Abstract: A component supplying apparatus includes a main tape entering port, a component supply port through which components are picked up from a carrier tape, a main tape path extending in a body part from the main tape entering port to the underside of the component supply port, a top tape removing part removing the top tape from the carrier tape on the main tape path upstream of the component supply port, a sub tape entering port, a sub tape path meeting a slope path portion of the main tape path at a meeting point upstream of the top tape removing part, and at least one sprocket wheels engaging with the carrier tape on the main tape path downstream of the meeting point. A length of the sub tape path is shorter than a length of the main tape path from the main tape entering port to the meeting point.

Abstract: A component supplying apparatus comprises a tape guide surface facing a lower surface of the carrier tape, a preceding tape contact part climbing onto a upper surface of the preceding carrier tape, and a subsequent tape blocking part configured to wait on the upstream side of the preceding tape contact part in a tape feeding direction while keeping a distance from the tape guide surface so as to enable the carrier tape to pass between the subsequent tape blocking part and the tape guide surface, and to move downwardly toward the preceding carrier tape when the preceding tape contact part is climbed onto the preceding carrier tape. The subsequent tape blocking part keeps the subsequent carrier tape waiting by contacting a front end of the subsequent carrier tape stacked on the preceding carrier tape onto which the preceding tape contact part climbs.

Abstract: Prior to a mark imaging process executed for the purpose of detecting a position of recognition marks for positioning the substrate and the mask, an optical axis calibration processing process of detecting a horizontal relative position between imaging optical axes, and a surface correction data creation processing process of detecting a local positional deviation of the imaging optical axes, which is caused by the travel of the imaging unit, are executed.

Abstract: A challenge to be met by the present invention is to provide a screen printer arranged so as to be able to readily perform both replacement of squeegees and operation for filling a paste feed syringe with paste. A paste feed syringe (14) is configured so as to be able to sway around an axial line (41) that downwardly extends from a squeegee base (30) with respect to a horizontal line (HL) parallel to a direction of reciprocal movement of the squeegee base (30), and also be able to change its position between a paste feed attitude having an imaginary extension within a vertical plane at an oblique angle such that a nozzle (14a) provided at a lower end of the paste feed syringe comes to a position immediately below squeegees (15) and a storage attitude which is turned from the paste feed attitude through about 90 degrees around an axial line (41).

Abstract: In the liquid application device 1, when the magazine 5 for feeding the substrate installed in the substrate feed part is exchanged for a new magazine 5 for feeding the substrate, the magazine 5 for collecting the substrate is removed from the substrate collecting part R2, the magazine 5 for feeding the substrate that is installed in the substrate feed part R1 so far is moved to the substrate collecting part R2 as a subsequently used magazine 5 for collecting the substrate, and then, the new magazine 5 for feeding the substrate is installed in the substrate feed part R1.

Abstract: A liquid-application device 1 includes a substrate feed part R1 where a magazine 5 for feeding a substrate is installed in which the substrates 4 before a liquid Q is applied are accommodated, an application head 14 which applies the liquid Q to the substrate 4 taken out from the magazine 5 for feeding the substrate installed in the substrate feed part R1 and moved to a working position and a substrate collecting part R2 where a magazine 5 for collecting the substrate is installed in which the substrates 4 with the liquid Q applied by the application head 14 are accommodated. The substrate feed part R1 and the substrate collecting part R2 are arranged and located in parallel in the vertical direction.

Abstract: Provided are a screen printer and a screen printing method capable of reducing poor printing by realizing smooth rolling of a paste. When a squeegee 32 is slid on a mask 5 so as to transfer a paste Ps to a substrate 2, leakage prevention members 33 are slid on the mask 5 along with the squeegee 32 so as to prevent the paste Ps on the mask 5 from leaking out of both sides of the squeegee 32. The height H0 of the paste Ps on the mask 5 is greater than the height Hm of the leakage prevention members 33 from the upper surface of the mask 5, and the paste Ps located at a position greater than the height Hm of the leakage prevention members 33 is rolled.
