Description

Technical field:

[0002] The utility model relates to a rotating mechanism with suction force of optical lens dispensing equipment. Background technology:

[0004] Optical lenses are essential components in machine vision systems, directly affecting the quality of imaging and the implementation and effectiveness of algorithms.

[0005] An optical lens includes a lens and a frame for mounting the lens. After the lens and frame are produced separately, they need to be assembled. Currently, the assembly of the lens and frame is usually done by manually applying glue to the corresponding positions of the lens or frame, and then assembled manually or by a robot. This assembly method not only has limited production efficiency but also wastes manpower. At the same time, the gluing of the lens or frame is prone to problems such as glue leaks or voids.

[0006] For example, the Chinese patent "An Optical Lens Dispensing Equipment" with announcement number CN211190784U includes: a dispensing device capable of moving in the horizontal and vertical directions; a workpiece fixture, wherein the workpiece fixture is provided with a rotating device, and the rotating device is used to rotate the workpiece positioned and mounted on the workpiece fixture around a preset axis to cooperate with the dispensing device to achieve annular path dispensing of the workpiece. Although the dispensing head of this dispensing equipment does not need to be moved during the dispensing process, the annular dispensing can be completed by rotating the workpiece around its axis, which simplifies the dispensing equipment structure, makes the dispensing equipment layout more compact, and is more convenient to debug and use; however, the equipment cannot ensure that the lens or frame is firmly installed when dispensing, and is prone to problems such as omissions or voids in the gluing position (both caused by uneven glue coating). Summary of the invention:

[0008] In view of the above-mentioned problems, the purpose of the present utility model is to propose a rotating mechanism with suction for an optical lens dispensing device. The rotating mechanism with suction for the optical lens dispensing device is reasonably designed, which is conducive to avoiding the problem of uneven glue coating, ensuring the quality of glue dispensing and improving the waterproofness of the lens.

[0009] The utility model is implemented by the following scheme:

[0010] The utility model provides a rotation mechanism with suction for optical lens dispensing equipment, which is characterized by comprising a bottom cabinet and a bottom plate mounted on the upper surface of the bottom cabinet, a sliding mounting seat which can move and position horizontally and vertically is mounted on the bottom plate, a vertical frame is mounted on the upper surface of the bottom cabinet and located beside the bottom plate, a plurality of UV lamps are mounted on the vertical frame, a rotatable lens mounting seat is provided on the upper surface of the bottom cabinet and located directly below the UV lamp; a negative pressure channel is provided on the lens mounting seat, so that the frame and lens mounted on the lens mounting seat are in a negative pressure suction state.

[0011] Preferably, the above-mentioned lens mounting seat includes a fixed seat installed on the upper plate of the base cabinet and a rotating seat rotatably connected to the fixed seat, the rotating seat is provided with a bottom mold seat adapted to the lens, the lower part of the rotating seat is connected to the output shaft of the hollow motor through a coupling, the negative pressure channel is provided in the hollow motor, the coupling, the rotating seat and the bottom mold seat, the lower end of the hollow motor is connected to the air connector, and the air connector is connected to the negative pressure equipment.

[0012] Preferably, the hollow motor is fixed on a suspended plate, and the suspended plate is fixedly connected to the upper plate of the bottom cabinet through a plurality of connecting rods.

[0013] Preferably, the lower parts of the hollow motor, suspended plate and rotating seat are located inside the bottom cabinet.

[0014] Preferably, the middle portion of the fixed seat has a through hole, a bearing is installed in the through hole, and the lower portion of the rotating seat extends into the inner hole of the bearing.

[0015] Since a negative pressure channel communicating with the lens is provided on the lens mounting seat, the frame and lens mounted on the lens mounting seat are in a negative pressure suction state. When the glue injection needle squeezes out glue on the surface of the lens periphery, the glue is sucked from the surface of the lens to the periphery where the lens and the frame contact under the action of negative pressure, thereby avoiding the problem of glue spotting voids or glue leakage at the local position of the periphery where the lens and the frame contact, which is conducive to ensuring the glue spotting quality and improving the waterproofness of the lens.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The optical lens dispensing equipment of the present invention includes a base cabinet 1 and a base plate 2 installed on the upper surface of the base cabinet 1. The base cabinet 1 is a rectangular cabinet body, and electric control components and the like can be installed inside it. The upper part of the base cabinet 1 has a base cabinet upper plate body 38, and the base plate 2 is installed on the base cabinet upper plate body 38.

[0025] A sliding mounting seat 3 that can move and position horizontally and vertically and is installed on the base plate 2. The sliding mounting seat 3 can slide through a horizontal guide rail or a longitudinal guide rail. An upright mounting seat 4 is provided on the sliding mounting seat 3. Two upright guide rods 5 and a slider 6 slidably connected to the guide rod 5 are provided on the upright mounting seat 4. Both sides of the slider 6 can be smoothly lifted and lowered on the guide rod 5. A screw rod 7 is threadedly connected to the middle part of the slider 6. The two ends of the screw rod 7 are rotatably hinged on the upright mounting seat 8. The upper end of the screw rod 7 passes through the upper part of the upright mounting seat 8 and is connected to a manual turntable 9. The screw rod 7 can drive the slider 6 to rise and fall by rotating the manual turntable 9.

[0026] A glue injection syringe 10 and an injection needle installed on the glue injection syringe 10 are installed on the slider 6; a vertical frame 11 is installed on the upper surface of the base cabinet 1, next to the bottom plate 2, and a plurality of UV lamps 12 are installed on the vertical frame 11. The irradiation light of each UV lamp is located on the periphery of the lens to be installed. A rotatable lens mounting seat 13 is provided on the upper surface of the base cabinet 1, directly below the UV lamp. The lens mounting seat 13 is used to install a positioning lens (that is, a frame without a lens installed).

[0027] A bent connecting block 14 is installed on the slider 6, one end of the bent connecting block 14 is fixedly connected to the slider 6, and the other end of the bent connecting block 14 is fixedly connected to the injection syringe mounting plate 15. The front side of the injection syringe mounting plate 15 is rotatably connected to the injection syringe swing plate 16, and an arc groove 17 is provided on the injection syringe mounting plate 15. A stepped bolt 18 is passed through the arc groove, and the end thread of the stepped bolt 18 is connected to the threaded hole on the injection syringe swing plate. The end face of the stepped bolt abuts against the back side of the injection syringe mounting plate, and there is space on the bent connecting block to avoid the stepped bolt. A first slide rail cylinder 20 is installed on the injection syringe swing plate 16, and the injection syringe 10 is fixedly mounted on the first slide rail cylinder 20.

[0028] By loosening the stepped bolt, swinging the injection syringe swing plate to the appropriate position, and then locking the stepped bolt, the injection syringe and the injection needle can be adjusted to the tilt position relative to the lens and the frame. During operation, the first slide rail cylinder 20 extends, so that the free end of the injection needle can be close to the lens dispensing position.

[0029] A second slide cylinder 21 is provided on the vertical frame 11, and the UV lamp 12 is installed on the telescopic end of the second slide cylinder 21. When the second slide cylinder 21 is extended, the UV lamp 12 is driven to descend close to the position of the frame and the lens.

[0030] The telescopic end of the second slide rail cylinder 21 is equipped with a connecting rod 22, and the lower end of the connecting rod is equipped with a rectangular block 23. The four peripheral sides of the rectangular block 23 are equipped with transverse arms 24, and the outer end of each transverse arm 24 is equipped with a swing block 25. The UV lamp 12 is installed on the swing block. When the telescopic end of the second slide rail cylinder is extended to the lowermost end, the irradiation light of each UV lamp is located on the peripheral side of the lens of the lens to be installed. When it is necessary to adjust the angle of the UV lamp irradiation light, the rotation angle of the swing block 25 relative to the transverse arm 24 can be adjusted to adjust the position of the UV lamp irradiation light and the lens of the lens to be installed.

[0031] In order to prevent the light from the UV lamp from affecting the hardened glue in the injection syringe, a shielding plate 26 is provided on the swing block 25 on the back side of the UV lamp and close to the injection syringe. The shielding plate 26 can shield the glue in the injection syringe and the needle from the UV lamp, thereby preventing the glue from solidifying.

[0032] Working principle of optical lens dispensing equipment:

[0033] By moving the sliding mount horizontally and vertically (which is the existing horizontal and vertical slide, which is the existing technology and the specific structure is not described here), the position of the glue injection syringe (the glue injection syringe is equipped with a glue injection needle) in the horizontal and vertical coordinates can be adjusted, and the glue injection syringe and the glue injection needle can be adjusted in the vertical coordinate by rotating the manual wheel, that is, the three-coordinate adjustment is completed, so that the dispensing of lenses and frames of different specifications can be met; in addition, by loosening the stepped bolt, swinging the glue injection syringe swing plate to the appropriate position, and locking the stepped bolt, the tilt position of the glue injection syringe and the glue injection needle relative to the lens and frame can be adjusted.

[0034] In addition, in order to ensure that the glue applied on the lens is evenly distributed and avoid the problem of missing glue (the problem of uneven glue application on the local part of the lens and the frame), the present application also provides a rotating mechanism with suction. Specifically, a negative pressure channel 28 communicating with the lens 27 is provided on the lens mounting seat 13, so that the frame and the lens installed on the lens mounting seat are in a negative pressure suction state. Since a negative pressure channel communicating with the lens is provided on the lens mounting seat, the frame and the lens installed on the lens mounting seat are in a negative pressure suction state. When the glue injection needle squeezes out the glue on the surface of the lens periphery, the glue is sucked from the surface of the lens to the periphery where the lens and the frame are in contact under the action of negative pressure, avoiding the problem of glue application voids or glue leakage in the local periphery where the lens and the frame are in contact, which is beneficial to ensuring the glue application quality and improving the waterproofness of the lens.

[0035] The lens mounting seat 13 includes a fixed seat 29 mounted on the upper plate 38 of the base cabinet and a rotating seat 30 rotatably connected to the fixed seat. The fixed seat 29 is fastened to the upper plate 38 of the base cabinet by bolts. The middle of the fixed seat 29 has a through hole, in which a bearing 37 (the bearing 37 can be a ball bearing, etc.) is installed. The lower part of the rotating seat extends into the inner hole of the bearing.

[0036] The rotating seat 30 is provided with a bottom mold seat 31 adapted to the lens. The lens 27 (also called a lens frame) to be processed is placed in a sink groove on the upper part of the bottom mold seat 31 (the lens 27 and the sink groove can be a transition fit).

[0037] The lower part of the rotating seat 30 is connected to the output shaft of the hollow motor 33 through the coupling 32. The negative pressure channel 28 is provided in the hollow motor 33, the coupling 32, the rotating seat 30 and the bottom mold seat 31. The lower end of the hollow motor is connected to the air connector 34, and the air connector 34 is connected to the negative pressure equipment. When working, the output shaft of the hollow motor 33 drives the rotating seat 30 to rotate through the coupling 32, thereby realizing the rotation of the frame to be installed with the lens in the bottom mold seat 31, and the negative pressure equipment allows the lens to be installed to be adsorbed in the positioning groove of the lens 27.

[0038] Since a negative pressure channel communicating with the lens is provided on the lens mounting seat, the frame and lens mounted on the lens mounting seat are in a negative pressure suction state. When the glue injection needle squeezes out glue on the surface of the lens periphery, the glue is sucked from the surface of the lens to the periphery where the lens and the frame are in contact under the action of negative pressure (when there is no negative pressure, the glue will only remain on the surface of the lens periphery and will not enter the periphery where the lens and the frame are in contact). This avoids the problem of glue dispensing voids or glue leakage at the local periphery where the lens and the frame are in contact, which is conducive to ensuring the glue dispensing quality and improving the waterproofness of the lens.

[0039] In order to realize the installation of the hollow motor 33, the coupling 32, etc., the above-mentioned hollow motor is fixed on the suspended plate 35, and the suspended plate is fixedly connected to the upper plate of the base cabinet through a number of connecting rods 36. The hollow motor 33 is a commercially available product and is not compared here. The difference between the coupling 32 and the existing coupling is that it has a hollow channel (i.e., a negative pressure channel) in the middle.

[0040] For a reasonable design, the lower parts of the hollow motor 33, the suspended plate 35 and the rotating base 30 are located inside the bottom cabinet.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
