Description
Technical Field
The present invention relates generally to vehicle cameras and, more particularly, to a method of manufacturing an Advanced Driving Assistance System (ADAS) camera.
Background
With the development of the automatic driving industry, Advanced Driving Assistance Systems (ADAS) are widely used in the field of intelligent driving. Performance requirements for various functions of the ADAS (e.g., lane line identification, traffic sign identification, etc.) are also increasing. The demand for cameras, which are important sensors for implementing the ADAS function, is also increasing.
In the manufacturing process of the ADAS camera, a terminal block on a PCB (printed circuit board) needs to be fixedly assembled with a connector. However, during assembly, there may be positional deviation between the terminal block and the connector, which may cause stress in connecting the terminal block and the connector. The stress can affect the position of the image sensor on the PCB, thereby affecting the relative position between the image sensor and the lens and further affecting the imaging effect of the camera.
There is therefore a need for ADAS cameras and methods of making the same that provide higher pixel requirements and more stable performance requirements.
Disclosure of Invention
To solve the above technical problem, the present invention provides a method of manufacturing an Advanced Driver Assistance System (ADAS) camera, the camera including a camera front end assembly, a rear cover and a connector, the camera front end assembly including a lens, a lens mount, a printed circuit board assembly, the printed circuit board assembly including a printed circuit board and an image sensor and a terminal mount mounted on the printed circuit board, the lens and the image sensor having been actively aligned to achieve a target imaging effect, the method including:
inserting a connector into the mounting hole on the rear cover for fixing;
inserting a portion of the printed circuit board assembly into the rear cover such that the terminal block is mated with the connector; and
and connecting the rear cover and the lens mount by using laser welding.
Optionally, the rear cover and the lens mount are made of metal.
Optionally, the connector is connected to a host, and the terminal block is electrically connected to the connector to transmit the image signal to the host for processing.
Optionally, inserting the connector into the mounting hole of the rear cover for fixing includes: the connector is fixed in a mounting hole on the rear cover by using a screw.
Optionally, the method further comprises: the camera front end assembly is generated by:
applying glue to the printed circuit board assembly;
fixing the lens on a carrying platform;
moving the position of the printed circuit board assembly so that the printed circuit board assembly is aligned with the lens to achieve a target imaging effect; and
curing the glue to bond the printed circuit board assembly and the lens to produce the camera head assembly.
Optionally, the printed circuit board assembly is not bonded to the lens mount.
The camera and the manufacturing method thereof have the following advantages:
under the condition that the front end assembly of the camera is not fixed with the rear cover, the terminal block and the connector are oppositely inserted, so that stress influencing the relative position of a lens and an image sensor in the front end assembly of the camera cannot be generated, and the imaging effect of the camera cannot be influenced.
And secondly, converting the position deviation accumulated by assembling the components into the position deviation between the front end assembly of the camera and the rear cover, wherein the position deviation does not influence the imaging effect of the camera. Furthermore, camera front end assembly spare and back lid are the metal material, and accessible laser welding melts the metal, thereby eliminates the positional deviation between the two.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 is an exploded view of a vehicle-mounted camera according to the present invention. Fig. 2 is a sectional view of an in-vehicle camera according to the present invention.
As shown in fig. 1, the in-vehicle camera may include a camera front end assembly 101, a rear cover 102, a connector 103, and a screw 104.
The camera head front end assembly 101 may include a lens 1011, a Holder 1012, and a PCBA 1013.
As shown in fig. 2, PCBA 1013 may include an image sensor 1014, a PCB (printed circuit board) 1015, and a terminal block 1016. The image sensor 1014 is mounted on the side of the PCB 1015 facing the lens, while the terminal block 1016 is mounted on the side of the PCB 1015 facing away from the lens.
The lens 1011 is composed of a lens and is capable of imaging an object to be photographed on the image sensor 1014, and the image sensor 1014 receives light passing through the lens and converts an optical signal into an electrical signal.
The lens 1011 and the image sensor 1014 in the camera head front end assembly 101 are aligned (active alignment) by the AA to achieve a target imaging effect (e.g., the imaged image achieves a target sharpness).
The side of the rear cover 102 facing away from the lens may be provided with mounting holes in advance for fixing the connector 103 using screws 104.
In the prior art, the front camera end assembly 101 and the rear cover 102 are fixed. For example, the camera head front end assembly 101 and the rear cover 102 may be fixed by means of gluing, screws, welding, or the like. The connector 103 is then inserted into a mounting hole in the back cover and the two are secured using screws 104.
The positions of the terminal block 1016 on the PCB 1015 and the positions of the mounting holes on the rear cover 102 are designed in advance so that the terminal block 1015 and the connector 103 can be aligned with each other, whereby the terminal block 1016 can be connected by mating with the connector 103 for subsequent transmission of image data signals. After the camera front end assembly 101 and the rear cover 102 are fixed, the relative position between the terminal block 1016 on the camera front end assembly 101 and the mounting hole of the rear cover 102 is determined, and thereby the relative position between the terminal block 1016 and the connector 103 is determined. However, some positional deviation occurs during the assembly of the camera front end assembly 101 (the assembly of the lens 1011, the lens holder 1012, and the PCBA 1013, as described below) and during the fixing of the camera front end assembly 101 to the rear cover 102, and thus the terminal holder 1016 and the connector 103 cannot be perfectly aligned (i.e., there is positional deviation). When the connector 103 is inserted into the mounting hole of the rear cover 102 and thus is inserted into the terminal block 1016, a large stress is generated by a positional deviation of the terminal block 1016 from the connector 103, and the stress acts on the camera head assembly 101 through the terminal block 1016 and affects the respective components thereof, for example, the stress may cause a displacement in the relative positions of the image sensor 1014 and the lens 1011. Although the shift is slight, the relative position between the image sensor 1014 and the lens 1011 is affected, thereby blurring the imaging.
In view of the above, the present invention provides an improved method of manufacturing an ADAS camera.
Specifically, the present invention first inserts the connector 103 into a mounting hole on the rear cover 102 and fixes it with the screw 104. A portion of the camera head front end assembly 101 is then inserted into the back cover 102 such that the terminal block 1016 mates with the connector 103. Finally laser welding is used to fix the camera front end assembly 101 and the back cover 102. Specifically, the lens holder 1012 and the rear cover 102 in the camera front end assembly 101 may be fixed using laser welding. The lens holder 1012 and the back cover 102 are made of metal.
In the scheme of the invention, the terminal base 1016 is inserted into the connector 103, and then the camera front end assembly 101 and the rear cover 102 are fixed, so that the stress generated by the insertion of the terminal base 1016 and the connector 103 in the prior art is avoided, the relative position where the image sensor 1014 and the lens 1011 are aligned to achieve the target imaging effect is not influenced, and the imaging effect of the camera is not influenced. The positional deviation generated during the process of mounting the components is finally converted into a positional deviation between the back cover 102 and the lens holder 1012, which does not affect the imaging effect of the camera.
Further, the lens holder 1012 and the back cover 102 of the present invention are made of metal, and during the laser welding process, the metal melts to eliminate the position offset between the back cover 102 and the lens holder 1012, i.e., the misalignment between the back cover 102 and the periphery of the lens holder 1012 is eliminated by the metal melting.
The assembly process of the camera head assembly 101 is described below.
As shown in fig. 1, camera head front end assembly 101 may include a lens 1011, a lens mount 1012, and a PCBA 1013.
As shown in FIG. 2, PCBA 1013 may include a PCB 1015, a lens-facing surface of PCB 1015 may have image sensor 1014 mounted thereon, and a lens-facing surface of PCB 1015 may have terminal block 1016 mounted thereon.
The lens 1011 and the lens holder 1012 may be connected by threads and glue to form a lens assembly (shown as 1011 and 1012 in fig. 2).
Specifically, the lens holder 1012 may cover an outer peripheral side of a part of the lens 1011. For example, the inside of the lens holder 1012 may have an internal thread, and a portion of the lens 1011 contacting the lens holder 1012 may have an external thread. The lens holder 1012 and the lens 1011 may be fixed by internal and external threads. Preferably, glue may be applied to the surfaces of the internal threads of the lens mount 1012 and the external threads of the lens 1011 to further fix the lens mount 1012 and the lens 1011 to form a lens assembly.
After the lens assembly is assembled, the bottom of the lens 1011 (the portion away from the object being photographed) can be bonded to the PCBA 1013 by glue (as shown in fig. 2). For example, a flange at the bottom of lens 1011 may be bonded to PCBA 1013 by glue.
In operation, the side of PCBA 1013 facing lens 1011 may be pre-coated with glue (e.g., AA glue) for connecting with lens 1011 (e.g., a flange at the bottom of lens 1011). Thus, PCBA 1013 may be bonded only to lens 1011 and not to lens mount 1012. Preferably, PCBA 1013 may not be in contact with lens mount 1012. Deformation of the lens mount 1012 due to temperature changes will thus not affect the relative position of the lens 1011 and the image sensor 1014 on the PCBA 1013, and thus the imaging quality.
Compared with the scheme that the PCBA and the lens are respectively bonded with the lens mount in the existing camera manufacturing technology, the invention ensures that the PCBA is only bonded with the lens and is not bonded with the lens mount. Therefore, when the temperature changes, the deformation of the lens mount will not affect the relative position of the PCBA and the lens, and therefore the relative position of the image sensor mounted on the PCBA and the lens is not affected, and further the imaging effect of the camera is not affected.
Further, the prior art fixes the PCBA such that the lens is aligned with the image sensor AA to achieve the target imaging effect. Since the structure of the lens becomes complex and heavier as the resolution of the camera increases, it is difficult to control the glue compensation amount in the AA alignment process of the lens and the image sensor, resulting in a decrease in the accuracy of the camera.
The invention can fix the lens on the carrying platform, clamp the PCBA by using the clamping jaw of the AA equipment, adjust the position of the PCBA until the image sensor and the lens on the PCBA achieve the target imaging effect, and then fix the relative position of the lens and the image sensor by curing glue by using UV illumination.
Fig. 3 is a flow chart of a method of manufacturing an ADAS camera according to the present invention.
The camera may include a camera front end assembly 101, a back cover 102, and a connector 103. The camera head front end assembly 101 may include a lens 1011, a lens holder 1012, and a printed circuit board assembly 1013. The printed circuit board assembly 1013 includes a printed circuit board 1015, and an image sensor 1014 and a terminal block 1016 mounted on the printed circuit board 1015, the image sensor 1014 being mounted on a lens-facing surface of the printed circuit board 1015, and the terminal block 1016 being mounted on a lens-facing surface of the printed circuit board 1015. The lens 1011 and image sensor 1014 have been actively aligned to achieve a target imaging effect.
At step 302, the connector 103 may be inserted into a mounting hole on the rear cover 102 for securing.
In one aspect, the connector 103 may be secured in a mounting hole on the back cover 102 using a screw 104.
At step 304, a portion of the printed circuit board assembly 1013 may be inserted into the back cover 102 such that the terminal blocks 1016 on the printed circuit board 1015 mate with the connectors 103.
At step 306, the back cover 102 may be coupled to the lens mount 1012 using laser welding.
In one aspect, the back cover 102 and the lens holder 1012 may be made of metal.
In one aspect, the connector 103 is connected to a host, and the terminal block 1016 makes electrical connection with the connector 103 to transmit image signals to the host for processing.
In one aspect, a camera head end assembly is generated by: applying glue to printed circuit board assembly 1013; fixing a lens 1011 on the stage; moving the position of the printed circuit board assembly 1013 such that the printed circuit board assembly 1013 is aligned with the lens 1011 to achieve a target imaging effect; and curing the glue to bond printed circuit board assembly 1013 with lens 1011 to produce a camera head assembly.
In one aspect, the printed circuit board assembly 1013 is not in contact with the lens holder 1012.
The camera and the manufacturing method thereof have the following advantages:
under the condition that the front end assembly of the camera is not fixed with the rear cover, the terminal base and the connector are oppositely inserted, so that stress influencing the relative position of a lens and an image sensor in the front end assembly of the camera cannot be generated, and the imaging effect of the camera cannot be influenced.
And secondly, converting the position deviation accumulated by assembling the components into the position deviation between the front end assembly of the camera and the rear cover, wherein the position deviation does not influence the imaging effect of the camera.
And thirdly, the camera front end assembly and the rear cover are both made of metal materials, and metal can be melted through laser welding, so that the position deviation between the camera front end assembly and the rear cover is eliminated.
The description herein is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not intended to be limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
