Description
Technical Field

[0002] A joint, a communication term, is a device installed between cables, with certain insulation and sealing properties, enabling two or more cables to operate continuously. Joints have high requirements for dimensions and need to ensure accurate butt joint fitting. However, during the production and processing process, due to the influence of the processing equipment itself and some external factors, there will be a certain number of defective products. These defective products need to be detected and screened out after unified processing to ensure the qualified rate of the products leaving the warehouse. Currently, the common operation method is for workers to conduct a full inspection of the products with an electronic magnifying glass by eye. Long-term work will cause eye fatigue problems, and the manual detection efficiency is low. The detection accuracy will also naturally decrease with eye fatigue, resulting in an increase in errors. Some use cameras to collect images for automatic detection, but most of them are single-sided and single-shot image acquisitions, with low acquisition efficiency. In addition, most of them collect images in natural light or indoor light environments, and their clarity is easily affected by the changes in natural light and the polarized light of indoor lights, resulting in blurred images, unable to show the edge details of the products, and affecting the detection quality. Content of the Utility Model
[0003] The purpose of the utility model is to provide a rapid joint vision detection device, which can avoid the influence of changes in natural light and the polarized light of indoor lights, thereby obtaining clearer detection images and improving the detection quality.

Specific embodiments
[0020] 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 in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a quick connector vision inspection device, including a vibrating disk 1, in which a number of connectors to be inspected are vibrated and fed. The top output end of the vibrating disk 1 is connected and fixed with an electromagnetic feeding guide rail 2. The left lower side of the electromagnetic feeding guide rail 2 is provided with a workbench 3. The bottom of the workbench 3 is cross-symmetrically provided with a number of columns. The middle right side of the top of the workbench 3 is fixedly connected with an inspection bin 4. The top of the inspection bin 4 is fitted and fixed with a full illumination lamp (full-spectrum LED lighting lamp) 5. The output end of the full illumination lamp 5 extends downward into the inner side of the inspection bin 4 and cooperates with it in terms of lighting. A number of through holes are symmetrically arranged on the front and back sides of the inspection bin 4. The through holes are equidistantly arranged in the left-right direction. On the opposite side of the front and back of the through holes, a CCD vision measurement module 6 is fitted. The CCD vision measurement modules 6 are respectively fixedly clamped with the inspection bin 4 in the front and back. The left side of the top of the inspection bin 4 is fixedly connected with an electric push rod 7. The bottom output end of the electric push rod 7 extends downward into the inspection bin 4 and is slidably matched with it up and down. The bottom of the output end of the electric push rod 7 is fixedly connected with an L-shaped limiting rod 8. The right end of the bottom side of the L-shaped limiting rod 8 is fixedly connected with a rubber sleeve. The right side of the rubber sleeve is in extrusion fit with the connector to be inspected. The left side of the top of the workbench 3 is fixedly connected with a sorting bin 9. The center of the top of the sorting bin 9 is fitted and fixed with a signal processing module 10. The top of the signal processing module 10 is electrically matched with a signal receiving module 11. The signal receiving module 11 is electrically matched with a number of CDD vision measurement modules. The inner top of the sorting bin 9 is equipped with a sorting paddle 12 (the lower side of the rectangular paddle swings back and forth for sorting driven by a PLC-controlled motor). The sorting paddle 12 is electrically matched with the signal processing module 10. The front and back sides of the sorting paddle 12 are symmetrically provided with sorting slide rails 13. The sorting slide rails 13 are both fixedly connected with the workbench 3.
[0022] Anti-collision strips are fixed at the front, rear and upper edges on the inner side of the sorting slide rail 13. A layer of sliding film is covered and adhered to the opposite sides of the anti-collision strips so as to be in sliding fit with the joints to be detected, so that both sides of the joints to be detected are not damaged by friction during blanking.
[0023] The CCD vision measurement modules 6 are in a front-to-back pair and are numbered 1-5 in sequence from left to right. Each group of CCD vision measurement modules 6 transmits the detected result electrical signals to the signal receiving module 11 corresponding to the numbers. The CCD measurement technology is used to quickly obtain the multi-faceted characteristic dimensions, real-time measurement data and the edge contour feature lines of different position points of the product. The feature detection reflected in the CCD image of the product is compared through a powerful software algorithm, and an accurate judgment is made on the product size. When the material moves into the detection bin, the CCD starts taking pictures and outputs OK and NG signals respectively according to the detection results. When the material moves into the sorting bin, the material is screened out according to the NG and OK signals output by the CCD.
[0024] A dust-proof film is covered and adhered to the top of the signal receiving module 11. The dust-proof film adopts a multi-layer bonding design. Sealing gaskets are fixedly arranged around the outer edges of the opposite sides of the through ports. The inner sides of the sealing gaskets are in extrusion fit with the CCD vision measurement modules 6 to provide dust-proof protection for each device and perform flexible docking.
[0025] Working principle: In the present utility model, a full-illumination lamp 5 is arranged at the top of the detection bin 4 to provide a semi-closed stable illumination environment for the joints to be detected, avoiding the influence of the change of natural light and the polarized light of indoor lamps, so as to obtain a clearer detection image and improve the detection quality. In addition, it can replace the single repetitive detection work of manual labor and the single-side single-time acquisition of partial camera detection, perform multi-group synchronous detection on the product and bilateral comprehensive image acquisition, improve the detection efficiency, ensure the accuracy of the test process, and enhance the competitiveness of the enterprise. The movement track of the joints to be detected is simplified as follows: vibrating disk 1 (uniform feeding) - electromagnetic feeding guide rail 2 (constant-speed feeding) - detection bin 4 (the CCD vision measurement module 6 cooperates with the L-shaped limiting rod 8 to intercept some joints for multi-group synchronous measurement) - sorting bin 9 (sorting paddles 12 cooperate with the signal receiving and processing module to screen the joints back and forth) - sorting slide rail 13 (classified blanking).
[0026] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model.
