[0046] like Figures 1 to 4 As shown, the utility model provides a nitrogen cabinet 100, which includes a cabinet body 10, and the cabinet body 10 includes two shelves 20 arranged opposite to each other along a first horizontal direction and a guide rail 42 extending along a second horizontal direction, the first horizontal direction is perpendicular to the second horizontal direction, and an accommodating space 30 is provided between the two shelves 20, and the shelves 20 are used to store material boxes 200. Specifically, nitrogen is filled in the nitrogen cabinet 100 for storing material boxes 200 containing PCB boards, and the internal space of the nitrogen cabinet 100 is set to be airtight to prevent the material boxes 200 containing PCB boards from being damp or oxidized on the surface during storage.

[0047] In this embodiment, the nitrogen cabinet 100 further includes a moving mechanism 40 and a driving mechanism 50. The moving mechanism 40 is located in the accommodating space 30. The moving mechanism 40 includes a transfer mechanism 41 that can move in the horizontal direction and the vertical direction. The transfer mechanism 41 includes at least one trolley 411 and at least one turntable 412 for transferring the material box 200. The turntable 412 is used to drive the trolley 411 to rotate so that the trolley 411 transfers the material box 200 located on one side to the other side. The driving mechanism 50 is used to drive the moving mechanism 40 to move so that the moving mechanism 40 transfers the material box 200. Here, the number of trolleys 411 of the transfer mechanism 41 is two, and the number of turntables 412 of the transfer mechanism 41 is two.

[0048] In this embodiment, a mobile mechanism 40 having a transfer mechanism 41 and a driving mechanism 50 are arranged in the nitrogen cabinet 100 to realize the transfer of the material boxes 200 on the shelf 20 by the mobile mechanism 40. Specifically, the transfer mechanism 41 can move in the horizontal direction and the vertical direction, so that the transfer mechanism 41 can realize the transfer of the material boxes 200 at any position on the two shelves 20 inside the cabinet 10, thereby improving the convenience of the transfer of the material boxes 200 in the nitrogen cabinet 100. The transfer mechanism 41 includes a trolley 411 and a turntable 412. Under the action of the driving mechanism 50, the turntable 412 drives the trolley 411 to rotate so that the trolley 411 rotates from one side to the other side, so that the transfer mechanism 41 transfers the material boxes 200 located on the shelf 20 on one side to the shelf 20 located on the other side, thereby realizing an unmanned and convenient logistics warehousing method.

[0049] like Figures 5 to 7 As shown, in this embodiment, the trolley 411 includes at least one clamp 413 and at least one first motor 414, the clamp 413 is used to clamp the material box 200, the first motor 414 is fixedly connected to the clamp 413, each first motor 414 is arranged corresponding to a clamp 413, and the first motor 414 is used to drive the corresponding clamp 413 to move toward a side away from or close to the material box 200, so that the clamp 413 clamps or stores the material box 200. Specifically, the clamp 413 has two arms that can be opened and closed, which are used to clamp the material box 200. The number of clamps 413 of each trolley 411 is two, and the number of first motors 414 is two. In other words, each first motor 414 controls the corresponding clamp 413 to open or close the arms to realize the clamp 413 to take and place the material box 200, and the two trolleys 411 of each transfer mechanism 41 can simultaneously remove two adjacent material boxes 200, thereby improving the transportation efficiency of the material boxes 200 in the nitrogen cabinet 100. Here, each clamp 413 on the trolley 411 of each transfer mechanism 41 can also remove the material box 200 individually.

[0050] In this embodiment, a second motor 417 is provided at the bottom of the turntable 412 for driving the turntable 412 to rotate, thereby driving the trolley 411 to rotate.

[0051] In this embodiment, the transfer mechanism 41 is further provided with a material box scanner 416 for identifying the material box 200 to be clamped, facilitating the storage and positioning of the material box 200, thereby improving the positioning efficiency of the transfer mechanism for the target material box 200, and further improving the storage and access efficiency of the transfer mechanism 41. Here, the number of material box scanners 416 on each trolley 411 is two, and each material box scanner 416 is arranged in a one-to-one correspondence with a clamp 413.

[0052] In this embodiment, the moving mechanism 40 further includes a guide rail 42 and a slide rail 43, the guide rail 42 extends in the second horizontal direction, the slide rail 43 extends in the vertical direction, and the slide rail 43 can slide along the extension direction of the guide rail 42. Specifically, the transport mechanism 41 is arranged on the slide rail 43, and the slide rail 43 and the guide rail 42 are slidably connected, so that the slide rail 43 slides along the extension direction of the guide rail 42 under the drive of the third motor, ensuring that the transport mechanism 41 can be moved to any position in the second direction, thereby improving the storage utilization rate of the material box 200 in the nitrogen cabinet 100.

[0053] In this embodiment, there are two trolleys 411, which are distributed on both sides of the slide rail 43 and are used to clamp the corresponding multiple material boxes 200. Specifically, the two trolleys 411 are distributed on both sides of the slide rail 43 to simultaneously or individually pick up and place the material boxes 200 on the shelves 20 on both sides, thereby improving the transfer efficiency of the transfer mechanism 41 for the material boxes 200.

[0054] In this embodiment, the transfer mechanism 41 further includes at least one material box sensor 415, which is disposed on the clamp 413 and is used to detect the clamping state of the material box 200. Specifically, when the clamp 413 approaches the material box 200, the material box 200 sensor on the clamp 413 senses the material box 200 and transmits a signal to the controller, and the controller controls the motor to drive the two arms of the clamp 413 to clamp, so as to clamp the material box 200. Here, the number of material box sensors 415 for each clamp 413 is one. In other embodiments, each clamp 413 is provided with one material box sensor 415 on each arm.

[0055] In this embodiment, an identification code is provided on the top of each material box 200. When the clamp 413 clamps the material box 200, the motor first controls the arms of the clamp 413 to open and drives the clamp 413 to move toward the side close to the shelf 20. When the material box 200 sensor of the clamp 413 recognizes the material box 200, the material box scanner 416 scans and confirms the identification code on the top of the material box 200. After confirming that it is the target material box 200, the motor controls the arms of the clamp 413 to tighten and drive the clamp 413 to move toward the side away from the shelf 20, so as to clamp the target material box 200 and drive the trolley 411 to rotate to the target position under the drive of the second motor, or drive the trolley 411 to move to the target position in the horizontal direction or vertical direction under the drive of the third motor.

[0056] Figure 8 is a schematic structural diagram of a cabinet door according to an embodiment of the utility model, Fig. 9 It is a schematic front view of a cabinet door according to an embodiment of the utility model.

[0057] like Figure 8 and Fig. 9 As shown, in this embodiment, the nitrogen cabinet 100 further includes a cabinet door 60, which is located at one side of the first horizontal direction of the cabinet body 10, and the cabinet door 60 is provided with a material transfer channel 62 for feeding and discharging the material box 200. Specifically, the cabinet door 60 is arranged at the center position of one side of the first direction of the cabinet body 10, that is, the cabinet door 60 is located at the side of the cabinet body 10 where the shelf 20 is located, and the material transfer channel 62 is arranged in the cabinet door 60, which facilitates the transportation of the material box 200, and prevents external air and water vapor from entering the interior of the cabinet body 10, and prevents the material box 200 in the cabinet body 10 from being damp and oxidized.

[0058] In this embodiment, the cabinet door 60 further includes a first cabinet door 62 and a second cabinet door 63. The first cabinet door 62 is arranged on the outer side of the material transfer channel 62 to isolate the external gas. The second cabinet door 63 is located on the side close to the accommodating space 30. The second cabinet door 63 and the first cabinet door 62 jointly define the material transfer channel 62. Specifically, the first cabinet door 62 and the second cabinet door 63 are respectively arranged on both sides of the material transfer channel 62. That is to say, when the material box 200 is transported into the cabinet 10, the first cabinet door 62 is opened first, and after the material box 200 is placed in the material transfer channel 62, the first cabinet door 62 is closed, and then the second cabinet door 63 is opened. The transfer mechanism 41 transfers the material box 200 in the material transfer channel 62 to the shelf 20. After the material boxes 200 in the material transfer channel 62 are all transferred to the shelf 20, the second cabinet door 63 is closed to prevent the external air and water vapor from entering the cabinet 10, and to prevent the material boxes 200 in the cabinet 10 from being damp and oxidized.

[0059] In this embodiment, when outputting the material box 200 to the outside of the nitrogen cabinet 100, the second cabinet door 63 is first opened, and after the material box 200 to be output is placed in the material transfer channel 62, the second cabinet door 63 is closed, and then the first cabinet door 62 is opened. The transfer device outside the nitrogen cabinet 100 transfers the material box 200 in the material transfer channel 62 to the outside of the nitrogen cabinet 100. After the transfer of the material box 200 in the material transfer channel 62 is completed, the first cabinet door 62 is closed to prevent external air and water vapor from entering the cabinet 10, thereby preventing the material box 200 in the cabinet 10 from being damp and oxidized.

[0060] In this embodiment, the material transfer channel 62 is provided with stacked material storage platforms 611, which are used to carry the material boxes 200, so that multiple material boxes 200 can be transported or output through the material transfer channel 62 each time, thereby improving the transfer efficiency of the material boxes 200. Here, each material storage platform 611 is provided with multiple storage spaces, and each storage space corresponds to a material box 200.

[0061] In this embodiment, the second cabinet door 63 is configured as a push-pull cabinet door 60. Specifically, the second cabinet door 63 is an up-and-down push-pull cabinet door 60 or a left-and-right push-pull cabinet door 60, so as to avoid the traditional rotary cabinet door 60 from occupying too much accommodation space 30 when opened, thereby avoiding obstruction of the operation of the transfer mechanism 41.

[0062] In this embodiment, the nitrogen cabinet 100 is further provided with an air inlet pipe 11 and an exhaust pipe 12 for charging and discharging nitrogen. Specifically, the air inlet pipe 11 is arranged at the bottom of the cabinet 10, and the exhaust pipe 12 is arranged at the top of the cabinet 10, so as to facilitate charging and discharging nitrogen.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
