[0002] With the rapid development of electronic devices, circuit board manufacturing technology faces increasingly higher demands and challenges. While current production processes meet market demands to a certain extent, there is still much room for improvement. Some processes are not only time-consuming and energy-intensive, but also lead to material waste and low production efficiency. Therefore, it is necessary to gradually improve circuit board manufacturing technology to enhance production efficiency and reduce costs. In the production process of printed circuit boards, immersion gold plating is a key step, involving the deposition of a gold layer on the substrate surface to improve electroplating performance and soldering reliability.
[0003] When performing immersion gold plating, the circuit board needs to be suspended using Teflon wire. However, in the current technology, the two ends of the Teflon wire need to be tied to the equipment or directly hung on a hook. Both of these methods result in unstable connections, and the tying method also requires time to tie the two ends of the Teflon wire together, causing unnecessary trouble.
[0004] In view of this, the present invention proposes a loading and unloading device for immersion gold plating of circuit boards. Utility Model Content
[0005] This utility model proposes a loading and unloading device for immersion gold plating of circuit boards, which solves the problem that related technologies require tying both ends of the Teflon wire to the equipment or hanging it directly on a hook. Both methods result in unstable connections, and tying the two ends of the Teflon wire together takes time and causes unnecessary trouble.
[0006] The technical solution of this utility model is as follows: A loading and unloading device for immersion gold plating of circuit boards includes a column, a screw rotatably connected to the top of the column, a top plate threadedly connected to the surface of the screw, a connecting plate fixedly connected to the back of the column, a first servo motor whose output end is fixedly connected to one end of the connecting plate and fixedly connected to the screw, a vertical rod fixedly connected to the column and slidably connected inside the top plate, a second servo motor fixedly connected to the top of the top plate, a positive and negative lead screw rotatably connected to the top plate and fixedly connected to the output end of the second servo motor, and two sets of sliders slidably connected to the top plate and threadedly connected to the surface of the positive and negative lead screws.

Both sets of rotating plates have insertion holes on both sides. Both sets of sliders have rotating rods rotatably connected to their surfaces. The tail of each rotating rod is fixedly connected to a first bevel gear located inside the slider. Both sides of the first bevel gear are meshed with second bevel gears. The sides of both sets of second bevel gears are fixedly connected to transmission screws that are rotatably connected to the sliders. The surfaces of both sets of transmission screws are threadedly connected to fixing rods that are embedded in the insertion holes. The fixing rods are slidably connected to limiting plates that are fixedly connected to the sliders.
[0007] Preferably, a rotating screw is rotatably connected to the bottom of the top plate, a connecting plate is threaded onto the surface of the rotating screw, and a side plate that is slidably connected to the bottom of the top plate is fixedly connected to the top of the connecting plate.
[0008] Preferably, the rotating plate can be rotated to a state parallel to the bottom of the slider, and the top of the groove is closed by the slider.
[0009] Preferably, the groove is a straight line penetrating the rotating plate, and the adhesive layer completely covers the groove.
[0010] Preferably, the first bevel gear and the second bevel gear are perpendicular to each other, and the two sets of second bevel gears rotate synchronously in opposite directions through the first bevel gear.
[0011] Preferably, the two sets of fixing rods slide in opposite directions through two sets of transmission screws, and the fixing rods are tightly fitted with the insertion holes.
[0012] Preferably, the limiting plate is vertically disposed on the side of the slider.

[0014] The working principle and beneficial effects of this utility model are as follows:

Then, the rotating rod is rotated to control the first bevel gear to rotate, and the two sets of second bevel gears move accordingly, driving the two sets of transmission screws to rotate. Since the two sets of transmission screws rotate in opposite directions, the two sets of fixing rods can be controlled to slide along the limiting plate and embed into the insertion hole, thereby fixing the rotating plate and quickly fixing the Teflon wire and circuit board. The first servo motor is turned on to control the screw to rotate, so that the top plate descends along the vertical rod for immersion gold treatment.
[0016] 2. In this utility model, by setting a side plate, before the circuit board descends, the rotating screw can be rotated to control the connecting plate and the side plate to slide at the bottom of the top plate, thereby moving closer to the Teflon wire, thus limiting the Teflon wire and preventing the Teflon wire from shaking and causing the circuit board to shake.

Both sets of rotating plates 10 have grooves 11 inside, and adhesive layers 12 are fixedly connected inside the grooves 11. Both sides of the two sets of rotating plates 10 have insertion holes 13. Both sets of sliders 7 have rotating rods 14 rotatably connected to their surfaces. The tail of the rotating rod 14 is fixedly connected to a first bevel gear 15 located inside the slider 7. Both sides of the first bevel gear 15 are meshed with second bevel gears 16. The sides of the two sets of second bevel gears 16 are fixedly connected to transmission screws 17 rotatably connected to the sliders 7. The surfaces of the two sets of transmission screws 17 are threadedly connected to fixing rods 18 embedded in the insertion holes 13. The fixing rods 18 are slidably connected to a limiting plate 19 fixedly connected to the sliders 7.
[0026] In this embodiment, the rotating plate 10 can be rotated to a state parallel to the bottom of the slider 7, and the top of the groove 11 is closed by the slider 7. When the rotating plate 10 is parallel to the slider 7, the Teflon wire can be fixed in the groove 11.
[0027] In this embodiment, the groove 11 is a straight line that penetrates the rotating plate 10, and the adhesive layer 12 completely covers the groove 11. The groove 11 allows the Teflon wire to be locked inside itself.
[0028] In this embodiment, the first bevel gear 15 and the second bevel gear 16 are perpendicular to each other. The two sets of second bevel gears 16 rotate synchronously in opposite directions through the first bevel gear 15. The rotating rod 14 controls the rotation of the first bevel gear 15, and the two sets of second bevel gears 16 move accordingly, driving the two sets of transmission screws 17 to rotate.
[0029] In this embodiment, the two sets of fixing rods 18 slide in opposite directions through the two sets of transmission screws 17.

At this time, the two sets of sliders 7 will move relative to each other to adjust the gap between the two sets of sliders 7, thereby adapting to circuit boards of different sizes. Then, flip the rotating plate 10 downward to suspend the Teflon wire connecting the circuit board in the groove 11. Then, control the rotating plate 10 to fit tightly with the bottom of the sliders 7. Then, rotate the rotating rod 14 to control the first bevel gear 15 to rotate. The two sets of second bevel gears 16 move accordingly, driving the two sets of transmission lead screws 17 to rotate. The two sets of transmission screws 17 rotate in opposite directions, thus controlling the two sets of fixing rods 18 to slide along the limiting plate 19 and embed into the insertion hole 13, thereby fixing the rotating plate 10 and quickly fixing the Teflon wire and the circuit board. The first servo motor 5 is turned on to control the screw 2 to rotate, so that the top plate 3 descends along the vertical rod 6 for immersion gold treatment. Before the circuit board descends, the rotating screw 20 can be rotated to control the connecting plate 21 and the side plate 22 to slide at the bottom of the top plate 3, thereby moving closer to the Teflon wire to limit the Teflon wire and prevent the Teflon wire from shaking and causing the circuit board to shake.
