Embodiment Construction

[0039] FIG. 1 shows the configuration of each device of the solder paste printing system of the present invention.

[0040] As a representative example of the printing system of the present invention, in addition to the screen printing unit 200, its configuration also includes an inspection unit 300 for inspecting the results printed on the screen printing unit (hereinafter referred to as printing unit) 200, and depending on the situation, In case the inspection unit 300 detects a poorly printed but repairable printing state, a plurality of dispenser units 400 are used to repair it.

[0041] Conventionally, in the case of applying solder paste, the solder paste to be applied is supplied to the mask surface in the printing unit 200, and after the preparation is completed, after the position of the mark is pointed and recognized, automatic operation is started, and printing After soldering the paste, the substrate is transferred to the downstream device. In this regard, as in t...

Abstract

The present invention provides a silk screen printing device and printing system comprising the same. In the soldering paste printing system provided with the silk screen printing device, the printing precision of the silk screen printing device is obtained, at the same time the disfigurement which can be repaired in the system is repaired in the system if printing disfigurement occurs in the silk screen printing device, and the product productivity is improved. Therefore, the squeegee used in the printing process of the silk screen printing device is made to a structure using a metal squeegee having two stages of elasticity, and is to a structure of a detecting unit configured to detect the printing state after the printing process is finished and a dispenser unit used for repairing the disfigurement of the printing substrate according to the detecting results; and a system in which the detecting results are transmitted to the silk screen printing device and responded in the printing process of the next substrate is adopted.

Description

technical field [0001] The present invention relates to a screen printing device, and more particularly to a printing device for printing solder paste and a printing system using the same. Background technique [0002] As a conventional screen printing machine, there is a device disclosed in JP-A-5-200975. The screen printing machine has: a stage portion with a substrate carrying in conveyor, a substrate carrying out conveyor, and a lifting mechanism; a mask having a transfer pattern as an opening; a squeegee, a squeegee lifting mechanism, and a horizontal direction. Applicator heads for moving mechanisms; controls for controlling these mechanisms. After placing the substrate loaded into the device on the stage, raise the stage part to bring the substrate close to the mask, and fill the opening of the mask with milky solder or the like while touching the mask to the substrate with a squeegee. The paste is further lowered by lowering the stage portion to separate the substr...
