In addition to these methods, there are methods to continuously perform work without interruption. there is.

In order to perform this continuous work, the supply of materials is continuous and certain processing operations for the materials are performed sequentially. As one of the ways to achieve continuity of work due to the continuous supply of materials, a turntable is used. There are prior technologies that have been utilized.

For example, Korea Patent Registration No. 10-1524033 is a portable type that can be processed at the site of installing a large flange, and the rotary arm is hinged to one side of the fixed arm of the fixed part, enabling precision processing while shortening the setting time. There is a portable large flange processing device.

In addition, Korea Patent Registration No. 10-1571068 includes a plurality of magazines in which materials are stacked to continuously supply plate-shaped work materials one by one to the work line, and a robot arm that picks up and moves materials one by one from the magazines. It is equipped with a (robot arm) and has a continuous material supply device that can reload materials into the magazine without interfering with the operation of the robot arm.

In addition, the vehicle brake pad plate can be positioned in the correct position on the turntable, which is Korean Patent Registration No. 10-1822163, and the return spring hole can be machined perpendicular to the hole processing surface of the pad plate in response to the intermittent rotation of the turntable. There is a hole processing device and hole processing method for the return spring of a vehicle brake pad plate and a hole inspection method for the return spring of a vehicle brake pad plate that can improve processing precision.

In the case of each of the above known and disclosed technologies, after the material is loaded in one direction, each processing device processes the material by rotating the turntable or picks up the processed material by a robot arm and loads new material again. The process goes through an uninterrupted series of processes, or one material is loaded into a jig located in the center of the turntable and then multiple processing processes are performed as the turntable rotates, and the material is removed when the processing is completely completed. It provides configurations that allow the process of continuously loading new material into the turntable's central jig.

In the case of using such known prior technologies, there is an advantage in that productivity can be expected to be improved through a continuous supply of materials and a predetermined processing process according to the rotation of the turntable.

However, each material goes through a processing process after rotating and stopping a turntable equipped with multiple processing devices while the material is loaded in the center of the turntable. Once the processing of the material loaded in the center of the turntable is completed, it is taken out and then processed into new material. By loading and processing, only one side or one direction of the material can be processed, making it impossible to apply to materials that require multi-faceted processing.

For example, it cannot be applied when machining of multiple surfaces, such as holes or plane machining on the front, plane, or bottom of the material is required, so the overall installation must be redone due to design modifications of the processing device and jig newly mounted on the turntable. there is.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The present invention provides a multi-axis multi-station processing device for sequentially processing the inner diameter and surface of a casting for use in automobile parts or other accessories.

For this purpose, as shown in FIG. 1, the present invention is provided with a material input unit 100 through which material is 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 arranged around the outer periphery of the turntable 200, a direction change standby unit 400 that changes the direction of the material, settles down, and maintains a standby state, and the processing unit ( A first robot arm unit 500 configured to enable extraction and loading of material from the direction change waiting unit 400, an inspection unit 600 for inspecting the processing completeness of the material, and a burr remaining in the material. A burr processing unit 700 for removal, a marking unit 800 for marking the surface of the material as needed, an inspection unit, and a second robot arm unit for extracting and loading material into the burr processing unit and the marking unit. 900), and a discharge unit 1000 for discharging the processed material.

The material input unit 100 is configured to supply material corresponding to the material to be processed to the multi-axis multi-station processing device of the present invention. The material input unit 100 can be formed using a general configuration. For example, materials can be supplied sequentially by a conveyor configuration, and depending on the shape of the material's accessories, they can be supplied using a conveyor in the form of a hanger or finger.

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

The turntable 200 is a means for easily processing the material taken out from the material input unit 100. For this purpose, a jig 220 is arranged radially at regular intervals on the upper surface of the turntable 200 at regular intervals at the outer peripheral end around the central axis 210, which rotates the turntable 200, and is positioned toward the central axis 210. .

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

That is, in the present invention, the jig 220 itself is rotated and not processed sequentially by a processing device, but the jigs 220 are radially arranged at equal intervals on the outer periphery of the turntable 200 and the turntable 200 itself is processed. Rotation occurs, and the material seated on the jig 220 is processed by each processing device of the processing unit 300 arranged in large numbers on the outside of the turntable 200.

The processing unit 300 refers to a configuration disposed on the outside of the turntable 200. This processing unit 300 is comprised of a number of processing devices. Each processing device may be composed of processing devices capable of processing such as drilling, reaming, flattening, milling, and finishing.

The processing devices of the processing unit 300 may be installed in various ways depending on the processing mode 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 rotating the turntable 200, and when processing in the processing device is completed, the turntable ( 200) rotates so that the next jig 220 is positioned in front, and then the process of machining in a stopped state can be repeated.

The direction change standby unit 400 is configured to take out the material that has been primarily processed by the processing unit 300 from the jig 220 provided on the turntable 200, change the direction, and then seat it 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 then returned to the initial position. will return. In this state, the first robot arm unit 500 takes out the primary processed material from the jig 220 and then goes through a process of seating it in a state where the direction of the material is changed toward the direction change standby unit 400. In this way, the material loaded on the jig 220 of the turntable 200 is taken out by the first robot arm unit 500 and the direction is changed and placed before going through the next processing process, which is called the direction change standby unit 400. can do.

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

Here, change of direction means, for example, that in primary machining, after various machining such as faceting, finishing, and roughing is performed on the upper surface of the material, bottom machining may be equally necessary, and during drilling or reaming processing, the relevant surface and the other surface are sequentially processed. This can be done, but in this case, the material must be loaded in a different direction on the jig 220 for processing to be possible.

If there is no configuration of the direction change standby section 400 presented in the present invention, the turntable 200 and the processing section 300 including the jig 220 with the same configuration must be separately provided to perform the work. As such, in the present invention, multifaceted processing of materials may be possible using one module.

The first robot arm unit 500 refers to a configuration that enables extraction and loading of materials from the above-described processing unit 300 to the direction change standby unit 400.

The first robot arm unit 500 serves to load the material from the material input unit 100 into the jig 220 provided on the turntable 200, and takes out the material on which primary processing has been completed from the jig 220 and directs it. A role of loading the material into the jig 220 of the turntable 200 from the direction change waiting section 400 for secondary processing and reloading it into the jig 220. And, it takes out the material on which secondary processing has been completed and loads it into the inspection unit 600.

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

This is explained in more detail.

4 to 5 are diagrams showing the jig 220, and the jig 220 is divided into areas into which four materials can be loaded. The jig 220 in the present invention is configured to load four materials, but may be configured in two locations. That is, the jig 220 is structured so that an even number of materials must be loaded.

The jig 220 is divided into a primary seating area 221 consisting of a set and a secondary seating area 222 consisting of a set.

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

The pressing part 223 can be understood as a means for safely fixing the material in the jig 220 when hole processing, that is, drilling or reaming, is performed, and the pushing part 224 is used to secure the material to the surface of the material. Since the surface of the material must be exposed during processing, such as face machining, planing, roughing, or finishing, it can be understood as a means to push and secure the material in one direction.

In this way, when the first work is started on the jig 220, which is divided into the first seating area 221 and the second seating area 222, the material is not loaded in all areas.

For example, when the first work is started, the first robot arm unit 500 takes out the material from the material input unit 100 and loads it only into the first seating area 221 of the jig 220.

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

In this way, at the time when the first work is started, the material is loaded only in the first seating area 221, without loading the secondary seating area 222, and the processing unit 300 moves as the turntable 200 rotates and stops. ) performs primary processing of the material loaded into the primary seating area 221.

Meanwhile, when the turntable 200 rotates one full rotation, it means that the primary processing of the material loaded into the primary seating area 221 is completed.

This means that no material is loaded into the secondary seating area 222 until the first rotation is performed.

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

When the material is loaded into the direction change waiting section 400, it is loaded in a state where the direction is changed by the first robot arm section 500. For example, when the upper surface of the material is loaded into the direction change waiting section 400, it is loaded in a downward direction. It means loading towards .

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

That is, after the turntable 200 makes one complete rotation, material is loaded into both the primary seating area 221 and the secondary seating area 222 of the jig 220.

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

In the present invention, the primary seating area 221 and the secondary seating area 222 are named to sequentially distinguish, but after the material for primary processing is loaded into the secondary seating area 222, the primary seating area 222 Of course, materials for secondary processing can be loaded into (221), and it is necessary to understand that they are distinguished for understanding of the present invention.

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

After the turntable 200 rotates, when the adjacent jig 220 reaches the first robot arm 500, it stops and the above-described process is repeated. The process of taking out material from the primary seating area 221 of the jig 220 as described above as the turntable 200 rotates and stops, then changing the direction and loading it into the direction change standby unit 400, the direction The process of taking out the material again from the switching standby unit 400 and loading it into the secondary seating area 222 of the jig 220 is repeated, and at the same time, each processing device of the processing unit 300 located on the outside of the turntable 200 They go through a process of sequentially processing the materials loaded in each of the first and second seating areas 221 and 222 of the jig 220.

The inspection unit 600 extracts the material from the direction change standby unit 400, loads it on the jig 220 of the turntable 200, and moves it to the outside of the turntable 200 according to the rotation of the turntable 200. Secondary processing is performed by each processing device of the processing unit 300 disposed in the process, and the processed material is re-extracted by the first robot arm unit 500, and then the processing completeness is inspected. it means.

The burr processing unit 700 is configured to remove burrs remaining in the material after the inspection from the inspection unit 600 is completed, and the marking unit 800 marks the surface of the material taken out from the burr processing unit 700. It is configured to do this.

The second robot arm unit 900 is operated by the inspection unit 600 and a burr processing unit 700 to remove burrs remaining in the material after the inspection is completed. It is configured to take out and load the material toward the marking unit 800 for marking the surface of the taken out material, and to take out the marked material from the marking unit 800 and load it toward the discharge unit 1000.

When the material secondaryly processed from the jig 220 of the turntable 200 by the first robot arm unit 500 is loaded into the inspection unit 600, the inspection unit 600 is inspected by the second robot arm unit 900. ) is taken out and loaded into the burr processing unit 700. Subsequently, the material from which burrs have been removed in the burr processing unit 700 is taken out and loaded into the marking unit 800 by the second robot arm unit 900, and the marking is completed in the marking unit 800. The material may be taken out again, loaded into the discharge unit 1000, and finally discharged.

The discharge unit 1000 refers to a configuration for discharging materials for which marking has been completed in the marking unit 800, that is, products that have been completely processed.

The processing process of the present invention having the above configuration will be sequentially described.

The processing process according to the present invention includes the material input process (S100), (S200), direction change process (S300), secondary processing process (S400), inspection process (S500), deburring process (S600), and marking process (S700). ), it can be done through the discharge process (S800).

The materials to be processed are supplied by the material input process (S100), and the jig (220) is installed at equal intervals in a radial position on the outer periphery of the turntable (200) around the central axis (210) of the turntable (200) by (S200). Materials are put into the process and undergo primary processing (S200).

The primary processing process (S200) is fixed to the outside of the turntable 200 according to the rotation of the turntable 200 in a state in which the material is loaded into the primary seating area 221 of each jig 220 of the turntable 200. This refers to the process of processing the material loaded into the primary seating area 221 of each jig 220 in each processing device of the processing unit 300.

The processing process of the above-mentioned primary processing process (S200) is explained in detail in the above description and is therefore omitted.

The direction change process (S300) processes the material loaded into the primary seating area 221 of each jig 220 of the turntable 200 by the primary processing process (S200) of the processing unit 300. When processing by the device is completed and the turntable 200 is returned to its original position, the material is taken out by the first robot arm unit 500 and then directed to the direction change standby unit 400 adjacent to the first robot arm unit 500. This refers to the process of changing direction and loading.

The secondary processing process (S400) removes the material from the direction change standby unit 400, where the material whose direction has been changed by the direction change process (S300) is loaded, and forms the first robot arm unit 500. is loaded into the secondary seating area 222 of the jig 220, and the material loaded into the secondary seating area 222 is processed by a processing unit fixed to the outside of the turntable 200 by rotation of the turntable 200. This means secondary processing by each processing device in (300).

The inspection process (S500) is a process for inspecting the presence or absence of defects in the material for which secondary processing has been completed, and the burr removal process (S600) is a process for removing burrs that have not been removed from the outside of the material for which the inspection process (S500) has been completed.
