Description

Technical Field

[0001] The present invention relates to the technical field related to camera module assembly, and in particular to a camera module assembly method and camera module assembly equipment. Background Art

[0002] In today's digital age, camera modules are widely used in various electronic devices, such as smartphones, tablets, security monitoring equipment, and in-vehicle cameras. Their image quality directly affects user experience and device functionality. However, the image quality of camera modules depends largely on assembly precision, with assembly tolerance being one of the key factors affecting this accuracy.

[0003] Active Alignment (AA) technology precisely controls the lens's six degrees of freedom (X, Y, and Z linear directions, as well as the rotational axes θx, θy, and θz). This ensures high concentricity between the lens' optical axis and the vertical axis of the chip (i.e., the image sensor). This active alignment method effectively reduces assembly tolerances in camera modules.

[0004] In some implementations, in order to reduce the assembly tolerance of the camera module and improve space utilization efficiency, the camera module can adopt a motor chip integrated design. During the assembly process of the camera module with a motor chip integrated design, glue is usually used for bonding and fixing to achieve a stable connection between the lens and components such as the motor chip assembly. However, in the current assembly process, the connection between the active alignment equipment and the glue fixing process is not smooth enough. Due to external forces in the glue dispensing process, glue characteristics and other factors, the position of the aligned components may shift again, which greatly reduces the effectiveness of the active alignment work and leads to a large assembly tolerance of the camera module.

[0005] Therefore, how to reduce the assembly tolerance during the camera module assembly process and optimize the connection between active alignment and gluing fixation processes are issues that need to be addressed urgently. Summary of the Invention

[0070] Please combine Figure 1 、 Figure 2 as well as Figure 3 As shown, the present application provides a camera module assembly device, including: a frame 100; an active alignment structure 200, including a first multi-dimensional correction module 210, a second multi-dimensional correction module 220 and a movable platform 230, the movable platform 230 is slidably connected to the frame 100, and the movable platform 230 is used to drive the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to move between the active alignment station and the dispensing station; the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are both arranged on the movable platform 230, the first multi-dimensional correction module 210 includes a first adjustment part 211 and a lens suction nozzle 211a, the lens suction nozzle 211a is provided with a first opening 221a1 and a plurality of second openings 221a2 located on the periphery of the first opening 221a1, the second multi-dimensional correction module 220 includes a second adjustment part 221 and a motor clamp 221a, the motor The fixture 221a is used to accommodate the motor chip assembly, and the first adjustment part 211 and the second adjustment part 221 are configured as follows: at the active alignment station, the first adjustment part 211 drives the lens suction nozzle 211a to move in multi-dimensional directions, and the second adjustment part 221 drives the motor fixture 221a to move in multi-dimensional directions, so as to install the lens sucked by the lens suction nozzle 211a into the motor chip assembly accommodated by the motor fixture 221a, and actively align the lens and the motor chip assembly; wherein, the first opening 221a1 provides an optical path channel for active alignment; and the glue dispensing structure 300, which is arranged on the frame 100, is configured as follows: when the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are located at the glue dispensing station, glue is injected from the multiple second openings 221a2, and the motor chip assembly and the lens installed in the motor chip assembly are glued and fixed with glue to obtain a camera module.

[0071] Furthermore, the movable sub-platform 230 includes a fixed portion fixed to the frame 100, and a sliding portion slidably connected to the fixed portion along a first direction. The first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are both arranged on the sliding portion of the movable sub-platform 230, so as to move the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to a position corresponding to the dispensing structure 300 by moving the sliding portion of the movable sub-platform 230, so as to perform dispensing and fixing of the lens and motor chip assembly. The first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the position corresponding to the dispensing structure 300, which means that the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the bottom of the dispensing structure 300. Specifically, the lens nozzle 211a, the motor clamp 221a and the dispensing head of the dispensing structure 300 are in the same vertical direction. Since the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the position corresponding to the dispensing structure 300 to perform dispensing, this position can also be called a dispensing station.

[0072] It should be understandable that since the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are both arranged on the sliding part of the movable platform 230, after the active alignment is completed, the two multi-dimensional correction modules are relatively fixed, and the sliding part of the movable platform 230 drives both to move to the dispensing station, which can ensure the consistency of the posture of the two multi-dimensional correction modules at the active alignment station and the dispensing station, avoid the introduction of movement deviation, and improve the installation accuracy between the lens and the motor chip assembly.

[0073] Furthermore, the active alignment structure 200 also includes a lens transfer module 240 and a visual laser module 250. The second multi-dimensional correction module 220, the lens transfer module 240, and the visual laser module 250 are all fixed to the sliding portion of the movable sub-platform 230. The first multi-dimensional correction module 210 is movably disposed on the sliding portion of the movable sub-platform 230. The first multi-dimensional correction module 210 is movable along the first direction relative to the sliding portion of the movable sub-platform 230. The first multi-dimensional correction module 210, the lens transfer module 240, and the visual laser module 250 are distributed along the first direction, so that by moving the position of the first multi-dimensional correction module 210, the lens nozzle 211a is moved to the position corresponding to the motor fixture 221a, the position corresponding to the lens transfer module 240, or the position corresponding to the visual laser module 250. The movement of the lens nozzle 211a to the position corresponding to the lens transfer module 240 means that the lens nozzle 211a moves directly above the lens transfer module 240, that is, the lens nozzle 211a and the lens transfer module 240 overlap along the third direction. The movement of the lens nozzle 211a to the position corresponding to the vision laser module 250 means that the lens nozzle 211a moves directly above the vision laser module 250, that is, the lens nozzle 211a and the vision laser module 250 overlap along the third direction.

[0074] In some possible implementations, a chip jig 221b is provided on the second adjustment portion 221, and a normally-open image chip is provided on the chip jig 221b. The normally-open image chip is used to determine the positional relationship between the lens and the motor chip assembly when the lens is installed in the motor chip assembly (such as the third positional relationship described later). The chip jig 221b and the motor fixture 221a are distributed along the first direction. Among them, the normally-open image chip is a sensor for continuous image capture that can maintain a "normally open" state at extremely low power consumption and respond to visual information in real time. The camera module assembly equipment can move the first multi-dimensional correction module 210 so that the lens nozzle 211a moves above the normally-open image chip, that is, the lens nozzle 211a overlaps with the normally-open image chip in the third direction. The first adjustment part 211 is used to drive the lens nozzle 211a to move along multiple directions, or the second adjustment part 221 is used to drive the chip fixture 221b to move along multiple directions to actively align the lens and the normally open chip, thereby determining the positional relationship between the lens and the motor chip assembly when the lens is assembled to the motor chip assembly.

[0075] Optionally, the lens transfer module 240, the chip fixture 221b, the motor fixture 221a, and the visual laser module 250 are distributed in sequence along the first direction.

[0076] Please refer to Figure 3 As shown, in some embodiments, the first multi-dimensional correction module 210 includes a first supporting portion 212 and a first adjusting portion 211, the lens nozzle 211a is a lens nozzle, the first supporting portion 212 is slidably disposed on the movable sub-platform 230, the first supporting portion 212 can slide along a first direction relative to the movable sub-platform 230, the first adjusting portion 211 can move along multi-dimensional directions relative to the first supporting portion 212, and the lens nozzle is disposed on the first adjusting portion 211 to adjust the multi-dimensional correction parameters of the lens nozzle through the first adjusting portion 211, thereby realizing adjustment of the lens position and angle.

[0077] Specifically, the lens nozzle extends along the second direction and overlaps with the second multi-dimensional correction module 220 (such as the motor clamp 221a or the chip fixture), the lens transfer module 240 or the visual laser module 250 along the third direction (ie, the vertical direction).

[0078] For example, Figure 4As shown, the lens nozzle is provided with a first opening 221a1, which can also be referred to as the middle opening of the lens nozzle. On the one hand, it is used to absorb the lens, and on the other hand, it can also prevent the lens from being blocked during active alignment. In addition, the lens nozzle is also provided with multiple second openings 221a2 around the first opening 221a1. The multiple second openings 221a2 correspond to the lens dispensing positions to facilitate dispensing. For example, the lens nozzle is provided with four second openings 221a2 around the first opening 221a1. These four second openings 221a2 can be evenly distributed along the circumference of the first opening 221a1. The diameter of the first opening 221a1 is larger than the diameter of the second opening 221a2. When the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are located at the dispensing station, the dispensing head of the dispensing structure 300 overlaps with the second opening 221a2 along the third direction.

[0079] Of course, in some other embodiments, the lens nozzle 211a may also be a flexible robotic arm or other parts transfer structure, as long as it can take and place the lens as needed without causing damage to the lens.

[0080] Please refer to Figure 3 As shown, in some embodiments, the second multi-dimensional correction module 220 includes a second support portion 222 and a second adjustment portion 221, the second support portion 222 is fixed to the movable sub-platform 230, and the second adjustment portion 221 can move in multi-dimensional directions relative to the second support portion 222, and the second adjustment portion 221 is fixed with a chip fixture 221b and a motor fixture 221a distributed along the first direction, wherein the chip fixture 221b is provided with a normally open chip in a power-on state, and the motor fixture 221a is used to accommodate the motor chip assembly to be assembled.

[0081] Please refer to Figure 6 As shown, in some embodiments, the glue dispensing structure 300 includes a glue dispensing slide 310, a glue dispensing unit 320 and a glue cleaning unit. The glue dispensing slide 310 is fixed to the frame 100, the glue cleaning unit is fixed to the glue dispensing slide 310, and the glue dispensing unit 320 is slidably connected to the glue dispensing slide 310 and is located on the upper side of the glue cleaning unit, so that the glue dispensing unit 320 can move along the glue dispensing slide 310 to directly above the glue cleaning unit.

[0082] Specifically, the glue dispensing structure 300 also includes a glue dispensing cylinder 330, which is slidably connected to the glue dispensing slide rail 310, and the glue dispensing part 320 is arranged at the moving end of the glue dispensing cylinder 330 to drive the glue dispensing part 320 to move along the third direction and perform glue dispensing when the lens nozzle reaches the glue dispensing position (the glue dispensing part 320, the motor clamp 221a and the lens nozzle overlap along the third direction), so as to glue and bond the motor chip assembly and the lens to be assembled to obtain a camera module.

[0083] In addition, the dispensing structure 300 further includes a dispensing vision module to enable the dispensing head of the dispensing portion 320 to be aligned with the dispensing position of the lens (ie, the second slot on the lens nozzle).

[0084] In some possible implementations, the camera module assembly equipment also includes a gantry loading and unloading structure 400 for transferring the lens and the motor chip assembly to be assembled to the active alignment structure 200 , and unloading the assembled camera module from the active alignment structure 200 .

[0085] Optionally, the gantry loading and unloading structure 400 is also used to perform automated optical inspection (AOI) on the lens, perform automated optical inspection on the assembled camera module, and perform exposure and curing on the assembled and glued camera module.

[0086] Please refer to Figure 5 As shown, in some embodiments, the gantry loading and unloading structure 400 includes a first automatic optical inspection module 410, a second automatic optical inspection module 420, an exposure light module 430, a slide rail module 440 and a nozzle module 450, wherein the first automatic optical inspection module 410 is used to inspect the assembled camera module (such as stain detection, etc.) and / or perform visual positioning on the motor chip assembly to be assembled, the second automatic optical inspection module 420 is used to perform automatic optical inspection (such as stain detection, etc.) on the lens to be assembled, the exposure light module 430 is used to solidify the glue in the camera module, the nozzle module 450 is used to suck and transfer the lens, motor chip assembly or camera module, the slide rail module 440 is used to provide the structure required for the movement of the nozzle module 450, and the exposure light module 430 is fixedly connected or slidably connected to the slide rail module 440.

[0087] The movable platform 230 is specifically used to drive the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to move between the active alignment station, the glue dispensing station and the exposure station; at the exposure station, the camera module and the exposure light module 430 overlap in the vertical direction, and the exposure light module 430 is used to solidify the glue in the camera module. The first opening 221a1 and the multiple second openings 221a2 provide an optical path channel for the exposure light module 430.

[0088] Specifically, the nozzle module 450 is slidably connected to the slide rail module 440 and is capable of reciprocating along the extension direction of the slide rail module 440. The exposure light module 430 is slidably connected or fixedly connected to the slide rail module 440, and the horizontal projections of the exposure light module 430 and the nozzle module 450 do not overlap to prevent the nozzle module 450 from colliding with the exposure light module 430 during movement. For example, the position of the exposure light module 430 on the slide rail module 440 along the third direction may be higher or lower than the height of the nozzle module 450.

[0089] More specifically, the nozzle module 450 includes a first nozzle, a second nozzle, and a third nozzle. The first nozzle is used to pick up the motor chip assembly, the second nozzle is used to pick up the lens, and the third nozzle is used to pick up the camera module. Optionally, the nozzle module 450 may also include a fourth nozzle for picking up lenses that fail the automatic optical inspection.

[0090] It is worth mentioning that please combine Figure 3 as well as Figure 5 As shown, when the mover platform 230 is located at a specific position, the motor fixture 221a and the projection of the exposure light module of the gantry loading and unloading structure 400 in the third direction at least partially overlap, so that the glue in the camera module can be solidified by the exposure light module 430. In addition, when the second multi-dimensional correction module 220 is located at a specific position, the motor fixture 221a and the projection of the first suction nozzle of the gantry loading and unloading structure 400 in the third direction at least partially overlap, so that the first suction nozzle can place the sucked motor chip assembly on the motor fixture 221a. When the second suction nozzle is located at a certain position of the slide rail module 440, the projection of the second suction nozzle and the lens transfer module 240 in the third direction overlap, so that the second suction nozzle can place the sucked lens on the lens transfer module 240. This specific position can also be called a loading and unloading station.

[0091] In this embodiment of the present application, an exposure light module 430 is mounted on the gantry loading and unloading structure 400. While the exposure light module 430 is exposing the glue in the camera module, the second suction nozzle of the gantry loading and unloading structure 400 can simultaneously pick up the next lens, perform automatic optical inspection on the next lens, and load the next lens onto the lens transfer module 240. Furthermore, the third suction nozzle picks up the next motor chip assembly to be assembled and performs initial posture calibration on it. After the camera module exposure is completed, the lens nozzle releases the lens of the camera module. The lens nozzle moves to pick up the next lens from the lens transfer module 240. The third suction nozzle picks up the camera module from the motor fixture 221a, and the second suction nozzle places the next motor chip assembly to be assembled onto the motor fixture 221a. The third suction nozzle moves the camera module above the first automatic optical inspection module 410 to perform automatic optical inspection on the camera module. After the inspection is completed, the camera module is placed into the corresponding material tray, completing the unloading of the camera module. In this way, the camera module can be unloaded, the next motor chip assembly to be assembled can be loaded, and the next lens can be sucked up from the lens transfer module 240 and then initially corrected in posture, thereby improving the assembly production efficiency of the camera module.

[0092] In some possible implementations, the camera module assembly device may further include a light source target plate structure 500, which is located above the active alignment structure 200. The light source target plate structure 500 is used for active alignment between the lens and the motor chip assembly, and / or for active alignment between the lens and the normally open image chip. The light source target plate structure 500 includes a target plate 510, on which an image for active alignment is provided. When actively aligning the lens and the motor chip assembly, the target plate 510, the lens nozzle 211a, and the motor fixture 221a overlap in a third direction to obtain an image on the target plate through the motor chip assembly. When actively aligning the lens and the normally open image chip, the target plate 510, the lens nozzle 211a, and the chip fixture 221b overlap in a third direction to obtain an image on the target plate through the normally open image chip.

[0093] Optionally, the light source target structure 500 may further include a lifting module 520. The supporting end of the lifting module 520 is fixed to the frame 100, and the target 510 is fixed to the lifting end of the lifting module 520. The lifting module 520 drives the target 510 to move up and down along the third direction. Optionally, the light source target structure 500 may further include a teleconverter module 530 to meet the object distance requirements during active alignment. The target 510 is positioned above the teleconverter module 530 along the third direction. The teleconverter module 530 is positioned above the active alignment structure 200 along the third direction. The active alignment structure 200 can be moved to the bottom side of the teleconverter module 530.

[0094] The movable platform 230 can drive the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to move to the position corresponding to the light source target plate module to perform active alignment between the lens and the motor chip assembly. Among them, the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the position corresponding to the light source target plate structure 500, which means that the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the bottom of the light source target plate structure 500. Specifically, the lens suction nozzle 211a, the motor clamp 221a and the target plate 510 and / or the teleconverter module 530 are in the same vertical direction. Since the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the position corresponding to the light source target plate structure 500 for active alignment, this position can also be called an active alignment station.

[0095] Optionally, the light source target structure 500 further includes a detection light source 540 for detecting bad pixels or stains on the lens and / or motor chip assembly. The detection light source 540 is positioned above the active alignment structure 200 along the third direction. The movable platform 230 can move the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 below the detection light source 540, which is then used to detect bad pixels or stains on the lens and / or motor chip assembly.

[0096] The teleconverter module 530 and the detection light source 540 are fixed on the frame 100 , or the teleconverter module 530 and the detection light source 540 are disposed on a fixed portion of the mover platform 230 .

[0097] In the embodiment of the present application, the sliding part of the movable platform 230 can drive the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to switch between the active alignment station, the dispensing station and the loading and unloading stations to meet the needs of multi-step parallelism, reduce equipment idle time and improve production efficiency.

[0098] Please combine Figure 5 、 Figure 7 as well as Figure 8 As shown, the camera module assembly equipment further includes at least one of the following: a tray transfer structure 600, including a first tray transfer module 610 and a second tray transfer module 620, the first tray transfer module 610 being used to transfer the second tray from the first hopper loading and unloading module 710 to the gantry loading and unloading structure 400, and to transfer the third tray to the first hopper loading and unloading module 710, wherein the second tray is used to place the motor chip assembly to be assembled, and the third tray is used to place the assembled camera module; the second tray transfer module 620 is used to transfer the first tray from the second loading hopper loading and unloading module to the gantry loading and unloading structure 400, wherein the first tray is used to place the lens to be assembled;

[0099] The silo loading and unloading structure 700 includes a first silo loading and unloading module 710 and a second silo loading and unloading module 720. The first silo loading and unloading module 710 is used to transfer the motor chip assembly to be assembled to the camera module assembly equipment of this application, and to transfer the assembled camera module to the next device. The second silo loading and unloading module 720 is used to transfer the lens to be assembled to the camera module assembly equipment of this application.

[0100] The gantry loading and unloading structure 400 , the light source target plate structure 500 , the tray transfer structure 600 , and the silo loading and unloading structure 700 are all disposed on the frame 100 .

[0101] Please refer to Figure 7As shown, in some embodiments, the silo loading and unloading structure 700 includes a first silo loading and unloading module 710 and a second silo loading and unloading module 720, wherein the first silo loading and unloading module 710 includes a first silo 711, the first silo 711 includes a plurality of second material trays, and the second material trays are used to place motor chip components to be assembled or assembled camera modules; the second silo loading and unloading module 720 includes a second silo 721, the second silo 721 includes a plurality of third material trays, and the third material trays are used to place lenses to be assembled.

[0102] Furthermore, the first silo loading and unloading module 710 also includes an assembly line connection part 712. The first silo 711 and the assembly line connection part 712 are distributed along the third direction. The assembly line connection part 712 is used to connect the first tray transfer module 610, so as to remove the second tray containing the motor chip assembly from the first silo 711 through the first tray transfer module 610, and place the third tray containing the camera module into the first silo 711.

[0103] It should be understood that the second tray, third tray, and first tray in this application are used to distinguish the products carried by the trays. The second tray, third tray, and first tray can be different names for the same tray when carrying different products. For example, when a tray contains a motor chip assembly to be assembled, it can be called the second tray; when all the motor chip assemblies in the tray are replaced with assembled camera modules, it can be called the third tray; when the tray carries both a motor chip assembly and a camera module, it can be called the second tray or the third tray, or it can have other names, and this application does not limit it here.

[0104] Please refer to Figure 8 As shown, in some embodiments, the tray transfer structure 600 includes a first tray transfer module 610 and a second tray transfer module 620, and the first tray transfer module 610 includes a tray pallet 611, a pallet bracket 612 and a movable shaft 613, wherein the tray pallet 611 is fixed to the upper end of the pallet bracket 612 along the third direction, and the lower end of the pallet bracket 612 along the third direction is slidingly connected to the movable shaft 613, and the pallet bracket 612 drives the tray pallet 611 to move along the extension direction of the movable shaft 613 to take the second tray out of the first silo 711, or place the third tray into the first silo 711.

[0105] When the support plate bracket 612 is located at the first position of the movable shaft 613, the projection of the tray support plate 611 and the first hopper 711 in the third direction at least partially overlaps, so that the tray support plate 611 can take out the second tray from the first hopper 711 and place the third tray into the first hopper 711;

[0106] When the tray support 612 is located at the second position of the movable axis 613, the projection of the tray tray 611 and the gantry loading and unloading structure 400 in the third direction at least partially overlaps, so that the gantry loading and unloading structure 400 can absorb the motor chip assembly from the second tray on the tray tray support 611, or the gantry loading and unloading structure 400 can place the assembled camera module into the third tray on the tray tray support 611.

[0107] Specifically, the first tray transfer module 610 also includes a tray pressure block 614, a clamping slider 615, a spring 616, a stop limit plate 617 and a stop fixed bracket 618, wherein the clamping slider 615 is slidably connected to the tray support plate 611 along the extension direction of the movable shaft 613, the two ends of the spring 616 are respectively connected to the clamping slider 615 and the tray support plate 611, the stop fixed bracket 618 is fixed on the movable shaft 613, and the stop limit plate 617 is fixed on the stop fixed bracket 618.

[0108] Please refer to Figure 9 As shown, when there is no tray, the spring 616 exerts a force on the pressing slider 615 in the left direction as shown in the figure, and the stopper 619 of the pressing slider 615 is blocked by the limiting surface below the tray support plate 611, so that the pressing slider 615 slides to the left together with the tray support plate 611;

[0109] Please refer to Figure 10 As shown, after the tray support plate 611 slides to a specific position, the stopper 619 of the pressing slider 615 is restricted by the stop plate 617, and the tray support plate 611 continues to slide to the left. Therefore, the spring 616 is further compressed, and the tray pressing block 614 moves to the right relative to the tray along with the pressing slider 615, thereby reserving more space on the tray support plate 611 for placing trays;

[0110] After the tray is placed on the tray support plate 611, the tray support plate 611 drives the tray and the limiting surface below the tray support plate 611 to move rightward, and the spring 616 gradually relaxes as the tray support plate 611 moves rightward.

[0111] Please refer to Figure 11 As shown, after the tray support plate 611 slides to a specific position, the right side of the tray contacts the tray pressing block 614, driving the pressing slider 615 to move rightward, thereby pressing the tray. The length of the spring 616 then remains unchanged. The speed at which the tray support plate 611 moves between the two specific positions can be determined by the thickness of the tray. For example, if the tray is thin, the speed needs to be slower. Conversely, if the tray is thick, the speed can be relatively faster to prevent the tray from popping out due to excessive speed before being pressed by the pressing block.

[0112] Furthermore, since the position of the limiting plate limits the maximum length of the tray and the position of the limiting surface limits the minimum length of the tray, the lengths of the two limiting plates can also be adjusted according to the length of the tray.

[0113] In addition, the second tray transfer module 620 is used to take out the first tray containing the lens from the second hopper 721. The structure of the second tray transfer module 620 is the same as that of the first tray transfer module 610, and will not be repeated here in this application.

[0114] Furthermore, when the support bracket 612 in the first tray transfer module 610 is located at the second position of the movable axis 613 and the first suction nozzle is located at the third position on the slide rail module 440, the projection of the first suction nozzle and the tray support plate 611 in the first tray transfer module 610 in the third direction at least partially overlaps, so that the first suction nozzle can suck the motor chip assembly to be assembled from the tray held on the first tray transfer module 610; after the first suction nozzle sucks the motor chip assembly, it drives the motor chip assembly to move to the top of the first automatic optical inspection module 410, and adjusts the posture of the motor chip assembly so that the lower bottom surface of the motor chip assembly is roughly flush with the sinking surface of the motor fixture 221a in the active alignment structure 200 for placing the motor chip assembly; after the adjustment is completed, the motor chip assembly is placed in the motor fixture 221a.

[0115] The tray bracket 612 in the second tray transfer module 620 is located at a certain position of the movable axis 613. When the second suction nozzle is located at the fourth position on the slide rail module 440, the projection of the second suction nozzle and the tray tray 611 of the second tray transfer module 620 in the third direction at least partially overlaps, so that the second suction nozzle can pick up the lens from the tray tray 611; the second suction nozzle can pick up the lens from the first tray held by the second tray transfer module 620, and drive the lens to move above the second automatic optical inspection module 420, and perform AOI inspection (such as stain detection) on the lens based on the second automatic optical inspection module 420; after the inspection passes, the second suction nozzle places the lens on the lens transfer module 240 of the active alignment structure 200; when performing AOI inspection on the lens, the lens posture can also be preliminarily adjusted so that the lower surface of the lens and the upper surface of the lens transfer module 240 in the active alignment structure 200 are roughly flush.

[0116] In some embodiments, the camera module assembly equipment includes multiple groups of active alignment structures 200, the glue dispensing structure 300 includes multiple glue dispensing units 320 and multiple glue cleaning units, and the gantry loading and unloading structure 400 includes multiple exposure light modules 430. In other words, the camera module assembly equipment includes multiple production lines for active alignment, glue dispensing, and exposure. It should be understood that since the time required for loading and unloading on the assembly line is less than the time required for alignment, glue dispensing, and exposure, by setting up multiple production lines for active alignment, glue dispensing, and exposure, the loading and unloading structure (i.e., the slide rail module 440 and the nozzle module 450) in the gantry loading and unloading structure 400 can be shared, thereby effectively improving production efficiency.

[0117] Exemplarily, the camera module assembly equipment includes two production lines for active alignment, gluing and exposure. The two production lines are arranged in parallel. The slide rail module 440 divides the two production lines into loading and unloading + exposure area, active alignment area and gluing area in turn. Correspondingly, the gantry loading and unloading structure 400 is located in the loading and unloading + exposure area, the active alignment structure 200 is located in the active alignment area, and the gluing structure 300 is located in the gluing area, so that some steps can be carried out simultaneously to improve assembly efficiency.

[0118] Please refer to Figure 12 As shown, the present application provides a camera module assembly method, which is applied to the camera module assembly equipment described above. The camera module assembly equipment includes a first multi-dimensional correction module, a second multi-dimensional correction module and a movable platform. The first multi-dimensional correction module and the second multi-dimensional correction module are arranged on the movable platform. The first multi-dimensional correction module includes a lens suction nozzle, and the lens suction nozzle is provided with a first opening and a plurality of second openings arranged along the circumference of the first opening. The camera module assembly method includes the following steps:

[0119] S200. Suction the lens through the lens nozzle;

[0120] S400. Assemble the lens into the motor chip assembly by adjusting the first multi-dimensional correction module or the second multi-dimensional correction module, wherein the motor chip assembly is placed in the second multi-dimensional correction module;

[0121] S500. Actively aligning the lens and the motor chip assembly, wherein the first opening provides an optical path for active alignment;

[0122] S600. After the lens and the motor chip assembly are actively aligned, the relative position between the lens and the motor chip assembly is maintained unchanged, and the first multi-dimensional correction module and the second multi-dimensional correction module are moved to the dispensing station through the movable platform;

[0123] S700. At the glue dispensing station, glue is injected from the plurality of second openings through the glue dispensing structure to bond the lens and the motor chip assembly to obtain a camera module.

[0124] Specifically, after the camera module assembly equipment uses the lens suction nozzle of the first multi-dimensional correction module to suck the lens from the lens transfer module, it drives the first multi-dimensional correction module to move in a first direction to move the lens above the motor chip assembly. Then, by adjusting the first adjustment part of the first multi-dimensional correction module or the second adjustment part of the second multi-dimensional correction module, the lens is assembled into the motor chip assembly. The camera module assembly equipment can move the first and second multi-dimensional correction modules to the active alignment station via the movable platform to perform active alignment between the lens and the motor chip assembly.

[0125] It is understandable that moving the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station by the movable sub-platform can occur before step S200 or step S400 or step S500. For example, the camera module assembly equipment can first move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station, and then execute step S200; for another example, the camera module assembly equipment can execute step S200, then move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station, and then execute step S400. For another example, the camera module assembly equipment can execute step S400, then move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station, and then execute step S500.

[0126] In this application, on the one hand, the movable platform can drive the two multi-dimensional correction platforms to move between the active alignment station and the dispensing station. After completing the active alignment of the lens and the motor chip assembly, the relative positions of the lens and the motor chip assembly are kept unchanged by the two multi-dimensional correction modules. The movable platform drives the two multi-dimensional correction modules to move together to the dispensing position, which can keep the relative positions of the lens and the motor chip assembly unchanged during the movement, avoid positional offset of the lens and the motor chip assembly during the movement, and reduce the assembly tolerance of the camera module.

[0127] On the other hand, the setting of the first opening and multiple second openings of the lens suction nozzle enables the lens suction nozzle to always maintain suction on the lens during the active alignment and dispensing process, which can optimize the connection between the active alignment and dispensing fixing process, avoid the displacement of the lens position during the active alignment and dispensing process, and further reduce the assembly tolerance of the camera module.

[0128] On the other hand, by first inserting the lens into the motor chip assembly and then fixing the two with glue, compared with the traditional method of first gluing and then adjusting, on the one hand, it can avoid the influence of glue adhesion and stress generated by curing, improve the active alignment accuracy while ensuring that the relative position of the lens and the motor remains unchanged; on the other hand, it can also avoid glue overflow, improve the uniformity of glue fixation, and improve the quality of glue dispensing.

[0129] Of course, in some other embodiments, the lens and the motor may also be fixed using other commonly used fixing methods, which are not listed one by one in this application.

[0130] In some embodiments, in step S600, after the lens and the motor chip assembly are actively aligned, the adjustment parts of the first multi-dimensional correction module and the second multi-dimensional correction module no longer move to ensure that the relative position of the lens and the motor chip assembly does not change after the active alignment.

[0131] In some embodiments, in step S600, after the movable platform moves the first multi-dimensional correction module and the second multi-dimensional correction module to the dispensing position, the dispensing head, the lens and the motor chip assembly correspond along the third direction (ie, the vertical direction).

[0132] Please refer to Figure 13 As shown, in some embodiments, step S500 includes:

[0133] S510. The first multi-dimensional correction module and the second multi-dimensional correction module are moved to the active alignment station by the movable platform;

[0134] S520. At the active alignment station, the lens position and / or angle are adjusted by the first multi-dimensional correction module, or the motor chip assembly position and / or angle are adjusted by the second multi-dimensional correction module, so that the image of the target plate obtained by the motor chip assembly meets the preset requirements, wherein, at the active alignment station, the lens, the motor chip assembly and the target plate are located in the same vertical direction.

[0135] Specifically, in step S510, the first multi-dimensional correction module and the second multi-dimensional correction module are moved to the active alignment station, that is, to the positions corresponding to the target plate and the teleconverter, that is, the positions corresponding to the target plate, the teleconverter, the lens and the motor chip assembly along the vertical direction.

[0136] In addition, in step S520, active alignment can be completed by adjusting the first multi-dimensional correction module or the second multi-dimensional correction module, and the optimal calibration method can be selected according to the product characteristics to match diverse production needs. For example, when the chip mass is large, the lens can be adjusted, and vice versa to optimize energy consumption and structural life.

[0137] In some embodiments, the light source target module also includes a detection light source. In the camera module assembly method, before or after step S400, the step of "detecting bad spots or stains on the lens and / or motor chip assembly through the detection light source" is also included.

[0138] It should be understandable that dust, scratches, bubbles or coating defects on the lens surface may cause fixed dark spots, blurred areas or abnormal reflections in the picture, that is, bad pixels. By detecting the optical defects of the lens in advance before assembling and fixing the lens and motor chip components, the losses caused by disassembly and scrapping of the subsequent camera module due to optical problems after assembly can be avoided, thereby reducing the defective rate.

[0139] Please refer to Figure 14 As shown, in some embodiments, the second multi-dimensional correction module includes a normally open image chip and a motor fixture, and the motor fixture is used to accommodate the motor chip assembly; before step S400, the camera module assembly method further includes:

[0140] S300a1 actively aligns the lens and the chip to obtain a first positional relationship between the lens and the chip;

[0141] S300a2 using the visual laser module to calibrate the coordinates and tilt angle of the photosensitive surface and the reference bottom surface to obtain a second positional relationship;

[0142] S300a3. Based on the first position relationship and the second position relationship, determine a third position relationship between the lens and the motor chip assembly, wherein the second position relationship includes a relative coordinate relationship and a relative tilt angle between the photosensitive surface of the normally open image chip and the reference bottom surface.

[0143] Step S400 includes: assembling the lens into the motor chip assembly based on the third positional relationship.

[0144] It should be noted that the present application does not limit the order of steps S300a1 and S300a2, as long as both are ensured to be before step S300a3. That is, the first position relationship and the second position relationship are obtained first, and then the third position relationship is determined based on the first position relationship and the second position relationship through step S300a3.

[0145] Specifically, the aforementioned always-on image chip is a sensor capable of continuous image capture, remaining in an "always-on" state while maintaining extremely low power consumption to respond to visual signals in real time. In step S500, the target, lens, and always-on image chip are arranged along a third direction. Using the powered always-on image chip as an optical reference, a pattern is projected through the target, and light passes through the lens to form an image on the always-on image chip. The image data captured by the always-on image chip is used to infer the positional deviation between the lens and the chip.

[0146] In the present application, the positional relationship is transmitted through a normally open image chip as a reference, thereby determining the position and angle (i.e., the third positional relationship) of the lens when it is inserted into the motor chip assembly through a positional relationship transmission chain (first positional relationship - second positional relationship - third positional relationship), so that the posture of the lens is determined before insertion, reducing the adjustment margin retained in the motor chip assembly, which is conducive to the miniaturization of the motor.

[0147] The first position relationship (lens-normally open image chip) is dynamically acquired through active alignment optical detection;

[0148] The second position relationship (normally open image chip - motor fixture) is obtained through pre-calibration of the visual laser module, recording the multi-dimensional correction parameter relationship between the surface of the normal open image chip and the motor support surface (motor chip assembly);

[0149] The third positional relationship (lens-motor chip assembly) performs coordinate transformation based on the first and second positional relationships, mapping the position and posture of the lens to the assembly coordinate system of the motor chip assembly to ensure precise alignment of the lens when inserted into the motor.

[0150] For further information, please refer to Figure 15 As shown, in some embodiments, the first positional relationship includes first coordinate information and first angle information of the lens after the lens and the normally-open image chip are actively aligned, the second positional relationship includes relative coordinate information and relative tilt angle between the photosensitive surface and the reference bottom surface, and the third positional relationship includes second coordinate information and second angle information of the lens when the lens is assembled into the motor chip assembly; step S400 includes:

[0151] S410. Maintaining the position and tilt angle of the reference bottom surface unchanged, adjust the horizontal position of the lens according to the second coordinate information so that the lens and the motor chip assembly are located in the same vertical direction;

[0152] S420. Adjust the vertical position and tilt angle of the lens based on the second coordinate information and the second angle information, so as to assemble the lens into the motor chip assembly.

[0153] When the image captured on the normally-open image chip meets the requirements, the first multi-dimensional correction module and the second multi-dimensional correction module stop adjusting the position or angle of the lens and / or the normally-open image chip, and obtain the first coordinate information and first angle information of the lens. For example, the first coordinate information of the lens is expressed as (X1, Y1, Z1), and the first angle information can be expressed as (θx1, θy1, θz1).

[0154] The second positional relationship can include a coordinate offset and an angular offset between the reference bottom surface of the motor fixture and the photosensitive surface (i.e., the top surface) of the normally-on chip. The second positional relationship can be expressed as (ΔX, ΔY, ΔZ, Δθx, Δθy, Δθz).

[0155] The second coordinate information can be obtained by adding the first coordinate information and the coordinate offset. For example, the second coordinate information can be obtained by adding the first coordinate information and the coordinate offset, and the second coordinate information can be expressed as (X1+ΔX, Y1+ΔY, Z1+ΔZ). The second angle information can be obtained by adding the first angle information and the angle offset. For example, the second angle information can be obtained by adding the first angle information and the handover offset, and the second angle information can be expressed as (θx1+Δθx, θy1+Δθy, θz1+Δθz).

[0156] After the camera module assembly equipment obtains the second coordinate information and the second angle information, it keeps the adjustment part of the second multi-dimensional correction module stationary, and moves the lens through the first multi-dimensional correction module so that the position and angle of the lens correspond to the second multi-dimensional correction data, thereby successfully assembling the lens into the motor chip assembly.

[0157] Specifically, the camera module assembly equipment first adjusts the horizontal position of the lens according to the second coordinate information, aligning the lens and the motor chip assembly in the same vertical direction. In other words, the camera module assembly equipment uses the first multi-dimensional correction module to move the lens above the motor chip assembly. At this point, the lens's XY coordinates satisfy (X1+ΔX, Y1+ΔY). The camera module can adjust the lens's angle information first, then its vertical position.

[0158] For example, in order to avoid collision between the lens and the motor chip assembly when adjusting the horizontal position of the lens, the camera module assembly equipment can move the lens in the vertical direction before adjusting the horizontal position of the lens, and then adjust the horizontal position of the lens.

[0159] As another example, to prevent the lens and the motor chip assembly from colliding with each other when adjusting the horizontal position of the lens, the position of the motor chip assembly can be lower than the position of the normally-open image chip, that is, the position of the reference bottom surface of the motor fixture is lower than the position of the photosensitive surface of the normally-open image chip (that is, ΔZ < 0). For example, the height difference between the reference surface of the motor fixture and the photosensitive surface of the normally-open image chip is greater than the height of the motor chip assembly, that is, the absolute value of ΔZ is greater than the height of the motor chip assembly. In this way, after active alignment between the lens and the normally-open image chip is completed, there is a height difference between the lens and the motor chip assembly. When the camera module assembly equipment adjusts the horizontal position of the lens on the XY plane, the lens and the motor chip assembly will not collide with each other.

[0160] In this application, the camera module assembly equipment first adjusts the horizontal position of the lens, and then adjusts the vertical position and angle of the lens, which can avoid collision between the lens and the motor chip assembly during assembly. At the same time, the lens is assembled to the motor chip assembly according to the determined coordinate information and angle information, which can allow a smaller space to be reserved in the motor chip assembly to assemble the lens. The lens and the motor chip assembly can be assembled with a smaller gap, which is conducive to the miniaturization of the motor chip assembly and the camera module.

[0161] It should be understandable that by using the constantly open image chip as an intermediate reference, it is also possible to separate the error sources of lens optical calibration and motor chip assembly mechanical assembly, avoid secondary deviations caused by internal adjustments of the motor chip assembly in traditional methods, and improve the accuracy of active calibration.

[0162] In addition, because the present application first determines the precise relative position of the lens and motor chip assembly (i.e., the third positional relationship), and then directly assembles the assembly based on the data from the third positional relationship, it is possible to suppress positional offsets caused by active alignment adjustments in traditional methods and reduce the uncertainty associated with dynamic adjustments. Furthermore, in some embodiments, step S400 includes adjusting the lens position and / or angle via a first multidimensional correction module, or adjusting the position and / or angle of the normally-open image chip via a second multidimensional correction module, so that the image of the target captured by the normally-open image chip meets preset requirements. In other words, step S400 can complete active alignment by adjusting either the first multidimensional correction module or the second multidimensional correction module.

[0163] Specifically, active alignment is completed by adjusting the lens, that is, adjusting the lens position and inclination through the first multi-dimensional correction module, using the normally-open image chip to obtain the target plate image, and when the image obtained by the normally-open image chip meets the requirements, determining the position and inclination of the lens and the normally-open image chip; active alignment is completed by adjusting the normally-open image chip, that is, adjusting the position and inclination of the normally-open image chip through the second multi-dimensional correction module, using the normally-open image chip to obtain the target plate image, and when the image obtained by the chip meets the requirements, determining the position and inclination of the lens and the chip.

[0164] Of course, in some other embodiments, active alignment can also be achieved by adjusting the lens and the normally-on image chip simultaneously, that is, by adjusting the first multi-dimensional correction module and the second multi-dimensional correction module simultaneously. The specific adjustment process will not be repeated here.

[0165] Please refer to Figure 16 As shown, in some embodiments, the camera module assembly device further includes a vision module. Before step S400, the camera module assembly method further includes:

[0166] S300b. Using the reference bottom surface of the target plate or motor fixture as a reference, adjust the posture of the lens so that the horizontal reference surface of the lens is flush with the target plate or the reference bottom surface, wherein the reference bottom surface is used to place the motor chip assembly, the horizontal reference surface of the lens is perpendicular to the optical axis of the lens, and the target plate is used for active alignment between the lens and the motor chip assembly.

[0167] It should be understandable that by adjusting the horizontal reference plane of the lens, the initial posture error of the lens can be eliminated, ensuring that it is parallel to the horizontal plane of the target plate or the chip surface in the motor chip assembly before active alignment, providing a more accurate starting point for subsequent active alignment steps.

[0168] It's worth noting that different adjustment methods can be selected based on actual needs. Specifically, lens leveling can be performed using a target plate or the base surface of the motor fixture as a reference. Furthermore, in actual production, step S300b can be performed after multiple rounds of assembly steps to eliminate accumulated errors during the production process and ensure assembly accuracy.

[0169] Please refer to Figure 17 As shown, in some embodiments, before step S200, the camera module assembly method further includes:

[0170] S100. Perform automatic optical inspection on the lens.

[0171] Specifically, in step S100, the camera module assembly equipment can suck the lens from the first material tray through the second suction nozzle in the gantry loading and unloading structure, and move the lens to directly above the second automatic optical inspection module, and use the second automatic optical inspection module to perform automatic optical inspection on the lens.

[0172] Automated optical inspection includes, but is not limited to, detecting stains and scratches on the lens surface. If the diameter of a stain or scratch on the lens surface is greater than or equal to a certain threshold (e.g., 20 microns), the lens is deemed to have failed the automated optical inspection. The lens can then be picked up by the fourth nozzle and placed in the waste tray. If the stain on the lens surface is smaller than the threshold, the lens is deemed to have passed the automated optical inspection and placed on the lens transfer module for subsequent lens assembly.

[0173] It should be understandable that by performing automatic optical inspection before active alignment, defective lenses can be eliminated in advance to avoid waste in subsequent processes, thereby ensuring that the lenses involved in active alignment are flawless, preventing defective products from flowing into the active alignment step, and reducing the rework rate.

[0174] Furthermore, in some embodiments, before step S200, the process further includes the step of obtaining the position of the lens within the lens transfer module using a vision module. Obtaining the lens position parameters using the vision module facilitates subsequent lens nozzle extraction from the lens transfer module, thereby reducing the likelihood of extraction failure, improving automation stability, and reducing the amount of error introduced by extraction deviation, further enhancing installation accuracy.

[0175] Please refer to Figure 13 As shown, in some embodiments, after step S700, the camera module assembly method further includes:

[0176] S810. The first multi-dimensional correction module and the second multi-dimensional correction module are moved to the exposure station by the movable platform;

[0177] S820. At the exposure station, the glue in the camera module is cured by the exposure lamp, wherein the first opening and the plurality of second openings provide a light path for the exposure lamp;

[0178] S830. After the exposure is completed, the lens nozzle releases the lens.

[0179] Specifically, after glue dispensing is completed, the camera module assembly equipment moves the first and second multi-dimensional correction modules to the exposure station via the movable platform. The exposure light module on the gantry loading and unloading structure cures the glue in the camera module. After exposure is complete, the lens nozzle releases the lens, and the third nozzle of the gantry loading and unloading structure removes the camera module from the motor fixture. The camera module is then moved above the first automatic optical inspection module for automatic optical inspection. This automatic optical inspection includes, but is not limited to, detecting the presence of residual fluorescent glue on the camera module and detecting surface stains.

[0180] Please refer to Figure 13 As shown, in some embodiments, after step S830, the camera module assembly method further includes:

[0181] S910. Move the second multi-dimensional correction module to the active alignment station through the movable platform;

[0182] S920. Use a standard plate to inspect the imaging quality of the camera module.

[0183] In this application, the imaging quality of the camera module can be tested using a target plate and teleconverter before the camera module is cut. Specifically, the actuator platform moves the second multi-dimensional correction module to the active alignment station. At this point, the camera module, target plate, and teleconverter are aligned in the same vertical direction. The camera module captures an image of the target plate, and the image quality of the camera module is tested using the image of the target plate captured by the camera module.

[0184] Furthermore, in some embodiments, while the glue in the motor chip assembly is being cured by an exposure lamp, the camera module assembly device can absorb the next lens from the first material tray, that is, some steps in the front and rear wheel assembly processes can be performed in parallel.

[0185] It should be understood that by adopting a multi-step parallel design, parallelizing exposure and curing with lens loading, and parallelizing motor loading with lens transfer, it is possible to reduce equipment idle and waiting time, optimize production cycle time, and improve production efficiency. Of course, if the equipment allows, other steps in the assembly process of the same or different wheels can also be parallelized to optimize production efficiency. This application does not provide a detailed list of examples.

[0186] In some embodiments, before step S200, the camera module assembly method further includes:

[0187] Adjusting the posture of the motor chip assembly through the vision module so that the lower surface of the motor chip assembly is flush with the reference bottom surface of the motor fixture of the second multi-dimensional correction module;

[0188] Place the motor chip assembly into the motor fixture.

[0189] This vision module can be the first automated optical inspection module described above, or another module with visual positioning capabilities installed on the gantry loading and unloading structure. By adjusting the position of the motor chip assembly using visual feedback from the vision module, the motor chip assembly's lower surface after insertion can be aligned with the reference bottom surface (i.e., contact surface) of the motor fixture, improving the reference surface consistency for subsequent active alignment and thus reducing mechanical assembly errors.

[0190] It is worth mentioning that the vision module can not only be used for visual positioning of motor chip components to be assembled, but also for automatic optical inspection of camera modules after assembly. It is highly versatile and effectively reduces equipment costs.

[0191] In addition, the present application does not limit the order of the step "adjusting the posture of the motor chip component through the visual module" and step S100, as long as both are before step S200.

[0192] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several variations and improvements can be made, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of this invention should be based on the attached claims.
