[0028] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] See also Figure 1 The utility model discloses a material transfer and conveying system for conveying sampling cans between a detection room and a sampling point, including a main conveying pipe 1, a first conveying branch pipe 2, a second conveying branch pipe 3, a conveying channel 11, a transfer component (not shown in the figure), a temporary storage device 7, a dust filtering device 8, a pneumatic conveying device and a PLC.

[0030] The main conveying pipeline 1 has an air supply end and a delivery end facing each other, with a sampling canister storage area 9 disposed between the air supply end and the delivery end. The air supply end is connected to a pneumatic conveying device for providing positive or negative pressure to the main conveying pipeline 1. The delivery end is connected to a first delivery branch pipe 2 and a second delivery branch pipe 3 arranged in parallel. The first delivery branch pipe 2 is connected to a detection chamber; the second delivery branch pipe 3 is connected to the sampling device. The delivery end is provided with a switching device for controlling the independent connection between the delivery end and the first delivery branch pipe 2 or the second delivery branch pipe 3. In this embodiment, the pneumatic conveying device is specifically a fan 6, which can provide positive or negative pressure to the main conveying pipeline 1 to move the sampling canister 10 forward or reverse within the main conveying pipeline 1 and the first and second delivery branches 2 and 3. The sampling canister storage area 9 is located on the side of the main conveying pipeline 1 near the fan 6. The sampling canister 10 conveyed into the main conveying pipeline 1 by the first and second delivery branches 2 and 3 can be moved and temporarily stored in the sampling canister storage area 9. The main transmission pipe 1, the first transmission branch pipe 2 and the second transmission branch pipe 3 are all transparent acrylic tubes, which makes it easy to check the equipment status and working status in the pipeline at any time.

[0031] In this embodiment, the switching device may include a first valve 4 and a second valve 5. The first and second transfer branches 2, 3, and main transfer pipeline 1 have the same inner diameter to ensure stable movement of the sampling canister 10 within the pipeline. One end of each of the first and second transfer branches 2, 3 is connected to the delivery end of the main transfer pipeline 1, and the first and second transfer branches 2, 3 are connected in parallel. The other end of the first transfer branch 2 is connected to the detection chamber. A first valve 4 is provided on the first transfer branch 2. The other end of the second transfer branch 3 is connected to the sampling device. A second valve 5 is provided on the second transfer branch 3. Photoelectric sensors (not shown) are provided on the sample canister delivery paths of the first and second transfer branches 2, 3, respectively. The photoelectric sensors include a light emitter and a light receiver disposed opposite to the sample canister delivery paths of the first and / or second transfer branches 2, 3, for detecting whether a sample canister 10 is being transported within the first and / or second transfer branches 2, 3. The first valve 4 and the second valve 5 are both electrically controlled valves and are connected to the PLC electrical signal respectively, and the photoelectric sensor is also connected to the PLC electrical signal. When the second valve 5 is controlled to be closed and the first valve 4 is opened, under the action of positive pressure or negative pressure, the sampling tank 10 can move between the sampling point and the sampling tank storage area 9 through the first transmission branch 2 and the main transmission pipeline 1 that are interconnected; when the first valve 4 is controlled to be closed and the second valve 5 is opened by the PLC, under the action of positive pressure or negative pressure, the sampling tank 10 can move between the detection room and the sampling tank storage area 9 through the second transmission branch 3 and the main transmission pipeline 1 that are interconnected. Of course, it is obvious from the above description that the first transmission branch 2 and the second transmission branch 3 can both be provided with multiple sub-branches to realize that multiple sampling points can deliver samples to multiple detection rooms respectively. Specifically, the PLC controls the opening and closing of the first valve 4 and the second valve 5 according to the signal feedback from the photoelectric sensor. The PLC control system confirms the position of the sampling tank 10 through the photoelectric sensor arranged in the conveying pipe. When it is detected that the main conveying pipe 1 and the first conveying branch pipe 2 and the second conveying branch pipe 3 are all in an idle state, the PLC control system controls the first valve 4 to close and the second valve 5 to open, and controls the pressure in the pipe, and sucks the sampling tank 10 in the automatic sampling device into the second conveying branch pipe 3 and the main conveying pipe 1 in sequence through negative pressure; when the PLC control system detects that the detection room is idle, it controls the switching device to close the second valve 5 and open the first valve 4, and conveys the sampling tank 10 in the sampling tank storage area 9 to the detection room through the main conveying pipe 1 and the first conveying branch pipe 2 through positive pressure.

[0032] In some embodiments, the switching device may further include a guide paddle (not shown) located at the delivery end, and a drive device for controlling the guide paddle to switch the blocking direction. The guide paddle is conventional technology and can be used as long as it can achieve the blocking effect of the first delivery branch pipe or the second delivery branch pipe under the action of the drive device, thereby controlling the independent communication between the delivery end and the first delivery branch pipe or the second delivery branch pipe.

[0033] Furthermore, the system also includes a conveying tank (not shown in the figure) that can be moved pneumatically in the main conveying pipe 1. The sampling tank 10 can be placed in the conveying tank. The outer wall of the conveying tank and the inner wall of the main conveying pipe 1 are gap-matched to improve air tightness, ensure negative pressure or positive pressure conveying power, and prevent low delivery efficiency or delivery failure of the sampling tank 10 due to air leakage.

[0034] Furthermore, in the field of positive electrode materials, the sample in the sampling tank 10 is fine powder particles, and sample residue is inevitable on the outer wall of the sampling tank 10 during the sampling process. When the fan 6 provides negative pressure, the dust remaining in the sample will inevitably enter the fan 6 and cause damage to the fan 6. Therefore, a dust filtering device 8 is provided between the fan 6 and the main transmission pipe 1 to prevent dust from entering the fan 6.

[0035] Further, combined with Figure 1 and Figure 2When multiple second transmission branches 3 are provided, since the sampling can storage area 9 of the main transmission pipeline 1 can only store one sampling can 10 at a time, the next sampling point cannot transfer a new sampling can 10 to the sampling can storage area 9 before the sampling can 10 is transferred to the detection chamber via the first transmission branch 2. Therefore, a temporary storage device is also provided for temporarily storing excess sampling cans 10. The temporary storage device is connected to the storage area of the main transmission pipeline 1 through a conveying channel 11. A transfer assembly (not shown in the figure) is provided in the conveying channel 11. The transfer assembly can be a conveyor belt assembly or a transfer assembly of other mechanical structures such as a manipulator. This part is prior art and there are many options, so it will not be described in detail. The temporary storage device includes a temporary storage rotating tray 71 that can rotate around a main axis 72. The temporary storage rotating tray 70 is located at the end of the conveying channel 11. The temporary storage rotating tray 71 is provided with multiple sample placement positions 73. The sample placement positions 73 are used to place sampling cans 10. The transfer assembly can transfer the sampling cans 10 between the sampling can storage area 9 and the temporary storage rotating tray. It should be noted that the sample placement positions 73 can also be used to place empty sampling cans 10. Empty sampling cans 10 can be transported via the delivery channel 11 to the main conveying pipe 1 and then into the second conveying branch pipe 3 for transfer to the sampling point for sampling. After sampling, they are transported via the second conveying branch pipe 3 and the main conveying pipe 1 to a temporary storage device or a testing room. During typical production, three empty cans are stored in the three sample placement positions 73, and one storage area is set as a buffer zone. This buffer zone does not contain sampling cans 10, but is used for system scheduling or to store samples that are not urgently tested.

[0036] Furthermore, in order to ensure the airtightness of the main transmission pipeline 1, a switchable airtight component is provided at the connection between the delivery channel 11 and the main transmission pipeline 1, such as a sealing door electrically connected to the PLC.

[0037] The working principle of the material transfer transmission system of this utility model is:

[0038] First, the sampling is completed in the automatic sampling and packaging device. After sampling, the materials are stored in the storage area. Then, the sampled storage tanks are stored or sent through the PLC control system. The packaging and storage time can be set in the PLC control system, or tasks can be issued to the DCS and MES through remote control. Specifically, the PLC control system confirms the position through the photoelectric sensors set in the first transmission branch pipe 2, the second transmission branch pipe 3 and the main transmission pipe 1. When it is detected that the system pipeline is in an idle state, the PLC controls the fan 6 to adjust the pressure in the pipeline, and the samples packaged by the automatic sampling and packaging device are sucked in by negative pressure. The sample can 10 goes to the second conveying branch 3 and the main conveying pipe 1 in turn. When the PLC control system detects that the detection room is idle, it controls the switching actuator to transport the sampling can 10 located in the sampling can storage area 9 to the detection room through the main conveying pipe 1 and the first conveying branch 2. After the detection is completed, the PLC control system transports the empty sampling can 10 to the sampling can storage area 9 through negative pressure, and then transports the empty sampling can 10 to the sampling point through positive pressure, or moves the empty sampling can 10 to the temporary storage rotating tray 71 through the conveying channel 11 for automated management to achieve the purpose of production line quality management and control.

[0039] In summary, the material transfer and transmission system provided by the present invention has a complete control system. In the PLC control system, the sample delivery time and frequency can be directly set on the equipment panel. At the same time, the control system can receive DCS and MES control signals for sampling, scheduled sending and reminder functions; the conveying pipeline is made of acrylic material, which reduces the hidden dangers of metal foreign matter in the production process and is transparent and easy to maintain.
