Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of engraving machine technology, and more specifically, to a three-axis CNC engraving machine for the production of sensitive components. Background Technology

[0002] Against the backdrop of the booming development of modern manufacturing, sensitive components, as key basic components in various electronic devices, industrial control systems, medical instruments and aerospace and other high-end fields, are in increasing demand, and the requirements for product precision, quality and performance are becoming more and more stringent. In the production process of sensitive components, engraving is an extremely important link, which requires high precision and high complexity of pattern and structure engraving within a small size range, which puts extremely high demands on the precision, stability and flexibility of processing equipment.

[0003] Looking at the development history of the engraving machine industry, early three-axis machining machines could "carve" three surfaces simultaneously using three linear axes. However, when dealing with sensitive components with complex shapes, frequent flipping was required, which not only led to low processing efficiency but also resulted in a large accumulation of geometric tolerances due to multiple clamping operations, making it difficult to improve processing accuracy and meet the ever-increasing high-precision requirements of sensitive components. With the high-end development of the manufacturing industry, especially the rise of high-end industries such as aerospace, many key parts have complex curved surfaces and polyhedral shapes, and the precision requirements are almost demanding. This has prompted processing equipment to break through to more "dimensions," and five-axis or even higher axis machining centers have emerged. However, although multi-axis machining centers can improve the complexity of processing, the equipment cost is high. For example, the five-axis machining equipment introduced by some domestic mold companies costs more than 10 million yuan per unit. At the same time, its operation and programming are extremely difficult, requiring professional programmers to learn and master it. This undoubtedly increases the technical threshold and labor costs for enterprises.

[0004] Focusing on the production of sensitive components, which is inherently unique, there are many types of sensitive components, including common types such as sound, force, light, magnetism, gas, temperature and humidity. Each type of sensitive component has a different structure, size and function. During production, the engraving machine needs to have a high degree of flexibility and precise positioning control to meet diverse processing needs. In addition, sensitive components are often tiny, at the millimeter or even micrometer level. This requires that the debris and impurities generated during the engraving process must be cleaned up in a timely manner, otherwise it is very likely to contaminate the processing area and affect the performance of the sensitive component and the yield.

[0005] A review of existing engraving equipment used for sensitive component production reveals numerous problems. In terms of mechanical transmission, traditional transmission structures struggle to achieve high-precision positioning control while maintaining high-speed operation, easily leading to accuracy deviations due to vibration and wear. Regarding CNC control, some CNC systems cannot accurately interpret complex machining programs, causing deviations between the engraving head's trajectory and the preset path, hindering the precise engraving of sensitive components. In terms of processing environment cleanliness, most equipment lacks effective table cleaning mechanisms, resulting in debris and impurities accumulating on the processing table, affecting subsequent processing accuracy and potentially damaging sensitive components due to electrostatic adsorption. Therefore, developing a three-axis CNC engraving machine specifically designed for sensitive component production, featuring high-precision mechanical transmission, intelligent CNC control, and efficient table cleaning functions, is an urgent task to meet current sensitive component production needs and promote the development of related industries.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the three-axis CNC engraving machine significantly improves processing accuracy and stability through optimized multi-directional drive component design. The precise coordination of the translation drive screw, longitudinal drive screw, output motor, and drive motor, along with the limiting and guiding structure composed of sliding limit plates, sliding grooves, and sliding wheels, effectively reduces vibration and offset during movement. When engraving sensitive components, it can precisely control the movement trajectory of the engraving head, avoiding accuracy deviations caused by transmission errors. The processing accuracy can be controlled within a very small error range, meeting the stringent high-precision requirements of sensitive components. At the same time, the micro-adjustment function of the telescopic cylinder for the height of the engraving head further enhances the adaptability to sensitive components of different thicknesses, ensuring the consistency of engraving depth, thereby improving product quality and yield, and reducing scrap rate and rework costs caused by insufficient processing accuracy.

[0021] 2. In this disclosure, the design of the table cleaning component achieves efficient cleaning of the processing table. The coordinated work of the spray brush head, comb-shaped mounting platform, residue filter, and drain port can promptly clean up debris and impurities generated during or after engraving, preventing contamination of the processing area and avoiding performance degradation or damage to sensitive components due to debris residue. This ensures a clean production environment for sensitive components and improves product reliability. Compared to multi-axis machining centers, this three-axis CNC engraving machine meets most processing needs for sensitive components while significantly reducing equipment costs. Furthermore, its operation and programming are relatively simple, lowering the technical threshold and labor costs for enterprises. The efficient cleaning function reduces the time and cost of manual cleaning, enabling enterprises to improve production efficiency, reduce overall production costs, and enhance market competitiveness while ensuring product quality.

[0034] like Figures 1-4 As shown, a three-axis CNC engraving machine for producing sensitive components according to this disclosure is illustrated, comprising:

[0035] A processing table 1 is provided with a support frame 2 on its lower end surface;

[0036] Multi-directional drive component 3 is mounted on the machining table 1;

[0037] Tabletop cleaning component 4 is installed on the upper surface of the processing table 1;

[0038] The multi-directional drive assembly 3 includes a drive frame 3-1, which is disposed on opposite side walls of the support frame 2. A translation drive screw 3-2 is disposed on the inner side wall of the drive frame 3-1. An output motor 3-3 is disposed on the side wall of the translation drive screw 3-2. The output motor 3-3 is disposed on the side wall of the drive frame 3-1. A translation frame 3-4 is fitted on the upper meshing sleeve of the translation drive screw 3-2. A drive table 3-5 is disposed on the upper end face of the translation frame 3-4. A mounting frame 3-6 is disposed on the side wall of the drive table 3-5. A drive motor 3-7 is disposed on the mounting frame 3-6. A longitudinal drive screw 3-8 is connected to the drive motor 3-7. A sliding table 3-9 is disposed on the longitudinal drive screw 3-8. A carving head 3-10 is disposed at the lower end of the sliding table 3-9.

[0039] The countertop cleaning component 4 includes a cleaning tank 4-1, which is located on the upper surface of the processing table 1. A comb-shaped mounting platform 4-2 is provided inside the cleaning tank 4-1. A spray brush head 4-3 is provided on the side wall of the cleaning tank 4-1 and is aligned with the comb-shaped mounting platform 4-2. A drain port 4-4 is provided on the side wall of the cleaning tank 4-1.

[0040] In some examples, the three-axis CNC engraving machine for producing this sensitive element mainly consists of a processing table 1, a multi-directional drive assembly 3, and a table cleaning assembly 4. The lower end of the processing table 1 is stably supported by a support frame 2. The multi-directional drive assembly 3 is mounted on the processing table 1 to achieve precise multi-directional movement of the engraving head 3-10. The table cleaning assembly 4 is located on the upper end of the processing table 1 and is responsible for cleaning up debris and impurities generated during processing, ensuring a clean processing environment. The drive frame 3-1 is symmetrically arranged on opposite side walls of the support frame 2. A translation drive screw 3-2 is installed on its inner side wall. The output motor 3-3 is fixed to the side wall of the drive frame 3-1 to provide power to the translation drive screw 3-2. A translation frame 3-4 is meshed on the translation drive screw 3-2. When the output motor 3-3 starts, it drives the translation drive screw 3-2 to rotate, thereby causing the translation frame 3-4 to perform horizontal translational movement along the screw direction, realizing the horizontal movement of the engraving head 3-10 in the horizontal direction (X). The position adjustment of the axis is achieved by fixing a drive platform 3-5 on the upper end of the translation frame 3-4, installing a mounting frame 3-6 on the side wall of the drive platform 3-5, connecting the drive motor 3-7 on the mounting frame 3-6 to the longitudinal drive screw 3-8, and installing a sliding table 3-9 on the longitudinal drive screw 3-8. When the drive motor 3-7 is working, it drives the longitudinal drive screw 3-8 to rotate, causing the sliding table 3-9 to move up and down (Y-axis) along the longitudinal drive screw 3-8, thereby driving the engraving head 3-10 to move in the longitudinal direction, realizing the engraving operation of sensitive elements at different height positions.

[0041] A cleaning tank 4-1 is located on the upper surface of the processing table 1. A comb-shaped mounting platform 4-2 is installed inside the cleaning tank 4-1. During processing, the sensitive element is placed on the comb-shaped mounting platform 4-2 for engraving. Debris and impurities generated during processing fall into the cleaning tank 4-1 through the gaps in the comb-shaped mounting platform 4-2. A spray brush head 4-3 is installed on the side wall of the cleaning tank 4-1. The spray brush head 4-3 is aligned with the comb-shaped mounting platform 4-2. During or after processing, the spray brush head can be used to clean the sensitive element. 4-3 Spray cleaning fluid onto the comb-shaped mounting platform 4-2 to flush debris and impurities to the bottom of the cleaning tank 4-1. The side wall of the cleaning tank 4-1 is also provided with a drain port 4-4. The cleaning fluid and debris after flushing are discharged through the drain port 4-4. The comb-shaped mounting platform 4-2 is equipped with a residue filter screen 10. The residue filter screen 10 adopts an arc-shaped structure, which can effectively filter larger particles of debris and impurities, preventing them from entering the drain port 4-4 and causing blockage. It is also easy to clean and maintain.

[0042] The sensitive element is placed on the comb-shaped mounting platform 4-2 of the processing table 1. The position and angle of the engraving head 3-10 are adjusted according to the processing requirements. By controlling the output motor 3-3 and the translation drive screw 3-2, the translation frame 3-4 moves the engraving head 3-10 to a suitable horizontal position. By controlling the drive motor 3-7 and the longitudinal drive screw 3-8, the sliding table 3-9 moves the engraving head 3-10 to a suitable longitudinal height. If necessary, the height of the engraving head 3-10 can also be finely adjusted by the telescopic cylinder 6. The engraving head 3-10 is started and engraving operation is performed according to the preset program. During the engraving process, the multi-directional drive component 3 precisely controls the movement trajectory of the engraving head 3-10 according to the programmed instructions to realize the three-axis linkage engraving of the sensitive element.

[0043] like Figures 1-4 As shown, in this embodiment, a drive cover 3-11 is provided on the lower end face of the sliding stage 3-9, and a clamping frame 3-12 is provided on the side wall of the drive cover 3-11. The clamping frame 3-12 and the engraving machine head 3-10 are fixed and screwed together by bolts.

[0044] In some examples, the lower end of the sliding stage 3-9 is provided with an engraving head 3-10. Specifically, the lower end face of the sliding stage 3-9 is equipped with a drive cover 3-11, and the side wall of the drive cover 3-11 is fixedly connected to a clamping frame 3-12 by bolts. The engraving head 3-10 is mounted on the clamping frame 3-12.

[0045] For example, such as Figure 2 As shown, the side wall of the processing table 1 has a liquid collection tank insertion slot 4-5, which is located directly below the drain port 4-4.

[0046] In some examples, the side wall of the processing table 1 has a liquid collection tank insertion slot 4-5, which is located directly below the drain port 4-4. When in use, the liquid collection tank is inserted into the insertion slot to collect the cleaning fluid and debris discharged from the drain port 4-4, which is convenient for subsequent unified treatment and to keep the working environment clean.

[0047] For example, such as Figure 2 As shown, the sliding table 3-9 has a drive cavity 5 inside, and a telescopic cylinder 6 is installed inside the drive cavity 5. The telescopic end of the telescopic cylinder 6 is fixedly connected to the drive cover 3-11.

[0048] In some examples, the sliding stage 3-9 has a drive cavity 5 inside, and a telescopic cylinder 6 is installed in the drive cavity 5. The telescopic end of the telescopic cylinder 6 is fixedly connected to the drive cover 3-11. When it is necessary to make a fine adjustment to the height of the engraving head 3-10, it can be achieved by controlling the extension and retraction of the telescopic cylinder 6, which further improves the adaptability of the engraving machine to different processing needs.

[0049] For example, such as Figure 3 As shown, sliding limit plates 7 are provided on the opposite side walls of the sliding table 3-9, and sliding grooves 8 are provided on the upper surface of the sliding limit plates 7. Sliding wheels 9 are provided inside the sliding grooves 8, and the sliding wheels 9 are in contact with the translation frame 3-4.

[0050] In some examples, to ensure the stability and accuracy of the sliding stage 3-9 during movement, sliding limit plates 7 are provided on the opposite side walls of the sliding stage 3-9. A sliding groove 8 is provided on the upper end face of the sliding limit plate 7, and a sliding wheel 9 is installed in the sliding groove 8. The sliding wheel 9 is in close contact with the translation frame 3-4. When the sliding stage 3-9 moves, the sliding wheel 9 rolls along the translation frame 3-4, which plays a role in limiting and guiding, preventing the sliding stage 3-9 from deviating and improving the engraving accuracy.

[0051] For example, such as Figure 4 As shown, the residue filter screen 10 has an arc-shaped structure, and the residue filter screen 10 is installed inside the comb-shaped mounting platform 4-2.

[0052] In some examples, after the carving is completed, the table cleaning component 4 is activated, and the spray brush head 4-3 sprays cleaning fluid onto the comb-shaped mounting table 4-2, flushing the debris and impurities generated during the carving process into the cleaning tank 4-1. After being filtered by the residue filter screen 10, the cleaning fluid and fine impurities flow into the liquid collection tank through the drain port 4-4. After cleaning is completed, the liquid collection tank can be removed for cleaning, and the comb-shaped mounting table 4-2 and the residue filter screen 10 can also be cleaned to prepare for the next processing.

[0053] For example, such as Figure 2 As shown, a positioning frame 11 is provided on the side wall of the engraving machine head 3-10. The end of the positioning frame 11 is inserted into the interior of the drive cover 3-11. The positioning frame 11 and the interior of the drive cover 3-11 are fixed and screwed together by bolts.

[0054] In some examples, the side wall of the engraving head 3-10 is provided with a positioning frame 11. The end of the positioning frame 11 is inserted into the drive cover 3-11 and is fixedly screwed to the drive cover 3-11 by bolts. This double fixing structure ensures the stability and accuracy of the engraving head 3-10 during operation.

[0055] In operation, the output motor 3-3 serves as the power source, mounted on the side wall of the drive frame 3-1. Its output shaft is connected to the translation drive screw 3-2. When the motor is powered on, it drives the translation drive screw 3-2 to rotate. Since the translation frame 3-4 is threadedly fitted onto the translation drive screw 3-2, according to the principle of screw transmission, the rotational motion of the translation drive screw 3-2 is converted into the linear translational motion of the translation frame 3-4 along the screw axis. This allows for the horizontal (X-axis) position adjustment of the engraving head 3-10, providing a basis for engraving sensitive element areas at different horizontal positions. The drive motor 3-7 on the mounting frame 3-6 drives the longitudinal drive screw 3-8 to rotate. The sliding table 3-9 is also threadedly engaged with the longitudinal drive screw 3-8. Under the action of the drive motor 3-7, the rotation of the longitudinal drive screw 3-8 causes the sliding table 3-9 to move up and down along the screw (Y-axis). The shaft drives the engraving head 3-10 to move longitudinally, meeting the needs of engraving sensitive components at different heights and achieving vertical engraving depth control. The telescopic cylinder 6 in the drive cavity 5 inside the sliding table 3-9 is fixedly connected to the drive cover 3-11. When it is necessary to make a fine adjustment to the height of the engraving head 3-10, the telescopic cylinder 6 is controlled to extend and retract through the hydraulic system. The drive cover 3-11 drives the engraving head 3-10 to make a small-amplitude rise and fall, achieving precise fine adjustment of the engraving height to adapt to sensitive components of different thicknesses or different engraving process requirements.

[0056] The sliding limit plates 7, sliding grooves 8, and sliding wheels 9 on the opposite side walls of the sliding table 3-9 together constitute a limiting and guiding structure. The sliding wheels 9 are in close contact with the translation frame 3-4. During the movement of the sliding table 3-9, the sliding wheels 9 roll along the translation frame 3-4, limiting the movement direction of the sliding table 3-9 and preventing it from deviating or shaking. This ensures the stability and accuracy of the engraving head 3-10 and improves the engraving precision. The engraving machine is equipped with a CNC system. The operator uses programming software to write a machining program containing parameters such as engraving path, speed, and depth according to the design requirements of the sensitive element. The CNC system converts the machining program into electrical signals, which control the operation of the output motor 3-3, drive motor 3-7, and other actuators. During the engraving process, the CNC system monitors the position and speed of each axis in real time and compares them with the program settings. Through a closed-loop feedback control mechanism, the speed and direction of the motors are adjusted, thereby precisely controlling the engraving head 3-10 to move according to the preset trajectory, realizing three-axis linkage engraving of the sensitive element, and ensuring the accuracy and consistency of the engraving.

[0057] Debris Collection: During the engraving process, debris and impurities generated by the sensitive element fall naturally through the gaps in the comb-shaped mounting platform 4-2 and enter the cleaning tank 4-1. The design of the comb-shaped mounting platform 4-2 can both support the sensitive element and provide a falling channel for debris, facilitating subsequent cleaning. The spray head 4-3 is connected to an external cleaning fluid supply system. When the cleaning program is started, the cleaning fluid is sprayed out from the spray head 4-3 under pressure, with the spray direction aimed at the comb-shaped mounting platform 4-2. The impact force of the cleaning fluid washes the debris and impurities remaining on the comb-shaped mounting platform 4-2 into the cleaning tank. At the bottom of 4-1, the initial cleaning of the processing table 1 is completed. The arc-shaped residue filter 10 inside the comb-shaped placement table 4-2 filters the mixed liquid in the cleaning tank 4-1. Larger particles of debris and impurities are intercepted above the filter screen, while fine impurities and cleaning liquid enter the bottom of the cleaning tank 4-1 through the filter screen. The drain port 4-4 on the side wall of the cleaning tank 4-1 is connected to the liquid collection tank. Under the action of gravity, the filtered cleaning liquid and fine impurities flow into the liquid collection tank through the drain port 4-4, realizing the separation and collection of cleaning liquid and impurities, and keeping the processing table 1 clean.
