Description

Technical Field

[0001] This invention relates to the field of displays, and more particularly to a mounting apparatus for three-dimensional display films. Background Technology

[0002] In existing technologies, LED displays consist of tens of thousands or even hundreds of thousands of LED beads. To achieve passive 3D display, after the LED beads are soldered and assembled onto the PCB board, a 3D display film needs to be applied to the upper surface of the LED beads. This 3D display film is typically a polarizing film, including left-handed and right-handed polarizing films (or two types of linearly polarized films at a 90-degree angle). If the two polarizing films are alternately applied to the LED beads in a checkerboard pattern, precise application is very difficult due to the small size of both the beads and the film, especially when the display density is high and the beads are small, resulting in even greater difficulty and lower yield. Therefore, a suitable device is needed to achieve efficient and accurate application of the 3D display film. Summary of the Invention

[0003] This invention provides a mounting device for three-dimensional display films, solving the problem of how to independently, efficiently, and accurately mount three-dimensional display patches on each LED bead in a display module.

[0004] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is to provide a mounting device for a three-dimensional display film, characterized in that: it includes an operating table, a first movable platform and a second movable platform disposed on the operating table, a first observation lens, a second observation lens, a gripping mechanism, and a dispensing mechanism; the first movable platform is used to place the three-dimensional display patch, and the first observation lens is located above the first movable platform for observing and identifying the three-dimensional display patch; the second movable platform is used to place the display module, and the second observation lens is located above the second movable platform for observing and identifying the LED beads on the display module; the gripping mechanism includes a rotating swing arm and a suction nozzle disposed below the front end of the rotating swing arm; the gripping mechanism is used to grip the three-dimensional display patch from the first movable platform and then move it to place on the corresponding LED bead of the display module on the second movable platform; the dispensing mechanism includes a dispensing arm and a dispensing head disposed below the front end of the dispensing arm, and the dispensing mechanism is used to apply adhesive to the display module.

[0005] Preferably, there are multiple three-dimensional display patches, which are uniformly cut from a three-dimensional display film and carried on a blue film. The blue film is uniformly stretched and expanded and then fixed. The three-dimensional display patches have equal intervals between them.

[0006] Preferably, the gripping mechanism further includes a first lifter and a first rotator disposed at the rear end of the rotating arm, wherein the first lifter drives the rotating arm to move up and down, and the first rotator drives the rotating arm to rotate and swing.

[0010] Preferably, the first observation lens is detachably mounted with a polarizing lens whose polarization direction is opposite to that of the three-dimensional display patch.

[0011] Preferably, the system further includes a processor.

After the second observation lens takes a picture of the display module to obtain a second observation image, the processor performs image recognition processing on the second observation image to calculate the distance interval between the LEDs of the display module, thereby setting the single-step movement step value of the second moving platform carrying the display module accordingly.

[0012] Preferably, a display screen is included, which is electrically connected to the first observation lens and the second observation lens, and is used to display the three-dimensional display patch observed by the first observation lens and the display module observed by the second observation lens.

Detailed Implementation

[0015] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0016] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0017] like Figure 1 As shown, the mounting equipment for the three-dimensional display film includes an operating table 1, a first movable stage 2 and a second movable stage 3 mounted on the operating table 1, a first observation lens 4 and a second observation lens 5, a gripping mechanism 6 and a dispensing mechanism 7.

[0018] The first mobile platform 2 has a first operating mechanism and a second operating mechanism that operate perpendicularly to each other. For example, the first operating mechanism is located above the second operating mechanism. The first operating mechanism can move laterally, and the second operating mechanism can drive the first operating mechanism to move longitudinally, so that the first mobile platform 2 as a whole can move laterally and longitudinally.

[0019] Furthermore, the first movable stage 2 is used to place three-dimensional display patches. The first movable stage 2 has multiple three-dimensional display patches, which are uniformly cut from the three-dimensional display film 9 and supported on the blue film 11. The blue film 11 is uniformly stretched and expanded and then fixed, resulting in equal intervals between the three-dimensional display patches. The single-step movement of the first movable stage 2 carrying the three-dimensional display patches corresponds to the distance interval between the three-dimensional display patches.

[0020] The first observation lens 4 is located above the first moving platform 2 and is used to identify the three-dimensional display patch.

[0021] Furthermore, in this invention, the three-dimensional display film 9 is a polarizing film, including two types: a left-handed polarizing film 91 and a right-handed polarizing film 92. For example... Figure 2 As shown, the entire left-hand polarizing film 91 is applied to the blue film 11. The left-hand polarizing film 91 is cut, and then the blue film 11 is uniformly stretched and expanded before being fixed, so that the left-hand polarizing film 91 separates into multiple left-hand polarizing patches 93 arranged in a uniform manner. Similarly, when the entire right-hand polarizing film 92 is applied to the blue film 11, the right-hand polarizing film 92 is cut, and then the blue film 11 is uniformly stretched and expanded before being fixed, so that the right-hand polarizing film 92 separates into multiple right-hand polarizing patches 94 arranged in a uniform manner.

[0022] Because the 3D display film 9 is transparent, a clear image of it cannot be captured by a conventional lens. This prevents the lens and gripping mechanism from accurately identifying and gripping the 3D display patch, severely impacting efficiency and yield. Therefore, a polarizing lens 41 with the opposite polarization direction to the 3D display film 9 is provided on the first observation lens 4. The polarizing lens 41 has an observation film that can clearly identify the 3D display film 9. For example, when the 3D display film 9 is a left-handed polarizing film 91, the observation film is a right-handed polarizing film; when the 3D display film 9 is a right-handed polarizing film 92, the observation film is a left-handed polarizing film. In this way, the 3D display film 9 can be identified within the first observation lens 4.

[0023] Preferably, a yellow light is also provided in the first movable stage 2. The light emitted by the yellow light shines on the three-dimensional display patch. Under this light, the three-dimensional display patch appears black under the recognition of the first observation lens 4, with clear edges, which is convenient for positioning and recognition.

[0024] Preferably, the three-dimensional display film 9 can also be two linearly polarized films, with the polarization directions of the two linearly polarized films forming a 90-degree angle; when the two linearly polarized films form a 90-degree angle with each other, the visual effect is the same as that brought by the left-handed polarizing film 91 and the right-handed polarizing film 92.

[0025] Furthermore, such as Figure 3As shown, the polarizing lens 41 is detachably connected to the first observation lens 4. There are two types of polarizing lenses 41: one containing a left-handed polarizing film and the other containing a right-handed polarizing film.

[0026] Furthermore, the second mobile platform 3 also includes a first operating mechanism and a second operating mechanism that operate perpendicularly to each other; for example, the first operating mechanism is located above the second operating mechanism, the first operating mechanism can move laterally, and the second operating mechanism can drive the first operating mechanism to move longitudinally, so that the second mobile platform 3 as a whole can move laterally and longitudinally.

[0027] The second movable platform 3 is used to place the display module 10, which has multiple LEDs with equal spacing between them. The second movable platform 3 carries the display module 10 in single-step movement, corresponding to the distance between the LEDs of the display module 10.

[0028] Furthermore, the second observation lens 5 is located above the second moving platform 3 and is used to identify the display module 10.

[0029] Furthermore, the gripping mechanism 6 is used to grip the 3D display film 9 and place it on the display module 10. For example... Figure 4 and Figure 5 As shown, the gripping mechanism 6 includes a rotating arm 61 and a suction nozzle 62 disposed below the rotating arm 61; the rotating arm 61 can swing back and forth between the first moving platform 2 and the second moving platform 3, and the suction nozzle 62 is used to pick up the three-dimensional display patch above the first moving platform 2.

[0030] Preferably, the gripping mechanism 6 further includes a first lifter 63 and a first rotator 64 disposed at the rear end of the rotating arm 61. The first lifter 63 drives the rotating arm 61 to move up and down, and the first rotator 64 drives the rotating arm 61 to rotate and swing. The gripping mechanism 6 reciprocates between a first rotational position 66 above the first moving platform 2 and a second rotational position 65 above the second moving platform 3 at a first fixed angle α.

[0031] When the first rotator 64 drives the rotating arm 61 to rotate to the first rotation position 66, the first lifter 63 drives the rotating arm 61 to move downward, and picks up the three-dimensional display patch above the first moving platform 2 through the suction nozzle 62; then the first lifter 63 drives the rotating arm 61 to move upward, the first rotator 64 drives the rotating arm 61 to rotate to the second rotation position 65, the first lifter 63 drives the rotating arm 61 to move downward, and places the three-dimensional display patch at the fixed point position on the display module 10.

[0032] The display module 10 has multiple LED beads. The gripping mechanism 6 places the gripped 3D display film 9 on the upper surface of the LED beads, with the area above the LED beads serving as a fixed point on the display module 10. Since the first fixed angle α of the gripping mechanism 6 is fixed, it can only pick up the 3D display patch directly below it through the suction nozzle 62. After the gripping mechanism 6 picks up the 3D display patch and places it on the corresponding fixed point on the display module 10, the rotating arm 61 of the gripping mechanism 6 swings again to above the first moving platform 2. The first moving platform 2 needs to be moved to move the next 3D display patch to be picked up to be directly below the suction nozzle 62 (i.e., the first rotation position 66) for the suction nozzle 62 to pick up.

[0033] Similarly, after a fixed point on the display module 10 completes the mounting of the 3D display patch, the gripping mechanism 6 picks up the 3D display patch and its rotating arm 61 swings again to above the second moving platform 3. The second moving platform 3 needs to be moved to move the next fixed point to be mounted to directly below the nozzle 62 (that is, the second rotation position 65) so that the nozzle 62 can be lowered.

[0034] Preferably, since the 3D display patch is a soft, thin, and difficult-to-pick-up material, the nozzle 62 is a bakelite nozzle, which can quickly pick up the 3D display patch.

[0035] Furthermore, before the gripping mechanism 6 places the gripped 3D display patch on the upper surface of the LED bead, the dispensing mechanism 7 applies adhesive to the display module 10 to facilitate the attachment of the 3D display patch to the fixed point position.

[0036] Preferred, such as Figure 6 and Figure 7 The dispensing mechanism 7 includes a dispensing arm 71 and a dispensing head 72 disposed below the dispensing arm 71. It also includes a second lifter 73 and a second rotator 74 disposed at the rear end of the dispensing arm 71. The second lifter 73 drives the dispensing arm 71 to move up and down, and the second rotator 74 drives the dispensing arm 71 to rotate and swing. The dispensing mechanism 7 reciprocates at a second fixed angle β between a second rotational position 65 above the second moving platform 3 and the adhesive carrier platform 13.

[0037] When the second rotator 74 drives the rotating arm 61 to rotate to the glue carrier platform 13, the second lifter 73 drives the dispensing arm 71 to move downward, and the dispensing head 72 picks up the glue in the glue carrier platform 13; then the second lifter 73 drives the dispensing arm 71 to move upward, the second rotator 74 drives the dispensing arm 71 to rotate to the second rotation position 65, the second lifter 73 drives the dispensing arm 71 to move downward, and the dispensing head 72 injects glue into the fixed point position on the display module 10.

[0038] Furthermore, it also includes a display screen 8, which is electrically connected to the first observation lens 4 and the second observation lens 5; it is used to display the three-dimensional display patch observed by the first observation lens 4 and the display module observed by the second observation lens 5.

[0039] Furthermore, such as Figure 8 As shown, the first observation lens 4 is used to observe the three-dimensional display patch ( Figure 8 (Taking a left-handed polarizing patch 93 as an example) The first observation image P1 is captured and transmitted to the processor of the mounting device. The first observation image P1 can be displayed on the display screen 8.

[0040] The processor performs image recognition processing on the first observation image P1 to calculate the distance between the three-dimensional display patches. For example, it marks the arrangement of left-handed polarizing patches 93 in the first observation image P1. The arrangement is rectangular in shape. Based on this arrangement, the length A1, width B1, and area S1 (S1=A1) of the region occupied by the left-handed polarizing patches 93 are measured. B1), the row spacing H1 and column spacing L1 between two adjacent left-handed polarizing patches 93. This corresponds to setting the single-step movement step value of the first moving stage 2 carrying the 3D display patch.

[0041] Preferred, combined Figure 9 A first coordinate system is established within the first observation image P1, and the coordinates of each left-handed polarizing patch 93 are defined. The lower left corner is the origin of the first coordinate system, and the coordinates of the first coordinate system can be represented as (Xi, Yj), i=0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11; j=0, 1, 2, 3, 4, 5, 6, 7, 8; the coordinates of the left-handed polarizing film 91 at the origin are (X0, Y0); the horizontal coordinate increases to the right in units of column spacing L1, and the maximum value of the horizontal coordinate is X11, indicating that there are 12 left-handed polarizing films 91 on the horizontal coordinate; the vertical coordinate increases upward in units of row spacing H1, and the maximum value of the vertical coordinate is Y8, indicating that there are 9 left-handed polarizing films 91 on the vertical coordinate; here, only the maximum value of the horizontal coordinate is X11 and the maximum value of the vertical coordinate is Y8 as an example, but it is not limited to these values; thus, each left-handed polarizing film 91 will correspond to a coordinate in the first coordinate system.

[0042] Preferred, such as Figure 10As shown, the walking path of the first moving stage 2 and the single-step movement value for each movement are determined based on the row spacing H1 and column spacing L1 of the left-handed polarizing patch 93. It can be seen that the walking path of the first moving stage 2 is S-shaped. The starting point of the first moving stage 2 is the upper right corner, which corresponds to the left-handed polarizing film 91 with coordinates (X0, Y0). The single-step movement value of the first moving stage 2 for each longitudinal movement is J1, J1=H1, and the single-step movement value for each lateral movement is J2, J2=L1.

[0043] Preferably, the gripping mechanism 6 first picks up the left-handed polarizing patch 93 with coordinates (X0, Y0), and then the first moving platform 2 steps along the above-mentioned walking path. The stepping direction of this walking path is relative to the walking direction of the suction nozzle of the gripping mechanism 6, so that the gripping mechanism 6 picks up the left-handed polarizing patches 93 with coordinates (X0, Y1) up to (X0, Y9) in sequence; and then picks up the left-handed polarizing patches 93 with coordinates (X1, Y9) up to (X1, Y0) until all the required left-handed polarizing patches 93 are picked up.

[0044] Furthermore, such as Figure 11 As shown, the second observation lens 5 is used to capture images of the display module 10, obtain a second observation image P2, transmit the second observation image P2 to the processor of the mounting device, and the second observation image P2 can be displayed on the display screen 8.

[0045] The processor performs image recognition processing on the second observation image P2 to calculate the distance between the LEDs in the display module 10. For example, it marks the arrangement of fixed points 12 on the display module 10 within the second observation image P2. The arrangement is rectangular in shape. Based on this arrangement, the length A2, width B2, and area S2 (S2=A2) of the area occupied by the display module 10 are measured. B2), the row spacing H2 and column spacing L2 between two adjacent fixed points 12. Correspondingly, the single-step movement step value of the second moving platform 3 supporting the display module is set.

[0046] Preferred, combined Figure 12A second coordinate system is established within the second observation image P2, and the coordinates of each fixed point 12 are defined. The coordinates of the second coordinate system can be represented as (Tq, Sr), where q = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11; r = 0, 1, 2, 3, 4, 5, 6, 7; the lower left corner is the coordinate of the origin fixed point 12 (T0, S0). The horizontal coordinate increases to the right in units of one column spacing L2, with the maximum value of the horizontal coordinate being T11, indicating that there are 12 fixed points 12 on the horizontal coordinate. The vertical coordinate increases upward in units of one row spacing H2, with the maximum value of the vertical coordinate being S7, indicating that there are 8 fixed points 12 on the vertical coordinate. Here, we only use the maximum value of the horizontal coordinate being T11 and the maximum value of the vertical coordinate being S7 as an example, but it is not limited to these values. Thus, each fixed point 12 will correspond to a coordinate in the second coordinate system.

[0047] Select the coordinates of the fixed point 12 where the left-handed polarizing patch 93 needs to be pasted in the second coordinate system, so that after pasting, it appears as... Figure 13 The chessboard shape is shown. Select the coordinates of the fixing point 12 where the right-hand polarizing film 94 needs to be pasted, so that after pasting, it forms a chessboard shape. Figure 16 The chessboard shape shown.

[0048] The coordinates of the fixed points 12 where the left-handed polarizing patch 93 needs to be pasted have the following characteristics: when the value of Tq is odd, the value of Sr is even, and when the value of Tq is even, the value of Sr is odd. For example, in the first column of the display module, the coordinates of the fixed points where the three-dimensional display film 9 (left-handed polarizing film 91) needs to be pasted are (T0, S1), (T0, S3), (T0, S5), and (T0, S7); in the second column of the display module, the coordinates of the fixed points where the three-dimensional display film 9 (left-handed polarizing film 91) needs to be pasted are (T1, S0), (T1, S2), (T1, S4), and (T1, S6).

[0049] The coordinates of the fixing points 12 where the right-hand polarizing patch 94 needs to be pasted have the following characteristics: when the value of Tq is even, the value of Sr is also even; when the value of Tq is odd, the value of Sr is also odd. For example, in the first column of the display module, the coordinates of the fixing points where the right-hand polarizing film 92 needs to be pasted are (T0, S0), (T0, S2), (T0, S4), and (T0, S6); in the second column of the display module, the coordinates of the fixing points where the right-hand polarizing film 92 needs to be pasted are (T1, S1), (T1, S3), (T1, S5), and (T1, S7).

[0050] Therefore, the first travel path of the left-handed polarizing patch 93 of the second moving platform 3 and the distance of each travel can be determined based on the row spacing H2 and column spacing L2 between the fixed points 12; and the second travel path of the right-handed polarizing patch 94 of the second moving platform 3 and the distance of each travel can be determined based on the row spacing H2 and column spacing L2 between the fixed points 12.

[0051] Preferred, such as Figure 14 As shown, the first travel path of the second moving platform 3 is S-shaped. The starting point of the second moving platform 3 is the upper right corner, which corresponds to the fixed point with coordinates (S0, T0). The second moving platform 3 has two longitudinal movement distances, namely J3 and J4, J3=H2, J4=2H2, and the lateral movement distance each time is J5, J5=L2.

[0052] Preferably, the starting position of the second moving platform 3 is a fixed point with coordinates (T0, S0) in the second coordinate system. Since the gripping mechanism 6 needs to place the left-handed polarizing patch 93 with coordinates (X0, Y0) in the first coordinate system onto the fixed point with coordinates (T0, S1) in the second coordinate system, the second moving platform 3 needs to move longitudinally a distance of J3 before placing the left-handed polarizing patch 93. Then, the gripping mechanism 6 picks up the left-handed polarizing patch 93 with coordinates (X0, Y1) in the first coordinate system and places it onto the fixed point with coordinates (T0, S3) in the second coordinate system, and the second moving platform 3 needs to move longitudinally a distance of J4. According to the first walking path of the second moving platform 3, the left-handed polarizing patch 93 on the display module is finally positioned... Figure 13 The diagram shows a checkerboard-shaped distribution.

[0053] Furthermore, after the left-handed polarizing patch 93 is mounted on the display module 10, the type of the three-dimensional display film 9 is changed to a right-handed polarizing patch 94 on the first moving platform; then, the right-handed polarizing patch 94 is photographed through the first observation lens 4, and the first observation image P1 is obtained again. A first coordinate system is established in the first observation image P1, and the coordinates of each right-handed polarizing patch 94 are defined, and the walking path of the first moving platform 2 is planned. This part is consistent with the above content and will not be repeated here.

[0054] Furthermore, in combination Figure 15 The second travel path of the second moving platform 3 is also S-shaped. The starting point of the second moving platform 3 is the upper right corner, which corresponds to the fixed point with coordinates (T0, S0). The second moving platform 3 has two longitudinal movement distances, namely J3 and J4, J3=H2, J4=2H2, and the lateral movement distance each time is J5, J5=L2.

[0055] Preferably, the starting position of the second moving platform 3 is a fixed point with coordinates (T0, S0) in the second coordinate system; the gripping mechanism 6 needs to place the right-handed polarizing film 92 with coordinates (X0, Y0) in the first coordinate system onto the fixed point with coordinates (T0, S0) in the second coordinate system; then the gripping mechanism 6 will pick up the right-handed polarizing film 92 with coordinates (X0, Y1) in the first coordinate system and place it onto the fixed point with coordinates (T0, S2) in the second coordinate system. The distance that the second moving platform 3 needs to move longitudinally is J4. According to the second travel path of the second moving platform 3, the right-handed polarizing patch 94 on the display module is finally made to appear as... Figure 16 The diagram shows a checkerboard-shaped distribution; ultimately, the left-handed polarizing film 91 and the right-handed polarizing film 92 on module 10 form an alternating checkerboard shape. It can be seen that in this invention, each LED is individually mounted above it. The left-hand polarizing patch 93 or the right-hand polarizing patch 94 can be replaced individually when the LED bead or its attached left-hand polarizing patch 93 or right-hand polarizing patch 94 is damaged. This makes it easy to use and reduces maintenance costs.

[0056] Furthermore, such as Figure 17 As shown, the left-handed polarizing film 91 and the right-handed polarizing film 92 on the display module 10 can also be mounted in an alternating stripe pattern.

[0057] Furthermore, the present invention also discloses a method for attaching a three-dimensional display film, including... Step 1: Cut the 3D display film applied to the blue film, and then expand the blue film to separate the 3D display film into multiple 3D display patches that are evenly arranged. Step 2: Place the blue film on the first moving platform and identify the 3D display patch through the first observation lens. The first observation lens is equipped with an identification film for identifying the 3D display patch. Step 3: Place the display module on the second moving platform and identify multiple fixed points of the display module through the second observation lens; Step 4: The gripping mechanism picks up the 3D display patch, the dispensing mechanism dispenses glue into the corresponding fixed point, and then the gripping mechanism places the 3D display patch into the corresponding fixed point. Step 5: Repeat step 4 until all fixed points have been fitted with the 3D display patch; Step 6: Check whether the 3D display patches on the display module are installed according to specifications; Step 7: Correct any improperly installed 3D display patches based on the test results; Step 8: Curing the 3D display patch.

[0058] Preferably, in step two, the three-dimensional display patch is photographed through the first observation lens to obtain a first observation image; the arrangement and distribution of the three-dimensional display patch is marked in the first observation image to determine the row spacing and column spacing between the three-dimensional display patches; then, the walking path of the first moving platform and the distance of each movement are determined according to the row spacing and column spacing of the three-dimensional display patch.

[0059] Preferably, a first coordinate system is established within the first observation image, and the coordinates of each three-dimensional display patch are defined.

[0060] Preferably, in step three, the display module is photographed through the second observation lens to obtain a second observation image; the arrangement and distribution of the fixed points of the display module are marked in the second observation image to determine the row spacing and column spacing between the fixed points; then the walking path of the second moving platform and the distance of each movement are determined according to the row spacing and column spacing between the fixed points.

[0061] Preferably, a second coordinate system is established within the second observation image, and the coordinates of each fixed point are defined as (Tq, Sr). The coordinates of each fixed point correspond to the coordinates of a three-dimensional display patch.

[0062] Preferably, the three-dimensional display film includes a left-handed polarizing film and a right-handed polarizing film, and the three-dimensional display patch correspondingly includes a left-handed polarizing patch and a right-handed polarizing patch.

[0063] Preferably, the three-dimensional display film can also be two linearly polarized films, with the polarization directions of the two linearly polarized films forming a 90-degree angle; when the two linearly polarized films form a 90-degree angle with each other, the visual effect is the same as that brought by left-handed and right-handed polarized films.

[0064] Preferably, in the coordinates of the fixed point used for mounting the left-handed polarizing patch, when the Ti value of the fixed point coordinate is odd, the Sr value is even; when the Ti value of the fixed point coordinate is even, the Sr value is odd. In the coordinates of the fixed point used for mounting the right-handed polarizing patch, when the Ti value of the fixed point coordinate is odd, the Sr value is odd; when the Ti value of the fixed point coordinate is even, the Sr value is even.

[0065] Preferably, a first travel path of the second moving stage is fitted based on the coordinates of the fixed point used to mount the left-hand polarizing patch; and a second travel path of the second moving stage is fitted based on the coordinates of the fixed point used to mount the right-hand polarizing patch.

[0066] Preferably, in step six, the display module is photographed through the second observation lens to obtain a third image; the left-handed and right-handed polarizing patches are detected in the third image to ensure they are properly installed.

[0067] Preferably, in step seven, the non-standard 3D display patches include 3D display patches with problems such as incorrect installation, missing parts, or misalignment.

[0068] Preferably, in step eight, the light-transmitting adhesive on each LED bead is fully cured, so that the 3D display patch is firmly bonded to the LED bead. Depending on the type of light-transmitting adhesive, natural curing, heat curing, and light curing can be used. It should be noted that when heat curing is used, the curing temperature should be below 90°C to avoid damage to the 3D display patch due to excessive temperature.
