Abstract

The utility model relates to the technical field of wire cutting machines, in particular to a cutting mechanism, a wire saw unit and a wire cutting machine, and aims to solve the problem that an excessive radial load is required to be born during cutting operation due to the fact that a compression roller set in the existing cutting mechanism directly contacts two wire meshes. Therefore, the cutting mechanism provided by the utility model has the advantages that the pressing roller set is arranged on one side of the second wire mesh, which is far away from the first wire mesh, and the second wire mesh is pressed towards the first wire mesh under the action of the first wire grooves on the pressing roller set, so that the coplanarity of the first wire mesh and the second wire mesh is realized, and the height of a workpiece to be cut is not limited by the distance between the double-layer wire meshes in the prior art. In addition, the groove depth of the second wire groove is set to be larger than the groove depth of the first wire groove, so that when the first wire groove bears the second wire net coplanar with the first wire net, a gap exists between the groove bottom of the second wire groove and the first wire net, the radial load of the first wire net on the compression roller set can be reduced during cutting operation, and the service life of the compression roller set is prolonged.

Description

Cutting mechanism, wire saw unit and wire cutting machine Technical Field The utility model relates to the field of wire cutting machines, and particularly provides a cutting mechanism, a wire saw unit and a wire cutting machine. Background The wire cutting technology has the characteristics of high production efficiency, low operation cost, high operation precision and the like, and is widely applied to the cutting production of workpieces such as semiconductors, photovoltaics and the like. Most of the cutting mechanisms in the current wire cutting machines on the market are a three-roller type cutting mechanism and a four-roller type cutting mechanism, and the two cutting mechanisms have the advantages of high precision, high efficiency, wide applicability, good stability, easiness in operation and maintenance and the like. Taking a wire cutting machine with a four-roll cutting mechanism as an example, as shown in fig. 1, the four-roll cutting mechanism 100 is composed of four cutting rolls distributed in a quadrilateral form, however, the cutting lines of four wire webs formed on the four cutting rolls are not on the same plane with each other, if one wire web is designated as a cutting wire web for performing a cutting task, the wire web opposite to the one wire web may interfere with a workpiece to be cut during the cutting operation, thereby leaving an additional trace on the workpiece to be cut different from the cutting trace formed by the cutting wire web. Such interference phenomenon not only limits the height of the workpiece to be cut but also causes an increase in the defective rate of the cut workpiece. In order to solve the above problem of the limited height of the workpiece to be cut, it is generally necessary to press one wire mesh of the cutting roll 11 against the other wire mesh corresponding thereto by using a press roll set 12, as shown in fig. 2 to 3, so that the two wire meshes are arranged coplanar. However, since the press roll set 12 is directly contacted with the two wire webs, the press roll set needs to bear radial loads from the two wire webs at the same time in the cutting operation, and the press roll set is easy to wear, deform and even break after long-time running, which seriously affects the service life of the press roll set. Accordingly, there is a need in the art for a new solution to the above-mentioned problems. Disclosure of utility model In order to solve at least one of the problems of the prior art, namely to solve the problem of how to reduce the radial load borne by the set of rolls while achieving coplanarity of the two webs, the present application provides a cutting mechanism comprising: cutting lines; The cutting roll set is wound with the cutting line and forms a first wire net and a second wire net; The press roll set is located one side of the second wire net away from the first wire net, a first wire groove and a second wire groove which are arranged in a staggered mode are formed in the press roll set, the first wire groove is arranged to enable the second wire net to be pressed towards the first wire net so as to enable the first wire net and the second wire net to be coplanar, the second wire groove corresponds to the first wire net, and the groove depth is larger than that of the first wire groove. The pressing roller group is arranged on one side of the second wire mesh, which is far away from the first wire mesh, and the second wire mesh is pressed towards the first wire mesh under the action of the first wire groove on the pressing roller group, so that the coplanarity of the first wire mesh and the second wire mesh can be realized, the height of a workpiece to be cut is not limited by the distance between the two layers of wire meshes in the existing cutting mechanism, and the applicability and the practicability of the cutting mechanism are improved. In addition, the groove depth of the second wire groove is set to be larger than the groove depth of the first wire groove, so that when the first wire groove bears the second wire net coplanar with the first wire net, a gap exists between the groove bottom of the second wire groove and the first wire net, radial load of the first wire net on the compression roller set can be reduced during cutting operation, and the service life of the compression roller set is prolonged. In the preferable technical scheme of the cutting mechanism, the press roller group comprises a first press roller group and a second press roller group which are arranged at intervals, and the first press roller group and the second press roller group are respectively provided with the first wire slot and the second wire slot. The first press roller group and the second press roller group which are arranged at intervals are adopted to press the second wire mesh to the first wire mesh, so that the coplanar wire mesh between the two press roller groups is beneficial to cutting the workpiece to be cut. In the preferable technical
