Description

Camera module assembling method and assembling equipment

Technical Field

The invention relates to the field of camera modules, in particular to a camera module assembling method and assembling equipment.

Background

The calibration equipment of the module of making a video recording is an important link in the module of making a video recording makes a video recording, and it is influencing the imaging quality of whole module of making a video recording, is also influencing the production efficiency of product.

The existing assembly process of the camera module is that after the assembly of the camera module components is completed, for example, after the assembly of the lens and the photosensitive component is completed, the whole lens and the photosensitive component are actively calibrated by a calibration device, and the whole calibration process is completed on one station.

In recent years, an adjustable lens, such as a split adjustable lens composed of a plurality of lens units, and a lens adjustable lens in which a lens can be adjusted after being assembled to a lens barrel, have become an important part in lens development. The camera module formed by assembling the adjustable lens comprises two calibration processes, wherein one is the calibration of the adjustable lens, and the other is the calibration of the adjustable lens and the photosensitive part, and during the calibration, the lens is actively calibrated firstly, and then the integral camera module formed by the lens and the photosensitive part is actively calibrated.

More specifically, the conventional calibration process includes fixing the adjustable lens and a photosensitive component standard member to a calibration device, adjusting and calibrating the adjustable lens by the calibration device, removing the photosensitive component standard member, placing the photosensitive component to be assembled, and performing module calibration on the adjustable lens and the photosensitive component.

The inventors have found that there are several aspects to be improved with existing calibration assembly equipment and calibration assembly methods.

First, lens calibration and module calibration are concentrated on one device, and the calibration method of lens calibration and module calibration is different from the required components, so that more different components are concentrated on one device, and when some components are used and other devices are in an idle state, for example, when a lens is calibrated, the module calibration components are in an idle device.

Secondly, during calibration, the photosensitive component standard part needs to be placed firstly, then the photosensitive component standard part is moved away, and then the photosensitive component to be assembled is placed, so that the operation process is complicated for many times.

Overall, the centralized, single-station alignment assembly method results in a low assembly efficiency of the whole module.

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 6, there is provided a camera module assembling apparatus according to a first embodiment of the present invention, which is used for calibrating and assembling a camera module, and further, is used for calibrating a camera module assembled by an adjustable lens 10.

The camera module comprises an adjustable lens 10 and a photosensitive assembly 20, that is, the camera module assembling equipment is used for assembling the adjustable lens 10 and the photosensitive assembly 20 in a calibration manner to form the camera module. By way of example and not limitation, the photosensitive assembly 20 includes a photosensitive chip for performing a photosensitive function and a circuit board, and the photosensitive chip is electrically connected to the circuit board and transmits photosensitive information to the circuit board.

In this embodiment of the present invention, the camera module assembling apparatus is used to align and assemble a camera module formed by a split-type adjustable lens 10. That is, the adjustable lens 10 of the image pickup module is a split adjustable lens 10.

In this embodiment of the present invention, the split adjustable lens 10 includes an adjustment lens unit 11 and a fixed lens unit 12, and the adjustment lens unit 11 and the fixed lens unit 12 are stacked to form a complete optical lens. That is, the adjustable lens 10 has a complete optical system, i.e., an optical system that can perform imaging, and the adjustment lens unit 11 and the fixed lens unit 12 each constitute a part of the complete optical system. In other words, the adjustment lens unit 11 and the fixed lens unit 12 each constitute an incomplete optical system, that is, the adjustment lens unit 11 alone or the fixed lens unit 12 alone cannot perform imaging. The adjustable lens unit 11 and the fixed lens unit 12 can be assembled to form the adjustable lens 10 in a calibrated manner, for example, when the split adjustable lens 10 is assembled, the relative positions of the adjustable lens unit 11 and the fixed lens unit 12 can be adjusted to calibrate the adjustable lens 10, and thus the adjustable lens unit 11 and the fixed lens unit 12 are fixed to form the determined adjustable lens 10.

Further, the adjusting lens unit 11 and the fixed lens unit 12 each include a lens barrel and at least one lens, and the lens is assembled to the lens barrel to form a lens unit. It should be noted that the calibration of the adjustable lens 10 refers to the adjustment after the lenses of the adjustable lens unit 11 and the fixed lens unit 12 are respectively mounted in the corresponding lens barrels to form the lens units, and is not the adjustment when the lenses are assembled in the lens barrels. That is, in this embodiment of the present invention, the calibration of the adjustable lens 10 refers to the calibration assembly between the entire lens units. In an embodiment of the present invention, the adjusting lens unit 11 or the fixed lens unit 12 may have no lens barrel, that is, the adjusting lens unit 11 or the fixed lens unit 12 may be a single lens or lenses assembled with each other.

The camera module assembling apparatus includes a lens assembling station 110, a module assembling station 130 and a transferring device 120. The lens assembling station 110 is used for calibrating and assembling the adjustable lens 10, and the module assembling station 130 is used for calibrating and assembling the whole camera module. The transferring device 120 is used for transferring the adjustable lens 10 after the lens assembling station 110 is aligned and assembled to the module assembling station 130. That is, in the process of batch calibration and assembly of the camera module, the lens assembly station 110 separately calibrates and assembles the unaligned adjustable lens 10, the calibrated adjustable lens 10 is transferred to the module assembly station 130 by the transfer device 120, the calibrated adjustable lens 10 and the photosensitive assembly 20 to be assembled are further calibrated and assembled by the module assembly station 130, and finally, the camera module is assembled into an integral camera module.

In this embodiment of the present invention, the lens assembling station 110 is used to align and assemble the adjustable lens 10 in which the separate adjusting lens unit 11 and the fixed lens unit 12 are integrated. The module assembling station 130 is used for actively calibrating the independent split adjustable lens 10 and the independent photosensitive assembly 20 to form an integral camera module. In other words, the lens assembly station 110 performs the calibration assembly on the individual adjustable lens 10 that is not calibrated and assembled, and the module assembly station 130 performs the calibration on the calibrated individual adjustable lens 10 and the photosensitive component. That is, active calibration at the lens assembly station 110 is intended to achieve better quality lenses, while active calibration at the module assembly station 130 is intended to achieve better quality overall camera modules.

That is, the lens alignment and assembly process is continuously performed at the lens assembly station 110, and the module assembly process is continuously performed at the module assembly station 130, that is, the lens assembly process and the module assembly process are separated from each other and can be independently performed. In other words, the lens assembly process is performed at the lens assembly station 110 alone, and the module assembly process is performed at the module assembly station 130 alone, rather than being performed in a mixed manner, so that the division of the lens assembly station 110 and the module assembly station 130 is more precise and targeted.

It is worth mentioning that, in the existing assembly mode, the lens assembly process and the module assembly process are performed at the same station, that is, the lens assembly process and the module assembly process are mixed with each other, that is, when assembling a camera module, the calibration lens is assembled first, and then the camera module is assembled at the same station, so that the lens assembly process and the module assembly process are mutually limited, and when the camera module is produced in batches, the production efficiency is low. In the embodiment of the present invention, the lens assembling process and the module assembling process are separately performed at two stations, that is, the lens assembling process and the module assembling process are independently performed, and the assembling time and the assembling sequence are not limited to each other. That is, the lens assembling process and the module assembling process may be performed simultaneously or sequentially without being limited by a single assembling station, so that the assembling efficiency of each station is greatly improved, the assembling efficiency of the adjustable lens 10 and the assembling efficiency of the module are both improved, and the production efficiency of the mass-produced camera modules is improved.

Further, referring to fig. 2 and 3, the lens assembly station 110 includes a lens holder assembly 1101 and a standard holder 1102, wherein the lens holder assembly 1101 is used for adjusting and holding the adjustable lens 10. The standard holder 1102 is used to hold a photosensitive assembly standard 40. That is, when the adjustable lens 10 is assembled by alignment, the adjustable lens 10 that is not aligned is mounted on the lens holder 1101, and the photosensitive-assembly standard 40 is mounted on the standard holder 1102.

The standard holder 1102 is used to hold the photosensitive assembly standard 40 aligned in cooperation with the lens holder assembly 1101. That is to say, when the adjustable lens 10 is assembled and calibrated, the photosensitive assembly standard 40 cooperates with the adjustable lens 10 to perform imaging, and then the adjustable lens 10 is adjusted according to the imaging result. It should be noted that the photosensitive assembly module 40 may include a standard circuit board and a standard photosensitive chip to cooperate with the adjustable lens 10 to perform imaging. The photosensitive assembly standard 40 may also include other components for imaging, such as filters. The photosensitive device standard 40 may be a photosensitive device pre-selected to meet a predetermined standard, or a photosensitive device with a good flatness of a selected circuit board and the standard photosensitive chip, so as to provide a good calibration basis for the calibration of the adjustable lens 10, and it can be understood by those skilled in the art that the photosensitive device standard 40 is not limited to an absolute standard.

In this embodiment of the present invention, the lens holding assembly 1101 includes an adjustment lens holder 11011 and a fixed lens holder 11012, the adjustment lens holder 11011 holding the adjustment lens unit 11, and the fixed lens holder 11012 holding the fixed lens unit 12. Preferably, the adjustment lens holder 11011 is used to clamp the adjustment lens unit 11 to adjust the adjustment lens unit 11. The fixed lens holder 11012 is used to hold the fixed lens unit 12 to fix the fixed lens unit 12 in cooperation with adjustment of the adjustment lens unit 11.

It is worth mentioning that in this embodiment of the present invention, the assembly apparatus is exemplified by the split adjustable lens 10 composed of two lens units, i.e., the adjusting lens unit 11 and the fixed lens unit 12, but in other embodiments of the present invention, the calibration assembly apparatus may also be used to calibrate and assemble the adjustable lens 10 composed of more lens units.

Further, referring to fig. 2 and 3, the lens assembling station 110 includes a first target 1103 and a first dispensing fixing member 1104, the first target 1103 is used for cooperating with the adjustable lens 10 to perform imaging, and the first dispensing fixing member 1104 is used for dispensing and fixing the calibrated adjustable lens 10.

When the adjustable lens 10 is assembled and calibrated, the complete optical system formed by the adjustable lens unit 11 and the fixed lens unit 12 obtains the image information of the first target 1103 and performs imaging by using the photosensitive assembly standard, the adjustable lens holder 11011 adjusts the adjustable lens unit 11 according to the imaging result of the photosensitive assembly standard, and after the imaging of the adjustable lens 10 meets the predetermined requirement, the first dispensing fixing member 1104 performs dispensing fixing on the adjustable lens unit 11 and the fixed lens unit 12.

In this embodiment of the present invention, the adjustment amount is obtained by capturing a reticle image for calibration, but in other embodiments of the present invention, other observation elements may be used for calibration, such as laser height measurement and machine vision, for example, the lens assembly station 110 may be without the first reticle 1103, and it should be understood by those skilled in the art that the manner of obtaining the adjustment amount by the lens assembly station 110 is not limited by the present invention.

Preferably, in an embodiment of the present invention, the adjustable lens holder 11011 of the lens assembling station 110 clamps and adjusts the adjustable lens unit 11, the fixed lens holder 11012 clamps and fixes the fixed lens unit 12, the standard holder 1102 fixes the photosensitive assembly standard 40, the adjustable lens unit 11 and the fixed lens unit 12 form an imaging system with the photosensitive assembly standard 40, and the position of the adjustable lens unit 11 relative to the fixed lens unit 12 is adjusted by the measured resolving power of the imaging system to calibrate the optical system of the adjustable lens 10, for example, but not limited to, the adjustment is performed so that the axes of the adjustable lens unit 11 and the fixed lens unit 12 are consistent, so that the measured resolving power of the complete optical system of the adjustable lens 10 reaches a standard.

Preferably, in an embodiment of the present invention, the adjusting lens holder 11011 obtains the amount of lens adjustment to be performed based on aberration according to the first target 1103 information acquired by the adjustable lens 10 and the photosensitive assembly standard 40. The amount to be adjusted may include six-axis adjustment in the horizontal, oblique, and optical axis directions. That is, the adjustment lens holder 11011 can perform six-axis adjustment in the horizontal, oblique, and optical axis directions on the entire adjustment lens unit 11. In this way, even if the positions of the respective lenses and lens barrels of the adjustment lens unit 11 and the fixed lens unit 12 have been fixed, the optical system of the entire adjustable lens 10 constituted by the adjustment lens unit 11 and the fixed lens unit 12 can still be calibrated, i.e., so that the overall imaging quality of the adjustable lens 10 is improved. That is, the lens assembling station 110 mainly adjusts the aberration of the adjustable lens 10, including field region, astigmatism, spherical aberration, coma aberration, distortion, and the like of the lens. In other words, the imaging quality factor caused by the optical system is mainly calibrated at the lens calibration station, so that the adjustable lens 10 is mainly calibrated, not the photosensitive assembly standard. Of course, the photosensitive assembly standard may be adjusted in some cases, in an embodiment of the present invention, for example, during the first calibration, the photosensitive assembly standard 40 may be adjusted in a tilt manner with respect to the adjustable lens 10 by the standard holder 1102 to adjust and match the adjustment of the adjustable lens 10 to calibrate the whole optical system, and in an embodiment of the present invention, the photosensitive assembly standard 40 may be adjusted in the optical axis direction by the standard holder 1102 when acquiring the MTF/SFR curve. The adjustment process may be a calibration of the device at initial use. In other words, the photosensitive assembly standards 40 may be adjusted by the standard holder 1102 at the time of initial calibration or acquisition of MTF/SFR curves. In one embodiment of the present invention, before the adjustable lens 10 is calibrated, the lens assembly station, such as the photosensitive assembly standard 40, may be calibrated, so that the photosensitive assembly standard remains flat and provides a good calibration condition. In calibrating the lens assembly station, a standard lens, i.e., a lens with good imaging performance selected in advance, may be held by the lens holder 1101, the standard lens and the photosensitive-component module 40 constitute an imaging system, and the inclination and/or the position along the optical axis of the photosensitive-component module 40 is adjusted by the module holder 1102, thereby calibrating the lens assembly station 110 and/or the photosensitive-component module 40.

It is also worth mentioning that the photosensitive assembly standards 40 may not be adjusted at the time of subsequent calibrations after being adjusted at the time of first calibration, and the adjusted photosensitive assembly standards 40 may be always maintained in the standard holder 1102 without being replaced. That is, the photosensitive assembly standard 40 can be matched with the calibration process of a plurality of adjustable lenses 10, so that the calibration of the adjustable lenses 10 is consistent, in other words, has the same calibration basis.

Referring to fig. 4 and 5, the module assembling station 130 includes a lens holder 1301 and a photosensitive assembly holder 1302. The lens holding assembly 1101 is used for adjusting and holding the adjustable lens 10 after being calibrated. The photosensitive-unit holder 1302 is used to adjust and hold the photosensitive unit 20. That is, the lens holder 1301 is used to adjust and hold the adjustable lens 10 as a whole after calibration, and the photosensitive member holder 1302 is used to adjust and hold the photosensitive member 20 to be assembled to constitute a camera module. When the camera module is calibrated and assembled, the adjustable lens 10 after calibration is mounted on the lens holder 1301, the photosensitive assembly 20 to be assembled is mounted on the photosensitive assembly holder 1302, and the adjustable lens 10 and/or the photosensitive assembly 20 are adjusted by the lens holder 1101 and/or the photosensitive assembly holder 1302, so that the camera module is actively calibrated. And the calibrated adjustable lens and the photosensitive assembly form a module imaging system, and active calibration is carried out according to the imaging quality of the module imaging system during calibration.

Further, the module assembling station 130 includes a second target 1303 and a second dispensing fixture 1304, where the second target 1303 is used for cooperating with the adjustable lens 10 and the photosensitive element 20 to form an image, and the second dispensing fixture 1304 is used for dispensing and fixing the calibrated adjustable lens 10 and the calibrated photosensitive element 20.

When the camera module is calibrated and assembled, the calibrated adjustable lens 10 obtains the image information of the second reticle 1303, and performs photosensitive imaging through the photosensitive assembly 20, the lens holder 1301 and the photosensitive assembly holder 1302 adjust the adjustable lens 10 and/or the photosensitive assembly 20 according to the imaging result of the photosensitive assembly 20, and after the imaging of the camera module meets the predetermined requirement, the second dispensing fixing part 1304 performs dispensing fixing on the adjustable lens 10 and the photosensitive assembly 20.

In this embodiment of the present invention, the adjustment amount is obtained by capturing the reticle image for calibration, but in other embodiments of the present invention, other observation elements may be used for calibration, such as laser height measurement and machine vision, for example, the module assembling station 130 may be without the second reticle 1303, and it should be understood by those skilled in the art that the method for obtaining the adjustment amount by the module assembling station 130 is not limited by the present invention.

Preferably, in an embodiment of the present invention, the lens holder 1301 of the module assembling station 130 clamps and adjusts the adjustable lens 10 after being calibrated and fixed, the photosensitive assembly holder 1302 fixes the photosensitive assembly 20, the adjustable lens 10 and the photosensitive assembly 20 form an imaging system, and the position of the adjustable lens 10 relative to the photosensitive assembly 20 is adjusted by the measured resolution of the imaging system to calibrate the camera module, for example, but not limited to, adjusting to make the centers of the adjustable lens 10 and the photosensitive assembly 20 adjusted to be consistent, such as the center of a photosensitive chip, and adjusting to make the image plane of the adjustable lens 10 and the image plane of the photosensitive chip of the photosensitive assembly 20 consistent, so that the measured resolution of the camera module reaches a standard.

Preferably, in an embodiment of the present invention, the lens holder 1301 obtains the amount of lens adjustment to be performed based on the resolution according to the second target 1303 information acquired by the adjustable lens 10 and the photosensitive assembly 20. The amount to be adjusted may include six-axis adjustment in the horizontal, oblique, and optical axis directions. That is, the lens holder 1301 can perform the six-axis adjustment in the horizontal, oblique, and optical axis directions on the entire adjustable lens 10. In this way, even if the positions of the lenses and the lens barrel of the adjustable lens 10 have been fixed, the imaging system of the entire camera module formed by the adjustable lens 10 and the photosensitive assembly 20 can still be calibrated, i.e., the imaging quality of the entire camera module is improved.

That is, the lens assembling station 110 and the module assembling station 130 configure components corresponding to separate assembling processes, respectively.

Further, referring to fig. 6, the camera module assembling apparatus may further include a light source 140, and the light source 140 provides imaging light for the lens assembling station 110 and the module assembling station 130. That is, the lens assembling station 110 and the module assembling station 130 share one light source 140, thereby reducing the arrangement of components. Of course, in other embodiments of the present invention, the lens assembly station 110 and the module assembly station 130 may be respectively configured with the light source 140 so as to provide the light irradiation condition separately.

In an embodiment of the present invention, the lens assembly station 110, the transfer device 120, and the module assembly station 130 may be integrally provided, that is, the lens assembly station 110, the transfer device 120, and the module assembly station 130 are configured in one apparatus as a whole. Of course, the lens assembling station 110, the transferring device 120 and the module assembling station 130 may also be separately arranged, that is, a plurality of independent devices respectively form the lens assembling station 110, the transferring device 120 and the module assembling station 130, so that the lens assembling process and the module assembling process are completely independent, and the influence of the vibration generated when the lens assembling station 110 and the module assembling station 130 respectively work on each other is reduced. It should be understood by those skilled in the art that the arrangement of the lens assembling station 110, the transferring device 120 and the module assembling station 130 thereof is not a limitation of the present invention.

Preferably, in an embodiment of the present invention, the transfer device 120 is an automatic loading and unloading apparatus, that is, the transfer device 120 is capable of assembling materials and taking out finished products for the lens assembling station 110 and the module assembling station 130. In other words, the transfer device 120 can transfer the semi-finished product of the adjustable lens 10, load the adjustable lens unit 11 and the fixed lens unit 12 for assembling the adjustable lens 10 to the lens assembly station 110, and assemble the module assembly station 130 to complete the taking out of the finished product of the camera module, so that the lens assembly station 110 and the module assembly station 130 are in a continuous automatic assembly process, and the active calibration and fixing processes of the adjustable lens 10 and the camera module are connected with each other, thereby reducing intermediate steps and avoiding a pollution problem possibly caused by intermediate links.

Fig. 7 is a schematic diagram of a modified embodiment of the image pickup module assembling apparatus according to the first embodiment of the present invention. In this embodiment of the present invention, the camera module assembling apparatus includes at least two of the lens assembling stations 110, one of the transfer devices 120, and one of the module assembling stations 130. That is, the plurality of lens assembling stations 110 are associated with one module assembling station 130 to perform an assembling work of the camera module, so that the alignment assembling efficiency of the adjustable lens 10 of the lens assembling station 110 is matched with the alignment assembling efficiency of the module assembling station 130. In other words, the lens assembling station 110 and the module assembling station 130 can be in a continuous assembling process, so that the idle state of the equipment is reduced, and the efficiency of mass production of the camera modules is further improved.

It should be noted that, in the process of calibrating the adjustable lens 10, the relative position between the lens units and the photosensitive component need to be adjusted, and in the process of assembling the module, the relative position between the whole adjustable lens 10 and the photosensitive component 20 needs to be adjusted, so the lens assembling duration of the lens assembling station 10 is longer than the module assembling duration of the module assembling station 130, and the assembling efficiency is lower, so the lens assembling station 110 and the module assembling station 130 can both continuously work through the cooperation of the plurality of lens assembling stations 110 and the module assembling station 130, and the overall efficiency of the camera module assembling device is improved.

It is further noted that the number of the lens assembling stations 110 and the module assembling stations 130 can be configured according to the assembling efficiency, for example, when the assembling time of the lens assembling station 110 is twice that of the module assembling station 130, 2 lens assembling stations can be configured to cooperate with 1 module assembling station. On the contrary, when the assembly time of the module assembling station 130 is twice that of the lens assembling station 110, 1 lens assembling station 110 may be provided to cooperate with 2 module assembling stations 120, so that the overall assembly efficiency of the assembly apparatus is improved.

Fig. 11 is a schematic view illustrating an assembly process of a camera module lens according to a second embodiment of the invention. The camera module assembling equipment is used for calibrating and assembling a camera module, and further, the camera module assembling equipment is used for calibrating the camera module formed by assembling the lens adjustable lens 10A.

The camera module comprises an adjustable lens 10A and a photosensitive assembly 20A, and the camera module assembling equipment is used for calibrating and assembling the adjustable lens 10A and the photosensitive assembly 20A to form the camera module. That is, in this embodiment, the adjustable lens 10A of the camera module is a lens adjustable lens 10A. The camera module assembly equipment is used for calibrating and assembling the lens adjustable lens 10A and the photosensitive assembly 20A to form the camera module.

By way of example and not limitation, the photosensitive assembly 20A includes a photosensitive chip for performing a photosensitive function and a circuit board, and the photosensitive chip is electrically connected to the circuit board and transmits photosensitive information to the circuit board.

In this embodiment of the present invention, the lens-adjustable lens 10A includes at least an adjustable lens 13A, a fixed lens 14A and a carrying element 15A, and the adjustable lens 13A and the fixed lens 14A are disposed on the carrying element 15A along an optical path. Further, when assembling the lens-adjustable lens 10A, the fixed lens 14A is fixed to the bearing element 15A, and the adjustable lens 13A is adjustably disposed on the bearing element 15A. That is, after the adjustable lens 13A and the fixed lens 14A are assembled to the bearing element 15A, the position of the fixed lens 14A relative to the bearing element 15A is determined, and the position of the adjustable lens 13A relative to the bearing element 15A is movable. The adjustable lens 13A and the fixed lens 14A together constitute an optical system of the lens adjustable lens 10A. That is, in this embodiment of the present invention, the calibration of the lens adjustable lens 10A refers to the readjustment of the adjustable lens 13A after the adjustable lens 13A and the fixed lens 14A are assembled to the bearing element 15A. I.e. the alignment between the adjustable lens 13A and the fixed lens 14A.

Further, the bearing element 15A may be provided with an adjustment channel, which is located opposite to the adjustable lens 13A, so as to adjust the adjustable lens 13A through the adjustment channel.

The camera module assembling apparatus includes a lens assembling station 110A, a module assembling station 130A, and a transferring device 120A. The lens assembling station 110A is used for calibrating and assembling the lens adjustable lens 10A, and the module assembling station 130A is used for calibrating and assembling the whole camera module. The transfer device 120A is used for transferring the adjustable lens with lens 10A aligned and assembled at the lens assembly station 110A to the module assembly station 130A. That is, in the process of batch calibration and assembly of the camera module, the lens assembly station 110A separately calibrates and assembles the unaligned lens adjustable lens 10A, the calibrated lens adjustable lens 10A is transferred to the module assembly station 130A by the transfer device 120A, the calibrated lens adjustable lens 10A and the photosensitive component 20A to be assembled are further calibrated and assembled by the module assembly station 130A, and finally, an integral camera module is formed by assembly.

In this embodiment of the invention, the lens assembly station 110A is used to calibrate the device the adjustable lens 13A is not secured to the lens adjustable lens 10A of the carrier 15A. The module assembling station 130A is configured to actively calibrate the independent lens adjustable lens 10A and the photosensitive component 20A to form an integral camera module. In other words, the lens assembly station 110A performs the calibration assembly on the adjustable lens unit 10A which is not calibrated and assembled, and the module assembly station 130A performs the calibration on the adjustable lens unit 10A and the photosensitive assembly 20A after the calibration. That is, active calibration at the lens assembly station 110A is intended to obtain a better quality lens, while at the module assembly station 130A is intended to obtain a better quality overall camera module.

That is, the lens assembly process is continuously performed at the lens assembly station 110A, and the module assembly process is continuously performed at the module assembly station 130A, that is, the lens assembly process and the module assembly process are separated from each other and can be independently performed. In other words, the lens assembly process is performed at the lens assembly station 110A alone, and the module assembly process is performed at the module assembly station 130A alone, rather than being performed in a mixed manner, so that the division of the lens assembly station 110A and the module assembly station 130A is more precise and targeted.

It is worth mentioning that, in the existing assembly mode, the lens assembly process and the module assembly process are performed at the same station, that is, the lens assembly process and the module assembly process are mixed with each other, that is, when assembling a camera module, the calibration lens is assembled first, and then the camera module is assembled at the same station, so that the lens assembly process and the module assembly process are mutually limited, and when the camera module is produced in batches, the production efficiency is low. In the embodiment of the present invention, the lens assembling process and the module assembling process are performed separately at two stations, that is, the lens assembling process and the module assembling process are performed independently, and the assembling time and the assembling sequence are not limited to each other. Namely, the lens assembling process and the module assembling process can be carried out simultaneously or sequentially without being limited by a single assembling station, so that the assembling efficiency of each station is greatly improved, the adjustable lens assembling efficiency and the module assembling efficiency are improved, and the production efficiency of the mass-produced camera modules is improved.

Further, the lens assembly station 110A includes a lens holder 1101A and a standard holder 1102A, and the lens holder 1101A is used for adjusting and holding the adjustment lens.

It should be noted that the photosensitive assembly module 40A may include a standard circuit board and a standard photosensitive chip to cooperate with the lens-tunable-lens 10A to perform imaging. The photosensitive assembly 20A may also include other components for imaging, such as filters. The photosensitive component standard 40A may be a photosensitive component 20A which is pre-selected to meet a predetermined standard, or a photosensitive component 20A which has a selected circuit board and a standard photosensitive chip with good flatness, so as to provide a good calibration basis for the calibration of the lens adjustable lens 10A, and it can be understood by those skilled in the art that the photosensitive component standard 40A is not limited to an absolute standard.

In this embodiment of the present invention, the adjustment amount is obtained by capturing a reticle image for calibration, but in other embodiments of the present invention, other observation elements may be used for calibration, such as laser height measurement and machine vision, for example, the lens assembly station 110A may be without the first reticle 1103A, and it should be understood by those skilled in the art that the manner of obtaining the adjustment amount by the lens assembly station 110A is not limited by the present invention.

That is, the lens assembling station 110A mainly adjusts the aberration of the lens adjustable lens 10A, including the field region, astigmatism, spherical aberration, coma, distortion, and the like of the lens. In other words, the imaging quality factor caused by the optical system is mainly calibrated at the lens calibration station, so that the lens adjustable lens 10A is mainly calibrated, not the photosensitive assembly standard 40A. Of course, the photosensitive assembly standard 40A may be adjusted in some cases, in an embodiment of the present invention, for example, during the first calibration, the photosensitive assembly 20A may be adjusted in inclination relative to the adjustable lens unit 10A by the standard holder 1102A to adjust the adjustment of the adjustable lens unit 10A to calibrate the whole optical system, and in an embodiment of the present invention, the photosensitive assembly 20A may be adjusted in movement along the optical axis when the MTF/SFR curve is acquired.
