[0002] At present, the surface of most optical modules is equipped with multiple groups of optical microstructure units by matching the structural setting of optical film materials (such as prism films, naked-eye grating films, microlens array films, etc.). These optical microstructure units can diffuse, shape, make uniform, focus, image, and other modulations of the incident light beam of the optical module by adjusting their shape, focal length, arrangement, duty cycle and other parameters, so that the optical module can display specific optical effects. However, in actual use, it is found that the structural setting of this optical microstructure unit is easily affected by the expansion and contraction of the material of the optical film material itself, resulting in the pre-arrangement of the optical microstructure in the film material being offset, and then causing the alignment deviation between the optical microstructure and the module pixel, which seriously affects the optical display effect of the optical module. For this reason, in the related application, a technical means is provided to independently set multiple optical microstructures on the optical module, and an auxiliary tool is urgently needed to complete the corresponding installation operation.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0025] In one embodiment, Figure 1 As shown, the embodiment of the present application provides an adsorption laminating device 100, which may specifically include an adsorption material collection mechanism 110 and an image acquisition mechanism 120, wherein the image acquisition mechanism 120 is mainly used to take photos of the optical microstructure to be installed to identify the type and placement angle of the optical microstructure. The adsorption material collection mechanism 110 is mainly used to transfer the optical microstructure to the target position of the optical module at a target angle by adsorption material collection according to the type and placement angle of the optical microstructure.

[0026] It is understandable that the adsorption and laminating device 100 of the embodiment of the present application is mainly used in the installation operation of the optical microstructure of the optical module. Since the structure of the independently arranged optical microstructure is relatively small and cannot be directly installed manually, the adsorption and laminating device of the embodiment of the present application is required to assist in the completion. The optical module in which the optical microstructure is installed is assisted by the adsorption and laminating device 100 of the embodiment of the present application, and its specific structure is as follows: a plurality of independently arranged optical microstructures are arranged on the display surface of the optical module, each optical microstructure corresponds to at least one pixel point, and all optical microstructures are arranged above at least one corresponding pixel point, and an optical microstructure is arranged above all pixels. The optical microstructure may specifically include any one or any several of a wide-viewing angle microstructure, a brightening microstructure, a 3D depth of field microstructure, and a photochromic microstructure. In this way, according to the actual optical effect display needs of the optical module, differentiated placement of multiple types of optical microstructures can be performed to achieve a variety of optical functions such as wide viewing angle, brightening, or parallax effect. According to the actual optical display effect requirements of the optical module, it is necessary to place optical microstructures of different types and / or at different placement angles at different positions of the optical module, so the image acquisition mechanism 120 is required to perform photo recognition to ensure that the corresponding optical microstructure is transferred and installed at the corresponding target position of the optical module at the corresponding target angle. Generally speaking, the image acquisition mechanism 120 can be any one of a CCD camera, a CMOS camera, an EMCCD camera, and an sCMOS camera.

[0027] In addition, the above-mentioned adsorption material-collecting method specifically refers to that the adsorption material-collecting mechanism 120 absorbs each optical microstructure to be installed by adsorption, so as to transfer each optical microstructure to be installed to the target position of the optical module at a target angle.

[0028] In this way, the adsorption and laminating device 100 of the embodiment of the present application, through the above-mentioned structural setting, can accurately transfer each optical microstructure to be installed to the target position of the optical module at the target angle through the cooperation of the adsorption and material taking mechanism 110 and the CCD camera 120, so that the optical microstructures are independently arranged above at least one corresponding pixel point, ensuring the accurate alignment between the optical microstructures and the module pixels in the optical module, and the installation and fixation of each optical microstructure will not be affected by the installation and fixation of other optical microstructures, nor will it be affected by the spacing between the pixels of the optical module. In this way, the installation and fixation method of the optical microstructure assisted by the adsorption and laminating device 100 can realize the independent setting of multiple optical microstructures on the optical module, so that it will not be affected by the expansion and contraction of the optical film material and the alignment deviation between the optical microstructure and the module pixel will not occur, and it will not be due to the need to install optical modules with different pixel spacings, and the need to re-open the mold to make the optical film material according to the pixel spacing will cause the mold cost to increase exponentially.

[0029] In some examples, such as Figure 1 As shown, the suction and material-collecting mechanism 110 includes a suction nozzle module 111, a turret 112, and a material-collecting arm 113 capable of spatial three-axis motion. The suction nozzle module 111 is rotated and installed at the operating end of the material-collecting arm 113 through the turret 112. Thus, through the above-mentioned structural setting, when the material-collecting arm 113 drives the suction nozzle module 111 to approach the optical microstructure to be installed by performing spatial three-axis motion, the optical microstructure to be installed can be sucked up by starting the suction nozzle module 111. Then, the material-collecting arm 113 drives the suction nozzle module 111 to drive the optical microstructure to be installed to the target position corresponding to the optical module by performing spatial three-axis motion, and performs corresponding transfer installation, so that the optical microstructure to be installed is transferred to the target position corresponding to the installation optical module.

[0030] It is understandable that the nozzle module 111 can be a conventional vacuum nozzle module to achieve the suction transfer of the optical microstructure to be installed by vacuum adsorption. The material picking arm 113 can be a conventional mechanical arm capable of three-axis spatial motion, which can be driven by a motor or a cylinder to achieve arbitrary movement in the X-axis direction, the Y-axis direction, and the Z-axis direction. The turret 112 can include a rotary motor to drive the nozzle module 111 to rotate to any angle to adjust the placement angle of the optical microstructure to be installed sucked up by the nozzle module 111.

[0031] In some examples, such as Figures 1 to 3As shown, the nozzle module 111 includes a nozzle bracket 1111 and at least one nozzle 1112. The top of the nozzle bracket 1111 is rotatably installed at the operating end of the material picking arm 113 through the turret 112, and at least one nozzle 1112 is installed at the bottom end of the nozzle bracket 1111. In this way, through the above-mentioned structural arrangement, at least one nozzle 1112 can rotate synchronously with the rotation of the nozzle bracket 1111. Further, the nozzle module 111 may specifically include two or more nozzles 1112, and the two or more nozzles 1112 are arranged in a straight line or in a ring or in an array at the bottom end of the nozzle bracket 1111. In this way, through the structural arrangement of two or more nozzles 1112, it is possible to simultaneously transfer and install two or more optical microstructures, thereby greatly improving the processing efficiency of the optical module. At the same time, two or more suction nozzles 1112 are arranged in a straight line or in a ring or in an array at the bottom of the suction nozzle holder 111, which can meet the processing requirements of optical modules with different optical microstructure layouts. Furthermore, the suction nozzle module 111 may specifically include two or more different suction nozzles 1112, and two or more different suction nozzles 1112 are arranged in a straight line or in a ring or in an array at the bottom of the suction nozzle holder 111. In this way, through the above-mentioned structural setting, when different types of optical microstructures need to be arranged on the surface of the module, and different suction nozzles 1112 need to be used for adsorption, compared with the existing suction nozzle assembly that can only absorb a single type of optical microstructure at a time, it is necessary to stop the machine to replace different suction nozzles, resulting in low production efficiency. The suction nozzle module 111 in this example can use different suction nozzles 1112 to absorb different types of optical microstructures at the same time, so that its production efficiency is greatly improved.

[0032] In some examples, such as Figures 1 to 3 As shown, each suction nozzle 1112 is installed at the bottom of the suction nozzle bracket 1111 through a detachable structure. In this way, through the above-mentioned structural setting, it is convenient for relevant personnel to disassemble, assemble and replace each suction nozzle 1112 according to the actual installation requirements of the optical microstructure.

[0033] In some examples, such as Figures 1 to 3 As shown, each suction nozzle 1112 is provided with an adsorption surface adapted to the outer contour of the optical microstructure. In this way, through the above-mentioned structural setting, it is ensured that each suction nozzle 1112 can more stably adsorb the corresponding optical microstructure to be installed, so as to ensure that each optical microstructure is more stably transferred and installed to the target position corresponding to the optical module. Furthermore, the inner contour of the adsorption surface mentioned above can be any one of a plane, a curved surface and a conical surface. In this way, the structural setting of the adsorption surface of different shapes can be used to better meet the adsorption requirements of optical microstructures of different shapes.

[0034] In some examples, such as Figure 3As shown, the adsorption and laminating device also includes a first optical measurement lens 130, which is mainly used to detect the tilt angle of the optical microstructure in the Z-axis direction and perform tilt correction through the adsorption and material collection mechanism 110. It is understandable that when the optical microstructure is transferred and installed to the target position of the optical module, there may be a tilt problem in the Z-axis direction (the Z-axis direction here specifically refers to the direction perpendicular to the display surface of the optical module). At this time, after lighting up the optical module, the first optical measurement lens 130 can be used to measure the luminous light pattern curve of the output light spot of each optical microstructure. Figure 4 As shown, the left side is a schematic diagram of the luminous light pattern curve of a normal light spot, and the right side is a schematic diagram of the luminous light pattern curve of the light spot after tilting (the specific tilt angle is α). In this way, the positioning system of the first optical measurement lens 130 can determine the tilt angle of the optical microstructure in the Z-axis direction by determining the angle between the main axis of the light pattern curve and the normal line of the substrate surface, and then perform tilt correction through the adsorption material picking mechanism 110.

[0035] In some examples, such as Figure 3 As shown, the adsorption and laminating device also includes a second optical measuring lens (not shown), which is used to detect the brightness index of the optical microstructure, and replace the optical microstructure with abnormal brightness index through the adsorption and material taking mechanism. It can be understood that the optical microstructure transferred and installed at the target position of the optical module may have the problem of unqualified brightness. At this time, after lighting up the optical module, the second optical measuring lens can be used to detect the brightness index of each optical microstructure, specifically, to measure its actual brightness and compare it with the standard brightness. If the brightness difference is within ±2%, the optical microstructure is determined to have a normal brightness index. If the brightness difference is greater than ±2%, the optical microstructure is determined to have an abnormal brightness index. In this way, through the detection of the second optical measuring lens, an optical microstructure with abnormal brightness index is found, and the optical microstructure with abnormal brightness index can be replaced through the adsorption and material taking mechanism, that is, the optical microstructure with abnormal brightness index is sucked away by the adsorption and material taking mechanism, and then a new optical microstructure is transferred and installed. After the new optical microstructure is installed, the above-mentioned tilt angle detection and brightness index detection are also required to ensure that the optical microstructure finally installed in the optical module will not have the problem of tilt in the Z-axis direction and abnormal brightness index. Preferably, the second optical measurement lens and the first optical measurement lens 130 are the same optical measurement lens, that is, the optical measurement lens can be used to complete the detection of the tilt angle of the optical microstructure in the Z-axis direction, and the optical measurement lens can also be used to complete the detection of the brightness index of the optical microstructure, so that the overall structural complexity and production cost of the adsorption and bonding device can be effectively reduced.

[0036] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
