Fully automatic spacer spraying device system
Abstract
(57) -- the summary -- it is a spacer spraying equipment system used for the spraying process of a spacer in the eye manufacturing process of liquid crystal substrate. Conventionally, since quality was unstable, this process was not able to improve the product yield. The present invention is a full automatic spacer spraying equipment system aiming at automation of discernment in order to solve the problem. Style 成 The spraying machine (1) which formed the insertion machine (3) in the entrance side, and formed the expenditure machine (4) in the exit side, and the spacer counter (2) which prepared NG buffer (5) are connected, A spraying state is automatically inspected for the work sprinkled with the spraying machine (1) with an image processing system at a spacer counter (2), a statistical work is carried out for the data, and the result is carried out to a signal output (6) and a signal output (7), and is taken out. As a result, a signal output (6) is used for automatic adjustment of spraying conditions, and a signal output (7) classifies the quality of a work and it carries out classification storage by NG buffer (5).

Description: TECHNICAL FIELD [Detailed description of the invention]
【0001】
[Industrial application field]
The present invention relates to a system that can be used in the process of manufacturing a liquid crystal substrate.
【0002】
[Conventional technology]
Conventionally, spacer spraying during the manufacturing process of a liquid crystal substrate has been subjected to a sampling inspection with a desktop microscope or the like.
【0003】
[Problems to be Solved by the Invention]
(A) Due to the variety of spacer spraying conditions, it was difficult to control manually. (B) The inspection process could not be inlined. (C) The spraying condition could not be confirmed on time and the spraying conditions could not be adjusted. (D) In the inspection by sampling, it was uneconomical because a large amount of defective products were produced because it was troublesome to complete the spray adjustment after confirming the abnormality. (E) The manufacturing cost was high.
【0004】
[Means to solve the problem]
Connect the spreader (1) with the insertion machine (3) on the entrance side and the dispenser (4) on the outlet side with the spacer counter (2) with the NG buffer (5), and use the spreader (1). The sprayed work is automatically inspected by the image processing system with the spacer counter (2), the data is statistically processed, and the results are signal output (6) and signal output (7). As a result, the signal output (6) is used for automatic adjustment of the spraying conditions, and the signal output (7) is classified and stored by the NG buffer (5) by classifying the quality of the work.
【0005】
[Usage]
Since the spraying conditions of the sprayer (1) are always automatically adjusted by the signal output (6) of the spacer counter (2), a workpiece in which the spacers are uniformly sprayed is always produced. If the spacers are not evenly sprayed, they are sorted and stored in the NG buffer (5) by the signal output (7) from the spacer counter (2).
【0006】
[Example]
Hereinafter, examples of the present invention will be described. (A) The work to be sprayed with the spacer is loaded into the sprayer (1) by the insertion machine (3). (B) Spray the spacer with the sprayer (1). (C) The work is dispensed by the dispenser (4) and loaded into the spacer counter (2). (D) The number of spacers sprayed on the work is counted by the spacer counter (2), and after performing the prescribed statistical processing, the quality of the work is judged and the spraying conditions are set in the sprayer (1) in the previous process. Signal output (6). (E) The workpieces discharged from the spacer counter (2) are classified and stored in the NG buffer (5) according to the contents of the output signal (7). (F) If the spacer counter (2) confirms that the spraying standard has not been passed, the sprayer (1) automatically controls the spraying conditions according to the preset program according to the output signal (6).
【0007】
[Effect of the invention]
By fully automating the spraying work of spacers, it has become possible to standardize the quality of spraying work, which has greatly reduced manufacturing costs by stabilizing product quality and improving yield.
