In a preferred embodiment, a pair of vertically disposed balustrades 35 is disposed on the right side of the vertical frame 31, and the balustrades 35 are symmetrically disposed with respect to a vertical center line of the vertical frame 31; the upper end and the lower end of the handrail 35 are respectively provided with a fourth cylinder 351 which is arranged on the vertical rack 31, and the fourth cylinder 351 drives the handrail 35 to move along the front-back direction of the vertical rack 31; the end points of the travel of the balustrade 35 relative to the sheet on the exit plate frame 2 are respectively located within and outside the width of the sheet. This setting is used for realizing the prepositioning of panel to ensure that the panel on the grillage 2 of going out is at the preliminary location alignment of vertical direction, ensure simultaneously that panel provides sufficient area of contact for the conveyer belt. Specifically, the working mode is as follows:

(1) the third cylinder 321 drives the rail 35 to move oppositely to the width range of the plate, and a blocking mechanism is provided for the plate on the plate outlet frame 2 through the rail 35;

(2) the plate on the plate outlet frame 2 is horizontally moved leftwards until the plate abuts against the railing 35, so that the plate on the plate outlet frame 2 is ensured to be preliminarily positioned and aligned in the vertical direction;

Considering that when the trimming knife group 43 of the edge trimmer 4 trims the burrs on the peripheral edges of the plates, a large amount of dust generated by the cutting burrs is attached to the surfaces of the plates, and the dust generated by the cutting burrs is attached to the surfaces of the plates and falls off naturally, and also comprises the electrostatic adsorption of the plates, and the dust attached to the surfaces of the plates due to the dust is difficult to be cleaned thoroughly by the brushes, and even more static electricity is accumulated on the plates due to the action of the brushes, so that the cleaning becomes more difficult. On the other hand, a first ion wind rod 45 is disposed on the upper side and a second ion wind rod 46 is disposed on the lower side of the inner edge of the discharge port 42 of the edge trimmer 4, and the air outlet surfaces of the first ion wind rod 45 and the second ion wind rod 46 face the inside of the edge trimmer 4 with respect to the plate material flowing direction. The first ion wind bar 45 and the second ion wind bar 46 blow a large amount of air masses with positive and negative charges into the edge trimmer 4, and static electricity on both the front and back surfaces of the area where the plate is still located inside the edge trimmer 4 is neutralized, so that the electrostatic adsorption capacity of the plate itself is eliminated. Therefore, the dust generated in the trimming process cannot be adsorbed on the plate by static electricity, so that the dust attached to the surface of the plate can be more thoroughly cleaned by adopting the hairbrush in the prior art.

Moreover, since the first and second turning arms 55 and 56 cooperate to turn the plate on both sides, the first and second ion wind bars 45 and 46 eliminate the electrostatic adsorption capability of the plate, and therefore, even though there are dust left on the plate after the brush cleaning, the dust can be shaken off during the plate turning process.

In a preferred embodiment, the first flipping arm 55 has a flipping stroke greater than 90 degrees, the second flipping arm 56 has a flipping stroke less than 90 degrees, and the sum of the flipping stroke of the first flipping arm 55 and the flipping stroke of the second flipping arm 56 is less than 180 degrees. Taking the example that the turning stroke of the first turning arm 55 is 92 degrees and the turning stroke of the first turning arm 55 is 80 degrees, this arrangement can ensure that the first turning arm 55 turns up the sheet material to a state in which the sheet material can be turned over, and also can ensure that the second turning arm 56 can turn up and receive the turned sheet material, thereby preventing the sheet material from being subjected to excessive impact.

In the preferred embodiment, the piston rod of the first cylinder 551 extends obliquely upwards and is hinged at the lower edge of the first tilting arm 55, and the cylinder body of the first cylinder 551 is pivotally connected to the horizontal frame 51 with its axis of rotation parallel to the first pivot 53; the piston rod of the second cylinder 561 extends obliquely upwards and is hinged to the lower edge of the second tilting arm 56, and the cylinder body of the second cylinder 561 is also pivotally connected to the horizontal frame 51, the pivot axis of which is parallel to the second pivot 54.

In a preferred embodiment, the third conveyor belt 52 is a belt conveyor mechanism with a conveying direction consistent with the plate material flowing direction, and includes a belt supporting plate 521 with a length direction parallel to the plate material flowing direction, a pair of belt guide rollers 522 separately disposed at two ends of the belt supporting plate 521, and a conveyor belt 523 stretched over the belt guide rollers 522; the belt 523 is wound around the upper edge of the belt guide 522 and is slidably engaged with the top surface of the belt support plate 521 from the bottom surface. This arrangement provides reliable planar support to the sheet material and prevents the transfer belt 523 from being deformed by the sheet material as it is being bent.

In a preferred embodiment, both sides of the belt supporting plate 521 are wider than the conveying belt 523, and both sides of the belt supporting plate 521 are provided with ribs turned downward, and the lower edges of the ribs shield the portion of the conveying belt 523 around the lower edge of the belt guide roller 522 in the vertical direction, so as to prevent dust from falling on the portion of the conveying belt 523 around the lower edge of the belt guide roller 522.

In the above embodiment, the first pivot shaft 53 and the second pivot shaft 54 are both inserted into the rib of the belt support plate 521 in a rotationally engaged manner.

The gripping device 62 is driven by a servo to move along the plate flowing direction and the vertical direction respectively, so that the lifting frame 621 moves out, stacks and piles the plates on the third conveyor belt 52 through the vacuum suction cups 622. Before the gripping device 62 grips the sheet material through the vacuum suction cup 622, the fifth cylinder 626 drives the hooks 623 to open through the crank 625 so that the sheet material contacts the suction cup from between the hooks 623; after the grabbing device 62 grabs the plate material through the vacuum sucker 622, the fifth cylinder 626 drives the hook 623 to be buckled inwards through the crank 625, so that the edge of the plate material is buckled by the claw part 6230 of the hook 623 and is not liable to fall accidentally; when the gripper 62 releases the sheet, the fifth cylinder 626 again drives the fingers 623 open by means of the crank 625 so that the sheet comes out from between the fingers 623.
