[0084] The alignment measurement unit (AMU) can accurately photograph or measure the alignment status between the upper material UMT and the lower material DMT using the above-described configuration.

[0085] Figure 3 It shows from Figure 2 A three-dimensional view of the state after removing the DCA from the lower chamber. Figure 4 It shows from Figure 3 A 3D view showing the state after removing the lower fixed chuck DCHK and the lower worktable DSTG.

[0086] refer to Figure 3 and Figure 4 In this embodiment of the invention, the alignment assembly ALG can be connected to the lower worktable DSTG, so that the alignment assembly ALG can align the position between the lower material DMT and the upper material UMT by adjusting the position of the lower material DMT.

[0087] The alignment assembly ALG can adjust the position of the lower material DMT on a plane formed by the first and second directions. Accordingly, when viewed from the plane, the position of the lower material DMT can be aligned with the position of the upper material UMT.

[0088] The alignment assembly ALG may include a first alignment part ALG1 and a second alignment part ALG2. The first alignment part ALG1 can move the lower worktable DSTG along a first direction DR1 and can align the positions between the upper material UMT and the lower material DMT.

[0094] The substrate BASP can be arranged on the support frame SUF. In embodiments of this invention, the substrate BASP can be quadrilateral, but is not limited thereto.

[0095] The drive unit MOT can be disposed on the substrate BASP. Although not shown, a bracket can be fixed to the substrate BASP, and the drive unit MOT can be supported on the edge of the substrate BASP by means of the bracket.

[0096] In embodiments of this utility model, the drive unit MOT can be a concept that includes a power generation structure (motor and screw structure, pneumatic cylinder, hydraulic cylinder, etc.) capable of linear motion.

[0097] The drive unit (MOT) can be connected to the moving guide unit (LKF). The moving guide unit (LKF) can connect the drive unit (MOT) and the connecting component (LKA).

[0098] As an example, in the case where the drive unit MOT includes a motor and a screw structure, the screw can be connected to the drive shaft of the motor. Furthermore, the moving guide LKF can be connected to the screw. If the motor rotates, the screw rotates, and as the screw rotates, the moving guide LKF can move along the length of the screw. At this time, a ball bearing can be arranged inside the moving guide LKF at the part that meshes with the screw. The ball bearing can reduce friction between the screw and the moving guide LKF and ensure smooth rotation of the screw.

[0099] As another example, when the drive unit MOT includes a pneumatic cylinder or a hydraulic cylinder, the movement guide LKF can be connected to the rod of the pneumatic or hydraulic cylinder. If the pneumatic cylinder is operated, the rod of the pneumatic cylinder can move linearly. Accordingly, the movement guide LKF can move linearly along the length of the rod.

[0100] In the first moving unit MOV1, the moving guide LKF can move along the first direction DR1. In the second moving unit MOV2, the moving guide LKF can move along the second direction DR2.

One end of the connecting beam LKB can be connected to the moving guide LKF, and the other end of the connecting beam LKB can be connected to the first slider ALH2 of the first alignment guide ALH, which will be described later.

[0104] Refer again Figure 2The bellows tube BEL can be arranged between the moving guide LKF and the lower chamber DCA. The connecting beam LKB can be arranged inside the bellows tube BEL. One end of the bellows tube BEL can be bolted to the moving guide LKF, and the other end of the bellows tube BEL can surround the outer periphery of the chamber orifice DCA1 and be bolted to the outer wall of the lower chamber DCA.

[0105] The bellows (BEL) can expand and contract along its length. As an example, the bellows (BEL) can be a corrugated tube with multiple folds formed along its length. The bellows (BEL) can seal the chamber orifice DCA1.

[0106] The upper chamber UCA and the lower chamber DCA combine to form a sealed chamber space SPE. When the chamber space SPE is made into a vacuum state, the bellows BEL can seal the chamber orifice DCA1, thus maintaining the vacuum state of the chamber space SPE.

[0107] refer to Figure 5b The alignment component ALN can be arranged inside the lower chamber DCA on the lower main body DB. Furthermore, the alignment component ALN can be connected to the lower part of the lower worktable DSTG.

[0110] The first alignment unit ALN1 and the second alignment unit ALN2 can be connected to the moving part MOV via the connecting part LKA. When the moving part MOV is operated, the first alignment unit ALN1 and the second alignment unit ALN2 move, thereby adjusting the position of the lower worktable DSTG.

[0111] The third alignment unit ALN3 can be arranged between the lower main body DB and the lower worktable DSTG, and the position of the lower worktable DSTG can be adjusted on the plane formed by the first direction DR1 and the second direction DR2.

[0112] The third alignment unit ALN3 can be separated from the moving part MOV.

[0113] The alignment component ALN may include a first alignment guide ALH, a second alignment guide ALU, and a bearing unit BAU.

[0114] That is, each of the first alignment unit ALN1 and the second alignment unit ALN2 may include a first alignment guide ALH, a second alignment guide ALU, and a bearing unit BAU.

[0115] The first alignment guide ALH can be disposed on the lower body DB. The first alignment guide ALH may include a first track ALH1 and a first slider ALH2. Here, a track groove RAHL can be formed at the upper end of the lower body DB.

[0125] That is, on the plane formed by the first direction and the second direction, the first alignment guide ALH and the second alignment guide ALU can be arranged at right angles to each other.

[0126] Furthermore, the first alignment guide ALH constituting the first alignment unit ALN1 and the first alignment guide ALH constituting the second alignment unit ALN2 can be arranged in directions perpendicular to each other on the plane formed by the first direction DR1 and the second direction DR2.

[0127] Furthermore, the second alignment guide ALU constituting the first alignment unit ALN1 and the second alignment guide ALU constituting the second alignment unit ALN2 can be arranged in directions perpendicular to each other on the plane formed by the first direction DR1 and the second direction DR2.

Specifically, the bearing unit BAU can be arranged on the second slider ALU2. In embodiments of this invention, the bearing unit BAU can be a crossed roller bearing, but is not limited thereto. When the lower worktable DSTG moves along the front-back and left-right directions on the plane formed by the first direction DR1 and the second direction DR2, the bearing unit BAU can support the minor swaying and rotation that may occur during the movement of the lower worktable DSTG. In addition, the bearing unit BAU can support the load of the lower worktable DSTG.

[0129] Here, the lower main body DB and the lower worktable DSTG can be connected by fastener DSTG3. Fastener DSTG3 can be a bolt, but is not limited to this.

[0130] refer to Figure 4 and Figure 5b The alignment component ALN may also include a link LNR, which may include a first link LNR1 and a second link LNR2.

[0131] The first alignment unit ALN1 may include multiple first alignment units ALN1a and ALN1b, and the second alignment unit ALN2 may include multiple second alignment units ALN2a and ALN2b.

[0132] Multiple first alignment units ALN1a, ALN1b and multiple second alignment units ALN2a, ALN2b can be arranged on the edge side of the lower main body DB. Furthermore, a third alignment unit ALN3 can be arranged on the central side of the lower main body DB.

[0133] In one embodiment of the alignment unit ALN, four first alignment units ALN1 can be arranged, two second alignment units ALN2 can be arranged, and one third alignment unit ALN3 can be arranged.

[0134] Each of the plurality of second alignment units ALN2a, ALN2b can be arranged between a pair of first alignment units ALN1a, ALN1b with reference to the first direction DR1.

[0135] The first link LNR1 may have a rod shape extending along the first direction DR1. The first link LNR1 may be coupled to the side end of the second track ALU1 of the first alignment unit ALN1.

[0136] Reference Figure 4 and Figure 5b The first link LNR1 can connect a pair of first alignment units ALN1a and ALN1b that are spaced apart from each other along the first direction DR1.

[0137] An upwardly protruding arched portion LNR1a can be formed on the central side of the first link LNR1. The connecting beam LKB, which is connected to the second moving unit MOV2, can pass through the lower part of the arched portion LNR1a and connect to the second alignment unit ALN2.

[0140] If the first moving unit MOV1 is driven according to the above structure, multiple first alignment units ALN1a and ALN1b can move together along the first direction DR1. Furthermore, if the second moving unit MOV2 is driven, a pair of second alignment units ALN2a and ALN2b and a third alignment unit ALN3 can move together along the second direction DR2.

Furthermore, one third alignment unit ALN3 can be provided. The first link LNR1 and the second link LNR2 can be excluded.

[0143] Unlike one embodiment of the alignment unit ALN, when viewed from a plane, a pair of first alignment units ALN1a and ALN1b can be arranged diagonally opposite each other.

Moreover, the pair of first alignment units ALN1a and ALN1b can be respectively connected to a pair of first moving units MOV1, and the pair of second alignment units ALN2a and ALN2b can be respectively connected to a pair of second moving units MOV2.

[0144] The third alignment unit ALN3 can be arranged on the central side of the lower main body DB. Unlike one embodiment of the alignment component ALN, the second link LNR2 is not provided, therefore, the second alignment unit ALN2 and the third alignment unit ALN3 can be separated from each other.

[0145] Therefore, driven by the first moving unit MOV1, the first alignment unit ALN1 can adjust the position of the lower worktable DSTG in the first direction DR1. Driven by the second moving unit MOV2, the second alignment unit ALN2 can adjust the position of the lower worktable DSTG in the second direction DR2.

[0146] At this time, the third alignment unit ALN3 can be separated from the moving part MOV and the second alignment unit ALN2.

[0147] The laminating apparatus LAM according to an embodiment of the present invention is configured as described above. The method of laminating the upper material UMT and the lower material DMT using the above-described laminating apparatus LAM will be described below.

[0148] Figure 7 This is a process flow diagram illustrating a method for laminating upper material UMT and lower material DMT using a laminating apparatus LAM according to an embodiment of the present invention.

[0149] refer to Figure 7The lamination method according to an embodiment of the present invention may include the following steps: arranging an upper material UMT inside the upper chamber UCA and arranging a lower material DMT inside the lower chamber DCA (S1); sealing the upper chamber UCA and the lower chamber DCA to form a chamber space SPE (S2); forming the chamber space SPE into a vacuum state (S3); aligning the upper material UMT and the lower material DMT (S4); and laminating the upper material UMT and the lower material DMT (S5).

[0150] In step S1, where the upper material UMT is arranged inside the upper chamber UCA and the lower material DMT is arranged inside the lower chamber DCA, refer to... Figure 1 The upper material UMT can be attached to the upper fixed chuck UCHK. The upper material UMT can be conveyed to the upper fixed chuck UCHK using a separate conveying device. In one embodiment of the upper fixed chuck UCHK, current is supplied to the upper fixed chuck UCHK to generate electrostatic force, thereby allowing the upper material UMT to be attached or attracted.

[0151] The lower material DMT can be attached to the lower fixed chuck DCHK. The lower material DMT can be conveyed to the lower fixed chuck DCHK using a separate conveying device. In one embodiment of the lower fixed chuck DCHK, current is supplied to the lower fixed chuck DCHK to generate electrostatic force, thereby allowing the lower material DMT to be attached or attracted.

[0152] In step S2, which forms the chamber space SPE by sealing the upper chamber UCA and the lower chamber DCA, refer to Figure 1 The upper chamber UCA can be moved toward the lower chamber DCA by driving the first lifting unit HHU1. The upper chamber UCA and the lower chamber DCA can be combined to form a sealed chamber space SPE.

[0153] In step S3, which forms the chamber space SPE into a vacuum state, reference is made to... Figure 1 The vacuum forming unit (VAC) creates a vacuum inside the chamber space SPE by venting the gas inside the chamber space SPE. An example of the vacuum forming unit (VAC) may include a vacuum pump and necessary components, but is not limited thereto.

[0154] In step S4, which aligns the upper material UMT and the lower material DMT, refer to Figure 1 The upper imaging unit UCAM and the lower imaging unit DCAM can capture or measure the alignment status between the upper material UMT and the lower material DMT.

[0155] The upper imaging unit UCAM can capture or measure the alignment position between the upper material UMT and the lower material DMT through the upper vision window UW, the upper hole USTG1, and the upper marking hole UMHL.

[0156] The lower imaging unit DCAM can capture or measure the alignment position between the lower material DMT and the upper material UMT through the lower vision window DW, the lower hole DSTG1, and the lower marking hole DMHL.

[0157] If, when viewed from a plane, the upper material UMT and the lower material DMT are not aligned in the same position, the position of the lower material DMT can be adjusted by operating the alignment assembly ALG.

[0158] That is, by driving the moving part MOV, the alignment part ALN can adjust the position of the lower worktable DSTG, the lower fixed chuck DCHK, and the lower material DMT on the plane formed by the first direction DR1 and the second direction DR2.

[0159] Specifically, the first moving unit MOV1 can move the first alignment unit ALN1 to align the lower material DMT and the upper material UMT in the first direction DR1. The second moving unit MOV2 can move the second alignment unit ALN2 to align the lower material DMT and the upper material UMT in the second direction DR2.

[0160] Step S5 of laminating the upper material UMT and the lower material DMT is referred to Figure 1 When viewed from a plane, if the upper material UMT and the lower material DMT are located in the same position when photographed or measured, the second lifting unit HHU2 can be driven to move the upper worktable USTG towards the lower worktable DSTG.

[0161] Accordingly, the upper material UMT can move in the direction of the lower material DMT, and the upper material UMT and the lower material DMT can be laminated together.

[0162] The lamination apparatus LAM according to embodiments of the present invention can reduce alignment errors between laminating materials in the manufacturing process of display devices through the above-described configuration and lamination method. Furthermore, the alignment position between the laminating materials can be adjusted after the chamber space for the lamination process is evacuated to prevent misalignment of the laminating materials during vacuum formation. This ultimately improves the lamination accuracy of the lamination process and increases the yield and productivity of display devices.
