Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, and in particular to a rapid cooling device for photovoltaic busbars. Background Technology

[0002] Busbars typically consist of an inner copper strip and a tin layer surrounding it. In the current manufacturing process, especially after the molten tin is coated onto the copper strip, the molten tin adhering to the copper strip needs to be cooled to solidify and form a tin layer. The existing cooling method is not efficient enough. In addition, because the molten tin contains tin dross particles, these dross particles adhere to the surface of the copper strip, affecting the surface smoothness of the busbar and even reducing its conductivity. Improvements are urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a rapid cooling device for photovoltaic busbars, which can blow off tin dross from the molten tin adhering to the copper strip, improve the surface smoothness of the busbar, and achieve rapid cooling of the busbar.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rapid cooling device for a photovoltaic busbar, comprising a tin-coating mechanism and a cooling mechanism. The tin-coating mechanism is used to wrap a tin layer around a copper strip to form a busbar. The cooling mechanism includes a purging module and a cooling tower. The tin-coating mechanism includes a tin liquid frame and a guide wheel located below the cooling tower and within the tin liquid frame. The purging module includes several purging nozzles. The cooling tower is provided with a traction wheel and a vertical conveying structure. The cooling tower is vertically provided with a cooling channel corresponding to the vertical conveying structure. A wind power generation module connected to the cooling channel is provided inside the cooling tower. The traction wheel and the vertical conveying structure cooperate to drive the busbar to be transported towards the top of the cooling tower after being reversed by the guide wheel. During the lifting process, the busbar is sequentially purged and cooled by the purging nozzles and the cooling channel.

[0005] By adopting the above technical solution, the traction wheel generates a traction force on the downstream confluence belt of the cooling tower, and in conjunction with the vertical conveying structure, pulls the copper strip coated with molten tin upstream of the cooling tower. After being redirected by the guide wheel, the copper strip adheres to a layer of molten tin within the molten tin frame. Through the blowing nozzle, the tin dross attached to the surface of the copper strip is blown off into the molten tin frame, making the molten tin on the surface of the copper strip more uniform. Simultaneously, it cools the molten tin, causing it to solidify on the surface of the copper strip and form the confluence belt. However, at this point… The surface temperature of the busbar remains high. Then, the vertical conveying structure drives the busbar to be vertically conveyed from the bottom to the top of the cooling tower in the air-cooling channel. The air-generating module generates cold air and blows it into the air-cooling channel to cool the busbar vertically conveyed in the air-cooling channel. This achieves the purpose of rapid cooling of the busbar. It can blow off the tin dross in the molten tin attached to the copper strip, improve the surface flatness of the busbar, and achieve rapid cooling of the busbar.

[0007] By adopting the above technical solution, the wind power generation module delivers cold air to the air blowing pipe through the air inlet, and the air blowing pipe then blows the cold air into the air-cooling channel through the air blowing port to cool the manifold in the air-cooling channel.

[0008] A further feature of this invention is that the blower pipe is fixedly connected to a purge cover at the blower opening position, and the purge cover is provided with a cooling nozzle tilted upwards on one side facing the air-cooling channel. The cooling nozzle communicates with the blower opening through the inner cavity of the purge cover.

[0009] By adopting the above technical solution, the cold air blown out from the air outlet of the air blower passes through the blower housing and is then blown out from the air-cooling nozzle. The inclined air-cooling nozzle can increase the blowing speed and blowing area of ​​the cold air on the surface of the confluence zone, thereby improving the cooling efficiency of the surface of the confluence zone.

[0010] A further feature of this invention is that the wind power generation module includes a chassis fixedly connected to the side of the cooling tower and a fan installed inside the chassis. The outer wall of the chassis has several air intake holes, and the end of the chassis facing the cooling tower has an air outlet. The air outlet is connected to the air intake port through a flexible hose.

[0011] By adopting the above technical solution, the fan draws in cold air from the air intake hole on the outer wall of the casing, and then blows the cold air from the air outlet side through the hose to the air inlet of the blower pipe, thereby realizing the formation and delivery of cold air.

[0012] A further feature of this invention is that each group of air-cooled pipe assemblies is equipped with several air guide sleeve assemblies, each air guide sleeve assembly having an airflow channel, the air inlet end of the airflow channel being connected to the wind power generation module, and the air outlet end of the airflow channel forming two branches that are respectively connected to the air inlets of two adjacent air blowing pipes.

[0013] By adopting the above technical solution, the addition of the air guide sleeve assembly can reduce the number of hose connections between the air inlet of the air blower and the air outlet of the wind power generation module, and improve the convenience of hose connection.

[0014] A further feature of this invention is that two purge nozzles are provided, and the two purge nozzles are respectively disposed on both sides of the flow band lifting direction.

[0015] By adopting the above technical solution, the two opposing blow nozzles can quickly blow away the molten tin on both sides of the copper strip pulled out from the molten tin frame, so that the tin dross in the molten tin can be blown off quickly, and at the same time, the molten tin can be quickly cooled and solidified on the side wall of the copper strip.

[0016] A further feature of this invention is that the two blowing nozzles are mounted on corresponding adjusting seats, the two adjusting seats are slidably mounted on the mounting plate in the horizontal direction via a guide rail structure, and the mounting plate and the corresponding mounting plate are fastened together by locking bolts.

[0017] By adopting the above technical solution, the large distance between the two adjustment seats can be adjusted using the guide rail structure, and the two adjustment seats can be locked to the mounting plate by locking bolts, thereby realizing the adjustment of the distance between the two blowing nozzles.

[0018] A further feature of this invention is that it also includes a machine tool, the machine tool being provided with a lifting drive module, the output end of the lifting drive module being connected to a lifting plate assembly, the lifting plate assembly being fixedly provided with a lifting cylinder, and the output end of the lifting cylinder being connected to the mounting plate.

[0019] By adopting the above technical solution, the lifting drive module can drive the lifting plate assembly to move up and down relative to the machine tool. At the same time, the lifting cylinder can be used to achieve fine lifting and adjustment of the mounting plate, thereby adjusting the height difference between the blow nozzle and the solder frame to find the most suitable time for blowing.

[0020] A further feature of this invention is that the blowing direction of the blowing nozzle is perpendicular to or forms an angle with the confluence zone.

[0021] By adopting the above technical solution, the air velocity and area of ​​the blower nozzle when blowing the busbar can be increased, and the slag removal performance and cooling and solidification efficiency of the blower nozzle on the side wall of the copper strip can be improved.

[0022] A further feature of this invention is that the vertical conveying structure includes a driving structure, a driving wheel, and a driven wheel. The driving wheel is rotatably mounted at the bottom of the cooling tower, and the driven wheel is rotatably mounted at the top of the cooling tower. A transmission belt is connected between the driving wheel and the transmission wheel. Both the driving wheel and the driven wheel are coaxially fixed with a guide wheel for the transport bus belt.

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] A rapid cooling device for photovoltaic busbars, such as Figure 1-8As shown, the system includes a tin-coating mechanism 1 and a cooling mechanism. A flux coating module 6 is connected upstream of the tin-coating mechanism 1. The flux coating module 6 is used to pre-coat a layer of flux onto the copper strip. The tin-coating mechanism 1 is used to wrap a tin layer around the copper strip and form a confluence belt. The cooling mechanism includes a purging module 3 and a cooling tower 4. The tin-coating mechanism 1 includes a tin liquid frame 11 and a guide wheel 2 located below the cooling tower 4 and inside the tin liquid frame 11. A heating device is provided inside the tin liquid frame 11, including several heating tubes 111 disposed within the tin liquid frame 11. The purging module 3 includes several purging nozzles 31. The cooling tower 4 is equipped with a traction wheel 40 and a vertical conveying structure 41. A vertically arranged air-cooling channel 42 is provided in the cooling tower 4 corresponding to the vertical conveying structure 41. A wind-generating module 43 connected to the air-cooling channel 42 is provided inside the cooling tower 4. The traction wheel 40 and the vertical conveying structure 41 cooperate to drive the confluence belt to be transported towards the top of the cooling tower 4 after being redirected by the guide wheel 2. During the lifting process, the busbar is sequentially cooled by blowing through the blow nozzle 31 and the air-cooling channel 42. The vertical conveying structure 41 includes a drive structure 411, a drive wheel 412, and a driven wheel 413. The drive wheel 412 is rotatably located at the bottom of the cooling tower 4, and the driven wheel 413 is rotatably located at the top of the cooling tower 4. A transmission belt 414 is connected between the drive wheel 412 and the drive wheel. Both the drive wheel 412 and the driven wheel 413 are coaxially fixed with guide wheels 415 for transporting the busbar. The groove of the guide wheel 415 is vertically aligned with the air-cooling channel 42 between the two blow pipes 44. The drive structure 411 drives the drive wheel 412 to rotate, and the drive wheel 412 drives the driven wheel 413 to rotate through the transmission belt 414. This achieves synchronous rotation of the guide wheels 415 located at the bottom and top of the cooling tower 4, so that the busbar can be vertically transported to the designated position in the air-cooling channel 42 on the cooling tower 4 through the guide wheels 415 at both ends.

[0037] like Figure 3-5As shown, the cooling tower 4 is vertically equipped with several sets of air-cooled pipe assemblies. Each set of air-cooled pipe assemblies includes two parallel air-blowing pipes 44. The air-blowing pipes 44 have an air inlet 441 and an air outlet 442. The air inlet 441 is connected to the wind power generation module 43. The air outlets 442 of the two air-blowing pipes 44 in each set of air-cooled pipe assemblies are arranged facing inwards, forming an air-cooling channel 42 between the two air-blowing pipes 44 in each set of air-cooled pipe assemblies. The wind power generation module 43 delivers cold air to the air-blowing pipes 44 through the air inlet 441. The air-blowing pipes 44 then blow the cold air into the air-cooling channel 42 through the air outlets 442. The manifold within 42 is cooled by airflow. Simultaneously, the air outlets 442 of the two air blowers 44 are positioned facing inwards to simultaneously purge both sides of the manifold, improving the overall cooling efficiency. A purge cover 443 is fixedly connected to the air outlet 442 of the air blower 44. An air-cooling nozzle 443 is inclined upwards on the side of the purge cover 443 facing the air-cooling channel 42. The air-cooling nozzle 4431 communicates with the air outlet 442 through the inner cavity of the purge cover 443. The cold air blown from the air outlet 442 of the air blower 44 passes through the purge cover 443 and exits from the air-cooling nozzle 4431. The air-cooling nozzle 4431 can increase the blowing speed and area of ​​the cold air on the surface of the confluence belt, thereby improving the cooling efficiency of the confluence belt surface. The wind power generation module 43 includes a casing 431 fixedly connected to the side of the cooling tower 4 and a fan 432 installed in the casing 431. The outer wall of the casing 431 has several air intake holes 4311. The end of the casing 431 facing the cooling tower 4 has an air outlet 4312. The air outlet 4312 is connected to the air intake port 441 through a hose. When the fan 432 runs, it draws in cold air from the air intake holes 4311 on the outer wall of the casing 431, and then draws the cold air out from the air outlet 4312. One side blows air through a hose to the air inlet 441 of the air blower 44 to form and deliver cold air; each air-cooled pipe assembly is equipped with several air guide sleeve assemblies 45, and the air guide sleeve assembly 45 has an airflow channel 451. The air inlet end of the airflow channel 451 is connected to the wind power generation module 43, and the air outlet end of the airflow channel 451 forms two branches and is connected to the air inlet 441 of the two adjacent air blowers 44 respectively. The addition of the air guide sleeve assembly 45 can reduce the number of hose connections between the air inlet 441 of the air blower 44 and the air outlet 4312 of the wind power generation module 43, and improve the convenience of hose connection.

[0038] like Figure 6-8As shown, there are two blow nozzles 31, which are positioned opposite each other on both sides of the busbar lifting direction. These two opposing blow nozzles 31 can quickly blow away the molten solder on both sides of the copper strip pulled from the molten solder frame 11, allowing the molten solder dross to be quickly blown off and facilitating rapid cooling and solidification of the molten solder on the sidewalls of the copper strip. The two blow nozzles 31 are mounted on corresponding adjusting seats 54. The two adjusting seats 54 are slidably mounted on the mounting plate 53 in the horizontal direction via a guide rail structure 531. The mounting plate 53 and the corresponding mounting plate 54 are fastened together by locking bolts 55. The guide rail structure 531 can be used to adjust the maximum distance between the two adjusting seats 54, and the locking bolts 55 can be used to lock the two adjusting seats 54 onto the mounting plate 53, thereby adjusting the distance between the two blow nozzles 31. The system also includes a machine tool 5, which is used for... A through hole 50 for the busbar to pass through should be provided. A lifting drive module 51 is provided on the machine tool 5. The output end of the lifting drive module 51 is connected to a lifting plate assembly 52. ​​A guide wheel 415 is rotatably mounted on the lifting plate assembly 52. ​​A lifting cylinder 521 is fixed on the lifting plate assembly 52. ​​The output end of the lifting cylinder 521 is connected to the mounting plate 53. The lifting drive module 51 can drive the lifting plate assembly 52 to move up and down relative to the machine tool 5. At the same time, the lifting cylinder 521 is used to achieve fine lifting and adjusting of the mounting plate 53, thereby adjusting the height difference between the blow nozzle 31 and the molten solder frame 11 to find the most suitable blowing time. The blowing direction of the blow nozzle 31 is perpendicular to or forms an angle with the busbar, which can improve the wind speed and area of ​​the blow nozzle 31 when blowing the busbar, and improve the slag removal performance and cooling and solidification efficiency of the blow nozzle 31 on the molten solder on the side wall of the copper strip.

[0039] The basic working principle of this utility model is as follows: By setting up a tin coating mechanism 1 and a cooling mechanism, the tin coating mechanism 1 is used to wrap a tin layer around the copper strip and form a confluence belt. The cooling mechanism includes a purging module 3 and a cooling tower 4. The tin coating mechanism 1 includes a tin liquid frame 11 and a guide wheel 2 located below the cooling tower 4 and inside the tin liquid frame 11. The cooling tower 4 is equipped with a traction wheel 40 and a vertical conveying structure 41. The traction wheel 40 generates a traction force on the confluence belt downstream of the cooling tower 4, and together with the vertical conveying structure, pulls the copper strip wrapped with tin liquid upstream of the cooling tower 4. After the guide wheel 2 changes direction, the copper strip moves towards the cooling tower 4. A layer of tin liquid adheres to the copper strip inside the tin liquid frame 11. After being purged by the purging nozzle 31, the tin dross attached to the tin liquid adhering to the surface of the copper strip is removed. The molten tin is blown into the molten tin frame 11, making the molten tin on the surface of the copper strip more uniform. At the same time, it can also cool the molten tin, causing it to solidify on the surface of the copper strip to form a confluence belt. However, the surface temperature of the confluence belt is still relatively high at this time. Then, the vertical conveying structure 41 drives the confluence belt to be vertically conveyed from the bottom of the cooling tower 4 to the top of the cooling tower 4 in the air-cooling channel 42. The wind generating module 43 generates cold air and blows it into the air-cooling channel 42, and cools the confluence belt vertically conveyed in the air-cooling channel 42. This achieves the purpose of rapid cooling of the confluence belt. It has the effects of blowing off the tin dross in the molten tin attached to the copper strip, improving the surface flatness of the confluence belt, and achieving rapid cooling of the confluence belt.
