Technical Field
[0001] This utility model relates to the field of titanium metal eyeglasses processing technology, specifically a titanium metal eyeglasses laser welding device. Background Technology
[0002] The titanium metal eyeglass laser welding device is a piece of equipment specifically designed for welding titanium metal eyeglass frames. Its core function is to use the high energy of a laser beam to achieve precise connection of titanium metal components. When it is working, the laser beam is focused on the titanium metal welding area, and the material is melted and cooled and solidified through instantaneous high temperature to form a strong weld. The device has high precision characteristics and can cope with the high hardness and high melting point of titanium metal, ensuring that the welding position error is minimal and avoiding damage to the delicate eyeglass frame structure. At the same time, the laser welding has a small heat-affected zone, which can reduce the deformation of titanium metal and maintain the aesthetics and mechanical properties of the eyeglass frame. It is suitable for welding key parts such as temples and bridges. In the laser welding of titanium metal glasses, although the 1064nm infrared laser is invisible to the naked eye, it will focus on the retina after penetrating the cornea. Its energy can instantly cause photochemical damage or thermal burns, leading to irreversible vision loss or even blindness. Operators must wear protective glasses designed specifically for the 1064nm wavelength. These lenses selectively absorb or reflect the laser through coating technology, controlling the transmitted light intensity within a safe threshold. However, for workers who already wear glasses, wearing protective glasses over their glasses can cause discomfort, limited vision, and reduced operational flexibility, seriously affecting welding efficiency and quality. To solve this problem, existing technologies often use a mounting bracket above the laser welding machine to arrange plate-shaped protective glasses, so that operators do not need to wear additional protective glasses. However, dust generated during the welding process of titanium metal glasses easily adheres to the surface of the protective glass plate, causing a decrease in the light transmittance of the protective glass and affecting the operator's observation of the welding area. Cleaning the dust on the protective glass plate requires stopping the machine, which is not only time-consuming and labor-intensive, but also interrupts the production process and reduces production efficiency. Therefore, a laser welding device for titanium metal glasses is proposed to address the above problems. Utility Model Content

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A laser welding device for titanium metal eyeglasses includes a welding platform 1, a support frame 2 fixed to the top of the welding platform 1, a linear drive motor assembly 3 fixed to the top of the support frame 2, a laser welding head 4 fixed to the moving end of the linear drive motor assembly 3, a cleaning box mechanism 5 fixed above the laser welding head 4 via a mounting bracket, a protective eyeglass assembly 6 mounted above the cleaning box mechanism 5, two support columns 61 with their bottom ends fixedly connected to the two sides of the top of a box body 51, and circulating water pipes 7 fixedly connected to both ends of the box body 51. When the water in the box body 51 needs to be replaced or replenished, it is operated through the circulating water pipes 7. One circulating water pipe 7 is connected to the inlet pipe, and the other circulating water pipe 7 is connected to the outlet pipe, realizing the injection and discharge of clean water in the box body 51 and ensuring water circulation; the protective eyeglass assembly 6 includes two support columns 61, and the inner sides of the two support columns 61 rotate... The support frame 62 has two structural reinforcement rings 63 fixedly connected to its front end. An arc-shaped protective mirror 64 is fixedly connected between the two structural reinforcement rings 63. The support frame 62 is rotatably connected to the support column 61 through a drive assembly 65. The drive assembly 65 includes two drive shafts 651 and a mounting base 655. A force-applying rod 652 is fixedly connected between the two drive shafts 651. The force-applying rod 652 has a bent structure in the middle. An adapter block 653 is fixedly fixed to the front end of the drive shaft 651. A convex ball 654 is fixedly connected to one end of the back of the adapter block 653. The mounting base 655 is fixedly set in the middle of one side of the support column 61. A spring-loaded spring 656 for storing and releasing elastic potential energy is fixedly installed on the inner side of the mounting base 655 to realize automatic reset of the component. A grooved mating cover 657 is engaged with the front end of the mounting base 655. The grooved mating cover 657 is rotatably engaged with the convex ball 654.
[0017] As a further implementation of this solution, the cleaning box mechanism 5 includes a box body 51. Both sides of the top of the box body 51 have clearance grooves 52. The structural reinforcing ring 63 is spaced 5mm from the clearance grooves 52. A cleaning rotating rod 53 is rotatably connected to the bottom inner side of the box body 51. Connecting blocks 54 are fixedly connected to both ends of the cleaning rotating rod 53. The connecting blocks 54 are two-section cylinders. An anti-slip contact block 55 is fixedly connected to one side of the connecting block 54. The anti-slip contact block 55 is located below the structural reinforcing ring 63. The anti-slip contact block 55 and the structural reinforcing ring 63... The components fit together, and symmetrically distributed baffles 56 are fixedly connected to the other side of the connecting block 54. A flexible cleaning brush 57 is fixedly connected to the middle of the cleaning rotating rod 53. The anti-slip contact block 55 on the cleaning rotating rod 53 fits with the structural reinforcement ring 63. When the structural reinforcement ring 63 rotates, the friction drives the cleaning rotating rod 53 to rotate, so that the flexible cleaning brush 57 can brush the arc-shaped protective mirror 64. The baffles 56 at both ends rotate, causing the water in the box to turbulent, enhancing the cleaning effect, ensuring the cleanliness of the arc-shaped protective mirror 64, and improving the protective performance. As a further implementation of this solution, the center of the force-applying rod 652 and the center of the structural reinforcement ring 63 are located on the same central axis, and the center of the drive shaft 651 and the center of the force-applying rod 652 are located on the same central axis. The drive shaft 651 passes through the interior of the mounting base 655 and the interior of the grooved mating cover 657. The drive shaft 651 is rotatably connected to the support column 61. After the operator releases the force-applying rod 652, it can release the elastic potential energy in time, drive the drive shaft 651 to reverse and reset, ensure that the arc-shaped protective mirror 64 automatically returns to its position, and maintain the normal protective function of the device. As a further implementation of this solution, the center of the mounting base 655 and the center of the drive shaft 651 are located on the same central axis. The drive shaft 651 extends to the outside of the support column 61. The inner ring of the spring 656 is fixedly connected to the drive shaft 651. With this configuration, when the operator releases the force bar 652, the spring 656 drives the drive shaft 651 to reverse, thereby automatically resetting the support frame 62, the structural reinforcement ring 63, and the arc-shaped protective mirror 64. As a further implementation of this solution, the center of the grooved cover 657 and the center of the drive shaft 651 are located on the same central axis. The outer side of the grooved cover 657 is provided with a limiting groove 658 distributed in a circular array. The limiting groove 658 fits against the convex ball 654. When the drive shaft 651 rotates in this way, the convex ball 654 slides in the limiting groove 658, generating vibration and transmitting it to the arc-shaped protective mirror 64 to help remove surface deposits. The design of the limiting groove 658 can also limit the convex ball 654, ensuring the stability of the drive shaft 651 during rotation. As a further implementation of this solution, the outer side of the arc-shaped protective mirror 64 has an arc-shaped structure, and the diameter of the arc-shaped protective mirror 64 is adapted to the diameter of the structural reinforcing ring 63. The top of both sides of the support frame 62 is provided with mounting cavities 66. The inner side of the mounting cavity 66 is elastically connected to the snap-fit rod 67 through a return spring. The snap-fit rod 67 is slidably connected to the mounting cavity 66. The front end of the snap-fit rod 67 has an arc-shaped structure and is snapped into the top of the inner side of the support column 61. When the arc-shaped protective mirror 64 is reset, the snap-fit rod 67 is snapped into the top of the support column 61 by the spring force, ensuring that it is stably in the protective position, preventing displacement due to vibration and other factors during the welding process, and ensuring the safety of the operators.
[0018] Workflow: Before laser welding of titanium metal glasses, the device is in its initial state. The locking rod 67 is locked to the top of the support column 61 by the force of the return spring, and the curved protective mirror 64 is stabilized in the protective position to protect against laser radiation. The linear drive motor assembly 3 adjusts the position of the laser welding head 4 via the moving end according to the welding requirements, ready for welding operation. When there is welding dust on the surface of the curved protective mirror 64 that needs to be cleaned, the operator manually applies force to the force rod 652, driving the drive shaft 651 to rotate. The rotation of the drive shaft 651 causes the locking rod 67 to overcome the push force of the return spring and disengage from the support column 61. At the same time, it drives the support frame 62, the structural reinforcement ring 63, and the curved protective mirror 64 to rotate around the drive shaft 651. During the rotation of the drive shaft 651, the adapter block 653 drives the convex ball 654 to rotate. The convex ball 654 slides into contact with the outer limiting groove 658 of the grooved mating cover 657, generating vibration. This vibration is transmitted to the support frame 62 and the curved protective mirror 64 through the drive shaft 651, accelerating the removal of attached materials. Due to the structural reinforcement... As the fixed ring 63 rotates, the structural reinforcement ring 63 and the arc-shaped protective mirror 64 gradually extend into the interior of the box 51 through the clearance groove 52, and come into contact with the rubber anti-slip texture of the anti-slip contact block 55 inside the box 51. This causes the cleaning rotating rod 53 to rotate, which in turn drives the flexible cleaning brush 57 to rotate, brushing the arc-shaped protective mirror 64. The connecting blocks 54 at both ends of the cleaning rotating rod 53 rotate, which drives the symmetrically distributed turbulence blades 56 to rotate, causing the water at the bottom of the inner cavity of the box 51 to form turbulence. The water flow contacts the arc-shaped protective mirror 64 to assist in cleaning. During this process, the spring 656 in the mounting base 655 contracts as the drive shaft 651 rotates. When the arc-shaped protective mirror 64 rotates to its maximum stroke, the operator releases the force rod 652. The spring 656 drives the drive shaft 651 to reverse, causing the support frame 62, the structural reinforcement ring 63, and the arc-shaped protective mirror 64 to automatically reset. The locking rod 67 re-engages with the top of the support column 61 by the force of the reset spring, and the device returns to its initial protective state, allowing welding to continue.
[0019] 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.
