It consists of 10.

The tray 20 is provided with a hooked portion 21 having a shape that can be pressed in a substantially horizontal direction by the flag 10 at a position not used for mounting an IC. The hooked portion 21 has an opening portion 21a penetrating in a substantially vertical direction, and the opening portion 2 from the tray front surface 20a to the opening portion 21a.
The cutout portion 21b is cut narrower than 1a. The opening 21a is formed in a rectangular shape in a plan view, and is provided so that its longitudinal direction is orthogonal to the drawing direction of the tray 20.

The storage rack 31 includes the tray 20 from the front side.
Is stored in a state where it can be inserted and removed. Further, tray guides 31a are provided so as to grip both ends of the tray 20 in accordance with the number of stages to be stored on both side walls of the storage rack 31. The tray guide 31a and the side wall, that is, the surface in contact with the tray 20 is subjected to a surface treatment for reducing the friction coefficient, for example, a coating treatment with a fluororesin. The elevator 32, on which the storage rack 31 is mounted, fixes the storage rack 31 by a lock mechanism (not shown), and drives the drive motor 33 in a substantially vertical direction to a predetermined height, that is, the tray 2.
The lower surface of 0 is driven so that it can be positioned at a height that is flush with the horizontal surface of the transfer rail 34a described later. The storage rack 31 and the elevator 32 are both the elevator 3
2 A relief is provided (not shown) so that the bottom portion thereof does not interfere with the flag 10 when moving up and down. Further, the tray pull-out stage 34 has a vertical surface on its upper surface, which is substantially horizontal with the lateral width of the tray 20 so as to grip near both ends of the tray 20 which is guided in a substantially horizontal direction, and a horizontal plane which supports near both ends of the tray 20. Nijo transfer rail with 3
4a is formed. A plate-shaped member made of, for example, a fluororesin material is attached to the transfer rail 34a in order to reduce the coefficient of friction with the tray 20.

The flag 10 includes two transfer rails 34.
While being guided by the slide table 13 in parallel with the transfer rail 34a, the timing belt 14
It is driven by the drive motor 15 via the and is reciprocated in a substantially horizontal direction. At this time, as the drive motor 15, for example, by using a stepping motor, the flag 1
The movement of 0 is precisely controlled in its position. The flag 10 includes a hooking portion 11 for hooking with the hooked portion 21,
It is composed of an operating rod 12 that is raised above the slide table 13. The hook portion 11 has a height corresponding to the transfer rail 34a, that is, the transfer rail 34a.
The flag 10 is provided on the upper end of the operating rod 12 in a state where the horizontal plane a and the hooking portion 11 are located on the same plane, and the front shape of the flag 10 is T-shaped. Further, the hooking portion 11 is a rectangle having the same planar shape as that of the opening portion 21a, and has the opening portion 2
1a is provided so that it can pass in a substantially vertical direction. The vertical thickness of the hooking portion 11 is smaller than the distance between the upper surface of the lower tray 20 and the lower surface of the upper tray 20 with one tray 20 interposed therebetween. On the other hand, the operating rod 12 is provided so as to have a width narrower than that of the pull-out portion 21b and pass through the pull-out portion 21b in a substantially horizontal direction. still,
Although the flag 10 in the illustrated example has a T-shaped front shape and a rectangular planar shape, the flag 10 may have an inverted L-shaped front shape or a circular or wedge planar shape. It is feasible.

Next, the operation of pulling out the tray 20 selected by the work contents on the tray pull-out stage 34 will be described. When the flag 10 is on the tray pull-out stage 34 side, that is, when the hooked portion 21 and the hooking portion 11 are not in the hooked state, the hook 10 is opened on the storage rack 31 side.
It moves to a position where it can pass inside without interference. At this time, the elevator 32 is raised to prevent it from hindering the movement of the flag 10. Then, the tray 20 selected according to the work contents is positioned by the elevator 32 to a predetermined height, that is, the lower surface of the tray 20 is flush with the horizontal surface of the transfer rail 34a. Therefore, with the elevator 32 positioned, the tray 2 to be pulled out
The opening portion 21a provided at 0 engages with the hooking portion 11.

After the positioning of the elevator 32 is completed, the flag 10 is moved to the tray pull-out stage 34 side. As a result, the hooking portion 11 presses the surface of the opening portion 21a on the tray drawing stage 34 side. Therefore, the tray 20
With the movement of the flag 10, the flag 10 is pulled out onto the tray pull-out stage 34 so as to be guided by the transfer rail 34a, and is positioned by the accurate position control of the flag 10. However, the operating rod 12 of the flag 10 passes through the removed portion 21b provided in each tray 20 without interfering with it. At the same time, the hooking portion 11 is formed such that the thickness in the vertical direction is smaller than the distance between the upper surface of the lower tray 20 and the lower surface of the upper tray 20 with the tray 20 being pulled out therebetween. Therefore, the flag 10 can pull out only the tray 20 located at a predetermined height from the plurality of trays 20 onto the tray pull-out stage 34.

At this time, the flag 10 is the transfer rail 34a.
Since the pressing point of the tray 20 is located between the support points, the rotational moment applied to the support points can be suppressed, and the tray 20 can be moved in a stable posture. Further, when the hooking portion 11 and the operating rod 12 are formed in a T-shape, it is not necessary to provide the relief of the flag 10 on the top plate of the storage rack 31, and the hooking portion 11 has the hooked portion 21.
When pressing, the tray 20 can be pulled out and stored smoothly in order to prevent uneven rotation moment applied to the operating rod 12. Furthermore, when the planar shapes of the hooking portion 11 and the opening portion 21a are rectangular, it is easy to increase the pressing area as compared with other shapes. Therefore, the surface pressure of the pressing surface is reduced, and the posture of the tray 20 when the tray 20 is moved is stably drawn out, and the reliability of storage is improved.

The tray 2 pulled out as described above
On the tray pull-out stage 34, for example, the ICs on the tray 20 are supplied to the handling robot, or the ICs are stored on the tray 20 designated by the rank of the measurement result. After the work is completed, the flag 10 is moved to the storage rack 31 side in order to store the tray 20 in the storage rack 31. At this time, the hook 11
Since the surface of the opening portion 21a on the storage rack 31 side is pressed,
The tray 20 is stored in the storage rack 31 as the flag 10 moves. Further, during the above-described work, that is, in the state where the tray 20 is pulled out onto the tray pull-out stage 34, the elevator 32 can be moved up and down, so it is possible to select the stage to be stored in the storage rack 31 depending on the result of the work. Is. Storage rack 3 for tray 20
When the other tray 20 is to be pulled out for the work after it is stored in 1, the tray 20 to be pulled out is positioned at a predetermined height by the elevator 32, and then the above-described operation is repeated.

In the above example, the case where the invention is applied to the IC characteristic measuring system has been described, but the invention can also be applied to the tray pulling device in other production facilities. For example, an assembly system in which an IC is mounted on a board can be considered. In the above example, the case where an IC, that is, a component is mounted on the tray 20 and the work of another process is performed on the tray pull-out stage 34 has been described. Can also be applied. When the hooked portion 21 is formed on the tray 20 as in this embodiment,
There is also an effect that an operator can use the hooked portion 21 as a handle.

[0019]

As described above, according to the present invention, the tray can be pulled out and stored without being clamped by the action of the operating rod of the flag, the hooking portion, and the hooked portion of the tray. Therefore, the flag, that is, the pipe to the movable part,
Wiring and the like are unnecessary, and it is possible to prevent the occurrence of device troubles caused by these. Since the tray is pulled out and stored by pressing the facing surfaces of the hooking portion and the hooked portion, reliable operation can be expected. In other words, the tray can be pulled out and stored reliably while ensuring high reliability. At the same time, since the clamp part is not necessary, the mechanism is simplified, and the device can be easily made compact.
