Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology, specifically relating to a transverse cutting machine for CCL copper clad laminates. Background Technology

[0002] A cutting machine is a CNC device used for cutting and slitting sheet materials. It supports die-free cutting and multiple operating languages. The equipment can process 12 types of flexible materials, including leather, fabric, rubber, and sponge, and is suitable for packaging printing, advertising inkjet printing, automotive interiors, and other fields.

[0003] Copper-clad laminate (CCL) is a plate-like material formed by bonding a layer of copper foil to one or both sides of an insulating substrate (usually made by impregnating a reinforcing material with resin) through a hot-pressing process. During the cutting of CCL copper-clad laminates, care must be taken to avoid resin burrs or rough edges due to the copper foil coating, which can affect subsequent processing and circuit accuracy. Furthermore, cutting stress during the copper foil cutting process may cause delamination between the copper foil and the substrate, or micro-cracks at the edges, affecting conductivity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a transverse cutting machine for CCL copper clad laminates, including a base support, side plates fixedly installed on both sides of the top of the base support, and a protective cover fixedly installed on the outside of the side plates. A connecting frame is fixedly installed on the top of the protective cover, and a top sealing plate is fixedly installed on the top of the connecting frame. A reduction motor is fixedly installed on the base support. A cutting mechanism that moves through the reduction motor is installed on the top of the side plates. A material guiding mechanism is installed on the connecting frame located at the position of the cutting mechanism. A positioning and clamping mechanism that cooperates with the cutting mechanism to perform cutting is fixedly installed on the top of the material guiding mechanism.

[0005] As a further preferred technical solution of this utility model; the output end of the geared motor is connected to a drive shaft, and the side plate is provided with an opening at the position of the drive shaft and a square bearing seat is fixedly installed on the outside. The two ends of the drive shaft pass through the side plate and are connected to eccentric wheels through the square bearing seats. A slide rail frame is fixedly installed on the side plate at the top position of the eccentric wheel. A guide rod is slidably installed on the slide rail frame. The guide rod and the eccentric wheel are connected and installed through two sets of spherical bearings with internal threads, and the spherical bearings with internal threads are connected and installed through a connecting screw.

[0006] During the rotation of the drive shaft driven by the geared motor, the drive shaft drives the eccentric wheels connected at both ends to rotate. Under the connection of the spherical bearing with internal thread and the connecting screw, the eccentric wheels drive the guide rod to slide up and down on the slide rail frame.

[0007] As a further preferred technical solution of this utility model, the cutting mechanism includes a lower cutter seat fixedly installed between the tops of the side plates, a lower cutter fixedly installed on the top of the lower cutter seat, an upper cutter seat installed on the back of the connecting frame at the top position of the lower cutter seat, and an upper cutter fixedly installed at the bottom of the upper cutter seat. The two ends of the upper cutter seat are fixedly installed with the guide rod.

[0008] The guide rod is driven by a geared motor to move up and down, which in turn causes the upper cutter holder, which is fixedly installed with the guide rod, to move up and down, thereby cutting the CCL copper-clad laminate.

[0009] As a further preferred technical solution of this utility model, the material guiding mechanism includes a bridge plate fixedly installed between the connecting frames at the top position of the lower cutter, a transition roller fixedly installed on the back of the upper cutter holder, and a fixing frame fixedly installed on the top of the connecting frame.

[0010] The CCL copper-clad laminate is guided by the transition roller. When it extends to the bridge plate, the upper cutter head is driven by the geared motor to slide down, so that the upper cutter cuts the CCL copper-clad laminate to achieve a transverse cutting effect.

[0011] As a further preferred technical solution of this utility model, the positioning and clamping mechanism includes two sets of fixed seats fixedly installed on the fixed frame, an air blowing pipe fixedly installed through the fixed seats, and three sets of cylinders fixedly installed at the bottom of the fixed frame. A cylinder pressure plate is connected and installed at the bottom of the cylinder, and multiple sets of air blowing holes are opened on the air blowing pipe.

[0012] The cylinder and the air blowing port are connected by a sealed PVC pipe. After the air blowing pipe is connected to the air compressor, compressed air is introduced through the air blowing pipe and delivered to the cylinder through the PVC pipe.

[0013] As a further preferred technical solution of this utility model; a mounting bracket is fixedly installed between the top of the base bracket and the reduction motor, two sets of PVC plates are fixedly installed on the protective cover, and a flip-up protective plate is installed on the back of the protective cover at the position of the top sealing plate by hinge.

[0014] After cutting is completed, the internal structure of the cutting mechanism can be maintained or repaired by flipping over the protective plate. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The guide rod is driven by a geared motor to move up and down, which in turn causes the upper cutter holder, which is fixedly installed on the guide rod, to move up and down. The speed at which the upper cutter descends is ensured by the eccentric wheel and the spherical bearing with internal thread, thereby achieving rapid cutting of CCL copper-clad laminate. Similarly, the designated electrical control system connected to the geared motor outputs current to the geared motor in real time and accurately according to the internal algorithm, thereby controlling its speed. Based on the set cutting length and material characteristics, this reduces the occurrence of resin burrs or rough edges on the copper foil during the cutting process, reduces the impact on subsequent processing and circuit accuracy, and achieves clean cutting of CCL copper-clad laminate without burrs or chipping.

[0016] 2. The air circuit is connected to the cylinder and the air blowing port through a sealed PVC pipe. After the air blowing pipe is connected to the air compressor, compressed air is introduced through the air blowing pipe and then delivered to the cylinder through the PVC pipe. Driven by air pressure, the cylinder pushes the cylinder pressure plate downward, applying a stable pressing action to the CCL copper-clad laminate. This pressing mechanism effectively assists the cutting mechanism in completing the cutting operation, ensuring that the CCL copper-clad laminate remains in a stable position throughout the cutting process, thereby guaranteeing cutting accuracy and quality.

[0019] This specific embodiment is a transverse cutting machine for CCL copper clad laminates.

[0020] When cutting CCL copper-clad laminates, it is important to note that because the surface is covered with copper foil, resin burrs or rough edges may be generated on the cut metal edges, which will affect subsequent processing and circuit accuracy. Moreover, during the copper foil cutting process, the cutting stress may cause the copper foil to delaminate from the substrate or cause micro-cracks on the edges, affecting conductivity.

[0021] Example 1: A transverse cutting machine for CCL copper-clad laminates includes a base support 1, side plates 3 fixedly installed on both sides of the top of the base support 1, and a protective cover 31 fixedly installed on the outside of the side plates 3. A connecting frame 43 is fixedly installed on the top of the protective cover 31, and a top sealing plate 33 is fixedly installed on the top of the connecting frame 43. A geared motor 2 is fixedly installed on the base support 1. A drive shaft 21 is installed through and connected to the output end of the geared motor 2. A through-hole is provided on the side plate 3 at the position of the drive shaft 21, and a square bearing seat 22 is fixedly installed on the outside. Eccentric wheels 23 are connected to both ends of the drive shaft 21 through the side plate 3 and connected by the square bearing seats 22. A slide rail frame 35 is fixedly installed on the side plate 3 at the top position of the eccentric wheel 23. A guide rod 26 is slidably installed on the slide rail frame 35. The guide rod 26 and the eccentric wheel 23 are connected and installed by two sets of internally threaded spherical bearings 24, and the internally threaded spherical bearings 24 are connected and installed by a connecting screw 25. During the rotation of the transmission shaft 21 driven by the geared motor 2, the transmission shaft 21 drives the eccentric wheels 23 connected at both ends to rotate. The eccentric wheels 23, connected by the internally threaded spherical bearing 24 and the connecting screw 25, drive the guide rod 26 to move up and down on the slide rail frame 35, thus achieving the driving effect of the geared motor 2. A cutting mechanism 6, which is moved by the geared motor 2, is installed on the top of the side plate 3. The cutting mechanism 6 includes a lower blade holder 61 fixedly installed between the tops of the side plates 3, a lower cutting blade 62 fixedly installed on the top of the lower blade holder 61, an upper blade holder 63 installed on the back of the connecting frame 43 at the top position of the lower blade holder 61, and an upper cutting blade 64 fixedly installed at the bottom of the upper blade holder 63. Both ends of the upper blade holder 63 are fixedly installed to the guide rod 26. The geared motor 2 drives the guide rod 26 to move up and down, causing the upper blade holder 63, fixedly installed to the guide rod 26, to move the upper cutting blade 64 up and down, thereby cutting the CCL copper-clad laminate.

[0022] The geared motor 2 is connected to the designated electrical control system of the equipment. A physical and communication connection is established with the system via a dedicated interface such as a servo driver or frequency converter. The electrical control system receives cutting instructions from a preset program and, through an internal algorithm, precisely and in real-time outputs current to the geared motor 2, thereby controlling its speed. This achieves clean cutting of the CCL copper-clad laminate without burrs or chipping, based on the set cutting length and material characteristics. The eccentric wheel 23 and the spherical bearing 24 with internal threads ensure the descending speed of the upper cutting blade 64, achieving rapid cutting of the CCL copper-clad laminate. Similarly, the designated electrical control system connected to the geared motor 2, according to its internal algorithm, precisely and in real-time outputs current to the geared motor 2, thereby controlling its speed. This reduces resin burrs or rough edges on the copper foil during cutting, minimizing the impact on subsequent processing and circuit accuracy, and achieving clean cutting of the CCL copper-clad laminate without burrs or chipping. A material guiding mechanism 4 is installed on the connecting frame 43 located at the cutting mechanism 6. The material guiding mechanism 4 includes a bridge plate 42 fixedly installed between the connecting frames 43 at the top of the lower cutter 62, a transition roller 41 fixedly installed on the back of the upper cutter holder 63, and a fixing frame 44 fixedly installed on the top of the connecting frame 43. The CCL copper-clad laminate is guided by the transition roller 41. When it extends onto the bridge plate 42, the upper cutter holder 63 is driven down by the geared motor 2, so that the upper cutter 64 cuts the CCL copper-clad laminate, achieving a transverse cutting effect. A mounting bracket 11 is fixedly installed between the top of the base bracket 1 and the geared motor 2. Two sets of PVC boards 32 are fixedly installed on the cover 31. A flip-over protective plate 34 is installed on the back of the cover 31 at the position of the top sealing plate 33 via a hinge. After cutting, the internal structure of the cutting mechanism 6 can be maintained or repaired by flipping the flip-over protective plate 34.

[0023] A positioning and clamping mechanism 5 is fixedly installed on the top of the material guiding mechanism 4 to cooperate with the cutting mechanism 6 for cutting. The positioning and clamping mechanism 5 includes two sets of fixed seats 54 fixedly installed on the fixed frame 44, an air blowing pipe 53 fixedly installed through the fixed seats 54, and three sets of cylinders 51 fixedly installed at the bottom of the fixed frame 44. A cylinder pressure plate 52 is connected to the bottom of the cylinder 51, and multiple sets of air blowing holes 55 are opened on the air blowing pipe 53. The cylinder 51 and the air blowing holes 55 are connected by a sealed PVC pipe to realize the air circuit. After the air blowing pipe 53 is connected to the air compressor, compressed air is introduced through the air blowing pipe 53 and delivered to the cylinder 51 through the PVC pipe. Under the pneumatic drive, the cylinder 51 pushes the cylinder pressure plate 52 to move downward, applying a stable pressing action to the CCL copper-clad laminate. This pressing mechanism effectively assists the cutting mechanism 6 in completing the cutting operation, ensuring that the CCL copper-clad laminate remains in a stable position throughout the cutting process, thereby ensuring cutting accuracy and quality.
