Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically a polishing device for copper strip surface treatment. Background Technology

[0002] Copper strip is a strip-shaped object made of copper, mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, and connectors. It is primarily used for conductive, thermally conductive, and corrosion-resistant materials. During the processing of copper strip, the surface often becomes contaminated with dust and water stains. To facilitate later packaging and use, the produced copper strip needs to be polished.

[0003] After processing, copper strips may be bent. Bending causes creases on the surface of the copper strip. When copper strips with creases are polished directly, the side with creases will be polished too much, while the side without creases will be polished less. This will cause deviations in the thickness of the copper strip, resulting in inconsistent thickness. Utility Model Content

[0033] Please see Figure 1-4 As shown, this utility model is a polishing device for copper strip surface treatment, comprising:

[0034] A base plate 100 is fixedly connected to the top of the base plate 100, and two upright plates 111 are fixedly connected to the top of the operating table 110. The surfaces of the two upright plates 111 are respectively provided with sliding grooves 112.

The driven column 380 is rotatably connected to the driven shaft 291 at the other end and slidably connected to another slide groove 112. Within 12, the second motor 310 is started, which drives the drive screw 320 to rotate. The drive screw 320 drives the L-shaped slide column 330 to slide in the slide groove 112. The L-shaped slide column 330 drives the driven shaft 291 to slide, thereby driving the driven flattening roller 290 to slide. The driven flattening roller 290 drives the driven shaft 291 at the other end to slide, thereby driving the driven column 380 to slide in another slide groove 112. The drive screw 320 drives the drive helical gear 340 to rotate, which drives the driven helical gear 370 to rotate. The driven helical gear 370 drives the slide column 240 to slide in the slide rail 350. The slide column 240 drives the fixed column 250 and the tensioning wheel 260 to slide. The distance between the drive flattening roller 220 and the driven flattening roller 290 can be adjusted according to the thickness of the copper strip to increase the applicable range.

[0040] A polishing mechanism 400 is fixedly connected in the middle of the operating table 110, and a winding mechanism 600 is fixedly connected on the other side of the top of the operating table 110. Both the polishing mechanism 400 and the winding mechanism 600 are existing structures and will not be described. After the copper strip passes through the flattening mechanism, it is polished by the polishing mechanism 400 and then wound up by the winding mechanism 600.

[0041] Working principle: Based on the thickness of the copper strip, the second motor 310 is started. The second motor 310 drives the drive screw 320 to rotate. The drive screw 320 drives the L-shaped slide column 330 to slide within the slide groove 112. The L-shaped slide column 330 drives the driven shaft 291 to slide, thereby driving the driven flattening roller 290 to slide. The driven flattening roller 290 drives the driven shaft 291 at the other end to slide, thereby driving the driven column 380 to slide within another slide groove 112. The drive screw 320 drives the drive helical gear 340 to rotate. The drive helical gear 340 drives the driven helical gear 370 to rotate. The driven helical gear 370 drives the slide column 240 to slide within the slide rail 350. The slide column 240 drives the fixed column 250 and the tensioning wheel 260 to slide, thus moving the drive flattening roller 220 and... After the spacing of the driven flattening rollers 290 is adjusted to a suitable position, the first motor 210 is started. The first motor 210 drives the drive shaft 221 at one end to rotate, thereby driving the drive flattening roller 220 to rotate. The drive flattening roller 220 drives the drive shaft 221 at the other end to rotate, thereby driving the drive wheel 230 to rotate. The drive wheel 230 drives the tension wheel 260 and the driven wheel 270 to rotate through the transmission belt 280. The driven wheel 270 drives the driven shaft 291 to rotate, thereby driving the driven flattening roller 290 to rotate. The rotation of the drive flattening rollers 220 and the driven flattening roller 290 flattens the copper strip before polishing. This not only avoids inconsistent thickness of the copper strip after polishing due to bending, thus improving the quality of the copper strip, but also makes it suitable for copper strips of different thicknesses, improving the practicality of the device.

[0042] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The collection mechanism includes a lower protective cover 510, an upper protective cover 520, a landslide pipe 530, an absorption pipe 540, a collection box 550, a filter element 560, and a dust pump 570.

[0044] The lower protective cover 510 is fixedly connected to the top center of the operating table 110, the upper protective cover 520 is rotatably connected to the side wall of the lower protective cover 510, the landslide pipe 530 is fixedly connected to the bottom surface of the operating table 110, the two ends of the absorption pipe 540 are fixedly connected to the bottom of the landslide pipe 530 and the side wall of the collection box 550 respectively, the collection box 550 is fixedly connected to the top surface of the base plate 100, the filter element 560 is fixedly connected to the inner wall of the collection box 550, and the filter element 560 is fixedly connected to the other side of the collection box 550. The upper protective cover 520 and the lower protective cover 510 are closed to cover the polishing mechanism 300 to prevent copper chips from splashing and injuring personnel. The copper chips are sucked into the landslide pipe 530 and the absorption pipe 540 by the dust pump 570 and then enter the collection box 550 and are isolated and stored in the collection box 550 by the filter element 560.

[0045] A connecting ring 551 is fixedly connected to the inner wall of the collection box 550. An L-shaped groove 552 is opened in the inner wall of the connecting ring 551. A box door 553 is rotatably connected to the front of the collection box 550. A protrusion 561 is fixedly connected to the side wall of the filter element 560. The protrusion 561 slides in the L-shaped groove 552. The box door 553 is rotated to clean copper shavings and replace the filter element 560. The filter element 560 is rotated to make the protrusion 561 slide from the long side to the short side of the L-shaped groove 552. The filter element 560 is pulled to make the protrusion 561 slide out along the short side of the L-shaped groove 552. After cleaning or replacing the filter element 560, the protrusion 561 on the filter element 560 is aligned with the short side of 512 and inserted into the long side of the L-shaped groove 552. The filter element 560 is rotated to make 562 rotate to the innermost side of the long side of the L-shaped groove 552, so that the filter element 560 is fixed in the connecting ring 551.

[0046] The lower protective cover 510 has two perforations 511 on one side wall. Another perforation 511 is opened on the other side of the lower protective cover 510. The copper strip is passed through the two perforations 511 one after the other.

[0047] Working principle: The copper strip passes through the flattening mechanism 200 and then through the perforation 511 on one side of the lower protective cover 510, where it is polished by the polishing mechanism 300. It then exits through the perforation 511 on the other side of the lower protective cover 510 and is wound up by the winding mechanism 400. The upper protective cover 520 and the lower protective cover 510 are then closed, covering the polishing mechanism 300. This prevents copper shavings generated during polishing from flying everywhere, thus preventing injury to personnel. The dust pump 570 draws the copper shavings into the slipway pipe 530 and the absorption pipe 540, where they enter the collection box 550 and are isolated and stored by the filter element 560, thereby preventing copper shavings accumulation. On the operating table, to reduce the workload of workers, copper shavings are cleaned and filter element 560 is replaced by rotating the box door 553. Rotating the filter element 560 causes the protrusion 561 to slide from the long side to the short side of the L-shaped groove 552. Pulling the filter element 560 causes the protrusion 561 to slide out along the short side of the L-shaped groove 552. After cleaning or replacing the filter element 560, the protrusion 561 on the filter element 560 is aligned with the short side of 512 and inserted into the long side of the L-shaped groove 552. Rotating the filter element 560 causes 562 to rotate to the innermost side of the long side of the L-shaped groove 552, thus fixing the filter element 560 in the connecting ring 551. This prevents copper shavings from accumulating on the operating table and reduces the workload of workers.

[0048] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
