Description

Technical Field

[0001] The present invention relates to the technical field related to the assembly of camera modules, and particularly to a method and an apparatus for assembling a camera module. Background Art

[0002] In today's digital age, camera modules are widely used in various electronic devices, such as smartphones, tablets, security monitoring devices, vehicle-mounted cameras, etc. The imaging quality thereof directly affects the user experience and the functionality of the devices. And the imaging quality of the camera module depends to a large extent on the assembly accuracy, among which the assembly tolerance is one of the key factors affecting the assembly accuracy.

[0003] Active Alignment (AA) technology precisely controls the six degrees of freedom of the lens in three linear directions of X, Y, Z and three rotational directions of θx, θy, θz to achieve the high concentricity of the optical axis of the lens and the perpendicular axis of the surface of the chip (i.e., the image sensor (SENSOR)). Through this active alignment method, the assembly tolerance of the camera module can be effectively reduced.

[0004] In some implementation manners, in order to reduce the assembly tolerance of the camera module and improve the space utilization efficiency, the camera module may adopt an integrated design of the motor and the chip. During the assembly process of the camera module with the integrated design of the motor and the chip, in order to achieve the stable connection of components such as the lens and the motor chip assembly, glue is usually used for bonding and fixing. However, in the current assembly process, the connection between the active alignment device and the dispensing and fixing process is not smooth enough. Due to factors such as the external force during the dispensing process and the glue characteristics, the positions of the already aligned components may shift again, greatly reducing the working effect of the active alignment and resulting in a large assembly tolerance of the camera module.

[0005] Therefore, how to reduce the assembly tolerance during the assembly process of the camera module and optimize the connection between the active alignment and the dispensing and fixing process is an urgent problem to be solved. Summary of the Invention

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, the present application provides an imaging 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 mover platform 230, the mover platform 230 is slidably connected to the frame 100, and the mover 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; both the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are arranged on the mover 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 fixture 221a, the motor 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: at the active alignment station, the first adjustment part 211 drives the lens suction nozzle 211a to move in multiple directions, and the second adjustment part 221 drives the motor fixture 221a to move in multiple 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 perform active alignment on the lens and the motor chip assembly; wherein, the first opening 221a1 provides an optical path channel for active alignment; and a dispensing structure 300, arranged on the frame 100, configured as: when the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are at the dispensing station, inject glue from the plurality of second openings 221a2, and use the glue to dot and fix the motor chip assembly and the lens installed in the motor chip assembly to obtain an imaging module.

[0071] Furthermore, the mover platform 230 includes a fixed part fixed to the frame 100 and a sliding part slidably connected to the fixed part in the first direction. The first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are both disposed on the sliding part of the mover platform 230. By moving the sliding part of the mover platform 230, the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are moved to positions corresponding to the dispensing structure 300 to perform dispensing and fixing on the lens and the motor chip assembly. The first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 moving to positions corresponding to the dispensing structure 300 means that the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are moved below the dispensing structure 300. Specifically, the lens nozzle 211a, the motor fixture 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 are moved to positions corresponding to the dispensing structure 300 for dispensing, this position can also be referred to as the dispensing station.

[0072] It should be understood that since the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 are both disposed on the sliding part of the mover platform 230, after the active alignment is completed, the two multi-dimensional correction modules are relatively fixed. Driven by the sliding part of the mover platform 230, the two are moved to the dispensing station, which can ensure the pose consistency of the two multi-dimensional correction modules at the active alignment station and the dispensing station, avoid introducing movement deviation, and improve the installation accuracy between the lens and the motor chip assembly.

[0073] Furthermore, the active alignment structure 200 further includes a lens transfer module 240 and a vision laser module 250. The second multi-dimensional correction module 220, the lens transfer module 240 and the vision laser module 250 are all fixed to the sliding part of the mover platform 230. The first multi-dimensional correction module 210 is movably disposed on the sliding part of the mover platform 230, and the first multi-dimensional correction module 210 can move along the first direction relative to the sliding part of the mover platform 230. The first multi-dimensional correction module 210, the lens transfer module 240 and the vision laser module 250 are distributed along the first direction. By moving the position of the first multi-dimensional correction module 210, the lens nozzle 211a is moved to a position corresponding to the motor fixture 221a, a position corresponding to the lens transfer module 240 or a position corresponding to the vision laser module 250. Among them, the lens nozzle 211a moving to a position corresponding to the lens transfer module 240 means that the lens nozzle 211a is moved directly above the lens transfer module 240, that is, the lens nozzle 211a and the lens transfer module 240 overlap in the third direction. The lens nozzle 211a moving to a position corresponding to the vision laser module 250 means that the lens nozzle 211a is moved directly above the vision laser module 250, that is, the lens nozzle 211a and the vision laser module 250 overlap in the third direction.

[0074] In some possible implementations, a chip fixture 221b is provided on the second adjustment part 221. A normally-open pattern chip is provided on the chip fixture 221b. The normally-open pattern chip is used to determine the positional relationship (such as the third positional relationship described later) between the lens and the motor chip assembly when the lens is loaded into the motor chip assembly. The chip fixture 221b and the motor fixture 221a are distributed along the first direction. Among them, the normally-open pattern chip is a sensor for continuous image capture, which can maintain the "normally-open" state at extremely low power consumption and respond to visual information in real time. The camera module assembly device can move the first multi-dimensional correction module 210 so that the lens suction nozzle 211a moves above the normally-open pattern chip, that is, the lens suction nozzle 211a overlaps with the normally-open pattern chip in the third direction. The first adjustment part 211 is used to drive the lens suction nozzle 211a to move in multi-dimensional directions, or the second adjustment part 221 is used to drive the chip fixture 221b to move in multi-dimensional directions to actively align the lens and the normally-open pattern chip, and then determine 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 vision laser module 250 are sequentially distributed 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 support part 212 and a first adjustment part 211. The lens suction nozzle 211a is a lens suction nozzle. The first support part 212 is slidably provided on the mover platform 230. The first support part 212 can slide relative to the mover platform 230 along the first direction. The first adjustment part 211 can move in multi-dimensional directions relative to the first support part 212. The lens suction nozzle is provided on the first adjustment part 211 to adjust the multi-dimensional correction parameters of the lens suction nozzle through the first adjustment part 211, thereby realizing the adjustment of the position and angle of the lens.

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

[0078] Exemplarily, such as Figure 4As shown, the lens suction nozzle is provided with a first opening 221a1, which can also be referred to as the middle opening of the lens suction nozzle. On the one hand, it is used to suck the lens, and on the other hand, it can also prevent the lens from being blocked during active alignment. In addition, the lens suction nozzle is further provided with a plurality of second openings 221a2 around the first opening 221a1, and the plurality of second openings 221a2 correspond to the lens dispensing positions to facilitate the dispensing operation. For example, the lens suction nozzle is provided with four second openings 221a2 around the first opening 221a1, and these four second openings 221a2 can be evenly distributed along the circumferential side of the first opening 221a1. Among them, 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 in the third direction.

[0079] Of course, in some other embodiments, the lens suction nozzle 211a can also be other part transfer structures such as a flexible manipulator, as long as it can pick and place the lens as needed and will not cause 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 mover platform 230, and the second adjustment portion 221 can move relative to the second support portion 222 in multiple directions. A chip fixture 221b and a motor fixture 221a distributed in the first direction are fixed on the second adjustment portion 221. Among them, a normally open chip in the energized state is provided on the chip fixture 221b, 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 dispensing structure 300 includes a dispensing slide rail 310, a dispensing portion 320, and a glue cleaning portion. The dispensing slide rail 310 is fixed to the frame 100, the glue cleaning portion is fixed to the dispensing slide rail 310, and the dispensing portion 320 is slidably connected to the dispensing slide rail 310 and is located above the glue cleaning portion, so that the dispensing portion 320 can move along the dispensing slide rail 310 to directly above the glue cleaning portion.

[0082] Specifically, the dispensing structure 300 further includes a dispensing cylinder 330. The dispensing cylinder 330 is slidably connected to the dispensing slide rail 310, and the dispensing portion 320 is disposed on the moving end of the dispensing cylinder 330. When the lens suction nozzle reaches the dispensing position (the dispensing portion 320, the motor fixture 221a, and the lens suction nozzle overlap in the third direction), it drives the dispensing portion 320 to move in the third direction and perform dispensing, bonding the motor chip assembly to be assembled and the lens with glue to obtain an imaging module.

[0083] In addition, the dispensing structure 300 further includes a dispensing vision module, so that the dispensing head of the dispensing part 320 can be aligned with the dispensing position of the lens (i.e., the second slot on the lens suction nozzle).

[0084] In some possible implementations, the camera module assembly device further includes a gantry loading and unloading structure 400, which is used to transfer the lens and the motor chip assembly to be assembled to the active alignment structure 200, and unload the assembled camera module from the active alignment structure 200.

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

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

[0087] The mover 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 dispensing station, and the exposure station; at the exposure station, the camera module and the exposure lamp module 430 overlap in the vertical direction, and the exposure lamp module 430 is used to cure the glue in the camera module, and the first opening 221a1 and the plurality of second openings 221a2 provide a light path channel for the exposure lamp module 430.

[0088] Specifically, the suction nozzle module 450 is slidably connected to the slide rail module 440, and the suction nozzle module 450 can reciprocate along the extension direction of the slide rail module 440; the exposure lamp module 430 is slidably connected or fixedly connected to the slide rail module 440, and the projections of the exposure lamp module 430 and the suction nozzle module 450 in the horizontal direction do not overlap, so as to prevent the suction nozzle module 450 from colliding with the exposure lamp module 430 during movement. For example, the position of the exposure lamp module 430 on the slide rail module 440 is higher or lower than the height of the suction nozzle module 450 in the third direction.

[0089] More specifically, the nozzle module 450 includes a first nozzle, a second nozzle, and a third nozzle. Among them, 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 further include a fourth nozzle, and the fourth nozzle is used to pick up the lens that fails the automatic optical inspection.

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

[0091] In the embodiment of the present application, the exposure lamp module 430 is arranged on the gantry loading and unloading structure 400. During the process of exposing the glue in the camera module by the exposure lamp module 430, the second nozzle of the gantry loading and unloading structure 400 can simultaneously pick up the next lens, perform automatic optical inspection on the next lens, load the next lens onto the lens transfer module 240, and the third nozzle picks up the next motor chip assembly to be assembled and performs attitude initial correction on it, etc. After the exposure of the camera module is completed, the lens nozzle can release the lens of the camera module, then the lens nozzle moves and picks up the next lens from the lens transfer module 240, the third nozzle picks up the camera module from the motor fixture 221a, and the second nozzle places the next motor chip assembly to be assembled on the motor fixture 221a. The third nozzle moves the camera module above the first automatic optical inspection module 410 to perform automatic optical inspection on the camera module, and after the inspection is completed, places the camera module in the corresponding tray to complete the unloading of the camera module. In this way, operations such as unloading the camera module, loading the next motor chip assembly to be assembled, and performing attitude initial correction after picking up the next lens from the lens transfer module 240 can be synchronized, thereby improving the assembly production efficiency of the camera module.

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

[0093] Optionally, the light source reticle 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 reticle 510 is fixed to the lifting end of the lifting module 520 to drive the reticle 510 to lift along the third direction through the lifting module 520. Optionally, the light source reticle structure 500 may further include a teleconverter module 530 for meeting the object distance requirements during active alignment. The reticle 510 is located above the teleconverter module 530 in the third direction, the teleconverter module 530 is arranged above the active alignment structure 200 in the third direction, and the active alignment structure 200 can move to the lower side of the teleconverter module 530.

[0094] The mover 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 reticle module for 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 moving to the position corresponding to the light source reticle structure 500 means that the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 move to the lower side of the light source reticle structure 500. Specifically, the lens nozzle 211a, the motor fixture 221a, and the reticle 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 reticle structure 500 for active alignment, this position can also be referred to as the active alignment station.

[0095] Optionally, the light source reticle structure 500 further includes a detection light source 540 for detecting dead pixels or stains on the lens and / or the motor chip assembly. The detection light source 540 is disposed on the upper side of the active alignment structure 200 along the third direction. The mover platform 230 can drive the first multi-dimensional correction module 210 and the second multi-dimensional correction module 220 to move below the detection light source 540, and use the detection light source 540 to detect dead pixels or stains on the lens and / or the motor chip assembly.

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

[0097] In the embodiment of the present application, the sliding portion of the mover 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 station to meet the requirements of multi-step parallelism, reduce the idle time of the equipment, and improve the production efficiency.

[0098] Please refer to Figure 5 、 Figure 7 and Figure 8 As shown, the camera module assembly device 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 is used to transfer the second tray from the first bin loading and unloading module 710 to the gantry loading and unloading structure 400, and transfer the third tray to the first bin loading and unloading module 710. 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 bin loading and unloading module to the gantry loading and unloading structure 400. The first tray is used to place the lens to be assembled.

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

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

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

[0102] Further, the first bin loading and unloading module 710 further includes a pipeline connection part 712. The first bin 711 and the pipeline connection part 712 are distributed along the third direction. The pipeline connection part 712 is used to connect the first tray transfer module 610, so as to take out the second tray containing the motor chip assembly from the first bin 711 through the first tray transfer module 610, and place the third tray containing the camera module into the first bin 711.

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

[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. The first tray transfer module 610 includes a tray support plate 611, a support plate bracket 612 and a moving shaft 613. Among them, the tray support plate 611 is fixed at the upper end of the support plate bracket 612 along the third direction, and the lower end of the support plate bracket 612 along the third direction is slidably connected to the moving shaft 613. The support plate bracket 612 drives the tray support plate 611 to move along the extension direction of the moving shaft 613, so as to take out the second tray from the first bin 711, or place the third tray into the first bin 711.

[0105] Among them, when the support plate bracket 612 is located at the first position of the moving shaft 613, the projection of the tray support plate 611 and the first bin 711 in the third direction at least partially overlap, so that the tray support plate 611 can take out the second tray from the first bin 711, and place the third tray into the first bin 711;

[0106] When the pallet support 612 is at the second position of the moving shaft 613, the projection of the pallet 611 in the third direction overlaps at least partially with the gantry loading and unloading structure 400, so that the gantry loading and unloading structure 400 can pick up the motor chip assembly from the second tray on the pallet 611, or the gantry loading and unloading structure 400 can place the assembled camera module onto the third tray on the pallet 611.

[0107] Specifically, the first tray transfer module 610 further includes a tray pressing block 614, a pressing slider 615, a spring 616, a stop limiting plate 617, and a stop fixing bracket 618. Among them, the pressing slider 615 is slidably connected to the pallet 611 along the extension direction of the moving shaft 613. The two ends of the spring 616 are respectively connected to the pressing slider 615 and the pallet 611. The stop fixing bracket 618 is fixed on the moving shaft 613, and the stop limiting plate 617 is fixed on the stop fixing bracket 618.

[0108] Please refer to Figure 9 As shown, in the case of no tray, the spring 616 exerts a leftward acting force on the pressing slider 615, and the stopper 619 of the pressing slider 615 is blocked by the limiting surface below the pallet 611, so that the pressing slider 615 and the pallet 611 slide leftward together;

[0109] Please refer to Figure 10 As shown, after the pallet 611 slides to a specific position, the stopper 619 of the pressing slider 615 is restricted by the stop limiting plate 617, while the pallet 611 continues to slide leftward. Therefore, the spring 616 is further compressed, and the tray pressing block 614 moves rightward relative to the tray along with the pressing slider 615, so as to reserve more positions on the pallet 611 for placing the tray;

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

[0111] Please refer to Figure 11 As shown, after the pallet 611 slides to a specific position, the right side of the tray contacts the tray pressing block 614 and drives the pressing slider 615 to move rightward together, so as to be able to press the tray. Subsequently, the length of the spring 616 remains unchanged. Among them, the moving speed of the pallet 611 between two specific positions can be determined by the thickness of the tray. For example, in the case of a thinner tray, the speed needs to be slower. On the contrary, if the tray is thicker, the moving speed can be relatively faster to prevent the tray from popping out due to too fast a speed before being pressed by the pressing block.

[0112] Further, since the position of the limiting plate restricts the maximum length of the tray, and the position of the limiting surface restricts 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 lenses from the second bin 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 elaborated herein in this application.

[0114] Further, when the tray support 612 in the first tray transfer module 610 is at the second position of the moving shaft 613 and the first suction nozzle is at the third position on the slide rail module 440, the projection of the first suction nozzle and the tray support 611 in the first tray transfer module 610 in the third direction at least partially overlap, so that the first suction nozzle can suck the motor chip assembly to be assembled from the tray lifted by the first tray transfer module 610; after the first suction nozzle sucks the motor chip assembly, it drives the motor chip assembly to move above the first automatic optical inspection module 410 to adjust the attitude of the motor chip assembly, so that the lower bottom surface of the motor chip assembly is substantially 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] When the tray support 612 in the second tray transfer module 620 is at a certain position of the moving shaft 613 and the second suction nozzle is at the fourth position on the slide rail module 440, the projection of the second suction nozzle and the tray support 611 in the second tray transfer module 620 in the third direction at least partially overlap, so that the second suction nozzle can suck the lens from the tray support 611; the second suction nozzle can suck the lens from the first tray lifted by the second tray transfer module 620 and drive the lens to move above the second automatic optical inspection module 420 to perform AOI inspection (such as stain inspection) 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 attitude of the lens 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 substantially flush.

[0116] In some embodiments, the above camera module assembly device includes multiple groups of active alignment structures 200. The dispensing structure 300 includes multiple dispensing parts 320 and multiple glue cleaning parts. The gantry loading and unloading structure 400 includes multiple exposure lamp modules 430. That is to say, the camera module assembly device includes multiple production lines for active alignment, dispensing, and exposure. It should be understood that since the time required for loading and unloading on the production line is less than the time required for alignment, dispensing, and exposure, by setting multiple production lines for active alignment, dispensing, and exposure, the loading and unloading structures (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 device includes two production lines for active alignment, dispensing, and exposure. These two production lines are arranged in parallel. The slide rail module 440 divides the two production lines into a loading and unloading + exposure area, an active alignment area, and a dispensing area in sequence. 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 dispensing structure 300 is located in the dispensing area, so that some steps can be carried out synchronously to improve the assembly efficiency.

[0118] Please refer to Figure 12 As shown, the present application provides a camera module assembly method. The camera module assembly method is applied to the camera module assembly device described above. The camera module assembly device includes a first multi-dimensional correction module, a second multi-dimensional correction module, and a moving platform. The first multi-dimensional correction module and the second multi-dimensional correction module are arranged on the moving platform. The first multi-dimensional correction module includes a lens nozzle, and the lens 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. Absorb 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 on the second multi-dimensional correction module;

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

[0122] S600. After the active alignment of the lens and the motor chip assembly, keep the relative position between the lens and the motor chip assembly unchanged, and move the first multi-dimensional correction module and the second multi-dimensional correction module to the dispensing station through the moving platform;

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

[0124] Specifically, after the camera module assembly device sucks a lens from the lens transfer module through the lens suction nozzle of the first multi-dimensional correction module, it drives the first multi-dimensional correction module to move in the 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 device can move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station through the mover platform to perform active alignment between the lens and the motor chip assembly.

[0125] It can be understood that moving the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station through the mover platform can occur before step S200 or step S400 or step S500. For example, the camera module assembly device 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; or, the camera module assembly device can execute step S200, move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station, and then execute step S400. Or, the camera module assembly device can execute step S400, 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 mover 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 mover platform drives the two multi-dimensional correction modules to move to the dispensing position together, which can keep the relative positions of the lens and the motor chip assembly unchanged during the movement, avoid the position deviation 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 the multiple second openings of the lens suction nozzle enables the lens suction nozzle to always suck the lens during active alignment and dispensing processes, which can optimize the connection of the active alignment and dispensing fixing processes, avoid the position deviation of the lens during active alignment and dispensing, and further reduce the assembly tolerance of the camera module.

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

[0129] Of course, in some other embodiments, other common fixing methods can also be used to fix the lens and the motor, and the present application will not list them one by one here.

[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, so as to ensure that the relative positions of the lens and the motor chip assembly after active alignment will not change.

[0131] In some embodiments, in step S600, after the mover 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 in the third direction (i.e., the vertical direction).

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

[0133] S510. Move the first multi-dimensional correction module and the second multi-dimensional correction module to the active alignment station through the mover platform;

[0134] S520. At the active alignment station, adjust the position and / or angle of the lens through the first multi-dimensional correction module, or adjust the position and / or angle of the motor chip assembly through the second multi-dimensional correction module, so that the image of the target board obtained by the motor chip assembly meets the preset requirements. Among them, at the active alignment station, the lens, the motor chip assembly, and the target board 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, which means moving to the position corresponding to the target board and the teleconverter, that is, the positions corresponding to the target board, the teleconverter, the lens, and the motor chip assembly in 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 best calibration method can be selected according to the product characteristics, so as to match diverse production requirements. For example, when the chip quality is relatively large, the lens can be adjusted, and vice versa, to optimize energy consumption and structural life, etc.

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

[0138] It should be understood that dust, scratches, bubbles or coating defects on the lens surface may cause fixed dark spots, blurred areas or abnormal reflections in the image, that is, bad points are generated. By detecting the optical defects of the lens in advance before the lens and the motor chip assembly are fixed, the losses caused by disassembling and scrapping due to optical problems after the subsequent camera module is assembled can be avoided, and the defect rate can be reduced.

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

[0140] S300a1. Actively align the lens and the normally-on pattern chip to obtain the first positional relationship between the lens and the normally-on pattern chip;

[0141] S300a2. Use the vision laser module to calibrate the coordinates and tilt angles of the photosensitive surface and the reference bottom surface to obtain the second positional relationship;

[0142] S300a3. Based on the first positional relationship and the second positional relationship, determine the third positional relationship between the lens and the motor chip assembly, where the second positional relationship includes the relative coordinate relationship and the relative tilt angle between the photosensitive surface and the reference bottom surface of the normally-on pattern chip.

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

[0144] It should be noted that in this application, the sequence between step S300a1 and S300a2 is not limited, as long as it is ensured that both are before step S300a3, that is, first obtain the first positional relationship and the second positional relationship, and then through step S300a3, determine the third positional relationship based on the first positional relationship and the second positional relationship.

[0145] Specifically, the above-mentioned normally-on pattern chip is a sensor capable of continuously capturing patterns, which can maintain the "normally-on" state under extremely low power consumption to respond to visual signals in real time. In step S500, the calibration plate, the lens and the normally-on pattern chip are distributed along the third direction. Using the normally-on pattern chip in the energized state as the optical reference, the calibration plate projects a pattern, and the light passes through the lens and forms an image on the normally-on pattern chip. The image data captured by the normally-on pattern chip is used to reverse the pose deviation between the lens and the chip.

[0146] In this application, a normally open pattern chip is used as a reference for the transmission of the positional relationship, so as to determine the position and angle (i.e., the third positional relationship) of the lens group when it is inserted into the motor chip assembly through the transmission chain of the positional relationship (the first positional relationship - the second positional relationship - the third positional relationship), so that the pose of the lens is determined before insertion, reducing the adjustment margin reserved within the motor chip assembly, which is conducive to the miniaturization of the motor.

[0147] The first positional relationship (lens - normally open pattern chip) is dynamically obtained through active alignment optical detection;

[0148] The second positional relationship (normally open pattern chip - motor fixture) is obtained through pre - calibration by a vision laser module, and the multi - dimensional correction parameter relationship between the surface of the normally open pattern chip and the motor sinking surface (motor chip assembly) is recorded;

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

[0150] Further, please refer to Figure 15 As shown, in some embodiments, the first positional relationship includes the first coordinate information and the first angle information of the lens after the active alignment of the lens and the normally open pattern chip, the second positional relationship includes the relative coordinate information and the relative tilt angle between the photosensitive surface and the reference bottom surface, and the third positional relationship includes the second coordinate information and the second angle information of the lens when the lens is assembled into the motor chip assembly; Step S400 includes:

[0151] S410. Keep the position and tilt angle of the reference bottom surface unchanged, and adjust the horizontal position of the lens according to the second coordinate information so that the lens and the motor chip assembly are 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 to assemble the lens into the motor chip assembly.

[0153] When the image captured on the normally open pattern 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 pattern chip, and obtain the first coordinate information and the 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 may include the coordinate offset and angular offset between the reference bottom surface of the motor fixture and the photosensitive surface (i.e., the upper surface) of the normally open image chip. The second positional relationship can be expressed as (ΔX, ΔY, ΔZ, Δθx, Δθy, Δθz).

[0155] The above-mentioned second coordinate information can be obtained from the first coordinate information and the coordinate offset. For example, the second coordinate information is 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 angular information can be obtained from the first angular information and the angular offset. For example, the second angular information is obtained by adding the first angular information and the angular offset, and the second angular information can be expressed as (θx1+Δθx, θy1+Δθy, θz1+Δθz).

[0156] After the camera module assembly device obtains the second coordinate information and the second angular 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 device first adjusts the horizontal position of the lens according to the second coordinate information so that the lens and the motor chip assembly are in the same vertical direction, that is, the camera module assembly device moves the lens above the motor chip assembly through the first multi-dimensional correction module. At this time, the coordinates of the lens on the XY axis satisfy (X1+ΔX, Y1+ΔY). The camera module can first adjust the angular information of the lens and then adjust the vertical position of the lens.

[0158] Exemplarily, in order to avoid the lens and the motor chip assembly colliding with each other when adjusting the horizontal position of the lens, the camera module assembly device 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] Exemplarily again, in order to avoid the lens and the motor chip assembly 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 (i.e., 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 the 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, and when the camera module assembly device 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 device first adjusts the horizontal position of the lens, and then adjusts the vertical position and angle of the lens, which can avoid the collision between the lens and the motor chip assembly during assembly. At the same time, the lens is assembled to the motor chip assembly with determined coordinate information and angle information, which allows a smaller space to be reserved in the motor chip assembly for assembling the lens. The lens and the motor chip assembly can be assembled with a smaller gap, which is beneficial to the miniaturization of the motor chip assembly and the camera module.

[0161] It should be understood that by using the normally open pattern chip as an intermediate reference, the error sources of lens optical calibration and mechanical assembly of the motor chip assembly can also be separated, avoiding the secondary deviation caused by the internal adjustment of the motor chip assembly in the traditional method and improving the accuracy of active calibration.

[0162] In addition, since the precise relative position (i.e., the third positional relationship) between the lens and the motor chip assembly is first determined in this application, and then the assembly is directly performed according to the data of the third positional relationship, the position offset caused by the active alignment adjustment in the traditional method can be suppressed, and the uncertainty brought by dynamic adjustment can be reduced. Further, in some embodiments, step S400 includes adjusting the position and / or angle of the lens through the first multi-dimensional correction module, or adjusting the position and / or angle of the normally open pattern chip through the second multi-dimensional correction module, so that the image of the target board obtained by the normally open pattern chip meets the preset requirements. That is to say, step S400 can complete the active alignment by adjusting the first multi-dimensional correction module or the second multi-dimensional correction module.

[0163] Specifically, the active alignment is completed by adjusting the lens, that is, the position and inclination angle of the lens are adjusted through the first multi-dimensional correction module, and the target board image is obtained by using the normally open pattern chip. When the image obtained by the normally open pattern chip meets the requirements, the position and inclination angle of the lens and the normally open pattern chip are determined; the active alignment is completed by adjusting the normally open pattern chip, that is, the position and inclination angle of the normally open pattern chip are adjusted through the second multi-dimensional correction module, and the target board image is obtained by using the normally open pattern chip. When the image obtained by the chip meets the requirements, the position and inclination angle of the lens and the chip are determined.

[0164] Of course, in some other embodiments, the lens and the normally open pattern chip can also be adjusted simultaneously, that is, the active alignment is completed by adjusting the first multi-dimensional correction module and the second multi-dimensional correction module simultaneously, and the specific adjustment process will not be elaborated 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. Adjust the attitude of the lens with reference to the reference bottom surface of the reticle or the motor fixture, so that the horizontal reference plane of the lens is flush with the reticle or the reference bottom surface. Herein, the reference bottom surface is used to place the motor chip assembly, the horizontal reference plane of the lens is perpendicular to the optical axis of the lens, and the reticle is used for active alignment between the lens and the motor chip assembly.

[0167] It should be understood that by adjusting the horizontal reference plane of the lens, the initial pose error of the lens can be eliminated, ensuring that it is parallel to the horizontal plane of the reticle 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 is worth mentioning that in the present application, different adjustment methods can be selected according to actual needs. That is to say, the lens leveling can be performed with reference to the reference bottom surface of the reticle or the motor fixture according to actual needs. In addition, during the actual production process, step S300b can be executed once after multiple rounds of assembly steps to eliminate the error amount accumulated during the production process and ensure the 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 an automatic optical inspection on the lens.

[0171] Specifically, in step S100, the camera module assembly device can suck the lens from the first 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 an automatic optical inspection on the lens.

[0172] The automatic optical inspection includes but is not limited to detecting stains and scratches on the lens surface. If the diameter of the stain or scratch on the lens surface is greater than or equal to a certain threshold (such as 20 micrometers (μm)), it is confirmed that the automatic optical inspection of the lens fails. The lens can be sucked through the fourth suction nozzle and placed in the waste tray. If the stain on the lens surface is less than the threshold, it is confirmed that the automatic optical inspection of the lens passes, and the lens is placed on the lens transfer module for the subsequent lens assembly process.

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

[0174] In addition, in some embodiments, before step S200, the method further includes: obtaining the position of the lens in the lens transfer module through the vision module. Obtaining the position parameters of the lens through the vision module facilitates the subsequent suction of the lens by the lens suction nozzle from the lens transfer module, reduces the possibility of suction failure, improves the automation stability, and at the same time reduces the error amount introduced by the suction deviation, further improving the 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. Moving the first multi-dimensional correction module and the second multi-dimensional correction module to the exposure station through the mover platform;

[0177] S820. On the exposure station, curing the glue in the camera module through the exposure lamp, wherein the first opening and the plurality of second openings provide optical path channels for the exposure lamp;

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

[0179] Specifically, after dispensing, the camera module assembly device moves the first multi-dimensional correction module and the second multi-dimensional correction module to the exposure station through the mover platform, and cures the glue in the camera module by using the exposure lamp module on the gantry loading and unloading structure. After the exposure is completed, the lens suction nozzle releases the lens, and the third suction nozzle of the gantry loading and unloading structure sucks the camera module from the motor fixture and moves the camera module above the first automatic optical inspection module to perform automatic optical inspection on the camera module. The automatic optical inspection includes but is not limited to detecting whether there is residual fluorescent glue on the camera module and whether there are stains on the surface, etc.

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

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

[0182] S920. Detecting the imaging quality of the camera module by using a reticle.

[0183] In this application, before the camera module is unloaded, the imaging quality of the camera module can be detected by using a reticle and a teleconverter. Specifically, the mover platform moves the second multi-dimensional correction module to the active alignment station. At this time, the camera module, the reticle, and the teleconverter are in the same vertical direction. The image of the reticle is obtained through the camera module, and the imaging quality of the camera module is detected by the image of the reticle obtained through the camera module.

[0184] Further, in some embodiments, during the process of curing the glue in the motor chip assembly by the exposure lamp, the camera module assembly device can pick up the next lens from the first tray, that is to say, some steps in the two consecutive rounds of assembly processes can be parallelized.

[0185] It should be understood that by adopting a multi-step parallel design, parallelizing the exposure curing with the lens feeding, and parallelizing the motor feeding with the lens transfer, the idle and waiting time of the device can be reduced, the production rhythm can be optimized, and the production efficiency can be improved. Of course, on the premise that the device permits, other steps in the same round or different rounds of assembly processes can also be parallelized to optimize the production efficiency, and the present application does not list them one by one here.

[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] Placing the motor chip assembly into the motor fixture.

[0189] The vision module can be the first automatic optical detection module described above, or other modules with vision positioning functions provided on the gantry loading and unloading structure. Adjusting the position and posture of the motor chip assembly through the visual feedback of the vision module can ensure that the lower surface of the motor chip assembly matches the reference bottom surface (i.e., the contact surface) of the motor fixture after insertion, improve the consistency of the reference surface for subsequent active alignment, and thus reduce the mechanical assembly error.

[0190] It is worth mentioning that the vision module can not only be used for visual positioning of the motor chip assembly to be assembled, but also for automatic optical detection of the assembled camera module, with high versatility and effectively reducing the equipment cost.

[0191] In addition, in the present application, the sequence relationship between the step of "adjusting the posture of the motor chip assembly through the vision module" and step S100 is not limited, as long as both are before step S200.

[0192] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification. The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
