The present invention relates to a device for loading a component, and more particularly, to an apparatus suitable for loading a micro component such as a cathode component of a CRT assembly. Therefore, in the following description, cathode production will be described as a main background technique.

The cathode for emitting electrons to form an electron beam of the electron gun assembly is only within a few millimeters in diameter, but has a plurality of sleeves and holder ribbons. And it is a complex assembly combined with a heater (heater). Therefore, the components are so small that manual manufacturing is almost impossible and there are many difficulties in automatic manufacturing.

Shown in FIG. 1 is a configuration of a welding system for micro parts such as welding a holder to a sleeve of a cathode. For example, a support head H, on which a component P to be welded, such as a holder, is supported, is arranged on an index table T and circulates through a plurality of working positions according to its rotation. The indexing device I is configured to perform an ordinary manufacturing operation. At least one working position (loading position) of the indexing device I is provided with a loading device such that the component P to be welded is loaded onto the support head H.

The loading device is connected to a bowl feeder (not shown) and moves between the outlet side of the line feeder (F) and the support head (H) to feed the parts (P) in alignment, and the parts (P). It is comprised by the transfer machine 11 which conveys a feedstock. The conventional transfer machine 11 is provided with a manipulator 13 which can move forward and backward and move on and on the movable guide rail 12 so that the manipulator 13 is advanced and is one part from the line feeder F exit. After grasping (P), it retracts and moves along the guide rail 12 onto the support head (H), and the guide rail 12 descends to retreat after holding the component (P) and retracts the guide rail (12). Thus, the moving of the manipulator 13 is repeated when the guide rail 12 is lowered and the guide rail 12 is lowered and the part P is seated on the support head H, thereby loading the part P. Will be performed.

As can be seen from the above, the conventional loading device has a problem that the structure and the control are very complicated and the manufacturing cost is high because it is composed of the transfer machine 11 which performs a very complicated operation precisely. In addition, since the component P is very small, it is difficult for the manipulator 13 to hold it properly, so that the loading failure is frequent, and there is also a problem of lowering the operation rate of the system.

The present invention aims to provide a loading device that is simple in configuration and reliable in view of these problems.

In order to achieve the above object, the component loading apparatus according to the present invention is characterized by transporting the components by vacuum suction (眞 空 이송 着) to the transfer block for linear reciprocating motion between the outlet of the line feeder and the support head of the index device.

According to a preferred feature of the present invention, a pusher is provided on the support head to push the transported component onto the support head.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3, on the index table T of the indexing apparatus S, a plurality of support heads H, which support and circulate the components P between a plurality of working positions, are arranged in plurality, A plurality of positions are set as the loading positions, and the loading device 1 is installed therein. The present invention loading device 1 comprises a transfer block 2 which reciprocates between the outlet of the line feeder F and the support head H by the actuator 7. The transfer block 2 is formed with an accommodating groove 3 for accommodating one component P, and an adsorption hole 4 is formed inside the accommodating groove 3 to form a negative pressure source (not shown). It is connected by a flexible negative pressure hose (5), and the middle valve of the negative pressure hose (5) is provided with a zero valve (6), such as a solenoid valve (solenoid valve).

The stroke of the actuator 7 is in a state where the receiving grooves 3 of the transfer block 2 are respectively matched between the support heads H of the outlet of the line feeder F, that is, the gripping position and the falling position at both ends. In addition, the control valve 6 together with the control valve 6 operates at a predetermined timing.

On the other hand, the component P supported by the receiving groove 3 may be configured to fall and settle down by its own weight at the dropping position on the support head H. However, the pusher shown in FIG. It is preferable to further provide 8). The pusher 8 is a push pin (10) installed in the actuator (9) to push the component (P) supported in the receiving groove (3) of the transfer block 2 onto the support head (H). It will play a role.

In addition, although not shown separately, it is preferable that a guide means such as a guide rail for reciprocating the transfer block 2 is provided.

The operation of the present invention loading device of such a configuration is as follows.

First, when the control valve 6 is opened at the gripping position where the receiving groove 3 of the transfer block 2 is matched to the outlet of the line feeder F, the negative pressure is supplied to the suction hole 4 through the negative pressure hose 5. One component P of the line peter F is sucked and supported in the receiving groove 3. Next, the actuator 7 is extended to push the transfer block 2 so that the component P supported by the receiving groove 3 is matched to the drop position on the support head H on the index table T. The actuator 9 of the pusher 8 is then stretched so that the push pin 10 pushes the component P to rest on the support head H.

Each actuator 7, 9 is then retracted so that the loading device 1 returns to its initial state and repeats this operation, resulting in the continuous loading of the parts P.

As can be seen from the above, the present invention can perform the function of the conventional precision transfer machine by simply constructing a simple mechanism that performs linear reciprocating motion. Will not be.

Accordingly, the present invention has the effect of improving the productivity of manufacturing the assembly of the micro parts, such as the cathode of the electron gun assembly, and reduce the manufacturing cost.
