Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic elimination of machines, and particularly relates to an electrostatic elimination device for an automatic machine. Background Art

[0002] When a battery automatic machine produces battery wafers, since the battery wafers often carry static electricity, the battery wafer mounter may stop production abnormally. Therefore, effective static electricity elimination is one of the important criteria for the stable production of the machine.

[0003] Currently, the static electricity on the battery automatic machine is mostly eliminated by an ion air bar. However, this method of eliminating static electricity has several problems:

[0004] 1. The ion air bar detects and releases ions unstably, and when the static electricity detection exceeds the standard, the target of reducing static electricity cannot be achieved;

[0005] 2. The area blown by the ion air bar is too small, and the area becomes linear after being blown by the air bar, resulting in a defect in full coverage;

[0006] 3. When debris falls during the operation of the machine, there is a risk of blocking the air outlet of the ion air bar. Content of the Utility Model

[0007] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to provide an electrostatic elimination device for an automatic machine, which can not only effectively reduce the static electricity of battery wafers, but also effectively stabilize production, and improve the use efficiency of the machine.

[0016] 1. An ion generator and a blower impeller are provided. The air with positive and negative charges is blown towards the machine table under the action of multiple blower impellers. When the charge on the surface of the machine table is negative, it will attract the positive charges in the air flow; when the charge on the surface of the machine table is positive, it will attract the negative charges in the air flow. When the equal amount of positive and negative charges come into contact, electrical neutralization can be achieved, and the static electricity on the machine table can be stably eliminated.
