Description

Technical Field

[0001] The utility model relates to the technical field of optical glass production positioning, in particular to an optical glass production positioning mechanism. Background Art

[0002] The optical glass production positioning mechanism is a key equipment used in the optical glass manufacturing process. Its main function is to ensure that the glass maintains precise position and direction during the production process. This positioning mechanism plays a vital role in the cutting, coating and other processes of optical glass. Optical glass is physically and chemically isotropic, so its finished components are widely used in lenses, prisms, reflectors and other fields in optical instruments. In order to ensure the high quality and precision of these components, the positioning mechanism plays a key role in the production process. In addition, the coating process of optical glass also requires the use of a positioning mechanism. The coating positioning mechanism usually includes an auxiliary mechanism, and the positioning mechanism is fixedly installed on the top of the auxiliary mechanism. During the coating process, the glass to be coated is first placed on the pad, and then the positioning mechanism is started to ensure that the glass remains stable during the coating process. This positioning mechanism not only improves the coating accuracy, but also improves production efficiency.

[0003] In the prior art, after optical glass products are cut, they need to be coated according to quality and transmittance requirements. During the coating process, existing lens products are generally placed on a support plate with a concave accommodating cavity. After the coating is completed, the coated optical glass lens in the concave accommodating cavity is difficult to remove, and it is easy to touch the surface of the lens and leave fingerprints or marks, which brings trouble to the subsequent cleaning of the lens and is also easy to cause damage to the lens surface after the coating process. At the same time, the optical glass may rotate during the coating process in the accommodating cavity, resulting in uneven thickness formed on the surface of the optical glass, affecting the quality of the coating. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide an optical glass production positioning mechanism to solve the technical problem that existing lens products are generally placed on a support plate with a concave accommodating cavity during coating. After coating, the coated optical glass lens in the concave accommodating cavity is difficult to remove, and it is easy to touch the surface of the lens and leave fingerprints or traces, which brings trouble to the subsequent cleaning work of the lens and easily causes damage to the lens surface after coating.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an optical glass production positioning mechanism, comprising a base, a first cavity is provided at the top of the base, a movable seat is slidably connected to the top of the base, a second cavity is provided at the top of the movable seat, the first cavity and the second cavity can form a accommodating cavity adapted for the optical glass, the accommodating cavity is provided with a through groove that cooperates with the movable seat, the bottom end of the base is fixedly connected to a box body, a fan is provided on one side of the box body, the output end of the fan is fixedly connected to an exhaust pipe, one end of the exhaust pipe is fixedly connected to an air cavity, the top of the air cavity is movably connected to an exhaust tube, and the bottom end of the movable seat is provided with an exhaust port that cooperates with the exhaust tube.

[0006] By adopting the above technical solution, the worm is driven to rotate by the movable seat through the rotating shaft, thereby driving the turbine to rotate, and then achieving the effect of driving the screw up and down through the threaded barrel, so that the movable seat is lowered to be flush with the fixed seat, and the first cavity on the movable seat and the second cavity on the base form a accommodating cavity. The optical glass to be coated is placed in the accommodating cavity for coating operation. After the coating is completed, the movable seat is lifted by the knob to facilitate the removal of the coated optical glass. At the same time, a fan is provided, and the negative pressure generated by the operation of the fan adsorbs the optical glass in the accommodating cavity to prevent it from rotating during coating.

[0007] Furthermore, a rotating shaft is movably connected to the bottom end of the box body, and one end of the rotating shaft extends to the outside of the box body, and one end of the rotating shaft is fixedly connected to a knob.

[0008] By adopting the above technical solution, the rotating shaft is driven to rotate by adjusting the knob, thereby achieving the effect of rotating the worm.

[0009] Furthermore, two groups of worm gears are symmetrically sleeved on the surface of the rotating shaft, and a turbine matched with the two groups of worm gears is movably connected to the bottom end of the interior of the box.

[0010] By adopting the above technical solution, the rotation of the worm drives the turbine to rotate, thereby achieving the effect of driving the lead screw to move.

[0011] Furthermore, two sets of screws are fixedly connected to the bottom end of the movable seat, and a threaded barrel matched with the screws is fixedly connected to the top end of the turbine.

[0012] By adopting the above technical solution, the threaded barrel rotates to drive the screw rod to move up and down.

[0014] By adopting the above technical solution and arranging the slider and the slide groove, the effect of guiding the screw rod to move up and down is achieved.

[0015] Furthermore, a plurality of groups of ribs are equidistantly arranged on the surface of the accommodating cavity, and the ribs are distributed in a ring shape.

[0016] By adopting the above technical solution, the provision of annularly distributed ribs increases friction, thereby achieving the effect of further fixing the optical glass.

[0017] In summary, the utility model mainly has the following beneficial effects: the utility model drives the worm to rotate through the rotating shaft through the movable seat, thereby driving the turbine to rotate, and then achieves the effect of driving the screw up and down through the threaded barrel, so that the movable seat is lowered to be flush with the fixed seat, and the first cavity on the movable seat and the second cavity on the base form a accommodating cavity. The optical glass to be coated is placed in the accommodating cavity for coating operation. After the coating is completed, the movable seat is lifted by the knob, so that the coated optical glass is conveniently taken out. At the same time, a fan is provided, and the negative pressure generated by the operation of the fan adsorbs the optical glass in the accommodating cavity to avoid its rotation during coating.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] An optical glass production positioning mechanism, such as Figure 1-5 As shown, it includes a base 1, a first cavity 2 is provided at the top of the base 1, a movable seat 7 is slidably connected to the top of the base 1, a second cavity 3 is provided at the top of the movable seat 7, the first cavity 2 and the second cavity 3 can form a accommodating cavity 4 adapted to the optical glass, the accommodating cavity 4 is provided with a through groove 6 that cooperates with the movable seat 7, the bottom end of the base 1 is fixedly connected to a box 12, a fan 18 is provided on one side of the box 12, the output end of the fan 18 is fixedly connected to an exhaust pipe 19, one end of the exhaust pipe 19 is fixedly connected to an air cavity 20, the top of the air cavity 20 is movably connected to an exhaust tube 21, and an exhaust port 22 that cooperates with the exhaust tube 21 is provided at the bottom end of the movable seat 7. Specifically, when in use, the movable seat 7 drives the worm 15 to rotate through the rotating shaft 13, and the rotation of the worm 15 further drives the turbine 16 to operate. The rotation of the turbine 16 pushes the screw 10 up and down through the threaded cylinder 17, so that the movable seat 7 can be accurately lowered to a state flush with the base 1;

[0027] At this time, the first cavity 2 on the movable seat 7 and the second cavity 3 on the base are combined to form a receiving cavity 4. The operator places the optical glass to be coated in this receiving cavity 4 to ensure its position is stable. When the optical glass is placed, the coating operation begins;

[0028] During the coating process, in order to ensure that the optical glass does not move or rotate, a fan 18 system is specially set up in the device. The fan 18 firmly adsorbs the optical glass in the accommodating chamber 4 through the negative pressure generated by its operation, effectively preventing the glass from rotating due to vibration or other factors during the coating process, thereby ensuring the uniformity and quality of the coating.

[0029] See also Figure 4 and Figure 5 The bottom end of the box body 12 is movably connected with a rotating shaft 13, and one end of the rotating shaft 13 extends to the outside of the box body 12. One end of the rotating shaft 13 is fixedly connected to a knob 14. Two sets of worm gears 15 are symmetrically sleeved on the surface of the rotating shaft 13. The bottom end of the box body 12 is movably connected with a turbine 16 that cooperates with the two sets of worm gears 15. The bottom end of the movable seat 7 is fixedly connected with two sets of screws 10. The top of the turbine 16 is fixedly connected with a threaded barrel 17 that cooperates with the screw 10. Slide blocks 8 are fixedly connected on both sides of the movable seat 7. Slide grooves 9 that cooperate with the slide blocks 8 are provided on both sides of the through slot 6. Specifically, after the coating operation is completed, the user can adjust by turning the knob 14 to restart the rotation of the worm gear 15 and the turbine 16, so that the screw 10 drives the movable seat 7 to rise to a height suitable for operation, which facilitates the smooth removal of the coated optical glass.

[0030] Through this design, the entire optical glass coating process is automated and efficient, which not only ensures the convenience of operation but also significantly improves the coating accuracy and quality of the finished product.

[0031] See also Figure 1 and Figure 2 A plurality of groups of ribs 5 are equidistantly arranged on the surface of the accommodating cavity 4, and the ribs 5 are distributed in a ring shape. Specifically, the provision of the ribs distributed in a ring shape increases friction, thereby achieving the effect of further fixing the optical glass.

[0032] The working principle of the utility model is as follows: when in use, the movable seat 7 drives the worm 15 to rotate through the rotating shaft 13, and the rotation of the worm 15 further drives the turbine 16 to operate. The rotation of the turbine 16 pushes the screw 10 up and down through the threaded barrel 17, so that the movable seat 7 can be accurately lowered to a state flush with the base 1;

[0033] At this time, the first cavity 2 on the movable seat 7 and the second cavity 3 on the base are combined to form a receiving cavity 4. The operator places the optical glass to be coated in this receiving cavity 4 to ensure its position is stable. When the optical glass is placed, the coating operation begins;

[0034] During the coating process, in order to ensure that the optical glass does not move or rotate, a fan 18 system is specially set in the device. The fan 18 generates negative pressure during operation to firmly adsorb the optical glass into the accommodating chamber 4, effectively preventing the glass from rotating due to vibration or other factors during the coating process, thereby ensuring the uniformity and quality of the coating.

[0035] After the coating operation is completed, the user can adjust the knob 14 to restart the rotation of the worm 15 and the worm gear 16, so that the screw 10 drives the movable base 7 to rise to a height suitable for operation, so as to facilitate the smooth removal of the coated optical glass;

[0036] Through this design, the entire optical glass coating process is automated and efficient, which not only ensures the convenience of operation, but also significantly improves the coating accuracy and quality of the finished product. At the same time, through the negative pressure adsorption function of the fan 18, the rotation or offset problem of the optical glass that may occur in the traditional coating process is effectively solved, ensuring the consistency of the coating and greatly improving production efficiency.
