[0035] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figures 1 to 4 As shown, the visual inspection device of the utility model includes a body 1, a guide rail 2, a first inspection component 3, a second inspection component 4, a fill light box 5 and a first fill light 6. The visual inspection device is used for inspecting gloves. During the inspection, the glove mold and the gloves are driven by a conveyor chain to pass through for inspection.

[0037] like Figure 1 As shown, at least four guide rails 2 are provided on the machine body 1, and the four guide rails 2 are provided in parallel; at least two first detection components 3 are provided, one of which is slidably provided on two guide rails 2 on one side for detecting one side of the product, and the other first detection component 3 is slidably provided on the other two guide rails 2 for detecting the other side of the product;

[0038] As in the above technical solution, the first detection component 3 is slidably connected to the guide rail 2 on the body 1, so that the position of the detection component can be easily adjusted to adapt to the detection work of gloves on glove molds of different models. In addition, the setting of this structure makes the detection component an open structure, and each component is easy to observe and adjust, and convenient for disassembly and maintenance;

[0039] Specifically, the guide rail 2 is an optical axis, which is used for sliding adjustment of the first detection component 3 and the second detection component 4 .

[0040] The second detection assembly 4 is slidably disposed on the two guide rails 2 located in the middle, and the second detection assembly 4 is used for missed detection of products;

[0041] As described above, the second detection component 4 is used for missed detection of products to detect whether there are gloves on the glove mold, thereby facilitating the counting of the number of gloves and avoiding misoperation of the glove mold in subsequent processes.

[0042] Specifically, the first detection component 3 and the second detection component 4 are both industrial cameras.

[0043] Specifically, the second detection component 4 performs missed detection of products through color recognition. When the color detected during the photo shooting does not correspond to the color of the product, it determines that the product does not exist.

[0044] like Figure 1 and Figure 2As shown, the first detection component 3 includes a background plate 31 and a first camera 32, wherein the background plate 31 is slidably disposed on the guide rail 2; the first camera 32 is slidably disposed on the guide rail 2, and the first camera 32 is directly facing the background plate 31;

[0045] As shown in the above structure, in the first detection component 3, the background plate 31 and the first camera 32 can slide on the guide rail 2 independently. In this way, when adjustment is needed, the distance between the background plate 31 and the first camera 32 can be adjusted to allow molds of different sizes and models to pass through, thereby improving adaptability.

[0046] Specifically, the background plates 31 and the first cameras 32 of the two first detection components 3 are arranged in opposite positions;

[0047] As in the above structure, after the background plates 31 and the first cameras 32 of the two first detection components 3 are placed oppositely, after the glove mold drives the glove through, the first cameras 32 in the two first detection components 3 take a picture each, thereby realizing the detection of both sides of the glove.

[0048] like Figure 1 As shown, the fill light box 5 is slidably arranged on the guide rail 2, and the fill light box 5 is provided with an opening toward the background plate 31; the first fill light 6 and the first camera 32 are arranged in the fill light box 5;

[0049] As in the above structure, the fill light box 5 can slide on the guide rail 2, and the first fill light 6 and the first camera 32 are installed in the fill light box 5, so that the first camera 32 can be protected and light can be focused to ensure the photo detection effect.

[0050] like Figure 3 and Figure 4 As shown, the second detection component 4 includes a bracket 41, a second fill light 42 and a second camera 43, wherein the bracket 41 is arranged between the two first detection components 3, and the bracket 41 is slidably connected to the guide rail 2; the second fill light 42 is arranged on the bracket 41, and the fill light direction of the second fill light 42 intersects with the fill light direction of the first fill light 6; the second camera 43 is arranged on the bracket 41;

[0051] As in the above structure, in the second detection component 4, the bracket 41 is slidably arranged on the guide rail 2, and the second fill light 42 and the second camera 43 are arranged on the bracket 41, so that when the glove passes, the second camera 43 can take pictures to detect the missed gloves, and the position adjustment of the second detection component 4 can be achieved by sliding the bracket 41. At the same time, the second detection component 4 and the first detection component 3 share the slide rail, which can improve the compactness of the structure and reduce the production cost; at the same time, the fill light direction of the second fill light 42 intersects with the fill light direction of the first fill light 6, which can provide additional lighting when the first camera 32 performs detection, so as to ensure the accuracy of the detection result;

[0052] Furthermore, the surface of the bracket 41 on which the second fill light 42 is mounted is an inclined surface, so that the fill light direction of the second fill light 42 intersects with the fill light direction of the first fill light 6 .

[0053] Specifically, the bracket 41 is in a Y shape, and the lens of the second camera 43 faces the opening of the bracket 41;

[0054] As shown in the above structure, the shape of the bracket 41 facilitates the glove mold to drive the glove through, and also improves the convenience of the second camera 43 to detect the glove.

[0055] Two brackets 41 are provided, and the brackets 41 are hollow structures. The second camera 43 is provided on one of the brackets 41; an air inlet 401 and an air outlet 402 are provided on the other bracket 41;

[0056] As in the above structure, after two brackets 41 are set up, one of them is used to install the second camera 43 to detect missed gloves, and the other is used to connect the compressor. After the compressor is connected to the air inlet 401 of the bracket 41 through a pipeline, air flow can be blown through the air outlet 402 to remove debris on the surface of the gloves, thereby ensuring the accuracy of the detection.

[0057] Specific implementation steps:

[0058] As in the above structure, during the inspection, the conveying mechanism drives the glove mold and the glove to pass between the background plate 31 and the first camera 32 of the first inspection component 3. At this time, the first camera 32 takes a picture to inspect one side of the glove. Then, the glove passes through the second inspection component 4. The second camera 43 performs a missed inspection. Then, the compressor supplies air, and the air outlet 402 of the bracket 41 discharges air to purge the glove. After the purge, the glove passes through another first inspection component 3 to realize the inspection of the other side.

[0059] Preferably, a second detection component 4 is also provided in the direction where the gloves enter the detection device, and is used to connect to a compressor to blow air, so as to blow the gloves in advance to remove attachments;

[0060] Under the premise that the first camera 32 moves according to the second camera 43, that is, there is no glove on the glove mold, the first camera 32 does not detect. At this time, the second camera 43 can be arranged in the direction of entering the detection device; and under the premise that the first camera 32 detects at a fixed interval, the second camera 43 can be arranged between the two first detection components 3.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
