As shown in fig. 4, the first surface and the second surface of a cell sheet (hereinafter, may be referred to as a cell sheet) 100 without a main grid line to be connected in series according to the present invention are only provided with a plurality of mutually parallel sub grid lines 101 for collecting current. The first surface is the front surface of the battery piece, and the second surface is the back surface of the battery piece, or the first surface is the back surface of the battery piece, and the second surface is the front surface of the battery piece.
The battery piece stringing device and the battery piece stringing method provided by the invention are respectively exemplified by two embodiments.
First embodiment
As shown in fig. 1 to fig. 3, the cell stringing device provided in this embodiment includes a cell gluing mechanism 10, a cell stacking mechanism 20, a solder ribbon stacking mechanism 30, and a conveying mechanism 40, wherein:
the cell gluing mechanism 10 is configured to apply an insulating glue to the first surface and the second surface of the cell 100 in the region between each adjacent pair of grid lines.
In order to save the insulating glue and reduce the pollution of the insulating glue to the battery piece, optionally, as shown in fig. 5, the battery piece glue coating mechanism 10 coats a predetermined number (e.g., six in fig. 5) of dot-shaped insulating glues 200 in the region between each two adjacent sub-grid lines 101 in an intermittent glue dispensing manner along the extending direction of the sub-grid lines 101, and ensures that the dot-shaped insulating glues 200 at corresponding positions in different regions are located on the same serial connection line L, where the serial connection line L is perpendicular to the sub-grid lines 101.
Of course, in consideration of the gluing efficiency, the glue may be applied in a continuous manner along the extending direction of the sub-gate lines 101, so that a continuous linear insulating glue is applied in the region between each adjacent sub-gate lines 101.
The cell stacking mechanism 20 and the solder ribbon stacking mechanism 30 are configured to stack the glued cell 100 and the solder ribbon group on the conveying mechanism 40 to form a cell string, wherein, as shown in fig. 6, a first half section of the ith group of solder ribbons is adhered to a first surface (such as the front surface) of the ith cell through insulating glue and perpendicularly intersects all the sub-grid lines on the first surface, a second half section of the ith group of solder ribbons is adhered to a second surface (such as the back surface) of the (i + 1) th cell through insulating glue and perpendicularly intersects all the sub-grid lines on the second surface, and i is an integer greater than or equal to 1.
Of course, the head end and the tail end of the battery string are respectively adhered with a head welding strip group and a tail welding strip group.
As shown in fig. 5 and 7, six dot-shaped insulating glues 200 are coated in the region between each adjacent pair of grid lines 101, that is, six series lines L are formed on each of the first and second surfaces of the battery cell 100. Accordingly, each set of solder strips includes six solder strips 300, and each solder strip 300 is adhered to one of the series lines L.
Therefore, through the cooperation of the cell gluing mechanism 10, the cell stacking mechanism 20, the solder strip stacking mechanism 30 and the conveying mechanism 40, the cell stringing device provided by the embodiment of the invention realizes stringing of cells without main grid lines.
As shown in fig. 1, optionally, the cell glue coating mechanism 10 includes a cell feeding mechanism (not shown), a glue coating conveying mechanism 11 and a glue coating assembly 12, wherein: the battery piece feeding mechanism is used for feeding the battery pieces to the gluing conveying mechanism 11. The gluing conveying mechanism 11 is used for conveying the battery piece to the gluing component 12. The gluing assembly 12 is used for applying insulating glue to the first surface and the second surface of the battery piece in the area between each adjacent secondary grid line.
Optionally, as shown in fig. 1 and fig. 2, the cell glue coating mechanism 10 further includes a cell turnover mechanism 13 disposed on the glue coating and conveying mechanism 11, and the cell turnover mechanism 13 is configured to turn over the cell 100. For example, when the battery sheet feeding mechanism feeds the battery sheet 100 onto the glue coating and conveying mechanism 11, a first surface (e.g., front surface) of the battery sheet 100 faces upward, and after the battery sheet turning mechanism 13 turns over, a second surface (e.g., back surface) of the battery sheet 100 faces toward.
In the embodiment shown in fig. 1 and 2, two groups of gluing assemblies 12 are provided, and both groups of gluing assemblies 12 are arranged above the gluing conveyor 11. Wherein, one group of glue coating assemblies 12 in the front row applies the insulating glue to the first surface of the battery piece before the battery piece 100 is turned over, and the other group of glue coating assemblies 12 in the rear row applies the insulating glue to the second surface of the battery piece 100 after the battery piece 100 is turned over.
Of course, it is also possible to arrange both sets of gluing components 12 below the gluing conveying mechanism 11, and the two sets of gluing components 12 apply the insulating glue to both surfaces of the battery piece 100 from below one after another.
In order to enable the glue applying assembly 12 disposed below the glue applying and conveying mechanism 11 to smoothly apply the insulating glue to the battery cell, optionally, as shown in fig. 2, the glue applying and conveying mechanism 11 includes a first conveying belt 111 and a second conveying belt 112 disposed side by side, the first conveying belt 111 is used for supporting a first side edge of the battery cell 100, and the second conveying belt 112 is used for supporting a second side edge of the battery cell 100 opposite to the first side edge. In this way, the downward surface of the battery piece 100 on the glue conveying mechanism 11 can almost completely expose the glue conveying mechanism 11, so that the glue applied by the glue applying component 12 can be smoothly received.
Of course, in order to reduce the gluing cost, only one group of gluing assemblies 12 may be provided, which may be arranged above the gluing conveyor 11 or below the gluing conveyor 11. Specifically, the glue applying assembly 12 is configured to be movable in a conveying direction of the glue applying and conveying mechanism 11, and when the glue applying assembly 12 moves to a first position, the insulating glue is applied to a first surface of the battery piece, and when the glue applying assembly moves to a second position located at a subsequent stage of the first position, the insulating glue is applied to a second surface of the battery piece.
In the above gluing modes, the cell turnover mechanism 13 needs to be arranged to turn over the cell, and the gluing efficiency needs to be improved. In this regard, the glue application assemblies 12 are optionally arranged in two groups, wherein: one set of gluing components 12 is arranged above the gluing conveying mechanism 11 and is used for coating the insulating glue on the first surface of the battery piece, and the other set of gluing components 12 is arranged below the gluing conveying mechanism 11 and is used for coating the insulating glue on the second surface of the battery piece. Thus, the gluing operation on the two surfaces of the battery piece 100 can be performed without turning over the battery piece 100, so that the gluing efficiency is improved.
Of course, by adjusting the setting positions of the two groups of gluing components 12, the two groups of gluing components 12 can implement synchronous gluing of the two surfaces of the battery piece, thereby further improving the gluing efficiency.
Alternatively, a printing device or a spraying device is used as the glue spreading component 12 in the embodiment of the invention, wherein the printing device prints the insulating glue onto the battery piece in a silk-screen manner through components such as a scraper and a printing plate, and the spraying device sprays the insulating glue onto the battery piece through a high-pressure nozzle.
With continued reference to fig. 1 and 2, optionally, the cell gluing mechanism 10 further includes a first positioning mechanism 14 disposed above the gluing conveying mechanism 11 and located in a front path of the gluing assembly 12, and a second positioning mechanism 15 disposed above the gluing conveying mechanism 11 and located in a rear path of the gluing assembly 12, wherein the first positioning mechanism 14 is configured to position the cell 100 to be glued, and the second positioning mechanism 15 is configured to position the cell 100 after the gluing is completed.
The first positioning mechanism 14 performs positioning of the battery piece 100 before gluing, so as to ensure that the gluing assembly 12 can accurately apply the insulating glue to the target area of the battery piece 100. The second positioning mechanism 15 performs positioning on the battery pieces 100 after gluing, so that the battery piece 100 glued by the subsequent battery piece stacking mechanism 20 can be obtained smoothly.
Considering that the welding strip is only adhered to the battery piece through the insulating glue, the connection strength of the welding strip and the battery piece is low, and the welding strip is easy to separate. Therefore, as shown in fig. 3, optionally, the cell stringing device of the embodiment further includes a stringing mechanism 50 disposed above or below the conveying mechanism, and the stringing mechanism 50 is used for heating the cell 100, the solder strip and the insulating adhesive, so that the solder strip can be firmly adhered to the cell 100.
Optionally, as shown in fig. 3, the battery piece stringing device of the present embodiment further includes a stringing and cutting mechanism 60 disposed at the blanking end of the conveying mechanism 40, and the stringing and cutting mechanism 60 is configured to cut the battery string into a battery string with a predetermined length.
With continued reference to fig. 3, optionally, the solder ribbon stacking mechanism 30 includes a solder ribbon unreeling mechanism 31, a solder ribbon drawing mechanism 32, and a solder ribbon cutting mechanism 33, wherein: the solder strip unwinding mechanism 31 includes a mounting plate and a plurality of unwinding trays disposed on the mounting plate, each of the unwinding trays supports a roll of solder strip material and discharges a solder strip. The solder ribbon drawing mechanism 32 draws the solder ribbon paid out from each of the trays to the conveying mechanism 40 synchronously. The solder ribbon cutting mechanism 33 performs simultaneous cutting of the respective solder ribbons to perform stacking of a set of solder ribbons.

As can be seen, the method for stringing battery pieces provided by this embodiment realizes stringing operation of battery pieces without main grid lines.
Optionally, the insulating glue is coated in the area between each adjacent pair of grid lines on the first surface and the second surface of the battery piece according to the following process:
firstly, the battery piece is fed to a gluing conveying mechanism.
And then, the gluing conveying mechanism conveys the battery piece to the gluing component.
And finally, coating insulating glue on the first surface and the second surface of the battery piece in the area between the adjacent auxiliary grid lines by the glue coating assembly.
