DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown: a sheet transfer and reversing device is used to transfer sheets 1 from two different workstations 2, which includes a base with a seat plate 3, and the seat plate 3 is located between the two workstations 2. A rotating shaft 4 rotatably mounted on the seat plate 3 is fixedly sleeved with a gear 401 on its outer side. The gear 401 can cooperate with a rack 501 provided on the seat plate 3 to drive the rotating shaft 4 to reciprocate. When the rotating shaft 4 rotates, the adsorption plate 8 provided on the upper side thereof moves accordingly to transfer the sheet 1 adsorbed from one workstation 2 to another workstation 2.

[0021] Furthermore, a material transfer cylinder 6 is fixed to the top of the above-mentioned rotating shaft 4 through the top plate 402, and the cylinder shaft of the material transfer cylinder 6 is connected to a long plate-shaped material picking arm 601. A rotating cylinder 7 is installed at the end of the material picking arm 601, and the adsorption plate 8 and the rotating cylinder 7 are combined with each other; when the rotating shaft 4 rotates, the material picking arm 601 moves back and forth between the lifting station 201 and the rotating station 202. When it reaches the designated station 2 for material transfer, the material transfer cylinder 6 drives the adsorption plate 8 to move downward to take out or put in the sheet 1.

[0022] Specifically, the seat plate 3 is laterally fixed with a rack cylinder 5 and a guide slide bar 502 through a support frame. The rack 501 that cooperates with the gear 401 is slidably sleeved on the guide slide bar 502, and the plug-in column connected to the cylinder shaft of the rack cylinder 5 is inserted into the slot opened on the back of the rack 501. When the cylinder shaft of the rack cylinder 5 is extended or retracted, the rack 501 will be pulled back and forth on the guide slide bar 502 accordingly, thereby driving the rotating shaft 4 to rotate.

[0023] Specifically, a dust seat 403 is installed on the periphery of the above-mentioned rotating shaft 4. The dust seat 403 is locked and combined with the base plate 3. The side wall thereof is provided with a notch for exposing the gear 401. The rack 501 is driven and cooperated with the gear 401 at the notch to drive the rotating shaft 4 to rotate. The dust seat 403 can reduce the efficiency of external erosion of the rotating shaft 4 and the gear 401, so as to extend the service life of the device.

[0024] Furthermore, the above-mentioned stations 2 are respectively a lifting station 201 and a rotating station 202. The lifting station 201 is a support plate 211 with a lifting function, and the sheets 1 are placed on the support plate 211 in a stacked state; and the rotating station 202 is installed on a rotating disk 212, and a plurality of fixtures 222 are arranged in a ring shape, and each fixture 222 is used to place a sheet 1 separately. The above-mentioned adsorption plate 8 can transfer the sheet 1 of the rotating station 202 to be stacked on the lifting station 201, or transfer the sheet 1 of the lifting station 201 to be placed separately on the rotating station 202.

[0025] Specifically, in the present design, the lifting station 201 further includes a fixed plate 221, and the fixed plate 221 is detachably mounted with a plurality of limiting rods 231 in a magnetic manner. The limiting rods 231 are mutually enclosed to form a limiting area that matches the contour of the sheet 1. The liftable support plate 211 is located in the limiting area. When the sheet 1 is stacked on the support plate 211, its side is also restricted by the limiting rods 231 to avoid being affected by material removal or feeding. Of course, the fixed plate 221 as a whole can be directly made of magnetic material, so that the limiting rods 231 can be combined with the fixed plate 221 at any position on the fixed plate 221, thereby enclosing different limiting areas to match sheets with different contours.

[0026] Specifically, the reason why the pallet 211 of the above-mentioned lifting station 201 has the lifting function is that when taking or feeding materials, the thickness of the sheet 1 stacked on the pallet 211 will also change accordingly; in order to ensure the smooth progress of the material transfer process, the present design is provided with a lifting motor 241 under the fixed plate 221, and the motor shaft of the lifting motor 241 can drive the pallet 211 to move up and down through the screw assembly 251 and the top rod 261 to compensate for the height difference that may exist between the adsorption plate 8 and the sheet 1.

[0027] Working method (sheet transfer from the rotating station to the lifting station): First, the rotating shaft drives the picking arm to rotate toward the rotating station. When it reaches the top of the rotating station, the suction plate sucks the sheet upward; then, the rotating shaft rotates in the opposite direction to transfer the sheet to the top of the lifting station. At the same time, the rotating cylinder drives the suction plate and the sheet to fine-tune their own direction to match the limit area set by the lifting station; finally, the suction plate puts the sheet into the lifting station and repeats the picking process again along with the rotating shaft.

[0028] As mentioned above, the electric suction cup can transfer the taken-out sheet to another station. Under normal circumstances, when the sheet is transferred between different stations, the layout of the stations will directly affect the feeding effect. Specifically, the orientation of the two stations must be consistent before the above design can be used for material transfer. In the process of realizing the sheet transfer, this design can synchronously change the orientation of the sheet with the help of a rotating cylinder, so that the sheet can be directly put into it when it moves to different stations, which speeds up the transfer efficiency of the sheet to a certain extent and improves the scope of application of the overall structure.
