Description

Triangle welding strip calendering forming device

Technical Field

The utility model relates to a triangle solder strip calendering molding device for the production of photovoltaic solder strip.

The solder strip is used in the photovoltaic cell, and the solder strip is a tin-coated copper strip. One type of solder strip is a fillet solder strip. The existing triangular welding strip production usually adopts a special-shaped wire drawing die and a profiling roller. The prior art has the advantages and disadvantages that:

one-shaped and special-shaped wire drawing die

The process is as follows: fixing the profiling wire-drawing dies on equipment according to a gradual change principle in a set sequence, ensuring the concentricity, reducing the outer diameter of one end of the blank of the welding wire, sequentially penetrating through all the wire-drawing dies, and fixing the blank of the welding wire on a take-up pulley. And (4) drawing the welding wire to form a required shape through wire drawing and molding by virtue of synchronous motion of the traction wheel and the take-up pulley.

The advantages are that: the structure is simple, and the forming is stable;

the disadvantages are as follows: the die loss is large, the welding wire loss is high, and the line speed is low and the productivity is low.

Profiling roller

The process is as follows: the traditional triangular profiling rolling strip is generally divided into an upper set of rollers and a lower set of rollers, wherein one set of rollers is V-shaped, and the other set of rollers is a plane pressing wheel. And shaping the welding strip blank into a required shape in a multi-set roller gradual shaping mode.

The advantages are that: compared with a wire drawing die, the wire drawing die has the advantages that the damage of a welding strip to the die is small in the shaping process, the linear speed is high, and the productivity is high.

The disadvantages are as follows: the profiling roller is designed as a power wheel and needs to simultaneously play roles of traction and calendering, and has poor structural strength and large die loss. The mould structure is complicated relatively, promotes the processing degree of difficulty. And the V-shaped die structure has large loss on the welding wire, and is easy to accumulate slag, thereby influencing the surface finish of the welding strip. The slag is accumulated on the surface of the welding strip to reduce the reprocessing phase of the welding strip.

The present invention is directed to improvements based on this background.

The triangle welding strip rolling and forming device shown in figure 1 is used for rolling the photovoltaic triangle welding strip. The fillet forming device comprises a bottom plate 14, and a first side plate 11 and a second side plate 12 which are arranged on two sides of the bottom plate 14. The first side plate 11 and the second side plate 12 are spaced apart by a certain distance, and a connecting rod 13 is arranged between the first side plate 11 and the second side plate 12. The connecting rod 13 serves to connect the first side plate 11 and the second side plate 12, and to space the first side plate 11 and the second side plate 12 at a distance. A nip roller is provided between the first side plate 11 and the second side plate 12.

As shown in fig. 3, the three rolls are: two plane rollers 1 and a bottom roller 2. The surface roll 1 and the back surface roll 2 are rotatably provided in the mounting frame 7, respectively. The mounting frame 7 is slidably disposed in the chute 4, and the chute 4 is opened in the first side plate 11 (and the second side plate 12). The plane roller 1 or the bottom roller 2 can be moved by sliding the mounting frame 7.

Referring to fig. 2 and 3, the sliding groove 4 is provided with two side edges with anti-slip plates 8, and the mounting frame 7 is provided with anti-slip grooves 9. The anti-slip plate 8 is embedded in the anti-slip groove 9. The arrangement of the retaining plate 8 and the retaining groove 9 is such that the mounting frame 7 cannot be released.

A spring 10 is provided, which spring 10 pushes the mounting frame 7 back to prevent the plane roller 1 and the bottom roller 2 from colliding. An adjusting screw rod 5 is further arranged, the adjusting screw rod 5 is in threaded connection with a fixing plate 6, and the fixing plate 6 is connected with a first side plate 11 and a second side plate 12. The front end of the adjusting screw 5 is tightly propped against the mounting frame 7. When the adjusting screw 5 is rotated, the front end of the adjusting screw 5 pushes the mounting frame 7 against the reverse thrust of the spring 10, so that the positions of the plane roller 1 and the bottom roller 2 can be adjusted.

As shown in fig. 4, the roll surface of the flat roll 1 is flat. The two plane rollers 1 correspond to a plane of the fillet weld. The roll surface of the bottom roll 2 is provided with grooves 21. The groove 21 corresponds to the bottom surface of the fillet bead. The roll surface of the plane roll 1 and the roll surface of the bottom roll 2 are enclosed to form a rolling hole 3, and the shape of the rolling hole 3 is matched with that of the triangular welding strip.

In the present example, as shown in fig. 4, the movement of the welding strip is limited due to the arrangement of the groove 21, and the rolling stability of the welding strip is ensured. In this example, due to the arrangement of the two flat rolls 1, slag is not easily accumulated between the roll surfaces of the two flat rolls 1, and the flat rolls 1 are easier to manufacture than the V-rolls, compared with the prior art in which only one V-roll is provided.

In summary, in this embodiment, by providing three rolls (two flat rolls 1 and one bottom roll 2), compared with the existing two rolls (including a roll with V-shaped grooves and a flat roll), the die design is simple, the loss is low, the adjustment is convenient, the rolling line speed is fast, and the slag is not easy to accumulate. And the later maintenance cost is low.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
