[0015] See also Figures 1 to 7 The embodiment of the present application provides a core aligning machine, including a frame 1 and a lower detection mechanism 2, a core aligning mechanism 3 and a detection lens group 4 arranged on the frame 1 in sequence from bottom to top; the lower detection mechanism 2 includes a lifting platform 21 vertically movably connected to the frame 1, a lifting drive device 22 for driving the lifting platform 21 to move up and down, a detection platform 23 fixedly installed on the lifting platform 21, and an in-and-out assembly 24 installed on the lifting platform 21 for driving the lens 5 to move to the detection platform 23; the core aligning mechanism 3 includes a mounting plate 31, an XY slide 32 fixedly installed on the frame 1 for driving the mounting plate 31 to move along the X-axis or Y-axis direction, and three ejector assemblies 33 arranged on the mounting plate 31; the mounting plate 31 has a movable hole 311, and the three ejector assemblies 33 are spaced apart in the movable hole along the circumferential direction. Next to 311, the ejector assembly 33 includes a needle shell 331, a movable needle 332 linearly connected in the needle shell 331, a spring 333 installed in the needle shell 331 and with both ends supporting the needle shell 331 and the movable needle 332, and a telescopic slide 334 fixedly installed on the mounting plate 31 for driving the needle shell 331 to move telescopically; when the lifting platform 21 rises, it can move the lens 5 upward to the movable hole 311; the light source provided by the detection platform 23 can form an image on the detection lens group 4 above through the lens 5; when the three telescopic slides 334 are extended, they can respectively push the three movable needles 332 from the outside of the lens 5 through the three pinholes 53 of the lens seat 51, enter the inside of the lens 5 and support the lens 52, and when the XY slide 32 moves, the three movable needles 332 can move with the lens 52 in a plane. Among them, the spring 333 plays a buffering role for the movable needle 332.

[0016] The alignment machine penetrates into the lens 5 through three movable pins 332 and supports the lens 52, and drives the lens 52 to align through the movement of the XY slide table 32. In this way, the lens 52 located inside the lens 5 can be aligned, and the degree of automation is high.

[0017] The in-and-out assembly 24 includes a placement plate 241 for placing the lens 5 and a linear module 242 for driving the placement plate 241 and the lens 5 thereon to move obliquely downward from top to bottom onto the detection table 23. The linear module 242 is arranged to be inclined downward from top to bottom during the extension from front to back. The linear module 242 is arranged to be inclined so that the lens 5 first moves obliquely downward onto the detection table 23 and then rises. This arrangement is to ensure that the placement height of the lens 5 when loading is in accordance with the height of the human body.

[0018] The mounting plate 31 is also fixed with a plurality of UV curing lamps 34 which are spaced apart along the circumferential direction beside the movable hole 311. UV glue is pre-dotted in the three glue dispensing holes 54 of the lens 5.

[0022] The following briefly describes the working process and use method of the alignment machine in the above embodiment: The lens 5 is placed on the placement plate 241. The placement plate 241 moves obliquely downward under the drive of the linear module 242, thereby moving the lens 5 to the top of the detection platform 23. The lifting platform 21 rises and moves the lens 5 to the movable hole 311. The movable needles 332 of the three ejector pin assemblies 33 extend, so that the three pinholes 53 of the lens 5 penetrate therein and push onto the lens 52. The light source and the detection pattern provided by the detection platform 23 are imaged on the detection lens group 4 through the lens 5. According to the imaging information, the XY slide 32 moves back and forth with the three movable needles 332 or the lens 52 to adjust the center. After the lens 5 is adjusted, the movable needle 332 retracts, and the UV curing lamp 34 is started to irradiate the UV glue in the glue dispensing hole 54 to solidify it. Then the lifting platform 21 descends, and the placement plate 241 moves obliquely upward, and the lens 5 that has completed the center adjustment is taken out and another lens 5 is put in.
