[0002] In the current era of rapid development in the electronics manufacturing industry, PCB boards serve as the "nerve center" of electronic devices. In the entire process of PCB board processing, the flipping process is a key link connecting the processing of different sides. Its efficiency and precision directly determine the quality stability of subsequent processes, making it one of the core nodes affecting overall production efficiency. Traditional PCB flipping equipment has many shortcomings in practical applications and is difficult to adapt to the needs of modern production: In the clamping and fixing process, manual knob clamping is not only labor-intensive and inefficient, but also suffers from inconsistent clamping force due to reliance on human experience, easily resulting in problems such as PCBs sliding due to excessive looseness or damaging the boards due to excessive tightness; while pneumatic clamping achieves semi-automation, it is greatly affected by fluctuations in air source pressure, resulting in unstable clamping force and easy air leakage and attenuation, requiring frequent maintenance; in the conveying process, manual loading and unloading are often required, which is not only inefficient, but also prone to PCB positioning misalignment due to human operation errors. Therefore, the above problems need to be solved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a PCB board flipping machine, comprising a body 1, with four telescopic support columns 2 fixedly connected to the four corners of the bottom of the body 1. The telescopic support columns 2 facilitate adaptation to different ground flatness and ensure that the body 1 remains horizontal. Pins for fixing are inserted into the telescopic support columns 2. Four rollers are rotatably mounted on the bottom of the body 1, enabling the flipping machine to move flexibly. A feed inlet is opened at the top of the body 1, with a cover plate hinged to the top of the feed inlet. A motor is installed on the outer wall of the body 1, and a flipping component is installed inside the body 1. A first belt conveyor 6 is provided on one side of the top of the flipping component, facilitating automated PCB board feeding, ensuring continuous and stable feeding, and reducing errors and labor intensity from manual feeding. A second belt conveyor 3 is provided on the other side of the bottom of the flipping component, facilitating automated transport of the flipped PCB board, improving production continuity, and reducing inefficiency and risk of board damage caused by manual handling.

[0015] In this invention, the flipping component includes symmetrically mounted rotating bearings on the inner walls of both sides of the machine body 1. A rotating shaft 7 is rotatably mounted on each of the two rotating bearings. One end of the rotating shaft 7 extends out of the outer wall of the machine body 1 and is coaxially fixed to the motor. A mounting sleeve is fitted onto the rotating shaft 7. Four placement plates 4 are axially arrayed around the mounting sleeve. Placement slots for placing PCB boards are provided on the placement plates 4. The flipping component facilitates continuous flipping operations, improving equipment processing efficiency. An electric push cylinder 8 is mounted on the side wall of the placement slot. A clamping plate 9 is fixedly connected to the output end of the electric push cylinder 8. A buffer spring 10 is mounted on one side of the clamping plate 9. One end of the buffer spring 10 movably abuts against the side wall of the PCB board. The electric push cylinder 8 provides a stable clamping force, ensuring that the PCB board does not loosen or shift during the flipping process, and the clamping force can be precisely controlled by the electric push cylinder 8. Multiple vent holes are equidistantly opened on the mounting sleeve. A connecting groove is opened at one end of the mounting sleeve. A gas flow block 12 is rotatably connected within the connecting groove. A connecting rod is fixedly connected to the side wall of one end of the gas flow block 12. The machine body 1 has a pipe with a connecting pipe fixed to it. An air blowing plate 13 is used to blow dust during the PCB board flipping process. The air blowing plate 13 has three air outlets on one side and a connecting column fixed to the other side. The other end of the connecting column is welded to the inner wall of the machine body 1. The air blowing plate 13 facilitates the removal of surface dust and impurities during the PCB board flipping process, reducing the impact of dust on subsequent processing steps and improving the cleanliness of the PCB board. A mounting slot is provided on one side of the machine body 1. A dust collection box 5 is fixed to the mounting slot by bolts. A suction pump is installed in the dust collection box 5. A dust collection plate 11 is fixed inside the dust collection box 5. A suction pipe for collecting dust blown off the PCB board is fixed to one side of the dust collection box 5. The dust collection box 5 facilitates the effective collection of dust generated during operation, keeping the inside of the equipment and the production environment clean and reducing dust pollution and damage to the PCB board and equipment. An observation window is fixed to the top of the cover plate. The observation window is made of transparent acrylic material and has a sealing strip on the edge. A handle for easy opening is fixed to the other side of the cover plate.

[0016] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power supply. Then, according to the requirements of the work site, adjust the height of the telescopic support column 2 at the bottom of the machine body 1 and fix it with the pin to keep the machine body 1 horizontal. If the machine needs to be moved, shorten the support column 2 so that the bottom roller contacts the ground, push the machine body 1 to the designated position, and then adjust the support column 2 again to fix it. Open the feed port cover and check whether each component is operating normally, ensuring that the dust collection box 5 is installed in place and the air source connection is unobstructed. Next, the PCB board to be processed is automatically transported by the first belt conveyor 6 to the flipping component inside the machine body 1. The first belt conveyor 6 accurately pushes the PCB board into the placement slot of one of the placement plates 4 on the periphery of the mounting sleeve, completing the loading action. At this time, the electric push cylinder 8 on the side wall of the placement slot starts, driving the clamping plate 9 to move towards the PCB board. The buffer spring 10 flexibly clamps and fixes the PCB board. The buffer spring 10 can automatically adjust the compression amount according to the thickness of the board to avoid rigid clamping damaging the PCB board. Then, the motor starts and the air supply is connected to the power supply. The output shaft drives the rotating shaft 7 to rotate around the rotating bearings on both sides of the machine body 1. The rotating shaft 7 then drives the mounting sleeve and four placement plates 4 to rotate synchronously. When the placement plate 4 carrying the PCB board rotates to a preset angle with the mounting sleeve, the motor stops precisely, completing the PCB board flipping action. At the same time, the gas flow block 12 continuously supplies airflow to the air blowing plate 13 through the connecting pipe. The three air outlets of the air blowing plate 13 spray airflow onto the surface of the flipped PCB board, blowing off the dust and impurities attached to the board. The suction pump in the dust collection box 5 starts and sucks the blown-off dust into the dust collection box 5 through the suction pipe. The dust is filtered and adsorbed by the dust collection plate 11, realizing simultaneous cleaning and dust collection, avoiding secondary dust pollution. Finally, after the flipping is completed, the electric push cylinder 8 corresponding to the position of the placement plate 4 moves in the opposite direction, driving the clamping plate 9 away from the PCB board, releasing the PCB board, and allowing it to fall smoothly into the second belt conveyor 3 below. The second belt conveyor 3 transports the flipped and cleaned PCB board to the next processing stage, completing the entire flipping process. This concludes the use of a PCB board processing flipping machine.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
