[0020] In order to be able to drive and return the cutting workbench 51 in the laser processing material area 5 to the laser cutting machine 8, the cutting workbench 51 is driven by an electric conveyor belt transversely arranged in the laser processing material area 5; in order to ensure that the cutting workbench 51 enters the laser cutting machine 8 along the designated position, and at the same time has a certain supporting force through the laser cutting machine, and does not hinder the collection of waste or dust during laser cutting, the cutting workbench 51 corresponds to one end of the laser cutting machine 8, and its two sides are slidably matched with the guide grooves symmetrically arranged on both sides of the laser cutting machine 8, and the other end is fixed on the electric conveyor belt.

[0021] In order to ensure that the loading and unloading robot below the moving beam 74 has excellent stability when the moving beam 74 runs at high speed, the Z rods 72 are provided with two Z rods 72, which are arranged horizontally and in parallel on the moving beam 74, and the loading and unloading robot 73 at the bottom thereof is composed of a plurality of loading and unloading suction cups controlled by cylinders.

[0022] In order to ensure that the loading and unloading robot 73 does not damage the equipment by causing the plate at the bottom of the loading and unloading suction cup to fall due to power failure during its movement, a fork is provided directly below the loading and unloading suction cup. The fork can move forward and backward through a cylinder and is connected to the loading and unloading suction cup at the bottom of the Z rod 72 through an integrated board. The loading and unloading robot 73 moves to the specified position and then descends. At the same time, the fork opens and closes after it is lower than the bottom surface of the plate, and the fork catches the plate. At the same time, the loading and unloading suction cup sucks the plate, and the Z rod 72 is moved above and moves to the designated area for unloading through the moving beam 74.

[0023] In order to be able to flexibly cut the plate on the cutting table 51 in the laser cutting machine 8 according to program requirements, the laser cutting machine 8 includes a Y-axis 81 for connecting the Z-axis and a waste trough 82 arranged below the Y-axis.

X-axes 83 for mounting the Y-axis 81 are symmetrically arranged on the front and rear sides of the top of the waste trough 82. The Y-axis 81 slides with the X-axis 83.

[0024] In order to enable the moving beam 74 to move on the upper guide rail 71, the moving beam 74 is slidably connected to the upper guide rail 71 via a slider, and a servo motor is fixedly provided on the moving beam 74, and a driving gear is connected to the servo motor, and the driving gear is meshed with a rack provided on one side of the upper guide rail 71 at the top of the frame 7. The moving beam 74 rolls on the rack through the driving gear driven by the servo motor to realize its forward and backward movement.

[0025] Its specific working method is as follows: first, the storage of thick raw materials. The operator places the plates on the support frame 11 of the three-dimensional plate material warehouse 1 by forklift or crane, and needs to align with the positioning pins set on the support frame 11, and then the lift 2 sends the support frame 11 stacked with plates into the layered storage position specified by the three-dimensional plate material warehouse 1. The operator controls the entry and exit of the plates on the operating table that is intelligently controlled by the three-dimensional plate material warehouse 1. After the plates are put into the warehouse, the plate information of the current storage position is manually entered into the system interface of the operating table of the three-dimensional plate material warehouse 1 to ensure that the three-dimensional plate material warehouse 1 contains the plates required for the production schedule; when the plates need to be shipped out for processing, the lift 2 enters a designated layer of the three-dimensional plate material warehouse 1 according to the plate demand issued by the laser cutting machine 8, takes out the whole stack of plates through the fork frame 21, descends to the discharge layer, and moves the whole stack of plates to the front discharge trolley 4 through the fork frame 21, and places them on the front discharge trolley 4, the front discharge trolley 4 detects that the plate is in place and moves to the side of the laser processing material area 5 through the lower guide rail; then the loading and unloading robot 73 moves to the top of the front discharge trolley 4 through the moving beam 74, opens the fork teeth and suction cup to grab the plate, and the front discharge trolley 4 is provided with magnet layering, blowing, thickness measurement and other functions. After the suction cup is controlled by the cylinder to suck the plate, the plate thickness is measured, which can eliminate the problem of multi-layer suction. After the grabbing is completed, the loading and unloading robot 73 moves the plate to the top of the laser processing material area 5 through the moving beam 74, and places the plate on the cutting table 51, and then the loading and unloading robot 73 moves to a safe position, and the cutting table 51 is sent into the laser cutting machine 8 through the conveyor belt, and the Y axis 81 moving on the X axis 83 in the laser cutting machine 8 and the Z axis moving on the Y axis 81 control the laser cutting head to cut the plate, and the laser cutting machine starts to work; after the laser cutting machine 8 completes the cutting, The cutting table 51 is returned to the laser processing material area 5 via the conveyor belt, and then the loading and unloading robot 73 moves to the top of the cutting table 51, opens the fork teeth to the cutting table 51, uses the fork teeth to pick up the cut plates, and sends the cut plates to the roller sorting table 6. The roller sorting table 6 moves the cut plates to the outside for manual sorting.

[0026] When the laser cutting machine 8 needs to replace different plates for processing, the elevator 2 places the plates of the original discharge layer in the empty space of the three-dimensional plate warehouse 1, and according to the processing demand information, takes out the plates required by the laser cutting machine 8 from the corresponding warehouse and transports them to the discharge layer.

[0027] When it is necessary to feed the shearing machine, the raw materials required by the shearing machine are manually input into the raw material specifications on the operating table of the three-dimensional plate material warehouse 1. After completion, the elevator 2 takes out the plates in the designated warehouse, and after descending to the discharge layer, it is moved to the top of the shearing machine electric trolley 3 through the fork frame 21 and placed on the shearing machine electric trolley 3. Then the shearing machine electric trolley 3 transports the plates to the side of the shearing machine, and the number of plates used is manually calculated. When the laser cutting machine 8 is working, the shearing machine electric trolley 3 is not between the three-dimensional plate material warehouse 1 and the front discharge trolley 4, so as not to affect the operation of the front discharge trolley 4.

[0028] This thick plate material laser cutting production line can realize the integrated assembly line laser cutting processing of thick plate materials from stacking, material selection, unloading to cutting. It has high processing efficiency, less manual intervention, reduced costs, and improved the safety of the production environment. It is suitable for the automated cutting processing of various thick plate parts and is easy to promote and popularize.
