Description

[0002] With the popularity of smart home devices, intelligent visual doorbells have gradually become an important part of access control security. The intelligent visual doorbell usually integrates a camera assembly for video acquisition and real-time monitoring. In the production and assembly process of the camera assembly, in order to ensure the imaging clarity, focusing operation is usually required before leaving the factory. The essence of focusing operation is to rotate the lens in the camera assembly to accurately adjust the relative position between the lens and the imager, so as to achieve accurate matching of the focal length. The quality of focusing is directly related to the imaging effect and user experience of the device in actual use, so the focusing process is of great significance in the production test link.

[0003] The existing focusing method of the camera assembly mostly relies on manual operation.

[0032] Refer to Figure 1 And Figure 2The positioning mechanism 2 comprises a first fixed frame 24, a first moving module 21, a lifting cylinder 22 and a floating platform 25. The first fixed frame 24 and the first moving module 21 are adjacently arranged and fixedly installed on the top surface of the electric turntable 11. The lifting cylinder 22 is arranged on the first moving module 21. The floating platform 25 is installed on the top surface of the first fixed frame 24. The piston rod of the lifting cylinder 22 is connected with a pressing plate 23. A through slot 251 is formed in the floating platform 25. The camera assembly 3 is arranged in the through slot 251 of the floating platform 25. An electronic interface 26 is installed on the bottom surface of the first fixed frame 24. The electronic interface 26 is vertically arranged. The top end of the electronic interface 26 penetrates through the top surface of the first fixed frame 24 and is located directly below the through slot 251. In the implementation, before the camera assembly 3 is tested for focusing, the camera assembly 3 is first placed at the through slot 251 of the floating platform 25. The first moving module 21 is controlled to move horizontally to one side of the floating platform 25. The lifting cylinder 22 is controlled to drive the pressing plate 23 to press the camera assembly 3 on the floating platform 25 tightly, and at the same time, the camera assembly 3 is connected with the electronic interface 26, so that the positioning of the camera assembly 3 is completed, and the power supply and communication are provided. Through the arrangement of the above-mentioned positioning mechanism 2, after the camera assembly 3 is placed in the through slot 251 of the floating platform 25, the camera assembly 3 can be reliably pressed and fixed under the driving of the lifting cylinder 22, and at the same time, the accurate butt joint of the camera assembly 3 and the electronic interface 26 is ensured, so that the power supply and communication connection are realized while the physical positioning is completed. The structure not only ensures the stability and reliability of the camera assembly 3 in the subsequent focusing test process, but also reduces the manual plugging operation, and improves the automation degree and efficiency of the test link. In addition, after the positioning is completed, the camera assembly 3 is remotely controlled to start.

[0033] With reference to Figure 1 and Figure 2 A second fixed frame 12 is arranged on the workbench 1 and located at the side of the electric turntable 11. A camera 4 is fixedly installed on the second fixed frame 12. The camera 4 is used to obtain the camera distance parameter of the camera assembly 3, i.e. the distance from the upper surface of the camera to the upper surface of the carrier, when the camera assembly 3 is rotated to the side of the camera 4.

[0034] With reference to Figure 1 and Figure 3The focusing mechanism 5 comprises a third fixed frame 51, a second moving module 52 and a mounting plate 53. The third fixed frame 51 is fixedly installed on the side of the electric turntable 11. The second moving module 52 is arranged at the top end of the third fixed frame 51. The mounting plate 53 is horizontally arranged on the second moving module 52. A through hole is formed in the mounting plate 53. The test drawing is located directly above the through hole. A cross roller bearing 531 is installed at the inner side wall of the through hole. A first rotary motor 54 and a driving cylinder 58 are arranged on the mounting plate 53. A large synchronous wheel 56 is connected to the bottom surface of the cross roller bearing 531. The driving cylinder 58 is floatingly arranged on the bottom surface of the large synchronous wheel 56. A clamping jaw 59 is connected to the output end of the driving cylinder 58. A small synchronous wheel 55 is connected to the output end of the first rotary motor 54. The large synchronous wheel 56 and the small synchronous wheel 55 are drivingly connected through a belt 57. In the implementation, after the camera assembly 3 is conveyed to the working position of the focusing mechanism 5 by the electric turntable 11, the second moving module 52 drives the mounting plate 53 to descend to the position above the camera assembly 3. Then, the driving cylinder 58 is started to control the clamping jaw 59 to clamp the camera assembly 3. Then, the first rotary motor 54 is started to drive the small synchronous wheel 55 at the output end thereof to rotate. The small synchronous wheel 55 drives the large synchronous wheel 56 to rotate through the belt 57. The large synchronous wheel 56 further drives the cross roller bearing 531 to rotate, so as to realize the rotation operation of the clamping jaw 59 on the camera assembly 3, to complete the focal length adjustment. After the focusing is completed, the camera assembly 3 is controlled remotely to shoot the test drawing located directly above the through hole, to detect and judge the imaging definition. If the test fails, the camera assembly 3 is manually sent to the defective product track. Through the support of the cross roller bearing 531, the high precision and stability of the rotation of the large synchronous wheel 56 and the clamping jaw 59 are realized. The belt 57 transmission structure between the small synchronous wheel 55 and the large synchronous wheel 56 not only enables the power of the rotary motor to be efficiently transmitted to the clamping jaw 59, but also can buffer the impact force in the rotation process, to ensure the stability of the focusing operation. The cooperation of the driving cylinder 58 and the clamping jaw 59 enables the camera assembly 3 to be firmly clamped during the focusing process, to avoid the inaccuracy of focusing caused by looseness. At the same time, the test drawing is arranged directly above the through hole, to realize the instant detection after the focusing is completed, so as to ensure the closed-loop control of the focusing operation, to improve the focusing efficiency and the consistency of the finished products.

[0035] Referring to Figure 1 and Figure 4The dispensing mechanism 6 comprises a fourth fixed frame 65, an x-axis moving module 61, a y-axis moving module 62, and a z-axis moving module 63. The fourth fixed frame 65 is fixedly installed on the side of the motorized turntable 11. The y-axis moving module 62 is arranged on the fourth fixed frame 65. The x-axis moving module 61 is arranged on the y-axis moving module 62. The z-axis moving module 63 is arranged on the x-axis moving module 61. A second rotary motor 64 is arranged on the z-axis moving module 63. A rotary platform 66 is connected to the output end of the second rotary motor 64. A dispensing valve 672 connected to a glue pipe 671 is arranged on the rotary platform 66. In combination with Figure 5 A glue discharging platform 68 is arranged on one side of the fourth fixed frame 65. A glue wiping platform 69 is also arranged on one side of the fourth fixed frame 65. A glue wiping inlet 691 is arranged on the glue wiping platform 69 for the dispensing valve 672 to enter. In implementation, after the camera assembly 3 is sent to the dispensing position by the motorized turntable 11, the y-axis moving module 62 drives the x-axis and z-axis moving modules 63 and the dispensing module 67 to be positioned in the horizontal direction as a whole. The x-axis moving module 61 further adjusts the transverse position of the dispensing module 67. Then, the z-axis moving module 63 drives the second rotary motor 64 to drive the rotary platform 66 to descend, so that the dispensing valve 672 moves to the position above the target position of the camera assembly 3. The dispensing valve 672 opens under the control instruction to accurately coat the glue delivered from the glue pipe 671 on the outer circumferential position of the camera assembly 3, so as to fix the focal length of the lens. After dispensing, the dispensing module 67 can be moved to the glue discharging platform 68 to discharge the remaining glue, or be moved to the glue wiping platform 69 to clean the residual glue through the glue wiping inlet 691, so as to ensure the cleanliness of the glue outlet of the dispensing valve 672 and the stability of subsequent dispensing. Through the cooperation of the x-axis, y-axis, and z-axis moving modules, the dispensing module 67 can be flexibly positioned in the three-dimensional direction in space, so as to ensure the accuracy of the dispensing position. The second rotary motor 64 and the rotary platform 66 are arranged, so that the dispensing module 67 can adjust the angle as needed to adapt to the dispensing operation of different positions, thereby enhancing the process adaptability. The glue discharging platform 68 and the glue wiping platform 69 are arranged, so that the dispensing valve 672 can discharge the remaining glue and clean before and after dispensing, effectively preventing blockage and glue pollution, and improving the stability and consistency of the dispensing process, thereby ensuring the assembly quality of the camera assembly 3 in the batch production process.

[0036] Referring to Figure 1 and Figure 6The curing mechanism 7 includes a fifth fixing frame 71, a first air cylinder 72 and a second air cylinder 73. The fifth fixing frame 71 is located at the periphery of the motorized turntable 11. The first air cylinder 72 is arranged on the fifth fixing frame 71. The second air cylinder 73 is arranged on the first air cylinder 72. The first curing lamp 74 and the second curing lamp 75 are installed on the second air cylinder 73. The first curing lamp 74 and the second curing lamp 75 are arranged in a cross manner. The first curing lamp 74 and the second curing lamp 75 are respectively inclined in different directions and form an included angle between the heads of the two lamps. In the implementation, after the camera assembly 3 is completed by the dispensing, the first air cylinder 72 drives the second air cylinder 73 to rise, and then the second air cylinder 73 drives the first curing lamp 74 and the second curing lamp 75 to move to the camera assembly 3 for curing. Through the structural design of the curing mechanism 7, the combination of the first air cylinder 72 and the second air cylinder 73 enables the curing lamp to realize flexible lifting and position adjustment, so as to quickly and accurately move to the top of the camera assembly 3 for curing operation. The first curing lamp 74 and the second curing lamp 75 are arranged in a cross and inclined manner and form an included angle between the lamp heads. The camera assembly 3 is located in the intersection area of the two curing light beams, so that the part coated with glue can be irradiated from different directions at the same time. This structure not only improves the uniformity and fullness of the glue curing, avoids the incomplete curing caused by single irradiation direction, but also shortens the curing time, improves the process efficiency and product consistency.

[0037] In summary, by arranging the positioning mechanism 2, the camera 4, the focusing mechanism 5, the dispensing mechanism 6 and the curing mechanism 7 on the motorized turntable 11 in sequence, a set of continuous focusing and fixing procedures are formed. In the implementation process, the camera assembly 3 is first connected with power supply and communication by the positioning mechanism 2. The camera 4 automatically acquires the camera distance parameter. The focusing mechanism 5 drives the jaw 59 to rotate the camera assembly 3 for focusing in combination with the parameter, and completes the focusing effect detection with the assistance of the test drawing. Then, the dispensing mechanism 6 coats the camera assembly 3 after focusing with glue. The curing mechanism 7 cures the glue. Through this semi-automatic way, the traditional focusing mode relying on manual observation and manual rotation is avoided. The dependence on the experience and manual precision of the operator is greatly reduced. The working efficiency is improved, the production rhythm is shortened, and the technical problems of the existing manual focusing mode, such as low efficiency, poor stability and difficulty in meeting the needs of large-scale production, are effectively solved.
