[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figures 1-4, the present utility model provides a technical solution: an injection molding product vision inspection device, including a vision labeling machine 1. A material distribution device 2 is arranged on one side of the vision labeling machine 1. A conveyor 3 is arranged at the upper ends of the vision labeling machine 1 and the material distribution device 2. On both sides of the top of the vision labeling machine 1, a first vision inspection mechanism 4 and a second vision inspection mechanism 5 are respectively arranged. A material distribution chute 6 is fixedly installed below one end of the conveyor 3 corresponding to one side of the vision labeling machine 1. A detection fixture 7 is arranged at the upper end of the conveyor 3. The rear surface of the top of the material distribution device 2 is fixedly connected with a mounting frame 8. A six-axis robot 13 is fixedly installed at the center of the front surface of the mounting frame 8. A gripper 9 is fixedly installed at one end of the six-axis robot 13. A material distribution mechanism 10 is fixedly installed at the upper end of the material distribution device 2.

[0015] Both the front surface and the rear surface of the conveyor 3 are fixedly connected with support frames. The number of support frames arranged is several. The bottoms of the support frames are respectively fixedly connected with the upper end surfaces of the vision labeling machine 1 and the material distribution device 2. These support frames provide stable support for the conveyor 3 to ensure its smooth operation.

[0016] The first vision inspection mechanism 4 is respectively composed of a first support plate, a first vision inspection camera and a first light source ring. The bottom of the first support plate is fixedly installed at the front-end position on one side of the top of the vision labeling machine 1. The first vision inspection camera is fixedly installed at the top position on the rear surface of the first support plate. The first light source ring is fixedly installed at the center position on the rear surface of the first support plate. The first vision inspection mechanism 4 conducts the first vision inspection on the injection molding product through the combination of its precise camera and light source ring, mainly detecting key features such as the screw teeth of the product to ensure the preliminary quality of the product. The design of its support plate ensures the stable installation and precise alignment of the inspection camera.

[0017] The second vision inspection mechanism 5 is respectively composed of a second support plate, a second vision inspection camera and a second light source ring. The second support plate is inclined. The bottom of the second support plate is fixedly installed at the front-end position on the other side of the top of the vision labeling machine 1. The second vision inspection camera is fixedly installed at the rear end of the top of the outer wall of the second support plate. The second light source ring is fixedly installed at the front-end position of the top of the outer wall of the second support plate. As a further inspection means, the second vision inspection mechanism 5 focuses on the labeling situation and its accuracy of the product through the inclined support plate and the precisely positioned light source ring and inspection camera to ensure that the appearance and quality of the product after labeling meet the standards.

[0018] The number of the material distribution chutes 6 is two. Both of the two material distribution chutes 6 are arranged in an inclined structure. The inclined structure of the material distribution chute 6 facilitates the product to automatically slide into different classification areas according to the inspection results, realizing the rapid classification and diversion of the product, improving the production efficiency and reducing the need for manual intervention.

[0019] The number of the detection jigs 7 is set to be several and they are evenly distributed. The several detection jigs 7 are fixedly installed on the conveyor belt of the conveyor 3, and the detection jigs 7 are used for placing the injection-molded products.

[0020] A first groove 11 and a second groove 12 are respectively formed in the front surface and the top of the detection jig 7. The first vision camera and the second vision camera can respectively detect the products on the detection jig 7 through the first groove 11 and the second groove 12.

[0021] Working principle: After the system is started, the products produced by the injection molding machine are placed into the feeding device 2 by the gripper 9 controlled by the six-axis robot 13. Then, the feeding device 2 places the products into each detection jig 7 on the conveyor 3. When the products move along with the conveyor belt, they are first detected by the first vision detection mechanism 4. The first vision detection mechanism 4 uses a precise vision detection camera and a light source ring combination to perform the first vision detection on key features such as the screw teeth of the products through the second groove 12 on the first support plate to ensure the preliminary quality of the products. Subsequently, the products continue to move forward. After entering the labeling area, the vision labeling machine 1 performs the labeling operation on the products. After the labeling is completed, the products enter the detection range of the second vision detection mechanism 5. The second vision detection mechanism 5 further detects the labeling situation and its accuracy of the products by using the first groove 11 through its inclined second support plate, the second vision detection camera and the second light source ring to ensure that the appearance and quality of the products meet the standards after labeling. After the detection is completed, the products continue to move forward along the conveyor 3 and are classified by the sorting chute 6 for the detected products.

[0022] In summary: For this visual detection device for injection-molded products, through the design of the feeding device 2, the conveyor 3, the first vision detection mechanism 4, the second vision detection mechanism 5, the detection jig 7, the gripper 9, the sorting mechanism 10 and the six-axis robot 13, through the precise feeding of the feeding device 2 and the efficient transmission of the conveyor 3, the automatic flow of the injection-molded products is realized, the manual intervention is reduced, and the production efficiency and the smoothness of the product flow are improved. The first vision detection mechanism 4 and the second vision detection mechanism 5 perform visual detection on the products in the detection jig 7 from multiple angles and work in parallel without interference, greatly improving the comprehensiveness and accuracy of the detection, ensuring the consistency and stability of the product quality. The six-axis robot 13 is equipped with the gripper 9 to achieve precise grasping and placing from the molding machine to the sorting mechanism 10, reducing the damage risk during the product transfer process and improving the accuracy and automation level of the operation.
