[0002] With the rapid development of multimedia technology, electronic products with recording capabilities, such as digital cameras, camcorders, and smartphones, are becoming increasingly popular among consumers. The lenses of these electronic products are also trending towards thinner, smaller, and higher pixel counts. As ordinary single-lens cameras are increasingly unable to meet consumers' demands for higher image quality, array lenses for miniaturized electronic devices have emerged.

[0003] Existing methods for assembling array lenses are inconvenient due to the large number of lenses, making precise assembly of the lens elements and quick assembly / disassembly of the lens barrel difficult. Therefore, they do not meet current requirements. To address this, we propose a high-precision assembly method for array lenses. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision assembled array lens to solve the problems mentioned in the background art, such as the inconvenience of precise assembly of lenses and quick disassembly and assembly of lens barrels when assembling array lenses due to the large number of lenses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision assembled array lens, comprising a support plate, wherein mounting holes are provided at the four corners of the upper surface of the support plate, and multiple light-transmitting holes are provided in the middle of the upper surface of the mounting holes. A positioning groove is provided in the middle of the lower surface of the support plate, and a plate-shaped lens barrel is installed inside the positioning groove. Multiple lens mounting holes are provided inside the plate-shaped lens barrel, and a first plastic lens and a second plastic lens are installed inside each lens mounting hole. The second plastic lens is located on the upper surface of the first plastic lens, and the first plastic lens and the second plastic lens are coaxial.

[0006] Preferably, the upper end face of the plate-shaped lens barrel is in close contact with the inner wall of the positioning groove, the plurality of lens mounting holes and light transmission holes are provided in a one-to-one correspondence, the lens mounting holes and light transmission holes are connected through each other, and the plurality of lens mounting holes and light transmission holes are arranged in an array.

[0007] Preferably, the first plastic lens and the second plastic lens are locked and installed to the plate-shaped lens barrel via a bracket plate, and both the first plastic lens and the second plastic lens are convex lenses.

[0008] Preferably, the lower end face of the support plate is provided with sliding grooves on both sides of the positioning groove, and a pressing unit is installed on the inner side of each of the two sliding grooves. The two pressing units are installed symmetrically with respect to the positioning groove. Each pressing unit includes a transmission seat, and multiple pressure plates are fixedly installed on the lower end face of the transmission seat. A guide post is fixedly installed on one end of the transmission seat, and a support spring is provided on the other end of the transmission seat. Multiple positioning strips are provided on both sides of the plate-shaped lens barrel.

[0009] Preferably, the transmission seat, guide post, and multiple pressure plates are integrally injection molded, the plate-shaped lens barrel and multiple positioning strips are integrally injection molded, one end of the transmission seat is slidably connected to the support plate through the guide post, the cross-section of the guide post is polygonal, the other end of the transmission seat is connected to the support plate through a support spring, and the multiple positioning strips and pressure plates are all linearly arranged, with the spacing between two adjacent positioning strips and pressure plates being consistent.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model places multiple first plastic lenses and second plastic lenses sequentially inside the lens mounting holes, so that the first plastic lenses are positioned on the lower end face of the second plastic lenses and are coaxial with the second plastic lenses. Then, the lens mounting holes are inserted into the inner side of the positioning groove and in contact with the support plate. At this time, the support plate and the plate-shaped lens barrel facilitate the synchronous pressing of the arrayed first plastic lenses and second plastic lenses, effectively reducing the installation difficulty of the first plastic lenses and second plastic lenses and improving the installation accuracy. By positioning and synchronously installing the lenses of the array lens, the assembly difficulty of the lens is reduced.

[0012] 2. This utility model utilizes multiple pressure plates and positioning strips for the installation of the plate-shaped lens barrel. Under the elastic support of the support spring, the pressure plates and positioning strips are stably connected. Furthermore, the two transmission seats automatically limit and press the plate-shaped lens barrel through the multiple pressure plates and positioning strips, improving the installation efficiency of the plate-shaped lens barrel. When disassembling the plate-shaped lens barrel, the transmission seats slide axially on the inner side of the slide groove. The cross-section of the guide post is polygonal, allowing the transmission seats to drive the pressure plates to slide and separate from the positioning strips through the guide post. At this time, the support spring is in a compressed state, which facilitates the separation of the support plate from the plate-shaped lens barrel. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 This utility model provides an embodiment of a high-precision assembled array lens, including a support plate 1. Mounting holes 101 are provided at the four corners of the upper surface of the support plate 1. Multiple light-transmitting holes 103 are provided in the middle of the upper surface of the mounting holes 101. A positioning groove 102 is provided in the middle of the lower surface of the support plate 1. A plate-shaped lens barrel 2 is installed inside the positioning groove 102. The upper surface of the plate-shaped lens barrel 2 is in close contact with the inner wall of the positioning groove 102. Multiple lens mounting holes 201 are provided inside the plate-shaped lens barrel 2. The multiple lens mounting holes 201 and light-transmitting holes 103 are arranged in an array, and the lens mounting holes 201 and light-transmitting holes 103 are connected through each other. The positioning groove 102 facilitates the positioning of the plate-shaped lens barrel 2.

[0021] Each lens mounting hole 201 has a first plastic lens 3 and a second plastic lens 4 installed inside. The second plastic lens 4 is located on the upper end face of the first plastic lens 3. The first plastic lens 3 and the second plastic lens 4 are coaxial. The first plastic lens 3 and the second plastic lens 4 are locked to the plate-shaped lens barrel 2 through the bracket plate 1. The first plastic lens 3 and the second plastic lens 4 are both convex lenses. The lens mounting holes 201 facilitate the array installation of the first plastic lens 3 and the second plastic lens 4.

[0022] Please see Figure 4 and Figure 5The lower end face of the support plate 1 is provided with sliding grooves 104 on both sides of the positioning groove 102. Pressing units 5 are installed on the inner side of the two sliding grooves 104. The two pressing units 5 are symmetrically installed with respect to the positioning groove 102. The pressing unit 5 includes a transmission seat 501. Multiple pressing plates 502 are fixedly installed on the lower end face of the transmission seat 501. A guide post 504 is fixedly installed on one end of the transmission seat 501. One end of the transmission seat 501 is slidably connected to the support plate 1 through the guide post 504. The cross-section of the guide post 504 is polygonal. The guide post 504 linearly guides the transmission seat 501 to prevent the transmission seat 501 from driving the pressing plates 502 to deflect, thus maintaining the stability of the plate-shaped lens barrel 2.

[0023] The other end of the transmission seat 501 is connected to the support plate 1 through the support spring 503. The transmission seat 501, the guide post 504 and the multiple pressure plates 502 are integrally injection molded. The other end of the transmission seat 501 is provided with the support spring 503. Multiple positioning strips 202 are provided on both sides of the plate-shaped lens barrel 2. The plate-shaped lens barrel 2 and the multiple positioning strips 202 are integrally injection molded. The multiple positioning strips 202 and the pressure plates 502 are arranged linearly. The spacing between two adjacent positioning strips 202 and pressure plates 502 is consistent. Under the elastic support of the support spring 503, the pressure plates 502 and the positioning strips 202 are kept stably connected. Thus, the two transmission seats 501 realize the automatic limiting and pressing operation of the plate-shaped lens barrel 2 through the multiple pressure plates 502 and the positioning strips 202.

[0024] In summary, when installing the lens, multiple lens mounting holes 201 are provided on the upper end face of the plate-shaped lens barrel 2, so that multiple first plastic lenses 3 and second plastic lenses 4 are placed in sequence inside the lens mounting holes 201, so that the first plastic lenses 3 are located on the lower end face of the second plastic lenses 4 and are coaxial with the second plastic lenses 4, and then the lens mounting holes 201 are inserted into the inner side of the positioning groove 102 and in contact with the bracket plate 1.

[0025] At this time, the bracket plate 1 and the plate-shaped lens barrel 2 facilitate the synchronous pressing of the first plastic lens 3 and the second plastic lens 4 arranged in an array, effectively reducing the installation difficulty of the first plastic lens 3 and the second plastic lens 4 and improving the installation accuracy. Multiple positioning strips 202 are fixed on both sides of the plate-shaped lens barrel 2, so that multiple pressure plates 502 are snapped into the positioning strips 202 during the installation process. The transmission seat 501 is connected to the bracket plate 1 through the support spring 503. Under the elastic support of the support spring 503, the pressure plates 502 and the positioning strips 202 are kept stably connected. Thus, the two transmission seats 501 realize the automatic limiting and pressing operation of the plate-shaped lens barrel 2 through multiple pressure plates 502 and positioning strips 202, improving the installation efficiency of the plate-shaped lens barrel 2.

[0026] Furthermore, when disassembling the plate-shaped lens barrel 2, the transmission seat 501 is axially slid on the inner side of the slide groove 104. The cross-section of the guide post 504 is polygonal, so that the transmission seat 501 drives the pressure plate 502 to slide through the guide post 504 and separate from the positioning strip 202. At this time, the support spring 503 is in a compressed state, which facilitates the separation of the support plate 1 from the plate-shaped lens barrel 2.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
