[0002] During the production of PCB substrates, printing a green solder mask layer on the PCB substrate can provide protection and insulation.
[0003] However, in the actual printing process, due to poor fluidity of the green ink or excessively fast printing speed, air bubbles may inevitably appear in the dense lines of the green ink, which will affect the product quality of the PCB substrate printing. Existing green ink printing equipment usually does not have the function of de-bubbling, and further processing is required, which is relatively cumbersome.
[0004] To address these issues, an improved green oil extraction device based on PCB manufacturing is proposed. Utility Model Content

The other end of the telescopic hose is detachably connected to the pump head. The pump head has interconnected pump holes and pump grooves on its end and sidewall. A sealing adjustment component is fitted on the pump head to adjust the opening width of the pump groove.
[0007] Furthermore, the sealing adjustment component includes a sleeve and a push-pull part. The sleeve is movably fitted onto the liquid extraction head for sealing adjustment of the liquid extraction tank, and the outer wall of the sleeve is connected to the push-pull part.
[0008] Furthermore, the bubble extraction mechanism also includes an electric micro push rod, an adjusting seat, a guide sleeve, a connecting shaft, and a micro motor. The electric micro push rod is installed on the mounting seat near the telescopic hose. The telescopic shaft end of the electric micro push rod is connected to the adjusting seat. The guide sleeve is rotatably connected to the adjusting seat via the connecting shaft. The adjusting seat is equipped with a micro motor connected to the connecting shaft, which is used to drive the guide sleeve to rotate and adjust the angle.
[0009] Furthermore, it also includes a connecting arm and a smart recognition camera. The upper part of the mounting base is equipped with a smart recognition camera for recognizing the green solder mask status on the PCB substrate via the connecting arm.
[0010] Furthermore, it also includes a telescopic rod, which connects the mounting base and the adjusting base.
[0011] Furthermore, it also includes a protective cover, which is provided on the mounting base to enclose the bubble extraction mechanism.
[0012] The beneficial effects of this utility model are as follows: by integrating the bubble extraction mechanism into the green ink printing machine, it is possible to adjust the angle and position of the extraction head in multiple dimensions, and also to adjust the opening size of the extraction tank by pushing and pulling the adjusting sleeve. This is beneficial for flexibly adapting to the width of different green ink printing lines, thereby improving the printing quality of the green ink and ensuring the continuity and reliability of the PCB circuit.

Detailed Implementation
[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0020] Example: This utility model provides a green oil degassing device for PCB production, such as... Figures 1 to 5 The system includes an organic platform 1, a printing tank 10, a green ink printing machine 2, a moving mechanism 4, a defoaming mechanism, and sealing adjustment components. The printing tank 10 and the green ink printing machine 2 are mounted on top of the platform 1. The main body of the green ink printing machine 2 is made of lightweight, high-strength metal material, which helps ensure the stability and durability of the equipment. The overall design is modular, facilitating maintenance and component replacement. The printing tank 10 also has a defoaming mechanism installed within the moving mechanism 4 for defoaming the green ink printed on the PCB substrate c. The defoaming mechanism includes a mounting base 5, a liquid pump 50, a collection cup 51, a telescopic hose 52, and a liquid suction head 6. The liquid pump 50 is connected to the moving mechanism 4 via the mounting base 5. The liquid pump 50 is a high-efficiency... The low-noise design ensures effective foaming without affecting the production environment. A collection cup 51 is detachably connected to the outlet of the pump 50 to collect a portion of the extracted green oil. A flexible hose 52 is fitted onto the inlet of the pump 50 and is made of corrosion-resistant and high-temperature-resistant material. The other end of the flexible hose 52 is detachably connected to a suction head 6, which has interconnected suction holes 60 and suction grooves 61 on its end and sidewall. The suction head 6 is adjustable, allowing for flexible adjustment based on the width of the green oil printing lines, thus ensuring accurate foaming positioning. A sealing adjustment element is fitted onto the suction head 6 to adjust the opening size of the suction groove 61.
[0021] Furthermore, such as Figures 3 to 5The sealing adjustment component includes a sleeve 7 and a push-pull part 70. The sleeve 7 is movably sleeved on the liquid extraction head and is used to adjust the sealing of the liquid extraction tank 61. The outer wall of the sleeve 7 is connected to the push-pull part 70, which is used to fine adjust the size of the opening of the liquid extraction tank 61, thereby facilitating the application of green oil layer lines of different widths.
[0022] Furthermore, such as Figures 3 to 5 The aeration mechanism also includes an electric micro push rod 53, an adjusting seat 54, a guide sleeve 8, a connecting shaft 80, and a micro motor 81. The electric micro push rod 53 is installed on the mounting seat 5 near the telescopic hose 52. The telescopic shaft end of the electric micro push rod 53 is connected to the adjusting seat 54. The guide sleeve 8 is rotatably connected to the adjusting seat 54 through the connecting shaft 80. The adjusting seat 54 is equipped with a micro motor 81 connected to the connecting shaft 80, which is used to drive the guide sleeve 8 to rotate and adjust the angle so as to control the tilt angle of the aeration head 6 and improve its applicability.
[0023] Furthermore, such as Figure 3 It also includes a connecting arm 9 and a smart recognition camera 90. The upper part of the mounting base 5 is equipped with a smart recognition camera 90 for recognizing the state of the green oil on the PCB substrate c via the connecting arm 9, which helps to improve the degassing quality of bubbles on the green oil layer.
[0024] Furthermore, such as Figure 3 It also includes a telescopic rod 55, which connects the mounting base 5 and the adjusting base 54 to provide stable guidance for the adjusting base 54, guide sleeve 8, connecting shaft 80 and micro motor 81 to move up and down.
[0025] Furthermore, such as Figure 1 It also includes a protective cover 11. The mounting base 5 is equipped with a protective cover 11 for wrapping the bubble extraction mechanism, which can effectively prevent operators from accidentally touching it and damage the equipment.
[0026] In addition, such as Figure 1 and Figure 2 The top of the green oil printing machine 2 is also equipped with a connection port 3 with a sealing structure, which helps to prevent green oil leakage and pollution; the front of the upper part of the machine base 1 is also equipped with a PLC control panel a and an emergency stop knob b. The emergency stop knob b helps to ensure that the equipment can be stopped quickly in an emergency, ensuring safe operation; and a PLC (Programmable Logic Controller) is used as the control core to achieve precise control of components such as the liquid pump 50 and the liquid head 6. It is equipped with a touch screen operation interface, which makes it convenient for operators to set parameters and monitor the equipment operation status.
[0027] Green ink is evenly printed onto the PCB substrate c using a green ink printing machine 2 to form the required circuit pattern. When air bubbles appear at the dense lines of the green ink layer after printing, the de-bubbling pump is started to extract the air from the de-bubbling tube, creating a negative pressure suction force. The horizontal movement position of the pump 50 is controlled by the moving mechanism 4. The position of the adjusting seat 54 and the suction head 6 is adjusted by the electric micro push rod 53. The longitudinal rotation and swing of the connecting shaft 80 and the guide sleeve 8 are controlled by the micro motor 81, thereby adjusting the tilt angle of the suction head 6. The suction head 6 is moved to the green ink layer. At the location of densely packed solder mask lines, air bubbles in the solder mask are extracted using negative pressure, thus ensuring the continuity and reliability of the solder mask lines. During the extraction process, an intelligent recognition camera 90 monitors the air bubbles in the solder mask layer of the PCB substrate c in real time and adjusts the operation of the extraction pump according to set parameters, thereby ensuring the quality of solder mask extraction. In addition, by pushing and pulling the adjusting sleeve 7 to cover the straight extraction tank 61, the opening size of the extraction tank 61 can be easily controlled by covering different areas, which is beneficial for adapting to different widths of solder mask printed lines and making it more convenient to use.
[0028] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
