Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of diamond wire cutting equipment, in particular to a horizontal wire cutting equipment. BACKGROUND

[0002] The cutting principle of the diamond wire cutting machine is similar to that of the bow saw. The wire reel rotates at high speed and reciprocates to drive the diamond wire to reciprocate, so that the relative grinding motion is formed between the diamond wire and the cutting object, thereby achieving the purpose of cutting. Multi-wire cutting technology is a relatively advanced silicon wafer processing technology in the world. Its principle is to rub the cutting blade attached to the steel wire through a high-speed moving steel wire to cut hard and brittle materials such as semiconductors. In the whole process, the gold wire is guided through multiple guide wheels to form a wire net on the main line roller. Compared with other technologies, multi-wire cutting technology has the advantages of high efficiency, high productivity and high precision. However, the conventional diamond wire cutting device has obvious defects. During diamond wire cutting, cutting waste falls and causes wire breakage; the wire winding wheel replacement process is complex, and the wire winding mechanism needs to be disassembled during replacement, which greatly wastes time.

[0003] The wire winding wheel is an important part of the wire cutting machine tool. The wire winding wheel changes the direction of the gold wire. A general mouth-shaped wire cutting head is composed of four pairs of wire winding wheel mechanisms. In the production process, the gold wire frequently contacts the wire winding wheel, which is easy to wear out and needs to be replaced after a period of use, and also increases the consumption of cutting steel wire. The existing wire winding wheel installation method is generally installed on the same driving shaft. When maintaining and replacing, all parts on the wire winding wheel mechanism need to be disassembled for replacement, which is difficult to disassemble and maintain, greatly increasing the production cost.

[0004] The existing three-net horizontal strip cutting machine has the problem that the gold wire needs to pass through the backshaped wheel frame when threading, which makes it difficult to wind the wire.

[0005] After a long period of use, the wire groove on the roller wheel will be worn, affecting the cutting precision. When the wire groove slot of the roller wheel needs to be replaced, the moving distance of the roller wheel needs to be calibrated, and the moving distance is usually measured and determined by the operator manually, which is not only low in efficiency, but also has the risk of mechanical injury in operation.

[0006] During the last change of the wire cutting, the crystal bar will appear a slight droop phenomenon due to its own gravity and fewer supporting points, which directly affects the straightness of the product cutting. Therefore, there is an urgent need for a crystal bar tail end supporting mechanism for a cutting machine, which can correct the slight droop problem of the crystal bar according to the actual cutting situation.

[0007] In the diamond wire cutting device, the winding and winding process of the diamond wire is a difficulty that restricts the working efficiency of the wire cutting device. If the winding on the winding and winding mechanism is not good, it will cause the tension of the diamond wire to fluctuate unstably during high-speed cutting, and even cause the wire to break, which not only affects the cutting accuracy, but also wastes a lot of manpower, material resources and time.

[0008] Based on the above situation, the present application provides a horizontal wire cutting equipment which can effectively solve the above problems. SUMMARY

[0009] The present application aims to provide a horizontal wire cutting equipment. The horizontal wire cutting equipment of the present application is simple in structure and easy to use. The crystal bar supporting mechanism can accurately position and fix the crystal bar to be cut, ensuring the accuracy of cutting. The anti-cutting edge skin falling device is arranged on the bottom part of the wire cutting structure of the split winding wheel mechanism, which prevents the edge skin from falling and hitting the diamond wire during cutting, causing the wire to break, improves the stability of the equipment during operation, and improves the working efficiency. The slot correction mechanism is arranged on the cutting head, the slot changing operation is simple and the slot changing positioning accuracy is high, which improves the working efficiency and reduces the risk of mechanical injury. The split winding wheel mechanism is installed by end face teeth, which is convenient to install and light in weight. The split roller wheel is composed of two groups of roller wheels with opposite rotating directions, which can offset the cutting chip force during cutting of the crystal bar, thereby minimizing the vibration of the processed object. The crystal bar supporting mechanism, the wire cutting structure and the winding tensioning mechanism are electrically connected with the integrated control box, so that the horizontal wire cutting equipment of the present application has high cutting efficiency and high cutting precision, improves the crystal bar cutting and forming processing efficiency, and reduces the labor intensity of workers.
