[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices. "Fixed" or "fixed connection" generally refers to common mechanical connection methods, such as threaded connections, welding, or bonding.

[0032] In the existing technology, although the workstation transfer device for the display screen can provide some protection for the display screen during the transfer process, it still requires manual pushing of the display screen for handling and transfer. It cannot realize the transfer of the display screen in a narrow space, and it is difficult to avoid external moisture and dust adhering to the display screen during the handling process, affecting the subsequent testing of the display screen. In addition, it cannot select the direction for feeding the display screen, which makes it difficult to meet production needs.

[0033] This utility model provides a transfer device for waterproof displays, such as... Figure 1 and Figure 2 As shown, in this embodiment, the transfer device includes a vehicle body 1 and an automatic driving module. The bottom of the vehicle body 1 is equipped with wheels 2 for the vehicle body 1 to move within the factory. Compared with the existing manual pushing, this embodiment is equipped with an automatic driving module, which can pre-plan the walking path and set up an obstacle avoidance system. After the display screen is installed on the vehicle body 1, the vehicle body 1 automatically drives to the next workstation, reducing the steps of manual pushing and walking, and meeting the needs of display screen transfer in small spaces.

[0034] To prevent external dust and impurities from contaminating the display screen during transport, the space where the display screen is placed is sealed off during the transportation process. Specifically: such as... Figure 3 and Figure 4 As shown, a placement cavity 3 for placing the display screen is provided inside the vehicle body 1. Doors 4 that can open and close the placement cavity 3 are provided on both sides of the vehicle body 1. The bottom of the door 4 is hinged to the vehicle body 1. A drive component 5 for controlling the opening and closing of the door 4 is provided inside the placement cavity 3. The drive component 5 is a motor. As to how the motor drives the opening and closing of the door 4, it is a relatively mature existing technology and will not be described in detail in this example. When loading the display screen, the drive component 5 drives the door 4 to flip outward to open the door 4, so that the display screen can be placed into the placement cavity 3. After assembly, the drive component 5 is activated again to drive the door 4 to close, forming a sealed space for transportation, which can prevent dust and impurities from entering during transportation.

[0035] To meet the material feeding needs from different directions and improve the stability and ease of entry and exit of the display screens, multiple placement units are evenly arranged in the height direction within the placement cavity 3, and multiple placement plates 6 are spaced apart within the placement cavity 3. In this embodiment, there are four placement units and four placement plates 6. The two sides of the placement plates 6 are fixedly connected to the sides of the placement cavity 3. Each placement plate 6 is provided with one placement unit, and each placement unit is used to place at least one display screen, depending on the size of the display screen. The placement units can move from the doors 4 on both sides of the vehicle body 1 to exit the placement cavity 3, so the direction of opening the doors 4 can be selected according to the actual site requirements to meet the material feeding and unloading needs from multiple directions.

[0036] To stably push out the placement frame 7 for placing and removing the display screen, this embodiment sets the placement unit as a placement frame 7 and an electric push rod 8. The placement frame 7 is set on the upper end of the placement plate 6 and can slide left and right on the placement plate 6 to enter and exit the placement cavity 3. The electric push rod 8 is installed on the door 4, and a push block is provided on its output end. In this embodiment, each door 4 is equipped with four electric push rods 8. When the door 4 is closed, the four electric push rods 8 are at the same height as the four placement frames 7. When it is necessary to push out the placement frame 7, the drive component 5 opens one side of the door 4, and the electric push rod 8 on the other side of the door 4 is ready to start. The lowest electric push rod 8 is started first, and the placement frame 7 is pushed out by the push block, so that the display screen can be placed into or taken out of the placement frame 7. After completion, the placement frame 7 is reset, and then the adjacent electric push rod 8 is started in sequence to carry out the work. The highest electric push rod 8 on the door 4 is started last to meet the movement path of the loading and unloading robot.

[0037] To ensure stable reset of the placement frame 7 after it is pushed out (since the pusher block and placement frame 7 are separate and cannot be pulled back by the electric push rod 8), a reset mechanism is provided, such as... Figure 5 , Figure 6 and Figure 7 As shown, the reset mechanism includes a first limiting block 9, a second limiting block 10, a first slider 11, and a second slider 12. The first limiting block 9 and the second limiting block 10 are fixed to the upper end of the placement plate 6 and are located on both sides of the placement plate 6, respectively. The first slider 11 and the second slider 12 are fixed to the bottom of the placement frame 7 and abut against the upper end of the placement plate 6. The first slider 11 and the second slider 12 slide on the top of the placement plate 6. In other embodiments, rollers can be provided at the bottom of the first slider 11 and the second slider 12 to further ensure the stability of the placement frame 7 moving on the placement plate 6. The first slider 11 and the second slider 12 are both located between the first limiting block 9 and the second limiting block 10, and the first slider 11 is adjacent to the first limiting block 9, and the second slider 12 is adjacent to the second limiting block 10. In addition, it was found in experiments that in order to avoid the placement frame 7 tilting due to instability of the center of gravity after movement, the first limiting block 9, the second limiting block 10, the first slider 11, and the second slider 12 are fixed to the bottom of the placement frame 7 and abut against the upper end of the placement plate 6. The heights are set to be equal to ensure that the tops of the first limiting block 9 and the second limiting block 10 abut against the bottom of the placement frame 7. A reset mechanism is also provided; in this embodiment, a spring is used. Specifically, a first spring 13 is provided between the first slider 11 and the second limiting block 10, and a second spring 14 is provided between the second slider 12 and the first limiting block 9, to ensure that the placement frame 7 has a spring providing a reset force when moving to both sides. A first through-slot 15 is provided on the first limiting block 9 for the first limiting block 9 to pass through, and a second through-slot 16 is provided on the second limiting block 10 for the second limiting block 10 to pass through. The placement of the first through-slot 15 and the second through-slot 16 ensures that the movement of the placement frame 7 is not restricted by the first limiting block 9 and the second limiting block 10 when the placement frame 7 moves to both sides. Furthermore, when the placement frame 7 moves to its limit distance, the first limiting block 9 abuts against the second slider 12, or the second limiting block 10 abuts against the first slider 11, to provide a limiting effect and prevent the placement frame 7 from detaching from the placement plate 6.

[0038] It should be noted that the loading and unloading of this utility model are all done with the help of a robotic arm. The robotic arm places the display screen on the placement frame 7 and removes the display screen. No manual handling is required throughout the process, which can meet the requirements for stable operation in a confined space.

[0039] To prevent the display screen from shaking and being damaged during transportation, several rubber pillars are evenly arranged inside the placement frame 7 to support the display screen, and a rubber protective layer is also provided on the inner side wall of the placement frame 7. The rubber pillars not only prevent the display screen from sliding during transportation, but also provide shock absorption and protect the display screen.

[0040] To facilitate staff to intuitively understand the number and model of the transfer display screens, a display 17 is installed on the vehicle body 1. The display 17 can display the number and model of the display screens in the placement cavity 3, thereby improving work efficiency. At the same time, the display screen can display prompts such as "Workshop transfer, pay attention to avoid" when the vehicle body 1 is moving. In other embodiments, a language module can also be set for voice broadcast prompts.

[0041] To further prevent dust and impurities from adhering to the display screen during its transfer in the workshop, a dust collection mechanism 18 is installed on the top of the placement cavity 3. The dust collection mechanism 18 is also equipped with an electrostatic elimination device and an ultraviolet germicidal lamp to eliminate static electricity generated during the production of the display screen and improve the cleanliness of the placement cavity 3.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
