Description

Technical Field

[0001] This invention relates to a panel splicing technology, and more particularly to a panel splicing equipment and a method for manufacturing a splicing display device. Background Technology

[0002] One type of splicing display device uses rubber suction cups to pick up and place display panels, and then splices these panels on a large-size platform. During this process, the flatness of the platform, the warpage of the panels, and the flatness of the rubber suction cups all affect the alignment accuracy of the display panels on the platform. If the positional offset of the display panel on the platform exceeds the allowable limit, the display panel must be retrieved using the rubber suction cups, re-aligned, and then placed back on the platform. However, during the re-placement process, the aforementioned influencing factors can still cause unpredictable positional offsets in the display panel. Therefore, the process of retrieval, re-alignment, and placement is often repeated multiple times to achieve an acceptable offset tolerance, which is not only time-consuming but also has a low success rate. Summary of the Invention

[0003] This invention provides a panel splicing device with better splicing efficiency.

[0004] This invention provides a method for manufacturing a splicing display device, which offers greater flexibility and efficiency in panel alignment during splicing.

[0005] The panel splicing device of the present invention includes a base platform, a pick-and-place mechanism, a plurality of first image capturing elements, and a splicing stage. The pick-and-place mechanism and the plurality of first image capturing elements are movably mounted on the base platform. The splicing stage is mounted on the base platform and includes a plurality of alignment mechanisms and a plurality of carriers. These carriers are respectively mounted on the alignment mechanisms and each has a receiving surface facing the pick-and-place mechanism. Each alignment mechanism is adapted to drive a corresponding one of the carriers to move or rotate along at least two directions parallel to the receiving surface.

[0006] The manufacturing method of the splicing display device of the present invention is applicable to the panel splicing equipment as described above, and includes: having a pick-and-place mechanism extract a display panel and move it to a position on a base platform where a splicing stage is provided; using multiple first image capturing elements to perform a feature alignment of the display panel on the pick-and-place mechanism; having the pick-and-place mechanism place the display panel on a first platform of multiple platforms of the splicing stage; performing a specification detection on the position of the display panel on the splicing stage; using multiple first image capturing elements and a first alignment mechanism of multiple alignment mechanisms to perform another feature alignment of the display panel on the first platform; and performing another specification detection on the position of the display panel on the splicing stage. The first platform is disposed on the first alignment mechanism.

[0007] Based on the above, in a method for manufacturing a splicing display device according to an embodiment of the present invention, the splicing platform of the panel splicing equipment is divided into multiple platforms, and each platform is provided with an alignment mechanism. After the display panel is placed onto one of the platforms by the pick-and-place mechanism, if the positional offset of the display panel on the splicing platform fails to pass the specification test, the alignment mechanism can directly perform another feature alignment on the display panel on the platform. This not only eliminates the lengthy process of the pick-and-place mechanism extracting the display panel again, but also significantly increases the alignment accuracy of the display panel in the second feature alignment. That is, it can simultaneously improve the splicing efficiency and accuracy of the display panels. Attached Figure Description

[0035] As used herein, “about,” “approximately,” “essentially,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or, for example, within ±30%, ±20%, ±15%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” “essentially,” or “substantially” herein may be chosen to select a more acceptable range of deviations or standard deviations depending on the nature of the measurement, the cutting nature, or other properties, and a single standard deviation may not be applicable to all properties.

[0036] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it may be directly on or connected to the other element, or intermediate elements may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, no intermediate elements are present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, an "electrical connection" may involve the presence of other elements between two elements.

[0037] 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 illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being "below" to another element will be oriented "above" to that element. Thus, the exemplary term "below" can include both "below" and "above" orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being "below" or "under" another element will be oriented "above" to that element. Thus, the exemplary terms "above" or "below" can include both "above" and "below" orientations.

[0038] This document describes exemplary embodiments with reference to cross-sectional views as schematic diagrams of idealized embodiments. Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0041] Please refer to Figure 2A , Figure 2E and Figure 2F The panel splicing device 1 includes a base platform 100, a first moving mechanism 110, a film picking and placing mechanism 200, multiple first image capturing elements, and a splicing stage 250. The first moving mechanism 110 is movably mounted on the base platform 100. The film picking and placing mechanism 200 and the first image capturing elements are mounted on the first moving mechanism 110. For example, in this embodiment, the number of first image capturing elements can be three, namely first image capturing element 210a, first image capturing element 210b, and first image capturing element 210c, and these first image capturing elements 210a to 210c respectively correspond to multiple alignment features on the display panel DP. In order to meet different alignment requirements or panel designs, the number and position of the first image capturing elements can be adjusted, and the present invention does not impose any limitations.

[0042] In this embodiment, the first moving mechanism 110 is adapted to drive the film pick-and-place mechanism 200 and the first image capturing element to move along three mutually perpendicular moving axes, such as moving axis MA1, moving axis MA2, and moving axis MA3. In one embodiment, the film pick-and-place mechanism 200 may be a robotic arm equipped with multiple rubber suction cups, but is not limited thereto.

[0043] The splicing stage 250 is mounted on the base platform 100 and includes a base BS, multiple stages CS, and multiple alignment mechanisms ALM. For example, in this embodiment, the splicing stage 250 may be selectively mounted on a moving mechanism 130 on the base platform 100, and the moving mechanism 130 is adapted to drive the splicing stage 250 along at least one direction (e.g., Figure 2A The device can be moved vertically to display the completed splicing display unit, but is not limited to this.

[0044] Multiple alignment mechanisms (ALMs) are fixed on the base BS, and multiple platforms (CSs) are respectively disposed on these alignment mechanisms (ALMs). In this embodiment, the platforms (CSs or alignment mechanisms (ALMs) of the splicing stage 250 are arranged in a 2x3 array, for example. That is, the number of platforms (CSs) and alignment mechanisms (ALMs) is six each, namely the first platform (CS1) to the sixth platform (CS6) and the first alignment mechanism (ALM1) to the sixth alignment mechanism (ALM6). However, the present invention is not limited to this. In other embodiments not shown, the number and arrangement of the platforms of the splicing stage can be adjusted to a 2x2, 4x4, 5x5, 6x6, or 8x8 array according to the size of the splicing display device.

[0045] Specifically, each of the multiple platforms CS has a receiving surface CSrs facing the pick-and-place mechanism 200, and each alignment mechanism ALM is adapted to move or rotate one of these platforms CS (i.e., the platform CS connected to or overlapping with it) along at least two directions parallel to the receiving surface CSrs. For example, in this embodiment, the alignment mechanism ALM is adapted to move the platform CS it carries along a first moving axis MA1” and a second moving axis MA2”, and rotate about a rotation axis RA perpendicular to the receiving surface CSrs of the platform CS, wherein the axial direction of the first moving axis MA1” is perpendicular to or intersects the axial direction of the second moving axis MA2”.

[0046] like Figure 5A As shown in detail, the alignment mechanism ALM may include two first slide rail mechanisms 251a and 251b and two second slide rail mechanisms 252a and 252b, wherein each slide rail mechanism may be a combination of a slider and a slide rail, and the slider is adapted to slide along a specific direction in the slide rail, but is not limited thereto. For example, in this embodiment, the two second slide rail mechanisms 252a and 252b may be disposed on the sliders of the two first slide rail mechanisms 251a and 251b, and move along a first direction D1 or its reverse direction under the drive of the first slide rail mechanisms. The stage CS is disposed on the sliders of the two second slide rail mechanisms 252a and 252b, and moves along a second direction D2 or its reverse direction under the drive of the second slide rail mechanisms. Here, the first direction D1 and the second direction D2 are, for example, parallel to the... Figure 2F The first moving axis MA1” and the second moving axis MA2” are in two directions.

[0047] It is particularly noteworthy that, in this embodiment, the actuation of the second slide rail mechanism 252a and the second slide rail mechanism 252b of the alignment mechanism ALM can also operate synchronously and in reverse. For example, as Figure 5BAs shown, the slider of the second slide rail mechanism 252b moves along the second direction D2, while the slider of the other second slide rail mechanism 252a moves in the opposite direction of the second direction D2 (i.e., direction D2R). In this way, the stage CS can be driven to rotate clockwise about the axis RA, and conversely, the stage CS can be driven to rotate counterclockwise about the axis RA (not shown).

[0048] Please refer to this again. Figure 2A In this embodiment, the panel splicing device 1 may also optionally include a detection module 220 and a feeding platform 230. The feeding platform 230 is movably mounted on the base platform 100 and is suitable for carrying the display panel DP. The detection module 220 is mounted on the moving path of the feeding platform 230 and is provided with multiple second image capturing elements.

[0049] For example, the feed table 230 can be fixed to a second moving mechanism 120 on the base platform 100, and the second moving mechanism 120 is adapted to drive the feed table 230 along at least one direction (e.g., Figure 2A The axial movement of the central moving axis MA4 causes the feeding stage 230 to move to or away from the position or area where the detection module 220 is located on the base platform 100, but this is not a limitation. In this embodiment, the detection module 220 may include four second image capturing elements 220a to 220d, and these four second image capturing elements 220a to 220d are respectively arranged at the four corners of the display panel DP. That is, when the feeding stage 230 is positioned in the area where the detection module 220 is set, the four corners of the display panel DP it carries will be located within the image capturing range of these four second image capturing elements 220a to 220d respectively.

[0050] The following will provide an exemplary description of the manufacturing method of the splicing display device applicable to the above-mentioned panel splicing equipment 1.

[0051] Please refer to Figure 1 and 2A First, the display panel DP is placed on the feeding platform 230 (i.e., step S01), and the alignment features of the display panel DP on the feeding platform 230 are confirmed using the detection module 220 (i.e., step S03). In this embodiment, the alignment features of the display panel DP are, for example, four alignment marks respectively set at the four corners of the display panel DP, such as: alignment mark AM1-2, alignment mark AM2-2, alignment mark AM3-2 and alignment mark AM4-2 (e.g., ...). Figure 3 (As shown).

[0052] For example, during the process of the detection module 220 confirming the display panel DP on the feed station 230, the four second image capturing elements 220a to 220d will capture images of the aforementioned four corners of the display panel DP. The detection module 220 will determine whether the four alignment marks of the display panel DP conform to the specifications based on the four images captured by the four second image capturing elements 220a to 220d, namely images IM1 to IM4, such as whether the alignment marks are clearly visible or whether their setting position is correct.

[0053] When an abnormal alignment feature is detected in the inspected display panel DP, it will be replaced. That is, another display panel DP will be placed on the feed stage 230 and its alignment feature will be checked again.

[0054] In this embodiment, the placement of the display panel DP and the confirmation of its alignment features are performed in different areas on the base platform 100 by the feeding stage 230. Please refer to... Figures 2A to 2C Therefore, before confirming the alignment features of the display panel DP, the feed station 230 needs to be moved to the position or area of ​​the base platform 100 where the detection module 220 is located (i.e., step S02). After confirming the alignment features of the display panel DP, the feed station 230 needs to be moved away from the position or area of ​​the base platform 100 where the detection module 220 is located (i.e., step S04).

[0055] Regardless of the confirmation result of the alignment features of the display panel DP, the display panel DP that has completed the inspection needs to leave the setting area of ​​the inspection module 220, for example, by being transferred back to the initial position of the feeding station 230 when it was fed to wait for the replacement (if an abnormality is confirmed) or by being picked up by the pick-and-place mechanism 200 (if normality is confirmed).

[0056] However, the present invention is not limited thereto. In other embodiments, the feeding platform 230 may also be fixed on the base platform 100, while the detection module 220 may be movably disposed on the base platform 100. When the display panel DP of the feeding platform 230 needs to be confirmed for alignment features, the detection module 220 may move above the feeding platform 230 to detect the display panel DP, and after the detection is completed, it may move out of the position of the feeding platform 230. That is, the present invention does not limit the actuation relationship between the feeding platform 230 and the detection module 220.

[0057] Please refer to Figure 1 , Figure 2C and Figure 2D After the alignment features of the display panel DP on the feeding platform 230 are confirmed to be without abnormalities, the pick-and-place mechanism 200 is moved to the feeding platform 230 to pick up the display panel DP on the feeding platform 230, and then moved to the position where the splicing platform 250 is provided on the base platform 100 (i.e. step S05).

[0058] For example, Figure 2A The display panel DP placed on the feeding stage 230 is the second display panel DP (i.e., display panel DP2) to be spliced ​​in the splicing manufacturing process of the splicing display device. Therefore, the pick-and-place mechanism 200, which has completed the extraction of display panel DP2, can be moved above the stage CS2 of the splicing stage 250. Next, multiple first image capturing elements 210a to 210c are used to perform a feature alignment on the display panel DP2 on the pick-and-place mechanism 200 (i.e., step S06). After the feature alignment is completed, the pick-and-place mechanism 200 places the display panel DP2 on the stage CS2 (i.e., the first stage) of the splicing stage 250 along the axial direction of the moving axis MA3 (i.e., step S07, as shown in step S07). Figure 2E (As shown).

[0059] After the display panel DP2 is placed on the stage CS2 of the splicing table 250, the position of the display panel DP2 on the splicing table 250 is checked for accuracy (i.e., step S08). The accuracy check step may include confirming whether the offset of the alignment features of the display panel DP2 exceeds the allowable value. For example, during the accuracy check, the three images IM1a, IM2a, and IM3a captured by the three first image capturing elements 210a, 210b, and 210c located at the three corners of the display panel DP2 show that the position of the display panel DP2 has shifted after being placed on the stage CS2 (e.g., ...). Figure 4A (as shown in the figure), for example, deviating from the position shown by the dotted line in the figure.

[0060] It should be noted that the positional offset of display panel DP2 on the splicing table 250 can be determined by the distance between the alignment mark of display panel DP2 and the alignment mark of the previously placed display panel DP1. For example... Figure 4A As shown, for example, when the distance between the alignment mark AM1-2 at the upper left corner of display panel DP2 and the alignment mark AM3-1 at the upper right corner of display panel DP1, or / and the distance between the alignment mark AM2-2 at the lower left corner of display panel DP2 and the alignment mark AM4-1 at the lower right corner of display panel DP1, exceeds the predetermined range, the system determines that the offset of display panel DP2 on the splicing table 250 exceeds the allowable value.

[0061] It should be understood that if the previously placed display panel DP1 is located below display panel DP2, the positional offset of display panel DP2 on the video wall 250 can be determined by the distance between the alignment mark AM4-2 at the lower right corner of display panel DP2 and the alignment mark AM3-1 at the upper right corner of display panel DP1, or / and the distance between the alignment mark AM2-2 at the lower left corner of display panel DP2 and the alignment mark (not shown) at the upper left corner of display panel DP1.

[0062] Please continue to refer to Figure 1 and Figure 2F After the position of display panel DP2 on the splicing stage 250 is checked for compliance, if the result meets the specifications, the splicing step of display panel DP2 on the splicing stage 250 is completed. Conversely, if the result does not meet the specifications (i.e., the offset of the alignment feature of display panel DP2 exceeds the allowable value), multiple first image capturing elements 210a to 210c and the alignment mechanism ALM are used to perform another feature alignment of display panel DP2 on stage CS2 (i.e., step S09).

[0063] In detail, in another feature alignment, the alignment mechanism ALM2 (i.e., the first alignment mechanism, such as the receiving platform CS2 (i.e., the first platform) is made to receive the platform CS2 (i.e., the first platform). Figure 2E (As shown) The display panel DP2 on the stage CS2 is moved along at least two directions (e.g., the axial direction of the first moving axis MA1” and the axial direction of the second moving axis MA2”) or rotated along the axis RA perpendicular to the bearing surface CSrs of the stage CS. That is, another feature alignment of the display panel DP2 is performed by the alignment mechanism ALM2 of the splicing stage 250, instead of the traditional method of using the pick-and-place mechanism 200 to retrieve the display panel DP2 again and re-align it. This not only eliminates the lengthy process of the pick-and-place mechanism 200 retrieving the display panel DP2, but also avoids unpredictable positional shifts when the display panel DP2 is transferred from the pick-and-place mechanism 200 to the stage CS2. Therefore, the alignment accuracy of the display panel DP2 in the second feature alignment can be significantly increased, and the splicing efficiency of the display panel DP2 can be effectively improved.

[0064] For example, in this embodiment, in order to correct such Figure 4A The offset shown by the three images IM1a, IM2a, and IM3a indicates that the alignment mechanism ALM2 can drive the display panel DP2 to rotate clockwise along the pivot RA and move to the left along the first moving axis MA1".

[0065] After completing another feature alignment, the position of display panel DP2 on the splicing stage 250 is checked again to meet specifications (i.e., step S08 is repeated). For example, if during the other specification check, the three images IM1b, IM2b, and IM3b captured by the three first image capturing elements 210a, 210b, and 210c respectively show that the position of display panel DP2 on the splicing stage 250 has been corrected to meet specifications after the movement and adjustment of the alignment mechanism ALM2 (e.g., ...). Figure 4B As shown), the splicing step of display panel DP2 on splicing stage 250 is then completed. Conversely, if the other specification test result is still non-compliant, step S09 needs to be repeated, that is, the display panel DP2 on stage CS2 is re-aligned using multiple first image capturing elements 210a, 210b, 210c and alignment mechanism ALM2, until the position of display panel DP2 on splicing stage 250 meets the specifications.

[0066] Since the third display panel DP to the sixth display panel DP can be achieved by repeating the above process... Figures 2A to 2F The splicing process is completed by each of the following steps on the stage CS3, stage CS4, stage CS5 and stage CS6 of the splicing stage 250. For detailed instructions, please refer to the relevant paragraphs above, and they will not be repeated here.

[0067] In summary, in the manufacturing method of the splicing display device according to an embodiment of the present invention, the splicing platform of the panel splicing equipment is divided into multiple platforms, and each platform is equipped with an alignment mechanism. After the display panel is placed onto one of the platforms by the pick-and-place mechanism, if the positional offset of the display panel on the splicing platform fails to pass the specification test, the alignment mechanism can directly perform another feature alignment on the display panel on the platform. This not only eliminates the lengthy process of the pick-and-place mechanism extracting the display panel again, but also significantly increases the alignment accuracy of the display panel in the second feature alignment. That is, it can simultaneously improve the splicing efficiency and accuracy of the display panels.
