Abstract
A finely-divided powder spray apparatus of the invention comprises a spray nozzle pipe disposed at a position spaced apart from a member to be sprayed a prescribed interval; a support unit of the spray nozzle pipe for supporting it so that it can be inclined; a first joint unit disposed to the upper end of the spray nozzle pipe; two linearly-moving actuators that each move in respective linear paths that are fixed relative to each other and each provided with a second joint unit; and two rods for coupling each of the second joint units with the first joint unit; wherein the finely-divided powder is sprayed onto the member to be sprayed from the spray nozzle pipe which is inclined in an arbitrary direction by combining the movements of the two linearly-moving actuators. This spray apparatus is a smaller apparatus capable of spraying the finely-divided powder such as liquid crystal spacers onto a larger member to be sprayed such as a larger glass substrate and does not uselessly spray finely-divided powder to the periphery of a member to be sprayed by providing a drive mechanism for driving a spray nozzle pipe which has a larger spray angle, can move in a prescribed direction at a high speed, applies a uniform load on drive sources for driving the spray nozzle pipe and can change the center of the locus of a spray path along which the finely-divided powder is sprayed and the moving speed of the center of the locus.
