Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, specifically a black busbar tinning device. Background Technology

[0002] A busbar tinning device is a piece of equipment used in the electronics manufacturing process. It is mainly used to coat the busbar with a layer of tin. This tin coating can improve conductivity, prevent oxidation, and provide better adhesion for subsequent soldering processes. The interconnecting strips left at the end of the battery cell string are soldered onto the busbar to draw out the current. Tinning the surface of the busbar can improve conductivity, prevent oxidation, and provide better adhesion for subsequent soldering processes.

[0003] The existing technology has the following shortcomings: In the prior art, application number 201621046324.X proposes a novel busbar tinning device, which includes a tin furnace, a first guide wheel inside the tin furnace, an air knife and a cooling air box arranged sequentially on the upper part of the tin furnace along the direction of the flat copper wire, a second guide wheel also arranged diagonally above the first guide wheel, and a number of grinding rods arranged in the direction of the flat copper wire in front of the first guide wheel, the number of grinding rods being alternately arranged on the upper and lower sides of the flat copper wire.

[0004] The above-mentioned equipment uses a grinding rod that is tangent to the upper and lower surfaces of the flat copper wire to prevent the flat copper wire from swaying in the solder furnace. Although the flat copper wire is not easy to sway, if the vibration generated during the flat copper wire conveying process causes a small deviation in the casting along with the flat copper wire, the deviation distance will gradually increase as the conveying continues, resulting in the flat copper wire being conveyed skewed. It does not have an automatic correction effect for the conveying of flat copper wire, and the performance can be further improved. At the same time, during the conveying process, the flat copper wire achieves a firm solder coating effect by contacting the grinding rod. However, if the contact between the flat copper wire and the grinding rod is too tight, it will take away the solder coating attached to the flat copper wire, affecting the firmness of the solder coating.

[0028] The sealing plate 3012 can be pushed out by the spring 3011, thereby ensuring that the threaded hole 303, which is not in contact with the bolt 3010, is sealed.

[0029] In this embodiment, the tin furnace 1 is provided with corresponding fan 7 and motor 2 bearing plates on both sides. The motor 2 and fan 7 are fixedly installed on both sides of the tin furnace 1, and there are three sets in total.

[0030] Specifically, motor 2 can provide sufficient power for the rotation of conveyor roller 3.

[0031] In this embodiment, the conveying roller 3 is rotatably installed inside the tin furnace 1. The inside of the conveying roller 3 is hollow. The first connecting end 301 and the second connecting end 302 are respectively fixedly installed at both ends of the conveying roller 3. The second connecting end 302 communicates with the inside of the conveying roller 3. The outer end of the first connecting end 301 extends out of the tin furnace 1 and is connected to the output end of the motor 2. The outer ring of the bearing 307 is fixedly installed inside the second connecting end 302. The output end of the fan 7 extends into the tin furnace 1 and is fixedly connected in the inner ring of the bearing 307.

[0032] Specifically, the normal rotation of the conveyor roller 3 can be ensured when air is introduced into the conveyor roller 3 through the bearing 307.

[0033] In this embodiment, there are several sets of threaded holes 303 that are adapted to bolts 3010, springs 3011 are fixedly installed at the bottom of threaded holes 303, and sealing plates 3012 are fixedly installed at the top of springs 3011.

[0034] Specifically, the threaded hole 303 can be used in conjunction with the bolt 3010 to fix the position of the limiting component 304.

[0035] In this embodiment, there are several sets of exhaust vents 305, the cover plate 306 is adapted to the exhaust vent 305, the cover plate 306 is hinged to the edge of the exhaust vent 305, and the ball bearings 308 are rotatably installed on the outer edge of the limiting component 304 and there are several sets of them.

[0036] Specifically, the ball bearing 308 prevents the flat copper wire 4 from crossing the limiting component 304 when it deviates.

[0037] In this embodiment, the fixing rod 309 is fixedly installed on one side of the limiting component 304, and the bolt 3010 passes through the fixing rod 309 and forms a threaded connection;

[0038] Specifically, the fixing rod 309 provides the conditions for the limiting component 304 to be stably installed on the conveyor roller 3.

[0039] In this embodiment, there are two sets of fixed frames 5 arranged symmetrically to each other. The air knife assembly 6 is fixedly installed on one side of the upper end of the fixed frame 5. The two sets of limiting components 304 have the same structure.

[0040] The mounting bracket 5 facilitates the installation of the air knife assembly 6, which can remove excess molten tin from the outside of the tin-plated flat copper wire 4 that is being conveyed out of the tin furnace 1.

[0041] The working principle and usage process of this utility model are as follows: In actual use, the equipment is placed in a suitable position and connected to an external power source to power the fan 7 and motor 2. The distance between the two sets of limiting components 304 is adjusted according to the width of the flat copper wire 4. During the adjustment process, after the limiting component 304 is in the appropriate position, the bolt 3010 is tightened into the threaded hole 303. The sealing plate 3012 in the threaded hole 303 will be pressed into the threaded hole 303 by the tightening force of the bolt 3010. At the same time, the spring 3011 retracts, which can provide installation space for the bolt 3010. In the threaded hole 303 that does not correspond to the bolt 3010, the spring 3011 pushes up the sealing plate 3012 to close the threaded hole 303, so as to avoid affecting the threaded hole 303 during operation. Then, the corresponding flat copper wire 4 is wound around the three sets of conveying rollers 3. When the flat copper wire 4 shifts, the flat copper wire 4 will be tightened into the threaded hole 303. The copper wire 4 is affected by the limiting component 304, and at the same time, the ball bearing 308 contacts the offset flat copper wire 4. The rolling effect of the ball bearing 308 prevents the flat copper wire 4 from crossing the limiting component 304, so that the flat copper wire 4 is adjusted to its original position, achieving the correction effect and improving the use effect. Under the action of the limiting component 304, the tin furnace 1 heats and produces molten tin. Under the action of the motor 2 driving the conveyor roller 3, the flat copper wire 4 is rotated and transported to contact the molten tin for tin plating. The air knife component 6 removes the excess molten tin from the outside of the tin-plated flat copper wire 4 after it is conveyed out of the tin furnace 1. During the tin plating process, the fan 7 generates air force and delivers it to the inside of the conveyor roller 3 through the second connection end 302. Under the action of the air pressure inside the conveyor roller 3, the cover plate 306 is opened, and air is sprayed out from the exhaust port 305, which promotes the flow of molten tin to the flat copper wire 4, improves the contact effect between the molten tin and the flat copper wire 4, and ensures the firmness of the solder coating on the flat copper wire 4.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
