Description

Technical Field

[0001] This utility model relates to an adjustable circuit board copper foil cutting device, specifically an adjustable circuit board copper foil cutting device, belonging to the field of copper foil cutting technology. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as the conductor in the PCB. It readily adheres to insulating layers, accepts printed protective layers, and, after etching, forms the circuit pattern. In the prior art, an electrolytic copper foil cutting device with publication number CN117381865A relates to the field of copper foil cutting. It includes a base, a support leg fixedly connected to the bottom of the base, a winding sleeve mechanism and a placing sleeve mechanism fixedly connected to the base, a synchronous belt mechanism between the winding sleeve mechanism and the placing sleeve mechanism, a mounting seat on the base, and a plurality of directional roller mechanisms on the mounting seat.

[0003] In electronic circuit board production, copper foil cutting is a crucial step. Traditional copper foil cutting equipment typically uses fixed clamping devices to hold the copper foil in place, ensuring stability during the cutting process. However, this fixed clamping method has several problems in practical applications. First, after fixing the copper foil, the clamping device obstructs the copper foil's transport, affecting its smooth flow. Second, traditional clamping devices cannot quickly release the copper foil after cutting, causing uncut portions to be unable to proceed to the next processing step in a timely manner, thus impacting production efficiency.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The transmission component 4 includes a transmission frame 41. The bottom of the transmission frame 41 is provided with a mounting groove. A drive roller 42 and a driven roller 43 are rotatably connected to the inner wall of the mounting groove.

The inner plate 45 is fixedly connected to the inner wall of the mounting groove.

[0022] Please see Figure 1 and Figure 2 Four guide rods 7 are fixedly connected between the top wall inside the mounting frame 3 and the top wall of the base 1.

The second driving roller 52 and the second driven roller 53 are rotatably connected to the inner wall of the second mounting groove. The second transmission belt 54 is connected between the second driving roller 52 and the second driven roller 53. The top wall inside the second transmission belt 54 contacts an inner plate 55. The inner plate 55 is fixedly connected to the inner wall of the second mounting groove. Specifically, protective covers can be installed on one side of conveyor frame 1 41 and conveyor frame 2 51 to cover bevel gear 1 10 and bevel gear 2 11.

[0024] Please see Figure 1 and Figure 2A hexagonal rod 8 is rotatably connected to one side of the mounting frame 3. Two sleeves 9 are slidably sleeved on the outside of the hexagonal rod 8. Two sleeve plates are rotatably sleeved on the outside of the sleeves 9. The four sleeve plates are respectively fixedly connected to one side of the first conveyor frame 41 and the second conveyor frame 51. A bevel gear 10 is fixedly sleeved on the outside of the sleeves 9. A bevel gear 21 is meshed with one side of the bevel gear 10. The two bevel gears 211 are respectively fixedly connected to one end of the first drive roller 42 and one end of the second drive roller 52. A servo motor 14 is installed on the base 1. The output shaft of the servo motor 14 is fixedly connected to one end of the hexagonal rod 8. Specifically, the servo motor 14 is electrically connected to the power supply. The models of the servo motor 14, cylinder 23, and cylinder 62 are not limited, and the specific models are subject to the equipment.

[0025] Please see Figure 1 and Figure 2 The cutting assembly 2 includes a fixed frame 21 installed on the top of the base 1. The inner walls on both sides of the fixed frame 21 are formed with grooves. A cutter 22 is slidably connected between the two grooves. A cylinder 23 is installed on the top wall inside the fixed frame 21. The piston rod end of the cylinder 23 is fixedly connected to the top of the cutter 22. An anvil 24 is installed on the top of the base 1. The anvil 24 is located directly below the cutter 22, and a cutting groove is opened on the top of the anvil 24. Specifically, the tangent groove at the top of the anvil 24 provides an accurate cutting path for the cutter 22, ensuring cutting precision and quality. When the cutter 22 is cutting, the servo motor 14 needs to be stopped. During the cutting process, the anvil 24 not only supports the copper foil but also protects the conveyor belt 44 of the transmission assembly 4 from being cut by the cutter 22. This ensures that the transmission assembly 5 can continue to function normally after cutting, maintaining stable clamping and transmission of the uncut copper foil.

[0029] Working principle: Transmission component 4 and transmission component 5 cooperate to clamp the copper foil; conveyor belt 44 operates under the drive of drive roller 42 and driven roller 43, and conveyor belt 54 operates under the drive of drive roller 52 and driven roller 53; when the copper foil is placed between transmission component 4 and transmission component 5, the relative movement of transmission belt 44 and conveyor belt 54 clamps the copper foil and transports it stably.

[0030] The lifting component 6 controls the up-and-down movement of the lifting plate 61 via cylinder 62. When it is necessary to adjust the distance between the first transmission component 4 and the second transmission component 5 to accommodate copper foil of different thicknesses, cylinder 62 drives the lifting plate 61 to rise or fall, thereby moving the first transmission component 4 as a whole, realizing the adjustment of the clamping force and position of the copper foil, and adapting to copper foil of different thicknesses.

[0031] When it is necessary to cut copper foil, the cutter 22 in the cutting assembly 2 is driven downward by the cylinder 23 to cooperate with the anvil 24 to complete the cutting action.
