Description

Technical Field

[0001] This application relates to the field of camera assembly technology, and in particular to an automatic assembly device for a video doorbell camera. Background Technology

[0002] With the popularization of smart home and security monitoring technologies, video doorbells have gradually become common security devices in residences, office buildings, and other places. Video doorbells are usually composed of components such as a main control circuit board, a camera module, a display screen, and a power module. Among them, the connection between the camera module and the main control circuit board is the key link to realize image acquisition and processing.

[0003] In existing assembly processes, camera modules typically come with a protective film at the factory to prevent contamination from dust, scratches, and other damage during transportation and storage. During assembly, the protective film must first be removed, and the camera module must be accurately placed in its designated position on the motherboard before being secured to the motherboard with at least two screws. These operations are generally performed manually. Due to the numerous steps involved, manual handling of tasks such as picking up and placing the camera, removing the protective film, positioning, and screwing in the screws can easily lead to instability, resulting in low assembly efficiency and difficulty in ensuring consistent product quality. Summary of the Invention

[0004] To ensure the efficiency, stability, and product quality of the assembly process, this application provides an automated assembly device for video doorbell cameras. The technical solution provided in this application is as follows: An automatic assembly device for a video doorbell camera includes a workbench. One side of the workbench is equipped with a hopper, a robotic arm, a positioning mechanism, a conveying mechanism, and a film-removing mechanism. The robotic arm retrieves a camera module from the hopper and places it on the conveying mechanism. The conveying mechanism places the camera module on the positioning mechanism. The film-removing mechanism removes the film from the camera module. The other side of the workbench is equipped with an electric turntable and an assembly station on the turntable. The circumference of the electric turntable, in a counter-clockwise direction, is sequentially equipped with a first conveying module, a loading station, a first mounting mechanism, a second mounting mechanism, and a second conveying module. The robotic arm also places the film-removed camera module on the assembly station. The first conveying module places the motherboard from the loading station on the assembly station. The first and second mounting mechanisms are used for screw assembly, and the second conveying module is used for unloading.

[0005] In one specific implementation, the conveying mechanism includes a base, a conveying motor, and a conveying cylinder. The base is located on one side of the robotic arm and the hopper. The conveying motor is located on the base. The conveying cylinder is located at the output end of the conveying motor. The output end of the conveying cylinder is connected to a conveying gripper.

[0006] In one specific implementation scheme, the positioning mechanism includes a positioning frame, a positioning platform, and a positioning cylinder. The positioning frame is disposed between the conveying mechanism and the film-tearing mechanism, the positioning platform is disposed on the positioning frame, and the positioning cylinder is disposed on the positioning platform. The output end of the positioning cylinder is connected to a first positioning block and a second positioning block.

[0007] In one specific implementation, the film-tearing mechanism includes a horizontal motion module, a lifting motion module, a drive cylinder, and a discharge hopper. The discharge hopper is located between the horizontal motion module and the positioning frame. The lifting motion module is located on the horizontal motion module. The drive cylinder is located on the lifting motion module. The output end of the drive cylinder is connected to a first gripper.

[0008] In one specific implementation, a vacuum generator is connected to the bottom of the discharge hopper.

[0009] In one specific implementation, the film-tearing mechanism further includes a fixing plate disposed on one side of the discharge hopper, and an electrostatic eliminator is provided at the top of the fixing plate.

[0010] In one specific implementation, a photoelectric sensor is provided at the top of the fixing plate, and the photoelectric sensor is located on one side of the static eliminator.

[0011] In one specific implementation, the first mounting mechanism includes a first screwdriver, a first camera, and a first pressing cylinder. The first screwdriver is located around the electric turntable, the first camera is located on the first screwdriver, and the first pressing cylinder is located on one side of the first screwdriver. The output end of the first pressing cylinder is connected to a first pressure plate, which is used to press the main board.

[0012] In one specific implementation, the second mounting mechanism includes a second screw gun, a second camera, and a second pressing cylinder. The second screw gun is located on the periphery of the electric turntable, the second camera is located on the second screw gun, and the second pressing cylinder is located on one side of the second screw gun. The output end of the second pressing cylinder is connected to a second pressure plate, which is used to press the main board.

[0013] In one specific implementation scheme, the workbench is further provided with a transfer station, a third transport module, a material unloading station, and a defective product track. The second transport module is used to place the assembled camera module and motherboard at the transfer station, and the third transport module is used to select whether to place the assembled camera module and motherboard at the material unloading station or the defective product track according to the assembly effect.

[0014] In summary, the beneficial effects of this application include at least the following: 1) Through the coordinated operation of the horizontal motion module, the lifting motion module, and the drive cylinder, the protective film of the camera module can be accurately gripped and stably removed, ensuring the controllability and repeatability of the film removal action. With the help of photoelectric sensors to detect the film removal result in real time, it is possible to promptly identify whether there are residual film pieces, preventing defective assembly from flowing into subsequent processes. At the same time, the electrostatic eliminator and vacuum generator are used together to ensure that the torn film pieces can be quickly detached from the grippers and effectively recycled by the discharge hopper after being peeled off. This not only reduces the risk of secondary pollution caused by film scattering, but also improves the cleanliness of the working environment and the reliability of production.

[0015] 2) By using a pressure plate driven by a downward cylinder to reliably press the motherboard and camera module before screwing, assembly deviations caused by loose parts during screw tightening can be effectively avoided. Combined with the camera taking pictures for positioning and inspection before and after screwing, not only can the screw position be accurately corrected to ensure the accuracy of the screwing action, but the screw fastening quality can also be judged in real time after assembly, thereby timely identifying assembly defects and guiding them to the defective product track, ensuring the stability, consistency and quality of the product assembly process.

[0016] The entire system comprises a hopper, a robotic arm, a conveying mechanism, a positioning mechanism, a film-removing mechanism, and multiple workstations on an electric turntable working in tandem. The robotic arm handles the loading and unloading of camera modules, the conveying and positioning mechanisms ensure accurate module positioning, the film-removing mechanism removes the protective film from the camera modules, and the electric turntable sequentially transfers the assembly station to the motherboard loading, screw tightening, and quality inspection stages. Through pressing, camera alignment detection, and defective product sorting, the system ultimately achieves stable screw fixing of the camera module to the motherboard. This automated process solves the problems of low efficiency, insufficient assembly accuracy, and poor product consistency caused by relying on manual processes for camera film removal, positioning, and multi-point screw assembly in existing technologies, thereby ensuring high efficiency, stability, and product quality in the assembly process.

[0027] This application discloses an automatic assembly device for a video doorbell camera.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The automatic assembly equipment for video doorbell cameras includes a workbench 1. One side of the workbench 1 is equipped with a hopper 9, a robotic arm 8, a positioning mechanism 6, a conveying mechanism 3, and a film-removing mechanism 2. The robotic arm 8 is used to remove camera modules from the hopper 9 and place them on the conveying mechanism 3. The conveying mechanism 3 is used to place the camera modules on the positioning mechanism 6. The film-removing mechanism 2 is used to remove the film from the camera modules. The other side of the workbench 1 is equipped with an electric turntable 11 and an assembly station 14 on the electric turntable 11. Around the circumference of the electric turntable 11, in a counter-clockwise direction, are arranged a first conveying module 12, a loading station 13, a first mounting mechanism 4, a second mounting mechanism 5, and a second conveying module 15. The robotic arm 8 is also used to place the film-removed camera modules on the assembly station 14. The first conveying module 12 is used to place the motherboard from the loading station 13 above the camera modules on the assembly station 14. The first mounting mechanism 4 and the second mounting mechanism 5 are used to assemble the camera modules and motherboards with screws. The workbench 1 is also equipped with a transfer station 17, a third transport module 16, a material unloading station 18, and a defective product track 19. The second transport module 15 is used to place the assembled camera module and motherboard in the transfer station 17. The third transport module 16 is used to select whether to place the assembled camera module and motherboard in the material unloading station 18 or the defective product track 19, depending on whether there is an assembly error.

[0029] Reference Figure 3 The conveying mechanism 3 includes a base 31, a conveying motor 34, and a conveying cylinder 33. The base 31 is located on the workbench 1, on one side of the robotic arm 8 and the hopper 9. The conveying motor 34 is fixedly mounted on the base 31, and the conveying cylinder 33 is mounted on the output end of the conveying motor 34. The output end of the conveying cylinder 33 is connected to a conveying gripper 32. After the robotic arm 8 takes the camera module out of the hopper 9, it places it on the conveying gripper 32, which is clamped by the conveying cylinder 33. Then, the conveying motor 34 is started to rotate the conveying gripper 32 ninety degrees, so that the camera module is placed on the positioning mechanism 6, and the film on the camera module is positioned upwards.

[0030] Reference Figure 3 and Figure 4 The positioning mechanism 6 includes a positioning frame 61, a positioning platform 62, and a positioning cylinder 63, combined with... Figure 1 The positioning frame 61 is fixedly installed between the transport mechanism 3 and the film-tearing mechanism 2. The positioning platform 62 is fixedly installed on the top surface of the positioning frame 61. The positioning cylinder 63 is installed on the side wall of the positioning platform 62. The output end of the positioning cylinder 63 is connected to the first positioning block 64 and the second positioning block 65. After the transport mechanism 3 places the camera module on the positioning platform 62, it controls the positioning cylinder 63 to clamp the camera module with the first positioning block 64 and the second positioning block 65, thereby completing the positioning.

[0031] Reference Figure 1 and Figure 3 The film-tearing mechanism 2 includes a horizontal motion module 21, a lifting motion module 22, a drive cylinder 23, and a discharge hopper 29, combined with... Figure 4 The discharge hopper 29 is fixedly installed between the horizontal motion module 21 and the positioning frame 61. The lifting motion module 22 is installed on the horizontal motion module 21, and the drive cylinder 23 is installed on the lifting motion module 22. The output end of the drive cylinder 23 is connected to the first gripper 24. The film-tearing mechanism 2 also includes a fixing plate 25, which is vertically set on one side of the discharge hopper 29. The top of the fixing plate 25 is equipped with an electrostatic eliminator 26 and a photoelectric sensor 27, and the bottom of the discharge hopper 29 is connected to a vacuum generator 28. In implementation, after the camera module is fixed on the positioning platform 62, the horizontal motion module 21 is controlled to move the first gripper 24 to the camera module. Then, the drive cylinder 23 is controlled to make the first gripper 24 clamp the film. Subsequently, the lifting motion module 22 is started to move the first gripper 24 upward to complete the film-tearing operation. Subsequently, photoelectric sensor 27 detects whether the film removal is complete, specifically whether film is present on the first gripper 24. If so, vacuum generator 28 and static eliminator 26 are activated. Static eliminator 26 blows out plasma air, which, combined with vacuum adsorption, ensures that the removed film is collected by discharge hopper 29 as much as possible. Through the coordinated operation of horizontal motion module 21, lifting motion module 22, and drive cylinder 23, accurate gripping and stable removal of the protective film for the camera module can be achieved, ensuring the controllability and repeatability of the film removal action. Photoelectric sensor 27 monitors the film removal result in real time, promptly identifying any residual film and preventing defective assembly from flowing into subsequent processes. Simultaneously, the use of static eliminator 26 in conjunction with vacuum generator 28 ensures that the removed film quickly detaches from the gripper and is effectively collected by discharge hopper 29 after being peeled off, reducing the risk of secondary contamination caused by film scattering and improving the cleanliness of the working environment and the reliability of production.

[0032] Reference Figure 1 and Figure 2The first mounting mechanism 4 includes a first screwdriver 41, a first camera 42, and a first pressing cylinder 43. The first screwdriver 41 is located around the electric turntable 11, the first camera 42 is mounted on the first screwdriver 41, and the first pressing cylinder 43 is located on one side of the first screwdriver 41. The output end of the first pressing cylinder 43 is connected to a first pressure plate 44, which is used to press the main board. The second mounting mechanism 5 includes a second screwdriver 51, a second camera 52, and a second pressing cylinder 53. The second screwdriver 51 is located around the electric turntable 11, the second camera 52 is mounted on the second screwdriver 51, and the second pressing cylinder 53 is located on one side of the second screwdriver 51. The output end of the second pressing cylinder 53 is connected to a second pressure plate 54, which is used to press the main board. Since the first mounting mechanism 4 and the second mounting mechanism 5 are set up and operated in the same way, the following explanation will only take the first mounting mechanism 4 as an example. In practice, the first screw gun 41 can move along the x, y, and z axes. When the assembly station 14 rotates to the first mounting mechanism 4, the first pressing cylinder 43 is activated to drive the first pressure plate 44 to firmly press the motherboard and camera module, so that it is not easy to loosen during the screw-driving operation. Then, the first camera 42 is used to take pictures for alignment. Based on the alignment of the first camera 42, the first screw gun 41 is moved and the screw assembly operation is performed. After assembly, the camera is used again to take pictures to check whether the screws are assembled well. If there is a problem with the assembly, it needs to be sent to the defective product track 19. By using a pressure plate driven by a downward-pressing cylinder to reliably clamp the motherboard and camera module before screwing in the screws, assembly deviations caused by loose parts during screw tightening can be effectively avoided. Combined with the camera taking pictures for positioning and inspection before and after screwing in, not only can the screw position be accurately corrected to ensure the accuracy of the screwing action, but the screw fastening quality can also be judged in real time after assembly, thereby timely identifying assembly defects and guiding them to the defective product track 19, ensuring the stability, consistency and quality of the product assembly process.

[0033] In summary, the equipment is based on a workbench 1. On one side of the workbench 1 are a hopper 9, a robotic arm 8, a conveying mechanism 3, a positioning mechanism 6, and a film-tearing mechanism 2. On the other side is an electric turntable 11 and multiple workstations distributed around it. Specifically, the robotic arm 8 is used to remove camera modules with protective films from the hopper 9 and, in conjunction with the conveying mechanism 3, places them on the positioning mechanism 6. After the positioning mechanism 6 clamps and positions the camera modules, the film-tearing mechanism 2 accurately grips and stably removes the protective film from the surface of the camera modules. Simultaneously, through sensor detection and electrostatic elimination combined with vacuum adsorption, the film is effectively recycled, preventing residual film from entering subsequent processes. After the film is removed, the robotic arm 8 moves the camera module to the assembly station 14 on the electric turntable 11. The electric turntable 11 rotates sequentially to the motherboard loading station 13, the first mounting mechanism 4, and the second mounting mechanism 5. The motherboard is placed above the camera module by the transport module. The screw installation is achieved by pressing down on the pressure plate to ensure stable positioning of the camera module and the motherboard. Combined with camera alignment and detection, the screw gun can accurately tighten multiple screws and judge the tightening quality in real time. Finally, the assembled parts are sent to the transfer station 17 via the turntable, and the transport module selects whether to enter the unloading station 18 or the defective product track 19, realizing the separation of good and defective products.

[0034] Through the coordinated efforts of the aforementioned mechanisms, the entire process of camera module assembly, from material handling, positioning, film removal, assembly to screw tightening and inspection, is fully automated. This solves the problem of existing technologies that rely heavily on manual labor for film removal, positioning, and screw fixing. Manual methods are not only inefficient but also prone to operational errors, leading to inaccurate camera module positioning, poor screw tightening, and film residue, resulting in unstable and inconsistent product quality. The introduction of automated structural design and visual inspection significantly improves assembly efficiency, ensures operational stability and repeatability, and effectively enhances product consistency and overall assembly quality.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
