front of the laser stage.

[0012] With the above technical solution, the workpiece clamping assembly is located in the middle of the top of the laser stage and between the two X-axis moving modules, which can keep the workpiece within the optimal working range of the laser welding head and improve the stability during welding.

[0013] Preferably, the lower support, direct-connect servo linear slide, slider, connecting frame and infrared grating are all provided in two identical sets, and each set of the lower support, direct-connect servo linear slide, slider, connecting frame and infrared grating is provided in two identical sets.

[0014] Through the above technical solution, the two sets of four infrared gratings can form a three-dimensional protection area from different directions, expanding the protection range and reducing blind spots.

[0015] Preferably, the infrared grating is located inside the through groove, the infrared grating and the through groove are slidably connected, and the infrared grating and the through groove do not contact each other.

[0016] Through the above technical solution, the infrared grating can slide inside the through groove. When not in use, the infrared grating can be stored inside the through groove to reduce space occupation. When in use, the infrared grating can rise under the drive of the direct-connected servo linear slide, slider and connecting frame.

Combined with the stable support of the two X-axis moving modules, it effectively improves the accuracy and flexibility of welding, can adapt to welding needs at different positions and angles, and enhances its practicality.

[0019] 2. The laser welding protective mechanism of this platform is equipped with two sets of four identical infrared gratings to form a three-dimensional protective area, which greatly expands the protection range, reduces blind spots, and improves operational safety, providing efficient protection. At the same time, the sliding connection design between the infrared gratings and the through slots allows for flexible adjustment of the position of the infrared gratings. When not in use, they can be stored away, adapting to different operational needs while saving space. The overall design is reasonable and provides good protection, reducing the occurrence of injuries to operators due to errors. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figure 1-7 As shown, the present invention provides a protective mechanism for platform laser welding, including a laser table 1, a three-axis module moving assembly 2 and a workpiece clamping assembly 3 located on the upper part of the laser table 1. A laser welding head 12 is fixedly installed on the top of the laser table 1 through the three-axis module moving assembly 2. The workpiece clamping assembly 3 is located below the laser welding head 12. Through slots 5 are opened at the four corners inside the laser table 1. A lower support 6 is fixedly installed inside the laser table 1. A direct-connect servo linear slide 7 is fixedly installed inside the laser table 1 through the lower support 6. A slider 8 is slidably installed on the outside of the direct-connect servo linear slide 7. A connecting frame 9 is fixedly installed on the outside of the slider 8. An infrared grating 10 is fixedly installed on the top of the connecting frame 9.

[0031] Example 2:

[0032] like Figure 2-7 As shown, as an improvement to the previous embodiment, this is done to meet the welding requirements at different angles.

[0033] Specifically, the three-axis module moving assembly 2 includes an X-axis moving module 201, a Y-axis moving module 202 fixedly mounted on the movable end of the X-axis moving module 201, a Z-axis moving module 203 fixedly mounted on the movable end of the Y-axis moving module 202, an ear seat 204 fixedly mounted on the movable end of the Z-axis moving module 203, a servo motor 205 fixedly mounted on the top of the ear seat 204, a connecting rod 207 fixedly mounted on the output shaft of the servo motor 205, and the end of the connecting rod 207 away from the servo motor 205 being fixedly connected to the laser welding head 12. Two identical X-axis moving modules 201 are provided, and the two X-axis moving modules 201 are symmetrically distributed at the lower part of the Y-axis moving module 202. Specifically, the workpiece clamping assembly 3 is located in the middle of the top of the laser stage 1, between the two X-axis moving modules 201, and a controller 4 is provided at the front of the laser stage 1. The advantages are that the laser welding head 12 can move flexibly in the X, Y, and Z directions, and the servo motor 205 can drive the laser welding head 12 to rotate, thereby realizing the angle adjustment of the laser welding head 12, which can meet the welding needs of different positions and angles, improve the flexibility and accuracy of welding. The two symmetrically distributed X-axis moving modules 201 can provide stable support for the Y-axis moving module 202, effectively distribute the load, and avoid the Y-axis moving module 202 from shaking during movement, ensuring the smooth movement of the laser welding head 12, thereby improving the welding accuracy. The workpiece clamping component 3 is located at the top center of the laser stage 1 and between the two X-axis moving modules 201, which can keep the workpiece within the optimal working range of the laser welding head 12, improving the stability during welding.

[0034] Example 3:

[0035] like Figure 2-7 As shown, as an improvement on the previous embodiment, the device's protective performance is enhanced.

[0036] Specifically, the lower support 6, the direct-connect servo linear slide 7, the slider 8, the connecting frame 9, and the infrared grating 10 are all equipped with two identical sets, with each set containing two identical sets of the same components. The advantage is that the two sets, totaling four infrared gratings 10, can form a three-dimensional protective area from different directions, expanding the protection range and reducing blind spots.

[0037] Specifically, the infrared grating 10 is located inside the through groove 5, and the infrared grating 10 and the through groove 5 are slidably connected, without contacting each other. The advantage is that the infrared grating 10 can slide inside the through groove 5, and when not in use, it can be stored inside the through groove 5, reducing space occupation. When in use, the infrared grating 10 can rise under the drive of the direct-connected servo linear slide 7, slider 8, and connecting bracket 9.

[0038] Working Principle: During use, the operator first places the workpiece to be welded on the workpiece clamping assembly 3. The workpiece is securely clamped by the workpiece clamping assembly 3. After the workpiece to be welded is clamped, the equipment is started. The three-axis module moving assembly 2 starts working. The X-axis moving module 201, Y-axis moving module 202, and Z-axis moving module 203 work together to move the laser welding head 12 in the X, Y, and Z directions. At the same time, the servo motor 205 drives the connecting rod 207 to rotate, thereby adjusting the angle of the laser welding head 12 so that it is accurately aligned with the welding position of the workpiece for welding. At the same time as the laser welding head 12 starts welding, the direct-connect servo linear slide 7 starts. The infrared grating 10 slides upward from the through slot 5 through the slider 8 and the connecting frame 9. Since there are two sets of four infrared gratings 10 in the lower bracket 6, the direct-connect servo linear slide 7, and other components, the four infrared gratings 10 extend from the four corners of the laser table 1 to form a three-dimensional protective area, which monitors the welding operation area in all directions to ensure operation safety and play an efficient protective role.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
