Abstract: In an image recognition method, the image of a cream solder 9 printed on a rectangular electrode 16 having a solder leveler formed is picked up and recognized to identify the cream solder 9. An illuminating unit having white light source parts 35W arranged in the radial oblique directions of 45° is used to apply white color illumination lights from a light applying direction in which an angle of θ1 formed by the light applying direction and a horizontal plane in a vertical plane is 45° or smaller and from a light applying direction in which an angle of θ3 formed by the light applying direction and the boundary of the electrode 16 in a horizontal plane is 75° or smaller. Thus, regularly reflected lights from a solder leveler forming surface 16a with a glossiness are not received by an upper camera to identify a solder surface 9a and the solder leveler forming surface 16a with good accuracy.

Abstract: The clearance ‘d’ between a substrate 3 and a mask 2 can be reduced at the time of the position recognition by horizontally offsetting two recognition devices 53,54 for recognizing the substrate 3 and the mask 2. Therefore, since the ascending stroke of the substrate 3 can be shortened at the time of the position alignment to contact the rear face of the substrate 3 with the rear face of the mask 2, the position misalignment of the substrate in the horizontal direction caused by the raising is suppressed. Accordingly, it is possible to suppress the reduction of the position alignment accuracy with the mask 2.

Abstract: A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. A three dimensional detector, such as a laser, is used to determine the extent to which the pattern hole is filled with the cream solder. Based on the determination result, the printing operation is modified, with respect to the positioning of the mask plate and substrate, to maintain the printing quality.

Abstract: A screen printer for printing paste on a board by sliding a squeegee head on a mask plate. A pushing plate pressurizes solder paste in the squeegee head, and pressurized paste is led to a paste container from both outer parts in a printing width direction inward towards a printing center through a solder dispensing hole provided on both ends of the paste container. This configuration allows to print in accordance with the time-line supply sequence, regardless of the printing width of the board to be printed. This screen printer thus prevents the degradation and the consequent need for disposal of solder paste due to its retention in the squeegee head for long periods.

Abstract: In a screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate, a predetermined measuring position of the mechanisms in the screen-printing apparatus is measured three-dimensionally by a three-dimensional measuring device. Based on the measured result, a predetermined measuring point on an object to be measured is determined on a position relative to the origin of the mechanical coordinate system in the screen-printing apparatus, and the origin position on a control program can be set. As a result, machine adjusting operation and teaching operation in the screen-printing apparatus can be simplified with high accuracy.

Abstract: Cream solder stored in a squeegee head is pressurized by a pressurizing plate, and the squeegee head is slid on a mask plate, so that the cream solder is printed onto a substrate via pattern apertures. This is done by a screen printing apparatus, in which pressurized solder is accommodated, and the solder is brought into contact with a surface of the mask plate via an opening formed on a lower face of the cell. A rectifier is disposed in the cell for blocking the cream solder from flowing into a specific area just above the opening. This structure allows the solder to flow into the opening in a slant direction, and causes the solder to roll. This mechanism prevents the solder from being hardened due to staying stagnant just above the opening, and thus prevents defective printings.

Abstract: A screen printing method and apparatus are capable of maintaining a constant attack angle between a squeegee and a mask plate, regardless of the surface condition of the mask plate. A squeegee head, including a pair of squeegees, is rotatably supported by a retainer with respect to a horizontal axis that is at a right angle to a squeegeeing direction. The rotatably supported squeegee head is pushed by a cylinder against the mask plate. Accordingly, the attack angle is kept constant to improve the printing quality even if a substrate has a curved portion.
