[0028] Combined with appendix Figure 1 To be continued Figure 5 This application relates to a visual image acquisition mechanism, which includes a conveying component 1100, a first image acquisition component 2100, and a first mirror imaging component 3100. The conveying component 1100 includes a conveyor belt or a conveyor chain plate, and the first image acquisition component 2100 and the first mirror imaging component 3100 are provided on at least one side of the conveying component 1100.

[0029] The conveying assembly 1100 is used to convey bottles. The mirror of the first mirror imaging assembly 3100 images the surface of the bottle. The mirror of the first mirror imaging assembly 3100 is arranged vertically. The first image acquisition assembly 2100 is located at the end of the first mirror imaging assembly 3100 away from the conveying assembly 1100. The first image acquisition assembly 2100 includes a camera and is used to acquire images from the first mirror imaging assembly 3100.

[0030] It should be noted that the first image acquisition component 2100 sends the acquired image to the host computer, which analyzes the image data to determine whether there are defects on the surface of the bottle.

[0031] Furthermore, in conjunction with the appendix Figure 3 and attached Figure 4 The visual image acquisition mechanism includes a first light source component 4100. At least one side of the conveying component 1100 is provided with the first light source component 4100. The first light source component 4100 illuminates the bottle to increase the brightness of the bottle surface and improve the image clarity of the first image acquisition component 2100.

[0032] Understandably, in conjunction with the appendix Figure 2 To be continued Figure 4 The visual image acquisition mechanism includes a base 1201, on which a first image acquisition component 2100, a first mirror imaging component 3100, and a first light source component 4100 are all mounted. In some examples, the base 1201 is arranged on both sides of the conveying component 1100 so that the first image acquisition component 2100, the first mirror imaging component 3100, and the first light source component 4100 can be arranged on both sides of the conveying component 1100.

[0033] In one implementation, at least two first mirror imaging components 3100 and first light source components 4100 are provided on the same side of the conveying component 1100. The first mirror imaging components 3100 and first light source components 4100 are distributed at intervals. The first mirror imaging components 3100 and first light source components 4100 are reasonably arranged on the base 1201 to achieve uniform lighting and avoid shadows, and to avoid obstructing the image in the first mirror imaging component 3100.

[0034] It is understood that on the same side of the conveying component 1100, at least two first image acquisition components 2100 are provided, and each first mirror imaging component 3100 is equipped with a first image acquisition component 2100.

[0035] In some examples, along a central line of symmetry perpendicular to the conveying direction of the conveying assembly 1100, the positions of each first light source assembly 4100 are symmetrically distributed on the same side of the conveying assembly 1100, improving the uniformity of lighting. (See attached diagram.) Figure 4 In some examples, four first light source components 4100 are configured on the same side of the delivery component 1100.

[0036] In some examples, the positions of the first light source components 4100 on both sides of the conveying component 1100 are symmetrically distributed along a central symmetry line parallel to the conveying direction on the conveying component 1100, thereby improving the uniformity of lighting on both sides of the bottle.

[0037] In one implementation, both the first image acquisition component 2100 and the first mirror imaging component 3100 are mounted on the base 1201 via a first bracket. Specifically, the first image acquisition component 2100 is mounted on the base 1201 via one first bracket, and the first mirror imaging component 3100 is mounted on the base 1201 via another first bracket.

[0038] Furthermore, the first light source assembly 4100 is mounted on the base 1201 via a first bracket.

[0039] In some examples, combined with appendix Figure 5The first bracket is provided with a vertical mounting slot to adjust the height of the first image acquisition component 2100, the first mirror imaging component 3100, or the first light source component 4100. Specifically, the first bracket includes a base plate and a vertical plate, with the vertical plate erected on the base plate and the mounting slot disposed on the vertical plate.

[0040] Understandably, the first bracket is fixedly connected to the base 1201. Specifically, the bottom of the first bracket is fixed to the upper surface of the base 1201 via a connector. The connector is provided as a screw or bolt, and the connector securely connects the base plate and the base 1201.

[0041] In some examples, the upper surface of the base 1201 is provided with an array of mounting holes, and the first bracket is fixed to the base 1201 by connectors inserted into the mounting holes. It should be noted that by selecting different mounting holes, the first bracket can be installed at multiple locations on the base 1201 or the position of the first bracket on the base 1201 can be changed.

[0042] In some examples, combined with appendix Figure 5 The bottom of the first bracket has an oblong hole that extends circumferentially around the center of the bottom of the first bracket. Specifically, the oblong hole is located on the base plate of the first bracket, and the connector passes through the oblong hole and is fixedly connected to the base 1201. It can be understood that when the connector is in the pre-tightened state, the first bracket can rotate due to the cooperation between the oblong hole and the connector, thereby adjusting the direction of the first image acquisition component 2100, the first mirror imaging component 3100, or the first light source component 4100.

[0043] Furthermore, the bottom of the first bracket has two waist-shaped holes.

[0044] As one implementation method, in conjunction with the appendix Figure 3 and attached Figure 4 The visual image acquisition mechanism includes a second image acquisition component 2200 and a second mirror imaging component 3200. At least one side of the conveying component 1100 is provided with both the second image acquisition component 2200 and the second mirror imaging component 3200. The area of ​​the bottle near the bottom is displayed on the mirror surface of the second mirror imaging component 3200. The second image acquisition component 2200 includes a camera and is used to acquire images from the second mirror imaging component 3200.

[0045] Specifically, the second image acquisition component 2200 is located above the second mirror imaging component 3200. The mirror of the second mirror imaging component 3200 is arranged at an angle, and the lower end of the mirror of the second mirror imaging component 3200 is closer to the conveying component 1100 than the upper end. The mirror of the second mirror imaging component 3200 is tilted upwards.

[0046] Referring to the accompanying drawings, in some examples, on the same side of the transport assembly 1100, a second mirror imaging assembly 3200 is provided, and the second mirror imaging assembly 3200 is located at the line of symmetry of each of the first mirror imaging assemblies 3100.

[0047] In some examples, combined with appendix Figure 4 and attached Figure 5 The visual image acquisition mechanism includes a second light source assembly 4200, which illuminates the area near the bottom of the bottle. The second light source assembly 4200 is located between the second mirror imaging assembly 3200 and the conveying assembly 1100. It should be noted that, compared to the first light source assembly 4100, which illuminates the sides of the bottle, the second light source assembly 4200 is positioned lower than the first light source assembly 4100, and is disposed on the upper surface of the base 1201.

[0048] In one embodiment, the second image acquisition component 2200 is mounted on the base 1201 via a second bracket, and the second mirror imaging component 3200 is mounted on the second bracket where the second image acquisition component 2200 is located.

[0049] The second bracket is fixedly connected to the base 1201. Specifically, the bottom of the second bracket is fixed to the upper surface of the base 1201 by a connector. The connector is a screw or bolt.

[0050] In some examples, the second bracket is provided with a vertical mounting slot to adjust the height of the second image acquisition component 2200 or the second mirror imaging component 3200. Specifically, the second bracket includes a base plate and a vertical plate, with the vertical plate erected on the base plate and the mounting slot disposed on the vertical plate.

[0051] In some examples, the second bracket is secured to the base 1201 via a connector inserted into a mounting hole on the base 1201.

[0052] In some examples, the bottom of the second bracket is provided with an oblong hole extending circumferentially around the center of the bottom of the second bracket. Specifically, the oblong hole is provided in the base plate of the second bracket, and the connector passes through the oblong hole and fixes the connecting base 1201. It is understood that when the connector is in the pre-tightened state, the second bracket can rotate due to the cooperation between the oblong hole and the connector, thereby adjusting the orientation of the second image acquisition component 2200 or the second mirror imaging component 3200.

[0053] Furthermore, the bottom of the second bracket has two waist-shaped holes.

[0054] Regarding the configuration of the second image acquisition component 2200 and the second mirror imaging component 3200, at least one alternative design is possible: the second image acquisition component 2200 is mounted on the base 1201 via a second bracket, and the second mirror imaging component 3200 is mounted on the base 1201 via another second bracket.

[0055] As one implementation method, in conjunction with the appendix Figure 2 The visual image acquisition mechanism includes a third image acquisition component 2300, which is located above the conveying component 1100. The third image acquisition component 2300 includes a camera for acquiring images of the top of the bottle.

[0056] Furthermore, in conjunction with the appendix Figure 2 The third image acquisition component 2300 is mounted above the conveying component 1100 via the top seat 1202, and the top seat 1202 is provided with a height adjustment component, which is connected to the third image acquisition component 2300 and is used to adjust the height of the third image acquisition component 2300.

[0057] In some examples, the height adjustment component adjusts the height of the third image acquisition component 2300 using a lead screw. Furthermore, the height adjustment component is equipped with a handwheel 2301, which allows the user to move the third image acquisition component 2300 up and down by turning the handwheel 2301.

[0058] In some examples, the height adjustment component includes a guide rod arranged vertically, and the third image acquisition component 2300 is slidably connected to the guide rod.

[0059] As one implementation method, in conjunction with the appendix Figure 1 The visual image acquisition mechanism includes a housing 1300. The housing 1300 is provided on at least one side of the conveying component 1100. The housing 1300 provides a closed space for image acquisition and avoids interference with mirror imaging.

[0060] Furthermore, the side wall of the cover 1300 is provided with an openable side door 1301, which is hinged to the cover 1300 by a hinge.

[0061] Combined with appendix Figure 1 In some examples, the conveying assembly 1100 is provided with a cover 1300 on both sides.

[0062] As one implementation method, in conjunction with the appendix Figure 4 The visual image acquisition mechanism includes at least one sensor 5000, which is disposed on the side of the conveying assembly 1100 and is used to monitor the position of the bottle in the conveying assembly 1100.
