Description

Technical Field

[0001] The utility model relates to the technical field of lens assembly, in particular to a lens assembly head with an adjustment structure. Background Art

[0002] Vehicle-mounted LiDAR is a mobile three-dimensional laser scanning system that describes the surface morphology of the measured object by emitting lasers and receiving return information. The reflector is an important component of the vehicle-mounted LiDAR and has a key impact on its function. During the assembly process, the assembly accuracy of the reflector needs to be ensured. By combining multiple lenses, more complex beam manipulation can be performed, such as correcting aberrations, controlling focal length, and adjusting beam shape.

[0003] Existing lens assembly usually adopts the form of gluing, which sticks two sets of lenses together with glue. It can provide a firm and precise connection. The gluing technology can not only ensure the close connection between the lenses, reduce the displacement and misalignment in the optical system, but also avoid the stress concentration and lens damage caused by mechanical fixation.

[0004] However, during the lens bonding process, if there is dust between the lenses, it will not only reduce the bonding effect, but also affect the imaging quality of the lenses. These tiny dust particles may cause light scattering and reflection problems in the optical system, thereby reducing the clarity and accuracy of the image. In addition, dust will hinder the uniform distribution of glue, resulting in insufficient bonding strength, which in turn affects the stability and durability of the optical components. In view of this, we propose a lens assembly head with an adjustment structure. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a lens assembly head with an adjustment structure, comprising an operating table 1, a motor 2 is fixedly connected to the top end surface of the operating table 1, a rotating shaft 3 is fixedly connected to the output end of the motor 2, a connecting rod 4 is fixedly connected to the side wall of the rotating shaft 3, an electric push rod 5 is fixedly connected to the end of the connecting rod 4 away from the rotating shaft 3, a suction head 6 is fixedly connected to the bottom end surface of the electric push rod 5, a connecting rod 2 7 is fixedly connected to the side wall of the rotating shaft 3, and the connecting rod 4 and the connecting rod 2 7 are 90 degrees apart. The end of the connecting rod 2 7 away from the rotating shaft 3 is fixedly connected to the electric push rod 2 8, and the bottom end face of the electric push rod 2 8 is fixedly connected to the glue head 9. The top end face of the operating table 1 is provided with an adjustment component, and the adjustment component includes a vertical rod 11, a connecting rod 12, a bracket 13, a limit block 14, a bracket 15, a cross bar 16, a mounting rod 17, a rotating rod 18, a connecting plate 19, a cleaning roller 20, a side plate 21, a spring 22, a bracket 23, an extension frame 24, a cleaning frame 25, a rubber sheet 26, and a convex strip 27.

[0026] In one embodiment of the utility model, a vertical rod 11 is fixedly connected to the top end face of the operating table 1, and a connecting rod 12 is rotatably connected to the side wall of the vertical rod 11. The end of the connecting rod 12 away from the vertical rod 11 is fixedly connected to a bracket 13. The number of brackets 13 is arranged in several groups, and the diameters of the brackets 13 in several groups are different. The axes of the brackets 13 in several groups coincide with each other. By rotating the brackets 13 with different diameters under the light source 10, the assembly device can be adapted to different assembly requirements. A light source 10 is fixedly connected to the top end face of the operating table 1, and the axis of the light source 10 coincides with the axis of the bracket 13. The lens on the bracket 13 is illuminated by the light source 10 to facilitate observation of the glue filling effect.

[0027] The top end surface of the operating platform 1 is fixedly connected to a limit block 14 , the side wall of the limit block 14 is slidably connected to a bracket 15 , and the top end surface of the bracket 15 is fixedly connected to a cross bar 16 .

[0028] The side wall of the glue dripping head 9 is fixedly connected with a mounting rod 17, and the mounting rod 17 is fixedly connected to a rotating rod 18. The side wall of the rotating rod 18 is rotatably connected with a connecting plate 19, and one end of the connecting plate 19 away from the rotating rod 18 is rotatably connected to a cleaning roller 20. The side wall of the connecting plate 19 is fixedly connected with a side plate 21, and the side plate 21 is fixedly connected to a spring 22. The side of the spring 22 away from the side plate 21 is fixedly connected to the bottom end face of the mounting rod 17.

[0029] The top end surface of the operating table 1 is fixedly connected with a bracket 23, the side wall of the bracket 23 is fixedly connected with an extension frame 24, the top end surface of the extension frame 24 is fixedly connected with a cleaning frame 25, the cleaning frame 25 is made of metal, and the cleaning frame 25 is arranged in a stepped shape. The cleaning roller 20 shakes on the cleaning frame 25 to further shake off the dust on the cleaning roller 20, and the top end surface of the extension frame 24 is fixedly connected with a rubber sheet 26, and the top end surface of the rubber sheet 26 is fixedly connected with a convex strip 27, the number of the convex strips 27 is set in several groups, and several groups of convex strips 27 are arranged at equal intervals on the top end surface of the rubber sheet 26.

[0030] The suction head 6 sucks up the lens, and then the shaft 3 rotates to the top of the bracket 13. The electric push rod 5 pushes the suction head 6 to place the lens on the bracket 13. By rotating the brackets 13 of different diameters under the light source 10, the assembly device can be adapted to different assembly requirements.

[0031] The motor 2 drives the rotating shaft 3 to rotate, so that the glue dropping head 9 is located above the lens, and then the electric push rod 28 pushes the glue dropping head 9 to move downward, and the cleaning roller 20 first contacts the top of the cross bar 16, and then the cleaning roller 20 moves along the cross bar 16. The cleaning roller 20 is made of suede and has a positive charge, while dust usually carries a negative charge or is neutral, thereby adsorbing the dust on the surface of the lens, and then the glue dropping head 9 arrives above the lens and drips glue onto the lens. By adjusting the height of the bracket 15, the cross bar 16 is located above the lens, and then the bracket 15 is fixed by bolts. The cross bar 16 is located above the lens, so that the lens and the cleaning roller 20 are not in contact, preventing the glue dropping head 9 from being stuck with glue when the cleaning roller 20 moves up, and the dust removal method is electrostatic adsorption, so it will not affect the dust removal of the lens.

[0032] The motor 2 drives the rotating shaft 3 to rotate in the opposite direction, so that the glue dropping head 9 moves to the position of the bracket 2 23. At this time, the second lens can be placed on the first lens by operating the electric push rod 1 5 and the suction head 6. At the same time, the electric push rod 2 8 pushes the glue dropping head 9 to move downward, so that the cleaning roller 20 rolls over the cleaning frame 25. Since the cleaning frame 25 is made of metal, the electrostatic charge on the cleaning roller 20 is transferred, and the dust is removed. At the same time, the cleaning frame 25 is arranged in a stepped shape, and the cleaning roller 20 shakes on the cleaning frame 25 to further shake off the dust on the cleaning roller 20, thereby improving the dust removal effect of the cleaning roller 20. Then the cleaning roller 20 moves to the rubber sheet 26. Since rubber has a high friction coefficient, the rubber sheet 26 rubs against the cleaning roller 20, so that the cleaning roller 20 carries the positive charge again.

[0033] Furthermore, a convex strip 27 is fixedly connected to the top end surface of the rubber sheet 26. The number of convex strips 27 is set in several groups. Several groups of convex strips 27 are arranged at equal intervals on the top end surface of the rubber sheet 26. The convex strips 27 increase the contact area between the rubber sheet 26 and the cleaning roller 20, thereby increasing the friction. When the cleaning roller 20 moves onto the rubber sheet 26, the friction between the convex strips 27 and the cleaning roller 20 will cause the cleaning roller 20 to carry positive charge again, which helps to better absorb and remove dust during the cleaning process.

[0034] In the utility model, when in use, the suction head 6 sucks up the lens, the electric push rod 15 pushes the suction head 6, and the lens is placed on the bracket 13. The motor 2 drives the rotating shaft 3 to rotate, so that the glue head 9 is located above the lens, and the glue head 9 moves downward. The cleaning roller 20 moves along the cross bar 16 to absorb the dust on the surface of the lens. The glue head 9 arrives above the lens and drips glue onto the lens. The motor 2 drives the rotating shaft 3 to rotate in the opposite direction, and the glue head 9 moves to the position of the bracket 23. The electric push rod 15 and the suction head 6 can be operated to place the second lens on the first lens. The electric push rod 28 pushes the glue head 9 to move downward, so that the cleaning roller 20 rolls over the cleaning frame 25 to clean the cleaning roller 20, and then the rubber sheet 26 recharges the cleaning roller 20. Further, the convex strip 27 further increases the friction of the rubber sheet 26, so that the cleaning roller 20 carries the positive charge again.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
