[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-2An immersion nickel-gold system includes a fixed base 1, an immersion tank assembly 2, a traveling device 3, a connecting crossbar 4, a hanging basket 5, an adjusting device 6, a swinging device 7, a vibration device 8, and an exhaust device 9. The fixed base 1 is used to support the entire production line and may include a fixed frame and a transparent cover. The transparent cover allows the fixed base 1 to be in a relatively sealed state, reducing the impact on the outside world during processing, while facilitating observation of the working status inside the production line. The fixed base 1 is equipped with the immersion tank assembly 2 and the traveling device 3. The immersion tank assembly 2 includes multiple immersion tanks 21 for holding different processing solutions, such as immersion nickel-gold solution, pure water, and tap water, which can realize different treatments of circuit boards.

[0019] The traveling device 3 is located above the immersion tank group 2. The traveling device 3 has a movable motor, a movable slide rail, and other mechanisms. The movable slide rail is equipped with a lifting component 31, which may include a lifting motor, a lifting slide rail, and other mechanisms. This is existing technology and will not be described in detail here. The bottom of the lifting component 31 is equipped with a connecting crossbar 4. A hanging basket 5 is detachably connected to the connecting crossbar 4. The hanging basket 5 can be loaded with circuit boards to be processed. The traveling device 3 can drive the connecting crossbar 4 and the hanging basket 5 to move above the immersion tank group 2. The lifting component 31 can drive the connecting crossbar 4 and the hanging basket 5 to rise and fall, so that the hanging basket 5 can be inserted and matched with the immersion tank group 2. By placing the hanging basket 5 with the circuit boards in different immersion tanks, different processing of the circuit boards can be achieved.

[0020] An adjustment device 6 is provided between the connecting crossbar 4 and the lifting assembly 31. The tilt angle of the hanging basket 5 can be adjusted by the adjustment device 6, thereby accelerating the discharge of liquid on the hanging basket 5 after the hanging basket 5 is separated from the immersion tank group 2, thus avoiding the reduction of the residual reaction liquid on the hanging basket 5, saving resources and reducing costs.

[0021] In some embodiments, the adjusting device 6 includes an adjusting motor 61, which is located on one side of the lifting assembly 31. A mounting plate can be provided on one side of the lifting assembly 31 for fixing the adjusting motor 61. The output shaft of the adjusting motor 61 is provided with a drive gear 62, and the output shaft of the adjusting motor 61 can be rotatably connected to the side wall of the lifting assembly 31, which can improve the stability of the output shaft of the adjusting motor 61 when rotating. A driven gear 63 is sleeved on the connecting crossbar 4, and the drive gear 62 meshes with the driven gear 63. By adjusting the rotation of the motor 61, the driven gear 63 meshing with the drive gear 62 can drive the connecting crossbar 4 to rotate, so that the basket can form a certain angle when tilted, thereby achieving the tilting of the basket 5 and accelerating the outflow of liquid from the basket 5.

[0022] In some embodiments, the connecting crossbar 4 includes a rotating sleeve 41, which is located at the bottom of the lifting assembly 31 and can be welded and fixed by bolt assembly. A rotating rod 42 is provided through the rotating sleeve 41, allowing the rotating rod 42 to rotate on the rotating sleeve 41. A driven gear 63 is sleeved on the rotating rod 42 and can be welded and fixed. Connecting blocks 43 are symmetrically provided at both ends of the rotating rod 42. The size of the connecting blocks 43 can be larger than the diameter of the rotating rod 42, thereby preventing the rotating rod 42 from separating from the rotating sleeve 41 when the rotating rod 42 rotates. A connecting groove 44 is provided in the middle of the connecting block 43. The connecting groove 44 can be a square groove. The connecting groove 44 is inserted and matched with the hanging basket 5. This is the prior art and will not be described in detail here.

[0023] The fixed base 1 is equipped with an exhaust device 9, which includes an exhaust motor. The exhaust motor is connected to two exhaust pipes 91, and the exhaust pipes 91 are connected to exhaust hoods 92. The two exhaust hoods 92 are symmetrically arranged on both sides of the traveling device 3. They can discharge harmful gases inside the production line during the processing, reduce the impact of gases generated during the production process on the processing, and improve the working environment.

[0024] In some embodiments, the immersion tank 21 is symmetrically provided with support members 22 on both sides. The two support members 22 are respectively inserted into the two ends of the hanging basket 5. The support members 22 can be two fixing blocks with grooves. The two ends of the hanging basket 5 can be provided with protrusions that match the grooves. Through the insertion of the protrusions and the grooves, the hanging basket 5 and the support members 22 can be quickly installed and disassembled, thereby facilitating the insertion and separation of the circuit board on the hanging basket 5 and the immersion tank. This is the prior art and will not be described in detail here.

[0025] In some embodiments, a swing device 7 is provided around the immersion tank group 2, and a support member 22 is provided on the swing device 7. The immersion uniformity is improved by swinging, thereby improving the reaction speed and effect. The swing device may include a drive cylinder, a sliding frame and other structures, which are existing technologies and will not be described in detail here.

[0026] In some embodiments, a vibration device 8 is provided between the immersion tank 21 and the support member 22. The vibration device 8 can be located at the top of the immersion tank 21. The vibration device 8 can drive the support member to vibrate in the height direction, thereby causing the hanging basket that is inserted and cooperated with the support member to vibrate in the height direction, which in turn causes the circuit board located in the immersion tank group 2 to vibrate, helping the medicine to better penetrate into the hole and improve the reaction effect. The vibration device 8 may include structures such as a vibration motor and a vibration spring, which are existing technologies and will not be described in detail here.

[0027] The specific working principle is as follows:

[0028] In practical use, the workpiece to be processed is first placed in the hanging basket 5, and then the hanging basket is immersed in the immersion tank group 2 by the traveling device 3 for processing. After processing, the regulating motor 61 is started, driving the drive gear 62 to rotate, which in turn drives the driven gear 63 and the connecting crossbar 4 to rotate, causing the hanging basket 5 to tilt at a certain angle. At this time, the reaction liquid on the hanging basket 5 flows out faster due to gravity, reducing the residue of reaction liquid on the hanging basket 5 and reducing the consumption of reaction liquid. At the same time, the exhaust device 9 continues to work to remove harmful gases generated during the processing, improving the working environment.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
