Detailed Implementation

[0033] 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.

[0034] refer to Figure 1 The lens focusing system in this embodiment may include a test bracket 100, on which a fixture base plate 110 is provided. The lens focusing system may also include a lens positioning carrier 200, a focusing optical repeater 300, a backlight plate 400, an image acquisition device 500, and a UV irradiation device 600. The lens positioning carrier 200, the focusing optical repeater 300, the image acquisition device 500, and the UV irradiation device 600 are all disposed on the fixture base plate 110, the backlight plate 400 is disposed on the test bracket 100, and there is a gap between the backlight plate 400 and the fixture base plate 110.

[0035] refer to Figure 2 The lens focusing system in this embodiment can be used to focus the lens product 10. The lens product 10 may include a lens circuit board 11 and a lens module 12 connected to the lens circuit board 11. There may be one or two lens modules 12. When there are two lens modules 12, the two lens modules 12 may be spaced apart along the extension direction of the lens circuit board 11. The lens module 12 may include a lens bracket 121 and a lens 122, wherein the lens bracket 121 may be fixed to the lens circuit board 11, and the lens 122 may be fixed to the lens bracket 121.

[0036] The lens circuit board 11 is also provided with a first connection port 111 corresponding to each lens module 12. Specifically, when there is one lens module 12, there is one first connection port 111. When there are two lens modules 12, there are two first connection ports 111.

[0037] It is worth noting that before focusing, the lens 122 and lens bracket 121 are not fully fixed together. After focusing, the lens 122 and lens bracket 121 can be fixed together by applying adhesive. Furthermore, the different models of lens products 10 mentioned in this embodiment can be understood as having different focal lengths of the lenses 122, or different numbers of lenses 122 (one or two). Therefore, when the number of lenses 122 is the same but the focal lengths are different, the lens circuit board 11 of this type of lens product 10 is universal. For lens products 10 with dual lenses 122, the lens circuit board 11 connected to different models of lens products 10 is the same.

[0038] refer to Figure 3 and Figure 4 The lens positioning carrier 200 may include a positioning plate 210, which has a positioning groove 211 extending along a first direction. The positioning groove 211 can be used to place the lens product 10. When the lens product 10 is placed in the positioning groove 211, the lens circuit board 11 extends along the first direction. That is, if the lens product 10 includes two lenses 122, the two lenses 122 are arranged at intervals along the first direction.

[0039] The positioning groove 211 is equipped with a positioning station, which can be used to position one of the lenses 122 of the lens product 10 to ensure that the lens 122 to be focused can be accurately positioned with the lens 122 positioning carrier 210, thereby ensuring the accuracy of subsequent test results. Furthermore, the lens product 10 can also move relative to the positioning groove 211 along a first direction. For a lens product 10 with two lenses 122, this allows both lenses 122 to be positioned sequentially at the positioning station, thus completing the focusing work of both lenses 122.

[0040] like Figure 1 As shown, the focusing optical relay lens 300 is positioned above the lens positioning carrier 200, and the backlight plate 400 is positioned on the side of the focusing optical relay lens 300 away from the lens positioning carrier 200. At this time, the lens positioning carrier 200, the focusing optical relay lens 300, and the backlight plate 400 can be regarded as arranged along the second direction, which is perpendicular to the first direction.

[0041] A test image is displayed on the side of the backlight panel 400 facing the focusing optical repeater 300. During focusing, the lens 122 can achieve focusing by capturing an image of the test image. The focusing optical repeater 300 is directly opposite the positioning station. When the lens 122 is focusing, it can capture an image of the test image through the focusing optical repeater 300, allowing the lens 122 to simulate long-distance shooting.

[0042] Refer again Figure 3 The image acquisition device 500 may include two image transmission circuit boards 520 arranged along a first direction, each image transmission circuit board 520 may be provided with a second connection port 521. When focusing the lens 122, one of the second connection ports 521 can be used to connect to the first connection port 111 corresponding to the lens module 12 located at the positioning station, so that the image acquisition device 500 can drive the lens 122 to capture the image of the test picture on the backlight panel 400.

[0043] Each image transmission circuit board 520 is also provided with an output port 522, which may be, for example, a USB output port. The image transmission circuit board 520 can be connected to a test computer through the output port 522 to transmit the images captured by the lens 122 to the test computer. The test computer processes the images to determine whether the images are qualified, and thus determines whether the lens 122 has completed focusing.

[0044] Two positioning fixtures 510 may be provided on the fixture base plate 110, and the two positioning fixtures 510 are arranged along a first direction. Each positioning fixture 510 may be provided with a slot for positioning the image transmission circuit board 520. The shape of the slot may be adapted to the shape of the image transmission circuit board 520 so that when the image transmission circuit board 520 is placed in the slot, the image transmission circuit board 520 can be engaged in the slot, thereby ensuring that the image transmission circuit board 520 remains fixed during the focusing process of the lens 122.

[0045] Since the position of the second connection port 521 on the image transmission circuit board 520 is fixed, and the positioning station on the positioning slot 211 is also fixed, when the lens product 10 is placed in the positioning slot 211, the first connection port 111 can be quickly connected to the second connection port 521, thereby improving work efficiency.

[0046] Understandably, by setting up two image transmission circuit boards 520, when focusing the dual-lens product 10, the two lenses 122 are fixed in the positioning position one after the other, and the two lenses 122 can be controlled and driven by the two image transmission circuit boards 520 respectively. In this way, when focusing the dual-lens product 10, only the position of the lens 122 needs to be moved, without moving the image transmission circuit boards 520, which is convenient and quick, and can better improve work efficiency.

[0047] Furthermore, such as Figure 4 As shown, the positioning groove 211 can extend through the positioning carrier plate 210 along the first direction, that is, the two ends of the positioning groove 211 along the first direction are designed to be open. When the lens product 10 is placed in the positioning groove 211, it is convenient for the lens product 10 to move relative to the positioning groove 211. In addition, at least a part of the lens circuit board 11 can be located in the positioning groove 211, which can reduce the space occupied by the positioning carrier plate 210.

[0048] In some embodiments, reference is also made to Figure 2 and Figure 4 The positioning groove 211 located at the positioning station may be provided with at least two positioning holes 212. Correspondingly, the side of the lens circuit board 11 facing away from the lens 122 may be provided with positioning posts 112 that correspond one-to-one with the above-mentioned at least two positioning holes 212. When the lens product 10 is placed in the positioning groove 211, each positioning post 112 can be engaged into the corresponding positioning hole 212, thereby achieving the positioning of the lens product 10.

[0049] refer to Figure 5 The lens positioning carrier 200 may further include a lens fixing module, which may include a first drive module 230 and two clamping blocks 220. The two clamping blocks 220 are arranged along a third direction and are disposed on both sides of the positioning carrier plate 210. The third direction is perpendicular to the first direction and perpendicular to the second direction. The first drive module 230 may be disposed between the two clamping blocks 220 and is connected to the two clamping blocks 220 respectively, so as to drive the two clamping blocks 220 to move along the third direction respectively, thereby allowing the two clamping blocks 220 to move closer to each other or further away from each other.

[0050] When the lens product 10 is placed in the positioning station, the first drive module 230 can drive the two clamping blocks 220 to move closer to each other until the two clamping blocks 220 can cooperate to clamp the lens bracket 121, so that the two clamping blocks 220 and the lens bracket 121 are relatively fixed. After the lens 122 is focused, the first drive module 230 can drive the two clamping blocks 220 to move away from each other until the two clamping blocks 220 are no longer in contact with the lens bracket 121, so as to move the lens product 10 or remove the lens product 10 from the positioning slot 211.

[0051] In specific implementation, the first drive module 230 can be, for example, a cylinder. Based on this, such as... Figure 5 As shown, the lens 122 fixing module may also include two connecting plates 240, which are respectively connected to the connecting rod of the cylinder. Two clamping blocks 220 are respectively connected to the two connecting plates 240, so as to drive the connecting plates 240 to move through the connecting rod, thereby realizing the movement of the clamping blocks 220.

[0052] In this embodiment, the clamping block 220 and the connecting plate 240 are detachably connected. For example, the clamping block 220 can be connected to the connecting plate 240 by screws. Since the lens bracket 121 connected to different models of lenses 122 has different sizes, when applicable to different models of lenses 122, different clamping blocks 220 can be replaced according to the corresponding lens 122.

[0053] It should be noted that when different clamping blocks 220 are replaced, the initial spacing between the two clamping blocks 220 is different. When the first drive module 230 is used to drive the two clamping blocks 220 to move, the working state and time of the first drive module 230 do not need to be adjusted, thus adapting to different models of lens brackets 121.

[0054] Please refer to the above. Figure 3 and Figure 6 The lens focusing system in this embodiment may further include a relay lens mounting module 700, which may include a fixing base 710, a mounting base 720, and a second drive module 730. The mounting base 720 is mounted on the fixture base plate 110, the second drive module 730 is mounted on the mounting base 720, the fixing base 710 is connected to the second drive module 730, and the focusing optical relay lens 300 is fixedly connected to the fixing base 710.

[0055] The second drive module 730 can be used to drive the fixed base 710 to move along the second direction, thereby adjusting the distance between the focusing optical repeater 300 and the lens 122. When focusing the lens 122 with different focal lengths, adjusting the distance between the focusing optical repeater 300 and the lens 122 can meet the focusing requirements of the lens 122 with different focal lengths. In specific implementations, the second drive module 730 can be, for example, a telescopic cylinder to ensure the precise movement distance of the focusing optical repeater 300.

[0056] Furthermore, in this embodiment, the mounting base 720 can also move relative to the fixture base plate 110 along a third direction to adjust the relative position of the focusing optical repeater lens 300 with respect to the positioning station in the third direction. Since there may be errors in the installation position between the mounting base 720 and the fixture base plate 110, a deviation may occur between the center of the focusing optical repeater lens 300 and the positioning station. In this case, the mounting base 720 can be moved to align the focusing optical repeater lens 300 with the positioning station, thereby ensuring the focusing accuracy of the lens 122.

[0057] As an alternative implementation scheme, such as Figure 6 As shown, the mounting base 720 may be provided with a strip-shaped hole 711 extending in a third direction, and the fixture base plate 110 may be provided with mounting holes (not shown in the figure). The mounting base 720 and the fixture base plate 110 can be fixedly connected by screws fixed to the strip-shaped hole 711 and the mounting hole. When it is necessary to adjust the position of the mounting base 720, simply adjust the relative position between the screws and the strip-shaped hole 711 to change the relative position between the focusing optical relay lens 300 and the lens 122.

[0058] In some embodiments, reference Figure 3 The lens focusing system may also include a dispensing device (not shown) and a UV irradiation device 600. The dispensing device can be used to dispense adhesive between the lens 122 and the lens bracket 121, and the UV irradiation device 600 can be used to irradiate the lens module 12 after dispensing with UV light to improve the fixing effect between the lenses 122 and the lens bracket 121.

[0059] like Figure 3 and Figure 7As shown, the UV irradiation device 600 may include a rotating mounting base 610, a fixed bracket 620, and a plurality of UV lamp irradiation heads 630. The rotating mounting base 610 can be fixed to the fixture base plate 110, the fixed bracket 620 is connected to the rotating mounting base 610, and the UV lamp irradiation heads 630 are connected to the fixed bracket 620. The fixed bracket 620 can rotate relative to the rotating mounting base 610 about a first axis, which is parallel to a second direction, so that the plurality of UV lamp irradiation heads 630 can be positioned directly above the lens module 12, or the plurality of UV lamp irradiation heads 630 can be moved away from directly above the lens module 12.

[0060] In practical applications, when focusing the lens 122 using the focusing optical repeater 300, the UV lamp irradiation head 630 is moved away from the lens 122. After focusing the lens 122 is completed, the UV lamp irradiation head 630 can be rotated to be directly above the lens 122 to irradiate the lens module 12 after the adhesive has been applied.

[0061] As an optional implementation, a third drive module 611 may be provided on the rotary mounting base 610. The third drive module 611 is connected to a rotating shaft 612, and the fixed bracket 620 can be fixedly connected to the rotating shaft 612. The axis of the rotating shaft 612 extends along the second direction, and the third drive module 611 can drive the rotating shaft 612 to rotate around the axis of the rotating shaft 612, thereby realizing the rotation of the fixed bracket 620, that is, the rotation of the UV lamp irradiation head 630.

[0062] Each UV lamp irradiation head 630 is detachably connected to the fixed bracket, allowing for the increase or decrease of the number of UV lamp irradiation heads 630 to meet the irradiation needs of different lens product models 10. For example, the UV lamp irradiation head 630 can be mounted on the fixed bracket 620 via a mounting block 640, with the fixed bracket 620 passing through the mounting block 640, thus establishing the connection between the UV lamp irradiation head 630 and the fixed bracket 620. Furthermore, the angle between the mounting block 640 and the fixed bracket 620 is adjustable, ensuring that the irradiation directions of at least some UV lamp irradiation heads 630 do not overlap with those of other UV lamp irradiation heads 630. This allows multiple UV lamp irradiation heads 630 to irradiate the lens module 12 from different angles, thereby improving the curing efficiency of the UV adhesive.

[0063] In some embodiments, the mounting position between the backlight panel 400 and the test bracket 100 is adjustable to facilitate adjustment of the distance between the backlight panel 400 and the lens positioning carrier 200 in the second direction. Additionally, the backlight panel 400 may include an LED light source to illuminate the display, thereby ensuring stable clarity of the test image and guaranteeing the accuracy of the focusing results.

[0064] In addition, refer to again Figure 1The lens focusing system in this embodiment may also include an electrical control box 800, which can be connected to each drive module and the dispensing device to control the operation of each drive module and the amount of adhesive dispensed by the dispensing device.

[0065] Based on the specific structure of the lens focusing system in the above embodiments, when focusing the lens 122 using the lens focusing system, the following steps can be referred to:

[0066] Step 1: Place the lens product 10 to be focused into the lens positioning carrier 200, align the positioning hole 212 and the positioning post 112, confirm that the lens 122 is flat and in place with the positioning carrier plate 210, and then connect the first connection port 111 and the second connection port 521.

[0067] Step 2: Use the first drive module 230 to drive the two clamping blocks 220 to clamp and fix the lens module 12. At the same time, use the second drive module 730 to drive the focusing optical lens 122 to move towards the lens 122, so that the lens 122, the focusing optical relay lens 300 and the test image are in the focusing center position. Then use the image acquisition device 500 to focus the lens 122.

[0068] Step 3: After focusing is completed, the focusing optical relay lens 300 is driven away from the lens 122 by the second drive module 730, and then glue is applied to the lens module 12 by the glue dispensing device.

[0069] Step 4: After the adhesive is applied, rotate the UV lamp head 630 to the adhesive application position on the lens 122 to complete the adhesive application process.

[0070] Step 5: After irradiation is complete, remove the UV lamp irradiation head 630 and use the first drive module 230 to drive the clamping block 220 away from the lens 122, so that the clamping block 220 releases the lens 122.

[0071] Step 6: Fix the next lens 122 at the positioning station, and adjust the focus of lens 122 again according to the process of steps 1 to 5.

[0072] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
