Description

  The present invention relates to a small piece member attaching apparatus for attaching a thin plate-like small piece member to a stationary member.

  Conventionally, for example, when creating a flexible printed circuit board, a small piece member made of a coverlay film is attached to a wiring pattern forming surface of a resin substrate on which a wiring pattern is formed to protect the wiring pattern. In such a case, an affixing device for affixing a small piece member cut into a predetermined shape to a substrate is used (for example, see Patent Document 1). In this pasting device, the reinforcing plate (small piece member) formed by the reinforcing plate generating device is pasted to a predetermined position of the base film held on the base film holding table by the reinforcing plate pasting arm, and the reinforcing plate is pasted. After the obtained base film is conveyed to the thermocompression bonding apparatus by the base film conveying apparatus, the base film and the reinforcing plate are thermocompression bonded by the thermocompression bonding apparatus.

  However, in the above-described conventional pasting apparatus, the base film holding table on which the reinforcing plate is pasted on the base film and the thermocompression bonding apparatus on which the reinforcing plate is thermocompression bonded to the base film are individually installed. It is necessary to move the base film in a state where the plate is attached with a base film transport device. For this reason, even if the reinforcing plate is accurately positioned with respect to the base film, the reinforcing plate may be displaced while moving from the base film holding table to the thermocompression bonding apparatus. Moreover, in the thermocompression bonding apparatus, since the entire base film with the reinforcing plate attached is heated, there arises a problem that energy loss is large and that accuracy becomes unstable due to the influence of heat. Furthermore, there is also a problem that deterioration due to heat tends to occur in the components of the thermocompression bonding apparatus. Further, the temperature distribution of the heated base film is likely to be non-uniform, and according to this, the strength of thermocompression bonding of the reinforcing plate to the base film tends to vary.

For this reason, the small piece member A can be heated while being conveyed, and the heated small piece member A is pressed against the placement portion 13a of the placement member 13, so that the small piece member A is directly attached to the placement portion 13a. Can be attached and fixed. Accordingly, the small piece member A can be installed and bonded to the stationary member 13 at the same time, and high-speed processing can be performed, and a shift may occur after the small piece member A is installed on the stationary member 13. Therefore, it is possible to attach with high accuracy.

  Moreover, since the small piece member A is heated by contacting the lower surface of the holding | maintenance part 24, while heating to each small piece member A becomes uniform, efficient heating becomes possible. Furthermore, since the holding unit 24 heats only the small piece member A that is in contact with the lower surface, it is possible to minimize the loss of heat energy and the occurrence of heat deterioration in other components of the transport apparatus 10a. In addition, since the transport device 10a includes a left-right direction movement mechanism 15, a front-rear direction movement mechanism 16, an elevating mechanism 17, and a rotation mechanism 18 that move the holding unit 20 in the left-right direction, the front-rear direction, the up-down direction, and the rotation direction. The direction of the small piece member A held by the holding unit 24 can be changed in any direction. Furthermore, since each heating / holding device 22 can be moved up and down individually by the holding device lifting / lowering mechanism 21, a plurality of heating / holding devices 22 can be controlled to be lifted / lowered individually. For this reason, the small piece member A can be accurately fixed with respect to the to-be-placed part 13a.

Moreover, since the upper part of the holding part 24 is connected to the lower part of the heater 23b, the heater 23b serves as both a member that supports the holding part 24 and a member that heats the holding part 24, thereby reducing the number of members. Thus, the structure of the heating and holding device 22 can be simplified. Further, since the small piece member A is sucked by the opening of the suction hole provided at the center of the lower surface of the holding portion 24, the small piece member A is sucked at the central portion, thereby enabling stable suction. And since the whole peripheral part of opening of the suction hole in the lower surface of the holding | maintenance part 24 becomes a part which heats the small piece member A, the area of the part fixed to the to-be-placed part 13a in the small piece member A can be enlarged. The fixing of the small piece member A to the stationary portion 13a becomes more reliable.
