[0013] As the cam rotates, the lifting frame descends under the action of gravity, and the computer motherboard falls back onto the side transmission belt. When the side transmission belt transports the computer motherboard to the top of the docking frame, the side transmission belt stops moving again.

Then the computer motherboard slides along the slope of the discharging push plate to the discharging slope, and finally leaves the device. When the computer motherboard observed by the camera on the bending frame is broken, this computer motherboard reaches the bottom of the detection board and is detected. The discharging electric cylinder will also push out the broken computer motherboard.

[0015] As the rear transmission wheel rotates, the lower cam is driven to rotate, and the lower cam rotates to push the rotating plate to rotate around the frame body.

[0038] As the cam 207 rotates, the lifting frame 209 descends under the action of gravity, and the computer motherboard 4 falls back onto the side transmission belt 105. When the side transmission belt 105 transports the computer motherboard 4 to the top of the docking frame 220, the side transmission belt 105 stops moving again, and the rotation of the eccentric gear 213 drives the active rotating rod 215 to rotate through the eccentric column 214, thereby driving the slider 230 to slide in the slide groove 217, thereby driving the short rotating rod 216 to rotate, thereby driving the lifting block 219 to slide under the docking frame 220.

At this time, the discharge electric cylinder 225 is started, and the discharge electric cylinder 225 quickly extends to drive the discharge push plate 226 to extend.

The inner transmission belt 106 and the side transmission belt 105 transport the computer motherboard 4, and the computer motherboard 4 is centered through the guide plate 107. The side transmission belt 105 drives the rear transmission wheel 108 and the output gear 109 to rotate at the same time. The rotation of the cam 207 drives the lifting frame 209 to rise and fall, and the lifting frame 209 and the docking column 210 rise. At this time, the computer motherboard 4 is just transported to the top of the lifting frame 209 by the side transmission belt 105, and the side transmission belt 105 just stops moving at this time. The lifting frame 209 contacts the computer motherboard 4 through the inner arc surface of the guide block, so that the hole position of the computer motherboard 4 can be aligned with the docking column 210, and the docking column 210 is inserted into the hole of the computer motherboard 4. The lifting frame 209 drives the computer motherboard 4 to rise, so that the computer motherboard 4 contacts the top block 204. After the contact, the lifting frame 209 continues to rise for a short distance, and a small amount of additional pressure is applied to the computer motherboard 4. The computer motherboard 4 is observed by the camera on the bending frame 203. The computer motherboard 4 may be slightly bent within the allowable range. If the computer motherboard 4 is broken, it is unqualified.As the cam 207 rotates, the lifting frame 209 descends under the action of gravity, and the computer motherboard 4 falls back onto the side transmission belt 105. When the side transmission belt 105 transports the computer motherboard 4 to the top of the docking frame 220, the side transmission belt 105 stops moving again, and the rotation of the eccentric gear 213 drives the active rotating rod 215 to rotate through the eccentric column 214, thereby driving the slider 230 to slide in the slide groove 217, thereby driving the short rotating rod 216 to rotate, thereby driving the lifting block 219 to slide under the docking frame 220. The rotation of the rotating rod 218 around the frame 101 realizes the lifting and lowering of the docking frame 220 and the insertion column 221 along the frame 101. The docking frame 220 contacts the computer mainboard 4 through the inner arc surface of the guide block, so that the hole position of the computer mainboard 4 can be aligned with the insertion column 221. The contact insertion column 221 is inserted into the hole of the computer mainboard 4. The computer mainboard 4 is driven to rise by the docking frame 220. The components on the computer mainboard 4 are respectively matched with the component inspection slots on the lower surface of the detection board 222. The components on the computer motherboard 4 are fully inspected. If unqualified components are found, the corresponding indicator light 223 lights up. When the docking frame 220 descends, the computer motherboard 4 falls back onto the side transmission belt 105. At this time, the docking frame 220 continues to descend. At this time, the discharge electric cylinder 225 is started, and the discharge electric cylinder 225 quickly extends to drive the discharge push plate 226 to extend. The slope on the upper surface of the discharge push plate 226 forks the computer motherboard 4, so that the computer motherboard 4 leaves the side transmission belt 105, and then the computer motherboard 4 moves along the discharge push plate 226. The slope of plate 226 slides onto the discharge slope 224 and finally leaves the device. When the camera on the bending frame 203 observes that the computer main board 4 is broken, after the computer main board 4 reaches the bottom of the detection plate 222 and is detected, the discharge electric cylinder 225 will also push out the broken computer main board 4. If the computer main board 4 passes the inspection, the discharge electric cylinder 225 will not move, and the computer main board 4 will fall onto the side transmission belt 105. When the side transmission belt 105 continues to rotate, the computer main board 4 will be transported to the rotating plate 302. As the rear transmission wheel 108 rotates, the lower cam 303 is driven to rotate, and the lower cam 303 rotates to push the rotating plate 302 to rotate around the frame 101, and the computer motherboard 4 slowly slides from the rotating plate 302 to the delivery slope 301. At the same time, the output gear 109 rotates to drive the side gear 304 to rotate, thereby driving the side gear shaft 305 and the side bevel gear 306 to rotate, thereby driving the docking bevel gear 308, the docking shaft 307 and the active belt gear 309 to rotate, thereby driving the transmission belt 311 to move. The transmission belt 311 drives the bag rack 312 forward a distance each time. When the bag rack 312 completes the position change, the computer motherboard 4 slides along the delivery slope 301 into the packaging bag 313.

[0042] That is, when the outer gear 104 is out of mesh with the half-toothed gear 229, the side transmission belt 105, the inner transmission belt 106, and the lower cam 303 do not move, and the computer motherboard 4 is located below the bending frame 203 or below the detection plate 222 or on the rotating plate 302. At this time, the lifting frame 209 and the docking frame 220 complete a lifting; when the outer gear 104 is engaged with the half-toothed gear 229, the side transmission belt 105, the inner transmission belt 106, and the lower cam 303 move, and the side transmission belt 105 and the inner transmission belt 106 transport the computer motherboard 4 that has just been placed to the bottom of the bending frame 203, and the side transmission belt Belt 105 transports the computer motherboard 4 originally located under the bending frame 203 to under the inspection plate 222, and transports the qualified computer motherboard 4 originally located under the inspection plate 222 to the rotating plate 302. The rotating plate 302 completes one lifting and falling, and sends the computer motherboard 4 originally located on the rotating plate 302 to the delivery slope 301. The transmission belt 311 rotates once to move the next packaging bag 313 to the front of the delivery slope 301. After the transmission belt 311 completes the rotation, the computer motherboard 4 slides along the delivery slope 301 into the packaging bag 313.
