[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Figure 1 and Figure 2 The side bending straightening device for an ultra-thin busbar slow plating machine shown in the figure comprises a pay-off wheel 1, a flux pool 2, a tinning furnace 3, a cooling channel 4, a powered pressure roller 5, a take-up wheel 6 and at least two straightening wheel assemblies 7. The above components are all mounted on a frame, and the frame is omitted in the figure. The pay-off wheel 1 is mounted at the front end of the flux pool 2, the tinning furnace 3 is mounted at the rear end of the flux pool 2, the cooling channel 4 is mounted at the rear end of the tinning furnace 3, a powered pressure roller 5 is mounted at the upper end of the cooling channel 4, and the straightening wheel assembly 7 is mounted at the front end of the powered pressure roller 5. The two straightening wheel assemblies are staggered and installed at intervals front and back, and a take-up wheel is mounted at the front end or the side front end of the straightening wheel assembly 7, wherein:

[0023] Each straightening wheel assembly includes a mounting shaft 71, on which is mounted at least one straightening wheel 72, of which there are three in the figure. An annular groove 73 is provided in the middle of the outer ring of each straightening wheel 72, and a positioning slider 74 is connected to the side of the straightening wheel 72. The positioning slider 74 has a threaded hole, into which a positioning screw 75 is screwed. The position of the straightening wheel 72 on the mounting shaft 71 can be adjusted by loosening or tightening the positioning screw 75. Each straightening wheel 72 can be adjusted without interfering with each other, and the number of straightening wheels 72 can be increased or decreased.

[0024] In order to ensure a smooth transition, a first guide roller 8 is installed between the pay-off wheel 1 and the flux pool 2, a second guide roller 9 is installed between the flux pool 2 and the tinning furnace 3, and a third guide roller 9 is installed between the tinning furnace 3 and the cooling channel 4.

[0025] The cooling channel is preferably a cooling air duct, which consists of two groups of fans with a low front and a high back. The front end is in the direction of the pay-off wheel 1, and the front fan group 11 and the rear fan group 12 are installed at intervals, and the wire passes through the interval. The wire usually refers to a copper strip substrate. The front fan group 11 includes at least one first fan. When the number of first fans is multiple, the first fan is installed flat up and down and left and right; the rear fan group 12 includes at least two second fans, and the second fans are also installed flat up and down and left and right; after the front fan group 11 and the rear fan group 12 are installed, the lowest first fan and the lowest second fan are in the same horizontal plane, and the uppermost second fan is higher than the uppermost first fan; the first fan and the second fan are both existing cooling fans.

[0026] There are two options for cooling air ducts. One is a counter-blowing cooling air duct, that is, the front fan group 11 and the rear fan group 12 blow air to each other to cool the tinned wire. The other cooling air duct is a direct-blowing cooling air duct, that is, the front fan group and the rear fan group both blow air to the rear end. In this way, a gas and dust filtering mechanism can be installed at the rear end of the rear fan group to improve the air quality of the working environment.

[0027] Regardless of the type of air duct, the rear end fan group 12 is higher than the front end fan group 11 and can effectively accumulate heat in a smaller air duct.

[0028] Actual processing time

[0029] The wire is released from the pay-off wheel 1, passes through the flux pool 2 and is tinned in the tinning furnace 3. The tinned wire is cooled through the cooling channel 4 and enters the powered pressure roller 5 for flattening. The flattened wire is then straightened by two straightening wheel assemblies 7 and then collected by the take-up wheel 6, completing the production of the ultra-thin busbar.

[0030] The straightening principle of the two straightening wheel assemblies 7 is that by adjusting the relative positions of the straightening wheel grooves 73 on the two straightening wheel assemblies 7 respectively, a lateral force can be applied to the ultra-thin busbar to correct the lateral bending of the welding strip.

[0031] The powered pressing roller 5 mainly provides the power for the wire to move forward and a part of the flattening, and does not cause a large deformation to the wire.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
