Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding, in particular to a plate out-of-warehouse picker. Background Art

[0002] Currently, a suction-cup robot is typically used to remove sheets from the material warehouse and feed the CNC turret punch press. However, thin sheets can cause adhesion when stacked together, meaning the suction-cup robot can pick up multiple sheets at once. The lower sheets can either fall during transport, scratching equipment lines, or enter the machine along with the top sheet. The thickened sheets can inevitably damage the mold, making existing suction-cup robots prone to causing production safety accidents when picking up sheets. Utility Model Content

[0003] The purpose of the utility model is to address the deficiencies in the prior art and to provide a plate out-of-warehouse picker that can avoid production safety accidents caused by plate feeding.

[0004] In order to achieve the above purpose, the technical solution adopted by the plate outbound picker of the utility model is:

[0005] A plate outbound picker comprises a frame having a plurality of first suction cups, a side edge of the frame being provided with a lifting mechanism, the lifting mechanism comprising a rotating shaft pivotally connected to the frame, the frame being provided with a driving device for driving the rotating shaft to rotate, the outer circumference of the rotating shaft being provided with a plurality of second suction cups arranged in a straight line, and the outer circumference of the rotating shaft or the edge of the frame being provided with a plate thickness measuring mechanism. The first and second suction cups simultaneously suck up plates in the material warehouse, and then the driving device drives the rotating shaft to rotate, which drives the second suction cups to rotate, and the plurality of second suction cups drive the edges of the plates to be outbound to flip upward, thereby creating gaps between the plates and eliminating the phenomenon of adhesion between the plates due to oil film or vacuum negative pressure, that is, separating the sucked plates. Finally, the plate thickness measuring mechanism is used to inspect the separation effect of the lifting mechanism to ensure that the plates outbound are single sheets.

[0006] Preferably, the plate thickness measuring mechanism includes a first cylinder installed on a rotating shaft or a frame, the telescopic rod of the first cylinder is fixedly connected to a first vertical plate, the first vertical plate is fixedly connected to a second cylinder, the telescopic rod of the second cylinder faces downward and is fixedly connected to a first clamping plate, the side wall of the first clamping plate is provided with a second vertical plate, the second vertical plate is fixedly connected to a third cylinder, the telescopic rod of the third cylinder faces downward and is fixedly connected to the second clamping plate, the first and second clamping plates cooperate to clamp the plate to be shipped out of the warehouse, the top surface of the second clamping plate is installed with a fourth cylinder, the telescopic rod of the fourth cylinder faces upward and is fixedly connected to a sensor bracket, and the sensor bracket is installed with a thickness measuring sensor.

[0007] Preferably, a first bracket for mounting the second suction cup and a second bracket for mounting the first cylinder are fixedly connected to the outer side of the rotating shaft.

[0008] Preferably, the driving device includes a servo motor, the output shaft of the servo motor is fixedly connected to a reducer, the reducer is fixedly connected to the frame, and the reducer is connected to the rotating shaft through a coupling.

[0009] Preferably, the first and second suction cups are pneumatic suction cups.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The first and second suction cups simultaneously absorb the plates in the material warehouse, and then the driving device drives the rotating shaft to rotate, which drives the second suction cup to rotate. Multiple second suction cups drive the edges of the plates to be shipped out to flip upward, so that gaps are generated between the plates, eliminating the phenomenon of adhesion between the plates due to oil film or vacuum negative pressure, that is, the absorbed plates are separated. Finally, the plate thickness measuring mechanism is used to inspect the separation effect of the edge lifting mechanism to ensure that the plates shipped out are single sheets, thereby avoiding production safety accidents caused by plate feeding.

DETAILED DESCRIPTION

[0017] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0018] like Figure 1-4As shown, a plate outbound picker includes a frame 2 with multiple first suction cups 1, the first suction cups are evenly arranged on the frame, and a lifting mechanism 3 is installed on the left edge of the frame. The lifting mechanism includes a rotating shaft 31 pivoted to the frame, and the frame is installed with a driving device 32 for driving the rotating shaft to rotate. The driving device includes a servo motor 321, and the output shaft of the servo motor is fixedly connected to a reducer 322. The reducer is fixed to the frame, and the reducer is connected to the rotating shaft through a coupling 323. The servo motor can set different lifting angles according to plates of different specifications. Five second suction cups 33 arranged in a straight line are arranged on the outer circumference of the rotating shaft. The first and second suction cups are both pneumatic suction cups. The second suction cup is fixed to the rotating shaft through a first bracket 311. The outer circumference of the rotating shaft is installed with a plate The material thickness measuring mechanism 4 includes a first cylinder 41, which is fixed to the rotating shaft through the second bracket 312, and the telescopic rod of the first cylinder is fixed to the first vertical plate 42, and the first vertical plate is fixed to the second cylinder 43, and the telescopic rod of the second cylinder is downward and fixed to the first clamping plate 44, and the side wall of the first clamping plate is fixed to the second vertical plate 441, and the second vertical plate is fixed to the third cylinder 45, and the telescopic rod of the third cylinder is downward and fixed to the second clamping plate 46, and the first and second clamping plates cooperate to clamp the plate to be shipped out, and the area of ​​the second clamping plate is larger than that of the first clamping plate, and the excess part is used to install the fourth cylinder 47, and the fourth cylinder is installed on the top surface of the second clamping plate, and the telescopic rod of the fourth cylinder is upward and fixed to the sensor bracket 48, and the sensor bracket is installed with a thickness measuring sensor 49.

[0019] It should be noted that the plate thickness measuring mechanism proposed in the present invention can also be installed on the edge of the frame through different brackets, and is also used to detect the thickness of the plates to be shipped out.

[0020] The specific working process and principle of a plate out-of-warehouse picker are as follows: the frame descends, the first and second suction cups fall down and suck the plate 5 at the same time, the frame ascends to an appropriate position (corresponding to between the first and second clamping plates), the motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the second suction cup to rotate, and the second suction cup drives the edge of the plate to flip upward. If the sucked plate has adhesion, the edge of the top plate will flip over and create a gap with the plate below. The plate below will fall off by itself under the action of its gravity, thereby achieving sheet separation. The motor drives the rotating shaft to reset again, allowing the plate to return to a horizontal state, start the first cylinder, and the telescopic rod of the first cylinder retracts, so that the first clamping plate is above the plate and the second clamping plate is below the plate. At the same time, the second and third cylinders are started to drive the first and second clamping plates to cooperate in clamping the plate, and then the fourth cylinder is started to drive the thickness sensor to measure the thickness of the plate. If the measured thickness is the thickness of a single plate, it can be shipped out of the warehouse. If the measured thickness exceeds the thickness of a single plate, the plate will continue to be separated by the edge lifting mechanism until the measurement result is the thickness of a single plate. When the utility model takes materials, the sheets are first separated by the edge-lifting mechanism, and then the sheet thickness measuring mechanism is used to check the separation effect of the edge-lifting mechanism, so as to ensure that the sheets shipped out of the warehouse are single sheets, thereby avoiding production safety accidents caused by sheet feeding and greatly improving safety and reliability.
