Description
Technical field
The utility model belongs to machine field, relates in particular to a kind of Hall subassembly pick-up unit.
Background technology
Detect Hall subassembly and whether can produce hall signal, whether qualified, generally finish by oscillograph at present, this detection method inconvenient operation, testing result are not directly perceived, and work efficiency is low.
Summary of the invention
The utility model provide a kind of easy to operate, testing result intuitively, the Hall subassembly pick-up unit of greatly increasing work efficiency, mainly solve the detecting operation inconvenience of existing Hall subassembly, the technical matters that testing result is directly perceived inadequately, work efficiency is low.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: the utility model comprises single-chip microcomputer, signal indicating member, motor, the magnet steel that links to each other with motor rotor and the power conversion unit of working power is provided for whole detection device, the input pin of described single-chip microcomputer links to each other with the hall signal output pin of tested Hall subassembly, the output pin of described single-chip microcomputer links to each other with the signal indicating member, single-chip microcomputer internal memory contain pick-up unit working routine.Hall subassembly near rotary magnetic steel can produce hall signal, catches this signal and process computing with single-chip microcomputer, and single-chip microcomputer has an output, goes the drive signal indicating member to obtain testing result with this.During detection, two operating voltage input pins with tested Hall subassembly link to each other energized with power supply unit earlier, the rotation of motor drives magnet steel is again with the close magnet steel of tested Hall subassembly, if the signal indicating member has indication, illustrate that then this Hall subassembly has hall signal output, is certified products; If the signal indicating member does not have indication, illustrate that then this Hall subassembly does not have hall signal output, is unacceptable product.Take off this Hall subassembly, the signal indicating member does not have indication, carries out the detection of next Hall subassembly then.Easy to operate, testing result is directly perceived, increases work efficiency.
As preferably, described signal indicating member is a LED 2, and the output pin of described single-chip microcomputer is through the positive pole of resistance R 2 sending and receiving optical diode LED2, the minus earth of LED2.When tested Hall subassembly when the rotary magnetic steel, if any hall signal output, then LED 2 is bright, on the contrary LED2 does not work.Whether differentiate Hall subassembly by the bright of LED 2 and not working has hall signal output, make testing result come into plain view, more directly perceived, and realize also more convenient.
As preferably, another output pin of described single-chip microcomputer links to each other with the power supply indicating member, and described power supply indicating member is a LED 1, and the positive pole of LED 1 connects single-chip microcomputer through resistance R 1, the minus earth of LED1.After the power supply unit energising, this output pin output signal driven for emitting lights diode (LED) 1 of single-chip microcomputer, LED1 lights; Powered-down, LED1 goes out.The power supply indicative function of 1 whole detection device of LED reminds user's device to be in "on" position, can begin testing, also guarantees the security of testing.
As preferably, described power conversion unit is by DC power supply.Can select the DC power supply of 5～20V for use.
The beneficial effects of the utility model are: utilize Hall subassembly can produce hall signal, catch this signal and process computing with single-chip microcomputer near rotary magnetic steel, and control signal of single-chip microcomputer output, the driven for emitting lights diode is lighted.Whether have hall signal output, thereby determine whether Hall subassembly is qualified, easy to operate if differentiating Hall subassembly by the bright of light emitting diode and not working, testing result comes into plain view, very directly perceived, improved work efficiency greatly.
