By arranging the above arrangement, the plurality of helium detection trays 110 are displaced along the switching track 120, so that the switching displacement of the plurality of helium detection trays 110 on the loading and unloading stations and the helium detection stations is realized, and when one helium detection tray 110 performs the loading and unloading processes, the other helium detection tray 110 performs the helium detection process, thereby improving the working efficiency of helium detection.

As shown in fig. 5 to 6, the switching driving assembly 130 includes a switching driving member 131 and a switching connecting member 133, wherein the switching driving member 131 has a switching portion 132, and when the switching driving member 131 works, the switching portion 132 can be displaced along the switching track 120, specifically, the switching driving assembly 130 can be configured as a linear motor (of course, also can be configured as a cylinder or a hydraulic cylinder), and the switching portion 132 is a platform capable of being displaced under the driving of the linear motor; the switching connector 133 is disposed at the switching portion 132 and is capable of following the displacement of the switching portion 132 along the switching track 120, and the connection and disconnection of the switching drive assembly 130 and the helium test tray 110 are realized by the connection and disconnection of the switching connector 133 and the helium test tray 110.

Since the helium test trays 110 are provided with a plurality of switching connectors 133 which can be connected with and disconnected from any one of the helium test trays 110, the switching driving assembly 130 can drive any one of the helium test trays 110 to move along the switching track 120, and thus, any one of the plurality of helium test trays 110 can be independently driven by one switching driving assembly 130, which is beneficial to saving driving cost.

Of course, multiple helium test trays 110 may also be individually driven by multiple switching drive assemblies 130.

Specifically, the switching connector 133 is provided with a telescopic pin 134, the helium detection tray 110 is provided with a pin hole, the pin hole is matched with the telescopic pin 134, when the helium detection tray 110 is at a corresponding station, the telescopic pin 134 can extend into and extend out of the pin hole, and then connection and disconnection of the switching connector 133 and the helium detection tray 110 are achieved, namely, when the telescopic pin 134 is located in the pin hole, the switching connector 133 can drive the helium detection tray 110 to move along the switching track 120, and when the telescopic pin 134 is located outside the pin hole, the switching connector 133 cannot drive the helium detection tray 110 to move along the switching track 120. In this way, the connection and disconnection operation of the switching connector 133 and the helium test tray 110 is realized by the telescopic displacement of the telescopic pin 134, so that the control is convenient, and the cost is saved.

It should be noted that, the telescopic direction of the telescopic pin 134 forms an angle with the displacement direction of the helium test tray 110, and the angle is preferably 90 degrees, so as to form an obstruction in the displacement direction of the helium test tray 110 and drive the helium test tray 110 to displace.

Here, the switching connector 133 may be provided as an air cylinder or a hydraulic cylinder, and the telescopic pin 134 may be provided as a telescopic end thereof, and of course, may be provided as a form of engagement of the motor with the screw nut mechanism.

As shown in fig. 2, the helium detector comprises a helium rechecking mechanism 7, a reject conveying line 8 and a transferring mechanism 9. The helium rechecking mechanism 7 is similar to rechecking the product, and after the first helium test is finished, if an unqualified product appears, the product needs to be subjected to a second helium test through the helium rechecking mechanism 7, or the qualified product is subjected to the second helium test, so that the accuracy of the helium test is ensured; the reject conveying line 8 is used for conveying unqualified products after the helium rechecking mechanism 7 rechecks so as to reject the unqualified products, and can be in a transmission belt form or a double-speed chain form; the transfer mechanism 9 is used for transferring the product between the product transfer line (i.e., the second transfer line located downstream of the helium detection tray), the helium detection and rechecking mechanism 7 and the reject transfer line 8 to realize the transfer of the product between the second transfer line 200, the helium detection and rechecking mechanism 7 and the reject transfer line 8, and in particular, the transfer mechanism 9 may be provided as a robot structure.

In combination with the scheme that the helium test tray 110 carries a plurality of products simultaneously for helium test, after the products in the same batch are subjected to helium test on the helium test tray 110, if any one of the products in the batch is failed, the products in the batch are marked as failed, and the products in the batch are required to be subjected to re-test screening through the helium test re-test mechanism 7 so as to sort out the qualified products and the unqualified products in the same batch, wherein a specific sorting re-test mode can be set as a one-by-one re-test mode, and the re-test can also be performed through a dichotomy.

For example, n products exist in the same batch, the n products are equally divided into two groups (1/2 n products in each group) during the re-inspection, the qualified group is transferred to the second conveying line 200 for discharging, the unqualified group is equally divided into two groups (1/4 n products in each group) again, the qualified group is transferred to the second conveying line 200 for discharging again, the unqualified group continues to be equally divided for re-inspection, and so on until all unqualified products are separated out, and the unqualified products are subjected to waste removal conveying through the waste removal conveying line 8, so that the re-inspection times can be reduced by adopting a bisection method.

Therefore, through the cooperation of the helium detection and rechecking mechanism 7, the reject conveying line 8 and the transfer mechanism 9, the second helium detection of the product can be realized, the accuracy of helium detection is improved, and the qualified product and the unqualified product can be sorted, so that the separate conveying of the qualified product and the unqualified product is realized, and the follow-up blanking products are guaranteed to be qualified products.

Further, the reject conveyor line 8 and the helium test re-inspection mechanism 7 are located on both sides of the product conveyor line (i.e., the second conveyor line 200 located downstream of the helium test tray), respectively. Like this, when transport mechanism 9 transports the product, can reduce transport mechanism 9's transport distance, through shorter transport route, and then promote work efficiency.
