Abstract

The invention discloses an automatic grain discharging machine for P-type and N-type crystal grains of a semiconductor refrigerating sheet. The automatic grain discharging machine comprises structures of an electromotor (7), a frequency converter (10), a bearing assembly (1), a base (9), a eccentric wheel (8), a connecting rod (6), a swinging arm (4), a grain discharging platform (3), and the like; three bar-shaped fixed flanges (5) and one bar-shaped movable flange (2) are arranged at the periphery of the front face of the grain discharging platform (3) so that the grain discharging platform (3) is enclosed into a rectangular recess which is large enough to arrange more than 8 grain discharging dies at one time. grains are screened and discharged by mechanical vibration, wherein the screening rate is up to 90%-95%, thereby greatly improving the grain discharging speed, enhancing production efficiency by more than 8 times, reducing the production cost, and lightening the labor intensity of workers.

Description

technical field

[0001] The invention relates to a semiconductor refrigerating sheet manufacturing equipment, in particular to a semiconductor refrigerating sheet P, N type crystal grain automatic granulator. technical background

[0002] Before the present invention is made, there has not been any report or use of the similar P, N-type crystal grain automatic granulator for semiconductor refrigeration chips at home and abroad.

[0003] Semiconductor refrigeration sheet, also known as thermoelectric refrigeration sheet, is a semiconductor device that uses the inverse effect of semiconductor thermoelectricity to achieve the purpose of cooling (or heating). A galvanic pair (see attached for schematic Figure 4 ), when the DC current flows from the N pole to the P pole, an endothermic phenomenon occurs on the A terminal, this terminal is called the cold terminal, and the lower B and C terminals generate heat release, this terminal is called the hot terminal, if the current direc...
