[0054] Here’s how it works:

[0055] like Figure 2 and Figure 3 As shown, when the board sending unit 1 is working, the staff stacks the boards to be sent on the product loading platform 1-6, and the first horizontal moving module 1-13 on the first truss 1-5 drives the first vertical moving module 1-12 to move on the horizontal moving track 1-4, and stops moving when it moves above the product loading platform 1-6; the first vertical moving module 1-12 moves downward on the vertical moving track 1-1, and stops moving after moving to a certain distance, and the grabbing suction cup 1-10 absorbs the board, and the first horizontal moving module 1-13 drives the first vertical moving module 1-12 and the board to move above the conveyor belt 1-6 and the grabbing suction cup 1-10 places the board on the conveyor belt 1-6; the first horizontal moving module 1-13 cooperates with the first vertical moving module 1-12 to fill the four board placement points on the first conveyor belt 1-7 in turn.

[0056] The transport motion module 1-11 moves to the product waiting area 1-8 on the first conveyor belt 1-7, drives the transport suction cup 1-9 to adsorb the plate and move it above the feed roller 4, and the transport suction cup 1-9 places the plate on the feed roller 4, and the feed roller 4 transports the plate to the next work section.

[0057] like Figure 4 and Figure 5As shown, when the stacking unit 2 is working, the staff will neatly stack the four-inch plates and the six-inch plates on the second product discharge table 2-3 and the first product discharge table 2-2 respectively, and the second horizontal moving module 2-9 drives the second vertical moving module 2-10 to move on the beam 2-11, move to the top of the first product discharge table 2-2, stop moving, and the second vertical moving module 2-10 moves downward and drives the grabbing suction cup 8 to adsorb and grab the six-inch plate. After moving upward to a certain distance, it moves to the top of the product stacking table 2-1 driven by the second horizontal moving module 2-9, and places the six-inch plate on the product stacking table 2-1. The first product positioning module 2-13 performs the positioning work of the six-inch plate. When the new six-inch plate is stacked on the neatly stacked plates on the product stacking table 2-1, the first product positioning module 2-13 pushes the stacked plates to accurately adjust the stacked plates to be neat and consistent.

[0058] At the same time, the second horizontal moving module 2-9 drives the vertical moving module 2-9 to move on the beam 2-9 to the top of the second product unloading platform 2-3, stops moving, and the second vertical moving module 2-10 moves downward and drives the grabbing suction cup 2-7 to absorb and grab the four-inch plate. After moving upward to a certain distance, it moves to the top of the product positioning platform 2-4 driven by the second horizontal moving module 2-9, and places the four-inch plate on the product positioning platform 2-4.

After the positioning is completed, the product stacking movement module 2-5 transports the positioned four-inch plate to the product stacking platform 2-1. When the four-inch plate and the six-inch plate are accumulated and stacked into three pieces, the second conveyor belt 2-12 moves to the side of the feed roller 4, and the stacked product handling module 2-6 grabs and transports the four-inch plate and the six-inch plate to stack them on the plate transmitted by the board sending unit 1 on the feed roller 4. After the stacking is completed, the feed roller 4 continues to transport them to the next section.

[0059] like Figure 6 and Figure 7As shown, when the multilayer board unit 3 is working, the staff will stack the boards required for production and place them on the board feeding table 3-8, and the horizontal reciprocating displacement module 3-4 on the support frame 3-7 will drive the linear up and down motion module 3-1 to move on the horizontal reciprocating track 3-5, and stop moving when it moves above the board feeding table 3-8; the linear up and down motion module 3-1 moves downward on the linear up and down motion track 3-2, and stops moving after moving to a certain distance, and the suction cup 3-12 absorbs the board, and the horizontal reciprocating displacement module 3-4 drives the linear up and down motion module 3-1 and the board to move to the belt conveyor The conveying mechanism 3-9 is above the suction cup 3-12 to place the plate onto the belt conveyor mechanism 3-9, and the belt conveyor mechanism 3-9 transfers the plate to the multi-layer plate stacking and collecting table 3-10 in turn. After the multi-layer plate stacking and collecting table 3-10 collects the stacked quantitative plates, it stops collecting, and the transfer module 3-13 moves to above the multi-layer plate stacking and collecting table 3-10, clamps the multi-layer stacked plates through the transfer clamp 3-11 and moves to above the feed roller 4, and the transfer clamp 11 places the multi-layer plate on the plate transported by the stacking unit 2 on the feed roller 4, and the feed roller 4 transports the plate to the next work section.

[0060] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
