A substrate cleaning apparatus for cleaning a front-side clean target surface 1a and a back-side clean target surface 1b of a edge portion of a substrate 1 by wiping surfaces 12a, 12b of a cleaning tape 12. The substrate cleaning apparatus includes a presser member 11a for pressing the cleaning tape 12 against the clean target surface 1a, a presser member 11b for pressing the cleaning tape 12 against the clean target surface 1b, a tape path passing through between the presser member 11a and the clean target surface 1a and between the presser member 11b and the clean target surface 1b, a moving device for moving the cleaning tape 12 and the substrate 1 relative to each other in a longitudinal direction of the edge portion. The tape path makes the cleaning tape 12 passed through between the presser member 11a and the clean target surface 1a in a direction orthogonal to the longitudinal direction of the edge portion of the substrate 1 with the wiping surface 12a facing the clean target surface 1a, next makes the cleaning tape 12 looped so that the wiping surface 12b faces the back side of the substrate 1, and subsequently makes the cleaning tape 12 passed through between the presser member 11b and the clean target surface 1b in a direction identical to the passage direction between the presser member 11a and the clean target surface 1a with the wiping surface 12b facing the clean target surface 1b.

In a chip reversing method for holding and vertically reversing a chip placed by a bonding nozzle, the chip is held on a chip holding unit disposed in a reversing member and is vertically reversed by turning the reversing member downward on an reversal shaft. After the reversed chip was received by a chip receiving unit, this chip receiving unit is lowered to a retracted position to return the reversing member to an original position. In this state, the chip receiving unit is raised to position the chip at a height level L for a chip transferring action. As a result, the reversing member does not protrude to above the height level for the chip transfer thereby to interfere with another mechanism, so that the chip mounting actions can be made efficient.

A component mounting apparatus and method for mounting a plurality of components on a board. The aparatus is provided with a board holding device for holding the board at a board holding position, a first mounting head for holding and taking out a component fed from a first component feeding position and mounting the component on the board held at the board holding position, a second mounting head for holding and taking out the component fed from a second component feeding position and mounting the component on the held board, and a component feeding device having a wafer holding table for holding a wafer on which the respective components are fed so that the wafer holding table can be moved reciprocationally between the first component feeding position and the second component feeding position.

In a component mounting work area, two electronic circuit boards are placed in a zigzag manner and components are mounted independently on each board. Two sets of working their drive units, board conveying/holding devices recognition cameras and so forth are also arranged. The board conveying/holding devices for holding boards are moved to positions close to component feed units, and components are mounted in respective mounting areas.
摘要:
An apparatus and a method for mounting electronic components are provided which shorten a cycle time required for mounting and enable a component mounting machine to be arranged in a small area. There is provided a controller, so that a retreat control for a second electronic component is performed to a second component feeder so as to avoid an interference if a first electronic component or a component holder interferes with the second electronic component of the second component feeder because of movement of a mounting head. The time conventionally required for moving up and down a component holder can be reduced, and moreover the need of uselessly moving along a detour at a time of moving the mounting head is eliminated. The cycle time can be shortened, and eventually costs can be reduced.
摘要:
When two mounting units for performing a series of component mounting operations constituted of component holding, component recognition, and component placing are arranged, operational control is executed so that, while a component recognition or board recognition operation is performed in either one of the two mounting units, the component placing or component holding operation is not performed in the other of the mounting units.

An electronic component mounting apparatus which employs a first air feed device connected to an air passage at one end part of a spline shaft, and a second air feed device connected to the air passage in the vicinity of the other end of the spline shaft. The first and second air feeds function to supply air to the air passage to return an interior thereof to atmospheric pressure. The time required to return the vacuum pressure in the air passage to atmospheric pressure can be shortened by the use of the two separate air feeds.

When a nozzle is selected, a piston rod (46) of a nozzle selecting cylinder (45) positioned at a lower end position unfailingly forms a gap (A) with an upper end of a nozzle elevating shaft (55) so that the piston rod of the cylinder (45) is not brought into contact with the nozzle elevating shaft at the time of nozzle selecting. Only when an elevating member (58) is lowered by a drive by an elevation drive motor (56), the piston rod (46) is brought into contact with the nozzle elevating shaft (55).
摘要:
A filling squeegee and a scraping squeegee are provided in a printing apparatus. The filling squeegee is moved without contacting a surface of a mask in order to fill a solder paste into openings of the mask. Unnecessary solder paste on the surface of the mask is scraped by the scraping squeegee. The solder paste is prevented from being improperly filled in or scraped from the openings even if a speed of the squeegee is increased, so that the solder paste can be printed stably on circuit board.
