Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as figure 1 , 2 , 3, 4, and 5, a grain screening device includes a grain arrangement mold 1, the grain arrangement mold has an array of grain placement holes 2, and the placement holes cooperate with the arranged grains; There is a vibration device 3 below the grain arrangement mold, and the vibration device is formed by installing an eccentric wheel 5 on the motor shaft head by a motor 4. It is characterized in that: there is also a vibration device between the vibration device and the grain arrangement mold. A rotating device 6, said rotating device can make the crystal grain arrangement mold rotate 360 ​​degrees horizontally.

[0021] The rotating device is a motor that can rotate the grain arrangement mold.

[0022] When the device of the present invention is in use, the crystal grains are tilted to the left and right on the grain arrangement mold, and al...

Abstract

The invention relates to equipment in the technical field of semiconductor refrigeration parts processing. The name is a grain screening device, which includes a grain arrangement mold, and the grain arrangement mold has an array of grain placement holes, the placement holes and the arranged grains. Coordination; there is a vibration device under the grain arrangement mold, the vibration device is formed by a motor and an eccentric wheel installed on the motor shaft head, it is characterized in that: the vibration device and the grain arrangement mold There is also a rotating device in between, and the rotating device can make the grain arrangement mold rotate 360 ​​degrees horizontally, and the upper edge of the grain placement hole has a circular chamfering structure. Such a grain sieving device has the advantages of being able to facilitate the return of the grains used, improving production efficiency, and being convenient to use.

Description

technical field [0001] The invention relates to equipment in the technical field of semiconductor refrigeration parts processing, in particular to a grain screening device. Background technique [0002] Semiconductor refrigeration parts are formed by welding a number of neatly arranged crystal grains on a porcelain plate. [0003] The crystal grains have a quadrangular prism structure; first, the grains need to be arranged neatly on the porcelain plate, and the tool for making the grains neatly arranged is the crystal grain arrangement mold, which has an array of grain placement holes on the grain arrangement mold. Holes and grains cooperate. When in use, place multiple grains on the grain arrangement mold, shake the mold, and the grains will fall into the grain placement holes, and the grains will be arranged neatly. [0004] In order to improve productivity and reduce labor intensity, a vibrating device is arranged under the grain arrangement mold to become a grain screen...
