The invention relates to a sorting device of heavy-doped silicon materials. The device is composed of a insulated sorting plate, connection lines and a resistivity tester. A plurality of groups of conductive wires with positive and negative poles in turns is arranged on the insulated sorting plate. The plurality of groups of conductive wires with positive and negative poles in turns is connected with the resistivity tester through the connection lines. The sorting device can realize heavy-doped sorting of batches of silicon materials, can raise the sorting efficiency, can sort silicon materials of fine particles, and is beneficial to raise the recovery rate of silicon materials.
Description
Technical field
The present invention relates to a kind of sorting unit of heavily doped silicon material.
Background technology
At present, in the silicon electron trade, often need to carry out sorting to the silicon material, distinguish heavily doped and non-heavily doped silicon material.Common sorting way is to adopt the special tweezers be connected with resistivity tester, by tweezers, clamps the silicon material, judge whether it conducts electricity, and sub-elects heavily doped silicon material.There is following defect in the method: the one, and inefficiency, complete the sorting of heavily doped silicon material, need to clamp judgement to each piece silicon material; The 2nd, for the silicon material sorting of fine particle, owing to being difficult to clamping, just be difficult to sorting.
Summary of the invention
The purpose of this invention is to provide and can improve the efficiency of separation, the sorting unit of a kind of heavily doped silicon material of the recovery utilization rate of raising silicon material.
The technical scheme that the present invention takes is: a kind of sorting unit of heavily doped silicon material, sorting plate, connection line, resistivity tester by insulation form, it is characterized in that being provided with the conductive electric wire of some groups of alternate positive and negatives on the sorting plate surface of insulation, the conductive electric wire electric wire of some groups of alternate positive and negatives all is connected with resistivity tester by connection line.
Adopt the present invention, can carry out heavily doped sorting to silicon material in batch, can improve the efficiency of separation, also can carry out sorting to the silicon material of fine particle, be conducive to improve the rate of recovery of silicon material simultaneously.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure, sequence number means: conductive electric wire positive pole 1, conductive electric wire negative pole 2, sorting plate 3, resistivity tester 4 and connection line 5.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Sorting unit with reference to Fig. 1, this heavily doped silicon material is comprised of the sorting plate 3, connection line 5, the resistivity tester 4 that insulate, be provided with the circuit distance of the conductive electric wire anodal 1 of some groups of alternate positive and negatives and the general conductive electric wire of conductive electric wire negative pole 2(anodal 1 and conductive electric wire negative pole 2 in the 1mm left and right on sorting plate 3 surfaces of insulation), the conductive electric wire of some groups of alternate positive and negatives anodal 1 all is connected with resistivity tester 4 by connection line 5 with conductive electric wire negative pole 2.
While using this device, sorting plate 3 is placed on the desktop of front, the silicon material is laid on sorting plate 3, living the silicon material with the have gentle hands flicking streaks toward the position of front, hear that resistivity tester 4 has " beep " acoustic alarm or the indicator lamp of resistivity tester 4 lights, in the silicon material pinned of explanation, heavily doped silicon material is arranged, then, then carry out sorting at the silicon material of pinning among a small circle.Generally, most of silicon material can there is no " beep " acoustic alarm or the indicator lamp of resistivity tester 4 lights, and these silicon material are non-heavily doped material, can soon it be put under in non-heavily doped material sorting basket.Like this, just can realize the heavily doped sorting of silicon material in batches, can improve the efficiency of separation, also can carry out sorting to the silicon material of fine particle, be conducive to improve the rate of recovery of silicon material simultaneously.
