[0032] In a preferred embodiment of the present invention, the cell transfer device 2 is a translation suction cup or a manipulator with a suction cup.

[0033] In a preferred embodiment of the present invention, the glue station 7 includes a piezoelectric glue dispensing valve and a glue dispensing valve controller, the piezoelectric glue dispensing valve is connected to the glue dispensing valve controller, and the glue dispensing valve controller is connected to the control system 1. Preferably, the first electronic balance 5 and the second electronic balance 8 are connected to a data collector, and the data collector is respectively connected to the glue dispensing valve controller and the control system 1. Further preferably, the data collector is interconnected with the glue dispensing valve controller via RS485, Ethernet or USB.

[0034] In a preferred embodiment of the present invention, the first electronic balance 5 and the second electronic balance 8 are electromagnetic balances.

[0035] In a preferred embodiment of the present invention, the specifications and performance parameters of the first electronic balance 5 and the second electronic balance 8 are consistent.

[0036] In a preferred embodiment of the present invention, the first electronic balance 5 and the second electronic balance 8 are arranged on the same table.

[0037] The working method of the dispensing system for optimizing the dispensing amount control of the matrix stack assembly includes:

[0038] The gluing station 7 is provided with a preset value for the amount of glue; the battery cell transporting device 2 arranged on the guide rail 3 takes out the battery cell from the material box 4 and weighs it at the first electronic balance 5 before gluing, the battery cell transporting device 2 transports the battery cell to the positioning station 6 for positioning, transports it to the gluing station 7 for gluing, and transports it to the second electronic balance 8 for weighing after gluing, the weight value of the battery cell before and after gluing is sent to the gluing station 7, and is compared with the preset value of the amount of glue, and the amount of glue is controlled by adjusting the glue dispensing parameters, and the glue dispensing parameters include the outlet pressure, voltage and glue dispensing time.

[0039] The present invention will be further explained below with a specific embodiment:

[0040] During operation, first enter the set value of the glue dispensing amount in the glue dispensing valve controller, and 15 mg is used in this embodiment. The translation suction cup installed on the guide rail 3 absorbs the battery cell from the material box 4 and passes through the first electronic balance 5, the positioning table 6, the glue dispensing table 7, and the second electronic balance 8 in sequence to complete the weighing-glue dispensing-weighing process. The electronic balance data collector sends the mass of the battery slice before and after gluing to the glue dispensing valve controller through RS485, Ethernet or USB communication. The glue dispensing valve controller obtains the current glue dispensing amount through the internally set difference calculation program and compares it with the set value.

[0041] If the mass of the battery slice before gluing is 4.550g, and the mass of the battery slice after gluing is 4.562g, then the current glue dispensing amount is 12mg, which means that the glue dispensing amount is too little, and it is necessary to change the glue dispensing parameters of the glue dispensing valve to increase the glue dispensing amount. At this time, the glue dispensing valve controller sends instructions to the relevant components of the glue dispensing valve to increase the outlet pressure, increase the voltage and extend the glue dispensing time. Among them, the outlet pressure is adjusted at an interval of 0.02MPa, the voltage is adjusted at a ratio interval of 5%, and the glue dispensing time is adjusted at an interval of 0.2ms. Through multiple glue dispensing amount metering and feedback control, it is ultimately ensured that the glue dispensing amount reaches the set value.

[0042] If the mass of the battery slice before gluing is 4.550g and the mass of the battery slice after gluing is 4.568g, the current amount of glue dispensed is 18mg, which means that the amount of glue dispensed is too much. It is necessary to change the dispensing parameters of the dispensing valve to reduce the amount of glue dispensed. At this time, the dispensing valve controller sends a command to the dispensing valve to reduce the outlet pressure, lower the voltage and shorten the dispensing time. The parameter adjustment interval is as described above and remains unchanged. Through multiple dispensing amount metering and feedback control, it is finally ensured that the dispensing amount reaches the set value.

[0043] It should be noted that what is described in the embodiment is only a preferred implementation of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
