Abstract
Description
Technical Field
[0001] This invention relates to the field of optical lens module manufacturing technology, and in particular to an automatic locking mechanism for optical lens modules. Background Technology
[0002] The optical lens module is mainly composed of an optical lens and a lens mount. The two are usually connected by a threaded connection. The assembly process relies on an automatic locking mechanism to drive the lens to rotate relative to the lens mount to complete the screw-locking. The assembly quality is controlled by parameters such as torque, angle, and drive descent stroke.
[0003] In the existing automated assembly process of optical lens modules, only one independent automatic locking mechanism is usually configured at an assembly station to perform the forward screwing-in locking operation of the lens. When assembly defects such as misaligned threads or incomplete screwing occur, an additional locking device is required to perform reverse unlocking of the lens in order to disassemble the defective assembly.
[0004] However, two independent automatic locking mechanisms cannot guarantee that the clamping position, clamping force, coaxiality and other clamping states are consistent with the forward locking process. During the reverse unlocking rotation, uneven force on the lens is easily caused, which can lead to problems such as lens barrel deformation, thread stripping, and lens edge chipping. It may even damage the optical lens module assembly and affect the yield rate. Summary of the Invention
[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an automatic locking mechanism for an optical lens module. By setting up two sets of identical automatic locking mechanisms at two different points in an assembly station, and the gripping parts of the two sets of automatic locking mechanisms can be detached and assembled with each other independently, so that during unlocking, only the gripping part of the forward locking point needs to be transferred to the automatic locking mechanism at the reverse unlocking point for assembly.
[0006] An automatic locking mechanism for an optical lens module according to an embodiment of the present invention includes a turntable, a frame, a material transfer assembly, and a support base. The turntable rotates along a central axis and has two centrally symmetrically arranged through-areas. A suspension mounting assembly is provided next to each of the through-areas. Each suspension mounting assembly has a locking part and a clamping part movably disposed thereon. The frame has two sets of lifting assemblies that correspond one-to-one with the two through-areas. A first drive assembly is provided on each lifting assembly. The material transfer assembly has a... The lifting unit is horizontally reciprocating, with one end of the reciprocating path located below the turntable and the other end extending to the mirror mount loading station. The lifting unit can also be vertically raised and lowered to pass through the through area. The support base is movably positioned and supported on the lifting unit to support and position the mirror mount. When the through area is vertically aligned with the lifting assembly, the lifting unit can lock into the locking part after rising vertically to a preset height. The first driving assembly can be driven to the clamping part to drive the clamping part to perform a combined rotational and vertical movement.
[0007] Furthermore, the suspension mounting assembly includes a cantilever, a lead screw, and a three-jaw cylinder. The cantilever is fixed on the turntable, the lead screw is rotatably mounted on the cantilever, the upper end of the lead screw can form a blind engagement with the first drive assembly, and the three-jaw cylinder is connected to the lower end of the lead screw.
[0008] Furthermore, the first drive assembly includes a rotary driver, the rotary driver is provided with a spline shaft, the upper end of the lead screw is provided with a blind hole internal spline that mates with the spline shaft, and the depth of the blind hole internal spline is not less than the locking stroke between the lens and the lens mount.
[0009] Furthermore, the cantilever is provided with a limiting hole and a second driving component. A locking block is slidably disposed in the limiting hole. The lifting part is provided with a locking hole that cooperates with the locking block. The second driving component is connected to the locking block in a transmission manner to drive the locking block to extend out of the limiting hole and to drive the locking block to retract into the limiting hole.
[0010] Furthermore, the second drive assembly includes a first telescopic member, the fixed end of which is disposed on the cantilever, and the telescopic end of which is connected to the locking block.
[0011] Furthermore, the lifting assembly includes a fixed plate and a second telescopic member. The fixed plate is fixed on the frame, the fixed end of the second telescopic member is disposed on the fixed plate, and the telescopic end of the second telescopic member is connected to the first drive assembly.
[0012] Furthermore, a linear sliding pair is also formed between the first driving component and the fixed plate.
[0013] Furthermore, the material conveying assembly includes a first linear motor and a third telescopic device, with the fixed end of the third telescopic device located on the moving platform of the first linear motor.
[0014] Furthermore, the telescopic end of the third telescopic device is provided with a support plate, the support plate is provided with a plug hole, and the support base is provided with a sliding column that can be slidably inserted into the plug hole.
[0015] Furthermore, the frame includes a frame plate, a crossbeam, and a second linear motor. The frame plate is disposed on the crossbeam, the second linear motor is disposed on the frame plate, and the lifting assembly is disposed on the moving platform of the second linear motor.
[0016] The automatic locking mechanism for optical lens modules according to embodiments of the present invention has at least the following beneficial effects: This application, by symmetrically arranging two sets of suspension mounting components with locking and clamping parts on a turntable, and utilizing the rotation of the turntable to switch work positions, allows the forward locking process of the lens and the reverse unlocking process of defective products to share the same clamping part for operation. This effectively ensures a high degree of consistency between the two processes in core clamping states such as clamping position, clamping force, and coaxiality. During the locking and unlocking operations, the precise alignment and cooperation between the lifting part of the material transfer component, the through area of the turntable, and the lifting component, combined with the locking mechanism of the lifting part and the locking part, ensures high consistency between the two processes in core clamping states such as clamping position, clamping force, and coaxiality. The positioning structure enables high-precision positioning and reliable fixation of the lens mount, lens, and their assembly. Simultaneously, through the transmission cooperation between the first drive component and the clamping part, the clamping part can complete a compound motion of rotation and vertical movement. Compared with the existing technology that requires two independent locking devices for forward locking and reverse unlocking, this structure reduces the potential risks of assembly deviation and uneven force caused by inconsistent clamping states of the two devices. To a certain extent, it can avoid secondary damage problems such as thread stripping, lens barrel deformation, and lens edge chipping during lens disassembly, thereby improving the stability of lens module locking and unlocking operations.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.
[0023] Reference Figures 1 to 7 The present invention provides an automatic locking mechanism for an optical lens module, comprising a turntable 100, a frame 200, a material transfer assembly 300, and a support base 400.
[0024] The turntable 100 is horizontally rotatable and located at the bottom of the frame 200. The rotation axis of the turntable 100 is a vertical axis, allowing it to rotate precisely 360 degrees around this axis. The turntable 100 has two identical through-sections 110, arranged symmetrically about the vertical axis of the turntable 100, with an included angle of 180 degrees between their centers. These two through-sections 110 respectively form the locking and unlocking workstations, and the precise rotation of the turntable 100 enables rapid switching between the two workstations.
[0025] A set of suspension mounting components 120 is fixedly installed on each side of each through area 110 of the turntable 100. The two sets of suspension mounting components 120 have completely identical structures, dimensions, and installation parameters, and are symmetrically arranged above the turntable 100. They rotate synchronously with the turntable 100 to achieve synchronous switching of workstations. Specifically, each set of suspension mounting components 120 is provided with a locking part and a clamping part is movably provided. The clamping part is located above the locking part. When the turntable 100 is stationary, the clamping part can perform a compound motion of vertical lifting and circumferential rotation relative to the turntable 100, that is, rotating and lifting at the same time. In this way, the clamping part can drive the lens to synchronously complete the compound motion of rotation and vertical feed to adapt to the movement trajectory of lens thread engagement and thread unengagement.
[0026] It should be noted that the parameters of the two clamping parts should be as uniform as possible, including core parameters such as clamping stroke, clamping force, rotational coaxiality, and vertical movement stroke, so that the clamping state of the forward locking station and the reverse unlocking station is as consistent as possible.
[0027] Two sets of identical lifting components 140 are symmetrically arranged above the turntable 100 on the frame 200. During operation, the two sets of lifting components 140 and the two through areas 110 can be precisely aligned up and down to meet the operation requirements of the locking and unlocking stations respectively.
[0028] The moving end of the lifting assembly 140 is equipped with a first drive assembly 210, which can move vertically in sync with the lifting assembly 140. During operation, the first drive assembly 210 can output two types of rotation torque: forward and reverse. Forward rotation is matched for lens engagement and locking operations, while reverse rotation is matched for defective product unlocking and disassembly operations.
[0029] The material conveying assembly 300 is equipped with a lifting unit, which can achieve precise reciprocating movement in the horizontal direction. One end of the lifting unit is located below the turntable 100, and the other end extends to the mirror mounting station outside the turntable 100. During operation, the lifting unit can move directly below the through area 110 and pass through the through area 110 to achieve lifting movement. It is understood that the size of the through area 110 is larger than the maximum outer diameter of the material lifting unit, so that the through area 110 can reserve a reasonable clearance to ensure that the lifting unit can pass smoothly during vertical lifting.
[0030] The support base 400 is movably positioned and supported on the top end face of the lifting unit. The support base 400 is a customized positioning fixture adapted to the shape of the mirror mount. Its upper end face has a positioning groove that precisely matches the bottom of the mirror mount. A limiting stop 420 is provided inside the positioning groove to achieve precise positioning of the mirror mount, thereby limiting horizontal offset and circumferential rotation during operation. Understandably, because the support base 400 is movably positioned, matching support bases 400 can be quickly replaced according to different specifications of mirror mounts, thus improving the versatility of the equipment.
[0031] During operation, once the lifting unit rises vertically to the preset height, the locking part locks with the lifting unit to limit its horizontal offset and circumferential rotation, thereby fixing the lens mount in place and preventing assembly deviations caused by offset or shaking during operation. Then, in conjunction with the vertical lifting motion of the lifting assembly 140, the first drive assembly 210 establishes a transmission connection with the clamping part, driving the clamping part to synchronously complete the combined rotation and vertical feed motion of the optical lens, thus adapting to the movement trajectory of the lens thread engagement and disengagement.
[0032] In some optional embodiments, the through region 110 can be configured as a through groove structure of circular, rectangular or other shapes, and the through region 110 can be set at the edge of the turntable 100 or near the edge of the turntable 100.
[0033] In some optional embodiments, the turntable 100 can be a precision cam dividing turntable 100 that is mature in the field of automation equipment. There is no need to develop an additional main drive structure for the turntable 100. Its working principle is as follows: the servo motor drives the input shaft of the cam divider to rotate continuously. Through the meshing transmission between the cam surface and the indexing roller, the continuous rotational motion of the input shaft is converted into the intermittent indexing motion of the output shaft. The output shaft drives the upper turntable 100 plate to rotate synchronously and intermittently. Moreover, the cam divider has a self-locking characteristic. After the turntable 100 completes the angle switching, it can remain rigidly locked. In this way, no autonomous movement will occur during the operation, thereby ensuring the stability of the work position.
[0034] Reference Figure 1 In some optional embodiments, the material transfer assembly 300 can be set on the machine base 130 of the precision cam dividing turntable 100, and the frame 200 can also be set on the machine base 130 of the precision cam dividing turntable 100. Of course, the frame 200 can also be set in the work area where the machine base 130 is located.
[0035] In some optional embodiments, the frame 200 can be integrally formed from high-strength cast iron or aluminum alloy profiles, giving it high rigidity, high flatness, and resistance to deformation. This effectively avoids equipment vibration and displacement deviation caused by long-term, high-frequency operation, ensuring the overall machine's operational accuracy.
[0036] Reference Figure 6 In some alternative embodiments, the suspension mounting assembly 120 includes a cantilever 121, a lead screw 122, and a three-jaw cylinder 123.
[0037] The cantilever 121 can be rigidly fixed to the upper end face of the turntable 100 by fasteners and rotates synchronously with the turntable 100. The lead screw 122 is mounted on the cantilever 121 in a circumferentially rotatable manner. The lead screw 122 is arranged in the vertical direction. The upper end of the lead screw 122 and the first drive assembly 210 can form a blind connection for torque transmission. The blind connection has radial and angular adaptive fault tolerance capabilities and can achieve automatic alignment and mating under working conditions with slight alignment deviations.
[0038] The three-jaw cylinder 123, as a functional component that directly performs lens clamping, is fixedly installed at the lower end of the lead screw 122. The three-jaw cylinder 123 is connected to the pneumatic control circuit of the equipment. The control system can accurately control the clamping force of the clamping jaws by independently adjusting the air intake pressure to adapt to optical lenses with different outer diameters and wall thicknesses.
[0039] For example, the three-jaw cylinder 123 has three sets of clamping jaws evenly distributed in the circumference. Each clamping jaw has an anti-static flexible clamping pad that can be detachably installed on its inner side. The flexible clamping pad is made of polyurethane or silicone, which can increase the static friction between the pad and the outer wall of the optical lens barrel, and at the same time reduce the scratches and deformation caused by the rigid clamping directly squeezing the lens barrel.
[0040] Reference Figure 6 In some optional embodiments, a nut seat 124 can be provided on the cantilever 121. When the lead screw 122 rotates circumferentially, the lead screw 122 can move vertically by means of the helical transmission pair between the lead screw 122 and the nut seat 124.
[0041] In this embodiment, after the turntable 100 rotates to the position and completes the workstation switch, the material transfer component 300 lifts the support base 400 carrying the lens mount into position and locks it in place with the locking part. Then, the lifting component 140 drives the first drive component 210 to move vertically downward. After the first drive component 210 completes the blind engagement with the upper end of the lead screw 122, the first drive component 210 starts to output rotational power, so that the three-jaw cylinder 123 drives the clamped optical lens to synchronously complete the composite motion of rotation and vertical movement, realizing the forward screwing and locking of the lens.
[0042] When processing the reverse unlocking process of defective assemblies, the first drive component 210 outputs torque in the reverse direction, driving the three-jaw cylinder 123 to rotate the lens in the reverse direction to unlock the teeth.
[0043] When it is necessary to switch workstations, the control lifting component 140 drives the first drive component 210 to rise, thereby disengaging the torque transmission between the first drive component 210 and the lead screw 122.
[0044] Reference Figure 7 In some optional embodiments, the first drive assembly 210 includes a rotary driver, and the power output end of the rotary driver is provided with a spline shaft 211 with an external spline structure. Correspondingly, a blind hole internal spline 125 is provided on the end face of the upper end of the lead screw 122, and the spline shaft 211 and the blind hole internal spline 125 form a pluggable and self-aligning blind spline connection structure.
[0045] Both the spline shaft 211 and the blind hole spline 125 adopt an involute spline structure. With the inherent good guiding and radial adaptive fault tolerance of the involute spline structure, when the lifting assembly 140 drives the first driving assembly 210 to descend vertically, the spline shaft 211 can automatically align and self-align by relying on the tooth surface chamfer, thus smoothly inserting into the blind hole spline 125 at the upper end of the lead screw 122, achieving blind insertion without structural interference. After the docking is completed, the spline tooth surfaces are fully engaged and circumferentially limited, which can stably transmit the positive locking torque and the reverse unlocking torque.
[0046] Meanwhile, the axial depth of the inner spline 125 in the blind hole is set to be no less than the complete locking stroke of the optical lens and the lens mount. In this way, axial relative sliding compensation can be achieved between the spline shaft 211 and the inner spline. During the entire process of vertical feeding of the lens, the spline meshing is always effective, so as to achieve uninterrupted power transmission.
[0047] As a preferred implementation, the rotary drive uses a servo motor. The servo motor has the characteristics of controllable torque, closed-loop angle, adjustable speed, and precise forward and reverse switching, which can be well adapted to the high-precision locking and unlocking operation of optical lenses.
[0048] Reference Figure 6 In some optional embodiments, the cantilever 121 is provided with a limiting hole 1211 and a second drive assembly 1212. The limiting hole 1211 can be a horizontal, straight through hole or a blind hole, and a locking block 1213 is slidably fitted inside the limiting hole 1211. The locking block 1213 can perform linear telescopic movement along the channel of the limiting hole 1211. A matching locking hole 321 is provided on the lifting part corresponding to the telescopic path of the locking block 1213, and the locking hole 321 and the locking block 1213 can achieve a plug-in locking engagement.
[0049] The second drive assembly 1212 is fixedly installed on the cantilever 121 and forms a stable transmission connection with the locking block 1213. The second drive assembly 1212 is used to output linear drive force to drive the locking block 1213 to extend outward from the inside of the limiting hole 1211 and insert and fix it into the locking hole 321 of the support base 400 to achieve rigid locking. At the same time, the second drive assembly 1212 can also drive the locking block 1213 to retract in the opposite direction until the locking limit on the support base 400 is released.
[0050] It is understandable that when the lock block 1213 retracts, it can be partially or completely retracted into the lock hole 321.
[0051] It should be noted that the limiting hole 1211 can be formed using a precision boring process. This results in low wall roughness and high straightness accuracy, providing a full-range sliding guide constraint for the locking block 1213, limiting its radial wobble and angular deviation, and ensuring smooth, jam-free, and deviation-free extension and retraction. Furthermore, the clearance fit between the diameter of the limiting hole 1211 and the outer diameter of the locking block 1213, with tolerances controlled within a precise sliding clearance range, satisfies the free extension and retraction requirements of the locking block 1213 while maximally suppressing radial runout during operation, thus ensuring locking fit accuracy.
[0052] Reference Figure 6In some optional embodiments, the second drive assembly 1212 includes a first telescopic member, which provides a stable and controllable linear driving force for the telescopic movement of the locking block 1213. During assembly, the fixed end of the first telescopic member is fixedly mounted to a preset installation position on the cantilever 121, and the telescopic end of the first telescopic member forms a rigid transmission connection structure with the tail of the locking block 1213.
[0053] As a preferred embodiment, the first telescopic device employs a precision pneumatic telescopic cylinder. Of course, in other alternative embodiments, the first telescopic device can also be an electric telescopic push rod, an electromagnetic telescopic device, or other linear telescopic drive components, all of which can achieve controllable linear telescopic drive function. These are conventional equivalent alternatives in the art and all fall within the protection scope of this invention.
[0054] Reference Figure 3 In some optional embodiments, the lifting assembly 140 is used to realize the overall vertical lifting displacement of the first drive assembly 210, so as to complete the automatic alignment blind connection, transmission fit and automatic disengagement after operation of the power structure. Its specific structure includes a fixed plate 141 and a second telescopic device 142.
[0055] The fixed plate 141 serves as the base for fixing the entire machine, and the second telescopic device 142 is the vertical lifting power actuator. The fixed plate 141 is rigidly fixedly installed in the preset installation area of the frame 200, and the fixed end of the second telescopic device 142 is fastened to the fixed plate 141. The second telescopic device 142 is arranged in the vertical direction, and the telescopic end of the second telescopic device 142 is rigidly connected to the first drive assembly 210.
[0056] During operation, the second telescopic device 142 can precisely drive the first drive assembly 210 to move up or down as a whole through its own vertical telescopic movement, realizing the docking and separation of the first drive assembly 210 and the lead screw 122, and meeting the power docking and clearance requirements of the locking and unlocking processes.
[0057] As a preferred embodiment, the second telescopic device 142 employs a precision pneumatic telescopic cylinder. Of course, in other alternative embodiments, the second telescopic device 142 can also use an electric telescopic push rod, an electromagnetic telescopic device, or other linear telescopic drive components, all of which can achieve controllable linear telescopic drive function. These are conventional equivalent alternatives in the art and all fall within the protection scope of this invention.
[0058] Reference Figure 3In some optional embodiments, a linear sliding pair is further formed between the first drive component 210 and the fixed plate 141, so that the first drive component 210 as a whole can make precise and limited linear sliding motion relative to the fixed plate 141 in the vertical direction. This can further improve the straightness, stability and coaxiality accuracy of the vertical lifting of the first drive component 210, avoid the swing that exists when relying solely on the second telescopic device 142 for driving, and ensure the docking accuracy between the first drive component 210 and the lead screw 122.
[0059] For example, when the first drive component 210 uses a motor, a slide rail can be provided on the fixed plate 141 and a slider can be provided on the motor housing, and a linear sliding pair can be formed by the slider cooperating with the slide rail.
[0060] Reference Figure 4 In some optional embodiments, the material transfer assembly 300 includes a first linear motor 310 and a third telescopic member 320. The third telescopic member 320 serves as a material lifting and lowering execution unit, and the first linear motor 310 serves as a material horizontal translation drive unit. The fixed end of the third telescopic member 320 is fixedly mounted on the moving platform of the first linear motor 310, and can synchronously complete high-precision horizontal reciprocating movement with the moving platform of the first linear motor 310. The telescopic end of the third telescopic member 320 constitutes the aforementioned lifting part, used to support the support base 400 and drive the support base 400, the lens mount, and the lens assembly to complete vertical lifting and lowering actions, thereby realizing a composite conveying motion of horizontal material transfer and vertical lifting and positioning.
[0061] As a preferred embodiment, the third telescopic device 320 employs a precision electric telescopic cylinder. Of course, in other alternative embodiments, the third telescopic device 320 may also use a pneumatic telescopic push rod, an electromagnetic telescopic device, or other linear telescopic drive components, all of which can achieve controllable linear telescopic drive function. These are conventional equivalent alternatives in the art and all fall within the protection scope of this invention.
[0062] Reference Figure 4 In some optional embodiments, a support plate 322 is fixedly mounted on the telescopic end of the third telescopic device 320. The support plate 322 serves as a load-bearing transition base to support the support seat 400. An insertion hole 3221 is provided on the plate body of the support plate 322. Correspondingly, a sliding column 410 is fixedly provided on the bottom end face of the support seat 400. The sliding column 410 and the support seat 400 are an integral or rigidly connected structure. The sliding column 410 can be slidably inserted into the insertion hole 3221 along the axial direction, so that the support seat 400 is slidably positioned and mounted on the support plate 322.
[0063] Reference Figure 2In some optional embodiments, the frame 200 includes a crossbeam 220, a frame plate 230, and a second linear motor 240. The crossbeam 220 serves as the main load-bearing beam structure on the upper part of the frame 200. The frame plate 230 is fixedly installed on the crossbeam 220. The second linear motor 240 is integrally fixedly assembled onto the surface of the frame plate 230. The lifting assembly 140 is integrally fixed onto the moving platform of the second linear motor 240.
[0064] In this embodiment, the second linear motor 240 can drive the lifting component 140 and the first drive component 210 to achieve a small and precise horizontal displacement, so that the power docking center can be adaptively fine-tuned to eliminate assembly deviations at fixed workstations.
[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
