Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell processing equipment, and in particular to cell film coating tooling and systems. Background Art

[0002] As the cost reduction route of components continues, the development of busbar-free components has become imperative, and the lamination process is one of the interconnection technologies. The lamination process mainly covers the carrier film on the battery cell and the soldering strip, and uses the adhesive force of the carrier film softened by heat to attach to the battery cell to fix the soldering strip, thereby completing the interconnection of the battery string.

[0003] In the prior art, the coating is heated by two methods: infrared lamp heating (front) and hot air blowing (back). When heating by infrared lamps, the tooling press must have a certain hollow area to ensure that the battery cell or the carrier film is heated. However, the hollow area will cause the carrier film and the battery cell to not fit well due to the problem of no direct pressure from the tooling. The poor fitting will indirectly lead to poor contact between the soldering tape and the battery cell, which will increase the probability of aging failure after the component packaging lamination, seriously affecting the service life of the battery cell assembly. When the conventional tooling (pressing needle) presses down the carrier film, the straightness of the carrier film is small, which makes the tension of the carrier film covering the soldering tape small, thus affecting the quality of the coating, and also increases the probability of aging failure of the battery cell assembly, so as to affect the service life of the battery cell assembly. Utility Model Content

[0004] Based on this, it is necessary to provide a battery cell coating tool and system to address the problem that the coating process in the prior art may affect the contact between the welding point and the battery cell, or affect the quality of the coating, thereby increasing the probability of aging and failure of the battery cell assembly, and thus affecting the service life of the battery cell assembly.

At this time, the carrier film between the welding strip and the battery cell is flat and tight. The above-mentioned battery cell laminating tooling makes the carrier film flatly attached to the battery cell.

Multiple welding strips are located between the carrying film and the battery cell and extend along the second direction. Multiple welding strips are arranged along the third direction, and each welding strip is located between two adjacent two-shaped holes. The side of the first pressure plate facing away from the second pressure plate abuts against the carrying film and is fixed relative to the carrying part, and the heating part is connected to the second pressure plate. Since the side of the first pressing plate facing away from the second pressing plate abuts against the carrier film, the carrier film is located between the first pressing plate and the battery cell. The carrier film abuts against the welding strip, and the welding strip is placed on the side of the battery cell close to the first pressing plate, so the welding strip is clamped between the first pressing plate and the battery cell. Since the carrier film is in a tight state and has a certain tension when the convex strip does not contact the carrier film, the second pressing plate is moved along the first direction to make the convex strip close to the carrier film, the convex strip abuts against the carrier film and makes the carrier film close to the battery cell.

A plurality of welding strips 230 are arranged along the third direction OZ, and each welding strip 230 is located between two adjacent strip holes 111. The side of the first pressing plate 110 away from the second pressing plate 120 abuts against the carrying film 220 and is fixed relative to the carrying part, and the heating part is connected to the second pressing plate 120. Since the side of the first pressing plate 110 facing away from the second pressing plate 120 abuts against the carrier film 220, the carrier film 220 is located between the first pressing plate 110 and the battery cell 210. The carrier film 220 abuts against the soldering tape 230, and the soldering tape 230 is placed on the side of the battery cell 210 close to the first pressing plate 110. Therefore, the soldering tape 230 is clamped between the first pressing plate 110 and the battery cell 210. When the convex strip 121 does not contact the carrier film 220, the carrier film 220 is in a tight state and has a certain tension, such as Figure 2 and 3Therefore, the second pressing plate 120 is moved along the first direction OX to make the convex strip 121 close to the carrier film 220, the convex strip 121 abuts against the carrier film 220 and makes the carrier film 220 close to the battery cell 210, the heating part is used to heat the convex strip 121, the convex strip 121 abuts against the carrier film 220 so that the carrier film 220 is softened by heat, and under the action of tension, it is always flat and wrinkle-free until it is pushed onto the battery cell 210 by the convex strip 121 and flatly attached to the battery cell 210. At this time, the carrier film 220 between the welding ribbon 230 and the battery cell 210 is flat and tight, as shown in FIG. Figure 4 and 5 The above-mentioned cell film laminating tool 100 allows the carrier film 220 to be evenly attached to the cell 210 .

The plurality of strip-shaped through grooves 140 extend along the second direction OY, and the plurality of strip-shaped through grooves 140 in each group of pressing needles 130 have the same axis along the second direction OY. In this embodiment, the welding strip 230 is limited by a plurality of protrusions abutting against the welding strip 230, and each protrusion limits the welding strip 230 through the inner wall of the strip-shaped through groove 140 on the protrusion, and ensures that the welding strip 230 extends along the second direction OY, so that the pre-fixation of the welding strip 230 is more stable.

[0052] In another embodiment, each group of pressure needles 130 is an abutment bar (not shown), the abutment bar extends along the second direction OY, and each abutment bar is provided with a strip groove 141 along the second direction OY, and the inner wall of the strip groove 141 is used to abut with the welding strip 230.

Compared with the form of multiple protrusions, the pre-fixation of the welding strip 230 is more stable.

[0053] See also Figure 3 and Figure 5 In one embodiment, the strip groove 141 and the strip through groove 140 are both arc grooves, and the inner wall of the arc groove is adapted to the side wall of the welding strip 230, so that the inner wall of the arc groove abuts against the side wall of the welding strip 230, thereby improving the stability of the pre-fixation of the welding strip 230, and reducing the Figure 5 The angle between the carrier film 220 and the battery cell 210 is shown so that the carrier film 220 is closer to the battery cell 210 , thereby increasing the service life of the carrier film 220 .

[0054] See also Figure 1 In one embodiment, chamfers 122 are provided on both sides of the convex strip 121 along the third direction OZ, so that the convex strip 121 is easier to insert into the strip-shaped hole 111.

[0056] In one embodiment, the battery cell coating tool 100 also includes two fixing parts (not shown), and the two fixing parts correspond to the two fixing holes 112 one by one. The fixing parts are inserted into the fixing holes 112 to fix the first pressing plate 110, so that the first pressing plate 110 can be fixed relative to the bearing part, so that during the operation of the second pressing plate 120, the battery cell 210, the bearing film 220, and the welding strip 230 can be relatively fixed, thereby improving the coating quality.

[0057] Specifically, the fixing member is a connecting member such as a screw or a bolt, or may be a magnetic member, which fixes the first pressing plate 110 and the bearing part relatively by magnetic force.

[0058] See also Figure 1An embodiment of the present application provides a battery cell 210 coating system for attaching a carrier film 220 to a battery cell 210 .

Therefore, the soldering tape 230 is clamped between the first pressing plate 110 and the battery cell 210. When the convex strip 121 does not contact the carrier film 220, the carrier film 220 is in a tight state and has a certain tension, such as Figure 2 and 3 Therefore, the second pressing plate 120 is moved along the first direction OX to make the convex strip 121 close to the carrier film 220, the convex strip 121 abuts against the carrier film 220 and makes the carrier film 220 close to the battery cell 210, the heating part is used to heat the convex strip 121, the convex strip 121 abuts against the carrier film 220 so that the carrier film 220 is softened by heat, and under the action of tension, it is always flat and wrinkle-free until it is pushed onto the battery cell 210 by the convex strip 121 and flatly attached to the battery cell 210.

Figure 4 and 5 The above-mentioned cell film laminating tool 100 allows the carrier film 220 to be evenly attached to the cell 210 . Since the carrier film 220 is flat and wrinkle-free during the entire attaching process, the attaching quality is high, and there are no bubbles or other unattached areas, thereby improving the quality of the cell 210 .
