Abstract

The application provides a mounting jig of an optical assembly in an optical module and a mounting device. The mounting jig comprises a substrate carrier and a containing groove. The containing groove is arranged on the substrate carrier and is used for containing a substrate. A lap joint platform is arranged in the containing groove. The top surface of the lap joint platform is flush with the top surface of the substrate. The substrate has a mounting end which is arranged close to the lap joint platform. When the substrate is mounted with a material to be mounted, the material to be mounted is partially arranged on the mounting end and partially arranged on the lap joint platform. A glue flow gap is left between the side wall of the substrate and the side wall of the containing groove for the overflow glue to flow. In this way, the part of the material to be mounted protruding from the substrate is no longer arranged in suspension. The top surface of the lap joint platform is flush with the top surface of the substrate, which can ensure that there is no angle difference between the material to be mounted and the substrate after mounting. Meanwhile, the overflow glue can flow along the side wall of the substrate in the glue flow gap and is no longer directly bonded to the substrate and the substrate carrier, thereby improving the mounting efficiency.

Description

Technical Field

[0001] This application relates to the field of optical module mounting technology, specifically to a mounting fixture and mounting equipment for optical components in an optical module. Background Technology

[0002] Optical modules play a crucial role in the field of optical communication. With the large-scale construction of data centers and the rapid development of AI technology, the demand for optical structural components used inside high-speed optical modules is also increasing. The prisms, lenses, glass blocks and other components used in optical structural components need to be mounted on specific substrates or bases, which places high demands on mounting position, mounting deviation, adhesive thickness and mounting angle.

[0003] Currently, manual mounting requires highly skilled operators who need to perform the mounting operation under a microscope. During the bonding process, excess adhesive can stick to the fixtures. Furthermore, during the bonding process between the optical mechanism and the substrate, the optical mechanism extends beyond the substrate, creating a suspended state. This can easily lead to uneven stress on the optical structure during the downward bonding process, resulting in an angle difference between the optical mechanism and the substrate, which affects the performance of the optical module.

The first abutting side has a first protruding section and a first connecting section along the depth direction of the receiving groove. The first protruding section protrudes outward in a direction away from the substrate relative to the first connecting section, and the first protruding section is located above the first connecting section. The first connecting section abuts against the first side and a second adhesive flow gap is formed between the first protruding section and the first side. The second abutting side has a second protruding section and a second connecting section along the depth direction of the receiving groove. The second protruding section protrudes outward in a direction away from the substrate relative to the second connecting section, and the second protruding section is located above the second connecting section. The second connecting section abuts against the second side, and a third adhesive flow gap is formed between the second protruding section and the second side.

[0009] In one embodiment, the substrate has a mounting position, and the substrate and the material to be mounted are mounted at the mounting position. The second and third adhesive flow gaps are located at both ends of the mounting position along the width direction of the receiving groove; and / or, The depth of the receiving groove is adapted to the thickness of the substrate.

[0010] In one embodiment, the mounting fixture further includes: A stage having a carrier receiving section for accommodating a substrate carrier as described above; The mounting assembly is connected to the platform. A motion component, connected to the mounting component, is used to drive the mounting component to apply a force to the material to be mounted.

[0011] In one embodiment, the mounting assembly includes a concave support and a pressure block; The concave support has two support rods spaced apart along the width direction of the receiving groove. The substrate carrier is provided with corresponding engaging parts along the width direction of the receiving groove. The support rods are inserted into the engaging parts one by one, and the bottom surface of the substrate carrier abuts against the carrier receiving part.

[0015] Compared with existing optical structure mounting devices, the mounting fixture for optical components in optical modules provided in this application has the following advantages: This application provides a mounting fixture for optical components in an optical module, including a substrate carrier and a receiving groove. The receiving groove is formed on the substrate carrier for accommodating the substrate. An overlapping platform is provided in the receiving groove, the top surface of which is flush with the top surface of the substrate. The substrate has a mounting end, which is located near the overlapping platform. When the substrate is mounted with the material to be mounted, part of the material to be mounted is located on the mounting end, and part is located on the overlapping platform. Thus, the part of the material to be mounted that protrudes from the substrate is no longer suspended in the air, but is located on the overlapping platform. The top surface of the overlapping platform is flush with the top surface of the substrate, ensuring that the material to be mounted is placed on a horizontal plane. During the mounting process, the material to be mounted will not deflect after being subjected to force. Therefore, there is no angular difference between the mounted material and the substrate, thereby improving the performance of the optical module. At the same time, when the operator places the material to be mounted, the overlapping platform can also be used to position the material to be mounted, further improving the positional accuracy between the material to be mounted and the substrate. In addition, a flow gap is left between the sidewall of the substrate and the sidewall of the receiving groove to allow the overflowing adhesive to flow during the mounting process. The overflowing adhesive can flow along the sidewall of the substrate in the flow gap without directly adhering to the substrate carrier, thereby reducing the frequency of cleaning the substrate carrier and improving mounting efficiency.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] This application provides a mounting device for optical components in an optical module, which typically includes a mounting fixture for the optical components in the optical module, a dispensing device, a vision assist device, and a gripping mechanism.

[0027] The dispensing device is used to precisely and quantitatively apply adhesive to the substrate before mounting, thereby achieving adhesion between the material to be mounted and the substrate. For example, the dispensing device can consist of a stepper motor, a lead screw, and a piston. It can precisely control the rotation speed of the stepper motor and control the movement distance of the piston through the lead screw, thereby achieving high-precision control of the adhesive dispensing amount.

[0028] Visual aids can use cameras and image processing technology to identify the position of the materials to be mounted and the substrate, thereby guiding the mounting structure to perform high-precision alignment and placement; gripping mechanisms can perform pick-up, movement and placement operations, usually operating optical components by vacuum adsorption.

[0029] The mounting fixture for optical components in the optical module is used to accurately carry, position and fix the materials and substrate to be mounted. The improvement of this application embodiment lies in the mounting fixture part of the optical components in the optical module, which mainly includes the following aspects.

[0030] Please refer to Figures 1-2 The mounting fixture for optical components in the optical module includes a substrate carrier 1, a stage 3, a mounting assembly 4, and a motion assembly 5. The stage 3 has a carrier receiving portion 30 for accommodating the substrate carrier 1. The mounting assembly 4 is connected to the stage 3. The motion assembly 5 is connected to the mounting assembly 4 and is used to drive the mounting drill to apply force to the material 21 to be mounted.

[0031] Among them, such as Figures 3-5 As shown, the substrate carrier 1 has a receiving groove 10 for receiving the substrate 2; the receiving groove 10 is provided with an overlapping platform 11, the top surface of the overlapping platform 11 is flush with the top surface of the substrate 2, the substrate 2 has a mounting end 20, the mounting end 20 is located close to the overlapping platform 11, when the substrate 2 is mounted with the material to be mounted 21, part of the material to be mounted 21 is located on the mounting end 20 and part is located on the overlapping platform 11; a glue flow gap (not shown in the figure) is left between the side wall of the substrate 2 and the side wall of the receiving groove 10 to allow overflowing glue to flow.

[0032] In this way, the part of the material to be mounted 21 protruding from the substrate 2 is no longer suspended in the air, but is located on the overlapping platform 11, and the top surface of the overlapping platform 11 is flush with the top surface of the substrate 2, ensuring that the material to be mounted 21 is placed on a horizontal plane. During the mounting process, the material to be mounted 21 will not deflect under force, so there is no angle difference between the mounted material and the substrate 2, thereby improving the performance of the optical module. In addition, a flow gap is left between the side wall of the substrate 2 and the side wall of the receiving groove 10 to allow the overflowing adhesive during the mounting process to flow. The overflowing adhesive can flow along the side wall of the substrate 2 in the flow gap without directly adhering to the substrate 2 carrier, thereby reducing the frequency of cleaning the substrate 2 carrier and improving mounting efficiency.

[0033] Taking the material to be mounted 21 as a deflecting prism as an example, those skilled in the art will understand that the core function of a deflecting prism is to deflect light. If it is completely blocked by the substrate 2, the light path will be blocked, causing the optical system to fail. Therefore, during the mounting process of optical structures represented by deflecting prisms with the substrate 2, they can only be partially bonded to the substrate 2, with a portion exposed to ensure unobstructed paths for incident and outgoing light. Simultaneously, in this embodiment, when placing the material to be mounted 21, the operator can also position it using the overlapping platform 11, further improving the positional accuracy between the material to be mounted 21 and the substrate 2. The reduced bonding area of ​​the partially exposed material to be mounted 21 helps control curing force and thermal stress. Furthermore, after assembly, the operator usually needs to confirm the final position and angle of the material, and the exposed portion also provides a detection space for measuring equipment.

[0034] In this embodiment, the material to be mounted 21 is partially exposed along the length direction of the substrate 2. In some other embodiments, the material to be mounted 21 may also be partially exposed along the width direction of the substrate 2. The material to be mounted 21 may also be partially exposed along a direction that is at an angle to the length or width direction of the substrate 2. This embodiment does not limit this.

[0035] Optionally, the substrate 2 and the material to be mounted 21 have a mounting position. The mounting end 20 of the substrate 2 refers to the end of the substrate 2 near the mounting position. The mounting end 20 includes a mounting surface, an abutting surface, a first side surface, and a second side surface. The mounting surface usually refers to the upper surface of the substrate 2, that is, the material to be mounted 21 needs to be mounted on the mounting surface of the substrate 2. The abutting surface refers to the end face of the mounting end 20 of the substrate 2, and the abutting surface abuts against the receiving groove 10 along the length direction of the receiving groove 10. The first side surface and the second side surface abut against the receiving groove 10 along the width direction of the receiving groove 10, respectively.

[0036] Please refer to Figures 3-4The receiving groove 10 has an abutment end face 12, and the substrate 2 has an abutment surface along its own length. The abutment end face 12 and the abutment surface partially abut against each other. The overlapping platform 11 protrudes from the abutment end face 12 toward the substrate 2, and when the abutment end face 12 and the abutment surface partially abut against each other, a gap is left between the overlapping platform 11 and the substrate 2. Thus, the overlapping platform 11 is set at the abutment end face 12 of the receiving groove 10. After the mounting end 20 of the substrate 2 is inserted into the receiving groove 10, the position of the substrate 2 is relatively fixed after the abutment surface and the abutment end face 12 partially abut against each other. At this time, the operator can place the material to be mounted 21 in the corresponding position according to the position and size of the overlapping platform 11, so that the material to be mounted 21 is partially located on the substrate 2 and partially located on the overlapping platform 11, thereby achieving the positioning of the material to be mounted 21. At the same time, the gap between the overlapping platform 11 and the substrate 2 also provides a basis for setting the glue flow gap.

[0037] Specifically, the shape and width of the overlapping platform 11 are adapted to the shape and width of the exposed part of the material 21 to be mounted. The operator can overlap the edge of the material 21 to be mounted with the edge of the overlapping platform 11 based on the overlapping platform 11 to achieve precise positioning between the two. This can also improve the consistency of the operator's manual mounting position and help reduce the performance difference between optical modules of the same model and batch.

[0038] At the same time, operators can also form different sized marks on the surface of the overlapping platform 11 according to the size difference of the material 21 to be mounted, so as to achieve fast and accurate positioning when mounting materials of different sizes.

[0039] Furthermore, such as Figures 3-4 As shown, the abutting end face 12 has a concave section 120 and an abutting section 121 along the depth direction of the receiving groove 10. The concave section 120 is recessed inward relative to the abutting section 121 in a direction away from the substrate 2. The abutting section 121 abuts against the abutting surface, and a first adhesive flow gap is formed between the concave section 120 and the abutting surface. The gap is connected to the first adhesive flow gap to allow overflowing adhesive to flow into the first adhesive flow gap (not shown in the figure). Thus, during the process of mounting the material to be mounted 21 to the substrate 2, the operator needs to apply adhesive to the mounting surface of the substrate 2 and apply downward pressure to the material to be mounted 21. The adhesive will flow outward on the mounting surface under pressure. The adhesive flowing towards the overlapping platform 11 will flow through the gap between the overlapping platform 11 and the substrate 2, and along the abutting surface in the first adhesive flow gap, thereby preventing the adhesive from directly adhering to the substrate 2 carrier. Meanwhile, due to the viscosity of the adhesive, it will stop on the contact surface after flowing a certain distance along the contact surface, instead of flowing all the way to the bottom of the first adhesive flow gap. In addition, the contact section 121 can further enhance the fixing effect of the receiving groove 10 on the substrate 2, and prevent the substrate 2 from moving in the receiving groove 10 due to the formation of the adhesive flow gap, thus reducing the mounting accuracy.

[0040] Optionally, the dimension of the first adhesive flow gap along the depth direction of the receiving groove 10 can be adapted to the flow distance of the selected adhesive on the contact surface. When multiple adhesives are selected, the dimension of the first adhesive flow gap along the depth direction of the receiving groove 10 can be adapted to the flow distance of the most fluid adhesive on the contact surface to ensure that the adhesive does not flow all the way to the bottom of the first adhesive flow gap, thereby avoiding adhesion between the substrate 2 and the substrate 2 carrier.

[0041] Similarly, the receiving groove 10 has a first abutting side 13 and abutting side 14. The first abutting side 13 and the second abutting side 14 are located on the same side of the abutting end face 12 along the length direction, and the first abutting side 13 and the second abutting side 14 are respectively connected to the two ends of the abutting end face 12; the first side and the second side are located on the same side of the abutting surface along the length direction, and the first side and the second side are respectively connected to the two ends of the abutting surface; the first side partially abuts with the first abutting side 13, and the second side partially abuts with the second abutting side 14; the first abutting side 13 has a first outward protrusion 130 and a first connecting section 131 along the depth direction of the receiving groove 10. The protruding section 130 protrudes outward relative to the first connecting section 131 in a direction away from the substrate 2, and the first protruding section 130 is located above the first connecting section 131. The first connecting section 131 abuts against the first side surface, and a second flow gap (not shown in the figure) is formed between the first protruding section 130 and the first side surface. The second abutting side surface 14 has a second protruding section and a second connecting section along the depth direction of the receiving groove 10. The second protruding section protrudes outward relative to the second connecting section in a direction away from the substrate 2, and the second protruding section is located above the second connecting section. The second connecting section abuts against the second side surface, and a third flow gap (not shown in the figure) is formed between the second protruding section and the second side surface.

[0042] In this way, the adhesive between the substrate 2 and the material to be mounted 21 will flow outwards on the mounting surface of the substrate 2. The adhesive flowing towards both sides of the receiving groove 10 along the width direction will flow along the first and second sides in the corresponding flow gaps, thereby preventing overflowing adhesive from directly adhering to the substrate 2 and the substrate 2 carrier. At the same time, the provision of the first connecting section 131 and the second connecting section can further enhance the fixing effect of the receiving groove 10 on the substrate 2, preventing the substrate 2 from moving in the receiving groove 10 due to the formation of flow gaps, thus reducing the mounting accuracy.

[0043] Since the first protruding section 130 is located above the first connecting section 131, the second adhesive flow gap is open in the depth direction of the receiving groove 10, forming a first opening, through which the adhesive can flow directly along the first side in the second adhesive flow gap; similarly, since the second protruding section is located above the second connecting section, the third adhesive flow gap is open in the depth direction of the receiving groove 10, forming a second opening, through which the adhesive can flow directly along the second side in the third adhesive flow gap.

[0044] It should be noted that "above" mentioned above refers to the relative position along the depth direction of the receiving groove 10, that is, the maximum distance between the first protruding section 130 and the top surface of the substrate 2 is less than the maximum distance between the first connecting section 131 and the top surface of the substrate 2; the maximum distance between the second protruding section and the top surface of the substrate 2 is less than the maximum distance between the second connecting section and the top surface of the substrate 2.

[0045] exist Figure 4 In the illustrated example, substrate 2 has a mounting position where substrate 2 and the material to be mounted 21 are mounted. A second and a third adhesive flow gap are located at both ends of the mounting position along the width of the receiving groove 10. Optionally, the second and third adhesive flow gaps may be located only near the mounting position along the length of the receiving groove 10 to allow for overflowing adhesive flow. For areas where adhesive will not overflow, the side of the receiving groove 10 should abut against the side of substrate 2 to maintain the fixing effect of the receiving groove 10 on substrate 2.

[0046] As an example, the depth of the receiving groove 10 is adapted to the thickness of the substrate 2. In other embodiments, the depth of the receiving groove 10 may be slightly greater than or slightly less than the thickness of the substrate 2, but it should be noted that the top surface of the overlapping platform 11 still needs to be flush with the top surface of the substrate 2 to ensure that there is no angle difference between the material to be mounted 21 and the substrate 2 during mounting.

[0047] Please refer to Figures 1-2 as well as Figures 5-6The mounting assembly 4 includes a concave support member 40 and a pressure block 41. The concave support member 40 has two support rods 400 arranged at intervals along the width direction of the receiving groove 10. The substrate carrier 1 is provided with corresponding engaging portions 15 along the width direction of the receiving groove 10. The support rods 400 are correspondingly inserted into the engaging portions 15, and the bottom surface of the substrate carrier 2 abuts against the carrier receiving portion 30. The support rods 400 are provided with pressure block connecting portions 402, and the pressure block 41 is provided with protrusions 410, which are engaged in the pressure block connecting portions 402. Thus, the pressure block 41 and the substrate 2 carrier are both engaged with the support rod 400, which can ensure that the relative position of the pressure block 41 and the mounting position on the substrate 2 is fixed. During the mounting process, the pressure block 41 and the concave support 40 move together along the depth direction of the receiving groove 10, thereby enabling the pressure block 41 to apply downward pressure perpendicular to the mounting surface of the substrate 2 to the material to be mounted, further avoiding the possibility of the material to be mounted 21 deflecting after being subjected to force.

[0048] Specifically, in this embodiment, the substrate 2 carrier is fixedly connected to the carrier receiving portion 30 on the platform 3 by fasteners (e.g., screws), and engages with the support rod 400 by the engaging portion 15, keeping the substrate 2 carrier stationary during the mounting process. The pressure block 41 engages with the pressure block connecting portion 402 of the support rod 400 by a protrusion 410, and is fixedly connected to the support rod 400 by a ball screw. Exemplarily, the ball screw is made of a threaded housing, a spring, and a steel ball. After the threaded housing is screwed into the threaded hole of the support rod 400, the steel ball at the front end protrudes from the surface. When the pressure block 41 approaches, it compresses the steel ball, thereby compressing the spring and generating a reverse, continuous elastic force. Through the steel ball acting on the pressure block 41, the ball screw can achieve precise positioning, elastic locking, and eliminate the gap between the pressure block 41 and the support rod 400. In this way, the pressure block 41 will not loosen during the movement of the concave support member 40, ensuring the safety and practicality of the fixture.

[0049] Please continue to refer to this. Figures 1-2The mounting assembly 4 also includes a first locking slider 76, a second locking slider 77, a locking slider drive 78, and a locking panel 79. The first locking slider 76 and the second locking slider 77 are respectively mounted on the locking panel 79 via the locking slider drive 78. Specifically, the locking slider drive 78 passes through the locking panel 79, and the first locking slider 76 and the second locking slider 77 are located on the side of the locking panel 79 closer to the substrate 2. An operator can drive the first locking slider 76 and the second locking slider 77 to move in a direction closer to or away from the substrate 2 by rotating the locking slider drive 78. The first locking slider 76 and the second locking slider 77 are used to abut against the substrate 2 to further lock the relative position of the substrate 2. As an example, the locking slider drive 78 can be a hand-tightening screw, the first locking slider 76 can be a sloped locking slider, and the second locking slider 77 can be a long strip locking slider. In some other embodiments, the locking slider can also be an arc-shaped locking slider or other irregularly shaped sliders. Those skilled in the art can select a suitable shape of locking slider according to the shape of the substrate 2 and the receiving groove 10 and the direction of the required locking force. This embodiment does not limit this.

[0050] Please continue to refer to this. Figures 1-2 as well as Figures 5-6 The motion component 5 includes a drive rod 50, a transmission link 51, and a top post 52. The transmission link 51 is oscillatingly arranged along the depth direction of the receiving groove 10. One end of the drive rod 50 abuts against one end of the transmission link 51, and the other end of the transmission link 51 is connected to one end of the top post 52. The other end of the top post 52 abuts against the bottom of the concave support member 40. The drive rod 50 drives the transmission link 51 to oscillate along the depth direction of the receiving groove 10, so as to drive the concave support member 40 and the pressure block 41 to move along the depth direction of the receiving groove 10 through the top post 52. In this embodiment, the drive rod 50 is a micrometer screw. In this way, the operator can achieve fine control of the displacement of the concave support member 40 and the pressure block 41 by adjusting the drive rod 50, ensuring the accuracy of each displacement. At the same time, the drive rod 50 can achieve slow and gradual displacement, avoiding the situation where the pressure block 41 moves quickly towards the material to be mounted 21, resulting in excessive downward pressure and damage to the material to be mounted 21. Alternatively, the contact surface between the aforementioned transmission link 51 and the top post 52 is an inclined surface to ensure that the drive rod 50 will not get stuck when driven, and that the top post 52 moves smoothly along the depth direction.

[0051] Exemplary, such as Figures 1-2As shown, the motion assembly 5 also includes a base 70, a first baffle 71, a second baffle 72, and a locking member 73. The base 70 supports the platform 3. The first baffle 71 and the second baffle 72 are respectively disposed at both ends of the base 70 along the width direction and protrude from the top surface of the base 70 along the depth direction. The first baffle 71 has a through hole, and the locking member 73 passes through the through hole and can move towards or away from the platform 3. After the platform 3 is placed on the top surface of the base 70, the operator can drive the locking member 73 to move towards the platform 3, so that the locking member 73 abuts against the platform 3 until the other side wall of the platform 3 abuts against the second baffle 72, thereby fixing the relative position of the platform 3. Specifically, the locking member 73 can be a locking screw.

[0052] Furthermore, the aforementioned concave support member 40 also includes a connecting rod 401, which extends along the width direction of the receiving groove 10 and is connected to the ends of the two support rods 400 respectively. The base 70 and the platform 3 have a first connecting hole and a second connecting hole for coaxial connection, and the top column 52 passes through the first connecting hole and the second connecting hole in sequence, and abuts against the connecting rod 401 of the concave support member 40.

[0053] Specifically, the motion component 5 also includes a fixed baffle 74 and a connecting rod fastener 75. The drive rod 50 is integrally set with the fixed baffle 74. The fixed baffle 74 is installed on the base 70. At the same time, the transmission connecting rod 51 is installed on the base 70 through the connecting rod fastener 75. The transmission connecting rod 51 can swing along the depth direction of the receiving groove 10 with the connecting rod fastener 75 as the rotation axis, thereby realizing transmission.

[0054] In an optional embodiment, the pressure block 41 is provided with a pressing member 411, the pressing member 411 being adapted to the size of the material to be applied 21; the drive rod 50 has a loading / unloading position and an application position; when the drive rod 50 is in the loading / unloading position, the pressing member 411 is spaced apart from the material to be applied 21; when the drive rod 50 is in the application position, the pressing member 411 abuts against the material to be applied 21. Thus, the pressing member 411 on the pressure block 41 is adapted to the size of the material to be applied 21, allowing the operator to gradually move the pressing member 411 closer to the material to be applied 21 by adjusting the drive rod 50. During the downward pressure applied by the pressing member 411 to the material to be applied 21, pressure is applied to the entire material to be applied 21, maintaining uniform adhesive thickness. Furthermore, by adjusting the displacement of the drive rod 50, the thickness of the cured adhesive can be further controlled. Optionally, the pressing member 411 can be a glass block.

[0055] As an example, when the drive rod 50 is in the loading / unloading position, the operator drives the drive rod 50 to press down the transmission link 51 along the depth direction. The other end of the transmission link 51 swings upward along the depth direction and drives the top column 52 to move upward. The top column 52 abuts against the concave support member 40, thereby driving the concave support member 40 and the pressure block 41 to move upward. The pressing member 411 moves away from the material to be mounted 21. At this time, the operator can load and unload the substrate 2 and the material to be mounted 21.

[0056] When the drive rod 50 is in the mounting position, the operator drives the drive rod 50 to move upward along the depth direction. At this time, the drive rod 50 releases the downward pressure on the transmission link 51, causing the transmission link 51 to swing upward. The other end of the transmission link 51 swings downward, driving the top post 52 to move downward. The top post 52 releases its contact with the concave support 40. The concave support 40 and the pressure block 41 move downward. The pressure member 411 moves toward the material to be mounted 21 and finally comes into contact with the material to be mounted 21 to provide downward pressure to the material to be mounted 21.

[0057] For the best options, please continue to refer to them. Figure 2 and Figure 6 An elastic element 6 is also provided between the substrate 2 carrier and the concave support 40. The elastic element 6 is extendable and retractable along the depth direction of the receiving groove 10. Thus, as the drive rod 50 moves from the loading / unloading position to the mounting position, the concave support 40 and the pressure block 41 continuously move downward. After the pressing member 411 on the pressure block 41 contacts the material to be mounted 21, the kinetic energy of the concave support 40 and the pressure block 41 moving downward is absorbed by the elastic element 6, which can prevent the concave support 40 and the pressure block 41 from falling continuously. At the same time, it can also keep the downward pressure of the pressing member 411 on the material to be mounted 21 within a stable range, avoiding damage to the material to be mounted 21 due to excessive downward pressure.

[0058] In this embodiment, the elastic element 6 is mounted on the elastic element mounting block 60. The elastic element mounting block 60 abuts against the top surface of the connecting rod 401 of the concave support rod 400. Specifically, the abutment structure can be positioned by steel balls. The top surface of the connecting rod 401 can be provided with a semi-circular recess. The bottom surface of the elastic element mounting block 60 is provided with steel balls, which are located in the semi-circular recess. The elastic element 6 is mounted on the surface of the elastic element mounting block 60 away from the steel balls. The surface of the substrate 2 carrier away from the receiving groove 10 abuts against the elastic element 6. Thus, after the pressing member 411 on the pressure block 41 comes into contact with the material 21 to be mounted, the force is transmitted to the elastic element 6 through the substrate 2 carrier. The elastic element 6 is compressed along the depth direction and forms a reaction force to maintain a stable downward pressure.

[0059] As an alternative embodiment, the optical structure mounting fixture provided in this application embodiment can use the following mounting method when performing mounting operations.

[0060] The operator moves the drive lever 50 to the loading / unloading position, places the substrate 2 in the receiving groove 10 of the substrate 2 carrier, and fixes the substrate 2 with the first locking slider 76 and the second locking slider 77. Adhesive is applied to the mounting end 20 of the substrate 2, and the material to be mounted 21 is placed in the corresponding position based on the position and size of the overlapping platform 11. At this time, the operator moves the drive lever 50 from the loading / unloading position to the mounting position. The transmission link 51 and the top column 52 drive the concave support 40 and the pressure block 41 to move towards the material to be mounted 21 until the pressing member 411 on the pressure block 41 abuts against the material to be mounted 21 and remains stably pressed down under the action of the elastic member 6. During the pressing process, the adhesive flows outwards on the mounting surface of the substrate 2, and can flow along the contact surface, the first side surface and the second side surface in the corresponding adhesive flow gaps. After the adhesive has cured, the operator moves the drive rod 50 from the mounting position to the loading and unloading position. After the mounted material and substrate 2 are unloaded, the above operation is repeated.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
