DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] An intelligent bending device for plates, such as Figure 1-8 As shown, it includes a workbench 1, a bending machine 2 is slidably installed on the top surface of the workbench 1, and a first motor 5 is installed at one end of the workbench 1, and the output end of the first motor 5 is connected to a first screw rod 6 that cooperates with the bending machine 2. The first motor 5 can drive the bending machine 2 to and fro between the loading and unloading positions through the first screw rod 6. Both ends of the first screw rod 6 are connected to ratchet gears 13, and both ends of the workbench 1 are rotatably connected to large gears 14, and chains 15 are sleeved on the ratchet gears 13 and the large gears 14. When the first screw rod 6 rotates forward or reversely, it can drive a large gear 14 to rotate through a ratchet gear 13 and a chain 15, and the other ends of the rotating shafts of the two large gears 14 are respectively connected to the two threaded sleeves 7. There are mutually meshing bevel gears 18 connected in between, a partition 3 is arranged in the middle of the workbench 1, and the top surface of the workbench 1 is located at both ends of the partition 3 and is rotatably connected with a threaded sleeve 7, and the interior of each threaded sleeve 7 is threadedly connected with a threaded column 8, and the top surfaces of the two threaded columns 8 are respectively connected to a loading plate 9 and a unloading plate 10. When the large gear 14 rotates, it can drive the corresponding bevel gear 18 to rotate, thereby driving the corresponding threaded sleeve 7 to rotate, controlling the loading plate 9 to rise or the unloading plate 10 to fall, one side of the large gear 14 is connected with a ratchet 16, and both ends of the workbench 1 are provided with a pawl 17 cooperating with the ratchet 16, and the ratchet 16 and the pawl 17 cooperate to prevent the large gear 14 from reversing.

[0038] Furthermore, a bracket 19 cooperating with the rotating shaft of the large gear 14 is provided on the top surface of the workbench 1, so that the large gear 14 can drive the bevel gear 18 to rotate more stably.

[0039] See also Figure 2 A set of first slide rails 4 cooperating with the bending machine 2 is arranged on the top surface of the workbench 1 to limit the movement of the bending machine 2.

[0040] See also Figure 2 and Figure 5 A sliding plate 11 is slidably connected between the partition 3 and the top surface of the workbench 1 above the loading plate 9, and a plurality of vacuum suction cups 12 are arranged on the sliding plate 11. The sliding plate 11 can drive the plate 30 to be loaded by adsorbing the plate 30 through the vacuum suction cups 12, and the partition 3 and the top surface of the workbench 1 are both provided with a second slide rail 25 that cooperates with the sliding plate 11 to limit the movement of the sliding plate 11.

[0041] See also Figure 1 and Figure 5 A second motor 26 is installed on the front side of the partition 3 , and an output end of the second motor 26 is connected to a second screw rod 27 that cooperates with the sliding plate 11 . The second motor 26 can mobilize the sliding plate 11 to move through the second screw rod 27 .

[0042] The first motor 5 and the second motor 26 are both servo motors.

[0043] See also Figure 1 , Figure 6 and Figure 7 A plurality of first cylinders 20 are installed on the top surface of the bending machine 2, and the output ends of the first cylinders 20 are rotatably connected to the unloading push plates 21. The first cylinders 20 can push the bent sheet 30 to be unloaded through the unloading push plates 21. The unloading push plates 21 are each provided with a plurality of vacuum suction cups 12, which can adsorb the sheet 30 to prevent the sheet 30 from falling off when it is not in place.

[0044] See also Figure 6 A set of fixing screws 22 cooperating with the material unloading push plate 21 are rotatably connected to the output end of the first cylinder 20, so as to fix the material unloading push plate 21 at any angle.

[0045] See also Figure 1 , Figure 2 and Figure 7 The front of the unloading plate 10 is rotatably connected to a rotating plate 23, and both ends of the unloading plate 10 are rotatably installed with a second cylinder 24 whose output ends are rotatably connected to the two ends of the rotating plate 23 respectively. The second cylinder 24 can drive the rotating plate 23 to rotate to adapt to the bending angle of the plate 30 to prevent the plate 30 from tipping over due to the center of gravity when unloading and stacking.

[0046] The connection between the second cylinder 24 and the blanking plate 10 is located at the bottom of the blanking plate 10, and the connection between the second cylinder 24 and the rotating plate 23 is located at the top of the rotating plate 23, so that when the rotating plate 23 is horizontal, the second cylinder 24 pulls the rotating plate 23 to rotate.

[0047] In order to further improve the stability of the lifting and lowering of the loading plate 9 and the lowering plate 10 , a plurality of telescopic guide rods 29 are connected between the top surface of the workbench 1 and the loading plate 9 and the lowering plate 10 .

[0048] See also Figure 1 The top surface of the workbench 1 is located on the back of the loading plate 9 and is connected to a baffle 28 that cooperates with the loading plate 9, which can limit the position of the plate 30 when stacking, so that the length of the plate 30 extending into the bending machine 2 is more accurate.

[0049] When in use, the plates 30 are stacked and placed on the loading plate 9. At this time, the bottom surface of the top plate 30 is slightly higher than the working surface of the bending machine 2. Then, the rotation angle of the bending plate of the bending machine 2 is set to control the bending angle of the plate 30. Then, the unloading push plate 21 and the rotating plate 23 are adjusted to the same angle. The unloading push plate 21 is rotated to the same angle, which can better fit the inclined surface of the plate 30 after the bending is completed, which is convenient for the adsorption of the vacuum suction cup 12. The rotating plate 23 is rotated to the same angle. When the bending point is located in the middle of the plate 30, the bending surface of the plate 30 is supported to prevent it from being bent due to the original center of gravity. Due to the tipping, the moving distance of the sliding plate 11 is set to determine the length of the sheet 20 inserted into the bending machine 2 to control the bending position, and then the device can be started. First, the air pressure in the vacuum system is reduced, and a pressure difference is generated between the air pressure in the vacuum suction cup 12 and the external atmospheric pressure, so that the vacuum suction cup 12 and the topmost sheet 30 are tightly combined together. When the vacuum degree in the vacuum system reaches the working air pressure of the vacuum suction cup 12, the second motor 26 is started to drive the sliding plate 11 and the vacuum suction cup 12 to move, drive the sheet 30 to insert into the bending machine 2, and then stop vacuuming, and input air into the vacuum system. The difference between the air pressure in the system and the external atmospheric pressure decreases until it is equal to or slightly higher than the atmospheric pressure. The sheet 30 is separated from the vacuum suction cup 12 due to its own weight, and the second motor 26 reverses to drive the sliding plate 11 to reset. The pressing plate of the bending machine 2 descends to clamp the sheet 30, and then the bending plate of the bending machine 2 rotates to a preset angle to bend the sheet 30. Then the first motor 5 starts to drive the first screw rod 6 to rotate, and the bending machine 2 is moved to the unloading position. At the same time, the first screw rod 6 drives the ratchet gear 13 near the unloading position to rotate, and drives the matching large gear 14 to rotate through the chain 15, that is, The bevel gear 18 and the threaded sleeve 7 can be used to drive the blanking plate 10 to drop just the thickness of a plate 30, the pressure plate of the bending machine 2 rises to release the plate 30, the second cylinder 24 pushes the blanking push plate 21 to contact the inclined surface of the plate 30, the vacuum suction cup 12 can adsorb the plate 30, and then push the plate 30 onto the blanking plate 10, then the vacuum suction cup 12 is separated from the plate 30, the second cylinder 24 is reset, the first motor 5 is reversed to drive the bending machine 2 to reset, and at the same time drives the ratchet gear 13 near the loading position to rotate, so that the loading plate 9 rises the thickness of a plate 30, and one cycle can be completed.
