[0017] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, which illustrate various embodiments. However, the present disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. The same reference numerals refer to the same elements throughout.

[0018] It will be understood that when an element or layer is referred to as being "on" another element or layer, it includes not only the case where it is directly disposed on the other element or layer, but also the case where there is an intervening element or layer therebetween. Conversely, when an element or layer is referred to as being "directly disposed" on another element or layer, or "disposed on" another element or layer, it means that there is no intervening layer or element therebetween.

[0019] For ease of description, spatial relative terms, such as “below,” “under,” “down,” “above,” and “up,” are used herein to describe the relationship between one element or feature and another, as illustrated in the accompanying drawings. It will be understood that spatial relative terms are intended to encompass different orientations of the apparatus in use or operation, other than those depicted in the accompanying drawings.

[0020] It will be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, components, and / or sections, these elements, components, and / or sections should not be limited by these terms. These terms are used only to distinguish one element, component, or section from another. Therefore, the first element, component, or section discussed below may be referred to as the second element, component, or section without departing from the teachings of this disclosure.

[0021] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both singular and plural forms unless the context clearly indicates otherwise. Thus, a reference to the element “the” following a reference to the element “a” in the claims includes one element and multiple elements. For example, “a element” has the same meaning as “at least one element” unless the context clearly indicates otherwise. “At least one” should not be construed as limited to “a.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated enumerated items. It will be further understood that the terms “comprising” and / or “including,” when used in this specification, indicate the presence of the described features, areas, integers, steps, operations, elements, components, and / or groups thereof, but do not exclude the presence or addition of one or more other features, areas, integers, steps, operations, elements, components, and / or groups thereof.

[0022] Furthermore, relative terms, such as “below” or “bottom” and “above” or “top”, can be used herein to describe the relationship between one element and another illustrated in the figures. It will be understood that relative terms are intended to encompass different orientations of the device other than those depicted in the figures. For example, if a device in a figure is flipped, an element described as being “below” the other elements will be oriented “above” the other elements. Thus, depending on the specific orientation of the figure, the term “below” can encompass both “below” and “above” orientations. Similarly, if a device in a figure is flipped, an element described as being “below” or “under” the other elements will be oriented “above” the other elements. Thus, the term “below” or “under” can encompass both “above” and “below” orientations.

[0023] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will be further understood that terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with their meaning in the relevant technical context and in the context of this disclosure, and shall not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0024] Referring to the cross-sectional views, which are schematic diagrams of idealized embodiments, embodiments are described herein. Therefore, variations in the illustrated shapes are contemplated due to, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the areas illustrated herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, areas illustrated or described as flat may generally have rough and / or non-linear characteristics. Furthermore, illustrated sharp corners may be rounded. Therefore, the areas illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate precise shapes of the areas and are not intended to limit the scope of the claims.

[0025] In the following description, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0026] Figure 1 This is a perspective view of a platform mobile device according to an embodiment of the present disclosure. Figure 2 for Figure 1 The side view of the platform moving device is shown in the example. Figure 3 for Figure 1 The diagram shows a plan view of the mobile platform.

[0027] See Figure 1 One embodiment of the platform mobile device SMD may include a base component BSP and a transmission component CRP. The transmission component CRP may include a platform TBL and multiple air injection components ANZ. In one embodiment, for example, the platform TBL may have a cuboid shape. The upper surface of the platform TBL may have a rectangular shape, having a long side extending in a first direction DR1 and a short side extending in a second direction DR2 intersecting the first direction DR1. However, embodiments of the present disclosure are not limited thereto, and the platform TBL may have various shapes.

[0028] In the following text, the direction substantially perpendicular to the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. In this specification, the terms "when viewed in a plane" or "in a plan view" may be defined as the state when viewed in the third direction DR3.

[0029] The upper surface of the test bench TBL may include multiple loading components LGR. The loading components LGR may be arranged in a first direction DR1 and a second direction DR2. In one embodiment, for example, as... Figure 1 As shown in the example, the loading component LGR has a rectangular shape, but the shape of the loading component LGR is not limited to this.

[0030] In one embodiment, for example, the test bench TBL may include granite, but is not limited thereto. The test bench TBL may also include carbon, ceramic, or alloy materials, etc.

[0031] Multiple load LODs can be mounted on the rack TBL. Each load LOD can be individually mounted on a corresponding load component LGR. In one embodiment, for example, a load LOD can be a display panel or a window, but is not limited thereto.

[0032] The load LOD can be moved while mounted on the bench TBL. See also Figures 5A-5C Describe the movement of the TBL bench in detail.

[0033] See Figures 1-3 The air injection component ANZ can be disposed on the lower surface of the test bench TBL and on two opposite side surfaces of the test bench TBL in the second direction DR2, and the lower surface and side surfaces can face the inner surface of the base component BSP. In one embodiment, for example, as Figures 1-3 As illustrated, four air injection components ANZ are disposed on the lower surface of the test bench TBL, and the four air injection components ANZ are disposed on two opposite side surfaces of the test bench TBL in the second direction DR2. However, the number of air injection components ANZ is not limited to this.

[0034] In one embodiment, for example, the air injection component ANZ may have a column shape. However, the air injection component ANZ is not limited to this and may have various shapes.

[0035] Air can be ejected or sprayed from the surface of the air jet component ANZ in a direction facing the base component BSP, which will be described later. Because air is sprayed through the air jet component ANZ, the test bench TBL does not need to contact the base component BSP. The air jetting from the air jet component ANZ will be discussed later. Figure 4 To describe in more detail.

[0036] When viewed in a plane, the base component BSP can have a quadrilateral shape. When viewed in a third direction DR3, the base component BSP can have a rectangular partial shape, having a long side extending in the first direction DR1 and a short side extending in the second direction DR2. However, the shape of the base component BSP is not limited to these, and the base component BSP can have various shapes.

[0037] The guide groove GGR can be defined in the upper surface of the base component BSP. The guide groove GGR can extend from the upper surface of the base component BSP toward the lower surface of the base component BSP. In one embodiment, for example, when in such... Figure 2 When viewed in the first direction DR1, the inner surface of the defining guide groove GGR of the base component BSP can have a shape corresponding to a rectangle. The guide groove GGR can extend in the first direction DR1.

[0038] The transmission component CRP can be disposed inside the guide groove GGR. The transmission component CRP can move along the guide groove GGR in the first direction DR1. When the transmission component CRP moves, the load LOD loaded on the transmission component CRP can move in the first direction DR1.

[0039] The test bench TBL and the air jet component ANZ can be housed in or inside the guide groove GGR. In the following, the side surface of the air jet component ANZ facing the inner surface of the base component BSP can be defined as a single side surface of the air jet component ANZ.

[0040] One side surface of the air injection component ANZ can inject air toward the inner surface of the base component BSP. When the air injection component ANZ injects air, the test bench TBL can be spaced apart from the inner surface of the base component BSP. The transfer component CRP does not contact the inner surface of the base component BSP, therefore, no friction occurs when the transfer component CRP moves along the guide groove GGR in the first direction DR1. See below. Figure 4 The air injection from the ANZ air injection unit is described in detail.

[0041] Figure 4 For along Figure 1 The cross-sectional view of line I-I' is shown in the example.

[0042] In particular, Figure 4 for Figure 1 A cross-sectional view of one of the air injection components ANZ illustrated in the figure.

[0043] For ease of illustration and description, Figure 4 Only a portion of the benchtop TBL and a portion of the base component BSP are shown.

[0044] Figure 4 The bench TBL and base component BSP illustrated in the figure are Figure 1 The bench TBL and base component BSP illustrated herein are identical, therefore any repeated detailed descriptions will be omitted or simplified.

[0045] For example, see Figure 4 describe Figure 1 The example illustrates one of the multiple air injection components ANZ, but essentially, the description of one air injection component ANZ can be similarly applied to the other air injection components ANZ.

[0046] See Figures 1-4 In one embodiment, the air injection component ANZ may include an upper plate UPT, a lower plate BPT, an airbag APT, a first tube PIP1, and a motor component MTP.

[0047] The upper plate UPT can be disposed on the lower surface of the bench TBL. In one embodiment, for example, the upper plate UPT can have a disc-shaped shape, but is not limited thereto. The upper plate UPT can have various shapes.

[0048] The lower plate (BPT) can be disposed below the upper plate (UPT). The lower plate (BPT) can be disposed between the upper plate (UPT) and the base component (BSP). In one embodiment, for example, the lower plate (BPT) can have a disc-shaped shape, but is not limited thereto. The lower plate (BPT) can have various shapes.

[0049] The lower plate BPT may include a support plate SPL and a support member SPT. The support plate SPL may be disposed below the upper plate UPT. The support plate SPL may be disposed between the upper plate UPT and the base member BSP. The support plate SPL may be spaced a predetermined distance from the base member BSP on the third direction DR3. The support plate SPL may be disposed below the support member SPT. In one embodiment, for example, the support plate SPL may have a disc-shaped shape, but is not limited thereto. The support plate SPL may have various shapes.

[0050] The injection port APP can be defined within the support plate SPL. The injection port APP can extend along the third direction DR3 from the upper surface of the support plate SPL toward the lower surface of the support plate SPL. In one embodiment, for example, the injection port APP can have the shape of an orifice tube and have a variable diameter. However, one embodiment of this disclosure is not limited thereto, and the injection port APP can be of the porous vacuum chuck type. See later. Figures 7A to 7C A detailed description of the jet port APP according to another embodiment.

[0051] In one embodiment, for example, as Figure 4 As illustrated, a single injection port APP is defined within an air injection component ANZ, but the number of injection port APPs is not limited to this. Multiple injection port APPs can be defined. See also... Figure 7A It is described in detail.

[0052] A support member SPT may be disposed on the upper surface of a support plate SPL. The support member SPT may extend from the upper surface of the support plate SPL toward the upper plate UPT. In one embodiment, the support member SPT and the support plate SPL may be integrally formed as a single, inseparable component.

[0053] Although not shown, the support member SPT can have a hollow cylindrical shape. Although not shown, when viewed in a plane, the support member SPT can surround the injection port APP.

[0054] An airbag APT can be positioned between the upper plate (UPT) and the lower plate (BPT). The airbag APT can be connected to both the upper plate (UPT) and the lower plate (BPT). The space between the upper plate (UPT) and the lower plate (BPT) can be surrounded by the airbag APT. The space between the upper plate (UPT) and the lower plate (BPT) can be sealed by the airbag APT. The airbag APT can define a containment space (CSP) between the upper plate (UPT) and the lower plate (BPT).

[0055] In one embodiment, for example, the receiving space CSP and the injection port APP may be continuously defined or connected to each other. The injection port APP may be defined below the receiving space CSP. The injection port APP may be adjacent to the upper surface of the base member BSP than the receiving space CSP. However, this is illustrated as an example, and the injection port APP and the receiving space CSP may be separate from each other. See also Figure 7A and Figure 7B It is described in detail.

[0056] The first tube PIP1 can pass through the upper plate UPT and extend into the receiving space CSP. A portion of the first tube PIP1 can be disposed within the receiving space CSP. The first tube PIP1 can be connected to a pump (not shown) and inject air into the receiving space CSP. When air is injected into the receiving space CSP, the airbag APT can inflate.

[0057] When air is injected into the airbag APT, the air can exert pressure on the test bench TBL and the upper plate UPT in the opposite direction to the direction of gravity acting on the test bench TBL and the upper plate UPT. Therefore, the upper plate UPT and the test bench TBL can move in the third direction DR3 due to the air injected into the airbag APT.

[0058] Air flowing into the containment space CSP can partially flow out to the outside via the injection port APP. The air pressure at the inlet of the injection port APP can be lower than the air pressure at the outlet of the injection port APP. The inlet of the injection port APP can be defined as a portion of the upper surface of the adjacent support plate SPL. The outlet of the injection port APP can be defined as a portion of the lower surface of the adjacent support plate SPL. The air flowing out via the injection port APP can exert pressure on the inner surface of the base component BSP. Therefore, a force can be applied to the air injection component ANZ in a direction parallel to the third direction DR3. The air injection component ANZ can be spaced apart from the inner surface of the base component BSP by this force.

[0059] The motor component MTP can be positioned between the upper plate UPT and the lower plate BPT. The motor component MTP can be positioned within or inside the receiving space CSP. The motor component MTP can be surrounded by the airbag APT. The motor component MTP can be connected to both the upper plate UPT and the lower plate BPT. The motor component MTP can be positioned on the lower surface of the upper plate UPT. The motor component MTP can be connected to the support component SPT of the lower plate BPT. The motor component MTP can control the distance between the upper plate UPT and the lower plate BPT. See later. Figures 5A-5C Describe in detail the distance between the upper plate UPT and the lower plate BPT, which are controlled by the motor component MTP.

[0060] The motor component MTP may include a yoke YK, a damper CS, a magnet MG, a coil COL, and wires ELL. The yoke YK may be disposed between the upper plate UPT and the lower plate BPT. The yoke YK may be disposed on the lower surface of the upper plate UPT.

[0061] In one embodiment, for example, the yoke YK may include Fe. However, one embodiment of this disclosure is not limited thereto, and the yoke YK may include other materials. The yoke YK can be used as the path through which the magnetic field lines of the magnet MG, described later, pass.

[0062] The magnetic yoke YK may include a first magnetic yoke YK1, a second magnetic yoke YK2, and a third magnetic yoke YK3. The first magnetic yoke YK1 may be disposed on the lower surface of the upper plate UPT. Although not illustrated, for example, the first magnetic yoke YK1 may have a disc-shaped shape. However, embodiments of the present disclosure are not limited thereto, and the first magnetic yoke YK1 may have other shapes.

[0063] The second magnetic yoke YK2 can be disposed between the first magnetic yoke YK1 and the lower plate BPT. The second magnetic yoke YK2 can be disposed on the lower surface of the first magnetic yoke YK1. Although not illustrated, the second magnetic yoke YK2 can have a cylindrical shape.

[0064] The receiving groove CGR may be defined by the second magnetic yoke YK2. The receiving groove CGR may be defined inside the second magnetic yoke YK2. Although not illustrated, the receiving groove CGR may have a shape corresponding to a cylinder. However, the shape of the receiving groove CGR is not limited to this.

[0065] A magnet MG can be disposed in a receiving groove CGR. The magnet MG can be disposed on the lower surface of the first yoke YK1. The magnet MG can include a first magnetic pole NP and a second magnetic pole SP. The first magnetic pole NP can be a north pole (N). The second magnetic pole SP can be a south pole (S). In one embodiment, for example, the second magnetic pole SP can be disposed below the first magnetic pole NP. The first magnetic pole NP can be disposed on the lower surface of the first yoke YK1, and the second magnetic pole SP can face the lower plate BPT. However, this is illustrated as an example, and the first magnetic pole NP can be disposed below the second magnetic pole SP.

[0066] The damper CS can be disposed in the receiving slot CGR. The damper CS can be disposed between the coil COL and the first yoke YK1, which will be described later, based on the third direction DR3. Although not illustrated, the damper CS can surround the periphery of the magnet MG. The damper CS can support the coil COL when no current is applied to the coil COL, which will be described later.

[0067] The third magnetic yoke YK3 can be disposed in the receiving groove CGR. The third magnetic yoke YK3 can be disposed between the magnet MG and the lower plate BPT. The third magnetic yoke YK3 can be disposed on the lower surface of the magnet MG facing the lower plate BPT.

[0068] The coil COL can be connected to the support member SPT of the lower plate BPT. The coil COL can be disposed on the upper surface of the support member SPT. The coil COL can have a solenoid shape. The magnet MG and the third yoke YK3 can be surrounded by the coil COL. Although not illustrated, the coil COL can have, for example, a hollow cylindrical shape, but it can have a hollow square prism shape and is not limited thereto.

[0069] The wire ELL can pass through the lower plate BPT to be connected to the coil COL. Although not illustrated, the wire ELL can apply current from an external power source to the coil COL.

[0070] When an electric current flows through the wire ELL in the coil COL, a Lorentz force can act on the coil COL. The Lorentz force is generated by the magnetic field of the magnet MG and the current flowing in the coil COL. The Lorentz force can be defined as the force exerted on a conductor by the force acting on the moving charge when an electric current flows through it in a magnetic field.

[0071] The direction of the Lorentz force follows Fleming's left-hand law. Fleming's left-hand law can be defined as the law that determines the direction of the force acting on a conductor given the direction of the magnetic field and the direction of the flowing current. The direction of the Lorentz force can vary based on the direction of the magnetic field of the magnet MG and the direction of the current flowing in the coil COL. Accordingly, the direction of movement of the coil COL can change, and therefore the area of ​​the magnet MG surrounded by the coil COL can increase or decrease. The gap between the lower plate BPT connected to the coil COL and the upper plate UPT connected to the magnet MG is variable.

[0072] The gravity acting on the test bench TBL and the upper plate UPT can be compensated by the pressure of the air flowing into the containment space CSP. Accordingly, since the Lorentz force is relatively smaller than gravity, the gap between the lower surface of the upper plate UPT and the inner surface of the base component BSP can be easily or effectively controlled. That is, due to the Lorentz force, the gap between the lower surface of the upper plate UPT and the upper surface of the lower plate BPT can be finely controlled. Because the gap between the lower surface of the upper plate UPT and the upper surface of the lower plate BPT can be finely controlled, when the transfer component CRP (see...)... Figure 1 When moving along the guide groove GGR, the transmission component CRP can be easily compensated (see...). Figure 1 Errors in the movement path. See also Figures 5A-5C Detailed description of error compensation via the ANZ air injection component.

[0073] Figures 2-4 An example is an air injection component ANZ disposed on the lower surface of the test bench TBL, but the above description can also be similarly applied to other air injection components ANZ disposed on the lower surface of the test bench TBL and air injection components ANZ disposed on the opposite side surfaces of the test bench TBL in the first direction DR1.

[0074] Figures 5A-5C For example Figure 1 The image shows a view illustrating the movement of the transmission component. Figure 6 This is a view used to illustrate errors in the movement path of the compensation transmission component.

[0075] In particular, Figure 5A This is a floor plan. Figure 5B This is a cross-sectional view taken along line II-II', and Figure 5C This is a cross-sectional view taken along line III-III'.

[0076] For ease of illustration and description, Figure 5A Only a portion of the base component BSP is shown.

[0077] For ease of illustration and description, Figure 5A in, omit Figure 1 Load LOD and Figure 4 The first tube PIP1 and the wire ELL.

[0078] Figures 5A-5C The bench TBL, air injection component ANZ, and base component BSP illustrated in the figure are... Figures 1-4 The bench TBL, air injection component ANZ, and base component BSP illustrated herein are identical, therefore any repeated detailed descriptions will be omitted or simplified.

[0079] See Figure 1 and Figure 5A Although not illustrated, the stage moving device SMD may further include sensors. The sensors can measure the distance between the lower surface of the stage TBL and the inner surface of the base component BSP, as well as the distance between the side surface of the stage TBL and the inner surface of the base component BSP. Furthermore, the sensors can measure the direction of movement of the stage TBL.

[0080] See Figure 5A and Figure 5B The transmission component CRP can move according to set information. The set information may include information about the direction of movement. In one embodiment, for example, the transmission component CRP moves in a first direction DR1, but the direction of movement of the transmission component CRP is not limited to this.

[0081] When the transmission component CRP moves, air can flow into the receiving space CSP through the first pipe PIP1 (see...). Figure 4 The air flowing into the containment space CSP can partially flow out to the injection port APP (see...). Figure 4 ).

[0082] Because from Figure 4 The air ejected by the injection port APP illustrated in the diagram can be transmitted without contacting the inner surface of the base component BSP that defines the guide groove GGR. Therefore, frictional forces do not act between the inner surfaces of the transmission component CRP and the base component BSP.

[0083] The configured information may further include information about errors in the direction of movement. For example, foreign matter (DST) can accumulate on the inner surface of the base component (BSP). DST can protrude from the inner surface of the base component (BSP). When the transfer component (CRP) passes over DST, the movement path of the transfer component (CRP) may be altered due to the DST. Therefore, errors may occur in the movement path of the test bench (TBL). The configured information may include information about the errors caused by DST.

[0084] The configured information may include information for compensating for errors. According to one embodiment of this disclosure, the transmission component CRP can compensate for errors in the movement path based on the configured information. In one embodiment, when the transmission component CRP passes a foreign object DST, current can be applied to the coil COL via the wire ELL to compensate for errors in the movement path using the configured information.

[0085] When current flows in coil COL, a Lorentz force is generated in coil COL by the current flowing in coil COL and the magnetic field of magnet MG. The Lorentz force can act on coil COL in a direction parallel to the second direction DR2. The Lorentz force can also act on coil COL in a direction toward the receiving groove CGR. Therefore, coil COL can move toward the receiving groove CGR. The area of ​​magnet MG surrounded by coil COL can increase.

[0086] When the coil COL moves, the lower plate BPT connected to the coil COL can move in the opposite direction to the second direction DR2. Accordingly, since the distance between the upper surface of the lower plate BPT and the lower surface of the upper plate UPT decreases, the motor component MTP can compensate for the error caused by the foreign object DST. Therefore, the foreign object DST does not change the movement path of the test bench TBL.

[0087] Furthermore, when the housing space CSP is filled with air, the air in the housing space CSP can exert pressure on the upper plate UPT. The upper plate UPT can transmit the force caused by the pressure to the test bench TBL. Accordingly, the force caused by the air pressure and the external force acting on the test bench TBL can cancel each other out. When the external force acting on the test bench TBL is canceled out, the motor component MTP can accurately compensate for errors in the movement path of the test bench TBL by using the Lorentz force. Therefore, the motor component MTP can accurately and easily compensate for errors in the movement path of the transmission component CRP.

[0088] See Figure 5A and Figure 5C The slot RG can be defined within the inner surface of the base component BSP. The slot RG can be recessed from the inner surface of the base component BSP. Therefore, when the transmission component CRP passes through the slot RG, the movement path of the transmission component CRP changes, which may cause errors in the movement path of the transmission component CRP.

[0089] In one embodiment, current can be applied to coil COL to compensate for errors using pre-defined information. The applied current is... Figure 5C The direction of flow in the middle can be related to the applied current. Figure 5B The flow direction is opposite.

[0090] The air injection component ANZ can compensate for errors based on set information. In one embodiment, when current is applied to the coil COL, a Lorentz force can be generated by the magnetic field of the magnet MG and the current in the coil COL. This Lorentz force can act on the coil COL in a direction opposite to the second direction DR2. Therefore, the coil COL can move in a direction opposite to the second direction DR2. The coil COL can be moved to expose itself from the receiving groove CGR to the outside. The area of ​​the magnet MG surrounded by the coil COL can be reduced.

[0091] When the coil COL moves in the opposite direction to the second direction DR2, the lower plate BPT connected to the coil COL can also move in the opposite direction to DR2. As the lower plate BPT moves in the opposite direction to DR2, the distance between the lower surface of the upper plate UPT and the upper surface of the lower plate BPT can increase. The motor component MTP can compensate for the error caused by the slot GR.

[0092] In this configuration, the forces caused by air pressure and the external forces acting on the test bench TBL can cancel each other out as air enters the containment space CSP. Therefore, the motor component MTP can precisely compensate for errors in the movement path of the test bench TBL, and consequently, the transmission component CRP can move accurately and easily.

[0093] Figures 5A-5C An example is an air injection component ANZ disposed on opposite side surfaces of the test bench TBL in the second direction DR2, but the embodiments disclosed herein are not limited thereto. The above description can also be similarly applied to an air injection component ANZ disposed on the lower surface of the test bench TBL.

[0094] See Figure 5B and Figure 5C The compensation for errors occurring in the plane defined by the first direction DR1 and the second direction DR2 is described, but the embodiments of this disclosure are not limited thereto.

[0095] Errors may occur in the movement path of the transmission component CRP on the third-direction DR3. For example, when foreign objects or grooves are present on the inner surface of the defined guide groove GGR of the base component BSP, errors may occur in the movement path on the third-direction DR3. In this case, the air injection component ANZ provided on the lower surface of the test bench TBL can be energized according to the set information and compensate for the errors in the movement path on the third-direction DR3.

[0096] See Figure 6Errors in the movement path of the transmission component CRP may include rotation at a predetermined angle relative to a first rotation axis RX1 parallel to the first direction DR1. For example, when viewed in a plane, the height of the left side of the test bench TBL relative to the first rotation axis RX1 may be less than the height of the right side of the test bench TBL.

[0097] In this configuration, the air jet component ANZ, located on the lower surface of the test bench TBL, can receive current according to pre-set information. The current-receiving coil COL can move. In one embodiment, for example, relative to the first rotation axis RX1, the coil COL of the air jet component ANZ, located on the lower left surface of the test bench TBL, can move in a direction toward the outside of the receiving groove CGR. The coil COL of the air jet component ANZ, located on the lower right surface of the test bench TBL, can move in a direction toward the inside of the receiving groove CGR. Therefore, errors in the movement path of the test bench TBL can be compensated for.

[0098] Errors in the movement path of the transmission component CRP may include errors due to rotation at a predetermined angle relative to a second rotation axis RX2 parallel to the second direction DR2. For example, when viewed in a plane, the height of the upper portion of the test bench TBL may be less than the height of the lower portion of the test bench TBL relative to the second rotation axis RX2.

[0099] In this configuration, the air jet component ANZ, mounted on the lower surface of the test bench TBL, receives current according to pre-set information. The current-receiving coil COL can move. For example, relative to the second rotation axis RX2, the coil COL of the air jet component ANZ mounted on the upper portion of the test bench TBL can move in a direction toward the outside of the receiving groove CGR. The coil COL of the air jet component ANZ mounted on the lower portion of the test bench TBL can move in a direction toward the inside of the receiving groove CGR. Therefore, errors in the movement path of the test bench TBL can be compensated for.

[0100] Furthermore, when the air bladder APT of the air injection component ANZ is filled with air, the force caused by the air pressure and the external forces acting on the test bench TBL, including gravity, can cancel each other out. Therefore, the error in the movement path of the test bench TBL can be accurately compensated by the motor component MTP. Consequently, the transmission component CRP can be moved accurately and easily.

[0101] Figures 7A to 7C A view illustrating a platform mobile device according to another embodiment of the present disclosure.

[0102] See Figures 7A to 7C The description of the mobile device will focus on the air injection components ANZa, ANZb and ANZc.

[0103] In particular, Figures 7A to 7C For along Figure 1 The cross-sectional view of line I-I' is shown in the example.

[0104] For ease of illustration and description, Figures 7A to 7C Only examples are shown in Figure 1 The example shown is a portion of the bench TBL and a portion of the base component BSP.

[0105] Figures 7A to 7C The bench TBL, base component BSP, motor component MTP, and airbag APT illustrated in the figure Figure 4 The bench TBL, base component BSP, motor component MTP and airbag APT illustrated herein are identical, therefore any repeated detailed descriptions will be omitted or simplified.

[0106] See Figure 7A In one embodiment, multiple injection ports APP can be defined in the support plate SPLa of the lower plate BPTa. Figure 7A The app can connect to each injection port. Figure 4 The injection port APPs are basically the same. When viewed in the second direction DR2, the injection port APPs can be aligned in the first direction DR1.

[0107] Air flowing into the containment space CSP via the first pipe PIP1 can flow out to the outside via each injection port APP. In one embodiment, for example, each injection port APP can have an orifice-like shape. The air pressure at the inlet of each injection port APP can be lower than the air pressure at the outlet of each injection port APP. The air flowing out via each injection port APP can apply pressure to the base component BSP. Therefore, the air injection component ANZa can be spaced apart from the inner surface of the base component BSP.

[0108] See Figure 7B In one embodiment, the air injection component ANZb may further include a second tube PIP2 and a spraying component AST. The spraying component AST may be disposed below the lower plate BPTb. The spraying component AST may be disposed on the lower surface of the lower plate BPTb. The injection port APPa may be defined in the spraying component AST. The injection port APPa may not be defined in the support plate SPLb. In one embodiment, for example, the injection port APPa may have an orifice-like shape.

[0109] The injection port APPa and the receiving space CSP can be separated from each other. The injection port APPa and the receiving space CSP can be blocked from each other by the lower plate BPTb. Therefore, the air flowing into the receiving space CSP from the first pipe PIP1 can not flow out to the injection port APPa.

[0110] The second pipe PIP2 can be connected to the spraying component AST. The second pipe PIP2 allows air to flow from the pump (not shown) into the spraying component AST. The air flowing into the spraying component AST can flow out to the outside via the injection port APPa. The air flowing out to the outside can apply pressure to the inner surface of the base component BSP, and the air injection component ANZb can be spaced apart from the base component BSP.

[0111] See Figure 7C In one embodiment, the injection port ASTA can be a porous chuck type (e.g., a porous vacuum chuck type). The porous chuck type can be defined as one in which air flows out through a small opening (not illustrated). When air flows into the injection port ASTA connected to the second tube PIP2, the air can flow out through the small opening (not illustrated). The outflowing air can apply pressure to the inner surface of the base component BSP. Therefore, the air injection component ANZc can be spaced apart from the base component BSP.

[0112] According to one embodiment of this disclosure, an air jetting component disposed on the lower and side surfaces of a platform carrying a display panel may include an upper plate connected to the platform, a lower plate disposed below the upper plate, a motor component disposed between the upper and lower plates, and an air bladder surrounding the motor component. The air bladder is disposed between the upper and lower plates, and when the air bladder is filled with air, the force caused by the air pressure and the external force applied to the platform can cancel each other out. Therefore, the motor component can easily compensate for errors occurring in multiple directions along the movement path of the platform.

[0113] This disclosure should not be construed as limiting itself to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art.

[0114] Although this disclosure has been specifically shown and described with reference to embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made therein without departing from the spirit or scope of this disclosure as defined in the claims.
