When the material carrier plate passes in the reverse direction, the block three directly blocks the material carrier plate due to that the side of the block three without cutting. When reverse passing is needed, the small cylinder three lifts the heavier end of the block three, the raised end will drop, so that the material carrier plate can pass in the reverse direction. The proximity switch five is mounted on the block three, and is used for sensing the position of the block three to determine the current working state of the block three.

[0034] When the material carrier plate is in the positioning and lifting module, the positioning platform is in the uppermost layer, the material carrier plate is in the middle layer, and the lifting platform is in the lowermost layer. When the material carrier plate needs to leave the transportation system and be taken away by other equipment, in order to place the material carrier plate on the positioning platform, the positioning platform first needs to perform an opening action, that is, the lifting platform lifts the material carrier plate to the upper layer to leave space, then the lifting platform rises from the gap between the power roller three and the electric roller three to lift the material carrier plate to a height higher than the positioning pin one, and then the positioning platform performs a closing action to place the material carrier plate on the positioning platform.

[0077] When the material carrier 4 is in the positioning lifting module 3, the positioning platform 3-12 is in the uppermost layer, the material carrier 4 is in the middle layer, and the lowermost layer is the lifting platform 3-13. When the material carrier 4 needs to leave the transportation system and be taken away by other equipment, in order to place the material carrier 4 on the positioning platform 3-12, the positioning platform 3-12 first needs to perform an opening action, the lifting platform 3-13 lifts the material carrier 4 to the upper layer to leave space, then the lifting platform 3-13 rises from the gap between the power roller three 3-7 and the electric roller three 3-8, lifts the material carrier 4 to a height higher than the positioning pin one 3-12-3, and then the positioning platform 3-12 performs a closing action to place the material carrier 4 on the positioning platform 3-12. When the material carrier 4 needs to be put into the positioning lifting module 3, the movement sequence of each part is opposite to that of sending out. The positioning platform 3-12 performs opening and closing actions through two rodless cylinders 3-11, and the lifting platform 3-13 performs lifting action through the lifting cylinder 3-14.

[0078] The working process of the high-precision positioning double-layer conveying circulating line provided by the application is as follows:

[0079] Before the material carrier 4 is transferred to the positioning lifting module 3 by the external equipment, the rodless cylinder 3-11 moves the positioning platform 3-12 from the open state to the closed state. The external equipment places the material carrier 4 on the positioning platform 3-12 and positions it through the positioning pin one 3-12-3, then the lifting platform 3-13 is lifted by the lifting cylinder 3-14, the positioning pin two 3-13-1 of the lifting platform 3-13 is inserted into the material carrier 4 and lifted to a height higher than the positioning pin one 3-12-3, and then the positioning platform 3-12 is restored to the open state by the rodless cylinder 3-11. The lifting platform 3-13 is lowered, and the material carrier 4 is placed on the power roller three 3-7 and the electric roller three 3-8, and the positioning pin two 3-13-1 is disengaged.

[0080] When the material carrier 4 is ready to exit the lifting platform three 3-6, the small cylinder three 3-9-3 first lifts the block three 3-9-2, and then the electric roller three 3-8 rolls to send the material carrier 4 out of the lifting platform three 3-6 and directly into the double-layer roller module 2. When the proximity switch four 3-10 detects that the material carrier 4 is completely out, the small cylinder three 3-9-3 retracts, and the block three 3-9 resets.

[0081] After the material carrier 4 enters the double-layer roller module 2, it is transported to the other end by the power roller two 2-4, and can be stopped by the blocker 2-5 during the transportation to perform other operations.

[0082] When the material carrier 4 enters the lifting platform one 1-6, the block one 1-9 is pressed down by gravity, and the electric roller one 1-8 carries the material carrier 4 into the lifting platform one 1-6. After the material carrier 4 passes, the block one 1-9 is tilted up by gravity to block. When the proximity switch one 1-10 detects that the material carrier 4 is completely in, the cylinder one 1-2 performs the lifting action to carry the material carrier 4 into the next layer.

[0083] When the material carrier 4 is ready to exit the lifting platform one 1-6, the small cylinder one 1-9-3 first lifts the block one 1-9-2, and then the electric roller one 1-8 sends the material carrier 4 out of the lifting platform one 1-6. When the proximity switch one 1-10 detects that the material carrier 4 is completely out, the small cylinder one 1-9-3 retracts, and the block one 1-9 resets.

[0084] After the material carrier 4 enters the double-layer roller module 2, it is transported to the other end by the power roller two 2-4, and can be stopped by the blocker 2-5 during the transportation to perform other operations.

[0085] When the material carrier 4 enters the lifting platform three 3-6, the block three 3-9 is pressed down by gravity, and the electric roller three 3-8 carries the material carrier 4 into the lifting platform three 3-6. After the material carrier 4 passes, the block three 3-9 is tilted up by gravity to block. When the proximity switch four 3-10 detects that the material carrier 4 is completely in, the cylinder three 3-2 performs the lifting action. After the cylinder three 3-2 completes the lifting action, the lifting platform 3-13 is lifted by the lifting cylinder 3-14, the positioning pin two 3-13-1 of the lifting platform 3-13 is inserted into the material carrier 4 and is lifted to a height exceeding the positioning pin one 3-12-3 (in order to position the platform 3-12 to move smoothly), the rodless cylinder 3-11 moves the positioning platform 3-12 to the designated position, and then the lifting platform 3-13 is lowered to make the positioning pin one 3-12-3 inserted into the material carrier 4, and then the positioning pin two 3-13-1 is disengaged, the lifting platform 3-13 returns to the lowest point, and after the material carrier 4 is taken away by the external equipment, the positioning platform 3-12 returns to the initial position.
