Description

[0001] The invention belongs to the technical field of copper foil cutting, and in particular relates to an edge cutting device capable of cutting copper foils of different thicknesses. Background Art

[0002] Copper foil has good electromagnetic shielding effect and is widely used in electronics, communications, medical and other fields. Copper foil production generally requires edge trimming. During the copper foil production process, the size of the copper foil is different, so the cutting thickness needs to be controlled during edge trimming.

[0003] However, it is found during the use of the existing copper foil trimming device that after the copper foil is cut, the cut waste is still on the base. At this time, the operator needs to clean it with a brush, which results in manual cleaning after each cutting. The operation is more troublesome. During the cutting operation, the operator needs to clamp and fix the two ends of the cutting position to ensure that the cutting position does not shift. However, it needs to be unlocked separately after each cutting, which also causes troublesome operation during the cutting process and is not conducive to improving the cutting efficiency. Before the cutting operation, the cutter needs to be controlled to move to the copper foil separately to ensure that the cutting can be carried out smoothly. The operation is also troublesome.

The positioning rod on the positioning sleeve slides along the shift groove at this time. When the positioning rod moves to the low-lying part of the shift groove, the synchronously connected cutting motor and cutting blade can move downward and automatically move toward the copper foil, which can achieve the purpose of automatic feeding and is more convenient to operate.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in a specific embodiment, a cutting notch 12 is opened on the substrate 1, and a flip plate 53 is rotatably installed on the side wall of the cutting notch 12, and a gap is left between the flip plate 53 and the side wall of the cutting notch 12, and a guide plate 121 is installed at the bottom of the cutting notch 12, and 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 can facilitate the sliding of waste materials at a later time.

The feed port of the side wall of the collecting box 11 corresponds to the end of the guide plate 121, and the waste material sliding down from the guide plate 121 can fall onto the drawer 112 in the collecting box 11. Later, the drawer 112 can be moved by pulling the handle 113 to clean the waste material inside the drawer 112. Example

[0030] The difference between the above embodiment and this embodiment is that: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a mounting groove 13 is opened on the base plate 1, and the shift screw shaft 2 movably passes through the mounting groove 13. A crank 21 is installed at the end of the shift screw shaft 2, and the push plate 22 is slidably set on the mounting groove 13. The center position of the mounting groove 13 is covered with a cover plate 131. The shift screw shaft 2 is driven to rotate by the crank 21, and 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, and then the cutting screw shaft 3 can be driven to move. At this time, the positions of the cutting motor 331 and the cutting blade 332 on the cutting screw shaft 3 change, so that the cutting position of the copper foil can be changed, thereby achieving the purpose of changing different cutting thicknesses. A pair of support legs 14 are fixedly installed at the bottom of the base plate 1, and a reinforcing rib 141 is installed between the pair of support legs 14. The reinforcing rib 141 is cross-distributed, and the support legs 14 play a supporting purpose. A pair of mounting seats 221 are installed on the push plate 22, and the cutting screw shaft 3 is rotatably installed on the mounting seats 221. The side wall of the mounting seat 221 and the housing of the driving motor 313 are connected to each other. A sliding rod 312 is installed through the inside of the mounting seat 221, and a sliding seat 311 is slidably arranged on the sliding rod 312. The sliding seat 311 and the bottom of the sliding sleeve 31 are connected to each other. Start the driving motor 313, and the cutting screw shaft 3 connected to the output shaft is driven to rotate by the driving motor 313. The cutting screw shaft 3 is meshed with a sliding sleeve 31, and the sliding seat 311 on the sliding sleeve 31 can slide and limit on the sliding rod 312, so that when the cutting screw shaft 3 moves, the entire sliding sleeve 31 can be driven to 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, and a limiting plate 323 is installed at the end of the connecting rod 322, and the diameter of the limiting plate 323 is greater 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 substrate 1. The positioning sleeve 32 and the positioning rod 321 on the sliding sleeve 31 move with the sliding sleeve 31, and the connecting rod 322 on the positioning rod 321 slides along the displacement groove 342 on the displacement plate 34 at this time, 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 installed on the base plate 1, and a positioning block 151 is installed on the pair of positioning plates 15. A bolt 152 is screwed on the positioning block 151, and a locking pressure plate 153 is rotatably installed at the bottom of the bolt 152. The side wall of the locking pressure plate 153 is slidably connected with a guide rail 154 installed on the side wall of the positioning plate 15, and an anti-slip groove 155 is provided at the bottom of the locking pressure plate 153. The bolt 152 needs to be rotated, and the locking pressure plate 153 at the bottom is driven by the bolt 152 to slide downward along the guide rail 154, and finally the locking pressure plate 153 can be pressed against the copper foil surface at the bottom, so as to achieve the purpose of locking and fixing. Example

[0033] The difference between the above embodiment and this embodiment is that: Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the side wall of the pressing sleeve 4 is provided with an L-shaped bracket 41, the L-shaped bracket 41 is interconnected with the side wall of the substrate 1, the side wall of the L-shaped bracket 41 is installed with a reset cover 5, the side wall of the pressing rod 42 is installed with a connecting plate 421, the end of the connecting plate 421 is interconnected with the lap plate 422, a baffle 411 is slidably arranged inside the pressing sleeve 4, the bottom of the baffle 411 and the pressing rod 42 are interconnected, a pressing spring 412 is sleeved on the pressing rod 42 located inside the pressing sleeve 4, one end of the pressing spring 412 is interconnected with 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 downward, the position of the connecting rod 322 changes. At this time, the pressing spring 412 inside the pressing sleeve 4 pushes the baffle 411 to move downward, and the baffle 411 drives the pressing rod 42 to move downward. The connecting plate 421 on the pressing rod 42 drives the lap plate 422 to move downward, so that the lap plate 422 can move downward with the connecting rod 322. When the pressing rod 42 moves downward, it can push the pressing plate 423 to move downward. The pressing plate 423 can squeeze and fix the copper foil at the bottom, thereby achieving the purpose of positioning. After positioning is completed, the lap plate 422 stops moving.

[0034] like Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, in a specific embodiment, a partition 511 is slidably arranged inside the reset cover 5, and a reset spring 512 is clamped 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 moving direction of the reset rod 51. The reset rod 51 movably passes through the L-shaped bracket 41, and 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, resulting in the separation of the guide wheel 513 and the guide protrusion 514 at this time, and then the reset spring 512 inside the reset cover 5 at this time pushes the partition 511 at this time with an outward force, thereby driving the guide wheel 513 at the end of the reset rod 51 to contact the guide protrusion 514.

[0035] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, further, a card plate 532 is installed on the substrate 1, and the card plate 532 is located above the flip plate 53. A blocking plate 531 is installed on the flip plate 53. A rotating shaft is installed between the strip rod 521 and the flip plate 53, and the rotating shaft is installed on the side wall of the substrate 1. A strip groove 522 is opened on the strip rod 521, and the strip groove 522 and the synchronization rod 52 are slidably connected. The movement of the reset rod 51 can drive the synchronization rod 52 to move toward the side of the cutting screw shaft 3. At this time, the synchronization rod 52 can drive the strip groove 522 on the strip rod 521 to slide, driving 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.

[0036] The implementation principle of the device for cutting copper foils of different thicknesses in this embodiment is as follows: The operator first installs the copper foil on the substrate 1 and aligns the end of the copper foil with the blocking plate 531 on the flip plate 53. Then the operator needs to turn the bolt 152 to drive the locking pressure plate 153 at the bottom to slide downward along the guide rail 154. Finally, the locking pressure plate 153 can be squeezed with the surface of the copper foil at the bottom to achieve the purpose of locking and fixing.

[0037] Then the operator needs to turn the crank 21, which drives the shift screw shaft 2 to rotate. The shift screw shaft 2 drives the push plate 22 to slide in the installation groove 13, and the position of the mounting seat 221 on the push plate 22 moves synchronously, thereby driving 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 cutting operation is required, the operator first starts the drive motor 313, and drives the cutting screw shaft 3 connected to the output shaft to rotate through the drive motor 313. A sliding sleeve 31 is meshed 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. Then, when the cutting screw shaft 3 moves, the entire sliding sleeve 31 can be driven to slide on the cutting screw shaft 3.

[0039] The positioning sleeve 32 and the positioning rod 321 on the sliding sleeve 31 move with the sliding sleeve 31, and the connecting rod 322 on the positioning rod 321 slides along the shift groove 342 on the shift plate 34 at this time, and the limit 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, and the connecting rod 322 also drives the side wall mounting bracket 33 and the cutting motor 331 to move downward, so that the cutting blade 332 contacts the copper foil, and the cutting motor 331 can drive the cutting blade 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 blade 332 is separated from the copper foil, which is convenient for subsequent unloading operations.

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

[0041] When the cutting is completed at a later stage, the connecting rod 322 needs to slide upward along the displacement groove 342, at which time the pressing plate 423 and the copper foil are separated, and the waste copper foil cut out at this time has no restraining force.

[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 synchronously, causing the guide wheel 513 and the guide protrusion 514 to be separated at this time, and then the reset spring 512 inside the reset cover 5 pushes the partition 511 with an outward force, thereby driving the guide wheel 513 and the guide protrusion 514 at the end of the reset rod 51 to contact.

[0043] The movement of the reset rod 51 can drive the synchronization rod 52 to move toward the side of the cutting screw shaft 3. At this time, the synchronization rod 52 can drive the strip groove 522 on the strip rod 521 to slide, driving 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.
