Then, the air blowing device supplies air to the suction cup, so that the uppermost mask is sucked by the suction cup 21 by utilizing the principle that the air flow in the concave portion of the suction cup is fast and has low pressure, the air flow on the mask side is slow and has high pressure, at this time, as the rotating shaft 58 continues to rotate or rotate reversely, the contact position of the roller 580 and the side surface of the driving plate 590 is switched to the protrusion 5902 on the other side from the concave portion 5902, and then the lifting rod 560 is gradually lifted, so that the first workpiece grabbing assembly 1, the second workpiece grabbing assembly 2 and the third workpiece grabbing assembly 3 of the adsorption mask are moved upwards.
S3, when the first motor 51 is started, the rotating disc 57 is driven to rotate at the same time, when the rotating disc 57 rotates, the rotating shaft 56 moves in the annular guide groove 571, due to the shape limitation of the annular guide groove 57, when the rotating shaft 56 is located in the small semicircular arc section of the annular guide groove 571, the rotating shaft 56 does not rotate along with the rotation of the annular guide groove 571, when the rotating shaft 56 is located in the convex driving arc section of the annular guide groove 571, the rotating shaft 56 is driven to move along with the movement of the driving arc section, the movement of the rotating shaft 56 drives the pushing rod 55 to rotate around the shaft 510, so that the front end of the pushing rod 55 extends forward and retreats, and further drives the supporting column 53 connected with the pushing rod to extend forward and retreat. When the slide rail is lifted, the push rod 55 does not rotate around the shaft 510 connected thereto, and when the lifting rod 560 is lifted to the maximum height, the push rod 55 rotates around the shaft 510, and the moving mechanism 5 drives the first workpiece grabbing assembly 1, the second workpiece grabbing assembly 2, and the third workpiece grabbing assembly 3 to extend forward.
At the same time or later, the push-pull device 44 of the variable pitch adjustment mechanism 4 is started to push the shaft sleeve 43 connected therewith to slide along the guide rail 42 to the outer end, so as to push the distance between the second workpiece grabbing component 2 connected with the shaft sleeve 43 and the first workpiece grabbing component 1 to be increased, and at the same time, the shaft sleeve 43 at one end drives the first linkage rod 47 in driving connection to deform (i.e. the included angle between the first and second linkage rods is reduced), and the deformation of the transmission rod 46 in an X shape drives the second linkage rod 48 to deform, so as to drive the shaft sleeve 43 at the other end to move in the direction away from the support 41, at this time, the first workpiece grabbing component 1, the second workpiece grabbing component 2 and the third workpiece grabbing component 3 are switched to the second state (opening state) and respectively correspond to one material receiving device, and at this time, blanking.
And S4, driving the slide rail 520 to descend by a second motor of the moving mechanism 5 so as to drive the first workpiece grabbing assembly 1, the second workpiece grabbing assembly 2 and the third workpiece grabbing assembly 3 to move downwards, stopping supplying air to the suction cup by the air supply device after the second motor of the moving mechanism 5 moves to the lowest position, stopping adsorbing by the suction cup, enabling the mask on the suction cup to fall onto the material receiving device, and driving the first workpiece grabbing assembly 1, the second workpiece grabbing assembly 2 and the third workpiece grabbing assembly 3 to reset by the moving mechanism 5 so as to take materials again.
The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
