METHOD FOR WEIGHING INJECTION QUANTITY OF BATTERY ELECTROLYTE, AND INJECTION QUANTITY WEIGHING DEVICE FOR ELECTROLYTE

PURPOSE:To precisely weigh the injection quantity of an electrolyte from a difference between the weights of a battery body case before and after electrolyte injection, and also store the air bag data before electrolyte injection by a work carrying jig, thereby precisely weighing the injection quantity of the electrolyte. CONSTITUTION:A required battery body case 2 is installed on the installing recessed part 1b of a work carrying jib 1, and carried to a weighing part 4. The air bag of the battery body case 2 is weighed by the weighing part 4, the air bag data is transmitted to and stored in an arithmetic control part 8, and the air bag data is also written into the built-in memory element 3 of the work carrying jig 1 through a data writing part 5. Thereafter, the battery body case 2 installed on the work carrying jig 1 is carried to an electrolyte injecting device 9 to inject a required quantity of electrolyte, and the total weight after the electrolyte injection is measured. The thus-measured total weight is transmitted to and stored in the arithmetic control part 8.
