Description

Technical Field

[0001] This application relates to the field of copper strip processing technology, and in particular to an automated, high-precision grooving device for fuse melt material. Background Technology

[0002] In traditional fuses, the copper strip needs to be coated with silver during the manufacturing process. This allows the copper strip to melt quickly and cut off the circuit in case of overload or short circuit. This ensures the melting performance of the copper strip in the fuse, while the addition of silver also improves the fuse's oxidation resistance.

[0003] To attach silver to copper strip, it is usually necessary to process several through grooves evenly spaced along the length of the copper strip during its processing. These through grooves penetrate the copper strip along its thickness, and then the silver material is embedded within these grooves, thus achieving a preliminary combination of silver and copper strip. However, it has been found that using the above-mentioned method of creating through grooves can easily damage the overall performance of the copper strip. Therefore, in existing technology, a common approach is to create non-through grooves 501 on both sides of the copper strip's thickness direction. This ensures that the silver material is embedded on the surface of the copper strip while preserving its overall performance. The formed copper strip 50 is as follows: Figure 14 As shown.

[0004] Existing methods for creating attachment grooves on the surface of copper strip typically require specialized grooving equipment. A typical grooving device includes an unwinding machine, a winding machine, several support rollers, and a cutting roller equipped with a milling cutter. The cutting roller is positioned directly above one of the support rollers and can be raised and lowered. The copper strip passes between the cutting roller and the support roller. In operation, the copper strip to be processed is mounted on the unwinding machine. One end is then unwound and guided past several support rollers before being wound onto the winding machine. The cutting roller is then lowered to contact the upper surface of the copper strip, and the unwinding, winding, and cutting roller are started. During the unwinding and winding process, the rotation of the milling cutter achieves the purpose of grooving one side of the copper strip surface. After grooving, the coiled material is removed from the winding machine and remounted on the unwinding machine. The same process is then repeated to groove the other side of the copper strip surface, thus achieving the grooving process on both sides of the copper strip's thickness.

[0005] However, during the grooving process using the aforementioned equipment, the copper strip on the side away from the milling cutter is supported by a support roller. This roller contact is essentially just a line contact with the back of the copper strip, resulting in a weak load-bearing capacity. During the milling cutter's rotation and cutting process, force is applied to the surface of the copper strip, which can easily cause deformation of the copper strip on both sides of the grooving area. This affects the accuracy of the grooving on the copper strip and needs improvement. Summary of the Invention

[0006] In order to improve the grooving accuracy by increasing the support of the copper strip during the grooving process and avoiding deformation of some copper strips, this application provides an automated high-precision grooving device for fuse melt material.

[0007] This application provides an automated, high-precision grooving device for fuse element material, which adopts the following technical solution: An automated, high-precision fuse fusible material grooving device includes a winding machine, an unwinding machine, a machine base, and a roll material leveling mechanism, an auxiliary transmission mechanism, a waste chip cleaning mechanism, and a copper strip cutting mechanism mounted on the machine base; The copper strip cutting mechanism includes a guide roller mounted on the machine base, a cutting roller rotating on the machine base, a milling cutter mounted on the cutting roller, a first drive motor mounted on the machine base for driving the cutting roller to rotate, a support platform mounted on the machine base for supporting the copper strip, and a position adjustment component mounted on the support platform for driving the support platform itself closer to or further away from the milling cutter. The support platform is provided with a limiting component to ensure that the copper strip always fits against the support platform. The machine base is provided with a coolant delivery mechanism for cooling the copper strip during the processing.

[0008] By adopting the above technical solution, the position of the support platform is adjusted by the position adjustment component during use, so that the support platform abuts against the copper strip. On the one hand, the support platform and the copper strip are in surface contact, which ensures that the copper strip is more stable during the milling process and is conducive to improving the milling accuracy. On the other hand, the movement of the support platform, together with the limiting component, limits the copper strip, thereby changing the distance between the copper strip and the milling cutter, thus changing the depth of the milling groove on the copper strip. The overall use is simpler and more convenient, and the milling accuracy is higher than that of the line contact method in the prior art.

[0009] Preferably, both the copper strip cutting mechanism and the coolant delivery mechanism are provided in two sets, with the two sets of copper strip cutting mechanisms arranged at intervals along the copper strip transmission direction, and the coolant delivery mechanism and the copper strip cutting mechanism being arranged in a one-to-one correspondence.

[0010] By adopting the above technical solution, during use, through the cooperation of two sets of copper strip cutting mechanisms and coolant delivery mechanisms, when the copper strip is processed by the copper strip cutting mechanism, coolant can be dripped onto the copper strip through the coolant delivery mechanism, thereby achieving the purpose of cooling down the copper strip during the processing, which is more conducive to ensuring the milling process of the copper strip.

[0011] Preferably, the auxiliary transmission mechanism includes a mounting base, a drive roller that rotates on the mounting base, a first gear coaxially disposed at one end of the drive roller, a sliding block that slides on the mounting base, a driven roller that rotates on the sliding block, a second gear coaxially disposed at one end of the driven roller, and a second drive motor disposed on the mounting base. The first gear and the second gear mesh with each other. The drive roller and the driven roller respectively abut against both sides in the thickness direction of the copper strip. The second drive motor is used to drive the first gear to rotate.

[0012] By adopting the above technical solution, in use, the second drive motor drives the first gear to rotate, and the rotation of the first gear synchronously drives the second gear to rotate, thereby driving the drive roller and the driven roller to rotate synchronously in opposite directions. Then, the copper belt is driven to move by the contact between the drive roller and the driven roller and the copper belt.

[0013] Preferably, the guide roller includes a first roller body and a second roller body arranged coaxially. One end of the second roller body is slidably inserted into the first roller body. A first baffle is fixed to the end of the first roller body away from the second roller body. A second baffle is fixed to the end of the second roller body away from the first roller body. Both the first baffle and the second baffle are rotatably mounted on the machine base. The machine base is also provided with a spacing adjustment component for adjusting the distance between the first baffle and the second baffle.

[0014] By adopting the above technical solution, during use, the first baffle and the second baffle respectively abut and limit the two sides of the copper strip in the width direction, thereby preventing the copper strip from skewing during processing, thus avoiding changes in the milling groove position caused by the skewing of the copper strip, and ensuring the accuracy of milling groove; and by adjusting the distance between the second baffle and the first baffle by the spacing adjustment component, it can be adapted to copper strips of different widths, making it more practical.

[0015] Preferably, the material receiving platform includes a base body slidably disposed on the machine base, a support platform disposed on the base body, and a limiting block disposed on the support platform. The limiting block is used to limit the copper strip on both sides in the width direction. Two sets of limiting components are provided, and the two sets of limiting components are respectively disposed on both sides of the support platform. The position adjustment component is used to drive the base body to slide.

[0016] By adopting the above technical solution, the stability of the copper strip on the support platform is ensured through the cooperation of the limit block, the support platform, and the two sets of limit components, thereby ensuring the stability of the milling process and thus ensuring the milling accuracy.

[0017] Preferably, the position adjustment assembly includes a first lead screw that rotates on the base, a first handwheel fixed to the end of the first lead screw, a first threaded sleeve that is threadedly engaged with the first lead screw, and a first wedge block fixed to the first threaded sleeve. The first wedge block slides with the base. A base plate is fixed on the base, and a second wedge block is fixed on the base plate. The wedge surfaces of the first wedge block and the second wedge block abut against each other.

[0018] By adopting the above technical solution, in use, rotating the first handwheel drives the first lead screw to rotate, and the rotation of the first lead screw drives the first screw sleeve and the first wedge block to move. Thus, under the abutting engagement of the second wedge block with the first wedge block, the first wedge block slides along the axial direction of the first lead screw and gradually rises, thereby driving the copper strip to gradually approach the milling cutter, thereby realizing the adjustment of the position of the material receiving platform.

[0019] Preferably, the support platform includes a base mounted on the seat, a platform slidably mounted on the base, a second lead screw rotatably mounted on the base, a second handwheel for driving the second lead screw to rotate, a second threaded sleeve threaded with the second lead screw, and a third wedge block fixed on the second threaded sleeve. A fourth wedge block is fixed on the base, and the wedge surfaces of the third and fourth wedge blocks abut against each other. The sliding direction of the platform is parallel to the sliding direction of the seat, and the platform is used to support the copper strip.

[0020] By adopting the above technical solution, during use, the cooperation of the second lead screw, the second screw sleeve, the third wedge block, and the fourth wedge block enables fine-tuning of the table surface, thereby adjusting the depth of the milling groove on the copper strip in conjunction with the movement of the base. In addition, by adjusting the position of the table surface alone, in conjunction with the winding or unwinding machine to wind or unwind the copper strip, the position of the milling cutter on the copper strip can be adjusted, thereby achieving relative adjustment of the position of the double-sided milling groove on the copper strip. It is simple and convenient to use.

[0021] Preferably, the limiting component includes a mounting frame fixed on the support platform and a lower pressure roller that rotates on the mounting frame, the sidewall of the lower pressure roller abutting against the upper surface of the copper strip.

[0022] By adopting the above technical solution, the copper strip is pressed down without affecting the copper strip drive by setting the pressure roller, thereby ensuring that the copper strip always fits against the support table and thus ensuring the stability of the copper strip milling process.

[0023] Preferably, the support platform is slidably mounted on the base, the sliding direction of the support platform is parallel to the axial direction of the cutting roller, and the base is provided with a positioning structure for positioning the support platform.

[0024] By adopting the above technical solution, it is convenient for staff to slide the support platform away from the cutting roller during use, so as to maintain and clean the support platform; at the same time, the positioning structure ensures the stability of the support platform during use.

[0025] Preferably, the coolant delivery mechanism includes a delivery pipe, a control valve installed on the delivery pipe, and an outlet at one end of the delivery pipe. The end of the delivery pipe away from the outlet is connected to an external coolant pipeline. The control valve is used to control the opening and closing of the delivery pipe. The outlet is positioned towards the copper strip at the milling cutter machining area.

[0026] By adopting the above technical solution, during use, coolant is injected into the copper strip at the milling cutter's processing point through the coordinated use of the infusion pipe, outlet, and control valve, thereby achieving the purpose of cooling the copper strip during the processing and helping to ensure the quality of milling grooves on the copper strip.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The position of the support platform is adjusted by the position adjustment component so that the support platform abuts against the copper strip. On the one hand, the support platform and the copper strip are in surface contact, which ensures that the copper strip is more stable during the milling process and is conducive to improving the milling accuracy. On the other hand, the movement of the support platform, together with the limiting component, limits the copper strip, thereby changing the distance between the copper strip and the milling cutter, thus changing the depth of the milling groove on the copper strip. The overall use is simpler and more convenient. With the use of two sets of copper strip cutting mechanisms and waste chip cleaning mechanisms, the copper strip milling cutter is used for precision machining. Compared with the existing milling methods, the machining accuracy is higher. 2. The spacing between the first and second baffles is adjusted by the spacing adjustment component to ensure the contact limit of the copper strip in the width direction. Combined with the limit block on the support platform and the two sets of limit components, the stability and milling accuracy of the copper strip drive grooving process are further ensured. 3. By adjusting the position of the support platform in conjunction with the rotation of the second lead screw, the overall position of the support platform can be adjusted, as well as the platform surface can be finely adjusted. This achieves control over the milling depth of the copper strip and position adjustment of the slots on both sides of the copper strip. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 13 This application will be described in further detail.

[0031] This application discloses an automated, high-precision fuse melt material grooving device.

[0032] Reference Figure 1 An automated, high-precision grooving device for fuse melt material includes a winding machine 1, an unwinding machine 2, a base 3, a coil leveling mechanism 4, an auxiliary transmission mechanism 5, a waste cleaning mechanism 6, and a copper strip cutting mechanism 7. The unwinding machine 2 is located on the right side of the base 3, and the winding machine 1 is located on the left side of the base 3. In this application, both the unwinding machine 2 and the winding machine 1 are automatic winding machines. The coil leveling mechanism 4, the copper strip cutting mechanism 7, the waste cleaning mechanism 6, and the auxiliary transmission mechanism 5 are arranged alternately on the base 3 from right to left in a horizontal direction. A coolant conveying mechanism 31 is also provided on the base 3, and the coolant conveying mechanism 31 is arranged corresponding to the copper strip cutting mechanism 7.

[0033] Reference Figure 1 In use, since the copper strip 50 is usually stacked in rolls before processing, when it is necessary to process the rolled copper strip 50, the copper strip 50 to be processed is usually directly sleeved and fixed on the unwinding shaft of the unwinding machine 2. Since the rolled copper strip 50 itself will be bent, in order to straighten and flatten the bent copper strip 50, in this application, one end of the copper strip 50 needs to be stretched and threaded into the roll straightening mechanism 4. The roll straightening mechanism 4 is used to straighten and flatten the bent roll, thereby ensuring the accuracy of the subsequent roll milling groove. In this embodiment, the roll straightening mechanism 4 is preferably a fully automatic straightening machine.

[0034] Reference Figure 1 After the bent copper strip 50 is straightened by the coil straightening mechanism 4, it is then passed into the copper strip cutting mechanism 7. The copper strip cutting mechanism 7 then mills grooves on the upper surface of the copper strip 50. During the milling process, the waste debris generated on the copper strip 50 is cleaned and removed by the waste debris cleaning mechanism 6, thereby reducing the amount of waste debris adhering to the copper strip 50. After processing, the copper strip 50 passes through the auxiliary transmission mechanism 5 and is wound onto the winding shaft of the winding machine 1. During the above processing, the auxiliary transmission mechanism 5 assists in the continuous transmission of the copper strip 50, and in conjunction with the continuous winding of the winding machine 1 and the continuous unwinding of the unwinding machine 2, the purpose of milling grooves on the copper strip 50 can be achieved.

[0035] Reference Figure 1 In this application, in order to ensure the accuracy of milling, during the milling process on the copper strip 50, coolant needs to be injected into the copper strip 50 through the coolant delivery mechanism 31 to cool the copper strip 50. Therefore, two sets of copper strip cutting mechanism 7 and coolant delivery mechanism 31 are provided, and the two sets of copper strip cutting mechanism 7 are arranged at intervals along the transmission direction of copper strip 50. The transmission direction of copper strip 50 is parallel to the length direction of machine base 3. The two sets of coolant delivery mechanism 31 are arranged one-to-one with the two sets of copper strip cutting mechanism 7. That is, in use, the leveled copper strip 50 first enters the copper strip cutting mechanism 7 on the right for roughing, and then enters the copper strip cutting mechanism 7 on the left for finishing, thereby improving the accuracy of milling on the copper strip 50.

[0036] Reference Figure 1The coolant delivery mechanism 31 includes a delivery pipe 311, a control valve 312, and an outlet 313. The delivery pipe 311 is connected to an external coolant delivery pipeline. The control valve 312 is installed on the delivery pipe 311 and is used to control the opening and closing of the delivery pipe 311. The outlet 313 is installed at the end of the delivery pipe 311 away from the control valve 312, and the outlet 313 is set towards the copper strip 50 being processed by the milling cutter 73. In this embodiment, in order to facilitate the worker to adjust and fix the position of the outlet 313, the delivery pipe 311 is preferably made of a metal universal bamboo joint pipe. During use, through the cooperation of the delivery pipe 311, the control valve 312, and the outlet 313, coolant is continuously injected into the copper strip 50 being processed to cool the copper strip 50 and reduce the impact of the temperature rise of the copper strip 50 on the milling process.

[0037] Reference Figure 1 and Figure 2 The copper strip cutting mechanism 7 includes guide rollers 71, cutting rollers 72, milling cutters 73, a first drive motor 74, a material receiving platform 75, and a position adjustment assembly 76. Each set of copper strip cutting mechanisms 7 includes two guide rollers 71, and the two guide rollers 71 should be located on both sides of the cutting rollers 72. In this application, since the two sets of copper strip cutting mechanisms 7 are distributed at intervals along the horizontal direction, the guide rollers 71 set between the cutting rollers 72 in the two sets of copper strip cutting mechanisms 7 can be shared. That is to say, in this application, three guide rollers 71 are set in the two sets of copper strip cutting mechanisms 7, and one cutting roller 72 is set between every two guide rollers 71.

[0038] Reference Figure 2 and Figure 3 The guide roller 71 is composed of a first roller body 711 and a second roller body 712, which are coaxially arranged. A first baffle 713 is fixedly connected to one end of the first roller body 711, and the other end of the first roller body 711 is slidably fitted with one end of the second roller body 712. A second baffle 714 is fixedly connected to the end of the second roller body 712 away from the first roller body 711. Two bearing seats 715 are provided on the machine base 3, which are arranged opposite to each other. One bearing seat 715 is fixed to the machine base 3 by bolts, and the other bearing seat 715 is slidably arranged on the machine base 3. The guide roller 71 is located between the two bearing seats 715, and the first baffle 713 is rotatably connected to the fixed bearing seat 715 by a bearing, and the second baffle 714 is rotatably connected to the slidably arranged bearing seat 715 by a bearing.

[0039] Reference Figure 2 and Figure 3A spacing adjustment assembly 32 is also provided on the machine base 3. The spacing adjustment assembly 32 includes a bearing seat 715 for sliding, thereby adjusting the spacing between the first baffle 713 and the second baffle 714. The spacing adjustment assembly 32 includes an adjusting screw 321 threadedly connected to the machine base 3 and an adjusting handwheel provided at one end of the adjusting screw 321. The other end of the adjusting screw 321 passes through the machine base 3 and is rotatably connected to the slidingly disposed bearing seat 715. In use, the worker can drive the adjusting screw 321 to rotate by rotating the adjusting handwheel, thereby causing the adjusting screw 321 to slide along its own axial direction, thereby driving the bearing seat 715 connected to the second baffle 714 and the second baffle 714 to slide together. This allows the distance between the second baffle 714 and the first baffle 713 to be adjusted. This ensures that the first baffle 713 and the second baffle 714 can abut against both sides of the copper strip 50 in the width direction when processing copper strips 50 of different widths, so as to ensure that the copper strip 50 will not be skewed during transmission.

[0040] Reference Figure 2 and Figure 4 A support block 35 is bolted to the base 3. The support block 35 is arranged in a Z-shape. One end of the cutting roller 72 is rotatably connected to the end of the support block 35, and the other end of the cutting roller 72 is rotatably mounted on the base 3. The milling cutter 73 is sleeved on the cutting roller 72 and is keyed to the cutting roller 72. The first drive motor 74 is bolted to the base 3, and the output shaft of the first drive motor 74 is coaxially fixed to the cutting roller 72. In use, the first drive motor 74 drives the cutting roller 72 to rotate, thereby driving the milling cutter 73 to rotate. The rotation of the milling cutter 73, in conjunction with the transmission of the copper strip 50, achieves the purpose of slotting on the copper strip 50.

[0041] Reference Figure 2 and Figure 4 In this application, a plurality of milling cutters 73 are provided, and the plurality of milling cutters 73 are arranged in a linear array along the axial direction of the cutting roller 72. A separator ring 731 is provided between two adjacent milling cutters 73, and the thickness of the separator ring 731 is the spacing between the two adjacent milling cutters 73. A separator ring 731 is also provided on the outer side of the two milling cutters 73 located at both ends of the cutting roller 72. The separator ring 731 is fixed to the cutting roller 72 by bolts, thereby forming a clamping and fixing of the intermediate milling cutter 73 and the separator ring 731. In use, the spacing between the two milling cutters 73 can be changed by adjusting the thickness of the separator ring 731, thereby changing the spacing of the slots along the width direction of the copper strip 50.

[0042] Reference Figure 2 and Figure 5The material support platform 75 is located below the cutting roller 72. The material support platform 75 can slide closer to or further away from the cutting roller 72. The material support platform 75 is used to support the copper strip 50. In this application, the material support platform 75 consists of a base 751, a support platform 752, and a limiting block 753. One end of the base 751 is slidably connected to the machine base 3 in the vertical direction, and the other end of the base 751 is suspended. The length direction of the base 751 is parallel to the axial direction of the cutting roller 72. The support platform 752 is set on the base 751, and the length direction of the support platform 752 is parallel to the length direction of the base 751. Two sets of limiting blocks 753 are provided. The two sets of limiting blocks 753 are symmetrically arranged along the length direction of the support platform 752. Each set of limiting blocks 753 slides along the length direction of the support platform 752. Abutment bolt is threaded onto the limiting block 753. One end of the abutment bolt passes through the limiting block 753 and abuts against the support platform 752.

[0043] Reference Figure 2 and Figure 5 Meanwhile, to ensure the normal transmission of the copper strip 50, guide slopes are formed at both ends of the support table 752 in the width direction. During use, the support table 752 makes surface contact with the lower surface of the copper strip 50 to ensure stable support for the copper strip 50, thereby ensuring the accuracy of the milling cutter 73 in the processing of the copper strip 50. During the transmission of the copper strip 50, the limit block 753 is used to limit the two sides of the copper strip 50 to prevent the transmission of the copper strip 50 from being skewed when under force during the milling process. With the setting of the guide roller 71, the transmission direction of the copper strip 50 is ensured. The sliding setting of the limit block 753, together with the abutment bolt, can be adapted to copper strips 50 of different widths, thus expanding the overall applicability.

[0044] Reference Figure 5 and Figure 6 To ensure that the copper strip 50 remains in contact with the support platform 752 during transmission, a limiting component 77 is provided on the support platform 752. Two sets of limiting components 77 are provided, and the two sets of limiting components 77 are arranged opposite each other on both sides of the width direction of the support platform 752. In this application, the limiting component 77 includes a mounting frame 771 and a lower pressure roller 772. Two mounting frames 771 are provided, and the two mounting frames 771 are symmetrically arranged along the length direction of the support platform 752. The mounting frames 771 are fixed to the side wall of the support platform 752 by bolts. The two ends of the lower pressure roller 772 are rotatably connected to one mounting frame 771 respectively along its length direction. In this application, to ensure that the copper strip 50 remains in contact with the support platform 752, the lowest point of the lower pressure roller 772 should be lower than the support surface of the support platform 752. The lower pressure roller 772 can limit and guide the copper strip 50 without affecting its transmission.

[0045] Reference Figure 5 and Figure 6The support platform 752 is slidably disposed on the base 751 along the length direction of the base 751. A positioning structure is provided on the base 751 to position the slidable support platform 752 to prevent relative sliding between the support platform 752 and the base 751 during the process of the support platform 752 abutting against the copper strip 50, thereby avoiding affecting the transmission of the copper strip 50. In this application, the positioning structure is set as a positioning plate 754. Two positioning plates 754 are provided, and the two positioning plates 754 are symmetrically arranged on both sides of the width direction of the support platform 752. One end of the positioning plate 754 is fixed to the base 751 by bolts, and the other end of the positioning plate 754 is fixed to the support platform 752 by bolts.

[0046] Reference Figure 5 and Figure 6 In the initial state, the support platform 752 is located directly below the cutting roller 72. At this time, the two ends of the positioning plate 754 are bolted to the side walls of the support platform 752 and the base 751, respectively, so as to achieve the relative positioning of the support platform 752 and the base 751. When the copper strip 50 is processed and maintenance or cleaning of the support platform 752 is required, simply unscrew the bolts connecting the positioning plate 754 and the support platform 752, and then pull the support platform 752 away from the machine base 3, thereby sliding the support platform 752 as a whole outside the cutting roller 72 for easy maintenance and cleaning. The overall use is simple and convenient.

[0047] Reference Figure 5 and Figure 7 The position adjustment component 76 is used to drive the seat 751 to rise and fall. The position adjustment component 76 includes a first lead screw 761, a first handwheel 762, a first threaded sleeve, and a first wedge block 763. The first lead screw 761 is rotatably mounted on the seat 751, and one end of the first lead screw 761 is located outside the seat 751. The first handwheel 762 is mounted on the end of the first lead screw 761 located outside the seat 751. The first threaded sleeve is threadedly engaged with the first lead screw 761. The first wedge block 763 is fixedly connected to the first threaded sleeve, and the first wedge block 763 is slidably engaged with the seat 751. A base plate 33 is also fixedly mounted on the base 3. The base plate 33 is located below the seat 751. A second wedge block 34 is fixedly connected to the base plate 33. The wedge-shaped surface of the second wedge block 34 abuts against the wedge-shaped surface of the first wedge block 763.

[0048] Reference Figure 5 and Figure 7In use, when the worker turns the first handwheel 762, the first lead screw 761 will be driven to rotate, thereby driving the first threaded sleeve and the first wedge block 763 to slide along the axial direction of the first lead screw 761. When the first wedge block 763 slides, under the abutting cooperation of the second wedge block 34, the first wedge block 763 drives the seat body 751 to move upward, thereby driving the entire material receiving table 75 to rise, so as to achieve the purpose of driving the copper strip 50 to gradually approach the milling cutter 73. In this way, the height position of the copper strip 50 can also be controlled, thereby adjusting the depth of the milling groove on the upper surface of the copper strip 50.

[0049] Reference Figure 1 and Figure 8 The auxiliary transmission mechanism 5 is used to ensure the continuous and stable transmission of the copper strip 50 during the milling process. The auxiliary transmission mechanism 5 includes a mounting base 51, a drive roller 52, a first gear 53, a sliding block 54, a driven roller 55, a second gear 56, and a second drive motor 57. The mounting base 51 is fixedly mounted on the machine base 3. The drive roller 52 is rotatably mounted on the mounting base 51. One end of the drive roller 52 passes through the mounting base 51 and is coaxially fixedly connected to the first gear 53. The sliding block 54 is slidably mounted on the mounting base 51 in the vertical direction. An adjusting screw 58 for adjusting the position of the sliding block 54 is provided on the mounting base 51. One end of the adjusting screw 58 is rotatably connected to the sliding block 54, and the other end of the adjusting screw 58 passes through the mounting base 51. The driven roller 55 is rotatably mounted on the sliding block 54, and one end of the driven roller 55 passes through the sliding block 54 and is coaxially fixedly connected to the second gear 56.

[0050] Reference Figure 1 and Figure 8 The driven roller 55 has its axis parallel to the axis of the drive roller 52, and is located directly above the drive roller 52. The second gear 56 meshes with the first gear 53. The second drive motor 57 is mounted on the mounting base 51, and the output shaft of the second drive motor 57 is fixedly connected to the drive roller 52 through a universal coupling. In use, the copper strip 50 passes between the drive roller 52 and the driven roller 55, and the drive roller 52 and the driven roller 55 abut against the upper and lower surfaces of the copper strip 50, respectively. When the second drive motor 57 drives the drive roller 52 to rotate, the driven roller 55 rotates synchronously in the opposite direction under the cooperation of the first gear 53 and the second gear 56, thereby continuously conveying the copper strip 50 forward through the driven roller 55 and the drive roller 52. In order to ensure stable transmission of the copper strip 50 by the driven roller 55 and the drive roller 52, rubber anti-slip sleeves are provided on both the driven roller 55 and the drive roller 52.

[0051] Reference Figure 1 and Figure 9After the copper strip 50 is processed, before winding the copper strip 50, it is necessary to clean the waste in the non-penetrating groove 501 on the copper strip 50. Therefore, in this application, the waste cleaning mechanism 6 needs to be set between the copper strip cutting mechanism 7 and the auxiliary transmission mechanism 5 on the left side. The waste cleaning mechanism 6 includes a ventilation pipe 61 installed on one side of the mounting base 51 and a number of air nozzles 62 set on the ventilation pipe 61. In this embodiment, one end of the ventilation pipe 61 is connected to an external air supply pipe, and the number of air nozzles 62 are spaced apart along the axis of the ventilation pipe 61 and are facing the copper strip 50. When in use, high-pressure air is introduced into the ventilation pipe 61 through the external air supply pipe, and then sprayed out from the number of air nozzles 62 to blow away the waste remaining on the copper strip 50, thereby achieving the removal of waste.

[0052] Reference Figure 1 In addition, a waste chip collection groove 36 is provided on the base 3 corresponding to the two sets of copper strip cutting mechanisms 7 to collect the waste chips generated during the milling process of the copper strip 50.

[0053] The implementation principle of this application embodiment is as follows: In use, the bent copper strip 50 is first straightened and leveled by the coil leveling mechanism 4. After being guided and limited by the guide roller 71, the copper strip 50 passes through the lower pressure roller 772, two sets of material receiving platforms 75, and the auxiliary transmission mechanism 5 in sequence before being wound onto the winding roller of the winding machine 1. Then, the position adjustment component 76 drives the material receiving platform 75 to move upward as a whole, bringing the copper strip 50 closer to the milling cutter 73, thereby controlling the depth of the milling groove on the copper strip 50. Then, through the joint cooperation of the unwinding machine 2, the winding machine 1, and the auxiliary transmission mechanism 5, the copper strip 50 is continuously driven. During the transmission of the copper strip 50, after being guided and limited by the guide roller 71, the leveled copper strip 50 is first milled by the first set of copper strip cutting mechanisms 7. During the milling process, the setting of the lower pressure roller 772 ensures that the copper strip 50 is always in contact with the material receiving platform 75, thereby providing support force through the surface contact of the material receiving platform 75 with the copper strip 50. To ensure the stability of the copper strip 50 during the high-speed rotation of the milling cutter 73 in grooving the upper surface of the copper strip 50, coolant is continuously supplied to the surface of the copper strip 50 through the coolant delivery mechanism 31 to cool the processed copper strip 50. After cooling, the copper strip 50 completes rough machining and continues to be driven into the second set of copper strip cutting mechanisms 7. After the same machining process as the rough machining, the finishing machining is completed. Then, the waste chip cleaning mechanism 6 blows away the waste chips in the non-penetrating groove 501 on the copper strip 50 and guides the copper strip 50 to continue to be driven through the auxiliary transmission mechanism 5 until it is wound up by the winding machine 1. After the grooving operation on the front side of the copper strip 50 is completed, the copper strip 50 roll on the winding machine 1 is removed and reinstalled on the unwinding machine 2. Then, the copper strip 50 is passed through the grooving equipment with the reverse side facing up, so that the reverse side of the copper strip 50 is grooved with manual assistance, thereby achieving the purpose of grooving both sides of the copper strip 50 in the thickness direction.

[0054] Example 2: Reference Figure 10 The difference between this embodiment and Embodiment 1 is that, in this embodiment, the support platform 752 is composed of a base 7521, a platform 7522, a second lead screw 7523, a second handwheel 7524, a second threaded sleeve, and a third wedge block 7525. The base 7521 is slidably connected to the seat body 751, the platform 7522 is slidably mounted on the base 7521 in a vertical direction, the second lead screw 7523 is rotatably connected to the base 7521, and the second handwheel 7524 is installed at one end of the second lead screw 7523. The handwheel 7524 is used to drive the second lead screw 7523 to rotate. The second threaded sleeve is threadedly engaged with the second lead screw 7523. The third wedge block 7525 is fixedly connected to the second threaded sleeve, and the third wedge block 7525 slides with the table surface 7522. A fourth wedge block 7526 is fixedly installed on the base 7521. The wedge surface of the fourth wedge block 7526 and the wedge surface of the third wedge block 7525 abut against each other. The table surface 7522 is used to abut against the support copper strip 50. The mounting bracket 771 is fixed on the base 7521.

[0055] Reference Figure 10 In use, the second handwheel 7524 is turned to drive the second lead screw 7523 to rotate. The rotation of the second lead screw 7523 drives the second screw sleeve and the third wedge block 7525 to slide synchronously. With the cooperation of the fourth wedge block 7526, the table 7522 can be driven to rise and fall vertically, thereby realizing the fine adjustment of the distance between the copper strip 50 and the milling cutter 73. In addition, with the position adjustment component 76 driving the entire material receiving table 75 to rise and fall, the depth of the groove on the copper strip 50 can be adjusted.

[0056] Reference Figure 10 After the copper strip 50 has completed front grooving and before grooving the reverse side, keep the seat 751 in place and rotate the second handwheel 7524 to make a slight adjustment to the table 7522, thereby changing the height difference between the table 7522 and the lower pressure roller 772. This changes the position of the copper strip 50 passing through the milling cutter 73 under the same copper strip 50 winding method, thereby achieving relative adjustment of the grooving positions on both sides of the copper strip 50 in the thickness direction, making them misaligned to meet different processing requirements. Then, adjust the height of the receiving table 75 as a whole to ensure that the grooving depth on both sides of the copper strip 50 is the same. The overall operation is simple and convenient.

[0057] Example 3: Reference Figure 11The difference between this embodiment and Embodiment 1 is that there is a height difference between the two sets of copper strip cutting mechanisms 7 in the vertical direction, and the copper strip cutting mechanism 7 on the right is higher than the copper strip cutting mechanism 7 on the left. In addition, in this embodiment, a total of five guide rollers 71 are provided, and the five guide rollers 71 are staggered in the height direction to guide the copper strip 50 to pass through the copper strip cutting mechanism 7 on the left first, then through the copper strip cutting mechanism 7 on the right, and then through the auxiliary transmission mechanism 5, and finally through the winding machine 1 for winding. The position of the guide rollers 71 needs to ensure that, in the same set of copper strip cutting mechanisms 7, after the copper strip 50 is processed by the bottom end of the milling cutter 73, it can pass through the upper end of the milling cutter 73 again, so as to be processed by the upper end of the milling cutter 73 for secondary processing.

[0058] Reference Figure 12 and Figure 13 To ensure that the copper strip 50 can be simultaneously cut by both ends of a milling cutter 73 during the winding process, a lower pressure plate 8 is slidably connected to the support block 35. The lower pressure plate 8 slides vertically and provides support for the copper strip 50 at the upper end of the milling cutter 73, thereby ensuring the stability of the copper strip 50 during the milling process. Tension rollers 9 are rotatably installed on both sides of the lower pressure plate 8 to ensure that the copper strip 50 always adheres to the bottom surface of the lower pressure plate 8 after winding. Vertical folding plates 10 are integrally formed at both ends of the lower pressure plate 8 in the width direction. A transverse connecting plate 20 is also provided above the lower pressure plate 8. The top ends of the two vertical folding plates 10 are fixed to one end of the transverse connecting plate 20 by bolts. That is, the transverse connecting plate 20 and the lower pressure plate 8 are installed together by the two vertical folding plates 10, and an avoidance groove is formed between the transverse connecting plate 20 and the lower pressure plate 8.

[0059] Reference Figure 12 and Figure 13 A longitudinal support plate 30 is installed inside the clearance groove. Both ends of the longitudinal support plate 30 are fixed to the support block 35. The longitudinal support plate 30 and the transverse connecting plate 20 are arranged in a cross-shaped arrangement. A third lead screw 37 is rotatably connected to the support block 35. A fifth wedge block 201 is fixed to the bottom end of the transverse connecting plate 20. A sixth wedge block 301 is slidably arranged on the longitudinal support plate 30. The wedge surfaces of the fifth wedge block 201 and the sixth wedge block 301 abut against each other. A third threaded sleeve is fixed on the sixth wedge block 301. The third threaded sleeve is threadedly engaged with the third lead screw 37. In this embodiment, there are two sets of both the fifth wedge block 201 and the sixth wedge block 301. The two sets of sixth wedge blocks 301 are spaced apart along the axis of the third lead screw 37. The positions of the fifth wedge block 201 and the sixth wedge block 301 correspond one-to-one.

[0060] Reference Figure 12 and Figure 13To facilitate the rotation of the third lead screw 37, a third handwheel 38 is provided at one end of the third lead screw 37 that extends out of the support block 35. In addition, a buffer 40 is provided between the longitudinal support plate 30 and the transverse connecting plate 20. The buffer 40 is used to provide buffering during the process of the transverse connecting plate 20 driving the lower pressure plate 8 to descend as a whole, so as to ensure its lifting and lowering stability. The buffer 40 consists of a sleeve 401 fixed on the longitudinal support plate 30, a sliding rod 402 fixed on the bottom of the transverse connecting plate 20, and a compression spring 403 sleeved on the sliding rod 402. One end of the sliding rod 402 is slidably engaged with the sleeve 401, one end of the compression spring 403 abuts against the top of the sleeve 401, and the other end of the compression spring 403 abuts against the bottom wall of the transverse connecting plate 20.

[0061] Reference Figure 12 and Figure 13 In use, the worker drives the third lead screw 37 to rotate by turning the third handwheel 38. Under the action of the third screw sleeve, the sixth wedge block 301 and the third screw sleeve move synchronously along the axis of the third lead screw 37, thereby driving the fifth wedge block 201, the transverse connecting plate 20 and the lower pressure plate 8 to rise and fall as a whole, thereby adjusting the height of the copper strip 50 to ensure that the copper strip 50 can be grooved by the upper end of the milling cutter 73 when it passes over the upper end of the milling cutter 73. During the raising and lowering of the lower pressure plate 8, the tension roller 9 ensures that the copper strip 50 always fits against the lower pressure plate 8, thereby ensuring the stability of the copper strip 50 during the milling process of the upper end of the milling cutter 73.

[0062] The implementation principle of this application embodiment is as follows: In use, the bent copper strip 50 is first straightened and leveled by the coil leveling mechanism 4. After being guided and limited by the first guide roller 71 and the second guide roller 71, the copper strip 50 first passes through the lower pressure roller 772 and the material support table 75 in the left copper strip cutting mechanism 7. Then it goes up and passes around the first set of tension rollers 9 and passes between the lower pressure plate 8 and the milling cutter 73. After being guided and limited by the third guide roller 71, it passes through the lower pressure roller 772 and the material support table 75 in the right copper strip cutting mechanism 7. Then it continues to go up and passes around the second set of tension rollers 9 and passes between the second set of lower pressure plate 8 and the milling cutter 73. Finally, after being guided by the cooperation of the fourth guide roller 71 and the fifth guide roller 71, it is wound onto the winding roller of the winding machine 1 through the auxiliary transmission mechanism 5. Then, the position adjustment component 76 adjusts the material receiving platform 75, which corresponds to a portion of the copper strip 50, to move upwards, causing the copper strip 50 to move closer to the lower end of the milling cutter 73. Through the cooperation of the third handwheel 38 and the third lead screw 37, the lower pressure plate 8 drives a portion of the copper strip 50 to move downwards, only approaching the upper end of the milling cutter 73. Then, through the joint cooperation of the unwinding machine 2, the winding machine 1, and the auxiliary transmission mechanism 5, the copper strip 50 is continuously driven. During the transmission process of the copper strip 50, the leveled copper strip 50 first passes through the lower end of the left-side milling cutter 73 to process the front side of the copper strip 50. After rough machining, the copper strip 50 is finished by the upper end of the left end mill 73. Then, it is continuously driven to the position of the right end mill 73, so that the copper strip 50 is rough machined by the bottom end of the right end mill 73 and finished by the top end of the right end mill 73. After that, it enters the auxiliary transmission mechanism 5 and the waste chip cleaning mechanism 6 blows away the waste chips in the non-penetrating groove 501 on the copper strip 50 until it is wound up by the winding machine 1. This achieves the purpose of grooving both sides of the copper strip 50 in the thickness direction.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
