Description

Technical Field

[0001] This utility model relates to the field of photographic detection technology, specifically to a photographic device for foreign matter inside a plastic bottle. Background Technology

[0002] In the quality inspection process of industrial production, photographic inspection is often used to replace human eyes for quality inspection. Photographic inspection is then combined with computer software and algorithms for image processing, analysis and measurement, thereby enabling automatic, high-speed and high-precision inspection of product dimensions, defects, appearance, assembly and patterns, thus ensuring industrial production efficiency.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: the existing photographic detection equipment cannot freely adjust the photographing angle of the object to be tested and the illumination angle of the light source. Utility Model Content

[0004] The purpose of this invention is to provide a device for photographing foreign objects inside a liquid bottle, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for photographing foreign objects inside a plastic bottle, comprising a base, a camera adjustment base on one side of the top of the base, a camera adjustment bracket fixedly connected to the top of the camera adjustment base, a slide rail slidably connected to the inner wall of the camera adjustment bracket, a servo-driven robot at one end of the slide rail, a movable base slidably connected to the outer wall of the slide rail, the servo-driven robot being electrically connected to the movable base, an industrial camera mounted on the top of the movable base, a manual adjustment mechanism on the top of the base opposite to the camera adjustment base, a rotary moving stage mechanism threadedly connected to the outer wall of the manual adjustment mechanism, a linear light source threadedly connected to the top of the rotary moving stage mechanism, and a background plate on one side of the manual adjustment mechanism;

[0006] The camera adjustment bracket includes a column, and a horizontal plate is movably connected to the outer wall of the opposite side of the column. An arc-shaped sliding groove is provided through the side of the horizontal plate near the column, and a vertical sliding groove is provided through the side of the horizontal plate away from the column. Bolts are fitted on the inner walls of the arc-shaped sliding groove and the vertical sliding groove.

[0007] The rotary moving platform mechanism includes a rotating shaft, the bottom of which is rotatably connected to the top of a manual adjustment mechanism. A worm gear is fixedly connected to the outer wall of the rotating shaft, and a worm is meshed with the outer wall of the worm gear. A light source mounting plate is fixedly connected to the top of the rotating shaft. One end of the worm passes through one side of a support column and is rotatably connected to a servo motor. Several threaded holes are distributed in a ring on the top of the light source mounting plate.

[0008] The beneficial effects of this utility model are as follows: the combination of column, horizontal plate, arc-shaped slide and vertical slide can realize the adjustment of the shooting angle of industrial camera; the combination of rotating shaft, worm gear, worm, light source mounting plate, servo motor and threaded hole can adjust the incident angle of line light source; and the combined adjustment of camera and light source can improve the shooting detection effect.

[0009] To ensure sufficient illumination of the object under test and to guarantee good imaging:

[0010] The setting is further configured such that a linear light source is threadedly connected to the inner wall of the threaded hole, and multiple linear light sources are symmetrically distributed about the background plate.

[0011] By adopting the above technical solution, with the structure of symmetrical distribution of the online light source and the background plate, the object under test can be fully illuminated and the imaging effect can be guaranteed.

[0012] To achieve adjustable shooting angles for industrial cameras:

[0013] The cross plate is further configured such that its angle can be adjusted along the arc-shaped slide groove and fixed by bolts, and the slide can move up and down along the vertical slide groove and its position can be fixed by bolts.

[0014] By adopting the above technical solution, the distance between the industrial camera and the background board can be adjusted, and the camera shooting angle can be adjusted.

[0015] To ensure the imaging effect:

[0016] The configuration is further defined as follows: the industrial camera is aligned with the horizontal center line of the background panel, and the center points of the industrial camera and the background panel are at the same height.

[0017] By adopting the above technical solution, the camera's image can fall on the center of the background board to facilitate the confirmation of whether there are foreign objects.

[0018] To achieve adjustable spacing between the light source and the camera:

[0019] The manual adjustment mechanism is further configured as follows: a T-shaped seat is provided, and a third slide groove is provided on the top of the T-shaped seat. A first lead screw is rotatably connected to the inner wall of the opposite side of the third slide groove. A first throttle is fixedly connected to the first lead screw outside the T-shaped seat. A T-shaped slider is threadedly connected to the outer wall of the first lead screw. A light source adjustment seat is provided on the top of the T-shaped slider. A fourth slide groove is provided on the top of the light source adjustment seat. A second lead screw is rotatably connected to the inner wall of the opposite side of the fourth slide groove. A second throttle is fixedly connected to the second lead screw outside the light source adjustment seat. The first lead screw and the second lead screw are arranged in a cross shape.

[0020] By adopting the above technical solution, the distance between the light source and the camera can be adjusted.
