[0023] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 8 The embodiments are described in detail below.

[0024] This embodiment provides a straightening and grinding integrated machine for processing copper busbar radiators, as shown in the attached figure. Figure 1-8As shown, the system includes a base 1 and a placement platform 2 fixedly connected to the upper surface of the base 1. The base 1 has a first pressure roller mechanism inside, comprising a first pressure roller 8, a first belt 9, and a first motor 10. The base 1 has a rotating groove for preventing the first pressure roller 8 from rotating. Several first pressure rollers 8 are horizontally and equidistantly rotatably connected within the rotating groove inside the base 1. The tops of the several first pressure rollers 8 are slightly higher than the upper surface of the base 1. Both ends of the several first pressure rollers 8 are fixedly connected to spur gear shafts 11, and the external transmission connections of the several spur gear shafts 11 on the same side are connected to a first... A belt 9 is used to connect the output end of the first motor 10 to the spur gear shaft 11 on one side of the first pressure roller 8 near the placement platform 2 via a spline. Protective covers 12 are fixedly connected to both sides of the base 1, and the two protective covers 12 are respectively sleeved on the outside of the spur gear shafts 11 on both sides of several first pressure rollers 8, which can protect the spur gear shafts 11. The first motor 10 is fixedly installed on the outside of the protective cover 12 on its corresponding side. When the first motor 10 runs, it drives the corresponding spur gear shaft 11 and the first pressure roller 8 to rotate counterclockwise. It can drive all the first pressure rollers 8 to rotate counterclockwise synchronously through the first belt 9 on both sides.

[0025] Side support plates 3 are fixedly connected to both sides of the upper surface of the base 1, and a second pressure roller mechanism that can move up and down is provided inside the side support plates 3. The second pressure roller mechanism includes a second pressure roller 13, a connecting frame 14, a second belt 15, and a second motor 16. The number of second pressure rollers 13 is the same as that of the first pressure rollers 8, and both ends of the second pressure rollers 13 are fixedly connected to spur gear shafts 11. The external transmission of the spur gear shafts 11 on the same side is connected to the second belt 15. Both ends of the second pressure rollers 13 are provided with connecting frames 14, and several second pressure rollers 13 are rotatably connected between two connecting frames 14. The two connecting frames 14 are vertically slidably connected inside the two side support plates 3, and the two connecting frames 14 are on opposite sides. A protective cover 12 is fixedly connected. The output end of the second motor 16 is connected to the spur gear shaft 11 on one side of the second pressure roller 13 near the placement platform 2 via a spline. The second motor 16 is fixedly installed on the outside of the protective cover 12 on the same side and is vertically corresponding to the first motor 10. When the second motor 16 runs, it drives the corresponding spur gear shaft 11 and the second pressure roller 13 to rotate clockwise. It can drive all the second pressure rollers 13 to rotate clockwise through the second belts 15 on both sides. The lower first pressure roller 8 rotates counterclockwise, and the upper second pressure roller 13 rotates clockwise, so that the copper busbar placed between the first pressure roller 8 and the second pressure roller 13 can be conveyed to one side of the adjustable edge grinding mechanism.

[0026] A first electric lifting rod 4, which can drive the second pressure roller mechanism to move up and down, is fixedly installed on the upper surface of the side support plate 3. The movable rod of the first electric lifting rod 4 passes through the top of the side support plate 3 and its bottom end is fixedly connected to the upper surface of the connecting frame 14. There are four first electric lifting rods 4, and the four first electric lifting rods 4 are evenly divided into two groups. The two groups of first electric lifting rods 4 are fixedly installed on the upper surfaces of the two side support plates 3 respectively. The four first electric lifting rods 4 move synchronously, which can drive the second pressure roller mechanism below to move up and down as a whole, thereby facilitating the adjustment of the distance between the first pressure roller 8 and the second pressure roller 13. It is suitable for straightening copper busbars of different thicknesses.

[0027] The distance between the second pressure roller 13 and the first pressure roller 8 is adjusted to match the thickness of the copper busbar that needs to be straightened. The copper busbar is placed between the two. Under the action of rotation, the first pressure roller 8 and the second pressure roller 13 can drive the copper busbar to move inward. The first pressure roller 8 and the second pressure roller 13 can press the upper and lower surfaces of the copper busbar together, thereby flattening the uneven parts of the copper busbar surface. The multiple sets of first pressure rollers 8 and second pressure rollers 13 can straighten the copper busbar multiple times, so that the part of the copper busbar entering the first pressure roller mechanism and the second pressure roller mechanism can remain straight.

[0028] The platform 2 is internally equipped with a bottom polishing mechanism for polishing the lower surface of the copper busbar. The bottom polishing mechanism includes a base plate 17, a first pulley 18, a first rotating belt 19, a first polishing head 20, and a third motor 21. The base plate 17 is fixedly connected to the lower surface of the base 1. There are two first pulleys 18, both of which are rotatably connected to both sides of the surface of the base plate 17 via bearings. The first rotating belt 19 is driven by the external parts of the two first pulleys 18. One of the first pulleys 18 is connected to the output shaft of the third motor 21 via a spline. The three motors 21 are fixedly installed on the lower surface of the base plate 17. There are several first grinding heads 20, and these first grinding heads 20 are equidistantly fixedly connected to the outside of the first rotating belt 19 and pass through the base 1 and the placement platform 2. When the third motor 21 is running, it can drive the first pulley 18 connected to it to rotate, and drive the first rotating belt 19 to rotate, so that multiple first grinding heads 20 can rotate cyclically with the first rotating belt 19. When the straightened copper busbar moves to the top of the bottom grinding mechanism, the multiple first grinding heads 20 can fully grind the lower surface of the copper busbar.

[0029] A support frame 5 is fixedly connected to the upper surface of the base 1 at the corresponding part of the bottom polishing mechanism, and a second electric lifting rod 6 is fixedly installed on the upper surface of the support frame 5. The movable end of the second electric lifting rod 6 is provided with a top polishing mechanism that can be vertically corresponding to the bottom polishing mechanism. There are two second electric lifting rods 6, and the two second electric lifting rods 6 are symmetrically arranged with the vertical center line of the support frame 5 as the axis of symmetry. The two second electric lifting rods 6 move synchronously and can drive the top polishing mechanism to rise and fall, so as to facilitate the adjustment of the distance between the top polishing mechanism and the bottom polishing mechanism according to the thickness of the copper busbar.

[0030] The top polishing mechanism includes a top movable plate 22, a second pulley 23, a second rotating belt 24, a second polishing head 25, and a fourth motor 26. The top movable plate 22 is fixedly connected to the bottom end of the movable rod of the second electric lifting rod 6. There are two second pulleys 23, and both second pulleys 23 are rotatably connected to both sides of the top movable plate 22 through bearings. The second rotating belt 24 is driven to the outside of the two second pulleys 23. One of the second pulleys 23 is connected to the output end of the fourth motor 26 through a spline, and the fourth motor 26 is fixedly installed on the upper surface of the top movable plate 22. There are several second polishing heads 25, and several second polishing heads 25 are equidistantly fixedly installed on the outside of the second rotating belt 24. When the fourth motor 26 runs, it can drive the corresponding second pulley 23 to rotate, and drive the second rotating belt 24 to rotate, so that the multiple second polishing heads 25 rotate accordingly, and can fully polish the upper surface of the copper busbar.

[0031] A fixed frame 7 is fixedly connected to the side of the upper surface of the base 1 away from the first pressure roller mechanism. The fixed frame 7 is equipped with an adjustable edge grinding mechanism for grinding the side of the copper busbar. The adjustable edge grinding mechanism includes a fifth motor 27, a rack 28, a moving plate 29, a drive motor 30, and a grinding wheel 31. A gearbox is fixedly connected to the middle of the upper surface of the fixed frame 7, and the fifth motor 27 is fixedly installed on the upper surface of the gearbox. The output end of the fifth motor 27 is connected to a spur gear through a spline, and the spur gear passes through the inside of the gearbox. Both sides of the spur gear are meshed with racks 28, and the two racks 28 pass through the two sides of the gearbox respectively. The ends of the two racks 28 that are far apart from each other are fixedly connected to the moving plate 29, and the upper surfaces of the two moving plates 29 are fixedly installed with drive motors 30. The output ends of the two drive motors 30 are connected to the moving plate 29. A splined connection is provided with two grinding wheels 31, which are inserted below the fixed frame 7. Both grinding wheels 31 can move laterally on the fixed frame 7. The bottom end of the grinding wheel 31 is inserted into the upper surface of the placement platform 2 and can slide laterally on the upper surface. The concave part of the grinding wheel 31 corresponds to the upper surface of the placement platform 2, so that the edge of the copper busbar is pressed against the concave part of the grinding wheel 31. The fifth motor 27 can drive the racks 28 on both sides to move relative to each other through the spur gear, so as to facilitate the adjustment of the distance between the two grinding wheels 31. The grinding wheels 31 on both sides can be adjusted to a suitable distance according to the width of the straightened copper busbar, so that the grinding wheels 31 on both sides are pressed against the two sides of the copper busbar respectively. The drive motor 30 can drive the grinding wheels 31 on both sides to rotate, thereby grinding the two sides of the copper busbar and removing the burrs on the copper busbar more thoroughly.

[0032] In summary, the operating steps of this integrated straightening and grinding machine for processing copper busbar radiators are as follows:

[0033] 1. First, adjust the distance between the second pressure roller 13 and the first pressure roller 8 to be consistent with the thickness of the copper busbar that needs to be straightened. Place the copper busbar between the two. The first pressure roller 8 and the second pressure roller 13 can press the upper and lower surfaces of the copper busbar together, thereby flattening the uneven parts of the copper busbar surface. The multiple sets of first pressure rollers 8 and second pressure rollers 13 can straighten the copper busbar multiple times, so that the part of the copper busbar entering the first pressure roller mechanism and the second pressure roller mechanism can remain straight.

[0034] 2. Under the pushing action of the first pressure roller mechanism and the second pressure roller mechanism, the straightened copper busbar will move between the bottom grinding mechanism and the top grinding mechanism. The height of the top grinding mechanism is adjusted by the second electric lifting rod 6 so that it can fit against the upper surface of the copper busbar. Then the third motor 21 and the fourth motor 26 are run so that the first grinding head 20 and the second grinding head 25 can fully grind the upper and lower surfaces of the copper busbar.

[0035] 3. Based on the width of the straightened copper busbar, the fifth motor 27 adjusts the grinding wheels 31 on both sides to a suitable distance, so that the grinding wheels 31 on both sides abut against the two sides of the copper busbar. The drive motor 30 drives the grinding wheels 31 on both sides to rotate, thereby grinding the two sides of the copper busbar and removing the burrs on the copper busbar more thoroughly.

[0036] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
