It should be noted that the FPC assembly is integrated with a connection pin, an image sensor, a lens holder, and the like. Draw through first LHA laminating equipment and glue in order carrying out the bracket component laminating on the FPC subassembly, draw glue on the microscope base around image sensor promptly, laminate the bracket component. Because the glue is drawn on the mirror base of the FPC assembly through the first LHA laminating equipment, the thermosetting glue is prevented from being stained on the image sensor. In addition, the bracket component includes the combination of motor support and infrared filter, draws gluey in order carrying out the motor subassembly laminating on the bracket component through second LHA laminating equipment, is promptly to draw gluey at the motor support of bracket component, laminates the motor subassembly in the bracket component. Because the motor support in the support component is glued by the second LHA gluing equipment, the thermosetting glue is prevented from being stained on the infrared filter.

Compared with the prior art, do not need independent baking equipment to toast and consolidate, only can realize the solidification of toasting between FPC subassembly, bracket component and the motor subassembly through first LHA laminating equipment and second LHA laminating equipment, saved camera module production equipment cost.
It should be noted that glue is drawn through integrated drawing equipment to LHA laminating equipment in the above-mentioned embodiment, effectively avoided on thermosetting glue pollutes image sensor, the optical lens of camera module, if on inadvertently polluting image sensor or optical lens, can directly with alcohol washing, easy operation is convenient.
Further, the above description explains that the production of the zoom camera module needs to be performed by plasma cleaning, centrifugal cleaning, bracket assembly bonding, and motor assembly bonding. It can be understood that when the camera module production method of the scheme is adopted to produce the fixed-focus camera, the fixed-focus camera does not need a motor for focusing, namely, the fixed-focus camera is cleaned by plasma, centrifugally cleaned, mounted with an infrared filter and mounted with an optical lens, so that the process of the scheme can be omitted. Specific embodiments can refer to the above-mentioned embodiments for the production method of the zoom camera module, and will not be further described here.
In the above embodiments, the core components of the zoom camera module are the FPC assembly having the image sensor and the motor assembly having the optical lens. The optical lens is mainly used for collecting external light and converging the light on the image sensor. The image sensor is mainly used for converting optical signals into electric signals which can be identified by a mobile phone and a computer. The image sensor converts the input optical signal into an electrical signal, outputs the electrical signal through the FPC assembly, and processes the electrical signal through the image processor and the like to store the electrical signal as pictures in JPG, BMP, TIF and other formats.
In this embodiment, the motor assembly includes a threaded voice coil motor and an optical lens, the housing of the motor assembly is generally connected with the FPC assembly through some pins, the FPC assembly can transmit some data to the motor assembly in the process of operating the camera module, and the threaded voice coil motor in the motor assembly is controlled to adjust the position of the optical lens, so as to ensure that the final imaging effect is the effect desired by the user. Generally, if the user does not specifically select the focus position for shooting, the camera module performs focusing according to a built-in algorithm (for example, focusing according to the center position). If a user selects a certain focusing area, the camera module sends a corresponding instruction to the threaded voice coil motor by calculating the relevant information of the selected focusing area, so as to control the movement of the optical lens, and further achieve the function of focusing in a specific area.
In this embodiment, the FPC assembly is a Flexible Printed Circuit Board (FPCB), and may be integrated with an image processor and the like, and is connected to the main component of the camera module through the pins of the image sensor. The flexible printed circuit board is responsible for connecting other components in the camera module with the main controller. The flexible printed circuit board is mainly used for transmitting signals to control the movement of the optical lens to realize focusing and transmitting raw data of the image sensor to the main controller.
In one embodiment, for the closed transmission of each component in the production and assembly process of the camera module, when the sensor detects that the component is transmitted on the conveyor belt, the sensor controls each component transmitted on the conveyor belt to be covered with a closed shell, and the closed space of each closed shell is larger than the volume of the component. Specifically, the FPC assembly transfer between the plasma cleaner and the centrifugal cleaner is explained. Referring to fig. 2, two belts are disposed between the plasma cleaner 10 and the centrifugal cleaner 20, namely a first belt 30 and a second belt 40, the first belt 30 is provided with a movable electromagnet 50, and the second belt 40 is used for transferring the FPC assembly 70 from the plasma cleaner 10 to the centrifugal cleaner 20. When the electromagnet 50 is powered on, the metal dust cover 60 can be attracted by magnetism, and when the electromagnet is powered off, the metal dust cover 60 falls onto the second conveyor belt 40 to cover the FPC assembly 70 on the second conveyor belt 40.
