working state: during normal operation

After the workpieces are stacked on the tray 102, stacking the tray 102 together and then sending the workpieces to the first conveyor belt 6, wherein a lifting table 4 in a feeding frame 2 is in a descending state, a movable plate 402 on the lifting table 4 is rotationally lifted to form an inclined angle under the action of a lifting rod 403, in the lifting table 4, the rotation axis of the movable plate 402 is positioned at one side far away from the first conveyor belt 6, so that one side of the movable plate 402, close to the first conveyor belt 6, is higher, and the height of the movable plate is consistent with the height of a roller 8 at the tail end of the first conveyor belt 6, at the moment, the first conveyor belt 6 starts to convey the stacked tray 102 on the roller 8 of the first conveyor belt 6, the roller 8 of the first conveyor belt 6 is obliquely arranged downwards, the tray 102 moves obliquely downwards under the action of gravity and then passes through an auxiliary rotary drum 9 at one side of the lifting table 4, which is close to the first conveyor belt 6, and then moves onto the movable plate 402, and the tray 102 continuously moves due to the inclined movable plate 402; the limiting walls 401 are arranged on one side, far away from the first conveyor belt 6, of the lifting table I4 and one side, far away from the blanking device, of the two limiting walls 401 form a right angle, two rows of rollers 8 are obliquely arranged on the movable plate 402, the sliding direction of the tray 102 can be decomposed into the front side and the side face, the tray 102 can slide laterally until the side faces of the two sides of the tray 102 are contacted with the corresponding side limiting walls 401, the tray 102 stops sliding until the lifting table I4 starts to rise to a set position and stops, in the rising process, the lifting rod 403 is fixed, the movable plate 402 can recover to a horizontal state in the process, at the moment, one side, close to the first conveyor belt 6, of the tray 102 descends along with the tray 102, after the movable plate 402 recovers to the horizontal state, the top end of the auxiliary rotary drum 9 on the lifting table I4 is higher than the bottom surface of the bottom-layer tray 102, at the moment, the auxiliary rotary drum 9 serves as a limit, and the tray 102 is prevented from shaking and falling in the rising process.

When the uppermost tray 102 in the feeding frame 2 is completely taken out by the manipulator, the empty tray 102 needs to be transported into the discharging frame 3, the transportation track 103 starts to operate, the clamping plate 105 in the feeding frame 2 stretches out to hold the tray 102, the clamping plate 105 is provided with a telescopic range, when the clamping plate stretches out, the tray 102 is only held and cannot be clamped, the clamping plate 105 holds the tray 102, the lifting table 4 descends to separate the lower tray 102 from the uppermost tray 102, then the power push plate 106 moves towards the direction of the discharging frame 3, in the process, the power push plate 106 contacts the upright post on the tray 102, and the tray 102 is driven to move by pushing the upright post on the tray 102, so that the tray 102 is pushed into the discharging frame 3 from the feeding frame 2. If the tray 102 of the feeding rack 2 only remains the last and needs to be transported to the discharging rack 3, the lifting platform one 4 is lifted to enable the bottom surface of the tray 102 to be flush with the surface of the track 103, at this time, the clamping plate 105 keeps a contracted state, if the clamping plate stretches out to interfere with the limiting wall 401 on the lifting platform one 4, when the lifting platform one 4 is lifted to a set position, the protruding block in the discharging rack 3 can press the limiting movable block 406 on the lifting platform one 4 downwards, so that the top surface of the limiting movable block 406 is lower than the bottom surface of the tray 102, and then the power push plate 106 moves again to push the tray 102 into the discharging rack 3.

The blanking frame 3 is used for sending machined workpieces to the next procedure, if the equipment runs for the first time, an empty tray 102 can be placed on the first conveyor belt 6, then the tray 102 is automatically sent into the blanking frame 3 through the upper frame 2 and the transfer rail 103, in the transfer process of the tray 102, the tray 102 can be pushed onto the clamping plate 105 in the blanking frame 3 through the rail 103 in the transfer rail 103, when the tray 102 is sent to a required position, the tray 102 can contact the limiting plate 104 in the blanking frame 3, the power push plate 106 also stops moving at the moment and then returns to the upper frame 2, after the tray 102 is sent to the blanking frame 3, the lifting table two 5 in the blanking frame 3 is lifted, at the moment, the clamping plate 105 in the blanking frame 2 is kept in a contracted state, when the lifting table two 5 is lifted to a set position, the lug in the upper frame 2 can press the limiting movable block 406 on the lifting table two 5, the tray 102 is ensured to be smoothly moved, the lifting table two 5 is lifted to the working table 1 in sequence, and then the machine is lifted to the working table 1; in this process, if the uppermost tray 102 in the blanking frame 3 is not fully stacked with workpieces, but when the workpieces in the uppermost tray 102 in the upper frame 2 are already taken, the power pushing plate 106 pushes the empty tray 102 into the track 103 of the transfer track 103, after the uppermost tray 102 in the blanking frame 3 is fully stacked, the lifting table two 5 descends again, then the clamping plate 105 in the blanking frame 3 stretches out, the power pushing plate 106 pushes the tray 102 onto the clamping plate 105 in the blanking frame 3 again, then the power pushing plate 106 resets, the lifting table two 5 ascends in the process to enable the lower tray 102 to prop against the upper tray 102, then the clamping plate 105 contracts, and the manipulator continues to start stacking the workpieces.

When the stacked trays 102 in the blanking frame 3 reach the set number and all the workpieces are full, the blanking frame 3 starts to perform blanking, the lifting table II 5 descends to the set position, the lifting rod 403 on the lifting table II 5 contacts the movable plate 402 and jacks up the movable plate 402, the convex strips 502 on the movable plate 402 rotate in the jacking process of the movable plate 402, the auxiliary rotary drum 9 originally jacked up by the convex strips 502 falls down to the bottom under the action of gravity and the springs 405, at the moment, the top ends of the auxiliary rotary drum 9 and the top ends of the rotary drums 8 of the movable plate 402 are in the same plane, the tray 102 slides to the conveyor belt II 7 under the action of gravity and the rotary drums 8 on the inclined movable plate 402, the tray 102 passes through the auxiliary rotary drum 9 in the process, the rotary drums 8 on the conveyor belt II 7, and then reaches the conveyor belt II 7 to convey the auxiliary rotary drum to the next process, and blanking between the processing is completed.

Embodiment two:

working state: when the supply speed of the work piece is insufficient

When the supply speed of the machined parts is insufficient or the required machining amount is small, a tray 102 which is fully stacked with the machined parts can be directly prevented from being arranged on the first conveyor belt 6, and then the working procedures of feeding, machining and discharging are sequentially started; compared with the normal working state, the lifting table needs to be lifted frequently in the working state, the movable plate 402 needs to be lifted frequently, the working load of the rubber roller 404 on the lifting rod 403 is also relatively large, the cleaning of the bottom of the movable plate 402 is noted, and whether the rubber roller 404 is damaged or stuck with foreign matters is checked regularly, so that the normal production is prevented from being influenced. Correspondingly, if the requirement of the working procedure after blanking on the workpieces is not urgent, the working mode of the blanking frame 3 can be selected under normal working, the trays 102 are stacked to a set number and then sent out for blanking, the stacked trays 102 occupy a relatively small conveying belt, if a certain number of workpieces to be processed are stacked in the rear working section, and the stacked trays 102 are easy to put and arrange.
