[0021] Refer to the attached Figure 1-8The copper wire tinning device comprises a frame 10, a tinning assembly 5 and an air cooling assembly. The tinning assembly is installed in the middle and lower part of the frame 10, and an air cooling assembly is designed above the tinning assembly 5. The air cooling assembly is installed in the upper part of the frame 10. The tinning assembly 5 comprises a furnace body 51, a lifting screw 52, ​​a worm gear assembly 53, a driving motor 54, a support plate 55, and a guide rod 56. The lifting screw 52 is fixedly installed in the middle of the lower end of the furnace body 51, a support plate 55 is installed below the furnace body 51, and a worm gear assembly 53 is installed in the middle of the support plate 55. The lower end of the lifting screw 52 is rotatably installed in the middle of the worm gear assembly 53 and the lower end of the lifting screw 52 passes through the support plate 55. The driving motor 54 is installed on one side of the support plate 55. The driving end of the driving motor 54 is connected to the worm gear assembly 53. Two guide rods 56 are respectively installed on both sides of the lower end of the furnace body 51. A guide hole is opened on the support plate 55 near the four corners, and the guide rods 56 are respectively slidably installed in the guide holes. The furnace body 51 is designed as an open rectangular trough, and a guide assembly 58 for tinning copper wire is designed above the furnace body 51. The lower end of the support plate is installed above the inside of the frame 10 of the copper wire tinning device through a vertical support. In the view given by the present invention, the furnace body is installed on a support plate, the middle of the lower end of the support plate is fixed on the screw rod, and the guide rod is installed on the lower end of the support plate. Whether to use a support plate is not the main technical problem to be solved by the present invention. As long as it does not deviate from the conceptual scope of the present invention, it is within the protection scope of the present invention.

[0022] The guide assembly 58 includes a semicircular guide block, and a guide groove for the copper wire to be wound around the semicircular surface of the semicircular guide block is designed. The semicircular side of the semicircular guide block is installed toward the furnace body 51 below, and one side of the semicircular guide block is fixedly installed on the frame 10 of the copper wire tinning device through a vertical plate. The semicircular guide block design saves materials and meets the winding requirements. The guide groove ensures that the copper wire will not fall out of the semicircular guide block of the guide assembly, which is safe and reliable.

[0023] The worm gear assembly 53 includes a worm, a worm wheel, and a fixed sleeve. The worm wheel is rotatably mounted in the middle of the coaxial fixed sleeve. The worm is rotatably mounted on one side of the fixed sleeve and the worm and the worm wheel are meshed and connected. An internal thread is designed in the middle of the worm wheel. The lifting screw 52 is rotatably mounted in the middle of the worm wheel and the upper and lower ends of the lifting screw 52 pass through the fixed sleeve respectively. This design belongs to the prior art and is briefly described in the present invention, such as patent CN202223371971.6.

[0024] When in use, the driving motor controls the rotation of the worm, and the worm drives the worm wheel to rotate, and the worm wheel interacts with the lifting screw through the threaded action. The upper part of the lifting screw is fixed to the bottom of the furnace body, and the bottom of the furnace body is fixed and guided by four guide rods. It can only be lifted up and down, but cannot rotate. In this way, the lifting screw brings the furnace body down, so that the guide component immersed in the tinning solution in the furnace body is separated. In this way, it is very convenient for the operator to bypass the copper wire 4 through the guide groove of the semicircular guide block of the guide component to complete the winding, and then control the driving motor to rotate in the opposite direction. The lifting screw brings the furnace body to reset, so that the guide component with the copper wire wound is immersed in the tinning solution again, and the tinning operation can be carried out. This process does not require operations such as cooling or discharging the tinning solution in the furnace body, which saves time and effort. The operator will not contact the tinning solution, which is safe and reliable.

[0025] An air cooling component includes an air distribution body 1 and an air distribution nozzle 2. The air distribution body 1 is designed as a rectangular body with a hollow chamber 11 inside. A U-shaped groove 3 for the copper wire 4 to pass through is opened in the middle of one side of the rectangular body. A plurality of air distribution nozzles 2 are respectively installed on the inner side walls of the U-shaped groove 3. The hollow chamber is connected to the air distribution nozzle 2. An air inlet 12 is designed on the other side of the rectangular body. The air distribution nozzle 2 is designed as a V-shaped flat blowing port 21 or a DC plate blowing port. The copper wire 4 passes through the middle position of the mouth of the blowing port 21.

[0026] The V-shaped flat air blowing port also includes a ball socket 22 and a connecting pipe 23. One end of the connecting pipe 23 is fixed on the side wall of the U-shaped groove 3. The other end of the connecting pipe 23 is designed as a hollow ball head. The inner end of the air blowing port 21 is set as the ball socket 22. The air blowing port 21 can be rotatably installed on the outer side of the hollow ball head of the connecting pipe 23 through the ball socket 22. The movable connection mode of the ball socket and the hollow ball head ensures that the air blowing port can be rotated to adjust the blowing direction to meet different cooling requirements. The connecting pipe connects the air blowing port with the hollow chamber.

[0027] The U-shaped groove 3 of the air distribution body 1 is installed toward the front side, and the copper wire 4 enters from the lower side of the U-shaped groove 3 and is led out from the top or near the top. A baffle 31 is designed at the lower end of the U-shaped groove 3, and the baffle 31 is designed with a small U-shaped opening for the copper wire 4 to pass through. The baffle design prevents the tinning solution on the copper wire from being blown off by the wind and falling on other components, which is a safety design. The air distribution body is vertically installed above the tinning mechanism 5, which is convenient for cooling the copper wire after tinning. This is the prior art, and the present invention is briefly described.

[0028] The DC plate-type air outlet includes an upper straight plate 61 and a lower straight plate 62. A plurality of air outlets are provided on the side wall of the U-shaped groove 3. The upper straight plate 61 is installed on the upper side of the air outlet, and the lower straight plate 62 is installed on the lower side of the air outlet. The upper straight plate 61 and the lower straight plate 62 are installed in parallel. This structural design has low installation cost.

[0029] The V-shaped flat air outlets or DC plate-type air outlets inside the air distribution body are designed to be any one of the following structural modes: side by side blowing, side by side blowing upward, side by side blowing horizontally, and side by side blowing upward. The cooling effects of the left and right air outlets are different due to different installation positions and blowing direction designs. The cooling effect of the present invention is best when the interval design is combined with the oblique blowing method.

[0030] Numerical simulation experiments were conducted on four air ducts with different outlet structures. The model was mainly built using UG software, and the built model was divided into unstructured grids using ICEM software. After that, the commercial CFD calculation software Fluent was imported for numerical simulation. The numerical simulation is based on pressure solution and adopts Turbulence model, using the Coupled algorithm suitable for simulating steady-state processes to solve the calculation model. In addition, the working pressure is set to normal pressure, the inlet pressure is 5atm, the outlet pressure is 1atm, the inlet and outlet temperatures are both normal temperature 300K, and the wire wall temperature is set to 503K. The data is as follows, Air distribution nozzle structure parameters Blow upward at intervals on the left and right Blow side by side and upward diagonally Left and right interval flat blowing Side by side blowing Outlet flow kg / s 10.14 9.42 14.56 12.5 Total inlet pressure atm 5 5 5 5 Total outlet pressure atm 1.42 1.34 1.52 1.27 Total pressure loss 0.716 0.732 0.696 0.746 <![CDATA[Convective heat transfer coefficient w / (m 2 ·K)]]> 4973.55 3306.45 2288.15 2906.7 Through the comparison in the above table, it can be concluded that the total pressure loss of the four structures is relatively large, and the total pressure loss of the four structures is not much different. In addition, the total pressure loss of the interval setting structure is smaller than that of the side-by-side setting structure. The convective heat transfer coefficient of the left and right interval upward oblique blowing structure is 4973.55w / (m2·K) The largest, while the convective heat transfer coefficient of the left and right interval flat blowing structure is 2288.15w / (m2·K) The smallest, the heat exchange effect of the left and right interval upward oblique blowing structure is the best.

[0031] When in use, after the copper wire is tinned by the tinning mechanism 5, the copper wire passes through the tin furnace of the tinning mechanism 5, and then enters from the small U-shaped opening of the lower end baffle of the air distribution body, and then passes between the blowing ports on the left and right sides, and then leads out from the upper or near the upper position of the wire wheel, the blowing port is rotated to adjust the blowing direction as needed, the air inlet starts to take in air, and the wind enters the hollow chamber of the air distribution body, and the hollow chamber evenly divides the air flow into each V-shaped flat blowing port or DC plate blowing port. The blowing ports on the left and right sides are designed to be blown side by side on the left and right, blow obliquely upward on the left and right sides, and blow flatly at intervals on the left and right sides. In the present invention, the copper wires in the air distribution body have the same air cooling height, and the cooling effect is best in this way of blowing obliquely upward at intervals on the left and right sides. In this way, the height of the air distribution body can be shortened, and there is no need for an excessively long cooling channel. The heat of the copper wire after tinning can be quickly reduced in a short distance and in a short time, which is convenient for the copper wire winding operation at the beginning, and there is no need to climb up for winding, which reduces the volume, reduces the cost, and greatly improves the cooling effect.
