Description

Technical Field

[0001] The present invention relates to the technical field of conveying for battery cell arrangement and series welding, and in particular to a conveying device for battery cell arrangement and series welding. Background Art

[0002] As the main raw material in the processing of photovoltaic modules, the performance of solar cells directly determines the quality of photovoltaic modules. Before string welding, the solar cells need to be strictly inspected, including appearance, color difference, resistivity, and tests of parameters such as output current, output voltage and stable durability under specific light and temperature conditions. During string welding, the solar cells are taken out of the material box or silo by the automatic loading system and sent to the automatic arrangement device. The robot will automatically arrange the solar cells on the conveyor belt, ready to enter the welding process for welding.

[0003] In addition, when the battery cells are stringed together by a conventional stringing machine, because the welding head is located at one end of a conveyor belt, the arranged battery cells are moved to the welding head through the conveyor belt, and the welding head is pressed down to weld the arranged battery cells on the conveyor belt. After welding, the welded battery cells are moved out of the stringing machine through the continuous movement of the conveyor belt. However, in this process, solder often leaks onto the conveyor belt during the stringing of the battery cells by the welding head, which not only affects the cleanliness and service life of the conveyor belt, but may also have an adverse effect on subsequent processing steps.

The diameter of the removal rods 52 in this embodiment is less than or equal to the diameter of the air vent 13, and the bottom end of the removal rods 52 is arranged in an arc shape, so that the removal rods 52 can move stably along the air vent 13, and while moving, the solder at the air vent 13 is scraped off by the removal rods 52, and the removal rods 52 are used to remove impurities at the air vent 13 of the conveyor belt 1. An adjusting member 53 for adjusting the support plate 51 is installed at the top of the cleaning pool 4;

[0057] The adjusting member 53 includes a side plate 531 fixedly mounted on one side of the top of the opening of the cleaning pool 4, a servo motor 532 is mounted on the side plate 531, an output end of the servo motor 532 passes through the side plate 531 and is fixedly connected to a semi-circular disk 534, and the output end of the servo motor 532 is rotatably connected to the side plate 531;

Guide blocks 536 are fixedly installed on both sides of the support plate 51, and the swing rod 535 is rotatably connected to one of the guide blocks 536. A guide groove is provided at the guide block 536, and a guide rail 537 is slidably connected at the guide groove. The guide rail 537 is fixedly installed on the inner wall of the cleaning pool 4;

[0059] Specific implementation process: In this embodiment, the conveyor belt 1 is operated in a partitioned manner, that is, when it moves the battery cells of a module arranged thereon, it moves a certain distance relative to the stringer. For example, the moving distance is set and regulated by existing technicians, so that the battery cells at each module pass through the stringer in turn, and then pause, and the stringer welds the battery cells moved inside it. At the same time, this setting enables the conveyor belt 1 to have a fixed-length conveying characteristic. For this reason, since the air holes 13 of each column on the conveyor belt 1 in this embodiment are arranged at equal distances, each time the conveyor belt 1 moves to a section inside the cleaning pool 4, multiple columns of air holes 13 on it are synchronously moved to the air holes 13, and the setting of this example enables each corresponding air hole 13 to be located directly below the removal rod 52;

[0060] Then, the servo motor 532 is operated to make the semi-circular disk 534 rotate, and when the semi-circular disk 534 rotates, the swing rod 535 is synchronously driven to swing, and when the swing rod 535 moves, due to the limiting action of the guide blocks 536 on both sides of the support plate 51, the support plate 51 further drives the multiple removal rods 52 at its bottom to move downward, and when the removal rods 52 move downward, they synchronously pass through the air holes 13 of the conveyor belt 1 until the bottom of the support plate 51 contacts the surface of the conveyor belt 1, and the support plate 51 stops running. At this time, the bottoms of the multiple removal rods 52 are relatively located below the air holes 13.

[0061] In this example, the liquid level of the cleaning liquid inside the cleaning pool 4 is in contact with the bottom of the conveyor belt section 1 that moves into the cleaning pool 4, so that the bottom of the conveyor belt section 1 that moves into the cleaning pool 4 can be fully cleaned. In this embodiment, the cleaning liquid inside the cleaning pool 4 contains a special solder cleaning agent such as a no-clean flux or a rosin flux, so that the solder can be removed without causing damage to the conveyor belt 1.

When solder appears on the conveyor belt 1, the staff can use the external liquid supply device to supply the cleaning liquid through the liquid inlet pipe 41 into the cleaning pool 4, and at the same time ensure that the liquid level of the cleaning liquid is located at the bottom of the conveyor belt section 1 inside the cleaning pool 4 and contacts with the bottom of the conveyor belt section 1;

At this time, the conveyor belt 1 is in a paused state to ensure that the battery cells on the conveyor belt 1 are stably welded inside the stringer. At this time, a plurality of silicone cleaning brushes are respectively located between the two rows of removal rods 52, and the support plate 51 further limits the conveyor belt 1 to prevent the conveyor belt 1 from being deformed by the movement of the silicone cleaning brush.

[0068] The driving member 8 is operated so that the two movable screw rods 572 rotate respectively relative to the inside of the limiting shell 571, and when the movable screw rod 572 rotates, a synchronous driving force is provided to the bottom plate 56, so that the bottom plate 56 drives the multiple support shafts 55 thereon to move along the inside of the cleaning pool 4, and when the bottom plate 56 moves, one side of the silicone cleaning brush on the support shaft 55 contacts with the conveyor belt section 1, so that the conveyor belt section 1 is fully cleaned, and while moving, the silicone cleaning brush synchronously contacts with the removal rod 52 on its outside, and rotates while in contact, so as to achieve the effect of cleaning the solder on the outside of the air vent 13 and the outside of the removal rod 52, and further ensure the effect of fully cleaning the conveyor belt section 1 located inside the cleaning pool 4.
