Description

technical field [0001] The present invention relates to a camera device, in particular to a security system, a security camera module and a manufacturing method thereof, wherein the security camera module provides a mirror base structure, and the mirror base and the housing of the mirror base structure are integrated In this way, the processing error and assembly error existing between the mirror base and the housing can be greatly reduced and eliminated, thereby improving the imaging quality of the security camera module. Background technique [0002] Compared with other camera modules, the main feature of the security camera module is that it is equipped with a filter switcher, whose function is to enable the security camera module to obtain the information of the environment no matter it is in the daytime or at night. image. [0003] Specifically, figure 1 and figure 2 A prior art security camera module is shown. The security camera module includes a lens 10P, a mirr...

Problems solved by technology

[0004] However, the housings of the mirror holder 20 and the filter switcher 30 of the security camera module in the prior art are separated, that is to say, the mirror holder 20 and the filter switcher The filter 30 needs to be manufactured separately, and then installed by assembling to configure a security camera module. In this process, the separated lens holder 20 and the filter switch 30 produce many question

[0005] Because the mirror base 20 and the filter switcher 30 adopt a separate design, in the process of assembling the security camera module in the prior art, not only the assembly process of the security camera module is increased, but also Also because there are processing errors and assembly errors between the mirror base 20 and the filter switcher 30, when the security camera module is assembled, the mirror base 20 and the filter will be There is a problem of inclination between the switchers 30, which seriously affects the consistency and imaging effect of the security camera module

[0006] In addition, the assembly process of the security camera module in the prior art is to assemble components such as the lens 10P, the mirror holder 20P and the filter switch 30P through mechanical positioning, that is to say, in this In the process, firstly, the lens 10P is mounted on the mirror holder 20P, and then the mirror holder 20P is fixed on the predetermined position of the filter switcher 30P through the mounting element, and then the filter is switched The device 30P is fixed to the predetermined position of the main board 50P by screws, and the positioning of the lens 10P and the photosensitive chip 40P is indirectly realized in this way. However, on the one hand, there is an error in the positioning method of the mechanical positioning, on the other hand, There are also errors between the various components of the security camera module, such a way can easily cause the lens 10P to be not perpendicular to the photosensitive surface of the photosensitive chip 40P, so as to affect the imaging quality of the security camera module

[0007] In addition, each component of the security camera module in the prior art needs to be processed and produced separately, and the filter switcher 30P cannot enter the clean room for processing due to material limitations, which leads to the security The assembly process of the camera module is extremely complicated, which will not only lead to low production efficiency of the security camera module, but also cause internal damage to the security camera module when the security camera module is assembled in a conventional environment. Components are polluted so as to cause contamination points inside the security camera module, thereby affecting the product yield of the security camera module

[0008] In addition, the photosensitive chip 40P is directly mounted on the main board 50P, on the one hand because the heat conduction and heat dissipation performance of the main board 50P is poor, and on the other hand because other electronic components are arranged on the main board 50P , these electronic components will also generate a lot of heat when they are working, so that there will be mutual interference between the electronic components between the photosensitive chip 40P and the main board 50P, so that the photosensitive chip 40P will be affected. the accuracy of

[0009] In addition, when the security camera module is working, the filter switcher 30P needs to be electrically connected to the control circuit, so that the state of the filter switcher 30P can be completed under the control of the control circuit. switch, in the prior art, the filter switcher 30P is connected to the control circuit through wires, but this connection method has a series of problems such as complicated processing, complicated structure and short service life. question
