[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0044] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0045] like Figures 1-10As shown, the present invention provides a packaging method for flexible glass, comprising:

[0046] Step 1: Place the hard plate at the designated location, and then set a buffer layer on the hard plate;

[0047] Step 2: Stack paper and flexible glass on the buffer layer in sequence, and repeat the operation until enough layers are stacked;

[0048] Step 3: Place a buffer layer and a hard board on the stacked paper in sequence;

[0049] Step 4: Use tape to glue the left, middle, and right sides of the two hardboards together;

[0050] Step 5: Then selectively place it into a vacuum bag for vacuum packaging.

[0051] The working principle and beneficial effects of the above technical solution: During actual use, after placing a hard plate at a designated position, a buffer layer is set on the hard plate, and then paper and flexible glass are stacked in sequence on the buffer layer, and the operation is repeated to stack a sufficient number of layers. After stacking, a buffer layer and a hard plate are placed in sequence on the paper, and then the left, middle and right sides of each of the two hard plates are glued together with tape, and then vacuum-packed as needed. The flexible glass is packaged by stacking, which avoids the problems of deformation and bending in the flexible glass packaging process and reduces production costs.

[0052] In one embodiment, the hard board material is any one of a plastic board and a composite board.

[0053] The working principle and beneficial effects of the above technical solution: Plastic boards and composite boards have high hardness and are relatively cheap, which can reduce production costs and improve packaging effects.

[0054] In one embodiment, the buffer layer is made of any one of a rubber material and a high-density sponge material.

[0055] The working principle and beneficial effects of the above technical solution: rubber material and high-density sponge both have good cushioning effects and are inexpensive.

[0056] In one embodiment, in step 2, the stacking of the paper and the flexible glass is completed by a stacking device.

[0057] The working principle and beneficial effects of the above technical solution: The flexible glass and paper can be quickly stacked at intervals through the stacking device, reducing labor costs.

[0058] In one embodiment, the stacking device comprises:

[0059] A stacking seat 12, on which a paper placement block 10 and a placement slot 11 are arranged side by side;

[0060] Transport devices are evenly provided on both sides of the stacking seat 12;

[0061] The glass conveying block 1 is arranged on one side of the stacking seat 12 . The top of the glass conveying block 1 is arranged on the belt conveyor 2 and a plurality of infrared sensors 3 . The infrared sensors 3 are located on both sides of the belt conveyor 2 .

[0062] The working principle and beneficial effects of the above technical solution: During actual use, the flexible glass is transported by the belt conveyor 2 on the glass conveying block 1. When multiple infrared sensors 3 detect the flexible glass, it means that the flexible glass has reached the designated position. Then the flexible glass and paper are picked up by the handling device and stacked, avoiding manual stacking.

[0063] In one embodiment, the transport device comprises:

[0064] A robot slide rail 4 is provided on one side of the stacking seat 12 and a robot 5 is provided on the robot slide rail 4;

[0065] A transport tube 6 is provided on the robot 5. A plurality of transport columns 7 are provided on the side of the transport tube 6 away from the robot.

[0067] The working principle and beneficial effects of the above technical solution: During actual use, the robot 5 moves downward to drive the transport tube 6 to move downward, and the transport rod 6 drives the suction pipe 8 to move downward through the transport column 7, so that the suction pipe 8 drives the suction cup 9 to move downward and contact the flexible glass and paper, and then the fan (not shown in the figure) is started to make the suction cup absorb the flexible glass and paper, and then the robot 5 rises and slides along the robot slide rail 4. After sliding to the top of the placement slot 11, it puts down the flexible glass or paper and starts stacking.

[0068] In one embodiment, a paper placement slot 13 is provided at the top of the paper placement block 10 , and a separation block 14 is symmetrically provided on the inner wall of the paper placement slot 13 , and one side of the separation block 14 is serrated.

[0069] The working principle and beneficial effects of the above technical solution: During actual use, after the paper is adsorbed by the suction cup, when it leaves the paper placement slot 13, the side edge of the paper will contact the serrated edge of the separation fastener 14, thereby generating vibration, so that the multiple layers of paper stuck together are separated, preventing the conveying device from conveying multiple papers at a time.

[0070] In one embodiment, an alignment device is further provided in the placement slot 11, and the alignment device includes:

[0071] A motor 48 is disposed in the placement slot 11;

[0073] A second pushing device, wherein two adjacent second pushing devices are symmetrically arranged in the placement groove 11;

[0074] The second pushing device includes: a bidirectional threaded rod 15, which rotates through two limit blocks 17, and the two limit blocks 17 are fixed in the placement slot 11, and a hinge block 18 is connected to the bidirectional threaded rod 15 through a threaded sleeve, and the bidirectional threaded rod 15 is provided with a second bevel gear 23, and the second bevel gears 23 of the two adjacent second pushing devices are meshed and connected; a limit groove 16, which is provided in the placement slot 11, and the limit groove 16 is located on one side of the limit block 17; a first L-shaped rod 19, one end of the first L-shaped rod 19 is connected to the hinge block 18, and the other end of the first L-shaped rod 19 is connected to the first sliding block 20, and the first sliding block 20 is slidably connected to the limit groove 16; an alignment plate 22, and the alignment plate 22 is hinged to the two adjacent hinge blocks 18 respectively through a hinge rod 21, and an elastic block 46 is provided at the bottom end of the alignment plate 22;

[0075] The alignment device further includes: a positioning device, the positioning device is provided on one of the second pushing devices, the positioning device includes: a positioning motor 25, the positioning motor 25 is provided on the placement slot 11, and the positioning motor 25 is provided with a threaded rod 26;

[0076] A positioning block 27 is threadedly connected to the threaded rod 26. The positioning block 27 is connected to a second sliding block 28 via a second L-shaped rod 29. The second sliding block 28 is slidably connected to the limiting groove 16. The positioning block 27 is provided with a positioning groove 30, and a pressure sensor 32 is provided in the positioning groove 30.

[0077] A trigger device, the trigger device is provided at the bottom end of the hinge block 18;

[0078] The trigger device comprises:

[0079] A trigger block 31, wherein the bottom end of the trigger block 31 is arc-shaped and the top end of the trigger block 31 is provided with a connecting groove 33;

[0080] A connecting rod 35, one end of which is connected to the bottom end of the hinge block 18, and the other end of which is slidably connected to the connecting groove 33. A spring 34 is sleeved on the connecting rod 35, and the spring 34 is located between the trigger block 31 and the hinge block 18.

[0081] The working principle and beneficial effects of the above technical solution: in actual use, the positioning motor 25 is controlled to rotate according to the size of the flexible glass to be packaged, the positioning motor 25 drives the threaded rod 26 to rotate, and the threaded rod 26 drives the positioning block 27 to reach the specified position; then the hard plate is placed in the placement groove 11, and the motor 48 is started. The motor 48 drives the bidirectional threaded rod 15 to rotate, and the bidirectional threaded rod 15 drives the two adjacent hinge blocks 18 to move toward each other through the thread, so that the hinge block 18 drives the alignment plate 22 to move through the hinge rod 21. During the movement of multiple alignment plates 22 toward the center, the elastic block 46 at the bottom end of the alignment plate 22 drives the hard plate to move, and under the action of multiple alignment plates 22, the hard plate moves to the middle position of the placement groove 11. After the hard plate moves to the middle position of the placement groove 11, the alignment plates 22 that move relatively are moved. Under the action of , the elastic block 46 will be deformed, thereby pressing the edge of the hard plate, completing the centering and fixation of the hard plate, making it convenient for the subsequent handling device to carry the flexible glass and paper for positioning and stacking. At this time, the hinge block 18 drives the trigger block 18 to just enter the positioning groove 30 and trigger the pressure sensor 32, so that the motor 48 stops working; then after placing the buffer layer on the hard plate, the handling device carries the paper and flexible glass. When the paper and flexible glass are stacked in the case of deviation, the edge of the paper or flexible glass will bend upward under the action of the alignment plate 22. After the handling device puts down the paper or flexible glass, under the action of gravity, the bent part of the paper or flexible glass will move downward, thereby completing the alignment, avoiding the problem of uneven stacking of paper and flexible glass due to deviation during transportation, and facilitating subsequent packaging.

[0082] In one embodiment, a detection device is further provided in the alignment plate 22, and the detection device includes:

[0083] An air blowing slot 36 , the air blowing slot 36 being provided on the alignment plate 22 , and a fan being provided in the air blowing slot 36 ;

[0084] A distance measuring sensor 39 is provided on the alignment plate 22 and is located above the air blowing slot 36 ;

[0085] The blade 37 is provided in the blowing groove 36. Both ends of the blade 37 are rotatably connected to the inner wall of the blowing groove 36 through a rotating device. The rotating device includes:

[0086] Rotating groove 38, a rotating groove 38 is provided on the inner wall of the blowing groove 36;

[0087] A rotating rod 40, one end of which is fixedly connected to the blade 37, and the other end of which is rotatably connected to the inner wall of the rotating groove 38. The rotating groove 40 is provided with a rotating groove 45, and the rotating groove 45 is provided inside the first magnetic piece 44 and the second magnetic piece 43. The first magnetic piece 44 and the second magnetic piece 43 are not on the same straight line, and the rotating groove 45 is an inner circular groove;

[0088] A rotating block 42 is slidably connected to the rotating groove 45 , and an electric telescopic rod 41 is fixed between the rotating block 42 and the inner wall of the rotating groove 38 ;

[0089] The iron piece 47 is provided on the outer wall of the rotating block 42 .

[0090] The working principle and beneficial effects of the above technical solution are as follows: in actual use, when the paper and flexible glass are placed in the conveying device, the fan will blow air toward the middle of the paper or flexible glass through the blades 37 on the blowing slot 36, blowing away the dust and debris on the paper and flexible glass, thereby improving the packaging effect; when the flexible glass and paper are put down by the conveying device and after a preset time, the distance sensor 39 detects the distance between the paper or flexible glass. When there is a difference in the detection values ​​detected by multiple distance sensors 39, one distance value measured is greater than the other distances. When the value is reached, it means that the paper and the flexible glass are still bent. At this time, the electric telescopic rod 41 corresponding to the distance sensor that measures a larger distance value is started. The electric telescopic rod 41 extends and drives the rotating block 42 to move toward the direction of the blade 37, so that the iron sheet 47 is separated from the second magnetic sheet 43. The first magnetic sheet 44 and the iron sheet 47 are on the same circumference, and under the action of the wind blown by the fan, the first magnetic sheet 44 and the iron sheet 47 are fitted together. Under the action of the blades, the wind blown by the fan blows downward along the corresponding alignment plate 22, flattening the bent parts of the paper and the flexible glass, thereby improving the alignment accuracy of the alignment device.
