[0007] A baffle is fixedly connected to the front of the inner wall of the box. A groove is opened on the front of the inner wall of the baffle. A spring is fixedly connected to the bottom of the groove. A slider is fixedly connected to the top of the spring. A rubber pulley is rotatably connected to the back of the slider through a bearing.

[0017] The advantages of this application are:

[0018] I. In this application, after the circuit board slides from the slide plate onto the cooling belt body, the movement of the cooling belt body causes the circuit board to slide to the right.

The movable wheels of the limiting plate ensure that the circuit board does not deviate from the correct trajectory during movement, thus maintaining the stability and accuracy of the circuit board.

[0020] Third, in this application, when the movable plate is lifted, an alcohol roller applies alcohol to the outer wall of the rubber pulley, and further applies alcohol to the rolling circuit board.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Example 1, see Figures 1-5 This embodiment provides an intelligent PCB circuit board manufacturing post-cooling device, including: a housing 1; a cooling guide belt body 5, which is mounted on the front of the inner wall of the housing 1; a semiconductor cooler 8, which is mounted on the front of the inner wall of the housing 1; a slide plate 6, which is fixedly connected to the top of the housing 1; and a conveyor belt 7, which is fixedly connected to the bottom of the housing 1.

[0039] A baffle 21 is fixedly connected to the front of the inner wall of the housing 1. A groove 212 is opened on the front of the inner wall of the baffle 21. A spring 24 is fixedly connected to the bottom of the groove 212. A slider 22 is fixedly connected to the top of the spring 24. A rubber pulley 23 is rotatably connected to the back of the slider 22 through a bearing. A first rotating rod 28 is rotatably connected to the front of the inner wall of the baffle 21 through a bearing. A movable plate 211 is fixedly sleeved on the outer wall of the first rotating rod 28. A transmission assembly for driving the slider 22 and the movable plate 211 is assembled inside the housing 1. The circuit board enters the housing 1 under the action of the conveyor belt 7, slides along the slide plate 6 and contacts the cooling belt body 5. The cooling belt body 5 and the semiconductor cooler 8 work together to cool the circuit board from different directions. During the sliding process of the circuit board, the slider 22 slides in the groove 212 and compresses the spring 24. The rubber pulley 23 contacts the circuit board. Through the transmission component, the moving plate 211 and other components cooperate to make the rubber pulley 23 support and guide the circuit board. The elasticity of the spring 24 can buffer the sliding of the circuit board and prevent damage caused by the circuit board colliding with the baffle 21 and other components, thus achieving efficient cooling of the circuit board. At the same time, the structure of the spring 24 and the slider 22 plays a certain role in buffering and stabilizing the transmission process of the circuit board, improving the stability and reliability of the cooling process. The transmission assembly includes a first hydraulic chamber 25. Inside the first hydraulic chamber 25, a first hydraulic rod 26 is slidably connected to a piston at one end. The first hydraulic rod 26 is fixedly connected to the front of the slider 22. Inside the first hydraulic chamber 25, a second hydraulic rod 27 is slidably connected to a piston at one end. A toothed block is fixedly connected to the top of the second hydraulic rod 27. When the slider 22 slides in the slide groove 212, it drives the first hydraulic rod 26 to slide within the first hydraulic chamber 25. The hydraulic oil is squeezed within the first hydraulic chamber 25, pushing the second hydraulic rod 27 to slide upward within the first hydraulic chamber 25, thereby causing the toothed block to rise, preparing for subsequent meshing with the first spur gear 210. A first spur gear 210 is fixedly sleeved on the outer wall of the first rotating rod 28. The first spur gear 210 meshes with the toothed block. When the toothed block rises under the drive of the second hydraulic rod 27, it meshes with the first spur gear 210, causing the first spur gear 210 to rotate. The first spur gear 210 is fixedly sleeved on the outer wall of the first rotating rod 28, thereby driving the first rotating rod 28 to rotate. This causes the moving plate 211 and other components fixedly sleeved on the outer wall of the first rotating rod 28 to rotate and move accordingly, thereby adjusting and guiding the position of the circuit board. By setting the first spur gear 210 to mesh with the toothed block, the linear motion of the slider 22 is converted into the rotational motion of the first rotating rod 28, thereby driving the linkage of the moving plate 211 and other components, improving the automation level and transmission efficiency of the device, and making the collaborative work between the components smoother.A reduction pulley 29 is fixedly connected to the front of the first hydraulic chamber 25, and the reduction pulley 29 contacts the outer wall of the first hydraulic rod 26. Through holes are provided on the front and back of the housing 1. When the first hydraulic rod 26 slides in the first hydraulic chamber 25, its outer wall contacts the reduction pulley 29. The reduction pulley 29 provides a certain resistance to the movement of the first hydraulic rod 26, thereby slowing down the sliding speed of the first hydraulic rod 26, making the movement of the entire transmission device more stable, and preventing equipment failure caused by excessive movement of the hydraulic rod. By setting the reduction pulley 29 and making it contact the outer wall of the first hydraulic rod 26, and by providing through holes on the front and back of the housing 1, the movement of the hydraulic rod is slowed down and stabilized. At the same time, the design of the through holes facilitates the flow of hydraulic oil and the normal operation of the hydraulic system, ensuring the smoothness and reliability of the transmission process and extending the service life of the equipment.

[0040] In practical use, the aforementioned device has an external fan on the front of the housing 1 blowing air through the through-hole to circulate air inside the housing 1. The semiconductor cooler 8 is activated to cool the cooling belt body 5. The circuit board then slides from the sliding plate 6 onto the cooling belt body 5. Activating the cooling belt body 5 moves the circuit board to the right. As the circuit board moves to the right, it falls onto the moving plate 211 and then tilts to the right. This tilting causes the rubber pulley 23 to move to the bottom, which in turn moves the slider 22 to the bottom, compressing the spring. As spring 24 descends, slider 22 causes the first hydraulic rod 26 to descend. During the descent of the first hydraulic rod 26, the internal pressure of the first hydraulic chamber 25 decreases, causing the second hydraulic rod 27 and the toothed block to move to the right. The toothed block causes the first sprocket 210 to rotate counterclockwise, which in turn causes the first rotating rod 28 to rotate counterclockwise. The first rotating rod 28 then causes the moving plate 211 to rotate counterclockwise. Without the limiting effect of the moving plate 211, the circuit board slides down the second cooling belt body 5 via the rubber pulley 23, simultaneously flipping the circuit board.

[0041] Example 2, see Figures 6-7Based on Embodiment 1, the housing 1 is equipped with a calibration device 3 for correcting the position of the circuit board. After the circuit board enters the housing 1, the calibration device 3 fine-tunes and calibrates the circuit board according to its actual position and shape through its internal hydraulic system and mechanical structure, so that the circuit board can accurately contact the cooling components such as the cooling belt body 5, ensuring the consistency of the cooling effect. By assembling the calibration device 3, the precise calibration of the PCB circuit board position is achieved, ensuring that the circuit board always maintains the correct posture and position during the cooling process, improving the uniformity and efficiency of cooling, and avoiding problems such as poor cooling effect or equipment damage caused by the circuit board position deviation. The calibration device 3 includes a second hydraulic chamber 31. Inside the second hydraulic chamber 31, a piston is slidably connected to a third hydraulic rod 32 at one end. A fixed rod 33 is fixedly connected to the back of the third hydraulic rod 32. The fixed rod 33 is fixedly connected to the bottom of the moving plate 211. When the moving plate 211 rotates and moves under the drive of the first rotating rod 28, the fixed rod 33 moves accordingly, causing the piston of the third hydraulic rod 32 to slide inside the second hydraulic chamber 31. Hydraulic oil flows inside the second hydraulic chamber 31, thereby adjusting the position and orientation of the calibration device 3 to adapt to the calibration requirements of the circuit board. By setting up the structure composed of the second hydraulic chamber 31, the third hydraulic rod 32, and the fixed rod 33, the linkage between the calibration device 3 and the moving plate 211 is realized, enabling the calibration device 3 to automatically adjust according to the position change of the moving plate 211, improving the flexibility and accuracy of calibration, and better adapting to the calibration needs of circuit boards of different sizes and shapes. A third hydraulic chamber 34 is fixedly connected to the front of the movable plate 211. A fourth hydraulic rod 35 is slidably connected to one end of the piston inside the third hydraulic chamber 34. An elastic telescopic rod 36 is fixedly connected to the back of the fourth hydraulic rod 35. A limit plate 37 is fixedly connected to the back of the elastic telescopic rod 36. A movable wheel 38 is hinged to the inner wall of the limit plate 37. When the third hydraulic rod 32 slides within the second hydraulic chamber 31, hydraulic oil is transmitted to the third hydraulic chamber 34 through the connecting hose 39, pushing the fourth hydraulic rod 35 to slide within the third hydraulic chamber 34, causing the elastic telescopic rod 36 and the limit plate 37 to move. The movable wheel 38 on the inner wall of the limit plate 37 contacts the circuit board, facilitating electrical contact. The circuit board is limited and adjusted. The elasticity of the elastic telescopic rod 36 allows the moving wheel 38 to make certain adaptive adjustments according to the surface shape of the circuit board, achieving precise calibration. The structure composed of the third hydraulic chamber 34, the fourth hydraulic rod 35, the elastic telescopic rod 36, the limiting plate 37, the moving wheel 38, and the connecting hose 39 further enhances the adjustment capability and stability of the calibration device 3, enabling the calibration device 3 to limit and calibrate the circuit board in multiple directions. At the same time, the cooperation between the elastic telescopic rod 36 and the moving wheel 38 improves the flexibility and adaptability of the calibration process, ensuring that the circuit board is not damaged by collision or squeezing during the calibration process.

[0042] In actual use, the moving plate 211 descends, which in turn drives the fixed rod 33 to descend. The fixed rod 33 drives the third hydraulic rod 32 to descend. As the third hydraulic rod 32 descends, the internal pressure of the second hydraulic chamber 31, the third hydraulic chamber 34, and the connecting hose 39 increases, which drives the two fourth hydraulic rods 35 to move towards each other. The fourth hydraulic rods 35 drive the elastic telescopic rod 36 and the limiting plate 37 to limit the sliding trajectory of the circuit board. The circuit board moves through the moving wheel 38 of the limiting plate 37.

[0043] Example 3, see Figure 8Based on Embodiment 1, the housing 1 is equipped with an alcohol-applying device 4 for applying alcohol to the rubber pulley 23 and the cooling belt body 5. During equipment operation, the alcohol-applying device 4, through its internal rotating structure and the cooperation of the alcohol roller 43, evenly applies alcohol to the surfaces of the rubber pulley 23 and the cooling belt body 5. When the circuit board comes into contact with these components, the alcohol effectively cleans the surfaces, ensuring smooth cooling and transmission processes. This achieves the function of applying alcohol to the rubber pulley 23 and the cooling belt body 5. The volatility of alcohol provides a dual function of cleaning and cooling, effectively removing dust, stains, and other impurities from the surfaces of the rubber pulley 23 and the cooling belt body 5, preventing impurities from affecting the contact between the circuit board and the cooling components. Simultaneously, it also cleans the circuit board, improving product quality and performance. The coating device 4 includes a second rotating rod 41, which is rotatably connected to the front of the inner wall of the baffle 21 via a bearing. A connecting frame 42 is fixedly sleeved on the outer wall of the second rotating rod 41, and an alcohol roller 43 is fixedly connected to the front of the inner wall of the connecting frame 42. When the device is running, the second rotating rod 41 rotates under the action of external force, driving the connecting frame 42 and the alcohol roller 43 to rotate together. The surface of the alcohol roller 43 is soaked in alcohol. During the rotation, the alcohol is evenly coated on the surface of the rubber pulley 23 and the cooling belt body 5, achieving cleaning and cooling treatment of their surfaces. By setting up the coating structure composed of the second rotating rod 41, the connecting frame 42 and the alcohol roller 43, the uniform coating of alcohol is achieved, ensuring that the surface of the rubber pulley 23 and the cooling belt body 5 can be fully covered with alcohol, improving the cleaning effect. At the same time, the rotation mode of the alcohol roller 43 also makes the coating process more efficient and stable, and will not cause poor local cleaning effect due to uneven coating. A second sprocket 44 is fixedly sleeved on the outer wall of the first rotating rod 28, and a third sprocket 45 is fixedly connected to the outer wall of the second rotating rod 41. The second sprocket 44 and the third sprocket 45 mesh with each other. Alcohol is adhered to the outer wall of the alcohol roller 43. When the first rotating rod 28 rotates under the drive of the transmission component, the second sprocket 44 fixedly sleeved on its outer wall rotates. At the same time, the second sprocket 44 on the outer wall of the first rotating rod 28 rotates accordingly and meshes with the third sprocket 45, driving the third sprocket 45 to rotate. The third sprocket 45 is fixedly connected to the outer wall of the second rotating rod 41, thereby driving the second rotating rod 41 to rotate. This allows the coating device 4 to work synchronously, realizing the application of alcohol to the rubber pulley 23 and the cooling belt body 5. By setting the second sprocket 44 and the third sprocket 45 to mesh with each other, the linkage between the first rotating rod 28 and the second rotating rod 41 is realized, making the rotation of the coating device 4 and the movement of the transmission component coordinated. This ensures that the coating process and the circuit board cooling process are carried out synchronously, improving the overall operating efficiency and coordination of the equipment, and ensuring that the relevant components can be cleaned in a timely manner while cooling.

[0044] In practical use, when the moving plate 211 is tilted up, the alcohol roller 43 applies alcohol to the outer wall of the rubber pulley 23, and the rubber pulley 23 applies alcohol to the rolling circuit board. When the moving plate 211 is flipped, it drives the first rotating rod 28 to rotate, the first rotating rod 28 drives the second sprocket 44 to rotate, the second sprocket 44 drives the third sprocket 45 to rotate, the third sprocket 45 drives the second rotating rod 41 to rotate, and the second rotating rod 41 drives the connecting frame 42 and the alcohol roller 43 to flip. The alcohol roller 43 applies alcohol to the outer wall of the cooling belt body 5.
