Description
Technical field
The present invention relates to the field of silicon rod cutting, the height-adjustable silicon rod positioner of especially a kind of combined type.
Background technology
In manufacture of solar cells process, by silicon rod on request length to be cut into pieces be the first operation of silicon chip cutting processing, at present, the silicon rod section of cutting fixture used is vertical pair of V-arrangement positioning clamping, it was carried out location to silicon rod respectively by two vee-block synchronous clamping mechanisms of three lineal layouts and clamped, every secondary vee-block clamp mechanism is carried out tense-lax by opposed two vee-blocks in front and back by the left and right screw rod mode of tightening up, in every secondary vee-block clamp mechanism, there are two anchor points to contact with silicon rod, its advantage shows: after silicon rod location clamps, even the diameter of silicon rod, circularity, cylindricity has the axis height that error can not change silicon rod two ends, the axis of silicon rod is parallel with horizontal plane, after cutting, the axis verticality of two ends and silicon rod is good.But it is typically to cross location structure, but the system rigidity of this three secondary vertical pair of vee-block clamp mechanism is poor, if Cutting Drag is excessive, silicon rod can produce shake, makes cut surface produce difference of height, directly affects flatness; Vertical pair of V-arrangement positioning clamping, when cutting to end, fixture must be unclamped, after must manually making silicon rod reverse end for end to install on fixture, can cut, in this process, both need a dead lift and tune, need again to reinstall and clamp, because silicon rod is not only sliding but also dirty, very easily landing injures operator, and not only labour intensity is large, and complex operation, work efficiency is low, has potential safety hazard.
The deficiency existing in order to overcome vertical pair of V-arrangement positioning clamping, in the market, occurred " a kind of silicon rod cutting machine special fixture of adjustable head ", it is a kind of Horizontal type dual-V-shaped piece positioning clamping, comprise two positioning clampings that formed by V-arrangement positioning seat and synchronous clamping mechanism that distribute along silicon rod axially spaced-apart, whole positioning and clamping mechanism rotates around the center line of two V-arrangement positioning seats simultaneously, the synchronous clamping mechanism of this fixture can synchronously clamp and unclamp silicon rod, silicon rod is placed on horizontally disposed pair of V-arrangement positioning seat, movable clamping head is pressed in the top of silicon rod symmetrically, improved the system stiffness of whole fixture, eliminated the silicon rod jitter phenomenon in cutting process, the flatness of silicon rod cutting end face can guarantee.Owing to having set up rotating mechanism between base and V-arrangement positioning seat, V-arrangement positioning seat can rotate with respect to base, and it can meet silicon rod cutting machine technological requirement to the whole tune of clamp body in cutting process.Location locking mechanism can guarantee that silicon rod often turns over 180 ° and just automatically locates, then by retaining mechanism, locked, it can meet 180 ° of tunes of needs in silicon rod cutting process, accurately location and the technological requirement of fixing and locking well, both alleviate labor intensity of operating staff, improved again production security and efficiency.Although this silicon rod cutting jig has above-mentioned advantage, but also there is between two cutting end faces and silicon rod axis out of plumb, two cutting end faces the defects such as flatness not parallel, same end face is not up to standard in actual use procedure, because the silicon rod cylindricity drawing out from crystal pulling furnace is not high, always there is concentric reducer phenomenon in silicon rod two ends, when silicon rod is shelved on horizontal two V-arrangement positioning seats, the axis of silicon rod and horizontal plane certainly exist certain angle, the perpendicularity of cutting rear end face and silicon rod axis is bad, and this is in silicon rod segment operation, to be reluctant the major defect of appearance most.
In recent years, photovoltaic is developed rapidly as clean renewable green energy resource, many developed countries and developing country all formulate the incentive policy of exploitation, promotion and application photovoltaic, encourage solar energy production enterprise to carry out research and the industry of low-cost solar battery component technology, make this regenerative resource of solar energy be able to extensive use.
At present, people know solar energy power generating and have plurality of advantages than conventional thermal power generation, but because the production cost of solar components will be far above the cost of thermoelectricity generating, serious have affected applying of photovoltaic.Countries in the world are all wanted to greatly develop, have many countries all to solar photoelectric industry and application enterprise implement new forms of energy subsidy policys, although can promote from policy aspect the development of photovoltaic industry, but solar module production cost is too high, it is the basic factor of restriction photovoltaic industry development, how further to reduce the production cost of solar module, it is the common focus of paying close attention to of the raw enterprise of domestic and international solar module, Ye Shi photovoltaic enterprise prior art difficult point, the especially inevitable requirement of whole industry development.
At present, the factor that affects solar module production cost is a lot, at the links that draws crystal bar, silicon rod segment, silicon rod butt, square stock section, cell piece production and battery component assembling, all can exert an influence to the cost of end product, wherein, the segment of silicon rod, butt directly have influence on silicon material utilization rate and processing charges, therefore very large on the impact of battery component cost.
Through the fixture technology analysis to existing silicon rod segment and butt, according to traditional cutting technique and technological equipment, between the perpendicularity of the silicon rod section obtaining and the both ends of the surface of silicon rod square stock and silicon rod axis, both ends of the surface, the flatness of the depth of parallelism and end face is all difficult to reach designing requirement, like this, not only have influence on the utilization rate of silicon rod, but also increased cross grinding difficulty and grinding time, border measuring and calculating factually, if above-mentioned defect appears in silicon rod, enterprise reaches 15.5 yuan/root because of man-hour and the labour cost accumulative total that silicon material waste, grinding increase.At present, each enterprise can only lean on the personnel that technical quality is high to operate, even so, the defect rate that Gai workshop section produces is up to 6%～8%, through technical staff's observation, analysis and research, we think how to guarantee that the correct clamping of silicon rod is the emphasis that reduces this workshop section's defect rate, through measuring and calculating, the defect rate of Ruo Jiangben workshop section is down to below 1%, and annual enterprise can synergy more than 2,000 ten thousand yuan.
