And because the detection method is also provided with a cleaning step, the detection method is more convenient for automatic application.

Example one

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a method for detecting the integrity of a product seal according to an embodiment of the present invention. The execution main body of the method described in the embodiment of the present invention is an execution main body composed of software or/and hardware, and the execution main body can receive related information in a wired or/and wireless manner and can send a certain instruction. Of course, it may also have certain processing and storage functions. The execution body may control a plurality of devices, such as a remote physical server or a cloud server and related software, or may be a local host or a server and related software for performing related operations on a device installed somewhere. In some scenarios, multiple storage devices may also be controlled, which may be co-located with the device or located in a different location. As shown in fig. 1, the method for detecting the sealing integrity of a product comprises the following steps:

s101: the control solenoid valve assembly is in a first state, which comprises the first solenoid valve 5 being open and the second 6, third 7 and fourth 8 solenoid valves being controlled to be closed;

at the beginning, the state of each electromagnetic valve component is in a closed state; when the tightness of a product needs to be detected, the state of the switching solenoid valve assembly needs to be controlled; the scheme of the embodiment of the invention mainly aims at products which can volatilize organic matters, such as lithium batteries or chemical products or pharmaceutical products and the like; when the product is not tightly sealed, the organic volatile matter can overflow, namely leakage is generated; if the leakage of the products is more, the actual use of the products is greatly influenced; if the lithium battery has liquid leakage, the electricity safety is greatly influenced; this process needs to be checked.

S102: controlling and starting a vacuumizing device to vacuumize the detection cavity until the pressure value in the detection cavity reaches a set value;

when the electromagnetic valve component is switched to the first state, only the vacuumizing channel and the detection cavity are in a communicated state, and because the product to be detected is placed into the detection cavity in advance, the vacuumizing device is controlled to be started to vacuumize the detection cavity; the detection cavity is in a vacuum detection state, and if the product to be detected has cracks or is not sealed tightly, substances in the product to be detected can be separated out and enter the detection cavity due to the fact that the detection cavity is in the vacuum state, namely, the air pressure is relatively low. When carrying out concrete pressure setting, can be with the vacuum setting in the detection cavity relatively lower, can be better seal the detection like this.

When the vacuum degree in the detection cavity reaches a set value, the detection cavity is controlled to be started for pressure maintaining, so that the pressure in the detection cavity can be maintained for a certain time, and the leakage and precipitation of the product to be detected are more complete; when the detection is carried out specifically, the detection cavity can be heated to accelerate the precipitation of VOC substances.

S103: the control solenoid valve assembly is in a second state comprising the first solenoid valve 5 closed, the second solenoid valve 6 and the third solenoid valve 7 open;

when the time of the product to be detected in the detection cavity reaches the set time, the VOC substance of the product to be detected is volatilized relatively completely; at the moment, specific concentration detection can be carried out, and the switching electromagnetic valve assembly is controlled to be in the second state; specifically, the first electromagnetic valve 5 is controlled to be closed, the second electromagnetic valve 6 and the third electromagnetic valve 7 are controlled to be opened, the fourth electromagnetic valve 8 is subjected to proportion adjustment, and sampling pressure is built through the above steps, so that air at the detection cavity flows and is exhausted through an exhaust passage; in the specific implementation, the second solenoid valve 6 also uses a proportional regulating valve for pressure regulation.

S104: and controlling the starting gas source device to work so as to blow the gas separated out from the detection cavity into the detection channel for corresponding gas detection.

In the embodiment of the invention, nitrogen or clean air is injected through an air source device, so that the gas separated out from the detection cavity is driven to enter a subsequent detection channel; in the embodiment of the invention, the air source device performs active air blowing, and during specific implementation, the flow sensor arranged at the blowing pipeline 2 is used for performing real-time flow monitoring to ensure the dilution ratio. The gas blown in the embodiment of the invention can carry out uniform concentration on the VOC volatile matter on one hand, and prevent the nonuniform concentration distribution caused by local aggregation. Because if the step of blowing by an air source device is not set, leakage with the same size occurs at different positions, and the final detection result is different due to the reason of the position where the leakage occurs because the concentration distribution is uneven and the active air flow is not performed; for example, an already unqualified leak occurs near the VOC tester, although no active air is blown in, due to a certain pressure difference, the air flows into the VOC tester to realize corresponding gas detection, which can be detected more accurately; however, an already unacceptable leak occurs at a location remote from the VOC tester, and if the controlled concentration gas is not actively blown in, the concentration obtained at the VOC tester will be too small, resulting in erroneous judgment.

In specific implementation, there is another way to avoid the influence on the detection result caused by the position; although different positions generate different leakage, if the time for performing the VOC substance precipitation in the vacuum environment is long enough, the effect of uniform air mixing can be achieved; however, the method takes a long time, which improves the accuracy of detection but reduces the detection efficiency. The embodiment of the invention can improve the detection accuracy by means of air source ventilation on the premise of ensuring the detection efficiency.

More preferably, the control start air supply device works and comprises:

When the specific air flow control is carried out, two modes are available, one mode is that air is blown in according to a constant flow rate, and for the mode, the output of an air source device is relatively easy to control, and the air with the constant flow rate can be directly controlled and output; however, the situation that the output flow rate of the air supply device is not too large can be continuously changed at the exhaust end, so that the final result can generate corresponding fluctuation, and the VOC detection instrument at the rear end can perform accurate detection as long as the output flow rate of the air supply device is not too large. The other method is to adjust the amount of air blown in the air source by detecting the amount of air in real time through a flow sensor, and the mode is to ensure the stability of the air flow exhausted by the exhaust end and facilitate the detection of the concentration by a VOC detection instrument. In the other method, air is blown in according to a preset flow curve, because data of all aspects are constantly changed in the air flowing process, a large amount of flow output data of all aspects in the process to be detected are obtained in advance, and then a flow control curve is obtained to finally control the blowing of the air source according to the flow control curve.

More preferably, the method further comprises:

When the numerical value detected by the VOC detector exceeds the alarm value, the alarm value can also judge that the leakage quantity of the product to be detected exceeds the standard; the specific alarm operation comprises the steps of sounding a buzzer, lighting an indicator lamp or reminding information and the like, and the purpose is to remind a user of a product to be detected with leakage exceeding the standard. In order to realize better automatic processing, the embodiment of the invention is also provided with a cleaning step for cleaning residues in the detection cavity and the detection channel; particularly when a VOC leak is detected in the last product, cleaning must be performed. The specific cleaning step is to introduce nitrogen or clean air into the detection cavity and the detection channel, and then to perform vacuum pumping operation, so that the final cleaning is more thorough. More preferably, cleaning is performed once after each detection, so as to prevent certain errors of subsequent detection caused by continuous accumulation of the VOC.

More preferably, fig. 3 is a schematic flow chart of calibration data acquisition disclosed in the embodiment of the present invention, and as shown in fig. 3, the gas detection apparatus performs data calibration by the following steps:

carrying out sealing integrity detection on unqualified products;

In the embodiment of the invention, in order to carry out more accurate detection, the data needs to be calibrated in advance; since this time corresponding air is blown in, the concentration at the time of the specific test is lower than usual, and therefore, in order to perform more accurate measurement, a prior leak calibration is required. In the process, a large number of unqualified products need to be obtained, and then data calibration detection is carried out on the unqualified products; during the detection, the output flow of the air source can be correspondingly adjusted, because if the output gas of the air source is too large, the concentration is too small, and thus the false detection condition is easily generated during the subsequent detection; therefore, when the specific design is carried out, products with different leakage amounts are detected and calibrated, and then more comprehensive data are obtained. In the event that the flow rate is determined, then different concentration data can be detected, and the concentration data can then be correlated with the orifice size, such that the user can determine the current orifice size after subsequent detection of the corresponding VOC concentration. On the premise of ensuring uniform concentration, the same amount of leakage is generated at different leakage positions, and the concentration of VOC substances volatilized from the leakage hole and the excrement and urine of the leakage hole have a corresponding relation. The method for controlling the concentration and uniformity of active blowing can improve the repeatability consistency of the test, ensure that the measured data can truly reflect the size of the leakage hole (the size of leakage) and further ensure that the collected data can be transversely compared, and further provide fine information for quality control, process improvement and the like.

The method for detecting the sealing integrity of the product ensures the dilution ratio of the product finally entering the detection pipeline 4 by controlling the amount of gas blown in by the gas source device, and the concentration of the volatile organic compounds is more uniform by adopting the active blowing mode of the gas source device, so that the gas detection instrument can perform more stable detection, the probability of false detection is reduced, and the detection method is more convenient for automatic application due to the cleaning step.
