Abstract

A screen printing device includes a printing work part; a mask storage part including a plurality of accommodating sections each capable of accommodating a screen mask; a transfer device that transfers the screen mask between each of the accommodating sections and the printing work part; a pair of first guide members that is disposed in the printing work part, and guides the screen mask during the transfer, the pair of first guide members having a variable interval; a pair of second guide members that is disposed in the accommodating sections, and guides the screen mask during the transfer; and a guide width determination device that determines whether or not the interval between the pair of first guide members coincides with the interval between the pair of second guide members.

First claim

What is claimed is:

1. A screen printing device comprising:
a printing work part in which printing work is executed;
a mask storage part that is disposed on a side of the printing work part and includes a plurality of accommodating sections each capable of accommodating a screen mask;
a transfer device configured to move the screen mask in a first direction to transfer the screen mask between each of the accommodating sections of the mask storage part, and the printing work part, the first direction being horizontal;
a pair of first guide members that is disposed at an interval in a second direction orthogonal to the first direction in the printing work part, and configured to guide the screen mask during the transfer, the pair of first guide members having a variable interval;
a pair of second guide members that is disposed at an interval in the second direction orthogonal to the first direction in each of the accommodating sections of the mask storage part, and configured to guide the screen mask during the transfer; and
a guide width determination device configured to determine whether or not the interval between the pair of first guide members coincides with the interval between the pair of second guide members before the transfer of the screen mask by the transfer device is started.

2. The screen printing device according to claim 1 , wherein
the guide width determination device includes a sensor comprising a plurality of detecting parts, each of the detecting parts being attached to one side of each of the first guide members and each of the second guide members, and a plurality of detected parts, each of the detected parts being attached to another side of each of the first guide members and each of the second guide members, and in a case where each of the detecting parts has detected each of the detected parts, the guide width determination device determines that the interval between the pair of first guide members coincides with the interval between the pair of second guide members.

3. The screen printing device according to claim 2 , wherein
each of the detecting parts and the detected parts are attached at positions opposed to each other in the first direction in a state where the interval between the pair of first guide members coincides with the interval between the pair of second guide members, and
the detecting parts are configured to detect the detected parts at the positions opposed to the detecting parts in the first direction.

4. The screen printing device according to claim 1 , comprising
a notification device configured to notify a determination when the guide width determination device determines that the interval between the pair of first guide members does not coincide with the interval between the pair of second guide members.

5. The screen printing device according to claim 2 , comprising
a notification device configured to notify a determination when the guide width determination device determines that the interval between the pair of first guide members does not coincide with the interval between the pair of second guide members.

6. The screen printing device according to claim 3 , comprising
a notification device configured to notify a determination when the guide width determination device determines that the interval between the pair of first guide members does not coincide with the interval between the pair of second guide members.
