A printing device includes a coating material scooping unit configured to scoop a coating material on a mask, and a controller configured or programmed to determine whether or not the coating material scooping unit performs collecting operation to collect the coating material on the mask when the mask is replaced.

Printing device

In a printing device, a second storage position is displaced from a first storage position so as to enable a moving member to move a second mask arranged in a second storage in a state in which a first mask is arranged in the first storage position by movement of the first mask from an operation position to the first storage position by the moving member.

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.

Screen printing device

A printing device includes a controller configured or programmed to acquire, based on a width of a coating material that has been measured, at least one of a start position, an end position, or an amount of movement of a coating material scooping unit in coating material scooping operation.

A substrate working device includes: a base; a first substrate working table and a second substrate working table movably supported on the base; an indicator provided to one of a base side member, which is formed on the base or a member fixed to the base, and the first and second substrate working tables; an imaging unit provided on the other one, which is different from the one, of the base side member and the first and second substrate working tables in order to image the indicator; and a control unit that, by causing the imaging unit to image the indicator and based on image data thereof, acquires position information related to each of the substrate working tables and that moreover determines whether or not the respective substrate working tables interfere with each other at the time of movement of each substrate working table based on the position information.

Substrate working device

A board printing apparatus includes a board working table, a first printing table, a second printing table, and a control portion controlling printing operations. The control portion is configured to perform second printing on a board held by the board working table by a large component mask of the second printing table after a first printing performed on the board held by the board working table by a small component mask of the first printing table.

Board printing apparatus and board printing method

Provided is a solder supply method of supplying, onto a mask sheet, solder to be printed on a printed circuit board. The method includes calculating an amount of solder supplied for a plurality of points in an X direction that is a lengthwise direction of a squeegee, and changing the amount of solder supplied at each point in the X direction based on a result of the calculation.

Method of supplying solder to printed circuit board

An inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. A pair of substrate supporting tables juxtaposed in a specific direction is provided. Screen printing is alternately performed by a single print executing section in a common area which can be shared by the two substrate supporting tables. In doing so, when one substrate supporting table located at a print position among the pair of substrate supporting tables starts exiting the print position, the other substrate supporting table starts entry to the print position.

Screen printing machine

Disclosed is an inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. The screen printing machine comprises a pair of substrate supporting tables provided to hold a respective substrate that is a print object and which is juxtaposed in a direction that is perpendicular to a conveying direction of the substrate, and a print executing section that performs a printing process alternately on the substrate held by the pair of substrate supporting tables. Due to the print executing section being driven in the direction under control of a control unit, a print position where the substrate supporting tables execute alternate printing is changed within a range in which one of the pair of substrate supporting tables and the other of the pair of substrate supporting tables oppose each other in the direction.

A screen printing apparatus is provided with a control unit for obtaining a residual quantity of a consumable consumed by a cleaning unit prior to starting printing on a plurality of print substrates. The control unit predicts a print executable number based on an obtained residual quantity a display/operation unit provides a prediction-result of a processable quantity. The screen printing apparatus enables preferred consumption prediction of consumable supplies such as a cleaning sheet of a cleaning unit and a cleaning agent at a required timing, thereby contributing to improvement of an operating ratio.

Screen printing apparatus

A screen printing apparatus includes a printing execution unit that performs screen printing on a substrate. At least one substrate support table that is provided movably along a specific direction orthogonal to the conveying direction. A table drive mechanism that moves the substrate support table at least between substrate entry and exit positions along a specific direction. The substrate entry and exit positions are set asymmetrically with respect to the specific direction. A printing execution unit drive mechanism is provided to drive the printing execution unit along the specific direction. A control unit is provided to control the printing execution unit drive mechanism so that the printing execution unit is driven to set the printing position on a substrate conveying path needed for the substrate support table to move from the substrate entry to the substrate exit.
