A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.

A printing system for printing substrates, in particular circuit boards, such as wafer and solar cells, has a printing device, with a printing table on which the substrate can be positioned and a print head associated with the printing table for printing the substrates positioned on the printing table, has a feed device for feeding the substrates to be printed to the printing device, a discharge device for discharging the printed substrates from the printing device, and a plurality of substrate supports on which each of the plurality of substrates can be supported. The feed device, printing device and discharge device convey the substrate supports with the substrates located thereon. The feed device collects plurality of substrate supports and feeds them to the printing device. The printing device prints the substrates on the collected substrate supports, and the discharge device separates and discharges these collected substrate supports.

A printing device including a conveyance rod which discharges and introduces a screen mask and a board support member; and a control section. The control section performs a mask exchange process including a mask discharge process of discharging the screen mask to be discharged and a mask introduction process of introducing the screen mask to be introduced by controlling a conveyance rod. In addition, the control section performs a support member exchange process including a support member discharge process of discharging the board support member to be discharged and a support member introduction process of introducing the support member to be introduced by controlling the conveyance rod.

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.

Tooling for supporting workpieces during a printing operation, comprises a support tower comprising a base and a head, the head being positioned vertically above the base in use, the head being relatively moveable with respect to the base in a horizontal plane in use, the head having first and second support surfaces located at an upper end thereof, each of the first and second support surfaces being adapted to support a respective workpiece thereon, wherein the first support surface is relatively moveable with respect to the second support surface in a vertical direction in use between a printing configuration in which the first and second support surfaces are substantially coplanar in the horizontal plane, and a pre-printing configuration in which the first and second support surfaces are spaced in the vertical direction.

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.

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 screen printing machine for appropriately contact between a mask and a board, comprising: a mask-holding device configured to hold a mask; a board-positioning device configured to hold a board and to position the held board with respect to a mask held by the mask-holding device from below; a squeegee device configured to spread a cream solder with respect to the mask; a height-measuring device configured to measure the height of the mask and the board; a control device configured to control each device, and to calculate the thickness of a mask lower layer, integrally formed with the mask, based on the measurement values obtained from the height-measuring device; and an operation display device configured to input operation and to display calculation values from the control device, and the like.

A printing device including a conveyance rod which discharges and introduces a screen mask and a board support member; and a control section. The control section performs a mask exchange process including a mask discharge process of discharging the screen mask to be discharged and a mask introduction process of introducing the screen mask to be introduced by controlling a conveyance rod. In addition, the control section performs a support member exchange process including a support member discharge process of discharging the board support member to be discharged and a support member introduction process of introducing the support member to be introduced by controlling the conveyance rod.
