Description

Technical Field

[0001] The present invention relates to the technical field of camera assembly, and in particular to a full-automatic dual-station multi-group AA device for cameras. Background Art

[0002] The past decade has been the golden era of the development of smart phones, and the mobile phone camera market has grown rapidly along with the growth of the terminal. Cameras have evolved from improving pixel quality to upgrading functions later; from single cameras to multi-cameras, with the continuous emergence of ultra-wide-angle and large-aperture cameras; these improvements have brought different high-quality experiences to a large number of mobile phone users and increased more choices. Even so, it still cannot stop the continuous pursuit of camera functions by the majority of users.

[0003] In this environment of market demands, "digital zoom" and "optical zoom" have quietly appeared at the press conferences of many smart phone brands, attracting the favor of a large number of users. The biggest change is to achieve digital or optical zoom through certain technical means, enabling the camera to achieve the function of "taking distant views", that is, a telephoto camera; however, with the continuous update of telephoto lenses, many terminal mobile phones can achieve 2X, 3X, 5X, or even 10X zoom, and then the "periscope camera" emerged. These are all continuous upgrades and transformations of the camera structure, and higher requirements are imposed on the related camera packaging processes.

[0004] During the camera assembly process, multiple assemblies of components such as image sensors (Sensors) and lenses (Lenses) are involved. Traditional assembly devices such as CSP and COB are all for the mobile assembly of components according to the parameters adjusted by the device (Passive Alignment, passive alignment technology). Therefore, the stacking tolerance of components is getting larger and larger, and the final effect on the camera is that the clearest position of the photographed image may deviate from the center of the image, and the clarity of the four corners is uneven.

[0005] The so-called AA process, that is, Active Alignment, which is interpreted in Chinese as active alignment, is a technology for determining the relative positions during the assembly of components. When the device of the AA process assembles each component, the device will detect the semi-finished product to be assembled and actively align according to the actual situation of the semi-finished product to be assembled, and then assemble the next component in place. This active alignment technology can adjust the lens alignment to 6 degrees of freedom (X, Y, Z, Tx, Ty, Tz), effectively reducing the assembly tolerance of the entire module, effectively improving the consistency of camera products, and also creating possibilities for the packaging of higher-order camera products. When assembling the Sensor and the Lens, it is necessary to ensure that the relative X-axis, Y-axis, Z-axis, Tx-axis, Ty-axis, and Tz-axis of the Sensor and the Lens are in the best position to ensure the coaxiality of their optical axes.

[0006] In the current AA process of cameras, precise focusing is achieved by aligning a lens component and a Sensor component. However, due to the complex optical path of periscope cameras, the tight structural design places further requirements on their AA process. Compared with conventional cameras, multiple AA processes are required to complete the assembly process of the entire camera. During multiple AA processes, due to excessive turnover and process conversion, the finished cameras cannot meet the expected design requirements. Summary of the Invention

[0077] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] Refer to Figures 1 to 2As shown in the figure, the present invention provides a fully automatic double-station multi-group AA device for a camera, which includes two AA devices 1 arranged side by side, a first feeding device 2 for feeding the first material to the AA device 1, a second feeding device 3 for feeding the second material to the AA device 1, and a third feeding device 4 for feeding the third material to the AA device 1. The first feeding device 2 and the second feeding device 3 are arranged on the same side of the two AA devices 1, and the third feeding device 4 is arranged on the other side of the two AA devices 1. Each AA device 1 includes a first positioning and clamping mechanism 11 and a second positioning and clamping mechanism 12 arranged opposite to each other, and a fixture platform mechanism 13 arranged below between the first positioning and clamping mechanism 11 and the second positioning and clamping mechanism 12. The fixture platform mechanism 13 is used to fix the first material, the first positioning and clamping mechanism 11 is used to clamp and fix the second material, and the second positioning and clamping mechanism 12 is used to clamp and fix the third material. The fixture platform mechanism 13, the first positioning and clamping mechanism 11, and the second positioning and clamping mechanism 12 cooperate with each other to realize the AA operation of the first material, the second material, and the third material.

[0079] In a specific embodiment, as Figure 20 shown, the first material is a Sensor component 7 (the Sensor component 7 is welded on a PCB board), the second material is an AF lens 8, the third material is an FF lens 9, and the glue is a double-layer glue 10. The Sensor component 7 is fixed on the first platform 131 of the fixture platform mechanism 13, and the fixture platform mechanism 13 is a three-axis precision motion platform. The AF lens 8 is clamped and fixed by the first positioning and clamping mechanism 11, and the FF lens 9 is clamped and fixed by the second positioning and clamping mechanism 12. Both the first positioning and clamping mechanism 11 and the second positioning and clamping mechanism 12 are 6-axis positioning and clamping mechanisms.

[0080] Referring to Figures 4 to 8 shown, the glue application mechanism:

[0081] Each AA device 1 further includes a glue application mechanism 14. Each glue application mechanism 14 includes two dispensing modules 141, two glue breaking detection modules 142, a UV curing irradiator 143, and two glue cleaning modules 144. The two dispensing modules 141 are arranged on one side of the second positioning and clamping mechanism 12 and are respectively used to apply glue to the first material and the second material. Each glue breaking detection module 142 is arranged on one side of a dispensing module 141 and is used to detect the glue application condition of the first material or the second material. The UV curing irradiator 143 is arranged above the first positioning and clamping mechanism 11 and the second positioning and clamping mechanism 12 and is used to irradiate and cure the assembled first material, second material, and third material. Each glue cleaning module 144 is arranged below a dispensing module 141 and is used to clean the residual glue of the dispensing module 141.

[0082] The dispensing module 141 includes a dispensing syringe and a Z-axis drive module for driving the lifting of the dispensing syringe. At the same time, since the first positioning and clamping mechanism 11 needs to clamp the AF lens 8 from the second platform 132, in order to prevent the error of each clamping from affecting the accuracy of the AA operation, a laser altimeter is also provided on one side of the dispensing syringe for applying glue to the AF lens 8, which is used to measure the height of each AF lens 8 grasped by the first positioning and clamping mechanism 11 and feedback the measurement result to the background, so that the first positioning and clamping mechanism 11 can make corresponding adjustments in time. The glue-breaking detection module 142 includes a detection camera for detecting the glue application condition after the dispensing module 141 applies glue to the Sensor component 7 or the AF lens 8.

[0083] The glue cleaning module 144 includes a glue cleaning gripper, a gripper opening and closing cylinder for driving the opening and closing of the glue cleaning gripper, a lifting drive cylinder for driving the lifting of the glue cleaning gripper, and a telescopic drive cylinder for driving the extension or retraction of the glue cleaning gripper. When it is necessary to clean the needle tip of the dispensing syringe, the steps are as follows: the lifting drive cylinder drives the glue cleaning gripper to rise - the gripper opening and closing cylinder drives the glue cleaning gripper to open - the telescopic drive cylinder drives the glue cleaning gripper to extend - the gripper opening and closing cylinder drives the glue cleaning gripper to close to clamp the needle tip - the lifting drive cylinder drives the glue cleaning gripper to descend, completing one glue cleaning action.

[0084] The UV curing irradiator 143 includes an irradiator mounting plate 1431, two arc-shaped guide rails 1432 oppositely arranged at the bottom of the irradiator mounting plate 1431, and two UV lamp assemblies 1433 slidably arranged on each arc-shaped guide rail 1432; each UV lamp assembly 1433 moves through the arc-shaped guide rail 1432 to adjust its position on the irradiator mounting plate 1431; each UV lamp assembly 1433 includes two UV lamps arranged up and down and two UV lamp adjusting frames; each UV lamp is installed on the arc-shaped guide rail 1432 through a UV lamp adjusting frame; the UV lamp adjusting frame includes an irradiation height adjusting module, an irradiation surface angle adjusting module, an irradiation pitch angle adjusting module, and an irradiation horizontal distance adjusting module arranged on one side of the irradiation pitch angle adjusting module in sequence from top to bottom.

[0085] In the UV curing irradiator 143, the radian of each arc-shaped guide rail 1432 is 130°, the moving range of each UV lamp assembly 1433 on the arc-shaped guide rail 1432 is ±65°, an arc-shaped slot is opened along the arc direction on the arc-shaped track 1432, and the UV lamp adjusting frame is locked to the arc-shaped slot through a screw knob. Specifically, the height adjustment range is ±5 mm, the irradiation surface angle adjustment range is ±10°, and the pitch angle adjustment range is ±5.5°. Among the two UV lamps arranged up and down in each UV lamp assembly 1433, the lower UV lamp is used for UV pre-curing the glue 10 between the Sensor component 7 and the AF lens 8, and the upper UV lamp is used for UV pre-curing the glue 10 between the AF lens 8 and the FF lens 9.

[0086] In the same UV lamp assembly 1433, both UV lamps can be independently adjusted through their irradiation height adjustment module, irradiation surface angle adjustment module, irradiation pitch angle adjustment module, and irradiation horizontal distance adjustment module. The UV lamp adjustment bracket further includes a fixed block, a first inverted L-shaped connecting block, a second inverted L-shaped connecting block arranged in sequence from top to bottom, and a mounting block provided on one side of the second inverted L-shaped connecting block; the irradiation height adjustment module is arranged at the connection between the fixed block and the first inverted L-shaped connecting block; the irradiation surface angle adjustment module is arranged at the connection between the first inverted L-shaped connecting block and the second inverted L-shaped connecting block; the irradiation pitch angle adjustment module is arranged at the connection between the second inverted L-shaped connecting block and the mounting block; the irradiation horizontal distance adjustment module is arranged on the mounting block.

[0087] The irradiation height adjustment module includes a vertically linear waist-shaped hole provided in the middle of the fixed block, and a first screw knob for locking and adjusting the L-shaped horizontal end of the first inverted L-shaped connecting block on the linear waist-shaped hole.

[0090] As Figure 9 ,10 The six axes in the first positioning and clamping mechanism 11 and the second positioning and clamping mechanism 12 are respectively shown. The working principles of the first positioning and clamping mechanism 11 and the second positioning and clamping mechanism 12 are basically the same. The main differences between the two are as follows: The first positioning and clamping mechanism 11 is used to clamp and fix the AF lens 8, and the second positioning and clamping mechanism 12 is used to clamp and fix the FF lens 9. In addition, the second positioning and clamping mechanism 12 is arranged close to the third feeding device 4.

At the same time, the first platform 131 adjusts the displacements in the X-axis, Y-axis, and Z-axis directions under the drive of the second X-axis driving module 133, the second Y-axis driving module 134, and the second Z-axis driving module 135.

[0092] An image acquisition module 136 is provided on one side of the first platform 131, and a first driving module 137 for driving the image acquisition module 136 to be electrically connected to the Sensor component 7.

(It can be replaced according to different products. When replacement is needed, the opening and closing drive module drives the cover plate 53 to open for easy replacement). The image acquisition module 136 transmits the collected target image back to the background program for processing. The background calculates the offset of 6 degrees of freedom using an image quality evaluation algorithm and an attitude prediction algorithm, and feeds the offset back to the motion control system to control the movement of the fixture platform mechanism 13, the first positioning and clamping mechanism 11, and the second positioning and clamping mechanism 12 to achieve the first AA process work.
