Description

METHOD FOR ROTATING A METERIAL IN MATERIAL PRODUCTION EQUIPMENT BACKGROUND OF THE INVENTION [0001]

The present invention relates to a method of rotating a material in a material production facility, and more particularly, to a method of rotating a material in a material production facility, which is a single independent facility for producing a predetermined material (e.g., a substrate) To a method of rotating a material in a material production facility for rotating the material in a material production facility.

Typically, automation processes for mass production are often performed continuously (e.g., inserting, inspecting, or labeling parts) while placing a workpiece on a conveyor belt and transporting it.

In the case where such a workpiece is a substrate (e.g., a printed circuit board), it usually requires a double-sided operation on the substrate. Conventionally, an operator has worked on the backside of the substrate by turning the substrate upside down on the side of the production line. The working time becomes longer and the production efficiency is lowered.

To overcome this inconvenience, a substrate reversing device has been developed for automatically reversing the substrate to continue the next operation.

However, the conventional substrate reversing device is a structure for reversing the double-sided substrate as it is positioned between two substrate production facilities for mounting parts on a substrate or performing dispensing on a processing line.

That is, after completion of the operation for mounting the components on the upper surface of the double-sided substrate by the first substrate production facility among the two substrate production facilities, the corresponding double-sided substrate is moved to the process line, Side substrate provided by the substrate reversing device being positioned is reversed by 180 占 and moved to the process line again, and the substrate reversing device is disposed on the process line through the second substrate production facility, And a component mounting operation for the lower surface.

Therefore, since the conventional substrate reversing apparatus can perform the production process for the substrate for both sides only by constructing the two substrate production facilities, the equipment cost required for the substrate production process increases, and the line length for the production process also increases The work space for producing the bar substrate needs to be secured enough to accommodate all the above-mentioned facilities. As a result, the process speed required for the substrate production process is slowed down to a certain level or less.

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

1 is a diagram of a material rotation system 100 in a material production facility according to the present invention.

As shown in FIG. 1, a material turning system 100 in a material production facility may be used to perform a corresponding production process on a material in a material production facility, which is a single, independent facility that produces a given material And a process of rotating the material at a specific point in time when the material enters the material production facility.

That is, the above-described material rotation system 100 can be implemented in a form including a rotation unit 120, a conveyor unit 110, and a control unit 130 in a material production facility.

Hereinafter, in order to describe the present invention in detail, the above-mentioned material will be described as an example, and the material production facility is also referred to as a substrate production facility.

First, the rotation unit 120 performs a function of inverting the double-sided substrate from the upper surface of the substrate to the lower surface of the substrate, or inverting from the lower surface of the substrate to the upper surface of the substrate. In some cases, the rotation unit 120 may rotate at a specific angle instead of inverting the material by 180 ° in consideration of the characteristics of the material and the operation characteristics for performing the material.

In addition, since the rotation unit 120 is required to perform a rotation function together with the production process unique to the substrate production facility such as component mounting and dispensing in the substrate production facility, And a structure corresponding to the internal structure in the substrate production facility.

Such a rotation unit 120 is not only mounted on the conveyor unit 110 in the substrate production facility but also can be easily mounted on other types of material production facilities and is not limited to a specific standard And may include a universally mountable coupling structure.

As described above, the rotation unit 120 may be additionally mounted on the conveyor unit 110 in the already-built substrate production facility, or may be integrated with the conveyor unit 110 as necessary.

That is, the rotation unit 120 may include a rotation driving pulley, a housing, and a gripper.

When the rotational driving pulley comes to a specific point in time for rotating the substrate, the power supplied from the outside may be applied to the rotation of the substrate.

The rotation drive pulley may be configured to transmit a rotational force by engaging the power provided from the outside with the belt, or alternatively may be a gear engagement structure, a CAM structure, or the like. It is also possible that the drive source is directly connected to the rotation drive pulley.

In addition, the housing of the rotation unit 120 supports the rotation drive pulley and the gripper, and is configured to transmit the rotational force transmitted from the rotation drive pulley to the gripper to finally support the accurate rotation of the substrate.

In addition, the housing of the rotation unit 120 may also be provided with a structure that transmits the driving force for forward and backward movement of the gripper to the gripper to finally support the forward or backward movement of the substrate.

Here, the driving force for advancing or retracting the gripper may be realized through pressure transmission through air or fluid, or may be implemented in such a manner that the gripper is advanced or retracted through the pressure transmission structure and the spring arrangement.

For example, when the driving force for advancing or retracting the gripper is realized through pressure transmission through air or fluid, as the pressure is increased on the pressure transmission path on which the driving force is provided, the guide shaft, which is located on the pressure transmission path, To implement the forward movement of the gripper and to reduce the pressure on the pressure transmission path provided with the driving force, the guide shaft located on the pressure transmission path can be pulled inward to implement the backward movement of the gripper.

As another example, when the driving force for advancing or retracting the gripper is implemented in the form of a combination of a pressure transmission structure through air or a fluid and a spring arrangement, the pressure in the pressure transmission path When the guide shaft is moved to the inside again, the pressure applied to the pressure transmission path is stopped, so that the end of the guide shaft The guide shaft can be moved to the inside of the housing by the repulsive force of the spring which is compressed in the gripper, thereby realizing the backward movement of the gripper.

In addition, the driving force for advancing or retracting the gripper can be performed through a separate driving means other than the structure using pressure and spring force as described above.

In addition, the housing of the rotation unit 120 has a structure for transmitting a driving force for advancing or retracting the gripper, and a structure for providing a gripper with a pressure of air or fluid capable of performing a grip operation of the gripper .

That is, the housing of the rotary part 120 includes a first housing part for supporting the forward or backward movement of the gripper while supporting the rotation of the gripper, and a first pressure transmission path for advancing or retracting the gripper, And a second housing portion for providing pressure to the second pressure transmission path for the second pressure transmission path, respectively.

A bearing for supporting the rotation of the center rotary body connected to the guide shaft and the gripper pressure supply shaft is provided inside the housing of the rotary part 120, and the gripper is moved forward or backward during the rotation of the rotary body, A rotating seal may be provided around the center rotating body so as to be smoothly performed.

The gripper is configured to fix the substrate in the process of rotating the substrate, and at least one gripper can be provided in the rotation unit 120. [

As described above, the gripper can be moved forward or backward by receiving pressure from the first pressure transmission path provided in the housing of the rotation unit 120, and the second pressure transmission path provided in the housing of the rotation unit 120 So that the grip operation can be performed.

As such, in addition to the manner in which the gripper moves or operates through pressure, it can also be implemented in a manner that moves or operates through a separate electrical or mechanical actuation actuator.

As the internal structure of the gripper is made of a pressure transmission type, the pressure of the air or fluid delivered from the second pressure transmission path is introduced into the internal central pipe, And the second cylinder rod is pushed out to the outside.

When the first cylinder rod and the second cylinder rod are interrupted or reduced in pressure to the inner central tube, the first cylinder rod and the second cylinder rod are displaced by the repulsive force of the spring mounted on the inner ends of the first cylinder rod and the second cylinder rod, 1 cylinder rod and the second cylinder rod can be drawn in.

It is also possible that a rake-pinion structure can be adopted to stably move the upper grip shaft and the lower grip shaft of the gripper at the same time to fix the grip to the substrate or release the grip to the substrate.

Conveyor portion 110, on the other hand, may include a frame, a width adjustment unit, a lane, and a dispensing unit.

Here, the dispensing unit refers to all the various sub-process units for performing the substrate production process, and may be used to include the rotation unit 120 when the rotation unit 120 described above is mounted on the conveyor unit 110 .

That is, the dispensing unit may include a belt transfer unit, a stopper unit, a rotation unit (i.e., the rotation unit 120 described above), a clamp unit, and a sensor unit.

The lanes in the substrate production apparatus can be constructed as a single lane or a plurality of lanes.

For example, in the case of dividing into two lanes, that is, a front lane and a rear lane, a substrate production process is performed on each lane, and the process is divided into a front lane and a corresponding dispensing unit and a rear lane and a dispensing unit desirable.

The width adjusting unit is a device for adjusting the frame width between the fixed lane part and the transport lane part constituting each lane according to the size of the substrate. To this end, it is provided with a structure including a conveyance guide unit, a motor, a pulley and a belt for moving the conveyance lane part to a predetermined frame width. And may further include various I / O boards, solenoid valves, sensor amplifiers, and the like.

The belt transfer unit also includes a driver, a pulley, and a belt, and serves to perform additional entry or exit of the substrate during the substrate production process.

The stopper unit stops the substrate in the working area for mounting or dispensing the substrate, or stops the substrate in the working area for rotating the substrate.

The clamp unit serves to fix or unfasten the substrate, and includes a structure in which the upper surface of the substrate is lifted up to the bottom surface of the substrate clamp cover in cooperation with the back up table.

In addition, the above-mentioned frame means a basic structure for forming the conveyor part 110, and it includes a substrate moving guide guide formation unit or a unit for guiding the moving path of the substrate, I / O boards, pressure units and so on.

Lanes can be divided into fixed lane part and feed lane part.

Here, the fixed lane part includes a substrate sensor for detecting the drawing-in and drawing-out of the substrate, a belt and motor for conveying the substrate, a substrate moving guide unit for guiding the movement of the substrate, a stopper unit for stopping the substrate at a predetermined position, A motor for adjusting the width between the rotation unit for rotation, the fixed lane part, and the transfer lane part, and may include a motor for fixing the substrate to stably perform operations on the substrate, and releasing the substrate after completion of the operation And a clamping unit.

The conveyance lane part includes a conveyance guide unit between both lane parts which is configured in a manner corresponding to the fixed lane part described above and which allows the width adjustment between the fixed lane part and the conveyance lane part to be conveyed along a predetermined path It is possible.

Fig. 2 is a view showing one embodiment of the substrate rotating system 100 shown in Fig. 1, Fig. 3 is a view showing another example of the operation of the material rotating system 100 shown in Fig. 2, 2 shows another operation example of the material rotating system 100 shown in Fig.

That is, after the substrate is introduced into the substrate production apparatus, the controller 130 performs mounting or dispensing of components on the upper surface of the substrate, and then fixes the substrate to prepare for mounting or dispensing parts on the rear surface of the substrate The clamp is released and the substrate is moved to a predetermined position as shown in Fig. 3 for rotating the substrate.

In order to rotate the substrate after the substrate is conveyed, the control unit 130 adjusts the width between the two lanes of the conveyor unit 110 for the first time after gripping the substrate, When completed, control is performed to rotate the substrate using the rotation unit 120, which has been described previously.

In addition, the controller 130 can determine the position of the substrate to be further inserted into the substrate production apparatus based on the sensor signal provided from the substrate sensor. In this case, the control unit 130 can control the processing speed of the substrate processing apparatus when performing an operation such as mounting or dispensing operation on the substrate in the substrate production apparatus and performing rotation of the substrate.

That is, since the substrate can be pulled into the substrate production apparatus continuously while performing the production process and the substrate rotation process in the substrate production apparatus, the position of the substrate to be additionally drawn is determined at a predetermined process speed It is possible to control the speed of the rotating process of the substrate in the current operation in consideration of the occurrence of an error in the processing on the additional substrate.

After the controller 130 completes the mounting and dispensing operation on the upper surface of the substrate on the single lane in the substrate production apparatus, the controller 130 performs rotation of the substrate using the rotation unit 120, The dispensing operation can be completed, and the control can be performed to draw out the completed substrate on both sides.

The above-described control method can be performed in various ways.

For example, when there are two working areas in the substrate production apparatus, mounting and dispensing operations are performed on the upper surface of the substrate when the substrate passes through the first working area, and then, The rotation of the substrate is performed using the rotation unit 120 positioned thereon, and then, when the substrate passes through the second work area, the mounting and dispensing operation with respect to the rear surface of the substrate can be performed.

As another example, in the case where one working area exists in the substrate production apparatus, when the substrate passes through the working area, after mounting and dispensing operation is performed on the top surface of the substrate, And the substrate is moved back to the above-described work area, so that the mounting and dispensing operation can be performed again on the back surface of the substrate in the above-described working area. Thereafter, the substrate is rotated again with respect to the substrate passing through the substrate rotation region, the substrate is taken out in the substrate alignment direction at the time of being drawn into the substrate production apparatus (i.e., the substrate is placed on the upper surface) It is also possible that the rotation of the substrate is not performed again for the substrate which passes through the substrate rotation region again.

FIG. 5 is a diagram illustrating an operation process of the substrate rotating system 100 shown in FIG. 1 according to an embodiment of the present invention.

As shown in FIG. 5, a method of rotating a substrate in a substrate production apparatus is introduced into a substrate production apparatus to determine whether to rotate the substrate after completion of component mounting or dispensing with respect to the substrate surface (S1).

As a result of the determination in the step S1, when the substrate rotation is required, the clamp for fixing the substrate is released (S3), and the substrate is moved to the correct position for rotating the substrate (S5).

In the step S5, if the correct position for rotating the substrate is the reverse direction of the substrate moving direction on the rail, the substrate can be moved in the reverse direction.

When the substrate is placed in the correct position for rotation, the substrate is gripped using the rotation unit 120 (S7), and the width between the fixed rail part and the transfer rail part on the rail is determined by a predetermined width (S9).

Then, when the space for rotating the substrate is secured through the expansion of the width between the fixed rail park and the transfer rail part, rotation with respect to the substrate is performed again using the rotation unit 120 (S11).

When the step S11 is completed, the extended width between the fixed rail park and the transfer rail part is returned to the original position, and then the grip on the substrate is released through the rotation part 120 (S13).

Thereafter, the rotated substrate is moved to a work area for mounting or dispensing (S15), and a work for the substrate is prepared by setting a clamp on the substrate at the time when the substrate moves to the work area (S17).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

The present invention also relates to a method of producing a material (e.g., a substrate), which is a single independent facility for producing a material (e.g., a substrate) Is not only sufficient but also practically usable because it can be practically carried out clearly.
