Abstract
The utility model relates to a kind of scribing machine main shaft carbon brush abrasion protection system, comprises main shaft, carbon brush, carbon brush holder, cylinder, choke valve, magnetic valve, I/O controller.The utility model also provides the course of work of above-mentioned scribing machine main shaft carbon brush abrasion protection system, comprise the steps: 1) when not carrying out surveying high, cylinder intake is turned off by magnetic valve, cylinder axis drives carbon brush holder to shrink, at this moment carbon brush does not contact with main shaft axle core, does not does not wear and tear during main shaft High Rotation Speed to carbon brush; 2) when needing to survey high, Controlling solenoid valve opens cylinder ventilation, and cylinder drives carbon brush holder slowly to stretch out, and carbon brush contacts with main shaft axle core and forms loop, and it is generally very short to survey the high time, and the wear extent of carbon brush can control in very little scope.The utility model can ensure that main shaft and carbon brush do not contact when accident height, thus substantially reduces the wearing and tearing of carbon brush, improves the life-span of carbon brush and surveys high stability.
Description
Technical field
The utility model relates to main shaft carbon brush abrasion protection system, is retracted by main shaft carbon brush, prevent carbon brush Fast Wearing when main shaft rotation and accident height.
Background technology
Cutting machine encapsulates key equipment after a kind of semiconductor, and its effect is that Device singulation is become single circuit unit.The working mechanism of cutting machine be emery wheel blade driven High Rotation Speed to produce cutting force to go to split device by spindle motor.Contact with main shaft axle core by carbon brush when blade survey is high and form loop, carbon brush can wear and tear when main shaft High Rotation Speed, and the time has worn and torn short and the loose contact of axle core once long its, and the carbon dust worn and torn is deposited in the high stability of shaft end impact survey.
Utility model content
The purpose of this utility model is to provide the anti-wear system of cutting machine main shaft carbon brush and the course of work thereof, can ensure that carbon brush does not contact with axle core when accident height, reduces the wear extent of carbon brush, improves the life-span of carbon brush and surveys high stability.
For achieving the above object, the utility model provides a kind of main shaft carbon brush abrasion protection system, comprises main shaft, carbon brush, carbon brush holder, cylinder, choke valve, magnetic valve, I/O controller; Carbon brush is placed in carbon brush holder after being connected by spring, and the front end of carbon brush is stretched out to contact with the rear end face of main shaft axle core and formed path; Telescopic-cylinder axle is connected with carbon brush holder and drives carbon brush holder to move forward and backward; Cylinder is single-acting cylinder, i.e. an air inlet, and when air inlet has air pressure, cylinder stretches out, and during closedown air pressure, cylinder shrinks and goes back, and cylinder intake place has throttle valve control cylinder to stretch out speed; Main frame realizes cylinder contractive action by the folding of I/O controller and solenoid control cylinder air pressure.
Preferably, the cylindrical of gradient made by carbon brush, and carbon brush holder inwall is processed into it the cylindrical hole of gradient.
Preferably, cylinder intake adds choke valve.
The utility model also provides the course of work of above-mentioned scribing machine main shaft carbon brush abrasion protection system, comprises the steps:
1) when not carrying out surveying high, turn off cylinder intake by magnetic valve, cylinder axis drives carbon brush holder to shrink, and at this moment carbon brush does not contact with main shaft axle core, does not does not wear and tear during main shaft High Rotation Speed to carbon brush;
2) when needing to survey high, Controlling solenoid valve opens cylinder ventilation, and cylinder drives carbon brush holder slowly to stretch out, and carbon brush contacts with main shaft axle core and forms loop, and it is generally very short to survey the high time, and the wear extent of carbon brush can control in very little scope.
Advantage of the present utility model and beneficial effect are: provide a kind of scribing machine main shaft carbon brush abrasion protection system and the course of work thereof; when can meet accident height, main shaft does not contact with carbon brush; reduce the wear extent of carbon brush; improve the carbon brush life-span; reduce carbon dust simultaneously and be deposited in rear-end of spindle, improve and survey high stability.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the utility model control chart.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The technical scheme that the utility model is specifically implemented is:
As shown in Figure 1, a kind of scribing machine main shaft carbon brush abrasion protection system, comprises main shaft axle core 1, carbon brush 2, carbon brush holder 3, cylinder 4, choke valve 5, magnetic valve 6 and controller 7; Carbon brush 2 is placed on carbon brush holder 3 li after being connected by spring, the front end of carbon brush 2 is stretched out to contact with the rear end face of main shaft axle core 1 and formed path; Cylinder 4 telescopic shaft is connected with carbon brush holder 3 and drives carbon brush holder 3 to move forward and backward; Cylinder 4 is single-acting cylinder, i.e. an air inlet, and when air inlet has air pressure, cylinder 4 stretches out, and during closedown air pressure, cylinder 4 shrinks and goes back, and cylinder 4 air inlet place has choke valve 5 control cylinder 4 to stretch out speed; Main frame realizes cylinder 4 contractive action by the folding of I/O controller 7 and magnetic valve 6 control cylinder 4 air pressure.
The utility model also provides the course of work of above-mentioned scribing machine main shaft carbon brush abrasion protection system, comprises the steps:
1) when not carrying out surveying high, turn off cylinder 4 air inlet by magnetic valve 6, cylinder axis drives carbon brush holder 3 to shrink, and at this moment carbon brush 2 does not contact with main shaft axle core 1, to carbon brush 2 not wearing and tearing during main shaft High Rotation Speed;
2) when needing to survey high, Controlling solenoid valve 6 is opened cylinder 4 and is ventilated, and cylinder 4 drives carbon brush holder 3 slowly to stretch out, and carbon brush 2 contacts with main shaft axle core 1 and forms loop, and it is general very short to survey the high time, and the wear extent of carbon brush 2 can control in very little scope.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
