Insert injection is an injection molding method in which a metal insert is inserted into an injection mold and injection molding is performed to mold an insert made of a metal into an integral part of the resin article.

2. Description of the Related Art [0002] In recent years, as a robot automation system has become popular, an insert injection process has gradually been applied to a robot automation system. Such an insert injection system includes a pickup unit for picking up an insert, The insert is picked up using a robot, and the picked-up insert is inserted into the cavity of the injection mold apparatus.

Since the insert injection system automatically feeds the insert into the cavity of the injection mold apparatus, it reduces labor costs and shortens the process time. However, the insert injection system has the following disadvantages: 1) the servo robot inserts the insert into the injection mold apparatus The insert must be quickly transferred to the position where pickup is performed by the servo robot in response to the speed, and 2) the state toward the specific direction and position according to the product design when the insert is inserted into the cavity of the injection mold apparatus Two solutions for inserting inserts should be solved first.

That is, even if the insert injection molding is constituted by a robot automation system, there is a limit in that the process of arranging the supplied inserts and moving them to the injection mold apparatus quickly, and the process of aligning the positions and orientations of the inserts before insertion of the mold apparatus, This limitation leads to unnecessary labor consuming, and also delays the process time excessively, and has a disadvantage that the mold accident frequently occurs due to an insertion error into the mold apparatus.

In order to solve such a problem, various studies have been made to overcome the above-mentioned problem by arranging the seating jig having the seating groove on which the insert is seated and aligning the seating which is seated on the seating groove by the seating jig.

The insert member alignment jig disclosed in Registration Practical Utility Model No. 20-358427 (design name: insert member alignment jig) is an insert member feed tube that is formed as a straight groove by a piece feeder and on which the inserts are placed, And has the advantage that the large number of insert members can be quickly transported without providing a separate end effector.

However, since the insert member aligning jig is formed in such a manner that the insert is conveyed by the vibration of the parts feeder, when the insert member is not uniformly supplied to the insert member insertion portion, the operator must insert the insert member directly, The insert member can be applied only when the insert member is used in a smart phone or the like. However, the insert member can not be applied when the insert member has a predetermined volume and weight.

In addition, the insert member alignment jig has a problem that the operator can not solve the above-mentioned 2) problem since the operator must insert the inserts one by one into the insert member insertion portion in order to insert the supplied large number of inserts into the insert member insertion portion.

The alignment jig disclosed in Registration Practical Utility Model No. 20-407122 (design name: insert nut alignment jig) is also configured to transfer the insert nut by the pushing method like the above-described insert member alignment jig, And it has a disadvantage that it can not overcome the above 2) problems.
