Detailed Implementation

[0028] The invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are illustrated. However, the invention 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 this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The same reference numerals throughout denote the same elements.

[0029] It will be understood that when an element is referred to as being "on" another element, it can be directly on the other element, or there can be an intermediary element between them. Conversely, when an element is referred to as being "directly" on another element, there is no intermediary element.

[0030] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or section from another. Therefore, without departing from the teachings herein, “first element,” “first component,” “first region,” “first layer,” or “first section” discussed below may be referred to as a second element, second component, second region, second layer, or second section.

[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a,” “an,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both the singular and the plural unless the context clearly indicates otherwise. Thus, reference to “a” element in a claim followed by “the” element 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 limiting “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will also be understood that, when used in this specification, the terms “comprises” and / or “comprising” or “includes” and / or “including” specify the presence of the stated feature, region, integral, step, operation, element, and / or component, but do not exclude the presence or addition of one or more other features, regions, integrals, steps, operations, elements, components, and / or groups thereof.

[0032] Furthermore, relative terms such as “below” or “bottom” and “above” or “top” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. It will be understood that, in addition to the orientations shown in the drawings, the relative terms are intended to encompass different orientations of the devices. For example, if a device in one of the drawings is flipped, an element described as being “below” the other element will subsequently be oriented “above” the other element. Thus, depending on the specific orientation of the drawing, the term “below” can encompass both “below” and “above” orientations. Similarly, if a device in one of the drawings is flipped, an element described as being “below” or “under” the other element will subsequently be oriented “above” the other element. Thus, the term “below” or “under” can encompass both “above” and “below” orientations.

[0033] Given the measurements discussed and the errors associated with the measurement of a particular quantity (i.e., limitations of the measurement system), the terms “about” or “approximately” as used herein include the stated value and mean within an acceptable deviation range of the particular value as determined by one of ordinary skill in the art. For example, “about” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value.

[0034] 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 common dictionaries) shall be interpreted as having the same meaning as they have in the relevant field and in the context of this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0035] Embodiments are described herein with reference to cross-sectional views as schematic representations of idealized embodiments. Thus, variations in the illustrated shapes should be anticipated, for example, due to manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but should include, for example, deviations in shape due to manufacturing processes. For instance, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, sharp corners shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to represent the precise shapes of the regions, nor are they intended to limit the scope of the claims.

In an embodiment, for example, the bridging mounting bracket 230 may be located between the mask mounting bracket 130 of the first mask mounting portion 101 and the mask mounting bracket 130 of the second mask mounting portion 102.

[0101] The upper surface of the bridging mount 230 can be located below the upper surface of the mask mount 130. The bridging strip 30 can be located below the mask strip 20.

[0102] In one embodiment, for example, the upper surface of the bridging mounting bracket 230 may be located below the upper surface of the mask mounting bracket 130 of the first mask mounting section 101.

[0103] In one embodiment, for example, the bridging strip 30 may be located below the front mask strip 2001. In another embodiment, for example, the bridging strip 30 may be located at the rear edge 22L2 of the front mask strip 2001 (see...). Figure 2 Below. In an embodiment, for example, the front mask strip 2001 may be located at the front edge 32L1 of the bridging strip 30 (see below). Figure 3 )superior.

[0104] In one embodiment, for example, the upper surface of the bridging mounting bracket 230 may be located below the upper surface of the mask mounting bracket 130 of the second mask mounting section 102.

[0105] In one embodiment, for example, the bridging strip 30 may be located below the rear mask strip 2002. In another embodiment, for example, the bridging strip 30 may be located at the leading edge 22L1 of the rear mask strip 2002 (see...). Figure 2 Below. In an embodiment, for example, the rear mask strip 2002 may be located at the rear edge 32L2 of the bridging strip 30 (see below). Figure 3 )superior.

[0106] The bridging mount 230 may include a bridging mount body 231. The bridging mount body 231 may be connected to or coupled to the bridging mount leg 220.

[0107] In one embodiment, for example, the bridging mount 230 may be connected to or coupled to the upper end of the bridging mount leg 220. In another embodiment, for example, the bridging mount 230 may be shaped to extend upward from the bridging mount leg 220.

[0108] The bridging mount 230 may include a bridging mount top 232. The bridging mount top 232 may define the upper surface of the bridging mount 230.

[0109] In one embodiment, for example, the bridging strip 30 may be disposed on the upper surface of the bridging mount top 232. In another embodiment, for example, the bridging strip 30 may be coupled to the upper surface of the bridging mount top 232.

[0110] The bridging mount top 232 may be connected to or coupled to the bridging mount body 231. In some embodiments, for example, the bridging mount top 232 may extend from the bridging mount body 231. In some embodiments, for example, the bridging mount top 232 may be integrally formed with the bridging mount body 231 as a single, inseparable part.

[0111] The bridging mount 230 may include a bridging mount magnet 233. The bridging mount magnet 233 may be connected to, coupled to, or housed in at least one selected from the bridging mount body 231 and the bridging mount top 232.

[0112] In one implementation, for example, the bridging mount magnet 233 may be movably coupled to at least one selected from the bridging mount body 231 and the bridging mount top 232.

[0113] In one embodiment, for example, the bridging mount magnet 233 may be movably coupled to the bridging mount body 231. In another embodiment, for example, the bridging mount magnet 233 may be located below the top 232 of the bridging mount.

[0114] The bridging mount magnet 233 can generate a magnetic field. In one embodiment, the bridging mount magnet 233 may include, for example, a permanent magnet. In another embodiment, for example, the bridging mount magnet 233 may include an electromagnet.

[0115] At least one suction hole (not shown) may be defined or formed on the upper surface of the bridging mount top 232. In an embodiment, the suction hole (not shown) formed on the upper surface of the bridging mount top 232 can draw in air.

[0116] When air is drawn in through a suction hole (not shown) formed on the upper surface of the bridging mount top 232, the bridging strip 30 can contact or connect to the bridging mount top 232. The connection force between the bridging strip 30 and the bridging mount top 232 can be set differently depending on the suction force of the suction hole (not shown).

[0117] The bridging mount 230 can be movably connected to the bridging mount base 210. In one embodiment, for example, the bridging mount 230 can be connected to the bridging mount base 210 via bridging mount legs 220 to enable its vertical movement.

[0118] Figure 7 It shows moving upwards Figure 5 The bridging mounting bracket shown.

[0119] refer to Figure 6 and Figure 7 The bridging mount 230 can be moved upward. In one embodiment, for example, the bridging mount 230 can be moved upward relative to the bridging mount base 210.

[0120] In one embodiment, for example, the upper end of the bridging mounting leg 220 may be moved upward relative to the bridging mounting base 210. In another embodiment, for example, the upper end of the bridging mounting leg 220 may be moved upward relative to the lower end of the bridging mounting leg 220.

[0121] When the bridging mount 230 moves upward, the bridging strip 30 can approach the mask strip 20. In an embodiment, for example, when the bridging mount 230 moves upward, the bridging strip 30 can contact the mask strip 20.

[0122] The bridging mount magnet 233 can provide magnetic flux to the bridging mount top 232. At least a portion of the magnetic flux provided to the bridging mount top 232 can be incident on the bridging strip 30.

[0123] The magnetic flux supplied to the top 232 of the bridging mount can be set differently. In one embodiment, for example, the distance between the bridging mount magnet 233 and the top 232 of the bridging mount can be adjusted.

[0124] In one implementation, for example, when the bridging mount magnet 233 approaches or moves toward the bridging mount top 232 while the bridging mount magnet 233 is generating a magnetic field, the magnitude or intensity of the magnetic flux provided to the bridging mount top 232 can be increased.

[0125] In one implementation, for example, when the bridging mount magnet 233 moves away from the top 232 of the bridging mount while the bridging mount magnet 233 forms a magnetic field, the magnitude or intensity of the magnetic flux supplied to the top 232 of the bridging mount can be reduced.

[0126] In some implementations, for example, if the bridging mount magnet 233 includes an electromagnet, the current applied to the bridging mount magnet 233 can be controlled.

[0127] In an implementation, for example, if the bridging mount magnet 233 is an electromagnet, the magnitude or intensity of the magnetic flux supplied to the top 232 of the bridging mount can be increased if the current applied to the bridging mount magnet 233 increases.

[0128] In an implementation, for example, if the bridging mount magnet 233 is an electromagnet, if the current applied to the bridging mount magnet 233 decreases, the magnitude or intensity of the magnetic flux supplied to the top 232 of the bridging mount can be reduced.

[0129] The mask strip 20 and bridging strip 30 may comprise or be formed of a metallic material. In some embodiments, for example, the mask strip 20 and bridging strip 30 may comprise or be formed of a ferromagnetic material. In some embodiments, for example, the mask strip 20 and bridging strip 30 may comprise or be formed of an iron-containing material. In some embodiments, for example, the mask strip 20 and bridging strip 30 may comprise or be formed of a paramagnetic material.

[0130] A portion of the magnetic flux generated by the bridging mount magnet 233 can be transferred to the mask strip 20 and the bridging strip 30. The magnetic flux transferred to the mask strip 20 can induce a magnetic field in the mask strip 20. The magnetic flux transferred to the bridging strip 30 can induce a magnetic field in the bridging strip 30.

[0131] The mask strip 20 and the bridging mount magnet 233 can be magnetically connected to each other. The bridging strip 30 and the bridging mount magnet 233 can be magnetically connected to each other. The bridging strip 30 and the mask strip 20 can be magnetically connected to each other.

[0132] In other words, the bridging strip 30 and the mask strip 20 can be connected to the top 232 of the bridging mount. The extent to which the bridging strip 30 and the mask strip 20 are connected to the top 232 of the bridging mount can depend on the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20.

[0133] In an implementation, for example, the degree to which the bridging strip 30 and the mask strip 20 are connected to the top 232 of the bridging mount can be increased when the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 increases.

[0134] In one implementation, for example, when the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 decreases, the degree to which the bridging strip 30 and the mask strip 20 are connected to the top 232 of the bridging mount can be reduced.

[0135] In one implementation, for example, the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 can be set differently depending on the distance between the top 232 of the bridging mount and the magnet 233 of the bridging mount.

[0136] In some embodiments, for example, the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 can be set differently depending on the magnetic force of the bridging mount magnet 233. In embodiments where the bridging mount magnet 233 includes an electromagnet, the magnetic force of the bridging mount magnet 233 can be set differently depending on the magnitude of the current applied to the bridging mount magnet 233.

[0137] Figure 8 It shows Figure 7Part of it, in which the mask strip and bridging strip are welded while fixed to the bridging mounting part. Reference Figure 7 and Figure 8 The intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 can be increased.

[0138] In one embodiment, for example, the bridging mount magnet 233 may be moved upward. In another embodiment, for example, the bridging mount magnet 233 may be close to the top 232 of the bridging mount.

[0139] In some implementations, for example, if the bridging mount magnet 233 includes an electromagnet, the magnitude of the current applied to the bridging mount magnet 233 can be increased.

[0140] When the intensity of the magnetic flux applied to the bridging strip 30 and the mask strip 20 increases, the connection force between the bridging strip 30 and the mask strip 20 can increase. That is, the bridging strip 30 and the mask strip 20 can be fixed to the bridging mounting portion 200 by the magnetic force of the bridging mounting bracket magnet 233. In an embodiment, for example, the bridging strip 30 and the mask strip 20 can be brought into close contact with each other by the magnetic force of the bridging mounting bracket magnet 233.

[0141] With the bridging strip 30 and the mask strip 20 fixed to the bridging mounting part 200, the welding unit 350 (see...) Figure 10 The mask strip 20 can be welded to the bridging strip 30.

[0142] In one embodiment, for example, with the bridging strip 30 and the mask strip 20 fixed to the bridging mounting portion 200, a weld 40 may be formed in at least one of the mask strip 20 and the bridging strip 30. In another embodiment, for example, the weld 40 may be formed at the boundary between the mask strip 20 and the bridging strip 30.

[0143] In an embodiment, for example, with the bridging strip 30 and the mask strip 20 fixed to the bridging mounting portion 200, the welding unit 350 (see...) Figure 10 Weld 40 can be formed on the upper surface of mask strip 20.

[0144] In an implementation, for example, welding unit 350 (see...) Figure 10 At least one selected from heat and pressure can be applied to the mask strip 20 and the bridging strip 30. In an embodiment, for example, welding unit 350 (see...) Figure 10 Current and pressure can be applied to the mask strip 20 and the bridging strip 30.

[0145] In an implementation, for example, welding unit 350 (see...) Figure 10The bridging strip 30 can be connected to the mask strip 20 using a solid-state welding method. In an embodiment, for example, welding unit 350 (see...) Figure 10 An electron beam can be applied to the mask strip 20. In an embodiment, for example, the welding unit 350 (see...) Figure 10 The mask strip 20 can be connected to the bridging strip 30 by an electric arc discharge method.

[0146] In an implementation, for example, welding unit 350 (see...) Figure 10 A weld 40 can be formed on the upper surface of the mask strip 20 using a laser welding method. In an embodiment, for example, welding unit 350 (see...) Figure 10 The laser beam can be radiated onto the upper surface of the mask strip 20.

[0147] In one implementation, for example, the laser beam can radiate from the upper surface of the mask strip 20 to the region of the boundary between the mask strip 20 and the bridging strip 30.

[0148] In an implementation, for example, the rear edge 22L2 of the front mask strip 2001 (see...) Figure 2 ) and the front edge 32L1 of the bridging strip 30 (see Figure 3 A boundary can be formed between the front mask strip 2001 and the bridging strip 30.

[0149] In an implementation, for example, the front edge 22L1 of the rear mask strip 2002 (see...) Figure 2 ) and the rear edge 32L2 of the bridging strip 30 (see Figure 3 This can form the boundary between the back mask strip 2002 and the bridging strip 30.

[0150] The laser beam radiating onto the upper surface of the mask strip 20 can transfer heat to the mask strip 20 and the bridging strip 30. A portion of the mask strip 20 and a portion of the bridging strip 30 can be joined together by heating, melting, and then hardening.

[0151] The thickness of the mask strip 20 may differ from the thickness of the bridging strip 30. In some embodiments, for example, the thickness of the bridging strip 30 may be greater than the thickness of the mask strip 20. In some embodiments, for example, the thickness of the bridging strip 30 may be two or more times the thickness of the mask strip 20.

[0152] Figure 9 Detailed illustration Figure 5 The mask mounting bracket shown.

[0153] refer to Figure 9 An embodiment of the mask mounting bracket 130 may include a mask mounting bracket body 131. The mask mounting bracket body 131 may be coupled to or connected to the mask mounting legs 120 (see...). Figure 5).

[0154] The mask mounting bracket 130 may include a mask mounting bracket top 132. The mask mounting bracket top 132 may form the upper surface of the mask mounting bracket 130.

[0155] The top 132 of the mask mounting bracket may include or be formed of a material comprising a non-magnetic material. In an embodiment, for example, the relative magnetic permeability of the top 132 of the mask mounting bracket may be about 1.

[0156] The mask mounting bracket 130 may include mask mounting bracket electrodes 133. The mask mounting bracket electrodes 133 may include or be formed of a conductive material.

[0157] At least a portion of the mask mounting bracket body 131 may include or be formed of a dielectric material. In an embodiment, for example, at least a portion of the mask mounting bracket body 131 may be in contact with the mask mounting bracket electrode 133 and may include or be formed of a dielectric material.

[0158] A potential can be applied to the mask mounting electrode 133. In an embodiment, for example, the potential of the mask mounting electrode 133 may be different from that of the mask strip 20 (see [link]). Figure 5 The electric potential of ).

[0159] In an implementation, for example, the mask mounting bracket electrode 133 and the mask strip 20 (see...) Figure 5 It can be connected to a power source. In an implementation, for example, the mask mounting electrode 133 and the mask strip 20 (see...) Figure 5 It can be connected to a DC voltage source.

[0160] Mask mounting bracket electrode 133 and mask strip 20 (see Figure 5 The mask can include more different charges. In an embodiment, for example, the mask mounting electrode 133 can include more positive charges, and the mask strip 20 (see...) Figure 5 The mask may include more negative charge. In an embodiment, for example, the mask mounting electrode 133 may include more negative charge, and the mask strip 20 (see [reference]) may include more negative charge. Figure 5 It can include more positive charges.

[0161] The top 132 of the mask mounting bracket can be located between the mask mounting bracket electrode 133 and the mask strip 20 (see...). Figure 5 Between the mask mounting electrode 133 and the mask strip 20. Coulomb force (or electrostatic force) can act between the mask mounting electrode 133 and the mask strip 20 (see...). Figure 5 Between. In other words, between the mask mounting bracket electrode 133 and the mask strip 20 (see...) Figure 5 They can be capacitively connected to each other.

[0162] In an implementation, for example, the attractive force can act on the mask mounting bracket electrode 133 and the mask strip 20 (see...). Figure 5 Between ), therefore, mask strip 20 (see Figure 5 It can make close contact with the top 132 of the mask mounting bracket.

[0163] Mask strip 20 (see Figure 5 The connection force between the mask mounting electrode 133 and the top 132 of the mask mounting bracket can depend on the potential of the mask mounting bracket electrode 133 and the mask strip 20 (see [reference]). Figure 5 The difference between the potentials of ( ).

[0164] In an implementation, for example, along with the mask mounting bracket electrode 133 and the mask strip 20 (see... Figure 5 The potential difference between the two increases, and the mask strip 20 (see Figure 5 The connection force between the top 132 of the mask mounting bracket and the top 132 can be increased.

[0165] After the welding of the mask strip 20 and the bridging strip 30 is completed, the mask strip 20 can be connected to the mask mounting part 100 (see...). Figure 5 ) separated, and bridging strip 30 (see Figure 5 It can be connected to the bridging mounting section 200 (see...) Figure 5 Separation.

[0166] refer to Figures 1 to 9 After the mask strip 20 and the bridging strip 30 are welded together, the intensity of the magnetic flux applied to the bridging strip 30 can be weakened or reduced.

[0167] In one embodiment, for example, after the welding of the mask strip 20 and the bridging strip 30 is completed, the bridging mount magnet 233 can be moved away from the top 232 of the bridging mount. In another embodiment, for example, the bridging mount magnet 233 can be moved downwards.

[0168] In some embodiments, for example, when the bridging mount magnet 233 includes an electromagnet, the magnitude of the current applied to the bridging mount magnet 233 can be reduced after the mask strip 20 and the bridging strip 30 are welded.

[0169] After the welding of the mask strip 20 and the bridging strip 30 is completed, the connection force between the mask mounting portion 100 and the mask strip 20 can be weakened. In an embodiment, for example, a reverse potential can be applied to the mask mounting electrode 133 and the mask strip 20. "Reverse potential" can refer to a potential that is opposite to the distribution of charge formed on the mask mounting electrode 133 and the mask strip 20, respectively.

[0170] Figure 10 This is a block diagram of a mask assembly apparatus according to an embodiment of the present disclosure.

[0171] refer to Figures 1 to 10 An embodiment of the mask assembly equipment 10 may include an input unit 310. The input unit 310 may receive input from the user, etc.

[0172] Input unit 310 can generate a first signal S1. The first signal S1 may include information about the input obtained by input unit 310. In an embodiment, for example, the first signal S1 may include information about at least one selected from the operation command of mask mounting part 100, the operation command of bridging mounting part 200, and the operation command of welding unit 350.

[0173] The mask assembly apparatus 10 may include a sensor unit 320. The sensor unit 320 may include, for example, a vision sensor.

In another embodiment, for example, sensor unit 320 may detect at least one selected from the position and orientation of bridging strip 30 relative to bridging mounting base 210.

[0175] In some embodiments, for example, sensor unit 320 may detect at least one selected from the position and intensity of the magnetic field of the bridging mount magnet 233. In some embodiments, for example, sensor unit 320 may detect the intensity of the current applied to the bridging mount magnet 233. In some embodiments, for example, sensor unit 320 may detect the magnitude of the potential applied to the mask mount electrode 133 and the mask strip 20.

[0176] The sensor unit 320 can generate a second signal S2. The second signal S2 may include information about the physical quantity detected by the sensor unit 320.

[0177] The mask assembly equipment 10 may include a control unit 330. The control unit 330 may be implemented by at least one selected from a computer, a processor, a server, and a circuit board.

[0178] The control unit 330 can perform operations. In one embodiment, for example, the control unit 330 can process signals. In another embodiment, for example, the control unit 330 can generate output signals S3, S4, and S5 based on input signals S1 and S2.

[0179] Input signals S1 and S2 may include at least one selected from the first signal S1 and the second signal S2. Output signals S3, S4 and S5 may include at least one selected from the third signal S3, the fourth signal S4 and the fifth signal S5.

[0180] The control unit 330 can transmit a third signal S3 to the mask mounting unit 100. The third signal S3 can include instruction information regarding the operation of the mask mounting unit 100. The mask mounting unit 100 can operate in response to the third signal S3.

[0181] In one embodiment, for example, the mask mounting leg 120 may operate in response to the third signal S3, and thus the position and orientation of the mask mounting bracket 130 may be adjusted. In another embodiment, for example, a potential may be formed in the mask mounting bracket electrode 133 in response to the third signal S3.

[0182] The control unit 330 can transmit a fourth signal S4 to the bridging mounting unit 200. The fourth signal S4 can include instruction information regarding the operation of the bridging mounting unit 200. The bridging mounting unit 200 can operate in response to the fourth signal S4.

[0183] In one implementation, for example, the bridging mounting leg 220 may operate in response to the fourth signal S4, and thus the position and orientation of the bridging mount 230 may be adjusted. In another implementation, for example, the position of the bridging mount magnet 233 may be adjusted in response to the fourth signal S4. In yet another implementation, for example, the current applied to the bridging mount magnet 233 may be adjusted in response to the fourth signal S4.

[0184] The control unit 330 can transmit a fifth signal S5 to the welding unit 350. The fifth signal S5 may include instruction information regarding the operation of the welding unit 350. The welding unit 350 can operate in response to the fifth signal S5. In one embodiment, for example, the welding unit 350 can operate in response to the fifth signal S5, and therefore the laser beam can radiate onto the mask strip 20.

[0186] refer to Figure 7 and Figure 11 In one embodiment, the bridging mounting portion 200 may be located above the mask mounting portion 100. For example, in another embodiment, the bridging mounting portion 200 may be located above the mask mounting bracket 130.

[0187] The bridging mounting leg 220 may be shaped to extend downward from the bridging mounting base 210. In an embodiment, for example, the upper end of the bridging mounting leg 220 may be connected to the bridging mounting base 210, and the lower end of the bridging mounting leg 220 may be connected to the bridging mounting bracket 230.

[0188] The bridging mount 230 may include a bridging mount top 232 that is coupled to the bridging mount leg 220. The bridging strip 30 may be attached to the lower surface of the bridging mount top 232. Hereinafter, the bridging mount top 232 may be referred to as the “bridging mount attachment portion”.

[0189] The bridging mount magnet 233 can be located on the top 232 of the bridging mount. The bridging mount magnet 233 can move toward or away from the top 232 of the bridging mount.

[0190] The bridging mounting part 200 and the mask mounting part 100 can be located on opposite sides relative to the mask strip 20. This can reduce the space constraints when installing the bridging mounting part 200.

[0192] refer to Figures 1 to 12 The mask assembly method (or method of assembling a mask) S10 may include a strip arrangement process S100. Strips 20 and 30 may include or indicate at least one selected from mask strip 20 and bridging strip 30.

[0193] In process S100, a mask strip 20 may be provided on the mask mounting bracket 130. In process S100, a bridging strip 30 may be provided on the bridging mounting section 200.

[0194] In one embodiment, for example, in process S100, the bridging strip 30 can be adsorbed onto the top 232 of the bridging mounting bracket. In another embodiment, for example, in process S100, the bridging strip 30 can be aligned.

[0195] In process S100, a clamp (not shown) connected to the mask mounting base 110 can fix the mask strip 20 to the mask mounting frame 130.

[0196] In some embodiments, for example, in process S100, a Coulomb force may act between the mask strip 20 and the mask mounting electrode 133. In some embodiments, for example, in process S100, the mask strip 20 may be in close contact with the top 132 of the mask mounting bracket.

In process S400, the bridging mounting bracket 230 may be returned to its original or initial position. In an embodiment, for example, in process S400, the bridging mounting bracket 230 may be close to the bridging mounting base 210.

[0202] In process S400, the connection between the mask strip 20 and the mask mounting part 100 can be released. In process S400, the connection between the fixture (not shown) and the mask strip 20 can be released.
