Two groups of second supporting electric push rods e8 for supporting the clamping frame are symmetrically arranged on the stacking racks e1 on both sides of the depressurization stacking area e3;

[0119] The two side walls of the clamp frame are provided with lifting support plates cooperating with the first lifting plate e51 and the second lifting plate e71.

[0120] The working principle of this utility model:

[0121] When the clamp frame is not in use and pressure is not maintained, the threaded ejector rod and ejector rod sleeve of the pressure-maintaining clamping assembly are located on the top inclined surface of the pressure-maintaining support ejector block;

[0122] When in use, the pencil board is fed through the feeding conveyor, and the corresponding driving motor of the driving assembly drives the corresponding driving gear to rotate. Since the driving gear is meshed with the corresponding guide rack, the x-direction moving plate, the y-direction moving plate and the z-direction lifting rod can be driven along the corresponding directions to realize the three-way movement of the clamping claw assembly. The clamping claw assembly is driven to move by the driving assembly, and the two clamping hydraulic cylinders of the frame clamping claw assembly drive the frame clamping claw to clamp the empty bundle clamp frame in the depressurization zone, and then the bundle clamp frame is placed on the pressurization zone of the workbench, and the frame clamping claw is released;

[0123] The clamp frame is placed on the pressurized area of the workbench, and the frame is limited and fixed by the table clamping assembly. The driving assembly drives the clamping claw assembly to move to the pencil board feeding and conveying device, and the double-headed cylinder of the pencil board clamping claw assembly drives two pencil board clamps to grab the pencil board. Then the clamping claw assembly moves to the position of the clamp frame in the pressurized area, and the pencil board clamps are released and grabbed by the double-headed cylinder, and the pencil board is placed on the clamp frame, so that the pencil board fills the clamp frame;

[0124] Afterwards, the moving table driving motor under the pressurizing area drives the moving table under the pressurizing area to move back and forth on the lower base at the pressurizing area to the corresponding position to be pressurized, and then the pressurizing top plate is driven by the pressurizing hydraulic cylinder to push the pressure-keeping top plate to move in the direction of the clamp frame, and the pressure-keeping clamping connecting rod moves in the direction of the pencil board accordingly, driving the pressure-keeping clamping plate to move in the direction of the pencil board to clamp the pencil board. At this time, since the push rod sleeve is rotatably connected to the rotating support seat, the threaded push rod and the push rod sleeve slowly leave the top of the pressure-keeping supporting top block as the pressure-keeping clamping plate moves, and then slides down with the inclined surface, and stops when the threaded push rod slides down to the pressure-keeping limit block. The pressure-keeping limit block supports the bottom of the threaded push rod, and the pressure-keeping support top block supports one end of the threaded push rod, and the pressure-keeping clamping plate is kept stationary to continuously clamp and pressurize the pencil board. At this time, the pressurizing hydraulic cylinder can retract the pressurizing top plate to stop pressurizing;

[0125] Afterwards, release the table clamping assembly to release the limit fixation on the frame body, and drive the clamping claw assembly through the driving assembly to grab the pressure-maintaining clamp frame, and then place it on the pressure-maintaining stacking area of the clamp frame circulation stacking device on the side of the pressurizing area, and extend the push rods through the two groups of first supporting electric push rods to support the four corners of the clamp frame. The pressurized clamp frames are stacked on top in sequence. After stacking more, the first lifting cylinder drives the first lifting plate to rise to support the lifting support plates on the two side walls of the lowest clamp frame, and first drives the stacked lifting plates to move down the distance of a clamp frame, and then supports the second clamp frame through the first supporting electric push rod. The first lifting cylinder drives the clamping frame to move down to the clamping frame conveyor belt, and then the clamping frame conveyor belt drives the clamping frame to move to the depressurization stacking area. The lifting support plate of the clamping frame is located on the second lifting plate, and the clamping frame is driven by the second lifting cylinder to move up to the second supporting electric push rod, and supported by the first supporting electric push rod. The second lifting cylinder descends and repeats the above operation. During the stacking process, the pencil board can be pressure-maintained without the need for the pressurized hydraulic cylinder to continuously apply pressure to the clamping frame, which saves space for the equipment, frees up the clamping frame and the pressurized hydraulic cylinder, and can move the clamping frame when pressure is maintained, facilitating subsequent operations.

[0126] When decompression is required after the pressure holding is completed, the driving assembly drives the clamping claw assembly to grab the topmost clamp frame in the decompression stacking area, place the clamp frame in the decompression area, and then clamp and fix the frame through the table clamping assembly. Then, the moving table under the decompression area is moved to the corresponding position where decompression is required. The buffer cylinder first drives the buffer top plate to support the pressure holding top plate. At this time, the decompression cylinder drives the corresponding decompression ejector rod through the table decompression ejector rod through-hole and the frame decompression ejector rod through-hole in turn to eject the threaded ejector rod out of the top of the pressure holding support top block. Then, the buffer cylinder drives the buffer top plate to slowly retreat, and the buffer top During the retraction of the plate, the decompression cylinder drives the decompression ejector rod to retract. At this time, the pressure-holding clamping plate loses its support. Due to the effect of the return spring on the pressure-holding clamping connecting rod between the pressure-holding top plate and the outer wall of the frame, the pressure-holding clamping plate gradually moves away from the pencil plate to achieve clamping and decompression. The buffer cylinder and the buffer ejector plate can play a buffering role during decompression, and support the pressure-holding top plate during decompression. A certain gap is generated between the threaded ejector rod and the supporting ejector block, which facilitates the decompression ejector rod to eject the threaded ejector rod to ensure the decompression effect and efficiency. By avoiding the sudden rebound of the return spring, the return spring is better protected and the service life of the return spring is increased.

[0127] After that, the clamped and pressure-maintained pencil board is grasped by the gripper assembly, and the pencil board is placed on the discharging conveying device and output through the discharging conveying device. Then, the clamping and fixing of the frame by the table clamping assembly is released, the beam clamping frame is grasped by the gripper assembly, and the beam clamping frame is placed on the pressurizing area. Repeating the above operations forms an automatic beam clamping and pressure-maintaining production line for pencil boards, which can reduce the usage amount of beam clamping frames. The circulating assembly line improves the production efficiency, saves the factory space, has a high degree of automation, and is more convenient and fast to operate. During this period, if there are too many beam clamping frames, the descending beam clamping frames can be transported to the warehouse by an AGV cart for stacking and pressure-maintaining in sequence, and then the beam clamping frames are transported to the pressure-relieving stacking area by the AGV cart, lifted to the top by the second lifting cylinder, and grasped by the gripper assembly to the pressure-relieving area for pressure relief, thus forming a cycle as well.
