Description

Technical Field

[0001] This application relates to the field of copper busbar processing, and particularly to a copper busbar surface cleaning tooling. Background Art

[0002] In the field of modern industrial automation, as a key power control device, frequency converters are widely used in various motor drive systems. As an important conductive component inside the frequency converter, the performance and reliability of the copper busbar directly affect the operation effect of the entire frequency converter. With the long-term operation of the frequency converter, various dirt and oxides will gradually accumulate on the surface of the copper busbar. On the one hand, in the industrial environment, dust, oil stains, and other impurities in the air will continuously settle on the surface of the copper busbar. These impurities will reduce the electrical conductivity of the copper busbar, increase the loss during the power transmission process, and thus affect the efficiency and energy-saving effect of the frequency converter.

[0003] After retrieval, a utility model patent with the patent number CN220481135U, a surface treatment device for copper busbar production, aims at the problems of slow working efficiency, low automation level, troublesome replacement of the dust removal plate, difficult dust treatment, and incomplete cleaning in the background art, and now proposes the following solutions, including a pedestal. A surface treatment chamber is installed on the outer wall of the top of the pedestal, and a surface treatment mechanism is arranged inside the surface treatment chamber. The surface treatment mechanism includes symmetrically distributed first traction rollers arranged on one inner wall of the surface treatment chamber. In the surface treatment mechanism of the present utility model, automatic treatment of the copper busbar surface is realized, with fast working efficiency and high automation level. In the dust removal and filtration mechanism, while achieving the dust removal and filtration effect, the filter cotton can be quickly replaced, and after the dust collection box is filled with dust, the dust can be removed for treatment. In the cleaning mechanism, the cleaning measures for the copper busbar are increased, and the dust is cleaned more thoroughly.

[0004] However, there are certain deficiencies in the use of this patent. For example, since the grinding rollers and traction rollers in the surface treatment mechanism are fixedly installed, only copper busbars with the same thickness can be surface polished during the working process, thus reducing the service performance. Moreover, the copper busbar will shift during the traction process of the traction rollers, thereby affecting the surface cleaning quality. Utility Model Content

[0025] An embodiment of this application discloses a copper bar surface cleaning tooling, including a workbench 1. A processing chamber 2 is arranged at the top of the workbench 1. A first cleaning mechanism is arranged inside the processing chamber 2. Symmetric openings are provided on both side walls at the two ends of the processing chamber 2. A fixed seat is arranged at the top of one of the openings. A first motor 3 is installed on the top of the fixed seat. One end of the first motor 3 is connected to one end of a lead screw 4 rotatably installed at the edge of the opening on one side wall at one end of the processing chamber 2 on the top of the workbench 1. A cleaning groove is also provided at the edge near one end of the top of the workbench 1. Two symmetric support plates 5 are arranged at the two ends of the cleaning groove. A second cleaning mechanism is installed between the two support plates 5.

[0026] Referring to Figure 1 and Figure 2 , the first cleaning mechanism includes a fixing plate 6. Two symmetric fixing blocks are arranged at the bottom of the fixing plate 6. An upper grinding roller 7 is rotatably installed between the two fixing blocks. Two movable blocks 8 are also arranged at both ends of the fixing plate 6. One end of one of the movable blocks 8 passes through the opening on one side wall at one end of the processing chamber 2 and is adaptively installed with the lead screw 4. One end of the other movable block 8 is slidably installed on a first sliding rod 9 arranged inside the opening on the other side wall at one end of the processing chamber 2. Two groups of symmetric connecting rods 10 are also arranged on both sides of the fixing plate 6. Two symmetric groups of fixing blocks are arranged at the bottom of one end of the two groups of connecting rods 10. Two identical traction rollers 11 are rotatably installed between the fixing blocks. More specifically, by driving the first motor 3 to drive the lead screw 4 to rotate, the lead screw 4 drives the fixing plate 6 to slide up and down along the openings provided on both side walls at the two ends of the processing chamber 2, thereby driving the upper grinding roller 7 arranged at the bottom to adjust the distance from the lower grinding roller 13, and at the same time driving the two traction rollers 11 to adjust the distance, so as to polish and clean the surfaces of copper bars with different thicknesses, improving the practicability.

[0027] Referring to Figure 3, at the bottom positions of the two end side walls of the processing chamber 2, two sets of symmetric cylinders 12 are provided at the top of the workbench 1. One end of the two sets of cylinders 12 passes through the through holes opened in the side walls of the processing chamber 2 and is connected with a limiting component. A groove is opened directly below the upper grinding roller 7 at the top of the workbench 1. A lower grinding roller 13 is rotatably installed inside the groove. The upper grinding roller 7 and the lower grinding roller 13 correspond to each other vertically. A chip guiding hopper is also provided at the bottom of the groove. The limiting component includes two symmetric movable frames 14. A plurality of uniformly arranged rollers 15 are rotatably installed inside the two sets of movable frames 14. Two sets of symmetric sliders 16 are provided at the bottom of the movable frame 14. The two sets of sliders 16 are slidably installed on two second sliding rods 17 arranged inside two symmetric sliding grooves opened at the top of the workbench 1. More specifically, by driving the two sets of cylinders 12 to drive the two movable frames 14 to slide towards each other along the second sliding rods 17 through the sliders 16 provided at the bottom, the rollers 15 rotatably installed inside the two movable frames 14 limit the copper bar. At the same time, the rollers 15 facilitate the traction roller 11 to traction the copper bar, thereby preventing the copper bar from shifting during the surface grinding and cleaning process and improving the quality of grinding and cleaning.

[0028] Reference Figure 4 and Figure 5 , the second cleaning mechanism includes two identical brush rollers 18. One end of one of the brush rollers 18 is rotatably installed in the shaft hole opened in the side wall of one of the support plates 5. The other end of the brush roller 18 passes through the shaft hole opened in the side wall of the other support plate 5 and is connected with the second motor 19. A transmission wheel 20 is also installed at the other end of the brush roller 18. A belt 21 is sleeved on the transmission wheel 20. The other end of the belt 21 passes through the through slot opened at the bottom of one side of the other support plate 5 and is sleeved with the transmission wheel 20 installed at one end of the other brush roller 18. The other brush roller 18 is rotatably installed in the cleaning slot opened between the two support plates 5 at the top of the workbench 1. More specifically, by driving the second motor 19, under the driving action of the two transmission wheels 20 installed at one end of the two brush rollers 18 and the belt 21, the two brush rollers 18 rotate simultaneously to clean the dust remaining after grinding the top and bottom surfaces of the copper bar, thereby improving the cleaning effect.

[0029] The implementation principle of a copper bar surface cleaning tooling in an embodiment of this application is as follows: During use, place the copper bar on the workbench 1, drive two groups of cylinders 12 to drive two movable frames 14 to slide towards each other along the second slide bar 17 through the sliders 16 arranged at the bottom, so that the rollers 15 rotatably installed inside the two movable frames 14 limit the copper bar to prevent the copper bar from shifting. At the same time, the rollers 15 facilitate the movement of the copper bar. Drive the first motor 3 to drive the lead screw 4 to rotate, so that the fixed plate 6 drives the upper abrasive roller 7 arranged at the bottom and the two traction rollers 11 to be adjusted to the top position of the copper bar. Then drive the traction rollers 11 to drive the copper bar to move between the upper abrasive roller 7 and the lower abrasive roller 13 for double-sided grinding. Then move the copper bar between the two brush rollers 18 through the traction rollers 11, and drive the second motor 19 to drive the two brush rollers 18 to rotate simultaneously to clean both sides of the copper bar, thereby improving the cleaning effect.
