Technical Field
[0001] This utility model relates to the field of laser welding head technology, and in particular to an adjustment structure for mounting collimating lenses in a laser welding head. Background Technology
[0002] In the field of laser welding, the collimating lens mounting and adjustment structure of the laser welding head plays a crucial role. As a key component determining the laser beam quality and spot position, the accuracy and ease of installation and adjustment of the collimating lens directly affect the quality and efficiency of laser welding. With the widespread application of laser welding technology in many industries such as electronics, automotive, and aerospace, the performance requirements for the collimating lens mounting and adjustment structure of the welding head are also increasing.
[0003] Currently, the most common method for mounting collimating lenses in laser welding heads is to use a pressure ring for fixing. This method uses a threaded pressure ring to press the lens firmly into a specific mounting groove. The technical principle of this mounting method is mainly based on mechanical clamping force, aiming to securely fix the lens in the welding head, ensuring that the lens does not shift during welding, thereby maintaining the collimation of the laser beam.
[0004] Existing adjustment structures for mounting collimating lenses in laser welding heads require specialized tools to unscrew each screw when replacing the collimating lens. This process is not only time-consuming and labor-intensive, but also prone to stripping the screws during repeated unscrewing, further increasing the difficulty of disassembly. Therefore, an adjustment structure for mounting collimating lenses in laser welding heads is proposed to solve the above problems. Utility Model Content

[0023] The above-mentioned technical solutions in the adjustment structure for mounting the collimating lens of the laser welding head provided in this embodiment of the utility model have at least one of the following technical effects:
[0024] 1. In this utility model, by squeezing the squeezing block, it slides into the fixed cover, thereby squeezing the fixed block to release it from the inside of the mounting sleeve, achieving a quick disassembly effect. This solves the problem that when the collimating lens of some laser welding heads needs to be replaced, the threaded connection requires the use of special tools to unscrew the screws one by one.

[0036] Reference Figures 1-2This utility model provides an embodiment of an adjustment structure for mounting a collimating lens in a laser welding head, including a locking seat 1. A connecting cylinder 2 is fixedly connected to the lower surface of the locking seat 1. A mounting sleeve 3 is slidably connected to the side wall of the connecting cylinder 2. The mounting sleeve 3 supports the collimating lens body 4. The collimating lens body 4 is disposed inside the mounting sleeve 3. A fixing component is disposed on the side wall of the connecting cylinder 2. An adjustment component is disposed inside the mounting sleeve 3. The fixing component is used to prevent the mounting sleeve 3 from sliding during operation, ensuring the stability of the position of the collimating lens body 4. The fixing component includes a fixing block 6. A spring 5 is fixedly connected to the side wall of the fixing block 6. The end is fixedly connected inside the connecting cylinder 2. The side wall of the fixing block 6 is slidably connected inside the connecting cylinder 2. The side wall of the mounting sleeve 3 is fixedly connected to the fixing cover 7. The fixing cover 7 is mainly used to protect the internal extrusion block 8 and the limiting ring 9. It also provides a sliding track for the extrusion block 8. The extrusion block 8 is slidably connected inside the fixing cover 7. The extrusion block 8 is used to extrude the fixing block 6 when the position of the mounting sleeve 3 needs to be adjusted. The side wall of the extrusion block 8 is fixedly connected to the limiting ring 9. The function of the limiting ring 9 is to prevent the extrusion block 8 from sliding out of the fixing cover 7. The side wall of the fixing block 6 is slidably connected inside the mounting sleeve 3. The side wall of the limiting ring 9 is slidably connected inside the fixing cover 7.
[0037] During the use of this device, when it is necessary to disassemble the collimating lens body 4, firstly, press the squeezing block 8. When the squeezing block 8 slides into the fixing cover 7, it squeezes the fixing block 6. The fixing block 6 was originally stuck inside the mounting sleeve 3 under the action of the spring 5. At this time, the squeezing action of the squeezing block 8 causes the fixing block 6 to slide into the connecting cylinder 2, while squeezing the spring 5. The spring 5 is elastic and stores elastic potential energy when squeezed. Its function is to provide elastic force to keep the fixing block 6 in the locked position under normal working conditions, while squeezing the squeezing block 8 out of the fixing cover 7. When disassembling, it can also be squeezed by the squeezing block 8. The compression of the lower part provides space for the retraction of the fixing block 6. Through this operation, the fixing block 6 releases the fixing effect on the mounting sleeve 3. At this time, the connection between the mounting sleeve 3 and the connecting cylinder 2 is released. Since the side wall of the mounting sleeve 3 and the connecting cylinder 2 are slidably connected, the mounting sleeve 3 can be separated from the connecting cylinder 2 by pulling it downward. After the mounting sleeve 3 is separated from the connecting cylinder 2, the collimating lens body 4 inside can be taken out for cleaning and replacement. Through the coordinated work of the above series of components, it can be taken out conveniently and quickly, meeting the needs of maintenance and replacement, and ensuring that the laser welding head always maintains good working performance.
[0038] Reference Figure 3The adjustment assembly includes a sliding ring 10, with a slider 11 fixedly connected to the side wall of the sliding ring 10. The slider 11 is slidably connected to the inside of the mounting sleeve 3, providing guidance for the movement of the sliding ring 10. The side wall of the slider 11 is slidably connected to the inside of the mounting sleeve 3. A sliding block 15 is fixedly connected to the side wall of the sliding ring 10, and the side wall of the sliding block 15 is slidably connected to the inside of the mounting sleeve 3. A spring 12 is fixedly connected to the lower surface of the connecting cylinder 2. The collimating lens body 4 is pressed against the upper surface of the sliding ring 10 by a pressure ring 13, ensuring the stability of the collimating lens body 4 inside the mounting sleeve 3 and preventing it from shaking due to vibration or other external forces during operation. One end of the spring 12 is fixedly connected to the pressure ring 13, which directly acts on the collimating lens body 4. The sidewall of the collimating lens body 4 is attached to the upper surface of the sliding ring 10, and the sidewall of the collimating lens body 4 is attached to the lower surface of the pressure ring 13. This attachment method achieves stable fixation of the collimating lens body 4 between the sliding ring 10 and the pressure ring 13. The sidewall of the mounting sleeve 1 3 is fixedly connected to the mounting sleeve 2 14, which provides a support structure for the installation and rotation of the screw 16. The sidewall of the sliding block 15 is slidably connected inside the mounting sleeve 2 14, and the screw 16 is rotatably connected inside the mounting sleeve 2 14. The upper surface of the screw 16 is fixedly connected to the rotating handle 17, which provides a force application point for the operator. The internal thread of the sliding block 15 is threaded to the sidewall of the screw 16. Through the thread design, the movement distance of the sliding block 15 can be controlled, thereby achieving the adjustment of the position of the collimating lens body 4.
[0039] During equipment use, when it is necessary to adjust the collimation of the laser beam, first remove the locking seat 1 from inside the laser welding equipment. Then, rotate the handle 17. The resulting rotation will drive the screw 16 to rotate. The screw 16 is fixedly connected to the handle 17, transmitting the rotational motion of the handle 17. Since the sliding block 15 and the screw 16 are threadedly connected, when the screw 16 rotates, the sliding block 15 will slide under the action of the thread. The sliding of the sliding block 15 will then drive the sliding ring 10 to slide inside the mounting sleeve 3. The sliding ring 10 serves to connect the sliding block 15 and the collimating lens body 4, transmitting the linear motion of the sliding block 15 to the collimating lens body 4. At the same time, the mounting sleeve 3 provides a stable sliding track for the sliding ring 10, ensuring that the sliding ring 10 will not deviate or wobble during the sliding process, thus ensuring collimation. The adjustment precision of the collimating lens body 4 is achieved by sliding the sliding ring 10 upwards, allowing the collimating lens body 4 to move vertically and thus adjust the collimation of the laser beam. As the collimating lens body 4 slides upwards, the pressure ring 13 compresses the spring 12. The spring 12, originally in its natural state, provides downward pressure to the collimating lens body 4, ensuring its stability during normal operation. During adjustment, the spring 12 is compressed, storing elastic potential energy. Its function is not only to provide reverse resistance during adjustment, making the adjustment process smoother, but also to continuously provide pressure after adjustment, ensuring the collimating lens body 4 remains stable in the new position. This achieves the effect of adjusting the collimating lens body 4 up and down, thus realizing precise adjustment of the laser beam collimation.
[0040] Working principle: When using this equipment, if it is necessary to disassemble the collimating lens body 4, first press the squeezing block 8 to slide it into the fixing cover 7, thereby squeezing the fixing block 6 and making it slide into the connecting cylinder 2, squeezing the spring 5, thus releasing the fixing block 6. At this time, by pulling down the mounting sleeve 3, it can be separated from the connecting cylinder 2, so that the collimating lens body 4 inside can be taken out for cleaning and replacement. During the use of the equipment, when it is necessary to adjust the collimation of the laser beam, the locking seat 1 is taken out from the laser welding equipment, and then the rotating handle 17 is rotated. The resulting rotation will drive the screw 16 to rotate, and the sliding block 15 slides on it through the threaded connection with the screw 16, thereby driving the sliding ring 10 to slide inside the mounting sleeve 3, thereby pushing the collimating lens body 4 to slide upward, so that the pressure ring 13 squeezes the spring 12, achieving the effect of adjusting the collimating lens body 4 up and down.
[0041] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
