The lifting and rotating device 3 is arranged in the middle of the two conveyor belts, and lifts up the material holder that has been transmitted to the right place so that it can reach the area for pasting paper tape. Since paper tape needs to be pasted on both sides of the material holder, the lifting and rotating device 3 can rotate the material holder 180° to achieve double-sided bonding; the paper tape bonding device 4 is arranged above the lifting and rotating device 3, and the tape stretching direction of the paper tape transfer device is perpendicular to the transmission direction of the conveyor belt, so that the paper tape can directly correspond to the side of the material holder after the material holder rises.

[0025] like Figure 4 As shown, the paper tape bonding device 4 includes a support platform 41, a transverse robot 42, a tape unwinding device and a pressing device.

The lifting and rotating device 3 is arranged between the pressing device and the transverse robot 42, so that the rising material seat moves into the bonding operation range. The tape unwinding device is arranged on the support platform 41 at one end of the pressing device. The transverse robot 42 pulls the tape on the tape placement device so that the tape corresponds to the side wall of the material seat to be pasted, and the tape is pressed against the side of the material seat by the opposite pressing device, thereby realizing the function of bonding the tape.

[0026] Among them, the transverse movement robot 42 includes a transverse rail 46 fixed on the support platform 41 and a cutting and pasting robot arranged on the transverse rail 46.

The central axis is vertically arranged with the tape placement disk 46. The paper tape is hung on the central axis to fix the paper tape. The central axis is connected to the torque motor 47. When the paper tape is pulled, the torque motor 47 rotates in coordination to keep the paper tape flat. The clamping device includes a clamping plate 44 and a clamping cylinder 45. The clamping cylinder 45 is fixedly arranged on the support platform 41. The piston end of the clamping cylinder 45 is connected to the clamping plate 44.

The clamping cylinder 45 pushes forward to push the clamping plate 44 to the position of the paper tape and press the paper tape to the side wall of the material seat, thereby achieving bonding. The clamping cylinder 45 includes three evenly arranged ones. When in use, two adjacent cylinders can be pushed together, or three cylinders can be pushed together to bond material seats of different lengths. Different numbers of cylinders are used for different lengths so that the pressing plate 44 is evenly stressed, wherein the middle cylinder is a push cylinder, and the cylinders on both sides are rodless cylinders.

[0028] like Figure 3As shown, the lifting and rotating device 3 includes a lifting device and a rotating device. The lifting device is used to push up the material seat on the transmission device 2, or lower the material seat with the paper tape pasted back to the transmission device 2. The rotating device is used to rotate the material seat with the paper tape pasted on one side by 180°, and turn the other side that is not pasted to the bonding position; the lifting device includes a fixed plate 31, a lifting frame 32, a lifting motor 33 and a lifting transmission mechanism. The fixed plate 31 is fixed on the base 1, and the lifting motor 33 is fixedly arranged on the fixed plate 31. The lifting frame 32 is provided with a rack and a limiting slide rail.

The rotating tray 34 is arranged on the top of the lifting frame 32, and the rotating tray 34 is connected to the cylinder 35 through a rotating transmission device; limiting columns are provided at the four corners of the rotating tray 34 to limit the position of the material seat to avoid displacement during the compression or rotation of the pressing plate 44. The lifting device and the rotating device may adopt other forms of devices, such as using a lifting cylinder to achieve the lifting function.

[0032] Step 3: Rotate the lifting device to flip the material holder 180° and perform step 2 again;

[0033] Step 4: The rotary lifting device descends to put the material holder back into the transmission device. The transmission device moves forward the distance of a material holder operation area so that the next material holder moves to the position of the rotary lifting device, and step 1 is continued.

[0034] The specific operation method is as follows: the material seat moves to the top of the lifting and rotating device 3 under the action of the conveyor belt, and the lifting device drives the lifting frame 32 to rise, so that the material seat is stuck in the rotating tray 34, and moves to be flush with the pressing plate 44 under the action of the lifting device. The second clamping claw 423 clamps the end of the paper tape, and moves horizontally to pull the paper tape out, corresponding to the side of the material seat, and pushes the pressing plate 44 through the pressing cylinder 45 to make the paper tape adhere to the side of the material seat. After pressing, the pressing cylinder 45 retracts, driving the pressing plate 44 to retract; the second clamp is released, and the front structure is The adhesive lifting cylinder 421 retracts under the action of the adhesive lifting cylinder 421, and the cutting and pasting robot moves back to the starting position along the horizontal track 46. The first clamp 422 and the second clamp 423 simultaneously grab the paper tape adhered to the side of the material seat and the middle of the paper tape roll. The cutting knife 424 swings down the cut paper tape, and the first clamp 422 is released. The rotating device controls the rotation of the material seat to turn the other side that is not pasted over, and the paper tape is bonded again. When the paper tapes on both sides are bonded, the lifting device drives the lifting frame 32 to descend, and puts the material seat with the paper tape bonded back on the transmission device 2.
