The traditional back contact battery piece welding equipment has the defect that a large number of welding strip material rolls need to be arranged, and the cost of the welding equipment is increased.
The traditional back contact battery piece welding equipment has the defect that a large number of welding strip material rolls need to be arranged, and the cost of the welding equipment is increased.
In view of this, the utility model provides a battery cluster welding equipment and welding method to only set up a welding strip coil group, can weld back of the body contact formula battery piece (hereinafter simply referred to as "battery piece") into the cluster. The battery string welding apparatus and the welding method according to the present invention will be described below by way of two exemplary embodiments, respectively.
As shown in fig. 3 to 5, the battery string welding apparatus provided in this embodiment includes a welding conveying device 10, a battery sheet laying device 20, a welding strip processing device 30, a welding strip pulling device 40, and a welding device 50, wherein:
the welding conveyor 10 is used for conveying the battery piece and the solder ribbon assembly in a first horizontal direction (e.g., the X-axis direction in fig. 1).
The cell placement device 20 is used for placing the N cells on the welding conveyor 10 with the back surfaces facing upward in the first horizontal direction, and the polarities of the electrode rows of the adjacent cells in the same line are opposite.
The solder strip handling apparatus 30 is configured to clamp a plurality of solder strips extending in a first horizontal direction, and drive the solder strips to move in a second horizontal direction (e.g., a Y-axis direction in fig. 1) perpendicular to the first horizontal direction, so as to switch positions of the solder strips between a first solder strip group feeding station and a second solder strip group feeding station, and cut off the solder strips at the first solder strip group feeding station and the second solder strip group feeding station to obtain a solder strip group. For example, the solder ribbon cut at the first solder ribbon group feeding station is an odd number of solder ribbon groups, and the solder ribbon cut at the second solder ribbon group feeding station is an even number of solder ribbon groups.
And the welding strip traction device 40 is used for drawing the welding strip group at the first welding strip group feeding station and stacking the welding strip group on the welding conveying device corresponding to the odd-numbered electrode row of the battery piece, and drawing the welding strip group at the second welding strip group feeding station and stacking the welding strip group on the welding conveying device corresponding to the even-numbered electrode row of the battery piece. Namely, the solder strip pulling device 40 alternately obtains the odd number of solder strip groups and the even number of solder strip groups which are cut from the first solder strip group feeding station and the second solder strip group feeding station, and finishes laying the solder strip groups.
The welding device 50 is used for welding the stacked ribbon assembly and the battery pieces into a string.
It can be seen that the battery string welding equipment in the embodiment realizes welding string of back-to-back contact type battery pieces by matching the welding conveying device 10, the battery piece laying device 20, the welding strip processing device 30, the welding strip traction device 40 and the welding device 50.
Particularly, the solder strip processing device 30 in this embodiment can drive the solder strips to move between the first solder strip group feeding station and the second solder strip group feeding station, so as to ensure that the solder strip pulling device 40 can alternately obtain the odd number of solder strip groups and the even number of solder strip groups from the first solder strip group feeding station and the second solder strip group feeding station, and alternately lay the odd number of solder strip groups and the even number of solder strip groups on the battery piece.
Therefore, only one welding strip coil group is needed to be arranged, and welding strips with the quantity being half of that of electrode rows on the battery piece are discharged, so that alternate feeding of odd-numbered welding strip groups and even-numbered welding strip groups can be completed. Thereby greatly reducing the cost of the welding equipment.

That is, when the solder ribbon clamping mechanism 31 moves the solder ribbon to the first solder ribbon group feeding station, the first cutting execution part performs the cutting action, thereby obtaining an odd number of solder ribbon groups. And when the solder strip clamping mechanism 31 moves the solder strip to the second solder strip group feeding station, the second cutting executing part executes the cutting action, thereby obtaining the even number of solder strip groups.
The third setting mode is as follows:

In this way, when the solder strip clamping mechanism 31 moves the solder strip to the first solder strip group feeding station, the cutting execution part executes the cutting action, the part of the cutting execution part located at the first solder strip group feeding station cuts the solder strip to obtain the odd number of solder strip groups, and the part of the cutting execution part located at the second solder strip group feeding station is cut in an idle manner. When the solder strip clamping mechanism 31 moves the solder strip to the second solder strip group feeding station, the cutting executing part executes the cutting action, the part of the cutting executing part, which is positioned at the second solder strip group feeding station, cuts the solder strip to obtain the even number of solder strip groups, and the part of the cutting executing part, which is positioned at the first solder strip group feeding station, is free-cut.

In this embodiment, the total number of the material trays in the solder strip unwinding device is half of the number of the electrode rows on the battery piece. For example, 18 electrode rows are provided on the cell sheet shown in fig. 1. Correspondingly, 9 material rolls are arranged in the solder strip unwinding device in this embodiment, so that 9 solder strips can be simultaneously paid out by the solder strip unwinding device, and each odd number of solder strip groups and even number of solder strip groups obtained after being processed by the solder strip processing device 30 include 9 solder strip sections.
