Abstract
Description
Technical Field
[0001] This invention specifically relates to the field of AOI testing technology, and more specifically to an intelligent AOI testing device. Background Art
[0002] In modern manufacturing, product quality control is crucial. With the rapid development of industries such as electronics, automobiles, and medical devices, the complexity and precision of products are constantly increasing. Traditional manual inspection methods can no longer meet the requirements of production efficiency and inspection accuracy. AOI technology has emerged to address this need, utilizing optical imaging and computer vision technology to inspect products. However, existing AOI equipment still has some shortcomings. For example, during image acquisition, the imaging effect on objects with complex shapes and different materials is poor, resulting in limited inspection accuracy. In terms of image processing algorithms, the ability to distinguish certain minor defects or similar defects is insufficient. Furthermore, the level of intelligence of the equipment needs to be improved; for instance, its adaptability is poor, it cannot quickly adapt to the inspection of different product models, and its data processing and analysis capabilities are insufficient to effectively guide the optimization of the production process.
[0003] The main function of the automated optical microscope inspection equipment for wafers is to perform wafer defect inspection according to customer needs. It utilizes high-resolution cameras, machine vision technology and AI algorithms, and various inspection methods (AQL sampling, multi-zone sampling, and tightened inspection) to automatically detect wafer scratches, pits, bumps, dirt, chipping, probe marks, fuse, and ink spots. It replaces manual operation, improves wafer inspection speed and accuracy, reduces false detection rate, and automatically reports, stores and analyzes data through self-developed software, and then compares the detected defects with those of the end customer.
[0004] In current wafer inspection processes, wafers need to be manually placed onto the inspection tray before inspection, which is time-consuming and labor-intensive. Manual loading may cause surface damage or static electricity to the product, thus failing to effectively guarantee product quality. Summary of the Invention
[0005] The purpose of this invention is to provide an intelligent AOI testing device. In this device, the products to be tested are automatically fed through a vibration feeding structure, thereby reducing contact between people and products and reducing the possibility of product damage and static electricity. During the feeding process, a rotating frame is driven to rotate along the outer shell by a rotating shaft. This causes a sliding rod on a fixed rod at one end of a boss on the rotating frame to drive a downward pressing spring to contact the pressure plate. When the pressure plate moves downward, it compresses a third spring, causing a telescopic rod to drive a connecting rod to press down one end of the cam body. This causes the other end of the cam body to drive an upper push block to push the product between the two conveyor belts onto a placement surface. In the tank, the product is adsorbed through the cooperation of the negative pressure port and the negative pressure tube. When the rotating frame rotates, the negative pressure port and the negative pressure tube separate, and the tank rotates to the inner wall of the outer shell, effectively preventing the product from falling. When the product rotates to the upper notch, it is inspected by the detection structure. The inspected product is placed into the second transmission structure through the material handling component. When a defective product is found during inspection, a rotating robotic arm transfers the defective product to the collection device inside the second mounting cover. This structure achieves automated product feeding and transmission, reducing manual intervention and minimizing product damage. It also reduces the occurrence of static electricity and other issues, thus effectively improving production efficiency and solving the problems mentioned in the background technology.

[0018] As a further technical solution of the present invention, the bottom of the U-shaped frame and the Z-shaped frame are fixedly installed on the first support frame;
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In use, the product is placed in the vibrating feeding structure, and the product is transferred to the first transmission structure by vibration. At the same time as the vibrating feeding, the drive motor drives the rotating shaft to make the rotating frame rotate along the inside of the shell. During the rotation of the rotating frame, the cooperation between the lower pressure spring and the lower pressure structure is realized, thereby effectively realizing the linkage effect between the lower pressure structure, the cam structure and the upper top structure, and realizing the effect of automatic feeding.
[0021] 2. In this invention, during product loading, the rotating frame rotates, and the fixed rod at the end of the boss simultaneously drives the lower pressing spring, the sliding rod, and the first spring to rotate in the cavity inside the convex ring. When the boss rotates to coincide with the lower notch, the rotating frame pauses for 1-2 seconds. Under the action of the first spring, the lower pressing spring drives the sliding rod to move downward, so that the lower pressing spring passes through the lower notch and contacts the pressure plate, thereby driving the pressure plate to move downward. At the same time, the telescopic rod at the bottom of the pressure plate moves downward, so that the arc groove in the cam body at one end of the telescopic rod where the lever is installed deflects downward. When the position of the arc groove deflects, the position of the lever moves simultaneously, thereby squeezing the fourth spring at the end of the telescopic rod, achieving the effect of moving the lever back and forth and up and down, and driving the upper top structure.
[0022] 3. In this invention, when the cam body rotates upward under the drive of the lever, the cam body contacts the bottom of the upper block, realizing the upward push of the upper block by the cam body. When the upper block moves upward, the ear plates on both sides of the upper block press the second spring upward along the connecting rod, thereby realizing the upper block lifting the product between the two conveyor belts in the first transmission structure upward, realizing the product entering the placement groove opened on the boss. At this time, the negative pressure port opened inside the placement groove coincides with the negative pressure pipe, and the product is adsorbed in the placement groove by negative pressure. After the product is placed, the upper block moves downward to reset under the action of the second spring, and at the same time, the cam body is pressed downward to reset. The cam body realizes the lever moves backward to reset under the action of the fourth spring and the telescopic rod through the arc groove. At the same time, the pressure plate slides upward along the fixed rod under the action of the third spring. Since the lower pressure spring is arc-shaped and is set when the rotating frame rotates, it retracts into the concave cavity inside the convex ring by pressing the slide rod and the first spring.
[0023] 4. In this invention, after the product is placed, the rotating frame rotates again under the drive of the drive motor to adsorb the next product. When the rotating frame rotates, the negative pressure port separates from the negative pressure tube, and the product is located on the inner side of the inner wall of the placement slot and the outer shell, thereby effectively preventing the product from falling. When the next placement slot of the rotating frame rotates to coincide with the lower notch, the above action is repeated to achieve the automatic feeding effect of the product.
[0024] 5. This invention: When the product in the placement slot rotates to the upper notch, the product is inspected by the detection structure. After inspection, the second electric push cylinder drives the slide plate to move forward along the top of the Z-shaped frame, so that the negative pressure suction plate coincides with the placement slot at the upper notch. Then, the first electric push cylinder drives the negative pressure suction plate to move downward, so that the negative pressure suction plate contacts the product. Then, the negative pressure pipe draws negative pressure from the negative pressure suction plate to remove the product from the placement slot. The first electric push cylinder returns to its original position, and the second electric push cylinder drives the slide plate to move backward along the Z-shaped frame, so that the inspected product in the negative pressure suction plate is placed on the second transmission structure and transferred to the next process. During the inspection process, the inspection equipment transmits the signal of non-conforming products to the rotary robotic arm. The rotary robotic arm removes the non-conforming products transferred from the second transmission structure and places them into the collection device set in the second mounting cover, so as to separate the qualified products from the non-conforming products and ensure the smooth progress of subsequent work.

[0051] One end of the boss 810 is fitted with a corresponding fixing rod 813; a sliding rod 815 is slidably installed at the end of the fixing rod 813 away from the boss 810; a downward pressing spring 814 is fixedly installed at the bottom of the sliding rod 815; the downward pressing spring 814 is arc-shaped; a first spring 816 is sleeved on the sliding rod 815 between the fixing rod 813 and the downward pressing spring 814.
[0052] A pressing structure 85 is fixedly installed on both sides of the lower notch 803; the pressing structure 85 includes two symmetrically arranged fixed rods 850; a pressure plate 851 is slidably installed on the fixed rods 850; an L-shaped plate 853 is fixedly installed in the middle of the bottom of the pressure plate 851; a telescopic rod 855 is slidably installed on the L-shaped plate 853; a lever 856 is provided at one end of the telescopic rod 855; a fourth spring 854 is sleeved between the end of the telescopic rod 855 away from the lever 856 and the L-shaped plate 853.
[0053] By adopting the above technical solution, when in use, the product 15 is placed in the vibratory feeding structure 4, and the product 15 is transferred to the first transmission structure 12 by vibration. At the same time as the vibratory feeding, the drive motor 86 drives the rotating shaft 82 to make the rotating frame 81 rotate along the inside of the outer shell 80. During the rotation of the rotating frame 81, the cooperation between the lower pressing spring 814 and the lower pressing structure 85 is realized, thereby effectively realizing the linkage effect between the lower pressing structure 85, the cam structure 84 and the upper lifting structure 83, and realizing the effect of automatic feeding.
[0054] Please see Figure 16-22 The pressing structure 85 is connected to the cam structure 84; the cam structure 84 includes two symmetrical mounting plates 840; the mounting plates 840 are fixedly installed with the first transmission structure 12; a cam body 841 is provided between the two mounting plates 840; the cam body 841 is movably installed with the mounting plates 840 via a rotating shaft 842; an arc-shaped groove 8410 is also provided on the cam body 841; a lever 856 is installed in the arc-shaped groove 8410.
[0055] In this embodiment, the cam structure 84 is connected to the upper push structure 83; the upper push structure 83 includes an upper push block 830; ear plates 833 are fixedly installed on both sides of the upper push block 830; the ear plates 833 are slidably installed with the connecting rod 831; the top of the connecting rod 831 is fixedly installed with the frame of the first transmission structure 12, and a second spring 932 is sleeved on the connecting rod 831 between the frame of the first transmission structure 12 and the ear plates 833;
[0056] The first transmission structure 12 is provided with two transmission belts, and the gap between the two transmission belts is the same as the width of the upper block 830.
[0057] By adopting the above technical solution, during the loading of product 15, the rotation of the rotating frame 81 causes the fixing rod 813 at the end of the boss 810 to simultaneously drive the lower pressing spring 814, the sliding rod 815, and the first spring 816 to rotate in the cavity inside the convex ring 801. When the boss 810 rotates to coincide with the lower notch 803, the rotating frame 81 pauses for 1-2 seconds. Under the action of the first spring 816, the lower pressing spring 814 drives the sliding rod 815 to move downward, so that the lower pressing spring 814 passes through the lower notch 803 and presses against the lower notch 801. When the plate 851 contacts, it drives the pressure plate 851 to move downward. At the same time, the telescopic rod 855 at the bottom of the pressure plate 851 moves downward, causing the end of the telescopic rod 855 that is equipped with the lever 856 to press down on the arc groove 8410 in the cam body 841 to deflect downward. When the position of the arc groove 8410 deflects, the position of the lever 856 moves at the same time, thereby enabling the end of the telescopic rod 855 to squeeze the fourth spring 854, achieving the effect of the lever 856 moving back and forth and up and down, thus driving the upper top structure 83.
[0058] Please see Figure 2-14 In this embodiment, the feeding detection component 8 includes a rotating shaft 82; the rotating shaft 82 passes through the fixing plate 14 and the outer shell 80 and is fixedly installed with the rotating frame 81; the outer shell 80 and the rotating shaft 82 are installed in conjunction with the U-shaped frame 13; one end of the rotating shaft 82 away from the rotating frame 81 is connected to the drive motor 86; the drive motor 86 is fixedly installed with the end of the U-shaped frame 13.
[0059] In this embodiment, the fixing plate 14 is fixedly installed to the outer shell 80 via a plug rod; the end of the fixing plate 14 away from the outer shell 80 is fixedly installed to the material picking component 9; the material picking component 9 includes two symmetrical Z-shaped frames 93; a sliding plate 91 is slidably installed on the top of the Z-shaped frame 93; a first electric push cylinder 90 is fixedly installed on the bottom of the sliding plate 91; the push rod of the first electric push cylinder 90 passes through the sliding plate 91 and is fixedly installed to the negative pressure suction plate 94; one end of the negative pressure suction plate 94 is connected to the negative pressure pipe 11; one side of the sliding plate 91 is fixedly installed to the second electric push cylinder 92 via a connecting plate; the second electric push cylinder 92 is installed on one side of the Z-shaped frame 93 via a support plate;
[0060] By adopting the above technical solution, when the cam body 841 rotates upward under the drive of the lever 856, the cam body 841 contacts the bottom of the upper push block 830, thereby pushing the upper push block 830 upward. When the upper push block 830 moves upward, the ear plates 833 on both sides of the upper push block 830 press the second spring 832 upward along the connecting rod 831, thereby enabling the upper push block 830 to lift the product 15 between the two conveyor belts in the first transmission structure 12 upward, so that the product 15 enters the placement groove 811 opened on the boss 810. At this time, the negative pressure port 812 opened inside the placement groove 811 coincides with the negative pressure tube 11, and the product 15 is adsorbed in the placement groove 811 by negative pressure.
[0061] Please see Figure 1-16 In this embodiment, the negative pressure suction plate 94 is fitted with the upper notch 802 on the outer shell 80; the first transmission structure 12 is fitted with the lower notch 803; the negative pressure port 812 on the rotating frame 81 at the lower notch 803 of the outer shell 80 is fitted with the negative pressure pipe 11; the negative pressure pipe 11 at the negative pressure port 812 in the rotating frame 81 is connected to the negative pressure pipe 11 at the end of the negative pressure suction plate 94 and the negative pressure machine; a detection structure is also fitted on the top of the upper notch 802, and the detection structure is fixedly installed on the top of the inner side of the shell 1.
[0062] By adopting the above technical solution, after the product 15 is placed, the upper top block 830 moves downward and resets under the action of the second spring 832. At the same time, the lower cam body 841 resets downward. The cam body 841 realizes that the lever 856 moves backward and resets under the action of the fourth spring 854 and the telescopic rod 855 through the arc groove 8410. At the same time, the pressure plate 851 slides upward along the fixed rod 850 under the action of the third spring 852. Since the lower pressing spring 814 is arc-shaped and is set when the rotating frame 81 rotates, it retracts into the cavity inside the convex ring 801 by pressing the slide rod 815 and the first spring 816 through the lower pressing spring 814.
[0063] Furthermore, a second transmission structure 7 is fixedly installed between the two Z-shaped frames 93; the end of the second transmission structure 7 away from the material handling component 9 is fitted with the welding component 6; a rotary robotic arm 5 is also fitted on one side of the second transmission structure 7; the rotary robotic arm 5 can extend into the second mounting cover 3.
[0064] The U-shaped frame 13 and Z-shaped frame 93 are fixedly mounted on the first support frame 10 at their bottoms.
[0065] By adopting the above technical solution, after the product is placed, the rotating frame 81 rotates again under the drive of the drive motor 56 to achieve the adsorption of the next product. When the rotating frame 81 rotates, after the negative pressure port 812 separates from the negative pressure tube 11, the product 15 is located on the inner side of the inner wall of the placement slot 811 and the outer shell 80, thereby effectively preventing the product 15 from falling. When the next placement slot 811 of the rotating frame 81 rotates to coincide with the lower notch 803, the above action is repeated to achieve the automatic feeding effect of the product 15.
[0066] Furthermore, when the product in the placement slot 811 rotates to the upper notch 802, the product 15 is inspected by the detection structure. After the inspection is completed, the second electric push cylinder 92 drives the slide plate 91 to move forward along the top of the Z-shaped frame 93, so that the negative pressure suction plate 94 coincides with the placement slot 811 at the upper notch 802. Then, the first electric push cylinder 90 drives the negative pressure suction plate 94 to move downward, so that the negative pressure suction plate 94 contacts the product 15. Then, the negative pressure pipe 11 draws negative pressure from the negative pressure suction plate 94, so that the product 15 is removed from the placement slot 811. The first electric push cylinder 90... The device resets upwards, and then the second electric push cylinder 92 drives the slide plate 91 to move backward along the Z-shaped frame 93, so as to place the inspected product 15 in the negative pressure suction plate 94 onto the second transmission structure 7 and transfer it to the next process. During the inspection process, the inspection equipment transmits the non-conforming signal to the rotary robotic arm 5. The rotary robotic arm 5 takes out the non-conforming product transferred from the second transmission structure 7 and places it into the collection device set in the second mounting cover 3, so as to separate the qualified product from the non-conforming product and ensure the smooth progress of the subsequent work.
[0067] The working principle of this invention is as follows: When in use, the product 15 is placed in the vibrating feeding structure 4, and the product 15 is transferred to the first transmission structure 12 by vibration. At the same time as the vibrating feeding, the drive motor 86 drives the rotating shaft 82 to make the rotating frame 81 rotate along the inside of the outer shell 80. During the rotation of the rotating frame 81, the cooperation between the lower pressing spring 814 and the lower pressing structure 85 is realized, thereby effectively realizing the linkage effect between the lower pressing structure 85, the cam structure 84 and the upper lifting structure 83, and realizing the effect of automatic feeding.
[0068] During the loading of product 15, the rotation of the rotating frame 81 causes the fixing rod 813 at the end of the boss 810 to simultaneously drive the pressing spring 814, the sliding rod 815, and the first spring 816 to rotate in the cavity inside the convex ring 801. When the boss 810 rotates to coincide with the lower notch 803, the rotating frame 81 pauses for 1-2 seconds. Under the action of the first spring 816, the pressing spring 814 drives the sliding rod 815 to move downward, so that the pressing spring 814 passes through the lower notch 803 and connects with the pressure plate 851. The contact causes the pressure plate 851 to move downwards. At the same time, the telescopic rod 855 at the bottom of the pressure plate 851 moves downwards, causing the end of the telescopic rod 855 that is equipped with the lever 856 to press down on the arc groove 8410 in the cam body 841 to deflect downwards. When the position of the arc groove 8410 deflects, the position of the lever 856 moves simultaneously, thereby causing the end of the telescopic rod 855 to squeeze the fourth spring 854, achieving the effect of the lever 856 moving back and forth and up and down, thus driving the upper top structure 83.
[0069] When the cam body 841 rotates upward under the drive of the lever 856, the cam body 841 contacts the bottom of the upper push block 830, thereby pushing the upper push block 830 upward. When the upper push block 830 moves upward, the ear plates 833 on both sides of the upper push block 830 press the second spring 832 upward along the connecting rod 831, thereby enabling the upper push block 830 to lift the product 15 between the two conveyor belts in the first transmission structure 12 upward, so that the product 15 enters the placement groove 811 opened on the boss 810. At this time, the negative pressure port 812 opened inside the placement groove 811 coincides with the negative pressure tube 11, and the product 15 is adsorbed in the placement groove 811 by negative pressure.
[0070] After product 15 is placed, the upper block 830 moves downward and resets under the action of the second spring 832. At the same time, the lower cam body 841 resets downward. The cam body 841 realizes that the lever 856 moves backward and resets under the action of the fourth spring 854 and the telescopic rod 855 through the arc groove 8410. At the same time, the pressure plate 851 slides upward along the fixed rod 850 under the action of the third spring 852. Since the lower pressing spring 814 is arc-shaped and is set when the rotating frame 81 rotates, it retracts into the cavity inside the convex ring 801 by pressing the slide rod 815 and the first spring 816 through the lower pressing spring 814.
[0071] After the product is placed, the rotating frame 81 rotates again under the drive of the drive motor 56 to adsorb the next product. When the rotating frame 81 rotates, the negative pressure port 812 separates from the negative pressure tube 11, and the product 15 is located on the inner side of the inner wall of the placement slot 811 and the outer shell 80, thereby effectively preventing the product 15 from falling. When the next placement slot 811 of the rotating frame 81 rotates to coincide with the lower notch 803, the above actions are repeated to achieve the automatic feeding effect of the product 15.
[0072] When the product 15 rotates from the placement slot 811 to the upper notch 802, the detection structure detects the product 15. After detection, the second electric push cylinder 92 drives the slide plate 91 to move forward along the top of the Z-shaped frame 93, so that the negative pressure suction plate 94 coincides with the placement slot 811 at the upper notch 802. Then, the first electric push cylinder 90 drives the negative pressure suction plate 94 to move downward, so that the negative pressure suction plate 94 contacts the product 15. Then, the negative pressure pipe 11 draws negative pressure from the negative pressure suction plate 94, so that the product 15 is removed from the placement slot 811. The first electric push cylinder 90 then moves upward. The second electric push cylinder 92 drives the slide plate 91 to move backward along the Z-shaped frame 93, so that the inspected product 15 in the negative pressure suction plate 94 is placed on the second transmission structure 7 and transferred to the next process. During the inspection process, the inspection equipment transmits the non-conforming signal to the rotary robotic arm 5. The rotary robotic arm 5 takes out the non-conforming product transferred in the second transmission structure 7 and places it into the collection device set in the second mounting cover 3, so as to separate the qualified product from the non-conforming product and ensure the smooth progress of the subsequent work.
