As shown in fig. 1 to 3, the gripper 112 further includes a rotary cylinder 1121 installed on the fixing plate 1116 and a grabbing member 1122 fixed on the rotary cylinder 1121, and the height detection member 120 and the grabbing member 1122 are disposed at the same height, so as to ensure that the vertical distance detected by the height detection member 120 is the height of the gripper 112 required to move down.

Of course, other components such as suction cups and the like may be used for the gripping members 1122 depending on the material of the object 300 to be processed.

Referring to fig. 1 and 4, in an embodiment of the present invention, the controller calculates the walking distance of the horizontal movement of the gripper 112 according to the distance between the two opposite ends of the material rack 200 and the number of the objects 300 to be processed sequentially arranged between the two opposite ends of the material rack 200, so as to realize the one-by-one grabbing of the objects 300 to be processed. Specifically, the longitudinal direction of the material rack 200 is arranged along the x-axis, and a plurality of layers of the to-be-processed objects 300 are sequentially stacked in the height direction (the direction of the z-axis) of the material rack 200, and the to-be-processed objects 300 of each layer are sequentially and tightly arranged along the x-axis, so that after the controller obtains the length L of the material rack 200 and the number n of the to-be-processed objects 300 arranged in each layer, the walking distance of the gripper 112 moving along the x-axis direction is calculated according to the formula s ═ L/n, so as to grip each layer of the to-be-processed objects 300 one by one.

Of course, the walking distance traveled by the hand grip 112 in the x-axis direction may also be calculated in other ways. For example, in another embodiment, the to-be-processed objects 300 are regular round tubes or square tubes, the tube diameter of the round tubes or square tubes can be directly used as the walking distance of the gripper 112 moving along the x-axis, that is, the distance of each movement of the gripper 112 along the x-axis is equal to the tube diameter of the round tubes or square tubes, and thus, the to-be-processed objects 300 can be gripped one by one for each layer.

In the above manner, the controller may determine whether the loading of one layer of the object 300 to be processed is completed by counting the objects 300 to be processed or calculating the total distance of the movement of the gripper 112 along the x-axis direction. For example, in one mode, if the number of the to-be-processed objects 300 of each layer is n, when the gripper 112 starts to grip the first to-be-processed object 300 from one end of the material shelf 200, the controller starts to count the gripped to-be-processed objects 300, and when the recorded number is equal to n, it is indicated that the feeding of one layer of the to-be-processed objects 300 has been completed, and at this time, the controller controls the gripper 112 to move backward along the first guide 1111 to grip the to-be-processed objects 300 of the next layer one by one. In another mode, since the length L of the material shelf 200 is a fixed value, when the gripper 112 starts to grip the first object 300 to be processed from one end of the material shelf 200, the controller starts to cumulatively calculate the distance that the gripper 112 moves in the x-axis direction, and when the total distance that the gripper 112 moves in the x-axis direction is equal to L, it indicates that the gripper 112 has moved to the other end of the material shelf 200, and at this time, the controller controls the gripper 112 to move in the opposite direction along the first guide rail 1111 to grip the next object 300 to be processed one by one.

Further, in the above manner, the change of the vertical distance detected by the height detecting member 120 can be combined to more accurately determine whether the transportation of one layer of the object 300 to be processed is completed. Specifically, the controller compares the current vertical height detected each time with the vertical height detected last time, if the current vertical height is greater than the vertical height detected last time and the number of the objects to be processed 300 gripped by the gripper 112 is n, or the current vertical height is greater than the vertical height detected last time and the distance of the gripper 112 moving in the x-axis direction is equal to L, it indicates that the loading of one layer of the objects to be processed 300 has been completed, and at this time, the gripper 112 is controlled to move down to the current height to grip the objects to be processed 300 of the next layer, and the gripper 112 is controlled to move in the reverse direction along the first guide rail 1111 to grip the objects to be processed 300 of the next layer one by one.

With continued reference to fig. 1-2, when a plurality of material racks 200 are provided, the plurality of material racks 200 are sequentially arranged along the x-axis direction, and a distance D between two adjacent to-be-processed objects 300 between two adjacent material racks 200 is fixed, and the distance D is pre-recorded by a worker and stored in the controller, so that when all the to-be-processed objects 300 on one material rack 200 are completely loaded, the controller controls the gripper 112 to move along the first guide rail 1111 by the distance D to load the to-be-processed objects 300 in the next material rack 200.

The loading process and principle of the automatic loading device 100 of the present invention will be described with reference to fig. 1-4 again.

Before the work is started, firstly, a worker inputs the distance D between two adjacent material racks 200, inputs the length L of each material rack 200 and the number n of the to-be-processed objects 300 arranged on each layer, the controller respectively stores the data after acquiring the data, and then calculates and stores the walking distance of the gripper 112 moving along the x axis according to a formula s which is L/n; meanwhile, the distance between the machining station and the gripping position is acquired and stored as a preset distance, which is the distance that the gripper 112 moves along the y-axis.

Referring to fig. 1, before the automatic feeding device 100 starts feeding, an initial operation is performed, specifically, the controller controls the first slider 1114 to drive the second guide rail 1112 and the telescopic rod 1113 to slide along the first guide rail 1111 to an initial position, for example, to slide to one end of the first guide rail 1111 in a negative direction along the x-axis; then, the second slide block 1115 is controlled to drive the telescopic shaft 1113 to slide along the second guide rail 1112 by the preset distance to reach the grabbing position, for example, the telescopic shaft 1113 slides along the y-axis forward by the preset distance, and the preset distance is preset according to the length of the object 300 to be processed and the distance between the object 300 to be processed and the processing station, so long as the telescopic shaft 1113 can slide above the object 300 to be processed and be convenient for grabbing.

Then, the second slide block 1115 is controlled to drive the telescopic shaft 1113 to slide to the grabbing position again along the positive direction of the y axis, and then the first slide block 1114 is controlled to slide on the first guide rail 1111 for a walking distance s along the positive direction of the x axis, that is, the gripper 112 is driven to slide to a position corresponding to the next object 300 to be processed; at this time, the negative sliding height h of the telescopic shaft 1113 along the z axis is controlled again, so that the gripper 112 moves down to the designated height again, the electromagnet is controlled to be powered on to suck the object 300 to be processed, then the rotary cylinder 1121 is controlled again to act to drive the gripper 112 to rotate by the preset angle, then the second slider 1115 is controlled to drive the telescopic shaft 1113 to slide by the preset distance along the negative direction of the y axis, at this time, the gripper 112 reaches the processing station, and then the electromagnet is controlled to be powered off to release the object 300 to be processed to the processing station.

The above steps are repeated until the number of the to-be-processed objects 300 recorded by the controller is n, and the vertical distance h detected by the height detecting member 120 changes, specifically, when the current vertical distance is greater than the previously detected vertical distance, it is determined that the feeding of one layer of the to-be-processed objects 300 is completed, at this time, the telescopic shaft 1113 is controlled to slide in the negative direction along the z axis, so that the gripper 112 continuously moves down to the current height to grip the next layer of the to-be-processed objects 300, and when the feeding of the to-be-processed objects 300 is completed and the gripping position on the second guide rail 1112 is returned, the walking distance s of the first slider 1114 sliding in the negative direction along the x axis is controlled again, so that the gripper 112 grips the next to-be-processed. The process is circulated until the loading of the layer of the object 300 to be processed is completed.

After finishing the loading of all the objects 300 to be processed in one material rack 200, the controller controls the first slider 1114 to slide on the first guide rail 1111 in the forward direction along the x-axis for a sliding distance D, so that the gripper 112 slides to a position corresponding to the object 300 to be processed at the end of the next material rack 200, and then controls the gripper 112 to repeat the above steps to finish the gripping of the object 300 to be processed in the material rack 200.

The structures, arrangement modes, etc. of other parts of the automatic feeding device 100 related to the present invention are conventional designs in the field, and detailed description is not provided herein.

In summary, in the automatic feeding device 100 of the present invention, the end of the three-axis sliding table manipulator 110 is provided with the gripper 112 and the height detection piece 120 located at the same height, so that the height of the gripper 112 to the object 300 to be processed can be detected by the height detection piece 120, the gripper 112 is controlled by the controller to move down by a corresponding height to grip the object 300 to be processed, then the controller calculates the walking distance of the horizontal movement of the gripper 112 according to the preset mode, and controls the sliding mechanism 111 to move to drive the gripper 112 to move horizontally by the walking distance, and then moves down to grip another object 300 to be processed, so as to circularly realize the full-automatic feeding of the object 300 to be processed, thereby improving the feeding efficiency and further improving the overall processing efficiency of the whole production line.
