Rotating needle type microsphere coating manufacturing device

Abstract

The invention provides a rotating needle type microsphere coating manufacturing device. The device comprises a microsphere disc, a rotating needle, a fixed component I, a stepping motor, a prismatic convex block and a fixed component II. The microsphere disc is fixedly connected to the stepping motor through the fixed component II, and a shaft of the stepping motor penetrates through the center of the microsphere disc to be fixedly connected with the rotating needle through the fixed component I. The microsphere disc is fixed, the rotary shaft of the stepping motor drives the rotating needle to rotate, meanwhile, a microsphere in the microsphere disc is shifted to prevent the microsphere from being attached to the microsphere disc, and therefore the microsphere is made to always do irregular motion in the coating and plating process. The rotating needle has certain elasticity, the rotating needle slightly collides with the prismatic convex block and passes through the prismatic convex block in the rotating process, meanwhile, the rotating needle can generate oscillation, and therefore the microsphere is separated from the rotating needle. The device is simple in structure, wide in material source and low in manufacturing cost, the microsphere can be effectively prevented from being attached to the microsphere disc, and the aim of evenly coating and plating the microsphere coating is achieved.

Description

technical field [0001] The invention belongs to the technical field of preparation of microsphere surface coating materials, and in particular relates to a device for preparing a uniform coating on the surface of microspheres. Background technique [0002] In scientific research and production activities, it is necessary to prepare various uniform coatings on the surface of microspheres. For example, in ICF (inertial confinement fusion) physical experiments, it is necessary to prepare various metal and non-metallic uniform coating materials on the surface of microspheres to achieve purpose of scientific research. Although the Chinese patents named "Inclined Microsphere Rolling Device" (Patent No. ZL200920317474.3) and "Microsphere Coating Oscillating Device" (Patent No. ZL200720078394.8) can realize the preparation of uniform coating on the surface of microspheres, they cannot solve the problem. The microspheres are easy to adhere to the microsphere disk, which leads to the...
