Description

Technical Field

[0001] This disclosure relates to a laser device, and more specifically, to a laser device used in a cutting process. Background Technology

[0002] Laser beams can be used in the manufacturing process of display devices. Laser beams are high-density heat sources and can be used for marking, cutting, welding, or heat treatment. Laser processing is non-contact, causes less wear, and allows for the precision machining of various desired properties.

[0003] The laser device may include a laser source that emits a laser beam, a scanner that controls the radiation position of the laser beam emitted from the laser source, and a lens module that focuses the laser beam whose radiation position has been controlled.

[0004] In laser devices where the lens module is cantilevered to the frame, the processing position may be distorted due to vibration, and marking, cutting, welding, or heat treatment may be performed in undesirable positions. Therefore, the processing quality of the object being processed (e.g., the display quality of a display device) may be degraded. Utility Model Content

[0037] The present invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are illustrated. However, the present 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 present invention to those skilled in the art. The same reference numerals refer to the same elements throughout.

[0038] It should be understood that when an element is said to be "on" another element, it may be directly on the other element, or there may be an intermediary element between them. Conversely, when an element is said to be "directly" on another element, there is no intermediary element.

[0039] It will be understood that although the terms “first,” “second,” and “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or sections, these elements, components, areas, layers, and / or sections should not be limited by these terms. These terms are used only to distinguish one element, component, area, layer, or section from another. Therefore, without departing from the teachings herein, the “first element,” “component,” “area,” “layer,” or “section” discussed below may be referred to as a second element, component, area, layer, or section.

[0040] 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 the singular and the plural 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, unless the context clearly indicates otherwise, “a element” has the same meaning as “at least one element.” “At least one” should not be construed as limiting “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 “comprises / comprising” and / or “includes / including” as used in this specification indicate the presence of a described feature, area, integer, step, operation, element, and / or component, but do not exclude the presence or addition of one or more other features, areas, integers, steps, operations, elements, components, and / or groups thereof.

[0041] 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 illustrated in the figures. It will be understood that, in addition to the orientations depicted in the figures, relative terms are intended to encompass different orientations of the device. 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, the term “below” can encompass both “below” and “above” orientations, depending on the specific orientation of the figure. 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.

[0042] Unless otherwise specified, 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 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.

[0043] Embodiments are described herein with reference to cross-sectional views that are schematic illustrations of idealized embodiments. Therefore, variations in shape as illustrated are to be expected due to factors such as 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 should include shape deviations, for example, due to manufacturing processes. For instance, 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 are schematic in nature, and their shapes are not intended to illustrate precise shapes of areas, nor are they intended to limit the scope of the claims.

[0044] Figure 1 This is a perspective view of a laser device according to an embodiment of the present disclosure.

[0045] refer to Figure 1 According to an embodiment of the present disclosure, a laser device 1 may include a laser source 100, a scanner 200, a lens module 300, and a lens adapter 400.

[0046] In one embodiment, laser source 100 can generate a laser beam LB and emit the laser beam LB to scanner 200. In one embodiment, for example, laser source 100 can emit a single beam, or laser source 100 can emit multiple beams. In one embodiment, for example, the wavelength, amplitude, or energy density of the laser beam LB can be controlled according to the process.

[0047] In one embodiment, the scanner 200 may be located in the path of the laser beam LB emitted from the laser source 100. In one embodiment, for example, the laser beam LB emitted from the laser source 100 may enter the scanner 200 in a straight line.

[0048] In one embodiment, the scanner 200 can control the path of the laser beam LB. In one embodiment, for example, the direction of travel of the laser beam LB incident on the scanner 200 can be changed toward the lens module 300. In such an embodiment, the scanner 200 may include at least one mirror to change the direction of travel of the laser beam LB incident on the scanner 200. In one embodiment, for example, the scanner 200 may be a galvanometer including two mirrors. However, this disclosure is not limited thereto.

[0049] In one embodiment, the lens module 300 may be located in the path of the laser beam LB, the path of which is controlled by the scanner 200, and the lens module 300 may converge the laser beam LB. In one embodiment, for example, the laser beam LB emitted from the scanner 200 may be incident on the lens module 300, and the laser beam converged by the lens module 300 may illuminate the object OB to be processed on the stage STA.

[0050] In one embodiment, for example, the object to be processed OB may be a substrate. In one embodiment, for example, in the case of a display device manufacturing process, the object to be processed OB may be a substrate comprising glass. In another embodiment, for example, the object to be processed OB may be a substrate comprising plastic. However, this disclosure is not limited thereto.

[0051] In one embodiment, for example, the lens module 300 may be an F-theta lens unit. An F-theta lens unit can form a focal point on the same plane, independent of the incident angle of the laser beam LB. Therefore, in embodiments where the laser device includes an F-theta lens unit, laser processing can be performed with the same energy regardless of the position of the laser beam LB illuminating the object OB to be processed. In one embodiment, for example, the laser processing may be a cutting process. However, this disclosure is not limited thereto.

[0052] In one embodiment, for example, the lens module 300 may include a housing and at least one lens housed within the housing. Reference will be made later. Figure 5 , Figure 6 and Figure 7 This describes the detailed structure of the lens module 300.

[0053] In one embodiment, the lens adapter 400 may include a first adapter 410 and a second adapter 420. In one embodiment, the lens adapter 400 may connect the lens module 300 to the scanner 200. In such an embodiment, the lens module 300 may be located between the first adapter 410 and the second adapter 420.

[0054] The above reference Figure 1 The laser device 1 described is illustrative, and this disclosure is not limited thereto. In one embodiment, for example, the laser device 1 may further include various components for laser processing.

[0055] In one embodiment, for example, the laser device 1 may further include a path switching member disposed between the laser source 100 and the scanner 200. This path switching member can change the path of the laser beam LB emitted from the laser source 100.

[0056] Figure 2 for Figure 1 A top view of the laser device. Figure 3 and Figure 4 For example, including Figure 1 A view of the lens adapter in a laser device.

[0057] refer to Figure 2 , Figure 3 and Figure 4In one embodiment, the first adapter 410 is movable along the first axis AX1 in the first direction DR1, and the second adapter 420 is movable along the second axis AX2 in the first direction DR1.

[0058] In one embodiment, for example, the first axis AX1 may be located in the first adapter 410, and the second axis AX2 may be located in the second adapter 420. In one embodiment, for example, the first axis AX1 and the second axis AX2 may extend in a first direction DR1.

[0059] In one embodiment, for example, the first adapter 410 is movable along a first axis AX1 in a direction opposite to the direction of gravity, and the second adapter 420 is movable along a second axis AX2 in the direction of gravity. In such an embodiment, the gap between the first adapter 410 and the second adapter 420 (e.g., Figure 15 The first separation distance (SD) can be greater after the movement than before the movement.

[0060] In one embodiment, the first adapter 410 is movable along a first axis AX1 in the direction of gravity, and the second adapter 420 is movable along a second axis AX2 in the direction opposite to the direction of gravity. In such an embodiment, the gap between the first adapter 410 and the second adapter 420 (e.g., Figure 16 The second separation distance SD') can be smaller after the movement than before the movement.

[0061] In one embodiment, scanner 200 may be connected to first adapter 410, and when first adapter 410 moves in the first direction DR1, only scanner 200 may move in the first direction DR1. Lens module 300 may be connected to second adapter 420, and when second adapter 420 moves in the first direction DR1, only lens module 300 may move in the first direction DR1.

[0062] Because the laser device 1 includes a gap controllable (e.g., Figure 15 First separation distance SD or Figure 16 The first adapter 410 and the second adapter 420 of the second separation distance SD') allow for easy installation (or replacement, etc.) of the scanner 200 and / or lens module (e.g., Figure 1 Lens module 300).

[0063] In one embodiment, such as Figure 2 As shown, the laser device 1 may further include an interval control member 500 connected to a first axis AX1. The interval control member 500 can move the first adapter 410 in a first direction DR1 based on at least one of its operating directions.

[0064] In one embodiment, for example, the interval control member 500 may be a micro-motion dial. In such an embodiment, when the micro-motion dial rotates in one direction, the first adapter 410 may move in the direction opposite to the direction of gravity. In such an embodiment, when the micro-motion dial rotates in the direction opposite to one direction, the first adapter 410 may move in the direction of gravity.

[0065] In one embodiment, the laser device 1 may further include a linear moving member 600 mounted on the second adapter 420 in a direction parallel to the second axis AX2 and a driving member 700 connected to the second axis AX2. In one embodiment, for example, the linear moving member 600 may extend along a first direction DR1. The driving member 700 may move the second adapter 420 along the linear moving member 600 in the first direction DR1.

[0066] In one embodiment, for example, the linear motion member 600 may be an LM guide, and the drive member 700 may be a motor. In such an embodiment, when the motor rotates in one direction, the second adapter 420 may move in the direction of gravity. In such an embodiment, when the motor rotates in the opposite direction, the second adapter 420 may move in the direction opposite to gravity. However, this disclosure is not limited thereto. The types of the linear motion member 600 and the drive member 700 can be varied in various ways.

[0067] Therefore, the gap between the first adapter 410 and the second adapter 420 included in the laser device 1 can be controlled. However, this disclosure is not limited thereto. In one embodiment, for example, the first adapter 410 may be operated automatically, and the second adapter 420 may be operated manually.

[0068] In one embodiment, such as Figure 3 As shown, the laser device 1 may further include a support member 800 disposed on the second adapter 420. The support member 800 supports the central portion of the lens module 300 rather than the edge portion of the lens module 300. Therefore, the lens module 300 can be supported more stably. (See later...) Figure 5 , Figure 6 and Figure 7 Describe the detailed features of the lens module 300 and the support member 800.

[0069] In one embodiment, the laser device 1 may further include a stop 900 disposed on one side of the support member 800. The stop 900 may restrict (e.g., stop or block) movement of the lens module 300 in the second direction DR2. In one embodiment, for example, when the lens module 300 is mounted between the first adapter 410 and the second adapter 420, the stop 900 may be located near the end of the path along which the lens module 300 moves.

[0070] refer to Figure 2 , Figure 3 and Figure 4 The lens adapter 400 included in the laser device 1 described above is illustrative, and this disclosure is not limited thereto. For example, the laser device 1 may further include various components required for laser processing, or some components may be omitted.

[0071] In one embodiment, for example, such as Figure 2 As shown, the second adapter 420 may have a double-forked shape (similar to) including a first facet, a second facet, and a third facet that intersect each other. The shape of the lens adapter 400 can be varied in various ways, and the linear moving member 600 can be mounted on the second and / or third surface instead of the first surface, or the linear moving member 600 can be mounted on all three surfaces (the first, second, and third surfaces).

[0072] In one embodiment, such as Figure 3 As shown, the support member 800 may have a shape that can accommodate the lens module 300 by cutting a semi-circular shape into a rectangular plate, and the stop 900 has a triangular shape; however, this disclosure is not limited thereto. The shapes of the support member 800 and the stop 900 can be changed in various ways. Furthermore, the dimensions or positions of the support member 800 and the stop 900 can be changed in various ways.

[0073] Figure 5 , Figure 6 and Figure 7 To include Figure 1 A view of the lens module in a laser device. Figure 8 For the purpose of explanation including Figure 1 A plan view of the second fastening component in the laser device.

[0074] refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 For example, one embodiment of the lens module 300 may include a housing and at least one lens housed within the housing.

[0076] In one embodiment, for example, the first lens portion 310, the second lens portion 320, and the connecting portion 330 may be formed separately and then assembled. However, this disclosure is not limited thereto. In one embodiment, for example, the first lens portion 310 and the connecting portion 330 may be integrally formed into a single, inseparable part, and then the second lens portion 320 may be connected to the connecting portion 330.

[0077] In one embodiment, the first lens portion 310 may accommodate a first lens 312, and the second lens portion 320 may accommodate a second lens 322. The connecting portion 330 may have a longest diameter that is larger than the longest diameter of the first lens portion 310 and the longest diameter of the second lens portion 320.

[0078] In one embodiment, a plurality of first holes HO1 and a plurality of second holes HO2 may be defined in the connecting portion 330. The plurality of second holes HO2 may be spaced apart from the plurality of first holes HO1. Each of the plurality of first holes HO1 and the plurality of second holes HO2 may be parallel to a laser beam incident on the lens module 300 (e.g., Figure 1 The path of the laser beam (LB) is formed.

[0079] In one embodiment, the laser device 1 may further include a first connector BO1, which is fastened to each of a plurality of first holes HO1 and includes an annular portion. In one embodiment, for example, the first connector BO1 may be an eye bolt. However, this disclosure is not limited thereto. In embodiments, the type of the first connector BO1 can be varied in various ways.

[0080] In one embodiment, the laser device 1 may further include a second connector BO2, which is fastened to each of a plurality of second holes HO2 and controls the flatness of the lens module 300. In one embodiment, for example, the second connector BO2 may be a height-adjustable screw. However, this disclosure is not limited thereto. In one embodiment, the type of the second connector BO2 may be varied in various ways.

[0081] like Figure 1 , Figure 3 and Figure 6 As shown, in one embodiment, the connection portion 330 of the lens module 300 may be mounted on the support member 800. In one embodiment, for example, the scanner 200 may be coupled to a first adapter 410, and the lens module 300 may be coupled to a second adapter 420.

[0082] refer to Figure 6 and Figure 7 The lens module 300 may include an aperture ST, a first lens 312, a second lens 322, and a window 324. The aperture ST, the first lens 312, the second lens 322, and the window 324 may be arranged sequentially along the travel direction of the laser beam LB incident on the lens module 300.

[0083] In the following text, for ease of description, the scanner (e.g., Figure 1 The side adjacent to the scanner 200 and where the laser beam LB is incident on the lens module 300 is referred to as the first side S01, and the side adjacent to the object to be processed OB and where the laser beam LB is emitted from the lens module 300 is referred to as the second side S02. In one embodiment, for example, in the direction from the first side S01 to the second side S02, the aperture ST, the first lens 312, the second lens 322, and the window 324 are arranged sequentially.

[0084] The aperture ST can be set to be adjacent to the scanner. The diameter of the aperture ST can be designed in various ways according to the amount of light to be transmitted.

[0085] In one embodiment, the first lens 312 and the second lens 322 may have a convex shape in the direction of travel of the laser beam LB. In one embodiment, for example, the first lens 312 and the second lens 322 may have a meniscus shape with a concave surface in the first side S01, or the first lens 312 and the second lens 322 may be spherical on two surfaces opposite to the direction of travel of the laser beam LB. However, this disclosure is not limited thereto. In another embodiment, one of the two surfaces of the first lens 312 and the second lens 322 facing the direction of movement of the laser beam LB may be spherical, and the other surface facing that one surface may be non-spherical. In one embodiment, for example, one surface adjacent to the first side S01 may be a spherical surface, and the other surface adjacent to the second side S02 may be a non-spherical surface. In one embodiment, for example, one surface adjacent to the first side S01 may be non-spherical, and the other surface adjacent to the second side S02 may be spherical.

[0086] In one embodiment, each of the first lens 312 and the second lens 322 may include a material with high light transmittance. In one embodiment, for example, each of the first lens 312 and the second lens 322 may include zinc selenide (ZnSe) or germanium (Ge). These may be used individually or in combination with each other. In one embodiment, for example, the first lens 312 may include zinc selenide, and the second lens 322 may include germanium. In one embodiment, for example, the first lens 312 may include germanium, and the second lens 322 may include zinc selenide. However, this disclosure is not limited thereto.

[0103] As described above, in one embodiment, the first connector BO1 may include an annular portion. In one embodiment, for example, the first connector BO1 may be a bolt with an eye.

[0104] Cable W can be captured by the loop of the first connector BO1. Lens module 300 can be lifted while cable W is captured by the loop.

[0105] In one embodiment, for example, the mobile stage MS can slide along the second direction DR2. The lens module 300 can be mounted on the mobile stage MS.

As described above, Figure 13 The second separation distance SD' can be less than Figure 12 The first separation distance SD.

[0113] The height of the first adapter 410 can be readjusted so that the lens module 300 can be adjacent to the first adapter 410. As described above, the height of the first adapter 410 can be controlled using the spacing control member 500.

[0114] In one embodiment, for example, an adapter may be additionally disposed between the lens module 300 and the first adapter 410. In one embodiment, as... Figure 5 As shown, an additional adapter 400', including a third adapter 430 and a fourth adapter 440, may be further disposed between the scanner 200 and the lens module 300.

[0115] refer to Figure 5 and Figure 13 For example, along the laser beam (e.g., Figure 1 The scanner 200, first adapter 410, third adapter 430, fourth adapter 440, and lens module 300 may be arranged sequentially along the path of the laser beam (LB). However, this disclosure is not limited thereto. In one embodiment, for example, the additional adapters may be omitted or may have a different form.

[0116] After controlling the second separation distance SD' (S240), the flatness of the lens module 300 can be controlled (S250). In one embodiment, the second connector BO2 can be used to control the flatness.

[0117] After controlling the flatness of the lens module 300 (S250), the lens module 300 can be secured to each of the first adapter 410 and the second adapter 420 (S260). In one embodiment, the lens module 300 can be secured via a third connector BO3.

[0118] In one embodiment, the first connector BO1 of the movable lens module 300, the second connector BO2 that controls the flatness of the lens module 300, and the third connector BO3 that fixes the lens module 300 can be positioned symmetrically. However, this disclosure is not limited thereto.

The lens module 300 may be connected to the second adapter 420, and when the second adapter 420 moves in the first direction DR1, only the lens module 300 may move in the first direction DR1.

[0122] Therefore, when the scanner 200 is replaced, only the scanner 200 can be replaced by separating the scanner 200 from the first adapter 410 while the lens module 300 is fastened to the second adapter 420.

[0123] In addition, each of the first adapter 410 and the second adapter 420 is movable in the first direction DR1.

[0124] Therefore, when the gap between the first adapter 410 and the second adapter 420 is made to have a first separation distance SD by moving the first adapter 410 in the direction opposite to the direction of gravity and moving the second adapter 420 in the direction of gravity, only the lens module 300 can be separated and replaced while the scanner 200 is fastened to the first adapter 410.

[0125] In one embodiment, as described above, when the lens module 300 is replaced, the first adapter 410 and the second adapter 420 can move together, and the separation distance (e.g., a first separation distance SD or a second separation distance SD') can be controlled. However, this disclosure is not limited thereto. In one embodiment, for example, the separation distance can be controlled by moving only the first adapter 410 or only the second adapter 420.
