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.

[0027] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] like Figure 1~2 As shown, the specific scheme of the embodiment is as follows: Embodiment 1: A membrane shell automatic stacking device comprises a first conveyor belt 1, a lifting device, a stacking device and an unmanned transport vehicle 2, wherein the lifting device is located between the first conveyor belt 1 and the stacking device.

[0029] The lifting device includes a third conveyor belt 3 and a lift 4. The third conveyor belt 3 is arranged along the axis of the first conveyor belt 1. The lift 4 includes a column and a screw assembly. The frame of the third conveyor belt 3 is slidably connected to the column. The screw assembly includes a screw and a motor.

[0030] The stacking device includes a frame 5, a conveying platform and a guide assembly. The conveying platform is arranged on the top of the frame 5. The guide assemblies are arranged on both sides of the conveying platform respectively. The body of the unmanned guided vehicle 2 is located under the conveying platform.

[0031] A first baffle 501 is provided on one side of the frame 5 facing the lifting device. The first baffle 501 is used to protect the film shell 12 to prevent the film shell 12 on the third conveyor belt 3 from falling during the lifting process.

[0032] The conveying platform includes a second conveyor belt 6 and a release platform 7. The second conveyor belt 6 is located between the release platform 7 and the lifting device. A channel is provided in the middle of the release platform 7. The second conveyor belt 6 and the channel are arranged along the axis of the first conveyor belt 1. The lifting platform 201 of the unmanned guided vehicle 2 is located in the channel after being raised.

[0033] The guide assembly includes a push rod mechanism 8, a guide wheel conveying mechanism 9 and a second baffle 10. The push rod mechanism 8 is respectively located on both sides of the second conveyor belt 6, and the guide wheel conveying mechanism 9 is respectively located on both sides of the release platform 7. Slide rails 11 are also respectively provided on both sides of the release platform 7. The slide rails 11 are set on the frame 5. The guide wheel conveying mechanism 9 is located between the push rod mechanism 8 and the slide rails 11, and the second baffle 10 is slidably connected to the two slide rails 11 respectively.

[0034] The push rod mechanism 8 includes a first fixed frame, an electric push rod 801 and a first guide wheel assembly 802 . The electric push rod 801 is connected to the frame 5 via the first fixed frame, and the first guide wheel assembly 802 is arranged on the piston rod of the electric push rod 801 .

[0035] The first guide wheel assembly 802 includes a first shell and a first guide wheel. The first shell is connected to the piston rod. The first guide wheel is rotatably connected to the first shell. The first guide wheel is used to push the membrane shell 12.

[0036] When the push rod mechanism 8 is working, on the one hand, the first guide wheel assemblies 802 on both sides push the membrane shell 12 to the middle of the second conveyor belt 6. On the other hand, since the spacing of the first guide wheel assemblies 802 is set according to the size of the membrane shell 12, the postures of each membrane shell 12 on the second conveyor belt 6 will be adjusted to the same posture.

[0037] The guide wheel conveying mechanism 9 includes a second fixed frame, a telescopic rod 901 and a second guide wheel assembly 902 . The telescopic rod 901 is connected to the frame 5 via the second fixed frame, and the second guide wheel assembly 902 is arranged on the telescopic rod 901 .

[0038] The second guide wheel assembly 902 includes a second shell, a motor, a transmission chain and a second guide wheel. The second shell is connected to the telescopic rod 901. The motor is arranged on the second shell. The second guide wheel is rotatably connected to the second shell. Sprockets are respectively provided on the output shaft of the motor and the second guide wheel. The sprockets are connected by a transmission chain. The second guide wheel is used to contact the membrane shell 12.

[0039] When the guide wheel conveying mechanism 9 is working, the spacing of the second guide wheel assembly 902 is set according to the size of the membrane shell 12. On the one hand, it limits the change in the posture of the membrane shell 12. On the other hand, it can use the rotating second guide wheel to continue to move the membrane shell 12 to avoid the membrane shell 12 from getting stuck between the second conveyor belt 6 and the release platform 7.

[0040] The unmanned guided vehicle 2 includes a vehicle body, a lifting platform 201 and a scissor-type lifting mechanism. The lifting platform 201 includes a load-bearing plate and a pallet. The pallet is placed on the load-bearing plate, and the load-bearing plate is connected to the vehicle body through the scissor-type lifting mechanism.

[0041] The working method of this embodiment is as follows:

[0042] The film shell 12 that has completed each production process is placed on the first conveyor belt 1, and is transported to the third conveyor belt 3 via the first conveyor belt 1. The third conveyor belt 3 is then lifted by the lifter 4, and the third conveyor belt 3 transports the film shell 12 to the second conveyor belt 6. After adjustment by the push rod mechanism 8, the guide wheel conveying mechanism 9 will assist the third conveyor belt 3 to move the film shell 12 to the channel of the release platform 7.

[0043] The first membrane shell 12 to be stacked gradually moves onto the pallet during the movement toward the release platform 7, and then the scissor-type lifting mechanism drives the pallet to descend, so that the top surface of the first membrane shell 12 is flush with the height of the release platform 7, and the subsequent membrane shell 12 will pass through the top surface of the previous membrane shell 12 and then be stacked on the previous membrane shell 12. When the number of stacked membrane shells 12 reaches a preset value, the lifting platform 201 will completely descend, the unmanned guided vehicle 2 will leave the rack 5 and drive to the storage area, and the forklift in the storage area will unload the pallet and the stacked membrane shells 12 on the pallet.

[0044] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that:

[0045] A TOF laser distance measuring sensor is provided on the first baffle 501, and the TOF laser distance measuring sensor here is used to measure the distance between the membrane shell 12 located on the first conveyor belt 1 or the third conveyor belt 3 and the first baffle 501, so as to monitor in real time whether the membrane shell 12 is completely moved to the third conveyor belt 3, so as to decide when the lifting device starts to work.

[0046] A TOF laser distance measuring sensor is also provided on the second baffle plate 10 , and the TOF laser distance measuring sensor is used to measure the distance between the membrane shell 12 located on the conveying platform and the first baffle plate 501 .

[0047] When the film shell 12 located at the release platform 7 falls onto the lifting platform 201, the lifting platform 201 descends. At this time, the outgoing light of the TOF laser ranging sensor will illuminate the film shell 12 located on the second conveyor belt 6, so that the amplitude of the distance measured by it changes in a short time exceeds the threshold, thereby determining that the film shell 12 located at the release platform 7 has been stacked, facilitating the start of the second conveyor belt 6 to continue stacking, and avoiding collisions caused by the close spacing between the film shells 12.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
