DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] A visual inspection device for use with an automated production line for packaging products comprises an adjustment frame 301, wherein the adjustment frame 301 is arranged on one side of a production line 4, and a grabbing and transferring mechanism 1 is provided at a corner formed by the adjustment frame 301 and the production line 4; a detection mechanism 3 for imaging is installed on the adjustment frame 301, and a conveying mechanism 2 for conveying unqualified products is provided directly below the detection mechanism 3 for imaging, and the grabbing and transferring mechanism 1, the detection mechanism 3, and the conveying mechanism 2 are electrically connected to a controller respectively.

[0018] See attached Figure 1 The conveying mechanism 2 and the packaging production line 4 are distributed at a ninety-degree angle, the grabbing and transferring mechanism 1 is located inside the ninety-degree angle between the conveying mechanism 2 and the packaging production line 4, and the visual inspection mechanism 3 is located across the conveying mechanism 2 and in the front half thereof.

[0019] See attached Figure 2The grabbing and transferring mechanism 1 located inside the ninety-degree angle between the conveying mechanism 2 and the packaging production line 4 at least includes a fixed base 101 fixed on the ground, a handling robot 102 located on the fixed base 101, and a grabbing fixture 103 located at the end of the handling robot 102. The grabbing fixture 103 replaces different clamping blocks according to different product models to adapt to different product diameters.

[0020] See attached Figure 3 The conveying mechanism 2, which is distributed at a ninety-degree angle with the packaging production line 4, includes at least a supporting frame 01 fixed on the ground, a power transmission mechanism 202 fixed at one end of the frame for providing operating power for the conveying mechanism, a belt tensioning mechanism 204 fixed at the other end of the frame for adjusting the belt tension, and a conveying belt 203 spanning the power transmission mechanism 202 and the belt tensioning mechanism 204. In order to minimize the influence of external conditions on the camera's shooting effect, the belt color is matte black.

[0021] See attached Figure 4 The visual inspection mechanism 3, which is located across the conveying mechanism 2 and in the front half thereof, at least includes an adjustment frame 301 fixed on the ground, four groups of strip light sources 302 evenly distributed in the upper and lower parts of the adjustment frame 301 and can be adjusted according to actual conditions, three groups of inspection cameras evenly distributed on the top of the adjustment frame and can be adjusted according to actual conditions, and a display screen 304 located in the middle of the right side of the adjustment frame 301 and capable of displaying the photographing situation in real time.

[0022] The specific action process of the whole device is as follows:

[0023] 1. When the dialyzers are moved to the end of the packaging production line 4 after being bagged, the gripping fixtures 103 move with the handling robot 102 to evenly place the bagged products in two groups of four per column on the upper surface of the conveyor belt 203 of the conveyor mechanism 2 below the inspection mechanism 3, ensuring that the dust caps of the two groups of dialyzers to be inspected can be within the field of view of the three groups of cameras;

[0024] 2. After the grabbing and transporting mechanism 1 places the two groups of dialyzers at the pre-designed position, the four groups of bar light sources 302 receive the signal and start to illuminate the area where the two groups of dialyzers are located, preparing for the camera to take pictures in the next step. After the device detects that the four groups of bar light sources 302 are all turned on, the camera moves to take pictures of the positions where the dust caps of the two groups of dialyzers are located, and the visual detection mechanism 3 determines whether the dust caps exist and whether they deviate from the preset position. The real-time image of the photo and the detection results will be displayed in real time on the display screen 304;

[0025] 3. When the visual inspection mechanism 3 determines that all the dust caps of the two groups of dialyzers are in the preset position, the power transmission mechanism 202 is activated, and the transmission belt 203 is driven forward by cooperating with the belt tensioning mechanism 204, thereby driving the two groups of bagged dialyzer products that have passed the inspection to move forward to the next station;

[0026] 4. When the visual inspection mechanism 3 determines that the dust caps of the two groups of dialyzers deviate from the preset position or are lost, the display screen 304 gives an alarm message and transmits a signal to the handling robot 102. At this time, the grabbing and transferring mechanism 1 acts again, grabs the unqualified products and re-grabs the products on the packaging production line 4 to supplement the missing positions on the conveying mechanism 2. Repeat step 2 for re-judgment until both groups of products are tested and qualified, and then continue to repeat step 3.
