The oil pumping unit 31, the dirty oil tank 32, the first filter 33, the clean oil tank 34 and the test oil filling machine 24 are sequentially connected through oil pipes.

[0034] The oil pump 31 is used to extract the test lubricating oil in the tested gearbox assembly. The extracted test lubricating oil is first stored in the dirty oil tank 32, and then filtered through the first filter 33 and stored in the clean oil tank 34, waiting to be extracted by the test oil filling machine 24.

[0035] Furthermore, the second refueling device 4 includes a second ID reader 41, a second PLC programmable controller 42, a second electronic scale 43, and a fresh oil dispenser 44.

[0037] A method for filling a transmission with lubricating oil using the above-mentioned transmission lubricating oil filling system comprises the following steps:

[0038] Step a: Use the first refueling device 2 to scan the transmission assembly ID information and pallet information, weigh the transmission assembly and pallet at the same time, and send the transmission assembly ID information, pallet information and weight information to the server 5. The server 5 stores the weight information of all pallets on the production line, and the pallet number corresponds to the pallet weight.

[0039] Step b: the server 5 queries the rated refueling amount based on the transmission assembly ID information sent by the first refueling device 2, and sends the rated refueling amount information to the first refueling device 2;

[0040] Step c: After receiving the rated refueling amount information, the first refueling device 2 refuels the gearbox assembly with the test lubricant oil, and sends the information to the gearbox test bench 1 after the refueling is completed;

[0041] Step d: The gearbox test bench 1 performs offline running-in and testing on the gearbox assembly. After the test is completed, the test result is sent to the server 5. If the test result is qualified, step e is executed. If the test result is unqualified, the gearbox assembly is returned to the factory for repair;

[0042] Step e: Use the oil extraction equipment 3 to extract the test lubricating oil in the gearbox assembly; the extracted test lubricating oil is filtered and stored in the clean oil tank 34;

[0043] In step f, the second refueling device 4 is used to scan the transmission assembly ID information and the pallet information, and the transmission assembly and the pallet are weighed. Then, the rated refueling volume and the weight information measured by the first refueling device 2 are downloaded from the server 5. After the refueling volume to be replenished is calculated, the transmission assembly is filled with clean lubricating oil.

[0044] In a preferred embodiment, step a further includes a step of determining whether the transmission assembly is a repaired transmission. After scanning the transmission assembly ID information and the pallet information, the first refueling device 2 downloads the repair information corresponding to the transmission assembly ID information from the server 5. If there is no repair information, the transmission assembly is determined to be a new transmission assembly, and the transmission assembly and the pallet are weighed. The transmission assembly ID information, the pallet information, and the weight information are then sent to the server 5, and then step b is executed.

[0045] If there is any repair information, the transmission assembly and the pallet are weighed a second time, and the first weighing information of the transmission assembly and the corresponding pallet is downloaded from the server 5. Then, the amount of test lubricant that needs to be replenished is calculated, and after the filling is completed, the information is sent to the transmission test bench 1.

[0046] The following describes in detail a method for filling transmission lubricating oil in conjunction with a specific embodiment:

[0047] Step 1: Use the first ID reading device 21 to obtain the ID information and pallet information of the transmission assembly. The first ID reading device 21 sends the relevant information to the first PLC programmable controller 22. The first PLC programmable controller 22 downloads the repair information corresponding to the ID information from the server 5. If there is no repair information on the server 5, the transmission assembly is considered to be a new transmission assembly and step 2 is executed. If the repair record of the transmission assembly is downloaded, step 5 is executed.

[0048] Step 2: Obtain weight information of the gearbox assembly and the pallet through the first electronic weighing machine 23 and send it to the first PLC programmable controller 22. The first PLC programmable controller 22 sends the weight information of the gearbox assembly and the pallet, as well as the ID information of the gearbox assembly and the pallet information to the server 5;

[0049] Step 3: The server 5 queries the rated refueling amount according to the ID information of the transmission assembly, and sends the rated refueling amount information to the first PLC programmable controller 22;

[0050] Step 4: After receiving the rated refueling amount information, the first PLC programmable controller 22 controls the test oil filling machine 24 to fill the transmission assembly with test lubricating oil. When the test oil filling machine 24 is in operation, the test lubricating oil in the clean oil tank 34 is pumped out and added to the transmission assembly. After the test lubricating oil filling operation is completed, the first PLC programmable controller 22 sends a filling completion signal to the transmission test bench 1, and then executes step 6;

[0051] Step 5: The current weight of the gearbox assembly and the pallet is obtained through the first electronic weighing machine 23, and the weight information is sent to the first PLC programmable controller 22. The first PLC programmable controller 22 downloads the rated refueling amount and the initial weighing weight from the server 5, calculates the amount of test lubricant to be added, and controls the test oil filling machine 24 to add test lubricant to the gearbox assembly. After the test lubricant filling is completed, the first PLC programmable controller 22 sends a filling completion signal to the gearbox test bench 1, and then executes step 6; the test lubricant to be added is equal to the rated refueling amount plus the initial weighing weight minus the current weighing weight;

[0052] Step 6: The gearbox test bench 1 performs offline running-in and testing on the gearbox assembly. After the test is completed, the test result is sent to the server 5. If the test result is qualified, step 7 is executed. If the test result is unqualified, the gearbox assembly is returned to the factory for repair;

[0053] Step 7: Use the pumping unit 31 to extract the test lubricating oil from the gearbox assembly; the extracted test lubricating oil is first stored in the dirty oil tank 32, then filtered through the first filter 33 and stored in the clean oil tank 34;

[0054] Step 8: Use the second ID reader 41 to read the transmission assembly's ID information and pallet information. The second ID reader 41 sends the read information to the second PLC 42. The second electronic weighing machine 43 weighs the current weight of the transmission assembly and pallet and sends it to the second PLC 42. The PLC 42 downloads the rated refueling volume and the weight measured by the first refueling device 2 from the server 5. After calculating the required refueling volume, it controls the new oil dispenser 44 to add clean lubricating oil to the transmission assembly. The required refueling volume is equal to the rated refueling volume plus the initial weight measured by the first refueling device 2 minus the weight measured by the second electronic weighing machine 43.
