The motor 215 can drive the driving wheel 216 to rotate, and the synchronous belt 214 follows the driving wheel 216 to rotate, so as to drive the left centering assembly 21 and the right centering assembly 22 to approach or separate from each other.

[0051] Preferably, the left centering assembly 21 includes a left connecting plate 218, and the right centering assembly 22 includes a right connecting plate 223. The position where the calibration jig is installed on the left connecting plate 218 or / and the right connecting plate 223 is a restricted structure, and the restricted structure restricts the calibration jig from moving outward to the product to be centered.

Of course, the front end of the left connecting plate 218 or / and the front end of the right connecting plate 223 can also be a restricted structure. Therefore, the restricted position 230 that restricts the movement of the calibration jig can be on the side of the left connecting plate 218, or on the side of the right connecting plate 223, or both the left connecting plate 218 and the right connecting plate 223 can be provided with the restricted position 230, or the positions where the left connecting plate 218 or / and the right connecting plate 223 install the calibration jig can be non-restricted structures, not limited by this description, as long as it can meet the actual requirements and the shape of the calibration jig.

Of course, if the right connecting plate 223 is not a restrictive structure, the top of the right alignment jig 211 can also be in a double-ended V shape or a single-ended top V shape, or the shape of the top of the alignment jig can be changed according to the centering product to match the shape of the centering product M.

[0056] Preferably, the left centering assembly 21 includes a left slider 220;

[0057] The left slider 220 is slidably mounted on the guide rail 202. The left slider 220 is connected to the left connecting plate 218. The left connecting plate 218 is connected to the left fixing plate 221, the left pressing plate 222, and the left alignment jig 210. A synchronous belt 214 is provided between the left fixing plate 221 and the left pressing plate 222, and the left fixing plate 221 is connected to the left pressing plate 222.

[0058] As another example, a synchronous belt 214 is provided between the left connecting plate 218 and the left pressing plate 222, and the left connecting plate 218 is connected to the left pressing plate 222.

[0059] Preferably, the right centering assembly 22 includes a right slider 224;

[0060] In the right centering assembly 22, the right slider 224 is slidably mounted on the guide rail 202. The right slider 224 is connected to the right connecting plate 223. The right connecting plate 223 is respectively connected to the right fixing plate 225, the right pressing plate 226, and the right alignment jig 211. A synchronous belt 214 is provided between the right fixing plate 225 and the right pressing plate 226, and the right fixing plate 225 is connected to the right pressing plate 226.

[0061] As another example, a synchronous belt 214 is provided between the right connecting plate 223 and the right pressing plate 226, and the right connecting plate 223 is connected to the right pressing plate 226.

[0062] In this embodiment, a first origin coordinate switch 219 is provided below the right connecting plate 223. As another example, a first origin coordinate switch 219 is provided below the left connecting plate 218; Furthermore, a left gasket 212 is provided on the left alignment jig 210, and a right gasket 213 is provided on the right alignment jig 211; As another example, the left gasket 212 and the right gasket 213 may not need to be installed on the alignment jig.

[0063] Preferably, the left centering assembly 21 and the right centering assembly 22 are connected to any two points of the synchronous belt 214.

[0064] The working principle of the device provided in this embodiment is as follows:

[0065] As Figure 5As shown, the distance a is the distance from the right fixed plate 225 to the vertical center line, the distance b is the distance from the left fixed plate 221 to the vertical center line, and the lengths of the distance a and the distance b are equal; the positive rotation mode is that the driving wheel 216 rotates counterclockwise, and at this time, the synchronous belt 214 is driven to rotate counterclockwise; the reverse rotation mode is that the driving wheel 216 rotates clockwise, and at this time, the synchronous belt 214 is driven to rotate clockwise.

[0066] When the driving wheel 216 rotates in the positive rotation mode as shown in Figure 5 the figure, the synchronous belt 214 is driven to rotate counterclockwise. At this time, the lengths of the distance a and the distance b are reduced equally, and the left centering assembly 21 and the right centering assembly 22 approach each other.

[0067] Correspondingly, when the driving wheel 216 rotates clockwise, the synchronous belt 214 is driven to rotate clockwise. At this time, the lengths of the distance a and the distance b are increased equally, and the left centering assembly 21 and the right centering assembly 22 are separated from each other.

[0068] During operation, the right calibration jig 211 at the front end of the right connecting plate 223 in the automatic centering and calibration device for optical lenses is used as the reference contact point. After the reference contact point is adjusted according to the lens radius size, the left calibration jig 210 at the front end of the left connecting plate 218 is pushed forward to contact the lens and then the left calibration jig 210 is fixed. The left calibration jig 210 only needs to be adjusted to a specified position once to meet the requirements of different size lenses. After the initial lens size is adjusted, the approach and separation opening distances of the centering and calibration device can be set according to different lens sizes. After setting the current size and saving it, when processing lenses of the same size later, only the parameters need to be repeatedly called in the control system.

[0069] Based on the above working principle, the device provided in this embodiment drives the driving wheel 216 to rotate through the motor 215, and at the same time, the synchronous belt 214 follows the driving wheel 216 to rotate, so as to drive the left centering assembly 21 and the right centering assembly 22 to approach or separate from each other, realizing automatic centering and calibration. The structure is simple, the accuracy is high, the repeatability of centering and centering accuracy is high, the centering clamping force is controllable, automatic control is realized, the operation is convenient, and the labor intensity of workers is reduced.
