Description
Technical Field
The present disclosure relates to the field of optical lenses, and more particularly, to a camera shooting and assembling apparatus and an assembling method thereof.
Background
In recent years, with the popularization and development of intelligent devices, especially the rapid development of the mobile phone industry, the demand of the market for cameras is increasing. The intelligent equipment such as cell-phone is constantly iterated and is updated, and its use is more convenient, and the performance constantly promotes, and then requires cell-phone camera module manufacturer to constantly upgrade the optimization to cell-phone camera module. On one hand, the market expects the camera product to have higher imaging quality, and on the other hand, the camera product is expected to be more matched with the structural design, the shape design and the like of the mobile phone.
Because the lens cone surface of camera module probably produces reflected light etc. can cause the interference to the formation of image light in the light path, and then causes the image quality of camera module poor easily. In order to solve the problem of light reflection of the lens barrel and increase the visual uniformity of the panel, a coating is usually disposed on the surface of the lens barrel, and the surface of the coating usually includes a super black matte coating. The surface of the coating film is usually frosted, so that light on the surface of the lens barrel can be in a diffuse reflection state, the problem of over brightness caused by concentrated reflection is solved, and the influence of stray light on the imaging quality of a lens group in the lens barrel is further reduced. The product yield of the camera module can be improved.
However, when the camera module is assembled with other components, the camera shooting device is usually used to directly contact the film coating of the lens barrel, and when the camera shooting device drives the camera module to move, for example, when the camera shooting device rotates along the optical axis, force is applied to the film coating of the lens barrel, and the film coating can cause scratches, scratches and other problems. The coating is easily scratched, scratched or contaminated, and the coating is difficult to repair, thereby affecting the imaging quality.
The light absorption layers made of other materials, such as carbon layers containing wax materials, can be replaced by extinction materials, although stray light can be weakened and the light absorption layers have certain strength, the extinction performance of the light absorption layers is not as strong as that of a super black extinction coating, and the problem of coating scratch caused by rotation of a camera shooting device cannot be avoided.
Usually, an antireflection film may be plated on the surface of the lens barrel, and a waterproof film layer may be plated on the outer side of the antireflection film. The low refractive index material layer and the high refractive index material layer in the antireflection film layer are alternately arranged for multiple times, for example, the materials are respectively chromium oxide and silicon dioxide, and the corresponding thicknesses are 30 nm-500 nm and 10 nm-20 nm. The waterproof film layer can be made of fluoride, the contact angle is larger than 110 degrees, and the thickness is 4 nm-20 nm. The waterproof film layer has higher hardness and good waterproofness, can protect the antireflection film and can reduce scratches and pollution of the film layer. But when setting up multilayer coating, the technology of membrane preparation is numerous complicated, and is consuming time longer, and has promoted the cost of manufacture of camera module.
In order to protect the coating of the lens barrel, some protective measures for the coating are taken, such as: the front end of the camera lens module is additionally provided with the transparent plastic protective cover, but the method increases the process and the process cost, and the transparent plastic protective cover can refract light rays, thereby influencing the imaging quality of the lens group in the lens cone. This protection counteracts the effect of the super black matte coating and is contrary to the purpose for which the super black matte coating is provided.

The application provides a camera shooting device includes according to the preface along the direction of predetermineeing the axis by first side orientation second side: an air guide pipe section, an avoiding pipe section and a tooth-shaped supporting pipe section. The air guide pipe section, the avoiding pipe section and the tooth-shaped supporting pipe section are hermetically connected, the air guide pipe section is located at a first end, facing a first side, of the avoiding pipe section, the tooth-shaped supporting pipe section is located at a second end, facing a second side, of the avoiding pipe section, and inner holes of the air guide pipe section, the avoiding pipe section and the tooth-shaped supporting pipe section are sequentially communicated.
The air guide pipe section is connected to the first end, facing the first side, of the avoidance pipe section in a sealing mode, and the inner diameter of the air guide pipe section is smaller than that of the avoidance pipe section. The difference between the inner bore of the air duct section and the inner bore of the escape duct section results in a connecting surface between the two inner bores, which is generally considered to be the end surface of the air duct section facing the second side. The inner hole of the air guide pipe section can be used for air suction or air inflation.
The inner hole of the avoiding pipe section is used for accommodating the part to be shot of the camera to be shot. When the camera shooting device sucks the camera, one part of the camera can enter the inner hole of the avoiding pipe section. At the moment, approximately sealed spaces are formed among the camera, the tooth-shaped supporting pipe section, the avoiding pipe section and the air guide pipe section, and when the vacuum air pumping device is used for pumping air in the inner hole of the air guide pipe section, negative pressure relative to the external space is formed in the sealed space, so that the camera is sucked by the camera shooting device.
The tooth-shaped supporting pipe section is matched with a lens cone of the camera to be sucked. Specifically, the tooth-shaped supporting pipe section is embedded with a middle boss of a lens barrel of the camera in the circumferential direction, and the tooth-shaped supporting pipe section abuts against the lens barrel in the direction parallel to the preset axis, so that the object-side end surface of the camera is spaced from the connection surface of the air guide pipe section and the avoiding pipe section, or the object-side end surface of the camera is in contact with the connection surface of the points of the air guide pipe section and the avoiding pipe section without extrusion. The part of the camera higher than the upper end of the middle boss penetrates through an inner hole of the tooth-shaped support pipe section and is positioned in the avoiding pipe section; the part of the camera corresponding to the middle pipe section is positioned in an inner hole of the tooth-shaped supporting pipe section; the middle boss is embedded with the tooth-shaped supporting pipe section and is higher than the lower end of the tooth-shaped supporting pipe section when being sucked. In the camera, the part from the bottom end of the middle boss to the top end of the camera is regarded as a shot part. Specifically, one end of the tooth-shaped supporting pipe section facing the second side abuts against the lens barrel. The profile of tooth supports the pipeline section and waits that the camera that absorbs coincide, and on using the camera that the camera shooting device absorb to install other parts, for example take the screwed camera need twist soon into optical anti-shake motor time, and the profile of tooth supports the pipeline section and can follow the circumference of predetermineeing the axis and drive the camera rotation.
Illustratively, the material of the camera shooting device can be wear-resistant and high-hardness material, such as stainless steel. The hardness of material is higher and wear-resisting, can make the camera shoot device system formula structure as an organic whole, and the camera of integral type structure shoots the device and is more suitable for by the operation. The tooth-shaped supporting pipe section can be well embedded with a middle boss of a lens barrel of the camera in the circumferential direction, and the tooth-shaped supporting pipe section can well drive the camera to rotate. And the surface finish of the avoiding pipe section and the tooth-shaped supporting pipe section in the camera shooting device can be better. Better surface finish can also reduce the probability of accidental scratching. And can prolong the life of camera shooting device, effectively practice thrift manufacturing cost, can also reduce the cleanness to camera shooting device.
The application provides a camera shooting device is used for when shooting the camera, and the extinction coating of coating can not contact the object on the lens cone of camera, has avoided fish tail, scotch etc. that probably produce when assembling camera and other spare parts. The application provides a camera shooting device can be convenient shoot, control and place the camera, and the shooting camera that can be more stable.
Referring to fig. 1, the camera head 300 may include a middle flange 311 and a middle boss 313 disposed on an upper side of the middle flange 311. The lower portion of camera head 300 may include a connection, such as a screw thread.
The camera shooting device 100 may include an air guide tube segment 110, an avoidance tube segment 120, and a tooth-shaped support tube segment 200, which are integrally formed, and inner bores of the air guide tube segment 110, the avoidance tube segment 120, and the tooth-shaped support tube segment 200 are communicated. The vertical direction is taken as the direction of the preset axis, the upper end of the avoiding pipe section 120 is the first end, and the lower end of the avoiding pipe section 120 is the second end. The lower end of the air guide duct section 110 is connected to the first end of the avoidance duct section 120, and the diameter of the inner hole 111 of the air guide duct section 110 is smaller than the inner diameter of the avoidance duct section 120. The toothed support tube segment 200 is fixedly connected to the second end of the bypass tube segment 120.
When the camera 300 is shot, the tooth-shaped supporting pipe section 200 is embedded with the middle boss 313 of the camera 300 in the circumferential direction, and the lower end 201 of the tooth-shaped supporting pipe section 200 is abutted against the lens barrel of the camera 300 in the axial direction. The inner bore of the escape tube section 120 and the inner bore of the toothed support tube section 200 are used to accommodate the ingested part of the camera head 300. The distance from the first end of the avoidance tube segment 120 to the lower end 201 of the toothed support tube segment 200 along the preset axis is greater than the height of the portion of the camera head 300 that is captured (the length along the preset axis). When the camera 300 is photographed, the object side end thereof may have a gap with the lower end of the air duct section 110, and the thickness of the gap may be 0.2 mm.
When air is drawn from the inner hole 111 of the air guide duct section 110, air in the inner hole of the escape duct section 120 communicating with the inner hole 111 of the air guide duct section 110 is also drawn out, and the gap between the object side end of the camera head 300 and the lower end of the air guide duct section 110 is small, so that the suction force of the camera head shooting device 100 to the camera head 300 can be improved.
Conceivably, in the camera shooting device 100, the sizes of the avoidance pipe section 120, the tooth-shaped support pipe section 200 and the air guide pipe section 110 can be adjusted according to the specific size of the camera 300 to be shot, so that the camera shooting device can be applied to different types of cameras 300, and the application range of the camera shooting device 110 is wider. For example, the lens closest to the object side of the wide-angle camera may have a protruding convex surface, and the distance from the lower end of the air guide duct section 110 to the object side end of the wide-angle camera may be set to be longer, so as to avoid the influence of the convex surface of the lens on the shooting stability, ensure that the shot camera 300 does not deviate from the position of the camera shooting device 100, and further ensure the matching precision when the camera 300 is installed on other parts. For example, the control accuracy of the center alignment of the optical anti-shake motor when mounted thereto is improved. Thereby promote the yield of the module of making a video recording, promote the efficiency of making the module of making a video recording and reduction in production cost.
In an exemplary embodiment, the bypass tube section 120 includes a radially inwardly protruding stop flange 130 near the second end, a constriction 131 is formed in the inner bore of the bypass tube section 120 corresponding to the stop flange 130, and an annular groove 121 is formed in the bypass tube section 120 near the first end. It can be seen that the diameter of the constriction 131 is smaller than the diameter of the ring groove 121.
Illustratively, the camera head 300 includes a radially extending upper flange 312, the upper flange 312 proximate an object-side end of the camera head 300. The inner diameter of the throat 131 of the camera shooting device 100 of the present application is not smaller than the outer diameter of the upper flange 312, so as to ensure that the shot part of the camera 300 can enter the avoidance pipe section 120. In addition, at each position in the circumferential direction, the difference between the diameter of the annular groove 121 of the avoidance pipe section 120 and the diameter of the necking 121, that is, the radial distance between the groove bottom of the annular groove 121 of the avoidance pipe section 120 and the inner wall surface of the limit flange 130 is greater than the radial protrusion distance of the upper flange 312 of the camera 300.
After the upper flange 312 of the camera 300 axially passes through the throat 131, the diameter of the part of the lens barrel of the camera 300 corresponding to the position of the throat 131 is smaller, and a larger gap is formed between the lens barrel and the throat 131, so that the camera 300 can radially move in the camera shooting device 100. Because the limiting flange 130 can radially abut against the outer side wall of the lens barrel of the camera 300, so as to limit the radial movement of the camera 300, when the outer side wall of the lens barrel of the camera 300 is fitted with the limiting flange 130, the camera 300 radially moves to a radial limit position, but the groove bottom at any position of the ring groove 121 is always kept spaced from the upper flange 312 of the camera 300. Moreover, since the overall height of the avoidance tube segment 120 and the support tube segment 200 in the vertical direction is greater than the height from the top end of the middle flange 311 of the camera head 300 (which is located on the same plane as the bottom end of the middle boss 313) to the top end of the lens barrel, any position of the top end of the lens barrel always keeps a gap from the lower end of the air guide tube segment 110 (which is located on the same plane as the upper end of the avoidance tube segment 120). The sucked camera 300 is freely abutted against the camera shooting device 100, and the upper flange 312 is overhead in the inner hole of the avoidance pipe section 120, so that the upper flange 312 of the lens 300 can be protected in all directions.
The end face and the periphery of the object side end of the camera 300 can be guaranteed to be complete by arranging the necking 131 and the groove 121 formed by the limiting flange 130, and scratching is avoided. Moreover, it is avoided that the camera shooting device 100 squeezes the object side of the camera 300 when operating the camera 300, and thus Modulation Transfer Function (MTF) failure caused by the force applied to the object side of the camera 300 is avoided.
In an exemplary embodiment, the diameter of the ring groove 121 is at least 0.55mm greater than the diameter of the throat 131.
In the exemplary embodiment, annular groove 121 is coaxial with throat 131. The coaxial arrangement of the annular groove 121 and the necking 131 can enable the depth of the annular groove 121 to be close to each other, and the upper flange 312 can be better avoided.
In the exemplary embodiment, the axial width of ring groove 121 is greater than the axial width of throat 131. The wider circumferential groove 121 may better prevent the upper flange 312 of the camera head 300 from being compressed during ingestion or discharge. Illustratively, the width of the ring groove 121 in the preset axial direction is 0.2mm more than the thickness of the upper flange 312 of the camera head 300 in the preset axial direction. The axial width of the ring groove 121 and thus the axial width of the throat 131 is controlled. On one hand, the processing of the bypass pipe section 120 is facilitated, and on the other hand, the necking 131, namely the limiting flange 130, has a proper axial width. Which facilitates better abutment of the position-defining flange 130 against the captured camera head 300. The limiting flange 130 is matched with the tooth-shaped supporting pipe section 200, so that the camera 300 is supported three-dimensionally, the camera 300 is prevented from rotating in a plane parallel to a preset axis, and the object side end of the camera 300 is further prevented from colliding and scratching with the air guide pipe section 110 or the avoiding pipe section 120.
The arrangement of the tooth-shaped supporting pipe section 200 and the ring groove 121 constructs a wider closed area for the periphery of the end face of the camera 300, changes the stress point and the contact surface of the camera 300 and the camera shooting device 100 to the middle of the camera 300, avoids the extinction coating 320 from being directly or indirectly contacted with the outside, and avoids the extinction coating 320 from being subjected to pressure and friction force in the process of manufacturing. And compare the stress point that the camera shot in current device at the terminal surface of lens cone, when the camera shooting device 100 of this application shot camera 300, the object side end of lens group 330 was kept away from to the stress point and the contact surface of camera 300, avoided being located the condition of the slight perk of lens that the not co-altitude produced at camera 300 both ends in the adsorption process, guaranteed the stability and the cooperation precision of lens in the lens group 300.
In an exemplary embodiment, the upper end of the position-defining flange 130 is beveled such that the inner bore of the bypass tube section 120 further includes a first tapered opening disposed between the annular groove 121 and the constriction 131. The first taper is provided to facilitate removal of the camera 300 from the camera shooting device 100.
In the exemplary embodiment, the groove bottom of the ring groove 121 is a tapered surface having a smaller diameter toward one end of the throat 131.
In an exemplary embodiment, the lower end of the retention flange 130 is beveled such that the inner bore of the bypass tube section 120 further includes a second taper disposed on the side of the throat 131 facing the second end. Providing the second taper facilitates the camera shooting apparatus 100 shooting the camera 300.
In the exemplary embodiment, toothed support tube segment 200 includes four lobes that are evenly spaced in the circumferential direction. Referring to fig. 3, when four middle bosses 313 are uniformly distributed on the camera 300, the camera 300 has four spaces between the middle bosses 313. The teeth of the toothed support tube segment 200 are adapted to fit into the corresponding spaces. The lower ends of the teeth may pass through the spaces between the intermediate bosses 313 and abut against the upper end of the intermediate flange 311, i.e., the lower ends of the teeth are flush with the lower ends of the intermediate bosses 313. Both sides of the convex teeth in the circumferential direction of the preset axis are respectively matched with the middle boss 313 on the corresponding side. The four teeth of the camera shooting device 100 can provide a stable and balanced supporting surface for the shot camera 300. And when twisting camera 300, the dogtooth of equipartition can be more symmetrical provides the moment of torsion, helps better twisting camera 300.
Referring to fig. 2 and 3, the present application provides a camera shooting device 100, which includes an air duct section 110, and further includes a rubber ring 600.
