Description

A liquid lens that prevents PAD breakage Technical Field

[0001] This utility model relates to the field of liquid lens technology, and in particular to a liquid lens that can prevent PAD point breakage. Background Technology

[0002] With the rapid development of technology, liquid lens technology has gradually attracted attention due to its unique advantages. Liquid lenses achieve focal length changes by changing the curvature of the lens formed by liquid crystals through voltage. They are characterized by small size, no moving parts, and a wide zoom range.

[0003] Liquid crystal lenses have two pads, which need to be connected to pads on the PCB via an FPC to control zoom. The connection between the FPC and the pads on the liquid crystal lens is usually made by binding with gold wire. Since the two ends of the gold wire are connected to the pads and the FPC respectively, the gold wire is easily pulled by the FPC and may fall off, thus affecting the practical application of the liquid crystal lens. To address this issue, a liquid crystal lens that can prevent the pads from breaking is proposed. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid lens that can prevent PAD breakage in response to the above-mentioned technical problems. The LDS design is carried out on a conventional lens mount so that both the FPC and the gold wire are connected to it, so that the FPC will not directly cause the problem of pulling on the gold wire.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A liquid lens that can prevent PAD breakage includes a lens mount, in which a liquid lens is embedded and assembled. The surface of the liquid lens has a PAD area, and an LDS area is provided on the surface of the lens mount at a position corresponding to the PAD area. The PAD area and the LDS area are connected by a gold wire.

[0007] In this context, an FPC is also bonded to the LDS region near the gold wire, and the gold wire enables the FPC to connect with the liquid lens.

[0008] Furthermore, the PAD region has two areas;

[0009] The LDS region includes a first sub-LDS region and a second sub-LDS region, and the two PAD regions are respectively connected to the corresponding first sub-LDS region and second sub-LDS region through corresponding gold wires.

[0010] Furthermore, there is an insulating separation region between the first sub-LDS region and the second sub-LDS region.

[0011] Furthermore, both the first sub-LDS region and the second sub-LDS region have a horizontal base plane and a vertical base plane, with the gold wire connected to the horizontal base plane and the FPC bonded to the vertical base plane.

[0012] Furthermore, the FPC also has a first binding region and a second binding region corresponding to the first sub-LDS region and the second sub-LDS region, respectively;

[0013] The first binding area and the second binding area are respectively bound to the corresponding vertical base surface.

[0014] Furthermore, the lens mount has a lens groove and an adhesive dispensing groove. After the liquid lens is embedded in the lens groove, it is fixed by the adhesive in the adhesive dispensing groove.

[0015] Furthermore, a lens is also embedded in one end of the lens mount, and a through groove is provided in the lens mount, which allows the space for accommodating the lens to communicate with the lens slot.

[0016] Furthermore, the lens, lens mount, liquid lens, and FPC are combined to form a liquid lens module;

[0017] The lens is located below the liquid lens module.

[0018] Furthermore, a base is mounted on top of the liquid lens module.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The liquid lens provided by this utility model, which can prevent PAD breakage, features an LDS area on the lens mount, where both the gold wire and FPC are connected. The LDS area allows for indirect connection with the gold wire and the liquid lens. This prevents the gold wire from being directly pulled during FPC pulling or subsequent connection and assembly, thus avoiding the problem of gold wire breakage and separation, which could affect the stability of the connection.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] As described in the background section, liquid lens has two PAD points. These PAD points need to be connected to pad points on the PCB via the FPC to control zoom. The connection between the FPC and the PAD points on the liquid lens is usually made by binding with gold wire. Since the two ends of the gold wire are connected to the PAD point and the FPC respectively, the gold wire is easily pulled by the FPC and may fall off, thus affecting the practical application of the liquid lens.

[0037] To solve this technical problem, this utility model provides a liquid lens that can prevent PAD breakage, which is applied to liquid lenses.

[0038] Specifically, please refer to Figures 1-5. The liquid lens that can prevent PAD breakage specifically includes a lens mount 2, in which a liquid lens 3 is embedded and assembled. The surface of the liquid lens 3 has a PAD area 31, and an LDS area 21 is provided on the surface of the lens mount 2 at the position corresponding to the PAD area 31. The PAD area 31 and the LDS area 21 are connected by a gold wire 22.

[0039] In particular, an FPC4 is also bound to the LDS region 21 near the gold wire 22, and the FPC4 can be connected to the liquid lens 3 by the action of the gold wire 22.

[0040] The liquid lens provided by this utility model, which can prevent PAD breakage, has an LDS region 21 designed on the lens mount 2, on which the gold wire 22 and FPC4 are connected. It can be indirectly connected to the gold wire 22 and its liquid lens 3 through the LDS region 21. In this way, during the pulling of FPC4 or subsequent connection and assembly process, the gold wire 22 is not directly involved, thereby avoiding the problem that the gold wire 22 is prone to breakage and separation, which affects the stability of the connection.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] Example 1

[0045] Please refer to Figures 1-4. A liquid lens that can prevent PAD breakage includes a lens mount 2. A liquid lens 3 is embedded in the lens mount 2. The surface of the liquid lens 3 has a PAD area 31. An LDS area 21 is provided on the surface of the lens mount 2 at a position corresponding to the PAD area 31. The PAD area 31 and the LDS area 21 are connected by a gold wire 22.

[0046] Among them, an FPC4 is also bound to the LDS region 21 near the gold wire 22, and the FPC4 can be connected to the liquid lens 3 by the action of the gold wire 22.

[0047] The LDS (Laser Direct Structuring) described in this embodiment is an advanced manufacturing technology that uses lasers to directly generate three-dimensional circuit patterns on special materials. It is primarily used in the production of components such as antennas, sensors, and precision circuits for electronic devices. The following is a detailed explanation of its core principles:

[0048] LDS technology achieves circuit formation through a two-step process: laser activation and chemical plating.

[0049] Laser engraving: This involves scanning the surface of a plastic substrate (such as LDS-specific PC / ABS) containing metal oxide additives using a specific wavelength laser (e.g., Nd:YAG laser, 1064nm). The laser energy decomposes the additives (e.g., copper-chromium oxide), exposing a micron-scale rough structure and forming catalytically active metal nuclei (e.g., copper atom clusters). The laser path is controlled by CAD design, directly "drawing" the 3D circuit pattern.

[0050] Electroless plating: Laser-treated components are immersed in an electroless plating solution (such as a solution containing copper ions), where metals (copper, nickel, gold, etc.) are selectively deposited in the laser-activated areas through an autocatalytic reaction. Areas not irradiated by the laser lack catalytic activity and are not plated with metal, thus achieving precise shaping of the circuit pattern.

[0051] This is a well-known technical concept in the art, so it is not further elaborated in this embodiment. By using LDS technology to form a corresponding LDS region 21 on the conventional lens mount 2, the positive and negative electrodes of the liquid lens 3 are connected to the LDS region 21 through gold wires 22 to achieve connection. The FPC4 is directly soldered to the LDS region 21. In this way, the FPC4 will not pull on the gold wires 22 during subsequent assembly, thus avoiding the problem of gold wires falling off and separating, improving the overall application stability of the liquid lens. Furthermore, due to the design of the LDS region 21, the FPC4 is finally connected to the PAD region 31 on the liquid lens 3 through the LDS region 21 and the gold wires 22, which satisfies the performance control of the liquid lens 3.

[0052] Example 2

[0053] The liquid lens provided in Embodiment 1 that can prevent PAD breakage is further optimized. Specifically, as shown in FIG4, the PAD region 31 has two.

[0054] In this embodiment, the two PAD regions 31 correspond to the positive and negative electrodes of the liquid lens 3, respectively. As shown in Figure 4, the liquid lens 3 also has two PAD regions at the position away from the FPC4. Therefore, a single liquid lens 3 has two positive electrodes and two negative electrodes. By connecting any one of the positive electrodes and one of the negative electrodes, its performance can be controlled. Similarly, in actual applications, one end of the gold wire 22 can be changed to be connected to the other positive and negative electrodes for connection.

[0055] The LDS region 21 includes a first sub-LDS region 210 and a second sub-LDS region 211. The two PAD regions 31 are respectively connected to the corresponding first sub-LDS region 210 and second sub-LDS region 211 through corresponding gold wires 22.

[0056] An insulating separation area 212 is provided between the first sub-LDS region 210 and the second sub-LDS region 211. Through the design of the insulating separation area 212, the first sub-LDS region 210 and the second sub-LDS region 211 can be separated. This allows the two PAD regions 31 on the liquid lens 3 to be independently connected to the corresponding first sub-LDS region 210 and the second sub-LDS region 211 via gold wires 22, avoiding mutual interference and ensuring independent wiring connection.

[0057] Example 3

[0058] The liquid lens provided in Embodiment 1 or 2 that can prevent PAD point breakage is further optimized, as shown in Figure 3. The first sub-LDS region 210 and the second sub-LDS region 211 both have a horizontal base surface 213 and a vertical base surface 214. The gold wire 22 is connected to the horizontal base surface 213, and the FPC4 is bound to the vertical base surface 214.

[0059] The FPC4 also has a first binding region 41 and a second binding region 42 corresponding to the first sub-LDS region 210 and the second sub-LDS region 211, respectively, wherein the first binding region 41 and the second binding region 42 are respectively bound and connected to the corresponding vertical base surface 214.

[0060] In this embodiment, the design of the horizontal base plane 213 and the vertical base plane 214 allows the FPC4 to be welded and bound to the vertical base plane 214 after the gold wire 22 is connected to the LDS area 21. This way, the binding points of the FPC4 and the gold wire 22 are staggered in the same plane, which not only provides more operational space for subsequent welding and binding of the FPC4, but also allows the FPC4 to be directly welded and bound to the outside without having to be bound inside the lens mount 2 and bent for lead-out, which is beneficial for better protection of the FPC4 itself.

[0061] Example 4

[0062] The liquid lens provided in Embodiment 3 that can prevent PAD breakage is further optimized. As shown in Figure 4, the lens holder 2 has a lens groove 23 and an adhesive groove 24. After the liquid lens 3 is embedded in the lens groove 23, it is fixed by the adhesive 25 in the adhesive groove 24.

[0063] One end of the lens mount 2 is also fitted with a lens 1. The lens mount 2 also has a through groove 26. The space used to accommodate the lens 1 is interconnected with the lens groove 23 by the through groove 26.

[0064] In practical applications, the lens 1 is first assembled into the lens mount 2, and then the liquid lens 3 is embedded into the lens mount 2 through the lens groove 23. Then, glue is applied into multiple glue grooves 24 to fix the liquid lens 3. After the liquid lens 3 is fixed, the two ends of the gold wire 22 are connected to the corresponding PAD area 31 and LDS area 21 respectively. Finally, the FPC4 is soldered and bound to the LDS area 21.

[0065] Example 5

[0066] The liquid lens that can prevent PAD breakage provided in Embodiment 4 is further optimized. As shown in Figure 5, the lens 1, lens mount 2, liquid lens 3 and FPC4 are combined to form a liquid lens module 5. A lens 6 is provided below the liquid lens module 5, and a base 7 is assembled above the liquid lens module 5.
