Technical Field

[0001] The utility model relates to the technical field of vision detection, in particular to an image acquisition mechanism for vision detection. Background Technique

[0002] Vision image detection is to use a machine to replace the human eye for measurement and observation. The signal is converted through a vision camera and displayed on a display. Precise detection is carried out according to other results through a high-precision camera, and the shape, image, and size parameters are detected to meet the standard. Compared with manual work, the working efficiency of the machine is higher and more standard to judge whether the processed workpiece meets the processing standard. Therefore, more and more people on the market use machines for vision detection.

[0003] The positions of the image acquisition mechanisms of existing vision image detection machines are fixed, and their image acquisition ranges are limited. They can only detect objects of limited size. When the detected object is too large, it is often necessary for the staff to manually move the detected object to ensure that the image of the detected object is completely acquired, which is inconvenient to use. For this reason, an image acquisition mechanism for vision detection is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an image acquisition mechanism for vision detection to solve the problems raised in the above background technique.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides a technical solution: As Figures 1 to 4 shown, in this embodiment, an image acquisition mechanism for vision detection includes a detection table 1. Four support columns 2 are fixedly connected to the bottom of the detection table 1. The four support columns 2 are distributed at the four corner positions of the bottom of the detection table 1. A reinforcing rod is fixedly connected between two adjacent support columns 2. A drawer plate 6 is arranged below the detection table 1. A control keyboard 3 is placed above the drawer plate 6. A display screen 7 is arranged on one side of the detection table 1 away from the control keyboard 3. The display screen 7 is fixedly connected to the side wall of the detection table 1 through a fixing plate. Fixed guide rails 4 are fixedly connected to both sides of the upper end of the detection table 1. A movable guide rail 5 is arranged above the two fixed guide rails 4. The movable guide rail 5 is connected to the fixed guide rail 4 through a sliding component. A mounting plate 9 is arranged at the side end of the movable guide rail 5. The mounting plate 9 is connected to the movable guide rail 5 through an adjusting component. An acquisition camera 8 is arranged at the side end of the mounting plate 9. The acquisition camera 8 is connected to the mounting plate 9 through a lifting component.

[0022] Among them, the sliding component includes a movable block 18. Movable blocks 18 are respectively fixedly connected to both sides of the bottom of the movable guide rail 5. The two movable blocks 18 are respectively slidably installed in the movable grooves 17 opened in the fixed guide rail 4.

[0023] Through the sliding fit of the movable block 18 and the movable groove 17, the movable guide rail 5 can move left and right on the fixed guide rail 4.

[0024] Among them, the adjusting component is composed of a motor 14, a slide block 15 and a lead screw 16. The slide block 15 is fixedly connected to the side wall of the mounting plate 9 close to the movable guide rail 5. The slide block 15 is slidably installed in the slide groove 11 opened in the movable guide rail 5. A lead screw 16 is rotatably connected in the slide groove 11. The lead screw 16 passes through the slide block 15 and is connected to the slide block 15 through a threaded fit. A motor 14 is also fixedly embedded at the end of the movable guide rail 5. The output shaft of the motor 14 is fixedly connected to the center of the shaft end of the lead screw 16.

[0025] During use, since the mounting plate 9 is located in the middle above the inspection table 1 and is relatively far from the staff, it is not very convenient for the staff to manually control it. The motor 14 can be started to drive the lead screw 16 to rotate. Since the slider 15 is restricted by the chute 11 and cannot rotate, when the lead screw 16 rotates, the slider 15 will slide in the chute 11, thereby controlling the forward and backward movement of the mounting plate 9.

[0026] Among them, the lifting assembly is composed of a lead screw 16 and a mounting seat 13. A mounting seat 13 is fixedly connected to the side wall of the acquisition camera 8 close to the mounting plate 9. The mounting seat 13 is slidably connected to the lifting groove 12 opened in the mounting plate 9. An electric cylinder 10 is fixedly embedded in the upper end of the mounting plate 9, and the telescopic rod of the electric cylinder 10 is fixedly connected to the upper end of the mounting seat 13.

[0027] During use, by controlling the length of the telescopic rod of the electric cylinder 10, the height of the mounting seat 13 can be controlled, and then the height of the acquisition camera 8 can be controlled.

[0028] The present utility model provides an image acquisition mechanism for vision inspection, and the specific working principle is as follows:

[0029] During use, the workpiece to be inspected is placed on the inspection table 1. If the volume of the workpiece to be inspected is too large and the acquisition camera 8 cannot directly record all the images of the workpiece to be inspected, the acquisition camera 8 can be controlled to take pictures of the workpiece to be inspected from different positions through the cooperation of the sliding assembly, the adjusting assembly and the lifting assembly. Specifically, through the sliding fit of the movable block 18 and the movable groove 17, the movable guide rail 5 can move left and right on the fixed guide rail 4, thereby controlling the left and right movement of the acquisition camera 8. Since the mounting plate 9 is located in the middle above the inspection table 1 and is relatively far from the staff, it is not very convenient for the staff to manually control it. The motor 14 can be started to drive the lead screw 16 to rotate. Since the slider 15 is restricted by the chute 11 and cannot rotate, when the lead screw 16 rotates, the slider 15 will slide in the chute 11, thereby controlling the forward and backward movement of the mounting plate 9, and then controlling the forward and backward movement of the acquisition camera 8. By controlling the length of the telescopic rod of the electric cylinder 10, the height of the mounting seat 13 can be controlled, and then the height of the acquisition camera 8 can be controlled.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
