Description
Technical field
The utility model is that, on sapphire multi-wire saw apparatus field, more particularly to one kind is multi-thread for sapphire wafer
The broken thread detector of cutting machine.
Background technology
Multi-line cutting machine is used for the production and processing industry of the crisp and hard materials such as sapphire, semiconductor, ceramics.With multi-wire cutting
The fast development of technology is cut, the requirement more and more higher to cutting technique.Broken string can be made multi-line cutting machine suddenly in cutting process
Into a large amount of damaged or obvious stria of generation of sliced materials.
The broken thread detector of traditional multi-line cutting machine substantially has two kinds：
The first is to be powered to loading a voltage on the net in whole diamond wire, passes through the situation of change and detection steel wire of voltage
The break-make of upper electric current come judge whether broken string, but this mode can not effectively avoid broken string after gauze produce evacuate loss, because
Remain to contact with each other after substantial amounts of cutting liquid, and Buddha's warrior attendant thread breakage in diamond wire cutting process to have, voltage change is not obvious,
Even if occur breaking also will not and alarm shut down, or even line largely evacuate cause the situation that whole main shaft roller is scrapped so that
Cause immeasurable loss.
Another is to include detection module, data processing module using a kind of more warning device, and detection module is
Two detection steel wires are arranged on the outside of guide wheel, the pull pressure sensor being connected with detection steel wire is through A/D modules and data processing
Module is connected, and broken string steel wire is got on detection wire under speed and tension force effect with flank speed, makes pull pressure sensor
Output signal transmitting mutation, the output signal of pull pressure sensor is handled by A/D modules and data processing module,
Multi-line cutting machine is controlled to shut down.But the shortcoming of this warning device is due to there is the mixing of coolant and water in cutting environment
Liquid carries out guide wheel in cooling effect, equipment operation and drives current to impact detection steel wire formation with high speed, can equally make
Into voltage pulsation, false alarm is formed, it is impossible to reach the purpose of detection；Pull pressure sensor price is somewhat expensive simultaneously, and in humidity
It is very easy to damage in environment.
Utility model content
Main purpose of the present utility model be to overcome it is of the prior art it is not enough there is provided a kind of simple in construction, cost it is low,
Sensitivity is high, can accurately and timely send the broken thread detector that broken string judges signal.In order to solve the above technical problems, this practicality
New solution is：
A kind of broken thread detector for sapphire wafer multi-line cutting machine is provided, the broken string of diamond wire can be detected, it is blue
Jewel chip multi-line cutting machine includes casing, home roll supporting plate, main shaft roller, servomotor, described many for sapphire wafer
The broken thread detector of wire cutting machine includes burn out detection bar, burn out detection fixed plate；
Home roll supporting plate is provided with two pieces, is connected respectively with the fixed casing of sapphire wafer multi-line cutting machine, and two
Block home roll supporting plate be arranged in parallel；The two ends of main shaft roller are respectively erected in corresponding home roll supporting plate；Used on main shaft roller
In winding diamond wire gauze, main shaft roller is driven by servomotor；
The burn out detection bar is arranged on the underface of main shaft roller, and the axle of the axis and main shaft roller of burn out detection bar
Line is parallel；Burn out detection bar is used to sense broken string (burn out detection bar is to sense the sensing component of broken string), when on line roller
When diamond wire is got on burn out detection bar, the change of burn out detection bar both sides resistance value can be caused；
The top edge of the burn out detection fixed plate is provided with hole slot, and the two ends difference frame of burn out detection bar is in two pieces of broken string inspections
In the hole slot for surveying fixed plate, and two pieces of burn out detection fixed plates are connected with corresponding home roll supporting plate respectively；Burn out detection is fixed
Plate is the burn out detection fixed plate of isolation material, it is ensured that burn out detection bar is realized with home roll supporting plate and casing to insulate.
As a further improvement, the installation site of burn out detection bar from a distance from diamond wire on main shaft roller for 20~
50mm。
As a further improvement, in the broken thread detector for sapphire wafer multi-line cutting machine, broken string inspection
The setting quantity of measuring staff is identical with the quantity of main shaft roller, and the two ends of every burn out detection bar are erected at independent burn out detection
In fixed plate.
As a further improvement, the broken thread detector for sapphire wafer multi-line cutting machine also includes detection
Equipment, detection device include signal wire, terminal, screw, detection circuit, detection circuit by signal wire, terminal with
Burn out detection bar is connected；
The detection circuit refers to the circuit that is handled the voltage signal at burn out detection bar two ends, burn out detection bar and
Detection circuit is connected to form loop, when the Buddha's warrior attendant thread breakage on main shaft roller, resistance value can be caused to become on burn out detection bar
Change, and then specific voltage pulse signal is triggered in detection circuit.It can control to be used to drive master by this voltage pulse signal
The servomotor stalling of axis roller rotation, the function can realize that PLC module passes through by adding PLC module in detection device
Signal wire, terminal and burn out detection bar are connected, and control to watch using the change of the voltage signal at burn out detection bar two ends
Take whether motor stalls.
Operation principle of the present utility model：Burn out detection bar two ends are connected with detection circuit, loop are formed, when equipment is run
Burn out detection bar is powered (DC24V), and when breaking, diamond wire and the burn out detection bar of fracture collide so that broken string
The resistance value in the whole loop of detection bar changes, so that a voltage pulse signal is excited in detection circuit, this pulse letter
After number being recognized by PLC, the occurrence of just judging broken string, and then the motor stalling of drive shaft line roller rotation is controlled, prevent
The generation further damaged.By verifying, the cutting fluid during diamond wire cutting sapphire in splash to burn out detection bar
The change of burn out detection rods circuit resistance value can be caused, but this change numerical value and broken string caused by diamond wire broken string are not one
The order of magnitude (cutting liquid trigger change in resistance megaohm the order of magnitude, diamond wire trigger change in resistance kilo-ohm quantity
Level), then the such difference of detection circuit identification filters out the voltage pulse signal triggered by cutting liquid, it is ensured that do not occur
Erroneous judgement, so as to greatly improve the degree of accuracy of detection.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is not only simple in structure, cost is low, and sensitivity is high, can accurately and timely be sent broken string and be judged letter
Number, so as to send alert notification operating personnel shutdown processing, or directly control to shut down by the control circuit of multi-line cutting machine, drop
The low risk of mistakenly stop machine, it is to avoid the generation of vaccuum phenomenon.
