Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-piece separating / sorting device for separating small pieces of a ceramic substrate, a resin substrate, and the like, which are in a solid state, and removing warped small pieces.

[0002]

2. Description of the Related Art For example, in the case of a ceramic substrate A shown in FIG. 6, in order to process the ceramic substrate A in a solid state in the next step, the ceramic substrates are separated into non-overlapping parts. In addition, it is necessary to eliminate the warped ceramic substrate A from the normal ceramic substrate A. Conventionally, the above-described separation work is performed by applying vibration to a large number of ceramic substrates A supplied to a component storage unit provided in the center of a bowl-shaped container, so that the ceramic substrate A is placed on a component transfer path extending from the component storage unit. This is performed by using a vibrating parts feeder that discharges A and transfers the individual ceramic substrates A in a fixed direction. Also,
In the separating operation, a gate that can be opened and closed is provided on the conveyor at intervals in the longitudinal direction, and the ceramic substrate A is separated by opening and closing the gate. On the other hand, the removal operation of the warped ceramic substrate A after the separation operation includes:
The ceramic substrate A is transferred to the next step through the slit gauge, and the warped ceramic substrate A anchored in the slit gauge is removed from the slit gauge and removed.

[0003]

However, such a small piece separating / sorting operation still has the following problems to be solved. That is, when a vibrating parts feeder is used for the separation operation, the equipment becomes large or the number of units increases, so that the equipment cost increases. In addition, the ceramic substrate A is agitated inside the bowl-shaped container of the parts feeder, which may cause chipping failure. In addition, since the work of removing the warped ceramic substrate A is performed manually, it requires a great deal of time and labor, and is inefficient.

The present invention has been made in view of such circumstances, and can be manufactured at a low cost with a compact structure, and automatically separates and sorts small pieces to efficiently perform separation and sorting work. It is an object of the present invention to provide a small piece separating / sorting machine capable of performing the above.

[0005]

According to the present invention, there is provided a small piece separating / sorting machine according to the present invention, which is provided with a small piece separating section for separating small pieces in a lump state into individual small pieces and a downstream side of the small piece separating section. A small-piece separating / sorting machine comprising a small-piece sorting unit for sorting and removing warped small pieces from the separated small pieces, wherein the small-piece sorting unit allows a normal small piece to pass therethrough but the warped small piece to be moored inside. A small piece inclined passage having: a small piece inclined passage, a warped small piece detection means for detecting a small piece of warpage moored in the small piece inclined passage, and a small piece discharging plate advanced into the small piece inclined passage based on a detection output of the warped small piece detection means. A small piece discharging means for discharging the warped small pieces moored in the inclined passage.
Here, the small piece refers to, for example, a ceramic substrate or a resin substrate, and the height of the small piece inclined passage is preferably the average value of the thickness of the small pieces of the population + the standardized allowable warpage amount of the warped piece. It can be.

[0006] In the above-described configuration, first, the small pieces in the solid state are separated into individual small pieces in the small piece separating section. Then, the separated small pieces are transferred to the next step through the small piece inclined passage. Here, the height of the small-piece inclined passage is set to a height at which normal small pieces are passed but warped small pieces are moored inside, so that normal small pieces can be quickly transferred to the next step. ,
The warped small pieces can be moored in the small inclined path.
Then, by detecting the warped small piece moored by the warped small piece detecting means and driving the small piece discharging means,
The warped small piece can be quickly removed from the small piece inclined passage.

Here, the small piece inclined passage is preferably formed by a lower inclined plate and an upper glass plate disposed above the lower inclined plate at a parallel interval. In this case, by using the upper glass plate, a small piece inclined passage having good smoothness can be easily formed. Further, the operator can visually check the behavior of the small piece such as the ceramic substrate in the small piece inclined passage with the naked eye.

The small piece separating section may have a cascade structure in which a plurality of vibration tables are connected in series, and may have a configuration in which a step surface is formed on the upper surface of each vibration table. In this case, by driving the vibration table, the small pieces will sequentially spread due to a synergistic effect of appropriate vibration of the vibration table and falling from the stairs when passing through the stepped plate surface, Separation will be promoted.
