Description

  The present invention relates to a printing apparatus and a printing method for applying a printing material such as a conductive paste to a substrate or a solar battery cell, for example.

  Conventionally, as a printing method, a printing head is formed by covering a substrate to be printed with a mask in which printing pattern holes are formed, placing a printing head filled with a paste-like printing material on the mask, and extruding the printing material by applying pressure. There is a method of transferring the printing material to the printing material by moving the pattern on the mask and filling the printing pattern holes with the printing material.

However, in the printing material coating apparatus described in Patent Document 1, bubbles may be mixed when the viscous material is filled into the pressure chamber by the viscous material supply means, and air is applied when the viscous material is applied. Since it was applied in a contained state, there was a problem that the coating quality, that is, the printing quality of the printing medium was lowered.
In addition, in order to remove the mixed bubbles, it is necessary to vacuum defoam all the viscous material in the device body and the viscous material supply means, and there is a problem that the defoaming has a long time and the workability is poor. There was also.

  As a printing device that prevents air bubbles from entering the printing material, it includes a press-fitting head that is a printing head and a piston that discharges paste and that can be reciprocated in the press-fitting head. And a sensor, an exhaust port is connected by a pipe to a vacuum pump that exhausts air in the press-fitting head, an injection port is connected by a pipe and a syringe that supplies paste into the press-fitting head, and a sensor is connected in the press-fitting head There is one that detects the paste liquid level (see, for example, Patent Document 2).

A third step of removing the exhaust pipe from the connection pipe, connecting the printing material transfer pipe to the connection pipe, closing the connection pipe valve, and disposing the printing material discharge port of the print head on the mask surface. When,
The pressurizing source is activated, the pressure plate is used to pressurize the membrane member isolation body via the pressing plate, and the printing material is ejected from the printing material ejection port onto the mask to print the printing material. A fourth step of
A fifth step of opening the connection piping valve, operating the printing material transfer means, and filling the printing head with the printing material consumed for the printing,
A printing method comprising performing the first to fifth steps in order. A printing method by the printing apparatus according to claim 1,
A first step of removing the integrated member of the membrane member separator, the connecting pipe, and the pressing plate from the exterior container of the print head;
A second step of connecting the printing material transfer pipe to the connection pipe having the connection pipe valve opened and then operating the printing material transfer means to fill the space in the membrane member isolator with the printing material;
The sealing plate closes the opening of the membrane member separator, connects the exhaust pipe to the connection pipe instead of the print material transfer pipe, operates the exhaust means, and removes the filled printing material. A third step of foaming;
The exhaust pipe is removed from the connection pipe, the sealing plate is removed from the membrane member separator, and the integral member of the membrane member separator, connection pipe and pressing plate filled with the printing material is set in the outer container. And after attaching the printing material discharger to the outer container, a fourth step of arranging the printing material discharge port on the mask surface;
After closing the connection piping valve, the pressure source is operated, the pressure member pressurizes the membrane member separator through the push plate, and the printing material is placed on the mask from the printing material discharge port. A fifth step of discharging and printing the printing material,
A printing method comprising performing the first to fifth steps in order. A printing method by the printing apparatus according to claim 1,
A first step of removing the integral member of the membrane member separator, the connection pipe, and the pressing plate from the exterior container of the print head, and closing the opening of the membrane member separator with a sealing plate;
The exhaust pipe is connected to the connection pipe having the connection pipe valve opened, and the exhaust means is operated to exhaust the air in the membrane member separator, thereby crushing the membrane member separator and closing the connection pipe valve. Two steps;
After connecting a printing material transfer pipe to the connection pipe instead of the exhaust pipe, the connection pipe valve is opened and the printing material transfer means is operated to fill the membrane member isolator with the printing material. 3 steps,
A fourth step of reconnecting the exhaust pipe to the connection pipe instead of the printing material transfer pipe and operating the exhaust means to degas the printing material filled in the membrane member isolator. When,
The exhaust pipe is removed from the connection pipe, the sealing plate is removed from the membrane member separator, and the integral member of the membrane member separator, connection pipe and pressing plate filled with the printing material is set in the outer container. And, after attaching the printing material discharger to the outer container, a fifth step of arranging the printing material discharge port on the surface of the mask;
After closing the connection pipe valve, the pressure source is operated, the pressure member is used to press the film member separator through the pressing plate, and the printing material is placed on the mask from the printing material discharge port. And a sixth step of printing the substrate to be ejected,
A printing method comprising performing the first to sixth steps in order. A printing method using the printing apparatus according to claim 2,
The lid was closed with air so that no air could enter from the printing material discharge port, the printing material transfer pipe was connected to the first connection pipe that opened the first connection pipe valve, and the second connection pipe valve was opened. A first step of connecting the exhaust pipe to the second connection pipe;
After the printing material transfer means is actuated to fill the printing material filling section of the print head with the film member separator and the printing material discharge body, the exhaust material is actuated to activate the printing material in the printing head. A second step of defoaming,
The first connection piping valve and the second connection piping valve are closed, the lid is removed, the printing material discharge port is disposed on the mask surface, and then the pressure source is operated to apply pressure. A plate, pressurizing the membrane member separator via a pressing plate, and discharging the printing material from the printing material discharge port onto the mask to print a printing material;
A fourth step of opening the first connection piping valve, operating the printing material transfer means, and filling the printing head with the printing material consumed by the printing,
A printing method comprising performing the first to fourth steps in order.
