[0014] The present invention provides an AOI optical online inspection device for a liquid crystal display circuit board production line. It has the following beneficial effects: (1) The invention places the circuit board to be inspected on the conveying device, and the conveying device drives the circuit board to move inside the main body. When the circuit board moves, it passes through the detector. When there is an error or omission in the components on the circuit board, the detector control module controls the No. 1 electric push rod and the No. 2 electric push rod to move, and the unqualified circuit board is pushed onto the rotating plate by starting the No. 1 electric push rod and the No. 2 electric push rod, and the unqualified circuit board is removed from the conveying device for collection, which can effectively prevent qualified and unqualified circuit boards from being mixed together. When the No. 1 electric push rod and the No. 2 electric push rod are started, the telescopic door is driven to move, and the movement of the telescopic door drives the baffle to move to close the left side of the main body, blocking the next circuit board from entering the main body, so as to avoid that when the unqualified circuit board is pushed away from the conveying device, it will affect the circuit board to be inspected at the rear, so that the circuit board at the rear is not fully inspected. When the circuit board is not fully inspected, unqualified circuit boards may be mixed with qualified circuit boards, which will reduce the qualified rate of products in subsequent inspections.

[0015] (2) In the present invention, when the No. 2 electric push rod is started, the No. 2 push plate will be driven to move. The movement of the No. 2 push plate will pull the soft rope. The pulling of the soft rope will pull the threaded rod to rotate. The rotation of the threaded rod will cause the volute spring to store force. When the threaded rod rotates, the sliding plate will slide downward. The sliding plate will drive the circuit board to move downward. The movement of the No. 2 push plate will pull the soft rope. The pulling of the soft rope will pull the threaded rod to rotate. The circuit board can be effectively and smoothly transported to the storage box, which effectively reduces the secondary damage to the circuit board during the transportation project and improves the possibility of subsequent repair. By pressing the gear shaft to engage with the gear, turning the handle to rotate the gear shaft drives the gear to rotate. When the gear rotates, it drives the threaded rod to rotate. At this time, the remaining circuit boards can be placed in the storage box to avoid missing parts in the subsequent repair process.

[0016] (3) In the present invention, the sliding rod will contact the inclined surface of the inclined plate when the slide rod slides. The contact between the sliding rod and the inclined surface of the inclined plate will push the inclined plate to slide upward. The upward sliding of the inclined plate will drive the square plate to move upward to release the obstruction of the storage box for collecting circuit boards. The square plate releases the obstruction of the storage box and can avoid blocking the circuit boards from entering the storage box when collecting the circuit boards. At the same time, when the square plate is in place, it can reduce the risk of the circuit boards sliding out of the storage box when the storage box is taken out for inspection. The return of the triangular rod to its original position will drive the first rotating rod and the second rotating rod to their original positions and push the circuit boards in the storage box into the storage slot, thereby temporarily fixing and storing the circuit boards and avoiding large movements during transportation that may cause the circuit boards to collide with the storage box and cause damage to the circuit boards. At the same time, it can also effectively avoid the accumulation of circuit boards. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed rod 190 and the inclined rod 189 are provided with inclined surfaces to facilitate the inclined rod 189 to push the fixed rod 190 to move upward to limit the storage box.

[0029] When the present embodiment is working, after the unqualified circuit board slides into the transport slot, it will fall on the surface of the sliding plate 174. When the next unqualified circuit board is reached, the pushing device will start again. When the pushing device starts, the No. 2 electric push rod 13 will start. The start of the No. 2 electric push rod 13 will drive the No. 2 push plate 11 to move. The movement of the No. 2 push plate 11 will pull the soft rope. The pulling of the soft rope will pull the threaded rod 171 to rotate. The rotation of the threaded rod 171 will cause the volute spring to store force. When the threaded rod 171 rotates, it will cause the sliding plate 174 to slide downward. The sliding downward movement of the sliding plate 174 will drive the circuit board to move downward. The sliding downward movement of the sliding plate 174 will contact with the No. 1 slider 175 above. When the inclined surface contacts, the sliding plate 174 contacts the inclined surface above the No. 1 slider 175, which will push the No. 1 slider 175 to move into the No. 1 moving groove. When the No. 1 slider 175 moves into the No. 1 moving groove, it will squeeze the No. 1 spring to store force. When the No. 1 slider 175 moves to a certain position, the latch rod 176 will be inserted into the fixed groove to limit the No. 1 slider 175. When the sliding plate 174 slides to the bottom of the collecting groove, it will squeeze the U-shaped plate 178 to slide into the No. 2 moving groove.

When the limit of the latch rod 176 is released, the limit of the No. 1 slider 175 will be released. When the limit of the No. 1 slider 175 is released, it will be pushed out by the No. 1 spring. When the No. 1 slider 175 is pushed out, it will push the circuit board to move so that the circuit board enters the storage box 20 for collection. When the No. 2 push plate 11 moves back to its original position, the pulling of the soft rope will be released. When the pulling of the soft rope is released, the threaded rod 171 will be driven by the accumulated force of the volute spring to rotate so that the sliding plate 174 returns to its original position. When the sliding plate 174 returns to its original position, the squeezing of the U-shaped plate 178 will be released, so that the U-shaped plate 178 is pushed back to its original position by the No. 2 spring. When the U-shaped plate 178 returns to its original position, it will push the vertical rod 177 to move. The vertical rod 177 The movement will push the latch rod 176 to move toward the No. 1 slider 175 and limit the latch rod 176. When the sliding plate 174 returns to its original position, it will contact the inclined surface below the No. 1 slider 175 and push the No. 1 slider 175 to move toward the inside of the No. 1 moving groove, so that the latch rod 176 limits the No. 1 slider 175. When the machine needs to be shut down, there is still a pressure rod circuit board remaining on the sliding plate 174. Press the gear shaft 173 to make the gear shaft 173 engage with the gear 172. Turn the handle to make the gear shaft 173 rotate and drive the gear 172 to rotate. When the gear 172 rotates, it will drive the threaded rod 171 to rotate. At this time, the remaining circuit board can be put into the storage box 20.

[0030] When the sliding plate 174 moves downward, it will contact the second slider 192, and the sliding plate 174 will push the second slider 192 to slide into the third moving groove. When the second slider 192 moves into the third moving groove, it will squeeze the third spring to store force. When the second slider 192 moves, it will drive the sliding groove to move. The movement of the sliding groove will squeeze the inclined rod 181 to slide away from the sliding groove. The sliding of the inclined rod 181 will push the sliding rod 184 to slide. The sliding of the sliding rod 184 will squeeze the elastic telescopic rod 188 to store force. When the slide bar 184 slides, it will contact the inclined surface of the inclined plate 183. When the slide bar 184 contacts the inclined surface of the inclined plate 183, it will push the inclined plate 183 to slide upward. When the inclined plate 183 slides upward, it will drive the square plate 182 to move upward to release the obstruction of the storage box 20 collecting the circuit board. When the slide bar 184 moves, it will drive the triangular rod 185 to move. When the triangular rod 185 moves, it will push the second rotating rod 187 to slide. When the second rotating rod 187 slides, it will drive the first rotating rod 186 to rotate. When the triangular rod 185 moves, it will drive the inclined rod 189 to move. When the sliding plate 174 returns to its original position, the squeezing of the second slider 192 is released, and the second slider 192 is pushed back to its original position by the third spring. When the second slider 192 returns to its original position, the contact with the slide bar 184 is released, and the slide bar 184 and the inclined rod 189 are elastically extended and retracted. When the rod 188 is pushed back to its original position, the inclined rod 189 returns to its original position to release the release from the fixed rod 190, and the fixed rod 190 returns to its original position due to its own gravity, disengages from the block 191, and releases the limit on the storage box 20. When the sliding rod 184 and the inclined rod 189 return to their original positions, they pull the triangular rod 185 to move. When the triangular rod 185 returns to its original position, it will drive the No. 1 rotating rod 186 and the No. 2 rotating rod 187 to return to their original positions, pushing the circuit board inside the storage box 20 into the storage slot for temporary fixed storage of the circuit board.
