Abstract

PURPOSE:To increase efficiency in a pallet for a vibratory part arraying device by arranging a vacuum supply hole to adsorb a storing part onto the bottom surface portion of the part arraying hole under vacuum. CONSTITUTION:A large number of LEDs 16 are loaded on a part arraying pallet 10 so as to be vibrated and at the same time vacuum is supplied to a vacuum supply hole portion 19 by driving a vacuum device. Thereby, the inside of an arraying hole portion 15 is put under a negative pressure condition. Thereby, the LEDs 16, which have reached onto the arraying hole portion 15 while being vibrated, is attracted to the bottom surface portion 21 of the arraying hole portion 15 under vacuum so as to be stored stably in a normal position. In this way, even if the part cannot be held deeply inside of the arraying hole due to differences in the part forms, the part can be stored stably and efficiently.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pallet for aligning components, and in particular, a pallet for aligning a large number of mounted components by applying vibration to accommodate and align a large number of mounted components within component alignment holes. Regarding pallets for arranging parts.

[Prior Art] Various vibrating component alignment devices have been used from the viewpoint of automation.

Such a conventional vibrating component alignment device includes a component alignment pallet on which a large number of components are placed and aligned, a base portion to which the component alignment pallet is fixed by an appropriate fixing means, and a base portion that is attached to the base portion. It is equipped with a fixed vibration generator.

Then, by operating the vibration generator, the generated vibration is transmitted to the alignment pallet via the base part,
By vertically or horizontally swinging the component alignment pallet, the components placed on the component alignment pallet are stored in the component alignment holes drilled in the component alignment pallet body, and the components are aligned. is configured to do so.

[Problem to be Solved by the Invention] By the way, in the case of arranging LEDs as parts, for example, as shown in FIGS. 1
When such LEDs 16 are to be aligned on a component alignment pallet using a vibrating equipment alignment device, the LED main body The terminals 17 and 17 protruding from both ends of the LED 18 become an obstacle, making it impossible to store the LED 16 while holding it deeply in each component alignment hole provided on the component alignment pallet. There is a problem that it is difficult to align the parts using a pallet.Therefore, the technical problem of the present invention is to solve the problem of the difficulty in aligning the parts using a pallet. To store components that cannot be deeply held in a component alignment hole and to efficiently align them.

[Means for Solving the Problems] In order to solve such technical problems, in the present invention, a vacuum supply hole is provided at the bottom of the component alignment hole to vacuum suck the stored components. It is something that

[Example] As shown in FIGS. 1 and 2, a plurality of component alignment holes 13 are opened at predetermined intervals in the component alignment pallet 10 according to the present embodiment.

As shown in FIGS. 2 and 5, the component alignment pallet 10 includes an alignment pallet 11 and a guide pallet 12 fixed to the upper surface of the alignment pallet 11. As shown in FIGS. These alignment pallets 11 and guide pallets 1
2 is composed of rectangular plate-shaped parts formed to have the same dimensions. In the upper half of the alignment pallet 11 in the thickness direction,
An alignment hole 15 having a predetermined size is provided, and a vacuum supply hole 19 is provided below the alignment hole 15.
Each has been established.

As shown in FIG. 3, the alignment hole portion 15 is formed to be substantially the same as the planar outline of the LED as the component to be aligned. That is, as shown in FIG. 3, the alignment hole portion 15 has a generally rectangular planar shape, and circular convex portions 20 are formed at three corners to protrude outward. The length and width of the alignment hole portion 15 are formed to be substantially the same as the length and width of the LED as the component to be aligned.

Further, the depth dimension of the alignment hole portion 15 is
16 is approximately 1/3 of the height dimension. As shown in FIGS. 8 and 9, the LED 16 consists of a main body 18 and terminals 17 and 17 protruding from both ends of the main body 18 in the longitudinal direction. , since the above terminal 17.17 becomes an obstacle,
It is impossible to ensure a sufficient depth dimension of the alignment holes 15.

Therefore, the depth of the alignment hole 15 is smaller than the height of the portion of the LED that protrudes above the alignment hole.

Then, as shown in FIG. 3, the bottom surface 2 of the alignment hole 15 is
A vacuum supply hole 19 is provided in the center of the vacuum supply hole 1 .

The vacuum supply hole 19 is formed such that one end thereof is open to the bottom surface 21 of the alignment hole section 15 and the other end thereof is open to the lower surface side of the alignment pallet 11.

On the other hand, as shown in FIGS. 5 and 6, a guide pallet 1 is attached and fixed to the upper surface of the alignment pallet 11.
2, a plurality of guide holes 14 are opened.

As shown in FIGS. 5 and 6, the upper guide hole portion 14 is formed of a circular hole portion in plan view, has a trapezoidal cross section, and is formed in a tapered shape that widens toward the upper surface of the guide pallet 12. has been done.

As shown in FIG. 1, the diameter of the lower opening 22 is larger than the length of the alignment hole 15, and the diameter of the upper opening 23 is larger than the length of the alignment hole 15. It is formed to be larger than the diameter of.

As described above, the guide pallet 12 is attached and fixed onto the alignment pallet 11 so that each guide hole 14 is appropriately positioned over each alignment hole 15 as shown in FIG. ing.

As a result, as shown in FIG. 1, the guide hole 14 opens wide above the alignment hole 15, and the LED
6 is configured to be easily accommodated in the alignment hole portion 15.

The operation of the parts alignment pallet 10 according to this embodiment will be explained below.

When aligning the LEDIs 6 as components using the component alignment pallet 10 according to the present embodiment, first, a large number of LEDIs 6 are placed on the component alignment pallet 10 according to the present embodiment. Thereafter, a vibration generator (not shown) is operated to transmit vertical vibrations to the component alignment pallet 10 according to this embodiment.

Then, the component alignment pallet 10 according to this embodiment is driven in the vertical direction, and alignment of the LEDIs 6 is started. Thereafter, vacuum is supplied to the vacuum supply hole 19 from a vacuum generator (not shown) through appropriate means.

In this case, the inside of the alignment hole 15 becomes negative pressure, and the LEDI 6 is attracted to the bottom surface 21 of the alignment hole 15 .

As a result, the depth dimension of the component alignment hole 13 is
Even if the height dimension of the LEDI 6 is smaller than the height of the upwardly projecting part of the component alignment hole 13 of the LEDI 6 housed in the LEDI 6, the bottom part of the LEDI 6 is 21 and are arranged by suction.

In addition, in this example, LE
Although the explanation is made using DI6, the present invention is not limited to this example, and when a component is stored in each component alignment hole, the height dimension of the part that protrudes above the component alignment hole is larger than the height of the component alignment hole. It is sufficient that the parts are larger than the depth dimension, and such parts can be effectively aligned using the parts alignment pallet according to this embodiment. Further, the planar shape of the alignment hole 15 needs to be changed as appropriate depending on the shape of the parts to be aligned.

[Effects of the Invention] Since the component alignment pallet according to the present invention has the above configuration, even if the components cannot be held deeply in the component alignment holes due to the shape of the components, It is possible to efficiently align the vibrating components using the vibrating component alignment device.
