Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 One embodiment of the present invention is as follows: A high-precision AOI online inspection device for liquid crystal displays includes a body 1, a support foot 2 fixedly installed at the bottom of the body 1, an inspection device 3 fixedly installed at the top of the inner wall of the body 1, a conveyor wheel 4 rotatably installed at the bottom of the inner wall of the body 1, a motor 5 fixedly installed at the bottom of the inner wall of the body 1, the output end of the motor 5 fixedly installed with the conveyor wheel 4, the conveyor wheel 4 being connected by a transmission belt 6, and a leveling device being provided at the bottom of the inner wall of the body 1;

[0030] The leveling device includes a gear 7, a rotating column 8, a gear 9, a cylinder 10, a collar 11, a sliding rod 12, a push plate 13, a sliding column 14, a baffle 15, and a stop rod 16. Gear 7 is fixedly installed on the end of the conveyor wheel 4 near the motor 5. The rotating column 8 is rotatably installed on the bottom of the inner wall of the machine body 1. Gear 9 is fixedly installed on the circumference of the rotating column 8. The cylinder 10 is fixedly installed on the top of the rotating column 8. The collar 11 is slidably installed on the top of the rotating column 8. The sliding rod 12 is fixedly installed on the right side of the collar 11. The push plate 13 is fixedly installed on the end of the sliding rod 12 away from the collar 11. The sliding column 14 slides through the push plate 13. The baffle 15 is fixedly installed on the end of the sliding column 14 away from the push plate 13. The stop rod 16 is fixedly installed on the back of the push plate 13. The sliding rod 12 pushes the push plate 13 to start moving. The movement of the push plates 13 at both ends pushes the display screen located on the conveyor wheel 4, so that the display screen is located in the middle position of the conveyor wheel 4, ensuring that the measuring instrument is within the optimal measuring range, thereby improving the accuracy and consistency of the measurement and improving the overall efficiency of the inspection.

[0031] Gear 7 meshes with gear 9. A spring is provided between push plate 13 and baffle 15. The meshing of gear 7 and gear 9 ensures that gear 7 can drive gear 9 to rotate together when it rotates. The spring ensures that baffle 15 can achieve self-reset.

[0032] In this embodiment, when the display screen reaches the top of the conveyor wheel 4 inside the machine body 1, the motor 5 is started, causing the motor 5 to drive the conveyor wheel 4 to start rotating. The rotation of the conveyor wheel 4 drives the other conveyor wheels 4 to start rotating via the transmission belt 6. The rotation of the conveyor wheel 4 drives the first gear 7 to start rotating, which in turn drives the second gear 9 to start rotating. The rotation of the second gear 9 drives the rotating column 8 to start rotating, which in turn drives the cylinder 10 to start rotating. The rotation of the cylinder 10 drives the collar 11 to start sliding, which in turn drives the sliding rod 12 to start sliding. The sliding rod 12 pushes the push plate 13 to start moving. The movement of the push plates 13 at both ends pushes the display screen located on the conveyor wheel 4, positioning the display screen in the middle of the conveyor wheel 4. Positioning ensures the measuring instrument is within its optimal measurement range, thereby improving measurement accuracy and consistency, and enhancing overall testing efficiency. When the push plate 13 moves, it drives the sliding column 14 to move, which in turn drives the baffle 15 to move. If the display is tilted during the baffle 15's movement, the baffle 15 pushes the sliding column 14 in the opposite direction. At this time, the push plate 13 drives the stop rod 16 to move, which blocks a corner of the display, allowing the display to adjust its position during transport. This ensures the display can quickly move to the required position, saving manual adjustment time, improving overall testing efficiency, and preventing the display from being in a position or state that the testing device 3 cannot detect, thus preventing testing failure.

[0033] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a cleaning device is provided at the bottom of the inner wall of the machine body 1, and a buffer device is provided at the bottom of the inner wall of the machine body 1. The cleaning device includes a push rod 171, a support frame 172, an elastic telescopic rod 173, a cleaning rod 174, and an inclined block 175. The push rod 171 is fixedly installed on the top of the sliding rod 12, the support frame 172 is fixedly installed on the bottom of the inner wall of the machine body 1, the elastic telescopic rod 173 is fixedly installed on the bottom of the support frame 172, the cleaning rod 174 is fixedly installed on the movable end of the elastic telescopic rod 173, and the inclined block 175 is fixedly installed on the front of the cleaning rod 174. The movement of the inclined block 175 drives the cleaning rod 174 to start moving. The cleaning rod 174 moves and contacts the display on the conveyor wheel 4, ensuring that dust, fingerprints, oil stains and other impurities on the surface of the display can be effectively removed, keeping the display clean and ensuring that the image is clearly visible.

[0034] The cleaning device also includes a storage tank 176, a water pipe 177, a valve 178, a rotating ring 179, a protrusion 1710, two rotating rods 1711, a belt 1712, and two push blocks 1713 and 1714. The storage tank 176 is fixedly installed on the top of the support frame 172, the water pipe 177 is fixedly installed on the bottom of the storage tank 176, the valve 178 is fixedly installed on the circumferential surface of the water pipe 177, the rotating ring 179 is fixedly installed on the control end of the valve 178, and the protrusion 1710 is fixedly installed on the circumferential surface of the rotating ring 179. Two rotating rods 1711 are connected by a belt 1712. Two push blocks 1713 are fixedly installed on the back of the belt 1712, and push block 1714 is fixedly installed on the front of the belt 1712. The valve 178 is opened by rotating the ring 179, so that the cleaning agent stored in the storage tank 176 flows out through the water pipe 177 and is sprayed on the surface of the cleaning rod 174. This ensures that the cleaning rod 174 can significantly improve visibility and color reproduction, reduce glare and blur when cleaning the display screen, thereby improving the viewing experience.

[0035] The side of push rod 171 that contacts the inclined block 175 is set as an inclined surface. A spring 2 is provided between push block 1713 and valve 178. By setting the inclined surface, it is ensured that push rod 171 can smoothly push inclined block 175. By setting spring 2, it is ensured that push block 1713 can achieve self-reset.

[0036] The buffer device includes a push rod 181, an inclined rod 182, a slide plate 183, two inclined blocks 184, a flap 185, and a stop 186. The push rod 181 is fixedly installed on the back of the cleaning rod 174. The inclined rod 182 is slidably installed on the bottom of the inner wall of the machine body 1. The slide plate 183 is slidably installed on the bottom of the inner wall of the machine body 1. The two inclined blocks 184 are fixedly installed on the top of the slide plate 183. The flap 185 is rotatably installed between the two inclined blocks 184. The stop 186 is fixedly installed on the bottom of the inner wall of the machine body 1. The movement of the flap 185 moves the display together, ensuring that the display can be smoothly and safely transferred to the next stage during the transportation process, reducing physical damage to the display and lowering the risk of breakage.

[0037] The buffer also includes two rotating rods 187, a belt 188, a fixing rod 189, a buffer plate 1810, and a connecting rod 1811. The two rotating rods 187 are rotatably mounted on the bottom of the inner wall of the body 1 and are connected by the belt 188. One end of the fixing rod 189 is fixedly mounted on the back of the slide plate 183, and the other end is fixedly mounted on the front of the belt 188. The buffer plate 1810 is slidably mounted on the bottom of the inner wall of the body 1. One end of the connecting rod 1811 is fixedly mounted on the back of the belt 188, and the other end is fixedly mounted on the left side of the buffer plate 1810. The movement of the rod 1811 causes the buffer plate 1810 to start moving. The movement of the buffer plate 1810 restricts the sliding area of ​​the display, ensuring that the display slides from the flip plate 185 to the safe area, effectively reducing the risk of accidental collisions and impacts, and preventing the display from sliding into the danger zone and colliding, causing damage.

[0038] The side of push rod 181 that contacts the inclined rod 182 is set as an inclined surface, the side of inclined rod 182 that contacts the inclined block 184 is set as an inclined surface, and a spring 3 is set between the slide plate 183 and the bottom of the inner wall of the machine body 1. The inclined surfaces ensure that push rod 181 can smoothly push inclined rod 182, the inclined rod 182 can smoothly push inclined block 184, and the spring 3 ensures that the slide plate 183 can achieve self-reset.

[0039] In this embodiment, during operation: As the sliding rod 12 slides, it drives the push rod 171 to move. The movement of push rod 171 pushes the inclined block 175 to move, which in turn drives the cleaning rod 174 to move. The cleaning rod 174 then contacts the display on the conveyor wheel 4, effectively removing dust, fingerprints, oil, and other impurities from the display surface, keeping the display clean and ensuring clear image visibility. The movement of the cleaning rod 174 also pushes the push block 1714 to move, which in turn drives the belt 1712 to move. Rotating around two rotating rods 1711, belt 1712 rotates, causing push block 1713 to move. Push block 1713 moves, causing protrusion 1710 to move. Protrusion 1710 moves, causing rotating ring 179 to rotate. Rotating ring 179 opens valve 178, allowing cleaning agent stored inside storage tank 176 to flow out through water pipe 177 and spray onto the surface of cleaning rod 174. This ensures that cleaning rod 174 can significantly improve visibility and color reproduction, reduce glare and blur when cleaning the display screen, thereby improving the viewing experience, especially in bright environments.

[0040] When the monitor moves to the top of the flip plate 185, the cleaning rod 174 moves simultaneously, causing the push rod 181 to move. The push rod 181 then moves the inclined rod 182, which in turn moves the inclined block 184. The inclined block 184 then moves the slide plate 183, which in turn moves the flip plate 185. The flip plate 185 moves the monitor along with the monitor, ensuring a smooth and safe transfer to the next stage during transport, reducing physical damage and the risk of breakage. As the flip plate 185 moves, it contacts the stop 186 and begins to rotate and tilt, ensuring the monitor's stability. The monitor can slide off the flip-up plate 185, reducing direct contact with other objects and preventing collisions and scratches with the next monitor if it fails to move in time. When the slide plate 183 moves, it drives the fixed rod 189 to move. The movement of the fixed rod 189 drives the belt 188 to rotate around the two rotating rods 187. The rotation of the belt 188 drives the connecting rod 1811 to move. The movement of the connecting rod 1811 drives the buffer plate 1810 to move. The movement of the buffer plate 1810 restricts the sliding area of ​​the monitor, ensuring that the monitor slides from the flip-up plate 185 to a safe area, effectively reducing the risk of accidental collisions and impacts, and preventing the monitor from sliding into a dangerous area and colliding with it, causing damage.
