Description
Technical Field
The utility model relates to a cutting machine, in particular to a multi-shaft multi-station cutting machine, and belongs to the field of cutting machines.
Background

The multi-wire cutting technology of the silicon wafer is an advanced silicon wafer processing technology in the world at present, is different from the traditional cutting modes of a knife saw blade, a grinding wheel blade and the like, is also different from advanced laser cutting and inner circle cutting, and has the principle that a steel wire moving at a high speed drives cutting edge materials attached to the steel wire to rub against a silicon rod, so that the cutting effect is achieved. In the whole process, a steel wire is guided by dozens of guide wheels to form a wire net on a main wire roller, and the workpiece to be processed is fed by lifting the workbench. Compared with other technologies, the multi-wire cutting technology for the silicon wafer comprises the following steps: high efficiency, high productivity, high precision and the like. Is the most widely adopted silicon wafer cutting technology at present. The multi-wire cutting technology is a marked innovation in the silicon processing industry and the solar photovoltaic industry, replaces the original inner circle cutting equipment, and compared with the inner circle slicing technology, the cut wafer has the advantages of small bending degree (BOW), small warping degree (WARP), good parallelism (TAPER), small discreteness of total Thickness Tolerance (TTA), small cutting edge cutting loss, shallow surface damage layer, small surface roughness of the wafer and the like. The linear cutting mechanism of the solar silicon wafer is that a machine guide wheel drives a steel wire in high-speed operation, so that mortar mixed with polyethylene glycol and silicon carbide micro powder is sent to a cutting area by the steel wire, and the steel wire continuously rubs with a workpiece pressed on a wire net in the high-speed operation to finish the cutting process.
The main effects on the quality and yield of silicon wafers during the whole cutting process are the viscosity of the cutting fluid, the particle type and particle size of the silicon carbide micro powder, the viscosity of the mortar, the flow rate of the mortar, the speed of the steel wire, the tension of the steel wire, the feeding speed of the workpiece, and the like.

Based on the current situation of the current domestic photovoltaic industry, the multi-wire cutting machine adapts to the requirements of the current domestic photovoltaic industry with low price, small, exquisite and flexible machine type, real and durable quality.
However, the current multi-wire saw has several fatal drawbacks: if the blank falls off in the cutting process, the blank directly falls on the cutting wire net and is brought into the roller along with the movement of the cutting wire, so that the cutting wire is broken, the machine halt is caused, and the slicing defects and the like are caused.
The novel device is invented and manufactured by breaking diamond wires to generate halt due to the fact that the blanks enter a roller along with a cutting wire net after being collapsed when the neodymium iron boron magnet sheets are cut; the equipment is suitable for small blanks, the cutting direction of the equipment is horizontal multi-wire cutting, and the traditional multi-wire cutting machine is vertical cutting. Most of the traditional multi-wire cutting machines are three-shaft one-station and four-shaft two-station, shafts and rollers cannot correspond to stations one by one, the number of the rollers is more than that of the stations, and the rollers and diamond wires are left vacant, so that the manufacturing cost and the use cost are increased (the shafts refer to the rollers, the rollers comprise the shafts, roller skins and the like; the stations refer to the positions of a workbench, and one workbench is arranged between the two rollers and is a station).

The cutting shaft is vertical, the cutting shaft refers to a roller, and the vertical type is vertically arranged.
Due to the structural characteristics, the machine can be designed into a multi-shaft and multi-station machine type, so that the production efficiency is greatly improved, and an automatic production line is formed;
viscosity of cutting fluid: since the silicon carbide fine powder is suspended on the cutting fluid and cut by the steel wire during the whole cutting process, the cutting fluid mainly plays a role in suspension and cooling. The viscosity of the cutting fluid is an important guarantee for suspending the silicon carbide micro powder. Due to different system thinking of different machine development designs, the viscosity of the mortar is different, namely the viscosity of the cutting fluid is required to be different. The uniform suspension distribution of the silicon carbide micro powder and the stable entering of the mortar into the cutting area along with the steel wire through the mortar pipeline can be ensured only if the viscosity meets the cutting standard required by the machine. Since the steel wire with mortar generates high temperature due to friction during cutting silicon materials, the viscosity of the cutting fluid plays an important role in cooling. If the viscosity does not reach the standard, the fluidity of the cutting fluid is poor, the temperature cannot be reduced to cause burn or broken lines, and therefore the viscosity of the cutting fluid ensures the temperature control of the whole process.
Particle type and particle size of the silicon carbide micro powder: the cutting of the solar silicon wafer is actually that the steel wire carries the silicon carbide micro powder to be cut, so the grain type and the granularity of the micro powder are the key points of the smoothness and the cutting capability of the silicon wafer surface. The laser dicing saw and the grain type are regular, and the cut silicon wafer has good finish; the particle size distribution is uniform, and the cutting capability of the silicon wafer can be improved.
Viscosity of mortar: the strength of the cutting capability of the wire cutting machine on the silicon wafer is inseparable with the viscosity of the mortar. The viscosity of the mortar depends on the viscosity of the cutting fluid of the silicon wafer laser scribing machine, the adaptability of the silicon wafer cutting fluid and the silicon carbide micro powder, the proportion ratio of the silicon wafer cutting fluid to the silicon carbide micro powder, the mortar density and the like. The cutting efficiency and the yield can be improved only when the mortar viscosity (about 250 required by the NTC machine) reaches the machine required standard in the cutting process
Flow rate of mortar: in the high-speed movement of the steel wire, in order to finish the cutting of the silicon material, mortar must be pumped to a sand blasting nozzle from a storage box by a mortar pump and then sprayed onto the steel wire by the sand blasting nozzle. Whether the flow of the mortar is uniform or not and whether the flow can meet the cutting requirement or not play a very key role in the cutting capability and the cutting efficiency. If the flow cannot be followed up, the cutting capability is seriously reduced, and the wire mark sheet, the wire breakage and even the machine alarm are caused.
Speed of the steel wire: because the wire cutting machine can carry out unidirectional wire routing and bidirectional wire routing according to the requirements of users, the requirements on the wire speed under the two conditions are different. When the wire is routed in one direction, the steel wire always keeps running at a speed, so that the control is relatively easy. The operation of the one-way routing is less and less at present. When the wire is routed in two directions, the speed of the steel wire is accelerated to a specified speed in 2-3 seconds from the zero point along one direction, after the steel wire runs for a period of time, the steel wire is slowly reduced to the zero point along the original direction, after the zero point stops for 0.2 seconds, the steel wire is slowly accelerated to the specified speed in the reverse direction, and then the steel wire is slowly reduced to the zero point along the reverse direction. In the process of bidirectional cutting, the cutting capacity of the wire cutting machine is improved along with the increase of the speed of the steel wire in a certain range, but the cutting capacity of the wire cutting machine cannot be lower than or exceed that of mortar. If the cutting capacity of the mortar is lower than that of the mortar, line mark sheets and even broken lines can appear; on the contrary, if the cutting capability of the mortar is exceeded, the mortar flow rate can not be kept up, and thick and thin slices, even line mark slices and the like can occur.
Tension of steel wire: the tension of the steel wire is one of the key elements in the silicon wafer cutting process. Poor tension control is a significant cause of line marking, edge chipping, and even short lines.
The too small tension of the steel wire will result in the increase of the bending of the steel wire, the decrease of the sand carrying capacity and the reduction of the cutting capacity. Thereby causing a line mark chip or the like. The steel wire has excessive tension, so that the silicon carbide micro powder suspended on the steel wire is difficult to enter saw seams, the cutting efficiency is reduced, line mark sheets and the like appear, and the probability of line breakage is high. When the rubber strip is cut, the tension is used for a long time, so that the zero point is deviated, and edge breakage and the like sometimes occur.
Feed rate of workpiece: the feeding speed of the workpiece is related to the speed of the steel wire, the cutting ability of the mortar, the shape of the workpiece at different positions of feeding, and the like. The workpiece feeding speed is determined by the above related factors throughout the cutting process, and is one of the least non-quantitative factors. However, poor control may cause adverse effects such as the occurrence of a line mark sheet, which may affect the cutting quality and yield.
