Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0020] like figure 1 , figure 2 As shown, a method for measuring the airtightness of a square-shell cell forming equipment includes the following steps:
[0021] S1: Put the restraint fixture installed on the square cell into the formation testing equipment;
[0022] S2: Click the formation plugging measurement software on the formation detection equipment to start plugging detection;
[0023] S3: In step S3, the plugging detection software is used to start plugging detection, and the plugging detection software detects whether the press is in the open state, and if it is not, send a command to the press to perform the opening operation;
[0024] S4: If it is in the open state, the formation plugging measurement software will issue a command to close the micro positive pressure and low vacuum, open the high vacuum command to the press to perform ...

The invention discloses a method for detecting air tightness blockage of square-shell battery cell formation equipment. The method comprises the following steps that a restraining jig which is arranged in a square battery cell is mounted into formation detection equipment; formation blockage detection software on the formation detection equipment is clicked to start blockage detection; the formation blockage detection software in the step S3 starts blockage detection, and the formation blockage detection software detects whether a press is in an open state or not; when the formation blockage measurement software collects a current negative pressure value from the press, if the collected negative pressure value is higher than a preset standard value, it is considered that the suction nozzle of the press is blocked, blockage detection is not qualified, and execution is not carried out any more; when the formation blockage detection software issues a high vacuum closing instruction to the press and then issues a low vacuum opening instruction to the press, low vacuum pumping operation is executed, and waiting is performed for a period of time; and the formation blockage detection software acquires the current negative pressure value from the press. The method has the beneficial effects that the blockage can be automatically tested before the battery is tested, the consumed time is short, other additional hardware does not need to be added, the test is prevented from being continued due to blockage or air leakage of the press suction nozzle, the yield is reduced, and the production cost is increased.
