Description

Black bus bar tin coating die

Technical Field

The utility model relates to the field of tin coating dies, in particular to a black bus bar tin coating die.

Background

The solder strip is also called as a tin-coated copper strip, is formed by coating a layer of soldering tin with uniform thickness on the surface of a flat strip-shaped copper strip with a certain size, has the main function of playing the role of connection and electric conduction of a battery plate and a junction box in the production of a photovoltaic module, has close relation with performance indexes, the current collection efficiency of the photovoltaic module, the fragment rate of the battery plate, the long-term reliability of the photovoltaic module and the like, and is an important part in the welding process of the photovoltaic module.

The surface of the welding strip in the prior art is clean and smooth, so that light reflection can occur, a black ink layer is coated on one surface of the welding strip, which is far away from soldering tin, for absorbing light, in the production process, the welding strip is usually placed into a tin furnace to be contacted with the soldering tin, so that two surfaces of the welding strip are both attached with tin coating layers, and then the black ink layer is coated on the tin coating layer on one surface, so that the produced welding strip is also called a black bus strip.

The production process requires that the coating thickness of two surfaces of the welding strip is kept consistent, the most ideal state is that one surface of the welding strip is coated with a tin coating, and the other surface of the welding strip is coated with a black ink layer, however, in the prior art, the tin coating is difficult to be carried out on one surface of the welding strip. During the tin coating operation, the solder strip is usually placed into a tin furnace to contact with the solder, so that both sides of the solder strip have the same thickness of the tin coating, and at the moment, the black ink layer is coated on the tin coating on one side of the solder strip, which inevitably causes the thickness of the coating on both sides of the solder strip to be inconsistent. If the tin-coated layer close to one side of the black ink layer is too thick, the tin-coated layer is easily melted at high temperature when the finished product welding strip is welded for use, and the black ink layer is easily faded.

Therefore, a new solution is needed to solve this problem.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an embodiment of the present application provides a black bus bar tin coating mold, which includes a bracket 1 and a connecting plate 2 fixed on the bracket 1. Be fixed with XZ axle micrometer fine setting slip table 3 on the connecting plate 2, the output of XZ axle micrometer fine setting slip table 3 is fixed with the die holder 4, vertically fixed with first module 5 and second module 6 on the die holder 4, be formed with between first module 5 and the second module 6 and be used for the work piece to pass through scribble tin passageway 9, be provided with on the support 1 and be arranged in supporting the location to scribbling the bracing piece 7 in the tin passageway 9 with the work piece. The XZ-axis micrometer fine-tuning sliding table 3 comprises a Z-axis micrometer fine-tuning sliding table 31 fixed on the connecting plate 2 and an X-axis micrometer fine-tuning sliding table 32 fixed on the output end of the Z-axis micrometer fine-tuning sliding table 31.

It should be noted that the supporting rod 7 is only used for supporting and positioning the workpiece, so that the workpiece does not slide with the first module 5 and the second module 6, and an external clamping device is also needed to clamp the workpiece in the actual use process. The X-axis micrometer fine-tuning sliding table 32 and the Z-axis micrometer fine-tuning sliding table 31 are both in the prior art, and are not described in detail in this embodiment.

When the tin coating die is used, one end of a workpiece is clamped on an external clamping device, the supporting rod 7 is abutted against the workpiece, and the other end of the workpiece extends into the tin coating channel 9.

Then according to the production process requirement, the X-axis micrometer fine adjustment sliding table 32 is adjusted to drive the first module 5 and the second module 6 to slide along the vertical line of the workpiece in the same direction, so that the distance between the first module 5 and the workpiece and the distance between the second module 6 and the workpiece are different. Thus, when the spacing between the workpiece and the first module 5 needs to be larger than the spacing between the workpiece and the second module 6, since the workpiece does not slide with respect to the first module 5 and the second module 6, it is only necessary to move the first module 5 and the second module 6 simultaneously in the left direction shown in fig. 1, and vice versa.

And then adjusting the fine adjustment sliding table 31 of the Z-axis micrometer to drive the first module 5 and the second module 6 to vertically lift, so that the stretching amount of the workpiece stretching into the tin coating channel 9 can be controlled.

Finally, the part of the utility model is placed in a tin furnace so that solder flows from the solder-coating channel 9, thereby enabling the two sides of the workpiece to be attached with different thickness of the solder coating.

By the mode, the two surfaces of the workpiece are coated with the tin coating layers with different thicknesses, so that when the thin surface of the tin coating layer is coated with the black ink layer with a certain thickness, the production process requirement that the thicknesses of the coatings on the two surfaces of the workpiece need to be consistent can be met.

On the basis, as shown in fig. 2, 3 and 4, the second module 6 is provided with a longitudinally through slot 61, and the tin-coated channel 9 is formed between the slot 61 and the first module 5.

When the workpiece extends into the tin-coated channel 9, the two side walls of the notch 61 can abut against the workpiece to limit the left and right positions of the workpiece.

Through the setting of fluting 61, when soldering tin flowed in scribble tin passageway 9, the both sides wall of fluting 61 is contradicted on the work piece, when realizing carrying on spacingly to the work piece, can also effectively avoid soldering tin to flow in the both sides wall of work piece for the scribble tin on work piece both sides is more even.

In addition, as shown in fig. 4, a first arc portion 51 and a second arc portion 62 are respectively disposed at one end of the first module 5 and one end of the second module 6 close to the support rod 7, and a flared portion 8 is formed between the first arc portion 51 and the second arc portion 62.

In operation, a flared part 8 with an opening larger than the tin-coated channel 9 is formed between the first arc part 51 and the second arc part 62.

Through the arrangement of the first arc part 51 and the second arc part 62, the workpiece can be stretched into the workpiece more conveniently and quickly.

On the basis, as shown in fig. 1, the connecting plate 2 is fixedly connected with the bracket 1 through bolts.

Through the setting of bolt for connecting plate 2 can be dismantled with support 1, can install connecting plate 2 and the part that sets up on connecting plate 2 to other support 1 according to the user demand like this, have the advantage of using in a flexible way.
