[0033] Example 1:

[0034] like Figure 1 As shown, this embodiment provides a processing equipment for irregularly shaped copper strips, including an unwinding machine 1, a straightening machine 3, a copper strip cutting device 4, and a winding machine 5 arranged sequentially. The unwinding machine 1, the straightening machine 3, and the winding machine 5 all employ existing technology, so they will not be described in detail here. The straightening machine 3 can perform real-time alignment verification of the copper strip 2 to prevent positional deviation of the copper strip 2, which would affect the final cutting accuracy of the copper strip. Figure 2 As shown, the collimator 3 is equipped with a conveyor belt 42, which can provide some power for the transmission of the copper belt 2.

[0035] like Figure 3 As shown, the copper strip cutting device 4 includes a frame 41, and a conveyor belt 42 is arranged above the frame 41. It can also provide some power for the transmission of the copper strip 2, and can also work with the copper strip cutting device 4 to straighten the area of ​​the copper strip 2 to be cut, so as to ensure the cutting effect of the copper strip 2.

[0036] A side support plate 43 is provided on one side of the conveyor belt 42. A tool position adjustment assembly 44 is installed on the side support plate 43, and a tool assembly 45 is connected to the tool position adjustment assembly 44. The longitudinal height of the tool assembly 45 can be adjusted by the tool position adjustment assembly 44. A grating ruler 47 fixed on the side support plate 43 is connected to one side of the tool assembly 45. The grating ruler 47 can accurately record the displacement data of the tool assembly 45, which can significantly improve the adjustment accuracy of the tool position adjustment assembly 44 on the tool assembly 45, thereby effectively improving the cutting effect of the tool assembly 45 on the copper strip 2. The conveyor belt 42, the tool position adjustment assembly 44, and the grating ruler 47 are all electrically connected to a controller 48 fixed in the frame 41. Through the control of the controller 48, the efficient cooperation of the conveyor belt 42, the tool position adjustment assembly 44, and the grating ruler 47 can be achieved, thereby realizing stable and efficient cutting of the copper strip 2.

[0037] Among them, such as Figure 4 As shown, the tool position adjustment assembly 44 includes a mounting plate 441 fixed to a side support plate 43 for providing an installation position. A lead screw motor 442 is mounted on the mounting plate 441, and the lead screw motor 442 is vertically connected to a lead screw 443. The rotation of the lead screw motor 442 can drive the lead screw 443 to rotate in the forward or reverse direction. A lead screw slider 444 is mounted on the lead screw 443, and the rotation of the lead screw 443 can cause the lead screw slider 444 to move up and down on the lead screw 443.

[0038] The mounting plate 441 has a groove 445 corresponding to the position of the lead screw 443. A connecting block 446 is provided in the groove 445 and connected to the inner side of the lead screw slider 444. The other side of the connecting block 446 is fixed to the tool assembly 45 located on the other side of the mounting plate 441, so that the lead screw slider 444 can drive the tool assembly 45 to move up and down in the vertical direction, thereby realizing the function of the tool position adjustment component 44 to adjust the position of the tool assembly 45.

[0039] like Figure 5 As shown, the tool assembly 45 includes a tool frame 451, on the inner side of which a cutting head 452 is obliquely fixed. Screw holes 453 are correspondingly provided on the tool frame 451 and the cutting head 452, and the cutting head 452 is fixed with screws. The outer side of the tool frame 451 is connected to a tool position adjustment assembly 44 and a grating ruler 47, respectively, for precise control of the position of the inner cutting head 452.

[0040] The top and bottom sides of the cutter frame 451, as well as the side away from the side support plate 43, are all open structures. The front of the groove inside the cutter frame 451 is an inverted trapezoidal structure, which allows the bottom of the cutter frame 451 to work with the conveyor belt 42 below to provide a certain squeezing and fixing effect on the copper strip 2 during the cutting process, preventing the copper strip 2 from shifting due to resistance. At the same time, the top of the cutter frame 451 has a large opening along the direction of the cutting head 452, which can ensure that the cut copper strip can be smoothly discharged. In order to improve the durability of the cutting head 452, in this embodiment, a mounting groove is provided at the tip of the cutting head 452, and a detachable diamond cutter head 455 is fitted on the mounting groove. The diamond cutter head 455 is made of single crystal diamond or nano-polycrystalline diamond, which makes the cutting edge of the cutting head 452 sharp, with good wear resistance and cutting performance. The detachable installation method also facilitates the replacement of the diamond cutter head 455 later.

[0041] This embodiment also provides a method for using an irregularly shaped copper strip processing equipment, including the following steps:

[0042] S1. Install the copper strip on the unwinding and rewinding machines, ensuring that the copper strip is flat and tightly attached to the conveyor belt of the straightening machine and the copper strip cutting device, avoiding wrinkles and loosening.

[0043] S2. Set the processing data for the unwinding machine, collimator, copper strip cutting device, and winding machine respectively;

[0044] S3. The unwinding machine, collimator, copper strip cutting device and winding machine work simultaneously to process copper strip;

[0045] S4. Inspect the processed copper strip to determine if it meets the requirements; if it does not meet the requirements, adjust the tool assembly and processing data until it does.

[0046] In this embodiment, a copper strip cutting device 4 is used to cut the copper strip 2, such as... Figure 6 As shown, the specific operation during use is as follows:

[0047] (1) Copper strip preparation: In this embodiment, a copper strip 2 with a thickness of 1mm and a width of 80mm is selected. The material of the copper strip 2 conforms to relevant industry standards and has good ductility and conductivity. The copper strip 2 is installed on the unwinding machine 1 and the winding machine 5, and the copper strip 2 is passed through the straightening machine 3 and the copper strip cutting device 4 to ensure that the copper strip 2 is flat and tightly attached to the conveyor belt 42, avoiding wrinkles or loosening. During the installation process, a special clamp is used to fix the copper strip to ensure the stability of the copper strip during the processing.

[0048] (2) Tool Selection and Installation: In this embodiment, based on the processing width of 80mm and the requirements for processing thin copper strip, a suitable cutting head 452 is selected, and a corresponding diamond cutting head 455 is installed on the tip of the cutting head 452. The cutting head 452 is installed in the tool frame 451, and the installation is carried out according to the equipment operating procedures to ensure that the cutting head 452 is firmly installed and that the cutting edge of the diamond cutting head 455 is parallel to the processing surface of the copper strip 2. After installing the cutting head 452, a high-precision testing instrument is used to test the installation accuracy of the diamond cutting head 455 to ensure that the installation error of the diamond cutting head 455 is within the allowable range.

[0049] (3) Start-up and parameter adjustment of processing equipment: Turn on the unwinder 1 and the rewinder 5 to start the copper strip 2 on the processing equipment. The tool position adjustment component 44 is lowered in the Z-axis direction and the tool height is finely adjusted. The displacement distance is monitored by the grating ruler 47, and the cutting edge is accurately lowered by 0.5 mm, with the error controlled within ±0.003 mm. At the same time, the cutting speed is set to 10 m / min to perform stable cutting on the copper strip 2.

[0050] Before starting the processing equipment, a comprehensive inspection of all components, including the electrical system, transmission system, and lubrication system, should be conducted to ensure the equipment is in normal operating condition. During parameter adjustment, operators must strictly follow the operating procedures to ensure the accuracy of parameter settings.

[0051] Example 2:

[0052] In this implementation, two copper strip cutting devices 4 are used to cut the copper strip 2 simultaneously. The structural diagram of the combination of the two cutting heads 452 is shown below. Figure 7 As shown, two cutting heads 452 are fixedly placed sequentially along the copper strip's running direction (X direction), with their tool projections overlapping by 5mm in the copper strip's width direction (Y direction). The specific operation during use is as follows:

[0053] (1) Copper strip preparation: In this embodiment, a copper strip 2 with a thickness of 1mm and a width of 80mm is selected. The material of the copper strip 2 conforms to relevant industry standards and has good ductility and conductivity. The copper strip 2 is installed on the unwinding machine 1 and the winding machine 5, and the copper strip 2 is passed through the straightening machine 3 and the copper strip cutting device 4 to ensure that the copper strip 2 is flat and tightly attached to the conveyor belt 42, avoiding wrinkles or loosening. During the installation process, a special clamp is used to fix the copper strip to ensure the stability of the copper strip during the processing.

[0054] (2) Tool Selection and Installation: Based on the machining width of 35mm and the requirements for machining thin copper strip, two cutting heads 452 are selected, and a corresponding diamond cutting head 455 is installed at the tip of each cutting head 452. The cutting edge width of each diamond cutting head 455 is 20mm. The two cutting heads 452 are placed sequentially at a fixed interval along the copper strip running direction (X direction), with the tool projections overlapping by 5mm in the copper strip width direction (Y direction). The two cutting heads 452 are installed in the tool frames 451 of different copper strip cutting devices 4, and the installation is carried out according to the equipment operation procedures to ensure that the cutting heads 452 are firmly installed and that the cutting edge of the diamond cutting head 455 is parallel to the machining surface of the copper strip 2. After installing the cutting heads 452, the installation accuracy of the diamond cutting head 455 is tested using a high-precision testing instrument to ensure that the installation error of the diamond cutting head 455 is within the allowable range.

[0055] (3) Start-up and parameter adjustment of processing equipment: Turn on the unwinder 1 and the rewinder 5 to start the copper strip 2 on the processing equipment. The tool position adjustment component 44 is lowered in the Z-axis direction and the tool height is finely adjusted. The displacement distance is monitored by the grating ruler 47, and the cutting edge is accurately lowered by 0.5 mm, with the error controlled within ±0.003 mm. At the same time, the cutting speed is set to 10 m / min to perform stable cutting on the copper strip 2.

[0056] Before starting the equipment, a comprehensive inspection of all components should be conducted, including the electrical system, transmission system, and lubrication system, to ensure that the equipment is in normal operating condition. During parameter adjustment, operators must strictly follow the operating procedures to ensure the accuracy of parameter settings.

[0057] Example 3:

[0058] In this implementation, four copper strip cutting devices 4 are used simultaneously to cut the copper strip 2. The first three copper strip cutting devices 4 have cutting heads 452 installed in their tool frames 451. To ensure a smooth cutting surface, the fourth copper strip cutting device 4 uses a finishing tool 46. A schematic diagram of the combination of the three cutting heads 452 and the finishing tool 46 is shown below. Figure 8 As shown, three cutting heads 452 are placed sequentially at fixed intervals along the copper strip's running direction (X direction), with their tool projections overlapping by 5mm in the copper strip's width direction (Y direction), and a finishing tool 46 is positioned at the tail end. The specific operation during use is as follows:

[0059] (1) Copper strip preparation: In this embodiment, a copper strip 2 with a thickness of 1mm and a width of 80mm is selected.

During the installation process, a special clamp is used to fix the copper strip to ensure the stability of the copper strip during the processing.

[0060] (2) Tool Selection and Installation: Based on the processing requirements of a 50mm wide thin copper strip, three cutting heads 452 and one finishing tool 46 are selected.

The three cutting heads 452 and one finishing tool 46 are installed on different copper strip cutting devices 4, following the equipment operating procedures, ensuring that each tool is securely installed and that the cutting edge of the tool remains parallel to the processing surface of the copper strip 2. After all tools are installed, a high-precision testing instrument is used to check the installation accuracy of the tools to ensure that the installation error is within the allowable range.

[0061] (3) Equipment Start-up and Parameter Adjustment: Turn on the unwinder 1 and the rewinder 5 to start the copper strip 2 on the processing equipment. The tool position adjustment component 44 lowers in the Z-axis direction and finely adjusts the tool height. The displacement distance is monitored by the grating ruler 47, and the cutting edge is accurately lowered by 0.5 mm, with the error controlled within ±0.003 mm. At the same time, the cutting speed is set to 10 m / min to perform stable cutting and finishing of the copper strip 2.
