Description

Technical Field

[0001] The utility model relates to the technical field of battery string production equipment, and in particular to a glue-applying and curing series connection equipment and production equipment applied to a battery string without a main grid. Background Art

[0002] There are two main cell stringing technologies in the prior art: the first is to apply glue on the cell to bond the soldering ribbon and the cell into a string; the second is to heat the soldering ribbon and the cell through infrared lamps to form an alloy to connect them into a string.

[0003] When the busbarless solar cells are strung together in the first way, the glue is between the solar cells and the welding strips, which may easily cause the solar cell grid lines and the welding strips to be loosely contacted, thereby making the connection resistance between the solar cells and the welding strips too large, resulting in low photovoltaic cell conversion efficiency and too high a defective rate; when the busbarless solar cells are strung together in the second way, the alloy connection strength between the welding strips and the solar cells is low, which may easily cause defects such as desoldering and cold welding, resulting in a decrease in the power of the solar cells; therefore, a glue-applying and curing series connection device and a production device for use in busbarless solar cell strings are provided, which are used to solve the problem of low connection strength of the welding strips after the busbarless solar cells are strung together.

[0051] The photographing mechanism 312 photographs the battery string 31 to mark the position, the gluing mechanism 313 applies glue twice to the solder strip of each battery cell on the front side of the battery string 31, and after applying glue, the glue is cured by the UV curing mechanism 314 to form a first-side glued battery string 32, the first-side glued battery string 32 is flipped 180 degrees by the battery string flipping assembly 320 so that its back side faces upward, the battery string transfer assembly 330 transfers the first-side glued battery string 32 with the back side facing upward to the second-side glue transfer assembly 340 for secondary gluing of the back solder strip to form a double-sided glued battery string 33, the double-sided glued battery string 33 flows into the next step, thereby completing the secondary gluing operation of the main grid-free battery string.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
