[0034] The technical solutions of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Embodiment 1:

[0036] As shown in Figure 1 and Figure 2 , the centering and positioning device for optical lenses disclosed in the embodiments of the present utility model includes: a mounting base plate 625, a guide rail 606, a left centering assembly 660, a right centering assembly 661, and a driving assembly 662;

[0037] The mounting base plate 625 is provided with a guide rail 606. The left centering assembly 660 and the right centering assembly 661 are arranged on the guide rail 606, and the driving assembly 662 is installed between the left centering assembly 660 and the right centering assembly 661;

[0038] The driving assembly 662 drives the left centering assembly 660 and the right centering assembly 661 to move closer to or away from each other.

[0039] In this embodiment, a guide rail 606 is provided on the mounting base plate 625; left anti-collision blocks 613 and right anti-collision blocks 603 are respectively provided at both ends of the guide rail 606.

[0040] Preferably, in the driving assembly 662, there are a forward nut 612 and a reverse nut 608. The driving assembly 662 is connected to the left connecting plate 618 in the left centering assembly 660 through the forward nut 612, and is connected to the right connecting plate 602 in the right centering assembly 661 through the reverse nut 608.

[0041] Preferably, the driving assembly 662 includes a motor 609. Positive threaded lead screws 621 and reverse threaded lead screws 622 are provided at both ends of the motor 609. The positive threaded lead screw 621 is threadedly connected to the forward nut 612, and the reverse threaded lead screw 622 is threadedly connected to the reverse nut 608.

[0042] Preferably, the motor 609 is arranged on the mounting base plate 625 through the left fixing plate 611 or / and the right fixing plate 610, and is parallel to the guide rail 606.

[0043] In this embodiment, based on the forward nut 612 on the positive threaded lead screw 621 and the reverse nut 608 on the reverse threaded lead screw 622, the motor 609 is respectively connected to the guide rail 606 through the left connecting plate 618 in the left centering assembly 660 and the right connecting plate 602 in the right centering assembly 661;

[0044] When the motor 609 rotates, the motor 609 can drive the forward nut 612 and the reverse nut 608 to rotate through the positive threaded lead screw 621 and the reverse threaded lead screw 622, thereby driving the left centering assembly 660 and the right centering assembly 661 to move closer to or away from each other.

[0045] Preferably, the left centering assembly 660 includes a left calibration jig 619, and the right centering assembly 661 includes a right calibration jig 600. The shapes of the contact surfaces of the left calibration jig 619 and the right calibration jig 600 with the centering product match the shape of the centering product.

[0046] Preferably, the left centering assembly 660 includes a left connecting plate 618, and the right centering assembly 661 includes a right connecting plate 602. The positions of the mounting calibration jigs on the left connecting plate 618 or / and the right connecting plate 602 are of a limiting structure, and the limiting structure restricts the calibration jig from moving outward to the centering product.

[0047] Among them, the calibration jig includes: a left calibration jig 619 and a right calibration jig 600.

[0048] As shown Figure 2 in the figure, the limiting structure is the front end of the left connecting plate 618 in the left centering component 660, that is, 630 at the position for installing the left alignment jig 619 is used as the limiting structure.

[0049] In this embodiment, the front end of the left connecting plate 618 is the limiting structure. The limiting structure forms a forward baffle structure at the front end of the left connecting plate 618. The left alignment jig 619 is installed at the front end of the left connecting plate 618 and its right side is restricted by the baffle structure. In this way, the limiting of the left alignment jig 619 can be realized, and the left alignment jig 619 can be prevented from moving when centering the product. It should be noted that on the premise that the alignment jig is frequently replaced, the reference position point of the alignment jig takes the limiting structure that restricts the movement of the alignment jig as the limiting position 630 of the reference position. Of course, the front end of the left connecting plate 618 or / and the front end of the right connecting plate 602 can also be the limiting structure. Therefore, the limiting position 630 that restricts the movement of the alignment jig can be on the side of the left connecting plate 618, or on the side of the right connecting plate 602, or both the left connecting plate 618 and the right connecting plate 602 can be provided with the limiting position 630 at the same time. It can also be that the positions where the left connecting plate 618 or / and the right connecting plate 602 install the alignment jig are non-limiting structures, which are not restricted by this description, as long as they can meet the actual requirements and the shape of the alignment jig.

[0050] Furthermore, in this embodiment, the top shape of the left alignment jig 619 is a cut surface shape, and the top shape of the right alignment jig 600 is a double-ended V shape. Of course, if the left connecting plate 618 is a non-limiting structure, the top shape of the left alignment jig 619 can also be a double-ended V shape or a single-ended top V shape, or the top shape of the alignment jig can be changed according to the centered product to match the shape of the centered product M.

[0051] Preferably, the left centering component 660 includes a left slider 615. The left slider 615 is slidably installed on the guide rail 606, and the left slider 615, the left connecting plate 618, and the left alignment jig 619 are connected in sequence.

[0052] Preferably, the right centering component 661 includes a right slider 605. The right slider 605 is slidably installed on the guide rail 606, and the right slider 605, the right connecting plate 602, and the right alignment jig 600 are connected in sequence.

[0053] Preferably, a first origin coordinate switch 616 is provided below the left connecting plate 618.

[0054] As another example, a first origin coordinate switch 616 is provided below the right connecting plate 602.

[0055] Furthermore, in this embodiment, the left gasket 620 is disposed on the left correction jig 619, and the right gasket 601 is disposed on the right correction jig 600; as another example, the left gasket 620 and the right gasket 601 do not need to be installed on the correction jig.

[0056] The working principle of the device provided in this embodiment is as follows:

[0057] like Figure 4 As shown, distance a is the length of the reverse threaded screw 622, that is, the distance between the vertical center line and the left side line, and distance b is the length of the forward threaded screw 621, that is, the distance between the vertical center line and the right side line. The lengths of distance a and distance b are equal.

[0058] When the motor 609 rotates forward, the motor 609 drives the forward threaded screw 621 and the reverse threaded screw 622 to rotate forward. At this time, the forward nut 612 moves toward the vertical center line through the forward threaded screw 621; the reverse nut 608 moves toward the vertical center line through the reverse threaded screw 622. Obviously, the left centering assembly 660 and the right centering assembly 661 can be further driven to move closer to each other.

[0059] Correspondingly, when the motor 609 rotates in the reverse direction, the motor 609 drives the forward threaded screw 621 and the reverse threaded screw 622 to rotate in the reverse direction. At this time, the forward nut 612 moves toward the left line through the forward threaded screw 621; the reverse nut 608 moves toward the right line through the reverse threaded screw 622. Obviously, the left centering assembly 660 and the right centering assembly 661 can be further driven to separate from each other.

[0060] When working, the left correction fixture 619 at the front end of the left connecting plate 618 in the centering and positioning device is the reference contact point. After the reference contact point is adjusted according to the radius size of the lens, the right correction fixture 600 at the front end of the right connecting plate 602 is pushed forward to contact the upper lens and fix the right correction fixture 600. The right correction fixture 600 only needs to be adjusted once to the specified position to meet the requirements of lenses of different sizes. When the initial size of the lens is adjusted, the distance of the closing and separation opening size of the centering and positioning device can be set according to the size of different lenses. After setting the current size, save it. When processing lenses of the same size in the future, you only need to repeatedly call the parameters in the control system.

[0061] Based on the above working principle, the device provided in this embodiment drives the forward threaded screw 621 and the reverse threaded screw 622 to rotate by rotating the motor 609, so that the left centering component 660 and the right centering component 661 are close to or separated from each other on the same horizontal line, achieving high precision of centering and centering, high repeatability of centering and centering, controllable centering clamping force, realizing automatic control, and making the operation easier, more efficient and labor-saving.
