Description

Technical Field

[0001] This utility model relates to the field of machine vision inspection platforms, specifically a machine vision inspection platform for surface defects in agricultural sheet metal parts. Background Technology

[0002] By acquiring images of the surface of agricultural sheet metal parts using equipment such as industrial cameras, ensuring that the images are clear and accurate and can reflect the true condition of the surface, and combining machine vision with other sensor technologies such as laser ranging, ultrasonic testing, and X-ray testing, multi-dimensional information acquisition and fusion can be achieved. This enables more comprehensive and accurate detection of various defects in agricultural sheet metal parts, improving the reliability and effectiveness of the inspection. Therefore, the inspection of the surface quality of agricultural sheet metal parts is of paramount importance.

[0003] Currently, in the traditional agricultural sheet metal parts inspection process, the sheet metal parts need to be placed directly on the inspection platform, and their lower surface is in close contact with the upper surface of the platform, which directly results in the inability to inspect the upper and lower surfaces of the sheet metal parts at the same time. Utility Model Content

[0004] The purpose of this invention is to provide a machine vision inspection platform for surface defects of agricultural sheet metal parts, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A machine vision inspection platform for surface defects of agricultural sheet metal parts includes a support platform, a vision control console fixedly installed on one side of the support platform, a first detector and a second detector fixedly installed at the center of the upper end of the support platform, and a suspended clamping assembly for positioning and clamping the sheet metal parts at the upper end of the support platform.

[0007] Preferably, the suspended clamping assembly includes fixed brackets, the lower ends of the two fixed brackets are fixedly installed on the upper end of the support platform near both sides, and a first fixed plate and a second fixed plate are respectively fixedly installed on the upper end of the two fixed brackets near one side.

[0008] Preferably, guide slide rods are fixedly installed on both ends of the opposite side of the first fixed plate and the second fixed plate, and guide sleeves are slidably sleeved on the outer side of each of the four guide slide rods.

[0009] Preferably, the outer sides of the four guide sleeves are respectively fixedly fitted with a first sliding clamp and a second sliding clamp, and the four guide sleeves are respectively located inside the first sliding clamp and the second sliding clamp near their respective ends.

[0010] Preferably, a clamping groove is provided at the center of the interior of the opposing sides of the first sliding clamp and the second sliding clamp.

[0011] Preferably, a micro motor is fixedly installed on one side of the first fixing plate near one end. The output shaft of the micro motor is sleeved inside the first fixing plate. The output shaft of the micro motor is driven by a bidirectional lead screw. The outer side of the bidirectional lead screw is rotatably sleeved inside the first sliding clamp and the second sliding clamp at one end. The end of the second fixing plate away from the micro motor is rotatably sleeved inside the second fixing plate at one end.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model enables the positioning and suspension clamping of sheet metal parts by moving the first sliding clamp and the second sliding clamp along the guide slide rod. The clamping grooves on the two clamps can accurately align and clamp the sheet metal parts. By cooperating with the first detector located above the sheet metal parts positioning and suspension clamping assembly and the second detector located below the sheet metal parts positioning and suspension clamping assembly, the upper and lower surfaces of the sheet metal parts can be fully inspected, avoiding the inability to inspect the upper and lower surfaces of the sheet metal parts at the same time and reducing the need for manual flipping of the sheet metal parts.

[0014] 2. This utility model, through the suspended clamping component, can adjust the distance between the first sliding clamp and the second sliding clamp. Compared with the traditional clamping method, it can adapt to sheet metal parts of different sizes, thereby achieving effective clamping of sheet metal parts of various specifications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figure 1 As shown, a machine vision inspection platform for surface defects of agricultural sheet metal parts includes a support platform 1, a vision control console 2 fixedly installed on one side of the support platform 1, a first detector 3 and a second detector 4 fixedly installed at the center of the upper end of the support platform 1, and a suspended clamping assembly 5 for positioning and clamping the sheet metal parts at the upper end of the support platform 1.

[0023] In a specific embodiment, the first detector 3 is located above the sheet metal part positioning and suspension clamping assembly 5, while the second detector 4 is located below the sheet metal part positioning and suspension clamping assembly 5. The first detector 3 and the second detector 4 inspect the sheet metal part from different angles. Based on the principle of machine vision, the built-in image acquisition device, such as a high-resolution CCD or CMOS camera, quickly captures image information of the sheet metal part surface. The acquired image data is quickly transmitted to the vision control console 2 via a data cable, such as a USB or Ethernet interface. The vision control console 2 has built-in professional image processing software that uses advanced algorithms, such as deep learning-based object detection algorithms like the YOLO system. Algorithms such as Faster R-CNN analyze images and compare them with pre-set standard templates or feature libraries to identify whether there are defects on the surface of sheet metal parts, such as scratches, holes, and deformations. They can also accurately determine the location, shape, size, and other parameters of the defects. The first detector 3 and the second detector 4 are common in existing technologies and will not be discussed in detail here. They are usually Pepperl+Fuchs' VOS2D general vision series, such as VOS2000 (280×960 pixel resolution) and VOS5000 (2560x2048 pixel resolution), which have high resolution and can meet the needs of high-precision inspection of sheet metal parts.

[0024] Please refer to Figures 1 to 4 As shown, as a technical optimization of this utility model, the suspended clamping assembly 5 includes a fixed bracket 51. The lower ends of the two fixed brackets 51 are fixedly installed on the upper end of the support platform 1 near both sides. The upper end of the two fixed brackets 51 is fixedly installed on one side respectively. The first fixed plate 52 and the second fixed plate 53 are fixedly installed on opposite sides of the first fixed plate 52 and the second fixed plate 53 near both ends. The outer sides of the four guide slide rods 56 are slidably sleeved with guide sleeves 59.

[0025] Furthermore, the outer sides of the four guide sleeves 59 are respectively fixedly fitted with the first sliding clamping plate 57 and the second sliding clamping plate 58, and the four guide sleeves 59 are respectively located at the inner ends of the first sliding clamping plate 57 and the second sliding clamping plate 58. The inner sides of the opposing sides of the first sliding clamping plate 57 and the second sliding clamping plate 58 are each provided with a clamping groove 510 near the center. A micro motor 54 is fixedly installed on one side of the first fixed plate 52 near one end. The output shaft of the micro motor 54 is sleeved inside the first fixed plate 52. The output shaft of the micro motor 54 is driven by a bidirectional lead screw 55. The outer sides of the bidirectional lead screw 55 are respectively rotatably sleeved inside the first sliding clamping plate 57 and the second sliding clamping plate 58 near one end. The end of the second fixed plate 53 away from the micro motor 54 is rotatably sleeved inside the second fixed plate 53 near one end.

[0026] In a specific embodiment, the micro motor 54 serves as a power source. When its output shaft rotates, it drives the bidirectional lead screw 55 to rotate. The bidirectional lead screw 55 is rotatably sleeved with the first sliding clamp 57 and the second sliding clamp 58. When the bidirectional lead screw 55 rotates, due to the threaded engagement, it drives the first sliding clamp 57 and the second sliding clamp 58 to move relative to or towards each other along the guide slide rod 56. The guide slide rod 56 provides a stable guide for the movement of the clamps, ensuring that the clamps can move in a straight line with precision. During the rotation of the bidirectional lead screw 55, the threaded action pushes the first sliding clamp 57 and the second sliding clamp 58 to move closer together along the guide slide rod 56, so that the clamping grooves 510 on the two clamps gradually approach each other and finally clamp the sheet metal part to be clamped, completing the clamping action.
