Description

Technical Field

[0001] This invention relates to a sliding device and testing system for durability testing of flexible materials. More specifically, the invention relates to a sliding device and testing system for durability testing of flexible materials, wherein the sliding device is configured such that, when a folding test is performed on the flexible material, a folding unit performs inward and outward folding operations on the flexible material based on the unfolded state, and performs a sliding operation in the folded state, thereby changing the position of the bent portion formed in the flexible material. Background Technology

[0002] Typically, known display panels used in monitors such as television screens or computer monitors, or various portable electronic devices, have a flat structure due to the use of non-flexible glass substrates. Therefore, known display panels are monotonous and have limited applications.

[0003] Therefore, and due to advancements in science and technology, display panels utilize flexible materials such as plastics, leading to the development and production of so-called flexible display devices. For example, flexible display panel technology has been developed, in which flexible materials can be folded or rolled up like a scroll.

[0004] For example, U.S. Patent Application Publication No. US2014 / 0247544 (Roll-up Flexible Device for Display) discloses a technique in which a flexible display component is wound around a roller inside a housing by using a rod assembly that interconnects multiple rotatable X-shaped rods.

[0005] Thin-film transistor liquid crystal displays, organic electroluminescence, and electrophoresis are used as display elements in flexible display devices of various shapes. Since the durability of the materials used in these display elements (hereinafter referred to as flexible materials) is directly related to the product's lifespan, durability testing of the selected materials is generally required before product design.

[0006] As part of the aforementioned durability testing, various tests were conducted, including a folding test. A folding test is a test of a flexible material by repeatedly bending and unfolding it. For example, a device that mechanically rotates a rotating plate is also used in the folding test, where a portion of the flexible material sample is fixed by a stationary plate, and the remaining portion of the sample is fixed by the rotating plate.

[0007] However, accurate folding tests cannot be performed using the folding devices described above. This is because it's impossible to prevent tension from acting on the flexible material when the rotating plate is rotating. Since a pure bending operation cannot be performed solely on the flexible material, the reliability of the folding test is significantly reduced.

[0008] As related technologies, Korean Patent No. 10-1349789 (title: Test apparatus for bending flexible circuit boards) and Korean Patent Application Publication No. 10-2016-0087143 (title: Folding durability testing equipment for solar cell modules) are disclosed. Summary of the Invention

[0010] This invention addresses the aforementioned problems in the prior art. The purpose of this invention is to provide a sliding device and testing system for testing the durability of flexible materials. The sliding device is configured such that, when a folding test is performed on a flexible material, a folding unit performs inward and outward folding operations on the flexible material based on the unfolded state, and performs a sliding operation to change the position of the bent portion formed in the flexible material in the folded state.

[0012] To achieve the above objectives, according to one aspect of the present invention, a sliding device for testing the durability of flexible materials includes: a base unit having a through-formed folding space; a sliding unit configured to fix one side of the flexible material to be tested and connected to the base unit for slidable movement; and a folding unit configured to fix the other side of the flexible material and arranged spaced apart from the sliding unit, and configured to rotate about the sliding unit to fold the flexible material inward or outward in an unfolded state, wherein when the sliding unit slidably moves on the base unit, the flexible material is in an inward folded state or an outward folded state, and the sliding unit can be configured to change the position of the bent portion formed in the flexible material.

[0013] The sliding unit may include: a slide rail formed on the base unit along the longitudinal direction of the base unit; a slider slidably connected to the slide rail; and a clamping member connected to the slider and configured to fix one side of the flexible material.

[0014] The sliding unit may include: a sliding motor configured to generate rotational force; and a sliding change unit configured to move the sliding member by the rotational force of the sliding motor.

[0015] The sliding unit may further include: a connecting bracket disposed on the slider to face the sliding change portion, and detachably connected to the sliding change portion.

[0016] The folding unit may include: a moving unit arranged spaced apart from the sliding unit to form the same plane as the sliding unit in the unfolded state and configured to fix the other side of the flexible material; a motion guide unit configured to form a rotation path for the moving unit to rotate the moving unit at a position between the sliding unit and the moving unit; and a motion unit connecting the motion guide unit to the moving unit, wherein the moving unit may be configured to fold the flexible material inward or outward in the unfolded state when rotating relative to the sliding unit along the motion guide unit.

[0017] The motion guiding unit may be recessed to form a circular guide groove to correspond to the rotation path of the moving unit. The moving unit may include: a rotating shaft rotatably disposed at a position rotatable relative to the motion guiding unit; a moving block fixed on the rotating shaft; a sliding block connected to the moving block and slidable in the longitudinal direction; and a guide block rotatably connected to the sliding block and protruding to form a guide protrusion that is embedded in and connected to the guide groove, so that the guide block can move along the guide groove to correspond to the rotation of the moving unit, and the moving unit may be fixed on the guide block.

[0018] The guide slot may include: an inward fold stop configured to mark the position where the inward fold is complete; and an outward fold stop configured to mark the position where the outward fold is complete.

[0019] The guide groove may include: a first arc-shaped inward fold groove that creates a movement path for the guide protrusion in response to an inward folding operation on the movement path of the moving unit; a second arc-shaped inward fold groove that is parallel to the outer side of the first inward fold groove and configured to create a movement path for the guide protrusion in response to an inward folding operation on the movement path of the moving unit; a first arc-shaped outward fold groove that communicates with the first arc-shaped inward fold groove and is configured to create a movement path for the guide protrusion in response to an outward folding operation on the movement path of the moving unit; and a second arc-shaped outward fold groove that is parallel to the outer side of the first arc-shaped outward fold groove and communicates with the second arc-shaped inward fold groove, and is configured to create a movement path for the guide protrusion in response to an outward folding operation on the movement path of the moving unit.

[0020] The guide protrusion may include: a first protrusion configured to move within a first arcuate inner groove and a first arcuate outer groove; and a second protrusion configured to move within a second arcuate inner groove and a second arcuate outer groove. Either the first protrusion or the second protrusion may be included in either imaginary straight line passing through the location, and the other protrusion may be included in another imaginary straight line passing through the location.

[0021] The folding unit may further include at least one of the following: a motion drive unit configured to rotate the motion unit relative to the motion guide unit; and a rotation limiting unit configured to select whether the moving unit rotates relative to the motion guide unit at the position.

[0022] The sliding unit may further include a motion limit sensor unit configured to detect the state of the clamping member approaching the folding unit and the state of the clamping member moving away from the folding unit, so as to limit the sliding movement of the slider.

[0023] The sliding device may further include a sliding support unit, which is configured to support the flexible material when the sliding unit is slidably moved from the base unit while the flexible material is folded inward or outward.

[0024] When the radius of the inward bending portion F1 formed in the flexible material F in the inward folding state is R0, and the radius of the outward bending portion F2 formed in the flexible material F in the outward folding state is R1, R1 can represent a radius greater than R0, and based on the inward folding operation, the interval distance between the sliding unit and the moving unit can be represented as πR1.

[0025] According to the present invention, the flexible material durability testing system may include: a sliding device according to any one of claims 1 to 9; a working plate unit connected to a base unit; and a support plate unit disposed in the working plate unit and configured to support a sliding motor disposed in the sliding unit and a motion drive unit disposed in the folding unit.

[0026] The work plate units can be connected to form a connected space to correspond to the folded space.

[0027] Invention Effects

[0028] According to the sliding device and testing system for testing the durability of flexible materials of the present invention, when a folding test is performed on a flexible material, the inward folding operation and the outward folding operation of the flexible material can be performed by a folding unit in the unfolded state, and a sliding operation can be performed to change the position of the bent portion formed in the flexible material in the folded state.

[0029] In other words, when conducting folding tests on thin-film flexible materials, taking the flexible material as a reference, since a folding unit repeatedly folds each side of the flexible material by 180 degrees, the flexible material can be repeatedly folded in the opposite direction, and as the sliding unit slides in the folded state, the position of the curved portion formed in the flexible material can change.

[0030] Furthermore, by connecting the sliding unit and the folding unit in the base unit, the initial setup of the flexible material can be clarified, as can the sliding operation of the sliding unit and the folding operation of the folding unit, and the sliding of the sliding unit in the folded state can be clarified.

[0031] In addition, through the detailed structure of the sliding unit, the sliding of the slider on the base unit can be smooth, thereby preventing the folding unit from interfering with the sliding unit in response to the outward folding operation of the folding unit.

[0032] Furthermore, through the additional structure of the sliding motor and the sliding change part in the sliding unit, the linear motion of the sliding member can be stabilized by the rotational force of the sliding motor, and the linear reciprocating motion of the flexible material can be clearly defined.

[0033] In addition, since the sliding unit includes a connecting bracket, the connecting bracket and the sliding change part are detachably connected to each other, and the connecting bracket and the sliding part can be separated from the sliding change part, the replacement and maintenance of the sliding device can be simplified according to the specifications of the flexible material.

[0034] Furthermore, through the detailed structure of the sliding change part in the sliding unit, the rotational motion of the sliding motor is converted into the linear reciprocating motion of the sliding member, thereby effectively executing the sliding motion of the sliding member.

[0035] Furthermore, the detailed structure of the folding unit clarifies the folding operation of the flexible material, and the folding can be performed differently depending on the radius of the inward bending portion and the radius of the outward bending portion.

[0036] Furthermore, the connection between the motion guide unit and the motion unit in the folding unit prevents the motion unit from unnecessarily flowing during its rotation.

[0037] Furthermore, thanks to the detailed structure of the moving unit, the rotation of the moving unit is performed smoothly, and when folding tests are conducted on flexible materials, as well as when performing inward and outward folding operations, the flexible materials are prevented from being subjected to miscellaneous forces, including tension. Therefore, the reliability of the test is high and the durability test can be performed accurately.

[0038] Furthermore, through the structure of the stopper, when folding tests are performed on flexible materials, and when inward and outward folding operations are carried out, the guide protrusion stops in the guide groove, and the folding completion state of the flexible material can be clearly defined.

[0039] In addition, the detailed structure of the guide groove can clarify the rotation path of the moving unit and stabilize the parallel state of the clamping member of the sliding unit and the moving unit at the folded position.

[0040] Furthermore, the detailed structure of the guiding protrusions stabilizes the operation of the moving unit when it rotates.

[0041] In addition, the folding test can be automated through the structure of the motion drive unit.

[0042] Furthermore, by utilizing the structure of the rotation limiting unit, the present invention allows for the selection of whether the moving unit rotates.

[0043] In addition, the sliding of the slider is restricted by the additional structure of the motion limit sensor in the sliding unit, so that the initial position of the slider in the unfolded state can be clearly defined in response to the inward folding operation and the outward folding operation.

[0044] Furthermore, through the additional structure of the sliding support unit, when the slider can slide slidably in the folded state of the flexible material, the radius of the bent portion formed in the flexible material is maintained, and the position tracking of the bent portion can be checked.

[0045] In addition, by limiting the number of units, inward folding and outward folding operations can be prevented from interfering with each other in a folding unit, and flexible materials can be safely protected.

[0046] Furthermore, according to the present invention, the base unit of the sliding device can be restored to its original position by means of the additional structure of the working plate unit, and the base unit can be prevented from moving to correspond to the operation of the sliding device.

[0047] Furthermore, through the additional structure of the support plate unit, the sliding motor of the sliding device, the motion drive unit of the folding unit, the sliding change part and the motion limit sensor part are locked in their original positions, and the power transmission system can be clearly defined.

[0048] In addition, the connecting space, corresponding to the outward folding operation, prevents the moving unit from interfering with the work plate unit. Attached Figure Description

Detailed Implementation

[0061] In the following description, a sliding device and testing system for testing the durability of flexible materials according to embodiments of the present invention will be described with reference to the accompanying drawings. The invention is not limited to the embodiments described herein. Furthermore, in the following description of the invention, detailed descriptions of known functions and components included herein will be omitted in order to elucidate the subject matter of the invention.

[0062] The test system for testing the durability of flexible materials according to an embodiment of the present invention may include a sliding device 100 and a system body 200.

[0063] The sliding device 100 can not only perform folding operations on the flexible material F in its unfolded state, but also slide operations relative to one side of the flexible material F in its folded state. The sliding device 100 can be a sliding device 100 for durability testing of flexible materials according to an embodiment of the present invention.

[0064] In embodiments of the present invention, the flexible material F includes various sheets, various films, flexible displays, etc., and forms a curved portion upon completion of the folding operation. In embodiments of the present invention, when the flexible material F is folded, the flexible material F loses its function.

[0065] According to an embodiment of the present invention, the sliding device 100 for durability testing of flexible material F includes a base unit B, a sliding unit 10 and a folding unit, and may include a sliding support unit 70.

[0066] The base unit B can form the bottom of the sliding device 100. Preferably, the base unit B has a through-hole forming a folding space B1 to correspond to the folding operation of the folding unit. Furthermore, corresponding to the width of the folding space B1, it is advantageous that folding brackets B2 are respectively provided at both ends of the base unit B in the lateral direction. In addition, corresponding to the width of the folding space B1, it is advantageous that slide rails 11 are respectively provided at both ends of the base unit B in the lateral direction, spaced apart from the folding brackets B2. The lateral direction of the base unit B is substantially perpendicular to the longitudinal direction of the base unit B or the sliding direction of the sliding unit 10, and substantially parallel to the axial direction of the rotation axis 41.

[0067] The base unit B is connected to the work plate unit 300 of the system body 200. The base unit B can be mounted and removed from the work plate unit 300 via a device fixing unit (not shown) that serves as a medium, and part or all of the sliding device 100 can be easily maintained.

[0068] The sliding unit 10 fixes one side of the flexible material F to be tested. The sliding unit 10 is connected to the base unit B and can be slidably moved. The sliding unit 10 can be slidably moved on the base unit B when the flexible material F is folded inward or outward, thereby changing the position of the bent portions F1 and F2 formed in the flexible material F.

[0069] The sliding unit 10 may include a slide rail 11, a slider 12, and a clamping member 16.

[0070] The slide rail 11 is formed to be relatively long along the longitudinal direction of the base unit B. The slide rails 11 are arranged in pairs and are respectively located at both ends of the base unit B in the lateral direction, thereby ensuring sufficient folding space B1.

[0071] The slider 12 is connected to the slide rail 11 for slidable movement. The slider 12 is configured as a pair corresponding to a pair of slide rails 11. Alternatively, at least one slider 12 may be configured to correspond to one slide rail 11. The sliding bracket 121 is connected to the slider 12 in a stackable manner. The two ends of the clamping member 16 are respectively connected to a pair of sliding brackets 121 in the lateral direction of the base unit B.

[0072] In this paper, the connection structure between the slide rail 11 and the slider 12 is not limited, and various conventional forms are used to make the slider 12 slide slidably on the slide rail 11 and to prevent the slider 12 from moving.

[0073] The clamping member 16 is connected to two sliders 12. Both ends of the clamping member 16 are connected to sliding supports 121 of the pair of sliders 12. The clamping member 16 secures one side of the flexible material F in a stackable manner.

[0074] The sliding unit 10 includes a sliding motor 14 and a sliding change part 15.

[0075] The sliding motor 14 generates a rotational force to cause the slider 12 to slide. It is advantageous for the sliding motor 14 to be connected to the support plate unit 400. The sliding motor 14 is connected to the sliding adjustment unit 15. The sliding motor 14 includes a sliding shaft 141 connected to the sliding adjustment unit 15.

[0076] The slider 12 is slidably moved via the sliding change part 15 by the rotational force of the sliding motor 14. The sliding change part 15 may include a drive roller 151, an idler roller 152, a transmission belt 153, a sliding guide 154, and a change movable member 155.

[0077] The drive roller 151 is connected to the sliding shaft 141 of the sliding motor 14 and is rotated by the sliding motor 14. The drive roller 151 is rotatably connected to the support plate unit 400.

[0078] The idler roller 152 is arranged spaced apart from the drive roller 151 in the longitudinal direction of the base unit B and is rotatable. The idler roller 152 is rotatably connected to the support plate unit 400. The idler roller 152 is connected to the support plate unit 400 to slide along the longitudinal direction of the base unit B, thereby adjusting the tension of the drive belt 153.

[0079] The drive belt 153 connects the drive roller 151 and the idler roller 152 in a track manner.

[0080] The drive roller 151 and idler roller 152 are composed of synchronous pulleys, while the transmission belt 153 is composed of a synchronous belt, so that the rotational force of the sliding motor 14 can be stably transmitted, and the transmission belt 153 can move stably in a track manner without slipping.

[0081] The sliding guide 154 is spaced apart from the drive belt 153 and is formed to a considerable length along the longitudinal direction of the base unit B. The sliding guide 154 forms a path that alters the movement of the movable member 155. The sliding guide 154 can be connected to the support plate unit 400 or the work plate unit 300.

[0082] The movable component 155 is slidably connected to the sliding guide 154 and fixed to the drive belt 153. The movable component 155 is connected to the slider 12 or the sliding bracket 121 and is slidably movable along the sliding guide 154, while the slider 12 is slidably movable along the slide rail 11. The movable component 155 includes: a bracket 156 for connecting the movable component 155 to the drive belt 153; and a loading / unloading protrusion 157 for detachably connecting the movable component 155 to the slider 12.

[0083] The sliding unit 10 may include a connecting bracket 13.

[0084] A connecting bracket 13 is disposed on the slider 12 or the sliding bracket 121 facing the sliding change portion 15. The connecting bracket 13 is detachably connected to the loading / unloading protrusion 157 of the sliding change portion 15. Since the connecting bracket 13 is recessed to form a loading / unloading groove 131 into which the loading / unloading protrusion 157 is inserted, the connecting bracket 13 and the change movement member 155 of the sliding change portion 15 can be detachably connected to each other in response to the insertion connection between the loading / unloading groove 131 and the loading / unloading protrusion 157.

[0085] The sliding unit 10 may include a motion limit sensor unit 17.

[0086] The motion limit sensor unit 17 can detect the state of the clamping member 16 approaching the folding unit and the state of the clamping member 16 moving away from the folding unit. The motion limit sensor unit 17 can limit the sliding amount of the slider 12. The motion limit sensor unit 17 may include a first limit part 171, a second limit part 172, and a communicating protrusion 173.

[0087] A connecting protrusion 173 is provided in the sliding change part 15 or the slider 12. The connecting protrusion 173 can indicate the position of the clamping member 16 facing the end of the folding unit. The connecting protrusion 173 can be provided in the changing movable member 155 of the sliding change part 15, the drive belt 153, the slider 12, or the sliding bracket 121.

[0088] The first limiting part 171 is arranged at a distance from the sliding changing part 15 to correspond to the state where the clamping member 16 is away from the folding unit. The first limiting part 171 is connected to the support plate unit 400. The first limiting part 171 detects the communicating protrusion 173. When the first limiting part 171 detects the communicating protrusion 173, it stops the sliding of the clamping member 16 away from the folding unit and implements the sliding of the slider 12 towards the folding unit.

[0089] The second limiting part 172 is arranged spaced apart from the sliding changing part 15 to correspond to the state where the clamping member 16 approaches the folding unit. The second limiting part 172 is connected to the support plate unit 400. The second limiting part 172 detects the communicating protrusion 173. When the second limiting part 172 detects the communicating protrusion 173, it stops the sliding of the clamping member 16 toward the folding unit and implements the sliding of the slider 12 away from the folding unit.

[0090] The folding unit is fixed to the other side of the flexible material F to be tested. The folding unit is arranged to be spaced apart from the sliding unit 10. The folding unit rotates with respect to the sliding unit 10 to fold the flexible material F inward or outward in its unfolded state.

[0091] The folding unit may include a moving unit 20, a motion guiding unit 30, and a motion unit 40.

[0092] The moving unit 20 is arranged spaced apart from the sliding unit 10 to form the same plane as the clamping member 16 of the sliding unit 10 in the unfolded state. The moving unit 20 fixes the other side of the flexible material F. When the moving unit 20 rotates along the motion guide unit 30 with the sliding unit 10 as a reference, the flexible material F in the unfolded state can be folded inward or outward.

[0093] The two ends of the moving unit 20 are fixed to the moving unit 40 by the moving bracket 21 as a medium, corresponding to the lateral direction of the base unit B.

[0094] The moving unit 20 can pivot on the moving unit 40 in response to the inward folding operation and the outward folding operation of the flexible material F, and can slide slidably along the normal direction passing through the intermediate position between the sliding unit 10 and the moving unit 20. Therefore, when the moving unit 20 folds the flexible material F inward or outward in its unfolded state, no extraneous forces, including tension, are applied to the flexible material F.

[0095] like Figure 7 As shown, the radius of the inwardly folded portion F1 formed in the flexible material F in the inwardly folded state is R0, while the radius of the outwardly folded portion F2 formed in the flexible material F in the outwardly folded state is R1. R1 is a radius greater than R0, and the distance between the sliding unit 10 and the moving unit 20, based on the inwardly folding operation, can be denoted as πR1. In this embodiment of the invention, R1 can represent two to three times the value of R0.

[0096] Therefore, in this embodiment of the invention, when a folding unit folds the flexible material F inward or outward in an unfolded state, the inward folding operation and the outward folding operation do not interfere with each other, and the flexible material F can be bent smoothly.

[0097] The motion guide unit 30 forms a rotation path for the moving unit 20, causing the moving unit 20 to rotate at a position between the sliding unit 10 and the moving unit 20. A pair of motion guide units 30 are arranged spaced apart from each other so as to face each other with respect to the folding space B1, and the pair of motion guide units 30 are respectively connected to a pair of folding supports B2.

[0098] The motion guiding unit 30 has a recessed circular guide groove corresponding to the rotation path of the moving unit 20. The center of the circular guide groove can be selected as the position between the sliding unit 10 and the moving unit 20.

[0099] The guide groove can be formed as a double groove.

[0100] The guide groove may include: a first arc-shaped inward folding groove 31, forming a movement path for a guide protrusion (first protrusion 443) disposed in the motion unit 40, in response to an inward folding operation on the movement path of the motion unit 20; a second arc-shaped inward folding groove 32, disposed parallel to the outer side of the first arc-shaped inward folding groove 31, and forming a movement path for a guide protrusion (second protrusion 444) disposed in the motion unit 40, in response to an inward folding operation on the movement path of the motion unit 20; a first arc-shaped outward folding groove 33, which communicates with the first arc-shaped inward folding groove 31, and forms a movement path for a guide protrusion (first protrusion 443) disposed in the motion unit 40, in response to an outward folding operation on the movement path of the motion unit 20; and a second arc-shaped outward folding groove 34, which communicates with the second arc-shaped inward folding groove 32, and is disposed parallel to the outer side of the first outward folding groove 33, and forms a movement path for a guide protrusion (second protrusion 444) disposed in the motion unit 40, in response to an outward folding operation on the movement path of the motion unit 20.

[0101] Then, the first arc-shaped inner groove 31 and the first arc-shaped outer groove 33 can represent a circular shape centered at the said position, while the second arc-shaped inner groove 32 and the second arc-shaped outer groove 34 can represent a circular shape centered at the said position.

[0102] Here, the guide groove includes an inward fold stop 301 that indicates the inward folding completion position and an outward fold stop 302 that indicates the outward folding completion position, thereby preventing the moving unit 20 from rotating further in the inward folding completion state and the outward folding completion state of the flexible material F.

[0103] In other words, the inner fold stop 301 is formed at the free end of the first arc-shaped inner fold groove 31 and the free end of the second arc-shaped inner fold groove 32, and the outer fold stop 302 is formed at the free end of the first arc-shaped outer fold groove 33 and the free end of the second arc-shaped outer fold groove 34.

[0104] Here, on the side, at the position of the inward folding stop 301 based on the sliding unit 10, since the inward folding stop 301 formed on the free end of the second arc-shaped inward folding groove 32 is arranged lower than the inward folding stop 301 formed on the free end of the first arc-shaped inward folding groove 31, when the inward folding of the flexible material F is completed, the clamping member 16 of the sliding unit 10 and the moving unit 20 can be arranged to be approximately parallel to each other.

[0105] Furthermore, on the side, at the position of the outward folding stop 302 based on the sliding unit 10, since the outward folding stop 302 formed on the free end of the second arc-shaped outward folding groove 34 is arranged lower than the outward folding stop 302 formed on the free end of the first arc-shaped outward folding groove 33, when the outward folding of the flexible material F is completed, the clamping member 16 of the sliding unit 10 and the moving unit 20 can be arranged to be approximately parallel to each other.

[0106] The motion unit 40 connects the motion guide unit 30 to the moving unit 20. The motion unit 40 may include a rotation axis 41, a motion block 42, a slider 43, and a guide block 44. Here, the moving unit 20 is fixed to the guide block 44 via a moving bracket 21.

[0107] The rotating shaft 41 is positioned so that it can be rotated to the motion guide unit 30. The rotating shaft 41 is rotatably mounted on the folding bracket B2. The rotating shaft 41 is rotatably connected to the motion guide unit 30 and the folding bracket B2 via a bearing that serves as a medium.

[0108] The moving block 42 is fixed to the rotating shaft 41. The moving block 42 protrudes in an imaginary straight direction passing through the said position. The moving block 42 may be recessed to form a guide seat portion 421 for connection to the connecting guide 45. The moving block 42 may be recessed to form a loading and unloading block seat portion 422, in which the fixing body 442 of the guide block 44 is detachably inserted in response to the sliding of the sliding block 43.

[0109] The sliding block 43 is connected to the moving block 42 and can slide in the longitudinal direction. The sliding block 43 has a through pivot hole 431, into which the guide block 44 can be rotatably inserted, thereby effectively connecting the guide block 44 and the moving unit 20 to each other. The block support sleeve 432 can be disposed on the inner wall of the pivot hole 431 to rotatably support the rotating body 441 of the guide block 44.

[0110] The guide block 44 is rotatably connected to the sliding block 43. The guide block 44 has a protruding guide protrusion that engages with a guide groove, thereby moving along the guide groove in response to rotation of the moving unit 20. The guide block 44 is rotatably connected to the sliding block 43 and may include: a rotating body 441 to which the moving unit 20 is fixed via a moving bracket 21; and a fixing body 442 disposed on the rotating body 441 and having the guide protrusion thereon.

[0111] Then, as the moving unit 20 rotates, the sliding block 43 slides with reference to the moving block 42, and as the guide block 44 rotates with reference to the sliding block 43, the guide protrusion moves stably while being inserted into the guide groove. In the inward folding state and the outward folding state of the flexible material F, the clamping member 16 of the sliding unit 10 and the moving unit 20 can be arranged to be approximately parallel to each other.

[0112] Here, corresponding to the guide groove of the double-groove structure, the guide protrusion is two spaced apart from each other and protruding on the fixed body 442.

[0113] The guide protrusion includes: a first protrusion 443, movable within a first arcuate inner fold groove 31 and a first arcuate outer fold groove 33; and a second protrusion 444, spaced apart from the first protrusion 443 and movable within a second arcuate inner fold groove 32 and a second arcuate outer fold groove 34. Here, either the first protrusion 443 or the second protrusion 444 is included in either imaginary straight line passing through the said position, and the other of the first protrusion 443 and the second protrusion 444 is included in another imaginary straight line passing through the said position. In an embodiment of the invention, when the first protrusion 443 is included in either imaginary straight line passing through the said position, the second protrusion 444 is arranged in front of the imaginary straight line including the first protrusion 443 along an inward folding direction.

[0114] The motion unit 40 may include at least one of the connecting guide 45 and the support bearing 46.

[0115] A connecting guide 45 connects the moving block 42 to the sliding block 43. The connecting guide 45 may include a moving support portion connected to a guide seat portion 421 of the moving block 42, and a guide support portion connected to the sliding block 43 to face the moving support portion. The connecting guide 45 may also include a reducer slidably and movablely embedded between the moving support portion and the guide support portion. The connecting guide 45 then allows for smooth sliding of the sliding block 43 relative to the moving block 42. Furthermore, the reducer may be arranged between the moving support portion and the guide support portion to reduce friction.

[0116] The support bearing 46 can be inserted into the pivot hole 431 of the sliding block 43. The support bearing 46 can be respectively disposed on both sides of the block support sleeve 432. The support bearing 46 can rotatably support the rotating body 441 of the guide block 44 in the sliding block 43.

[0117] The folding unit may include a motion drive unit 50 and a rotation limit unit (not shown).

[0118] The motion drive unit 50 rotates the motion unit 40 relative to the motion guide unit 30. The motion drive unit 50 rotates the rotation axis 41 of the motion unit 40 back and forth by applying power. The motion drive unit 50 includes a motion drive shaft 51, which is connected to the rotation axis 41 of the motion unit 40.

[0119] The motion drive unit 50 may include a reciprocating loading and unloading section 52, which detachably connects the motion drive shaft 51 to the rotating shaft 41.

[0120] The reciprocating loading / unloading section 52 may include a first connector section 521 connected to the rotating shaft 41, and a second connector section 523 connected to the motion drive shaft 51 of the motion drive unit 50. At least two first loading / unloading sections 522 are formed by protruding from the first connector section 521 toward the second connector section 523 and spaced apart from each other. At least two second loading / unloading sections 524 are formed by protruding from the second connector section 523 toward the first connector section 521 and spaced apart from each other. Since the first connector section 521 and the second connector section 523 are connected to each other, and the first loading / unloading sections 522 and 524 are arranged alternately, the rotational force of the motion drive shaft 51 can be transmitted to the rotating shaft 41. Then, when the base unit B moves to correspond to the axial direction of the rotating shaft 41 or the motion drive shaft 51, the first connector section 521 and the second connector section 523 can separate from each other.

[0121] The reciprocating loading / unloading section 52 may further include a connecting portion 525 located between the first connector portion 521 and the second connector portion 523, with the first connector portion 521 and the second connector portion 523 respectively embedded and connected. The connecting portion 525 includes: a first connecting loading / unloading portion 526 recessed on the surface opposite to the first connector portion 521, corresponding to the first loading / unloading portion 522; and a second connecting loading / unloading portion 527 recessed on the surface opposite to the second connector portion 523, corresponding to the second loading / unloading portion 524. The first loading / unloading portion 522 is then embedded and connected to the first connecting loading / unloading portion 526, and the second loading / unloading portion 524 is embedded and connected to the second connecting loading / unloading portion 527, such that the rotational force of the motion drive shaft 51 can be transmitted to the rotating shaft 41. Then, when the base unit B moves to correspond to the axial direction of the rotating shaft 41 or the motion drive shaft 51, the first connector portion 521, the connecting portion 525, and the second connector portion 523 can be separated from each other. Here, when the reciprocating loading and unloading part 52 includes a first connector part 521, a joint part 525, and a second connector part 523, if a first joint loading and unloading part 526 is recessed in the first connector part 521, then a first loading and unloading part 522 will be protruded in the joint part 525; if a second joint loading and unloading part 527 is recessed in the second connector part 523, then a second loading and unloading part 524 will be protruded in the joint part 525.

[0122] A rotation limiting unit (not shown) selects whether the moving unit 20 or the motion unit 40 rotates relative to the motion guide unit 30 at the stated position. The rotation limiting unit (not shown) may include a limiting bracket disposed in either of a pair of folding brackets B2, and a limiting rod pivotally connected to the limiting bracket. The limiting rod has a through-hole through which the rotation shaft 41 passes.

[0123] Then, in the initial state, with the limiting horizontal position approximately parallel to the folding bracket B2, the rotating shaft 41 is rotatably arranged in the shaft through hole, so that the limiting rod does not interfere with the rotating shaft 41. When the limiting rod is pivoted to a position inclined relative to the folding bracket B2, the inner surface of the shaft through hole contacts or is in close contact with the support surface formed on the outer peripheral surface of the rotating shaft 41. Therefore, the limiting rod is locked to the rotating shaft 41 to prevent the rotating shaft 41 from rotating.

[0124] When the sliding unit 10 slides on the base unit B, the sliding support unit 70 supports the flexible material F, wherein the flexible material F is in an inward or outward folded state.

[0125] The sliding support unit 70 may include at least one of a first support member 71, a second support member 72, and a third support member 73.

[0126] The first support member 71 is formed by extending from the clamping member 16, with the capability to fold inward. Figure 10 As shown, when the inward folding operation is completed, the first support member 71 is formed by extending on the same plane as the clamping member 16 of the sliding unit 10. When the inward folding operation is completed and the clamping member 16 slides, the first support member 71 can move together with the clamping member 16 and support the flexible material F. Therefore, the bent portion (inward folded bent portion F1) of the flexible material F moves to maintain its radius and prevents the flexible material F from sagging. Since the first support member 71 is connected to the clamping member 16 when the inward folding operation is completed, the first support member 71 can be prevented from interfering with the moving unit 20 during the inward folding operation. Here, the connection between the clamping member 16 and the first support member 71 is unrestricted.

[0127] The second support member 72 is supported and stacked on a flexible material F that is stacked on the moving unit 20. For example... Figure 12As shown, when the outward folding operation is completed, the second support member 72 is stacked on and supported by the flexible material F stacked at one end of the moving unit 20. When the clamping member 16 slides in the completed outward folding state, the second support member 72 supports the flexible material F, and the bent portion (outward folded bent portion F2) of the flexible material F moves. Therefore, the flexible material F can be supported horizontally, and sagging of the flexible material F can be prevented. In the completed outward folding state, the second support member 72 can be stacked on and supported by the flexible material F in the moving unit 20, or it can be stacked on and supported by the flexible material F in the moving unit 20 in the unfolded state. The second support member 72 can be connected to the support member connecting portion provided in the moving bracket 21.

[0128] The third support member 73 is stacked on and supported by the flexible material F based on an outward folding operation, and the flexible material F is stacked on the clamping member 16. For example... Figure 12 As shown, when the clamping member 16 slides in the outward-folded state, the third support member 73 supports the flexible material F, and the bent portion (outward-folded bent portion F2) of the flexible material F moves. Therefore, the third support member 73, together with the second support member 72, supports the flexible material F to maintain a constant radius and prevents shape changes in the bent portion (outward-folded bent portion F2) of the flexible material F. The third support member 73 can be stacked on and supported by the flexible material F in the clamping member 16 in the unfolded state, or it can be stacked on and supported by the flexible material F in the clamping member 16 in the outward-folded state. Here, the third support member 73 can be connected to the clamping member 16 and simultaneously stacked on and supported by the flexible material F on the clamping member 16.

[0129] Then, since the inward folding operation is performed in the unfolded state (when the second limiting part 172 detects the connecting protrusion 173), the clamping member 16 approaches the moving unit 20 to correspond to the inward folding operation, with the interval distance denoted as πR1, therefore, in such a state... Figure 9 and Figure 10 In the inward folded-in state shown, the clamping member 16 slides more smoothly, and the first support member 71 can stably support the flexible material F.

[0130] Furthermore, since the outward folding operation is performed in the unfolded state (when the first limiting part 171 detects the communicating protrusion 173), the clamping member 16 moves away from the moving unit 20 to correspond to the outward folding operation, thus in such a state... Figure 11 and Figure 12 In the outward folded-out state shown, the clamping member 16 slides more smoothly, and the second support member 72 and the third support member 73 can stably support the flexible material F while cooperating with each other.

[0131] The sliding device 100 is connected to the system body 200. In the system body 200, the test space is opened and closed through the test door, so that various components such as the sliding motor 14 and the motion drive unit 50 arranged in the test space can be maintained when the test space is open, and various components such as the sliding motor 14 and the motion drive unit 50 arranged in the test space can be protected when the test space is closed.

[0132] The system main body 200 has an operating space 201 in which the sliding device 100 is arranged, and the operating space 201 can be opened and closed by an operating door 210. A camera unit 220 can be installed in the upper part of the operating space 201 of the system main body 200 to monitor the sliding device 100. The camera unit 220 can be installed in the support plate unit 400 or the operating door 210 to capture the sliding device 100.

[0133] The system body 200 includes a work plate unit 300 and a support plate unit 400, and may include at least one of a control unit (not shown) and a display (not shown).

[0134] The base unit B is connected to the work plate unit 300. The work plate unit 300 has a through-space 310 corresponding to the folding space B1. Therefore, when the moving unit 20 of the folding unit performs the folding operation, it can prevent the moving unit 20 from interfering with the work plate unit 300.

[0135] The support plate unit 400 is plate-shaped and is disposed on the work plate unit 300. The support plate unit 400 can protrude substantially vertically onto the upper surface of the work plate unit 300. The support plate unit 400 supports the motion drive unit 50 and the sliding motor 14 disposed in the folding unit and sliding unit 10 toward the detection space. The support plate unit 400 supports the sliding change part 15 disposed in the sliding unit 10 toward the base unit B.

[0136] The control unit (not shown) controls the operation of the sliding device 100. The control unit (not shown) specifies the unfolded state in response to the detection operation of the motion limit sensor 17, and controls the operation of the motion drive unit 50 to control the inward folding operation and the outward folding operation. The control unit (not shown) controls the operation of the sliding motor 14, which operates together with the motion limit sensor 17, thereby controlling the sliding of the clamping member 16.

[0137] The control unit (not shown) controls the operation of the camera unit 220.

[0138] The display (not shown) visually shows the operation of the sliding device 100 and the control status of the control unit (not shown).

[0139] In the following description, according to embodiments of the present invention, the operation of the sliding device 100 and the test system for testing the durability of the flexible material F will be described.

[0140] <Inward folding operation>

[0141] According to the specifications of the flexible material F, the sliding device 100 is fixed in its original position on the working plate unit 300. Here, the clamping member 16 of the sliding unit 10 and the moving unit 20 are spaced apart by a distance of πR1, thereby forming a plane that is approximately the same as the moving unit 20, and the second limiting part 172 is in the state of detecting the connecting protrusion 173.

[0142] Then, when the two ends of the flexible material F are fixed to the clamping member 16 and the moving unit 20 respectively and the motion drive unit 50 is running, the first protrusion 443 and the second protrusion 444 move along the first arc-shaped inner fold groove 31 and the second arc-shaped inner fold groove 32 respectively, and then stop while being supported by the inner fold stop member 301, thereby completing the inward folding operation.

[0143] Next, the sliding unit 10 can slide the clamping member 16 away from the rotation axis 41 so that the first limiting part 171 detects the communicating protrusion 173. Furthermore, when the first limiting part 171 detects the communicating protrusion 173, in order to make the second limiting part 172 detect the communicating protrusion 173, the sliding unit can slidably move the clamping member 16 so that the clamping member 16 approaches the rotation axis 41.

[0144] <Expand Operation>

[0145] According to the specifications of the flexible material F, the sliding device 100 is fixed in its original position on the working plate unit 300. Here, the clamping member 16 of the sliding unit 10 forms a plane that is approximately the same as the moving unit 20, and the first limiting part 171 is in the state of detecting the connecting protrusion 173.

[0146] Furthermore, when the two ends of the flexible material F are fixed to the clamping member 16 and the moving unit 20 respectively, and the motion drive unit 50 is running, the first protrusion 443 and the second protrusion 444 move along the first arc-shaped outer folding groove 33 and the second arc-shaped outer folding groove 34 respectively, and then stop while being supported by the outer folding stop member 302, thereby completing the outward folding operation.

[0147] Next, in order to make the second limiting part 172 detect the communicating protrusion 173, the sliding unit 10 slidably moves the clamping member 16 so that the clamping member 16 approaches the rotation axis 41. Furthermore, in order to make the second limiting part 172 also detect the communicating protrusion 173 when the first limiting part 171 detects the communicating protrusion 173, the sliding unit 10 slidably moves the clamping member 16 so that the clamping member 16 moves away from the rotation axis 41.

[0148] According to the sliding device 100 and test system for the durability test of flexible material F described above, when the folding test of flexible material F is carried out, the inward folding operation and the outward folding operation of flexible material F are performed by a folding unit in the unfolded state, and the folding unit can perform a sliding operation, thereby changing the formation position of the bent portions F1 and F2 formed in the flexible material F in the folded state.

[0149] In other words, when a folding test is performed on a thin-film flexible material F, the flexible material F is used as a reference. Since a folding unit repeatedly folds each side of the flexible material F by 180 degrees, the flexible material F can be repeatedly folded in the opposite direction. As the sliding unit 10 slides in the folded state, the positions of the bent portions F1 and F2 formed in the flexible material F can change.

[0150] Furthermore, by connecting the sliding unit 10 and the folding unit in the base unit B, the initial setting of the flexible material F can be clarified, as can the sliding operation of the sliding unit 10 and the folding operation of the folding unit, and the sliding of the sliding unit 10 in the folded state can be clarified.

[0151] Furthermore, through the detailed structure of the sliding unit 10, the sliding of the slider 12 on the base unit B can be smooth, which can prevent the folding unit from interfering with the sliding unit 10 in response to the outward folding operation of the folding unit.

[0152] Furthermore, through the additional structure of the sliding motor 14 and the sliding change part 15 in the sliding unit 10, the linear motion of the sliding member 12 can be stabilized by the rotational force of the sliding motor 14, and the linear reciprocating motion of the flexible material F can be clearly defined.

[0153] In addition, through the additional structure of the connecting bracket 13 in the sliding unit 10, the connecting bracket 13 and the sliding change part 15 can be detachably connected to each other, and the connecting bracket 13 and the sliding member 12 can be separated from the sliding change part 15, so that the sliding device 100 can be easily maintained and replaced according to the specifications of the flexible material F.

[0154] Furthermore, through the detailed structure of the sliding change unit 15 in the sliding unit 10, the rotational motion of the sliding motor 14 is converted into the linear reciprocating motion of the sliding member 12, thereby effectively executing the sliding motion of the sliding member 12.

[0155] Furthermore, the folding operation of the flexible material F can be clarified through the detailed structure of the folding unit, and can be implemented differently from each other based on the radius R0 of the inward folding bending portion F1 and the radius R1 of the outward folding bending portion F2.

[0156] Furthermore, the connection between the motion guide unit 30 and the motion unit 40 in the folding unit prevents the motion unit 20 from unnecessarily flowing during the rotation of the motion unit 20.

[0157] Furthermore, thanks to the detailed structure of the motion unit 40, the rotation of the moving unit 20 is performed smoothly, and when the flexible material F is folded for testing, as well as when performing inward folding and outward folding operations, the flexible material F is protected from being subjected to unwanted forces, including tension. Therefore, the reliability of the test is high and the durability test can be performed accurately.

[0158] Furthermore, through the structure of the stoppers 301 and 302, when the flexible material F is folded for testing, and when inward and outward folding operations are performed, the guide protrusion stops in the guide groove, and the folding completion state of the flexible material F can be clearly defined.

[0159] Furthermore, the detailed structure of the guide groove can clarify the rotation path of the moving unit 20 and stabilize the parallel state between the clamping member 16 of the sliding unit 10 and the moving unit 20 at the folded position.

[0160] Furthermore, the detailed structure of the guiding protrusions stabilizes the operation of the motion unit 40 when the moving unit 20 rotates.

[0161] In addition, the folding test can be automated through the structure of the motion drive unit 50.

[0162] Furthermore, the structure of the rotation limiting unit (not shown) allows selection of whether the moving unit 20 rotates.

[0163] In addition, the sliding of the slider 12 is restricted by the additional structure of the motion limit sensor unit 17 in the sliding unit 10, and the initial position of the slider 12 in the unfolded state can be clearly defined in response to the inward folding operation and the outward folding operation.

[0164] Furthermore, through the additional structure of the sliding support unit 70, when the slider 12 moves slidably in the folded state of the flexible material F, the radius of the bent portion formed in the flexible material F is maintained, and the position tracking of the bent portion can be checked.

[0165] In addition, by limiting the number of units, inward folding and outward folding operations can be prevented from interfering with each other in a folding unit, and the flexible material F can be safely protected.

[0166] Furthermore, through the additional structure of the working plate unit 300, the base unit B of the sliding device 100 can be located in its original position and correspond to the operation of the sliding device 100, which can prevent the base unit B from flowing.

[0167] In addition, through the additional structure of the support plate unit 400, the sliding motor 14 of the sliding device 100, the motion drive unit 50 of the folding unit, the sliding change part 15 and the motion limit sensor part 17 are locked in their original positions, and the power transmission system can be clearly defined.

[0168] Furthermore, the connecting space 310, corresponding to the outward folding operation, prevents the moving unit 20 from interfering with the work plate unit 300.

[0169] Although preferred embodiments of the invention have been described with reference to the accompanying drawings, those skilled in the art will make various modifications or changes to the invention without departing from the scope and spirit of the invention as disclosed in the appended claims.
