Description

Technical Field

[0001] The present invention relates to the technical field of glass etching, and particularly to a multi-layer liquid medicine tank type chemical thinning processing device for camera lenses. Background Art

[0002] With the popularization of optical devices such as smart phones, vehicle-mounted cameras, and AR / VR, camera modules face strict requirements for thinning. The thickness of traditional glass lenses is usually 0.8 - 1.5 mm, while high-end devices require thinning to 0.3 - 0.5 mm to adapt to the compact module space and reduce the overall weight. The etching thinning technology realizes material removal through chemical corrosion, and has advantages such as small surface damage, high edge accuracy, and suitability for processing complex curved surfaces, thus becoming the core process for precision optical lens thinning.

[0003] In the etching thinning process of glass lenses, the glass lenses after the pretreatment process are usually loaded in an orderly manner into the limiting mechanism of the etching carrier, and the etching solution is uniformly applied to the lens surface by using the spray etching technology. However, the lenses are in a static fixed state in the etching carrier, resulting in the flow of the etching solution on the fixed lens surface showing laminar flow characteristics, forming a stable boundary layer near the lens surface. Within this boundary layer, the etching ions need to reach the glass surface by diffusing through the liquid film. Due to the low diffusion mass transfer rate, the etching rate is limited. Summary of the Invention

[0004] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a multi-layer liquid medicine tank type chemical thinning processing device for camera lenses, which can effectively solve the problem in the prior art that the lenses are in a static fixed state in the etching carrier, resulting in the flow of the etching solution on the fixed lens surface showing laminar flow characteristics, forming a stable boundary layer near the lens surface. Within this boundary layer, the etching ions need to reach the glass surface by diffusing through the liquid film. Due to the low diffusion mass transfer rate, the etching rate is limited.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a multi-layer liquid medicine tank type chemical thinning processing device for camera lenses, including: A base; A casing provided on the top of the base, and a spray pipe communicating with an external storage device is fixedly installed on the inner wall of the casing. The base is rotationally installed with a carrier frame through a fixing frame provided on its top. An adjusting member is provided in the carrier frame, and multiple groups of the adjusting members are arranged in an array along the center of the carrier frame. A limiting member for fixing the lens is provided in the adjusting member; Among them, a drive unit is provided on the outer side of the casing. When the drive unit drives the carrier frame to rotate to a vertical state, the adjusting member is activated to cause the limiting member and the lens to deflect, so as to realize the uniform replacement of the etching solution contact area on the lens surface.

[0006] Further, the adjusting member includes a sliding frame, and the sliding frame is slidably connected to the outer surface of the carrier frame through a sliding sleeve arranged inside it. There are two sliding frames and they are symmetrically distributed along the center of the carrier frame. The sliding frame is rotatably connected to a U-shaped frame through a rotating shaft arranged inside it, and a torsion spring is sleeved on the outer surface of the rotating shaft.

[0007] Further, the sliding frame is slidably connected to a counterweight block through a guiding groove arranged on the outer side, and the bottom of the counterweight block is designed with an inclined surface. A spherical block that fits with the inclined surface of the counterweight block is fixedly connected to the outer side of the U-shaped frame; Among them, when the sliding frame is in a vertical state, the counterweight block slides downward along the guiding groove under the action of its own gravity, and the inclined surface of the counterweight block presses the spherical block, forcing the U-shaped frame to deflect around the axis of the rotating shaft.

[0008] Further, the limiting member includes a limiting frame fixedly connected inside the U-shaped frame. A plurality of slot holes are formed inside the limiting frame, and these slot holes are arranged in a circular array along the center of the limiting frame. The slot holes include movable holes and through holes, and the movable holes and the through holes are alternately distributed.

[0009] Further, a movable rod is rotatably connected to the movable hole through a pin shaft arranged inside it. A torsion spring is sleeved on the outer surface of the pin shaft, and there are two torsion springs and they are symmetrically distributed along the center of the pin shaft. The end of the movable rod is rotatably connected to a limiting arc plate, and there are two limiting arc plates and they are symmetrically distributed along the center of the movable rod. The limiting arc plate fits with the outer surface of the lens through a notch formed inside it. An abutting arc plate is fixedly connected to the outer surface of the movable rod, and there are two abutting arc plates and they are symmetrically distributed along the center of the movable rod.

[0010] Further, a support rod is slidably connected to the through hole through an elastic member arranged on the outer side of the through hole. A support arc plate is fixedly connected to the side of the support rod close to the lens, and the side of the support rod away from the support arc plate is designed with an arc surface.

[0011] Further, the limiting member further includes a ring frame rotatably connected inside the limiting frame. A limiting arc block that fits with the outer surface of the abutting arc plate is fixedly connected to the inner wall of the ring frame. An abutting arc block that fits with the arc surface of the support rod is fixedly connected to the inner wall of the ring frame. A driving member capable of driving the ring frame to rotate is arranged on the outer side of the limiting frame.

[0012] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: The present invention is provided with an adjusting member and a limiting member. By driving the unit, the carrier frame is rotated to a vertical state, triggering the adjusting member to drive the lens to deflect. When the carrier frame is rotated to the vertical state, the counterweight in the adjusting member slides down due to gravity, squeezing the spherical block to deflect the U-shaped frame around the rotating shaft, driving the lens to swing. When the lens swings, different regions are sequentially exposed under the liquid curtain, promoting the dynamic contact between different regions of the lens surface and the etching solution, realizing the uniform replacement of the etching solution contact region, breaking the static boundary layer, improving the diffusion mass transfer efficiency of etching ions, accelerating the etching rate, and the gravity drives the limiting frame to deflect, realizing the regular swing of the lens. When the sliding frame is in the vertical state, the counterweight slides down along the guiding groove, and its inclined surface squeezes the spherical block. When the squeezing force exceeds the torque threshold of the torsion spring, the U-shaped frame and the limiting frame drive the lens to deflect. When the position of the counterweight is switched, the squeezing forces on both sides act on the torsion spring alternately. Through the coupling of mechanical force and gravity, a regular disturbance is formed, so that the limiting frame and the lens generate reciprocating swings, avoiding the formation of laminar flow of the etching solution in a local area and improving the etching uniformity.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Embodiment:

[0019] Please refer to Figures 1-8 , the present invention provides a technical solution: a multi-layer chemical thinning processing device for camera lens in a liquid medicine tank, comprising: Base 1; A casing 2 provided on the top of the base 1, and a spray pipe 3 communicating with an external storage device is fixedly installed on the inner wall of the casing 2. The base 1 is rotatably installed with a carrier frame 4 through a fixing frame provided on its top. An adjusting member 5 is provided in the carrier frame 4, and a plurality of groups of the adjusting members 5 are provided and are distributed in an array along the center of the carrier frame 4. A limiting member 6 for fixing the lens is provided in the adjusting member 5; Among them, a driving unit is provided on the outer side of the casing 2. When the driving unit drives the carrier frame 4 to rotate to a vertical state, the adjusting member 5 is activated to cause the limiting member 6 and the lens to deflect, so as to realize the uniform replacement of the etching liquid contact area on the lens surface.

[0020] The adjusting member 5 includes a sliding frame 51. The sliding frame 51 is slidably connected to the outer surface of the carrier frame 4 through a sliding sleeve provided inside it. Two sliding frames 51 are provided and are symmetrically distributed along the center of the carrier frame 4. The sliding frame 51 is rotatably connected to a U-shaped frame 53 through a rotating shaft 52 provided inside it, and a torsion spring 54 is sleeved on the outer surface of the rotating shaft 52.

[0021] The sliding frame 51 is slidably connected with a counterweight 55 through a guiding groove arranged on the outside, and the bottom of the counterweight 55 is designed as an inclined plane. A spherical block 56 which is attached to the inclined plane of the counterweight 55 is fixedly connected to the outside of the U-shaped frame 53; When the sliding frame 51 is in a vertical state, the counterweight 55 slides downward along the guiding groove under the action of its own gravity. The inclined plane of the counterweight 55 presses the spherical block 56, forcing the U-shaped frame 53 to deflect around the axis of the rotating shaft 52.

[0022] The limiting member 6 includes a limiting frame 61 fixedly connected inside the U-shaped frame 53. A slot hole 62 is formed inside the limiting frame 61, and multiple groups of the slot holes 62 are provided and are distributed in a circumferential array along the center of the limiting frame 61. The slot hole 62 includes a movable hole and a through hole, and the movable hole and the through hole are distributed alternately.

[0023] The movable hole is rotatably connected with a movable rod 64 through a pin shaft 63 arranged inside it. A torsion spring 631 is sleeved on the outer surface of the pin shaft 63, and two of the torsion springs 631 are provided and are symmetrically distributed along the center of the pin shaft 63. The end of the movable rod 64 is rotatably connected with a limiting arc plate 641, and two of the limiting arc plates 641 are provided and are symmetrically distributed along the center of the movable rod 64. The limiting arc plate 641 is attached to the outer surface of the lens through a notch formed inside it. An abutting arc plate 642 is fixedly connected to the outer surface of the movable rod 64, and two of the abutting arc plates 642 are provided and are symmetrically distributed along the center of the movable rod 64.

[0024] The through hole is slidably connected with a support rod 65 through an elastic member arranged on its outside. A support arc plate 651 is fixedly connected to the side of the support rod 65 close to the lens, and the side of the support rod 65 away from the support arc plate 651 is designed as an arc surface.

[0025] The limiting member 6 further includes a ring frame 66 rotatably connected inside the limiting frame 61. A limiting arc block 661 which is attached to the outer surface of the abutting arc plate 642 is fixedly connected to the inner wall of the ring frame 66. Abutting arc blocks 662 which are attached to the arc surface of the support rod 65 are fixedly connected to the inner wall of the ring frame 66. A driving member for driving the ring frame 66 to rotate is arranged on the outside of the limiting frame 61.

[0026] The usage principle and advantages of this multi-layer liquid medicine tank type camera lens chemical thinning treatment equipment: Lens installation process: During the operation of the equipment, an operator can open the observation window on the top of the machine shell 2 and disassemble the carrier frame 4 from the fixed frame. Subsequently, the camera lens to be processed is placed inside the limiting frame 61. At this time, the driving member outside the limiting frame 61 drives the ring frame 66 to generate a rotational movement around its central axis. The driving member can adopt a gear and gear ring transmission, and the surfaces of related components are treated with corrosion resistance to avoid damage to them when the etching liquid is sprayed, affecting the normal use of the limiting member 6.

[0027] As the ring frame 66 rotates, the inner limiting arc block 661 contacts the abutting arc plate 642 on the outer surface of the movable rod 64. The driver drives the ring frame 66 to rotate, converting its circular motion into radial displacement of the limiting arc block 661, creating a pushing load on the abutting arc plate 642. When the load exceeds the critical torque of the torsion spring 631, the movable rod 64 undergoes angular displacement about the central axis of the pin 63, driving the abutting arc plate 642 toward the lens until the inner notch of the abutting arc plate 642 fully aligns with the outer surface of the lens. Multiple abutting arc plates 642, evenly distributed around the circumference, form multi-point contact constraints on the lens from different directions, achieving high-precision positioning and fixation of the lens within the limiting frame 61. Three to six groups of abutting arc plates 642 can be used, with four groups selected here.

[0028] After the lenses are secured, the spacing is adjusted using the adjustment mechanism on the sleeve. Here, the adjustment mechanism preferably comprises a slotted, elongated hole and a bolt. The operator rotates the bolts on the outer periphery of the sleeve to disengage the bolt ends from the surface of the carrier frame 4, releasing the mechanical stop between the sleeve and the support mechanism. At this point, the spacing between adjacent stoppers 6 can be precisely adjusted along the central axis of the carrier frame 4, using the graduated markings on the carrier frame 4. Once adjusted, the bolts are tightened in the opposite direction, ensuring a close fit between the curved, concave surface of the bolt ends and the carrier surface, securing the stoppers 6 securely through frictional torque.

[0029] Etching thinning process: After the lens positioning process is complete, the operator reassembles the carrier 4 into the fixed frame. The drive unit and carrier 4 are dynamically coupled via a quick-release connection mechanism, such as a spring-loaded thimble coupling. Once the carrier 4 is installed, the observation window on the top of the housing 2 is closed. The drive unit then drives the carrier 4 to rotate at a constant speed around its geometric axis, consistent with the etching process parameters. Simultaneously, the spray pipes 3 on both sides of the housing 2 evenly spray the etching solution from the external etching solution storage device onto the lens processing area.

[0030] It is worth noting that a conical liquid collecting tank is provided on the top of the base 1. When the atomizing spray device sprays the external etching liquid evenly onto the surface of the lens, the excess etching liquid generates a directional flow under the action of the gravity field and drips downward through the surface of the workpiece. The collecting tank forms a convergence effect on the etching liquid through its conical contraction geometry, thereby realizing efficient collection of the fluid. The collecting tank can form a communicating vessel structure with the external recovery system through the piping system, ensuring that the etching waste liquid is directional transmitted under the drive of the pressure difference, avoiding the accumulation of liquid in the closed processing cavity surrounded by the base 1 and the equipment housing, and effectively preventing the electrochemical corrosion of the metal structure, moving parts and electrical components of the base 1 by highly corrosive liquids, thereby extending the service life of the equipment. At the same time, it reduces the moisture retention inside the cavity, reduces the local temperature and humidity field distortion caused by liquid volatilization, ensures the stability of the etching process, and improves the workpiece processing yield.

[0031] During the uniform rotation of the vehicle rack 4, the driving member outside the limiting frame 61 drives the ring frame 66 to perform a reverse rotational movement. When the ring frame 66 rotates in the reverse direction, the normal pressure between the limiting arc block 661 and the abutting arc plate 642 gradually decreases. Under the action of the restoring moment of the torsion spring 631 on the outer surface of the pin shaft 63, the pin shaft 63 drives the movable rod 64 to gradually reset, so that the limiting arc plate 641 attached to the outer surface of the lens gradually disengages from the lens. At the same time, during the rotation of the ring frame 66, the abutting arc block 662 makes progressive contact with the arc surface of the support rod 65, and forces the support rod 65 to move along the through hole towards the lens direction through the geometric constraint of the arc surface. When the limiting arc plate 641 of the ring frame 66 has just completed the disengagement action from the lens, the contact extrusion between the abutting arc block 662 and the arc surface of the support rod 65 reaches the peak state. At this time, the support rod 65 drives the support arc plate 651 to accurately fit the outer surface of the lens, forming a dynamic support structure for the lens, effectively preventing the lens from falling out of the limiting frame 61. With the continuous rotation of the ring frame 66, the limiting arc block 661 makes contact with another abutting arc plate 642 on the movable rod 64, thereby driving the limiting arc plate 641 to gradually approach the lens direction until it completely fits the outer surface of the lens. During this process, the extrusion load between the abutting arc block 662 and the support rod 65 gradually decays. Under the synergistic action of the elastic member, the support rod 65 drives the support arc plate 651 to complete the reset action. When the other limiting arc plate 641 completes the positioning constraint on the lens, the switching of the limiting positions of the two groups of limiting arc plates 641 on the lens is realized, effectively avoiding the continuous constraint of the limiting arc plate 641 on the same area of the lens, avoiding the deviation of the etching thinning uniformity caused by local shielding, and ensuring the etching processing quality of the lens.

[0032] Lens deflection process: During the process of the driving unit driving the carrier frame 4 to rotate at a constant speed, when the carrier frame 4 drives the adjusting member 5 to rotate to the vertical state, the counterweight 55 outside the sliding frame 51 moves downward along the guiding chute under the action of its own gravity. During this process, the inclined surface at the bottom of the counterweight 55 comes into contact with and presses against the spherical block 56 outside the U-shaped frame 53. When the extrusion force between the inclined surface of the counterweight 55 and the spherical convex block exceeds the maximum torque threshold of the torsion spring 54 installed on the outer surface of the circumference of the rotating shaft 52, it will force the U-shaped frame 53 to drive the limiting frame 61 to deflect along the axis of the rotating shaft 52 itself. Since the two U-shaped frames 53 are symmetrically designed, the counterweight 55 on the surface of the lower sliding frame 51 will move to the bottom of the guiding chute under the action of its own gravity. At this time, the counterweight 55 is no longer in contact with the spherical block 56 on the same side. As the two counterweights 55 continuously switch positions during the movement, the swinging action of the limiting frame 61 and the fixed lens inside it can be realized. Moreover, the two counterweights, 55 are symmetrically distributed along the central axis of the limiting frame 61. The symmetrically distributed U-shaped frames 53 and counterweights 55 enable the extrusion forces on both sides to act on the torsion spring alternately when the positions of the counterweights 55 are switched, thereby realizing the reciprocating swing of the limiting block. The design of the counterweights 55 with central symmetry ensures that the overall center of mass of the mechanism is always on the central axis during the swinging process, avoiding the generation of additional eccentric torque and ensuring the smoothness and reliability of the swinging action. Through the synergistic action of gravity and mechanical force, the regular swinging of the limiting block and the lens assembly inside it is realized, meeting the usage requirements under specific working conditions.

[0033] The present invention adopts the adjusting member 5 and the limiting member 6, which have the following advantages: Advantage 1: The replacement of the dynamic etching liquid contact area improves the mass transfer efficiency. By driving the carrier frame 4 to rotate to the vertical state through the driving unit, it triggers the adjusting member 5 to drive the lens to deflect. When the carrier frame 4 rotates to the vertical state, the counterweight 55 in the adjusting member 5 slides down due to gravity, squeezing the spherical block 56 to cause the U-shaped frame 53 to deflect around the rotating shaft 52, driving the lens to swing. When the lens swings, different regions are successively exposed under the liquid curtain, prompting different regions on the lens surface to come into dynamic contact with the etching liquid, realizing the uniform replacement of the etching liquid contact area, breaking the static boundary layer, improving the diffusion mass transfer efficiency of etching ions, and accelerating the etching rate.

[0034] Advantage 2: Gravity drives the limiting frame 61 to deflect, realizing the regular swinging of the lens. When the sliding frame 51 is in the vertical state, the counterweight 55 slides down along the guiding groove, and its inclined surface squeezes the spherical block 56. When the extrusion force exceeds the torque threshold of the torsion spring 54, the U-shaped frame 53 and the limiting frame 61 drive the lens to deflect. When the position of the counterweight 55 is switched, the extrusion forces on both sides act on the torsion spring 54 alternately. Through the coupling of mechanical force and gravity, a regular disturbance is formed, so that the limiting frame 61 and the lens generate reciprocating swings, avoiding the formation of laminar flow of the etching liquid in a local area and improving the etching uniformity.

[0035] Advantage 3: The driving member drives the ring frame 66 to rotate. The limiting arc block 661 pushes against the abutting arc plate 642, causing the movable rod 64 to rotate around the pin shaft 63. The limiting arc plate 641 fits against the outer surface of the lens. The circumferentially evenly distributed abutting arc plates 642 and the limiting arc plate 641 form a multi-point contact constraint, achieving high-precision positioning of the lens, avoiding displacement deviation during the processing, and by rotating the ring frame 66 in different directions, it is possible to achieve the alternating contact of the limiting arc plate 641 and the supporting arc plate 651 with the lens, dynamically switching the limiting points, avoiding continuous occlusion in a single area, and ensuring the uniformity of etching and thinning.

[0036] Advantage 4: When the ring frame 66 rotates forward, the limiting arc block 661 pushes against the abutting arc plate 642, causing the limiting arc plate 641 to fit and fix the lens. When rotating in the reverse direction, the torsion spring 631 resets the limiting arc plate 641. At the same time, the abutting arc block 662 squeezes the support rod 65, causing the supporting arc plate 651 to dynamically support the lens. When the ring frame 66 rotates, the abutting arc block 662 squeezes the arc surface of the support rod 65, overcoming the resistance of the elastic member to make the supporting arc plate 651 fit against the lens. When the limiting arc plate 641 disengages, the supporting arc plate 651 synchronously provides a supporting force, realizing seamless connection between limiting and supporting.

[0037] Advantage 5: The symmetric counterweight blocks 55 slide down alternately under the action of gravity, and the generated torques cancel each other out. The torsion spring 54 at the rotating shaft 52 provides a restoring force, so that the center of mass does not shift when the limiting frame 61 swings. By means of mechanical balance design, the vibration of the equipment is reduced, ensuring the stability of the etching process. The two counterweight blocks 55 are symmetrically distributed along the center of the carrier frame 4. During the swinging process, the overall center of mass remains on the axis, avoiding eccentric torques and ensuring smooth movement.

[0038] Advantage 6: Through the positioning scale on the outer surface of the carrier frame 4, the use spacing between adjacent limiters 6 can be adjusted, ensuring that the distance between each lens unit remains constant during the etching process, avoiding the problem that the distance error between adjacent components exceeds the limit caused by the change of the lens thickness parameter, thus avoiding the influence of uneven distribution of the etching ion concentration field on the etching rate uniformity. Combined with the rotational movement of the carrier frame 4, it can more effectively disturb and destroy the boundary layer flow field structure, thereby improving the overall etching process efficiency.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
