It is understood that the air outlet of the blower 23 may be connected to the end of the conveying pipe 21 away from the storage tank 22, so that the air blowing from the blower 23 into the conveying pipe 21 can flow the air in the conveying pipe 21 to the storage tank 22, so as to blow the LED chips in the conveying pipe 21 into the storage tank 22.

In one embodiment, referring to fig. 3, 10 and 11, the air inlet 231 of the blower 23 is connected to the exhaust pipe 222 of the material storage tank 22 through a communicating pipe 261, so that the connection is convenient and the position layout of the blower 23 is convenient.

In one embodiment, when there are a plurality of the transfer pipes 21 and the storage tanks 22, the connection pipe 261 may be a multi-way pipe to connect the exhaust pipes 222 of the plurality of storage tanks 22 to the same blower 23.

In one embodiment, the connection pipe 261 is a steel wire hose to facilitate connection between the exhaust pipe 222 of the storage tank 22 and the air inlet 231 of the blower 23. It is to be understood that a rigid pipe may be used as the communication pipe 261.

In one embodiment, the centralized receiving mechanism 20 further comprises a reversing valve 262, and the reversing valve 262 is used for controlling the fan 23 to be communicated with the exhaust pipe 222 or the outside. A direction change valve 262 is provided to generate a negative pressure in the transfer pipe 21 and the stock tank 22 to absorb the LED chip when the direction change valve 262 controls the blower 23 to communicate with the exhaust pipe 222. When the LED chips in the storage tank 22 need to be discharged, the wind direction can be controlled through the reversing valve 262 to be communicated with the outside, so that the air pressure in the conveying pipe 21 is close to or the same as the air pressure outside, the LED chips conveyed to the conveying pipe 21 by the light splitter 10 can be suspended in the conveying pipe 21, the LED chips in the storage tank 22 can be conveniently discharged, and the fan 23 and the light splitter 10 do not need to be stopped.

In addition, when the fan 23 is connected to a plurality of storage tanks 22, if the LED chips in a certain storage tank 22 are discharged, the reversing valve 262 corresponding to the storage tank 22 is only required to be controlled and connected to the outside, and the other storage tanks 22 are still communicated with the fan 23, so that the air pressure in the other storage tanks 22 and the corresponding conveying pipes 21 can be ensured, and the phenomenon that the conveying speed of the LED chips is too high due to sudden rise of air flow and air pressure in the conveying pipes 21 is avoided, so as to protect the LED chips.

In one embodiment, when the communication pipe 261 is provided, the direction change valve 262 is provided between the communication pipe 261 and the exhaust pipe 222 to facilitate controlling the corresponding exhaust pipe 222 to communicate with the air inlet 231 of the blower 23.
