Specific embodiment
It is new below in conjunction with this practicality to make purpose, technical scheme and the advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in the utility model embodiment
The embodiment stated is a part of embodiment of the utility model, rather than the embodiment of whole.Based on the enforcement in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Fig. 1 is the floor map of the utility model electroplanting device one embodiment, as shown in figure 1, the electroplanting device bag
Include:
The negative electrode of strip flies target 1;Multiple vibrations motors 2;One of vibrations motor is arranged on the centre that negative electrode flies target
Position;Remaining vibrations motor is evenly distributed on negative electrode and flies on target, equal with the plating plate transmission for flying to be hung on target to the negative electrode
Even vibration energy.
In electroplating activity, above-mentioned vibrations motor switches on power, and produces vibration energy, and wherein negative electrode flies the shake at target two ends
The vibration energy that dynamic motor is produced passes to negative electrode and flies target by the two ends that negative electrode flies target, and the vibration energy flies the two of target in negative electrode
Intensity and amplitude are most strong during end, and when flying the centre position of target near negative electrode, the intensity and amplitude of the vibration energy is gradually weak;It is cloudy
The vibration energy for extremely flying the vibrations motor generation in target centre position enhances intensity and the width that the centre position of the winged target of negative electrode is shaken
Uniform vibration energy is produced on degree, therefore the winged target of whole negative electrode, and the uniform vibration energy is passed to into negative electrode and flown on target
The plating plate of suspension.
