Description

Technical Field

[0001] The invention belongs to the field of visual inspection, and specifically relates to a 48PIN transformer AOI visual inspection device and method. Background Art

[0002] In the electronics manufacturing industry, the trend of miniaturization and high performance of products is becoming increasingly prominent. As a key component of many electronic products, the quality and performance of 48PIN transformers are directly related to the quality of terminal products. For precision 48PIN transformers, traditional manual inspection methods are difficult to meet the current stringent requirements for inspection accuracy and reliability. Manual inspection is not only inefficient and difficult to keep up with the pace of large-scale production, but also prone to problems such as missed inspections and false inspections due to human factors, increasing the risk of defective products flowing into subsequent production links, thereby raising production costs and after-sales risks.

[0003] Traditional testing methods are difficult to flexibly adapt to different types of 48PIN transformers. Different types of transformers have differences in shape, size, and pin layout, and traditional testing agencies are unable to adjust the testing environment and conditions according to these differences, resulting in the inability to comprehensively and accurately test various types of transformers;

[0004] Due to the inability to flexibly adapt to different types of transformers, traditional testing agencies are prone to missing minor defects and inaccurate test data during the testing process, which greatly reduces the detection accuracy and reliability and cannot effectively guarantee product quality.

[0005] To this end, the present invention provides a 48PIN transformer AOI visual inspection mechanism and inspection method. Summary of the invention

[0024] A detection method for a 48PIN transformer AOI visual detection mechanism, the detection method comprising the following steps:

[0025] S1, stably placing the tray loaded with 48PIN transformers on the tray upper and lower mechanisms 101, and then starting the transfer mechanism 102 to perform the material taking action of the 48PIN transformers;

[0026] S2, the transfer mechanism 102 transfers the successfully captured 48PIN transformer to the material separation mechanism 103, and the material separation mechanism 103 quickly takes effect, firmly fixes the transformer by clamping, and successfully completes the material separation operation;

[0027] S3. The 48PIN transformer that has completed the material separation is pushed by the cam mechanism 104 and accurately pushed to the feeding mechanism 105;

[0028] S4, the feeding mechanism 105 smoothly pushes the 48PIN transformer to the inspection area of ​​the AOI visual inspection mechanism 106 to carry out the inspection work;

[0029] S5. After the inspection process is completed, the 48PIN transformer enters the unloading mechanism 107. The unloading mechanism 107 classifies and processes the good or bad products according to the inspection results of the products.

[0030] Working principle:

[0031] Tray placement and transformer transfer: The tray with the 48PIN transformer is placed steadily on the tray upper and lower mechanisms 101. At this time, the tray upper and lower mechanisms 101 will be fine-tuned according to the preset program to ensure that the tray is in the best position. At the same time, the transfer mechanism 102 is started, and its mechanical arm accurately locates the 48PIN transformer on the tray, and the transformer is stably grasped by vacuum adsorption or mechanical clamping to complete the transfer action.

[0032] Transfer and separation: The transfer mechanism 102 holds the 48PIN transformer and moves to the top of the separation mechanism 103 according to the set path, and accurately places the transformer at the specified position of the separation mechanism 103. The separation mechanism 103 then starts to work, and it separates multiple transformers one by one through a series of mechanical actions, such as opening and closing of the clamping jaws, and translation of the track, in preparation for the subsequent inspection process.

[0033] The cam mechanism 104 feeds the material to the feeding mechanism 105: the 48PIN transformers after being sorted by the sorting mechanism 103 will be received by the cam mechanism 104. The cam mechanism 104 uses its unique cam profile and motion law to push the transformers to the feeding mechanism 105 in an orderly manner. In the feeding mechanism 105, the transformers will be arranged in a certain way and wait to be sent to the detection area.

[0034] Feeding and visual inspection: The feeding mechanism 105 is started, and the 48PIN transformers are pushed smoothly one by one to the inspection area of ​​the AOI visual inspection mechanism 106. When the transformer enters the inspection area, the camera body 121 and the lens 9 work together to collect all-round images of the transformer. During the acquisition process, the light source body 12 will perform fill-in light operation according to the actual situation to ensure that the collected image is clear and accurate. At the same time, in order to ensure the accuracy of the detection effect, the detection angle of the lens 9 can be fine-tuned through the profile side panel 3 and the angle adjustment plate 8; by turning the hand wheel 10, the screw of the screw slide body 11 is driven to rotate, thereby driving the slide to move, and the distance position of the light source body 12 is adjusted to make it in the most suitable fill-in light position for the lens 9. The collected detection data will be transmitted to the terminal device in real time and analyzed and processed by professional software.

[0035] Unloading and material separation: After the 48PIN transformer has been inspected by the AOI visual inspection mechanism 106, it will be received and transported by the unloading mechanism 107. The unloading mechanism 107 determines whether the product is good or bad according to the inspection result fed back by the terminal equipment, and transports the two to different channels or containers through the mechanical diversion device to complete the material separation.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
