Abstract
The utility model discloses a broken wire detection device of a multi-wire sawing machine which has high sensitivity and is suitable for various kinds of mortars and liquids. The broken wire detection device comprises a detection module and a data processing module (7), and is characterized in that the detection module comprises fixed bases arranged on a frame and used for mounting a roller (1); a fixing block (3) and a pull pressure sensor (5) are respectively arranged on the fixed bases mounted on both ends of the roller (1); a detection steel wire (4) is connected between the fixing block (3) and the pull pressure sensor (5); and an output signal of the pull pressure sensor (5) is transmitted to the data processing module (7) for processing through an A/D (Analog to Digital) module (6). The broken wire detection device provided by the utility model has simple structure and high sensitivity, is independent of electrical signals, can realize effective, quick and accurate broken wire detection, can be used for occasions of conductive mortar solutions, and can effectively ensure the accuracy and timeliness of the detection result.
Description
Technical field
The utility model relates to a kind of multi-line cutting machine, specifically a kind of broken thread detector of multi-line cutting machine.
Background technology
Multi-line cutting machine is multiplex in semiconductor, pottery, magnetic material and sapphire production and processing industry.Along with the fast development of multi-wire saw technology, more and more higher to the requirement of cutting technique.Multi-line cutting machine unexpected broken string in cutting process can cause a large amount of breakages of sliced materials or produce obvious stria.At present, the wire break detection method that adopts is electrical signal detection method and tension force detection method.The electrical signal detection method easily produces erroneous judgement when mortar conducts electricity, and the tension force detection method can produce time-delay when the middle broken string of gauze.
Summary of the invention
The purpose of this utility model is to provide a kind of high sensitivity, is applicable to the broken thread detector of the multi-line cutting machine of various mortars and liquid.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of broken thread detector of multi-line cutting machine, it comprises detection module, data processing module, described detection module comprises and is located on frame the holder that is used for installing roller, be arranged on the holder at roller two ends and be respectively equipped with fixed block, pull pressure sensor, be connected with the detection wire between fixed block and pull pressure sensor, the output signal of pull pressure sensor is sent into data processor module through the A/D module and is processed.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, highly sensitive, do not rely on the signal of telecommunication, can realize detecting effectively quickly and accurately the steel wire broken string, can be used for the occasion of mortar solution conductivity, effectively guarantee accuracy and the instantaneity of testing result.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of broken thread detector of multi-line cutting machine, it comprises detection module, data processing module 7, described detection module comprises and is located on frame the holder that is used for installing roller 1, be arranged on the holder at roller 1 two ends and be respectively equipped with fixed block 3, pull pressure sensor 5, be connected with between fixed block 3 and pull pressure sensor 5 and detect wire 4, the output signal of pull pressure sensor 5 is sent into data processor module 7 through A/D module 6 and is processed.
The utility model is in the both sides of two rollers and be equipped with on parallel direction with it and detect wire 4, during detection, detects wire 4 and is tightened up between fixed block 3 and pull pressure sensor 5.When in cutting process, wire 2 broken strings on roller 1, under the effect of speed and tension force, wire 2 will be thrown away, broken string steel wire 8 is beaten on aside detection wire 4 with high speed, make and detect wire 4 generation Bending Deformations, the pulling force that detects simultaneously 4 pairs of pull pressure sensor 5 of wire will produce the step sudden change.At this moment; data processor module 7 quick samplings that comprise CPU; the sudden change of pull pressure sensor 5 output signals detected in time; the output signal of pull pressure sensor 5 is sent into data processor module 7 through A/D module 6 and is processed; can find immediately the situation of wire 2 broken strings, and be controlled the shutdown of multi-line cutting machine by data processor module 7.
The utility model is compared with other checkout gear, has the higher degree of accuracy and sensitivity, has eliminated erroneous judgement, and is applicable to the occasion of mortar and liquid conduction.
