Description

Technical Field

[0001] The present invention relates to the technical field of AA alignment equipment, and in particular to an optical axis AA alignment equipment. Background Art

[0002] The optical axis AA alignment device is a technical device used to ensure the relative position of components during the assembly process. During the camera module packaging process, the AA device uses active alignment technology to reduce assembly errors, improve overall efficiency, and ensure the final image quality. It is widely used in the production process of camera modules, especially in the field of mobile phone cameras. There is a huge application demand. Through the AA process technology, the relative positions of image sensors, lens holders, PCBs, lenses and other parts can be accurately aligned, thereby improving the imaging quality and production efficiency of the camera.

As the two sliding blocks continue to move upward inside the corresponding slide groove, the assembled camera is pushed to move upward synchronously on the top of the camera placement seat, so that it is convenient for manual or robotic arms to take up the camera from the top of the camera placement seat, thereby improving the camera unloading efficiency.

[0031] As a technical optimization solution of the present invention, a slide groove 38 is provided on the outer wall of the side where the two second moving rods 27 are close to each other, and a sliding block 39 is installed inside the two slide grooves 38. The ends of the two sliding blocks 39 away from the slide grooves 38 are rotatably installed with a rotating block 40, and the ends of the two rotating blocks 40 away from the slide blocks 39 are rotatably installed with a rotating rod 34.

[0032] As a technical optimization solution of the present invention, cleaning pads 43 are installed on both sides of the outer walls of the two rotating rods 34, a rubber scraper 41 is installed on one side of the outer wall of the two rotating rods 34, and a blower head 42 is installed on the other side of the outer wall of the two rotating rods 34. The two blowers 42 are connected to the external preset air outlet device through a preset hose, so that the wind discharged by the external air outlet device can be transported to the inside of the two blowers 42 through the hose, and discharged from the two blowers 42 to the outside, so as to quickly solidify the glue at the connection between the camera and the lens cover.

[0033] In the present invention, when the user uses the device, the user opens the protective door 2, places the camera and lens cover to be assembled on the top of the camera placement seat 26 and the lens cover placement seat 9 respectively, and controls the first drive motor 11 to drive the first drive screw 10 to rotate, so that the first movable plate 5 can move back and forth on the top of the base 3 and the first track 4, and through the telescopic end of the telescopic end of the telescopic cylinder 14, the second movable plate 6 can be driven to move back and forth on the top of the second track 13, so that the workbench 20 located on the top of the second movable plate 6 can be moved horizontally and vertically inside the equipment body 1, and with the help of the relevant processing equipment preset inside the equipment body 1, the camera is sequentially subjected to the processing steps of PCBA and camera shell assembly, ion activation, dispensing, AA and UV curing, high temperature curing, camera shell and tail line assembly, so that the equipment body 1 can automatically complete the entire assembly work of the camera.

[0034] Before the device body 1 performs glue dispensing operation on the top of the camera, the two sliding blocks 39 can be controlled to move upward inside the corresponding slide groove 38 to a position higher than the camera, and the two rotating rods 34 can be controlled to rotate 90 degrees together, driving the cleaning pad 43 on the outer wall of one side of the rotating rod 34 to rotate to a position close to the camera, and the two rotating blocks 40 are controlled to rotate downward 90 degrees inside the corresponding sliding blocks 39, so that the cleaning pads 43 on the side close to the two rotating rods 34 rotate together to a state of abutting against the top of the camera. As the second driving motor 28 drives the first gear 29 and the second gear 31 to rotate together, the rotating sleeve 30 is driven to rotate synchronously on the surface of the camera placement seat 26, thereby driving the two rotating rods 34 and other multiple different parts to rotate together, so that the two cleaning pads 43 in contact with the top of the camera can automatically clean the part to be glued on the top of the camera during the rotation process, thereby avoiding impurities attached to the top of the camera, which affects the glue dispensing operation.

[0035] After the two cleaning pads 43 clean the top of the camera, the two rotating blocks 40 are controlled to drive the corresponding rotating rods 34 to rotate and reset to the original state. After the glue dispensing device inside the device body 1 has finished dispensing glue on the top of the camera, the lens cover is placed on the top of the camera by the robot inside the device body 1 to make it adhere to the camera. After the glue is cured by the curing device inside the device body 1, the two rotating rods 34 can be controlled to rotate and adjust on the top of the corresponding rotating blocks 40, so that the rubber scrapers 41 set on the outer walls of the two rotating rods 34 rotate to a close position, and the two sliding blocks 39 are controlled to slide upward inside the corresponding slide groove 38, driving the two rotating rods 34 moves upward to the two sides of the camera after bonding, and by controlling the two second driving screws 37 to rotate inside the corresponding grooves 36, the two second moving rods 27 are driven to move in the direction of approaching each other until the rubber scrapers 41 on the side where the two rotating rods 34 are close to each other are in contact with the outer wall of the camera. At this time, the first gear 29, the second gear 31, the rotating sleeve 30 and the two rotating rods 34 are driven by the second driving motor 28 to rotate synchronously, so that the two rubber scrapers 41 can automatically scrape off the glue that overflows from the camera housing and has partially solidified, thereby avoiding the problem that this part of the glue overflows to the outside of the camera has an adverse effect on the assembly quality of the camera.

[0036] At the same time, while the curing device inside the above-mentioned device body 1 cures the glue between the lens cover and the camera, it can also synchronously control the two rotating rods 34 to rotate and adjust, driving the blowing heads 42 on the outer wall of one side of the two rotating rods 34 to rotate and reset to the original state. At this time, the two blowing heads 42 are located on the side close to the two rotating rods 34, and the external preset air outlet device is controlled to start, so that the wind force blown by the two blowing heads 42 acts on the connecting part between the camera and the lens cover, which helps to accelerate the drying and curing of the glue at the connecting part, thereby indirectly improving the efficiency of glue curing during the camera assembly process.

[0037] After the lens cover and the camera are installed, the above-mentioned steps of cleaning the part to be glued on the top of the camera can be repeated before the camera is removed from the top of the camera placement seat 26 for unloading. The cleaning pad 43 on the other side of the two rotating rods 34 is controlled to rotate downward with the help of the corresponding rotating block 40, thereby driving the other two cleaning pads 43 to rotate downward until they are in contact with the top of the lens cover. At this time, the two rotating rods 34 are driven by the rotating sleeve 30 to rotate, so that the other two cleaning pads 43 can automatically clean the surface of the lens after the camera top is installed, which is convenient for improving the cleanliness of the lens surface, reducing the influence of impurities on camera detection, and avoiding impurities adhering to the lens surface, which affects the efficiency of subsequent automatic detection of camera quality.

[0038] In order to facilitate manual or robotic arms to take the assembled camera, after cleaning the lens surface as mentioned above, the two rotating rods 34 and other components can be controlled to rotate and reset to the original state, and the cleaning pads 43 on one side of the two rotating rods 34 can be controlled to rotate to the side close to each other. At this time, the two sliding blocks 39 are controlled to move upward in the corresponding slide grooves 38, driving the two rotating rods 34 to move to the two sides of the camera, and the two second driving screws 37 are controlled to drive the two second moving rods 27 to move in the direction of approaching each other, so that the two rotating rods 34 move in the direction of approaching each other and tightly abut against the outer wall of the camera, which has a clamping and fixing effect on the camera. As the two sliding blocks 39 continue to move upward in the corresponding slide grooves 38, the assembled camera is pushed to move upward synchronously on the top of the camera placement seat 26, so that it is convenient for manual or robotic arms to take the camera from the top of the camera placement seat 26, thereby improving the camera unloading efficiency.

[0039] After the two cleaning pads 43 have been used for a period of time, impurities brought by cleaning the camera and lens surfaces will inevitably adhere to their surfaces. At this time, one of the electric sliders 35 can be controlled to move inside the circular groove 32, driving the first moving rod 33 and other components to move toward the direction of the other first moving rod 33, and controlling the rotating rod 34 on the top of the other first moving rod 33 to rotate so that the rubber scraper 41 set on one side of the other rotating rod 34 rotates to a position close to one of the rotating rods 34, and controlling the two sliding blocks 39 to move upward inside the corresponding sliding groove 38 to a position higher than the camera placement seat 26, and controlling one of the rotating blocks 40 to drive the corresponding rotating rod 34 to rotate downward to a horizontal state. At this time, the cleaning pad 43 on one side of the other rotating rod 34 and the one side of the rotating rod 34 are aligned with each other. The rubber scrapers 41 are in contact with each other, controlling the other sliding block 39 to move up and down inside the corresponding slide groove 38, so that the cleaning pad 43 on one side of the other rotating rod 34 rubs against the rubber scraper 41 on one side of one of the rotating rods 34, thereby automatically scraping off impurities attached to the outer wall of the cleaning pad 43 on the other side of the rotating rod 34. The cleaning pad 43 on the other side can be adjusted by controlling the rotating rod 34 to rotate and clean the impurities on its surface, and then repeat the above steps to scrape and clean the cleaning pad 43 on both sides of one of the rotating rods 34, which is convenient for the subsequent use of the cleaning pad 43. When the staff performs cleaning and maintenance inside the equipment body 1, they can use relevant vacuuming equipment to suck and clean the impurities accumulated inside the shell 8, which is convenient for the normal operation of relevant components inside the shell 8.

[0040] If the workbench 20 needs to be disassembled and the interior of the shell 8 needs to be inspected and maintained, the two pull rods 23 can be pulled together by both hands, driving the two limit blocks 21 to shrink together inside the mounting plate 7, and driving the corresponding return springs 24 to be compressed, and another staff member takes the shell 8 upwards, driving the workbench 20 to be taken out upward from the inside of the mounting groove 19, and the workbench 20 can be quickly disassembled; when the workbench 20 needs to be installed inside the mounting groove 19, only one staff member needs to place the workbench 20 inside the mounting groove 19 and press the workbench 20 downward. During the downward movement of the workbench 20 inside the mounting groove 19, the top arc surface of the two limit blocks 21 can be squeezed, so that the two limit blocks 21 can be stored inside the mounting plate 7 with the help of the contraction of the two return springs 24, until the limit grooves 25 on the outer walls on both sides of the workbench 20 correspond to the limit blocks 21, and the two return springs 24 can be elastically reset to limit and fix the workbench 20 placed inside the mounting groove 19, so as to achieve the effect of quickly installing the workbench 20.
