Description

Technical Field

[0001] The present invention relates to the technical field of camera modules, and in particular to an assembly auxiliary tooling and a non-power-on assembly method of a periscope camera module. Background Art

[0002] In recent years, with the improvement of the performance of consumer electronic devices such as smartphones and tablets, camera modules have become one of the core functions of the devices. Especially in high-end smartphones, the optical zoom function has become one of the important technologies to improve the photo-taking experience. Traditional optical zoom is usually achieved by moving the lens, but this method takes up a lot of space and is difficult to meet the design requirements of increasingly thin mobile phones. Therefore, the periscope camera module came into being. It refracts or reflects light onto the image sensor by designing a reflector or prism, thereby achieving high-magnification optical zoom without increasing the thickness of the device.

[0003] The core principle of the periscope camera module is to use a special optical layout, which usually includes several parts such as optical lens assembly, reflector, image sensor, drive mechanism, etc. The docking accuracy between the reflector and the lens directly affects the optical performance of the module and the final image quality. These modules usually adopt a longitudinal structural design, which effectively controls the thickness of the device and provides a higher zoom ratio.

[0004] China's patent application number CN202221330115.3 discloses a periscope lens driving device, including a prism, a lens carrier for fixing a lens, an integrated base, and a driving unit for the prism and the lens carrier; the prism and the lens carrier are both arranged on the integrated base; the prism is fixed on a prism frame, and the integrated base supports the prism frame through a 3-DOF rotation support mechanism. The integrated base and the prism frame are provided with a driving unit for driving the prism frame to rotate around the X-axis, the Y-axis or the X-axis, the Z-axis respectively, and the driving unit includes a driving coil, a magnet, and a Hall device for detecting the position of the magnet; the magnetic conductive sheet and the magnet are fixed on the moving part, the driving coil is fixed on the stationary part, and the driving unit also includes a magnetic conductive sheet, which is arranged on the side of the magnet away from the driving coil. In this structure, the prism and the lens carrier are both mounted on an integrated base; the alignment process in the assembly process is reduced, the assembly is convenient, the yield is improved, and at the same time, the production cost and the size of the device can be effectively reduced, so as to achieve the purpose of cost saving and miniaturization; the prism is fixed on the prism frame, and the integrated base supports the prism frame through a 3-degree-of-freedom (orthogonal X-axis, Y-axis, and Z-axis) rotation support mechanism.

[0005] In order to realize multi-degree-of-freedom movement of the lens carrier and / or the prism carrier in the periscope motor, the lens carrier and / or the prism carrier need to be connected to the integrated base through a spherical positioning element. This will cause the lens carrier and / or the prism carrier to move when assembling the lens and the prism, affecting the assembly accuracy. Therefore, the existing assembly method of the periscope module is: the clamp of the Lens assembly equipment clamps the Lens or Prism, and the other clamp clamps the periscope VCM (the powered probe on the clamp contacts the Pin of the VCM), the IIC controls the DriverIC to drive and power on (set the DriverIC 0x03 / 0x04 register to control the current supplied to the VCM), the motor is powered on, and the power-on is OK (the VCM realizes the lifting / sinking action of the specified position), and the Lens and Prism components are assembled. The current periscope camera module assembly method requires a periscope motor to be powered on to fix or adjust the lens carrier and the prism carrier, which requires the purchase of corresponding motor power-on assembly equipment, the addition of a power-on corresponding base plate, and the addition of a power-on corresponding fixture, which increases the investment in additional equipment and fixtures, increases the assembly cost, and also increases the assembly process, affecting the assembly efficiency.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] Embodiment 1 Please refer to Figure 1-6, an assembly auxiliary tooling for a periscope camera module is provided, which includes a carrier plate 1, a magnet 2 and a cover plate 3, the carrier plate 1 has a plurality of accommodating cavities 4, the upper end of the accommodating cavity 4 is open, the accommodating cavity 4 is used to position and place an integrated housing 5 of a motor in the periscope camera module, the upper end of the integrated housing 5 of the motor has an open mouth, and a prism carrier 6 and a lens carrier 7 are arranged in the integrated housing 5, the magnet 2 is embedded and installed at the bottom of the accommodating cavity 4, and there are two magnets 2 at the bottom of each accommodating cavity 4, which are respectively connected to the prism The carrier 6 and the lens carrier 7 are arranged correspondingly, and the magnet 2 magnetically attracts the prism carrier 6 and the lens carrier 7, so that the prism carrier 6 and the lens carrier 7 are fitted and fixed to the integrated shell 5. The cover plate 3 is arranged on the top surface of the carrier plate 1 and is crimped to the integrated shell 5. A plurality of through grooves 8 are arranged on the cover plate 3, and the through grooves 8 correspond one by one to the open openings of the integrated shell 5. The cover plate 3 is used for crimping and fixing the integrated shell 5. At the same time, the arrangement of the through grooves 8 facilitates the assembly of prisms and lenses into the prism carrier 6 and the lens carrier 7 in the integrated shell 5.

[0032] The integrated housing 5 used in this example has a built-in driving unit, and drives the prism carrier 6 and the lens carrier 7 to move and adjust the focal length. This part is an existing structure and will not be described in detail here.

[0033] Furthermore, two magnets 2 are arranged on both sides of the bottom end of the accommodating cavity 4. The magnets 2 are permanent magnets or electromagnets. In this example, the magnets 2 are electromagnets. After the integrated housing 5 is placed in the accommodating cavity 4, the electromagnets fix the prism carrier 6 and the lens carrier 7 through electromagnetic attraction to prevent them from moving.

[0034] Furthermore, extension plates 9 are symmetrically provided on the two long sides of the carrier board 1, the upper end surfaces of the extension plates 9 are flush with the upper end surfaces of the carrier board 1, and a positioning groove 10 is provided in the middle of one of the short sides of the carrier board 1. When the carrier board 1 is installed on the assembly platform, the carrier board 1 is embedded and installed on the assembly platform. The extension plates 9 can support the carrier board 1 and fix the carrier board 1 at the same time. The setting of the positioning groove 10 can locate the installation position of the carrier board 1.

[0035] In this example, the top surface of the carrier plate 1 is located outside the accommodating cavity 4 and has three asymmetric threaded holes 11 distributed thereon. The cover plate 3 is provided with a through hole 12 coaxial with the first threaded hole 11. The cover plate 3 is threadedly connected to the threaded hole 11 by bolts passing through the through hole 12. Specifically, two threaded holes 11 are provided on the left end of the carrier plate 1, and one threaded hole 11 is provided on the right side.

[0037] There are eight accommodating cavities 4 and they are distributed in a matrix. The magnets 13 are located outside the four corners of the accommodating cavities 4 and two adjacent accommodating cavities 4 share two magnets 13 at one end. In this way, eight periscope camera modules can be assembled each time. At the same time, the use of magnets 13 can be reduced, which reduces costs. The planar size of the through groove 8 is not less than the planar size of the opening and the cover plate 3 abuts against the four outer corners of the opening of the integrated shell 5. In this example, the structure of the through groove 8 is a cross-shaped structure, which can crimp and fix the integrated shell 5 while increasing the planar size of the through groove 8 to the maximum size to facilitate the placement of prisms and lenses.

Use CCM COB carrying equipment to absorb prisms and lenses and assemble them.

[0039] Furthermore, after the assembly of the prism and the lens is completed, the integrated housing 5 is removed from the carrier board 1, and the external flexible circuit board 14 is assembled, and then a pre-power-on test is performed. The flexible circuit board 14 is electrically connected using a test fixture, and short circuit, open circuit and basic function checks are performed. The camera is powered on by the main control MCU or tester, and the drive response of the autofocus and optical image stabilization motors is checked. After the test is passed, the module is packaged.

[0040] In this example, CCM and COB stand for camera module and chip on board technology respectively. CCM COB-mounted device refers to assembling the CCM camera module in COB packaging and mounting it in various devices to provide visual capture function.

[0041] The working principle of the assembly auxiliary tooling and non-power-on assembly method of the periscope camera module provided by the present invention is as follows: the integrated shell 5 is positioned and placed through the accommodating cavity 4 on the carrier plate 1, and the magnet 2 at the bottom of the accommodating cavity 4 is used to magnetically attract the prism carrier 6 and the lens carrier 7, so that the prism carrier 6 and the lens carrier 7 are sunk and fixed, and the integrated shell 5 is crimped and fixed by the cover plate 3 to fix the periscope motor to prevent the prism carrier 6 and the lens carrier 7 from moving. There is no need to add new equipment. Only the carrier plate 1 with the magnet 2 corresponding to the motor assembly positioning needs to be prepared or ordered.
