본 발명은 스크린프린터의 마스크 자동교체장치에 관한 것으로, 스크린프린터에 기 설치된 마스크를 신규 마스크로 자동교체가 가능하여 불필요한 시간과 인력 낭비 및 이에 의한 교체작업의 번거로움 없이 새로운 인쇄회로기판의 생산으로의 전환이 빠르게 가능하고, 이를 통한 생산성 향상 및 작업시간의 단축을 통한 효율성이 증대되는 장점과 마스크를 인력에 의한 무리한 교체작업이 아닌 자동공정을 통한 빠른 교체작업을 통해 공정조건의 변화율을 최소화함에 따라 교체 작업에 따른 제품불량 유발을 최소화할 수 있고, 마스크 교체에 따른 이동거리를 최소화하여 마스크 교체에 따른 시간을 최소화하여 빠르게 교체가 가능하고, 스크린프린터의 인쇄부 상측으로 결합하여 사용함에 따라 장비의 크기가 작고, 별도의 설치공간도 필요없어 설치면적의 제약이 없는 스크린프린터의 마스크 자동교체장치에 관한 것이다.
摘要:
Systems and methods of removing and cleaning a stencil in a stencil printer include removing a used stencil from a stencil printer with the assistance of a movable cart, transporting the used stencil by the movable cart to a cleaning station, removing the used stencil from the movable cart, delivering the used stencil to the cleaning station, cleaning the stencil, removing a cleaned stencil from the cleaning station, and delivering the cleaned stencil to the movable cart for future use.

A framed stencil for surface mount technology (SMT) is provided. The frame assembly includes a frame member and a binding insert. The frame member includes an inner perimeter portion and an outer perimeter portion that cooperates with the inner perimeter portion to define an elongated channel. The outer perimeter portion includes a first cantilever portion that extends over the elongated channel and towards the inner perimeter portion. The binding insert is configured for releasable insertion into the elongated channel. The binding insert includes a base and a tongue. The base configured to interface with a mesh substrate to facilitate coupling therebetween. The tongue is coupled to the base and extends substantially horizontally from the base. When the binding insert is inserted into the elongated channel, the tongue extending beneath the first cantilever portion to facilitate retention of the binding insert to the frame member. Methods are also provided.

A stencil printer is configured to print an assembly material on an electronic substrate. The stencil printer includes a frame, a stencil coupled to the frame, a support assembly coupled to the frame, and a print head gantry coupled to the frame. The print head gantry includes an elongate beam that rides along rails provided on the frame and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The print head assembly includes a print head having a squeegee blade assembly configured to roll solder paste along the stencil. The stencil printer further includes a solder paste bead recovery system configured to remove a bead of solder paste from a top surface of the stencil and to deposit the bead of solder paste onto a new replacement stencil.

A stencil printer includes a frame, a stencil coupled to the frame, and a support assembly coupled to the frame, with the support assembly including tooling configured to support the electronic substrate in a print position beneath the stencil. The stencil printer further includes a print head assembly coupled to the frame in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The print head assembly includes a squeegee blade assembly and at least one paste cartridge to deposit solder paste on the stencil. The stencil printer further includes an end effector configured to pick up and release items from a tooling tray. The stencil printer further includes a movable cart configured to interface with the stencil printer to deliver changeover and/or replacement items within a stencil printer.

The invention relates to a rotary press comprising a printing cylinder (1), a dye supply (2) for providing the printing cylinder with dye, and a dye chamber (3) that can be connected to a dye source. The dye chamber has a dye outlet (4) in the form of a slit (14), extending essentially parallel to the printing cylinder axis and aligned with the printing cylinder so that the dye can flow out towards the cylinder.
摘要:
A mandrel for electroforming printing screens, the mandrel comprising: a mandrel plate onto which metal is to be deposited to form a printing screen, the mandrel plate including a main deposition surface onto which metal is to be deposited to define a main body of the printing screen, at least one pair of edge sections at opposed edges of the main deposition surface which include edge deposition surfaces which extend out of a plane defined by the main deposition surface onto which metal is to be deposited to define attachment elements of the printing screen, and corner sections at respective corners of the deposition surface; non-conductive elements, as edge elements, which are disposed at the edge sections such as to define an extent of the edge sections; and non-conductive elements, as corner elements, which are disposed at the corner sections such as to shield the same and define an extent of the main deposition surface at the corner sections.
