A component mounting line has a screen printing apparatus and component mounting apparatuses. Each component mounting apparatus includes a first substrate carrying lane and a second substrate carrying lane, carries a first type substrate on which a first pattern has been printed in the first substrate carrying lane, performs a component mounting-relevant operation on the first type substrate, carries a second type substrate on which a second pattern has been printed in the second substrate carrying lane, and performs a component mounting-relevant operation on the second type substrate. The screen printing apparatus selects a type of the substrate to be carried in depending on whether a substrate is carried in the second component mounting apparatus downstream from the screen printing apparatus.

Component mounting line and component mounting method

A component mounting line has a screen printing apparatus and component mounting apparatuses. The screen printing apparatus carries in substrates based on substrate carrying-in order data which is determined so that alternate carrying-in in which a first type substrate and a second type substrate are alternately carried in and continuous carrying-in in which the first type substrate or the second type substrate which has a shorter line tact time is continuously carried in are mixed.

With a substantially intermediate position as a starting point, a syringe is reciprocated in an X-axial direction with a given reciprocation range by a plurality of times, and a stringiness portion that hangs down from a paste discharge port toward a mask plate is cut off in an intermediate portion thereof. The syringe is traveled to the substantially intermediate position, and with this position as a starting point, the syringe is reciprocated with a reciprocation range smaller than the reciprocation range of the paste cutting operation, and a part of the residual paste hanging from the paste shakes off downward. The syringe is traveled in an end direction of a guide member side, the syringe is rotated about an axial line, and translated into a horizontal storage posture.

Paste supply method

An object of the invention is to provide an electronic component mounting device and a work method of the electronic component mounting device, capable of ensuring safety of an operator who accesses a work line through a door portion, and avoiding reduction of workability. A space defined by a base () and a cover member () is partitioned by a partition member () to define a plurality of work line storing spaces (SP). A plurality of work lines () are stored in the respective work line storing spaces (SP) individually. When any of a plurality of door portions () provided in the cover member () so as to allow an access to an inside of the respective work line storing spaces (SP) is opened, an operation of a work line () stored in a work line storing space (SP) accessible through the opened door portion () is stopped.

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. Before starting production, a production pre-start precision evaluation process for evaluating a substrate positioning precision is executed by using a verification substrate and a verification mask, and after starting the production, a production post-start precision evaluation process for evaluating a substrate positioning precision after starting the production is executed by using a commercial production substrate and a commercial production mask.

Screen printing device and screen printing method

A holding mechanismis made up of a shaft supportthat is provided while joined to a joint and that has a vertically-oriented pivot, a shaft memberthat horizontally extends from the shaft supportand that is turnable around the pivot, and a fitting sectionthat is formed in a squeegee unitand to which the shaft memberis removably fitted. Thereby, the entirety of the squeegee unitbecomes removably attachable by only moving the squeegee unitin a horizontal direction.

Screen printer and screen printing method

An object of the invention to provide a screen printing machine allows, during maintenance work for one printing device, the other printing device to continue its screen printing work, and a method for controlling an inside temperature of a screen printing machine. A space surrounded by a base () and a cover member () is divided into two portions by a partition member (), and two printing devices () are accommodated in two working compartments (), respectively, which are defined by the base (), the cover member () and the partition member (), whereby temperature-controlled air is blown into each of the working compartments () via an air pipe () which branches into two air vents () opened to the respective working compartments ().

The present invention provides a device and a method for determining whether or not a component holder is good, which enable detecting component holders that are to affect correct component recognition and further enable preventing interferences between constituent devices, a component mounting apparatus with the determining device, and a component mounting method. The determining device has an illuminating device, a CCD camera and a controller to determine whether or not a suction nozzle is good based on luminance at a component hold face of the suction nozzle. The suction nozzle having light reflectance of the component hold face increased to a level whereat a correct recognition of an electronic component held by the suction nozzle is affected, can be detected accordingly. An interference preventing device is also provided, so that interference between the CCD camera and the suction nozzle can be prevented.

Method for determining whether a component holder is defective

An X-Y robot having a structure that linearly deforms along an X-axis direction and a Y-axis direction, a camera reference mark, and a control unit are provided. The X-Y robot causes no displacement of warp or the like and linearly deforms along only the X-axis direction and the Y-axis direction even if heat takes effect due to continuous operation. Therefore, if the amount of expansion and contraction of the X-Y robot due to heat is obtained by picking-up an image of the camera reference mark by a board recognition camera and the component placing position is corrected on the basis of the amount of expansion and contraction, then an electronic component can be mounted in a prescribed position or almost in the prescribed position.

Component mounting method

Disclosed are a component recognizing method and apparatus, and a component mounting method and apparatus, by which components with various heights held by a plurality of nozzles can be recognized continuously. The drive of a head is transmitted to nozzles, with surfaces to be recognized of components being controlled so as to be positioned in a recognizable range during respective recognizing operations of the components, and a continuous recognition is thereby made possible. The adjustment of heights of the surfaces to be recognized during the recognizing operations of the components is achieved by one drive unit and a plurality of drive transmitting units.
