Abstract
The utility model relates to a device for improving the edge reject ratio of an NTC 442 slicing machine. The device is characterized by sequentially comprising a base (1), an iron plate (2), glass (3) and a silicon bar (4) from top to bottom. A cushion block (5) is arranged between the base (1) and the iron plate (2) and arranged at the left end of the base (1) and the left end of the iron plate (2). Due to the arrangement of the cushion block, the left side of P1 is inclined downwards, therefore, the wire arch effect can be reduced, the edge reject ratio is eventually reduced, and the yield is improved.
Description
Technical field
The utility model relates to the device of a kind of NTC442 of improvement slicer edge fraction defective.
Background technology
For improving the conversion efficiency of downstream cell piece, the silicon chip cutting changes unidirectional cutting into from Double Directional Cutting, improved the silicon chip surface quality, and after changing unidirectional cutting into, the edge fraction defective of NTC442 slicer obviously rises, as shown in Figure 1, steel wire enters left side and goes out from right side, the mortar of nozzle ejection is followed the steel wire trend and is entered silico briquette and reach cutting effect, but owing to being that unidirectional cutting causes P1 position and P2 position left side can't have enough mortars to bring at present, but at first the line bow produced due to gauze can cut to the P1 right side is the same left side, P2 position, P2 right side and P1 left side are owing to being subject to the line bow to affect more difficult cutting, but the P2 right side has a large amount of mortars to follow steel wire enters the impact that minimizing P2 right side produces because of the line bow, the P1 left side is that occurrence positions is concentrated at current edge thus.Therefore seek a kind of effect that can reduce the line bow, finally reduce the edge fraction defective, the device that can improve NTC442 slicer edge fraction defective that improves yield rate is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of effect that can reduce the line bow is provided, and finally reduces the edge fraction defective, improves the device that can improve NTC442 slicer edge fraction defective of yield rate
The purpose of this utility model is achieved in that
A kind of device that improves NTC442 slicer edge fraction defective, is characterized in that it comprises base, iron plate, glass and silicon rod from top to bottom successively, between described base and iron plate, is provided with cushion block, and described cushion block is arranged at the left end of base and iron plate.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is because cushion block is arranged so that P1 left side is downward-sloping, thereby can reduce the effect of line bow, finally reduces the edge fraction defective, improves yield rate.
The accompanying drawing explanation
Fig. 1 is NTC442 slicer schematic flow sheet.
Fig. 2 is the structural representation that the utility model improves the device of NTC442 slicer edge fraction defective.
Wherein:
Base 1
Iron plate 2
Glass 3
Silicon rod 4
Cushion block 5.
The specific embodiment
Referring to Fig. 2, the device of a kind of NTC442 of improvement slicer edge fraction defective that the utility model relates to, it comprises base 1, iron plate 2, glass 3 and silicon rod 4 from top to bottom successively, be provided with cushion block 5 between described base 1 and iron plate 2, the thickness of described cushion block 5 is 1.5mm, the length of described cushion block 5 is 320mm, and described cushion block 5 is band, iron bar or other objects, and described cushion block 5 is arranged at the left end of base 1 and iron plate 2.
