Description

Technical Field

[0001] The utility model belongs to the field of auxiliary equipment in the process of manufacturing printed circuit boards, and in particular relates to an inclined hanging board device for PCB immersion gold production. Background Art

[0002] During the processing of printed circuit boards, there is a process of PCB board nickel-gold plating or thick gold electroplating. In the production of PCB nickel-gold plating, the PCB board will take out the gold solution when it comes out of the gold cylinder. In conventional production, when the PCB board after gold plating is lifted out of the gold cylinder by a crane, the PCB board and the crane beam are kept horizontal. When it comes out of the gold cylinder, the solution drips from the entire bottom of the board. Some solution will remain on the bottom of the PCB board and cannot be completely dripped back into the cylinder, resulting in a waste of solution and increased costs. In the subsequent washing process, the amount of water will increase, and the direct discharge of washing water will also cause environmental pollution problems;

The inclined hanging plate device for PCB immersion gold production includes: a body of the inclined hanging plate device for PCB immersion gold production including a lifting beam; a first mounting plate, the first mounting plate is fixedly mounted on the bottom of the lifting beam; a second mounting plate, the second mounting plate is fixedly mounted on the bottom of the lifting beam; a limit rod, the limit rod is fixedly mounted on the side where the first mounting plate and the second mounting plate are close to each other; a first hanger, the first hanger is fixedly mounted on the first mounting plate; a slider, the slider is slidably mounted on the limit rod;

[0004] The above comparative documents have the following problems:

[0005] The existing hanging board device mainly relies on the tilt angle of the PCB board and its own gravity for the dripping of the liquid, which leads to relatively low dripping efficiency. The limitations of this method are mainly reflected in the following aspects:

[0006] The dripping speed is uncontrollable: It is impossible to accurately control the dripping speed of the liquid medicine by relying solely on gravity dripping. Different dripping speeds may be required in different dripping stages, and it is difficult for existing technologies to meet this requirement.

[0007] The dripping amount is difficult to control: Since the dripping speed is uncontrollable, the dripping amount is also difficult to control;

[0008] Low production efficiency: Relying solely on gravity dripping, the dripping speed is slow and the efficiency is low; it may lead to a decrease in production capacity and increase production costs.

[0009] High requirements on the properties of the liquid medicine: For some liquid medicines with high viscosity or large surface tension, relying solely on gravity dripping may not be effective, and uneven dripping or dripping failure may easily occur. Utility Model Content

[0028] It should be noted that, since the existing hanging plate device mainly relies on the inclination angle and self-gravity of the PCB board for the dripping of the medicine liquid, which leads to the problem of relatively low dripping efficiency, this solution adopts a variety of means to optimize the dripping effect of the medicine liquid; the hydraulic rod 902 is used to adjust the height of the clamp 903, so that the bottom side of the PCB board presents an optimal inclination angle, thereby increasing the dripping speed of the medicine liquid; at the same time, the servo motor 8 drives the receiving cross plate 7 to rotate, thereby further realizing the dripping speed of the medicine liquid on the PCB board; in addition, by blowing air towards the PCB board through two fans 10, the medicine liquid can be promoted to drip evenly and quickly into the gold sink 1, thereby avoiding the accumulation and retention of the medicine liquid; these designs help to improve production efficiency and product quality.

[0029] Specifically, in this embodiment, this scheme mainly includes a gold sinking tank 1; an assembly rack 2 arranged above the gold sinking tank 1; a group of slide grooves 3 symmetrically arranged between the assembly racks 2; a same horizontal screw slide 4 is slidably matched between the two slide grooves 3; the motor of the horizontal screw slide 4 drives its moving end to drive the longitudinal screw slide 5 to move horizontally according to a preset path; the longitudinal screw slide 5 drives its moving end through the motor to further control the position of the connecting seat 6, so as to accurately adjust the position of the clamp; through the above two-stage motor drive, the position of the clamp can be accurately adjusted; this enables the staff to easily fix the two side edges of the PCB board to the clamp 903;

[0030] The hydraulic rod 902 is used to drive one of the clamps 903 to adjust the height, so that the bottom side of the PCB board can present an optimal tilt angle and increase the dripping speed of the medicine. The servo motor 8 is used to drive the receiving cross plate 7 to rotate, and by driving the clamping part to rotate, the dripping speed of the PCB board medicine is further achieved.

[0031] In a further preferred embodiment of the present invention, Figure 2-3 As shown, fans 10 are disposed on both inner walls of the assembly frame 2, and the air outlets of the two fans 10 are disposed opposite to each other.

[0032] In this embodiment, two fans 10 are used to blow air toward the PCB board, which can effectively improve the dripping effect of the medicine. The wind force can promote the medicine to drip evenly and quickly, avoiding the accumulation and retention of the medicine, thereby improving production efficiency and product quality.

[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a group of driving cylinders 11 are symmetrically arranged on the top of the assembly frame 2 , and the output ends of the two driving cylinders 11 are connected to the top side of the transverse screw slide 4 .

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, one of the connecting blocks 901 is slidably matched with the receiving transverse plate 7.

[0038] In this embodiment, a sliding connection block 901 is provided to facilitate adjustment of the distance between two connection blocks 901 , thereby clamping PCB boards of different sizes.

[0039] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the outer side of the clamping member is provided with an anti-corrosion coating.
