Abstract
Description
Technical Field
[0001] This utility model relates to the field of vision lens connection technology, and in particular to a connection structure for machine vision lenses. Background Technology
[0002] In a machine vision system, the vision lens is equivalent to the human eye. Its main function is to focus the optical image of the target onto the photosensitive array of the image sensor (camera). All image information processed by the vision system is obtained through the lens, and the quality of the lens directly affects the overall performance of the vision system. When connecting machine vision lenses, a connection structure is used to connect and install them.
[0003] Patent document CN221103472U discloses a connection structure for a machine vision lens, including a back plate, a front plate, and a mounting frame. The back plate has a rectangular movable opening, and a guide plate is slidably connected to the inner wall of the rectangular movable opening. A mounting plate is fixedly connected to one outer wall of the guide plate. The mounting frame is fixedly mounted on the top outer wall of the mounting plate. An opening is provided on one side of the back plate, and a limit plate is slidably connected to the inner wall of the opening. This invention allows for lateral movement of the mounting plate via the rectangular movable opening and the guide plate. This movement causes the mounting plate to move laterally, which in turn moves the machine vision lens laterally, thus adjusting the position of the machine vision lens until it is directly aligned with the phone's camera. This allows for alignment of the machine vision lens with most phone cameras, making it practical and suitable for widespread promotion and use.
[0004] While the aforementioned application allows for direct lens alignment in practical applications, it makes quick connection and disassembly difficult, thus affecting the connection and positioning of the structure and reducing its ease of use. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figures 1-4 A connection structure for a machine vision lens includes a positioning plate 1, a limiting component 2 on one side of the positioning plate 1, and a tightening component 3 on the other side of the positioning plate 1.
[0030] The limiting component 2 includes a circular groove 200 formed on one side of the positioning plate 1. An annular groove 201 is formed on the inner wall of the circular groove 200. A vertical groove 202 is connected to the top of the annular groove 201. A positioning ring 203 is disposed inside the circular groove 200. A lens body 204 is fixedly installed inside the positioning ring 203. A vertical block 205 is fixedly installed on the surface of the positioning ring 203. A vertical tube 206 is fixedly installed on the top of the vertical block 205. A tension spring 207 is fixedly installed on the inner bottom wall of the vertical tube 206. A piston block 208 is fixedly installed on the top of the tension spring 207. A pressure plate 209 is rotatably connected to the top of the piston block 208 via a bearing. A [missing information - likely a component or component] is fixedly installed at the bottom of the pressure plate 209. The arc-shaped plate 210 has anti-slip textures on its lower surface, and its lower surface fits against the upper surface of the positioning plate 1. The arc-shaped plate 210 increases friction with the positioning plate 1 during use, thus preventing the positioning ring 203 from loosening. The top of the vertical tube 206 has a circular hole for the piston block 208 to pass through, and the inner wall of the hole is slidably connected to the surface of the piston block 208. The piston block 208 is adapted to the circular hole. The outer ring of the bearing is fixedly connected to the top of the piston block 208, and the inner ring of the piston block 208 is fixedly connected to the bottom of the pressure plate 209. The circular hole facilitates the passage of the piston block 208 during use. Meanwhile, the bearing arrangement facilitates the rotation of the pressure plate 209, thereby enabling convenient pressing and release of the limit operation, improving the ease of use of the structure. The width of the vertical block 205 is the same as the width of the vertical groove 202, and the inner walls of the vertical groove 202 are slidably connected to the two sides of the vertical block 205. The inner top and bottom walls of the annular groove 201 are slidably connected to the top and bottom of the vertical block 205, respectively, and the vertical groove 202 is connected to the annular groove 201. The connection between the vertical groove 202 and the annular groove 201 allows the vertical block 205 to be rotated when the vertical groove 202 is inserted, limiting the positioning ring 203 and preventing it from loosening, thus maintaining its position. To ensure the stability of the positioning ring 203, a compression tube 211 is fixedly installed at the bottom of the positioning ring 203. A compression spring 212 is fixedly installed on the inner top wall of the compression tube 211. A piston plate 213 is fixedly installed at the bottom of the compression spring 212. A compression block 214 is fixedly installed at the bottom of the piston plate 213. The bottom of the compression block 214 is slidably connected to the inner bottom wall of the circular groove 200. The limiting component 2 facilitates quick connection and disassembly of the lens body 204 during use, and facilitates the connection and positioning of the lens body 204 during use. This improves the ease of use of the structure and also facilitates subsequent disassembly and assembly operations by staff.
[0031] Reference Figure 2 In a preferred embodiment, the tightening assembly 3 includes a threaded groove on one side of the positioning plate 1 and a positioning tube 300 fixedly installed on one side of the positioning plate 1. A stud 301 is inserted into the surface of the positioning tube 300. The positioning tube 300 facilitates the fixing of the structure to the fixed component during use, thereby maintaining the stability of the structure installation and improving the connection firmness of the structure. A threaded hole for the stud 301 to pass through is opened on the surface of the positioning tube 300. The threaded hole is threadedly connected to the stud 301. A hexagonal hole is opened at one end of the stud 301. The tightening assembly 3 facilitates the installation and positioning operation of the structure during use, thereby facilitating subsequent connection and positioning operations and improving the ease of use of the structure. The stud 301 and the threaded hole facilitate the tightening operation of the stud 301 during use, thereby preventing the stud 301 from loosening during use and facilitating subsequent positioning and pressing operations.
[0032] Working principle: During use, the positioning plate 1 is clamped onto the surface of the structure and tightened so that the positioning tube 300 on the positioning plate 1 is threadedly connected to the surface of the structure. Then, the stud 301 is tightened so that one end of the stud 301 abuts against the surface of the structure. Then, the positioning ring 203 on the lens body 204 is inserted into the inside of the circular groove 200, so that the vertical block 205 is inserted into the inside of the vertical groove 202. After the vertical block 205 is inserted into place, the positioning ring 203 is rotated, so that the vertical block 205 is clamped into the annular groove 201. At the same time, the pressure plate 209 is rotated so that the arc plate 210 on the pressure plate 209 presses against one side of the positioning plate 1. At the same time, the compression spring 212 presses against the compression block 214 on the piston plate 213, thereby facilitating the compression and limiting operation of the positioning ring 203.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
