Description

[0001] This invention belongs to the field of copper foil cutting technology, specifically, it relates to a cutting device for cutting copper foil of different thicknesses. Background Technology

[0002] Copper foil has excellent electromagnetic shielding properties and is widely used in electronics, communications, and medical fields. The production of copper foil typically requires edge trimming. Since copper foil varies in size during production, the thickness of the cut must be controlled during the trimming process.

[0003] Existing copper foil cutting devices have been found to have several drawbacks during use. After the copper foil is cut, the waste material remains on the base, requiring the operator to clean it with a brush. This necessitates manual cleaning after each cut, making the process cumbersome. Furthermore, the operator needs to clamp and fix both ends of the cutting position during the cutting process to prevent displacement, but this requires unlocking after each cut, again complicating the operation and hindering efficiency. Additionally, the cutting blade must be manually moved onto the copper foil before cutting to ensure smooth operation, which is also inconvenient.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following advantages: By incorporating a shifting lead screw, the position of the entire cutting blade can be changed, thereby adjusting the cutting thickness. The rotation of the lead screw also causes the sliding sleeve and positioning sleeve to move horizontally. The positioning rod on the positioning sleeve slides along the shifting groove. When the positioning rod reaches the lower part of the shifting groove, the synchronously connected cutting motor and cutting blade can move downwards, automatically moving towards the copper foil, achieving automatic feeding and making operation more convenient. Furthermore, when the positioning rod reaches the top of the shifting groove, the cutting blade can automatically move upwards, separating the copper foil and facilitating subsequent unloading and loading operations, further simplifying the operation.

[0019] By incorporating a pressing sleeve and a reset cover, the positioning rod moves downward along the shifting groove, pulling the overlapping plate downward. The overlapping plate then moves the pressing rod and pressing plate downward, pressing the outer side of the cutting position, achieving automatic positioning and simplifying operation. When the positioning rod moves the pressing rod upward to the top, the positioning press can be unlocked, leaving the cut scrap copper foil in a non-positioned state. The upward movement of the pressing rod changes the position of the guide protrusion, causing the reset spring to move the reset rod outward. This, in turn, pushes the strip rod to rotate via the synchronous rod, which in turn rotates the flipping plate. Finally, the flipping plate holding the scrap copper foil flips at a certain angle, allowing the scrap to slide smoothly, achieving automatic unloading and simplifying operation, thus improving cutting efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0024] like Figures 1 to 9 As shown, a cutting device for cutting copper foil of different thicknesses includes a substrate 1, a shifting lead screw 2, a pressing sleeve 4, and a reset cover 5; copper foil is disposed on the substrate 1.

[0025] A shifting lead screw 2 is rotatably mounted on a base plate 1, and a push plate 22 is meshed on the shifting lead screw 2. A cutting lead screw 3 is mounted on the push plate 22, and a drive motor 313 is installed at the end of the cutting lead screw 3. A sliding sleeve 31 is meshed on the cutting lead screw 3, and a positioning sleeve 32 is installed on the sliding sleeve 31. A positioning rod 321 is inserted into the positioning sleeve 32. A shifting plate 34 is mounted on the base plate 1, and a shifting groove 342 is formed on the shifting plate 34. The shifting groove 342 is recessed towards the base plate 1, and the shifting groove 342 and the positioning rod 321 are slidably connected. A mounting bracket 33 is installed on the positioning rod 321, and a cutting motor 331 is installed on the mounting bracket 33. A cutting blade 332 is installed at the output end of the cutting motor 331. Shaft 3 is used to drive the cutting motor 331 to slide along the shifting groove 342 and cut the copper foil. The shifting screw shaft can drive the position of the entire cutting blade to change, thereby adjusting the cutting thickness. The rotation of the cutting screw shaft drives the entire sliding sleeve and positioning sleeve to move horizontally. The positioning rod on the positioning sleeve slides along the shifting groove. When the positioning rod moves to the low point of the shifting groove, the synchronously connected cutting motor and cutting blade can move downward and automatically move towards the copper foil, which can achieve the purpose of automatic feeding and make the operation more convenient. When the positioning rod moves to the top of the shifting groove, the cutting blade can automatically move upward and separate the copper foil, which facilitates the subsequent unloading and loading operations and makes the operation simpler.

[0026] The pressing sleeve 4 is installed above the substrate 1. A pressing rod 42 is movably inserted inside the pressing sleeve 4, and a pressing spring 412 is provided between the pressing rod 42 and the pressing sleeve 4. A pressing plate 423 is installed at the bottom of the pressing rod 42, and the pressing plate 423 corresponds to the substrate 1. An overlapping plate 422 is installed on the side wall of the pressing rod 42. The overlapping plate 422 and the positioning rod 321 are slidably connected. The positioning rod 321 is used to drive the pressing plate 423 to clamp and lock the copper foil. When the positioning rod moves down along the shifting groove, the positioning rod pulls the overlapping plate down. The overlapping plate drives the pressing rod and the pressing plate to move down. The pressing plate presses the outside of the cutting position, achieving the purpose of automatic positioning and making the operation simpler.

[0027] A synchronizing rod 52 is inserted inside the reset cover 5. The end of the synchronizing rod 52 is slidably connected to the guide protrusion 514 installed on the side wall of the pressing rod 42. A reset spring 512 is installed between the reset cover 5 and the synchronizing rod 52. Synchronizing rods 52 are installed on both sides of the synchronizing rod 52. A strip rod 521 is slidably installed on the synchronizing rod 52. A flipping plate 53 is installed at the rotation center of the strip rod 521. The flipping plate 53 is vertically aligned with the pressing plate 423. The pressing rod 42 is used to drive the flipping plate 53 to flip and unload the material. When the positioning rod drives the pressing rod to move upward to the top, the positioning press can be unlocked, so that the cut waste copper foil is in a non-positioned state. At this time, the upward movement of the pressing rod changes the position of the guide protrusion, which in turn causes the reset spring to drive the entire reset rod to move outward. The synchronizing rod pushes the strip rod to rotate, and the strip rod drives the flipping plate to rotate. Finally, the flipping plate with the waste copper foil flips at a certain angle, allowing the waste to slide down smoothly, achieving the purpose of automatic unloading, making the operation simpler and improving the cutting efficiency.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in a specific embodiment, a cutting notch 12 is provided on the substrate 1, and a flip plate 53 is rotatably installed on the side wall of the cutting notch 12. A gap is left between the flip plate 53 and the side wall of the cutting notch 12. A guide plate 121 is installed at the bottom of the cutting notch 12. The guide plate 121 is in an inclined state. The cutting notch 12 facilitates the movement of the cutting blade inside, and the guide plate 121 facilitates the subsequent sliding of waste materials.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a collection box 11 is further installed at the bottom of the substrate 1. An observation window 111 is installed on one side wall of the collection box 11, and a drawer 112 is movably inserted into the other side wall of the collection box 11. A handle 113 is installed on the drawer 112, and an anti-slip sleeve is provided on the handle 113. The feed port on the side wall of the collection box 11 corresponds to the end of the guide plate 121. Waste materials sliding off the guide plate 121 can fall onto the drawer 112 in the collection box 11. Later, the drawer 112 can be moved by pulling the handle 113 to clean the waste materials inside the drawer 112. Example

[0030] The difference between the above embodiments and this embodiment is that: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a mounting groove 13 is provided on the substrate 1, and the shifting lead screw 2 moves through the mounting groove 13. A crank 21 is installed at the end of the shifting lead screw 2, and a push plate 22 is slidably disposed on the mounting groove 13. A cover plate 131 covers the center of the mounting groove 13. The crank 21 drives the shifting lead screw 2 to rotate, and the shifting lead screw 2 drives the push plate 22 to slide in the mounting groove 13. The position of the mounting seat 221 on the push plate 22 moves synchronously, which in turn drives the cutting lead screw 3 to move. At this time, the positions of the cutting motor 331 and the cutting blade 332 on the cutting lead screw 3 change, thereby changing the cutting position of the copper foil and achieving the purpose of changing different cutting thicknesses. A pair of support legs 14 are fixedly mounted on the bottom of the base plate 1. Reinforcing ribs 141 are installed between the support legs 14 in a crisscross pattern. The support legs 14 serve a supporting purpose. A pair of mounting seats 221 are mounted on the push plate 22. The cutting screw shaft 3 is rotatably mounted on the mounting seats 221. The side wall of the mounting seat 221 is connected to the housing of the drive motor 313. A slide rod 312 is installed through the mounting seat 221. A slide block 311 is slidably mounted on the slide rod 312. The slide block 311 and the bottom of the slide sleeve 31 are connected to each other. When the drive motor 313 is started, it drives the cutting screw shaft 3 connected to the output shaft to rotate. The slide sleeve 31 is engaged on the cutting screw shaft 3, and the slide block 311 on the slide sleeve 31 can slide and limit the movement on the slide rod 312. Therefore, when the cutting screw shaft 3 moves, the entire slide sleeve 31 can slide on the cutting screw shaft 3.

[0031] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, in a specific embodiment, a connecting rod 322 is installed on the positioning rod 321. One end of the connecting rod 322 movably passes through the displacement groove 342, and the other end of the connecting rod 322 is connected to the mounting bracket 33. A limiting plate 323 is installed at the end of the connecting rod 322. The diameter of the limiting plate 323 is larger than the width of the displacement groove 342. A vertical rod 341 is installed at the bottom of the displacement plate 34, and the vertical rod 341 is connected to the surface of the base plate 1. The positioning sleeve 32 and the positioning rod 321 on the sliding sleeve 31 move with the sliding sleeve 31. At this time, the connecting rod 322 on the positioning rod 321 slides along the displacement groove 342 on the displacement plate 34, and the limiting plate 323 ensures that the connecting rod 322 and the displacement groove 342 will not separate.

[0032] like Figure 1 and Figure 4As shown, further, a pair of positioning plates 15 are mounted on the substrate 1, and positioning blocks 151 are mounted on the pair of positioning plates 15. Bolts 152 are screwed onto the positioning blocks 151, and locking pressure plates 153 are rotatably mounted on the bottom of the bolts 152. The sidewall of the locking pressure plate 153 is slidably connected to the guide rail 154 mounted on the sidewall of the positioning plates 15. The bottom of the locking pressure plate 153 has an anti-slip groove 155. It is necessary to rotate the bolts 152, which will drive the bottom locking pressure plate 153 to slide downward along the guide rail 154. Finally, the locking pressure plate 153 can be pressed against the surface of the copper foil at the bottom, achieving the purpose of locking and fixing. Example

[0033] The difference between the above embodiments and this embodiment is that: Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, an L-shaped bracket 41 is provided on the side wall of the pressing sleeve 4. The L-shaped bracket 41 is connected to the side wall of the base plate 1. A reset cover 5 is installed on the side wall of the L-shaped bracket 41. A connecting plate 421 is installed on the side wall of the pressing rod 42. The end of the connecting plate 421 is connected to the overlapping plate 422. A baffle 411 is slidably provided inside the pressing sleeve 4. The bottom of the baffle 411 is connected to the pressing rod 42. A pressing spring 412 is sleeved on the pressing rod 42 inside the pressing sleeve 4. One end of the pressing spring 412 is connected to the bottom of the pressing sleeve 4, and the other end of the pressing spring 412 is connected to the baffle 411. When the connecting rod 322 moves down, its position changes. At this time, the pressing spring 412 inside the pressing sleeve 4 pushes the baffle 411 to move down. The baffle 411 drives the pressing rod 42 to move down. The connecting plate 421 on the pressing rod 42 drives the overlapping plate 422 to move down, so that the overlapping plate 422 can follow the connecting rod 322 to move down. When the pressing rod 42 moves down, it can push the pressing plate 423 to move down. The pressing plate 423 can squeeze and fix the copper foil at the bottom, which achieves the purpose of positioning. After positioning is completed, the overlapping plate 422 stops moving.

[0034] like Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, in a specific embodiment, a partition 511 is slidably disposed inside the reset cover 5. A reset spring 512 is engaged between one end of the partition 511 and the inner wall of the reset cover 5. The compression direction of the reset spring 512 is the same as the movement direction of the reset rod 51. The reset rod 51 moves through the L-shaped bracket 41. A guide wheel 513 is installed at the end of the reset rod 51. The guide wheel 513 and the guide protrusion 514 are slidably connected. When the pressing plate 423 and the pressing rod 42 slide upward, the guide protrusion 514 on the side wall of the pressing rod 42 slides upward synchronously, causing the guide wheel 513 and the guide protrusion 514 to separate. Consequently, the reset spring 512 inside the reset cover 5 pushes the partition 511 with an outward force, thereby causing the guide wheel 513 and the guide protrusion 514 at the end of the reset rod 51 to contact.

[0035] like Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, a clamping plate 532 is further installed on the substrate 1, located above the flipping plate 53. A barrier plate 531 is installed on the flipping plate 53. A rotating shaft is installed between the strip rod 521 and the flipping plate 53, and the rotating shaft is installed on the side wall of the substrate 1. A strip groove 522 is formed on the strip rod 521, and the strip groove 522 is slidably connected to the synchronizing rod 52. The movement of the reset rod 51 can drive the synchronizing rod 52 to move towards the cutting screw shaft 3. At this time, the synchronizing rod 52 can drive the strip groove 522 on the strip rod 521 to slide, causing the strip rod 521 to rotate as a whole. The strip rod 521 can drive the flipping plate 53 to rotate through the rotating shaft. When the flipping plate 53 is rotated into an inclined state, the copper foil on the flipping plate 53 can slide off, thereby achieving the purpose of automatically discharging waste.

[0036] The implementation principle of the copper foil cutting device capable of cutting copper foil of different thicknesses in this embodiment is as follows: The operator first installs the copper foil on the substrate 1, aligning the end of the copper foil with the barrier plate 531 on the flip plate 53. Then, the operator needs to rotate the bolt 152, which drives the bottom locking plate 153 to slide down along the guide rail 154. Finally, the locking plate 153 can press against the bottom surface of the copper foil, achieving the purpose of locking and fixing.

[0037] Next, the operator needs to turn the crank handle 21, which drives the shift screw shaft 2 to rotate. The shift screw shaft 2 drives the push plate 22 to slide in the mounting groove 13. The position of the mounting seat 221 on the push plate 22 moves synchronously, which in turn drives the cutting screw shaft 3 to move. At this time, the positions of the cutting motor 331 and the cutting blade 332 on the cutting screw shaft 3 change, thereby changing the cutting position of the copper foil and achieving the purpose of changing different cutting thicknesses.

[0038] When a cutting operation is required, the operator first starts the drive motor 313, which drives the cutting screw shaft 3 connected to the output shaft to rotate. A sliding sleeve 31 is engaged on the cutting screw shaft 3, and the sliding seat 311 on the sliding sleeve 31 can slide and limit on the sliding rod 312. When the cutting screw shaft 3 moves, the entire sliding sleeve 31 can slide on the cutting screw shaft 3.

[0039] The positioning sleeve 32 and positioning rod 321 on the sliding sleeve 31 move with the sliding sleeve 31. The connecting rod 322 on the positioning rod 321 slides along the shift groove 342 on the shift plate 34. The limiting plate 323 ensures that the connecting rod 322 and the shift groove 342 will not separate. When the connecting rod 322 slides to the bottom along the shift groove 342, the positioning rod 321 slides synchronously inside the positioning sleeve 32. The connecting rod 322 also drives the mounting bracket 33 on the side wall and the cutting motor 331 to move down, so that the cutting disc 332 contacts the copper foil. The cutting motor 331 can drive the cutting disc 332 to rotate. As the cutting motor 331 and the sliding sleeve 31 move horizontally, the copper foil can be cut as a whole. When the connecting rod 322 slides to the highest point of the shift groove 342, the cutting disc 332 separates from the copper foil, which facilitates the subsequent unloading operation.

[0040] When the connecting rod 322 moves down, its position changes. At this time, the pressing spring 412 inside the pressing sleeve 4 pushes the baffle 411 to move down. The baffle 411 drives the pressing rod 42 to move down. The connecting plate 421 on the pressing rod 42 drives the overlapping plate 422 to move down, so that the overlapping plate 422 can follow the connecting rod 322 to move down. When the pressing rod 42 moves down, it can push the pressing plate 423 to move down. The pressing plate 423 can squeeze and fix the copper foil at the bottom, which achieves the purpose of positioning. After positioning is completed, the overlapping plate 422 stops moving.

[0041] When the cutting is completed, the connecting rod 322 needs to slide upward along the shifting groove 342. At this time, the pressing plate 423 and the copper foil are separated, and the cut waste copper foil has no constraint.

[0042] When the pressing plate 423 and the pressing rod 42 slide upward, the guide protrusion 514 on the side wall of the pressing rod 42 slides upward simultaneously, causing the guide wheel 513 and the guide protrusion 514 to separate. Then, the reset spring 512 inside the reset cover 5 pushes the partition 511 with an outward force, which in turn causes the guide wheel 513 and the guide protrusion 514 at the end of the reset rod 51 to come into contact.

[0043] The movement of the reset rod 51 can drive the synchronizing rod 52 to move towards the cutting screw shaft 3. At this time, the synchronizing rod 52 can drive the strip groove 522 on the strip rod 521 to slide, causing the strip rod 521 to rotate as a whole. The strip rod 521 can drive the flip plate 53 to rotate through the rotating shaft. When the flip plate 53 rotates to an inclined state, the copper foil on the flip plate 53 can slide off, thereby achieving the purpose of automatically discharging waste.
