Embodiment

[0074] (drip device)

[0075] Figure 5 It is a schematic perspective view of the dropping device 501 for carrying out the method of this embodiment.

[0076] The dripping device 501 of the present embodiment is equipped with: a plurality of discharge devices 601 that can drop liquid materials; a platform 502 that can place the substrate 101 of the dripped liquid material; 502 is an XYZ driving mechanism 503 that relatively moves in the XYZ direction. In the present embodiment, three discharge devices 601 are provided, but the number of them can be changed according to the size of the substrate 101 or the number of panels 102 , for example, two or less or four or more can be provided.

[0077] The discharge device 601 of the present embodiment is a plunger-type discharge device that moves a plunger that closely contacts the inside of the metering tube and moves back and forth at high speed so that the liquid material is sprayed out from the discharge port.

Abstract

To provide a method, a program and a device for dropping a liquid material by relatively moving a nozzle and a substrate at a fixed speed for increasing a nozzle moving speed and improving productivity. In a method, a plurality of works each of which has a dropping point are arranged on a substrate, a discharge signal is transmitted to a discharge device while relatively moving the nozzle of the discharge device and the substrate at a fixed speed to longitudinally traverse or latitudinally traverse a plurality of times over the works on a linear path, and the liquid material is dropped. In the case where a shortest distance (L0) between the dropping points varies by the linear path, the shortest distance (L0) between the dropping points on one linear path and a time (f0) required for the discharge device to perform one discharge are calculated, and based on a value of L0 / f0, the relative moving speed of the nozzle and the substrate is set for each scanning path. A device for implementing such method is also provided.

Description

technical field [0001] The present invention relates to a method, program and device for dropping liquid materials. More specifically, it relates to the following method, program and device: for a substrate of a plurality of identical panels (also referred to as workpieces) arranged regularly, the The dripping device is moved in parallel in the facing surface of the lower surface, across the non-dropping target area existing between each panel, and the dropping device is moved in a linear path from one end of the substrate to the other end without stopping, while only in the dropping target area. Drop the liquid material. Background technique [0002] Conventionally, in the process of bonding two opposing substrates to form a liquid crystal layer cell therebetween, a method (vacuum injection method) of injecting liquid crystals using a vacuum chamber after bonding the two substrates has been used. [0003] However, for a large panel, it may take more than one day just for t...
