Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a mounting frame structure for an optical lens. Background Art

[0002] An optical lens is an essential component in a machine vision system, directly affecting the quality of the captured image and the implementation and effect of algorithms. Optical lenses can be classified into short-focus lenses, medium-focus lenses, and long-focus lenses according to their focal lengths; wide-angle, standard, and telephoto lenses according to their field of view sizes; and fixed-aperture fixed-focus lenses, manual-aperture fixed-focus lenses, automatic-aperture fixed-focus lenses, manual zoom lenses, automatic zoom lenses, automatic-aperture motorized zoom lenses, and motorized triple-variable (aperture, focal length, and focus are all variable) lenses according to their structures.

[0003] After retrieval, Chinese Patent Publication No.: CN 216178119 U discloses a lens clamping device for an optical lens assembly machine, which includes a mounting substrate. A first electric push rod is arranged on the mounting substrate. The bottom end of the first electric push rod is installed with a vacuum suction device through a mounting shaft. A rotatable connecting frame and a support plate are arranged outside the vacuum suction device. The support plate can prevent the optical lens from falling and being damaged during the transfer process. In addition, under the action of a second electric push rod, through the cooperation of a moving ring, a connecting rod and the connecting frame, the connecting frame is driven to rotate around the hinge axis of the connecting frame and the mounting frame. The overall structure is compact and space-saving. A buzzer and a button switch that cooperate with each other are arranged on the support plate. When the lens falls on the support plate, the button switch is pressed, causing the buzzer to generate an alarm, reminding the staff to perform corresponding processing, preventing the optical lens from falling to the ground and being damaged, and at the same time, the falling information can be fed back in time, saving production costs and improving production efficiency.

[0027] Embodiment 2

[0028] Please refer to Figures 1-4 , on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the mounting frame mechanism 3 includes a mounting frame body 31. The lower surface of the mounting frame body 31 is fixedly connected with a lens body 32, and the lower surface of the mounting frame body 31 is fixedly connected with a liquid holding vessel 33. The inner surface of the mounting frame body 31 is provided with water outlet holes 34 in a circumferential array. Through the arranged water outlet holes 34, after a cleaning liquid is arranged in the mounting frame body 31, it enters the liquid holding vessel 33 through the water outlet holes 34 and then flows into the lens body 32 through the gaps. The staff only needs to wipe to realize the function of cleaning the lens. The inner surface of the mounting frame body 31 is fixedly connected with an annular water baffle 35. Through the arrangement of the annular water baffle 35, the cleaning liquid can be separated from the observation channel and the lens body 32 to prevent the cleaning liquid from affecting the observation. The mounting frame mechanism 3 further includes a water inlet groove 36. The inner surface of the annular water baffle 35 is provided with water inlet grooves 36 in a circumferential array. Through the arranged water inlet grooves 36, it can effectively ensure that the cleaning liquid enters the liquid holding vessel 33 through the cooperation of the water inlet grooves 36 and the water outlet holes 34. The inner surface of the mounting frame body 31 is provided with a groove 37, and the inner surface of the groove 37 is slidably connected with an annular elastic gate 38. Through the arrangement of the groove 37 and the annular elastic gate 38, the annular elastic gate 38 is composed of a spring and an annular gate. The annular gate can effectively block the cleaning liquid outside the annular elastic gate 38 through the cooperation with the groove 37. At the same time, both ends of the spring are fixed to the annular gate and the mounting frame body 31. Through the elasticity of the spring, the annular gate is stably clamped in the groove 37, thereby realizing effective waterproofing for the lens body 32. The outer arc surface of the mounting frame body 31 penetrates through a movable plate 4 and is slidably connected with the movable plate 4. The movable plate 4 is hinged to one end of a bracket 5, and the annular elastic gate 38 is hinged to the other end of the bracket 5. The upper surface of the mounting frame body 31 is provided with an observation hole 6, which is convenient for the staff to observe. The observation hole 6 and the lens body 32 are on the same horizontal plane.

[0029] In this embodiment, through the installation frame body 31, the annular water baffle 35, the bracket 5, the water inlet tank 36 and the liquid holding vessel 33 provided, the cleaning liquid is isolated between the installation frame body 31 and the annular elastic gate 38 by the annular water baffle 35 and the annular elastic gate 38. When cleaning the lens, only need to press the movable plate 4 to move towards the inside of the installation frame body 31, lift the annular elastic gate 38 through the bracket 5. After the cleaning liquid enters the liquid holding vessel 33 through the water outlet hole 34 and the water inlet tank 36, the cleaning liquid slides out through the gap between the liquid holding vessel 33 and the lens body 32 and contacts the lens body 32. The staff only needs to wipe the lens.

[0030] Working principle: When using the lens body 32, after pulling out the elastic latch 28 from the card slot 27, move the annular block 21 up and down. The annular block 21 drives the installation frame body 31 to move up and down through the fixed plate 24 and the clamping plate 26 that clamps the installation frame body 31. Then, reinsert the elastic latch 28 into the card slot 27. At the same time, after reinserting the elastic latch 28 into the card slot 27, rotate the slip ring 23. The slip ring 23 drives the elastic tapered rod 29 to rotate. After the inclined surface of the elastic tapered rod 29 is squeezed by the round hole 210, it will move upward and compress the spring at the same time. After the installation frame body 31 stops rotating, the elastic tapered rod 29 rebounds into the round hole 210 through the elastic force of the spring, and limits the installation frame body 31 and the slip ring 23 at the same time. Then the staff can observe through the lens body 32.

[0031] When the lens body 32 needs to be cleaned after long-term use, press the movable plate 4 to move towards the inside of the installation frame body 31, drive the annular elastic gate 38 to move upward through the bracket 5. After disengaging from the groove 37, the cleaning liquid enters the liquid holding vessel 33 through the water inlet tank 36 and the water outlet hole 34, and slides into the bottom of the lens body 32 through the gap between the liquid holding vessel 33 and the lens body 32 to clean the lens. The staff only needs to wipe the lens body 32.
