Description

Linkage type roll-to-roll material exposure system of high-speed punching machine and application method thereof
Technical Field
The present invention relates to a high-speed punch linkage type roll-to-roll material exposure system and an application method thereof, and more particularly, to a high-speed punch linkage type roll-to-roll material exposure system and an application method thereof, which are linked to a high-speed punch for removing unnecessary parts of a flexible circuit board used as a mobile phone member and repeatedly form a fine circuit pattern on a continuous roll-shaped flexible circuit board in a very precise manner without errors, thereby enabling to perform exposure rapidly and accurately in a state of very low energy consumption rate and easily realizing mass production without generating defects.
Background
Recently, various electronic devices including mobile communication handsets (portable terminals) have been becoming smaller and lighter.
In general, a mobile phone has a small internal area (capacity), and all components used are small and light in size, and a flexible Printed Circuit Board (PCB) for mounting various necessary electronic components is mainly used, which is freely bendable so that mounting can be easily performed in a small internal area and various signals and electric power can smoothly flow. On the other hand, in the following description, the flexible circuit board may include a touch screen panel (Touch Screen Panel), a backlight Unit (BLU), a Gasket (gasset), a beauty mask, a medical band, etc., which are thin and perform a specific function.
Also, an antenna (antenna), which is an essential electronic component in a wireless device, is manufactured in a pattern forming manner on a flexible printed circuit board, and is manufactured by removing unnecessary parts by punching (pressing), and the flexible printed circuit board is formed of a roll-to-roll material according to an increase in demand, whereby mass production can be achieved, and a high-speed punching machine can be used when removing unnecessary parts other than a necessary pattern.
On the other hand, it is a very common process that a pattern to be formed on a roll-to-roll material is to be manufactured precisely by designing a predetermined pattern, and a punching process for removing unnecessary portions is performed in advance.
However, the punching process has a problem that a foreign matter is generated in the roll-to-roll material, and when such a foreign matter is subjected to an exposure process for forming a pattern on a photosensitive film, the defective rate of the pattern, which is required to be miniaturized and precisely produced, increases.
A related art which partially solves this problem is the "foreign matter screening device for punching material of high-speed punching machine" of korean patent No. 10-1968473 (2019, 04, 07).
Fig. 1 is a main configuration diagram illustrating a foreign matter screening device for a punching material of a high-speed punching machine according to an embodiment of the prior art.
As will be described in detail below with reference to the drawings, the main body 310 is provided with casters 312 at the lower end, the roll-to-roll material fed in a state where punching is completed by the material feeding unit 320 is horizontally moved by the first roller 314 and the second roller 316, the thickness sensor 332 constituting the foreign matter screening device 330 measures the thickness of the material and notifies the control unit 340, and the control unit 340 marks "NG" on the material including the foreign matter by controlling the cylinder 334.
Although the prior art has an advantage of being able to determine whether the inflowing foreign matter adheres to the roll-to-roll material, there is a problem in that only the confirmed foreign matter cannot be screened and removed.
On the other hand, in the existing flexible printed circuit board production system, since the raw material is hard (hard), there is a problem in that the pattern is easily separated, etc. when the pattern is formed on the curved surface, thereby consuming much production cost.
In addition, in the conventional metal foil antenna (MFA, metal foil antenna), since the pattern is formed using the extrusion die, it is difficult to embody a fine pattern, it takes a lot of die cost, it is difficult to realize pattern deformation, and it consumes a lot of initial development cost.
In addition, in the laser marking antenna (LMA, laser marking antenna), a laser marking and then gold plating method is adopted, and when an impact is applied due to lowering of a finished product or the like, cracks are generated in an injection molding, and at the same time, a pattern is broken.
Therefore, there is a need to develop a technique for precisely transferring a roll-to-roll material while removing foreign matters included in the roll-to-roll material, precisely exposing the roll-to-roll material for pattern printing, reducing production costs, and preventing pattern separation phenomenon from occurring on a curved surface of the material, enabling easy formation of a fine pattern, and enabling a pattern to be deformed very easily, and preventing pattern breakage even when an impact is applied due to a drop or the like.

That is, the second foreign matter removal portion 4000 rotates the roll-to-roll material 950 transferred between the two rubber rolls and removes foreign matters so as to adsorb the foreign matters adhering to the upper and lower surfaces of the roll-to-roll material 950, and thus is a second time (second stage) of removal of the foreign matters.
The third foreign matter removal portion 4500 has the same structure and the same function as the second foreign matter removal portion 4000, and thus, a description thereof will not be repeated, but a characteristic operation will be distinguished and described.
The third foreign matter removal portion 4500 removes foreign matters adhering to the upper and lower surfaces of the roll-to-roll material 950 by rotating, and thus is a third (third stage) foreign matter removal method.

As shown in fig. 3, the first pin hole guide rollers 5000 are arranged such that a plurality of roller guide pins 5010 protruding outward in the radial direction are arranged at the same interval a, and in each roller guide pin 5010, the interval a on the front end portion protruding with respect to the center axis is 9.5mm, and the front end portion of each roller guide pin 5010 is arranged and disposed so as to maintain the error at 0.05mm, and the cross section thereof is oval so as to be easily inserted into and removed from the roller guide hole 960 of the roll-to-roll material 950.
Each 13 th roll guide hole 960 of the roll-to-roll material 950 is designated as a piston pin guide hole 970.
The second pin hole guide roller 5500 has the same structure and the same function as the first pin hole guide roller 5000, and thus, a description thereof will not be repeated, but a characteristic operation will be distinguished and described.
The first roller tension unit 6000 is provided at the lower end of the first pin hole guide roller 5000 in this order, and measures and adjusts the transfer speed of the roll-to-roll material 950 transferred between the vertically arranged rollers in accordance with a corresponding control signal.
The first roller tension portion 6000 includes an upper pressing roller 6010, a lower rotating roller 6020, a roller pressing cylinder 6030, a transfer servo motor 6040, a roller pressing pressure detection sensor 6050, and a material transfer speed detection sensor 6060.
The upper pressing roller 6010 and the lower rotating roller 6020 each have a cylindrical shape as a whole with their respective rotation center axes positioned on a vertical line in the up-down direction, and their outer peripheral surfaces are in close contact with each other and rotated in directions opposite to each other by friction, and the outer peripheral portions of the respective cylindrical shapes are formed of a rubber material.
The roller pressing cylinder 6030 has a structure in which a piston rod that is extended or contracted according to a control signal corresponding to the roll-to-roll exposure control unit 8000 is connected to a rotation center shaft of the upper pressing roller 6010. The roller pressing cylinder 6030 moves the upper pressing roller 6010 downward in response to a control signal from the roll-to-roll exposure control unit 8000, thereby adjusting the pressing strength to increase the pressing strength, or moves the upper pressing roller 6010 upward, thereby adjusting the pressing strength to decrease the pressing strength.
The transfer servo motor 6040 is connected to a rotation center shaft of the lower rotation roller 6020 by a shaft, rotates the lower rotation roller 6020 in response to a control signal from the roll-to-roll exposure control unit 8000, and is configured by a servo motor that adjusts a rotation speed in response to the control signal.
Preferably, the transfer servo motor 6040 is controlled to rotate at 250 RPM.
The roll pressure detection sensor 6050 is in contact with the rotation center axis of the upper pressing roller 6010, and detects the strength of the downward pressing force of the upper pressing roller 6010 to notify the roll-to-roll exposure control unit 8000.
The material transfer speed detection sensor 6060 detects the roller guide hole 960 of the roll-to-roll material 950 from the corresponding control signal of the connected roll-to-roll exposure control section 8000, thereby detecting the transfer speed of the roll-to-roll material 950. More preferably, the material transfer speed detection sensor 6060 detects the transfer speed of the roll-to-roll material 950 by outputting an optical signal and receiving the optical signal reflected by the transfer table 2000. However, it is needless to say that a structure for detecting the transfer speed of the roll-to-roll material 950 by other means may be provided as needed.
The second roller tension portion 6500 has the same structure and the same function as the first roller tension portion 6000, and thus, a description thereof will not be repeated, but a characteristic operation will be distinguished and described.
The transfer servo motor 6040 constituting the first roller tension portion 6000 and the transfer servo motor 6040 constituting the second roller tension portion 6500 may have different rotational speeds, respectively, according to the corresponding control signals of the roll-to-roll exposure control portion 8000.
As an example, the transfer servo motor 6040 constituting the second roller tension portion 6500 is rotated so as to transfer the roll-to-roll material 950 at a speed of 1000mm per minute according to the respective control signals of the roll-to-roll exposure control portion 8000, and the transfer servo motor 6040 constituting the first roller tension portion 6000 is rotated so as to transfer the roll-to-roll material 950 at a speed of 999mm per minute according to the respective control signals of the roll-to-roll exposure control portion 8000.
The roll-to-roll exposure control unit 8000 receives and analyzes the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the first roller tension unit 6000 and the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the second roller tension unit 6500, respectively, and controls the respective transfer servomotors so that the transfer speed value detected (measured) by the material transfer speed detection sensor 6060 provided to the first roller tension unit 6000 is larger.
Therefore, the first roller tension portion 6000 transfers the roll-to-roll material 950 that is transferred in a flat state without sagging in a space between the second roller tension portion 6500.
The material exposure section 7000 is provided at the lower end of the first roller tension section 6000 and at the front end of the second roller tension section 6500, and is thus provided at the intermediate position of the transfer table 2000.
The material exposure unit 7000 stops transferring the roll-to-roll material 950 in response to the control signal, mechanically presses the roll-to-roll material 950 by pushing in the up-down direction, adheres to the main film for patterning by air suction, and patterns the surface of the roll-to-roll material 950 by driving the exposure lamp.
In this case, description and understanding are made in such a manner that a photosensitive film has been attached to the surface of the roll-to-roll material 950, and the following applies equally.
The material exposure section 7000 includes an exposure lamp 7100, a material pressing placement film 7200, a guide piston pin placement groove 7300, a placement film suction groove 7400, a material exposure guide piston pin 7500, a placement film pressing seal rubber 7600, and a master glass main film 7700.
The exposure lamp 7100 emits Ultraviolet (UV) according to a control signal corresponding to the roll-to-roll exposure control unit 8000, and light emitting diodes that generate ultraviolet light at an output of 1 watt (W) level or more are arranged so as to be spaced in a range of 0.5cm to 1cm in the horizontal-vertical direction, respectively. The light emitting diode is used, so that the power consumption is reduced.
The exposure lamp 7100 is composed of an upper exposure lamp 7102 and a lower exposure lamp 7104, and is activated for exposure in the case of manufacturing a flexible circuit board of a double-sided pattern, and is activated for exposure in the case of manufacturing a flexible circuit board of a single-sided pattern, respectively.
The upper exposure lamp 7102 and the lower exposure lamp 7104 are configured to increase or decrease the interval between them according to the respective control signals of the roll-to-roll exposure control section 8000 by a driving section not shown in the drawings, and further detailed description will be omitted since such a configuration is well known.
The material pressing film 7200 is a transparent film, and is fixedly provided in a moving state on the lower side surface of the upper exposure lamp 7102 adjacent to the upper side surface of the roll-to-roll material 950, so that the roll-to-roll material 950 can be pressed and fixed from the upper side surface.
A guide piston pin placing groove 7300 is formed along the circumference of the upper exposure lamp 7102, and an insertion material exposes the guide piston pin 7500 to be placed in a non-moving manner.
The set film suction groove 7400 is formed in a groove shape provided around the lower exposure lamp 7104 and connected, and forcibly sucks the adjacent object by external suction (suction). The set film suction groove 7400 strongly clings the roll-to-roll material 950 located therebetween to the upper side of the lower exposure lamp 7104 in the process of pressing the set film 7200 by the strong suction material.
The material exposure guide piston pin 7500 is formed along the periphery of the lower exposure lamp 7104, is disposed on the outer periphery of the position where the film suction groove 7400 is placed, and has a pin structure connected to a piston rod that moves in the up-down direction in response to a control signal from the roll-to-roll exposure control unit 8000.
The plurality of pins constituting the material exposure guide piston pin 7500 are inserted into the piston pin guide hole 970, respectively.
When the pin of the material exposure guide wrist pin 7500 is inserted into the wrist pin guide hole 970, the roll-to-roll exposure control unit 8000 outputs a corresponding control signal to control the upper exposure lamp 7102 to slightly move upward, thereby facilitating the insertion.
When the pattern is exposed by transferring the roll-to-roll material 950 to the position of the material exposing portion 7000, if the roller cylinders 6030 constituting the both sides in the width direction of the first roller tension portion 6000 and the roller cylinders 6030 constituting the both sides in the width direction of the second roller tension portion 6500 are moved upward, the upper pressing roller 6010 constituting the first roller tension portion 6000 and the upper pressing roller 6010 constituting the second roller tension portion 6500 are moved upward.
In this case, the lower rotating roller 6020 constituting the first roller tension portion 6000 and the lower rotating roller 6020 constituting the second roller tension portion 6500 are released from being pressed, and the surface made of the rubber material slightly moves upward.
That is, the lower rotating roller 6020 of the first roller tension 6000 and the lower rotating roller 6020 of the second roller tension 6500 are restored while the upper pressing roller 6010 constituting the first roller tension 6000 and the upper pressing roller 6010 constituting the second roller tension 6500 are moved upward, respectively. In this case, the roll-to-roll material 950 interposed (disposed) between the respective upper pressing roller 6010 and lower rotating roller 6020 will be lifted slightly upward, and the insertion can be performed quickly and accurately as the corresponding pin of the material exposure guide piston pin 7500 is made to easily find the piston pin guide hole 970 of the roll-to-roll material 950.
The first and second roller tension portions 6000 and 6500 are controlled and monitored in such a manner that the respective pins of the material exposure guide piston pin 7500 are accurately inserted into the piston pin guide holes 970 of the roll-to-roll material 950 in the range of 0.1 seconds to 0.5 seconds according to the respective control signals of the roll-to-roll exposure control portion 8000, and preferably, the respective roller pressing cylinders 6030 provided to the first and second roller tension portions 6000 and 6500 are controlled in such a manner as to be inserted in the time of 0.2 seconds.
On the other hand, when the roll-to-roll exposure control unit 8000 determines that the corresponding pin of the material exposure guide piston pin 7500 is accurately inserted into the piston pin guide hole 970 of the roll-to-roll material 950 or the set time elapses, the corresponding control signal is output to the corresponding roller pressing cylinder 6030 provided to the first roller tension unit 6000 and the second roller tension unit 6500, respectively, to move the upper pressing roller 6010 provided to the first roller tension unit 6000 and the second roller tension unit 6500, respectively, downward.
A set film pressing seal rubber 7600 is formed along the periphery of the lower exposure lamp 7104, provided in a space between the set film suction groove 7400 and the material exposure guide piston pin 7500.
The set film pressing seal rubber 7600 seals the roll-to-roll material 950 against the material pressing set film 7200 so that the suction force sucked into the set film suction groove 7400 does not leak to the outside.
The master glass master 7700 is disposed in close contact with the upper surface of the lower exposure lamp 7104, and functions as a master film having a master pattern formed thereon based on the same circuit pattern as that to be formed on the roll-to-roll material 950, and is formed of glass.
If the circuit pattern to be formed on the roll-to-roll material 950 is changed, the original glass main film 7700 can be replaced.
The master glass film 7700 may be additionally provided on the lower surface of the upper exposure lamp 7102, if necessary.
When the roll-to-roll material 950 is fed in according to the control signal of the roll-to-roll exposure control unit 8000, the material exposure unit 7000 fixes the roll-to-roll material 950 so as not to move by inserting the material exposure guide piston pin 7500 into the piston pin guide hole 970, and the upper exposure lamp 7102 and the lower exposure lamp 7104 are brought into contact to force the set film suction groove 7400 to suck the material and press the set film 7200, so that the roll-to-roll material 950 and the master glass main film 7700 are closely contacted with each other in a state of no gap, and in this case, when the exposure lamp 7100 is turned on, a very fine circuit pattern to be formed is formed on the roll-to-roll material 950 in a very precise manner without an error.
When it is determined that the roll-to-roll material 950 entered for pattern exposure has entered the material exposure unit 7000 by the roll-to-roll exposure control unit 8000 and precisely reached the corresponding position, the material exposure guide piston pin 7500 moves the pins upward by driving the corresponding pistons in response to the corresponding control signal of the roll-to-roll exposure control unit 8000, and the upward movement is maintained until the exposure step is completed. On the other hand, when the roll-to-roll exposure control unit 8000 determines that the exposure step is completed, the roll-to-roll exposure control unit 8000 drives the corresponding pin to return to the lower position by controlling the material exposure guide piston pin 7500.
The exposure lamp 7100 may be disposed to emit light to one of the upper and lower faces of the roll-to-roll material 950 or may be disposed to emit light to both faces simultaneously.
The material exposure section 7000 is inserted into a plurality of pin guide holes 970 formed in both side surface portions of the roll-to-roll material 950 in the infrared exposure process by material exposure guide pins 7500 for making the roll-to-roll material 950 to be entered and printed with a pattern immovable, and the material exposure guide pins 7500 are driven according to corresponding control signals of the roll-to-roll exposure control section 8000.
The material exposure unit 7000 forms a fine and precise circuit pattern to be printed on the roll-to-roll material 950 on the master glass main film 7700, and when the roll-to-roll material 950 enters, the circuit pattern is brought into close contact with the pattern, and the set film suction groove 7400 is driven in accordance with a control signal corresponding to the roll-to-roll exposure control unit 8000, so that the roll-to-roll material 950 and the master glass main film 7700 are brought into close contact with each other in a state free from a gap.
The roll-to-roll exposure control unit 8000 is provided at a part of the lower side of the transfer table 2000, contacts with each of the functional units constituting the system, and outputs a corresponding control signal by driving an operation program, thereby monitoring the operation state.
The roll-to-roll exposure control section 8000 may be driven alone by an operation program or by a corresponding control instruction signal input from the outside.
On the other hand, the roll-to-roll exposure control unit 8000 monitors and controls the transfer speed of the roll-to-roll material 950 by the first roll tension unit 6000 to be slower than the transfer speed of the roll-to-roll material 950 by the second roll tension unit 6500. The transfer speed is adjusted by adjusting the pressing force applied by the first roller tension unit 6000 and the second roller tension unit 6500. The function of the roll-to-roll exposure control unit 8000 may also be described in more detail in the method description section.
The camera sealing cabinet 9000 houses and seals the entire high-speed punch-linkage type roll-to-roll exposure system 900, and blocks light from flowing from outside to inside, and forcibly flows outside air into inside by a filter treatment, as shown in detail in fig. 8 of the drawings. On the other hand, a darkroom lamp for performing work is provided in the darkroom cabinet 9000, and a fan (fan) for blowing air into the interior and a high-efficiency particulate air filter for blocking fine foreign substances from the exterior are provided on the upper side surface of the exterior. Fans and high efficiency particulate air filters for blocking fine substances and foreign substances are well known, and further detailed description will be omitted.
Fig. 9 is a flowchart of a method of applying the high-speed punch linkage type roll-to-roll material exposure system according to an embodiment of the present invention, and fig. 10 is a diagram showing an antenna pattern formation roll-to-roll material after an exposure process through an etching process and other processes according to an embodiment of the present invention.
In the following, referring to the drawings, in the method of applying the high-speed punch-linkage type roll-to-roll exposure system 900 including the unwind guide table 1000, the transfer table 2000, the first foreign matter removal unit 3000, the second foreign matter removal unit 4000, the first pin hole guide roller 5000, the first roller tension unit 6000, the material exposure unit 7000, the second roller tension unit 6500, the second pin hole guide roller 5500, and the third foreign matter removal unit 4500, which are provided in this order, the roll-to-roll exposure control unit 8000 determines whether or not a corresponding signal or a command signal for performing exposure processing on the roll-to-roll material 950 is input (step S100).
When it is determined by the roll-to-roll exposure control unit 8000 that the command signal for exposing the roll-to-roll material 950 is input (step S100), the first pinhole guide roller 5000 is driven to horizontally transfer the roll-to-roll material 950 along the transfer table 2000 (step S110).
On the other hand, the roll-to-roll exposure control unit 8000 drives the first foreign matter removal unit 3000 to remove the foreign matter for the first time (first stage) (step S120).
In this case, the second foreign matter removal portion 4000 removes the foreign matter manually and physically for the second time (second stage), and the third foreign matter removal portion 4500 removes the foreign matter manually and physically for the third time (third stage). That is, there is an advantage in that foreign matter on the surface of the roll-to-roll material 950 is removed through three stages.
The roll-to-roll exposure control unit 8000 analyzes the transfer speeds of the roll-to-roll material 950 measured by the first roll tension unit 6000 and the second roll tension unit 6500, respectively (step S130).
The roll-to-roll exposure control unit 8000 determines whether the transfer speed of the second roller tension unit 6500 is faster or slower than the transfer speed of the first roller tension unit 6000 (step S140).
If it is determined by the roll-to-roll exposure control unit 8000 that the transfer speed of the second roller tension portion 6500 is lower than the transfer speed of the first roller tension portion 6000 (step S140), the pressure (push pressure) of the first roller tension portion 6000 is set so as to be lower than the pressure of the second roller tension portion 6500 (step S150).
That is, the transfer speed of the first roller tension portion 6000 is reduced, and the transfer speed of the second roller tension portion 6500 is increased. The transfer speed is a speed at which the roll-to-roll material 950 is transferred.
As an example, it is preferable that the transfer speed of the first roller tension portion 6000 is set to 999m/m and the transfer speed of the second roller tension portion 6500 is set to 1000m/m, so that the roll-to-roll material 950 is flatly unwound in a state of not being depressed inside the self-contained exposure portion 7000.
The roll-to-roll exposure control unit 8000 determines whether the transfer speed of the second roller tension portion 6500 is lower or higher than the transfer speed of the first roller tension portion 6000 (step S160). After the determination (step S160), if the transfer speed of the second roller tension portion 6500 is lower than the transfer speed of the first roller tension portion 6000, the process returns to the repetition of the above step S150, and if it is determined that the transfer speed of the second roller tension portion 6500 is higher than the transfer speed of the first roller tension portion 6000, the following steps are performed.
When it is determined by the roll-to-roll exposure control unit 8000 that a control signal for exposing a pattern to the roll-to-roll material 950 is input (step S170), the first pin hole guide roller 5000 and the second pin hole guide roller 5500 are controlled to interrupt the transfer of the roll-to-roll material 950, and the fixing pins provided in the material exposure unit 7000 are driven together to set the material to not move the roll-to-roll material 950. The roll-to-roll exposure control unit 8000 presses a portion of the material exposure unit 7000 located on the upper surface and the lower surface against the roll-to-roll material 950, thereby pressing the roll-to-roll material 950 against the surface on which the pattern is formed, and precisely adheres the roll-to-roll material 950 to the pattern by air suction as in a vacuum state. In this case, the roll-to-roll exposure control unit 8000 drives the exposure lamp 7100 provided in the material exposure unit 7000, and thus precisely exposes the pattern of the master glass main film 7700 as a photosensitive film printed on the roll-to-roll material 950 (step S180).
On the other hand, if the roll-to-roll exposure control unit 8000 determines that the exposure of the material is continued (step S190), the process returns to the material transfer step (step S110), and if the exposure is not continued, the process ends.
The following description will be made in detail with reference to fig. 10, which shows a high-speed punch linkage type roll-to-roll material exposure system and an application method thereof according to the present invention, and shows a state in which a high-speed punched roll-to-roll material 950 after an exposure process is subjected to commonly known etching and other processes, although not illustrated or described, to form an antenna pattern. A plurality of holes are continuously formed at equal intervals on a straight line of both side edge portions of the roll-to-roll material 950, and the respective pins of the first pin hole guide roller 5000 and the second pin hole guide roller 5500 are inserted into the holes and transferred at a predetermined speed. The pattern printed by exposure was very fine and delicate, but it was confirmed that each was very clearly divided and clearly formed.
The structure can screen out foreign matters in the roll-to-roll material and remove the foreign matters, precisely transfer the roll-to-roll material and accurately realize the exposure of the printed patterns on the roll-to-roll material, reduce the production cost, generate no pattern separation phenomenon on the curved surface of the material, easily form fine patterns, lead the patterns to be very easy to deform, and prevent the patterns from being broken even if the patterns are impacted due to descending and the like.
The above-described specific examples of the present invention have been described in detail, and it is apparent to those skilled in the art that various modifications and variations can be made within the scope of the technical spirit of the present invention, and such modifications and variations are within the scope of the invention as claimed in the claims.
