2. the whole system is powered by a weak current 12VDC power supply, and the optocoupler module uses a 5VDC power supply, so that the system is safe and reliable;
3. the device successfully solves the problem of unnecessary loss caused by insufficient tension, wire breakage and the like at the pay-off end of the electroplated diamond wire saw production line;
4. the automatic inspection device completely replaces manual inspection, realizes automatic control and improves production efficiency.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: the device comprises a tension bracket 1, a tension wheel 2, an optical coupling module 3, a signal common terminal 4, a conductive contact wheel 5, an insulating sleeve 6, a first guide wheel 7, a second guide wheel 8, a first 9 position, a second 10 position and a tension rod 11.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the utility model relates to a detect diamond wire saw and produce device that line unwrapping wire end tension is not enough or broken string realizes crossing the low position with unwrapping wire end tension and converts the available signal of telecommunication or relay switching value of PLC into. The utility model discloses a tensioning support 1, first leading wheel 7 is installed on the top of tensioning support 1, and the height of second leading wheel 8 needs to be the same with first leading wheel 7. The middle of the tensioning support 1 is hinged with one end of a tension rod 11, the other end of the tension rod 11 is provided with a tensioning wheel 2, and the tensioning wheel 2 is positioned between the first guide wheel 7 and the second guide wheel 8. The diamond wire passes through the first guide wheel 7, the tensioning wheel 2 and the second guide wheel 8 in sequence, the conductive contact wheel 5 is installed on the tensioning support 1 below the tension rod 11, and the contact height of the diamond wire with the tension rod 11 is adjusted through the insulating sleeve 6 on the conductive contact wheel 5. The conductive contact wheel 5 is connected with the anode of the signal input end of the optical coupling module 3, and the cathode of the signal input end of the optical coupling module 3 is connected with the signal common end 4; the optical coupling module is controlled by a PLC and is powered by a 5VDC power supply.
The utility model discloses a theory of operation is: in a normal production environment, the tension F generated by the diamond wire lifts the tension wheel 2, for example, at the first position 9, so that the conductive trolley 5 below the tension rod 11 is not in contact with the tension rod 11; when the tension F of the diamond wire is smaller than or equal to the required value of normal production, the tension rod 11 can be in contact with the conductive wheel 5, if the position II 10 is located, the conductive wheel 5 is conducted with the signal public end 4, the optical coupling module 3 outputs a switching value signal to the PLC after detecting the input of a conduction signal, and the PLC judges whether the diamond wire is broken or insufficient in tension through time comparison.
