Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a rust prevention device for a drilling target spindle and a drilling target machine. Background Technology

[0002] During the manufacturing process of circuit boards, drilling machines are used to drill holes in the boards. The drilling spindle of these machines is typically driven by compressed air. Because dryers cannot completely filter out moisture from the compressed air, moisture enters the drilling spindle. When the spindle rotates at high speed, the heat generated easily reacts with this moisture, causing rust to form. The accumulation of rust powder leads to jamming in the spindle's transmission mechanism, affecting its rotational speed, reducing drilling efficiency and quality, and shortening the spindle's lifespan. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rust prevention device for the drill target spindle and a drill target machine, which can prevent direct contact between the transmission components of the drill target spindle and moisture, and coat the transmission components of the drill target spindle with an oil film, thereby solving the problem of frequent rusting of the drill target spindle and extending its service life.

[0004] On one hand, this utility model embodiment provides a rust prevention device for a drill target spindle, installed on the pipeline between the drill target spindle and an external air source, including an oil mist generator, a solenoid valve, an air compressor filter, and a controller.

[0026] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1 and Figure 2This embodiment discloses a rust prevention device for a drill target spindle, installed on the pipeline between the drill target spindle 100 and an external air source. The device includes an oil mist generator 200, a solenoid valve 300, an air compressor filter 400, and a controller 500. The oil mist generator 200 is installed below the drill target spindle 100, and its output end is connected to the air compressor inlet of the drill target spindle 100 via a solenoid valve 300 to deliver oil mist into the drill target spindle 100. The air compressor filter 400 is installed on one side of the oil mist generator 200 and is connected to the oil mist generator 200 via a first pipeline 410. The controller 500 is electrically connected to the oil mist generator 200, the solenoid valve 300, and the air compressor filter 400.

[0028] Liquid lubricating oil is added to the oil mist generator 200 to generate a mist-like oil droplets containing lubricating oil. The inlet of the solenoid valve 300 is connected to the oil mist generator 200, and the outlet of the solenoid valve 300 is connected to the drill target spindle 100. The solenoid valve 300 controls the on / off state between the oil mist generator 200 and the drill target spindle 100 as needed, precisely controlling the fluid flow path and achieving effective control of the oil mist flow direction and flow rate. The air compressor filter 400 is connected to an external air source to provide stable pressurized air and filter impurities, ensuring that the air entering the oil mist generator 200 meets the cleanliness requirements and improving the reliability of the lubrication system. The clean air generated by the air compressor filter 400 is delivered to the oil mist generator 200 through the first pipeline 410 to help it generate a uniform oil mist. After receiving the operation signal, the controller 500 controls the solenoid valve 300 to open or close, adjusting the state of the fluid channel to allow the oil mist to pass smoothly or cut off, effectively controlling the oil mist flow direction and flow rate. It can block the direct contact between the transmission components of the drill spindle 100 and water vapor, and coat the transmission components of the drill spindle 100 with an oil film; thus achieving continuous lubrication of the drill spindle 100, preventing water vapor corrosion, and improving the working efficiency and service life of the drill spindle 100.

[0029] Please see Figure 2 The system comprises two drill spindles 100, each connected to a first air compressor pipe 110 and a second air compressor pipe 120. Each drill spindle 100 receives compressed air through these pipes, providing necessary cooling and lubrication to maintain stability during high-speed operation and extend its service life, ensuring efficient and accurate drilling. The continuous cooling and lubrication of the drill spindles through the compressed air pipes further stabilizes them at high speeds, reducing wear and effectively improving drilling efficiency. The two drill spindles allow for simultaneous positioning and drilling of two drill targets, enabling precise control, meeting the needs of batch processing, and improving overall work efficiency.

[0030] Please see Figure 2 The solenoid valve 300 is connected to the first compressed air pipe 110 and the second compressed air pipe 120 via a three-way air pipe connector 310. The solenoid valve 300 selectively connects or disconnects the first compressed air pipe 110 and the second compressed air pipe 120 according to a control signal. The three-way air pipe connector 310 is used to connect the solenoid valve 300, the first compressed air pipe 110, and the second compressed air pipe 120, realizing the connection or disconnection of the air circuit. By energizing the solenoid valve 300, the on / off state between the oil mist generator 200 and the drill target spindle 100 can be flexibly controlled, achieving precise control of the compressed air flow.

[0031] Please see Figure 2 The solenoid valve 300 is a two-position, three-way solenoid valve. The two positions of the two-position, three-way solenoid valve control the fluid flow path. When the solenoid valve 300 receives an electrical signal and is energized, the internal iron core is attracted and moved, changing the valve position and thus switching the fluid direction. When de-energized, the spring returns the valve core to its initial position, ensuring the valve can accurately switch the fluid flow direction. The solenoid valve 300 can control the on / off state between the oil mist generator 200 and the drill spindle 100 as needed, precisely controlling the fluid flow path and achieving effective control of the oil mist flow direction and flow rate.

[0032] Please see Figure 2 The oil mist generator 200 is connected to the solenoid valve 300 through the second pipeline 420. When the drill spindle 100 is started or stopped, oil and gas enter the solenoid valve 300 through the second pipeline 420, which lubricates the valve core of the solenoid valve 300.

[0033] Please see Figure 2 The oil mist generator 200 is equipped with a regulating valve 210, which is electrically connected to the controller 500. The regulating valve 210 is used to regulate the oil dripping speed. By precisely controlling the oil flow rate, the regulating valve 210 achieves fine control over the amount of oil mist generated, thereby ensuring that the amount of oil mist sprayed is within the required range and avoiding excessive or insufficient oil mist from affecting the normal operation and efficiency of the drill bit. By adjusting the regulating valve 210, the oil can be dripped at an appropriate speed, forming fine and uniform oil mist particles after atomization. These fine oil mist particles can more effectively contact the surface of the transmission components of the drill bit spindle 100, providing uniform lubrication and cooling effects, thereby improving drilling quality and efficiency.

[0034] Please see Figure 2 The air compressor filter 400 is equipped with a main air source inlet 430. The air compressor filter 400 is connected to an external air source through the main air source inlet 430, thereby providing stable pressurized air and filtering out impurities to ensure that the air entering the oil mist generator 200 meets the cleanliness requirements and improves the reliability of the lubrication module.

[0035] Please see Figure 2 The first pipeline 410 is provided with an air source port 440. The function of the air source port 440 is to connect to an external air source and provide the necessary driving air pressure; the air source port 440 provides air to other pneumatic components of the drilling machine (such as cylinders).

[0036] Please see Figure 1 and Figure 2 A drill target pressure foot 130 is provided above the drill target spindle 100. The drill target pressure foot 130 can press the circuit board placed on the processing table. When drilling is required on the circuit board, the circuit board is first placed on the processing table and pressed and fixed by the drill target pressure foot 130. Then, the drill target spindle 100 drives the drill bit to move up and down through the internal drive device to achieve precise drilling.

[0037] This embodiment also discloses a target drilling machine, including the aforementioned anti-rust device for the target spindle. The target drilling machine is also equipped with a display module 510, which is used to display and set target drilling parameters to improve drilling accuracy.

[0038] In use, liquid lubricating oil is added to the oil mist generator 200. The oil dripping frequency of the oil mist generator 200 is adjusted via the regulating valve 210 according to the operating time of the drill spindle 100. When the drill spindle 100 is started and stopped, oil vapor enters the solenoid valve 300, lubricating the valve core. The oil vapor then enters the air pressure inlet of the drill spindle 100 through the solenoid valve 300 and reaches the transmission components inside the drill spindle 100. With repeated operation of the drill spindle 100, the oil vapor evenly covers the transmission components inside the drill spindle 100. After a period of time, all transmission components inside the drill spindle 100 are evenly covered with an oil film. This oil film lubricates the transmission components inside the drill spindle 100, significantly reducing the frequent rusting of the drill spindle 100 and extending its service life to a certain extent. During operation, by adjusting the oil dripping frequency of the oil mist generator 200, the dripping frequency is balanced with the amount of oil consumed by the high-speed rotation and heat generation of the drill target spindle 100. This prevents excess oil vapor from accumulating and causing oil accumulation on the drill target spindle 100. This solves the problem of frequent rusting of the drill target spindle 100, extends its service life, and improves the drilling efficiency and quality of the drill target machine.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
