Abstract
The utility model relates to auxiliary equipment of a single crystal furnace, in particular to a molybdenum seed crystal gripper for a single crystal furnace. The molybdenum seed crystal gripper for the single crystal furnace is formed by combining an upper gripping head (5) with a lower gripping head (6). The body of the upper gripping head (5) is of a cylinder structure of which the upper end and the lower end are provided with frustums, the upper end of the body of the upper gripping head (5) is provided with a bolt I (7) being in threaded combination with a molybdenum hammer, and the lower end is provided with a bolt II (8). The body of the lower gripping head (6) is of a cylinder structure of which two ends are provided with frustums, and the upper end surface of the body of the lower gripping head is provided with a threaded hole being in threaded combination with the bolt II (8) on the upper gripping head. A blind hole (10) used for placing a molybdenum seed crystal (4) is arranged in the body of the lower gripping head, and one side of the lower end of the body of the lower gripping head is provided with a positioning pin (9) for fixing the molybdenum seed crystal. The molybdenum seed crystal gripper is formed by combining the upper gripping head with the lower gripping head, so that the abraded lower gripping head can be conveniently replaced, and the upper gripping head can be recycled. Thus, the cost is saved, and the service life of the molybdenum seed crystal gripper is prolonged.
Description
Technical field
The utility model relates to the utility appliance of single crystal growing furnace, mainly proposes a kind of single crystal growing furnace with molybdenum seed body clamper.
Background technology
Single crystal growing furnace is a kind of in inert gas environment, with graphite heater with various polycrystalline silicon material fusions, with the equipment of Grown by CZ Method dislocation-free monocrystalline.
Silicon single crystal has the crystal of complete basically lattice structure.Different directions has different character, is a kind of good material of partly leading.Purity requirement reaches 99.9999
%, even reach 99.9999999
%More than.Be used for producing the semiconductor devices, solar cell etc.
The molybdenum seed body clamping device of single crystal growing furnace plays an important role aborning, mainly is made up of tungsten filament rope 1, molybdenum weight 2, molybdenum seed body clamper 3, molybdenum seed crystal, molybdenum seed body 4, and is as shown in Figure 1.Tungsten filament rope 1 is connected with the top of molybdenum weight 2, and the bottom of molybdenum weight 2 is connected with the screw top of molybdenum seed body clamper 3, in molybdenum seed body clamper 3, has molybdenum seed body 4.
The most one-piece constructions that adopt of present molybdenum seed body clamper, as shown in Figure 2, said molybdenum seed body clamper 3 right cylinders by two sections different diameters constitute; Wherein the less right cylinder of diameter is positioned at the top of diameter than large cylinder, and upper cylinder has the outside screw that is threaded in order to the molybdenum weight; Said diameter has frustum than the two ends of large cylinder; In the bigger right cylinder of diameter, have the blind hole that is used to be provided with the molybdenum seed body, and have dowel hole on the bigger right cylinder of diameter, be used for through the fixing molybdenum seed body of steady brace.Because the clamping process at the molybdenum seed body often produces wearing and tearing, because molybdenum seed body clamper is an one-piece construction, need all more change molybdenum seed body clamper during replacing, cause waste, and replacement cost is higher.
The utility model content
For overcoming the above problems, the purpose of the utility model is to propose a kind of single crystal growing furnace with molybdenum seed body clamper.
The utility model adopts following technical scheme for accomplishing the foregoing invention task:
A kind of single crystal growing furnace is with molybdenum seed body clamper, and described molybdenum seed body clamper is an integrated structure, is constituted by upper grip, lower chuck two portions; Said upper grip has the cylindrical structure of frustum for two ends up and down, and the upper end of upper grip has and molybdenum weight screw thread bonded bolt I, and the lower end has and lower chuck screw thread bonded bolt II; Said lower chuck has the cylindrical structure of frustum for two ends up and down, the upper surface of lower chuck have with upper grip on bolt II screw thread bonded threaded hole; Lower chuck has the blind hole that is used to be provided with the molybdenum seed body, and the side in the lower chuck lower end has the steady brace that is used for fixing the molybdenum seed body.
A kind of single crystal growing furnace that the utility model proposes is with molybdenum seed body clamper; Adopt upper grip to combine the integrated structure that constitutes with lower chuck two portions screw thread; After the lower chuck wearing and tearing, can replacing be backed out in its rotation, and upper grip can be recycled; Both provided cost savings, improved the work-ing life of molybdenum seed body clamper again.
