Description

Technical Field

[0002] In electroplating and etching processes, the cleaning process is a crucial step in ensuring product quality. The concentration of the cleaning solution directly affects the cleaning effect; if the concentration is too low, it may not be able to effectively remove contaminants, affecting subsequent processes. Traditional electroplating and etching cleaning devices have a fixed cleaning solution concentration, which is difficult to adapt to different materials, process requirements, and changes in cleaning solution concentration during use. Moreover, the uniformity of the cleaning solution distribution within the cleaning device is also difficult to guarantee, easily affecting the consistency of the cleaning effect. In addition, existing cleaning devices generally only have a single cleaning frame. When removing the cleaning frame from the cleaning device to replace the electroplated and etched items, the cleaning time of the cleaning device will be wasted, and the work efficiency needs to be improved. Therefore, there is an urgent need for an electroplating and etching cleaning device with adjustable cleaning solution concentration. Utility Model Content

[0029] Metering pump 8, there are two metering pumps 8, which are respectively installed on additive pipe 3 and liquid inlet pipe 4, and the metering pump 8 is electrically connected to controller 7;

[0030] Motor 9 is fixedly installed at the bottom of the cleaning tank 1. Motor 9 is electrically connected to controller 7. A high-efficiency stirring mechanism 10 connected to motor 9 is provided in the cleaning tank 1 at the position below the cleaning frame 2. A synchronous shifting mechanism 11 connected to the two cleaning frames 2 is provided on the cleaning tank 1.

[0031] The high-efficiency stirring mechanism 10 includes:

[0032] Fixed cylinder 10-1 is fixedly installed on the inner bottom wall of cleaning tank 1, and fixed cylinder 10-1 is rotatably sleeved on the output shaft of motor 9 through a sealed bearing. Rotating head 10-2 is rotatably sleeved on fixed cylinder 10-1 through a sealed bearing. The output shaft of motor 9 is fixedly connected to rotating head 10-2.

[0033] A stirring shaft 10-3, comprising several shafts, is rotatably mounted on a rotating head 10-2 via sealed bearings with equal rounded corners. A driven bevel gear 10-4 is fixedly sleeved at one end of the stirring shaft 10-3, and a fixed bevel gear 10-5 is fixedly sleeved on a fixed cylinder 10-1, with the fixed bevel gear 10-5 located inside the rotating head 10-2. The driven bevel gears 10-4 are all meshed with the fixed bevel gears 10-5. When the first motor 9 drives the stirring shaft 10-3 to rotate inside the cleaning tank 1 via the rotating head 10-2, it achieves mixing and stirring of the cleaning liquid. At the same time, the cooperation of the fixed cylinder 10-1, the fixed bevel gears 10-5, and the driven bevel gears 10-4 allows the stirring shaft 10-3 to rotate, thereby improving the mixing effect of the cleaning liquid.

[0034] The synchronous shifting mechanism 11 includes:

[0035] The second motor 11-1 is fixedly installed on the front side wall of the cleaning tank 1. The second motor 11-1 is electrically connected to the controller 7. A worm gear 11-2 is fixedly installed on the output shaft of the second motor 11-1.

[0036] Two connecting frames 11-5 are fixedly installed on the front and rear sides of the two cleaning frames 2, respectively, and the connecting frames 11-5 abut against the cleaning tank 1. One end of each of the three rotating rods 11-3 is fixedly equipped with a connecting rod 11-6. Reinforcing ribs 13 are fixedly installed on the side walls of the connecting rods 11-6, and several reinforcing plates 14 connected to the connecting rods 11-6 are fixedly installed on the side walls of the reinforcing ribs 13. Through the cooperation of the reinforcing ribs 13 and the reinforcing plates 14, the structural strength of the connecting rods 11-6 can be improved, enabling the connecting rods 11-6 to have stronger load-bearing capacity. The connecting rods 11-6 on the front and rear sides are rotatably connected to the two connecting frames 11-5 via rotating shafts. The front side wall of the cleaning tank 1...

The protective shell 12 can protect the second motor 11-1, worm gear 11-4 and worm 11-2, and prevent external objects from accidentally contacting the worm gear 11-4 and worm 11-2 and causing the worm gear 11-4 and worm 11-2 to jam. One end of the worm 11-2 is rotatably connected to the protective shell 12 via a bearing. The second motor 11-1 is fixedly connected to the inner wall of the protective shell 12. The rotatable connection between the worm 11-2 and the protective shell 12 can effectively improve the rotational stability of the worm 11-2.

[0037] When using this invention, the concentration monitor 6 can monitor the concentration of the cleaning solution in the cleaning tank 1. When it is necessary to adjust the concentration of the cleaning solution, the amount of additive in the cleaning tank 1 can be discharged through the metering pump 8 on the additive pipe 3, thereby controlling the concentration of the cleaning solution in the cleaning tank 1. Then, the first motor 9 can be started, which drives the rotating head 10-2 to rotate. The rotating head 10-2 drives several stirring shafts 10-3 to rotate in the cleaning tank 1. At the same time, through the meshing of the fixed bevel gear 10-5 and the driven bevel gear 10-4, the driven bevel gear 10-4 can drive the stirring shaft 10-3 to rotate, providing more efficient mixing and stirring of the cleaning solution in the cleaning tank 1, so as to ensure the uniformity of the cleaning solution concentration in all parts of the cleaning tank 1. Each cleaning frame 2 is filled with electroplated etched material. After the electroplated etched material in the cleaning frame 2 located in the cleaning box 1 is cleaned, the second motor 11-1 can be started. The second motor 11-1 drives the worm gear 11-2 to rotate. By using the meshing of the worm gear 11-2 and the worm wheel 11-4, the worm wheel 11-4 can drive the front rotating rod 11-3 to rotate. Through the cooperation of the connecting rod 11-6 and the two rear rotating rods 11-3, the cleaned electroplated etched material can be moved to the outside of the cleaning box 1 along with the placed cleaning frame 2. The other cleaning frame 2 can move the uncleaned electroplated etched material into the cleaning box 1 for cleaning. This allows the electroplated etched material in the cleaning frame 2 on one side to be cleaned while the electroplated etched material in the other cleaning frame 2 can be replaced.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] 1. By cooperating with the concentration monitor 6, controller 7 and metering pump 8, the concentration of cleaning solution in cleaning tank 1 can be adjusted as needed;

[0040] 2. Through the cooperation of motor 9 and high-efficiency stirring mechanism 10, the cleaning liquid in the cleaning tank 1 can be efficiently mixed and stirred to ensure the uniformity of the concentration of the cleaning liquid in the cleaning tank 1.

[0041] 3. With the cooperation of the synchronous shifting mechanism 11, the synchronous shifting control of the two cleaning frames 2 can be realized, thereby improving the cleaning effect of electroplated etched objects.

[0042] 4. By combining the reinforcing ribs 13 and rib plates 14, the structural strength of the connecting rod 11-6 can be improved, enabling the connecting rod 11-6 to have stronger load-bearing capacity.

[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
