Optionally, the series welding machine further comprises a material box arranged at the input end of the conveying device and used for storing the battery pieces, or a conveying line used for conveying the battery pieces from the previous procedure, such as conveying the battery pieces after being broken off from the piece breaking device.
In one possible implementation manner, in order to improve welding efficiency, the stringer may weld a longer welding strip between the battery strings, and then cut the longer welding strip in the subsequent step so as to separate the two battery strings, for this purpose, the stringer provided by the application may further include a string separating device disposed in the subsequent step of the welding device, so as to perform string separating processing on the battery strings obtained by welding by the welding device, and obtain a battery string with a predetermined length.
The battery string of a predetermined length is a battery string having a predetermined number of battery pieces connected.
Generally, the number of each battery string is industry or manufacturer required, such as 6 battery cells connected to form one battery string, or 10 battery cells connected to form one battery string, etc. When the battery string is generated, the front half part of the first set of welding strips with a preset length is welded on the front main grid line of the first battery piece, and the rear half part of the set of welding strips is welded on the rear main grid line of the second battery piece, so that the first battery piece and the second battery piece are connected in series by using the set of welding strips. Similarly, a front half portion of a second set of solder strips of a predetermined length is soldered to the front main grid line of the second cell, and a rear half portion of the set of solder strips is soldered to the rear main grid line of the third cell, so that the second cell and the third cell are connected in series by the set of solder strips. And so on.
The end of each battery string needs to be welded with a bus bar for collecting the current of a plurality of battery strings, and the length of the welding strip used for welding the bus bar at the end is smaller than that of the welding strip of the non-end part of the battery string because the welding strip at the end is only connected with one battery piece at the end, so that after each battery string is welded in the traditional production line of the battery strings, a short welding strip is cut for being welded to the head end part of the next battery string, and then a short welding strip is welded at the tail end part of the battery string. Such beats require a large distance between battery strings, i.e., a certain length of time is waited between the two battery strings, resulting in a relatively low production efficiency.
To this, the string welding machine in this application can weld a longer welding strip (avoid the damage to battery string tip battery piece when dividing the cluster) between battery string and battery string when generating the battery string, then utilize the branch cluster device to cut longer welding strip between battery string and the battery string, whole production beat can not wait for longer time between the battery string, and production efficiency is higher.
In practical application, the separation device can be a separation cutter, namely an upper cutter and a lower cutter which are arranged up and down oppositely, and then the upper cutter and the lower cutter are driven by a driving device to perform relative movement so as to cut a welding strip between the upper cutter and the lower cutter. Because of the need for a string-splitting knife to cut, the length of the solder strip between two adjacent strings is generally greater than the length of the solder strip that connects two adjacent battery cells in a string, in order to avoid damage to the ends of the string.
And the welded battery strings are subjected to string separation by using the string separation device, so that the battery strings with the preset length are obtained, the waiting time period between two adjacent battery strings in the welding process is avoided, and the generation beat is improved.
In one possible implementation, in order to improve welding efficiency, the stringer provided herein may further include a flux spraying device disposed in a front path of the welding device, where the flux spraying device sprays flux onto the battery piece, or sprays flux onto the solder strip, or sprays flux onto both the solder strip and the battery piece. In this way, the soldering quality and efficiency are improved by using the soldering flux spraying device to spray soldering flux to the battery piece and/or the soldering ribbon.
In summary, when the stringer is implemented, the battery piece feeding part and the tooling carrying part are arranged on the carrying device of the carrying robot, and the battery piece and the tooling are carried by using one carrying device, so that the space occupation of the carrying device is reduced; the welding device is used for realizing the welding between the stacked battery pieces and the welding strips.
