技术领域Technical Field
本发明属于振镜技术领域，尤其涉及一种超高速数字激光振镜驱动装置。The invention belongs to the technical field of galvanometers, and in particular relates to an ultra-high-speed digital laser galvanometer driving device.
背景技术Background Art
超高速数字激光振镜驱动装置主要由反射镜片、驱动装置（包括电磁驱动或压电驱动等）、控制器及相关的电子元件组成。其中，反射镜片负责反射激光束，而驱动装置则通过精确控制电流或电压的变化，使反射镜片产生快速且准确的偏转。The ultra-high-speed digital laser galvanometer drive device is mainly composed of a reflective lens, a drive device (including electromagnetic drive or piezoelectric drive, etc.), a controller and related electronic components. Among them, the reflective lens is responsible for reflecting the laser beam, and the drive device precisely controls the change of current or voltage to make the reflective lens produce fast and accurate deflection.
现有技术中公开了部分振镜技术领域的中国专利，其中申请号为CN202021509433.7的中国专利，公开了一种振镜驱动装置及激光加工系统，通过将固定件夹设于第一导向件和第二导向件之间，且固定件通过滚动组件与第一导向件、第二导向件滚动配合，因此凸轮旋转进而带动固定件在第一导向件和所述第二导向件滚动以进行往复直线移动，滚动的移动方式阻力更小，可以减小振镜电机的负载，且能够避免固定件在相对第一导向件、第二导向件移动时产生的磨损，此外，将固定件夹设于第一导向件和第二导向件之间，能够使滚动组件与第一导向件、第二导向件接触紧密，提高固定件的运动稳定性，从而使整个运动系统的刚性提升，且能有效地提升系统的响应速度。总之，该振镜驱动装置具有结构简单、运行稳定性好、负载重量轻、刚性强度好、响应速度快的特点。Some Chinese patents in the field of galvanometer technology are disclosed in the prior art, among which the Chinese patent with application number CN202021509433.7 discloses a galvanometer drive device and a laser processing system, wherein a fixed part is clamped between the first guide and the second guide, and the fixed part is rolled with the first guide and the second guide through a rolling assembly, so that the cam rotates and drives the fixed part to roll on the first guide and the second guide to perform reciprocating linear movement, and the rolling movement mode has less resistance, which can reduce the load of the galvanometer motor and avoid the wear of the fixed part when it moves relative to the first guide and the second guide. In addition, the fixed part is clamped between the first guide and the second guide, so that the rolling assembly can be in close contact with the first guide and the second guide, and the motion stability of the fixed part is improved, thereby improving the rigidity of the entire motion system and effectively improving the response speed of the system. In short, the galvanometer drive device has the characteristics of simple structure, good operation stability, light load weight, good rigidity and fast response speed.
现有技术通过滚动组件、第一导向件及第二导向件实现了振镜的运动，但是在超高速的运动下，会产生高温，高温会导致滚动组件和导向组件的材料性能发生变化，如硬度降低、弹性模量变化等，进而影响其运动的精确性和稳定性，同时高温会引起组件的热膨胀，导致滚动和导向间隙的变化，从而影响振镜的定位精度和重复定位精度。The prior art realizes the movement of the galvanometer through a rolling assembly, a first guide member and a second guide member. However, under ultra-high-speed movement, high temperature will be generated. The high temperature will cause changes in the material properties of the rolling assembly and the guide assembly, such as reduced hardness, changes in elastic modulus, etc., thereby affecting the accuracy and stability of its movement. At the same time, high temperature will cause thermal expansion of the assembly, resulting in changes in the rolling and guide gaps, thereby affecting the positioning accuracy and repeatability of the galvanometer.
基于此，本发明设计了一种超高速数字激光振镜驱动装置，以解决上述问题。Based on this, the present invention designs an ultra-high-speed digital laser galvanometer driving device to solve the above problems.

综上所述，由于采用了上述技术方案，本发明的有益效果是：In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
1、本发明中，通过设置冷却导向管，通过在冷却导向管内注入流动的水，同时通过流动的水能够带动螺旋刮壁杆及风叶转动，能够避免冷却导向管内壁的水垢的附着，保证其导热效率，同时能够加快设备内的空气流动，此时在驱动架在冷却导向管上进行高速运动时，能够迅速吸收并带走驱动架在高速运动中产生的大量热量，从而有效防止设备过热，从而延长设备的使用寿命，减少因过热而导致的故障和维修成本，同时，稳定的工作温度也有助于提高激光振镜的加工精度和稳定性，确保产品质量。1. In the present invention, a cooling guide tube is provided and flowing water is injected into the cooling guide tube. The flowing water can drive the spiral scraper rod and the fan blades to rotate, thereby avoiding the adhesion of scale on the inner wall of the cooling guide tube, ensuring its thermal conductivity, and accelerating the air flow in the equipment. At this time, when the driving frame moves at high speed on the cooling guide tube, it can quickly absorb and take away a large amount of heat generated by the driving frame during the high-speed movement, thereby effectively preventing the equipment from overheating, thereby extending the service life of the equipment and reducing failures and maintenance costs caused by overheating. At the same time, a stable working temperature also helps to improve the processing accuracy and stability of the laser galvanometer and ensure product quality.
2、本发明中，通过设置动磁铁、定磁铁及电磁线圈，当电流通过线圈时，产生的磁场会与定磁铁的磁场叠加或抵消，导致动磁铁所受的排斥力发生变化，通过精确控制线圈中的电流大小和方向，可以实现对动磁铁位置的精确控制，进而驱动振镜进行快速而准确的偏转，相比传统的振镜电机驱动方式具有响应速度快、精度高、噪音低、能耗低和维护成本低等优点。2. In the present invention, by setting a moving magnet, a fixed magnet and an electromagnetic coil, when current passes through the coil, the generated magnetic field will be superimposed or offset with the magnetic field of the fixed magnet, resulting in a change in the repulsive force on the moving magnet. By accurately controlling the magnitude and direction of the current in the coil, the position of the moving magnet can be accurately controlled, thereby driving the galvanometer to deflect quickly and accurately. Compared with the traditional galvanometer motor drive method, it has the advantages of fast response speed, high precision, low noise, low energy consumption and low maintenance cost.
3、本发明中，通过设置防护机构，能够在不使用振镜时将其进行密封防护避免受潮、受尘或受其他形式的物理损害，同时在海绵擦的作用下，及时清理振镜和光学元件上的尘埃和污垢，保持其表面清洁，确保其稳定、高效、精确地运行。3. In the present invention, by providing a protective mechanism, the galvanometer can be sealed and protected when not in use to avoid moisture, dust or other forms of physical damage. At the same time, with the help of a sponge, dust and dirt on the galvanometer and optical elements can be cleaned in time to keep their surfaces clean, thereby ensuring stable, efficient and precise operation.

工作原理，使用时：需要将需的部件安装到外壳1内，首先将定磁铁7及动磁铁6分别安装在外壳1内及驱动架3上的磁铁安装机构5上，通过将定磁铁7放置到安装座501内后，通过人工手动转动调节杆507，使得调节杆507带动连接的推杆508移动，此时推杆508会接触并挤压三角块509，使得三角块509带动连接的移动盘504进行移动，此时移动盘504上的齿条506会带动齿轮503连接的限位杆502转动，对定磁铁7进行夹持安装；Working principle: when in use: the required components need to be installed in the housing 1, first, the fixed magnet 7 and the moving magnet 6 are respectively installed in the housing 1 and on the magnet mounting mechanism 5 on the driving frame 3, after the fixed magnet 7 is placed in the mounting seat 501, the adjusting rod 507 is manually rotated so that the adjusting rod 507 drives the connected push rod 508 to move, at this time the push rod 508 will contact and squeeze the triangular block 509, so that the triangular block 509 drives the connected moving disk 504 to move, at this time the rack 506 on the moving disk 504 will drive the limit rod 502 connected to the gear 503 to rotate, and the fixed magnet 7 is clamped and installed;
然后将振镜主体4上的插杆401插入到插接孔303内，此时弹簧403会使得限位块402与插接孔303活动卡接，完成对振镜主体4的安装，然后根据需要控制电流，当电流通过电磁线圈8时，产生的磁场会与定磁铁7的磁场叠加或抵消，导致动磁铁6受的排斥力发生变化，通过精确控制电磁线圈8中的电流大小和方向，可以实现对动磁铁6位置的精确控制，进而使得驱动架3两端的导向环301内的滚轮302在冷却导向管2外壁滚动，从而驱动振镜主体4进行快速而准确的偏转；Then, the insertion rod 401 on the galvanometer body 4 is inserted into the insertion hole 303. At this time, the spring 403 will make the limit block 402 and the insertion hole 303 movably engage, completing the installation of the galvanometer body 4. Then, the current is controlled as needed. When the current passes through the electromagnetic coil 8, the magnetic field generated will be superimposed or offset with the magnetic field of the fixed magnet 7, resulting in a change in the repulsive force on the moving magnet 6. By accurately controlling the magnitude and direction of the current in the electromagnetic coil 8, the position of the moving magnet 6 can be accurately controlled, thereby making the rollers 302 in the guide rings 301 at both ends of the drive frame 3 roll on the outer wall of the cooling guide tube 2, thereby driving the galvanometer body 4 to deflect quickly and accurately.
同时通过管接头201与外部水源连通，此时流动的水在进入到冷却导向管2内会对滚轮302移动时产生的热量进行带走，同时流动的水会带动叶轮203转动，此时叶轮203会带动万向节A208连接的风叶209转动，加快空气流动，实现了对电磁线圈8的散热，同时叶轮203会带动连接杆204连接的螺旋刮壁杆205进行周转，此时在环形齿条207的作用下，会使得传动轮206连接的螺旋刮壁杆205进行自转，对附着在冷却导向管2内壁的水垢进行去除，保证其导热性；At the same time, it is connected with an external water source through the pipe joint 201. At this time, the flowing water enters the cooling guide pipe 2 to take away the heat generated when the roller 302 moves. At the same time, the flowing water drives the impeller 203 to rotate. At this time, the impeller 203 drives the fan blade 209 connected to the universal joint A208 to rotate, thereby accelerating the air flow and achieving the heat dissipation of the electromagnetic coil 8. At the same time, the impeller 203 drives the spiral scraper rod 205 connected to the connecting rod 204 to rotate. At this time, under the action of the annular rack 207, the spiral scraper rod 205 connected to the transmission wheel 206 will rotate, thereby removing the scale attached to the inner wall of the cooling guide pipe 2, thereby ensuring its thermal conductivity.
在振镜主体4使用完毕后，通过转动双向丝杆901，使得双向丝杆901带动两个移动块903移动，此时移动块903上的移动架904会带动防护盖905移动，此时在固定齿条A101的作用下，会使得调节轮908带动连接的蜗杆907转动，使得蜗杆907带动蜗轮906连接的防护盖905竖起，然后在防护盖905上的海绵擦910接触到振镜主体4时，在固定齿条B102的作用下，会使得驱动轮911转动，从而带动万向节B909连接的海绵擦910转动，对振镜主体4表面进行清洁，然后防护盖905盖在振镜主体4两侧对其进行防护。After the use of the galvanometer body 4 is completed, the bidirectional screw rod 901 is rotated to drive the two moving blocks 903 to move. At this time, the moving frame 904 on the moving block 903 will drive the protective cover 905 to move. At this time, under the action of the fixed rack A101, the adjusting wheel 908 will drive the connected worm 907 to rotate, so that the worm 907 drives the protective cover 905 connected to the worm wheel 906 to stand up. Then, when the sponge 910 on the protective cover 905 contacts the galvanometer body 4, under the action of the fixed rack B102, the driving wheel 911 will rotate, thereby driving the sponge 910 connected to the universal joint B909 to rotate, and the surface of the galvanometer body 4 is cleaned. Then, the protective cover 905 is covered on both sides of the galvanometer body 4 to protect it.
