Electronic component supply bases 9 are respectively formed on the front and rear sides of the base 6 (in FIG. 5A, the rear electronic component supply base 9 which is obliquely upward to the right in the figure is hidden and cannot be seen. (B), the rear electronic component supply base 9 is not shown). A large number of tape cassette type electronic component supply devices (hereinafter simply referred to as tape type component supply devices) 11, 50 to 70, are arranged on the electronic component supply base 9.
[0010]
Above the base 6, there are two X-axis rails 12 and a Y-axis supported on the X-axis rails 12 so as to be slidable in the X-axis direction (from the lower right to the upper left).

In the electronic component mounting apparatus 1 having such a configuration, a predetermined electronic component supplied to the suction unit by the tape cassette type component supply device 11 or a tray type component supply device described later is sucked by the suction nozzle of the work head 15, The sucked electronic component is mounted on a predetermined mounting position of the substrate 8. The tray-type component supply device is a component supply device that supplies electronic components such as large-sized components and irregular-shaped components that cannot be supplied by the tape cassette-type component supply device 11 to the electronic component mounting device 1.
[0013]
FIGS. 6A and 6B are diagrams showing various arrangement relationships between such a tray-type component supply device and the electronic component mounting device 1 described above. The tray-type component supply device 16 (16a, 16b) shown in FIG. 4A moves relative to the electronic component mounting device 1 as indicated by arrows A and B in the figure, and moves to the side of the electronic component mounting device 1. The tip of the shuttle conveying beam 17 is inserted into the inside from the side opening of the electronic component mounting apparatus 1, and the electronic component is supplied to the work head 15 from the suction point at the tip.
[0014]
Also, the tray-type component supply device 16 (16c, 16d) shown in FIG. 6B moves relative to the electronic component mounting device 1 as indicated by arrows C and D in the drawing, and the electronic component mounting device 1 It is connected to the front part or the rear part (an example of the rear part is not shown), and the tip of the shuttle conveying beam 17 is inserted into the electronic component supply base 9 of the electronic component mounting apparatus 1 from the tip adsorption point. Parts are supplied to the work head 15.
[0015]
FIG. 7A is a view for explaining the configuration and function of the tray-type component supply device, and FIG. 7B is a view showing a tray and a pallet accommodated therein. FIG. 7A shows an example of the tray-type component supply device 16a shown in FIG. 6A (the other 16b, 16c, and 16d are basically the same).
[0016]
As shown in FIG. 7 (a), the tray-type component supply device 16 (16a) opens the door 18 of the main body, and detachably mounts the tray shelf 20 on the internal lifting platform 19, and has a hole 21. The fastening bar 22 is inserted to the bottom and fixed on the lifting platform 19.
As shown in FIGS. 6 (a) and 6 (b), the tray-type component supply device 16 coupled to the electronic component mounting device 1 is arranged from the main body to the center of the production line as shown in FIG. 7 (a). And a desired tray 24 accommodated in a tray shelf 20 as will be described later is placed on a pallet 25 (see FIG. 7B). It is drawn together (not shown in figure (a)).
[0017]
A tray 24 is detachably mounted on the pallet 25, and a large number of electronic components 26 are mounted and accommodated on the tray 24. A hook engaging portion 25-1 is formed at the front end portion of the pallet 25, and a movable pull-out hook provided on the main body portion side engages with the hook engaging portion 25-1 so that the pallet 25 is moved. It is configured to be pulled out on the component supply stage 23.
[0018]
The electronic component 25 on the tray 24 is adsorbed by an adsorbing nozzle on the electronic component transfer head of the uniaxial robot 27 (in the figure, it is on the side opposite to the main body device 16 (diagonally left upper direction) and is not visible because it is slightly shaded). Then, it is transferred to a parts transport table (shuttle) 28 on the shuttle transport beam 17.
[0019]
On the shuttle conveyance beam 17, a conveyance path 17-1 is formed in which two component conveyance tables 28 (28 a, 28 b) reciprocate while crossing each other by a drive mechanism (not shown). The component carrying table 28 to which the electronic component 26 has been transferred carries the electronic component 26 to the suction point 29 at the tip of the shuttle carrying beam 17. The work head 15 of the electronic component mounting apparatus 1 sucks the electronic component 26 on the component carrier 28 that has reached the suction point 29 and mounts it on the substrate 8 at a predetermined position.
[0020]
Originally, such a tray-type component supply device is a component supply device that has been developed for the purpose of supplying large-sized or odd-shaped components that are difficult to supply with a tape-type component supply device. The positioning of the drawn pallet, that is, the positioning of the electronic component on the tray, should be a position that can be picked up by the electronic component transfer head of the single-axis robot.
[0021]
Then, the error due to the above-mentioned suction is performed after the picked-up electronic component is image-recognized by the component imaging camera, and based on this image recognition, the center position of the potential component and the horizontal front-back direction, that is, the rotation angle are corrected. If it is transferred to the component carrier, it is easy to accurately convey it to the suction point, and thereafter, the electronic component can be accurately sucked by the work head of the electronic component mounting apparatus.
[0022]
Therefore, the positioning of the pallet on the component supply stage may be within the allowable range of the error of the suction position of the large-sized or odd-shaped component as described above, and does not require much accuracy within the range. Then, the bottom surface of the pallet is brought into sliding contact with the two rails, and the both sides of the pallet are pulled out from the tray shelf onto the component supply stage while being guided by the guide plate with a slight play (for example, , See Patent Document 1).
[0023]
As described above, the left and right positioning of the pallet is based on the regulation by the guide plate having an interval with play (the pallet cannot be pulled out if there is no play in the interval of the guide plate). Positioning, i.e. positioning of the tray on the pallet, and hence the positioning of the electronic components on the tray, is within the tolerance of the error in the suction position of the large or deformed parts, but compared to small and more precise electronic components. Was low.
[0024]
Conventionally, as described above, for example, a small-sized electronic component having a size of about 5 mm square or less is required to be supplied by a tape-type component supply device, and a relatively large electronic component having a wide tolerance range of the suction position. Only parts and odd-shaped parts were supplied by a tray-type parts supply device.

[Problems to be solved by the invention]
However, in response to the recent demand for further downsizing of electronic devices and the increasing demand for downsizing of board units incorporated in electronic devices, electronic components mounted on board units are also as much as possible. It has become smaller and thinner.
[0027]
In particular, an electronic component called CSP (chip, size, package) is not a package component that is protected by molding by bonding an internal terminal to an external terminal such as a lead wire or a bump as in the prior art, but has an external terminal. It is a bare silicon IC with no internal mold and no internal terminals, and this is handled as an electronic component package. That is, such a bare electronic component has been mounted on a substrate as it is.
[0028]
When an electronic component package made of such a bare silicon IC is to be supplied by a tape-type component supply device, since bare silicon is an extremely fragile member, an electronic component package made of such a bare silicon IC. In the case of taping that is sandwiched between two tape members on the upper and lower sides, it is fragile and the occurrence of defects increases, which not only lowers the production efficiency on the electronic component mounting device side but also increases costs due to the occurrence of defects. A problem occurred.
[0029]
Therefore, a tray-type component supply device that places, transports, and supplies electronic components has almost no fear of breaking even an electronic component package CSP made of a bare silicon IC. It has come to be considered to use a type component supply device.
[0030]
By the way, as described above, in the conventional CSP in which the silicon IC having the finely arranged internal terminals to be bonded and the wiring terminals of the substrate are bare, the IC central portion excluding the internal terminals is extremely The area is small. Therefore, the allowable range of the error of the suction position when sucking this small area portion with the electronic component transfer head of the uniaxial robot is extremely narrow.
[0031]
However, as described above, since the positioning of the pallet on the component supply stage of the tray-type component supply device is relatively low in accuracy, high accuracy is required for positioning the pallet on the component supply stage. Otherwise, for a CSP where the tolerance range of the suction position error is extremely narrow, as a problem before the position correction is performed by image recognition after suction, a uniaxial robot is used for a CSP with low position accuracy. Adsorption by the electronic component transfer head is not possible.
[0032]
The subject of this invention is providing the tray-type components supply apparatus which performs the positioning of the pallet on a component supply stage with high precision in view of the said conventional situation.
[0033]
