[0026] Secondly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics contained in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0027] Embodiment

[0028] Reference Figs. 1-4 For the embodiment of the present application, the embodiment provides an automatic centering device of a core taking machine, comprising,

[0029] The bearing mechanism 100 comprises a bearing ring frame 101, an automatic positioning assembly 102 arranged in the inner cavity of the bearing ring frame 101, a positioning seat 103 fixedly installed at the top of the bearing ring frame 101, an electric rod 104 adaptively installed in the inner cavity of the positioning seat 103, and a clamping block 105 fixedly installed at the end of the electric rod 104;

[0030] The soot blowing mechanism 200 comprises a fixed block 201 fixedly installed at the top of the bearing ring frame 101, a damping shock absorber 202 fixedly installed at the top of the fixed block 201, a pipe body 203 fixedly installed at the top of the damping shock absorber 202, a spray head 204 fixedly installed on the outer side of the pipe body 203, and a pressure valve 205 fixedly installed at the top of the pipe body 203.

[0031] The soot blowing mechanism 200 is provided to effectively solve the influence of dust on the lens and the device during the machining process, and the pipe body 203, the spray head 204, the pressure valve 205, and the gas conveying passage 206 and the spray hole 207 constitute a perfect soot blowing system, which ensures the cleanliness of the lens and the normal operation of the device. The integrated design of the bearing mechanism 100 and the soot blowing mechanism 200 makes the device structure compact, occupies small space, is convenient to install and use on the core taking machine, and at the same time, the cooperative work between the components improves the overall performance and working efficiency of the device, and provides a powerful guarantee for the efficient and high-precision machining of the lens.

[0032] Specifically, the soot blowing mechanism 200 further comprises a gas feeding channel 206 formed in the inner cavity of the pipe body 203, a spray hole 207 formed at the joint of the spray head 204 and the pipe body 203, a support column 208 fixedly installed at the bottom of the pipe body 203, a connecting pipe 209 fixedly installed at the outer side of the pipe body 203, and a hose 210 fixedly installed at the end of the connecting pipe 209. The bottom of the support column 208 is fixedly connected with the top of the bearing ring frame 101. The soot blowing mechanism 200 is three groups and is uniformly distributed on the top of the bearing ring frame 101.

[0033] In the process before or during processing, the gas can enter the pipe body 203 through the pressure valve 205, be sprayed from the spray hole 207 through the gas feeding channel 206, and blow away the dust, impurities and the like on the lens surface and inside the device, thereby improving the processing quality. The damper 202 can reduce the vibration generated by the pipe body 203 during gas spraying, avoid the influence of vibration on the centering accuracy of the lens and the stability of the device, and also prolong the service life of the device.

[0034] Further, the automatic positioning assembly 102 comprises a support ring plate 102a fixedly installed in the inner cavity of the bearing ring frame 101, a first telescopic rod 102b fixedly installed at the bottom of the support ring plate 102a, and a first bottom plate 102c fixedly installed at the bottom of the first telescopic rod 102b. The automatic positioning assembly 102 further comprises a first return spring 102d fixedly installed at the top of the first bottom plate 102c, a pressing plate 102e fixedly installed at the top of the first return spring 102d, and a positioning member 102f arranged at the bottom of the bearing ring frame 101.

[0035] The automatic positioning assembly 102 provides the possibility for different specifications of lenses. When different specifications of lenses are placed on the top of the pressing plate 102e, different degrees of pressure will be generated on the pressing plate 102e due to the different weights of the lenses. The larger specification lenses will make the pressing plate 102e press down to a larger extent, while the smaller specification lenses will make the pressing plate 102e press down to a smaller extent. When the pressing plate 102e is pressed down, the first telescopic rod 102b will be retracted and the first return spring 102d will be compressed. The first telescopic rod 102b can be adjusted in length according to the weight and size of the lens, so as to ensure that the lens can be stably placed on the pressing plate 102e. The first return spring 102d can restore the pressing plate 102e to the initial position after the lens is removed, so as to prepare for the next positioning.

[0036] Preferably, the positioning member 102f comprises a shell 102f-1 fixedly installed inside the bearing ring frame 101, a second telescopic rod 102f-2 fixedly installed at the bottom of the shell 102f-1, a second return spring 102f-3 fixedly installed at the bottom of the shell 102f-1, a second bottom plate 102f-4 fixedly installed at the bottom of the second return spring 102f-3, and a rotating shaft 102f-5 rotatably installed outside the second bottom plate 102f-4, and further comprises a positioning arm 102f-6 fixedly installed outside the rotating shaft 102f-5, a positioning sheet 102f-7 fixedly installed at the top of the positioning arm 102f-6, and a limiting rod 102f-8 fixedly installed inside the pressing plate 102e.

[0037] The second telescopic rod 102f-2, the second return spring 102f-3, the rotating shaft 102f-5, the positioning arm 102f-6 and the positioning sheet 102f-7 in the positioning member 102f together form an adaptive positioning structure. When the pressing plate 102e is pressed down, the limiting rod 102f-8 causes the positioning arm 102f-6 to rotate around the rotating shaft 102f-5, thereby adjusting the position of the positioning sheet 102f-7 to adapt to the edge shape and size of lenses of different specifications. For lenses with a larger diameter, the positioning sheet 102f-7 will be opened outward at a certain angle to ensure accurate positioning of the edge of the lens. For lenses with a smaller diameter, the positioning sheet 102f-7 will be retracted inward to achieve accurate positioning as well.

[0038] In use, first place the lens to be processed on the pressing plate 102e of the automatic positioning assembly 102 in the bearing mechanism 100. The weight of the lens causes the pressing plate 102e to be pressed down, driving the first telescopic rod 102b to retract and the first return spring 102d to compress. At the same time, the limiting rod 102f-8 inside the pressing plate 102e acts on the positioning member 102f, causing the positioning arm 102f-6 to rotate around the rotating shaft 102f-5 and the positioning sheet 102f-7 to adaptively adjust its position to match the edge of the lens, thereby achieving preliminary centering.

[0039] Then, the electric rod 104 in the positioning seat 103 pushes the clamping block 105 to further fine-tune the centering of the lens.

[0040] Subsequently, the soot blowing mechanism 200 starts to work. The gas enters the gas delivery channel 206 of the pipe body 203 through the hose 210 and the connecting pipe 209, and is then sprayed out from the spray hole 207 at the connection between the pipe body 203 and the spray head 204, thereby blowing and cleaning the surface of the lens and the inside of the device. In this process, the damping vibration damper 202 reduces the vibration of the pipe body 203, the support column 208 supports the pipe body 203, and the pressure valve 205 controls the pressure and flow of the gas. Finally, after the lens is accurately centered and cleaned, the core taking machine can process the lens.

[0041] In summary, the core taking machine automatic centering device can adapt to different specifications of lenses, without frequent replacement or adjustment of parts of the device for different specifications of lenses, which makes the device have stronger universality and flexibility, can meet the processing needs of various types and specifications of lenses, improves the use efficiency of the equipment, and reduces the production cost.
