Description

Technical Field

[0001] This utility model relates to the field of photovoltaic welding strip technology, specifically a photovoltaic welding strip transmission and straightening device. Background Technology

[0002] Photovoltaic solder ribbon, also known as tin-plated copper ribbon or tin-coated copper ribbon, is divided into busbars and interconnects. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity and concentrating current. Solder ribbon is an important raw material in the photovoltaic module welding process. The quality of the solder ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module.

[0003] A search revealed a Chinese patent publication number: CN214767948U, entitled "A Photovoltaic Welding Strip Straightening Device." This utility model patent addresses the technical problem that "due to poor straightness of the semi-finished welding strip and the assembly precision of the conveyor wheels in traditional tin plating machines, the straightness of the solar photovoltaic welding strip is not ideal. The welding strip is not on a straight line during welding, which can cause it to deviate from the grid lines of the solar cells or even lead to cell damage when applied to series-connected solar cells. Furthermore, it cannot straighten photovoltaic welding strips of different sizes."

[0004] Based on the above technical problems, there are still issues in the process of straightening the welding strip. Because the pressure applied to the welding strip by the adjusted rotating drum is constant, when the welding strip is pulled during the straightening conveyor, the friction causes the welding strip to drive the rotating drum to rotate for straightening. This can easily lead to a large frictional force between the welding strip and the rotating drum. In particular, the tension on the welding strip at the non-straight part may damage it and reduce the quality of welding strip straightening. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic ribbon transmission and straightening device, which has the characteristics of reducing ribbon damage and improving ribbon straightening quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic welding ribbon transmission straightening device, comprising a support column fixedly installed on the top of a base, a top plate fixedly installed on the top of the support column, a first rotating shaft rotatably installed on the inner side of the base, a sprocket fixedly installed at one end of the first rotating shaft, two auxiliary sprockets rotatably installed on the front of the base, a motor fixedly installed on the front side of the base, the output end of the motor being connected to the first rotating shaft closest to the leftmost side of the base, a chain meshing with the outer side of the sprockets, and an adjustment assembly provided below the top plate, the adjustment assembly comprising two movable blocks movably installed at the bottom of the top plate.

Two movable blocks are threadedly connected to the bidirectional screw, and the two movable blocks are symmetrically arranged on the outer side of the forward thread and the reverse thread of the bidirectional screw.

[0010] To facilitate adjustment of the support plate height, in a preferred embodiment of the photovoltaic welding strip transmission straightening device of this utility model, a connecting rod is rotatably connected between the movable block and the support plate, and a cylinder is fixedly installed on the top of the support plate, the cylinder penetrating the top of the top plate and being slidably sleeved.

[0011] To facilitate the straightening of welding strips of different thicknesses, in a preferred embodiment of the photovoltaic welding strip transmission and straightening device of this utility model, a rotating roller is fixedly installed on the outer side of the first rotating shaft, a straightening groove is formed on the outer side of the rotating roller, a fixed column is fixedly installed on the bottom of the support plate, and a straightening roller is rotatably installed on the outer side of the fixed column, with the straightening roller and the straightening groove being matched in position.

[0021] In this embodiment: by setting up a motor 8, a first rotating shaft 4, and a sprocket 5, the motor 8 can drive the sprocket 5 on the outer side of the first rotating shaft 4 to rotate, so that the sprocket 5 can drive the corresponding sprocket 5 and the first rotating shaft 4 to rotate together through the chain 7, thereby enabling the conveying and straightening operation of the welding strip.

[0022] As a technical optimization of this utility model, the chain 7 is located between two auxiliary sprockets 6, and the auxiliary sprockets 6 are meshed with the chain 7.

[0023] In this embodiment: by setting an auxiliary sprocket 6, such as Figure 1As shown, the chain 7 can be positioned by two auxiliary sprockets 6, which allows the chain 7 to better drive the sprocket 5 to rotate, thus increasing the stability of the transmission.

[0024] As a technical optimization of this utility model, the adjustment component also includes a support plate 11, and a groove 15 is provided on the lower surface of the top plate 3. The groove 15 is slidably sleeved with the movable block 16.

[0025] In this embodiment: by setting the slide groove 15, the movable block 16 can slide along the slide groove 15 when it moves. The slide groove 15 can support the tension force on the movable block 16 and ensure the normal movement of the movable block 16.

[0026] As a technical optimization of this utility model, a bidirectional screw 14 is rotatably installed at the bottom of the top plate 3. A turntable 13 is fixedly installed at one end of the bidirectional screw 14. The outer side of the bidirectional screw 14 is respectively provided with a forward thread and a reverse thread. Two movable blocks 16 are threadedly connected to the bidirectional screw 14, and the two movable blocks 16 are symmetrically arranged on the outer side of the forward thread and the reverse thread of the bidirectional screw 14.

[0027] In this embodiment: by setting up a turntable 13 and a bidirectional screw 14, the corresponding movable block 16 can be driven by the bidirectional screw 14 to move along the slide groove 15. Under the action of the positive and negative threads on the outside of the bidirectional screw 14, the movable block 16 can move relative to each other.

[0028] As a technical optimization of this utility model, a connecting rod 17 is rotatably connected between the movable block 16 and the support plate 11. A cylinder 12 is fixedly installed on the top of the support plate 11, and the cylinder 12 passes through the top of the top plate 3 and is slidably sleeved. A rotating roller 9 is fixedly installed on the outer side of the first rotating shaft 4. A straightening groove 10 is opened on the outer side of the rotating roller 9. A fixed column 18 is fixedly installed on the bottom of the support plate 11. A straightening roller 19 is rotatably installed on the outer side of the fixed column 18. The straightening roller 19 and the straightening groove 10 are matched in position.

[0029] In this embodiment: by setting a connecting rod 17, when the movable blocks 16 move closer to each other, the movable blocks 16 drive the connecting rod 17 to move, and the connecting rod 17 drives the support plate 11 to move upward. When the movable blocks 16 move further apart, the movable blocks 16 drive the connecting rod 17 to move, and the connecting rod 17 drives the support plate 11 to move downward. This allows for adjustment and control of the height of the support plate 11, facilitating the docking of the straightening roller 19 at the bottom of the support plate 11 with the straightening groove 10 to perform rolling pressure straightening operations on the welding strip. By opening four straightening grooves 10 on the outside of the roller 9, four straightening operations can be performed simultaneously on the welding strip at one time, which improves efficiency compared to single conveying and straightening.

[0030] Working principle: First, the solder strip is placed as follows... Figure 4 The welding strip is passed through the straightening groove 10 located below the support plate 11. Then, the rotating turntable 13 drives the bidirectional screw 14 to rotate. The bidirectional screw 14 drives two movable blocks 16 to move closer to each other along the slide groove 15. The movable blocks 16 drive the connecting rod 17 to push the support plate 11 downward, so that the cylinder 12 at the top of the support plate 11 moves vertically along the top plate 3. At this time, the straightening roller 19 at the bottom of the support plate 11 connects with the straightening groove 10. The straightening roller 19 contacts and presses the welding strip inside the straightening groove 10. Then, the starting motor 8 drives the sprocket 5 on the outer side of the corresponding first rotating shaft 4 to rotate. The sprocket 5 can drive the corresponding sprocket 5 and the first rotating shaft 4 to rotate together through the chain 7. The first rotating shaft 4 drives the corresponding outer roller 9 to rotate, so that the welding strip can be conveyed and straightened by the rolling of the roller 9, thereby improving the straightening quality of the welding strip.
