Abstract
The invention provides a silicon rod bonding device with an adjustable cutting deflection angle. The silicon rod bonding device comprises an adjustable dovetail seat, an adjustable supporting plate and adjusting bolts. The two sides of the adjustable dovetail seat are provided with right-hand thread holes. Left-hand thread holes are formed in the positions, corresponding to the right-hand thread holes of the adjustable dovetail seat, on the adjustable supporting plate. The hole diameter of the right-hand thread holes is larger than that of the left-hand thread holes. The upper segments of adjusting bolts are right-hand threads and matched with the right-hand thread holes in the adjustable dovetail seat. The length of the right-hand thread segments of the adjusting bolts is larger than that of the right-hand thread holes in the adjustable dovetail seat. The lower segments of the adjusting bolts are left-hand threads and matched with the left-hand thread holes in the adjustable supporting plate. The length of the left-hand threads of the adjusting bolts is equal to that of the left-hand thread holes in the adjustable supporting plate. The adjusting bolts penetrate through the right-hand thread holes and the left-hand thread holes to fixedly connect the supporting plate to the dovetail seat. By means of the silicon rod bonding device with the adjustable cutting deflection angle, the problem of deflection angle cutting of a silicone rod to be cut is solved, repeated loading and unloading caused by mounting error are avoided, and labor intensity is lowered.
Description
Technical field:
The present invention relates to a kind of multi-wire saw cutting silicon rod adhering device, particularly relate to the multi-wire saw cutting silicon rod adhering device of adjustable-angle.
Background technology:
Solar energy is green regenerative energy sources, and in effective utilization of solar energy, solar photovoltaic utilization is the research field that development in recent years is fast, the most most active.Along with solar cell in recent years develop rapidly with constantly apply, market is increasing for the demand of solar cell.Crystal silicon solar energy battery is more and more applied to energy field, and wherein, silicon materials are main carriers of solar photovoltaic utilization, and the preparation of crystalline silicon is the basis of photovoltaic cell.
In silicon chip working process, silicon rod slicing is one critical process.In traditional handicraft, silicon rod is cut into the method for multi-disc silicon chip, multi-wire saw is through two pieces of silicon rods of chamfered simultaneously, central shaft and the central shaft of second piece of silicon rod of first piece of silicon rod are parallel distribution, first piece of silicon rod and second piece of silicon rod complete and plane-parallel when fixing, and line of cut is parallel with the bottom of silicon ingot, does not have inclination angle.During the cutting of tradition silicon rod cutting device as shown in Figure 1, multi-wire saw silicon rod adhering device comprises dovetail seat 1 and supporting plate 2, and supporting plate 2 is fixedly connected on dovetail seat 1; The glass plate 3 being bonded with silicon rod 4 to be cut is fixedly bonded on supporting plate 2 by iron plate glue, the dovetail seat 1 installing silicon rod 4 to be cut is inserted in slicer, line of cut 5 is provided with below silicon rod 4 to be cut, line of cut 5 is wrapped on two guide rollers 6, distance between two guide rollers 6 is greater than the distance outside two silicon rods 4 to be cut, and mortar pipe 7 is distributed in the top of line of cut 5, in slicing processes, mortar flows out from mortar pipe 7, utilizes line of cut 5 to drive mortar to carry out cutting operation.Because the tension force of line of cut 5 is unbalanced, Linear cut movement locus is arc and non-rectilinear; At the end of cutting is fast, easily because the phenomenon that depth of cut is uneven appears in the bending of line of cut 5, cause silicon chip edge appearance defect in various degree, as collapsed limit, the serious limit that collapses is waste product.In order to address this problem, existing multi-wire saw silicon rod adhering device as shown in Figure 2, comprises dovetail seat 1, supporting plate 2 and pad 8, and supporting plate 2 is fixedly connected on dovetail seat 1, between dovetail seat 1 and supporting plate 2 side joint face, be provided with pad 8, lower surface and the horizontal plane of supporting plate 2 have angle.During use, the glass plate 3 being bonded with silicon rod 4 to be cut is fixedly bonded on supporting plate 2 by iron plate glue, the dovetail seat 1 installing silicon rod 4 to be cut is inserted on slicer, by staggered relatively for the side being provided with pad 8, bottom face and the line of cut 5 of silicon rod 4 to be cut have angle, and the bottom in the relative inner face of two silicon rods 4 to be cut is lower than the bottom of two silicon rod 4 lateral surfaces to be cut.Use this inclination angle cutting mode, make the balancing tension of line of cut, ensure the cut quality of silicon chip.But, this arrange between dovetail seat 1 and supporting plate 2 side joint face pad 8 change the method for cutting angle can not regulating cutting angle, need just to need different pads 8 during translation-angle, and set up pad 8 in side, need staggered relatively for two sides setting up pad 8 during installation, placing wrong words just needs to unload to reinstall, loading and unloading all needs staff's manual operation, silicon rod is very heavy, and handling add labour intensity again, very inconvenient.
Summary of the invention:
The invention provides a kind of silicon rod adhering device of adjustable cutting drift angle, the angle of silicon rod cutting position can be adjusted arbitrarily, make Si wafer quality affect minimum at cutting process by line of cut tension force, not only ensure Si wafer quality, and reduce labour intensity.
The technical solution adopted in the present invention is:
A kind of silicon rod adhering device of adjustable cutting drift angle, it is characterized in that: comprise adjustable dovetail seat, adjustable supporting plate and adjustment screw, plus thread hole is had in the both sides of adjustable dovetail seat, on adjustable supporting plate, the position in the plus thread hole of corresponding adjustable dovetail seat has left-hand thread hole, the aperture in plus thread hole is greater than the aperture in left-hand thread hole, the epimere of adjustment screw is plus thread and matches with plus thread hole on adjustable dovetail seat, plus thread segment length in adjustment screw is greater than the length in plus thread hole on adjustable dovetail seat, the hypomere of adjustment screw is left-hand thread and matches with left-hand thread hole on adjustable supporting plate, in adjustment screw, left-hand thread length is equal with the length in left-hand thread hole on adjustable supporting plate, adjustable supporting plate is fixedly connected on adjustable dovetail seat through plus thread hole and left-hand thread hole by adjustment screw.
Owing to having plus thread hole in the both sides of adjustable dovetail seat, on adjustable supporting plate, the position in the plus thread hole of corresponding adjustable dovetail seat has left-hand thread hole, adjustable supporting plate is fixedly connected on adjustable dovetail seat by adjustment screw, and adjustment adjustment screw can change the distance between adjustable dovetail seat and adjustable supporting plate.So just can regulate arbitrarily the cutting angle of silicon rod to be cut, without the need to changing pad, and no matter how adjustable dovetail seat is inserted on cutting machine, can regulate the adjustment screw of opposite flank make silicon rod to be cut oppositely facing having a down dip.Not only solve the inclination angle cutting problem of silicon rod to be cut, and avoid because setup error cause repeat handling, decrease labour intensity.
