Abstract

PURPOSE:To make it possible to hold a board securely without changing a plate by adopting a fixing device comprising a pin to fix a board, a plate to be mounted with this pin, and a drive to move the plate vertically, and fixing the pin with the plate in any position by a magnet so that its fixing position may be changeable. CONSTITUTION:After a board 1 comes to a half at a specified position of a carrier rail, a pin 3 and a plate 4 are adapted to rise by a drive means 7 so that the board 1 may be fixed on the upper carrier surface of the carrier rail 3. When the board 1 is fixedly held, it is necessary to adjust the position of the pin so that it may not interfere a chip 6. The provision of a magnet designed to fix the pin 3 to either the pin 3 and the plate 4 eliminates the need for a plate to be mounted with the pin for each board and fixes the board securely.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a substrate holding and fixing device for holding and fixing a substrate at a predetermined position on a substrate transport rail.

2. Description of the Related Art In recent years, electronic component mounting apparatuses have focused on shortening board switching time, improving work efficiency, and lowering costs in high-mix, low-volume production.

This figure shows the substrate holding and fixing configuration of the device, and the operation when a substrate at a predetermined position on the substrate transport rail is held and fixed with the upper surface of the transport surface of the transport rail as a reference.

Figure 5 shows a state in which the board is held by a plate with holes for mounting pins to match the board after single-sided mounting in Figure 4, and llb is a single-sided mounted board held and fixed at a predetermined position on the board transport rail. The latter board, 12b is a transport rail for transporting the board 11b, 13b is a pin for holding and fixing the board 11b, 14t) is a plate with a hole for mounting the pin 13b in accordance with the board 11b, 15b is a chip component, Reference numeral 16b is a drive unit for driving the plate 14b up and down.

Problems to be Solved by the Invention However, with the above configuration, as shown in FIGS. 3 to 5, it is possible to attach and fix pins at equal intervals on a single-sided board, but when mounting on both sides, On the board for mounting, the pins are installed so as not to interfere with the chip components of the mounting agent, but since the pins cannot be installed at equal intervals, the board may warp or bend, and when the chip components are mounted, the pins may be misaligned or mounted. A defect occurs. Furthermore, as shown in FIG. 5, in order to securely hold and fix the board, there was a drawback that a plate had to be made with the hole positions changed in order to attach the pins.

Tree climbing 1! The purpose of JJ is to eliminate the drawbacks of the conventional technology, and even if the type of board changes, the board can be reliably held and fixed without changing the plate on which the pins are attached, reducing replacement time and manufacturing costs. An object of the present invention is to provide a possible substrate holding and fixing device.

Means for Solving the Problems A substrate holding and fixing device of the present invention comprises a pin for holding and fixing a substrate, a plate to which the pin is attached, a magnet attached to an arbitrary position on the plate, and a drive unit for driving the plate up and down. The pin is fixed at any position on the plate by a magnet so that its position can be changed.

According to the present invention, even if the type of substrate changes, there is no need to replace the plate on which the pins for holding and fixing the substrate are attached, so that the replacement time and manufacturing cost can be reduced.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 shows a substrate holding and fixing device of the electronic component mounting apparatus according to the first aspect of the present invention. In the figure, 1 is a board after single-sided mounting that is held and fixed at a predetermined position on the board transport rail, 2 is a transport rail that transports the board 1, 3 is a pin for holding and fixing the board 1, and 4 is a pin 3. mounting plate,
5 is a magnet attached to the pin 3 for attaching the pin 3 to the plate 4, 6 is a chip component, and 7 is a drive unit for driving the plate 4 up and down.

Figure 2 shows the case where a magnet is attached to the plate side and the pin is fixed, 3 is the pin for holding the board 1, 4 is the plate to which the pin 3 is attached, and 5 is the pin for attaching the pin 3 to the plate 4. This is a magnet attached to plate 4.

Next, the operation will be explained.

First, in FIG. 1, after the substrate 1 stops at a predetermined position on the transport rail 2, the pins 3 and the plate 4 are raised by the drive unit 7, and the substrate 1 is held and fixed on the upper surface of the transport surface of the transport rail 2. Further, when holding and fixing the board 1, the mounting position of the pin 3 is adjusted so as not to interfere with the chip component 6.

FIG. 2 shows a state in which the magnet 5 is attached to the plate 4 and the pin 3 is fixed.

As described above, according to this embodiment, by providing the magnet 5 for fixing the pin 3 to either of the plates 4, the pin 3 can be attached to each board even when the type of board changes. It is possible to securely hold and fix the board without making a plate, and it is possible to prevent component displacement and poor mounting when chip components are mounted.

Effects of the Invention According to the present invention, by attaching a magnet to either the pin for holding and fixing the board or the plate to which this pin is attached, the position of the pin can be freely adjusted, and the type of board can be changed. Even in such a case, it is possible to securely hold and fix the board without making a plate 1 to match the board, and its practical effect is great.
