Provided is a solder supply method of supplying, onto a mask sheet, solder to be printed on a printed circuit board. The method includes calculating an amount of solder supplied for a plurality of points in an X direction that is a lengthwise direction of a squeegee, and changing the amount of solder supplied at each point in the X direction based on a result of the calculation.

Method of supplying solder to printed circuit board

A printer includes: a mask; a cleaning section configured to perform cleaning of the mask by movement relative to the mask in a predetermined direction parallel with an under surface of the mask; a mask holding section capable of turning the mask about an axis perpendicular to the under surface of the mask while holding the mask; and a control section configured to perform a control such that the cleaning is performed on the mask placed in a predetermined position about the axis.

Printer

A printing device includes a mask raising/lowering mechanical part for raising/lowering, in a state of holding a screen mask, the screen mask in a vertical direction and positioning the screen mask relative to a substrate, a frame part disposed in a state of being independent from a raising/lowering operation of the screen mask, and a print head unit provided movably to the frame part and performing squeegeeing of the screen mask to which a solder has been supplied.

Printing device

This viscous material feeder includes a nozzle to discharge a viscous material stored in a storage portion storing the viscous material and a feeding mechanism transferring the viscous material from the storage portion to the nozzle and discharging the viscous material from the nozzle. The nozzle has a bent feed route to guide the viscous material from the storage portion to a tip of the nozzle and is configured to be dividable along the bent feed route.

Viscous material feeder and viscous material printer

Disclosed is a printing apparatus which comprises: a base; a frame member installed on the base; a printing section supported by the frame member to subject a board to printing; a board conveying segment provided on the base displaceably; a control section for controlling the driving of the board conveying segment; a mark provided on the frame member; and an image pickup section mounted on the board conveying segment to pick up an image of the mark, wherein the control section is operable to cause the board conveying segment to be displaced so as to allow a board to be set in the printing zone, and, based on the image of the mark picked up by the image pickup section, to perform a strain compensation for correcting an error in displacement of the board conveying segment due to a strain of the driving mechanism.

Printing apparatus

A grommet includes an outer body and an inner body. The outer body, is formed with a wire insertion hole through which a wire is inserted, and has a panel fitting portion at a circumferential portion thereof. The panel fitting portion fits in a first panel hole having a first diameter. The inner body, is attached to the outer body, and has a locking fitting portion at a circumferential portion thereof. The locking fitting portion fits in a second panel hole having a second diameter smaller than the first diameter and locks an inner edge portion of the second panel hole.

Grommet

A printing device capable of improving the printing accuracy by preventing positional displacement of a stencil applies paste on a stencil onto a substrate by spreading the paste by sliding a squeegee along a surface of the stencil disposed on the substrate. Outer attracting means for holding the stencil by attracting an undersurface side thereof is provided on the outside of a squeegee sliding region in which the squeegee slides over the stencil.

Printing device and printing method

A cover mounting structure of a waterproof boxwhich is composed of a container bodyand a coverto be mounted on an opening of the container body. The container bodyincludes side walls in a double-wall structure composed of an inner walland an outer wall, the inner wallbeing projected longer than the outer wall. The coverincludes attached walls each of which is provided with an outer groovedefined between an outer wall portionand a middle wall portion, and an inner groovedefined between the middle wall portionand an inner wall portion, so that the covercan be mounted to the container bodyby respectively inserting the inner walland the outer wallof the container body into the inner grooveand the outer grooveof the cover. On the middle wall portionwhich is opposed to the relevant middle wall portionin contact with an outer face of the inner wallwhich is projected longer than the outer wall, there is provided a guide partfor guiding the opposed middle wall portioninto a gap between the outer walland the inner wall

Cover mounting structure of waterproof box

A waterproof structure of an electric parts-containing box includes a containing box body and a front cover which is mounted on the containing box body so as to cover a opening portion thereof. Either the containing box body or the front cover has a through hole. A water intrusion suppressing portion is formed on a face of either the containing box body or the front cover so as to suppress an intrusion of water which flows on the face into the through hole.

Waterproof structure of electronic parts-containing box

A grommet includes a first cylindrical portion for passing a member threthrough and a second cylindrical portion connected to the first cylindrical portion through an annular connection portion formed at an outer peripheral face of the first cylindrical portion. The second cylindrical portion has a fitting groove which formed in an outer peripheral face thereof for fitting on an inner peripheral edge of a through hole in a mounting plate. A first junction portion is formed between the annular connection portion and the first cylindrical portion. A second junction portion is formed between the annular connection portion and the second cylindrical portion. A form of the grommet changes between a first state in which an angle formed the annular connection portion with the first cylindrical portion in cross section is an acute angle and a second state in which an angle formed the annular connection portion with the first cylindrical portion in cross section is obtuse angle. At least one of the first cylindrical portion and the second cylindrical portion are formed so that the grommet autonomously restores in the first state.

A clip-attaching structure is provided, which includes: an attachment body; a mating attachment body to which the attachment body is attached; and a clip provided, in accordance with an outer shape of the attachment body, with a baseplate, a first side plate extending from one side of the baseplate and having an engaging portion, and a second side plate extending from the other side of the baseplate, which clip fixing the attachment body to the mating attachment body, wherein an engagement portion to which the engaging portion engages is provided on the mating attachment body, and the attachment body is fixed to the mating attachment body by fixing the clip to the mating attachment body.

Clip-attaching structure

In a waterproof structure of an electrical junction box which renders the electrical junction box waterproof by bringing a stepped section of a cover into contact with a flange section of a case a protuberance to be brought into pressing contact with the stepped section or the flange section is formed along the periphery of the stepped section or the flange section In order to provide effective sealing, the leading edge of the protuberance is brought into line contact with the flange section or the stepped section Further, a skirt wall is formed so as to extend downwardly from the stepped section and a second skirt wall is formed so as to extend from the flange section along the skirt wall
