[0002] AOI (Automated Optical Inspection) equipment is used to detect defects in the image quality of a display screen. It uses optical properties to extract images of each pixel or sub-pixel of the panel, performs image analysis, and thus detects whether there are defects in each pixel or sub-pixel.

[0003] However, traditional AOI inspection equipment mostly relies on manual feeding, manual clamping of fixtures, and manual inspection of defective products using a magnifying glass. This results in low production efficiency, low inspection yield, and high labor costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional AOI inspection equipment mostly relies on manual feeding, manual clamping of fixtures, and manual inspection of defective products using a magnifying glass. This results in low production efficiency, low inspection yield, and high labor costs. The invention provides an AOI testing machine.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An AOI testing machine is provided, including a machine base. The machine base has a conveyor line composed of multiple first magnetic wheels along its length. The multiple first magnetic wheels are sequentially spaced along the width of the conveyor line. One side of the conveyor line is a loading section, above which an AOI inspection camera is located. The other side of the conveyor line is a unloading section. Below the unloading section is an NG lifting and traversing assembly composed of multiple second magnetic wheels, which can be lifted relative to the unloading section. A lifting cylinder assembly is provided at the bottom, and multiple second magnetic wheels are arranged sequentially at intervals along the length of the conveyor line. An NG buffer assembly is provided on one side of the unloading conveyor line segment. An NG buffer conveyor unit, consisting of multiple third magnetic wheels, is provided on the top of the NG buffer assembly, corresponding to the NG lifting and traversing assembly. The multiple third magnetic wheels are arranged sequentially at intervals along the length of the conveyor line. The NG buffer conveyor unit is sleeved on the NG buffer assembly, and the NG buffer assembly can be raised and lowered relative to the NG buffer conveyor unit.

[0007] Furthermore, the NG buffer assembly includes an NG buffer hopper and a lifting assembly located at the bottom of the NG buffer hopper for controlling the lifting and lowering of the NG buffer hopper. The NG buffer hopper includes two symmetrically spaced side frames. Multiple connecting plates are vertically symmetrically arranged in each of the two side frames. Multiple locking posts are horizontally symmetrically arranged from top to bottom between the two symmetrically arranged connecting plates and between the two side walls of the two symmetrically arranged side frames, and are spaced apart along the length of the conveyor line. The multiple locking posts are staggered from the multiple third magnetic wheels. The first lifting assembly includes two fixing plates respectively arranged on the outside of the two side frames. Each fixing plate has a lifting screw on the side opposite to the side frame for driving the NG buffer hopper. A drive motor for driving the lifting screw is provided at the bottom of the NG buffer hopper.

[0008] Furthermore, a first feed sensor is provided on the side of the feeding assembly line away from the unloading assembly line.

[0009] Furthermore, a second feed sensor is provided on the side of the unloading assembly line closest to the loading assembly line, and a positioning sensor is provided on the side of the unloading assembly line away from the loading assembly line.

[0010] Furthermore, a third inflow sensor is provided on the side of the NG buffer production line unit opposite to the NG lifting and traversing assembly, and a hopper error sensor is provided on the side of the NG buffer production line unit away from the NG lifting and traversing assembly.

[0011] Furthermore, each of the aforementioned locking posts is fitted with multiple anti-static O-rings.

[0012] Furthermore, multiple anti-static dust-free rollers are respectively fitted onto the first magnetic wheel, the second magnetic wheel, and the third magnetic wheel.

[0013] The AOI testing machine provided in the above embodiments of this utility model has a conveyor line composed of multiple first magnetic wheels along its length. One side of the conveyor line is a loading section, with an AOI inspection camera positioned above it. The other side is a unloading section, with an NG lifting and traversing assembly positioned below it that can be lifted relative to the unloading section. An NG buffer assembly is positioned on one side of the unloading section, and an NG buffer assembly unit is positioned on top of the NG buffer assembly, corresponding to the NG lifting and traversing assembly. The NG buffer assembly can be raised and lowered relative to the NG buffer assembly unit. Thus, after the product is inspected by the AOI inspection camera, it enters the unloading standby position to await feedback. When the feedback result is an NG product, it indicates an incoming material abnormality, and the NG lifting and traversing assembly can... The feeding line segment is lifted to raise NG products, which then flow into the NG buffer feeding line unit. Upon reaching a set position, the NG buffer component rises relative to the NG buffer feeding line unit, further raising the NG products. The NG buffer component then rises to the next storage position. When the feedback result is OK, the OK products flow into the feeding standby position for downstream equipment. This invention automatically feeds and inspects materials, allowing OK products to flow into downstream equipment while NG products are buffered and manually removed. AOI inspection cameras accurately identify incoming material anomalies, resulting in efficient and accurate automated operation at a lower cost. This improves production efficiency and effectively solves the problem of traditional AOI inspection equipment, which mostly relies on manual feeding, manual clamping of fixtures, and manual inspection of defective products using magnifying glasses, leading to low production efficiency, low inspection yield, and high labor costs.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the above as well. Figures 1 to 9An embodiment of this utility model provides an AOI testing machine, including a machine base 100. The machine base 100 has a conveyor line 200 along its length, consisting of multiple first magnetic wheels 201. The multiple first magnetic wheels 201 are sequentially spaced along the width of the conveyor line 200, forming a magnetic wheel group for conveying products 10. One side of the conveyor line 200 is a loading section 202. Products arrive at the loading section 202 from the previous process and flow into a waiting position. An AOI inspection camera 300 is located above the loading section 202. Products flowing into the waiting position wait for the previous product to complete its inspection before exiting the waiting position. The product is inspected by the AOI inspection camera 300. On the other side of the conveyor line is a discharge line segment 203. Below the discharge line segment 203 is an NG lifting and traversing assembly 400, composed of multiple second magnetic wheels 401, which can be lifted relative to the discharge line segment 203. At the bottom of the NG lifting and traversing assembly 400 is a lifting cylinder assembly 800, which drives the NG lifting and traversing assembly 400 to lift relative to the discharge line segment 203. Multiple second magnetic wheels 401 are arranged sequentially at intervals along the length of the conveyor line 200, forming a magnetic wheel group for conveying products. An NG is located on one side of the discharge line segment 203. The NG buffer assembly 500 has an NG buffer production line unit 600 on its top, corresponding to the NG lifting and traversing assembly 400, and composed of multiple third magnetic wheels 601. The multiple third magnetic wheels 601 are arranged at intervals along the length of the conveyor line 200, forming a magnetic wheel group for conveying products. The NG buffer production line unit 600 is fitted onto the NG buffer assembly 500, and the NG buffer assembly 500 can be raised and lowered relative to the NG buffer production line unit 600. Thus, after the product is inspected by the AOI inspection camera 300, it enters the unloading waiting position (i.e., enters the unloading production line segment 203) to await AOI inspection. The AOI inspection camera 300 provides feedback on the inspection result. When the AOI inspection camera 300 returns an NG (Not Good) product, it indicates an incoming material abnormality. The NG lifting and traversing component 400, located below the unloading conveyor section 203, can lift the NG product relative to the unloading conveyor section 203, and then it flows into the NG buffer conveyor unit 600. After reaching a set position, it stops. The NG buffer component 500 rises relative to the NG buffer conveyor unit 600, lifting the NG product. The NG buffer component 500 rises to the next storage position. When the AOI inspection camera 300 returns an OK (Good) product, the OK product flows into the unloading standby position for downstream equipment. In this way, this utility model automatically feeds and inspects materials.OK products flow into downstream equipment, while NG products are buffered and manually removed. This allows for precise identification of incoming material anomalies using the AOI inspection camera 300. The automated operation is efficient, accurate, and cost-effective, thereby improving production efficiency.

[0026] In this embodiment, the NG buffer assembly 500 includes an NG buffer hopper 501 and a lifting assembly 502 located at the bottom of the NG buffer hopper 501 for controlling the lifting and lowering of the NG buffer hopper. The NG buffer hopper 501 includes two symmetrically spaced side frames 5011. Multiple connecting plates 5012 are vertically symmetrically arranged within each of the two side frames 5011. Multiple locking posts 5013 are horizontally symmetrically arranged from top to bottom between the two symmetrically arranged connecting plates 5012 and between the two side walls of the two symmetrically arranged side frames 5011, and are arranged at intervals along the length of the conveyor line 200. Thus, each layer of horizontally arranged locking posts 5013... Each layer forms a storage layer for storing products. Thus, the NG buffer hopper 501 forms multiple storage layers for storing products at intervals from top to bottom. Each vertically arranged layer has a locking post 5013 staggered from each of the third magnetic wheels 601. That is, each vertically arranged locking post 5013 is located between two pairs of the third magnetic wheels 601, allowing the NG buffer assembly line unit 600 to be fitted onto the NG buffer component 500, facilitating the lifting and lowering of the NG buffer assembly 500 relative to the NG buffer assembly line unit 600. Thus, when the AOI inspection camera 300 returns a NG product, the lower... The NG lifting and traversing assembly 400, located below the material flow line segment 203, can lift relative to the unloading flow line segment 203, raising the product and then flowing into the NG buffer flow line unit 600. After being driven by the third magnetic wheel 401 to a set position, it stops. At this time, the NG product is placed on the third magnetic wheel 401. The lifting assembly 502 includes two fixing plates 5021 respectively disposed on the outer sides of the two side frames 5011. Each fixing plate 5021 has a lifting screw 5022 on the opposite side of the side frame 5011 for driving the NG buffer hopper 500. The bottom of the NG buffer hopper 500 has a driving screw for... The drive motor 5023 of the lifting screw 5022 is configured such that when the NG buffer assembly 500 rises relative to the NG buffer production line unit 600, the NG buffer hopper 501 rises relative to the NG buffer production line unit 600, and the first horizontally arranged locking post 5013 of the NG buffer hopper 501 rises relative to the third magnetic wheel 401, thereby lifting the NG product from the third magnetic wheel 401 and placing the NG product on the first horizontally arranged locking post 5013. The NG buffer assembly 500 then rises to the next storage position, and so on. The NG products on the NG buffer hopper 501 can be manually removed.

[0027] In this embodiment, a first feed sensor 2021 is provided on the side of the feeding assembly line 202 away from the unloading assembly line 203 to facilitate feeding.

[0028] In this embodiment, a second feeding sensor 2031 is provided on the side of the unloading assembly line 203 close to the feeding assembly line 202, and a positioning sensor 2032 is provided on the side of the unloading assembly line 203 away from the feeding assembly line 202, to facilitate unloading.

[0029] In this embodiment, a third inflow sensor 603 is provided on the side of the NG buffer CV unit 600 opposite to the NG lifting and traversing assembly, and a hopper error sensor 604 is provided on the side of the NG buffer CV unit away from the NG lifting and traversing assembly, so that NG products can flow into the NG buffer production line unit 600 and stop after reaching the set position.

[0030] In this embodiment, each of the locking posts 5013 is fitted with a plurality of antistatic O-rings 5014.

[0031] In this embodiment, multiple antistatic dust-free rollers 700 are respectively fitted on the first magnetic wheel, the second magnetic wheel and the third magnetic wheel.

[0032] It should be noted that in this embodiment, each vertically arranged post 5013 has a baffle 5015 at its top, which is parallel to the post 5013. The two sides of the baffle 5015 are respectively connected between the tops of the two side frames 5011. In this way, when the NG product is placed on the first horizontally arranged post 5013, the baffle 5015 at the top prevents the NG product from falling.

[0033] It should be noted that, in this embodiment, the AOI inspection camera 300 is fixed on the feeding assembly line section 202 by a mounting bracket.

[0034] The AOI testing machine provided in the above embodiments of this utility model has a conveyor line composed of multiple first magnetic wheels along its length. One side of the conveyor line is a loading section, with an AOI inspection camera positioned above it. The other side is a unloading section, with an NG lifting and traversing assembly positioned below it that can be lifted relative to the unloading section. An NG buffer assembly is positioned on one side of the unloading section, and an NG buffer assembly unit is positioned on top of the NG buffer assembly, corresponding to the NG lifting and traversing assembly. The NG buffer assembly can be raised and lowered relative to the NG buffer assembly unit. Thus, after the product is inspected by the AOI inspection camera, it enters the unloading standby position to await feedback. When the feedback result is an NG product, it indicates an incoming material abnormality, and the NG lifting and traversing assembly can... The feeding line segment is lifted to raise NG products, which then flow into the NG buffer feeding line unit. Upon reaching a set position, the NG buffer component rises relative to the NG buffer feeding line unit, further raising the NG products. The NG buffer component then rises to the next storage position. When the feedback result is OK, the OK products flow into the feeding standby position for downstream equipment. This invention automatically feeds and inspects materials, allowing OK products to flow into downstream equipment while NG products are buffered and manually removed. AOI inspection cameras accurately identify incoming material anomalies, resulting in efficient and accurate automated operation at a lower cost. This improves production efficiency and effectively solves the problem of traditional AOI inspection equipment, which mostly relies on manual feeding, manual clamping of fixtures, and manual inspection of defective products using magnifying glasses, leading to low production efficiency, low inspection yield, and high labor costs.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
