The feeding mode options comprise a forward pushing vacuum button, a material taking X-axis forward pushing distance input frame, a material taking Y-axis side pushing distance input frame and a shaking frequency input frame. The material taking X-axis forward pushing distance input frame and the material taking Y-axis side pushing distance input frame can control the pushing direction and the pushing length of the mechanical gripper during material taking. The shaking times input box can be used for setting shaking times of the mechanical gripper during material taking. If the front pushing vacuum button is pressed, the material taking X-axis forward pushing distance and the material taking Y-axis side pushing distance need to be set; if the pre-push vacuum button is not pressed, the number of shakes needs to be set. Whether the push-to-vacuum button is pressed or not is judged by an operator. If the mechanical gripper shakes twice and still does not separate the plates, the vacuum degree between the plates is considered to be large, at the moment, the front pushing vacuum button is pressed, and the pushing distance is set, wherein the pushing distance is determined according to the length, the width and the like of the plates. The mechanical gripper pushes and is matched with the blocking device, so that the plates can be separated. If the mechanical gripper shakes twice or less to separate the plates, the vacuum degree between the plates is considered to be small, the vacuum button is not pushed before being pressed, and the shaking times of the mechanical gripper are set. Normally, the adsorption plate is selected to be pushed forwards or laterally for a set distance, so that the situation that the plate is shaken and not separated is avoided.

The parameter setting interface further comprises a material point deviation option and a set point deviation option. The material point deviation option comprises a material point X deviation input box and a material taking point Y direction deviation input box; the setpoint offset options include a setpoint X bias and a setpoint Y offset. And the material point deviation option are judged and input by an operator. The material point deviation option and the point placement deviation option can adjust the falling point of the mechanical gripper, and the stability of the mechanical gripper gripping plate is guaranteed.

When the photoelectric sensing device detects that an object exists on the lifting platform conveyor belt 21, a signal is transmitted to the operation platform, the operation platform sends an action instruction to the manipulator, and the manipulator acts; when the first photoelectric sensing device cannot detect the object, transmitting a signal to the operation table, sending an action instruction to the lifting table 2 by the operation table, lifting the lifting table conveyor belt 21 until the first photoelectric sensing device detects the object, and circularly reciprocating; if the lifting platform conveyor belt 21 still cannot detect the object beyond the set lifting height, the lifting platform conveyor belt 21 is indicated to have no plate, and the lifting platform conveyor belt 21 descends to be aligned with the ground conveyor belt 3 to charge the lifting platform conveyor belt 21. And (3) loading, namely, conveying the next batch of plates to the lifting platform 2 after the lifting platform 2 finishes conveying the previous batch of plates. The first photoelectric sensing device can also distinguish the base plate and the plate, if the first photoelectric sensing device senses the plate, information is sent to the operation table, and the operation table controls the mechanical gripper to convey the sensed plate to the processing conveying belt; if the photoelectric sensing device senses the base plate, information is sent to the operation table, and the operation table controls the mechanical gripper to convey the sensed base plate to the base plate stacking position.

In the descending process and the aligning process of the lifting platform conveyor belt 21, the lifting platform conveyor belt 21 firstly descends at a high speed, and when the lifting platform conveyor belt 21 is lower than the ground conveyor belt 3, the lifting platform 2 slowly ascends until the height of the lifting platform conveyor belt 21 is consistent with that of the ground conveyor belt 3. And a second photoelectric sensing device is arranged on the ground conveyor belt 3 and used for detecting the position of the conveyor belt in the aligning process, and the second photoelectric sensing device is electrically connected with the operating platform. After loading, the lifting platform 2 unloads, the lifting platform 2 descends at a fast speed in the unloading process, and after the uppermost plate is lower than the blocking roller 233, the lifting platform 2 slowly ascends until the uppermost plate is aligned with the blocking roller 233. The first photoelectric sensing device and the second photoelectric sensing device send sensing results to the operating platform, and the operating platform sends action instructions to the lifting platform 2 and the mechanical gripper 1. In the process of loading and unloading alignment, the lifting platform conveyor belt 21 is quickly lowered and slowly lifted after being lower than an alignment plane, so that the alignment is more accurate.

The operation panel also comprises an alarm information picture, and an operator can inquire the history of the abnormal record in the alarm information picture and know the running condition of equipment on the production line in time.

In this embodiment, when the sheets are stacked and conveyed in an overlapped manner, the sheets near the bottom of the stack are pressed by the sheets from above due to the smooth surface of the processed sheets, so that a vacuum environment is formed between the sheets, which causes two or more sheets to be adsorbed together. The mechanical gripper 1 may lift two or more panels if the mechanical gripper 1 only grips without further handling. However, in the process of processing the plate, each processing link is usually only suitable for the situation of a single plate. Therefore, in actual production, the mechanical gripper 1 can be manually arranged to shake or move towards the blocking roller according to the vacuum degree between the plates, and the plate adsorption condition is avoided.

The above, it is only the concrete embodiment of the utility model, and not right the utility model discloses make the restriction in any form, on not deviating from the technical scheme of the utility model basis, simple modification, the equivalent change or the modification made all fall into the protection scope of the utility model.
