The embodiment of the invention adopts at least one technical scheme which can achieve the following beneficial effects:
the first lifting and transverse moving component has the operation principle that two first motors are controlled to respectively drive a first lead screw and a second lead screw to rotate, when the first lead screw and the second lead screw rotate clockwise in the same direction, a driving gear is driven to move towards one side, when the first lead screw and the second lead screw rotate anticlockwise in the same direction, the driving gear is driven to move towards the other side, so that a third lead screw arranged below the driving gear is driven to transversely slide in a sliding opening at the bottom of a mounting box, so that the effect of transverse movement of a sucker is realized, when the first lead screw and the second lead screw rotate towards the opposite side simultaneously, the driving gear is driven to rotate, when the first lead screw and the second lead screw rotate towards the direction away from the opposite side simultaneously, the driving gear drives the third lead screw to rotate, so that a lifting outer rod rises or falls on the third lead screw, and a limiting inner rod and a matching outer rod are matched to ensure that the lifting outer rod slides up and down along a straight line, thereby realizing the effect of controlling the lifting of the sucking disc, the principle of the second lifting and transverse moving component is the same as that of the first lifting and transverse moving component, the first lifting and transverse moving component controls the sucking disc to contact with and adsorb the uppermost metal plate, the adjacent metal plates are sucked together in the process of controlling the metal plates to move upwards due to the action of negative pressure, a gap is generated between the edges of the two metal plates, the bottom end of the separating hook piece is controlled to be inserted into the gap between the two metal plates by the second lifting and transverse moving component, then the separating hook piece is controlled to move upwards for a small distance, the side end of the upper metal plate is slightly tilted, the gap between the two metal plates is gradually enlarged in the tilting process, air enters, the joint end of the two metal plates is relieved due to the action of the negative pressure generated by the sucking disc, so that the two metal plates are quickly separated, finally, the separating hook piece is controlled to move out from the two metal plates, the sucking disc is controlled to drive the metal plates to transversely move to a blanking area to complete blanking, thereby completing the sheet taking operation of the single metal plate.
Secondly, the separation hook piece and the sucking disc are the same and are all arranged at the bottom of the first lifting and horizontal moving assembly, the separation hook piece moves synchronously with the sucking disc when the sucking disc moves, the distance between the bottom of the separation hook piece and the adsorption end of the sucking disc is slightly larger than the thickness of a metal plate, so that when the sucking disc is contacted with the metal plate and sucks the metal plate, the bottom of the separation hook piece is aligned with the gap between the two metal plates, the second lifting and horizontal moving assembly is used for fine adjustment, compared with the method that the separation hook piece and the sucking disc are directly controlled to be aligned through the second lifting and horizontal moving assembly, the method that the distance between the separation hook piece and the sucking disc is set in advance is adopted, the time for adjusting the height of the separation hook piece is effectively reduced, the precision is higher, and the efficiency is improved.
Third, it is rotatory to control two second motor work and drive two fourth lead screws, thereby drive the plummer and place the stack metal sheet on the plummer and rise or descend, the setting of baffle can restrict the maximum rise height of stack metal sheet, compare in the driving piece that directly uses the cylinder class and so on and drive the plummer and go up and down, because the ascending distance of plummer at every turn is shorter, be the stroke of one or two metal sheet thickness usually, it is comparatively suitable to use its lift of fourth lead screw control, can set for the rotatory a week of fourth lead screw, the stroke of a metal sheet thickness of plummer rebound, compare in the use of cylinder, the lead screw drive is more accurate.
It is four, when stack metal sheet lifting to two metal sheets of the top are higher than the height of fixed plate, control electric putter output shrink and drive the sliding block rather than being connected and slide toward the fixing base direction on the slide bar, drive another sliding block simultaneously and slide toward the fixing base direction under the cooperation of two connecting rods, thereby drive the direction removal of two fixed plates toward the stack metal sheet, reach its fixed effect with the both sides of stack metal sheet respectively until two fixed plates, two metal sheets that are located the top are in the non-stationary state so that separate and get the piece.
And fifthly, the contact ends of the fixing plate and the separating hook sheet are made of soft rubber materials, so that the phenomenon that the separating hook sheet damages a coating on the surface of the metal plate when the fixing plate fixes the metal plate and the edge of the metal plate is tilted by the metal plate is avoided.
