Description

Technical Field

[0001] The present invention specifically relates to the technical field of AOI testing, and in particular to an intelligent AOI testing device. Background Art

[0002] In modern manufacturing, product quality control is extremely important. 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 as the times require. It uses optical imaging and computer vision technology to inspect products. However, existing AOI equipment still has some shortcomings. For example, in the image acquisition process, the imaging effect of objects with complex shapes and different materials is not good, resulting in limited inspection accuracy. In terms of image processing algorithms, the ability to distinguish certain minor defects or similar defects is insufficient. In addition, the intelligence level of the equipment needs to be improved. For example, the adaptability is poor and it cannot quickly adapt to the inspection of products of different models. The data processing and analysis capabilities are not sufficient to effectively guide the optimization of the production process.

[0003] The main function of the wafer automatic optical microscope inspection equipment is to perform wafer defect inspection according to customer needs. It uses high-definition resolution cameras, machine vision technology and AI algorithms, and various inspection methods (AQL sampling, multi-zone sampling, and strict inspection) to automatically detect wafer scratches, pits, bumps, dirt, edge collapse, needle test marks, fuses, and ink spots, replacing manual operations, improving wafer inspection speed and accuracy, and reducing false detection rates. It also automatically reports data for storage and analysis through self-developed software, and subsequently completes inspection comparisons with end customers;

[0004] During the existing wafer inspection, the wafer needs to be manually placed on the inspection tray for inspection, which is time-consuming and labor-intensive. Manual loading may cause damage to the surface of the product and static electricity, which cannot effectively guarantee the quality of the product. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent AOI testing device. In this device, the product to be tested is automatically fed through a vibrating feeding structure, thereby reducing the contact between people and products, thereby reducing the situation of static electricity damaging the product. In the feeding process, the rotating frame is driven to rotate along the outer shell by the rotating shaft, so that the sliding rod on the fixed rod at one end of the boss arranged on the rotating frame drives the pressing spring sheet to contact the pressing plate. When the pressing plate moves downward, the third spring is squeezed, so that the telescopic rod drives the connecting rod to press down one end of the cam body, so that the other end of the cam body drives the upper push block to push the product between the two conveyor belts to the place In the slot, the product is adsorbed by the cooperation of the negative pressure port and the negative pressure tube. When the rotating frame rotates, the negative pressure port is separated from the negative pressure tube, and the placement slot is rotated to the inner wall of the shell, thereby effectively avoiding the product from falling. When the product rotates to the upper notch, the product is inspected and processed by the detection structure, and the inspected product is placed in the second transmission structure through the material taking component. When unqualified products appear in the inspection, the unqualified products are transferred to the collection device inside the second installation cover by the rotating mechanical arm; the above structure realizes the automatic loading and transmission of products, reduces manual participation, and reduces damage to products.

[0018] As a further technical solution of the present invention, the bottoms of the U-shaped frame and the Z-shaped frame are fixedly mounted on the first support frame;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, when in use, the product is placed in the vibration feeding structure, and the product is transmitted to the first transmission structure through vibration. While the vibration feeding is in progress, the driving motor drives the rotating shaft to realize the rotation of the rotating frame along the inside of the shell. During the rotation of the rotating frame, the cooperation between the pressing spring sheet and the pressing structure is realized, thereby effectively realizing the linkage effect between the pressing structure, the cam structure and the upper structure, and realizing the effect of automatic feeding;

[0021] 2. In the present invention, during product loading, the fixed rod at the end of the boss simultaneously drives the pressing spring sheet, the slide bar and the first spring to rotate in the concave cavity inside the convex ring through the rotation of the rotating frame. When the boss rotates to overlap the lower notch, the rotating frame pauses for 1-2S; the pressing spring sheet drives the slide bar to move downward under the action of the first spring, so that the pressing spring sheet 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 pressing cam body at one end of the telescopic rod installation lever deflects downward. When the position of the arc groove deflects, the position of the lever moves simultaneously, so that the fourth spring is squeezed at the end of the telescopic rod, so that the lever moves forward and backward and up and down, thereby driving the upper structure.

[0022] When the cam body rotates upward under the drive of the shift rod, the cam body contacts the bottom of the upper top block, so that the cam body pushes the upper top block upward. When the upper top block moves upward, the ear plates on both sides of the upper top block squeeze the second spring upward along the connecting rod, so that the upper top block pushes the products between the two conveyor belts in the first transmission structure upward, so that the products enter the placement groove opened on the boss. At this time, the negative pressure port opened in the placement groove coincides with the negative pressure tube, and the products are adsorbed in the placement groove by negative pressure. After the product is placed, the upper top block moves downward and resets under the action of the second spring, and the downward cam body resets downward. The cam body realizes the shift rod to move backward and 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 downward pressure spring sheet is arranged in an arc shape, when the rotating frame rotates, the downward pressure spring sheet squeezes the sliding rod and the first spring to realize the contraction into the concave cavity inside the convex ring.

[0023] 4. In the present invention, after the product is placed, the rotating frame is driven by the driving motor to rotate again to achieve the adsorption of the next product. When the rotating frame rotates, the negative pressure port is separated from the negative pressure tube, and the product is located inside the placement groove and the inner wall of the shell, thereby effectively preventing the product from falling. When the next placement groove of the rotating frame rotates to coincide with the lower notch, the above actions are repeated to achieve the automatic loading effect of the product;

[0024] 5. The present invention; when the product in the placement groove rotates to the upper notch, the product is inspected by the detection structure. After the inspection is completed, the second electric push cylinder drives the slide plate to move forward along the top of the Z-frame, so that the negative pressure suction plate coincides with the placement groove at the upper notch, and then the negative pressure suction plate is driven downward by the first electric push cylinder to contact the negative pressure suction plate with the product, and then the negative pressure suction plate is pumped with negative pressure through the negative pressure pipe to take the product out of the placement groove, the first electric push cylinder is reset upward, and then the second electric push cylinder drives the slide plate to move backward along the Z-frame, so that the product inspected in the negative pressure suction plate is placed on the second transmission structure and transmitted to the next process. During the inspection process, the inspection equipment transmits the unqualified inspection signal to the rotating mechanical arm, takes out the unqualified product transmitted in the second transmission structure by the rotating mechanical arm, and places it in the collecting device arranged in the second mounting cover by the rotating mechanical arm, so as to separate qualified products from unqualified products, thereby ensuring the smooth progress of subsequent work.

[0053] By adopting the above technical solution, when in use, the product 15 is placed in the vibration feeding structure 4, and the product 15 is transferred to the first transmission structure 12 by vibration. While the vibration feeding is in progress, the driving motor 86 drives the rotating shaft 82 to realize the rotation of the rotating frame 81 along the inside of the shell 80. During the rotation of the rotating frame 81, the cooperation between the pressing spring 814 and the pressing structure 85 is realized, thereby effectively realizing the linkage effect between the pressing structure 85, the cam structure 84 and the upper structure 83, and realizing the effect of automatic feeding.

[0055] In this embodiment, the cam structure 84 is connected with the upper structure 83; the upper structure 83 includes an upper block 830; the upper block 830 is fixedly installed with ear plates 833 on both sides; 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 the connecting rod 831 between the frame of the first transmission structure 12 and the ear plates 833 is sleeved with a second spring 932;

[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 top block 830;

[0057] By adopting the above technical solution, when loading the product 15, the fixed rod 813 at the end of the boss 810 simultaneously drives the downward pressing spring piece 814, the slide bar 815 and the first spring 816 to rotate in the concave cavity inside the convex ring 801 through the rotation of the rotating frame 81. When the boss 810 rotates to overlap the lower notch 803, the rotating frame 81 pauses for 1-2 seconds; the downward pressing spring piece 814 drives the slide bar 815 to move downward under the action of the first spring 816, so that the downward pressing spring piece 814 penetrates the lower notch 803 and the pressure spring piece 814 is engaged with the pressure spring piece 814. The plate 851 contacts the pressing plate 851, thereby driving the pressing plate 851 to move downward. At the same time, the telescopic rod 855 at the bottom of the pressing plate 851 moves downward, so that one end of the telescopic rod 855 on which the lever 856 is installed presses 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 realizing that the end of the telescopic rod 855 squeezes the fourth spring 854, and the lever 856 moves forward and backward and up and down, thereby driving the upper structure 83.

[0058] See also Figure 2-14 ; In this embodiment, the feeding detection assembly 8 includes a rotating shaft 82; the rotating shaft 82 passes through the fixed plate 14 and the housing 80 and is fixedly installed with the rotating frame 81; the housing 80 and the rotating shaft 82 are installed in cooperation with the U-shaped frame 13; the end of the rotating shaft 82 away from the rotating frame 81 is connected to the driving motor 86; the driving motor 86 is fixedly installed with the end of the U-shaped frame 13;

[0059] In this embodiment, the fixed plate 14 is fixedly installed with the shell 80 through an insertion rod; the end of the fixed plate 14 away from the shell 80 is fixedly installed with the material picking assembly 9; the material picking assembly 9 includes two Z-shaped frames 93 that are facing each other; a slide plate 91 is slidably installed on the top of the Z-shaped frame 93; a first electric push cylinder 90 is fixedly installed at the bottom of the slide plate 91; the push rod of the first electric push cylinder 90 passes through the slide plate 91 and is fixedly installed with 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 slide plate 91 is fixedly installed with the second electric push cylinder 92 through a connecting plate; the second electric push cylinder 92 is installed on one side of the Z-shaped frame 93 through 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 top block 830, so that the cam body 841 pushes the upper top block 830 upward. When the upper top block 830 moves upward, the ear plates 833 on both sides of the upper top block 830 press the second spring 832 upward along the connecting rod 831, so that the upper top block 830 can lift the product 15 between the two conveyor belts in the first conveying 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 in 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.

[0062] By adopting the above technical solution, after the product 15 is placed, the upper block 830 moves downward and resets under the action of the second spring 832, and the pressing cam body 841 resets downward at the same time. The cam body 841 realizes the lever 856 to move backward and reset under the action of the fourth spring 854 and the telescopic rod 855 through the arc groove 8410. At the same time, the pressing plate 851 slides upward along the fixed rod 850 under the action of the third spring 852. Since the pressing spring sheet 814 is arranged in an arc shape, when the rotating frame 81 rotates, the pressing spring sheet 814 squeezes the sliding rod 815 and the first spring 816 to shrink into the concave cavity inside the convex ring 801.

[0063] Furthermore, a second transmission structure 7 is fixedly installed between the two Z-shaped frames 93; one end of the second transmission structure 7 away from the material taking assembly 9 is installed in cooperation with the welding assembly 6; a rotating mechanical arm 5 is also installed in cooperation with one side of the second transmission structure 7; the rotating mechanical arm 5 can extend into the second mounting cover 3;

[0065] By adopting the above technical solution, after the product is placed, the rotating frame 81 is driven by the driving motor 56 to rotate again to achieve the adsorption of the next product. When the rotating frame 81 rotates, the negative pressure port 812 is separated from the negative pressure tube 11, and the product 15 is located on the inner side of the inner wall of the placement groove 811 and the shell 80, thereby effectively preventing the product 15 from falling. When the next placement groove 811 of the rotating frame 81 rotates to coincide with the lower notch 803, the above actions are repeated to achieve the automatic loading effect of the product 15.

[0066] Furthermore, when the product in the placement groove 811 rotates to the upper notch 802, the product 15 is detected by the detection structure. After the detection 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 groove 811 at the upper notch 802, and 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, and then the negative pressure pipe 11 is used to pump negative pressure on the negative pressure suction plate 94 to remove the product 15 from the placement groove 811. The first electric push cylinder 90 Reset upward, and then drive the slide plate 91 to move backward along the Z-shaped frame 93 through the second electric push cylinder 92, so as to place the product 15 that has been tested in the negative pressure suction plate 94 on the second transmission structure 7, and transmit it to the next process. During the testing process, the testing equipment transmits the unqualified detection signal to the rotating mechanical arm 5, and the unqualified products transmitted in the second transmission structure 7 are taken out by the rotating mechanical arm 5, and are placed in the collection device provided in the second installation cover 3 by the rotating mechanical arm 5, so as to separate the qualified products from the unqualified products, thereby ensuring the smooth progress of the subsequent work;

[0067] The working principle of the present invention is as follows: when in use, the product 15 is placed in the vibration feeding structure 4, and the product 15 is transferred to the first transmission structure 12 by vibration. While the vibration feeding is in progress, the driving motor 86 drives the rotating shaft 82 to realize the rotation of the rotating frame 81 along the inside of the housing 80. During the rotation of the rotating frame 81, the cooperation between the pressing spring sheet 814 and the pressing structure 85 is realized, thereby effectively realizing the linkage effect between the pressing structure 85 and the cam structure 84 and the upper structure 83, and realizing the effect of automatic feeding.

[0068] When loading the product 15, the fixed rod 813 at the end of the boss 810 simultaneously drives the pressing spring piece 814, the slide bar 815 and the first spring 816 to rotate in the concave cavity inside the convex ring 801 through the rotation of the rotating frame 81. When the boss 810 rotates to overlap the lower notch 803, the rotating frame 81 pauses for 1-2 seconds; the pressing spring piece 814 drives the slide bar 815 to move downward under the action of the first spring 816, so that the pressing spring piece 814 passes through the lower notch 803 and connects with the pressing plate 851. The pressing plate 851 is driven to move downward. At the same time, the telescopic rod 855 at the bottom of the pressing plate 851 moves downward, so that one end of the telescopic rod 855 on which the lever 856 is installed presses the arc groove 8410 in the cam body 841 downward, and when the position of the arc groove 8410 is deflected, the position of the lever 856 moves at the same time, so that the end of the telescopic rod 855 squeezes the fourth spring 854, and the lever 856 moves forward and backward and up and down, thereby driving the upper 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 top block 830, so that the cam body 841 pushes the upper top block 830 upward. When the upper top block 830 moves upward, the ear plates 833 on both sides of the upper top block 830 press the second spring 832 upward along the connecting rod 831, so that the upper top block 830 can lift the product 15 between the two conveyor belts in the first conveying 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 in 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 the product 15 is placed, the upper block 830 moves downward and resets under the action of the second spring 832, and the pressing cam body 841 resets downward at the same time. The cam body 841 realizes the lever 856 to move backward and reset under the action of the fourth spring 854 and the telescopic rod 855 through the arc groove 8410. At the same time, the pressing plate 851 slides upward along the fixed rod 850 under the action of the third spring 852. Since the pressing spring sheet 814 is arranged in an arc shape, when the rotating frame 81 rotates, the pressing spring sheet 814 squeezes the sliding rod 815 and the first spring 816 to shrink into the concave cavity inside the convex ring 801.

[0071] After the product is placed, the rotating frame 81 rotates again under the drive of the driving motor 56 to achieve the adsorption of the next product. When the rotating frame 81 rotates, the negative pressure port 812 is separated from the negative pressure tube 11, and the product 15 is located on the inner side of the inner wall of the placement groove 811 and the shell 80, thereby effectively preventing the product 15 from falling. When the next placement groove 811 of the rotating frame 81 rotates to coincide with the lower notch 803, the above actions are repeated to achieve the automatic loading effect of the product 15.

[0072] When the product in the placement groove 811 rotates to the upper notch 802, the product 15 is detected by the detection structure. After the detection 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 groove 811 at the upper notch 802, and then the first electric push cylinder 90 drives the negative pressure suction plate 94 to move downward to achieve the contact between the negative pressure suction plate 94 and the product 15, and then the negative pressure pipe 11 is used to pump negative pressure on the negative pressure suction plate 94 to remove the product 15 from the placement groove 811, and the first electric push cylinder 90 moves upward again. position, and then the second electric push cylinder 92 drives the slide plate 91 to move backward along the Z-shaped frame 93, so that the product 15 that has been inspected in the negative pressure suction plate 94 is placed on the second transmission structure 7 and transmitted to the next process. During the inspection process, the inspection equipment transmits the unqualified inspection signal to the rotating robotic arm 5, and the unqualified products transmitted in the second transmission structure 7 are taken out by the rotating robotic arm 5, and placed in the collecting device arranged in the second mounting cover 3 by the rotating robotic arm 5, so as to realize the separation between qualified products and unqualified products, thereby ensuring the smooth progress of subsequent work.
