It should be noted that when the detecting structure detect it is described absorption connector 6 be not aligned with the battery pack 8 when, then institute
Stating controller will control the driving retractor device to work, and the driving retractor device drives the telescopic arm elongation or received
Contracting, the absorption connector 6 is set to be directed at the battery pack 8.
The operation principle of the present embodiment is that the battery pack 8 is arranged in the position limiting structure, and the fixing device will
The support of the battery pack 8 is fixed.The detecting structure detects the battery pack 8 and is placed on the position limiting structure
In, the detecting structure gives the information transfer detected to the controller, the controller control absorption mobile device 4
Mobile terminal move down, when the position that the absorption connector 6 movement on the mobile terminal of the absorption mobile device 4 is suitable
When upper, the controller controls the work of the vacuum extractor, and the suction nozzle 7 holds the other end of the battery.
Then the mobile terminal of the controller control absorption mobile device 4 moves up, i.e., the described mobile dress of absorption
Put 4 and pull the battery to the direction away from the conducting strip in the presence of predetermined pull, the battery can be in the branch
Moved in frame.When one end of the battery does not depart from the electrode, i.e., described battery is in the presence of pulling force not in the branch
Moved in frame, then prove that the welding battery intensity meets welding standard, not rosin joint, and firm welding be present.When the electricity
The one end in pond departs from the electrode, i.e., described battery moves in the presence of pulling force in the support, it was demonstrated that the battery
Weld strength is unsatisfactory for welding standard, phenomena such as rosin joint or solid not prison welding be present.The predetermined pull of each battery is
49 newton, that is to say, that each suction nozzle 7 is 49 newton to the pulling force of the battery.
For the present invention as a result of the absorption mobile device and the suction nozzle, the suction nozzle is arranged on the absorption movement
On the mobile terminal of device, the suction nozzle holds the other end of the battery, work of the absorption mobile device in constant force
The battery is pulled to the direction away from the conducting strip with lower, if one end of the battery does not depart from the electrode,
Prove that the welding battery intensity meets welding standard, otherwise prove that the welding battery intensity is unsatisfactory for welding standard, with showing
There is technology to compare, tensions constant, and also the quantity of the suction nozzle can be identical with the quantity of the battery, so described detection dress
Put the weld strength that disposable can detects some batteries and the electrode, have easy to detect, detection efficiency high and
The advantages that electrode will not be damaged.
It should be noted that explaining in detail for the respective embodiments described above, its purpose is only that to be solved to the present invention
Release, in order to be able to preferably explain the present invention, still, these description can not with any explanation into be to the present invention limit
System, particularly, each feature described in various embodiments can also be mutually combined, so as to form other implementations
Mode, except there is clearly opposite description, these features should be understood to be applied in any one embodiment, and simultaneously
It is not only limited to described embodiment.
