Description

Technical Field

[0001] The utility model relates to the field of machine vision accessories, in particular to an anti-crack machine vision lens mounting device. Background Art

[0002] The use of lenses and mirrors in machine vision systems stems primarily from their crucial role in the imaging process. Lenses are the "eyes" of a machine vision system, their primary function being to focus the optical image of the target object onto the photosensitive surface of an image sensor (such as a CCD or CMOS), thereby enabling high-quality image capture. Lens quality directly impacts the overall performance of the vision system, including image clarity, resolution, contrast, and depth of field. As part of the lens, mirrors are responsible for refracting and focusing light, thereby ensuring image quality.

[0003] In order to prevent damage to the lens due to hard contact, basic lens mounting devices generally use rubber or sponge buffers to contact the lens surface. However, due to the different heights at both ends and the center of the lens, the buffers often undergo significant deformation. When the over-compressed buffer contacts the lens, the cushioning performance is limited, and the anti-breakage protection performance is general, which has certain limitations.

[0004] In summary, a crack-proof machine vision lens mounting device is proposed to solve the above problems. Utility Model Content

[0038] It also includes an adsorption stabilization component 300, which is installed on the carrier frame 101a. The adsorption stabilization component 300 includes an electric push rod 301, and the output end of the electric push rod 301 is fixedly connected to the horizontal plate 301a.

[0046] The left and right sides of the double-headed screw 201 are smooth and movably connected to the base 101 through bearings. This design can effectively ensure the rotational stability of the double-headed screw 201. A handwheel is fixedly connected to the right end of the double-headed screw 201 and located on the right side of the base 101 to facilitate the staff to drive the double-headed screw 201 to rotate.

[0048] By providing the placement plate 101b, the lens can be placed and carried, and can be pushed in and out flexibly. By providing the slide groove 101c, the displacement of the displacement plate 201a can be guided to ensure the stability of the displacement plate 201a. By providing the storage groove 101d, the installation space requirements of the double-headed screw 201 and the displacement space requirements of the displacement plate 201a can be met. By providing the T-slot 201a-1 and the T-block 202a, the positioning seat 202 can be installed quickly and accurately. By providing the hollow sleeve 301a-1 and the short tube 301a-1c, the incoming gas can be diverted and transmitted to multiple sleeves 301 In a-1a, by providing an air pressure sensor 301a-1a1, the air pressure in the sleeve 301a-1a can be detected in real time. By providing an auxiliary suction cup 301a-1a3, it can contact the side of the lens to achieve the function of auxiliary adsorption. By providing the sleeve 301a-1a and the sliding rod 301a-1a2, the auxiliary suction cup 301a-1a3 can be flexibly moved up and down. By providing a vacuum generator 301a-2 and a vacuum suction cup 301a-2a, when the vacuum generator 301a-2 is in the working state, the vacuum suction cup 301a-2a can contact the top of the lens to perform vacuum adsorption.

[0049] In actual application, the device is equipped with a controller, and the electric push rod 301, vacuum generator 301a-2, air pump 301a-3, air pressure sensor 301a-1a1, and solenoid valve 301a-1b are all electrically connected to the controller;

[0050] In actual application, a mounting block is fixedly connected to the left side of the horizontal plate 301a, and the air pump 301a-3 is fixed to the mounting block by bolts.

[0051] During use, all components are in the initial installation state. First, according to the specifications of the lens, a suitable positioning seat 202 is selected, and with the cooperation of the T-block 202a and the T-slot 201a-1, the positioning seat 202 is stably and quickly installed on the displacement plate 201a. Then the lens is placed at the top center of the placement plate 101b, and the placement plate 101b is pushed into the base 101 so that the lens is located at the bottom of the vacuum suction cup 301a-2a and the auxiliary suction cup 301a-1a3. At this time, the electric push rod 301 is controlled to extend and work, so that the horizontal plate 301a gradually moves downward, and the vacuum suction cup 301a-2a first contacts the lens. Then the vacuum generator 301a-2 is controlled to work and cooperate with the vacuum suction cup 301a-2a to complete the vacuum adsorption of the lens. Then, the detection pressure value of the air pressure sensor 301a-1a1 is set to control the air pump 301a-3 to work and the solenoid valve 301a-3 to work. 01a-1b is opened, so that the gas is transmitted through the hollow sleeve 301a-1 and the short tube 301a-1c and enters the multiple sleeves 301a-1a. The air pressure gradually increases, and the sliding rod 301a-1a2 gradually moves downward until the bottom of the auxiliary suction cup 301a-1a3 contacts and adsorbs the lens. As the gas continues to flow in, the auxiliary suction cup 301a-1a3 cannot move further downward, so the air pressure in the sleeve 301a-1a gradually increases, and the auxiliary suction cup 301a-1a3 fits more and more tightly with the lens. When the corresponding air pressure sensor 301a-1a1 detects that the air pressure reaches the preset value, the signal is transmitted to the controller, and the controller automatically controls the corresponding solenoid valve 301a-1b to close to avoid damage and breakage of the lens due to overpressure, until the multiple auxiliary suction cups 301a-1a3 complete the multi-position adsorption of the lens to ensure the stability of the lens installation.

[0052] In summary, by setting the placement plate 101b, the storage groove 101d, the displacement clamping assembly 200 and the adsorption stabilization assembly 300, it has the advantage of stable adsorption, can control the electric push rod 301 to extend to work, and the vacuum generator 301a-2 cooperates with the vacuum suction cup 301a-2a to perform vacuum adsorption on the center of the lens, and then controls the air pump 301a-3 to work and let the gas in, so that the auxiliary suction cup 301a-1a3 gradually moves down and adsorbs the side of the lens, ensuring the stability of the lens positioning and installation, and can effectively prevent the lens from breaking.
