Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, and in particular to a visual inspection device for electronic connectors. Background Technology

[0002] Vision inspection equipment for electronic connectors is a type of advanced inspection system specifically designed for the electronics manufacturing industry. Its main function is to ensure the high-quality manufacturing and reliability of electronic connectors through image capture, processing, and analysis. These devices play a crucial role in modern electronics production, helping manufacturers improve product quality, increase production efficiency, and ensure that products meet stringent specifications.

[0003] Chinese Publication No. CN111965189A discloses an AOI (Automated Optical Inspection) device for electronic screens. The device includes a main body with a rotating disk, a visual inspection mechanism, and an electrical testing needle mold mechanism. The rotating disk is rotatably connected to the center of the top surface of the main body. The rotating disk has several inspection stages, with the visual inspection mechanism corresponding to one of the inspection stages. The electrical testing needle mold mechanism includes multiple needle mold detection components, which are respectively arranged along the edge of the inspection stage located at the visual inspection mechanism. This design allows for electrical testing of the electronic screen's wiring without obstructing the visual inspection mechanism's view, integrating appearance inspection and electrical testing into one unit. This facilitates equipment miniaturization, reduces space requirements, and allows for seamless and efficient completion of both inspections, improving production efficiency. While this structure offers convenience in inspection, it is less convenient for subsequent processing of product conformity and non-conformity, requiring further assessment and processing based on the degree of defect.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0052] In order to improve product quality and production efficiency by inspecting electronic connectors and to help manufacturers better meet market demands, this application proposes a visual inspection device for electronic connectors to meet these requirements.

[0053] For reference Figure 1 This application mainly consists of a conveyor 1 for conveying electronic connectors, a detection component 3 for detecting electronic connectors in the first layer, a clamping component 4 for clamping and transferring electronic connectors that have passed the first layer detection to a placement stage 5, and a ring-shaped detection component 6 for secondary detection of electronic connectors in multiple aspects.

[0054] For reference Figure 1 In order for the detection element 3 to scan and record each electronic conveyor on the conveyor 1, the conveyor belt of the conveyor 1 is divided at equal intervals, and multiple barcodes 2 are set at the dividing points; thereby, the detection element 3 records the first step of scanning of an electronic connector located in the area after scanning the barcode 2.

[0055] It should be noted that each barcode 2 is different. After each barcode 2 is scanned by the detector 3, only one electronic component in the area is recorded. When the detector 3 scans the second barcode 2, it records another electronic component in the corresponding area, and so on.

[0056] For reference Figure 2-3 The detection component 3 is composed of a frame 31, a first scanner 32, an illumination lamp 33, a camera 34, and a first sensor 35; the frame 31 is n-shaped and is fixedly installed at the front side of the conveying end of the conveyor 1.

[0057] A first scanner 32 is provided on the front side of the inner top wall of the frame 31. The barcode 2 that has been moved is first scanned by the first scanner 32. After scanning, the image captured by the camera 34 is transmitted to the electronic screen 10 through the first sensor 35 for judgment, and the structure is judged to be qualified.

[0058] To facilitate better detection by the camera 34 under various colored lights, the illumination lamp 33 is a color-changing lamp. To avoid shadows caused by one-sided lighting affecting the recording of the camera 34, two illumination lamps 33 are installed inside the frame 31 and arranged symmetrically to provide better lighting.

[0059] To further explain, the detection lights used may differ depending on the type of electronic component being tested. Therefore, appropriate lights can be selected based on the specific electronic component being tested. In some tests, surface defects of electronic components can be better observed under illumination of various colors. The colors of the lights used can be set. After the first scanner 32 scans the barcode 2, different lights can be used to illuminate it in sequence. Based on the data recorded by the camera 34 after illumination by different lights, the first sensor 35 transmits the data to the electronic screen 10 for further judgment and records the judgment result in the corresponding barcode 2.

[0060] Thus, the electronic connector that has been scanned for the first time by the detection component 3 is transported again by the conveyor 1; it is transported to the fixture 43, and a corresponding movement operation is performed based on the second scan of the fixture 43.

[0061] For reference Figure 4 The fixture 43 is composed of an x-axis electric cylinder 41, a y-axis electric cylinder 42, a fixture 43, and a second scanner 44. The x-axis electric cylinder 41 and the y-axis electric cylinder 42 are connected in a cross shape, and the movement of the two drives the linear movement of the fixture 43 in the left and right and up and down.

[0062] The fixture 43 carries a second scanner 44. After the conveyor 1 moves the electronic connector that has passed the first layer of screening, the second scanner 44 scans the barcode 2 again to know the status of the first detection by the tester 3. When the electronic connector fails the first test, it does not move further after being scanned by the second scanner 44. The second scanner 44 scans the next barcode 2. If the electronic connector recorded by the next barcode 2 is also unqualified, the fixture 43 still does not move until the second scanner 44 scans the barcode 2 that records a qualified electronic connector. Through automated control, the fixture 43 clamps and conveys the electronic connector to the placement table 5 for the next detection step. The unqualified electronic connector will move to the end of the conveyor 1, where a receiving mechanism is set to receive the unqualified electronic connector.

[0063] For reference Figure 5The electronic connector is positioned on the placement table 5 by the clamp 4 and then the second layer of testing is performed. In order to ensure that different electronic connectors can be stably positioned after being moved by the clamp, the placement table 5 is composed of two parts: a support base 51 and a positioning plate 52. The support base 51 is fixedly installed on the side of the conveyor 1 that is parallel to the clamp 43, so that the clamp 43 is more convenient to move and place the electronic connector.

[0064] After placement, the electronic connector is positioned by the positioning plate 52 to prevent left and right displacement. In order to adapt to the placement of various electronic connectors during testing by a single testing device, the positioning plate 52 is designed to be detachable. Thus, when the testing device changes the testing parts, a more suitable positioning plate 52 mold can be used. At the same time, a sensing chip is set in the positioning plate 52. By sensing the placement, the chip transmits electrical signals to the electronic screen 10, which controls the annular probe 6 to move to the upper side of the positioning plate 52 to work.

[0065] For reference Figure 5 An electric slide 7 is provided on the side of the support base 51, and a support rod 8 is fixedly installed on the slider of the electric slide 7. The support rod 8 is a bent design. Thus, when the annular probe 6 is supported by the support rod 8, the middle part of the annular probe 6 corresponds vertically to the middle part of the positioning plate 52.

[0066] For reference Figure 6 The ring-shaped detector 6 consists of a ring frame 61, a camera 62, side cameras 63, and a second sensor 64. The ring frame 61 is designed to better support and distribute the camera 62 and four side cameras 63. The camera 62 is located in the center of the ring frame 61, with its camera end facing the positioning plate 52, to further inspect the upper side of the electronic connector located on the positioning plate 52. The four side cameras 63 are equidistantly distributed in a ring on the four sides of the ring frame 61, and are set at an angle towards the center of the positioning plate 52, to further inspect the four sides of the electronic connector during the inspection. This achieves the effect of multi-faceted inspection. The information recorded by the camera 62 and the side cameras 63 is transmitted to the electronic screen 10 through the second sensor 64 for judgment and calculation. Then, the control system in the electronic screen 10 controls the external mechanical shaft to distinguish between qualified and unqualified electronic connectors and place them in their respective storage areas.

[0067] It should be noted that before the robotic arm picks up the electronic connectors and places them separately, the electric slide 7 will move the annular detector 6, so that the upper side of the positioning plate 52 is not blocked, and the robotic arm can be placed in the empty positions on both sides of the positioning plate 52 to work.

[0068] Meanwhile, in complex inspection situations on one side, the electronic connector on the positioning plate 52 can be flipped by a robotic arm to inspect the reverse side.

[0069] It should be noted that, in order to enable the x-axis electric cylinder 41 to move on the upper side of the conveyor 1, support legs 9 are provided on both sides of the bottom of the x-axis electric cylinder 41 for support; and the electronic screen 10 of the load control system is installed on the support legs 9 for operation; the control system in the electronic screen 10 is used to control the start and stop movement between each group of equipment, as well as the judgment of the time detection results.

[0070] Meanwhile, to prevent errors during the repeated use of barcode 2, the control system automatically deletes all previously recorded data after the second scanner 44 scans the barcode and the control fixture 43 reacts accordingly. This prevents the previous set of detection data from reappearing during cyclical operation and thus avoiding affecting subsequent detection issues.

[0071] The specific operational steps of this application are as follows:

[0072] 1. First, place the electronic connectors to be tested into the areas defined by the conveyor 1 in a sequential manner. Each area has a barcode 2.

[0073] 2. Next, after the electronic connector is transported to the detection unit 3 in the area, the detection unit 3 first contacts the barcode 2 for scanning, thereby recording the detection status of the electronic connector in the area. The detected image and other information are transmitted to the electronic screen 10 through the first sensor 35. The electronic screen 10's control system then judges whether the data is qualified and records the information in the corresponding barcode 2.

[0074] 3. Next, the conveyor 1 continuously conveys the electronic connector. When the detector 3 scans the second barcode 2, it stops recording the electronic connector in the area of ​​the previous barcode 2 and repeats the conveying operation. When the electronic connector is conveyed to the underside of the fixture 4, the first inspection is determined by scanning the barcode 2 again. If it is not qualified, the fixture 4 does not move, and the unqualified electronic connector is continuously conveyed to the end of the conveyor 1. A bearing structure is set at the end of the conveyor 1 to support the unqualified electronic connector. If it is qualified, the fixture 4 moves and clamps the electronic connector on the placement table 5 for a second inspection.

[0075] 4. Finally, when the electronic connector is placed on the appropriate placement platform 5, the electric slide 7 starts to move, driving the ring detector 6 to move to the upper side of the placement platform 5 where the electronic connector is placed to perform detection. The ring detector 6 detects the electronic connector from multiple angles, and the image sensed by the ring detector 6 is transmitted to the electronic screen 10 and processed by the system to obtain a relative visual judgment result. Based on the structure, the external mechanical device is controlled to distinguish and place qualified products from unqualified products.

[0076] The above description is only for illustrating the present invention and should be understood as not being limited to the above embodiments. Various modifications that conform to the spirit of the present invention are within the protection scope of the present invention.
