A screen printer comprising: a conveyance device configured to convey a board; a board holding device configured to position a conveyed board at a printing position; a stencil holding device configured to attach a stencil above the held board; a squeegee device configured to fill pattern holes of the stencil with solder paste; a board raising and lowering device configured to raise and lower the board positioned by the board holding device; and a control device configured to perform drive control of each the above devices, the control device including a standby printing processing section configured to raise the board from below with respect to the stencil such that the board contacts the stencil, stand by in a state with solder paste filled in the pattern holes, and lower the board to separate the board from the stencil in accordance with a board conveyance signal.

Screen printer

A screen printer that measures a tension of a mask in a machine, including a mask holding device configured to hold a mask; a board device configured to position a board from below with respect to the mask held by the mask holding device; a squeegee device configured to apply and spread a cream solder on an upper surface of the mask; a mask pressing device configured to press the mask at a set pressure by a pusher which is installed on an upper travelling device or a lower travelling device with respect to the mask; a mask measurement device, installed on the upper travelling device or the lower travelling device to be opposed to the pusher, which is configured to measure a height of the mask; and a tension measurement device configured to calculate a tension of the mask based on a measured value of the mask measurement device.

Screen printer having mask pressing device for determining tension of mask by calculating mask deflection amount

A screen printing machine configured to print solder onto a surface of a circuit board using a screen mask. The screen printing machine is provided with: a screen mask arranged at a top side of the circuit board; a box member arranged at an underside of the circuit board including a space that is closed by the circuit board; a negative pressure generator connected to the space of the box member and configured to create negative pressure inside the space; a sensor configured to detect a pressure inside the space; and a control device configured to control the negative pressure generator based on the pressure detected by the sensor.

Screen printing machine

A printing apparatus of the present disclosure is for performing printing of a viscous fluid onto a print target using a screen mask, the printing apparatus including: a moving section configured to perform at least one of moving an exchangeable member to an exchange position or loading and unloading of the exchangeable member, for at least two types of the exchangeable member that, out of a cartridge configured to house the viscous fluid, a squeegee, a screen mask, a cleaning member used to clean the screen mask, and a support member configured to fix the print target, include at least one out of the cartridge, the squeegee, and the cleaning member; and an exchange control section configured to control the moving section to perform exchange processing of exchanging the exchangeable member.

Printing apparatus and accommodation apparatus

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.

Board work device having support member conveyance section for conveying board support member

A first conveyor belt and second conveyor belt are disposed on guide rail which is disposed so as to extend in a circuit substrate conveyance direction. Then, the circuit substrate supported by both the conveyor belts of the first conveyor belt and the second conveyor belt is held by substrate holding device, and work is performed on the held circuit substrate. In the transfer device having such a structure, for example, when the circuit substrate on which an operation has been completed is conveyed out by the second conveyor belt, a new circuit substrate is conveyed into the transfer device by the first conveyor belt. In this way, it is possible to perform printing work on a new circuit substrate at an early stage and shorten a cycle time.
