The present invention provides a multi-axis multi-station processing device for sequentially processing the inner diameter and surface of a cast product to be used by applying to automobile parts or other parts.

As shown in FIG. 1, the present invention for this purpose is provided with a material input unit 100 to which materials are supplied, and a plurality of jigs 220 for loading the material taken out from the material input unit 100 for processing. A turntable 200, a plurality of processing units 300 disposed on the outer periphery of the turntable 200, a direction change standby unit 400 that changes the direction of the material and maintains a standby state by seating, the processing unit ( 300) to the direction change waiting unit 400, the first robot arm 500 configured to take out and load the material, the inspection unit 600 to inspect the processing completeness of the material, and the burr remaining in the material A burr processing unit 700 for removal, a marking unit 800 for marking the surface of a material as necessary, a second robot arm unit for taking out and loading materials into the inspection unit and the burr processing unit and marking unit side ( 900), and a discharge unit 1000 for discharging the processed material.

The material input unit 100 is a configuration for supplying a material corresponding to a material to be processed to the side of the multi-axis multi-station processing apparatus of the present invention. Material input unit 100 may be made by a general configuration. For example, the material may be sequentially supplied by the conveyor configuration, and may be supplied using a hanger or finger-type conveying means according to the shape of the accessory of the material.

The configuration of the material input unit 100, the transfer method, and the transfer means include all that can be changed by those skilled in the art.

The turntable 200 is a means for facilitating processing of the material taken out from the material input unit 100 . To this end, on the upper surface of the turntable 200, jigs 220 are arranged radially at regular intervals at the outer circumferential end around the central axis 210 that rotates the turntable 200, and directed toward the central axis 210. .

In the present invention, while the material taken out from the material input unit 100 is seated on the jig 220 and rotated by the turntable 200, the rotation of the turntable 200 in a predetermined processing device disposed in the processing unit 300 to be described later In this stopped state, the process of processing the material seated on the jig 220 is repeatedly performed.

That is, in the present invention, the jig 220 itself is not rotated and sequentially processed by a processing device, but the turntable 200 itself in a state where the jigs 220 are radially arranged at equal intervals on the outer periphery of the turntable 200. The rotation is made, and the material seated on the jig 220 is processed by each processing device of the processing unit 300 arranged in plurality on the outer edge of the turntable 200 .

The processing unit 300 means a configuration disposed outside the turntable 200 . Such processing unit 300 is composed of a plurality of processing devices. Each of the processing devices may be formed of processing devices capable of processing such as drilling, reaming, leveling, milling, and finishing.

The processing devices of the processing unit 300 may be variously changed and installed according to the processing aspect of the material to be processed.

Each processing device of the processing unit 300 processes the material seated on the jig 220 located in front of each processing device by the rotation of the turntable 200, and when processing in the processing device is completed, the turntable ( 200) may be rotated so that the next jig 220 is positioned forward, and then the process of machining in a stopped state may be repeated.

The direction change waiting unit 400 takes out the material primarily processed by the processing unit 300 from the jig 220 provided on the turntable 200, changes the direction, and then settles to maintain the standby state means

While the turntable 200 equipped with the jig 220 on which the material is seated rotates once, the material seated on each jig 220 is first processed by each processing device of the processing unit 300 and returns to the initial position will come back In this state, the first robot arm unit 500 takes out the primarily processed material from the jig 220 and then places the material in a state where the direction of the material is changed to the direction change standby unit 400. In this way, a configuration in which the material loaded into the jig 220 of the turntable 200 is taken out by the first robot arm unit 500, and the direction is changed and seated before going through the next processing process is referred to as the direction change waiting unit 400. can do.

The direction change waiting unit 400 may be formed in the form of a jig.

Here, the change of direction means that, for example, in the primary machining, various machining such as face grinding, finishing, and roughing of the upper surface of the material may be performed, and then the bottom surface machining may be equally necessary, and during drilling or reaming, the corresponding surface and the other surface are sequentially It can be made, in this case, the material must be loaded in different directions on the jig 220 to be processed.

If there is no configuration of the direction change standby unit 400 presented in the present invention, the turntable 200 including the jig 220 having the same configuration and the processing unit 300 are separately provided to perform the work There is, in the present invention, multi-faceted processing of materials may be possible using one module.

The first robot arm unit 500 means a configuration that allows material to be taken out and loaded from the processing unit 300 to the direction change standby unit 400 .

The first robot arm unit 500 serves to load materials from the material input unit 100 into the jig 220 provided on the turntable 200, and takes out the primary processed material from the jig 220 in the direction The role of loading the waiting part 400 for change, and the role of taking out the material from the waiting part 400 for secondary processing and reloading the material into the jig 220 of the turntable 200. And, it serves to take out the material on which the secondary processing is completed and load it to the inspection unit 600 side.

In the process of taking out and loading the material loaded into the jig 220 of the direction change standby unit 400, the first robot arm unit 500, and the turntable 200, the area where the material is loaded into the jig 220 is different depending on the primary processing and the secondary processing.

Explain this in more detail.

4 and 5 are diagrams showing the jig 220, and the jig 220 is divided into areas into which four materials can be loaded. Although the jig 220 in the present invention is configured to be loaded with four materials, it may be made in two places. That is, the jig 220 has a structure in which an even number of materials must be loaded.

The jig 220 is divided into a first seating area 221 made of one set and a second seating area 222 made of one set.

A pressing part 223 for gripping a material is formed in one area of the primary seating area 221 or the second seating area 222, and a pushing part 224 for pushing the material is formed in the other area.

The pressing part 223 can be understood as a means for safely fixing the material in the jig 220 when drilling or reaming of the material is to be performed, and the pushing part 224 is the surface of the material. It can be understood as a means for pushing and fixing the material in one direction because the surface of the material must be exposed during machining, that is, face grinding, planing, roughing, or finishing.

In this way, when the first work is started on the jig 220 divided into the primary seating area 221 and the secondary seating area 222, no material is loaded in all areas.

For example, at the time when the first operation starts, the first robot arm 500 takes out the material from the material input unit 100 and loads it only in the primary seating area 221 of the jig 220.

Subsequently, the turntable 200 rotates, and when another adjacent jig 220 reaches the first robot arm 500, another material is taken out from the material input unit 100 again, and the first of the other jig 220 It is loaded into the seating area 221 .

In this way, at the time when the first operation is started, the material is loaded only in the primary seating area 221 in a state where the material is not loaded in the secondary seating area 222, and the processing unit 300 is rotated and stopped according to the turntable 200. ) is the primary processing of the material loaded in the primary seating area 221.

On the other hand, when the turntable 200 is completely rotated once, it means that the primary processing of the material loaded in the primary seating area 221 is completed.

This means that no material is loaded in the secondary seating area 222 until the point at which one rotation is made.

When the first rotation of the turntable 200 is performed, it means that the first processing of the material loaded in the first seating area 221 of the jig 220 is completed, and the turntable 200 returned to the initial position. The material processed primarily in the primary seating area 221 of the jig 220 is taken out by the first robot arm 500 and then loaded into the direction change waiting unit 400 .

When the material is loaded into the direction change standby unit 400, it is loaded in a state in which the direction is changed by the first robot arm unit 500. For example, when the upper surface of the material is loaded into the direction change standby unit 400, it is loaded in a downward direction. means that it is directed to and loaded.

Next, the first robot loads the new material from the material input unit 100 into the primary seating area 221 of the jig 220, and transfers the loaded material to the direction change standby unit 400 in a changed state. After being taken out by the arm unit 500, a process of loading into the secondary seating area 222 of the jig 220 is performed.

That is, after the turntable 200 has completely rotated once, materials are loaded in both the primary seating area 221 and the secondary seating area 222 of the jig 220 .

At this time, the primary seating area 221 is the material initially loaded for primary processing, and the material to be seated in the secondary seating area 222 is waiting in the direction change waiting unit 400 after the primary processing is completed. should be understood as

In the present invention, the first seating area 221 and the second seating area 222 are named in order to distinguish them sequentially, but after the material for the first processing is loaded into the second seating area 222, the first seating area It is necessary to understand that materials for secondary processing can be loaded in 221, as well as being classified for the understanding of the present invention.

In this way, the first rotation of the turntable 200 is performed and the process of taking out the material loaded in the first seating area 221 of the jig 220, and taking out new material from the material input unit 100 to make the jig 220 The process of newly loading into the primary seating area 221 remaining as an empty area of ) and the primary processed material taken out from the primary seating area 221 is taken out again by the first robot arm 500 When the process of loading into the secondary seating area 222 of the jig 220 is completed, the turntable 200 rotates around the central axis again.

When the adjacent jig 220 reaches the first robot arm 500 after the rotation of the turntable 200, the above-described process is repeated after stopping. As the turntable 200 rotates and stops, as described above, the process of taking out the material from the primary seating area 221 of the jig 220, changing the direction, and loading the material into the direction change waiting unit 400, the direction Each processing device of the processing unit 300 located outside the turntable 200 is repeated while the process of taking out the material from the waiting unit 400 and loading it into the secondary seating area 222 of the jig 220 is repeated. The materials loaded in each of the first seating area 221 and the second seating area 222 of the jig 220 are sequentially processed.

The inspection unit 600 takes out the material from the direction change standby unit 400 and loads the material on the jig 220 of the turntable 200 according to the rotation of the turntable 200 outside the turntable 200. Secondary processing is performed by each processing device of the above-mentioned processing unit 300 disposed in the above-described first robot arm unit 500 to take out the material that has been processed again, and then to inspect the processing completeness. it means.
