Description

Technical field:

[0002] The utility model relates to a glue dispensing device, in particular to a glue dispensing device applied to an optical lens. Background technology:

[0004] Optical lenses are essential components in machine vision systems, which directly affect 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 the frame are produced separately, they need to be assembled. Currently, the assembly of the lens and the frame is usually done manually by applying glue to the corresponding positions of the lens or the frame, and then assembled manually or by a robot. This assembly method not only has limited production efficiency, but also wastes manpower.

[0006] For example, the Chinese patent "An optical lens dispensing device" with announcement number CN211190784U includes: a dispensing device capable of moving in 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 device 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 structure of the dispensing device, makes the dispensing device layout more compact, and is more convenient to debug and use; however, the device is not convenient for adjusting the dispensing position, so as to meet the assembly of lenses and frames of various specifications; and it is impossible to ensure that the lens or frame is firmly installed when dispensing, which is prone to omissions or voids in the gluing position (all caused by uneven glue coating). Summary of the invention:

[0014] Preferably, a shielding plate is provided on the swing block at the back side of the UV lamp and close to the injection syringe.

[0015] The working principle of the utility model optical lens dispensing equipment:

[0016] By moving the sliding mounting seat horizontally and vertically, the position of the glue injection syringe (which is equipped with a glue injection needle) can be adjusted in the horizontal and vertical coordinates. By turning the manual wheel, the glue injection syringe and the glue injection needle can be adjusted in the vertical coordinate, that is, the three-coordinate adjustment is completed, thereby meeting the gluing needs of lenses and frames of different specifications. In addition, by loosening the stepped bolts, swinging the glue injection syringe swing plate to a suitable position, and then locking the stepped bolts, the tilt position of the glue injection syringe and the glue injection needle relative to the lens and the frame can be adjusted.

[0030] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The optical lens dispensing device of the utility model comprises a base cabinet 1 and a bottom plate 2 installed on the upper surface of the base cabinet 1. The base cabinet 1 is a rectangular cabinet body, and electric control devices and the like can be installed inside the cabinet. The upper part of the base cabinet 1 is provided with a base cabinet upper plate body 38, and the bottom plate 2 is installed on the base cabinet upper plate body 38.

[0032] A sliding mounting seat 3 capable of horizontal and vertical movement and positioning is installed on the bottom plate 2. The sliding mounting seat 3 can slide through a horizontal guide rail or a vertical guide rail. A vertical mounting seat 4 is provided on the sliding mounting seat 3. Two vertical guide rods 5 and a slider 6 slidably connected to the guide rods 5 are provided on the vertical mounting seat 4. Both sides of the slider 6 can smoothly rise and fall and slide on the guide rods 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 vertical mounting seat 8. The upper end of the screw rod 7 passes through the upper part of the vertical 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.

[0033] 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 and is located next to the bottom plate 2. 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 and is located 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).

[0034] 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 inserted into 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.

[0035] By loosening the stepped bolt, swinging the injection syringe swing plate to an appropriate position, and then locking the stepped bolt, the injection syringe and the injection needle can be adjusted in their tilted 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.

[0036] A second slide rail cylinder 21 is provided on the vertical frame 11, and the UV lamp 12 is installed on the telescopic end of the second slide rail cylinder 21.

Transverse arms 24 are installed on the four peripheral sides of the rectangular block 23, and a swing block 25 is installed at the outer end of each transverse arm 24. 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 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 to be installed.

[0038] 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 prevent the glue in the injection syringe and the needle from being irradiated by the UV lamp, thereby preventing the glue from solidifying.

[0039] The working principle of the utility model optical lens dispensing equipment:

[0040] By moving the sliding mounting seat horizontally and vertically (which is the existing horizontal and vertical sliding seat, 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 glue dispensing of lenses and frames of different specifications can be met; in addition, by loosening the stepped bolts, swinging the glue injection syringe swing plate to the appropriate position, and locking the stepped bolts, the tilt position of the glue injection syringe and the glue injection needle relative to the lens and the frame can be adjusted.

[0041] In addition, in order to make the glue applied on the lens 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 shaft mechanism with suction for an optical lens dispensing device. The mechanism is specific: a negative pressure channel 28 connected to 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 connected to 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 peripheral edge of the lens, the glue is sucked from the surface of the lens to the peripheral edge where the lens and the frame are in contact under the action of negative pressure, thereby avoiding the problem of glue dispensing voids or glue leakage in the local peripheral position where the lens and the frame are in contact, which is beneficial to ensuring the quality of glue dispensing and improving the waterproofness of the lens.

[0042] The above-mentioned lens mounting seat 13 includes a fixed seat 29 installed on the upper plate 38 of the base cabinet and a rotating seat 30 rotatably connected to the fixed seat, and the fixed seat 29 is locked on the upper plate 38 of the base cabinet by bolts; the middle part of the fixed seat 29 has a through hole, and a bearing 37 (the bearing 37 can be a ball bearing, etc.) is installed in the through hole, and the lower part of the rotating seat extends into the inner hole of the bearing.

[0043] The rotating seat 30 is provided with a bottom mold seat 31 adapted to the lens, and 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 transitionally matched).

[0044] The lower part of the rotating seat 30 is connected to the output shaft of the hollow motor 33 through a 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, so as to realize the rotation of the frame of the lens to be installed in the bottom mold seat 31, and the lens to be installed can be adsorbed in the positioning groove of the lens 27 through the negative pressure equipment.

[0045] Since a negative pressure channel connected to the lens is provided on the lens mounting seat, the frame and the 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), thus avoiding the problem of glue dispensing voids or glue leakage at the local periphery where the lens and the frame are in contact, which is beneficial to ensuring the glue dispensing quality and improving the waterproofness of the lens.

[0046] 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 plurality of connecting rods 36. The hollow motor 33 is a commercially available product and is not similarly described here. The coupling 32 differs from the existing coupling in that it has a hollow channel (i.e., a negative pressure channel) in the middle.

[0047] For a reasonable design, the lower parts of the hollow motor 33, the suspended plate 35 and the rotating seat 30 are located inside the bottom cabinet.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant 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, which should be included in the scope of the technical solution for protection of the utility model.
