Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.
The present invention is described in detail below with reference to the drawings and the specific embodiments, which are not repeated herein, but the embodiments of the present invention are not limited to the following embodiments.
As shown in fig. 1, according to an embodiment of the present invention, the automatic sheet feeding and discharging apparatus includes an automatic feeding mechanism 1, a sheet separating mechanism 2, and a sheet gripping mechanism 3.
In this embodiment, the automatic feeding mechanism 1 includes a sealed box 11, a discharge hole is opened on the sealed box 11, and a feeding assembly 12 is arranged inside the sealed box 11 and used for feeding sheets. Specifically, according to one mode of the present invention, the feeding assembly 12 of the present invention includes a motor screw 121 located below the discharge port and a screw slider 122 cooperatively connected with the motor screw 121. In actual production, a plurality of laminated sheets are placed on the screw slider 122, and when the motor screw 121 rotates in operation, the screw slider 122 can be moved in the vertical direction, so that the sheets can be moved towards the discharge port of the sealed box 11.
In the invention, as the sheets are conveyed by the matching of the motor screw 121 and the screw slider 122 and are all positioned in the sealed box body 11, namely, the sealed box body 11 is completely sealed except the discharge port, the sheets can be ensured not to float and dust accumulation phenomenon can not occur in the feeding process.
As shown in fig. 1, the sheet separating mechanism 2 of the present invention includes a protecting cover 21 disposed at the discharge port of the sealed box 11, and the protecting cover 21 is connected to a ventilation pipeline 22. In this embodiment, the protective sleeve 21 is a ring structure, and the protective sleeve 21 is disposed on the periphery of the discharge port of the sealed box 11 to perform the protection and dust prevention functions. In actual production, the sheet operated by the motor screw 121 is lifted out of the discharging position and enters the annular cavity of the protective sleeve 21, and then the sheet grabbing mechanism 3 enters the protective sleeve 21 to suck the sheet. Since the sheet thickness is thin, electrostatic adhesion is likely to occur, and a plurality of sheets may be adsorbed at one time. At this time, since the middle vent pipe 22 is connected to the protective cover 21, air can be blown into the protective cover 21 through the vent pipe 22 to separate the adhered sheets, so that one sheet is adsorbed at a time for subsequent operations.
The automatic loading and unloading device for the thin slices can ensure that one thin slice is loaded each time due to the arrangement of the vent pipeline 22. Simultaneously, because the mode of the separation thin slice of ventilating that adopts compares in prior art and adopts modes such as baffle to separate the thin slice, this scheme is non-contact separation thin slice, when separating the thin slice, also can avoid causing deformation fold influence to the thin slice.
As shown in fig. 1, the automatic sheet feeding and discharging device of the present invention further includes a correlation sensor 13 at a discharge port of the sealed box 11. After the sheets are sucked and taken away, the correlation sensor 13 can sense that the thickness of the stacked sheets is reduced, drive the screw slider 122 to move upwards by the thickness of one sheet, and drive the screw slider 122 to reset downwards and prompt the feeding again when no material is sensed.
As shown in fig. 1, the sheet gripping mechanism 3 of the present invention includes a movable slide table 31 and a two-way suction head 32 connected to the movable slide table 31, and the two-way suction head 32 includes a gas passage 321 fixed to the movable slide table 31 and a suction nozzle 322 installed in communication with the gas passage 321 at a front end thereof. The gas passage 321 is communicated with a negative pressure gas source 33, and the gas passage 321 is also communicated with a separation gas source 34. Wherein the negative pressure air source 33 is used for providing negative pressure adsorption force to enable the suction nozzle 322 to suck up the slice. When the suction nozzle 322 sucks the sheet and moves to the mounting position for blanking, the negative pressure air source 33 needs to be closed to let the sheet fall to the mounting position, however, in actual production, the sheet is often adhered to the suction nozzle 322 to cause the failure of blanking. The separating air source 34 is used for ventilating air to the direction of the suction nozzle 322 through the air passage 321 when the sheet is adhered to the suction nozzle 322, so that the sheet is separated from the suction nozzle 322 and the whole sheet is discharged.
The working force flow of the automatic sheet loading and unloading device is as follows:
the motor screw 121 works, so that the screw slider 122 drives the sheet to move upwards to the discharge hole, the suction nozzle 322 moves downwards to the protective sleeve 21 to adsorb the sheet, then the protective sleeve 21 is blown through the ventilation pipeline 22 arranged on the protective sleeve 21, the adhered sheet is blown down, the suction nozzle 322 adsorbs one sheet at a time, then the suction nozzle 322 moves to the blanking position together with the sheet, the negative pressure air source 33 is closed, the separation air source 34 is opened, and the sheet is accurately blanked to the mounting position.
The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
