Description

Technical Field

[0001] The utility model relates to the field of electrostatic brushes, in particular to an electrostatic brush. Background Art

[0002] Chips are usually made of single-crystal silicon wafers. After the wafer is cut, multiple small grains, namely IC chips, are formed. Usually, multiple IC chips are fixed on the material strip at intervals with a substrate and pulled together. During the production process, the product will have static standards. In order to ensure the removal of dust, an electrostatic brush is used. The existing electrostatic brush adopts an integrated structure. The front end of the brush loses hair and needs to be replaced as a whole. The handle is in the normal position, which is wasteful. Although there are electrostatic brushes with replaceable brush heads on the market, they are positioned with screws. Repeated disassembly and assembly of the screws can easily cause the screws to slip, resulting in the brush head being unable to be effectively fixed. In order to solve the above problems, we propose an electrostatic brush. Utility Model Content

At this time, the positioning rod 6 will be separated from the positioning groove 5, and the brush head 3 can be directly pulled out, and the connecting rod 4 on one side of the new brush head 3 can be inserted into the inside of the brush holder 1. The two fixing plates 7 are loosened, and the compressed spring 8 will push the fixing plate 7 and the positioning rod 6 to reset, so that the positioning rod 6 and the positioning groove 5 are snapped together, thereby limiting the brush head 3; this replacement method is simple and convenient, and there will be no thread slipping phenomenon when replacing screws on the market.

[0027] Furthermore, the electrostatic monitoring component 9 includes an electrostatic sensor 91, which is electrically connected to a current adsorption block 92. The current adsorption block 92 is fixedly mounted inside the brush holder 1, and one side of the current adsorption block 92 is in contact with the conductive block 10. Through the setting of the electrostatic monitoring component 9, the electrostatic sensor 91 is used to monitor the current intensity of static electricity: the unit is volts per meter V / m, and the monitoring value is forwarded to the display screen 11 for display; the current adsorption block 92 is used to absorb the static current transmitted by the conductive block 10, so that the electrostatic sensor 91 can monitor the static current intensity; the current adsorption block 92 is a prior art and its principle of monitoring static electricity will not be elaborated here; and after the current adsorption block 92 monitors the static data, the display screen 11 displays the monitoring value, which is also a prior art and will not be elaborated here.
