A plurality of alignment claws f62 are rotatably connected to the alignment pivot f61. One end of an alignment return spring f63 is connected to the upper end of the alignment claws f62. The other end of the alignment return spring f63 is connected to the top of the gantry frame f4 through a spring fixing rod f64. A limit rod f65 is connected to the top of the gantry frame f4 above the alignment claws f62.

[0086] The unloading assembly f5 includes an unloading cylinder f51 mounted on the gantry f4, and an unloading pressure block f52 is fixedly connected downward to the output end of the unloading cylinder f51.

[0087] The unloading sensor f8 is a photoelectric sensor.

[0088] The feeding assembly b is equipped with a photoelectric sensor to determine the quality of the pencil board.

[0089] The working principle of this utility model:

[0090] When the pressure holding is not in use and the pencil board is not clamped, the pressure holding push rod of the pressure holding assembly is far away from the clamping plate, and the locking block of the pressure holding locking assembly is not engaged in the one-way slot of the pressure holding push rod;

[0091] In use, the robot arm picks up the empty clamping frames from the rear clamping frame stacking seat and places them on the worktable. The frame is initially limited by the frame limiting baffle and frame limiting block. Then, the frame fixing cylinder of the frame fixing component drives the frame fixing pressure block to move forward to limit and clamp the frame of the clamping frame. The pencil board is fed through the feeding component. The photoelectric sensor in the feeding component detects the quality of the pencil board. The poor board is placed on the poor board collection component by the robot arm, and the good board is picked up by the robot arm and placed on the clamping frame.

[0092] The pencil board is placed between the two guide rods, the clamping plate, and the end of the frame furthest from the pressure-holding assembly. Then, the hydraulic cylinder of the pressure-applying assembly moves the pressure block towards the frame, causing the pressure sleeve at the front of the pressure block to move accordingly. Passing through the pressure sleeve's through-hole in the frame, the clamping plate moves towards the pencil board for initial clamping. The forward movement of the pressure block moves the release support block and the release block (the release cylinder has a neutral solenoid valve that allows the cylinder rod to move even when not in operation). As the pressure block moves, it pushes the pressure-holding top rod of the pressure-holding assembly towards the clamping plate. Once in position, the fixing bolt of the pressure-holding locking assembly, through the action of the second spring, engages with the corresponding one-way slot on the pressure-holding top rod. The hydraulic cylinder can then retract, moving the pressure block and pressure sleeve away from the frame. When the frame stops pressurizing, the unidirectional slots formed between the unidirectional conical steps, combined with the locking blocks of the fixing bolts, ensure that the pressure-holding top rod moves in one direction without rebounding. Even when the pressure block leaves, the pressure-holding top rod can still hold the clamping plate, ensuring the clamping and pressure holding of the pencil board. This eliminates the need for continuous pressure from the hydraulic cylinder to maintain pressure on the pencil board, saving space in the clamping frame. The clamping frame can be moved during pressure holding for convenient subsequent operations. Afterward, the clamping of the frame is released, and the frame position is moved by the robotic arm. The above operation is repeated to clamp and hold the pencil board in other positions within the frame. Then, the clamping frame is removed by the robotic arm and placed on the empty clamping frame stacking seat at the rear for pressure holding. The clamping frames after pressure holding are stacked sequentially on the clamping frame stacking seat.

[0093] When the pressure holding is completed and the clamping needs to be released, the clamping frame that needs to be released after pressure holding is placed back on the worktable by the robot arm. The frame is then clamped and limited. The clamping cylinders of the first and second plate-removing clamping components drive the corresponding clamping rods through the frame and clamping plate to clamp the pencil board. This ensures that the pencil board will not move after subsequent pressure release, making it convenient for the robot arm to pick up and transfer the pencil board. Then, the pressure release cylinder of the pressure release component drives the pressure release support block and pressure release block to move towards the pressure holding top rod. The tapered through groove of the pressure release block cooperates with the inclined surface of the long side of the fixing bolt to press down on the long side end of the fixing bolt. The short side of the fixing bolt will move away from the slot of the pressure holding top rod, releasing the locking of the pressure holding top rod. At this time, the setting of the first return spring will make the pressure holding top rod move away from the clamping plate, releasing the pressure holding clamping of the pencil board. Then, the robot arm will take away the pencil board.

[0094] The depressurized pencil boards are placed on the receiving platform by a robotic arm, where unloading conveyor components are placed sequentially. After a certain number are placed, the motor of the unloading conveyor component, together with gears and racks, drives the pusher plate to move the stacked pencil boards toward the alignment component. The alignment claws of the alignment component level the pencil boards. Then, the unloading sensor detects the pencil boards and the unloading cylinder drives the unloading block to move down, pushing the pencils onto the discharge conveyor, which then transports them to the subsequent processes.
