Description

Multi-view camera assembling equipment

Technical Field

Background

With the development of the automobile electronic industry, the automatic driving and artificial intelligence of automobiles come, and the application and the requirement on the vehicle-mounted camera are higher and higher. Under this condition, the monocular camera has irreconcilable defect in the aspect of measuring range and distance, and the visual angle is wider, and the accurate distance that can detect is shorter, and the visual angle is narrower, and the accurate distance that detects is longer, can't satisfy simultaneously that the high accuracy vision of multidimension is formed images and is surveyed in the space. The problem of inaccurate unclear distance of different distance formation of image can be solved to binocular camera or the camera more than binocular. The binocular camera calculates the distance from the two lenses to the imaging object in a similar triangular mode through the parallax of the imaging pictures of the two cameras, and then calculates the actual distance of the imaging object through the parallax of the two cameras, so that a monocular camera is not needed, and a large amount of databases need to be maintained at the early stage to match the actual imaging object. Therefore, a binocular camera or a camera with more than two eyes (hereinafter, collectively referred to as a multi-view camera) is a mainstream configuration of the smart car.

The camera generally includes an imaging chip, a lens and a lens or an imaging chip driving device, wherein the lens and the image sensor should be located on an optical axis of the lens, and the image sensor is perpendicular to the optical axis. Therefore, in the process of assembling the camera, the assembly tolerance of all the components is required to be within a reasonable range, and the requirement is difficult to achieve through manual assembly. Therefore, manufacturers generally adopt Active Alignment (AA) equipment to complete automatic Alignment and solidification of a lens (possibly including a lens driving device) and a lens holder (generally including an image sensor), so as to ensure that the center of a photographed image is clearest, four corners of the image have uniform definition, and the consistency of the camera module is improved.

The lens mount of the multi-view camera is generally integrally formed or fixedly connected together, and a plurality of lenses need to be assembled at different positions of the lens mount respectively during assembly. The existing assembling equipment applied to the monocular camera is not suitable for the monocular camera.

The height and spacing of the fixed lamps 17 required for curing cameras of different sizes can be determined by programming a control program, and full-automatic control can be realized. The lens module can adapt to different lens modules and different alignment devices, and has wide application range. Can be matched with other modules of the first aligning device 100 in position, reduces the occupied area of the aligning station and miniaturizes the manufacturing device.

In this embodiment, the bracket 11 has two fixing arms 111 extending vertically upward. The slide rail 12 is an elongated rail fixed to the fixing arm 111. The fixing portion 13 has a sliding slot formed on a surface facing the sliding rail 12, the sliding slot being engaged with the sliding rail 12, and a supporting platform 131 is provided on the top.

The first driving assembly 14 mainly includes a servo motor 141 disposed at one side of the bracket 11, a screw rod 142 movably connected to the bracket 11, a timing belt 143 connecting an output shaft of the servo motor 141 and a lower end of the screw rod 142, and a cross bar 145 fixedly connected to a bearing block 144 of the screw rod 142. Wherein, the screw rod 142 is vertically arranged, and holes 112, 113 for inserting the screw rod 142 and allowing it to rotate are formed on the bracket 11. The cross bar 145 is horizontally disposed, and both ends thereof are connected to the two fixing portions 13, respectively. The servo motor 141 is connected to the screw rod 142 through a flexible timing belt 143, and the vibration of the servo motor 141 is not easily transmitted to the arm 16 through the timing belt 143, thereby ensuring the stability of the fixed lamp 17. The fixing portions 13 are fixedly connected by a rigid cross bar 145, so that stable synchronous movement can be realized, and the curing lamps 17 are always positioned on the same horizontal plane.

Two sets of photoelectric switches 18 are fixed to the holder 11. Two sets of photoelectric switches 18 are arranged one above the other next to the sliding rail 12. In order to adjust the position of the photoelectric switch 18, in the present embodiment, the photoelectric switch 18 is slidably connected to a slide rail 182 through a slider 181, and the slide rail 182 is fixed on a side wall of one of the fixing arms 111. Thus, the position of the photoelectric switch 18 in the Z-axis direction can also be adjusted. An L-shaped shielding piece 132 is further fixed on the surface of the fixing portion 13 facing away from the slide rail 12, and the shielding piece 132 is bent from the surface of the fixing portion 13 facing away from the slide rail 12 to the front of the side arm of the fixing arm 111. When the fixing portion 13 moves up and down, the shielding piece 132 can be inserted into the photoelectric switch 18 to shield the photoelectric switch from receiving signals, so that whether the fixing portion 13 reaches a predetermined position can be determined.

The second driving assembly 15 mainly includes an electric cylinder 151 fixed to the supporting platform 131 of the fixing portion 13, a rib 152 fixed to a casing of the electric cylinder, a slide plate 153, and a top plate 154 extending substantially perpendicularly from an end of the slide plate. Among them, the electric cylinder 151 is preferably a servo-type electric cylinder, and the movement control is more accurate. The output shaft 1511 of the electric cylinder 151 extends in the X-axis direction. The rib 152 serves as a slide rail and also extends in the X-axis direction. The slide plate 153 is formed with a groove adapted to the protrusion 152, and the protrusion 152 is inserted into the groove to slidably connect the slide plate 153 and the protrusion 152. The top plate 154 is connected to an output shaft 1511 of the electric cylinder 151, and specifically, the center of the top plate 154 abuts against and is fixedly connected to the end of the output shaft 1511. Thus, when the electric cylinder 151 is operated, the output shaft 1511 drives the top plate 154 and the sliding plate 153 to move, and further drives the arm 16 connected to the sliding plate 153 to move along the X-axis direction.

The arm 16 is used to hold a curing light 17. The support arm 16 mainly includes an arc-shaped or V-shaped connecting portion 161 (arc-shaped in this embodiment), and the curing lamps 17 are fixed at two ends of the connecting portion 161, so that the curing lamps 17 fixed by the two oppositely-arranged support arms 16 can be annular, and surround the camera to be cured around the center, thereby ensuring uniform curing temperature, enabling the glue between the lens and the lens holder to be synchronously cured, and achieving good curing effect.

In order to fix the curing lamp 17 conveniently, the two ends of the connecting portion 161 further form a fixing portion 1611 extending towards the center of the arc structure or a position close to the center of the arc structure, and an arc through groove is formed on the fixing portion 1611. A square pyramid 1612 is fixed to the lower end surface of the fixing portion 1611. The upper end surface of the cone 1612 may be formed with a groove or a cylinder inserted into the arc-shaped through groove, thereby facilitating the connection of the fixing portion 1611 and the cone 1612 by means of gluing. The curing light 17 is fixed on the lower end surface of the square cone 1612 or embedded in the square cone. The cone 1612 is for directing the light emitting direction of the curing light 17 to the obliquely lower side of the fixing unit 1611, so as to prevent the arm 16 from contacting the lens of the camera.

In addition, in order to center the curing light 17 away from the bracket 11 so that the curing mechanism 10 can better mate with the first aligner 100, the arm 16 further includes a second connecting portion 162 that is substantially L-shaped. One end of the second connecting portion 162 is fixedly connected to the sliding plate 153, and the other end is fixedly connected to the middle portion or a portion near the middle portion of the connecting portion 161 having an arc shape or a V shape. The second connecting portion 162 may also be fixed on the upper surface of the sliding plate 153 by a plate-shaped third connecting portion 163, so that the connection is more stable. It will be appreciated that the second connecting portion may also be substantially zigzag-shaped, so that the third connecting portion may be omitted.

The curing mechanism 10 is disposed between the robot 61 and the first transfer device 31. When the robot 61 grips the lens for alignment operation, the second driving assembly 15 of the curing mechanism 10 drives the two arms 16 apart to allow the robot 61 to pass through the gap between the arms 16 for alignment operation. When the robot 61 finishes the alignment operation, the second driving assembly 15 of the curing mechanism 10 drives the two support arms 16 to approach each other, so that the curing lamp 17 is aligned with the gap between the lens and the lens holder for uniform curing. After curing is completed, the second drive assembly 15 of the curing mechanism 10 again drives the two arms 16 apart, allowing the robotic arm 61 to return the aligned and cured camera to the fixture 903. Thereafter, the robot 61 retracts, and the next jig 903 is conveyed to the alignment station and is jacked up to continue the alignment operation. Therefore, the invention skillfully combines the curing mechanism 10 and the manipulator 61, so that the curing mechanism and the manipulator cooperate to work, thereby optimizing the working process and improving the curing quality of the product. Meanwhile, the floor area of the alignment equipment is reduced, and the manufacturing equipment is miniaturized.

In this embodiment, the first aligning apparatus 100 further includes a robot arm, not shown, for taking the lens and the lens mount away from the jig for performing alignment, and a transfer unit for transferring the jig 903 from the first transfer device 31 to the second transfer device 32, so that the automation rate is improved, and the labor cost is saved.

The first movable base 92 can move along the X-axis direction relative to the fixed base 91 by means of a slide rail and a slider engaged with each other. The second movable base 93 is movable in the Y-axis direction with respect to the first movable base 92 by means of slide rails and sliders engaged with each other. The single-shaft module 95 may include a lead screw therein, the lead screw may be connected to an output shaft of the servo motor 94 through a synchronous belt, and may rotate synchronously with the output shaft of the servo motor 94, and a bearing seat of the lead screw may be connected to the distance-increasing mirror 96, so as to drive the distance-increasing mirror 96 to move in the Z-axis direction. In this manner, movement of the range mirror 96 in the horizontal direction may be manually adjusted, while movement in the vertical direction may be automatically accomplished. The distance-increasing mirror module 90 is fixed between the first conveying device 31 and the second conveying device 32, and the distance-increasing mirror 96 extends towards the track 311 direction of the first conveying device 31 and is located above the alignment station, specifically below the light outlet of the first light pipe.

Referring to fig. 6, 7 and 12, the second light source 83 is a parallel light source, and specifically includes a first light pipe 831 and a plurality of second light pipes 832. The first light pipe 831 is vertically fixed, and the light emitting direction thereof is perpendicular to the surface of the base 20 and faces the alignment station and the optical center of the range finder 96. The plurality of second light pipes 832 are uniformly circumferentially disposed under the first light pipe 831. If a sphere is defined, the optical axes of the first light pipe 831 and the plurality of second light pipes 832 should be located in the diameter direction of the sphere, and the light outlets of the first light pipe 831 and the plurality of second light pipes 832 are located on the sphere. When the alignment is performed, the lens and the lens seat are positioned at the center of the sphere.

In this embodiment, the plurality of second light pipes 832 are fixed to the first layer plate 71 of the fixing frame 70 by fixing members 833.

The micro motion platform 8334 is slidably coupled to the rail 8333 via a slider. The micro-motion platform 8334 is a structure capable of manually adjusting the angle, and specifically can be finely adjusted along two curved surfaces, so as to ensure the light-emitting direction of the second light pipe 832. In this embodiment, two second light pipes 832 are fixed on each rail 8332, so that the light intensity of the second light source 83 is more uniform.

The first light source 81 and the Chart image fixing part 82 are fixed on the second layer plate 72 of the fixing frame 70. The first light source 81 is a surface light source for illuminating the Chart fixed to the Chart fixing section 82.

In operation, the jig 903 carrying the lens and lens mount to be aligned and cured (having completed the cleaning and dispensing operations) is transferred to the alignment station by the first transfer device 31, and the lift-up mechanism 50 located below the alignment station lifts up the jig 903 so that the jig 903 is suspended above the first transfer device 31. The third driving assembly 60 drives the manipulator 61 to move from a position far away from the first conveying device 31 to a position above the clamp 903, to clamp the lens, and move to a position above the corresponding lens mount to start aligning, after the aligning is completed, the manipulator 61 remains still, and the second driving assembly 15 of the curing mechanism 10 drives the two support arms 16 to approach, so that the curing lamp 17 aligns with the glue between the lens and the lens mount, and uniform curing is performed. After the curing is completed, the second driving assembly 15 of the curing mechanism 10 drives the two arms 16 to separate again, and the robot 61 returns the aligned and cured camera to the jig 903. Then, the third driving assembly 60 drives the mechanical arm 61 to retract, and the next fixture 903 is conveyed to the alignment station and is jacked up to continue the alignment operation. The lens holder having completed the aligning and curing work is picked up, and the empty carrier is transferred to the second transfer device 32 and then carried to a predetermined position by the second transfer device 32.
