Abstract
A kind of antistatic workbench, described workbench is also provided with a battery and a LED, the positive pole of battery connects the positive pole of LED by live wire, the negative pole of battery connects the negative pole of LED by zero line, described zero line overlap joint ground wire, for ground connection, described workbench, ESD mat and esd wrist strap are all overlapped on described zero line by electric wire, its effect prevents ground wire grounded badly to impact production, according to bright not the working of LED, operating personnel can judge whether ground connection goes wrong.
Description
Technical field
The utility model relates to a kind of Precision Manufacturing Technology field, especially a kind of antistatic workbench.
Background technology
Need to carry out static elimination to process equipment, workbench or even human body in the course of processing of many precise parts.Such as Chinese patent discloses a kind of anti-static device, application number: 201210496095.1, the applying date: 2012-11-28, a kind of anti-static device, is characterized in that: comprise a workbench, place mat work top ESD mat and be arranged on the ESD wrist strap of antistatic of workbench side; By operating personnel are worn ESD wrist strap ground connection, work top place mat ESD mat ground connection and machine, the direct earth connection of workbench metal object mode eliminate electrostatic.
Technique scheme effectively eliminates the issuable electrostatic in each position in production process, but Problems existing is, when ground path goes wrong (such as disconnection, loose contact etc.), operating personnel cannot perception in time.If now operating personnel continue processing, significant impact may be caused to the quality of product.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of can whether perception ground path good at any time antistatic workbench.
The technical solution of the utility model is:
A kind of antistatic workbench, comprise a workbench, place mat work top ESD mat and be arranged on the ESD wrist strap of antistatic of workbench side, it is characterized in that, described workbench is also provided with a battery and a LED, the positive pole of battery connects the positive pole of LED by live wire, the negative pole of battery connects the negative pole of LED by zero line, described zero line overlap joint ground wire, for ground connection, described workbench, ESD mat and esd wrist strap are all overlapped on described zero line by electric wire, its effect prevents ground wire grounded badly to impact production, according to bright not the working of LED, operating personnel can judge whether ground connection goes wrong.
For reducing error in judgement further, described workbench, ESD mat and esd wrist strap all can be overlapped on LED negative pole, such whole piece zero line all can be considered that ground wire is not (although LED loop comprises whole piece ground wire completely, but ground contact is bad generally occurs over just the section of wriggling and being arranged in workbench confined space), as long as LED is bright just illustrate that ground connection is good.
Further, described live wire is provided with switch, for the disconnection of control circuit, and the open-circuit line when equipment quits work, saves energy.
The beneficial effects of the utility model are: by the setting in LED loop, make operating personnel can the anti-static grounding of perception workbench at any time whether good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is circuit diagram of the present utility model.
In figure, 1-workbench, 2-ESD mat, 3-LED lamp, 4-battery.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, a kind of antistatic workbench, comprise a workbench 1, place mat workbench 1 ESD mat 2 and be arranged on the ESD wrist strap of antistatic of workbench 1 side, it is characterized in that, described workbench is also provided with battery 4 and a LED 3, the positive pole of battery 4 connects the positive pole of LED 3 by live wire, the negative pole of battery 4 connects the negative pole of LED 3 by zero line, described zero line overlap joint ground wire, for ground connection, described workbench 1, ESD mat 2 and esd wrist strap are all overlapped on described zero line by electric wire, its effect prevents ground wire grounded badly to impact production, according to bright not the working of LED, operating personnel can judge whether ground connection goes wrong.
For reducing error in judgement further, described workbench 1, ESD mat 2 and esd wrist strap all can be overlapped on LED 3 negative pole, such whole piece zero line all can be considered that ground wire is not (although LED loop comprises whole piece ground wire completely, but ground contact is bad generally occurs over just the section of wriggling and being arranged in workbench confined space), as long as LED is bright just illustrate that ground connection is good.
Described live wire is provided with switch, for the disconnection of control circuit, and the open-circuit line when equipment quits work, saves energy.
What describe in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
