Description

Technical Field

[0001] This utility model relates to the field of chip quality testing technology, and more specifically, to AOI silicone testing equipment. Background Technology

[0002] In the electronics manufacturing industry, AOI (Automated Optical Inspection) silicone inspection equipment is widely used in chip quality inspection. This equipment automatically scans the chip using a high-definition CCD camera, acquiring image information in real time. It then accurately compares the test points with pre-stored pass / fail parameters in a database. After complex image processing algorithms, it outputs a pass / fail result. Our company's inspection equipment is developed based on this principle. Our products require adhesive application, and apart from the application area, other parts must not be contaminated by adhesive. Therefore, we developed a device to detect whether silicone is adhered to the pins. This device uses ultraviolet light to illuminate the tested component, causing the silicone on the component to fluoresce. The device is equipped with a camera connected to vision software. A product standard is set in the software, and the camera uploads real-time image information of the tested product. After comparison with the standard in the vision software, a conclusion can be drawn whether the tested product is good or defective.

[0003] Furthermore, current mainstream AOI silicone inspection equipment generally suffers from functional limitations, possessing only independent defect detection capabilities but lacking an automated sorting mechanism directly linked to the inspection results. This disconnect between inspection and sorting processes leads to a series of problems in actual production: First, after inspection, manual sorting and classification of products is required, increasing labor costs on the production line. Moreover, manual operation is subject to subjective judgment, easily resulting in misjudgments of defect types and mixing of good and defective products, leading to inefficient subsequent repair processes and potentially causing batch quality issues due to misjudgments. Second, manual sorting speed lags far behind equipment inspection efficiency. In large-scale production scenarios, this often results in an accumulation of products awaiting sorting, creating a production line bottleneck and severely restricting capacity expansion.

[0004] In summary, existing AOI silicone testing equipment suffers from significant shortcomings in production efficiency and quality control due to the lack of a supporting automated sorting mechanism. There is an urgent need to achieve integrated testing and sorting functions through technological innovation in order to adapt to the development trend of high efficiency and intelligence in the modern electronics manufacturing industry.

[0043] Example:

[0044] Please see Figure 1-5The AOI silicone testing equipment includes a workbench 1 and a computer 17. The workbench 1 is equipped with a sorting table 2 and a feeding pipe 3. All test pieces are dropped sequentially from the feeding pipe 3 at set times. The sorting table 2 has a sliding pipe 4 connected to the feeding pipe 3. A mounting base 5 is located on the side of the sliding pipe 4 on the sorting table 2. A supplementary light tube 6 is mounted on the mounting base 5, positioned at an angle downwards to emit ultraviolet light to irradiate the area where the silicone droplets on the test piece are located, causing fluorescence. A CCD camera 7 is located at the upper end of the sliding pipe 4. The CCD camera 7 is electrically connected to the computer 17. The CCD camera 7 is used to acquire and upload graphic information of the inspected part. The computer 17 is equipped with vision software, which stores standard-specification information of the inspected part. By comparing two patterns, the computer determines whether the current inspected product is good or defective. The computer 17 also has a pre-set control program that is linked with the vision software. The vision software generates a good / defective judgment signal by comparing the standard part data. This signal is converted into an electrical signal by the relay module inside the computer 17 and transmitted to the drive motors of push rod 9 and push rod 16, respectively. Specifically:

[0045] If the test result is a defective product, the computer 17 sends a high-level signal to the push rod 9, driving the motor of the push rod 9 to rotate in the forward direction, causing the output end of the push rod 9 to extend, and completing the extension and reset action within 0.5s;

[0046] If the test result is good, the computer 17 sends a low-level signal to the push rod 16, driving the motor of the push rod 16 to rotate in the opposite direction, causing the output end of the push rod 16 to retract, and completing the retraction and reset action within 0.3s.

[0047] A sorting row 8 is located on the sorting table 2, below the sliding tube 4. A sorting chute 801 is installed on the sorting row 8. The part to be inspected is fed from the feed pipe 3, falls through the sliding tube 4 into the sorting chute 801. The sorting chute 801 serves as the sorting channel for transporting the part to the good product tube 11 or the defective product tube 12. A push rod 9 is installed inside the sorting chute 801, and the triggering method of the push rod 9 is related to the inspection result of the part. The output end of the push rod 9 is fixedly connected to a pusher head 10. Normally, the output end of the push rod 9 is retracted. When the inspection result of the part is defective, the output end of the push rod 9 extends, pushing the part to the leftmost side of the sorting chute 801 and falling into the defective product tube 12. The output end of the push rod 9 then retracts to its original position. The cycle time is ≤0.5s. The size and specifications of the pusher head 10 match the sorting chute 801. A rubber layer 1001 is fixedly connected to the end of the pusher head 10 away from the push rod 9, and the shape of the rubber layer 1001 matches the pusher head 10. The rubber layer 1001 can prevent the tested part from being damaged by impact after it comes into contact with the tested part. A good quality tube 11 and a defective tube 12 are provided at the lower end of the sorting row 8. The good quality tube 11 is coaxially arranged with the sliding tube 4. The defective tube 12 is located on the far left of the sorting row 8. The diameter of the sliding tube 4, the good quality tube 11, and the defective tube 12, as well as the specifications of the sorting chute 801, all match the size and specifications of the tested part. The sorting chute 801 is connected to the tube inlet of the good quality tube 11 and the defective tube 12 respectively. A material blocking component is provided at the outer end of the good quality tube 11.

[0048] The material blocking assembly includes a vertical plate 13 perpendicular to the good quality tube 11. The vertical plate 13 has a communicating groove 1301 and a through hole 1302. The specifications of the through hole 1302 match the diameters of the sliding tube 4 and the good quality tube 11. A slider 14 is slidably connected within the groove 1301. A stop block 15 is fixedly connected to the front end of the slider 14. The front end of the stop block 15 is parallel to the sorting row 8 and is made of a flexible material. A push rod 16 is located at the top inner end of the groove 1301. Both push rod 19 and push rod 16 are miniature electric push rods. The output end of push rod 16 is connected to the slider 14. The push rod 16 is fixedly connected. Under normal circumstances, the output end of the push rod 16 is extended so that the stop block 15 blocks the through hole 1302 and the tube inlet of the good quality tube 11. The test piece falling into the sorting chute 801 will also stop at the stop block 15. When the test result of the test piece is good, the output end of the push rod 16 retracts, driving the slider 14 and the stop block 15 to move upward synchronously until the stop block 15 can no longer block the through hole 1302. At this time, the test piece that is judged to be good will automatically fall into the good quality tube 11, and the output end of the push rod 16 will then extend and reset. The cycle of this action is ≤0.3s.

[0049] Working principle: When using this equipment to perform quality inspection on products after dispensing, the part to be inspected will fall to the sorting chute 801. The part to be inspected at the sorting chute 801 is illuminated by a UV lamp emitted by the supplementary light tube 6, causing the silicone on the part to fluoresce. The real-time image information of the part to be inspected is obtained by the CCD camera 7. This image information is compared with the standard parts stored in the vision software to determine whether it is a good or defective product. When the inspection result is a good product, the output end of the push rod 16 retracts, driving the slider 14 and the stop block 15 to move upward synchronously until the stop block 15 can no longer block the through hole 1302, so that the part to be inspected that is a good product will automatically fall into the good product tube 11. When the inspection result is a defective product, the output end of the push rod 9 will extend, pushing the part to be inspected to the leftmost side of the sorting chute 801, so that it will automatically fall into the defective product tube 12, thus completing the sorting of good and defective products. Compared with existing technologies, this utility model eliminates the need for manual intervention in the sorting process, significantly reducing labor costs on the production line. The automated discrimination mechanism based on standard part data comparison can prevent misjudgments caused by subjective human judgment. At the same time, it improves sorting speed compared to manual sorting, effectively solving the problem of product accumulation in large-scale production, and enabling the detection and sorting processes to form a closed-loop linkage, thereby increasing production capacity.

[0050] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
