Abstract
Description
Technical Field
[0001] This utility model belongs to the field of assembly mold technology, specifically relating to an assembly mold for an optical lens module. Background Technology
[0002] An assembly mold for an optical lens module is a device specifically designed for the precise assembly of optical lens components. Because optical lenses require extremely high precision and stability, these assembly molds require special attention in their design and manufacturing to ensure that the optical components can be assembled accurately and efficiently.
[0003] Existing optical lens module assembly molds suffer from insufficient calibration and positioning accuracy and poor anti-offset performance during actual use. The need for repeated calibration and the susceptibility to offset make the assembly process cumbersome and time-consuming, significantly reducing production efficiency and increasing the assembly error rate, thus negatively impacting product quality. Utility Model Content
[0004] The purpose of this utility model is to provide an assembly mold for optical lens modules to solve the problems of inaccurate positioning and easy displacement of optical lens module assembly molds mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly mold for an optical lens module, comprising: an operating table, a first template disposed above the operating table, a connecting plate fixed between the first template and the operating table, a second template disposed above the first template, a telescopic component installed between the second template and the operating table, a circuit board assembled inside the first template, a lens module body assembled inside the second template, positioning plates disposed at the bottom of both the first and second templates, positioning rods mounted on the upper surfaces of both positioning plates, mounting components disposed between the positioning plates and the first template and between the positioning plates and the second template, movable components disposed on the sidewalls of both the first and second templates, and through holes corresponding to the screw holes of the lens module body and the circuit board pre-drilled on the first and second templates.
[0006] Preferably, the mounting assembly includes a mounting block, a first hollow cylinder, a movable block, and a first spring. The lower end faces of the first template and the second template are provided with mounting grooves. The mounting block is fixed to the upper end face of the positioning plate and is adapted to the mounting groove. The first hollow cylinder is fixed to the side wall of the mounting block. A first movable cylinder is provided on one side of the first hollow cylinder, and a portion of the first movable cylinder is located inside the first hollow cylinder. The movable block is installed at the end of the first movable cylinder located outside the first hollow cylinder. The first spring connects the first hollow cylinder and the first movable cylinder. The movable block is hemispherical.
[0007] The movable component includes a through groove and a movable rod. The through groove is formed on the side walls of the first template and the second template, and the through groove is connected to the mounting groove. The movable rod passes through the through groove.
[0008] The telescopic assembly includes a support plate and an electric telescopic rod. The support plate is installed on the side wall of the second template, and the electric telescopic rod is installed on the upper surface of the operating table. The output end of the electric telescopic rod is connected to the support plate.
[0009] Through the above technical solution:
[0010] During use, before installing the circuit board and lens module, first align the positioning rod with the through holes on the first and second templates, align the mounting block and mounting groove, and press the positioning plate towards the side closest to the template. At this time, the mounting block on the positioning plate will gradually enter the mounting groove on the lower end face of the first and second templates. After the mounting block enters the mounting groove, the first spring pushes the first movable cylinder and the movable block with its elastic force, causing the movable block to move outward along the first movable cylinder. The movable block will eventually enter the through groove and contact the side wall of the through groove, thereby achieving a snap-fit on the positioning plate. Through this snap-fit, the positioning plate is fixed between the first and second templates, ensuring that it will not shift during subsequent assembly.
[0011] In the initial stage of mold assembly, the positioning rods need to pass through the through holes on the first and second templates respectively, and align with the screw holes on the circuit board. Only when the screw holes on the circuit board, the through holes on the first template, the lens module mounting position, and the through holes on the second template are completely aligned can the subsequent screws pass through smoothly and achieve accurate connection. The positioning rods effectively prevent the templates from shifting or misaligning before assembly, providing a reliable guarantee for subsequent assembly processes.
[0012] When disassembly or adjustment is required, the operator needs to press the movable rod on the side wall of the first and second templates. Pressing the movable rod will abut the spherical movable block, causing it to move inward. The movement of the movable block will cause the first movable cylinder to retract into the first hollow cylinder. This will release the locking state between the positioning plate and the first and second templates. After the locking is released, the positioning plate can be easily removed, facilitating subsequent disassembly or adjustment operations.
[0013] During assembly, the electric telescopic rod is activated, which moves the second template closer to the first template, allowing the lens module body to initially align with the circuit board. During this process, the positioning rod and positioning plate ensure the positioning of each component, laying the foundation for subsequent assembly and ensuring a tight fit with the circuit board to prevent any displacement or loosening. Finally, the lens module body and circuit board are securely connected by bolts, completing the entire assembly process.
[0014] The upper end face of the second template is rotatably connected to a support column. A fixing plate is installed at the top of the support column. A second hollow cylinder is installed on the lower end face of the fixing plate away from the support column. A second movable cylinder is provided below the second hollow cylinder, and a portion of the second movable cylinder is located inside the second hollow cylinder. A second spring is connected between the second hollow cylinder and the second movable cylinder. A pressure plate is installed at the bottom of the second movable cylinder. An anti-detachment component is provided between the second hollow cylinder and the second movable cylinder. The second template and the support column can be rotatably connected through bearings.
[0015] Preferably, the anti-detachment component includes an anti-detachment plate and an anti-detachment block. The anti-detachment plate is installed on the outer wall of the second movable cylinder, and the anti-detachment block is installed on the inner wall of the second hollow cylinder. The anti-detachment block blocks the movement path of the anti-detachment plate, ensuring that the second hollow cylinder and the second movable cylinder are not easily detached.
[0016] Through the above technical solution:
[0017] During use, after installing the lens module body and the second template, the operator needs to pull the second movable cylinder upwards. Simultaneously, the support column needs to be rotated. Rotating the support column changes the position of the pressure plate, moving it above the lens module body. Once the pressure plate is above the lens module body, the operator can release the pulling force on the second movable cylinder. At this point, the second spring begins to function. Due to the spring's elasticity, the second movable cylinder moves downwards, causing the pressure plate to apply downward pressure. Under the spring force, the pressure plate presses the lens module body down, ensuring that the lens module body will not loosen or shift during subsequent assembly.
[0018] Since the support column is fixed and does not have a telescopic function, a reaction force is generated on the support column when the pressure plate applies pressure downward. This reaction force makes it difficult for the support column to continue to rotate after the pressure plate is pressed. This design ensures that the pressure plate can maintain a stable position after pressure is applied and will not lose the clamping force on the lens module due to accidental rotation.
[0019] After the pressure plate clamps the lens module, the second template begins to move downwards, bringing the lens module closer to the circuit board. As the second template descends, the lens module gradually fits tightly against the circuit board. Due to the clamping force of the pressure plate, the lens module will not move upwards during the descent, ensuring alignment with the circuit board. Since the pressure plate applies downward pressure to the lens module throughout the bolt assembly process, this continuous clamping force ensures that the lens module will not move upwards or shift during assembly, providing a basis for accurate bolt assembly.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] (1) This utility model ensures complete alignment of the circuit board, lens module body, and template through hole by setting up components such as a positioning plate, positioning rod, and movable rod. During use, first align the positioning rod with the template through hole, then press the positioning plate to allow the mounting block to slide into the mounting groove. At this time, the spring pushes the movable block into the through groove, thereby fixing the positioning plate. The positioning rod achieves precise alignment of the circuit board, lens module body, and template through hole, facilitating screw assembly. When disassembly or adjustment is required, press the movable rod to move the movable block, thereby releasing the lock on the positioning plate and facilitating subsequent operations.
[0022] (2) This utility model achieves stable bolt assembly by setting up a support column, a second spring, and a pressure plate. In use, the second movable cylinder is moved upward and the support column is rotated to place the pressure plate above the lens module body; after being released, the second spring pushes the pressure plate to press the lens module body to prevent it from loosening. Through the continuous pressure of the pressure plate, the lens module body can fit tightly against the circuit board, and finally achieve stable bolt assembly. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-5 As shown, this utility model provides the following technical solution: an assembly mold for an optical lens module, comprising: an operating table 1, a first template 2 disposed above the operating table 1, a connecting plate 3 fixed between the first template 2 and the operating table 1, a second template 4 disposed above the first template 2, a telescopic component installed between the second template 4 and the operating table 1, a circuit board 5 assembled inside the first template 2, a lens module body 6 assembled inside the second template 4, a positioning plate 7 disposed at the bottom of both the first template 2 and the second template 4, a positioning rod 8 installed on the upper surface of both the positioning plate 7, an installation component disposed between the positioning plate 7 and the first template 2 and between the positioning plate 7 and the second template 4, movable components disposed on the side walls of both the first template 2 and the second template 4, and through holes corresponding to the screw holes of the lens module body 6 and the circuit board 5 pre-drilled on the first template 2 and the second template 4.
[0032] Furthermore, the mounting assembly includes a mounting block 10, a first hollow cylinder 12, a movable block 14, and a first spring 15. The lower end faces of the first template 2 and the second template 4 are provided with mounting grooves 9. The mounting block 10 is fixed to the upper end face of the positioning plate 7, and the mounting block 10 is adapted to the mounting groove 9. The first hollow cylinder 12 is fixed to the side wall of the mounting block 10. A first movable cylinder 13 is provided on one side of the first hollow cylinder 12, and a portion of the first movable cylinder 13 is located inside the first hollow cylinder 12. The movable block 14 is installed at the end of the first movable cylinder 13 located outside the first hollow cylinder 12. The first spring 15 is connected between the first hollow cylinder 12 and the first movable cylinder 13. The movable block 14 is hemispherical.
[0033] The movable component includes a through groove 11 and a movable rod 16. The through groove 11 is formed on the side wall of the first template 2 and the second template 4, and the through groove 11 is connected to the mounting groove 9. The movable rod 16 passes through the through groove 11.
[0034] The telescopic assembly includes a support plate 25 and an electric telescopic rod 26. The support plate 25 is installed on the side wall of the second template 4, and the electric telescopic rod 26 is installed on the upper surface of the operating table 1. The output end of the electric telescopic rod 26 is connected to the support plate 25.
[0035] Through the above technical solution:
[0036] In use, before installing the circuit board 5 and lens module body 6, first align the positioning rod 8 with the through holes on the first template 2 and the second template 4, align the mounting block 10 and the mounting groove 9, and press the positioning plate 7 towards the side closest to the template. At this time, the mounting block 10 on the positioning plate 7 will gradually enter the mounting groove 9 on the lower end face of the first template 2 and the second template 4. After the mounting block 10 enters the mounting groove 9, the first spring 15 pushes the first movable cylinder 13 and the movable block 14 with its elastic force, causing the movable block 14 to move outward along the first movable cylinder 13. The movable block 14 will eventually enter the through groove 11 and form contact with the side wall of the through groove 11, thereby achieving the snap-fit of the positioning plate 7. Through the snap-fit, the positioning plate 7 is fixed between the first template 2 and the second template 4, ensuring that it will not be displaced during subsequent assembly.
[0037] In the initial stage of mold assembly, the positioning rod 8 needs to pass through the through holes on the first template 2 and the second template 4 respectively, and align with the screw holes on the circuit board 5. Only when the screw holes on the circuit board 5, the through holes on the first template 2, the mounting position of the lens module body 6, and the through holes on the second template 4 are completely aligned can the subsequent screws pass through smoothly and achieve accurate connection. The positioning rod 8 effectively prevents the templates from shifting or misaligning before assembly, providing a reliable guarantee for subsequent assembly processes.
[0038] When disassembly or adjustment is required, the operator needs to press the movable rod 16 on the side wall of the first template 2 and the second template 4. Pressing the movable rod 16 will abut the spherical movable block 14, causing it to move inward. The movement of the movable block 14 will cause the first movable cylinder 13 to retract into the first hollow cylinder 12. This will release the locking state between the positioning plate 7 and the first template 2 and the second template 4. After the locking is released, the positioning plate 7 can be easily removed, which is convenient for subsequent disassembly or adjustment operations.
[0039] During assembly, the electric telescopic rod 26 is activated, which moves the second template 4 closer to the first template 2, allowing the lens module body 6 to initially align with the circuit board 5. During this process, the positioning rod 8 and positioning plate 7 ensure the positioning of each component, laying the foundation for subsequent assembly and ensuring a tight fit with the circuit board 5 to prevent any displacement or loosening. Finally, the lens module body 6 and the circuit board 5 are securely connected by bolts, completing the entire assembly process.
[0040] Please see Figures 1-6As shown, a support column 17 is rotatably connected to the upper end face of the second template 4. A fixing plate 18 is installed at the top of the support column 17. A second hollow cylinder 19 is installed on the lower end face of the fixing plate 18 away from the support column 17. A second movable cylinder 20 is provided below the second hollow cylinder 19, and a portion of the second movable cylinder 20 is located inside the second hollow cylinder 19. A second spring 21 is connected between the second hollow cylinder 19 and the second movable cylinder 20. A pressure plate 22 is installed at the bottom end of the second movable cylinder 20. An anti-detachment component is provided between the second hollow cylinder 19 and the second movable cylinder 20. The second template 4 and the support column 17 can be rotatably connected through bearings.
[0041] Furthermore, the anti-detachment component includes an anti-detachment plate 23 and an anti-detachment block 24. The anti-detachment plate 23 is installed on the outer wall of the second movable cylinder 20, and the anti-detachment block 24 is installed on the inner wall of the second hollow cylinder 19. The anti-detachment block 24 blocks the movement path of the anti-detachment plate 23, ensuring that the second hollow cylinder 19 and the second movable cylinder 20 are not easily detached.
[0042] Through the above technical solution:
[0043] In use, after installing the lens module body 6 and the second template 4, the operator needs to pull the second movable cylinder 20 upwards. Simultaneously, the support column 17 needs to be rotated. Rotating the support column 17 changes the position of the pressure plate 22, moving it above the lens module body 6. Once the pressure plate 22 is above the lens module body 6, the operator can release the pulling force on the second movable cylinder 20. At this point, the second spring 21 begins to function. Due to the spring's elasticity, the second movable cylinder 20 moves downwards, causing the pressure plate 22 to apply downward pressure. Under the spring force, the pressure plate 22 presses down firmly onto the lens module body 6. This pressure ensures that the lens module body 6 will not loosen or shift during subsequent assembly.
[0044] Since the support column 17 is fixed and does not have a telescopic function, a reaction force will be generated on the support column 17 during the process of the pressure plate 22 applying pressure downward. This reaction force will make it difficult for the support column 17 to continue to rotate after the pressure plate 22 is pressed. This design ensures that the pressure plate 22 can maintain a stable position after pressure is applied and will not lose the clamping force on the lens module body 6 due to accidental rotation.
[0045] After the pressure plate 22 presses the lens module body 6, the second template 4 begins to move downward, bringing the lens module body 6 closer to the circuit board 5. As the second template 4 descends, the lens module body 6 gradually fits tightly against the circuit board 5. Due to the clamping force of the pressure plate 22, the lens module body 6 will not move upward during the descent, ensuring alignment with the circuit board 5. Since the pressure plate 22 always applies downward pressure to the lens module body 6 during the bolt assembly process, this continuous clamping force ensures that the lens module body 6 will not move upward or be displaced during the assembly process, providing a basis for accurate bolt assembly.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
