In a mask printing machine, a target through hole, which is at least one of multiple through holes formed on the mask, is imaged by an imaging device when the board is below the mask and is at a separated position that is separated from the mask, and when the board is at a contact position in which an upper surface of the board contacts a lower surface of the mask, respectively. Based on a captured image, when the board is at the separated position, and a captured image when the board is at the contact position, it is possible to acquire the movement state of at least one target through hole when the board is lifted from the separated position to the contact position.

A feedback information generation method for a solder inspection apparatus includes: receiving an input of information on the number of buffers which are disposed between the solder inspection apparatus and a screen printer for printing solder on printed circuit boards and are configured to support the printed circuit boards to be introduced into the solder inspection apparatus so as to put the printed circuit boards on standby; generating feedback information by using the input information and an inspection result of the printed circuit boards by the solder inspection apparatus; and transmitting the feedback information to the screen printer. Feedback information may be generated in consideration of the number of buffers, thereby preventing the feedback information from being excessively generated as well as ensuring the accuracy of the feedback information.

The present disclosure discloses a printing machine. The printing machine includes a carrying platform for carrying a to-be-printed board, a frame above the carrying platform, a roller-shaped screen printing plate with printing graphic meshes, and an ink supply device within the roller-shaped screen printing plate. The roller-shaped screen printing plate is mounted to the frame in a manner that the roller-shaped screen printing plate is capable of rotating relative to the carrying platform.

An alignment system for a workpiece printing machine comprises a stencil support and a workpiece support, and a planarity control mechanism having at least two actuators arranged to effect relative rotation of the stencil support and workpiece support about both the horizontal axes.

Screen printer 10 is for screen printing solder paste 13 loaded on an upper surface of stencil 12 onto board S using one of first and second squeegees 71 and 72. Screen printer 10 is provided with a stencil frame holding rail that holds stencil frame 12a of stencil 12, pair of board holding members 36 and 38 that hold board S, raising and lowering table 16 that raises and lowers board holding members 36 and 38, and pair of stencil supporting members 50 and 52 that support stencil 12 from below at a portion outside a printing region of stencil 12 used for screen printing. Stencil supporting members 50 and 52 are provided independently from raising and lowering table 16. Therefore, the load applied to raising and lowering table 16 is reduced. Also, there is increased design freedom with respect to members and the like loaded on raising and lowering table 16.

Print station (1) for a screen printing machine, said print station (1) having a screen frame (14) and a print base (8) for receiving a product (10, 10A) to be screen printed through said screen print frame (14), said print station (1) comprising a screen frame elevation mechanism comprising a first shaft (6) and wherein the screen frame (14) is rotatable about said first shaft (6), wherein said first shaft (6) is movable between a first and a second position, such that the screen frame (14) is translationally moveable relative to the print base (8) when the screen frame (14) is in a printing position relative to the print base (8), further comprising a rotatable circular-section second shaft (5), wherein the first shaft (6) is solidly fixed to the second shaft (5) and the first shaft rotation axis is offset from the second shaft rotation axis. Also, a method of operating the print station (1) for a screen printing machine, comprising: lowering, or raising, the screen frame (14) into, or from, a printing position relative to the print base (8) by simultaneously rotating the screen frame (14) about said first shaft (6) and also moving said first shaft (6) such that the screen frame (14) moves translationally relative to the print base (8).

The application relates to a printing device for printing onto substrates, in particular solar cells, wafers or printed circuit boards, including a squeegee means and including at least one printing table, wherein the squeegee means is arranged above the printing table, and including at least one conveying means, by means of which a substrate can be transported away in each case to a printing nest below the squeegee direction and away out of the printing nest after the printing process has taken place. It is provided that the printing table has several conveying means, which are arranged side by side and aligned parallel to one another and which each have at least one printing nest, and that the squeegee means has at least one squeegee, which can be moved over each printing nest in order to print successively onto the substrates, which are arranged in the printing nests.
